Description

Technical Field

[0001] The utility model relates to the field of fish tanks, in particular to a tidal tank. Background Art

[0002] The main function of the tidal tank is to simulate the natural environment of the intertidal zone at the seaside so as to better cultivate intertidal organisms such as fiddler crabs, mudskippers, mangroves, and saltwort.

[0003] The tidal cylinder consists of a main cylinder and a filter cylinder. The water in the main cylinder flows into the filter cylinder (this is the main cylinder water discharge), and the water filtered by the filter cylinder flows back into the main cylinder (this is the main cylinder water supply). When the water discharge flow rate of the main cylinder is greater than the water supply flow rate, the main cylinder forms a low tide. When the water discharge flow rate of the main cylinder is less than the water supply flow rate, the main cylinder forms a high tide. When the water discharge flow rate of the main cylinder is balanced with the water supply flow rate, the main cylinder is maintained at a high tide or low tide.

[0004] The invention patent application with application number 202410122420 discloses a tidal cylinder, which includes a main cylinder 1a, a water pump 2a, a filter cylinder 3a, an air chamber 4a, a venturi ejector 5a, an upper water pipe 6a, a lower water pipe 7a, an exhaust pipe 8a, an air intake pipe 9a, a first electric ball valve 10a, and a second electric ball valve 11a. When the tide begins to rise, the first electric ball valve 10a is in an open state, and negative pressure is generated at the air intake end of the venturi ejector 5a under the action of the water pump 2a. The outside air will enter the venturi ejector 5a through the air intake pipe 9a, and spray into the air chamber 4a from the outlet of the venturi ejector 5a. Since the second electric ball valve 11a is in a closed state at this time and the exhaust pipe 8a is not connected, the air injected into the air chamber 4a will float above the air chamber 4a, thereby pressing the water in the air chamber 4a into the tidal area outside the air chamber 4a, and the tidal area will achieve a preliminary high tide. After a preset time, the first electric ball valve 10a is closed, and the second electric ball valve 11a remains closed. The gas in the air chamber 4a no longer increases, and the water pump 2a pumps the water in the filter cylinder 3a into the main cylinder 1a. The tidal area in the main cylinder 1a continues to rise until the water intake in the main cylinder 1a is equal to the water discharge, and the tidal area in the main cylinder 1a reaches a high tide level.

[0005] At the initial high tide, the first electric ball valve 10a is in the open state, and part of the power of the water pump 2a is converted into the suction force of the air intake end of the venturi ejector 5a, which is used to inhale the outside air and transport the inhaled air to the air chamber 4a. At this time, only a small amount of water in the filter cylinder 3a is pumped into the main cylinder 1a by the water pump 2a. When the tide continues to rise, high tide, low tide and low tide, the first electric ball valve 10a is in the closed state, and the power of the water pump 2a pumps the water in the filter cylinder 3a into the main cylinder 1a. However, due to the narrow internal channel of the venturi ejector 5a, it will hinder the water flow, causing flow loss of the water pump 2a.

[0006] Therefore, how to reduce the flow loss of the water pump during continued high tide, high tide, low tide and low tide is a key issue that needs to be urgently solved by technical personnel in this field. Utility Model Content

DETAILED DESCRIPTION

[0038] In view of this, the core of the present invention is to reduce the flow loss of the water pump during continuous high tide, high tide, low tide and low tide.

