Description

Technical Field

[0001] This utility model relates to the field of ecological simulation device technology, and in particular to a device for simulating mechanical damage to aquatic plants. Background Technology

[0002] In ecological restoration and aquatic plant stress resistance studies, simulating mechanical damage is crucial for assessing plant adaptability. Currently, the lack of devices capable of replicating the damage caused by water erosion and biological grazing hinders the reliability of these studies. Therefore, this study aims to design a device to simulate the combined damage caused by water erosion and biological grazing, thereby aiding in practical research and evaluation. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that lack devices capable of replicating the effects of water erosion and biological grazing, and to propose a device for simulating mechanical damage to aquatic plants.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for simulating mechanical damage to aquatic plants includes a culture box with a base;

[0006] Connect the water pipe, with one end fixed to the bottom of the breeding box and the other end fixed to the side wall of the breeding box;

[0007] A planting tray, which can be slidably installed inside the breeding box, is used to place aquatic plants, and its surface has through holes for the plant roots to extend.

[0008] The punch is fixedly installed on the inner side wall of the breeding tank and is in fluid communication with the connecting water pipe. It is used to form multiple streams of water to simulate the water flow scouring environment.

[0009] Multiple multi-bladed blades are installed on the bottom wall of the breeding box to simulate the damage caused by biological gnawing on the plant roots;

[0010] And a drive mechanism, including an inner slide and fan blades, for driving the multi-bladed blade to rotate via water flow.

[0011] In one possible design, the bottom of the breeding tank is fixedly connected to multiple side connecting cylinders, which are in fluid communication with the connecting water pipe. The rotating shaft of the multi-bladed blade is rotatably disposed inside the side connecting cylinder. The inner sliding cylinder is slidably disposed inside the side connecting cylinder and has a side hole on its side wall. The fan blade is fixedly disposed on the outer wall of the blade rod, and the blade rod is rotatably disposed inside the inner sliding cylinder. The top end of the blade rod is slidably sleeved with the rotating shaft of the multi-bladed blade. When the side hole of the inner sliding cylinder moves to the point of communication with the connecting water pipe and the side connecting cylinder, the water flow pushes the fan blade to rotate to drive the multi-bladed blade.

[0012] In one possible design, a connecting rod is fixedly connected to the bottom of the inner sliding cylinder, and the connecting rod extends through to the outside of the side connecting cylinder. A rubber sealing ring is provided at the penetration point. A lower connecting frame is fixedly connected to the bottom end of the connecting rod, and the lower connecting frame is slidably mounted on the outer wall of the breeding box.

[0013] In one possible design, an upper connecting frame is also included, which is slidably mounted on the outer wall of the breeding box and fixedly connected to the planting tray.

[0014] Guide rods are fixedly installed on the outer wall of the breeding box;

[0015] The sliding plate is slidably fitted onto the outer wall of the guide rod;

[0016] And the insert rods are fixedly installed on both sides of the skateboard;

[0017] The upper and lower connecting frames each have slots on their side walls, and the insert rods mate with the slots on the same side.

[0018] In one possible design, the punch is flat and elongated, and has multiple nozzles along its length.

[0019] In one possible design, an observation window is also included, located on the side wall of the cultivation box, for real-time observation of plant damage status;

[0020] And a pump, which is fixedly connected to the water pipe and used to drive the water flow.

[0021] In this application, when used in practice, aquatic plants are cultivated on the top of the planting tray, with their roots extending downwards. By controlling the pump connected to the cultivation tank, water is drawn out from one side of the cultivation tank and sent out to the other side. When sent out, the water is divided into multiple streams by the jet, which increases the speed of the water flow in the cultivation tank and achieves the effect of water scouring in the river.

[0022] By controlling the inner sliding cylinder to move downwards, the side hole on one side moves to the connection point between the water pipe and the side connecting cylinder. When the water flows through this point, it will push the fan blade to rotate, thereby driving the blade rod of the mounting pipe to rotate. The blade rod drives the rotating shaft of the multi-bladed blade to rotate, thereby driving the multi-bladed blade above to rotate. By controlling the multi-bladed blade to strike the roots of the plant, the damage caused by aquatic animals gnawing or violent scouring is simulated.

[0023] When the slide plate is slid to the right, the left-side insert disengages from the slot on the side wall of the upper connecting frame, thus releasing the upper connecting frame from its fixed position. This allows the upper connecting frame to control the up-and-down movement of the planting tray, ensuring that the plant roots can contact the multi-blade blade. When the slide plate is slid to the left, the right-side insert disengages from the slot on the side wall of the lower connecting frame, thus releasing the lower connecting frame from its fixed position. This allows the lower connecting frame to control the up-and-down movement of the inner sliding cylinder via the connecting rod. This controls whether the side hole on the side wall of the inner sliding cylinder connects to or disconnects from the connection point between the side connecting cylinder and the connecting water pipe, thereby controlling the opening and closing of the multi-blade blade.

[0024] In this utility model, the aquatic plant mechanical damage simulation device, through the adjustable structure of the planting tray, can ensure that the roots of the aquatic plants can contact the multi-bladed blades below during the simulation experiment, thereby ensuring the smooth progress of the experiment.

[0025] In this utility model, the aquatic plant mechanical damage simulation device, through the punch and multi-bladed blade, can achieve mechanical damage caused by water flow scouring or biological grazing damage caused by cutting, thereby simulating the actual river conditions.

