Description

Technical Field

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

[0002] As the "kidneys" of the earth, wetlands undertake important ecological service functions such as filtering pollutants, regulating runoff, and providing habitats. However, due to the impact of human activities, wetlands are facing serious degradation and pollution problems. Ecological floating islands, as a green and low-cost restoration technology, are widely used in the ecological restoration of wetland water bodies.

[0003] Traditional ecological floating islands are equipped with aeration devices to suck deep water and spray it on the water surface. On the one hand, this increases the oxygen content of the water, and on the other hand, it facilitates the absorption and utilization of bottom sewage by surface aquatic plants. When taking water from the water body, water can only be taken from a single water layer, and the distribution of pollutants in the water body is usually uneven. Water layers at different depths contain different types of pollutants and different degrees of pollution. Taking water from a single water layer means that these pollutants cannot be fully exposed, which limits the efficiency and effectiveness of the restoration device. There may be stratification caused by temperature or density differences in the water body. Taking water from a single water layer cannot promote the mixing of the water body, which may cause the upper layer to be oxygen-rich and the lower layer to be oxygen-deficient, which is not conducive to the natural circulation and ecological balance of the water body.

[0004] And with the change of water level, when the water level is shallow, the water inlet is easy to touch the bottom and absorb the silt at the bottom of the riverbed. The silt and sediment are easy to block the water inlet and the filter device, affecting the normal operation of the aeration device, increasing the maintenance frequency and cost. The stirring of the bottom mud may destroy the habitat of the benthic organisms, cause harm to the benthic organisms, and affect the structure and function of the wetland ecosystem. Therefore, a wetland water ecological restoration device is needed to solve the above problems. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The buoyancy regulating mechanism of the present invention adjusts the overall buoyancy by changing the gas volume in the buoyancy cylinder, so that the device can float up and down in the water body. This design enables the device to access water bodies at different depths, thereby repairing both deep and surface water bodies. Since pollutants in water bodies are often unevenly distributed, by taking water at different depths, the equipment helps to break the water stratification and promote the mixing of upper and lower water bodies, which is conducive to the balanced distribution of nutrients and dissolved oxygen, improves the overall ecological environment of the water body, and greatly improves the repair effect and efficiency of the water body.

[0023] 2. The present invention generates water flow through rotation through the disturbance mechanism, thereby promoting the circulation of water in the horizontal direction. The flow of water caused by the disturbance helps pollutants to fully contact with microorganisms and accelerates the biodegradation process. The water flow disturbance promotes the circulation of the surrounding water and helps to bring the oxygen-rich water on the surface to the deeper layer, and vice versa. During the disturbance process, the disturbance mechanism will stir the culture fiber balls filled with nitrifying bacteria. These bacteria are sent into the surrounding waters along with the water flow. The wide distribution and activity of nitrifying bacteria help to significantly reduce the ammonia nitrogen content in the water, further improving the equipment's efficiency in repairing the water.

[0024] 3. The present invention ensures the stability of the device by balancing the buoyancy provided by the float with the gravity of the counterweight cylinder. Even in the case of turbulent water flow or strong winds and waves, the device can maintain a vertical posture, so that when the component sinks to the bottom, the filter cartridge maintains a certain distance from the riverbed, avoiding direct contact with the riverbed sediment, reducing water inlet resistance, and also protecting the filter cartridge from damage. Since the filter cartridge maintains a certain distance from the riverbed, the accumulation of sediment and impurities is reduced, daily maintenance and cleaning work are simplified, and operating costs are reduced. The detachable design allows each component to be easily disassembled for inspection and cleaning when necessary, or quickly replaced when damaged, thereby improving the service life of the equipment and the convenience of maintenance.

[0037] See also Figure 1-Figure 11 A wetland water ecological restoration device includes a floating island body 1, a green plant planting box 2 and an aeration mechanism 3. The lower end of the aeration mechanism 3 is provided with a floating water intake component 4 matched therewith. The floating water intake component 4 includes a buoyancy adjustment mechanism 401, a filter cartridge 402, a weight cartridge 403, and a flow disturbance mechanism 404.

[0038] A buoyancy ring 101 is provided at the bottom of the floating island body 1, a solar photovoltaic panel 102 is provided inside the side of the floating island body 1, and an energy storage battery 103 cooperating with the solar photovoltaic panel 102 is provided inside the floating island body 1;

[0039] The aeration mechanism 3 includes a water inlet pipe 301, a water pump 302, a drainage pipe 303 and a rotating nozzle 304. The aeration mechanism 3 is installed on the upper end surface of the floating island body 1;

[0040] The buoyancy adjustment mechanism 401 includes a buoyancy cylinder 4011, an adjustment piston 4015, a motor 4012, a first reducer 4013, a cam 4014 and a spring 4016. The buoyancy adjustment mechanism 401 is installed at the upper end of the filter cylinder 402;

[0041] The top of the filter cartridge 402 is connected to the water inlet pipe 301, and the weight cartridge 403 is detachably mounted on the bottom of the filter cartridge 402. The top of the weight cartridge 403 is provided with an external thread, and the top and bottom of the filter cartridge 402 are provided with internal threads. The weight cartridge 403 is connected to the filter cartridge 402 through threads, and the bottom of the buoyancy cartridge 4011 is provided with an external thread. The filter cartridge 402 and the buoyancy cartridge are connected through threads, which facilitates the independent disassembly, maintenance and replacement of each accessory.

