Description

Technical Field

[0001] This invention relates to the field of water channel silt removal technology, specifically a small-scale mobile water jet flushing device for artificial open channels. Background Technology

[0002] In the field of water conservancy engineering, artificial open channels are crucial infrastructure for water resource allocation and irrigation. With economic and social development, the construction and use of artificial open channels have become increasingly widespread, playing a vital role in ensuring water supply for agricultural production, industry, and residential use. The proper functioning of artificial open channels enables the rational allocation and efficient utilization of water resources, promotes sustainable regional economic development, and possesses irreplaceable value in improving the ecological environment and safeguarding people's livelihoods.

[0003] Siltation is a common and pressing problem in the operation of artificial open channels. To address this issue, existing technologies often employ the following methods: One is manual dredging, where manpower is deployed using simple tools such as shovels and buckets to remove silt from the channel. While this method is relatively low-cost, it is labor-intensive, inefficient, and ineffective at clearing silt from deep within the channel or in hidden areas. Another method involves using large-scale dredging equipment, such as dredgers, to mechanically excavate silt from the channel. This method can handle large quantities of silt, but the equipment is bulky and complex to operate. For small artificial open channels, using large dredging equipment is not only costly but also difficult to implement in narrow spaces. A third method involves setting up fixed sand-blocking structures, such as sand-retaining dams, to intercept silt before it enters the channel. However, this method only provides some preventative effect and cannot effectively remove silt that has already entered the channel.

[0004] The shortcomings of existing technologies are that manual dredging is inefficient and labor-intensive, making it difficult to meet the needs of large-scale dredging; large dredging equipment is not suitable for small artificial open channels due to its high cost and inconvenient operation; and fixed sand-blocking facilities cannot remove existing silt from the open channels. These problems make it difficult to effectively solve the siltation problem in small artificial open channels, affecting the normal use of the channels and the efficiency of water resource allocation. Summary of the Invention

[0005] The purpose of this invention is to provide a small-scale, mobile, artificial open channel water jet flushing device to solve the problems mentioned in the background art.

[0013] Optionally, the small-scale artificial open channel mobile water-flushing and sand-flushing equipment also includes a hydraulic pump, hydraulic pipes, and four hydraulic lifting rods. The four hydraulic lifting rods are installed at the four corners of the water storage tank. The hydraulic pump is connected to the four hydraulic lifting rods through hydraulic pipes. The extension and retraction of the hydraulic lifting rods drive the water storage tank to rise and fall.

[0014] Optionally, the small-scale artificial open channel mobile water-spraying and sand-flushing equipment also includes a control circuit, which includes a power supply, a first switch, a second switch, a sliding rheostat, a gate lifting switch, a gate lowering switch, a first electromagnet, a second electromagnet, a third electromagnet, a fourth electromagnet, a first double-control spring switch, and a second double-control spring switch.

[0015] The power supply, the first switch, and the water pump are connected in series.

[0016] The power supply, the second switch, the sliding rheostat, and the air pump are connected in series.

[0017] The power supply, the gate lifting switch, the first electromagnet and the fourth electromagnet are connected in series;

[0026] Compared with the prior art, the present invention provides a small-scale, mobile, water-jetting sand-flushing device for artificial open channels, which has the following beneficial effects:

[0027] 1. The water pump can draw water from the canal into the water storage tank, which is used to hold water, increasing the weight of the entire equipment and thus stabilizing it in the canal. When the drain valve is opened, the water in the water storage tank is discharged from the drain outlet, using the impact force of the water flow to flush away sand and solve the problem of siltation in small artificial open channels. This method is more efficient than manual dredging.

[0028] 2. The drive mechanism can drive the water baffle plate to move in the vertical direction. When the water baffle plate descends, it will reduce the water flow cross section and make the water flow more turbulent, thereby achieving sand flushing.

[0029] 3. The air pump's outlet pipe can blow away mud and sand, which, combined with the drainage of the water storage tank and the baffle plate, makes the water flow more turbulent and has a sand-flushing effect, can more effectively clean the mud and sand in the open channel.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] Example 1

[0038] Please see Figure 1-3 This invention provides a technical solution, which will be further described in detail below with reference to the accompanying drawings. The described embodiments are merely possible technical implementations of this invention, but are not limited thereto. Those skilled in the art can certainly combine the embodiments of this invention to obtain other embodiments without creative effort, which are also within the protection scope of this invention.

