Temperature-measurement cable protection device for test and control for grain situation

Abstract

The invention discloses a temperature-measurement cable protection device for test and control for grain situation. The device is characterized by comprising a shell, wherein an opening end is formedin the shell and is used for sleeving the end part of an outer sheath of a temperature-measurement cable with the shell; a cable storage space for containing the core wire lead end of the temperature-measurement cable is formed between the shell and the end part of the outer sheath; a wire outlet is formed in the shell, is communicated with the wire storage space and can be penetrated by the corewire lead end; and a seal part is arranged at the wire outlet. The temperature-measurement cable protection device can be used for effectively preventing dust impurities from entering the gap betweena core wire and a core wire sleeve, has a good dust-proof effect, ensures the core wire to enter and exit the core wire sleeve smoothly, so that maintenance and replacement can be performed for a corewire and a temperature sensor conveniently, the core wire lead end of a temperature-measurement cable is prevented from being broken by the impact of grain storage in-out operation, the working reliability of a grain situation test and control system can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of grain condition measurement and control, in particular to a temperature measuring cable protection device for grain condition measurement and control. Background technique [0002] The grain situation measurement and control system sets a number of temperature measuring cables along the vertical direction according to standard intervals in the granary, and the number of temperature measuring cables required for different volumes of granaries is different. The temperature measuring cable is generally composed of a temperature sensor, a core wire, a tensile steel wire and an outer sheath. There are several temperature sensors at intervals on the core wire. The core wire is wrapped by the outer sheath, and the outer sheath is provided with a The two ends of the temperature measuring cable are connected to the top and bottom of the granary through tensile steel wires to ensure the stability of the temperature...
