Description

Technical Field

[0001] The utility model relates to the technical field of shore power plugs, and particularly relates to a forced separation structure for a shore power plug. Background Art

[0002] The ship-shore connection system refers to the cables and equipment used to connect the shore and the ship's power receiving device, and is the core module for the stable and safe operation of the entire shore power system. The ship-shore connection equipment can be installed on ships, docks or barges, and mainly includes quick connectors (plug and socket), shore power connection boxes, cable suspension and lifting equipment, auxiliary plugging and unplugging equipment, and various power transformation and distribution facility components, etc. The high-voltage socket, shore power socket box, and shore power box need to be plugged in by an external plug to the shore power socket box to play a role in connecting power supply.

[0003] There is a prior art with the publication number CN210468194U and the name of "a shore power socket", which includes a socket body, a cover body and spherical head pins that cooperate with the socket body. The socket body is provided with a plug area and a functional area. The spherical head pins pass through the guiding channel between the plug area and the functional area and can move relatively. An elastic piece that can undergo elastic deformation is arranged in the functional area. When the pulling force on the plug exceeds the critical value, the spherical head pins move towards the functional area and squeeze the elastic piece, so that the plug is separated from the socket body. The shore power socket with a high waterproof level of the present utility model can set the pulling force value for forced separation by installing spherical head pins. When the plug is subjected to a pulling force far exceeding the normal plugging and unplugging force, the spherical head pins will forcibly squeeze the elastic piece in the shell, causing them to be misaligned, and finally forcibly separating the plug.

[0004] However, the above-mentioned shore power socket does not have a forced separation function during use. In docks and other scenarios, there are many unexpected factors. For example, in strong winds, heavy rains and bad weather, it may not be possible for workers to unplug the plug from the shore power box in time. Often, the cable is directly pulled at a place far from the shore power box. In this case, if there is no forced separation function, it will directly damage power supply equipment such as the shore power box and cause dangerous accidents. Summary of the Utility Model

[0005] The utility model solves the problems in the related art and provides a forced separation structure for a shore power plug.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions: A forced separation structure for a shore power plug, comprising a support member, a fitting member, a plug and a socket. The support member includes a bracket. The bottom end of the bracket is vertically threaded and assembled with a fixing screw, and the top end of the bracket is rotatably connected to a rotating frame. The fitting member includes a sliding plate. The sliding plate is fixed at the end of the rotating frame, and a cylindrical plate is vertically fixed at one end of the top surface of the sliding plate close to the rotating frame. The plug is horizontally and limitably inserted into the cylindrical plate. A sliding seat is vertically fixed on the bottom surface of the socket, and the sliding seat is horizontally slidably assembled on the sliding plate. A second spring is horizontally fixed on one side end surface of the sliding seat close to the plug, and a clamping frame is vertically fixed on the side end surface of the sliding seat away from the plug.

[0007] As a preferred solution, a turning motor is horizontally fixed on the upper part of the vertical end surface of the bracket, and a driving gear is horizontally fixed at the output end of the turning motor.

[0008] As a preferred solution, a driven gear is fixed at one end of the rotating frame, and the driven gear meshes with the driving gear.

[0009] As a preferred solution, a guide hole cylinder is vertically slidably penetrated and fixed on the outer circumferential surface of the cylindrical plate, and a locking plug rod is vertically slidably penetrated and assembled on the guide hole cylinder.

[0010] As a preferred solution, a first spring is sleeved on the outer circumferential surface of the locking plug rod, and both ends of the first spring are respectively fixed on the end of the locking plug rod and the outer wall of the guide hole cylinder.

[0011] As a preferred solution, a locking hole is vertically opened on the outer wall of the plug, and the locking hole is limitably inserted and connected with the locking plug rod.

