Description

Technical Field

[0001] This invention belongs to the field of orchard frost disaster protection technology, specifically relating to a frost protection device for fruit trees during flowering period with slow heat release and smoke emission function. Background Technology

[0002] Frost during the flowering period is one of the main causes of reduced orchard yields, and in severe cases, it can even lead to total crop failure. This is especially true in Northwest China, such as Gansu and Ningxia, where large orchard areas have been frequently affected by late spring frosts in recent decades, resulting in extremely serious economic losses. Traditionally, frost prevention methods involve setting up firewood piles in the orchard to improve temperature through smoke. Compared to other protective measures, such as spraying antifreeze, smoke fumigation is a continuous process and currently the best technological choice. However, the most severe frost occurs in the last few hours from late night to dawn, and the limited burning time of the firewood used for smoke fumigation poses a safety hazard of easily igniting open flames. The most serious problem is the significant environmental pollution caused by smoke fumigation, and the state has explicitly prohibited the burning of firewood in the fields. Therefore, new technologies are urgently needed to supplement orchard frost prevention measures and methods.

[0003] In existing technologies, some use electric heating devices for frost prevention. However, this method suffers from limitations: low-power devices are insufficient to achieve the desired effect, while high-power devices cannot be supplied in sufficient quantities, resulting in high costs and unresolved electricity issues. To address these shortcomings, those skilled in the art have proposed utilizing lime, which releases heat upon contact with water, to design frost prevention measures. Using lime for frost prevention is not only cost-effective but also releases a considerable amount of heat. However, existing technologies lack effective measures and methods, primarily addressing two issues: first, how to limit the protective measures to ensure the heat release range; and second, how to maintain heat release for several hours of frost. Therefore, the technology remains difficult to operate and lacks maturity.

[0004] For example, the patent application titled "A Frost Protection Device for Mountain Apples" (publication number CN121153520A) discloses "a three-dimensional frost protection system that combines a reciprocating oscillating wind turbine with a self-heating chemical packing chamber to create a synergistic effect of wind disturbance and chemical heat release. This device automatically activates when frost occurs. The wind turbine, driven by the reciprocating rotating turbine, oscillates at a large angle, effectively stirring up the stable air in the orchard and disrupting the near-ground inversion layer structure. Simultaneously, the heat-releasing packing chamber continuously releases heat through the chemical reaction of the composite packing, forming a localized heat source. The heat-releasing packing chamber is filled with quicklime and chlorinated..." The composite filler, a mixture of calcium and activated carbon in a specific ratio and pressed, can trigger and maintain an exothermic reaction in humid air through the rapid adsorption of moisture by the activated carbon. The pressing process ensures a slow, long-lasting, and dust-free reaction. Combined with the ventilation holes on the side walls of the chamber, it achieves controllable and long-term heat release. However, this "exothermic filler chamber" in Northwest China cannot effectively contribute to frost protection for two reasons: firstly, the "exothermic filler chamber" is placed statically on the orchard ground without any active external operation measures; secondly, the air in Northwest China is relatively dry, and the moisture in the air cannot react with the lime raw materials in the "exothermic filler chamber" to release heat. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of serious pollution and poor effectiveness of existing orchard frost prevention measures and devices. It provides a fruit tree flowering period frost prevention device that utilizes the heat released by the slaking reaction of quicklime raw materials and has the function of slow heat release and smoke emission.

[0007] Furthermore, a bearing seat is fixedly installed on the base plate of the bracket, and a cylindrical roller bearing is installed in the bearing seat; the rotating base includes a base plate, a transmission gear ring and a rotating shaft. The base plate has a circular structure, the transmission gear ring is arranged along the inner side of the bottom of the base plate, and the rotating shaft is arranged along the center of the bottom of the plate; the rotating base is installed on the bearing seat of the base plate through the rotating shaft, and is installed in a transmission engagement with the transmission device through the transmission gear ring.

[0008] Furthermore, the base plate of the rotating base is evenly provided with insertion holes, and baffles are installed in the insertion holes; the insertion holes are symmetrically arranged along the center position of the base plate and are located on the outside of the reaction chamber placement position. The baffles are installed to fix the reaction chamber and prevent the reaction chamber from radially shifting during the operation of the rotating base.

