Description

Technical Field

[0001] The invention belongs to the technical field of planting greenhouses, and in particular is a multi-protection greenhouse for planting and growing cherry trees and a protection method. Background Art

[0002] With the continuous development of planting technology and the increasing demand for refined management, the regulation of the planting environment has become increasingly critical. Multi-protection sheds for the planting and growth of big cherry trees have come into being. They aim to create a stable and suitable growth environment for big cherry trees, effectively resist adverse climate, strictly control diseases and pests, accurately optimize light, and help cherry trees thrive in all aspects to ensure high yield and high quality of cherries.

[0003] A Chinese patent application with application number 202411306056.X discloses a ventilation device and method for a vegetable growing greenhouse, comprising a foundation, a planting shed main body fixedly installed on the top of the foundation, a comprehensive cleaning device connected to the side of the planting shed main body, a wind conveying mechanism arranged on the inner side of the comprehensive cleaning device, a mounting shell arranged on the outer side of the wind conveying mechanism, a wind direction adjusting mechanism arranged on one side of the wind direction adjusting mechanism, a dust cleaning mechanism arranged on one side of the dust cleaning mechanism, a convenient disassembly and assembly mechanism arranged on one side of the dust cleaning mechanism, an energy-saving device installed on the top of the planting shed main body, and a warming device arranged on the outer side of the planting shed main body; although the planting greenhouse has adaptively adjusted the wind direction of the ventilation device, it ignores the fact that the continuous introduction of air with different humidity from the outside into the planting greenhouse will destroy the originally stable humidity balance inside the greenhouse, and have an adverse effect on the stability of the environment inside the greenhouse.

[0004] In addition, when there is a large temperature difference between the inside and outside of the multi-protection shed, for example, in winter when the multi-protection shed is equipped with heating equipment, the temperature inside the shed is higher, which forms a large temperature difference with the cold temperature outside. Condensation is easily produced on the inside of the ceiling, reducing the sunlight transmittance and affecting the photosynthesis of the cherry tree.

[0005] At the same time, heavy snow weather causes the outside of the roof to be covered with snow, causing the roof to sag and deform, which in turn affects the structural stability of the multi-protection shed and makes it unable to play its due protective role. Summary of the invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: As Figure 1 - Figure 2 shown, this embodiment discloses a multi-prevention shed for the planting and growth of big cherry trees, including a support component 1. The support component 1 can provide stable support for the multi-prevention shed. An adjustment component 2 for controlling the gas humidity introduced into the multi-prevention shed is arranged inside the support component 1. A carrier component 3 is fixedly connected to the support component 1. The carrier component 3 can block the harsh weather outside for the big cherry trees. Two cleaning components 4 are arranged inside the carrier component 3, and the cleaning components 4 timely scrape off the condensed dew adhering to the inner side of the ceiling 305.

[0022] Furthermore, as Figure 3 - Figure 4As shown in the figure, the support component 1 includes a bottom plate 101, which is made of concrete and can prevent uneven settlement of the multi-protection shed. A water retaining wall 102 for preventing rainwater backflow is provided on the bottom plate 101. An activity door 103 for facilitating the passage of staff is connected to the water retaining wall 102. A plurality of upright columns 104 are evenly provided at the top of the water retaining wall 102. A side shed 105 is connected between adjacent upright columns 104. The side shed 105 plays an isolation role and reduces environmental interference from external factors. A louver fan 110 for promoting air circulation is provided on one side of the side shed 105 away from the activity door 103. One end of the upright column 104 away from the water retaining wall 102 is fixedly connected to a main beam 106. The construction of the upright column 104 and the main beam 106 builds a stable structural framework for the multi-protection shed.

