Description

Technical Field

[0001] The utility model relates to the technical field of proton and heavy ion accelerators, in particular to a mobile vacuum vehicle device for proton and heavy ion accelerators. Background Art

[0002] The accelerator for proton and heavy ion cancer treatment needs to accelerate charged particles to 70% of the speed of light in a high vacuum environment in order to treat the patient's tumor. The vacuum pipeline, which is more than 200 meters long, is filled with magnets, beam diagnostics, linear accelerators and other equipment that perform multiple functions. Some of the equipment has its own requirements for the degree of vacuum, so the stability of the vacuum degree is the basic condition for the stable treatment of the accelerator.

[0003] Usually, a mobile vacuum truck is used to evacuate the vacuum system. However, when the mobile truck is in use, the external power grid fluctuates, causing the vacuum pump on the mobile truck to shut down. The shut-down vacuum pump is equivalent to a leak, which directly affects the stability of the vacuum degree. Currently, the power status of the vacuum pump on the mobile vacuum truck is observed by software to identify whether the vacuum pump is in normal working state or shutdown state. However, the software needs manual operation after identification. If the staff does not find it in the first time, the vacuum will start to leak. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art and provide a mobile vacuum vehicle device for a proton and heavy ion accelerator.

[0005] The utility model achieves the above technical effects through the following technical solutions:

[0006] A mobile vacuum vehicle device for a proton and heavy ion accelerator, the mobile vacuum vehicle device comprising:

[0007] A vacuum pumping device, the vacuum pumping device is used to evacuate the vacuum system;

[0008] A first moving vehicle, wherein the vacuum device is disposed on the first moving vehicle so as to move to a target position along with the first moving vehicle;

[0009] An uninterruptible power supply module is electrically connected to the vacuum pumping device and supplies power to the vacuum pumping device.

[0010] In this solution, by setting up an uninterruptible power supply module, the problem of vacuum pump shutdown caused by external power grid instability or switching, resulting in vacuum leakage, can be effectively solved. This solution is simple and easy to implement, and effectively reduces the downtime required to restore the vacuum system, avoiding irreversible damage to high vacuum equipment that may be caused by large-scale vacuum leakage.

[0011] Preferably, the mobile vacuum vehicle device further includes a second mobile vehicle, and the uninterruptible power supply module is arranged on the second mobile vehicle.

[0012] In this solution, the uninterruptible power supply module is arranged on the second mobile vehicle, which is convenient for movement. When needed, the input end is directly connected to the main power socket, and the output end is connected to the vacuum pumping device on the first mobile vehicle. One uninterruptible power supply module can supply power to different first mobile vehicles as needed, which is more flexible and maneuverable.

[0013] Preferably, the mobile vacuum vehicle device further includes a connecting member, and the first mobile vehicle and the second mobile vehicle are connected by the connecting member so that the first mobile vehicle and the second mobile vehicle move together.

[0014] In this solution, it can avoid the disconnection of the connecting wire between the uninterruptible power supply module and the vacuum pumping device during the movement. The connecting member can be elements such as ropes and clamps, with a simple structure and easy operation.

[0015] Preferably, a first electrical connector is arranged on the first mobile vehicle. One end of the first electrical connector is electrically connected to the vacuum pumping device, and the other end of the first electrical connector is electrically connected to the output end of the uninterruptible power supply module.

[0016] Preferably, the uninterruptible power supply module is arranged on the first mobile vehicle. A second electrical connector is arranged on the first mobile vehicle. One end of the second electrical connector is electrically connected to the vacuum pumping device, and the other end of the second electrical connector is electrically connected to the output end of the uninterruptible power supply module.

[0017] In this solution, integrating the uninterruptible power supply module on the first mobile vehicle makes the structure of the whole system more compact and also saves floor space.

[0018] Preferably, the mobile vacuum vehicle device further includes a main power supply. The input end of the uninterruptible power supply module is electrically connected to the main power supply, and the output end of the uninterruptible power supply module is electrically connected to the vacuum pumping device.

[0019] Preferably, the mobile vacuum vehicle device includes a third electrical connector and a plurality of the vacuum pumping devices. The plurality of vacuum pumping devices are respectively electrically connected to the third electrical connector, and the output end of the uninterruptible power supply module is electrically connected to the third electrical connector.

[0020] In this solution, by setting the third electrical connector, a plurality of vacuum pumping devices can be powered by one uninterruptible power supply module at the same time, with a simple structure, easy operation, and saving connecting wires.

[0021] Preferably, the uninterruptible power supply module includes a storage battery and an inverter that are electrically connected to each other.

[0022] Preferably, the capacity of the uninterruptible power supply module is between 800W and 2400W.

