[0028] As can be seen from the above technical solutions, the utility model discloses a water-land tidal tank, which comprises a main tank, a bottom filter system and a water circulation system, wherein a tidal pool and an overhead filter isolation layer are arranged in the main tank, the tidal pool is in a state of always having water, the overhead filter isolation layer is arranged at the bottom of the main tank, the land area isolated from the tidal pool is formed above the overhead filter isolation layer, the land area is formed by laying one or more of sand, a mixture of beach mud and sand and pure beach mud, water can penetrate downward in the land area, a water circulation area is formed below the overhead filter isolation layer, the water circulation area is used to keep water in the main tank and the bottom filter system in a filtering circulation state during the process of tide rising and falling, so that the nitrification system is prevented from collapsing, the bottom filter system is arranged below the main tank, the bottom filter system comprises a water inlet end and a water outlet end, and the water circulation system is used to connect the bottom filter system and the main tank, the water circulation system comprises a sewer pipe and a water supply device, the sewer pipe is connected between the water circulation area and the water inlet end of the bottom filter system, and the water supply device selectively connects the water outlet end of the bottom filter system with the water circulation area and the tidal pool.

[0029] When the tide rises, the water inlet device of the water circulation system is in action, and the water outlet end of the bottom filter system is communicated with the water circulation area and the tidal pool at the same time, so that the water in the bottom filter system is sent into the tidal pool. When the tidal pool is full of water, the water overflows to the land area through the upper edge of the tidal pool. Since the tidal pool buffers the impact force of the water flow, it will not cause strong impact on the sand and mud of the land area, so as to ensure that the sand and mud remain in place, forming a stable mudflat environment. The water flowing into the land area slowly penetrates downward through the laid object. At this time, the water inlet speed is greater than the water outlet speed, so the water level in the land area of the main cylinder rises until the water level in the land area of the main cylinder reaches the high tide level. At this time, since the water level in the main cylinder is at the high tide level, the water outlet speed increases, the water inlet device lift increases, the water inlet speed decreases, and the water inlet speed is equal to the water outlet speed. The water level in the main cylinder is stable at the high tide level. When the tide needs to recede, the water inlet device flow is reduced, and the water inlet device is only communicated with the water circulation area. The main cylinder stops water inlet, but the water outlet through penetration is maintained. The water level starts to drop from the high tide level, and finally the land area is exposed, reaching the complete ebb tide state. However, the laid object can still maintain a semi-moist to moist state, and there is still water in the tidal pool, so it can meet the needs of crabs, mudskippers and other organisms in the intertidal zone.

[0030] It can be seen that the size of the tidal pool can be adjusted according to the size of the main cylinder and the type of the organisms to be raised, so as to minimize the area of the tidal pool while meeting the breeding requirements, increase the area of the land area, mainly meet the needs of organisms in the intertidal zone, such as various crabs, mudskippers and other organisms, and meet the needs of a small amount of fish breeding in the tidal pool on the sea, such as gobies and other fish. The water-land tidal tank in the present application has simple structure and low complexity, and is easy to miniaturize. BRIEF DESCRIPTION OF DRAWINGS

[0049] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0050] Please refer to Figure 1 , Figure 1 The structure schematic view of water and land tidal jar provided for the first embodiment of the utility model.

[0051] The utility model embodiment discloses a kind of water and land tidal jar, and the water and land tidal jar includes main cylinder 1, bottom filter system 5 and water circulation system.

[0052] Wherein, main cylinder 1 includes but is not limited to glass jar, acrylic jar, plastic box, plastic bucket, cement pool, and main cylinder 1 is provided with tidal pool 2 and overhead filter isolation layer 3, tidal pool 2 can be integrated with main cylinder 1, also can be set in main cylinder 1 using detachable connection mode, tidal pool 2 is in water state all the time, to facilitate intertidal zone organism to enter and exit tidal pool 2, at least one side wall of tidal pool 2 can be inclined to form slope, to facilitate intertidal zone organism to enter and exit tidal pool 2, or also can be set on at least one side wall of tidal pool 2 grid, rough stone etc., to facilitate intertidal zone organism to climb in and out of tidal pool 2.

