[0039] An embodiment of the present application provides a water intake device based on photovoltaic power generation, including a housing 10 having a heat preservation cavity 11. A raw water tank 20 is arranged in the heat preservation cavity 11, and the raw water tank 20 is connected to a water treatment system; a water using device connected to the water treatment system through a purified water intake pipe 24, and at least a part of the purified water intake pipe 24 is located in the heat preservation cavity 11; a heat storage or heating device 30 arranged in the heat preservation cavity 11, and a heating element 31 is arranged in the heat storage or heating device 30; at least one group of photovoltaic modules arranged on the outer wall of the housing 10, and at least one group of photovoltaic modules is configured to supply power to part or all of the water treatment system and / or the heating element 31.

A faucet is provided at the water outlet end of the water purification pipeline, and the user can draw water through the faucet. A set of photovoltaic modules can be inclinedly arranged on the outer top wall of the housing 10, a set of photovoltaic modules can be arranged on the south-facing side wall of the housing 10, a set of photovoltaic modules can be arranged on the west-facing side wall of the housing 10, a set of photovoltaic modules can be arranged on the east-facing side wall of the housing 10. At least one set of photovoltaic modules is provided on the outer wall of the housing 10, and the above situations can be arranged and combined according to actual usage requirements. Particularly, taking the example that a set of photovoltaic modules are respectively arranged on the top wall, south side wall, and west side wall of the housing 10, all the photovoltaic modules can be used to supply power to the heating element 31 at the same time, or can be used to supply power to the water treatment system at the same time, or a part of them can supply power to the heating element 31, and the other part can supply power to the water treatment system. The water treatment system can be a device for treating water, or it can only play the role of pumping water. A storage element 50 (storage battery) can be arranged in the heat preservation cavity 11. The photovoltaic modules can transmit the generated electric energy to the storage battery for storage, and the storage battery supplies power to the devices that need electric energy. The devices that need electricity can be the water treatment system, or the water intake and replenishment system, such as a water pump for replenishing the water source into the original water tank, or a lighting device, or an additional heating device, or a shower device, etc. The heat storage or heating device can also be an electric heater or other devices. The heat storage or heating device can also directly heat the air in the heat preservation cavity 11.

[0041] An embodiment of the present application provides a water purification and water intake device based on photovoltaic power generation, including a housing 10 and a water purification and water intake pipe 24. The housing 10 has a heat preservation cavity 11, an original water tank 20 is arranged in the heat preservation cavity 11, and the original water tank 20 is connected to a water treatment system; the water purification and water intake pipe 24 is connected to the water treatment system, and at least a part of the water purification and water intake pipe 24 is located in the heat preservation cavity 11; wherein, a first photovoltaic module 41 is arranged on the outer top wall of the housing 10, the first photovoltaic module 41 is inclinedly arranged, a second photovoltaic module 42 is arranged on the outer side wall of the housing 10, and the second photovoltaic module 42 is vertically arranged; a heat storage or heating device 30 is arranged in the heat preservation cavity 11, a heat preservation solution is contained in the heat storage or heating device 30, at least two groups of heating elements 31 are arranged in the heat storage or heating device 30, a storage element 50 for supplying power to the water treatment system is arranged in the heat preservation cavity 11, the second photovoltaic module 42 is used to supply power to one of the heating elements 31 and / or the storage element 50, and the first photovoltaic module 41 is used to supply power to the remaining heating elements 31 and / or the storage element 50.

[0042] In this embodiment, the heat preservation cavity 11 is a relatively airtight space. The original water tank 20 is used to hold groundwater. The original water tank 20 is connected to an underground water pipe, and the lower end of the underground water pipe is immersed in the groundwater. For example, the underground water pipe can be immersed in the groundwater of a well. The underground water pipe is provided with an underground water pump, and the groundwater is pumped into the original water tank 20 through the underground water pump for storage. A water treatment system is also arranged in the heat preservation cavity 11. The water treatment system is used to purify the water in the original water tank 20. The groundwater is purified into directly drinkable water meeting certain standards through the water treatment system, and then discharged through the purified water intake pipe 24. A valve is arranged at the water outlet end of the purified water intake pipe 24. It can be expected that the original water tank 20 can also be part of the water treatment system, that is, the pretreatment system 21 can directly treat groundwater or tap water without first storing the groundwater or tap water in the original water tank 20 for storage. The purified water intake pipe 24 can be directly accessible. Users with any permission can directly draw water through the purified water intake pipe 24, or the water intake permission can be set according to actual usage needs, or certain preset conditions need to be met to draw water. For example, a certain currency score needs to be scanned and paid, or it is necessary to become a monthly / quarterly / annual member, etc. Structures such as a power cabinet, an inverter, and a control cabinet are also arranged in the heat preservation cavity 11.

