[0002] With the development of society and the continuous improvement of urban industrialization levels, rivers have become increasingly polluted. There are large amounts of floating objects such as industrial waste and domestic waste in the rivers. Long-term accumulation will seriously affect the river environment and cause serious pollution to the rivers. If they are not cleaned up in a timely manner, large amounts of accumulation will cause blockages in the rivers. At present, rivers are seriously polluted, and there is often floating garbage in the rivers, such as plastic bags, beverage bottles and other surface garbage.

The garbage salvage mechanism picks up the garbage and slides it into the garbage guide frame, and transports it to the garbage drop port through the garbage conveying mechanism to concentrate the garbage. The device can adjust the salvage height through the lifting fixed frame; the direction of the garbage collection port on the garbage guide frame can also be adjusted through the angle fixing bolt group to adapt to the supporting environment of the supporting frame in the river channel, and the salvage plate groove can also be cleaned by the salvage plate groove cleaning device.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0034] refer to Figure 1-Figure 2 A river cleaning device for water conservancy projects includes a symmetrically arranged hull 1, an inverted V-shaped slide rail 2 and a feeding mechanism 3. The lower end outlets of the slide rail 2 correspond to the hulls 1 on both sides. The feeding mechanism 3 is used to collect and transport garbage floating on the river surface and send it to the slide rail 2, and then the debris is sent into the hull 1 through the slide rail 2 for collection.

[0035] refer to Figure 4 A bulkhead three 112 and a bulkhead four 113 are fixedly installed in the hull 1. The bulkhead three 112 and the hull 1 form a cabin one 122. The cabin one 122 serves as the stern of the hull 1 and can be used to install a driving mechanism of the hull 1 to drive the hull 1 forward. The driving mechanism is a prior art and does not need to be described in detail here. A cabin three 124 is formed between the bulkhead three 112 and the bulkhead four 113. The cabin three 124 is used to place collected river garbage. The bulkhead four 113 and the hull 1 form a cabin two 123. The cabin two 123 serves as the head of the hull 1. A telescopic cylinder 13 is fixedly installed inside. The piston rod of the telescopic cylinder 13 penetrates the hull 1 and is slidably fitted.

[0036] refer to Figure 4 and Figure 8A cleaning plate 14 is provided on the outside of the second cabin 123. The garbage on the river surface is collected by the cleaning plates 14 on both sides, so that the garbage can be better entered into the feeding mechanism 3. The surfaces of the cleaning plates 14 opposite to the hull 1 are symmetrically fixed with supports 141, and a fixed shaft 142 is fixedly installed between the two supports 141. A connecting block 143 is slidably provided on the surface of the fixed shaft 142, and the connecting block 143 also slides on the surface of the cleaning plate 14.

[0037] refer to Figure 4 and Figure 8 A connecting block 131 is fixedly installed on the outer end of the piston rod of the telescopic cylinder 13, and the connecting block 131 is hingedly matched with the connecting block 2 143. A connecting plate 15 is fixedly installed on the outer side of the hull 1, and the connecting plate 15 is hingedly matched with one side of the cleaning plate 14 through a hinge.

[0038] Furthermore, the telescopic cylinder 13 pushes the connecting block 131, so that the connecting block 131 pushes the connecting block 2 143 to slide on the surface of the cleaning plate 14 and the surface of the fixed shaft 142, and then the angle between the cleaning plate 14 and the connecting plate 15 is adjusted, and the angle range of the angle is controlled between 90°-180°, excluding 90° and 180°. If the angle is 90° or 180°, the garbage on the river surface cannot smoothly enter between the connecting plates 15.

[0039] Furthermore, when the telescopic cylinder 13 pushes the connecting block 131 away from the hull 1, the angle between the cleaning plate 14 and the connecting plate 15 increases, and the range of collecting river garbage will be correspondingly reduced. This is suitable for the situation where the river is narrow. When the telescopic cylinder 13 drives the connecting block 131 close to the hull 1, the angle between the cleaning plate 14 and the connecting plate 15 decreases, and the range of collecting river garbage will be correspondingly expanded. This is suitable for the situation where the river is wide.

