[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0022] The present embodiment provides an improved swimming pool drainage device, and the structure is as shown in Figures 1 to 4As shown, the prominent problems existing in the traditional device are solved by optimizing the design. The device is composed of a drainage shell 1, a filter screen 2, a drainage valve body 3 and a valve body opening rod 4, and each component cooperates to realize efficient and safe drainage function.

[0023] Figure 1 And Figure 2 As shown, the drainage shell 1 is integrally formed by using corrosion-resistant engineering plastic and is fixed to the bottom of the swimming pool. A cylindrical plug-in groove 11 is arranged inside the shell, and the drainage valve body 3 is sleeved in the plug-in groove in a clearance fit manner. The top end surface of the valve body is lower than the top end surface of the shell, forming a hidden installation structure, which completely eliminates the risk of collision during use of the swimming pool.

[0024] Figure 2 As shown, the drainage valve body 3 is designed as a hollow structure, and a composite clamping structure is designed at the top. A circular central groove 31 is arranged at the center position, and six fixed long grooves 32 are uniformly distributed around the circular central groove 31. The operating end of the opening rod 4 is integrated with a spherical clamping block 41, which is guided and centered by the central groove 31. When the clamping block is turned into the fixed long groove 32, the valve body lifting operation can be completed by pulling the opening rod, and the whole process does not need diving operation.

[0025] Figure 2 And Figure 3 As shown, a circumferential first sealing ring 33 is arranged at the bottom of the outer wall of the drainage valve body 3, and forms a radial seal with the inner wall of the plug-in groove 11. At the same time, a trapezoidal second sealing ring 12 is arranged at the edge of the bottom of the plug-in groove, and forms an end face seal with the end face of the valve body.

[0026] An inner recessed arc-shaped fool-proof groove 34 is arranged at the top of the valve body, and the curved surface profile enables the operator to easily insert the spherical clamping block 41 into the central groove 31 on the shore.

[0027] A drainage pipe 5 is arranged at the bottom of the drainage shell 1, and an annular stop ring 51 is arranged on the inner wall of the drainage pipe 5. The filter screen 2 is arranged above the stop ring by buckling, and effectively intercepts impurities. The height of the stop ring is designed as 5mm, which ensures the stability of the filter screen and avoids excessive water flow resistance.

[0028] The drainage device is more safe to use by the hidden installation and shore-based operation design, and the drainage operation efficiency is improved.

[0029] Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art belong to the scope protected by the utility model.