[0039] This application mainly uses a water storage tank 1 in conjunction with multiple components to achieve water-flushing and sand flushing, which achieves the effect of efficiently cleaning up the siltation problem in small artificial open channels. The following is a further detailed description of this application.

[0040] Example 1

[0041] The small-scale mobile water-flushing and sand-flushing device for artificial open channels provided in this application includes a water storage tank 1, a water pump 2, a water-blocking valve plate 3, a drive mechanism 4, and an air pump 5. The water pump 2 draws water into the water storage tank 1, the drive mechanism 4 controls the vertical movement of the water-blocking valve plate 3 within the mounting slot of the water storage tank 1, and the air pump 5 blows away sediment through its outlet pipe, achieving the effect of efficiently cleaning sediment from the small-scale artificial open channel. This is because the combined action of the water pump 2 storing water, the water-blocking valve plate 3 regulating water flow, and the air pump 5 assisting in sand flushing can effectively clean sediment in different locations and conditions.

[0042] Specifically, the water storage tank 1 is hollow, with a drain outlet at its bottom, and a drain valve 6 is installed on the drain outlet. The drain outlet and drain valve 6 facilitate the discharge of water and sediment from the water storage tank 1. The inner bottom surface of the water storage tank 1 is sloped, with the lowest point of the slope located at the drain outlet. This slope design promotes the collection of water and sediment towards the drain outlet for easy discharge. A lifting ring 26 is also installed on the inner bottom surface of the water storage tank 1. The lifting ring 26 can be used for lifting and moving the equipment. For example, when it is necessary to remove the equipment from the open channel for maintenance or relocation, it can be lifted using a crane or other tools via the lifting ring 26. A vertically oriented mounting groove is provided on the wall of the water storage tank 1 facing the direction of water flow, providing a track for the sliding of the water baffle plate 3.

[0043] Water pump 2 is fixedly installed on water storage tank 1. The inlet of water pump 2 is used to connect the pipeline to the channel water, and the outlet of water pump 2 is used to connect the pipeline to the interior of water storage tank 1. Water pump 2 can be a centrifugal pump or similar type, which has the advantages of simple structure and convenient operation. When water pump 2 is working, it draws in channel water through the inlet and then delivers it to water storage tank 1 through the outlet, realizing the water storage function. This increases the weight of the equipment, allowing it to be placed stably in the channel.

[0044] The water-blocking valve plate 3 is slidably installed in the mounting groove. An auxiliary water-blocking plate 27 is installed below the water-blocking valve plate 3. The auxiliary water-blocking plate 27 is detachably connected to the water-blocking valve plate 3, and its shape is adapted to the cross-sectional shape of the water channel. The auxiliary water-blocking plate 27 enhances the water-blocking effect. Appropriate auxiliary water-blocking plates 27 can be replaced according to the cross-sectional shape of different water channels, improving the applicability of the equipment. The water-blocking valve plate 3 can be made of stainless steel or other materials, possessing good corrosion resistance and strength, and can be used in water for extended periods. Under the action of the drive mechanism 4, the water-blocking valve plate 3 moves vertically within the mounting groove. By adjusting its position, the cross-sectional size of the water flow can be changed. When the water-blocking valve plate 3 descends, the water flow cross-section decreases, and the water flow becomes more turbulent, thus increasing the impact force of the water flow and achieving the function of water-binding and sand-flushing.