[0012] As a preferred solution, an electric telescopic rod is vertically fixed at one end of the bottom surface of the sliding seat close to the rotating frame, and the top end of the electric telescopic rod vertically penetrates through the sliding plate and is fixed with a clamping block, and the clamping block is vertically slidably clamped in the clamping frame.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: During use, the plug is inserted into the cylindrical plate of the sliding plate, and the plug is fixed in the cylindrical plate. The sliding seat is horizontally slidably assembled on the sliding plate, and then the sliding seat on the socket is slid to drive the socket to be inserted into the plug on the cylindrical plate, thus completing the assembly of the plug and the socket. The electric telescopic rod is started to push the clamping block into the clamping frame of the clamping block, limiting the stability of the plug and the socket being pressed and assembled. At the same time, the spring is deformed on the cylindrical plate under the pressure of the socket. Then, during later separation, the electric telescopic rod is started to push the clamping block out of the clamping frame of the clamping block, and the socket is pushed out of the plug by the deformation force of the spring, thereby completing the forced separation of the socket and the plug. The socket and the plug have the function of forced separation, which is convenient for quick separation and improves safety. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] It should be noted that the terms used here are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Without contrary statements, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present utility model; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0024] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above", etc. can be used here to describe the spatial positional relationships between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0025] In addition, it should be noted that the use of terms such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components. Without otherwise stating, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0026] Such asFigures 1 to 5 As shown in the figure, a forced separation structure for a shore power plug includes a support member 1, a fitting member 2, a plug 3, and a socket 4. The support member 1 includes a bracket 11. A fixing screw 111 is vertically threaded through the bottom end of the bracket 11, and a rotating frame 12 is rotatably connected to the top end of the bracket 11. The fitting member 2 includes a sliding plate 21. The sliding plate 21 is fixed to the end of the rotating frame 12. A cylindrical plate 22 is vertically fixed to the top surface of the sliding plate 21 near one end of the rotating frame 12. The plug 3 is horizontally and limit-inserted into the cylindrical plate 22. A sliding seat 41 is vertically fixed to the bottom surface of the socket 4, and the sliding seat 41 is horizontally slidably assembled on the sliding plate 21. A second spring 43 is horizontally fixed to one side end surface of the sliding seat 41 close to the plug 3, and a clamping frame 42 is vertically fixed to the other side end surface of the sliding seat 41 away from the plug 3. An electric telescopic rod 23 is vertically fixed to one end of the bottom surface of the sliding seat 41 near the rotating frame 12, and the top end of the electric telescopic rod 23 vertically penetrates through the sliding plate 21 and is fixed with a clamping block 24, and the clamping block 24 is vertically slidably clamped in the clamping frame 42. During use, the plug 3 is inserted into the cylindrical plate 22 of the sliding plate 21, the plug 3 is fixed in the cylindrical plate 22, the sliding seat 41 is horizontally slidably assembled on the sliding plate 21, and then the sliding seat 41 on the socket 4 is slid to drive the socket 4 to be inserted onto the plug 3 on the cylindrical plate 22, thus completing the assembly of the plug 3 and the socket 4. The electric telescopic rod 23 is started to push the clamping block 24 to be inserted into the clamping frame 42 of the clamping block 24, limiting the stability of the pressed assembly of the plug 3 and the socket 4. At the same time, the spring 43 is deformed on the cylindrical plate 22 under the pressure of the socket 4. Then, during later separation, the electric telescopic rod 23 is started to push the clamping block 24 to be pulled out of the clamping frame 42 of the clamping block 24, and the socket 4 is pushed out of the plug 3 by the deformation force of the spring 43, thus completing the forced separation of the socket 4 and the plug 3. The socket 4 and the plug 3 have a forced separation function, which is convenient for quick separation and improves safety.

[0027] In one embodiment, as Figure 2 and 5 shown, a reversing motor 14 is horizontally fixed to the upper part of the vertical end surface of the bracket 11, and a driving gear 15 is horizontally fixed to the output end of the reversing motor 14. One end of the rotating frame 12 is fixed with a driven gear 13, and the driven gear 13 meshes with the driving gear 15. During use, the reversing motor 14 is started to drive the driving gear 15 to rotate, and the driven gear 13 on the rotating frame 12 is driven to rotate through meshing, driving the sliding plate 21 to incline downward, facilitating sliding and assisting the forced separation of the socket 4 and the plug 3.

[0028] In one embodiment, as Figure 3 and 4A guide hole cylinder 221 is vertically and slidably penetrated and fixed on the outer circumferential surface of the shown cylinder plate 22, and a locking plug 222 is vertically and slidably penetrated and assembled on the guide hole cylinder 221. A first spring 223 is sleeved on the outer circumferential surface of the locking plug 222, and both ends of the first spring 223 are respectively fixed on the end of the locking plug 222 and the outer wall of the guide hole cylinder 221. A locking hole 31 is vertically opened on the outer wall of the plug 3, and the locking hole 31 is in limit plug connection with the locking plug 222. During use, when the plug 3 is assembled with the cylinder plate 22, the locking plug 222 is pulled to slide vertically upward on the guide hole cylinder 221, pushing the first spring 223 to deform. Then the plug 3 is inserted into the cylinder plate 22. When the locking plug 222 is released, under the action of the deformation force of the first spring 223, the locking plug 222 is pushed to insert into the locking hole 31 of the plug 3, limiting and assembling the plug 3 in the cylinder plate 22, and completing the fixed assembly of the plug 3 and the cylinder plate 22.

[0029] In this embodiment, during use, the plug 3 is inserted into the cylinder plate 22 of the slide plate 21, and the plug 3 is fixed in the cylinder plate 22. The sliding seat 41 is horizontally slidably assembled on the slide plate 21. Then, the sliding seat 41 on the sliding socket 4 is driven to drive the socket 4 to be inserted onto the plug 3 on the cylinder plate 22, thus completing the assembly of the plug 3 and the socket 4. The electric telescopic rod 23 is started to push the clamping block 24 to insert onto the clamping frame 42 of the clamping block 24, limiting the stability of the plug 3 and the socket 4 being pressed and assembled. At the same time, the spring 43 is deformed on the cylinder plate 22 under the pressure of the socket 4. Then, during later separation, the electric telescopic rod 23 is started to push the clamping block 24 to pull out the clamping block 24 from the clamping frame 42. The socket 4 is pushed by the deformation force of the spring 43 to pull out the plug 3, thus completing the forced separation of the socket 4 and the plug 3. The socket 4 and the plug 3 have the function of forced separation.

[0030] The above is the preferred embodiment of the present invention. Those skilled in the art of the present invention can also make changes and modifications to the above embodiment. Therefore, the present invention is not limited to the above specific embodiment. Any obvious improvement, replacement or variation made by those skilled in the art on the basis of the present invention belongs to the protection scope of the present invention.
