Description

Technical Field

[0001] This invention belongs to the field of intelligent dust suppression and cooling technology, specifically a full-section intelligent spray dust suppression and cooling system and method. Background Technology

[0002] In deep mining operations, the increasingly severe problems of high-temperature environments and high-concentration dust pollution pose significant challenges to miners' health and safety. High temperatures not only reduce worker efficiency but can also trigger safety accidents such as gas explosions and spontaneous combustion of coal, while high-concentration dust can lead to pneumoconiosis in workers, damage to machinery, and even mine fires. Currently, mine spray cooling and dust suppression technology is the most commonly used method. However, most existing technologies use fixed spray devices or manually adjustable spray trolleys, which suffer from uneven spray coverage, poor equipment flexibility, cumbersome manual operation, and high maintenance costs, making it difficult to meet the high-efficiency management needs of the complex environment in deep mines.

[0003] To address the aforementioned issues, intelligent spraying systems have become a research hotspot in recent years. Currently, some systems integrate sensor monitoring and automated control technologies, automatically adjusting the spray volume and angle based on dust concentration and temperature changes within the mine, thereby improving dust suppression and cooling effects. However, existing intelligent spraying equipment still suffers from limitations such as complex installation, high cost, and difficulty in achieving full-section coverage, particularly in complex mine roadways where blind spots remain a serious problem. Therefore, there is an urgent need for a new type of intelligent spraying dust suppression and cooling system that can achieve full-section coverage, intelligent control, and low installation and maintenance costs to meet the actual needs of different mines. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a full-section intelligent spray dust suppression and cooling system and method. This system has a simple structure, low manufacturing cost, and can achieve full-section coverage of the roadway. It can simultaneously perform spray dust suppression and cooling operations across the entire roadway section, effectively solving problems such as incomplete coverage, untimely response, and cumbersome manual adjustments in existing high-temperature, high-dust mining environments. It can meet the high-efficiency management needs of complex environments in deep mines. The method is simple to implement and highly intelligent, enabling coordinated operation of full-section spraying and efficient cooling and dust suppression, and achieving on-demand, targeted, and efficient spray dust suppression and cooling control.

[0005] To achieve the above objectives, the present invention provides a full-section intelligent spray dust suppression and cooling system, including a support platform, a spray cooling and dust suppression execution unit, an intelligent sensing unit, a power supply unit, and an intelligent control unit. The spray cooling and dust suppression unit is installed at the rear of the support platform. The unit includes a water tank, a cooling device, a high-pressure pump set, and a spray pipe network. The cooling device is connected to the water tank and is used to cool the liquid in the tank. The inlet of the high-pressure pump set is connected to the outlet of the water tank. The spray pipe network includes a spray bracket, nozzles, and a water supply network. The outer contour of the spray bracket is arc-shaped, and multiple nozzles are circumferentially spaced on the spray bracket. The inlet of the water supply network is connected to the outlet of the high-pressure pump set, and its multiple outlets are respectively connected to multiple nozzles. The intelligent sensing unit is installed on the support platform and is used to sense temperature, humidity and dust concentration data in the environment. The power supply unit is installed on the support platform and is used to supply energy to the various components; The intelligent control unit is installed on the support platform and is connected to the intelligent sensing unit, the spray cooling and dust suppression execution unit, and the power supply unit, respectively.

[0006] In this invention, the cooling device cools the liquid in the water tank, thereby lowering the temperature of the spray. This allows for simultaneous dust suppression and ambient temperature reduction, achieving a synchronized dust suppression and cooling effect. The spray support has an arc-shaped outer contour, and multiple nozzles are circumferentially spaced on it. The arc-shaped contour of the support allows the nozzles to be positioned closer to the tunnel roof and sides, enabling simultaneous spraying of the entire tunnel surface. The intelligent sensing unit facilitates real-time collection of temperature, humidity, and dust concentration data at the work location. This allows for dynamic adjustment of the number and number of nozzles performing the spray operation based on these data, as well as dynamic adjustment of the spray angle and volume, improving the effectiveness and efficiency of dust suppression and cooling. The intelligent control unit enables intelligent control of the dust suppression and cooling operation.

[0007] The system has a simple structure and low manufacturing cost, and can achieve full cross-section coverage of the roadway. It can carry out synchronous spraying dust suppression and cooling operations on the entire cross-section of the roadway. It can effectively solve the problems of incomplete coverage, untimely response, and cumbersome manual adjustment of existing spraying systems in high-temperature and high-dust working environments in mines, and meet the needs of efficient management of complex environments in deep mines.

[0008] Furthermore, to facilitate the slidable mounting of multiple nozzles around the spray bracket, allowing them to be supported in an arc shape, thus better adapting to the spray coverage requirements of the entire tunnel cross-section, and to facilitate convenient repositioning of the nozzles within the annular grooves on the spray bracket to adapt to different working conditions, an annular groove is formed on the outer circumferential surface of the spray bracket, and multiple connecting holes are spaced circumferentially on its inner circumferential surface; the nozzles are electrically powered universal nozzles, with universal ball joints at their water inlet ends, and these universal ball joints are slidably mounted within the annular grooves; the water supply network includes a main... The system includes drainage pipes, auxiliary drainage pipes, branch drainage pipes, solenoid valves, and connecting hoses. The inlet of the main drainage pipe is connected to the outlet of the high-pressure pump unit. The inlets of multiple auxiliary drainage pipes are connected to the outlets of the main drainage pipe via pipe connectors. The branch drainage pipes are Y-shaped, each with one inlet and two outlets. The inlets of multiple branch drainage pipes are connected to the outlets of multiple auxiliary drainage pipes, and the inlets of multiple connecting hoses are connected to the outlets of multiple branch drainage pipes via multiple solenoid valves. The outlets of the hoses pass through multiple connecting holes into annular grooves and are connected to the universal ball joints of multiple nozzles. The Y-shaped branch drainage pipes facilitate water supply to two adjacent nozzles using a single branch drainage pipe, simplifying the water supply network structure. Furthermore, the Y-shaped water distribution method reduces resistance during water supply.

