[0002] A swimming pool skimmer is a swimming pool cleaning device used to remove debris on the pool surface, such as leaves, garbage, small insects, etc. There are various types of swimming pool skimmers, including wall-mounted, wide-mouth skimmers, etc. They keep the swimming pool clean and the water quality by sucking up the debris on the pool surface. These devices are crucial for maintaining the hygiene and beauty of the swimming pool and are an essential part of swimming pool management. The swimming pool water purification process is as follows: 1. Prefiltration: Preliminary filtration is carried out through the swimming pool skimmer to remove large debris, such as leaves or larger particles; 2. Main filtration: Through quartz sand filters and diatomaceous earth filters, etc., smaller particles and suspended substances are removed to provide higher-precision filtration; 3. Water quality balance: By adding chemical agents, such as pH regulators, alkaline regulators, etc., to adjust water quality parameters; 4. Disinfection: Adding chlorine products for disinfection to kill bacteria and viruses, and using ozone as a disinfectant. It is a strong oxidant that can effectively disinfect and reduce the dosage of chlorine at the same time; 5. Recycling back to the swimming pool: The treated water returns to the swimming pool through the pipeline to continue the next cycle.

[0003] Currently, the water inlet section of the swimming pool skimmer is designed in a straight-in type, with a slow flow rate of the flowing water, low conversion efficiency of water flow kinetic energy, and inability to actively and effectively suck in debris. This results in a large amount of debris remaining in the pool, increasing the working load of the filter and reducing the filtration efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a swimming pool skimmer that can filter debris more efficiently and energy-savingly and improve its filtration effect.

[0005] The described swimming pool skimmer includes a vertically arranged front panel frame and a horizontally arranged rectangular water inlet pipe. A rear panel frame connected to the front panel frame is arranged on the right side of the water inlet pipe. A skimming shell is arranged at the left end of the water inlet pipe. An installation groove communicating up and down is opened on the front side wall at the left end of the skimming shell. A connecting pipe connected and communicating with the skimming shell is arranged at the installation groove. A water outlet cylinder is fixed at the lower end of the connecting pipe. Two water outlet pipes connected and communicating with the water outlet cylinder are arranged at the bottom of the water outlet cylinder. A filter basket is arranged in the water outlet cylinder. The size of the water inlet pipe gradually shrinks from the right end to the left end in a funnel shape, and the bottom of the water inlet pipe is inclined with the left end lower and the right end higher. A rotating rod is rotatably connected in the skimming shell. A baffle inclined with the left end higher and the right end lower is arranged on the rotating rod. A floating plate is horizontally arranged on the left side of the baffle. A pushing member for lifting the floating plate is arranged at the bottom of the floating plate.

[0006] Further, the pushing member is an airbag.

[0007] Further, a cover plate is arranged above the connecting pipe. A through groove that is vertically communicated and has a circular structure is formed in the cover plate. A floor drain is arranged in the through groove. The floor drain includes a fixed pipe inserted into the connecting pipe, and a pipe cover is arranged at the top of the fixed pipe.

[0008] Further, the diameter of the through groove is smaller than the diameter of the pipe cover.

[0009] Further, two leakage holes for taking the pipe cover are formed in the pipe cover.

[0010] Further, a handle for conveniently taking the filter basket is arranged at the opening of the filter basket.

[0011] Further, the left side wall of the scum skimming housing has an arc structure.

[0012] Further, a plurality of first reinforcing ribs are arranged on the outer side wall of the scum skimming housing.

[0013] Further, a plurality of second reinforcing ribs are arranged on the outer side wall of the water outlet cylinder and are distributed in a circumferential array along the center of the water outlet cylinder.

