Description

Technical Field

[0001] The present invention relates to the technical field of pool cleaning and drainage, and particularly relates to a system for cleaning floating objects on the pool surface and silt at the bottom of a pool. Background Art

[0002] Public pools such as hot spring pools or swimming pools are usually set outdoors for people to use. Such pools are basically open-air without canopies for shielding. Therefore, silt such as fallen leaves of trees, vegetation, flowers, plants, sand, etc. will enter the pool, seriously affecting people's normal use. Currently, most floating objects such as fallen leaves of trees and vegetation on the pool surface are cleaned by manual fishing. For the silt at the bottom of the pool, usually after emptying the pool, the silt is washed manually and discharged through the drainage outlet at the bottom of the pool. However, such a cleaning method is not only time-consuming and laborious, but also affects normal business. At the same time, the drainage valve set at the bottom of the pool can only be fully opened or fully closed, and cannot control the water flow rate of the drainage outlet. Furthermore, it cannot ensure the stability of the pool water surface. Moreover, this drainage valve is set in the hot spring pool or underground valve well, and it is very inconvenient to open or close. Summary of the Invention

At the same time, the drainage valve set at the bottom of the pool can only be fully opened or fully closed, and cannot control the water flow rate of the drainage outlet. Furthermore, it cannot ensure the stability of the pool water surface. Moreover, this drainage valve is set in the hot spring pool or underground valve well, and it is very inconvenient to open or close, the present invention provides a system for cleaning floating objects on the pool surface and silt at the bottom of a pool.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A system for clearing floating objects on the pool surface and silt at the bottom of a pool, comprising an overflow drainage channel, a slag filtering and debris blocking net, a circulating garbage bin, and a flute-hole type overflow partitioner. The overflow drainage channel is arranged at the overflow opening of the pool. The slag filtering and debris blocking net is rotatably connected to one side of the upper part of the overflow drainage channel far from the overflow opening of the pool through a rotary hinge. The circulating garbage bin is arranged behind and below the slag filtering and debris blocking net. The flute-hole type overflow partitioner includes a limit adjuster, a socket isolation valve, a flute-hole type socket rod, and an anti-sway hole plate. The limit adjuster includes a hollow mounting seat. A rotary handle is fixedly connected to the side of the hollow mounting seat. A rotation angle scale is arranged on the channel base of the overflow drainage channel below the rotary handle. An installation hole is opened at the bottom of the hollow mounting seat. The socket isolation valve includes an isolation sleeve and a valve core. The isolation sleeve is fixed in the channel of the overflow drainage channel and is connected to the bottom comprehensive drainage pipe. A water inlet for connecting to the bottom drainage pipe of the pool is arranged on the side wall of the isolation sleeve. The valve core is tightly and rotatably sleeved in the hollow interior of the isolation sleeve. The valve core includes an integrally formed upper cylinder and a lower cone. A notch step that can be rotated to be opposite to the water inlet is formed along the axial direction on the side wall of the upper cylinder. The starting position of the notch of the notch step corresponds to the position of the rotary handle. A sludge discharge hole communicating with the hollow interior of the valve core is opened at the bottom of the upper cylinder inside the notch step. The upper end of the flute-hole type socket rod passes through the installation hole and is fixedly connected to the hollow mounting seat. The lower end of the flute-hole type socket rod is fixedly inserted into the hollow interior of the valve core. The hollow interior of the flute-hole type socket rod communicates with the sludge discharge hole at the bottom of the upper cylinder. A plurality of overflow hole groups are axially spaced on the flute-hole type socket rod above the connection with the valve core. Each overflow hole group includes a plurality of overflow holes opened on the same circumferential surface of the flute-hole type socket rod. The plurality of overflow holes communicate with the internal hollow of the flute-hole type socket rod. The anti-sway hole plate is fixedly sleeved on the middle and upper part of the flute-hole type socket rod. The anti-sway hole plate is provided with water passing holes and the outer peripheral surface is fixed in the channel of the overflow drainage channel.

