Description

Technical Field

[0001] The invention relates to the field of fish tanks, in particular to an amphibious tidal tank. Background Art

[0002] In the prior art, the land layer and water in the tidal cylinder are located in the same area. When the water in the tidal cylinder rises, the water level rises, the land layer is submerged, and the internal air is discharged; when the water in the tidal cylinder recedes, the land layer emerges from the water, the internal water is discharged, and the air enters the land layer again. In order to maintain the good air permeability of the land layer and facilitate the growth of intertidal organisms, the land layer should be exposed to the water surface as much as possible during low tide, but in this case, the water level in the cylinder needs to drop to a very low position, which is not conducive to the growth of aquatic organisms. Therefore, how to ensure that the land layer can be fully exposed to the water surface when the tidal cylinder is at low tide, while ensuring that there is still a high water level in the tidal cylinder, so as to take into account the growth of intertidal organisms and aquatic organisms, is a key problem that needs to be solved by those skilled in the art.

DETAILED DESCRIPTION

[0060] In view of this, the core of the present invention is to design an amphibious tidal tank, which can ensure that the land layer is thick and has good air permeability when the amphibious tidal tank is at low tide, and at the same time ensure that the water level in the amphibious tidal tank is high, thereby facilitating the growth of intertidal organisms and aquatic organisms.

[0061] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0062] The present invention discloses a tidal tank, please refer to the attached Figure 1 , attached Figure 1 The schematic diagram of the structure of the tidal aquarium when the aquarium is empty is provided in a specific embodiment of the present invention. The tidal aquarium comprises a main aquarium 1 and a bottom aquarium 2, and in particular, further comprises a partition plate 103, an overflow device, a water discharge area 104, a first water discharge pipe 105, a second water discharge pipe 106, a third water discharge pipe 112, a first water supply pipe 107 and a water pump 204.

[0063] The partition plate 103 may be a glass plate, connected to the front and rear side plates and the bottom plate of the master cylinder 1, and no gap is left at the connection, so as to divide the master cylinder 1 into a land area 102 and a water area 101. The number of the partition plates 103 in the master cylinder 1 is at least one, such as Figure 1-Figure 13 As shown, the main cylinder 1 has a partition plate 103 in the embodiment, the main cylinder 1 is divided into a land area 102 and a water area 101; Fig.18As shown, there are two partition plates 103 in the master cylinder 1, which divide the master cylinder 1 into two land areas 102 and a water area 101, and the two land areas 102 are located on both sides of the water area 101. In the embodiment of the master cylinder 1 having two partition plates 103, the two land areas 102 and the one water area 101 can be arranged in a straight line, in an L shape, or in a T shape.

[0064] The water in the water area 101 can overflow into the land area 102 through the partition plate 103 , and the overflow height of the partition plate 103 is lower than the high tide level of the water area 101 and higher than the low tide level of the water area 101 .

[0065] The overflow device is used to make the water in the water area 101 overflow into the water area 104. Optionally, the height of the overflow device is flush with the low tide level. The first downcomer 105 and the second downcomer 106 are both arranged in the water area 104. The water inlet of the first downcomer 105 is higher than the water inlet of the second downcomer 106. The water inlet of the second downcomer 106 is not higher than the overflow height of the overflow device, so that when the water level of the water area 101 reaches the low tide level, the water entering the water area 104 is discharged through the second downcomer 106. The water inlet height of the first downcomer 105 is flush with the high tide level, so that when the water level of the water area 101 reaches the high tide level, the water entering the water area 104 is discharged through the second downcomer 106 and the first downcomer 105.

[0066] The water inlet of the third downpipe 112 is connected to the land area 102 for draining the water in the land area 102. The water outlets of the first downpipe 105, the second downpipe 106 and the third downpipe 112 are all connected to the bottom tank 2. The second downpipe 106 is provided with an electric ball valve 108.

[0067] The water pump 204 is disposed in the sump 2, and the water outlet of the water pump 204 is connected to the water inlet of the first water supply pipe 107, and the water outlet of the first water supply pipe 107 is connected to the water area 101. The water pump 204 delivers the water in the sump 2 to the water area 101 through the first water supply pipe 107.

[0068] If the water area 101 in the water and land tidal tank is at a high tide, then the electric ball valve 108 is opened, the second downpipe 106 starts to discharge water, the water area 101 starts to ebb, and the water level in the water area 101 starts to decrease. When the water level in the water area 101 is lower than the first downpipe 105, only the second downpipe 106 discharges water, and then the water volume of the first uppipe 107 and the water volume of the second downpipe 106 reach a balance, and the water area 101 is at a low tide.

