Description

Technical Field

[0001] The utility model relates to the technical field of detection instruments, in particular to a detection instrument with a protection structure. Background Art

[0002] A thermal power plant, also known as a coal-fired power plant, is a factory that uses combustibles such as coal as fuel to produce electricity. The coal-fired boiler is a very important part of the equipment in a thermal power plant. In order to ensure the stability of the coal-fired boiler during operation, it is necessary to detect the temperature of the coal-fired boiler to prevent the temperature of the coal-fired boiler from exceeding the standard, so as to facilitate people to control it and make the coal-fired boiler more accurate and reliable. The detection instrument is a very common temperature detection equipment in a thermal power plant. It can effectively provide people with temperature data of the coal-fired boiler, and the detection instrument protects its internal parts through the outer casing when in use.

[0003] During the operation of the coal-fired boiler in a thermal power plant, in order to ensure the stability of the coal-fired boiler during operation and facilitate people to control it, it is necessary to use a detection instrument to detect the temperature of the coal-fired boiler. First, pull the wire to connect the temperature detection head with the device to be tested. The detection instrument displays the detected data through the display screen, so that people can know whether the temperature of the coal-fired boiler exceeds the standard. However, when people install the detection instrument, most of them first connect the detection instrument with the fixing seat, and then install the fixing seat on the device to be tested with screws, and then connect the detection instrument to the device to be tested. However, after people connect the detection instrument with the fixing seat, they also need to manually rotate the bolts to drive the limit plate to move until the limit plate is connected to the outer wall of the detection instrument, and then limit and fix the detection instrument to prevent the detection instrument from moving. This method of limiting the detection instrument is relatively cumbersome, and workers need to manually fix the detection instrument every time, which is not convenient enough. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: when the detection instrument with a protective structure is in use, the detection instruments of different volumes are fixed by a clamping mechanism, and people do not need to manually turn the bolts to drive the limit plate, so the detection instrument can be automatically limited and fixed, saving time and physical effort, thereby facilitating the limit and fixation of the detection instrument, and the temperature detection head can be quickly replaced through the connecting mechanism without cutting the detection wire, which is convenient for people to replace the temperature detection head, thereby facilitating the rapid replacement of the temperature detection head when the detection instrument with a protective structure is in use.

[0016] 1. During the operation of the coal-fired boiler in the thermal power plant, in order to ensure the stability of the coal-fired boiler during operation and facilitate people to control it, it is necessary to install a detection instrument to detect the temperature of the coal-fired boiler. First, the detection instrument housing is docked with the guide rod to cause it to move downward, and then the guide rod moves downward to drive the connecting rod to move downward. At this time, the connecting rod moves along the guide cavity to squeeze the transmission plate, so that the transmission plate rotates along the limit pin, and then the transmission plate rotates to squeeze the limit plate to move until the limit plate docks with the outer wall of the detection instrument housing, thereby fixing the detection instrument. The detection instruments of different volumes can be fixed by moving the limit plate, and people do not need to manually rotate the bolt to drive the limit plate, and the detection instrument can be automatically limited and fixed, saving time and physical strength, so that when the detection instrument with a protective structure is used, it plays a role in facilitating the limit fixing of the detection instrument;

During the operation of the coal-fired boiler in the thermal power plant, in order to ensure the stability of the coal-fired boiler and facilitate people to control it, when the temperature of the coal-fired boiler is detected by the detection instrument, the connector is first connected to the interface, and then the wire connector is connected to the detection connector. Then, the temperature of the coal-fired boiler is detected by the temperature detection head. When the temperature detection head is damaged as the use time increases, the temperature detection head can be quickly replaced by simply connecting the wire connector to the detection connector without cutting the detection wire, which makes it convenient for people to replace the temperature detection head, thereby facilitating the rapid replacement of the temperature detection head when the detection instrument with a protective structure is used.

[0026] During specific implementation, during the operation of the coal-fired boiler in the thermal power plant, in order to ensure the stability of the coal-fired boiler during operation and facilitate people to control it, when it is necessary to install a detection instrument to detect the temperature of the coal-fired boiler, first dock the detection instrument housing 1 with the guide rod 41 on the fixed base 2, and then the guide rod 41 moves downward under the gravity of the detection instrument housing 1, and the guide rod 41 moves downward to drive the connecting rod 44 to move downward, at this time, the connecting rod 44 moves along the guide cavity 45 to squeeze the transmission plate 46, so that the transmission plate 46 rotates along the limit pin 47, and then the transmission plate 46 rotates to squeeze the limit plate 49, and the movement of the limit plate 49 is supported and limited by the limit rod 48 until the limit plate 49 docks with the outer wall of the detection instrument housing 1, and then the detection instrument is fixed by the cooperation of the inner wall of the fixed base 2, and detection instruments of different volumes can be fixed by the movement of the limit plate 49, and then people do not need to manually rotate the bolt to drive the limit plate 49, and the detection instrument can be automatically limited and fixed, saving time and physical strength, so that when the detection instrument with a protective structure is used, it plays a role in facilitating the limit fixing of the detection instrument;
