[0001] The invention relates to the field of monitoring equipment, and in particular to a monitoring equipment for coal mining. Background Art

[0002] During the coal mining process, monitoring equipment is usually set up to monitor the mining area in real time, so that managers can promptly discover problems on site from the monitoring devices.

[0003] When the monitoring equipment is used in some dusty scenes, the external dust will gradually adhere to the lens, which reduces the monitoring camera effect. The existing method is usually to set a corresponding brush or scraper next to the lens. When there is a lot of dust attached to the lens, the brush or scraper is controlled to move to clean the lens and remove the dust. However, the coal mining area is usually underground, and the aquifer is often penetrated during the mining process, resulting in groundwater infiltration, making the humidity in the coal mining area heavier. A large amount of dust such as coal ash is generated during the coal mining process. The coal ash and other dust are not only easy to adhere to the lens of the monitoring equipment, affecting the monitoring effect, but also under the action of moisture, the coal ash will condense and agglomerate on the lens. The coal ash agglomerated on the lens cannot be cleaned by simply cleaning with a brush or scraper, and the repeated brushing and cleaning will hinder the normal monitoring camera.

Through the engagement of the card slot 61 with the rib 41, the baffle 6 cooperates with the shell 2 to seal the upper half of the mirror 4 and isolate it from the outside world; the baffle 6 is fixedly connected to the drive motor 7, and the output shaft of the drive motor 7 passes through the baffle 6; the output shaft of the drive motor 7 is fixedly connected to the cleaning plate 8; the cleaning plate 8 is fixedly connected to the water pipe 9, and the water pipe 9 passes through the baffle 6; the water pipe 9 is connected to a number of water spray pipes 10; the shell 2 has through holes 01 on the left and right sides, and the through holes 01 are flush with the rib 41; the shell 2 has a cavity 21, and the through hole 01 is connected to the cavity 21; the lower side of the cavity 21 is connected to a number of drainage pipes 22.

[0032] The baffle plate 6 is fixedly connected to the arc-shaped baffle shell 13, and the arc-shaped baffle shell 13 is fixedly connected to the housing 2. The arc-shaped baffle shell 13 is used to shield and protect the mirror surface 4 to prevent the broken stones from falling and damaging the mirror surface 4.

[0033] The closer the water spray port on the water spray pipe 10 is to the drive motor 7, the larger the water spray port is. When the water spray pipe 10 sprays water on the surface of the mirror 4 to fully rinse off the fly ash attached to the surface of the mirror 4, the water spray pipe 10 sprays a larger amount of water on the groove 61 and the rib 41, and the water falling on the groove 61 and the rib 41 is flushed into the cavity 21 through the through hole 01.

[0034] It also includes a cooling fan 101; the cooling fan 101 is fixedly connected to the outer shell 2; an air inlet 10101 is opened on the rear side of the outer shell 2, and a filter is arranged at the air inlet 10101; the outer shell 2 is opened with a plurality of flow channels 02; the arc-shaped baffle shell 13 is opened with a plurality of air outlet holes 1301, and external air enters the inner part of the outer shell 2 from the air inlet hole 10101, dissipates heat to the camera 3 and other parts, and then enters the arc-shaped baffle shell 13 through the flow channel 02 and is blown out from the air outlet hole 1301.

[0035] The air outlet 1301 is arranged vertically downward, and the gas is blown downward through the air outlet 1301 , which can blow the front of the mirror 4 to disperse the coal ash and reduce the coal ash attached to the surface of the mirror 4 .

[0036] The housing 2 is slidably connected to the sliding ring 102 , and the sliding ring 102 is fixedly connected to the cleaning plate 8 , and the cleaning plate 8 is provided with a plurality of holes.

[0037] It also includes a ventilation pipe 11 and an air outlet pipe 12; the cleaning plate 8 is connected to the ventilation pipe 11, and the ventilation pipe 11 passes through the baffle 6 and the shell 2 and is connected to the flow channel 02; the cleaning plate 8 is connected to a plurality of air outlet pipes 12.

[0038] The cleaning plate 8 is configured as an arc-shaped plate, and the gas blown out of the gas outlet pipe 12 is guided by the cleaning plate 8 to blow along the surface of the mirror surface 4 to blow off and dry the residual water on the surface.

