The first submersible pump is fixedly connected to a water inlet pipe through a connecting pipe. The number of the water inlet pipes is two, and both of the water inlet pipes are fixedly installed at the bottom of the lower roof beam, and both of the water inlet pipes are fixedly connected to a plurality of irrigation pipes. The bottom of the irrigation pipe is fixedly connected to a fixed pipe. The utility model realizes the heating of the water source inside the water storage tank through a heat exchange pipe, can make full use of the daytime heat to play a role in warming at night, and has an irrigation function at the same time. The heat exchange pipe is arranged at the bottom of the roof beam, which can not affect the daytime lighting, and uses the heat conduction performance of the roof beam to absorb heat, which is beneficial to improving the energy-saving effect. When irrigating, the water source in the water storage tank can be used to irrigate the vegetables in the greenhouse, and at the same time, the irrigation can be ensured to be uniform, and the irrigation method can be selected according to the types of vegetables, which can avoid the waste of water resources.

[0004] Therefore, aiming at the problem that the long-term use of the above filling device will cause damage and blockage of the filling nozzle and needs to be replaced, but the existing nozzle and the whole water pipe are of an integrated structure, and the whole needs to be disassembled and replaced during disassembly, resulting in waste of cost, a structure that can replace and disassemble a single nozzle can be designed, without the need to disassemble and replace the whole, saving costs. Content of the Utility Model

[0005] In order to overcome the problem that the long-term use of the filling device will cause damage and blockage of the filling nozzle and needs to be replaced, but the existing nozzle and the whole water pipe are of an integrated structure, and the whole needs to be disassembled and replaced during disassembly, resulting in waste of cost.

Above the spray heads 12, an installation connection pipe 17 is provided. On the upper end face of the spray head 12, a sealing gasket 19 is provided. On the left and right sides inside the spray head 12, fixing grooves 24 are provided. At one end of the fixing groove 24, a slot 27 located inside the spray head 12 is opened. Inside the water pipe 11, an installation groove 16 is provided. The installation connection pipe 17 is snapped into the installation groove 16. Inside the water pipe 11, a sealing groove 18 is opened. The sealing gasket 19 is snapped into the sealing groove 18. On the left and right sides of the sealing groove 18, movable grooves 20 are opened. Inside the movable grooves 20, movable blocks 23 are provided. On one side of the movable block 23, a connection block 25 that is snapped into the fixing groove 24 is fixedly provided. At one end of the connection block 25, an insertion block 26 that is inserted into the slot 27 is fixedly provided. On the side of the movable block 23 and away from the movable block 23, a spring 21 is provided.

[0024] Please refer to Figures 1-2 , in this embodiment, the greenhouse main body 1 includes a side wall 2. On one side of the side wall 2, a fixing block 5 is provided. Inside the fixing block 5, a sliding groove is opened. On one side of the fixing block 5, a motor 4 is provided. On one side of the motor 4, a lead screw 6 located inside the sliding groove is connected. The external thread of the lead screw 6 is meshed and sleeved with a threaded block 7. On the left and right sides of the front end of the threaded block 7, arc-shaped blocks 8 are fixedly provided. A rotating shaft 9 is connected through between the two arc-shaped blocks 8. The external thread of the rotating shaft 9 is movably sleeved with an adjusting block 10. When disassembling the spray head 12, first, the movable block 23 is caused to fold to one side under the drive of the movable shaft 22. Then, when it folds, the spring 21 on the other side of the movable block 23 is compressed. When the movable block 23 folds, the connection block 25 on one side of the movable block 23 folds and displaces towards one end in the fixing groove 24. At the same time, the insertion block 26 at one end of the connection block 25 disengages from the slot 27. Finally, the spray head 12 is pulled downward to disengage the sealing gasket 19 from the sealing groove 18 to complete the disassembly.

[0025] Please refer to Figures 3-6, in this embodiment, a shed roof 3 is provided above the side wall 2. The upper end surface of the shed roof 3 is provided with a plurality of uniformly arranged reinforcing arc plates. A chute 14 is opened inside the shed roof 3. A slider 15 is slidably connected inside the chute 14. A water pipe 11 is connected between the slider 15 and the adjusting block 10. A movable shaft 22 is movably connected between the movable block 23 and the water pipe 11. An anti-slip rubber pad is provided on the surface of the movable block 23. A connecting pipe 13 is provided above the spray head 12. During installation, the installation connecting pipe 17 at one end of the spray head 12 is inserted into the installation groove 16 inside the water pipe 11. At the same time, the sealing gasket 19 on the upper end surface of the spray head 12 is snapped into the sealing groove 18 inside the water pipe 11 for sealing and fixing. Finally, the moved movable block 23 is released, so that it is ejected by the spring 21 on one side. Then the movable block 23 is ejected to one side under the drive of the movable shaft 22, so that the connecting block 25 on one side of the movable block 23 is snapped into the fixing groove 24. At the same time, the insertion block 26 at one end of the connecting block 25 is inserted into the insertion slot 27 for strengthening the fixation. This can disassemble and replace a single spray head 12, improving its use efficiency.

[0026] When working, when disassembling the spray head 12, first, the movable block 23 is flipped to one side under the drive of the movable shaft 22. When it is flipped, the spring 21 on the other side of the movable block 23 is compressed. When the movable block 23 is flipped, the connecting block 25 on one side of the movable block 23 is flipped and displaced towards one end in the fixing groove 24. At the same time, the insertion block 26 at one end of the connecting block 25 is disengaged from the insertion slot 27. Finally, the spray head 12 is pulled downwards so that the sealing gasket 19 is disengaged from the sealing groove 18 to complete the disassembly; during installation, the installation connecting pipe 17 at one end of the spray head 12 is inserted into the installation groove 16 inside the water pipe 11. At the same time, the sealing gasket 19 on the upper end surface of the spray head 12 is snapped into the sealing groove 18 inside the water pipe 11 for sealing and fixing. Finally, the moved movable block 23 is released, so that it is ejected by the spring 21 on one side. Then the movable block 23 is ejected to one side under the drive of the movable shaft 22, so that the connecting block 25 on one side of the movable block 23 is snapped into the fixing groove 24. At the same time, the insertion block 26 at one end of the connecting block 25 is inserted into the insertion slot 27 for strengthening the fixation. This can disassemble and replace a single spray head 12, improving its use efficiency.

[0027] Through the above steps, when the spray head 12 is disassembled, first, the movable block 23 is used to make it fold to one side driven by the movable shaft 22. Then, while it is folding, the spring 21 on the other side of the movable block 23 is squeezed. When the movable block 23 folds, the connecting block 25 on one side of the movable block 23 folds and displaces towards one end in the fixed slot 24. At the same time, the insertion block 26 at one end of the connecting block 25 disengages from the slot 27, which can solve the problem that the long-term use of the filling device will cause damage and blockage of the filling spray head and requires replacement. However, the existing spray head and the entire water pipe are integrated structures, and disassembly requires the disassembly and replacement of the whole, wasting costs.
