Description

Technical Field

[0001] This invention relates to the field of balcony ecological farming technology, and in particular to a water supply system for enclosed balcony ecological farming. Background Technology

[0002] Raising ornamental fish and / or planting landscape plants are common methods for beautifying the environment in homes and many public places. These methods not only beautify the living environment but also allow for the raising of edible, pollution-free fish and / or the cultivation of organic vegetables, ensuring food safety and the health of family members. This type of farming and aquaculture has received increasing attention.

[0003] Urban high-rise buildings or low-rise houses typically have balconies. To ensure privacy and safety, these balconies are usually enclosed. Enclosed balconies offer good lighting and sealing, therefore, the aforementioned farming and aquaculture activities are generally located on balconies.

[0004] Conventional aquaculture typically involves setting up enclosures where plants and fish are placed, with water changed periodically. Alternatively, plants can be grown in pots and watered regularly. The water source for these methods is usually tap water, but conventional tap water generally does not meet the needs of aquaculture. Therefore, a rainwater harvesting device has been developed.

[0005] However, conventional rainwater harvesting devices are generally only used to collect rainwater. But if rainwater is left for a long time, it will breed microorganisms and dirt, which is also unsuitable for planting and aquaculture. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention provides an enclosed balcony ecological aquaculture water supply system, comprising:

[0007] The first water storage mechanism includes a first water storage tank and a first water guide component connecting the first water storage tank and the outside.

[0008] The second water storage mechanism includes a second water storage tank connected to an external water collection device, and a second water guide connecting the first water storage tank and the second water storage tank. The second water storage tank is disposed inside the first water storage tank and can move along the height direction.

[0009] A locking mechanism, connected to the first water guide, is adapted to lock or unlock the first water guide so that the first water guide has a conducting state and a cut-off state; the locking mechanism includes an unlocking member that contacts the second water tank, and the liquid level change in the second water tank causes the weight of the second water tank to change, thereby driving the unlocking member to move so that the first water guide switches between the conducting state and the cut-off state.

[0010] When the liquid level in the second water tank reaches a first set value, it flows to the first water tank through the second water guide. When the liquid level in the first water tank reaches a second set value, it flows to the first water guide. The first water guide is locked by the locking mechanism to be in the cut-off state. When the liquid level in the second water tank reaches a third set value, it presses the unlocking member to move, causing the first water guide to switch to the conduction state. The liquid in the first water tank flows to the outside through the first water guide.

[0011] In one embodiment, the locking mechanism further includes a locking member connected to the first water guide member, and a transmission member connecting the unlocking member and the locking member respectively;

[0012] The unlocking component moves under the gravity of the second water tank to transmit force to the locking component through the transmission component, thereby unlocking the locking component.

[0013] In one embodiment, the locking element is a lever-type pressure reducing valve or a pressure sensor.

[0014] In one embodiment, the first water storage mechanism further includes a floating component disposed inside the first water storage tank and located below the second water storage tank;

[0015] The floating component floats with the change of liquid level in the first water tank, so that when it floats to a set position, the liquid in the first water tank can flow to the outside through the first water guide in the conducting state.

[0016] The set position is the liquid level position that is higher than or equal to the second set value.

[0017] In one embodiment, the floating component includes a buoyancy plate and a gravity plate connected to the buoyancy plate via a connector and located below the buoyancy plate;

[0018] The gravity of the gravity plate is less than the buoyancy of the liquid in the first water tank.

[0019] In one embodiment, the buoyancy plate is provided with a flow hole;

[0020] The outlet end of the second water guide is located above the buoyancy plate, so that the liquid flowing into the first water storage tank flows through the flow hole to the gravity plate.

[0021] In one embodiment, the gravity plate includes a plate body and scraping members connected to both ends of the plate body. When the plate body floats up and down with the buoyancy plate, the scraping members are adapted to scrape and clean the inner wall of the first water storage tank.

[0022] In one embodiment, the plate has a hollow cavity and a hole communicating with the hollow cavity;

[0023] The inlet end of the first water guide is positioned facing the bottom wall of the first water storage tank and is connected to the hollow cavity. The dirt scraped by the scraper flows to the bottom of the plate under the floating action of the plate, and flows into the hollow cavity with the liquid through the holes under the suction action of the first water guide until it flows to the outside.

