Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , this utility model provides a technical solution:

[0029] A heat preservation device for a vegetable growing greenhouse comprises a movable frame 1, slide rails 12 are provided on both sides of the bottom of the movable frame 1, and a moisturizing mechanism 2 is provided on the top of the movable frame 1;

[0030] The moisturizing mechanism 2 includes a water tank 201, a water flow plate 202 and several nozzles 203. The bottom of the water tank 201 is fixedly connected to the top of the mobile frame 1, the water flow plate 202 is arranged at the bottom of the mobile frame 1, and the top of the nozzle 203 is fixedly connected to the bottom of the water flow plate 202.

[0031] Specifically, such as Figure 2 As shown, the front side of the water tank 201 is fixedly connected to the pump body 7 , the front side of the pump body 7 is fixedly connected to the connecting pipe 9 , and the side of the connecting pipe 9 close to the water passing plate 202 is fixedly connected to the water passing plate 202 .

[0032] Specifically, such as Figure 2 As shown, the front side of the water tank 201 is fixedly connected to a water injection pipe 8 , the front side of the water injection pipe 8 is rotatably connected to a valve 15 , and a constant pressure hole 16 is opened on the top of the water tank 201 .

[0033] Specifically, such as Figure 1 and Figure 2 As shown, connecting columns 10 are fixedly connected to both sides of the top of the water-passing plate 202 , and the top of the connecting column 10 is fixedly connected to the bottom of the movable frame 1 .

[0034] In this embodiment: by opening the valve 15, the external water source is injected into the water tank 201 from the water injection pipe 8, and then the valve 15 is closed. When the interior of the greenhouse is dry, the pump body 7 is controlled, and the pump body 7 transports the water in the water tank 201 to the water-passing plate 202 through the connecting pipe 9. The water flows in the water-passing plate 202 and is then sprayed out from the nozzle 203 to form water mist, which is evenly sprinkled on the vegetables, increasing the air humidity and soil humidity in the greenhouse, providing a suitable growth environment for the vegetables, and avoiding the problem that the heating rod proposed in the prior art is inserted into the ground, the heating range is limited, the moisture in the soil is easily evaporated, the drying of the soil is accelerated, and it is inconvenient to replenish water in time, which easily leads to water shortage in the vegetables and affects the normal growth of vegetables.

[0035] Specifically, such as Figure 4 As shown, a heating mechanism 3 is provided on the top of the slide rail 12. The heating mechanism 3 includes a reflector 301, a lamp holder 302 and a heating lamp 303. The reflector 301 is fixedly connected to the lamp holder 302 on one side close to the lamp holder 302, and the heating lamp 303 is fixedly connected to the inside of the lamp holder 302.

[0036] Specifically, such as Figure 1 and Figure 4 As shown, a support plate 4 is fixedly connected to the bottom of the lamp holder 302 . There are three support plates 4 . The side of the support plate 4 close to the slide rail 12 is fixedly connected to the slide rail 12 . The tops of the two support plates 4 are relatively inclined.

[0037] In this embodiment: when the temperature in the greenhouse is low, turn on the heating lamp 303, the heating lamp 303 emits heat, and the heat is evenly distributed into the greenhouse through reflection and scattering by the reflector 301, thereby increasing the temperature in the greenhouse and keeping the interior of the greenhouse warm. The support plate 4 at the bottom of the lamp holder 302 is fixedly connected to the slide rail 12 to provide stable support for the lamp holder 302. The tops of the two support plates 4 are relatively inclined, so that the heat can be better radiated toward the vegetables.

[0038] Specifically, such as Figure 1 and Figure 3 As shown, fixed plates 11 are fixedly connected to both sides of the bottom of the mobile frame 1, and rollers 5 are provided on the front and rear sides of the bottom of the fixed plate 11. The bottom of the roller 5 is in movable contact with the inner wall of the slide rail 12, and mounting blocks 13 are fixedly connected to both sides of the slide rail 12. There are several mounting blocks 13 that are evenly distributed on both sides of the slide rail 12.

[0039] Specifically, such as Figure 1 and Figure 6 As shown, a pull plate 6 is fixedly connected to the rear side of the bottom of the mobile frame 1 , and handles 14 are fixedly connected to both sides of the pull plate 6 .

[0040] In this embodiment: by pulling the handle 14 on the pull plate 6 and rolling the roller 5 inside the slide rail 12, the movable rack 1, the water-passing plate 202 and the nozzle 203 can be moved on the slide rail 12, so that the position of moisturizing and heating can be adjusted conveniently to meet the needs of vegetables in different areas.

[0041] Working principle: by laying the slide rails 12 on both sides of the inside of the vegetable planting greenhouse, use external bolts to pass through the mounting block 13 to fix the slide rails 12, and then open the valve 15 to inject the external water source from the water injection pipe 8 into the water tank 201, and then close the valve 15. When the temperature in the greenhouse is low, turn on the heating lamp 303, and the heating lamp 303 emits heat. Through the reflection and scattering of the reflector 301, the heat is evenly distributed into the greenhouse, thereby increasing the temperature in the greenhouse and keeping the inside of the greenhouse warm. The support plate 4 at the bottom of the lamp frame 302 is fixedly connected to the slide rail 12 to provide stable support for the lamp frame 302. The tops of the two support plates 4 are relatively tilted, so that the heat can be better radiated toward the vegetables. When the inside of the greenhouse is dry, the pump body 7 is controlled and the pump The body 7 transports the water in the water tank 201 to the water-passing plate 202 through the connecting pipe 9. The water flows in the water-passing plate 202 and is then sprayed out from the nozzle 203 to form water mist, which is evenly sprinkled on the vegetables, increasing the air humidity and soil humidity in the greenhouse, and providing a suitable growth environment for the vegetables. By pulling the handle 14 on the pull plate 6, the movable frame 1, the water-passing plate 202 and the nozzle 203 can be moved on the slide rail 12, which is convenient for adjusting the position of moisturizing and heating to meet the needs of vegetables in different areas. This avoids the problem that after the heating rod proposed in the existing technical solution is inserted into the ground, the heating range is limited, the moisture inside the soil is easily evaporated, the drying of the soil is accelerated, and it is inconvenient to replenish water in time, which easily leads to water shortage of vegetables and affects the normal growth of vegetables.

[0042] It should be noted that the heating lamp 303 and the pump body 7 are both existing mature technologies that have been published, and are powered by an external power supply, which will not be described in detail here.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
