Technical Field

[0001] The utility model relates to the technical field of drainage blind ditches, in particular to an assembled drainage blind ditch. Background Art

[0002] A drainage blind ditch is an underground drainage pipeline formed by wrapping water-collecting materials in filtering materials. It is usually laid at a certain depth underground and uses the gravity to collect and drain the water in the surrounding soil. An assembled drainage blind ditch is a drainage culvert system composed of different prefabricated components in a factory. These prefabricated components can be quickly assembled at the construction site to form an underground drainage channel with efficient drainage function.

The following deficiencies exist in the above patent: currently, the water-collecting pipe can drain water. In order to prevent the water outlet holes on the water-collecting pipe from being blocked, usually a layer of grid is added on the outer surface of the water-collecting pipe to resist some small particles such as broken sand, but there will still be some caked soil stuck in the water-collecting holes of the water-collecting pipe, resulting in the blockage of the water-collecting pipe and making it difficult to quickly drain the water. Over time, it is very easy to block the entire drainage blind ditch. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the water-collecting holes on the water-collecting pipe are easily blocked during drainage in the prior art, and to propose an assembled drainage blind ditch.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An assembled drainage blind ditch includes a base and a water collecting pipe arranged inside the base. An installation plate is fixedly connected to the inner wall of the water collecting pipe. It further includes: a bearing plate fixedly connected inside the water collecting pipe, and a rotating rod is rotatably connected to the top of the bearing plate; a gear is arranged on the rotating rod, a lower pressing plate is slidably connected to the base, and a tooth groove meshing with the gear is formed on the lower pressing plate; a disc is fixedly connected to the rotating rod, a slider is eccentrically fixedly connected to the disc, a sliding frame is sleeved outside the slider, and driving plates are fixedly connected to both sides of the sliding frame; a connecting plate is fixedly connected to the bearing plate, and a guiding block is fixedly connected to one end of the connecting plate away from the bearing plate; a sliding rod is slidably connected to the installation plate, a trapezoidal block is fixedly connected to the bottom of the sliding rod, and a rubber hammer is fixedly connected to the top of the sliding rod.

[0008] Preferably, a pressing strip is arranged outside the geotextile, a support skeleton is arranged inside the water permeable layer, and water collecting holes are formed on the water collecting pipe.

[0009] Preferably, protective covers are sleeved at both ends of the water collecting pipe, a grid layer is arranged on the outer surface of the geotextile, and a pressing strip is arranged outside the grid layer.

[0010] Preferably, the gear penetrates through the rotating rod and is fixedly connected to the rotating rod. The lower pressing plate penetrates through the water collecting pipe, the water permeable layer, the geotextile, and the grid layer and is slidably connected to the water collecting pipe, the water permeable layer, the geotextile, and the grid layer.

[0011] Preferably, a cross handle is fixedly connected to the top surface of the lower pressing plate, a connecting block is fixedly connected to the surface of the lower pressing plate, and a first spring is sleeved on the surface of the lower pressing plate. Both ends of the first spring abut against the connecting block and the grid layer respectively.

[0012] Preferably, the driving plate penetrates through the guiding block and is slidably connected to the guiding block. A second spring is sleeved on the surface of the sliding rod. Both ends of the second spring abut against the trapezoidal block and the installation plate respectively.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Refer to Figures 1 - 6 , a prefabricated drainage blind ditch, which includes a base 1 and a water collecting pipe 2 arranged in the base 1. An installation plate 3 is fixedly connected to the inner wall of the water collecting pipe 2. It further includes: a bearing plate 4, fixedly connected in the water collecting pipe 2, and a rotating rod 5 is rotatably connected to the top of the bearing plate 4; a gear 6, arranged on the rotating rod 5, a lower pressing plate 7 is slidably connected to the base 1, and a tooth groove 8 meshing with the gear 6 is opened on the lower pressing plate 7; a disc 9, fixedly connected to the rotating rod 5, an eccentric slider 10 is fixedly connected to the disc 9, a sliding frame 11 is sleeved outside the slider 10, and driving plates 12 are fixedly connected to both sides of the sliding frame 11; a connecting plate 13, fixedly connected to the bearing plate 4, and a guiding block 14 is fixedly connected to one end of the connecting plate 13 away from the bearing plate 4; a sliding rod 15, slidably connected to the installation plate 3, a trapezoidal block 16 is fixedly connected to the bottom of the sliding rod 15, and a rubber hammer 17 is fixedly connected to the top of the sliding rod 15. By pressing down the lower pressing plate 7, the tooth groove 8 on the lower pressing plate 7 can be driven to mesh with the gear 6, causing the gear 6 to rotate, driving the rotating rod 5 to rotate, and then driving the disc 9 to rotate, thereby driving the slider 10 to perform eccentric sliding in the sliding frame 11. Under the limiting sliding action of the guiding block 14 on the driving plate 12, the driving plate 12 performs reciprocating linear motion to the left and right. When the driving plate 12 moves to the left, it abuts against the inclined surface of the trapezoidal block 16, driving the trapezoidal block 16, the sliding rod 15 and the rubber hammer 17 to slide upward, hitting the inner wall of the water collecting pipe 2 once, enabling the water collecting pipe 2 to vibrate, so that the mud blocks blocked in the water collecting holes 21 of the water collecting pipe 2 can vibrate and fall off, enabling the water collecting holes 21 of the water collecting pipe 2 to drain smoothly, without manual cleaning, reducing labor intensity, and helping to improve the use effect of the drainage blind ditch.

