Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment: a combined fiberglass protective net, including a protective part, with positioning parts on both sides of the protective part. The protective part and the positioning parts on the left and right sides are connected to form a protective net. The positioning part includes a second truncated pyramid 1, with an upwardly protruding square post 21 at the top of the second truncated pyramid 1, and a first truncated pyramid 22 at the top of the square post 21. The protective part includes an upper rod 31 and a lower rod 32, with a railing 33 inserted between the upper rod 31 and the lower rod 32. A protruding block 23 is provided on the side wall of the square post 21, with a through hole 231 on the block 23. The left and right sides of the bottom of the upper rod 31 have downwardly protruding pivots 333, which can pass through the hole 231. The lower rod 32 has through holes 321 on both sides. The side wall of the square column 21 also has a protruding block 24 with through holes 241. Locking parts 4 are inserted into holes 241 and 231. Locking parts 4 can be pressed into holes 231 and 241. The protective part and the positioning parts on both sides form a protective net to block dangerous areas. Locking parts 4 can be automatically pressed into holes 231 and 241, which facilitates the simultaneous combination of the positioning parts on both sides, increases the convenience of combination, and enables the rapid construction of the protective net. Locking parts 4 can be manually pulled down and can be easily removed when not needed.

[0023] Please see Figure 1 - Figure 4 In this embodiment, the railings 33 on the left and right sides of the protective part are respectively provided with lugs 331 protruding towards the positioning part. The lugs 331 are provided with through holes 3311. The locking member 4 can move up and down within holes 231, 241 and 3311. By moving the locking member 4 downward within holes 231, 241 and 3311, the locking and unlocking functions of the combined protective net are realized, which is convenient and quick. At the same time, the locking member 4 can rotate within holes 231, 241 and 3311, increasing the applicability of the protective net. The locking member 4 includes an upper insertion post 41, a partition 42 at the bottom of the upper insertion post 41, a lower insertion post 43 at the bottom of the partition 42, and a countersunk hole 411 at the top axis of the upper insertion post 41. A cylindrical head screw 40 can be inserted into the countersunk hole 411 to connect with the partition 42 and the lower insertion post 43. The locking part 4, which is spliced ​​together, can block the locking part 4 and avoid interference caused by the overall installation of the locking part 4. The lower insertion post 43 is inserted into the third hole 3311, and the upper insertion post 41 is inserted into the second hole 241. The partition 42 is located below the lower rod 32. A spring 421 is sleeved on the outer diameter of the lower insertion post 43. The spring 421 is located on the top of the lug 331. The spring 421 can push against the partition 42 to make the locking part 4 spring upward. The spring 421 realizes automatic pressure on the partition 42, so that the upper insertion post 41 can be continuously sent into the second hole 241 when the spring 421 is not compressed, thereby strengthening the connection strength of the protective net.

[0024] Please see Figure 2 - Figure 5 In this embodiment, the front side of the second prism 1 is provided with a placement opening 12, and a counterweight can be placed inside the first block 23. The top of the second prism 1, corresponding to the outer edge of the square column 21, is provided with an insertion opening 11. A baffle 14 can be inserted into the insertion opening 11 to block the placement opening 12. The counterweight inside the placement opening 12 lowers the center of gravity of the positioning part, making the positioning part more stable and reducing the possibility of tipping over. At the same time, the removable counterweight can reduce fatigue when the positioning part is being transported. The bottom of the placement opening 12 is provided with a slot 110 corresponding to the insertion opening 11. The bottom of the baffle 14 can be inserted into the slot 110. By inserting the baffle 14 into both the insertion opening 11 and the slot 110, it is convenient to block the placement opening 12. The counterweight in section 2 is limited to prevent it from slipping out of the placement opening 12 and being lost. The side wall of the second truncated pyramid 1 is provided with a locking hole 131 corresponding to the position of the slot 110. A semi-circular head screw 13 can be inserted into the locking hole 131. The semi-circular head screw 13 includes a screw rod 132. The screw rod 132 can reach into the slot 110. When the baffle 14 is in the slot 110, the baffle 14 is provided with a positioning groove 141 corresponding to the position of the screw rod 132. The locking hole 131 has a threaded surface that matches the screw rod 132. The positioning groove 141 of the baffle 14 is pressed by the semi-circular head screws 13 on both sides of the baffle 14 to prevent the baffle 14 from accidentally moving upward and falling off.

[0025] When in operation, the protective net formed by the positioning and protective parts is only used to protect against hazards that do not have the ability to collide, cross, or spread. It is mainly used in power system accidents, such as when step voltage forms on the ground. The positioning and protective parts are made of fiberglass, which has excellent insulation capabilities. At the same time, the configuration blocks in the placement port 12 are made of overlapping mica sheets. When it is necessary to combine the positioning and protective parts, first, place the two positioning parts with a gap, the gap being the distance between the two ends of the protective part. Then, tilt the protective part to one side so that the top of the upper insertion post 41 abuts against the second block 24, forcing the spring 421 to press down. Then, insert the rotating shaft 333 into the hole 231 from the upper side of the first block 23. Then tilt... The protective part is vertical, causing the upper insert 41 to fall into the hole 241 of the second block 24, thus completing the assembly. This is very convenient and quick. A counterweight needs to be placed in the placement opening 12 beforehand. Specifically, unscrew the semi-circular head screws 13 on both sides of the second truncated pyramid 1, then pull out the baffle 14, put the counterweight into the placement opening 12, and then release the baffle 14 so that the bottom of the baffle 14 falls into the slot 110. Then tighten the semi-circular head screws 13 so that the locking hole 131 enters the positioning slot 141. This way, the baffle 14 cannot be easily pulled out. The positioning part can rotate relative to the protective part to meet different placement needs and increase adaptability. The spring 421 can be covered with elastic insulating rubber as needed.

[0026] Through the above steps, the protective part and the positioning parts on both sides form a protective net that can shield dangerous areas. The locking part 4 can be automatically squeezed into the holes 231 and 241, which makes it easy to combine the positioning parts on both sides at the same time, increasing the convenience of combination and enabling the protective net to be built quickly. The locking part 4 can be manually controlled to pull down, and can be easily removed when not needed, so as to solve the problem that the combination of the protective structure in the prior art requires the simultaneous insertion of four adjusting rods, which increases the difficulty of combination and the time of combination.
