Description

Technical Field

[0001] The invention relates to the field of environmental protection, and in particular to an automatic river water purification device. Background Art

[0002] At present, in order to purify the water quality of rivers, the commonly used method is to set up river dams in the river to block the garbage floating on the water surface and prevent the garbage from flowing downstream with the water flow. Then, manpower is regularly organized to salvage and remove the garbage intercepted by the river dams. The problem with this method is that it is time-consuming and labor-intensive, and the labor cost is high.

[0003] In recent years, with the development of social economy, labor costs are getting higher and higher. How to reduce the labor cost of garbage salvage has become an urgent problem to be solved. Therefore, various automatic garbage salvage equipment has appeared on the market to replace manual salvage, reduce labor costs, and realize automatic purification of river water quality, such as the patent with publication number CN118771508B. Although this type of automatic river water purification device realizes automatic garbage salvage, it generally has the problem of high energy consumption. It works continuously 24 hours a day, all year round, and consumes huge amounts of electricity over the years, which does not conform to the development concept of green environmental protection.

[0020] The present invention proposes an automatic river water purification device. The power required for the operation of the automatic river water purification device is all obtained from the water flow, and no external power supply is required. The cost of purchasing electricity during the operation of the device is 0, which significantly reduces energy consumption and operating costs and is in line with the development concept of green environmental protection.

[0021] Specifically, in one embodiment of the invention, Figure 1 and Figure 2As shown, the automatic river water purification device comprises: a dam 1 and a plurality of purification modules, wherein the dam 1 spans the river and is fixedly connected to the riverbanks 22 on both sides of the river. A channel 2 is arranged inside the dam 1, and a crossing 23 is arranged inside the riverbank 22. The channel 2 extends to both ends of the dam 1 and communicates with the crossings 23 in the riverbanks 22 on both sides. With such a design, vehicles and personnel can enter the channel 2 through the crossings 23 and move from one side of the river to the other side. The upper surface of the dam 1 is located below the water surface of the river. With such a design, the water flow in the river flows downstream over the dam 1, so the water level 11 of the river is higher than the dam 1 and lower than the riverbank 22.

[0022] Preferably, the barrage 1 and the river bank 22 are both made of concrete.

[0023] In this embodiment, multiple purification modules are provided on the upper surface of the dam 1 and arranged in a straight line on the upper surface of the dam 1. Two adjacent purification modules are fixedly connected. The purification modules located at both ends of the dam 1 are fixedly connected to the river bank 22, and the river water quality is automatically purified through the purification modules.

[0024] Specifically, Figure 1-Figure 5 As shown, a purification module includes: protrusion 13, protrusion 24, protrusion 35, baffle plate 19, guide plate 120, guide plate 21, the protrusion 13 is fixedly installed on the upper surface of the dam 1, and the upper surface of the protrusion 13 is higher than the water surface of the river. This design can prevent the rotating shaft 19 and the rotating shaft 4 14, the driving wheel 12 and the driven wheel 13, and the crank 15 connecting rod 17 mechanism from being immersed in water and being corroded or damaged. The upper surface of the protrusion 13 is rotatably mounted with the rotating shaft 19 and the rotating shaft 4 14 through the shaft seat 8. The rotating shaft 19 and the rotating shaft 4 14 are connected to each other through the driving wheel 12 and the driven wheel 13. The rotating shaft 19 is connected to the water wheel 10, and the lower end of the water wheel 10 is immersed in the water flow of the river. The water flow of the river drives the water wheel 10 to drive the rotating shaft 19 to rotate. The rotating shaft 4 14 is connected to the buoyancy tank 18 through the crank 15 connecting rod 17 mechanism. Specifically, as shown Figure 1-Figure 5 As shown, the crank 15-connecting rod 17 mechanism includes a crank 15, a pin 16, and a connecting rod 17. The crank 15 is fixedly connected to the rotating shaft 4 14. One end of the connecting rod 17 is hinged to the crank 15 through the pin 16, and the other end of the connecting rod 17 is hinged to the buoy 18. The buoy 18 floats on the water surface of the river. The rotation of the rotating shaft 19 drives the rotating shaft 4 14 to rotate. The rotation of the rotating shaft 4 14 drives the buoy 18 to reciprocate on the water surface of the river through the crank 15-connecting rod 17 mechanism, and the moving direction is perpendicular to the water flow direction of the river. Only by such a design can the garbage be continuously pushed into the slag drop hole 6 with the help of the reciprocating movement of the buoy 18 on the water surface of the river.