[0053] An aerial filter isolation layer 3 is arranged at the bottom of the main cylinder 1, and a land area 101 for being isolated from the tidal pool 2 is formed above the aerial filter isolation layer 3, and a water circulation area 102 is formed below the aerial filter isolation layer 3, the aerial filter isolation layer 3 supports the laying object 13 under the condition of ensuring that water can pass through, so as to avoid the laying object 13 flowing into the bottom filter system 5 and the water circulation area 102 with water, and a sealing structure 4 is arranged between the periphery of the aerial filter isolation layer 3 and the cylinder wall of the main cylinder 1. The land area 101 is formed by one or more of sand, a mixture of beach mud and sand, and pure beach mud, and can be used for water infiltration, and the laying object 13 is generally laid by the user, and the water-land tidal cylinder is mainly used for breeding intertidal zone organisms, and a laying object 13 with sufficient thickness is required to meet the digging and hiding habits of the organisms, and the water inflow and outflow speed is ensured to meet the requirements of the tide rising and falling, and the water circulation area 102 is used for keeping the water in the main cylinder 1 and the bottom filter system 5 in filtration circulation during the tide rising and falling, so as to avoid the collapse of the nitrification system, and plants such as mangroves can be planted in the laying object 13 to assist the bottom filter system 5 in absorbing harmful substances in the cylinder.

[0054] As shown in the embodiment of the present application, Figure 2 The lower layer of the laying object 13 is a sand layer 1301 formed by clean sand, the left side above the sand layer 1301 is a mud layer 1303, and the right side is a sand-mud mixed layer 1302, the sand-mud mixed layer 1302 is a mixture of sand and beach mud (the proportion is not fixed, and can be from 4:1 to pure sand, generally 8:1), and a part of the upper layer can be left out to lay a pure beach mud layer 1303 not mixed with sand to meet the requirements of certain intertidal zone organisms, but since the beach mud has poor water permeability, the area of pure beach mud in the main cylinder 1 cannot be too large, so as to avoid difficulty in water infiltration.

[0055] The bottom filter system 5 is arranged below the main cylinder 1, and the bottom filter system 5 includes a water inlet end and a water outlet end, and filter equipment and / or filter material are arranged along the direction from the water inlet end to the water outlet end, the filter equipment includes but is not limited to a protein separator, and the protein separator is generally placed at a position closest to the water inlet end of the bottom filter system 5, and the filter material can be live stone, which refers to stones salvaged from the sea bottom coral reef, and the stones are rich in bacterial flora and can improve water quality.

[0056] The water circulation system is used for connecting the bottom filter system 5 and the main cylinder 1, driving water to circulate in the main cylinder 1 and the bottom filter system 5, and the flow of the water circulation system is controllable, so as to form the tide rising and falling by controlling the flow, the water circulation system includes a water outlet pipe 6 and a water inlet device 7, the water outlet pipe 6 communicates the water circulation area 102 with the water inlet end of the bottom filter system 5, and the water inlet device 7 selectively communicates the water outlet end of the bottom filter system 5 with the water circulation area 102 and the tidal pool 2.

[0057] When the tide rises, the water supply device 7 of the water circulation system is in action, and the water supply device 7 simultaneously connects the water outlet end of the bottom filter system 5 with the water circulation area 102 and the tidal pool 2, as shown in Figure 2 and Figure 3 the water in the bottom filter system 5 is sent into the tidal pool 2, and when the tidal pool 2 is full of water, the water overflows from the upper edge of the tidal pool 2 to the land area 101, and because the tidal pool 2 buffers the impact force of the water flow, the sand and mud of the land area 101 are not subjected to strong impact, so that the sand and mud can be kept in place, forming a stable mudflat environment, and the water flowing into the land area 101 slowly penetrates downward through the laid object 13, at this time, the water supply speed is greater than the water penetration speed, so that the water level of the land area 101 in the main cylinder 1 rises until the water level of the land area 101 in the main cylinder 1 reaches the high tide level, at this time, because the water level in the main cylinder 1 is at the high tide level, the water penetration speed increases, the water supply device 7 lift increases, and the water supply speed decreases, so that the water supply speed is equal to the water penetration speed, and the water level in the main cylinder 1 is stabilized at the high tide level, when the tide needs to be receded, the flow of the water supply device 7 is reduced, and the water supply device 7 only connects the water outlet end of the bottom filter system 5 with the water circulation area 102, the main cylinder 1 stops water supply, but the water penetration is kept, and the water level starts to drop from the high tide level, as shown in Figures 4 to 6 ultimately exposing the land area 101 to achieve a complete ebb tide state, but at this time, the laid object 13 can still maintain a semi-moist to moist state, and there is still water in the tidal pool 2, so that the needs of the crabs, mudskippers and other organisms in the intertidal zone can be met.

