Description

Technical Field

[0001] This utility model relates to the field of fence technology, specifically to a safety protection fence. Background Technology

[0002] Inspection gates (also known as maintenance gates) are metal gates installed near the turbine inlet of pressure pipelines or water diversion tunnels. Their main function is to cut off the water flow during unit maintenance, so as to completely isolate the unit from the upstream water source.

[0003] The door groove, serving as the installation base for the maintenance door, is a guide rail structure set along a vertical or inclined direction to guide the maintenance door to operate smoothly during opening and closing.

[0004] To protect the internal structure of the doorway and prevent debris from falling in, a cover plate (such as a steel plate or concrete cover plate) is usually placed on top of the doorway. The cover plate also facilitates passage on the ground.

[0005] During unit maintenance work, the maintenance door needs to be lowered and some or all of the cover plates need to be removed. After the cover plates are removed, the work area will be exposed to pits, posing a risk of personnel falling in. Therefore, it is necessary to set up fences for isolation and protection.

[0006] However, existing fencing structures are often difficult to adjust flexibly according to the on-site operation range and protection needs, and cannot effectively adapt to the layout requirements of safety areas of different shapes. Utility Model Content

[0007] The purpose of this utility model is to provide a safety protection fence that solves the problem that existing fence structures are often difficult to adjust flexibly according to the on-site operation range and protection needs, and cannot effectively adapt to the layout requirements of safety areas of different shapes.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A safety fence includes a fence body, connecting posts, and a base. The connecting posts are located at the bottom of the fence body, and there are two connecting posts, which are distributed at both ends of the fence body. The base is located below the fence body and has two connecting holes, which are arranged side by side. The two connecting holes on the base are rotatably connected to either of the two connecting posts on the fence body.

[0010] A further technical solution is that the safety fence also includes a first locking member; the first locking member passes through the wall of the connecting hole and is used to abut against the connecting post.

[0011] A further technical solution is that the safety fence also includes a guide plate and a guide rod; the guide plate is disposed on the base, and a guide hole is provided on the guide plate; the guide rod passes through the guide hole.

[0012] A further technical solution is that the safety fence also includes a second locking member; the second locking member passes through the guide plate and abuts against the guide rod.

[0013] A further technical solution is that the safety fence also includes a support post; the support post passes through the base and extends from the top of the base to the bottom of the base.

[0014] A further technical solution is: the base has a support hole that extends from the top surface of the base to the bottom surface of the base; the support column passes through the support hole; the safety fence also includes a third locking member; the third locking member passes through the base and abuts against the support column.

[0015] A further technical solution is: the number of fence bodies is set to N, and the N fence bodies are connected end to end in sequence; where N≥3, and N is an integer.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The fence body is rotatably connected to the connecting holes on the base via connecting posts, allowing users to adjust the angle between adjacent fence bodies as needed. This aims to enable users to flexibly adjust the fence body according to the on-site work area and protection requirements, adapting to the layout requirements of safety zones of different shapes.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] Example 1: This example provides a safety fence, such as... Figures 1-2 As shown, the fence includes a fence body 1, connecting posts 2, and a base 3. The connecting posts 2 are located at the bottom of the fence body 1, and there are two connecting posts 2, which are distributed at both ends of the fence body 1. The base 3 is located below the fence body 1, and there are two connecting holes 4 on the base 3, which are arranged side by side. The two connecting holes 4 on the base 3 are rotatably connected to either of the two connecting posts 2 on the fence body 1.

[0024] For example, in implementation, the fence body 1 includes components such as railings and mesh to form physical and visual isolation.

[0025] The connecting post 2 is connected to the bottom of the fence by means of welding, screwing, or integral molding. There are two connecting posts 2, and the two connecting posts 2 are set opposite each other at the bottom ends of the fence body 1.

[0026] The top surface of the base 3 is provided with two connection holes 4, which are arranged side by side on the base 3.

[0027] During use, there are several bases 3 and several fence bodies 1.