[0024] In one embodiment, the first water guide and the second water guide are inverted U-shaped hoses, with the end of the inverted U-shaped hose immersed in the liquid located above the other end that is not immersed in the liquid along the height direction.

[0025] In one embodiment, the third setting value is greater than or equal to the first setting value, and the first setting value is greater than or equal to the second setting value.

[0026] The beneficial effects of this invention are reflected in the following: by providing a first water storage mechanism, a second water storage mechanism, and a locking mechanism, the first water storage mechanism includes a first water tank and a first water guide connecting the first water tank to the outside; the second water storage mechanism includes a second water tank disposed within the first water tank and a second water guide connecting the first and second water tanks; the second water tank is connected to an external water collection device; the locking mechanism is connected to the first water guide to switch the first water guide between a conducting state and a cut-off state, and the unlocking part of the locking mechanism contacts the second water tank; the external water collection device supplies liquid to the second water tank; when the liquid level in the second water tank reaches a first preset value, the liquid inside can be released through the first water collection device. The two water guides flow into the first water tank. When the liquid level in the first water tank reaches a second preset value, the liquid can flow into the first water guide, which is in a closed state. When the liquid level in the second water tank reaches a third preset value, the second water tank can press the unlocking mechanism to switch the first water guide to a conducting state, thereby allowing the liquid in the first water tank to flow to the outside. This forms an automatic water exchange process, where the liquid in the external water collection device flows into the second water tank, the liquid in the second water tank flows into the first water tank, and the liquid in the first water tank flows to the outside. This ensures the freshness of the liquid in the first water tank, thus meeting the corresponding planting and breeding needs in a convenient and quick manner. Attached Figure Description

[0038] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Reference Figure 1 , Figure 5 and Figure 7A preferred embodiment of the present invention provides an enclosed balcony ecological aquaculture water supply system 200, which is installed on an enclosed balcony. The enclosed balcony includes a frame composed of profiles 100 and glass installed within the frame, thereby ensuring good waterproofing, sealing, and privacy. In this embodiment, the profiles 100 are made of aluminum, which has advantages such as being lightweight and inexpensive. In other embodiments, the profiles 100 may also be made of steel or other materials; no specific limitation is made here, and the choice depends on the actual situation.

[0041] The water diversion system 200 is used to store rainwater; therefore, the enclosed balcony is equipped with a water collection device 100 connected to the water diversion system 200. The water collection device 100 includes a water collection tank 301 connected to the outside of the profile 100 and a conduit 302 connected to the water collection tank 301. The water collection tank 301 is located above the profile 100, allowing liquid in the water collection tank 301 to be transported to the water diversion system 200 through the conduit 302 via the height difference. The "outer side" of the profile 100 refers to both indoor and outdoor conditions. That is, the side of the profile 100 facing indoors is the inner side, and the side of the profile 100 facing outdoors is the outer side.

[0042] The water collection tank 301 is generally in the shape of a right triangle. The right-angled side of the right triangle is connected to the profile 100, and the hypotenuse of the right triangle is used to guide the flow of rainwater. The conduit 302 is located at the lower end of the water collection tank 301, thereby enabling more rainwater to be diverted into the water diversion system 200.

[0043] Furthermore, the water collection device 100 is not equipped with any sealing components. That is, when it rains outdoors, rainwater can be collected through the collection tank 301 and flow through the conduit 302 into the water supply system 200. When it does not rain outdoors, there is no liquid stored in the collection tank 301, and therefore no liquid is supplied to the water supply system 200. Through this design, no manual intervention is required, reducing operational risks and ensuring the freshness of the liquid flowing into the water supply system 200.

[0044] Please combine Figures 2 to 4 Specifically, the water intake system 200 includes a first water storage mechanism 1 and a second water storage mechanism 2. The first water storage mechanism 1 includes a first water storage tank 11 and a first water guide 12 connecting the first water storage tank 11 to the outside. The second water storage tank 21 includes a second water storage tank 21 and a second water guide 22 connecting the first water storage tank 11 and the second water storage tank 21. When the water collection tank 301 delivers liquid to the water intake system 200 through the conduit 302, the liquid first enters the second water storage tank 21 and then enters the first water storage tank 11 through the second water guide 22. When the water in the first water storage tank 11 is full, it flows to the outside through the first water guide 12.