[0023] Further, as Figure 5 - Figure 6 shown, the carrier component 3 includes a top beam 301. A plurality of U-shaped frames 302 are connected to the top beam 301. One end of the plurality of U-shaped frames 302 away from the top beam 301 is fixedly connected to the main beam 106. A plurality of inclined beams 303 are connected to both ends of the top beam 301. One end of the inclined beam 303 away from the top beam 301 is fixedly connected to the main beam 106. A plurality of secondary beams 304 are evenly provided between the inclined beams 303. One end of the plurality of secondary beams 304 is fixedly connected to the top beam 301, and the other end is fixedly connected to the main beam 106. Ceilings 305 for resisting external natural hazards are connected to both sides of the secondary beam 304. The construction of the top beam 301, the inclined beam 303 and the secondary beam 304 ensures the structural stability of the ceiling 305.

[0024] A multi-protection shed often uses a blower 210 to introduce external air into the multi-protection shed for continuous ventilation and air exchange. However, the humidity of the external air is complex and will interfere with the humidity balance inside the multi-protection shed. Further, the adjustment component 2 includes a box body 201, which can wrap and protect the internal components. A plurality of cross beams 108 are evenly provided at the bottom of the box body 201. Both ends of the cross beam 108 are fixedly connected to longitudinal beams 109. Both ends of the longitudinal beam 109 are fixedly connected to the upright column 104. The cross beam 108 and the longitudinal beam 109 jointly provide a working platform for the box body 201 and the water supply device 207. As Figure 7 - Figure 8As shown, a working chamber 202 and a humidifying chamber 203 are provided inside the box body 201. The setting of the working chamber 202 facilitates the humidity adjustment of the outside air. A heating pipe 213 is provided inside the humidifying chamber 203. Water supply pipes 206 are communicated with the side walls on both sides of the humidifying chamber 203. One end of the water supply pipe 206 far from the humidifying chamber 203 is connected to a water supply device 207. The water supply device 207 is connected to the cross beam 108. The water supply device 207 provides 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. A plurality of communication holes 205 are evenly opened on the fixing plate 204. The water vapor generated in the humidifying chamber 203 passes through the communication holes 205, and the water vapor is mixed with the outside air, thereby increasing the air humidity. A ventilation chamber 209 is communicated with the side wall of the working chamber 202 close to the louver 110. A refrigeration pipe 214 for condensing humid air is provided on one side of the working chamber 202 close to the ventilation chamber 209. An exhaust fan 210 is provided inside the ventilation chamber 209. Starting the exhaust fan 210 can introduce fresh air from the outside. A humidity sensor is provided on the exhaust fan 210 to detect the humidity of the outside fresh air. One end of the ventilation chamber 209 far from the exhaust fan 210 is fixedly connected to the louver 110. A plurality of docking holes 212 are opened on the side wall of the working chamber 202 far from the ventilation chamber 209. After processing the humidity of the introduced air, the air enters the inside of the multi-protection shed through the docking holes 212 to realize air circulation. When in use, the refrigeration pipe 214 is started to liquefy the water vapor in the humid air into water droplets, reducing the air humidity; the heating pipe 213 is started to heat the water in the humidifying chamber 203 to generate water vapor, thereby increasing the air humidity, so that the air humidity in the multi-protection shed is always maintained within a preset humidity range.

[0025] In winter, condensation is likely to occur on the inner side of the ceiling 305 of the multi-protection shed, reducing the light transmittance of sunlight. Further, Figure 9 - Figure 11 、 Figure 14As shown, the cleaning component 4 includes a scraper 401, the top of the scraper 401 is in conflict with the bottom of the ceiling 305, and the scraper 401 can scrape the condensation on the ceiling 305 during the back and forth movement. The scraper 401 is connected to the two sides with a water collecting trough 402 for collecting condensation, and the side wall of the main beam 106 is fixedly connected with a drainage trough 107, the top of the drainage trough 107 is in conflict with the bottom of the water collecting trough 402, and the condensation in the water collecting trough 402 enters the drainage trough 107 under the action of gravity, and the end of the water supply equipment 207 away from the water supply pipe 206 is connected to the return pipe 208, and the end of the return pipe 208 away from the water supply equipment 207 is interconnected with the drainage trough 107, and the condensation gathered in the drainage trough 107 flows along the return pipe 208 and enters the water supply equipment 207, thereby realizing the resource cycle of condensation recovery and reuse. Two limiting plates 404 are fixedly connected to the two ends of the side wall of the scraper 401, and 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, and one end of the roller 405 passes through the limiting plates 404 and is connected to a rotating motor 406. A track 407 is provided on one side of the roller 405, and both ends of the track 407 are fixedly connected to the inclined beam 303. The roller 405 and the track 407 are in conflict with each other. A groove is provided on the scraper 401, and the groove matches the track 407. When in use, the roller 405 rotates along the track 407, thereby driving the scraper 401 to scrape off the condensation, thereby solving the problem that the condensation on the inside of the ceiling 305 reduces the photosynthesis of the cherry tree.

