Description

Technical Field

[0001] The utility model relates to the technical field of temperature detection devices, in particular to an infrared thermal imaging power supply circuit temperature anomaly detection device. Background Technique

[0002] During the operation of an infrared thermal imaging device, if there is a temperature anomaly in the power supply circuit, it may cause serious damage to the device. For example, when there is local overheating in the power supply circuit, it may cause the wire insulation layer to age and accelerate, or even burn out, triggering a short-circuit fault, which in turn affects the normal operation of the entire thermal imaging system. The temperature anomaly detection device can monitor the temperature of the power supply circuit in real time. Once it detects that the temperature exceeds the normal range, it will promptly issue an alarm so that corresponding measures can be taken, such as cutting off the power supply for maintenance, etc., thus ensuring the safe operation of the device.

[0003] Under the existing technology, for example, a Chinese patent with the publication number CN214544899U discloses a circuit board device capable of temperature detection and alarm, which relates to the technical field of circuit boards, including a base, on the outer surface of which a circuit board housing is fixedly connected, on the outer surface of which an infrared detector is fixedly connected, and on the outer surface of which a fan machine is fixedly connected.

[0004] Although the above device can detect power supply anomalies, in actual use, when most circuit temperature anomalies are caused by short-circuit problems, fan cooling cannot fundamentally solve the problem. The short-circuit fault may continuously generate a large amount of heat. The fan can only play a certain role in heat dissipation, but cannot eliminate the short-circuit fault itself. In this case, fan cooling may only temporarily relieve the temperature rise, but cannot prevent the temperature from continuing to rise, and may even not be able to effectively reduce the temperature to a safe range. Therefore, we propose an infrared thermal imaging power supply circuit temperature anomaly detection device to solve the above problems. Content of the Utility Model

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by the utility model is as follows:

[0007] An infrared thermal imaging power supply circuit temperature anomaly detection device, including an assembly tube, wherein a trigger assembly for disconnecting the circuit is arranged inside the assembly tube, and a detection assembly is installed on one side of the inner wall of the assembly tube. The trigger assembly includes a plurality of guiding grooves, which are opened on the inner wall of the assembly tube. One side of the inner wall of the guiding groove is fixedly connected with a fixed cylinder, and a telescopic spring is arranged inside the fixed cylinder. One end of the telescopic spring away from the fixed cylinder is provided with a guiding seat. One end of the guiding seat close to the center of the assembly tube is fixedly connected with a fixed ring, and a spiral wire is installed on the inner wall of the fixed ring. The spiral wire is in the circuit of the infrared thermal imaging power supply. One end of the spiral wire away from the fixed ring is fixedly connected with a moving contact, a pole column is sleeved inside the spiral wire, and a magnetic seat is arranged at one end of the spiral wire away from the moving contact.

[0008] Preferably, both ends of the assembly tube are fixedly connected with connecting heads, and external threads are opened on the surfaces of the connecting heads.

[0009] Preferably, the detection assembly includes a temperature sensor, and a fixed seat is fixedly connected to one side of the outer surface of the assembly tube.

[0010] Preferably, the plurality of guiding grooves are evenly distributed around the axis of the assembly tube, the guiding seat is placed inside the guiding groove, and the guiding seat is slidably connected with the groove wall of the guiding groove.

[0011] Preferably, a connecting groove is opened on one side of the guiding seat close to the telescopic spring, and one end of the telescopic spring away from the fixed cylinder contacts the bottom of the inner cavity of the connecting groove.

[0012] Preferably, one end of the pole column is fixedly connected with an insulating part, and one end of the insulating part away from the pole column is fixedly connected with the spiral wire.

[0013] Preferably, a buzzer alarm is installed on one side of the fixed seat, and the output end of the temperature sensor is electrically connected to the input end of the control unit of the buzzer alarm.

[0014] Preferably, a connecting seat is fixedly connected to one side of the magnetic seat, and one end of the connecting seat away from the magnetic seat is fixedly connected with the inner wall of the assembly tube.

[0015] By adopting the above technical solutions, the beneficial effects obtained by the present utility model are as follows:

[0016] In the present utility model, the temperature sensor on the inner wall of the assembly tube can monitor the temperature of the infrared thermal imaging power supply circuit in real time and accurately. Once temperature anomaly is found, it can quickly send a signal to the control unit of the buzzer alarm, trigger the alarm mechanism, remind the staff to take measures in time, and avoid the expansion of the accident;

[0017] The structural designs of components such as the spiral wire, pole column, and magnetic base in the triggering component are ingenious. When an abnormality occurs in the circuit, leading to a temperature rise and failure to disconnect in a timely manner, the current in the spiral wire increases, and the magnetic force formed in cooperation with the pole column becomes larger. The pole column is attracted and moves closer to the magnetic base, driving the moving contact to disconnect the circuit, thus realizing the function of automatically protecting the safety of equipment and personnel. The design of the fixed cylinder and telescopic spring in the guiding groove can not only keep the position of the guiding seat stable under normal circumstances but also play a buffering role when the triggering component acts, avoiding too violent a collision between the pole column and the magnetic base.

