Description

Technical Field

[0001] The invention relates to the field of cold protection devices, in particular to a cold protection device for garden flowers. Background Art

[0002] Flowers are an important part of garden landscapes and play a vital role in the ornamental value of garden landscapes. However, most flowers only bloom in spring and summer and wither in autumn and winter. Even some flowers with poor cold resistance are at risk of being frozen to death when the temperature is low.

[0003] In order to solve the above problems, people involved in gardening and landscape will take cold-proof measures for flowers with poor cold resistance when the weather is cold, such as wrapping the branches of the flowers or building a protective cover similar to a greenhouse to isolate the flowers from the cold environment outside. For example, a flower cold protection device with publication number CN205611407U is disclosed in the prior art.

[0004] However, this method can only protect the above-ground part of the flowers, but cannot protect the rhizomes below the ground. The rhizomes of the flowers absorb water below the ground, which will cause the branches and leaves of the flowers to have too high a water content. Once the branches and leaves are frozen, the flowers will die. Therefore, the protection device in the prior art needs to have a certain degree of waterproofness, such as a garden tree cold protection device with publication number CN210537817U in the prior art.

[0005] Regarding waterproofing, the existing technology first uses protective devices to block wind and rain to prevent natural precipitation from giving flowers a chance to come into contact with water. The second method is to avoid watering as much as possible when the weather is cold and appropriately reduce the water content of the flowers. However, this method can only play a preventive role. Even if the flowers and the soil around them cannot come into contact with water, the moisture will penetrate into the flowers after the outer soil is moist. Once the soil is already in a moist state, it is difficult for the protective devices in the existing technology to take remedial measures, and the protection effect needs to be improved. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a garden flower cold protection device, which collects water or moisture in the soil through a moisture-absorbing component and removes excess water.

[0045] To facilitate understanding of the technical means, creative features, objectives, and effects achieved by the present invention, the present invention will be further described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0046] In order to address the shortcomings of existing technologies, such as Figure 1-12 As shown, the present invention provides a garden flower cold protection device, comprising a transparent top cover 1, a transparent insulation film 2 fixedly provided at the bottom end of the transparent top cover 1, a bottom ring 5 fixedly provided at the bottom end of the transparent insulation film 2, and a plurality of moisture absorbing components 3 provided on the bottom ring 5;

[0047] The moisture absorbing component 3 includes a fixing pile 301, the bottom end of the fixing pile 301 is a pointed tip, and the bottom ring 5 is provided with a plurality of insertion holes 11 corresponding to the moisture absorbing components 3, and the fixing pile 301 passes through the bottom ring 5 through the insertion holes 11;

[0048] Two baffles 303 that serve as limiters are fixed to the outer ends of the fixing piles 301 . The bottom ends of the baffles 303 are in contact with the top end of the bottom ring 5 , thereby limiting the depth of the fixing piles 301 inserted below the ground.

[0049] The transparent top cover 1 is made of acrylic material, and the transparent thermal insulation film 2 is made of polyethylene. During use, the transparent top cover 1 and the transparent thermal insulation film 2 are covered on the outside of the flower plant, and the bottom ring 5 is in direct contact with the ground, thereby isolating the plant from the external environment. At the same time, the transparent top cover 1 and the transparent thermal insulation film 2 are light-transmitting, and can ensure that the flowers can photosynthesize while isolating the external environment. After the bottom ring 5 is in contact with the ground, the fixing pile 301 is passed through the socket 11 and inserted below the ground until the baffle 303 is in contact with the bottom ring 5, thereby fixing the bottom ring 5 on the ground. In order to ensure sealing, the land around the flowers needs to be as flat as possible and in full contact with the bottom ring 5.

[0050] When the soil around the flowers has a high water content, measures need to be taken to reduce its water content, such as Figure 1 、 5 As shown in Figures 6, when the bottom ring 5 is located on the ground, the portion of the fixing pile 301 extending to the bottom of the bottom ring 5 is inserted below the ground. An inner cavity 309 capable of storing water is provided inside the fixing pile 301. The top of the inner cavity 309 is open, and the outer end of the fixing pile 301 is inlaid with multiple breathable meshes 302 that are connected to the inner cavity 309.

