Description

Technical Field

[0001] The present invention relates to the field of water conservancy projects, and in particular to a device and method for managing the water environment of rivers and lakes. Background Art

[0002] There are many rivers and tributaries distributed across the land of our country. The distribution of rivers in different regions is different. In order to facilitate the use of water resources in water-scarce areas, many canals and rivers have been built since ancient times to ensure normal water use in all regions.

[0003] Water-friendly trails are usually set up on both sides of the river for convenient viewing of the river landscape, which makes it easy for some floating objects such as domestic garbage to appear in the river. Too much garbage and floating objects not only affect the beauty of the river, but also cause pollution of the river water and blockage of the river. Therefore, floating garbage on the surface of the river must be cleaned regularly, and manual salvage and cleaning is time-consuming and labor-intensive. Therefore, most people currently choose to lay garbage buoys or garbage nets on the river surface to intercept floating garbage, which is convenient for centralized cleaning. However, in actual use, floating garbage will accumulate along the garbage buoys and garbage nets, and when cleaning, manual handheld scoop nets are required to salvage them, which not only affects the beauty of the river, but also does not bring convenience to cleaning, so it needs to be improved.

[0015] Preferably, the top end diameter of the spring is smaller than the bottom end diameter.

[0016] A method for treating the water environment of rivers and lakes, using the above-mentioned equipment for treating the water environment of rivers and lakes, comprises the following steps:

[0017] S1: Before installing the trash chain, first install a pair of U-shaped frames on both sides of the river channel, connect the connecting rods at the ends of the trash chain to the ear blocks with bolts, then slide the mounting rods on the U-shaped frames, adjust the position of the floating debris collection port, and then install a net bag on the baffle at the collection port to collect floating debris;

[0018] S2: The trash chain is installed obliquely on the river channel. Several impellers are driven to rotate by the downstream river water, driving the scrapers on the side wall of the first floating plate to send floating debris on the river surface into the floating debris collection port;

[0019] S3: When floating objects are blocked in the grooves of the scraper and the trash retaining plate, the impeller will still generate thrust under the water flow speed, so that the scraper pushes the floating objects to collide with the bending part, and the bending part is driven by the force to drive the mounting plate to rotate around the rotating shaft. When the mounting plate rotates, the second trigger part is pulled by the pull rope to slide in the fixed box until it contacts the first trigger part. At this time, the electric push rod is activated, and the output end extends outward, pushing the trash retaining plate to rotate, so that the trash retaining plate pushes out the blocked floating objects, thereby achieving the blockage effect.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, a pollution-blocking chain consisting of a floating plate, an impeller and an ecological floating bed is installed on the river channel. The first floating plate is driven by the water flow to rotate, and the floating objects floating on the river surface are sent to one side of the river channel for centralized collection. Compared with the current method of installing pollution-blocking floats and pollution-blocking nets, floating objects tend to accumulate along the pollution-blocking floats and pollution-blocking nets, requiring manual hand-held scoop nets to salvage, which is very inconvenient. In this application, floating objects are collected on one side of the river bank, which is convenient for manual collection, salvage and cleaning.

