Description

Technical Field

[0001] This invention relates to the field of aquatic ecosystem restoration equipment technology, specifically an adjustable spawning ground with anti-countermeasures capabilities. Background Technology

[0002] After the hydropower station is built and put into operation, the dam blocks the natural connectivity of the river, preventing fish downstream from migrating to suitable habitats upstream for spawning and reproduction. Constructing artificial spawning grounds within the reservoir can provide fish with the necessary breeding environment. Building artificial spawning grounds through local habitat creation techniques such as artificial fish nests is one of the important measures to reduce the impact of water conservancy and hydropower projects on river fish ecology and restore fish ecological resources. Artificial fish nests are facilities that simulate the fish ecological environment, are artificially constructed using alternative materials, and are set in specific water areas to provide a place for fish to spawn, reproduce, and for juvenile fish to inhabit and grow. They are made of soft, finely branched natural or artificial materials to provide a large attachment area and are designed specifically for fish that lay adhesive eggs on aquatic plants, which need to be attached to a flexible substrate such as aquatic plants to hatch.

[0003] Existing artificial fish nests typically employ floating frame structures, where aquatic plants are bound within a frame made of buoyant materials such as bamboo and fixed to shallow water islands. The buoyant frame is primarily made of bamboo, secured in a rectangular shape using wire and rope. By binding aquatic plants and other substrate materials within the frame, the success rate of fish reproduction can be effectively increased, enhancing the stability of the reservoir's ecosystem. However, when binding the aquatic plants, tight binding can cause most of the plants to clump together, reducing the area where fish eggs can attach and thus decreasing spawning efficiency. While loose binding is beneficial for fish spawning, during windy or rainy weather, greater water surface fluctuations can cause the aquatic plants to be washed away by waves, further reducing spawning efficiency.

[0004] It is concluded that existing technologies have difficulty in adaptively adjusting the tightness of the binding of aquatic plants according to the size of the water waves. Therefore, this invention makes an innovative design for an adjustable spawning ground with anti-countermeasures capabilities. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide an adjustable spawning ground with anti-countermeasures capabilities, thereby solving the problem mentioned in the background technology that it is difficult to adaptively adjust the tightness of the binding of aquatic plants according to the size of the water waves.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable spawning ground with anti-resistance function, including an anchor rod, a suspension frame disposed outside the anchor rod, and a suspension plate disposed outside the suspension frame, and further including an anti-resistance plate evenly distributed outside the suspension plate to adaptively reduce the fluffiness of aquatic plants based on the size of water waves, a fixing cylinder evenly distributed on the inner wall of the anti-resistance plate for positioning aquatic plants, a tightening component disposed on the fixing cylinder to adaptively adjust the tightness of binding aquatic plants based on the size of water waves, and a guide rod evenly distributed on the outer wall of the suspension frame to adaptively drive the tightening component to bind aquatic plants based on the size of water waves;

[0007] The tightening component includes a binding hook that adaptively tightens aquatic plants based on the size of the water waves;

[0008] The top of the suspension plate is provided with a limiting slide at an equal angle for driving the tightening component to tighten simultaneously.

[0009] Preferably, a limiting plate is fixedly connected to the top of the anchor rod, and a tapered anchor is provided at the bottom of the anchor rod;

[0010] The suspended frame is shaped like a "U" and the anchor rod is a rectangular rod. The inner wall of the suspended frame is slidably connected to the outer wall of the anchor rod.

[0011] Preferably, the suspension plate is in the shape of a "ring" structure, and a first spring is fixedly installed on the inner wall of the suspension plate, with one end of the first spring fixedly connected to the outer wall of the suspension frame.

[0012] Preferably, the limiting slide is an arc-shaped structure, and a slide rod is slidably connected to the inner wall of the limiting slide.

[0013] Preferably, a drive rod is fixedly connected to the outer wall of the slide rod, and one end of the drive rod is fixedly connected to the outer wall of the fixed cylinder.

