Description

Technical Field

[0001] This invention relates to the field of monitoring device technology, and in particular to a monitoring device for thermal control automation equipment. Background Technology

[0002] Surveillance devices refer to the general term for devices that use cameras and storage equipment to record and store video and audio signals. With the increasing prevalence of closed-circuit surveillance in civilian and commercial applications, surveillance cameras are widely used in various locations such as residential buildings, villas, shopping malls, financial offices, and thermal power plants, safeguarding enterprise management and public security. In thermal power plants, to ensure the safe operation of thermal control automation equipment, surveillance devices are typically deployed around it to monitor the equipment status in real time.

[0003] The environment in thermal power plants is relatively harsh, with high dust concentrations. Dust easily accumulates on the exterior walls and lenses of surveillance cameras, leading to a decrease in image clarity. Traditional maintenance methods involve manually wiping the lenses with a damp towel to remove the accumulated dust.

[0004] However, the surveillance cameras in thermal power plants are generally installed at a height of more than 3 meters. When wiping them, ladders or lifting platforms are needed, and workers face the risk of falling while working at height. In addition, repeated rubbing with wet towels can easily form fine scratches on the lens surface, which will reduce the light transmittance and affect the quality of the surveillance images after long-term use.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention employs a non-contact dust removal solution using "high-pressure gas + mobile blowing". A servo motor drives a push plate to move, which in turn drives a moving frame via a spring. The moving frame brings the curved tube close to the lens, and a solenoid valve instantly releases a high-pressure pulse airflow. At this point, the moving frame moves to the end of the dovetail groove and stops moving, while the push plate continues to move, causing the curved tube to rotate around the camera. This releases a high-pressure pulse airflow that forms a fan-shaped air curtain through the first air hole, removing dust from the lens surface in one go. This avoids the risk of falling during manual cleaning from heights and eliminates scratches on the lens surface caused by repeated rubbing with a wet towel, significantly improving maintenance safety and extending the lens's lifespan.

[0014] 2. This invention integrates a high-pressure gas generator within the mounting box. The rotation of the threaded rod drives the eccentric wheel and connecting rod to move, causing the sleeve piston to reciprocate and automatically replenish clean compressed air to the high-pressure tank, forming a closed-loop air source. At the same time, the filter element in the mounting box performs secondary filtration of the ambient air entering the sleeve, preventing corrosive particles such as coal dust and sulfides from entering the air path, ensuring stable purging air pressure and preventing secondary contamination of the lens during long-term operation.

[0015] 3. During maintenance, this invention only requires rotating the camera, and the ball bearings automatically disengage from the groove, allowing the camera and the locking plate to be pulled out of the insertion slot as a whole. This enables a single person to perform lens repair or replacement on the ground. During installation, the locking plate is inserted into the slot, and the ball bearings automatically embed into the groove under the action of the first spring, forming an anti-rotation lock. This ensures that the camera maintains its initial angle in the environment of thermal power plants with strong vibrations and high temperature gradients, preventing the monitoring image from shifting and improving the image recognition reliability of the thermal control automation system.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-10 As shown, the present invention has the following three specific embodiments.

[0020] Example 1

[0021] A monitoring device for thermal control automation equipment includes a mounting base 1. The lower end face of the mounting base 1 has a plug-in groove 12 and a dovetail groove 11. A pair of dovetail grooves 11 are provided on the front and rear sides of the plug-in groove 12. A retaining groove 13 is provided inside the plug-in groove 12, and a mounting hole 14 is provided on the inner wall of the retaining groove 13. A mounting box 5 is fixedly connected to the lower right side of the mounting base 1. The device also includes: Camera 2, with a connecting rod 21 fixedly connected to the upper end of camera 2, and a card plate 22 fixedly connected to the upper end of connecting rod 21. Card plate 22 is located inside card slot 13 and is engaged with it. A groove 221 is provided on the upper surface of card plate 22. Anti-rotation component 3 is installed inside the mounting hole 14 and is used to abut against the card plate 22. The movable frame 4 has a dovetail block fixedly connected to its upper end. The dovetail block is located inside the dovetail groove 11 and is slidably connected to it. An air pipe 41 is rotatably connected inside the movable frame 4. A bent pipe 42 is fixedly connected to the upper end of the air pipe 41. A first air hole 421 is equidistantly opened at one end of the concave surface of the bent pipe 42. A connecting pipe 43 is fixedly connected inside the movable frame 4. The lower end of the air pipe 41 passes through the interior of the connecting pipe 43 and is rotatably connected to it. The lower end of the connecting pipe 43 passes through the lower end of the movable frame 4. Drive mechanism 6 is installed on the front side of mounting box 5. Drive mechanism 6 is used to drive the bent pipe 42 to move in the direction of camera 2. High pressure tank 7; High pressure tank 7 is fixedly connected inside the installation box 5. A hose 8 is fixedly connected to the side wall of high pressure tank 7. The end of hose 8 is fixedly connected to the lower end of connecting pipe 43. A solenoid valve 81 is fixedly connected to the right side of hose 8. High-pressure gas generator 9 is installed inside the mounting box 5. High-pressure gas generator 9 fills high-pressure tank 7 with high-pressure gas. The anti-rotation component 3 includes a movable block 31, which is located inside the mounting hole 14 and slidably connected thereto. A rolling groove 311 is provided on the lower end face of the movable block 31, and a ball 33 is slidably connected inside the rolling groove 311. The lower end of the ball 33 is embedded in the groove 221. A first spring 32 is fixedly connected to the upper end of the movable block 31, and the upper end of the first spring 32 is fixedly connected to the top wall of the mounting hole 14. A second air hole 51 is provided on the right end face of the installation box 5. An installation box 52 is fixedly connected to the inner wall of the right side of the installation box 5. The installation box 52 is located to the left of the second air hole 51. A filter element 53 is fixedly connected inside the installation box 52.

