Description

Technical Field

[0001] The invention relates to a JP cabinet live working power supply connection device, belonging to the technical field of power system equipment. Background Art

[0002] JP cabinet, also known as JP low-voltage integrated distribution box, is a type of distribution cabinet. JP distribution cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. It is mainly used in low-voltage distribution systems.

[0003] When the power transmission line is out of power, the JP cabinet is usually powered by the power supply vehicle to ensure the normal power supply of residents, and the JP cabinet is connected to the power supply vehicle by a connector to achieve power supply. Since the installation location of the JP cabinet is usually at a certain height and is erected in the air, when the power supply vehicle is used for power supply, personnel are usually required to climb to a relatively high height and open the door of the JP cabinet for connection. In the process of climbing, there are not only certain safety risks, but also the cabinet door needs to be opened and closed many times, and the work efficiency is relatively low, so it is urgent to improve.

[0004] A multifunctional combined JP cabinet disclosed in a Chinese invention patent with publication number CN116247534A includes a cabinet body, in which: an isolating switch, a molded case circuit breaker, a branch circuit breaker and a grounding switch are fixedly arranged; a wiring hole is provided on the isolating switch, and the wiring hole is used to connect the three-phase line; the isolating switch is electrically connected to the molded case circuit breaker, a busbar is provided between the molded case circuit breaker and the branch circuit breaker, and the molded case circuit breaker and the branch circuit breaker are electrically connected through the busbar; a first three-phase line group and a second three-phase line group are provided on the branch circuit breaker, the first three-phase line group is electrically connected to the grounding switch, and the second three-phase line group is electrically connected to the user end.

[0005] Although the above reference example is provided with a power access port on the cabinet, the power access port is exposed to the outside and has poor protection. In addition, since the power access port is arranged at the bottom of the cabinet, when connecting the connector of the power supply vehicle to the power access port, the operator will consume a lot of physical strength on the ladder to achieve the installation connection, which increases the safety risk. Therefore, improvement is urgently needed. Summary of the invention

[0019] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0020] 1. The present invention electrically connects one end of the flexible cable to the connector and the other end to the clamping device. The design of the flexible cable can provide a certain range of motion, so that the clamping device can be flexibly installed on the power supply element inside the cabinet and is suitable for JP cabinets of different sizes. At the same time, the clamping device can be detachably installed and can be replaced and repaired at any time, thereby improving the versatility and adaptability of the device.

[0021] 2. In the present invention, when the operators climb to a height, the auxiliary installation mechanism can assist in clamping the power supply head of the power supply vehicle and aligning it with the connector, thereby further improving the installation efficiency. Furthermore, since the JP cabinet is generally arranged at a relatively high position and the connector is arranged at the bottom of the cabinet, the auxiliary installation mechanism can make it easier and safer for the operators to connect the power supply head of the power supply vehicle, thereby effectively reducing the operation risk. When the operators' hand strength is insufficient or the operation is unstable at a height, the auxiliary installation mechanism can provide additional clamping and fixation for the power supply head of the power supply vehicle, thereby ensuring that the power supply head and the connector of the power supply vehicle can be accurately and firmly connected.

[0022] 3. The present invention is facing the JP cabinets that have been put into use. The operators can also install the device in the JP cabinet through the connector. When the power supply vehicle is needed, the JP cabinet that has been put into use can also perform power supply operations without opening the cabinet. That is, the device is not only suitable for newly installed JP cabinets, but also can be used to transform and upgrade existing JP cabinets. It has good compatibility and practicality and is suitable for wide promotion and use in the power system. In some old communities or remote areas of the JP cabinet transformation projects, the device can be used to achieve fast and safe power supply connection, improve the reliability and flexibility of power supply.

[0023] 4. The present invention provides an auxiliary installation mechanism. During the rotation of the sleeve ring, the swing rods of each clamping unit swing at a certain angle. While the three swing rods swing, they drive the positioning blocks to approach each other, so that the positioning blocks clamp and position the power supply head of the power supply vehicle. Since the three positioning blocks are approaching each other at the same time, the power supply head of the power supply vehicle can be very accurately aligned with the connecting head, thereby realizing auxiliary alignment and installation, which is not only efficient but also safe. Moreover, since the positioning blocks and the swing rods are rotatably installed, when the operator places the power supply head of the power supply vehicle between the three positioning blocks and tightens it, the power supply head of the power supply vehicle can also be rotated and adjusted to prevent the cable output by the power supply vehicle from being excessively wound, thereby ensuring the stability of the connection. At the same time, after the three positioning blocks tighten the power supply head of the power supply vehicle, the power supply head can be prevented from falling off the ground, thereby further ensuring the stability of the connection and the safety of the personnel under the cabinet. The setting of the clamping unit can perform adaptive clamping according to the sizes of different power supply heads, thereby improving the applicability of the device.

