Description

Technical Field

[0001] This invention relates to the field of water pumps, and more specifically to a water pump. Background Technology

[0002] Application number 202010056187.2 describes an anti-clogging water pump. The device utilizes a main filter plate and a secondary filter plate to filter the passing water flow. The main filter plate blocks larger debris, while the secondary filter plate filters smaller debris, achieving optimal debris blocking. When cleaning is needed after a period of use, the pipe cover can be opened directly, allowing the debris to be flushed out with the water flow. For adhesive debris, the adjusting rod can be rotated using an adjuster, which in turn drives two debris removers to slide inwards via a pusher, allowing the debris to be discharged with the water flow. The entire process is convenient and quick, and easy to operate. However, this water pump is not convenient for cleaning residual debris on the water pipes, which can easily lead to pipe blockage. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a water pump, which has the beneficial effect of cleaning the inner wall of the water pipe and preventing the water pipe from becoming blocked.

[0005] A water pump includes a water pump, a chamber connected to the lower end of the water pump, connecting pipes to both ends of the chamber, an inlet pipe installed at the lower end of the chamber, an outlet pipe connected to each of the two connecting pipes, and filter discs I slidably connected to the inner sides of the two connecting pipes, with the two filter discs I located inside the two outlet pipes respectively.

[0006] Both connecting pipes have spiral grooves on their inner sides, and both filter discs I have protrusions integrally formed on their circumferential surfaces. The protrusions on both sides are slidably connected in the corresponding spiral grooves. Both filter discs I have sleeves rotatably connected to them, and the two sleeves are respectively sealed and inserted into the two ends of the connecting pipes.

[0007] Both filter discs I are fixedly surrounded by multiple scraping teeth.

[0008] Both sleeve rods are sealed with core rods, and the inner ends of the two core rods are rotatably connected to filter discs II. The two filter discs II are slidably connected in the two connecting pipes, and the two filter discs II are respectively attached to the two filter discs I. The scraper teeth are inserted into the corresponding filter discs II.

[0009] The lower end of the chamber has a slot, and a collection box is detachably and sealed at the slot. The water inlet pipe is connected to the lower end of the collection box. Attached Figure Description

Detailed Implementation

[0024] like Figures 1 to 3 As shown:

[0025] A water pump includes a water pump 101, a chamber 102 connected to the lower end of the water pump 101, and connecting pipes 103 connected to both ends of the chamber 102. The water pump 101 is characterized in that an inlet pipe is installed at the lower end of the chamber 102, an outlet pipe is connected to each of the two connecting pipes 103, and a filter disc I 201 is slidably connected to the inner side of each of the two connecting pipes 103. The two filter discs I 201 are respectively located inside the two outlet pipes.

[0026] When the water pump 101 starts, water enters the chamber 102 through the inlet pipe and flows out through the outlet pipes on both sides. Since the two filter discs I201 are located inside the two outlet pipes respectively, the two filter discs I201 filter the water flow as it flows to the outlet pipes on both sides. When not in use, the two filter discs I201 can slide within the two connecting pipes 103, thereby scraping off the debris adhering to the connecting pipes 103 and cleaning the inner walls of the two connecting pipes 103 to prevent blockage. Driven by the water pump 101, water is pumped in and discharged through the two outlet pipes, which can direct the water flow in two directions and filter and prevent blockage of the water flowing in both directions.

[0027] like Figures 2 to 3 As shown:

[0028] The inner sides of both connecting pipes 103 are provided with spiral grooves 104, and the circumferential surfaces of both filter discs I 201 are integrally formed with protrusions 202. The protrusions 202 on both sides are slidably connected in the corresponding spiral grooves 104. The two filter discs I 201 are rotatably connected with sleeves 204, and the two sleeves 204 are respectively sealed and inserted into the two ends of the connecting pipes 103.

