[0002] Gas-insulated switchgear is a new generation of switchgear. The main switch can be either a permanent magnet vacuum circuit breaker or a spring-mechanism vacuum circuit breaker. The entire cabinet combines air insulation with a sulfur hexafluoride gas compartment, making it both compact and expandable, suitable for power distribution automation. Gas-insulated switchgear features a compact structure, flexible operation, and reliable interlocking, providing satisfactory technical solutions for various applications (especially harsh environments) and different user requirements. In existing technology CN206471728U, an installation device for gas-insulated switchgear is disclosed, which clamps and fixes the switchgear, facilitating cabinet assembly and welding, improving work efficiency, and consequently, work quality. However, the rotation of the fixing plate in this installation device is limited by locating pins that pass sequentially through a limiting plate and a rotatable fixing plate on a bracket, preventing deflection between the fixing plate and the bracket and ensuring accurate cabinet tilt angle. However, this positioning method has the following technical problems: firstly, the locating pins need to be disassembled and reassembled each time the installation device is used, which is cumbersome; secondly, the locating pins may fall off and be lost during the movement of the installation device, affecting its use. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a fixing device for installing gas-filled cabinets, thereby solving the above-mentioned technical problems.

[0004] In view of this, the present invention provides a fixing device for installing a gas-insulated cabinet, comprising two clamping mechanisms symmetrically arranged and a control mechanism. Each clamping mechanism includes a bracket and a fixing plate. The fixing plate is rotatably mounted on the bracket for engaging and fixing with the gas-insulated cabinet. The control mechanism is mounted on one of the brackets and drives a corresponding fixing component mounted on that bracket to rotate. The clamping mechanism also includes a positioning component, which includes:

[0005] The outer casing is mounted on a bracket;

[0006] A positioning rod, which is axially movable and mounted on the housing, is used to limit the rotation of the fixed plate;

[0008] The reset component is installed inside the housing and is used to reset the positioning rod.

[0009] Furthermore, the driving component includes:

[0010] The abutting part is rotatably disposed inside the outer casing. The abutting part has a cylindrical structure and is provided with a spiral abutting end face.

[0011] The control unit is mounted on the abutment part and exposed outside the housing;

[0012] The positioning rod is also equipped with a contact protrusion, which contacts the abutment end face.

[0013] Furthermore, the drive unit also includes a rotating block, which is detachably mounted on the control unit;

[0014] The outer shell is also provided with a first limiting block and a second limiting block, which are used to abut against the rotating block to limit the rotation range of the rotating block.

[0024] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0026] Example 1:

[0027] This embodiment provides a fixing device for installing a gas-insulated cabinet, including two symmetrically arranged clamping mechanisms and a control mechanism. Each clamping mechanism includes a bracket and a fixing plate. The fixing plate is rotatably mounted on the bracket for engaging and fixing with the gas-insulated cabinet. The control mechanism is mounted on one of the brackets and drives a corresponding fixing component mounted on that bracket to rotate. The clamping mechanism also includes a positioning component, which includes:

[0028] Housing 1, housing 1 is mounted on the bracket;

[0029] Positioning rod 2 is axially movable and mounted on housing 1 to limit the rotation of the fixing plate;

[0030] The driving component 3 is rotatably mounted on the housing 1 along the circumference of the positioning rod 2 and abuts against the end of the positioning rod 2 to push the positioning rod 2 to move.

[0031] Reset component 4 is installed inside the housing 1 and is used for moving and resetting the positioning rod 2.

[0032] In this technical solution, the fixing device for installing the gas-insulated switchgear involves placing the switchgear between two clamping mechanisms. The fixing plates of the clamping mechanisms engage with the switchgear to secure it. A control mechanism allows for rotation and adjustment of the switchgear's position as needed. A positioning component then positions and fixes the fixing plates on the bracket, facilitating the installation and welding of the gas-insulated switchgear.

