Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a device for desilting a water channel for water conservancy and hydropower construction. Background Art

[0002] Water conservancy and hydropower projects are widely used in daily life, especially water conservancy canals are widely used in agricultural irrigation. During the long-term use of canals, a large amount of silt and debris will be deposited inside the channels, which will affect the flow of water. At the same time, a large amount of silt will be brought into the farmland, affecting the growth of crops. In order to ensure the water flow of the canals, the canals need to be dredged. When dredging the canals, there is some sewage in the canals, which can facilitate the extraction of silt and improve the fluidity of silt.

[0003] The existing canal dredging is mainly carried out by moving a shovel pushed by a mobile vehicle, which can quickly clean the silt inside the canal, extract the silt inside the shovel through a sludge pump, and discharge the silt through a sewage pipe. However, the silt in the canal contains hard objects such as gravel or stones. Since some of the gravel or stones in the silt are large, the gravel or stones will cause damage to the inside of the sewage pipe when they enter the sewage pipe. After the pipe is damaged, it needs to be replaced, which affects the efficiency of the dredging work.

[0004] The Chinese patent with the authorization announcement number CN116397710A discloses a canal desilting device for water conservancy and hydropower construction, including a desilting mechanism for cleaning and collecting silt in the canal; a moving mechanism for driving the desilting mechanism to move in the canal; and a crushing mechanism connected to the desilting mechanism for crushing the silt entering the desilting mechanism. By setting up the moving mechanism, it is convenient to drive the desilting mechanism to move in the canal, and by setting up the crushing mechanism, the silt extracted by the desilting mechanism can be crushed, thereby avoiding the situation where the desilting pipeline is blocked by large stones or rocks in the silt, reducing the damage to the pipeline and improving the efficiency of the desilting work.

[0005] However, the above patent still has the following disadvantages: 1. According to the description of the above patent, the above patent directly crushes stones to avoid stones blocking the dredging pipe. However, in actual use, the stones are hard to be effectively crushed and are easy to jam the dredging device. In addition, the sludge in the canal is often mixed with plant fibers that have not yet rotted and decomposed. The tough plant fibers are easy to be entangled in the crushing mechanism of the above patent, which will also affect the normal operation of the dredging device.

[0006] 2. In actual use, the sludge is relatively viscous, with poor fluidity, and is mixed with various impurities, making it difficult for the sludge to flow and transport, affecting the collection effect of the sludge, and ultimately causing the sludge to accumulate in the device and be difficult to handle. Summary of the invention

The sludge and sewage can be centrifugally separated to facilitate subsequent separate treatments, and the water in the sewage barrel is re-introduced by a water pump and sprayed into the sludge squeezed in the silt cleaning bucket, which plays a role in diluting the sludge, making it easier for small particles in the sludge to pass through the spring, thereby improving the filtering efficiency of the sludge.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1-7 As shown, a dredging device for water channels used in water conservancy and hydropower construction includes a vehicle body 10, a dredging bucket 11 is fixedly connected to the bottom side of the vehicle body 10, a plurality of filter slots 17 are evenly distributed on the arc-shaped side wall of the dredging bucket 11, a sewage collecting bin 35 is fixedly connected to the bottom side of the vehicle body 10, and the opening of the sewage collecting bin 35 is tightly abutted against the arc-shaped side wall of the dredging bucket 11, a rotating shaft 19 is rotatably connected in the dredging bucket 11, a rotating wheel 12 eccentrically arranged with the dredging bucket 11 is fixedly connected to the rotating shaft 19, a plurality of chute 13 are evenly distributed in the rotating wheel 12 in the circumferential direction, a scraper 14 is slidably connected in each chute 13, a group of springs 18 are connected between each scraper 14 and the bottom of the chute 13, and a scraper bar 15 is embedded and connected to the end of each scraper 14 extending out of the chute 13, and each scraper bar 15 can fit closely with the inner wall of the dredging bucket 11 and slide relatively.

[0029] By setting a rotating wheel 12 eccentric to the silt cleaning bucket 11, the sludge at the bottom of the canal is continuously shoveled into the silt cleaning bucket 11 while the rotating wheel 12 drives the scraper 14 to rotate, and the sludge is squeezed so that the flowable substances in the sludge pass through the filter tank 17, and the larger stones and plant fibers in the sludge are intercepted to prevent them from clogging the collection components and causing device failure.

[0030] like Figure 1-7 As shown, a sewage barrel 25 is fixedly connected to one end of the bottom side of the vehicle body 10 away from the dredging bucket 11, a barrel rack 29 fixedly connected to the outer side of the sewage barrel 25 is fixedly connected to a barrel rack 29 fixedly connected to the sewage collecting bin 35, a sewage valve 41 is fixedly connected to the bottom side of the outer wall of the sewage barrel 25, a sewage pump 55 is fixedly connected to the bottom of the sewage collecting bin 35 away from the dredging bucket 11, a sewage pipe 54 is fixedly connected above the sewage pump 55, one end of the sewage pipe 54 away from the sewage pump 55 penetrates into the side wall of the sewage barrel 25 near the vehicle body 10, two water pumps 26 are symmetrically distributed and fixedly connected at the bottom of the outer wall of the sewage barrel 25, each water pump 26 is fixedly connected to a water pipe 27 at the bottom, each water pipe 27 is connected to a one-way valve 28 at one end away from the water pump 26, and each one-way valve 28 is connected to the inside of the dredging bucket 11.

