Description

Technical Field

[0001] This invention belongs to the field of greenhouse technology, specifically a multi-protection greenhouse and protection method for planting and growing cherry trees. Background Technology

[0002] With the continuous development of planting technology and the increasing demand for refined management, the control of the planting environment has become increasingly critical. Multi-protection greenhouses for cherry tree planting and growth have emerged to create a stable and suitable growing environment for cherry trees, effectively resist adverse weather, strictly control pests and diseases, precisely optimize light, and comprehensively help cherry trees grow vigorously, ensuring high yield and quality of cherries.

[0003] Chinese patent application number 202411306056.X discloses a ventilation device and method for vegetable greenhouses, including a foundation, a main body of the greenhouse fixedly installed on the top of the foundation, a comprehensive cleaning device connected to the side of the main body of the greenhouse, a wind-powered conveying mechanism on the inner side of the comprehensive cleaning device, an installation shell on the outer side of the wind-powered conveying mechanism, a wind direction adjustment mechanism on one side of the wind direction adjustment mechanism, a dust cleaning mechanism on one side of the dust cleaning mechanism, a convenient disassembly and assembly mechanism on one side of the dust cleaning mechanism, an energy-saving device installed on the top of the main body of the greenhouse, and a heating device on the outer side of the main body of the greenhouse. Although this greenhouse has adaptively adjusted the wind direction of the ventilation device, it overlooks the fact that continuously introducing air with different humidity levels from the outside into the greenhouse will disrupt the originally stable humidity balance inside the greenhouse, adversely affecting the stability of the greenhouse environment.

[0004] In addition, when there is a large temperature difference between the inside and outside of the multi-proof greenhouse, such as in winter when the multi-proof greenhouse is equipped with heating equipment, the temperature inside the greenhouse is high, which creates a large temperature difference with the cold outside temperature. This can easily cause condensation on the inside of the roof, reduce sunlight transmittance, and affect the photosynthesis of the cherry trees.

[0005] Meanwhile, heavy snowfall caused the outer side of the canopy to be covered with snow, resulting in the canopy sinking and deforming, which in turn affected the structural stability of the canopy and prevented it from playing its due protective role. Summary of the Invention

[0006] To address the above problems, this invention provides a multi-protection shed and protection method for planting and growing sweet cherry trees, thereby solving the problems mentioned in the background art.

[0009] The cleaning assembly includes a scraper with a pressure sensor. The scraper has a hollow structure and water collection grooves are connected to both sides of the scraper. Multiple jet components are evenly arranged on the side wall of the scraper. Each jet component includes an air storage chamber, the side wall of which is connected to the side wall of the scraper.

[0011] The bottom of the box is provided with multiple horizontal beams, and the two ends of the horizontal beams are fixedly connected to the longitudinal beams. The two ends of the longitudinal beams are fixedly connected to the columns.

[0012] Preferably, the carrier assembly includes a top beam, on which multiple U-shaped frames are connected. The ends of the multiple U-shaped frames away from the top beam are fixedly connected to a main beam. Multiple inclined beams are connected to both ends of the top beam. The ends of the inclined beams away from the top beam are fixedly connected to the main beam. Multiple secondary beams are evenly arranged between the inclined beams. One end of each secondary beam is fixedly connected to the top beam, and the other end is fixedly connected to the main beam. A canopy is connected to both sides of the secondary beams. The bottom of the canopy abuts against the top of the scraper.

[0013] Preferably, the humidification chamber is equipped with a heating pipe inside, and water supply pipes are connected to the side walls on both sides of the humidification chamber. The end of the water supply pipe away from the humidification chamber is connected to a water supply device, which is connected to a crossbeam. The end of the water supply device away from the water supply pipe is connected to a return water pipe, and the end of the return water pipe away from the water supply device is connected to a drain trough.

[0014] Preferably, the working chamber is connected to a ventilation chamber on the side wall near the louver, a cooling pipe is provided inside the working chamber on the side near the ventilation chamber, an exhaust fan is provided inside the ventilation chamber, a humidity sensor is provided on the exhaust fan, and the end of the ventilation chamber away from the exhaust fan is fixedly connected to the louver.

