Description

Technical Field

[0001] The present invention relates to the technical field of river garbage cleaning, and specifically provides a river garbage cleaning device for water conservancy projects. Background Art

[0002] With the acceleration of the urbanization process and the improvement of people's living standards, the problem of river garbage has become increasingly serious, becoming one of the important factors restricting the sustainable development of the ecological environment. The floating objects on the river surface mainly include waste such as plastic bottles, plastic bags, waste paper, and branches. These garbage not only affect the beauty of the river, damage the aquatic ecosystem, and even threaten human health, but also may hinder the flood discharge capacity of the river, bringing many adverse effects to the normal operation of water conservancy projects.

[0003] The existing Chinese patent with the publication number CN112900393B includes a support frame and support rods. The number of both the support frame and the support rods is two. The front and rear ends of the two support rods are respectively fixedly connected to the mutually close surfaces of the two support frames. A collection structure is arranged below the two support rods between the two support frames. The collection structure is fixedly sleeved on the outer surfaces of the two support rods, and the collection structure is sleeved on the outer surface of the conveying pipe.

[0004] When the above device is in use, by setting a transmission shaft, a cutting knife, and a torsion spring, when the movable leakage plate and the driving leakage plate rotate under the action of the conveying pipe, when the movable leakage plate and the driving leakage plate rotate to the lower part, the cutting knife is pushed to rotate. The torsion spring is twisted by driving the transmission shaft, so that the cutting knife cuts the garbage at the bottom of the outer leakage cylinder, reducing the volume of the garbage, and achieving the effect of shredding the garbage that cannot enter the inside of the conveying pipe due to its too large volume. However, in the actual use process, in rainy or dry weather, and there are differences in the water level of the river, resulting in the cleaning device being unable to effectively intercept and collect the garbage in the river water body, thus affecting the cleaning effect of river garbage. Therefore, it is difficult to flexibly adjust the cleaning device according to the water level change in the river.

[0005] Therefore, we propose a river garbage cleaning device for water conservancy projects. Summary of the Invention

[0006] The purpose of the present invention is to provide a river garbage cleaning device for water conservancy projects, which has the advantage of being able to flexibly adjust the cleaning device according to the water level change in the river, and solves the problems in the background art.

[0007] To achieve the above object, the present invention provides the following technical solution: A river channel garbage cleaning device for water conservancy projects, including support frames fixed on both sides of the river bank. The bottoms of both support frames are penetrated and connected with lifting rods in a lifting and moving manner.

[0008] Preferably, a fixed block is fixedly connected to one of the lifting rods. The end of the fixed block is penetrated and rotatably connected with a spline shaft rod. A first bevel gear for driving the salvage roller to rotate is coaxially fixed to the bottom end of the spline shaft rod. Second bevel gears are coaxially fixed to symmetric positions at both ends of the salvage roller, and the first bevel gear is meshed and driven with the second bevel gear on the adjacent side.

[0009] Preferably, a spline sleeve rod driven to rotate by a power mechanism is penetrated and rotatably connected to the corresponding position of the support frame near the spline shaft rod. The spline sleeve rod is sleeved on the outer contour of the spline shaft rod and is connected in a lifting and moving manner.

[0010] Preferably, the salvage mechanism includes a plurality of uniformly arranged support grooves provided at corresponding positions of both ends of the salvage roller and the filter plate. The support grooves are communicated with the moving grooves. A support block for supporting the filter plate is movably connected to the inner wall of each support groove. Cam grooves for movably supporting the support blocks are provided on the opposite surfaces of the two discs. One end of each support block away from the filter plate penetrates to the inner wall of the adjacent cam groove and is movably connected.

[0011] Preferably, a cleaning mechanism for cleaning the garbage on the surface of the filter plate is provided on the salvage roller. The cleaning mechanism includes rings fixedly connected to the outer contours of symmetric positions at both ends of the salvage roller. A plurality of uniformly arranged cleaning rollers are penetrated and rotatably connected to the opposite surfaces of the two rings. Each cleaning roller is in contact with the surface of the filter plate on the adjacent side. Tooth rings for driving the cleaning rollers to rotate in a fixed-axis manner are fixedly connected to the two discs through external support brackets. Gears meshed and driven with the tooth rings are coaxially fixed to symmetric positions at both ends of each cleaning roller.

[0012] Preferably, one side of the two lifting rods near the bottom end is fixedly connected to a collection box for collecting river garbage through an external bracket, and one side of the collection box near the salvage roller is fixedly connected to a guide plate for guiding the river garbage into the collection box, and the end of the guide plate away from the collection box is in contact with the outer contour of the circular ring and movably connected.

[0013] Preferably, the lifting rod is provided with a guiding mechanism for guiding the garbage on both sides of the river channel, and the guiding mechanism includes two guiding rods fixedly connected at symmetrical positions on one side of the lifting rod away from the collecting box to guide the garbage on both sides of the river channel to the salvage roller position, and the ends of the two guiding rods away from the salvage roller are penetrated and connected with a moving blade for moving the garbage on both sides of the river channel to the center position for rotating on a fixed axis.

