Description

Technical Field

[0001] This invention relates to the field of cable branch box technology, and in particular to a multifunctional buried integrated cable branch box. Background Technology

[0002] With the transformation and upgrading of urban power distribution networks, buried cable branch boxes are increasingly widely used in cable branching and splicing due to their advantages such as saving ground space and beautifying the environment.

[0003] During long-term operation, these types of distribution boxes generally face several key problems: First, the manholes or foundations where the boxes are located often experience uneven settlement due to geological changes and surrounding construction, resulting in height differences and longitudinal tension between the internal wiring terminals and the external buried cables. Existing technology lacks an effective automatic compensation mechanism, leaving cables and connectors under constant stress, which can accelerate insulation aging and even cause connectors to loosen or break, leading to power supply failures. Second, although some boxes are equipped with waterproof structures or water accumulation detection devices, their functions are mostly limited to alarms and cannot provide emergency handling when water accumulates. Third, the cables inside the boxes are usually directly laid or simply fixed, lacking real-time monitoring of cable morphology, making early warning difficult in the early stages of deformation, and maintenance relies on manual inspections, which are not timely enough. Therefore, we propose a multi-functional buried integrated cable distribution box. Summary of the Invention

[0015] Beneficial effects

[0016] This invention provides a multifunctional buried integrated cable branch box. It has the following advantages:

[0017] (1) The multi-functional buried integrated cable branch box lifts two second connecting rods upward through the winding assembly, so that the two slides connected to the second connecting rods are lifted upward. Then, the branch terminal is lifted upward as a whole through four first connecting rods. By lifting the branch terminal upward, the height difference between the cable inside the cable branch box and the buried cable caused by land subsidence is compensated, thereby eliminating the deformation caused by the cable under stress. This can effectively solve the problem of cable pulling and power failure caused by the deformation of the cable after long-term use. At the same time, it can also avoid cracking at the connection between the cable and the joint due to deformation and aging.

[0018] (2) The multi-functional buried integrated cable branch box detects whether there is water accumulation at the bottom of the cable branch box through the probe bracket water leakage and water immersion sensor. If water accumulation occurs at the bottom of the cable branch box, the signal of water accumulation is transmitted to the control room. Similarly, the branch terminal can be lifted upward by the winding component as an emergency treatment to avoid the bottom surface of the branch terminal from contacting the water accumulation, thus giving the staff time to carry out emergency repairs inside the cable branch box. Therefore, the cable branch box can not only realize the alarm function, but also carry out emergency treatment inside it.

[0019] (3) The multi-functional buried integrated cable branch box supports the cable with a support rod, which on the one hand prevents the cable from touching the bottom of the cable branch box, and on the other hand can detect the cable when it is deformed, and then transmit the detection signal to the control room, so that the staff can make timely judgments on the condition of the cable branch box and carry out maintenance.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1 - Figure 8As shown, a multifunctional buried integrated cable branch box includes a cable branch box body 1. A branch terminal 10 is installed inside the cable branch box body 1. Connectors 11 are fixedly installed on the outer walls of both ends of the branch terminal 10. Cables 12 are connected to the ends of the connectors 11. Through holes are opened on the outer walls of both ends of the cable branch box body 1, through which the ends of multiple cables 12 extend to the outside of the cable branch box body 1. An installation groove is opened at the upper end of the cable branch box body 1. Two sets of symmetrically arranged lifting components 15 are movably installed at both ends of the installation groove. Each lifting component 15 includes two first rotating frames 1501 rotatably connected to the inner wall of the installation groove. A second connecting rod 1502 is fixedly connected to the free ends of the two first rotating frames 1501. Two sets of symmetrically arranged traction components 8 are connected below the two second connecting rods 1502. 8 specifically includes a slide 801, with a first slider 802 slidably connected to both ends of the upper surface of the slide 801. A second connecting ring 803 is fixedly installed on the upper end face of the first slider 802. The second connecting ring 803 is rotatably connected to the outer wall of the second connecting rod 1502. The bottom surfaces of the two slides 801 and the four corners of the upper surface of the branch terminal 10 are fixedly installed with first connecting rods 804. The ends of the first connecting rods 804 are fixedly connected to the upper surface of the branch terminal 10. Limiting components 9 are provided inside the mounting groove and at positions corresponding to the free ends of the first rotating frame 1501. A winding component 7 for lifting the second connecting rod 1502 upward is also provided on the upper surface of the cable branch box 1. Detection components 16 are respectively provided inside the cable branch box 1 at positions corresponding to the cable 12. There are two sets of detection components 16.

