Technical Field
[0001] This utility model relates to the field of hub box technology, and in particular to a hub box data acquisition device. Background Technology
[0002] A junction box is a specialized enclosure widely used in building wiring, industrial equipment, data centers, communication networks, and smart homes. Its main function is to provide centralized physical containment, orderly organization, security protection, and standardized access points for various cables. As the core node of a cable management system, the junction box protects internal cables and connecting devices from the influence of the external environment through its enclosed or semi-enclosed enclosure structure. At the same time, it uses the internal pre-set cable management structure or mounting rails to gather and fix incoming and outgoing cables, effectively avoiding messy distribution and tangling of cables.
[0003] However, in special scenarios such as hydropower stations, their protective effectiveness faces severe challenges. After the completion of hydropower station construction tunnels, vehicles cannot enter due to muddy roads and deteriorating traffic conditions, forcing the maintenance and monitoring of traditional junction boxes to rely on manual operation. For example, after multiple cable theft incidents at the Gudi and Xinzang hydropower stations, maintenance personnel had to walk several kilometers to reach the tunnel end for data collection. Each operation was time-consuming, and the complex internal environment of the tunnel made it difficult for staff to collect information. Summary of the Invention

[0032] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0033] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0034] Reference Figures 1-5This embodiment provides a data acquisition device for a junction box, including a box 1, in which various electrical devices are installed in a hollow interior; a monitoring unit 2, which is installed inside the box 1; a transmission unit 3, which is connected to the monitoring unit 2 via a wire; and a clamping unit 4, including a fixing frame 41 fixedly installed inside the box 1, an elastic clamp 45 disposed on the end face of the fixing frame 41, and a pressure plate 44 disposed inside the elastic clamp 45.
[0035] It should be noted that the enclosure 1 is made of thin metal sheet, manufactured through bending, stamping and other processing techniques; and the interior of the enclosure 1 is hollow to ensure that electrical components, including relays, circuit breakers, electricity meters, etc., can be installed inside the enclosure 1; the monitoring unit 2 can be a high-frequency current transformer or a zero-sequence current sensor or other cable condition monitoring equipment, so as to monitor the signals of the cables inside the junction box.
[0036] The monitoring unit 2 and the transmission unit 3 are connected by a wire. The transmission unit 3 can organize and analyze the information monitored by the monitoring unit 2 and convert it into obvious digital signals, light signals, etc., and transmit them to the staff. The transmission unit 3 can also transmit signals to the staff wirelessly. In places where wireless signal transmission is difficult, signals can be transmitted through wires to ensure that the staff outside the branch tunnel can understand the working status of the cables in the junction box inside the branch tunnel.
[0037] It should be noted that the fixing frame 41 is a metal plate structure, and the two ends of the fixing frame 41 are bent inward to form a U-shaped structure; the fixing frame 41 is fixedly connected to the box 1, and the fixing frame 41 and the box 1 can be fixedly connected by welding; the surface of the fixing frame 41 is provided with an elastic clamp 45, which has a certain elastic deformation; under normal conditions, the open end of the elastic clamp 45 is brought together towards the middle to ensure that the diameter of the open end of the elastic clamp 45 is small, so that the open end of the elastic clamp 45 can penetrate into the inside of the monitoring unit 2; then the pressure plate 44 can be used to expand the open end of the elastic clamp 45, so that the outer wall of the elastic clamp 45 can be tightly attached to the inner wall of the monitoring unit 2, thereby realizing the clamping and fixing of the monitoring unit 2.
[0038] Reference Figures 1-3 In one embodiment provided in this application, a guide sleeve 42 is installed on the inner side of the fixing frame 41, and the guide sleeve 42 is fixedly connected to the fixing frame 41; the end of the guide sleeve 42 penetrates the surface of the fixing frame 41 and extends to its outer side.
[0039] It should be noted that the guide sleeve 42 is a tubular structure with an open top, and the guide sleeve 42 is installed and fixed to the fixing frame 41 by bolts and nuts. The end of the guide sleeve 42 penetrates the surface of the fixing frame 41 and extends to its outer side.
[0040] Specifically, the guide sleeve 42 is installed inside the loop-shaped structure of the fixed frame 41.
[0041] Furthermore, a push rod 43 is sleeved inside the guide sleeve 42; the push rod 43 is connected to the pressure plate 44, the pressure plate 44 passes through the elastic clamp 45 and extends to its inner side; the pressure plate 44 can squeeze the elastic clamp 45 and make it expand outward.
[0042] It should be noted that the guide sleeve 42 is adapted to the push rod 43, the axis of the push rod 43 coincides with that of the guide sleeve 42, one end of the push rod 43 is connected to the pressure plate 44, and while the push rod 43 moves along the axis of the guide sleeve 42, it also drives the pressure plate 44 to move in the vertical direction.
[0043] Specifically, when the position between the elastic clamp 45 and the fixed frame 41 is fixed, the pressure plate 44 is pushed to move towards the open end of the elastic clamp 45. The pressure plate 44 can squeeze the elastic clamp 45 to make the end of the elastic clamp 45 open, so that the outer wall of the elastic clamp 45 abuts against the inner wall of the monitoring unit 2, thereby fixing the position between the elastic clamp 45 and the monitoring unit 2.
