Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of debris-blocking equipment, specifically a debris-blocking device that facilitates the removal of debris. Background Technology
[0002] The water environment refers to the spatial environment in which water is formed, distributed, and transformed in nature. It refers to the totality of various natural and related social factors surrounding human spaces and water bodies that can directly or indirectly affect human life and development, and their normal functions. The management of the water environment often requires the use of corresponding pollution interception devices to intercept debris in the water and protect the water body.
[0003] Existing debris-blocking devices in water environment management mostly rely on debris-blocking nets immersed in the water to intercept debris. However, during long-term use, a large amount of debris easily adheres to the surface of the debris-blocking nets, resulting in a decrease in water permeability. Since most of the debris-blocking nets are submerged in deep water, it is difficult for users to clean them. This limits the practical application of the device and is not conducive to the efficient implementation of water environment management. In view of this, a debris-blocking device that is easy to clean is proposed. Utility Model Content

[0009] Preferably, both hydraulic actuators are fixedly installed on the lower surface of the support frame cross plate, and the two hydraulic rods are slidably sleeved in the inner walls of the two hydraulic actuators respectively;
[0010] The C-shaped plate is fixedly installed at the lower end of the two hydraulic rods.
[0011] Preferably, the motor is fixedly installed in the inner wall of the C-shaped plate, and the worm gear is fixedly installed at the output end of the motor;
[0012] The worm gear is meshed with the outer surface of the worm, the fixed roller is fixedly sleeved in the inner wall of the worm gear, and the fixed roller is rotatably connected in the inner wall of the C-shaped plate.

[0018] Two scrapers are fixedly installed on the opposite sides of the two upright plates of the support frame.
[0019] (III) Beneficial Effects
[0020] Compared with the prior art, this utility model provides a dirt-blocking device that facilitates the cleaning of debris, and has the following beneficial effects:
[0021] 1. This debris-blocking device, which facilitates cleaning, features a reciprocating motion of the debris-blocking net as it rises. This allows the scraper to fully contact the surface of the net, effectively removing impurities from various locations and preventing residue from affecting the net's filtration efficiency. Compared to static cleaning, this dynamic cleaning method provides a more comprehensive and thorough cleaning of the net, ensuring it maintains excellent debris-blocking performance, extending its service life, and guaranteeing long-term stable operation of the device.
[0022] 2. This debris-blocking device, which facilitates debris removal, automatically locks its worm gear after the motor stops running. This prevents the C-shaped plate and debris-blocking screen driven by the hydraulic rod from sliding down due to gravity, avoiding accidental fall of the screen which could damage the equipment or cause cleaning failure. This transmission method also prevents the reciprocating motion of the screen from becoming disordered due to power fluctuations, making the cam's thrust on the pulley and the spring's reset process more regular. This ensures the stability of the screen's up-and-down movement, allowing the scraper to maintain a uniform scraping force on the screen surface, thus improving the consistency of the cleaning effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-4 This utility model provides a new technical solution: a dirt-blocking device that facilitates the cleaning of debris, including a support frame 1, with grooves 2 opened on the opposite surfaces of the two upright plates of the support frame 1;
[0030] The support frame 1 is equipped with a cleaning mechanism, which includes a hydraulic device 3, a hydraulic rod 4, a C-shaped plate 5, a motor 6, a worm gear 7, a worm wheel 8, a fixed roller 9, a cam 10, a spring 11, a fixed plate 12, a pulley 13, a fixed block 14, a dirt intercepting net 15, and a scraper 16.
[0031] Furthermore, both hydraulic actuators 3 are fixedly installed on the lower surface of the cross plate of the support frame 1, and the two hydraulic rods 4 are slidably sleeved in the inner walls of the two hydraulic actuators 3 respectively.
[0032] The C-shaped plate 5 is fixedly installed at the lower end of the two hydraulic rods 4.
[0033] Furthermore, the motor 6 is fixedly installed in the inner wall of the horizontal plate of the C-shaped plate 5, and the worm gear 7 is fixedly installed at the output end of the motor 6;
[0034] The worm gear 8 is meshed with the outer surface of the worm 7, the fixed roller 9 is fixedly sleeved in the inner wall of the worm gear 8, and the fixed roller 9 is rotatably connected in the inner wall of the C-shaped plate 5.
