[0002] The water and land tidal tank comprises a water area and a land area, when the tide rises, the water level of the water area rises, then the water of the water area will overflow to the land area through the overflow communication pipe between the water area and the land area, so that the water level of the land area also rises, according to the operation requirement of the water and land tidal tank, the water level of the land area only needs to submerge the land surface, and it is not necessary to rise too high, if the water level is too high, there will be more salted residues on the inner wall of the land area when the tide recedes, which affects the appearance, therefore, it is necessary to limit the water level of the land area when the tide rises.

[0003] At present, the water level of the land area is limited by adjusting the flow area of the overflow communication pipe between the water area and the land area, even if the water flow speed of the overflow communication pipe and the water infiltration speed of the land area reach balance, but the water infiltration speed of the land area will be affected by various factors such as the biological activity in the tank, and it often changes, which makes the water level of the land area unstable when the tide is high, and it is often too high or too low, therefore, how to ensure that the water level of the land area is stable when the tide is high becomes an important problem to be solved by the technical personnel in the field.

At this time, a section of air is stored in the overflow communication pipe, and the air mainly locates at the water outlet end of the overflow communication pipe extending to the bottom of the tidal pool in the early stage of the rising tide, and has smaller hindering effect on the water flow in the overflow communication pipe. However, as the water level of the land area gradually exceeds the water level of the tidal pool, and then rises together with the water level of the tidal pool, the water level in the overflow communication pipe also rises, which makes the air in the overflow communication pipe gradually move to the water inlet end of the overflow communication pipe, and the hindering effect of the air on the water flow in the overflow communication pipe increases, and the water flow speed in the overflow communication pipe slows down, and finally reaches the balance with the water infiltration speed of the land area, and the water level of the land area no longer rises, and is stable at the preset high tide level.

[0027] Therefore, the water-land tidal tank provided by the application can no longer rely on the control of the flow area of the overflow communication pipe to control the high tide water level of the land area, but uses the design of the positions of the water inlet end and the water outlet end of the overflow communication pipe to control the high tide water level of the land area, so as to ensure that the water level of the land area is stable at the high tide level.

DETAILED DESCRIPTION

[0036] Therefore, the core of the present application is to design a water-land tidal cylinder, which is structurally designed to ensure that the water level of the land area remains stable at high tide.

[0037] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 1 provide a schematic view of the water-land tidal cylinder when the cylinder is empty. The present application discloses a water-land tidal cylinder, which comprises a main cylinder 1, an overflow communication pipe 2, a bottom filtration system 3, and a water circulation system.

[0039] The separation plate 103 is arranged in the main cylinder 1, and the separation plate 103 divides the main cylinder 1 into at least one water area 101 and at least one land area 102. The water area 101 is used to contain configured seawater, and the land area 102 is used to form land for intertidal zone organisms to live. The separation plate 103 is made of a material that can withstand a certain pressure and is corrosion-resistant, such as a glass plate, an acrylic plate, etc.

[0040] The partition plate 103 can adopt various structures. For example, the partition plate 103 can be in a character-shaped structure, that is, the partition plate 103 can be connected with the bottom wall and the two opposite side walls of the main tank 1 to separate the area in the main tank 1. The partition plate 103 can also be in an L-shaped structure, that is, the partition plate 103 can be connected with the bottom wall and the two adjacent side walls of the main tank 1. The partition plate 103 can also be in a U-shaped structure, that is, the two end portions of the partition plate 103 are connected with one side wall and the bottom wall of the main tank 1. The partition plate 103 can also be in a T-shaped structure, that is, the two end portions of the partition plate 103 are connected with the two opposite side walls of the main tank 1, and the other end portion is connected with the other side wall. The bottom of the partition plate 103 is connected with the bottom of the main tank 1. The partition plate 103 can also be in a polygonal circumferentially closed structure, and only the bottom edge of the partition plate 103 is connected with the bottom wall of the main tank 1.

