By arranging the sealing plate 8 at the bottom of one side of the inner wall of the vacuum chamber 7, when water is injected into the electrode body 1, part of the water can be introduced into the sealing plate 8, and then the sealing cover 9 and the cover 13 are tightened, and the electrode body 1 is shaken to fully mix the gel and the water. At the same time, observe whether there are water droplets in the insulating tube 5 to confirm the sealing performance of the vacuum chamber 7. Embodiment

[0030] As Figures 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a sealing cover 9 is inserted at the bottom of the electrode body 1. A rotating shaft 10 is rotatably connected to the inner wall of the sealing cover 9. A dial block 11 is fixedly connected to the bottom of the rotating shaft 10. A stirring frame 12 is fixedly connected to the top of the rotating shaft 10. A cover 13 is threadedly connected to the bottom of one side of the outer wall of the insulating tube 5.

By shifting the shifting block 11 provided at the bottom of the rotating shaft 10, a stirring frame 12 provided at the top of the rotating shaft 10 is driven to stir the gel in the electrode body 1, so that the gel can be more evenly covered on the metal rod 2, thereby improving the measurement accuracy of the reference electrode. Subsequently, the sealing cover 13 is installed at the bottom of the insulation tube 5, and the sealing cover 9 is limited by the sealing cover 13. At the same time, a slider 15 provided on the outer wall of the sealing cover 13 is shifted to move the inner wall of the slider 15 on the surface of the support rod 14 provided in the middle part of the inner wall of the sealing cover 13, thereby driving the support blocks 16 provided at the four corners of the outer wall of the slider 15 to break away from the limit of the sealing cover 13, and the electrode body 1 is supported by the support blocks 16, which further solves the problem that when measuring the circuit outdoors, in order to stabilize the measurement data of the reference electrode, it is often necessary to dig a pit or use stones to fix the reference electrode to keep the reference electrode in a vertical state. Example

[0032] like Figures 1-6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a block 17 is fixedly connected to the middle part of one side of the outer wall of the insulation tube 5, a spring winch 18 is rotatably connected to one side of the inner wall of the block 17, a cable 19 is fixedly connected to the outer wall of the spring winch 18, one end of the cable 19 is fixedly connected to an insert block 20, and one end of the insert block 20 is plugged into the inner wall of the block 17.

[0033] In this embodiment, a stopper 17 is provided in the middle of one side of the outer wall of the insulation tube 5, and a spring capstan 18 is provided on one side of the inner wall of the stopper 17. When the reference electrode needs to be fixed on the pipeline, the cable 19 provided on the outer wall of the spring capstan 18 is pulled out, the pipeline is surrounded by the cable 19, and the plug block 20 provided at one end of the cable 19 is inserted into the stopper 17. The cable 19 is tightened by the rebound force of the spring capstan 18, thereby achieving the goal of fixing the reference electrode on the pipeline, further solving the problem that the reference electrode cannot be kept vertical when installed on the pipeline due to the complex outdoor environment, thereby affecting the accuracy of the reference electrode measurement data.

[0034] The working principle of the long-acting gel reference electrode measurement device is described in detail below.

[0035] like Figures 1-6As shown, by removing the sealing cover 13 and the sealing cover 9 from the electrode body 1 and injecting water into the electrode body 1, part of the water can be introduced into the sealing plate 8, then tightening the sealing cover 9, shaking the electrode body 1, so that the gel and water are fully mixed, and at the same time observing whether there are water droplets in the insulation tube 5, so as to confirm the sealing of the vacuum tank 7, and using the vacuum tank 7 to isolate the external heat, so as to effectively slow down the melting of the gel in the reference electrode, greatly extending the service life of the reference motor, by arranging the sealing cover 9 at the bottom of the electrode body 1, arranging the rotating shaft 10 on the inner wall of the sealing cover 9, and by toggling the dial block 11 arranged at the bottom of the rotating shaft 10, the top of the rotating shaft 10 is driven The stirring frame 12 is arranged to stir the gel in the electrode body 1, so that the gel can be more evenly covered on the metal rod 2, thereby improving the measurement accuracy of the reference electrode, and then the cover 13 is installed at the bottom of the insulation tube 5, and the sealing cover 9 is limited by the cover 13. At the same time, the slider 15 arranged on the outer wall of the cover 13 is moved to make the inner wall of the slider 15 move on the surface of the support rod 14 arranged in the middle of the inner wall of the cover 13, thereby driving the support blocks 16 arranged at the four corners of the outer wall of the slider 15 to break away from the limit of the cover 13, and the electrode body 1 is supported by the support blocks 16, which further solves the problem of measuring the reference electrode in the outdoor circuit. In order to ensure stable measurement data, it is often necessary to dig a pit or use stones to fix the reference electrode to keep the reference electrode in a vertical state. A cable 3 is set at one end of a metal rod 2, a conductive clamp 4 is set at one end of the cable 3, and the conductive clamp 4 is clamped on the measured circuit for measurement. An insulation tube 5 is set on the outer wall of the electrode body 1, and an aluminum foil tube 6 is set on the outer wall of the insulation tube 5. The aluminum foil tube 6 is used to reflect sunlight, thereby greatly reducing the temperature inside the reference electrode. This further solves the problem that since the long-acting gel reference electrode is often used outdoors, the gel in the reference electrode is easily melted by the external sunlight, thereby greatly reducing its use. In order to solve the problem of service life, a block 17 is set in the middle of one side of the outer wall of the insulation tube 5, and a spring capstan 18 is set on one side of the inner wall of the block 17. When the reference electrode needs to be fixed on the pipeline, the cable 19 set on the outer wall of the spring capstan 18 is pulled out, and the cable 19 is used to surround the pipeline. The plug block 20 set at one end of the cable 19 is inserted into the block 17, and the cable 19 is tightened by the rebound force of the spring capstan 18, so as to fix the reference electrode on the pipeline, which further solves the problem that the reference electrode cannot be kept vertical when installed on the pipeline due to the complex outdoor environment, thereby affecting the accuracy of the reference electrode measurement data.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
