Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to a water level control device for wetland ecological restoration. Background Art

[0002] Wetlands, unique and vital ecosystems on Earth, are known as the "Kidneys of the Earth." They play an irreplaceable and crucial role in maintaining ecological balance, regulating climate, conserving water resources, purifying water quality, and protecting biodiversity. They not only provide habitats for numerous rare plants and animals but also have a profound impact on regional ecological security and the sustainable development of human society.

[0003] Wetland ecosystems are extremely sensitive to changes in water levels. Appropriate water levels are the basic condition for maintaining the normal operation of wetland ecological functions. Excessively high water levels will cause wetland plants to be submerged for a long time, making it impossible for them to carry out normal photosynthesis and respiration, thereby causing plant death and destroying the wetland vegetation community structure. If the water level is too low, the wetland soil will dry up and the wetland ecosystem will transform into a terrestrial ecosystem. Aquatic organisms that originally relied on the wetland water environment for survival will face a survival crisis and biodiversity will decrease.

[0004] In the existing technology, the water conservancy engineering facilities for regulating water levels include dams, sluices, etc. Although they can regulate water levels to a certain extent, they are usually designed based on single goals such as flood control and irrigation, and it is difficult to accurately meet the complex needs of wetland ecosystems for dynamic changes in water levels. Therefore, people have created water level control devices suitable for wetland ecological environments. However, when traditional water level control devices drain wetlands, the animals and plants living in the wetlands will be discharged together, thereby reducing the biodiversity in the wetlands and causing damage to their internal ecological environment.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During use, the present invention detects the water level in the wetland via an external water level sensor. When the water level exceeds a certain value, the water in the wetland is drained through the first water pump, delivery pipe, suction pipe, and other structures. During this process, the baffles and protective nets block animal cubs and larger plants from being discharged along with the water source. After the water source enters the separation tank, the first and second precision filters block and filter algae in the water source to prevent them from being discharged. After the excess water in the wetland is drained, the first valve, first return pipe, and second valve are used to return the animal cubs in the storage tank to the wetland. At the same time, the first motor, first bevel gear, second return pipe, and other structures cooperate to separate algae on the outer wall of the precision filter and return them to the wetland through the second return pipe. This prevents the animals and plants in the wetland from being discharged during the drainage process, thus protecting them and maintaining the biodiversity and ecological environment of the wetland.

[0018] 2. During use of the present invention, when the water level in the wetland is too low, the second water pump, water pipe and other structures can be used to replenish water in the wetland. In addition, with the cooperation of the second motor, meshing wheel, movable frame, third motor, first gear and other structures, the lifting frame and the multiple steps can be adjusted to appropriate positions to avoid excessive impact of water flow on the biological habitat at the bottom of the wetland when replenishing water in the wetland, thereby protecting the organisms in the wetland and further maintaining the biodiversity within the wetland.

[0019] 3. When the present invention is in use, when draining and replenishing water in the wetland, impurities in the water can be filtered and adsorbed under the action of the filter plate and the filter screen, so as to prevent the impurities in the water source from clogging and damaging the water delivery system of the water level control device, thereby extending the service life of the components in the water delivery system, greatly reducing the maintenance of the water delivery system in the water level control device, and saving cost consumption.

