The prevent invention discloses a defrosting machine column fixed support with an inclined flat leg, including a defrosting machine (1), a connecting support (2), a pedestal bolt (3), and a pedestal (4). The connecting support (2) includes an anti-tilting guide barrel (21), a fixed pillar (22), a rib plate (23), and a connecting plate (24). The pedestal (4) includes a pedestal plate (41) and a flat leg (42). The pedestal bolt (3) is used for fixedly connecting the connecting support (2) with the pedestal (4). The pedestal plates are hit into the soil so as to solve digging difficulties and low efficiency of a small diameter mounting deep hole with high accuracy requirements; each pedestal plate is respectively vertically provided with two intersecting flat legs in an inclined mode, thus balancing forces in each direction and stabilizing the defrosting machine column. The holes on the pedestal plates can integrate the soils on the inner side and outer side and two sides into one body, thus stabilizing the defrosting machine. In addition, the connecting support is employed, and standard tubes replace conventional non-standard tubes, thus saving on material cost, and transport and storage are also convenient. The support is simple in structure, convenient to implement, can be applied on pebbled land, not only reduces labour intensity when mounting, but also improves the anti-sinking, anti-horizontal torsion and anti-tilting abilities of the defrosting machine column, improves defrosting machine work reliability, and improves mounting efficiency and economic benefits of the defrosting machine.

A stage smoke machine with a fast spray gas column includes an oil barrel, an oil pump, a gas tank, a first electromagnetic valve, a heater, a gas-filling device and a controller. In case of gas loss in the gas tank, the gas tank is replenished with the gas by the gas-filling device so that the gas pressure in the gas tank can be maintained at a pressure sufficient to fast spray smoke oil into the heater, thereby ensuring that every time the smoke machine is started, the smoke machine can quickly show a high level stage effect of fast sprayed smoke. Further, an electromagnetic valve module is formed by installing at least two electromagnetic valves integrally on a base.

Systems and methods of use pertaining to a rocket-type heating and cooking system feature three distinct cooking surfaces designed for simultaneous use and may be dismantled and transported for use in a variety of environments, including use as a heating and cooking device in the home as a fireplace insert, use outdoors in a hiking or camping setting, or use in a developing-world application as a third-world outdoor or indoor kitchen. The heating and cooking system features a combustion chamber and exhaust chimney having optimized dimensions to achieve maximum combustion efficiency, which translates to increased heating and cooking capacities as well as reduced smoke exhaustion. Other embodiments are also disclosed.

A system, device and method for delivering CO2 or other gases to plants in fields, orchards, vineyards and the like. A stake with a windbreak structure and gaseous emitters on the upwind side creates a leeward wind eddy surrounding a plant, such as an orchards sapling. This establishes and maintains a gaseous microclimate beneficial to the plant. The device delivers CO.sub.2 gas to a plant in an agricultural field, orchard, grove, orchard of the like. The device includes an elongated base adapted to be adjustably placed on the ground a predetermined distance from the plant, upwind of the plant. A wind foil is adjustably connected to the base along its elongated length. The wind foil has a curvilinear geometry with a first face having a generally convex configuration, and a second face having a generally concave configuration. An emitter assembly is disposed on the second face of the wind foil. A gas supply conduit is communicatively connected to the emitter and adapted to be connected to a gas supply. A system including multiple devices and a method of making and using the device and system are also disclosed.