[0014] Preferably, the tightening component further includes a mounting bracket fixedly installed at the bottom of the fixed cylinder, a second spring fixedly installed inside the mounting bracket, a guide block fixedly connected to the top of the second spring, and the top of the guide block fixedly connected to the bottom of the binding hook.

[0015] The outer wall of the fixed cylinder is provided with a channel, and the outer wall of the guide block is slidably connected to the inner wall of the channel;

[0016] The binding hook is shaped like a "hook", with its top extending through a channel and reaching the outside of the fixing cylinder.

[0017] Preferably, the inner wall of the fixed cylinder is provided with a sliding groove, and the end of the guide rod away from the suspension frame passes through the sliding groove and extends into the interior of the fixed cylinder;

[0018] The guide rod has a movable shaft at one end near the suspension frame, and the movable shaft is installed on the outer wall of the suspension frame.

[0019] Preferably, the outer wall of the guide block is provided with a guide groove, and the inner wall of the guide groove is an inclined surface.

[0020] Preferably, the bottom of the guide rod is provided with grooves at equal intervals, and the guide rod passes through the guide slot through the grooves.

[0021] Preferably, the outer wall of the fixed cylinder is provided with a slide rail, and the inner wall of the slide rail is slidably connected to a slider. The outer wall of the slider is fixedly installed with a support frame, and the support frame is rotatably connected to a limit plate via a rotating shaft.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention employs equidistantly distributed fixing cylinders to install aquatic plants. The equally distributed anti-waterproof plates are located on the outermost side. When impacted by water waves, the distance between adjacent anti-waterproof plates decreases or even merges, forming a closed loop that protects the aquatic plants inside. Furthermore, the fixing cylinders simultaneously tighten the aquatic plants with a shrinking component, preventing them from being washed away and scattered. Compared to existing spawning ground technologies, this invention has the advantage of adaptively adjusting the tightness of the binding according to the size of the water waves, enhancing the anti-waterproofing effect of the spawning ground and improving spawning efficiency.

[0024] As the equally angled anti-aircraft plates move towards the suspension plate, they simultaneously drive multiple fixed cylinders to move. The fixed cylinders mirrored on both sides are limited by the limiting plates and move towards the middle fixed cylinder. Therefore, the mirrored fixed cylinders on both sides will cause the aquatic plants to gather on the middle fixed cylinder, making the aquatic plants "clump together". This prevents the fish eggs on the aquatic plants from being washed away by the waves and further prevents the aquatic plants from being scattered and falling. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 9 The present invention provides a technical solution: an adjustable spawning ground with anti-resistance function, including an anchor 1, a suspension frame 2 set outside the anchor 1, and a suspension plate 4 set outside the suspension frame 2. The invention is characterized by further including an anti-resistance plate 5 evenly distributed at an angle outside the suspension plate 4 to adaptively reduce the fluffiness of aquatic plants based on the size of water waves, a fixing cylinder 6 evenly distributed at an angle on the inner wall of the anti-resistance plate 5 for positioning aquatic plants, a tightening component set on the fixing cylinder 6 to adaptively adjust the tightness of binding aquatic plants based on the size of water waves, and a guide rod 7 evenly distributed at an angle on the outer wall of the suspension frame 2 to adaptively drive the tightening component to tighten aquatic plants based on the size of water waves.

[0037] The tightening components include a binding hook 64 that adaptively tightens aquatic plants based on the size of the water waves;

[0038] The top of the suspension plate 4 is provided with a limiting slide 41 at an equal angle for driving the tightening component to tighten simultaneously.

[0039] In this embodiment, the aquatic plants are tied to the top of the fixed tube 6 by the binding hook 64. The aquatic plants can float loosely on the water surface, providing spawning conditions for fish. The anti-floating plate 5 has an arc-shaped structure, and there are multiple anti-floating plates 5. The multiple anti-floating plates 5 are distributed at equal angles on the outside of the suspension plate 4, and there are gaps between adjacent anti-floating plates 5. When the water surface is not large, the water flow can flow through the gaps to the aquatic plants, increasing the water flow and promoting the proliferation of plankton.

