Abstract
Description
Technical Field
[0001] The present application relates to the field of river management, and more specifically, to a device for dredging and restoring the ecological environment of a water conservancy river. Background Art
[0002] River dredging generally refers to the management of rivers, which is a water conservancy project. Through mechanical equipment, the silt deposited on the riverbed is blown and stirred into turbid water, which flows away with the river water, thus playing a role in dredging. River siltation has increasingly affected the normal functioning of flood control, drainage, irrigation, water supply, navigation and other functions. In order to restore the normal functions of rivers and promote the rapid and sustainable development of the economy and society, river dredging projects are carried out.
[0003] When cleaning the silt at the bottom of the river channel, the silt at the bottom of the river channel is sucked up by sludge suction equipment. However, a large amount of sand and gravel particles are mixed in the silt. Since the sucked silt can be reused, it is necessary to separate the unnecessary sand and gravel particles in the silt. The existing separation method is to separate the silt from the sand and gravel particles through a filter. However, the silt has a certain viscosity, which makes the separation and filtration less than ideal. For this reason, we propose a dredging device for water conservancy river ecological restoration. Utility Model Content

Specifically, during the process of water conservancy river channel management, it is necessary to clean the silt accumulated at the bottom of the river channel, move the vehicle body 10 to one side of the river channel, and then start the mud suction mechanism 30, so that the mud suction mechanism 30 sucks the silt at the bottom of the river channel and discharges the silt into the box body 20, and the flushing mechanism 60 is connected with the existing water conveying device, so that the flushing mechanism 60 discharges water to the filtering mechanism 40, and at the same time, the spiral pushing mechanism 50 pushes the sand and gravel filtered on the filtering mechanism 40 to move, so as to separate the silt from the sand and gravel.
[0022] See also Figure 2 The mud suction mechanism 30 includes a mud suction pump 310 installed on the top of the vehicle body 10. The inlet end of the mud suction pump 310 is connected to a mud suction pipe 320, and the outlet end is connected to a mud discharge pipe 330. When set, the mud suction pipe 320 is dragged into the river channel, and suction is generated by the mud suction pump 310, so that the mud suction pipe 320 absorbs the silt at the bottom of the river channel and discharges the silt into the box 20 through the mud discharge pipe 330.
[0023] See also Figure 2The filtering mechanism 40 includes two partitions 410 fixedly mounted on the inner wall of the box body 20, one end of the two partitions 410 are tilted downward, and the tilted ends are fixedly connected to the same semicircular filter plate 420, and the spiral pushing mechanism 50 is located in the semicircular filter plate 420. It should be noted that the sludge is discharged to one side of the semicircular filter plate 420 through the mud outlet pipe 330, and is pushed to the other side by the spiral pushing mechanism 50 in the semicircular filter plate 420, and in the process of pushing the sludge, the sludge is filtered through the semicircular filter plate 420, and the sludge flows downward through the semicircular filter plate 420, while the sand and gravel stay on the semicircular filter plate 420, and are pushed and discharged to the outside of the box body 20 by the spiral pushing mechanism 50.
[0024] See also Figure 1 A crushed stone discharge outlet 210 is provided on the side wall at one end of the box body 20, and the crushed stone discharge outlet 210 is arranged corresponding to the semicircular filter plate 420. A first pouring plate 220 located below the crushed stone discharge outlet 210 is installed on the outer wall of the box body 20, and an inclined guide plate 230 is installed on the inner wall of the box body 20, and a sludge discharge outlet 240 located at the bottom of the guide plate 230 is provided on its side wall. A second pouring plate 250 located below the sludge discharge outlet 240 is also installed on the outer wall of the box body 20. When set, the crushed stone is discharged from the crushed stone discharge outlet 210 to the first pouring plate 220, so that the crushed stone rolls downward on the first pouring plate 220, and the sludge will fall onto the inclined guide plate 230 after passing through the semicircular filter plate 420, and flow downward along the guide plate 230 to the sludge discharge outlet 240, and be discharged from the sludge discharge outlet 240 to the second pouring plate 250.
[0025] See also Figure 2 The spiral pushing mechanism 50 includes a motor 510 installed on the outer wall of the box body 20. The driving shaft of the motor 510 is connected to a spiral push rod 520 that rotates and passes through the side wall of the box body 20. The spiral push rod 520 is located in the semicircular filter plate 420. It should be noted that a support plate is fixedly installed on the outer wall of the box body 20, and the motor 510 is installed on the support plate. The motor 510 drives the spiral push rod 520 to rotate to push the sludge to move on the semicircular filter plate 420.
[0026] See also Figure 4 The flushing mechanism 60 includes a bracket 610 fixedly mounted on the top of the box body 20, a water pipe 620 is installed on the top of the bracket 610, and the bottom of the water pipe 620 is connected to a plurality of nozzles 630, and the plurality of nozzles 630 are all located above the spiral push rod 520. Furthermore, the water pipe 620 is connected to an existing water delivery device, so that water passes through the water pipe 620 and is sprayed from the plurality of nozzles 630 into the box body 20, so that the water enters the semicircular filter plate 420 to dilute the sludge, thereby facilitating the sludge to pass through the semicircular filter plate 420.
[0027] When the present water conservancy river ecological restoration and dredging device is working: the vehicle body 10 is moved to the riverside, and then the mud suction pipe 320 is pushed to the bottom of the river, and the mud suction pump 310 is started. The specific mud suction process is the existing technology, so that the sucked sludge is discharged into the box body 20 through the mud discharge pipe 330. At this time, the motor 510 is started, and water is transported into the water pipe 620 at the same time, and the sludge falls into the semicircular filter plate 420. The motor 510 drives the spiral push rod 520 to move in the semicircular filter plate 420 to push the sludge to move in the semicircular filter plate 420. At the same time, a number of nozzles 630 spray water into the semicircular filter plate 420, which can dilute the sludge, so that the sludge passes through the semicircular filter plate 420 and flows downward to be discharged from the box body 20, while the sand and gravel are filtered on the semicircular filter plate 420 and pushed out of the box body 20 by the spiral push rod 520, so as to achieve the purpose of separating the sludge from the sandpaper.
