Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a device for desilting water conservancy projects. Background Art

[0002] In water conservancy projects, large amounts of silt often accumulate in rivers, reservoirs and other water areas. This silt not only affects the fluidity and water quality of the water area, but may also pose a threat to the normal operation of water conservancy facilities.

[0003] Traditional dredging methods mainly use manual dredging or large-scale mechanical dredging. Manual dredging is inefficient, labor-intensive, and poses safety hazards; large-scale mechanical dredging is costly, has high site requirements, and may cause damage to the surrounding environment.

[0004] To this end, we propose a device based on dredging of water conservancy projects. Utility Model Content

[0005] The main purpose of the present invention is to provide a device for dredging water conservancy projects, in order to prevent the flow and water quality of water areas such as rivers and reservoirs from being affected by silt accumulation, and to avoid threats to the normal operation of water conservancy facilities. At the same time, it solves the problems of low efficiency, high labor intensity, safety hazards of manual dredging and high cost of large-scale mechanical dredging, high site requirements, and possible damage to the surrounding environment in traditional dredging methods, thereby improving dredging efficiency, reducing dredging costs and reducing damage to the surrounding environment, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A device for desilting in water conservancy projects, comprising a vehicle body, wherein two sets of relatively parallel brackets are provided on the top of the vehicle body, and connecting frames are provided on opposite sides of the two sets of brackets. The opposite sides of the two sets of connecting frames are rotatably connected to a rotating shaft via a bearing, a worm gear is fixedly connected to the outside of the rotating shaft and located inside the connecting frame, and a worm is rotatably connected to the inside of the connecting frame via a bearing, a first drive motor is fixedly installed at one end of the connecting frame, an output shaft of the first drive motor passes through the connecting frame and is fixedly connected to the worm, and the worm is meshed with the worm gear;

[0008] The two groups of rotating shafts are fixedly connected to a storage tank at one end away from the connecting frame, a feed port is provided on the upper part of one side of the storage tank, a discharge port is provided at the bottom end of the storage tank, and valves are provided in the discharge port and the feed port. A second drive motor is fixedly installed on the top of the storage tank, and the output shaft of the second drive motor is fixedly connected to a rotating rod, a stirring rod is fixedly connected to the middle part of the outer side of the rotating rod, and the upper and lower parts of the outer side of the rotating rod are fixedly connected to connecting rods, and a scraper is fixedly connected to the end of the connecting rod away from the rotating rod, and the scraper is in contact with the inner wall of the storage tank.

[0009] By adopting the above technical solution, the first drive motor is started, and the output shaft of the first drive motor drives the worm to rotate. Since the worm is engaged with the worm wheel, the rotation of the worm drives the rotation of the worm wheel. The worm wheel is fixed to the rotating shaft, and the rotating shaft is rotatably connected to the connecting frame through a bearing. The rotation of the worm wheel drives the rotating shaft to rotate. The other end of the rotating shaft is connected to the storage tank, thereby realizing the adjustment of the angle of the storage tank to better meet the different dredging operation requirements.

[0010] When the storage tank is adjusted to the appropriate angle, the equipment is moved to the dredging position, so that silt and other debris enter the storage tank through the feed port. The feed port is equipped with a valve to control the opening and closing of the feed;

[0011] The second drive motor is started, and the output shaft of the second drive motor drives the rotating rod to rotate. The stirring rod in the middle of the outer side of the rotating rod stirs the sludge entering the storage tank to prevent the sludge from settling and solidifying;

[0012] After the silt cleaning work of the water conservancy project is completed, the staff adds water to the storage tank and starts the first drive motor again. The storage tank is rotated through the transmission of the worm and worm gear. During the rotation process, the water in the storage tank can fully fit into various internal parts to soak and loosen the residual silt; at the same time, the second drive motor is started to drive the rotating rod to rotate. The scraper on the rotating rod continuously scrapes off the residual silt on the inner wall as the storage tank rotates. The stirring rod further stirs the water and residual silt during the rotation process, making the cleaning more thorough. By rotating and stirring at the same time, the residual silt inside the storage tank can be efficiently cleaned to ensure the cleanliness of the storage tank and prepare for the next dredging operation.

[0013] Furthermore, the connecting frame is fixedly mounted on the middle of the top end of the vehicle body by means of fixing bolts, and a handle is welded on the top end of the vehicle body near one end edge.

[0014] By adopting the above technical solution, the connecting frame provides stable support for components such as the rotating shaft, worm gear, and worm, and the fixing bolts connect the storage tank to the vehicle body, which is connected to the storage tank through the rotating shaft on the connecting frame, so that the storage tank can be adjusted in angle under the action of the first drive motor. The fixing bolts ensure that the connection between the connecting frame and the vehicle body is firm and reliable, and will not loosen or fall off during the operation of the equipment. When the equipment needs to be moved to a different dredging position, the staff can hold the handle and push the vehicle body by manpower. The position design of the handle facilitates the staff to apply force, so that the equipment can be flexibly moved at the water conservancy project site.

