Description

Technical Field

[0001] The utility model relates to the technical field of test devices, in particular to a flood test device for simulating a flood discharge process. Background Art

[0002] Flood is a natural disaster with extremely destructive power. Wherever it goes, it will submerge farmland and houses, causing casualties and property losses. The submerged farmland will lead to reduced crop yields, which will cause food shortages and even famine.

[0003] In order to reduce the damage caused by floods to crops, agricultural experts will conduct flooding tests on crops, that is, simulate floods submerging crops, and then study the series of responses of crops after flooding, which is conducive to scientific prevention and disaster reduction when floods occur.

[0004] The prior art can simulate the flow of flood water and freely adjust the depth of flooding of crops when conducting flooding tests on crops, thereby improving the authenticity of the test. For example, the prior art discloses a flooding test device with publication number CN217352298U that simulates the flood flow process.

[0005] However, floods are often caused by severe weather such as heavy rain and typhoons. The flow of floods is accompanied by strong winds and rainfall, which cause flood waves. Existing technology cannot simulate wind, rain and waves, so the simulation effect of the experiment needs to be improved. Utility Model Content

[0006] To this end, the utility model provides a flooding test device for simulating a flood discharge process, so as to solve the problem in the prior art that the simulation effect of the test needs to be improved due to the inability to simulate wind, rain and waves.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] A flooding test device for simulating a flood flow process includes a test box, wherein a plurality of planting trays with crops are arranged inside the test box, and the planting trays are immersed in water inside the test box to simulate the situation where the crops are submerged by a flood and a flooding test is performed. A detachable cover is provided on the top of the test box;

[0010] The one-way hinge enables the push plate to push the water flow to generate waves when it moves toward the planting tray, and to rotate under the action of water flow resistance when it moves away from the planting tray, thereby reducing the resistance of the water flow.

[0011] The top of the cover is provided with a plurality of fans with adjustable directions, which can drive air to blow toward the water surface inside the test box, helping to form a wave effect. The top of the test box is provided with a rain simulation component for simulating rainfall.

[0014] Furthermore, a drive shaft is provided below the cover plate, the drive shaft is submerged in water, and the drive shaft is provided on the inner wall of the test box through a sealed bearing;

[0015] A motor for driving a drive shaft to rotate is fixedly provided at the outer end of the test box. Two impellers are fixedly provided at the outer end of the drive shaft. When the impellers rotate, thrust is generated to promote the flow of water inside the test box, simulating the turbulent flood situation.

[0016] Furthermore, the rainwater simulation component includes a top plate, and a hollow plate with a diversion function is fixed to the bottom end of the top plate.

[0017] Furthermore, a plurality of nozzles are fixedly provided at the bottom end of the hollow board, and the nozzles allow the water inside the hollow board to drip downward into the test box to simulate rainwater. A water pipe for conveying water is fixedly provided at the outer end of the hollow board.

[0018] Furthermore, each planting tray is provided with vertical plates on both the front and rear sides, and the vertical plates are fixed at the outer end of the test box. The top ends of the vertical plates extend to the top of the test box and are fixedly connected to the top plate, thereby supporting the entire rainwater simulation component.

[0019] Furthermore, a second linear motor is fixedly provided on the side of the vertical plate facing the planting tray, and a connecting arm is fixedly provided on the mover of the second linear motor. One end of the connecting arm is fixedly connected to the corresponding planting tray. The mover of the second linear motor is used to drive the planting tray to control the height of the planting tray, thereby controlling the depth to which the crops are submerged.

[0020] The utility model has the following advantages:

[0021] The first linear motor drives the push plate to reciprocate inside the test chamber, pushing the water flow inside the test chamber to move, thereby generating waves. At the same time, the fan is used to drive the air flow to blow towards the water surface, which helps to generate waves and simulate strong winds.

DETAILED DESCRIPTION

[0030] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0031] like Figure 1-5 As shown, the present invention provides a flood test device for simulating a flood discharge process, comprising a test box 1, wherein a plurality of planting trays 4 planted with crops are arranged inside the test box 1, and the planting trays 4 are submerged in the water inside the test box 1, and a detachable cover 6 is provided on the top of the test box 1;

[0032] Two first linear motors 12 are provided at the bottom end of the cover plate 6. A fixed beam 13 is provided at the bottom of the cover plate 6. The top end of the fixed beam 13 is fixedly connected to the two movers of the first linear motor 12. A push plate 14 is provided at the bottom end of the fixed beam 13 via a one-way hinge. The bottom end of the push plate 14 extends below the water surface.

