The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that all components in the technical solution of this application require the necessary additional facilities of water supply, oil supply, electricity supply and gas supply to be driven and / or controlled. If there is no further explanation, it is assumed that the existing technology is used and equipped without special explanation.

[0024] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Depend on Figure 1 A culvert silt cleaning device shown in the figure includes a silt removal cylinder 1, one end of the silt removal cylinder 1 is closed, and the other end of the silt removal cylinder 1 is open. The closed end surface of the silt removal cylinder 1 is rotatably connected to a tilting head assembly for adjusting the height of one end thereof. The silt removal cylinder 1 is a semi-cylindrical structure. The top surface of the silt removal cylinder 1 is detachably connected to a cover plate 2, and a mounting hole 3 is provided on the top surface of the cover plate 2. A one-way flow assembly is arranged in the mounting hole 3; both sides of the top surface of the silt removal cylinder 1 are detachably connected to traction assemblies for pulling the silt removal cylinder 1 forward and backward; the traction assemblies are fixedly connected to the ground on both sides of the river channel (not shown in the drawings) or anchor ships (not shown in the drawings).

[0026] Furthermore, the anchored ship is a construction ship anchored in a river channel, which is convenient for installing a traction component and serves as its fixing point. This is a prior art and will not be described in detail here.

[0027] The desilting cylinder 1 of the utility model can be buried in the silt at the bottom of the culvert under the action of the front and rear pulling of the traction assembly, and the silt removal cylinder 1 can continue to penetrate into the silt by utilizing the closed structure at one end of the desilting cylinder 1 and the impact of the water flow, thereby reducing the consumption of the traction power of the traction assembly. When the desilting cylinder 1 penetrates deep enough into the silt, the traction assembly at the front end of the desilting cylinder 1 pulls it forward, that is, pushes the silt out of the culvert, thereby achieving the cleaning of the culvert silt.

[0028] To further optimize the solution, Figure 3 As shown, the tilting head assembly includes a push plate 4, a rotating block 5 is fixedly connected to the bottom surface of the push plate 4, and a connecting block 6 is symmetrically fixedly connected to one end of the desilting cylinder 1. A rotating shaft 7 is inserted between the two connecting blocks 6. The rotating block 5 is rotatably connected to the rotating shaft 7, and the push plate 4 can rotate along the rotating shaft 7 under the drive of the telescopic member 18. The side of the push plate 4 away from the desilting cylinder 1 is fixedly connected with a buoy 8. The buoy 8 can use its buoyancy with the water to tilt one end of the desilting cylinder 1, so that the other end of the desilting cylinder 1 is inserted into the silt. The two sides of the push plate 4 are symmetrically fixedly connected with an articulated seat 17, and the articulated seat 17 is hinged with a telescopic member 18, and one end of the telescopic member 18 is rotatably connected to the outer side of the desilting cylinder 1. The bottom surface of the desilting cylinder 1 is fixedly connected with a limit block 9, and the end face of the limit block 9 is detachably connected to the end face of the push plate 4. The limit block 9 can provide sufficient support for the desilting cylinder 1 to prevent the desilting cylinder 1 from being over-folded under the impact of the water flow, resulting in increased pressure or even damage to the telescopic member 18. The buoy 8 is a hollow metal cylinder, and the telescopic member 18 can be used to drive the angle of the push plate 4 to adjust the tilting angle of one end of the desilting cylinder 1 .

[0029] Furthermore, the telescopic member 18 is a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, preferably a hydraulic cylinder, which is a prior art and will not be described in detail here.

[0030] To further optimize the solution, Figure 2 As shown, the one-way flow component includes a sealing plate 10, one end of which is hinged to the bottom surface of the cover plate 2, the sealing plate 10 is adapted to the mounting hole 3 and is detachably connected thereto, an elastic block 11 is fixedly connected to the bottom surface of the sealing plate 10, and the bottom end of the elastic block 11 is detachably connected to the bottom surface of the cover plate 2, the elastic block 11 can provide a certain gravity to fold the cover plate 2, and can contact the cover plate 2 to avoid folding of the sealing plate 10 in the direction thereof, thereby affecting the effect of cleaning sludge in the silt removal cylinder 1.

