Description

Technical Field

[0001] The utility model relates to the technical field of power supply for a mobile CT medical vehicle, in particular to a simple and reliable battery power supply system for a mobile CT medical vehicle. Background Art

[0002] A mobile CT medical vehicle is a medical vehicle equipped with CT (computed tomography) equipment, usually used in emergency rescue, disaster medical rescue, medical services in remote areas and temporary medical activities. This type of vehicle can provide high-quality imaging diagnostic services, which helps medical personnel to diagnose and treat patients quickly and accurately. The biggest problem encountered by mobile CT medical vehicles during use is power supply. It is well known that CT machines are large medical diagnostic equipment with huge power consumption. The power of the X-ray generator part of the CT machine is between 50KW and 120KW, which does not include the attached motion control, image processing, etc. Therefore, the power supply problem restricts the development of mobile CT.

[0003] At present, there are two power supply methods for mobile CT medical vehicles. The first is external power supply, and the second is self-contained power (battery). The disadvantage of the external power supply method is that there are few units or users who can provide three-phase 380V high-power power supply. Even if there is a high-power power supply, it cannot be used due to the long wiring distance and the inability to disconnect the power for wiring. In addition, the wiring harness is very thick, long and heavy. Wiring is a technical job and a physical job. After the emergence of power batteries, most mobile CT medical vehicles use their own batteries. The battery output is DC, and CT machines are all AC powered, so a DC-to-AC inverter must be configured. The 50KW-120KW inverter is very large and takes up space in the vehicle. In addition, factors such as low conversion efficiency, high heat generation and high cost lead to poor use of the power supply method.

[0004] Therefore, there is an urgent need to provide a simple and reliable battery power supply system for a mobile CT medical vehicle to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that there are currently two power supply modes for mobile CT medical vehicles, the first is an external power supply mode, and the second is a self-contained power (battery) mode. The disadvantage of the external power supply mode is that there are very few units or users who can provide a three-phase 380V high-power power supply. Even if there is a high-power power supply, it cannot be used due to the long wiring distance and the inability to disconnect the power for wiring. In addition, the wiring harness is very thick, very long, and very heavy. Wiring is a technical job and a physical job. After the emergence of power batteries, most mobile CT medical vehicles use a self-contained battery mode. The battery output is DC, while CT machines are all AC-powered, so a DC-to-AC inverter must be configured. The 50KW-120KW inverter is very large and occupies space in the vehicle. In addition, factors such as low conversion efficiency, high heat generation, and high cost result in poor use of the power supply mode.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a simple and reliable battery power supply system for a mobile CT medical vehicle, including a CT machine, to which a first terminal, a second terminal and a third terminal are fixedly connected, a terminal G and a terminal N are fixedly connected, and the CT machine is connected to a power supply.

[0007] The utility model is further configured as follows: the power source is a 510V battery.

[0008] Through the above technical solution, the 510V battery is used as the wiring method for the three-phase 380V powered CT machine. The three-phase 380V power supply system can transmit the same power at a lower current. When transmitting power over long distances, the cross-sectional area and line loss of wires and cables can be reduced, thereby saving material costs and energy consumption.

[0009] The utility model is further configured as follows: the 510V battery is connected to the first terminal and the third terminal without distinguishing between positive and negative poles, and the second terminal is connected to the first terminal.

[0010] Through the above technical solution, not only the circuit structure is simplified, but also the cost of the system is reduced. Directly connecting the battery pack to the CT machine can reduce the risk of failure, improve the maintainability of the entire system, save space in the vehicle, obtain a stable voltage, and simplify the structure.

[0011] The utility model is further configured as follows: the connection method of the 510V battery can only be directly used when there is no power frequency transformer in the circuit.

[0012] Through the above technical solution, the industrial frequency transformer is often used to process AC power. Its design and working principle are based on the periodic changes of AC power. The battery provides DC power, which lacks the periodic changes of AC power. Therefore, the industrial frequency transformer cannot properly process DC power. The industrial frequency transformer is generally used for an operating frequency of 50Hz or 60Hz, and the DC power provided by the battery does not have the concept of frequency, so it cannot adapt to the working requirements of the industrial frequency transformer. The industrial frequency transformer is mainly used to convert the voltage of AC power, and the voltage regulation of DC power requires the use of other special DC power regulators. The industrial frequency transformer cannot achieve effective regulation of DC power.

[0013] The utility model is further configured as follows: the power source is a 310V battery.

[0014] Through the above technical solution, the 310V battery is used as the wiring method for the single-phase 220V power supply CT machine. Compared with the three-phase power supply system, the circuit design of the single-phase 220V power supply system is simpler, which makes power installation and maintenance more convenient, reduces cost and complexity, and under normal use, the lower voltage can reduce safety risks such as electric shock and fire, which is more beneficial to personal and property safety.

