Description

Technical Field

[0001] This utility model relates to the field of silt removal technology, specifically to a silt removal device for water conservancy projects. Background Technology

[0002] Silt removal equipment for water conservancy projects is a type of professional machinery that integrates multiple functions. It is usually driven by a power system to create a suction device that breaks up hardened silt with rotating blades. The silt is then sucked into a pipeline by a powerful suction force and transported to a designated area by a mud pump. It is also equipped with an intelligent navigation and positioning system, which can accurately control the equipment to operate in complex waters. Some models also have a silt dewatering and solidification module, realizing the integration of silt removal, transportation and treatment. This effectively improves the efficiency and quality of river dredging and reservoir dredging in water conservancy projects, ensuring smooth water flow and project safety. For example, Chinese Patent No. CN222025149U discloses a silt removal equipment for water conservancy projects.

[0003] Existing silt removal equipment used in water conservancy projects often suffers from silt dispersion due to long-term water erosion, water flow, and disturbances from the daily operation of the water conservancy project. The silt particles are small and easily dispersed by the water flow, making natural aggregation difficult. This results in the equipment being unable to concentrate silt around its perimeter, leading to low silt removal efficiency, high silt residue in the area covered by a single operation, and the need for repeated cleaning, increasing operation time and costs. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a silt removal device for water conservancy projects. This device effectively solves the problem that, during silt removal, the silt remains dispersed due to long-term water erosion, water flow, and disturbances caused by the daily operation of water conservancy projects. Furthermore, the silt particles are small and easily dispersed by water flow, making natural aggregation difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a silt removal device for water conservancy projects, comprising: The base has four bases, and each base has a driver fixedly connected to its upper end surface. Each driver has a top plate fixedly connected to its upper end surface. A sludge pump is fixedly connected to the center of the upper end surface of the top plate, and the output end of the sludge pump passes through the top plate and extends to the bottom of the top plate.

[0006] Furthermore, a buffer assembly is provided at the center of each of the four sides of the upper surface of the top plate. The buffer assembly includes a fixed block fixedly connected to the upper surface of the top plate. A fixed rod is fixedly connected to the side of the fixed block away from the sludge pump, and a connecting block is fixedly connected to the other side of the fixed rod. A counterweight structure is provided at the bottom of the connecting block.

[0007] Furthermore, the counterweight structure includes a connecting rod fixedly connected to the bottom of the connecting block, two counterweight balls fixedly connected to the other side of the connecting rod, an elastic rod fixedly connected between the two counterweight balls, and a buffer cover fixedly connected to the other side of one of the counterweight balls.

[0008] Furthermore, a dirt-removing assembly is provided between each of the two adjacent drivers. The dirt-removing assembly includes a pair of rotating shafts fixedly connected to the output end of the driver. The outer circumferential surfaces of the pair of rotating shafts are surrounded by a conveyor belt. Multiple dirt-collecting structures are arranged in a linear array around the side of the conveyor belt.

[0009] Furthermore, the dirt-collecting structure includes an arc-shaped cover fixedly connected to the side of the conveyor belt. The arc-shaped cover has multiple holes arranged in a linear array on its arc surface. Multiple separators are fixedly connected in a linear array on the arc surface between two adjacent holes. Multiple brushes are fixedly connected in a linear array on the edge of the arc-shaped cover away from the conveyor belt.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. The buffer assembly, consisting of a fixed block, a fixed rod, a connecting block, and a counterweight structure, buffers the sludge pump when it contacts the sludge surface and increases the distance between the pump and the surface. The fixed block, fixed rod, and connecting block together form an L-shaped frame to extend and fix the counterweight structure. The counterweight structure, utilizing its own weight and elasticity, buffers the sludge pump upon contact with the sludge surface and also secures it, reducing the impact of water flow on the pump. The counterweight structure, relying on its own weight and elasticity, effectively buffers the impact force at the moment the pump contacts the sludge surface, preventing equipment damage and extending its service life. Simultaneously, this design increases the distance between the pump and the surface, preventing the pump from sinking into the sludge and ensuring normal operation. Furthermore, the counterweight structure's fixation of the pump reduces the interference of water flow on the equipment, enhancing operational stability.

[0011] 2. Through the rotating shaft, conveyor belt, and sludge-gathering structure in the sludge-collecting assembly, the sludge around the sludge pump is gathered around the pump. The rotating shaft is driven by a driver, which in turn drives the conveyor belt. The rotating conveyor belt connects to the sludge-gathering structure, effectively gathering the sludge around the pump. This effectively solves the problem of scattered sludge that is difficult to collect, and can quickly gather the scattered sludge around the pump body, enabling the sludge pump to efficiently collect sludge, improving dredging efficiency, and reducing the problem of ineffective operation of the equipment due to sludge dispersion.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Example: Refer to Figures 1 to 2 A silt removal device for water conservancy projects, comprising: The base 1 has four bases. Each base 1 has a driver 2 fixedly connected to its upper surface. Each driver 2 has a top plate 3 fixedly connected to its upper surface. A sludge pump 4 is fixedly connected to the center of the upper surface of the top plate 3. The output end of the sludge pump 4 passes through the top plate 3 and extends to the bottom of the top plate 3.

