[0023] The oil injection device proposed in the application embodiment will be further described below with reference to the accompanying drawings.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram of the oil injection device provided in an embodiment of this application. As shown in the figure, the oil injection device includes a base 10, a sealing container 20, a balloon device 30, and a regulating valve;

[0025] The base 10 includes a receiving cavity with an opening at one end, the receiving cavity being used to receive a micro-coke radiation source to be injected with oil;

[0026] The sealed container 20 is filled with insulating medium oil. The balloon device 30 is provided with an inlet and an outlet. The inlet of the balloon device 30 is connected to the oil outlet of the sealed container 20 through a first connecting pipe. The outlet of the balloon device 30 is connected to the oil injection port of the micro-coke radiation source to be injected through a second connecting pipe.

[0027] The regulating valve is disposed on the second connecting pipe, and the regulating valve is used to control the connection or disconnection of the second connecting pipe.

[0028] The micro-coke radiation source to be injected with oil is partially housed within the accommodating cavity of the base 10, while the remaining portion, including the oil injection port, is located outside the accommodating cavity of the base 10, facilitating connection with the second connecting pipe and improving the convenience of oil injection.

[0029] It should be understood that the balloon device 30 has a one-way function, the inlet end of the balloon device 30 is connected to the oil outlet of the sealed container 20 through the first connecting pipe, and the outlet of the balloon device 30 is connected to the oil injection port of the microfocus X-ray source to be injected through the second connecting pipe. In this way, during the contraction and expansion of the balloon device 30, the insulating medium oil in the sealed container 20 is sucked out through the first connecting pipe, and then injected into the microfocus X-ray source to be injected through the second connecting pipe and the oil injection port of the microfocus X-ray source to be injected, thereby realizing the oil injection of the microfocus X-ray source. The first connecting pipe and the second connecting pipe are both flexible soft pipes.

[0030] By providing an adjusting valve on the second connecting pipe, the adjusting valve can control the connection and interruption of the second connecting pipe. Specifically, under the condition that the connecting pipes are connected correctly, the adjusting valve is adjusted to the closed state to make the second connecting pipe in the connected state. In this way, during the contraction and expansion of the balloon device 30, the insulating medium oil in the sealed container 20 is sucked out through the first connecting pipe, and then injected into the microfocus X-ray source to be injected through the second connecting pipe and the oil injection port of the microfocus X-ray source to be injected; and in the case that the microfocus X-ray source is full of insulating medium oil, the adjusting valve is adjusted to the open state to make the second connecting pipe in the interrupted state, thereby realizing the closing of the oil injection device.

[0031] It should be noted that the adjusting valve can also control the flow rate and flow of the insulating medium oil, so that it is always in a liquid laminar flow state, so that the dry insulating medium oil flows along the pipe wall of the second connecting pipe and enters the microfocus X-ray source without generating bubbles or being brought into the microfocus X-ray source. Since the opening, closing and flow adjustment of the adjusting valve are common, this embodiment will not be described in detail.

[0032] In this way, the insulating medium oil in the sealed container 20 is sucked out by the balloon device 30 and injected into the microfocus X-ray source to be injected. The oil injection device has a simple structure, and when it is used to inject oil into different types of small-batch microfocus X-ray sources, the production cost can be reduced.

[0033] Optionally, the horizontal height of the sealed container 20 is greater than the horizontal height of the microfocus X-ray source to be injected.

[0034] In this embodiment, the horizontal height of the sealed container 20 is greater than the horizontal height of the microfocus X-ray source to be injected, so that a high-low pressure difference is formed between the sealed container 20 and the microfocus X-ray source to be injected, thereby reducing the risk of backflow of the insulating medium oil injected into the microfocus X-ray source. In this way, by using the principle of high-low differential pressure, the vacuum-dried insulating medium oil is injected into the microfocus X-ray source to be injected, which can reduce the flexibility of the compact and small microfocus source oil injection process, not only can improve the production efficiency of different types of small-batch microfocus sources, avoid occupying the batch production line resources, but also can ensure the performance stability.

[0035] In an alternative embodiment, two support frames of different heights can be provided, the sealed container 20 is placed on the higher support frame, and the microfocus X-ray source to be oiled is placed on the lower support frame, so that the sealed container 20 and the microfocus X-ray source to be oiled form a high-low pressure difference.