[0025] Specifically, Figure 1-Figure 5As shown, the protrusion 24 is fixedly installed on the upper surface of the dam 1 and is spaced apart from the protrusion 13. The pontoon 18 is located between the protrusion 13 and the protrusion 24 on the upper surface of the dam 1. The pontoon 18 reciprocates on the water surface of the river channel between the protrusion 13 and the protrusion 24 on the upper surface of the dam 1. The upper surface of the protrusion 24 is a slope 7, and the lower end of the slope 7 is close to the pontoon 18. The slope 7 is partially located above the water surface of the river channel. With this design, the pontoon 18 reciprocates on the water surface of the river channel to smoothly push the garbage floating on the water surface between the pontoon 18 and the protrusion 24 on the upper surface of the dam 1 onto the slope 7. As the floating garbage continuously enters between the pontoon 18 and the protrusion 24 on the upper surface of the dam 1, the reciprocating movement of the pontoon 18 pushes the garbage to move continuously to the slope 7, and then the garbage gradually rises along the slope 7 to the high end of the slope 7, and finally falls into the slag drop hole 6.

[0026] Specifically, Figure 1-Figure 5 As shown, the protrusion 3 5 is fixedly mounted on the upper surface of the dam 1 and is closely arranged with the protrusion 2 4. The upper surface of the protrusion 3 5 is higher than the water surface of the river channel, and the upper surface of the protrusion 3 5 is not higher than the high end of the slope 7. With this design, the water flow of the river channel will not flow into the slag hole 6, and the garbage rising to the high end of the slope 7 can smoothly fall into the slag hole 6. The high end of the slope 7 is close to the protrusion 3 5. The upper surface of the protrusion 3 5 is provided with a slag hole 6. The slag hole 6 is connected with the channel 2. The garbage falling into the slag hole 6 finally falls into the channel 2. One channel 2 of the dam 1 is connected with the slag holes 6 of multiple purification modules. The specific number of purification modules set on the dam 1 depends on the width of the river channel. The garbage accumulation in the channel 2 is manually observed regularly. When there is a lot of garbage, equipment such as a shovel or garbage truck can be driven into the channel 2 to clean up the garbage.

[0027] Specifically, Figure 1-Figure 5 As shown, the baffle plate 19 is vertically fixed to the upper surface downstream of the protrusion 24 and the dam 1, and the baffle plate 19 is perpendicular to the direction of the water flow in the river; the guide mesh plate 1 20 is vertically fixed to the upper surface upstream of the dam 1; the guide mesh plate 21 is vertically fixed to the upper surface upstream of the protrusion 24, and the guide mesh plate 1 20 and the guide mesh plate 2 21 are inclined relative to the direction of the water flow in the river, and the inclination directions of the guide mesh plate 1 20 and the guide mesh plate 2 21 are opposite, as shown in FIG. Figure 2 As shown in the figure, the direction indicated by the arrow is the direction of the river water flow, and the inclination directions of the guide mesh plate 1 20 and the guide mesh plate 2 21 are opposite, forming an inverted eight-shaped shape, so that the guide mesh plate 1 20 and the guide mesh plate 2 21 define a convergence area 56 of approximately isosceles trapezoidal shape upstream of the dam 1, as shown in FIG. Figure 2As shown, after the floating garbage on the river surface enters the convergence area 56 along the direction indicated by the arrow with the water flow, the floating garbage gradually gathers together under the diversion effect of the guide mesh plate 1 20 and the guide mesh plate 21, and the water can smoothly pass through the guide mesh plate 1 20 and the guide mesh plate 21 and continue to flow downstream without changing direction. The floating garbage is intercepted by the guide mesh plate 1 20 and the guide mesh plate 21 and diverted to gradually gather together in the convergence area 56, and then flows to the area between the upper surface slope 7 of the dam 1 and the pontoon 18, and is blocked by the baffle plate 19. The water flow can pass through the baffle plate 19 and continue to flow downstream without changing direction, and the floating garbage is blocked by the baffle plate 19. At this time, the pontoon 18 reciprocates left and right and is tightly connected to the baffle plate 19 and the guide mesh plate 1 20. The reciprocating movement of the pontoon 18 pushes the position The garbage in the area between the upper surface slope 7 and the pontoon 18 of the dam 1 moves to the slope 7, and then the garbage on the slope 7 gradually moves to the high end of the slope 7 under the push of subsequent garbage, and finally falls into the channel 2 through the slag hole 6, so that the cleaning of the floating garbage in the river can be completed, that is, the automatic purification of the river water quality. During the whole river water purification process, the floating garbage is limited by the guide mesh 20, the guide mesh 21, the baffle plate 19, the slope 7 and the pontoon 18 and cannot move around. It can only be pushed to the slope 7 by the pontoon 18, and then falls into the channel 2 through the slag hole 6. The power for the reciprocating movement of the pontoon 18 comes from the river water flow driving the water wheel 10 to rotate, and no external power supply is required. The cost of purchasing electricity during the operation of the device is 0, which significantly reduces energy consumption and operating costs, and is in line with the development concept of green environmental protection.

