[0021] In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as there is no conflict between them.
[0022] Please see attached Figure 1 -Attached Figure 3 The utility model discloses a monitoring device for a piston accumulator, comprising a cylinder body 1, a piston plate 2 which can move up and down is arranged inside the cylinder body 1, a gas end cover 3 is installed at one end of the cylinder body 1, an oil end cover 4 is installed at the other end of the cylinder body 1, and a detection component 5 which can detect the movement of the piston plate 2 is also arranged outside the cylinder body 1;
[0023] The detection component 5 includes a magnetostrictive wire 501, a permanent magnet block 502, and an electron bin 503. The electron bin 503 is provided in two groups and is correspondingly installed on the outer wall of the cylinder body 1.

[0024] In one embodiment of the present invention: a fixing member 6 is also provided outside the cylinder body 1 to facilitate fixing the position of the cylinder body 1. The fixing member 6 includes a fixing ring 601 fixed to the outer wall at both ends of the cylinder body 1 and a fixing groove 602 opened in the fixing ring 601 and capable of placing a fixing device.
[0025] In one embodiment of the present utility model: the outer walls of the gas end cover 3 and the oil end cover 4 are both provided with threads, and the threads of the gas end cover 3 and the oil end cover 4 are threadedly connected to the inner wall of the cylinder body 1 .
[0026] In one embodiment of the present invention: the outer wall of the cylinder body 1 is also engraved with a font mark 7 for facilitating the distinction between the gas end cover 3 and the oil end cover 4 .
[0027] In one embodiment of the present invention: the electronic compartment 503 is electrically connected to a display capable of displaying data.
[0028] In one embodiment of the present invention: a connecting belt 8 for easy carrying is arranged outside the fixing ring 601. The connecting belt 8 is the same length as the fixing rings 601 at both ends. Fixing screws 9 are installed at the ends of the connecting belt 8. The connecting belt 8 can fix both ends to the surface of the fixing ring 601 through the fixing screws 9.
[0029] Embodiment 1
[0030] When the piston accumulator is working, by arranging detection devices inside and outside the cylinder body 1, when the internal piston plate 2 moves, the data will be transmitted to the detection device, and then transmitted to the external display screen through the detection device, thereby achieving the effect of detecting the movement of the piston plate 2.
[0031] Specifically, the electronic compartment 503 contains an electronic circuit for generating current pulses, which are transmitted along the magnetostrictive wire 501 and generate a rotating magnetic field. There is also a magnetostrictive wire 501 made of a special magnetostrictive material, such as an iron-nickel alloy (Fe-Ni alloy), and a permanent magnet block 502 fixed inside the piston plate 2. When the circuit in the electronic compartment 503 generates a current pulse, this pulse is transmitted along the magnetostrictive wire 501 and generates a rotating magnetic field. When this rotating magnetic field meets the permanent magnet block in the piston plate 2, a torsional stress wave will be generated on the magnetostrictive wire 501, and this torsional stress wave propagates at the speed of sound. When this wave propagates to the detection device in the electronic compartment 503, a termination pulse will be generated. By measuring the time difference between the start pulse and the termination pulse, the position of the magnetic ring can be accurately calculated, and the data will eventually be transmitted to the display, thereby realizing the measurement of displacement and solving practical problems.
[0032] Embodiment 2
[0033] By arranging the fixing member 6 outside the cylinder body 1, the piston accumulator can be well fixed when in use and will not move easily, thereby increasing its stability.
[0034] Specifically, when fixing the piston accumulator, a strap or other fixing device may be wrapped in the fixing groove 602 to fix the upper and lower parts of the cylinder body 1, thereby achieving a fixing effect.
[0035] Working principle:
[0036] First, wrap a band or other fixing device in the fixing groove 602 to fix the upper and lower parts of the cylinder body 1, thereby achieving a fixing effect, and then intermittently inject the corresponding gas and oil into the gas end cover 3 and the oil end cover 4. When the piston plate 2 starts to move, the electronic compartment 503 is started to generate a current pulse. When the circuit in the electronic compartment 503 generates a current pulse, this pulse is transmitted along the magnetostrictive wire 501 and generates a rotating magnetic field. When this rotating magnetic field meets the permanent magnet block 502 in the piston plate 2, a torsional stress wave will be generated on the magnetostrictive wire 501, and this torsional stress wave will propagate at the speed of sound. When this wave propagates to the detection device in the electronic compartment 503, a termination pulse will be generated. By measuring the time difference between the start pulse and the end pulse, the position of the permanent magnet block 502 can be accurately calculated, and finally the data can be transmitted to the display, thereby realizing the measurement of displacement and solving the practical problem. When the cylinder body 1 as a whole needs to be moved a short distance, it can only be manually transported to a transportation tool or directly moved to the destination. Since the two ends of the connecting belt 8 are fixed to the surface of the fixing ring 601 by fixing screws 9, the cylinder body 1 can be moved by the connecting belt 8 at this time, which is convenient for the user to carry and the entire workflow is completed.
