[0036] like Figures 1-6As shown, the outer teeth of the third ratchet 8 are connected to the second chain 9, and the inner teeth of the second chain 9 are connected to the fourth ratchet 10.

The outer side of the first limiting rod is fixedly connected to the first baffle, and the lower side of the first toothed plate 12 is fixedly connected to a locking rod 13. Through the above technical solution, the second mounting sleeve can limit the second rotating shaft, so that the second rotating shaft can rotate in the second mounting sleeve and will not separate from the second mounting sleeve.
[0037] The first limiting rod and the first limiting plate can limit the first tooth plate 12 to move only along the direction of the first limiting groove.
[0038] like Figures 1-9 As shown, the outer teeth of the eighth ratchet 23 are connected to the fourth chain 22, and the eighth ratchet 23 is arranged in the first mounting top cover 3, the inner teeth of the fourth chain 22 are connected to the seventh ratchet 21, the middle of the seventh ratchet 21 is fixedly sleeved with the third rotating shaft, and the third mounting sleeve is movably mounted on the outer side below the third rotating shaft. The lower side of the third mounting sleeve is fixedly connected to the shed corridor 1, and the upper outer side of the third rotating shaft is fixedly sleeved with the sixth ratchet 20. Through the above technical solution, the third mounting sleeve can limit the third rotating shaft, so that the third rotating shaft can rotate in the third mounting sleeve without separating from the third mounting sleeve.
[0039] like Figures 1-9 As shown, the outer teeth of the sixth ratchet 20 are connected to the third chain 19, the inner teeth of the third chain 19 are connected to the fifth ratchet 18, the middle of the fifth ratchet 18 is fixedly sleeved with a fourth rotating shaft, the lower outer side of the fourth rotating shaft is movably mounted with a fourth mounting sleeve, the lower side of the fourth mounting sleeve is fixedly connected to the shed corridor 1, the outer side of the fourth rotating shaft is fixedly sleeved with a second gear 17, one side of the second gear 17 is toothed with a second tooth plate 16, the outer side of the second tooth plate 16 is abutted against a second limiting plate, and one side of the second limiting plate is provided with a first gear 17.

Through the above technical solution, the fourth mounting sleeve can limit the fourth rotating shaft, so that the fourth rotating shaft can rotate in the fourth mounting sleeve without being separated from the fourth mounting sleeve;
[0040] In addition to the position where the second tooth plate 16 and the locking plate 14 are fixedly connected, a gap is left between the second tooth plate 16 and the locking plate 14, so that when the locking rod 13 is inserted into the locking hole 15, the first tooth plate 12 driven by the locking rod 13 will enter the gap between the second tooth plate 16 and the locking plate 14, and will not interfere with the movement of the first tooth plate 12;
[0041] When the locking hole 15 is not aligned with the locking rod 13 , the movement of the locking rod 13 will be interfered by the locking plate 14 , thereby limiting the locking rod 13 .
[0042] like Figure 1-Figure 3 、 Figure 10 As shown, a shed body 25 is fixedly connected to one side of the shed corridor 1, and a second mounting top cover 26 is fixedly connected to the top of the shed body 25. A cross partition 27 is fixedly connected to the inside of the second mounting top cover 26. Four ventilation fans 28 are fixedly connected to the upper inner wall of the shed body 25 at equal distances. Ventilation components are installed on the outsides of the four ventilation fans 28. The four groups of ventilation components are arranged symmetrically with the center. The ventilation components include connecting holes, which are opened at corresponding positions of the ventilation fans 28 on the upper outside of the shed body 25. A limiting ring 29 is fixedly connected to the corresponding position on the outside of the connecting hole above the shed body 25, and a ventilation cylinder 30 is movably installed on the outside of the limiting ring 29. Through the above technical solution, the ventilation fan 28 can be connected to the space inside the second mounting top cover 26 through the connecting hole. The cross partition 27 divides the space inside the second mounting top cover 26 into four installation areas of the same size, and the four groups of ventilation components are respectively installed in these four installation areas.
[0043] The limiting ring 29 can limit the ventilation cylinder 30 so that the ventilation cylinder 30 can rotate on the limiting ring 29 without separating from the limiting ring 29. The limiting ring 29 is also arranged on the outside of the connecting hole. When the ventilation fan 28 extracts the air in the shed body 25, the air will pass through the connecting hole and enter the ventilation cylinder 30 limited by the limiting ring 29; a sealing mechanism is installed on the outside of the limiting ring 29 to prevent gas from leaking from the contact position between the limiting ring 29 and the limiting ring 29.