[0009] Furthermore, in order to enable the full-section intelligent spray dust suppression and cooling system to move flexibly within the working tunnel and effectively adapt to the tunnel's driving environment, the support platform is a mobile support platform, which includes a carriage, a chassis installed at the bottom of the carriage, a drive motor installed at the bottom of the chassis, and two track mechanisms located on the outer sides of both ends of the carriage; the drive motor is connected to the intelligent control unit; the track mechanism includes a drive wheel, a tension wheel, a support roller, and track plates; the drive wheel and the tension wheel are rotatably installed at both ends of the chassis in the length direction, and the drive wheel is connected to the drive motor; multiple support rollers are distributed at intervals between the drive wheel and the tension wheel, and are rotatably connected to the middle section of the chassis; multiple track plates are connected in sequence to form a ring, and are wound around and connected to the outside of the drive wheel, multiple support rollers, and the tension wheel. By installing two tracked mechanisms on the outside of the carriage on the support platform and assembling a drive motor on the platform's chassis, the tracked mechanisms can be used to drive the support platform to move within the roadway, forming a trolley-type mobile platform. This improves the system's mobility and adaptability to roadway cross-sections. This trolley-type mobile platform, equipped with an arc-shaped spray support structure and an intelligent spray execution module, combined with real-time sensor monitoring and intelligent control technology, allows the spray system to automatically adjust the spray range and intensity according to changes in the mine environment. Furthermore, this innovative combination integrates the annular grooved slide rail and spray support onto a mobile support platform, avoiding costly fixed installation in the roadway, significantly reducing manual labor, and improving the system's applicability and economy. This provides a more intelligent, efficient, and low-cost solution for safe mine production.

[0010] As a preferred embodiment, the high-pressure pump set includes a centrifugal pump, a motor, and a main solenoid valve; the motor is coaxially connected to the centrifugal pump; the main solenoid valve is connected to the water inlet of the centrifugal pump and is used to control the opening and closing of the water inlet channel; in order to enable the system to operate offline and to facilitate the charging of the battery pack, the power supply unit includes a battery pack and a charging interface. The charging interface is set on the support platform and connected to the battery pack for connecting to the power supply of the mine power supply system to charge the battery pack.

[0011] Furthermore, to simplify the overall structure of the intelligent sensing unit and to effectively sense environmental temperature, humidity, and dust concentration data, the intelligent sensing unit includes a probe bracket, a temperature sensor, a humidity sensor, and a dust concentration sensor. The lower end of the probe bracket is mounted on the top of the front end of the water tank, and its upper end extends to the outer side of the front end of the support platform. The temperature sensor, humidity sensor, and dust concentration sensor are spaced apart and mounted on the upper end of the probe bracket. Extending the probe bracket to the outer side of the front end of the support platform allows for more effective sensing of temperature, humidity, and dust concentration data in the working environment. This avoids the adverse effects of differences in temperature, humidity, and dust concentration on the support platform on the environmental temperature, humidity, and dust concentration, ensuring measurement accuracy.

[0012] As a preferred embodiment, the cooling device includes a spiral copper tube, a refrigeration assembly, and a refrigerant storage tank; The spiral copper tube extends in a spiral shape and is disposed within the inner cavity of the water tank. The refrigeration assembly is installed at the upper end of the water tank and includes a compressor, a condenser, and a throttling valve. The inlet of the compressor is connected to one end of the spiral copper tube, the inlet of the condenser is connected to the outlet of the compressor, and the outlet of the throttling valve is connected to the other end of the spiral copper tube. The inlet of the refrigerant storage tank is connected to the outlet of the condenser via a connecting pipe, and its outlet is connected to the inlet of the throttling valve via a connecting pipe. This connection method allows the refrigerant to circulate through the spiral copper tube, and through the combined action of the compressor, condenser, and throttling valve, the refrigerant flowing into the spiral copper tube is kept at a low temperature. This allows for heat exchange to cool the liquid in the water tank. In this way, it can work in conjunction with the spray pipe network to form an integrated mist-cooling coupling cooling effect, thereby achieving more efficient cooling while simultaneously suppressing dust.

[0013] Furthermore, to enhance the system's intelligence, a second intelligent sensing unit is included. This unit comprises a top distance sensor, side distance sensors, a water level sensor, a pressure gauge, and a radar detection module. The top distance sensor is installed on one side of the top of the spray support, while the two side distance sensors are installed opposite each other on one side of the spray support's width direction. The water level sensor is installed in the water tank to collect the liquid level signal inside the tank in real time. The pressure gauge is connected to the outlet of the centrifugal pump to collect the pressure signal of the water outlet channel in real time. Multiple radar detection modules are installed around the support platform to collect surrounding obstacle signals in real time. The second intelligent sensing unit is connected to the intelligent control unit. The top and side distance sensors facilitate real-time sensing of the distance data from the top nozzle to the tunnel roof (data 1) and the distance data from the side nozzles to the tunnel walls (data 2). This allows the system to adaptively adjust the angle and spray volume of each nozzle according to changes in the tunnel's height and width, effectively adapting to the heterogeneity of ventilation, heat hazard, and dust distribution across different cross-sections, thus achieving "on-demand spraying" operation requirements. By configuring a water level sensor, the system can monitor the water level in the tank in real time during spraying operations. This allows for timely alarms when the water level falls below a set value, alerting personnel to replenish the water supply. Similarly, a pressure gauge can collect real-time pressure data from the centrifugal pump outlet during high-pressure pump operation. Abnormal pressure readings trigger alarms, prompting timely maintenance of the high-pressure pump unit. Multiple radar detection modules facilitate automatic positioning and path planning, enabling autonomous driving and obstacle avoidance during operation, significantly enhancing the system's flexibility and intelligence.

