Description

Technical Field

[0001] This utility model relates to the technical field of concealed pipe joint structure, specifically a detachable large-pore flow concealed pipe joint structure. Background Technology

[0002] Pore ​​flow underground pipes allow excess water in the soil to seep into the pipe through the joints and drain away, thus controlling the groundwater level, regulating soil moisture, and improving soil physical and chemical properties. Underground pipe drainage has the advantages of facilitating mechanized field operations, saving land, and improving land utilization. The key to underground pipe drainage technology is to utilize the joints in the pipe wall to allow water to seep in and out smoothly. This technology can not only effectively control the groundwater level but also regulate soil moisture and further improve the physical and chemical properties of the soil. However, the existing joint structure does not have a detachable structure and does not have a backflow prevention structure. When the water level downstream of the drainage outlet rises sharply, it may cause backflow and flood the drainage area. In view of the above problems, in-depth research was conducted, resulting in this case. Utility Model Content

[0003] The purpose of this invention is to provide a detachable large-pore flow underground pipe connector structure to solve the problem mentioned in the background art that the existing detachable large-pore flow underground pipe connector structure does not have detachability and backflow prevention.

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.

[0020] Example 1: Please refer to Figures 1-4 A detachable large-pore flow concealed pipe connector structure includes a connector body 2, a positioning ring 13, and a mounting bracket 25. A first mounting groove 1 is provided below the connector body 2, and a sealing gasket 11 is installed on the inner wall of the first mounting groove 1. A concealed pipe body 12 is installed inside the first mounting groove 1. An inner pipe 4 is installed on the inner side above the connector body 2, and a second mounting groove 10 is provided inside the inner pipe 4. A drain pipe 7 is installed inside the second mounting groove 10, and a positioning ring 13 is installed on the inner wall of the drain pipe 7. 3. A perforated plate 5 is installed above the positioning ring 13. A first damper 14 is evenly installed on the inner wall above the drain pipe 7. A first return spring 15 is installed on the outer wall of one end of the first damper 14. A pull plate 16 is connected to one end of the first damper 14. A locking block 19 is connected to the inner wall of the pull plate 16. A slot 17 that cooperates with the locking block 19 is provided on the outer wall of the inner pipe 4. A sealing plug 23 is installed on the inner side below the drain pipe 7. An installation bracket 25 is installed below the sealing plug 23.

[0021] An outer tube 3 is installed at the top of the connector body 2, and an intermediate tube 8 is installed inside the outer tube 3.

[0022] A mounting base 20 is connected to the lower part of the perforated plate 5, and a filter screen 6 is installed on the inner side of the mounting base 20;

[0023] There are four pull plates 16, and the pull plates 16 are symmetrical about each other with respect to the center point of the drain pipe 7.

[0024] A magnetic block 18 is connected to one end of the card block 19 and the inner wall of the card slot 17, and the magnetic poles of opposite sides of the magnetic block 18 are different.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when using this structure, by pulling the pull plate 16 outward with a bit of force, the first damper 14 and the first return spring 15 are stretched and deformed, and the locking block 19 moves away from the slot 17. At the same time, the magnetic blocks 18 separate. Similarly, after pulling multiple pull plates 16 outward, the drain pipe 7 in the inner tube 4 can be taken out upward for disassembly. And by pulling the perforated plate 5 upward, the filter screen 6 can be taken out from the positioning ring 13 at the same time.

[0026] Example 2: A first sealing ring 9 is installed on the inner wall below the drain pipe 7, and a second sealing ring 24 is installed on the inner wall below the sealing plug 23;

[0027] A second damper 21 is installed on both inner walls below the drain pipe 7, and a second return spring 22 is installed on the outer wall above the second damper 21. The top of the second damper 21 is fixedly connected to one side of the mounting bracket 25.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, when using this structure, during water flow, the water pressure causes the sealing plug 23 to move downwards, and the water flows downwards through the through hole. The second damper 21 and the second return spring 22 are squeezed and deformed. After the water flow stops, the second damper 21 and the second return spring 22 return to their original positions, causing the sealing plug 23 to move upwards and block the through hole.

[0029] Working principle: When using this device, first insert the top of the concealed pipe body 12 into the first mounting groove 1 of the connector body 2 and seal it with the sealing gasket 11. Then, insert the drain pipe 7 into the second mounting groove 10 at the top. The perforated plate 5 and the filter screen 6 block soil particles and keep the pipe unobstructed for a long time. By setting the outer pipe 3 and the intermediate pipe 8, the soil is prevented from affecting the installation of the drain pipe 7 and the unobstructed flow of the connector body 2. Soil can enter the outer pipe 3 and the intermediate pipe 8 without affecting the installation of the drain pipe 7 or the blockage of the connector body 2.

[0030] Implementation steps for the first innovation point:

[0031] Step 1: By pulling the pull plate 16 outward with a little force, the first damper 14 and the first return spring 15 are stretched and deformed, and the locking block 19 is moved away from the slot 17. At the same time, the magnetic blocks 18 are separated. Similarly, after pulling multiple pull plates 16 outward, the drain pipe 7 in the inner tube 4 can be taken out upward for disassembly.

[0032] Step 2: Then pull the perforated plate 5 upwards to remove it from the positioning ring 13 along with the filter screen 6.

[0033] Implementation steps for the second innovation point:

[0034] Step 1: When the water is released, the water pressure causes the sealing plug 23 to move downward, the water flows out downward through the through hole, and the second damper 21 and the second return spring 22 are squeezed and deformed.

[0035] Step 2: After the water flow stops, the second damper 21 and the second return spring 22 reset, causing the sealing plug 23 to block the through hole upwards, thus preventing backflow.
