Description
Technical Field
[0001] This utility model relates to the field of plant cultivation technology for heavy metal experiments, and in particular to a plant cultivation device for heavy metal remediation experiments. Background Technology
[0002] The remediation of heavy metal-contaminated soil and water is a significant environmental issue. Phytoremediation, as an environmentally friendly and cost-effective method, has received widespread attention in recent years. Phytoremediation refers to the technology of removing pollutants from soil by utilizing the absorption, volatilization, transformation, degradation, and fixation of pollutants by plants and their rhizosphere microorganisms. Currently, many plants have been found to have a strong capacity for simultaneously accumulating multiple heavy metals, and heavy metals in the environment can be absorbed by plants.
[0003] In phytoremediation experiments for heavy metal pollution control, different plant species have significantly different requirements for growing space. When studying the ability of plants to absorb heavy metals, planting density is an important influencing factor. Too high a density may lead to competition for nutrients among plants and inhibit growth; while too low a density may not be able to reflect the community effect in the actual remediation scenario. Moreover, different plants have different space requirements.
[0004] Currently, many laboratories use disposable plastic containers or fixed-structure incubators for plant cultivation. This makes it impossible to flexibly adjust the size of the container according to the plant species, which limits the range of experimental subjects. Furthermore, the fixed planting holes or container volume make it difficult to support comparative experiments with different density gradients. In addition, the use of disposable materials not only increases the cost of experiments but also makes it easy for batch differences to lead to inconsistent experimental conditions. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of current plant cultivation containers, which are not adjustable and cannot meet the needs of experiments. When cultivating plants with different needs in one container, leakage of water and nutrient solution may occur, leading to inaccurate experimental data. Therefore, this invention proposes a plant cultivation device for heavy metal remediation experiments.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A plant cultivation device for heavy metal remediation experiments includes a culture box and a baffle. Multiple slots are provided on two opposite side walls inside the culture box, and multiple limiting slots are provided at the bottom of the culture box. The two ends of the limiting slots are connected to two slots. Two blocks are slidably connected to the upper surface of the baffle, and two connecting rods are connected to the lower surface of the two blocks. The two connecting rods on the blocks are located on both sides of the baffle. Horizontal plates are connected to both sides of the lower part of the baffle, and water-proof pads are provided on the lower surface of the horizontal plates and on the connecting rods.
[0008] By setting up the slots and baffles, different receiving cavities can be set up according to the experimental requirements. At the same time, the water-proof pad can seal the gap between the slots and baffles to prevent solution leakage.
[0009] Preferably, the baffle is provided with a groove, and a limit box is connected in the groove. A fixing plate is connected to the two side walls of the limit box. Two second sliding grooves are provided on the fixing plate. Two second sliders are slidably connected in each of the two second sliding grooves. A push rod is connected to the side of the second slider. The push rod passes through the side wall of the limit box and is connected to the corresponding connecting rod.
[0010] The second slider push rod can compress the water-proof pad, better filling the tiny gaps between the contact surfaces, thereby enhancing the sealing effect.
[0011] Preferably, a movable plate is slidably connected to the side wall inside the limiting box. Two sets of adjusting rods are connected to the lower surface of the movable plate. Each set of adjusting rods includes two tilting rods, which are correspondingly arranged with two second sliders on a second slide groove. Each second slider is provided with a connecting hole, which is corresponding to the tilting rod. The bottom of the two second slide grooves is provided with an opening. The lower ends of the two tilting rods pass through the connecting holes on the corresponding second sliders and extend to the bottom of the second slide grooves to the bottom of the fixed plate. A lead screw is rotatably connected to the top inside the limiting box. The lower end of the lead screw passes through the top of the limiting box and is rotatably connected to the upper surface of the movable plate.
[0012] The screw, moving plate, and tilting rod are designed to control the position of the corresponding second slider, thereby controlling the position of the connecting rod. The operation is simple: when in use, simply place the baffle in the corresponding slot and control the screw to rotate.
[0013] Preferably, the upper surface of the incubator is provided with multiple limiting blocks, the limiting blocks are correspondingly set with the slots, the opposite sides of the two limiting blocks are connected with limiting rods, and the two slots are provided with limiting holes, the limiting holes are correspondingly set with the limiting rods.
