Abstract
Description
Technical Field
[0001] This utility model relates to the field of greenhouse technology, specifically to a heat-insulating and heat-enhancing solar greenhouse. Background Technology
[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through and provides insulation (or heating) for cultivating plants. During seasons unsuitable for plant growth, it provides a growing period and increases yield. Greenhouses are primarily used for cultivating or raising seedlings of warm-weather plants such as vegetables, flowers, and trees during cold seasons. There are many types of greenhouses, which can be further categorized based on different roof frame materials, lighting materials, shapes, and heating conditions.
[0003] Greenhouses are usually covered with a thin film on one side to achieve heat preservation. However, because there are many gaps where the film edges contact the soil, hot air inside the greenhouse can escape, resulting in poor heat preservation. In addition, in winter, especially at night, the temperature inside the greenhouse is often low and cannot reach the normal growth temperature environment for crops. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a heat-insulating and heat-enhancing solar greenhouse, which solves the problems mentioned in the background technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulating and temperature-enhancing solar greenhouse, comprising a greenhouse body, a film, and a positioning seat. The top of the positioning seat has a groove, and a drive motor is fixedly installed on the surface of the positioning seat. A fixing chamber is fixedly installed on the inner top of the greenhouse body, and a temperature sensor is fixedly installed on the outside of the fixing chamber. A first mounting shaft and a second mounting shaft are movably installed inside the groove. A pressure roller is fixedly installed on the surface of the first mounting shaft, and a gear is fixedly installed on one side of the first mounting shaft. A pressure roller is fixedly installed on the surface of the second mounting shaft, and a gear is fixedly installed on one side of the second mounting shaft.
[0006] Preferably, a heat-insulating partition is fixedly connected to the bottom of the positioning seat, and a limit cone is movably installed on one side of the positioning seat.
[0007] Preferably, both the first pressure roller and the second pressure roller are disposed inside the groove, and both the first pressure roller and the second pressure roller are elliptical cylindrical in shape.
[0008] Preferably, the output end of the drive motor is fixedly connected to one end of the first mounting shaft, and the side of the first gear meshes with the side of the second gear.
[0009] Preferably, an electric heating wire is fixedly installed inside the fixed chamber, and the output end of the temperature sensor is electrically connected to the output end of the electric heating wire.
[0010] Preferably, a flow guide box is fixedly connected to the bottom of the fixed compartment, the top of the flow guide box is connected to the interior of the fixed compartment, both sides of the flow guide box are inclined, and both sides of the flow guide box have openings.
[0011] Preferably, a fan is fixedly installed inside the fixed chamber, and the fan is located on top of the electric heating wire.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this utility model, the bottom end of the film is set inside the groove. The drive motor can control the first mounting shaft and the second mounting shaft to rotate, thereby shortening the distance between the first and second pressure rollers. The tops of the first and second pressure rollers clamp and fix the two sides of the film respectively, thereby installing the film. The bottoms of the first and second pressure rollers are in contact with the inner wall of the groove, which can prevent gas from flowing out of the groove and prevent the film from contacting the ground, thereby improving the heat preservation performance of the greenhouse.
[0014] 2. In this utility model, the electric heating wire installed inside the fixed compartment can raise the temperature, and the fan can blow the heat out from the opening, thereby transporting it into the interior of the greenhouse, which can raise the temperature inside the greenhouse and prevent the temperature inside the greenhouse from being too low and affecting the growth of crops.

Detailed Implementation
[0021] 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.
[0022] Example 1
[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a heat-insulating and temperature-enhancing solar greenhouse, including a greenhouse body 1, a film 11, and a positioning seat 2. A groove 201 is formed on the top of the positioning seat 2. A drive motor 3 is fixedly installed on the surface of the positioning seat 2. A fixing chamber 4 is fixedly installed on the inner top of the greenhouse body 1. A temperature sensor 41 is fixedly installed on the outside of the fixing chamber 4. A first mounting shaft 5 and a second mounting shaft 6 are movably installed inside the groove 201. A pressure roller 51 is fixedly installed on the surface of the first mounting shaft 5. One side of the first mounting shaft 5 is fixed... Gear 52 is installed on the first mounting shaft 5. A pressure roller 61 is fixedly mounted on the surface of the second mounting shaft 6. Gear 62 is fixedly mounted on one side of the second mounting shaft 6. An insulation partition 21 is fixedly connected to the bottom of the positioning seat 2. A limit cone 22 is movably mounted on one side of the positioning seat 2. Both pressure rollers 51 and 61 are located inside the groove 201. Both pressure rollers 51 and 61 are elliptical cylindrical in shape. The output end of the drive motor 3 is fixedly connected to one end of the first mounting shaft 5. The side of gear 52 meshes with the side of gear 62.
