Description

Technical Field

[0001] The present invention relates to the technical field of condensation water devices, and in particular to a device for condensing water, collecting water and reducing water loss in sandy area woody plants. Background Art

[0002] As we all know, sandy areas are dry and rainless, and water is one of the main environmental factors limiting plant growth and development. Currently, the main method for protecting rare plants and ancient trees in sandy areas is to alleviate water stress through regular artificial irrigation. However, this method is prohibitively expensive and unsustainable. Furthermore, large-scale artificial afforestation in sandy areas often results in plantations dying due to water shortages, resulting in low survival rates.

[0003] Chinese patent CN 104141327B discloses a device for collecting moisture from desert sand layers. Its technical solution is as follows: a moisture collection device and a condensing device. The moisture collection device includes a cylinder, a heater, and an exhaust pump. A constant pressure valve is provided on the side of the cylinder, and the inner cavity of the cylinder is connected to the outside air through the constant pressure valve. A collection port is provided at the lower end of the cylinder, and a screen is provided in the inner cavity of the cylinder near the collection port. The heater and exhaust pump are located at the upper end of the cylinder, and the air inlet of the exhaust pump is connected to the inner cavity of the cylinder, and the air outlet of the exhaust pump is connected to the air inlet of the condensing device. The condensing device is provided with a water outlet and an exhaust port. Although the solution disclosed in the above patent can achieve moisture collection, it extracts moisture from the sand, which makes the sand drier, making it unsuitable as a device for tending plants in sandy areas.

[0004] Chinese patent CN 118481200 A discloses a desert condensation water device, the technical solution of which is as follows: it includes a mounting box and a condensation column arranged at the bottom of the mounting box, and a water collection tank is provided at the bottom of the condensation column; the interior of the condensation column is a condensation channel, which connects the water collection tank and the mounting box respectively; the side wall of the mounting box is provided with multiple air inlet holes, and the mounting box is provided with a first fan, which blows air into the condensation channel.

[0005] Although the solution disclosed in the above patent can obtain moisture from the air and the collected condensed water can be used to irrigate the planted plants, it does not dissipate heat from the refrigeration plate quickly and effectively. When the heat dissipation efficiency is not achieved, the high temperature can easily lead to a reduced life of the refrigeration plate or even damage it, resulting in cost waste. Moreover, it is obviously impossible to condense moisture from the air with high efficiency, resulting in poor practicality. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a condensation water collection and loss reduction device for woody plants in sandy areas, which can automatically collect natural rainwater and condensed water in the air in the sandy areas to reduce water loss. At the same time, the condensed air can be recycled and reused to cool the refrigeration plate to dissipate heat, thereby improving the condensation efficiency and service life of the device. An automatic irrigation system is also designed to accurately provide water to the target plants.

[0007] The present invention provides a device for reducing water loss and cultivating woody plants in sandy areas by condensing water. The device comprises a heat dissipation chamber, a condensation chamber, a double-layered air inlet tube inserted into the condensation chamber, an air outlet tube and a balance tube inserted into the heat dissipation chamber, a battery, and a solar panel hingedly connected to the air inlet tube. The condensation chamber and the heat dissipation chamber are separated by a semiconductor cooling plate, with the heating end of the semiconductor cooling plate facing the heat dissipation chamber and the cooling end facing the condensation chamber. An air duct connects the two chambers, and the bottom of the condensation chamber has a conical structure. Miniature fans are installed in both the air inlet and the air outlet.

[0008] Through the above technical solution, the solar panels can generate electricity when exposed to sunlight and store it in the battery. The battery supplies power to the semiconductor refrigeration plate and auxiliary equipment. The fans in the inlet and outlet ducts can ensure air circulation. The heat dissipation chamber and the condensation chamber are connected by air ducts. The cooled air in the condensation chamber enters the heat dissipation chamber through the air duct to cool the refrigeration plate, thereby improving its condensation efficiency and service life, and avoiding damage to the refrigeration plate due to excessive temperature in the heat dissipation chamber.

