Description

Technical Field

[0001] The present invention relates to the technical field of vertical water pumps, and more particularly to a vertical water pump dredging device. Background Art

[0002] Vertical pumps are used to transport abrasive, coarse-grained, and high-concentration slurry, without the need for any shaft seals and shaft seal water, and can also operate normally under conditions of insufficient suction. The slurry actually refers to an object formed by mixing water or other types of liquids with some solids that are insoluble in the liquid.

[0003] In the current field of vertical water pump dredging devices, such as the device with the publication number CN222376823U, it has a load-bearing transmission mechanism, a high-frequency vibration mechanism, and a vertical water pump. Its load-bearing transmission mechanism includes parts such as a transmission component, a traction member, an outer frame, and a guide rod. This device holds the vertical water pump suspended and makes it inclined for high-frequency vibration, and shakes off impurities on the inner wall of the water pump through high-frequency vibration, solving to a certain extent the problem of inner wall corrosion caused by traditional water flushing. However, such devices have significant defects in the automation and continuity of dredging operations: they only rely on a single connecting pipe for medium output. When it is necessary to clean the output pipeline, it is necessary to stop the machine and switch the pipeline, resulting in the interruption of the dredging operation and unable to meet the efficient requirements of multi-channel and multi-pipeline collaborative work.

[0004] In the prior art, although the automatic cut-off and opening of pipelines can be achieved through conventional devices such as solenoid valves, in the actual application scenarios of dredging devices, such solutions have fundamental deficiencies: Poor adaptability to harsh working conditions: During the dredging process, the medium contains high-concentration sediment and impurities, and the solenoid valve spool is prone to jamming and failure, and the electromagnetic components have low reliability in humid and vibrating environments, unable to ensure long-term stable operation; Insufficient functional integration: The existing solutions can only achieve single pipeline on-off control, and cannot integrate the functions of water transportation and dredging, pipeline cleaning, and sewage discharge, resulting in the need for the device to be equipped with independent cleaning pipelines and power sources, with redundant structures and high energy consumption.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The conversion mechanism provided by the present invention uses a first gear and a first sliding tooth plate, a second gear and a second sliding tooth plate, and a third threaded rod to drive the opening and closing plate. The conversion mechanism adopts a pure mechanical transmission structure, and realizes the reliable opening and closing of the opening and closing plate through mechanical hard connection. Without electronic components, it is shock-resistant and pollution-resistant, avoiding the jamming of solenoid valves in high-impurity environments. Through mechanical linkage, the accurate switching of the water outlet pipe, the first connecting pipe, the second connecting pipe, and the third connecting pipe is realized, and through the rigid cooperation of the sliding tooth plate and the opening and closing plate, combined with the physical seal of the duckbill valve, it is shock-resistant and pollution-resistant, suitable for harsh working conditions, and is irreplaceable by solenoid valves.

[0017] Through the cooperation of the duckbill valve and the sealing plate, the present invention enables the automatic switching between the cleaning pipe and the sewage pipe in different modes without additional sensors or control systems. The conversion mechanism provided by the present invention does not simply realize the on-off of the pipeline, but through the linkage of the third servo motor driving the turbine blade, the duckbill valve and the sealing plate, integrates the three functions of "water flow-driven rotation", "cleaning liquid circulation", and "sewage cutoff" into the same connection box, forming a closed-loop system of "water conveyance, cleaning, and sewage discharge".

[0018] During normal water conveyance, the turbine blade rotates with the water flow (passive mode), and the duckbill valve seals to prevent water leakage from the cleaning pipe; When switching to the cleaning mode, the fourth servo motor drives the first opening and closing plate to close the main waterway, and the third servo motor actively drives the turbine to accelerate. The high-pressure water flows through the cleaning pipe to flush the inside of the water pump in the reverse direction. At the same time, the sealing plate is pressed to open the sewage pipe to discharge impurities. This mechanical design with multi-mode linkage cannot be achieved by the existing technical solutions of single solenoid valve controlling the on-off of the pipeline, which reflects creativity.

