Description

Technical Field

[0001] This invention relates to the field of water surface cleaning technology, specifically to a self-rotating dam slag removal machine. Background Technology

[0002] As a crucial component of water conservancy projects, dams often accumulate large amounts of floating debris, such as branches, leaves, plastic waste, and algae, in their upstream waters due to water flow, wind action, or human activities. This debris not only affects the aquatic landscape but can also clog critical facilities like spillways and intakes, impacting dam operation safety and hydropower station efficiency. Therefore, regular cleaning of the debris in the waters upstream of dams is of paramount importance.

[0003] Traditional methods of dam slag removal mainly rely on manual labor or fixed cleaning equipment. Manual labor removal is inefficient, labor-intensive, and poses safety hazards, making it unsuitable for large-scale, high-frequency cleaning needs. Existing mechanical slag removal equipment is prone to clogging during slag transport and lacks effective slag collection and drainage structures, affecting the equipment's continuous operation capacity and cleaning effectiveness. Furthermore, existing mechanical equipment is mostly fixed in structure, limiting its cleaning range and preventing flexible adjustment of its working position according to slag distribution, resulting in incomplete cleaning and blind spots. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides the following technical solution: a self-rotating dam slag removal machine, comprising: The support portion includes a support frame; The conveying unit is mounted on the support frame and includes a conveying support frame fixedly mounted on the support frame. A conveyor belt for conveying scum is mounted on the conveying support frame. The conveyor belt is mounted on the conveying support frame via a first conveying roller, a second conveying roller, a limit roller, and a third conveying roller. The third conveying roller is rotatably mounted on a conveying adjusting slider, which is slidably mounted in a groove on a fixed conveying frame. A conveying adjusting screw is threaded onto one side of the conveying adjusting slider and is rotatably mounted on the fixed conveying frame. The collection unit includes a collection shell, which is mounted on a conveying support frame. The collection shell has a hollow interior and a collection cover for water intake is provided on the top of the collection shell. The side wall of the collection shell is connected to the water inlet end of the collection pump, and the water outlet end of the collection pump is connected to a collection drain pipe. The two ends of the collection drain pipe are respectively fixed with collection drain cylinder two and collection drain cylinder one.

[0005] Furthermore, the first conveyor roller is fixedly mounted on the output shaft of the conveyor belt drive motor, the conveyor belt drive motor is fixedly mounted on the side wall of the conveyor support frame, and the first conveyor roller, the conveyor limiting roller, the second conveyor roller, and the third conveyor roller all have frictional contact with the conveyor belt.

[0006] Furthermore, the conveyor belt is provided with several through holes, and the outer surface of the conveyor belt is provided with multiple baffles for removing scum.

[0007] Furthermore, a discharge port is provided on the inclined bottom surface of the conveyor support frame, and a conveyor discharge plate is provided on the discharge port to receive the scum falling from the conveyor belt.

[0008] Furthermore, a support collection box is provided below the conveyor discharge plate, and the support collection box is detachably mounted on the support frame via a sliding groove.

[0009] Furthermore, a support worm gear is fixedly installed at the bottom of the support frame. The support worm gear is rotatably mounted on the support rod. The support worm gear meshes with the support worm. The support worm is rotatably mounted on the support rod. The support worm is fixedly mounted on the output shaft of the support adjustment motor.

[0010] Furthermore, the bottom of the support collection box is provided with a water filter hole, which is used to filter out the water from the scum.

[0011] The advantages of this invention compared to the prior art are: 1. Stable conveying and excellent anti-clogging performance: The conveyor section is equipped with a tensioning mechanism consisting of a conveyor adjusting slider and a conveyor adjusting screw, which can adjust the tension of the conveyor belt at any time to ensure smooth and non-slipping operation. Simultaneously, the conveyor belt is equipped with through holes and baffle structures. The through holes can filter out some moisture, and the baffles can effectively remove floating scum, preventing it from slipping or clogging during conveying and improving conveying efficiency.

[0012] 2. Integrated drainage and collection for improved efficiency: The collection section employs a pumping and circulating structure. A pump draws water containing scum into the collection casing, and the water is then discharged back into the water body through the collection drain pipe. The scum remains inside the collection casing and is carried away by a conveyor belt. This design achieves scum-water separation, preventing scum from accumulating at the collection port. Additionally, the bottom of the supporting collection box has filter holes to further drain water from the scum, reducing its weight and facilitating subsequent transportation and processing.

[0013] 3. Wide cleaning range with no blind spots: Through the worm gear transmission mechanism in the support section, the entire slag removal machine can rotate freely, driving the collection hood to operate at different positions on the water surface. This solves the problem of limited cleaning range and blind spots inherent in fixed slag removal equipment, allowing for flexible adjustment of the working position according to the distribution of slag, achieving comprehensive cleaning of the water area in front of the dam.

[0014] 4. High degree of automation, reducing labor costs: The equipment is driven by a motor to achieve automatic rotation, automatic conveying and automatic collection, which greatly reduces the labor intensity and safety risks of manual slag removal. It realizes the fully automated operation from slag collection and conveying to packing, and adapts to the needs of high-frequency and large-scale slag removal. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 7 As shown, a self-rotating dam slag removal machine includes a conveying unit 1, a collecting unit 2, and a supporting unit 3.

