[0023] The portable protective fence for power engineering provided by the present invention, compared with the prior art, can be used to fill air into the foldable telescopic tube 4 through the inflatable piece during use, so that the foldable telescopic tube 4 expands and stretches, the cover plate 3 moves upward to pull the belt roll 51 out of the telescopic belt box 5, and then a warning tape 6 is connected between the belt rolls 51 on two adjacent columns 1 to form a fence; when the fence needs to be used up, the warning tape 6 is removed to release the air in the foldable telescopic tube 4, and the foldable telescopic tube 4 is compressed to change it from an extended state to a compressed state, so that the volume of the column 1 can be reduced, making it easy to store and carry.

[0024] In this embodiment, the foldable telescopic tube 4 is a plastic telescopic tube made of hard plastic. The two ends of the foldable telescopic tube 4 are respectively sealed and connected to the cover plate 3 and the base 2 to form a sealed chamber inside the foldable telescopic tube 4. After air is filled into the foldable telescopic tube 4, the foldable telescopic tube 4 is extended and has a certain anti-bending ability.

[0025] In some embodiments, see Figure 6 to Figure 7A first hole body 201 is provided on the upper end surface of the base 2. The first hole body 201 is a longitudinal blind hole provided in the middle of the base 2. The lower end of the folding telescopic tube 4 is covered on the first hole body 201. A cover 21 is connected to the upper end of the first hole body 201. The cover 21 can be connected to the first hole body 201 through a thread. A connecting hole 211 is provided through the middle of the cover 21. The connecting hole 211 connects the first hole body 201 and the inner cavity of the folding telescopic tube 4. A sealing plug 22 is slidably provided inside the first hole body 201. In application, a sealing ring can be sleeved on the sealing plug 22. When in use, the sealing ring is squeezed to form a sealing connection with the side wall of the first hole body 201. In this embodiment, an elastic member is provided between the sealing plug 22 and the sealing cover 21, and the elastic member is a coil spring 23. When the folding telescopic tube 4 is in the folded state, the coil spring 23 presses the sealing plug 22 against the bottom of the first hole body 201. In this embodiment, a traction rope 9 is connected to the upper end of the sealing plug 22, and the other end of the traction rope 9 passes through the coil spring 23 and the connecting hole 211 on the sealing cover 21 in turn and is placed in the folding telescopic tube 4, and extends upward to be connected to the cover plate 3. In this embodiment, the number of traction ropes 9 can be one or more, and the specific number is not limited. When the folding telescopic tube 4 is in the folded state, the traction rope 9 is in a relaxed state.

[0026] A first accommodating groove 202 is also provided on the base 2. Specifically, the first accommodating groove 202 is opened on the side wall of the base 2. The first accommodating groove 202 is located on one side of the first hole body 201. The above-mentioned inflatable member is a high-pressure gas cylinder 8 arranged in the first accommodating groove 202. An air inlet hole 204 is provided between the first accommodating groove 202 and the first hole body 201. The air inlet hole 204 is connected to the high-pressure gas cylinder 8 through a one-way valve 24 at one end close to the first accommodating groove 202. The other end of the air inlet hole 204 passes through the side wall of the first hole body 201, and a longitudinally penetrating air hole 221 is provided in the middle of the sealing plug 22. In use, a predetermined weight of air is stored in the high-pressure gas cylinder 8. When the foldable telescopic tube 4 is in a folded state, the sealing plug 22 is located at the bottom of the first hole body 201, and the side wall of the sealing plug 22 blocks the air inlet. Hole 204, the high-pressure air in the high-pressure gas cylinder 8 cannot enter the foldable telescopic tube 4 through the one-way valve 24. When the foldable telescopic tube 4 needs to be inflated, the cover plate 3 can be pulled upward to manually lengthen the foldable telescopic tube 4. When the cover plate 3 moves upward, the traction rope 9 changes from a relaxed state to a tensioned state, so that the cover plate 3 can drive the sealing plug 22 in the first hole body 201 to move upward through the traction rope 9, so that the bottom of the sealing plug 22 moves to above the air inlet hole 204, and the seal of the air inlet hole 204 is released, so that the high-pressure gas in the high-pressure gas cylinder 8 enters the foldable telescopic tube 4 through the air inlet hole 204, the vent hole 221 and the connecting hole 211 in turn, and the high-pressure air is filled into the foldable telescopic tube 4 to support the foldable telescopic tube 4, so that the pressure resistance and bending resistance of the foldable telescopic tube 4 are improved.

