[0002] Mangroves are wetland woody plant communities mainly composed of evergreen trees or shrubs growing in the intertidal zone of tropical and subtropical coasts, which play an important role in purifying seawater, preventing wind and waves, storing carbon, and maintaining biodiversity. Chinese mangrove plants are mainly distributed in Guangdong, Guangxi, Hainan, Fujian, Zhejiang and other provinces.

[0003] Unlike other plants, mangrove plants mainly grow near the coast, and their growth is affected by the rising and falling tides and the salinity of seawater. In order to study and master the growth characteristics of mangrove plants, a planting tank for cultivating plants is needed. The traditional planting tank mainly comprises a tank body and a water supply system for supplying and draining water in the tank body.

[0040] It should be noted that the planting tank 200 has a planting body similar to the coastal soil, the mangrove plants are planted in the planting body, and the top ends of the water supply pipe 204 and the backwater pipe 205 penetrate the planting body and extend above the planting body. In addition, the water stored in the water storage cavity is salt water, and the salinity of the salt water is similar to that of the water on the coast, so that the growth environment on the coast can be simulated by the device.

[0041] The structure of the filter mechanism 300 will be described below:

[0042] The filter box 302 is a box body structure with an open top, and a filter assembly is arranged in the filter box 302. The lower portion of the first partition plate 201 is provided with a water outlet box 211, and an electromagnetic valve is arranged on the backwater pipe 205, and the end of the backwater pipe 205 is connected with the water outlet box 211. When the seat plate 301 is completely inserted into the filter cavity, the water outlet box 211 is located directly above the filter box 302. Therefore, the water in the planting cavity can enter the water outlet box 211 through the backwater pipe 205, then flow into the filter box 302 through the water outlet box 211, and then flow into the water storage cavity through the water outlet 303 and the water pipe 206 after being filtered by the filter assembly.

[0043] More specifically, the upper surface of the second partition plate 202 is provided with a sliding groove 212, and a displacement plate 304 is slidably arranged in the sliding groove 212. One end of the displacement plate 304 towards the seat plate 301 is rotatably provided with a main shaft 305, the main shaft 305 is fixedly connected with the seat plate 301, and the axial direction of the main shaft 305 is consistent with the length direction of the sliding groove 212. Therefore, the seat plate 301 and the displacement plate 304 can be rotatably connected through the main shaft 305.

[0044] Further, the filtering assembly comprises a plurality of filtering frames 306, which are rectangular frame-shaped, and the outer surfaces of the filtering frames 306 are all sleeved with sealing layers 307, the interiors of the filtering frames 306 are provided with fine filter screens 308, the filtering frames 306 are rotationally arranged in the filtering box 302, and the filtering frames 306 are sequentially arranged along the width direction of the filtering box 302, when the filtering frames 306 are in a horizontal posture, the sealing layers 307 on the adjacent two filtering frames 306 are tightly attached, meanwhile, the sealing layers 307 on the front and rear ends of the filtering frames 306 are also tightly attached with the inner front and rear sidewalls of the filtering box 302, which functions to allow the water flow to only pass through the fine filter screens 308 when the water flow drops on the filtering assembly.

[0045] It is worth mentioning that the bottom surface of the water outlet box 211 is provided with a plurality of drainage ports 213, the plurality of drainage ports 213 are one-to-one corresponding to the plurality of filtering frames 306, when the seat plate 301 is completely inserted into the interior of the filtering cavity, the plurality of drainage ports 213 are respectively located above the corresponding filtering frames 306. That is, when the water flow enters the interior of the water outlet box 211, the water flow can drop on the plurality of filtering frames 306 through the plurality of drainage ports 213, that is, the function of the drainage ports 213 is to allow the water flow to uniformly act on the plurality of filtering frames 306.

[0046] One sidewall of the filtering box 302 is provided with a plugging port, the plugging port is provided with a plugging block 309, the plugging block 309 is made of rubber material and has good sealing performance, which functions to avoid the water flow from flowing out of the plugging port; the interior of the filtering box 302 and below the filtering assembly is provided with a cleaning brush 310, the cleaning brush 310 is provided with guide rods 311 which are distributed along the length direction of the filtering box 302, one end of the guide rods 311 extends out of the filtering box 302 and is fixedly connected with the plugging block 309. Therefore, when the plugging block 309 is pulled, the plugging block 309 and the cleaning brush 310 can be synchronously moved, so that the cleaning brush 310 can be used to clean the impurity particles on the fine filter screen 308.