[0069] The overflow height of the partition plate 103 is higher than the low tide level of the water area 101 and lower than the high tide level of the water area 101. When the water level of the water area 101 exceeds the overflow height of the partition plate 103, the water in the water area 101 will overflow into the land area 102 through the partition plate 103, and the land layer 117 in the land area 102 will be submerged. When the water area 101 is low tide, when the water level in the water area 101 is lower than the overflow height of the partition plate 103, the water in the water area 101 will no longer flow into the land area 102. Since the third downpipe 112 remains unobstructed, the water in the land area 102 will continue to enter the bottom tank 2 through the third downpipe 112. As long as there is enough time, the accumulated water in the land area 102 can be completely discharged, so that the entire land layer 117 can be exposed.

[0070] The height of the low tide level of the water area 101 is determined by the overflow height of the overflow device. As long as the overflow height of the overflow device is high, the height of the low tide level of the water area 101 is also high. Therefore, the water area 101 can still have a high water level at low tide to meet the water needs of aquatic organisms. On the other hand, the accumulated water inside the land area 102 can be discharged to the bottom cylinder 2 through the third downpipe 112, so the land layer 117 in the land area 102 can be fully exposed to form a relatively thick and well-permeable land layer 117 to meet the needs of intertidal zone organisms for the land layer 117. The amplitude of the rise and fall of the water area 101 only needs to be a few centimeters, but the thickness of the land layer 117 in the land area 102 can reach tens of centimeters, which can meet the needs of most intertidal zone cave dwelling organisms.

[0071] The water area 101 of the tidal tank of the present invention has a higher water level at low tide, and the land area 102 has a higher land layer 117, so that the demand of aquatic organisms for water volume and the demand of intertidal organisms for land layer 117 can be met, which is beneficial to the growth of intertidal organisms and aquatic organisms. In addition, the higher land layer 117 can provide intertidal burrowing organisms with deeper caves, which is beneficial to their survival and improves the ornamental value.

[0072] The electric ball valve 108 is controlled by a timer switch. It can be a normally open electric ball valve: open when the power is off and closed when the power is on; it can also be a normally closed electric ball valve: open when the power is on and closed when the power is off. The difference between the two in use lies in the different settings of the timer switch: if a normally open electric ball valve is used, the tide rises when the timer switch is powered on and the tide ebbs when the power is off; if a normally closed electric ball valve is used, the opposite is true. The following description takes the normally open electric ball valve 108 as an example.

[0073] Water Zone 101 Initial stage of high tide: Attached Figure 6 Schematic diagram of the structure of the water and land tidal cylinder when the water area 101 is at low tide. Figure 6The timing switch is in the off state, so the normally open electric ball valve 108 is in the open state, and the water area 101 is maintained at the low tide level. When the timing switch is powered on, the electric ball valve 108 is closed, and the water area 101 stops draining water, but the first water supply pipe 107 continues to supply water as usual, so the water level of the water area 101 rises and the water level of the bottom tank 2 drops. Figure 2 As shown, attached Figure 2 This is a schematic diagram of the structure of the water and land tidal tank at the initial stage of high tide.

[0074] Water Zone 101 High Tide Final Stage: Please refer to the attached Figure 3 , attached Figure 3 The schematic diagram of the structure of the water and land tidal cylinder at the final stage of the tide. As the tide rises in the water area 101, when the water level in the water area 101 is higher than the overflow height of the partition plate 103, the water in the water area 101 overflows into the land area 102, gradually submerging the surface of the land layer 117, and gradually seeping downward. Since the speed of water seepage is very slow, the water inflow speed of the land area 102 exceeds the water seepage speed, and the water level of the land area 102 gradually rises. After the water level in the land area 102 rises, the water seepage speed will also increase, and finally the water inflow speed and the water seepage speed of the land area 102 will reach a balance, and the water level of the land area 102 will be maintained at a certain height. On the other hand, in the water area 101, as the water level rises, after the water level exceeds the water inlet of the first down pipe 105, the water will be discharged through the first down pipe 105, and then the water volume of the first up pipe 107 and the water volume of the first down pipe 105 will gradually balance, and the water area 101 reaches the high tide level.

[0075] Initial stage of low tide in water area 101: When the timer switch is powered off, the electric ball valve 108 opens, and the second downpipe 106 is connected, so the downflow rate increases significantly, the water level in the main tank 1 water area 101 begins to drop, and the water level in the bottom tank 2 begins to rise. Please refer to the attached Figure 4 , attached Figure 4 This is a schematic diagram of the structure of the water and land tidal tank at the initial stage of low tide.

