DETAILED DESCRIPTION

[0019] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0020] In the present disclosure, unless otherwise stated, the directional words "upper" and "lower" used generally refer to the "upper" and "lower" relative to each other in the direction of gravity when the corresponding components are in use. In addition, the use of words such as "first" and "second" is intended to distinguish different components and does not have order and importance. In addition, when referring to the drawings in the following description, the same symbols in different drawings represent the same elements. It should be understood by those skilled in the art that the above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.

[0021] According to the specific implementation of the present disclosure, Figures 1 to 3 As shown, a fixed tooling for a power distribution cabinet is provided, wherein the power distribution cabinet comprises a cabinet body 10, an isolation valve 20, and a pull rod 30, wherein the pull rod 30 is hinged between the isolation valve 20 and the cabinet body 10, wherein when the isolation valve 20 is in an open position, the pull rod 30 is in a first position, and when the isolation valve 20 is in a closed position, the pull rod 30 is in a second position, and an idle seat 40 is provided on the cabinet body 10, wherein the fixed tooling is configured to be connected between the idle seat 40 and the pull rod 30, and to selectively maintain the isolation valve 20 in the first position.

[0022] Through the above technical solution, when performing maintenance, the operator presses the rod 30 from the second position to the first position to drive the isolation valve 20 to move from the closed position to the open position, and connects the fixing tool between the idle seat 40 and the rod 30. Since the idle seat 40 is set on the cabinet 10, the fixing tool can be fixed relative to the cabinet 10. In this way, by connecting the rod 30 to the fixing tool, the rod 30 can be fixed relative to the cabinet 10. Therefore, when the rod 30 is in the first position, the fixing tool is connected to the idle seat 40 and the rod 30 to fix the position of the rod 30, so that the rod 30 can be kept in the first position, thereby driving the isolation valve 20 to be kept in the open position, so that the isolation valve 20 can be fixed during the maintenance process to avoid the isolation valve 20 closing to affect the maintenance, or manually pressing the rod 30 to affect the maintenance efficiency.

[0023] Among them, the isolation valve 20 is provided with a pull rod 30 on both sides. During maintenance, the pull rods 30 on both sides of the isolation valve 20 can be fixed with a fixed tool. The idle seat 40 can be the side wall of the cabinet 10, so as to use the structure of the cabinet 10 itself for fixing, and reduce the number of tooling parts. The present disclosure does not limit this. In addition, a connecting rod is provided between the pull rod 30 and the isolation valve 20. By pressing the pull rod 30 downward, one end of the pull rod 30 rotates around the axis, and the other end moves downward, and drives the connecting rod hinged with the pull rod 30 to move downward, so as to drive the isolation valve 20 to move downward, so that the isolation valve moves from the closed position to the open position.

[0024] According to the embodiments provided by the present disclosure, Figure 1 As shown, the fixing tool includes a main plate 1, a first connecting member 2 and a second connecting member 3, wherein the first connecting member 2 is detachably connected between the main plate 1 and the idle seat 40, and the second connecting member 3 is detachably connected between the main plate 1 and the pull rod 30. In this way, when the pull rod 30 is moved to the first position during the overhaul process, the first connecting member 2 and the second connecting member 3 can be connected to the main plate 1 and the idle seat 40 respectively, and the distance between the first connecting member 2 and the second connecting member 3 is limited by the main plate 1, so as to limit the distance between the idle seat 40 and the pull rod 30, so that the position of the pull rod 30 can be maintained in the first position, thereby driving the isolation valve 20 to be in the open position. After the overhaul is completed, the first connecting member 2 and the second connecting member 3 can also be removed from the pull rod 30 and the idle seat 40 respectively, so that the pull rod 30 can be restored to the second position, thereby driving the isolation valve 20 to move to the closed position. Therefore, when the isolation valve 20 is fixed, the operation is simple, and convenient operation can be achieved in the narrow space of the distribution cabinet. At the same time, the first connecting member 2 and the second connecting member 3 are detachably connected to the main body plate 1 so as to realize the rapid disassembly and assembly of the fixing tool.

[0025] According to the embodiments provided by the present disclosure, Figure 1 As shown, the first connecting member 2 is detachably connected to the main body panel 1 and has a first plug rod 21. The idle seat 40 is provided with a first matching hole 101, and the first plug rod 21 is used to be selectively plugged into the first matching hole 101. In this way, since the idle seat 40 is fixed to the cabinet 10, by inserting the first plug rod 21 into the first matching hole 101 on the idle seat 40, the movement of the first plug rod 21 relative to the idle seat 40 is limited by the first matching hole 101, so that the first connecting member 2 can be fixed relative to the cabinet 10, and the position of the main body panel 1 is relatively fixed to the cabinet 10, so that when the pull rod 30 is in the first position, the second connecting member 3 connected between the main body panel 1 and the pull rod 30 can be used to fix the position of the pull rod 30.

[0026] According to the embodiments provided by the present disclosure, Figure 1 As shown, the second connecting member 3 is detachably connected to the main body panel 1 and has a second plug rod 31. The pull rod 30 is provided with a second matching hole 301, and the second plug rod 31 is used to be selectively plugged into the second matching hole 301. In this way, by inserting the second plug rod 31 into the second matching hole 301 on the pull rod 30, the movement of the second plug rod 31 relative to the pull rod 30 is limited by the second matching hole 301, so that the position of the second connecting member 3 can be fixed relative to the pull rod 30. In this way, when the pull rod 30 is moved to the first position, the first plug rod 21 is inserted into the first matching hole 101 to fix the first connecting member 2 and the main body panel 1 relative to the cabinet 10, and the second connecting member 3 connected to the main body panel 1 can be fixed relative to the cabinet 10, and the second plug rod 31 is inserted into the second matching hole 301, so that the pull rod 30 is fixed relative to the cabinet 10 by the second connecting rod, so that the pull rod 30 can be maintained in the first position.

