Description

Technical Field

[0001] This utility model relates to the field of trash rack technology, and in particular to a floating self-cleaning river trash rack device. Background Technology

[0002] During river dredging, trash rack technology is widely used to intercept floating debris. Trash racks are frame structures installed before the water inlet to block aquatic plants, driftwood, and other debris carried by the water flow. Trash racks can be arranged in a straight line or a semi-circular zigzag shape in plan view, and can be upright or inclined in elevation, depending on the nature and amount of debris carried by the water flow, application requirements, and dredging methods. Trash rack technology is also used in river dredging.

[0003] When in use, existing trash racks are generally fixed at both ends to the bank of the river outlet to intercept floating debris in the river. When the river water level changes, the pulleys are manually turned to adjust the height of the trash rack.

[0004] However, existing trash racks require manual adjustment of the height by turning the pulley when the river water level changes, which cannot achieve real-time adjustment, resulting in low interception efficiency and poor performance. To address these issues, a floating self-cleaning river trash rack device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a floating self-cleaning river debris barrier device, which solves the problem in the prior art that when the river water level changes, manually rotating the pulley to adjust the height of the debris barrier is not possible in real time, resulting in low interception effect and poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a floating self-cleaning river debris barrier device, comprising a base plate, two fixed columns fixedly connected to the top of the base plate, limiting plates fixedly connected to opposite sides of the two fixed columns, a first motor fixedly connected to the top of each of the two fixed columns, a take-up reel fixedly connected to the output end of each of the two first motors, a cable provided on the outer circumference of each of the two take-up reels, a movable box fixedly connected to the bottom end of each of the two cables, a debris barrier provided on the rear side between the two movable boxes, and rotatable connections between the inner walls of the two movable boxes. The device is equipped with a second rotating shaft. Two wheels are fixedly connected to the outer rings of both second rotating shafts. A first cylinder is fixedly connected to one side of the inner wall of each of the two movable boxes. A movable plate is fixedly connected to the output end of each of the two first cylinders. Two limiting grooves are opened on the top of each of the two movable plates. A first slide rail is fixedly connected to the bottom of the inner wall of each of the two movable boxes. Two push plates are slidably connected to the inner wall of each of the two first slide rails. A limiting block is fixedly connected to the top of each of the two adjacent push plates. A liquid level sensor is provided on the front side of the right limiting plate. A cleaning component is provided on one side of the right movable box.

[0007] By adopting the above technical solution, when the river water level changes, the first motor is started to drive the take-up reel to rotate, and the cable pulls the moving box to move, thereby adjusting the position of the trash rack. When the trash rack moves to the appropriate position, the push plate engages with the square groove, thereby fixing the position of the trash rack.

[0008] As a further description of the above technical solution: the cleaning component includes a limiting box, which is fixedly connected to a movable box. A second motor is fixedly connected to the top of the outer wall of the limiting box. The output end of the second motor passes through the limiting box and is fixedly connected to a lead screw. A nut pair is threaded onto the outer ring of the lead screw. A square box is fixedly connected to one side of the nut pair. A second cylinder is fixedly connected to the top of the inner wall of the square box. A movable block is fixedly connected to the output end of the second cylinder. A movable rod is rotatably connected to one side of the movable block. A rotating rod is rotatably connected to one side of the movable rod. A first rotating shaft passes through and is fixedly connected to one side of the rotating rod. Uniformly distributed crushing teeth are fixedly connected to the outer ring of the first rotating shaft.

[0009] By adopting the above technical solution, when it is necessary to clean the trash rack, the second motor is started to drive the lead screw to rotate, thereby driving the nut pair and the square box to move. The square box adjusts the position of the first rotating shaft and the crushing teeth. The crushing teeth rotate, which can clean the dirt in the trash rack.

[0010] As a further description of the above technical solution: the inner wall of the limiting groove is slidably connected to a limiting block.

[0011] By adopting the above technical solution, the limiting groove can limit the movement of the limiting block.

[0012] As a further description of the above technical solution: square grooves are evenly distributed on the front and rear sides of the inner walls of two adjacent limiting plates, the push plate engages with the square grooves, and a movable box is slidably connected to the inner wall of the limiting plate.

[0013] By adopting the above technical solution, the push plate and the square groove can fix the position of the trash rack, improving the usage effect.

[0014] As a further description of the above technical solution: a square box is slidably connected to one side of the outer wall of the limiting box, and the square box is rotatably connected to the rotating rod.

[0015] By adopting the above technical solution, the square box can drive the rotating rod to move, and the rotating rod can drive the Z-first rotating shaft to rotate.

[0016] As a further description of the above technical solution: two straight grooves are opened on the opposite side of the two limiting plates, and wheels are rotatably connected to the inner walls of the two straight grooves.

[0017] By adopting the above technical solution, the straight groove can limit the movement of the wheels, and the wheels can reduce the friction generated when the moving box moves.

[0018] As a further description of the above technical solution: the top of the trash rack is provided with evenly distributed floating blocks.

[0019] By adopting the above technical solution, the float can drive the trash rack to float on the river surface.

[0020] As a further description of the above technical solution: a second slide rail is fixedly connected to one side of the inner wall of the square box, and a moving block is slidably connected to the inner wall of the second slide rail.

[0021] By adopting the above technical solution, the second slide rail can limit the movement of the moving block, and the moving block can drive the moving rod and the rotating rod to rotate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model provides a floating self-cleaning river debris barrier device. First, through wheels, limiting grooves, limiting blocks, and a take-up reel, the water level sensor can detect the height of the river water. The first motor is started to drive the take-up reel to rotate and adjust the length of the cable. The cable drives the moving box and the debris barrier to move, which can adjust the height of the debris barrier. When the debris barrier moves to the appropriate position, the first cylinder is started to drive the moving plate to move. Under the action of the limiting groove, the push plate moves to both sides and engages with the square groove to fix the height of the debris barrier, thereby improving the use effect.

[0024] 2. The present invention provides a floating self-cleaning river debris barrier device, which, through a crushing tooth, a second motor, and a lead screw, drives the lead screw to rotate when the second motor is started. The lead screw can drive the square box and nut pair to move, which in turn drives the first rotating shaft and the crushing tooth to move. At the same time, the second cylinder is started to drive the moving block to move. The moving block can drive the moving rod and the rotating rod to rotate. The rotating rod can drive the first rotating shaft and the crushing tooth to rotate. The crushing tooth crushes the sludge in the gap of the debris barrier, which can achieve active cleaning and improve the use effect. Attached Figure Description
