Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically to a cleaning equipment that integrates a cleaning gate body. Background Technology

[0002] A trash rack, also known as a trash racking machine, is a mechanical device used to remove debris attached to a trash rack. It is often installed in reservoirs or rivers with a lot of dirt so that trash can be removed without shutting down the machine or emptying the reservoir, ensuring the safe and normal operation of hydropower stations or pumping stations.

[0003] When used for a long time, restarted after maintenance, or when a large amount of debris accumulates in front of the trash rack, the rake cannot clean it in time, leading to debris buildup. This causes excessive pressure on the transmission parts when the rake is running, and may even cause the main shaft or chain to break. To solve this problem, existing technologies use a separate cleaning claw to grab and remove the debris accumulated in front of the rack. This requires space in front of the dam to install the cleaning claw, which may not be available in small rivers or reservoirs. Furthermore, installing a separate cleaning claw increases the cleaning cost. Utility Model Content

[0004] One advantage of this utility model is that it provides an integrated cleaning device for the gate body. The integrated cleaning device is set up with the gate body, which can not only remove the dirt in front of the gate body, but also reduce the cleaning cost, save installation space, and can be installed on small dam bodies, making it more adaptable.

Mounting sleeves 2 are fixedly installed on both sides of the screen body 1. The three-stage hydraulic cylinders 5 are installed inside the mounting sleeves 2. When the three-stage hydraulic cylinders 5 are fully extended, the horizontal height of the cleaning rake 7 exceeds the horizontal height of the cleaning component.

The upper surface of the cleaning rake 7 is below the liquid surface; the toothed rake 3 structure includes a motor 11 fixedly mounted on the upper part of the grid body 1, the motor 11 is connected to a transmission belt and a gear 12 is connected through the transmission belt, the gear 12 is meshed with a chain 4, and several toothed rakes 3 are fixedly mounted on the chain 4. The motor 11 drives several toothed rakes 3 to reciprocate around the grid body 1 through the chain 4, lifting the dirt in front of the grid body 1 and dumping it onto the transmission assembly; the transmission assembly includes a mounting platform 14, on which a conveyor belt 13 is mounted; the cleaning rake 7 includes several parallel second rake teeth horizontally fixedly mounted on both sides of the crossbar 6, and the toothed rake 3 includes a rake rod and first rake teeth fixedly mounted on the rake rod.

[0019] The first embodiment of this utility model is as follows:

[0020] An integrated sewage cleaning device for a dam includes a transmission component installed on the upper part of the dam body and a sewage cleaning component installed at the waterway of the dam body. The sewage cleaning component blocks sewage on the river or reservoir and lifts it. When the rake 3 passes over the top of the gate body 1, the sewage falls onto the transmission component and is transferred and collected. The transmission component includes a mounting platform 14, on which a conveyor belt 13 is installed to transfer the sewage to a sewage collection box.

[0021] The cleaning component includes a screen 1, which includes a frame and multiple steel bars arranged vertically and parallel to each other in the lower part of the frame. There are gaps between the steel bars to allow water to flow through while trapping dirt. The screen 1 is equipped with a toothed rake 3 structure that reciprocates in a circular motion. The toothed rake 3 structure includes a motor 11 fixedly mounted on the upper part of the screen 1. The motor 11 is connected to a transmission belt, which in turn is connected to a gear 12. There are two gears 12, located on both sides of the screen 1 and connected in the middle by a coupling. The gears 12 are meshed with a chain 4. Several toothed rakes 3 are fixedly mounted on the chain 4. Each toothed rake 3 includes a rake rod and a first rake tooth fixedly mounted on the rake rod. The two ends of the rake rod are connected to two chains 4. The motor 11 drives the several toothed rakes 3 to reciprocate around the screen 1 through the chain 4.

[0022] When used for a long time, restarted after shutdown for maintenance, or when a large amount of dirt accumulates in front of the trash rack 1, the rake 3 cannot clean it in time, leading to dirt buildup. This causes excessive pressure on the transmission parts when the rake 3 is running, and may even cause the main shaft or chain 4 to break. To solve this problem, this application has a lifting structure fixedly installed on the rack 1. Since there is a lot of dirt accumulated, forcibly lifting it will cause the main shaft or chain 4 to break. Therefore, a lifting structure with a higher load capacity is set up to lift the dirt and reduce the load pressure on the cleaning components.

[0023] The lifting structure includes mounting sleeves 2 fixedly installed on both sides of the frame of the grid body 1. The midpoint of the mounting sleeve 2 is on the same plane as the liquid surface. A three-stage hydraulic cylinder 5 is installed inside the mounting sleeve 2. The installation of the three-stage hydraulic cylinder 5 extends the lifting height of the hydraulic cylinder. After the three-stage hydraulic cylinder 5 is fully extended, the horizontal height of the cleaning rake 7 exceeds the horizontal height of the cleaning component, which facilitates cleaning. This ensures that the three-stage hydraulic cylinder 5 does not come into contact with water, preventing the hydraulic cylinder from failing or rusting. At the same time, it can also reduce the height of the three-stage hydraulic cylinder 5. The upper surface of the cleaning rake 7 is below the liquid surface, which facilitates the lifting of dirt. A horizontally set connecting rod 10 is fixedly connected to the top of the three-stage hydraulic cylinder 5. An extension rod 9 is fixedly connected to the other end of the connecting rod 10. The two ends of the crossbar 6 are connected to the lower end of the extension rod 9. The cleaning rake 7 is horizontally set on the crossbar 6.

[0024] A reinforcing bar 8 is also inclined between the crossbar and the extension bar to improve the structural strength.

[0025] The horizontal extension length of the first rake tooth is less than the horizontal distance between the crossbar 6 and the rake rod, ensuring that the cleaning rake 7 will not hit the rake rod during the lifting process and preventing interference. The cleaning rake 7 includes several parallel second rake teeth that are horizontally fixed on both sides of the crossbar 6. The first and second rake teeth facing the rake 3 are staggered and will not interfere with each other during relative movement, ensuring smooth movement of the cleaning rake 7.

[0026] Meanwhile, the distance between the first rake tooth and the grid body 1 is only slightly larger than the diameter of the rake rod. For the accumulated dirt, this distance will not affect the collection and lifting of dirt by the cleaning rake 7. It can lift and collect the vast majority of dirt, and has achieved the effect of collecting a large amount of dirt and reducing the load pressure on the motor 11. The remaining dirt is relatively small and can be lifted and collected by the toothed rake 3.

[0027] The technical solution described in this application is mainly applied to small-scale cleaning machines. After the cleaning rake 7 lifts a large amount of dirt, it can be cleaned manually. Alternatively, after the cleaning rake 7 lifts part of the dirt, the remaining dirt can be lifted and collected by the toothed rake 3. Then, the cleaning rake 7 is lowered, and the toothed rake 3 collects this part of the dirt, dividing the original batch of dirt into two parts for collection in batches. This also helps to reduce the load pressure on the motor 11. Therefore, the technical solution described in this application can be used in various ways according to actual needs, and all of them can achieve the technical effect that this application aims to achieve.

[0028] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
