Description

Technical Field

[0001] This invention relates to the field of substation safety measures technology, specifically to a fast-retractable fence for substation safety measures. Background Technology

[0002] Before operation, substation high-voltage equipment needs to be isolated from non-operational equipment by installing barriers. Currently, substation barriers mainly use pole-type and bracket-type umbrella-type fencing for fixed isolation. Installing safety measures requires transporting a large number of these pole-type and bracket-type fencing poles, which are numerous, bulky, and inconvenient to move. Installing nylon rope fencing requires significant time to untangle knots and clean the front and back of the fencing. After work, the fencing poles and fencing need to be collected, organized, and placed in a designated location in the safety tool shed. The back-and-forth transport and collection of fencing poles and fencing is physically demanding and time-consuming, increasing the time required for safety measure installation and removal, and extending power outage and restoration time, significantly reducing user satisfaction.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a telescopic fence as a safety measure for substations.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a retractable fence for substation safety measures, comprising:

[0006] The telescopic pole includes a first sleeve pole pre-embedded in the ground, one or more second sleeve poles adjustablely disposed within the first sleeve pole, and a third sleeve pole disposed inside the second sleeve pole at the top;

[0007] A telescopic component, disposed inside the telescopic rod, is used to drive the telescopic rod to extend or retract;

[0008] The positioning component includes a locking element disposed on the third sleeve rod and a fastener disposed on the first sleeve rod and cooperating with the locking element.

[0009] Furthermore, the top of the third sleeve is provided with a top plate, and the telescopic component is a first spring with its bottom end set on the first sleeve and its top end abutting against the top plate;

[0010] When the third and second sets of rods are housed inside the first set of rods, the first spring is under compression.

[0011] When the third and second sets of rods are fully extended, the first spring is in an uncompressed state.

[0012] Furthermore, it also includes a protective mechanism, which includes a support rod disposed on the top plate and a dust cover disposed on the support rod, wherein the diameter of the dust cover is not less than the diameter of the first sleeve rod.

[0013] Furthermore, the locking element includes locking blocks disposed on both sides of the support rod and second springs disposed at both ends on the support rod and the locking blocks respectively. The end of the locking block away from the second spring is configured as an arc-shaped structure, and the fastener is an arc-shaped groove disposed in the first sleeve rod and adapted to the locking block.

[0014] Furthermore, the bottom outer sides of the first sleeve rod and the second sleeve rod are respectively provided with blocking blocks.

[0015] Furthermore, the top plate is provided with a guardrail and a torsion spring inside, the outer end of the guardrail is provided with a clip, and the other side of the top plate is provided with a slot.

[0016] Furthermore, it also includes a power mechanism, which includes a power component disposed outside the telescopic rod, a stop block disposed at the top of the telescopic component, a first traction rope and a second traction rope with one end cooperating with the power component, the other end of the first traction rope being connected to the stop block, one end of the second traction rope being disposed on the stop block, and the other end of the second traction rope being provided with two strands, which are respectively connected to the locking block.

The main controller is signal-connected to the smart terminal. The main controller is used to control the movement of the power component, and the power supply is used to provide power to the main controller and the power component.

[0019] Furthermore, the main controller is also equipped with a touch screen for displaying the status of each telescopic rod.

[0020] Furthermore, the power component is a motor, and the output shaft of the power component is provided with a winding wheel for winding the first traction rope. The output shaft is provided with a positioning groove, and an arc block connected by a third spring is provided in the positioning groove. The winding wheel is provided with an arc groove that cooperates with the arc block.

[0021] Compared with existing technologies, the present invention has the following advantages: By setting up telescopic poles and telescopic components, and pre-burying the first set of poles underground, the telescopic poles are fully retracted when not in use. At this time, the fence is pre-buried underground, eliminating the need for disassembly, transportation, and recycling. When in use, only the locking mechanism needs to be released to fully release the telescopic poles. Afterward, only a fence net needs to be hung on the outside of multiple telescopic poles to achieve the enclosure function. This reduces the setup time when using the fence, improves the efficiency of safety measures, and thus reduces power outage time. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-6 .

[0034] The present invention relates to a retractable safety barrier for substations, comprising:

[0035] The telescopic pole 1 includes a first sleeve pole 11 pre-embedded in the ground, one or more second sleeve poles 12 adjustablely disposed within the first sleeve pole 11, and a third sleeve pole 13 disposed inside the second sleeve pole 12 at the top.

