Description

Technical Field

[0001] This invention belongs to the field of tunnel dredging technology, specifically relating to a dredging device for underground tunnel drainage ditches. Background Technology

[0002] In existing underground roadways, drainage ditches are severely silted up. Current technology usually involves manual dredging for regular cleaning, which results in a huge workload for workers. Not only is the frequency of work low and the intensity of work high, but it also greatly affects the dredging efficiency of underground drainage ditches. If dredging is not done in time, it will cause blockage of the drainage ditches. In other words, the current dredging method is extremely inefficient and affects the working environment of underground roadways.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a sludge removal device for underground roadway drainage ditches, so as to at least solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sludge removal device for underground roadway drainage ditches, wherein a sedimentation tank is set at intervals in the drainage ditch, and a sludge removal device is set between two adjacent sedimentation tanks;

[0007] The sludge remover includes:

[0008] A tracked vehicle has tracked tracks laid at the bottom of the drainage ditch along its extension direction, and the tracked vehicle moves on the tracked tracks.

[0009] A serrated shovel blade is installed at the front end of the tracked vehicle. As the tracked vehicle moves forward, the serrated shovel blade scoops up the silt in the drainage ditch.

[0010] The storage mechanism is located at the rear end of the tracked vehicle. During the forward movement of the tracked vehicle, sludge accumulates in the storage mechanism and is unloaded into the sedimentation tank after the vehicle moves to the sedimentation tank position.

[0011] In the underground roadway drainage ditch sludge scavenger described above, preferably, the front end of the tracked drive vehicle has an inclined structure, and the inclined structure is transitionally connected to the sawtooth shovel blade.

[0012] In the underground roadway drainage ditch sludge cleaner described above, preferably, both sides of the front end of the tracked vehicle are provided with elastic guide mechanisms. The elastic guide mechanism includes at least a guide wheel, which contacts the side wall of the drainage ditch and rolls against the side wall of the drainage ditch.

[0013] In the underground roadway drainage ditch sludge scavenger described above, preferably, the elastic guiding mechanism further includes a guide rod, one end of which is hinged to the front end of the tracked drive vehicle, and a guide wheel is rotatably mounted on the other end.

[0014] In the underground roadway drainage ditch sludge scavenger described above, preferably, a torsion spring is provided between the guide rod and the tracked drive vehicle to allow the guide rod to elastically extend toward the side wall of the drainage ditch.

[0015] Preferably, in the underground roadway drainage ditch sludge cleaner described above, the storage mechanism includes a storage tank with an opening at the bottom.

[0016] In the underground roadway drainage ditch sludge cleaner described above, preferably, the storage mechanism further includes a pair of shear plates hinged at the bottom of the storage tank, which block the opening when closed.

[0017] In the underground roadway drainage ditch sludge cleaner described above, preferably, the shear plate has an L-shaped structure.

[0018] In the underground roadway drainage ditch sludge cleaner described above, preferably, the inflection point of the L-shaped shear plate is hinged to the bottom of the storage tank.

[0019] As described above, the underground roadway drainage ditch sludge cleaner preferably has a pair of blocks at the bottom of the drainage ditch in front of the sedimentation tank. When the tracked vehicle moves forward to the position of the blocks, the blocks and one side of the L-shaped scissor blades block each other, causing the pair of scissor blades to rotate outward to open the opening at the bottom of the storage tank.

[0020] Beneficial effects:

[0021] In this sludge dredger, as the tracked vehicle moves forward along the track in the drainage ditch, the serrated blades at the front scoop up the sludge and, with the forward movement of the tracked vehicle, transport the sludge to a storage mechanism at the rear of the vehicle for temporary storage. This not only collects the sludge from the drainage ditch but also clears the sludge at the front of the tracked vehicle, thus not affecting its forward movement. When the tracked vehicle reaches the sedimentation tank, the storage mechanism unloads the stored sludge into the sedimentation tank. At this point, only point-to-point cleaning of the sludge in the drainage ditch is required. Water can be added to the sedimentation tank to dilute the sludge, and a sludge pump can be used to extract and transport the sludge. This sludge dredger greatly reduces the labor intensity of dredging work and improves work efficiency.

[0022] When a pair of shear plates close together, they seal the opening, allowing the storage tank to store sludge. When the tracked vehicle moves to the sedimentation tank, the pair of shear plates rotate and open, so that the opening at the bottom of the storage tank faces the sedimentation tank, making it easier to unload the sludge temporarily stored in the storage tank into the sedimentation tank.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "connected" and "linked" used in this invention should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0030] According to specific embodiments of the present invention, such as Figure 1-2 As shown, the present invention provides a sludge removal device for underground roadway drainage ditches, wherein a sedimentation tank 10 is set at intervals in the drainage ditch, and a sludge removal device is set between two adjacent sedimentation tanks 10.

[0031] The sludge removal device includes:

[0032] Tracked vehicle 1 has track rails 7 laid at the bottom of the drainage ditch along the extension direction of the drainage ditch, and tracked vehicle 1 moves on track rails 7.

[0033] The serrated blade 2 is located at the front end of the tracked vehicle 1. As the tracked vehicle 1 moves forward, the serrated blade 2 scoops up the silt in the drainage ditch.

