Description

Technical Field

[0001] This utility model relates to the field of trash rack technology, and in particular to a trash rack device for preventing siltation at culvert inlets and outlets. Background Technology

[0002] In water conservancy projects and road traffic ancillary facilities, culverts serve as crucial structures connecting upstream and downstream water bodies, facilitating flood discharge, and ensuring roadbed stability. The unobstructed flow of their inlets and outlets directly impacts the overall safety and efficiency of the project. However, during long-term operation, the inlet and outlet areas of culverts are prone to siltation and blockage due to debris such as silt, gravel, branches, and domestic waste carried by the water flow. Therefore, trash racks are used to intercept solid debris and some silt in the water flow.

[0003] However, most existing trash racks adopt a large-area grid structure, which achieves the function of blocking trash by covering most of the area at the entrance and exit of the culvert. However, such large-area trash racks occupy a lot of space during transportation, which increases the difficulty and cost of transportation. Especially in mountainous and remote areas where transportation conditions are limited, their transportation convenience is poor. To address this, we propose a trash rack device for preventing siltation at the entrance and exit of culverts. Utility Model Content

[0004] This utility model provides a culvert inlet and outlet anti-siltation debris barrier device, which solves the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A culvert inlet / outlet anti-siltation debris barrier device includes a U-shaped frame one and a U-shaped frame two. Debris barrier plates two are fixedly connected inside both the U-shaped frame one and the U-shaped frame two. Two sets of rotating components are arranged between the U-shaped frame one and the U-shaped frame two. Debris barrier plates one are slidably connected to the rear end faces of both the U-shaped frame one and the U-shaped frame two. A square sliding cavity is formed inside one side of both the U-shaped frame one and the U-shaped frame two. A limiting slide plate is slidably connected to the inner wall of the square sliding cavity. A square rod is fixedly connected to the upper end face of the limiting slide plate, penetrating the corresponding U-shaped frame one and the U-shaped frame two and slidably connected to the penetrating part. A fixing block is fixedly connected to the top of the square rod, and the fixing block is fixedly connected to the corresponding debris barrier plate one. A positioning component is provided at one end of both the U-shaped frame one and the U-shaped frame two. Multiple threaded holes are formed on one side of the square rod.

[0007] A further improvement of the present invention is that the rotating assembly includes a rotating seat fixedly connected to the first U-shaped plate, and a bending rotating block is rotatably connected inside the rotating seat, with one end of the bending rotating block fixedly connected to the second U-shaped plate.

[0008] A further improvement of the present invention is that the positioning component includes a threaded sleeve that passes through the corresponding U-shaped frame one and U-shaped frame two and is fixedly connected to the through portion, and the threaded sleeve is internally threaded with a positioning screw.

[0009] A further improvement of this utility model is that a cross-shaped rotating block is fixedly connected to one end face of the positioning screw, and the other end of the positioning screw is connected to the internal thread of the threaded hole.

[0010] A further improvement of this utility model is that both the positioning screw and the threaded sleeve are made of stainless steel, and the inner surface of the threaded hole is provided with an anti-rust coating.

[0011] A further improvement of this utility model is that: two mounting plates are fixedly connected to the front sides of both the first U-shaped frame and the second U-shaped frame, and mounting holes are provided on the surface of the mounting plates.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a culvert inlet and outlet anti-siltation trash rack device, which has the following advantages:

[0013] This utility model proposes a culvert inlet and outlet anti-siltation trash rack device. By using a positioning component, the restriction on the square rod can be released, allowing the square rod to slide into the square sliding cavity. This causes the trash rack plate to slide down to the back of the corresponding U-shaped frame one and U-shaped frame two, initially reducing the area of ​​the entire device. Then, by using a rotating component, the U-shaped frame one and U-shaped frame two can respectively drive the desired trash rack plate one to rotate and fold, further reducing the area of ​​the entire device and facilitating the transportation and handling of the entire device.

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a culvert inlet and outlet anti-siltation debris barrier device, including a U-shaped frame 5 and a U-shaped frame 10. A debris barrier plate 7 is fixedly connected inside the U-shaped frame 5 and the U-shaped frame 10. Two sets of rotating components are arranged between the U-shaped frame 5 and the U-shaped frame 10. A debris barrier plate 1 is slidably connected to the rear end face of the U-shaped frame 5 and the U-shaped frame 10. A square sliding cavity 11 is opened inside one side of the U-shaped frame 5 and the U-shaped frame 10. A limiting slide plate 12 is slidably connected to the inner wall of the square sliding cavity 11. A square rod 3 is fixedly connected to the upper end face of the limiting slide plate 12, penetrating the corresponding U-shaped frame 5 and the U-shaped frame 10 and slidably connected to the penetrating part. A fixing block 2 is fixedly connected to the top of the square rod 3. The fixing block 2 is fixedly connected to the corresponding debris barrier plate 1. A positioning component 4 is provided at one end of the U-shaped frame 5 and the U-shaped frame 10. A plurality of threaded holes 13 are opened on one side of the square rod 3.

