Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, specifically to a monitoring device for thermal power plant equipment. Background Technology

[0002] Thermal power plants, as crucial facilities for electricity production, rely on burning large quantities of fossil fuels (such as coal, oil, or natural gas) to generate heat energy, which is then converted into electrical energy. In this process, the raw material workshop plays a vital role, as it is responsible for storing, processing, and transporting these fuels to the combustion equipment. Dust generation is unavoidable in the raw material workshop; these particles, suspended in the air, form what we call dust. Surveillance cameras are installed in the raw material workshop to monitor the situation in real time. However, dust in the raw material workshop gradually covers and obscures the lens caps of the cameras, resulting in unclear monitoring images. This necessitates constant manual cleaning of the lens caps, increasing labor costs and posing a safety hazard. Utility Model Content

[0003] The main purpose of this utility model is to provide a monitoring device for thermal power plant equipment to solve the problems of manual cleaning of lens caps in the existing technology, which increases labor costs and is dangerous.

[0004] To achieve the above objectives, this utility model provides a monitoring device for thermal power plant equipment, including a camera body, a lens cover at the front end of the camera body, the lens cover being a rectangular transparent glass, and also including a rectangular frame, a housing, and a drive component;

[0005] The rectangular frame is fixedly connected to the camera body and is located directly in front of the lens cover. The upper and lower edges of the rectangular frame have grooves along their length.

[0006] One side of the casing is an open structure, which is fixedly set on the lower edge of the rectangular frame;

[0007] Inside the housing, a guide rod and a threaded rod are rotatably mounted. The threaded rod has a left helical section and a right helical section. Both the left helical section and the right helical section are threadedly fitted with moving blocks, and both are slidably fitted on the guide rod.

[0008] Each movable block is fixedly equipped with a movable rod, and the end of the movable rod away from the movable block passes through the open structure and two sliding grooves in sequence.

[0009] Each movable lever is equipped with a scraper, and each scraper is in contact with the lens cap;

[0010] One end of the threaded rod is connected to a drive component that drives its rotation.

[0011] Preferably, the driving component is a motor, the motor base is fixedly connected to the housing, and the output shaft passes through the housing and is fixedly connected to one end of the threaded rod.

[0012] Preferably, the scraper is made of rubber.

[0013] Preferably, the upper frame of the rectangular frame is fixedly connected to an extension plate, and multiple nozzles are fixedly arranged on the extension plate along its length, with the water outlets of the multiple nozzles all facing the lens cover.

[0014] Preferably, a U-shaped cover is fixedly connected to the camera body.

[0015] Preferably, the monitoring device for thermal power plant equipment also includes a bracket, on which the camera body is rotatably mounted, and the bracket is fixedly connected to a flange.

[0016] The beneficial effects of the above scheme are:

[0017] This design is suitable for dual-lens surveillance cameras. Most existing cameras are dual-lens surveillance cameras, with the two shooting holes symmetrically positioned on either side of the lens cover. When dust from the raw material workshop gradually covers and obscures the lens cover of the camera body, the drive mechanism starts working. This mechanism drives a threaded rod to rotate. The threaded rod has left-hand and right-hand helical sections. Two moving blocks begin to move towards the center of the lens cover. These moving blocks, via moving rods, drive scrapers. The scrapers, during this movement, remove dust from the lens cover of the camera body, thus eliminating the need for manual cleaning of the lens cover. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example:

[0037] like Figures 1-4 As shown, this embodiment provides a monitoring device for thermal power plant equipment, including a camera body 1. The front end of the camera body 1 has a lens cover 2, which is a rectangular transparent glass. The monitoring device also includes a rectangular frame 10, a housing 20, and a drive component 80. The rectangular frame 10 is fixedly connected to the camera body 1 and is located directly in front of the lens cover 2. Sliding grooves 11 are formed along the length of both the upper and lower edges of the rectangular frame 10. One side of the housing 20 is an open structure, which is fixedly located on the lower edge of the rectangular frame 10. Figure 3 , Figure 4As shown, a guide rod 30 (which can also be fixedly connected to the housing, either is acceptable) and a threaded rod 40 are rotatably mounted inside the housing 20. The threaded rod 40 has a left-hand helical section 41 and a right-hand helical section 42. Both the left-hand helical section 41 and the right-hand helical section 42 are screwed onto a moving block 50, and both are slidably mounted on the guide rod 30. Each moving block 50 is fixedly mounted with a moving rod 60. The end of the moving rod 60 away from the moving block 50 passes through the open structure and two sliding grooves 11 in sequence. Each moving rod 60 is fixedly mounted with a scraper 70, and each scraper 70 contacts the lens cap 2. The scraper 70 is made of rubber to prevent the scraper 70 from scratching the lens cap 2. One end of the threaded rod 40 is connected to a drive component 80 for driving its rotation. The drive component 80 is a motor, the motor base is fixedly connected to the housing 20, and the motor output shaft passes through the housing 20 and is fixedly connected to one end of the threaded rod 40.

[0038] This design is applicable to dual-lens surveillance cameras. Most existing camera bodies 1 are dual-lens surveillance cameras, with two shooting holes 3 symmetrically positioned on either side of the lens cover 2. When dust from the raw material workshop gradually covers and obscures the lens cover 2 of the camera body 1, the drive mechanism 80 starts working, causing the threaded rod 40 to rotate. The threaded rod 40 has a left-hand helical section 41 and a right-hand helical section 42. Two moving blocks 50 begin to move towards the center of the lens cover 2. The moving blocks 50, via the moving rod 60, drive the scraper 70 to move. During the movement of the two moving rods 60, the scraper 70 scrapes away the dust from the lens cover 2 of the camera body 1. This design avoids the need for manual cleaning of the lens cover 2.

[0039] An extension plate 90 is fixedly connected to the upper frame of the rectangular frame 10. Multiple nozzles 91 are fixedly mounted on the extension plate 90 along its length, with the water outlets of all nozzles 91 facing the lens cover 2. All nozzles 91 are connected to a prior art water supply device (the water supply device is existing technology and only needs to provide a water source to the nozzles; details are omitted). When dust from the raw material workshop gradually covers and obscures the lens cover 2 of the camera body 1, the water supply device is activated to provide water. Water is sprayed from the multiple nozzles 91 onto the lens cover 2, cleaning dust and stains from the lens cover 2 and the scraper 70. Furthermore, the drive mechanism 80 starts working, causing the threaded rod 40 to rotate. The moving block 50 moves the scraper 70 via the moving rod 60. During the movement of the two moving rods 60, the scraper 70 scrapes away water stains from the lens cover 2 of the camera body 1. A U-shaped cover 100 is fixedly connected to the camera body 1. The monitoring device for thermal power plant equipment also includes a bracket 200, on which the camera body 1 is rotatably mounted. The bracket 200 is fixedly connected to the flange 201.

[0040] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