[0041] One or more partition plates 103 can be arranged in the main tank 1. When only one partition plate 103 is arranged in the main tank 1, the main tank 1 is divided into one land area 102 and one water area 101. When multiple partition plates 103 are arranged in the main tank 1, the main tank 1 can be divided into multiple land areas 102 and one water area 101, or multiple water areas 101 and one land area 102, which is not limited herein. Figure 1 The illustrated embodiment is a scheme in which one character-shaped partition plate 103 is arranged in the main tank 1, and the character-shaped partition plate 103 divides the main tank 1 into one land area 102 and one water area 101.

[0042] The height of the partition plate 103 is lower than the height of the side wall of the main tank 1. According to the land composition of the land area 102, the height of the partition plate 103 can be higher than the high tide level or lower than the high tide level. For example, when the land is sand, the sand is not easy to be carried up by the slow tidal flow, so the height of the partition plate 103 can be lower than the high tide level. In this way, after the tide rises, the organisms in the water area 101 can enter the land area 102, increasing the ornamental value. If the land is mudflat mud, the mudflat mud is easy to be carried into the water area 101 during the rising and falling tides, polluting the water quality. In this case, the height of the partition plate 103 should be higher than the high tide level to prevent the water area 101 from being directly connected with the land area 102 through the space above the partition plate 103.

[0043] The land area 102 is provided with a tidal pool 104 and an overhead filter isolation layer 105. The space above the overhead filter isolation layer 105 is used to form land that is isolated from the tidal pool 104. The land is composed of sand, a mixture of mudflat mud and sand, pure mudflat mud, etc. The land is generally formed by the user himself. The present water-land tidal tank is mainly used for breeding intertidal zone organisms, and a land with sufficient thickness is needed to meet the digging and hiding habits of the organisms, and to ensure that the water speed meets the requirements of the rising and falling tides.

[0044] The beach or mudflat surface of the land area 102 contains organic matter (algae, nematodes, organic debris, etc.) that can be eaten by intertidal zone organisms. The algae and nematodes therein come from growth and proliferation under suitable light, sand or mudflat mud, suitable salinity, humidity, etc.; the organic debris mainly comes from plankton and its debris, feed debris, fecal particles of aquatic organisms in the water area 101, and is carried to the land area 102 by the water flow during the rising tide of the water area 101, and then remains on the land surface. The light can come from natural sunlight or artificial light suitable for the growth of ordinary plants.

[0045] As shown in Figure 2 , in order to avoid the land being washed up to the tide pool 104 or the water area 101 during the rising and falling tides, the land is provided with a double-layer structure, that is, a sand layer with strong water permeability is first laid on the top of the overhead filtration isolation layer 105, and a mudflat mud layer or a mixed mud-sand layer made of mudflat mud and sand is laid on the sand layer. The mudflat mud has a certain viscosity and will only be washed away when the water flow is large. Since the rising and falling tides in the tank are relatively slow, the mudflat mud in the tank can basically remain in place, forming a stable mudflat environment.

[0046] The land in the land area 102 can be slightly lower than the tide pool 104 or the same height as the tide pool 104, as shown in the embodiment Figure 1 , the land is slightly lower than the tide pool 104.

[0047] The water circulation area 106 is formed overhead below the overhead filtration isolation layer 105. The water circulation area 106 is used to maintain filtration circulation between the main tank 1 and the bottom filtration system 3 during the rising and falling tides, to avoid the collapse of the nitrification system, and to plant plants such as mangroves in the land of the land area 102 to assist the bottom filtration system 3 in absorbing harmful substances in the tank.

[0048] The overflow communication pipe 2 is provided on the partition plate 103, and the water area 101 and the land area 102 can be connected through one or more overflow communication pipes 2. The water inlet end of the overflow communication pipe 2 extends into the water area 101 and is higher than the low tide level of the water area 101 and lower than the high tide level of the water area 101. The water outlet end of the overflow communication pipe 2 extends into the tide pool 104 and extends to the bottom of the tide pool 104 below the highest liquid level of the tide pool 104.

