Description

Technical Field

[0001] The invention relates to the technical field of reservoir desilting, in particular to deep reservoir desilting equipment. Background Art

[0002] A reservoir is generally interpreted as "a water conservancy engineering building that intercepts floods, stores water and regulates water flow, which can be used for irrigation, power generation, flood control and fish farming." It refers to an artificial lake formed by building a dam at the narrow mouth of a ravine or river. After the reservoir is built, it can play a role in flood control, water storage for irrigation, water supply, power generation, fish farming, etc. When cleaning the silt under the reservoir, a Venturi suction disk is generally used. The Venturi effect is named after its discoverer, the Italian physicist Venturi. This effect is manifested in the phenomenon that when the restricted flow passes through a reduced flow section, the flow velocity of the fluid increases, and its flow velocity is inversely proportional to the flow section. According to Bernoulli's principle, the increase in flow velocity is accompanied by a decrease in fluid pressure, which is the common Venturi phenomenon. In layman's terms, this effect refers to the generation of low pressure near a high-speed flowing fluid, thereby producing an adsorption effect. This effect can be used to make a Venturi tube.

[0003] Most of the sludge cleaning devices currently on the market generally use a cleaning vehicle to pull them to the side of the reservoir, and then extend a water pipe into the bottom of the reservoir. This arrangement has the following problems: it is not easy to clean the sludge in the center of the reservoir, and the cleaning pipe is not easy to move after being placed, which is very inconvenient to use.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , the present invention provides a technical solution:

[0027] A deep reservoir silt removal device comprises a frame 1 and a sludge suction plate 2. The sludge suction plate 2 is fixedly connected to the front side of the frame 1. The principle of the sludge suction plate 2 is that when the restricted flow passes through a reduced flow section, the flow velocity of the fluid increases, and the flow velocity is inversely proportional to the flow section. According to Bernoulli's law, the increase in flow velocity is accompanied by a decrease in fluid pressure, which is the common Venturi phenomenon. In layman's terms, this effect refers to the generation of low pressure near a high-speed flowing fluid, thereby generating an adsorption effect. A Venturi tube can be made using this effect to perform adsorption. The lower end face of the frame 1 is fixedly connected to a base 3. The front and rear end faces of the base 3 are fixedly connected to a connecting device 4. The connecting device 4 comprises a fixing frame 401 and a block 402.

The lower end surface of the sliding plate 702 is rotatably connected with a mobile motor 703. This arrangement can make the mobile motor 703 rotate when it rotates, so as to drive the power device 8 to move, which is convenient for the use and storage of the power device 8. The end of the main shaft of the mobile motor 703 is fixedly connected with a threaded rod 704, and the outer side of the threaded rod 704 is spirally connected with a fixed sleeve 705. The fixed sleeve 705 05 are fixedly connected to the outside with evenly distributed connecting rods 706, the other end of the connecting rod 706 is fixedly connected to the fixed shell 701, the lower end surface of the threaded rod 704 is fixedly connected to the power device 8, the power device 8 includes a rotating cylinder 801 and a fixed ring 802, the rotating cylinder 801 is fixedly connected to the inside with a fixed ring 802, the fixed ring 802 serves to fix the power motor 805, the fixed ring 802 is fixedly connected to the inside with a power motor 805, the end of the main shaft of the power motor 805 is fixedly connected with a paddle 803, this arrangement allows the device to move in the reservoir, making it convenient to clean the silt at the bottom of the central reservoir and expand the scope of use, the rotating cylinder 801 is fixedly connected to the two ends with filter plates 804, the outside of the filter plates 804 are arc-shaped,This arrangement can filter large impurities in the reservoir, and impurities are not easy to accumulate on its surface, ensuring its normal operation. The lower end surface of the lifting device 7 is rotatably connected to the power device 8, and the outside of the power device 8 is provided with evenly distributed emergency stop devices 9. The outside of the emergency stop device 9 is fixedly connected to the base 3. The emergency stop device 9 includes a fixed frame 901 and a rotating motor 902. The outside of the fixed frame 901 is fixedly connected to the base 3, and the inside of the fixed frame 901 is fixedly connected to the rotating motor 902. The end of the main shaft of the rotating motor 902 is fixedly connected to a connecting shaft 906. The rotating motor 902 provides power for the rotation of the emergency stop blade 907. The outside of the connecting shaft 906 is fixedly connected to a driving gear 903, and the outside of the driving gear 903 is meshed with a transition gear 9 04, the outer side of the transition gear 904 is meshed with a driven gear 905, the interior of the driven gear 905 is fixedly connected with a connecting shaft 906, the interior of the transition gear 904 is fixedly connected with a connecting shaft 906, one end of the connecting shaft 906 inside the driven gear 905 and the connecting shaft 906 inside the driving gear 903 are fixedly connected with an emergency stop blade 907, the other end of the connecting shaft 906 inside the driven gear 905 is rotatably connected to the fixed frame 901, and both ends of the connecting shaft 906 inside the transition gear 904 are rotatably connected to the fixed frame 901. This setting ensures the normal use of the device, and the setting of the transition gear 904 ensures that its emergency stop blade 907 rotates in one direction, thereby achieving a good purpose of water flow offset. ,

[0028] Working process: when in use, the power is turned on. When the sludge at the bottom of the reservoir needs to be cleaned, the Venturi suction plate is connected to the external pipeline. At this time, by starting the power device 8, the power motor 805 rotates to drive the paddle 803 to rotate, so that the device can be driven to move to the center of the reservoir, and then the pipeline can perform the sludge suction and cleaning work. The setting of the filter plate 804 ensures that the power device 8 is not interfered by external debris. When it moves to a fixed position, it cannot stop in time. At this time, the emergency stop device 9 in the pushing direction of the power device 8 is started, and its rotating motor 902 drives the emergency stop paddle 907. The emergency stop paddle 907 drives the water flow to offset the water flow driven by the power device 8, thereby ensuring that the device can stop moving, and the driving gear 90 is set 3 and the driven gear 905 can drive the multiple emergency stop blades 907 to rotate, and the transition gear 904 ensures that the emergency stop blades 907 rotate in one direction, and the buoy 5 ensures that the equipment can float on the water surface, and because the buoyancy of the water is upward, the buoy 5 will not be separated from the base 3, and the upper part of the connecting plate 6 is engaged with the fixing frame 401 through the clamping plate 406 to achieve its connection purpose, and the clamping block 402 is engaged with the clamping plate 406 to achieve the fixing effect, and the telescopic spring 404 can push the sliding plate 403 to move, so that the clamping plate 406 is not easily separated from the fixing frame 401. When it needs to be disassembled, by pulling the pulling plate 405, the sliding plate 403 squeezes the telescopic spring 404, thereby achieving the separation purpose, facilitating its transportation, and facilitating the replacement of the buoy 5.

[0029] Embodiment 2:

[0030] In Example 2, the same parts as Example 1 are not repeated. The difference is that when the device is finished working, by starting the lifting device 7, the mobile motor 703 inside it rotates, thereby driving the threaded rod 704 to move, so that its power device 8 can be moved downward while it can be rotated, thereby facilitating the change of the direction of the device. After use, it is reversed so that under the action of the fixing sleeve 705, its threaded rod 704 moves upward, thereby causing the mobile motor 703 to rotate, and the sliding plate 702 is driven upward above the rotating motor 703, so that the power device 8 is stored inside the base 3, which is convenient for its stable placement and avoids its tilting, and has good practical value.