[0015] The top of the working chamber is connected to two hoses. The end of the hose away from the working chamber is connected to the inner bottom of the scraper. The hose is equipped with a venting solenoid valve. Multiple docking holes are opened on the side wall of the working chamber away from the ventilation chamber.

[0016] Preferably, two limiting plates are fixedly connected to both ends of the side wall of the scraper, and a roller is rotatably connected between the two limiting plates. One end of the roller passes through the limiting plate and is connected to a rotating motor. A track is provided on one side of the roller, and both ends of the track are fixedly connected to the inclined beam. The roller and the track abut against each other. A groove is provided on the scraper, and the groove matches the track.

[0017] Preferably, the nozzle has multiple vent holes on its side wall, and a return spring is fixedly connected to the bottom of the nozzle. The end of the return spring away from the nozzle is fixedly connected to the bottom of the air storage chamber.

[0018] This invention also provides a method for protecting cherry trees with multiple protective structures, comprising the following steps:

[0019] Step 1: When the ambient air humidity is greater than the preset humidity value, activate the cooling coil to reduce the air humidity; when the ambient air humidity is less than the preset humidity value, activate the heating coil to increase the air humidity.

[0020] Step 2: Control the scraper to move back and forth along the track to scrape away the condensation in the ceiling. The condensation passes through the water collection tank, drainage tank and return water pipe in sequence and enters the water supply equipment.

[0021] Step 3: When the nozzle begins to contact the recessed area of ​​the ceiling, the reset spring is compressed, and the signal is transmitted to the central control module, which then controls the ventilation regulating valve to open.

[0022] Step 4: As the nozzle moves along the surface path of the recessed area, the wind force of the pulsed hot air is adaptively adjusted, while the scraper causes the snow, ice, and liquid water on the ceiling to vibrate up and down.

[0023] Compared with the prior art, the beneficial effects of this application are as follows:

[0024] 1. This invention utilizes the coordinated operation of components such as adjustment, cleaning, and jetting to detect the roof's depression and deformation using the compression of a return spring and the pressure on the scraper. The nozzles adaptively adjust the pulsed hot air force based on the deformation, preventing significant fluctuations in air humidity in smaller depressions and enhancing the melting and cleaning effect on larger depressions. Simultaneously, the scraper causes the snow, ice, and liquid water on the roof to vibrate up and down, gradually reducing their adhesion to the roof. Furthermore, during different stages of the snow melting operation, the rotation speed of the rotating motor and the power of the heating element are adjusted accordingly to thoroughly clean the snow on the roof at different stages, effectively solving the potential hazards of snow accumulation.

[0025] 2. This invention, through the coordinated operation of components such as heating pipes, cooling pipes, and humidity sensors, ensures that when the humidity of the outside air is greater than a preset humidity value, the cooling pipes are activated to reduce the air humidity; when the humidity of the outside air is less than the preset humidity value, the heating pipes are activated to increase the air humidity. This effectively ensures that the air humidity inside the multi-protection greenhouse is always maintained within the preset humidity range, creating a more suitable growing environment for the cherry trees inside the multi-protection greenhouse.

[0026] 3. This invention, through the coordinated arrangement of components such as scrapers, drainage channels, and return water pipes, effectively removes condensation from the canopy during its back-and-forth movement, solving the problem of condensation reducing the photosynthesis of cherry trees. At the same time, a large amount of condensation gathers in the drainage channel, flows along the return water pipe, and finally enters the water supply equipment, realizing the resource cycle of condensation recycling and reuse.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1: As Figures 1-2As shown, this embodiment discloses a multi-protection shed for planting and growing cherry trees, including a support component 1, which can provide stable support for the multi-protection shed. The support component 1 is equipped with an adjustment component 2 for controlling the humidity of the gas entering the multi-protection shed. A carrier component 3 is fixedly connected to the support component 1. The carrier component 3 can block the cherry trees from the harsh weather outside. The carrier component 3 is equipped with two cleaning components 4 inside, which can promptly scrape off the condensation attached to the inside of the canopy 305.

