Abstract

This utility model discloses a biowall for river water maintenance. A motor-driven shaft rotates a bidirectional threaded motion, controlling the microbial packing mesh to flexibly switch between an inclined state (guiding water flow) and a horizontal state (facilitating cleaning). The inclined state alters the water flow direction, significantly reducing the direct impact and adhesion probability of suspended solids on the mesh, thus minimizing the risk of blockage at the source. When the mesh is switched to a horizontal state, the cleaning cone precisely aligns with the mesh openings (one-to-one position). Simply pushing the I-shaped slider manually allows the cleaning cone to penetrate the mesh for physical unblocking. No hoisting or disassembly of the mesh is required, enabling rapid in-situ cleaning and significantly reducing maintenance difficulty and time costs.

Description

Technical Field

[0001] This utility model relates to the field of biowall technology, specifically a biowall for river water body maintenance. Background Technology

[0002] With increasingly stringent requirements for water environment protection, ecological restoration and maintenance technologies for river water bodies have received widespread attention. Among these, utilizing microbial biofilm for water purification is a highly efficient and eco-friendly method. A common practice involves fixing microbial packing materials (such as packing mesh panels or biofilm strips) in the river channel. These mesh panels are constantly submerged in flowing water, making it easy for suspended particles (such as silt, algae, and organic debris) carried by the water to adhere to the mesh surface and clog the mesh openings. This clogging severely hinders effective contact and exchange between the water and the packing materials and attached microorganisms, leading to decreased microbial activity and significantly reducing the water purification efficiency. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a biowall for river water body maintenance. The technical solution adopted includes an installation frame, a cleaning part, a rotating shaft, a motor, a bottom fixing shaft, a mating block, a vertical connecting rod, a front mounting shaft, a front mounting block, a fixing shaft, a microbial packing mesh plate, mesh holes, an inner sleeve shaft, and a middle plate. The cleaning part is set at the top of the installation frame. It is operated regularly to clean the mesh holes on the microbial packing mesh plate to prevent the mesh holes from clogging. The motor is fixedly installed on the right side of the installation frame near the top. The output shaft of the motor extends into the installation frame from a through hole on the right side of the installation frame and is fixedly connected to the rotating shaft at the end of the output shaft. The left end of the rotating shaft... The device is rotatably connected to the inner wall of the mounting frame. This rotatable connection employs common mechanical connection methods, such as bearing-mounted shafts. The shaft has bidirectional threads, and a bottom fixed shaft is fixed to the lower end of the mounting frame. An upper mating block engages with the threaded portion of the shaft, while a lower mating block is movably mounted on the bottom fixed shaft. The bottom fixed shaft is coated with a corrosion-resistant, hydrophobic coating (such as PTFE coating), significantly reducing the probability of aquatic organism attachment and silt deposition. Simultaneously, a self-lubricating bearing (such as a graphite copper sleeve) is embedded within the protruding block, with its inner diameter clearance-fitted to the outer diameter of the bottom fixed shaft, leaving a 0. A 5-1mm dynamic compensation space ensures smooth sliding even with trace amounts of dirt. Furthermore, the motor drive torque has a 300% safety margin (rated load 10N·m, motor output 30N·m) to overcome temporary dirt adhesion. During use, the top of the mounting frame and the motor are positioned above the water surface to prevent debris from remaining in the threads and affecting transmission. Vertical connecting rods are fixedly connected between the upper and lower mating blocks. The front side of the mating blocks is fixedly mounted to the front side mounting block via a fixed front mounting shaft. A fixed shaft is fixedly connected between the upper and lower front mounting blocks. Intermediate plates are fixedly connected to the upper and lower ends of the inner sleeve shaft. (Microbial packing mesh) The plate has several mesh holes. The inner and outer ends of the microbial packing mesh plate have vertical through holes. The inner end is movably fitted onto the fixed shaft through the through holes, and the inner end is movably fitted onto the inner sleeve shaft through the through holes. The motor is battery powered and controlled by a remote-controlled rotating shaft. After starting, it drives the rotating shaft to rotate. Under the action of the threaded grooves distributed on it, it approaches or moves away from the mating blocks on the left and right sides. During this process, the state of the two microbial packing mesh plates will also change, being in an inclined state, a horizontal state in the left and right directions, or a horizontal state in the front and back directions. The inclined microbial packing mesh plate can guide the water flow, and the inclined setting can effectively reduce the risk of mesh blockage.

[0004] As a preferred technical solution of this utility model, the cleaning part includes a top T-shaped track groove, an I-shaped slider, a vertical connecting plate, a cleaning mounting plate, and cleaning cones. The top surface of the mounting frame has a top T-shaped track groove, and the I-shaped slider is placed in the top T-shaped track groove. The vertical connecting plate is integrally formed below the front end of the upper horizontal part of the I-shaped slider. The cleaning mounting plate is fixed at the lower end of the vertical connecting plate. Several cleaning cones are evenly distributed on the side of the cleaning mounting plate. The cleaning cones are made of stainless steel. The outer wall of the I-shaped slider abuts against the inner wall of the T-shaped track groove, that is, the existing friction limits it. It can be stably placed in the T-shaped track groove without external force. When cleaning is required, the I-shaped slider is manually pushed to move the cleaning cones towards the microbial packing mesh plate to clean the mesh.

[0005] As a preferred technical solution of this utility model, when the microbial packing mesh plate is in the front-back direction, the positions of several mesh holes on it correspond one-to-one with the positions of each cleaning cone.