[0022] By setting up a blocking component, the first float can be prevented from being blocked when it rotates and transports floating objects in the water body, thereby reducing the frequency of manual maintenance. The blocking component is powered by solar panels, which effectively saves energy, is easy to operate, and has a simple and effective structure. When floating objects are blocked at the bending part, the first float still generates thrust through the water speed, which drives the bending part to rotate around the rotating shaft. When the mounting plate on the bending part pulls the elastic rope through the first positioning rod, it also pulls the pull rope through the sleeve. The pull rope causes the second trigger part to slide in the fixed box until it contacts the first trigger part. The first trigger part and the second trigger part are both metal contacts. After contact, the electric push rod is triggered to start, driving the garbage blocking plate to rotate, and separating the floating objects from the scraper, thereby avoiding the scraper from stagnating on the water surface due to the blockage of floating objects and being unable to transport floating objects, achieving the effect of automatic blocking, eliminating the need for manual blocking maintenance, and saving manpower.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 4As shown, an embodiment of the present invention provides a river and lake water environment treatment device, including a pollution-blocking chain composed of a plurality of second floating plates 4, connecting bent rods 14, fixed rods 11 and positioning modules. A plurality of ecological floating beds 5 for cultivating hydroponic plants are fixedly installed on the top of the second floating plates 4 by bolts. By setting up the ecological floating beds 5, the landscape and water body restoration are combined, and the device has the dual functions of water purification and landscaping. Both ends of the pollution-blocking chain are fixedly connected to the river bank through the positioning module. The bottom rotating sleeve of the second floating plate 4 A first floating plate 1 is connected to drive floating objects through water flow, and a blocking component is installed on the fixed rod 11 to prevent floating objects from being entangled with the first floating plate 1. The present application installs a pollution-blocking chain composed of a floating plate, an impeller 2 and an ecological floating bed 5 on the river channel. The first floating plate 1 is driven to rotate by the water flow to send floating objects floating on the river surface to one side of the river channel for centralized collection. Compared with the current method of installing pollution-blocking floats and pollution-blocking nets, floating objects are easily accumulated along the pollution-blocking floats and pollution-blocking nets, and need to be manually salvaged with a handheld scoop net, and the aesthetics is poor.

[0037] like Figure 1 、 Figure 10 and Figure 11 As shown, the positioning module includes a U-shaped frame 8 fixedly mounted on the side wall of the river bank, and a mounting rod 10 is movably mounted on the U-shaped frame 8. A second buoy 35 is sleeved on the U-shaped frame 8 and the mounting rod 10. A pair of mounting ears are fixedly mounted on the side walls of the second buoy 35, and a pair of ear blocks 37 are fixedly mounted on the side walls of one of the second buoys 35. The ends of the ear blocks 37 are rotatably connected to the connecting bent rod 14. By setting the U-shaped frame 8, the pollution chain can be installed above the river surface. By sliding the mounting rod 10, the position of the floating object collection port can be conveniently set according to actual use requirements. The setting of the second buoy 35 can facilitate the adjustment of the baffle 9 and the first floating plate 1 as the river surface rises and falls.

[0038] like Figure 1 、 Figure 10 and Figure 11 As shown, the trash chain is set at an angle, and one end of the trash chain forms an angle with the river bank. The smaller angle on the downstream side of the river is the floating object collection port. The advantage of this setting is that it avoids the accumulation of floating objects along the trash chain and collects the floating objects to the side of the river bank, which is convenient for manual collection, salvage and cleaning. A pair of second buoys 35 located at the collection port are movably installed with the same insertion rod 34 through the mounting ears. An L-shaped rod 38 is fixedly installed on the side wall of the insertion rod 34, and a baffle 9 is fixedly installed on the L-shaped rod 38. The top and bottom of the baffle 9 are both equipped with movable nails 36 for fixing the net bag. By installing the net bag on the baffle 9, the floating objects are collected in the net bag, and there is no need for manual hand-held scoop net salvage, which is convenient for cleaning, reduces the labor intensity of manual labor, and saves manpower.

[0039] like Figure 1-Figure 3As shown, the first floating plate 1 is rotatably installed below the second floating plate 4, and a slide groove is provided on the side wall of the first floating plate 1. A number of racks 12 are fixedly connected to the side wall of the second floating plate 4 in a uniform circle. A ball head 13 is fixedly installed at the end of the rack rod 12, and the ball head 13 is in contact with the slide groove. The advantage of this arrangement is that the first floating plate 1 can be positioned, and the second floating plate 4 does not rotate with the first floating plate 1. A number of scrapers 3 are fixedly connected to the first floating plate 1 in a uniform circle. The bottom of the scraper 3 is integrally formed with a tossing wing. By setting the tossing wing, the range of the scraper 3 rotating to toss the water body can be expanded. An impeller 2 is fixedly installed at the bottom of the first floating plate 1. The impeller 2 can provide driving force for the first floating plate 1 through the water flow, so that several first floating plates 1 rotate simultaneously on the water surface to form a floating object conveying chain;