[0047] In another embodiment of the present application, one end of the filtering box 302 and away from the displacement plate 304 is provided with a mounting groove 312, the top surface of the seat plate 301 and away from the displacement plate 304 is fixedly provided with a rotating shaft 313, the top of the rotating shaft 313 extends into the mounting groove 312, and the filtering box 302 and the rotating shaft 313 are rotationally matched, the opening of the mounting groove 312 is provided with a cover plate 314, and the outer surface of the cover plate 314 is provided with a handle 315. The cover plate 314 is threadedly connected and fixed with the outer wall of the filtering box 302, the cover plate 314 functions to close the mounting groove 312, and when the user holds the handle 315 and pulls it outward, the seat plate 301 and the filtering box 302 can be pulled outwards.

[0048] One end of the filtering frame 306 is provided with a shaft 316, the end of the shaft 316 penetrates into the mounting groove 312, the end of the shaft 316 is also sleeved with a belt wheel 317, the outer sides of the belt wheels 317 are jointly sleeved with a synchronous belt, and the outer end of one of the shafts 316 is also provided with a first bevel gear 318; since the belt wheels 317 are linked through the synchronous belt, the filtering frames 306 can keep synchronous rotation, and the angles of the filtering frames 306 are always consistent. It should be noted that the end of the filtering frame 306 away from the shaft 316 is also provided with a rotating shaft, and the rotating shaft is rotationally connected with the inner wall of the filtering box 302.

[0049] In addition, the top end of the rotating shaft 313 is fixedly sleeved with a second bevel gear 319, the first bevel gear 318 and the second bevel gear 319 are meshed with each other, when the length direction of the filtering box 302 is parallel to the length direction of the seat plate 301, the front of the filtering frame 306 faces upward and keeps a horizontal posture; when the length direction of the filtering box 302 is perpendicular to the length direction of the seat plate 301, the back of the filtering frame 306 faces upward and keeps a horizontal posture. When the filtering box 302 rotates around the rotating shaft 313, the first bevel gear 318 can roll around the second bevel gear 319, so as to make the filtering frame 306 rotate, in particular, when the filtering box 302 rotates by 90°, the filtering frame 306 can rotate by 180° around the shaft 316.

[0050] In summary, in the specific implementation process of the embodiment, the water pump 203 is used to pump the water in the water storage cavity into the planting cavity, at the same time, the opening of the water return pipe 205 can be controlled by controlling the electromagnetic valve on the water return pipe 205, so as to discharge the water in the planting cavity, so as to realize dynamic circulation and simulate the water flow change of the ebb and flow of the sea. In addition, when the water return pipe 205 discharges water, the water flow can enter the water storage cavity through the water return pipe 205, the water outlet box 211, the filtering box 302 and the water passing pipe 206, wherein the filtering assembly in the filtering box 302 is used to filter the soil particles in the water flow, so as to ensure that the water entering the water storage cavity is filtered water.

[0051] In addition, the electromagnetic valves on the water pump 203 and the water return pipe 205 are electrically connected with the controller 400, that is, the timing work of the water pump 203 and the electromagnetic valves can be realized through the controller 400, so as to automatically simulate the ebb and flow effect.

[0052] It should be noted that after the filtering assembly is used for a period of time, a lot of soil impurities will accumulate on the filtering assembly, so the filtering assembly needs to be cleaned regularly. Specifically, when cleaning, the staff holds the handle 315 and forcibly pulls out the seat plate 301 until the seat plate 301 is completely pulled out, then rotates the filtering box 302 around the rotating shaft 313 by one quarter, then rotates the seat plate 301 by one quarter, so that the blocking block 309 is arranged downward, and the staff can clean the filtering assembly through the opening of the filtering box 302. Figure 4As shown; due to the rotation of the filter box 302, several filter frames 306 are rotated 180°, so that the originally upward-facing side of the filter frame 306 is arranged inwardly, and finally the blocking block 309 is pulled outwards, and the blocking block 309 is repeatedly lifted up and down, so that the cleaning brush 310 cleans the fine filter screen 308, and the dropped impurities can be dropped out of the filter box 302 through the blocking opening, facilitating the collection of the dropped impurities by the staff, thereby realizing the cleaning of the filter assembly.