[0051] The top of the fixing pile 301 is provided with a closed sleeve 304 through a threaded sleeve, and the front side of the closed sleeve 304 is fixed with an air inlet pipe 306, through which air can be inflated into the inner cavity 309 to increase the internal air pressure;

[0052] When water seeps into the soil, a pipe 305 for drainage is provided inside the inner cavity 309, and one end of the pipe 305 extends to the top of the closed sleeve 304. When no water seeps out of the soil, a guide rod 307 is provided inside the inner cavity 309, and a sponge sleeve 308 capable of absorbing moisture is fixed to the outer end of the guide rod 307. The top end of the guide rod 307 extends to the top of the closed sleeve 304 and is fixed with an end plate with a limiting function.

[0053] After the bottom ring 5 is fixed to the ground using the moisture absorbing component 3, the moisture absorbing component 3 will be distributed in the soil around the flowers, and the moisture in the soil can pass through the breathable mesh 302 and affect the interior of the inner cavity 309;

[0054] Example 1

[0055] After rain, the water content of the soil is high. If the soil seeps water, the seeped water will enter the inner cavity 309 through the breathable mesh 302 and be stored inside the inner cavity 309. At this time, the sealing sleeve 304 is covered inside the inner cavity 309 to seal the inner cavity 309, and then the cannula 305 is inserted below the water surface inside the inner cavity 309. Air is input into the inner cavity 309 through the air inlet pipe 306. When the air pressure inside the inner cavity 309 increases, the water accumulated inside it will be discharged outward through the cannula 305. During the rainy season, rainfall is frequent, and the water soaked in the soil will continuously seep into the inner cavity 309. Therefore, during the rainy season, the water accumulated in the inner cavity 309 is continuously discharged, and then the soil absorbs rainwater while the water is continuously drained until the rain stops, thereby preventing water from accumulating on the ground and affecting the flowers.

[0056] Example 2

[0057] If the soil is impermeable but still very moist, insert the guide rod 307 into the inner cavity 309 and fix the sponge cover 308 at the outer end of the inner cavity 309. The dry sponge cover 308 has the property of absorbing moisture. The moisture in the soil passes through the breathable mesh 302 and enters the inner cavity 309, where it will be absorbed by the sponge cover 308.

[0058] In general, the moisture absorbing component 3 is buried in the soil around the flowers, and moisture can directly penetrate into the inner cavity 309 through the breathable net 302, and moisture in the soil can also enter the inner cavity 309. After entering the inner cavity 309, the moisture or water can be discharged or absorbed, thereby separating the moisture in the soil and reducing the water content of the soil.

[0059] Even if the soil moisture content is already too high, remedial measures can be taken through the above method to reduce the moisture content of the soil around the flowers as much as possible, thereby preventing the flowers from absorbing too much water and easily freezing, thereby improving the cold protection effect of the flowers.

[0060] In addition to isolating the flowers from the outside air, you also need to take measures to heat and keep them warm, such as Figure 1 、 2 As shown in , 10 and 12, the transparent top cover 1 is provided with a first upright pole 4 and a second upright pole 12 fixed to the ground on both sides, the outer end of the first upright pole 4 is provided with a mounting plate 6 by bolts, and a light sensor 601, a temperature sensor 602, a timer switch 603 and a controller 604 are fixed on one side of the mounting plate 6;

[0061] The light sensor 601, temperature sensor 602, and timer switch 603 are all provided at the input end of the controller 604;

[0062] A battery 23 is fixedly provided at the top of the first vertical pole 4, and a solar panel 7 is provided at the top of the battery 23. The solar panel 7 is used to obtain electrical energy and store the electrical energy in the battery 23 for use by other electrical components. The solar panel 7 is provided at the input end of the controller 604, and the battery 23 is provided at the connection end of the controller 604.

[0063] On sunny days, the air is heated by the heat of sunlight, while on cloudy days, the air is heated by electricity. The heated air is input into the transparent top cover 1 and the transparent insulation film 2 to heat the flower plants. The solar panel 7 can use sunlight to obtain electricity and store the electricity in the battery 23 to power the electrical components. Whether it is sunny or cloudy is determined by the light intensity, and whether the air around the flowers needs to be heated is determined by the temperature. The heating duration and interval are controlled by the timer switch 603.

[0064] When the temperature sensor 602 senses a temperature below 10°C, the controller 604 starts heating the air around the flowers. The timer 603 sets the heating time to 30 minutes, each time lasting 5 minutes. The light sensor 601 senses the light intensity during this process. When the light intensity is below 50,000 Lux, the controller 604 controls the heating to be done by electricity. When the light intensity is above 50,000 Lux, the air is heated by sunlight.