[0058] Compared with the prior art, the water-land tidal cylinder provided by the embodiment of the utility model can adjust the size of the tidal pool 2 according to the size of the main cylinder 1 and the type of the bred organisms, as shown in Figure 7 , as shown in Figure 7 , compared with the tidal pool 2 in the embodiment shown in Figures 1 to 6 , the tidal pool 2' in the embodiment increases the depth, so that the water level in the tidal pool 2' during the ebb tide can be increased to breed fish in the seaside tidal pool, Figures 1 to 7 , the tidal pool 2 and the tidal pool 2' are in a split structure with the main cylinder 1, and the tidal pool 2 or the tidal pool 2' can be replaced according to the needs, in another embodiment, as shown in Figure 8 , the tidal pool 2'' is integrated with the main cylinder 1, and the tidal pool 2'' is surrounded by a partition plate arranged in the main cylinder 1, by changing the size and depth of the tidal pool 2, the tidal pool 2' or the tidal pool 2'', the area of the tidal pool 2 can be as small as possible while meeting the breeding requirements, the area of the land area 101 is increased, mainly to meet the needs of the organisms in the intertidal zone, such as various crabs, mudskippers and other organisms, and by increasing the depth of the tidal pool 2, the needs of a small amount of fish breeding in the seaside tidal pool, such as gobies and other fish, can be met, and the water-land tidal cylinder in the scheme has a simple structure, a low complexity and is convenient for miniaturization.

[0059] The water supply device 7 may include one or more water pumps. In this embodiment, the water supply device 7 adopts a dual-pump structure, such as... Figures 1 to 14 As shown, the water supply device 7 includes a first water pump 701 and a second water pump 703. The first water pump 701 is located at the outlet of the bottom filtration system 5 and is connected to the water circulation zone 102 via a first water supply pipe 702. During operation, the first water pump 701 remains running, maintaining constant water circulation between the water circulation zone 102 and the bottom filtration system 5, ensuring the water is always filtered, preventing the nitrification system from collapsing, and guaranteeing water quality. The second water pump 703 is connected to the tidal pool 2 via a second water supply pipe 704. The opening and closing of the second water pump 703 is controlled by a timer switch. When the timer switch is on, the main tank 1 begins to rise and maintains a high tide level; when the timer switch is off, the main tank 1 begins to recede and reaches a completely receded state. The second water supply pipe 704 can directly pass upwards through the bottom of the main tank 1 and the overhead filter isolation layer 3 to connect to the tidal pool 2. Figures 1 to 9 As shown, in this case, a sealing structure 4 needs to be installed between the overhead filter isolation layer 3 and the second water inlet pipe 704, as well as between the main cylinder 1 and the second water inlet pipe 704. Alternatively, the second water inlet pipe 704 can be inserted into the main cylinder 1 and connected to the tide pool 2 by opening a hole in the cylinder wall of the main cylinder 1, without passing through the bottom of the main cylinder 1. Figure 10 As shown, this method avoids passing through the bottom of the main cylinder 1 and the overhead filter isolation layer 3, thus avoiding the risk of leakage.

[0060] It should be noted that the second water supply pipe 704 can be directly connected to the bottom of the tidal pool 2, or it can extend upward through the bottom of the tidal pool 2. Alternatively, it can extend upward from one side of the tidal pool 2 to the top of the tidal pool 2 and connect to the downward-bending elbow 707 to connect the outlet of the second water supply pipe 704 to the tidal pool 2. Considering that organisms may bring mud and sand from the paving material 13 into the tidal pool 2, the preferred approach in this case is to use the second water supply pipe 704 extending upward from one side of the tidal pool 2 to the top of the tidal pool 2 and connecting to the downward-bending elbow 707 to connect the outlet of the second water supply pipe 704 to the tidal pool 2.

