[0030] Please refer to Figure 1 , Figure 2 , Figure 3In one embodiment, the present application provides a maintenance and protection device for electric power operation and maintenance management, including a base plate 1, a plurality of universal wheels 2 are arranged at the bottom of the base plate 1, a fixed plate 3 is arranged on the base plate 1, a connecting plate 4 is rotatably connected to one side of the fixed plate 3, a protective plate 5 is rotatably connected to the connecting plate 4, a stabilizing component 6 and a positioning component 7 are slidably arranged in the protective plate 5, the positioning component 7 is used to limit the position of the stabilizing component 6, a clamping component 8 for limiting the protective plate 5 is arranged on the base plate 1, and the clamping component 8 can slide relatively on the base plate 1.

[0031] It can be understood that the use of the fixed plate 3, the connecting plate 4 and the protective plate 5 can play a role of isolation and protection, effectively preventing people from entering the maintenance site. The connecting plate 4 and the fixed plate 3 are rotatably connected, and the connecting plate 4 and the protective plate 5 are rotatably connected, so that the device can change the placement state according to the on-site situation and is suitable for situations with changing environments. The universal wheel 2 is provided to facilitate the movement of the entire device. At the same time, the clamping component 8 provided on the base plate 1 can effectively ensure that the connecting plate 4 and the protective plate 5 will not be detached from the base plate 1 due to bumps during the movement of the device, thereby reducing the occurrence of accidents during the movement. Furthermore, by providing a stabilizing component 6 and a positioning component 7, the protective plate 5 can be detached from the base plate 1 and firmly contact the ground, thereby improving the reliability of the device.

[0032] For details, please refer to Figure 3 , Figure 5 , Figure 8 , Fig. 9 , Fig.10 On the basis of the above embodiment, the stabilizing component 6 includes a sliding plate 601, a first support plate 602, a second support plate 603, a guide rod 604, a pressure plate 605 and a first spring 606. A groove adapted to the positioning component 7 is provided on one side of the sliding plate 601. The first support plate 602 is rotatably connected to both sides of the sliding plate 601. The guide rod 604 and the second support plate 603 are provided inside the first support plate 602. The second support plate 603 can slide relatively on the first support plate 602, and a stepped groove is provided on the second support plate 603. Two pressure plates 605 are provided inside the stepped groove. The two pressure plates 605 are slidably provided on the guide rod 604, and a first spring 606 is connected between the two pressure plates 605.

[0033] It can be understood that the stepped groove is a first stepped groove and a second stepped groove. When the pressing plate 605 is in the first stepped groove, the second supporting plate 603 is in a contracted state (refer to Figure 5 ), that is, when the second support plate 603 is retracted into the first support plate 602 and the pressing plate 605 is in the second stepped groove, the second support plate 603 is in an extended state (refer to Fig. 9), through the above arrangement, the extended second support plate 603 can be limited, and the second support plate 603 can be used to further stabilize the placement of the device.

[0034] For details, please refer to Figure 6 , Figure 7 On the basis of the above embodiment, the positioning assembly 7 includes a clamping rod 701 and a second spring 702, the clamping rod 701 is slidably connected to the sliding plate 601, and both ends of the clamping rod 701 are connected to the groove, one end of the second spring 702 is connected to the clamping rod 701, and the other end of the second spring 702 is connected to the sliding plate 601;

[0035] It can be understood that two grooves are provided on the sliding plate 601 , and the two grooves are adapted to the two ends of the clamping rod 701 , and the extended state and the retracted state of the sliding plate 601 can be effectively limited by the clamping rod 701 entering the grooves.

[0036] For details, please refer to Figure 1 , Figure 3 , Figure 4 On the basis of the above embodiment, the clamping assembly 8 includes a first wedge block 801, a third spring 802 and a pressure rod 803. A slide groove is provided on the bottom plate 1, and the first wedge block 801 and the third spring 802 are provided in the slide groove. One end of the third spring 802 is connected to the first wedge block 801, and the other end of the third spring 802 is connected to the bottom of the slide groove. One end of the first wedge block 801 is connected to the pressure rod 803. It can be understood that by setting the clamping assembly 8, the connecting plate 4 and the protective plate 5 can be limited to avoid separation from the bottom plate 1 during movement.

