[0002] In mine construction engineering, the air supply device is the key equipment to guarantee the safety of underground operation environment and maintain production efficiency, and its core role is to transport fresh air to the mine, discharge harmful gas and dust, and assist in cooling and dehumidifying to create suitable working conditions for miners.

[0003] The existing mine construction air supply device is usually composed of a fan, a ventilation pipeline and a filter screen. The fan serves as a power source and is driven by a motor to rotate an impeller, thereby sucking air and pressurizing and conveying it to each area of the mine. The ventilation pipeline is responsible for guiding the airflow direction to ensure that the air can be accurately delivered to the working face. The filter screen is used to intercept dust and impurities in the air to ensure the cleanliness of the air supply.

[0004] Currently, the traditional air supply device has obvious deficiencies in installation and maintenance. The shell and the main frame are usually connected by bolt fastening or welding. When disassembled, tools such as wrenches are needed, which consumes a lot of time and labor, seriously affecting the efficiency of equipment maintenance, and further leading to frequent interruptions of mine construction operations. In addition, the installation method of the lighting device is fixed and difficult to quickly adjust the position according to the progress of roadway excavation or changes in the working area. When the lighting lamp or ventilation component fails, the replacement process is complex, which can easily cause insufficient lighting in the local area of the mine and increase the safety hazards of the operation. Therefore, the air supply device for mine construction is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0005] To make up for the above deficiencies, the utility model provides an air supply device for mine construction, aiming to improve the problem of time and labor consumption in the installation or maintenance of the air supply device in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An air supply device for mine construction, comprising a frame, wherein a shell one is installed on the middle part of the frame through a buckle assembly, a fixed block is fixedly connected to the top of the frame, and a lighting lamp is installed on the fixed block through a mounting and dismounting mechanism.

[0008] The buckle assembly comprises a mounting block two, which is fixedly connected to the outside of the frame. The outer side of the shell one is fixedly connected with a shell two, and the shell two is fixedly connected to the middle part of the mounting block two. A pull rod one is slidably connected to the middle part of the shell two. The outer part of the pull rod one is sleeved with a spring one. The outer part of the pull rod one is fixedly connected with a check ring. The front end of the pull rod one is fixedly connected with a pull ring.

[0009] As a further description of the above technical solution:

[0010] The buckle assembly also includes a slot, which is formed in the middle of the outer shell, and the pull rod engages with the slot.

[0011] As a further description of the above technical solution:

[0012] The loading and unloading mechanism includes a fixed component and a movable component. The fixed component includes a housing three, which is installed outside the lighting lamp. A pull rod two is slidably connected to the middle of the housing three. A spring two is sleeved on the outside of the pull rod two. A handle is fixedly connected to the front end of the pull rod two.

[0013] As a further description of the above technical solution:

[0014] The fixing component also includes a stop block, which is fixedly connected to the middle of the housing three;

[0015] As a further description of the above technical solution:

[0016] The movable component includes a mounting block one, which is installed on the outside of the fixed block. The top of the mounting block one has a latch, and the pull rod two is engaged with the latch.

[0017] As a further description of the above technical solution:

[0018] A self-cleaning dustproof net is provided in the middle of the outer casing, a fan is provided in the middle of the outer casing, and a filter is provided in the middle of the outer casing.

[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the installation and maintenance efficiency of the device is greatly improved by using the pull rod in the buckle assembly to cooperate with the slot in the middle of the outer shell. In actual mining construction operations, the traditional fixing method is time-consuming and laborious to disassemble, while the buckle assembly only requires pulling the pull ring to disengage the pull rod from the slot, which can quickly disassemble the outer shell, thereby improving the continuity and overall efficiency of mining construction operations.

[0025] 2. In this utility model, by pulling the handle in the loading and unloading assembly, the pull rod two overcomes the elastic force of the spring two and disengages from the top of the mounting block one, so that the lighting lamp can be quickly disassembled.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] ReferenceFigure 1 and Figure 4 This utility model provides an embodiment of a ventilation device for mining construction, comprising a frame 1. A housing 6 is mounted on the middle of the frame 1 via a snap-fit ​​assembly. The snap-fit ​​assembly allows for quick installation and removal of components such as a self-cleaning dustproof net 7, a fan 8, and a filter 9 for inspection and maintenance. A fixing block 17 is fixedly connected to the top of the frame 1, and a lighting lamp 18 is mounted on the fixing block 17 via a loading and unloading mechanism. The loading and unloading assembly enables flexible installation, stable fixing, and convenient removal of the lighting lamp 18, greatly improving lighting adaptability and maintenance efficiency in mining operations.

