Description

Technical Field

[0001] The invention relates to the technical field of planting tanks, in particular to a device for simulating the growth environment of mangroves near coasts. Background Art

[0002] Mangroves are wetland woody plant communities that grow in the intertidal zones of tropical and subtropical coasts and are composed of evergreen trees or shrubs with mangrove plants as the main body. They play an important role in purifying seawater, preventing wind and waves, fixing and storing carbon, and maintaining biodiversity. China's mangrove plants are mainly distributed in Guangdong, Guangxi, Hainan, Fujian, Zhejiang and other provinces.

[0003] Since mangroves mainly grow near the coast, unlike other plants, their growth is affected by the ebb and flow of the sea tide and the salinity of the seawater. In order to study and master the growth characteristics of mangroves, planting tanks for cultivating plants are needed. Traditional planting tanks are mainly composed of a tank body and a water supply system for filling and draining the tank body. However, in order to simulate the tidal characteristics of the coast, the planting tank also needs to constantly simulate the characteristics of wave scouring, which causes the water in the planting tank to contain a large amount of soil and sand impurities. When draining, the impurities will also be discharged along with the water.

[0004] Since the water in the planting tank is circulating, a filter mechanism is needed to filter out impurities in the return water. After a period of use, the filter mechanism will inevitably be blocked, so the staff needs to replace or clean the filter mechanism regularly. In order to facilitate the staff to maintain the planting tank and water supply system, we proposed a near-coast mangrove growth environment simulation device to solve the above drawbacks.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 - Fig.10 A device for simulating the growth environment of mangroves near the coast includes a base frame 100 and a planting tank 200 arranged on the top of the base frame 100. The interior of the planting tank 200 is provided with a first partition 201 and a second partition 202 from top to bottom. The top of the first partition 201 is a planting cavity, the space between the first partition 201 and the second partition 202 is a filter cavity, and the bottom of the second partition 202 is a water storage cavity. It should be noted that the first partition 201 and the second partition 202 are both in a horizontal posture, and the four sides of the first partition 201 and the second partition 202 are sealed by glass glue to prevent water leakage.

[0037] Furthermore, a water pump 203 is provided in the water storage chamber, and the water outlet of the water pump 203 is connected to a water pipe 204, and the free end of the water pipe 204 extends into the planting chamber, and a return pipe 205 is provided in the planting chamber, and the end of the return pipe 205 extends into the filter chamber; therefore, the water pump 203 can deliver the water in the water storage chamber into the planting chamber through the water pipe 204. In addition, a controller 400 is also provided outside the planting tank 200, and the signal output end of the controller 400 is connected to the water pump 203, that is, the staff can control the operation of the water pump 203 through the controller 400, such as setting a timed water supply, so that the staff does not need to manually start the water pump 203.

[0038] In addition, a filter mechanism 300 is provided in the filter cavity and below the end of the return pipe 205. The filter mechanism 300 includes a seat plate 301 and a filter box 302 provided on the seat plate 301. A water outlet 303 is provided on the side wall of the filter box 302. A water pipe 206 is provided on the second partition plate 202. The water pipe 206 is communicated with the water storage cavity. When the seat plate 301 is fully inserted into the filter cavity, the top of the water pipe 206 is aligned with the water outlet 303. That is, the water filtered by the filter box 302 can be discharged through the water outlet 303 and then enter the water storage cavity through the water pipe 206.

[0039] A return water box 207 is provided on the inner wall of the planting cavity, and the top end of the return water pipe 205 extends into the return water box 207. An opening is provided on the outer wall of the return water box 207, and a coarse filter screen 208 is provided in the opening to prevent large particles of soil from entering the return water box 207. An insertion port 209 is provided on the side wall of the planting cylinder 200 for the seat plate 301 and the filter box 302 to pass through, and a spring ball 210 is fixedly embedded in the inner bottom wall of the insertion port 209. The bottom surface of the seat plate 301 is provided with an embedding groove adapted to the spring ball 210. When the top ball of the spring ball 210 is embedded in the embedding groove, the outer end surfaces of the seat plate 301 and the filter box 302 are flush with the outer surface of the planting cylinder 200. At this time, the seat plate 301 is fully inserted into the filter cavity.

[0040] It should be noted that the planting tank 200 has a planting body with soil composition similar to that of the coastal soil, in which the mangrove plants are planted, and the top ends of the water supply pipe 204 and the water return pipe 205 both penetrate the planting body and extend above the planting body. In addition, the water stored in the water storage chamber is salt water, and the salinity of the salt water is similar to that of the coastal water, so that the device can simulate the growth environment of the coastal water.

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

[0042] The filter box 302 is a box structure with an open top, and a filter assembly is arranged inside the filter box 302; a water outlet box 211 is arranged below the first partition plate 201, and a solenoid valve is arranged on the water return pipe 205, and the end of the water return pipe 205 is connected to the water outlet box 211; when the seat plate 301 is fully 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 water return pipe 205, and then flow into the filter box 302 through the water outlet box 211, and after being filtered by the filter assembly, it flows into the water storage cavity through the water outlet 303 and the water pipe 206.

