Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-6As shown in the figure, a river dredging device includes a support base 1 and support feet 2. On the outer wall of the bottom end of the support base 1, two groups of support feet 2 are symmetrically arranged. Above the support base 1, there is a dredging control mechanism 3 for pumping silt, and above the support base 1, there is a portable installation mechanism 4 for fixing a silt storage box. Above the portable installation mechanism 4, there is a drainage control mechanism 5 for squeezing the accumulated water in the silt. The dredging control mechanism 3 includes an annular support base 31, a silt pump 32, a feed pipe 33, a discharge pipe 34, and a guide pipe 35. On the outer wall of the top end of the support base 1, there is an annular support base 31. On the outer wall of the top end of the annular support base 31, there is a silt pump 32. At the bottom end of the silt pump 32, a feed pipe 33 is installed, and the feed end of the feed pipe 33 is arranged below the support base 1. On the side of the silt pump 32, there is a discharge pipe 34, and a guide pipe 35 is installed on the side of the discharge pipe 34 through a flange. When the device is in use, a suction pipe needs to be installed at the bottom end of the feed pipe 33 according to the distance of the actual silt suction position point. Then, the suction pipe is inserted into the silt layer to be pumped, and the silt pump 32 is started. When the silt pump 32 operates normally after being started, the silt will automatically be transported through the external suction pipe to the inside of the feed pipe 33, and then through the discharge pipe 34 and the guide pipe 35 to the inside of the following collection box 41. Here, the guide plate 42 arranged on the side of the collection box 41 has a guiding effect on the silt.

[0024] The portable installation mechanism 4 includes a collection box 41, a guide plate 42, and a limit handle 43. The collection box 41 is attached to the outer wall of the top end of the support base 1. On the outer wall of the collection box 41 facing the guide pipe 35, there is a guide plate 42. On the outer walls of both sides of the collection box 41, two limit handles 43 are symmetrically arranged. On the outer wall of the bottom end of the collection box 41, two groups of contact posts 44 are symmetrically arranged. On the outer wall of the top end of the support base 1, two groups of contact slots 45 are symmetrically opened. The contact posts 44 and the contact slots 45 are installed in a snap-fit manner. When the collection box 41 needs to be installed above the support base 1, first, two limit handles 43 need to be held to lift the collection box 41. Then, after adjusting the collection box 41 to the appropriate position, the contact posts 44 at its bottom end are snapped into the contact slots 45 at the corresponding positions to complete the installation. The removal is the same.

[0025] The drainage control mechanism 5 includes a positioning mounting frame 51, a cylinder 52 and a pressing plate 53. The positioning mounting frame 51 is provided on the outer wall of the top end of the support base 1. The cylinder 52 is provided on the inner wall of the bottom end of the positioning mounting frame 51. The output end of the cylinder 52 is connected to the outer wall of the top end of the pressing plate 53. The pressing plate 53 is slidably installed between the side inner walls of the collection box 41. When there is a large amount of silt accumulation in the collection box 41 and it is necessary to squeeze out the accumulated water inside to store the subsequent silt, at this time, only the cylinder 52 needs to be turned on. After the cylinder 52 is turned on, its output end automatically extends downward and pushes the pressing plate 53 to move downward. When the pressing plate 53 moves into the collection box 41, it will automatically squeeze the silt stored inside. Then, the excess water in the silt will be automatically discharged uniformly through the following placement groove 61. The filter plate 62 provided inside the placement groove 61 here enables the above-mentioned silt not to squeeze out the excess silt during extrusion, and at the same time can ensure that the accumulated water in the silt can be discharged normally. Here, it should be noted that the mesh number of the filter plate 62 cannot be too large, otherwise the silt will be squeezed out.