[0025] like Figures 1 to 7 As shown, the support unit 3 includes a support rod 301, a support adjusting motor 302, a support worm gear 303, a support worm wheel 304, a support frame 305, and a support collection box 306. The support worm wheel 304 is fixedly mounted on the bottom of the support frame 305 and rotatably mounted on the support rod 301. The support rod 301 has mounting holes at its bottom. The support worm wheel 304 meshes with the support worm gear 303, which is rotatably mounted on the support rod 301. The support worm gear 303 is fixedly mounted on the output shaft of the support adjusting motor 302. The support collection box 306 is located below the conveyor discharge plate 102. The support collection box 306 has a rectangular structure and is detachably connected to the guide rail on the support frame 305 via a sliding groove at its bottom. The support collection box 306 has filter holes at its bottom for filtering water from the scum.

[0026] like Figures 1 to 7As shown, the conveying unit 1 is mounted on the support frame 305. The conveying unit 1 includes a conveying support frame 101, a conveying discharge plate 102, a first conveying roller 103, a conveyor belt 104, a conveying limiting roller 105, a second conveying roller 106, a third conveying roller 107, a conveying adjusting slider 108, a conveying adjusting screw 109, a conveying fixing frame 110, and a conveyor belt drive motor 111. The conveying support frame 101 is fixedly mounted on the support frame 305. A conveyor belt 104 for conveying scum is mounted on the conveying support frame 101. The conveyor belt 104 passes through the first conveying roller 103, the second conveying roller 106, the third conveying roller 105, and the conveying discharge plate 102. Roller 3 107 is mounted on the conveyor support frame 101. Roller 3 107 is rotatably mounted on the conveyor adjusting slider 108, which is slidably mounted in a groove on the conveyor fixing frame 110. A conveyor adjusting screw 109 is threaded onto one side of the slider 108 and rotatably mounted on the conveyor fixing frame 110. Tightening the screw causes the slider 108 and roller 3 107 to move within the conveyor fixing frame 110, thereby adjusting the position of roller 3 107 and tensioning the conveyor belt 104. Roller 1 103 is fixedly mounted on the output shaft of the conveyor belt drive motor 111, which is fixedly mounted on the side wall of the conveyor support frame 101. Roller 1 103, conveyor limiting roller 105, roller 2 106, and roller 3 107 all engage with the conveyor belt 104 through friction. The conveyor belt 104 has several through holes, and its outer surface is equipped with multiple baffles for removing scum. A discharge port is located on the inclined bottom surface of the conveyor support frame 101, and a conveyor discharge plate 102 is installed on the discharge port to collect scum falling from the conveyor belt 104. A support collection box 306 is located below the conveyor discharge plate 102, and the support collection box 306 is detachably mounted on the support frame 305 via a sliding groove.

[0027] like Figures 1 to 7 As shown, the collection unit 2 includes a collection housing 201, a collection pump 202, a collection drain pipe 203, a first collection drain cylinder 204, a second collection drain cylinder 205, and a collection cover 206. The collection housing 201 is mounted on the conveying support frame 101. The inside of the collection housing 201 is a hollow structure. The top of the collection housing 201 is provided with a collection cover 206 for water inlet. The side wall of the collection housing 201 is connected to the water inlet end of the collection pump 202. A filter screen is provided between the collection housing 201 and the collection pump 202. The drain end of the collection pump 202 is connected to the collection drain pipe 203. The two ends of the collection drain pipe 203 are respectively fixedly provided with the second collection drain cylinder 205 and the first collection drain cylinder 204.

[0028] like Figures 1 to 7As shown, the present invention discloses a self-rotating dam slag removal machine. Its working principle is as follows: The device is installed in a suitable position through the mounting hole at the bottom of the support rod 301, so that the collection cover 206 extends 5 cm below the water surface. The collection pump 202 is turned on, drawing water containing slag from the collection cover 206 into the collection shell 201. The water is then discharged again from the side wall of the collection shell 201 through the collection drain pipe 203, the second collection drain cylinder 205, and the first collection drain cylinder 204. The slag then enters the collection shell 201. Afterwards, the conveyor belt drive motor 111 is turned on. The conveyor belt drive motor 111 rotates, which drives the conveyor roller 103 to rotate. The rotation of the conveyor roller 103 drives the conveyor belt 104 to rotate. The rotation of the conveyor belt 104 gradually transports the scum in the collection shell 201 to the conveyor discharge plate 102. The scum transported to the conveyor discharge plate 102 falls onto the conveyor discharge plate 102 under the action of gravity. Similarly, under the action of gravity, the scum slides from the conveyor discharge plate 102 into the support collection box 306 and is collected.

[0029] When the entire device needs to be rotated, the support adjustment motor 302 is started. The rotation of the support adjustment motor 302 drives the support worm gear 303 to rotate, which in turn drives the support worm wheel 304, thereby causing the entire device to rotate around the support rod 301 to a predetermined position. This changes the position of the collection hood 206 in the water, allowing for the collection of scum from different locations. Once a certain amount of scum has been collected in the support collection box 306, the support collection box 306 can be removed from the support frame 305 for cleaning.
