Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a comprehensive sediment treatment device for water conservancy projects. Background Technology

[0002] my country is a vast country with abundant water resources, including numerous rivers such as the Yangtze, Yellow, and Huai Rivers. These rivers generally suffer from sediment problems. Constructing reservoirs upstream of natural rivers raises water levels and slows water flow, reducing the water's ability to carry sediment. This leads to the gradual deposition of large amounts of sediment in the reservoir area. Therefore, sediment management is crucial in water conservancy projects.

[0003] Existing water conservancy projects mostly use dredgers or sand pumps to extract sediment. However, because the location of the sand pumps is fixed, and the method of using a combination of extraction port, mixing device, and sand pump for sediment extraction has the following problems: First, sediment tends to clump together after long-term deposition and does not move with the water flow. Second, when existing mixers are mixing and breaking up the sediment, the working part of the mixer will sink, and the surrounding water will flow over. However, the sediment, after long-term deposition, cannot completely flow with the water flow. Therefore, the position of the mixer and extraction pump needs to be constantly adjusted during the mixing and extraction process, which reduces the efficiency of sediment extraction.

[0004] Therefore, we need to develop a comprehensive sediment treatment device for water conservancy projects that can gather sediment into the extraction range and facilitate sediment extraction in order to solve the above-mentioned technical problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

Detailed Implementation

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example 1: A comprehensive sediment treatment device for water conservancy projects, such as Figure 1 and Figure 2 As shown, it includes a sand suction device 1, a limiting mechanism 2, and a tightening mechanism 3. The limiting mechanism 2 is rotatably installed at the lower part of the sand suction device 1, and the tightening mechanism 3 is slidably installed at the lower part of the limiting mechanism 2. The tightening mechanism 3 can gather the mud and sand.

[0029] like Figure 3 As shown, the limiting mechanism 2 includes a first spring 21, a first limiting plate 22, a first connecting rod 23, and a second limiting plate 24. The lower part of the sand suction device 1 is fixedly connected to the first limiting plate 22. The sand suction device 1 and the first connecting rod 23 are fixedly connected to the first spring 21. The lower part of the second limiting plate 24 is provided with fixing blocks around its perimeter. The sand suction device 1 is slidably connected to the first connecting rod 23. The second limiting plate 24 and the first connecting rod 23 are fixedly connected.

[0030] like Figure 4 and Figure 5As shown, the tightening mechanism 3 includes a first telescopic rod 31, a second spring 32, a first tightening plate 33, a second tightening plate 34, a pull rope 35, a third spring 36, and a connecting block 37. The second limiting plate 24 has first telescopic rods 31 fixedly connected to both sides. A first tightening plate 33 is slidably connected to each of the two first telescopic rods 31. A second spring 32 is sleeved on one end of each of the two first telescopic rods 31 near the first tightening plate 33. The two ends of the second spring 32 are respectively sleeved on the first telescopic rod 31 and the first tightening plate 33. A wedge-shaped block is fixedly connected to the front end of the left first tightening plate 33, and a guide rod is provided at the rear end of the left first tightening plate 33. A second tightening plate 34 is slidably fixedly connected to the guide rod. A third spring 36 is fitted on the guide rod. The two ends of the third spring 36 are respectively connected to the first tightening plate 33 and the guide rod. A wedge block is fixed to the rear end of the first tightening plate 33 on the right side. A guide rod is also provided at the front end of the first tightening plate 33 on the left side. A second tightening plate 34 is slidably fixed to the guide rod. A third spring 36 is fitted on the guide rod. The two ends of the third spring 36 are respectively connected to the first tightening plate 33 and the guide rod. A connecting block 37 is connected to the two stirring blades at the bottom of the sand suction device 1. A pull rope 35 is connected between the middle of the first tightening plate 33 and the connecting block 37. One end of the pull rope 35 is fixedly connected to the middle of the first tightening plate 33. The pull rope 35 is wrapped around the connecting block 37.

