Description

Technical Field

[0001] The invention relates to the technical field of vibration tables and flow-generating facilities, in particular to a vibration table hydraulic oil cooling system. Background Art

[0002] A large-scale vibration table is a device used to simulate earthquakes, wind vibrations, and other vibration environments. It is widely used in engineering, construction, aerospace, and seismic research. It typically consists of a highly rigid and stable platform and a vibration table tank. The structure or device under test is placed in the tank, and a motor, hydraulic system, or electromagnetic drive system generates vibrations of a specific frequency, subjecting the structure or device to mechanical vibrations of varying frequencies and amplitudes. Its advantages include simulating real-world environments, high load capacity, a wide frequency range, accuracy, repeatability, and accelerated test cycles. It is currently the most intuitive and effective large-scale device for studying seismic effects.

[0003] Vibration tables typically operate at high frequencies and for long periods of time, and their internal exciters are prone to overheating and shutting down. To ensure the vibration table remains operational, the exciter must be cooled. Large vibration tables have high power ratings and generate significant heat, necessitating the construction of cooling pools. However, existing cooling pools are limited in functionality, consume significant water, have low heat dissipation efficiency, and occupy a large area, leaving them idle when the vibration table is not in use. Summary of the Invention

[0004] The main purpose of the present invention is to provide a vibration table hydraulic oil cooling system to solve the above problems.

[0005] To achieve the above object, the present invention provides a vibration table hydraulic oil cooling system, 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] Cooling water tank, used to provide cooling water for water-to-water heat exchanger;

[0009] The cooling water pool includes an inner reservoir, a corridor and an outer reservoir arranged in sequence from the inside to the outside; two groups of partition walls are arranged in the corridor, and the two groups of partition walls divide the corridor into a left flow-making corridor and a right flow-making corridor, and inner and outer reservoir channels for connecting the inner reservoir and the outer reservoir are arranged under the partition walls; two groups of blocking walls are arranged in the outer reservoir, and the two groups of blocking walls divide the outer reservoir into a left outer reservoir and a right outer reservoir, and the left outer reservoir and the right outer reservoir are connected to the inner reservoir through an inner and outer reservoir channel respectively; the left flow-making corridor and the left outer reservoir, as well as the right flow-making corridor and the right outer reservoir, are connected through a pumping pipe and a return pipe.

[0010] Furthermore, 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. 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. The liquid inlet and liquid outlet of the liquid tank of the water-water heat exchanger are respectively connected to the right flow corridor and the left flow corridor.

[0011] Furthermore, two groups of partition walls are symmetrically distributed on both sides of the inner reservoir.

[0012] Furthermore, the oil-water heat exchangers and water-water heat exchangers are provided in multiple groups.

[0013] Furthermore, it also includes an upper water pool and an upper flow-generating corridor, which are both located on the top of the cooling water pool. The upper flow-generating corridor is connected to the left flow-generating corridor and the right flow-generating corridor, and the upper flow-generating corridor is connected to the upper water pool through a flow-generating pump.

[0014] The present invention has the following beneficial effects:

[0015] 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;

[0016] 2. Use the pumping pipe and the return pipe to form a pressure difference to make the reservoir water in the cooling pool flow and improve the heat dissipation efficiency;

[0017] 3. The cooling water pool in the present invention can be used as a flow-generating facility, thus preventing idle resources. Of course, if there is a flow-generating facility near the vibration table, the flow-generating facility can also be modified on a small scale to use as a cooling system, thus saving the cost of building a cooling water pool.

DETAILED DESCRIPTION

[0025] In order to achieve the above-mentioned objectives and effects, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0026] like Figure 1-6 As shown, the present invention provides a vibration table hydraulic oil cooling system, including

[0027] An oil-water heat exchanger 12 for cooling the hydraulic oil of the vibration table 11;

[0028] A water-to-water heat exchanger 13 is used to cool the oil-to-water heat exchanger 12;

[0029] A cooling water tank, used to provide cooling water for the water-to-water heat exchanger 13;