[0043] It should be noted that the material of the heat storage or heating device 30 can be made of a heat-conducting material, such as iron, etc. The meaning that at least part of the purified water intake pipe 24 is located in the heat preservation cavity 11 is that the heat generated by the heat storage or heating device 30 can be transferred to the purified water intake pipe 24, reducing the situation that the purified water intake pipe 24 cannot normally discharge water due to freezing in the low-temperature outdoor environment. When part of the purified water intake pipe 24 is located in the heat preservation cavity 11, the water outlet of the purified water intake pipe 24 is located outside the heat preservation cavity 11, and users draw water outside the heat preservation cavity 11 when drawing water; when the purified water intake pipe 24 is entirely located in the heat preservation cavity 11, that is, the water outlet of the purified water intake pipe 24 is located inside the heat preservation cavity 11, users need to enter the heat preservation cavity 11 to draw water when drawing water, enabling users to be in a warm environment when drawing water and improving the user's water intake experience.

[0044] A first photovoltaic module 41 is provided on the outer top wall of the housing 10. The first photovoltaic module 41 is inclined, which means that there is a certain angle, such as 30°-60°, between the surface of the photovoltaic panel of the first photovoltaic module 41 and the horizontal plane. The second photovoltaic panel is vertically provided on the outer wall of the housing 10, which means that the included angle between the surface of the photovoltaic panel of the second photovoltaic module 42 and the horizontal plane is 90°. Due to the influence of the illumination time and illumination angle on photovoltaic power generation, generally speaking, the power generation efficiency of the first photovoltaic module 41 is higher than that of the second photovoltaic module 42. At least two sets of heating elements 31 are provided in the heat storage or heating device 30. The heating elements 31 can be heating wires. According to different seasonal environmental conditions, the temperature maintained in the heat storage or heating device 30 may be different. Since the power generation efficiency of photovoltaic power generation is different at different time periods. The electric energy generated by the second photovoltaic module 42 is preferentially supplied to one of the heating elements. When the electric energy generated by the second photovoltaic module 42 is exactly enough for the power consumption demand of the heating element, the electric energy generated by the first photovoltaic module 41 is used to store energy in the energy storage element 50. The energy storage element 50 can be a storage battery. When the second photovoltaic module 42 meets the power consumption demand of the heating element and there is surplus electric energy, the surplus electric energy of the second photovoltaic module 42 and the electric energy generated by the first photovoltaic module 41 are used to store energy in the energy storage element 50. When the second photovoltaic module 42 does not meet the power consumption demand of the heating element, all the electric energy generated by the second photovoltaic module 42 is used to supply power to one of the heating elements, and the first photovoltaic module 41 supplies power to the remaining heating elements. If the second photovoltaic module 42 has surplus electric energy, it is transported to the energy storage element 50 for storage. By providing at least two sets of heating elements, different usage requirements can be adapted under different temperature environmental conditions.

