Description

Technical Field

[0001] This utility model belongs to the field of building heating, ventilation and air conditioning technology, and specifically relates to a building heating and ventilation anti-blockage drainage device. Background Technology

[0002] In building HVAC piping, during operation, easily aggregated substances can enter the drainage pipes and accumulate under the influence of water flow, potentially causing blockages. Existing HVAC piping typically uses filters to remove these impurities, but after a period of use, the filters still need to be cleaned. Cleaning requires disassembling the piping, which, while more convenient than directly cleaning the pipes, is still time-consuming and inefficient. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a building heating and ventilation anti-blockage drainage device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this building heating and ventilation anti-blockage drainage device to solve its technical problems is as follows:

[0005] A building heating and ventilation anti-blocking drainage device is provided, comprising a square tube with a filter screen fixedly installed inside. A bend is provided on one side of the square tube, with both ends of the bend fixedly installed on the square tube and communicating with the inside of the square tube. The two ends of the bend are respectively distributed on both sides of the filter screen. A drain pipe is fixedly installed on the square tube and communicating with the square tube on the opposite side of the top of the bend. A rotating shaft is rotatably installed on the square tube, with the rotating shaft located on one side of the top of the bend and one side of the drain pipe. Gate plates are fixedly installed on the rotating shafts, and the gate plates can close the corresponding bend and drain pipe respectively. The gate plates cooperate with each other to close the square tube.

[0006] Furthermore, the output shaft of the motor is fixedly connected to one side of the rotating shaft extending out of the square tube, and the motor is fixedly mounted on the square tube.

[0007] Furthermore, each motor is equipped with a brake.

[0008] Furthermore, a limit stop bar is provided on one side of the gate.

[0009] Furthermore, valves are fixedly installed on both sides of the square tube.

[0010] Furthermore, flanges are fixedly installed on the valves respectively.

[0011] Furthermore, the filter screen is inclined inside the square tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides an example of a building heating and ventilation anti-blocking drainage device. In use, the device is connected to the heating and ventilation piping. Under normal conditions, two gates close the corresponding bends and drain pipes respectively. Water in the pipes is filtered through a filter screen. After a period of use, controlling the two rotating shafts to rotate the gates close them, blocking the middle of the square pipe. This blocks the water flow below the square pipe, causing the water in the pipes to flow backward through the bends, through the filter screen, and out through the drain pipe, thus cleaning the filter screen. After cleaning, the two rotating shafts can be reversed to re-block the bends and drain pipes, reconnecting the pipes and restoring their use. This device eliminates the need to disassemble the pipes to clean the filter screen, providing convenient and rapid cleaning.

[0014] 2. The present invention provides a building heating and ventilation anti-blocking drainage device, which allows for easy rotation of the shaft via a motor.

[0015] 3. The present invention provides a building heating and ventilation anti-blocking drainage device, which uses a brake inside the motor to lock the output shaft of the motor when the motor is off, thereby preventing the shaft from rotating and causing the gate to fail.

[0016] 4. The present invention provides a building heating and ventilation anti-blocking drainage device, which limits the maximum stroke of the gate plate by means of a limiting stop bar, thereby preventing the gate plate from rotating too much.

[0017] 5. This utility model provides a building heating and ventilation anti-blocking drainage device, which allows for convenient closure of the corresponding part of the square pipe during use via a valve.

[0018] 6. This utility model provides an example of a building heating and ventilation anti-blocking drainage device, which can be easily connected to the heating and ventilation pipes via a flange.

[0019] 7. In this utility model example, a building heating and ventilation anti-clogging drainage device has an inclined filter screen that can increase the filtration area and improve the filtration effect. Attached Figure Description
