[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 This utility model discloses a water-proof ventilation duct, including a ventilation pipe 1. The ventilation pipe 1 includes a horizontal pipe 11 fixedly installed on the equipment foundation. A vertical pipe 12 is fixedly installed at the end of the horizontal pipe 11 away from the equipment foundation. A rain cap 2 is fixedly installed at the upper end of the vertical pipe 12. Several ventilation holes 3 are opened on the side of the upper end of the vertical pipe 12. The rain cap 2 is conical and covers the area where the ventilation holes 3 are located along the axial direction. An insect-proof frame 41 is installed inside the vertical pipe 12 at the position below the ventilation holes 3. The insect-proof frame 41 is a cylindrical frame, and an insect-proof net 42 is installed on the inner side of the insect-proof frame 41.

[0023] Specifically, by setting up a ventilation pipe 1 including a horizontal pipe 11 and a vertical pipe 12, the height of the ventilation hole 3 is increased, and ventilation holes 3 are set on the upper side of the ventilation pipe 1 to prevent large small animals or debris from entering. Insect-proof racks 41 and insect-proof nets 42 are set inside the ventilation pipe 1 to intercept small mosquitoes and some small debris. A rainproof cap 2 is set at the upper end of the ventilation pipe 1, and the ventilation hole 3 is located inside the rainproof cap 2 to reduce the possibility of rainwater entering.

[0024] In some feasible embodiments, the ventilation duct 1 includes a horizontal duct 11 and a vertical duct 12, forming an L-shape. The ventilation duct 1 is a circular duct made of PVC or other materials. The rain cap 2 is conical, and a circular duct can be installed at the bottom of the rain cap 2, which is inserted and fitted onto the upper end of the vertical duct 12. The insect-proof frame 41 includes circular rings at both ends, connected by a plurality of arc-shaped rods arranged in a circumferential array. The insect-proof net 42 is fixedly installed on the arc-shaped rods and the bottom circular ring. It should be understood that setting the insect-proof net 42 reduces the space for air circulation, and the denser the mesh, the greater the impact. By setting the insect-proof net 42 on the vertical duct 12 and extending the insect-proof net 42 downwards along the vertical duct 12, the size of the insect-proof net 42 is increased, thereby increasing the speed at which air flows through the insect-proof net 42.

[0025] As a specific embodiment of the leak-proof ventilation duct provided in the application, a detachable pipe 13 is inserted into the upper end of the vertical pipe 12, a rain cap 2 is fixedly installed on the detachable pipe 13, a ventilation hole 3 is opened on the side wall of the detachable pipe 13, and an insect-proof frame 41 is detachably installed at the bottom of the detachable pipe 13.

[0026] Overall, by setting up the detachable tube 13, the insect-proof frame 41 can be disassembled and cleaned.

[0027] In some feasible methods, the detachable tube 13 is a cylindrical tube, and a ring with the same outer diameter as the inner diameter of the vertical tube 12 is fixedly connected to the bottom of the detachable tube 13 so that the detachable tube 13 can be inserted into the vertical tube 12. The inner side of the ring is provided with threads, and the upper end of the insect-proof frame 41 is provided with external threads. The insect-proof frame 41 is threadedly connected to the detachable tube 13. A disc with a through hole in the center is fixedly provided at the top of the detachable tube 13. A threaded tube is fixedly connected to the inner side of the rain cap 2. The rain cap 2 is fixed to the detachable tube 13 by bolts passing through the disc and threadedly connecting the threaded tube.

[0028] As another specific embodiment of the leak-proof ventilation duct provided in the application, the ventilation duct 1 is fixedly installed with an anti-climb cover 5 below the ventilation hole 3, and the surface of the anti-climb cover 5 is a smooth surface.

[0029] It should be understood that by setting up the anti-climb cover 5, the possibility of some small animals crawling along the wall of the vertical pipe 12 into the ventilation hole 3 is reduced.

[0030] In some feasible designs, the anti-climb cover 5 is a ring fitted onto the vertical pipe 12. The cross-section of the anti-climb cover 5 is triangular, giving the overall shape of the anti-climb cover 5 a flying saucer shape, thus reducing the possibility of small animals climbing over it. The anti-climb cover 5 can be made of glass or a smooth ceramic material.

[0031] As one specific embodiment of a leak-proof ventilation duct provided in the application, an exhaust fan 6 is installed at the end of the horizontal pipe 11 near the equipment foundation.

[0032] It should be understood that by setting up the exhaust fan 6, the air circulation speed is increased when rapid heat dissipation is required.

[0033] In some feasible ways, the exhaust fan 6 can be selected as an axial flow fan.

[0034] Further, please refer to Figure 1 and Figure 2 The lower end of the vertical pipe 12 passes through the horizontal pipe 11, and a downward-opening one-way sealing plate 14 is hinged to the lower end of the vertical pipe 12.

[0035] It should be understood that by setting the one-way sealing plate 14, the lower end of the vertical pipe 12 is opened in one direction. When rainwater enters, the water flows into the lower end of the vertical pipe 12 and is discharged through the one-way sealing plate 14. Furthermore, the airflow cross section is increased or decreased when the exhaust fan 6 is ventilating, thereby increasing the exhaust speed.

[0036] In some feasible embodiments, a conical barrel is fixedly installed on the inner side of the lower end of the riser 12, and a one-way sealing plate 14 is installed at the bottom of the conical barrel. The one-way sealing plate 14 is kept closed with the conical barrel by a torsion spring. An insect-proof net 42 is installed at the lower end of the riser 12.

[0037] Furthermore, a counterweight rod is fixedly installed on the one-way sealing plate 14, and a counterweight hammer 15 is fixedly connected to the counterweight rod. The counterweight hammer 15 causes the one-way sealing plate 14 to flip up and keep the vertical pipe 12 closed.

[0038] It should be understood that by setting a counterweight 15 to maintain the closure of the conical barrel by the one-way sealing plate 14, the structure is simple and the service life is improved.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
