Description

Technical Field

[0001] This utility model relates to the field of metal mining technology, and in particular to a mobile microenvironment cooling vehicle for mining. Background Technology

[0002] As the mining of mineral resources such as metal ores continues to extend deeper, the problem of mine heat hazards is becoming increasingly serious, and has become one of the key factors restricting safe production and efficient mining in mines. Mine heat hazards are caused by a combination of factors, including geothermal heat, heat dissipation from mechanical and electrical equipment, and exothermic oxidation. These factors work together during the mining process, leading to a sharp rise in temperature and a significant increase in humidity in the underground working environment, thus creating an extreme high-temperature and high-humidity working environment.

[0003] Under deep mining conditions, the hazards of mine heat hazards become increasingly significant. In the high-temperature and high-humidity working environment of mines, the health of workers faces severe challenges. Research shows that high-temperature heat hazards in mines and their effective management have become recognized scientific and technological problems in the mining industry, and mine cooling technology is key to solving this problem. High-temperature and high-humidity environments not only lead to thermal imbalances in the human body, causing heat-related illnesses such as heatstroke, heat cramps, and heat exhaustion, but may also induce chronic diseases such as cardiovascular diseases, reduce the labor capacity and work efficiency of workers, and even endanger their lives. Furthermore, heat hazards also adversely affect mine production equipment, accelerating its aging process, reducing its reliability and lifespan, and increasing maintenance costs and failure rates, thus threatening the normal production order of the mine. In addition, heat hazards not only affect the mining efficiency of metal ores but also exacerbate the risk of spontaneous combustion of metal ores; in extreme cases, they may even cause major safety accidents such as fires, resulting in heavy economic losses for enterprises.

[0004] The existing heat dissipation method is a centralized ground-based cooling system, which has the following problems: underground mining operations are scattered, and there are many locations that require ventilation and cooling. The centralized cooling refrigerant transportation distance is long, the heat loss is large, and the system's operating energy consumption is high. In addition, some cooling systems have complex equipment structures, are cumbersome to install, and are difficult to maintain, so they urgently need improvement. In particular, ventilation and heat dissipation are difficult in single-ended tunnels that do not have a through-flow airflow. Underground mining operations move quickly, and traditional cooling systems have poor mobility and cannot meet the requirements of on-site use. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile microenvironment cooling vehicle for mining, which solves the problem of ventilation and heat dissipation difficulties in underground mining operations, especially in single-heading tunnels where there is no through airflow.

[0006] The technical solution of this utility model is: a mobile cooling vehicle for a mining microenvironment, comprising an articulated chassis and a cooling assembly. The cooling assembly includes a frame mounted on the articulated chassis, a refrigeration electronic control system mounted on the frame, and a cooling fan, a condenser, a compressor, an evaporator, and a blower, all located within the frame and electrically connected to the refrigeration electronic control system. A hot air outlet is provided at one end of the frame, and a cold air outlet is provided at the other end. The cooling fan is located near the hot air outlet, and the blower is located near the cold air outlet. The condenser is arranged adjacent to the cooling fan, and the evaporator is arranged adjacent to the blower. The evaporator is connected to the compressor via a first pipe, the compressor is connected to the condenser via a second pipe, and the condenser is connected to the evaporator via a third pipe.

[0007] Preferably, a filter is provided on the second pipeline.

[0008] Preferably, an expansion valve is provided on the third pipeline.

[0009] Preferably, a pressure controller is connected between the second pipeline and the first pipeline.

[0010] Preferably, a hot air exhaust duct cloth is connected to the hot air outlet, and a cold air supply duct cloth is connected to the cold air outlet.

[0011] Preferably, the cold air outlet is equipped with an air regulating valve that can adjust the opening size.

[0012] Preferably, the articulated chassis includes a frame and a chassis electronic control system, an engine assembly, a cab, a braking and steering system, and a transmission system mounted on the frame. The engine assembly is connected to the transmission system, and the chassis electronic control system is connected to the braking and steering system and the transmission system. The chassis electronic control system is located in the cab, which is located at the front end of the frame, and the cooling assembly is located at the rear end of the frame.

[0013] Preferably, the frame is also provided with a cable reel for storing and releasing cables.

[0014] Preferably, the cold air outlet is positioned facing the driver's cab.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0016] I. This utility model has significant advantages in terms of cooling efficiency: Traditional ground-based centralized cooling systems suffer a cooling efficiency loss of 20% or more after long-distance pipeline transportation. The microenvironment mobile cooling vehicle travels directly to the area requiring cooling, reducing cooling losses over long-distance pipelines;

[0017] II. Flexible Relocation: In mines with complex geological conditions and irregular tunnel layouts, traditional centralized cooling systems face significant challenges in pipeline laying, requiring numerous bends and branches, which not only increases construction costs but also manpower and time. The microenvironment mobile cooling vehicle, with its articulated chassis and self-propelled structure, can flexibly relocate to various complex tunnels.

[0018] Third, this utility model solves the problem of ventilation and heat dissipation difficulties in underground mining operations, especially in single-heading tunnels where there is no through airflow. Attached Figure Description

Detailed Implementation

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0024] like Figure 1 As shown in the figure, the mobile cooling vehicle for mining microenvironment provided in this embodiment includes a hot air exhaust duct cloth 400, a cooling assembly 200, an articulated chassis 300, and a cold air supply duct cloth 100.

