Description

Technical Field

[0001] This invention belongs to the field of trash rack technology, and particularly relates to a floating trash rack mechanical grid structure that can adapt to changes in water level. Background Technology

[0002] A debris screen is a filtration device installed at the inlet of water supply, drainage, sewage treatment, and water conservancy projects. Its core function is to intercept floating solid debris in the water, such as branches, plastics, household waste, and silt, preventing them from entering subsequent treatment facilities or water conservancy equipment, causing pipe blockage, equipment wear, or even damage, and ensuring the stable operation of the entire system. Structurally, a trash rack is generally composed of a metal frame and bars arranged at a certain interval. The bars are mostly made of corrosion-resistant and high-strength materials such as stainless steel and galvanized steel. The spacing between the bars can be adjusted according to the type of debris in the water and the flow rate. They are divided into three categories: coarse bars, medium bars, and fine bars.

[0003] As a core pre-treatment facility for water treatment and water conservancy projects, trash racks can effectively reduce the treatment load of subsequent processes, improve water treatment efficiency, and extend the service life of equipment such as pumps and valves. They are widely used in urban sewage treatment plants, waterworks, hydropower stations, pumping stations and other places.

[0004] Existing debris barriers are mostly fixed structures, which cannot flexibly adjust their position and status according to changes in water level. This results in the barrier being suspended when the water level rises, allowing a large amount of floating garbage to overflow and leak. When the water level drops, the barrier is exposed and loses its debris-blocking function. Once the water level fluctuates, the entire debris-blocking process becomes completely ineffective.

[0017] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0018] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] Please see Figures 1 to 7 This invention provides a floating debris barrier mechanical grid structure that can adapt to changes in water level, comprising: a base frame 1; two symmetrically arranged first support frames 2, the first support frames 2 being fixedly connected to the upper side of the base frame 1; a grid assembly, the grid assembly being installed on the base frame 1 for adapting to changes in water level and for debris interception; and a cleaning assembly, the cleaning assembly being installed on the first support frames 2; wherein, the grid assembly includes two first connecting rods 3 rotatably connected to the base frame 1, the first connecting rods 3 being located in the middle position of the base frame 1, and a second connecting rod 4 rotatably connected to each of the first support frames 2.

[0020] Using the above solution: When using the bar screen, the staff moves it to the designated placement area, adjusts the vertical angle of the bar screen assembly so that the bottom is submerged in water and fixed. The bar screen assembly makes the base frame 1 float on the water surface and can be adaptively adjusted according to the water level. When using the bar screen assembly for debris interception, the cleaning component continuously contacts the bar screen assembly to make it vibrate and shake off the debris, so that the bar screen assembly can continuously and effectively intercept debris and improve the efficiency of debris interception.

[0021] Furthermore, the inner sides of the two first connecting rods 3 and the two second connecting rods 4 are rotatably connected to the grid body 5.

[0022] Furthermore, the base frame 1 has two symmetrically arranged floats 6 on its lower side; each float 6 has two symmetrically arranged telescopic rods 7 fixedly connected to its upper side, and the fixed end of the telescopic rod 7 is fixedly connected to the upper side of the base frame 1; a plurality of first springs 8 are fixedly connected between the base frame 1 and the floats 6, and the first springs 8 are sleeved on the outside of the telescopic rods 7.

[0023] Furthermore, a second support frame 9 is fixedly connected to both the left and right sides of the base frame 1; a retractable shaft 10 is rotatably connected to the second support frame 9; two symmetrically arranged chain ropes 11 are wound around the retractable shaft 10, one end of the chain rope 11 is fixedly connected to a first fixing plate 12, and a fixing anchor 13 is fixedly connected to the lower side of the first fixing plate 12.

[0024] Furthermore, a perforated plate 14 is fixedly connected between the four first fixing plates 12; a support wheel 16 is rotatably connected to the bottom of the grid body 5; a fixing rope 17 is fixedly connected to the upper side of the perforated plate 14; the other end of the fixing rope 17 is wrapped around the lower side of the grid body 5, and the fixing rope 17 is attached to the support wheel 16.

[0025] Using the above scheme: In use, the float 6 is placed on the water surface to support the base frame 1. The grid body 5 is pushed to rotate the two first connecting rods 3 and the second connecting rod 4, causing the grid body 5 to flip to a vertical angle and the bottom to be submerged in water. The fixing rope 17 is fixed to the hollow plate 14. The retraction shaft 10 is driven to rotate and lower the chain rope 11. The fixing anchor 13 drives the hollow plate 14 to move down. The fixing anchor 13 falls into the water to fix the float 6. The float 6 does not drift laterally under the impact of the water flow. Then the retraction shaft 10 is fixed, and the other end of the fixing rope 17 is fixed to the lower side of the grid body 5. Through the action of the fixing rope 17, it is kept at the required angle. When the water level rises, the float 6 drives the base frame 1 and the entire grid to float upward. When the water level drops, the float 6 sinks with the water level, thereby realizing the floating function that can adapt to changes in water level. Subsequently, the grid body 5 can be used to intercept sewage.

[0026] It should be noted that: First, when the launching and retracting shaft 10 does not need to rotate, it can be fixed by a fixing mechanism (e.g., ratchet and pawl) to prevent the anchor 13 from moving downwards. The appropriate fixing mechanism can be used according to actual needs. Second, the chain rope 11 and the fixing rope 17 are not in a taut state, so they work in conjunction with the float 6 to change the water level.