[0061] To further optimize the above technical solution, the flow rate in the second water supply pipe 704 can be achieved by adjusting the power of the second water pump 703, or by using a bypass pipeline, for example... Figures 1 to 13In the shown embodiment, the land tidal tank further comprises a circulating water pipe 8, the second upper water pipe 704 and the lower water pipe 6 are communicated through the circulating water pipe 8, the circulating water pipe 8 can be arranged outside the main tank 1 or arranged inside the main tank 1 and located in the water circulation area 102, in the present case, the circulating water pipe 8 is preferably arranged outside the main tank 1, the circulating water pipe 8 is provided with a first regulating valve 9, the opening of the first regulating valve 9 is adjustable, the first regulating valve 9 can be used to increase the flow in the second upper water pipe 704 or control the water level of the high tide level.

[0062] As a preferred, to avoid the second water pump 703 being closed during the ebb tide, resulting in the second upper water pipe 704 generating siphon effect on the water in the tidal pool 2, in an embodiment of the present application, as shown in Figures 1 to 9 , a check valve 705 is arranged upstream of the communication between the second upper water pipe 704 and the circulating water pipe 8, and / or, as shown in Figure 9 , the second upper water pipe 704 extends upward to a bend 707 connected downward, so that the outlet of the second upper water pipe 704 is downward to the tidal pool 2, and the bend 707 is provided with an anti-siphon hole 708.

[0063] When only the check valve 705 is arranged, as shown in Figure 2 and Figure 3 , the water pumped out by the second water pump 703 flows to the tidal pool 2 and the lower water pipe 6 through the second upper water pipe 704 and the circulating water pipe 8 respectively, because the water inflow is greater than the water outflow at this time, the water level in the tidal pool 2 increases and overflows to the land area 101, forming the rising tide, when the ebb tide, as shown in Figures 4 to 6 , the second water pump 703 is closed, the second upper water pipe 704 generates siphon effect on the water in the tidal pool 2, but due to the check valve 705, the siphoned water can only enter the lower water pipe 6 through the circulating water pipe 8, and then enter the inlet pipe of the bottom filter system 5, but cannot directly enter the second water pump 703, which plays a protective effect on the second water pump 703, and the siphon of the second upper water pipe 704 can speed up the ebb tide.

[0064] If the anti-siphon hole 708 is arranged at the bend 707, the second upper water pipe 704 cannot generate siphon effect on the water in the tidal pool 2 during the ebb tide, and can only rely on the downward extension of the laid layer to form drainage, compared with the case of only arranging the check valve 705, the ebb tide speed is relatively slow.

[0065] As shown in Figures 1 to 14 , in an embodiment of the present application, the overhead filter isolation layer 3 comprises a filter layer and a bottom filter frame 302, wherein the filter layer blocks sand and allows water flow, the bottom filter frame 302 is arranged below the filter layer, the bottom filter frame 302 and the bottom surface of the main tank 1 form a water circulation area 102, the filter layer includes but is not limited to nano bricks 301 and filter screens 304, and can also be composed of nano bricks 301 and filter screens 304.

[0066] As shown in Figure 11 , at least part of the lower side of the nano brick 301 is provided with a nano brick protrusion 303, which protrudes towards the water circulation area 102. Water in the water circulation area 102 can seep upwards into the land area 101 through the nano brick protrusion 303 and the nano brick 301, and can protrude to a height of half or more of the water circulation area 102. When the land area 101 is at low tide, water in the water circulation area 102 can seep upwards into the paving 13 through the nano brick protrusion 303 and the nano brick 301 to maintain the humidity of the paving 13.

[0067] Further optimization of the above technical solutions, as shown in Figures 1 to 14 , in the embodiment of the present application, the sewer pipe 6 is provided with a second regulating valve 10, which is used to adjust the water level of the water circulation area 102. The regulating valve is used to adjust the water level in the water flow space. When the opening degree of the second regulating valve 10 is increased, the water level in the water circulation area 102 decreases, and the nano brick protrusion 303 cannot contact the water surface, and the water seepage is stopped. When the opening degree of the second regulating valve 10 is reduced, the water level in the water circulation area 102 rises, and the nano brick protrusion 303 can contact the water surface, and the water seepage will be upwards. Therefore, by adjusting the second regulating valve 10, the water seepage and the non-water seepage can be controlled. The second regulating valve 10 can also reduce the noise of the sewer pipe 6.