[0014] Furthermore, to facilitate wireless communication with the outside world and to provide timely warnings in case of anomalies, the intelligent control unit includes a controller, an alarm, and a wireless communication module. The alarm is installed on the water tank to perform alarm actions. The wireless communication module is installed on the water tank to establish a wireless communication connection between the intelligent control unit and external devices. The controller is installed on the water tank and is connected to both the alarm and the radar detection module.

[0015] This invention is based on a modular tracked mobile platform, which is compact, highly mobile, flexible, and intelligent. It is suitable for use in mine environments with narrow tunnels and complex terrain. The entire system can complete a closed-loop control process of "perception-decision-execution" without human intervention, supporting long-term stable operation underground and reducing the labor intensity and safety risks for workers. Furthermore, by incorporating an arc-shaped spray frame, adjustable nozzles, and multi-parameter environmental sensors, this system can automatically adjust the spray mode and parameters based on operating conditions such as temperature and dust concentration within the tunnel, achieving on-demand, directional, and efficient spray control. The spray system also employs a multi-level branch network design, with each branch connecting to an independently controlled atomizing nozzle controlled by a solenoid valve. The nozzle is driven by a built-in servo motor and secured in a movable annular groove via a universal ball joint. This structure not only enables three-dimensional adjustment of the nozzle angle but also supports movement along a track on the spray support. Combined with temperature, humidity, dust concentration, and distance data collected by the intelligent sensing unit, it allows for precise control of atomization direction, position, and flow rate. Compared to existing fixed-angle spraying equipment, this invention significantly improves droplet coverage and spraying efficiency, avoiding resource waste. Simultaneously, the system features self-driving or cooperative movement capabilities, adapting to different tunnel cross-sections and work rhythms, avoiding repeated spraying and energy waste, significantly improving the utilization efficiency of the spray fluid, reducing water and energy consumption, and ensuring the safety and comfort of operators. The system's overall structure is flexible to install, suitable for various mine tunnel environments, provides ideal cooling and dust suppression effects, has a high level of intelligence, and has promising prospects for widespread application.

[0016] This invention also provides a full-section intelligent spray dust suppression and cooling method, which employs a full-section intelligent spray dust suppression and cooling system, including the following steps: Step 1: Preparation for Operation; The full-section intelligent spray dust suppression and cooling system was placed in the roadway to be operated, and its various functions were tested. Step 2: Start the spray cooling and dust suppression operation; S21: The controller obtains temperature, humidity, and dust concentration data in the current working environment through temperature, humidity, and dust concentration sensors. It obtains the distance data 1 between the top of the spray support and the roof of the tunnel through the top distance sensor, and the distance data 2 between the side of the spray support and the side wall of the tunnel through the side distance sensor. It obtains the surrounding obstacle situation through multiple radar detection modules, and selects the number and number of nozzles to be activated based on the temperature, humidity, and dust concentration data in the current working environment. It determines the spray volume and atomization direction of the selected nozzles based on distance data 1 and distance data 2, and plans the travel path based on the surrounding obstacle situation. S22: The controller controls the drive motor to start working, so that the track mechanism drives the support platform to move along the preset path. The controller controls the main solenoid valve to open, controls the motor to drive the centrifugal pump to start working, controls the angle of the selected nozzle to rotate to the atomization direction, controls the solenoid valve corresponding to the selected nozzle to open, and controls the valve opening degree of the opened solenoid valve to make the spray volume of the nozzle reach the required spray volume for full-section spray dust suppression operation. Simultaneously, the real-time temperature data is compared with the preset temperature threshold. When the temperature data is higher than the preset temperature threshold, the cooling device is activated to cool the water in the tank and reduce the ambient temperature using spray. The cooling device stops working when the temperature data is no higher than the preset temperature threshold, thus performing a comprehensive spray dust suppression and cooling operation. The number and number of nozzles to be activated are adjusted based on the real-time temperature, humidity, and dust concentration data of the current working environment. The spray volume and atomization direction of the nozzles to be activated are adjusted based on the real-time distance data 1 and distance data 2. At the same time, the travel path is dynamically adjusted based on real-time feedback of surrounding obstacles; Simultaneously, the system obtains pressure data from the centrifugal pump outlet channel using a pressure gauge, and liquid level data from the water tank using a water level sensor. The system compares the pressure data with the set pressure range and the liquid level data with the set liquid level threshold. If the pressure data exceeds the predetermined pressure range or the liquid level data falls below the set liquid level threshold, the system determines that an abnormal operating condition is in effect and activates the alarm. At the same time, the system stops the drive motor, closes the main solenoid valve, stops the motor, and closes the solenoid valve until the abnormal operating condition disappears, at which point the system returns to its previous operating condition.