[0027] In some embodiments, see Figure 6 to Figure 7 An exhaust hole 301 is provided through the middle of the cover plate 3 from top to bottom, and the exhaust hole 301 is connected to the inner cavity of the foldable telescopic tube 4. An exhaust plug 32 is threadedly connected to the upper end of the exhaust hole 301. In application, when the foldable telescopic tube 4 needs to be compressed, the exhaust plug 32 can be removed from the exhaust hole 301 to make the inner cavity of the foldable telescopic tube 4 communicate with the outside world, so that the high-pressure gas inside the foldable telescopic tube 4 is discharged into the atmosphere, and the cover plate 3 can be moved downward to compress the foldable telescopic tube 4 to put it in a folded state and reduce its volume. When the foldable telescopic tube 4 is compressed, the sealing plug 22 located in the first hole body 201 moves downward under the elastic force of the coil spring 23 and abuts against the bottom of the first hole body 201, and the sealing plug 22 re-seals the air inlet hole 204.

[0028] In some embodiments, see Figure 7 The first receiving groove 202 passes through the side wall of the base 2 and is provided with a storage opening, and a sealing plug 25 is provided on the storage opening. In application, the sealing plug 25 can be connected to the storage opening by a thread. After removing the sealing plug 25, the high-pressure gas cylinder 8 can be inserted into the first receiving groove 202 through the storage opening, and then the sealing plug 25 is connected to the storage opening. By rotating the sealing plug 25, the sealing plug 25 can be pressed inwardly against the high-pressure gas cylinder 8, so that the inflation port of the high-pressure gas cylinder 8 is connected to the one-way valve 24, and the high-pressure gas cylinder 8 is triggered to be inflated.

[0029] In some embodiments, see Figures 2 to 6 A locking component 7 is provided between the base 2 and the cover plate 3. In the present embodiment, there are two locking components 7, which are symmetrically arranged on both sides of the foldable telescopic tube 4.

The pull ring 71 is arranged on the upper end surface of the base 2, and one end of the zipper 72 is connected to the lower end surface of the cover plate 3. A hook 73 is provided at the other end of the zipper 72. When the foldable telescopic tube 4 is in a retracted state, the hook 73 can be hung on the pull ring 71 to limit the base 2 and the cover plate 3 from moving away from each other. Through the above arrangement, the problem of the base 2 and the cover plate 3 automatically separating during transportation, which causes the foldable telescopic tube 4 to be stretched, can be avoided.

[0030] Optionally, a handle 31 is provided on the upper end surface of the cover plate 3 to facilitate the transfer and operation of the column 1.

[0031] In some embodiments, see Figure 6 to Figure 7A second receiving groove 203 is also provided on the base 2, and the second receiving groove 203 is used to place the warning tape 6. Specifically, the second receiving groove 203 is arranged on the side wall of the base 2 and is located on the opposite side of the first receiving groove 202. A movable door 26 is arranged on the side wall of the base 2 corresponding to the second receiving groove 203. One side of the movable door 26 is hinged to the base 2, and the other side is movably connected to the base 2 through a magnetic suction member. In this embodiment, the movable door 26 cover is arranged on the notch of the second receiving groove 203, and is used to block the second receiving groove 203 to prevent the warning tape 6 placed in the second receiving groove 203 from falling out.

[0032] In some embodiments, see Figure 2 , Figure 4 and Figure 8 The above-mentioned tape roll 51 is penetrated by a connecting hole 511, and a connecting rod 61 is provided at the end of the warning tape 6. In this embodiment, the connecting hole 511 is an oblong hole, and the length of the oblong hole is equivalent to the width of the warning tape 6. The length of the connecting rod 61 is slightly wider than the width of the warning tape 6. When in use, the connecting rod 61 is first placed horizontally, so that the connecting rod 61 passes through the connecting hole 511, and then the connecting rod 61 is placed longitudinally, so that the connecting rod 61 can be inserted into the connecting hole 511. By cooperating with the connecting hole 511, the warning tape 6 is connected to the tape roll 51, and the warning tape 6 can be prevented from being separated from the tape roll 51.
