Description

Technical Field

[0001] The invention relates to a silt removing device, in particular to a hanging type river channel silt removing device. Background Art

[0002] River ecological restoration refers to the use of ecosystem principles and various methods to repair the biological communities and structures of damaged water ecosystems, rebuild healthy aquatic ecosystems, repair and strengthen the main functions of water ecosystems, and enable the ecosystem to achieve a virtuous cycle of overall coordination, self-sustaining and self-succession. Among them, clearing river silt is one of the means of river ecological restoration, which can restore the water to clarity and the ecosystem within the river.

[0003] Scouring and silting often occur in natural rivers, causing water disasters and hindering the development of water conservancy. In order to meet the requirements of eliminating hazards and promoting benefits, projects including guidance, dredging and bank protection are usually adopted to regulate the river channel. The silt cleaning at the bottom of the river channel is a difficult point to manage. In the prior art, river channel silt cleaning is generally selected in the dry season of the river, and then the river section that needs to be cleaned is intercepted to prevent the water from entering the cleaning section, and finally the silt in the river section is dug out by equipment such as excavators. However, the inventor found that this method is subject to seasonal restrictions when silting. When the dry season ends early, if the river channel silt is not cleaned in time, the silt cleaning project will be forced to end early without achieving the expected effect, thereby affecting the ecological restoration effect of the river channel; however, due to the long-term accumulation of silt in the river channel, the silt is condensed into blocks. When the silt cleaning device is working, large pieces of silt cannot be pumped out by pumps, thereby blocking the pipeline and damaging the equipment. In view of this, the present invention designs a hanging river channel silt removal device. Summary of the invention

[0017] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0018] (i) In the present application, a top crane with a lifting point is placed in the river channel, so that the cleaning box and the collecting box are moved down until they are deep in the silt at the bottom of the river. The dual-axis motor drives the two active rods to rotate, so that the active rods drive the mounting plate and the silt bucket to rotate. The silt enters the distribution bin through the silt inlet. Each silt bucket scoops the incoming silt and pours it into the tilting bucket, and finally flows into the collecting bin. On the one hand, it avoids the accumulation of silt in the distribution bin and causes the silt inlet to be blocked. On the other hand, the silt can be stirred and transported to make dredging smoother.

[0019] (ii) In the present application, during the rotation of the sludge bucket, since a second magnetic piece that magnetically repels the first magnetic piece is installed on the outer side of the sludge bucket, when the sludge bucket closest to the sludge inlet swings to a horizontal state, the magnetic repulsion between the first magnetic piece and the second magnetic piece is maximum. At this time, the reset spring is compressed, causing the movable plate to drive the conductive block to move until the conductive block contacts the piezoelectric seat and the electric telescopic rod is energized and turned on. The electric telescopic rod drives the sealing plate to contract to release the blockage of the sludge inlet, thereby allowing the sludge to flow into the sludge bucket, thereby utilizing all the inflowing sludge to a greater extent and avoiding the accumulation of sludge in the distribution bin.

[0020] (III) In the present application, during silt removal, due to the meshing of the first bevel gear and the second bevel gear, the driven rod rotates together with the active rod, that is, the scattering impeller rotates, and at the same time, the cleaning box is moved to disperse the riverbed silt, making it easier for it to enter through the silt inlet, and to avoid blockage caused by large pieces of silt, which may be stuck in the silt bucket. Matrix rods are arranged around the scattering impeller to provide enclosure protection for it. The matrix rods can remove hard debris to avoid damage to the scattering impeller, and can drive away fish in the silt to avoid damage to the impeller. The scattering impeller is suitable for dredging projects in rivers during dry seasons and non-dry seasons, so that its work is not limited by season.

[0021] (IV) In the present application, during the dredging process, the external servo motor drives the Z-axis screw to rotate, so that the work-type slide and the support frame drive the cleaning box to move up and down, so that it can remove silt of different depths and can adapt to different types of rivers, with better adaptability.

[0022] (V) In the present application, during the process of hoisting the cleaning box and the collecting box, the electric telescopic rod drives the blocking plate to move downward, so that the blocking plate blocks the sludge entrance, preventing river water from entering the distribution bin and the collecting bin before dredging, thereby ensuring the utilization rate of the space.

The output end of the electric telescopic rod 10 is fixedly connected to the sealing plate 11. The size of the sealing plate 11 is larger than the size of the sludge inlet 5. The sealing plate 11 covers the sludge inlet 5.

[0051] In this embodiment: the top seat 3 with the lifting point is lifted by an external lifting device. When the cleaning box 1 and the collecting box 4 are lifted, the electric telescopic rod 10 drives the blocking plate 11 to move downward, so that the blocking plate 11 blocks the sludge inlet 5, preventing the river water from entering the distribution bin 41 and the collecting bin 42 before dredging, thereby ensuring the utilization rate of the space;

[0052] During the rotation of the sludge bucket 9, since the second magnetic piece 17 that magnetically repels the first magnetic piece 16 is installed on the outer side of the sludge bucket 9, when the sludge bucket 9 closest to the sludge inlet 5 swings to a horizontal state, the magnetic repulsion between the first magnetic piece 16 and the second magnetic piece 17 is the largest. At this time, the reset spring 13 is compressed, causing the movable plate to drive the conductive block 14 to move until the conductive block 14 contacts the piezoelectric seat 15 and the electric telescopic rod 10 is energized and turned on. The electric telescopic rod 10 drives the sealing plate 11 to contract to release the blockage of the sludge inlet 5, and then allows the sludge to flow into the sludge bucket 9, thereby utilizing all the incoming sludge to a greater extent and avoiding the sludge from accumulating in the distribution bin 41.

[0056] The overall working principle of the present invention is as follows: the top seat 3 with the hanging point is hung in the river channel, and the cleaning box 1 and the collecting box 4 are moved down until they are deep in the silt at the bottom of the river. The dual-axis motor 19 drives the two active rods 7 to rotate, so that the active rods 7 drive the mounting plate 8 and the silt bucket 9 to rotate, and the silt enters the distribution bin 41 through the silt inlet 5.

At this time, the reset spring 13 is compressed, so that the movable plate drives the conductive block 14 to move until the conductive block 14 contacts the piezoelectric seat 15 and the electric telescopic rod 10 is powered on, and the electric telescopic rod 10 drives the blocking plate 11 to contract to release the blockage of the sludge inlet 5, and then the sludge flows into the sludge bucket 9, and all the inflowing sludge is used to a higher degree to avoid the sludge from accumulating in the distribution bin 41.

[0059] During silt removal, due to the meshing of the first bevel gear 2201 and the second bevel gear 701, the driven rod 22 rotates together with the active rod 7, that is, the scattering impeller 23 rotates, and at the same time, the cleaning box 1 is moved to disperse the riverbed silt, making it easier for it to enter through the silt inlet 5, and to avoid blockage caused by large pieces of silt, or even stuck in the silt bucket 9.
