[0001] This utility model specifically relates to a tenon-and-mortise type substation support foundation, belonging to the field of substation support technology. Background Technology

[0002] Substation support foundations are primarily used to support and secure various equipment and components within a substation, ensuring their stable placement in their designated positions and proper connection to other equipment and cables. Substation support foundations are an indispensable part of substation construction, playing a crucial role in ensuring stable operation, improving safety and reliability, and facilitating maintenance and management. Existing substation support foundations are typically used at fixed heights. When installing electrical equipment at different heights, it's necessary to replace the support foundations with those of different heights to ensure proper cable connections, which is inconvenient. Furthermore, the electrical equipment is usually fixed to the support using methods such as welding and bolting, making disassembly difficult during maintenance and impacting maintenance efficiency. These practices present certain drawbacks in their use.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a tenon-and-mortise type substation support foundation to solve the above problems. It has the advantage of installing substation infrastructure at different heights, improving the overall flexibility of the support structure, and can be disassembled and assembled together with the power distribution support platform, making it more convenient to use and improving the ease of infrastructure maintenance.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a mortise and tenon type substation support foundation, including a counterweight mounting base, a connecting support fixedly mounted on the top of the counterweight mounting base, and the connecting support being fixedly connected to the counterweight mounting base through a lifting mortise and tenon connecting assembly; a connecting protrusion fixedly mounted on the top of the connecting support, a power distribution support platform mounted on the connecting protrusion platform, and the power distribution support platform being fixedly inserted into the convex embedded slot opened on the top of the connecting protrusion platform through a movable unlocking elastic snap-fit ​​assembly.

[0006] Furthermore, in order to enable the U-shaped locking block to connect with the connecting support, the lifting tenon and mortise connection assembly includes the U-shaped locking block and the vertical connecting block. The connecting support has a first insertion hole on its side wall, and one end of the U-shaped locking block is inserted into the first insertion hole.

[0007] Furthermore, in order to fix the connecting support and the vertical connecting block together by means of the U-shaped locking block, the second insertion hole is linearly and evenly provided on the side wall of the vertical connecting block, and the other end of the U-shaped locking block is inserted into the second insertion hole.

[0008] Furthermore, in order to fix the U-shaped block in the second insertion hole by means of the limiting pin, the U-shaped block and the vertical connecting block are provided with vertically corresponding limiting pin holes, the limiting pin is inserted into the limiting pin hole, and the pull-out connector is fixedly installed on the top of the limiting pin.

[0009] Furthermore, in order to enable the limiting slide rod to be fixedly connected to the power distribution support platform via the fixed mounting base, the movable unlocking elastic snap-fit ​​assembly includes the fixed mounting base, which is fixed to the bottom of the power distribution support platform, and the limiting slide rod is fixedly installed on the inner wall of the fixed mounting base.

[0010] Furthermore, in order to enable the power distribution support platform to be fixedly connected to the connecting protrusion platform through the first limiting connector and the second limiting connector, the L-shaped connecting plate is slidably sleeved at both ends of the limiting slide rod, and the first limiting connector and the second limiting connector are respectively fixedly installed on the L-shaped connecting plate at both ends, and the first limiting connector and the second limiting connector are respectively snapped into the two ends of the convex embedded slot.

[0011] Furthermore, in order to enable the L-shaped connecting plate to drive the first limiting connector and the second limiting connector to be fixed in the convex embedded slot through the clamping spring, the L-shaped connecting plate is elastically connected to the inner wall of the fixed mounting base through the clamping spring.

[0012] Furthermore, in order to control the drive plate so that the L-shaped connecting plate can slide on the limiting slide rod, thereby allowing the first limiting connector and the second limiting connector to disengage from both ends of the convex mounting slot, the drive plate is fixedly installed on the side wall of the L-shaped connecting plate, and the drive plate is slidably engaged in the clearance groove opened on the top of the connecting protrusion.

[0013] The technical effects and advantages of this utility model are as follows: The height of the connecting support and the power distribution support platform can be adjusted by the lifting tenon and mortise connection component, which allows the substation infrastructure to be installed at different heights, effectively improving the overall flexibility of the support and meeting different usage needs.

