Description

Technical Field

[0001] This utility model relates to the technical field of channel drainage systems, and more specifically to a detachable drainer for water conveyance channels. Background Technology

[0002] In long-distance inter-basin water transfer projects or large irrigation areas, to save costs, water conveyance channels are mostly excavated with trapezoidal cross-sections. To reduce water seepage and loss within the channels, concrete slabs are often used to line the entire channel. In sections with high groundwater levels, the groundwater level on the outer slope of the channel is higher than the water level inside the channel. This water level difference creates significant uplift pressure on the concrete lining slabs, causing them to arch and damage. Therefore, to ensure the safety of the channel lining, a channel drainage and pressure-reducing system must be installed. Currently, fixed drainers are often installed at the toe of the inner slope of the channel to address the problem of uplift damage.

[0003] The working principle of a fixed drain is as follows: when the groundwater level on the channel slope is higher than the water level in the channel, the groundwater enters the drain under gravity and forces open the check valve to flow into the channel. Conversely, when the water level in the channel is higher than the groundwater level on the channel slope, the water in the channel flows backward into the drain and impacts the check valve. The check valve automatically closes under its own weight and water pressure, preventing water flow. However, fixed drains currently have the following problems: after prolonged use, sediment gradually accumulates inside the drain, which may cause blockage and failure. Since fixed drains are a single unit, they cannot be disassembled once installed, making it difficult to clean the accumulated sediment and replace damaged internal parts.

[0004] Therefore, how to provide a drain that is easy to disassemble, allows for the cleaning of accumulated silt and sand, and enables the replacement of internal parts is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a detachable drainer for water conveyance channels, which solves the technical problem that existing fixed drainers cannot be disassembled after installation, making it difficult to clean the internal silt and replace internal parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detachable drainer for a water conveyance channel, wherein a lining plate is laid on the channel slope, and the device includes a fixed outer cylinder, a partition plate, a filter cylinder, and a water conveyance inner cylinder. The fixed outer cylinder is horizontally arranged and passes through and is fixed to the lining plate at the bottom of the channel slope. Its first end is located inside the water conveyance channel, and its second end is closed and has a water inlet hole. The second end is inserted into the channel slope to guide groundwater from the channel slope into the water conveyance channel. The partition plate is located inside the fixed outer cylinder, and its peripheral end is fixedly connected to the inner wall of the fixed outer cylinder to divide the cylinder cavity of the fixed outer cylinder into a filter cavity and a water conveyance cylinder installation cavity. The filter chamber is arranged on the side away from the water conveying channel, and an assembly hole is provided at the center of the partition plate. The filter cylinder is slidably inserted into the assembly hole, with one end closed and placed in the filter chamber, and the other end placed in the water conveying cylinder mounting cavity and extending radially outward to form an annular limiting plate. A water passage hole is provided on the filter cylinder. The inner water conveying cylinder is axially arranged in the water conveying cylinder mounting cavity. Its first end is detachably connected to the partition plate to correspondingly connect with the filter cylinder, and the annular limiting plate is pressed on the partition plate by a clamping member. A check valve is detachably installed at the second end to allow water to flow in one direction.

[0008] As can be seen from the above technical solution, compared with the existing technical solutions, this utility model discloses a detachable drainer for water conveyance channels. The inner water conveyance cylinder can be disassembled from the fixed outer cylinder to clean the accumulated silt inside. After the inner water conveyance cylinder is disassembled, the clamping component connected to it no longer presses the annular limiting plate of the filter cylinder against the partition plate, thus allowing the filter cylinder to be removed for maintenance or replacement. When the check valve is damaged, it can be disassembled for repair or replacement. This utility model's detachable drainer for water conveyance channels has a simple structure, reasonable design, and is easy to disassemble. It allows for the cleaning of accumulated silt inside and the disassembly of internal parts for repair or replacement.

