Description

Technical Field

[0001] The utility model relates to the technical field of temperature control equipment, in particular to a temperature control device used in an agricultural greenhouse. Background Art

[0002] With the rapid development of modern agricultural technology, greenhouse cultivation has become a key means of improving crop yield and quality. Greenhouse cultivation provides a relatively stable growing environment for crops, especially during harsh climatic conditions. Greenhouses effectively control factors such as light, temperature, and humidity, ensuring normal crop growth. However, temperature management within greenhouses is a key factor influencing crop growth.

[0003] According to a search, Chinese patent document, publication number: CN215454310U, discloses a temperature control device for agricultural greenhouses. When in use, multiple devices are evenly inserted into the greenhouse. When the temperature inside the greenhouse is too high, the blower is turned on first, then the pump, and finally the atomizer. After the blower is turned on, it draws air from the vicinity of the device into the device through the air inlet hood. The outside air is then discharged through the second connecting pipe. The air discharged through the second connecting pipe first contacts the heat sink, where the temperature of the outside air drops. The pump draws water from the water tank into the atomizer, which then atomizes the water and sprays it out. The water mist sprayed from the atomizer is blown toward the upper end of the protective shell by the air discharged from the second connecting pipe. Finally, under the action of the blower, the air cooled by the heat sink and the water mist are sprayed out of the protective shell through the guide hood. The sprayed air and water mist hit the lower end of the baffle and diffuse around the device, thereby cooling the air near the device.

[0004] However, the above temperature control device still has significant defects in actual use: first, the temperature control device can only cool down but cannot heat up in winter; second, multiple devices need to be set up to control the temperature in the greenhouse, which is not conducive to reducing costs. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a temperature control device for agricultural greenhouses, which has the advantages of being able to control the temperature in various parts of the greenhouse to achieve a uniform temperature effect, and has the advantages of low cost investment, thus solving the above technical problems.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a temperature control device for an agricultural greenhouse, comprising a hot air blower, the top surface of the hot air blower is connected to two pipe brackets by screws, a nozzle is sleeved between the two pipe brackets, the outer surface of the nozzle is fixedly connected to several extension pipes, one end of the extension pipe is installed with an atomizing nozzle, one end of the nozzle is fixedly connected with a delivery pipe, one end of the delivery pipe is connected to a booster pump, the water inlet end of the booster pump is connected to a water pump, one end of the water pump is connected to a water tank, a controller is installed on the outer surface of the shell of the hot air blower, and the bottom of the shell of the hot air blower is fixedly connected to a sliding frame, the inner side of the sliding frame is rotatably connected to a moving wheel, and a driving motor is installed on one side of the sliding frame, the bottom of the sliding frame is connected to a base plate by bolts, the bottom surface of the base plate is fixedly connected to a U-shaped frame, the moving wheel rolls in contact with a guide rail, a groove is provided on the lower surface of the guide rail, a bus bar is arranged in the groove, and the bus bar slides in contact with a current collector.

[0009] Preferably, two moving wheels are rotatably connected to each side of the interior of the sliding frame, the output shaft of the drive motor is fixedly connected to one of the moving wheels, and the outer surface of the collector is connected to the hot air blower, the drive motor and the booster pump through wires.

[0010] Through the above technical solution, when the temperature in the greenhouse is too low, hot air can be transported into the greenhouse by starting the hot air blower, which can increase the temperature in the greenhouse. Since the busbar is energized in the groove, it is conductive through the contact between the collector and the busbar, and the collector is connected to the power supply line of the hot air blower, the drive motor and the booster pump through the wire, so that the hot air blower, the drive motor and the booster pump can all be connected to the power supply. When the drive motor is started, one of the moving wheels can be driven to rotate. Since the moving wheel and the guide rail are in rolling contact, the sliding frame can slide on the outer surface of the guide rail with the assistance of the other three moving wheels. By installing the guide rail inside the greenhouse, and the length of the guide rail can be made according to the length of the greenhouse, it can drive the hot air blower and other components to move in the greenhouse, and then use one hot air blower to evenly increase the temperature in the greenhouse.

[0011] Preferably, the output end of the booster pump is connected to the delivery pipe, and the bottom of the booster pump is connected to a supporting plate, and one end of the supporting plate is fixedly connected to the outer surface of the U-shaped frame.

[0012] Through the above technical solution, when the temperature in the greenhouse is too high, the water inside the water tank can be extracted by starting the booster pump in conjunction with the water pumping pipe. The water is then transported to the delivery pipe and then into the nozzle. Finally, water mist is sprayed out from several atomizing nozzles through the extension pipe, thereby cooling the inside of the greenhouse. The overall structure can heat up and cool down the greenhouse, thereby achieving the purpose of regulating temperature.