[0026] The working principle of the present invention is as follows: the multi-protection shed is connected to a central control module, which controls the exhaust fan 210 to start, and the exhaust fan 210 rotates to drive the fresh air from the outside to circulate quickly. The outside air passes through the louver fan 110 and the ventilation chamber 209 in turn. At this time, the humidity sensor detects the humidity of the outside air and transmits the humidity value to the central control module, which 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 the air humidity to increase significantly, the refrigeration pipe 214 is started, and when the humid air passes through the refrigeration pipe 214, the water vapor in the humid air can quickly condense into water droplets, which adhere to the surface of the refrigeration pipe 214, and then the water droplets flow into the inside of the humidification chamber 203. The air that has undergone condensation and dehumidification 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 less than the preset humidity value, for example, when the evaporation rate of surface water decreases sharply in winter, causing the air humidity to drop significantly, the heating tube 213 is started, and the heating tube 213 heats the water in the humidification chamber 203 to generate water vapor, which enters the working chamber 202 through the connecting hole 205 and mixes with the air, and the air that has undergone evaporation and humidification enters the multi-protection shed through the docking hole 212, thereby effectively ensuring that the air humidity in the multi-protection shed is always maintained within the preset humidity range, creating a more suitable growth environment for the cherry trees in the multi-protection shed.

[0027] It should be noted that when the refrigeration pipe 214 is used to reduce the air humidity, the air temperature is also reduced simultaneously, which is beneficial for the multi-protection shed to maintain the temperature balance in the summer; when the heating pipe 213 is used to increase the air humidity, the air temperature is also increased simultaneously, which is beneficial for the multi-protection shed to maintain the temperature balance in the winter, effectively alleviating the adverse effects of the external temperature on the cherry trees.

[0028] When the staff observes that there is a lot of condensation attached to the inner side of the ceiling 305, the central control module controls the rotating motor 406 to rotate at a set rate. The rotating motor 406 rotates to drive the roller 405 to rotate along the track 407, thereby driving the limit plate 404 to move along the track 407. Since the top of the scraper 401 and the bottom of the ceiling 305 conflict with each other, the scraper 401 can effectively scrape the condensation in the ceiling 305 during the back and forth movement, solving the problem that condensation reduces the photosynthesis of the cherry tree. The scraped condensation follows the guidance of the scraper 401 and slowly flows into the water collection tanks 402 on both sides. Then the condensation in the water collection tank 402 enters the drainage tank 107 under the action of gravity. Then a large amount of condensation begins to gather in the drainage tank 107, flows along the return pipe 208, and finally enters the water supply equipment 207, realizing the resource cycle of condensation recycling and reuse.

[0029] Embodiment 2: The ceiling 305 of the multi-protection shed is usually made of plastic film, which has poor rigidity and is prone to denting and deformation when squeezed by the outside world. After snowing, a large amount of snow accumulates on the ceiling 305, causing the ceiling 305 to dent and deform. At the same time, due to the high temperature inside the multi-protection shed, the snow in contact with the ceiling 305 absorbs heat and melts into water, and then freezes into ice at low temperatures (this process is similar to the process of ice cone formation on the eaves). The strong adhesion of ice will produce greater pressure on the ceiling 305, further strengthening the denting and deformation of the ceiling 305. At this time, the ceiling 305 is low in the middle and high in the surrounding areas, which affects the structural stability of the multi-protection shed and may even cause structural damage, making it unable to play its due protective role. Embodiment 2 is proposed to solve the above problems.