[0009] Preferably, a connecting sleeve is vertically fixed on the side of the partition plate near the water conveyance channel. The inner wall of the connecting sleeve is machined with an internal thread, and the outer wall of the water conveyance inner cylinder is machined with an external thread. The connecting sleeve is threadedly connected to the water conveyance inner cylinder.

[0010] The beneficial effect of adopting the above technical solution is that the inner cylinder of the water conveyance can be quickly removed from the partition plate.

[0011] Preferably, the clamping component is a pipe body, which is axially arranged in the water delivery inner cylinder. One end of the pipe body is fixed to the inner wall of the water delivery inner cylinder through a connecting ring, and the other end can follow the movement of the water delivery inner cylinder to press the annular limiting plate against the partition plate.

[0012] The beneficial effect of adopting the above technical solution is that when the water delivery inner cylinder is screwed into the connecting sleeve, the clamping part can press the annular limiting plate onto the partition plate as the water delivery inner cylinder moves, so that the filter cylinder no longer moves; after the water delivery inner cylinder is screwed out from the connecting sleeve, the clamping part no longer presses the annular limiting plate, and the filter cylinder can be taken out from the fixed outer cylinder for maintenance or replacement.

[0013] Preferably, the wall of the mounting hole on the partition plate extends toward the water conveyance channel to form a boss, and the boss can perpendicularly abut against the side surface of the annular limiting plate.

[0014] The beneficial effect of adopting the above technical solution is that the boss and the clamping member can respectively abut against the two side plates of the annular limiting plate, and clamp the annular limiting plate between the two.

[0015] Preferably, a detachable drainer for a water conveyance channel further includes an end cap, which is a cylindrical body. One end of the end cap is detachably connected to the first end of the fixed outer cylinder, and the other end is fixed with a sealing plate. The sealing plate has a drain hole.

[0016] Preferably, geotextile is fixed on the outer wall of the filter cylinder and on the inner surface of the sealing plate.

[0017] The beneficial effect of adopting the above technical solution is that geotextile can restrict large particles of sand and gravel from entering the filter cylinder and the inner water conveyance cylinder from the outside.

[0018] Preferably, the filter cartridge is made of stainless steel filter mesh.

[0019] Preferably, the fixed outer cylinder, end cap, and water-carrying inner cylinder are all made of rigid polyvinyl chloride material.

[0020] The beneficial effects of adopting the above technical solution are that the fixed outer cylinder, end cap and water conveying inner cylinder made of rigid polyvinyl chloride material have high hardness, strong corrosion resistance and are not easily damaged.

[0021] Preferably, the fixed outer cylinder is 150mm long and has an inner diameter of 100mm. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] See appendix Figures 1 to 8 This utility model discloses a detachable drainer for a water conveyance channel. The channel slope is paved with a lining plate 100, and the device includes a fixed outer cylinder 1, a partition plate 2, a filter cylinder 3, and a water conveyance inner cylinder 4. The fixed outer cylinder 1 is horizontally arranged and fixed to the lining plate 100 at the bottom of the channel slope. Its first end is located inside the water conveyance channel, and its second end is closed with an inlet hole 10. The second end is inserted into the channel slope to guide groundwater from the slope into the water conveyance channel. The partition plate 2 is located inside the fixed outer cylinder 1, and its peripheral end is fixedly connected to the inner wall of the fixed outer cylinder 1 to divide the cavity of the fixed outer cylinder 1 into a filter chamber 11 and a water conveyance cylinder. The mounting cavity 12 and the filter cavity 11 are arranged on the side away from the water conveying channel. The partition plate 2 has an assembly hole at its center. The filter cylinder 3 is slidably inserted into the assembly hole. One end of the filter cylinder is closed and placed in the filter cavity 11, and the other end is placed in the water conveying cylinder mounting cavity 12 and extends radially outward to form an annular limiting plate 31. The filter cylinder 3 has a water passage hole 30. The water conveying inner cylinder 4 is axially arranged in the water conveying cylinder mounting cavity 12. Its first end is detachably connected to the partition plate 2 to connect with the filter cylinder 3. The annular limiting plate 31 is pressed onto the partition plate 2 by the clamping member 5. The second end is detachably installed with a check valve 6 to allow water to flow in one direction.