[0027] Furthermore, the cleaning assembly includes: a third link 18 rotatably connected to the first support frame 2; a second fixing frame 19 is fixedly connected between the third link 18, a first bearing frame 20 is slidably connected inside the second fixing frame 19, and a limit frame 21 is fixedly connected to one side of the first bearing frame 20.

[0028] Furthermore, two symmetrically arranged guide rods 22 are fixedly connected to the limiting frame 21; a first slider 23 is slidably connected to the guide rod 22, and a second spring 24 is fixedly connected between the first slider 23 and the limiting frame 21, with the second spring 24 sleeved on the outside of the guide rod 22.

[0029] Furthermore, a first motor 25 is mounted on the first support frame 2; a drive wheel 26 is fixedly connected to the output end of the first motor 25; A guide shaft 27 is slidably connected to the limiting frame 21. One end of the guide shaft 27 is rotatably connected to the drive wheel 26, and the other end of the guide shaft 27 is fixedly connected to the first slider 23.

[0030] Furthermore, a push rod 28 that can contact the grid body 5 is fixedly connected to the first slider 23, and a threaded rod 29 is rotatably connected to the second fixing frame 19; the first slider 23 is threadedly connected to the threaded rod 29, a second motor 30 is installed on the third connecting rod 18, one end of the threaded rod 29 is fixedly connected to the output end of the second motor 30, and a water flow detection sensor 15 is fixedly connected to the bottom of the first support frame 20.

[0031] Using the above scheme: During use, when removing impurities from the screen body 5, the second motor 30 drives the threaded rod 29 to rotate, pushing the first support frame 20 to drive the limiting frame 21 to reciprocate on the second fixed frame 19. The first motor 25 causes the drive wheel 26 to rotate, which, in conjunction with the guide shaft 27, converts the rotational motion into the reciprocating linear motion of the first slider 23. The first slider 23 moves on the guide rod 22 and compresses the second spring 24, causing the push rod 28 to contact the screen and vibrate it. The centrifugal force of the vibration removes impurities from the screen surface. When the first support frame 20 moves, it drives the water flow detection sensor 15. Synchronous displacement detects water flow velocity and direction. Simultaneously, through the action of the telescopic rod 7 and the first spring 8, the vibration energy of the grid body 5 is transmitted through the base frame 1 to the float 6 and anchor chain, causing the float 6 and chain rope 11 to vibrate slightly. The vibration peels away aquatic plants, silt, algae and floating debris from the surface of the grid, allowing them to be carried away by the water flow. The first support frame 20 can move to clean different areas of the grid body 5. The slight vibration of the float 6 and chain rope 11 prevents moss and aquatic plants from adhering and depositing on the outer wall of the float 6 and prevents silt from burying the chain rope 11. The water flow detection sensor 15 realizes mobile scanning to detect water flow velocity and direction.

[0032] It should be noted that drive wheel 26 is an eccentric cam.

[0033] Working principle of the invention: When using the bar screen, the operator moves it to the designated placement area, places the float 6 on the water surface supporting the base frame 1, and pushes the bar screen body 5 to rotate the two first connecting rods 3 and the second connecting rod 4. The bar screen body 5 flips to a vertical angle, with its bottom submerged in water. The fixing rope 17 is fixed to the perforated plate 14, and the drive shaft 10 is rotated to lower the chain rope 11. The fixing anchor 13 drives the perforated plate 14 to move down, and the fixing anchor 13 falls into the water to fix the float 6. The float 6 does not drift laterally under the impact of the water flow. Then, the drive shaft 10 is fixed, and the other end of the fixing rope 17 is fixed to the lower side of the bar screen body 5. Through the action of the fixing rope 17, it maintains the required angle. When the water level rises, the float 6 drives the base frame 1 and the entire bar screen to float upward. When the water level drops, the float 6 sinks with the water level, thus realizing a floating function that can adapt to changes in water level. Subsequently, the bar screen body 5 can be used to intercept sewage. When removing impurities from the bar screen body 5, the second motor 30 drives the threaded rod 29 to rotate, pushing the first support frame 20 to drive the limit frame. 21 reciprocates on the second fixed frame 19. The first motor 25 causes the drive wheel 26 to rotate, which, in conjunction with the guide shaft 27, converts the rotational motion into the reciprocating linear motion of the first slider 23. The first slider 23 moves on the guide rod 22 and compresses the second spring 24, causing the push rod 28 to contact the grid and vibrate it. The centrifugal force of the vibration removes impurities from the grid surface. When the first support frame 20 moves, it drives the water flow detection sensor 15 to move synchronously, detecting the water flow velocity and direction. At the same time, through the telescopic rod 7 and the first... The function of the spring 8 is to transmit the vibration energy of the grid body 5 through the base frame 1 to the float 6 and the anchor chain, causing the float 6 and the chain rope 11 to vibrate slightly. Through vibration, the aquatic plants, silt, algae and floating debris on the surface of the grid are peeled off and carried away by the water flow. The first support frame 20 can move to clean different areas of the grid body 5. The slight vibration of the float 6 and the chain rope 11 prevents moss and aquatic plants from adhering and depositing on the outer wall of the float 6 and prevents silt from burying the chain rope 11. The water flow detection sensor 15 realizes mobile scanning to detect the water flow speed and direction.
