Description

Technical Field

[0001] This application relates to the field of aquatic plant control technology, and in particular to a wind and wave resistant floating shading plant control device. Background Technology

[0002] The weed removal vessel boasts a high degree of automation, operating along a pre-planned path. Based on sensor data such as latitude and longitude, speed, heading angle, cutting depth, draft, and obstacle distance, it adjusts the heading angle, speed, and cutting platform height in real time, activating the cutting and conveying devices to cut, remove, filter, and collect aquatic plants. Its advantages include a high degree of automation, efficient removal of large areas of aquatic plants, fast weed control, and long service life. However, its disadvantage is the need to purchase a separate weed removal vessel, resulting in a significant initial investment.

[0003] Among the environmental factors affecting aquatic plant growth, light intensity is relatively easy to control artificially. Both domestically and internationally, in-depth research has been conducted on shading techniques for controlling aquatic plants. Shading technology does not alter the hydrodynamic conditions or water quality of the water body; it only changes the necessary condition (light intensity) to achieve the goal of controlling aquatic plant growth. This technology is characterized by low investment, significant effects, and rapid results, meeting the requirements for emergency aquatic plant control and can be applied to practical engineering projects.

[0004] However, in the process of implementing the relevant technical solutions, at least the following technical problems were found: First, the existing methods of shading aquatic plants generally involve manually (using boats) covering the water surface with shade nets to shade the aquatic plants growing in the reservoir. This not only results in slow work efficiency, but also wastes manpower. Second, summer and autumn are the rapid growth periods for aquatic plants, and the intensity and duration of direct sunlight in summer and autumn are longer compared to spring and winter. Therefore, in summer and autumn, shade nets need to be applied in single-layer stacking, while in spring and winter, a single layer is sufficient to inhibit the growth of aquatic plants. Depending on the seasonal changes, manual stacking or removal is required, which consumes manpower and reduces the efficiency of shading aquatic plants. Summary of the Invention

[0005] This application provides a wind and wave resistant floating shading and weed control device, which solves the problems of existing technology where shading nets need to be installed manually and require different double or single layers depending on the season, affecting installation efficiency and labor costs.

[0020] This application discloses a wind and wave resistant floating shading and weed control device. The technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] To better understand the above technical solution, the following will provide a detailed explanation of the above technical solution in conjunction with the accompanying drawings and specific implementation methods. Example

[0022] Reference Figures 1-15A wind and wave resistant floating shading and weed control device includes a mounting frame 100 symmetrically installed on the bank and a support frame 200 located at the center of the water surface. Both the mounting frame 100 and the support frame 200 are rotatably mounted with drive wheels 10, which are driven to rotate by a first power device. A steel wire rope 20 for cyclic movement along the length of the water surface is rotatably connected to the drive wheel 10. The first power device is preferably an electric motor. The outer contour of the drive wheel 10 matches the steel wire rope 20, enabling the steel wire rope 20 to be confined within the drive wheel 10. Inside, to avoid misalignment during operation, and the wire rope 20 is treated with anti-corrosion to prevent rusting caused by exposure to the outdoors, and will also be maintained at certain intervals. The circulation length of the wire rope 20 can be reasonably designed according to the length of the water surface to be used. A shade net 30 is rotatably installed on the support frame 200 to achieve single / double layer shade coverage for aquatic plants to inhibit their growth. A single / double layer unwinding unit 1 is provided between the support frame 200 and the mounting frame 100, symmetrically arranged in the length direction of the water surface, for pulling the shade net 30 to unfold along the wire rope 20. The unwinding unit 1 includes a winding assembly 11 rotatably mounted on the support frame 200 for winding the shade net 30, and a traction assembly 12 on the wire rope 20 for moving the shade net 30 along the running direction of the wire rope 20, thereby unfolding the shade net 30 into a single or double layer. It should be noted that both the mounting frame 100 and the support frame 200 are equipped with fixing piles 21 at their bottoms, which can stably fix them to the shore and in the water.

