Since the insulation reinforcement needs to be carried out in a limited space for the high-voltage potential in the space, the X-ray device in the prior art is integrated in the box. When the X-ray device is working, high voltage will also be generated at both ends of the X-ray device, and the whole device will generate high voltage and flashover discharge to the external environment or between itself, so that the box will be charged, resulting in the staff being unable to touch the box, which is easy to cause safety hazards.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a high-voltage insulation protection device for a voltage doubling circuit applied to an X-ray device, comprising a first insulating protective shell 2 and a second insulating protective shell 3 which are covered on a voltage doubling circuit board 1, the first insulating protective shell being adjacent to the second insulating protective shell 3, and the first insulating protective shell 2 and the second insulating protective shell 3 being fixed by a connecting base 4, the first insulating protective shell 2 being provided with a first side panel 5, the second insulating protective shell 3 being provided with a second side panel 6, and an installation position 7 for installing an X-ray tube device (not shown in the figure) being provided between the first side panel 5 and the second side.
[0033] It should be noted that when the X-ray device is installed in the installation position 7, the high-voltage insulation protection device of the voltage doubler circuit and the X-ray device will be integrated and installed in a box after assembly. When the X-ray device is working, high voltage is generated on both sides of the voltage doubler circuit board 1 and at both ends of the X-ray device. At this time, flashover discharge is prone to occur to the external environment or between the device itself. At this time, the first insulating protective shell 2 and the second insulating protective shell 3 can increase the creepage distance between the voltage doubler circuit board 1 and the box, and the first side panel 5 and the second side panel 6 can increase the distance between the X-ray tube device and the box.
[0034] Compared with the prior art, in the technical solution of the utility model, the creepage distance between the voltage multiplier circuit board 1 and the box can be increased by the first insulating protective shell 2 and the second insulating protective shell 3, and the distance between the X-ray tube device and the box can be increased by the first side plate 5 and the second side plate 6, so that the overall equipment can generate high voltage without flashover discharge to the external environment or between itself, that is, the box is not charged, avoiding safety hazards. The device greatly enhances the creepage distance advantage in high voltage design, makes full use of the internal space of the X-ray device, and can make the size of the box smaller, that is, can reduce the design volume of high-voltage insulation, and effectively reduce the production cost.
[0035] Furthermore, the first side plate 5 is provided with a first notch 8 for facilitating installation of the wiring harness, a first insulating cover plate 9 is installed above the first notch 8, and the second side plate 6 is provided with a second notch 10 for facilitating installation of the wire harness, a second insulating cover plate 11 is installed above the second notch 10.
[0036] It can be understood that wiring harnesses are installed at both ends of the X-ray tube device, the first notch 8 and the second notch 10 can facilitate the installation of the X-ray tube device, and the first insulating cover plate 9 and the second insulating cover plate 11 can respectively increase the insulation design margin of the first notch 8 and the second notch 10, so that the X-ray tube device can generate a high voltage without flashover discharge to the external environment or between itself.
[0037] Furthermore, if Figure 1 As shown, the first insulating protective shell 2 and the second insulating protective shell 3 are provided with mounting grooves 12 for mounting insulating baffles. It should be noted that, according to the results of actual tests, other insulating baffles can be selectively installed on the mounting grooves 12 to increase the insulation design margin, so as to achieve the effect that the overall device generates high voltage without flashover discharge to the external environment or between itself.
[0038] Furthermore, if Figure 1 and Figure 2 As shown, the cross-sections of the first insulating cover plate 9 and the second insulating cover plate 11 are both L-shaped. It can be understood that, since the direction of creepage is scattered when the X-ray tube device generates high voltage, that is, creepage is performed in all directions at 360°, the cross-sections of the first insulating cover plate 9 and the second insulating cover plate 11 are both L-shaped, which can effectively insulate the first notch 8 and the second notch 10, respectively, thereby increasing the creepage distance between the first notch 8 and the second notch 10 and the box body, and preventing the box body from being charged.
[0039] Furthermore, if Figure 4 As shown, the first side plate 5 is provided with a first mounting hole 13, and the first insulating cover plate 9 is screwed to the first side plate 5 through the first mounting hole 13, and the second side plate 6 is provided with a second mounting hole 14, and the second insulating cover plate 11 is screwed to the second side plate 6 through the second mounting hole 14. It can be understood that the first side plate 5 and the first insulating cover plate 9 can be installed, and the second side plate 6 and the second insulating cover plate 11 can be installed through the first mounting hole 13 and the second mounting hole 14, and the installation process is simple and the assembly efficiency is high.
[0040] Furthermore, if Figure 3 As shown, the connection base 4 is arranged in a Y shape, and the connection base 4 can be used to connect the first insulating protective shell 2 and the second insulating protective shell 3 together, and can be fixed to the box body through the connection base 4.
[0041] Preferably, if Figure 3As shown, the connection base 4 includes a fixing plate 15, and fixing holes 16 are provided on both sides of the fixing plate 15. The first insulating protective shell 2 and the second insulating protective shell 3 are respectively fixed to the fixing plate 15 through the fixing holes 16 on both sides of the fixing plate 15. It can be understood that the first insulating protective shell 2 and the second insulating protective shell 3 are respectively fixed to the fixing plate 15 through the fixing holes 16 on both sides of the fixing plate 15, so that the first insulating protective shell 2 and the second insulating protective shell 3 can be arranged adjacent to each other.
[0042] Furthermore, if Figure 3 As shown, support members 17 are provided on both sides of the fixing sheet 15, and the support members 17 are arranged vertically with the fixing sheet 15, and the two support members 17 are respectively arranged in contact with the bottom of the first insulating protective shell 2 and the second insulating protective shell 3. It can be understood that the first insulating protective shell 2 and the second insulating protective shell 3 can be fixed together by the fixing sheet 15, and the support frame can be used to support the first insulating protective shell 2 and the second insulating protective shell 3, so that the first insulating protective shell 2 and the second insulating protective shell 3 and the fixing sheet 15 are installed more stably.
[0043] Furthermore, the tops of the first insulating protective shell 2 and the second insulating protective shell 3 are arranged in an arc shape. It should be noted that the first insulating protective shell 2 and the second insulating protective shell 3 can wrap most of the voltage doubler circuit board 1, and the tops of the first insulating protective shell 2 and the second insulating protective shell 3 are arranged in an arc shape, which greatly enhances the creepage distance advantage in high voltage design.
[0044] Furthermore, the first insulating protective shell 2 and the first side plate 5 are integrally formed, and the second insulating protective shell 3 and the first side plate 5 are integrally formed, which not only facilitates production and has lower costs, but also greatly enhances the creepage distance advantage in high voltage design.
[0045] In summary, the utility model provides a high-voltage insulation protection device for a voltage doubler circuit applied to an X-ray device. The first insulation cover plate and the second insulation cover plate can increase the insulation design margin, so that the X-ray tube device can generate high voltage without flashover discharge to the external environment or between itself. The mounting groove can be equipped with other insulation baffles to increase the insulation design margin. The cross-sections of the first insulation cover plate and the second insulation cover plate are both L-shaped, increasing the creepage distance between the first notch and the second notch and the box body to prevent the box body from being charged. The support frame can be used to support the first insulation shell and the second insulation shell, so that the first insulation shell and the second insulation shell and the fixing plate are installed more stably. The tops of the first insulation shell and the second insulation shell are arranged in an arc shape. The first insulation shell and the first side plate are integrally formed, and the second insulation shell and the first side plate are integrally formed, which greatly enhances the creepage distance advantage in the high voltage design.
