Description

Technical Field

[0001] The present invention relates to the field of underwater vibration environment simulation equipment, and in particular to a new underwater vibration environment simulation equipment. Background Art

[0002] An underwater vibration table is a crucial test device for simulating underwater vibration environments. It not only provides a controllable and stable underwater vibration environment for marine engineering projects, but also simulates the impact of marine environmental testing on offshore structures. To accurately simulate the marine environment, a flow-generating device must be designed into the underwater vibration table. Due to the large size of the underwater vibration table and the large flow rate it requires, existing facilities often store the water used for wave and flow generation in an external reservoir. Keeping the reservoir constantly full of water can easily lead to water deterioration, and due to the large volume of the reservoir, water replacement is difficult, necessitating regular water purification.

[0003] A common problem encountered with existing external reservoirs for water purification is that, after being transported back to the reservoir, the purified water mixes with the unpurified water already in the original reservoir. Due to the irregular flow of water within the reservoir, it is difficult for operators to determine whether the water in the reservoir has been purified to standard. For example, the water being drawn for purification may be already purified, and the unpurified water may not be drawn up due to the current, which can lead to misjudgment by the purification operator.

[0004] Therefore, how to develop a new underwater vibration environment simulation equipment, improve the purification effect of the water in the reservoir of the underwater vibration environment simulation equipment, and at the same time improve the heat dissipation efficiency of the underwater vibration table has become a technical problem that needs to be solved urgently by people in this field.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The movable reaction wall 5 is arranged at the center of the annular reservoir 1 and is used to support the underwater vibration table 3. The underwater vibration table 3 is located inside the underground water pool 2. The underground water pool 2 is located at the center above the annular reservoir 1 and is connected to the flow gallery. A guide wall 6 is installed inside the annular reservoir 1. A purified water outlet 7 and a purified water inlet 8 are provided on the annular reservoir 1. The purified water outlet 7 and the purified water inlet 8 are connected to an external water purification device through a pipeline. The water in the annular reservoir 1 flows in an orderly manner under the constraint of the guide wall 6.

[0063] The vibration platform hydraulic oil cooling system 4 includes an oil-water heat exchanger 401 and a water-water heat exchanger 402. The oil-water heat exchanger 401 is used to cool the hydraulic oil of the underwater vibration platform 3, and the water-water heat exchanger 402 is used to cool the oil-water heat exchanger 401. The flow gallery provides cooling water for the water-water heat exchanger 402.

[0064] Specifically, the provision of the guide wall 6 not only serves to guide the water body, but also serves to reduce the overall span of the equipment and provide support for the upper equipment.

[0065] Specifically, the annular reservoir 1 includes an inner reservoir 101, an outer reservoir 102 and an inner and outer reservoir channel 103. The inner reservoir 101 and the outer reservoir 102 are both annular reservoirs 1. The inner reservoir 101 is located at the inner center of the outer reservoir 102. The underground water pool 2 is located at the inner center of the ring one layer above the inner reservoir 101. The movable reaction wall 5 is arranged in the closed space enclosed by the underground water pool 2 and the inner reservoir 101. The inner reservoir 101 and the outer reservoir 102 are connected through the inner and outer reservoir channel 103.

[0066] Specifically, the capacity of the inner reservoir 101 and the outer reservoir 102 is determined by the function of the equipment. The capacity of the inner reservoir 101 is certain, and the capacity of the outer reservoir 102 can be further determined according to the required function of the equipment; the annular shapes of the inner reservoir 101 and the outer reservoir 102 include square rings, circular rings and elliptical rings.

The lower flow-making gallery 9 is located in a loop formed between the inner reservoir 101 and the outer reservoir 102. Water exchange is achieved between the lower flow-making gallery 9 and the outer reservoir 102 through a gallery pumping pipe 11 and a gallery return pipe 12. The water stored in the outer reservoir 102 is pumped into the lower flow-making gallery 9 through the gallery pumping pipe 11, and the water in the lower flow-making gallery 9 flows back to the outer reservoir 102 through the gallery return pipe 12.

[0068] The upper flow-generating gallery 10 is located one floor above the lower flow-generating gallery 9 and the two are connected by floor holes. The upper flow-generating gallery 10 is connected to the underground water pool 2 by a flow-generating pump 13 .