[0023] Reference Figures 1-10The traction assembly 12 includes a movable frame 121 mounted on the wire rope 20 and fixed / detached by a clamping clip 122. The clamping clip 122 is rotatably mounted on the movable frame 121. An adjusting rod 123 is fixedly connected to the clamping clip 122. An abutment block 124 is fixedly connected to the end of the adjusting rod 123 away from the clamping clip 122. First elastic elements 125 are symmetrically rotatably connected to the movable frame 121. The first elastic elements 125 are installed in the mounting platform. One end of the mounting platform is movably connected to the movable frame 121. A pressing rod 126 is fixedly connected between the two sets of first elastic elements 125. The pressing rod 126 abuts and supports the adjusting rod 123. The pressing rod 126 is fixedly mounted on the end of the mounting platform away from the movable frame 121. A clamping member 3 is provided on the movable frame 121 near the first elastic element 125 for fixing the unfolded end of the shade net 30 and making the shade net 30 move with the movable frame 121. The moving frame 121 drives the moving frame 121 to move while disengaging the wire rope 20 through the rotary mechanism 4, so that the single-layer shade net 30 is stacked. The first elastic element 125 is preferably a spring. The material of this spring is alloy steel, which has the functions of general high fatigue and high elasticity, and has the advantage of easy replacement. After long-term use, the elastic element 125 can be easily replaced and rust-proofed. The clamping element 3 includes a mounting plate 31 installed on one side of the first gear 43 and the second gear 44. The mounting plate 31 is provided with a clamping plate 32. The clamping plate 32 is synchronously driven by a bidirectional transmission component to clamp and fix the unfolded end of the shade net 30. The bidirectional transmission component is preferably a bidirectional threaded rod and a moving block threaded on the bidirectional threaded rod. The moving block is fixedly connected to the clamping plate 32. The clamping plate 32 can adjust the distance on the bidirectional threaded rod through the moving block, so as to fix the shade net 30 and thus drive the shade net 30 to be rolled up. The rotary mechanism 4 includes a limiting rail 41 fixedly mounted on the mounting frame 100, and the limiting rail 41 is located outside the drive wheel 10. The limiting rail 41 includes a pressing part 411 and a releasing part 412. The pressing part 411 and the releasing part 412 are used to make the abutment block 124 contact the pressing part 411, thereby causing the adjusting rod 123 to rotate and the clamping clamp 122 to disengage from the wire rope 20. A drive rail 42 is fixedly connected to the mounting frame 100, and the drive rail 42 is located on one side of the drive wheel 10. The drive rail 42 has a toothed groove 421 fixedly connected along its track direction. The moving frame 121 A first gear 43 is rotatably mounted on the upper part of the moving frame 121 and is driven by a second power device, preferably an electric motor. A second gear 44 is rotatably mounted on the moving frame 121 and is located on the same horizontal line as the first gear 43. The second gear 44 is driven by a third power device. Both the first gear 43 and the second gear 44 are meshed with the tooth grooves 421 of the drive rail 42. A limit member 5 is provided between the second power device, the third power device and the drive rail 42. The third power device is preferably an electric motor. Both the second power device and the third power device are waterproof. It should be noted that during spring and winter, when the light intensity is weak, a single layer of shade net 30 is sufficient to inhibit the growth of aquatic plants. During summer and autumn, when the light intensity is strong, it is necessary to stack the single layer of shade net 30 to achieve the same effect of inhibiting the growth of aquatic plants. Furthermore, the shade net 30 should be set up higher, not touching the water surface, but 20-50cm away from the water surface. This will prevent the aquatic plants from directly touching the shade net 30, and leave a water channel in the middle to reduce the aquatic plants from being pushed and piled up.