[0017] Furthermore, in order to utilize multiple full-section intelligent spray dust suppression and cooling systems to simultaneously spray and cover the entire cross-section of the roadway, thereby achieving more efficient dust suppression and cooling operations, in step two, when multiple full-section intelligent spray dust suppression and cooling systems are simultaneously deployed in the working roadway, one full-section intelligent spray dust suppression and cooling system is designated as the master system, and the remaining multiple full-section intelligent spray dust suppression and cooling systems are designated as slave systems. The master system and the multiple slave systems are connected wirelessly. When the master system and the multiple slave systems are simultaneously performing spray dust suppression and cooling operations, the multiple slave systems will control the temperature at their respective locations. Temperature, humidity, and dust concentration data are sent to the main system. The controller in the main system sends corresponding work interval data to each slave system based on the temperature, humidity, and dust concentration data at the location of the main and slave systems. Each slave system adjusts the spacing between adjacent full-section intelligent spray dust suppression and cooling systems according to the work interval data. This allows for real-time adjustment of the spacing between multiple full-section intelligent spray dust suppression and cooling systems based on changes in temperature, humidity, and dust concentration in different areas of the roadway, achieving coordinated and interconnected full-section spray dust suppression and cooling coverage. Through intelligent linkage control between multiple systems, the controllers built into each system can exchange information wirelessly, automatically adjusting their spacing according to differences in the local environment, achieving adaptive layout and regional collaborative operation. This linkage mechanism can dynamically plan the spray route and coverage area based on the shape of the roadway cross-section and changes in the intensity of heat hazard, ensuring no blind spots in cooling and dust suppression coverage, thus meeting the actual needs of "full-section" intelligent spray operations underground.

[0018] This patent proposes a full-section intelligent spray dust suppression and cooling method, aiming to achieve full-section spray coverage in mine roadways and improve dust suppression and cooling efficiency. During operation, the cooling module and high-pressure water mist work together to achieve dual-effect dust suppression and cooling in the mine environment, significantly improving operational efficiency and greatly enhancing the dust suppression and cooling effect. This method effectively reduces blind spots in spray operations and better adapts to the heterogeneity of ventilation, heat hazards, and dust distribution in different sections, enabling "on-demand spraying." Simultaneously, the spray combined with the cooling function of the cooling module forms a "mist-cold coupling," enhancing cooling intensity and improving the thermal environment of the work area, thus improving worker comfort. During operation, the spray flow rate and angle are intelligently adjusted based on temperature, humidity, and dust concentration data, enabling variable spray arrangements within the vehicle's width and height range, providing extremely strong full-section coverage capability. Compared with existing technologies, this invention provides a full-section spray intelligent dust suppression and cooling system that can operate autonomously and adjust intelligently in complex mine environments, achieving several technological breakthroughs such as directional controllable spraying, coordinated linkage of multiple systems, and real-time environmental perception and response control.

[0019] This method is simple to implement and highly intelligent. It can achieve coordinated operation of full-section spraying and efficient cooling and dust suppression. It can also achieve on-demand, targeted, and efficient spraying dust suppression and cooling control, and can effectively solve the problems of incomplete coverage, untimely response, and cumbersome manual adjustment of existing spraying systems in high-temperature and high-dust working environments in mines.

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] like Figures 1 to 8 As shown, the present invention provides a full-section intelligent spray dust suppression and cooling system, including a support platform 1, a spray cooling and dust suppression execution unit 2, an intelligent sensing unit 3, a power supply unit 4, and an intelligent control unit 5; The spray cooling and dust suppression execution unit 2 is installed at the rear of the support platform 1. The spray cooling and dust suppression execution unit 2 includes a water tank 6, a cooling device 7, a high-pressure pump set 8, and a spray pipe network. The cooling device 7 is connected to the water tank 6 and is used to cool the liquid in the water tank 6. The inlet of the high-pressure pump set 8 is connected to the outlet 9 of the water tank 6. The spray pipe network includes a spray bracket 10, nozzles 11, and a water supply pipe network 12. The outer contour of the spray bracket 10 is arc-shaped, which can be adapted to the contour of the tunnel cross-section, thereby facilitating the full-section spray dust suppression and cooling operation. Multiple nozzles 11 are circumferentially spaced on the spray bracket 10. The inlet of the water supply pipe network 12 is connected to the outlet of the high-pressure pump set 8, and its multiple outlets are respectively connected to multiple nozzles 11. The intelligent sensing unit 3 is installed on the support platform 1 and is used to sense temperature, humidity and dust concentration data in the environment. The power supply unit 4 is installed on the support platform 1 and is used to supply energy to each component; The intelligent control unit 5 is installed on the support platform 1 and is connected to the intelligent sensing unit 3, the spray cooling and dust suppression execution unit 2, and the power supply unit 4, respectively.

[0024] In this invention, the cooling device cools the liquid in the water tank, thereby lowering the temperature of the spray. This allows for simultaneous dust suppression and ambient temperature reduction, achieving a synchronized dust suppression and cooling effect. The spray support has an arc-shaped outer contour, and multiple nozzles are circumferentially spaced on it. The arc-shaped contour of the support allows the nozzles to be positioned closer to the tunnel roof and sides, enabling simultaneous spraying of the entire tunnel surface. The intelligent sensing unit facilitates real-time collection of temperature, humidity, and dust concentration data at the work location. This allows for dynamic adjustment of the number and number of nozzles performing the spray operation based on these data, as well as dynamic adjustment of the spray angle and volume, improving the effectiveness and efficiency of dust suppression and cooling. The intelligent control unit enables intelligent control of the dust suppression and cooling operation.

