The output shaft of the motor is connected to the baffle 5, so as to drive the baffle 5 to rotate and seal the top of the collection basin 4; an inlet 14 is provided on the baffle 5, and an installation box 6 is installed on the baffle 5. The installation box 6 is provided with two openings, one opening is connected with the inlet 14, and the other opening is used for the air to enter (a one-way valve 7 is provided on the opening to prevent the air from escaping from here), and an exhaust fan 13 is provided inside the installation box 6.

[0032] A method for improving water use efficiency of plants in arid areas, the method steps are as follows:

[0033] First, when it does not rain in the arid area, the driving member drives the baffle 5 to rotate to block the top of the collection basin 4 (to prevent the collection basin 4 from being open for a long time and reduce the probability of impurities entering the collection basin 4), and the exhaust fan 13 works to introduce outside air into the collection basin 4, so that the air flows inside the collection basin 4 and the recovery pipe 3 to dredge the collection basin 4 and the recovery pipe 3 (to prevent the rainwater collection facilities of the device from being blocked, to ensure that its rainwater collection capacity will not be weakened, and to improve the utilization rate of water in the arid area); when it rains in the arid area, the driving member drives the baffle 5 to rotate to open the top of the collection basin 4 and allow rainwater to fall into the collection basin 4;

[0034] Second, the water stored in the collection basin 4 flows into the water storage assembly 1 through the recovery pipe 3, and the drip irrigation assembly 2 uses the water in the water storage assembly 1 to drip irrigate the plants in the arid area.

[0035] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 3 A mounting groove 16 is provided on the side of the baffle 5 facing the collection basin 4, and a blocking plate 15 is slidably provided in the inner cavity of the mounting groove 16, and a reset member (spring) is provided between the blocking plate 15 and the mounting groove 16; when the baffle 5 is unfolded (the top of the collection basin 4 is open), the mounting box 6 is located at the bottom of the baffle 5; when the baffle 5 is rotated to a horizontal position and the top of the collection basin 4 is opened, the side wall of the baffle 5 will be close to the side wall of the collection basin 4, so that the blocking plate 15 is squeezed by the side wall of the collection basin 4 and moves toward the inside of the inlet 14 to block the inlet 14. In the process of collecting rainwater in the collection basin 4, rainwater or impurities will not enter the inside of the mounting box 6 through the inlet 14; when the baffle 5 is rotated to block the collection basin 4, the blocking plate 15 is squeezed and disappears, and under the action of the reset member, the blocking plate 15 moves to open the inlet 14.

[0036] In this embodiment, as a further optimized solution, please refer to Figure 6 The water storage component 1 includes a water tank 101, a filter 102 arranged in the water tank 101, a pump 103 arranged in the water tank 101, and a photovoltaic power generation component 104 arranged on the water tank 101; the filter 102 divides the water storage tank 101 into two left and right cavities, the left cavity is connected to the recovery pipe 3, the pump 103 is installed in the right cavity, and the outlet of the pump 103 is connected to the drip irrigation component 2, and the filter 102 is used to filter the water used for drip irrigation; the photovoltaic power generation component 104 uses light energy to generate electricity, and the generated electricity is used to power the electrical equipment of the device for improving the water utilization efficiency of plants in arid areas.

[0037] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 3 An adsorption layer 8 (made of sponge) is provided on one side of the baffle 5. When the baffle 5 is rotated and unfolded to open the top of the collecting basin 4, the adsorption layer 8 is located on the top of the baffle 5. When the collecting basin 4 collects rainwater, the rainwater will come into contact with the adsorption layer 8 when it falls on the baffle 5. Part of the rainwater is adsorbed by the adsorption layer 8, thereby increasing the ability to collect rainwater and reducing the probability of rainwater splashing on the baffle 5. This increases the probability of rainwater falling into the collecting basin 4, thereby increasing the rainwater collection capacity of the collecting basin 4.

[0038] Example 2

[0039] As a further optimized solution of Example 1, please refer to Figure 2 and Figure 4A plugging assembly (used to cut off the recovery pipe 3) is provided on the recovery pipe 3; wherein the plugging assembly includes a mounting cover 17, a rotating rod 18 and a partition 11, the partition 11 is arranged in the inner cavity of the recovery pipe 3, the mounting cover 17 is arranged on the outer side of the recovery pipe 3, the rotating rod 18 is rotatably arranged in the inner cavity of the mounting cover 17, and one end of the rotating rod 18 extends into the inner cavity of the recovery pipe 3 and is connected to the partition 11.