[0026] Embodiment 1

[0027] A pool skimmer described in this embodiment, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown in the figure, it includes a vertically arranged front panel frame 1 and a horizontally arranged rectangular water inlet pipe 4. A rear panel frame 2 connected to the front panel frame 1 is arranged on the right side of the water inlet pipe 4. A skimming shell 9 is arranged at the left end of the water inlet pipe 4. An installation groove communicating up and down is opened on the front side wall at the left end of the skimming shell 9. A connecting pipe 12 connected and communicating with the skimming shell 9 is arranged at the installation groove. A water outlet cylinder 15 is fixed at the lower end of the connecting pipe 12. Two water outlet pipes 17 connected and communicating with the water outlet cylinder 15 are arranged at the bottom of the water outlet cylinder 15. A filter basket 16 is arranged in the water outlet cylinder 15. Both the front panel frame 1 and the rear panel frame 2 are rectangular. The left side wall of the rear panel frame 2 is welded or pasted with the water inlet pipe 4. The water inlet pipe 4 is of a rectangular structure. The left side wall of the water inlet pipe 4 is welded or pasted with the skimming shell 9. The water inlet pipe 4 is connected and communicating with the skimming shell 9. An installation groove is opened at the left end of the front side wall of the skimming shell 9. The connecting pipe 12 is welded or pasted at the installation groove. A connecting groove connected and communicating with the skimming shell 9 is opened on the connecting pipe 12. The water outlet cylinder 15 is welded or pasted at the lower end of the connecting pipe 12. Two fixing holes are opened at the bottom of the water outlet cylinder 15. The water outlet pipes 17 are arranged in the fixing holes respectively. One end of the water outlet pipe 17 is welded or pasted in the fixing hole, and the other end of the water outlet pipe 17 is located below the water outlet cylinder 15 and is connected to the pumping system. The filter basket 16 is placed in the water outlet cylinder 15 to collect and filter the sundries flowing into the water outlet cylinder 15. During installation, the water outlet cylinder 15, the connecting pipe 12, the skimming shell 9, the water inlet pipe 4 and the rear panel frame 2 are buried on the side of the swimming pool and covered by the swimming pool building. The top height of the skimming shell 9 is lower than the top height of the connecting pipe 12. The rear panel frame 2 is located on the side wall of the swimming pool. A swimming pool waterproof membrane is arranged between the front panel frame 1 and the rear panel frame 2 to ensure the sealing between the side of the rear panel frame 2 and the swimming pool wall and prevent the water in the swimming pool from leaking. The swimming pool water enters the water inlet pipe 4 through the front panel frame 1 and the rear panel frame 2. The front panel frame 1 and the rear panel frame 2 are connected by threads. A number of uniformly distributed threaded pipes are arranged on the left side wall of the rear panel frame 2. A number of threaded holes connected and communicating with the threaded pipes are opened on both the rear panel frame 2 and the front panel frame 1 corresponding to the threaded pipes. The threaded holes on the rear panel frame 2 and the front panel frame 1 correspond to each other. During installation, nuts are sequentially screwed into the threaded holes on the front panel frame 1 and the rear panel frame 2, and then into the threaded pipes on the left side wall. The nuts are in threaded fit with the threaded pipes, so as to connect the front panel frame 1 and the rear panel frame 2, which is convenient for the installation and disassembly of the front panel frame 1 and also makes the connection between the two closer and the sealing better.The water in the swimming pool enters the water inlet pipe 4 through the front panel frame 1 and the rear panel frame 2, passes through the skimming shell 9 and enters the connecting pipe 12 from the connecting groove, and finally flows into the water outlet cylinder 15 from the connecting pipe 12. The filter basket 16 in the water outlet cylinder 15 intercepts sundries such as leaves, garbage, and small insects in the water, and preliminarily filters the larger sundries in the water through the filter basket 16. The water flow flows into the filter through the water outlet pipe 17 for higher-precision filtration. The filter basket 16 can be taken out of the water outlet cylinder 15 through the connecting pipe 12, and the sundries intercepted in the filter basket 16 are cleaned. The water outlet pipe 17 is connected to the filter through a pumping system. The pumping system is a water pump or a water pump. The water in the swimming pool is sucked into the connecting pipe 12 through the water inlet pipe 4 and the skimming shell 9 by the water pump or the water pump, and is discharged into the filter from the water outlet end of the water pump or the water pump after passing through the water outlet cylinder 15 and the water outlet pipe 17. The filter is a quartz sand filter and a diatomaceous earth filter for fine filtration and purification of impurities in the swimming pool in the prior art. The quartz sand filter uses quartz sand as the filtering medium. Under a certain pressure, water with a higher turbidity is filtered through a certain thickness of granular or non-granular quartz sand, which can effectively intercept and remove suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odor, and some heavy metal ions in the water, so as to achieve the effect of reducing water turbidity and purifying water quality. The liquid filtered by the quartz sand filter is then filtered by the diatomaceous earth filter. The diatomaceous earth filter is a high-efficiency filtering device mainly using diatomaceous earth as the medium. It uses the fineness and porosity of diatomaceous earth particles to remove suspended particles, colloids, organic matter, heavy metals and other impurities in the water through a combination of physical and chemical methods, thereby improving water quality. The core part of the diatomaceous earth filter usually consists of a filter screen, a support screen and an outer frame. Its filter layer is formed by covering the filter element with a diatomaceous earth coating. The entire filtration cycle includes three steps: membrane laying, filtration and backwashing; through the double purification of the quartz sand filter and the diatomaceous earth filter, the swimming pool water reaches a better purification effect. The filtered and purified swimming pool water is disinfected and then discharged into the swimming pool again, so as to filter and purify the swimming pool water in a cycle;