[0045] Furthermore, in this embodiment, the second water storage tank 21 is disposed within the first water storage tank 11. This arrangement ensures the overall compactness of the water intake system 200. The capacity of the second water storage tank 21 can be set according to actual water storage and replacement needs, and is not specifically limited here.

[0046] In one embodiment, the first water guide 12 can be electrically powered, that is, the first water guide 12 includes a first conduit 302 and a first water pump. When the liquid in the first water tank 11 reaches the target value, the first water pump is started so that the liquid in the first water tank 11 flows to the outside through the first conduit 302. Correspondingly, the second water guide 22 can also be electrically powered, that is, the second water guide 22 includes a second conduit 302 and a second water pump. When the liquid in the second water tank 21 reaches the target value, the second water pump is started so that the liquid in the second water tank 21 flows to the first water tank 11 through the second conduit 302.

[0047] The target value mentioned above can be detected by visual inspection or by installing a water level sensor.

[0048] Furthermore, when the first water guide 12 and the second water guide 22 are electrically powered, corresponding power is required to operate them. Therefore, a power outlet should be provided on the enclosed balcony for the first and second water pumps to connect and obtain power. Alternatively, a generator may be placed on the enclosed balcony to power the first and second water pumps, and also to power other devices that require power (such as the aforementioned water level sensor).

[0049] In another embodiment, the first water guide 12 and the second water guide 22 may also be electrically independent. In this case, the first water guide 12 and the second water guide 22 are inverted U-shaped hoses, with the end of the inverted U-shaped hose immersed in the liquid located above the other end that is not immersed in the liquid, thereby generating a siphon effect. The siphon effect is due to the attraction and potential energy difference between liquid molecules, causing the liquid to flow from the side with higher pressure to the side with lower pressure. In this embodiment, the inverted U-shaped hoses of the first water guide 12 and the second water guide 22 are specifically described.

[0050] Specifically, when it rains outdoors, rainwater flows through the collection tank 301 and the conduit 302 to the second water storage tank 21. When the liquid level in the second water storage tank 21 reaches the first set value, there is no liquid in the first water storage tank 11. Therefore, the pressure in the second water storage tank 21 is greater than the pressure in the first water storage tank 11, causing the liquid in the second water storage tank 21 to flow into the first water storage tank 11 through the second water guide 22. When the liquid level in the first water storage tank 11 reaches the second set value, the pressure in the first water storage tank 11 is greater than the external pressure, and the liquid in the first water storage tank 11 flows to the outside through the first water guide 12.

[0051] The aforementioned first setting value is determined based on the length of the second water guide 22 installed in the second water tank 21, and correspondingly, the aforementioned second setting value is determined based on the length of the first water guide 12 installed in the first water tank 11. That is, when the liquid in the second water tank 21 is above the top of the portion of the second water guide 22 installed in the second water tank 21, the liquid in the second water tank 21 flows to the first water tank 11 through the second water guide 22; when the liquid in the first water tank 11 is above the top of the portion of the first water guide 12 installed in the first water tank 11, the liquid in the first water tank 11 flows to the outside through the first water guide 12.

[0052] To enable the water diversion system 200 to automatically change water at multiple frequencies during outdoor rain to maintain the freshness of the stored liquid, the water diversion system 200 in this embodiment also includes a locking mechanism 3. The locking component is connected to the first water guide 12 and is adapted to lock or unlock the first water guide 12, so that the first water guide 12 has a conducting state and a cut-off state, thereby determining whether the liquid in the first water storage tank 11 flows to the outside. At the same time, the first water storage mechanism 1 also includes a floating component 13, which is disposed inside the first water storage tank 11 and located below the second water storage tank 21.

[0053] Please refer to the specific details. Figure 6 and Figure 7 Furthermore, the aforementioned second water tank 21 is movable along the height direction. The locking mechanism 3 includes an unlocking member 31 that contacts the second water tank 21. Changes in the liquid level within the second water tank 21 cause changes in the weight of the second water tank 21, thereby driving the unlocking member 31 to move, causing the first water guide member 12 to switch between a conducting state and a cut-off state. Thus, the water diversion system 200 forms an automatic water exchange cycle. That is, the water diversion system 200 can achieve automatic water exchange cycle without the aid of external force (such as electricity or human intervention). The specific process of the automatic water exchange cycle will be described in detail later.

