Description

Lifting power assisting device for underground long cable water temperature sensor of earthquake

Technical Field

The invention relates to the technical field of seismic observation, in particular to a lifting power assisting device for a water temperature sensor of a long cable under a seismic well.

Background

The water temperature observation is one of main observation means of the earthquake geophysical table network, the change of the underground water temperature at a certain depth below the water surface of an observation well along with time is recorded, and the water temperature dynamic change process is studied to well reflect the earthquake inoculation, occurrence and post-earthquake adjustment states. Seismic fluid observation wells are typically hundreds of meters or even more than a kilometer deep. The fluid observation wells are internally provided with sleeves, the diameter of each sleeve is generally 100-200 mm, and some seismic fluid observation wells adopt reducer sleeves. The water temperature sensor is installed in the fluid well, is used for observing the water under a certain depth for a long time, is connected to the equipment host through a long cable, and converts a physical quantity temperature signal into an electric signal, so that data acquisition, processing, storage and transmission are realized.

In actual water temperature observation, the matched probe cable connected with the water temperature sensor has the characteristics of heavy weight, small diameter and the like. Because the installation depth of the water temperature sensor is different, the length of the matched probe cable can be hundreds of meters or even more than one kilometer. Taking a SZW type water temperature instrument commonly used for an earthquake fluid station as an example, the probe has the size of phi 30 multiplied by 690mm, the weight of the probe cable can reach about 44kg when the length of the probe cable is 1000m, and the diameter of the cable is about 4 mm. The water temperature probe can be observed underground for a long time, faults are unavoidable, and the sensor needs to be updated or maintained in time so as not to influence the continuity rate of the station observation data.

However, in the operation process of lifting or lowering the water temperature probe, the situation that the underground sleeve is changed in diameter or is trapped in underground sludge or the like is caused, or the cables of the water temperature probes are mutually entangled, and the like exists, so that the conventional commercial coil winder and other products are difficult to meet the requirements, and the cable is easily broken, and the like. Therefore, at present, the water temperature sensor and the probe cable are lifted or lowered mostly by adopting a manual mode, and particularly, the lifting process of the long cable water temperature sensor is difficult and needs to be completed by cooperation of multiple people. In contrast, the manual water temperature probe lifting mode is high in reliability, but is time-consuming and labor-consuming, and is not consistent with the automation and intelligent level of modern high-speed development equipment. Therefore, a need exists for a lift booster for a seismic down-hole long cable water temperature sensor.