[0015] Furthermore, a water pump is fixedly installed at the edge of the top end of the vehicle body away from the handle.

[0016] By adopting the above technical solution, the position of the water pump avoids being too concentrated with the components on the handle side, making the weight distribution of the vehicle body more balanced, improving the stability of the equipment during movement and operation, and at the same time, when performing the water pump extraction operation, there will be no conflict with the action of pushing the equipment.

[0017] Furthermore, a delivery hose is fixedly connected to the suction end of the water pump, and a connecting hose is fixedly installed on the discharge end of the water pump.

[0018] By adopting the above technical solution, when the water pump is working, it absorbs silt through the delivery hose. The softness of the delivery hose makes it easy to extend to water sources at different locations. When the water pump is started, negative pressure is generated inside it. This negative pressure is transmitted to the silt through the delivery hose, so that the silt is sucked into the delivery hose under the action of the pressure difference and flows to the water pump. The inner diameter and material selection of the delivery hose ensure the smooth passage of water. At the same time, its flexibility also prevents it from being easily damaged by pulling when the equipment is moved or adjusted.

[0019] After the water pump sucks in and pressurizes the silt, the silt flows out from the discharge end and enters the connecting hose, which transports the pressurized silt to the storage tank. The length and flexibility of the connecting hose allow the discharge position to be adjusted according to actual needs, improving the flexibility and adaptability of the equipment. At the same time, the connecting hose can also withstand a certain amount of water pressure to ensure that the silt will not leak or break during transportation.

[0020] Furthermore, one end of the connecting hose away from the water pump is connected to the feed port and communicates with the interior of the storage tank.

[0021] By adopting the above technical solution, when the storage tank needs to be cleaned or there is a specific need, the water pump is started, and the water pump draws water from an external water source through a delivery hose. After pressurization, the water flows into the connecting hose from the discharge end of the water pump. Since the end of the connecting hose away from the water pump is connected to the feed port and is connected to the inside of the storage tank, the water will flow along the connecting hose into the feed port and then into the inside of the storage tank. If the cleaning operation is performed after the dredging work is completed, the water entering the storage tank can flush the silt remaining on the inner wall of the tank. On the one hand, the flow of water can loosen the silt attached to the tank wall, making it easier to clean it; on the other hand, when the second drive motor starts to drive the rotating rod to rotate, the stirring rod and scraper stir and scrape the water and silt, and the connecting hose continuously supplies water, ensuring that there is enough water flow to rinse various parts of the tank during the cleaning process, thereby achieving effective cleaning of the inside of the storage tank and ensuring that the storage tank remains clean when used next time.

[0022] Furthermore, universal wheels are fixedly installed at the four corners of the bottom end of the vehicle body, and the four universal wheels are symmetrically arranged in pairs.

[0023] By adopting the above technical solution, the universal wheels at the bottom of the vehicle body play a key role in movement and support.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The utility model is a device for dredging water conservancy projects. The device can quickly adjust the angle of the storage tank through the cooperation of the first drive motor, the worm, the worm wheel and the rotating shaft to adapt to different dredging operation requirements, thereby improving the flexibility and efficiency of dredging. The stirring rod and the scraper in the storage tank are driven by the second drive motor to stir and scrape the silt to prevent the silt from settling and solidifying. At the same time, when cleaning the residual silt, the method of rotating and stirring at the same time can efficiently clean the residual silt inside the storage tank, ensure the cleanliness of the storage tank, and prepare for the next dredging operation, thereby greatly improving the efficiency of dredging.

[0026] (2) The utility model is a device for dredging water conservancy projects. Compared with large-scale mechanical dredging, the device has a lower cost and does not require a high site, and is suitable for dredging operations in various water conservancy projects. During the dredging process, the device can effectively store and treat the silt, avoiding the pollution of the surrounding environment by the silt. At the same time, when cleaning the residual silt, the method of adding water and rotating stirring is adopted, which reduces the use of chemical cleaning agents and is more environmentally friendly.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] In order to prevent the flow and water quality of rivers, reservoirs and other water areas from being affected by silt accumulation, and to avoid threats to the normal operation of water conservancy facilities, and to solve the problems of low efficiency, high labor intensity, safety hazards and high cost of large-scale mechanical silt removal in traditional silt removal methods, high site requirements and possible damage to the surrounding environment, the silt removal efficiency can be improved, the silt removal cost can be reduced and the damage to the surrounding environment can be reduced. Figure 1 、 Figure 2 、 Figure 3 As shown, a device for dredging silt in water conservancy projects includes a vehicle body 1, with two sets of relatively parallel brackets 2 provided on the top of the vehicle body 1, and connecting frames 3 provided on opposite sides of the two sets of brackets 2. The two sets of connecting frames 3 are rotatably connected to the rotating shaft 21 on the opposite sides through bearings. A worm gear 4 is fixedly connected to the outside of the rotating shaft 21 and located inside the connecting frame 3. A worm 6 is rotatably connected to the inside of the connecting frame 3 through bearings. A first drive motor 7 is fixedly installed at one end of the connecting frame 3. The output shaft of the first drive motor 7 passes through the connecting frame 3 and is fixedly connected to the worm 6. The worm 6 is meshed with the worm gear 4.