[0023] In this solution, although the rated power of the vacuum pumping device, such as a vacuum pump, is relatively large, the working current under the stable vacuum degree is very small. For example, for the Pfeiffer HiPace700 turbomolecular pump, the rated power is 400W, and only 40W is required during normal stable operation; the instability of the main power supply is at the second level, at most the minute level. Therefore, the capacity of the equipped uninterruptible power supply module does not need to be very large to solve the actual problem. For example, small uninterruptible power supply modules of 800W, 1600W, and 2400W can all meet the requirements.

[0024] Based on the common knowledge in the art, the above preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0025] The positive and progressive effects of the present invention are as follows: By setting up the uninterruptible power supply module, it can well solve the problem that the vacuum pump is shut down due to the instability or switching of the external power grid, resulting in vacuum leakage. This solution is simple and easy to implement, effectively reducing the downtime required to restore the vacuum system and avoiding the irreversible damage to the high-vacuum equipment that may be caused by large-area vacuum leakage.

[0042] The present utility model discloses a mobile vacuum vehicle device for a proton heavy ion accelerator. As Figure 1 and Figure 2 shown, the mobile vacuum vehicle device 100 includes a vacuum pumping device 101, a first mobile vehicle 102, and an uninterruptible power supply module 103. The vacuum pumping device 101 is used to pump the vacuum system; the vacuum pumping device 101 is disposed on the first mobile vehicle 102 to move to a target position along with the first mobile vehicle; the uninterruptible power supply module 103 is electrically connected to the vacuum pumping device 101 and supplies power to the vacuum pumping device 101.

[0043] In this implementation mode, by setting the uninterruptible power supply module 103, the problem of the vacuum pump being turned off due to unstable or switched external power grids, resulting in vacuum leakage, can be well solved. This solution is simple and easy to implement, effectively reducing the downtime required to restore the vacuum system and avoiding irreversible damage to high-vacuum equipment that may be caused by large-area vacuum leakage.

[0044] As Figure 1 shown, a first electrical connector 105 is disposed on the first mobile vehicle 102. One end of the first electrical connector 105 is electrically connected to the vacuum pumping device 101, and the other end of the first electrical connector 105 is electrically connected to the output end of the uninterruptible power supply module 103.

[0045] Preferably, the uninterruptible power supply module 103 is arranged on the first mobile vehicle 102. A second electrical connector 106 is arranged on the first mobile vehicle 102. One end of the second electrical connector 106 is electrically connected to the vacuum pumping device 101, and the other end of the second electrical connector 106 is electrically connected to the output end of the uninterruptible power supply module 103.

[0046] In this solution, the uninterruptible power supply module 103 is also integrated on the first mobile vehicle 102, making the structure of the entire system more compact and saving floor space.

[0047] It should be noted that the uninterruptible power supply module 103 can also be arranged in other positions. For example Figure 2 As shown, the mobile vacuum vehicle device 100 further includes a second mobile vehicle 104, and the uninterruptible power supply module 103 is arranged on the second mobile vehicle 104. Arranging the uninterruptible power supply module 103 on the second mobile vehicle 104 is convenient for movement. When needed, the input end is directly connected to the main electrical socket, and the output end is connected to the vacuum pumping device 101 on the first mobile vehicle 102. One uninterruptible power supply module 103 can supply power to different first mobile vehicles 102 as needed, which is more flexible and maneuverable.

[0048] The mobile vacuum vehicle device 100 further includes a connecting member. The first mobile vehicle 102 and the second mobile vehicle 104 are connected through the connecting member so that the first mobile vehicle 102 and the second mobile vehicle 104 move together. By providing the connecting member, the connection wire between the uninterruptible power supply module 103 and the vacuum pumping device 101 can be prevented from being disconnected during the movement process. The connecting member can be elements such as ropes and clamps, with a simple structure and easy operation.

The input end of the uninterruptible power supply module 103 is electrically connected to the main power supply 107, and the output end of the uninterruptible power supply module 103 is electrically connected to the vacuum pumping device 101.

[0050] In an alternative embodiment, the mobile vacuum vehicle device 100 includes a third electrical connector and a plurality of vacuum pumping devices 101. The plurality of vacuum pumping devices 101 are respectively electrically connected to the third electrical connector, and the output end of the uninterruptible power supply module 103 is electrically connected to the third electrical connector. By providing the third electrical connector, a plurality of vacuum pumping devices 101 can be powered by one uninterruptible power supply module 103 simultaneously, with a simple structure and easy operation, saving connection wires.

[0051] The uninterruptible power supply module 103 includes a storage battery and an inverter that are electrically connected to each other. The capacity of the uninterruptible power supply module 103 is between 800W and 2400W. Although the rated power of the vacuum pumping device 101, such as a vacuum pump, is relatively large, the operating current in the stable vacuum state is very small. For example, for the Pufa HiPace700 molecular pump, the rated power is 400W, and only 40W is required during normal stable operation; the instability of the main power supply is at the second level, at most at the minute level. Therefore, the capacity of the equipped uninterruptible power supply module 103 does not need to be very large to solve practical problems. For example, small uninterruptible power supply modules of 800W, 1600W, and 2400W can all meet the requirements.