[0024] During spring and winter: When the first power unit is started, the initial position of the moving frame 121 is located at the rotating shaft 111 of the winding shade net 30, and at this time, the unfolded end of the shade net 30 is inside the clamping member 3, that is, the unfolded end of the shade net 30 is fixed in the clamping member 3. When the first power unit is started, the drive wheel 10 rotates to move the steel wire rope 20 that drives it. When moving, the clamping clamp 122 clamped on its outside will move along the moving trajectory of the steel wire rope 20 with the moving frame 121, thereby driving the shade net 30 to unfold synchronously, and making its unfolding trajectory the same as the moving trajectory of the steel wire rope 20. When the shade net 30 can completely cover the water surface with a single layer, the first power unit is turned off, so that the shade net 30 only covers the water surface with a single layer. The first power unit drives the drive wheel 10 to rotate. In spring and winter, it only moves the clamp 122 and the moving frame 121 from the end near the unfolded shade net 30 to the shore. In summer and autumn, it moves the clamp 122 back to the end near the rotating shaft 111 of the shade net 30. This can be controlled by the circuit. During summer and autumn: The first power unit is activated again, and the clamping clamp 122 drives the moving frame 121 to gradually move to the position of the limiting track 41. At this time, the squeezing part 411 contacts the abutment block 124 and presses down the abutment block 124, causing the adjusting rod 123, which is fixedly connected to the abutment block 124, to rotate around the axis that is rotatably connected to the clamping clamp 122 and the moving frame 121. At this time, the first elastic element 125 is stretched, causing the clamping clamp 122 to disengage from the wire rope 20. Then, the second power unit is activated, causing the first gear 43 to rotate. The first gear 43 meshes with the tooth groove 421 of the drive track 42, ultimately causing the moving frame 121 and the clamping part 3 to move the sunshade net. The shade net 30 moves along the arc trajectory of the drive track 42, so that the shade net 30 can be stacked in a single layer. When the abutment block 124 moves again to disengage from the squeezing part 411, the abutment block 124 loses the squeezing of the squeezing part 411. Under the action of the restoring force, the first elastic element 125 drives the abutment block 124 to return to the initial position, and the adjusting rod 123 and the clamping clamp 122 are clamped onto the wire rope 20 again, so as to continue to unfold the shade net 30 following the running trajectory of the wire rope 20. At this time, the shade net 30 forms a double shading effect under the superposition effect, so that it can meet the reasonable treatment of the light intensity of the aquatic plant growth environment. Furthermore, when autumn transitions into winter, the first power unit can be reversed. When spring transitions into summer, the first power unit rotates forward, and the shade net 30 performs the aforementioned summer and autumn movements, causing the drive wheel 10 to rotate in the opposite direction, driving the wire rope 20 in the opposite direction. This causes the shade net 30 to be rolled up from a double-layer laying pattern to a single-layer pattern. At this time, the third power unit rotates, driving the second gear 44 to rotate along the tooth groove 421 of the drive track 42 until the clamping clamp 122 clamps the upper wire rope 20 again (since the first gear and the second gear are in the double-layer shade net 30, the second gear 44 is in front of the first gear 43, so when returning the shade net 30 to a single layer, the second gear 44 is started first). At this time, the first power unit is turned off, thus forming a single-layer shade net 30 coverage. The limiting member 5 includes a fixing plate 51 respectively installed on one side of the first power device and the second power device, and a limiting post 52 is fixedly installed at the bottom of the fixing plate 51. A limiting groove 53 is opened on the drive rail 42, and the limiting post 52 matches the limiting groove 53. A guide groove 54 is opened at the open end of the limiting groove 53. In order to make the running trajectory of the first gear 43 and the second gear 44 the same as that of the drive rail 42, the second power device and the third power device can move completely within the limiting groove 53 under the action of the limiting post 52 and the limiting groove 53. The guide groove 54 can guide the limiting post 52 and also make it easier for the limiting post 52 to enter the limiting groove 53. The winding assembly 11 includes a rotating shaft 111 mounted on a support frame 200, and the rotating shaft 111 is connected to the sunshade net 30 via a coil spring. A guide rod 112 is rotatably provided on the support frame 200 to guide the unfolded end of the sunshade net 30. The coil spring has a certain elasticity, which enables the sunshade net 30 to automatically retract onto the rotating shaft 111 when it changes from a double layer to a single layer. Example

[0025] Reference Figures 2-3 and Figure 10 A support assembly 2 is provided between the steel wire ropes 20 to support the shade net 30 located on the water surface. The support assembly 2 includes fixed piles 21 respectively fixedly installed on the mounting frame 100 and the support frame 200, and a nylon rope 22 is fixedly connected between the two sets of fixed piles 21. A support seat 23 is fixedly installed on the nylon rope 22, and multiple sets of support seats 23 are equidistantly arranged along the length direction of the nylon rope 22. A support rod 24 is fixedly connected between the support seats 23. When the shade net 30 is double-layered, the support rod 24 is located in the middle of the shade net 30. When the shade net 30 is single-layered, the support rod 24 is located at the bottom of the shade net 30. It can support the shade net 30 and prevent the shade net 30 from collapsing in the middle due to the long length of the steel wire ropes 20. The support seat 23 is hollow and has buoyancy, so it can float on the water surface when the water rises, so that it can also support the shade net 30 when the water rises. Example

