Description

Technical Field

[0001] This invention relates to the field of safety warning equipment technology, and in particular to a detachable temporary safety fence. Background Technology

[0002] Temporary safety fences are widely used in production fields such as the power industry. They are mainly used to restrict the activities of workers within a specific area or to remind people of dangers, thereby eliminating or controlling safety hazards. Temporary safety fences come in various types, such as netting, fences, and warning tapes, depending on the location of use. Currently, the most common type of fence in hydropower stations is the stainless steel fence. Temporary safety fences are required for power outage maintenance of equipment in substations and power plants. Some power equipment also requires safety fences during normal operation. Temporary safety fences are also frequently used in various scenarios such as order maintenance.

[0003] Currently, the following technical drawbacks still exist in the use of temporary safety fences: 1. Since the base and posts are firmly connected by screws, it is quite troublesome to remove and install them. Under normal circumstances, they are not removed, which results in the fence taking up a very large area and being unsightly. At the same time, when moving the fence with other moving tools, the number that can be moved at one time is also very limited due to the large size and irregular shape of the fence; 2. Relying solely on guardrails and protective belts for blocking is not an ideal warning effect. Summary of the Invention

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Example 1

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10This is the first embodiment of the present invention. This embodiment provides a detachable temporary safety fence, including a fence body 100, including a chassis 101, a column 102 movably connected to the top of the chassis 101, a warning component 103 provided at the front end inside the column 102, and snap-fit ​​components 104 symmetrically arranged on the left and right sides inside the chassis 101. A pressing mechanism 105 is provided below the two sets of snap-fit ​​components 104.

[0037] An installation groove 101a is provided at the center of the top of the chassis 101. When the column 102 is inserted into the installation groove 101a, the snap-fit ​​component 104 can snap-fit ​​and fix the column 102, thereby completing the assembly of the column 102 and the chassis 101. By operating the pressing mechanism 105, the staff can easily release the snap-fit ​​component 104 from the column 102, thereby realizing the quick disassembly of the column 102 and the chassis 101. This ensures that the column 102 and the chassis 101 can be placed separately during storage, thus achieving neat placement and saving space. When someone approaches or crosses the fence, the warning component 103 is set at the front end of the column 102 to remind relevant personnel and improve the warning effect of the fence.

[0038] Preferably, a winding sleeve 102b is rotatably connected to the center of the top of the column 102. A protective strip 102c is wrapped around the outer surface of the winding shaft at the center of the winding sleeve 102b. An insert block 102d is fixedly connected to the right end of the protective strip 102c. A slot 102e matching the insert block 102d is provided on the left side of the upper end of the column 102. The insert block 102d and the slot 102e are existing technologies and will not be described in detail. The winding sleeve 102b is used to wind up and store the protective strip 102c. The insert block 102d and the slot 102e are used to connect between every two fence bodies 100.

[0039] When a safety fence needs to be assembled, the workers place two independent fence bodies 100 on the same horizontal line, with a distance between them (this distance can be determined according to the actual length of the protective strip 102c). The side of one fence body 100 with the insert 102d is placed opposite the side of the other fence body 100 with the slot 102e. Then, the workers remove the insert 102d of one fence body 100 and insert it into the slot of the other fence body 100. The two fence bodies 100 and the protective strip 102c in the middle can then form a safety fence.

[0040] Example 2

[0041] Reference Figures 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0042] Specifically, the warning component 103 includes a threaded rod 103a rotatably connected to the center of the column 102. A lifting ring 103b is threadedly connected to the outer surface of the threaded rod 103a. A warning sign 103d is fixedly connected to the front end of the lifting ring 103b via a fixing rod 103c. A driven conical tooth 103e is fixedly connected to the bottom end of the threaded rod 103a. An active conical tooth 103f is meshed with the right end of the driven conical tooth 103e. A rotating rod 103g is fixedly connected to the right end of the active conical tooth 103f. The right end of the rotating rod 103g penetrates the inner wall of the column 102 and extends to its outside where a knob 103h is fixedly connected.

[0043] Rotating knob 103h causes rotating rod 103g to rotate, which in turn causes active bevel gear 103f to rotate. Active bevel gear 103f causes driven bevel gear 103e to rotate, which in turn causes threaded rod 103a to rotate. Consequently, lifting ring 103b, which is threaded to threaded rod 103a, can move vertically. Lifting ring 103b can move warning sign 103d at the front end of column 102 up and down via fixed rod 103c. When warning sign 103d moves to its highest position, its warning effect is maximized.

[0044] Example 3

[0045] Reference Figures 1-11 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0046] Specifically, the two sets of snap-fit ​​components 104 include snap rings 104a symmetrically arranged on the left and right sides of the mounting groove 101a. A connecting plate 104b is installed on the opposite side of each of the two snap rings 104a. A first limiting plate 104c is installed on the opposite side of each of the two connecting plates 104b. A first telescopic spring 104d is fixedly connected to the opposite side of each of the two first limiting plates 104c. A connecting rod 104e is symmetrically installed at the bottom end of each of the two connecting plates 104b. An arc-shaped block 104f is symmetrically installed on the opposite side of each of the two connecting rods 104e.