[0006] Compared with the prior art, for the floating objects on the pool surface and the sludge at the bottom of the pool provided by the present invention, when the water temperature of the pool is kept constant by replenishing water in the pool, the overflow water and the floating objects on the pool surface of the pool enter the overflow drainage channel through the overflow outlet of the pool. The slag filtering and dirt intercepting net arranged on the upper part of the overflow drainage channel separates the overflow water and the floating objects on the pool surface of the pool. Thus, the treatment of the floating objects on the pool surface and the overflow water of the pool is realized in the same link, and the floating objects on the pool surface are automatically collected by the overflow water of the pool. Then, the overflow water of the pool flows into the overflow drainage channel, and the floating objects on the pool surface remain on the slag filtering and dirt intercepting net. Subsequently, the floating objects on the pool surface can be poured into the circulating dustbin at the lower rear by manually rotating the slag filtering and dirt intercepting net. Thus, the difficulty of collecting and dumping the floating objects on the pool surface is reduced, the quick cleaning of the floating objects on the pool surface is realized, the labor intensity in the collection link of the floating objects on the pool surface is reduced, and time and labor are saved; when cleaning the sludge at the bottom of the pool, a person first holds the rotating handle and rotates it. The rotating handle drives the flute hole type socket rod fixedly connected with the hollow mounting seat to rotate, and then drives the valve core fixedly connected with the flute hole type socket rod to rotate in the hollow interior of the isolation sleeve. By observing the rotation angle corresponding to the rotation angle scale on the pool overflow drainage channel trench base relative to the rotating handle, the opening degree corresponding to the notch step on the socket isolation valve can be determined, so as to adjust the opening degree of the drainage outlet at the bottom of the pool to realize the controllable adjustment of the water discharge flow rate at the drainage outlet at the bottom of the pool. Furthermore, the stability of the water surface of the pool can be guaranteed and the overflow water at the top of the pool and the drainage at the bottom of the pool can be realized; at the same time, on the basis of realizing the controllable adjustment of the water discharge flow rate at the drainage outlet at the bottom of the pool, by controlling the size of the drainage outlet at the bottom of the pool to adjust the drainage flow rate and drainage speed, the continuous replenishment and drainage of the pool water and the cleaning of the sludge at the bottom of the pool without emptying can be realized, that is, the sediment entering the pool can be taken away by the drainage water flow at the bottom of the pool, the continuous drainage and sludge cleaning at the bottom of the pool are realized, and the sediment at the bottom of the pool is basically no longer accumulated, only some large stones cannot be washed away, which prolongs the pool cleaning time. The discharged sediment is discharged through the sludge discharge hole at the bottom of the upper cylinder and the overflow hole on the flute hole type socket rod, and no sediment accumulates and remains at the socket isolation valve after being washed by the water flow; in addition, the cleaning and drainage water flowing out from the drainage outlet at the bottom of the pool flows into the pool overflow drainage channel through the socket isolation valve, and the overflow water overflowing from the overflow outlet at the top of the pool also flows into the pool overflow drainage channel after passing through the slag filtering and dirt intercepting net. Then, the water in the overflow drainage channel is directly discharged into the bottom comprehensive drainage pipe through the upper end hollow flow port of the flute hole type socket rod and the overflow hole on the flute hole type socket rod; the anti-vibration orifice plate fixedly sleeved in the middle and upper part of the flute hole type socket rod can enhance the stability of the flute hole type socket rod and prevent it from shaking, so that the deviation can be controlled within two degrees when the flute hole type socket rod rotates.So far, innovatively, on the one hand, a slag filtering and trash intercepting net and a circulating trash bin are arranged above the overflow drainage channel in this application, realizing the automatic collection of floating objects on the pool surface through the overflow water of the pool, which is fast and labor-saving; on the other hand, by manually operating the flute-hole type overflow partition device on the ground of the pool top, it is very convenient to open or close the socket isolation valve at the bottom. By controlling the socket isolation valve to close the bottom drain and increasing the flow rate of the water replenishment port of the pool, the drainage flow rate and velocity of the overflow port of the pool can be increased, thereby accelerating the cleaning of floating objects on the pool surface. At the same time, by controlling the opening degree of the socket isolation valve to adjust and control the water discharge flow rate of the bottom drain of the pool, continuous drainage and silt cleaning at the bottom of the pool can be achieved, and the liquid level height of the pool can be adjusted and the water surface of the pool can be kept stable, saving time and effort while keeping the pool in normal operation, which has very important practical significance.