[0019] The connecting shaft provided by the present invention has a hollow structure inside, which cooperates with the duckbill valve and the turbine blade. The water flow is used to drive the turbine to drive the connecting shaft to rotate. At the same time, the automatic switching between the cleaning pipe and the sewage pipe is realized through the spring and the sealing plate. When normal water is conveyed, the duckbill valve seals the connection box, and when cleaning, the high-pressure water flow pushes open the sealing plate for sewage discharge, without additional power sources, solving the energy consumption problem caused by the functional separation in the prior art.

[0020] Based on the flange connection, the present invention realizes quick disassembly and assembly through the engagement of the first sealing block and the second sealing block at the docking position of the water inlet pipe and the conveying pipe, and the inclined surface / arc contour design of the insertion rod and the block. The spring provides continuous pre-tightening force, solving the problem of sealing attenuation caused by vibration in traditional flange connections, especially suitable for the working conditions of water pumps with long-term high-frequency vibration.

[0021] The first servo motor provided by the present invention drives the first threaded rod to adjust the lifting of the threaded slider, and realizes the angular flipping of the splash-proof plate through the limiting groove of the rotating rod. Compared with the fixed splash-proof structure, the protection range can be dynamically adjusted according to the water pump speed and the dredging depth, improving safety and applicability.

[0037] Working principle: As Figures 1 to 12 shown, when the vertical water pump dredging equipment is in use, first, when it is necessary to dredge multiple pipelines and multiple paths simultaneously, the fourth servo motor 1317 is turned on. Through the rotation of the third threaded rod 1318, the first sliding tooth plate 1319 is driven to slide. The sliding of the first sliding tooth plate 1319 drives the first opening and closing plate 1321 to flip along the inner wall of the water outlet pipe 6 through the connection of the first gear 1320, making the water outlet pipe 6 in a closed state. At the same time, the sliding of the first sliding tooth plate 1319 drives the lifting block 1323 to slide through the rotation of the pulling rod. The sliding of the lifting block 1323 drives the second sliding tooth plate 1326 to slide through the rotation of the second pulling rod 1324 and the connection of the first sliding rod 1325. The sliding of the second sliding tooth plate 1326 drives the second opening and closing plate 1328 to flip through the connection of the second gear 1327, making the second connecting pipe 1303 and the third connecting pipe 1304 in an open dredging state; Next, the third servo motor 1305 is turned on. Through the rotation of the driving gear 1306, the connecting gear 1307 is driven to rotate. The rotation of the connecting gear 1307 drives the upper turbine blade 1309 to rotate through the rotation of the connecting shaft 1308. At the same time, under the connection of the cleaning pipe 1316, the duckbill valve 1310 rotates and sprays for cleaning synchronously, automatically rotating and cleaning the impurities in the connection box 1301. Under the action of the upper turbine blade 1309, the impurities are discharged from the connection box 1301. At the same time, when the lower turbine blade 1311 rotates, the water pressure squeezes the sealing plate 1312 and the first spring 1313, making the impurities discharged from the sewage pipe 1314 again, improving the efficiency of self-cleaning and discharging impurities in multiple ways; Next, when the single vertical water pump is placed on the clamping box 3 through the clamping block 11 for clamping and installation, in order to improve the anti-splash effect when the water pump is flipped and dredged by the flipping motor 2, the first servo motor 801 is turned on. Through the rotation of the first threaded rod 802, the threaded slider 803 is driven to slide along the inner wall of the fixed groove 804. Under the sliding of the threaded slider 803 along the inner wall of the limiting groove 806, the rotating rod 805 is driven to flip, and at the same time, the anti-splash plate 807 is driven to flip synchronously, effectively preventing the soil from splashing during the flipping and dredging of the water inlet pipe 5 and the water outlet pipe 6; Finally, when the delivery pipe 7 is butt-connected and installed with the water inlet pipe 5, in order to further improve the sealing effect of the connection between the delivery pipe 7 and the water inlet pipe 5 through flange connection, the first sealing block 1401 and the second sealing block 1402 are butted, and the insertion rod 1403 and the clamping block 1404 are clamped and installed, so that the sealing block is clamped and installed at the connection of the delivery pipe 7 and the water inlet pipe 5, improving the sealing effect during long-term use of the water pump.
