Description

Technical Field

[0001] This application relates to the field of dredging equipment, and in particular to a channel dredging device for water conservancy and hydropower. Background Technology

[0002] Water conservancy and hydropower engineering involves knowledge of surveying, planning, design, construction, scientific research and management of water conservancy and hydropower projects. Farmland irrigation often uses river water to introduce water into farmland. Water canals are artificially excavated waterways, which are divided into main canals and branch canals. Main canals and branch canals are generally constructed with stone or cement.

[0003] Chinese Patent Publication No. CN218060507U discloses a high-efficiency dredging device for water conservancy and hydropower construction, belonging to the field of water conservancy engineering. The key technical points include: a water channel and a vehicle body slidably connected to the water channel. The vehicle body is equipped with a sludge collection tank, a water pump, and a sludge collection pipe with telescopic function. The sludge collection tank, water pump, and sludge collection pipe are connected in sequence. A sludge scraping mechanism is provided at the opening of the sludge collection pipe. In use, during dredging, the vehicle body is placed on the water channel, and the sludge collection pipe is adjusted to a suitable length according to the depth of the water channel. The vehicle body is manually pushed along the water channel, and the sludge scraping mechanism scrapes up the sludge adhering to the bottom wall of the water channel. Under the action of the water pump, the sludge enters the sludge collection tank. The device has good dredging effect, high dredging efficiency, and low dredging cost.

[0004] In the aforementioned technologies, the dredging device uses a scraper to agitate the silt, which cannot effectively wash the silt in the channel. When the silt is relatively dry, the sludge pump cannot effectively extract the silt, and some silt will adhere to the inside of the channel. Therefore, a channel dredging device for water conservancy and hydropower is proposed to solve the above problems. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a channel dredging device for water conservancy and hydropower.

[0027] Reference Figures 1 to 6 A channel dredging device for water conservancy and hydropower includes a dredging trolley 1, a cleaning component 2, a cleaning component 3, a sewage discharge component 4, and a scraper 5. The cleaning component 2 is installed on the dredging trolley 1 and is used to clean the inside of the target channel. The cleaning component 3 is installed at the front end of the dredging trolley 1 and is used to clean the top road of the target channel. The sewage discharge component 4 is installed on the dredging trolley 1 and is used to pump out the sewage generated during the cleaning of the target channel. The scraper 5 is installed at the bottom end of the dredging trolley 1 through a limiting component 6.

[0028] The dredging trolley 1 is placed on the top road of the target channel. The cleaning component 2 sprays water to clean the inside of the target channel and generates cleaning wastewater. The cleaning component 3 sweeps the dust on the top road of the target channel to facilitate the movement of the dredging trolley 1. The scraper 5 can hang the wastewater on the channel wall of the target channel and collect the wastewater, and then discharge the wastewater through the sewage discharge component 4.

[0029] The cleaning assembly 2 includes a water tank 21, a booster pump 22, a water supply pipe 23, and multiple nozzles 24. The water tank 21 is fixedly installed on the top of the dredging trolley 1. The booster pump 22 is also installed on the top of the dredging trolley 1. The inlet of the booster pump 22 is connected to the water tank 21 via a connecting pipe, and the outlet of the booster pump 22 is connected to an output pipe. The multiple nozzles 24 are all installed on the front end of the water supply pipe 23 away from the booster pump 22. It should be noted that a clamping block 11 for fixing the water supply pipe 23 is installed at the front end of the dredging trolley 1.

[0030] After being pressurized by the booster pump 22, the water in the water storage tank 21 flows into multiple nozzles 24 through the water delivery pipe 23, and the multiple nozzles 24 clean the target channel.

[0031] The cleaning component 3 includes a rotating motor 31, a rotating shaft 32, and a cleaning brush 33. The rotating motor 31 is horizontally fixedly installed at the front end of the dredging trolley 1, the rotating shaft 32 is horizontally installed at the output end of the rotating motor 31, and the cleaning brush 33 is installed on the circumferential wall of the rotating shaft 32.

[0032] When the rotating motor 31 is working, it can drive the rotating shaft 32 to rotate, and the rotating shaft 32 drives the cleaning brush 33 to rotate. The cleaning brush 33 sweeps the dust on the top road of the target channel, making it easier for the dredging vehicle 1 to move.

[0033] The sewage discharge assembly 4 includes a water pump 41, a suction pipe 42, and a sewage discharge pipe 43. The water pump 41 is installed on the top of the dredging trolley 1, the suction pipe 42 is installed at the inlet end of the water pump 41, and the sewage discharge pipe 43 is installed at the outlet end of the suction pipe.

[0034] As the dredging vehicle 1 moves, the scraper 5 collects the sewage in the target channel, and then the water pump 41 sucks up the sewage in the target channel through the suction pipe 42 and discharges it through the drain pipe.