[0044] Furthermore, such as Figures 3-4 As shown, the support component 1 includes a base plate 101, which is made of concrete to prevent uneven settlement of the multiple protective sheds. A water-retaining wall 102 is provided on the base plate 101 to prevent rainwater backflow. An access door 103 for easy passage of staff is connected to the water-retaining wall 102. Multiple columns 104 are evenly provided on the top of the water-retaining wall 102. Side sheds 105 are connected between adjacent columns 104. The side sheds 105 serve as isolation to reduce environmental interference from external factors. A louvered fan 110 to promote air circulation is provided on the side of the side shed 105 away from the access door 103. A main beam 106 is fixedly connected to the end of the column 104 away from the water-retaining wall 102. The construction of the column 104 and the main beam 106 forms a stable structural frame for the multiple protective sheds.

[0045] Furthermore, such as Figures 5-6 As shown, the carrier component 3 includes a top beam 301, on which multiple U-shaped frames 302 are connected. The ends of the multiple U-shaped frames 302 away from the top beam 301 are fixedly connected to the main beam 106. Multiple inclined beams 303 are connected to both ends of the top beam 301. The ends of the inclined beams 303 away from the top beam 301 are fixedly connected to the main beam 106. Multiple secondary beams 304 are evenly arranged between the inclined beams 303. One end of the multiple secondary beams 304 is fixedly connected to the top beam 301, and the other end is fixedly connected to the main beam 106. A canopy 305 for resisting external natural hazards is connected to both sides of the secondary beams 304. The construction of the top beam 301, inclined beams 303 and secondary beams 304 ensures the structural stability of the canopy 305.

[0046] Multi-proof sheds often use exhaust fans 210 to introduce outside air into the shed for continuous ventilation. However, the humidity of the outside air is complex and can interfere with the humidity balance inside the shed. Therefore, the adjustment component 2 includes a housing 201, which can protect the internal components. Multiple crossbeams 108 are evenly arranged at the bottom of the housing 201. Longitudinal beams 109 are fixedly connected to both ends of the crossbeams 108, and both ends of the longitudinal beams 109 are fixedly connected to the columns 104. The crossbeams 108 and longitudinal beams 109 work together to provide a working platform for the housing 201 and the water supply equipment 207. Figures 7-8As shown, the interior of the housing 201 is provided with a working chamber 202 and a humidifying chamber 203. The working chamber 202 is designed to facilitate the humidity regulation of the outside air. The humidifying chamber 203 is provided with a heating pipe 213. Water supply pipes 206 are connected to the side walls on both sides of the humidifying chamber 203. The end of the water supply pipe 206 away from the humidifying chamber 203 is connected to a water supply device 207. The water supply device 207 is connected to the crossbeam 108 and provides a continuous water source for the humidifying chamber 203. The heating pipe 213 quickly heats the water. A fixing plate 204 is connected between the working chamber 202 and the humidifying chamber 203. Multiple connecting holes 205 are evenly opened on the fixing plate 204. The water vapor generated by the humidifying chamber 203 passes through the connecting holes 205 and mixes with the outside air, thereby increasing the air humidity. The working chamber 202 has a ventilation chamber 209 connected to the side wall near the louvered fan 110. The inside of the working chamber 202, near the ventilation chamber 209, is equipped with a refrigeration pipe 214 for condensing humid air. The ventilation chamber 209 is equipped with an exhaust fan 210. When the exhaust fan 210 is turned on, it can introduce fresh air from the outside. The exhaust fan 210 is equipped with a humidity sensor to detect the humidity of the fresh air from the outside. The end of the ventilation chamber 209 away from the exhaust fan 210 is fixedly connected to the louvered fan 110. Multiple docking holes 212 are opened on the side wall of the working chamber 202 away from the ventilation chamber 209. After the humidity of the introduced air is processed, the air enters the interior of the multi-layer canopy through the docking holes 212 to achieve air circulation. When in use, the cooling pipe 214 is activated to liquefy water vapor in the humid air into water droplets, thereby reducing the humidity of the air; the heating pipe 213 is activated to heat the water in the humidification chamber 203, generating water vapor, thereby increasing the humidity of the air and keeping the air humidity in the multi-proof shed within the preset humidity range.

