Description

Technical Field

[0001] The present invention relates to the technical field of ecological environment restoration, and in particular to a water conservancy environment restoration construction device. Background Art

[0002] The ecological environment refers to the quantity and quality of water, land, biological, and climate resources that influence human survival and development. It is a complex ecosystem crucial to the sustainable development of society and the economy. Ecological and environmental issues refer to the various negative feedback effects that harm human survival, resulting from the destruction and pollution of the natural environment during the process of human utilization and transformation for their own survival and development. Water conservancy channels refer to the rivers and canal systems used to guide, regulate, and store water resources. They play an important role in agricultural irrigation, urban water supply, energy development, flood control, and water ecological protection.

[0003] With the development of society, the pollution of river water is becoming more and more serious. A large amount of garbage and leaves from bushes often float on the river surface.

A pair of support plates 22 are each provided with a push plate 4 on one side close to each other, and the push plate 4 is arranged in contact with the conveyor belt 21. The push plate 4 is fixedly connected to a moving rod 5 on the side close to the support plate 22, and the moving rod 5 slides through the support plate 22.

[0029] In the present invention, the driving motor 23 is provided to drive the active roller to rotate, and the conveyor belt 21 is moved with the assistance of the active roller and a plurality of driven rollers to salvage the garbage and fallen leaves on the river surface, and a push plate 4 is provided on the support plate 22 and the push plate 4 is fitted with the conveyor belt 21. The push plate 4 is pushed by the moving rod 5 to push the squeezed fallen leaves and garbage together, so that the squeezing roller 33 can better squeeze out the moisture in the garbage and fallen leaves.

[0030] Preferably, Figures 1 to 4 As shown, the driving member 34 includes a propulsion cylinder 341, which is fixedly connected to the outer side of the support plate 22. The driving end of the propulsion cylinder 341 is perpendicular to the conveying direction of the conveyor belt 21. The driving end of the propulsion cylinder 341 is fixedly connected to a movable plate 342. The movable plate 342 is fixedly connected to a plurality of connecting rods 343 on the side close to the support plate 22. A plurality of first sliding grooves 344 are opened on the support plate 22 along the driving end direction of the propulsion cylinder 341. The connecting rods 343 of the plurality of pressure plates 31 are all slidably arranged in the plurality of first sliding grooves 344 one by one. One end of the plurality of connecting rods 343 is fixedly connected to the pressure plate 31. A linking member 6 is provided on the outer side of the support plate 22. The linking member 6 pushes The driving end of the air intake cylinder 341 is connected to the push plate 4, and when the pressure plate 31 moves downward, a pair of push plates 4 move away from each other, and when the pressure plate 31 moves upward, a pair of push plates 4 move toward each other. The fixed connecting part includes a fixed plate 61, and the fixed plate 61 is fixedly connected to one side of the support plate 22. A second sliding groove 62 is provided on the fixed plate 61, and a moving block 63 is slidingly provided in the second sliding groove 62.

A telescopic rod 65 is provided in the second sliding groove 62, and one end of the telescopic rod 65 is fixedly connected to the moving block 63, and the other end is fixedly connected to the fixed plate 61.

[0031] When the present invention needs to clean up the garbage and fallen leaves on the river surface, the propulsion cylinder 341 is turned on to propel the movable plate 342. When the movable plate 342 moves downward, the pressure plate 31 is driven downward by the connecting rod 343, so that the squeezing roller 33 squeezes the garbage and fallen leaves on the conveyor belt 21 through the hinged rod, and at the same time, the movable plate 342 that moves downward will make the movable block 63 slide in the second sliding groove 62 through the second hinged rod 64, and compress the telescopic rod 65. Since one end of the movable rod 5 is fixedly connected to the movable block 63, the movable block 63 will pull the push plate 4 through the movable rod 5 to move it toward the side of the support plate 22. After the extrusion is completed, when the propulsion cylinder 341 is pulled up, the extrusion rollers 33 will move closer to each other, and the upward movement of the moving plate 342 will drive the moving block 63 to move through the second hinged rod 64. At this time, the moving block 63 will drive the moving rod 5 to move, thereby pushing the push plate 4 through the moving rod 5, and the garbage and fallen leaves that have been squeezed once will be gathered together again, so that they can be squeezed again by the extrusion roller 33. The extrusion action and the propulsion of the push plate 4 in the present invention complement each other. Not only do they share the same drive to save energy consumption, but the combination of extrusion and propulsion can squeeze the garbage and fallen leaves multiple times, further reducing the moisture in the garbage and fallen leaves, increasing the storage amount that can be salvaged in one salvage, and thus improving the efficiency of salvage.

