Description

A biomimetic aquatic plant river purification device Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a biomimetic aquatic plant river purification device. Background Technology

[0002] With urbanization and dense population growth, water pollution in rivers and lakes has become increasingly serious. Although technological advancements have continuously improved wastewater treatment technologies and capabilities, the cost of water treatment has also risen significantly. In recent years, the method of artificially introducing bionic aquatic plants has been increasingly applied to river wastewater treatment. Artificial bionic aquatic plants provide a carrier for pollution-resistant algae and bacteria in eutrophic or polluted water bodies, simulating and reconstructing the natural ecosystem of aquatic plants and water bodies, improving water transparency, enhancing the self-purification capacity of water bodies, inhibiting eutrophication, and restoring the aquatic environment. Currently, when using bionic aquatic plants, horizontal ropes are typically erected between the banks of the river, and the bionic aquatic plants are evenly tied to these ropes. Because both the horizontal ropes and the bionic aquatic plants are flexible, the plants have a high degree of freedom of movement with the water flow, making them prone to entanglement. Summary of the Invention

[0003] The purpose of this invention is to provide a biomimetic aquatic plant river purification device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a biomimetic aquatic plant river purification device, comprising guide channels and biomimetic aquatic plants set on both sides of the river channel. The guide channels are formed by concrete casting. Matching floats are set in the guide channels. A telescopic frame is connected between two opposite floats. The telescopic frame includes a scissor mechanism and several crossbars. The crossbars are longitudinally connected between two opposite hinge points of the scissor mechanism. Several U-shaped supports are welded to the lower side of the crossbars. The supports are provided with transverse through holes for threading transverse first pull ropes. An aeration pipe is installed on the riverbed directly below the telescopic frame. Several transverse second pull ropes are connected in the aeration pipe. The first pull ropes and the second pull ropes are vertically opposite each other and connected between them by several evenly distributed biomimetic aquatic plants. Several evenly distributed rotating aeration discs are installed on the aeration pipe.

[0005] The rotating aeration disc includes a trumpet-shaped outer cover and a cylindrical mounting base. A microporous membrane is installed at the upper end of the outer cover, and a horizontal support plate is provided in the inner cavity of the outer cover. A downwardly extending circular tube is fixedly installed in the middle of the support plate. The circular tube is inserted into the inner cavity of the mounting base and rotatably connected to it through a bearing. A spiral blade is fixedly connected to the inner wall of the circular tube.

[0006] Preferably, the crossbar is a square tube made of aluminum alloy, and the crossbar has an elongated hole along its length, which is slidably connected to the hinge point of the scissor mechanism.

[0007] Preferably, a check valve is installed at the lower end of the round tube, an end plate for sealing is provided at the top end of the round tube, a through hole for venting is provided on the top side of the round tube, and an internal thread is provided at the lower end of the mounting base.

[0008] Preferably, the upper side of the tray is provided with a vortex guide plate, the upper side of which abuts against the bottom of the microporous membrane, and the vortex guide plate rotates in the same direction as the helical blade.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model arranges the bionic aquatic plants between the telescopic frame and the aeration mechanism, reducing the degree of freedom of the bionic aquatic plants and reducing the probability of entanglement. At the same time, aeration can promote the growth and reproduction of aerobic bacteria on the bionic aquatic plants. The telescopic frame is installed between the two floating boxes and can rise and fall with the water level, ensuring that the bionic aquatic plants are immersed in the water as much as possible.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please refer to Figures 1-4. This utility model provides a technical solution: a biomimetic aquatic plant river purification device, including a guide channel 1 and a biomimetic aquatic plant 5 (a three-dimensional carrier constructed with PP+K-45 biological rope as the core) set on both sides of the river. The guide channel 1 is formed by concrete casting, and a matching float 2 is set in the guide channel 1. The float 2 is made of plastic. A telescopic frame 3 is connected between two opposing pontoons 2. The telescopic frame 3 includes a scissor mechanism 31 and several crossbars 32. The crossbars 32 are longitudinally connected between two opposing hinge points of the scissor mechanism 31. The crossbars 32 are made of aluminum alloy square tubes and have elongated holes 33 along their length. The elongated holes 33 are slidably connected to the hinge points of the scissor mechanism 31. Several U-shaped supports 34 are welded to the lower side of the crossbars 32. The supports 34 have transverse through holes for threading through the first horizontal pull rope 4. An aeration pipe 6 is installed on the riverbed directly below the telescopic frame 3. Several transverse second pull ropes are connected in the aeration pipe 6. The first pull rope 4 and the second pull rope are vertically opposite each other and connected by several evenly distributed biomimetic aquatic plants 5. Since the upper and lower ends of the biomimetic aquatic plants are fixed, it helps to reduce the probability of tangling.

[0017] Multiple evenly distributed rotating aeration discs 7 are installed on the aeration pipe 6. The input end of the aeration pipe 6 is connected to a blower or air compressor. The rotating aeration discs 7 include a trumpet-shaped outer cover 71 and a cylindrical mounting base 72. A microporous diaphragm 74 is installed at the upper end of the outer cover 71. A horizontal support plate 73 is provided in the inner cavity of the outer cover 71. A downwardly extending circular tube 75 is fixedly installed in the middle of the support plate 73. The circular tube 75 is inserted into the inner cavity of the mounting base 72 and is rotatably connected to it through a bearing. A spiral blade 77 is fixedly connected to the inner wall of the circular tube 75. When compressed air passes through the circular tube 75, a rotational torque is generated due to the guiding effect of the spiral blade 77. A check valve is installed at the lower end of the circular tube 75. An end plate for sealing is provided at the top end of the circular tube 75. A through hole for exhaust is provided on the top side of the circular tube 75. The lower end of the mounting base 72 is provided with an internal thread. A vortex guide plate 76 is provided on the upper side of the support plate 73. The upper side of the vortex guide plate 76 abuts against the bottom of the microporous membrane 74. The vortex guide plate 76 rotates in the same direction as the spiral blade 77. The vortex guide plate 76 is used to evenly distribute compressed air on the microporous membrane 74. The dissolved oxygen content of the water is increased by aeration, which promotes the growth of aerobic bacteria. The aeration disc 7 can rotate during operation, which helps to reduce the deposition and coverage of silt and impurities on it, while improving the uniformity of aeration.

[0018] Working principle: The telescopic frame 7 serves as the installation framework for the bionic aquatic plants. The telescopic frame 7 is adjustable in length within a certain range, facilitating quick and easy on-site assembly. Both ends of the telescopic frame 7 are installed with the float box 2, automatically adjusting its height according to the water level to ensure that the bionic aquatic plants 5 are immersed in the water as much as possible. An aeration mechanism (including aeration pipe 6 and aeration disc 7) is arranged on the riverbed below the telescopic frame 7 to increase water volume and promote the growth of aerobic bacteria. Simultaneously, the aeration mechanism is used to fix the lower end of the bionic aquatic plants 5, reducing tangling.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