[0049] The bottom filtration system 3 is arranged below the main tank 1. The bottom filtration system 3 includes a water inlet end and a water outlet end. The water circulation system is used to connect the bottom filtration system 3 and the main tank 1. The water circulation system includes a water outlet pipe 4 and a water inlet device 5. The water outlet pipe 4 respectively communicates the water inlet end of the bottom filtration system 3 with the water circulation area 106 and the water outlet end of the water area 101. The water inlet device 5 selectively communicates the water outlet end of the bottom filtration system 3 with the water circulation area 106 and the water area 101. The bottom filtration system 3 and the water circulation system cooperate to filter and remove harmful substances in the water during water circulation.

[0050] When the tide rises in water zone 101 of the aforementioned tidal tank, as... Figure 3 As shown, the water level in water zone 101 gradually rises from the low tide level, exceeding the inlet end of the overflow connecting pipe 2. At this time, the water in water zone 101 will flow into the tide pool 104 through the overflow connecting pipe 2 and then overflow onto the land surface of land zone 102. At this time, a section of air is sealed inside the overflow connecting pipe 2. In the early stage of high tide, this section of air is mainly located at the outlet end of the overflow connecting pipe 2 extending to the bottom of the tide pool 104, and has a relatively small obstruction effect on the water flow inside the overflow connecting pipe 2.

[0051] However, as the water level in land area 102 rises, it gradually surpasses the water level in tidal pool 104, and then rises together with it. The water level in overflow pipe 2 also rises accordingly. This causes the air in overflow pipe 2 to gradually move towards the inlet end, increasing the obstruction to the water flow. The water flow velocity in overflow pipe 2 slows down, eventually reaching equilibrium with the rate of infiltration into land area 102. The water level in land area 102 then stops rising and stabilizes at the preset high tide level. Figure 4 As shown.

[0052] Therefore, the tidal tank provided in this application embodiment no longer relies on controlling the flow cross-sectional area of ​​the overflow connecting pipe 2 to control the high tide level of the land area 102. Instead, it uses the design of the positions of the inlet and outlet of the overflow connecting pipe 2 to control the high tide level of the land area 102, thereby ensuring that the water level of the land area 102 remains stable at high tide.

[0053] An overflow component is provided in the water area 101. A fish comb structure 109 is provided on the upper and / or lower part of the overflow component to prevent organisms in the water area 101 from falling into the overflow area 107. At the same time, the fish comb structure 109 can also easily remove the oil film formed on the surface of the water in the water area 101 due to feeding, excrement, etc. The overflow component forms an overflow area 107 in the water area 101, which is connected to the water area 101 through the fish comb structure 109. The overflow area 107 serves as the drainage end of the water area 101 and is connected to the drain pipe 4. That is, the water in the water area 101 first falls into the overflow area 107 through the fish comb structure 109 on the overflow component, and then enters the bottom filtration system 3 through the drain pipe 4 connected to the overflow area 107.

[0054] The fish comb structure 109 includes a plurality of elongated strip-shaped holes arranged in a horizontal direction to allow water to flow through while preventing organisms from entering the overflow area 107.

[0055] The low tide level of water zone 101 is determined by the overflow height of the overflow component. As long as the overflow height of the overflow component is high, the low tide level of water zone 101 will also be high. Therefore, water zone 101 can still have a high water level at low tide to meet the water needs of aquatic organisms.

[0056] On the other hand, the water inside the land area 102 can be discharged to the bottom filtration system 3 through the water circulation system, allowing the land inside the land area 102 to be fully exposed, forming a relatively deep and well-aerated land to meet the needs of intertidal organisms for land. The rise and fall of the water area 101 only requires a few centimeters, but the thickness of the land in the land area 102 can reach tens of centimeters, which can meet the needs of most intertidal burrowing organisms.