[0040] A limit plate is fixedly connected to the top of the anchor rod 1, and a tapered anchor is provided at the bottom of the anchor rod 1;

[0041] In this embodiment, the anchor rod 1 is fixed underwater by installing a conical anchor at its bottom. The top of the anchor rod 1 extends above the water surface. The suspension frame 2, suspension plate 4, anti-resistant plate 5, and fixing cylinder 6 are all suspension materials that can float on the water surface and can adaptively adjust their positions according to the rise and fall of the water surface to always remain suspended on the water surface. The diameter of the limiting plate at the top of the anchor rod 1 is larger than the diameter of the suspension frame 2. The limiting plate at the top of the anchor rod 1 can limit the suspension frame 2 and prevent the suspension frame 2 from detaching from the anchor rod 1. An appropriate amount of aquatic plants are placed inside the binding hook 64. The binding hook 64 can fix the aquatic plants. At this time, the aquatic plants are in a relatively loose state, which is conducive to the attachment of fish eggs.

[0042] The suspended frame 2 has a "U" shaped structure, and the anchor rod 1 is a rectangular rod. The inner wall of the suspended frame 2 is slidably connected to the outer wall of the anchor rod 1.

[0043] In this embodiment, the suspended frame 2 is limited by the outer wall of the anchor rod 1 and cannot rotate on the anchor rod 1; the suspended frame 2 can only move up and down on the anchor rod 1.

[0044] The suspension plate 4 is in the shape of a "ring". A first spring 3 is fixedly installed on the inner wall of the suspension plate 4, and one end of the first spring 3 is fixedly connected to the outer wall of the suspension frame 2.

[0045] In this embodiment, since the suspended frame 2 is limited by the outer wall of the anchor rod 1 and cannot rotate on the anchor rod 1, the suspended plate 4 will stretch the first spring 3 when it is subjected to a force to rotate. When the suspended plate 4 is not subjected to external force, it will be reset by the first spring 3.

[0046] The limiting slide 41 has an arc-shaped structure, and a slide rod 42 is slidably connected to the inner wall of the limiting slide 41.

[0047] In this embodiment, when the slide bar 42 moves toward the suspension frame 2, the suspension plate 4 will rotate due to the arc structure of the limiting slide 41. The rotation of the suspension plate 4 will cause other slide bars 42 to slide inside the limiting slide 41. When one slide bar 42 moves inside the suspension frame 2, it will drive multiple slide bars 42 to rotate together through the rotation of the suspension plate 4.

[0048] A drive rod 43 is fixedly connected to the outer wall of the slide rod 42, and one end of the drive rod 43 is fixedly connected to the outer wall of the fixed cylinder 6.

[0049] In this embodiment, when the anti-water plate 5 is impacted by water waves, it will cause the fixed cylinder 6 to move towards the suspension plate 4. The fixed cylinder 6 can then drive the sliding rod 42 to move towards the suspension plate 4 via the drive rod 43. Since the movement trajectory of the sliding rod 42 is straight, while the limiting slide 41 is arc-shaped, the sliding rod 42 will drive the suspension plate 4 to rotate via the limiting slide 41 when it moves. When the suspension plate 4 rotates, it will drive the corresponding internal sliding rod 42 to move towards the suspension frame 2 via other limiting slides 41, thereby driving the anti-water plates 5 in other directions to move towards the suspension plate 4 together. This achieves that when the anti-water plate 5 in one direction is impacted by water waves, the anti-water plates 5 distributed at equal angles will move together, the distance between adjacent anti-water plates 5 will decrease or even merge together, reducing the impact of water waves on aquatic plants.

