Description

Technical Field

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

[0002] An underwater vibration table is an important test equipment for simulating underwater vibration environments. It can 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. Normally, the vibration table has a high operating frequency and a long working time, and the internal exciter is prone to stop working due to excessive temperature. To ensure that the vibration table is always in working condition, the exciter needs to be cooled. Large vibration tables have high rated power and generate a lot of heat, so a cooling water pool needs to be built to cool them. However, the existing cooling water pools have a single function, consume a lot of water, have low heat dissipation efficiency, and occupy a large area. They are idle when the vibration table is not in use. How to provide an underwater vibration environment simulation device to improve the heat dissipation efficiency of the exciter and reduce water consumption while occupying a small area. Summary of the Invention

[0003] The purpose of the present invention is to provide an underwater vibration environment simulation device to solve the problems of existing cooling water pools having single function, high water consumption, low heat dissipation efficiency and large floor space.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The present invention provides an underwater vibration environment simulation device, comprising:

[0006] Oil-to-water heat exchanger for cooling the hydraulic oil of the vibration table;

[0007] Water-to-water heat exchanger, used to cool the oil-to-water heat exchanger;

[0008] underground water tanks to provide cooling water for water-to-water heat exchangers;

[0009] The underground water pool includes an inner reservoir, a corridor and an outer reservoir arranged in sequence from the inside to the outside; the corridor includes a lower flow-generating corridor and an upper flow-generating corridor, a plurality of rectifier plates are installed in the lower flow-generating corridor, the oil-water heat exchanger and the water-water heat exchanger are both installed in the lower flow-generating corridor, the lower flow-generating corridor and the upper flow-generating corridor are connected by an overflow hole, the lower flow-generating corridor and the outer reservoir are connected by a corridor pumping pipe and a corridor return pipe, and the inner reservoir and the outer reservoir are connected by inner and outer reservoir channels.

[0010] Preferably, a guide wall is installed inside the inner water reservoir, and a purified water outlet and a purified water inlet are provided on the outer water reservoir, and the purified water outlet and the purified water inlet are connected to an external water purification device through a pipeline.

[0011] Preferably, the inner reservoir and the outer reservoir are both annular reservoirs, the inner reservoir is located at the center of the outer reservoir ring, and the vibration table is located at the center of the inner reservoir.

[0012] Preferably, the upper flow-making corridor and the vibration pool above the vibration table are connected via a flow-making pump.

[0013] Preferably, the inner and outer reservoir channels are arranged in the lower flow-making corridor and the lower flow-making corridor is divided into a left flow-making corridor and a right flow-making corridor.

[0014] Preferably, the oil-water heat exchanger and the water-water heat exchanger both include a liquid tank and a heat dissipation pipe located in the liquid tank, and the liquid tank and the heat dissipation pipe are both 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 are connected to the hydraulic system of the vibration table, and the liquid inlet and liquid outlet of the heat dissipation pipe of the water-water heat exchanger are respectively connected to the liquid outlet and liquid inlet of the liquid tank of the oil-water heat exchanger, and the liquid inlet and liquid outlet of the liquid tank of the water-water heat exchanger are respectively connected to the lower flow-making gallery on the right and the lower flow-making gallery on the left.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] 1. The present invention uses a flow gallery partition wall to separate the water at the water outlet and water inlet of the water-to-water heat exchanger, ensuring the full implementation of the cooling process;

[0017] 2. The cooling water pool in the present invention can be used as a flow-generating facility, which will not cause idle resources. Of course, when there is a flow-generating facility near the vibration table, the flow-generating facility can also be modified on a small scale and used as a cooling system to save the cost of building a cooling water pool;

[0018] 3. The present invention provides a rectifying plate in the lower flow corridor to constrain and rectify the flowing water, thereby increasing the circulation speed of the cooling water in the lower flow corridor and further improving the cooling efficiency of the vibration table.

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.

[0033] The underground water pool 1 includes an inner reservoir 3, a gallery and an outer reservoir 4 arranged in sequence from the inside to the outside; the gallery includes a lower flow-making gallery 6 and an upper flow-making gallery 7, and a plurality of rectifier plates 14 are installed in the lower flow-making gallery 6. The oil-water heat exchanger 15 and the water-water heat exchanger 16 are both installed in the lower flow-making gallery 6. The lower flow-making gallery 6 and the upper flow-making gallery 7 are connected by an overflow hole, the lower flow-making gallery 6 and the outer reservoir 4 are connected by a gallery pumping pipe 8 and a gallery return pipe 9, and the inner reservoir 3 and the outer reservoir 4 are connected by an inner and outer reservoir channel 5.

[0034] Specifically, a guide wall 11 is installed inside the inner water reservoir 3, and a purified water outlet 12 and a purified water inlet 13 are provided on the outer water reservoir 4. The purified water outlet 12 and the purified water inlet 13 are connected to an external water purification device through a pipeline.

[0035] Specifically, the inner reservoir 3 and the outer reservoir 4 are both annular reservoirs, the inner reservoir 3 is located at the center of the outer reservoir 4 , and the vibration table 2 is located at the center of the inner reservoir 3 .

[0036] Specifically, the upper flow-generating corridor 7 and the vibration pool above the vibration table 2 are connected via a flow-generating pump 10 .

[0037] Specifically, the inner and outer reservoir channels 5 are arranged in the lower flow-making corridor 6 and divide the lower flow-making corridor 6 into a left flow-making corridor 601 and a right flow-making corridor 602 .

[0038] Specifically, the oil-water heat exchanger 15 and the water-water heat exchanger 16 both include a liquid tank and a heat dissipation pipe located in the liquid tank.
