Description

Technical Field

[0001] The utility model relates to the technical field of sludge cleaning devices, and specifically to silt cleaning equipment for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. River channels are one of the important components of water conservancy projects. After long-term use, a large amount of silt can easily accumulate at the bottom. In order to ensure the normal use of the river channel, the silt at the bottom of the river channel needs to be cleaned regularly.

[0003] The patent specification with application number 202021028050.8 discloses a dredging equipment for water conservancy projects, including a hull, a support frame is provided on the hull, a dredging device is lifted and lowered on the support frame, a water filtering device is provided on the hull, the dredging device includes a dredging platform, a sludge pump is provided on the dredging platform, a sludge shovel is provided under the dredging platform, the sludge inlet of the sludge pump is located above the sludge shovel, and a lift plate is provided at the end of the sludge shovel facing the direction of travel of the hull, which is obliquely pointed to the sludge inlet of the sludge pump, and the sludge discharge port of the sludge pump is connected to a conduit extending to directly above the water filtering device.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned dredging equipment for water conservancy projects has the problem that the excavation equipment is relatively large and heavy, which is not conducive to the use of dredging ships. When extracting silt, the suction pipe often stays on the surface of the silt during extraction, making it difficult to extract the silt cleanly. In addition, the silt structure at the extraction point is loose and has a high water content. At this time, a large amount of silt is stored inside the dredging ship, and the dredging ship needs to frequently dock at the shore to unload the silt.

[0005] Therefore, we propose a dredging device for water conservancy projects. Utility Model Content

[0028] 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.

[0029] Example 1

[0030] like Figure 1 to Figure 5As shown, this embodiment proposes a dredging equipment for water conservancy projects, including a drifting boat 1, a support frame 2 and a cleaning box 3. A notch is opened on the outer side of the cleaning box 3 to facilitate the rotation of the rotating rod 405 inside the square groove of the cleaning box 3. The outer side of the rotating rod 405 drives the outer horizontal strip of the ground dragon 404 to rotate inside the cleaning box 3. The outer side of the horizontal strip of the ground dragon 404 is attached with a rotating rod 4, and a rotary tillage blade 401 is welded to the outer side of the rotating rod 4. The bottom end of the rotary tillage blade 401 is tightly set with a telescopic rod 402, and the outer side of the telescopic rod 402 is sleeved with a spring 403. The other end of the spring 403 is tightly set on the inner wall of the cleaning box 3.

[0031] In this embodiment, the rotating rod 405 inside the cleaning box 3 drives the rotating rod 4 on the outside to approach the silt at the riverbed. At this time, the rotary tillage blade 401 on the outside of the rotating rod 4 scrapes the silt and transmits it to the outside of the horizontal ground dragon 404, and the spring 403 at the bottom of the rotating rod 4 and the telescopic rod 402 support the rotating rod 4 to prevent the rotating rod 4 from collapsing if the silt is too heavy.

[0032] Example 2

[0033] like Figure 3 to Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the outer side of the drifting boat 1 is fixed with a fixing frame 101 by bolts, the inside of the fixing frame 101 is tightly pressed with an inflatable rod 102, the top of the drifting boat 1 is penetrated with a water inlet 103, the top of the drifting boat 1 is fixed with an anchor 205 by welding, the top of the support frame 2 is fixedly connected with a fixing rod 201, the inside of the fixing rod 201 is rotatably connected with a collecting wheel 202, the connecting rope 204 is used for objects at both ends, the top of the cavity of the cleaning box 3 is fixedly connected with a sludge suction box 303, and the first connecting pipe 304 is used to collect the inside of the sludge suction boxes 303 at both ends. The silt is collected by a filter box 301 on the outside of the first connecting pipe 304, and a separator 302 is slidably connected to the cavity of the filter box 301. The top of the filter box 301 is fixedly connected to a protective shell 503, and the inside of the protective shell 503 is rotatably connected to a vertical ground dragon 501. The top of the protective shell 503 is sleeved with a second connecting pipe 5, and the top of the second connecting pipe 5 is fixedly connected to a water filter pipe 502. The outside of the water filter pipe 502 is provided with a plurality of groups of circular holes for drainage, so that the water inside the silt can be discharged through the water filter pipe 502 at the top. Finally, the silt is discharged to the top of the drifting boat 1 and discharged to the shore for collection.

[0034] In this embodiment, one end of the connecting rope 204 is connected to the outside of the anchor 205, and the other end of the connecting rope 204 is wrapped around the outside of the collecting wheel 202. The collecting wheel 202 is inserted into the inside of the fixing rod 201, and the connecting rope 204 is fixedly sleeved on the outside of the anchor 205 at the top of the drifting boat 1. When the handle 203 on the outside of the collecting wheel 202 is rotated, the connecting rope 204 pulls the drifting boat 1 toward the shore, and the silt is absorbed into the inside of the sludge suction box 303 at the top of the cavity of the cleaning box 3, and is transmitted to the inside of the separator 302 inside the filter box 301 through the first connecting pipe 304. At this time, the separator 302 separates the silt from the sewage, and the silt diverted from the separator 302 flows to the inside of the protective shell 503, and is squeezed into blocks by the vertical ground dragon 501. At this time, the water inside the silt is discharged through the water filter pipe 502 at the top.

[0035] The working principle of this utility model:

[0036] First, the staff fills the inflatable rod 102 with gas and installs it on the outside of the drifting boat 1 through the fixing frame 101, and then places the drifting boat 1 on the river bank. One end of the connecting rope 204 is connected to the outside of the anchor 205, and the other end of the connecting rope 204 is wound around the outside of the collecting wheel 202. The collecting wheel 202 is inserted into the fixing rod 201, and the connecting rope 204 is fixedly sleeved on the outside of the anchor 205 at the top of the drifting boat 1. When the handle 203 on the outside of the collecting wheel 202 is turned, the connecting rope 204 pulls the drifting boat 1 toward the shore.

[0037] When dredging is required, water is added to the water inlet 103 at the top of the drifting boat 1. At this time, the drifting boat 1 floats toward the water surface and sinks the cleaning box 3 to the river bottom. At this time, the rotating rod 405 inside the cleaning box 3 drives the rotating stick 4 on the outside to approach the silt on the river bottom. At this time, the rotary tillage blade 401 on the outside of the rotating stick 4 scrapes the silt and transmits it to the outside of the horizontal stripe dragon 404. At this time, the silt is adsorbed into the interior of the sludge suction box 303 at the top of the cavity of the cleaning box 3, and is transmitted to the interior of the separator 302 inside the filter box 301 through the first connecting pipe 304. At this time, the separator 302 separates the silt from the sewage, and the silt diverted from the separator 302 flows to the interior of the protective shell 503 and is squeezed into blocks by the vertical stripe dragon 501. At this time, the water inside the silt is discharged through the water filter pipe 502 at the top. Finally, the silt is discharged to the top of the drifting boat 1 and discharged to the shore for collection.

[0038] 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.