[0076] When the water level of the water area 101 drops below the overflow height of the partition plate 103, the water area 101 stops delivering water to the land area 102, and the water level of the land area 102 begins to drop. Since the water level of the land area 102 drops much slower than that of the water area 101, when the water level of the water area 101 drops to the low tide level, the water level of the land area 102 only drops a small part, but the water level of the land area 102 will continue to drop for a period of time, exposing the land layer 117, and finally the entire land layer 117 will be fully drained of the internal water. Please refer to the attached Figure 5 , attached Figure 5 This is a schematic diagram of the structure of the water and land tidal tank at the final stage of low tide.

[0077] As the water level in the water area 101 drops, the water level is lower than the water inlet of the first downpipe 105, and the first downpipe 105 stops draining water. After that, the amount of water discharged from the second downpipe 106 and the amount of water supplied from the first supply pipe 107 gradually reach a balance, and the water area 101 is maintained at a low tide level. Please refer to the attached figure. Figure 6 , attached Figure 6 It is a structural schematic diagram of the water and land tidal tank when the water area 101 is at low tide.

[0078] Please refer to the attached Figure 1 The first downpipe 105, the second downpipe 106 and the third downpipe 112 share a common water outlet, which should be appropriately enlarged to avoid the first downpipe 105, the second downpipe 106 and the third downpipe 112 from influencing each other when discharging water, thereby reducing the noise of water discharge. A filter bag can be placed at the total water outlet to filter the water that is about to enter the bottom tank 2.

[0079] The water inlet of the first downpipe 105 determines the water level of the water area 101 at high tide. The first downpipe 105 is provided with a regulating valve, and the noise of the downpipe can be reduced by adjusting the regulating valve to a proper range.

[0080] The second sewer pipe 106 is normally launched at low tide and during ebb tide in the water area 101 . A regulating valve is provided on the second sewer pipe 106 , and the regulating valve is used to reduce the noise of the second sewer pipe 106 .

[0081] The water pump 204 is preferably a variable frequency water pump with adjustable flow rate.

[0082] In a specific implementation of the present invention, the overflow of the water area 101 to the lower water area 104 is a backpack overflow. Figure 1 -Attached Figure 6 The backpack overflow is shown in the figure. The specific structure is as follows: a backpack is arranged on the outside of a main cylinder side plate 118 of the main cylinder 1. The backpack specifically includes a backpack side plate 109 and a backpack bottom plate 110. The backpack side plate 109 includes a first side plate opposite to the main cylinder side plate 118, a front side plate and a rear side plate located between the first side plate and the main cylinder side plate 118. The front side plate and the rear side plate are opposite to each other, and the front side plate, the rear side plate and the first side plate are arranged to form a U-shaped structure. The corresponding part of the main cylinder side plate 118 and the backpack side plate 109, the backpack side plate 109 and the backpack bottom plate 110 together form a water area 104. In this embodiment, the water area 104 is located outside the water area 101, so that the water area 101 can be ensured to have sufficient space.

[0083] As can be seen from the above description, the water in the water area 101 overflows to the lower water area 104 through the overflow device. In this embodiment, the overflow device specifically includes a fish intercepting comb 115 and a notch 1181 opened on the main cylinder side plate 118. The notch 1181 corresponds to and is connected to the upper end of the backpack. Fig. 20As shown, the main cylinder side plate 118 is only provided with a notch 1181 at the position corresponding to the backpack. After the notch 1181 is provided on the main cylinder side plate 118, the height of the position where the notch 1181 is provided on the main cylinder side plate 118 is lower than the height of the position where the notch 1181 is not provided on the main cylinder side plate 118. The fish intercepting comb 115 is provided on the inner side of the main cylinder side plate 118, and the fish intercepting comb 115 and the main cylinder side plate 118 enclose a first overflow channel. The lower part and the upper part of the fish intercepting comb 115 are respectively provided with a first fish intercepting hole, and the first fish intercepting hole connects the water area 101 and the first overflow channel. The first overflow channel is connected to the backpack, or the lower water area 104, through the space at the top of the main cylinder side plate 118.

[0084] When the second downpipe 106 is launched, the water flows as follows: the water in the water area 101 flows into the first overflow channel through the first fish blocking holes at the upper and lower parts of the fish blocking comb 115; the water in the first overflow channel overflows into the backpack through the top surface of the main cylinder side plate 118, and then flows into the bottom cylinder 2 through the second downpipe 106.

