DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0027] Referring now to the drawings, a system for removing a test seal part from a vent positioned on a roof of a structure and being removable without requiring a person on site to accomplish the same is generally referred to by the numeral 10. As noted in FIG. 1 Prior Art, there is provided a vent pipe 12 which extends through a roof 14 which, by conventional code, extends a minimum height from the roof 14 to a discharge opening 16. The vent pipe 12 includes a test cap 18 which is conventionally sealed in a fixed way (typically epoxy) until a standardized pressure test is conducted. Once the pressure test is conducted, the test cap 18 is removed as previously described above by cutting or otherwise knocking it off the pipe.

[0028] As can be seen in the embodiment represented in FIG. 2, the current system 10 has a removable test seal part 20, which can include a test cap 22 having a sealable connectable neck 24 which can have a seal surface to prevent fluid flow thereby, and retains the part 20 in place within the vent pipe 12 to prevent flow therethrough at least up to a predetermined pressure, e.g., 5 lbs and/or vacuum at such pressure.

[0029] The test cap 22 can include an attachment surface 26, such as a wire ring or loop 26 made of a suitable strength material and affixed to the test cap 22 and extending from the test cap 22 in a manner to not interfere with the installation of a boot 28.

[0030] A remote controlled apparatus 30 in conjunction with a remote controller 32 is provided for removing the test seal part 20. In this embodiment, the remote controlled apparatus 30 includes an unmanned aerial vehicle (UAV) 33 which is remote controlled aircraft (e.g. flown by a pilot at a ground control station) or can fly autonomously based on pre-programmed flight plan or more complex dynamic automation systems by remote controller 32 such as a computer based, wherein the UAV 33 is equipped with means for removing 34 (a hook) the test seal part 20 from the plumbing vent pipe 12 post inspection.

[0031] In a preferred version, it is envisioned the test seal part 20 includes a connection removal surface 26, such a looped cable or other open surface formed on the cap 22, to which the means for removing 34 connects for enabling removal. The means for removing 34 can include hook or other tool such as a robotic arm for connection to the connection removal surface 26.

[0032] In another embodiment as seen in FIGS. 3A, 3B and 4, there is provided remote controlled apparatus 33. In the cases of FIGS. 3A and 3B there is provided a battery powered actuator 40. For example, the actuator can include a solenoid which comprises electromagnets made of a coil of copper wire with an armature 42 (a slug of metal) in the middle. When the coil is energized, the slug is pulled or pushed as a function of point of connection on the test cap 22 (e.g., a disk which slides through a slot 15 in the pipe 14) connected to the armature into the center of the coil. This makes the solenoid able to pull (from one end) or push (from the other). This solenoid in particular is very small, with a 20 mm long body and a ‘captive’ armature 42. This means that when activated with 5 VDC, the solenoid moves and then the voltage is removed leaving the disk in a displaced position, which is breaks the seal in the pipe and enables air to escape through the pipe. The actuator 40 can have a receiver 44 operably disposed therewith in manner to actuate the test cap 22 out of sealable connection with the vent pipe 12 by way of remote control 32 for sending a signal to the receiver 44 causing actuation of the test cap 22 out of sealed connection. A seal ring 46 can be provided in the pipe 12 to ensure a seal between the pipe 12 and the test cap 22.

[0033] Still another aspect of the invention is to provide a locating device 36, such as an identification chip, such as an NFC chip, in the test seal part 20 and providing the UAV 30 with a complementary locating device 38, such as an NFC locating device, for aiding in removal of the test seal part 20, 20′.

[0034] Additionally, it is envisioned there can be provided transducer in the test seal part which permits transmission of signal indicative of a pressure within the pipe and this can be operably connected to the test seal part 20, 20′.

[0035] To remove the seal part, the remote controlled apparatus 33 and/or remote control 32 are initiated. Either directly or indirectly the remote controlled apparatus 33 and/or remote control 32 connects to the seal part 20, 20′ causing the test cap 22 to be moved breaking a seal with the vent pipe 14 to permit air to pass therethrough.

[0036] In the embodiment of FIG. 4, there is provided a in the pipe 14 an inner ledge 50 which can be formed as part of a coupling 52 or integral in the pipe 14. Test cap 54 is disposed on the ledge 50. A wire 56 is operably disposed around the test cap 54 which by way of example is circular and the wire 56 and has a portion 57 which is preferably wrapped 360 degrees about the test cap 54 and has an end 59 which can be mechanically or chemically attached to the test cap 54. A sealant, such as silicon seal 61, can be disposed about the perimeter of the cap 54 within the pipe 14 and seal about the same with an end 58 of the wire 56 extending thereby or therethrough in a sealed manner and which extends out of the tube 14.

[0037] The end 58 can be provided with an eyelet 60 formed thereon to permit the hook 34 of UAV 33 to attach. Upon so doing, by lifting on the eyelet 60, the end 58 can be pulled to cause the remainder 57 to break the seal formed by the silicon seal 61 and remove the test cap 54. It is contemplated that instead of the eyelet 60, it could be the end 58 attaches in another part of the test cap 54 or wire 56 to provide a means for attachment of the hook 34. While the present invention has been illustrated by a description of one or more embodiments and while these embodiments have been described in considerable detail, they are not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and method, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the scope of the general inventive concept.