[0035] The top of the dredging trolley 1 has a semi-circular groove 12, and a support rod 13 is slidably installed in the semi-circular groove 12. A nut 14 is threaded on the support rod 13 and abuts against the top of the dredging trolley 1. A U-shaped block 15 is fixedly installed at the top of the support rod 13. A clamp 16 is installed in the U-shaped block 15 through an adjustment component. The sewage pipe 43 is installed on the clamp 16.

[0036] When it is necessary to adjust the horizontal discharge direction of the sewage pipe 43, screw the nut 14 upwards, then move the support plate along the semi-circular groove 12. After reaching the designated position, screw the nut 14 downwards until the nut 14 abuts against the top of the sludge removal trolley 1.

[0037] The inner wall of the U-shaped block 15 has multiple receiving grooves 151 distributed circumferentially at opposite ends. The clamp 16 has multiple hemispherical grooves 161 on opposite outer walls. The adjustment assembly includes an adjustment spring 72 and an adjustment ball 71. The adjustment spring 72 is located in the receiving groove 151. One end of the adjustment spring 72 is fixedly connected to the bottom of the receiving groove 151, and the other end is fixedly connected to the adjustment ball 71. The adjustment ball 71 is located in the hemispherical groove 161.

[0038] When it is necessary to adjust the vertical discharge direction of the drain pipe 43, rotate the clamp 16. The groove wall of the hemispherical groove 161 on the clamp 16 will apply a pressure to the adjusting ball 71, causing the adjusting ball 71 to move toward the corresponding receiving groove 151 and compress the adjusting spring 72. After the clamp 16 is rotated to the appropriate position, the adjusting spring 72 returns to its original position, causing the adjusting ball 71 to slide into the hemispherical groove 161.

[0039] Two connecting blocks 17 are fixedly installed at the bottom of the dredging trolley 1. Each connecting block 17 has a slot 171 at its bottom. A limiting hole 172 is provided on the front and rear walls of the slot 171. The front and rear ends of the connecting block 17 have placement slots 173 corresponding to the limiting holes 172. The top of the scraper 5 is inserted into the slot 171. The scraper 5 has a limiting groove 51 corresponding to the limiting holes 172. The limiting components 6 are provided in four sets, one limiting group. Component 6 corresponds to a limiting groove 51. A set of limiting components 6 includes a limiting rod 61, a limiting spring 62, and a limiting plate 63. One end of the limiting rod 61 is inserted into the limiting groove 51, and the other end passes through the limiting hole 172 and is located in the placement groove 173. The limiting plate 63 is located at the opening of the placement groove 173 and is fixedly connected to the limiting rod 61. The limiting spring 62 is looped around the limiting rod 61. One end of the limiting spring 62 is fixedly connected to the bottom of the placement groove 173, and the other end is fixedly connected to the limiting plate 63. It should be noted that the end of the limiting rod 61 inserted into the limiting groove 51 is a downward-sloping surface.

[0040] When the scraper 5 needs to be installed, move the scraper 5 upwards. The scraper 5 will apply pressure to the inclined end of the limiting rod 61, causing the limiting rod 61 to slide into the limiting hole 172. The limiting rod 61 drives the corresponding limiting plate 63 to move away from the inside of the corresponding slot 171. The limiting plate 63 stretches the limiting spring 62. Continue to move the scraper 5 upwards. When the limiting groove 51 on the scraper 5 corresponds to the limiting hole 172 on the connecting block 17, the limiting spring 62 returns to its original position. The limiting spring 62 drives the corresponding limiting plate 63 to move closer to the inside of the corresponding slot 171. The limiting plate 63 drives the inclined end of the limiting rod 61 to slide into the limiting groove 51, completing the installation of the scraper 5 and achieving a labor-saving effect.

[0041] When it is necessary to remove the scraper 5, pull the limiting plate 63, causing the limiting plate 63 to move away from the inside of the corresponding slot 171. The limiting plate 63 drives the corresponding limiting rod 61 to move away from the inside of the corresponding slot 171 until the inclined end of the limiting rod 61 slides out of the limiting groove 51. The scraper 5 no longer has the limiting effect of the limiting rod 61 and can slide out of the slot 171.

[0042] It should be noted that the scraper 5 is installed on the connecting block 17 of the dredging trolley 1 by the limiting component 6, so that the shape of the scraper 5 can be changed at any time.

[0043] The implementation principle of a channel dredging device for water conservancy and hydropower in this application embodiment is as follows: the scraper 5 is installed on the connecting block 17 of the dredging trolley 1 by the limiting component 6, the dredging trolley 1 is placed on the top road of the target channel, the cleaning component 2 sprays water to clean the inside of the target channel and generates cleaning wastewater, the cleaning component 3 sweeps the dust on the top road of the target channel to facilitate the movement of the dredging trolley 1, the scraper 5 can hang the wastewater on the channel wall of the target channel and collect the wastewater, and then discharge the wastewater through the sewage discharge component 4, which has the advantage of facilitating the flushing of silt. When the silt is relatively dry, the water pump can effectively extract the silt, which improves the cleaning effect to a certain extent.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