[0057] like Figure 1 As shown, in one embodiment of this application, the drain pipe 4 includes a first drain pipe 401, a second drain pipe 402, and a third drain pipe 403. The inlet ends of the first drain pipe 401 and the second drain pipe 402 extend into the overflow area 107, and the inlet end of the first drain pipe 401 is higher than the inlet end of the second drain pipe 402. The inlet end of the second drain pipe 402 is not higher than the overflow height of the overflow component, so that when the water level of the water area 101 is at a low tide level, the water entering the overflow area 107 is discharged through the second drain pipe 402. The height of the inlet end of the first drain pipe 401 is not higher than the high tide level, so that when the water level of the water area 101 is at a high tide level, the water entering the overflow area 107 is discharged together through the second drain pipe 402 and the first drain pipe 401.

[0058] The inlet of the third drain pipe 403 is connected to the water circulation zone 106 to allow water in the water circulation zone 106 to flow into the bottom filtration system 3. The outlets of the first drain pipe 401, the second drain pipe 402, and the third drain pipe 403 are connected in parallel to the inlet of the bottom filtration system 3.

[0059] An electric ball valve 404 is installed on the second drain pipe 402. When the water zone 101 in the tidal tank begins to recede from high tide, the electric ball valve 404 opens, and water begins to flow from both the first drain pipe 401 and the second drain pipe 402 simultaneously. When the water level is lower than the inlet of the first drain pipe 401, water mainly flows from the second drain pipe 402, and the water zone 101 begins to recede, causing the water level in the zone to decrease. This continues until the inflow and outflow rates are equal, at which point the water level in the zone 101 stops changing.

[0060] The electric ball valve 404 is controlled by a timing switch, which can be a normally open electric ball valve 404: open when power off, close when power on; or a normally closed electric ball valve 404: open when power on, close when power off. The difference between the two in use lies in the different setting methods of the timing switch: if the normally open electric ball valve 404 is used, the timing switch is powered on during high tide and powered off during low tide; if the normally closed electric ball valve 404 is used, the opposite is true. The following describes the normally open electric ball valve 404 as an example.

[0061] The initial stage of high tide in the water area 101: as shown in FIG. 1, the normally open electric ball valve 404 is in an open state, and the water area 101 is maintained at a low tide level. When the timing switch is powered on, the electric ball valve 404 is closed, as shown in FIG. 2, at this time the water level in the water area 101 is at a low tide level, and cannot be drained through the first drain pipe 401 and the second drain pipe 402, so the water area 101 stops draining, but the water area 101 still rises in water level, and the bottom cylinder water level drops, until the water level in the water area 101 rises to the high tide level, and the first drain pipe 401 starts to drain, and the water level in the water area 101 no longer rises. Figure 2 Figure 3 The initial stage of low tide in the water area 101: as shown in FIG. 3, when the timing switch is powered off, the electric ball valve 404 is opened, and the first drain pipe 401 and the second drain pipe 402 simultaneously drain, at this time the drain flow is greater than the inflow, and the water level in the water area 101 starts to drop, when the water level is lower than the water inlet end of the first drain pipe 401, only the second drain pipe 402 drains, the drain flow decreases, and the inflow and outflow remain balanced, and the water level in the water area 101 is at a low tide level.

[0062] The initial stage of low tide in the water area 101: as shown in FIG. 3, when the timing switch is powered off, the electric ball valve 404 is opened, and the first drain pipe 401 and the second drain pipe 402 simultaneously drain, at this time the drain flow is greater than the inflow, and the water level in the water area 101 starts to drop, when the water level is lower than the water inlet end of the first drain pipe 401, only the second drain pipe 402 drains, the drain flow decreases, and the inflow and outflow remain balanced, and the water level in the water area 101 is at a low tide level. Figure 4 The first drain pipe 401, the second drain pipe 402 and the third drain pipe 403 are connected in parallel and share a total outlet, which should be appropriately enlarged, so as to avoid mutual influence when the first drain pipe 401, the second drain pipe 402 and the third drain pipe 403 drain, and reduce the drain noise. A filter bag can be sleeved at the total outlet to filter the water about to enter the bottom filter system 3, or a rain pipe can be connected and a dry-wet separation box can be provided, and the rain pipe is inserted into the dry-wet separation box.