[0069] Specifically, the inner and outer reservoir channels 103 are arranged in the lower flow-making corridor 9 and divide the lower flow-making corridor 9 into a left flow-making corridor 901 and a right flow-making corridor 902;

[0070] The upper flow-generating corridors 10 are symmetrically provided with two of them and are located on both sides of the underground water pool 2 . The flow-generating pumps 13 are provided in plurality and are evenly distributed in the upper flow-generating corridors 10 .

[0071] Specifically, the inner reservoir 101, the outer reservoir 102, the inner and outer reservoir channels 103, the lower flow-generating gallery 9, the gallery pumping pipe 11, the gallery return pipe 12, and the movable reaction wall 5 are arranged in the lower space, the underground water pool 2, the underwater vibration table 3, and the upper flow-generating gallery 10 are arranged in the upper space, and the vibration table hydraulic oil cooling system 4 is arranged on either side of the equipment space on both sides of the underground water pool 2.

[0072] Specifically, the present invention also provides a water purification method using the novel underwater vibration environment simulation device, comprising the following steps:

[0073] Step 1: Pretreatment: Close the gallery pumping pipe 11 and the gallery return pipe 12;

[0074] Step 2, purification: open the purified water outlet 7 and the purified water inlet 8, and the water in the inner reservoir 101 flows unidirectionally and orderly from the inner and outer reservoir channels 103 to the outer reservoir 102 under the constraint of the guide wall 6. The water in the outer reservoir 102 is pumped from the purified water outlet 7 into the external water purification equipment for purification treatment. The purified water flows back to the outer reservoir 102 from the purified water inlet 8, and the water flowing back from the outer reservoir 102 flows back to the inner reservoir 101 from the inner and outer reservoir channels 103 on the other side.

[0075] Specifically, such as Figure 1 and 12 As shown, the oil-water heat exchanger 401 and the water-water heat exchanger 402 are arranged in multiple groups of two, and each of the oil-water heat exchanger 401 and the water-water heat exchanger 402 includes a liquid tank and a heat dissipation pipe located in the liquid tank, and the liquid tank and the heat dissipation pipe are provided with a liquid inlet and a liquid outlet. The liquid inlet and liquid outlet of the heat dissipation pipe of the oil-water heat exchanger 401 are connected to the hydraulic system of the underwater vibration table 3, and the liquid inlet and liquid outlet of the heat dissipation pipe of the water-water heat exchanger 402 are respectively connected to the liquid outlet and liquid inlet of the oil-water heat exchanger 401, and the liquid inlet and liquid outlet of the liquid tank of the water-water heat exchanger 402 are respectively connected to the left flow-making corridor 901 and the right flow-making corridor 902.

[0076] Specifically, the oil-water heat exchanger 401 and the water-water heat exchanger 402 are equipped with circulating pumps to ensure fluid flow. Since the hydraulic oil in the heat pipes of the oil-water heat exchanger 401 is under high pressure, purified water is used to cool it to protect the pipes. The water in the heat pipes of the water-water heat exchanger 402 is under low pressure and can be cooled using water from a reservoir.

[0077] Specifically, when the vibration platform hydraulic oil cooling system 4 is in use, the hydraulic oil of the hydraulic system of the underwater vibration platform 3 circulates into the radiating pipes in the oil-water heat exchanger 401, and the pure water in the liquid tank of the oil-water heat exchanger 401 cools the radiating pipes in the oil-water heat exchanger 401; the pure water in the liquid tank of the oil-water heat exchanger 401 circulates into the radiating pipes in the water-water heat exchanger 402; the water-water heat exchanger 402 draws reservoir water from the right flow corridor 902 into the liquid tank of the water-water heat exchanger 402 to cool the radiating pipes in the water-water heat exchanger 402; the reservoir water in the liquid tank of the water-water heat exchanger 402 is discharged into the left flow corridor 901 after heat exchange. When the water level in the reservoir channel of the left flow-making corridor 901 reaches a certain level, the corridor return pipe 12 connected thereto is opened to discharge the water into the left outer reservoir 102. The pressure in the left outer reservoir 102 increases, and the pressure is released to the inner reservoir 101 through the inner and outer reservoir channels 103 connected thereto. The inner reservoir 101 releases the pressure to the right outer reservoir 102 through another inner and outer reservoir channel 103 until the water levels of the inner and outer reservoirs are level, thereby realizing flow heat dissipation. Compared with a static pool, the heat dissipation efficiency is improved. When the reservoir water level in the right flow-making corridor 902 drops to a certain level, the corridor pumping pipe 11 connected thereto is opened to pump water from the right outer reservoir 102 for replenishment.