[0027] Specifically, when the entire device needs to be transported, the positioning component 4 can release the restriction on the square rod 3, allowing the square rod 3 to slide into the square sliding cavity 11. At this time, the trash rack plate 1 will slide down to the back of the U-shaped frame 5 and the second U-shaped frame 10, initially shortening the area of ​​the entire device. Then, the rotating component can cause the U-shaped frame 5 and the second U-shaped frame 10 to drive the corresponding trash rack plate 1 to rotate and fold, further shortening the area of ​​the entire device and facilitating its transport. In use, the rotating component causes the U-shaped frame 5 and the second U-shaped frame 10 to drive the corresponding trash rack plate 1 to rotate and unfold. Then, under the action of the square rod 3, the trash rack plate 1 slides upward, so that the top of the trash rack plate 1 is against the top of the culvert inlet and outlet. Then, the positioning component 4 limits the square rod 3, thus keeping the trash rack plate 1 in the state where the top is against the top of the culvert inlet and outlet.

[0028] In this embodiment, the rotating assembly includes a rotating seat 8 fixedly connected to the U-shaped frame 5, and a bending rotating block 9 is rotatably connected inside the rotating seat 8. One end of the bending rotating block 9 is fixedly connected to the U-shaped frame 10.

[0029] Specifically, by cooperating with the bending block 9 and the rotating seat 8, the U-shaped frame 15 and the U-shaped frame 20 can be rotated and folded, thereby shortening the area of ​​the entire device.

[0030] In this embodiment, the positioning component 4 includes a threaded sleeve 43 that passes through the corresponding U-shaped frame 5 and U-shaped frame 10 and is fixedly connected to the through portion. The threaded sleeve 43 is internally threaded with a positioning screw 42. One end face of the positioning screw 42 is fixedly connected with a cross-shaped rotating block 41, and the other end of the positioning screw 42 is internally threaded with the threaded hole 13.

[0031] Specifically, the positioning screw 42 can be rotated by the cross-shaped rotating block 41 under the action of the threaded sleeve 43, so that the positioning screw 42 can be screwed into or out of the threaded hole 13. When the positioning screw 42 is screwed into the threaded hole 13, it will limit the square rod 3. When the positioning screw 42 is screwed out of the threaded hole 13, it will release the limit on the square rod 3.

[0032] In this embodiment, the positioning screw 42 and the threaded sleeve 43 are both made of stainless steel. The inner surface of the threaded hole 13 is provided with an anti-rust coating. The front sides of the U-shaped frame 1 5 and the U-shaped frame 2 10 are both fixedly connected to two mounting plates 6, and the surface of the mounting plate 6 is provided with mounting holes.

[0033] Specifically, the U-shaped frame 5 and the U-shaped frame 10 can be installed on the inner wall of the culvert entrance and exit for use through the mounting plate 6 and the mounting holes.

[0034] The specific working principle and usage method of this utility model are as follows:

[0035] This utility model provides a culvert inlet / outlet anti-siltation debris barrier device, such as... Figure 1-4 As shown, during use, when the entire device needs to be transported, the positioning screw 42 is rotated by the cross-shaped rotating block 41, causing the positioning screw 42 to unscrew from the threaded hole 13, releasing the restriction on the square rod 3, and allowing the square rod 3 to slide into the square sliding cavity 11. At this time, the first trash rack plate 1 will slide down to the back of the U-shaped frame 5 and the second U-shaped frame 10, initially shortening the area of ​​the entire device. Then, under the action of the rotating seat 8 and the bending rotating block 9, the U-shaped frame 5 and the second U-shaped frame 10 respectively drive the corresponding trash rack plate 1 to rotate and fold, further shortening the area of ​​the entire device and facilitating the transportation of the entire device;

[0036] In use, the rotating seat 8 and the bending rotating block 9 cause the U-shaped frame 5 and the U-shaped frame 10 to rotate and unfold the corresponding trash rack 1. Then, the square rod 3 causes the trash rack 1 to slide upward, so that the top of the trash rack 1 is against the top of the culvert inlet and outlet. Then, the cross-shaped rotating block 41 rotates the positioning screw 42 to screw the positioning screw 42 into the threaded hole 13, thereby limiting the square rod 3, so that the trash rack 1 is kept in the state of being against the top of the culvert inlet and outlet.
