Abstract

The utility model provides a greenhouse snow removal device, which comprises a water pipe which is lead to the top end of a greenhouse, wherein the bottom end of the water pipe is communicated with water in a deep well through a water pump, and a shower nozzle is arranged on the top end of the water pipe. The greenhouse snow removal device is opened to use when the snow just falls, and uniformly sprays the water in the deep well with high relative temperature on the top portion of the greenhouse by rotating the spray nozzle, thereby enabling the snow which just falls on the top portion of the greenhouse from the sky to be impacted by the water to fall on the ground in time, achieving circulation utilization of water resource, enabling the top of the greenhouse not to have the snow, and preventing the top of the greenhouse to be damaged. The greenhouse snow removal device enables the greenhouse to fell sun exposure when the snow stops, thereby increasing requirement of crops to illumination and temperature.

Description

Snow removal device for greenhouse

technical field

The utility model relates to the technical field of agricultural planting, in particular to a device for removing falling snow on the top of a greenhouse.

Background technique

With the development of production, greenhouse production technology has been applied to many fields other than vegetable production, such as potted and cut flower cultivation, grape, strawberry, watermelon, melon, peach and citrus and other fruit trees cultivation and production, forest seedling cultivation, ornamental trees Forestry production such as the cultivation of silkworms, chickens, cattle, pigs, fish and fish fry and other aquaculture industries. The greenhouse is mainly made of bamboo and wood poles, cement poles, light steel pipes or pipes and other materials to make upright columns, tie rods, arch rods and pressure rods, and covered with plastic film to form an arched plastic greenhouse. Most of them use the windward side to build the thermal insulation wall and the leeward side to build the pillars, and lay a layer of plastic film on the pillars to prevent wind and lighting during the day, and cover the plastic film with straw curtains and other heat preservation at night.

Since the greenhouse is used in winter, and snowy weather is more common in winter, due to the limited load-bearing capacity of the frame of the greenhouse, the snow will cause the collapse of the greenhouse and cause serious economic losses; in addition, if there is snow on the roof, the The sunshine time will be reduced, and the temperature in the shed will drop, which will freeze the crops in the shed and affect the growth of the crops in the shed. Therefore, the greenhouse production technology avoids snow accumulation on the roof of the greenhouse in winter. Although many special snow removal tools are currently used to remove snow from the roof, these snow removal workers have the following defects: one is that the operation is complicated, the use cost is high, and a large amount of electric energy is needed; If it is used later, if the roof of the shed is frozen, it will affect the effect of snow removal, which is not conducive to the production of crops in the shed.

Utility model content

The utility model aims to solve the above-mentioned deficiencies, and provides a greenhouse snow removal device with simple structure, convenient operation and good snow removal effect.

In order to achieve the above effects, the utility model provides a greenhouse snow removal device, which includes a water pipe leading to the top of the greenhouse, the bottom of the water pipe communicates with the water in the deep well through a water pump, and the top of the water pipe is provided with a nozzle.

The water pipe is provided with a valve.

In order to achieve a better effect, the nozzle is a rotating nozzle.

This snow removal device is opened synchronously when it just snows to achieve better snow removal effect. Because this device uses deep well water, because the water temperature of deep well water is about 17 degrees all the year round, it is much higher than the air temperature in winter. When it snows, the air temperature is from a few degrees to about zero degrees. At this time, the water pump is turned on, and the deep well water is evenly sprayed on the top of the greenhouse through the rotating nozzle. The water flows from the roof to the ground; the other part of the snow is dissolved in time when it comes into contact with relatively high-temperature deep well water, thus accelerating the speed at which the snow is washed away or dissolved by the water, so that there will be no snow on the roof. Therefore, the damage to the roof is avoided, and the use of special snow removal tools for snow removal when the snow is accumulated on the roof is reduced. Instead, when the snow stops, the greenhouse can feel the sunlight, which improves the requirements of the crops on light and temperature.

The utility model has a simple structure, and only needs a water pipe, a water pump and a rotating nozzle to realize the purpose of snow removal in the greenhouse. The rotating nozzle makes use of the centrifugal effect of the water flow and the impetus of the reaction force to make the nozzle rotate while spraying water. Due to the large number of branch pipes of the nozzle and a certain bending direction, the sprayed water is umbrella-shaped spray, which can be sprayed in a full range. Remove the snow on the top of the greenhouse without leaving any dead ends.

The utility model utilizes deep well water to remove snow, achieves the recycling of water resources, reduces the waste of water resources, and saves water usage costs; meanwhile, because the temperature of deep well water is higher than that of tap water, the effect of snow removal is improved.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is a schematic diagram of the main view structure of the utility model;

In the figure: 1-deep well, 2-water pump, 3-greenhouse, 4-water pipe, 5-valve, 6-rotary nozzle.

Detailed ways

As shown in Figure 1, the utility model provides a greenhouse snow removal device, including a water pipe 4 leading to the top of the greenhouse 3, the bottom of the water pipe 4 communicates with the water in the deep well 1 through a water pump 2, and the top of the water pipe 4 is provided with a rotating The nozzle 6, the water pipe 4 is provided with a valve 5.

This snow removal device is opened and used synchronously when it just snows. The deep well water with relatively high temperature is used to spray it evenly on the top of the greenhouse through the rotating nozzle, so that most of the snow that has just fallen from the air to the top of the shed will be impacted by the water. The water flows from the roof to the ground; the other part of the snow is dissolved in time when it comes into contact with the relatively high temperature deep well water, thus accelerating the speed of the snow being washed away or dissolved by the water, so that there will be no snow on the roof. Therefore, damage to the shed roof is avoided. When the snow stops, the shed can feel the sunlight, which improves the requirements of the crops for light and temperature.

The above embodiments are not limited to the protection scope of the present utility model, and all modifications or variations based on the basic idea of the present utility model belong to the protection scope of the present utility model.