[0085] The first water pipe 107 can be located outside the backpack or inside the backpack. In the embodiment where the first water pipe 107 is located inside the backpack, the first water pipe 107 extends upward after passing through the backpack bottom plate 110, and finally leads to the water area 101. In order to save space, the first water pipe 107, the first down pipe 105 and the second down pipe 106 are arranged in parallel with the main cylinder side plate 118. In this specific embodiment, the backpack bottom plate 110 should be raised as much as possible to reduce the water capacity of the backpack area. When the water area 101 is at low tide, the amount of water in the backpack area is very small, and at high tide, the water level in the backpack area will also rise. If the water capacity of the backpack area is large, the amount of water required for the water area 101 at high tide will increase, thereby requiring the expansion of the water storage capacity of the bottom cylinder 2.

[0086] In the embodiment where the water launching area 104 is a water launching backpack, the first water launching pipe 105 and the second water launching pipe 106 may be two pipes provided separately, such as Figure 1 As shown, the first downcomer pipe 105 and the second downcomer pipe 106 are arranged side by side. The first downcomer pipe 105 and the second downcomer pipe 106 may also be connected to each other in a sleeve-type manner. Specifically, the second downcomer pipe 106 is sleeved outside the first downcomer pipe 105 .

[0087] In another specific embodiment of the present invention, please refer to the attached Figure 7 , attached Figure 7The specific embodiment of the present invention provides a structural schematic diagram of a water discharge area 104 located in a water area 101 and the water discharge area 104 is an outer pipe 122, a first water discharge pipe 105 and a second water discharge pipe 106 are arranged in the outer pipe 122, and the outer pipe 122, the first water discharge pipe 105 and the second water discharge pipe 106 constitute a triple overflow water discharge pipe. The top of the outer pipe 122 has a cover, and the upper and lower parts of the outer pipe 122 are respectively provided with second fish intercepting holes, and the second fish intercepting holes supply water in the water area 101 to flow into the water discharge area 104, and at the same time prevent the fish in the water area 101 from entering the water discharge area 104; the second water discharge pipe 106 is sleeved outside the first water discharge pipe 105.

[0088] When the water area 101 is low tide, when the water level is lower than the water inlet of the first down pipe 105, water is discharged only through the second down pipe 106. The discharge process is as follows: the water in the water area 101 enters between the outer pipe 122 and the second down pipe 106 through the second fish intercepting hole, and then the water overflows into the space between the second down pipe 106 and the first down pipe 105 through the water inlet of the second down pipe 106, and finally flows into the bottom tank 2. When the water area 101 is high tide, the electric ball valve 108 is closed, and the second down pipe 106 no longer discharges water. At this time, the first down pipe 105 does not discharge water because its water inlet is higher than the water level. Then only the first upper pipe 107 is feeding water into the water area 101, so the water area 101 begins to rise in tide. When the water level in the water area 101 is higher than the water inlet of the first downpipe 105, the first downpipe 105 starts to discharge water, and then the water intake of the first uppipe 107 and the water discharge of the first downpipe 105 gradually reach a balance, and the water area 101 reaches a high tide level.

[0089] In the embodiment where the water area 104 is located in the water area 101 and the water area 104 is an outer tube 122, only one inner tube 123 may be provided in the outer tube 122 to form a double overflow pipe structure. The diameter of the double overflow pipe is thinner than that of the triple overflow pipe, which is conducive to improving the viewing of the tidal tank. The upper and lower parts of the outer tube 122 of the double overflow pipe are provided with fish-blocking comb tubes, and the inner tube 123 is a downpipe, which is connected to the bottom tank 2 through the first drain pipe and the second drain pipe, and valves are provided on the first drain pipe and the second drain pipe. When both valves are open, water from the sewer pipe enters the sump 2 through the first drain pipe and the second drain pipe at the same time, the sewer flow is large, and the water area 101 is maintained at a low tide level; when the valve in one of the first drain pipe and the second drain pipe is closed, water from the sewer pipe can only enter the sump 2 through the other of the first drain pipe and the second drain pipe. At this time, the sewer flow decreases, and the water level in the water area 101 rises. The increase in the water level in the water area 101 will cause the overflow pressure to increase, so that the sewer flow gradually increases. At the same time, the increase in the water pump head causes the upstream flow to gradually decrease. When the water level in the water area 101 rises to a certain level, the upper and lower water flows reach a balance, and the water level in the water area 101 no longer rises, and is maintained at a high tide level.

[0090] The first drain pipe and the second drain pipe are connected to the bottom tank 2 through the main drain pipe. At least one of the first drain pipe, the second drain pipe and the main drain pipe is provided with a valve for reducing the noise of launching water at low tide.