A rotation angle scale (not shown in the figure) is provided on the trench base 11 of the overflow drainage channel 1 below the rotary handle 412. An installation hole is opened at the bottom of the hollow mounting seat 411. The socket isolation valve 42 includes an isolation sleeve 421 and a valve core 422. The isolation sleeve 421 is fixed in the channel 12 of the overflow drainage channel 1 and is connected to the bottom comprehensive drainage pipe 45, playing a role in sealing and preventing water leakage and protecting the valve core 422. A water inlet 4211 for connecting to the pool bottom drainage pipe 46 is provided on the side wall of the isolation sleeve 421. The valve core 422 is closely and rotatably sleeved in the hollow interior of the isolation sleeve 421. The valve core 422 includes an integrally formed upper cylinder 4221 and a lower cone 4222. A notch step 42211 that can be rotated to be opposite to the water inlet 4211 is formed along the axial direction on the side wall of the upper cylinder 4221. The starting position of the notch of the notch step 42211 corresponds to the position of the rotary handle 412. Thus, it is convenient to determine the opening degree of the bottom valve core 422 through the rotation angle of the rotary handle 412, and to control the opening degree of the socket isolation valve 42 in real time, and further adjust the opening degree of the pool bottom drainage port to realize the regulation of the water discharge flow rate of the pool bottom drainage port. At the same time, by pressing down the rotary handle 412 with force, the valve core 422 and the isolation sleeve 421 can be pressed tightly to ensure the tight sealing of the bottom socket isolation valve 42.

The anti-vibration hole plate 44 is fixedly sleeved on the middle and upper part of the flute-hole type socket rod 43 to achieve support and prevent the flute-hole type socket rod 43 from shaking during rotation. The anti-vibration hole plate 44 is provided with water passing holes 441 and its outer peripheral surface is fixed in the channel 12 of the overflow drainage channel 1.;