[0029] 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 implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] Example 1, refer to Figures 1-8As shown: The present invention provides a wetland ecological restoration water level control device, including a bottom plate 1, a storage box 2 is fixedly installed on the top of the bottom plate 1, one side of the outer wall of the storage box 2 is fixedly connected with a water suction pipe 3, the inner wall of the water suction pipe 3 is provided with a first valve 4, the outer wall of the water suction pipe 3 is fixedly installed with a protective net 5, one side of the outer wall of the storage box 2 is fixedly connected with a first return pipe 6, the inner wall of the first return pipe 6 is provided with a second valve 7, the inner wall of the storage box 2 is provided with four insertion grooves 8, and a mounting frame 9 is movably inserted between the inner walls of the four insertion grooves 8, the inner wall of the mounting frame 9 is fixedly installed with a baffle 10 by bolts, and the inner wall of the mounting frame 9 is fixedly installed with two filter plates 11 by bolts, one side of the outer wall of the storage box 2 is fixedly connected with a delivery pipe 15, a first water pump 16 is fixedly installed on the top of the bottom plate 1, and the outer wall of the first water pump 16 is fixedly connected to the outer wall of the delivery pipe 15, and a separation box is fixedly installed on the top of the bottom plate 1 17. The outer wall of the separation box 17 is fixedly connected to the outer wall of the delivery pipe 15, and the outer wall of the separation box 17 is fixedly connected to the drain pipe 18. The inner wall of the drain pipe 18 is provided with a third valve 19. The outer wall of the separation box 17 is fixedly connected to the second return pipe 20, and the inner wall of the second return pipe 20 is provided with a fourth valve 21. A top cover 22 is provided on the top of the separation box 17, and a first motor 23 is fixedly installed on the top of the top cover 22. The output end of the first motor 23 is fixedly sleeved with a first bevel gear 24, and a mounting column 25 is movably inserted between the top cover 22 and the inner wall of the separation box 17. The outer wall of the mounting column 25 is fixedly sleeved with a second bevel gear 28, and the outer wall of the second bevel gear 28 is meshed with the outer wall of the first bevel gear 24. The outer wall of the mounting column 25 is fixedly installed with two first precision filter plates 26 by bolts, and the outer wall of the mounting column 25 is fixedly installed with two second precision filter plates 27 by bolts.

[0031] In this embodiment, when the external water level sensor and detection system detects that the water level in the wetland exceeds the set value, the first valve 4 and the third valve 19 are controlled to open and the second valve 7 and the fourth valve 21 are controlled to close under the action of the external controller. Then, under the action of the first water pump 16, the delivery pipe 15 and the suction pipe 3, the water in the wetland is absorbed into the storage tank 2 and enters the separation box 17 through the delivery pipe 15. In this process, under the action of the protective net 5, the larger plants in the wetland can be blocked to avoid blockage of subsequent pipelines, and under the action of the baffle 10, the animal cubs absorbed along with the water source can be blocked to avoid being discharged along with the water source. After the water source is transported to the inside of the separation box 17, the water in the water source can be filtered under the action of the first precision filter plate 26 (made of ceramic membrane) and the second precision filter plate 27 (made of hollow fiber membrane). The algae are blocked and filtered to prevent them from being discharged along with the water source. Then the water source inside the separation box 17 will be discharged through the drain pipe 18. When the excessive water source in the wetland is discharged, the third valve 19 is controlled to be closed, and the second valve 7 and the fourth valve 21 are opened, so that the animal cubs blocked inside the storage box 2 are returned to the wetland from the first return pipe 6. At the same time, under the action of the first motor 23, the first bevel gear 24 and the second bevel gear 28 are driven to rotate, thereby driving the mounting column 25 and the first precision filter plate 26 and the second precision filter plate 27 to rotate rapidly, so that the algae attached to the outer wall of the first precision filter plate 26 and the second precision filter plate 27 fall off and attach to the inner wall of the separation box 17 under the action of centrifugal force. Through the continuous operation of the first water pump 16, the algae inside the separation box 17 will return to the wetland again through the second return pipe 20, thereby completing the drainage treatment of the wetland and greatly maintaining the biodiversity in the wetland ecology.