[0030] The cooling water pool includes an inner reservoir 1, a corridor and an outer reservoir arranged in sequence from the inside to the outside; two groups of partition walls 16 are arranged in the corridor, and the two groups of partition walls 16 are symmetrically distributed on both sides of the inner reservoir 1. The two groups of partition walls 16 divide the corridor into a left flow-making corridor 6 and a right flow-making corridor 7. A ramp 17 is provided under the partition wall 16, and an inner and outer reservoir channel 3 for connecting the inner reservoir 1 and the outer reservoir is provided in the ramp 17; two groups of blocking walls 15 are provided in the outer reservoir, and the two groups of blocking walls 15 divide the outer reservoir into a left outer reservoir 14 and a right outer reservoir 2. The left outer reservoir 14 and the right outer reservoir 2 are connected to the inner reservoir 1 through an inner and outer reservoir channel 3 respectively; the left flow-making corridor 6 and the left outer reservoir 14, as well as the right flow-making corridor 7 and the right outer reservoir 2, are connected through a pumping pipe 4 and a return pipe 5.

[0031] Both the oil-water heat exchanger 12 and the water-water heat exchanger 13 include a liquid tank and a heat pipe located within the tank. Both the liquid tank and the heat pipe are equipped with a liquid inlet and a liquid outlet. The heat pipe inlet and outlet of the oil-water heat exchanger 12 are connected to the hydraulic system of the vibrating table 11, while the heat pipe inlet and outlet of the water-water heat exchanger 13 are connected to the tank outlet and inlet of the oil-water heat exchanger 12, respectively. The tank inlet and outlet of the water-water heat exchanger 13 are connected to the right flow gallery 7 and the left flow gallery 6, respectively. Both the oil-water heat exchanger 12 and the water-water heat exchanger 13 are equipped with circulating pumps to ensure fluid flow. Because the hydraulic oil in the heat pipe of the oil-water heat exchanger 12 is under high pressure, purified water is used to cool it to protect the pipe. The water in the heat pipe of the water-water heat exchanger 13 is under lower pressure and can be cooled using water from a reservoir.

[0032] When in use, the hydraulic oil of the hydraulic system of the vibration table 11 circulates into the radiating pipe in the oil-water heat exchanger 12, and the pure water in the liquid tank of the oil-water heat exchanger 12 cools the radiating pipe in the oil-water heat exchanger 12; the pure water in the liquid tank of the oil-water heat exchanger 12 circulates into the radiating pipe in the water-water heat exchanger 13; the water-water heat exchanger 13 draws reservoir water from the right flow corridor 7 into the liquid tank of the water-water heat exchanger 13 to cool the radiating pipe in the water-water heat exchanger 13; the reservoir water in the liquid tank of the water-water heat exchanger 13 is discharged into the left flow corridor 6 after heat exchange, and the left When the reservoir water channel in the flow-making corridor 6 reaches a certain amount, the return water pipe 5 connected thereto is opened to discharge into the left outer reservoir 14. The pressure of the left outer reservoir 14 increases, and the pressure is released to the inner reservoir 1 through the inner and outer reservoir channels 3 connected thereto. The inner reservoir 1 releases the pressure to the right outer reservoir 2 through another inner and outer reservoir channel 3 until the water levels of the inner and outer reservoirs are level, thereby realizing flow heat dissipation. Compared with a static water pool, the heat dissipation efficiency is improved. When the reservoir water in the right flow-making corridor 7 drops to a certain amount, the pumping pipe 4 connected thereto is opened to pump water from the right outer reservoir 2 for replenishment.

[0033] In another embodiment, the oil-water heat exchanger 12 and the water-water heat exchanger 13 are provided in multiple groups to improve heat exchange efficiency.

[0034] In another embodiment, an upper water pool 10 and an upper flow-making gallery 8 are further included, wherein the upper water pool 10 and the upper flow-making gallery 8 are both located at the top of the cooling water pool, and the upper flow-making gallery 8 is communicated with the left flow-making gallery 6 and the right flow-making gallery 7, and the upper flow-making gallery 8 is communicated with the upper water pool 10 via a flow-making pump 9. When the vibration table 11 is not in use, the cooling system can be used as a flow-making facility and will not cause idle resources. Of course, when there is a flow-making facility near the vibration table, the flow-making facility can also be modified on a small scale and used as a cooling system to save the construction cost of the cooling water pool.

[0035] The above descriptions are only preferred embodiments of the present invention, not all embodiments. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.