[0028] In one optional implementation, firstly, a first base 3 is placed at the opening of the pit, and a connecting post 2 at one end of the first fence body 1 is inserted into a connecting hole 4 on the base 3. The first fence body 1 is then rotated around the connecting post 2 at one end as needed. Next, a second base 3 is placed below the other end of the first fence body 1, and the connecting post 2 at the other end of the first fence body 1 is inserted into a connecting hole 4 on the second base 3. Then, the connecting post 2 at one end of the second fence body 1 is inserted into another connecting hole 4 on the second base 3, and the second fence body 1 is rotated around the connecting post 2 at one end as needed. Repeating the aforementioned operations, several fence bodies 1 are sequentially joined end-to-end to form a continuous safety zone corresponding to the usage requirements. When the shape of the protective ring needs to be adjusted again, the position of the base 3 is adjusted according to the usage requirements, changing the included angle between adjacent fence bodies 1 to form different shaped safety zones corresponding to the usage requirements.

[0029] In another optional implementation, several bases 3 and several fence bodies 1 are placed around the opening of the pit. Next, the fence body 1 is positioned above the bases 3, and the connecting posts 2 of adjacent fence bodies 1, located at their closest points, are inserted into the two connecting holes 4 on the corresponding bases 3 (i.e., the bases 3 located below the closest points of the adjacent fence bodies 1), and the connecting posts 2 are rotatably connected to the connecting holes 4. Then, according to usage requirements, the position of the bases 3 is adjusted to change the included angle between adjacent fence bodies 1, thus forming a continuous safety zone of different shapes corresponding to usage needs.

[0030] The fence body 1 is rotatably connected to the connecting hole 4 on the base 3 via the connecting post 2, allowing the user to adjust the angle between two adjacent fence bodies 1 as needed. This aims to enable users to flexibly adjust the fence body 1 according to the on-site work area and protection requirements, adapting to the layout requirements of safety areas of different shapes.

[0031] In a preferred embodiment, to facilitate the movement and locking of the base 3, a caster wheel with a locking mechanism is provided below the base 3. The caster wheel with the locking mechanism is conventional technology and will not be described in detail here.

[0032] Example 2: To reduce the risk of accidental rotation of the fence body 1, based on Example 1 above, in this example, as... Figure 2 As shown, the safety fence also includes a first locking member 5; the first locking member 5 passes through the hole wall of the connecting hole 4, and the first locking member 5 is used to abut against the connecting post 2.

[0033] For example, in implementation, the aforementioned safety fence also includes a first locking member 5, which can be a pin, threaded rod, screw, or other similar structure. The first locking member 5 passes through the wall of the connecting hole 4, and can move in a direction away from or towards the axis of the connecting hole 4.

[0034] During use, firstly, move the first locking member 5 away from the axis of the connecting hole 4. Next, insert the connecting post 2 into the connecting hole 4. Then, after adjusting the position of the base 3, move the first locking member 5 closer to the axis of the connecting hole 4 until the first locking member 5 abuts against the side wall of the connecting post 2, forming a mechanical limit or frictional resistance between them. This aims to reduce the risk of accidental rotation of the fence body 1 or the connecting post 2 falling out of the connecting hole 4.

[0035] Example 3: When a large safety area needs to be enclosed, it may be necessary to connect multiple fence bodies 1 in a straight line. Therefore, to ensure the straightness between these multiple fence bodies 1, based on Example 1 above, in this example, as... Figure 2As shown, the safety fence also includes a guide plate 6 and a guide rod 7; the guide plate 6 is disposed on the base 3, and a guide hole 8 is provided on the guide plate 6; the guide rod 7 passes through the guide hole 8.

[0036] For example, in implementation, the aforementioned safety fence also includes a guide plate 6 and a guide rod 7. The guide plate 6 is fixed on the top surface of the base 3 by welding, screwing, or integral molding, and a guide hole 8 is provided on the surface of the guide plate 6. The axis of the guide hole 8 extends along the direction from one connecting hole 4 to another connecting hole 4 on the top surface of the base 3.

[0037] During use, the guide rods 7 are first inserted sequentially into the guide holes 8 on multiple bases 3, or multiple bases 3 are sequentially fitted onto the guide rods 7 through the guide holes 8. Next, multiple fence bodies 1 are sequentially connected to the bases 3. This is intended to achieve the goal of using the guide rods 7 as a physical baseline to align the bases 3 when the fence is laid out in a long straight line and it is difficult to ensure its straightness by visual inspection alone, thereby reducing "serpentine" or "zigzag" deviations.