[0031] Further optimization scheme, the traction assembly includes a lifting ring 12, the lifting ring 12 is screwed to one end of the top surface of the desilting cylinder 1, and the cable 13 is detachably connected to the lifting ring 12 through a U-shaped ring, wherein the lifting ring 12 and the U-shaped ring are both existing lifting tools, which are prior art and are not described here. A pulley assembly 16 (whose structure is prior art, not shown in the drawings) is wound around one end of the cable 13 and is transmission-connected to a winch 14, which is fixedly connected to the ground on both sides of the river or an anchor ship.

[0032] Furthermore, the pulley assembly is fixedly connected to the ground or anchored ship on both sides of the river channel, and includes a fixed pulley, a plurality of movable pulleys and a retaining frame. It can reduce the traction force by changing the traction distance. This is a prior art and will not be described in detail here.

[0033] A further optimized solution is provided in which a chamfer is provided at one end of the silt removing cylinder 1 away from the lift-off assembly, a cavity is provided on the side wall of the silt removing cylinder 1, the cavity is filled with water, a water valve 15 is fixedly connected to and communicated with the top surface of the silt removing cylinder 1, and the water valve 15 is fixedly connected to and communicated with an external water pump (not shown in the drawings), and two water valves 15 are provided, which can respectively inject and pump water at the same time, and utilize the amount of water to adjust the center of gravity and buoyancy of the silt removing cylinder 1, so as to realize the floating and sinking of the utility model and reduce traction.

[0034] Furthermore, the water valve 15 includes a valve and a pipeline, which is convenient for draining the water in the inner cavity of the desilting cylinder 1.

[0035] As a further optimization scheme, a chamfer is provided at one end of the limit block 9 away from the buoy 8 to increase the sharpness of the edge of one end of the silt removal tube 1, so as to facilitate the insertion of the silt removal tube 1 into the sludge.

[0036] The working process of this embodiment is as follows:

[0037] The utility model is placed on the river at the bottom of the culvert. In the initial state, the inner cavity of the silt removal cylinder 1 is emptied, and the utility model will float on the water surface. At the same time, the traction components are fixedly installed on the front and rear sides of the silt removal cylinder 1 respectively. By starting the winch 14 of the traction component, the silt removal cylinder 1 is pulled into the culvert, and then the water pump is started to inject water into the inner cavity of the silt removal cylinder 1, and the silt removal cylinder 1 slowly sinks. Because one end of the silt removal cylinder 1 is closed and the water injection end is far away from the tilting head component, the silt removal cylinder 1 will sink first at the end away from the tilting head component under the impact of the water flow and the unilateral weight of the silt removal cylinder 1, and as the water injection increases, it will preferentially contact the silt at the bottom of the culvert.

[0038] At this time, in order to prevent the silt removal cylinder 1 from lying flat, the telescopic member 18 is started to drive the push plate 4, and the float is used to continue to keep one end of the silt removal cylinder 1 in an upturned state, while increasing the thrust of the water flow at the closed end of the silt removal cylinder 1, so that the silt removal cylinder 1 can gradually penetrate into the silt.

[0039] Start the winch 14 in front of the silt removal cylinder 1, pull the silt removal cylinder 1 forward continuously, and the silt removal cylinder 1 will gradually shovel a large amount of silt into its inner cavity, then empty the water in the inner cavity of the silt removal cylinder 1, use the buoyancy to drive the silt to float, and at the same time, the traction component starts to pull the silt removal cylinder 1 to float to the water surface, and the turbulent river on the water surface continuously rushes in from the installation hole 3 and flows out from the inner cavity of the silt removal cylinder 1, bringing the silt to the downstream, reducing the amount of silt in the culvert. After the silt in the silt removal cylinder 1 is flushed, start the traction component to pull the silt removal cylinder 1 back into the culvert, and repeat the above steps.

[0040] Furthermore, when the sludge needs to be excavated and transferred, the cover plate 2 can restrain the sludge in the inner cavity of the silt removal tube 1 and transfer the sludge through the ship. If the sludge only needs to be emptied and flushed downstream, the cover plate 2 and the one-way flow assembly can be removed in advance to improve the efficiency of flushing.

[0041] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