[0028] The size of the right end to the left end of the water inlet pipe 4 gradually decreases and is funnel-shaped. The bottom of the water inlet pipe 4 is inclined with the left side lower and the right side higher. A rotating rod 3 is rotatably connected inside the skimming shell 9. A baffle 5 inclined with the left side higher and the right side lower is arranged on the rotating rod 3. A floating plate 7 is horizontally arranged on the left side of the baffle 5. A pushing member 8 for lifting the floating plate 7 is arranged at the bottom of the floating plate 7. The front and rear side walls of the water inlet pipe 4 gradually converge from right to left, so that the size of the left end of the water inlet pipe 4 is smaller than that of the right end, which is convenient for more sundries to enter the water inlet pipe 4 through the right end. The front and rear side walls of the water inlet pipe 4 are in a contracted shape. Based on Bernoulli's principle and the continuity equation, when water flows from a large cross-section to a small cross-section, due to the contraction of the cross-section, the pressure decreases at the small cross-section, the kinetic energy increases, and the flow velocity increases. Therefore, when the water flow encounters the gradual convergence of the front and rear side walls of the water inlet pipe 4, the water flow will gradually accelerate, which can actively increase the flow velocity of the water flow, greatly improve the suction rate of the swimming pool sundries and reduce the backflow, reduce the working load of the pumping system, and is more energy-saving and environmentally friendly;

[0029] The bottom of the water inlet pipe 4 is inclined with the left side lower and the right side higher. The angle between the top surface and the bottom surface of the water inlet pipe 4 is 15° - 35°. 15° ensures that the inclined surface is not too low to affect the efficiency of water flow inflow, and 35° ensures that it is not too high to increase the production cost and difficulty. Based on the principle of gravity and water flowing to lower places, the inclined surface facilitates the swimming pool water to more easily flow into the water inlet pipe 4. Even without the suction of the pumping machine for the swimming pool water, due to its fluidity, the water flow will flow into the skimming shell 9 from the right end of the water inlet pipe 4, guiding it, and thus achieving the effect of energy conservation. Only by the suction of the pumping system to increase the flow velocity of the water flow can its filtration efficiency be improved;

