Description

Technical Field

[0001] This utility model belongs to the technical field of antifreeze devices, and particularly relates to the fifth-generation hot air antifreeze device. Background Technology

[0002] Plant growth requires a balanced supply of nutrients such as sunlight, water, and soil. Tea trees, in particular, have relatively high climatic requirements; when exposed to frost, many tea trees will freeze to death and are unlikely to survive. With the development of agricultural technology, specialized intelligent frost protection systems have been developed for frost protection of tea trees, orchards, and winter greenhouse vegetables. This type of equipment is described in the authorized patent CN216018687U, a bidirectional 360-degree rotating frost protection machine. This patent discloses the frost protection structure, especially the 360-degree rotation, which improves the frost protection effect and provides better frost protection.

[0003] Based on the authorized patent CN216018687U, a bidirectional 360-degree rotating anti-frost machine, gradual improvements have been made, resulting in five generations of technology: The first-generation hot air anti-frost device (application number 2025200433139) achieved dual-head bidirectional hot air delivery with 360-degree rotation, improving anti-frost efficiency compared to the original patent CN216018687U; the second-generation hot air anti-frost device (application number 2025202971244) refined the combustion device, adding a protective cover, air vents, air supply ducts, a fan, an air inlet, an air inlet hole, a wind deflector, a small air supply pipe, a windbreak grille, and air inlet components, significantly improving the hot air anti-frost device and making combustion and heat output more stable. To prevent mutual interference between the two directions of air supply to the ignition device after efficiency improvements, application number 2025200433139 was cancelled. The first-generation hot air antifreeze device, which featured a dual-head, bidirectional conveyor, was changed to a single-head device, but it can rotate 360 ​​degrees. A pushing device was also added, allowing the second-generation hot air antifreeze device to be moved to any location where needed. The third-generation hot air antifreeze device, with application number 2025203899605, achieves simultaneous long-distance frost protection for multiple plant planting areas, eliminating the need for frequent relocation of the fan unit and saving labor costs. It also eliminates the labor costs and fuel waste associated with restarting the flameout to prevent burns to workers from moving the fan unit during combustion, and avoids the risk of vegetation damage due to the fan unit's inability to provide timely heat.

[0004] The fourth-generation hot air antifreeze device with application number 2025204041786 solves the problem that when cold air arrives and the air temperature is not very low, simply driving away the cold air or slightly raising the temperature can achieve a good anti-frost and antifreeze effect, thus avoiding the waste of energy and other resources.

[0005] However, when the air temperature drops too much and becomes too low, the fourth-generation hot air antifreeze device with application number 2025204041786 can no longer expel the cold air or raise the air temperature. In this case, it is necessary to replace it with the second-generation hot air antifreeze device with application number 2025202971244, or to combine the second-generation hot air antifreeze device with the third-generation hot air antifreeze device with application number 2025203899605 to achieve frost and freeze prevention. Replacement is quite troublesome, and manufacturing the second-generation hot air antifreeze device (application number: 2025202971244), the third-generation hot air antifreeze device (application number: 2025203899605), and the fourth-generation hot air antifreeze device (application number: 2025204041786) separately all require considerable expense. The cost of using these devices is not low for enterprises, putting pressure on them. Therefore, it is necessary to design a fifth-generation hot air antifreeze device that can solve the above problems, namely, a device that is suitable for both when cold air has just arrived and when the air temperature is not very low, and also for when the air temperature is very low. Utility Model Content

This replacement is cumbersome, and manufacturing the second-generation hot air antifreeze device (application number 2025202971244), the third-generation hot air antifreeze device (application number 2025203899605), and the fourth-generation hot air antifreeze device (application number 2025204041786) individually requires significant investment, placing a burden on businesses due to the high cost of using these devices.

[0047] Reference Figure 1-5 The fifth-generation hot air antifreeze device includes a fan unit;

[0048] The top of the fan unit is equipped with a solar power supply device 1 and a bird deterrent device 2. The fan unit includes a combustion chamber 3, with a blower fan 4 installed at one end of the combustion chamber 3 and an annular spray device 5 installed at the other end.

[0049] The spraying device includes a spray chamber 51 connected to the combustion chamber 3, and a plurality of spray heads 52 are installed at the end of the spray chamber 51 away from the combustion chamber 3;

[0050] A water supply pipe 6 extends into the spray chamber 51. One end of the water supply pipe 6 that extends into the spray chamber 51 is connected to an atomizing nozzle 7, and the other end that is away from the spray chamber 51 is connected to a water tank 8.

[0051] The combustion chamber 3 is equipped with an ignition element 9 and an oil supply element 10 for supplying oil during ignition. The oil supply element 10 is connected to an oil supply pipe 11, and the oil supply pipe 11 is connected to an oil supply tank 12.