[0063] To facilitate the adjustment of the drain flow, in an embodiment of the present application, as shown in FIG. 4, a first adjusting valve 405 for adjusting the drain flow is arranged on each of the first drain pipe 401, the second drain pipe 402 and the third drain pipe 403, and the first adjusting valve 405 can be a manual valve or an electric valve, which is not limited herein. The first adjusting valve 405 on each drain pipe is adjusted to an appropriate range, so as to not only adjust the drain flow to match the inflow, but also reduce the drain noise of each drain pipe.

The first adjusting valve 405 on each drain pipe is adjusted to an appropriate range, so as to not only adjust the drain flow to match the inflow, but also reduce the drain noise of each drain pipe.​​

[0065] As Figure 1 shown in the embodiment of the present application, the overflow member is an overflow plate 3032, and a back-packing water tank 1072 is externally arranged on the cylinder wall opposite to the overflow plate 3032, the back-packing water tank 1072 can reduce the occupation of the internal space of the main cylinder 1, so that the overflow plate 3032 is close to the cylinder wall of the main cylinder 1, thereby reducing the visual obstruction in the main cylinder 1, the overflow plate 3032 and the cylinder wall of the main cylinder 1 where the back-packing water tank 1072 is arranged form an overflow gap 1071, the upper part of the cylinder wall of the main cylinder 1 where the back-packing is arranged is provided with a notch for communicating the overflow gap 1071 with the back-packing water tank 1072, and the overflow gap 1071 and the back-packing water tank 1072 jointly constitute an overflow area 107, and the first drain pipe 401 and the second drain pipe 402 are arranged in the back-packing water tank 1072.

[0066] As Figure 1 shown, the back-packing water tank 1072 is surrounded by a back-packing bottom plate and three back-packing side plates, the three back-packing side plates are sequentially connected and stand upward from the three sides of the back-packing bottom plate, and the back-packing bottom plate and the two back-packing side plates arranged oppositely are respectively connected to the outer surface of the cylinder wall of the main cylinder 1, and the first drain pipe 401 and the second drain pipe 402 pass through the back-packing bottom plate from the lower part of the back-packing bottom plate and extend into the back-packing water tank 1072.

[0067] Of course, it should be noted that the overflow member is not limited to the overflow plate 3032, and in other embodiments, the overflow member can also be an overflow sleeve, the first drain pipe 401 and the second drain pipe 402 are located in the overflow sleeve, and the second drain pipe 402 is sleeved outside the first drain pipe 401, and the second drain pipe 402 also needs to be provided with an electric ball valve 404, thereby forming a triple overflow pipe, and the upper end and / or the lower end of the overflow sleeve is provided with a fish comb structure 109.

[0068] Of course, only one total drain pipe can also be arranged in the overflow sleeve, and the total drain pipe is connected to the bottom filter system 3 through two branch drain pipes at the lower part outside the main cylinder 1, and an electric ball valve 404 is arranged on one of the two branch drain pipes, and this structure is called a double overflow pipe, and the diameter of the double overflow pipe is smaller than that of the triple overflow pipe, which helps to reduce the occupation of the internal space of the main cylinder 1 and helps to improve the ornamental value.

[0069] As Figure 1 and Figure 5 shown, in an embodiment of the present application, the overflow communication pipe 2 is provided with a second adjusting valve 6, and the second adjusting valve 6 is used to adjust the flow area of the overflow communication pipe 2, so as to adjust the flow in the overflow communication pipe 2.

[0070] From Figure 5As can be seen, the overflow communication pipe 2 in the case is composed of a horizontal pipe section and an elbow pipe section, the first end of the horizontal pipe section is located in the water area 101, the second end extends into the land area 102 through the partition plate 103, the second end of the horizontal pipe section is connected to the elbow pipe section, and the second regulating valve 6 is arranged on the horizontal pipe section.