[0009] Furthermore, the reaction chamber includes a chamber cylinder and a chamber cover, with the chamber cover installed at the upper end of the chamber cylinder; the chamber cylinder is provided with an exhaust pipe along its side wall; a universal anti-winding connector is fixedly installed on the chamber cover; both joints of the universal anti-winding connector adopt a universal ball valve structure, with the upper joint connected to a water supply tank and the lower joint equipped with a water spraying device.

[0010] Furthermore, the water supply tank is an insulated and antifreeze water tank with a water inlet at the top and a water outlet at the bottom. An electronic control valve is installed on the water outlet, and a water supply pipe is connected to the water outlet. The water supply pipe is connected to the upper end of a universal anti-tangle connector.

[0011] Furthermore, the transmission device includes a power gear, a reducer, a motor, and a battery; the reducer, motor, and battery are fixedly mounted on the base plate, the battery powers the motor, the power gear is mounted on the output shaft of the reducer, and the motor output shaft and the reducer input shaft are fixedly connected by a coupling; the transmission device is installed by the power gear meshing with the transmission gear ring of the rotating base.

[0012] Furthermore, the sprinkler device includes a nozzle support and nozzles. The nozzle support is provided with a water inlet interface, and the nozzles are evenly distributed and installed along the pipe body. The nozzle support is installed on the lower end of the universal anti-tangle joint through the water inlet interface.

[0013] Furthermore, a water tank fixing bracket is provided around the top of the bracket, and a water pipe hanger is provided at the center of the bottom of the bracket; the water pipe hanger is used to install the water pipe of the water supply tank.

[0015] Furthermore, the base plate is provided with feet at its four bottom corners.

[0016] The beneficial effects of this invention are as follows: 1.

[0019] 4. This invention solves the problems of uniform water spraying inside the reaction chamber and water supply pipe entanglement during the rotation of the chamber by using universal anti-winding joints and water spraying devices installed on the reaction chamber and chamber cover.

In addition, the water supply pipe joints do not rotate with the reaction chamber, thus avoiding the phenomenon of water supply pipe entanglement.

[0020] 5. This invention utilizes an electronic control valve installed on the outlet of the water supply tank, employing existing technologies such as circulating control electric valves or intelligent timed solenoid valves, to control the intermittent water supply within the reaction chamber, thereby achieving a stable heat supply effect by controlling the continuous reaction and release of heat from quicklime.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1 Refer to the instruction manual. Figure 1 The invention shown is a fruit tree flowering period frost prevention device with slow-release heat and smoke function, comprising a support 1, a rotating base 2, a reaction chamber 4, a water supply tank 5, and a transmission device 6; the support 1 is fixedly provided with a base plate 11 and a top frame 13; the rotating base 2 and the transmission device 6 are configured and installed on the base plate 11, and the transmission device 6 is installed in a transmission cooperation with the rotating base 2; the reaction chamber 4 is configured and installed on the rotating base 2, and the reaction chamber 4 is provided with a water spraying device 44; the water supply tank 5 is fixedly installed on the top frame 13 of the support 1, and the water supply tank 5 is connected to the water spraying device 44 of the reaction chamber 4 for water supply.

[0030] This device loads quicklime into reaction chamber 4 and supplies water to reaction chamber 4 using water supply tank 5, causing the quicklime to undergo a slaking reaction that releases heat. Then, the rotating base 2 drives reaction chamber 4 to rotate, distributing the heat released by the reaction evenly to the surrounding area. This achieves the effect and purpose of using the heat released by the slaking reaction of quicklime to carry out frost protection operations in orchards. The frost protection effect is obvious and the process is clean and pollution-free.

[0031] Example 2 Refer to the instruction manual. Figure 1-7 As shown, based on Example 1, the present invention provides a rotating functional structure for a fruit tree flowering period frost prevention device with slow-release heat and smoke function.

[0032] A bearing seat 12 is fixedly installed on the base plate 11 of the support 1, and a cylindrical roller bearing is installed in the bearing seat 12. The rotating base 2 includes a seat plate 21, a transmission gear ring 22, and a rotating shaft 23. The seat plate 21 has a circular structure and is provided with a transmission gear ring 22 that is in transmission cooperation with the transmission device 6. A rotating shaft 23 for rotation is provided along the center of the bottom of the plate. The rotating base 2 is mounted on the bearing seat 12 of the base plate 11 via the rotating shaft 23. Insertion holes 211 are evenly distributed on the seat plate 21 of the rotating base 2, and baffles 3 are installed in the insertion holes 211. The insertion holes 211 are symmetrically distributed along the center of the seat plate 21 and are located outside the placement position of the reaction chamber 4. The baffles 3 are installed to fix the reaction chamber 4 and prevent the reaction chamber 4 from shifting during the operation of the rotating base 2. The transmission device 6 includes a power gear 61, a reducer 62, a motor 63, and a battery 64. The reducer 62, the motor 63, and the battery 64 are fixedly mounted on the base plate 11. The power gear 61 is mounted on the output shaft of the reducer 62. The output shaft of the motor 63 is fixedly connected to the input shaft of the reducer 62 via a coupling. The power gear 61 of the transmission device 6 is meshed with the transmission gear ring 22 of the rotating base 2.

