Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of power maintenance warning, and in particular to a protective mechanism and a power maintenance warning device. Background Technology
[0002] A power maintenance warning device is a safety warning device used during the maintenance of power facilities. Its purpose is to remind pedestrians and vehicles to pay attention to safety and avoid approaching or touching the power facilities under maintenance.
[0003] During the work process, the staff first moved the guardrails used for maintenance to the maintenance area. The usual warning device is to hang warning signs and light sources on the guardrails to remind pedestrians that power maintenance is being carried out here, so as to ensure the safety of pedestrians and vehicles. After the maintenance is completed, the operator turns off the warning device and moves it out of the maintenance area.
[0004] However, warning signs and lights may not be enough to attract children's attention, especially if they are insensitive to these warnings or ignore them out of curiosity. Warning devices reduce their protection for children, who may inadvertently enter dangerous areas, resulting in injury or even more serious consequences. In addition, guardrails may not be stable enough during operation, and workers may accidentally knock them over or move them, thus threatening the safety of workers. Utility Model Content

[0041] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a protective mechanism. This device includes...
[0042] The early warning unit 400 includes an early warning horn 401; it is used to drive away people who are close to the guardrail, so as to prevent these people from having accidents and being injured, and to protect them.
[0043] The receiving unit 100 includes a receiving box 101; it accommodates the pressing and resetting of the pressing plate 202, and the groove on the receiving box 101 provides space for the pressing plate 202 to be pressed down when someone steps on the pressing plate 202.
[0044] The support unit 200 includes an elastic strip 201 disposed on the receiving box 101, a pressing plate 202 disposed on the elastic strip 201, and an elastic component 203 disposed on the pressing plate 202; and the trigger unit 300 includes a mounting base 301 disposed on the receiving box 101, a gas generating component 302 disposed on the mounting base 301, and a trigger component 303 disposed on the mounting base 301. The elastic strip 201 and the elastic component 203 are used to reset the pressing plate 202 after pressing. The gas generated by the gas generating component 302 is the power source for the operation of the trigger component 303. The pressing down of the pressing plate 202 provides the power source for the gas generating component 302 to generate gas. The mounting base 301 is used to fix and support the movement of the piston 302b, so as to facilitate the delivery of the generated gas to the collection member 303b for storage.
[0045] The elastic component 203 includes a telescopic sleeve 203a disposed on the receiving box 101, a telescopic post 203b disposed on the telescopic sleeve 203a, and a spring 203c disposed on the telescopic post 203b; the telescopic post 203b is disposed on the pressing plate 202. The telescopic post 203b on the elastic component 203 is connected to the pressing plate 202 and is used to reset the pressing plate 202 after it has been stepped on, preventing the pressing plate 202 from getting stuck in the groove of the receiving box 101 after being stepped on.
[0046] The gas generating assembly 302 includes an air inlet 302a mounted on a mounting base 301, a piston 302b mounted on the mounting base 301, a push rod 302c mounted on the piston 302b, a connecting block 302d mounted on the push rod 302c, and a spring 302e mounted on the connecting block 302d. The mounting base 301 has a slot 302f that matches the piston 302b, and adjacent slots 302f are connected by a strip groove 302g. The connecting block 302d in the gas generating assembly 302 connects the pressing plate 202 and the push rod 302c. When the pressing plate 202 sinks, the push rod 302c pushes the piston 302b to move in the slot 302f. According to the principle of a cylinder, the generated gas enters the gas supply pipe 303a along the strip groove 302g, serving as the power source for triggering the operation of the assembly 303.
[0047] During operation, the staff will first fence off the damaged electrical area and hang a warning sign (502d) on the fence. Next, the operator will install a protective mechanism around the fence, away from it. This mechanism is for the protection of unsupervised children or supervised individuals near the electrical repair site, as well as other personnel unrelated to the electrical repair. Then, the staff will connect the wiring on contact plate 303e and contact plate 303g. This wiring has a pre-installed connector and is designed to accommodate… Inside box 101, the circuit of the warning horn 401 is initially disconnected and a terminal is reserved. When the staff sets up the guardrail to carry out power maintenance work, they connect the terminal on this circuit to the terminal on the circuit of the warning horn 401 and turn on the power. This power source is a storage battery, which is hidden inside the box 101. The contact and non-contact of contact plate 303e and contact plate 303g realize the opening and closing of the circuit of the warning horn 401, which is equivalent to the switch for the warning horn 401 to work. Finally, the operator enters the guardrail to carry out the work.