[0038] Example 4: To facilitate movement, multiple fence bodies 1 are arranged in a straight line. Based on Example 3 above, in this example, as... Figure 2 As shown, the safety fence also includes a second locking member 9; the second locking member 9 passes through the guide plate 6 and abuts against the guide rod 7.

[0039] For example, during implementation, the above-mentioned safety protection fence also includes a second locking member 9. The second locking member 9 can be a structure such as a pin, screw, or bolt, and the second locking member 9 passes through the wall of the guide hole 8 on the guide plate 6.

[0040] During use, the second locking member 9 is first moved away from the axis of the guide hole 8. Next, the guide rod 7 is inserted into the guide hole 8. Then, the second locking member 9 is moved closer to the axis of the guide hole 8 until it abuts against the side wall of the guide rod 7, forming a mechanical limit or frictional resistance, thereby making the multiple linearly connected bases 3 a single unit. This aims to facilitate the user's movement of the multiple bases 3 and the multiple fence bodies 1 as a whole as needed.

[0041] Example 5: To reduce the risk of tilting of base 3, based on Example 1 above, in this example, as... Figure 2 As shown, the safety fence also includes a support post 10; the support post 10 passes through the base 3 and extends from the top of the base 3 to the bottom of the base 3.

[0042] During use, the aforementioned safety fence also includes a support post 10, and the support post 10 is installed on the base 3 along the direction from the top of the base 3 to the bottom of the base 3.

[0043] During use, the base 3 is placed near the pit, and the support column 10 is pressed firmly against the ground to provide anti-overturning reaction force, or inserted into the pre-drilled holes in the ground or into a soft base layer (such as soil or rubber pads) to enhance the anchoring effect. The aim is to ensure that when the fence body 1 is subjected to lateral forces (such as people leaning on it or equipment colliding with it), generating an overturning moment, the support column 10 forms an anti-overturning fulcrum, effectively resisting the moment and thus reducing the likelihood of the base 3 tilting or slipping.

[0044] Example 6: To facilitate adjustment of the support height of the support column 10, based on Example 5 above, in this example, as... Figure 2 As shown, the base 3 has a support hole 11, which extends from the top surface of the base 3 to the bottom surface of the base 3; the support column 10 passes through the support hole 11; the safety guardrail also includes a third locking member 12; the third locking member 12 passes through the base 3 and abuts against the support column 10.

[0045] For example, during implementation, the base 3 has a support hole 11 extending from the top surface of the base 3 to the bottom surface of the base 3, and the support column 10 passes through the support hole 11. The safety fence also includes a third locking member 12, which can be a pin, screw, bolt, or other structure, and the third locking member 12 passes through the hole wall of the support hole 11 and abuts against the side wall of the support column 10.

[0046] During use, the third locking member 12 is first moved away from the axis of the support hole 11. Next, the support column 10 is inserted into the support hole 11, and the height of the portion of the support column 10 below the base 3 is adjusted as needed. Then, the third locking member 12 is moved closer to the axis of the support hole 11 until it abuts against the side wall of the support column 10, forming a mechanical limit or frictional resistance, thereby making the multiple linearly connected bases 3 form a single unit. This aims to facilitate user adjustment of the support height of the support column 10 as needed. Simultaneously, it aims to reduce the risk of self-slippage of the support column 10, thereby ensuring the stability of the support column 10.

[0047] Example 7: Based on Example 1 above, in this example, as follows... Figure 1 As shown, the number of fence bodies 1 is set to N, and the N fence bodies 1 are connected end to end in sequence; where N≥3, and N is an integer.

[0048] For example, in the implementation process, the number of the above-mentioned fence bodies 1 is set to N, and the N fence bodies 1 are connected end to end. Wherein, N≥3, and N is an integer. The purpose is to make it convenient for users to use the N fence bodies 1 to form a minimum safe area, or to increase the number of fence bodies 1 as needed to form safe areas of different sizes.

[0049] In a preferred embodiment, safety belt attachment points can be provided on the base 3. During use, when workers are working near pits, they can hook their safety belts onto the safety belt attachment points on the base 3. This aims to improve the safety of the workers' working environment.
