Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4 , a kind of observation connection production indicating signal device in the figure, including camera 101 and the lens of being arranged in camera 101, lens is composed of lens barrel 102 and the lens 103 of being arranged in lens barrel 102, still including the dust removal assembly of being arranged in camera 101 for dust removal to lens 103;

[0022] Dust removal assembly includes mounting ring 201 arranged on the side close to lens 103 of camera 101, mounting ring 201 is sleeved to the side wall of lens barrel 102, mounting ring 201 is connected with the shell of camera 101 by a plurality of screws, the side away from the bottom of camera 101 of mounting ring 201 is connected with gas tank 202 by U-shaped frame 206, the side close to lens 103 of gas tank 202 is fixedly connected with gas outlet pipe 203, the side wall of lens barrel 102 is fixedly connected with arc-shaped pipe 204, the side close to lens 103 of arc-shaped pipe 204 is fixedly connected with a plurality of dust removal pipes 207, each dust removal pipe 207 is inclined downward, mounting ring 201 is equipped with auxiliary assembly for assisting in the process of dust removal to lens 103, the shell of camera 101 is equipped with gas conveying pipe 205, one end of gas conveying pipe 205 is connected with external gas source, the other end of gas conveying pipe 205 is connected with the side away from gas outlet pipe 203 of gas tank 202;

[0023] It needs to be explained here that: through the setting of dust removal assembly, under the cooperation of auxiliary assembly, while realizing the dust removal effect to lens 103, compared with the existing dust removal mode, the interference to lens shooting can be reduced, so that the continuity and comprehensiveness of camera 101 observing signal indicating lamp are improved.

[0024] It is worth noting that the model number of camera 101 is...

[0025] The lens of the DS-2CC11A2P(N)-(IR3)(IR5) camera 101 mainly consists of an optical lens 103, an aperture mechanism, a focusing mechanism, a lens barrel 102, and an interface. Since external dust mainly falls on the external optical lens 103, the optical lens 103 is emphasized here.

[0026] Please see Figures 2-4 The auxiliary components shown in the figure include two symmetrically arranged arc-shaped plates 301 that are slidably connected to the mounting ring 201 on the side away from the camera 101. Multiple rubber rods 302 are fixedly connected to the side of the two arc-shaped plates 301 that are close to each other. The air box 202 is provided with a drive assembly for driving each rubber rod 302.

[0027] It should be noted that the auxiliary components allow the lens 103 to receive slight vibrations, which helps the dust overcome its adhesion, loosens and removes the dust particles, thereby improving the cleaning effect on the lens 103.

[0028] It is worth noting that the modern camera 101 is designed and manufactured with a certain degree of anti-interference capability in mind. The lens is usually fixed to the main body of the camera 101 through a stable bayonet or threaded connection. This connection method can withstand a certain degree of slight vibration and ensures that the optical axis of the lens is relatively stable. In addition, the camera 101 is equipped with image stabilization technology (optical image stabilization or electronic image stabilization). Therefore, when there is slight vibration at the lens, these image stabilization mechanisms can reduce the impact of vibration on image stability to a certain extent. Moreover, the energy generated by slight vibration is small and not enough to cause displacement or damage to the internal precision components of the camera 101 (such as sensors, image processors, etc.). Therefore, it will not interfere with the normal working state of the camera 101.

[0029] Working principle: The production instruction signal system is used to transmit production instructions, status information, and operation prompts during continuous production. After the signal source generates a signal, it is sent to the signal receiver through the transmission line. During transmission, the signal undergoes encoding and modulation to improve transmission efficiency and anti-interference capability. At the receiving end, the signal receiver decodes and demodulates the received signal to restore it to the original production instruction information. Based on this information, it performs corresponding display or operation. At the final signal terminal, the production instruction signal is displayed intuitively through indicator lights of different colors and flashing frequencies (e.g., rapid flashing indicates an emergency, slow flashing indicates a general reminder).

