Description
Technical Field
[0001] This utility model belongs to the field of greenhouse technology and relates to a mobile detonation snow removal device. Background Technology
[0002] Greenhouses have advantages such as strong heat preservation and low construction cost, and have been widely used in the north. However, snow removal in greenhouses during winter has always been a problem. Currently, the commonly used snow removal methods include: (1) manual snow removal, which uses snow rakes, scrapers and other tools to push or pull the snow so that the snow slides off the greenhouse film or insulation blanket; (2) mechanical snow removal, which mainly uses snow blowers or track-type snow blowers to remove snow or vibrates the greenhouse frame through mechanical vibration to remove snow; (3) heating snow melting method; (4) chemical snow removal method. However, all four of the above snow removal methods have shortcomings. For example, manual snow removal is inefficient, takes a long time to remove large areas of snow, is labor-intensive, requires a lot of manpower, and may damage the greenhouse film due to improper operation during the removal process. Snow blowers are noisy and last for a long time, have high equipment purchase costs, and are not effective for deep snow. Track-mounted snowplows have limited snow removal range, unable to clear snow outside the tracks, and have high maintenance and upkeep costs. If the tracks malfunction or snow accumulation interferes with track operation, the snowplow will malfunction. Mechanically vibrating the greenhouse frame damages the greenhouse structure; frequent vibration shortens the greenhouse's lifespan, and snow removal efficiency is low, only achieving localized clearing. Heating-based snow melting consumes a lot of energy and has high operating costs, requiring specialized heating equipment and power supplies. Initial equipment investment is large, and repairs are complex and costly if the heating equipment malfunctions. If the snow accumulation is too large or thick, the melting speed may not keep up, and melted snow can freeze if not drained promptly. Chemical snow removal methods use chemical agents (snow-melting agents), which can pollute the soil and vegetation, and may corrode greenhouse films and metal structures. For thick snow accumulations, chemical agents alone have limited effectiveness, requiring combination with other snow removal methods. Therefore, existing snow removal methods all have drawbacks and cannot effectively solve the problem of snow accumulation on greenhouse roofs. Summary of the Invention
[0003] In view of the above-mentioned technical problems and defects, this utility model breaks with conventional snow removal methods and provides a brand-new mobile detonation snow removal device that removes snow from the roof of a greenhouse through localized detonation. The snow removal device is equipped with an angle-adjustable detonator. When it is necessary to clear snow from a localized area, the detonator is moved to the designated position, the angle of the detonator is adjusted so that it is aimed at the snow-covered area on the roof, and then the detonator is ignited. The shock wave generated by the explosive inside the detonator at the moment of combustion acts on the greenhouse film, thereby shaking off the snow on the greenhouse film and achieving the purpose of snow removal. This snow removal device has the advantages of good snow removal effect, low cost, and no impact on the service life of the greenhouse frame.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A mobile detonation snow removal device includes a slide rail installed inside a greenhouse, a mobile platform that can slide freely relative to the slide rail, two supports fixed on the mobile platform, a detonator installed between the two supports, and an angle adjustment rod for adjusting the angle of the detonator; wherein, the slide rail is arranged longitudinally along the greenhouse; the shock wave generated by the explosive in the detonator at the moment of detonation acts on the greenhouse film, and the detonator can rotate relative to the supports; the angle adjustment rod is located behind the detonator, with one end movably connected to the mobile platform and the other end movably connected to the detonator.
[0006] As a preferred embodiment of this utility model, the mobile platform is an electric mobile platform, and the inner sides of the two brackets are provided with pins. The side wall of the detonator is provided with a shaft hole at a position opposite to the pin. The pin is set in the shaft hole of the side wall of the detonator, so that the detonator can rotate relative to the bracket.
[0007] As a preferred embodiment of this invention, the detonation snow removal device further includes a controller for controlling the movement of the mobile platform.
[0008] As a preferred embodiment of this invention, the explosive material inside the detonator is a gas or a solid.
[0009] As a preferred embodiment of this invention, the detonator includes an explosion-proof body and a fuel tank; wherein, the explosion-proof body is provided with a fuel channel and an air channel, one end of the fuel channel is connected to the fuel tank and the other end is connected to the detonation chamber, and a fuel valve is provided at the end near the fuel tank; an air inlet valve is provided at the outer port of the air channel, and the other end is connected to the detonation chamber; an igniter is provided in the detonation chamber, and the end of the detonation chamber away from the fuel channel is connected to the detonation channel, and a smoke suppressor is connected to the outer port of the detonation channel; combustible gas is provided in the fuel tank, and the hot gas released by the combustible gas at the moment of combustion in the detonation chamber enters the greenhouse after passing through the detonation channel and the smoke suppressor, and the resulting shock wave acts on the greenhouse film.
[0010] As a preferred embodiment of the present invention, the combustible gas includes liquefied natural gas.
[0011] Advantages and beneficial effects of this utility model:
[0012] (1) The mobile detonation snow removal device provided by this utility model is equipped with an angle-adjustable detonator. When it is necessary to clear snow from a local area of the roof, the detonator is moved to the designated position, the angle of the detonator is adjusted so that it is aligned with the snow-covered area of the roof, and then the detonator is ignited so that the shock wave generated by the explosive in the detonator at the moment of combustion acts on the roof film, thereby shaking off the snow on the roof film and achieving the purpose of snow removal. This snow removal device can remove thick snow, has a good snow removal effect, low cost, and because it mainly acts on the roof film, it will not affect the service life of the greenhouse frame.
[0013] (2) The mobile detonation snow removal device provided by this utility model has certain advantages over existing vibration snow removal devices. First, existing vibration snow removal devices apply mechanical vibration to the greenhouse frame to dislodge snow. However, the vibration energy is easily attenuated during transmission, especially in greenhouses with large spans, where the snow removal effect is poor in areas far from the vibration source. In contrast, the shock wave propagation speed of the detonation method is fast, covering a wider area. Second, long-term vibration may cause fatigue damage to the welding points and connectors of the greenhouse frame, affecting structural stability. The short-term impact of the detonation method usually does not cause cumulative damage. In addition, vibration snow removal is more effective for loose snow, but its snow removal capacity is limited when facing compacted snow or ice crust. The detonation method can directly break up hard snow, improving adaptability. At the same time, the vibration mode needs to be precisely adjusted. Too low a frequency makes snow removal difficult, while too high a frequency may damage the greenhouse structure, making control difficult. The detonation method can achieve a more stable snow removal effect by adjusting the intensity of the shock wave. Finally, due to the limited range of vibration, it is difficult to cover a large area of snow instantly, and its efficiency is low when dealing with large-scale snowfall. In contrast, the blasting method can remove snow faster and more efficiently, reducing the risk of damage to greenhouses. Attached Figure Description
