Description

Technical Field

[0001] This utility model relates to the field of agricultural facilities technology, specifically to a condensate recovery irrigation device for agricultural greenhouses. Background Technology

[0002] When both humidity and temperature difference between the inside and outside of the greenhouse are large, water droplets begin to condense on the inner surface of the greenhouse's light-transmitting covering. When the condensation accumulates to a certain level, it slides down the inner surface of the covering towards the lower end. If the condensation accumulates too quickly or fails to slide down in some places, it forms dripping. Greenhouse dripping can cause chilling injury and other induced diseases in plants, reduce greenhouse light transmittance due to condensation, and directly cause plant diseases due to high humidity.

[0003] CN216766082U discloses a greenhouse condensate collection device, comprising: a semi-U-shaped guide channel, a series hose, a tee, a support frame, a fixing plate, and an adhesive layer. The fixing plate has an adhesive layer. The semi-U-shaped guide channel is adhered to the greenhouse light-transmitting covering layer between the arched support rods at the lower end of the greenhouse via the adhesive layer, forming a U-shaped guide channel with the covering layer. Each end of the semi-U-shaped guide channel has an outlet. The series hose connects the semi-U-shaped guide channels in series, with a tee in the middle. A collection bucket is connected to the tee via the guide hose. A support frame is located on the upper inner side of the semi-U-shaped guide channel. This device can quickly and effectively collect greenhouse condensate, reducing greenhouse humidity, enhancing greenhouse light transmittance, reducing the incidence of diseases and pesticide use, and increasing crop yield. This device is low in cost, lightweight, easy to operate, and widely applicable, making it suitable for widespread adoption.

[0004] However, the technology in this patent still has some drawbacks after collecting the condensate:

[0005] Although the technology in this patent can collect condensate formed in the greenhouse, it is inconvenient to treat the collected condensate. Because there are some impurities and harmful substances in the condensate, spraying the condensate directly on the crops will have a certain impact on the growth of the crops. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Figure 1-4 As shown, this utility model provides a condensate recovery irrigation device for agricultural greenhouses. The condensate recovery irrigation device includes a semi-U-shaped guide channel 1, a manifold 2, and an irrigation unit 4. The semi-U-shaped guide channel 1 is connected to the manifold 2 through a connecting pipe 11. The semi-U-shaped guide channel 1 is fixed on the light-transmitting covering layer of the greenhouse and forms a U-shaped guide channel with the light-transmitting covering layer. After condensate forms on the light-transmitting covering layer of the greenhouse, the condensate slides down the light-transmitting covering layer into the U-shaped guide channel and flows into the manifold 2 through the connecting pipe 11. This is the prior art in the comparative case and will not be described in detail here.

[0029] The irrigation unit 4 includes an irrigation pipe 41 and an irrigation nozzle 42. The irrigation nozzle 42 is mounted on the irrigation pipe 41. By setting up the irrigation nozzle 42 and the irrigation pipe 41, when condensate enters the interior of the irrigation pipe 41, the irrigation nozzle 42 can spray the condensate onto the crops inside the greenhouse.

[0030] A filter unit 3 is installed between the manifold 2 and the irrigation unit 4. This filter unit 3 filters the collected condensate, ensuring its quality and safety and preventing damage to crops. The filter unit 3 includes a skid-mounted base 31, a sand filter 32, a sedimentation tank 33, an activated carbon filter 34, a reverse osmosis filter 35, a microfiltration filter 36, and a delivery pump 37. The sand filter 32, sedimentation tank 33, activated carbon filter 34, reverse osmosis filter 35, microfiltration filter 36, and delivery pump 37 are mounted on the skid-mounted base 31. The 36 and the transfer pump 37 are connected in sequence by a pipeline. By setting up a sand filter 32, a sedimentation tank 33, an activated carbon filter 34, a reverse osmosis filter 35, a microporous filter 36 and a transfer pump 37, the sand filter 32 can filter larger particles in the condensate and prevent impurities and silt from entering. The sedimentation tank 33 can further settle impurities and silt in the condensate. The activated carbon filter 34 can remove harmful substances such as heavy metals in the condensate. The reverse osmosis filter 35 can remove impurities such as salts and heavy metals in the condensate. The microporous filter 36 can filter smaller particles in the condensate. The transfer pump 37 can transport the filtered condensate.

