Description

Technical Field

[0001] The invention relates to the technical field of swimming pool water cleaning, in particular to a continuous filtering device for decentralized water outlet of a swimming pool. Background Art

[0002] After long-term use and under the influence of various environmental factors, various impurities will accumulate in the outdoor swimming pool water, such as fallen leaves, insects and residual chemicals. These substances will seriously affect the water quality and swimming environment of the pool and pose a threat to human health. Therefore, the swimming pool water needs to be filtered after a period of use to remove various impurities in the pool water.

[0003] At present, when filtering swimming pool water, the pump body in the filtration system in the swimming pool pumps the pool water into the filter and removes various impurities in the water through the filter. However, the current filtration process has the following problems: 1. After the filter filters the pool water, various impurities remain in the filter. When the amount of various impurities is too large and affects the normal use of the filter, it is necessary to stop the filtration operation and clean the filter. Secondly, impurities are easy to block the filter during the filtration process, affecting the pool water from entering the filter for filtration. The overall filtration efficiency is low and it takes a long time.

[0033] like Figure 1 and Figure 2 As shown, a continuous filtering device for decentralized water discharge of a swimming pool comprises: a filtering pipe 1, wherein the filtering pipe 1 is a pipe with both front and rear ends open, and a sealing door (not shown in the figure) is arranged at the rear end of the filtering pipe 1, a plurality of filtering pipes 1 are arranged equidistantly from left to right and the axes extend from front to back through the inner wall of one side of the swimming pool, a filtering mechanism 2 for filtering pool water in the swimming pool is arranged in the filtering pipe 1, and a collecting unit 3 for collecting impurities in the pool water after filtering is arranged on the filtering pipe 1.

[0041] like Figure 2 As shown, the collecting unit 3 also includes a side plate 33, two side plates 33 symmetrically arranged in an upper and lower direction are fixedly provided on the filtering pipe 1, and the side plate 33 is located between the two storage boxes 31, and a threaded column 330 with an axis extending from left to right is fixedly provided on the side plate 33, and a fixing plate 331 penetrating the threaded column 330 is fixedly provided on the end surface of the storage box 31 facing the side plate 33, and a threaded cap 332 for fixing the fixing plate 331 is provided on the threaded column 330.

[0042] like Figure 7 As shown, an arc-shaped blocking plate 34 is placed in the storage box 31, and a plurality of blocking blocks 340 evenly distributed in the circumferential direction are fixedly sleeved on the blocking plate 34, and the blocking blocks 340 extend from front to rear.

[0043] like Figure 7 and Figure 8As shown, the blocking plate 34 is provided with a plurality of through slots 1 341 extending from front to back in an axial direction, and the blocking block 340 is provided with two through slots 2 342 symmetrically arranged in the front and rear directions.

[0044] like Figure 7 and Figure 8 As shown, a snap-fit ​​group 35 is commonly provided between the obstruction plate 34 and the corresponding storage box 31, and the snap-fit ​​group 35 includes a receiving groove 350. The arc-shaped inner walls of the two storage boxes 31 that are far away from each other are both provided with a convex receiving groove 350, and the small end of the receiving groove 350 is close to the rotating shaft 201. The front and rear end surfaces of the obstruction plate 34 are symmetrically fixed with snap-fit ​​strips 351, and the portion of the snap-fit ​​strip 351 close to the receiving groove 350 is a right-angled triangle section, and the portion away from the receiving groove 350 is an elastic horizontal section.

[0045] like Figure 2 , Figure 3 and Figure 6 As shown, the control group 32 includes a rotating roller 320, and the rotating shaft 201 is fixedly sleeved with a rotating roller 320 located between the fixed circular plate 20 and the fixed bar 213, and the rotating roller 320 is provided with two front-to-back symmetrical circumferential grooves 321, and a control column 323 with an axis from top to bottom slidingly penetrates the filter pipe 1 and cooperates with the rotating roller 320, and the part of the control column 323 located outside the filter pipe 1 is fixedly sleeved with a mounting circular plate 324, and a spring 2 325 is fixedly arranged between the mounting circular plate 324 and the outer ring wall of the filter pipe 1, and a spring 326 is arranged between the rotating roller 320 and the fixed circular plate 20, and the width of the circumferential groove 321 is greater than the diameter of the control column 323.

