Description

Technical Field

[0001] The utility model relates to the technical field of safety protection, in particular to a mining intrinsically safe camera for observing belt tearing. Background Art

[0002] In the coal mining process, the mined coal is transported out of the mine through a belt conveyor, so the normal operation of the belt conveyor is an important guarantee to ensure coal mining.

[0003] Due to long-term use and the harsh working environment in the mine, the belts used in the coal conveyor belt conveyor are easily torn and damaged, which in turn causes the belt to break and affects the normal operation of coal mining. Therefore, belt tearing cameras are installed along the coal conveyor belt conveyor to monitor the operation of the belt in real time through cameras and infrared lasers, and timely detect and warn of damage such as tearing.

[0004] In the currently configured cameras, the cameras and infrared lasers used are each equipped with corresponding window glass to prevent dust from entering and affecting the clarity of the shooting. However, during use, the flying dust in the mine is easy to adhere to the surface of the window glass, causing blurred pictures. Therefore, the window surface needs to be cleaned manually frequently. Once the operator is negligent and fails to clean the window surface in time, it will be detrimental to the real-time monitoring effect of the belt. Summary of the invention

[0005] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a mining intrinsically safe camera for observing belt tearing which can improve the shooting clarity and ensure the stable and normal operation of the coal conveyor belt conveyor.

[0007] In order to improve the shooting clarity, a first wiper for scraping off water on the surface of the window glass is installed on the upper surface of the cover, and a second wiper for scraping off water on the surface of the lamp window is installed on the cover plate.

[0008] Furthermore, a flippable first dust cover is hinged on the cover, a second dust cover is installed on the cover plate, and a light-transmitting hole corresponding to the position of the lamp window is opened on the surface of the second dust cover.

[0009] Furthermore, a bracket for installing the solenoid valve is fixed on the side of the box.

[0010] Furthermore, a water pipe support is fixed on the upper surface of the box body, and the main water outlet pipe is fixed on the water pipe support by a pipe clamp.

[0011] The beneficial effect of the utility model is that the utility model controls the connection and disconnection between the three-way water inlet and the water outlet through the power on or off of the electromagnetic valve, thereby spraying water on the window glass surface and the lamp window surface for cleaning, thereby ensuring that the window glass and the lamp window surface are clean and transparent, which is beneficial to improving and stabilizing the clarity of the captured image.

DETAILED DESCRIPTION

[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] like Figure 1 to Figure 3The illustrated example is a mining intrinsically safe camera for observing belt tearing, which comprises a rectangular box body 1, the bottom of which is open and fixedly connected to a box cover 22, and box feet 23 for mounting the camera on a conveyor belt are respectively fixed at the four corners of the bottom of the box cover 22, and mounting holes are provided on the box feet 23.

[0019] A camera 2 is installed at the upper part of the box 1, and an infrared laser 3 is installed at the lower part of the box 1. The infrared laser 3 monitors the running condition of the belt used by the belt conveyor. The camera 2 is used to photograph the tearing phenomenon of the belt. A control main board is installed in the middle part of the box 1 through the bottom plate.

[0020] A cover 4 is fixed to the upper surface of the box body 1 , and a cover plate 5 is installed at the lower part. A window glass 6 corresponding to the position of the camera 2 is installed on the upper surface of the cover 4 , and a light window 7 corresponding to the position of the infrared laser 3 is embedded on the cover plate 5 .

[0021] A bracket 19 is fixed on the side of the box body 1, and a solenoid valve 8 is installed on the bracket 19. The control end of the solenoid valve 8 is connected to a tee 9, the water inlet end of the tee 9 is connected to an external water inlet pipe, and the water outlet end of the tee 9 is connected to a water outlet main pipe 10. The solenoid valve 8 controls the connection and disconnection between the water inlet end and the water outlet end of the tee 9; a water pipe support 20 is fixed on the upper surface of the box body 1, and the water outlet main pipe 10 is fixed on the water pipe support 20 by a pipe clamp 21.

[0022] The water outlet end of the water outlet main pipe 10 is respectively connected to the first water outlet branch 11 and the second water outlet branch 12. The water outlet end of the first water outlet branch 11 is installed with a first nozzle 13 for spraying water to the surface of the window glass 6, and the water outlet end of the second water outlet branch 12 is installed with a second nozzle 14 for spraying water to the surface of the lamp window 7.

The structures of the first wiper 15 and the second wiper 16 are basically similar to those of the wipers used in automobiles.

[0025] When the camera with such a structure monitors the belt of the belt conveyor, if there is too much dust on the surface of the window glass 6 and the light window 7, resulting in insufficient clarity of the image captured, the electromagnetic valve 8 can be controlled to connect the external water to the water outlet main pipe 10, and the first nozzle 13 on the water outlet end of the first water outlet manifold 11 can spray water onto the surface of the window glass 6 to clean the surface of the window glass 6, or the second nozzle 14 on the water outlet end of the second water outlet manifold 12 can spray water onto the surface of the light window 7 to clean the surface of the light window 7, thereby ensuring that the surface of the window glass 6 and the light window 7 are clean and transparent, and improving the clarity of the image captured.

[0026] If there is too much water on the surface of the window glass 6 or the lamp window 7 after water spray cleaning, the first wiper 15 can be started to scrape off the excess water on the surface of the window glass 6, or the second wiper 16 can be started to scrape off the excess water on the surface of the lamp window 7.
