[0002] A substation is a place for changing voltage, and it is necessary to judge whether there is any abnormality through daily inspection and maintenance; most of the existing inspection and maintenance are carried out manually. Equipment operation and maintenance personnel need to carry a lot of necessary inspection tools to conduct inspections every day, such as common tools like electric test pens and screwdrivers, as well as record sheets for recording maintenance situations.

[0003] The Chinese utility model patent with the publication number CN216803391U discloses a substation inspection and maintenance auxiliary device. A protective cover for preventing tools from falling from the top opening is hinged to the side of the box body through a hinge, and a lighting lamp with an adjustable irradiation angle is installed on the side of the box body. It also includes a storage cavity arranged on the side of the box body for placing record sheets. When the device is in use, two magnet blocks with opposite magnetic poles are used to adsorb and fix the protective cover on the box body 1. However, when the inspector's movement amplitude is too large, the protective cover may be in a state where it is lower on one side of the box body, which may cause the tools inside the box body to move towards the protective cover side. Under the gravity of multiple tools, the adsorption points of the two magnetic blocks may become loose or even move away from each other, resulting in the opening of the protective cover and the loss of tools, affecting the smooth progress of maintenance inspection operations.

[0024] like Figures 1 to 4 As shown in the figure, an auxiliary device for inspection and maintenance of a substation includes a box body 1, a protective cover 2 and a storage cavity 3. Two "U"-shaped mounting brackets 4 are arranged on the outer side of the box body 1. A support plate 5 is rotatably connected to the mounting bracket 4. A cross plate 11 is rotatably connected to the two support plates 5. A fixing block 6 corresponding to the mounting bracket 4 is installed on the outer wall surface of the protective cover 2. A hook ring one 7 that can be sleeved on the outer wall surface of the fixing block 6 is connected to the movable end of the support plate 5. A fastening part 8 for limiting the hook ring one 7 is arranged on the fixing block 6. A disassembly and assembly part 9 for fixing the mounting bracket 4 is arranged on the box body 1. A hoisting limiting part 10 for limiting the cross plate 11 is arranged on the protective cover 2;

[0025] Specifically, by rotating the support plate 5, the placement angle of the hook ring one 7 can be changed, so that the hook ring one 7 can be hooked on the fixing block 6, realizing the preliminary fixation of the hook ring one 7, ensuring the stability of the protective cover 2 closed on the box body 1, and avoiding the protective cover 2 being located below the box body 1 due to the over-large movement amplitude of the patrolman, resulting in the accidental opening of the protective cover 2 and the accidental dropping of tools from the box body 1, ensuring the safety of the tools placed inside the box body 1; through the arranged fastening part 8, when the protective cover 2 is accidentally located below the box body 1, the position of the hook ring one 7 hooked on the fixing block 6 can be limited and fixed, enhancing the firmness of the hook ring one 7 hooked on the fixing block 6, and further ensuring the safety of the tools stored inside the box body 1; through the arranged hoisting limiting part 10, the position of the cross plate 11 can be fixed, so that the rotation angle of the support plate 5 can be limited, ensuring the firmness of the hook ring one 7 hooked on the fixing block 6.

[0026] As Figure 3 shown in the figure, the hoisting limiting part 10 includes a positioning block 101. The positioning block 101 is bonded to the outer wall surface of the protective cover 2. A bendable connecting rod 102 is connected to the movable end of the positioning block 101. A hook ring two 103 is installed at the end of the connecting rod 102 away from the positioning block 101. A positioning ring 105 is hooked on the hook ring two 103. A soft rope 104 is connected between the outer wall surface of the positioning ring 105 and the outer wall surface of the cross plate 11;

[0027] Specifically, by hooking the positioning ring 105 on the hook ring two 103, the fixation of one end of the cross plate 11 can be realized, so that the rotation angle of the support plate 5 can be limited. When hooking the positioning ring 105, the connecting rod 102 can be appropriately bent so that the hook ring two 103 can change its orientation, so that the positioning ring 105 can be successfully hooked on the hook ring two 103.

[0028] As Figure 2 and Figure 4As shown, the fastening portion 8 includes a cavity 808, the side wall of the fixing block 6 is provided with a cavity 808, a fastening rod 807 is inserted into the cavity 808, a sleeve ring 802 is sleeved on the outside of the fastening rod 807, a telescopic rod 803 is fixedly connected to the outer wall of the sleeve ring 802, a through hole 801 for the telescopic rod 803 to pass through is provided on the hook ring 7, an interception block 806 is bonded to the hand-held end of the fastening rod 807, the outer diameter of the interception block 806 is greater than the inner diameter of the cavity 808, and the interception block 806 is made of soft rubber;

[0029] Specifically, by sleeve-connecting the sleeve ring 802 onto the fastening rod 807 and then inserting the fastening rod 807 into the cavity 808, the installation position of the telescopic rod 803 can be fixed. The intercepting block 806 made of soft rubber material can be squeezed and deformed when one end thereof contacts the inner wall of the cavity 808, thereby enhancing the stability of the fastening rod 807 inserted into the cavity 808. When the protective cover 2 is accidentally placed on the lower side of the box body 1, the telescopic rod 803 can be stretched and changed under the action of gravity and gravitation, so that the movable end of the telescopic rod 803 can pass through the through hole 801, thereby improving the firmness of the hook ring 7 hooked on the fixing block 6.