[0043] More specifically, a slide groove 212 is provided on the upper surface of the second partition plate 202, a displacement plate 304 is slidably provided in the slide groove 212, a main shaft 305 is rotatably provided at one end of the displacement plate 304 toward the seat plate 301, the main shaft 305 is fixedly connected to the seat plate 301, and the axial direction of the main shaft 305 is consistent with the length direction of the slide groove 212. Therefore, the seat plate 301 and the displacement plate 304 can be rotatably connected via the main shaft 305.

[0044] Furthermore, the filter assembly includes a plurality of filter frames 306, which are rectangular frame-shaped. The outer surfaces of the filter frames 306 are all covered with sealing layers 307, and the interior of the filter frames 306 is provided with fine filter screens 308. The filter frames 306 are rotatably arranged in the filter box 302, and the plurality of filter frames 306 are arranged in sequence along the width direction of the filter box 302. When the filter frames 306 are in a horizontal posture, the sealing layers 307 on two adjacent filter frames 306 fit tightly. At the same time, the sealing layers 307 at the front and rear ends of the filter frames 306 are also sealed to the front and rear side walls of the interior of the filter box 302, so that when water drips onto the filter assembly, the water can only pass through the fine filter screen 308.

[0045] It is worth mentioning that the bottom surface of the water outlet box 211 is provided with a plurality of drainage ports 213, which correspond to the plurality of filter frames 306 one by one. When the seat plate 301 is fully inserted into the filter cavity, the plurality of drainage ports 213 are respectively located directly above the corresponding filter frames 306. That is, when water flows into the water outlet box 211, it can drip onto the plurality of filter 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 act evenly on the plurality of filter frames 306.

[0046] A plugging port is formed through one side wall of the filter box 302, and a plugging block 309 is provided inside the plugging port. The plugging block 309 is made of rubber material and has good sealing performance, and its function is to prevent water from flowing out of the plugging port. A cleaning brush 310 is provided inside the filter box 302 and below the filter assembly. A guide rod 311 is provided on the cleaning brush 310. The guide rod 311 is distributed along the length direction of the filter box 302, and one end of the guide rod 311 extends out of the filter box 302 and is fixedly connected to the plugging block 309. Therefore, when the plugging block 309 is pulled, the plugging block 309 and the cleaning brush 310 can be pulled to move synchronously, so that the impurity particles on the fine filter screen 308 can be cleaned by the cleaning brush 310.

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

[0048] One end of the filter frame 306 is provided with a shaft 316, the end of the shaft 316 penetrates into the mounting groove 312, and the end of the shaft 316 is also provided with a pulley 317, and the outer sides of the plurality of pulleys 317 are provided with a synchronous belt, and the outer end of one of the shafts 316 is also provided with a first bevel gear 318; because the plurality of pulleys 317 are linked by the synchronous belt, the plurality of filter frames 306 can keep rotating synchronously, and the angles of the plurality of filter frames 306 are always consistent. It should be noted that the end of the filter frame 306 facing away from the shaft 316 is also provided with a rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the filter box 302.

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

[0050] In summary, in the specific implementation process of this embodiment, the water pump 203 is used to pump the water in the water storage chamber into the planting chamber. At the same time, the return pipe 205 can be controlled to open by controlling the solenoid valve on the return pipe 205, so as to discharge the water in the planting chamber, thereby realizing dynamic circulation and simulating the change of water flow at the seaside during high tide and low tide. In addition, when the return pipe 205 is draining water, the water flow can enter the water storage chamber through the return pipe 205, the water outlet box 211, the filter box 302 and the water pipe 206, wherein the filter assembly in the filter box 302 is used to filter the soil particles in the water flow, thereby ensuring that the water entering the water storage chamber is filtered water.

[0051] In addition, the water supply pump 203 and the electromagnetic valve on the return pipe 205 are both electrically connected to the controller 400, that is, the water supply pump 203 and the electromagnetic valve can be operated at a fixed time through the controller 400, thereby automatically simulating the effect of high tide and low tide.

[0052] It should be noted that after the filter assembly has been used for a period of time, a lot of soil impurities will accumulate on the filter assembly, so the filter assembly needs to be cleaned regularly. Specifically, when cleaning, the staff member holds the handle 315 and forcefully pulls the seat plate 301 outward until the seat plate 301 is completely pulled out, and then rotates the filter box 302 around the rotating shaft 313 by a quarter of a circle, and then rotates the seat plate 301 by a quarter of a circle, so that the blocking block 309 is set downward, such as Figure 4As shown; due to the rotation of the filter box 302, several filter frames 306 are rotated 180°, so that the upper side of the original filter frame 306 is set inward, and finally the blocking block 309 is pulled outward, and the blocking block 309 is repeatedly raised and lowered, so that the cleaning brush 310 cleans the fine filter 308, and the fallen impurities can fall out of the filter box 302 through the blocking port, which is convenient for the staff to collect the fallen impurities, thereby realizing the cleaning of the filter assembly.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
