Throw-in type underwater monitoring equipment cable locking device

Abstract

The invention discloses a throw-in type underwater monitoring equipment cable locking device. The device comprises a rod-shaped aluminum product, a nylon loop, and a fixed screw; a main through hole is formed in the middle of the rod-shaped aluminum product from front to back, a semi-arc through hole is arranged at the front side end of the main through hole, and a screw hole is arranged in the lower middle part of the main through hole; a fixed screw is screwed in the screw hole, the nylon collar is sleeved in the main through hole, and one end of a cable connected with a throw-in type underwater monitoring equipment sensor probe is led to a back end of the rod-shaped aluminum product from the inner side of the semi-arc through hole and the nylon collar at the inner side of the main through hole, and the other end of the cable is connected with a throw-in type underwater monitoring equipment wireless data transmission mechanism, and the rod-shaped aluminum product is arranged on a well protection device matched with the throw-in type underwater monitoring equipment. Since the locking device cannot cause the cable bending dead angle and cannot directly contact with metal, the cableis effectively prevented from being damaged by abrading and bending, and the effective data transmission between the throw-in type underwater monitoring equipment wireless data transmission mechanismand the sensor probe is guaranteed.

Description

technical field [0001] The invention relates to the field of supporting facilities for underground well detection equipment, in particular to an input-type groundwater monitoring equipment cable locking device. Background technique [0002] The input groundwater monitoring equipment is generally composed of three parts, the sensor probe used below the water surface, the signal transmission cable, and the wireless data transmission mechanism on the water surface. The signal transmission cable is the link connecting the wireless data transmission mechanism and the sensor probe. When the signal transmission cable is working, it transmits various data detected by the sensor probe to the wireless data transmission mechanism, and the wireless data transmission mechanism transmits various data to the background management party. When installing the submersible groundwater monitoring equipment, the sensor probe needs to be lowered below the water surface. After the installer determi...

Problems solved by technology

[0004] In order to overcome the disadvantages of existing underground wells with more than length cable fixing, the present invention provides a hook that can replace the existing wellhead protection device, and after fixing the cable between the sensor probe and the wireless data transmission mechanism, the cable The cable will not be bent, which effectively prevents the insulation surface from being damaged due to cable bending and contact wear between the cable and the metal wire rope, and ensures the effective transmission of data by the sensor probe.
