Description

Technical Field

[0001] This invention relates to the field of power engineering equipment technology, and in particular to a safety telescopic fence for power engineering. Background Technology

[0002] Electrical engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering projects that use electricity as a power source and energy source in various fields. In electrical engineering, fences need to be set up around electrical equipment. These fences are mostly retractable and are used to prevent people from accidentally entering, serving as a protection for electrical facilities and a warning to people.

[0003] Currently, to ensure the stability of the fence, triangular angle irons or reinforcing ribs are often added to the longitudinal bars of the fence for support. The connection method is usually direct welding or bolt fastening. However, in actual use, this connection method results in a fixed inverted T-shaped structure between the angle iron or reinforcing rib and the longitudinal bar. Therefore, when installing the fence on some rugged or sloping roads, the longitudinal bar is prone to tilting due to the influence of the angle iron or reinforcing rib. It also increases the space occupied when storing the fence and makes it inconvenient to carry. Summary of the Invention

Detailed Implementation

[0073] This invention provides a telescopic safety fence for power engineering, which solves the technical problems of existing power engineering safety fences, which are prone to tilting when placed on rugged or sloping roads due to the influence of angle iron or reinforcing ribs, and also cause additional space occupation and inconvenience in carrying when the fence is stored.

[0074] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0075] It is worth mentioning that pulling the post 1 will cause the folding fence 2 to extend or retract to the appropriate position, and connect the post 1 to the ground to complete the installation. In order to ensure the stability of the fence, triangular angle irons or reinforcing ribs will be added to the longitudinal bars of the fence measuring tool to provide support. The connection method is generally direct welding or bolt fastening. However, in actual use, the angle iron or reinforcing ribs and the longitudinal bars form a fixed inverted T-shaped structure. Therefore, when installing on some rugged or sloping roads, the longitudinal bars are prone to tilting due to the influence of the angle iron or reinforcing ribs. In addition, this design will also increase the unnecessary space occupied when storing the fence, making it inconvenient to carry.

[0076] Please see Figure 1 The present invention provides a safety telescopic fence for power engineering, comprising opposing posts 1, folding fence 2 installed between the posts 1, and grounding mechanism 3 installed on the posts 1;

[0077] The grounding mechanism 3 includes a stabilizing component 31, a storage component 32, an adjusting component 33, and a fixing component 34;

[0078] The stabilizing component 31 is hinged and installed in the column slots A opened on both sides of the bottom of the column 1;

[0079] The storage component 32 is inserted into the column slot A and located on one side of the column 1;

[0080] The adjusting component 33 is rotatably connected to the column slot B opened on the surface of the column 1;

[0081] The fixing component 34 is installed inside the adjusting component 33, and the fixing component 34 is slidably connected to the adjusting component 33.

[0082] In this embodiment of the invention, by adjusting the stabilizing component 31, the stabilizing component 31 is rotated to a suitable angle and fixed to the column 1. This assists the operator in adjusting the placement angle of the column 1 according to the site conditions. Then, the adjusting component 33 is pushed to rotate along the column 1 to a suitable angle and connect with the ground. The adjusting component 33 is then fixed by the fixing component 34, achieving multi-point contact with the ground and ensuring placement stability. Alternatively, the stabilizing component 31 can be pushed to store the stabilizing component 31 into the column 1, and the stabilizing component 31 is fixed to the column 1 by the storage component 32, completing the storage. At the same time, the adjusting component 33 is separated from the column 1, thereby reducing the occupied area and making it convenient to carry.

[0083] Please see Figure 1 and Figure 2 The present invention provides a safety telescopic fence for power engineering, wherein the stabilizing component 31 includes an mounting plate 311 hinged in the column slot A and a sliding plate 314 welded to the inner wall of the column slot A and located on one side of the mounting plate 311.