[0014] Preferably, two symmetrically placed connecting blocks are fixedly connected on the back surfaces of the guide rods on both sides, and a worm for driving the moving blades to rotate is penetrated and rotatably connected to the two connecting blocks on each side, and the ends of the two moving blades are coaxially fixedly connected to a worm wheel for meshing transmission with the worm, and the ends of the worms on both sides away from the worm wheel are coaxially fixedly connected to a third conical tooth for meshing transmission with the second conical tooth on the adjacent side.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a floating block at the bottom of the lifting rod and cooperating with the spring in the movable groove, when the water level of the river changes, the floating block can push the lifting rod to move up and down along the inner wall of the movable groove under the action of buoyancy, thereby driving the salvage roller and the salvage mechanism to adjust the height synchronously. When the river water rises or falls, the salvage roller can rise or fall accordingly, and always block the floating objects on the water surface on the side where the filter plate extends, ensuring effective interception of garbage; effectively solves the problem that the cleaning equipment of the existing device cannot effectively intercept and collect garbage in the river water due to the difference in river water level in rainy or dry weather, significantly improves the effect of river garbage cleaning, adapts to the operation needs under different water level conditions, and ensures the cleanliness of the river and the normal operation of water conservancy projects.

[0017] II. Through the support grooves opened at both ends of the salvage roller, there are support blocks movably connected inside the support grooves. Cam grooves are opened on the opposite surfaces of the discs. One end of the support block penetrates through to the inner wall of the cam groove and is movably connected. During the rotation of the salvage roller, the support block pulls the filter plate to perform reciprocating telescopic movement on the inner wall of the moving groove under the action of the cam groove. When the filter plate extends underwater, it can salvage the garbage in the river water and the floating objects blocked on one side of the salvage roller. And when the salvage roller rotates and disengages from the water surface, the filter plate can filter the excess water in the surface river garbage, enabling the river garbage to adhere to the surface of the filter plate, facilitating subsequent cleaning, enhancing the cleaning ability of the equipment for river garbage, being able to more effectively collect and process the floating objects in the river, improving the efficiency and quality of garbage cleaning, reducing the residence time of garbage in the river, and being beneficial to protecting the river ecological environment.

[0018] III. When the salvage roller drives the ring to rotate, the gear drives the cleaning roller to perform fixed-axis rotation on the ring under the action of the toothed ring. The cleaning roller is in contact with the surface of the filter plate. As the filter plate contracts and moves, the cleaning roller can rotate and clean the river garbage attached to the surface of the filter plate. At the same time, a collection box is fixedly connected to the side close to the bottom end of the lifting rod, and a guide plate is fixedly connected to the side of the collection box close to the salvage roller. The river garbage cleaned by the cleaning roller falls on the guide plate under the action of gravity, and the guide plate guides the river garbage into the collection box for centralized collection, without frequent manual intervention, reducing the manual labor intensity and cost, improving the efficiency and safety of garbage disposal, and at the same time avoiding secondary pollution of the garbage, making the river garbage cleaning work more efficient, convenient and environmentally friendly.

[0019] IV. Through the meshing transmission of components such as the worm, worm gear and third conical gear, when the salvage roller drives the second conical gear to rotate, the third conical gear can drive the worm to perform fixed-axis rotation on the connecting block. The worm gear drives the two side stirring blades to rotate relatively under the action of the worm. The rotation of the stirring blades stirs the floating objects on both sides of the river towards the central position, and then the guiding rod can guide the floating objects on both sides of the river towards the position of the salvage roller, effectively expanding the operation range of the river garbage cleaning equipment, enabling the garbage on both sides of the river to be smoothly guided to the position of the salvage roller for cleaning, further improving the comprehensiveness and thoroughness of river garbage cleaning, ensuring the overall cleanliness and beauty of the river, and being of great significance for maintaining the river ecological environment and the functions of water conservancy projects.

[0020] By the combined use of the above structures, it solves the problem that in the actual use process of the existing device, in rainy or dry weather, and there are differences in the water level of the river, resulting in the cleaning equipment being unable to effectively intercept and collect the garbage in the river water body, thus affecting the cleaning effect of river garbage, and therefore it is difficult to flexibly adjust the cleaning equipment according to the water level change in the river.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0031] See also Figures 1 to 8, the present invention provides a technical solution: a river garbage cleaning device for water conservancy projects, including a support frame 1 fixed on both sides of the river bank. The bottoms of both support frames 1 are penetrated and connected with a lifting rod 2 in a lifting and moving manner. An activity groove 101 for supporting the moving direction of the lifting rod 2 is opened on each of the two support frames 1. The opposite surfaces of the bottoms of the two lifting rods 2 are penetrated and fixedly connected with a disc 3. The opposite surfaces of the two discs 3 are penetrated and rotatably connected with a salvage roller 4 through a fixed axis. A plurality of uniformly arranged moving grooves 401 are opened on the outer contour of the salvage roller 4. The inner wall of each moving groove 401 is telescopically and movably connected with a filter plate 5 for salvaging river garbage. The bottoms of the two lifting rods 2 are fixedly connected with a floating block 7 for adaptively adjusting the height of the salvage roller 4. A spring 6 for guiding the lifting rod 2 to move back is fixedly connected to the inner wall of the activity groove 101. A salvage mechanism for driving the filter plate 5 to clean the river garbage is provided on the salvage roller 4.

