The adjacent ends of the two water conservancy pipe main bodies 1 are movably contacted with both sides of the sealing ring 3 respectively. The threaded rotation sleeve is used to achieve the connection between the round box 2 and the water conservancy pipe main body 1 on the right side by a simple rotation. The provided sealing ring 3 is used to perform sealing work at the connection when it is pressed by the water conservancy pipe main body 1 on the right side.

[0025] A floating control component is fixedly installed on the bottom of the round box 2, and a water collecting cover 8 is embedded and fixed on the inner wall of the bottom of the round box 2, wherein a conical embedding hole is opened on the inner wall of the bottom of the round box 2 and is fixedly connected to the outer side of the water collecting cover 8. The bottom of the water collecting cover 8 extends to the bottom of the round box 2 and is connected and fixed with the floating control component. An alarm reminder component electrically connected to the floating control component is fixedly installed on the left side of the bottom of the round box 2. When the water collecting cover 8 leaks at the connection due to aging of the sealing ring 3 and other factors, the leaked water is collected. The floating control component is used to use the collected water to automatically trigger and control the alarm reminder component to open and perform the alarm reminder work.

[0026] Specifically, the threaded connection assembly includes an internal threaded sleeve 5 which is sealed and rotated in the round box 2, wherein the internal fixed sleeve of the round box 2 is provided with two sealed bearings, and the inner ring of the sealed bearing is fixedly sleeved with the outer side of the internal threaded sleeve 5, which plays the effect of sealing and rotating the internal threaded sleeve 5. The top and bottom of the internal threaded sleeve 5 are fixedly connected to the handle rod 6 located on the right side of the round box 2. The internal thread of the internal threaded sleeve 5 is screwed with the external threaded sleeve 4. The external threaded sleeve 4 is fixedly sleeved on the water conservancy pipeline body 1 on the right side. A threaded hole is opened on the inner wall of the top of the internal threaded sleeve 5, and a knob-type compression bolt 7 is screwed with the internal thread of the threaded hole. The knob-type compression bolt 7 is located above the external threaded sleeve 4 and cooperates with the external threaded sleeve 4; the internal threaded sleeve 5, the handle rod 6 and the external threaded sleeve 4 are coordinated, and the internal threaded sleeve 5 is rotated by operating the handle rod 6. The internal threaded sleeve 5 is screwed on the external threaded sleeve 4 and drives the external threaded sleeve 4 to move to the left. The external threaded sleeve 4 drives the water conservancy pipeline body 1 on the right to move to the left and presses the sealing ring 3 to achieve a convenient sealed connection between the two water conservancy pipeline bodies 1. The knob-type compression bolt 7 is used to squeeze the external threaded sleeve 4 by rotation after connection, so as to strengthen the locking of the internal threaded sleeve 5 to prevent rotation and loosening.

[0027] Furthermore, the floating control assembly includes a water collecting box 10 fixedly connected to the bottom of the round box 2 and a spring-loaded non-locking tact switch 11. The spring-loaded non-locking tact switch 11 is located in the water collecting box 10. An L-shaped tube 9 is fixedly connected between the right bottom of the water collecting box 10 and the bottom of the water collecting cover 8. A vertical pipe 14 is fixedly connected to the inner wall of the bottom of the water collecting box 10. A vertical rod 13 is slidingly sleeved in the vertical pipe 14. A hollow floating block 12 is fixedly connected to the top of the vertical rod 13. The hollow floating block 12 is located below the spring-loaded non-locking tact switch 11. A drain valve 17 is fixedly connected to the bottom of the left side of the water collecting box 10. An overflow hole is provided on the right inner wall of the water collecting box 10, which is located above the hollow floating block 12. The water collecting box 10, the spring non-locking touch switch 11, the vertical pipe 14, the vertical rod 13 and the hollow floating block 12 are coordinated. When leakage occurs at the connection due to aging of the sealing ring 3 and other factors, the leaked water flows downward and is concentrated in the water collecting cover 8, and is guided into the water collecting box 10 through the L-shaped tube 9. The water floats upward on the hollow floating block 12, and the hollow floating block 12 squeezes and touches the spring non-locking touch switch 11 upward. The drain valve 17 is provided for maintenance personnel to release the water in the water collecting box 10 later.

[0028] Furthermore, the alarm reminder component includes a battery 15 fixedly connected to the left side of the bottom of the round box 2, and a sound and light alarm 16 is fixed and electrically connected to the left side of the battery 15. The battery 15 is electrically connected to the spring non-locking touch switch 11, and the battery 15, the sound and light alarm 16 and the spring non-locking touch switch 11 are connected in sequence to form a circuit; the set battery 15 and the sound and light alarm 16 cooperate, and the sound and light alarm 16 is controlled to turn on by the touched spring non-locking touch switch 11, so as to achieve the effect of timely automatic alarm reminder when leakage occurs at the connection.

[0029] The method of use of this embodiment is as follows: when connecting, a person operates the internal threaded sleeve 5 to rotate forwardly through the handle rod 6, so that the internal threaded sleeve 5 is screwed onto the external threaded sleeve 4, and under the action of the screw connection of the two, the internal threaded sleeve 5 continues to rotate, driving the external threaded sleeve 4 to move left, and the external threaded sleeve 4 drives the water conservancy pipe body 1 on the right to move left and press the sealing ring 3, thereby realizing a tool-free and convenient sealing connection between the two water conservancy pipe bodies 1, and eliminating the need for personnel to use special tools to operate multiple bolts one by one, thereby improving the convenience and efficiency of connection; in addition, after the connection, the person can also rotate the knob-type pressing bolt 7 forwardly to squeeze it downward with the external threaded sleeve 4, thereby strengthening the locking of the internal threaded sleeve 5 to prevent rotation and loosening, and further improving the stability of the connection position;

[0030] When leakage occurs at the connection due to aging of the sealing ring 3 and other factors, the leaked water flows downward through the connection and is concentrated in the water collecting cover 8, and is guided into the water collecting box 10 through the L-shaped tube 9. The water floats upward on the hollow float 12, and the hollow float 12 drives the vertical rod 13 to slide upward in the vertical tube 14. At the same time, the hollow float 12 presses the spring non-locking touch switch 11 upward to touch it. The touched spring non-locking touch switch 11 controls the sound and light alarm 16 to turn on, realizing the effect of timely automatic alarm reminder when leakage occurs at the connection, so that personnel can know in time to carry out maintenance and adjustment work. When adjusting, first The knob-type compression bolt 7 is rotated upward to release the tight state with the external threaded sleeve 4. Then the personnel can directly operate the internal threaded sleeve 5 to rotate forward again through the handle rod 6, so as to drive the water conservancy pipe body 1 on the right side to move left again to squeeze the sealing ring 3 for sealing. The adjustment method of simple rotation is convenient for subsequent sealing adjustment work; during subsequent maintenance, the personnel can open the drain valve 17 to drain the water in the water collecting box 10, so that the hollow float 12 moves downward under the action of gravity, and releases the touch state of the spring non-locking light touch switch 11, thereby releasing the alarm state.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
