[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. However, while water conservancy project construction brings many benefits such as flood control, power generation, and water supply, it also changes the natural ecosystem of rivers, lakes and other water bodies. For example, the construction of dams will block the migration channels of fish, making it impossible for many migratory fish to reach their spawning grounds, resulting in a decline in their population.

[0003] Ecological floating bed is a commonly used ecological environment management device for water conservancy projects. Ecological floating bed is based on aquatic plants, using the principle of soilless cultivation technology, using polymer materials as carriers and substrates, applying the symbiotic relationship between species, and making full use of the spatial niche and nutritional niche of the water body, so as to establish an efficient artificial ecosystem to reduce the pollution load in the water body.

[0004] In the related art, for example, a Chinese patent with patent announcement number CN222250285U proposes a structurally stable floating bed for water ecological restoration, comprising a float, a planting pot placed inside the float, a stabilizing component arranged between four adjacent floats, a reinforcing component arranged on the upper surface of the outermost circle of the float, the stabilizing component comprising a reinforcing ring installed on the upper surface of the four floats, a clamping plate contacting the upper end of the planting pot arranged on the upper surface of the reinforcing ring, a mounting hole opened on the surface of the float, the reinforcing component comprising two lower reinforcing plates and an upper reinforcing plate connected end to end, the connecting ends of the upper reinforcing plate and the lower reinforcing plate being detachably connected by a guide rod and a mounting ring; the utility model utilizes the stabilizing component to prevent the planting pot inside the float from falling off and stabilize it, and at the same time, to reinforce the adjacent spliced ​​floats, thereby increasing the splicing stability, and utilizing the reinforcing component to reinforce the edge structure of the floating bed, thereby increasing the use strength and stability of the entire floating bed.

[0005] The above-mentioned related technologies have the following defects: when the wind is strong, the water ecological restoration floating bed is prone to overturning during use, thereby affecting the normal use of the water ecological restoration floating bed. Summary of the invention

[0006] In order to prevent the ecological floating bed from overturning and affecting its normal use, the present application provides an ecological environment management device for a water conservancy project.

[0007] The present application provides a water conservancy project ecological environment governance device that adopts the following technical solution: A water conservancy project ecological environment governance device, comprising: floating bed body; A fixing assembly is used to fix the floating bed body, and the fixing assembly includes: Counterweight block, multiple blocks are provided; A fixing rope, wherein a plurality of fixing ropes are provided, and the fixing ropes correspond to the counterweight blocks one by one. A rotating rod is rotatably connected to the floating bed body, and one end of each of the fixing ropes is connected to the corresponding counterweight block, and the other end is connected to the rotating rod; The floating bed body is provided with a rotating assembly for driving the rotating rod to rotate.

[0008] By adopting the above technical solution, when the wind is strong, the rotating assembly runs and drives the rotating rod to rotate. The rotating rod reels in the fixed rope so that the floating bed body moves toward the bottom of the water under the action of the counterweight block, that is, the center of gravity of the floating bed body moves downward, so that the floating bed body is not easy to overturn and affect the normal use of the ecological floating bed.

[0009] Furthermore, the fixing assembly further comprises: A fixing rod, one end of which is detachably connected to the floating bed body and the other end of which extends toward the bottom of the water; A plurality of connecting rods are provided, and the plurality of connecting rods are arranged along the circumference of the fixed rod, and one end of the connecting rod is rotatably connected to the fixed rod, and the other end of the connecting rod can be rotated toward or away from the water bottom; A buoyancy cloth connected to the connecting rod; The connecting rod is arranged one by one with the connecting rod, and one end of the connecting rod is slidingly hinged with the fixed rod, and the other end is rotatably connected with the buoyancy cloth; The fixed rod is provided with a driving assembly for driving the connecting rod to slide.

[0010] By adopting the above technical solution, when the ecological floating island is put in place, the driving assembly is controlled to make the connecting rod slide, and the connecting rod pushes the buoyancy cloth to unfold, thereby further making the ecological floating island less likely to capsize.

[0011] Furthermore, the driving assembly comprises: The driving ring and the sliding sleeve are arranged outside the fixed rod and are rotatably connected with the connecting rod; The driving block is fixedly connected to the driving ring.

[0012] By adopting the above technical solution, when the ecological floating island is placed in place, the driving block drives the connecting rod to move under the action of its own gravity, so that the connecting rod drives the buoyancy cloth to move to realize the spreading of the buoyancy cloth.

