Description

Technical Field

[0001] The utility model relates to the technical field of safety barriers, in particular to a thermocouple input safety barrier. Background Art

[0002] Safety barriers, also known as safety retainers, can transmit electrical signals bidirectionally between the safe area and the dangerous area, and can limit the energy transfer from the safe area to the dangerous area caused by faults. Generally, safety barriers are of Zener type and isolation type. Intrinsically safe safety barriers are used in the design of intrinsically safe explosion-proof systems. They are devices installed in safe places and contain intrinsically safe circuits and non-intrinsically safe circuits. The energy sent to the intrinsically safe circuit on site is limited by current limiting and voltage limiting circuits in the circuit, thereby preventing the dangerous energy of the non-intrinsically safe circuit from entering the intrinsically safe circuit. It is called associated equipment in the intrinsically safe explosion-proof system and is an important part of the intrinsically safe system. Associated equipment of the intrinsically safe explosion-proof system refers to electrical equipment installed in a safe place and connected between intrinsically safe electrical equipment and non-intrinsically safe electrical equipment.

[0003] For example, the Chinese patent with the publication number CN113113901A proposes an isolated safety barrier, which includes a safety barrier body, a power supply part, a functional circuit part and a control part. The functional circuit part is arranged inside the safety barrier body, and the functional circuit part includes at least two groups of circuit units with different functions and capable of working independently. Each circuit unit includes an inlet end and an outlet end. The safety barrier body is provided with an interface part, and the interface part includes an access port and an output port. The inlet end is connected to the inner side of the access port, and the outlet end is connected to the inner side of the output port. The control part is used to switch the connection and disconnection between different circuit units and the interface part. A variety of functional isolation safety barriers are integrated in the same device, and a specific functional circuit can be controlled to work, so that signal adaptation can be achieved, and it can be used for a variety of signal types, increasing the functional diversity of the same safety barrier and saving operation time. However, in the actual application of this solution, when the number of safety barriers installed on the mounting bar is relatively large, if one of the safety barriers is damaged, it is necessary to remove the other safety barriers before it can be removed, which can easily prolong the time required for the staff to replace the safety barriers. In order to solve the above problems, we propose a thermocouple input safety barrier. Utility Model Content

[0016] Preferably, two threaded holes are provided on one side of the sliding block, and bolts are connected to the internal threads of the threaded holes.

[0017] By adopting the above technical solution and setting a sliding block, when the sliding block moves inside the sliding groove, it is convenient to adjust the position of the mounting block on one side of the safety barrier body later, so as to adjust the distance between the second clamping block and the first clamping block, so as to facilitate fixing the safety barrier body on mounting strips of different sizes later.