[0024] In this embodiment, the bottom end of the film 11 is installed inside the positioning seat 2, which is installed on the top of the ground. At the same time, the heat insulation partition 21 is inserted into the soil to prevent heat loss from the inside of the shed 1. The limiting cone 22 is used to install and position the positioning seat 2. The drive motor 3 controls the rotation of the first mounting shaft 5. Through the meshing between the first gear 52 and the second gear 62, the second mounting shaft 6 can be driven to rotate. The first pressure roller 51 and the second pressure roller 61 rotate in opposite directions. The bottom end of the film 11 is between the first pressure roller 51 and the second pressure roller 61, so that the tops of the first pressure roller 51 and the second pressure roller 61 are close to each other to clamp and fix the film 11. The bottoms of the first pressure roller 51 and the second pressure roller 61 abut against the inner wall of the groove 201, so that the bottom of the positioning seat 2 is sealed, thereby improving the heat insulation effect inside the shed 1.
[0025] Example 2
[0026] like Figures 1-5 As shown, an electric heating wire 42 is fixedly installed inside the fixed chamber 4. The output end of the temperature sensor 41 is electrically connected to the output end of the electric heating wire 42. A flow guide box 43 is fixedly connected to the bottom of the fixed chamber 4. The top of the flow guide box 43 is connected to the inside of the fixed chamber 4. Both sides of the flow guide box 43 are inclined. An opening 431 is opened on both sides of the flow guide box 43. A fan 7 is fixedly installed inside the fixed chamber 4. The fan 7 is located on top of the electric heating wire 42.
[0027] In this embodiment, an external power supply can heat the electric heating wire 42, and starting the fan 7 can blow heat out from the opening 431, thereby flowing into the interior of the greenhouse 1 and raising its temperature. The temperature sensor 41 monitors the temperature inside the greenhouse 1 to prevent the temperature inside the greenhouse 1 from being too high and affecting the growth of crops. In addition, because the guide box 43 is tilted, the heat blown out from the opening 431 will flow along the inner wall of the greenhouse 1, preventing the high temperature from blowing directly on the crops and causing them to die.
[0028] Working principle: By installing both the greenhouse body 1 and the positioning seat 2 on the top of the ground, and inserting the insulation plate 21 at the bottom of the mounting seat 2 into the soil to reduce the gap between the positioning seat and the ground, heat loss from the inside of the greenhouse body 1 can be prevented. The limiting cone 22 is inserted into the soil to fix the positioning seat 2. The film 11 covers the top of the greenhouse body 1, and the bottom end of the film 11 is inserted into the installation groove 201. Then, the drive motor 3 is started to drive the first installation shaft 5 and the second installation shaft 6 to rotate together. The bottom end of the film 11 is between the pressure roller 51 and the pressure roller 61. At this time, the tops of the pressure roller 51 and the pressure roller 61 approach each other to clamp and fix the two sides of the film 11. At the same time, the bottoms of the pressure roller 51 and the pressure roller 61 move outward and abut against the inner wall of the groove 201, thereby improving the heat preservation effect inside the greenhouse 1. When the temperature inside the greenhouse 1 is too low, the electric heating wire 42 is heated by an external power source. At the same time, the fan 7 is started to blow heat out from the opening 431, increasing the heat transfer rate. The heat blown out from the opening 431 flows along the inner wall of the greenhouse 1 to the bottom of the greenhouse 1, causing the overall temperature inside the greenhouse 1 to rise. The temperature sensor 41 monitors the temperature. When the preset temperature inside the greenhouse 1 is too high, the temperature sensor 41 controls the electric heating wire 42 to turn off, so as to avoid the temperature inside the greenhouse 1 being too high and affecting the growth of crops.