[0013] Furthermore, the driving assembly also includes a driving rope, one end of which is connected to the driving ring, and the other end of which is connected to the floating bed body.

[0014] By adopting the above technical solution and the provision of the driving rope, it is convenient for the staff to control the driving rope to realize the folding of the buoyancy cloth, that is, it is convenient for the staff to retract the ecological floating island.

[0015] Furthermore, the rotating assembly comprises: The support rod is fixedly connected to the floating bed body, and the fixing rod is sleeved on the outside of the support rod and is rotatably connected to the support rod; A rotating rod is rotatably connected to the supporting rod, and the setting direction of the rotating rod is perpendicular to the length direction of the supporting rod; A plurality of rotating blades are provided, and the plurality of rotating blades are arranged along the circumference of the rotating rod and are fixedly connected to the rotating rod; A rotating bevel gear, coaxially and fixedly connected to the rotating rod; The transmission bevel gear is coaxially fixedly connected with the rotating rod and meshes with the rotating bevel gear.

[0017] Furthermore, a connecting edge is fixedly connected to the peripheral side of the floating bed body, and the connecting edge extends away from a side of the floating bed body toward the direction close to the water bottom.

[0018] By adopting the above technical solution, the connection edge is set so that after the floating bed body is put into the water, the connection edge is submerged below the water surface, thereby further making the ecological floating bed less likely to overturn.

[0019] Furthermore, the floating bed body comprises: A floating bed frame connected to the fixed assembly; The planting pot is detachably connected to the floating bed frame through a connecting assembly, and the connecting assembly includes: A connecting block is provided on the floating bed frame, wherein the connecting groove is L-shaped, and a side of the connecting groove facing away from the bottom of the water is set as an opening, and the connecting block is snap-fitted with the connecting groove.

[0020] By adopting the above technical solution, the staff can connect the planting pot and the floating bed frame after inserting the connecting block into the connecting groove.

[0021] Furthermore, the connection component also includes: The connecting plate is rotatably connected to the connecting block. A connecting torsion spring is provided on the connecting block, and one end of the connecting torsion spring is connected to the connecting block, and the other end is connected to the connecting plate. Under the elastic force of the connecting torsion spring, the connecting plate can contact the side of the connecting groove away from the bottom of the water.

[0022] By adopting the above technical solution, the setting of the connecting plate makes it less likely for the connecting block to be detached from the connecting groove after the staff puts the ecological floating island into the water.

[0024] By adopting the above technical scheme, when the wind force is strong, when the fixed rope drives the floating bed body to move toward the bottom of the water, the gas pressure in the cavity of the floating bed body increases, thereby further driving the pushing block to rotate the connecting plate, thereby making the connecting plate and the side wall of the connecting groove away from the accommodating groove more tightly contacted, that is, the connection between the planting pot and the floating bed frame is tighter; as the wind force increases or the floating bed body moves toward the bottom of the water due to the growth of plants on the floating bed body, it becomes more tightly connected, thereby making it less likely for the clamping block and the connecting ring to loosen, thereby improving the stability of the connection between the clamping block and the connecting ring.

[0025] To sum up, the beneficial technical effects of the present application are as follows: when the wind is strong, the rotating assembly runs and drives the rotating rod to rotate, and the rotating rod reels in the fixed rope so that the floating bed body moves toward the bottom of the water under the action of the counterweight block, that is, the center of gravity of the floating bed body moves downward, so that the floating bed body is not easy to overturn and affect the normal use of the ecological floating bed.

A plurality of receiving grooves 143 are provided on the floating bed body 100. The receiving grooves 143 are annular in cross section, and the size of the receiving grooves 143 gradually decreases as they approach the bottom of the water. The planting pot 150 is mounted in the receiving groove 143. The planting pot 150 is detachably connected to the side wall of the receiving groove 143 through a connection assembly 500.

[0036] There are multiple groups of connection components 500, and the multiple groups of connection components 500 are evenly arranged along the circumference of the planting pot 150. In this embodiment, the connection components 500 are specifically configured as follows: the connection components 500 include a connection block 510 and a connection plate 520, and the connection block 510 is fixedly connected to the side wall of the planting pot 150. A connection groove 1431 is provided on the side wall of the accommodating groove 143, and the connection groove 1431 is L-shaped, and the side of the connection groove 1431 away from the bottom of the water is set as an opening, so that when the staff puts the planting pot 150 into the accommodating groove 143, the connection block 510 is inserted from the opening of the connection groove 1431, and then the planting pot 150 is rotated until the connection block 510 conflicts with the bottom of the connection groove 1431.