[0050] Please see Figures 1 to 9 The tightening component also includes a mounting bracket 61 fixedly installed at the bottom of the fixed cylinder 6. A second spring 62 is fixedly installed inside the mounting bracket 61. A guide block 63 is fixedly connected to the top of the second spring 62. The top of the guide block 63 is fixedly connected to the bottom of the binding hook 64.

[0051] The outer wall of the fixed cylinder 6 has a channel, and the outer wall of the guide block 63 is slidably connected to the inner wall of the channel;

[0052] The binding hook 64 is shaped like a "hook" and its top extends through the channel to the outside of the fixing cylinder 6.

[0053] In this embodiment, the binding hook 64 ties the aquatic plants to the top of the fixing cylinder 6, allowing the aquatic plants to float loosely on the water surface, providing spawning conditions for fish. The binding hook 64 is limited by the second spring 62, which can limit the aquatic plants.

[0054] The inner wall of the fixed cylinder 6 is provided with a sliding groove, and the end of the guide rod 7 away from the suspension frame 2 passes through the sliding groove and extends into the interior of the fixed cylinder 6;

[0055] A movable shaft is provided at one end of the guide rod 7 near the suspension frame 2, and the movable shaft is installed on the outer wall of the suspension frame 2.

[0056] In this embodiment, when the fixed cylinder 6 moves toward the suspended frame 2, the fixed cylinder 6 will move on the guide rod 7, so that the end of the guide rod 7 extending into the fixed cylinder 6 will move further into the fixed cylinder 6.

[0057] The outer wall of the guide block 63 is provided with a guide groove, and the inner wall of the guide groove is a slope.

[0058] The bottom of the guide rod 7 is provided with grooves 71 at equal intervals, and the guide rod 7 passes through the guide through grooves 71.

[0059] In this embodiment, when the anti-water plate 5 is impacted by water waves and moves towards the suspension plate 4, the end of the guide rod 7 extending into the fixed cylinder 6 will move further into the fixed cylinder 6. The force exerted by the guide rod 7 when it moves will drive the guide block 63 to move downward along the inclined surface inside the guide groove, thus driving the binding hook 64 to move downward, reducing the space for binding aquatic plants, and making the aquatic plants more tightly bound.

[0060] The outer wall of the fixed cylinder 6 is mirror-image-opened with a slide rail, and the inner wall of the slide rail is slidably connected to a slider. The outer wall of the slider is fixedly installed with a support frame, and the support frame is rotatably connected to a limit plate via a rotating shaft.

[0061] In this embodiment, the inner wall of the anti-resistant plate 5 is provided with a sliding track, and a sliding frame is slidably installed on the inner wall of both sliding tracks. A fixed cylinder 6 is installed at one end of the sliding frame. The fixed cylinder 6 is also provided with a tightening component and a control component. The guide rod 7 on the control component is rotatably installed on the outer wall of the suspension frame 2 at the end away from the fixed cylinder 6. The two fixed cylinders 6 are provided with the same sliding track on their opposite sides, and the same support frame is slidably installed on the inner wall of the sliding track. The support frame is rotatably connected to the other end of the limiting plate through a rotating shaft. Therefore, the two limiting plates can respectively limit the two mirrored fixed cylinders 6. When the anti-resistant plates 5 are moved at equal angles, the mirrored fixed cylinders 6 will move towards the middle fixed cylinder 6 due to the limitation of the limiting plates. Therefore, the mirrored fixed cylinders 6 on both sides will drive the aquatic plants to gather on the middle fixed cylinder 6, thereby protecting the aquatic plants.