[0031] When it is necessary to remove silt from the water, a crane is used to place the device on the silt and press it down. The fixing block at the bottom of the second limiting plate 24 sinks into the silt. The crane applies downward force to the sand suction device 1, causing it to move downward. The sand suction device 1 drives the limiting mechanism 2 to move downward into the silt. The sand suction device 1 drives the first limiting plate 22 and the first connecting rod 23 to move downward and contact the deposited silt. At this time, the first spring 21 is stretched, and the first connecting rod 23 rotates downward around the central axis of the sand suction device 1. The first connecting rod 23 drives the second limiting plate 24 to move downward into the silt. Then, the sand suction device 1 is opened, and the shaft in the two first limiting plates 22 rotates. The shaft drives the lower agitator to rotate, and the agitator mixes the silt and water. After that, the sand suction device 1 begins to mix the silt and water. Water is drawn in, and the drawn-in mud and water are sprayed out from the upper outlet. When the sand suction device 1 starts to draw in mud and water, the shaft at the bottom of the sand suction device 1 rotates, which drives the connecting block 37 to rotate. The connecting block 37 pulls the pull rope 35 connected at the lower end. The pull rope 35 moves the first tightening plates 33 on both sides toward the middle. At this time, the first telescopic rod 31 is stationary, and the second spring 32 is stretched. Then, when the second tightening plate 34 touches the inclined block on the other side of the first telescopic rod 31, the second tightening plate 34 moves along the inclined block toward the inner limiting mechanism 2. The third spring 36 is compressed. When the first tightening plate 33 is locked, the pull rope 35 is tightened, so that the connecting block 37 stops rotating. The tightening mechanism 3 completes the collection of mud and sand at the bottom. This process facilitates the extraction of mud and sand by the sand suction device 1. After the user finishes using the device, the sand suction device 1 is turned off, and the pressure of the crane on the sand suction device 1 is released. At this time, the first spring 21 returns to its original position, and the first spring 21 drives the sand suction device 1 to move upward. The rotating block at the bottom of the first limit plate 22 stops rotating, the pull rope 35 is released, the second spring 32 returns to its original position, and the second spring 32 drives the first tightening plate 33 to move outward. The third spring 36 returns to its original position, and the third spring 36 drives the second tightening plate 34 to move outward, finally returning to the initial position.

[0032] Example 2: Based on Example 1, such as Figure 6As shown, it also includes a shaking mechanism 4. Two shaking mechanisms 4 are provided on the front and rear sides of the limiting mechanism 2 to shake the mud and sand that are stuck together. The two shaking mechanisms 4 are symmetrically distributed from left to right. The shaking mechanism 4 includes a third limiting plate 41, a shaking plate 42, a second telescopic rod 43, a fourth spring 44, and a protrusion 45. The two ends of the two first tightening plates 33 are fixedly provided with the third limiting plate 41. There are four third limiting plates 41. The third limiting plates 41 are L-shaped and are all directly above the second tightening plate 34. The front and rear sides of the second limiting plate 24 are fixedly connected with two protrusions 45. The two protrusions 45 on the front and rear sides are symmetrical from left to right. The lower end of the protrusions 45 is slidably connected to the second telescopic rod 43. The lower side of the second telescopic rod 43 is connected to the shaking plate 42. The shaking plate 42 can strike the third limiting plate 41. The fourth spring 44 is connected between the protrusions 45 and the second telescopic rod 43.

[0033] like Figure 7 and Figure 8 As shown, it also includes a pressing mechanism 5. The pressing mechanism 5 is rotatably provided in the upper part of the limiting mechanism 2. The pressing mechanism 5 includes a third telescopic rod 51, a fifth spring 52, a pressing plate 53, a fourth limiting plate 54, and a second connecting rod 55. The sand suction device 1 is fixedly provided with the third telescopic rod 51 on the left and right sides. The third telescopic rod 51 has an L-shaped structure. The lower part of the third telescopic rod 51 is slidably connected to the pressing plate 53. The lower part of the third telescopic rod 51 and the pressing plate 53 are connected to the fifth spring 52. The lower part of the third telescopic rod 51 on the left and right sides passes through the fifth spring 52. The lower part of the pressing plate 53 is fixedly connected to the second connecting rod 55 on the left and right sides. The upper part of the middle part of the first tightening plate 33 is connected to the fourth limiting plate 54. The upper part of the fourth limiting plate 54 contacts the lower part of the second limiting plate 24.

