[0031] See also Figure 1-4 The utility model provides a technical solution: a drainage device for a subway HVAC system, comprising an upper pipe 1, a sealing cover 2 is fixedly connected to the outer wall of the lower end of the upper pipe 1, a sealing ring 3 is bonded to the edge of the upper inner wall of the sealing cover 2, a positioning ring 4 is sleeved on the outer wall of the lower end of the upper pipe 1, and a filter cartridge 5 is fixedly connected to the outer wall of the lower end of the positioning ring 4.

[0032] A pipe head 6 is movably mounted on the inner wall of the sealing cover 2 , and a limiting mechanism 7 is arranged on the outer wall of the upper end of the side of the pipe head 6 .

[0033] The inner wall of the lower end of the pipe head 6 is installed with a middle pipe 9 through a sealed bearing, and the outer wall of the lower end of the middle pipe 9 is connected to the outer wall of the upper end of the lower pipe 11 through a hose 10. The side outer walls of the lower pipe 11 and the upper pipe 1 are respectively fixed with mounting rods 12, and the outer wall of the mounting rod 12 is sleeved with a rod sleeve 13, and the end of the rod sleeve 13 is movably connected with a mounting plate 14.

[0034] In this example, the sealing cover 2 and the tube head 6 are threadedly connected, and the tube head 6 and the sealing ring 3 are in close contact, so that the user can rotate the tube head 6 to disassemble and assemble the tube head 6, and the sealing performance of the device is improved through the sealing ring 3.

[0035] In this example, the upper tube 1 and the positioning ring 4 are threadedly arranged, and the positioning ring 4 and the sealing cover 2 are closely connected, so that the user can rotate the positioning ring 4 to disassemble and assemble the filter cartridge 5.

[0036] The limiting mechanism 7 in this example includes a limiting arm 701, a clamp 702 and a knob 703. The limiting arm 701 is movably connected to the outer wall of the tube head 6. The outer wall of one end of the limiting arm 701 is fixedly connected with the clamp 702, and the inner wall of the other end of the limiting arm 701 is movably provided with a knob 703. It is convenient to limit the tube head 6 through the limiting mechanism 7, thereby preventing the tube head 6 from loosening and making the device stable to use.

[0037] The limit arm 701 and the tube head 6 in this example form a rotating structure, and the clamp 702 and the tube head 6 are arranged in a close fit, which is convenient for the user to push the limit arm 701 to rotate around the tube head 6, so that the clamp 702 fits the tube head 6, thereby aligning the knob 703 and the sleeve 8.

[0038] In this example, a ferrule 8 is fixedly connected to the outer wall of the sealing cover 2 on the side of the knob 703. The ferrule 8 and the limiting arm 701 are respectively threadedly connected to the knob 703, so that the user can rotate the knob 703 so that the knob 703 moves relative to the limiting arm 701 and is inserted into the ferrule 8, thereby limiting the tube head 6 to prevent the tube head 6 from loosening.

[0039] The mounting rod 12 and the rod sleeve 13 in this example are threadedly arranged, so that the user can rotate the rod sleeve 13 to move the rod sleeve 13 along the mounting rod 12, thereby driving the mounting plate 14 to move so that the mounting plate 14 is attached to the wall for installation of the device.

[0040] The rod sleeve 13 and the mounting plate 14 in this example form a rotating structure, which facilitates the rod sleeve 13 to rotate relative to the mounting plate 14.

[0041] Working principle: According to Figure 1-4 As shown, the user moves the positioning ring 4 to be sleeved on the lower end of the upper tube 1, and then the user rotates the positioning ring 4 so that the positioning ring 4 fits the sealing cover 2, thereby completing the installation of the filter cartridge 5, and then the user moves the pipe head 6 to insert it into the sealing cover 2, and then the user rotates the pipe head 6 so that the pipe head 6 fits the sealing ring 3, and as the pipe head 6 moves to install, the pipe head 6 drives the hose 10 to deform, and then the user pushes the limiting arm 701 to rotate around the pipe head 6 until the clamp 702 fits the pipe head 6, and then the user rotates the knob 703, and then the knob 703 moves relative to the limiting arm 701 and is inserted into the clamping sleeve 8, thereby completing the limiting of the pipe head 6 to prevent the pipe head 6 from loosening, and then the user connects the upper tube 1 and the subway HVAC system The user then rotates the rod sleeve 13, which then moves along the mounting rod 12. Next, the rod sleeve 13 drives the mounting plate 14 to move and fit the wall. Then, the user connects the mounting plate 14 and the wall with bolts, and similarly operates the remaining rod sleeves 13 and mounting plates 14, thereby completing the installation of the device, making it easy to connect the device to the wall and improving the stability of the device. Then, when the air conditioner is draining, water flows into the device through the upper pipe 1, and then the water flows out of the upper pipe 1 and into the pipe head 6. At this time, the filter cartridge 5 filters impurities in the water, and then the water flows out of the device through the middle pipe 9, the hose 10 and the lower pipe 11, thereby completing the drainage of the subway HVAC system.
