DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] A self-propelled hydraulic pipeline slag cleaning device for hydraulic engineering comprises a cleaning cylinder 1, a movable seat 2 arranged at the bottom of the cleaning cylinder 1, a slag cleaning component 3 arranged inside the cleaning cylinder 1, and a storage component 4 arranged inside the cleaning cylinder 1.

[0029] In this embodiment, a plurality of driving wheels 201 are arranged on the side of the mobile seat 2, and a plurality of drivers 202 used in conjunction with the driving wheels 201 are arranged inside the mobile seat 2. The drivers 202 drive the driving wheels 201 to rotate on the side of the mobile seat 2 to realize the function of self-propelled movement. A plurality of limiting posts 203 are arranged inside the mobile seat 2, and a lifting platform 204 is arranged on the inner bottom wall of the mobile seat 2. A plurality of limiting sleeves used for sliding in conjunction with the limiting posts 203 are arranged at the bottom of the cleaning barrel 1. The limiting sleeves wrap the limiting posts 203 so that the cleaning barrel 1 can remain stable during lifting. The top of the lifting column inside the lifting platform 204 and the bottom wall of the cleaning barrel 1 are fixedly installed, so that when the lifting column of the lifting platform 204 is extended and retracted, the cleaning barrel 1 can be driven to change in height, so that the center position of the slag cleaning component 3 and the center position of the pipe wall are kept on a horizontal line, so that the slag cleaning component 3 can perfectly fit the inner wall of the pipe for cleaning.

[0030] In this embodiment, the slag cleaning component 3 includes a sliding cylinder 301 movably connected to the inside of the cleaning cylinder 1, a driving motor 302 fixedly installed on the inner wall of the sliding cylinder 301, a transmission gear 303 fixedly installed on the outer side of the output shaft of the driving motor 302, a rotating cylinder 304 rotatably connected to the inside of the sliding cylinder 301, a driving rod 305 slidably connected to the side wall of the rotating cylinder 304, an electric telescopic rod 306 fixedly installed on the side wall of the rotating cylinder 304, a limiting cylinder 307 fixedly installed on the outside of the rotating cylinder 304, a plurality of cleaning struts 308 rotatably connected to the outside of the limiting cylinder 307, a sealing plate 309 plugged and fixed to one end of the driving rod 305, an adjusting cylinder 310 fixedly installed on the outside of one end of the sealing plate 309, a plurality of adjusting struts 311 rotatably connected to the outside of the adjusting cylinder 310, a cleaning brush 312 arranged on the top of the adjusting strut 311, a plurality of cleaning nozzles 313 arranged on the outside of the cleaning cylinder 1, and a water tank 314 fixedly installed on the side wall of the cleaning cylinder 1.

[0031] An inlet and outlet 315 is provided on the side of the cleaning cylinder 1, and a sealing groove used in conjunction with the inlet and outlet 315 is provided on the side of the sliding cylinder 301. The sliding cylinder 301 is arranged on the side of the cleaning cylinder 1 for fitting, so that when cleaning is performed, the interior of the cleaning cylinder 1 is isolated to prevent cleaning residues from entering the interior of the cleaning cylinder 1 and affecting the operation of internal components. The rotating cylinder 304 transversely penetrates the front and rear side walls of the sliding cylinder 301 and is rotatably connected to the sliding cylinder 301.

[0032] A driven gear 316 is provided on the outer side of the rotating cylinder 304. The transmission gear 303 and the driven gear 316 are connected through tooth meshing transmission. By setting the meshing of the transmission gear 303 and the driven gear 316, the driving motor 302 can smoothly drive the rotating cylinder 304 to rotate. A limiting hoop 317 is provided on the outer side of the rotating cylinder 304 for use with the side wall of the sliding cylinder 301. The limiting hoop 317 is provided on the outer side of the rotating cylinder 304 so that the side wall of the sliding cylinder 301 can limit the outer side of the rotating cylinder 304 and perform synchronous lateral movement.

[0033] The driving rod 305 is a cross-shaped structure, and a cross-shaped slot is provided on the side of the rotating cylinder 304. The driving rod 305 passes through the cross-shaped slot horizontally and is slidably connected to the rotating cylinder 304, so that the rotation of the rotating cylinder 304 can drive the driving rod 305 to rotate synchronously. At the same time, the driving rod 305 can slide inside the rotating cylinder 304 to adjust the relative position of the driving rod 305 and the rotating cylinder 304.