[0039] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] Please refer to the attached Figure 2 -Attached Figure 6The tidal cylinder in the utility model includes a main cylinder 2, a filter cylinder 1, an air chamber 5, an overflow downpipe, a water pump 16, a water supply pipe, an air intake pipe 7, an exhaust pipe 6, a second electric ball valve 12, and a venturi ejector 10. The air chamber 5 is arranged in the main cylinder 2, and the part of the main cylinder 2 outside the air chamber 5 is the tidal zone. The bottom of the air chamber 5 is provided with a channel, which connects the air chamber 5 and the tidal zone. The overflow downpipe includes an overflow pipe 401 and a downpipe. The overflow pipe 401 is located in the tidal zone, and the core tube of the overflow pipe 401 extends from the bottom of the main cylinder 2. The water outlet end of the core tube is connected to the water inlet end of the downpipe, and the water outlet end of the downpipe is connected to the filter cylinder 1. The overflow pipe 401 forms an overflow in the tidal zone. The water in the tidal zone first enters between the outer tube and the core tube of the overflow pipe 401 from the bottom and the top of the overflow pipe 401, then enters the core tube through the upper port of the core tube, and then enters the filter tank 1 through the downpipe. The bottom and the top of the overflow pipe 401 are both provided with fish intercepting combs. The water enters between the outer tube and the core tube of the overflow pipe 401 through the fish intercepting combs at the bottom and the top of the overflow pipe 401.

[0041] The water pump 16 is arranged in the filter cylinder 1, and the water outlet end of the water pump 16 is connected to the upper water pipe. The venturi ejector 10 is arranged in the upper water pipe, and the outlet end of the venturi ejector 10 is connected to the air chamber 5, and the suction end of the venturi ejector 10 is connected to the suction pipe 7.

[0042] One end of the exhaust pipe 6 is connected to the air chamber 5, and the other end of the exhaust pipe 6 is connected to the outside atmosphere. The second electric ball valve 12 is arranged on the exhaust pipe 6. A regulating valve can also be arranged on the exhaust pipe 6 to adjust the exhaust speed of the exhaust pipe 6. The suction pipe 7 can conduct or block the outside atmosphere and the suction end of the venturi ejector 10.

[0043] The water supply pipe includes a first water supply main pipe 301, a first water supply branch pipe, a second water supply branch pipe, a first electric ball valve 11 and a second water supply main pipe 302. The water inlet end of the first water supply main pipe 301 is connected to the water outlet end of the water pump 16, and the water outlet end of the first water supply main pipe 301 is connected to the first water supply branch pipe and the second water supply branch pipe. The venturi ejector 10 is arranged on the first water supply branch pipe, the first electric ball valve 11 is arranged on the second water supply branch pipe, the water outlet end of the first water supply branch pipe and the water outlet end of the second water supply branch pipe are both connected to the second water supply main pipe 302, and the second water supply main pipe 302 is connected to the air chamber 5.

[0044] If the tidal zone of the main cylinder 2 is currently at a low tide, the initial tide and the continued tide will be carried out next. At the initial tide, the first electric ball valve 11 is closed, and the water pump 16 pumps the water in the filter cylinder 1 into the first water main pipe 301. Since the second water branch pipe is cut off, the water in the first water main pipe 301 flows into the first water branch pipe. When passing through the venturi ejector 10, the air suction end of the venturi ejector 10 generates obvious suction, thereby sucking the outside air into the venturi ejector 10 through the air suction pipe 7, and then the outlet of the venturi ejector 10 sprays the sucked air into the air chamber 5. Since the second electric ball valve 12 is in a closed state at this time, the air in the air chamber 5 cannot be discharged through the exhaust pipe 6, so the air in the air chamber 5 will float to the top of the air chamber 5, and the floating air will press the water in the air chamber 5 into the tidal zone, and the tidal zone will have an initial tide.

[0045] After the preset time, the first electric ball valve 11 on the second water supply branch pipe is opened. Since the resistance of water flowing through the first electric ball valve 11 is much smaller than the resistance of water flowing through the venturi ejector 10, most of the water will flow into the second water supply branch pipe and enter the main cylinder 2. At this time, the second electric ball valve 12 remains closed, the air in the air chamber 5 is sealed at the top of the air chamber 5, the liquid level in the air chamber 5 remains unchanged, and the water pumped into the air chamber 5 flows into the tidal area through the channel at the bottom of the air chamber 5. The liquid level in the tidal area continues to rise, and the tidal area continues to rise.