[0052] The fan unit is rotatably connected to a three-dimensional support 13, and a maintenance platform 14 is installed on the support 13. A support frame 15 is rotatably connected to the outer wall of the fan unit. The support frame 15 is connected to the support 13, and a gap is formed between the fan unit and the support 13, which allows the fan unit to pass through.

[0053] Further preferred: the solar power supply device 1 and the bird deterrent device 2 are detachably connected to the fan device.

[0054] A further preferred embodiment: the support 13 is hollow, and the water pipe 6 passes through the inside of the support 13 and enters the spray chamber 51.

[0055] A further preferred embodiment is that the spray chamber 51 is not connected to the combustion chamber 3.

[0056] A further preferred embodiment: the spray heads 52 are evenly installed on the outer edge of the spray chamber 51, with the nozzles of the spray heads 52 located on the lower edge of the spray chamber 51 facing downwards.

[0057] A further preferred embodiment: the oil supply tank 12 is installed on top of the blower unit.

[0058] A further preferred embodiment: the support 13 is equipped with foot pedals 18 for climbing.

[0059] A further preferred embodiment: the maintenance table 14 is detachably connected to the bracket 13 via clamp 17.

[0060] A further preferred embodiment: a moving device 16 with braking function is installed at the bottom of the bracket 13, and the water tank 8 is installed on the moving device 16.

[0061] A further preferred embodiment is that the support 13 is made of a telescopic rod with telescopic function, and the height of the support 13 is 1 meter to 10 meters.

[0062] Basic working principle of this utility model:

[0063] When the cold air arrives and the air temperature is not yet very low, the high-pressure water pump is turned on, so that the water in the water tank 8 is pumped through the water inlet pipe 6 to the atomizing nozzle 7 under the action of the high-pressure water pump. After being atomized by the atomizing nozzle 7, the water is sprayed out from the spray head 52 through the spray chamber 51.

[0064] When the air temperature is too low, the oil pump is turned on. Under the action of the oil pump, the water in the oil supply tank 12 is sent to the oil supply component 10 through the oil supply pipe 11 and ignited by the ignition component 9. The heat generated by the combustion is sent out to the vegetation that needs to be protected from frost and freezing by the blower fan 4.

[0065] The solar power unit 1 provides electricity to the fan unit and the ring-shaped spray device 5, enabling the entire device to operate. The bird repeller 2 can be used to repel birds from vegetation, especially fruits and vegetables, preventing them from being pecked and damaged by birds, thus avoiding economic losses.

[0066] The solar power supply device 1 and the bird repeller 2 are detachably connected to the fan unit. They can be removed for cleaning to prevent dust or impurities from entering and causing the solar power supply device 1 to stop supplying power or the bird repeller 2 to stop emitting sound and thus fail to repel birds. Their locations can also be interchanged, allowing the solar power supply device 1 or the bird repeller 2 to be installed in different locations.

[0067] The maintenance platform 14 allows workers to step onto it via foot pedal 18 for extended maintenance. The large area of ​​the maintenance platform 14 provides workers with sufficient space to move around and enables maintenance from multiple angles. It is securely and stably fixed by clamps 17, preventing workers from falling over due to fatigue from prolonged maintenance or from forgetting their surroundings.

[0068] When the cold air arrives and the air temperature is not yet very low, the high-pressure water pump is turned on, so that the water in the water tank 8 enters the water inlet pipe 6 under the action of the high-pressure water pump. After passing through the water inlet pipe 6, it goes to the atomizing nozzle 7 for atomization. The atomized water is sprayed out from the spray head 52 installed on the outer edge of the spray chamber 51 through the spray chamber 51 and sprayed towards the vegetation that needs to be protected against frost and freezing.

[0069] The atomized water mist, under pressure, is sprayed upwards towards the vegetation, pushing the air above it downwards. The frost-prevention machine primarily utilizes temperature inversion to raise the ground temperature. When frost occurs, as heat dissipates from the ground, an inversion layer forms 6 to 10 meters above the ground. The temperature difference between this layer and the ground temperature can be as high as 4-6 degrees Celsius. The equipment uses a fan to turbulent the airflow, neutralizing the ground temperature to achieve the frost-prevention effect. This device is typically installed at a height of 6 to 8 meters, where the temperature is highest. The gravity and pressure of the mist rapidly blow the relatively warm air from the upper atmosphere towards the fruit trees. This relatively warm air creates convection with the cold air at lower altitudes, raising the temperature of the lower atmosphere and increasing the overall vegetation temperature by 2 to 3 degrees Celsius. Compared to traditional methods that rely solely on blowing air without the pressure and gravity of the mist, this method quickly replaces cold air with relatively warm air, increasing efficiency by 2 to 3 times.