[0031] By setting up a sewage pump 55, the sludge that has been initially filtered by the dredging bucket 11 can be transported to the sewage tank 25 for storage, and the water in the sewage tank 25 is re-introduced by the water pump 26 and sprayed into the sludge squeezed in the dredging bucket 11, which plays a role in diluting the sludge, making it easier for small particles in the sludge to pass through the spring 18, thereby improving the filtering efficiency of the sludge.

[0032] like Figure 1-7As shown, a raised frame 30 is fixedly connected to the bottom side of the sewage barrel 25, and a centrifugal barrel 31 coaxial with the sewage barrel 25 is rotatably connected inside the raised frame 30. A plurality of groups of through grooves 32 are evenly distributed on the barrel wall of the centrifugal barrel 31, and a filter screen 33 with fine mesh is attached to the inner wall of the centrifugal barrel 31. The sewage pipe 54 extends into the end of the sewage barrel 25 and extends to the top opening of the centrifugal barrel 31. A barrel cover 39 is threadedly connected at a corresponding position of the sewage barrel 25 in the vehicle body 10, and a transmission shaft 37 is rotatably connected inside the barrel cover 39. A locking plate 36 is fixedly connected to the bottom of the transmission shaft 37, and two locking grooves 34 are symmetrically distributed at the top of the outer wall of the centrifugal barrel 31, and the two ends of the locking plate 36 can be respectively engaged with the two locking grooves 34.

[0033] By providing a rotatable centrifugal drum 31, the sludge-mixed sewage that has been preliminarily filtered first enters the centrifugal drum 31, and the sewage is filtered out of the sludge under the rotation and centrifugation of the centrifugal drum 31, thereby separating the new sewage from the sludge, facilitating subsequent separate treatments, and ensuring that the water pump 26 stably injects sludge-free water into the dredging bucket 11 to dilute the sludge.

[0034] like Figure 1-7 As shown, a group of cleaning needles 16 are fixedly connected to the outer wall of the wheel 12 at one side of each scraper 14, and each cleaning needle 16 can extend into the corresponding filter slot 17. A suction sleeve 42 connected to the interior of the silt cleaning bucket 11 is fixedly connected above the silt cleaning bucket 11 in the vehicle body 10, and a collecting box 44 is fixedly connected to one side of the suction sleeve 42 above the vehicle body 10. An air duct 43 is connected between the collecting box 44 and the suction sleeve 42, and a fan 45 is fixedly connected to the side of the collecting box 44 away from the air duct 43. A box cover 46 is fixedly connected to the top of the collecting box 44, and a filter element 47 that fits the inner wall of the collecting box 44 is fixedly connected to the bottom side of the box cover 46.

[0035] By providing a cleaning needle 16, the filter tank 17 can be cleaned after the impeller 12 rotates and squeezes the sludge, thereby preventing stones or plant fibers from clogging the filter tank 17 and affecting the subsequent filtering efficiency. The suction force generated by the fan 45 can be used to suck the stones and plant fibers scraped away by the cleaning needle 16 into the collection box 44 for storage, thereby ensuring the dredging effect.

[0036] like Figure 1-7As shown, a third motor 38 is fixedly connected to the barrel cover 39, and a power output end of the third motor 38 is transmission-connected to the transmission shaft 37; second wheel frames 51 are fixedly connected to the four corners of the vehicle body 10, and a second motor 52 is fixedly connected to the inner side of each second wheel frame 51, and a power output end of each second motor 52 passes through the second wheel frame 51 and is transmission-connected to a walking wheel 53; a first wheel frame 23 is fixedly connected to an edge of one side of the vehicle body 10, and a first motor 24 is fixedly connected to one side of the first wheel frame 23, and a power output end of the first motor 24 passes through the first wheel frame 23 and is transmission-connected to a driving wheel 21; one end of the rotating shaft 19 extending out of the dredging bucket 11 is fixedly connected to a driven wheel 20, and a transmission belt 22 is transmission-connected between the driven wheel 20 and the driving wheel 21; a battery compartment 48 is fixedly connected to the surface of the vehicle body 10, and a high-density battery 49 is installed in the battery compartment 48; a sealing cover 50 is detachably connected to the top opening of the battery compartment 48, and the sealing cover 50 can wrap the top opening edge of the battery compartment 48.

[0037] By providing a high-density battery 49, the power consumption of various electrical equipment of the device can be met to drive the device to operate, and by providing walking wheels 53, the device can be overlapped on the edge of the canal for movement to achieve automatic silt removal, and by providing a sealing cover 50, a better sealing effect can be provided to avoid short-circuit failure of the high-density battery 49 in a humid environment.