[0037] In order to improve the stability of the connection block 510 and the connection groove 1431, a receiving groove 1432 is provided on the side of the connection groove 1431 close to the bottom of the water, and the connection block 510 and the receiving groove 1432 can be engaged.

[0038] In order to further improve the connection stability between the connection block 510 and the connection groove 1431 and the receiving groove 143, a plurality of cavities 160 are provided on the side of the floating bed body 100 close to the bottom of the water. The plurality of cavities 160 are arranged corresponding to the receiving groove 143, and the cavities 160 are arranged around the corresponding receiving groove 143. The side wall of the receiving groove 143 is connected with a sliding hole 1433, and the side of the sliding hole 1433 away from the receiving groove 143 is connected with the corresponding cavity 160. A push block 1434 is arranged in the sliding hole 1433, and the push block 1434 is sealed and slidably connected with the side wall of the sliding hole 1433. The side of the push block 1434 close to the planting pot 150 can contact the connection plate 520, so that the push block 1434 can push the connection plate 520 to rotate until the free end of the connection plate 520 contacts the side wall of the connection groove 1431 away from the receiving groove 143.

[0039] When the staff puts the planting pot 150 into the accommodating groove 143, the connecting block 510 is inserted into the connecting groove 1431 from the connecting groove 1431, and then the planting pot 150 is rotated until the connecting block 510 is aligned with the accommodating groove 1432, and then the planting pot 150 is released, so that the planting pot 150 can drive the connecting block 510 to enter the accommodating groove 1432, and at this time, the connecting plate 520 is turned into the connecting groove 1431 under the action of the connecting torsion spring; when the floating bed body 100 moves toward the bottom of the water, the pressure in the cavity 160 increases, and pushes the pushing block 1434 to move into the connecting groove 1431, so that the pushing block 1434 pushes the connecting plate 520 so that the connecting plate 520 drives the connecting block 510 to contact the bottom of the accommodating groove 1432, thereby improving the connection stability between the planting pot 150 and the floating bed frame 140.

[0040] The fixing assembly 200 includes a counterweight 210, a fixing rope 220, a fixing rod 230, a connecting rod 240, a buoyancy cloth 250 and a connecting rod 260. The floating bed body 100 is rotatably connected to a rotating rod 110, and a wire roller 120 is coaxially fixedly connected to the rotating rod 110. Multiple fixing ropes 220 and counterweights 210 are provided. In this embodiment, four fixing ropes 220 are provided, and four counterweights 210 are provided. The fixing ropes 220 and the counterweights 210 are provided one by one, and one end of the fixing rope 220 is fixedly connected to the wire roller 120, and the other end is fixedly connected to the counterweight 210.

[0041] In order to allow the fixing rope 220 to be smoothly wound around the line roller 120, a plurality of positioning rods 142 are rotatably connected to the floating bed frame 140. The plurality of positioning rods 142 are grouped in pairs, and a group of positioning rods 142 corresponds to one fixing rope 220. The two positioning rods 142 in the same group are arranged on both sides of the fixing rope 220, so that when the line roller 120 rotates, the fixing rope 220 is wound around the line roller 120 under the action of the positioning rods 142.

[0042] The floating bed body 100 is provided with a rotating assembly 300 for driving the rotating rod 110 to rotate, and the rotating assembly 300 includes a support rod 310, a rotating rod 320, a rotating blade 330, a rotating bevel gear 340 and a transmission bevel gear 350. The support rod 310 is fixedly connected to the floating bed body 100, and the rotating rod 110 is rotatably sleeved on the support rod 310. The rotating rod 320 is rotatably connected to the support rod 310, and the length direction of the rotating rod 320 is perpendicular to the length direction of the support rod 310. A plurality of rotating blades 330 are provided, and the plurality of rotating blades 330 are evenly arranged along the circumference of the rotating rod 320, and the rotating blades 330 are fixedly connected to the rotating rod 320 at one end, and the other end extends in a direction away from the rotating rod 320. The rotating bevel gear 340 is coaxially fixedly connected to the rotating rod 320, and the transmission bevel gear 350 is coaxially fixedly connected to the rotating rod 110 and meshes with the rotating bevel gear 340.

[0043] In order to make the service life of the rotating component 300 less susceptible to the influence of rain and the like, a shell 311 is fixedly connected to the support rod 310. The shell 311 is rectangular and is sleeved on the outside of the rotating bevel gear 340 and the transmission bevel gear 350. The rotating rod 320 is rotatably connected to the support rod 310, and the other end passes through the shell 311 and is connected to the rotating blade 330.

