Description

Technical Field

[0001] This utility model belongs to the field of reservoir silt layer thickness measurement technology, specifically relating to a reservoir silt layer thickness measurement device. Background Technology

[0002] Sedimentation in reservoirs is a significant factor affecting reservoir capacity, water quality, and engineering safety. Sediment layer thickness measurement devices are crucial tools for monitoring reservoir sedimentation. Measurement methods primarily include acoustic measurement, mechanical sampling measurement, and optical measurement. Mechanical sampling measurement mainly involves gravity sampling to obtain columnar samples of sediment.

[0003] A utility model patent with patent authorization announcement number CN217738124U discloses a silt thickness detection device, including a height adjustment component. The bottom end of the height adjustment component is rotatably connected to a connecting buckle one, the bottom of the connecting buckle one is threadedly connected to an extension rod, the bottom end of the extension rod is threadedly connected to a connecting buckle two, and the bottom of the connecting buckle two is snapped with a sampling component, which includes a sampling rod. During the descent, due to the friction between the sliding ring and the sampling rod, the float will not rise due to the buoyancy of the water. When inserted into the silt, the float contacts the silt and provides a large buoyancy to the float, so that as the sampling rod continues to descend, the sliding ring on the float slides on the sampling rod and remains on the silt. After sampling is completed, the float marks the height of the silt.

[0004] However, existing reservoir silt layer thickness measurement devices also have certain shortcomings. Although existing reservoir silt layer thickness measurement devices use gravity sampling to sample and measure reservoir silt layers, they are very inconvenient to manually operate for sampling operations due to the influence of reservoir water level. Summary of the Invention

[0005] The purpose of this invention is to provide a device for measuring the thickness of reservoir siltation layers. This solves the problem that existing devices for measuring the thickness of reservoir siltation layers, although using gravity sampling to measure the siltation layer, are inconvenient for manual operation due to the influence of the reservoir water level.

[0006] To achieve the above objectives, this utility model provides a reservoir silt layer thickness measuring device, including a chassis. A support frame is fixedly connected to the upper end of the chassis. A servo motor is mounted on the vertical part of the support frame via a support member. A winding wheel is fixedly sleeved on the outer side of the output shaft of the servo motor. A traction line is provided on the outer side of the winding wheel. A connecting plate is fixedly connected to the vertical part on the left side of the traction line. A counterweight is fixedly connected to the upper end of the connecting plate. A lubricating sleeve is fixedly connected to the horizontal part of the support frame. The lubricating sleeve is slidably connected to the traction line. A measuring mechanism is provided at the lower end of the connecting plate.

[0007] The principle of this utility model is as follows: the output shaft is driven to rotate in the opposite direction by a servo motor, which drives the take-up wheel to rotate and unwind the traction line. Under the action of guide wheel one and guide wheel two, the traction line can be guided to ensure the stable movement of the traction line. When the take-up wheel rotates, it can rotate along the inner wall of the limit block. Under the action of the limit block, the rotation of the take-up wheel can be limited to ensure the rotational stability of the take-up wheel. Under the action of the counterweight, the connecting plate can drive the measuring mechanism to move down step by step, so that the protective cylinder contacts the surface of the reservoir silt layer for subsequent measurement and sampling.

[0008] The output shaft is driven by a waterproof motor to rotate, which in turn drives the screw to rotate. With the threaded connection, the moving plate can slide along the inner wall of the chute, causing the sampling cylinder to move downwards. This allows the sampling cylinder to perform gravity sampling of the reservoir silt layer. Under the forward rotation of the output shaft driven by the servo motor, the winding wheel can wind up the traction line, making the sampling cylinder completely exposed above the water surface. This can push the end block downwards, causing the moving disc to move, which causes the elastic rope to deform and push the columnar sample, allowing the columnar sample to detach from the sampling cylinder, facilitating unloading and measurement by operators.

[0009] The beneficial effects of this utility model are as follows: This solution, through the combined use of a servo motor, a winding wheel, and other structures, can wind up the traction line, thereby adaptively adjusting the position of the connecting plate, facilitating subsequent measurement of the reservoir silt layer thickness. The guide wheels one and two ensure the stability of the traction line's movement, and the limiting block provides auxiliary rotational limiting for the winding wheel, ensuring good rotational performance. The protective cylinder protects the sampling cylinder. With the combined use of a waterproof motor, screw, and slide, the sampling cylinder can be driven to sample the reservoir silt layer. The end block and moving disc facilitate unloading and measurement by operators.

[0010] Furthermore, a guide wheel is fixedly connected to the horizontal part of the support frame. The guide wheel contacts the traction line, and the traction line can be guided by the guide wheel.

[0011] Furthermore, a second guide wheel is fixedly connected to the vertical part of the support frame. The second guide wheel is in contact with the traction line, and the traction line can be guided by the second guide wheel.

[0012] Furthermore, a limiting block is fixedly connected to the vertical part of the support frame. The limiting block contacts the winding wheel, and the winding wheel can be rotated and limited by the setting of the limiting block.