[0033] This device achieves rotational dynamic balance by configuring a rotating shaft 23 on a circular base plate 21 and utilizing a bearing housing 12, thus maintaining the rotation of the rotating base 2 with a relatively small torque. To ensure stable transmission of the rotating base 2, the device employs a gear transmission mechanism in the transmission device 6. Utilizing the high transmission ratio between the reducer 62 and the transmission gear ring 22 and the power gear 61, the device reduces the power requirement for driving the base plate 21. A small-sized DC motor can drive the operation, requiring only a small-sized battery 64 to solve the power problem. The device is simple to manufacture, low in cost, and easy to mass-produce and use.

[0034] Example 3 Refer to the instruction manual. Figure 1-2 As shown in Figures 8 and 9, based on Example 1, this invention provides a reaction chamber water supply structure and method for a fruit tree flowering period frost prevention device with slow-release heat and smoke function.

[0035] The reaction chamber 4 includes a chamber cylinder 41 and a chamber cover 42, with the chamber cover 42 installed at the upper end of the chamber cylinder 41. An exhaust pipe 411 is provided along the side wall of the chamber cylinder 41. A universal anti-winding connector 43 is fixedly installed on the chamber cover 42. Both joints of the universal anti-winding connector 43 adopt a universal ball valve structure; the upper joint is connected to the water supply pipe 54 of the water supply tank 5, and the lower joint is equipped with a sprinkler device 44. The sprinkler device 44 includes a nozzle support 441 and nozzles 442. The nozzle support 441 is provided with a water inlet interface, and the nozzles 442 are evenly distributed along the pipe body. The nozzle support 441 is installed on the lower joint of the universal anti-winding connector 43 through the water inlet interface. The water supply tank 5 is an insulated and freeze-proof water tank with a water inlet 51 at the top and a water outlet 52 at the bottom. An electronic control valve 53 is installed on the water outlet 52, and a water supply pipe 54 is connected to the water outlet 52. The other end of the water supply pipe 54 is connected to the upper connector of a universal anti-winding connector 43. A water tank fixing bracket 131 is installed around the top of the bracket 1's top frame 13, and a water pipe hanger 132 is installed at the center of the bottom of the top frame 13. The electronic control valve 53 is a circulating control electric valve or an intelligent timed solenoid valve, and is powered by a self-contained battery or a connected battery 64.

[0036] In this embodiment, during the rotation of the reaction chamber 4, the universal anti-winding connector 43 rotates with the entire reaction chamber 4. The water supply pipe 54 connected to the upper connector of the universal anti-winding connector 43 does not rotate with the universal anti-winding connector 43, maintaining a fixed connection posture and avoiding entanglement. The water supply pipe 54 can be directly connected to the upper connector of the universal anti-winding connector 43 from above the chamber cover 42 via the water pipe hanger 132, avoiding contact between the water supply pipe 54 and other parts of the reaction chamber 4. The water spraying device 44 installed at the lower connector of the universal anti-winding connector 43 will not rotate synchronously with the universal anti-winding connector 43 due to inertia. Therefore, the water spraying position of the nozzle 442 inside the reaction chamber 4 can be changed, making it constantly changing during the water supply process.

[0037] This embodiment of the invention employs an intermittent water supply method, by controlling 5 pairs of water supply tanks. The water supply and timing in reaction chamber 4 are controlled to regulate the continuous reaction of quicklime within it. The electronic control valve 53 installed on the outlet 52 of the water supply tank 5 adopts the existing technology of a circulating control electric valve or an intelligent timed solenoid valve. After the opening and closing time cycle is set, the periodic intermittent circulating water supply can be completed after starting, thereby achieving the heating effect of controlling the continuous reaction and stable heat release of quicklime.