[0014] The limit rod and locking block on the limit block can limit the locking block and prevent it from moving up and down, thereby restricting the movement of the baffle and limiting the movement of the entire baffle.
[0015] Preferably, the incubator has a first groove on each of its two sides, a first slider is installed in the first groove, a support frame is connected to both first sliders, a conveying pipe is connected to the lower surface of the support frame, and multiple nozzles are connected to the conveying pipe.
[0016] The first slider and support frame can control the position of the nozzle delivering water, and set the corresponding plant in the receiving cavity at each position for watering or spraying nutrient solution. During the experiment, it can ensure that the conditions required by each plant are consistent.
[0017] Preferably, the bottom of the incubator is provided with multiple inclined grooves, which are inclined downwards in a direction away from the limiting groove.
[0018] The inclined tank allows excess nutrient solution to accumulate at the bottom, preventing leakage into the adjacent nutrient solution. Additionally, a discharge pipe can be installed at the bottom of the inclined tank to drain excess solution.
[0019] Compared with the prior art, the beneficial effects of this utility model are: by setting the slot and baffle, the required receiving cavity can be adjusted to meet the needs of different experiments. At the same time, by setting the second slider, push rod and connecting rod, the movement of the water-proof pad is controlled and the water-proof pad is squeezed, so that the water-proof pad is compressed, improving the sealing effect and ensuring the accuracy of the data during the experiment.

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0030] Reference Figures 1-7 A plant cultivation device for heavy metal remediation experiments includes a culture box 1 and a baffle 10. Multiple slots 5 are provided on two opposite side walls inside the culture box 1. The positions of the slots 5 are set according to the minimum accommodating cavity required in normal experiments, or the two ends of a limiting groove 15 are connected to the two slots 5. A baffle 10 can be placed between the two slots 5, forming an accommodating cavity with the two baffles 10 or the side walls of the culture box 1. When accommodating cavities of different sizes are needed, adjacent accommodating cavities can be merged into one, thereby increasing the accommodating cavity range. This can be adjusted according to experimental needs. Multiple limiting grooves 15 are provided at the bottom of the culture box 1. Two locking blocks 9 are slidably connected to the upper surface of the baffle 10. Two connecting rods 16 are connected to the lower surface of each locking block 9. The two connecting rods 16 on the locking blocks 9 are located on both sides of the baffle 10. Horizontal plates 24 are connected to both sides of the lower part of the baffle 10. Water-proof pads 17 are provided on the lower surface of the horizontal plates 24 and on the connecting rods 16. The water-proof pads 17 are... Figure 7 As shown, during operation, the protrusion of the water-proof pad 17 is located in the slot 5 or the limiting groove 15. The horizontal position of the water-proof pad 17 blocks the outside of the slot 5 or the limiting groove 15. The water-proof pad 17 is generally made of materials such as silicone rubber or PVC. Different materials can be used to block the solution as needed. When plants are planted in two adjacent containers, the water-proof pad 17 can isolate the two adjacent containers to prevent the culture medium or water from flowing from one container to another, thus affecting the accuracy of the experimental data. When plants are planted in only one container, it can also ensure that the nutrient solution or water does not leak, thus ensuring the accuracy of the experimental data.