[0033] A plurality of fans 5 with adjustable directions are provided on the top of the cover plate 6. The fans 5 can drive air to blow toward the water surface inside the test box 1, which helps to form a wave effect. A rain simulation component 3 for simulating rainfall is provided on the top of the test box 1.

[0034] Both ends of the fan 5 are provided with mounting plates through damping bearings, and the mounting plates are fixed to the top of the cover plate 6, so that the angle of the fan 5 can be adjusted, and then the direction of the airflow can be adjusted.

[0035] A planting tray 4 planted with crops is placed inside the test box 1 and submerged in water to simulate the situation where crops are submerged by floods, and a flooding test is conducted on the crops. During the test, the mover of the first linear motor 12 drives the fixed beam 13 and the push plate 14 to reciprocate inside the test box 1. The push plate 14 pushes the water flow during the movement, so that the water flow inside the test box 1 forms a wave effect. The one-way hinge enables the push plate 14 to push the water flow and generate waves when it moves toward the side close to the planting tray 4, and to rotate under the action of water flow resistance when it moves away from the planting tray 4, reducing the resistance of the water flow. At the same time, the fan 5 can drive the air flow and blow it toward the water surface to simulate wind force and help form waves. At the same time, the rain simulation component 3 can simulate rainfall to more realistically simulate the flood and weather conditions during the flood process, thereby improving the effect of the flooding test.

[0036] Water flows inside the test chamber 1 to simulate flooding. Figure 1 、 2As shown, a plurality of water inlet pipes 8 and a plurality of drainage pipes 9 are fixedly provided on both sides of the test box 1 . Water flows into the test box 1 through the water inlet pipes 8 and is discharged through the drainage pipes 9 , simulating a flood situation inside the test box 1 .

[0037] A drive shaft 10 is provided below the cover plate 6 , and the drive shaft 10 is submerged in water. The drive shaft 10 is provided on the inner wall of the test box 1 through a sealed bearing;

[0038] A motor 7 for driving a drive shaft 10 to rotate is fixedly provided at the outer end of the test box 1 . Two impellers 11 are fixedly provided at the outer end of the drive shaft 10 . The impellers 11 generate thrust when they rotate, thereby promoting the flow of water inside the test box 1 .

[0039] Water is input into the test box 1 through the water inlet pipe 8 and discharged through the drain pipe 9, so that the water flows inside the test box 1 to simulate a flood. During the simulation, the motor 7 is used to drive the drive shaft 10 and the impeller 11 to rotate. The rotation of the impeller 11 promotes the flow of water, increases the flow rate of the water, and can more realistically simulate the turbulent flood.

[0040] To simulate rainfall, Figure 3 As shown, the rainwater simulation component 3 includes a top plate 301 , and a hollow plate 302 with a diversion function is fixedly provided at the bottom end of the top plate 301 .

[0041] A plurality of nozzles 303 are fixedly provided at the bottom end of the hollow plate 302 , and the nozzles 303 allow the water inside the hollow plate 302 to drip downward into the test box 1 to simulate rainwater. A water pipe 304 for conveying water is fixedly provided at the outer end of the hollow plate 302 .

[0042] Water is fed into the hollow plate 302 through the water pipe 304 and dripped into the test box 1 through the nozzle 303, simulating heavy rainfall accompanied by floods in reality and improving the authenticity of the simulation.

[0043] During the experiment, it is necessary to adjust the different depths of flooding of crops, e.g. Figure 1 、 5 As shown, each planting tray 4 is provided with a vertical plate 2 on both the front and rear sides. The vertical plate 2 is fixed at the outer end of the test box 1. The top end of the vertical plate 2 extends to the top of the test box 1 and is fixedly connected to the top plate 301, thereby supporting the rainwater simulation component 3 as a whole.

[0044] A second linear motor 16 is fixedly provided on the side of the vertical plate 2 facing the planting tray 4, and a connecting arm 15 is fixedly provided on the mover of the second linear motor 16. One end of the connecting arm 15 is fixedly connected to the corresponding planting tray 4. The mover of the second linear motor 16 is used to drive the planting tray 4 to control the height of the planting tray 4.

[0045] The up and down movement of the mover on the second linear motor 16 can drive the connecting arm 15, and then drive the planting plate 4 to move up and down inside the test box 1, so as to adjust the height of the crops inside the test box 1 and then adjust the flooding depth of the crops.

[0046] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