[0032] Preferably, Figures 1 to 4As shown, a first return spring 7 is sleeved on the telescopic rod 65 , one end of the first return spring 7 is fixedly connected to the moving block 63 , and the other end is fixedly connected to the fixed plate 61 , and a plurality of drainage holes 8 are opened on the conveyor belt 21 .

[0033] In the present invention, a first return spring 7 is provided on the telescopic rod 65. When the movable plate 342 moves downward, the first return spring 7 can, on the one hand, cushion the movement of the movable block 63 so that the device can operate more accurately. On the other hand, when the movable plate 342 moves upward, the squeezed spring can provide a certain amount of assistance, thereby pushing the push plate 4 out more quickly and gathering the garbage and fallen leaves on the conveyor belt 21.

[0034] Preferably, Figures 1 to 6 As shown, the support is rotatably connected to the side close to the water surface, and a rotating sleeve 10 is fixed on the rotating rod 9. A plurality of placement grooves 11 are opened on the periphery of the rotating sleeve 10, and a plurality of stirring blades 12 are provided on the periphery of the placement grooves 11. The plurality of stirring blades 12 are arranged in a one-to-one correspondence with the plurality of placement grooves 11. A second return spring 13 is provided in the placement groove 11, and the second return spring 13 is fixedly connected to the stirring blade 12. The stirring blade 12 is provided with an arc-shaped transition edge on the side that fits the conveyor belt 21. A carrying plate 14 is fixedly connected between a pair of support columns, and an inclined scraper 15 is fixedly connected to the carrying plate 14, and the scraper 15 is fitted to the bottom of the conveyor belt 21.

[0035] In the present invention, the rotating rod 9 is rotated by external drive, and the rotating rotating rod 9 transports the garbage and fallen leaves on the water surface to the conveyor belt 21 through the stirring blade 12 provided on the connecting sleeve, and the stirring blade 12 in the present invention contacts the conveyor belt 21, so as to better transport the fallen leaves and garbage to the conveyor belt 21. When the stirring blade 12 contacts the conveyor belt 21, it will turn in a certain direction and squeeze or stretch the second return spring 13, and the contact side of the stirring blade 12 with the conveyor belt 21 is arranged in an arc shape, so as to better fit the conveyor belt 21, and the fallen leaves attached to the conveyor belt 21 are scraped off by the inclined scraper 15.

[0036] The method of using the water conservancy environment restoration construction device of the present invention is as follows:

[0037] The rotating rod 9 is rotated by an external drive, and the rotating rotating rod 9 transports the garbage and fallen leaves on the water surface to the conveyor belt 21 through the stirring blades 12 provided on the rotating sleeve 10. The driving motor 23 drives the active roller provided to rotate, and the conveyor belt 21 is moved with the assistance of the active roller and a plurality of driven rollers to salvage the garbage and fallen leaves on the river surface.

[0038] When the conveyor belt 21 is operating, the propulsion cylinder 341 is turned on to propel the movable plate 342. When the movable plate 342 moves downward, the pressure plate 31 is driven downward by the connecting rod 343. The first hinge rod 32 is used to move a pair of squeezing rollers 33 to both sides. The squeezing rollers 33 will squeeze the garbage and fallen leaves on the conveyor belt 21, squeeze out the excess water in the two and pass through, and at the same time stretch the third compound spring. At the same time, the downward moving plate 342 will make the moving block 63 slide in the second sliding groove 62 through the second hinge rod 64, and compress the telescopic rod 65. Because one end of the moving rod 5 is fixedly connected to the moving block 63, the moving block 63 will pull the push plate 4 through the moving rod 5 to move it to the side of the support plate 22.

[0039] When one extrusion is completed, the squeezing rollers 33 will move closer to each other when the propulsion cylinder 341 is pulled up, and the upward movement of the movable plate 342 will drive the movable block 63 to move through the second hinged rod 64. At this time, the movable block 63 will drive the movable rod 5 to move, thereby pushing the push plate 4 through the movable rod 5, and the garbage and fallen leaves after the squeeze will be gathered together again so that the squeezing rollers 33 can better squeeze out the moisture in the garbage and fallen leaves.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
