[0019] Compared with the prior art, the present invention has the following beneficial effects:

The ventilation copper tube is connected to the monitoring device body, and the bending part at the end is designed to help waterproofing, and the first heat sink aluminum sheet is used to expand the heat dissipation area. The purpose of this design is to improve the heat dissipation efficiency by using the principle of natural convection.

DETAILED DESCRIPTION

[0034] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0035] like Figures 1 to 8 As shown, an embodiment of the present invention provides a mine hydrological dynamic monitoring device.

[0036] The monitoring device body 1 includes a monitoring device body 1, which is connected to a plurality of ventilation copper tubes 2, the ends of the ventilation copper tubes 2 are provided with a bending portion 21, and a plurality of first heat dissipation aluminum fins 22 are penetrated and welded on the bending portion 21. The monitoring device body 1 is connected to a dust cleaning device 4 through a connecting plate 3, the dust cleaning device 4 is connected to a fixing frame 5, the fixing frame 5 is connected to a steering device 6, one side of the steering device 6 is connected to a mounting plate 7, a fin heat sink 8 is fixedly connected to one side of the monitoring device body 1, and a camera 11 and a plurality of sensors 12 are installed on one side of the monitoring device body 1, and the sensor 12 is an infrared monitoring sensor and a temperature and humidity sensor.

[0037] In the mine hydrological dynamic monitoring device, the cleaning of the heat dissipation structure is of vital importance. Traditional cleaning methods often rely on a fixed water spray direction, which makes it difficult to achieve full coverage of heat sinks with complex shapes, especially in places such as mines where there is a lot of dust and a complex environment. Fixed-angle water spraying can easily cause cleaning dead corners and affect heat dissipation efficiency. The present invention introduces the design of two jet nozzles 93, the purpose of which is to ensure all-round and dead-angle-free cleaning of the first heat dissipation aluminum fins 22 and the fin radiator 8 by changing the direction of the water spray from the water spray nozzle 410.

[0038] The conventional water spray nozzle 410 can usually only work at a fixed angle, but the present invention introduces two air jet nozzles 93 and uses the airflow generated by them to interfere with the direction of the water flow sprayed by the water spray nozzle 410. This design allows the water flow to be sprayed at different angles, which not only enhances the flexibility of the cleaning process, but also achieves full coverage of the surface of the heat dissipation structure. For example, when cleaning areas that are difficult to reach due to their location, the additional angle adjustment capability provided by the air jet nozzle 93 is particularly important, avoiding the existence of cleaning dead corners.

[0039] In a mine environment, dust easily adheres to the surface of the heat sink, forming a layer of dirt that is difficult to remove. By changing the water spray angle through two jet nozzles 93, these stubborn dirt can be washed away more effectively. Specifically, when one jet nozzle 93 blows air in one direction, the other jet nozzle 93 can apply pressure from the opposite or side angle, forcing the water flow to flow along a specific path, increasing the impact force, thereby improving the cleaning efficiency. Experimental data shows that compared with single-angle water spraying, multi-angle water spraying can significantly improve the cleaning effect and reduce the number of repeated cleaning times.

[0040] The internal environment of a mine is complex and changeable, and factors such as temperature, humidity, and dust concentration will affect the performance of the heat dissipation system. The design of the jet nozzle 93 in the present invention is particularly suitable for meeting such challenges. It can flexibly adjust the water spray angle according to actual needs to ensure that the cleanliness of the heat dissipation structure can be maintained even under harsh conditions. For example, in a high humidity environment, appropriately adjusting the water spray angle can help prevent secondary contamination caused by residual water; and in a high dust concentration, the cleaning effect can be enhanced by increasing the jet force.

[0041] This design realizes the complete automation of the cleaning process without manual intervention. The gear system driven by the dual motors ensures the precise and reliable movement of the air jet nozzle 93 and the water jet nozzle 410, reducing the maintenance frequency and cost of the equipment. In the long run, this not only saves manpower and material resources, but also improves the operating efficiency and reliability of the entire mine hydrological monitoring system.

