Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facilities, in particular to a temperature sensor for a fire-fighting system. Background Art

[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. It utilizes the characteristic that the resistance value of NTC changes with temperature to convert a non-electrical physical quantity into an electrical quantity, thereby enabling precise temperature measurement and automatic control of a semiconductor device.

[0003] Currently, when a temperature sensor for a fire-fighting system is in use, in order to ensure the normal operation of the temperature sensor, it is necessary to detect the temperature sensor at regular intervals. Since most temperature sensors are directly fixed to the ceiling by bolts, when maintenance personnel repair multiple temperature sensors, they need to continuously turn the bolts, making the disassembly and installation of the temperature sensor inconvenient. At the same time, although some temperature sensors are fixed to the ceiling by a clamping method, when disassembling the temperature sensor for maintenance, one hand needs to hold the temperature sensor, and the other hand needs to release the clamping connection to prevent the temperature sensor from falling off the ceiling directly due to the release of the clamping connection and causing damage, resulting in poor practicability.

[0004] Therefore, it is necessary to provide a temperature sensor for a fire-fighting system to solve the above technical problems. Content of the Utility Model

Specific implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-5, a temperature sensor for a fire protection system provided by the utility model: including a fixed seat 1, an installation groove 2 is opened at the bottom of the fixed seat 1, a temperature sensor body 3 is arranged inside the installation groove 2, the installation groove 2 is adapted to the temperature sensor body 3, a buffer assembly is arranged on the temperature sensor body 3, a square groove 4 and an annular groove 5 are opened inside the installation groove 2, a permanent magnet 6 is fixedly connected inside the square groove 4, two L-shaped blocks 7 are fixedly connected inside the annular groove 5, a square groove 8 is opened at the top of the temperature sensor body 3, a permanent magnet 9 is fixedly connected inside the square groove 8, the permanent magnet 6 is magnetically connected to the permanent magnet 9, two L-shaped blocks 10 are arranged on the temperature sensor body 3, and both of the two L-shaped blocks 10 are adapted to the annular groove 5.

[0031] A power connection port 11 is arranged on the fixed seat 1, the other end of the power connection port 11 is fixedly connected with a power cord 12, a charging port 13 is arranged at the top of the temperature sensor body 3, and the charging port 13 is adapted to the power connection port 11.

[0032] Two device grooves 14 are opened at the top of the temperature sensor body 3, springs 15 are arranged inside both of the two device grooves 14, the other ends of both of the two springs 15 are fixedly connected with connecting plates 16, the two device grooves 14 are respectively adapted to the two connecting plates 16, the tops of the two connecting plates 16 are respectively fixedly connected with the bottoms of the two L-shaped blocks 10, the two device grooves 14 are respectively adapted to the two L-shaped blocks 10. Through the arrangement of the device grooves 14, the springs 15 and the connecting plates 16, when the temperature sensor body 3 is overhauled and needs to be reset, after the temperature sensor body 3 is inserted into the installation groove 2, when the L-shaped block 10 after being inserted into the installation groove 2 just abuts against the L-shaped block 7, the spring 15 contracts, driving the connecting plate 16 and the L-shaped block 10 to move towards the inside of the device groove 14, avoiding the L-shaped block 10 being directly damaged due to abutting against the L-shaped block 7. After rotating the temperature sensor body 3, under the action of the elastic force, the spring 15 will eject the L-shaped block 10 out of the device groove 14, and the L-shaped block can extend into the annular groove 5.

[0033] The buffer assembly includes four slots 17, all of the four slots 17 are opened at the top of the temperature sensor body 3, and dampers 18 are fixedly connected inside all of the four slots 17.

[0034] Working principle: When the temperature sensor body 3 needs to be repaired during use, the repairman climbs up and removes the temperature sensor body 3 with the help of a ladder or other climbing tools. The repairman only needs to hold the temperature sensor body 3 and rotate the temperature sensor body 3 to separate the two L-shaped blocks 10 from the two L-shaped blocks 1 7 respectively, and then pull down the temperature sensor body 3 to separate the permanent magnet 1 6 from the permanent magnet 2 9 magnetically, and separate the power port 11 from the charging port 13, so that the temperature sensor body 3 can be taken out of the installation slot 2 after power is turned off, and the removed temperature sensor body 3 can be repaired;

[0035] When the temperature sensor body 3 is overhauled and needs to be reset, the temperature sensor body 3 is inserted into the mounting groove 2 so that the permanent magnet 1 6 and the permanent magnet 2 9 are magnetically attracted to each other. In the process of magnetic adsorption of the permanent magnet 1 6 and the permanent magnet 2 9, the four dampers 18 and the tops of the two L-shaped blocks 2 10 will respectively abut against the inner wall of the mounting groove 2 and the inner wall of the annular groove 5. The four dampers 18 absorb the force generated when the temperature sensor body 3 collides with the fixing seat 1, and the two L-shaped blocks 2 10 are directly installed in the groove 14. Then, the temperature sensor body 3 is rotated and the temperature sensor is pulled down to ensure that the two L-shaped blocks 2 10 are respectively connected to the two L-shaped blocks 1 7, so that the temperature sensor body 3 will not be pulled out of the mounting groove 2. At this time, the charging port 13 will be connected to the power port 11, and the temperature sensor body 3 will be energized, thereby completing the installation of the temperature sensor body 3.