[0030] like Figure 7 - Figure 8 As shown, the top of the working chamber 202 is connected to two hoses 211, and one end of the hose 211 away from the working chamber 202 is connected to the inner bottom of the scraper 401. The scraper 401 is a hollow cavity structure. A ventilation solenoid valve is provided inside the hose 211. The ventilation solenoid valve is controlled to open, and the air in the working chamber 202 can enter the scraper 401 through the hose 211. The movement of the cleaning component 4 will drive the hose 211 to move on the path of multiple U-shaped frames 302 to prevent the hose 211 from colliding with the cherry tree.

[0031] Furthermore, ifFigure 9 - Figure 14 As shown, a pressure sensor is provided on the scraper 401. The pressure sensor is used to detect the magnitude of the pressure received at the top of the scraper 401. A plurality of jet components 403 are evenly provided on the side wall of the scraper 401, and the jet components 403 can eject the air in the working chamber 202. The jet component 403 includes an air storage chamber 4031, and the air storage chamber 4031 is used for transferring and circulating the air in the working chamber 202. The side wall of the air storage chamber 4031 is communicated with the side wall of the scraper 401. An active chamber 4032 is communicated with the air storage chamber 4031. A nozzle 4033 is hermetically slidably connected in the active chamber 4032. The nozzle 4033 can hermetically slide in the active chamber 4032. The top of the nozzle 4033 is close to the ceiling 305. A plurality of ventilation holes 4034 are provided on the side wall of the nozzle 4033. A return spring 4035 is fixedly connected to the bottom of the nozzle 4033. The end of the return spring 4035 away from the nozzle 4033 is fixedly connected to the inner bottom of the air storage chamber 4031. After the return spring 4035 is compressed, the nozzle 4033 moves in the direction close to the air storage chamber 4031, and the side wall of the active chamber 4032 no longer blocks the ventilation holes 4034. At this time, the air in the air storage chamber 4031 enters the nozzle 4033 through the ventilation holes 4034. The air ejected from adjacent nozzles 4033 is connected to each other, thereby forming a complete jet area, effectively improving the snow cleaning effect on the ceiling 305.

[0032] In the case of heavy snow weather, the humidity of the outside air is less 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 humidifying chamber 203 to generate water vapor. The water vapor is mixed with the outside air to form humid hot air, and enters the multi-protection shed through the docking hole 212.

[0033] In the initial stage, the snow in contact with the ceiling 305 absorbs heat and melts into water, and then freezes into ice under the action of low temperature. The continuous development of this process causes the depression deformation of the ceiling 305 to gradually increase. The central control module controls the rotation motor 406 to rotate forward at a set rate. The rotation motor 406 drives the scraper 401 to move forward along the track 407. With the synchronous movement of the scraper 401 and the jet component 403, when the nozzle 4033 starts to contact the depressed area of the ceiling 305, the nozzle 4033 compresses the return spring 4035 and moves in the direction close to the air storage chamber 4031. After detecting the depression deformation on the ceiling 305, the signal is transmitted to the central control module. The central control module controls the ventilation regulating valve to open. Under the action of the pressure difference, the hot air in the working chamber 202 quickly circulates along the hose 211 and enters the scraper 401 and the air storage chamber 4031.

