[0002] Drainage pipes are pipeline facilities used to discharge liquids such as rainwater and sewage. They are an important part of urban infrastructure. Their working principle is mainly based on the effect of gravity, using the slope of the pipe during laying to allow the liquid to flow naturally, thereby achieving drainage.

[0003] In municipal garden drainage systems, drainage pipes are laid to create liquid flow paths to prevent flooding in municipal gardens. However, existing drainage pipes only allow liquid to flow in a single direction. To add branch lines to divert the flow, the pipes need to be cut and joints installed, which increases the workload and makes it inconvenient to install other pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a municipal garden drainage pipe that is easy to install, in order to solve the problem mentioned in the background art that when the drainage pipe is used, the liquid only flows in a single direction, and when branch lines are added to its surface to divert the flow, the pipe must be cut and joints installed, which easily increases the workload and makes it inconvenient to install other pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal garden drainage pipe that is easy to install, comprising a drainage pipe body, a connecting hole on the surface of the drainage pipe body, a connecting pipe fixedly connected to the surface of the drainage pipe body, an installation pipe connected to the surface of the connecting pipe by a thread, an annular plate fixedly connected to the inner surface of the installation pipe, a flange plate fixedly connected to the outer surface of the installation pipe, a guide ring and a first sealing ring fixedly connected to the surface of the annular plate, an installation plate abutting against the surface of the annular plate, a threaded groove on the surface of the annular plate, an insertion hole on the surface of the installation plate, bolts installed on the surface of the installation plate, a second sealing ring fixedly connected to one side of the installation plate, a fixing plate fixedly connected to the other side of the installation plate, an annular groove on the surface of the first sealing ring, a movable rod movably connected to the surface of the fixing plate, a rotating shaft fixedly connected to the surface of the fixing plate, and a rotating hole on the surface of the movable rod.

[0006] Preferably, the diameter of the connecting hole is the same as the inner diameter of the connecting pipe, the connecting pipe is abutted against the surface of the annular plate, one side of the mounting pipe is mounted on the surface of the drain pipe body, and the other side of the mounting pipe is mounted on the surface of the flange plate.

[0007] Preferably, the inner diameter of the annular plate is smaller than the inner diameter of the guide ring, the outer diameter of the guide ring is the same as the inner diameter of the connecting pipe, the outer surface of the guide ring is attached to the inner surface of the connecting pipe, the cross-section of the guide ring is a right triangle, and the diameter of the mounting plate is larger than the inner diameter of the annular plate.

[0008] Preferably, the size of the insertion hole is larger than the size of the threaded groove, the bolt is inserted into the surface of the insertion hole, one end of the bolt is threaded into the surface of the threaded groove, and the other end of the bolt is abutted against the surface of the mounting plate.

[0009] Preferably, the cross-section of the second sealing ring is "L" shaped, and the second sealing ring is engaged with the inner surface of the first sealing ring through an annular groove.

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 1-5 One embodiment provided by this utility model:

[0023] A municipal garden drainage pipe that is easy to install includes a drainage pipe body 1, a connection hole 2 on the surface of the drainage pipe body 1, a connecting pipe 3 fixedly connected to the surface of the drainage pipe body 1, an installation pipe 4 threadedly connected to the surface of the connecting pipe 3, an annular plate 5 fixedly connected to the inner surface of the installation pipe 4, a flange plate 18 fixedly connected to the outer surface of the installation pipe 4, a guide ring 6 and a first sealing ring 11 fixedly connected to the surface of the annular plate 5, an installation plate 7 abuttingly connected to the surface of the annular plate 5, a threaded groove 8 on the surface of the annular plate 5, and a insertion hole 9 on the surface of the installation plate 7. Bolts 10 are installed on the surface of the mounting plate 7. A second sealing ring 12 is fixedly connected to one side of the mounting plate 7, and a fixing plate 14 is fixedly connected to the other side of the mounting plate 7. An annular groove 13 is opened on the surface of the first sealing ring 11. A movable rod 15 is movably connected to the surface of the fixing plate 14. A rotating shaft 16 is fixedly connected to the surface of the fixing plate 14. A rotating hole 17 is opened on the surface of the movable rod 15. Rainwater, sewage and other liquids in the municipal garden can flow out from its inner surface through the drainage pipe body 1. The surfaces of other pipes are also equipped with flange plates 18, which are existing and will not be described in detail here.