[0009] The present invention is further configured such that the air inlet duct adopts a double-layer structure with an inner cavity and an outer cavity, the micro fan is arranged in the inner cavity, and the outer cavity is used to collect natural rainwater intercepted by the solar panels; the upper parts of the air inlet duct, air outlet duct, and balance duct are all provided with dust and rainproof covers.

[0010] Through the above technical solution, the condensation channel and the water collection channel can be separated in the air inlet tube, thereby preventing the inflow of rainwater from damaging the fan and preventing dust from entering.

[0011] The present invention is further configured such that a water level sensor and a condensing chamber temperature sensor are installed in the condensing chamber; a first induction solenoid valve is installed at the root of the air inlet tube in the condensing chamber, and a second induction solenoid valve is installed at the place where the condensing chamber is connected to the air duct.

[0012] Through the above technical solution, when the device is working, the first induction solenoid valve is in a normally open state, the second induction solenoid valve is closed, the fan in the air inlet tube supplies air to the condensing chamber, and the refrigeration plate works to cool. When the air temperature in the condensing chamber is lower than a certain value, the second induction solenoid valve opens, and the cooled air is transported to the heat dissipation chamber through the air duct. When the temperature in the condensing chamber rises to a certain value, the second induction solenoid valve closes; when the water level in the condensing chamber reaches a limit value, the system stops running, the first and second induction solenoid valves are closed, and the condensing chamber is in a sealed state to prevent water loss.

[0013] The present invention is further configured such that a heat dissipation cavity temperature sensor is installed in the heat dissipation cavity, two rows of air ducts are installed above the heating end of the semiconductor refrigeration plate, and air outlets are evenly opened on the air ducts facing downward, directly facing the heating end of the semiconductor refrigeration plate.

[0014] Through the above technical solution, when the system is working, the air outlet fan exhausts air outwards, and the balance tube balances the air pressure in the heat dissipation cavity to ensure air circulation in the cavity; the air duct blows the cooled air in the condensation cavity evenly to the heating end of the semiconductor refrigeration plate to reduce its surface temperature; when the temperature in the heat dissipation cavity reaches the highest critical value, the system reduces the power, and when it exceeds the critical value, the system stops running, thereby protecting the semiconductor refrigeration plate and extending its service life.

[0015] Furthermore, the solar panel is hingedly connected and fixed to the upper part of the air inlet tube, and the fixed part is connected to the raindrop sensor; a water baffle is arranged around the panel to guide rainwater to the outer cavity of the air inlet tube.

[0016] Through the above technical solution, when it rains outside, the raindrop sensor receives a rain signal and unlocks the solar panel holder, allowing the solar panel to rotate along the wall of the air inlet tube, so that it can face the wind and obtain the maximum rain-facing area. Under the action of the water baffle, the rainwater is guided to the lowest guide groove and flows into the outer cavity of the air inlet tube. It flows through the outer cavity of the air inlet tube to the condensation chamber for storage. After the rain stops, the solar panel resets.

[0017] Furthermore, heat sinks are installed at both the heating and cooling ends of the semiconductor refrigeration fins. The fins can be single or multiple, connected in parallel. When multiple fins are connected in parallel, the heating surfaces of the fins are all on the same side. They are secured between the heat dissipation chamber and the condensation chamber using thermal insulation material, with cross reinforcement applied to the bottom. The air inlet, outlet, and balance fins are fixed and positioned by the top of the heat dissipation chamber. This technical solution enhances the heat dissipation and cooling efficiency of the fins, facilitating the generation of more condensed water.

[0018] Furthermore, a diversion tube is provided at the bottom of the condensation chamber. The diversion tube is divided into multiple branches that are distributed near the plant roots. A third induction solenoid valve is installed at the end of each diversion tube branch, and a humidity sensor is installed at the rear end. With this technical solution, when there is sufficient water near the plant roots, the third induction solenoid valve closes, and all the water is stored in the condensation chamber. When there is insufficient water near the plant roots, the humidity sensor transmits a signal to open the third induction solenoid valve in the corresponding diversion tube branch, transferring water to the plant roots. When the humidity reaches the required level, the sensor feedback signal causes the solenoid valve to close, allowing water storage to continue.

