Description

Technical Field

[0001] The utility model relates to the technical field of river channels, in particular to a device for cleaning and compressing silt at the bottom of a river channel. Background Art

[0002] A river channel refers to a naturally formed or artificially excavated waterway with a certain width, depth and flow. It is usually a channel for rivers or streams to flow in the terrain. Silt will be left at the bottom of the river channel and needs to be removed by a cleaning device. The silt cleaning and compression device is a device used to treat silt and bottom sediment in rivers, lakes, ports and other waters. By cleaning and compressing the silt, the water and air in the bottom sediment are discharged, the volume of the silt is reduced, the pollution of the water body by the silt is reduced, and the water quality is improved.

[0003] In the prior art, a Chinese patent with authorization announcement number CN218148589U discloses a river channel dredging device that can compress silt, which belongs to the field of river channels. Its technical points include a base, a treatment box is installed on the top of the base, and a water filtering mechanism is installed inside the treatment box. The water filtering mechanism includes a filter plate, a guide groove, an electric push rod, a filter press plate, a filter screen, a wastewater pipe, a box door and an observation window. The filter press plate will squeeze the silt on the filter plate and squeeze out the river water in the silt. The squeezed river water will flow out through the guide groove and fall to the bottom of the inner wall of the treatment box, and finally be discharged through the wastewater pipe. The squeezed silt has a smaller volume, which solves the problem that the silt is currently pumped out of the river channel using a silt pump. When the silt is pumped out, a large amount of river water will be carried, resulting in a large volume of silt and difficult storage.

[0004] At present, most sludge cleaning devices on the market still have certain deficiencies when used. As shown in the above-mentioned document, the device compresses the volume of sludge through a water filtering mechanism to facilitate the storage of sludge. However, the holes in the filter plate are easily clogged when filtering sludge. When clogged, water cannot flow, affecting the compression efficiency. Secondly, the bumps and vibrations generated by the cleaning device during transportation can easily cause damage to internal parts. There is no good buffering effect, which affects the service life of the device and has certain deficiencies in use. Utility Model Content

[0030] It includes a storage box 1, a support leg 2 is fixed at the bottom of the storage box 1, a pressurizing device 3 is installed on the left side of the storage box 1, a sludge pump 4 is installed on the top of the storage box 1, a water outlet 5 is connected to the bottom of the storage box 1, an extrusion plate 6 is connected inside the storage box 1, a buffer mechanism for improving the transportation stability of the sludge cleaning and compression device is arranged inside the support leg 2, an extrusion groove 201 is opened at the bottom of the support leg 2, the extrusion groove 201 is connected to a second spring 202, a connecting leg 203 is connected to the bottom end of the second spring 202, a limiting groove 204 is symmetrically opened on the side of the connecting leg 203, a limiting block 205 is slidably opened inside the limiting groove 204, the limiting block 205 is fixed inside the extrusion groove 201, a telescopic groove 601 is opened on the side of the extrusion plate 6, a dredging mechanism is arranged inside the telescopic groove 601 to prevent the water filter plate 7 from being blocked, the extrusion groove 201 is slidably connected to the connecting leg 203, the limiting groove 204 is slidably connected to the limiting block 205, and the limiting block 205 and the support leg 2 form an integrated structure;

[0031] The sludge cleaning and compression device will vibrate during transportation. When the device vibrates, the supporting leg 2 can drive the extrusion groove 201 and the limit block 205 to move. When the limit block 205 slides, it can slide through the limit groove 204. When the extrusion groove 201 moves, it can slide through the connecting leg 203. When the extrusion groove 201 slides, it can squeeze the second spring 202. When the second spring 202 is squeezed, it can deform through its own material. When the second spring 202 is deformed, a reaction force can be generated. The reaction force can reduce the impact force generated by the vibration of the supporting leg 2. When the vibration impact is reduced, the wear of components caused by transportation can be reduced, thereby improving the protection of the device and indirectly increasing the service life of the device.

[0032] Embodiment 2:

[0033] like Figure 4 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the buffer mechanism of the sludge cleaning and compression device is not strong enough and cannot well protect the internal components, on the basis of the first embodiment, an extrusion mechanism is disclosed:

During the transportation process of the sludge cleaning and compression device, the limiting block 205 can slide through the limiting groove 204, and the limiting block 205 can be squeezed when it slides to the top of the airbag 206. When the airbag 206 is squeezed, it can be deformed and the internal gas can be discharged, and the gas in the airbag 206 can pass through The gas is transported to the inside of the extrusion air cushion 207 through the air pipe 208. The extrusion air cushion 207 can expand after receiving the gas. When the extrusion air cushion 207 expands, it can squeeze the inner wall of the extrusion groove 201. As the deformation degree of the airbag 206 increases, the extrusion air cushion 207 will also increase the extrusion force. When the inside of the extrusion groove 201 is squeezed, the sliding speed can be reduced, thereby further reducing the vibration impact generated by the support leg 2. At the same time, the extrusion of the extrusion air cushion 207 can prevent the support leg 2 from elastically vibrating under the elastic force of the second spring 202, thereby improving the protection of the support leg 2 during transportation.