[0084] The surface of the slide plate 314 is fitted with a slide block 315;

[0085] A hinge plate 313 is hinged to one side of the surface of the slide 315, and the side of the hinge plate 313 away from the slide 315 is hinged to the inner wall of the mounting plate 311.

[0086] A positioning bolt 316 is screwed onto one side of the slide 315, which is located on the hinge plate 313.

[0087] A connector plate 312 is inserted into a slot on the side of the mounting plate 311 away from the hinge plate 31.

[0088] In this embodiment of the invention, while the mounting plate 311 is pushed to rotate along the column 1, the mounting plate 311 pulls the slide block 315 along the slide plate 314 to a suitable position through the hinge plate 313. At this time, the slide plate 314 and the slide block 315 are connected by the rotating positioning bolt 316 to fix the angle of the mounting plate 311, so that the operator can make appropriate adjustments to the placement angle of the column 1 according to the site conditions.

[0089] Please see Figure 1 and Figure 2 The present invention provides a safety telescopic fence for power engineering, wherein the mounting plate 311 has a locking strip on both sides of the slot corresponding to the limiting groove on both sides of the surface of the plug plate 312.

[0090] The card strip is inserted into the limiting groove;

[0091] Both the mounting plate 311 and the plug-in plate 312 have through grooves on their surfaces, and the through grooves of the mounting plate 311 and the plug-in plate 312 are connected.

[0092] In this embodiment of the invention, the plug plate 312 is pulled out from the mounting plate 311 to increase the contact area between the column 1 and the ground. The mounting plate 311 and the plug plate 312 are connected to the ground simultaneously by external bolts to enhance the connection stability. The retaining strip is used to increase the connection strength between the plug plate 312 and the mounting plate 311, ensure the stability of the plug plate 312 when it moves, and prevent the plug plate 312 from slipping out.

[0093] Please see Figure 3 and Figure 4 The present invention provides a safety telescopic fence for power engineering, wherein the storage component 32 includes a push block 321 inserted into the inner wall groove of the column slot A and an insert block 323 welded to one side of the surface of the push block 321.

[0094] Slider 322 is welded to both sides of the surface of push block 321 at positions corresponding to the inner wall of the slide groove, and slider 322 is slidably connected in the slide groove;

[0095] The insert 323 has cavities on both sides, and a lever 326 is hinged in the cavity;

[0096] A rectangular locking block 328 is welded to one side of the surface of the dial plate 326, and a spring A327 is fixedly provided on the side of the dial plate 326 facing the inner wall of the cavity of the insertion block 323.

[0097] The end of spring A327 away from the dial plate 326 is fixedly connected to the insert block 323.

[0098] In this embodiment of the invention, in conjunction with the above, while the mounting plate 311 is being stored inside the column 1, the push block 321 is pushed downward to drive the insert block 323 into the corresponding connecting groove on the surface of the plug plate 312. At this time, the spring A327 is pushed back by the force to push the lever 326 to flip, and the lever 326 pushes the locking block 328 to lock into the fixing groove on the inner wall of the connecting groove of the plug plate 312, thereby completing the fixing of the plug plate 312, thereby realizing folding and storage, reducing the occupied area, and making it convenient for operators to carry and operate.

[0099] Please see Figure 3 and Figure 4 The present invention provides a safety telescopic fence for power engineering, wherein the surface of the insert 323 is slidably fitted with a plate sleeve 324 on one side of the cavity;

[0100] L-shaped extrusion blocks 325 are welded to the inner walls of the sleeve 324 at positions corresponding to the chambers.

[0101] The side of the extrusion block 325 away from the sleeve 324 abuts against the inclined surface of the push plate 326.

[0102] It is worth mentioning that, Figure 3 for Figure 2 In the right view, push block 321 and insert block 323 are fixed together, and push block 321 is located in front of insert block 323. Figure 4 The cross-sectional view of the insert 323 shows the specific internal structure of the insert 323, and the cross-section of the sleeve 324 shows that the sleeve 324 is fitted onto the surface of the insert 323.