[0091] Please refer to the attached Figure 8 -Attached Fig.10 , attached Figure 8 Schematic diagram of the structure of the tidal cylinder in an empty state when the land layer 117 is a beach. Fig. 9 Schematic diagram of the structure of the tidal cylinder at low tide when the land layer 117 is a beach. Fig.10 The schematic diagram of the structure of the tidal tank at high tide when the land layer 117 is a beach. If the land layer 117 of the land area 102 is only a beach and does not contain mud on the beach, then there is no need to consider the problem that the water containing mud on the beach flows into the water area 101 through the partition plate 103 and pollutes the water area 101. Therefore, the partition plate 103 at this time can be directly a flat plate. When the tide is high, the water level of the water area 101 will exceed the partition plate 103, directly submerging the land area 102, and the water level can rise higher. The water inlet of the first downpipe 105 should also be raised accordingly to match the higher tide. When the water level of the water area 101 rises to a sufficient height, aquatic fish and other organisms in the water area 101 will also swim to the land area 102 with the tide, thereby improving the ornamental value of the tidal tank.

[0092] The sand laid in the land area 102 should be slightly coarser, especially on the surface layer, and fine sand should not be laid, because at high tide, fine sand will float on the water due to surface tension. If the land layer 117 of the land area 102 is only sand, then fiddler crabs cannot be raised, but sand crabs and other creatures on the beach can be raised, and mangroves can also be planted.

[0093] Please refer to the attached Fig. 9 At low tide, the water level in the water area 101 is lower than the height of the partition plate 103, and the water in the water area 101 no longer flows into the land area 102. At the same time, the water flow of the first water pipe 107 and the water flow of the second water pipe 106 are balanced.

[0094] Please refer to the attached Fig.10 At high tide, the water in the water area 101 is connected with the water in the land area 102. The water flow of the first water pipe 107 is balanced with the water flow of the first water pipe 105.

[0095] The land layer 117 may be formed only of sand, or may be formed of sand and mud on the beach. Figure 2The lower layer of the land layer 117 is clean sand, and the upper layer is a mixture of sand and mud. A small area of ​​the upper layer can also be reserved for laying pure mud to meet the needs of some intertidal organisms. However, since the water permeability of mud is very poor, the area of ​​pure mud should not be too large to avoid difficulty in infiltration. In addition, mud has a certain viscosity and will only be washed away when the water flow is faster. The water flow that penetrates downward in the land area 102 is slow and will not wash away the mud.

[0096] The surface of the beach or tidal flat in the land area 102 contains organic matter (algae, nematodes, organic debris, etc.) that can be eaten by intertidal organisms. The algae and nematodes grow and multiply under conditions of suitable light, sand or tidal flat mud, suitable salinity, humidity, etc.; the organic debris mainly comes from the plankton and its remains, feed debris, fecal particles of aquatic organisms, etc. in the water area 101, and arrives at the land area 102 with the water flow when the water area 101 is high tide, and then remains on the surface of the land layer 117. Among them, the light can come from natural sunlight, or artificial light sources suitable for the growth of ordinary plants.

[0097] If the land layer 117 is composed of sand and mud on the beach, it is necessary to prevent the water in the water area 101 from being connected to the land area 102 through the space above the partition plate 103. If the water in the land area 102 and the water in the water area 101 are connected, the mud on the beach in the land area 102 will flow into the water area 101 with the tide, thereby polluting the water area 101. Therefore, in a specific embodiment of the present invention, the height of the partition plate 103 is set higher than the high tide level of the water area 101, and the overflow height of the partition plate 103 is lower than the height of the partition plate 103.

[0098] Please refer to the attached Fig.11 , attached Fig.11 This is a schematic diagram of the structure of the tidal tank when it is empty. Fig.11A connecting pipe 120 is provided on the partition plate 103 in the water area 101, and the connecting pipe 120 penetrates the partition plate 103. Water in the water area 101 can overflow into the land area 102 through the connecting pipe 120. The height of the connecting pipe 120 is the overflow height of the water area 101 overflowing into the land area 102. Then the connecting pipe 120 is lower than the high tide level of the water area 101 and higher than the low tide level of the water area 101. The flow cross section of the connecting pipe 120 is adjustable so that the water inflow of the land area 102 is greater than the water outflow of the land area 102, so that the water level of the land area 102 rises to submerge the land layer 117. The flow cross section of the connecting pipe 120 determines the high tide level of the land area 102. The high tide level of the land area 102 is lower than the connecting pipe 120. Specifically, a regulating valve can be provided in the connecting pipe 120, and the opening of the connecting pipe 120 can be adjusted by the regulating valve. If the pipeline of the regulating valve is long, the pipeline of the regulating valve can be directly used as the connecting pipe 120 to penetrate the partition plate 103. A fish blocking net needs to be set at the pipe opening of the connecting pipe 120 facing the water area 101 to prevent fish and other organisms in the water area 101 from entering.