[0036] Specifically, filter cartridge 3 is made of stainless steel filter mesh.

[0037] Specifically, the fixed outer cylinder 1 is 150mm long and has an inner diameter of 100mm.

[0038] When the groundwater level 201 in the channel slope is higher than the water level 202 in the channel or when there is no water in the channel, the groundwater in the channel slope enters the channel through this device, reducing the uplift pressure damage to the lining plate 100 caused by the water level difference; when the water level 202 in the channel is higher than the groundwater level 201 in the channel slope, the water in the channel impacts the check valve 6, and the check valve 6 automatically closes under the action of gravity and water pressure, preventing water in the water conveyance channel from flowing into the channel slope and reducing the water loss during water conveyance.

[0039] In some specific examples, a connecting sleeve 7 is vertically fixed on the side of the partition plate 2 near the water conveyance channel. The inner wall of the connecting sleeve 7 is machined with internal threads, and the outer wall of the water conveyance inner cylinder 4 is machined with external threads. The connecting sleeve 7 is threadedly connected to the water conveyance inner cylinder 4.

[0040] In some specific examples, the clamping element 5 is a pipe body, which is axially arranged in the water conveying inner cylinder 4. One end of the pipe body is fixed to the inner wall of the water conveying inner cylinder 4 through a connecting ring, and the other end can follow the movement of the water conveying inner cylinder 4 to press the annular limiting plate 31 onto the partition plate 2.

[0041] When the inner water cylinder 4 is threaded into the connecting sleeve 7, the clamping member 5 moves with the inner water cylinder 4 and presses the annular limiting plate 31 onto the partition plate 2, so that the filter cylinder 3 no longer moves; when the inner water cylinder 4 is unscrewed from the connecting sleeve 7, the clamping member 5 no longer presses the annular limiting plate 31, and the filter cylinder can be taken out from the fixed outer cylinder 1 for maintenance or replacement.

[0042] In some specific examples, the wall of the assembly hole extends toward the water conveyance channel to form a boss 21, which can perpendicularly abut against the side surface of the annular limiting plate 31.

[0043] In some specific examples, a detachable drainer for a water conveyance channel also includes an end cap 8, which is a cylindrical body. One end of the end cap 8 is detachably connected to the first end of the fixed outer cylinder 1, and the other end is fixed with a sealing plate 81, on which a drain hole 80 is provided.

[0044] Specifically, geotextile 9 is fixed on the outer wall of the filter cylinder 3 and on the inner side of the sealing plate 81. The geotextile 9 can restrict large particles of sand and gravel from entering the filter cylinder 3 and the water conveying inner cylinder 4 from the outside.

[0045] Specifically, the fixed outer cylinder 1, end cap 8, and water-transporting inner cylinder 4 are all made of rigid polyvinyl chloride (PVC). Rigid PVC materials give the fixed outer cylinder 1, end cap 8, and water-transporting inner cylinder 4 high hardness, strong corrosion resistance, and make them less prone to damage.

[0046] This utility model discloses a detachable drainer for water conveyance channels. The inner water conveyance cylinder is threadedly connected to the connecting sleeve on the partition plate. The inner water conveyance cylinder can be disassembled from the connecting sleeve at any time to clean the mud and sand inside. When the inner water conveyance cylinder is screwed into the connecting sleeve, the inner water conveyance cylinder can press the annular limiting plate onto the partition plate through the clamping component, thereby preventing the filter cylinder from moving. When the inner water conveyance cylinder is screwed out from the connecting sleeve, the clamping component no longer presses the annular limiting plate, and the filter cylinder can be removed from the fixed outer cylinder for maintenance or replacement.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
