This disclosure relates to systems, methods and apparatuses for removing precipitation from an exterior of a building in an expedited and automated fashion. The precipitation removal system includes one or more sweeper assemblies and one or more hoisting assemblies. The sweeper assemblies are suspended from the roof, ledge or other portion of a building. The hoisting assemblies assist the sweeper assemblies with vertically traversing the exterior of the building. As a sweeper assembly vertically traverses the side of the building, precipitation that accumulates on the exterior of the building is removed. The sweeper assemblies can remove precipitation from connecting structures on the exterior of the building which are used by building maintenance personnel to perform maintenance operations on the exterior of the building.

An article of manufacture for providing an ice dam hammer is made from an ice breaking head, coupled to a tubular aluminum adapter designed to connect to the detachable handle of an existing article of manufacture known as a roof rake. The ice breaking head includes a main breaking head whereas the lower/bottom side of the ice breaking head has a plurality of blunt protrusions. The upper/top side of the ice braking head has two flat protrusions. The one side of the hammer head is pointed. The second side of the hammer head has a rounded end.

The present invention relates to a system and method for preventing collapse of a green house by snow load, more particularly, relates to preventing collapsing of the green house due to unexpectedly occurrable heavy snowfall, by calculating the snow load per unit area based on the amount of snow deposited on the green house roofs measured by radar (radio detection and ranging) sensors, by analyzing whether the green house can withstand snow loads by comparing the calculated snow load with structural information of the green house, and by driving a snow removing device according to the result of the analysis, in which the snow removing device comprises a heater, a blower, a vibrator, or the combinations thereof installed in the green house or providing an emergency message to the user terminal held by an administrator.

An accessory for a solar panel assembly includes a bracket defining an elongated portion extending in a first direction and including a slot, a connector coupled to the bracket and configured to engage at least one panel frame of the solar panel assembly, and a fence member including a first portion and a second portion. The first portion including a planar surface oriented at an angle relative to the bracket portion, and the second portion includes a projection that removably engages the slot.

A manually operated snow removal device designed for generally flat surfaces such as roofs includes a box-shaped device having a scalloped or undulating front and rear edge to cut through the snow; a leading bottom edge which protrudes from the box-shaped device to prevent the device from falling off roofs and a load belt made of a length of HPDE material for transporting the snow loaded on the load belt. A telescopic pole attaches to the device and allows the operator to remove approximately 10 square feet of snow and subsequently moved that snow to a desired location on the roof. The operator than moves the device such that the load belt folds over the edge of the roof dumping the snow in a desired location.

A dispenser attachment device configured to attach to a conventional snow roof rake tool having a handle, the dispenser attachment device including a reservoir compartment to store and release a de-icing material, an attachment member configured to detachably couple to the tool, and a stabilizer having an upper member and a lower member extending therefrom to stabilize the reservoir compartment when releasing the de-icing material, wherein the reservoir compartment stores the de-icing material when in a first position and dispenses the de-icing material when the reservoir compartment is rotated to a second position.

An ice melting and clearing rod includes an ice melting chemical compound including calcium chloride, sodium chloride, potassium chloride, amide, and/or glycol, forming a substantially cylindrical member. The substantially cylindrical member includes: an outer surface including: multiple grooves that run along a length of the cylindrical member, the grooves being evenly spaced about a circumference of the cylindrical member; and a textured surface along at least a portion of the outer surface, the textured surface providing resistance in one direction along the length of the cylindrical member; and a set of through-holes adapted for use as placement features, wherein each through-hole in the set of through-holes is perpendicular to the length of the cylindrical member, where: the rod is adapted for use on a sloped roof, the outer surface is formed by the ice melting compound, and a shape of the substantially cylindrical member is retained without any external container.

A ski device for use in combination with a snow removal device (such as a roof rake). The ski device includes ski portions that may be used to protect a surface (such as a roof surface) from damage by preventing a head of the snow removal device from directly contacting and scraping along the surface from which snow, ice, and/or debris is to be removed. The ski device also allows the amount of clearance between the head of the snow removal device and the surface to be adjusted. This allows a user to position the ski device to provide for a desired amount of clearance, which allows for adjustment of the amount of snow, ice, and/or debris that is to be removed, as well to allow for clearance of other structures (such as rain deflectors, etc.) on the surface.

A robot for clearing snow has a main body; a traction arrangement enabling motion of the robot on snow lying on a roof; a snow-removal device; and at least one depth sensor. A processing and control unit controls at least one motor to direct the robot to follow a snow-clearing path; receives a depth signal from the depth sensor(s); and, as a function of the depth signal, actively controls a snow-clearing depth by actuating the snow-removal device and, as the robot follows the snow-clearing path, adjusting a vertical snow-clearing distance so as to leave a layer of snow of a pre-determined depth on the roof after clearing and to prevent contact by the snow-removal device with a surface of the roof. During snow removal, no part of the snow-removal device contacts the roof surface other than at most the traction arrangement.
