[0002] Vegetable and fruit greenhouses are a kind of frame-covered structure with excellent thermal insulation performance. They are very common in various places in my country. The rise of vegetable greenhouses has also alleviated the situation of scarce vegetables in winter, allowing people to eat vegetables and fruits grown in the summer fields in the cold winter. The rapid development of greenhouse vegetable and fruit production has not only fundamentally solved the contradiction between supply and demand of fresh vegetables in winter in northern my country, but also reduced the pressure and energy consumption caused by "transporting vegetables from the south to the north" on railway transportation; it also provides an effective way for rural industrial structure adjustment and farmers to become rich and well-off.

[0003] In the prior art, the invention with the authorization publication number CN114451194A provides a greenhouse irrigation device, including a suspension frame, a driving assembly and an irrigation mechanism. The front and rear ends of the suspension frame are provided with driving assemblies, and the driving assembly includes a swing arm, a torsion spring I, a concave friction wheel and a motor. Two swing arms are rotatably mounted on both sides of the end of the suspension frame and are arranged oppositely, and a torsion spring I is arranged between the swing arm and the suspension frame. A concave friction wheel is rotatably mounted on the swing arm, wherein the concave friction wheel is driven by a motor, and the irrigation mechanism is arranged at the bottom of the suspension frame for spraying water. The concave friction wheel can be stuck on the crossbeam of the steel structure greenhouse, thereby avoiding the need for the intervention of the guide rail for the irrigation device to move horizontally in the greenhouse, and the driving assembly is suspended on the crossbeam of the greenhouse, so it can directly detach from the crossbeam when moving to the end of the crossbeam, so the irrigation device can be transferred to different greenhouses for irrigation, which is convenient for use and operation.

[0022] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] See also Figure 1-Figure 5 The invention discloses an efficient water-saving irrigation device for a planting greenhouse, comprising a greenhouse body 1, wherein a plurality of solid blocks 2 for recovering water are placed at equal intervals at the center line of the top of the greenhouse body 1, wherein a plurality of collecting barrels 3 are installed in the greenhouse body 1 just below the solid block 2, wherein the bottom end of the collecting barrel 3 is connected to a first water pipe 5, and the other end of the first water pipe 5 is connected to a water storage tank 6 installed outside the greenhouse body 1, wherein a rainwater collecting device 7 is fixedly installed on the upper surface of the water storage tank 6, wherein a first water pump chamber 8 is installed at the center of the top surface of the water storage tank 6, wherein a first water pump 9 is fixedly installed inside the first water pump chamber 8, wherein an input end of the first water pump 9 is connected to a suction pipe 10 extending into the water storage tank 6, and an output end of the first water pump 9 is connected to a second water pipe 11 extending into the interior of the greenhouse body 1, wherein a plurality of dripping pipes 12 are installed on the second water pipe 11, wherein the lower end of the dripping pipe 12 is connected to a liquid storage pipe 13, and the bottom end of the liquid storage pipe 13 is connected to a plurality of conduits 14.

[0025] Specifically, a filter screen 15 is fixedly installed inside the water tank 6, and the bottom end of the straw 10 passes through the filter screen 15 and extends to the bottom end of the water tank 6. A water filling port 16 is also provided at the top of the water tank 6, and a screw cap is threadedly connected to the water filling pipe. When rainwater and distilled water are insufficient, the water tank 6 can be directly filled through the water filling port 16 through an external water source to meet the water needs of crops in the greenhouse.

[0026] Specifically, the rainwater collection device 7 includes a second water pump 71 and a hollow branch pipe 72 connected to the output end of the second water pump 71 and passing through the top side wall of the water storage tank 6. A third water pipe 73 is installed at the input end of the second water pump 71. The third water pipe 73 extends to the lowest point of the depression on the top surface of the greenhouse body 1, and is used to collect rainwater stored in the depression on the top surface of the greenhouse body 1 during rainy weather to avoid damage to the greenhouse body 1 under the action of gravity.

[0027] Specifically, the position on the top of the greenhouse body 1 where the solid block 2 is placed is concave downward as a whole and the lowest end of the concave is located directly above the collecting bucket 3. The corners of the solid block 2 are rounded to prevent the corners of the solid block 2 from being too sharp, which would cause the greenhouse body 1 to be damaged under the action of gravity of the solid block 2, resulting in excessive cost for replacing the greenhouse body 1.

[0028] Specifically, several brackets 4 are fixedly connected to the center of the bottom surfaces of several collecting barrels 3 by bolts, and the bottom ends of the brackets 4 are plugged into the ground. The solid blocks 2 correspond to the number of collecting barrels 3 and brackets 4 one by one. The collecting barrels 3 are supported by the brackets 4 and are close to the recessed part of the greenhouse body 1 to avoid the collection barrels 3 being too far away from the recessed part of the greenhouse body 1, causing water to fall from the outside of the collection barrels 3, thereby affecting the collection of water vapor.

[0029] Specifically, the outer wall of the filter 15 fits tightly against the inner wall of the water tank 6, and the first water pipe 5, the hollow branch pipe 72 and the water inlet 16 are all located above the filter 15, preventing external water from directly passing through the second water pipe 11. The water source is not filtered through the filter 15, causing the second water pipe 11 to be blocked, resulting in maintenance costs.

[0030] Specifically, the liquid storage tube 13 is cylindrical as a whole and is made of transparent soft plastic. It is necessary to squeeze the liquid storage tube 13 to observe whether there is water inside the liquid storage tube 13, so that water can flow out of the conduit 14. By squeezing the liquid storage tube 13, it is also possible to check whether the conduit 14 is blocked. If the conduit 14 is blocked, it is difficult to squeeze the liquid storage tube 13 into a flat shape under water pressure. If there is no blockage, it can be easily squeezed into a flat shape. At the same time, the water outflow from the end of the conduit 14 is accelerated, thereby irrigating the roots of the crops in the greenhouse.

[0031] Specifically, the end of the water outlet of the conduit 14 extends to the roots of the crops in the greenhouse body, and a plurality of small holes are provided on the side wall of the conduit 14 near the water outlet to improve the efficiency of the conduit 14 in irrigating the roots of the crops in the greenhouse.

[0032] Working principle: By installing a solid block 2 on the top of the greenhouse body 1, the greenhouse body 1 is formed into an inward concave shape, and a collection bucket 3 is placed under the concave part. Under the stimulation of high temperature outside, water vapor condenses on the inner surface of the greenhouse body 1 and drips into the collection bucket 3 through the concave part. The collected water is transported to the inside of the water storage tank 6 through the first water pipe 5. A rainwater collection device 7 is placed at the upper end of the water storage tank 6 to collect rainwater and store it in the water storage tank 6. The rainwater is then pumped into the first water pump chamber 8 through the first water pump 9. Water is sucked out from the water storage tank 6 through the suction pipe 10 and the second water pipe 11, and is transported to the inside of the liquid storage pipe 13 through the drip pipe 12 on the second water pipe 11, and is transported to the roots of crops in the greenhouse through the conduit 14. The filter net 15 arranged inside the water storage tank 6 avoids blockage of the second water pipe 11, and the water injection port 16 arranged on the water storage tank 6 is used to supply water to the crops in the greenhouse through an external water source when rainwater and distilled water are insufficient, thereby improving the efficiency of irrigation and reducing the waste of water resources.

[0033] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical solution.