[0036] Optionally, as shown in Figure 2 The base 10 further comprises a first fixing rod 11, and the side wall of the accommodating cavity is provided with a first through hole, and the first fixing rod 11 is used to pass through the first through hole and abut against the microfocus X-ray source to be oiled.

[0037] In this embodiment, the cavity side wall of the accommodating cavity accommodating the microfocus X-ray source to be oiled is provided with a first through hole matched with the first fixing rod 11, so that the first fixing rod 11 can pass through the first through hole and abut against the microfocus X-ray source, so as to fix the microfocus X-ray source in the accommodating cavity.

[0038] It should be understood that the number of first through holes can be multiple, and the multiple first through holes are uniformly arranged on the cavity side wall of the accommodating cavity. Similarly, the first fixing rod 11 is arranged in each first through hole, so that the stability of the microfocus X-ray source to be oiled can be improved when the microfocus X-ray source to be oiled is located in the accommodating cavity.

[0039] In addition, when the cavity structure of the accommodating cavity and the size or shape of the microfocus X-ray source to be oiled do not match the cavity structure in the accommodating cavity, multiple first fixing rods 11 can also be arranged to pass through multiple first through holes and abut against the microfocus X-ray source, so as to fix the microfocus X-ray source in the accommodating cavity, thereby realizing the oiling of the microfocus X-ray source.

[0040] In an alternative embodiment, the first through hole can be a threaded hole, and the first fixing rod 11 matched with the threaded hole has a threaded structure, so that the first fixing rod 11 can be fixed by the engagement of the threads until the first fixing rod 11 abuts against the microfocus X-ray source to be oiled, thereby realizing the fixation of the microfocus X-ray source to be oiled.

[0041] Optionally, the accommodating cavity has a semicircular structure, and the base 10 further comprises a mounting plate 12 and first and second support blocks 13 and 14 oppositely arranged on the mounting plate 12. The first support block 13 is provided with a first arc-shaped groove, and the opening of the first arc-shaped groove faces the second support block 14. The second support block 14 is provided with a second arc-shaped groove, and the opening of the second arc-shaped groove faces the first support block 13. The semicircular structure is matched with the first and second arc-shaped grooves.

[0042] It should be understood that the mounting plate 12 and the opposing first support block 13 and second support block 14 form a concave structure, and the first support block 13 and the second support block 14 are respectively provided with a first arc-shaped groove and a second arc-shaped groove at their respective ends that are close to each other. The openings of the two arc-shaped grooves face each other to form a semi-circular groove. In this way, the bottom of the accommodating cavity with a semi-circular structure can be disposed within the groove.

[0043] The semi-circular structure can also be adjusted in angle within the groove along its extension direction. In this way, the micro-coke radiation source to be injected rotates with the rotation of the semi-circular structure, adjusting the oil injection port of the micro-coke radiation source to a suitable position to improve the oil injection efficiency of the oil injection device.

[0044] Optionally, the base 10 is a universal movable table base 10.

[0045] It should be understood that the universal movable table base 10 is a base 10 that can be adjusted at various angles. The microcoke radiation source to be injected is set on the universal movable table base 10 and can be adjusted at multiple angles along with the universal movable table base 10.

[0046] In this embodiment, by setting the base 10 as a universal movable table base 10, the angle of the micro-coke radiation source to be injected can be adjusted so that the oil injection port of the micro-coke radiation source to be injected is adjusted to a suitable position, thereby improving the oil injection efficiency of the oil injection device.

[0047] Optionally, the base 10 further includes a second fixing rod 15 and a third fixing rod 16. The first support block 13 is provided with a second through hole, and the second support block 14 is provided with a third through hole. The second fixing rod 15 is used to pass through the second through hole and abut against the semi-circular structure, and the third fixing rod 16 is used to pass through the third through hole and abut against the semi-circular structure.