[0103] In this embodiment of the invention, in conjunction with the above, while the push plate sleeve 324 drives the pressing block 325 to move, the pressing block 325 provides stress guidance to the inclined surface of the push plate 326, causing the push plate 326 to flip in the opposite direction, thereby separating the locking block 328 from the plug-in plate 312, making it convenient for the operator to take out the mounting plate 311 for installation.

[0104] Please see Figure 4 The plate sleeve 324 is bidirectional (i.e., push-pull). The plate sleeve 324 does not need to be pulled. That is, the push plate 326 is pressed by force to reset the plate sleeve 324. At this time, the plate sleeve 324 can only apply pressure to the push plate 326 by manual pushing.

[0105] Please see Figure 5 The present invention provides a safety telescopic fence for power engineering, wherein the adjustment component 33 includes a sleeve A331 welded into the groove B of the column and a sleeve B336 slidably sleeved on the surface of the sleeve A331.

[0106] A knob 333 is rotatably connected to the end of sleeve A331 away from column 1;

[0107] One end of the knob 333 inserted into the sleeve A331 is welded with a screw A332, and a screw sleeve A334 is screwed onto the surface of the screw A332;

[0108] Fixing blocks 335 are welded on both sides of the threaded sleeve A334 at the positions corresponding to the openings on the surface of the sleeve A331, and insert plates 3351 are inserted into the fixing blocks 335.

[0109] A spring B3352 is fixedly provided on one side of the insert plate 3351 that is inserted into the fixing block 335, and the end of the spring B3352 away from the insert plate 3351 is fixedly connected to the fixing block 335.

[0110] The surface of the insert plate 3351 abuts against the surface of the sleeve B336, and a connecting plate 337 is welded to one side of the surface of the sleeve B336.

[0111] A rod A338 is rotatably connected to the movable cavity of the connecting plate 337 on the side away from the sleeve B336 via a rotating shaft;

[0112] Insert rod B3381 is inserted into insert rod A338;

[0113] Insert rod B3381 is welded to the end away from insert rod A338 with insert rod C339.

[0114] It is worth mentioning that you should refer to Figure 5 The location of the opening on the surface of sleeve A331 refers to the surface of sleeve A331. According to the distribution of the fixing block 335, since sleeve A331 is a hollow tube, the opening can only be opened on the surface of sleeve A331, and the fixing block 335 is inside the opening.

[0115] It is worth mentioning that the insert plate 3351 is inserted into the fixing block 335, and the spring B3352 is located inside the fixing block 335, and the two ends of the spring B3352 are fixed to the insert plate 3351 and the fixing block 335 respectively.

[0116] In this embodiment of the invention, pushing the sleeve B336 causes the connecting plate 337 to rotate along the sleeve A331 to a suitable angle, and rotating the knob 333 causes the threaded sleeve A334 to move the insert plate 3351 along the screw A332 through the fixing block 335 until the spring B3352 abuts against the sleeve B336, thus completing the fixing of the sleeve B336, thereby assisting the operator in adjusting the position of the insert rod A338.

[0117] It is worth mentioning that the connecting plate 337 rotates along the sleeve A331 via the sleeve B336. The sleeve B336 is slidably fitted on the surface of the sleeve A331. Therefore, while the sleeve B336 is rotated under force, the connecting plate 337, which is fixed to the sleeve B336, can also rotate via the sleeve A331.

[0118] It should be noted that by pressing the insert plate 3351 to retract it into the fixing block 335, the sleeve B336 can be pulled to separate the sleeve B336 from the sleeve A331, thereby sorting and storing it for easy carrying and operation by the workers.

[0119] Please see Figures 5-7 The present invention provides a safety telescopic fence for power engineering, wherein the insert plate 3351 has cavities on both sides, and a flap 3353 is hinged to one side of the inner wall of the cavity.