[0068] In order to avoid the impact of the first upper water pipe 702 on the overhead filter isolation layer 3, as shown in Figures 1 to 14 , the water outlet of the first upper water pipe 702 located in the water circulation area 102 is provided with a branch pipe 706 for changing the water outlet direction to prevent water flow from impacting the filter layer. The branch pipe 706 of the water outlet of the first upper water pipe 702 can also be in the horizontal direction, or downward relative to the horizontal direction. As shown in Figures 1 to 14 , the water outlet of the first upper water pipe 702 is connected to the middle part of the branch pipe 706, and both ends of the length direction of the branch pipe 706 can drain water.

[0069] The water-land tidal tank also includes a spraying device 11, which includes at least one nozzle 1102 and a spraying pipe 1101 connected to the nozzle 1102. The water inlet of the spraying pipe 1101 is communicated with the fresh water source, and is used to clean the inner wall of the main tank 1.

[0070] In the embodiment in which the spraying device 11 has one nozzle 1102, the nozzle 1102 is arranged above the middle position of the main tank 1 and close to the tidal pool 2, which can simultaneously wash the inner wall of the main tank 1 and the pool wall of the tidal pool 2.

[0071] In the embodiment in which the spraying device 11 has at least two nozzles 1102, part of the nozzles 1102 are located above the land area 101, and part of the nozzles 1102 are located above or close to the tidal pool 2.

[0072] Freshwater can come from a storage container, pumped by a pump; ideally, the storage container should contain purified water. Alternatively, it can come from a tap water pipe equipped with a water purification system, controlled by a solenoid valve. The nozzle 1102 is a wide-angle type to spray water horizontally in all directions during spraying. When the water level in the main tank 1 drops to low tide, the spray device 11 is activated to flush seawater adhering to the tank walls into the water, preventing salt stains from evaporating. Spraying should be done after the water level in the water zone drops to low tide and before the seawater adhering to the tank walls evaporates; this timing is controlled by a timer switch. The main function of the spray device 11 is to keep the inner wall of the main tank 1 clean, which is beneficial for its aesthetic appeal.

[0073] like Figures 1 to 14 As shown in the embodiment of this application, the bottom filtration system 5 includes a bottom filter tank 501. The volume of the bottom filter tank 501 can be smaller than that of the main tank 1, or the same as that of the main tank 1, or larger than that of the main tank 1. Since this application is mainly used for raising intertidal organisms or fish in coastal tidal ponds, the requirements for water quality are relatively low. Therefore, the size of the bottom filter tank 501 can be appropriately reduced. The first end of the bottom filter tank 501 is the water inlet of the bottom filtration system 5, and the second end is the water outlet of the bottom filtration system 5.

[0074] To prevent small amounts of sediment or biological waste carried in the water from directly entering the bottom filtration system 5 and affecting water quality, in one embodiment of this application, the bottom filtration system 5 further includes a filter bag disposed at the first end of the bottom filter tank 501. The filter bag is connected to the outlet of the drain pipe 6. This not only filters out small amounts of sediment or biological waste carried in the water, preventing them from directly entering the bottom filtration system 5, but also reduces the sound of water flowing down the drain pipe 6. Alternatively, the bottom filtration system 5 also includes a filter device 502 disposed above the first end of the bottom filter tank 501. The filter device 502 is mainly used for physical filtration, intercepting impurities before they enter the bottom filtration system 5. The filter device 502 is located between the outlet of the drain pipe 6 and the bottom filter tank 501. That is, only a filter bag, only a filter device, or both a filter bag and a filter device 502 can be disposed at the outlet of the drain pipe 6. In this embodiment, a filter device 502 is used. The filter device 502 includes, but is not limited to, a dry-wet separation filter box and a roll paper filter.

[0075] To improve the filtration effect, in the embodiments of this application, such as Figures 1 to 12As shown, the bottom filter cylinder 501 is provided with a plurality of partition plate sets 12, and the internal region of the bottom filter cylinder 501 is divided into a plurality of functional compartments by the partition plate sets 12. The filter materials or filter devices can be placed in the functional compartments according to the needs. When the partition plate sets 12 are arranged, the size of the protein separator should be considered to avoid that the protein separator cannot be placed in the bottom filter cylinder 501. The water entering the bottom filter cylinder 501 flows through each functional compartment in turn. The arrangement direction of each partition plate set 12 can be determined according to the shape of the bottom filter cylinder 501 to maximize the use of the space of the bottom filter cylinder 501. For example, when the bottom filter cylinder 501 is rectangular, each partition plate set 12 is arranged along the length direction of the bottom filter cylinder 501 in turn. When the bottom filter cylinder 501 is square, if each partition plate set 12 is also arranged along the length direction of the bottom filter cylinder 501 in turn, each functional compartment in the bottom filter cylinder 501 will be too narrow or cannot be divided into more functional compartments. Therefore, in this case, each partition plate set 12 can be arranged in a cross shape or a T shape to maximize the use of the space of the bottom filter cylinder 501.

