Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse rainwater collection, in particular to an automatically opening and closing rainwater collection trough attached to an agricultural greenhouse. Background Art

[0002] In some arid areas, in order to fully and timely utilize rainwater and save groundwater resources, existing agricultural greenhouses often dig a rainwater collection trough on the ground on both sides of the agricultural greenhouse, and set up a water pool for irrigation at a certain location around the agricultural greenhouse. The water pool and the rainwater collection trough are connected by a water pipe. However, digging rainwater collection troughs on the ground on both sides of the agricultural greenhouse requires occupying land. At the same time, the troughs need to be reinforced with materials such as concrete, which requires manpower, material and financial resources, and is also a kind of damage to the soil. Therefore, how to design a rainwater collection facility that does not damage land resources, and at the same time, the rainwater collection opening of the rainwater collection facility can automatically open and close to ensure the cleanliness of the rainwater collection trough is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] Preferably, the automatic opening and closing bracket mechanism includes an opening and closing bracket, a fixing plate, and a driving device. The fixing plate is provided at the lower portion of the outer surface of the agricultural greenhouse. The driving device is connected to the opening and closing bracket and drives the opening and closing of the opening and closing bracket.

[0006] Preferably, the opening and closing bracket includes two upper cross bars and a lower cross bar arranged in parallel up and down, and several connecting rods connected between the upper cross bars and the lower cross bars, and an axle seat arranged at intervals on the lower cross bar. The lower cross bar is rotatably connected to the axle seat, and a driving device is provided at one end of the cross bar.

[0007] Preferably, the connecting rod is upwardly curved.

[0008] Preferably, the driving device includes a reduction motor.

[0009] Preferably, the rain collecting film is in the shape of a bag with an opening facing upward between the opening and closing bracket and the fixing plate, forming a rain collecting bag, and a water outlet is provided on the side of the rain collecting bag.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The foldable rainwater collecting trough provided by the utility model is arranged at the lower surface of the agricultural greenhouse. Before it rains, the opening and closing bracket of the utility model automatically separates from the fixed plate under the drive of the driving device to form the rainwater collecting trough. When it rains, rainwater falling on the plastic cover film above the foldable rainwater collecting trough can be introduced into the foldable rainwater collecting trough. When it is not raining, the opening and closing bracket of the utility model automatically closes with the fixed plate under the drive of the driving device. When closed, the tops of both sides of the rainwater collecting film are connected, and the rainwater collecting film located in the automatic opening and closing bracket mechanism is in a folded shape. Debris and dust cannot enter between the rainwater collecting films on both sides, thereby ensuring the cleanliness of the rainwater collecting trough.

[0012] Since the foldable rainwater collecting gutter is attached to the agricultural greenhouse, there is no need to dig a rainwater collecting gutter on the ground on the side of the agricultural greenhouse, thereby saving manpower, material resources and financial resources and not occupying additional land. It is also a kind of protection for the soil. BRIEF DESCRIPTION OF THE DRAWINGS

In actual use, in order to facilitate the automatic opening and closing of the automatic opening and closing bracket 211 mechanism 21, the drive device can be designed as a remotely controllable drive device.

[0021] The foldable rainwater collecting trough 2 provided by the present invention is arranged at the lower surface of the agricultural greenhouse 1. Before it rains, the opening and closing bracket 211 of the present invention automatically separates from the fixed plate 212 under the drive of the driving device to form the rainwater collecting trough 2. When it rains, rainwater falling on the plastic cover film above the foldable rainwater collecting trough 2 can be introduced into the foldable rainwater collecting trough 2. When it is not raining, the opening and closing bracket 211 of the present invention automatically closes with the fixed plate 212 under the drive of the driving device. When closed, the tops of both sides of the rainwater collecting film 22 are connected, and the rainwater collecting film 22 located in the automatic opening and closing bracket 211 mechanism 21 is in a folded shape. Debris and dust cannot enter between the rainwater collecting films 22 on both sides, thereby ensuring the cleanliness of the rainwater collecting trough 2.

[0022] The automatic opening and closing bracket 211 mechanism 21 includes an opening and closing bracket 211, a fixed plate 212, and a driving device. The fixed plate 212 is provided at the lower portion of the outer surface of the agricultural greenhouse 1. The driving device is connected to the opening and closing bracket 211 and drives the opening and closing of the opening and closing bracket 211. The opening and closing bracket 211 includes two upper cross bars 2111 and lower cross bars 2112 arranged in parallel with each other, and a plurality of connecting rods 2113 connected between the upper cross bars 2111 and the lower cross bars 2112, and an axle seat 2114 spaced apart on the lower cross bar. The lower cross bar 2112 is rotatably connected to the axle seat 2114, and one end of the cross bar is provided with a driving device. This solution, which comprises the upper cross bar 2111, the lower cross bar 2112, and the plurality of connecting rods 2113 to form the opening and closing bracket 211, is not only convenient to transport and install, but also cost-effective.

[0023] The connecting rod 2113 is bent upward.

[0024] In order to make the volume of the rainwater collecting trough 2 larger when the automatic opening and closing frame is opened, the rainwater collecting trough 2 can not only collect rainwater from a part of the surface of the agricultural greenhouse 1, but also collect rainwater due to its large volume.

[0025] The driving device includes a reduction motor 213 .

[0026] In order to facilitate the discharge of rainwater in the rainwater collecting trough 2 into the water storage tank, the rainwater collecting membrane 22 is in the shape of a bag with the opening upward between the opening and closing bracket 211 and the fixing plate 212, forming a rainwater collecting bag. A water outlet 221 is provided on the side of the rainwater collecting bag, and the water outlet 221 is connected to a water outlet pipe, which is connected to the water storage tank.