[0019] In summary, the beneficial effects of the present invention include: being able to effectively collect condensed water in sandy areas, and at the same time being able to collect natural rainwater for storage; generating condensed water through heat exchange of refrigeration plates, and being able to recycle and reuse the condensed air to cool and dissipate heat from the refrigeration plates, thereby improving the condensation efficiency and service life of the device. Furthermore, power regulation can be achieved by connecting multiple groups of refrigeration plates in parallel. In addition, the device of the present invention can automatically distribute the collected water to the roots of the plants without the need for human intervention; it does not require additional power supply, and operates automatically using solar energy. It has a relatively complete system logic and can cope with a variety of complex and extreme situations in sandy areas. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example: Reference Figure 1 The schematic diagram of the overall structure of the sandy woody condensation water collection and loss reduction device is shown. It includes a heat dissipation chamber 1 in the upper half of the cavity, a condensation chamber 2 in the lower half, an air inlet duct 3 inserted into the condensation chamber 2, an air outlet duct 4 inserted into the heat dissipation chamber 1, a balancing tube 5 between the air inlet duct 3 and the air outlet duct 4, a battery 17, and a solar panel 6 hingedly connected to the air inlet duct. The condensation chamber 2 and the heat dissipation chamber 1 are separated by a semiconductor cooling plate 21. The heating end of the semiconductor cooling plate 21 faces the heat dissipation chamber 1, and the cooling end faces the condensation chamber 2. The two chambers are connected by an air duct 18. The bottom of the condensation chamber 2 has a conical structure. Micro fans are installed in both the air inlet duct 3 and the air outlet duct 4.

[0024] The solar panel 6 generates electricity when it receives sunlight and stores it in the battery 17. The battery 17 supplies power to the semiconductor refrigeration plate 21 and auxiliary equipment (fans, sensors, solenoid valves). The air inlet fan 7 and the air outlet fan 8 can ensure air circulation. The heat dissipation chamber 1 and the condensation chamber 2 are connected by an air duct 18. The cooled air in the condensation chamber 2 enters the heat dissipation chamber 1 through the air duct 18 to cool and dissipate heat for the semiconductor refrigeration plate 21, thereby improving its condensation efficiency and service life and avoiding damage to the semiconductor refrigeration plate 21 due to excessive temperature in the heat dissipation chamber 1.

[0025] See further Figure 2 The air inlet 3 adopts a double-layer structure, with an inner cavity and an outer cavity. The air inlet fan 7 is located in the inner cavity, and the outer cavity is used to collect natural rainwater intercepted by the solar panels 6. The upper parts of the air inlet 3, air outlet 4, and balance cylinder 5 are all equipped with dust and rainproof covers 16. In this way, the condensation channel and water collection channel can be separated in the air inlet by the inner and outer cavities, preventing the inflow of rainwater from damaging the air inlet fan 7 and preventing dust from entering.

[0026] The lower half of the sandy area woody condensation water collection and loss reduction cultivation device of the present invention can be buried under the ground. Specifically, the semiconductor refrigeration plate 21 and the part below can be buried underground to reduce heat loss. At the same time, the device is fixed, and the part above the semiconductor refrigeration plate 21 is above the ground.

