[0015] In the figure: an agricultural greenhouse 1, a plastic cover film 11, a foldable rainwater collecting gutter 2, a rainwater collecting film 22, a U-shaped bracket body 2111, a first mounting ring 2112, a support plate 212, a movable cover plate 213, a second mounting ring 2131, and a rotating shaft 214. DETAILED DESCRIPTION

[0016] The technical solution in one embodiment of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-3 :

[0018] A foldable rainwater collecting trough attached to an agricultural greenhouse, wherein the agricultural greenhouse 1 includes a frame and a plastic cover film 11 covering the frame. A foldable rainwater collecting trough 2 is attached to the lower part of the outer surface of the agricultural greenhouse 1, and the foldable rainwater collecting trough 2 includes a bracket and a rainwater collecting film 22. The bracket is arranged above the ground and has an upward opening; one side of the bracket is fixed to the frame, and both sides of the rainwater collecting film 22 are respectively connected to both sides of the bracket opening to form a rainwater collecting trough.

[0019] The foldable rainwater collecting trough 2 provided by the utility model is arranged on the lower surface of the agricultural greenhouse 1, and can introduce rainwater falling on the plastic cover film 11 above the foldable rainwater collecting trough 2 into the foldable rainwater collecting trough 2. Since the foldable rainwater collecting trough 2 is attached to the agricultural greenhouse 1, there is no need to dig a rainwater collecting trough on the ground on the side of the agricultural greenhouse 1, thereby saving manpower, material resources and financial resources without occupying additional land, and it is also a kind of protection for the soil.

[0020] To facilitate the installation and transportation of the bracket, and to ensure that the bracket is firmly connected to the agricultural greenhouse 1, the bracket includes a support plate 212 and several U-shaped bracket units, each U-shaped bracket unit includes a U-shaped bracket body 2111, the support plate 212 is fixedly connected to the frame, and the same side spacing of several U-shaped bracket units is fixed on the support plate 212.

[0021] In order to manually cover the opening of the entire foldable rainwater collecting trough 2 with the movable cover 213 when it is not raining, thereby preventing debris and dust from entering the foldable rainwater collecting trough 2, the foldable rainwater collecting trough 2 also includes a movable cover 213 and a rotating shaft 214. The two sides of the U-shaped bracket body 2111 are not of the same height, wherein the upper outer side of the high side is connected to the support plate 212, and the top of the low side is provided with a first mounting ring 2112, and the rotating shaft 214 is passed through the first mounting ring 2112. A plurality of second mounting rings 2131 are provided at the bottom of the movable cover 213, and the rotating shaft 214 is passed through the first mounting ring 2112 and the second mounting ring 2131. The movable cover 213 can be flipped through the rotating shaft 214, and the movable cover 213 can close the opening of the bracket. When the movable cover 213 closes the opening of the bracket, one side of the cover is against the high side of the U-shaped bracket body 2111.

[0022] In order to reduce the force exerted by the rain-collecting film 22 on both sides of the U-shaped bracket body 2111 , the rain-collecting film 22 is folded and arranged inside the bracket.

[0023] In order to make the rain collecting film 22 durable, the rain collecting film 22 is made of a polymer corrosion-resistant plastic film.

[0024] The working principle of this utility model is:

[0025] A water reservoir or drainage facilities connected to the water reservoir are provided below the openings on both sides of the foldable rainwater collecting trough 2. Before it rains, the movable cover 213 is flipped over. When it rains, rainwater flows into the rainwater collecting trough along the plastic cover film 11. The rainwater in the rainwater collecting trough flows into the water reservoir through the openings on both sides (or one side) or flows into the water reservoir through the drainage facilities. When it is not raining, the movable cover 213 is flipped over to seal the opening of the bracket, thereby preventing debris and dust from entering the foldable rainwater collecting trough 2.

[0026] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