[0045] For ease of understanding, taking the example of arranging the first photovoltaic module 41 on the outer top wall of the housing 10 and arranging the second photovoltaic module 42 on the outer wall of the housing 10 facing south, a quantitative example is given. Suppose it is necessary to maintain the temperature in the heat preservation chamber 11 at 5°C. At this time, the outer wall temperature of the heat storage or heating device 30 needs to be 10°C. One heating element 31 can make the outer wall temperature of the heat storage or heating device 30 reach 10°C. The heating element 31 heats the heat preservation solution in the heat storage or heating device 30, and the electric energy required to make the outer wall of the heat storage or heating device 30 reach 10°C is 10 units. If the power generation of the second photovoltaic module 42 is 10 units, then all the electric energy generated by the second photovoltaic module 42 is provided to the heating element 31. At this time, all the electric energy generated by the first photovoltaic module 41 is provided to the energy storage element 50; if the power generation of the second photovoltaic module 42 is 15 units, then 10 units of the electric energy generated by the second photovoltaic module 42 is provided to the heating element 31, and the remaining 5 units of electric energy are supplied to the energy storage element 50. At this time, all the electric energy generated by the first photovoltaic module 41 is provided to the energy storage element 50; if the power generation of the second photovoltaic module 42 is 5 units, then all the electric energy generated by the second photovoltaic module 42 is provided to the heating element 31, and the first photovoltaic module 41 provides 5 units of electric energy to the heating element 31. It should be noted that the above values are only for intuitive representation and are not actual usage limitations.

[0046] The structures of the first photovoltaic module 41, the second photovoltaic module 42, and the third photovoltaic module 43 are the same. The working principle of the photovoltaic module is based on the photovoltaic effect of semiconductor materials. When sunlight shines on the surface of the photovoltaic module, photons are absorbed by the semiconductor material and excite electrons to jump to a higher energy level, forming free electrons and holes. The free electrons and holes move and separate in the semiconductor to form an electric current. In the structure of the photovoltaic module, a P-type semiconductor and an N-type semiconductor form a PN junction. When electrons and holes move to this interface, charge separation will occur and a voltage will be generated. When an external circuit is connected to the photovoltaic module, electrons will flow through the circuit to form an output current.

A heat preservation layer is arranged on the inner wall of the annular frame 13, and the heat preservation layer is located between the inner support 15 and the annular frame 13.

[0049] In this embodiment, Figure 3The skeleton structure is essentially the housing 10. An integral skeleton is formed by the annular frame 13 and the connecting rod 14. A plurality of inner brackets 15 arranged and distributed along the first direction are provided on the connecting rod 14. The inner brackets 15 are arranged on one side of the annular frame 13. There is a first gap between the inner brackets 15 and the annular frame 13 in the first direction, which increases the contact points with the connecting rod 14 and improves the structural stability. There is a gap between the inner brackets 15 and the annular frame 13 in the second direction, and the second direction is perpendicular to the first direction. The thermal insulation layer is arranged in the gap between the inner brackets 15 and the annular frame 13 in the second direction, which plays a role in limiting the thermal insulation layer, facilitating the installation of the thermal insulation layer. By means of mechanical limitation, it is also convenient to disassemble the thermal insulation layer. The thermal insulation layer can be made of polyurethane, and the thermal insulation layer can be a polyurethane board. Protective layers can be provided on the outer wall of the annular frame 13 and the inner wall of the inner brackets 15, and the protective layers can be iron sheets. In particular, the inner brackets 15 can be annular structures, or the inner brackets 15 can also be set as a part of the annular structure according to actual needs. During the installation process, one side wall of the housing 10 can be installed close to the wall of the external environment. Except for the annular frames 13 at both ends, the annular frames 13 between the two ends are all wrapped by thermal insulation materials.

[0050] It should be noted that the annular frame 13, the connecting rod 14 and the inner brackets 15 of the housing 10 can be welded and installed in the factory, that is, processed into an integral structure in the factory and directly transported to the destination. Only the water supply and drainage pipes need to be installed to complete the installation, reducing the installation difficulty for users. Similarly, the annular frame 13, the connecting rod 14 and the inner brackets 15 of the housing 10 can also be made into modular structures and installed after being transported to the destination. Through the modular structure, it is convenient for transportation and is also beneficial to assemble into frames of different sizes of spaces according to the usage needs of users. At this time, one installation structure of the annular frame 13, the connecting rod 14 and the inner brackets 15 can be to process through holes for the connecting rod 14 to pass through on the annular frame 13 and the inner brackets 15, and external threads are provided on the outer wall of the connecting rod 14. By setting fixing nuts that are threadedly matched with the connecting rod 14 on both sides of the annular frame 13 or the inner brackets 15, the installation of the annular frame 13 or the inner brackets 15 is completed.

[0053] In this embodiment, the pretreatment system 21 mainly includes a variety of filters.
