Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, specifically to an energy-saving heating device for agricultural planting greenhouses. Background Technology

[0002] In the Three-North Region of my country, agricultural greenhouses must be heated in winter to ensure the normal growth of crops. Existing greenhouse heating devices generally use electric heating fans to heat the inside of the greenhouse. However, since the exhaust pipes are fixed, electric heating fans are not a renewable resource. In addition, some photovoltaic panels have poor energy absorption, resulting in a certain waste of resources and poor heating effect. Therefore, it is necessary to invent an energy-saving heating device for agricultural greenhouses. Utility Model Content

[0003] The purpose of this utility model is to provide an energy-saving heating device for agricultural greenhouses to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An energy-saving heating device for an agricultural greenhouse includes a water storage tank, an inlet pipe installed at one end of the water storage tank, an outlet pipe installed at the other end of the water storage tank, an energy supply component installed at one end of the inlet pipe and the outlet pipe, an integrated water pipe installed at one end of the water storage tank, an electric auxiliary heating device installed on the surface of the integrated water pipe, and a heat sink installed at one end of the integrated water pipe.

[0006] The power supply component includes a support frame, on the surface of which an adjustment and cleaning component is mounted, and a photovoltaic panel is mounted on one end of the adjustment and cleaning component;

[0007] The adjustable cleaning component includes a locking strip, which is fixedly connected to one end of the moving block. Support plates are fixedly connected to both sides of the top of the locking strip, and a motor is fixedly connected to one side of the support plate. A rotating shaft is fixedly connected to the output end of the motor.

[0008] A further improvement of this utility model is that: a half gear is fixedly connected to the surface of the rotating shaft, a water tank is fixedly connected to the top of the half gear, and a sensor is installed on the top of the water tank to sense the temperature of the photovoltaic panel surface.

[0009] A further improvement of this utility model is that: a transmission pipe is fixedly connected to one side of the water tank, a drain pipe is installed on the other side of the water tank, and a nozzle is fixedly connected to one end of the drain pipe. The water tank transmits water to the drain pipe and sprays the water onto the photovoltaic panel through the nozzle.

[0010] A further improvement of this utility model is that: the heat sink includes a heat sink body, the heat sink body is fixedly connected to one end of the integrated water pipe, and a first heat-conducting fin, a second heat-conducting fin, and a third heat-conducting fin are sequentially fixedly connected to the surface of the heat sink body. The first heat-conducting fin, the second heat-conducting fin, and the third heat-conducting fin are arranged in a longitudinal direction to form a square array. By integrally molding and installing multiple heat-conducting fins on the heat sink body, heat is transferred to the heat-conducting fins through the heat sink body.

[0011] A further improvement of this utility model is that: the length of the second heat-conducting fin is greater than that of the first heat-conducting fin, the length of the second heat-conducting fin is greater than that of the third heat-conducting fin, and the heat-conducting fin is then transferred out. The groove between the bottom ends of multiple adjacent fins in the longitudinal direction increases the contact area between the heat dissipation fin and the air.

[0012] A further improvement of this utility model is that: grooves are provided between the first heat-conducting fin, the second heat-conducting fin, and the third heat-conducting fin, and grooves are arranged between multiple adjacent grooves in the transverse direction, which can guide the dissipated airflow to be better transferred and dissipate heat better.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] This utility model provides an energy-saving heating device for agricultural greenhouses. A sensor detects the temperature of the photovoltaic panel surface. When the temperature is too high or too low, a motor is activated. The motor drives a rotating shaft to rotate, which in turn drives a half-gear to engage with a locking strip. The rotating shaft then adjusts the angle of the photovoltaic panel. By adjusting the angle of the photovoltaic panel, it can be made to face the sun more directly, thereby increasing the amount of sunlight absorbed and helping to adapt to different seasons and geographical locations, thus providing more heating energy and achieving effective energy saving.

[0015] This utility model provides an energy-saving heating device for agricultural greenhouses. Multiple heat-conducting fins are integrally molded and installed on a heat sink body. Heat is transferred from the heat sink body to the heat-conducting fins, which then dissipate the heat. Grooves between the bottom ends of multiple adjacent fins in the longitudinal direction increase the contact area between the fins and the air, facilitating heat dissipation. Channels are arranged between multiple adjacent grooves in the transverse direction to guide the dissipated airflow for better heat dissipation. During the heat transfer process, the heat energy accumulated in the middle section is greater than that at the four sides. The second heat-conducting fin is longer than the first and third heat-conducting fins, which helps to evenly diffuse heat energy, thus improving the heating of the greenhouse. The device has a simple structure and strong practicality. Attached Figure Description

The card strip 240 is fixedly connected to one end of the moving block 23. The top two sides of the card strip 240 are fixedly connected to the support plate 241. The support plate 241 is fixedly connected to one side of the motor 242. The output end of the motor 242 is fixedly connected to the rotating shaft 243. The surface of the rotating shaft 243 is fixedly connected to the half gear 244. The top of the half gear 244 is fixedly connected to the water tank 245. The top of the water tank 245 is equipped with a sensor 246. The side of the water tank 245 is fixedly connected to the transmission pipe 247. The other side of the water tank 245 is equipped with a drain pipe 248. One end of the drain pipe 248 is fixedly connected to the nozzle 249.