[0038] In this embodiment, initially, the operator electrically connects various electrical components in the device to the high-density battery 49, and connects the device to the control system. The operator uses a lifting device to lift the device to the canal, and extends the main body of the device into the canal, and each walking wheel 53 overlaps the edge of the canal. At this time, the sewage valve 41 is in a closed state, and the locking plate 36 is inserted into the locking groove 34 so that the transmission shaft 37 can drive the centrifugal barrel 31 to rotate.

[0039] Then, the operator starts the second motor 52 to drive the running wheel 53 to rotate, so that the device moves along the canal by itself, and starts the first motor 24 at the same time, and drives the rotating wheel 12 to drive the scraper 14 to rotate through the transmission of the driving wheel 21 and the driven wheel 20. The scraper 14 continuously shovels the sludge at the bottom of the canal into the silt removal bucket 11. In this process, the sludge is mixed with sewage, large particles of stones and undecayed plant fibers. If it is not processed, it will block the collection component, causing the sludge to accumulate inside the device and be difficult to process.

[0040] Due to the eccentric setting of the impeller 12 and the silt cleaning bucket 11, the scraper 14 will slide against the inner wall of the silt cleaning bucket 11 and compress the spring 18 to retract into the chute 13 during the continued rotation, so that the space between the impeller 12 and the silt cleaning bucket 11 is reduced to squeeze the sludge, so that small particles with good fluidity in the sludge and sewage pass through the filter tank 17 into the sewage collecting bin 35, while large particles of stone and plant fibers are retained by the filter tank 17, avoiding clogging of the collecting components by large particles.

[0041] At the same time, the control system starts the sewage pump 55 to pump the preliminarily filtered sludge mixed sewage entering the sewage collecting bin 35 into the sewage barrel 25, and the sludge and sewage first enter the centrifuge barrel 31 through the sewage pipe 54. At this time, the third motor 38 is started to drive the centrifuge barrel 31 to rotate at high speed through the locking groove 34 and the locking plate 36. The centrifugal force of the rotation of the centrifuge barrel 31 is used to separate the sludge and sewage. The sludge is retained by the filter screen 33 and the sewage enters the sewage barrel 25. The sludge and sewage will be treated separately in the future.

[0042] At the same time, the water pump 26 pumps the sewage that has been filtered and enters the sewage barrel 25 back into the silt removal bucket 11, thereby diluting the sludge that has been squeezed and filtered in the silt removal bucket 11, and further allowing the small particles in the sludge to obtain better fluidity, making it easier for it to pass through the filter tank 17 to improve the filtration efficiency. By setting a one-way valve 28, it can effectively prevent the sludge from flowing back into the water pipe 27 and clogging the pipe.

[0043] When the impeller 12 drives the scraper 14 to continue to rotate, and the space between the impeller 12 and the silt cleaning bucket 11 gradually becomes larger, small particles and sewage completely pass through the filter tank 17 and enter the sewage collecting bin 35. At this time, only stones or plant fibers that cannot pass through the filter tank 17 remain between the silt cleaning bucket 11 and the impeller 12. At this time, the impurities in the impurities drive the scraper 14 to continue to rotate, and move the large particles to the bottom of the suction sleeve 42. The fan 45 that is always working continuously draws suction to generate suction, and the impurities are sucked into the collection box 44 through the suction sleeve 42 and the air duct 43. After entering the collection box 44, the impurities are intercepted by the filter element 47 and then remain in the collection box 44.

[0044] Moreover, during the continuous rotation of the rotating wheel 12, the cleaning needle 16 is also moved along with it, and due to the eccentric setting of the rotating wheel 12 and the dredging bucket 11, the cleaning needle 16 will gradually approach and insert into the corresponding filter tank 17, and finally move out of the filter tank 17 again, thereby continuously cleaning the filter tank 17, effectively removing stones and plant fibers stuck in the filter tank 17, avoiding clogging the filter tank 17 and affecting the efficiency of subsequent filtration, thereby ensuring the dredging effect.

[0045] Finally, after the dredging of the canal is completed, the operator closes the device, then opens the drain valve 41 to discharge the sewage stored at the bottom of the sewage barrel 25, then holds the handle 40, screws the large high-density battery 49 and rotates the locking plate 36 and the locking groove 34 to disengage, so that the locking plate 36, the transmission shaft 37, the third motor 38 and the barrel cover 39 can be removed, and then the operator takes out the filter screen 33 with sludge, and processes the sewage and sludge respectively. Finally, the box cover 46 is opened to remove the filter element 47, and the large particles of impurities collected in the collection box 44 are cleaned to complete the dredging work.

[0046] The above-mentioned sewage valve 41, the second motor 52, the high-density battery 49, the third motor 38, the fan 45, the sewage pump 55, the water pump 26, etc. are mature existing technologies and will not be described in detail herein.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
