[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0023] Example 1, as Figure 1 and Figure 2 shown, a filtering device for the water intake of a raw water filtering water intake pump station includes an outer shell one 1, a reinforcing plate 2 is fixedly connected to the outer surface of the outer shell one 1, an outer shell two 5 is fixedly connected to the left part of the upper end of the outer shell one 1, and a filter assembly 3 and a cleaning assembly 4 are arranged on the inner surface of the outer shell one 1.

[0024] In the process of implementation of this embodiment, the first housing 1 and the second housing 5 are placed in the water area of raw water. During the process of the pump station extracting raw water, the filtering component 3 will perform multi-stage filtering on the debris in the raw water, and perform a chemical dosing operation on the filtered water. At the same time, the cleaning component 4 will effectively clean the filtered impurities.

[0025] Specifically, in order to achieve multi-stage filtering of raw water, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 , in this embodiment, the filtering component 3 includes a first fixing plate 31 fixedly connected to the inner surface of the first housing 1. The inner surface of the first housing 1 is provided with a suction mechanism 32. The inner surface of the first fixing plate 31 is provided with a first filtering mechanism 33. The inner surface of the first filtering mechanism 33 is provided with a floating mechanism 34. The inner surfaces of the first housing 1 and the second housing 5 are jointly provided with a chemical dosing mechanism 35. The outer surface of the suction mechanism 32 is provided with a knocking mechanism 36. The inner surface of the first housing 1 is provided with a second filtering mechanism 37.

[0026] Furthermore, refer to Figure 3 and Figure 4 , in this embodiment, the suction mechanism 32 includes two turbine housings 321 fixedly connected to the inner surface of the first housing 1. The inner surfaces of the two turbine housings 321 are both rotatably connected with turbine rods 322. The inner surfaces of the two turbine housings 321 are both fixedly connected with a first connecting pipe 323. The inner surfaces of the two turbine housings 321 are jointly fixedly connected with a second connecting pipe 324 fixedly connected to the first housing 1. A first solenoid valve 326 is fixedly installed on the outer surface of the second connecting pipe 324. A pump 325 is fixedly installed at the left end of the second connecting pipe 324.

[0027] During the implementation process, when the pump station extracts raw water, at this time, the pump 325 is started, so that the pump 325 generates suction in the second connecting pipe 324, and the water in the first housing 1 is introduced into the turbine housing 321 through the first connecting pipe 323. Under the impact of the water flow, the turbine rod 322 can rotate.

[0028] Secondly, the flow direction of the water is controlled by the first solenoid valve 326, so that the turbine rods 322 in the two turbine housings 321 can rotate independently.

[0029] The above-mentioned turbine rod 322 and turbine housing 321 both belong to mature technical means and conventional technical designs in the prior art, and will not be elaborated in this solution.

[0030] Furthermore, refer to Figure 3 and Figure 6, in this embodiment, the floating mechanism 34 includes a first connecting pipe 341 fixedly connected to the inner surface of the hemispherical net 333 and the outer shell 1. The outer surface of the first connecting pipe 341 is slidably connected to a second connecting pipe 342. The upper end of the second connecting pipe 342 is fixedly connected to a leakage hole block 343. The outer surface of the leakage hole block 343 is fixedly connected to an airbag 344. The inner surface of the first connecting pipe 341 is fixedly installed with a second solenoid valve 345.

[0031] During the implementation process, when the outer shell 1 is placed in the set water area, the leakage hole block 343 on the second connecting pipe 342 can always float with the buoyancy provided by the airbag 344. A part of the leakage hole block 343 floats on the water surface, and the other part is always below the water surface. It can follow the change of the water level, maintain a stable water inflow, effectively cope with the water level fluctuation, ensure the water flow stability during the filtration process, provide a continuous and balanced water source for the subsequent filtration operation, ensure the efficient operation of the water intake pump station, improve the overall filtration effect and reduce the problem of unstable water intake caused by the water level change.

[0032] Secondly, the second solenoid valve 345 can control whether the device intakes water.

[0033] Further, refer to Figure 3 and Figure 5 , in this embodiment, the first filtration mechanism 33 includes a hemispherical net 333 fixedly connected to the inner surface of the first fixing plate 31. The inner surface of the hemispherical net 333 is fixedly connected to a second fixing plate 331. The upper end of the second fixing plate 331 is rotatably connected to a hemispherical block 332. The inner surface of the hemispherical block 332 is fixedly connected to a round rod 334 fixedly connected to the upper end of the turbine rod 322 located on the right. The inner surface of the first fixing plate 31 is fixedly connected to a third connecting pipe 335.