[0120] A hinge rod 3354 is hinged to the side of the flap 3353 facing the inner wall of the cavity;

[0121] The hinge rod 3354 is hinged to a sliding sleeve 3355 on the side away from the flap 3353;

[0122] A spring C3356 is inserted into the sliding sleeve 3355, and the spring C3356 is welded to the movable groove opened in the inner wall of the cavity.

[0123] Spring C3356 is located on one side of sliding sleeve 3355 and is sleeved on sliding rod 3357;

[0124] The slide rod 3357 passes through the slide sleeve 3355 and is fixedly connected to both sides of the inner cavity of the insert plate 3351.

[0125] In this embodiment of the invention, when the insert plate 3351 moves out of the fixing block 335, the spring C3356 is pushed back by the force to push the sliding sleeve 3355 to drive the hinge rod 3354 to move. This causes the hinge rod 3354 to push the flip plate 3353 to flip outward, while increasing the contact area with the sleeve B336 and ensuring the stability of the connection.

[0126] Please see Figure 5 and Figure 8 The present invention provides a safety telescopic fence for power engineering, wherein the surface of the pole C339 is rotatably connected to two opposing transmission gears 3393 via an installation component;

[0127] A handle 3391 is welded to one side of the surface of the transmission gear 3393, and the side of the transmission gear 3393 away from the handle 3391 extends into the insert rod C339.

[0128] The insertion rod C339 is internally connected to a T-shaped ground cone 3392;

[0129] The surface of the ground cone 3392 is provided with longitudinally equidistant teeth at the position corresponding to the transmission gear 3393, and the ground cone 3392 is connected to the transmission gear 3393 through the teeth.

[0130] In this embodiment of the invention, while pushing the handle 3391 drives the transmission gear 3393 to rotate, the transmission gear 3393 can push the ground cone 3392 along the insertion rod C339 to a suitable position through its teeth, thereby exposing the ground cone 3392, making it convenient for operators to insert the ground cone 3392 into the ground and enhancing the connection.

[0131] It is worth mentioning that the handle 3391 is fixed to the transmission gear 3393, and the transmission gear 3393 can be driven to rotate synchronously by flipping the handle 3391.

[0132] It should be noted that by reversing the handle 3391, the ground cone 3392 can be retracted into the insertion rod C339, avoiding exposure and damage, and reducing the safety hazards caused by exposure.

[0133] Please see Figure 5 and Figure 9 The present invention provides a safety telescopic fence for power engineering, wherein a handwheel 3382 is rotatably connected to one side of the surface of the pole A338;

[0134] A bevel gear A3383 is welded to one end of the handwheel 3382 inserted into the insert rod A338.

[0135] Bevel gear A3383 is meshed with bevel gear B3384 on one side;

[0136] One end of the bevel gear B3384 is rotatably connected to the insert rod A338, and the other end of the insert rod A338 is screwed into the screw hole on the surface of the insert rod B3381.

[0137] In this embodiment of the invention, rotating the handwheel 3382 drives the bevel gear A3383 to rotate, causing the bevel gear B3384 to push the insertion rod B3381 to a suitable position via the screw B3385, making it convenient for operators to adjust the working angle and length of the insertion rod A338 according to the ground inclination.

[0138] It should be noted that the surface of the insertion rod B3381 has a limiting strip that slides through the inner wall of the insertion rod A338. This design is used to ensure the stability of the insertion rod B3381 during movement and to prevent deflection and slippage.

[0139] Please see Figure 5 , Figure 10 and Figure 11 The present invention provides a safety telescopic fence for power engineering, wherein the fixing component 34 includes a sleeve plate 341 welded to the movable cavity of the connecting plate 337 and located on one side of the insert rod A338, and a knob 342 rotatably connected to the surface of the sleeve plate 341.

[0140] Two opposing transmission wheels A343 are fixedly fitted onto one end of the knob 342 inserted into the sleeve 341.