[0099] For specific embodiments of the present invention, please refer to the attached Figure 6 A tide pool 116 is provided on the upper surface of the land layer 117 of the land area 102, and the tide pool 116 is located below the outlet of the connecting pipe 120. The tide pool 116 can be specifically a small dish. The function of the tide pool 116 is mainly to moderate the water flow and prevent the water flowing out of the connecting pipe 120 from directly impacting the mud and sand on the beach. The water flowing out of the outlet of the connecting pipe 120 first flows into the tide pool 116, and then overflows from the tide pool 116 to the surface of the land layer 117. In addition, the organisms in the land area 102 can enter the tide pool 116 to soak in the water. The inner wall surface of the tide pool 116 should be relatively rough. The rough inner wall surface of the tide pool 116 can be formed by providing an anti-slip grid plate on the inner wall surface, or by providing grooves and / or protrusions on the inner wall surface to form a rough inner wall surface of the tide pool 116, so as to facilitate the organisms to climb out of the tide pool and return to the land area 102. After the mud and sand on the beach are laid, the tide pool 116 is directly placed below the outlet of the connecting pipe 120. In order to improve the stability of the tide pool 116, the bottom of the tide pool 116 can be sunk into the land layer 117. This also reduces the distance between the pool mouth of the tide pool 116 and the upper surface of the land layer 117, thereby further reducing the impact of the water flow on the land layer 117, and at the same time facilitates various organisms in the land area 102 to crawl into the tide pool 116.

[0100] Some organisms in the tidal tank, such as mudskippers, frequently move back and forth between the land area 102 and the water area 101. If the mudskippers directly enter the water area 101 from the land area 102, the mud and sand stuck on the mudskippers will be brought to the water area 101, thereby polluting the water area 101. For this reason, the specific embodiment of the present invention is designed with a water tank 121, please refer to the attached Figure 1:The partition plate 103 includes a partition plate body 1031, and also includes a water tank 121 arranged on the side of the partition plate body 1031 facing away from the water area 101. The side of the water tank 121 close to the water area 101 is connected to the water area 101, so the water in the water area 101 can enter the water tank 121. The water tank 121 is connected to the front side plate and the rear side plate of the main cylinder 1 like the partition plate 103. The side of the water tank 121 away from the water area 101 has a first tank side plate 1032. The top surface of the first tank side plate 1032 is higher than the high tide level of the water area 101. The connecting pipe 120 is arranged on the first tank side plate 1032. When the organisms in the land area 102 enter the water area 101, they will first pass through the water tank 121. When passing through the water tank 121, the water in the water tank 121 will cause the mud and sand on the organisms to fall off, so that the organisms will not pollute the water area 101 after entering the water area 101. The mud and sand falling from the organisms will settle to the bottom of the water tank 121.

[0101] On the side of the water tank 121 close to the water area 101, the upper part of the partition plate body 1031 forms a second tank side plate of the water tank 121, and the top surface of the second tank side plate is lower than the low tide level of the water area 101. In this way, no matter the water area 101 is at a high tide level or a low tide level, the water in the water tank 121 and the water area 101 are connected, which is conducive to the circulation of water between the water tank 121 and the water area 101, and it is convenient to suck out the mud and sand in the water tank 121.

[0102] Please refer to the attached Fig.12 , attached Fig.12 The schematic diagram of the structure of the water-land tidal cylinder with the partition plate 103 arranged obliquely. The partition plate 103 as a whole gradually tilts from bottom to top toward the land area 102. This is closer to the natural coast effect. In addition, a non-slip grid plate 119 is provided on the side of the partition plate 103 close to the water area 101. The creatures in the water area 101, such as crabs, crawl into the land area 102 along the non-slip grid plate 119.

[0103] Please refer to the attached Figure 1-Figure 11 , is an embodiment in which the partition plate 103 is arranged in the vertical direction, and the partition plate 103 is not inclined toward the landing area 102. Figure 1 As shown, the bottom wall of the master cylinder 1 is arranged in the horizontal direction, and the partition plate 103 is perpendicular to the bottom wall of the master cylinder 1 .