[0032] Example 2, according to Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 as well as Figure 8As shown, a fixing frame 34 is fixedly installed on the top of the bottom plate 1, and a plurality of meshing grooves 35 are opened on the top of the fixing frame 34. Two slide grooves 36 are opened on the top of the fixing frame 34, and a movable frame 37 is movably embedded between the inner surface walls of the two slide grooves 36. A second motor 38 is fixedly installed on the top of the movable frame 37, and a meshing wheel 39 is fixedly sleeved on the output end of the second motor 38. A fixing groove 40 is opened on the top of the movable frame 37, and a transmission wheel 41 is movably inserted into the inner surface wall of the fixing groove 40. The outer wall of the transmission wheel 41 is meshed with the outer wall of the meshing wheel 39, and the outer wall of the transmission wheel 41 is meshed with the outer wall of the meshing groove 35. A third motor 42 is fixedly installed on one side of the outer wall of the movable frame 37, and the output of the third motor 42 is fixedly sleeved. A first gear 43 is fixedly sleeved at the end, a lifting frame 46 is movably embedded between the inner surface walls of the movable frame 37, a lead screw 44 is movably inserted into the inner surface wall of the movable frame 37, and the outer surface wall of the lead screw 44 is connected to the inner surface wall of the lifting frame 46 by a threaded connection, a second gear 45 is fixedly sleeved on the outer surface wall of the lead screw 44, and the outer surface wall of the second gear 45 is meshed with the outer surface wall of the first gear 43, the inner surface wall of the lifting frame 46 is fixedly installed with a multi-step step 47, the inner surface wall of the multi-step step 47 is fixedly inserted with a plurality of water outlet pipes 48, a guide plate 49 is fixedly installed on one side of the outer wall of the multi-step step 47, a second water pump 33 is fixedly installed on the top of the bottom plate 1, and the outer surface wall of the second water pump 33 is fixedly connected to the outer surface wall of the water pipe 32.

[0033] In this embodiment, when the water level in the wetland is detected to be lower than the set value by the external water level sensor and detection system, the wetland needs to be replenished with water. Under the action of the second motor 38, the meshing wheel 39 is driven to rotate. At the same time, with the cooperation of the transmission wheel 41 and the meshing groove 35, the movable frame 37 can be driven to move to a suitable position inside the slide groove 36. Then, under the action of the third motor 42, the first gear 43 is driven to rotate. At the same time, under the action of the second gear 45, the lead screw 44 can be driven to rotate, thereby driving the lifting frame 46 and the multi-step steps 47 to move downward, so that the bottom of the multi-step steps 47 contacts the water surface of the wetland. Subsequently, under the action of the second water pump 33, the water pipe 32 and the outlet pipe 48, the wetland can be replenished with water. When the water source passes through the guide plate 49, the water flow can be dispersed into multiple slow streams, so that it slowly enters the wetland, thereby protecting the biological habitat at the bottom of the wetland.

[0034] Example 3, according to Figure 1 、 Figure 2 、 Figure 4 as well as Figure 8As shown, two mounting grooves 12 are provided on the top of the mounting frame 9, and the inner surface walls of the two mounting grooves 12 are movably embedded with a limit shaft 13, and one side of the inner wall of the two mounting grooves 12 is fixedly installed with a limit spring 14, and one side of the outer wall of the limit spring 14 is fixedly connected to one side of the outer wall of the limit shaft 13, and a filter box 29 is fixedly installed on the top of the base plate 1, and one side of the outer wall of the filter box 29 is fixedly connected to the water inlet pipe 30, and a plurality of filter screens 31 are movably inserted into the inner surface wall of the filter box 29, and one side of the outer surface of the filter box 29 is fixedly connected to the water pipe 32, and the outer wall of the water pipe 32 is fixedly connected to the outer wall of the water outlet pipe 48.

[0035] In this embodiment, when draining and replenishing water in the wetland, the filter plate 11 and the filter screen 31 can filter and block impurities in the wetland, preventing impurities in the wetland from moving with the water source and accumulating inside the subsequent pipeline to cause pipeline blockage, thereby greatly improving the water delivery effect. After the water delivery is completed, the staff can press the limit shaft 13 to make it move inside the mounting groove 12 and compress the limit spring 14, so that the limit shaft 13 no longer limits the mounting frame 9 and the storage box 2, thereby disassembling the mounting frame 9, making it easier for the staff to maintain and replace the baffle 10 and the filter plate 11. After the maintenance and replacement are completed, the mounting frame 9 is installed and fixed under the action of the limit spring 14 and the limit shaft 13, which greatly improves the maintenance and replacement efficiency of the baffle 10 and the filter plate 11.