[0030] In complex production lines, multiple processes and equipment need to work together. By observing the production line indicator signals, operators can clearly understand the working status of each link and the next operation, thereby ensuring the accuracy of the production process and timely detection of production anomalies. At the same time, observing the signals helps to optimize the production process, reduce waiting time and unnecessary operations. In some hazardous production environments, such as oil refineries and chemical plants, for safety reasons, cameras 101 are used to observe the production line indicator signals. The indicator signals can be presented to the monitoring personnel in real time in the form of images or videos, without the need for personnel to go to the site. This allows for remote observation of multiple indicator signals from centralized monitoring sites such as the control room, improving monitoring and observation efficiency while avoiding the safety risks of on-site observation by personnel.

[0031] Due to factors such as production equipment and environment in factories like oil refineries and chemical plants, dust can easily adhere to the lens of camera 101 due to van der Waals forces and electrostatic attraction. When it is necessary to clean the dust on the lens, firstly, the external air source is activated, so that high-pressure gas is delivered from the air supply pipe 205 to the air box 202, and then from the air box 202 to the arc-shaped pipe 204, and finally blown from each dust removal pipe 207 to the surface of the lens 103. Since each dust removal pipe 207 is located above the lens 103 and is set at an angle downward, the dust attached to the surface of the lens 103 can be blown away from the lens 103.

[0032] Meanwhile, as the high-pressure gas flows from the gas box 202 to each dust removal pipe 207, the rubber rods 302 on each arc plate 301 will reciprocate against the side wall of the lens barrel 102 under the action of the drive component and the reset component, thereby causing the lens barrel 102 to receive slight vibration. During slight vibration, the dust particles attached to the surface of the lens 103 will move relative to the surface of the lens 103 due to inertia. The dust adhesion force on the surface of the lens 103 usually includes van der Waals force, electrostatic attraction, etc. Therefore, the acceleration generated by slight vibration helps to overcome these adhesion forces, loosen the dust particles and remove them, thereby improving the cleaning effect on the lens 103. Thus, while achieving the dust removal effect on the lens 103, compared with the existing dust removal method, it can reduce the shooting interference of the lens, thereby improving the continuity and comprehensiveness of the camera 101's observation of the signal indicator lights.

[0033] Example 2

[0034] Please see Figure 4This embodiment further illustrates Example 1. The driving assembly shown in the figure includes a driving rod 401 rotatably connected to the air box 202. Multiple driving blades 402 are fixedly connected to the side wall of the driving rod 401. One end of the driving rod 401 near the mounting ring 201 passes through the air box 202 and is fixedly connected to a cam 403. Two arc-shaped plates 301 are fixedly connected to driving plates 404 at their close ends. The cam 403 is located between the two driving plates 404. The mounting ring 201 is provided with a reset assembly for resetting the two arc-shaped plates 301 after driving.

[0035] It should be noted that, through the configuration of the drive assembly, during the process of external high-pressure gas being delivered from the gas pipe 205 to the gas box 202, it will impact the side wall of the drive blade 402, thereby causing the drive blade 402 to rotate, which in turn causes the cam 403 at one end of the drive rod 401 to rotate. During the rotation of the cam 403, it will reciprocate against the two drive plates 404, thereby causing the two arc plates 301 to reciprocate against each other under the pushing force and the guiding and resetting action of the reset assembly, which in turn causes the rubber rods 302 on the arc plates 301 to reciprocate against the side wall of the lens barrel 102.

[0036] Please see Figure 4 The drive rod 401 in the diagram is eccentrically positioned relative to the gas pipe 205.

[0037] It should be noted here that by setting the drive rod 401 and the gas supply pipe 205 eccentrically, when the high-pressure gas is delivered from the gas supply pipe 205 to the gas box 202, it will impact the drive blade 402, thereby driving the drive blade 402 to rotate.

[0038] Please see Figure 2 and Figure 3 The reset assembly shown in the figure includes a fixed plate 501 fixedly connected to the mounting ring 201 near the arc plate 301. A reset tube 502 is fixedly connected to the fixed plate 501 near the drive plate 404. A reset rod 503 is slidably connected to the reset tube 502. One end of the reset rod 503 is connected to the drive plate 404. A spring 504 is sleeved on the side wall of the reset tube 502. The two ends of the spring 504 are respectively connected to the fixed plate 501 and the drive plate 404.

[0039] It should be noted here that the reset component is designed to provide guidance and reset for the movement of the arc plate 301.
