Detailed Description

The present application is described in further detail below with reference to figures 1-6.

The embodiment of the application discloses deodorant device of sewer. Referring to fig. 1 and 2, deodorant device of sewer includes deodorant pipe 2 of vertical setting, and the rainwater flows into sewer 1 from deodorant pipe 2 internal, and the top of deodorant pipe 2 is outwards turned over and is formed with butt limit 21, has the horizontal plane that is used for placing the sewer apron in the sewer 1, butt limit 21 and the horizontal plane butt in the sewer 1. But be equipped with the seal structure that opens and shuts automatically in the deodorant pipe 2, seal structure is including being fixed in deodorant pipe 2 in and the uide bushing 3 of vertical setting, the uide bushing 3 endotheca is equipped with guide arm 4, guide arm 4 can slide from top to bottom in uide bushing 3. The bottom of guide arm 4 is fixed with closing plate 6, and the laminating of the upper surface of closing plate 6 and the bottom of deodorant pipe 2, and the laminating department of closing plate 6 upper surface and deodorant pipe 2 is equipped with annular groove 62 that can impound. The guide rod 4 is sleeved with a return spring 43 which applies upward pretightening force to the guide rod 4.

Referring to fig. 1, when rainwater enters a sewer 1 through an odor prevention pipe 2, the rainwater accumulated on the upper surface of a sealing plate 6 reaches a certain weight, so that the sealing plate 6 moves downward, the moving sealing plate 6 drives a guide rod 4 to slide along a guide sleeve 3, and a return spring 43 sleeved on the guide rod 4 is deformed. At this time, a gap is formed between the sealing plate 6 and the deodorizing pipe 2, and the rainwater flows into the sewer 1 along the gap. After the drainage is finished, a part of rainwater can be remained in the annular groove 62, the sealing plate 6 is reset again under the elastic force of the reset spring 43 and is abutted against the bottom of the deodorization pipe 2, and the whole deodorization device is closed. And because rainwater is accumulated in the annular groove 62, even if sundries such as silt are blocked at the joint of the sealing plate 6 and the deodorization pipe 2, the sealing plate 6 and the deodorization pipe 2 cannot be completely closed, the rainwater in the annular groove 62 can form water seal at the joint of the sealing plate 6 and the deodorization pipe 2, so that the situation that the deodorization effect is poor due to the fact that a gap is formed in the deodorization device because of blocking of the sundries such as silt is reduced.

Referring to fig. 3 and 4, a cylindrical top block 41 is connected to the top of the guide rod 4 through a screw thread, a threaded hole 411 is formed in the middle of the bottom surface of the top block 41, an external thread 42 corresponding to the threaded hole 411 is arranged on the side wall of the guide rod 4 and near the top of the guide rod, and the top block 41 is connected to the guide rod 4 through a screw thread.

Referring to fig. 5, the top end of the return spring 43 abuts against the bottom surface of the top block 41, and the bottom end of the return spring 43 abuts against the top end of the guide sleeve 3.

Referring to fig. 3 and 5, the guide sleeve 3 is provided with a plurality of support plates 5 connecting the guide sleeve with the inner wall of the odor-proof pipe 2, one end of each support plate 5 is connected with the outer side wall of the guide sleeve 3, and the other end of each support plate 5 is connected with the inner wall of the odor-proof pipe 2. A plurality of backup pads 5 evenly arrange along the circumference surface of uide bushing 3, and the equal spiral slope of each backup pad 5 sets up. Wherein, the spiral incline direction of each backup pad 5 is the anticlockwise rotation from the top down, and the rainwater can anticlockwise rotation when leaking the mouth, under the more condition of rainwater, sets backup pad 5 to the anticlockwise rotation and helps the rainwater to trickle smoothly. Still the cover is equipped with filter screen 7 on the uide bushing 3, and the bottom surface of filter screen 7 and the top butt of a plurality of backup pads 5, and filter screen 7 filters great debris, reduces the circumstances that debris blockked up deodorant device.

Referring to fig. 1 and 6, the bottom end of the guide rod 4 is fixed to the middle of the upper surface of the sealing plate 6, the upper surface of the sealing plate 6 is provided with a guide protrusion 61, the upper surface of the guide protrusion 61 is provided with a spiral groove 63, and the spiral groove 63 is spirally downward from the middle of the upper surface of the sealing plate 6 and communicates with the annular groove 62. When rainwater enters the upper surface of the sealing plate 6, the flow guide bulge 61 can guide the rainwater into the annular groove 62 through the spiral groove 63, further, the spiral groove 63 plays a certain water storage role, and after water in the annular groove 62 is evaporated, the water in the spiral groove 63 can supplement water to the annular groove 62, so that the water sealing time is prolonged.

The implementation principle of the embodiment is as follows: when the rainwater gets into in the deodorant device, filter debris through filter screen 7 earlier, then the rainwater passes through spiral helicine backup pad 5, and the rainwater spiral is arranged the upper surface to closing plate 6 downwards, and after accumulating a certain amount of rainwater, the action of gravity of rainwater orders about closing plate 6 and moves down, and closing plate 6 of downward movement drives guide arm 4 and moves down and make reset spring 43 compress, and the rainwater trickles to sewer 1 in from the clearance department between closing plate 6 and deodorant pipe 2. After the drainage is completed, the return spring 43 releases elastic potential energy to drive the guide rod 4 to move upwards, and the guide rod 4 moving upwards drives the sealing plate 6 to move upwards, so that the deodorization device is closed. By utilizing the water storage function of the annular groove 62, the joint of the sealing plate 6 and the deodorization pipe 2 is sealed by water, so that the odor leakage caused by the gap between the sealing plate 6 and the deodorization pipe 2 is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