[0046] In the invention patent application with application number 202410122420, at high tide, high tide, low tide, and low tide, all the water from the first water main pipe 301 passes through the venturi ejector 10, and the water flow is significantly resisted by the venturi ejector 10, causing significant flow loss of the water pump 16. In the present utility model, at continued high tide, high tide, low tide, and low tide, most of the water flowing out of the first water main pipe 301 will flow through the second water branch pipe, and only a small amount of water will flow through the first water branch pipe, that is, only a small amount of water will be resisted by the venturi ejector 10, so the present utility model significantly reduces the flow loss of the water pump 16 at continued high tide, high tide, low tide, and low tide.

[0047] In the invention patent application with application number 202410122420, an electric ball valve is provided on the suction pipe 7. At the initial high tide, the electric ball valve on the suction pipe 7 is opened, and the outside air enters the Venturi ejector 10 through the suction pipe 7, and is finally ejected from the outlet of the Venturi ejector 10 into the air chamber 5. After the initial high tide, the electric ball valve on the suction pipe 7 is closed, and the water pump 16 pumps the water in the filter cylinder 1 into the air chamber 5. Although the electric ball valve on the suction pipe 7 is in a closed state at this time, a small amount of air still enters the Venturi ejector 10 through the valve core gap of the electric ball valve, which will generate bubbles in the air chamber 5, affecting the ornamental value of the tidal cylinder.

[0048] In order to avoid the generation of bubbles, a side pipe 8 is provided on the suction pipe 7 in the invention patent application with application number 202410122420. One end of the side pipe 8 is connected to the suction pipe 7, and the other end opens downward and is connected to the tidal zone. When the tide continues to rise, high tide, ebb tide and low tide, part of the negative pressure at the suction end of the venturi ejector 10 will transport the water sucked by the side pipe 8 into the air chamber 5, and the other part of the negative pressure will act on the electric ball valve on the suction pipe 7, sucking a trace of air from the gap of the valve core of the electric ball valve, and the trace air will form bubbles in the air chamber 5. Therefore, even if the side pipe 8 is provided, trace bubbles are still inevitably generated.

[0049] In the present invention, a first water supply branch pipe and a second water supply branch pipe are provided. When the first electric ball valve 11 on the second water supply branch pipe is opened, most of the water from the first water supply main pipe 301 will choose to flow through the second water supply branch pipe, and only a small part of the water will flow through the venturi ejector 10. At this time, the suction force of the air intake end of the venturi ejector 10 is relatively small, and it is impossible to suck all the water in the air intake pipe 7 into the venturi ejector 10. A section of water column will remain in the air intake pipe 7, and this section of water column will form a water seal, thereby effectively preventing the outside air from entering the venturi ejector 10, and further effectively preventing the generation of bubbles in the air chamber 5.

[0050] In the utility model, the arrangement of the second water supply branch pipe and the first electric ball valve 11 not only significantly reduces the flow loss of the water pump 16 during continued high tide, high tide, low tide and low tide, but also during continued high tide, high tide, low tide and low tide, since the suction force at the suction end of the Venturi ejector 10 is relatively small and insufficient to lower the water level in the suction pipe 7 to the height of the ejector suction end, a section of water column will remain in the suction pipe 7 to form a water seal, thereby effectively preventing the generation of bubbles in the air chamber 5.

[0051] The utility model is provided with a first regulating valve 9 on the side pipe 8, and the first regulating valve 9 is used to adjust the opening of the side pipe 8. During the initial tide rising process, a large part of the suction force of the suction end of the venturi ejector 10 is to inhale the air from the outside, and another small part will act on the side pipe 8, and the water in the tidal zone will be inhaled through the side pipe 8. If the opening of the first regulating valve 9 is increased during the initial tide rising, a large amount of water will enter the suction pipe 7 through the side pipe 8, and the amount of air entering will be reduced, thereby slowing down the speed of the initial tide rising. If the opening of the first regulating valve 9 is reduced during the initial tide rising, a small amount of water will enter the suction pipe 7 through the side pipe 8, and the amount of air entering will be increased, thereby accelerating the speed of the initial tide rising.