[0040] like Figure 2-Figure 7 As shown, a rotating shaft is rotatably sleeved between an adjacent pair of fixed rods 11, and a plurality of dirt-blocking plates 7 evenly arranged in a circumference are fixedly installed on the side wall of the rotating shaft. A plurality of drain holes are provided on the dirt-blocking plates 7. The advantage of such a setting is that the resistance of the water flow is reduced. A groove for accommodating the scraper 3 is provided on the side wall of the dirt-blocking plate 7 to provide a rotation space for the scraper 3. A bending part 15 is also rotatably installed on the rotating shaft through an elastic member, and a mounting plate 20 is fixedly installed on one end of the bending part 15. The blocking component includes a mounting frame 16 fixedly installed on the fixed rod 11, a substrate 17, a solar cell panel 6 and a driving module fixedly installed on the substrate 17. The mounting frame 16 is formed into a whole by bending. Type, a first buoy 18 is rotatably installed at the central position of the mounting frame 16. The advantage of this arrangement is that it can increase the buoyancy of the mounting frame 16 and provide stable support for the blockage removal component. The driving module is connected to the trash retaining plate 7 so that after the floating object collides with the bending part 15, the scraper 3 pushes the bending part 15 to rotate, and the driving module is started by the pull rope 31 to push the trash retaining plate 7 to rotate to complete the blockage. In this application, by setting up a blockage removal component, it is possible to avoid blockage when the first float 1 rotates to transport floating objects in the water body, thereby reducing the frequency of manual maintenance. The blockage removal component is powered by the solar panel 6, which effectively saves energy, is easy to operate, and has a simple and effective structure.

[0041] like Figure 7-Figure 9As shown, a bending section 26 is integrally formed on the side wall of the base plate 17. This arrangement can effectively save materials and equipment investment costs. The driving module includes a battery box 25, a fixing box 28 fixedly mounted on the battery box 25, and an electric push rod 27 rotatably mounted on the bending section 26. A positioning pin 22 is fixedly mounted on the top of the dirt-blocking plate 7. The output end of the electric push rod 27 extends to the positioning pin 22 for rotational connection. When the electric push rod 27 drives the output end to extend, the positioning pin 22 can be used to push the dirt-blocking plate 7 to rotate around. The dirt-blocking plate 7 on the side blocked by the scraper 3 pushes the floating objects to disperse from the scraper 3, thereby preventing the scraper 3 from stagnating on the water surface due to the blockage of floating objects and being unable to transport the floating objects.

[0042] like Figure 5 and Figure 7 As shown, a first positioning rod 21 is fixedly installed on the top of the mounting plate 20, and a second positioning rod 23 is fixedly installed on the bottom of the fixing rod 11. A mounting groove is provided at the central position of the first positioning rod 21 and the second positioning rod 23, and the elastic component is an elastic rope 19, which is sleeved on the mounting grooves of the first positioning rod 21 and the second positioning rod 23. A sleeve 24 is fixedly installed on the top of the first positioning rod 21, and the sleeve 24 is connected to the driving module through a pull rope 31. By setting the elastic rope 19, when the bending part 15 is rotated by the thrust of the scraper 3, it will drive the first positioning rod 21 away from the second positioning rod 23, and after the floating objects are dispersed by the blocking component and the scraper 3, the bending part 15 will rebound and reset through the elastic rope 19. The top diameter of the first positioning rod 21 is larger than the bottom diameter. When the top of the first positioning rod 21 contacts the fixing rod 11, the mounting plate 20 is positioned. The structure is simple, the cost is low, and it is convenient for disassembly and subsequent maintenance.

