Detailed implementation manners

[0030] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of the present invention, and the present invention can also be implemented in many other embodiments different from those described herein. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0033] Please refer to Figure 1-6 , the present invention provides a nuclear power plant tension fence that facilitates the disassembly and assembly of the pull rope. This tension fence is mainly applied to nuclear power plants to protect the safety of nuclear power plants. In other embodiments, this tension fence can also be applied to other places, such as airports, shopping malls, or hospitals.

[0034] The nuclear power plant tension fence includes a mounting member 1 and a pull rope 3. A middle rod 2 is rotatably connected to the top of the mounting member 1. A plurality of first fixing holes 6 are formed in the outer wall of the mounting member 1. The mounting member 1 adjusts the angle of the middle rod 2 through the first fixing holes 6. Specifically, a plurality of second fixing holes (not shown in the figure) are formed at the bottom of the middle rod 2. The plurality of first fixing holes 6 and the plurality of second fixing holes are all arranged along the rotation direction of the middle rod 2. When the middle rod 2 rotates relative to the mounting member 1, there can be a situation where one first fixing hole 6 corresponds to one second fixing hole at different included angles. At this time, a screw can be passed through the first fixing hole 6 and the second fixing hole to fix the middle rod 2 in the current position. When it is necessary to change the angle of the middle rod 2, the screw can be first withdrawn, then the middle rod 2 can be rotated to a new position, and the screw can be inserted again. A mounting hole 7 is formed at the bottom of the mounting member 1. The mounting member 1 can use screws to pass through the mounting hole 7 to fixedly install the mounting member 1. The pull rope 3 is installed on the middle rod 2 through a mounting mechanism 4.

[0035] The installation mechanism 4 includes a mounting base 401, a first spring 404, a linkage structure, a first switch 408, a second switch 409, and two clamping members. The mounting base 401 is provided on the intermediate rod 2. The two clamping members are slidably connected to the mounting base 401. The two ends of the first spring 404 are connected to the two clamping members. The first switch 408 is connected to the two clamping members through the linkage structure. The first switch 408 and the second switch 409 are respectively slidably connected to the mounting base 401 along different directions. The second switch 409 can lock or unlock the first switch 408 when sliding. When the second switch 409 unlocks the first switch 408, the first switch 408 can slide to drive the two clamping members to approach each other through the linkage structure to clamp the pull rope 3, and at the same time drive the first spring 404 to accumulate elastic force. The first spring 404 can release the elastic force to drive the two clamping members to separate and unlock the pull rope 3. Therefore, when it is necessary to disassemble and assemble the pull rope 3, only need to first slide the second switch 409 away from the first switch 408, the first spring 404 releases the elastic force to drive the two clamping members to separate and unlock the pull rope 3, and the staff can take out the pull rope 3, without spending a lot of time pulling out the pull rope 3, saving time and being beneficial to improving the maintenance efficiency.

[0036] The structures of the two clamping members are the same, and both include an integrally formed movable plate 403 and a connecting block 405. Among them, the movable plate 403 is located inside the mounting base 401, and the connecting block 405 extends out of the mounting base 401 to facilitate clamping the pull rope 3.

[0037] The installation mechanism 4 includes a mounting base 401. The mounting base 401 is provided on one side of the intermediate rod 2. An activity groove 402 is opened inside the mounting base 401. The inner walls of the activity groove 402 are symmetrically and slidably connected with movable plates 403. A first spring 404 is connected between the two movable plates 403. The first spring 404 is used to automatically separate the two movable plates 403. A connecting block 405 is fixedly connected to the outer wall of the first spring 404. The connecting block 405 extends out of the mounting base 401. The two connecting blocks 405 are in contact and combined to form a hole groove for the pull rope 3 to pass through. The position of the mounting base 401 is adjusted by an adjusting mechanism 5.

[0038] The mounting mechanism 4 further includes a push plate 406. The push plate 406 is slidably connected to the inside of the mounting base 401 and is located on one side of the movable plate 403. A spur gear 407 is rotatably connected to the top of the push plate 406 inside the mounting base 401. A first switch 408 is slidably connected to the top of the spur gear 407 inside the mounting base 401. The movement of the first switch 408 drives the push plate 406 to move through the spur gear 407. The movement of the push plate 406 drives the two movable plates 403 to move closer to each other. A second switch 409 is slidably connected to the top of the first switch 408 inside the mounting base 401. One end of the second switch 409 is in contact with the first switch 408. A second spring 410 is connected between the second switch 409 and the mounting base 401. The second switch 409 is engaged with the first switch 408 under the elastic force of the second spring 410.

[0039] In this embodiment, the two connecting blocks 405 are in contact and combined to form a hole groove for the pull rope 3 to pass through. When installing the pull rope 3, the pull rope 3 is moved between the two connecting blocks 405. After completion, the first switch 408 is pushed into the mounting base 401 to move. At this time, the second switch 409 is engaged with the first switch 408 under the elastic force of the second spring 410 to prevent the first switch 408 from moving outwards. The movement of the first switch 408 drives the spur gear 407 to rotate. The rotation of the spur gear 407 drives the push plate 406 to move. The movement of the push plate 406 pushes the two movable plates 403 to move closer to each other, squeezing the first spring 404. The movement of the movable plate 403 drives the two connecting blocks 405 to move closer to each other. The two connecting blocks 405 are in contact to complete the installation of the pull rope 3.