[0024] Compared with the prior art, for the floating debris on the pool surface and the silt cleaning and discharging system at the bottom of the pool provided by the present invention, when the water temperature of the pool is kept constant by replenishing water in the pool, the overflow water and the floating debris on the pool surface of the pool enter the overflow drainage channel through the overflow outlet of the pool. The slag filtering and debris blocking net arranged on the upper part of the overflow drainage channel separates the overflow water and the floating debris on the pool surface of the pool, thereby realizing the treatment of the floating debris on the pool surface and the overflow water of the pool in the same link, and automatically collecting the floating debris on the pool surface through the overflow water of the pool. Then the overflow water of the pool flows into the overflow drainage channel, and the floating debris on the pool surface remains on the slag filtering and debris blocking net. Subsequently, the floating debris on the pool surface can be poured into the recycling dustbin at the rear lower part by manually rotating the slag filtering and debris blocking net, thereby reducing the difficulty of collecting and dumping the floating debris on the pool surface, realizing the quick cleaning of the floating debris on the pool surface, reducing the labor intensity in the collection link of the floating debris on the pool surface, saving time and effort; when realizing the cleaning of the silt at the bottom of the pool, a person first holds the rotating handle and rotates it. The rotating handle drives the flute-hole type socket rod fixedly connected with the hollow mounting seat to rotate, and then drives the valve core fixedly connected with the flute-hole type socket rod to rotate inside the hollow part of the isolation sleeve. By observing the rotation angle corresponding to the rotation angle scale of the rotating handle relative to the ditch base of the pool overflow drainage channel, the opening degree corresponding to the notch step on the socket isolation valve can be determined, so as to adjust the opening degree of the drainage outlet at the bottom of the pool to realize the controllable adjustment of the water discharge flow rate at the drainage outlet at the bottom of the pool, and further ensure the stability of the water surface of the pool and realize the overflow water discharge from the pool top and the drainage at the bottom of the pool; at the same time, on the basis of realizing the controllable adjustment of the water discharge flow rate at the drainage outlet at the bottom of the pool, by controlling the size of the drainage outlet at the bottom of the pool to adjust the drainage flow rate and drainage speed, continuous water replenishment and drainage and silt cleaning of the pool water and cleaning the silt at the bottom of the pool without emptying can be realized, that is, the sediment entering the pool can be taken away by the drainage water flow at the bottom of the pool, realizing continuous drainage and silt cleaning at the bottom of the pool, and basically no sediment accumulates at the bottom of the pool, only some large stones cannot be washed away, prolonging the pool cleaning time, and the discharged sediment is discharged through the sludge discharge holes at the bottom of the upper cylinder and the overflow holes on the flute-hole type socket rod, and no sediment accumulates and remains at the socket isolation valve after being washed by the water flow; in addition, the silt cleaning and drainage flowing out from the drainage outlet at the bottom of the pool flows into the pool overflow drainage channel through the socket isolation valve, and the overflow water overflowing from the overflow outlet at the top of the pool also flows into the pool overflow drainage channel after passing through the slag filtering and debris blocking net. Then the water in the overflow drainage channel is directly discharged into the bottom comprehensive drainage pipe through the upper hollow flow port of the flute-hole type socket rod and the overflow holes on the flute-hole type socket rod; the anti-vibration orifice plate fixedly sleeved in the middle and upper part of the flute-hole type socket rod can enhance the stability of the flute-hole type socket rod to prevent shaking, so that the deviation can be controlled within two degrees when the flute-hole type socket rod rotates.So far, innovatively, on the one hand, a slag and debris interception net and a recycling dustbin are arranged above the overflow drainage channel in this application, realizing the automatic collection of floating objects on the pool surface through the overflow water of the pool, which is fast and labor-saving; on the other hand, by manually operating the flute-type overflow partition device on the ground of the pool top, it is very convenient to open or close the socket isolation valve at the bottom. By controlling the socket isolation valve to close the bottom drain and increasing the flow rate of the water replenishment port of the pool, the drainage flow rate and velocity of the overflow port of the pool can be increased, thereby accelerating the cleaning of floating objects on the pool surface. At the same time, by controlling the opening degree of the socket isolation valve to adjust and control the water discharge flow rate of the bottom drain of the pool, continuous drainage and silt cleaning at the bottom of the pool can be achieved, and the liquid level height of the pool can be adjusted and the water surface of the pool can be kept stable. It saves time and effort and can also keep the pool in normal operation, which has very important practical significance.

Thus, by driving the worm in the screw lift 413 to rotate by a motor or manually, the screw rod 415 in the screw lift 413 can be driven to move up and down. Then, through the hollow mounting seat 411, the flute-type socket rod 43 and the valve core 422 can be lifted or lowered, which is convenient for the removal, fixation and maintenance of the overflow partition device.

Of course, those skilled in the art can also adopt other structural methods to achieve this on the basis of this embodiment.

[0031] As a specific embodiment, both the isolation sleeve 421 and the valve core 422 are made of wear-resistant elastic materials, with a temperature resistance of 0-50 °C. Preferably, the wear-resistant elastic material is an existing silicone rubber or elastic plastic. Thus, it is not only cheap in price, but also can prevent corrosion and scale formation. After use, there is no phenomenon of scale blocking the valve and corrosion of the equipment, and it can ensure smooth drainage for a long time and stably. And through regular disinfection, no bacteria are generated. At the same time, it can also reduce the setting of more than 70% of the valve wells and save more than 50% of the valve investment funds.

[0032] As a specific embodiment, please refer to Figure 3 As shown in the figure, both the notch angle θ of the notch step 42211 and the scale range of the rotation angle scale are 0-120 degrees. This design can better adjust the water discharge flow rate of the water discharge port at the bottom of the pool and ensure the stability of the water surface of the pool. When the water discharge port is fully opened, it is the maximum water discharge flow rate.

[0033] As a specific embodiment, the slope of the sludge discharge hole 42212 formed at the bottom of the upper cylinder 4221 is 1% - 3%, and such slope design is very convenient for clearing the sediment at the bottom of the pool.
