[0001] The invention relates to the technical field of hoses, in particular to a fracture-proof hydraulic engineering dredging hose. Background Art

[0002] Water conservancy projects can meet the demand for water resources in people's lives and production by regulating and distributing water volume. Their purpose is achieved by building various water conservancy projects such as dams, river banks, spillways, and channels. When water conservancy projects are constructed, many pipes are generally used to transport and discharge water. However, when using pipes, silt will accumulate at the bends and connections of the two pipes due to long-term use. If the silt is not cleaned, the pipes will be blocked.

[0003] Currently, the most common pipes are metal pipes fixed with bolts. The pipes need to be disassembled during dredging, which affects the water flow. Rubber hoses can also be used as connecting pipes. Because of their own softness, the hoses can be used to connect pipes at different positions and angles. Compared with special metal pipes, they are more applicable. However, because of their softness, the hoses are easily squeezed and bent after collisions, which may lead to problems such as the hoses breaking easily or the passage being blocked.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention can prevent the dispersed sludge from being directly sent out through the outlet end through the interception of the sieve plate. Under the action of the cleaning component, the sludge is dispersed and enters between the outer wall of the inner tank and the annular filter through the outlet of the inner tank. At this time, one end of the sieve plate can continue to deliver water, and the sludge and clean water are separated through the annular filter.

The plug plate of the rotating frame moves along the moving groove to intermittently open and close the outlet of the inner tank, and the rotation direction of the rotating frame is opposite to that of the inner tank. The sludge entering the inner tank is stirred and dispersed by the stirring frame on the vertical plate to facilitate the flow into the annular filter. When the inner tank rotates, it will drive the rotation of the rubber scraper. The other end of the rubber scraper slides along the slide rail to scrape and clean the inner wall of the hose body, and clean the sludge attached to the inner wall.

[0018] 3. The protective layer and steel wire of the hose body in the present invention can enhance the strength of the hose body itself, and cooperate with the storage ring and the limit rope at the outer end. According to the bending shape of the hose body after installation, the limit ropes at different positions are released to different lengths along the perforations of the storage ring and kept in contact with the surface of the hose body. Then, the adjusting bolt is rotated to squeeze and fix the limit ropes in the receiving grooves of all the storage rings through the pressure ring. The limit ropes are tightened to protect the periphery of the hose body and have a certain shaping effect, thereby preventing the hose body from deformation and improving the anti-fracture strength of the hose body.

[0019] 4. Compared with the prior art, the hose body of the present invention can be suitable for pipe connections at different angles and positions. The protective component is used to shape the installed hose body to prevent it from breaking. The cleaning component in the dredging barrel is used to clean the silt accumulated in the hose body and send it into the annular filter after the silt is dispersed in the inner tank, which does not affect the normal transportation of the water flow. At the same time, it can play the role of cleaning the inside of the hose body without disassembling it. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In this embodiment, the cleaning component 6 also includes a moving groove 612, the inner liner 61 is provided with a moving groove 612, the rotating frame 62 includes a ring and a plug plate, the plug plate of the rotating frame 62 is slidably inserted into the moving groove 612, and the ring of the rotating frame 62 has the same inner diameter as the inner liner 61, a vertical plate 63 is fixed inside the ring of the rotating frame 62, and one end of the stirring frame 64 is fixed at the center of the vertical plate 63, and two ends of the outer surface of the inner liner 61 are symmetrically rotatably sleeved with two sealing plates 65, and the outer sides of the two sealing plates 65 are provided with toothed rings 66, and the two sealing plates 65 are provided with toothed rings 66. The gear rings 66 are respectively sleeved on the surfaces of the inner liner 61 and the rotating frame 62 rings, and the tops of the two gear rings 66 are provided with driving gears 68. The gear rings 66 on the surface of the inner liner 61 are meshed and connected with the top driving gears 68, and a small motor 69 is fixed to the position of the inner wall of the dredging cylinder 3 corresponding to the driving gear 68, and the output end of the small motor 69 is fixedly connected to the driving gear 68. The top of the gear ring 66 of the rotating frame 62 ring is meshed and connected with a transmission gear 67, and the transmission gear 67 is rotatably installed on the surface of the sealing plate 65 through a bearing. The other side of the gear 67 is meshed with the driving gear 68, and a shaft 611 is fixed between the two driving gears 68. A waterproof package is arranged on the periphery of the small motor 69. The small motor 69 drives the two driving gears 68 to rotate at the same time through the shaft 611. The driving gear 68 on one side is meshed with the gear ring 66 on the inner liner 61 to drive the inner liner 61 to rotate, and the driving gear 68 on the other side is meshed with the transmission gear 67, and then meshed with the gear ring 66 on the ring of the rotating frame 62 through the transmission gear 67, so as to drive the rotating frame 62 to rotate. The plug plate moves along the moving groove 612, intermittently opening and closing the outlet of the inner tank 61, and the rotating frame 62 rotates in the opposite direction to the inner tank 61. The sludge entering the inner tank 61 is stirred by the stirring frame 64 on the vertical plate 63 to facilitate the flow into the annular filter 7.

