Description

Technical Field

[0001] This invention relates to the field of underwater vibration environment simulation technology, and in particular to an underwater vibration environment simulation device and its usage method. Background Technology

[0002] Underwater shaking tables are crucial experimental devices for simulating underwater vibration environments. They not only provide a controllable and stable underwater vibration environment for marine engineering but also simulate the impact of marine environmental tests on offshore structures. To ensure accurate simulation of the marine environment, a current-generating device needs to be designed on the underwater shaking table. Due to the large size of the underwater shaking table and the large water flow required, existing facilities often store the water used for wave and current generation in an external reservoir. The external reservoir supplies water to the underwater shaking table, and the supplied water circulates between the external reservoir and the underwater shaking table to complete the current generation operation. The external reservoir increases the overall footprint of the device, raises construction costs, and hinders water flow, failing to effectively reduce the impact of the underwater shaking table on the surrounding environment.

[0003] Therefore, how to provide an underwater vibration environment simulation device and its usage method, reduce the overall footprint of the device, and reduce the impact of the underwater vibration table on the surrounding environment during the test has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide an underwater vibration environment simulation device and its usage method, which solves the problems of large overall equipment footprint caused by external reservoirs and significant vibration impact on the surrounding environment when the underwater vibration table is working.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention discloses an underwater vibration environment simulation device, including an annular reservoir, a flow-generating corridor, an underground water tank, and an underwater vibration table. The underwater vibration table is located inside the underground water tank, which is located at the center above the annular reservoir and is connected to the flow-generating corridor. The flow-generating corridor is connected to the annular reservoir.

[0007] Specifically, the annular reservoir includes an inner reservoir, an outer reservoir, and an inner-outer reservoir channel. Both the inner and outer reservoirs are annular reservoirs. The inner reservoir is located at the center of the outer reservoir ring, and the underground water tank is located at the center of the inner reservoir ring. The inner and outer reservoirs are connected by the inner-outer reservoir channel.

[0008] Specifically, the flow-generating corridor includes a lower flow-generating corridor and an upper flow-generating corridor. The lower flow-generating corridor is located within the ring formed between the inner reservoir and the outer reservoir. The lower flow-generating corridor exchanges water with the outer reservoir through a corridor pumping pipe and a corridor return pipe. Water stored in the outer reservoir is pumped into the lower flow-generating corridor through the corridor pumping pipe, and water in the lower flow-generating corridor flows back to the outer reservoir through the corridor return pipe.

[0009] The upper flow-generating corridor is located one floor above the lower flow-generating corridor and the two are connected by floor slab openings; the upper flow-generating corridor is connected to the underground water tank by a flow-generating pump.

[0010] Specifically, the inner and outer reservoir channels are located within the lower flow corridor, which divides the lower flow corridor into a left flow corridor and a right flow corridor.

[0011] Specifically, there are two symmetrically arranged upper flow channels located on both sides of the underground water tank, and multiple flow pumps are provided and evenly distributed within the upper flow channels.

[0012] The present invention also discloses a method of using the aforementioned underwater vibration environment simulation device, comprising the following steps:

[0013] Step 1, Water Injection: According to the test requirements, a specified amount of water is pumped from the outer reservoir into the lower flow-generating corridor through the corridor pumping pipe. The water in the lower flow-generating corridor overflows as it is pumped in through the corridor pumping pipe and enters the upper flow-generating corridor. Then, it enters the underground water tank through the flow-generating pump.

[0014] Step 2, Flow Generation: Select whether to start flow generation according to the test requirements. When flow generation is started, the flow generation pump in the upper flow generation corridor is turned on, and the water flows between the underground water tank, the upper flow generation corridor and the lower flow generation corridor under the pumping of the flow generation pump to complete the flow generation; when the flow generation ends, the flow generation pump is turned off.

[0015] Step 3, Water Return: Open the corridor return water pipe, and the water in the underground water tank flows back to the lower flow corridor under the action of gravity through the flow pump. The water in the lower flow corridor flows back to the outer reservoir under the action of gravity through the corridor return water pipe.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0017] This invention discloses an underwater vibration environment simulation device and its usage method. The device includes an annular reservoir, a flow-generating corridor, an underground water tank, and an underwater vibration table. The underwater vibration table is located inside the underground water tank, which is located at the center of the annular reservoir and connected to the flow-generating corridor. The flow-generating corridor is also connected to the annular reservoir. The usage method includes three steps: water injection, flow generation, and water return.