[0034] The storage mechanism is located at the rear end of the tracked vehicle 1. During the forward movement of the tracked vehicle 1, the sludge accumulates in the storage mechanism and is unloaded into the sedimentation tank 10 after the vehicle moves to the position of the sedimentation tank 10.

[0035] In this sludge dredger, as the tracked vehicle 1 moves forward along the track 7 in the drainage ditch, the serrated blade 2 at the front end scoops up the sludge in the drainage ditch and, driven by the forward movement of the tracked vehicle 1, transports the sludge to the storage mechanism at the rear end of the tracked vehicle 1 for temporary storage. This not only collects the sludge in the drainage ditch but also clears the sludge at the front end of the tracked vehicle 1, thus not affecting the forward movement of the tracked vehicle 1. When the tracked vehicle 1 moves to the sedimentation tank 10, the storage mechanism unloads the stored sludge into the sedimentation tank 10. At this point, only point-to-point cleaning of the sludge in the drainage ditch is required. Water can be added to the sedimentation tank 10 to dilute the sludge, and a sludge pump can be used to extract and transport the sludge. This sludge dredger greatly reduces the labor intensity of sludge dredging work and improves work efficiency.

[0036] After completing one dredging operation, the dredging device can be manually transported to the starting point of the dredging so that it can be used to repeat the dredging operation.

[0037] The front end of the tracked vehicle 1 is an inclined structure, which is transitionally connected to the serrated shovel 2. In one embodiment of this application, the inclined structure at the front end of the tracked vehicle 1 facilitates the gradual transfer of sludge to the rear end of the tracked vehicle 1 during forward movement, thereby facilitating the transfer and storage of the sludge.

[0038] Both sides of the front end of the tracked vehicle 1 are provided with elastic guide mechanisms 3. The elastic guide mechanism 3 includes at least guide wheels 32, which contact the sidewall of the drainage ditch and roll along the sidewall. In one embodiment of this application, the elastic guide mechanism 3 is provided at the front end of the tracked vehicle 1 to facilitate the tracked vehicle 1 to move in the drainage ditch with a certain curvature, so that the sludge remover can adapt to drainage ditches with different curvatures.

[0039] The elastic guiding mechanism 3 also includes a guide rod 31, one end of which is hinged to the front end of the tracked vehicle 1, and the other end is rotatably equipped with a guide wheel 32. In one embodiment of this application, the guide rod 31 serves as an extension of the guide wheel 32, enabling the tracked vehicle 1 to adapt to drainage ditches of different widths.

[0040] A torsion spring is provided between the guide rod 31 and the tracked drive vehicle 1 to allow the guide rod 31 to elastically extend toward the side wall of the drainage ditch. In one embodiment of this application, the torsion spring enables the guide rod 31 to elastically contact the side wall of the drainage ditch, thereby allowing the tracked drive vehicle 1 to achieve smoother steering in drainage ditches of different widths.

[0041] The storage mechanism includes a storage tank 4, with an opening at the bottom. In one embodiment of this application, the storage tank 4 facilitates the temporary storage of sludge, while the opening at the bottom of the storage tank 4 facilitates the unloading of the sludge into the sedimentation tank 10.

[0042] The storage mechanism also includes a pair of shear plates 5 hinged to the bottom of the storage tank 4. When the pair of shear plates 5 are closed, they seal the opening. In one embodiment of this application, when the pair of shear plates 5 are closed, they seal the opening so that the storage tank 4 can store sludge. When the tracked vehicle 1 moves to the sedimentation tank 10, the pair of shear plates 5 rotate and open so that the opening at the bottom of the storage tank 4 faces the sedimentation tank 10, allowing the sludge temporarily stored in the storage tank 4 to be unloaded into the sedimentation tank 10.

[0043] The scissor plate 5 has an L-shaped structure. The inflection point of the L-shaped scissor plate 5 is hinged to the bottom of the storage tank 4. In one embodiment of this application, pushing one side of the L-shaped scissor plate 5 will cause the scissor plate 5 to rotate, thereby controlling the closing and opening process of the opening.

[0044] A pair of blocks 6 are installed at the bottom of the drainage ditch in front of the sedimentation tank 10. When the tracked vehicle 1 moves forward to the position of the blocks 6, the blocks 6 and one side of the L-shaped scissor plate 5 block each other, causing the pair of scissor plates 5 to rotate outward to open the opening at the bottom of the storage tank 4. In one embodiment of this application, when the blocks 6 and one side of the L-shaped scissor plate 5 block each other and interfere, as the tracked vehicle 1 moves forward, the L-shaped scissor plate 5 rotates around its hinge point, thereby opening the opening at the bottom of the storage tank 4. This facilitates the unloading of sludge from the storage tank 4 into the sedimentation tank 10. Then, water is added to the sedimentation tank 10 to dilute the sludge, and the diluted sludge is pumped away by a sludge pump, completing the sludge removal work in the roadway drainage ditch, thereby greatly improving the sludge removal efficiency of the roadway drainage ditch.

[0045] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention shall be within the scope of protection of the pending claims of the present invention.
