Description

Technical Field

[0001] This utility model relates to the technical field of water channel grid structure, and in particular to a water channel grid structure for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. A grating is a structure used in water channels to filter garbage. After a period of use, the grating needs to be cleaned regularly to ensure the stability of water flow. A novelty search revealed a water channel grating structure for water conservancy engineering design (publication number: CN220183955U), including an installation frame and a cleaning structure. The installation frame has symmetrically formed limiting grooves on both sides, and a dividing block is fixedly installed at the center of the bottom of the installation frame. The top of the dividing long block is symmetrically equipped with columns. One end of each set of columns is connected to a rotating shaft between it and the inner wall of the mounting frame. Gears are fixedly installed on the outer surface of the rotating shaft. The two sides of the dividing long block are symmetrically provided with slots. A barrier grid and an auxiliary grid are movably installed in the two sets of slots, respectively. This water conservancy engineering design water channel grid structure can prevent the water in the channel from having a gap period to block impurities when cleaning after the grid is disassembled. It can also be cleaned without disassembling the grid to prevent excessive impurities from clogging the grid and to reduce the workload of workers cleaning the grid.

[0003] The aforementioned patent discloses a water channel grid structure for hydraulic engineering design. When cleaning impurities on the grid, a moving scraper is used. This cleaning method has the following shortcomings: 1. When the scraper moves, impurities clogging the grid mesh are difficult to remove, resulting in unsatisfactory cleaning; 2. There is no structure for collecting the removed impurities. The filtered impurities are directly pushed to one side, and during subsequent water flow, these impurities will again clog the grid, failing to achieve a thorough cleaning effect. Considering the above, this application proposes a new water channel grid structure for hydraulic engineering. Utility Model Content

[0030] Mounting plate 1 and fixing plate 101 cooperate to fix and support the grid frame 2. The top of fixing plate 101 has two bolt holes, which, when used with external bolts, allow the entire device to be fixed in the corresponding position within the water channel.

A movable back-blowing cleaning mechanism 5 for cleaning the grid 201 is installed on the horizontal plate 4. The movable back-blowing cleaning mechanism 5 includes a horizontal pipe 503 located above and behind the grid 201. Both ends of the horizontal pipe 503 are sealed. Multiple air blowing heads 504 are fixedly connected to the front of the horizontal pipe 503. The air blowing heads 504 blow air to back-blow and clean the grid 201. A high-pressure air pump 501 is fixedly connected to the top of the horizontal plate 4. The top of the high-pressure air pump 501 is the extraction end and is fixedly connected to a dustproof net to block dust in the extracted air.

The telescopic characteristics of the telescopic hose 502 provide a vertical movement distance for the horizontal tube 503. The top of the horizontal plate 4 is fitted with a multi-stage electric telescopic rod 505. The top of the horizontal plate 4 has a mounting hole for fixing the multi-stage electric telescopic rod 505. The bottom end of the output shaft of the multi-stage electric telescopic rod 505 is fixedly connected to the top of the horizontal tube 503.

The right side of the high-pressure air pump 501 is fixedly connected with a timer control switch 506.

The timer control switch 506 sets the opening and closing time of the high-pressure air pump 501 and the multi-stage electric telescopic rod 505.

[0031] A solar power supply mechanism 6 for power supply is installed on the top right side of the horizontal plate 4. The solar power supply mechanism 6 includes a solar panel 601 fixedly installed on the top of the horizontal plate 4. Two support rods of different lengths are fixedly connected to the top of the horizontal plate 4. The top of the support rods is fixedly connected to the bottom of the solar panel 601. The support rods are used to support the solar panel 601. A battery 602 is fixedly installed on the top of the horizontal plate 4 below the solar panel 601. An inverter 603 is fixedly and electrically connected to the top of the battery 602. The battery 602 is electrically connected to the solar panel 601. The inverter 603 is electrically connected to the high-pressure air pump 501 and the multi-stage electric telescopic rod 505. Then, the battery 602 supplies power to the high-pressure air pump 501 and the multi-stage electric telescopic rod 505 through the inverter 603. Through a series of structural settings, this utility model can backflush the mesh of the grid 201 to clean impurities, which can effectively reduce the risk of grid 201 mesh blockage, improve the cleaning effect, and collect and centrally clean the cleaned impurities, which can prevent the cleaned impurities from blocking the grid 201 again, achieving the effect of thorough cleaning of impurities. In addition, while lifting the counterweight collection box 301 to move upward, it can also drive the guide scraper 307 to scrape and clean the impurities on the front side of the grid 201 again, further improving the cleaning effect.

