Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3As shown, an electrical high-voltage test safety isolation and protection device includes a guardrail (101); three first connecting blocks (102) are fixedly connected to one end of the guardrail (101); a first gear ring (103) is fixedly connected to the end of the first connecting block (102) away from the guardrail (101); three second connecting blocks (104) are fixedly connected to the end of the guardrail (101) away from the first connecting block (102); the second connecting blocks (104) are located at the upper end of the first connecting blocks (102); a second gear ring (105) is fixedly connected to the end of the second connecting block (104) away from the guardrail (101); a support base (107) is located on the outside of the guardrail (101); an equally spaced serrated column (106) is fixedly connected to the upper end of the support base (107); the equally spaced serrated column (106) is slidably engaged with the second gear ring (105) and the first gear ring (103).

[0025] During operation, the staff places the support base (107) and the serrated columns (106), then moves the guardrail (101) and places the first gear ring (103) and the second gear ring (105) on the outside of the serrated columns (106). Then the guardrail (101) is placed down. This step, through the structural design of the first gear ring (103), the second gear ring (105) and the serrated columns (106), can reduce the lateral sway of the guardrail (101) during rapid assembly. At the same time, the angle between multiple guardrails (101) can be adjusted according to the needs, thereby greatly improving the layout flexibility of the electrical high voltage test site while ensuring assembly efficiency.

[0026] like Figure 1-4 As shown, a slot block (201) is provided on the outer side of the guardrail (101); the slot block (201) is slidably engaged with the support base (107); a connecting post (202) is fixedly connected to the lower end of the slot block (201); a disc (203) is fixedly connected to the outer side of the connecting post (202).

[0027] During operation, in special scenarios, workers can bury the disc (203) and connecting column (202) in the ground, and then slide the support base (107) into the inside of the slot block (201) to increase the stability of the device. In special working scenarios, this step, by firmly burying the disc (203) and connecting column (202) in the ground to form a stable support foundation, and then sliding the support base (107) into the inside of the slot block (201) to achieve further reinforcement, significantly improves the structural stability of the entire device.

[0028] like Figure 1-5As shown, the upper end of the equally spaced serrated column (106) is fixedly connected to a threaded rod (301); the outer side of the threaded rod (301) is threadedly connected to a threaded sleeve (302); the lower end of the threaded sleeve (302) is rotatably connected to a connecting ring (303); the lower end of the connecting ring (303) is fixedly connected to a first serrated ring (304).

[0029] During operation, the first serrated ring (304) is fitted onto the outside of the equidistant serrated post (106), and then the threaded sleeve (302) is rotated, causing the threaded sleeve (302) to move longitudinally. When the threaded sleeve (302) moves longitudinally, it drives the first serrated ring (304) to move longitudinally through the connecting ring (303), causing the first serrated ring (304) to abut against the second gear ring (105). Then, the threaded sleeve (302) is threadedly connected to the equidistant serrated post (106), thereby restricting the equidistant serrated post (106). 6) Longitudinal movement: In this step, the first sawtooth ring (304) is sleeved on the outside of the equidistant sawtooth column (106), and the rotating threaded sleeve (302) drives the first sawtooth ring (304) to move longitudinally through the connecting ring (303) until the first sawtooth ring (304) abuts against the second gear ring (105). At the same time, the longitudinal movement of the equidistant sawtooth column (106) is effectively restricted by the threaded connection between the threaded sleeve (302) and the equidistant sawtooth column (106), thereby making the device more stable.

[0030] like Figure 3-4 As shown, the guardrail (101) has four limiting grooves (401) on its inner side; a first limiting plate (402) is fixedly connected to the outer side of the first serrated ring (304); the first limiting plate (402) is slidably engaged with the limiting groove (401); a second serrated ring (403) is fixedly connected to the outer side of the lower end of the equally spaced serrated column (106); a second limiting plate (404) is fixedly connected to the outer side of the second serrated ring (403); the second limiting plate (404) is slidably engaged with the limiting groove (401).