[0042] The flow-disturbing mechanism 404 includes an impeller 4041 , a propeller 4043 and a second reducer 4042 . The flow-disturbing mechanism 404 is installed in the counterweight cylinder 403 and the filter cylinder 402 .

[0043] Furthermore, a through hole 40114 is provided at the center of the buoyancy cylinder 4011, a docking tube 4021 is provided at the top of the filter cylinder 402, the water inlet pipe 301 passes through the through hole 40114 and is fixedly installed on the docking tube 4021, the top of the counterweight cylinder 403 is a hollow structure, a counterweight block 4033 is provided at the bottom of the counterweight cylinder 403, and a first filter hole 4022 is provided on the side wall of the filter cylinder 402.

[0044] The entire floating water intake structure is a long cylindrical structure with a light top and a heavy bottom, so that it can always remain vertical, and the hollow counterweight cylinder 403 structure, when the floating water intake structure sinks to the bottom, the filter cylinder 402 and the bottom riverbed always maintain a distance of the length of the counterweight cylinder 403, to prevent the filter cylinder 402 from being affected by the mud at the bottom of the riverbed and causing excessive water inlet resistance.

[0045] Furthermore, the buoyancy cylinder 4011 includes a main air chamber 40111 and a secondary air chamber 40112. The top of the main air chamber 40111 and the top of the secondary air chamber 40112 are provided with through-connected air holes 40113. The secondary air chamber 40112 is located on the left and right sides of the main air chamber 40111. The bottom of the secondary air chamber 40112 is an open structure. The adjusting piston 4015 is installed in the secondary air chamber 40112 and is slidably and sealedly connected to the buoyancy cylinder 4011.

[0046] By changing the height of the adjusting piston 4015, the gas on the top of the piston 4015 is pressed into the main air chamber 40111, thereby changing the displacement volume of the buoyancy cylinder 4011 and changing the buoyancy of the buoyancy cylinder 4011. When the buoyancy of the buoyancy cylinder 4011 is greater than the overall gravity of the floating water intake assembly 4, the buoyancy cylinder 4011 drives the filter cylinder 402 to float up. When the buoyancy of the buoyancy cylinder 4011 is less than the overall gravity of the floating water intake assembly 4, the buoyancy cylinder 4011 drives the filter cylinder 402 to sink.

[0047] Furthermore, the motor 4012 is installed in the main air chamber 40111, and the cam 4014 is installed in the auxiliary air chamber 40112. The motor 4012 and the cam 4014 are connected by transmission through the first reducer 4013. The cam 4014 is connected to the upper end surface of the piston 4015 in sliding contact. The spring 4016 is installed at the bottom of the adjusting piston 4015. The adjusting piston 4015 is elastically slidably connected to the buoyancy cylinder 4011 through the spring 4016.

[0048] The motor 4012 and the reducer cooperate to drive the cam 4014 to rotate slowly, so that the regulating piston 4015 slowly and intermittently slides up and down under the cooperation of the cam 4014 and the spring 4016, so that the buoy intermittently floats up or sinks, and water is taken in and aerated at different depths of water, thereby increasing the repair range and improving the repair efficiency.

[0049] Furthermore, the cam 4014 includes a first annular segment 40141 , a connecting segment 40143 and a second annular segment 40142 , the diameter of the second annular segment 40142 is larger than the diameter of the first annular segment 40141 , and a rotatably connected roller 4017 is disposed on the top of the regulating piston 4015 .

[0050] When the second annular segment 40142 contacts the roller 4017, the displacement volume of the float is at its maximum state, and the buoyancy cylinder 4011 drives the floating water intake component 4 to float up. When the roller 4017 slides to the first annular segment 40141 through the connecting segment 40143, the buoyancy displacement volume gradually decreases. When it reaches the first annular segment 40141, the displacement volume is at its minimum state. At this time, the buoyancy is not enough to support the gravity of the floating water intake component 4, causing it to sink under the action of its own gravity, thereby causing the floating water intake component 4 to reciprocate up and down with the cooperation of the motor 4012 and the cam 4013.

[0051] Furthermore, the impeller 4041 is installed inside the butt joint 4021, the impeller 4041 is fixedly installed on the input shaft of the second reducer 4042, the propeller 4043 is installed on the two output shafts of the second reducer 4042, and the second reducer 4042 is driven by three sets of meshing gear bevels.

