Description
Technical Field
[0001] The invention relates to the technical field of hydrodynamic pollution cleaning, in particular to a hydrodynamic pollution cleaning device. Background Art
[0002] A trash cleaning machine is a device arranged at the water inlet of a project to intercept and clean floating objects such as branches, leaves, weeds, garbage, and ice floes brought by the water flow. At the same time, a trash cleaning machine is a mechanical equipment that removes debris (generally called trash) attached to the trash rack. In reservoirs or rivers with a lot of dirt, in order to ensure the safe and normal operation of hydropower stations or pumping stations, it is often necessary to install a trash cleaning machine so that the dirt can be cleaned without stopping the machine or draining the reservoir.
[0003] The rotary trash cleaning machine mainly consists of three parts: a trash rack, a tooth rake, and a transmission system. In the previous design of a rotary trash cleaning machine, the driving mechanism is usually arranged on the upper part of the rack body and driven by a motor. The active sprocket on the output shaft of the reducer drives the driven sprocket on the wheel axle group through a chain drive. The driven sprocket transmits the torque to the main shaft of the wheel axle group. The traction sprocket on the main shaft drives the plate roller chain to rotate, so that the cleaning tooth rake rotates along the rack body with the plate roller chain to remove the floating objects in front of the rack body from the water. At the same time, during the use of the trash rack, especially in the flood season, a large amount of debris accumulates on the trash rack, which can easily damage the trash rack on the one hand, and cause serious head loss for a long time on the other hand, resulting in a waste of water resources, greatly reducing power generation and affecting the safety of the power station.
[0004] Moreover, during use, in some special cases, such as when the original project does not have a garbage cleaning machine or it is inconvenient to provide power for the new project, the use of traditional rotary garbage cleaning machines requires the addition of more electrical equipment, and the cleaning process requires continuous energy consumption. At the same time, when the device is used to salvage and clean the dirt in the water, due to the large amount of aquatic plants in the water, the aquatic plants are easily left inside the plate roller chain, affecting the meshing of the plate roller chain with the driven sprocket and the traction sprocket, reducing reliability. Summary of the invention
[0005] In view of the deficiencies in the prior art, the present invention provides a water powered pollution cleaning device which has a simple structure, is easy to process, and is energy-saving and reliable.
[0006] The present invention provides the following technical solution: a hydrodynamic pollution cleaning device, comprising a support frame, a grid body connected to the front side of the support frame, a traction sprocket connected to the grid body through a main shaft, and a driven sprocket connected to the driven sprocket through a driven sprocket shaft, and a plate roller chain meshingly connected between the traction sprocket and the driven sprocket; A T-shaped steering reduction box is arranged in the grid body, the input end of the T-shaped steering reduction box is connected to a driving wheel, the annular surface of the driving wheel is connected to a driving fan blade, the two ends of the front side of the grid body are respectively connected to fixing rods, the end of the fixing rod away from the grid body is connected to a pressure baffle, and a pair of pressure baffles form a triangle with a larger front and a smaller back.
[0007] Preferably, a mounting plate is connected inside the grid body, a metal fixing plate is connected to the rear side of the mounting plate, and a first swing plate is hingedly connected to the rear surface of the metal fixing plate.
[0008] Preferably, the side surface of the first swing plate is connected to a cleaning brush mounting transverse plate, and the side surface of the cleaning brush mounting transverse plate is provided with an impurity cleaning bristle brush.
[0009] Preferably, the upper surface of the cleaning brush mounting transverse plate is hingedly connected to a second swing plate, the upper surface of the second swing plate is hingedly connected to a third swing plate, and the third swing plate is movably connected to the mounting plate.
[0010] Preferably, a spring is connected to the lower surface of the first swing plate, and the spring is connected to the mounting plate.
[0011] Preferably, a tooth rake is provided on the surface of the leaf roller chain.
[0012] Preferably, the grid body is arranged obliquely, and the interior of the grid body is arranged hollowed out.
[0013] Preferably, the grid body is arranged at an angle of 75° to the horizontal plane after installation.
[0014] Preferably, a buffer device is provided at the end of the I-beam of the support frame.
[0015] Preferably, the upper surface of the support frame is connected with a hinge.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adopts hydraulic drive to drive the driving blades and the driving wheel to rotate, and then drives the traction sprocket through the T-type steering reduction box, so as to realize the rotation of the plate roller chain. Since the distance between the two pressure baffles decreases successively, the water can be discharged in a concentrated manner when passing through the inside of the pressure baffle, thereby increasing the water pressure of the driving blades, thereby improving the hydraulic drive efficiency of the device, so that it can meet the pollution cleaning needs while achieving energy conservation and emission reduction.
[0017] 2. In the present invention, since the impurity cleaning bristle brush is in contact with the inner side of the plate roller chain, when the plate roller chain drives the tooth rake to move, the movement of the first swing plate, the second swing plate and the third swing plate enables the impurity cleaning bristle brush to move to squeeze or pull the elastic spring. In this way, the impurity cleaning bristle brush can bounce repeatedly to clean the impurities on the surface of the plate roller chain, thereby preventing impurities from being entangled on the surface of the plate roller chain, thereby ensuring the reliability of the engagement between the plate roller chain and the driven sprocket and the traction sprocket.