[0047] In winter, condensation easily forms on the inner side of the 305mm canopy roof, reducing sunlight transmittance and further... Figures 9-11 , Figure 14As shown, the cleaning component 4 includes a scraper 401. The top of the scraper 401 abuts against the bottom of the ceiling 305. As the scraper 401 moves back and forth, it can scrape off the condensation on the ceiling 305. Water collection troughs 402 for collecting condensation are connected to both sides of the scraper 401. A drainage trough 107 is fixedly connected to the side wall of the main beam 106. The top of the drainage trough 107 abuts against the bottom of the water collection trough 402. The condensation in the water collection trough 402 enters the drainage trough 107 under the action of gravity. The end of the water supply device 207 away from the water supply pipe 206 is connected to a return water pipe 208. The end of the return water pipe 208 away from the water supply device 207 is connected to the drainage trough 107. The condensation collected in the drainage trough 107 flows along the return water pipe 208 and enters the water supply device 207, realizing the resource cycle of condensation recycling and reuse. Two limiting plates 404 are fixedly connected to both ends of the side wall of the scraper 401. The movement of the limiting plates 404 can drive the scraper 401 to move synchronously. A roller 405 is rotatably connected between the two limiting plates 404. One end of the roller 405 passes through the limiting plate 404 and is connected to a rotating motor 406. A track 407 is provided on one side of the roller 405. The two ends of the track 407 are fixedly connected to the inclined beam 303. The roller 405 and the track 407 abut against each other. A groove is opened on the scraper 401, and the groove matches the track 407. In use, the roller 405 rotates along the track 407, thereby driving the scraper 401 to scrape off the condensation, solving the problem of condensation inside the canopy 305 reducing the photosynthesis of the cherry trees.

[0048] The working principle of this invention is as follows: Multiple ventilation sheds are connected to a central control module. The central control module controls the exhaust fan 210 to start, causing the exhaust fan 210 to rotate and rapidly circulate fresh outside air. The outside air passes sequentially through the louvered fan 110 and the ventilation chamber 209. At this time, the humidity sensor detects the humidity of the outside air and transmits this humidity value to the central control module. The central control module determines whether the humidity of the outside air meets the preset humidity value. When the humidity of the outside air is greater than the preset humidity value, for example, in summer when the surface water evaporates quickly, causing a significant increase in air humidity, the cooling pipe 214 is activated. When the humid air passes through the cooling pipe 214, the water vapor in the humid air can quickly condense into water droplets. The water droplets adhere to the surface of the cooling pipe 214 and then flow into the interior of the humidification chamber 203. The air, after being dehumidified by condensation, enters the working chamber 202 and then enters the multi-protection shed through the docking hole 212. Similarly, when the humidity of the outside air is lower than the preset humidity value, such as when the evaporation rate of surface water decreases sharply in winter, causing a significant drop in air humidity, the heating pipe 213 is activated. The heating pipe 213 heats the water in the humidification chamber 203 to generate water vapor. The water vapor enters the working chamber 202 through the connecting hole 205 and mixes with the air. The air, after being evaporated and humidified, then enters the multi-protection shed through the docking hole 212, thereby effectively ensuring that the air humidity inside the multi-protection shed is always maintained within the preset humidity range, creating a more suitable growing environment for the cherry trees inside the multi-protection shed.

[0049] It should be noted that while using the cooling pipe 214 to reduce air humidity, the air temperature also decreases simultaneously, which helps the multi-protection greenhouse maintain temperature balance in summer; while using the heating pipe 213 to increase air humidity, the air temperature also increases simultaneously, which helps the multi-protection greenhouse maintain temperature balance in winter, effectively mitigating the adverse effects of external temperature on cherry trees.

