Detailed ways

As shown in Figures 1 to 14, the utility model includes a spray pipe 2, a pipe clamp 3, a connecting pipe 4, a water storage bucket 41 and a drainage assembly. The utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 7, the top cooling device of the greenhouse includes a spray pipe 2, a connecting pipe 4 and a water storage bucket 41, and the spray pipe 2 is arranged above the top 11 of the greenhouse main body 1 and along the main ridge 12 of the top 11 of the greenhouse. It is arranged in the length direction, and there are two slopes 13 between two adjacent positive ridges 12, and the two slopes 13 form a "V"-shaped structure. As shown in FIG. 4 , the spray pipe 2 is fixed on the main ridge 12 of the roof 11 of the greenhouse through a pipe clamp 3 . As shown in Fig. 4, Fig. 6 and Fig. 7, the pipe clamp 3 has a circular structure, and the pipe clamp 3 is set on the spray pipe 2 to fix the spray pipe 2. The bottom of the pipe clamp 3 has a column 31, and the column 31 The bottom is fixedly connected with the positive ridge 12. The effect of the pipe clamp 3 is to fix the spray pipe 2 on the main ridge 12 of the top 11 of the greenhouse.

As shown in Figure 5, the lower part of the spray pipe 2 has spray holes 21 uniformly arranged along the axial direction of the spray pipe 2. The spray holes 21 are two groups arranged on the left and right sides of the spray pipe 2. The shower holes 21 are arranged sequentially from top to bottom. The spray holes 21 are arranged up and down a plurality, so that the initial heights of the water sprayed through the spray holes 21 are different, and the landing points of the water flow on the slope 13 are also different, so as to realize the segmental cooling of the slope 13. In order to increase the area where the water sprayed from the spray hole 21 falls on the slope 13, an atomizing nozzle can also be arranged in the spray hole 21. After the water is sprayed from the atomizing nozzle, the water has a larger volume, and then the water falls on the slope. The area on 13 is larger, in order to avoid the existence of cooling dead angle.

As shown in Figures 1 and 3, one end of the connecting pipe 4 is connected to the spray pipe 2, and the other end of the connecting pipe 4 extends downwards into the water storage bucket 41 on the ground, and is connected to the water pump located in the water storage bucket 41 . The water pump in the water storage bucket 41 extracts cold water to the connecting pipe 4, and the cold water in the connecting pipe 4 flows into the spray pipe 2, and the cold water is sprayed out through the spray hole 21 under the action of water pressure to cool down the top 11 of the greenhouse.

As shown in Fig. 8, Fig. 9 and Fig. 10, after the top 11 of the greenhouse is sprayed, in order to realize the recycling and reuse of water, the utility model is also provided with a drainage assembly. The function of the drainage assembly is to classify, collect and reuse the water flowing down from the slope, that is: separately collect the water sprayed on the top 11 slope 13 of the greenhouse for irrigation; The back section water on 13 is collected separately, and after the back section water is filtered and cooled, it is used again for cooling the top of the greenhouse. During the whole process of cooling the top 11 of the greenhouse by spraying cold water, due to the presence of dust on the slope, the water sprayed on the slope 13 in the initial stage is mixed with soil impurities after flowing down from the slope, so it is recycled for use irrigation. The water sprayed on the slope 13 in the subsequent stage is relatively clean after flowing down from the slope, so it is recovered and cooled to prepare for cooling the top of the greenhouse again.

As shown in Figure 11, the drainage assembly includes a water collecting pipe 5 and a draining pipe 6. As shown in Figures 8 to 9, the water collecting pipe 5 is fixed laterally on the side wall of the greenhouse main body 1 and is coplanar with the lower intersection point of the slope 13 on the top of the greenhouse 11 , as shown in Figure 12, the side wall of the water collecting pipe 5 has a water inlet pipe 51, and the water inlet pipe 51 extends into the lower angle 14 of two adjacent slopes 13. The drainage pipe 6 is arranged vertically, and the top of the drainage pipe 6 communicates with the bottom of the water collection pipe 5 through a communication hole 53. The communication hole 53 is arranged at the bottom of the water collection pipe 5. There are two drainage assemblies, as shown in FIG. 9 , one of which is located on the right side of the greenhouse main body 1 , and the other drainage assembly is located on the left side of the greenhouse main body 1 . The lower end of the drainage pipe 6 of one of the drainage components extends into the water storage tank 7, and then the back-stage water sprayed on the top 11 of the greenhouse is recycled and reused. In order to control the flow of water between the two slopes 13 , an electric valve is provided on the water inlet pipe 51 . When the electric valve on the water inlet pipe 51 of one of the drainage assemblies is opened and the electric valve on the water inlet pipe 51 of the other drainage assembly is closed, the water between the two slopes 13 flows into the water inlet pipe 51 of one of the drainage assemblies. When closing the electric valve on the water inlet pipe 51 of one of the drainage assemblies and opening the electric valve on the water inlet pipe 51 of another drainage assembly, the water between the two slopes 13 flows into the water inlet pipe 51 of another drainage assembly. In order to realize the filtration of the water flowing into the water storage tank 7, a filter is arranged at the bottom of the drain pipe 6 of one of the drainage components to realize the filtration of impurities in the water. In order to prevent the communication hole 53 between the water collection pipe 5 and the drain pipe 6 from being blocked, the two ends of the water collection pipe 5 have air holes 52 so that the water in the water collection pipe 5 is full and overflows through the air holes 52 . The setting of air hole 52 can also maintain the pressure in the water collecting pipe 5 to ensure that the water in the angle 14 under the slope 13 can flow into the water collecting pipe 5 through the water inlet pipe 51 under the action of gravity. In order to keep the water in the water storage bucket 41, the connecting pipe 4, the spray pipe 2 and the water storage tank 7 at a constant temperature, the outside of the water storage bucket 41, the water storage tank 7, the connecting pipe 4 and the spray pipe 2 are all wrapped with thermal insulation cotton, and the water storage bucket 41 The external insulation cotton can avoid the water temperature rise caused by direct sunlight, and the external insulation cotton of the spray pipe 2 and the connecting pipe 4 can transport the cold water in the water storage bucket 41 to the slope 13, thereby ensuring the cooling effect of the cold water on the top 11 of the greenhouse .

The utility model sprays the top of the greenhouse through the setting of the spray pipe on the top wall of the greenhouse, and delivers cold water to the spray pipe to spray the top of the greenhouse, thereby cooling the top of the greenhouse. The spray pipe is placed along the main ridge of the top of the greenhouse, and the cool water sprayed from the spray pipe falls on the slope of the top of the greenhouse and flows from top to bottom along the slope, which can cool down the entire top of the greenhouse. The setting of the drainage assembly can realize the classified collection of the water after the cooling treatment, so as to facilitate different recycling and reuse.