[0028] In this embodiment, if Figure 2 As shown, one end of the guide mesh plate 21 of a purification module away from the dam 1 is sealed and connected to the end of the guide mesh plate 1 20 of another adjacent purification module away from the dam 1. This design not only ensures that the river water flow is filtered and diverted without dead ends, and all garbage floating on the river water surface can enter each convergence area 56 to be filtered and removed without omission, but also defines an equipment installation area 57 between two adjacent convergence areas 56 upstream of the dam 1 for the subsequent installation of water wheel 2 31. Since no garbage enters the equipment installation area 57, the safe and stable operation of water wheel 2 31 and water wheel 10 is guaranteed.

[0029] In this embodiment, if Figure 1-Figure 5 As shown, the lower ends of the baffle plate 19, the guide plate 1 20, and the guide plate 2 21 are located below the water surface of the river, and the upper ends of the baffle plate 19, the guide plate 1 20, and the guide plate 2 21 are located above the water surface of the river. Only in this way can the floating garbage on the river surface be effectively filtered and blocked.

[0030] In this embodiment, the design of the buoyancy box 18 reciprocating left and right and slidingly connected with the baffle plate 19 and the guide mesh plate 20 can ensure that garbage will not flow away from the gap between the buoyancy box 18 and the baffle plate 19 and the guide mesh plate 20.

[0031] In this embodiment, if Figure 2 As shown, during the reciprocating movement of the buoy 18, the buoy 18 always keeps in contact with the guide mesh plate 20 and the baffle plate 19. This design can prevent garbage from entering the equipment installation area 57 and the area between the buoy 18 and the protrusion 3, causing garbage leakage without being filtered. Figure 1 and Figure 2 It can be seen that the garbage in the area between the upper surface slope 7 of the dam 1 and the pontoon 18 is blocked by the baffle plate 19 downstream, blocked by the pontoon 18 and the guide mesh plate 20 on its right side, and blocked by the slope 7 and the guide mesh plate 21 on its left side. Therefore, as long as the pontoon 18 always keeps in contact with the guide mesh plate 20 and the baffle plate 19 during the reciprocating movement of the pontoon 18, the garbage can be limited to the area between the upper surface slope 7 of the dam 1 and the pontoon 18 and will not spread around, thereby ensuring that the floating garbage on the river surface is effectively filtered and blocked, and the automatic purification of the river water quality is successfully completed.

[0032] Preferably, the protrusion 1 3, the protrusion 2 4, the protrusion 3 5, the dam 1 and the river bank 22 are cast and formed in one piece.