[0034] As the nozzle 4033 descends along the surface path of the concave area until it reaches the lowest point of the concave area, the blocking amount of the side wall of the movable cavity 4032 on the ventilation hole 4034 gradually decreases, so that the volume of hot air passing through the ventilation hole 4034 per unit time continuously increases. The hot air is ejected from the nozzle 4033 to efficiently heat the snow accumulation. At the same time, part of the hot air overflows from the tiny gap between the nozzle 4033 and the ceiling 305 and is connected to the hot air overflowing from the adjacent nozzle 4033 to form a complete jet heating area, further enhancing the heating effect on the snow accumulation. Similarly, when the nozzle 4033 rises from the lowest point of the surface path of the concave area to the flat area of the ceiling 305, the blocking amount of the side wall of the movable cavity 4032 on the ventilation hole 4034 gradually increases, so that the volume of hot air passing through the ventilation hole 4034 per unit time continuously decreases. The reduction of the hot air volume can avoid large fluctuations in the humidity of the air in the shed and can also reduce energy consumption. Subsequently, the central control module controls the rotation motor 406 to reverse at a set rate, and the rotation motor 406 drives the scraper 401 to move backward along the track 407 to complete a snow melting cycle process. Then, the above snow melting cycle process is continuously repeated. The wind force of the hot air received by the snow accumulation changes continuously, realizing pulsed hot air snow melting for the snow accumulation in the concave area on the ceiling 305.

[0035] It should be noted that the scraper 401 has good flexibility and always keeps in close contact with the ceiling 305. Based on this characteristic, when the scraper 401 moves to the concave area, the scraper 401 deforms accordingly following the curve of the concave area. At the same time, relying on its continuous moving power, it can slightly lift up the snow accumulation, ice cubes and liquid water accumulated on the moving path of the scraper 401. Once the scraper 401 leaves the concave area, the originally lifted snow accumulation, ice cubes and liquid water will lose support and re-extrude the ceiling 305 under the action of gravity. The scraper 401 performs a reciprocating cycle movement in the concave area, and the snow accumulation, ice cubes and liquid water on the ceiling 305 will synchronously vibrate up and down, so that the adhesion of the snow accumulation, ice cubes and liquid water to the ceiling 305 will gradually decrease, further enhancing the cleaning effect on the snow accumulation on the ceiling 305.

[0036] In the initial stage of the snow melting operation, when the rotating motor 406 rotates forward, the nozzle 4033 will contact the ceiling 305 before the scraper 401. Since the snow melting ability of the pulsed hot air in the initial stage is lower than the icing ability of the snow accumulation, when the nozzle 4033 passes through the lowest point of the concave area, the compression amount of the return spring 4035 continuously increases. According to the change in the compression amount of the return spring 4035, the concave situation on the ceiling 305 is detected, so as to control the rotation speed of the rotating motor 406 to increase, making the snow and ice on the ceiling 305 vibrate more violently and enhancing the snow melting ability during the forward rotation in the initial stage; when the rotating motor 406 rotates reversely, the scraper 401 will contact the ceiling 305 before the nozzle 4033. When the scraper 401 passes through the lowest point of the concave area, the pressure on the scraper 401 continuously increases. According to the magnitude of the pressure on the scraper 401, the concave situation on the ceiling 305 is detected, so as to control the power of the heating pipe 213 to increase, and the hot air passing through the nozzle 4033 per unit time increases, enhancing the snow melting ability during the reverse rotation in the initial stage. Therefore, in each snow melting cycle in the initial stage, the compression amount of the return spring 4035 and the pressure on the scraper 401 both continuously increase, and the rotation speed of the rotating motor 406 and the power of the heating pipe 213 are correspondingly adjusted to increase, which can further enhance the snow melting ability in the initial stage.

[0037] When the snow continuously absorbs heat and the snow melting ability of the pulsed hot air gradually increases until the snow melting ability of the pulsed hot air is equal to the icing ability of the snow accumulation, when the nozzle 4033 passes through the lowest point of the concave area, the compression amount of the return spring 4035 no longer changes, and when the scraper 401 passes through the lowest point of the concave area, the magnitude of the pressure on the scraper 401 no longer changes, entering the stable snow melting stage.