[0037] For details, please refer to Figure 1 , Figure 3 , Figure 4 On the basis of the above embodiment, it also includes a limit component 9, which is used to limit the clamping component 8. The limit component 9 includes a pull rod 901, a fourth spring 902 and a second wedge block 903. The pull rod 901 is slidably connected to the base plate 1, one end of the pull rod 901 is connected to the second wedge block 903, one end of the fourth spring 902 is connected to the wedge block, and the other end of the fourth spring 902 is connected to the base plate 1. It can be understood that by setting the limit component 9, the clamped parts can be unlocked without manually pressing or stepping on the pressure rod 803 all the time.

[0038] For details, please refer to Figure 1 , Figure 2 On the basis of the above embodiment, it also includes a handle 10. The handle 10 is provided on the base plate 1. The handle 10 is used to assist the user in pushing. It can be understood that the handle 10 is provided to facilitate the user to move the device through the handle 10.

[0039] Specifically, on the basis of the above embodiment, it also includes brake pads (not shown in the figure), and several universal wheels 2 are rotatably connected with brake pads. It can be understood that by providing brake pads, the stability of the device can be provided by increasing friction when the device is stationary, thereby preventing movement caused by factors such as wind.

[0040] In summary, when a maintenance protection device for power operation and maintenance management is used, the device is moved to a specified position by means of the handle 10, and the pressure rod 803 is manually pressed, so that the first wedge block 801 moves toward the inside of the slide slot, and the third spring 802 is in a compressed state. When the pressure rod 803 passes through the second wedge block 903 and the pressure rod 803 is located at the bottom of the second wedge block 903, the user can manually pull the protection plate 5 to separate the connecting plate 4 from the protection plate 5 from the bottom plate 1, and then pull the pull rod 901, so that the sliding plate 601 separates from the protection plate 5 according to its own gravity and contacts the ground. When the pull rod 901 is released, one end of the pull rod 901 is just stuck in the sliding plate 601 to limit the sliding plate 601. The extension of the sliding plate 601 makes up for the distance between the bottom of the protective plate 5 and the bottom of the universal wheel 2. At this time, the first support plate 602 is rotated, and then the two pressure plates 605 are pressed with fingers to compress the first spring 606. The other hand pulls the second support plate 603, and then the two pressure plates 605 are released. After the first spring 606 is reset, it just blocks the second support plate 603. By using the sliding plate 601, the first support plate 602 and the second support plate 60 3 provides a stabilizing effect for the protective plate 5 to contact the ground, thereby improving the stability of the device. Furthermore, since the connecting plate 4 and the fixing plate 3 are rotatably connected, and the connecting plate 4 and the protective plate 5 are rotatably connected, the connecting plate 4 and the protective plate 5 can be flexibly rotated, and the rotation angle can be changed according to the actual situation on site, which can be applied to a variety of environments or scenes. When recovery is required, the two pressing plates 605 are manually pressed and the first spring 606 is compressed, so that the second support plate 603 is fully extended into the first support plate 602, and then the first support plate 602 is rotated in the opposite direction and connected to the sliding plate 603. The sliding plate 601 contacts the plate 601, and the pull rod 901 is pulled to store the sliding plate 601 into the protective plate 5. Then the protective plate 5 and the connecting plate 4 are moved in the direction close to the fixed plate 3 until the connecting plate 4 and the protective plate 5 are placed on the bottom plate 1. At this time, the pull rod 901 is pulled to move the second wedge block 903 in the compression direction of the fourth spring 902. When the second wedge block 903 no longer clamps the pressure rod 803, the first wedge block 801 is reset under the action of the third spring 802, and the protective plate 5 is limited. This can effectively prevent the connecting plate 4 and the protective plate 5 from detaching from the bottom plate 1 during the movement.