[0033] Further, such as Figure 2 As shown, a slag-carrying mesh plate 24 is arranged above the convergence area 56, and the two ends of the slag-carrying mesh plate 24 are sealed and connected to the sides of the guide mesh plate 1 20 and the guide mesh plate 21. A rear baffle plate 55 is arranged downstream of the upper surface of the slag-carrying mesh plate 24, and the two ends of the rear baffle plate 55 are sealed and connected to the sides of the guide mesh plate 1 20 and the guide mesh plate 21; a rotating shaft 26 is arranged upstream of the slag-carrying mesh plate 24, and the central axis of the rotating shaft 26 is perpendicular to the direction of the water flow in the river channel, and the two ends of the rotating shaft 26 are connected to the guide mesh plate 1 20 and the guide mesh plate 21. The equipment installation area 57 is provided with a water wheel 2 31, and the water wheel 2 31 is installed on the rotating shaft 30, and the rotating shaft 30 is rotatably connected with the guide mesh plate 1 20 and the guide mesh plate 2 21, and the rotating shaft 30 and the rotating shaft 2 26 are connected by the transmission wheel group 29. The water flow in the river drives the water wheel 2 31 to rotate, and the water wheel 2 31 drives the rotating shaft 3 30 and the rotating shaft 2 26 to rotate. The rotation direction of the water wheel 2 31 is opposite to the rotation direction of the rotating shaft 2 26. With this design, the hook wheel 27 can smoothly hook up the cross bar 28 floating on the water surface; Figure 2As shown, a plurality of hook wheels 27 are arranged at intervals on the rotating shaft 26. The rotating shaft 26 rotates to drive the hook wheels 27 to rotate to hook up the cross bar 28 floating on the water surface and place it on the slag carrying mesh plate 24. The rear baffle 55 is used to prevent the cross bar 28 from rolling off the slag carrying mesh plate 24.

[0034] Specifically, Figure 6 As shown, the hook wheel 27 includes a sleeve 271 and a plurality of hook rods 272. The sleeve 271 is tightly sleeved on the second rotating shaft 26. One end of the hook rod 272 is fixedly connected to the sleeve 271. The other end of the hook rod 272 is bent to form a hook portion 273 for hooking the cross bar 28. The plurality of hook rods 272 are centrally symmetrically distributed with the central axis of the second rotating shaft 26 as the center. Figure 6 The straight arrow in the figure is the direction of water flow, and the arc arrow is the direction of rotation of the shaft 26. Most of the crossbar 28 comes from branches and rotten wood that fall into the river. The crossbar 28 is long, such as Figure 2 As shown, after the cross bar 28 enters the convergence area 56 along the water flow, it will be stuck in the convergence area 56 and collide with the guide mesh plate 1 20 and the guide mesh plate 21, and cannot enter the area between the upper surface slope 7 of the dam 1 and the pontoon 18. In addition, the cross bar 28 across the water surface of the convergence area 56 will prevent subsequent floating garbage from entering the area between the upper surface slope 7 of the dam 1 and the pontoon 18, affecting the automatic purification operation of the river water quality. Therefore, a hook wheel 27 is provided. Figure 6 As shown, the second rotating shaft 26 drives the plurality of hook wheels 27 to rotate, hook the cross bar 28 with the help of the hook portion 273, and bring the cross bar 28 away from the water surface, and then the cross bar 28 is lifted above the second rotating shaft 26. After the cross bar 28 passes directly above the second rotating shaft 26, the cross bar 28 rolls off the hook wheel 27 by itself, and finally falls onto the upper surface of the slag carrying mesh plate 24, as shown in FIG. Figure 2 As shown, the slag-carrying mesh plate 24 is tilted, with its high end close to the rotating shaft 26 and its low end close to the rear baffle 55. This design can prevent the cross bar 28 that falls onto the upper surface of the slag-carrying mesh plate 24 from remaining on the high end of the slag-carrying mesh plate 24 and affecting the rotation of the hook wheel 27. The high end of the slag-carrying mesh plate 24 is provided with a passing groove 25, and the passing groove 25 is for the hook rod 272 to pass through. After the cross bar 28 falls onto the upper surface of the high end of the slag-carrying mesh plate 24, the cross bar 28 rolls down to the lower end of the slag-carrying mesh plate 24 close to the rear baffle 55 by itself. The cross bar 28 does not block the passing groove 25 and does not affect the subsequent passage of the hook rod 272.