[0006] As a preferred embodiment of this utility model, a flexible mesh is connected between the vertical connecting rod and the inner wall of the mounting frame.

[0007] As a preferred technical solution of this utility model, a through groove is opened at the bottom of the mounting frame, and a protruding block is integrally formed at the bottom of the mating block at the bottom. The protruding block is placed in the through groove, and its outer wall is in contact with the inner wall of the through groove.

[0008] The beneficial effects of this invention are as follows: A motor-driven rotating shaft drives a bidirectional threaded motion, allowing the microbial packing mesh plate to flexibly switch between an inclined state (guiding water flow) and a horizontal state (facilitating cleaning). The inclined state changes the water flow direction, significantly reducing the direct impact and adhesion probability of suspended solids on the mesh, thus reducing the risk of blockage at the source. When the mesh plate switches to a horizontal state, the cleaning cone precisely aligns with the mesh openings (one-to-one position), requiring only manual pushing of the I-shaped slider to drive the cleaning cone through the mesh for physical unblocking. No lifting or disassembly of the mesh plate is required, enabling rapid in-situ cleaning and significantly reducing maintenance difficulty and time costs. Attached Figure Description

The cleaning section is provided at the top of the installation frame 1. The motor 8 is fixedly installed on the right side of the installation frame 1 near the top. The output shaft of the motor 8 extends from a through hole on the right side of the installation frame 1 into the installation frame 1 and is fixedly connected to the rotating shaft 7 at the end of the output shaft. The left end of the rotating shaft 7 is rotatably connected to the inner wall of the installation frame 1. The rotating shaft 7 has a bidirectional thread. The lower end of the installation frame 1 is fixed. A bottom fixed shaft 9 is fixed. The upper mating block 10 is installed in conjunction with the threaded part on the rotating shaft 7. The lower mating block 10 is movably fitted on the bottom fixed shaft 9. A vertical connecting rod 11 is fixedly connected between the upper and lower mating blocks 10. A front mounting block 131 is fixedly installed on the front side of the mating block 10 through a fixed front mounting shaft 12. A fixed shaft 13 is fixedly connected between the upper and lower front mounting blocks 131. An intermediate plate 17 is fixedly connected to both the upper and lower ends of the inner sleeve shaft 16. A number of mesh holes 15 are respectively on the microbial packing mesh plate 14. The inner and outer ends of the microbial packing mesh plate 14 have vertical through holes. The inner end is movably fitted on the fixed shaft 13 through the through hole and the inner end is movably fitted on the inner sleeve shaft 16 through the through hole.

[0014] As a preferred technical solution of this utility model, the cleaning part is specifically set up as follows: a top T-shaped track groove 2 is opened on the top surface of the mounting frame 1, and the I-shaped slider 3 is placed in the top T-shaped track groove 2. The upper horizontal part of the I-shaped slider 3 has an integrally formed vertical connecting plate 4 below the front end. A cleaning mounting plate 5 is fixed at the lower end of the vertical connecting plate 4. Several cleaning cones 6 are evenly distributed on the side of the cleaning mounting plate 5. The cleaning cones 6 are made of stainless steel.

[0015] As a preferred technical solution of this utility model, when the microbial packing mesh plate 14 is in the front-back direction, the positions of several mesh holes 15 on it correspond one-to-one with the positions of each cleaning cone 6.

[0016] As a preferred technical solution of this utility model, a flexible net 111 is connected between the vertical connecting rod 11 and the inner wall of the mounting frame 1.

[0017] As a preferred technical solution of this utility model, the lower part of the mounting frame 1 has a through groove 101, and the bottom of the lower mating block 10 has an integrally formed protrusion 102. The protrusion 102 is placed in the through groove 101, and its outer wall is in contact with the inner wall of the through groove 101.

[0018] The working principle of this utility model is as follows: During use, the motor (battery powered) is remotely started. The motor output shaft drives the rotating shaft to rotate. The bidirectional thread on the rotating shaft drives the upper mating block, which meshes with it, to move horizontally. The lower mating block slides synchronously along the bottom fixed shaft (the protrusion guides and limits movement within the through groove). The upper and lower mating blocks are rigidly connected by a vertical connecting rod, enabling synchronous opposite or reversible movement. When the mating blocks move, the front mounting shaft drives the front mounting block to move, causing the fixed shaft fixed between the upper and lower front mounting blocks to translate accordingly. The inner end of the microbial packing mesh is fitted onto the fixed shaft, and the outer end is fitted onto the inner sleeve shaft (the inner sleeve shaft is fixed to the mounting frame via a middle plate). The mesh rotates around the fixed shaft, forming a circle with... The water flow is inclined at an angle, and the inclined mesh plate changes the direction of the water flow, preventing suspended matter from impacting the mesh vertically. Under the action of gravity and water flow shear force, the particles slide down the inclined surface, significantly reducing the probability of blockage. The motor is remotely controlled to reverse, driving the mating block to move to the limit position. The microbial packing mesh plate switches to a horizontal state in the front and back direction (the mesh is facing the cleaning part). The I-shaped slider is manually pushed horizontally (moving along the top T-shaped track groove). The slider drives the cleaning mounting plate and cleaning cone to move forward through the vertical connecting plate. The cleaning cone is precisely inserted into the corresponding mesh (the position is designed to correspond one-to-one), physically penetrating and removing the blockage. After cleaning, the I-shaped slider is pulled back in the opposite direction and is fixed by the friction between the T-shaped groove and the slider.