[0036] Telescopic component 2 is disposed inside the telescopic rod 1 and is used to drive the telescopic rod 1 to extend or retract;

[0037] The positioning component 3 includes a locking component 31 disposed on the third sleeve rod 13 and a fastener 32 disposed on the first sleeve rod 11 and cooperating with the locking component 31.

[0038] When not in use, by pressing down the first sleeve rod 11 and the second sleeve rod 12, the first sleeve rod 11 and the second sleeve rod 12 compress the telescopic member 2 until the first sleeve rod 11 and the second sleeve rod 12 are located inside the third sleeve rod 13, and the first sleeve rod 11 and the second sleeve rod 12 are positioned by the cooperation of the locking piece 31 and the fastener 32. At this time, the telescopic rod 1 is completely underground.

[0039] In use, by pulling the first telescopic rod 11 upward, the engagement of the locking piece 31 and the fastener 32 is released, and the telescopic piece 2 is reset, thereby causing the first telescopic rod 11 and the second telescopic rod 12 to extend. Then, a fence net is hung between the multiple telescopic rods 1 to achieve the function of fence protection.

[0040] In one embodiment, the top of the third sleeve rod 13 is provided with a top plate 14, and the telescopic member 2 is a first spring 21 with its bottom end set on the first sleeve rod 11 and its top end abutting against the top plate 14;

[0041] When the third sleeve rod 13 and the second sleeve rod 12 are housed inside the first sleeve rod 11, the first spring 21 is under compression.

[0042] When the third set of rods 13 and the second set of rods 12 are fully extended, the first spring 21 is in an uncompressed state.

[0043] With this design, by setting up the top plate 14 and the first spring 21, when stored, the top plate 14 presses the first spring 21. After the engagement of the latch 31 and the fastener 32 is released, the second sleeve rod 12 and the third sleeve rod 13 can be unfolded under the reset action of the first spring 21.

[0044] In one embodiment, a protective mechanism 4 is also included. The protective mechanism 4 includes a support rod 41 disposed on the top plate 14 and a dust cover 42 disposed on the support rod 41. The diameter of the dust cover 42 is not less than the diameter of the first sleeve rod 11. This design, by providing the dust cover 42, can provide dust and water protection for the telescopic rod 1, preventing dust or water from entering the telescopic rod 1 when it is not in use and affecting its normal use.

[0045] Preferably, the support rod 41 is a threaded rod.

[0046] Preferably, the dust cover 42 has a notch, and a pull ring is rotatably disposed within the notch. This design allows the dust cover 42 to be easily pulled upwards by the pull ring, thereby facilitating the release of the engagement between the clip 31 and the fastener 32. The notch also facilitates the placement of the pull ring.

[0047] In one embodiment, the locking member 31 includes locking blocks 311 disposed on both sides of the support rod 41 and a second spring 312 disposed at both ends on the support rod 41 and the locking blocks 311 respectively. The end of the locking block 311 away from the second spring 312 is configured as an arc-shaped structure. The fastener 32 is an arc-shaped groove 321 disposed in the first sleeve rod 11 and adapted to the locking block 311. This design, by setting the locking block 311 and the second spring 312, and setting the end of the locking block 311 away from the second spring 312 as an arc-shaped structure, facilitates the engagement between the locking block 311 and the arc-shaped groove 321. Furthermore, under the action of external force, it is easy to disengage the engagement between the locking block 311 and the arc-shaped groove 321, thus facilitating the use of the telescopic rod 1.

[0048] In one embodiment, blocking blocks 15 are respectively provided on the outer bottom of the first sleeve rod 11 and the second sleeve rod 12. This design, by providing blocking blocks 15, can prevent the first sleeve rod 11 and the second sleeve rod 12 from falling off, thereby ensuring the normal use of the telescopic rod 1.

[0049] In one embodiment, the top plate 14 is internally provided with a guardrail 5 and a torsion spring 51. A locking head 52 is provided at the outer end of the guardrail 5, and a locking groove 53 is provided on the other side of the top plate 14. The guardrail 5 is a red reflective strip. This design, by providing the guardrail 5 and torsion spring 51 internally, and by providing the locking head 52 and locking groove 53, allows the red reflective guardrail 5 to provide a warning effect during use by engaging the locking head 52 in the locking groove 53 on the adjacent telescopic rod 1.