[0104] Please refer to the attached Figure 1In order to prevent the sand in the land area 102 from entering the bottom cylinder 2 through the third downcomer pipe 112, a specific embodiment of the present invention sets a filter layer at the bottom of the land area 102. The land layer 117 is arranged above the filter layer. The filter layer blocks the sand and allows water to flow. In order to improve the smoothness of drainage, the present embodiment sets a bottom filter frame 114 below the filter layer. The bottom filter frame 114 is a grid frame with legs, and its function is to pad the filter layer and form a water flow space below it, which is conducive to the infiltration of water from the land layer 117 into the water flow space. The water seeping from the land layer 117 flows into the water flow space after being filtered by the filter layer, and then flows into the bottom cylinder 2 through the third downcomer pipe 112.

[0105] Please refer to the attached Figure 1 The filter layer is specifically nano bricks 113. Nano bricks are a kind of aquarium filter material, originally used for biochemical filtration of fish tanks. In this embodiment, nano bricks 113 are arranged below the mud layer of the land area 102, and their function is to intercept and filter particles such as sand in the water, while allowing water and mud on the beach to pass through.

[0106] The nanobrick 113 can be a whole nanobrick, or a combination of multiple small nanobricks. When splicing, it is necessary to seal the gaps on the upper surface with landscaping mud, cement and other materials, or seal it with a sealing ring, sealing strip, etc. to prevent sand from falling in.

[0107] A sealing ring is provided in the gap between the nano brick 113 and the cylinder wall of the land area 102 to prevent sand from falling into the water flow space.

[0108] In another specific implementation of the present invention, please refer to the attached Fig.13 , the filter layer is a filter screen 123. The filter screen 12 is a hard filter screen resistant to seawater corrosion, such as a titanium screen. The aperture size of the filter screen 123 is preferably such that it can intercept sand and can pass water and mud on the beach.

[0109] Please refer to the attached Fig. 9 , the land area 102 is only paved with clean sand and set as a beach. Since the water retention of sand is not as good as that of mud on the beach. After the tide goes out in the land area 102, the beach will be relatively dry. In order to ensure the humidity of the beach, the specific embodiment of the present invention is designed as follows: a nanobrick protrusion 122 is set below the nanobrick 113, and the nanobrick protrusion 122 protrudes toward the water flow space and can protrude to half the height of the water flow space. When the tide goes out in the land area 102, the water in the water flow space can penetrate upward into the beach through the nanobrick protrusion 122 and the nanobrick 113 to maintain the humidity of the beach.

[0110] The above scheme can also be used when the land area is an amphibious tidal tank with mud and mud.

[0111] The third downpipe 112 is provided with a regulating valve, which is used to adjust the water level in the water flow space. When the opening of the regulating valve is increased, the water level in the water flow space drops, the nanobrick protrusion 122 cannot touch the water surface, and the infiltration and water absorption stops. When the opening of the regulating valve is reduced, the water level in the water flow space rises, the nanobrick protrusion 122 can touch the water surface, and will infiltrate and absorb water upward. Therefore, by adjusting the regulating valve, the infiltration and non-infiltration water absorption can be controlled. The regulating valve can also reduce the noise of the third downpipe 112 when it is launched.

[0112] Please refer to the attached Figure 1 In addition to the first water pipe 107, the water pipe also includes a second water pipe 111. The water inlet of the second water pipe 111 is connected to the water outlet of the water pump 204. The water outlet of the second water pipe 111 is located in the water flow space, and the water outlet of the second water pipe 111 is provided with a branch pipe for changing the water outlet direction. The branch pipe is located in the water flow space to prevent water flow from impacting the filter layer. The branch pipe of the water outlet of the second water pipe 111 can also be in the horizontal direction or downward relative to the horizontal direction. Figure 1 As shown, the water outlet of the second water supply pipe 111 is connected to the middle of the branch pipe, and both ends of the branch pipe in the length direction can drain water.

[0113] Regulating valves are respectively provided on the second water supply pipe 111 and the first water supply pipe 107. Water from the water pump 204 can enter the water flow space through the second water supply pipe 111 to wash the bottom of the filter layer, thereby preventing the filter layer from being blocked.

[0114] The water outputted by the water pump 204 is simultaneously sent to the first water supply pipe 107 and the second water supply pipe 111. The regulating valves on the first water supply pipe 107 and the second water supply pipe 111 are used to adjust the flow rates in the first water supply pipe 107 and the second water supply pipe 111.