[0071] Meanwhile, the part of the overflow communication pipe 2 extending to the bottom of the tidal pool 104 is located above the water surface of the tidal pool 104, and an exhaust hole 201 can be opened at this position, that is, the exhaust hole 201 is arranged on the elbow pipe section, so that during the rising tide, when the water level of the tidal pool 104 in the land area 102 begins to rise, the air in the overflow communication pipe 2 is discharged from the exhaust hole 201, and when the water level of the land area 102 exceeds the exhaust hole 201, the remaining air in the overflow communication pipe 2 is only then sealed in the pipe, thereby playing a role in limiting the water level. By changing the height of the exhaust hole 201, the water level height of the high tide level of the land area 102 can be adjusted, and it should be noted that the water level height of the high tide level of the land area 102 should be slightly higher than the height of the exhaust hole 201.

[0072] In order to prevent the organisms in the water area 101 from entering the overflow communication pipe 2, a fish screen 7 is arranged at one end of the overflow communication pipe 2 in the water area 101.

[0073] As shown in Figure 1 The bottom filter system 3 includes a bottom filter cylinder 301, the first end of the bottom filter cylinder 301 is the water inlet end of the bottom filter system 3, and the second end is the water outlet end of the bottom filter system 3. The volume of the bottom filter cylinder 301 can be smaller than, the same as, or larger than the main cylinder 1. Since the case is mainly used for breeding intertidal organisms or fish in the tidal pool 104, the water quality requirement is relatively low, and therefore the size of the bottom filter cylinder 301 can be appropriately reduced. The first end of the bottom filter cylinder 301 is the water inlet end of the bottom filter system 3, and the second end is the water outlet end of the bottom filter system 3.

[0074] To avoid the small amount of silt or biological excrement and other impurities carried in the water directly into the bottom filter system 3 and affect the water quality, in an embodiment of the present application, the bottom filter system 3 further comprises a filter bag arranged at the first end of the bottom filter cylinder 301, and the filter bag is connected to the water outlet end of the sewer pipeline 4. In this way, not only can the small amount of silt or biological excrement and other impurities carried in the water be filtered, so as to avoid the small amount of silt or biological excrement and other impurities carried in the water directly entering the bottom filter system 3, but also the sound of falling water in the sewer pipeline can be reduced, and / or the bottom filter system 3 further comprises a filter device 302 arranged above the first end of the bottom filter cylinder 301, and the filter device 302 is mainly used for physical filtration and intercepts impurities before they enter the bottom filter system 3. The filter device 302 is located between the water outlet end of the sewer pipeline 4 and the bottom filter cylinder 301, that is, the filter bag can be arranged only at the water outlet end of the sewer pipeline 4, or the filter device 302 can be arranged only at the water outlet end of the sewer pipeline 4, or the filter bag and the filter device 302 can be arranged simultaneously at the water outlet end of the sewer pipeline 4. In the embodiment of the present application, the filter device 302 is adopted. The filter device 302 includes but is not limited to a dry-wet separation filter box and a paper roll filter.

[0075] To improve the filtering effect, in an embodiment of the present application, as shown in Figure 1 The inside of the bottom filter cylinder 301 is divided into a plurality of functional compartments 304 by the grid plate group 303, and the functional compartments 304 can be placed with the above-mentioned filter materials or filter devices according to needs. When the grid plate group 303 is arranged, the size of the protein separator needs to be considered to avoid that the protein separator cannot be placed in the bottom filter cylinder 301. The water entering the bottom filter cylinder 301 flows through each functional compartment 304 in turn, and the arrangement direction of each grid plate group 303 can be determined according to the shape of the bottom filter cylinder 301 to maximize the use of the space of the bottom filter cylinder 301. For example, when the bottom filter cylinder 301 is rectangular, each grid plate group 303 is arranged in the length direction of the bottom filter cylinder 301 in turn. When the bottom filter cylinder 301 is square, if each grid plate group 303 is also arranged in the length direction of the bottom filter cylinder 301 in turn, each functional compartment 304 in the bottom filter cylinder 301 will be too narrow or cannot be divided into more functional compartments 304. Therefore, in this case, each grid plate group 303 can be arranged in a cross shape or a T shape to maximize the use of the space of the bottom filter cylinder 301.