[0050] In one embodiment, a power mechanism 6 is also included. The power mechanism 6 includes a power component 61 disposed outside the telescopic rod 1, a stop block 62 disposed at the top of the telescopic component 2, a first traction rope 63 and a second traction rope 64, one end of which cooperates with the power component 61. The other end of the first traction rope 63 is connected to the stop block 62. One end of the second traction rope 64 is disposed on the stop block 62, and the other end of the second traction rope 64 is provided with two strands, which are respectively connected to the locking block 311. With this design, by setting the power component 61, it is easy to release or retract the first traction rope 63 and the second traction rope 64. By setting the stop block 62, it is possible to realize the storage or release of the first sleeve rod 11 and the second sleeve rod 12 during the release or retraction of the first traction rope 63.

[0051] In one embodiment, a guide block 111 for changing the direction of the first traction rope 63 is provided at the bottom of the first sleeve rod 11. This design allows the direction of the first traction rope 63 to be changed by providing the guide block 111, thereby enabling the first traction rope 63 to drive the stop block to move vertically, and facilitating the power component 61 to release or retract the first traction rope 63.

[0052] In one embodiment, a control mechanism 7 for providing power to the power component 61 is also included. The control mechanism 7 includes a main controller, a power supply, and a smart terminal. The main controller is signal-connected to the smart terminal. The main controller is used to control the movement of the power component 61, and the power supply is used to provide power to the main controller and the power component 61. With this design, by setting up a main controller and a smart terminal, in use, the main controller is connected to the smart terminal via a signal. First, the motor winds up the first traction rope 63. At this time, under the action of the second traction rope 64, the engagement between the locking piece 31 and the fastener 32 is released. Then, the motor quickly releases the first traction rope 63. Under the action of the first spring 21, the second sleeve rod 12 and the first sleeve rod 11 pop out.

[0053] In one embodiment, the power component 61 is a motor, and the output shaft 611 of the power component 61 is provided with a winding wheel 612 for winding the first traction rope 63. The output shaft 611 is provided with a positioning groove 613, and an arc block 614 connected by a third spring 617 is provided in the positioning groove 613. The winding wheel 612 is provided with an arc groove 615 that cooperates with the arc block. With this design, when the telescopic rod 1 needs to be released, the motor winds up the first traction rope 63, and the locking piece 31 in the positioning piece 3 limits the second traction rope 64, so that the second traction rope 64 can only be partially wound up, and the first traction rope 63 and the second traction rope 64 cannot be wound up any further. At this time, when the motor winds up the first traction rope 63 again, the arc block 614 disengages from the arc groove 615, that is, the winding wheel 612 disengages from the motor. Under the action of the first spring 21, the winding wheel 612 quickly reverses to release the first traction rope 63. Under the action of inertia, the locking piece 311 punches out of the arc groove 321 and realizes the release of the first sleeve and the second sleeve, thus completing the release of the telescopic rod 1.

[0054] Preferably, the output shaft 611 is provided with limiting blocks 616 on both sides of the take-up reel 612 for limiting the take-up reel 612. This design prevents the take-up reel 612 from falling off the output shaft 611.

[0055] In one embodiment, the main controller is further provided with a touch screen, which communicates with the main controller using the ModBus communication protocol, and the touch screen is used to display the status of each telescopic rod 1.

[0056] The main controller MCU uses an STM32F407 processor. The main controller is connected to an ESP8266 WiFi serial port module. The main controller communicates with the touch screen through serial port 1. The main controller and the touch screen use the ModBus communication protocol. The touch screen displays the status of each pre-buried point telescopic fence. Users can send control information to the main controller through the touch screen to control the telescopic fence 1 at each pre-buried point to rise or fall.

[0057] The main controller is connected to the external WiFi serial port module via serial port 2 and connects to the smart terminal device via WiFi. It receives control information sent by the smart terminal and controls the telescopic rod 1 at each pre-embedded point to rise or fall.

[0058] The main controller sends forward and reverse commands to the motor via serial port 3 and RS485 interface using parallel communication via 485 bus, thereby controlling the motor to rotate forward and reverse, thus driving the telescopic rod 1 to rise or fall.

[0059] When the main controller is working normally, LED0 flashes; when the main controller communicates normally with the touchscreen and smart terminal, LED1 flashes. The buttons on the main controller can simultaneously control the forward and reverse rotation of all motors. Pressing Key_0 controls all motors to rotate forward, causing all fence posts to rise. Pressing Key_1 controls all motors to rotate in reverse, causing all fence posts to fall. The program download port is used to download programs to the main controller, and the power supply port is used to supply power to the main controller.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