[0050] When staff observe a significant amount of condensation adhering to the inner side of the canopy 305, the central control module controls the rotating motor 406 to rotate at a set speed. The rotating motor 406 drives the roller 405 to rotate along the track 407, thereby moving the limit plate 404 along the track 407. Because the top of the scraper 401 abuts against the bottom of the canopy 305, the scraper 401 effectively removes the condensation inside the canopy 305 during its back-and-forth movement, solving the problem of condensation reducing the photosynthesis of the cherry trees. The scraped condensation, guided by the scraper 401, slowly flows into the water collection troughs 402 on both sides. Then, under gravity, the condensation in the water collection troughs 402 enters the drainage trough 107. A large amount of condensation then accumulates in the drainage trough 107, flowing along the return water pipe 208 and finally entering the water supply equipment 207, achieving a resource cycle of condensation recycling and reuse.

[0051] Example 2: The roof 305 of a multi-protection canopy is typically made of plastic film. Plastic film has poor rigidity and is prone to denting and deformation under external pressure. After snowfall, a large amount of snow accumulates on the roof 305, causing it to dent and deform. Simultaneously, due to the high temperature inside the multi-protection canopy, the snow in contact with the roof 305 absorbs heat and melts into water, which then freezes into ice at low temperatures (similar to the formation of icicles on roof eaves). Ice has strong adhesion, exerting even greater pressure on the roof 305, further exacerbating its denting and deformation. At this point, the roof 305 exhibits a shape that is lower in the middle and higher around the edges, thus affecting the structural stability of the multi-protection canopy and potentially leading to structural damage, rendering it unable to perform its intended protective function. Therefore, Example 2 is proposed to address the above problems.

[0052] like Figures 7-8 As shown, the top of the working chamber 202 is connected to two hoses 211. The end of the hose 211 away from the working chamber 202 is connected to the inner bottom of the scraper 401. The scraper 401 has a hollow structure. The hose 211 is equipped with a venting solenoid valve. By controlling the venting solenoid valve to open, the air in the working chamber 202 can enter the scraper 401 through the hose 211. The movement of the cleaning component 4 will cause the hose 211 to move along the path of multiple U-shaped frames 302 to prevent the hose 211 from colliding with the cherry tree.

[0053] Furthermore, such as Figures 9-14 As shown, a pressure sensor is provided on the scraper 401 to detect the pressure on the top of the scraper 401. Multiple jet assemblies 403 are evenly distributed on the side wall of the scraper 401, and these jet assemblies 403 can eject air from the working chamber 202. Each jet assembly 403 includes an air storage chamber 4031, which is used to transfer air from the working chamber 202. The side wall of the air storage chamber 4031 is connected to the side wall of the scraper 401. A movable chamber 4032 is connected to the air storage chamber 4031. A nozzle 4033 is slidably connected within the movable chamber 4032, allowing it to slide within the chamber. The top of the nozzle 4033 is close to the ceiling 305. Multiple vent holes 4034 are provided on the side wall of the nozzle 4033, and a composite [unclear - possibly a device or component] is fixedly connected to the bottom of the nozzle 4033. The return spring 4035 has one end away from the nozzle 4033 and is fixedly connected to the bottom of the air storage chamber 4031. When the return spring 4035 is compressed, the nozzle 4033 moves towards the air storage chamber 4031. The side wall of the movable chamber 4032 no longer blocks the vent hole 4034. At this time, the air in the air storage chamber 4031 enters the nozzle 4033 through the vent hole 4034. The air ejected from adjacent nozzles 4033 is connected to each other, thus forming a complete air jet area, which effectively improves the snow removal effect on the roof 305.

[0054] In snowy weather, when the humidity of the outside air is lower than the preset humidity value, the central control module controls the heating tube 213 to start. The heating tube 213 heats the water in the humidification chamber 203 to generate water vapor. The water vapor mixes with the outside air to form humidified hot air, which enters the multi-proof shed through the docking hole 212.

[0055] In the initial stage, the snow in contact with the ceiling 305 absorbs heat and melts into water, which then freezes into ice under low temperature. This process continues, causing the indentation deformation of the ceiling 305 to gradually increase. The central control module controls the rotating motor 406 to rotate forward at a set speed. The rotating motor 406 drives the scraper 401 to move forward along the track 407. With the synchronous movement of the scraper 401 and the jet assembly 403, when the nozzle 4033 begins to contact the indented area of ​​the ceiling 305, the nozzle 4033 compresses the return spring 4035 and moves towards the air storage chamber 4031. After detecting the indentation deformation on the ceiling 305, the signal is transmitted to the central control module, which controls the ventilation regulating valve to open. Under the action of pressure difference, the hot air in the working chamber 202 flows rapidly along the hose 211 and enters the scraper 401 and the air storage chamber 4031.

