Description

Technical Field

[0001] This invention relates to the field of silt depth detection, specifically a descent device for silt depth detection. Background Technology

[0002] With the acceleration of urbanization, booming economy, and continuous expansion of population, urban rivers are facing increasingly serious pollution and siltation problems. On the one hand, rivers have long been subjected to urban sewage discharge and a large amount of silt brought by heavy rainfall during the rainy season, leading to gradual siltation of river channels and serious damage to the aquatic ecological environment. On the other hand, unreasonable water intake behavior in upstream river channels has led to a sharp reduction in downstream water volume, resulting in a decrease in water exchange capacity and self-purification capacity. A large amount of pollutants accumulate and settle into silt. This siltation phenomenon in river channels not only weakens their flood discharge capacity and increases the risk of flood disasters, but may also trigger severe floods, especially when encountering heavy rain during the flood season.

[0003] Therefore, river dredging plays a vital role in ensuring flood control safety and maintaining the aquatic ecological environment. However, the current method of manually placing a silt probe into the water to detect the depth of silt at the bottom is problematic because it is impossible to ensure the verticality of the silt probe. The probe is prone to tilting or even falling over, which not only leads to deviations in the detection data but may also produce completely erroneous values.

[0004] To address this problem, the present invention proposes a descent device for silt depth detection. Summary of the Invention

[0030] Example 1: Please refer to Figures 1 to 9 The present invention provides a technical solution: a descent device for silt depth detection, comprising: a base frame 10, a support frame 13 fixedly mounted on the base frame 10, two sets of support frames 13, the two sets of support frames 13 being located on both sides of the base frame 10 respectively, a top rod 1 fixedly mounted on the inner side of the top of the two sets of support frames 13, an extension block 15 mounted on the side of the top rod 1, a first fixed pulley 2 mounted below the top rod 1, a third fixed pulley 16 mounted below the extension block 15, and a top frame 4, a base plate 18, a carrier plate 32 and a support seat 6 mounted between the two sets of support frames 13;

[0031] The top frame 4 has an inner cavity 40 on its surface. The inner cavity 40 contains a threaded rod 42 and a moving block 41. The two ends of the threaded rod 42 are rotatably connected to the top frame 4. The moving block 41 is located on the threaded rod 42. The surface of the moving block 41 has a threaded hole. The threaded hole and the threaded rod 42 are threadedly matched. A connecting plate 39 is fixedly connected to the moving block 41. A wire ring is fixedly connected to the other end of the connecting plate 39. A rotating shaft 12 is set above the support 6. A wire take-up area 5 is set on the rotating shaft 12. A wire 3 is wound in the wire take-up area 5. A third fixed pulley 16 is set above the bottom plate 18. A touch switch 46 is set at the bottom of the sludge probe 17. The touch switch 46 is electrically connected to the first motor 29. The sludge probe 17 is set vertically.

[0032] In use, the base frame 10 and support frame 13 provide a stable support structure for the entire device, ensuring that the device will not tip over or shake during use. The top rod 1 and the extension block 15 are used to fix and support the first fixed pulley 2 and the second fixed pulley. At the same time, the extension block 15 provides an installation position for the third fixed pulley 16. One end of the wire 3 is connected to the sludge probe 17 and the other end is connected to the first motor 29. It is used to transmit the signal of the touch switch 46 at the bottom of the sludge probe 17 back to the first motor 29. The wire 3 is also an important component for realizing the descent and ascent of the sludge probe 17. The center of gravity of the sludge probe 17 is at its bottom, so that the sludge probe 17 is always vertical. At the same time, with the connection of the wire 3, the sludge probe 17 will be released vertically to the bottom of the sludge.

[0033] Example 2: Based on Example 1, one end of the wire 3 is connected to the first motor 29, and the other end of the wire 3 is fixedly connected to the sludge probe 17. A hole is opened through the surface of the wire ring, and the wire 3 passes through the wire ring. The outer wall of the wire 3 and the inner wall of the hole on the surface of the wire ring are slidably connected. The wire 3 passes through the pulley groove of the first fixed pulley 2, the pulley groove of the second fixed pulley, and the pulley groove of the third fixed pulley 16 in sequence. The third fixed pulley 16 is located outside the support frame 13. The bottom plate 18 is located below the top rod 1. Two sets of connecting plates 39 are fixed above the bottom plate 18. The two sets of connecting plates 39 are located on both sides of the surface of the bottom plate 18, and the third fixed pulley 16 is arranged between the two sets of connecting plates 39.

[0034] In use, the first, second and third fixed pulleys 16 are set so that the direction of the wire 3 is changed by the passage and sliding of the wire 3, while reducing the friction between the wire 3 and other parts of the device and protecting the wire 3.

[0035] A base 9 is provided at one lower end of the bottom frame 10, and a drive shaft 21 is provided at the other lower end of the bottom frame 10. There are two sets of base 9, which are fixed on both sides of one end of the bottom frame 10. The base 9 consists of a support rod and a base plate. The base plate is disc-shaped. The drive shaft 21 is connected to the bottom frame 10 through bearings. Both ends of the drive shaft 21 extend towards both sides of the bottom frame 10. Both ends of the drive shaft 21 are movably connected to a moving wheel 11. A push handle 7 is fixed on the surface of the support frame 13. The push handle 7 is located on one side of the base 9. The cross-section of the push handle 7 is "7" shaped. A rubber ring is fixed on the surface of the end of the push handle 7.

[0036] When in use, the operator holds the push handle 7 and applies force to lift it, causing the base 9 to detach from the support surface, while the moving wheel 11 always contacts the support surface, making it easy to move the device. At the same time, the bottom of the base 9 is disc-shaped, which can increase the contact area with the support surface and improve the overall stability of the device.