[0047] The outer surface of the bottom end of the column 102 is provided with annular grooves 102a that match the two retaining rings 104a. The bottom of the column 102, located below the annular grooves 102a, is truncated cone-shaped. Figure 9As shown, since the bottom of the column 102 is a frustum shape with a narrow bottom and a wide top, when the column 102 is inserted downward into the mounting groove 101a, the two retaining rings 104a can be pressed towards the left and right sides inside the chassis 101. The retaining rings 104a can compress the first telescopic spring 104d through the connecting plate 104b and the first limiting plate 104c. When the bottom surface of the column 102 contacts the inner bottom wall of the mounting groove 101a, the two retaining rings 104a can be parallel to the annular groove 102a. At this time, under the action of the rebound force of the two first telescopic springs 104d, the two retaining rings 104a can be bounced back to the initial position, so that the inner sidewalls of the two retaining rings 104a can be tightly attached to the annular groove 102a, thereby locking and fixing the column 102 and realizing the splicing of the column 102 and the chassis 101.

[0048] Furthermore, the pressing mechanism 105 includes a pressing cone 105a disposed at the front end of the middle of the two arc-shaped blocks 104f. A pressing rod 105b is fixedly connected to the front end of the pressing cone 105a. A second limiting plate 105c is installed on the outer surface of the pressing rod 105b. A second telescopic spring 105d is fixedly connected to the rear end of the second limiting plate 105c. The second telescopic spring 105d is sleeved on the outer surface of the pressing rod 105b. A pressing component 105e is disposed at the front end of the pressing rod 105b.

[0049] When it is necessary to separate the column 102 from the chassis 101, the operator presses the pressing component 105e. The pressing component 105e can push the pressing rod 105b and the pressing cone 105a towards the center of the chassis 101. Since the pressing cone 105a is a frustum-shaped cone with a narrower rear end and a wider front end, and the narrower rear end of the pressing cone 105a is located between the two arc-shaped blocks 104f, when the pressing cone 105a moves backward, it can press the two arc-shaped blocks 104f to move to the left and right sides of the chassis 101. The two arc-shaped blocks 104f can drive the two connecting plates 104b and the retaining rings 104a to move to the left and right sides of the chassis 101 through the two connecting rods 104e. This releases the two retaining rings 104a from the column 102. At this time, the operator can pull out the column 102 and complete the separation of the column 102 from the chassis 101.

[0050] like Figure 3 As shown, when the pressing rod 105b moves into the chassis 101, it can drive the second limiting plate 105c to move backward. The second limiting plate 105c can squeeze the second telescopic spring 105d. When the operator releases the pressing component 105e, under the elastic force of the second telescopic spring 105d, the pressing cone 105a, the pressing rod 105b and the pressing component 105e can spring back to the initial position, which provides convenience for subsequent use.

[0051] Furthermore, the pressing assembly 105e includes a third limiting plate 105e-1 installed at the front end of the pressing rod 105b. A third telescopic spring 105e-2 is fixedly connected to the front end of the third limiting plate 105e-1. A pressing knob 105e-3 is sleeved on the front end of the pressing rod 105b. The third limiting plate 105e-1 and the third telescopic spring 105e-2 are both located inside the pressing knob 105e-3. The front end of the third telescopic spring 105e-2 is connected to the inner wall of the pressing knob 105e-3. L-shaped blocks 105e-4 are symmetrically installed on the left and right sides of the rear end of the pressing knob 105e-3.

[0052] A moving groove 105b-1 is provided at the center of the front end of the extrusion rod 105b. The rear ends of the two L-shaped blocks 105e-4 are both set in the moving groove 105b-1. Arc-shaped slots 105b-2 are obliquely symmetrically provided at the lower left and upper right of the front end of the moving groove 105b-1 (e.g., Figure 7 and Figure 9 (as shown);

[0053] When an outsider accidentally kicks the pressing knob 105e-3, causing it to move along the outer surface of the pressing rod 105b towards the inside of the chassis 101, the pressing knob 105e-3 can compress the third telescopic spring 105e-2 to retract and drive the two L-shaped blocks 105e-4 to move backward along the moving groove 105b-1, but it cannot push the pressing rod 105b to move. This prevents the pressing cone 105a from moving backward, thereby preventing the two retaining rings 104a from releasing the locking and fixing of the column 102, ensuring the stability of the connection between the column 102 and the chassis 101.

[0054] When it is necessary to release the fixing relationship between the column 102 and the chassis 101, the operator first rotates the pressing knob 105e-3 counterclockwise. The pressing knob 105e-3 can drive the two L-shaped blocks 105e-4 to rotate into the two arc-shaped slots 105b-2 respectively, so that the two L-shaped blocks 105e-4 abut against the pressing rod 105b. At this time, the operator presses the pressing knob 105e-3 again, and the pressing knob 105e-3 can then pass through the two L-shaped blocks 105e-2. -4 drives the compression rod 105b to move backward, and the compression rod 105b drives the compression cone 105a to move towards the center of the chassis 101. The compression cone 105a compresses the two arc-shaped blocks 104f to move to the left and right sides of the chassis 101. The two arc-shaped blocks 104f can drive the two connecting plates 104b and the retaining rings 104a to move to the left and right sides of the chassis 101 through the two connecting rods 104e, thereby releasing the two retaining rings 104a from the column 102.

[0055] Preferably, a cavity 101b is provided inside the chassis 101 and below the mounting groove 101a. The two arc-shaped blocks 104f and the compression cone 105a are all located in the cavity 101b. The cavity and 101b provide space for the movement of the arc-shaped blocks 104f and the compression cone 105a. The front end of the pressing knob 105e-3 penetrates the inner front wall of the chassis 101 and extends to its outside, making it convenient for operators to use.

[0056] 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.