A connecting support 2 is fixedly mounted on the top of the counterweight mounting base 1, and the connecting support 2 is fixedly connected to the counterweight mounting base 1 via a lifting mortise and tenon connecting assembly 3. A connecting protrusion 4 is fixedly mounted on the top of the connecting support 2, and a power distribution support platform 5 is mounted on the connecting protrusion 4. During use, the height of the connecting support 2 can be slightly adjusted by controlling the lifting mortise and tenon connecting assembly 3, thereby... The height of the power distribution support platform 5 is easily adjustable, making it more flexible to meet different usage needs. The power distribution support platform 5 is fixedly inserted into the convex mounting slot 7 on the top of the connecting protrusion platform 4 by a movable and unlockable elastic snap-fit ​​component 6. When in use, the substation infrastructure is built on the power distribution support platform 5. When maintaining the infrastructure, the movable and unlockable elastic snap-fit ​​component 6 allows for quick disassembly and assembly of the infrastructure without disassembling the entire device from its installation position. This makes it more flexible and convenient to use and improves the efficiency of substation infrastructure maintenance.

[0023] The lifting tenon-and-mortise connection assembly 3 includes a U-shaped locking block 301 and a vertical connecting block 302. A first insertion hole 303 is provided on the side wall of the connecting support 2. One end of the U-shaped locking block 301 is inserted into the first insertion hole 303. A second insertion hole 304 is linearly and evenly provided on the side wall of the vertical connecting block 302. The other end of the U-shaped locking block 301 is inserted into the second insertion hole 304. Vertically corresponding limiting pin holes are provided on the U-shaped locking block 301 and the vertical connecting block 302. A limiting pin 305 is inserted into the limiting pin hole, and a pull-out connector 3 is fixedly installed on the top of the limiting pin 305. 06. In use, first insert one end of the U-shaped locking block 301 into the first insertion hole 303 to connect the U-shaped locking block 301 to the connecting support 2. Adjust the height of the connecting support 2 according to the installation requirements of the substation infrastructure, and insert the other end of the U-shaped locking block 301 into the second insertion hole 304 to achieve a fixed connection between the connecting support 2 and the vertical connecting block 302. This is more flexible and convenient to use. At the same time, insert the limiting pin 305 into the limiting pin hole to facilitate the positioning of the U-shaped locking block 301 and improve the stability of the installation of the connecting support 2.

[0024] The movable, unlockable, elastic locking assembly 6 includes a fixed mounting base 601, which is fixed to the bottom of the power distribution support platform 5. A limiting slide rod 602 is fixedly installed on the inner wall of the fixed mounting base 601. L-shaped connecting plates 603 are slidably sleeved at both ends of the limiting slide rod 602. A first limiting locking connector 604 and a second limiting locking connector 605 are fixedly installed on the L-shaped connecting plates 603 at both ends, respectively. The first limiting locking connector 604 and the second limiting locking connector 605 are respectively locked into the two ends of the convex embedded locking groove 7. The L-shaped connecting plate 603 is elastically connected to the inner wall of the fixed mounting base 601 through a retaining spring 606. A driving lever 607 is fixedly installed on the side wall of the L-shaped connecting plate 603. The driving lever 607 is slidably locked into the clearance groove 8 opened on the top of the connecting protrusion 4. In use, the power distribution support platform 5 is placed on the connecting protrusion 4, and the first limiting locking connector 604 and the second limiting locking connector 605 are locked into the groove 8 opened on the top of the connecting protrusion 4. The locking connector 605 abuts against the top two ends of the convex embedded groove 7, causing the L-shaped connecting plate 603 to slide on the limiting slide rod 602 and stretching the clamping spring 606. When the first limiting locking connector 604 and the second limiting locking connector 605 are fully placed in the convex embedded groove 7, under the action of the clamping spring 606, the first limiting locking connector 604 and the second limiting locking connector 605 are fixedly locked at the bottom two ends of the convex embedded groove 7, realizing the fixed connection between the power distribution support platform 5 and the connecting support 2. It also controls the drive plate 607 to slide in the clearance groove 8, so that the L-shaped connecting plate 603 can drive the first limiting locking connector 604 and the second limiting locking connector 605 to disengage from the two ends of the convex embedded groove 7, so that the power distribution support platform 5 can be removed from the connecting support 2. This effectively improves the convenience of disassembly and assembly of the power distribution support platform 5, making the disassembly and maintenance of substation infrastructure more convenient.
