[0017] [Explanation of Key Component Symbols] 1: Support frame 2: Algae-blocking net 21: Framework 22: Mesh 3: Lifting device 4: Retractable height-adjustable rollers Detailed Implementation

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended purpose of the invention, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation method, structure, features and effects of the movable water quality algae blocking net device structure proposed according to this utility model.

[0019] Please see Figure 1-3 This is a schematic diagram of the various parts of the movable algae-blocking net device of this utility model. The movable algae-blocking net device includes a support frame 1 and an algae-blocking net 2. The support frame 1 includes two vertical supports and a horizontal support connected to the upper end of the two vertical supports. The algae-blocking net 2 is suspended below the horizontal support by a lifting device 3. Each of the two vertical supports is equipped with a retractable height-adjustable roller 4. When the retractable height-adjustable roller 4 is extended, the two vertical supports are lifted off the ground, and the support frame 1 is supported on the ground by the retractable height-adjustable roller 4. When the retractable height-adjustable roller 4 is retracted, the two vertical supports are supported on the ground, and the retractable height-adjustable roller 4 is higher than the ground. This allows the retractable height-adjustable roller 4 to retract when the algae-blocking net 2 does not need to be moved, and the support frame 1 is stably supported on the ground by the two vertical supports. When the algae-blocking net 2 needs to be moved, the retractable height-adjustable roller 4 extends, and the support frame 1 can easily move the algae-blocking net 2 by means of the retractable height-adjustable roller 4.

[0020] In this embodiment, the lifting device 3 includes a lifting motor, a winding drum, and a pull rope. The lifting motor and the winding drum are fixed to the bottom of the horizontal support. One end of the pull rope is wound and fixed to the winding drum, and the other end is fixed to the top of the algae-blocking net 2. The lifting motor drives the winding drum to rotate, thereby realizing the winding and unwinding of the rope and thus achieving the purpose of moving the algae-blocking net 2 vertically. A pull ring is provided in the middle of the top of the algae-blocking net 2, and the pull rope is fixed to the pull ring, so as to pull the algae-blocking net 2.

[0021] The algae-blocking net 2 includes a frame 21 and mesh panels 22. The frame 21 is used to maintain the stable shape of the mesh panels 22 to achieve the algae-blocking function. In this embodiment, the frame 2 is in the shape of a grid, and there are four mesh panels 22, which fill the spaces in the frame 2, but it is not limited to this.

[0022] The algae-blocking net 2 has at least two sliding wheels 23 on each side of its frame 21, meaning that at least two sliding wheels 23 are distributed along the height direction on both the left and right sides of the frame 21. These sliding wheels 23 are used to slide and engage with the walls on both sides of the water distribution outlet, enabling the algae-blocking net 2 to slide and guide when lowered and raised. Preferably, each side of the frame 21 has two sliding wheels 23, with one sliding wheel 23 positioned closer to the upper end and the other closer to the lower end.

[0023] The retractable height-adjustable roller 4 includes a support portion fixed to one side of a vertical bracket and a roller. The support portion has a threaded hole running vertically through it. The roller is rotatably mounted on a roller bracket, on which a lead screw is fixed. The upper part of the lead screw has an external thread that matches the threaded hole in the support portion. The lead screw is locked to the support portion by a nut. When the algae-blocking net does not need to be moved, the upper end of the lead screw extends a considerable length beyond the support portion, causing the bottom of the roller to be higher than the ground. When the algae-blocking net needs to be moved, the lead screw is adjusted downwards, allowing the roller to rest on the ground. The roller has a locking function, allowing it to lock in place after being moved into position.

[0024] In this embodiment, the vertical support includes a vertical support rod 11, inclined reinforcing rods 12 symmetrically supported on both sides of the vertical support rod 11, and a connecting rod 13 connecting the bottom of the vertical support rod 11 and the reinforcing rods 12. The retractable height-adjustable roller 4 is located on one side of the connecting rod 13. The connection rod 13 and the reinforcing rod 12 not only increase the contact area between the vertical support and the ground, but also form a stable triangular support structure, ensuring the stability of the vertical support. A reinforcing rod 14 is also provided between the vertical support rod 11 and the horizontal support to enhance the connection strength between them. The reinforcing rod 14, the vertical support rod 11, and the horizontal support form a triangular structure.

[0025] In this embodiment of the invention, the support frame 1 has two sets of retractable height-adjustable rollers on each side of its bottom. These rollers are driven by a screw and nut to flexibly switch between support and movement functions. In normal standby mode, the bottom of the rollers is higher than the bottom surface of the support frame, and the device is stably placed in the designated area. When algae-blocking operations need to be initiated, the retractable height-adjustable rollers are adjusted to extend downwards until the bottom surface of the support frame is off the ground. At this point, the device can be easily moved to a position above the gate opening using the rollers. After the operation is completed, the retractable height-adjustable rollers are adjusted to retract, and the device returns to a stable support state after the bottom surface of the support frame has fully contacted the ground.

[0026] In this embodiment, the retractable height-adjustable roller 4 is made of high-strength, corrosion-resistant material. The lead screw and roller body are forged from Q235B high-strength carbon steel, and the surface is treated with hot-dip galvanizing, with a zinc layer thickness ≥80μm. This resists electrochemical corrosion in the humid environment surrounding water bodies, ensuring a maintenance-free service life of more than 5 years. The roller has a built-in 6203 deep groove ball bearing, filled with lithium-based grease, resulting in a rotational friction coefficient as low as 0.0015. Under no-load conditions, a single person's thrust ≤15N is sufficient to move the device. The lead screw and nut pair (5mm pitch) used in this invention can achieve stepless height adjustment from 0-120mm, allowing the roller to quickly switch between support and retracted states, reducing the motor response time to 1 / 5 of the traditional method.

[0027] This invention allows for the extension and retraction control of the rollers by rotating the screw clockwise or counterclockwise. Actual test data shows that a single person can complete a full relocation of the device (including height adjustment and positioning) in just 3 minutes, saving 80% of labor costs compared to traditional handling methods. In emergency scenarios such as algal blooms, this structure can be rapidly deployed to the gate location within 5 minutes to initiate algal interception operations, significantly improving emergency response efficiency.

[0028] This utility model features a telescopic height-adjustable roller 4 that uses a lead screw to extend and retract, requiring minimal distance between the top of the algae-blocking device and the roof, enabling flexible movement in narrow spaces with dense equipment, such as pump rooms and gate chambers.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
