[0002] The water inlet of a swimming pool is typically connected to an inlet pipe, allowing water to flow into the pool through the pipe. This inevitably creates a gap between the inlet pipe and the edge of the inlet. In a water circulation system where water enters from the bottom and exits from the top, since the inlet is located at the bottom of the pool, water within the pool is prone to leaking through the gap between the inlet pipe and the edge of the inlet. Therefore, a waterstop is typically installed at the inlet of a swimming pool to prevent water leakage.
[0003] Existing water-stopping structures often use rubber seals or mechanical seals to achieve water-stopping effects. However, rubber seals are prone to aging and deformation, resulting in a decrease in sealing performance. Mechanical seals are complex, costly, and require high installation and maintenance requirements. Improper installation or even slight misalignment can not only affect the water-stopping effect, but can also cause water flow disturbances and noise, affecting the user experience of the pool.

[0040] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0041] like Figure 1 As shown, the swimming pool 1 includes a bottom wall and four side walls. The bottom wall is usually arranged roughly along the horizontal plane, and the side walls are arranged roughly along the vertical direction. The bottom wall is arranged at the bottom of the side walls, and the four side walls are sequentially arranged around the bottom wall and connected to each other to jointly define the swimming pool 1 with the opening facing upward.
[0042] The swimming pool 1 includes a water inlet 11, which is provided at the bottom of the swimming pool 1 and vertically penetrates the bottom wall of the swimming pool 1. It should be noted that the water inlet 11 has a certain thickness, which is the thickness of the bottom wall of the swimming pool 1.
[0043] A water inlet pipe 3 is provided at the water inlet 11 , and the water inlet pipe 3 passes through at least a portion of the bottom wall of the swimming pool 1 so that water can be injected into the swimming pool 1 through the water inlet pipe 3 .
[0044] There is a gap between the water inlet pipe 3 and the inner edge of the water inlet 11, and the water in the swimming pool 1 is likely to leak through the gap.
[0045] like Figure 2-Figure 4 As shown, in an exemplary embodiment of a water-stop device for a swimming pool water inlet of the present invention, the water-stop device for the swimming pool water inlet is used to stop water in the gap between the water inlet pipe 3 and the water inlet 11; the water-stop device for the swimming pool water inlet includes a flexible sleeve 2 and a rubber ring 4, at least the flexible sleeve 2 is arranged in the water inlet 11 along its length direction, the flexible sleeve 2 is sleeved on the outer periphery of the water inlet pipe 3, and a gap 21 is provided between the inner wall of the flexible sleeve 2 and the outer wall of the water inlet pipe 3; at least part of the flexible sleeve 2 is arranged at the water inlet 11 along its length direction, and the outer wall of the flexible sleeve 2 is in contact with the inner edge of the water inlet 11; the rubber ring 4 is arranged in the gap 21, and the rubber ring 4 is provided with a rubber ring through hole 41 for the water inlet pipe 3 to pass through; the rubber ring 4 is arranged in the gap 21 between the flexible sleeve 2 and the water inlet pipe 3, the inner wall of the rubber ring 4 abuts against the outer wall of the water inlet pipe 3, and the outer wall of the rubber ring 4 abuts against the inner wall of the flexible sleeve 2.
[0046] It should be noted that the flexible sleeve 2 is made of rubber or silicone. When the rubber ring 4 is arranged between the flexible sleeve 2 and the water inlet pipe 3, the flexible sleeve 2 and the outer walls of the rubber ring 4 abut against each other, and the flexible sleeve 2 may be deformed so that the flexible sleeve 2 and the rubber ring 4 abut against each other, reducing the fitting gap between the flexible sleeve 2 and the outer walls of the rubber ring 4.
