Description
Technical Field
The invention relates to the technical field of temperature monitoring, in particular to an overtemperature warning box.
Background
In the actual operation of the power line, the resistance of the connection part of the splicing fitting is easy to increase due to the loosening of the bolt, the dirt of the contact surface, the infirm lead sealing of the tail pipe of the cable, the electrochemical corrosion of copper and aluminum and the like, and under the conditions of large load, large current and the like, the local overhigh temperature is easy to cause various faults. The failure caused by the splicing fitting is usually unrecoverable, a large amount of manpower and material resources are needed to be invested for rush repair, and the power grid has great influence on the society.
Therefore, it is necessary to perform regular maintenance and monitoring on the splicing fitting of the power line, and the current main method is to perform regular infrared temperature measurement on the splicing fitting to search for heating faults. The operation personnel regularly carry out temperature measurement detection on the line according to the operation and maintenance strategy, and particularly carry out temperature measurement at night when the line load is highly innovative. However, infrared temperature measurement is greatly affected by the environment, cannot be performed in severe environments such as dust, smoke, steam and the like, and has low measurement accuracy on the surface of smooth metal.
Disclosure of Invention
The invention provides an overtemperature warning box, which aims to overcome the technical defects that the prior art is easily influenced by the environment and has low measurement precision of continuous hardware during monitoring the continuous hardware.
In order to realize the purpose, the technical scheme is as follows:
an overtemperature warning box comprises a box body, a groove formed in the box body, a cover plate arranged on the box body and used for sealing or opening the groove, a temperature sensing glass ball arranged in the box body and fixedly connected with the box body, a pressure lever arranged in the groove, a torsion spring arranged in the groove and a prompting belt arranged in the groove; the temperature sensing glass ball is connected with the cover plate through the pressure rod, the first end of the torsion spring is connected with the inner wall of the groove, the second end of the torsion spring is connected with the cover plate, and one end of the prompt belt is connected with the inner wall of the groove.
When the overtemperature warning box provided by the invention is used, the box body is firstly connected with an object needing overtemperature warning, such as a splicing fitting, so that the box body and the object are tightly attached. Under normal conditions, the torsion spring gives the cover plate a downward acting force through the second end, but because the cover plate is connected with the temperature sensing glass ball through the pressure rod, the temperature sensing glass ball gives the cover plate an upward acting force so that the cover plate is maintained in a balanced state, and the groove is sealed. In the using process, the temperature of the object is transmitted to the temperature sensing glass ball through the box body, and when the transmitted temperature is lower than the warning temperature of the temperature sensing glass ball, the warning box is maintained in a normal state. When the transmitted temperature is higher than the warning temperature of the temperature sensing glass ball, the temperature sensing glass ball is broken, the balance state of the cover plate is broken, the torsion spring applies downward acting force to the cover plate, the groove is opened, and the prompt belt arranged in the groove floats out of the groove. In practical application, a technician can determine whether the object exceeds the early warning temperature by observing whether the prompt tape is drifted out of the groove.
Compared with the prior art, the invention has the beneficial effects that:
the warning box provided by the invention senses the temperature of an object through the temperature sensing glass ball, when the temperature of the object is higher than the early warning temperature, the temperature sensing glass ball is broken and damaged, and the warning tape is controlled to float out through the corresponding mechanical structure, so that the operator can be prompted that the temperature of the object exceeds the early warning temperature. The warning device provided by the invention has the advantages of no environmental influence and high measurement precision.

Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the patent;
the invention is further illustrated below with reference to the figures and examples.
Example 1
As shown in fig. 1 and 2, the overtemperature warning box includes a box body 1, a groove 2 formed on the box body 1, a cover plate 3 arranged on the box body 1 and used for sealing or opening the groove 2, a temperature sensing glass ball 4 arranged in the box body 1 and connected with the box body 1, a pressure lever 5 arranged in the groove 2, a torsion spring 6 arranged in the groove 2 and a prompt belt 7 arranged in the groove 2; the temperature sensing glass ball 4 is connected with the cover plate 3 through the pressure lever 5, the first end of the torsion spring 6 is connected with the inner wall of the groove 2, the second end of the torsion spring 6 is connected with the cover plate 3, and one end of the prompting belt 7 is connected with the inner wall of the groove 2; one side of recess 2 is provided with the opening, and the opening coats and is stamped entrance guard's board 9, entrance guard's board 9 passes through the screw 10 to be fixed on box body 1. The connecting rod 11 is arranged in the groove 2 of the box body 1, two ends of the connecting rod 11 are respectively connected with the inner wall of the groove 2, the cover plate 3 is hinged to the connecting rod 11, and the torsion spring 6 is sleeved on the connecting rod 11. The temperature sensing glass ball 4 is arranged in the through hole 12, the temperature sensing glass ball 4 is connected with the pressure lever 5 through a through hole, and the left side and the right side of the through hole 12 are sealed through screws 10.