[0052] When there are small creatures such as fish and shrimp in the tidal zone, these small creatures may drill into the side pipe 8, causing the side pipe 8 to be blocked. In order to prevent the small creatures from blocking the side pipe 8, in the specific embodiment of the utility model, a fish blocking net 18 is set at the downward opening of the side pipe 8.

[0053] Next, three specific structures of the first water supply branch pipe and the second water supply branch pipe are introduced: the first structure: the water outlet end of the first water supply main pipe 301 is connected to the pipe body of the first horizontal pipe 304, the two ends of the first horizontal pipe 304 are respectively connected to the bottom end of the first vertical pipe 307 and the bottom end of the second vertical pipe 306, the second vertical pipe 306 is close to the air chamber 5 relative to the first vertical pipe 307, the top of the first vertical pipe 307 and the top of the second vertical pipe 306 are connected to the two ends of the second horizontal pipe 305, and the intersection of the top of the second vertical pipe 306 and the second horizontal pipe 305 is connected to the water inlet end of the second water supply main pipe 302.

[0054] The pipe between the outlet end of the first water supply main pipe 301 and the bottom end of the first vertical pipe 307, the first vertical pipe 307 and the second horizontal pipe 305 constitute the first water supply branch pipe. The pipe between the outlet end of the first water supply main pipe 301 and the bottom end of the second vertical pipe 306 and the second vertical pipe 306 constitute the second water supply branch pipe. The venturi ejector 10 is arranged on the second horizontal pipe 305, and the first electric ball valve 11 is arranged on the first horizontal pipe 304.

[0055] Please refer to the attached Figure 2 , 3 , 4, 5, 6, in the first structure, the water from the first water main pipe 301 will be divided into left and right after entering the first horizontal pipe 304, the water flow to the right will flow into the water inlet end of the venturi ejector 10, and the water flow to the left will flow into the outlet end of the venturi ejector 10. Since the water flow at the water inlet end and the water flow at the outlet end of the venturi ejector 10 are relatively close, the water flow has little effect on the suction end of the venturi ejector 10.

[0056] Please refer to the attached Figure 7 , attached Figure 7The second structure of the first water supply branch pipe and the second water supply branch pipe is shown: the water outlet of the first water supply main pipe 301 is connected to the bottom end of the third vertical pipe 310, and the water inlet of the third horizontal pipe 308 is connected to the bottom end of the third vertical pipe 310. The water outlet of the third horizontal pipe 308 is connected to the bottom end of the fourth vertical pipe 309, and the top of the fourth vertical pipe 309 and the top of the third vertical pipe 310 are respectively connected to the two ends of the fourth horizontal pipe 311, and the fourth vertical pipe 309 is close to the air chamber 5 relative to the third vertical pipe 310. The intersection of the fourth vertical pipe 309 and the fourth horizontal pipe 311 is connected to the water inlet of the second water supply main pipe 302. The venturi ejector 10 is arranged on the fourth horizontal pipe 311, and the first electric ball valve 11 is arranged on the third horizontal pipe 308. The third vertical pipe 310 and the fourth horizontal pipe 311 constitute a first water supply branch pipe, and the third horizontal pipe 308 and the fourth vertical pipe 309 constitute a second water supply branch pipe.