[0018] Timely detection and handling of abnormal temperature conditions avoid damage to equipment in the power supply circuit caused by high temperature, extend the service life of the equipment, reduce the costs of equipment maintenance and replacement, and the application of this device will greatly improve the safety of the infrared thermal imaging power supply circuit. Through the functions of real-time temperature monitoring and automatic disconnection of abnormal circuits, accidents such as fires and equipment damage caused by excessive temperature can be effectively prevented, protecting the lives and property safety of personnel.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0026] Embodiment: As Figures 1 - 5 shown, the present utility model provides an infrared thermal imaging power supply circuit temperature anomaly detection device, including an assembly pipe 1. Both ends of the assembly pipe 1 are fixedly connected with connection heads 101. External threads 102 are provided on the surfaces of the connection heads 101. A detection component 2 is installed on one side of the inner wall of the assembly pipe 1. The detection component 2 includes a temperature sensor 201. A fixed seat 203 is fixedly connected to one side of the outer surface of the assembly pipe 1. A buzzer alarm 202 is installed on one side of the fixed seat 203. The output end of the temperature sensor 201 is electrically connected to the input end of the control unit of the buzzer alarm 202. A trigger component 3 for disconnecting the circuit is provided inside the assembly pipe 1. The temperature sensor 201 on one side of the inner wall of the assembly pipe 1 monitors the temperature of the power supply circuit in real time. When the temperature is normal, the temperature sensor 201 outputs a corresponding electrical signal. If the temperature sensor 201 detects an abnormal temperature, its output end will send a signal to the control unit of the buzzer alarm 202, triggering the buzzer alarm 202 to sound an alarm to remind the staff. Through the temperature sensor 201, the temperature of the infrared thermal imaging power supply circuit can be monitored in real time, and abnormal temperature conditions can be discovered in a timely manner. Once an abnormal temperature is detected, the buzzer alarm 202 can quickly sound an alarm to remind the staff to take measures to avoid further expansion of the accident.

[0027] Further, the trigger assembly 3 includes a plurality of guiding grooves 301 which are formed on the inner wall of the assembly pipe 1. The plurality of guiding grooves 301 are evenly distributed around the axis of the assembly pipe 1. One side of the inner wall of the guiding groove 301 is fixedly connected with a fixing cylinder 302. A telescopic spring 303 is arranged inside the fixing cylinder 302. One end of the telescopic spring 303 away from the fixing cylinder 302 is provided with a guiding seat 304. The guiding seat 304 is placed in the guiding groove 301 and is slidably connected with the wall of the guiding groove 301. A connecting groove 305 is formed on one side of the guiding seat 304 close to the telescopic spring 303. The end of the telescopic spring 303 away from the fixing cylinder 302 contacts the bottom of the inner cavity of the connecting groove 305. One end of the guiding seat 304 close to the center of the assembly pipe 1 is fixedly connected with a fixing ring 306. A spiral wire 307 is installed on the inner wall of the fixing ring 306. The spiral wire 307 is in the circuit for supplying power to the infrared thermal imaging device. One end of the spiral wire 307 away from the fixing ring 306 is fixedly connected with a moving contact 308. A pole column 309 is sleeved inside the spiral wire 307. One end of the pole column 309 is fixedly connected with an insulating part 310. The end of the insulating part 310 away from the pole column 309 is fixedly connected with the spiral wire 307. One end of the spiral wire 307 away from the moving contact 308 is provided with a magnetic seat 311. One side of the magnetic seat 311 is fixedly connected with a connecting seat 312. The end of the connecting seat 312 away from the magnetic seat 311 is fixedly connected with the inner wall of the assembly pipe 1. When the circuit has an abnormality resulting in a temperature rise, if the circuit is not disconnected in time, the current in the spiral wire 307 will increase. According to the electromagnetic principle, the increase in current makes the magnetic force formed by the cooperation of the spiral wire 307 and the pole column 309 become larger. At this time, the pole column 309 will move closer to the magnetic seat 311 and be adsorbed, driving the moving contact 308 to disconnect, so that the circuit is disconnected. The trigger assembly 3 can automatically disconnect the circuit when the circuit has an abnormality, protecting the safety of the equipment and personnel. Especially when the current in the spiral wire 307 increases, the electromagnetic principle is utilized to make the pole column 309 adsorbed onto the magnetic seat 311, quickly disconnecting the moving contact 308 to achieve reliable circuit protection.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