[0047] The above-mentioned swimming pool water inlet water-stop device is provided by arranging a flexible sleeve 2 at the water inlet 11 and arranging the water inlet pipe 3 inside the flexible sleeve 2, so that the flexible sleeve 2 provides an additional layer of protection for the water inlet pipe 3, which can avoid mutual friction between the water inlet pipe 3 and the inner edge of the water inlet 11, thereby extending the service life of the water inlet pipe 3; by arranging a rubber ring 4 in the gap 21 between the flexible sleeve 2 and the water inlet pipe 3, so that the rubber ring 4 blocks the gap 21 between the flexible sleeve 2 and the water inlet pipe 3, thereby sealing the gap between the water inlet pipe 3 and the inner edge of the water inlet 11, avoiding the water in the swimming pool 1 from leaking from the gap between the water inlet pipe 3 and the water inlet 11, thereby ensuring the structural integrity and service life of the swimming pool 1.
[0048] like Figure 2-Figure 4 As shown, the flexible sleeve 2 is connected to a flange assembly 5, which is connected to the bottom wall of the swimming pool 1. By providing the flange assembly 5 connected to the bottom wall of the swimming pool 1 and the flexible sleeve 2, the bottom wall of the swimming pool 1 is fixed to the flexible sleeve 2 via the flange assembly 5, thereby increasing the firmness and reliability of the flexible sleeve 2 at the water inlet 11.
[0049] The upper end of the flexible sleeve 2 is located at the water inlet 11, and the lower end of the flexible sleeve 2 is connected to a flange assembly 5. The flange assembly 5 is located outside the swimming pool 1 and is connected to the outer wall of the swimming pool 1. Since the flange assembly 5 is generally a metal component, if the flange assembly 5 is located inside the swimming pool 1, it may frequently come into contact with water and rust. This will not only easily reduce the reliability of the flexible sleeve 2, but also easily contaminate the water in the swimming pool 1.
[0050] The flange assembly 5 is provided with a flange opening for the water inlet pipe 3 to pass through. The flange opening is arranged along the length direction of the flexible sleeve 2 and passes through the first flange 51 and the second flange 52; the inner diameter of the flange opening is smaller than the outer diameter of the second end to prevent the rubber ring 4 from escaping from the flange opening to the gap 21 between the flexible sleeve 2 and the water inlet pipe 3.
[0051] like Figure 3-Figure 5 As shown, the flange assembly 5 includes a first flange 51 and a second flange 52. The first flange 51 is connected to the lower end of the flexible sleeve 2, and the second flange 52 is installed on the outer wall of the bottom of the swimming pool 1. The first flange 51 and the second flange 52 are connected to each other by fasteners. It should be noted that the fasteners are components such as bolts or screws.
[0052] In some embodiments, the first flange 51 and the flexible sleeve 2 are designed as an integral unit by injection molding or other methods.
[0053] like Figure 5As shown, the second flange 52 is provided with a protrusion 521, which is located on the side of the second flange 52 facing the upper end of the flexible sleeve 2, and is arranged in the gap 21 when the second flange 52 is connected with the first flange 51. The protrusion 521 abuts against the end of the rubber ring 4 facing the second flange 52, and is used to press the rubber ring 4 into the gap 21.
[0054] Since the flexible sleeve 2 and the water inlet pipe 3 produced by different manufacturers generally have different sizes, which will cause the gap between the flexible sleeve 2 and the water inlet pipe 3 to be different, resulting in different sealing effects of the rubber ring 4 on the gap 21 between the flexible sleeve 2 and the water inlet pipe 3. The rubber ring 4 is designed as a circular truncated cone shape, which can make the gap between the flexible sleeve 2 and the water inlet pipe 3 be fully filled.
[0055] Specifically, as shown in the drawings, Figure 6 The rubber ring 4 is in the shape of a circular truncated cone, and includes a first end and a second end. The outer diameter of the first end is smaller than that of the second end, and the second end is arranged close to the end of the flexible sleeve 2 connected with the flange assembly 5.
[0056] In some embodiments, the second end abuts against the protrusion 521, and when the flange assembly 5 is connected with the bottom wall of the swimming pool 1 through the fastener, the rubber ring 4 is pressed into the gap 21 between the flexible sleeve 2 and the water inlet pipe 3 under the action of the fastener and the flange assembly 5, so as to ensure the sealing effect of the rubber ring 4 on the gap 21 between the flexible sleeve 2 and the water inlet pipe 3.
[0057] It should be noted that the rubber ring 4 is made of rubber or silicone.
