Obviously, the battery module 13 is electrically connected to the sensor module 12 and the antenna 14 respectively to realize the collection, storage and transmission of the pressure data and temperature data of the gas well to be collected. Of course, in practical applications, the intelligent plunger device can also be used to monitor data of other physical quantities. Furthermore, in order to accurately monitor the temperature data and pressure data of the gas well to be collected, as well as acceleration and other data, that is, by integrating the temperature sensor and the pressure sensor or the acceleration sensor into different PCB boards, the sensor module 12 is divided into a first sensor unit (for example, the first sensor unit can be a temperature sensor, a pressure sensor or an acceleration sensor) and a second sensor unit (for example, the second sensor unit can be a temperature sensor, a pressure sensor or an acceleration sensor). With reference to the above, the sensor module 12 is configured in the plunger body 110. The structure of the plunger body 110 is described in detail below in conjunction with the sensor module 12. The plunger body 110 includes a first section 1100 and a second section 1101 that are plugged into each other, and the first sensor unit and the battery module 13 are respectively disposed in the first section 1100 and the second section 1101.

[0032] In the present invention, the plunger body 11 also includes an antenna seat 111 for mounting the antenna 14, and the antenna seat 111 is inserted into one end of the plunger sleeve 10 close to the sensor module 12, and the antenna 14 is electrically connected to the sensor module 12. In order to prevent the antenna 14 from shaking during the movement of the intelligent plunger device. A plurality of grooves are also provided on the surface of the antenna seat 111, so that the salvage head can salvage the intelligent plunger device during the upward movement of the intelligent plunger device, and the salvage head can be connected to the salvage head.

[0033] The utility model also includes a fastening screw 16 and a protective seat 15, and the protective seat 15 is connected to the end of the plunger sleeve 10 away from the sensor module 12 through the fastening screw 16.

[0035] Embodiment: When in use, the intelligent plunger device is dropped into the accumulated liquid in the pipeline through the drainage and gas production wellhead. The intelligent plunger device falls quickly, and the sensor module 12 inside the plunger body 110 is used to monitor the changes in acceleration, pressure, temperature, etc. during the movement of the plunger. The acceleration of the intelligent plunger device will change greatly at the moment of entering the water. The acceleration sensor inside the sensor module 12 monitors the signal of the acceleration change of the intelligent plunger device when entering the water; the pressure sensor monitors the pressure of the intelligent plunger device during the movement; the temperature sensor monitors the temperature of the intelligent plunger device during the movement. After a certain period of time after the intelligent plunger device enters the water, the falling speed of the intelligent plunger device drops rapidly to 0; at this time, the intelligent plunger device is suspended in the bottom well liquid, and there is a certain height of water column above it, generally 10-210 meters, which will vary according to different well conditions; at this time, the drainage gas production well will generate a higher air pressure at the bottom of the intelligent plunger device; the bottom well pressure pushes the intelligent plunger device and the liquid on the top of the intelligent plunger device to the wellhead, and the water and air flow through the gaps between the multiple annular protrusions 1020 on the surface of the plunger sleeve 10, and when they contact the annular surface of the annular protrusion 1020, they will also push the entire intelligent plunger device upward. The liquid on the top of the intelligent plunger device flows away through the bypass pipeline, and the wellhead device salvages the plunger through the salvage head to return to the initial state; when the bottom well liquid increases again, the intelligent plunger device is put in, and the above process is repeated, and the cycle is repeated until the bottom well liquid is discharged to ensure the normal production of the natural gas well.