[0032] When in use, by setting the support frame 1 and fixing and supporting the support frame 1 on both sides of the river bank, the stability of the cleaning device is improved. Through the lifting rod 2 arranged on the activity groove 101 and the activity groove 101 opened on the support frame 1, the activity groove 101 can support the moving direction of the lifting rod 2. Through the disc 3 arranged on the lifting rod 2, the disc 3 is fixedly supported on the lifting rod 2. Through the salvage roller 4 arranged on the disc 3, the salvage roller 4 can be rotatably supported on the disc 3. Through the moving groove 401 opened on the salvage roller 4 and the filter plate 5 arranged on the moving groove 401, the moving groove 401 can support the moving direction of the filter plate 5, and the salvage mechanism arranged on the salvage roller 4 can drive the filter plate 5 to rotate to salvage and clean the river garbage.

[0033] Through the floating block 7 arranged on the lifting rod 2, and the floating block 7 can float on the water surface, the floating block 7 can support the lifting rod 2. At the same time, the bottom side of the salvage roller 4 is located under the water surface. When the river water rises, the floating block 7 can push the lifting rod 2 to move and adjust along the inner wall of the activity groove 101 in the upward vertical direction under the action of buoyancy. At the same time, the lifting rod 2 can drive the salvage mechanism to move synchronously for height adjustment. And the spring 6 arranged on the activity groove 101 is compressed and contracted under the action of the lifting rod 2 at this time. When the river water drops and the spring 6 is in a compressed and contracted state, the lifting rod 2 can drive the salvage mechanism to move and adjust in the downward vertical direction under the elastic force of the spring 6, realizing automatic adjustment of the height of the salvage mechanism according to the water level height and improving the effect of river garbage cleaning. Embodiment Two:

[0034] On the basis of Embodiment One, further:

[0035] One of the lifting rods 2 is fixedly connected with a fixed block 8. The end of the fixed block 8 is penetrated and rotatably connected with a spline shaft rod 9 in a fixed axis.

Through the spline shaft rod 9 provided on the fixed block 8, and the first conical gear 10 provided on the spline shaft rod 9, the first conical gear 10 is coaxially fixedly connected with the spline shaft rod 9, enabling the spline shaft rod 9 to drive the first conical gear 10 to rotate in a fixed axis connection on the fixed block 8. Through the second conical gear 11 provided on the fishing roller 4, the teeth of the second conical gear 11 and the first conical gear 10 are meshed with each other.

[0038] Through the spline sleeve rod 12 provided on the support frame 1, and the spline sleeve rod 12 is sleeved on the outer contour of the spline shaft rod 9 and is connected for lifting movement. Along with the lifting rod 2 reciprocatingly adjusting up and down on the inner wall of the movable groove 101, thus the spline shaft rod 9 can synchronously move back and forth telescopically on the inner wall of the spline sleeve rod 12 under the action of the lifting rod 2, avoiding hindering the height adjustment of the lifting rod 2. And the spline sleeve rod 12 is driven to rotate by a motor, then the motor can drive the spline sleeve rod 12 to rotate in a fixed axis on the support frame 1, enabling the spline shaft rod 9 to drive the first conical gear 10 to rotate in a fixed axis synchronously on the fixed block 8 under the action of the spline sleeve rod 12. Along with the meshing transmission between the first conical gear 10 and the second conical gear 11, further, the second conical gear 11 can drive the fishing roller 4 to rotate in a fixed axis on the disc 3 under the action of the first conical gear 10, so as to facilitate the subsequent fishing roller 4 to drive the filter plate 5 to clean the river channel garbage.

With the rotation of the salvage roller 4 in the direction of D, the salvage roller 4 can drive the bottom filter plate 5 to salvage garbage in the river water and floating objects blocked on one side of the salvage roller 4. When the salvage roller 4 drives the salvage roller 4 to rotate and break contact with the water surface, the filter plate 5 can filter excess water in the surface river garbage, and the river garbage can be attached to the surface of the filter plate 5. When the salvage roller 4 drives the filter plate 5 to rotate to the top side and rotate in the direction of D, the support block 13 can pull the filter plate 5 toward the inner wall of the movable groove 401 to retract and move under the action of the cam groove 301, so as to facilitate the subsequent cleaning of the garbage attached to the surface of the filter plate 5.