[0024] 5. The present invention pushes the limit sleeve rod and utilizes the fixed rod to drive the conductive rod to move upward, so that the upper conductive contact and the lower conductive contact are close to the power supply row in the clamping JP cabinet. The sliding groove and the protrusion cooperate with each other, which can not only ensure the sliding stability of the limit sleeve rod, but also limit the sliding distance of the limit sleeve rod to ensure smooth clamping and power supply. At the same time, the setting of the clamping part can use the clamping rod to clamp one of the clamping slots after the position of the conductive rod is adjusted, so as to perform one-way clamping and limiting of the conductive rod well, without the need for additional limiting operations, thereby reducing the installation burden and effectively improving the installation efficiency.

DETAILED DESCRIPTION

[0032] The present invention is described in more detail below with reference to the embodiments.

[0033] Embodiment 1

[0034] See also Figure 1 , Figure 2 and Figure 3 The JP cabinet live working power supply connection device of this embodiment includes a cabinet 1, a connector 2 is installed inside the cabinet 1, the connector 2 includes a clamping device and a connection assembly, the connection assembly includes a flexible cable 214 and a connector 215 for electrically connecting to a power supply vehicle, the connector 215 is installed at the bottom of the cabinet 1, one end of the flexible cable 214 is electrically connected to the connector 215, and the other end is electrically connected to the clamping device, the clamping device is detachably installed on the power supply element inside the cabinet 1, when it is necessary to power the cabinet 1, the power supply head of the power supply vehicle can be plugged into the connector 215, and the cabinet can be powered by the power supply vehicle 1 to prevent affecting the electricity use of residents, by installing the connector 215 at the bottom of the cabinet 1, the power supply head of the power supply vehicle can be directly plugged into the bottom of the cabinet 1 after the operator climbs up the climbing ladder, and there is no need to open the JP cabinet, which greatly saves installation time and improves work efficiency.

[0035] Among them, an auxiliary installation mechanism 3 fixedly installed on the outside of the cabinet 1 is provided at the bottom end of the connecting head 215, and the auxiliary installation mechanism 3 includes a clamping assembly for clamping the power supply head of the power supply vehicle and a driving assembly for driving the clamping assembly. The setting of the auxiliary installation mechanism 3 can assist the operator to clamp the power supply head of the power supply vehicle and align it with the connecting head 215 when climbing, which can further improve the installation efficiency. Moreover, since the JP cabinet is generally set at a relatively high position, and the connecting head 215 is set at the bottom of the cabinet 1, the climbing operators do not have a good fulcrum when climbing the ladder. Furthermore, through the setting of the auxiliary installation mechanism 3, the operators can save effort and be safer when connecting the power supply head of the power supply vehicle, effectively reducing the operation risk.

[0036] In particular, for the JP cabinet that has been put into use, the operator can also install it in the JP cabinet through the connector 2. When the power supply vehicle is needed, the JP cabinet that has been put into use can also perform power supply operations without opening the cabinet, which is suitable for promotion and use.

[0037] From the above description, it can be seen that the beneficial effect of the present invention lies in that by electrically connecting one end of the flexible cable 214 to the connector 215 and the other end to the clamping device, the design of the flexible cable 214 can provide a certain range of motion, so that the clamping device can be flexibly installed on the power supply element inside the cabinet 1, and can be adapted to JP cabinets of different sizes. At the same time, the clamping device can be installed detachably and can be replaced and maintained at any time, thereby improving the versatility and adaptability of the device.

[0038] When the operator climbs up, the auxiliary installation mechanism 3 can assist in clamping the power supply head of the power supply vehicle and aligning it with the connector 215, further improving the installation efficiency. Since the JP cabinet is generally set at a relatively high position and the connector 215 is set at the bottom of the cabinet body 1, the auxiliary installation mechanism 3 can make it easier and safer for the operator to connect the power supply head of the power supply vehicle, effectively reducing the operation risk. When the operator's hand strength is insufficient or the operation is unstable at a height, the auxiliary installation mechanism 3 can provide additional clamping and fixation for the power supply head of the power supply vehicle, ensuring that the power supply head of the power supply vehicle and the connector 215 can be accurately and firmly connected.

