Description

Technical Field

[0001] The utility model relates to the technical field of temperature alarms, in particular to an explosion-proof temperature alarm. Background Art

[0002] A temperature alarm is an instrument that uses a temperature sensor to detect the external temperature in real time. When the measured temperature reaches or exceeds the set alarm threshold, an alarm will be given by sound, display or other means. An explosion-proof temperature alarm is a type of temperature alarm that is specially designed for equipment operating in flammable and explosive environments. Explosion-proof temperature alarms are now widely used in the steel, electric power, chemical and other industries. The dust removal equipment in these industries is usually in harsh environments such as high temperature and high pressure, and is prone to failures and accidents.

[0003] At present, when using explosion-proof temperature alarms, there is a lack of structure to buffer the impact of external objects, and there is no function to reinforce the explosion-proof shell, resulting in a poor explosion-proof effect. For this reason, we propose an explosion-proof temperature alarm. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides an explosion-proof temperature alarm, which has a structure for buffering the impact force of foreign objects and has the function of reinforcing the explosion-proof shell, thereby effectively improving the explosion-proof effect.

[0006] A base is provided at the bottom of the temperature alarm, connecting ear plates are connected to both ends of the bottom of the U-shaped reinforcement frame, a hollow cavity is provided between the temperature alarm and the explosion-proof housing, and a spring is embedded in the hollow cavity.

[0007] By adopting the above technical solution, personnel can fasten the U-shaped reinforcement frame to the base by using cross screws, No. 1 bolt holes and No. 2 bolt holes, and then fasten the U-shaped reinforcement frame to the periphery of the explosion-proof shell, so as to limit the position of the explosion-proof shell, thereby further improving the explosion-proof performance of the explosion-proof shell;

[0008] Personnel embed springs inside the hollow cavity between the explosion-proof housing and the temperature alarm and between the bottom of the temperature alarm and the base. The springs can buffer the impact force generated by external objects, thereby reducing the impact of the impact force on the temperature alarm.

[0009] Specifically, a cross screw is provided on the outer side of the connecting ear plate by opening a No. 1 bolt hole, and No. 2 bolt holes corresponding to the No. 1 bolt hole are opened on both sides of the top of the base.

[0011] By adopting the above technical solution, the explosion-proof housing can protect the temperature alarm on one side of the temperature alarm. The personnel can remove the fastening bolts to separate the transparent plate from the explosion-proof housing for easy maintenance.

[0012] Specifically, a sensing probe is provided at the lower end of one side of the temperature alarm by opening a No. 1 wire passing hole.

[0013] Specifically, a second wire passing hole corresponding to the first wire passing hole is opened at the lower end of the bottom of the transparent plate.

[0014] By adopting the above technical solution, the No. 2 wire hole facilitates the contact between the sensor probe and the external air, and the No. 2 wire hole can further improve the stability of the sensor probe.

[0015] Specifically, ventilation holes are evenly arranged on the other side of the explosion-proof housing.

[0016] Beneficial effects of the utility model:

The outer side of the temperature alarm 1 is provided with an explosion-proof housing 2, and the outer side of the explosion-proof housing 2 is provided with a U-shaped reinforcement frame 3;

[0026] A base 4 is provided at the bottom of the temperature alarm 1, connecting ear plates 6 are connected to both ends of the bottom of the U-shaped reinforcement frame 3, a hollow cavity 15 is provided between the temperature alarm 1 and the explosion-proof housing 2, and a spring 5 is embedded in the hollow cavity 15.

[0027] When in use, personnel can use the cross screw 7, the No. 1 bolt hole 9 and the No. 2 bolt hole 11 to fasten the U-shaped reinforcement frame 3 to the base 4, and then fasten the U-shaped reinforcement frame 3 to the periphery of the explosion-proof shell 2, so as to limit the explosion-proof shell 2, and further improve the explosion-proof performance of the explosion-proof shell 2;

[0028] Personnel embed a spring 5 inside the hollow cavity 15 between the explosion-proof housing 2 and the temperature alarm 1 and between the bottom of the temperature alarm 1 and the base 4. The spring 5 can buffer the impact force generated by external objects, thereby reducing the impact of the impact force on the temperature alarm 1.

[0030] When in use, a person can fasten the U-shaped reinforcement frame 3 to the base 4 through the cross screw 7 , the No. 1 bolt hole 9 and the No. 2 bolt hole 11 .

[0031] For example, Figure 1 As shown, a transparent plate 8 is installed on one side of the explosion-proof housing 2 through fastening bolts 10, and fastening bolts 10 are provided on the four sides of the outer side of the transparent plate 8 through No. 3 bolt holes 13, and No. 4 bolt holes 14 corresponding to the No. 3 bolt holes 13 are provided on the four sides of one side of the explosion-proof housing 2.

[0032] When in use, the explosion-proof housing 2 can protect the temperature alarm 1 on one side of the temperature alarm 1. When a person removes the fastening bolts 10, the transparent plate 8 can be separated from the explosion-proof housing 2 for easy maintenance.
