Description

Technical Field

[0001] This utility model relates to the field of pole-mounted switch technology, and in particular to a pole-mounted switch with a quick installation mechanism. Background Technology

[0002] Pole-mounted switches of medium-voltage circuit breakers are key equipment installed on utility poles. They are designed specifically for medium-voltage power distribution systems and have multiple functions such as circuit isolation, protection systems, and switching operations. They ensure the safety and efficiency of power distribution and are an indispensable and important component for improving power grid reliability and perfecting the power distribution network.

[0003] When installing a pole-mounted switch, first, ensure the installation location is level and use reliable steel wire ropes for hoisting to maintain the equipment's balance. Next, check and connect all accessories, such as surge arresters and isolating switches, ensuring they are securely installed and operate smoothly. Then, when connecting the leads, ensure the terminal type matches the wire and that the contact surfaces are tight. Finally, conduct necessary checks and tests to ensure the switchgear operates normally and the casing is reliably grounded.

[0004] However, existing technologies have some problems: due to their large size and weight, pole-mounted switches are relatively complex and difficult to install. During installation, hoisting equipment is needed to lift them to the predetermined installation position at a high altitude. Various threaded connections are required during installation to ensure the stability and reliability of the switch. Therefore, the limitations of working at height and the diversity of connecting components result in a long installation time and require a high degree of patience and meticulousness from the operators. Furthermore, the excessively long installation and disassembly time not only increases the labor intensity of the operators but also increases their occupational risks. Therefore, we propose a pole-mounted switch with a quick-installation mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pole-mounted switch with a quick-installation mechanism. By setting up a simple quick-installation component and configuring the circuit breaker and mounting base as a plug-in connection, the connection time is reduced, thereby improving installation efficiency and reducing installation risks.

[0006] The purpose of this utility model is achieved as follows: A pole-mounted switch with a quick-installation mechanism includes a base and a mounting base. A connecting block is provided on the base, and the base and mounting base are configured to cooperate with each other. A bottom plate is provided on the mounting base, and a side plate is provided on the mounting base. An installation area is formed between the bottom plate and the side plate. A quick-installation assembly is provided between the connecting block and the side plate. A support plate is provided on the mounting base, and a reinforcing rib is provided between the mounting base and the support plate. Both the mounting base and the support plate are provided with collars.

[0007] Optionally, the lower end of the connecting block is provided with a support leg, and the support leg is provided with a claw groove, and the number of the support legs is multiple.

[0008] Optionally, the quick-installation component includes a limiting pin, on which a hook is provided, the hook being correspondingly provided with a claw groove, and the hook being inserted into the claw groove.

[0009] Optionally, the connecting block has a limiting hole, a protruding ring is provided in the limiting hole, a connecting plate is provided on the side plate, a connecting hole is provided on the connecting plate, the limiting hole, the connecting hole and the limiting pin are correspondingly provided, and the limiting pin is inserted into both the limiting hole and the connecting hole.

[0010] Optionally, a spring is sleeved on the outside of the limiting pin, one end of the spring is fixedly connected to the limiting pin, and the other end of the spring contacts the convex ring.

[0011] Optionally, the limiting pin is provided with a connecting shaft, the connecting shaft is threadedly connected with a post head, and a limiting ring is sleeved on the connecting shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By setting limit pins, connecting shafts, column heads, and limit rings, during installation, after fixing the mounting base to the power pole, place the suspended base on the mounting base, align the connecting block with the connecting plate, and then insert the limit pin through the connecting plate and the connecting block to achieve fixation. After the limit pin passes through the connecting hole, since the inner diameter of the limit ring is larger than that of the connecting shaft, the limit ring can catch the convex ring, fixing the limit pin in the limit hole and preventing the limit pin from falling off.

[0014] 2. By setting up support feet, claw grooves, and hooks, after inserting the limit pin, rotating the limit pin will connect the hooks to the claw grooves, making the hooks and claw grooves tightly connected to form a strong mechanical lock. This not only simplifies the installation steps but also effectively enhances the connection strength between the base and the mounting seat, further improving the stability and safety of the pole-mounted switch installation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 The pole-mounted switch shown includes a base 1 and a mounting base 2. A connecting block 11 is provided on the base 1. The base 1 and the mounting base 2 are fitted together. A base plate 21 and a side plate 22 are provided on the mounting base 2. An installation area is formed between the base plate 21 and the side plate 22. A quick-installation component 3 is provided between the connecting block 11 and the side plate 22. A support plate 4 is provided on the mounting base. A reinforcing rib 41 is provided between the mounting base 2 and the support plate 4. A collar 5 is provided on both the mounting base 2 and the support plate 4.