[0057] Please continue to refer to the attached Figure 7 In the second structure, when the water from the first water main 301 flows through the intersection of the third horizontal pipe 308 and the third vertical pipe 310, under the action of inertia, more water will choose to enter the third vertical pipe 310. Compared with the first structure, more water will flow through the water inlet end of the Venturi ejector 10 in the second structure, which will increase the suction force of the suction end of the Venturi ejector 10. This structure is suitable for Venturi ejectors 10 with too weak suction. For Venturi ejectors 10 with too weak suction, when the first electric ball valve 11 is opened, since the suction force at the suction end of the Venturi ejector 10 is relatively weak, the liquid level in the suction pipe 7 will be relatively high, and it may overflow from the suction pipe 7. The second structure in this embodiment increases the suction force at the suction end of the Venturi ejector 10, thereby avoiding the excessive height of the water column liquid level in the suction pipe 7.

[0058] Please refer to the attached Figure 8 , attached Figure 8The third structure of the first water supply branch pipe and the second water supply branch pipe: the first water supply main pipe 301 includes a first vertical water supply main pipe and a first horizontal water supply main pipe. The bottom end of the first vertical water supply main pipe is connected to the water outlet of the water pump 16, the top end of the first vertical water supply main pipe is connected to the water inlet of the first horizontal water supply main pipe, and the water outlet of the first horizontal water supply main pipe is connected to the bottom end of the sixth vertical pipe 315. The top end of the sixth vertical pipe 315 is connected to the water inlet of the second water supply main pipe 302, the pipe body of the sixth vertical pipe 315 is connected to the water inlet of the fifth horizontal pipe 312, and the water outlet of the fifth horizontal pipe 312 is connected to the bottom end of the fifth vertical pipe 314. The fifth horizontal pipe 312 is located above the first horizontal water supply main pipe. The fifth vertical pipe 314 is far away from the air chamber 5 relative to the sixth vertical pipe 315, the water inlet end of the sixth horizontal pipe 313 is connected to the top of the fifth vertical pipe 314, and the water outlet end of the sixth horizontal pipe 313 is connected to the water inlet end of the second water supply main pipe 302. The water outlet end of the sixth horizontal pipe 313, the water outlet end of the sixth vertical pipe 315 and the water inlet end of the second water supply main pipe 302 intersect. The venturi ejector 10 is arranged on the sixth horizontal pipe 313, the first electric ball valve 11 is arranged on the sixth vertical pipe 315, and the first electric ball valve 11 is located between the sixth horizontal pipe 313 and the fifth horizontal pipe 312. The fifth horizontal pipe 312, the fifth vertical pipe 314 and the sixth horizontal pipe 313 constitute the first water supply branch pipe. The sixth vertical pipe 315 is the second water supply branch pipe.

[0059] In the third structure, the water flow will face diversion after flowing to the sixth vertical pipe 315. One stream of water will enter the fifth horizontal pipe 312, and the other stream of water will still flow upward along the sixth vertical pipe 315. However, since the water flow in the sixth vertical pipe 315 has the inertia of flowing upward, more water will flow upward, and less water will enter the fifth horizontal pipe 312. More water will flow upward along the sixth vertical pipe 315 and pass through the outlet of the Venturi ejector 10, thus reducing the suction force of the suction end of the Venturi ejector 10. This structure is suitable for Venturi ejectors 10 with too strong suction force. For the Venturi ejector 10 with too strong suction force, after the first electric ball valve 11 is opened, the negative pressure at the suction end of the Venturi ejector 10 is relatively large, resulting in a low liquid level in the suction pipe 7, and even completely sucking the water column in the suction pipe 7 into the Venturi ejector 10, thereby causing outside air to enter the Venturi ejector 10. In the third structure, the water flow at the water outlet end of the sixth vertical pipe 315 increases the positive pressure at the suction end of the Venturi ejector 10 and weakens the negative pressure at the suction end, thereby preventing the water column liquid level in the suction pipe 7 from being too low.