[0035] Furthermore, two cams 10 are fixedly sleeved on the outer surface of the fixed roller 9, and four springs 11 are fixedly installed in the inner wall of the two vertical plates of the C-shaped plate 5;
[0036] Two fixing plates 12 are respectively fixedly installed on the upper ends of the four springs 11.
[0037] Furthermore, two pulleys 13 are fixedly installed on the upper surfaces of two fixed plates 12, and the two pulleys 13 are in contact with the two cams 10 respectively.
[0038] Furthermore, the two fixing blocks 14 are respectively fixedly installed on the lower surfaces of the two fixing plates 12, and the lower surfaces of the two fixing blocks 14 slide through the lower surfaces of the two vertical plates of the C-shaped plate 5.
[0039] Furthermore, the intercepting net 15 is fixedly installed on the lower surface of the two fixed blocks 14, and the intercepting net 15 is slidably sleeved in the inner wall of the two sliding grooves 2;
[0040] Two scrapers 16 are fixedly installed on the opposite sides of the two vertical plates of the support frame 1;
[0041] When using this debris-blocking device, which facilitates the removal of debris, the hydraulic actuator 3 is activated. The hydraulic actuator 3 drives the hydraulic rod 4, which is slidably mounted on the inner surface, to move upwards. The hydraulic rod 4 then moves the C-shaped plate 5, which is fixedly mounted at its lower end, upwards. The C-shaped plate 5 slides upwards within the inner wall of the chute 2. Simultaneously, the motor 6 is activated. The motor 6 drives the worm gear 7, which is fixedly mounted on its output end, to rotate. The worm gear 7 drives the worm wheel 8, which is meshed with the outer surface, to rotate. The worm wheel 8 drives the fixed roller 9, which is fixedly mounted on the inner surface, to rotate. The fixed roller 9 drives the two cams 10, which are meshed with the outer surface, to rotate. The two cams 10 apply a downward thrust to the pulleys 13, which are in contact with the outer surface. The two pulleys 13 then exert a downward thrust on the lower surface. The two fixed blocks 14 apply a downward pushing force, which in turn applies a downward pushing force to the spring 11 fixedly mounted on the lower surface. The motor 6 continues to operate. At this time, the pulley 13 is no longer in contact with the protruding part of the cam 10, and the spring 11 returns to its original position. The spring 11 then applies an upward pushing force to the fixed plate 12 fixedly mounted at the upper end. The fixed plate 12 drives the two fixed blocks 14 fixedly mounted on the lower surface to apply an upward pulling force. In this way, the fixed blocks 14 move the intercepting screen 15 fixedly mounted on the lower surface upward while simultaneously reciprocating up and down. This reciprocating motion scrapes the scraper 16, removing debris and other impurities from the surface of the intercepting screen 15, thus achieving self-cleaning.
[0042] This debris-blocking device, which facilitates cleaning, uses a reciprocating motion of the debris-blocking screen 15 during its upward movement. This allows the scraper 16 to fully contact the surface of the screen, effectively removing impurities from various locations and preventing residue from affecting the filtration efficiency of the screen. Compared to static cleaning, this dynamic cleaning method provides a more comprehensive and thorough cleaning of the screen, ensuring it maintains excellent debris-blocking performance, extending its service life, and guaranteeing long-term stable operation. When motor 6 stops... After the operation stops, the worm gear 8 and worm 7 can be automatically locked to prevent the C-shaped plate 5 and the intercepting screen 15 driven by the hydraulic rod 4 from sliding down due to gravity. This avoids the intercepting screen 15 falling accidentally and causing equipment damage or cleaning failure. This transmission method can also avoid the disordered reciprocating motion rhythm of the intercepting screen 15 due to power fluctuations, making the thrust of the cam 10 on the pulley 13 and the reset process of the spring 11 more regular, thereby ensuring the stability of the up and down movement of the intercepting screen 15, and ensuring that the scraper 16 and the surface of the intercepting screen 15 always maintain a uniform scraping force, thus improving the consistency of the cleaning effect.