[0030] On the right side inside the skimming shell 9, a rotating rod 3 is provided. The rotating rod 3 is rotatably connected to the front and rear inner walls of the skimming shell 9 through a rotating shaft, and the rotating rod 3 is located above the inner bottom of the skimming shell 9. There is a certain gap between the rotating rod 3 and the inner bottom of the skimming shell 9 to facilitate the normal rotation of the rotating rod 3. However, only water flow or some fine particles can pass through this gap, and large impurities such as fallen leaves and animal corpses flow into the filter basket 16 through the gap between the floating plate 7 and the skimming shell 9; a baffle 5 is welded or adhered to the rotating rod 3. The baffle 5 is in an inclined shape with the left side higher than the right side. A horizontal floating plate 7 is welded or adhered to the left side of the baffle 5. During production, the baffle 5 and the floating plate 7 are of an integrally formed structure, which is convenient for production and makes its structure more firm. A pushing member 8 is provided at the bottom of the floating plate 7. The pushing member 8 can be a spring. The top of the spring is welded to the bottom of the floating plate 7, and the bottom of the spring is welded to the inner bottom of the pushing member 8. When water flow flows into the skimming shell 9 through the water inlet pipe 4, the water flow passes through the gap between the baffle 5, the floating plate 7 and the inside of the skimming shell 9. When the water flow passes through the floating plate 7, its gravity will compress the spring, causing the floating plate 7 to drive the baffle 5 to rotate around the rotating rod 3, and the gap between the floating plate 7 and the baffle 5 and the inside of the skimming shell 9 increases, enabling the water flow to pass better. When the pumping system stops sucking the water flow, the spring restores under its own spring force, thus lifting the floating plate 7. The floating plate 7 drives the baffle 5 to rotate around the rotating rod 3, and the gap between the floating plate 7 and the baffle 5 and the inside of the skimming shell 9 decreases. The floating plate 7 can block the sundries flowing into the filter basket 16 to prevent them from entering the swimming pool again;

[0031] Furthermore, the pushing member 8 is preferably an airbag. The top of the airbag is adhered to the bottom of the floating plate 7. The airbag in this embodiment is in an inflated state and floats on the water surface. The airbag can keep the floating plate 7 always above the water surface, and this process is autonomous without external support and will not increase the burden on the pumping system. The water level of the swimming pool is generally controlled within the middle range of the front panel frame 1. When the water flow is static, the airbag floats on the water surface and the floating plate 7 is above the water surface, providing resistance to the sundries, which can prevent the already collected sundries from floating back to the swimming pool again with the fluctuations of the water flow or the wind and re-polluting the water quality of the swimming pool. The airbag drives the floating plate 7 to automatically adjust its position according to the water level, which can well prevent the sundries from flowing back, enhance its filtering effect, does not require frequent cleaning and maintenance, reduces the labor cost, and makes it more reasonable, effective and energy-saving;

[0032] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown, a cover plate 10 is provided above the connecting pipe 12. A through groove that is circular in structure and communicates up and down is provided on the cover plate 10. A floor drain is provided in the through groove. The floor drain includes a fixed pipe inserted into the connecting pipe 12. A pipe cap 11 is provided at the top of the fixed pipe. A cover plate 10 is provided above the connecting pipe 12. A through groove in a circular structure is provided at the center of the cover plate 10. A floor drain is provided in the through groove. The floor drain includes a fixed pipe, and a pipe cap 11 is welded or adhered to the top of the fixed pipe. Two leak holes for taking the pipe cap 11 are provided at the center of the pipe cap 11. The diameter size of the leak holes is such that a child's finger cannot enter, and the maximum diameter does not exceed 8 MM, to prevent a child from taking out the pipe cap 11 out of curiosity and causing a safety hazard; the fixed pipe and the pipe cap 11 are of an integrally formed structure, which is convenient for production and use, and the diameter size of the through groove is smaller than the diameter size of the pipe cap 11 to prevent the pipe cap 11 from falling into the connecting pipe 12 and restricting the position of the pipe cap 11; the bottom of the pipe cap 11 is in contact with the top of the cover plate 10. During installation, the cover plate 10 is embedded in the ground, and the top of the cover plate 10 is at the same horizontal plane as the ground. The connecting pipe 12 is located underground. After the fixed pipe of the floor drain is inserted into the connecting pipe 12, the bottom of the pipe cap 11 of the floor drain contacts the top of the cover plate 10. The cover plate 10 and the floor drain seal the top end of the connecting pipe 12, preventing foreign objects from falling into the filter basket 16 through the top end of the connecting pipe 12, and it is also more beautiful and practical. The leak holes on the pipe cap 11 facilitate taking the floor drain out of the through groove, and also facilitate taking the filter basket 16 out or putting it into the connecting pipe 12 through the top end to clean the foreign objects in the filter basket 16. The leak holes also facilitate the dissipation of the odor emitted by the foreign objects in the filter basket 16;

