Technical Field

[0001] The utility model relates to the technical field of mine pressure monitoring wireless transmission, in particular to a mine pressure monitoring wireless transmission device for coal mining. Background Art

[0002] During coal mining, mine pressure monitoring devices are installed in the tunnels, and the monitoring data is then transmitted back to the terminal via wireless transmission to facilitate observation of the specific conditions in the tunnels. The underground environment of coal mines is complex and changeable, with harsh conditions such as high temperature, high humidity, and dust. These conditions may have an adverse effect on the performance and stability of the wireless transmission device.

[0003] In the existing technology, water mist is generally used to wet the air in the tunnel to reduce the temperature in the tunnel and avoid an overly high temperature environment. This will cause the moist mineral powder to fall on the wireless transmission device, which in turn causes the wireless transmission device to be covered by the moist mineral powder, easily affecting signal transmission.

[0013] In summary, the present invention has at least one of the following beneficial technical effects:

[0014] 1. This wireless transmission device for coal mine pressure monitoring can dry out wet mineral powder during use, preventing it from smearing on the top of the monitoring box when it is cleaned, thereby forming a covering layer that would affect the signal transmission of the internal wireless signal transmission module. At the same time, it can clean the mineral powder to prevent it from forming a covering layer that affects signal transmission;

[0015] 2. This wireless transmission device for monitoring mine pressure in coal mining drives the motor to rotate, which drives the centrifugal impeller and the rotating shaft to rotate, and then drives the brush roller to rotate counterclockwise, so that the brush roller can clean up semi-dried or fully dry mineral powder. At the same time, the cleaned mineral powder is also transported into the circular groove by the air flow and then blown out through the wind trough. The wind force of the centrifugal impeller can blow the mineral powder directly to the side of the monitoring box, avoiding blocking the wireless signal transmission module and thus blocking the transmission of the signal;

[0017] 4. The hardness of the coal mine pressure monitoring wireless transmission device needs to be harder than that of the brush roller, so that it can scrape off the mineral powder stuck on the top of the monitoring box to prevent it from being too wet and smearing the mineral powder on the monitoring box during cleaning, thereby affecting the signal transmission of the wireless signal transmission module.

DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1-Figure 3The utility model discloses a wireless transmission device for monitoring mine pressure in coal mining, comprising a monitoring box 1, two opposite sides of the monitoring box 1 are connected to positioning rods 2, two sides of the positioning rods 2 away from the monitoring box 1 are slidably connected to sliders 3, a support plate 4 is connected between the tops of the two sliders 3, a cleaning groove 5 is opened in the middle of the bottom side of the support plate 4, and a drying member 6 is provided on the bottom side of the support plate 4;

[0027] The drying element includes an air trough 7, a drive motor 8, a circular groove 9, a disc 10 and a centrifugal impeller 11. The air trough 7 is opened at the top of the support plate 4, the drive motor 8 is fixedly connected to the end of the support plate 4, a circular groove 9 is opened in the support plate 4, and the circular groove 9 is communicated with the cleaning groove 5. The disc 10 is rotatably connected to the side of the circular groove 9 close to the drive motor 8, and the centrifugal impeller 11 is fixedly connected to the side of the disc 10 away from the drive motor 8. A conveying trough 12 is opened in the support plate 4 above the centrifugal impeller 11, and the conveying trough 12 is respectively communicated with the air trough and the circular groove 9, and a cleaning member 13 is provided in the cleaning groove 5.

[0028] In this embodiment, refer to Figure 1 When in use, start the drive motor 8 and move the slider 3 to slide on the positioning rod 2. Figure 3 When the driving motor 8 is started, the disc 10 is driven to rotate, and when the disc 10 rotates, the centrifugal impeller 11 is also driven to rotate. Since the circular groove 9 is connected with the cleaning groove 5, the centrifugal impeller 11 can extract the air in the cleaning groove 5 when it rotates, and transport the air to the conveying groove 12 at the edge of the centrifugal impeller 11, and then transport it to the wind groove 7. Figure 1 , the wind trough 7 will blow the wind toward the monitoring box 1 and the top side, and send away the mineral powder that is about to fall on the top of the monitoring box 1;

[0029] Due to the high temperature in the mine, please refer to Figure 3 , so that the temperature of the air delivered by the centrifugal impeller 11 is the same as the outside temperature, refer to Figure 1 After the airflow is blown to the top side of the monitoring box 1, the wet mineral powder on the top of the monitoring box 1 will be dried by the airflow. However, during the drying process, the mineral powder is only in a semi-dry state to prevent it from being too dry, which may cause the mineral powder to spontaneously combust. The mineral powder can be cleaned by the cleaning component 13. In addition, if the area is continuously sprayed with water mist, the mineral powder can be dried to a completely dry state so that the mineral powder can be blown away directly and the mineral powder can be cleaned conveniently.