[0025] Furthermore, the cooperation between the base 1 and the mounting base 2, along with the quick-release assembly 3, significantly improves installation efficiency. The mounting area formed by the base plate 21 and the side plate 22 provides stable support for the switchgear, while the quick-release assembly 3 between the connecting block 11 and the side plate 22 enables a quick and easy assembly process. In addition, the reinforcing rib 41 between the mounting base 2 and the support plate 4 enhances the overall structural stability, and the collar 5 further facilitates installation and disassembly. This not only saves installation time and reduces labor risks but also improves the stability and safety of the switchgear.

[0026] Specifically, the lower end of the connecting block 11 is provided with a support leg 12, and the support leg 12 is provided with a claw groove 13. There are multiple support legs 12.

[0027] Specifically, the quick-install component 3 includes a limit pin 31, on which a hook 32 is provided. The hook 32 is correspondingly provided with a claw groove 13, and the hook 32 is inserted into the claw groove 13.

[0028] Furthermore, the support leg 12 at the lower end of the connecting block 11 not only enhances the stability of the base 1, but the claw groove 13 on the support leg 12 also forms a clever fit with the hook 32 in the quick-installation assembly 3. Through the insertion of the hook 32 into the claw groove 13, the base 1 and the mounting base 2 can be quickly and securely connected together without the need for complex threaded connections or other complicated steps. This not only simplifies the installation process and improves work efficiency, but also ensures the accuracy and stability of the installation, reducing the risks of working at height.

[0029] Specifically, a limiting hole 14 is provided on the connecting block 11, and a protruding ring 15 is provided in the limiting hole 14. A connecting plate 23 is provided on the side plate 22, and a connecting hole 24 is provided on the connecting plate 23. The limiting hole 14, the connecting hole 24 and the limiting pin 31 are correspondingly provided, and the limiting pin 31 is inserted into both the limiting hole 14 and the connecting hole 24.

[0030] Furthermore, the limiting hole 14 on the connecting block 11 and its internal protruding ring 15, the connecting plate 23 on the side plate 22 and its connecting hole 24, together with the limiting pin 31, form a stable installation mechanism. The limiting pin 31 not only ensures a firm connection between the base 1 and the mounting base 2 by inserting into the limiting hole 14 and the connecting hole 24, but the design of the protruding ring 15 further enhances the stability and reliability of the connection.

[0031] Specifically, a spring 33 is sleeved on the outer side of the limiting pin 31. One end of the spring 33 is fixedly connected to the limiting pin 31, and the other end of the spring 33 is in contact with the convex ring 15.

[0032] Furthermore, in the quick-release assembly 3 of the pole-mounted switch, the spring 33 sleeved on the outside of the limit pin 31 enables automatic reset during disassembly, improving operational convenience and ensuring that the limit pin 31 can quickly return to the correct position during reinstallation. Simultaneously, the elastic force of the spring 33 ensures continuous and tight contact between the limit pin 31 and the convex ring 15 and connecting plate 23, effectively preventing loosening of the connection due to vibration or external forces. This not only enhances the stability and reliability of the installation structure but also extends the service life of the switchgear.

[0033] Specifically, a connecting shaft 34 is provided on the limiting pin 31, a post head 35 is threadedly connected to the connecting shaft 34, and a limiting ring 36 is sleeved on the connecting shaft 34.

[0034] It should be noted that the main body of the limiting pin 31 is a stepped shaft at one end. The connecting shaft 34 at the end of the limiting pin 31 is correspondingly set with the convex ring 15. The inner diameter of the limiting ring 36 is larger than that of the connecting shaft 34, so that the limiting ring 36 is always not coaxial with the connecting shaft 34. Both the limiting ring 36 and the post head 35 are provided with chamfers.

[0035] Furthermore, during installation, when the connecting shaft 34 enters the connecting hole 24, the chamfer on the limiting ring 36 facilitates its passage through the connecting hole 24. After the limiting ring 36 passes through the connecting hole 24, since the inner diameter of the limiting ring 36 is larger than that of the connecting shaft 34, the limiting ring 36 falls down and jams the limiting pin 31 in the limiting hole 14, preventing it from moving.

[0036] Working principle: During installation, after fixing the mounting base 2 to the power post, place the suspended base 1 on the mounting base 2, align the connecting block 11 with the connecting plate 23, and then fix the limit pin 31 by passing it through the connecting plate 23 and the connecting block 11. After the limit pin 31 passes through the connecting hole 24, since the inner diameter of the limit ring 36 is larger than the connecting shaft 34, the limit ring 36 can lock the protruding ring 15, fixing the limit pin 31 in the limit hole 14 and preventing the limit pin 31 from falling off.

[0037] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