[0026] A water-permeable layer 18 is arranged on the outer surface of the water collecting pipe 2, and a geotextile 19 is sleeved outside the water-permeable layer 18. The geotextile 19 is a filament geotextile 19.

[0027] There is a pressing strip 28 arranged outside the geotextile 19, and a support framework 20 is arranged inside the permeable layer 18. Water collecting holes 21 are opened on the water collecting pipe 2. The water collecting holes 21 can guide the underground soil water sucked by the permeable layer 18 into the water collecting pipe 2. The pressing strip 28 can exert a pressure on the geotextile 19 to prevent the geotextile 19 from shaking randomly.

[0028] Both ends of the water collecting pipe 2 are sleeved with protective caps 22. A grid layer 23 is arranged on the outer surface of the geotextile 19, and a pressing strip 28 is arranged outside the grid layer 23. The protective caps 22 can be covered when the water collecting pipe 2 is not in use and removed when in use.

[0029] The gear 6 penetrates through the rotating rod 5, and the gear 6 is fixedly connected to the rotating rod 5. The lower pressing plate 7 penetrates through the water collecting pipe 2, the permeable layer 18, the geotextile 19, and the grid layer 23, and is slidably connected to the water collecting pipe 2, the permeable layer 18, the geotextile 19, and the grid layer 23.

[0030] A cross handle 24 is fixedly connected to the top surface of the lower pressing plate 7. A connecting block 25 is fixedly connected to the surface of the lower pressing plate 7. A first spring 26 is sleeved on the surface of the lower pressing plate 7. Both ends of the first spring 26 are abutted against the connecting block 25 and the grid layer 23 respectively. The cross handle 24 facilitates the operator to press down the lower pressing plate 7. When the lower pressing plate 7 is pressed down, the first spring 26 will be compressed. During use, the first spring 26 can make the lower pressing plate 7 automatically reset upward.

[0031] The driving plate 12 penetrates through the guiding block 14 and is slidably connected to the guiding block 14. A second spring 27 is sleeved on the surface of the sliding rod 15. Both ends of the second spring 27 are abutted against the trapezoidal block 16 and the mounting plate 3 respectively. When the driving plate 12 abuts against the inclined surface of the trapezoidal block 16, the trapezoidal block 16 will drive the sliding rod 15 to slide upward, and at the same time, the second spring 27 will be compressed. When the driving plate 12 slides to the right and disengages from the trapezoidal block 16, the second spring 27 can make the trapezoidal block 16 drive the sliding rod 15 to automatically reset downward.

[0032] There are two sets of the mounting plate 3, the sliding rod 15, the trapezoidal block 16, and the driving plate 12, and the two sets of the mounting plate 3, the sliding rod 15, the trapezoidal block 16, and the driving plate 12 are symmetrically arranged with the center line of the water collecting pipe 2 as the axis of symmetry. By repeatedly abutting the two driving plates 12 against the trapezoidal block 16, the two rubber hammers 17 can knock on the inner wall of the water collecting pipe 2 one up and one down, so that it continuously generates vibrations, and can make the mud blocks blocked in the water collecting holes 21 fall off more quickly.

[0033] In the present utility model, when it is necessary to dredge the water collecting holes 21 on the water collecting pipe 2 in the drainage blind ditch, by pressing down the cross handle 24, the lower pressing plate 7 is driven to slide downward, thereby driving the tooth grooves 8 on its surface to mesh with the gear 6, causing the gear 6 to rotate, driving the rotating rod 5 to rotate simultaneously. While the rotating rod 5 rotates, the disc 9 is driven to rotate. While the disc 9 rotates, the slider 10 on its surface slides within the sliding frame 11. Since the driving plate 12 can only slide linearly within the guiding block 14, the sliding frame 11 and the driving plate 12 are driven to slide left and right reciprocally. When the driving plate 12 slides leftward and abuts against the inclined surface of the trapezoidal block 16, the trapezoidal block 16 will drive the sliding rod 15 at the top to slide upward, and at the same time, the second spring 27 will be compressed, thereby driving the rubber hammer 17 at the top of the sliding rod 15 to strike the inner wall of the top of the water collecting pipe 2, causing it to vibrate. When the driving plate 12 slides rightward and abuts against the trapezoidal block 16 on the right side, the trapezoidal block 16 on the left side will automatically reset under the action of the second spring 27. By operating in this way repeatedly, the two rubber hammers 17 can strike the inner wall of the water collecting pipe 2 up and down, causing it to vibrate continuously, enabling the mud blocks in the water collecting holes 21 on the water collecting pipe 2 to vibrate and fall off, making the drainage efficiency of the water collecting pipe 2 higher, and further enabling the drainage blind ditch to achieve a better drainage effect.

[0034] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