[0027] See also Figures 1 to 5 , a water level sensor 23 is installed in the condensing chamber 2 ( Figure 5 ) and condensing chamber temperature sensor 24 ( Figure 3 ). See Figure 1 A first induction solenoid valve 12 is installed at the root of the air inlet 3 in the condensing chamber 2, and a second induction solenoid valve 13 is installed at the point where the condensing chamber 2 connects to the air duct 18. When the entire device is in operation, the first induction solenoid valve 12 is normally open, the second induction solenoid valve 13 is closed, the air inlet fan 7 supplies air to the condensing chamber 2, and the semiconductor refrigeration plate 21 works to cool. When the air temperature in the condensing chamber 2 is lower than a certain value, the second induction solenoid valve 13 opens, and the cooled air is transported to the heat dissipation chamber 1 through the air duct 18. When the temperature in the condensing chamber 2 rises back to a certain value, the condensing chamber temperature sensor 24 transmits a signal, and the second induction solenoid valve 13 closes ( Figure 2 ); When the water level in the condensing chamber 2 reaches the limit value, the water level sensor 23 transmits a signal and the system stops running ( Figure 5 ), the first induction solenoid valve 12 and the second induction solenoid valve 13 are closed, and the condensation chamber 2 is in a sealed state to prevent water loss.

[0028] See also Figure 5A heat dissipation chamber temperature sensor 25 is installed in the heat dissipation chamber 1. Two rows of air ducts 18 are installed above the heating end of the semiconductor cooling plate 21. Uniform air vents 20 are provided on the air ducts 18, facing downward and directly toward the heating end of the semiconductor cooling plate 21. When the system is operating, the air outlet fan 8 exhausts air outward, and the balance cylinder 5 balances the air pressure in the heat dissipation chamber 1, ensuring air circulation within the chamber. Multiple air vents 20 evenly blow the cooled air in the condensation chamber 2 toward the heating end of the semiconductor cooling plate 21, lowering its surface temperature. When the temperature in the heat dissipation chamber 1 reaches the highest critical value, the system reduces power. When the critical value is exceeded, the system stops operating, protecting the semiconductor cooling plate 21 and extending its service life.

[0029] See also Figure 1 The solar panel 6 is hingedly fixed to the upper part of the air inlet 3. A raindrop sensor 9 is connected to the fixed point and equipped with a solar panel holder 10. A water baffle 11 is set around the panel to divert rainwater into the outer cavity of the air inlet 3. When it rains outside, the raindrop sensor 9 receives a rain signal and unlocks the solar panel holder 10, allowing the solar panel to rotate along the wall of the air inlet 3, so that it can face the wind and obtain the maximum rain-facing area. Under the action of the water baffle 11, the rainwater is diverted to the lowest guide groove and flows into the outer cavity of the air inlet 3. From the outer cavity of the air inlet 3, it flows into the condensation chamber 2 for storage. After the rain stops, the solar panel 6 returns to its original position.

[0030] See also Figure 5 , a heat sink 22 is installed at both the heating end and the cooling end of the semiconductor refrigeration plate 21; the semiconductor refrigeration plate 21 is a single plate or several plates connected in parallel. When several semiconductor refrigeration plates 21 are connected in parallel, the cooling efficiency can be adjusted by controlling the number of semiconductor refrigeration plates 21 working, and the cost of small-area refrigeration plates is lower. In this embodiment, the semiconductor refrigeration plates 21 are arranged in parallel. When connected in parallel, the heating surfaces of the several semiconductor refrigeration plates 21 are all on the same surface, and are fixed between the heat dissipation chamber 1 and the condensation chamber 2 using insulation material, and a cross reinforcement is used at the bottom of the whole. The air inlet duct 3, air outlet duct 4, and balance duct 5 are fixed and limited by the top of the heat dissipation chamber 1.

[0031] See also Figure 2 A flow conduit 15 is installed at the bottom of the condensation chamber 2. This conduit 15 is divided into multiple branches that are distributed near the plant roots. A third induction solenoid valve 14 is installed at the end of each branch of the conduit 15, and a humidity sensor 19 is installed at the rear end. When there is sufficient water near the plant roots, the third induction solenoid valve 14 closes, and all the water is stored in the condensation chamber 2. When there is insufficient water near the plant roots, the humidity sensor 19 transmits a signal to open the third induction solenoid valve 14 in the corresponding branch of the conduit 15, transferring water to the plant roots. When the humidity reaches the desired level, the humidity sensor 19 sends a feedback signal to close the third induction solenoid valve 14, allowing water to continue to be stored.

[0032] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