[0042] The two jet nozzles 93 can be set to form a specific angle, such as 90 degrees or 120 degrees. This setting allows them to apply airflow from different directions, thereby affecting the flow path of water sprayed by the water spray nozzle 410. Specifically, when the two jet nozzles 93 blow air in opposite or side directions respectively, the cross airflows they generate will guide the water flow along a predetermined trajectory, ensuring that the water flow can cover a wider area and can penetrate into the narrow gaps between the heat sinks. Experimental data shows that compared with single-direction jetting, multi-angle jetting can make the direction of the water flow more flexible and improve the cleaning effect by about 30%.

[0043] By adjusting the angle between the two jet nozzles 93, the distribution range of the water flow sprayed by the water spray nozzle 410 can be effectively changed. For example, at a larger angle, the airflow generated by the jet nozzle 93 will disperse the water flow into a fan shape, thereby expanding the water spray area; while at a smaller angle, the water flow can be concentrated in a narrower area, providing a stronger impact force. This flexibility allows the cleaning process to be optimized according to actual conditions, ensuring effective coverage of a large area of ​​heat dissipation structure and providing local enhanced cleaning when needed.

[0048] The dust cleaning device 4 includes a water pump 42 and a plastic housing 41 . A hose connector 43 is connected to the water inlet of the water pump 42 , and a first connecting pipe 412 is installed on the water outlet of the water pump 42 .

[0049] The first connecting pipe 412 is fixedly connected with an expansion portion 411 , and a water spray nozzle 410 is installed on the expansion portion 411 .

[0050] The outer side of the expansion portion 411 is sleeved with an inner ring plate 48, and the outer side of the inner ring plate 48 is sleeved with an outer ring plate 47. The inner ring plate 48 and the outer ring plate 47 are respectively installed with a jet device 9, and the jet device 9 includes a first connecting seat 91 and a second connecting seat 92. The first connecting seat 91 is fixedly connected to the inner ring plate 48, and the second connecting seat 92 is fixedly connected to the outer ring plate 47. Jet nozzles 93 are respectively installed on the first connecting seat 91 and the second connecting seat 92.

[0051] A first annular gear plate 49 is fixedly connected to the rear of the outer ring plate 47 , a second annular gear plate 413 is fixedly connected to the inner ring plate 48 , a through hole 44 is provided on one side of the plastic housing 41 , and a third gear 415 and a fourth gear 414 are provided inside the plastic housing 41 .

[0052] The third gear 415 is meshed with the first annular gear plate 49, the fourth gear 414 is meshed with the second annular gear plate 413, the inside of the plastic shell 41 is fixedly connected with the first annular baffle 46 and the second annular baffle 45, a connecting column is fixedly connected between the first annular baffle 46 and the second annular baffle 45, the second annular baffle 45 is fixedly connected to the water pump 42, and two second motors are fixedly connected to the outer ring plate 47, and the two second motors are used to drive the fourth gear 414 and the third gear 415 respectively.

[0053] Working principle: First, fix the monitoring device body 1 to a suitable position in the mine through the connecting plate 3, and the four ventilation copper pipes 2 can be ventilated naturally. Then, connect the dust cleaning device 4 to the fixing frame 5, and adjust the position of the mounting plate 7 through the steering device 6 so that the camera 11 and the sensor 12 can cover the target monitoring area.

[0054] The monitoring device body 1 generates heat during operation, which is transferred through a plurality of ventilation copper tubes 2. The first heat sink aluminum sheet 22 welded on the end bend 21 of the ventilation copper tube 2 increases the air contact area, improves the heat dissipation efficiency by natural convection, and ensures that the internal electronic components can still operate stably in a high temperature environment.

[0055] At the same time, the finned heat sink 8 installed on one side of the monitoring device body 1 also participates in the heat dissipation process. The aluminum fins 82 further expand the heat dissipation area, while the copper plate 81 provides an efficient heat conduction path, and the silicone grease layer between the two ensures a good heat transfer effect, thereby effectively dissipating the heat.

