Technical Field
[0001] The utility model belongs to the technical field related to swimming pools, and specifically relates to a pipe layout structure for the bottom of a swimming pool without requiring sewage suction. Background Art
[0002] Swimming pools are specialized venues for swimming, where people can exercise or compete. Most swimming pools are built above ground and can be categorized as either regular or heated pools, depending on the water temperature. They are available in both indoor and outdoor locations. Official competition pools are 50 meters long, at least 21 meters wide, and at least 1.8 meters deep. Pools used for swimming, diving, and water polo are 1.3 to 3.5 meters deep. Pools with a 10-meter diving platform should be 5 meters deep. The water temperature in swimming pools should be maintained at 27 to 28°C. Filtration and disinfection equipment should be in place to keep the water clean. In existing swimming pools, water is usually supplied into the swimming pool through a water inlet below the water surface on the end wall or side wall of the swimming pool. The water is then sucked into the swimming pool by a circulating water pump through a return water inlet located at the bottom of the swimming pool, and sent to a filter to remove impurities in the return water and reduce the turbidity of the return water. The return water inlet at the bottom of the swimming pool is set at one end or in the middle of the swimming pool bottom, and is usually provided with two or four. The water in the swimming pool is discharged through the return water inlet, filtered and purified, and then circulated back into the swimming pool. Due to the small number of return water inlets and the influence of the arrangement of the pipes, short-circuit and uneven return water will occur, resulting in local dead water areas in the water distribution and return water, which has a great impact on the water circulation and water quality control of the swimming pool. At the same time, since the dirt in the swimming pool must be completely discharged through the return water inlet, a single return water inlet needs to discharge a lot of dirt, which can easily cause the return water inlet to be blocked. The cleaning and unblocking work brings great inconvenience to the maintenance of the swimming pool.
[0003] In view of this, the present utility model is proposed. Utility Model Content

The pool wall lamp 4 is used to illuminate the swimming pool, which can not only provide night light supplement, but also enhance the atmosphere. It is beautiful and practical.
[0030] The working principle of the present utility model is as follows: the bottom fabric of the swimming pool is provided with a water outlet nozzle 5, and three adjacent water outlet nozzles 5 are connected in a straight line or at right angles. Each three water outlet nozzles 5 are supplied with water separately through a pipe to ensure that the water outlet nozzles 5 discharge water evenly, thereby avoiding the problem of too many water outlet nozzles 5 being provided on one pipe, resulting in unstable water pressure and affecting the water discharge effect of the water outlet nozzles 5. The water supply branch pipe 17 is connected to the water inlet control valve 16, and each water inlet control valve 16 controls the water supply of the six water supply branch pipes 17;
[0031] When the swimming pool is cleaned, the valve on the sewage suction pipe 9 where the sewage suction port 6 is located is opened, and the water in the swimming pool enters the sewage suction pipe 9 through the sewage suction port 6. The sewage suction port 6 is located in the overlapping area covered by the water outlet nozzle 5. Each sewage suction port 6 discharges sewage evenly. The sewage suction port 6 is equipped with a return pipe filter anti-blocking head 18 for basic filtration of the water in the swimming pool, which can effectively avoid the blockage of the sewage suction pipe 9. At the same time, the return pipe filter anti-blocking head 18 is a detachable structure, and an upper filter screen plate 21 and a lower filter screen plate 19 are provided inside. In order to effectively block large debris and prevent it from entering the sewage suction pipe 9, the water in the sewage suction pipe 9 enters the circulation treatment box 11 through the circulation main pipe 10. The circulation treatment box 11 is equipped with a filtering device, a heating device, a water quality balance device and a disinfection device (this is the unit device of the existing circulation treatment box and will not be described in detail here). After the water in the swimming pool is treated, it is discharged from the circulation water supply pipe 12 and supplied to the water supply branch pipe 17 and the pool bottom nozzle water inlet pipe 15, and is sprayed out through the water outlet nozzle 5, realizing the circulation treatment of the swimming pool water;
[0032] This pipe layout can effectively remove dirt and impurities accumulated on the surface of the pool water, ensuring that purified water is delivered to every part of the swimming pool. The evenly arranged water outlet nozzles 5 on the bottom of the pool can ensure uniform water flow in the pool, preventing phenomena such as vortexes, short currents and dead water areas. It can evenly and effectively exchange the purified clean water in an orderly manner, renew the water in the pool that has not yet been purified again, improve the pool water purification effect, and ensure that the water quality (cleanliness, disinfection residue, pH value and water temperature, etc.) in different water layers and different parts of the pool is uniform;
[0033] The arrangement of the rapid water return port 7 and the rapid water return pipe 13 can achieve rapid water return processing, facilitating deep cleaning of the swimming pool;
[0034] The novel structure of the present invention is rationally designed and easy to install and use. A sewage suction port 6 is provided on the bottom of the pool. The sewage suction port 6 is provided at the center of a square formed by four adjacent water outlet nozzles 5, which is the overlapping coverage area of the water outlet nozzles 5. When draining backwater, the drainage efficiency can be accelerated to avoid local stagnant water and uneven drainage. The sewage suction pipe 9 connects the sewage suction ports 6 in a row in the width direction of the pool bottom in series, and aggregates them to the circulation main pipe 10 to supply them to the circulation treatment box 11 for centralized treatment. A return pipe filter anti-blocking head 18 is provided at the sewage suction port 6. Multiple sewage suction ports 6 are provided to divert the sewage, and the return pipe filter anti-blocking head 18 is used for basic filtration, which can effectively reduce the risk of blockage of the sewage suction pipe 9.
