Problems solved by technology

[0003] The technical problem solved by the present invention is that it is impossible to realize the same-direction connection in the vertical direction and the directional connection in the lateral direction of the multi-stage vibration detection device in the well, and the collected signals cannot be compared and superimposed on the same level, resulting in inaccurate received signals and inaccurate signal analysis. For the technical problem that the vibration detection devices in multi-level wells interfere with each other and cannot be used, a method is provided that can realize the same direction connection in the vertical direction and the directional connection in the lateral direction of the vibration detection devices in multi-level wells. Multiple sets of acquisition signals can be equivalently compared and superimposed. The receiving signal is more accurate, the signal analysis is more accurate, the multi-level well vibration detection device does not interfere with each other, and the well vibration detection device that can work independently is shock-absorbing connector

Abstract

The invention discloses a shock absorption connector for a shock detection device in a well and relates to a shock detection device in a well. Connecting bodies are a left connecting body and a right connecting body with the same structure; a left connecting claw is uniformly distributed at one end of the left connecting body; a left connecting lug is arranged at the tail end of the left connecting claw; a right connecting claw is uniformly distributed at one end of the right connecting body; a right connecting lug is arranged at the tail end of the right connecting claw; the left connecting claw and the right left connecting claw on the left connecting body and the right connecting body are inserted in a staggered mode; two semicircular-ring left flange plates and two semicircular-ring right flange plates are arranged between the left connecting lug and the right connecting lug; fixed rods are arranged between the left flanges and the right flanges; shock absorption pads are arrangedon the fixed rods; a left connecting notch and a left connecting hole are formed at the other end of the left connecting body; and a right connecting notch and a right connecting hole are formed at the other end of the right connecting body. Multi-level shock detection devices in the well do not interfere one another and can independently work, the acquired signals can be equivalently contrasted and superposed, the signals are accurately received, the signals are analyzed accurately, and the connector is applied to connecting the multi-level shock detection devices in the well.

Description

technical field [0001] The invention relates to a vibration detection device in a well, in particular to a shock-absorbing connector for a vibration detection device in a well. Background technique [0002] We know that the existing well vibration detection devices are connected by soft ropes between the well vibration detection devices, which is a flexible connection, and it is impossible to realize the same direction connection in the vertical direction and the directional connection in the lateral direction of the multi-level well vibration detection devices , the collected signals cannot be compared and superimposed on the same level, resulting in inaccurate received signals and inaccurate signal analysis; or a hard connection is used between the vibration detection devices in the well, which causes mutual interference between the multi-level vibration detection devices in the well and cannot work independently, resulting in the final The signal analysis for is inaccurat...
