Description

Technical Field

[0001] The present invention relates to the technical field of maintenance fences, and in particular to an intelligent maintenance fence and an operating method thereof. Background Art

[0002] Before carrying out equipment maintenance or other work in the substation, the substation operation and maintenance personnel need to isolate the live equipment outside the maintenance area with red curtains or other items, and use mobile fences to enclose the working range of personnel entering the maintenance area to ensure the personal safety of construction personnel and the safety of operating equipment and avoid accidents. Since the arrangement of safety measures and the demarcation of the scope are completely done manually, and the fence equipment needs to be brought from the tool room to arrange the working range, there are the following problems and shortcomings:

[0003] 1) Outdoor mobile fences need to be manually transported from the tool room and temporarily deployed on site, which results in low efficiency, heavy workload, inaccurate range demarcation or missed ranges, potential safety hazards, and reduced work efficiency.

[0004] 2) The indoor red cloth curtain fence isolates the operating equipment area, which has unreliable locking and lacks forced closure measures, and is prone to automatic falling off or accidental operation.

[0005] 3) There is a lack of single-point forced isolation and locking measures for secondary equipment (pressure plates, circuit breakers, handles, etc.), and there is a risk of secondary isolation equipment being accidentally activated.

[0006] In order to improve the quality and efficiency of substation maintenance operations, a safe and reliable intelligent maintenance fence is very necessary.

[0007] In the prior art, the isolation measures for the maintenance of existing outdoor high-voltage equipment mostly adopt a fence mode: when performing maintenance work on outdoor high-voltage equipment, an ordinary fully enclosed barrier fence is installed around the work site, and a "Enter and exit from here" sign is set, and an appropriate number of "Stop, high voltage danger!" signs are hung on the fence. This mode requires the fence poles to be carried back and forth, and there are problems such as low work efficiency and heavy workload. For the isolation of indoor equipment and secondary equipment in safety measures, adhesive tapes, hanging red curtains, etc. are mostly used for deployment, which are unreliable, easy to fall off, and lack mandatory locking management methods. Therefore, we provide an intelligent maintenance fence and operation method. Summary of the invention

[0046] An intelligent maintenance fence and an operating method provided by the present invention are now described.

[0047] Example 1

[0048] like Figure 1-4 As shown, the present invention provides a technical solution: an intelligent maintenance fence, comprising: a closed shell 1, a waterproof breathable valve 2 is arranged on one side of the closed shell 1, a waterproof joint 3 is arranged at the bottom of the closed shell 1 on the same side as the waterproof breathable valve 2, an electric telescopic rod 4 is arranged in the closed shell 1, a bottom shell 5 is arranged at one end of the electric telescopic rod 4, and a heating dehumidifier 6 is arranged in the bottom shell 5;

[0049] The outer surface of the electric telescopic rod 4 is provided with a quick-install mechanism 7, which includes a clamp 71, one end of which is provided with a rotating shaft connection block 72, one end of which is away from the rotating shaft connection block 72, and a rotating shaft screw 73, one end of which is provided with a handle nut 74;

[0050] The two ends of the rotating shaft connecting block 72 are respectively fixed to one end of the clamp 71, the outer surface of the rotating shaft screw 73 is limitedly nested and docked at the end of the clamp 71 away from the rotating shaft connecting block 72, and one end of the handle nut 74 is docked at one end of the rotating shaft screw 73;

[0051] One end of the waterproof breathable valve 2 is installed on one side of the sealed shell 1, one end of the waterproof joint 3 is connected to the sealed shell 1 on the same side of the waterproof breathable valve 2, the sealed shell 1 is nested on the outer surface of the electric telescopic rod 4, one end of the electric telescopic rod 4 is installed on the bottom shell 5, and the outer surface of the heating dehumidifier 6 is nested on the bottom shell 5.

[0052] In this embodiment, on the basis of the substation anti-error host, the maintenance isolation and anti-error module is expanded to realize the generation of maintenance operation scope and secondary locking tasks through maintenance equipment selection or intelligent analysis of safety measures; intelligent fence poles are deployed at the outdoor equipment site, and the anti-error host is connected through a communication controller or a mobile terminal. The control instructions issued by the communication controller or the mobile terminal can be received for automatic lifting and lowering, and the secondary equipment can be forcibly locked through the mobile terminal, so that there is no need for personnel to define the safety range and arrange fence poles; a magnetically lockable telescopic fence is used to isolate the indoor maintenance area, and special locking accessories are used for forced locking of secondary pressure plates and circuit breakers, so as to realize all-round isolation and control of points, lines and surfaces for maintenance operations, improve the safety level of substation maintenance operations, improve work efficiency and reduce operating costs. More specifically, the electric intelligent fence pole consists of four parts: a closed shell 1, an electric telescopic rod 4, a heating dehumidifier 6 and a quick-install mechanism 7.

[0053] The electric telescopic rod 4 and the heating dehumidifier 6 are in the sealed shell 1. The heating dehumidifier 6 ensures that the motor environment is dry and the motor is not easily damaged. The telescopic part of the electric telescopic rod 4 is waterproof, so the upper two sections can be placed outside the sealed shell 1 to ensure static and dynamic separation and facilitate waterproofing; the sealed shell 1 is made of sheet metal to reduce weight; the waterproof breathable valve 2 is used to ensure the pressure balance inside and outside the sealed cavity; the waterproof connector 3 is used for internal cable routing, and EPDM strips are installed on the clamp 71 (to increase friction and increase the force area to avoid damage to the motor telescopic rod); loosen the handle nut 74 and move the shaft screw 73 out to remove the warning belt quick-release assembly.