[0056] As the nozzle 4033 descends along the surface path of the recessed area until it reaches the lowest point of the recessed area, the amount of blockage of the vent 4034 by the side wall of the active cavity 4032 gradually decreases, causing the volume of hot air passing through the vent 4034 per unit time to continuously increase. The hot air is then ejected from the nozzle 4033, efficiently heating the snow. Meanwhile, some hot air escapes from the tiny gap between the nozzle 4033 and the ceiling 305, connecting with the hot air escaping from adjacent nozzles 4033 to form a complete jet heating zone, further enhancing the heating effect on the snow. Similarly, as the nozzle 4033 rises from the lowest point of the path along the surface of the recessed area to the flat area of ​​the ceiling 305, the blockage of the ventilation hole 4034 by the side wall of the active cavity 4032 gradually increases, causing the volume of hot air passing through the ventilation hole 4034 per unit time to continuously decrease. This reduction in hot air volume prevents large fluctuations in humidity inside the shed and also reduces energy consumption. Subsequently, the central control module controls the rotating motor 406 to reverse at a set rate. The rotating motor 406 drives the scraper 401 to move backward along the track 407, completing one snow melting cycle. This snow melting cycle is then repeated continuously. The wind force exerted on the snow by the hot air continuously changes, achieving pulsed hot air melting of the snow in the recessed area of ​​the ceiling 305.

[0057] It should be noted that the scraper 401 has good flexibility and always maintains close contact with the ceiling 305. Based on this characteristic, when the scraper 401 moves to the recessed area, it deforms accordingly following the curve of the recessed area. Simultaneously, its continuous movement propels the snow, ice, and liquid water accumulated along its path upwards slightly. Once the scraper 401 leaves the recessed area, the previously lifted snow, ice, and liquid water, losing support, are pushed back onto the ceiling 305 under gravity. The scraper 401's reciprocating motion in the recessed area causes the snow, ice, and liquid water on the ceiling 305 to vibrate synchronously, gradually reducing their adhesion to the ceiling 305 and further enhancing the snow removal effect.

[0058] In the initial stage of snow melting operations, as the rotating motor 406 rotates forward, the nozzle 4033 will contact the roof 305 before the scraper 401. Since the snow melting capacity of the pulsed hot air in the initial stage is lower than the freezing capacity of the snow, when the nozzle 4033 passes the lowest point of the depression area, the compression of the return spring 4035 continues to increase. Based on the change in the compression of the return spring 4035, the depression condition on the roof 305 is detected, thereby controlling the rotation speed of the rotating motor 406 to increase, so that the snow and ice on the roof 305 are melted. The increased vibration enhances the snow-melting capacity during the initial forward rotation. However, during the reverse rotation of the motor 406, the scraper 401 contacts the ceiling 305 before the nozzle 4033. As the scraper 401 passes the lowest point of the depression, the pressure on it continuously increases. The pressure on the scraper 401 is used to detect the depression on the ceiling 305, thereby increasing the power of the heating element 213 and increasing the amount of hot air passing through the nozzle 4033 per unit time, thus enhancing the snow-melting capacity during the initial reverse rotation. Therefore, in each snow-melting cycle during the initial stage, the compression of the return spring 4035 and the pressure on the scraper 401 continuously increase. Correspondingly, adjusting the rotation speed of the motor 406 and increasing the power of the heating element 213 further enhances the snow-melting capacity during the initial stage.

[0059] As the snow continues to absorb heat, the snow melting capacity of the pulsed hot air gradually increases until the snow melting capacity of the pulsed hot air is equal to the freezing capacity of the snow. When the nozzle 4033 passes through the lowest point of the depression area, the compression of the return spring 4035 no longer changes, and when the scraper 401 passes through the lowest point of the depression area, the pressure on the scraper 401 no longer changes, and the snow melting stabilizes.