[0033] The two groups of rotating shafts 21 are fixedly connected to the storage tank 5 at one end away from the connecting frame 3, and a feed port 8 is provided on the upper part of one side of the storage tank 5, and a discharge port 9 is provided at the bottom end of the storage tank 5. Valves are provided in the discharge port 9 and the feed port 8, and a second drive motor 10 is fixedly installed on the top of the storage tank 5. The output shaft of the second drive motor 10 is fixedly connected to the rotating rod 11, and the middle part of the outer side of the rotating rod 11 is fixedly connected to the stirring rod 12. The upper and lower parts of the outer side of the rotating rod 11 are fixedly connected to the connecting rod 13, and the connecting rod 13 is fixedly connected to the scraper 14 at one end away from the rotating rod 11, and the scraper 14 is in contact with the inner wall of the storage tank 5.

[0034] When in use, the first drive motor 7 is started, and the output shaft of the first drive motor 7 drives the worm 6 to rotate. Since the worm 6 is engaged with the worm wheel 4, the rotation of the worm 6 drives the worm wheel 4 to rotate. The worm wheel 4 is fixed on the rotating shaft 21. The rotating shaft 21 is rotatably connected to the connecting frame 3 through a bearing. The rotation of the worm wheel 4 drives the rotating shaft 21 to rotate. The other end of the rotating shaft 21 is connected to the storage tank 5, thereby realizing the adjustment of the angle of the storage tank 5 to better meet the different dredging operation requirements;

[0035] When the storage tank 5 is adjusted to a suitable angle, the equipment is moved to the dredging position, so that silt and other debris enter the storage tank 5 through the feed port 8. A valve is provided in the feed port 8 to control the opening and closing of the feed;

[0036] The second drive motor 10 is started, and the output shaft of the second drive motor 10 drives the rotating rod 11 to rotate. The stirring rod 12 in the middle of the outer side of the rotating rod 11 stirs the sludge entering the storage tank 5 to prevent the sludge from settling and solidifying.

[0037] After the silt cleaning work of the water conservancy project is completed, the staff adds water to the storage tank 5 and starts the first drive motor 7 again. The storage tank 5 is rotated through the transmission of the worm 6 and the worm gear 4. During the rotation process, the water in the storage tank 5 can fully fit into various internal parts to soak and loosen the residual silt; at the same time, the second drive motor 10 is started to drive the rotating rod 11 to rotate. The scraper 14 on the rotating rod 11 continuously scrapes off the silt remaining on the inner wall as the storage tank 5 rotates. The stirring rod 12 further stirs the water and residual silt during the rotation process, making the cleaning more thorough. By rotating and stirring at the same time, the silt remaining inside the storage tank 5 can be efficiently cleaned to ensure the cleanliness of the storage tank 5 and prepare for the next silt cleaning operation.

[0038] For example, Figure 1 、 Figure 3 As shown, the present invention further includes that the connecting frame 3 is fixedly mounted on the top middle portion of the vehicle body 1 by means of fixing bolts 15 , and a handle 19 is welded on the top of the vehicle body 1 and near one end edge.

[0039] When in use, the connecting frame 3 provides stable support for components such as the rotating shaft 21, the worm gear 4, and the worm 6. The fixing bolts 15 connect the storage tank 5 to the vehicle body 1, and are connected to the storage tank 5 through the rotating shaft 21 on the connecting frame, so that the storage tank can be adjusted in angle under the action of the first drive motor 7. The fixing bolts ensure that the connection between the connecting frame and the vehicle body is firm and reliable, and will not loosen or fall off during the operation of the equipment. When the equipment needs to be moved to a different dredging position, the staff can hold the handle 19 and push the vehicle body by manpower. The position design of the handle 19 is convenient for the staff to apply force, so that the equipment can be flexibly moved at the water conservancy project site.

[0040] For example, Figure 1 As shown, the present invention further includes a water pump 16 fixedly mounted on the top edge of the vehicle body 1 and away from the handle 19 .

[0041] When in use, the position of the water pump 16 avoids being too concentrated with the components on the side of the handle 19, so that the weight distribution of the vehicle body 1 is more balanced, and the stability of the equipment during movement and operation is improved. At the same time, when performing the extraction operation with the water pump 16, there will be no conflict with the action of pushing the equipment.