[0029] When the sleeve rod 204 is pushed, the sleeve rod 204 drives the filter disc I 201 to slide inside the connecting pipe 103. When the filter disc I 201 slides inside the connecting pipe 103, it drives the protrusion 202 to slide back and forth synchronously. Since the protrusion 202 is slidably connected inside the spiral groove 104, when the filter disc I 201 slides back and forth, the cooperation between the protrusion 202 and the spiral groove 104 will drive the filter disc I 201 to rotate back and forth. This allows the filter disc I 201 to rotate while sliding back and forth inside the connecting pipe 103, so that the rotational force of the filter disc I 201 in the circumferential direction can further scrape off the impurities on the inner wall of the connecting pipe 103, increasing the cleaning effect on the inner wall of the connecting pipe 103.

[0030] like Figure 3 As shown:

[0031] Multiple scraper teeth 203 are fixedly attached around both filter discs I 201;

[0032] The filter disc I 201 synchronously drives the multiple scraper teeth 203 on it to reciprocate and rotate, so that the scraper teeth 203 can further rotate and scrape away the impurities on the inner wall of the connecting pipe 103, increasing the effect of scraping away impurities and debris on the inner wall of the connecting pipe 103. Secondly, for filamentous debris, the rotating multiple scraper teeth 203 can wrap the filamentous debris around the multiple scraper teeth 203 while scraping away the debris, preventing the filamentous debris from flowing into the outlet pipe through the filter holes on the filter disc I 201.

[0033] like Figures 4 to 6 As shown:

[0034] Both sleeve rods 204 are sealed with core rods 206, and the inner ends of the two core rods 206 are rotatably connected to filter discs II 205. The two filter discs II 205 are slidably connected in the two connecting pipes 103 respectively, and the two filter discs II 205 are respectively attached to the two filter discs I 201. The scraper teeth 203 are inserted into the corresponding filter discs II 205.

[0035] Under normal conditions, filter disc II 205 is attached to filter disc I 201. Pushing the core rod 206 inward causes filter disc II 205 to move away from filter disc I 201, so that filter disc II 205 can scrape off the debris and the filaments wrapped on the multiple scraper teeth 203, thereby cleaning the multiple scraper teeth 203.

[0036] like Figure 7 As shown:

[0037] The lower end of the chamber 102 is provided with a slot, and a collection box 108 is detachably and sealed at the lower end slot of the chamber 102. The water inlet pipe is connected to the lower end of the collection box 108.

[0038] Two filter discs I 201 and II 205 filter the water flow. The filtered debris is retained in the two connecting pipes 103. Filter disc I 201 drives filter disc II 205 to move synchronously to scrape off the impurities in the connecting pipes 103. The scraped debris is pushed inward into the collection box 108. The collection box 108 can be removed to clean off the scraped debris in time, thereby avoiding blockage inside the water pump.

[0039] Secondly, when the two filter discs I 201 filter the water flow, impurities are preferentially blocked by filter disc II 205, thus preventing filter disc I 201 from becoming clogged. When the two sleeve rods 204 drive the two filter discs I 201 to move inward, the impurities are pushed towards the middle. Then, the two core rods 206 are controlled to move towards each other, and the two core rods 206 drive the two filter discs II 205 to move towards each other, pushing the blocked garbage into the collection box 108. At the same time, the impurities scraped off from the multiple scraper teeth 203 also fall into the collection box 108 for collection.

[0040] likeFigure 7 As shown:

[0041] A base plate 109 is fixedly connected to the collection box 108. A guide rod 106 is slidably connected to the base plate 109. A fixing frame 105 is fixedly connected to the guide rod 106. The fixing frame 105 is fixedly connected to the chamber 102. A reduction motor is fixedly connected to the chamber 102. The output shaft of the reduction motor is connected to a lead screw I 107 through a coupling. The lead screw I 107 is threadedly connected to the base plate 109.