[0025] like Figure 2As shown, the cooling assembly 200 includes a frame 206 mounted on a hinged chassis 300 and a refrigeration electronic control system 209 mounted on the frame 206. A hot air outlet 201 is provided at one end of the frame 206, and a cold air outlet 210 is provided at the other end. A cooling fan 202, a condenser 203, a filter 204, a compressor 205, an evaporator 207, and a blower 208 are disposed within the frame 206. The cooling fan 202, condenser 203, filter 204, compressor 205, evaporator 207, and blower 208 are electrically connected to the refrigeration electronic control system 209.

[0026] The cooling fan 202 is positioned near the hot air outlet 201, and the blower 208 is positioned near the cold air outlet 210. The condenser 203 is positioned adjacent to the cooling fan 202, and the evaporator 207 is positioned adjacent to the blower 208. Figure 3 As shown, the evaporator 207 is connected to the compressor 205 via a first pipe 213, the compressor 205 is connected to the condenser 203 via a second pipe 214, and the condenser 203 is connected to the evaporator 207 via a third pipe 215. A filter 204 is installed on the second pipe 214. An expansion valve 212 is installed on the third pipe 215. A pressure controller 211 is connected between the second pipe 214 and the first pipe 213.

[0027] The compressor 205 draws refrigerant from the low-pressure zone, compresses it, and sends it to the high-pressure zone for cooling and condensation. The refrigerant releases heat into the air through the heat sink, changing from a gaseous to a liquid state, and its pressure increases. The refrigerant then flows from the high-pressure zone to the low-pressure zone, is injected into the evaporator 207 through a capillary tube, and its pressure drops sharply, causing the liquid refrigerant to immediately turn into a gaseous state. It then absorbs a large amount of heat from the air through the heat sink.

[0028] In condenser 203, cooling fan 202 accelerates airflow, causing the high-temperature, high-pressure refrigerant gas to dissipate heat to the surrounding environment, gradually cooling and liquefying. The liquefied refrigerant then passes through filter 204 to remove any impurities it may contain.

[0029] The filtered liquid refrigerant passes through the expansion valve 212, which acts as a throttling and pressure-reducing valve, causing the liquid refrigerant pressure to decrease. When it enters the evaporator 207, it becomes a low-temperature, low-pressure gas-liquid mixture.

[0030] In evaporator 207, the low-temperature, low-pressure refrigerant absorbs heat from the surrounding air and evaporates, thus lowering the air temperature. Fan 208 delivers the cooled air from evaporator 207 through the outlet, achieving a cooling effect. Pressure controller 211 monitors the system pressure in real time to ensure stable operation within a suitable pressure range.

[0031] A hot air exhaust duct cloth 400 is connected to the hot air outlet 201, and a cold air supply duct cloth 100 is connected to the cold air outlet 210. The hot air outlet 201 and the hot air exhaust duct cloth 400 are used to exhaust the hot air generated in the cooling assembly 200, ensuring normal heat dissipation for components such as the compressor 205 and condenser 203. The hot air is exhausted to a well-ventilated location via the hot air exhaust duct cloth 400, reducing the local ambient temperature. The cold air outlet 210 is equipped with an air regulating valve, which can adjust the opening size to control the delivery range and intensity of the cold air. The cold air supply duct cloth 100 delivers the cold air generated by the cooling assembly 200 to the target area, achieving air conditioning and cooling functions.

[0032] like Figure 1 As shown, the articulated chassis 300 includes a frame 306 and a chassis electronic control system 301, an engine assembly 302, a cab 303, a braking and steering system 304, a transmission system 307, and a cable reel 305 mounted on the frame 306. The engine assembly 302 is connected to the transmission system 307, and the chassis electronic control system 301 is connected to both the braking and steering system 304 and the transmission system 307. The chassis electronic control system 301 is located within the cab 303. It centrally controls and monitors the vehicle's chassis-related electrical equipment, including the control of components such as lights and sensors, as well as the collection and transmission of vehicle operating data, providing support for the intelligent operation of the vehicle. The cab 303 is located at the front end of the frame 306 and is equipped with comfortable driving facilities and an advanced control panel. Operators can centrally control the vehicle's movement and various functional systems from within the cab 303; the instrument panel displays real-time vehicle operating parameters and system status information. The cooling assembly 200 is located at the rear end of the vehicle frame 306. The cold air supply duct cloth 100 extends out along one side of the cab 303.

[0033] The engine assembly 302 serves as the vehicle's power source, employing a high-performance engine to provide power for vehicle movement and the operation of various functional systems. The braking system 304 utilizes a wet hydraulic braking system, providing reliable braking performance and ensuring vehicle safety. The steering system within the braking and steering system 304 works in conjunction with the articulated chassis to achieve precise vehicle steering. The cable reel 305 is used to store and release cables, providing power to systems such as the cooling assembly. The transmission system 307 efficiently distributes engine power to the vehicle's drive wheels and other working components, ensuring efficient and stable power transmission.
