[0001] The present invention belongs to the technical field of dredging in water conservancy projects, and specifically relates to a portable operation device for dredging planning in water conservancy projects. Background Art

[0002] A water conservancy project is a project built to eliminate water disasters and develop and utilize water resources. According to its service objects, it is divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, beach reclamation projects, etc. A water conservancy project that can serve multiple objectives such as flood control, water supply, irrigation, and power generation at the same time is called a comprehensive utilization water conservancy project.

[0003] A patent with the publication number CN216664289U discloses a portable operation device for dredging planning in water conservancy projects. A portable operation device for dredging planning in water conservancy projects, characterized in that it includes: a dredging box; an observation device fixedly installed on one side of the dredging box; an adjusting device arranged on the top of the dredging box, the adjusting device includes a first mounting block, a first rotating shaft is arranged in the middle on one side of the first mounting block, a telescopic cylinder is arranged in the middle on the outer surface of the first rotating shaft, one end of the output shaft of the telescopic cylinder is provided with a second rotating shaft, and second mounting blocks are arranged on both sides of the second rotating shaft. A portable operation device for dredging planning in water conservancy projects adjusts the position of the camera through the movement of the output shaft of the telescopic cylinder, so that the camera can observe the environment inside the bottom of the water, allowing the operator to observe the position of the silt at the bottom and control the movement of the dredging box to perform dredging operations on the silt at the bottom, with convenient operation.

[0004] In the current prior art, when existing water conservancy projects carry out silt cleaning, many use excavators or dredgers for silt cleaning.

Detailed implementation manners

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0029] Such as Figures 1 to 4As shown in the figure, a portable operating device for dredging in a water conservancy project planning according to an embodiment of the present invention includes a mobile vehicle 11 and a swing arm 12 detachably installed on the top surface of the mobile vehicle 11, a sludge scraping box 13 detachably installed on the outer surface of the swing arm 12, a sludge pressing box 14 detachably installed on the outer surface of the swing arm 12 and located at the top edge position of the mobile vehicle 11. A slider 123 is provided on the outer bottom surface of the swing arm 12. A swing arm 124 is swingably connected to the bottom surface of the slider 123. Grooves are formed on both side surfaces of the swing arm 124 and located at the bottom edge position. A double-strand support rod 125 is fixedly connected to the inner side wall surface of the groove. A slider 126 is movably sleeved on the outer surface of the double-strand support rod 125. A swing arm 127 wrapped around the outer surface of the swing arm 124 is movably sleeved on one side surface of the slider 126. One end of the swing arm 127 is swingably sleeved on the top surface of the sludge scraping box 13. A sludge suction pipe 128 is fixedly connected to the top surface of the sludge scraping box 13. The other end of the sludge suction pipe 128 is fixedly connected to the receiving end of the sludge pressing box 14. A motor 121 is fixedly installed on the inner side wall surface of the swing arm 12. A limiting rod 122 is fixedly connected to the inner side wall surface of the swing arm 12 and located at one side edge position of the motor 121. The inner side wall surface of the slider 123 is movably sleeved on the output end of the motor 121 and the outer surface of the limiting rod 122. The outer surface of the sludge suction pipe 128 is arranged on the outer surface of the slider 123. A lapping platform 111 is fixedly connected to the top surface of the mobile vehicle 11. The bottom surface of the swing arm 12 is movably lapped on the top surface of the lapping platform 111. A filter water tank 112 is fixedly installed on the top surface of the mobile vehicle 11. A rotating shaft 113 is fixedly installed on the top surface of the mobile vehicle 11 and located at one side edge position of the filter water tank 112. The output end of the rotating shaft 113 is arranged on the bottom surface of the swing arm 12.

[0030] The mobile vehicle 11 is used to move and transport the swing arm 12, and the rotating shaft 113 is used to rotate the swing arm 12 so that the swing arm 12 spans across the water conservancy river. At this time, the swing arm 124 swings downward on the bottom surface of the slider 123. According to the depth of the river, the slider 126 moves downward on the surface of the double-strand support rod 125, and the sludge scraping box 13 is completely immersed in the water, so that the bottom surface of the sludge scraping box 13 is lapped on the river sludge. Employees can hold the other end of the swing arm 127 and lift the surface of the sludge scraping box 13 up and down with the slider 126 as the center point, which can manually fit and adjust the depth of the sludge in the river, achieving the effect of autonomously adjusting the height for rivers with different depths and manually swinging and squeezing the thicker sludge during sludge cleaning.

[0031] Such as Figure 1 -Figure 3 and Figures 7 to 8 As shown in Figures 7 to 8 , a second motor 131 is fixedly installed on one side surface of the sludge scraping box 13. Two groups of transmission rods 132 are movably sleeved on the outer surface of the sludge scraping box 13. A transmission gear 133 that is movably lapped on the outer surface of the sludge scraping box 13 is fixedly connected to the outer surface of one end of the transmission rod 132. The outer surface of the output end of the second motor 131 is movably lapped on the outer surface of the transmission gear 133. A first fixing plate 134 is arranged on the outer surface of the two groups of transmission rods 132 and inside the sludge scraping box 13. A crushing claw 135 is fixedly connected to one side surface of the first fixing plate 134.