[0141] The transmission belt 345 is provided on the surface of the transmission wheel A343;

[0142] The transmission belt 345 is inserted into the inner wall of the groove C inside the movable cavity of the connecting plate 337, and a transmission wheel B344 is sleeved on one side of the inner wall.

[0143] A screw C348 is fixedly sleeved inside the transmission wheel B344, and the screw C348 is rotatably connected to the slot C of the connecting plate 337;

[0144] The surface of the screw C348 is screwed with a threaded sleeve B346, and an extrusion plate 347 is welded to one side of the surface of the threaded sleeve B346.

[0145] The side of the extrusion plate 347 facing the pivot of the insertion rod A338 is a concave semi-circular surface, and the semi-circular surface is provided with anti-slip texture.

[0146] It is worth mentioning that, Figure 10 for Figure 5 From the top view, it can be seen that the fixing component 34 is located inside the connecting plate 337 and is located on one side of the plug A338.

[0147] In this embodiment of the invention, rotating the knob 342 drives the transmission wheel A343 to rotate, which in turn drives the screw C348 to rotate via the transmission wheel B344. This controls the screw sleeve B346 to move the extrusion plate 347 along the screw C348 until the semi-circular surface of the extrusion plate 347 abuts against the rotating shaft surface of the insertion rod A338, thus fixing the insertion rod A338 and assisting the operator in reinforcing the installation angle of the insertion rod A338.

[0148] It should be noted that drive wheel A343, drive wheel B344, and drive belt 345 can be gear and chain drives to enhance connectivity and prevent slippage.

[0149] It should be noted that after pushing the insertion rod A338 to flip along the connecting plate 337 to the appropriate position, the insertion rod B3381 is moved to drive the insertion rod C339 into the placement groove on the surface of the sleeve B336, thus completing the storage of the insertion rod A338, further reducing the occupied area and making it convenient for operators to carry and operate.

[0150] Working principle and usage process: While pushing the mounting plate 311 to rotate along the column 1, the mounting plate 311 pulls the slide block 315 along the slide plate 314 to a suitable position via the hinge plate 313. At this time, the slide plate 314 is connected to the slide block 315 by the rotating positioning bolt 316, thus fixing the angle of the mounting plate 311. The plug plate 312 is pulled out from the mounting plate 311 to increase the contact area between the column 1 and the ground. The mounting plate 311 and the plug plate 312 are then connected to the ground simultaneously by external bolts. To enhance connection stability, push sleeve B336 to rotate connecting plate 337 along sleeve A331 to a suitable angle, and rotate knob 333 to move threaded sleeve A334 through fixing block 335 to move insert plate 3351 along screw A332 until spring B3352 abuts against sleeve B336, thus fixing sleeve B336. This assists the operator in adjusting the position of insert rod A338. Push handle 3391 to rotate transmission gear 3393. 3. The ground cone 3392 can be moved along the insertion rod C339 to a suitable position by pushing it with teeth, thus exposing the ground cone 3392 for easy insertion into the ground. Rotating the knob 342 drives the transmission wheel A343 to rotate, which in turn drives the screw C348 to rotate via the transmission wheel B344. This controls the screw sleeve B346 to move the extrusion plate 347 along the screw C348 until the semi-circular surface of the extrusion plate 347 abuts against the rotating shaft surface of the insertion rod A338, completing the insertion of the insertion rod A3392. The fixing of 38 assists the operator in reinforcing the installation angle of the insertion rod A338. While the mounting plate 311 is being retracted into the column 1, the push block 321 is pushed downward to drive the insertion block 323 into the corresponding connecting groove on the surface of the insertion plate 312. At this time, the spring A327 is pushed back by the force to push the lever 326 to flip. The lever 326 pushes the locking block 328 to lock into the fixing groove on the inner wall of the connecting groove of the insertion plate 312, thus completing the fixing of the insertion plate 312, thereby achieving folding and storage and reducing the occupied area.