[0040] When removing the pull rope 3, the second switch 409 is pushed to move. The second switch 409 is separated from the first switch 408, canceling the engagement with the first switch 408. At this time, the two movable plates 403 move away from each other under the elastic force of the first spring 404, driving the two connecting blocks 405 to move away from each other and loosening the pull rope 3, so as to remove the pull rope 3.

[0041] In a further preferred embodiment of the present invention, as Figures 2-5 shown, the adjusting mechanism 5 includes a moving seat 501. The moving seat 501 is fixedly connected to one end of the mounting base 401 away from the connecting block 405. A displacement groove 502 is provided on the outer wall of the moving seat 501. The intermediate rod 2 slides in the inner cavity of the displacement groove 502 for adjusting the position of the mounting base 401. A limiting groove 503 is provided on the outer wall of the intermediate rod 2. A limiting block 504 extending into the inner cavity of the displacement groove 502 is slidably connected inside the moving seat 501.

[0042] A limiting spring 505 is connected between the limiting block 504 and the moving seat 501. The limiting block 504 is displaced into the limiting groove 503 under the elastic force of the limiting spring 505 to limit the moving seat 501. A positioning groove 506 is formed at the top end of the limiting block 504. A positioning block 507 is slidably connected above the positioning groove 506 inside the moving seat 501. The movement of the positioning block 507 into the positioning groove 506 is used to fix the limiting block 504. A lead screw 508 extending into the inside of the positioning block 507 is rotatably connected inside the moving seat 501. The rotation of the lead screw 508 is used to drive the positioning block 507 to move. A rotating block 509 is fixedly connected to the top end of the lead screw 508 at the top end of the moving seat 501.

[0043] In this embodiment, when adjusting the position of the mounting seat 401, at this time, the positioning block 507 does not enter the positioning groove 506. Push the moving seat 501 to slide on the outer wall of the middle rod 2. After adjusting to a suitable height, the limiting block 504 is displaced into the limiting groove 503 under the elastic force of the limiting spring 505 to limit the moving seat 501. After completion, rotate the rotating block 509. The rotation of the rotating block 509 drives the lead screw 508 to rotate. The rotation of the lead screw 508 drives the positioning block 507 to move. The positioning block 507 moves into the positioning groove 506, thereby fixing the limiting block 504, so that the limiting block 504 cannot be displaced out of the limiting groove 503, thereby fixing the moving seat 501, and further adjusting the position of the mounting seat 401, which is convenient for quickly adjusting the gap of the pull rope 3 by adjusting the position of the mounting seat 401.

[0044] In a further preferred embodiment of the present invention, as Figure 4 and Figure 6 shown, a ratchet tooth is provided at the top end of the first switch 408, and the ratchet tooth is engaged with the bottom end of the second switch 409.

[0045] In this embodiment, push the first switch 408 into the mounting seat 401 to move. At this time, the second switch 409 is engaged with the first switch 408 under the elastic force of the second spring 410 to prevent the first switch 408 from moving outwards.

[0046] In a further preferred embodiment of the present invention, as Figure 4 and Figure 6 shown, tooth grooves are provided at the bottom end of the first switch 408 and the top end of the push plate 406, and the tooth grooves are engaged with the spur gear 407. Oblique grooves 8 are symmetrically formed on the outer wall of the push plate 406. The oblique grooves 8 are in contact with the movable plate 403, and the outer wall of the movable plate 403 is attached to the inner wall of the movable groove 402.

[0047] In this embodiment, the movement of the first switch 408 drives the spur gear 407 to rotate. The rotation of the spur gear 407 drives the push plate 406 to move. The movement of the push plate 406 pushes the two movable plates 403 to move closer to each other, squeezing the first spring 404. The movement of the movable plate 403 drives the two connecting blocks 405 to move closer to each other, and the two connecting blocks 405 come into contact with each other.

[0048] In a further preferred embodiment of the present invention, as Figure 3 and Figure 4 shown, the outer wall of the middle rod 2 fits against the inner wall of the displacement groove 502. The inner wall of the displacement groove 502 is square in shape. The inner wall of the limiting groove 503 fits against the outer wall of the limiting block 504. One end of the limiting block 504 located inside the displacement groove 502 is provided with a semi-circular surface.

[0049] In this embodiment, the movable seat 501 is pushed to slide on the outer wall of the middle rod 2. After adjusting to a suitable height, the limiting block 504 moves into the limiting groove 503 under the elastic force of the limiting spring 505 to limit the movable seat 501.

[0050] In a further preferred embodiment of the present invention, as Figure 4 and Figure 5 shown, a threaded hole is opened at the top of the positioning block 507. The threaded hole matches the lead screw 508. The inner wall of the positioning groove 506 fits against the outer wall of the positioning block 507.

[0051] In this embodiment, the rotating block 509 is rotated. The rotation of the rotating block 509 drives the lead screw 508 to rotate. The rotation of the lead screw 508 drives the positioning block 507 to move. The positioning block 507 moves into the positioning groove 506, thereby fixing the limiting block 504 so that the limiting block 504 cannot be displaced out of the limiting groove 503, thereby fixing the movable seat 501, and further adjusting the position of the mounting seat 401.