[0042] For example, Figure 1 As shown, the present invention further includes that the suction end of the water pump 16 is fixedly connected to a delivery hose 17 , and the discharge end of the water pump 16 is fixedly installed with a connecting hose 18 .

[0043] When in use, the water pump 16 absorbs silt through the delivery hose 17 when it is working. The softness of the delivery hose 17 allows it to be easily extended to water sources at different locations. When the water pump 16 is started, negative pressure is generated inside it. This negative pressure is transmitted to the silt through the delivery hose 17, so that the silt is sucked into the delivery hose 17 under the action of the pressure difference and flows to the water pump 16. The inner diameter and material selection of the delivery hose 17 ensure the smooth passage of water. At the same time, its flexibility also prevents it from being easily damaged by pulling when the equipment is moved or adjusted.

[0044] After the water pump 16 sucks in and pressurizes the silt, the silt flows out from the discharge end and enters the connecting hose 18, which transports the pressurized silt to the storage tank 5; the length and flexibility of the connecting hose 18 make it possible to adjust the discharge position according to actual needs, thereby improving the flexibility and adaptability of the equipment; at the same time, the connecting hose 18 can also withstand a certain water pressure to ensure that the silt will not leak or break during the transportation process.

[0045] For example, Figure 1 As shown, the present invention further includes that one end of the connecting hose 18 away from the water pump 16 is connected to the feed port 8 and communicates with the interior of the storage tank 5 .

[0046] In use, when the storage tank 5 needs to be cleaned or has specific needs, the water pump 16 is started, the water pump sucks water from an external water source through the delivery hose 17, and after being pressurized, the water flows into the connecting hose 18 from the discharge end of the water pump, and since the end of the connecting hose 18 away from the water pump 16 is connected to the feed inlet 8 and communicates with the inside of the storage tank 5, the water will flow into the feed inlet 8 along the connecting hose and then into the inside of the storage tank 5. If the cleaning operation is performed after the dredging work is completed, the water entering the storage tank 5 can flush the silt remaining on the inner wall of the tank. On the one hand, the flow of water can loosen the silt adhering to the tank wall, making it easier to be cleaned; on the other hand, when the second drive motor 10 is started to drive the rotating rod 11 to rotate, the stirring rod 12 and the scraper 14 stir and scrape the water and silt, and the connecting hose continuously supplies water, ensuring that there is enough water flow to flush each part of the tank during the cleaning process, thereby achieving effective cleaning of the inside of the storage tank 5 and ensuring that the storage tank remains clean for the next use.

[0047] For example, as shown in Figure 1 The utility model also includes, four universal wheels 20 are symmetrically arranged in pairs and fixedly installed at the bottom end of the vehicle body 1.

[0048] In use, the universal wheels 20 at the bottom end of the vehicle body 1 play a key role in moving and supporting.

[0049] It should be noted that the utility model is a device based on water conservancy engineering dredging. The first drive motor 7 is started, the output shaft of the first drive motor 7 drives the worm 6 to rotate, the worm 6 drives the worm gear 4 to rotate, thereby rotating the shaft 21, adjusting the storage tank 5 to an appropriate angle to adapt to the dredging operation requirements. The staff holds the handle 19 and pushes the vehicle body 1 by hand, taking advantage of the flexibility of the universal wheels 20, to move the device to the dredging position. The water pump 16 can suck silt through the delivery hose 17, and the silt enters the storage tank 5 through the connecting hose 18 under the action of the water pump. The second drive motor 10 is started, the output shaft of the second drive motor 10 drives the rotating rod 11 to rotate, and the stirring rod 12 stirs the silt entering the storage tank 5 to prevent the silt from settling and consolidating.

[0050] The valve of the feed inlet 8 is closed, the feeding is stopped, the device is moved to an appropriate discharge or treatment site, the discharge pipe is connected to the discharge outlet 9, and then the valve of the discharge outlet 9 is opened to discharge the silt in the storage tank 5.

[0051] Close the valve of the discharge port 9, open the valve of the feed port 8, and the water pump 16 draws water from the external water source through the delivery hose 17, and adds water to the storage tank 5 through the connecting hose 18. After the water adding is completed, unplug the connecting hose 18 on the storage tank 5, close the valve of the feed port 8, and start the first drive motor 7 again. The storage tank 5 is rotated through the transmission of the worm 6 and the worm gear 4, so that the water can fully fit into various parts of the storage tank 5 to soak and loosen the residual silt; at the same time, start the second drive motor 10 to drive the rotating rod 11 to rotate. The scraper 14 continuously scrapes off the residual silt on the inner wall as the storage tank 5 rotates, and the stirring rod 12 further stirs the water and residual silt to make the cleaning more thorough.