[0030] When the support plate 4 moves, refer to Figure 3 The internal cleaning part 13 will move synchronously. After the mineral powder is air-dried to half dry, the cleaning part 13 will clean the mineral powder on the top of the monitoring box 1.

[0031] The wireless signal transmission module in the mine pressure monitoring is installed in the hole on the top of the monitoring box 1 and is sealed to facilitate the cleaning part 13 to clean the wireless signal transmission module, reduce the impact of mineral powder on the transmission module, and avoid wet mineral powder being smeared on the signal transmission module by the cleaning part 13, which is difficult to clean.

[0032] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the bottoms of the two opposite sides of the air duct 7 are inclined and tilted downward in a direction away from the cleaning duct 5 and communicated with the outer side of the support plate 4.

[0033] In this embodiment, refer to Figure 2 The bottom of the air duct 7 is tilted, and the box is tilted downward away from the cleaning trough 5, so that the air duct 7 is set in a five-character shape. Figure 3 After the centrifugal impeller 11 rotates and inputs the wind into the wind trough 7 through the conveying trough 12, refer to Figure 1 , the air flow can be blown smoothly to the top of the monitoring box 1, so as to dry the wet mineral powder.

[0034] In a further preferred embodiment of the present invention, Figure 3-4 As shown, a movable groove 14 is opened on the side of one of the positioning rods 2, and a movable screw 15 is rotatably connected in the movable groove 14. A movable block 16 is threadedly connected to the movable screw 15, and the movable block 16 is connected to the corresponding slider 3. The end of the positioning rod 2 is connected to a movable motor 17.

[0035] In this embodiment, refer to Figure 4 The moving motor 17 can drive the moving screw 15 to rotate, and the moving screw 15 will drive the moving block 16 connected to it by thread to move, thereby driving the slider 3 to move, so as to drive the entire support plate 4 to move, refer to Figure 3 , so as to drive the entire cleaning component 13 and the drying component 6 to move, thereby facilitating the cleaning of the mineral powder on the monitoring box 1.

[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, the cleaning member 13 includes a rotating shaft 18, which is fixedly connected to the center of one side of the disc 10 close to the cleaning groove 5. The end of the rotating shaft 18 extends into the cleaning groove 5 and is connected to a brush roller 19.

[0037] In this embodiment, refer to Figure 3The driving motor 8 rotates, driving the centrifugal impeller 11 while also driving the rotating shaft 18 to rotate, and then driving the brush roller to rotate counterclockwise, so that the brush roller can clean the semi-dried or fully dry mineral powder. At the same time, the cleaned mineral powder will also be transported to the circular groove 9 with the air flow, and then blown out through the wind groove 7. The wind force of the centrifugal impeller 11 can blow the mineral powder directly to the side of the monitoring box 1, avoiding blocking the wireless signal transmission module, thereby blocking the signal transmission.

[0038] In a further preferred embodiment of the present invention, Figure 3 As shown, a gear 20 is rotatably connected to one end of the support plate 4 away from the drive motor 8, and a gear 21 is engaged with the side of the gear 20. The gear 21 is rotatably connected in the support plate 4, and a brush roller 22 is rotatably connected in the cleaning tank 5. The gear 20 is connected to the brush roller 19, and the gear 21 is connected to the brush roller 22.

[0039] In this embodiment, refer to Figure 3 The rotation of the brush roller 19 will drive the gear 1 20 to rotate, and the rotation of the gear 1 20 will drive the gear 2 21 meshing with it to rotate. When the gear 2 21 rotates, it will also drive the brush roller 2 22 to rotate, so that when the support plate 4 moves back and forth, the corresponding cleaning work can be carried out to prevent the mineral powder from accumulating in the cleaning tank 5, which will cause the mineral powder to fall again on the top of the monitoring box 1 during subsequent cleaning.

[0040] In a further preferred embodiment of the present invention, Figure 2 As shown, auxiliary brushes 23 are connected to two opposite sides of the bottom of the support plate 4 , and the bottom of the auxiliary brush 23 is in contact with the top side wall of the monitoring box 1 .

[0041] In this embodiment, refer to Figure 2 Its hardness needs to be harder than that of the brush roller 19, so that it can scrape off the mineral powder stuck on the top of the monitoring box 1 to avoid it being too wet and causing the mineral powder to be smeared on the monitoring box 1 during cleaning, thereby affecting the signal transmission of the wireless signal transmission module.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