[0040] refer to Figure 2 and Figure 3 The feeding mechanism 3 includes a conveyor belt 31, a bracket 34 and symmetrically arranged rollers 36. The two rollers 36 are rotatably arranged between the upper end of the bracket 34 and the two connecting plates 15. The conveyor belt 31 connects the two rollers 36. The conveyor belt 31 is driven to move by the rotation of the rollers 36, and the conveyor belt 31 is arranged at an angle.

[0041] refer to Figure 2 and Figure 3A plurality of water-permeable holes 32 are provided on the surface of the conveyor belt 31, and the water-permeable holes 32 are used to separate the accompanying river water during the transportation and loading of river garbage. A plurality of neatly arranged support plates 33 are fixedly installed on the surface of the conveyor belt 31, and the support plates 33 can drive the river garbage entering between the two connecting plates 15 through the cleaning plates 14 on both sides to the surface of the conveyor belt 31. A motor 2 35 is fixedly installed on the outer side surface of the upper end of the bracket 34, and the output shaft of the motor 2 35 is fixed to one side of the upper roller shaft 36. The roller shaft 36 is driven to rotate by the motor 2 35, thereby driving the conveyor belt 31 to drive the plurality of support plates 33 to transport and load the collected river garbage.

[0042] refer to Figure 1-Figure 3 A connecting frame 21 is symmetrically welded on the lower surface of the slide rail 2, and the connecting frame 21 is fixed to the hulls 1 on both sides. The upper end height of the slide rail 2 is lower than the upper end height of the conveyor belt 31. The river garbage transported up by the conveyor belt 31 will fall onto the surface of the slide rail 2 after being transported to the highest point, and then slide into the hulls 1 on both sides through the slopes on both sides of the slide rail 2.

[0043] refer to Figure 4 A bulkhead 11 fixed to the hull 1 is arranged on the right side of the bulkhead three 112, and a bulkhead two 111 fixed to the bottom of the cabin three 124 is arranged below the bulkhead one 11. A through groove is reserved between the bulkhead two 111 and the bulkhead three 112. A horizontally arranged placing plate 5 is fixedly installed between the bulkhead one 11 and the bulkhead four 113. An inclined drain plate 52 is fixedly connected to the placing plate 5 below. The left end of the drain plate 52 is fixed to the bulkhead two 111. A plurality of neat rows of water-permeable holes two 51 are provided on the surface of the placing plate 5. The river garbage falling through the slide rail 2 will fall onto the surface of the placing plate 5, and then the accompanying river water will fall onto the drain plate 52 through the water-permeable holes two 51, and then be discharged to the cabin space between the bulkhead two 111 and the bulkhead three 112 through the drain plate 52.

[0044] refer to Figure 4 A filter plate 16 is fixedly installed between the second partition 111 and the third partition 112. The filter holes on the surface of the filter plate 16 are smaller than the second water permeable hole 51. A water pump 61 is fixedly installed in the cabin below the filter plate 16. The water outlet of the water pump 61 is fixedly connected with a drain pipe 6. The drain pipe 6 passes through the filter plate 16 and the buckle 115 fixedly installed on the upper end of the hull 1. The buckle 115 fixes the position of the drain pipe 6. One end of the drain pipe 6 faces the river surface. The river water flowing into the second partition 111 and the third partition 112 can be pumped away from the hull 1 by the water pump 61, thereby reducing the load of the hull 1 and increasing the collection capacity of river surface garbage, thereby improving the efficiency of cleaning the river surface garbage. Embodiment 2:

[0045] refer to Figure 1-Figure 2On the basis of the first embodiment, in order to further improve the garbage collection capacity of the hull 1, a pushing and squeezing mechanism 4 can be provided on the surface of the placement plate 5 to squeeze the river surface garbage so that the surface of the placement plate 5 can accommodate more garbage.

[0046] refer to Figure 2-Figure 5 The pushing and squeezing mechanism 4 includes an L-shaped push plate 1 41 and a push plate 2 42. The L-shaped push plate 1 41 is slidably arranged on the surface of the placing plate 5, and the push plate 2 42 is slidably arranged on the surface of the L-shaped push plate 1 41. One side edge of the L-shaped push plate 1 is arranged in a cutter shape, which can remove the river surface garbage falling into the water-permeable hole 2 51, and the surfaces of the L-shaped push plate 1 41 and the push plate 2 42 are both provided with a plurality of holes for water discharge, so as to further separate the river water from the river surface garbage during the squeezing process, thereby further improving the collection capacity of the hull 1 for the river surface garbage.