[0060] During the stable phase, the concave deformation of the roof 305 remains unchanged. In each snow melting cycle, the change trend of the amount of blockage in the vent 4034 remains consistent, and the rotation speed of the rotating motor 406 and the power of the heating tube 213 remain unchanged. After continuously receiving the heat transferred by the pulsed hot air, the snow on the roof 305 continuously absorbs heat energy until the snow melting capacity of the pulsed hot air is greater than the freezing capacity of the snow, and enters the snow melting rebound phase.

[0061] During the rebound phase, in each snow melting cycle, the ice on the roof 305 continuously absorbs heat and melts into liquid water under the continuous heat transfer. Under the combined action of gravity and scraper 401, the liquid water flows down the surface of the roof 305 and eventually leaves the roof 305, draining outside the multi-proof shed. When the rotating motor 406 rotates forward, the compression of the return spring 4035 continuously decreases, thereby controlling the rotation speed of the rotating motor 406 to decrease, which weakens the vibration of the snow and ice on the roof 305. Smaller vibrations can accurately gather a small amount of snow, preventing the snow from splashing and scattering due to excessive vibration, making the snow melting work more thorough. When the rotating motor 406 rotates in reverse, the pressure on the scraper 401 continuously decreases, thereby controlling the power of the heating tube 213 to decrease, reducing the amount of hot air passing through the nozzle 4033 per unit time, avoiding large fluctuations in the humidity of the air inside the shed, and effectively reducing energy consumption. As the compression of the return spring 4035 continues to decrease until it is completely restored to its initial state, the compression of all return springs 4035 is zero, and the pressure on the scraper 401 is also restored to its initial value. The central control module controls the ventilation regulating valve to close, and the rotating motor 406 stops rotating, completing the melting and cleaning of the snow and ensuring the safety and stability of the multi-proof canopy.

[0062] Furthermore, after the hot air is sprayed onto the canopy 305, it quickly liquefies into water droplets. The scraper 401 scrapes away the water droplets, and the water collection tank 402 recycles the water droplets. It should be noted that there is relatively little snow accumulation around the canopy 305, and the slight deformation at both ends of the scraper 401 will not affect the relative movement between the scraper 401 and the track 407.

[0063] During the above process, the compression of the return spring 4035 and the pressure on the scraper 401 are used to detect the dent deformation of the roof 305. The nozzle 4033 can adaptively adjust the wind force of the pulse hot air according to the dent deformation to avoid large fluctuations in air humidity in the smaller dent areas and enhance the melting and cleaning effect of snow in the larger dent areas. At the same time, the scraper 401 drives the snow, ice and liquid water on the roof 305 to vibrate up and down, so that the adhesion of the snow, ice and liquid water to the roof 305 gradually decreases. In addition, during different stages of the snow melting operation, the rotation speed of the rotating motor 406 and the power of the heating tube 213 are adjusted accordingly to complete the thorough cleaning of the snow on the roof 305 at different stages, effectively solving the potential hidden dangers of snow accumulation.

[0064] Example 3: This example discloses a multi-protection method for planting and growing sweet cherry trees, including the following steps:

[0065] Step 1: When the humidity of the outside air is greater than the preset humidity value, activate the cooling pipe 214 to reduce the humidity of the air; when the humidity of the outside air is less than the preset humidity value, activate the heating pipe 213 to increase the humidity of the air.

[0066] Step 2: Control the scraper 401 to move back and forth along the track 407 to scrape off the condensation in the ceiling 305. The condensation passes through the water collection tank 402, the drainage tank 107 and the return water pipe 208 in sequence and enters the water supply equipment 207.

[0067] Step 3: When the nozzle 4033 begins to contact the recessed area of ​​the ceiling 305, the return spring 4035 is compressed, and the signal is transmitted to the central control module, which then controls the ventilation regulating valve to open.

[0068] Step 4: When the nozzle 4033 moves along the surface path of the recessed area, it adaptively adjusts the wind force of the pulsed hot air, while the scraper 401 drives the snow, ice and liquid water on the ceiling 305 to vibrate up and down.