[0025] The system has a simple structure and low manufacturing cost, and can achieve full-section coverage of the roadway. It can carry out synchronous spraying dust suppression and cooling operations on the entire roadway section. It can effectively solve the problems of incomplete coverage, untimely response, and cumbersome manual adjustment of existing spraying systems in high-temperature and high-dust working environments in mines, and meet the needs of efficient management of complex environments in deep mines.

[0026] To facilitate the slidable mounting of multiple nozzles around the spray bracket, allowing them to be supported in an arc shape, thus better meeting the spray coverage requirements of the entire tunnel cross-section, and to facilitate convenient repositioning of the nozzles within the annular grooves on the spray bracket to adapt to different working conditions, the outer surface of the spray bracket 10 has an annular groove 18, and its inner surface has multiple circumferentially spaced connecting holes 19. The nozzle 11 is an electrically operated universal nozzle, with a universal ball joint 20 at its water inlet end, and the universal ball joint 20 is slidably mounted in the annular groove 18. In step 8, the nozzle 11 can be adjusted by using its built-in servo motor. The preferred adjustment range is ±45° horizontally and ±60° vertically. In this way, the nozzle 11 can be freely adjusted in position within the circumferential range of the spray bracket 11. At the same time, its spray angle can be adjusted at multiple angles, enabling different directional spray operations on different cross sections. More preferably, multiple nozzles 11 can be evenly distributed on the spray bracket 10. At the same time, the position of each nozzle 11 on the spray bracket 10 can be adjusted according to different operating conditions to achieve a variable spray arrangement within the overall width range of the system.

[0027] The water supply network 12 includes a main drainage pipe 13, an auxiliary drainage pipe 14, branch drainage pipes 15, solenoid valves 17, and connecting hoses 16. The inlet end of the main drainage pipe 13 is connected to the outlet end of the high-pressure pump set 8. The inlets of multiple auxiliary drainage pipes 14 are connected to the outlet ends of the main drainage pipe 13 through pipe connectors. The branch drainage pipes 15 are Y-shaped, with one inlet end and two outlet ends. The inlets of multiple branch drainage pipes 15 are respectively connected to the outlet ends of multiple auxiliary drainage pipes 14. The inlets of multiple connecting hoses 16 are respectively connected to the outlet ends of multiple branch drainage pipes 15 through multiple solenoid valves 17. Their outlet ends pass through multiple connecting holes 19 into an annular groove 18 and are respectively connected to the universal ball joints 20 of multiple nozzles 11. For each solenoid valve 17, the intelligent control unit 5 can independently control its opening and closing time, and simultaneously control the opening degree of its valve port to effectively regulate the liquid flow rate and velocity entering the corresponding nozzle 11, thereby achieving the regulation of the spray volume. Preferably, the intelligent control unit 5 can comprehensively determine which solenoid valve 17 needs to be opened based on the temperature, humidity, and dust concentration data of the current working environment, thus selectively enabling multiple specific nozzles 11 to perform spray dust suppression and cooling operations. In addition, the intelligent control unit 5 can also intelligently adjust the angle of the nozzles 11 to effectively regulate the atomization direction, further improving the spray dust suppression and cooling effect, and achieving automatic spray direction orientation. The universal ball joint 20 can be slidably installed in the annular groove 18, so that the position of multiple nozzles 11 on the spray bracket 10 can be adjusted according to the actual conditions of the tunnel to adapt to different operational needs, thereby improving the flexibility of adjustment. By using multiple branch drainage pipes in a Y-shape, it is convenient to use one branch drainage pipe to supply water to two adjacent nozzles, which can simplify the structure of the water supply network. At the same time, the Y-shaped water supply method can reduce the resistance in the water supply process.

[0028] As a preferred embodiment, the spray bracket 10 is an overall ring shape with an open bottom, wherein the open bottom portion is welded to the top of the rear end of the water tank 6. More preferably, it is in the shape of a 320° arc with a radius of 750 mm to effectively support multiple nozzles 11 to cover the entire cross-section of the tunnel. To enable the full-section intelligent spray dust suppression and cooling system to move flexibly within the working tunnel and effectively adapt to the tunnel's driving environment, the support platform 1 is a mobile support platform, comprising a carriage 21, a chassis 22 mounted at the bottom of the carriage 21, a drive motor mounted at the bottom of the chassis 22, and two track mechanisms 23 located on the outer sides of both ends of the carriage 21. The drive motor is connected to the intelligent control unit 5. The track mechanism 23 includes a drive wheel 24, a tension wheel 25, a support roller 26, and track plates 27.

Multiple support rollers 26 are spaced apart between the drive wheel 24 and the tension wheel 25 and are rotatably connected to the middle section of the chassis 22. Multiple track plates 27 are sequentially connected to form a ring and are wound around the outside of the drive wheel 24, the multiple support rollers 26, and the tension wheel 25. The track mechanism 23 drives the carriage 21 to move within the mine roadway. The tension wheel 25, in conjunction with multiple support rollers 26 and drive wheels 24, supports multiple interconnected track plates 27 to maintain stability. Simultaneously, the drive wheels 24 drive the track plates 27 to rotate, thus moving the carriage 21 within the working environment. A water tank 6 is installed on the top of the carriage 21, and its top is equipped with a water inlet 40 for water replenishment. Preferably, water can be replenished directly from a water pipe within the roadway. Preferably, the height of the spray bracket 10 is greater than the height of the carriage 21, and its width is greater than the width of the carriage 21. By installing two track mechanisms on the outside of the carriage on the support platform and assembling a drive motor on the chassis of the support platform, the track mechanism can be used to drive the support platform to move within the roadway, improving the system's mobility and adaptability to roadway cross-sections. This trolley-style mobile platform, equipped with an arc-shaped spray support structure and an intelligent spray execution module, combined with real-time sensor monitoring and intelligent control technology, enables the spray system to automatically adjust the spray range and intensity according to changes in the mine environment. Furthermore, this innovative combination integrates the annular grooved slide rail and spray support onto a mobile support platform, avoiding costly fixed installation in roadways, significantly reducing manual labor, and improving the system's applicability and economy. This provides a more intelligent, efficient, and low-cost solution for safe mine production.

