Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0021] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention, which provides a safety fence for the maintenance of deep pits in dams. Specifically, it includes a fence post mechanism 100, which includes a base 101 and a fence main body assembly 102 fixed on the upper part of the base 101; and a connecting mechanism 200, which includes a rotating post assembly 201 rotatably disposed on the side wall of the fence main body assembly 102 and a fixing assembly 202 disposed below the rotating post assembly 201.

[0022] It should be noted that when the cement surface near the dam pit is relatively smooth, the base 101 can be a suction cup base to adhere to the cement surface; if the cement surface near the dam pit is not smooth, the base 101 needs to have a large counterweight to stably support the main component 102 of the fence.

[0023] Furthermore, the main component of the fence 102 includes fence posts 102a, with symmetrical rotating grooves K-1 on the side walls of the fence posts 102a; the main component of the fence 102 also includes a rotating seat 102b fixed to the upper section of the rotating groove K-1, and a locking seat 102c fixed below the rotating seat 102b in the rotating groove K-1; there are two locking seats 102c, symmetrically arranged below the rotating seat 102b.

[0024] Preferably, the fence post 102a is further provided with a first pressing post hole K-2 located on the side wall of the rotating post groove K-1, a pressing block hole K-3 connected to the side wall of the first pressing post hole K-2 and located at the lower part of the first pressing post hole K-2, and a second pressing post hole K-4 connected to the lower section of the side wall of the pressing block hole K-3; the rotating seat 102b is provided with a through hole K-5 coaxially connected to the first pressing post hole K-2, a ball cavity K-6 connected to one end of the through hole K-5, and a pressing groove K-7 opened at the lower part of the ball cavity K-6, the top of the pressing groove K-7 being located below the center of the ball cavity K-6; ​​the lock seat 102c is located below the second pressing post hole K-4, and a sliding groove K-8 is opened in the lock seat 102c.

[0025] In this embodiment, after the operator installs the base 101 on the cement surface near the deep pit of the dam, they can be connected to each other through the rotating column assembly 201. While the rotating column assemblies 201 are connected to each other, the fixing component 202 can help fix the rotating column assembly 201.

[0026] Example 2 Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] Specifically, the rotating column assembly 201 includes a rotating column member 201a rotatably disposed in the ball cavity K-6, and a pressure column member 201b slidably disposed in the rotating column member 201a; the rotating column member 201a includes a rotating ball 201a-1 rotatably disposed in the ball cavity K-6, and a rotating column 201a-2 fixed on the outer wall of the rotating ball 201a-1; the rotating column 201a-2 has a pressure column hole K-9 that passes through the axis of the rotating column 201a-2 and the center of the rotating ball 201a-1, and a limiting cavity K-10 located in the middle section of the pressure column hole K-9.

[0028] It should be noted that, as in the 201a-2 rotating column... Figure 5As shown, there are two types of rotating posts 201a-2: one with threads on the outer wall of the end and the other with threads on the inner wall of the end. These two types of rotating posts 201a-2 are grouped together, and a group of such rotating posts 201a-2 is symmetrically arranged on a fence main component 102.

[0029] Furthermore, the pressure column component 201b includes a first pressure column 201b-1 slidably disposed in the pressure column hole K-9, a limiting plate 201b-2 fixed in the middle section of the first pressure column 201b-1 and slidably disposed in the limiting cavity K-10, and a pressure column spring 201b-3 whose two ends contact the limiting plate 201b-2 and the end of the limiting cavity K-10.

[0030] It should be noted that after the first pressure column 201b-1 is compressed, it will slide towards the end of the rotating ball 201a-1 in the pressure column hole K-9 and partially extend out of the pressure column hole K-9 towards the end of the rotating ball 201a-1. When the first pressure column 201b-1 is not compressed, the end of the first pressure column 201b-1 will not slide out of the pressure column hole K-9 towards the end of the rotating ball 201a-1.

[0031] Furthermore, the fixing component 202 includes a pressure block 202a slidably disposed in the pressure block hole K-3, and a stop block 202b slidably disposed on the upper part of the slide groove K-8; the two ends of the pressure block 202a are chamfered; the stop block 202b includes a stop block 202b-1 slidably disposed on the upper part of the slide groove K-8, a second pressure column 202b-2 slidably disposed in the second pressure column hole K-4 and whose end contacts the side wall of the pressure block hole K-3, and a stop block tension spring 202b-3 whose two ends respectively contact the side wall of the stop block 202b-1 and the side wall of the rotating column groove K-1.

[0032] Preferably, the side wall of the stop block 202b-1 contacts the side wall of the first pressure column 201b-1, and the stop block 202b-1 has a magnetic attraction to the first pressure column 201b-1.

[0033] It should be noted that the stop spring 202b-3 provides tension to the stop block 202b-1, so that the stop block 202b-1 is close to the side wall of the rotating column groove K-1 without any other external force. The stop block 202b-1 close to the side wall of the rotating column groove K-1 can limit the rotating column 201a-2 in the rotating column groove K-1 without any other external force through magnetic attraction.

[0034] In this embodiment, when the operator needs to install the safety fence, the rotating posts 201a-2 on the safety fence used for the maintenance of the deep pit of the dam need to be rotated to be vertical and threaded together. During the threading process of the rotating posts 201a-2, the first pressure posts 201b-1 of the two rotating posts 201a-2 will press against each other. During the pressing process, the first pressure post 201b-1 will slide from the pressure post hole K-9 into the through hole K-5, and then extend into the first pressure post hole K-2; in the first pressure post 201a-2 During the process of 01b-1 penetrating deeper into the first pressure column hole K-2, the end of the first pressure column 201b-1 will press the upper chamfer of the pressure block 202a. This will cause the lower chamfer of the pressure block 202a to press the second pressure column 202b-2, causing the stop block 202b-1 to slide from the end of the slide groove K-8 near the second pressure column hole K-4 to the end away from the second pressure column hole K-4. At this time, the top of the stop block 202b-1 slides into the pressure groove K-7, which can provide auxiliary support for the side wall of the rotating column 201a-2.

[0035] It should be noted that when the rotating column 201a-2 is housed in the rotating column groove K-1, the stop block 202b-1 can magnetically attract the side wall of the rotating column 201a-2, so that the rotating column 201a-2 is limited in the rotating column groove K-1 without any other external force.

[0036] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