[0039] For the JP cabinets that are currently in use, operators can also install the device in the JP cabinets through the connector 2. When the power supply vehicle is needed, the JP cabinets that have been put into use can also be powered without opening the cabinet. That is, the device is not only suitable for newly installed JP cabinets, but also can be used to transform and upgrade existing JP cabinets. It has good compatibility and practicality and is suitable for wide promotion and use in the power system. In some JP cabinet transformation projects in old communities or remote areas, the device can be used to achieve fast and safe power supply connection, improving the reliability and flexibility of power supply.

[0040] Embodiment 2

[0041] In the JP cabinet live working power supply connection device of this embodiment, based on the above-mentioned embodiment 1, the overall mechanical structure of the auxiliary installation mechanism 3 is further defined as follows:

[0042] See also Figure 4 and Figure 5 The driving assembly includes a fixed ring 31, a sleeve ring 32 rotatably installed at the bottom end of the fixed ring 31, a rotating ring 34 installed at intervals at the bottom end of the sleeve ring 32, and a driving member 39. Specifically, three connecting blocks 33 are fixedly connected between the sleeve ring 32 and the rotating ring 34, and each connecting block 33 is evenly arranged around the center hole of the sleeve ring 32 along the circumferential direction. The driving member 39 is transmission connected to the sleeve ring 32, and the driving member 39 is used to drive the sleeve ring 32 to rotate.

[0043] The clamping assembly includes three clamping units uniformly arranged around the central hole of the fixing ring 31 along the circumferential direction. Each clamping unit is driven to clamp by a driving member 39. In this embodiment, a clamping unit is movably arranged between any two adjacent connecting blocks 33.

[0044] Specifically, the clamping unit includes an articulated cylinder 35, a swing rod 36, a sliding block 37 and a positioning round block 312. The articulated cylinder 35 is vertically fixed at the bottom end of the fixed ring 31, one end of the swing rod 36 is hinged to the bottom end of the articulated cylinder 35, and the other end of the swing rod 36 passes through the gap between the sleeve ring 32 and the rotating ring 34 and is hinged to the positioning round block 312. Specifically, in this embodiment, a U-shaped mounting groove is provided at one end of the swing rod 36 away from the articulated cylinder 35, and the positioning round block 312 is rotatably installed in the U-shaped mounting groove, wherein the sliding block 37 is slidably sleeved on the swing rod 36, and the sliding block 37 is hinged to the rotating ring 34 through a hinge pin 38, and the sliding block 37 is also provided between the sleeve ring 32 and the rotating ring 34.

[0045] Furthermore, a mounting block 313 is rotatably installed at the bottom end of the fixing ring 31, and a driving block 310 is rotatably installed on the side of the sleeve ring 32. Specifically, a hinged protrusion is integrally provided on the side of the sleeve ring 32 facing outward, and the driving block 310 and the hinged protrusion are hinged. At the same time, a transmission screw 311 is installed between the mounting block 313 and the driving block 310, and one end of the transmission screw 311 is rotatably connected to the mounting block 313, and the other end is threadedly connected to the driving block 310, and the driving member 39 is transmission-connected to the transmission screw 311.

[0046] In this embodiment, the driving member 39 is a motor, and a battery for supplying power to the motor is disposed at the bottom of the cabinet 1 .

[0047] From the above description, it can be known that the transmission screw 311 can be driven to rotate through the driving member 39, and the rotation of the transmission screw 311 can make the driving block 310 move on the transmission screw 311. While moving, the driving block 310 will drive the sleeve ring 32 to rotate through the hinge protrusion. The rotation of the sleeve ring 32 can drive the sliding block 37 to move through the hinge pin 38. Under the limiting hinge action of the hinge pin 38, the sliding block 37 drives the swing rod 36 to swing. Since the end of the swing rod 36 away from the center hole of the fixed ring 31 is hinged to the hinge tube 35, the end of the fixed swing rod 36 close to the center hole of the fixed ring 31 will swing around the hinge tube 35.