[0054] Example 2

[0055] like Figure 1-5 As shown, the present invention provides a technical solution: an intelligent maintenance fence operation method, comprising the following steps:

[0056] S1, maintenance task generation;

[0057] S2, outdoor intelligent fence and indoor maintenance area isolation;

[0058] S3, secondary equipment isolation and locking;

[0059] S4. Dismantling of isolation devices;

[0060] Step S1: During the maintenance task generation, a new maintenance task is created on the error-prevention host. Through intelligent analysis of safety measures, or by directly selecting maintenance equipment on the wiring diagram, the system automatically determines the maintenance area and generates a secondary equipment locking task.

[0061] Step S2, outdoor smart fence and indoor maintenance area isolation:

[0062] S2.1. The anti-error host identifies the intelligent fence pole associated with the maintenance area according to the maintenance area, and sends the safety measures arrangement instruction through the anti-error key or directly to the communication controller;

[0063] S2.2. The smart fence pole associated with the work area automatically rises after receiving the control command. The staff pulls out the safety belt from the fence pole and connects it to the fence pole of the work area to complete the safety belt arrangement.

[0064] Step S3: In the isolation and locking of the secondary equipment, for the locking tasks including the indoor maintenance area and the secondary equipment, the "anti-mistaken key + locking accessories + isolation lock" mode is used for forced locking;

[0065] Step S4, isolating device being removed:

[0066] S4.1. After the operation is completed, the maintenance task is completed on the error-proof host, and the system automatically issues a safety measure removal instruction;

[0067] S4.2, after receiving the command, the intelligent fence pole automatically descends and completes the removal of the security measures;

[0068] S4.3. The staff removes the connected safety belts, removes the locking accessories of the secondary equipment, and puts them back into the maintenance box.

[0069] In this embodiment, in step S1, the staff creates a new maintenance task on the anti-error host, and through intelligent analysis of safety measures, or directly selects the equipment to be repaired on the wiring diagram, the system will automatically determine the maintenance area and generate the locking task of the secondary equipment. Then, in step S2, in order to achieve the isolation of the outdoor smart fence and the indoor maintenance area, the anti-error host identifies the smart fence rod associated with it according to the determined maintenance area, and issues the security arrangement instruction through the anti-error key or directly to the communication controller. After receiving the instruction, the smart fence rod will automatically rise, and the staff will extract the security belt from the fence rod, connect the fence rod of the operation area, and complete the fence arrangement. In step S3, for the locking task of the indoor maintenance area and the secondary equipment, the "anti-error key + locking accessories + isolation lock" mode is used for forced locking to ensure the safe isolation of the equipment. Finally, in step S4, after the operation is completed, the staff ends the maintenance task on the anti-error host, and the system automatically issues the security removal instruction. The smart fence pole automatically descends after receiving the command. The staff then removes the connected safety belts, removes the locking accessories of the secondary equipment, and puts them back into the maintenance box, thus completing the operation of the entire smart maintenance fence.

[0070] The present invention,

[0071] In actual use, the intelligent maintenance fence is mainly composed of a closed shell 1, an electric telescopic rod 4, a heating dehumidifier 6 and a quick-install mechanism 7. First, a waterproof breathable valve 2 is installed on one side of the closed shell 1 to maintain the balance of internal and external air pressures, and a waterproof joint 3 is provided on the same side of the bottom to facilitate the safe guidance of the internal cables. One end of the electric telescopic rod 4 is connected to the bottom shell 5, and a heating dehumidifier 6 is embedded in the bottom shell 5 to ensure the dryness of the motor working environment and prevent damage caused by moisture. The outer surface of the electric telescopic rod 4 is equipped with a quick-install mechanism 7 for easy installation and disassembly. The quick-install mechanism 7 includes a clamp 71, a shaft connection block 72, a shaft screw 73 and a handle nut 74. The clamp 71 is fixed at one end through the shaft connection block 72, and the other end is connected to the handle nut 74 through the shaft screw 73 to ensure the stable installation of the fence. In order to meet different installation requirements, the clamp 71 is also equipped with an EPDM strip to increase friction and protect the electric telescopic rod 4 from damage. The design of the electric telescopic rod 4 enables the telescopic portion thereof to have excellent waterproof capabilities, ensuring flexibility and waterproofness during operation.

[0072] For the operation method of the intelligent maintenance fence, first in step S1, the staff uses the anti-error host to create a new maintenance task. Through intelligent analysis or selecting equipment on the wiring diagram, the system can automatically identify the maintenance area and generate related secondary equipment locking tasks. Next, step S2 involves the isolation of the outdoor intelligent fence and the indoor maintenance area. The anti-error host identifies the required intelligent fence pole according to the task, and issues a layout instruction through the anti-error key or communication controller. The intelligent fence pole automatically rises according to the instruction, and the staff extracts the security belt from the fence pole and connects it to the fence pole in the operation area to complete the layout. In step S3, for the locking task of the indoor maintenance area and secondary equipment, the "anti-error key + locking accessories + isolation lock" mode is used for forced locking to ensure the safe isolation of the equipment. The last step S4 is the removal of the isolation device. When the operation is completed, the staff ends the maintenance task on the anti-error host, and the system automatically issues the security removal instruction. After receiving the instruction, the intelligent fence pole automatically lands, and the staff then removes the security belt and the locking accessories of the secondary equipment, and finally puts them neatly back into the maintenance box, successfully completing the entire operation process. This systematic and intelligent operation process greatly improves the safety and efficiency of maintenance operations.