[0027] According to the embodiments provided by the present disclosure, Figure 2 and Figure 3 As shown, the first connector 2 and the second connector 3 both have a first screw, and a threaded hole threadedly connected to the first screw is provided on the main plate 1. In this way, by threading the first screw and the threaded hole on the main plate 1, the first connector 2 and the second connector 3 are detachably connected to the main plate 1, which is easy to operate and improves the assembly efficiency of the fixing tool. In addition, the first screw of the first connector 2 and the first screw of the second connector 3 can also be used as the first plug rod 21 and the second plug rod 31, which are respectively inserted into the first matching hole 101 and the second matching hole 301, so as to increase the friction between the first screw and the first matching hole 101 and the second matching hole 301 through the thread on the first screw, so as to avoid the first connector 2 or the second connector 3 from being separated from the first matching hole 101 or the second matching hole 301, thereby improving the reliability of the fixing tool during use.

[0028] According to the embodiments provided by the present disclosure, Figure 2 and Figure 3 As shown, the threaded hole extends along the thickness direction of the main body plate 1. In this way, when the first screw of the first connecting member 2 and the first screw of the second connecting member 3 are installed on the main body plate 1 along the extension direction of the threaded hole, the first screw and the second screw 41 can be arranged perpendicular to the main body plate 1, so that during operation, the first connecting member 2 and the second connecting member 3 can be aligned and connected with the first matching hole 101 and the second matching hole 301 respectively, thereby improving the installation efficiency of the fixing tool.

[0029] According to the embodiments provided by the present disclosure, Figures 1 to 3 As shown, the spacing between the first plug rod 21 and the second plug rod 31 is 5cm-7cm. In this way, when the first plug rod 21 and the second plug rod 31 are respectively inserted into the first matching hole 101 and the second matching hole 301, the distance between the first matching hole 101 and the second matching hole 301 can be controlled, so that the distance between the pull rod 30 and the idle seat 40 when it is in the first position can be fixed to achieve the fixation of the open position of the isolation valve 20. It is avoided that the spacing between the first plug rod 21 and the second plug rod 31 is too small, which affects the movement of the isolation valve 20 from the closed position to the open position, resulting in the occurrence of a situation that affects the maintenance effect. It is also avoided that the spacing between the first plug rod 21 and the second plug rod 31 is too large, which makes it inconvenient to insert the first matching hole 101 and the second matching hole 301 at the same time to fix the pull rod 30.

[0030] According to the embodiments provided by the present disclosure, Figure 2 and Figure 3 As shown, the main body plate 1 has a first side and a second side that are arranged opposite to each other in the thickness direction thereof, and the first side is provided with a holding structure 4. In this way, the staff can insert the first connecting member 2 and the second connecting member 3 into the first matching hole 101 and the second matching hole 301 respectively by operating the holding structure 4, thereby improving the convenience of the fixing tool operation. Here, in some embodiments, the holding structure can be provided between the first connecting member and the second connecting member.

[0031] According to the embodiments provided by the present disclosure, Figure 2 and Figure 3 As shown, the gripping structure 4 is detachably connected to the main body plate 1. In this way, when the fixed tooling is needed, the fixed tooling can be conveniently assembled to adapt to the narrow space of the power distribution cabinet, and the fixed tooling can be easily disassembled and transported to reduce the occupied space.

[0032] According to the embodiments provided by the present disclosure, Figure 3As shown, the holding structure 4 includes a holding rod, which extends along the thickness direction of the main body plate 1. The holding rod is provided with a second screw rod 41, and a nut 42 is threadedly connected to the second screw rod 41, and the nut 42 abuts against the main body plate 1 from the first side. In this way, by threading the nut 42 to the second screw rod 41 and abutting against the main body plate 1, the second screw rod 41 is fastened relative to the main body plate 1, thereby ensuring the structural stability of the holding rod. In this way, the holding structure 4 can be assembled, and the space occupied by the holding structure 4 is reduced, so that the operator can operate in the narrow space of the cabinet 10.

[0033] Below, reference Figures 1 to 3 As shown, the present disclosure will combine the above-mentioned specific implementation methods to give a detailed introduction to the specific use process of the fixing tooling for the power distribution cabinet. When the power distribution cabinet needs to be repaired, the pull rods 30 on both sides of the isolation valve 20 are pressed from the second position to the first position to drive the isolation valve 20 to move from the closed position to the open position. At this time, the personnel operate the holding rod to align the first connecting member 2 and the second connecting member 3 with the first matching hole 101 on the idle seat 40 and the second matching hole 301 on the pull rod 30, and insert the first plug rod 21 of the first connecting member 2 into the first matching hole 101, and the second plug rod 31 of the second connecting member 3 into the second matching hole 301. Since the first connecting member 2 is relatively fixed to the cabinet body 10, the position of the second connecting member 3 can be fixed by the main body plate 1, and the pull rod 30, which is relatively fixed to the position of the second connecting member 3 and is in the first position at this time, can also be fixed relative to the cabinet body 10 to keep the pull rod 30 in the first position, so that the isolation valve 20 can be kept in the open position. After the inspection is completed, the first plug rod 21 and the second plug rod 31 are removed from the idle seat 40 and the pull rod 30 respectively, so that the pull rod 30 can be restored to the second position to drive the isolation valve 20 to restore to the closed position.