[0015] The utility model is further configured as follows: the 310V battery is connected to the first terminal and the terminal N, and the positive and negative poles are not distinguished.

[0016] Through the above technical solution, not only the circuit structure is simplified, but also the cost of the system is reduced. Directly connecting the battery pack to the CT machine can reduce the risk of failure, improve the maintainability of the entire system, save space in the vehicle, and obtain a stable voltage.

[0017] The utility model is further configured as follows: the connection mode of the 310V battery can only be directly used when there is no power frequency transformer in the circuit.

[0018] The beneficial effects of the utility model are as follows:

[0019] The utility model can reduce energy loss and improve the energy utilization efficiency of the whole system by directly connecting the power supply to the CT machine, avoid the use of inverter, and thus reduce the cost of the system. Directly connecting the power supply to the CT machine can reduce the risk of failure, improve the reliability and stability of the system, reduce the maintenance workload, improve the maintainability of the whole system, save space in the vehicle, obtain stable voltage, and simplify the structure.

The three-phase 380V power supply system can transmit the same power at a lower current. When transmitting power over a long distance, the cross-sectional area and line loss of wires and cables can be reduced, thereby saving material costs and energy consumption.

[0030] The 510V battery 601 is connected to the first terminal 2 and the third terminal 4, and the positive and negative poles are not distinguished. The second terminal 3 is connected to the first terminal 2; this not only simplifies the circuit structure, but also reduces the cost of the system. Directly connecting the battery pack to the CT machine 1 can reduce the risk of failure, improve the maintainability of the entire system, save space in the vehicle, obtain a stable voltage, and simplify the structure;

[0031] The connection method of 510V battery 601 can only be used directly when there is no industrial frequency transformer in the circuit; the industrial frequency transformer is often used to process AC power, and its design and working principle are based on the periodic changes of AC power, while the battery provides DC power, which lacks the periodic changes of AC power. Therefore, the industrial frequency transformer cannot properly process DC power. The industrial frequency transformer is generally used for an operating frequency of 50Hz or 60Hz, and the DC power provided by the battery does not have the concept of frequency, so it cannot meet the working requirements of the industrial frequency transformer. The industrial frequency transformer is mainly used to convert the voltage of AC power, and the voltage regulation of DC power requires the use of other special DC power regulators. The industrial frequency transformer cannot achieve effective regulation of DC power.

[0032] Embodiment 2:

[0033] See also Figure 1 , Figure 3 and Figure 5 , the power supply 6 is a 310V battery 602; the 310V battery 602 is a wiring method for a single-phase 220V power supply CT machine 1. Compared with a three-phase power supply system, a single-phase 220V power supply system has a simpler circuit design. This makes power installation and maintenance more convenient, reduces costs and complexity, and under normal use, lower voltage can reduce safety risks such as electric shock and fire, which is more beneficial to personal and property safety;

[0034] The 310V battery 602 is connected to the first terminal 2 and the terminal N7 without distinguishing between positive and negative poles; this not only simplifies the circuit structure but also reduces the cost of the system. Directly connecting the battery pack to the CT machine 1 can reduce the risk of failure, improve the maintainability of the entire system, save space in the vehicle, and obtain a stable voltage; the connection method of the 310V battery 602 can only be used directly when there is no industrial frequency transformer in the circuit.

[0035] Embodiment three:

[0036] See also Figure 1 , Figure 4 and Figure 5 The power supply 6 is a 510V battery 601 and a 310V battery 602. The 510V battery 601 is connected to the first terminal and the third terminal 4, and there is no need to distinguish between the positive and negative poles. The second terminal 3 is connected to the first terminal 2, the negative pole of the 510V battery 601 is connected to the negative pole of the 310V battery 602, and the positive pole of the 310V battery 602 is connected to the terminal N7; the 510V battery 601 and the 310V battery 602 are connected to the CT machine 1 as a three-way 380V and 220V power supply wiring method, which adapts to the diverse equipment and system requirements. Power supplies 6 with different voltages can meet the power requirements of different equipment, making the system design more flexible.

[0037] When the utility model is in use, there is no need to convert DC to AC through an inverter, and the power supply 6 is directly connected to the CT machine 1, which reduces energy loss and improves the energy utilization efficiency of the entire system. The use of an inverter can be avoided, thereby reducing the cost of the system. Directly connecting the power supply 6 to the CT machine 1 can reduce the risk of failure, improve the reliability and stability of the system, reduce the maintenance workload, improve the maintainability of the entire system, save space in the vehicle, obtain a stable voltage, and simplify the structure.
