Technical Field

[0001] This utility model belongs to the field of dustproof sealing technology for infrared volatile organic gas imager lenses, specifically relating to a dustproof sealing structure for infrared volatile organic gas imager lenses. Background Technology

[0002] Infrared volatile organic gas imager (VOCs imager or OGI device) is a detection device based on infrared thermal imaging technology. It is specifically designed to visualize the leakage of volatile organic compounds in real time, enabling rapid location of the leakage source and quantitative assessment of the leakage intensity. To prevent dust from adhering to the lens of the imager, it is usually placed in a sealed enclosure for use.

[0003] The aforementioned devices lack a structure for quick sealing and fixing of the sealing cover during use. As a result, most existing sealing covers are fixed by snap-fit ​​or screws. Snap-fit ​​connections are difficult to guarantee a sealing effect, while screw connections require tools for disassembly and assembly. Furthermore, repeated disassembly and assembly of the sealing cover can easily cause the screw holes to slip during internal imaging and maintenance, reducing the sealing effect. Based on the shortcomings of existing technology, this utility model designs a dustproof sealing structure for the lens of an infrared volatile organic gas imager. Utility Model Content

[0029] The sealing strip 103 is movably engaged inside the sealing groove 404, and the limiting ring 108 is slidably connected inside the connecting cylinder 106.

[0030] The cleaning mechanism 3 includes a scraper 301, a motor 302 and a limiting plate 303. The scraper 301 is rotatably connected to one side of the dust cover 1. The motor 302 is located inside the dust cover 1. A limiting plate 303 is provided on one side of the motor 302.

[0031] The scraper 301 is rotatably connected to one side of the glass plate 105, and the limiting piece 303 is disposed on one side of the scraper 301.

[0032] Further explanation is needed: A connecting rod 101 is provided on one side of the dust cover 1, which is connected to the limiting cylinder 204 on one side of the support rod 2, so that the dust cover 1 can be rotated and adjusted on one side of the support rod 2. A rotating rod 201 is provided at the bottom of the support rod 2, which rotates inside the base 202, so that the support rod 2 can drive the dust cover 1 to rotate and adjust when the base 202 is installed and fixed through the mounting hole 203.

A dustproof mechanism 4 is provided on the top of the dust cover 1, which facilitates dustproof sealing of the top of the dust cover 1.

[0033] Example 2

[0034] Please see Figure 3-6 The present invention provides the following technical solution:

[0035] The dustproof mechanism 4 includes a dustproof cover 401, a connecting hole 402, a magnetic block 403, a sealing groove 404, and a magnetic strip 405. The dustproof cover 401 is located on the top of the dustproof cover 1. The bottom of the dustproof cover 401 has a connecting hole 402. The magnetic block 403 is fixedly connected inside the connecting hole 402. The bottom of the dustproof cover 401 has a sealing groove 404. The bottom of the dustproof cover 401 is fixedly connected to the magnetic strip 405.

[0036] The connecting hole 402 is located on the top of the connecting cylinder 106, and the magnetic block 2 403 is located on the top of the magnetic block 107.

[0037] Magnetic strip 2 405 is located on top of magnetic strip 1 104, and dust cover 401 is located on top of lens body 102.

[0038] Further explanation is needed: After the lens body 102 inside the dust cover 1 is installed, place the dust cover 401 on top of the dust cover 1, and align the sealing groove 404 and magnetic strip 2 405 at the bottom of the dust cover 401 with the sealing strip 103 and magnetic strip 104 on the dust cover 1. After alignment, directly cover the top of the dust cover 1 with the dust cover 401, so that the sealing strip 103 is inserted into the sealing groove 404. At the same time, the magnetic strip 2 405 and the magnetic strip 104 are magnetically connected to complete the sealing connection. After the dust cover 401 is fully aligned and covered on the dust cover 1, the magnetic block 2 403 is above the magnetic block 107. The magnetic block 107 moves upward and inserts into the connection hole 402 due to the attraction of like poles, thus locking the sliding between the dust cover 1 and the dust cover 401.

[0039] Working principle: When a dustproof sealing structure for an infrared volatile organic gas imager lens is used, a connecting rod 101 is first set on one side of the dust cover 1. The connecting rod 101 is connected to the limiting cylinder 204 on one side of the support rod 2, so that the dust cover 1 can be rotated and adjusted on one side of the support rod 2. A rotating rod 201 is set at the bottom of the support rod 2. The rotating rod 201 rotates inside the base 202, so that the support rod 2 can drive the dust cover 1 to rotate and adjust when the base 202 is installed and fixed through the mounting hole 203. A cleaning mechanism 3 is set on one side of the dust cover 1. A scraper 301 is set to facilitate cleaning of the glass plate 105. A dustproof mechanism 4 is set on the top of the dust cover 1. The dustproof mechanism 4 facilitates dustproof sealing of the top of the dust cover 1.

[0040] When it is necessary to quickly seal the dust cover 401 onto the dust cover 1, first, after the lens body 102 inside the dust cover 1 is installed, place the dust cover 401 on top of the dust cover 1, and align the sealing groove 404 and magnetic strip 2 405 at the bottom of the dust cover 401 with the sealing strip 103 and magnetic strip 104 on the dust cover 1. After alignment, directly cover the top of the dust cover 1 with the dust cover 401, so that the sealing strip 103 snaps into the seal. Simultaneously within the groove 404, magnetic strip 2 405 and magnetic strip 1 104 are magnetically connected to complete the sealing connection. After the dust cover 401 is fully aligned and closed on the dust cover 1, magnetic block 2 403 is positioned above magnetic block 1 107. Due to the attraction of like poles, magnetic block 1 107 moves upward and inserts into the connection hole 402, locking the sliding between the dust cover 1 and the dust cover 401. This device facilitates the quick sealing and closing of the dust cover 401 onto the dust cover 1.