[0026] Reference Figures 12-15Another set of steel wire ropes 20 is installed between the mounting frames 100. The two ends of each steel wire rope 20 are wound around a rotating shaft. When one set of steel wire ropes 20 is wound up, the other set is unwound. A collection box 201 is fixedly connected to one side of each steel wire rope 20. A retrieval frame 202 is rotatably connected to one side of the collection box 201 via a connecting rod. An opening and closing plate 203 is rotatably connected to the top of the retrieval frame 202. The opening and closing plate 203 is limited by a limiting component 6 for unloading the retrieved aquatic plants. The limiting component 6 includes a limiting block 61 installed at the bottom of the retrieval frame 202, and a second elastic element 62, preferably a spring, is installed inside the limiting block 61. The second elastic element 62 is connected to a blocking block 63, which is located on one side of the opening and closing plate 203 and used to block the opening and closing plate 203. A guide surface 631 is provided on one side of the blocking block 63. A trigger is provided between the blocking block 63 and the limiting block 61. The trigger is preferably a telescopic rod. An infrared sensor is installed on the side wall of the collection box 201. During the rotation of the connecting rod, it will gradually approach the infrared sensor. As the distance gets closer, the infrared sensor will transmit this electrical signal to the controller. The controller controls the telescopic rod (not shown in the figure) to retract, so that the blocking block 63 moves in the direction of compressing the second elastic member 62. This releases the blocking block 63 from the opening and closing plate 203. Under the action of gravity, the opening and closing plate 203 rotates to a state perpendicular to the water surface, so that the water plants in the retrieval frame 202 automatically fall from the retrieval frame 202 into the collection box 201, thereby completing the collection of water plants floating on the water surface. This can improve the efficiency of water plant removal and reduce the burden of manual retrieval. After the shade net 30 is used, the growth of aquatic plants can be inhibited. After the growth of aquatic plants is inhibited, not only will the growth be slow, but some aquatic plants will also have yellowing leaves, resulting in discarded yellow leaves. The yellow leaves are easy to float on the water surface due to decay. Under the action of the rotating shaft, the collection frame and the retrieval frame 202 move along the direction of the wire rope 20. During the movement, the retrieval frame 202 collects the discarded yellow leaves on the water surface. After collection, the connecting rod rotates. After the connecting rod rotates, it will drive the blocking block 63 to release the blocking effect on the opening and closing plate 203, thereby opening the opening and closing plate 203. With the tilting action of the retrieval frame 202, the waste leaves in the retrieval frame 202 are collected in a concentrated manner.

[0027] How this application works: An installation frame 100 is set up on the shore and a support frame 200 is set up in the center of the water surface. The first power device drives the drive wheel 10 to make the steel wire rope 20 move back and forth along the length of the water surface. This set of steel wire ropes 20 serves as the power traction line. The shade net 30 is wound on the rotating shaft 111 of the support frame 200. The shaft is equipped with a coil spring, which can automatically rebound and rewind. In spring and winter, the first power unit drives the steel wire rope 20 to move in a cycle. The moving frame 121 is fixed on the steel wire rope 20 by the clamping clamp 122 and moves synchronously. The clamping part 3 on the moving frame 121 clamps the end of the shade net 30. As the steel wire rope 20 is pulled, the shade net 30 is laid out in a single layer. After covering the area, the machine stops, realizing single-layer shading and weed control. In summer and autumn, when the mobile frame 121 reaches the shore-side limiting track 41, the squeezing part 411 presses against the abutment block 124, causing the adjusting rod 123 to change angle, which causes the clamping clamp 122 to loosen and connect with the wire rope 20. The first gear 43 on the mobile frame 121 meshes with the tooth groove 421 of the drive track 42 and moves along the arc trajectory, causing the unfolded shade net 30 to fold back and overlap. After reaching the track disengagement part 412, the abutment block 124 resets, and the clamping clamp 122 re-clamps the wire rope 20, continuing to pull to form a double-layer shade coverage. When the season changes, the drive wheel 10 reverses, and in conjunction with the second gear 44, the double-layer net can be rolled back to a single layer.

[0028] Fixing stakes 21 and nylon ropes 22 are installed between the mounting frame 100 and the support frame 200. Support seats 23 are arranged at equal intervals on the nylon ropes 22, and support rods 24 are connected between the support seats 23 to support the shade net 30. When it is a single layer, the support rods 24 support the net from below. When it is a double layer, the support rods 24 provide support between the two layers of net to prevent the net from collapsing in the middle, touching the water, or getting caught on aquatic plants due to its large span. After the weeds are controlled by shading, the withered yellow leaves of aquatic plants will float on the water surface. Another set of circulating steel wire ropes 20 drives the collection box 201 and the retrieval frame 202 to move synchronously. The retrieval frame 202 automatically scoops up the remaining leaves of aquatic plants on the water surface while moving. After it is full, the connecting rod rotates to trigger the infrared sensor. The sensor signal controls the telescopic rod to retract, compressing the second elastic element 62, causing the blocking block 63 to retract and release the restriction on the opening and closing plate 203. The opening and closing plate 203 flips open under gravity, and the remaining leaves of aquatic plants in the retrieval frame 202 are automatically poured into the collection box 201 for centralized collection, completing the automatic cleaning of the remaining leaves.