[0054] In this embodiment, a sliding groove 111 is provided on the side wall of the first water storage tank 11, and a slider 23 is provided on the side wall of the second water storage tank 21. An elastic element is provided within the sliding groove 111, and the slider 23 is disposed within the sliding groove 111 and presses against the elastic element. The sliding groove 111 extends along the height direction of the first water storage tank 11. In this embodiment, the elastic element can be a spring, silicone, or other object that can undergo elastic deformation under external force.

[0055] When the liquid level in the second water tank 21 changes, the overall weight of the second water tank 21 and the liquid inside it also changes, which causes the slider 23 to press against the elastic element, so that the second water tank 21 moves relative to the first water tank 11 in the height direction.

[0056] As mentioned above, the second water tank 21 is in contact with the unlocking member 31. When the overall weight of the second water tank 21 changes, it can compress the unlocking member 31 to move, thereby causing the first water guide member 12 to switch between the conducting state and the cut-off state. That is, when the liquid level in the second water tank 21 reaches the third set value, the second water tank 21 moves downward to compress the unlocking member 31 to move.

[0057] In one embodiment, when the overall weight of the second water tank 21 changes, the unlocking member 31 can be forced to move up and down. At this time, the unlocking member 31 and the inner wall of the first water tank 11 are slidably connected. This slidable connection can be similar to the connection method of the first water tank 11 and the second water tank 21 described above, with a slot and a block. The slot is located on the inner wall of the first water tank 11, the block is located at one end of the unlocking member 31, and the other end of the unlocking member 31 contacts the lower end of the second water tank 21.

[0058] In another embodiment, when the overall weight of the second water tank 21 changes, the unlocking member 31 can be forced to rotate along the height direction. At this time, the unlocking member 31 is rotatably connected to the inner wall of the first water tank 11. This rotatable connection can be achieved by a pivot, which will not be elaborated here. In this embodiment, the unlocking member 31 is a lever, and the rotatable connection between the unlocking member 31 and the inner wall of the first water tank 11 is specifically described.

[0059] The locking mechanism 3 also includes a locking member 33 connected to the first water guide member 12, and a transmission member 32 connecting the unlocking member 31 and the locking member 33 respectively. Both ends of the transmission member 32 are fixedly connected to the locking member 33 and the unlocking member 31 respectively. In this embodiment, the transmission member 32 is a transmission rod, and the locking member 33 is a lever-type pressure reducing valve. The lever-type pressure reducing valve regulates the flow rate of the medium by controlling the opening and closing of the valve body, reducing the pressure of the medium. Simultaneously, it adjusts the opening and closing of the valve by utilizing the downstream pressure, keeping the downstream pressure within a certain range. The unlocking member 31 moves under the gravity of the second water storage tank 21, transmitting force to the locking member 33 through the transmission member 32, thereby unlocking the locking member 33.

[0060] When the first water guide 12 and the second water guide 22 are electrically powered, the locking member 33 can also be a pressure sensor, and a solenoid valve is provided to enable or disable the first water guide 12.

[0061] The floating component 13 floats according to the change in the liquid level in the first water tank 11, so that when it floats to a set position, the liquid in the first water tank 11 can flow to the outside through the first water guide 12 which is in a conductive state. The set position is a liquid level position that is higher than or equal to a second set value.

[0062] The floating component 13 includes a buoyancy plate 131 and a gravity plate 132 connected to the buoyancy plate 131 via a connector and located below the buoyancy plate 131. The gravity of the gravity plate 132 is less than the buoyancy of the liquid in the first water tank 11, so that the buoyancy plate 131 can drive the gravity plate 132 to rise when the liquid level rises, and the gravity plate 132 can drive the buoyancy plate 131 to fall under its own weight when the liquid level falls. In this embodiment, the connector is a traction rope. In other embodiments, the connector may be other types, such as a connecting column, etc., which are not specifically limited here and are determined according to the actual situation.

[0063] A flow hole 1311 is provided on the buoyancy plate 131, and the outlet end of the second water guide 22 is located above the buoyancy plate 131, so that the liquid flowing into the first water storage tank 11 flows through the flow hole 1311 to the gravity plate 132. A filter element can be provided in the flow hole 1311 to filter the liquid passing through the flow hole 1311. In this embodiment, the filter element is a filter screen.