[0022] In this embodiment, as Figures 1-7As shown, when camera 2 is in working condition, the moving frame 4 is away from camera 2, the curved pipe 42 is in the retracted position with its protrusion facing to the right, and the high-pressure tank 7 has a sufficient amount of high-pressure gas stored in it. When the central control room issues a "dust removal" command, the drive mechanism 6 starts first, moving the moving frame 4 so that the curved pipe 42 gradually approaches camera 2. The drive mechanism 6 continues to drive, causing the curved pipe 42 to rotate around camera 2. After the arrival signal is triggered, the solenoid valve 81 opens instantly, and the clean gas in the high-pressure tank 7 goes directly to the curved pipe 42 through the hose 8, connecting pipe 43, and air pipe 41. It is then sprayed out at high speed in a fan shape from the first air hole 421, forming an air curtain covering the entire mirror surface. Dust is stripped off and dispersed downwards with the airflow. The solenoid valve 81 closes, the drive mechanism 6 reverses, the moving frame 4 returns to its initial position, the curved pipe 42 leaves the field of view, and camera 2 resumes clear viewing. During the continuous rotation of the threaded rod 61, the high-pressure gas generating mechanism 9 pressurizes the outside air filtered by the filter element 53 into the high-pressure tank 7, replenishing the air source for the next dust removal cycle. The entire process requires no manual climbing or contact with the lens by any wiping material. During maintenance, simply rotate the camera 2, and the ball bearing 33 will automatically disengage from the groove 221, allowing the camera 2 and the locking plate 22 to be pulled out of the insertion slot 12 as a whole, enabling single-person ground operation to complete lens repair or replacement. During installation, the locking plate 22 is inserted into the slot 13, and the ball bearing 33 automatically embeds into the groove 221 under the action of the first spring 32, forming an anti-rotation lock. This ensures that the camera 2 maintains its initial angle in the strong vibration and high temperature gradient environment of the thermal power plant, preventing the monitoring image from shifting and improving the image recognition reliability of the thermal control automation system.

[0023] Example 2

[0024] The difference from Embodiment 1 is that this embodiment discloses the specific structure of the drive mechanism 6; The drive mechanism 6 includes a pair of threaded rods 61, which are rotatably connected to the left end of the mounting box 5. The right end of the threaded rod 61 rotatably passes through the interior of the mounting box 5. A sleeve rod 63 is threadedly connected to the side wall of the threaded rod 61. A push plate 62 is fixedly connected to the right end of the sleeve rod 63. The left end of the sleeve rod 63 passes through the movable frame 4 and is slidably connected to it. A stop plate is fixedly connected to the side wall of the sleeve rod 63 located on the left side of the movable frame 4. A second spring 64 is sleeved on the side wall of the sleeve rod 63. The right end of the second spring 64 is fixedly connected to the left end of the push plate 62 and the left end of the second spring 64 is fixedly connected to the right end of the movable frame 4. The threaded rod 61 inside the mounting box 5 is connected to the side wall via a sprocket assembly 65. A servo motor 66 is fixedly connected to the inner wall of the mounting box 5 via a fixing bracket. The output shaft end of the servo motor 66 is fixedly connected to the right end of the front threaded rod 61. The drive mechanism 6 includes a gear 68. The movable frame 4 has an installation cavity inside. The gear 68 is fixedly connected to the side wall of the air pipe 41 and is located inside the installation cavity. The side wall of the gear 68 is meshed with a rack 67. The right end of the rack 67 is fixedly connected to the left end of the push plate 62.

[0025] In this embodiment, as Figures 7-8 As shown, after the servo motor 66 is powered on, it synchronously drives the two threaded rods 61 to rotate. The sprocket assembly 65 ensures that the two rods rotate at the same speed. The sleeve rod 63, which meshes with the threaded rod 61, is converted into linear motion when the rotational motion is restricted. The push plate 62 pushes out to the left, the second spring 64 is compressed and pushes the moving frame 4 to slide smoothly along the dovetail groove 11. The rack 67 fixed on the push plate 62 moves forward synchronously. When the moving frame 4 moves to the leftmost end, the air pipe 41 is located directly below the camera 2. The push plate 62 continues to move, and the rack 67 moves the gear 68 fixed to the air pipe 41, causing the air pipe 41 to rotate inside the moving frame 4. The concave surface of the curved pipe 42 then rotates around the camera 2. High-requirement gas is discharged from the first vent 421 to remove dust from the lens of camera 2. After dust removal, servo motor 66 reverses, push plate 62 moves backward, and second spring 64 returns to its original shape. After second spring 64 returns to its original shape, the protrusion of bent tube 42 faces right. At the same time, the abutment on the left side of sleeve rod 63 pushes the moving frame 4 to move, so that the moving frame 4 quickly returns to its original position, completing a full cycle of "extend-rotate-blow-return". The whole process is driven by the same power source, with a compact structure and good synchronization.