[0044] When the wind is strong, the rotating blades 330 rotate under the action of the wind, thereby driving the rotating rod 320 to rotate, that is, the rotating bevel gear 340 rotates. Since the rotating bevel gear 340 and the transmission bevel gear 350 are meshed, the transmission bevel gear 350 rotates and drives the rotating rod 110 to rotate, thereby driving the line roller 120 to rotate and making the fixing rope 220 wound around the line roller 120, so that the ecological floating bed is tightened and the ecological floating bed is not easy to overturn.

[0045] In order to distribute the tension on the fixing rope 220 on the floating bed frame 140 when the fixing rope 220 is tensioned, a plurality of rotating rollers 130 are rotatably connected to the floating bed frame 140. The plurality of rotating rollers 130 are divided into four groups. The four groups of rotating rollers 130 correspond one-to-one to the fixing rope 220, and the fixing rope 220 can contact the rotating rollers 130.

[0046] In order to further prevent the ecological floating bed from capsizing, one end of the fixed rod 230 is detachably connected to the floating bed frame 140, and the other end extends toward the bottom of the water. A plurality of connecting rods 240 are provided, and the plurality of connecting rods 240 are arranged circumferentially along the fixed rod 230, and one end of the connecting rod 240 is rotatably connected to the side of the fixed rod 230 away from the floating bed body 100, and the other end rotates toward or away from the bottom of the water. In order to limit the rotation angle of the connecting rod 240, one end of the fixed rod 230 away from the floating bed frame 140 is fixedly connected to the limiting plate 233, so that when the connecting rod 240 rotates to contact the side of the limiting plate 233 away from the bottom of the water, the connecting rod 240 is not easy to continue to rotate. The buoyancy cloth 250 is arranged in an annular shape, and a hole for the connecting rod 240 to pass through is arranged on the buoyancy cloth 250. The connecting rod 260 is arranged in a one-to-one correspondence with the connecting rod 240, and one end of the connecting rod 260 is slidably hinged with the fixing rod 230, and the other end is rotatably connected with the buoyancy cloth 250. The fixing rod 230 is provided with a driving assembly 400 for driving the connecting rod 260 to slide.

[0047] The driving assembly 400 includes a driving ring 410, a driving rope 420 and a driving block 430. The driving ring 410 is slidably sleeved on the outside of the fixing rod 230 and is rotatably connected to the end of the connecting rod 260 away from the connecting rod 240. The driving block 430 is fixedly connected to the driving ring 410, and one end of the driving rope 420 is connected to the driving block 430, and the other end extends beyond the floating bed body 100 and is fixedly connected to the fixing rod 230.

[0048] In order to reduce the resistance encountered by the staff when retracting the buoyancy cloth 250, an elastic rope is provided on the connecting rod 240, one end of the elastic rope is connected to the end of the connecting rod 240 close to the fixed rod 230, and the other end is connected to the side of the buoyancy cloth 250 away from the fixed rod 230. Under the action of the elastic rope, the buoyancy cloth 250 is retracted, so that when the staff pulls the driving rope 420 to move the driving block 430 and the driving ring 410 away from the bottom of the water, the elastic rope can retract the buoyancy cloth 250, thereby reducing the resistance encountered by the staff when retracting the connecting rod 260 and the connecting rod 240.

[0049] In this embodiment, the detachable connection between the fixing rod 230 and the floating bed body 100 is specifically configured as follows: a connecting hole for the fixing rod 230 to pass through is opened on the floating bed body 100, a fixing plate 231 is fixedly connected to the fixing rod 230, the fixing plate 231 is located on the side of the floating bed body 100 close to the bottom of the water, a fixing ring 232 is threadedly connected to the fixing rod 230, the fixing ring 232 is located on the side of the floating bed body 100 away from the bottom of the water, and is in conflict with the floating bed body 100.

[0050] The implementation principle of the ecological environment management device of a water conservancy project in an embodiment of the present application is: when the wind force is strong, the rotating blades 330 rotate under the action of the wind, thereby driving the rotating rod 320 to rotate, that is, the rotating bevel gear 340 rotates. Since the rotating bevel gear 340 and the transmission bevel gear 350 are meshed, the transmission bevel gear 350 rotates and drives the rotating rod 110 to rotate, thereby driving the line roller 120 to rotate and causing the fixed rope 220 to be wound around the line roller 120, so that the ecological floating bed is not prone to overturning.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