[0043] like Figure 8As shown, a fixing box 28 is fixedly installed on the side wall of the battery box 25, and a first trigger member 29 electrically connected to the electric push rod 27 is fixedly installed on the inner wall of the fixing box 28. A second trigger member 32 is slidably installed in the inner cavity of the fixing box 28, and a spring 33 is fixedly installed between the second trigger member 32 and the first trigger member 29. The top diameter of the spring 33 is smaller than the bottom diameter. The advantage of this arrangement is that it can reduce the distance after the spring 33 is compressed. A guide rod 30 is fixedly installed on the side wall of the first trigger member 29, and a pull rope 31 is fixedly installed on the side wall of the second trigger member 32. The pull rope 31 passes through the guide rod 30 and extends to be fixedly connected to the sleeve 24. When floating objects are blocked in the bending member 15, the first float 1 still generates thrust through the water speed, which drives the bending part 15 to rotate around the rotating shaft. When the mounting plate 20 on the bending part 15 pulls the elastic rope 19 through the first positioning rod 21, it also pulls the pull rope 31 through the sleeve 24. The pull rope 31 causes the second trigger part 32 to slide in the fixing box 28 until it contacts the first trigger part 29. The first trigger part 29 and the second trigger part 32 are both metal contacts. After contact, the electric push rod 27 is triggered to start, driving the dirt blocking plate 7 to rotate, and separating the floating objects from the scraper 3, thereby preventing the scraper 3 from stagnating on the water surface due to the blockage of floating objects and being unable to transport the floating objects, thereby achieving the effect of automatic blockage removal, eliminating the need for manual blockage removal and maintenance, and saving manpower.

[0044] A method for treating the water environment of rivers and lakes, using the above-mentioned equipment for treating the water environment of rivers and lakes, comprises the following steps:

[0045] S1: Before installing the trash chain, first install a pair of U-shaped frames 8 on both sides of the river channel, and connect the connecting bent rods 14 at the ends of the trash chain to the ear blocks 37 with bolts. Then, slide the mounting rods 10 on the U-shaped frames 8, adjust the position of the floating debris collection port, and then install a net bag on the baffle 9 at the collection port to collect floating debris;

[0046] S2: The trash chain is installed obliquely on the river channel. The impellers 2 are driven to rotate by the downstream river water, driving the scrapers 3 on the side walls of the first floating plate 1 to send the floating debris on the river surface into the floating debris collection port;

[0047] S3: When floating objects are blocked in the grooves of the scraper 3 and the trash retaining plate 7, the impeller 2 will still generate thrust under the water flow speed, so that the scraper 3 pushes the floating objects to collide with the bending part 15, and the bending part 15 is driven by the force to drive the mounting plate 20 to rotate around the rotating shaft. When the mounting plate 20 rotates, the second trigger part 32 is pulled by the pull rope 31 to slide in the fixed box 28 until it contacts the first trigger part 29. At this time, the electric push rod 27 is started, and the output end extends outward, pushing the trash retaining plate 7 to rotate, so that the trash retaining plate 7 pushes out the blocked floating objects, thereby achieving the blockage effect.

[0048] By installing a pollution-blocking chain consisting of a float, an impeller 2 and an ecological floating bed 5 on the river channel, the first float 1 is driven to rotate by the water flow, and the floating objects floating on the river surface are sent to one side of the river channel for centralized collection. Compared with the current method of installing pollution-blocking floats and pollution-blocking nets, floating objects are easily accumulated along the pollution-blocking floats and pollution-blocking nets, and manual hand-held scoop nets are required to salvage them, which is very inconvenient to operate. The present application collects floating objects to one side of the river bank, which is convenient for manual collection, salvage and cleaning, and a blocking component is provided to avoid blockage when the first float 1 rotates and transports floating objects in the water body, thereby reducing the frequency of manual maintenance. The blocking component is powered by solar panels 6, which effectively saves energy, is easy to operate, and has a simple and effective structure. When floating objects are blocked at the bending part 15, the first float 1 still generates thrust through the water speed, which drives the bending part 15 to rotate around the rotating shaft. When the mounting plate 20 on the bending part 15 pulls the elastic rope 19 through the first positioning rod 21, it also pulls the pull rope 31 through the sleeve 24. The pull rope 31 causes the second trigger part 32 to slide in the fixing box 28 until it contacts the first trigger part 29. The first trigger part 29 and the second trigger part 32 are both metal contacts. After contact, the electric push rod 27 is triggered to start, driving the dirt blocking plate 7 to rotate, and separating the floating objects from the scraper 3, thereby preventing the scraper 3 from stagnating on the water surface due to the blockage of floating objects and being unable to transport the floating objects, thereby achieving the effect of automatic blockage removal, eliminating the need for manual blockage removal and maintenance, and saving manpower.