[0115] In order to prevent the water in the water area 101 from flowing back to the sump 2 during a power outage, an anti-siphon hole may be provided on the first water supply pipe 107 , or a check valve may be provided in the first water supply pipe 107 .

[0116] The tidal cylinder further includes a spray device 3 , which includes at least one nozzle 302 and a spray pipe 301 connected to the nozzle 302 . The water inlet of the spray pipe 301 is connected to a fresh water source for cleaning the inner wall of the main cylinder 1 .

[0117] In the embodiment where the spray device 3 has one nozzle 302, the nozzle is arranged above the middle position of the main cylinder, and can simultaneously wash the land area and the water area.

[0118] In the embodiment where the spray device 3 has at least two nozzles 302, a portion of the nozzles are located above the land area, and a portion of the nozzles are located above the water area.

[0119] The fresh water source can come from a water storage container, which is pumped by a pump; or from a water pipe equipped with a water purification device, which is controlled by a solenoid valve. The nozzle 302 is a wide-angle type, so that it can spray as horizontally as possible in all directions during spraying. When the water level in the water area 101 of the main cylinder 1 drops to low tide, the spray device 3 is turned on to flush the seawater attached to the cylinder wall into the water to avoid salt stains left on the cylinder wall after the seawater evaporates. The timing of spraying should be chosen after the water level in the water area 101 drops to low tide and before the seawater attached to the cylinder wall evaporates. This time is controlled by a timing switch. The main function of the spray device 3 is to keep the inner wall of the main cylinder 1 clean, which is beneficial to the ornamental effect.

[0120] Please refer to the attached Fig.14 and attached Fig.15 , attached Fig.14 This is a water level diagram of sump 2 at low tide in water area 101. Fig.15 The diagram is a water level diagram of the bottom cylinder 2 when the water area 101 is high tide. The bottom cylinder 2 of the tidal tank in the present invention is roughly the same as the bottom cylinder 2 of the common bottom filter type fish tank in structure, and its interior is divided into several functional grids 205, and a grid plate group is arranged between each two adjacent functional grids 205. The grid plate group includes a baffle plate 202 and an overflow plate 203 arranged relatively. The baffle plate 202 can guide the water flow so that the water flow can flow through each functional grid 205. The overflow plate 203 allows the water in one functional grid 205 to overflow into the next functional grid 205. If the water level of the bottom cylinder 2 exceeds the height of the baffle plate 202, the water flow will directly pass over the baffle plate 202, which will affect the filtering effect of the bottom cylinder 2. Therefore, the height of the baffle plate 202 determines the highest water level of the bottom cylinder 2. The overflow plate 203 can limit the lowest water level of the functional grid 205 in front of it. Since the second functional compartment 205 of the sump 2 along the water flow direction is usually a protein skimmer compartment (for placing a protein skimmer), the protein skimmer compartment needs to maintain a stable water level. When the water area 101 of the main cylinder 1 is in high tide, the water volume of the sump 2 decreases, and when the water area 101 of the main cylinder 1 is in low tide, the water volume of the sump 2 increases. In order to keep the water level of the protein skimmer compartment stable when the water volume of the sump 2 changes, the overflow plate 203 between the first two compartments, that is, the overflow plates 203 upstream and downstream of the protein skimmer compartment need to be appropriately raised, but the overflow plate 203 is still lower than the baffle 202, and the subsequent overflow plates 203 are appropriately lowered. In this way, the water volume changes of the sump 2 are all concentrated in the functional compartment 205 after the protein skimmer compartment. The heights of the two overflow plates 203 located upstream and downstream of the protein skimmer compartment can be equal, or the height of the overflow plate 203 located upstream of the protein skimmer compartment is 0cm-3cm higher than the height of the overflow plate 203 located downstream of the protein skimmer compartment.

[0121] Please refer to the attached Fig.16 and attached Fig.17 , attached Fig.16 This is a water level diagram of sump 2 at low tide in water area 101. Fig.17This is a water level diagram of the sump 2 when the water area 101 is high tide. If the land area 102 of the main tank 1 is set as a beach, and the water area 101 has a large tidal range, the water volume of the sump 2 will change greatly. At this time, the height of the baffle 202 of the sump 2 is basically the same as that of the baffle of a conventional bottom filter type fish tank, and the height of the overflow plate 203 is appropriately reduced, and the lower it is along the water flow direction, the lower it is in a step-like shape. In this way, even if the water volume of the sump 2 changes greatly, its baffle 202 and overflow plate 203 can still guide the water flow direction normally. At this time, the water volume of all functional grids 205 of the sump 2 can change, and the change amplitude is greater the further back it is.