[0024] Furthermore, the diameter of the connecting hole 2 is the same as the inner diameter of the connecting pipe 3. The connecting pipe 3 is abutted against the surface of the annular plate 5. One side of the mounting pipe 4 is installed on the surface of the drain pipe body 1, and the other side of the mounting pipe 4 is installed on the surface of the flange plate 18. By opening multiple sets of connecting holes 2 on the surface of the drain pipe body 1 and connecting the connecting pipe 3, the mounting pipe 4 and the flange plate 18, the drain pipe body 1 itself can have the function of adding other pipes, so as to improve the convenience of adding and avoid damage to the drain pipe body 1. The connection between the connecting pipe 3 and the mounting pipe 4 can realize the connection between the drain pipe body 1 and the flange plate 18, thereby allowing other pipes to be added to the surface of the drain pipe body 1 through the flange plate 18.

[0025] Furthermore, the inner diameter of the annular plate 5 is smaller than the inner diameter of the guide ring 6, and the outer diameter of the guide ring 6 is the same as the inner diameter of the connecting pipe 3. The outer surface of the guide ring 6 is attached to the inner surface of the connecting pipe 3. The cross-section of the guide ring 6 is a right triangle. The diameter of the mounting plate 7 is larger than the inner diameter of the annular plate 5. Under the action of the annular plate 5, the mounting plate 7 can be supported. The mounting plate 7 can act as a gate at the connecting hole 2. Under the action of the guide ring 6, it can guide the flow and prevent the liquid flowing from the connecting hole 2 into other pipes from containing impurities from getting stuck and blocking the edge of the annular plate 5.

[0026] Furthermore, the size of the insertion hole 9 is larger than the size of the threaded groove 8. The bolt 10 is inserted into the surface of the insertion hole 9. One end of the bolt 10 is threaded into the surface of the threaded groove 8, and the other end of the bolt 10 is abutted into the surface of the mounting plate 7. The bolt 10 can be installed under the action of the threaded groove 8 and the insertion hole 9. There are multiple sets of threaded grooves 8 and insertion holes 9 arranged in a ring array and distributed on the surface of the ring plate 5 and the mounting plate 7 respectively. The mounting plate 7 can be disassembled and assembled under the connection of the bolt 10, the threaded groove 8, and the insertion hole 9.

[0027] Furthermore, the cross-section of the second sealing ring 12 is "L" shaped. The second sealing ring 12 is engaged with the inner surface of the first sealing ring 11 through the annular groove 13. Both the first sealing ring 11 and the second sealing ring 12 are made of rubber, and the connection between the two can achieve the effect of sealing and preventing water seepage at the connection between the annular plate 5 and the mounting plate 7.

[0028] Furthermore, two sets of fixing plates 14 are provided, and the two sets of fixing plates 14 are installed at both ends of the movable rod 15. Each set of fixing plates 14 consists of two plates, and each set of fixing plates 14 is attached to both sides of the movable rod 15. Under the action of the two sets of fixing plates 14, the installation effect of the movable rod 15 can be achieved, thereby enabling the movable rod 15 to move on the surface of the mounting plate 7.

[0029] Furthermore, the surface of the movable rod 15 is U-shaped. The movable rod 15 is rotatably connected to the surface of the rotating shaft 16 through the rotating hole 17. Both ends of the rotating shaft 16 are fixedly connected to the surface of the fixed plate 14. The diameter of the rotating hole 17 is the same as the diameter of the rotating shaft 16. The inner diameter of the flange plate 18 is the same as the inner diameter of the mounting pipe 4. With the connection between the rotating shaft 16 and the rotating hole 17, the movable rod 15 can rotate around the rotating shaft 16 as the center.

[0030] Working principle: When adding other pipe branches to the municipal garden drainage pipe, first rotate the bolt 10 so that it moves through the threaded groove 8 and remove it to cancel the insertion effect with the insertion hole 9. Then, grasp the movable rod 15 and rotate it around the rotating shaft 16. Then, pull the movable rod 15 to the outside of the installation pipe 4 to move the installation plate 7 together and remove it from the surface of the annular plate 5. At the same time, cancel the engagement state of the second sealing ring 12 and the first sealing ring 11 to complete the opening effect at the connection hole 2. At this time, install other pipes on the surface of the flange plate 18. Then, when the drainage pipe drains, the liquid enters the connection pipe 3 through the connection hole 2 and flows into the other pipes under the guidance of the guide ring 6 through the annular plate 5.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