[0019] 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.
[0020] See also Figure 1-5 The hydrodynamic cleaning device does not need to be equipped with track embedded parts. A supporting structure (i.e., support frame 1) is arranged at the bottom of the grid body 5, and the grid body 5 is supported by an I-beam welded frame structure, so that the grid body 5 forms an angle of 75° with the horizontal plane after installation to ensure the smooth operation of the cleaning device and prevent it from overturning; a buffer device, such as bakelite, can be arranged at the end of the I-beam of the supporting structure to prevent damage to the original civil engineering structure during installation; The rear surface of the support frame 1 is connected with a grid body 5, in which a traction sprocket 9 is connected via a main shaft, and a driven sprocket 6 is connected via a driven sprocket shaft, and a plate roller chain 7 is meshedly connected between the traction sprocket 9 and the driven sprocket 6; The surface of the leaf roller chain 7 is provided with toothed rakes 8, and the interior of the fence body 5 is hollowed out. It also includes a driving wheel 2 and a T-type steering reduction box 4. A support hinge is arranged on the upper part of the supporting structure for installing the driving wheel 2. Two traction sprockets 9 are symmetrically installed on a pair of main shafts. The pair of main shafts are connected to the output ends of both ends of the T-type steering reduction box 4 respectively. Two driven sprockets 6 are symmetrically installed on the driven sprocket shafts. A plate roller chain 7 connects the traction sprocket 9 and the driven sprocket 6. When the hydrodynamic sewage cleaning device is working, the driving wheel 2 transmits the torque to the main shaft through the reduction box, and the main shaft drives the two traction sprockets 9 to rotate. The two traction sprockets 9 respectively drive the corresponding driven sprockets 6, the plate roller chain 7 and the roller chains installed on the rollers. The tooth rake 8 on the sub-chain rotates around the fence body 5. After the driving wheel 2 is installed, there is a partial cantilever structure. In order to reduce the axial stress of the driving wheel 2, an empty box structure can be designed inside the wheel to use buoyancy to reduce the stress caused by its own weight. The tooth rake 8 of the hydrodynamic cleaning device is divided into two groups and symmetrically arranged on both sides of the driving wheel 2. Each group of sprockets controls a group of tooth rakes 8. The tooth rake 8 is installed on the shaft of the plate roller chain 7 and rotates around the fence body 5 with the plate roller chain 7 to pick up the dirt in the water. When the tooth rake 8 runs to the top of the fence body 5, it flips with the traction chain. At this time, the dirt on the tooth rake 8 falls off by itself and can be transmitted and collected through the conveyor belt.
[0021] A T-type steering reduction box 4 is arranged in the grid body 5, the input end of the T-type steering reduction box 4 is connected to the driving wheel 2, the annular surface of the driving wheel 2 is connected to the driving blades 3, the two ends of the front side of the grid body 5 are respectively connected to the fixing rods 18, the end of the fixing rod 18 away from the grid body 5 is connected to the pressure baffle 19, and a pair of pressure baffles 19 form a triangle with a large front and a small back (i.e., a triangular cross section). It is driven by hydraulic power, thereby driving the driving blades and the driving wheel to rotate, and then driving the traction sprocket through the T-type steering reduction box, so as to realize the rotation of the plate roller chain. Since the distance between the two pressure baffles 19 decreases successively, when the water passes through the inside of the pressure baffle 19, the water can be discharged in a concentrated manner to increase the water pressure of the driving blades 3, thereby improving the hydraulic driving efficiency of the device, so that it can meet the pollution cleaning needs while achieving energy saving and emission reduction.
[0022] A mounting plate 11 is connected inside the grid body 5, a metal fixing plate 14 is connected to the rear side of the mounting plate 11, a first swing plate 13 is hingedly connected to the rear surface of the metal fixing plate 14, a cleaning brush mounting transverse plate 16 is connected to the side surface of the first swing plate 13, a bristle brush 10 for cleaning impurities is arranged on the side surface of the cleaning brush mounting transverse plate 16, a second swing plate 17 is hingedly connected to the upper surface of the cleaning brush mounting transverse plate 16, a third swing plate 12 is hingedly connected to the upper surface of the second swing plate 17, and the third swing plate 12 is movably connected to the mounting plate 11, and an elastic spring 15 is connected to the lower surface of the first swing plate 13. And the elastic spring 15 is connected to the mounting plate 11. Since the impurity cleaning bristle brush 10 is in contact with the inner side of the plate roller chain 7, when the plate roller chain 7 drives the tooth rake 8 to move, the movement of the first swing plate 13, the second swing plate 17 and the third swing plate 12 can be utilized to make the impurity cleaning bristle brush 10 move to squeeze or pull the elastic spring 15. In this way, the impurity cleaning bristle brush 10 can bounce repeatedly to clean the impurities on the surface of the plate roller chain 7, thereby preventing impurities from being entangled on the surface of the plate roller chain 7, thereby ensuring the reliability of the engagement between the plate roller chain 7 and the driven sprocket 6 and the traction sprocket 9.
