Description

Technical Field

[0001] This utility model belongs to the field of power connection equipment technology, and specifically relates to an overhead line power supply connection device. Background Technology

[0002] Existing electrical connectors are often installed in conjunction with public power distribution rooms, platform transformers, etc., so that the electrical connectors can be connected to the public power distribution room to achieve temporary power supply and power draw.

[0003] However, most old residential areas were built without external power supply rooms or transformers, making it impossible to provide power or temporary power. Therefore, when construction, maintenance, or engineering activities are underway, it is difficult to meet their temporary power needs. Utility Model Content

[0004] The purpose of this utility model is to provide an overhead power supply connection device, which enables temporary power supply by quickly connecting with overhead cables and electrical devices, thus solving the problem that old public power distribution rooms cannot be connected to external power sources and therefore cannot provide temporary power.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] This utility model discloses an overhead line power supply connection device, including a device body. The device body includes a fixed base, a movable base, and a drive base. The drive base is movably connected to the fixed base. The movable base includes a first clamping part, and the fixed base includes a second clamping part. The drive base is drivenly connected to the movable base so that the first clamping part moves closer to or further away from the second clamping part. A plug-in socket is movably connected to the end of the drive base away from the movable base.

[0007] The present invention has at least the following beneficial effects: the drive seat and the fixed seat are movably connected, that is, the drive seat can move relative to the fixed seat; the drive seat and the movable seat are drively connected, that is, the drive seat can drive the movable seat so that the movable seat can move relative to the fixed seat, thereby bringing the first clamping part and the second clamping part closer to each other, clamping the cable, completing the connection and installation of the overhead line power supply connection device with the overhead cable, and realizing that the power-consuming device can temporarily draw power from the overhead cable through the overhead line power supply connection device; or the first clamping part and the second clamping part are moved away from each other so that the overhead cable can enter and exit between the first clamping part and the second clamping part, providing a channel for installing and removing the overhead cable of the overhead line power supply connection device.

[0008] The plug-in socket and the drive unit are movably connected. When the drive unit moves the movable unit, the relative positions of the plug-in socket and the drive unit do not change, and the connection between the plug-in socket and the electrical device is not affected.

[0009] As a further improvement to the above technical solution, the fixing seat is provided with a fastening cavity, the fixing seat has an opening for communicating with the fastening cavity, the second clamping part is fixed in the fastening cavity, and the first clamping part can slide in the fastening cavity.

[0010] With the above configuration, the fastening cavity provides space for the first clamping part and the second clamping part to clamp the overhead cable, as well as space for the first clamping part to move. Both the first clamping part and the second clamping part are located in the fastening cavity, and the drive seat drives the first clamping part by driving the movable seat.

[0011] As a further improvement to the above technical solution, the second clamping part is a concave structure, and a sliding groove is provided inside the second clamping part. The first clamping part is located in the sliding groove and can slide relative to the second clamping part in the sliding groove.

[0012] With the above configuration, another sliding method is provided for the first clamping part and the second clamping part. The drive seat drives the first clamping part to slide in the sliding groove, so that the connection between the first clamping part and the second clamping part and the overhead cable is tighter.

[0013] As a further improvement to the above technical solution, a guide assembly is provided between the first clamping part and the second clamping part. The guide assembly includes a guide groove and a guide rod. The fixed seat is provided with the guide groove, which is in communication with the fastening cavity. The guide rod is connected to the movable seat and extends along the moving direction of the movable seat and passes through the guide groove.

[0014] With the above configuration, the guide component is used to guide the linear sliding of the first clamping part and the second clamping part, preventing the two from shifting positions and causing the first clamping part and the second clamping part to fail to accurately abut against the opposite sides of the overhead cable, thus failing to securely clamp the overhead cable.

[0015] As a further improvement to the above technical solution, the fixed seat is provided with a through hole, the through hole is coaxially arranged and connected with the guide groove, the guide rod can pass through the through hole and the guide groove in sequence, and be threadedly connected to the movable seat.

[0016] With the above configuration, the guide rod can be connected to the movable seat through the through hole on the outside of the fixed seat, making the assembly of the overhead line power supply connection device easier.

[0017] As a further improvement to the above technical solution, the side of the first clamping part and the second clamping part that is close to each other is a clamping surface, and the clamping surface is provided with anti-slip stripes, which extend along the sliding direction perpendicular to the movable seat.