[0038] In the stable stage, the concave deformation of the ceiling 305 remains unchanged during this process. In each snow melting cycle, the change trend of the blockage amount of the vent hole 4034 remains the same, and the rotation speed of the rotating motor 406 and the power of the heating pipe 213 remain unchanged. After the snow on the ceiling 305 continuously receives the heat transferred by the pulsed hot air and continuously absorbs heat energy until the snow melting ability of the pulsed hot air is greater than the icing ability of the snow accumulation, it enters the snow melting rebound stage.

[0039] During the springback stage, in each snowmelt cycle, the ice on the ceiling 305 continuously absorbs heat under the continuous heat transfer effect and melts into liquid water. Under the combined action of gravity and the scraper 401, the liquid water flows down along the surface of the ceiling 305 and finally detaches from the ceiling 305 and is discharged outside the multi-protection shed. When the rotation motor 406 rotates forward, the compression amount of the return spring 4035 continuously decreases, thereby controlling the rotation speed of the rotation motor 406 to decrease, weakening the vibration of the snow and ice on the ceiling 305. The small vibration can accurately gather a small amount of snow, preventing the snow from splashing and dispersing due to excessive vibration, and making the snowmelt work more thorough. When the rotation motor 406 rotates in reverse, the pressure on the scraper 401 continuously decreases, thereby controlling the power of the heating pipe 213 to decrease, reducing the 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. When the compression amount of the return spring 4035 continuously decreases until it completely returns to the initial state, the compression amount of all the return springs 4035 is zero, and the pressure on the scraper 401 also returns to the initial value. The central control module controls the ventilation regulating valve to close, and the rotation motor 406 stops rotating, completing the melting and cleaning of the snow and ensuring the safety and stability of the multi-protection shed.

[0040] In addition, after the hot air is sprayed on the ceiling 305, it will quickly liquefy into water droplets. The scraper 401 scrapes the water droplets, and the water collecting tank 402 realizes the secondary recycling of the water droplets. It should be noted that the snow around the ceiling 305 is less, 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.

[0041] In the above process, the compression amount of the return spring 4035 and the pressure on the scraper 401 are used to detect the depression deformation of the ceiling 305 respectively. The nozzle 4033 can adaptively adjust the wind force of the pulsed hot air according to the depression deformation, avoiding large fluctuations in the air humidity in the area with a small depression, strengthening the snowmelt and cleaning effect on the snow in the area with a large depression. At the same time, the scraper 401 drives the snow, ice and liquid water on the ceiling 305 to vibrate up and down, gradually reducing the adhesion of the snow, ice and liquid water to the ceiling 305. In addition, during different stages of the snowmelt operation, the rotation speed of the rotation motor 406 and the power of the heating pipe 213 are adjusted correspondingly to complete the thorough cleaning of the snow at different stages on the ceiling 305, effectively solving the potential hidden danger problem of snow accumulation.

[0042] Embodiment 3: This embodiment discloses a protection method for a multi-protection shed for the planting and growth of big cherry trees, including the following steps:

[0043] Step 1: When the humidity of the external air is greater than the preset humidity value, start the refrigeration pipe 214 to reduce the humidity of the air; when the humidity of the external air is less than the preset humidity value, start the heating pipe 213 to increase the humidity of the air. Step 2: Control the scraper 401 to move back and forth along the track 407 to scrape the condensation in the ceiling 305. The condensation passes through the water collecting tank 402, the drainage tank 107 and the water return pipe 208 in sequence and enters the water supply device 207. Step 3: When the nozzle 4033 starts to contact the concave area of the ceiling 305, the return spring 4035 is compressed, and the signal is transmitted to the central control module, which controls the ventilation regulating valve to open. Step 4: When the nozzle 4033 moves along the surface path of the concave area, adaptively adjust the wind force of the pulsed hot air, and at the same time, the scraper 401 drives the snow, ice and liquid water on the ceiling 305 to vibrate up and down.
