Description

Technical Field

[0001] This utility model relates to the field of shore power technology, specifically to a high-voltage shore power socket interlocking device. Background Technology

[0002] Shore power, also known as shore-based variable frequency power, is also called electronic static shore power. A socket is a device through which various wires can be inserted, facilitating connection to other circuits. The connection and disconnection of the circuit is achieved through the connection and disconnection of the wires and copper components. High-voltage shore power sockets, such as the high-voltage shore power socket disclosed in Chinese Patent Publication No. CN202872069U, have a structure including a socket body, a socket cover, and a handle. Because high-voltage shore power sockets are directly connected to high-voltage electricity, a strong electric arc is generated when the high-voltage plug is inserted or removed. If two adjacent high-voltage shore power sockets are opened simultaneously, the arc may cause the adjacent sockets to connect, potentially damaging the equipment or causing a safety accident. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a high-voltage shore power socket interlocking device to prevent two high-voltage shore power sockets from being opened simultaneously.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A high-voltage shore power socket interlocking device includes a mounting plate and at least two socket bodies mounted on the mounting plate. Each socket body is provided with a socket cover and a push handle. It also includes:

[0006] The limiting seat is mounted on the mounting plate and located between the socket bodies;

[0007] The limiting rod passes through the limiting seat and circumferentially engages with the limiting seat;

[0008] A through groove is provided on the limit seat;

[0009] A limiting post is installed on the limiting rod and passes through the through groove;

[0010] The first slot is vertically positioned on one side of the through slot and is connected to the through slot;

[0011] Card slot No. 2 is set parallel to card slot No. 1 and is connected to the through slot;

[0012] When the limiting post engages with the first slot, the limiting rod abuts against the pusher near the first slot and disengages from the pusher near the second slot.

[0013] When the limiting post engages with the second slot, the limiting rod abuts against the pusher near the second slot and disengages from the pusher near the first slot.

[0014] A third slot is provided between the first slot and the second slot. When the limiting post is engaged with the third slot, the limiting rod abuts against the pushers on both sides.

[0015] Both the limiting rod and the limiting post are made of high-pressure resistant, flame-retardant, and insulating material.

[0016] The vertical and horizontal positions of the limiting rod are adjustable.

[0017] It also includes a base disposed between the mounting plate and the limiting seat, the base having a first waist hole for cooperating with the mounting plate, and the limiting seat having a second waist hole for cooperating with the base, the first waist hole and the second waist hole being arranged perpendicularly.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] In the embodiments, such as Figure 1 , Figure 3 , Figure 4 As shown, the high-voltage shore power socket interlocking device includes a mounting plate 1 and at least two socket bodies mounted on the mounting plate 1. Each socket body is provided with a socket cover and a push handle 2. It also includes:

[0030] Limiting seat 3 is installed on mounting plate 1 and located between socket bodies;

[0031] Limiting rod 4 passes through limiting seat 3 and circumferentially engages with limiting seat 3;

[0032] Through groove 5 is provided on limit seat 3;

[0033] The limiting post 6 is set on the limiting rod 4 and passes through the through groove 5;

[0034] Card slot 7 is vertically positioned on one side of through slot 5 and is connected to through slot 5;

[0035] Card slot 8 is arranged parallel to card slot 7 and is connected to through slot 5;

[0036] When the limiting post 6 is engaged with the first slot 7, the limiting rod 4 abuts against the pusher 2 near the first slot 7 and disengages from the pusher 2 near the second slot 8.

[0037] When the limiting post 6 is engaged with the second slot 8, the limiting rod 4 abuts against the pusher 2 near the second slot 8 and disengages from the pusher 2 near the first slot 7.

[0038] The limiting rod 4 can rotate within the limiting seat 3 and move left and right relative to the limiting seat 3. The worker can hold the limiting post 6 and move it within the through groove 5. When the limiting post 6 is engaged with the first slot 7 or the second slot 8, the limiting rod 4 abuts against the pusher 2 of one of the high-voltage shore power sockets and disengages from the pusher 2 of the other high-voltage shore power socket, thereby ensuring that only one high-voltage shore power socket can be opened and preventing the situation where two high-voltage shore power sockets are opened at the same time.

[0039] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a third slot 9 is provided between the first slot 7 and the second slot 8. When the limiting post 6 is engaged with the third slot 9, the limiting rod 4 abuts against the pushers 2 on both sides. When the limiting post 6 is engaged with the third slot 9, the pushers 2 on both sides are limited, and the socket cover cannot be opened, thus serving as a safety measure.

[0040] In this embodiment, both the limiting rod 4 and the limiting post 6 are made of high-voltage resistant flame-retardant insulating material. The high-voltage resistant flame-retardant insulating material is PEEK resin or polysilazane, used to prevent the electric arc from contacting the limiting rod 4 when the high-voltage shore power socket is opened, thus preventing the limiting rod 4 and the limiting post 6 from becoming conductive, thereby ensuring the safety of the staff.

[0041] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the vertical and horizontal positions of the limiting rod 4 are adjustable; it also includes a base 10 disposed between the mounting plate 1 and the limiting seat 3. The base 10 has a first waist hole 11 for engaging with the mounting plate 1, and the limiting seat 3 has a second waist hole 12 for engaging with the base 10. The first waist hole 11 and the second waist hole 12 are arranged perpendicularly. By adjusting the vertical position of the base 10 and the horizontal position of the limiting seat 3, it is ensured that the limiting rod 4 can resist the pusher 2 and disengage from the pusher 2.

[0042] In this embodiment, the dimensions of the limiting post 6 match the dimensions of the first slot 7 and the second slot 8. After the limiting post 6 is engaged with the first slot 7 and the second slot 8 respectively, the limiting post 6 will not move easily, and the engagement is stable.

[0043] In the embodiments, such as Figure 5 As shown, the bottom of the limiting post 6 is provided with a connecting hole 13, and one side of the limiting rod 4 is provided with a countersunk hole 14 for engaging with the connecting hole 13. The limiting post 6 passes through the other side of the limiting rod 4. The limiting post 6 and the limiting rod 4 can be machined separately, and then the limiting post 6 is connected through one side of the limiting rod 4 by a countersunk bolt, resulting in a simple structure.

[0044] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