[0018] With the above configuration, the anti-slip stripes on the clamping surface are used to increase the friction between the first clamping part and the second clamping part and the overhead cable, preventing the overhead cable from slipping out of the opening.

[0019] As a further improvement to the above technical solution, both clamping surfaces are arc surfaces.

[0020] With the above configuration, the arc-shaped clamping surface can better clamp and secure the overhead cable, preventing the overhead cable and the device body from detaching from each other when drawing power. In addition, the contact area between the two is larger, which facilitates a stable electrical connection between them.

[0021] As a further improvement to the above technical solution, the fixed seat includes a gripping part, the driving seat includes a rotating part and a connecting part that are connected to each other, the gripping part and the rotating part are coaxial and rotatably connected, and the connecting part and the movable seat are threadedly connected.

[0022] With the above configuration, when an external force is applied to the rotating part, the rotating part rotates relative to the gripping part, while the relative positions of the drive seat and the fixed seat remain unchanged. Furthermore, the size of the device itself does not change when installing or removing it from overhead cables, saving installation and storage space. The operator only needs to hold the gripping part with one hand and the rotating part with the other, causing them to rotate relative to each other. This allows the connecting part to rotate relative to the movable seat, converting the rotational motion of the connecting part into the linear motion of the movable seat, thus adjusting the relative distance between the first and second clamping parts.

[0023] As a further improvement to the above technical solution, the movable seat includes a conductive shaft connected to the first clamping part. The conductive shaft passes through the fixed seat, and one end of it away from the first clamping part is threadedly connected to the connecting part.

[0024] Through the above-mentioned device, the rotating connecting part drives the conductive shaft to move linearly through thread engagement. Since the conductive shaft is connected to the first clamping part, the first clamping part moves linearly in the sliding groove. The conductive shaft and the first clamping part are electrically connected. The overhead cable transmits electrical energy to the power-consuming device along the first clamping part, the second clamping part, the conductive shaft, the drive seat, and the plug-in seat.

[0025] As a further improvement to the above technical solution, the rotating part includes a receiving cavity, and the plug-in is located within the receiving cavity and rotatably connected to the connecting part. Through this arrangement, the plug-in is located within the receiving cavity, reducing the length and size of the device body, saving installation and storage space. Furthermore, the rotating part provides insulation protection for the plug-in, preventing accidental electric shock by operators. Because the plug-in and connecting part are rotatably connected, when the rotating part rotates relative to the holding part to adjust the relative positions of the first and second clamping parts, the plug-in is unaffected by the rotation of the rotating part, ensuring a secure connection between the universal plug of the electrical device and the plug-in.

[0040] It should be noted that in the attached diagram, the X direction points from the left side to the right side of the overhead line power take-off connection device; the Y direction points from the bottom side to the top side of the overhead line power take-off connection device.

[0041] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0042] Reference Figures 1 to 2 The following are several embodiments of the overhead line power supply connection device of this utility model.

[0043] like Figure 1 and Figure 2 As shown, the overhead power supply connection device of this utility model embodiment includes a device body 100, which includes a fixed base 200, a movable base 300, and a drive base 400. The drive base 400 is movably connected to the fixed base 200. The movable base 300 includes a first clamping part 310, and the fixed base 200 includes a second clamping part 210. The drive base 400 and the movable base 300 are drive-connected so that the first clamping part 310 moves closer to or further away from the second clamping part 210. A plug-in socket 500 is movably connected to the end of the drive base 400 away from the movable base 300.

[0044] It is understood that the drive seat 400 and the fixed seat 200 are movably connected, meaning that the drive seat 400 can move relative to the fixed seat 200; the drive seat 400 and the movable seat 300 are drive-connected, meaning that the drive seat 400 can drive the movable seat 300 so that the movable seat 300 can move relative to the fixed seat 200, thereby bringing the first clamping part 310 and the second clamping part 210 closer together, clamping the cable, and completing the connection and installation of the overhead line power supply connection device with the overhead cable; or moving the first clamping part 310 and the second clamping part 210 further apart so that the overhead cable can enter and exit between the first clamping part 310 and the second clamping part 210, providing a channel for installing and removing the overhead cable from the overhead line power supply connection device.

[0045] It is understandable that the connector 500 is movably connected to the drive seat 400. When the drive seat 400 drives the movable seat 300, the relative positions of the connector 500 and the drive seat 400 may change because the connector 500 is movably connected to the drive seat 400.