[0047] refer to Figure 5-Figure 9 A lead screw 18 is symmetrically rotatably arranged between the partition 11 and the partition 4 113, and a motor 181 whose output shaft is fixed to one end of the lead screw 18 is fixedly installed on the outer side surface of the partition 4 113. A waterproof plate 17 is symmetrically fixedly installed on the inner wall of the hull 1 in the cabin 3 124, and the waterproof plate 17 can cover the lead screw 18 to prevent the river water from contacting the surface of the lead screw 18 during the process of collecting river garbage, causing the lead screw 18 to rust, thereby affecting the transmission effect of the lead screw 18. The surface thread of the lead screw 18 is provided with a sliding block 182 that slides on the inner wall of the hull 1, and the rotation of the lead screw 18 is driven by the motor 181, thereby driving the movement of the sliding block 182, and the surface of the partition 4 113 is symmetrically fixedly provided with a switch component 114 at the position corresponding to the two sliding blocks 182, and the switch component 114 can control the start and stop of the motor 181.

[0048] refer to Figure 5-Figure 9 A partition plate 53 is symmetrically fixedly installed on the upper surface of the placement plate 5, and a distance is left between the partition plate 53 and the waterproof plate 17, and the L-shaped push plate 1 41 and the push plate 2 42 are slidably arranged between the two partition plates 53. A sliding groove 183 is provided on the outer side of the sliding block 182, and the upper end of the push plate 2 42 is slidably arranged in the sliding groove 183, so as to improve the stability of the push plate 2 42 sliding on the surface of the L-shaped push plate 1 41.

[0049] refer to Figure 5-Figure 9 A sliding shaft 43 is symmetrically fixed on the surface of the push plate 42, and the sliding shaft 43 passes through the side of the L-shaped push plate 41 and slides together. A spring 44 is fixedly connected between the L-shaped push plate 41 and the push plate 42 and is sleeved on the surface of the sliding shaft 43. The spring 44 is used to help the push plate 42 to reset. A switch part 45 is fixedly set on the surface of the L-shaped push plate 41 corresponding to the push plate 42.

[0050] refer to Figure 5-Figure 9 A row of cylindrical grooves 411 are provided on the lower surface of the L-shaped push plate 41, and a cylindrical top block 413 is slidably arranged in the groove 411. The diameter of the top block 413 is the same as the diameter of the water-permeable hole 51 and corresponds to the position of the water-permeable hole 51. A spring 412 is fixedly arranged on the upper end surface of the top block 413. The spring 412 is fixed in the groove 411. By sliding the L-shaped push plate 41 on the surface of the placing plate 5, the top block 413 can push the river garbage remaining in the water-permeable hole 51 to the surface of the drainage plate 52 under the thrust of the spring 412, and then enter the surface of the filter plate 16 along with the river water on the surface of the drainage plate 52.

[0051] Furthermore, after a period of river garbage loading, a lot of river garbage will accumulate on the surface of the placement plate 5. At this time, the motor 181 is started to drive the rotation of the lead screw 18, thereby driving the sliding block 182 to slide. The sliding of the sliding block 182 can drive the L-shaped push plate 1 41 and the push plate 2 42 to move on the surface of the placement plate 5. During the movement, the L-shaped push plate 1 41 cooperates with the push plate 2 42 to push the river garbage on the surface of the placement plate 5 in a shovel-like manner. During the movement, after the river garbage is pushed to the position of the partition plate 11, the river garbage begins to be squeezed. During the squeezing process, the river remaining in the river garbage will be removed. The water is squeezed and separated, and enters the placement plate 5 through the filter holes on the surface of the push plate 2 42 and the L-shaped push plate 1 41, and then enters the surface of the drainage plate 52 through the water-permeable hole 2 51. At this time, the push plate 2 42 will slide on the bottom surface of the L-shaped push plate 1 41, and the spring 1 44 will be compressed until the push plate 2 42 touches the switch part 2 45, and the screw 18 stops rotating. At this time, the squeezing and dehydration of the river garbage is completed, and then the motor 181 drives the screw 18 to reverse, so that the sliding block 182 is reset. After the sliding block 182 touches the switch part 114, the screw stops rotating and waits for the next push and squeeze of the garbage.