[0044] like Figure 1-Figure 3 、 Figure 10As shown, the outer side of the ventilation cylinder 30 is fixedly sleeved with a third gear 31, the lower part of the second mounting top cover 26 is fixedly connected to a motor 32, the lower output end of the motor 32 is fixedly connected to a fourth gear 33, and one side tooth of the fourth gear 33 is connected to the third gear 31, and the outer side of the ventilation cylinder 30 is fixedly connected to a connecting pipe, and the outer side of the connecting pipe is fixedly connected to a sealing rubber ring 34, and the outer side of the sealing rubber ring 34 is abutted with a sealing sleeve 35, and the upper part of the sealing sleeve 35 is fixedly connected to the second mounting top cover 26, and the lower part of the sealing sleeve 35 is fixedly connected to the shed body 25. Through the above technical solution, the sealing rubber ring 34 can seal the outer side of the connecting pipe to prevent air from leaking from the contact position between the connecting pipe and the sealing sleeve 35.
[0045] like Figure 1-Figure 3 、 Figure 10 As shown, a first ventilation pipe 36 is fixedly connected to one side of the ventilation cylinder 30, and a second ventilation pipe 37 is fixedly connected to the other side of the ventilation cylinder 30. One end of the first ventilation pipe 36 is fixedly connected to the side wall of the second mounting top cover 26, and the side wall of the second mounting top cover 26 is fixedly connected to a first filter 38 at a corresponding position where the first ventilation pipe 36 is connected. One end of the second ventilation pipe 37 is fixedly connected to the side wall of the second mounting top cover 26, and the side wall of the second mounting top cover 26 is fixedly connected to a second filter 39 at a corresponding position where the second ventilation pipe 37 is connected. Through the above technical solution, the first filter 38 and the second filter 39 can filter the air and absorb radiation pollutants in the air.
[0046] like Figures 1-10 As shown, a control panel 2 is fixedly connected to the outside of the shed corridor 1, and the control panel 2 is electrically connected to the ventilation fan 28 and the motor 32. Through the above technical solution, the control panel 2 can control the ventilation fan 28 and the motor 32.
[0047] It should be noted that when in use, the shed corridor 1 and the shed body 25 are placed on a horizontal plane, an external power supply is connected through the control panel 2, and the sealed main door 4 is opened. The sealed main door 4 drives the first ratchet 5 to rotate via the first transmission shaft, and the first ratchet 5 drives the second chain 9 to rotate via the first chain 6, the second ratchet 7, the first rotating shaft and the third ratchet 8. The second chain 9 drives the first gear 11 to rotate via the fourth ratchet 10 and the second rotating shaft. The first gear 11 drives the locking rod 13 to insert into the locking hole 15 through the first tooth plate 12. At this time, the locking plate 14 is limited by the locking rod 13, which makes the sealed secondary door 24 unable to open;
[0048] When the sealed secondary door 24 needs to be opened, the sealed main door 4 is closed first, and then the locking rod 13 is driven to reset and no longer restrict the movement of the locking plate 14. The sealed secondary door 24 is rotated to open. The sealed secondary door 24 drives the eighth ratchet 23 to rotate through the second transmission shaft. The eighth ratchet 23 drives the sixth ratchet 20 to rotate through the fourth chain 22, the seventh ratchet 21 and the third rotating shaft. The sixth ratchet 20 drives the second gear 17 to rotate through the third chain 19 and the fifth ratchet 18. The second gear 17 drives the locking plate 14 to move through the second tooth plate 16. At this time, the sealed secondary door 24 can be opened normally. At the same time, the locking hole 15 on the locking plate 14 is no longer aligned with the locking rod 13. The movement of the locking rod 13 is limited by the locking plate 14, which makes the sealed main door 4 unable to be opened.
[0049] When ventilation is needed, the ventilation fan 28 is turned on through the control panel 2. The ventilation fan 28 drives the air through the connecting hole into the ventilation cylinder 30. The air enters the connecting pipe from the ventilation cylinder 30 and drives the fourth gear 33 to rotate through the motor 32. Then the fourth gear 33 can drive the ventilation cylinder 30 to rotate. The ventilation cylinder 30 drives the connecting pipe and the sealing rubber ring 34. When the shed is in a situation where a large amount of ventilation is required, the connecting pipe and the sealing rubber ring 34 are aligned with the first ventilation pipe 36. At this time, the air flow passes through the first ventilation pipe 36 and is discharged from the first filter 38. The ventilation stroke is short and can ventilate quickly and in large quantities. When it is necessary to further strengthen radiation protection, the connecting pipe and the sealing rubber ring 34 can be aligned with the second ventilation pipe 37. At this time, the air flow needs to be discharged through the second ventilation pipe 37 and the second filter 39.
[0050] The utility model relates to the technical field of sheds and provides a radiation protection shed, which solves the problem that when the radiation protection shed is in use, when personnel or equipment enter and exit the radiation protection shed, radioactive materials or rays may leak directly from high-radiation areas to low-radiation or non-radiation areas and cause pollution. The utility model is more practical.
