Description

Technical Field

[0002] After searching, the patent with publication number CN219732121 U discloses a silt removal device for water conservancy project management. The device breaks up the silt settled at the bottom of the reservoir by means of stirring rods equidistantly arranged on the outer surface of the shaft rod while sliding. The slide plate drives the bracket to slide inside the reservoir, so that the stirring rods can break up the silt at the bottom of the reservoir more thoroughly, thereby increasing work efficiency.

[0003] The stirring rod in the above-mentioned device can play a certain role in breaking up the silt at the bottom of the reservoir. However, there is a distance between the stirring rods, which means that there are dead corners that the stirring rods cannot cover, such as the gaps between the stirring rods or the corners that the stirring rods cannot reach. In these areas, the silt will maintain a high concentration and thickness and will not be easily affected by the stirring rods, which will make it impossible to fully clean the silt at the bottom of the reservoir, resulting in poor dredging effect. Therefore, a dredging device for water conservancy project management is needed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] There are many kinds of devices used for dredging in water conservancy project management, one of which is called a submersible pump dredging device. This device usually includes a submersible pump and related pipes, hoses and other accessories. A submersible pump is a pump that can work underwater, usually driven by an electric motor. It can be placed in the water body that needs to be dredged, sucking in silt and water, and then transporting it to other places, such as sedimentation tanks, treatment equipment or discharge areas. It is often used to clean up rivers, lakes, reservoirs and other waters, and is one of the commonly used dredging equipment in water conservancy project management.

[0024] Example

[0025] The stirring rods in the existing devices can play a certain role in breaking up the silt at the bottom of the reservoir. However, there are gaps between the stirring rods, which means that there are dead corners that the stirring rods cannot cover, such as the gaps between the stirring rods or the corners that the stirring rods cannot reach. In these areas, the silt will maintain a high concentration and thickness and will not be easily affected by the stirring rods, which will make it impossible to fully clean the bottom of the reservoir, resulting in poor dredging effect. Figure 1-Figure 4 The embodiment provides a silt removal device for water conservancy project management, including a water reservoir 1 and a moving mechanism 2 arranged on the top of the water reservoir 1. The moving mechanism 2 is a prior art and can drive the connecting rod 31 to move back and forth horizontally, which will not be described in detail.

[0026] refer to Figure 2-Figure 4As shown, there are dead angle areas that the stirring rod 44 cannot cover, such as the gaps between the stirring rods 44 or the corners that the stirring rods 44 cannot reach. In these areas, the sludge will maintain a high concentration and thickness and will not be easily affected by the stirring rods 44, thereby making it impossible to fully clean the sludge at the bottom of the water reservoir 1, resulting in a poor dredging effect. In order to ensure that the bottom of the water reservoir 1 can be fully cleaned and treated, the following settings are made: a dredging assembly 3 for cleaning the sludge under the synchronous drive of the moving mechanism 2 is provided at the inner bottom of the water reservoir 1. The dredging assembly 3 includes a connecting rod 31 fixed to the bottom of the moving mechanism 2, and the bottom end of the connecting rod 31 is fixedly connected to a semicircular plate 32. The bottom of the semicircular plate 32 is symmetrically fixedly connected to two mounting plates 33. The two mounting plates The bottom of the plate 33 is fixedly connected to a cylindrical tube 34, and a control rod 35 is sleeved inside the cylindrical tube 34. Both ends of the control rod 35 protrude from the inside of the cylindrical tube 34 and are fixedly connected to a shoveling plate 38. The shoveling plate 38 is arranged obliquely in the water reservoir 1, and the side of the shoveling plate 38 away from the control rod 35 is an acute angle, so that the shoveling plate 38 can shovel up and clean the silt deposited at the bottom of the water reservoir 1. The movement of the connecting rod 31 can drive the shoveling plate 38 to move at the bottom of the water reservoir 1 and then clean the silt deposited at the bottom of the water reservoir 1. By moving the shoveling plate 38, more areas can be covered to ensure that the silt is fully cleaned, reduce the area that is not covered, ensure that the bottom of the entire water reservoir 1 is cleaned, and avoid the situation where local silt is not treated.

[0027] refer to Figure 4 As shown, long-term friction and sliding contact will cause the bottom of the shovel plate 38 to be worn thin, thereby affecting its effective contact with the bottom of the water tank 1, thereby reducing the dredging effect. In order to prevent this from happening, the following settings are made. The interior of the cylindrical tube 34 is provided with an adjustment component for making the shovel plate 38 close to the bottom of the water tank 1. The adjustment component includes two circular rings 36 that rotate symmetrically at both ends of the control rod 35. The two circular rings 36 are fixed inside the cylindrical tube 34. The outer wall of the control rod 35 is symmetrically sleeved with two torsion springs 37. The two ends of the two torsion springs 37 are respectively fixedly connected to the circular rings 36 and the control rod 35. When the bottom of the shovel plate 38 is worn thin, the control rod 35 functions to adjust the position of the shovel plate 38 through the torsion of the torsion spring 37. When the torsion spring 37 applies sufficient torsion, the control rod 35 will be rotated, thereby adjusting the position of the shovel plate 38 so that it maintains close contact with the bottom of the water tank 1, ensuring that when the bottom of the shovel plate 38 is worn thin, the silt at the bottom of the pool can still be effectively cleaned, thereby improving the dredging efficiency.

[0028] refer to Figure 2-Figure 3As shown, after a period of accumulation, the silt forms hard lumps or agglomerates, making it difficult to remove. By breaking up the silt, it can be broken down into smaller particles. In order to make the removal work easier and more efficient, the following configuration is specially made. The reservoir 1 is provided with a crushing assembly 4 for breaking up the silt under the synchronous drive of the dredging assembly 3. The crushing assembly 4 includes a plurality of stirring rods 44 symmetrically arranged on the opposite sides of the two mounting plates 33. Two stabilizing plates are symmetrically arranged on the opposite sides of the two mounting plates 33. A rotating shaft 43 is rotatably connected between the two stabilizing plates. The plurality of stirring rods 44 are equidistant laterally. Two limit plates 5 are fixed to the outer wall of the rotating shaft 43 and are symmetrically fixed to the inner wall of the water storage tank 1. A groove is provided on the side of one of the limit plates 5. A rack 41 is fixed to the inner bottom wall of the groove. The rack 41 is meshed with a gear 42. The gear 42 is fixed to the outer wall of the rotating shaft 43. A stabilizing plate 45 is provided on the side of the two limit plates 5 away from the gear 42. The rotating shaft 43 rotates inside the stabilizing plate 45. A slider is fixed to the side of the stabilizing plate 45 close to the limit plate 5. A slide groove is provided on the side of the two limit plates 5 close to the stabilizing plate 45. The slider slides left and right along the length direction of the slide groove. When the two mounting plates 33 move, the gear 42 is driven to mesh with the rack 41 to rotate the rotating shaft 43. The rotation of the rotating shaft 43 drives a number of stirring rods 44 to rotate and then crush the sludge shoveled by the shoveling plate 38. Through the rotation of the stirring rod 44, the sludge is stirred and crushed into smaller particles, so that the dredging equipment can remove it more easily, which can improve the efficiency and thoroughness of dredging.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