[0031] A water inlet pipe 38 is installed at the inlet of the sand filter 32, and one end of the water inlet pipe 38 is installed at one end of the manifold 2. A water delivery pipe 39 is installed at the outlet of the delivery pump 37, and one end of the water delivery pipe 39 is installed at one end of the irrigation pipe 41. By setting up the water inlet pipe 38 and the water delivery pipe 39, the unfiltered condensate in the manifold 2 can enter the sand filter 32 through the water inlet pipe 38, and the delivery pump 37 can deliver the filtered condensate to the irrigation pipe 41 through the water delivery pipe 39.

[0032] The condensate recovery irrigation device also includes a support and adjustment unit 5, which includes a fixed frame 51. Several fixed frames 51 are provided, and several mounting bolts 52 are threadedly installed on one end of the fixed frame 51. By setting the mounting bolts 52, the fixed frame 51 can be easily installed on the frame at the top of the greenhouse. A mounting base 53 is provided on one side of the fixed frame 51. A through hole 54 is opened in the middle of the mounting base 53. The irrigation pipe 41 passes through the through hole 54. A rubber sleeve 55 is fixedly installed on the inner wall of the through hole 54. The inner wall of the irrigation pipe 41 and the rubber sleeve 55 are interference fit. By setting the through hole 54 and the rubber sleeve 55, after the irrigation pipe 41 passes through the through hole 54, the rubber sleeve 55 can fix the irrigation pipe 41 on the mounting base 53.

[0033] A lifting seat 56 is provided on the other side of the fixed frame 51. A guide groove 57 is provided on the fixed frame 51. A guide block 58 is slidably provided on the inner wall of the guide groove 57. One side of the guide block 58 is fixedly connected to one side of the lifting seat 56. By setting the guide groove 57 and the guide block 58, the guide block 58 can slide vertically along the inner wall of the guide groove 57, thereby enabling the lifting seat 56 to rise and fall vertically. The other side of the guide block 58 is fixedly connected to one side of the mounting base 53. By driving the lifting seat 56 to rise and fall vertically, the lifting seat 56 can cause the mounting base 53 to rise and fall vertically synchronously through the guide block 58, thereby enabling the irrigation pipe 41 and the irrigation nozzle 42 to rise and fall vertically, adjusting the height of the irrigation nozzle 42 above the ground, thereby adjusting the spraying range of the irrigation nozzle 42, reducing the number of irrigation nozzles 42 required, and thus reducing the investment cost of greenhouse irrigation.

[0034] On the other side of the fixed frame 51, there is a lead screw 59. The lead screw 59 passes through the lifting seat 56 and is threadedly connected to the lifting seat 56. On the other side of the fixed frame 51, there are two support plates 6. The lead screw 59 is rotatably connected to the two support plates 6. One end of the lead screw 59 is fixedly provided with a wheel 61. By manually rotating the wheel 61, the lead screw 59 can be rotated. The lead screw 59 can drive the lifting seat 56 to rise and fall vertically. By providing support plates 6, the support plates 6 can support the lead screw 59.

[0035] Working principle: During use, the operator manually rotates the rotating wheel 61, which causes the lead screw 59 to rotate. The lead screw 59 drives the lifting seat 56 to rise vertically. The lifting seat 56, through the guide block 58, causes the mounting seat 53 to rise vertically. The irrigation pipe 41 and irrigation nozzle 42 passing through the mounting seat 53 rise synchronously, adjusting the height of the irrigation nozzle 42 above the ground to expand the spraying range of the irrigation nozzle 42, thereby reducing the number of irrigation nozzles 42 required and thus reducing the input cost of greenhouse irrigation.

[0036] When the condensate formed by the light-transmitting covering layer of the greenhouse is collected inside the semi-U-shaped guide channel 1, the condensate flows into the manifold 2 through the connecting pipe 11, and then enters the sand filter 32 through the manifold 2 and the inlet pipe 38.

[0037] At this time, the sand filter 32 filters out larger particles in the condensate to prevent impurities and silt from entering. The sedimentation tank 33 further settles impurities and silt in the condensate. The activated carbon filter 34 removes harmful substances such as heavy metals from the condensate. The reverse osmosis filter 35 removes impurities such as salts and heavy metals from the condensate. The microporous filter 36 filters out smaller particles in the condensate. The filtered condensate is then pumped by the delivery pump 37 and enters the irrigation pipe 41 through the water delivery pipe 39. The filtered condensate is then sprayed onto the crops through the irrigation nozzle 42.

[0038] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