[0031] During operation, by sliding the second limiting plate (404) and the first limiting plate (402) into and engaging them with the inner side of the limiting groove (401), the stability of the device under special circumstances is significantly enhanced, and the overall structural robustness is improved.

[0032] like Figure 5 As shown, an indicator light (501) is fixedly connected to the upper end of the threaded sleeve (302). When in operation, the indicator light (501) provides a warning function at night, effectively enhancing environmental visibility and safety, ensuring that personnel can identify the environment, and thus reducing misunderstandings that may occur due to poor visibility at night.

[0033] like Figure 4As shown, a plurality of serrated blocks (601) are fixedly connected to the outer side of the threaded sleeve (302); during operation, the friction between the threaded sleeve (302) and the operator's hand is increased by the serrated blocks (601), which significantly improves the ease of operation when rotating the threaded sleeve (302), reduces the operational difficulties caused by slippage or insufficient force, and effectively improves work efficiency.

[0034] like Figure 1-3 As shown, reflective paper (701) is fixedly connected to the end of the guardrail (101). During operation, the reflective paper (701) reflects light, significantly improving the visibility of the device in low light or nighttime environments, which helps staff to quickly and accurately identify the location and status of the device.

[0035] The working principle of this utility model is as follows:

[0036] The staff placed the support base (107) and the serrated columns (106), then moved the guardrail (101) to place the first gear ring (103) and the second gear ring (105) on the outside of the serrated columns (106), and then placed the guardrail (101) down. This step, through the structural design of the first gear ring (103), the second gear ring (105), and the serrated columns (106), reduces the lateral sway of the guardrail (101) during rapid assembly. Simultaneously, the angles between multiple guardrails (101) can be adjusted according to requirements, thereby greatly improving the layout flexibility of the electrical high-voltage test site while ensuring assembly efficiency.

[0037] In special scenarios, workers can bury the disc (203) and connecting column (202) in the ground, and then slide the support base (107) into the inside of the slot block (201) to increase the stability of the device. In this step, under special working conditions, by firmly burying the disc (203) and connecting column (202) in the ground to form a stable support foundation, and then sliding the support base (107) into the inside of the slot block (201) for further reinforcement, the structural stability of the entire device is significantly improved.

[0038] The first serrated ring (304) is fitted onto the outside of the serrated column (106), and then the threaded sleeve (302) is rotated to make the threaded sleeve (302) move longitudinally. When the threaded sleeve (302) moves longitudinally, the first serrated ring (304) is driven to move longitudinally through the connecting ring (303), so that the first serrated ring (304) abuts against the second gear ring (105). Then, the threaded sleeve (302) is threadedly connected to the serrated column (106) to restrict the longitudinal movement of the serrated column (106). In this step, by sleeved the first serrated ring (304) on the outside of the equidistant serrated column (106), and the rotating threaded sleeve (302) drives the first serrated ring (304) to move longitudinally through the connecting ring (303) until the first serrated ring (304) abuts against the second gear ring (105). At the same time, the longitudinal movement of the equidistant serrated column (106) is effectively restricted by the threaded connection between the threaded sleeve (302) and the equidistant serrated column (106), thereby making the device more stable. By sliding the second limiting plate (404) and the first limiting plate (402) into and engaging with the inner side of the limiting groove (401), the stability of the device under special conditions is significantly enhanced, and the overall structural robustness is improved.

[0039] After the indicator light (501) is activated, it can provide a prompting function at night, effectively enhancing environmental visibility and safety, ensuring that personnel can identify the environment, thereby reducing misunderstandings that may occur due to poor visibility at night.

[0040] By increasing the friction between the threaded sleeve (302) and the worker's hand by using the serrated block (601), the ease of operation when rotating the threaded sleeve (302) is significantly improved, the operational difficulties caused by slippage or insufficient force are reduced, and the work efficiency is effectively improved.

[0041] The reflective paper (701) significantly improves the visibility of the device in low light or nighttime environments, helping staff to quickly and accurately identify the location and status of the device.

[0042] In the description of this specification, the terms "connection", "installation", "fixing", "setting", etc. are interpreted in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
