Description

Technical Field

[0001] The utility model relates to the technical field of electrical wiring, in particular to an electrical wiring insulation protection device. Background Art

[0002] The insulating protective sleeve is used to wrap around the connection between two electrical wires for insulation protection.

[0003] In the prior art, Chinese patent CN215071600U published on 2021-12-07 discloses an insulation protection device for electrical wiring in a power plant. This patent achieves double protection by sliding the second protective sleeve into the first protective sleeve to prevent the cable wiring from being affected by external factors.

[0004] However, in these existing technologies, the protective sleeve's inherent strength is relied upon to achieve its protective effect. In reality, to achieve insulation, the sleeve is typically not made of metal, but rather of hard plastic. This type of sleeve can damage the external insulation of the connecting wires due to environmental factors, human error, and other factors. For example, excessive tightening of nuts and bolts during installation can easily cause cracks and failure, while impact can easily break during use. Furthermore, while the sleeve has a certain degree of resistance to spontaneous combustion, it can still be ignited by external flames. This can lead to electrical system failures and even safety hazards.

[0005] Therefore, an insulation protection device is proposed that can effectively improve the insulation performance of electrical wiring. Utility Model Content

[0006] The purpose of this utility model is to provide an electrical wiring insulation protection device that can improve the safety of the external insulation protection sleeve;

[0007] The utility model provides an electrical wiring insulation protection device, comprising: a protection mechanism, the protection mechanism comprising two connected protection covers, and the electrical wiring passes through the two protection covers; a fixing mechanism, the fixing mechanism comprising a first shell group and a second shell group, the first shell group and the second shell group respectively surrounding and clamping one of the protection covers; a support frame, the first shell group and the second shell group are connected to the support frame; and a fire prevention mechanism, the fire prevention mechanism is connected to the support frame and is located on the outside of the fixing mechanism.

[0008] Furthermore, two support frames are arranged in parallel, and a first vertical pole and a second vertical pole are connected to the support frame at intervals. The first vertical poles of the two support frames are connected to the first outer shell group, and the second vertical poles of the two support frames are connected to the second outer shell group.

[0009] Furthermore, the first shell group and the second shell group respectively include two spliced ​​half shells, one of the spliced ​​half shells is fixedly connected to the first vertical pole on the adjacent side through a fixing rod; the other spliced ​​half shell is abutted against the first vertical pole on the adjacent side through a threaded rod, and the threaded rod passes through and is threadedly connected to the first vertical pole on this side; when the threaded rod is screwed in, the threaded rod abuts against the spliced ​​half shell and moves toward the other spliced ​​half shell until the protective cover is clamped.

[0010] Furthermore, electrical wiring holes are provided at both ends of the protective cover, and connecting flanges are connected to adjacent sides of the two protective covers. A plurality of screws are connected through the connecting flanges at equal intervals, and the outer ends of the screws are locked by nuts.

[0011] Furthermore, the protective cover is made of insulating material.

[0012] Furthermore, the fire protection mechanism includes a vertical plate, which is arranged on the support frame and located between the first vertical pole and the second vertical pole.

[0013] Furthermore, adjacent inner sides of the vertical plates on the two support frames are respectively provided with fire extinguishing agent shells, and fire extinguishing agent is stored in the fire extinguishing agent shells.

[0014] Furthermore, the fire extinguishing agent shell is a plastic material shell, which can be broken in the event of fire or high temperature to allow the fire extinguishing agent to spray out.

[0015] Furthermore, it also includes a locking mechanism, which includes a fixed screw sleeve, the fixed screw sleeve is connected to the outer end of the protective sleeve, a thread groove is provided in the fixed screw sleeve and is connected to a movable thread ring, a clamping card is provided inside the movable thread ring, and a fixed ring is connected to one side of the clamping card.

[0016] Furthermore, the clamping cards are two symmetrical ones, and the two clamping cards are separated from one end of the fixing ring. When the threaded ring is rotated, the distance between the two clamping cards is adjusted.

[0017] The technical solution of this utility model is to surround and clamp an outer shell group on the outside of each of the two protective sleeves, and connect the two outer shell groups to the support frame. Therefore, when it is hit or accidentally bent by external forces, the support frame will take over the impact or external force due to the structure of the two outer shell groups and the support frame. Because both the protective sleeves and the outer shell groups can be made of insulating materials, the support frame can be made of higher-strength materials such as alloy rods, improving the stability of the electrical wiring and eliminating the risk of electrical conduction. In addition, the fireproofing mechanism improves fire resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] By enclosing and clamping a shell assembly on each side of the two protective sleeves 301 and connecting both shell assemblies to the support frame 1, when impacted or unexpectedly bent by external forces, the support frame 1 will bear the impact or external forces due to the structure of the two shell assemblies and the support frame 1. Because both the protective sleeves 301 and the shell assemblies can be made of insulating materials, the support frame 1 can be made of higher-strength materials such as alloy rods, improving the stability of the electrical wiring and eliminating the risk of electrical conduction. Furthermore, the fireproofing mechanism 5 improves fire resistance.