[0030] like Figure 4 As shown, an outer wall surface of the fastening rod 807 close to the fixing block 6 is provided with an external thread 804, and an internal thread 805 is provided inside the cavity 808, and the external thread 804 and the internal thread 805 are threadedly connected;

[0031] Specifically, the external thread 804 and the internal thread 805 can enhance the firmness and stability of the fastening rod 807 installed in the cavity 808 .

[0032] like Figure 4 As shown, the disassembly and assembly part 9 includes a horizontal column 901, and the horizontal column 901 is fixedly installed on the outer wall surface of the box body 1. The left and right side walls of the horizontal column 901 are provided with plug-in cavities 902, and the plug-in cavity 902 is slidably connected with a plug-in block 903 connected to the bottom of the mounting frame 4 at the top;

[0033] Specifically, by slidingly connecting the plug-in block 903 to the inside of the plug-in cavity 902, the mounting frame 4 can be quickly assembled, and the structure is simple and easy to operate.

[0034] like Figure 4 As shown, a magnet block 904 with opposite magnetic properties is connected between the bottom surface of the plug-in block 903 and the inner wall surface of the plug-in cavity 902. The magnet block 904 disposed on the plug-in cavity 902 is located directly below the support plate 5, and the two magnet blocks 904 have the same size.

[0035] Specifically, by providing two magnet blocks 904 with opposite magnetic properties, the magnetic characteristics of the two magnet blocks 904 can be utilized to enhance the stability of the sliding connection of the plug-in block 903 inside the plug-in cavity 902, thereby ensuring the stability of the mounting bracket 4 when in use.

[0036] When in use, the patrolman can close the protective cover 2 on the box body 1 without using tools, and then the patrolman can hold the right end of the horizontal plate 11 to drive the horizontal plate 11 to move, thereby driving the two support plates 5 to rotate at the same time, and then the two hook rings 7 can be hooked on the outer wall surfaces of the two fixing blocks 6 respectively. After the hooking is completed, the soft rope 104 is pulled to make the positioning ring 105 face the side of the hook ring 2 103, and then the hook ring 2 103 is slightly bent (the hook ring 2 103 can be made of rubber material in actual use) so that the positioning ring 105 can be smoothly hooked on the hook ring 2 103, and then the sleeve ring 802 is prevented from being inside the cavity 808, and then the fastening rod 807 is inserted into the cavity 808. At this time, the sleeve ring 802 The sleeve is connected to the outer wall of the fastening rod 807, and the movable end of the sleeve ring 802 faces the through hole 801. The fastening rod 807 is then rotated so that one end of the fastening rod 807 can be threadedly connected to the inside of the cavity 808 to ensure the stability of the fastening rod 807 when in use. When the fastening rod 807 is completely installed in the cavity 808, the interception block 806 made of soft rubber material can be firmly clamped at the front end of the cavity 808 under the extrusion effect. When the patrolman's movement is too large and the protective cover 2 accidentally falls down to the lower side of the box body 1, the telescopic rod 803 can be stretched due to its own gravity and gravitational force, so that the movable end of the telescopic rod 803 can pass through the through hole 801, thereby improving the firmness of the hook ring 7 hooked on the fixing block 6.

[0037] In summary: the placement angle of the hook ring 7 can be changed by rotating the support plate 5, so that the hook ring 7 can be hooked on the fixing block 6 to achieve preliminary fixation of the hook ring 7, ensuring the stability of the protective cover 2 closed on the box body 1, and preventing the patrolman from moving too much and the protective cover 2 being located on the lower side of the box body 1, resulting in the protective cover 2 being accidentally opened, causing the tool to accidentally fall from the box body 1, thereby ensuring the safety of the tool placed inside the box body 1; the set fastening part 8 can limit and fix the position of the hook ring 7 hooked on the fixing block 6 when the protective cover 2 is accidentally located on the lower side of the box body 1, thereby enhancing the stability of the hook ring 7 hooked on the fixing block 6, and further ensuring the safety of the tool stored inside the box body 1; the set lifting limit part 10 can fix the position of the cross plate 11, so that the rotation angle of the support plate 5 can be limited to ensure the stability of the hook ring 7 hooked on the fixing block 6.