[0046] During the specific operation, the following steps are included: S1. In the initial state, the annular baffle 206 blocks the corresponding fan-shaped groove 30, that is, the filter pipe 1 and the storage box 31 are in a separated state. Secondly, before performing the filtering operation, the fixing plates 331 on the two storage boxes 31 are sleeved on the corresponding threaded columns 330, and then the threaded caps 332 are tightened so that the two storage boxes 31 are fixed in the corresponding fan-shaped grooves 30. Then, the rear end of the filter pipe 1 is in an open state, and the pool water flows from the back to the front into the filter pipe 1. The pool water contacts the filter screen 204 on the filter plate 202 for filtration, and the impurities in the pool water are isolated in the area between the outer arc surface of the filter screen 204 and the inner ring wall of the filter pipe 1. After the pool water is filtered through the filter screen 204, it flows out from the front side of the filter pipe 1.

[0047] During the flow of pool water in the filter pipe 1, the water flow causes the driving blade 220 to drive the fixed circular sleeve 22 to rotate synchronously, and the fixed circular sleeve 22 drives the rotating shaft 201 to rotate forward. The rotating shaft 201 rotates through the filter plate 202 to drive the filter screen 204 to rotate synchronously, so that the filter screen 204 forms a dynamic filtering mode, which improves the filtering efficiency of the filter screen 204 for the pool water. Secondly, when the amount of pool water is small or the flow speed of the pool water is slow, it is difficult for the driving blade 220 to drive the fixed circular sleeve 22 to rotate through the flow of pool water, and then the external motor is driven to drive the driving shaft 23 2 synchronously rotates, the driving shaft 232 drives the driving sprocket 231 thereon to rotate synchronously, and through the connection transmission between the driving sprocket 231 and the chain, the other driving sprocket 231 drives the rotating shaft 201 to rotate synchronously. The rotating shaft 201 continues to drive the rotating shaft 201 and the filter plate 202 to rotate in the above situation, and the pool water is continuously filtered. The two methods of driving the rotating shaft 201 to rotate by the above pool water flow and cooperating with the external motor drive are used to realize continuous filtering of the pool water, which makes full use of the flow potential energy of the water, reduces energy loss, and reduces the cost of filtration.

[0048] S2. During the process of the filter plate 202 being driven to rotate by the rotating shaft 201, the filter screen 204 and the cleaning plate 1 211 rotate relative to each other. The cleaning plate 1 211 is always in close contact with the outer arc surface of the filter screen 204 under the elastic force generated by the deformation of the spring rod 212. The cleaning plate 1 211 cleans the outer arc surface of the filter screen 204. Secondly, the filter plate 202, the fixing bar 213 and the cleaning plate 2 214 also rotate relative to each other. The cleaning plate 2 214 is in close contact with the inner arc surface of the filter screen 204. Therefore, during the whole rotation of the filter screen 204, the cleaning plate 2 214 contacts the filter screen 204. The inner arc surface of 4 is cleaned and scraped. By cleaning the inner and outer arc surfaces of the filter screen 204, the problem of clogging of the filter screen 204 is avoided, and the filtering effect of the filter screen 204 on the pool water is guaranteed. When the filtering operation is completed, the storage box 31 is separated from the filtering pipe 1, and the filter plate 202 and the filter screen 204 are controlled to rotate by an external motor, so that the cleaning plate 1 211 is located between adjacent filter screens 204, and the cleaning plate 1 211 is avoided. Obstacles to the removal of the filter screen 204 are avoided. Then the filter screen 204 is taken out and the filter screen 204 is cleaned or replaced, so as to ensure the filtering effect of the filter screen 204 on the pool water.

[0049] S3. In the initial state, the control column 323 is located in the circumferential groove 321 on the front side of the corresponding rotating roller 320. Due to the limitation of the depth of the circumferential groove 321, the rotating roller 320 and the rotating shaft 201 can only rotate a full circle, and the annular baffle 206 blocks the corresponding fan-shaped groove 30.

[0050] After a period of filtration, the water level drops below the mounting circular plate 324. At this time, the impurities accumulated in the filter pipe 1 can be cleaned. Specifically, the mounting circular plate 324 is manually pulled to move the control column 323 upward to disengage it from the circumferential groove 321 on the front side. The impact force of the pool water flow on the filter plate 202 causes the rotating shaft 201 to drive the rotating roller 320 to move forward, and then quickly loosens the mounting circular plate 324. The lower end of the control column 323 contacts the rotating roller 320. As the rotating shaft 201 drives the rotating roller 320 to continue to rotate, the control column 323 always contacts the annular surface of the rotating roller 320 under the elastic force of the second spring 325. When the circumferential groove 321 on the rear side is aligned with the control column 323, under the action of the rebound force of the second spring 325, the control column 323 moves down to the circumferential groove 321 on the rear side. The circumferential groove 321 on the rear side cooperates with the control column 323 so that the rotating roller 320 can only rotate in the circumferential direction.