[0032] Working principle: When in use, the entire device can be fixed at the drainage position of the water conservancy project canal by using the fixing plate 101 with bolt holes and external bolts. Water in the canal can pass through the grid 201 and be discharged. The grid 201 filters impurities in the water. During use, the solar panel 601 absorbs external solar energy and converts it into electrical energy stored in the battery 602. The inverter 603 converts DC power into AC power to power the high-pressure air pump 501 and the multi-stage electric telescopic rod 505.

[0033] The opening and closing times of the high-pressure air pump 501 and the multi-stage electric telescopic rod 505 are preset via a timer control switch 506. When the opening time is reached, the timer control switch 506 controls the high-pressure air pump 501 and the multi-stage electric telescopic rod 505 to turn on. When the high-pressure air pump 501 turns on, it draws in external gas through its extraction end. The drawn gas enters the horizontal tube 503 through the telescopic hose 502. The gas inside the horizontal tube 503 is discharged through multiple air blowing heads 504. At the same time, the output shaft of the multi-stage electric telescopic rod 505 drives the horizontal tube 503 to move up and down cyclically. As the horizontal tube 503 moves downward, it pulls the telescopic hose 502. As the horizontal tube 503 moves upward, the tension on the telescopic hose 502 is released. The horizontal tube 503 drives multiple air blowing heads 504 on it to move up and down in a cycle. During the air blowing process, the multiple air blowing heads 504 back-blowing clean the grid 201. Under the back-blowing force, the impurities located on the front side of the grid 201 and inside the mesh are blown off. The blown-off impurities fall into the counterweight collection box 301 by gravity. The counterweight collection box 301 collects the impurities. By cleaning through back-blowing, the impurities inside the mesh of the grid 201 can be effectively cleaned out, reducing the risk of grid 201 mesh blockage and improving the cleaning effect.

[0034] After a period of use, when it is necessary to clean the impurities collected inside the counterweight collection box 301, the two U-shaped handles can be pulled upwards. The two U-shaped handles, through the two limiting plates 305, pull the two pull ropes 303 upwards within their respective guide sleeves 304. The two pull ropes 303, through the two connecting blocks 302, drive the counterweight collection box 301 upwards. The counterweight collection box 301 drives the guide scraper 307 upwards. As the guide scraper 307 moves upwards, it can scrape off and clean the impurities that are not blown off from the front of the grid 201. The scraped impurities fall down the inclined surface of the guide scraper 307 into the counterweight. Inside the collection box 301, when the counterweight collection box 301 moves upward to a suitable height, the pull ring can pull the pull rod 308 to drive the slag receiving plate 306 to move upward. The slag receiving plate 306 lifts the impurities inside the counterweight collection box 301 upward, thus cleaning the impurities. At the same time as driving the counterweight collection box 301 to move upward, the guide scraper 307 is driven to scrape and clean the front side of the grid 201 again, which can further improve the cleaning effect. In addition, the method of collecting and removing the cleaned impurities can prevent the cleaned impurities from clogging the grid 201 again, thus achieving the effect of thoroughly cleaning the impurities.

[0035] After cleaning, the slag receiving plate 306 is moved back into the counterweight collection box 301, and the pull force on the U-shaped handle is released. Under the action of gravity, the counterweight collection box 301 moves downward to reset. At the same time as the counterweight collection box 301 moves downward, the two pull ropes 303 are pulled to reset, and then we can wait for the next cleaning operation.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