[0044] Furthermore, the push rod 43 includes a piston head 431 disposed at its end, the piston head 431 being away from the pressure plate 44; the piston head 431 is located inside the guide sleeve 42, and the piston head 431 and the inner wall of the guide sleeve 42 cooperate to form a cavity 421; a plug 422 is provided at the open end of the guide sleeve 42, and the push rod 43 passes through the plug 422 and extends to its outer side.
[0045] It should be noted that the piston head 431 and the push rod 43 are connected and fixed by a positioning pin, and a sealing gasket is provided on the outer wall of the piston head 431. The sealing gasket can ensure tight contact between the piston head 431 and the inner wall of the guide sleeve 42. When affected by vibration, the piston head 431 moves inside the guide sleeve 42, which can convert kinetic energy into potential energy, thereby effectively preventing the push rod 43 from shaking.
[0046] To further ensure the tight connection between the push rod 43 and the guide sleeve 42, a plug 422 is provided at the open end of the guide sleeve 42, and the plug 422 is adapted to the outer wall of the push rod 43. When the push rod 43 is affected by external force and moves along the axis of the guide sleeve 42, the plug 422 can limit the push rod 43.
[0047] Specifically, the piston head 431 and the inner wall of the guide sleeve 42 form a cavity 421. When the push rod 43 moves in the vertical direction, the piston head 431 will squeeze the space inside the cavity 421 and compress the air inside the cavity 421, thereby converting kinetic energy into potential energy. Specifically, the piston head 431 squeezes the air inside the cavity 421, causing the tube wall of the guide sleeve 42 to heat up.
[0048] Reference Figures 1-6In some embodiments, the elastic clamp 45 includes multiple sets of notches 452 formed on its side wall, and a bending groove 451 formed around the inner circumference of the elastic clamp 45; the elastic clamp 45 is sleeved inside the monitoring unit 2, and the outward expansion of the elastic clamp 45 can fix the monitoring unit 2.
[0049] It should be noted that the sidewall of the elastic chuck 45 has multiple sets of notches 452, and the notches 452 can ensure that the elastic chuck 45 has sufficient deformation space to meet the requirement of the sidewall of the elastic chuck 45 being deformed by compression.
[0050] Specifically, a bending groove 451 is provided at the bottom of the elastic clamp 45. When the elastic clamp 45 is squeezed by the outer wall of the pressure plate 44, the elastic clamp 45 bends along the bending groove 451, thereby opening the open end of the elastic clamp 45. Under normal conditions, the open end of the elastic clamp 45 converges towards the open end along the bending groove 451. Under normal conditions, the diameter of the elastic clamp 45 is smaller than the inner diameter of the monitoring unit 2.
[0051] Furthermore, the pressure plate 44 has a conical structure, and the outer wall of the pressure plate 44 abuts against the inner wall of the elastic clamp 45; the movement of the pressure plate 44 along the axis of the elastic clamp 45 can push the elastic clamp 45 to expand in all directions.
[0052] It should be noted that the pressure plate 44 has a conical structure, which can further reduce the volume of the pressure plate 44, thereby reducing the manufacturing cost of the pressure plate 44.
[0053] As the pressure plate 44 moves along the axis of the push rod 43, the outer wall of the pressure plate 44 will press against the inner wall of the elastic clamp 45, thereby causing the side wall of the elastic clamp 45 to bend along the bending groove 451. While the opening end of the elastic clamp 45 expands outward, the outer wall of the elastic clamp 45 abuts against the inner wall of the monitoring unit 2, which can fix the position between the elastic clamp 45 and the monitoring unit 2.
[0054] Furthermore, an elastic element 46 is sleeved on the outer side of the push rod 43; one end of the elastic element 46 abuts against the fixed frame 41, and the other end abuts against the elastic clamp 45.
[0055] It should be noted that the elastic element 46 is preferably a spring, and the spring is disposed on the outer wall of the push rod 43. One end of the spring abuts against the fixed frame 41, and the other end abuts against the elastic clamp 45.
[0056] In use, to ensure that the elastic clamp 45 is in the contracted state, the pressure plate 44 needs to be pushed so that the end of the pressure plate 44 abuts against the bottom of the elastic clamp 45. While the pressure plate 44 is pressed down, the elastic clamp 45 can be moved synchronously. As the elastic clamp 45 moves, the elastic element 46 can be compressed, thus putting the elastic element 46 into a compressed and stored energy state. While the pressure plate 44 is moving, it can also drive the push rod 43 to move, so that the piston head 431 compresses the air inside the cavity 421. When the pressure plate 44 abuts against the end of the elastic clamp 45, the monitoring unit 2 can be fitted onto the outer wall of the elastic clamp 45. Then, the hand pressing the pressure plate 44 is released, and under the elastic force of the elastic element 46, the elastic clamp 45 is pushed back to its original position. At the same time, the piston head 431 is pushed by the air inside the cavity 421, which also pushes the pressure plate 44 to move, so that the pressure plate 44 moves away from the bottom surface of the elastic clamp 45, thereby causing the side wall of the elastic clamp 45 to expand outward, which can fix the monitoring unit 2 on the outer wall of the elastic clamp 45.
[0057] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
[0058] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
