Description

Technical Field

[0001] This utility model relates to the field of greenhouse constant temperature and dehumidification technology, specifically a greenhouse temperature control device that is easy to adjust. Background Technology

[0002] Using air conditioning units to control temperature and humidity in greenhouses is a very common technology. However, the air outlet ducts of existing air conditioning units are generally fixed inside the greenhouse, meaning the area releasing cold / hot air remains constant. Therefore, when adjusting the crops inside the greenhouse requires changing the location of the air outlets, the only solution is to dismantle and reinstall them, which is extremely costly. Alternatively, the existing air outlet locations can be used, and crop planting methods or areas can be adjusted accordingly. This often results in the inability to adopt optimal planting density or planting area planning methods, leading to poor utilization of the greenhouse planting area and consequently reduced planting profits. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse temperature control device that is easy to adjust, comprising: a direct expansion air conditioning unit for generating hot and cold air, wherein the direct expansion air conditioning unit is fixedly installed outside the greenhouse. The output end of the direct expansion air conditioning unit is connected to the main body of the duct via an air guide pipe. Most of the pipeline of the duct main body is located inside the greenhouse, and several air outlets are opened on the duct body inside the greenhouse.

[0005] At least two sets of fixing brackets are installed along the pipeline inside the greenhouse along the main body of the air duct. Each fixing bracket set includes at least two fixing brackets located on opposite sides of the main body of the air duct. The bottoms of the fixing brackets on the same side of adjacent fixing bracket sets are connected to the same wire rope body via wire rope tensioners, forming at least two sets of wire rope groups located above opposite sides of the main body of the air duct. The main body of the air duct is hoisted onto the wire rope groups by a hoisting mechanism.

[0006] The top of the fixing frame is fixed to the greenhouse support.

The two straight sections of the U-shaped rod are provided with external threads, and two locking nuts are respectively screwed into the external threads and pressed against the outside of the U-shaped clamp.

[0012] Furthermore, the main body of the duct is a sorghum fiber fabric duct, which includes an anti-condensation textured surface layer, a polymer composite layer, and a non-combustible inner duct layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the main body of the duct of the easily adjustable greenhouse temperature control device is fixed inside the greenhouse by a hoisting method. Therefore, different fixing frames can be connected to the main body of the steel wire rope to adjust the line of the steel wire rope group as needed, thereby adaptively adjusting the arrangement of the main body of the duct suspended on the steel wire rope group.

[0016] 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. Example

[0017] An easily adjustable greenhouse temperature control device, such as Figure 1 As shown, it includes: a direct expansion air conditioning unit 1 for generating hot and cold air, which is fixedly installed outside the greenhouse. The output end of the direct expansion air conditioning unit 1 is connected to the air duct body 14 through an air guide pipe 2. Most of the pipeline of the air duct body 14 is located inside the greenhouse, and several air outlets are opened on the pipe body inside the greenhouse.

[0018] At least two sets of fixing brackets are installed along the pipeline located inside the greenhouse along the duct body 14. Each fixing bracket set includes at least two fixing brackets 3 located on opposite sides of the duct body 14. The bottoms of the fixing brackets 3 on the same side of adjacent fixing bracket sets are connected to the same wire rope body 5 via wire rope tensioners 4, forming at least two sets of wire rope groups located above opposite sides of the duct body 14. The duct body 14 is hoisted onto the wire rope groups by a hoisting mechanism. The top of the fixing brackets 3 is fixed to the greenhouse support frame.

[0019] The main body of the adjustable greenhouse temperature control device is fixed inside the greenhouse by a hoisting method. Therefore, different fixing frames can be connected to the main body of the steel wire rope to adjust the line of the steel wire rope group as needed, thereby adapting the arrangement of the main body of the air duct suspended on the steel wire rope group. In this way, the position of the air outlet of the main body of the air duct can be easily adjusted according to the needs of different crops in the greenhouse. Example

[0020] Based on the easily adjustable greenhouse temperature control device of Embodiment 1, such as Figure 4 As shown, the air duct body 14 and the air duct 2 are connected by a quick-connect mechanism; the quick-connect mechanism includes: two zipper teeth 7, one zipper tooth 8, and a zipper body 9; the two zipper teeth 7 are respectively fixedly installed on the side of the air duct 2 near the direct expansion air conditioning unit 1 and the side of the air duct body 14 near the air duct 2; the two sides of the zipper tooth 8 are respectively provided with zipper teeth corresponding to the zipper teeth 7; the zipper teeth 7 and zipper teeth 8 are matched and opened and closed by the zipper body 9.