[0048] At the same time, during the rotation of the sleeve ring 32, the swing rod 36 of each clamping unit swings at a certain angle. When the three swing rods 36 swing, they drive the positioning blocks 312 to approach each other, so that the positioning blocks 312 clamp and position the power supply head of the power supply vehicle. Since the three positioning blocks 312 are approaching each other at the same time, the power supply head of the power supply vehicle can be very accurately aligned with the connector 215 to achieve auxiliary alignment installation, which is not only efficient but also safe. In addition, since the positioning blocks 312 and the swing rods are rotatably installed, when the operator places the power supply head of the power supply vehicle between the three positioning blocks 312 and tightens it, the power supply head of the power supply vehicle can also be rotated and adjusted to prevent the cable output by the power supply vehicle from being excessively wound and ensure the stability of the connection. At the same time, after the three positioning blocks 312 tighten the power supply head of the power supply vehicle, the power supply head can be prevented from falling off the ground, which can further ensure the stability of the connection and the safety of the personnel under the cabinet 1. The setting of the clamping unit can adaptively clamp according to the size of different power supply heads, thereby improving the applicability of the device.

[0049] Embodiment 3

[0050] The JP cabinet live working power supply connection device of this embodiment is based on the above-mentioned embodiment 1 or embodiment 2, and the overall mechanical structure of the connection member 2 is further defined as follows:

[0051] See also Figure 6 The clamping device includes a rectangular mounting head 21, a connecting groove 2101 is opened on the rectangular mounting head 21, an upper conductive contact 23 embedded in the rectangular mounting head 21 is arranged at the top of the connecting groove 2101, and a lower conductive contact 24 slidingly connected to the rectangular mounting head 21 is arranged at the bottom of the connecting groove 2101. The upper conductive contact 23 and the lower conductive contact 24 cooperate with each other to clamp the power supply component inside the JP cabinet.

[0052] Among them, the bottom end of the lower conductive contact 24 is fixedly connected to the conductive rod 22, and the bottom end of the conductive rod 22 slides through the rectangular mounting head 21 and is fixedly connected to the flexible cable 214. The bottom end of the rectangular mounting head 21 is provided with a pushing mechanism for pushing the lower conductive contact 24 to approach the upper conductive contact 23.

[0053] Specifically, the electric energy of the power supply vehicle is transmitted to the JP cabinet via the connecting cable, the connector 215, the flexible cable 214, the conductive rod 22, the lower conductive contact 24 and the upper conductive contact 23, and then the JP cabinet supplies power to downstream users.

[0054] The conductive rod 22 is fixedly connected to the inner wall of the limiting sleeve rod 211 through the fixing rod 213 .

[0055] Specifically, the pushing mechanism includes a limiting sleeve rod 211, a sleeve rod 26 and a clamping piece. The sleeve rod 26 is sleeved on the outside of the conductive rod 22, and the top of the sleeve rod 26 is fixedly connected to the rectangular mounting head 21. The limiting sleeve rod 211 is slidably sleeved on the bottom end of the sleeve rod 26, and the limiting sleeve rod 211 is fixedly connected to the conductive rod 22. The clamping piece is arranged on the outside of the sleeve rod 26 and is used to detachably clamp the conductive rod 22. By pushing the limiting sleeve rod 211, the conductive rod 22 can be driven to move upward, and in the process of the conductive rod 22 being pushed upward, the conductive rod 22 can be clamped by the clamping piece to achieve the limitation of the conductive rod 22.

[0056] Among them, a protrusion 261 is integrally connected to the outer side of the bottom end of the sleeve rod 26, and a sliding groove 212 adapted to the protrusion 261 is arranged inside the limiting sleeve rod 211. The protrusion 261 is slidably clamped in the sliding groove 212. The mutual matching of the protrusion 261 and the sliding groove 212 can limit the sliding distance of the sleeve rod 26 to prevent the sleeve rod 26 from detaching from the limiting sleeve rod 211.

[0057] Specifically, the clamping part includes a connecting frame 27, and a clamping rod 28 is fixedly connected to the inside of the connecting frame 27. The end of the clamping rod 28 close to the sleeve rod 26 slides through the sleeve rod 26 and is clamped with the side of the conductive rod 22. A clamping spring 29 is provided on the outer sleeve of the clamping rod 28. One end of the clamping spring 29 is fixedly connected to the sleeve rod 26, and the other end is fixedly connected to the connecting frame 27. The clamping spring 29 is used to limit the position of the clamping rod 28 to ensure that the clamping rod 28 is always in a one-way clamping state with the conductive rod 22.