Under the action of the cleaning component 6, the sludge is stirred and then enters between the outer wall of the inner tank 61 and the annular filter screen 7 through the outlet of the inner tank 61. At this time, one end of the sieve plate 33 can continue to deliver water, and the sludge and clean water are separated through the annular filter screen 7. The clean water enters the inside of the connecting layer 41 from the water outlet 32 ​​and is also sent out from the water outlet 4, so as to avoid affecting the transportation of the water flow and at the same time, it will not cause the overflow of the water flow during the dredging process.

[0034] When using the device, one end of the hose body 1 is connected to the upstream pipeline, and the outlet end is connected to the downstream pipeline through the flange 5. The protective layer 11 and the steel wire of the hose body 1 can strengthen the strength of the hose body 1 itself. In conjunction with the receiving ring 21 and the limiting rope 24 at the outer end, according to the bending shape of the hose body 1 after installation, the limiting rope 24 at different positions is released along the perforation of the receiving ring 21 to different lengths and keep in contact with the surface of the hose body 1. Then, the adjusting bolt 22 is turned to squeeze and fix the limiting rope 24 in the receiving groove of all the receiving rings 21 through the pressing ring 23. 24 is tightened to protect the periphery of the hose body 1 and to play a certain shaping effect, thereby preventing the hose body 1 from being deformed and improving the anti-fracture strength of the hose body 1. When the hose body 1 is blocked, the small motor 69 drives the two driving gears 68 to rotate through the shaft 611 at the same time. The driving gear 68 on one side is meshed and connected with the toothed ring 66 on the inner liner 61 to drive the inner liner 61 to rotate, and the driving gear 68 on the other side is meshed and connected with the transmission gear 67, and then meshed and connected with the toothed ring 66 on the ring of the rotating frame 62 through the transmission gear 67 to drive the rotating frame 62 to rotate. The plug plate of the rotating frame 62 moves along the moving groove 612, intermittently opening and closing the outlet of the inner tank 61, and the rotating direction of the rotating frame 62 is opposite to that of the inner tank 61. The sludge entering the inner tank 61 is stirred and dispersed by the stirring frame 64 on the vertical plate 63 to facilitate the flow into the annular filter screen 7. When the inner tank 61 rotates, it will drive the rotation of the rubber scraper 13. The other end of the rubber scraper 13 slides along the slide rail 12 to scrape and clean the inner wall of the hose body 1, and clean the sludge attached to the inner wall. The interception of the screen plate 33 can prevent the stirred sludge from being directly sent to the outlet end. Out, under the action of the cleaning component 6, the sludge is dispersed and enters between the outer wall of the inner liner 61 and the annular filter 7 through the outlet of the inner liner 61. At this time, one end of the sieve plate 33 can continue to deliver water, and the sludge and clean water are separated through the annular filter 7. The clean water enters the inside of the connecting layer 41 from the water outlet 32 ​​and is also delivered from the water outlet end 4 to avoid affecting the transportation of the water flow. At the same time, it will not cause water overflow during the dredging process. By manually opening the top cover 31 regularly and removing the upper layer of the annular filter 7, the internal sludge can be directly cleaned without dismantling the pipeline for dredging.
