[0027] The following is combined with Figure 1-8 While describing the preferred embodiments of the present invention, it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Reference Figure 1 、 Figure 2 and Figure 3 The utility model discloses a nuclear filter mounting rack comprising a mounting rack 1, a low-efficiency filter 2, a high-efficiency filter 3, and reserved ventilation openings 4 evenly arranged on the mounting rack 1. Adjustment bolts 9 are fixedly connected to both sides of the upper and lower surfaces of the mounting rack 1. Support legs 10 are threadedly connected to both sides of the adjustment bolts 9 away from the mounting rack 1.

[0029] When in use, first install the installation rack 1 on the side of the outer wall of the wall with a pre-set concrete wall hole. The installation method can adopt various on-site installation methods such as expansion bolt type (expansion bolt), embedded guide rail type (pressing plate), embedded channel steel type (fastener), etc. These rack installation sealing methods are simple and convenient in structure and easy to construct. At the same time, a rubber sealing strip is used to seal between the installation rack 1 and the concrete wall hole to improve the airtightness between the two;

[0030] After the mounting rack 1 is installed on the wall with a concrete wall hole, the distance between the supporting legs 10 and the mounting rack 1 is adjusted by twisting the supporting legs 10 until the supporting legs 10 are in contact with the ground and the ceiling, thereby preliminarily ensuring the stability of the mounting rack 1.

[0031] Reference Figure 1 、 Figure 3 and Figure 4 , a first fastening assembly 5 for mounting the low-efficiency filter 2 on the mounting rack 1 and a second fastening assembly 6 for mounting the high-efficiency filter 3 on the mounting rack 1 are provided on one side of the outer side wall of the mounting rack 1;

[0032] Reference Figure 1 、 Figure 3 and Figure 5 The low-efficiency filter 2 is detachably mounted on one side of the outer wall of the mounting frame 1 near the reserved ventilation opening 4 through a first fastening assembly 5. The first fastening assembly 5 includes two support pins 51 fixedly connected to one side of the outer wall of the mounting frame 1 and located below the reserved ventilation opening 4, and four first fastening bolts 52 fixedly connected to the outer wall of the mounting frame 1 and symmetrically arranged above and below the reserved ventilation opening 4. A butterfly nut 53 is threadedly connected to the first fastening bolt 52. When the low-efficiency filter 2 needs to be installed, the butterfly nut 53 is first rotated to move the butterfly nut 53 away from the side of the mounting frame 1, and then the low-efficiency filter 2 is placed on the two supporting pins 51 and the low-efficiency filter 2 is initially supported by the supporting pins 51, and then the butterfly nut 53 is rotated to move the butterfly nut 53 toward the side close to the low-efficiency filter 2, thereby clamping the low-efficiency filter 2 between the butterfly nut 53 and the outer wall of the mounting frame 1;

[0033] Since the low-efficiency filter 2 is small in size and weight, when disassembling the low-efficiency filter 2, the butterfly nut 53 can be rotated first to move the butterfly nut 53 away from the installation rack 1, so as to stop the butterfly nut 53 from clamping the low-efficiency filter 2. Then, the staff can directly remove the low-efficiency filter 2 placed on the two support pins 51 to complete the disassembly.

[0034] Reference Figure 3 、 Figure 4 and Figure 6 The high-efficiency filter 3 is detachably mounted on one side of the outer wall of the mounting rack 1 near the reserved ventilation opening 4 through the second fastening assembly 6. The second fastening assembly 6 includes a support plate 61 fixedly mounted on the side of the outer wall of the mounting rack 1 away from the first fastening assembly 5 and located below the reserved ventilation opening 4, and a connecting rod 62 fixedly connected to the side of the outer wall of the mounting rack 1 near the support plate 61 and symmetrically arranged above and below the reserved ventilation opening 4.

[0035] Reference Figure 3 、 Figure 6 and Figure 7The end of the connecting rod 62 away from the mounting frame 1 is rotatably connected to the rotating rod 63, and the outside of the rotating rod 63 is slidably connected to the clamping plate 64. The clamping plate 64 is a rectangular plate, and the distance from one end of the clamping plate 64 to the axis of the rotating rod 63 is less than the radius of the connecting rod 62, and the distance from the other end of the clamping plate 64 to the axis of the rotating rod 63 is greater than the radius of the connecting rod 62. The outer wall of the rotating rod 63 is fixedly connected to a connecting block 68 at one end near the connecting rod 62, and a spring 69 is fixedly connected to the side of the connecting block 68 near the clamping plate 64. The end of the spring 69 away from the connecting block 68 is fixedly connected to the clamping plate 64, and the end of the rotating rod 63 away from the mounting frame 1 is fixedly connected to a connecting sleeve 65, and one side of the outer wall of the connecting sleeve 65 is rotatably connected to an eccentric top block 66, and one side of the outer wall of the eccentric top block 66 is fixedly connected to a rotating handle 67.