[0062] Working principle: When there is wind, rain, or other conditions that cause large water surface fluctuations, the waves will first impact the outermost anti-water barrier 5. The anti-water barrier 5 drives the fixed cylinder 6 to move towards the suspension plate 4. When the fixed cylinder 6 moves, it drives the sliding rod 42 to slide inside the limiting slide 41 via the drive rod 43. The limiting slide 41 has an arc-shaped structure, which allows the sliding rod 42 to drive the suspension plate 4 to rotate through the limiting slide 41. When the suspension plate 4 rotates, the limiting slide 41 on its surface will drive other sliding rods 42 to move towards the suspension frame 2. Thus, multiple sliding rods 42 can drive multiple fixed cylinders 6 to move towards the suspension plate 4, so that the anti-water barriers 5 distributed at equal angles will move towards the suspension plate 4 simultaneously. The distance between adjacent anti-water barriers 5 will decrease or even merge together, and multiple anti-water barriers 5 will form a closed loop (e.g., Figure 3 As shown in the figure, it can act as a barrier to the waves, reducing the impact of the waves on the aquatic plants;

[0063] When the anti-water plate 5 is impacted by water waves and moves towards the suspension plate 4, the fixing cylinder 6 moves on the guide rod 7. The end of the guide rod 7 extending into the fixing cylinder 6 moves further into the fixing cylinder 6, causing the groove 71 to pass through the guide slot and move to the outside of the guide block 63. During this process, the inner wall of the groove 71 is blocked by the inclined surface inside the guide slot. The force of the guide rod 7 moving will drive the guide block 63 downward along the inclined surface inside the guide slot, thus causing the binding hook 64 to move downward. Therefore, the part of the binding hook 64 extending outside the fixing cylinder 6 becomes smaller, the space for binding aquatic plants is reduced, and the aquatic plants can be bound more tightly (e.g., Figure 8 As shown in the figure, this allows for a looser binding of the aquatic plants when the water surface is calm, and a tighter binding when the water surface is turbulent, thus preventing the aquatic plants from being washed away by the waves and not affecting the spawning effect.

[0064] As the anti-aircraft plates 5, which are distributed at equal angles, move towards the suspension plate 4, the anti-aircraft plates 5 will simultaneously drive multiple fixed cylinders 6 to move. The fixed cylinders 6, which are mirrored on both sides, will move towards the middle fixed cylinder 6 due to the limitation of the limiting plate. Therefore, the fixed cylinders 6, which are mirrored on both sides, will cause the aquatic plants to gather on the middle fixed cylinder 6, so that the aquatic plants are in a "clumped" state, thereby preventing the fish eggs on the aquatic plants from being washed away by the waves, and further preventing the aquatic plants from being scattered and falling off.

[0065] It should be noted that the fixed cylinder 6 located in the middle of the anti-resistant plate 5 and the fixed cylinder 6 mirrored on both sides of the fixed cylinder 6 are connected together by a limiting plate. Since the length of the limiting plate remains constant, both ends of the limiting plate are rotatably connected to the fixed cylinder 6 and can slide on the outer wall of the fixed cylinder 6. Therefore, when the three fixed cylinders 6 move towards the suspension plate 4, the two mirrored fixed cylinders 6 will be limited by the limiting plate and their angle will change. The two mirrored fixed cylinders 6 will then move closer to the fixed cylinder 6 in the middle, thereby making the aquatic plants "clump together" to prevent the fish eggs on the aquatic plants from being washed away by the waves.

[0066] When the water surface returns to a calm state or the waves decrease, the anti-impact plate 5 is no longer subjected to a large impact force. Therefore, the first spring 3 is no longer stretched. The first spring 3 can drive the suspension plate 4 to rotate back to its original position. Through the same principle, the multiple fixed cylinders 6 and the anti-impact plate 5 will also return to their initial state. There are small gaps between the multiple anti-impact plates 5. When the water surface waves are not large, the water flow can flow through the gaps to the aquatic plants, increasing the water flow and promoting the proliferation of plankton.

[0067] It should also be noted that the fixing method of anchor bolt 1 and conical anchor can be changed to the method of using a breeding block to connect with ropes to prevent it from drifting away, or to use something like wire for rigid positioning.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