[0060] As can be seen from the above description, a side pipe 8 is provided on the pipe body of the air intake pipe 7, one end of the side pipe 8 is connected to the air intake pipe 7, and the other end is open downward and connected to the tidal zone. For a Venturi ejector 10 with too weak suction, if the water column in the air intake pipe 7 is too high, a part of the water in the air intake pipe 7 will flow into the tidal zone through the side pipe 8, which is conducive to lowering the liquid level of the water column in the air intake pipe 7. For a Venturi ejector 10 with too strong suction, if the water column in the air intake pipe 7 is too low, a part of the water in the tidal zone will flow into the air intake pipe 7 through the side pipe 8 to increase the liquid level of the water column in the air intake pipe 7.

[0061] In the specific embodiment of the utility model, the second water supply main pipe 302 is set as a shower pipe, and a plurality of shower holes arranged along the axial direction of the shower pipe are set on the shower pipe. During the initial high tide, the air sucked from the air intake pipe 7 is ejected from the nozzle of the venturi ejector 10, and then evenly distributed in the shower pipe along the length direction of the shower pipe, and then ejected from each shower hole and floated up steadily. In the process of air being evenly distributed in the shower pipe, a certain impact force will be consumed, so that the air flow ejected from the shower hole is relatively gentle.

[0062] The opening of the shower hole faces upward or obliquely upward. In addition, the utility model provides an elbow 303 at the end of the shower pipe, and the end opening of the elbow 303 faces upward or obliquely upward. Such a configuration can ensure that the water flow or air flow sprayed from the shower hole and the end opening of the elbow 303 faces upward or obliquely upward to avoid dispersing the bottom sand at the bottom of the master cylinder 2.

[0063] In the specific embodiment of the utility model, the air inlet end of the air intake pipe 7 and the exhaust end of the exhaust pipe 6 are both connected to the main air pipe, and the main air pipe is provided with a muffler 14. That is, the air intake pipe 7 and the exhaust pipe 6 share a main air pipe and a muffler 14, which simplifies the structural setting.

[0064] It can be seen from the above description that the overflow sewer pipe includes an overflow pipe 401 and a sewer pipe. The sewer pipe also includes a first sewer main pipe 402, a first sewer branch pipe 404, a second sewer branch pipe 403 and a second sewer main pipe 405. The core pipe of the overflow pipe 401 extends from the bottom of the main cylinder 2, and the bottom end of the core pipe is connected to the water inlet end of the first sewer main pipe 402, and the water outlet end of the first sewer main pipe 402 is simultaneously connected to the water inlet end of the first sewer branch pipe 404 and the water inlet end of the second sewer branch pipe 403. The water outlet end of the first sewer branch pipe 404 and the water outlet end of the second sewer branch pipe 403 are both connected to the water inlet end of the second sewer main pipe 405. The water outlet end of the second sewer main pipe 405 is connected to the filter cylinder 1. The first sewer branch pipe 404 is provided with a third electric ball valve 13, and the second sewer branch pipe 403 is provided with a second regulating valve.

[0065] The second regulating valve is a normally open valve. At high tide, the third electric ball valve 13 remains closed, and only the second drainage branch pipe 403 remains unobstructed to ensure that the upstream flow is greater than the downstream flow. At low tide, the third electric ball valve 13 opens to increase the downstream flow, so that the downstream flow is greater than the upstream flow.

[0066] A float valve 15 is provided at the intersection of the core tube of the overflow pipe 401 and the first main sewer pipe 402, and the float of the float valve 15 is located in the filter tank 1. During the ebb of the tidal zone, the water level in the filter tank 1 gradually rises, and the float floating on the water surface of the filter tank 1 rises with the rise of the water level, and the opening of the float valve 15 decreases, which is conducive to reducing the flow rate of the sewer, thereby balancing the flow rate of the upstream water and the flow rate of the downstream water to form a low tide.

[0067] In the event of an unexpected power outage, the water pump 16 stops operating, and the filter cylinder 1 only takes in water but does not discharge water. When the water level in the filter cylinder 1 rises to a certain level, the float valve 15 will be blocked, thereby preventing the main cylinder 2 from further overflowing into the filter cylinder 1, thereby preventing the water in the filter cylinder 1 from overflowing.

