Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model provides a kind of power supply, drive unit of marine monitoring equipment, and described device is arranged on the detection facility of ocean, and its structural representation as shown in Figure 1, comprise phase transformation cylinder 1, piston 3, one-way valve I 4, accumulator 5, three-position three-way valve 6, oil hydraulic motor 7, generator 8, inner oil sac 9, one-way valve II 10,2/2-way valve 11 and outside oil sac 12; Wherein, phase transformation cylinder 1 is connected with inner oil sac 9 by one-way valve II 10, accumulator 5 is connected with phase transformation cylinder 1 by one-way valve I 4, accumulator 5 is also connected with the input end of a three-position three-way valve 6 simultaneously, the output terminal of three-position three-way valve is connected with the fluid input port of outside oil sac 12 and oil hydraulic motor 7 respectively, the fluid output port of oil hydraulic motor 7 is connected with inner oil sac 9, and outside oil sac is also connected with the input end of a 2/2-way valve 11, and the output terminal of 2/2-way valve 11 is connected with inner oil sac 9; Oil hydraulic motor 7 is connected with generator 8.Wherein, phase transformation cylinder 1 and outside oil sac 12 expose in the seawater, and itself and equipment are placed in pressure hull; The circulating direction of one-way valve II 10 is that inner oil sac 9 flows to phase transformation cylinder 1; The circulating direction of one-way valve I 4 is that phase transformation cylinder 1 flows to accumulator 5.
Wherein, the inner space of phase transformation cylinder 1 is divided into upper and lower two parts by piston 3, and phase transformation cylinder 1 upper space fills solid-liquid phase change material 2, and wherein, the liquidus density of solid-liquid phase change material 2 is greater than solid state density, and fusing point is between surface seawater and deep sea water; Outside oil sac 12 is full of hydraulic oil 13, and fill the nitrogen of hydraulic oil and certain pressure in accumulator 5, inner oil sac 9 is equipped with the hydraulic oil flowing to inner oil sac 9 equivalent with power generating stage accumulator 5.
Time initial, the utility model device is suspended in seawater surface with ocean detection facility, the gravity of ocean detection facility equals buoyancy, and phase transformation cylinder 1 and outside oil sac 12 expose in the seawater, and one-way valve I 4, one-way valve II10, three-position three-way valve 6 and 2/2-way valve 11 are all in nonconducting state.When equipment needs dive, left position put by 2/2-way valve 11, outside oil sac 12 and the conducting of inner oil sac 9.Under the effect of the hydraulic oil seawater pressure in outside oil sac 12, flow to inner oil sac 9, equipment volume reduces, and buoyancy reduces, equipment dive under gravity.Along with the increase of the degree of depth, density of sea water increases, and the buoyancy suffered by equipment increases gradually, and when the buoyancy that equipment is subject to equals gravity, equipment keeps state of suspension in predetermined depth.2/2-way valve 11 times right positions, outside oil sac 12 is in nonconducting state with inner oil sac 9; Meanwhile, along with the dive of equipment, ocean temperature reduces until below solid-liquid phase change material 2 fusing point, solid-liquid phase change material 2 solidifies, and volume reduces, and the pressure in phase transformation cylinder reduces.When the pressure in phase transformation cylinder is less than the pressure of inner oil sac 9, one-way valve 10 conducting.Hydraulic oil 13 in inner oil sac 9 flows to phase transformation cylinder 1, until solid-liquid phase change material 2 volume no longer changes.
When equipment needs to float, three-position three-way valve 6 puts left position, on state is between accumulator 5 and outside oil sac 12, now in accumulator 5, nitrogen pressure is greater than the outer seawater pressure of outside oil sac 12, hydraulic oil 13 flows to outside oil sac 12 by accumulator 5, equipment volume increases, and buoyancy is greater than gravity, starts to float.After outside oil sac 12 is full of, three-position three-way valve 6 times metas, are in nonconducting state.During the equipment arrival water surface, its buoyancy equals gravity, and equipment keeps state of suspension; Simultaneously, along with the floating of equipment, ocean temperature raises until exceed solid-liquid phase change material 2 melting point, solid-liquid phase change material 2 melts, and volume increases, pressure increase, until be greater than pressure in accumulator 5, one-way valve I 4 conducting, hydraulic oil 13 flows to accumulator 5 by phase transformation cylinder 1, until solid-liquid phase change material 2 volume no longer changes.
When equipment floats to sea, three-position three-way valve 6 puts right position, on state is between accumulator 5 and oil hydraulic motor 7, because pressure in accumulator 5 is higher than inner oil sac 9 pressure, hydraulic oil 13 flows to inner oil sac 9 by accumulator 5, drive oil hydraulic motor 7 to rotate, oil hydraulic motor 7 drive electrical generators 8 generates electricity.When accumulator 5 pressure drop is to initial value, three-position three-way valve 6 times metas, be in nonconducting state, generating completes.Now equipment gets back to original state, completes a work cycle.
Wherein, oil hydraulic motor also can be other turbines.
Also can by adding fixing wing plate and eccentric (change the position of device interior parts by corresponding mechanical mechanism thus change the device of whole equipment position of centre of gravity), or the wing plate of the angle of attack automatically can be regulated to change equipment moving attitude, make the floating dive vertical motion of equipment be converted into horizontal zigzagging.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