[0026] Example 3

[0027] The difference from Embodiment 2 is that this embodiment discloses the specific structure of the high-pressure gas generating mechanism 9; The high-pressure gas generating mechanism 9 includes a sleeve 94, which is fixedly connected inside the mounting box 5. A piston 931 is slidably connected inside the sleeve 94. An air inlet pipe 9541 is fixedly connected to the rear side wall of the sleeve 94. A first one-way valve 951 is fixedly connected inside the air inlet pipe 9541. An air outlet pipe 9641 is fixedly connected to the front end of the sleeve 94. The end of the air outlet pipe 9641 is fixedly connected to the side wall of the high-pressure tank 7. A second one-way valve 961 is fixedly connected inside the air outlet pipe 9641. The high-pressure gas generating mechanism 9 also includes an eccentric wheel 91, which is fixedly connected to the right end of the rear threaded rod 61. A connecting rod 92 is hinged to the right end of the eccentric wheel 91, and a moving rod 93 is hinged to the lower end of the connecting rod 92. The lower end of the moving rod 93 is fixedly connected to the upper end of the piston 931.

[0028] In this embodiment, as Figures 9-10As shown, the rear threaded rod 61 drives the eccentric wheel 91 to rotate synchronously during rotation. The connecting rod 92, which is hinged to the edge of the eccentric wheel 91, moves up and down reciprocatingly, and transmits the reciprocating motion to the piston 931 through the moving rod 93. When the piston 931 moves upward, the volume of the inner cavity of the sleeve 94 increases, forming a negative pressure. Outside air is drawn into the sleeve 94 through the second air hole 51, filter element 53, air inlet pipe 9541 and first one-way valve 951. When the piston 931 moves downward, the volume of the inner cavity decreases. The air is compressed and opens the second one-way valve 961. It is continuously injected into the high-pressure tank 7 through the air outlet pipe 9641, realizing the self-pressurization function of driving and charging at the same time. Every time the bend pipe 42 completes a dust removal, the pressure in the high-pressure tank 7 is replenished in real time to ensure that the next spray still has sufficient impact force. The entire air source generation and dust removal action share the same rotational power, requiring no additional energy consumption. The structure is simple and easy to maintain.

[0029] The working principle of this invention is as follows: When the camera 2 is working normally, the moving frame 4 is in the initial position away from the camera 2, the protrusion of the bent pipe 42 faces to the right, and the lens field of view is unobstructed; the high pressure tank 7 is filled with clean high pressure air continuously replenished by the high pressure gas generating mechanism 9; When the control room issues a dust removal command, the servo motor 66 drives the two threaded rods 61 to rotate synchronously, and the sprocket assembly 65 ensures that the two rods rotate at the same speed. The sleeve rod 63, which meshes with the threaded rod 61, converts the rotational motion into linear motion. The push plate 62 moves to the left and compresses the second spring 64, pushing the moving frame 4 to slide smoothly along the dovetail groove 11 toward the camera 2. The rack 67, which is fixed to the push plate 62, moves forward synchronously. When the moving frame 4 reaches the leftmost end and the air pipe 41 is located directly below the camera 2, the rack 67 continues to move the gear 68, which is fixed to the air pipe 41, so that the air pipe 41 rotates inside the moving frame 4. The concave surface of the curved pipe 42 then hugs the outer periphery of the lens and rotates around it. When the mobile frame 4 reaches the leftmost end, the positioning signal is triggered, the solenoid valve 81 opens instantly, and the clean gas in the high-pressure tank 7 passes through the hose 8, connecting pipe 43, and air pipe 41 to the bend 42. It is then sprayed out at high speed in a fan shape from the first air hole 421, forming an air curtain covering the entire mirror surface. Dust is peeled off and dispersed downward with the airflow. The solenoid valve 81 closes, and the blowing ends. Throughout the process, the rear threaded rod 61 simultaneously drives the eccentric wheel 91 to rotate, which in turn drives the piston 931 to reciprocate within the sleeve 94 via the connecting rod 92 and the moving rod 93. When the piston 931 moves upward, outside air is drawn in through the filter element 53, the air inlet pipe 9541, and the first one-way valve 951. When the piston 931 moves downward, the air is compressed and continuously injected into the high-pressure tank 7 through the air outlet pipe 9641 and the second one-way valve 961, achieving a self-pressurizing cycle of simultaneous driving and air replenishment, thus reserving air pressure for the next dust removal cycle. This completes one fully automatic closed-loop dust removal cycle of "extension-rotation-blowing-retraction-air replenishment," without requiring manual climbing or any contact between the lens and any cleaning material.

[0030] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