[0036] The snap-fit ​​assembly includes mounting block 2 11. When the outer shell 6 needs to be installed, it is aligned with the position. At this time, the pull rod 14 automatically snaps into the slot 24 in the middle of the outer shell 6 under the elastic force of the spring 15. The installation of the outer shell 6 can be completed quickly without the use of additional tools or complicated operations, which shortens the installation time and saves a lot of manpower and time costs compared with the traditional bolt fixing method. Mounting block 2 11 is fixedly connected to the outside of frame 1. The outer shell 6 is fixedly connected to the outside of outer shell 12. The outer shell 12 is fixedly connected to the middle of mounting block 2 11. The pull rod 14 is slidably connected to the middle of outer shell 12. The pull rod 14 is fitted with a spring 15. The spring 15 always applies an inward elastic force to the pull rod 14, so that the pull rod 14 and the slot 24 are kept in a tight snap-fit ​​state, ensuring that the outer shell 6 will not loosen or fall off due to factors such as vibration and wind pressure in the mine during the operation of the device. A retaining ring 16 is fixedly connected to the external part of the pull rod 14. The retaining ring 16 is used to limit the sliding range of the pull rod 14 and prevent the pull rod 14 from sliding excessively and detaching from the outer casing 12, further ensuring the safe operation of the air supply device. A pull ring 13 is fixedly connected to the front end of the pull rod 14. During equipment maintenance or repair, simply pull the pull ring 13 to drive the pull rod 14 to slide outward against the elastic force of the spring 15, so that the pull rod 14 disengages from the slot 24. This allows for easy disassembly of the outer casing 6, quickly exposing the self-cleaning dustproof net 7, fan 8, filter screen 9, and other components inside the device. This facilitates inspection, maintenance, and replacement operations by personnel, effectively reducing equipment downtime and improving the overall efficiency of mining operations. The buckle assembly also includes a slot 24, which is located in the middle of the outer casing 6. The pull rod 14 engages with the slot 24.

[0037] Reference Figure 5 and Figure 6The loading and unloading mechanism includes a fixed component and a movable component. The fixed component includes a housing 19, which is installed outside the lighting lamp 18. A pull rod 23 is slidably connected to the middle of the housing 19. The pull rod 23 can slide in the middle of the housing 19. When the handle 20 is pulled, the pull rod 23 overcomes the elastic force of the spring 21 and slides outward, causing the pull rod 23 to disengage from the latch 25, thus enabling the disassembly of the lighting lamp 18. The spring 21 is sleeved on the outside of the pull rod 23. The elastic force of the spring 21 ensures that the pull rod 23 always tends to engage with the latch 25 when the handle 20 is not pulled by an external force, ensuring the stability of the lighting lamp 18 after installation. The handle 20 is fixedly connected to the front end of the pull rod 23. The fixing component also includes a stop block 22, which is fixed to the middle of the outer casing 19. The stop block 22 limits the sliding stroke of the pull rod 23, preventing it from sliding excessively and detaching from the outer casing 19, thus ensuring the reliability and stability of the fixing component structure. The stop block 22 is fixedly connected to the middle of the outer casing 19. The movable component includes a mounting block 10. When the lighting lamp 18 needs to be installed, the pull rod 23 automatically engages with the latch 25 under the elastic force of the spring 21, allowing the lighting lamp 18 to be quickly and securely fixed to the top of the frame 1. The mounting block 10 is installed outside the fixing block 17, and the top of the mounting block 10 has a latch 25, which engages with the pull rod 23.

[0038] Reference Figures 1-3 The outer casing 6 has a self-cleaning dustproof net 7 in the middle. This net is primarily used to intercept larger particles of coal dust, rock dust, and other impurities in the air, preventing large dust particles from entering the fan 8, preventing impeller wear, and extending the service life of the fan 8. The fan 8 is located in the middle of the outer casing 6. It meets the fresh air requirements of mining operations, dilutes the concentration of harmful gases underground, and improves the working environment. A filter 9 is also located in the middle of the outer casing 6. The filter 9 has a nano-hydrophobic coating, possessing antistatic and hydrophobic properties. It effectively filters fine dust and prevents dust and water vapor from mixing and adhering to the filter in humid environments, further improving the cleanliness of the supplied air, protecting the respiratory health of miners, and maintaining the stable operation of the fan 8. Fixing plates 2 are fixedly connected to the outer sides of both ends of the frame 1. Screws 4 are located in the middle of the fixing plates 2, and nuts 5 are connected to the external threads of the screws 4. Two anchor bolts 3 are installed at the bottom of the fixing plates 2. Anchor 3 provides strong pull-out resistance by being driven deep into the tunnel wall, preventing the device from loosening or falling off due to the complex underground environment.

[0039] Working principle: Outside air is first filtered by the self-cleaning dustproof net 7 in the middle of the outer casing 6 to intercept large dust particles, and then purified a second time by the filter net 9 to remove fine impurities and moisture. Then it enters the fan 8. After the fan 8 is started, the purified air is pressurized and delivered to various working areas in the mine to complete the air supply process.

[0040] When it is necessary to quickly disassemble or assemble the components in the outer casing 6, pull the pull ring 13 to drive the pull rod 14 to slide outward against the elastic force of the spring 15, so that the pull rod 14 disengages from the slot 24 in the middle of the outer casing 6, and the outer casing 6 can be disassembled for easy inspection and maintenance of the internal filter and fan 8. Release the pull ring 13, the spring 15 pushes the pull rod 14 to reset, and it automatically snaps into the slot 24 to complete the installation. The operation is simple and efficient.

[0041] When the lighting lamp 18 needs to be flexibly installed and removed, or when the lighting lamp 18 is needed to illuminate the components in the housing 6, pull the handle 20 to make the pull rod 23 move upward against the elastic force of the spring 21 and disengage from the latch 25 on the top of the mounting block 10, so that the lighting lamp 18 can be removed. When operating in reverse, the pull rod 23 automatically latches into the latch 25 under the action of the spring 21, and is fixed. When it is necessary to adjust the lighting position or to inspect the lighting lamp 18, it can be quickly disassembled and moved to meet the changing needs of mining construction operation scenarios and improve the safety and efficiency of mining construction operations.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