[0045] The drive mechanism 4 is installed on the water storage tank 1. The output end of the drive mechanism 4 is connected to the upper end of the baffle plate 3, and is used to drive the baffle plate 3 to move vertically. The drive mechanism 4 includes a motor 7, a driving gear 8, a driven gear 9, and a screw 10. The motor 7 is fixedly installed on the water storage tank 1, and the shaft of the motor 7 is fixedly connected to the driving gear 8. The driven gear 9 is rotatably installed on the water storage tank 1, and a thread is formed in the middle of the driven gear 9. The screw 10 is screwed into the driven gear 9, and the lower end of the screw 10 is fixed vertically to the upper end of the baffle plate 3 and rotatably connected in the circumferential direction. When the motor 7 starts, it drives the driving gear 8 to rotate, which in turn drives the driven gear 9 to rotate. The rotation of the driven gear 9 causes the screw 10 to move vertically, thereby driving the baffle plate 3 to move vertically. The motor 7 can be a stepper motor, which can precisely control the moving position and speed of the baffle plate 3. The setting of this drive mechanism 4 can stably and accurately control the raising and lowering of the water baffle plate 3, ensuring the effect of water jet flushing.

[0046] Air pump 5 is fixedly installed on water storage tank 1. The air outlet pipe of air pump 5 is used to blow away sediment. Air pump 5 can be a vortex air pump, which has the characteristics of high pressure and large flow rate, and can effectively blow away sediment. When air pump 5 is working, it sprays airflow into the sediment through the air outlet pipe, loosening the sediment and making it easier for water to wash away, thus helping to improve the sediment flushing efficiency.

[0047] The equipment also includes a hydraulic pump 11, hydraulic pipes 12, and four hydraulic lifting rods 13. The four hydraulic lifting rods 13 are respectively installed at the four corners of the water storage tank 1. The hydraulic pump 11 is connected to the four hydraulic lifting rods 13 through the hydraulic pipes 12. The extension and retraction of the hydraulic lifting rods 13 drive the water storage tank 1 to rise and fall. The hydraulic pump 11 provides power to the hydraulic lifting rods 13. By controlling the operation of the hydraulic pump 11, the height of the water storage tank 1 can be adjusted to adapt to open channels of different water depths, ensuring that the equipment can work normally under different operating conditions.

[0048] The equipment also includes a control circuit, which includes a power supply 14, a first switch 15, a second switch 16, a sliding rheostat 17, a gate lifting switch 18, a gate lowering switch 19, a first electromagnet 20, a second electromagnet 21, a third electromagnet 22, a fourth electromagnet 23, a first double-control spring switch 24, and a second double-control spring switch 25.

[0049] The power supply 14, the first switch 15 and the water pump 2 are connected in series. The first switch 15 can control the start and stop of the water pump 2.

[0050] The power supply 14, the second switch 16, the sliding rheostat 17 and the air pump 5 are connected in series. The second switch 16 controls the start and stop of the air pump 5, and the sliding rheostat 17 can adjust the power of the air pump 5.

[0051] Power supply 14, gate lifting switch 18, first electromagnet 20 and fourth electromagnet 23 are connected in series; power supply 14, gate lowering switch 19, second electromagnet 21 and third electromagnet 22 are connected in series.

[0052] The first double-control spring switch 24 is installed between the first electromagnet 20 and the second electromagnet 21, and the second double-control spring switch 25 is installed between the third electromagnet 22 and the fourth electromagnet 23.

[0053] The power supply 14, the moving contact of the first double-control switch, the first stationary contact of the first double-control switch, the first connector of the motor 7, the motor 7, the second connector of the motor 7, the second stationary contact of the second double-control switch, and the moving contact of the second double-control switch are connected in series.

[0054] The power supply 14, the moving contact of the first double-control switch, the second stationary contact of the first double-control switch, the second connector of the motor 7, the motor 7, the first connector of the motor 7, the first stationary contact of the second double-control switch, and the moving contact of the second double-control switch are connected in series.

[0055] By using these switches and electromagnets, the forward and reverse rotation of the motor 7 can be controlled, thereby raising and lowering the water baffle plate 3, accurately controlling the operation of each component, and improving the automation level of the equipment.

[0056] In this embodiment, closing the gate lifting switch 18 can activate the first electromagnet 20 and the fourth electromagnet 23, connecting the moving contact of the first double-control switch with the first stationary contact of the first double-control switch, and connecting the moving contact of the second double-control switch and the second stationary contact of the second double-control switch in series. This connects the circuit of the power supply 14, the moving contact of the first double-control switch, the first stationary contact of the first double-control switch, the first connector of the motor 7, the motor 7, the second connector of the motor 7, the second stationary contact of the second double-control switch, and the moving contact of the second double-control switch. The forward rotation of the motor 7 causes the valve plate to lift.