[0039] The drain pipe 22 is located at the lower side of the housing 2, so that the cleaned sewage is discharged away from the mirror surface 4, avoiding the discharged sewage from contacting the mirror surface 4 under the influence of wind.

[0040] When the monitoring device is in use, the whole device is manually installed and fixed in the coal mining area through the mounting plate 1, the power is turned on, and the water pipe 9 is connected to the external water supply mechanism. The subsequent management personnel use the camera 3 to shoot and monitor the mining area through the mirror 4; and the coal mining area will produce a large amount of dust such as coal ash, and the humidity in the coal mining area is heavy. With the continuous use of the monitoring device, the surface of the mirror 4 will gradually be adhered to the coal ash and other dust, thereby reducing the shooting effect of the camera 3, and the adhered coal ash and other dust will condense and agglomerate on the surface of the mirror 4 under the action of moisture; therefore, when the management personnel find that the surface of the mirror 4, that is, the lower half of the mirror 4 located in front of the camera 3, is adhered to a lot of coal ash and other dust, affecting the monitoring observation, the electric slip ring 5 is controlled to drive the mirror 4 to rotate 180 degrees through the linkage unit, so as to displace the mirror with coal ash and other dust. 4 is rotated upward and is located behind the baffle 6, and the upper half of the mirror 4 that is not in contact with the outside world is rotated downward and is located in front of the camera 3. At this time, the management personnel can still monitor and observe the coal mining area through the camera 3 through the clean mirror 4, and switch the use position of the mirror 4 by driving the mirror 4 to ensure the monitoring effect of the camera 3. In addition, by directly controlling the rotation of the mirror 4, the mirror 4 in front of the camera 3 can be quickly switched. Compared with the existing use of a cleaning mechanism to clean the surface of the mirror 4, the management personnel do not need to spend time waiting and can continue to monitor and observe the coal mining area through the camera 3; and an arc-shaped blocking shell 13 is provided on the upper side of the front of the mirror 4, and the arc-shaped blocking shell 13 is used to shield and protect the mirror 4 to avoid the use of debris falling from the equipment to damage the mirror 4 in the coal mining area.

[0041] Impurities such as soot are attached to the surface of the mirror 4. The existing method is usually to simply clean and scrape the soot and other impurities attached to the surface with a brush or a scraper. However, when the brush or scraper cleans the mirror 4, it is inevitable that scratches and scratches will be caused on its surface, making the surface of the mirror 4 incomplete, thereby affecting the monitoring and observation effect of the camera 3; therefore, when the electric slip ring 5 drives the mirror 4 to rotate 180 degrees through the linkage unit, at this time, the surface of the mirror 4 with dust such as soot attached rotates to the back of the baffle 6, and then the driving motor 7 is controlled to drive the cleaning plate 8 and other connected parts to rotate on the upper half of the mirror 4, and at the same time, the external water supply mechanism is controlled to transport water to the water supply pipe 9, and the water is sprayed through the water pipe 10 sprays water on the surface of the mirror 4. As the cleaning plate 8 rotates, the water pipe 10 washes away the coal ash and other impurities on the surface of the mirror 4. The washed away sewage falls on the ribs 41 and the grooves 61, flows into the cavity 21 through the through hole 01, and is finally discharged to the outside from the drain pipe 22. The water pipe 10 sprays water on the surface of the mirror 4 to wash away the coal ash and other impurities attached to the surface. Compared with the existing scraping cleaning, when cleaning the coal ash and other impurities, it can avoid scratching the surface of the mirror 4. It should be noted that after the mirror 4 rotates 180 degrees, the ribs 41 and the grooves 61 are engaged, so that the baffle 6 cooperates with the shell 2 and the upper half of the mirror 4 to maintain a sealed state, so as to avoid water leaking to the outside during the flushing process.

