Description

Technical Field

[0001] The utility model relates to the technical field of siphon drainage collection, in particular to a guide pipe. Background Art

[0002] The siphon drainage collection system is composed of polymer special-shaped sheets, siphon drainage pipes, breathable observation wells and water storage modules. It is a system with multiple functions of protection, drainage and collection. Compared with the traditional drainage collection system, it adds a breathable observation pipe to make the system breathable without air blocking water. The system can use the siphon pipe to achieve gravity drainage and siphon drainage alternately to speed up the water flow. It has many advantages such as simplified structural hierarchy, fast installation and construction speed, low overall cost and easy maintenance. The guide pipe is used in many places in the garage roof siphon drainage collection system.

[0003] According to patent number CN 213329363 U, a guide pipe for a garage roof siphon drainage collection system includes a guide pipe body, a mounting base, a waist clamp convex ring, abutting top surface, arc side surface, filter screen and other components. By arranging a mounting base at the bottom of the guide pipe body and a waist clamp convex ring at the top of the guide pipe body, the stability of the guide pipe body after installation is enhanced, and the intercepted impurities such as sand and gravel, aquatic plants, etc. can be filtered through the filter screen. However, when the existing guide pipe is in use, the filter screen is easily blocked due to excessive filtering of impurities such as sand and gravel, aquatic plants, etc., and it needs to be cleaned frequently, thereby affecting the use; and when cleaning the impurities at the filtering part of the existing guide pipe, the filter screen needs to be disassembled for cleaning, and the operation is cumbersome. For this reason, we propose a guide pipe. Utility Model Content

[0024] The top of the filter screen 2 is symmetrically fixedly connected with a fixing rod 4, and the end of the fixing rod 4 is fixedly connected with a fixing ring 5, the bottom of the fixing ring 5 is in contact with the top of the tube body 1, the end of the branch pipe 3 is connected with a blocking cover 10, and the blocking cover 10 is rotatably connected with a rotating rod 11, the end of the rotating rod 11 is located above the filter screen 2, and the outer side of the rotating rod 11 is connected with a spiral blade 12.

[0025] When the filter screen 2 is blocked during long-term use, the fixing card rod 9 can be rotated to disconnect it from the fixing card slot 8, and then the fixing ring 5 on the top of the fixing rod 4 can be clamped to the top of the tube body 1.

[0026] The top of the filter screen 2 is set as an inclined surface, and the branch pipe 3 is set inclinedly, and the inclination of the branch pipe 3 is the same as the inclination of the top of the filter screen 2.

[0027] It should be noted that the top of the filter screen 2 and the branch pipe 3 are tilted so that impurities can fall into the branch pipe 3 under the action of gravity, thereby reducing the weight borne by the filter screen 2, making it less likely to be blocked and achieving a long-term filtering effect.

[0028] An annular groove is formed at the bottom of the fixing ring 5 , and the top end of the tube body 1 is clamped in the annular groove at the bottom of the fixing ring 5 .

[0029] It should be noted that the annular groove at the bottom of the fixing ring 5 is connected with the top of the tube body 1, so that the filter screen 2 can be easily installed and removed. During long-term use, if the filter screen 2 is blocked, the fixing clamping rod 9 can be rotated to disconnect it from the fixing clamping groove 8, and then the fixing ring 5 can be directly pulled to take out the filter screen 2 for cleaning.

[0030] A connecting block 6 is symmetrically provided on the outer side of the fixing ring 5 , and a fixing clamping rod 9 is rotatably connected inside the connecting block 6 . A fixing clamping groove 8 is symmetrically provided on the outer side of the convex ring 7 , and the end of the fixing clamping rod 9 is clamped in the fixing clamping groove 8 .

[0033] It should be noted that by rotating the rotating disk 13 to rotate the rotating rod 11, the impurities on the filter screen 2 are transported to the inside of the branch pipe 3 under the action of the spiral blade 12. It is only necessary to open the blocking cover 10 and remove the impurities during the process of removing the blocking cover 10.

[0034] The height of the filter screen 2 at one end of the branch pipe 3 is lower than the height of the end of the filter screen 2 away from the branch pipe 3 , and the height of the branch pipe 3 at one end of the pipe body 1 is the same as the height of the lower end surface of the filter screen 2 .

[0035] It should be noted that impurities are filtered out by the filter screen 2, and the top surface of the filter screen 2 and the bottom end of the inner wall of the branch pipe 3 are in the same inclined plane. Under the impact of water, the impurities on the filter screen 2 can be collected inside the branch pipe 3 under the action of gravity.