[0058] Furthermore, the conductive rod 22 is provided with a plurality of slots 210 at equal intervals along the length direction to adapt to different clamping intervals, and in the present embodiment, the slots 210 are in the shape of a right-angled triangle with a horizontal top end, and the clamping end of the clamping rod 28 is provided with an inclined surface, and during the upward movement of the conductive rod 22, the bottom end of the slot 210 will contact the inclined surface of the end of the clamping rod 28, so that the clamping rod 28 is squeezed open until the clamping rod 28 enters the next slot 210, and after the conductive rod 22 stops moving, the horizontal surface at the top of the slot 210 is clamped with the top of the clamping rod 28, thereby realizing one-way limiting of the conductive rod 22.

[0059] Furthermore, the lower conductive contact 24 is slidably installed in the movable groove 2102 opened on the rectangular mounting head 21, and the outer sleeve of the conductive rod 22 is provided with a reset spring 25. The top end of the reset spring 25 is fixedly connected to the lower conductive contact 24, and the bottom end of the reset spring 25 is fixedly connected to the bottom end of the movable groove 2102. Through the setting of the reset spring 25, when the limit on the conductive rod 22 is released, the lower conductive contact 24 can quickly return to its position and quickly lose the clamping connection function, thereby improving the disassembly efficiency.

[0060] It can be seen from the above description that by pushing the limit sleeve 211 and utilizing the fixed rod 213 to drive the conductive rod 22 upward, the upper conductive contact 23 and the lower conductive contact 24 are close to the power supply row in the clamping JP cabinet, and the sliding groove 212 and the protrusion 261 cooperate with each other, which can not only ensure the sliding stability of the limit sleeve 211, but also limit the sliding distance of the limit sleeve 211 to ensure smooth clamping and power supply; at the same time, the setting of the clamping part can use the clamping rod 28 to clamp one of the clamping slots 210 after the position of the conductive rod 22 is adjusted, so as to perform one-way clamping and limiting of the conductive rod 22 well, without the need for unnecessary limiting operations, thereby reducing the installation burden and effectively improving the installation efficiency.

[0061] Working principle of the present invention: the new JP cabinet has connected the connector 2 to the power supply element in the JP cabinet when it is used out of the factory, so that the operator can connect the power supply head of the power supply vehicle and the connector 215 without opening the cabinet, so as to achieve efficient installation; at the same time, through the setting of the auxiliary installation mechanism 3, when connecting the power supply head of the power supply vehicle and the connector 215, the power supply head of the power supply vehicle can be clamped by the positioning round block 312, so as to assist the installation. Specifically, the operator starts by controlling the driving member 39, and the driving member 39 can drive the transmission screw 311 to rotate. The rotation of the transmission screw 311 can make the driving block 310 move on the transmission screw 311. While moving, the driving block 310 will drive the sleeve ring 32 to rotate through the hinged protrusion. The rotation of the sleeve ring 32 The sliding block 37 can be driven to move by the hinge pin 38, and the sliding block 37 drives the swing rod 36 to swing under the limiting hinge action of the hinge pin 38. Since the end of the swing rod 36 away from the center hole of the fixed ring 31 is hinged to the hinge tube 35, the end of the fixed swing rod 36 close to the center hole of the fixed ring 31 will swing around the hinge tube 35. At the same time, during the rotation of the sleeve ring 32, the swing rod 36 of each clamping unit swings at a certain angle. While the three swing rods 36 swing, they drive the positioning blocks 312 to approach each other, so that the positioning blocks 312 clamp and position the power supply head of the power supply vehicle. Since the three positioning blocks 312 are close to each other at the same time, the power supply head of the power supply vehicle can be very accurately aligned with the connector 215 to achieve auxiliary alignment and installation.

[0062] When facing an old JP cabinet, the operator needs to install the connector 2 first, that is, drill a hole at the bottom of the cabinet 1 and install the connector 215, and then clamp the clamping device to the terminal block inside the cabinet 1, that is, by pushing the limiting sleeve 211, use the fixing rod 213 to drive the conductive rod 22 upward, so that the upper conductive contact 23 and the lower conductive contact 24 are close to the power supply block in the clamping JP cabinet and clamped. After the position of the conductive rod 22 is adjusted, the clamping part uses the clamping rod 28 to clamp one of the slots 210 to achieve one-way clamping and limiting of the conductive rod 22, and the installation is completed.