[0038] Example 4 Refer to the instruction manual. Figure 1-9The frost protection device for fruit trees during flowering period with slow-release heat and smoke function, as described in Examples 1-3 of the present invention, operates as follows: 1. Distribute the device of this invention evenly in the orchard. Fill the silo 41 with a sufficient amount of quicklime powder (the state of the quicklime raw material is not critical; using powder or granules is more conducive to the reaction). Install the silo cover 42 on the silo 41. Then place the reaction chamber 4 on the base plate 21 of the rotating base 2, positioned along the center. Finally, install the baffle 3 in the insertion hole 211 of the base plate 21 to fix the silo 41. After installing the reaction chamber 4, connect the water supply pipe 54 of the water supply tank 5 to the upper end of the universal anti-winding connector 43 of the silo cover 42 to form a water supply pipeline. Fill the water supply tank 5 with a sufficient amount of water to complete the preparation work.

[0039] 2. The intermittent opening and closing time cycle of the electronic control valve 53 on the water supply tank 5 is pre-set, automatically opening for 20 seconds every 10 minutes. The electronic control valve 53 adopts the existing intermittent automatic opening and closing electronic controller valve body, powered by its own battery. After the switch is turned on, it automatically performs the periodic opening and closing operation of the valve body.

[0040] 3. Based on the frost protection operation time, the motor 63 of the transmission device 6 is turned on periodically. The motor 63 is a low-power DC motor powered by a battery 64. After being reduced in speed by a reducer 62, the motor 63 drives the power gear 61. Finally, the meshing of the power gear 61 with the transmission gear ring 22 on the rotating base 2 drives the rotating base 2 to rotate. The rotating base 2 is mounted on the bearing seat 12 of the base plate 11 via a rotating shaft 23. The bearing structure forms a stable rotating base structure. The power gear 61 and the transmission gear ring 22 have a high transmission ratio structure, and only a very low torque is needed to rotate the rotating base 2.

[0041] 4. Open the electronic control valve 53 to supply water to the sprinkler device 44 in the reaction chamber 4 through the water supply pipe 54. The sprinkler device 44 sprays water onto the quicklime in the chamber 41 through the nozzles 442 on the nozzle bracket 441. Upon contact with water, the quicklime in the chamber 41 begins a slaking reaction, releasing heat and instantly generating a large amount of high-temperature steam. The high-temperature steam expands inside the chamber 41 and is quickly discharged from the exhaust pipe 411. The electronic control valve 53 controls the valve body to open for 20 seconds and then close, then reopens after a 10-minute interval. This 20-second water supply is just enough to meet the 10-minute vigorous reaction of the quicklime in the chamber 41.

[0042] 5. As the rotating base 2 rotates, the reaction chamber 4, which is fixed on the base plate 21, rotates synchronously. Through the high transmission ratio between the power gear 61 and the transmission gear ring 22, the rotation speed of the rotating base 2 is controlled to be 10-20 revolutions per minute. The exhaust pipe 411 on the chamber 41 continuously dissipates hot air to the surroundings in a 360-degree manner during rotation, achieving the technical effect of uniform heat dissipation to all directions.

[0043] 6. During the rotation of the reaction chamber 4, the chamber cover 42 rotates together with the chamber cylinder 41. The universal anti-winding connector 43, which is fixedly installed on the chamber cover 42, has universal ball valve structure at both the upper and lower inlet and outlet. The upper universal ball valve structure is connected to the water supply pipe 54 of the water supply tank 5, which can prevent the water supply pipe 54 from rotating and winding with the universal anti-winding connector 43. The nozzle support 441 installed on the lower universal ball valve structure is subjected to centrifugal force when the universal anti-winding connector 43 rotates, which can produce a relative rotation effect, so that the nozzle 442 sprays water evenly.

[0044] 7. Once the natural temperature rises and frost prevention work ceases, or once the quicklime in reaction chamber 4 no longer produces high-temperature flue gas, simultaneously close the electronic control valve 53 and transmission device 6, stop water supply, and stop the rotation of the rotating base 2. Disconnect the water supply pipe 54 from the universal anti-winding connector 43, remove the baffle 3 fixing the chamber 41 from the insertion hole 211 on the base plate 21, lift the reaction chamber 4 off the base plate 21, transport it to the cleaning position, open the chamber cover 42, pour out the quicklime material in the chamber 41, clean the chamber 41, refill with quicklime raw materials, and it can be put back into use.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