[0029] As a preferred embodiment, the chassis 22 is a frame structure with a cubic outer contour, used to support the various components; Preferably, the high-pressure pump unit 8 includes a centrifugal pump 28, a motor 29, and a main solenoid valve 31; the motor 29 is coaxially connected to the centrifugal pump 28; the main solenoid valve 31 is connected to the water inlet of the centrifugal pump 28 and is used to control the opening and closing of the water inlet channel; to enable the system to operate offline and to facilitate the charging of the battery pack, the power supply unit 4 includes a battery pack 32 and a charging interface.

Further preferably, the charging interface is compatible with both direct underground power supply and independent power supply modes, avoiding the safety hazards caused by the additional wiring required for traditional devices and improving the application safety of the system in high-risk areas such as gas explosion zones.

[0030] To simplify the overall structure of the intelligent sensing unit 1 and to effectively sense temperature, humidity, and dust concentration data in the environment, the intelligent sensing unit 1 3 includes a probe bracket 33, a temperature sensor 34, a humidity sensor 35, and a dust concentration sensor 36. The lower end of the probe bracket 33 is mounted on the top of the front end of the water tank 6, and its upper end extends to the outer side of the front end of the support platform 1. The temperature sensor 34, humidity sensor 35, and dust concentration sensor 36 are installed alternately on the upper end of the probe bracket 33. The temperature sensor 34, humidity sensor 35, and dust concentration sensor 36 are used to collect temperature, humidity, and dust concentration signals in the current working environment, respectively, and send them to the controller in the intelligent control unit 5. The controller obtains the temperature, humidity, and dust concentration data of the current working environment based on these signals. Extending the probe bracket to the outer side of the front end of the support platform allows for more effective sensing of temperature, humidity, and dust concentration data in the working environment. This avoids the adverse effects of differences in temperature, humidity, and dust concentration on the support platform on the temperature, humidity, and dust concentration in the environment, ensuring measurement accuracy.

[0031] As a preferred embodiment, the cooling device 7 includes a spiral copper tube 37, a refrigeration component 38, and a refrigerant storage tank 39; The spiral copper tube 37 extends in a spiral shape and is disposed within the inner cavity of the water tank 6.

The inlet of the compressor is connected to one end of the spiral copper tube 37, the inlet of the condenser is connected to the outlet of the compressor, and the outlet of the throttling valve is connected to the other end of the spiral copper tube 37. The inlet of the refrigerant storage tank 39 is connected to the outlet of the condenser via a connecting pipe one, and its outlet is connected to the inlet of the throttling valve via a connecting pipe two. Preferably, the refrigerant storage tank 39 stores R1234yf refrigerant. This connection method allows the refrigerant to circulate through the spiral copper tube, and through the combined action of the compressor, condenser, and throttling valve, the refrigerant flowing into the spiral copper tube is kept at a low temperature. This allows for heat exchange to cool the liquid in the water tank. In this way, it can work in conjunction with the spray pipe network to form an integrated spray-heat exchange mist-cooling coupling cooling effect, thereby achieving cooling more efficiently while spraying dust suppression.

[0032] To enhance the system's intelligence, a second intelligent sensing unit is also included. This second intelligent sensing unit comprises a top ranging sensor 42, two side ranging sensors 43, a water level sensor 41, a pressure gauge 30, and a radar detection module. The top ranging sensor 42 is installed on one side of the top of the spray support 10, and the two side ranging sensors 43 are installed opposite each other on one side of the two ends of the spray support 10 in the width direction. The water level sensor 41 is installed in the water tank 6 to collect the liquid level signal inside the water tank 6 in real time. The pressure gauge 30 is connected to the outlet of the centrifugal pump 28 to collect the pressure signal of the water outlet channel in real time. Multiple radar detection modules are installed around the support platform 1 to collect the surrounding obstacle signals in real time. The second intelligent sensing unit is connected to the intelligent control unit 5. Among them, the top distance sensor 42 is used to collect the distance signal 1 between the top of the spray support 10 and the tunnel roof, and send it to the controller in the intelligent control unit 5. The controller obtains the distance data 1 between the top of the spray support 10 and the tunnel roof based on the distance signal 1. The side distance sensor 43 is used to collect the distance signal 2 between the two sides of the spray support 10 and the tunnel sidewall, and send it to the controller in the intelligent control unit 5. The controller obtains the distance data 2 between the side of the spray support 10 and the tunnel sidewall based on the distance signal 2. The water level sensor 41 is used to collect the liquid level signal in the water tank 6 and send it to the controller in the intelligent control unit 5. The controller obtains the liquid level height data in the water tank 6 based on the liquid level signal. In this way, the liquid level height inside the water tank 6 can be detected in time. When the liquid level height does not meet the operation requirements, Water replenishment can be carried out in a timely manner through warning, which can effectively prevent the centrifugal pump 28 from running dry and being damaged. The pressure gauge 30 is used to collect the pressure signal of the water outlet channel of the centrifugal pump 28 and send it to the controller in the intelligent control unit 5. The controller obtains the pressure data of the water outlet channel based on the pressure signal. Multiple radar detection modules are used to collect obstacle signals around the support platform 1 and send them to the controller in the intelligent control unit 5. The controller obtains the obstacle situation around the support platform 1 based on the surrounding obstacle signals. Furthermore, the controller can also perform three-dimensional modeling and obstacle recognition based on the detection data of the radar detection modules. This makes it easier for the controller to perform better path planning, so that the support platform 1 can achieve intelligent movement and obstacle avoidance in the mine, improving the level of intelligence of movement.