[0024] Specifically, the photovoltaic panel 25 is used to absorb solar energy and transfer heat to the internal circulating water. The water outlet and water inlet of the photovoltaic panel 25 are connected to the water storage tank 1 through the water inlet pipe 3 and the water outlet pipe 4 to form a circulating water loop. The electric auxiliary heating device 6 is installed on the pipeline between the integrated water pipe 5 and the heat sink 7 to directly heat the circulating water, so as to achieve the best heating effect with the least energy consumption. To meet heating demands, an electric auxiliary heating device 6 is installed. On cloudy days or at night, it assists the solar heating unit in providing the necessary heat to meet heating needs. The integrated water pipe 5 is installed inside the water tank 245. When the photovoltaic panel 25 absorbs light energy, the sensor 246 (B3950) senses the temperature of the surface of the photovoltaic panel 25. When the temperature is too high or too low, the motor 242 (servo motor SGMAV) is started. The motor 242 drives the rotating shaft 243 to rotate. The rotating shaft 243 drives the half gear 244 to mesh and move on the clamp 240. The rotating shaft 243 drives the photovoltaic panel 25 to adjust its angle, allowing farmers to adjust the photovoltaic panel 25 according to different seasons and geographical locations, thereby improving energy output.

The water tank 245 transmits the water to the drain pipe 248 and sprays the water onto the photovoltaic panel 25 through the nozzle 249 to clean the photovoltaic panel 25.

[0025] Example 2

[0026] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heat sink 7 includes a heat sink body 70, which is fixedly connected to one end of the integrated water pipe 5. A first heat-conducting fin 72, a second heat-conducting fin 73, and a third heat-conducting fin 74 are sequentially fixedly connected to the surface of the heat sink body 70. The first heat-conducting fin 72, the second heat-conducting fin 73, and the third heat-conducting fin 74 are arranged in a square array along the longitudinal direction. The length of the second heat-conducting fin 73 is greater than that of the first heat-conducting fin 72 and the third heat-conducting fin 74. A groove 71 is formed between the first heat-conducting fin 72, the second heat-conducting fin 73, and the third heat-conducting fin 74.

[0027] Specifically, by integrally molding multiple heat-conducting fins and installing them on the heat sink body 70, heat is transferred from the heat sink body to the heat-conducting fins, and then the heat-conducting fins transfer the heat out. The grooves between the bottom ends of multiple adjacent fins in the longitudinal direction increase the contact area between the heat sink fins and the air, which is conducive to heat dissipation. The grooves 71 arranged between multiple adjacent grooves in the transverse direction can guide the dissipated airflow to better transfer and dissipate heat. In the process of heat transfer from the heat sink body 70 to the heat-conducting fins, the heat energy accumulated in the middle section is greater than the heat energy on the four sides. The length of the second heat-conducting fin 73 is greater than that of the first heat-conducting fin 72, and the length of the second heat-conducting fin 73 is greater than that of the third heat-conducting fin 74, which helps to evenly diffuse the heat energy, thereby making the heating of the greenhouse better. The structure is simple and practical.

[0028] The working principle of the energy-saving heating device in this agricultural greenhouse will be explained in detail below.

[0029] like Figure 1-4As shown, the photovoltaic panel 25 is used to absorb solar energy and transfer heat to the internal circulating water. The water outlet and water inlet of the photovoltaic panel 25 are connected to the water storage tank 1 through the water inlet pipe 3 and the water outlet pipe 4 to form a circulating water loop. The electric auxiliary heating device 6 is installed on the pipeline between the integrated water pipe 5 and the heat sink 7 to directly heat the circulating water, so as to achieve the best heating effect with the least energy consumption. To meet heating demands, an electric auxiliary heating device 6 is installed. On cloudy days or at night, it assists the solar heating unit in providing the necessary heat to meet heating needs. The integrated water pipe 5 is installed inside the water tank 245. When the photovoltaic panel 25 absorbs light energy, the sensor 246 (B3950) senses the surface temperature of the photovoltaic panel 25. When the temperature is too high or too low, the motor 242 (servo motor SGMAV) is activated. The motor 242 drives the rotating shaft 243 to rotate. The rotating shaft 243 drives the half gear 244 to mesh and move on the clamp 240. The rotating shaft 243 drives the photovoltaic panel 25 to adjust its angle, allowing farmers to adjust the photovoltaic panel 25 according to different seasons and geographical locations, thereby improving energy output. The transmission pipe 247 is used to connect to an external water source and transmit water to the water tank 245. The water tank 245 then transmits the water... Water is supplied to the drain pipe 248 and sprayed onto the photovoltaic panel 25 through the nozzle 249 to clean the photovoltaic panel 25. Multiple heat-conducting fins are integrally molded and installed on the heat sink body 70. Heat is transferred to the heat-conducting fins through the heat sink body, and then transferred out by the heat-conducting fins. Grooves between the bottom ends of multiple adjacent fins in the longitudinal direction increase the contact area between the heat sink fins and the air, which is conducive to heat dissipation. Grooves 71 are arranged between multiple adjacent grooves in the transverse direction, which can guide the dissipated airflow to better dissipate heat. In the process of heat transfer from the heat sink body 70 to the heat-conducting fins, the heat energy accumulated in the middle section is greater than that on the four sides. The length of the second heat-conducting fin 73 is greater than that of the first heat-conducting fin 72, and the length of the second heat-conducting fin 73 is greater than that of the third heat-conducting fin 74, which helps to evenly diffuse heat energy, thereby making the heating of the greenhouse better. The structure is simple and practical.