[0031] Example 2

[0032] Reference Figure 2 , Figure 3 Two support frames 1 are arranged in parallel, with a first vertical rod 1011 and a second vertical rod 1012 spaced apart and connected to each other. The first vertical rods 1011 of the two support frames 1 are connected to the first outer shell group 2021, and the second vertical rods 1012 of the two support frames 1 are connected to the second outer shell group 2022. The first outer shell group 2021 and the second outer shell group 2022 each include two spliced ​​half shells, one of which is fixedly connected to the adjacent first vertical rod 1011 via a fixing rod 203; the other spliced ​​half shell is abutted against the adjacent first vertical rod 1011 via a threaded rod 201, which passes through and is threadedly connected to the first vertical rod 1011 on that side. When the threaded rod 201 is screwed in, the threaded rod 201 abuts the spliced ​​half shell and moves toward the other spliced ​​half shell until the protective cover 301 is clamped.

[0033] Specifically, two support frames 1 are arranged in parallel, with two vertical poles symmetrically arranged at the upper ends of the support frame 1, namely a first vertical pole 1011 and a second vertical pole 1012.

The fixing rod 203 fixes the spliced ​​half shell to the vertical pole. Rotating the threaded rod 201 pushes one spliced ​​half shell toward the other spliced ​​half shell for locking and fixing.

[0034] Example 3

[0035] Reference Figure 3 The protective cover 301 has electrical wire holes at both ends. The adjacent sides of the two protective covers 301 are connected with connecting flanges 302. A plurality of screws 303 are evenly spaced and connected through the connecting flanges 302. The outer ends of the screws 303 are locked by nuts 304. The protective cover 301 is made of insulating material.

[0036] The protective cover 301 is made of insulating material, and the protective cover 301 is arranged inside the fixing mechanism 22, and a connecting flange 302 is connected to one side of the protective cover 301, and four screws 303 are evenly connected to the connecting flange 302 at equal intervals, and a nut 304 is connected to the outside of one end of the screw 303.

[0037] Example 4

[0038] Reference Figure 2 The fire prevention mechanism 5 includes a vertical plate 501, which is mounted on the support frame 1 and located between the first vertical pole 1011 and the second vertical pole 1012. Fire extinguishing agent housings 503 are located on adjacent inner sides of the vertical plates 501 on the two support frames 1. Fire extinguishing agent housings 503 contain fire extinguishing agent 502. Fire extinguishing agent housings 503 are made of plastic and can rupture in the event of a fire or high temperature, allowing the fire extinguishing agent 502 to be sprayed out.

[0039] The fire prevention mechanism 5 includes a vertical plate 501, which is arranged in the middle above the support frame 1. A fire extinguishing agent shell 503 is connected to one side of the vertical plate 501, and a fire extinguishing agent 502 is arranged inside the fire extinguishing agent shell 503.

[0040] Example 5

[0041] Reference Figure 4 , further comprising a locking mechanism 4, which includes a fixed screw sleeve 401 connected to the outer end of the protective sleeve 301. A threaded groove is provided within the fixed screw sleeve 401 and is connected to a movable threaded ring 402. A clamping clip 403 is provided within the movable threaded ring 402, and one side of the clamping clip 403 is connected to a fixed ring 404. The clamping clips 403 are symmetrical and separated at one end away from the fixed ring 404. When the movable threaded ring 402 is rotated, the distance between the two clamping clips 403 is adjusted.

[0042] The locking mechanism 4 includes a fixed screw sleeve 401, which is connected to one side of the protective mechanism 3, and a thread groove is provided inside the fixed screw sleeve 401. A movable thread ring 402 is provided inside the fixed screw sleeve 401, and a thread that matches the internal thread groove of the fixed screw sleeve 401 is provided on the movable thread ring 402. The fixed screw sleeve 401 and the movable thread ring 402 are matched. A clamping card 403 is provided inside the movable thread ring 402, and a fixed ring 404 is connected to one side of the clamping card 403. When the two clamping cards 403 are parallel, the distance between the inner walls gradually expands from one end away from the fixed ring 404 to one end close to the fixed ring 404. Therefore, when the movable thread ring 402 is rotated and moved in the direction away from the fixed ring 404, the opening between the two clamping cards 403 becomes smaller, the distance is reduced, and the clamping of the electrical wiring is tighter. When moving in the opposite direction, the clamping is looser. Adjustment can be made. Specifically, the structure of the expansion screw 303 can be referred to.

[0043] Working Principle: First, select the appropriate connecting wire and ensure that its conductivity meets the requirements. Then, insert the connecting wire into the protective mechanism 3 through the locking mechanism 4. Secure the protective sleeves 301 on both sides with screws 303 and nuts 304. Rotate the threaded rod 201, which pushes one half shell toward the other, clamping the protective mechanism 3. Adjust the fixed screw sleeve 401 and the movable threaded ring 402 to flexibly adjust the clamping card 403. By installing the fire prevention mechanism 5, the safety of the device is further improved, reducing losses caused by emergencies.