[0046] In this embodiment, the movable seat 300 and the fixed seat 200 move relative to each other in the left-right direction. Specifically, when an external force is applied to the drive seat 400, the drive seat 400 drives the movable seat 300 to move to the left, so that the first clamping part 310 moves away from the second clamping part 210. The operator can then clamp the overhead cable between the first clamping part 310 and the second clamping part 210. Then, an external force in the opposite direction is applied to the drive seat 400, so that the drive seat 400 drives the movable seat 300 to move to the right, so that the first clamping part 310 moves closer to the second clamping part 210, clamping and fixing the overhead cable. This achieves the connection between the device body 100 and the overhead cable. The device body 100 has a simple structure and is easy to operate. The operator only needs to adjust the drive seat 400 to make the movable seat 300 and the fixed seat 200 move relative to each other to achieve the mutual connection between the overhead cable and the overhead power supply connection device.

[0047] It is understandable that before connecting the overhead cable to the overhead power supply connection device, the outer insulating shell at the connection point needs to be removed to enable the connection between the overhead cable and the overhead power supply connection device.

[0048] It is understood that the fixing base 200 has a fastening cavity 220 inside, and the fixing base 200 has an opening 230 that leads to the fastening cavity 220. The second clamping part 210 is fixed in the fastening cavity 220, and the first clamping part 310 can slide in the fastening cavity 220. Figure 2 As shown.

[0049] Understandably, the fastening cavity 220 provides clamping space for overhead cables, and also provides space for the first clamping part 310 to move left and right. The fastening cavity 220 is a cuboid cavity. Since the movable seat 300 and the fixed seat 200 move relative to each other in the left and right direction, the first clamping part 310 is located at the left end of the fastening cavity 220, and the second clamping part 210 is located at the right end of the fastening cavity 220. That is, the second clamping part 210 can be fixedly connected to the left inner wall of the fastening cavity 220 by welding, integral molding, adhesive bonding, etc. The first clamping part 310 can move to the right within the fastening cavity 220 to approach the second clamping part 210, and can also move to the left within the fastening cavity 220 to move away from the second clamping part 210.

[0050] It is understood that the opening 230 is located on the upper end face of the fixed base 200 and leads downward to the fastening cavity 220. When the first clamping part 310 is far away from the second clamping part 210 and the left and right distance between them is large enough, the operator can adjust the position of the device body 100 so that the overhead cable can be inserted into the fastening cavity 220 through the opening 230. At this time, the overhead cable is located between the first clamping part 310 and the second clamping part 210.

[0051] Furthermore, the second clamping part 210 has a concave structure, and a sliding groove 240 is provided inside the second clamping part 210. The first clamping part 310 is located within the sliding groove 240 and can slide relative to the second clamping part 210 within the sliding groove 240, such as... Figure 2 As shown.

[0052] In this embodiment, the shape and size of the second clamping part 210 are equal to the shape and size of the fastening cavity 220, and the second clamping part 210 is securely installed in the fastening cavity 220. The second clamping part 210 has a concave structure, and the sliding groove 240 extends in the front-back direction and connects the front and rear end faces of the second clamping part 210. The upper part of the sliding groove 240 is connected to the opening 230. The first clamping part 310 is located in the sliding groove 240 and can slide left and right in the sliding groove 240 so that the right end face of the first clamping part 310 and the right inner wall face of the sliding groove 240 are close to or far away from each other, thereby realizing the connection between the device body 100 and the overhead cable.

[0053] Furthermore, a guide assembly is provided between the fixed seat 200 and the movable seat 300. The guide assembly includes a guide groove 610 and a guide rod 620. The fixed seat 200 has a guide groove 610, which communicates with the fastening cavity 220. The guide rod 620 is connected to the movable seat 300 and extends along the moving direction of the movable seat 300, passing through the guide groove 610. Figure 2 As shown.

[0054] It is understandable that, since the first clamping part 310 slides relative to the second clamping part 210, the guide component is used to guide the linear sliding of the two to prevent the two from shifting positions, which would cause the first clamping part 310 and the second clamping part 210 to fail to accurately abut against the opposite sides of the overhead cable, thus failing to securely clamp the overhead cable.