[0052] When the water pump 302 pumps water, the water flows through the butt joint 4021, driving the impeller 4041 to rotate at high speed, thereby driving the propeller 4043 to rotate through the second reducer 4042, and the propeller 4043 discharges water to the side, driving the water flow around the counterweight cylinder 403 to flow.

[0053] Furthermore, drainage ports 4031 are provided on the front and rear sides of the counterweight cylinder 403 , second filtering holes 4032 are provided on the left and right sides of the counterweight cylinder 403 , and the propeller 4043 is installed in the drainage ports 4031 .

[0054] The two groups of propellers 4043 have drainage ports 4031 for discharging water outward, thereby sucking surrounding water into the counterweight cylinder 403 through the second filter holes 4032 , so that the surrounding water circulates inside and outside the counterweight cylinder 403 .

[0055] Furthermore, the interior of the weight cylinder 403 is filled with bacterial culture fiber balls 4034 .

[0056] There are a large number of nitrifying bacteria on the surface of the culture fiber ball 4034. When the disturbance mechanism 404 drives the surrounding water flow to circulate in the counterweight cylinder 403, the water flow will carry away a large number of nitrifying bacteria. The nitrifying bacteria can reduce the concentration of ammonia nitrogen in the water body, which is beneficial to maintaining the health of the aquatic ecosystem and promoting the growth of beneficial microorganisms and other aquatic organisms.

[0057] Furthermore, the bottom of the counterweight cylinder 403 is a spherical top structure, and the surface of the counterweight cylinder 403 is sprayed with an anti-corrosion coating.

[0058] The spherical top structure enables the floating water intake assembly 4 to adapt to different riverbed environments and to stand stably on the surfaces of gravel and soil. The anti-corrosion coating can effectively increase the service life of the counterweight tube 403.

[0059] Furthermore, the water inlet pipe 301 is made of a cross-linked polyethylene pipe.

[0060] Cross-linked polyethylene pipes are extremely soft and easy to install. They maintain good flexibility even under low temperature conditions and have excellent anti-aging and corrosion resistance, which can greatly extend the service life of the equipment.

[0061] When the device is used, a proper amount of aquatic plants are planted in the green plant planting box 2, the floating island body 1 is placed in the selected water area, ensuring that it is stable and facing the sun correctly to maximize the collection of solar energy to power the water pump 302 and the motor 4012, and a proper amount of bacterial fiber balls 4034 are filled in the counterweight cylinder 403. The floating water intake component 4 is placed in the water body, and the water pump 302 is started. The water pump 302 pumps water through the floating water intake component 4, and the rotating nozzle 304 sprays water to increase the dissolved At the same time, the motor 4012 is started, and the motor 4012 drives the cam 4014 to rotate, and begins to adjust the drainage volume of the buoyancy tube 4011, so that the floating water intake component 4 floats up and down, and sprinkles water in different water layers to increase the water body repair range. At the same time, the water flow drives the impeller 4041 to rotate, and drives the stirring paddle to rotate through the second reducer 4042, so that the disturbance mechanism 404 circulates and sucks the surrounding water body, increases the contact area between the water body and the bacterial culture fiber ball 4034, and improves the bacterial culture effect.

[0062] The buoyancy regulating mechanism 401 enables the device to automatically float up and down between different water depths. This feature allows the device to take in water and aerate in the vertical direction, thereby reaching different layers of the water body. Since pollutants and biological activities are usually unevenly distributed at different depths of the water body, this function can more comprehensively deal with water problems and improve the coverage of restoration. The water flow generated by the disrupting mechanism 404 promotes water circulation in the horizontal direction, which not only helps to evenly distribute oxygen and nutrients, but also promotes the mixing and dispersion of suspended particles and pollutants in the water body. By enhancing the dynamics of the water body, the disrupting mechanism 404 can expand the positive impact area of ​​the restoration device on the water body and improve the restoration efficiency. The nitrifying bacteria rich in the culture fiber balls 4034 are dispersed in the disrupting mechanism 404. These bacteria diffuse in the water, accelerating the process of converting ammonia nitrogen into nitrate, which is crucial to reducing eutrophication and improving water quality, thereby further improving the overall restoration effect of the water body; Combining the above three points, the device not only broadens the scope of water body restoration in the vertical and horizontal directions, but also enhances the self-purification ability of the water body by introducing and diffusing nitrifying bacteria. Compared with the single-level restoration method, this multi-dimensional and multi-level restoration strategy can more effectively improve and restore the ecological balance of the water body and improve the restoration efficiency and effect. Therefore, the design of the wetland water body ecological restoration device is an integrated solution, which uses the synergistic effect of physical, chemical and biological processes to achieve the best water body restoration purpose.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
