Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5This utility model provides a technical solution: an expansion tank leakage detection device, including an expansion tank body 10, a support leg 3 fixedly connected to the outer circumference of the expansion tank body 10, a detection mechanism provided on the top of the support leg 3, the detection mechanism including a liquid level sensor 18, a reinforcing ring 20 and a pressure sensor 21, a crossbar 22 fixedly connected to the top of the liquid level sensor 18, one end of the crossbar 22 fixedly connected to the inner wall of a sealing cover 1, one side of the inner wall of the sealing cover 1 fixedly connected to the pressure sensor 21, and the pressure sensor 21 electrically connected to a pressure sensor 19. One side of the device 19 is fixedly connected to the inner ring surface of the reinforcing ring 20, and the outer ring surface of the reinforcing ring 20 is fixedly connected to the inner wall of the expansion tank body 10. An electrical control box 11 is fixedly connected to the outer ring surface of the expansion tank body 10. The electrical control box 11 is electrically connected to the pressure sensor 19. An audible and visual alarm 12 is fixedly connected to one side of the electrical control box 11. The audible and visual alarm 12 is electrically connected to the liquid level sensor 18. A sealing ring 2 is fixedly connected to the top of the expansion tank body 10. The inner wall of the sealing ring 2 is threadedly connected to the sealing cover 1. A sealing ring 23 is fixedly connected to the inner wall of the sealing cover 1.

[0025] The expansion tank body 10 is supported and reinforced by the support leg 3. The crossbar 22 assists in the installation of the liquid level sensor 18 inside the sealing cover 1, allowing the sensor to detect changes in the liquid level inside the expansion tank body 10. The sealing cover 1 assists in the installation and use of the pressure sensor 21, allowing the sensor to detect pressure changes at the top of the expansion tank body 10. The reinforcing ring 20 supports and reinforces the installation of the pressure sensor 19. The pressure sensors 19 and 21 can respectively monitor different positions of the expansion tank body 10. The pressure is monitored to help determine whether there is a leak in the expansion tank body 10. Combining the detection results of liquid level change with the detection results of pressure change can improve the accuracy of leak detection. When a leak is detected, an audible and visual alarm 12 will be triggered to facilitate timely detection by staff and reduce the interference of the expansion tank body 10 with the use of the leak. The sealing ring 23 can improve the internal sealing of the expansion tank body 10. The sealing ring 2 can assist the connection between the sealing cover 1 and the expansion tank body 10, and facilitate the installation and removal of the sealing cover 1 on the top of the expansion tank body 10.

[0026] Please see Figures 1-3A connecting pipe 7 is fixedly connected to the top of the sealing cap 1. A feed inlet 8 is provided on one side of the connecting pipe 7. The bottom of the feed inlet 8 is fixedly connected to the sealing cap 1. A bevel gear 2 9 is rotatably connected to the outer ring surface of the expansion tank body 10. A bevel gear 1 5 meshes with the top of the bevel gear 2 9. One end of the bevel gear 1 5 is rotatably connected to the expansion tank body 10. The output shaft of the motor 6 is fixedly connected to one side of the bevel gear 1 5. A support frame 4 is fixedly connected to the bottom of the motor 6. One side of the support frame 4 is fixedly connected to the outer ring surface of the expansion tank body 10. A connector 13 is fixedly connected to the bottom of the bevel gear 2 9. An electric push rod 14 is fixedly connected to one side of the connector 13. A connecting frame 17 is fixedly connected to one end of the electric push rod 14. The top of the connecting frame 17 is slidably connected to the connector 13. The connecting frame 17 is L-shaped, and a vision inspection component 16 is fixedly connected to the top of the connecting frame 17. A camera 15 is fixedly connected to one end of the vision inspection component 16.

[0027] The feed inlet 8 facilitates the injection of liquid into the expansion tank body 10. The support frame 4 supports the bottom of the motor 6, improving the stability of the motor 6 during installation and use. The motor 6 drives the first bevel gear 5 to rotate stably. The meshing between the first bevel gear 5 and the second bevel gear 9 drives the second bevel gear 9 to rotate on the outer ring surface of the expansion tank body 10, thereby changing the position of the connecting piece 13. The electric push rod 14 connects the connecting piece 13 and the connecting frame 17, allowing adjustment of the height of the connecting frame 17, which in turn changes the height of the camera 15 and the vision detection component 16. When the second bevel gear 9 rotates, the connecting piece 13 and the camera 15 rotate with the second bevel gear 9, thereby changing the range of image acquisition by the camera 15, facilitating the rapid location of leaks around the expansion tank body 10. The connecting frame 17 supports the bottom of the vision detection component 16, improving the stability of the vision detection component 16 during lifting and rotation.

[0028] The overall working principle is as follows: First, pressure sensor 19 and pressure sensor 21 are used to detect the air pressure on the side wall and top of the expansion tank body 10, respectively. Under normal operating conditions, the pressure inside the expansion tank body 10 is within a relatively stable range. When a leak occurs in the expansion tank body 10, the internal pressure will gradually decrease. At this time, pressure sensor 19 and pressure sensor 21 can detect the pressure change and send the detection results to the PLC controller in the electrical control box 11. When the pressure drop exceeds a predetermined threshold, the controller activates the level sensor 18 to detect the liquid level inside the expansion tank body 10. When the liquid level drops and falls below the set minimum liquid level, the PLC controller controls the level sensor 18, pressure sensor 19, and pressure sensor 21. The data collected by device 21 is comprehensively analyzed and judged, driving the audible and visual alarm 12 to sound an alarm, indicating that the expansion tank body 10 has leaked. At this time, motor 6 drives bevel gear 5 to rotate, bevel gear 5 drives bevel gear 9 to rotate along the expansion tank body 10, driving connecting piece 13 to rotate synchronously with bevel gear 9. Electric push rod 14 drives connecting frame 17 to move down, and visual detection component 16 moves down synchronously with connecting frame 17. The operating height of visual detection component 16 and camera 15 can be adjusted. When bevel gear 9 rotates, camera 15 acquires image information of the outer surface of expansion tank body 10. The processed image is sent to an external control terminal through visual detection component 16. The control terminal identifies the image and thus locates the leak point.