[0034] The sealing plate 309 is a T-shaped structure, and a sealing bayonet for use with the inlet and outlet 315 is set on the side of the sealing plate 309, so that the sealing plate 309 can fill the inside of the inlet and outlet 315 when being stored, so that the inside and outside of the cleaning cylinder 1 are sealed, which can protect the components inside the device and reduce the occupied space of the device. The bottom of the cleaning brush 312 is rotatably connected to the top of the adjustment support rod 311 and the cleaning support rod 308 respectively.

[0035] It should be noted that the rotational connection between the cleaning brush 312 and the adjustment support rod 311 and the cleaning support rod 308 has a certain damping, so that the cleaning brush 312 and the inner wall of the pipeline can be kept relatively parallel, thereby improving the cleaning efficiency.

[0036] In this embodiment, the storage assembly 4 includes a storage motor 401 fixedly installed at the bottom of the sliding cylinder 301, a storage gear 402 fixedly installed on the outside of the output shaft of the storage motor 401, a storage rack 403 fixedly installed on the inner bottom wall of the cleaning cylinder 1, and a locking threaded sleeve 404 rotatably connected to the side wall of the cleaning cylinder 1.

[0037] A number of limiting slides 405 are evenly arranged on the outside of the sliding cylinder 301, and a limiting slide rail 406 used in conjunction with the limiting slide 405 is arranged on the inner wall of the cleaning cylinder 1. The limiting slide 405 is set to slide inside the limiting slide rail 406, and then the tooth pattern of the storage gear 402 is engaged with the storage rack 403 and connected through the tooth pattern transmission, so that the storage gear 402 rotates in the tooth pattern of the storage rack 403, which can drive the limiting slide 405 to move inside the limiting slide rail 406.

[0038] The telescopic rod end of the electric telescopic rod 306 and the side of the driving rod 305 are fixedly installed, so that the length change of the electric telescopic rod 306 can push the driving rod 305 to move inside the rotating cylinder 304, and the outer side of one end of the electric telescopic rod 306 located outside the rotating cylinder 304 is provided with a thread pattern for use with the locking threaded sleeve 404, so that when storing, the locking threaded sleeve 404 can synchronously lock the electric telescopic rod 306 and the rotating cylinder 304.

[0039] The working principle of the above embodiment is:

[0040] By controlling the electric telescopic rod 306 to extend, the extension of the electric telescopic rod 306 pushes the driving rod 305 to move laterally in the rotating cylinder 304, and pushes the sealing plate 309 to move laterally, so that a certain angle is formed between the adjustment support rod 311 and the cleaning support rod 308, and the cleaning brush 312 is pushed toward the inner wall of the pipeline, and the lifting platform 204 is controlled to lift and lower to drive the height of the cleaning cylinder 1 to change, and the height change of the cleaning cylinder 1 drives the height change of the sliding cylinder 301, so that the driving rod 305 is located at the center line position of the pipeline, so that the cleaning brush 312 is respectively close to the inner wall of the pipeline, and the driving motor 302 is started to drive the rotating cylinder 304 to rotate, and the rotation of the rotating cylinder 304 drives the driving rod 305 and the cleaning brush 312 to clean the inner wall of the pipeline.

[0041] In addition, the inside of the water tank 314 is sprayed on the inner wall of the pipe through the cleaning nozzle 313 to improve the cleaning effect of the cleaning brush 312. After the cleaning is completed, the electric telescopic rod 306 is controlled to extend, and the electric telescopic rod 306 pushes the driving rod 305 to move. The movement of the driving rod 305 drives the sealing plate 309 to move, thereby driving the adjusting support rod 311 and the cleaning support rod 308 to form a straight line. The storage motor 401 is controlled to rotate, and the storage motor 401 drives the storage gear 402 to rotate on the outside of the storage rack 403, thereby driving the sliding cylinder 301 to move. The movement of the sliding cylinder 301 retracts the driving rod 305 and the rotating cylinder 304 into the interior of the cleaning cylinder 1, and the sealing plate 309 is filled and sealed on the side of the cleaning cylinder 1 to complete the storage, thereby solving the problems of poor cleaning effect and inconvenient storage of the slag cleaning device for the water conservancy pipeline.

[0042] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and they can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the control method and circuit connection are no longer explained in detail in this embodiment.