[0064] The gravity plate 132 includes a plate body 1323, which has a hollow cavity 1321 and holes communicating with the hollow cavity 1321. The inlet end of the first water guide 12 is positioned facing the bottom wall of the first water storage tank 11 and communicating with the hollow cavity 1321. The purpose of this arrangement is that when the liquid level in the first water storage tank reaches a second preset value, the liquid at the bottom of the first water storage tank 11 flows to the outside through the first water guide 12. When the liquid in the second water storage tank 21 flows to the first water storage tank 11 through the second water guide 22, it gradually flows towards the gravity plate 132 due to the flow hole 1311 of the buoyancy plate 131, and then flows to the bottom of the first water storage tank 11 through the holes on the gravity plate 132, thereby ensuring the freshness of the liquid after water replacement.

[0065] Furthermore, as mentioned above, the second water guide 22 is an inverted U-shaped flexible hose, and the floating assembly 13 floats with the change of liquid level in the first storage tank. The water inlet end of the second water guide 22 is connected to the hollow cavity 1321 of the plate 1323. During the floating process, the floating assembly 13 will drive the water inlet end of the second water guide 22 to float. Since the second water guide 22 itself is a flexible hose, it will not obstruct the floating of the floating assembly 13.

[0066] The gravity plate 132 also includes scraping members 1322 connected to both ends of the plate body 1323. When the plate body 1323 floats up and down with the buoyancy plate 131, the scraping members 1322 are suitable for scraping and cleaning the inner wall of the first water storage tank 11. In this embodiment, the scraping member 1322 is a scraper. The dirt scraped by the scraping member 1322 flows through the holes to the lower part of the plate body 1323 under the floating action of the plate body 1323, and flows with the liquid through the holes into the hollow cavity 1321 under the suction action of the first water guide member 12, until it flows to the outside. As can be seen from the foregoing, the first water guide member can generate a siphon effect. Therefore, the suction force of the first water guide member 12 is a siphon force.

[0067] As can be seen, the overall automatic water exchange process of the water diversion system 200 in this embodiment is as follows: the water collection tank 301 delivers liquid to the second water storage tank 21 through the conduit 302. When the liquid in the second water storage tank 21 reaches the first set value, it flows to the first water storage tank 11 through the second water guide 22. When the liquid in the first water storage tank 11 reaches the second set value, it flows to the first water guide 12, which is locked by the locking mechanism 3 to be in a closed state. When the liquid level in the second water storage tank 21 reaches the third set value, it presses the unlocking member 31 to move, causing the first water guide 12 to switch to the open state, and the liquid in the first water storage tank 11 flows to the outside through the first water guide 12.

[0068] The third setting value is greater than or equal to the first setting value, and the first setting value is greater than or equal to the second setting value. The first, second, and third setting values ​​can be set according to actual conditions. As mentioned above, the first setting value is determined by the length of the second water guide 22 installed in the second water tank 21, and correspondingly, the second setting value is determined by the length of the first water guide 12 installed in the first water tank 11. In other embodiments, the first and second setting values ​​can also be set to one-fifth of the overall height of the first water tank 11, and the third setting value can be set to one-fifth of the overall height of the first water tank 11, or greater than one-fifth, thereby achieving automatic water replacement of one-fifth of the first water tank 11 to ensure the freshness of the liquid in the first water tank 11.