[0032] At this time, in cooperation with the rotation of the second motor 131, the output end of the second motor 131 drives the transmission gear 133 on the outer surface of the transmission rod 132 to rotate oppositely on the inner wall surface of the sludge scraping box 13. During the rotation of the transmission rod 132, the crushing claws 135 on the outer surface of the first fixing plate 134 cooperate to grab the sludge and some solid branches deep in the river channel, and through the opposite crossing between the two groups of crushing claws 135, the excavated sludge and branches are crushed. The crushed sludge will diffuse out through the gaps on the surface of the first fixing plate 134. At this time, through the narrow space inside the sludge scraping box 13, the crushed sludge is preliminarily concentrated. At this time, the inside of the sludge scraping box 13 is pumped with sewage through the sludge suction pipe 128. While pumping the sewage, the sludge inside the sludge scraping box 13 will be absorbed and discharged together. By using the narrow space inside the sludge scraping box 13 to increase the suction force of the sludge suction pipe 128, the suction force of the sludge suction pipe 128 can be increased by using the narrow space inside the sludge scraping box 13. The sewage will continuously spread upward from the bottom of the first fixing plate 134. Under the continuous flow of the sewage, the sludge blocks remaining in the sewage can be pushed up, and at the same time, the sludge remaining inside the first fixing plate 134 can be flushed.

[0033] As Figures 5 to 6As shown in the figure, a filter inclined plate 141 is fixedly connected to the inner wall surface of the sludge pressing box 14. A sludge inlet hole 142 that wraps around the outer surface of one end of the sludge suction pipe 128 is formed on one side surface of the sludge pressing box 14. A rolling roller 144 and a sludge pushing roller 146, which are arranged on the outer surface of the top of the filter inclined plate 141, are movably sleeved on the inner wall surface of the sludge pressing box 14. A sludge scraping plate 145 that is movably lapped on the top surface of the rolling roller 144 is fixedly connected to the inner wall surface of the sludge pressing box 14. A mud baffle 143 that is arranged on the outer surface of the sludge inlet hole 142 is fixedly connected to the inner top wall surface of the sludge pressing box 14. A second fixing plate 147 is fixedly connected to the back surface of the sludge pressing box 14. A third motor 148 is fixedly installed on the inner wall surface of the second fixing plate 147. The output end of the third motor 148 is fixedly connected to the outer surface of one end of the rolling roller 144. A toothed hole type crawler belt 149, which is respectively arranged on the outer surface of one end of the sludge pushing roller 146, is movably sleeved on the outer surface of the output end of the third motor 148. A water filtering and sludge guiding plate a1 is fixedly connected to the inner wall surface of the water filtering tank 112. A sludge discharge port a2 is formed on one side surface of the water filtering tank 112 and at the bottom end position of the water filtering and sludge guiding plate a1. A water guiding plate a3, which is arranged on the bottom surface of the water filtering and sludge guiding plate a1, is fixedly connected to the inner bottom wall surface of the water filtering tank 112.

[0034] When the sewage carries sludge into the inside of the sludge pressing box 14, the mud baffle 143 is used to block the fast-flowing water source to reduce the impact of the water source. At this time, the filter inclined plate 141 is used to filter the water source preferentially. Then, the third motor 148 rotates the rolling roller 144. The rolling roller 144 is used to roll the sludge on the top surface of the filter inclined plate 141. The rolled sewage will pass through the filter inclined plate 141 and enter the inside of the water filtering tank 112, and the water guiding plate a3 is used to redirect the sewage back into the river. As the rolling roller 144 continues to rotate, the sludge scraping plate 145 is used to scrape off some remaining sludge. During the transmission process of the third motor 148, the toothed hole type crawler belt 149 and the sludge pushing roller 146 are driven to rotate together. When the sludge pushing roller 146 rotates, the rolled and dried sludge is pushed to the bottom layer and discharged into the sludge collection vehicle through the sludge discharge port a2.

[0035] Working principle: Cooperate with the mobile vehicle 11 to move and transport the first swing arm 12, and enable the rotating shaft 113 to rotate the first swing arm 12, and make the first swing arm 12 span across the water conservancy river channel. At this time, cooperate with the second swing arm 124 to swing downward on the bottom surface of the first slider 123. According to the depth of the river channel, cooperate with the second slider 126 to move downward on the surface of the double-strut support rod 125, and make the sludge scraping box 13 completely immersed in the water, so that the bottom surface of the sludge scraping box 13 is lapped on the river channel sludge. And the employee can hold the other end of the third swing arm 127 and, with the second slider 126 as the center point, lift the surface of the sludge scraping box 13 up and down, so as to manually fit and adjust the depth of the sludge in the river channel, achieving the effect of autonomously adjusting the height for river channels of different depths. When cleaning the sludge, the sludge at the thicker part can be manually swung and squeezed for cleaning;

[0036] At this time, cooperate with the second motor 131 to rotate, so that the output end of the second motor 131 drives the transmission cogs 133 on the outer surface of the transmission rod 132 to rotate oppositely on the inner wall surface of the sludge scraping box 13. During the rotation of the transmission rod 132, cooperate with the crushing claws 135 on the outer surface of the first fixing plate 134 to grab the sludge and some solid branches deep in the river channel, and through the opposite crossing between the two groups of crushing claws 135, crush the excavated sludge and branches. The crushed sludge will diffuse out through the gaps on the surface of the first fixing plate 134. At this time, through the narrow space inside the sludge scraping box 13, the crushed sludge is preliminarily concentrated. At this time, cooperate with the sludge suction pipe 128 to pump sewage inside the sludge scraping box 13. While pumping sewage, the sludge inside the sludge scraping box 13 will be absorbed and discharged together. By using the narrow space inside the sludge scraping box 13 to increase the suction of the sludge suction pipe 128, the effect of increasing the extraction force of the sludge suction pipe 128 by using the narrow space inside the sludge scraping box 13 is achieved. And the sewage will continuously spread upward from the bottom of the first fixing plate 134. Under the continuous flow of the sewage, the sludge blocks remaining in the sewage can be pushed up, and at the same time, the sludge remaining inside the first fixing plate 134 can be washed;