[0013] Preferably, both ends of the guide rail are fixedly connected to a crossbeam, and the bottom of the crossbeam is fixedly connected to a column.

[0016] Through the above technical solution, by setting a travel switch associated controller, when the driving motor drives the sliding frame to move to one end of the guide rail, once the sliding frame contacts the travel switch, the controller controls the driving motor to change the direction, so that the driving motor drives the moving wheel to change the rotation direction, thereby making the sliding frame reverse movement. The overall structure can make the hot air blower and other components move back and forth on the guide rail, so as to fully regulate the temperature in the greenhouse, and make the temperature in the greenhouse rise or fall evenly during the regulation process. By setting a temperature sensor, the temperature change in the greenhouse can be detected in real time. When the detected temperature value is not within the threshold range, an electrical signal is sent to the controller, and the controller is used to control the start of the hot air blower or the booster pump to achieve the purpose of automatically regulating the temperature of the greenhouse.

[0018] Through the above technical solution, a U-shaped frame is provided to support components such as the water tank and the booster pump. When the knob is loosened so that the screw drives the pressure plate to no longer contact the outer surface of the water tank, the water tank can be pulled out of the U-shaped frame to facilitate filling water into the water tank. Conversely, when the water tank is placed in the U-shaped frame, the pressure plate can be driven to stick to the outer surface of the water tank by tightening the knob, thereby achieving the purpose of fixing the water tank. The insulating pad provided can prevent the busbar from directly contacting the guide rail, thereby avoiding the problem of safety hazards caused by the guide rail being energized.

[0019] Compared with the existing technology, the present invention provides a temperature control device for agricultural greenhouses, which has the following beneficial effects:

[0020] 1. The utility model is equipped with components such as a hot air blower. When the temperature in the greenhouse is too low, the hot air blower sends hot air to increase the temperature. When the temperature is too high, the booster pump pumps water and sprays water mist through the atomizing nozzle to cool down the temperature.

In conjunction with the temperature sensor and controller, the temperature inside the greenhouse can be automatically regulated to ensure that the temperature inside the greenhouse is always suitable for the growth of crops.

[0021] 2.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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] Example 1:

[0029] See also Figure 1-Figure 3A temperature control device for an agricultural greenhouse comprises a hot air blower 1. The top surface of the hot air blower 1 is connected to two pipe brackets 2 by screws. A nozzle 3 is sleeved between the two pipe brackets 2. The outer surface of the nozzle 3 is fixedly connected to a plurality of extension pipes 4. An atomizing nozzle 5 is installed at one end of the extension pipe 4. One end of the nozzle 3 is fixedly connected to a delivery pipe 6. One end of the delivery pipe 6 is connected to a booster pump 7. The water inlet end of the booster pump 7 is connected to a water pump 8. One end of the water pump 8 is connected to a water tank 9. The outer shell of the hot air blower 1 is connected to the outer shell of the hot air blower 1. The controller 10 is mounted on the surface, and the bottom of the shell of the hot air blower 1 is fixedly connected to the sliding frame 11, the inner side of the sliding frame 11 is rotatably connected to the moving wheel 12, and a drive motor 13 is installed on one side of the sliding frame 11. The bottom of the sliding frame 11 is connected to the base plate 14 by bolts, and the bottom surface of the base plate 14 is fixedly connected to the U-shaped frame 15. The moving wheel 12 rolls in contact with the guide rail 16, and a groove 17 is provided on the lower surface of the guide rail 16. A busbar 18 is arranged in the groove 17, and the busbar 18 slides in contact with the collector 19.

[0030] Specifically, two moving wheels 12 are rotatably connected on both sides of the inner side of the sliding frame 11, the output shaft of the driving motor 13 is fixedly connected to one of the moving wheels 12, and the outer surface of the collector 19 is connected to the hot air blower 1, the driving motor 13 and the booster pump 7 through a wire. The advantage is that when the temperature in the greenhouse is too low, hot air can be transported into the greenhouse by starting the hot air blower 1, which can increase the temperature in the greenhouse. Since the busbar 18 is energized in the groove 17, it is conductive through the contact with the busbar 18 by the collector 19, and the collector 19 is connected to the power supply line of the hot air blower 1, the drive motor 13 and the booster pump 7 through the wire, so that the hot air blower 1, the drive motor 13 and the booster pump 7 can all be connected to the power supply. When the drive motor 13 is started, one of the moving wheels 12 can be driven to rotate. Since the moving wheel 12 and the guide rail 16 are in rolling contact, the sliding frame 11 can slide on the outer surface of the guide rail 16 with the assistance of the other three moving wheels 12. By installing the guide rail 16 inside the greenhouse, and the length of the guide rail 16 can be made according to the length of the greenhouse, the hot air blower 1 and other components can be driven to move in the greenhouse, and then one hot air blower 1 can be used to evenly increase the temperature in the greenhouse.

