Abstract
Description
Technical Field
[0001] This utility model relates to the field of detector technology, specifically a heat-resistant infrared detector suitable for high-temperature environments. Background Technology
[0002] Infrared detectors are core devices that achieve non-contact temperature measurement, composition analysis, and condition monitoring by receiving infrared radiation from target objects. They have been widely used in industrial production, fire safety, aerospace, and other fields.
[0003] Infrared detectors can measure objects. However, when used in high-temperature environments, the heat from the existing plastic structures can be quickly transferred to the inside of the detector, causing the internal components to age faster and affecting its lifespan. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] This invention provides a heat-resistant infrared detector suitable for high-temperature environments, aiming to solve the problems mentioned in the background art.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat-resistant infrared detector suitable for high-temperature environments, comprising a base, a detector body installed inside the base, a metal sheet on the outside of the detector body, a heat-resistant layer filled on the outside of the metal sheet, a metal shell installed on the outside of the heat-resistant layer, a temperature sensor installed between the metal sheet and the metal shell, a connecting seat installed on the back of the base, and an adjustment mechanism installed inside the connecting seat.
[0008] As a preferred technical solution of this application, buffer springs are installed at equal intervals at the inner edge of the base, and one end of the buffer spring is connected to the detector body.
[0009] As a preferred technical solution of this application, a buffer block is installed at the central position inside the base.
[0010] As a preferred technical solution of this application, the base is provided with fixing holes at equal intervals at the edge position, and a torsion spring is installed on the front of the connecting seat near the fixing hole, the torsion spring passing through the inside of the fixing hole.
[0011] As a preferred technical solution of this application, a heat dissipation fan is installed inside the connecting seat, and a heat-conducting plate is installed on the outside of the connecting seat.
[0012] As a preferred technical solution of this application, the adjustment mechanism includes a threaded rod assembly disposed on one side inside the connecting seat, and fixing brackets are installed at both ends of the threaded rod assembly.
[0013] As a preferred technical solution of this application, a limit rod is installed inside the fixing frame on the side near the threaded rod assembly.
[0014] (III) Beneficial Effects
[0015] 1. This utility model uses a combination of a metal sheet, a heat-resistant layer, a metal shell, and a temperature sensor. The metal shell directly contacts the external high-temperature environment, blocking most of the radiant and convective heat. At the same time, the high-temperature resistance of the alloy itself resists convective heat erosion. The ceramic fiber cotton heat-resistant layer on the inner side blocks the heat conduction path through its porous structure, reducing the heat permeability. The metal sheet on the outer side of the detector body, through large-area contact, evenly disperses the small amount of heat that permeates, avoiding local hot spots. Meanwhile, the temperature sensor between the metal sheet and the metal shell monitors the temperature value in real time, thereby improving the heat resistance of the device, delaying the aging of its internal components, and thus extending the service life of the infrared detector.
[0016] 2. This utility model uses a temperature sensor, a cooling fan, and a heat-conducting plate in combination. When the temperature sensor detects a high temperature, it sends an electrical signal to start the cooling fan inside the connector. The cooling fan generates a directional airflow, which promotes the dissipation of heat around it. At the same time, the heat-conducting plate, by tightly adhering to the outer wall of the connector, quickly transfers the redundant heat generated by the operation of the device. After the temperature recovers, the fan automatically stops, thereby accelerating the dissipation of heat inside the detector body and improving the heat resistance of the device.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;
[0025] Example:
[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 5 This application provides a heat-resistant infrared detector suitable for high-temperature environments; please refer to it carefully. Figure 1 , Figure 2 and Figure 5 The device includes a base 1, a detector body 2 installed inside the base 1, a metal sheet 201 on the outside of the detector body 2, a heat-resistant layer 202 filled on the outside of the metal sheet 201, a metal shell 203 installed on the outside of the heat-resistant layer 202, a temperature sensor 204 installed between the metal sheet 201 and the metal shell 203, a connecting seat 3 installed on the back of the base 1, and an adjustment mechanism 4 installed inside the connecting seat 3.
[0027] Specifically, the metal shell 203, made of high-temperature resistant alloy, directly contacts the external high-temperature environment, blocking most of the radiant and convective heat. Its inner heat-resistant layer 202 serves as the core heat insulation barrier, using ceramic fiber cotton and a porous structure to block the heat conduction path. The metal sheet 201 on the outside of the detector body 2 disperses heat through large-area contact, evenly conducting the small amount of heat that penetrates into the inner layer to prevent the formation of local hot spots. The temperature sensor 204 between the metal sheet 201 and the metal shell 203 can collect temperature values in real time. The connecting seat 3 and adjustment mechanism 4 on the back of the base 1 can adjust the horizontal position of the detector body 2. In high-temperature industrial scenarios, the adjustment mechanism 4 can accurately align with the target detection area, ensuring that the light path of the infrared optical system is perpendicular to the target surface, reducing signal attenuation caused by angle deviation, and ensuring the accuracy of the detection data.
