Description of drawings
Fig. 1 is the internal structure sketch map that the present invention is used for the plug and play supply unit of mobile CT.
The specific embodiment
Below with reference to accompanying drawing, the specific embodiment of the present invention and embodiment are described in detail, described specific embodiment is not for limiting the specific embodiment of the present invention only in order to explain the present invention.
As shown in Figure 1, Fig. 1 is the internal structure sketch map that the present invention is used for the plug and play supply unit of mobile CT, and described mobile CT comprises that it is that the Frame of scan ring 130, annular is that the Cart of framework 120 and provided with wheels is frame 110 that the DISC of bulb 131 and high voltage package 132 is equipped with in inside; Described framework 120 is connected on the described frame 110 by mobile device, described framework 120 relative these frames 110 can move forward and backward along the axial direction of described scan ring 130, the described scan ring 130 adaptive inner spaces that are installed in described framework 120, and can do 360 ° around the axial line of described scan ring 130 self relative to this framework 120 and rotate.
The plug and play supply unit that the present invention is used for mobile CT comprises space rechargeable battery set 140, coupling piece 150, charging panel 160, electric pushrod 170, charging lock 180 and drive motors 185 thereof; Wherein, described electric pushrod 170, charging lock 180 and drive motors 185 thereof all are arranged on and maintain static on the moving framework 120 that only moves forward and backward, and described coupling piece 150, charging panel 160 and space rechargeable battery set 140 all are arranged on the described scan ring 130, can together rotate with described scan ring 130, and relatively described frame 110 moves forward and backward under the drive of described framework 120.
Adopt the satellite power supply technology to seek suitable space rechargeable battery set and provide power supply for high pressure, obtain energy by between DISC and Frame, building coupling circuit realization rechargeable battery set from external power.Adopt the satellite power supply method of supplying power to, reduced the machine works voltage peak; The power supply mode of this plug and play has finally realized providing for the high pressure of rotation on the DISC the new mode of electric energy, make mobile CT can be in 220V Power supply environment steady operation; And this scheme has also been broken away from the spark phenomenon that existing slip ring commonly used may occur.
When described bulb 131 rests on bottom initial position of described framework 120, described charging lock drive motors 185 promotes via described electric pushrod 170 to lift with described coupling piece 150 on the charging terminal of described charging lock 180 and contacts, and be that described space rechargeable battery set 140 is charged by described charging panel 160.
In the preferred implementation of the present invention for the plug and play supply unit of mobile CT, described high voltage package 132 is arranged on a side of described bulb 131, and described charging panel 160 is arranged on the opposite side of described bulb 131, and is symmetrical arranged with described high voltage package 132.
Concrete, described space set of cells 140 can comprise four Battery pack groups, the capacity of whole set of cells is approximately 5 * 10
6Joule, wherein three Battery pack groups and described bulb 131 are oppositely arranged, and another Battery pack group is arranged on the back side of described charging panel 160.In the situation of set of cells 100% capacity and no longer again charging, it is 120KV that scanning voltage is set, and sweep current is 45mA, and a circle is two seconds sweep time, but continuous sweep 140 circles.
For protecting the life-span of described space set of cells 140; in described scan ring 130, also battery detection plate 190 can be installed; cell voltage and charging and discharging currents for detection of described space set of cells 140; constantly monitoring voltage and charging and discharging currents are avoided described space set of cells 140 to work under the state that is lower than 44% electric weight and the phenomenon of battery overshoot occurred.
In a word, set up independently battery power management system in DISC, adopt space energy saving battery group as the power supply unit of high-pressure work, rotating when machine is not worked to initial position is that battery charges.
The process of charging for battery is jointly to be finished by the coupling piece 150 and the charging panel 160 that are installed in the charging lock 180 on the Frame and be installed on the DISC.When system does not work, middle control computer sends order makes DISC get back to initial bit, after detecting DISC and being parked in initial bit, lifts on the charging lock 180 on the Frame with coupling piece 150 on the DISC and contacts, for charging panel 160 provides electric energy, charging panel 160 namely can be the battery charging.
And the DISC rotation work is the discharge process for battery, and when machine works, charging lock 180 falls automatically, and set of cells is except the electric energy that provides for high pressure at this moment, and other electric energy are the miscellaneous part distribution of DISC by the low tension source plate 195 on the DISC.
Wherein, Cart is machinery bed, in other batteries and the power-supply management system that external power supply is converted to localpower arranged, on the one hand be that described space set of cells 140 is charged, for miscellaneous part electricity consumption in the machine, the control computer system also is arranged in the Cart in the while on the one hand.Frame is mobile before and after can be on frame, but non-rotatable, and coupling mechanism and communication interface system with DISC are installed on it, and the information that is used for finishing between Cart and DISC receives and sends.DISC is the rotary part in Frame, and the position shown in Fig. 1 is the initial position of DISC, and charging is lifted on the lock 180 and contact with coupling piece 150 is that battery charges.
Should be understood that; the above only is preferred embodiment of the present invention; be not sufficient to limit technical scheme of the present invention; for those of ordinary skills; within the spirit and principles in the present invention; can be increased and decreased according to the above description, replacement, conversion or improvement, and all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection domain of claims of the present invention.