[0031] Specifically, the output end of the booster pump 7 is connected to the delivery pipe 6, and the bottom of the booster pump 7 is connected to the support plate 20, one end of which is fixedly connected to the outer surface of the U-shaped frame 15. The advantage is that when the temperature inside the greenhouse is too high, the booster pump 7 can be activated in conjunction with the water extraction pipe 8 to extract water from the water tank 9. The water is then transported to the delivery pipe 6 and then into the nozzle 3. Finally, the water mist is sprayed from the multiple atomizing nozzles 5 through the extension pipe 4, thereby cooling the interior of the greenhouse. The overall structure can achieve both heating and cooling of the greenhouse, achieving the purpose of temperature regulation.

[0032] Specifically, both ends of the guide rail 16 are fixedly connected to the crossbeam 21, and the bottom of the crossbeam 21 is fixedly connected to the column 22. The advantage is that by providing the crossbeam 21 to support the guide rail 16 and by providing the column 22 to support the crossbeam 21, the guide rail 16 is suspended in the air at a certain distance from the ground.

[0033] Example 2:

[0034] See also Figure 1 and Figure 4 , as a further improvement to the previous embodiment.

[0035] Specifically, travel switches 23 are installed at both ends of the guide rail 16, a temperature sensor 24 is installed on the top of the controller 10, an insulating pad 27 is installed inside the groove 17, and a busbar 18 is installed on the lower surface of the insulating pad 27. The advantage is that by providing the travel switch 23 in conjunction with the controller 10, when the drive motor 13 drives the slide 11 to move to one end of the guide rail 16, once the slide 11 contacts the travel switch 23, the controller 10 controls the drive motor 13 to change direction, so that the drive motor 13 drives the moving wheel 12 to change the rotation direction, thereby causing the slide 11 to reverse direction. The overall structure enables the hot air blower 1 and other components to move back and forth on the guide rail 16, so as to comprehensively control the temperature in the greenhouse. During the control process, the temperature in the greenhouse is uniformly increased or decreased. The temperature sensor 24 can detect the temperature change in the greenhouse in real time. When the detected temperature value is not within the threshold range, an electrical signal is sent to the controller 10, which controls the start of the hot air blower 1 or the booster pump 7 through the controller 10, thereby achieving the purpose of automatically controlling the greenhouse temperature.

[0036] Specifically, a knob 25 is threadedly connected to the outer surface of the U-shaped frame 15, and a pressing piece 26 is rotatably connected to the screw of the knob 25. The advantage is that by providing the U-shaped frame 15 to support components such as the water tank 9 and the booster pump 7, when the knob 25 is loosened so that the screw drives the pressing piece 26 to no longer interfere with the outer surface of the water tank 9, the water tank 9 can be pulled out of the U-shaped frame 15 to facilitate filling the water tank 9. Conversely, when the water tank 9 is placed in the U-shaped frame 15, the pressing piece 26 can be driven to cling to the outer surface of the water tank 9 by tightening the knob 25, thereby achieving the purpose of fixing the water tank 9. The insulating pad 27 can prevent the busbar 18 from directly contacting the guide rail 16, thus avoiding the problem of energizing the guide rail 16 and easily causing safety hazards.

[0037] During use, the temperature sensor 24 is used to monitor the temperature changes inside the greenhouse in real time. When it is detected that the temperature in the greenhouse is too low, the controller 10 starts the hot air blower 1 and the drive motor 13, and the hot air is transported into the greenhouse through the hot air blower 1. The drive motor 13 drives the moving wheel 12 to roll on the guide rail 16, which can drive the sliding frame 11 to move, and then drive the hot air blower 1 and other components to move. When it is detected that the temperature in the greenhouse is too high, the booster pump 7 is started and cooperated with the water pump 8 to suck the water in the water tank 9 into the delivery pipe 6, and then the water enters the nozzle 3, and then enters the extension pipe 4 and sprays water mist from the atomizing nozzle 5, thereby achieving the purpose of cooling. Since the hot air blower 1, the atomizing nozzle 5 and other components can move along the guide rail 16 driven by the sliding frame 11, this can achieve the purpose of uniform heating and cooling in the process of regulating the temperature in the greenhouse.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