[0048] In this embodiment, by providing a second fixing rod 15 and a third fixing rod 16, a second through hole adapted to the second fixing rod 15 is provided on the first support block 13, and a third through hole adapted to the third fixing rod 16 is provided on the second support block 14. In this way, the second fixing rod 15 can pass through the second through hole and abut against the receiving cavity, and the third fixing rod 16 can pass through the third through hole and abut against the receiving cavity, so that the receiving cavity can be fixed between the first support block 13 and the second support block 14.

[0049] It should be understood that there can be multiple second fixing rods 15 and multiple third fixing rods 16, and multiple second through holes and multiple third through holes. Multiple second through holes are evenly arranged on the first support block 13, and multiple third through holes are evenly arranged on the second support block 14. Similarly, a second fixing rod 15 is provided in each second through hole, and a third fixing rod 16 is provided in each third through hole. In this way, after adjusting the angle of the receiving cavity, the receiving cavity can be fixed by the relative support of the second fixing rods 15 and the third fixing rods 16.

[0050] In addition, when the angle to be adjusted of the accommodating cavity is large, multiple second fixing rods 15 passing through multiple second through holes and multiple third fixing rods 16 passing through multiple third through holes can be set to abut against the accommodating cavity to improve the stability of the accommodating cavity between the first support block 13 and the second support block 14.

[0051] In practice, when the insulating medium oil is about to fill the micro-coke radiation source to be injected, the regulating valve can be closed, the second fixing rod 15 and the third fixing rod 16 can be adjusted, and the semi-circular structure can be manually adjusted so that the micro-coke radiation source to be injected rotates with the semi-circular structure, thereby expelling the micro air bubbles inside the micro-coke radiation source and at the oil injection port. Then, the second fixing rod 15 and the third fixing rod 16 can be adjusted until they abut against the accommodating cavity, so that the accommodating cavity and the micro-coke radiation source to be injected inside the accommodating cavity are fixed. Then, the regulating valve can be opened again to inject oil until the oil injection is completed, and the regulating valve and the oil injection port of the micro-coke radiation source can be closed.

[0052] In an optional embodiment, the second through hole and the third through hole can be threaded holes, and the second fixing rod 15 and the third fixing rod 16 adapted thereto have threaded structures. In this way, through the engagement of the threads, the second fixing rod 15 and the third fixing rod 16 abut against the accommodating cavity, thereby achieving the fixation of the accommodating cavity.

[0053] Optionally, the base 10 further includes a locking member 17 disposed on the second support block 14, the locking member 17 being used to fix the semi-circular structure within the first arc-shaped groove and the second arc-shaped groove.

[0054] In this embodiment, by providing a locking member 17, when the accommodating cavity is fixed in the first arc-shaped groove and the second arc-shaped groove, the locking member 17 further fixes the accommodating cavity, thereby improving the reliability of the oil injection device.

[0055] Optionally, the second support block 14 is provided with a slide groove 141, the opening direction of the slide groove 141 is away from the mounting plate 12, and the locking member 17 is a slider adapted to the slide groove 141.

[0056] The slide groove 141 on the second support block 14 is provided along the extension direction of the second arc groove, and the slide groove 141 is located at the edge of the second arc groove. At this time, the locking member 17 is a slider that is adapted to the slide groove 141. The slider can slide in the slide groove 141. In this way, when the receiving cavity is rotated to the target angle, the slider can be slid to abut against the receiving cavity to fix the receiving cavity.

[0057] In practice, when the insulating medium oil is about to fill the micro-coke radiation source to be injected, the regulating valve can be closed, the second fixing rod 15 and the third fixing rod 16 can be adjusted, the slider can be slid out, and the semi-circular structure can be manually adjusted so that the micro-coke radiation source to be injected rotates with the semi-circular structure. After the micro air bubbles inside the micro-coke radiation source to be injected and at the oil injection port are expelled, the second fixing rod 15 and the third fixing rod 16 can be adjusted until they abut against the accommodating cavity. Then the slider can be slid until it abuts against the accommodating cavity, so that the accommodating cavity and the micro-coke radiation source to be injected inside the accommodating cavity are fixed. Then the regulating valve can be opened again to inject oil until the oil injection is completed. Finally, the regulating valve can be closed and the oil injection port of the micro-coke radiation source can be closed.

[0058] Optionally, the oil injection device further includes a worktable 40, and the base 10 is disposed on the worktable 40.