[0035] Further, such as Figure 2 As shown, a plurality of intervally arranged retaining rod piles 32 are provided downstream of the convergence area 56, the lower ends of the retaining rod piles 32 are located below the water surface of the river channel and are fixedly connected to the riverbed, and the upper ends of the retaining rod piles 32 are located above the water surface of the river channel. With this design, the retaining rod piles 32 can prevent the vertical rod 33 from rotating on the water surface, thereby ensuring that the cutter head 48 can smoothly cut off the vertical rod 33.

[0036] Specifically, Figure 2 As shown, a solar panel 34 is disposed on the upper surface of the buoyancy box 18 ; the solar panel 34 generates electricity to charge a battery 38 , and the battery 38 supplies power to electrical equipment in the buoyancy box 18 .

[0037] In this embodiment, if Figure 7 and Figure 8 As shown, a slider 35 is sealed and slidably installed at one end of the buoyancy box 18 near the protrusion 3. This design can prevent external river water from entering the buoyancy box 18. The sliding direction of the slider 35 is parallel to the moving direction of the buoyancy box 18; a pressure sensor 36, a fixing plate 45, a reduction motor 39, a spring three 47, a battery 38, and a control box 54 are fixedly installed in the buoyancy box 18. The pressure sensor 36 is connected to the slider 35 through a spring 37. The slider 35 slides in the buoyancy box 18 and compresses the spring 37. The pressure sensor 36 is used to detect the pressure of the spring 37 on it. When the buoyancy box 18 is blocked by the vertical rod 33 and cannot slide during the sliding process, the slider 35 slides relative to the buoyancy box 18 to squeeze the spring 37, so as to protect the purification module and prevent the buoyancy box 18, the rotating shaft 9 and the rotating shaft four 14, the driving wheel 12 and the driven wheel 13, and the crank 15 connecting rod 17 mechanism from being damaged. Figure 2 As shown in FIG. 1 , the difference between the vertical rod 33 and the horizontal rod 28 is their orientation in the water. The horizontal rod 28 is horizontal in the water, and there is a large angle between the length direction of the horizontal rod 28 and the water flow direction. On the contrary, the vertical rod 33 has a small angle between the length direction of the vertical rod 33 and the water flow direction. Therefore, one end of the vertical rod 33 can follow the water flow into the area between the upper surface slope 7 and the pontoon 18 of the dam 1. Figure 2 As shown, the vertical rod 33, like the horizontal rod 28, is mostly branches and rotten wood that have fallen into the river channel. It is relatively long and cannot be smoothly pushed into the slag hole 6 by the pontoon 18. One end of the vertical rod 33 follows the water flow into the area between the upper surface slope 7 of the dam 1 and the pontoon 18, which will affect the normal reciprocating sliding of the pontoon 18. Therefore, a cutter head 48 is required to cut the vertical rod 33 into multiple shorter sections so that it can be smoothly pushed to the slope 7 by the pontoon 18 and fall into the slag hole 6.

[0038] In this embodiment, if Figure 7 and Figure 8 As shown, the spring three 47 is located in the buoyancy box 18 at one end away from the protrusion one 3, the fixed plate 45 is provided with a spring two 44 on the side facing the spring three 47, and the spring two 44 is provided with a connecting plate 43 at one end away from the fixed plate 45. A slide rod 46 is slidably installed at one end of the buoyancy box 18 away from the protrusion one 3, one end of the slide rod 46 is located in the buoyancy box 18 and is fixedly connected to the connecting plate 43, and the other end of the slide rod 46 is located outside the buoyancy box 18 and is fixedly connected to a cutter head 48, as shown in FIG. Figure 2 , Figure 7 and Figure 8 As shown, the compressed spring 2 44 pushes the connecting plate 43 to move leftward close to the spring 3 47, and the movement of the connecting plate 43 drives the sliding rod 46 to slide, and the sliding rod 46 pushes the cutter head 48 to cooperate with the blocking rod pile 32 to cut off the vertical rod 33 extending into the area between the upper surface slope 7 of the dam 1 and the pontoon 18. Specifically, as shown in FIG. Figure 2 As shown, the cutter head 48 is pushed by the compressed spring 44 to quickly move left and hit the lower end of the vertical rod 33, causing the vertical rod 33 to rotate on the water surface. The upper end of the vertical rod 33 is blocked by the blocking rod pile 32 and cannot continue to rotate, and is then cut off by the cutter head 48.