[0055] In this embodiment, both the guide groove 610 and the guide rod 620 extend in the left-right direction. Since the second clamping part 210 has a concave structure and the first clamping part 310 moves to the right and approaches the second clamping part 210, the guide groove 610 is located at the right end of the second clamping part 210. The left end of the guide groove 610 is connected to the sliding groove 240, and its right end is connected to the fastening cavity 220. The left end of the guide rod 620 is welded and fixed to the right end face of the first clamping part 310. The right end of the guide rod 620 is always embedded in the guide groove 610.

[0056] It is understandable that the length of the guide rod 620 is greater than the sliding length of the first clamping part 310, so as to avoid the situation where one end of the guide rod 620 disengages from the guide groove 610 when the first clamping part 310 moves away from the second clamping part 210, thus preventing the guide assembly from achieving its guiding function.

[0057] Since the first clamping part 310 is located in the sliding groove 240 of the second clamping part 210, it is difficult for the guide rod 620 to be connected to the first clamping part 310 located in the sliding groove 240, and it is difficult for the interconnected first clamping part 310 and guide rod 620 to be installed in the sliding groove 240 and guide groove 610.

[0058] In this regard, the fixed base 200 is provided with a through hole 250, which is coaxially arranged and connected with the guide groove 610. The guide rod 620 can pass through the through hole 250 and the sliding groove 240 in sequence and be threadedly connected to the movable base 300.

[0059] It is understood that the through hole 250 extends in the left and right direction, and its left end communicates with the guide groove 610, while its right end communicates with the right end face of the fixing seat 200. The first clamping part 310 has a threaded hole that matches the guide rod 620 on the side facing the guide groove 610. The guide rod 620 is screw-shaped. During installation, the first clamping part 310 can be placed in the sliding groove 240, so that the threaded hole and the guide groove 610 are aligned in a straight line. A screwdriver is inserted into one side of the guide rod 620, which drives the guide rod 620 to be inserted into the through hole 250, the guide groove 610 and the threaded hole in sequence, and drives the guide rod 620 to rotate so that the threaded end of the guide rod 620 is screwed into the threaded hole, thereby realizing the connection between the guide rod 620 and the first clamping part 310.

[0060] Furthermore, the side of the first clamping part 310 and the second clamping part 210 that is close to each other is a clamping surface. Anti-slip stripes 700 are provided on the clamping surface, extending along a sliding direction perpendicular to the movable seat 300. Figure 1 and Figure 2 As shown.

[0061] Understandably, the clamping surfaces are the first clamping part 310 and the second clamping part 210, which abut against the overhead cable. The anti-slip stripes 700 are used to increase the friction between the clamping surfaces and the overhead cable, prevent the overhead cable from slipping out of the opening 230 of the device body 100, and ensure a stable connection between the device body 100 and the overhead cable.

[0062] It is understood that, since the movable seat 300 slides in the left-right direction, the anti-slip stripes 700 can extend in the front-back direction and also in the up-down direction. In this embodiment, the anti-slip stripes 700 extend in the front-back direction. When the device body 100 clamps the overhead cable, the left-right extending anti-slip stripes 700 do not interfere with the relative movement of the overhead cable and the device body 100 in the left-right direction, making it convenient to adjust the installation position of the device body 100 left and right.

[0063] Understandably, each clamping surface is provided with several anti-slip stripes 700, and these anti-slip stripes 700 are spaced apart along the vertical direction of the clamping surface. Increasing the number of anti-slip stripes 700 increases the friction of the clamping surface.

[0064] In this embodiment, both clamping surfaces are arc surfaces, such as... Figure 1 and Figure 2 As shown. Since the device body 100 is connected by clamping and abutting the overhead cable, the arc-shaped clamping surface makes it easier to fix the overhead cable between the first clamping part 310 and the second clamping part 210. The upper end of the first clamping part 310 and the upper end of the second clamping part 210 are bent close to each other, making it less likely for the overhead cable to fall out of the clamping range of the device body 100.

[0065] In other embodiments, the two clamping surfaces are two parallel and opposite planes. The two parallel and opposite clamping surfaces allow the device body 100 to be connected to the copper busbar of the distribution cabinet, so that the device body 100 can be directly installed on public power distribution rooms, transformers and other structures, thereby improving the applicability of the device body 100.

[0066] In this embodiment, the distance between the two clamping surfaces can clamp cables with a cross-sectional area of ​​50 to 240 square millimeters.