[0026] In this invention, when in use, the pump is started to make the water flow through the punch to form multiple jets, thereby driving the water flow in the breeding tank to simulate the scouring environment of a river. The speed of the water flow below can be controlled to drive the rotation speed of the multi-bladed blades to strike the roots of the plants, simulating the damage caused by grazing.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] In one embodiment: Reference Figure 1-2 A simulation device includes: a breeding box 1, a connecting water pipe 3, a planting tray 4, and a multi-bladed blade 7. The bottom of the breeding box 1 is provided with a base, one end of the connecting water pipe 3 is connected to the bottom of the breeding box 1, and the other end is connected to a punch 6 in the middle of the side wall. The planting tray 4 is slidably set on the inner wall of the breeding box 1 through an upper connecting frame 5, and its surface is provided with through holes for the plant roots to extend.

[0034] refer to Figure 4 The bottom of the breeding box 1 is fixedly connected to multiple side connecting cylinders 14, which are arranged along the direction of the connecting water pipe 3. The bottom of the outer wall of the side connecting cylinder 14 is fixedly connected to the outer wall of the connecting water pipe. The rotating shaft of the multi-blade blade 7 is rotatably installed in each side connecting cylinder 14 through the mounting bracket. The inner sliding cylinder 15 is slidably installed inside the side connecting cylinder 14, and the side wall is provided with a side hole. The blade rod is rotatably installed inside the inner sliding cylinder 15. The fan blade 17 is fixed on the outer wall of the blade rod. When the inner sliding cylinder 15 moves to the bottom of the side connecting cylinder 14, the water flow will hit the fan blade 17 through the side hole, thereby driving the blade rod to rotate. The top of the blade rod is slidably sleeved with the rotating shaft of the multi-blade blade 7, thereby driving the multi-blade blade 7 to rotate and strike the roots of the plant. The flow rate of the water is controlled by the pump, thereby controlling the rotation speed of the multi-blade blade 7.

[0035] The punch 6 is fixedly installed on the side wall of the breeding box 1. It has a flat and long structure and multiple spray holes are opened along the length direction. The bottom of the breeding box 1 is fixedly installed with a pump connected to the water pipe 3. The side wall is provided with an observation window 2 to facilitate real-time observation of the plant damage status.

[0036] Specifically, by controlling the pump connected to the breeding tank 1, the water in the breeding tank 1 is drawn out from one side and sent out to the other side. When it is sent out, the water is divided into multiple streams by the jet 6, which drives the water flow speed in the breeding tank 1 and achieves the effect of water flow scouring in the river.

[0037] By controlling the inner sliding cylinder 15 to move downwards, its side hole moves to the connection point between the water pipe 3 and the side connecting cylinder 14. When the water flows through this point, it will push the fan blade 17 to rotate, thereby driving the blade rod of its mounting pipe to rotate. The blade rod drives the shaft of the multi-bladed blade 7 to rotate, thereby driving the multi-bladed blade 7 above to rotate. By controlling the multi-bladed blade 7 to strike the roots of the plant, the damage caused by aquatic animals gnawing or violent scouring is simulated.

[0038] Example 2

[0039] This application can be used in the field of ecological simulation devices, or in other fields applicable to this application.

[0040] In another embodiment: Reference Figure 3-4 A device for simulating mechanical damage to aquatic plants is applied to the field of ecological simulation devices. The upper connecting frame 5 and the lower connecting frame 12 are slidably set on the outer side wall of the breeding box 1. The upper connecting frame 5 is fixedly connected to the planting tray 4. The bottom of the inner sliding cylinder 15 is fixedly set with a connecting rod 16, the bottom end of which is fixedly connected to the lower connecting frame 12.

[0041] A guide rod 10 is fixedly installed on the outer wall of the breeding box 1. A slide plate 11 is slidably fitted on the outer wall of the guide rod 10, and a spring connected to the slide plate 11 is fitted on the outer wall of the guide rod 10. Insert rods 9 are fixedly installed on both sides of the slide plate 11. Slots 8 are opened on the side walls of the upper connecting frame 5 and the lower connecting frame 12 near the slide plate 11. The insert rods 9 are inserted into the slots 8 on the same side.

[0042] Specifically, when the slide plate 11 is slid to the right, the insertion rod 9 on its left side disengages from the slot 8 on the side wall of the upper connecting frame 5, thereby releasing the fixed state of the upper connecting frame 5. This allows the upper connecting frame 5 to control the planting tray 4 to move up and down, ensuring that the roots of the plant can contact the multi-blade 7. When the slide plate 11 is slid to the left, the insertion rod 9 on its right side will disengage from the slot 8 on the side wall of the lower connecting frame 12, thereby releasing the fixed state of the lower connecting frame 12. This allows the lower connecting frame 12 to control the inner sliding cylinder 15 to move up and down via the connecting rod 16. This controls whether the side hole on the side wall of the inner sliding cylinder 15 is connected to or disconnected from the connection point of the side connecting cylinder 14 and the connecting water pipe 3, thereby controlling the opening and closing of the multi-blade 7.

[0043] The lower connecting frame 12 has two slots 8 on its side wall to enable the multi-blade 7 to be started and stopped. The upper connecting frame 5 has multiple slots 8 on its side wall to enable multi-level adjustment of the height of the planting tray 4. The side wall of the breeding box 1 is equipped with a shell 13 to cover the sliding track of the slide plate 11.

[0044] However, as is well known to those skilled in the art, the working principle and wiring method of the pump are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