[0033] To facilitate wireless communication with the outside world and to provide timely warnings in case of anomalies, the intelligent control unit 5 includes a controller, an alarm, and a wireless communication module. The alarm is installed on the water tank 6 to perform alarm actions. The wireless communication module is installed on the water tank 6 to establish a wireless communication connection between the intelligent control unit 5 and external devices. The controller is installed on the water tank 6 and is connected to both the alarm and the radar detection module.

[0034] This invention is based on a modular tracked mobile platform, which is compact, highly mobile, flexible, and intelligent. It is suitable for use in mine environments with narrow tunnels and complex terrain. The entire system can complete a closed-loop control process of "perception-decision-execution" without human intervention, supporting long-term stable operation underground and reducing the labor intensity and safety risks for workers. Furthermore, by incorporating an arc-shaped spray frame, adjustable nozzles, and multi-parameter environmental sensors, this system can automatically adjust the spray mode and parameters based on operating conditions such as temperature and dust concentration within the tunnel, achieving on-demand, directional, and efficient spray control. The spray system also employs a multi-level branch network design, with each branch connecting to an independently controlled atomizing nozzle controlled by a solenoid valve. The nozzle is driven by a built-in servo motor and secured in a movable annular groove via a universal ball joint. This structure not only enables three-dimensional adjustment of the nozzle angle but also supports movement along a track on the spray support. Combined with temperature, humidity, dust concentration, and distance data collected by the intelligent sensing unit, it allows for precise control of atomization direction, position, and flow rate. Compared to existing fixed-angle spraying equipment, this invention significantly improves droplet coverage and spraying efficiency, avoiding resource waste. Simultaneously, the system features self-driving or cooperative movement capabilities, adapting to different tunnel cross-sections and work rhythms, avoiding repeated spraying and energy waste, significantly improving the utilization efficiency of the spray fluid, reducing water and energy consumption, and ensuring the safety and comfort of operators. The system's overall structure is flexible to install, suitable for various mine tunnel environments, provides ideal cooling and dust suppression effects, has a high level of intelligence, and has promising prospects for widespread application.

[0035] This invention also provides a full-section intelligent spray dust suppression and cooling method, which employs a full-section intelligent spray dust suppression and cooling system, including the following steps: Step 1: Preparation for Operation; The full-section intelligent spray dust suppression and cooling system was placed in the roadway to be operated, and its various functions were tested. During the testing of various functions, it is essential to ensure that all components are in good working order and functioning correctly. For example, ensure that the track mechanism 23 operates smoothly, that the battery pack 32 has sufficient power, that the charging interface is in normal condition, that the high-pressure pump group 8 operates smoothly, that the liquid level in the water tank 6 meets the operational requirements, that all pipe joints are in normal condition, that communication between the intelligent sensing unit 1 3, the intelligent sensing unit 2, and the intelligent control unit 5 is normal, and that the temperature sensor 34, humidity sensor 35, and dust concentration sensor 36 can collect temperature, humidity, and dust concentration signals in real time; that the top ranging sensor 42 and the side ranging sensor 43 can collect distance signal 1 and distance signal 2; that the water level sensor 41 can collect liquid level signals; that the pressure gauge 30 can collect pressure signals; and that the radar detection module can collect obstacle signals in the corresponding direction. At the same time, it is necessary to check whether the nozzle 11 can slide in the annular groove 18 to ensure that the nozzle 11 can move smoothly on the spray bracket 10. As a further optimization, during the preparation period, the full-section intelligent spray dust suppression and cooling system can be repeatedly driven through the tunnel to be operated. During the driving process, the detection data from multiple radar detection modules can be used to perform 3D modeling and path planning, thereby obtaining multiple preset driving paths in advance. In this way, during the formal operation, when an obstacle appears on a certain driving path, it can directly switch to another driving path to drive and perform spray dust suppression and cooling operations, which can more reliably achieve automatic driving, obstacle avoidance and spray dust suppression and cooling operations. Step 2: Start the spray cooling and dust suppression operation; S21: The controller obtains temperature, humidity and dust concentration data in the current working environment through temperature sensor 34, humidity sensor 35 and dust concentration sensor 36, obtains the distance data 1 between the top of the spray bracket 10 and the roof of the tunnel through top distance sensor 42, obtains the distance data 2 between the side of the spray bracket 10 and the side wall of the tunnel through side distance sensor 43, obtains the surrounding obstacle situation through multiple radar detection modules, and selects the number and number of nozzles 11 to be activated based on the temperature, humidity and dust concentration data in the current working environment, determines the spray volume and atomization direction of the selected nozzles 11 based on distance data 1 and distance data 2, and plans the travel path based on the surrounding obstacle situation; S22: The controller controls the drive motor to start working, so that the track mechanism 23 drives the support platform 1 to move along the preset path. The controller controls the main solenoid valve 31 to open, controls the motor 29 to drive the centrifugal pump 28 to start working, controls the angle of the selected nozzle 11 to rotate to the atomization direction, controls the solenoid valve 17 corresponding to the selected nozzle 11 to open, and controls the valve opening degree of the opened solenoid valve 17 to make the spray volume of the nozzle 11 reach the required spray volume, so as to carry out full-section spray dust suppression operation. Simultaneously, the real-time temperature data is compared with the preset temperature threshold. When the temperature data is higher than the preset temperature threshold, the cooling device 7 is activated to cool the water in the water tank 6 and reduce the ambient temperature using spray. When the temperature data is no higher than the preset temperature threshold, the cooling device 7 is stopped to perform comprehensive spray dust suppression and cooling operations. The number and number of nozzles 11 to be activated are adjusted according to the real-time temperature, humidity, and dust concentration data of the current working environment. The spray volume and atomization direction of the nozzles 11 to be activated are adjusted according to the real-time distance data 1 and distance data 2. As a further preferred option, when the temperature data of the current working environment is higher than the preset temperature threshold, the nozzle angle and spray frequency of the nozzles 11 performing the spray operation are first adjusted to improve the cooling response speed. After adjusting the nozzle angle and spray frequency and setting a time period, if the base temperature data is still higher than the preset temperature threshold, the cooling device 7 is activated to cool the water in the water tank 6. At the same time, the travel path is dynamically adjusted based on real-time feedback of surrounding obstacles; Simultaneously, the pressure data of the centrifugal pump 28 outlet channel is obtained from the pressure gauge 30, and the liquid level data in the water tank 6 is obtained through the water level sensor 41. The pressure data is compared with the set pressure range, and the liquid level data is compared with the set liquid level threshold. When the pressure data exceeds the predetermined pressure range or when the liquid level data is lower than the set liquid level threshold, it is determined that the current working condition is abnormal, and the alarm is controlled to perform an alarm action. At the same time, the drive motor is controlled to stop, the main solenoid valve 31 is controlled to close, the motor 29 is controlled to stop, and the solenoid valve 17 is controlled to close until the abnormal working condition disappears, and the previous working condition is restored.