[0036] Reference Figure 3 and Figure 8 When the high efficiency filter 3 needs to be installed, the handle 67 is first turned to drive the rotating rod 63 to rotate until the end of the clamping plate 64 away from the rotating rod 63 is away from the reserved ventilation opening 4, and then the high efficiency filter 3 is placed on the supporting plate 61, thereby minimizing the influence of the clamping plate 64 on the placement of the high efficiency filter 3. When the high efficiency filter 3 is placed on the supporting plate 61, the handle 67 is turned again to drive the rotating rod 63 to rotate until the end of the clamping plate 64 away from the rotating rod 63 is toward the reserved ventilation opening 4, thereby minimizing the fall of the high efficiency filter 3. Then, the handle 67 is turned to drive the eccentric top block 66 to rotate until the end of the eccentric top block 66 away from the rotating shaft abuts against the clamping plate 64, and drives the clamping plate 64 to move to the side away from the connecting sleeve 65, the spring 69 is compressed, and the high efficiency filter 3 is clamped between the clamping plate 64 and the outer wall of the installation rack 1 through the clamping plate 64;

[0037] The outer wall of the mounting rack 1 is fixedly connected to a protective shell 7 around the second fastening component 6, and ridges 8 are provided on all sides of the outer wall of the protective shell 7. Due to the large size and weight of the high-efficiency filter 3, when it is necessary to disassemble the high-efficiency filter 3, the opening of the receiving bag made of radiation-proof material is first sleeved on the outside of the protective shell 7, and then the rope is wrapped between the two adjacent ridges 8 to fix the receiving bag to the protective shell 7, and then the eccentric top block 66 is driven to rotate through the receiving bag by rotating the handle 67 until the end of the eccentric top block away from the rotating shaft is away from the clamping plate 64, and then the spring 69 is reset, driving the clamping plate 64 to move to the side close to the connecting sleeve 65, stopping the clamping of the high-efficiency filter 3, and then the rotating rod 63 is driven to rotate by rotating the handle 67 until the end of the clamping plate 64 away from the rotating rod is away from the reserved ventilation port 4. At this time, the staff pushes the high-efficiency filter 3 from the side of the mounting rack 1 away from the protective shell 7, so that the high-efficiency filter 3 falls into the receiving bag, and the disassembly is completed.

[0038] The working principle of this utility model is:

[0039] When in use, first install the installation rack 1 on the side of the outer wall of the wall with a pre-set concrete wall hole. The installation method can adopt various on-site installation methods such as expansion bolt type (expansion bolt), embedded guide rail type (pressing plate), embedded channel steel type (fastener), etc. These rack installation sealing methods are simple and convenient in structure and easy to construct. At the same time, a rubber sealing strip is used to seal between the installation rack 1 and the concrete wall hole to improve the airtightness between the two;

[0040] After the mounting rack 1 is installed on the wall with a concrete wall hole, the distance between the supporting legs 10 and the mounting rack 1 is adjusted by twisting the supporting legs 10 until the supporting legs 10 are in contact with the ground and the ceiling, thereby preliminarily ensuring the stability of the mounting rack 1.

[0041] When the low-efficiency filter 2 needs to be installed, the butterfly nut 53 is first rotated to move the butterfly nut 53 away from the installation bracket 1, and then the low-efficiency filter 2 is placed on the two support pins 51 and the support pins 51 are used to initially support the low-efficiency filter 2. The butterfly nut 53 is then rotated to move the butterfly nut 53 toward the side close to the low-efficiency filter 2, thereby clamping the low-efficiency filter 2 between the butterfly nut 53 and the outer wall of the installation bracket 1;

[0042] When the low-efficiency filter 2 is to be disassembled, the butterfly nut 53 is first rotated to move the butterfly nut 53 away from the mounting rack 1, and the butterfly nut 53 stops clamping the low-efficiency filter 2. Then the staff directly removes the low-efficiency filter 2 placed on the two support pins 51 to complete the disassembly.

[0043] When the high efficiency filter 3 needs to be installed, the handle 67 is first turned to drive the rotating rod 63 to rotate until the longer end of the clamping plate 64 is away from the reserved ventilation opening 4, and then the high efficiency filter 3 is placed on the support plate 61, so as to avoid the clamping plate 64 affecting the placement of the high efficiency filter 3 as much as possible. When the high efficiency filter 3 is placed on the support plate 61, the handle 67 is turned again to drive the rotating rod 63 to rotate until the longer end of the clamping plate 64 is facing the reserved ventilation opening 4, so as to avoid the high efficiency filter 3 from falling off as much as possible, and then the handle 67 is turned to drive the eccentric top block 66 to rotate until the end of the eccentric top block 66 away from the rotating shaft abuts the clamping plate 64, and drives the clamping plate 64 to move to the side away from the connecting sleeve 65, the spring 69 is compressed, and the high efficiency filter 3 is clamped between the clamping plate 64 and the outer wall of the installation rack 1 through the clamping plate 64;

[0044] When the high-efficiency filter 3 needs to be disassembled, the opening of the receiving bag made of radiation-proof material is first sleeved on the outside of the protective shell 7, and then the receiving bag is fixed to the protective shell 7 by wrapping the rope around the two adjacent protrusions 8. Then, the eccentric top block 66 is driven to rotate through the receiving bag by rotating the handle 67 until the end of the eccentric top block away from the rotating shaft is away from the clamping plate 64, and then the spring 69 is reset, driving the clamping plate 64 to move toward the side close to the connecting sleeve 65, stopping the clamping of the high-efficiency filter 3, and then the handle 67 is rotated to drive the rotating rod 63 to rotate to the longer end of the clamping plate 64 away from the reserved ventilation port 4. At this time, the staff pushes the high-efficiency filter 3 from the side of the installation rack 1 away from the protective shell 7, so that the high-efficiency filter 3 falls into the receiving bag, completing the disassembly.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