[0028] Please refer to this carefully. Figure 1 and Figure 4 Buffer springs 102 are installed at equal intervals at the inner edge of the base 1, and one end of the buffer springs 102 is connected to the detector body 2.
[0029] Please refer to this carefully. Figure 4 A buffer block 103 is installed in the center of the base 1.
[0030] Please refer to this carefully. Figure 1 and Figure 2 The base 1 has fixing holes 101 at equal intervals at its edge. A torsion spring 301 is installed on the front of the connecting seat 3 near the fixing hole 101. The torsion spring 301 passes through the interior of the fixing hole 101.
[0031] Specifically, in order to protect the detector body 2, one end of the buffer spring 102 on the inner edge of the base 1 is fixed to the inner wall of the base 1, and the other end is connected to the detector body 2. The buffer spring 102 absorbs radial impact force through elastic deformation, preventing vibration from being directly transmitted to the detector body 2. The buffer block 103 in the center of the base 1 is made of boron rubber to prevent the detector body 2 from colliding with the inner wall of the base 1 and causing damage. During installation, the detector body 2 can be fixedly installed by passing the torsion spring 301 through the inside of the fixing hole 101 and then rotating the torsion spring 301. When the torsion spring 301 is misaligned with the fixing hole 101, the detector body 2 can be fixedly installed. This method also facilitates operation and maintenance by staff later.
[0032] Please refer to this carefully. Figure 1 and Figure 3 A cooling fan 6 is installed inside the connecting seat 3, and a heat-conducting plate 601 is installed on the outside of the connecting seat 3.
[0033] Specifically, in order to improve the heat resistance of the detector body 2, when the temperature sensor 204 detects that the temperature of the metal sheet 201 and the metal shell 203 is high, the temperature sensor 204 sends an electrical signal to start the heat dissipation fan 6 inside the connector 3. When the heat dissipation fan 6 is working, it generates directional airflow, which promotes the dissipation of heat around it. The heat-conducting sheet 601 can accelerate the convection heat exchange with the outside cold air and improve its heat dissipation effect.
[0034] Please refer to this carefully. Figure 1 and Figure 2 The adjusting mechanism 4 includes a threaded rod assembly 401 disposed on one side inside the connecting seat 3, and fixed brackets 402 are installed at both ends of the threaded rod assembly 401.
[0035] Please refer to this carefully. Figure 1 and Figure 2 A limit rod 5 is installed inside the fixing bracket 402 on one side near the threaded rod assembly 401.
[0036] Specifically, in order to adjust the position of the detector body 2, the fixing frame 402 supports the internal threaded rod assembly 401 and the limiting rod 5. The threaded rod assembly 401 consists of a motor and a threaded rod. The output end of the motor is connected to the threaded rod. By rotating the threaded rod assembly 401, the connecting seat 3 can be driven to move the detector body 2, so that the detection position of the detector body 2 can be directly adjusted. The limiting rod 5 can limit the movement of the connecting seat 3.
[0037] Working principle: The operator passes the torsion spring 301 on the front of the connecting seat 3 through the fixing hole 101, and rotates the torsion spring 301 to make it offset from the fixing hole 101. The elastic preload of the torsion spring 301 firmly connects the base 1 and the connecting seat 3. At this time, the metal shell 203 is in direct contact with the external high-temperature environment. The high reflectivity surface blocks most of the radiant heat, and the high temperature resistance of the alloy itself resists convective heat erosion. The ceramic fiber cotton heat-resistant layer 202 on its inner side blocks the heat conduction path through the porous structure, reducing the heat permeability. The metal plate 201 on the outer side of the detector body 2, through large-area contact, evenly disperses the small amount of heat that permeates, avoiding local hot spots. At the same time, the metal plate 201 and the metal shell 2 Temperature sensor 204 between 03 and 03 monitors the temperature value in real time. When the temperature is high, temperature sensor 204 sends an electrical signal to start the heat dissipation fan 6 inside the connecting seat 3. The heat dissipation fan 6 generates directional airflow when it is working, which promotes the dissipation of heat around it. At the same time, the heat conduction plate 601 quickly transfers the redundant heat generated by the operation of the equipment by tightly adhering to the outer wall of the connecting seat 3. After the temperature recovers, the fan automatically stops. The threaded rod assembly 401 supported by the fixing frame 402 starts to work. Through the threaded drive, the connecting seat 3 moves in the horizontal direction, which in turn drives the detector body 2 to adjust the detection position, so that the detector body 2 is accurately aligned with the target area, ensuring that the infrared optical system light path is perpendicular to the target surface for measuring the object.
[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