[0042] Furthermore, during the use of the equipment, by controlling the rotation of the cooling fan 101, the cooling fan 101 draws external air into the housing 2 through the air inlet 10101, dissipates the heat of the camera 3 and other parts inside the housing 2, and then enters the arc-shaped baffle shell 13 through the flow channel 02, and is blown out from the air outlet 1301 to prevent the camera 3 from overheating and being damaged. The air outlet 1301 is set vertically downward, and the gas is blown downward through the air outlet 1301, which can blow in front of the mirror 4 to disperse the coal ash and reduce the coal ash attached to the surface of the mirror 4; at the same time, after the water spray pipe 10 sprays water to rinse the mirror 4, there will still be residual water on the surface of the mirror 4 after the rinse is completed, and coal ash is more likely to adhere to it during subsequent use. Therefore, initially, the cleaning plate 8 is located on the left side of the baffle 6, such as Figure 4 As shown, at this time, the hole of the sliding ring 102 is connected to the flow channel 02. When the driving motor 7 drives the cleaning plate 8 to rotate, the cleaning plate 8 also drives the sliding ring 102 to rotate together, so that the cleaning plate 8 and the sliding ring 102 are moved from Figure 4 The state changes to Figure 5 State, the sliding ring 102 rotates to block the flow channel 02, as the cooling fan 101 continues to work, the gas enters the ventilation pipe 11, and is blown onto the surface of the mirror 4 after flushing from the outlet pipe 12, and the residual water on the surface of the mirror 4 is removed in time, and the cleaning plate 8 is set as an arc plate, and the gas blown out of the outlet pipe 12 is guided by the cleaning plate 8 to blow along the surface of the mirror 4, and the residual water on its surface is blown down to the through hole 01 on the left.

[0043] Example 2

[0044] On the basis of Example 1, Figure 7-Figure 9 As shown, the linkage unit includes a linkage ring 51, a movable groove 52, a wedge block 53 and a spring 54; the linkage ring 51 is fixedly connected to the back of the mirror 4; the linkage ring 51 has a plurality of movable grooves 52; the electric slip ring 5 is fixedly connected to a plurality of wedge blocks 53, and the wedge blocks 53 are located at the movable grooves 52; the electric slip ring 5 is fixedly connected to a plurality of springs 54, and the springs 54 are fixedly connected to the linkage ring 51.

[0045] The following are the working steps of the linkage unit:

[0046] In order to make the baffle 6 cooperate with the housing 2 and the upper part of the mirror 4 to maintain a sealed state, prevent the outside coal dust from entering, and avoid water from leaking out during the flushing process, the rib 41 is engaged with the slot 61. However, when the mirror 4 is subsequently driven to rotate and switch, the rib 41 will be stuck in the slot 61, making it difficult to rotate and switch. When the mirror 4 is forced to rotate, the rib 41 is easily squeezed and damaged when the slot 61 is disengaged, and finally the sealing effect between the rib 41 and the slot 61 is reduced; therefore, in the process of the electric slip ring 5 driving the mirror 4 to rotate 180 degrees through the linkage unit, Figure 8 As an example, first control the electric slip ring 5 to rotate 15 degrees clockwise from right to left. Fig. 9 As shown, the electric slip ring 5 drives the wedge block 53 to rotate in the movable groove 52 of the linkage ring 51, and under the action of the wedge block 53, drives the linkage ring 51 to move rightward, the spring 54 is compressed, and the linkage ring 51 drives the mirror 4 to move rightward, so that the rib 41 is separated from the slot 61. At this time, the wedge block 53 clamps the linkage ring 51, and then the electric slip ring 5 is controlled to drive the wedge block 53 and the linkage ring 51 to rotate 180 degrees, and the linkage ring 51 drives the mirror 4 to rotate 180 degrees, so that the mirror 4 rotates and switches, and then the electric slip ring 5 is controlled to rotate counterclockwise from right to left by 15 degrees. The wedge block 53 rotates, the linkage ring 51 loses its limit, and resets under the action of the spring 54, driving the mirror 4 to move to the left again, so that after the rotation switching, the rib 41 and the card slot 61 are re-engaged; in the process of driving the mirror 4 to rotate and switch, the electric slip ring 5 is controlled to first drive the mirror 4 to move, so that the rib 41 and the card slot 61 are separated, and then the mirror 4 is driven to rotate and switch, so that the mirror 4 can be switched stably, ensuring the overall sealing effect, and under the action of the spring 54, the rib 41 and the card slot 61 can also be closely fitted, thereby improving the overall sealing effect.