[0065] When it is necessary to drive air flow to heat the environment where the flowers are located, such as Figure 1 、 3 As shown in , 4, 9, and 12, a wind tube 13 is fixedly provided at the outer end of the second upright 12, and a plurality of heating rods 25 for heating the air entering the wind tube 13 are fixedly provided on the inner wall of the wind tube 13, thereby heating the air;

[0066] A detachable bottom plate 26 is provided at the bottom end of the air duct 13 , and a fan 27 is fixed on the bottom plate 26 . The heating rod 25 and the fan 27 are both provided at the output end of the light sensor 601 , and the fan 27 is used to drive the air flow.

[0067] An extension tube 15 is fixedly provided at the outer end of the second upright 12, and an air guide tube 24 is fixedly provided at the bottom end of the extension tube 15 and is fixedly connected to the top end of the air duct 13, so as to guide the air inside the air duct 13 into the extension tube 15;

[0068] When the temperature sensor 602 senses that the temperature is lower than 10°C, the air around the flowers needs to be heated. When the heating time set by the timing switch 603 is reached, the fan 27 starts to work, driving the external air into the wind tube 13, and then enters the extension tube 15 through the air duct 24, and finally enters the transparent top cover 1 and the transparent insulation film 2. During this process, if the light intensity is at the bottom standard, the controller 604 controls the heating rod 25 to be energized, thereby generating heat, heating the air entering the wind tube 13, and allowing it to carry heat into the transparent top cover 1 and the transparent insulation film 2 to heat the air around the flowers.

[0069] On sunny days, the light intensity is high and sunlight can be used to heat the air, e.g. Figure 1 、 3 As shown in Figure 4, a crossbeam 9 is fixed on the outer shell of the battery 23, and a cavity 19 is opened inside the crossbeam 9. A spiral channel 16 connected to the extension tube 15 is fixed at one end of the crossbeam 9, and one end of the spiral channel 16 is communicated with the cavity 19. The spiral channel 16 can prolong the air circulation time.

[0070] The spiral channel 16 is provided with reinforcing plates 17 on both the front and rear sides to enhance the connection strength between the extension tube 15 and the crossbeam 9. The two ends of the reinforcing plates 17 are fixedly connected to the extension tube 15 and the outer ends of the crossbeam 9 respectively.

[0071] A convex lens 10 that plays a focusing role is provided at the top of the spiral channel 16. The convex lens 10 focuses sunlight and heats the spiral channel 16, so that the air absorbs heat and heats up when passing through the spiral channel 16. Brackets 14 are provided on both sides of the convex lens 10 through a rotating shaft. The two brackets 14 are respectively fixed on the top of the beam 9 and the extension tube 15. The convex lens 10 can rotate and adjust the angle according to the direction of the sun.

[0072] The air entering the extension tube 15 then enters the cavity 19 through the spiral channel 16. If the light intensity is sufficient, the heating rod 25 no longer heats the air. Instead, the convex lens 10 focuses the sunlight and concentrates it on the spiral channel 16, heating the spiral channel 16. The air obtains heat and heats up when passing through the spiral channel 16, and brings the heat into the transparent top cover 1 and the transparent thermal insulation film 2.

[0073] The key parts of flowers to keep warm are the tips of branches and leaves that are prone to freezing, such as Figure 1 、 2 As shown in Figures 4, 7 and 8, a connecting pipe 20 is fixedly provided at the bottom end of the crossbeam 9. The bottom end of the connecting pipe 20 extends into the interior of the transparent top cover 1 and is fixedly connected to the transparent top cover 1. The top end of the connecting pipe 20 communicates with the cavity 19.

[0074] A diversion component 18 is fixedly provided at the bottom end of the connecting pipe 20. The diversion component 18 includes a hollow disc 1801 fixedly provided at the bottom end of the connecting pipe 20. A plurality of diversion hoses 1802 capable of dispersing the airflow are fixedly provided at the bottom end of the hollow disc 1801. A plurality of first spray holes 1804 are provided at the outer end of the diversion hose 1802. When the diversion hose 1802 is passed through the branches and leaves of the flowers, the first spray holes 1804 can transport the airflow to various parts of the flowers to heat them.