[0036] To enable simultaneous spray coverage of the entire cross-section of the roadway using multiple full-section intelligent spray dust suppression and cooling systems for more efficient dust suppression and cooling operations, in step two, when multiple full-section intelligent spray dust suppression and cooling systems are deployed simultaneously in the working roadway, one full-section intelligent spray dust suppression and cooling system is designated as the master system, and the remaining multiple full-section intelligent spray dust suppression and cooling systems are designated as slave systems. The master system and the multiple slave systems are connected wirelessly. When the master system and the multiple slave systems are simultaneously performing spray dust suppression and cooling operations, the multiple slave systems report the temperature data at their respective locations. Temperature, humidity, and dust concentration data are sent to the main system. The controller in the main system sends corresponding work interval data to each slave system based on the temperature, humidity, and dust concentration data at the location of the main and slave systems. Each slave system adjusts the spacing between adjacent full-section intelligent spray dust suppression and cooling systems according to the work interval data. This allows for real-time adjustment of the spacing between multiple full-section intelligent spray dust suppression and cooling systems based on changes in temperature, humidity, and dust concentration in different areas of the tunnel, achieving coordinated and interconnected full-section spray dust suppression and cooling coverage. Through intelligent linkage control between multiple systems, the controllers built into each system can exchange information via wireless communication, automatically adjusting their spacing according to differences in the local environment, achieving adaptive layout and regional collaborative operation. This linkage mechanism can dynamically plan the spray route and coverage area based on the tunnel cross-section shape and changes in heat intensity, ensuring no blind spots in cooling and dust suppression coverage, thus meeting the actual needs of "full-section" intelligent spray operations underground.

[0037] This patent proposes a full-section intelligent spray dust suppression and cooling method, aiming to achieve full-section spray coverage in mine roadways and improve dust suppression and cooling efficiency. During operation, the cooling module and high-pressure water mist work together to achieve dual-effect dust suppression and cooling in the mine environment, significantly improving operational efficiency and greatly enhancing the dust suppression and cooling effect. This method effectively reduces blind spots in spray operations and better adapts to the heterogeneity of ventilation, heat hazards, and dust distribution in different sections, enabling "on-demand spraying." Simultaneously, the spray combined with the cooling function of the cooling module forms a "mist-cold coupling," enhancing cooling intensity and improving the thermal environment of the work area, thus improving worker comfort. During operation, the spray flow rate and angle are intelligently adjusted based on temperature, humidity, and dust concentration data, enabling variable spray arrangements within the vehicle's width and height range, providing extremely strong full-section coverage capability. Compared with existing technologies, this invention provides a full-section spray intelligent dust suppression and cooling system that can operate autonomously and adjust intelligently in complex mine environments, achieving several technological breakthroughs such as directional controllable spraying, coordinated linkage of multiple systems, and real-time environmental perception and response control.

[0038] This method is simple to implement and highly intelligent. It can achieve coordinated operation of full-section spraying and efficient cooling and dust suppression. It can also achieve on-demand, targeted, and efficient spraying dust suppression and cooling control, and can effectively solve the problems of incomplete coverage, untimely response, and cumbersome manual adjustment of existing spraying systems in high-temperature and high-dust working environments in mines.