[0021] This design allows for effective connection of the direct expansion air conditioning unit 1 and the air duct 2 at different installation positions and angles by selecting zipper teeth 28 of different lengths and shapes as needed, further increasing the installation flexibility of this utility model. Example

[0022] Based on the easily adjustable greenhouse temperature control device of Embodiment 1, such as Figure 2 As shown, the wire rope tensioner 4 includes: a connecting ring 401, on which a first stud 402 and a second stud 403 are screwed respectively. The first stud 402 has a first collar 404 at its top, and the wire rope body 5 is sleeved and fixed on the first collar 404. The second stud 403 has a first hook 405 at its top, which hooks onto the second collar 406. The second collar 406 is fixedly connected to a third stud 407, and the third stud 407 is screwed and fastened to the fixing frame 3.

[0023] At this point, by rotating the first stud 402, the first stud 402 retracts into the connecting ring 401, which tightens the wire rope body 5 fixed to the first collar 404; conversely, it loosens the wire rope body 5. By rotating the second stud 403, the connecting ring 401 moves closer to the second collar 406, which tightens the wire rope body 5 fixed to the first collar 404; conversely, it loosens the wire rope body 5. By rotating the third stud 407, the second collar 406 moves closer to the fixing frame 3, which brings the connecting ring 401 closer to the fixing frame 3, thereby tightening the wire rope body 5 fixed to the first collar 404; conversely, it loosens the wire rope body 5. Example

[0024] Based on the easily adjustable greenhouse temperature control device of Embodiment 1, such as Figure 5As shown, the hoisting mechanism includes a hoisting body 6, with a second hook 601 at the top and a fixed connection at the bottom to the duct body 14 via a fixing strap. This mechanism allows the duct body 14 to be hoisted onto the wire rope body 5. Example

[0025] Based on the easily adjustable greenhouse temperature control device of Embodiment 1, such as Figure 1 As shown, several auxiliary hoisting and fixing mechanisms are also fitted onto the main body 5 of the wire rope. Figure 3 As shown, the auxiliary hoisting and fixing mechanism includes: a suspension wire rope 10, with clamping components fixed at both ends of the suspension wire rope 10.

[0026] At this time, by clamping one end of the suspended wire rope 10 onto the support frame of the greenhouse and the other end onto the wire rope body 5, the auxiliary hoisting and fixing function of the wire rope body 5 can be achieved, so as to share the weight of the air duct body 14 borne by the wire rope body 5. Example

[0027] Based on the easily adjustable greenhouse temperature control device of Embodiment 1, such as Figure 3 As shown, the clamping assembly includes a U-shaped rod 11, a U-shaped clamp 12, and a locking nut 13. The U-shaped clamp 12 is movably sleeved on the outside of the U-shaped rod 11, forming a clamping relationship with the U-shaped rod 11 to suspend the wire rope 10. The two straight sections of the U-shaped rod 11 are provided with external threads, and the two locking nuts 13 are respectively screwed into the external threads and pressed against the outside of the U-shaped clamp 12.

[0028] At this point, one end of the suspension wire rope 10 is wrapped around the main body 5 and then looped back. A U-shaped rod 11 and a U-shaped clamp 12 are used to clamp the main body of the suspension wire rope 10 and the looped end of the rope. Two locking nuts 13 are used to lock the U-shaped clamp 12, thus securing the looped end of the rope to the main body of the suspension wire rope 10. The other end of the suspension wire rope 10 is wrapped around the support frame of the greenhouse and then looped back to lock it, thus achieving the auxiliary hoisting and fixing function of the suspension wire rope 10. This structure allows for quick locking of the main body of the suspension wire rope 10 and the looped end of the rope, facilitating user operation and allowing adjustment of the hoisting position of the suspension wire rope 10 according to the position of the duct main body 14 when necessary.

[0029] According to one embodiment of the present invention, the duct body 14 is a sorghum fiber fabric duct, and the duct body 14 includes an anti-condensation textured surface layer, a polymer composite layer, and a non-combustible inner duct layer.
