Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, specifically a soil and water conservation protection structure for a spoil disposal site. Background Technology

[0002] A spoil heap is a general term for the storage site selected during engineering construction for excavated earth and rock, demolished concrete, and some mixtures that cannot be used. During the rainy season, large amounts of rainwater can easily cause landslides in spoil heaps. Currently, protective devices are often installed in spoil heaps to prevent soil erosion. However, some current protective devices only block the spoil. When the rainy season arrives, large amounts of rainwater fall on the soil piles and flow down the slopes they form. At this time, the protective devices are easily overwhelmed by the large amounts of rainwater, potentially causing them to collapse. Furthermore, current protective devices cannot adjust their support angle according to the actual site conditions, thus lacking practicality. Utility Model Content

[0003] The purpose of this utility model is to provide a soil and water conservation protection structure for spoil disposal sites, so as to solve the problems that existing protection devices cannot reduce the impact of rainwater and adjust the support angle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a soil and water conservation protection structure for a spoil heap, comprising a retaining plate, a bearing plate rotatably connected to the lower end of the retaining plate, a support column provided between the retaining plate and the bearing plate, the upper end of the support column rotatably connected to the retaining plate, a push rod assembly provided at the lower end of the support column, a filter inlet provided on the retaining plate, a filter screen installed inside the filter inlet, a guide rail fixedly connected to the retaining plate, the guide rail symmetrically installed at both ends of the filter screen, movable strips slidably connected to the guide rail, a baffle fixedly connected between two movable strips, a first rack installed on the side end of one baffle, a drive motor installed on the retaining plate, a first gear provided at the output end of the drive motor, the first gear meshing with the first rack.

[0005] With the above structural design, the drive motor drives the first gear to rotate, which in turn drives the first rack meshing with the first gear to move up and down. Through the cooperation of the filter screen and the baffle, this device can discharge rainwater from the slag heap during rainfall, reduce the pressure on the baffle plate, and ensure the stability of the slag heap.

[0006] Preferably, the push rod assembly includes a guide frame symmetrically fixedly connected to the upper end of the bearing plate and a movable block slidably connected inside the guide frame. The movable block is rotatably connected to the lower end of the support column. A groove is provided on the bearing plate, and a rotating rod is rotatably connected in the groove. A second gear is sleeved on the rotating rod. A second rack is provided at the lower end of the movable block, and the second gear meshes with the second rack.

[0007] By adopting the above design scheme, the second gear is rotated to drive the second rack and the moving block that mesh with it to move along the length of the guide frame, thereby changing the angle between the retaining plate and the bearing plate, making the device applicable to different protection scenarios and increasing the applicability of the device.

[0008] Preferably, a rotary motor is mounted on the support plate, and a drive bevel gear is provided at the output end of the rotary motor. A driven bevel gear is sleeved at one end of the rotating rod, and the drive bevel gear meshes with the driven bevel gear.

[0009] The above design scheme uses a rotating motor to drive the active bevel gear to rotate, which in turn drives the driven bevel gear and the rotating rod to rotate.

[0010] Preferably, a positioning cone passes through the support plate.

[0011] By adopting the above structural design, the bearing plate is fixed to the ground by the positioning cone, which increases the stability of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The drive motor drives the first gear to rotate, which in turn drives the first rack meshing with the first gear to move up and down. Through the cooperation of the filter screen and the baffle, rainwater in the slag pile can be discharged from the filter screen during rainfall, reducing the pressure on the baffle and ensuring the stability of the slag pile.

[0014] 2. By rotating the second gear, the second rack and the moving block that mesh with it move along the length of the guide frame, thereby changing the angle between the retaining plate and the bearing plate, making the device suitable for different protection scenarios and increasing the applicability of the device.

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.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a soil and water conservation protection structure for a spoil heap, including a retaining plate 1, a bearing plate 2 rotatably connected to the lower end of the retaining plate 1, two support columns 3 arranged between the retaining plate 1 and the bearing plate 2, the upper end of the support column 3 rotatably connected to the retaining plate 1, a push rod assembly 4 arranged at the lower end of the support column 3, a filter inlet on the retaining plate 1, a filter screen 5 installed in the filter inlet, and a guide rail 8 fixedly connected to the retaining plate 1. The guide rails 8 are symmetrically installed at both ends of the filter screen 5. Movable bars 12 are slidably connected to the guide rails 8, and baffles 6 are fixedly connected between the two movable bars 12. The size of the baffles 6 is larger than the size of the filter outlet. A first rack 9 is installed on the side end of one of the baffles 6. A fixed frame is installed on the retaining plate 1, and a drive motor 11 is installed on the fixed frame. The output end of the drive motor 11 passes through the fixed frame and is fitted with a first gear 10, which meshes with the first rack 9. The drive motor 11 drives the first gear 10 to rotate, causing the first rack 9 meshing with the first gear 10 to move up and down. Through the cooperation of the filter screen 5 and the baffles 6, rainwater in the slag pile can be discharged from the filter screen 5 during rainfall, reducing the pressure on the retaining plate 1 and ensuring the stability of the slag pile.

[0020] The push rod assembly 4 includes a guide frame 401 symmetrically fixedly connected to the upper end of the bearing plate 2, and a moving block 402 slidably connected inside the guide frame 401.

A second gear 404 is sleeved on the rotating rod 405. A second rack 403 is provided at the lower end of the moving block 402, and the second gear 404 meshes with the second rack 403. By rotating the second gear 404, the meshing second rack 403 and the moving block 402 move along the length of the guide frame 401, thereby changing the angle between the retaining plate 1 and the bearing plate 2. This allows the device to be used in different protection scenarios, increasing its applicability.

[0021] A rotary motor 13 is mounted on the support plate 2. The output end of the rotary motor 13 is provided with a drive bevel gear 14. One end of the rotating rod 405 is sleeved with a driven bevel gear 15. The drive bevel gear 14 and the driven bevel gear 15 mesh. The rotary motor 13 drives the drive bevel gear 14 to rotate, which in turn drives the driven bevel gear 15 and the rotating rod 405 to rotate.

[0022] Positioning cones 7 pass through the support plate 2. Four positioning cones 7 are positioned at the four corners of the support plate 2. The positioning cones 7 secure the support plate 2 to the ground, increasing the stability of the device.