[0018] The base 1 is used to fix the driver 2, and the driver 2 is also fixed by the top plate 3, thereby fixing the sludge pump 4 by the top plate 3.

[0019] Reference Figures 2 to 3 A buffer assembly 5 is provided at the center of all four sides of the upper surface of the top plate 3. The buffer assembly 5 includes a fixing block 51 fixedly connected to the upper surface of the top plate 3. A fixing rod 52 is fixedly connected to the side of the fixing block 51 away from the sludge pump 4. A connecting block 53 is fixedly connected to the other side of the fixing rod 52. A counterweight structure 54 is provided at the bottom of the connecting block 53.

[0020] The fixing block 51, fixing rod 52 and connecting block 53 in the buffer assembly 5 are used to form an L-shaped frame to realize the installation of the counterweight structure 54.

[0021] Reference Figures 2 to 3 The counterweight structure 54 includes a connecting rod 541 fixedly connected to the bottom of the connecting block 53. Two counterweight balls 542 are fixedly connected to the other side of the connecting rod 541. An elastic rod 543 is fixedly connected between the two counterweight balls 542. A buffer cover 55 is fixedly connected to the other side of one of the counterweight balls 542.

[0022] The connecting rod 541 in the counterweight structure 54 is used to connect with the connecting block 53, thereby transferring the gravity of the top plate 3 to the connecting rod 541. The connecting rod 541 contains a counterweight ball 542 and an elastic rod 543.

[0023] Reference Figure 2 , Figures 4 to 5Each of the two adjacent drivers 2 is provided with a dirt removal assembly 6. The dirt removal assembly 6 includes a pair of rotating shafts 61 fixedly connected to the output end of the driver 2. The outer circumference of the pair of rotating shafts 61 is surrounded by a conveyor belt 62. Multiple dirt collection structures 63 are arranged in a linear array around the side of the conveyor belt 62.

[0024] The drive 2 drives the rotating shaft 61 to rotate, and the rotating shaft 61 synchronously drives the conveyor belt 62 to rotate. The rotating conveyor belt 62 connects to the sludge collection structure 63 installed therein, and collects the sludge around the sludge pump 4.

[0025] Reference Figure 5 The pollution collection structure 63 includes an arc-shaped cover 631 fixedly connected to the side of the conveyor belt 62. The arc surface of the arc cover 631 has multiple holes 632 in a linear array. Multiple separators 633 are fixedly connected to the arc surface of the arc cover 631 between two adjacent holes 632 in a linear array. Multiple divider brushes 634 are fixedly connected to the edge of the arc cover 631 away from the conveyor belt 62 in a linear array.

[0026] The sludge is collected by the arc-shaped cover 631 in the sludge collection structure 63, while the water in the sludge is released through the holes 632 in the arc-shaped cover 631.

[0027] The working principle of this utility model is as follows: First, the operator transports the equipment to the area to be dredged, placing the four bases 1 stably on the bottom or bank to ensure stability. The actuators 2 on each base 1 are then activated sequentially. The actuators 2, through power output, keep the top plate 3 level, providing stable support for the sludge pump 4. Then, the sludge pump 4 at the center of the top plate 3 is started, its output extending downwards to the bottom of the top plate 3. At this point, the buffer components 5 around the top plate 3 begin to function: the fixing block 51, fixing rod 52, and connecting block 53 form an L-shaped support, extending the counterweight structure 54 to the perimeter of the equipment. In the counterweight structure 54, the connecting rod 541 connects to the connecting block 53, and the two counterweight balls 542 rely on their own weight to maintain a safe distance between the sludge pump 4 and the sludge ground, preventing the pump from sinking. The elastic rod 543 buffers the impact when the sludge pump 4 contacts the sludge, and the buffer cover 55 reduces the descent speed of the equipment by increasing the contact area, ensuring smooth operation.

[0028] The operator controls the driver 2, which drives a pair of rotating shafts 61 at its output end to rotate, thereby driving the conveyor belt 62 to circulate. The sludge-collecting structure 63 on the conveyor belt 62 moves with the conveyor belt 62. The arc surface of the arc-shaped cover 631 gathers the dispersed sludge towards the sludge pump 4; the holes 632 release moisture from the sludge, improving the collection efficiency; the separator 633 prevents the sludge from sticking and clumping together inside the arc-shaped cover 631; and the dividing brush 634 scrapes the sludge into the arc-shaped cover 631, causing the sludge to concentrate around the pump body. Once the silt accumulates around the silt pump 4, the suction function of the silt pump 4 is activated, drawing the concentrated silt into the pipe through the output end, and then transporting it through the pump body to the silt treatment area or transport container on the shore, completing a single dredging operation.

[0029] Once the current area has been cleared, the operator adjusts the output power of the driver 2 to control the equipment to move to the next work area, repeating the above steps until the silt removal task of the entire water area is completed. After the operation is completed, first turn off the sludge pump 4, and then stop the drive 2. Check whether the counterweight ball 542 and elastic rod 543 of the buffer assembly 5 are intact, clean the residual sludge in the sludge collection structure 63, and ensure that the arc-shaped cover 631, the dividing brush 634 and other components are not blocked, so as to perform maintenance for subsequent use.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