[0076] Specifically, as shown in the embodiment, Figures 1 to 12 The partition plate set 12 includes a flow baffle 1201 and an overflow plate 1202 arranged in parallel and side by side. The bottom of the flow baffle 1201 and the bottom surface of the bottom filter cylinder 501 form a first water flow channel. The overflow plate 1202 is connected with the bottom surface and the two side surfaces of the bottom filter cylinder 501, and the upper edge of the overflow plate 1202 is lower than the upper edge of the flow baffle 1201 and the bottom filter cylinder 501. The flow baffle 1201 and the overflow plate 1202 form a second water flow channel. The water in the upstream functional compartment flows into the downstream functional compartment through the first water flow channel, the second water flow channel and the space above the overflow plate 1202 in turn. Along the water flow direction, the height of the overflow plate 1202 in each partition plate set 12 decreases in turn.

[0077] The flow baffle 1201 can guide the water flow so that the water can flow through each functional compartment. The overflow plate 1202 can make the water in one functional compartment overflow into the next functional compartment. If the water level of the bottom filter cylinder 501 exceeds the height of the flow baffle 1201, the water will flow directly over the flow baffle 1201, which will affect the filtering effect of the bottom filter cylinder 501. Therefore, the height of the flow baffle 1201 determines the maximum water level of the bottom filter cylinder 501. The overflow plate 1202 can limit the minimum water level of the functional compartment in front of it. Since the second functional compartment of the bottom filter cylinder 501 along the water flow direction is usually an egg compartment (for placing the protein separator), the egg compartment needs to maintain a stable water level. When the main tank 1 is in the rising tide, the water volume of the bottom filter cylinder 501 decreases, and when the main tank 1 is in the ebb tide, the water volume of the bottom filter cylinder 501 increases. In order to keep the water level of the egg compartment stable when the water volume changes, the overflow plate 1202 between the first two compartments, i.e. the overflow plates 1202 upstream and downstream of the egg compartment, need to be appropriately raised, but the overflow plate 1202 is still lower than the flow baffle 1201, and the overflow plate 1202 after that is appropriately lowered. In this way, the water volume change of the bottom filter cylinder 501 is concentrated in the functional compartment 205 after the egg compartment. The heights of the two overflow plates 1202 upstream and downstream of the egg compartment can be equal, or the height of the overflow plate 1202 upstream of the egg compartment can be 0-3 cm higher than the height of the overflow plate 1202 downstream of the egg compartment.

[0078] It should be noted that when the water volume is small, the biomass is small, and the filtering demand is low, the bottom filter cylinder 501 can not be provided with the above-mentioned compartment plate group 12, as shown in Figure 13

[0079] Further optimization of the above technical solution can also adopt a scheme without a circulating water pipe 8 to achieve the control of rising and ebbing tides, as shown in Figure 14 The second water pump 703 is directly connected to the tide pool 2 through the second water inlet pipe 704, and there is no connection between the second water inlet pipe 704 and the water outlet pipe 6. In this case, the second water pump 703 is preferably a variable frequency water pump, which can achieve rising tide and ebbing tide by adjusting the frequency of the water pump. Of course, in this case, an anti-siphon hole 708 should be opened on the elbow 707 connected by the second water inlet pipe 704 to prevent siphon.

[0080] Of course, the water inlet device 7 can also adopt a single-pump structure to achieve rising tide and ebbing tide by one water pump. For example, the water pump can be connected to the tide pool 2 and the water outlet pipe 6 through a two-position three-way reversing valve. When the two-position three-way reversing valve is switched to connect the water pump to the tide pool 2, the rising tide process is performed, and the speed and water level of the rising tide can be controlled by controlling the frequency of the water pump. When the two-position three-way reversing valve is switched to connect the water pump to the water outlet pipe 6, the ebbing tide process is performed.