[0036] The working principle of the entire mechanism is as follows: when repairing the wetland ecology, the water level in the wetland is first detected by an external water level sensor and detection system. When the water level in the wetland is higher than the set value, the first valve 4 and the third valve 19 are controlled to open and the second valve 7 and the fourth valve 21 are controlled to close under the action of the external controller. Subsequently, under the action of the first water pump 16, the delivery pipe 15 and the suction pipe 3, the water in the wetland is absorbed into the storage tank 2 and enters the separation tank 17 through the delivery pipe 15. In this process, the protective net 5 can block the larger plants in the wetland to avoid blockage of subsequent pipelines, and the baffle 10 can block the water that follows the water source. The absorbed animal cubs play a blocking role to prevent them from being discharged along with the water source. Under the action of the filter plate 11, impurities in the water source can be adsorbed and filtered to avoid clogging of subsequent pipelines. After the water source is transported to the inside of the separation box 17, the algae in the water source can be blocked and filtered under the action of the first precision filter plate 26 (made of ceramic membrane) and the second precision filter plate 27 (made of hollow fiber membrane) to prevent them from being discharged along with the water source. Then the water source inside the separation box 17 will be discharged through the drain pipe 18. When the excess water in the wetland is discharged, the third valve 19 is controlled to close, and the second valve 7 and the fourth valve 21 are opened to allow the animal cubs blocked inside the storage box 2 to return to the wetland from the first return pipe 6. At the same time, under the action of the first motor 23, the first bevel gear 24 and the second bevel gear 28 are driven to rotate, thereby driving the mounting column 25 and the first precision filter plate 26 and the second precision filter plate 27 to rotate rapidly, so that the algae attached to the outer wall of the first precision filter plate 26 and the second precision filter plate 27 fall off and adhere to the inner wall of the separation box 17 under the action of centrifugal force. Through the continuous operation of the first water pump 16, the algae inside the separation box 17 will pass through the second return pipe 20 and return to the wetland again, thereby completing the drainage treatment of the wetland. When it is detected that the water level in the wetland is lower than the set value, it is necessary to replenish water in the wetland. Under the action of the second motor 38, the meshing wheel 39 is driven to rotate. At the same time, with the cooperation of the transmission wheel 41 and the meshing groove 35 Under the action of the third motor 42, the movable frame 37 can be driven to move to the appropriate position inside the slide 36, and then the first gear 43 can be driven to rotate under the action of the second motor 42. At the same time, the screw 44 can be driven to rotate under the action of the second gear 45, thereby driving the lifting frame 46 and the multi-step steps 47 to move downward, so that the bottom of the multi-step steps 47 contacts the water surface of the wetland. Subsequently, under the action of the second water pump 33, the water pipe 32, the water inlet pipe 30 and the water outlet pipe 48, the wetland can be replenished with water. When the water source passes through the guide plate 49, the water flow can be dispersed into multiple slow flows, so that it slowly enters the wetland, avoiding excessive impact of the water flow on the biological habitat at the bottom of the wetland and causing scouring and damage. After the water delivery is completed, under the operation of the staff,Pressing the limit shaft 13 causes it to move inside the mounting groove 12 and compresses the limit spring 14, so that the limit shaft 13 no longer limits the mounting frame 9 and the storage box 2, thereby removing the mounting frame 9, making it easier for the staff to maintain and replace the baffle 10 and the filter plate 11. After the maintenance and replacement are completed, the mounting frame 9 is installed and fixed under the action of the limit spring 14 and the limit shaft 13, which greatly improves the maintenance and replacement efficiency of the baffle 10 and the filter plate 11.

[0037] The pipes inside the device are all rubber hoses with good deformation ability.
