[0029] Please see Figure 1-5This utility model provides a technical solution: a leak detection and early warning device for the safety of chemical equipment, including a base 1, and a multi-directional transmission device is provided at the top of the base 1;

[0031] One end of the first cylinder 2 is welded to the top of the base 1. The external power supply to the device is connected, and the first cylinder 2 is adjusted to a suitable height. The first geared motor 3 is then adjusted to rotate. The first geared motor 3 is fixedly connected to the inner cavity of the top of the first cylinder 2. The output end of the first geared motor 3 is rotatably connected to the second cylinder 4. The rotation of the first geared motor 3 drives the second cylinder 4 to rotate in a suitable direction.

One end of the inner cavity of the second cylinder 4 is fixedly connected to the second geared motor 5. The output end of the second geared motor 5 is rotatably connected to the first cylindrical cylinder 6. The angle between the second cylinder 4 and the first cylindrical cylinder 6 is 90°. The bottom end of the inner cavity of the first cylindrical cylinder 6 is fixedly connected to the first... The output end of the third geared motor 7 is rotatably connected to the first inclined rod 8. The third geared motor 7 under the first cylindrical tube 6 drives the first inclined rod 8 to rotate to the appropriate direction. The other end of the first inclined rod 8 is fixedly connected to the second cylindrical tube 9. The first inclined rod 8 drives the second cylindrical tube 9 to rotate to the appropriate direction. The second cylindrical tube 9 is fixedly connected to one side of the second cylindrical tube 9. The output end of the fourth geared motor 10 is rotatably connected to the second inclined rod 11. The other end of the second inclined rod 11 is fixedly connected to the position adjustment device. The second cylindrical tube 9 is rotated to the appropriate direction by the fourth geared motor 10, so that the leakage detection and early warning device 22 can rotate in all directions and can detect leaks at different locations.

[0032] The position adjustment device includes a motor base 12, a fifth reduction motor 13, a connecting rod 14, a slider 15, a slide rail 16, a horizontal plate 17, a semi-circular slot 19, a rectangular frame 18, a groove 26, a cylindrical rod 23, a spring 25, a roller 24, a support plate 21, and a support block 20.

[0033] The other end of the second diagonal rod 11 is fixedly connected to a motor base 12. The top of the motor base 12 is fixedly connected to a fifth reduction motor 13. When the fifth reduction motor 13 is started, one end of a connecting rod 14 is welded to the output end of the fifth reduction motor 13, and the other end of the connecting rod 14 is welded to a slider 15. The fifth reduction motor 13 drives the slider 15 to rotate clockwise. The slider 15 is cylindrical in shape, and a slide rail 16 is fitted onto the outer wall of the slider 15. The slider 15, through its cooperation with the slide rail 16, causes the slide rail 16 to move to the right. The slide rail 16 is formed by welding two upper and lower semicircular rings to a vertical rod in the middle. A horizontal plate 17 is welded to the center of the outer right side of the slide rail 16. The slide rail 16 drives the leak detection and early warning device 22 to move to the right via the horizontal plate 17, thus enabling the movement of the leak detection and early warning device 22. When the leak detection and early warning device 22 moves to the appropriate position, the fifth reduction motor 13 stops. Semi-circular slots 19 are symmetrically opened at the center of the outer walls at both ends of the horizontal plate 17. The semi-circular slots 19 are opened at intervals of 1cm on the outer walls at both ends of the horizontal plate 17.

The center of the right outer wall of the motor base 12... A support plate 21 is welded to the position, and the center of the support plate 21 is bolted to the rectangular frame 18.

A leak detection and early warning device 22 is provided on one side of the top of the horizontal plate 17. The spring 25, which is in a compressed state, returns to its original state. The spring 25 pushes the roller 24 into the semi-circular hole grooves at both ends of the horizontal plate 17 through the cylindrical rod 23, so as to realize the locking of the horizontal plate 17. At this time, the leak detection and early warning device 22 completes the moving locking, so as to realize the monitoring and detection of deeper positions by the leak detection and early warning device 22.

[0034] As a preferred embodiment, both the first diagonal bar 8 and the second diagonal bar 11 are formed by two equilateral triangular blocks connected to an axis. The included angle between the rods connected to the axes at both ends of the first diagonal bar 8 and the second diagonal bar 11 is 135°. The first diagonal bar 8 and the second diagonal bar 11 are the same size.

[0035] As a preferred option, the leak detection and warning device 22 is further detachably connected to the top side of the horizontal plate 17, which facilitates the disassembly, maintenance and replacement of the leak detection and warning device 22.

[0036] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0037] When this device is needed for leak detection, first connect the external power supply. After adjusting the first cylinder 2 to an appropriate height, adjust the first reduction motor 3 to rotate. The rotation of the first reduction motor 3 will drive the second cylinder 4 to rotate in an appropriate direction. Then, adjust the second cylinder 4 to an appropriate distance. At this point, the third reduction motor 7 below the first cylindrical cylinder 6 will drive the first inclined rod 8 to rotate in an appropriate direction. The first inclined rod 8 will drive the second cylindrical cylinder 9 to rotate in an appropriate direction. The second cylindrical cylinder 9 will then drive the second inclined rod 11 to rotate in an appropriate direction via the fourth reduction motor 10, achieving omnidirectional rotation of the leak detection and warning device 22. This allows for leak detection at different locations. At this time, the fifth reduction motor will be activated. The fifth reduction motor 13 drives the slider 15 to rotate clockwise. The slider 15, in cooperation with the slide rail 16, causes the slide rail 16 to move to the right. The slide rail 16, through the horizontal plate 17, drives the leak detection and early warning device 22 to move to the right, thus enabling the leak detection and early warning device 22 to move. When the leak detection and early warning device 22 moves to the appropriate position, the fifth reduction motor 13 stops, and the spring 25, which is in a compressed state, returns to its original position. The spring 25, through the cylindrical rod 23, pushes the roller 24 into the semi-circular holes at both ends of the horizontal plate 17, thus achieving the locking of the horizontal plate 17. At this time, the leak detection and early warning device 22 completes the moving locking, realizing the monitoring and detection of deeper locations by the leak detection and early warning device 22. This design has strong applicability and is beneficial for widespread use.