[0057] Closing the gate lowering switch 19 can activate the second electromagnet 21 and the third electromagnet 22, connecting the moving contact of the first double-control switch with the second stationary contact of the first double-control switch, and connecting the moving contact of the second double-control switch and the first stationary contact of the second double-control switch in series. This connects the circuit of the power supply 14, the moving contact of the first double-control switch, the second stationary contact of the first double-control switch, the second connector of the motor 7, the motor 7, the first connector of the motor 7, the first stationary contact of the second double-control switch, and the moving contact of the second double-control switch. The motor 7 reverses, causing the valve plate to descend.

[0058] The equipment also includes a nested axle 28 and traveling wheels 29. The nested axle 28 is rotatably mounted on the bottom of the water storage tank 1. The nested axle 28 is hollow, and the axle of the traveling wheel 29 is inserted into the nested axle 28. The nested axle 28 has several parallel fixing holes 30, and the axle of the traveling wheel 29 has several mounting holes. The fixing holes 30 and mounting holes are spaced equidistant and can be selectively matched. The traveling wheel 29 and the nested axle 28 are detachably and fixedly connected by bolts passing through the fixing holes 30 and corresponding mounting holes. By adjusting the bolts passing through different fixing holes 30 and mounting holes, the installation position of the traveling wheel 29 can be changed to adapt to open channels of different widths, facilitating the movement of the equipment within the open channel.

[0059] The usage procedure of this embodiment is as follows:

[0060] 1. Adjust the installation position of the traveling wheel 29 on the nested wheel axle 28 according to the width of the open channel. Fix the traveling wheel 29 and the nested wheel axle 28 by passing bolts through the appropriate fixing holes 30 and mounting holes. Then lift and move the equipment to the location of the open channel where the silt needs to be cleaned.

[0061] 2. Based on the water depth of the open channel, start the hydraulic pump 11 and control the extension or retraction of the four hydraulic lifting rods 13 through the hydraulic pipe 12 to adjust the water storage tank 1 to a suitable height.

[0062] 3. Close the first switch 15 and start the water pump 2. The water pump 2 draws water from the channel through the inlet and then delivers it to the water storage tank 1 through the outlet for water storage, so as to keep the equipment stable.

[0063] 4. Depending on the amount of mud and sand to be cleaned, operate the gate lifting switch 18 or the gate lowering switch 19. The control circuit, through the cooperation of the electromagnet and the double-control spring switch, causes the motor 7 to rotate in both directions, thereby driving the water baffle plate 3 to rise or fall in the installation groove, adjusting the water flow and achieving water-binding sand flushing.

[0064] 5. Close the second switch 16 and start the air pump 5. Adjust the power of the air pump 5 through the sliding rheostat 17. The air pump 5 sprays airflow into the mud and sand through the air outlet pipe to loosen the mud and sand and make it easier for the water to wash it away.

[0065] 6. After the sand flushing is completed, open the drainage valve 6. The water and sediment in the water storage tank 1 will be guided by the slope to the drainage outlet, and the water and sediment will be discharged.

[0066] 7. Turn off air pump 5 and water pump 2 in sequence, and lift the equipment out of the open channel via lifting ring 26 for storage or transfer to other locations that need cleaning.

[0067] The implementation principle of this embodiment is as follows: This equipment uses a water pump 2 to pump channel water into a storage tank 1 for storage. The drive mechanism 4 controls the raising and lowering of the baffle plate 3 to adjust the water flow, thus achieving the function of water-flushing and sand-washing. An air pump 5 assists in blowing away the silt, making it easier for the silt to be washed away by the water flow. The slope design and drainage valve 6 facilitate silt discharge. The hydraulic lifting rod 13 can adjust the height of the equipment, and the nested axle 28 and traveling wheels 29 facilitate the movement of the equipment in the open channel. The control circuit can precisely control the operation of each component, improving the automation level and cleaning efficiency of the equipment. Compared with traditional dredging methods, it can solve the problem of siltation in small artificial open channels more efficiently and conveniently, reducing costs and labor intensity.