[0013] Furthermore, the measuring mechanism includes a protective cylinder, which is fixedly connected to the lower end of the connecting plate. A sliding groove is formed on the surface of the protective cylinder. A waterproof motor is fixedly installed at the lower end of the connecting plate. A screw is fixedly connected to the output shaft of the waterproof motor. A moving plate is threadedly connected to the outer side of the screw. The moving plate is slidably connected to the sliding groove. A sampling cylinder is fixedly connected to the lower end of the moving plate. The sampling cylinder is slidably connected to the protective cylinder. An clearance groove is formed on the surface of the sampling cylinder. An end block is slidably connected to the inner wall of the clearance groove. A moving disk is slidably connected to the inner wall of the sampling cylinder. The moving disk is slidably connected to the screw and fixedly connected to the end block. Through the action of the waterproof motor, screw, and other structures, the moving plate can be driven to move the sampling cylinder for sampling and measurement of the reservoir silt layer.

[0014] Furthermore, the end block is slidably connected to the clearance groove and to the protective cylinder. The end block facilitates the movement of the movable disk.

[0015] Furthermore, an elastic rope is fixedly connected to the upper end of the end block, and the other end of the elastic rope is fixedly connected to the movable plate. The end block can be connected and used by means of the elastic rope. Attached Figure Description

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, a guide wheel 9 is fixedly connected to the horizontal part of the support frame 2. The guide wheel 9 contacts the traction line 5. The guide wheel 9 guides the traction line 5. The vertical part of the support frame 2 is fixedly connected to a guide wheel 10. The guide wheel 10 contacts the traction line 5. The guide wheel 10 guides the traction line 5. The vertical part of the support frame 2 is fixedly connected to a limit block 11. The limit block 11 contacts the winding wheel 4. The limit block 11 limits the rotation of the winding wheel 4.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a measuring mechanism 12 is provided at the lower end of the connecting plate 6. The measuring mechanism 12 includes a protective cylinder 120. The protective cylinder 120 is fixedly connected to the lower end of the connecting plate 6. A sliding groove 121 is formed on the surface of the protective cylinder 120. A waterproof motor 122 is fixedly installed at the lower end of the connecting plate 6. A screw 123 is fixedly connected to the output shaft of the waterproof motor 122. A moving plate 124 is threadedly connected to the outer side of the screw 123. The moving plate 124 is slidably connected to the sliding groove 121. A sampling cylinder 125 is fixedly connected to the lower end of the moving plate 124. The sampling cylinder 125 is slidably connected to the protective cylinder 120. The surface of the sampling cylinder 125 is provided with an avoidance groove 126. An end block 127 is slidably connected to the inner wall of the avoidance groove 126. A moving disk 128 is slidably connected to the inner wall of the sampling cylinder 125. The moving disk 128 is slidably connected to the screw 123. The moving disk 128 is fixedly connected to the end block 127. Through the action of the waterproof motor 122, the screw 123 and other structures, the moving plate 124 can be driven to move the sampling cylinder 125 to sample and measure the reservoir silt layer.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, end block 127 is slidably connected to clearance groove 126 and end block 127 is slidably connected to protective cylinder 120. The end block 127 facilitates the movement of movable disk 128. An elastic rope 129 is fixedly connected to the upper end of end block 127, and the other end of elastic rope 129 is fixedly connected to movable plate 124. The end block 127 can be connected and used through the elastic rope 129.

[0026] The specific implementation process of this utility model is as follows: The output shaft is driven to rotate in the opposite direction by the servo motor 3, so as to drive the winding wheel 4 to rotate and unwind the traction line 5. Under the action of the guide wheel 1 9 and the guide wheel 2 10, the traction line 5 can be guided to ensure the stable movement of the traction line 5. When the winding wheel 4 rotates, it can rotate along the inner wall of the limiting block 11. Under the action of the limiting block 11, the rotation of the winding wheel 4 can be limited to ensure the rotational stability of the winding wheel 4. Under the action of the counterweight block 7, the connecting plate 6 can drive the measuring mechanism 12 to move down step by step, so that the protective cylinder 120 contacts the surface of the reservoir silt layer for subsequent measurement and sampling.

[0027] The output shaft of the waterproof motor 122 is driven to rotate, which in turn drives the screw 123 to rotate. With the threaded connection, the moving plate 124 can be driven to slide along the inner wall of the slide groove 121, thereby moving the sampling cylinder 125 downward. This allows the sampling cylinder 125 to perform gravity sampling of the reservoir silt layer. Under the forward rotation of the output shaft of the servo motor 3, the winding wheel 4 can be driven to wind up the traction line 5, so that the sampling cylinder 125 is completely exposed above the water surface. This can push the end block 127 downward, thereby moving the moving disk 128. This causes the elastic rope 129 to deform and push the columnar sample, allowing the columnar sample to detach from the sampling cylinder 125, facilitating unloading and measurement by the operators.

[0028] This solution utilizes a combination of servo motor 3, winding wheel 4, and other structures to wind up the traction line 5, thereby adapting the position of the connecting plate 6 for subsequent measurement of the reservoir silt layer thickness. Guide wheels 9 and 10 ensure the stability of the traction line 5's movement, and the limiting block 11 provides auxiliary rotation limit for the winding wheel 4, ensuring good rotational performance. The protective cylinder 120 protects the sampling cylinder 125. With the combined use of waterproof motor 122, screw 123, and slide 121, the sampling cylinder 125 can be driven to sample the reservoir silt layer. The end block 127 and moving disc 128 push the sampling component, facilitating unloading and measurement by operators.