[0076] Specifically, as shown in Figure 1In the shown embodiment, the baffle plate group 303 comprises parallel and side-by-side arranged flow baffles 3031 and overflow baffles 3032. The bottom of the flow baffles 3031 and the bottom surface of the bottom filter cylinder 301 form a first water flow channel. The overflow baffles 3032 are connected with the bottom surface and the two side surfaces of the bottom filter cylinder 301, and the upper edge of the overflow baffles 3032 is lower than the upper edge of the flow baffles 3031 and the bottom filter cylinder 301. The flow baffles 3031 and the overflow baffles 3032 form a second water flow channel. The water in the upstream functional compartment 304 flows into the downstream functional compartment 304 through the first water flow channel, the second water flow channel and the space above the overflow baffles 3032 in sequence. The height of the overflow baffles 3032 in each baffle plate group 303 decreases in sequence along the water flow direction.

[0077] The flow baffles 3031 can guide the water flow to flow through each functional compartment 304. The overflow baffles 3032 make the water in one functional compartment 304 overflow into the next functional compartment 304. If the water level of the bottom filter cylinder 301 exceeds the height of the flow baffles 3031, the water flow will directly pass above the flow baffles 3031, which will affect the filtering effect of the bottom filter cylinder 301. Therefore, the height of the flow baffles 3031 determines the maximum water level height of the bottom filter cylinder 301. The overflow baffles 3032 can limit the minimum water level of the functional compartment 304 in front of it. Since the second functional compartment 304 along the water flow direction of the bottom filter cylinder 301 is usually an egg compartment (for placing an egg protein separator), the egg compartment needs to maintain a stable water level. When the main cylinder 1 is in the rising tide, the water volume of the bottom filter cylinder 301 decreases, and when the main cylinder 1 is in the ebb tide, the water volume of the bottom filter cylinder 301 increases. In order to keep the water level of the egg compartment stable when the water volume changes, the overflow baffles 3032 between the first two compartments, i.e. the overflow baffles 3032 upstream and downstream of the egg compartment, need to be appropriately raised, but the overflow baffles 3032 are still lower than the flow baffles 3031, and the subsequent overflow baffles 3032 are appropriately lowered. In this way, the water volume change of the bottom filter cylinder 301 is concentrated in the functional compartments 304 after the egg compartment. The heights of the two overflow baffles 3032 upstream and downstream of the egg compartment can be equal, or the height of the overflow baffle 3032 upstream of the egg compartment is higher than the height of the overflow baffle 3032 downstream of the egg compartment by 0-3 cm.

[0078] It should be noted that when the water volume is small, the biomass is small, and the filtering demand is low, the baffle plate group 303 described above can not be arranged in the bottom filter cylinder 301.

[0079] The water supply device 5 includes a water pump 501, a first water supply pipe 502, and a second water supply pipe 503. The water pump 501 is installed inside the bottom filter cylinder 301. The water pump 501 is preferably a variable frequency water pump with adjustable flow rate and is located at the second end of the bottom filter cylinder 301. The outlet end of the water pump 501 is connected to the inlet ends of the first water supply pipe 502 and the second water supply pipe 503. The outlet end of the first water supply pipe 502 is connected to the water circulation zone 106, and the outlet end of the second water supply pipe 503 is connected to the water zone 101. The outlet end of the second water supply pipe 503 extends upward to a position near the upper edge of the main cylinder 1 and connects to a horizontal extension pipe 505 and / or a bent pipe 506. The horizontal extension pipe 505 or the bent pipe 506 is provided with an anti-siphon hole 507. The first water supply pipe 502 and the second water supply pipe 503 are respectively provided with a third regulating valve 508 for adjusting the water supply flow rate.