[0034] Further, refer to Figure 3 and Figure 9 , in this embodiment, the second filtration mechanism 37 includes an inclined plate 371 fixedly connected to the left and right parts of the inner surface of the outer shell 1. The inner surface of the inclined plate 371 is fixedly connected to a corrugated plate 372. The upper end of the inclined plate 371 is fixedly connected to a plurality of blocking plates 374. A plurality of filtration holes 373 are opened at the upper end of the inclined plate 371.

[0035] During the implementation process, the water entering through the floating mechanism 34 will flow into the space formed by the hemispherical net 333 and the hemispherical block 332. Since the outer surface of the hemispherical block 332 is an arc surface, the water can be evenly distributed on the outer surface of the hemispherical block 332. The solenoid valve one 326 controls the flow direction of the water, causing the turbine rod 322 on the right to rotate. During the rotation process, the hemispherical block 332 is driven to rotate, and the partition plate on the hemispherical block 332 can drive the raw water to sputter and impact against the inner surface of the hemispherical net 333. As a result, the large particles in the water can be retained on the inner surface of the hemispherical net 333 under the action of the counter-impact. The water after preliminary filtration will fall on the upper end of the fixed plate one 31 through the hemispherical net 333 and, under the action of gravity, fall on the inclined plate 371 and the corrugated plate 372 through the connecting pipe three 335. At this time, the water will be in the groove at the intersection of the inclined plate 371 and the corrugated plate 372. As the water continuously increases, the water will flow to the right and, during the flowing process, pass through the filter holes 373 in sequence. The filter holes 373 can filter the sundries one by one according to the aperture size. The filtered impurities will be retained in the space formed by the inclined plate 371 and the blocking plate 374. The large particles are initially filtered out by the counter-impact, ensuring that the impurities are retained on the inner surface of the filter net. The filtered water flows step by step under the action of gravity, passes through the intersection area of the inclined plate 371 and the corrugated plate 372, and is gradually filtered through the filter holes 373 with different apertures. The impurities are separated by size and retained in a specific space, which can effectively remove the impurities in the water, achieve a higher filtration accuracy through step-by-step filtration, reduce the blockage of the filter net through the counter-impact mechanism, improve the filtration efficiency and the reliability of the device, and realize multiple filtration operations on one filter plate, reducing the use cost and maintenance.

[0036] Secondly, after multi-stage filtration, the water will enter the bottom of the outer shell one 1 through the concave holes on the inclined plate 371.

[0037] The aperture of the above-mentioned filter holes 373 gradually becomes smaller along the inclined direction, and at the same time, the aperture of the filter holes 373 at the same position is the same.

[0038] Embodiment 2. Specifically, in order to remove the particulate calcium chloride in the filtered water, refer to Figure 3 and Figure 7 In this embodiment, the dosing mechanism 35 includes a circular cover 351 fixedly connected to the inner surface of the outer shell one 1. A screw rod 352 is rotatably connected to the inner surface of the circular cover 351. A gear set one 353 is fixedly connected to the outer surfaces of the turbine rod 322 on the right and the screw rod 352. A hopper 355 is fixedly installed on the inner surface of the outer shell two 5. A communicating pipe three 354 is fixedly connected to the inner surfaces of the hopper 355 and the circular cover 351.

[0039] Furthermore, refer to Figure 3 andFigure 8 In this embodiment, the knocking mechanism 36 includes a fixed rod 361 fixedly connected to the outer surface of the right turbine rod 322. A spherical rod 362 is rotatably connected to the inner surface of the fixed rod 361. A spring piece 363 is fixedly connected to the front ends of both the fixed rod 361 and the spherical rod 362.

[0040] During the implementation process, when the right turbine rod 322 rotates, it drives the screw rod 352 to rotate in the circular cover 351 under the transmission of the first gear set 353. Then, the granular calcium chloride in the hopper 355 falls into the inner cavity of the circular cover 351 through the third connecting pipe 354. Under the action of the extrusion and screw conveying, the granular calcium chloride falls through the pipeline to the bottom of the first housing 1 and is mixed with the filtered water to disinfect the purified water.

[0041] Secondly, when the right turbine rod 322 rotates, it drives the spherical rod 362 on the fixed rod 361 to rotate. At the same time, the third connecting pipe 354 is within the rotation range of the spherical rod 362. So that when the spherical rod 362 rotates, it knocks and vibrates the third connecting pipe 354 through the deformation force of the spring piece 363, preventing blockage of the third connecting pipe 354 and the hopper 355, realizing the automatic feeding and mixing of granular calcium chloride, and thus effectively improving the purification effect of water quality.