[0037] Example 3: Based on Example 2, an inner support frame 34 is fixed to the inner side of the two sets of support frames 13. An inclined support frame 36 is connected to the bottom of both sides of the inner support frame 34. One end of the inclined support frame 36 is fixedly connected to the inner support frame 34, and the other end of the inclined support frame 36 is fixedly connected to the inner wall of the support frame 13 by bolts. The support seat 6 is located above the inclined support frame. Both ends of the support seat 6 are fixedly connected to the inclined support frame 36 by bolts. Side plates 27 are fixed on both sides of the upper surface of the support seat 6. The rotating shaft 12 is located inside the two sets of side plates 27. Both ends of the rotating shaft 12 are rotatably connected to the two sets of side plates 27. One end of the rotating shaft 12 extends out of the side plate 27 and a driven sprocket 25 is fixed at its end face.

[0038] The carrier plate 32 is located above the bottom frame 10. Both ends of the carrier plate 32 are fixedly connected to the bottom frame 10 by bolts. A first motor 29 is provided on the carrier plate 32. A base 9 is provided at the bottom of the first motor 29. The base 9 is fixedly connected to the carrier plate 32 by bolts. A drive sprocket 23 is fixed at the output end of the first motor 29. The drive sprocket 23 is located directly below the driven sprocket 25. The drive sprocket 23 and the driven sprocket 25 are connected by a chain 24.

[0039] In use, starting the first motor 29 will drive the drive sprocket 23 to rotate. Under the transmission action of the chain 24, the driven sprocket 25 and the rotating shaft 12 will rotate, thereby realizing the operation of storing and releasing the wire 3.

[0040] Back plates 37 are fixed at both ends of the back of the top frame 4. The top frame 4 is located inside the two sets of support frames 13 and above the rotating shaft 12. The surface of the back plate 37 contacts and abuts against the inner wall of the support frame 13. The back plate 37 is fixedly connected to the support frame 13 by bolts. One end of the threaded rod 42 extends out of the top frame 4. A second motor 26 is provided on the side of the top frame 4. The output end of the second motor 26 is fixedly connected to the threaded rod 42. Slider blocks 43 are provided on both sides of the moving block 41. The sliders 43 are square plates. Slide grooves 45 are opened on both sides of the inner wall of the inner cavity 40. The sliders 43 are located in the slide grooves 45. The outer wall of the sliders 43 and the inner wall of the slide grooves 45 are slidably connected.

[0041] When in use, the starting of the second motor 26 will drive the threaded rod 42 to rotate, so that the moving block 41 moves in the inner cavity 40, which in turn drives the wire ring to move. This allows the wire 3 to be adjusted to the position of the winding area 5 when it is being stored, ensuring the stability of the wire 3. At the same time, when releasing the wire 3, it can provide guidance and support for the direction of the wire 3, ensuring the stable connection between the wire 3 and the first fixed pulley 2, thus improving the stability and manageability of the wire 3.

[0042] Example 4: Based on Example 3, guide posts 35 are fixed at both ends of the surface of the inner support frame 34. The top end face of the guide post is rounded. There are two sets of guide posts 35. Two sets of guide holes 28 are opened at both ends of the surface of the support 6. The two sets of guide holes 28 are symmetrically distributed about the central axis of the surface of the support 6. The two sets of guide holes 28 are located in the middle of the mounting holes on the surface of the support 6. The outer wall of the guide post 35 and the inner wall of the guide hole 28 are slidably connected. Vertical plates 33 are fixed on both sides of the surface of the carrier plate 32. The upper ends of the vertical plates 33 are rounded. Guide grooves 31 are opened on both sides of the surface of the seat plate 30. The guide grooves 31 are located in the middle of the mounting holes on the surface of the seat plate 30. The outer wall of the guide plate and the inner wall of the guide groove 31 are slidably connected.

[0043] In use, when connecting the support 6 and the inner support frame 34, the guide post 35 is first inserted into the guide groove 31 to limit the support 6, facilitating the subsequent installation of bolts and ensuring the stability of the rotating shaft 12 and the driven sprocket 25. Similarly, when connecting the base plate 30 and the carrier plate 32, the upright plate 33 is first inserted into the guide groove 31 to limit the base plate 30, facilitating the subsequent installation of bolts and ensuring the stability of the drive sprocket 23. This ensures the stable operation of the chain 24 transmission and the stable operation of the wire 3 winding and unwinding. Through the transmission of the sprocket and the chain 24, the rotation can be continuously and stably transmitted.

[0044] Working principle: In actual use, the take-up area 5 on the rotating shaft 12 is used to wind the wire 3. The wire 3 is connected to the silt probe 17. A touch switch 46 is installed at the bottom of the silt probe 17. When the bottom of the probe touches the mud at the bottom of the water, its own weight will press down the touch switch 46. This action will immediately stop the operation of the first motor 29, thereby automatically adjusting the length of the wire 3 to prevent the silt probe 17 from tilting or even falling over due to the wire 3 being too long. In addition, a top frame 4 is installed above the rotating shaft 12. The top frame 4 is equipped with a threaded rod 42, a second motor 26, a wire ring, a stop plate, and a moving rod. The moving block 41, along with the first, second, and third fixed pulleys 16, are designed to organize and wind the wire 3 while enhancing the vertical stability of the silt probe 17. This prevents the wire 3 from bending and obstructing water flow, ensuring that the silt probe 17 remains vertical, thereby improving the accuracy of silt depth measurement. This avoids the current practice of manually placing the silt probe 17 into the water to detect the silt depth at the bottom. Because the verticality of the silt probe 17 cannot be guaranteed, the probe is prone to tilting or even tipping over. This not only leads to deviations in the detection data but may also produce completely erroneous values.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