[0018] The present invention places the underwater vibration table inside a ring-shaped reservoir, which effectively reduces the overall footprint of the equipment and saves construction costs.

[0019] Surrounding the underwater vibration table with a reservoir can improve the overall foundation quality of the equipment and reduce the vibration impact of the underwater vibration table on the surrounding environment.

[0020] The water body remains inside the equipment throughout the injection, flow generation, and return operations. During these operations, the overall horizontal position of the water body does not change, and the stress on the overall structural foundation does not change, thus improving the safety and durability of the entire equipment.

[0030] like Figure 1-6As shown, the present invention provides an underwater vibration environment simulation device, including an annular reservoir, a flow-generating corridor, an underground water tank 1, and an underwater vibration table 2. The underwater vibration table 2 is located inside the underground water tank 1. The underground water tank 1 is located at the center above the annular reservoir and is connected to the flow-generating corridor. The flow-generating corridor is connected to the annular reservoir.

[0031] Specifically, the annular reservoir includes an inner reservoir 3, an outer reservoir 4, and an inner-outer reservoir channel 5. Both the inner reservoir 3 and the outer reservoir 4 are annular reservoirs. The inner reservoir 3 is located at the center of the outer reservoir 4 within the ring, and the underground water tank 1 is located at the center of the inner reservoir 3 within the ring. The inner reservoir 3 and the outer reservoir 4 are connected by the inner-outer reservoir channel 5.

[0032] In practical implementation, the capacity of the inner and outer reservoirs is determined by the functions of the equipment. The capacity of the inner reservoir 3 is fixed, while the capacity of the outer reservoir 4 can be further determined based on the required functions of the equipment. The annular shapes of the inner and outer reservoirs include square rings, circular rings, and elliptical rings.

[0033] Specifically, the flow-generating corridor includes a lower flow-generating corridor 6 and an upper flow-generating corridor 7. The lower flow-generating corridor 6 is located within the ring formed between the inner reservoir 3 and the outer reservoir 4. The lower flow-generating corridor 6 and the outer reservoir 4 exchange water through a corridor pumping pipe 8 and a corridor return pipe 9. The water stored in the outer reservoir 4 is pumped into the lower flow-generating corridor 6 through the corridor pumping pipe 8, and the water in the lower flow-generating corridor 6 flows back to the outer reservoir 4 through the corridor return pipe 9.

[0034] The upper flow-generating corridor 7 is located one floor above the lower flow-generating corridor 6 and the two are connected by floor slab openings; the upper flow-generating corridor 7 is connected to the underground water tank 1 by a flow-generating pump 10.

[0035] Specifically, the inner and outer reservoir channels 5 are located within the lower flow channel 6 and divide the lower flow channel 6 into a left flow channel 601 and a right flow channel 602.

[0036] Specifically, there are two symmetrically arranged upper flow channels 7 located on both sides of the underground water tank 1, and multiple flow pumps 10 are provided and evenly distributed within the upper flow channels 7.

[0037] Specifically, the inner reservoir 3, outer reservoir 4, inner and outer reservoir passage 5, lower flow corridor 6, corridor pumping pipe 8, and corridor return pipe 9 are located in the space of the third underground level, while the underground water tank 1, underwater vibration table 2, and upper flow corridor 7 are located in the space of the second underground level.

[0038] The present invention also provides a method of using the aforementioned underwater vibration environment simulation device, characterized by comprising the following steps:

[0039] Step 1, Water Injection: According to the test requirements, a specified amount of water is pumped from the outer reservoir 4 into the lower flow channel 6 through the channel pumping pipe 8. The water in the lower flow channel 6 overflows as it is pumped in through the channel pumping pipe 8 and enters the upper flow channel 7. Then, it enters the underground water tank 1 through the flow pump 10.

[0040] Step 2, Flow generation: Select whether to start flow generation according to the test requirements. When flow generation is started, the flow generation pump in the upper flow generation corridor 7 is turned on. The water flows between the underground water tank 1, the upper flow generation corridor 7 and the lower flow generation corridor 6 under the pumping of the flow generation pump to complete the flow generation. When the flow generation ends, the flow generation pump 10 is turned off.

[0041] Step 3, Water Return: Open the corridor return pipe 9. Under the action of gravity, the water in the underground water tank 1 flows back to the lower flow corridor 6 through the flow pump 10. Under the action of gravity, the water in the lower flow corridor 6 flows back to the outer reservoir 4 through the corridor return pipe 9.