[0070] Antifreeze can also be added to the water tank 8. The atomizing nozzle 7 atomizes the water containing antifreeze. After atomization, the water is sprayed out from the spray head 52 installed on the outer edge of the spray chamber 51 through the spray chamber 51. The antifreeze is sprayed onto the vegetation that needs frost protection, especially fruits and vegetables, to prevent them from freezing and causing heavy losses. This can achieve a better frost protection effect.

[0071] Add insecticide to the water in tank 8 and spray it onto the vegetation, especially fruits and vegetables, through this device to achieve better pest control.

[0072] The spray can also combat drought, etc. By using the fourth-generation hot air antifreeze device to spray the vegetation, especially fruit plants, it can prevent sunburn on the fruit surface after the fruit is removed from the bag, increase the fruit harvest rate, make the fruit color faster, and increase the probability of high quality.

[0073] During the high temperatures of spring, activating the fourth-generation hot air antifreeze device can effectively lower the temperature, thus ensuring the fruit set rate in the orchard. During the high temperatures of summer, activating the ring-shaped spray device 5 can effectively improve the quality of the orchard's fruit.

[0074] The fan unit is rotatably connected to the bracket 13 and the support frame 15, and the gap between the fan unit and the bracket 13 allows the fan unit to pass through, thus enabling fully automatic 360-degree unlimited rotation of the fan unit. The rotation angle can also be set to any angle from 0 to 360 degrees according to the actual terrain. It automatically swings up and down, for example, from 10 to 30 degrees, to achieve a wave-like airflow for optimal anti-frost effect. Automatic start and stop can also be set by temperature.

[0075] When the air temperature is too low, the oil pump is turned on. Under the action of the oil pump, combustion occurs in the combustion chamber 3 of the blower unit, generating heat with a temperature ranging from 0 to 2000 degrees Celsius, typically between 1000 and 1500 degrees Celsius, and usually maintained at 1100 to 1200 degrees Celsius. The blower fan 4 installed at one end of the combustion chamber 3 can simultaneously provide airflow to aid combustion during ignition in the combustion chamber 31, and also cool the heat generated by combustion in the combustion chamber 3, reducing the temperature from the usually maintained 1100 to 1200 degrees Celsius to 30 to 40 degrees Celsius.

[0076] Hot air is blown from combustion chamber 3 towards the vegetation above, and under the action of air pressure, it spreads to the surrounding areas, thus protecting the surrounding vegetation or replenishing it with heat.

[0077] Water tank 8 is installed at the bottom of bracket 13 for easy water addition.

[0078] The support 13 is hollow, and the water supply pipe 6 passes through the inside of the support 13 and enters the spray chamber 51, which avoids the water supply pipe 6 being directly exposed to the air and aging quickly.

[0079] The spray chamber 51 and the combustion chamber 3 are not connected, thus avoiding direct mutual influence between the two.

[0080] The oil supply tank 12 is installed on the top of the fan unit. A small amount of oil combustion will generate a large amount of heat. Once the oil supply tank 12 is full of oil, it can be used for a period of time without the need to frequently add oil to the oil supply tank 12. On the contrary, the speed at which oil is supplied to the oil supply component 10 is very important, so that the entire device can burn quickly when ignited. Therefore, the oil supply tank 12 is installed on the top of the fan unit to facilitate rapid oil supply.

[0081] The spray chamber 51 is annular and hollow. The spray heads 52 are evenly installed on the outer edge of the spray chamber 51. The nozzles of the spray heads 52 located on the lower edge of the spray chamber 51 face downwards. The downward-facing nozzles reduce the effect of the high-pressure water pump pressure under the action of gravity, and directly spray the vegetation directly below it, avoiding missing the vegetation directly below the fan device.

[0082] The support frame 13 is equipped with footboards 18 for climbing, which allows workers to climb onto the fan unit for maintenance, improving work efficiency and avoiding delays in use due to maintenance.

[0083] The bottom of the bracket 13 is equipped with a moving device 16 with braking function. The water tank 8 is installed on the moving device 16, which can move the device together with the water tank 8 to the required location.

[0084] The support frame 13 is made of a telescopic rod with telescopic function. The height of the support frame 13 is 1 meter to 10 meters, and it can be raised to a maximum height of 10 meters.

[0085] The above effectively solves the problem of quickly dispelling cold air or raising the air temperature when it first arrives and the air temperature is not yet very low, thus achieving a good anti-frost and antifreeze effect without causing unnecessary waste. It also achieves the function of delivering high heat for anti-frost and antifreeze when the air temperature is low. Integrating these two functions avoids the problem of separate manufacturing, which would be too costly and put pressure on businesses. It also saves labor costs and prevents heat waste.
