Description

Technical Field

[0001] The utility model relates to the field of thermal imaging equipment, in particular to a dual-light gas detection device. Background Art

[0002] The dual-spectrum gas online monitoring PTZ is an advanced monitoring device that combines infrared thermal imaging and high-definition visible light technology, as well as intelligent PTZ control functions, for real-time monitoring of gas leaks. It combines infrared thermal imaging and high-definition visible light imaging technology to clearly capture images of gas leaks under different environmental conditions. The PTZ has high flexibility and stability, and can achieve all-round, multi-angle monitoring to ensure coverage without blind spots. Through infrared thermal imaging technology, it can accurately identify the source of gas leakage and display it in real time in the form of thermal images to help users quickly locate the leak point.

[0003] The detector lens is contaminated by dust, dirt, water droplets or other particles in the environment. These contaminants may adhere to the lens, affecting the image quality, or even blocking the lens, causing the sensor to not work properly. The brush head can prevent these contaminants from directly contacting the lens, ensuring the cleanliness and transparency of the lens.

[0004] In the prior art, when the dual-light gas detection equipment cleans the detector lens, the brush head will inevitably pass through the monitoring area of the lens when it swings, which will directly block the lens of the detector, resulting in abnormal imaging or reduced imaging quality. In addition, the brush head is generally set outside the equipment. The brush head in the external environment may be affected by natural factors such as wind and rain, resulting in the cleaning effect being less than expected. Utility Model Content

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Reference Figure 1-Figure 5 , a dual-light gas detection device, comprising:

[0042] A pan-tilt unit 1; a thermal imaging unit 2, which is installed on the pan-tilt unit 1 and is used to capture and transmit infrared thermal radiation information; a visible light imaging unit 3, which is installed on the pan-tilt unit 1 and is used to capture and transmit images within the visible light range; the thermal imaging unit 2 includes a protective member 202 and two cleaning members 208; wherein the protective member 202 is installed in the thermal imaging unit 2, and the protective member 202 is arc-shaped and is used to provide protection for the lens of the thermal imaging unit 2, and the protective member 202 is configured to be able to move around the lens of the thermal imaging unit 2, and during the movement, the protective member 202 can still maintain protection for the lens of the thermal imaging unit 2; the two cleaning members 208 are both installed in the thermal imaging unit 2, connected to the protective member 202, and are configured to clean the surface of the protective member 202 when the protective member 202 moves.

[0043] The arc-shaped design of the protective member 202 can effectively prevent dust, dirt and other contaminants from adhering to the lens, ensuring the accurate capture and transmission of infrared thermal radiation information. At the same time, the protective member 202 can move around the lens, not only providing all-round protection for the lens, but also maintaining effective protection for the lens at different angles and positions. The cleaning member 208 can automatically clean the surface of the protective member 202 when it moves, effectively removing dust and dirt that may accumulate, and the cleaning member 208 and the protective member 202 are both arranged in the thermal imaging part 2 to avoid damage caused by interference from the external environment, thereby ensuring the cleanliness of the surface of the protective member 202 and not blocking the lens when cleaning the lens of the thermal imaging part 2.

[0044] Reference Figure 3 and Figure 4 The cleaning member 208 includes a cleaning head 209 , which is installed on one side of the cleaning member 208 . The cleaning head 209 is attached to one side of the protective member 202 and is used to clean the protective member 202 .

[0045] The cleaning head 209 is made of microfiber cloth or ultra-fine fiber. The microfiber cloth is delicate and soft, and does not generate static electricity, thus avoiding the absorption of more dust. The cleaning head 209 in the cleaning member 208 fits tightly against one side of the protective member 202, ensuring that the dirt and dust on the surface of the protective member 202 can be effectively removed when the protective member 202 moves. This fitting design not only ensures the cleaning effect, but also makes the cleaning process more stable and reliable.

[0046] Reference Figure 4 and Figure 5The protective member 202 includes: two protective plates 203, which are installed on the protective member 202; two assembly holes 204 are opened on one side of the protective member 202, and the protective plates 203 are installed in the assembly holes 204; a rack 205 is installed on one side of the protective member 202; the thermal imaging part 2 also includes: a gear 207, which is installed in the thermal imaging part 2 and connected to the rack 205; a power source 206, which is installed in the thermal imaging part 2, and the power shaft of the power source 206 is connected to the gear 207, which is used to provide power for the gear 207.

[0047] The protective plate 203 is made of transparent material. The protective plate 203 will not affect the lens shooting in the thermal imaging part 2 during movement. The rack 205 adopts a soft rack 205, which can be attached to the surface of the protective member 202. The power source 206 is connected to the gear 207 through its power shaft to provide a stable and reliable power source for the gear 207. The close fit between the gear 207 and the rack 205 enables the protective member 202 to move according to the preset path and speed, thereby realizing all-round protection and cleaning of the lens. The power source 206 adopts a micro servo motor and can also adopt a micro stepping motor.

[0049] The cleaning member 208 is detachably mounted in the assembly hole 210. This design not only improves the installation stability of the cleaning member 208, but also makes the replacement and maintenance of the cleaning member 208 more convenient. When the cleaning member 208 is worn or needs to be replaced, the user can easily remove the old cleaning member 208 and install a new cleaning member 208 without performing complicated disassembly operations on the entire thermal imaging unit 2. The through hole 201 opened at the front end of the thermal imaging unit 2 provides a suitable space for the installation of the protective member 202.

[0050] Reference Figure 1 Two protective covers 4 are respectively installed on the top of the visible light imaging part 3 and the thermal imaging part 2 to provide protection for the visible light imaging part 3 and the thermal imaging part 2, which significantly improves the protection performance of the dual-spectrum gas online monitoring gimbal. The two protective covers 4 can not only effectively prevent external objects from directly impacting the imaging part, but also resist the damage of harsh environments such as rain, dust and other natural factors to the imaging part.

[0051] During use, the pan-tilt unit 1 serves as a support and rotating platform for the entire detection equipment, and can drive the thermal imaging unit 2 and the visible light imaging unit 3 to rotate in the horizontal and vertical directions so as to monitor the target area in all directions. The thermal imaging unit 2 is installed on the pan-tilt unit 1, and detects gas leakage in the target area by capturing and transmitting infrared thermal radiation information. The internal protective member 202 of the thermal imaging unit 2 plays a vital role. The protective member 202 is arranged in an arc shape around the lens of the thermal imaging unit 2 to provide effective protection for it, prevent dust, dirt and other pollutants from adhering to the lens, and ensure the accurate capture and transmission of infrared thermal radiation information. The protective member 202 can surround the lens Move, through the cooperation of the gear 207 and the rack 205, and the drive of the power source 206, it moves according to the preset path and speed. During the movement, the protective member 202 can still maintain the protection of the lens of the thermal imaging part 2. When the protective member 202 moves, the cleaning head 209 in the cleaning member 208 fits tightly with one side of the protective member 202, effectively removing the dirt and dust on the surface of the protective member 202. The cleaning head 209 adopts microfiber cloth or ultra-fine fiber material, which is delicate and soft and does not generate static electricity, thereby ensuring the efficiency and stability of the cleaning process. When the cleaning member 208 is worn or needs to be replaced, the user can easily remove the old cleaning member 208 and install a new cleaning member 208.

[0052] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0053] While the arc-shaped protective member 202 provides protection for the lens of the thermal imaging unit 2, the protective member 202 can move around the lens of the thermal imaging unit 2, and during the moving cleaning process, the protective member 202 can still maintain protection for the lens of the thermal imaging unit 2.
