[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application discloses a cooling tower water pump sealing structure. Figure 1 and Figure 2 A cooling tower water pump sealing structure includes a water pump body 1 and a tubular water receiving pipe 2, and a tubular water inlet 3 and a tubular water outlet 4 are fixedly connected on the outer surface of the water pump body 1, so that water for cooling flows into the water pump body 1 from the water inlet 3 and then flows out from the water outlet 4, an annular first connecting ring 5 is fixedly connected on the outer surface of the water outlet 4, and an annular second connecting ring 6 is fixedly connected on the outer surface of the water receiving pipe 2, and the second connecting ring 6 is snap-connected to the side surface of the first connecting ring 5, so that the water receiving pipe 2 and the water outlet 4 are quickly sealed and connected, so as to quickly inspect and maintain them, and secondly, an annular first rubber ring 7 is fixedly connected on the side surface of the second connecting ring 6, and the inner wall of the first rubber ring 7 is in close contact with the outer surface of the water receiving pipe 2, and the outer surface of the first rubber ring 7 is in close contact with the water outlet 4. The inner wall of the water outlet 4 slides relatively, so that when the water receiving pipe 2 and the water outlet 4 are connected, the gap between the water receiving pipe 2 and the water outlet 4 is sealed by the first rubber ring 7, thereby increasing the sealing of the connection and preventing water leakage. The trapezoidal cross-sectional shape of the first rubber ring 7 is designed to facilitate the rapid sliding of the water receiving pipe 2 into the inner wall of the water outlet 4, and a ring-shaped second rubber ring 8 is fixedly connected to the side surface of the second connecting ring 6, and the side surface of the second rubber ring 8 is closely attached to the side surface of the water outlet 4, so that when the water receiving pipe 2 and the water outlet 4 are connected, the second rubber ring 8 is squeezed to generate reverse elastic force, thereby sealing the gap between the first connecting ring 5 and the second connecting ring 6, thereby achieving double sealing, and further strengthening the sealing of the connection, ensuring the normal operation of the water pump, and extending the service life of the water pump.

[0021] Reference Figure 2 A ring-shaped mounting groove 9 is provided on the side surface of the second connecting ring 6, a ring-shaped second rubber ring 8 is fixedly connected to the inner wall of the mounting groove 9, and a plurality of cylindrical groove-shaped mounting holes 10 are provided inside the second rubber ring 8, and the plurality of mounting holes 10 are distributed in a centrally symmetrical shape, and the inner walls of the plurality of mounting holes 10 are fixedly connected with reset springs 11, so that when the water receiving pipe 2 is connected to the water outlet 4, the second rubber ring 8 is squeezed, and the reset effect of the plurality of reset springs 11 causes the second rubber ring 8 to squeeze the first connecting ring 5, thereby effectively sealing the gap between the first connecting ring 5 and the second connecting ring 6, and realizing secondary sealing.

[0022] Reference Figure 3 Two arc-shaped positioning grooves 12 are provided on the side surface of the first connecting ring 5, and two arc-shaped positioning plates 13 are fixedly connected to the side surface of the second connecting ring 6, and the positioning plates 13 slide relative to the inner wall of the positioning groove 12, so that when connecting the water receiving pipe 2 and the water outlet 4, the positioning plates 13 can be slid into the inner wall of the positioning groove 12, so that the connection can be completed accurately, the deviation can be avoided, and the connection efficiency is improved;

[0023] Secondly, a hole-shaped through hole 14 is penetrated on the upper surface of the second connecting ring 6, and a groove-shaped limiting groove 15 is opened on the side surface of the first connecting ring 5. The inner wall of the limiting groove 15 is elastically slidably connected with a block-shaped limiting block 16 through a spring, and the limiting block 16 can be engaged with the inner wall of the through hole 14, so as to press the limiting block 16 to make it located on the inner wall of the limiting groove 15, and the spring is in a compressed state. Subsequently, after the positioning plate 13 is slid into the inner wall of the positioning groove 12, the limiting block 16 is released. At this time, the limiting block 16 rebounds and engages with the inner wall of the through hole 14 under the resetting action of the spring, thereby completing the quick connection between the water receiving pipe 2 and the water outlet 4, improving the connection efficiency, and facilitating its inspection and maintenance.

[0024] The implementation principle of the sealing structure of a cooling tower water pump in the embodiment of the present application is as follows: when the docking water pipe 2 is connected to the water outlet 4, the first rubber ring 7 is slowly slid in close to the inner wall of the water outlet 4, and the gap between the docking water pipe 2 and the water outlet 4 is sealed by the first rubber ring 7 to increase the sealing of the connection, and then the limit block 16 is pressed to be located on the inner wall of the limit groove 15, and the spring is in a compressed state, and then after the positioning plate 13 is slid into the inner wall of the positioning groove 12, the limit block 16 is released, and at this time, the limit block 16 rebounds and engages with the inner wall of the through hole 14 under the reset action of the spring, thereby completing The quick connection between the water receiving pipe 2 and the water outlet 4 improves the connection efficiency and facilitates the inspection and maintenance thereof. At the same time, the second rubber ring 8 and the plurality of reset springs 11 are squeezed by the first connecting ring 5 and the second connecting ring 6. Under the reset action of the plurality of reset springs 11, the second rubber ring 8 produces reverse extrusion on the first connecting ring 5, thereby effectively sealing the gap between the first connecting ring 5 and the second connecting ring 6, realizing the double sealing of the connection, thereby further strengthening the sealing of the connection, ensuring the normal operation of the water pump, preventing water leakage, and extending the service life of the water pump.