[0080] The outlet end of the first water supply pipe 502 is provided with a guide pipe 504. The guide pipe 504 is parallel to the bottom wall of the main cylinder 1, that is, the axis of the guide pipe 504 is parallel to or approximately parallel to the bottom wall of the main cylinder 1, so that the water outlet of the first water supply pipe 502 flows into the water circulation area 106 in a direction parallel or basically parallel to the bottom wall of the main cylinder 1, avoiding scouring the overhead filter isolation layer 105.

[0081] like Figure 1 As shown, in one embodiment of this application, the second water inlet pipe 503 passes through the bottom plate of the backpack water tank 1072 from bottom to top and extends upward.

[0082] like Figure 1 As shown in this application, the overhead filter isolation layer 105 includes a filter layer 1052 and a bottom filter frame 1051. The filter layer 1052 blocks sand and allows water to flow. The filter layer 1052 includes, but is not limited to, nano bricks and filter screens, and can also be composed of nano bricks and filter screens. The bottom filter frame 1051 is located below the filter layer 1052. The bottom filter frame 1051 is a grid frame with supporting legs. Its function is to support the filter layer 1052 and form a water circulation zone 106 below it to facilitate water infiltration from the land to the water circulation zone 106.

[0083] In this application, the filter layer 1052 is composed of nano-bricks, and at least a portion of the nano-bricks have nano-brick protrusions below them. These protrusions extend into the water circulation zone 106, allowing water in the water circulation zone 106 to seep upwards into the land area through the nano-brick protrusions and the nano-bricks. The protrusions can extend to half or more of the height of the water circulation zone 106. When the land area recedes, the water in the water circulation zone 106 can seep upwards into the land through the nano-brick protrusions and the nano-bricks to maintain the humidity of the land.

[0084] The gap between the filter layer 1052 and the cylinder wall of the main cylinder 1 is sealed by using foaming glue, landscaping mud, cement or other materials, or is sealed by using a sealing ring, a sealing strip or the like, so that sand does not fall into the water circulation area 106, and water flow does not enter the water circulation area 106 below without passing through the filter layer 1052.

[0085] Since intertidal zone organisms can enter the tide pool 104 or the water area 101 during the process of ebb and flow tides, in order to facilitate the intertidal zone organisms to enter and exit the tide pool 104 or the water area 101, in an embodiment of the present application, a protrusion, a rough coating or a grid plate 110 is arranged on the surface of the side of the partition plate 103 close to the water area 101, and a protrusion, a rough coating or a grid plate 110 is also arranged on the pool wall of the tide pool 104, so as to facilitate the intertidal zone organisms to climb.

[0086] Of course, in order to facilitate the intertidal zone organisms to climb, the partition plate 103 can also be inclined from the bottom to the land area 102, and the pool wall of the tide pool 104 can also be formed into an inclined slope, so as to facilitate the organisms to climb out of the tide pool 104 and return to the land area 102.

[0087] After the mud and sand of the tidal flat are laid, the tide pool 104 is directly placed below the water outlet of the overflow communication pipe 2. In order to improve the stability of the tide pool 104, the bottom of the tide pool 104 can be sunk into the land. In this way, the distance between the pool opening of the tide pool 104 and the upper surface of the land is also reduced, so as to further reduce the impact force of water flow on the land, and facilitate various organisms in the land area 102 to climb into the tide pool 104.

[0088] For some organisms in the water-land tide cylinder, such as springfish, the springfish frequently moves back and forth between the land area 102 and the water area 101. If the springfish directly enters the water area 101 from the land area 102, the mud and sand adhered to the springfish will be brought into the water area 101, thereby polluting the water area 101. Therefore, a sand washing water tank is designed in an embodiment of the present application, which is arranged on the top of the side of the partition plate 103 close to the land area 102. The organisms must pass through the sand washing water tank before entering the water area 101 from the land area 102. The water in the sand washing water tank can make the mud and sand on the organisms fall off, so that the water area 101 is not polluted after the organisms enter the water area 101. The mud and sand falling from the organisms will be deposited at the bottom of the sand washing water tank.
