Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment technology, specifically to an adjustable spacing water conservancy debris barrier. Background Technology

[0002] A trash rack is a trash-blocking device installed at the inlet and outlet of a water intake or discharge structure. It uses multiple rows of racks to intercept debris such as tree branches, garbage bags, and plastic bottles carried by the water flow, and to collect the debris on one side of the trash rack to prevent it from entering the water intake or discharge channel and affecting the normal operation of equipment such as machines, gates, and valves.

[0003] The river debris barrier described in authorization announcement number CN212427022U relates to the field of water conservancy equipment technology. It includes a barrier mounting frame fixed between the two banks of a river. The length of the mounting frame is consistent with the width of the river. A movable plate is slidably connected to the mounting frame, and multiple elongated holes are provided on the movable plate. The central hole is vertically positioned, and the holes on either side of the central hole are symmetrically arranged, with the holes on both sides extending away from the central hole from the bottom to the top. The spacing between the holes at the same horizontal position is consistent, and the spacing gradually increases from bottom to top. A connecting rod is slidably connected within the elongated holes. One end of the connecting rod is connected to a barrier plate, and the end of the connecting rod away from the barrier plate is connected to a slider. A sliding rod extending along the length of the mounting frame is provided, and the slider slides left and right on the sliding rod. This invention has the effect of adjustable barrier spacing.

[0004] However, existing technologies still have shortcomings:

[0005] Although the spacing between the grid plates is adjustable in the existing technology, it requires a motor to drive the connecting rod to rotate, the connecting rod to drive the worm gear to rotate, the worm gear to drive the screw to rotate, and the sleeve to drive the movable plate to move up and down. The spacing between adjacent grid plates is adjusted by sliding the movable plate up and down. The adjustment mechanism is relatively cumbersome and not easy to maintain.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] An adjustable-spacing hydraulic trash rack, such as Figure 1 and 2 As shown, it includes a fixed frame 1, with limit plates 7 fixedly connected to the upper and lower ends of the front and rear sides of the fixed frame 1, serving as support and limit for the entire device.

[0027] like Figure 3 As shown, a fixed base 2 is fixedly connected to the upper end of the fixed frame 1. Two partitions 3 are fixedly connected to the two ends inside the fixed base 2. A power mechanism 4 is installed inside the fixed base 2. The power mechanism 4 includes a cam 41 that is rotatably inserted between the two partitions 3. A motor 42 is fixedly connected between one side of the fixed base 2 and the partition 3. The partition 3 and the fixed base 2 are sealed to waterproof the motor 42. One end of the output shaft of the motor 42 is fixedly connected to one end of the cam 41. All connections are waterproof to protect the motor 42.

[0028] A moving mechanism 5 is provided on the front side of the cam 41. The moving mechanism 5 includes sliders 51 that are evenly distributed inside the front end of the fixed base 2. A sliding column 52 is fixedly connected to the rear end of the slider 51. A limiting groove 53 is provided on the cam 41 to cooperate with the sliding column 52. The middle limiting groove 53 is vertically arranged, and several limiting grooves 53 on both sides are symmetrically inclined. The lower ends of the limiting grooves 53 on both sides are inclined towards the middle. A grid plate 54 is fixedly connected to the lower end of the slider 51. A through groove 6 is provided at the lower end of the fixed base 2 to cooperate with the grid plate 54. The grid plate 54 passes through the through groove 6 and is inserted into the middle of the fixed frame 1. Limiting rods 8 are fixedly inserted into the upper and lower sides of the front end inside the fixed base 2. The limiting rods 8 are slidably inserted into the slider 51.

[0029] In specific implementation of this utility model, such as Figure 1-6As shown, during use, the starting motor 42 drives the cam 41 to rotate, thereby causing the sliding column 52 to slide relative to each other inside the limiting groove 53. Under the limitation of the limiting groove 53, they move closer or further apart. When the sliding column 52 moves away from each other, it drives the slider 51 to move away from each other under the limitation of the limiting rod 8, thereby driving the grid plate 54 to move away from each other to adjust the spacing, so that the spacing between the grid plate 54 increases, which facilitates the passage of water when the water flow is large. When the sliding column 52 slides closer to the lower end of the limiting groove 53, it can drive the grid plate 54 to move closer together, so as to normally intercept debris in the water flow. The device has a simple structure. It only requires the motor 42 to drive the cam 41 to rotate to adjust the spacing between the grid plate 54. It is convenient to use and maintain.