[0048] When children or other personnel unrelated to maintenance enter the perimeter of the fence, they will step on the press plate 202 on the containment box 101. The downward movement of the press plate 202, through the push rod 302c connected to the connecting block 302d and the press plate 202, pushes the piston 302b to move in the slot 302f. Air enters the slot 302f through the air inlet 302a. The gas generated by the principle of cylinder gas generation enters the air supply pipe 303a along the strip groove 302g, serving as the power source for the trigger component 303. The operation of the trigger component 303 closes the circuit of the warning horn 401, and the warning horn 401 begins to drive away personnel unrelated to power maintenance. After hearing the warning horn 401 broadcast, the staff will also verbally drive away these unrelated personnel, thereby protecting children or other irrelevant personnel from entering the fence and causing injury or even more serious consequences. Example
[0049] Reference Figures 1-4 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the triggering component 303 includes an air supply pipe 303a disposed on the mounting base 301, a collection component 303b disposed on the air supply pipe 303a, an airbag 303c disposed on the collection component 303b, and a lever 303d disposed at one end of the airbag 303c. The air supply pipe 303a delivers the gas generated in the mounting base 301 to the collection component 303b for storage, ensuring that the airbag 303c is expanded each time the pressing plate 202 is stepped on and pressed down, causing the contact plate 1 303e and the contact plate 2 303g to come into contact, thereby closing the circuit of the warning horn 401.
[0050] Compared to Embodiment 1, in this further embodiment, one end of the lever 303d is disposed on a first contact plate 303e, a support block 303f is disposed on the first contact plate 303e, and a second contact plate 303g is disposed on one side of the first contact plate 303e. The lever 303d swings on the support block 303f, causing contact between the first contact plate 303e and the second contact plate 303g. The contact and closure of the first contact plate 303e and the second contact plate 303g realize the closing and opening of the warning horn 401 circuit.
[0051] During use, when a person steps on the press plate 202, the downward movement of the press plate 202 causes the gas generating component 302 to produce gas. The generated gas flows along the gas delivery pipe 303a into the collection component 303b. The gas in the collection component 303b causes the airbag 303c to inflate. The inflated airbag 303c then drives the lever 303d to move on the support block 303f, causing contact plates 303e and 303g at one end of the lever 303d to come into contact. Contact plates 303e and 303g are made of conductive material, enabling... When the warning horn 401 closes, the inflating airbag 303c causes the lever 303d to reach an angle on the support block 303f that is sufficient for the contact time between contact plate 303e and contact plate 303g to allow the warning horn 401 to complete its broadcast. After the warning horn 401 drives people away, the pressing plate 202 resets under the action of the elastic component 203 and the elastic strip 201. Then, the gas in the airbag 303c begins to decrease, and contact plate 303e and contact plate 303g become non-contact, thus closing the circuit of the warning horn 401 and stopping the broadcast. Timely warnings can reduce potential accidental injuries caused by personnel entering dangerous areas, thus protecting personnel.
[0052] The remaining structure is the same as that in Example 1. Example
[0053] Reference Figures 1-6 This is the third embodiment of the present invention, which differs from the second embodiment in that: a power maintenance warning device includes,
[0054] The protective unit 500 includes a support frame 501 disposed on one side of the receiving box 101, and a protective component 502 disposed on the support frame 501; and the fixing unit 600 includes a fixing base 601 disposed on the support frame 501, and a fixing component 602 disposed on the fixing base 601. Both the protective component 502 and the fixing component 602 are used to reinforce the installation and structure of the guardrail, providing safety for workers during operation.
[0055] Compared to Embodiment 2, the protective component 502 further includes a connecting base 502a disposed on the support frame 501, a fixing frame 502b disposed on the connecting base 502a, and a protective net 502c disposed on the fixing frame 502b. A support base 503 is disposed on the support frame 501, and a mounting hole 504 is disposed on the support base 503. A warning sign 502d is disposed on the protective net 502c. The connecting base 502a and the mounting hole 504 enable the installation of the guardrail in the work area. The fixing frame 502b is used to combine the protective net 502c to form an independent protective unit 500, which is then installed on the support frame 501 to achieve the protective function of the guardrail. The warning sign 502d on the guardrail creates a visual warning impact, warning unauthorized personnel to stay away from the power maintenance work area.
[0056] The fixing component 602 includes a fixing rod 602a movably mounted on a fixing base 601, and a fixing sleeve 602b mounted on the fixing rod 602a. The fixing base 601 has a straight groove 602c, one end of the fixing rod 602a has a bolt 602d, and the fixing sleeve 602b has a bolt 602e. The fixing rod 602a can extend and retract within the fixing sleeve 602b, allowing workers to install the fixing plate into the straight groove 602c on the fixing base 601 using bolt 602d, and then fix the fixing plate to the fixing sleeve 602b using bolt 602e, thus securing the support frames 501 and enhancing the structural stability of the guardrail.
[0057] During use, the staff first installs the guardrail at the location of the power outage requiring maintenance. The independent unit formed by the fixed frame 502b and the protective net 502c is then installed on the support frame 501 to achieve the guardrail's protective function. Next, the fixed plate is extended or retracted within the fixed sleeve 602b, adjusting the installation distance between the fixed plate and the support frame 501. Bolt 602d is used to fix the fixed plate to the fixed base 601, and bolt 602e is used to fix the fixed plate to the fixed sleeve 602b, consolidating the stability of the fixed plate on the support frame 501. This strengthens the structural stability of the guardrail, improves the protection for the staff, and solves the problem that instability of the guardrail during operation could threaten the safety of staff performing maintenance tasks.
[0058] The remaining structure is the same as that in Example 2.