[0042] Under normal conditions, the collection box 108 is attached to the bottom surface of the chamber 102, and a sealing gasket is provided at the contact point between the collection box 108 and the chamber 102. When the geared motor starts, it drives the lead screw I 107 to rotate. The lead screw I 107 drives the base plate 109 to move downward, and the base plate 109 drives the collection box 108 to move downward. The collection box 108 moves downward and opens, which facilitates the cleaning of the garbage in the collection box 108, thereby realizing the timely cleaning of the water pump with filtration function and avoiding excessive accumulation of impurities that may cause blockage.

[0043] like Figures 8 to 9 As shown:

[0044] The collection box 108 is sealed with a bracket 302, and two scrapers 303 are symmetrically fixed to the upper end of the bracket 302. The scrapers 303 are located at the upper end of the filter disc II 205.

[0045] When the two filter discs I 201 move inwards and then the two filter discs II 205 also move inwards, the waste is pushed into the collection box 108. At this time, the control bracket 302 moves downwards, and the bracket 302 drives the two scrapers 303 to move downwards. The two scrapers 303 scrape the opposite surfaces of the two filter discs II 205, thereby scraping away the dirt remaining on the two filter discs II 205. The two scrapers 303 are also equipped with bristles to further clean the impurities on the two filter discs II 205, preventing the two filter discs II 205 from becoming clogged.

[0046] like Figure 9 As shown:

[0047] Two pads are symmetrically fixed inside the collection box 108, and a filter box 305 is placed on the two pads. The filter box 305 corresponds to the slot and its upper end rests on the bottom surface of the chamber 102. The insert 302 is slidably connected to the filter box 305.

[0048] The upper end of the filter box 305 rests against the chamber 102, and the lower end of the filter box 305 rests against the pad. There is a certain space between the bottom surface of the filter box 305 and the bottom surface of the collection box 108, so that the filter box 305 can perform initial filtration on the water flowing in from the inlet pipe. The filtered debris remains in the space between the filter box 305 and the collection box 108. When cleaning the debris in the connecting pipe 103, the scraped debris will also be received by the filter box 305. In this way, when the collection box 108 is opened, the debris in the filter box 305 can be cleaned. By sliding the filter box 305 upward, the debris in the collection box 108 can be cleaned.

[0049] like Figures 7 to 8 As shown:

[0050] A vertical frame 301 is fixedly connected to the insert 302. The vertical frame 301 is inserted into the base plate 109. A lead screw II 304 is threadedly connected to the base plate 109. A servo motor is fixedly connected to the base plate 109. The output shaft of the servo motor is connected to the lead screw II 304 through a coupling.

[0051] The servo motor starts and drives the lead screw II 304 to rotate. The lead screw II 304 drives the vertical frame 301 to move downward. The vertical frame 301 drives the two scrapers 303 to move downward through the insert 302. The two scrapers 303 scrape and clean the opposite surfaces of the two filter discs II 205 that are moving in opposite directions, so as to avoid the filter discs II 205 from clogging to the greatest extent.

[0052] like Figure 6 As shown:

[0053] A dual-axis motor is fixedly connected to the fixed frame 105. The output shafts on both sides of the dual-axis motor are respectively connected to screws 208 via couplings. Side frames 207 are threadedly connected to the two screws 208 respectively. The two side frames 207 are respectively fixedly connected to the two sleeve rods 204. Electric push rods are fixedly connected to the two side frames 207. The telescopic ends of the two electric push rods are respectively fixedly connected to the two core rods 206.

[0054] The dual-axis motor starts and drives the two screws 208 to rotate. The two screws 208 drive the two side frames 207 to slide towards or away from each other, thereby driving the two filter discs I 201 to move towards or away from each other through the two sleeve rods 204, thus cleaning the two connecting pipes 103. When the two electric push rods start, they drive the two filter discs II 205 to move closer to or further away from the filter discs I 201, thereby cleaning the scraper teeth 203, and cleaning the filter discs II 205 themselves through the scraper 303.