[0039] Further, such as Figure 8 As shown, the slide rod 46 is also fixedly connected to the connecting plate 43 via a reinforcing rib 49 . This design enhances the connection strength between the slide rod 46 and the connecting plate 43 .

[0040] In this embodiment, if Figure 7 and Figure 8 As shown, the reduction motor 39 is transmission-connected with a screw rod 40, the screw rod 40 is rotationally connected to the buoyancy box 18, the screw rod 40 is connected to a control valve 41, the control valve 41 is slidingly connected to the inner wall of the buoyancy box 18, the reduction motor 39 drives the screw rod 40 to rotate and drive the control valve 41 to slide against the inner wall of the buoyancy box 18, a valve stem 42 is arranged in the control valve 41, the valve stem 42 can extend out of the control valve 41, the valve stem 42 extending out of the control valve 41 contacts the connecting plate 43, the control valve 41 slides against the inner wall of the buoyancy box 18 through the valve stem 42 to push the connecting plate 43 close to the fixed plate 45 and compress the spring 2 44. Specifically, as Fig. 9 As shown, the control valve 41 is provided with an electromagnet 50 and an annular plate 53, and the electromagnet 50 and the annular plate 53 are connected by a spring four 51. The end of the valve stem 42 extending into the control valve 41 is provided with an armature 52, and is fixedly connected to the annular plate 53. When the electromagnet 50 is energized, the armature 52 is attracted to approach, and the valve stem 42 is driven to retract into the control valve 41, and the spring four 51 is compressed at the same time. After the electromagnet 50 is powered off, the compressed spring four 51 quickly pushes one end of the valve stem 42 out of the control valve 41. After the electromagnet 50 is energized, the valve stem 42 quickly retracts into the control valve 41.

[0041] In this embodiment, if Figure 7 and Figure 8 As shown, when the float 18 is blocked by the vertical rod 33 and cannot slide, the slider 35 slides relative to the float 18 to squeeze the spring 1 37. At this time, the pressure sensor 36 detects an abnormal increase in pressure, and then the controller in the control box 54 controls the electromagnet 50 to energize so that the valve stem 42 quickly retracts into the control valve 41. Figure 7 and Figure 8The spring 2 44 under pressure pushes the connecting plate 43, the slide bar 46 and the cutter head 48 to slide rapidly to the left. The cutter head 48, in cooperation with the stop bar pile 32, cuts off one end of the vertical rod 33 extending into the area between the upper surface slope 7 of the dam 1 and the pontoon 18. The spring 3 47 buffers the connecting plate 43 to prevent it from rigidly colliding with the inner wall of the pontoon 18. After the electromagnet 50 is energized to rapidly retract the valve stem 42 into the control valve 41, the reduction motor 39 is started to drive the control valve 41 to move left to the working position. After the cutter head 48 cuts off the valve stem 42, the control valve 41 is moved to the working position. After the cross bar 28 is broken, the controller in the control box 54 controls the electromagnet 50 to cut off the power, one end of the valve stem 42 extends out of the control valve 41, and then the reduction motor 39 starts to drive the control valve 41 to move right, and with the help of the valve stem 42, the connecting plate 43 is moved to the left close to the fixed plate 45 and the spring 2 44 is compressed, waiting for the next time the buoy 18 is blocked by the vertical rod 33 and cannot slide, and then repeat the action to cut off the vertical rod 33 again, until the entire vertical rod 33 is cut into multiple sections and smoothly pushed into the slag drop hole 6 by the buoy 18.