[0056] As the equipment runs longer, dust may accumulate on the heat dissipation structure, affecting the heat dissipation effect. At this time, the dust cleaning device 4 starts to work. The water pump 42 draws water through the hose connector 43 and the hose, and delivers it to the expansion part 411 through the first connecting pipe 412, and then the water spray nozzle 410 sprays it evenly to clean the first heat dissipation aluminum sheet 22. In addition, the jet device 9 on the inner ring plate 48 and the outer ring plate 47 will also act synchronously, and the jet nozzle 93 will blow out gas to help remove stubborn dirt and keep the heat dissipation structure clean.

[0057] When the monitoring angle or range needs to be adjusted, the first motor 61 in the steering device 6 drives the second connecting shaft 62 to rotate, driving the two second gears 63 to rotate, thereby changing the angle of the mounting plate 7. This process enables the flexible adjustment of the observation angles of the camera 11 and the sensor 12, ensuring that different monitoring requirements can be met, such as expanding the monitoring range or focusing on a specific area.

[0058] The third gear 415 and the fourth gear 414 in the cleaning device 4 are respectively meshed with the first annular gear plate 49 and the second annular gear plate 413. Driven by the two second motors, the inner ring plate 48 and the outer ring plate 47 rotate, ensuring that the water spray nozzle 410 and the air spray nozzle 93 can clean the heat dissipation structure in all directions without manual intervention.

[0059] The third gear 415 and the fourth gear 414 are arranged inside the dust cleaning device 4, and they are respectively meshed with the first annular gear plate 49 and the second annular gear plate 413. The arrangement of such a gear system ensures the accuracy and stability of power transmission.

[0060] The two second motors are fixedly connected to the outer ring plate 47, one for driving the third gear 415, and the other for driving the fourth gear 414. This enables the inner ring plate 48 and the outer ring plate 47 to rotate independently or synchronously as required, providing the jet device 9 with a full range of operating freedom.

[0061] The jet device 9 on the inner ring plate 48 and the outer ring plate 47 includes a first connection seat 91, a second connection seat 92 and a jet nozzle 93 mounted thereon. When the dual motors are started, the rotation of the two ring plates drives the jet nozzle 93 to make a circular motion around the heat dissipation structure, thereby achieving all-round cleaning of the first heat dissipation aluminum fin 22. The high-pressure gas released by the jet nozzle 93 can effectively remove dust and dirt attached to the heat dissipation fin and maintain the heat dissipation efficiency.

[0062] In addition, the water spray nozzle 410 on the expansion portion 411 also benefits from the rotation mechanism of the inner ring plate 48 and the outer ring plate 47. By adjusting the angle of the water spray nozzle 93, the water flow can change direction as needed and blow to the first heat dissipation aluminum sheet 22 in different directions. This design ensures that the heat dissipation structure can be cleaned without dead angles even in a complex dust environment, thereby enhancing the cleaning effect.

[0063] The purpose of this design is to ensure that the entire cleaning process is fully automated without manual intervention. No matter how harsh the mine environment is, the dust removal device 4 can maintain the cleanliness of the heat dissipation system, reducing maintenance costs and time. At the same time, due to the comprehensive coverage of the cleaning process, work efficiency is improved and the service life of the equipment is effectively extended.

[0064] Finally, through the above mechanism, the present invention achieves the purpose of significantly improving the cleaning effect. The combined use of air jet and water jet, plus the omnidirectional rotation capability, enables each cleaning to completely remove dust accumulation, ensuring that the heat dissipation structure always maintains the best working state, thereby ensuring the long-term stable operation of the mine hydrological dynamic monitoring device.

[0065] In summary, the gear system and dual-motor drive design in the cleaning device 4 not only embodies the high-precision manufacturing process in the field of mechanical engineering, but also demonstrates excellent performance in practical applications, which is of great significance for improving the reliability and efficiency of mine hydrological monitoring work.