[0069] In summary: The system comprises a first water storage mechanism 1, a second water storage mechanism 2, and a locking mechanism 3. The first water storage mechanism 1 includes a first water storage tank 11 and a first water guide 12 connecting the first water storage tank 11 to the outside. The second water storage mechanism 2 includes a second water storage tank 21 disposed within the first water storage tank 11 and a second water guide 22 connecting the first water storage tank 11 and the second water storage tank 21. The second water storage tank 21 is connected to an external water collection device 100. The locking mechanism 3 is connected to the first water guide 12 to switch between a conducting state and a cut-off state, and the unlocking part 31 of the locking mechanism 3 contacts the second water storage tank 21. The external water collection device 100 supplies liquid to the second water storage tank 21. When the liquid level in the second water storage tank 21 reaches a first preset value, the liquid can be released. The liquid flows through the second water guide 22 to the first water storage tank 11. When the liquid level in the first water storage tank 11 reaches the second preset value, the liquid can flow to the first water guide 12, which is in a closed state. When the liquid level in the second water storage tank 21 reaches the third preset value, the second water storage tank 21 can press the unlocking member 31 to move, so that the first water guide 12 switches to the open state, and then the liquid in the first water storage tank 11 flows to the outside. Thus, the liquid in the external water collection device 100 flows to the second water storage tank 21, the liquid in the second water storage tank 21 flows to the first water storage tank 11, and the liquid in the first water storage tank 11 flows to the outside, forming an automatic water exchange process to ensure the freshness of the liquid in the first water storage tank 11, thereby meeting the corresponding planting and breeding needs, which is convenient and fast.

Claims

1. A closed balcony ecological aquaculture water supply system, characterized in that, include: The first water storage mechanism includes a first water storage tank and a first water guide component connecting the first water storage tank and the outside. The second water storage mechanism includes a second water storage tank connected to an external water collection device, and a second water guide connecting the first water storage tank and the second water storage tank. The second water storage tank is disposed inside the first water storage tank and can move along the height direction. A locking mechanism, connected to the first water guide, is adapted to lock or unlock the first water guide so that the first water guide has a conducting state and a cut-off state; the locking mechanism includes an unlocking member that contacts the second water tank, and the liquid level change in the second water tank causes the weight of the second water tank to change, thereby driving the unlocking member to move so that the first water guide switches between the conducting state and the cut-off state. When the liquid level in the second water tank reaches a first set value, it flows through the second water guide to the first water tank. When the liquid level in the first water tank reaches a second set value, it flows into the first water guide. The first water guide is locked by the locking mechanism to be in the cut-off state. When the liquid level in the second water tank reaches a third set value, it presses the unlocking member to move, causing the first water guide to switch to the open state. The liquid in the first water tank then flows to the outside through the first water guide. The first water storage mechanism further includes a floating component, which is disposed inside the first water storage tank and located below the second water storage tank; The floating component floats with the change of liquid level in the first water tank, so that when it floats to a set position, the liquid in the first water tank can flow to the outside through the first water guide in the conducting state. The set position is a liquid level position that is higher than or equal to the second set value; The floating component includes a buoyancy plate and a gravity plate connected to the buoyancy plate via a connector and located below the buoyancy plate; The gravity of the gravity plate is less than the buoyancy of the liquid in the first water tank; The buoyancy plate is provided with flow holes; The outlet end of the second water guide is located above the buoyancy plate, so that the liquid flowing into the first water tank flows through the flow hole to the gravity plate; The gravity plate includes a plate body and scraping components connected to both ends of the plate body. When the plate body floats up and down with the buoyancy plate, the scraping components are adapted to scrape and clean the inner wall of the first water storage tank. The plate has a hollow cavity and holes communicating with the hollow cavity; The inlet end of the first water guide is positioned facing the bottom wall of the first water storage tank and is connected to the hollow cavity. The dirt scraped by the scraper flows to the bottom of the plate under the floating action of the plate, and flows into the hollow cavity with the liquid through the holes under the suction action of the first water guide until it flows to the outside.

2. The enclosed balcony ecological aquaculture water supply system according to claim 1, characterized in that: The locking mechanism further includes a locking component connected to the first water guide component, and a transmission component that connects the unlocking component and the locking component respectively; The unlocking component moves under the gravity of the second water tank to transmit force to the locking component through the transmission component, thereby unlocking the locking component.

3. The enclosed balcony ecological aquaculture water supply system according to claim 2, characterized in that: The locking element is a lever-type pressure reducing valve or a pressure sensor.

4. The enclosed balcony ecological aquaculture water supply system according to any one of claims 1 to 3, characterized in that: The first water guide and the second water guide are inverted U-shaped hoses, with the end of the inverted U-shaped hose immersed in the liquid located above the other end that is not immersed in the liquid along the height direction.

5. The enclosed balcony ecological aquaculture water supply system according to any one of claims 1 to 3, characterized in that: The third setting value is greater than or equal to the first setting value, and the first setting value is greater than or equal to the second setting value.