[0075] The heated air enters the cavity 19, and then enters the diversion component 18 inside the transparent top cover 1 and the transparent insulation film 2 through the connecting pipe 20. The various diversion hoses 1802 in the diversion component 18 pass through the branches and leaves of the flower plants and are dispersed in various parts of the flower plants. When the heated air enters the transparent top cover 1 and the transparent insulation film 2, it first enters the hollow disc 1801, and then flows into the various diversion hoses 1802 in a dispersed manner, and is blown to various parts of the flower plants through the first nozzle 1804. With this heating method, the hot air can be unobstructed by the external branches and leaves of the flowers, so that all parts of the flower plants can be evenly heated, effectively preventing the branches and leaves of the flowers from catching cold and freezing.

[0076] In addition to blowing towards the flower plants, it can also dry the soil at the bottom of the flowers, such as Figure 1 、 2 As shown in Figures 4, 7 and 8, a hollow ball head 1803 is fixedly provided at the bottom end of the diversion hose 1802, and the hollow ball head 1803 can contact the ground. A plurality of second spray holes 1805 are provided at the outer end of the hollow ball head 1803 to blow the air flow toward the ground, thereby accelerating the evaporation of moisture in the air flow rate on the ground.

[0077] While flowing along the diversion hose 1802, the air can also enter the hollow ball head 1803, and the hollow ball head 1803 is distributed on the ground around the flower plants. The hot air blown out through the second nozzle 1805 can heat the ground and speed up the air flow rate on the ground, thereby evaporating the moisture of the ground soil and preventing the transparent top cover 1 and the transparent insulation film 2 from hindering the evaporation of soil moisture in the process of protecting the flowers.

[0078] During use, dust and snow will affect the light transmittance of the transparent top cover 1 and the transparent insulation film 2. Figure 1 、 4 As shown in Figures 11, a hollow ring 8 is provided on the top of the transparent insulation film 2. The top of the hollow ring 8 is fixedly connected to the crossbeam 9. A plurality of exhaust holes 22 are provided at the bottom of the hollow ring 8. The airflow ejected downward through the exhaust holes 22 cleans the dust and debris on the outer ends of the transparent top cover 1 and the transparent insulation film 2.

[0079] An external pipe 21 for conducting airflow is fixedly provided at the outer end of the hollow ring 8. One end of the external pipe 21 is fixedly connected to the transparent insulation film 2. The airflow entering the transparent top cover 1 and the transparent insulation film 2 is finally discharged through the external pipe 21.

[0080] The air that enters the transparent top cover 1 and the transparent thermal insulation film 2 is eventually discharged outward through the external tube 21. The air passes through the external tube 21 to reach the inside of the hollow ring 8, and then blows downward through the exhaust hole 22 at the bottom end of the hollow ring 8. After being blown downward, the air blows toward the surface of the transparent top cover 1 and the transparent thermal insulation film 2, thereby utilizing the flowing air to clean snow or dust that may be attached to the surface of the transparent top cover 1 and the transparent thermal insulation film 2, to prevent it from affecting the light transmittance of the transparent top cover 1 and the transparent thermal insulation film 2.

[0081] This protective device is suitable for single planted flowers, but not for large-scale planted flowers. During use, the first vertical pole 4 and the second vertical pole 12 are first inserted into the soil on both sides of the flower plant and fixed, and then the transparent top cover 1 and the transparent insulation film 2 are covered on the outer end of the flower plant to isolate the external environment and keep the flower plant warm. Subsequently, the moisture absorption component 3 is fixed to the bottom ring 5 through the socket 11 and the bottom ring 5 is fixed to the ground. The fixing pile 301 is inserted into the soil around the flower, and the moisture in the soil enters the inner cavity 309 and is separated from the soil, thereby reducing the moisture content of the soil and preventing the flowers from freezing due to high moisture content.

[0082] At the same time, when the temperature is below 10°C, the fan 27 drives the air flow, heats the air and then inputs it into the transparent top cover 1 and the transparent thermal insulation film 2. The heated air temperature is 30-40°C, and the air around the flowers is intermittently heated. After entering the transparent top cover 1 and the transparent thermal insulation film 2, the air first enters the diversion component 18. The diversion component 18 disperses the air and blows it to various parts of the flower plants to heat them evenly. At the same time, the air is blown to the ground to accelerate the evaporation of moisture on the surrounding ground, thereby preventing the transparent top cover 1 and the transparent thermal insulation film 2 from affecting the evaporation of soil moisture and making it difficult to reduce the soil moisture content.

[0083] The basic principles, main features and advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