[0040] It should be noted that when there is no rainfall in the arid area, when the baffle 5 blocks the top of the collecting basin 4 and the induced draft fan 13 introduces outside air into the collecting basin 4 (the induced draft fan 13 works during the day when there is no rainfall), the rotating rod 18 is rotated to rotate the partition 11 to cut off the recovery pipe 3, so that the introduced air stays inside the collecting basin 4; after the air pressure inside the collecting basin 4 reaches a certain value, the induced draft fan 13 stops working; the moisture contained in the air inside the collecting basin 4 is liquefied into water when the temperature drops at night (due to the strong evaporation capacity in arid areas, the moisture consumption can be reduced by recovering the moisture in the air); when the liquefied water in the collecting basin 4 is recovered, the partition 11 is rotated to release the restriction on the recovery pipe 3, so that the water and air inside the collecting basin 4 are introduced into the interior of the water storage assembly 1 through the recovery pipe 3, and the air flow is used to clear the recovery pipe 3 to reduce the chance of its blockage.

[0041] It should also be noted that a controller 20 is installed on the water storage assembly 1 (the controller 20 refers to a central control device, such as a programmable logic controller, which is an existing device and is not described in detail here). The controller 20 is used to control the opening and closing of the drive member and the induced draft fan 13; when it rains, the controller 20 controls the drive member to rotate with the baffle 5 to open the top of the collection basin 4, and when it is not raining, the controller 20 controls the drive member to rotate with the baffle 5 to close the top of the collection basin 4; and the controller 20 also controls the induced draft fan 13 to start during the day when it is not raining; in order to ensure that the water in the air will liquefy, a cooling device (such as a heat exchanger) is installed on the collection basin 4.

[0042] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 4, a pull rope 12 is wound around the rotating rod 18, and a guide hole is opened on the outer wall of the collecting basin 4. The end of the pull rope 12 away from the rotating rod 18 passes through the guide hole and is connected to the baffle 5. A spring 19 is sleeved on the outer wall of the rotating rod 18, and the two ends of the spring 19 are respectively connected to the outer wall of the rotating rod 18 and the inner wall of the mounting cover 17; when the baffle 5 rotates to block the top of the collecting basin 4, the pull rope 12 will be pulled, so that the rotating rod 18 rotates with the partition 11 to cut off the recovery pipe 3, so that when the baffle 5 rotates to block the collecting basin 4, it can move synchronously with the partition 11 to block the recovery pipe 3; when the baffle 5 rotates to open the top of the collecting basin 4, the tension on the pull rope 12 disappears and relaxes, so that the tension on the rotating rod 18 disappears, and under the action of the spring 19, the rotating rod 18 rotates in the opposite direction with the partition 11 to penetrate the recovery pipe 3.

[0043] In this embodiment, as a further optimized solution, please refer to Figure 4 and Figure 5 The rotating rod 18 includes a first connecting rod 181 and a second connecting rod 182. The first connecting rod 181 is rotatably arranged in the mounting cover 17, and the second connecting rod 182 is connected to the partition 11. The first connecting rod 181 and the second connecting rod 182 are both provided with openings at one end close to each other. A screw sleeve 183 is slidably arranged in the inner cavity of one side of the opening (the opening is located on the first connecting rod 181), and a pusher 185 (electric telescopic rod) is arranged in the hole. The moving end of the pusher 185 is connected to the screw sleeve 183, and a screw 184 is fixedly arranged in the opening on the other side (the opening is located on the second connecting rod 182), one end of the screw 184 is rotated and inserted into the screw sleeve 183; when the partition 11 cuts off the recovery pipe 3, the pushing member 185 works, pushing the screw sleeve 183 to slide, so that the length of the screw 184 entering the interior of the screw sleeve 183 is increased, which is used to drive the screw 184 to rotate, so that the second connecting rod 182 rotates, so as to rotate with the partition 11, and release the restriction on the recovery pipe 3. When the baffle 5 does not rotate and unfold, the blocking effect of the blocking component can also be actively released, so that the liquefied water collected in the collection basin 4 can enter the interior of the water storage component 1 through the recovery pipe 3.

[0044] In this embodiment, as a further optimized solution, please refer to Figure 1 and Figure 2 A pressure sensor 9 is provided in the collection basin 4 (the pressure sensor 9 refers to a gas pressure sensor), and an elastic interlayer 10 (made of rubber) is installed inside the collection basin 4. The pressure sensor 9 is inside the elastic interlayer 10 to protect the pressure sensor 9; the pressure sensor 9 will continuously transmit information to the controller 20; when the induced draft fan 13 guides the outside air into the collection basin 4, the air pressure inside the collection basin 4 will gradually increase (because the sealing component cuts off the recovery pipe 3), and the controller 20 receives the pressure information continuously transmitted by the pressure sensor 9. When it is detected that the air pressure inside the collection basin 4 reaches the preset value, the controller 20 will control the induced draft fan 13 to stop working.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