[0026] The collection box 41 is provided with a placement groove 61 on the outer wall of the side at the bottom end. A filter plate 62 is provided inside the placement groove 61. Positioning blocks 63 are symmetrically provided on the outer walls on both sides of the filter plate 62. A first threaded groove 64 is penetrated and opened on the outer wall of the side of the positioning block 63. Two groups of positioning slots 65 are symmetrically opened on the outer wall of the side of the collection box 41 at the position of the placement groove 61. The positioning block 63 and the positioning slot 65 are snap-fitted. A second threaded groove 66 is correspondingly opened on the outer wall of the side of the collection box 41 at the position of the positioning slot 65. The first threaded groove 64 and the second threaded groove 66 are threadedly installed with a fastening bolt 67. When it is necessary to remove the filter plate 62 for cleaning after the silt inside the collection box 41 is emptied, at this time, only the fastening bolt 67 needs to be completely screwed out from the inside of the first threaded groove 64. Then, the positioning block 63 changes from the locked state to the movable state. Subsequently, the filter plate 62 together with the positioning block 63 can be directly taken out from the side of the collection box 41. When reinstalling after the filter plate 62 is cleaned, at this time, only the filter plate 62 needs to be adjusted to the appropriate position and then the positioning block 63 on its side is pushed into the positioning slot 65 at the corresponding position. When the positioning block 63 moves to the bottom end of the positioning slot 65, at this time, the positions of the first threaded groove 64 and the second threaded groove 66 are in a corresponding and fitting state. Then, the fastening bolt 67 is directly passed through the first threaded groove 64 and screwed to the bottom end of the second threaded groove 66 to complete the installation.

[0027] When the present utility model is in use, first, the collection box 41 needs to be installed above the support base 1. At this time, first, the two limit handles 43 need to be held to lift the collection box 41. Then, after the collection box 41 is adjusted to the appropriate position, the abutting post 44 at its bottom end can be snapped into the corresponding abutting groove 45 to complete the installation.

[0028] When the device is in use, a pumping pipe needs to be installed at the bottom of the feed pipe 33 according to the distance of the actual sludge pumping position point. Then, the pumping pipe is inserted into the sludge layer to be pumped, and the sludge pump 32 is turned on. When the sludge pump 32 operates normally after being turned on, the sludge will automatically be transported to the inside of the feed pipe 33 through the drainage of the external pumping pipe, and then through the drainage of the discharge pipe 34, it will be sent to the inside of the following collection box 41 through the guide pipe 35. Here, the diversion plate 42 provided on the side of the collection box 41 has a diversion effect on the sludge;

[0029] When there is a lot of sludge accumulated in the collection box 41 and it is necessary to squeeze out the accumulated water inside to store the subsequent sludge, only the air cylinder 52 needs to be turned on at this time. After the air cylinder 52 is turned on, its output end automatically extends downward and pushes the pressing plate 53 to move downward. When the pressing plate 53 moves into the collection box 41, it will automatically squeeze the sludge stored inside. Then, the excess water in the sludge will automatically be discharged uniformly through the following placement groove 61. Here, the filter plate 62 provided inside the placement groove 61 enables the above-mentioned sludge not to squeeze out the excess sludge during extrusion, and at the same time can ensure that the accumulated water in the sludge can be discharged normally. It should be noted here that the mesh number of the filter plate 62 cannot be too large, otherwise the sludge will be squeezed out. It is noted here that when squeezing the sludge, the sludge pump 32 needs to be turned off, otherwise the sludge will be discharged outside the collection box 41;

[0030] When the sludge in the collection box 41 is emptied and the filter plate 62 needs to be removed for cleaning, only the fastening bolt 67 needs to be completely screwed out from the inside of the first thread groove 64 at this time. Then, the positioning block 63 changes from the locked state to the movable state. Subsequently, the filter plate 62 together with the positioning block 63 can be directly taken out from the side of the collection box 41. When reinstalling the filter plate 62 after cleaning, only the filter plate 62 needs to be adjusted to the appropriate position and then the positioning block 63 on its side is pushed into the positioning slot 65 at the corresponding position. When the positioning block 63 moves to the bottom end of the positioning slot 65, the positions of the first thread groove 64 and the second thread groove 66 are in a corresponding and fitting state. Then, the fastening bolt 67 is directly passed through the first thread groove 64 and screwed to the bottom end of the second thread groove 66 to complete the installation.

[0031] It is noted here that the above-mentioned air cylinder 52 can be powered according to the existing operation technical means. Whether it is powered by a power supply component or an external wire, it belongs to the existing conventional operation technical means and will not be described in detail here.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