[0031] Reference Figure 2 , Figure 5 and Figure 6 The baffle 10 has a groove, and a limit box 13 is connected inside the groove. The groove limits the limit box 13. A fixing plate 19 is connected to two side walls inside the limit box 13. The fixing plate 19 has two second sliding grooves 23. Two second sliders 20 are slidably connected in each of the two second sliding grooves 23. A push rod 11 is connected to the side of the second slider 20. The push rod 11 passes through the side wall of the limit box 13 and is connected to the corresponding connecting rod 16. The push rod 11 is connected to the side of the connecting rod 16. A moving plate 18 is slidably connected to the side wall inside the limit box 13. Two sets of adjusting rods are connected to the lower surface of the moving plate 18. One set of adjusting rods includes two tilting rods 21. The two tilting rods 21 are correspondingly set with the two second sliders 20 on one of the second sliding grooves 23. Each second slider 20 is provided with a connecting hole 12, and the connecting hole 12 is correspondingly set with the tilting rod 21. The bottom of the two second sliding grooves 23 is provided with an opening. The lower end of the two tilting rods 21 passes through the connecting rod on the corresponding second slider 20. The bottom of the connecting hole 12 and the second slide 23 extends to the bottom of the fixed plate 19. The lower end of the tilting rod 21 is connected to the mounting block 22, which limits the tilting rod 21 to prevent it from separating from the second slider 20. Since the connecting hole 12 is correspondingly set with the tilting rod 21, when the tilting rod 21 moves upward, it squeezes the second slider 20 through the connecting hole 12, thereby causing the second slider 20 to move. The second slider 20 pushes the push rod 11, which in turn pushes the connecting rod 16 to move. The connecting rod 16 moves toward the slot 5. The top of the limiting box 13 is rotatably connected to the lead screw 14. The lower end of the lead screw 14 passes through the top of the limiting box 13 and is rotatably connected to the upper surface of the moving plate 18. The lead screw 14 controls the moving plate 18 to move up and down, thereby controlling the tilting rod 21 below to move up and down and controlling the movement of the connecting rod 16. The connecting rod 16 controls the water-proof pad 17 to squeeze against the wall of the slot 5 and the side wall of the incubator 1, thereby increasing the penetration and waterproofing capabilities.
[0032] Reference Figure 1 , Figure 2 and Figure 4 The upper surface of the incubator 1 is provided with multiple limiting blocks 3, which are correspondingly set with the slots 5. The opposite sides of the two limiting blocks 3 are connected to limiting rods 4. The two slots 9 are provided with limiting holes 25, which are correspondingly set with the limiting rods 4. The slots 9 are U-shaped. The horizontal section of the slots 9 is slidably connected to the upper surface of the baffle 10. The two vertical sections of the slots 9 are movable with the two connecting rods 16 located on both sides of the baffle 10, thereby facilitating the movement of the slots 9. When the slots 9 move, the limiting rods 4 will be inserted into the limiting holes 25 on the slots 9, thereby limiting the vertical movement of the slots 9.
[0033] Reference Figure 1 and Figure 3 The incubator 1 has a first sliding groove 2 on each of its two sides. A first sliding block 7 is installed in the first sliding groove 2. A support frame 6 is connected to both first sliding blocks 7. A conveying pipe is connected to the lower surface of the support frame 6. Multiple nozzles 8 are connected to the conveying pipe. The first sliding blocks 7 facilitate the movement of the support frame 6. The support frame 6 drives the corresponding nozzles 8 to water or spray nutrient solution on the plants below. The first sliding blocks 7 are designed so that each container or even each plant in the container can be watered or sprayed with nutrient solution. The bottom of the incubator 1 has multiple inclined grooves. The inclined grooves are inclined downwards away from the limiting groove 15. When a large amount of water or nutrient solution needs to be sprayed in one container, if the water-proof pad 17 ages and is not replaced in time, the water and nutrient solution in the container will gather downwards, preventing the water or nutrient solution in that container from leaking into another container towards the limiting groove 15.
[0034] When in use, determine the size of the cultivation space according to the type of plant to be cultivated. Then, place both ends of the baffle 10 into the corresponding slots 5, with the bottom of the baffle 10 located in the limiting groove 15. The water-proof pad 17 on the lower surface of the horizontal plate 24 seals the area next to the limiting groove 15. Then, rotate the screw 14, which pushes the moving plate 18 downward. The moving plate 18 drives the tilting rod 21 downward as well. Due to the setting of the connecting hole 12, the tilting rod 21 will push the second slider 20 to move when it moves downward. The second slider 20 will drive the push rod 11 to move as well. The push rod 11 will push the connecting rod 16 to move as well. The connecting rod 16 will drive the water-proof pad 17 to move as well. The connecting rod 16 controls the water-proof pad 17 to seal the slot 5. Then, put in the soil containing the corresponding heavy metal and the seedlings or seeds of the corresponding plant. Place the corresponding nutrient solution according to the needs of the plant. When watering, water is applied through the delivery pipe and the nozzle 8. After watering one area, move the support frame 6 to the next position to continue watering.
[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