[0051] In the process of the rotating roller 320 driving the rotating shaft 201 to move forward, the rotating shaft 201 drives the filter plate 202 and the annular baffle 206 to move forward synchronously, and the annular baffle 206 is staggered from the storage box 31. At this time, the inner cavity of the storage box 31 is connected with the inner cavity of the filter pipe 1. During the flow of pool water, the impurities accumulated on the outer arc surface of the filter plate 202 are impacted into the storage box 31 for collection, and the filtering operation of the pool water is continuously performed in the process.

[0052] At the same time, in the process of the above-mentioned rotating roller 320 moving forward, the spring three 326 is compressed and deformed, and the elastic force generated by the deformation of the spring three 326 acts on the rotating roller 320. However, at this time, the elastic force generated by the compression of the spring three 326 is smaller than the impact force of the pool water on the filter plate 202. When there are too many impurities in the storage box 31 that need to be processed, the installation circular plate 324 is manually pulled upward, and the control column 323 moves up and out of the circumferential groove 321 on the rear side. At the same time, the sealing door is controlled to move down a certain distance, reducing the flow speed and flow rate of the pool water, so that the force of the pool water impacting the rotating shaft 201 is smaller than the elastic force generated by the compression of the spring three 326. At this time, the elastic force generated by the deformation of the spring three 326 causes the rotating shaft 201 to drive the rotating roller 320 to move backward, and then the installation is released. The circular plate 324, as the rotating shaft 201 drives the rotating roller 320 to rotate continuously, the control column 323 always contacts the annular surface of the rotating roller 320 under the elastic force of the second spring 325. After the circumferential groove 321 on the front side is aligned with the control column 323, under the elastic force of the second spring 325, the control column 323 moves down to the circumferential groove 321 on the front side. The circumferential groove 321 on the front side cooperates with the control column 323 so that the rotating roller 320 can only rotate in the circumferential direction. Therefore, the annular baffle 206 blocks the fan-shaped groove 30 again, and then the threaded cap 332 is manually rotated to remove the corresponding two storage boxes 31 and clean the impurities in the storage boxes 31. After cleaning, the storage boxes 31 are installed on the filter pipe 1 again, and the sealing door is moved up to continue filtering. While the filtering operation is ongoing, the impurities filtered out in the filter pipe 1 can be cleaned, and the storage box 31 is guaranteed to have a capacity for collecting impurities without affecting the filtering efficiency, thereby avoiding the problem of the filter pipe 1 being blocked due to excessive impurities in the filter pipe 1 not being cleaned in time.

[0053] In the process of the pool water flushing impurities into the storage box 31, the obstruction plate 34 and the obstruction block 340 provided in the storage box 31 allow the impurities flushed into the storage box 31 to continue to stay in the storage box 31. At the same time, the obstruction plate 34 and the obstruction block 340 absorb the impact force of the pool water, thereby avoiding the problem of impurities in the storage box 31 being flushed out due to subsequent impact of the pool water, and facilitating the storage box 31 to collect the filtered impurities. Secondly, the through groove 1 341 on the obstruction plate 34 and the through groove 2 342 on the obstruction block 340 ensure that the pool water flows in the storage box 31 while reducing the impact of the pool water in the storage box 31, thereby avoiding the problem of impurities in the storage box 31 being brought out by the flow of pool water, and improving the collection efficiency of the storage box 31.

[0054] When the storage box 31 is taken out, a person manually reaches into the storage box 31 from the opening of the storage box 31 to press the two locking strips 351 on the same blocking plate 34. The horizontal section of the locking strip 351 is made of elastic material, so the two locking strips 351 are close to each other, releasing the cooperation between the triangular section of the locking strip 351 and the inner wall of the accommodating groove 350. Then, the blocking plate 34 and the blocking block 340 are taken out, and cleaning them facilitates the cleaning of the storage box 31 at the same time, thereby improving the utilization rate.