[0068] In addition, the utility model also provides a check valve 17 on the first water supply main pipe 301 to prevent the water in the master cylinder 2 from flowing back into the water pump 16 along the water supply pipe when an unexpected power outage occurs.

[0069] The first electric ball valve 11, the second electric ball valve 12 and the third electric ball valve 13 in the utility model are all normally open valves. The first electric ball valve 11, the second electric ball valve 12 and the third electric ball valve 13 are all connected to the power supply through the timing switch, and the power supply line of the first electric ball valve 11 is also provided with a power-on delay closing switch module.

[0070] Next, we will introduce the tidal process of the tidal tank:

[0071] Initial high tide, please refer to the attached Figure 3 : The timing switch is powered on, the first electric ball valve 11, the second electric ball valve 12 and the third electric ball valve 13 are all closed, part of the power of the water pump 16 is converted into the suction force of the suction end of the venturi ejector 10, the outside air is sucked into the venturi ejector 10, the air is ejected from the outlet end of the venturi ejector 10 and enters the second water supply main pipe 302, and finally ejected from the second water supply main pipe 302 into the air chamber 5. The water level in the air chamber 5 drops, and the water level in the tidal zone rises, forming a preliminary high tide.

[0072] The tide continues to rise, please refer to the attached Figure 4:The timing switch remains powered on, and the first electric ball valve 11, the second electric ball valve 12 and the third electric ball valve 13 remain closed. After a certain amount of air is filled into the air chamber 5, the power-on delay closing module in the first electric ball valve 11 is automatically powered off, the first electric ball valve 11 is opened, and the second electric ball valve 12 and the third electric ball valve 13 remain closed. At this time, the main function of the water pump 16 is to pump the water in the filter cylinder 1 into the air chamber 5 through the second water supply branch pipe, and the water pumped into the air chamber 5 will flow into the tidal zone through the channel at the bottom of the air chamber 5. Since only a small part of the water pumped by the water pump 16 is hindered by the Venturi ejector 10, the water supply flow rate is relatively large, the water level in the filter cylinder 1 begins to drop significantly, and the water level in the tidal zone of the main cylinder 2 continues to rise, forming a continued high tide.

[0073] For high tide position, please refer to the attached Figure 5 : The timer switch remains powered on, the first electric ball valve 11 remains open, and the second electric ball valve 12 and the third electric ball valve 13 remain closed. The water level in the filter tank 1 continues to decrease, and the water supply of the water pump 16 gradually decreases. When the water supply and water supply in the main tank 2 are balanced, the water level in the tidal zone reaches the high tide level.

[0074] Low tide, please refer to the attached Figure 6 : The timer switch is powered off, the first electric ball valve 11 remains open, and the second electric ball valve 12 and the third electric ball valve 13 are both open. The exhaust pipe 6 is connected, and the air at the top of the air chamber 5 is discharged to the atmosphere through the exhaust pipe 6. The water level in the air chamber 5 rises, and the water level in the tidal zone drops. At the same time, since the third electric ball valve 13 is opened, the first water branch pipe 404 and the second water branch pipe 403 are both used for water discharge, and the water discharge in the main cylinder 2 is greater than the water supply, which further causes the water level in the tidal zone to drop, thereby forming a low tide.

[0075] For low tide levels, please refer to the attached Figure 2 : The timing switch remains in the power-off state, and the first electric ball valve 11, the second electric ball valve 12 and the third electric ball valve 13 all remain in the open state. As the liquid level in the tidal area drops, the amount of water discharged from the overflow sewer pipe gradually decreases. At the same time, as the water level in the filter cylinder 1 rises, the flow rate of the water pump 16 increases, that is, the water supply flow rate increases. When the water supply flow in the main cylinder 2 is balanced with the water supply flow, the tidal area of ​​the main cylinder 2 reaches a low tide level.
