Description

Technical Field

[0001] This utility model relates to the field of camera technology, specifically to an explosion-proof tri-lens infrared thermal imaging camera. Background Technology

[0002] A tri-lens infrared thermal imaging camera is an advanced monitoring device that combines infrared thermal imaging technology with traditional video surveillance technology. It can provide more comprehensive and accurate monitoring results. This type of camera is usually equipped with three different lenses, which are used to capture infrared thermal images, visible light images, and other specific function images, thereby realizing multi-dimensional data acquisition and analysis.

[0003] Tri-lens infrared thermal imaging cameras have a wide range of applications, covering multiple fields such as military, industry, security, transportation, and medical. The wide range of applications also places higher demands on the quality of the cameras.

[0004] An existing tri-lens infrared thermal imaging camera lacks fire prevention and emergency measures during use. When used in chemical plants or in environments where open flames are prohibited, if a short circuit occurs due to a circuit problem and sparks ignite the device, the existing camera cannot extinguish the fire immediately, causing the fire to spread and resulting in serious consequences.

[0005] Therefore, an explosion-proof tri-lens infrared thermal imaging camera is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: A rotating base 4 is installed on the top of the mounting plate 1. A support component 5 is fixed on the top of the rotating base 4. A metal protective shell 6 is installed on the top of the support component 5. A sealing cover 8 is fixed to the top of the metal protective shell 6 by bolts. A hanging rope 9 is installed at the top inside the sealing cover 8. A suspended dry powder fire extinguisher 10 is connected to the bottom of the hanging rope 9. A heat-sensing glass nozzle 7 is installed at the bottom of the suspended dry powder fire extinguisher 10. The heat-sensing glass nozzle 7 is used in conjunction with the suspended dry powder fire extinguisher 10. A camera body 11 is fixed to the bottom inside the metal protective shell 6 by bolts.

[0023] Specifically, such as Figure 1 and Figure 2As shown, the camera body 11 is bolted to the bottom of the metal protective housing 6, and an explosion-proof transparent glass is installed on one side of the metal protective housing 6. When in operation, the camera body 11 can monitor the external environment through one side of the metal protective housing 6. A sealing cover 8 is bolted to the top of the metal protective housing 6, and a suspended dry powder fire extinguisher 10 is installed inside the sealing cover 8 via a hanging rope 9. A heat-sensitive glass nozzle 7 is installed at the bottom of the suspended dry powder fire extinguisher 10. Since the heat-sensitive glass nozzle 7 and the suspended dry powder fire extinguisher 10 work together, when the camera body 11 spontaneously combusts and produces an open flame during use, the heat-sensitive glass nozzle 7 will change its internal structure upon heating, causing the extinguishing material stored inside the suspended dry powder fire extinguisher 10 to pour out, thereby extinguishing the open flame generated by the camera body 11. The fire can be extinguished. Meanwhile, since the camera body 11 is installed inside the metal protective housing 6, and the top of the metal protective housing 6 is fitted with a sealing cover 8, when the camera body 11 spontaneously combusts, the metal protective housing 6 and the sealing cover 8 prevent the flame from leaking out, thus protecting the external environment and preventing major accidents. Because the suspended dry powder fire extinguisher 10 is suspended above the camera body 11 by a hanging rope 9, even when the installation angle of the metal protective housing 6 changes, the suspended dry powder fire extinguisher 10 will always remain directly above the camera body 11 due to its own weight, thereby improving extinguishing efficiency. This device can improve safety in scenarios where open flames are strictly prohibited, providing protection and isolation from the surrounding environment. In case of emergencies, it allows for immediate emergency response, reducing losses.

[0024] Example 2: A first motor 12 is bolted to the top of the mounting plate 1, and the output end of the first motor 12 is fixedly connected to the bottom end of the rotating base 4. Four fixing holes 2 are provided inside the mounting plate 1, located at the four corners of the mounting plate 1. The support assembly 5 includes a base plate 506, the bottom end of which is fixedly connected to the top of the rotating base 4. A support slide rod 507 is welded to each side of the bottom of the base plate 506. A ring-shaped groove 13 is provided on the top of the base 3, and the bottom ends of the two support slide rods 507 are slidably installed inside the groove 13. A support side plate 502 is welded to each side of the top of the base plate 506, and a drive shaft 505 is installed between the two support side plates 502 via a rotating shaft. A second motor 501 is bolted to one side of the support side plate 502. The output end of 1 passes through the inside of the support side plate 502 and is fixedly connected to one end of the drive shaft 505. A bracket 504 is fixedly sleeved on the outer side of both ends of the drive shaft 505, and a limiting plate 503 is welded to the top of each of the two brackets 504. The limiting plate 503 is fixedly connected to one side of the camera body 11 by bolts. The camera body 11 includes a camera housing 1101, and a main board 1102 is installed inside the camera housing 1101 by screws. The top of the main board 1102 is provided with an explosion-proof seal 1103. A visible light camera 1105 is installed at one end of the camera housing 1101, and an infrared thermal imaging camera 1104 is installed on each side of the visible light camera 1105. One side of the infrared thermal imaging camera 1104 and the visible light camera 1105 are electrically connected to the main board 1102 through an output line 1106.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rotation of the output end of the first motor 12 can drive the base plate 506 to rotate. When the base plate 506 rotates, the bottom ends of the support slide rods 507 fixed on both sides of the bottom of the base plate 506 will slide inside the slide groove 13, thereby ensuring the stability and support strength of the base plate 506 during rotation. The rotation of the base plate 506 can simultaneously drive the metal protective shell 6 and the camera body 11 to rotate. The rotation of the output end of the second motor 501 can drive the drive shaft 505 to rotate between the two support side plates 502. The rotation of the drive shaft 505 can drive the two brackets 504 to rotate with the drive shaft 505, and simultaneously drive... The moving metal protective shell 6 and the camera body 11 deflect at an angle, thereby flexibly adjusting the monitoring angle of the camera body 11 to the outside world. Infrared thermal imaging camera 1104 and visible light camera 1105 can perform infrared imaging of the outside world, and then transmit the signal to the motherboard 1102 for calculation and analysis through the output line 1106. Since the top of the motherboard 1102 is equipped with an explosion-proof seal 1103, the motherboard 1102 can be further explosion-proofed by the explosion-proof seal 1103, completely sealing the sparks or hot parts that may ignite the explosive mixture, so that it cannot ignite the dust layer or explosive environment under operating or installation conditions.

[0026] Working principle: During installation, the sealing cover 8 is removed, and then the camera body 11 is installed inside the metal protective housing 6. The suspended dry powder fire extinguisher 10 is then connected to the bottom end of the hanging rope 9. The sealing cover 8 is then fixed to the top of the metal protective housing 6 with bolts. The entire device is then installed in the designated position through the fixing holes 2 inside the mounting plate 1. When the camera body 11 spontaneously combusts and produces an open flame during use, the heat-sensitive glass nozzle 7 will change its internal structure upon heating, causing the extinguishing material stored inside the suspended dry powder fire extinguisher 10 to pour out, thereby extinguishing the open flame generated by the camera body 11. Simultaneously, because the camera body 11 is installed inside the metal protective housing 6, and the top of the metal protective housing 6 is fitted with the sealing cover 8, when the camera body 11 spontaneously combusts, the metal protective housing 6 and the sealing cover 8 prevent the open flame from leaking out, thus protecting the external environment and preventing major accidents.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