[0058] The water inlet 11 is arranged on the bottom of the swimming pool 1, and penetrates the bottom wall of the swimming pool 1 in the vertical direction. The thickness of the bottom wall of the swimming pool 1 is H, and the length of the flexible sleeve 2 is L. L and H satisfy the relationship: L≥H.
[0059] The above-mentioned water inlet sealing device for swimming pool further includes a sealing member arranged between the flexible sleeve 2 and the water inlet pipe 3, which is used to seal the gap 21 between the flexible sleeve 2 and the water inlet pipe 3, so as to prevent the water in the swimming pool 1 from leaking through the gap between the water inlet pipe 3 and the water inlet 11.
[0060] In some embodiments, the sealing member is made of waterproof material, and the inner wall of the upper end of the flexible sleeve 2 and the outer wall of the upper end of the water inlet pipe 3 are sealed by the waterproof material.
[0061] In other embodiments, the method of using waterproof material to seal the gap 21 between the flexible sleeve 2 and the water inlet pipe 3 is: first, use the leak-stopping spirit to block 5 cm, then use RT-S new single-group polymer waterproof coating to fill 10 cm, and after the RT-S is dry, use the leak-stopping spirit to block 5 cm again; finally, use RT-S waterproof coating to paint a diameter of 10-15 cm to better combine the outer wall of the water inlet pipe 3 with the inner wall of the flexible sleeve 2.
[0062] The plugging member is disposed near the upper end of the flexible sleeve 2, and the rubber ring 4 is disposed near the lower end of the flexible sleeve 2. The plugging member blocks the upper gap 21 between the flexible sleeve 2 and the water inlet pipe 3, and the rubber ring 4 blocks the lower gap 21 between the flexible sleeve 2 and the water inlet pipe 3, thereby ensuring a water-stopping effect on the gap between the water inlet pipe 3 and the water inlet 11.
[0063] The upper end of the flexible sleeve 2 is flush with the outlet end of the water inlet pipe 3 and the inner side of the bottom wall of the swimming pool 1 to prevent the flexible sleeve 2 and / or the water inlet pipe 3 from protruding from the inner side of the bottom wall of the swimming pool 1 and tripping people in the swimming pool 1.
[0064] The installation steps of the above-mentioned swimming pool water inlet water stop device are as follows: put the rubber ring 4 on the outer periphery of the water inlet pipe 3, so that the first end of the rubber ring 4 is set toward the water outlet of the water inlet pipe 3; set the first flange 51 at the lower end of the flexible sleeve 2, and put the flexible sleeve 2 on the outer periphery of the water inlet pipe 3, wherein the end of the flexible sleeve 2 without the first flange 51 is set corresponding to the water outlet of the water inlet pipe 3; then set the blocking piece in the upper end gap 21 between the flexible sleeve 2 and the water inlet pipe 3, and then insert the upper end of the flexible sleeve 2 into the Insert the flexible sleeve 2, the water inlet pipe 3, and the sealing member into the water inlet 11 of the swimming pool 1 so that the upper end of the flexible sleeve 2, the upper end of the water inlet pipe 3, and the upper end of the sealing member are flush with the outer edge of the side of the water inlet 11 of the swimming pool 1 facing the interior of the swimming pool 1; then, set the rubber ring 4 at the lower end of the gap 21 between the flexible sleeve 2 and the water inlet pipe 3, and connect the first flange 51 to the second flange 52 set on the outer wall of the bottom of the swimming pool 1 through fasteners. The rubber ring 4 is pressed into the gap 21 between the flexible sleeve 2 and the water inlet pipe 3 under the action of the fasteners and the flange assembly 5.
[0065] The above-mentioned swimming pool water inlet water-stopping device can not only stop the gap between the water inlet pipe 3 and the water inlet 11, preventing the water in the swimming pool 1 from leaking from the gap between the water inlet pipe 3 and the water inlet 11, but also protect the water inlet pipe 3, avoiding friction between the water inlet pipe 3 and the inner edge of the water inlet 11, thereby extending the service life of the water inlet pipe 3; and the overall structure is simple, easy to arrange and install, saving labor costs; the material cost used for each component is low.
[0066] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0067] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