[0033] The positioning assembly consists of a housing 1, a positioning rod 2, a driving component 3, and a resetting component 4. The housing 1 consists of a fixed base 11 and an end cap 12. A storage slot is provided in the fixed base 11. The resetting component 4 can be a spring and is set in the storage slot. A fixing block 21 is provided on one end of the positioning rod 2, and the other end passes through the spring and the fixed base 11, so that the fixing block 21 and the spring abut against each other. The driving component 3 is also installed in the storage slot and abuts against the fixing block 21 of the positioning rod 2. Then, the end cap 12 is installed on the fixed base 11 to restrict the movement of the driving component. The end cap 12 and the fixed base 11 can be threaded together for easy disassembly and assembly.

[0034] Furthermore, the driving component 3 includes an abutment part 31 and a control part 33. The abutment part 31 is rotatably disposed inside the housing 1. The abutment part 31 has a cylindrical structure and is provided with a spiral abutment end face 32. The control part 33 is mounted on the abutment part 31 and is exposed outside the housing 1. The positioning rod 2 is also provided with a contact protrusion 22, which contacts the abutment end face 32.

[0035] With this structural design, when the operator rotates the control part 33 circumferentially, the contact protrusion 22 will move relative to the spiral abutment end face 32, thereby pushing the positioning rod 2 away from the abutment part 31, and causing the positioning rod 2 to extend out of the outer shell 1. A positioning hole is provided on the fixed plate, which is pre-processed based on actual production experience. By having the positioning rod 2 extend out of the outer shell 1 and pass through the positioning hole, the positioning constraint of the fixed plate can be achieved.

[0036] In summary, the operator uses the circumferential rotation control unit 33 to push the positioning rod 2 axially. The positioning rod 2 extends and passes through the fixed plate, positioning the fixed plate and restricting its rotation, thus achieving the rotational positioning of the gas cabinet. Compared with the existing technology that uses disassembly and assembly of positioning pins to position the fixed plate, this technical solution is more convenient and practical to operate.

[0037] Example 2:

[0038] This embodiment provides a fixing device for installing gas-filled cabinets, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] Furthermore, the drive unit 3 also includes a rotating block 34, which is detachably mounted on the control unit 33;

[0040] The outer casing 1 is also provided with a first limiting block 14 and a second limiting block 15, which are used to abut against the rotating block 34 to limit the rotation range of the rotating block 34.

[0041] In this technical solution, the rotating block 34 can be sleeved on the control part 33 and then fastened with screws or nuts, so that the rotating block 34 can be fixedly connected to the control part 33. The operator can rotate the control part 33 by turning the rotating block 34, thereby pushing the positioning rod 2 to move and achieve the positioning of the fixed plate. By setting the first limiting block 14 and the second limiting block 15 on the end cover 12, the rotation range of the rotating block 34 can be limited, so that the control part 33 will not rotate excessively, effectively avoiding the extension and retraction of the positioning rod 2 being affected.

[0042] Alternatively, the first limiting block 14 and the second limiting block 15 can be set as magnetic blocks, and the rotating block 34 can be made of metal. The first limiting block 14 or the second limiting block 15 can be used to attract and fix the rotating block 34, thereby achieving the effect of fixing the rotating block 34.

[0043] Example 3:

[0044] This embodiment provides a fixing device for installing gas-filled cabinets, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] Furthermore, the positioning rod 2 is also provided with a positioning protrusion 23, and the positioning protrusion 23 is located inside the abutment portion 31.

[0046] In this technical solution, a positioning protrusion 23 is provided on the fixing block 21 of the positioning rod 2. The positioning protrusion 23 and the cylindrical abutment part 31 are inserted and cooperated to achieve a positioning effect on the abutment between the positioning rod 2 and the abutment part 31, thereby enhancing the connection stability between the positioning rod 2 and the abutment part 31.

[0047] Example 4:

[0048] This embodiment provides a fixing device for installing gas-filled cabinets, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0049] Furthermore, the outer casing 1 has an axially oriented guide groove 13, and the positioning rod 2 has a connecting protrusion 24 that is adapted to and connected to the guide groove 13. Furthermore, there are multiple guide grooves 13 and connecting protrusions 24, and they are connected one-to-one.

[0050] In this technical solution, by providing a connecting protrusion 24 and a guide groove 13 that are adapted to each other, the movement of the positioning rod 2 can be positioned and guided, preventing the positioning rod 2 from circumferentially deflecting and effectively enhancing the movement stability of the positioning rod 2. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many other forms without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