[0042] The above-mentioned screw rod 352 and circular cover 351 constitute a screw conveyor in the prior art.

[0043] The above-mentioned hopper 355 is a mature technical means and equipment in the prior art. In this solution, it meets the requirements that its top can be opened and it has good sealing performance.

[0044] Embodiment 3. Specifically, in order to clean the debris after multi-stage filtration, refer to Figure 3 、 Figure 10 、 Figure 11 and Figure 12 In this embodiment, the cleaning assembly 4 includes a chute plate 41 fixedly connected to the front part of the inner surface of the first housing 1. A cleaning mechanism 42 is arranged on the inner surface of the chute plate 41. A scraping mechanism 43 is arranged on the outer surface of the round rod 334. A first collection frame 44 is fixedly installed in the inner cavity of the second housing 5. A second collection frame 45 is fixedly installed on the inner surface of the first housing 1.

[0045] Furthermore, refer to Figure 11 In this embodiment, the scraping mechanism 43 includes two arc-shaped plates 431 fixedly connected to the outer surface of the round rod 334. The upper end of the second fixing plate 331 penetrates through and extends to the left end of the first housing 1 and is fixedly connected to a fourth connecting pipe 432. An electromagnetic valve three 433 is fixedly installed on the inner surface of the fourth connecting pipe 432.

[0046] During implementation, as the round rod 334 rotates, it drives the arc-shaped plate 431 to rotate and scrape on the inner surface of the hemispherical net 333, enabling the arc-shaped plate 431 to clean the large particle debris that has stayed, preventing the hemispherical net 333 from being blocked. The debris cleaned will fall on the upper end of the second fixing plate 331. By activating the third solenoid valve 433, the debris can fall into the fourth connecting pipe 432 under the rotational action of the arc-shaped plate 431 and finally reach the first collection box 44.

[0047] The above-mentioned first solenoid valve 326, second solenoid valve 345, and third solenoid valve 433 are all mature control technology means and devices in the prior art, and the internal structure, principle, and connection method thereof will not be elaborated in this solution.

[0048] Further, referring to Figure 3 and Figure 10 , in this embodiment, the cleaning mechanism 42 includes a reciprocating rod 421 slidably connected to the inner surface of the chute plate 41. A scraper 423 slidably connected to the outer surface of the reciprocating rod 421 is also slidably connected to the inner surface of the chute plate 41. A second gear set 422 is fixedly connected to the outer surfaces of the left turbine rod 322 and the reciprocating rod 421. Two spring telescopic rods 424 are fixedly connected to the front part of the inner surface of the first housing 1, and a placement plate 425 is fixedly connected to the rear ends of the two spring telescopic rods 424 together.

[0049] During implementation, when it is necessary to clean the debris staying on the second filtering mechanism 37, through the control of the first solenoid valve 326 at this time, the pumped water enters the turbine housing 321 on the left, driving the left turbine rod 322 to rotate. Under the transmission of the second gear set 422, the reciprocating rod 421 is driven to rotate. Since the reciprocating rod 421 and the scraper 423 are slidably connected, the scraper 423 can slide on the inner surface of the chute plate 41 and clean the debris staying on the inclined plate 371 and the corrugated plate 372. When the scraper 423 moves forward, the convex block at the front end will push the placement plate 425 forward, causing the spring telescopic rod 424 to be in a compressed state. Subsequently, the cleaned debris will be directly pushed into the second collection box 45, automatically and efficiently cleaning the staying large particle debris, preventing the filter screen from being blocked, ensuring the stability of the filtering efficiency, collecting and discharging the cleaned debris centrally, and reducing the frequency of manual cleaning and maintenance costs.

[0050] The above-mentioned reciprocating rod 421 and scraper 423 constitute a ball screw mechanism in the prior art.

[0051] The above-mentioned first gear set 353 and second gear set 422 are both composed of two bevel gears.

[0052] Workflow: During use, stable water inlet is achieved through the floating mechanism 34, and the raw water undergoes multi-stage filtration under the action of the first filtration mechanism 33 and the second filtration mechanism 37. Subsequently, during the suction process by the suction mechanism 32, the dosing mechanism 35 and the knocking mechanism 36 can add drugs to the filtered water for disinfection operations, and the cleaning mechanism 42 and the scraping mechanism 43 can automatically clean the debris filtered out.

[0053] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