[0033] As Figure 1 and Figure 6 shown, a handle 13 for conveniently taking the filter basket 16 is provided at the opening of the filter basket 16. The handle 13 is hinged to the inner wall of the opening of the filter basket 16. The handle 13 facilitates taking the filter basket 16, facilitating the cleaning of the collected foreign objects, and making it more convenient to use;

[0034] As Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the left side wall of the skimming shell 9 is of an arc structure. The front side of the left side wall of the skimming shell 9 is in contact with the outer side wall of the connecting pipe 12. The skimming shell 9 and the connecting pipe 12 as a whole are in an "L" - shaped structure. The arc - shaped left side wall of the skimming shell 9 facilitates the guidance of water flow. After the water flow passes through the skimming shell 9 and then enters the connecting pipe 12 through the connecting groove, the water flow forms a vortex in the connecting pipe 12 after passing through the arc - shaped side wall. Forming a vortex can filter foreign objects inside the filter basket 16, preventing the water flow from dispersing and the foreign objects from being washed away and scattered, filtering the foreign objects more efficiently and energy - savingly, thereby reducing the water flow resistance, making the water flow more smooth, reducing the operating noise, and reducing environmental noise pollution;

[0035] As Figure 1 、Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown in Figure 6 , several first reinforcing ribs 6 are provided on the outer wall of the skimming shell 9. The first reinforcing ribs 6 are welded or adhered to the outer wall of the skimming shell 9. The first reinforcing ribs 6 can effectively enhance the bearing capacity of the skimming shell 9, enhance its strength, improve its stability, and prevent it from deforming. Similarly, the first reinforcing ribs 6 are provided on the outer wall of the water inlet pipe 4; and several second reinforcing ribs 14 are provided on the outer wall of the water outlet cylinder 15 and are circumferentially arranged in an array along the center of the water outlet cylinder 15. The second reinforcing ribs 14 are welded or adhered to the outer wall of the water outlet cylinder 15 to enhance its strength and make it more durable;

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown in Figure 6 , the front panel frame 1 is made of PVC material. The PVC material is relatively light, which makes the front panel frame 1 more convenient in the installation, handling, and construction processes. The inner wall surface of the front panel frame 1 is smooth, and the resistance of the water flow passing through it is small, which helps to reduce the pressure loss inside it and improve the water flow velocity. The PVC material has high water pressure resistance strength, external pressure resistance strength, and impact resistance strength, and can better withstand the erosion of the water flow. Moreover, when the PVC material is used in combination with the pool waterproof membrane, a better sealing effect can be achieved to ensure the sealing between the front panel frame 1 and the pool wall.

[0037] During the actual use process, when the pumping system is started, the pool water enters the water inlet pipe 4 through the front panel frame 1 and the rear panel frame 2. The front and rear side walls of the water inlet pipe 4 are in a converging shape, which can actively increase the water flow velocity and reduce the water flow backflow. The inclined bottom of the water inlet pipe 4 can divert the water flow. After the water flow passes through the skimming shell 9, it flows into the connecting pipe 12 from the connecting groove and finally converges into the water outlet cylinder 15. The sundries carried in the water flow are preliminarily filtered through the filter basket 16. The preliminarily filtered water flow is further finely filtered and disinfected through the filter and then converges back into the pool to repeat the filtration of the pool water. When the pumping system stops working, the water flow stops flowing, and the pushing member 8 pushes the floating plate 7 above the water surface to block the sundries in the filter basket 16 from flowing back into the pool, further improving its filtration effect. Finally, the floor drain is opened to clean the sundries in the filter basket 16, which does not require frequent cleaning and maintenance, reduces the labor cost, and makes it more energy-saving and environmentally friendly.