[0067] It is understandable that the movable seat 300 slides left and right via the drive seat 400. Specifically, the drive seat 400 and the fixed seat 200 are movably connected by a rotatable connection. The fixed seat 200 includes a gripping part 260, and the drive seat 400 includes a rotating part 410 and a connecting part 420 connected to each other. The gripping part 260 and the rotating part 410 are coaxial and rotatably connected, and the connecting part 420 is threadedly connected to the movable seat 300. Figure 1 and Figure 2 As shown.

[0068] It is understandable that the gripping part 260 and the rotating part 410 are coaxially arranged, with the rotation shaft extending left and right. When an external force is applied to the rotating part 410, the rotating part 410 rotates relative to the gripping part 260, but the relative positions of the gripping part 260 and the rotating part 410 do not change. Since the drive seat 400 is connected to the movable seat 300, the rotating part 410 and the connecting part 420 are engaged or fixed. The right end of the connecting part 420 is threadedly connected to the left end of the movable seat 300. When an external force drives the rotating part 410 to rotate relative to the gripping part 260, the threaded connection end converts the rotational motion of the connecting part 420 into the horizontal motion of the movable seat 300, thereby realizing the left and right sliding of the first clamping part 310. Figure 1 and Figure 2 As shown.

[0069] Understandably, the grip portion 260 is provided with multiple anti-slip grooves 270 along its outer circumferential side. The anti-slip grooves 270 are used to increase the friction between the operator's hand and the grip portion 260, so as to facilitate convenient and labor-saving installation or removal of the device body 100.

[0070] It is understandable that the cross-section of the first clamping part 310 is square. Since the first clamping part 310 at the right end of the movable seat 300 moves in the fastening cavity 220 or the sliding groove 240, the lower end face of the first clamping part 310 contacts the lower inner wall surface of the fixed seat 200 or the lower inner wall surface of the second clamping part 210. When an external force is applied to the drive seat 400, the threaded end of the drive seat 400 forces the movable seat 300 to move linearly to the left or right relative to the fixed seat 200, without causing the movable seat 300 to rotate relative to the fixed seat 200.

[0071] It is understood that the movable seat 300 includes a conductive shaft 320, which is connected to the first clamping part 310. The conductive shaft 320 passes through the fixed seat 200, and its end away from the first clamping part 310 is threadedly connected to the connecting part 420.

[0072] Understandably, the fixing base 200 is also provided with a connecting cavity 280, which is connected to the fastening cavity 220. The conductive shaft 320 passes through the connecting cavity 280 and can slide left and right along the connecting cavity 280. The left and right ends of the conductive shaft 320 are connected to the connecting part 420 and the first clamping part 310, respectively. The electrical energy flowing through is transferred from the first clamping part 310 to the conductive shaft 320, and then from the conductive shaft 320 to the connecting part 420, and then from the connecting part 420 to the plug socket 500, so that the electrical device can draw power from the overhead cable.

[0073] It is understandable that the left end of the conductive shaft 320 and the right end of the connecting part 420 are mating threaded ends and threaded holes, so that the left end of the conductive shaft 320 is threaded into the connecting part 420, making the connection between the two stable, and driving the conductive shaft 320 to make linear movement in the left and right directions through the thread engagement.

[0074] Furthermore, the rotating part 410 includes a receiving cavity 411, the plug seat 500 is located in the receiving cavity 411 and is rotatably connected to the connecting part 420.

[0075] It is understandable that the plug socket 500 and the rotating part 410 are coaxially arranged. The plug socket 500 can rotate relative to the rotating part 410. When the universal plug of the electrical device is inserted into the plug socket 500 and an external force is applied to the rotating part 410, the rotating part 410 does not affect the universal plug. This prevents the rotating part 410 from causing the universal plug and the connecting wire of the electrical device to twist. As a result, when the external force is removed, the twisted connecting wire will cause the rotating part 410 to rotate in the opposite direction, which will cause the first clamping part 310 and the second clamping part 210 to move away from each other and become unable to clamp and lock the overhead cable.

[0076] Furthermore, the plug socket 500 and the fixed base 200 are threaded together. When the universal plug of the electrical device is inserted into the plug socket 500, the operator can rotate the universal plug to make the universal plug drive the plug socket 500 to rotate relative to the fixed base 200 until the plug socket 500 is locked relative to the fixed base 200, ensuring that the universal plug and the plug socket 500 are connected and fixed.

[0077] It is understandable that, except for the second clamping part 210 and the connecting part 420, the fixed base 200 and the drive base 400 are both insulating components, providing insulation protection for the conductive shaft 320, the plug-in base 500 and other structures inside.

[0078] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