[0034] like Figure 9 As shown, it also includes a striking mechanism 6. The striking mechanism 6 is connected to the upper right side of the lower pressure plate 53. The striking mechanism 6 includes a third connecting rod 61, a torsion spring 62 and a striking plate 63. The third connecting rod 61 is fixedly connected to the upper right side of the second limiting plate 24. The striking plate 63 is rotatably connected to the third connecting rod 61. The striking plate 63 can strike the lower pressure plate 53. Torsion springs 62 are connected to both the left and right sides between the striking plate 63 and the third connecting rod 61.

[0035] like Figure 10 As shown, it also includes a cleaning mechanism 7. The cleaning mechanism 7 is fixedly installed on the sand suction device 1. The cleaning mechanism 7 also includes a water pump 71 and a nozzle 72. The water pump 71 is installed on the upper part of the sand suction device 1. The water pump 71 has an inlet on the left side that can be connected to an external water pipe. The nozzle 72 is connected to the right side of the water pump 71.

[0036] When the crane applies downward pressure to the sand suction device 1, the sand suction device 1 drives the third telescopic rod 51 to move downward, the third telescopic rod 51 drives the lower pressure plate 53 to move downward, and the fifth spring 52 is compressed. When the sand suction device 1 is started, the connecting block 37 starts to rotate, the connecting block 37 tightens the pull rope 35, the pull rope 35 drives the first tightening plate 33 to move towards the middle, the first tightening plate 33 drives the fourth limiting plate 54 to move towards the middle, the fourth limiting plate 54 contacts the second connecting rod 55, causing the second connecting rod 55 to move downward, the second connecting rod 55 drives the lower pressure plate 53 to move downward, causing the fifth spring 52 to stretch downward, and the lower pressure plate 53 presses the mud and sand downward to prevent the mud and sand from splashing when it is stirred and extracted. When the first tightening plate 33 moves towards the center, the third limiting plate 41 also moves towards the center along with the first tightening plate 33. During the movement, when the highest point of the third limiting plate 41 contacts the shaking plate 42, the shaking plate 42 moves upward, the second telescopic rod 43 moves upward, and the fourth spring 44 is compressed upward. Then, the third limiting plate 41 continues to move with the first tightening plate 33. When the third limiting plate 41 passes the lowest point of the shaking plate 42, the fourth spring 44 resets. The fourth spring 44 drives the second telescopic rod 43 to move downward, and the second telescopic rod 43 drives the shaking plate 42 to move downward. The shaking plate 42 strikes the third limiting plate 41 downward. At this time, the mud and sand adhering to the tightening mechanism 3 are knocked off. When the fourth limiting plate 54 moves to the uppermost end of the inclined surface of the second connecting rod 55, the fourth limiting plate 54 stops moving, causing the first tightening plate 33 to stop moving, and the tightening mechanism 3 to stop tightening. After the device is used, the sand suction device 1 is turned off, the connecting block 37 stops rotating, the tension of the connecting block 37 on the rope disappears, the second spring 32 resets, causing the first tightening plate 33 to move outward, and the third limiting plate 41 also moves outward with the first tightening plate 33. When the highest point of the third limiting plate 41 contacts the shaking plate 42, the shaking plate 42 moves upward, the second telescopic rod 43 moves upward, and the fourth spring 44 is compressed upward. Then the third limiting plate 41 continues to move with the first tightening plate 33. When the third limiting plate 41 passes the lowest point of the shaking plate 42, the fourth spring 44 resets, and the fourth spring 44 drives the second telescopic rod 43 to move downward, and the second telescopic rod 43 drives the shaking plate 42 to move downward. After the pressure of the crane on the sand suction device 1 is released, the first spring 21 resets, and the first spring 21 drives the sand suction device 1 to move upward. The fifth spring 52 resets, and the fifth spring 52 drives the lower pressure plate 53 to move upward. Then, people can pull the handle on the striking plate 63 to lift it up, causing the torsion spring 62 to deform. After releasing the handle, the torsion spring 62 returns to its original position, causing the striking plate 63 to knock down the pressure plate 53, dislodging the mud and sand adhering to the pressure plate 53. Finally, people can connect a water pipe to the water pump 71, start the water pump 71, and turn on the nozzle 72 to clean the device.