[0034] If localized settlement occurs at the location of the cable branch box 1, multiple cables 12 will deform under stress. External force will then lift two second connecting rods 1502 upwards. One end of the first rotating frame 1501 is rotatably connected to the inner wall of the mounting groove, while the other end is defined as the free end. The second connecting rods 1502 are fixed between the free ends of the two first rotating frames 1501. Two traction components 8 located below the two second connecting rods 1502 move upwards synchronously with the second connecting rods 1502. Then, four first connecting rods 804 lift the branch terminal 10 upwards as a whole. Based on the depth of settlement at the bottom of the cable branch box 1, lifting the branch terminal 10 upwards compensates for the height difference between the cables 12 inside the cable branch box 1 and the buried cables 12 caused by land settlement. This eliminates the deformation of the cables 12 under stress, effectively solving the problem of cable traction and power loss caused by deformation of the cables 12 over long-term use. It also prevents cracking at the connection between the cables 12 and the connector 11 due to deformation and aging.

[0035] As a technical optimization of the present invention, the winding assembly 7 includes a traction rope 703, and a first connecting ring 704 is fixedly installed at both ends of the traction rope 703. The first connecting ring 704 is rotatably connected to the outer wall of the second connecting rod 1502. The second connecting rod 1502 only rotates on the outer wall of the first connecting ring 704 near its two ends, without relative sliding.

[0036] As a technical optimization of the present invention, a third cover plate 4 is fixedly installed at the center of the upper surface of the cable branch box 1. A rectangular groove is opened through the third cover plate 4. The winding assembly 7 also includes a mounting base 701 fixedly installed on the upper surface of the third cover plate 4. A winding cylinder 702 is rotatably installed inside the mounting base 701. The middle position of the traction rope 703 is fixedly connected to the outer wall of the winding cylinder 702. The traction rope 703 extends outward from the rectangular groove opened on the third cover plate 4 and is fixedly connected to the outer wall of the winding cylinder 702. When the winding cylinder 702 rotates, the traction rope 703 can be wound from the middle section, and the overall length of the traction rope 703 becomes shorter. The two ends of the traction rope 703 are connected to the second connecting rod 1502. During the process of the traction rope 703 becoming shorter, the second connecting rod 1502 can be lifted upward.

[0037] As a technical optimization of the present invention, a docking block 6 is rotatably mounted on the outer wall of the mounting base 701 and the end of the winding cylinder 702, and the docking block 6 is fixedly connected to the center position of the outer wall of the end of the winding cylinder 702; the docking block 6 and the outer wall of the end of the winding cylinder 702 are fixedly connected by a cylindrical shaft, and the cylindrical shaft is rotatably connected to the upper end of the mounting base 701, and the winding cylinder 702, the cylindrical shaft and the docking block 6 are coaxially arranged, so that the winding cylinder 702 can be synchronously driven to rotate under the connection of the cylindrical shaft by driving the docking block 6 to rotate.

[0038] As a technical optimization of the present invention, the upper surface of the cable branch box 1 is fitted with first cover plates 2 on both sides of the third cover plate 4, and the two first cover plates 2 are rotatably fitted with second cover plates 3 on the side away from the third cover plate 4. The staff can observe the internal situation of the cable branch box 1 by flipping the second cover plate 3. After the second cover plate 3 is flipped open, the staff can also manually adjust the limiting component 9 according to the actual situation.

[0039] As a technical optimization of the present invention, each detection assembly 16 includes two second rotating frames 1601 fixedly connected to the inner wall of the upper end of the cable branch box 1. Detection frames 1602 are fixedly connected to the ends of the two second rotating frames 1601. Limiting grooves 1604 are opened through both sides of the detection frames 1602. A second slider 1603 is slidably connected inside the detection frame 1602, and the two sides of the second slider 1603 slide inside the limiting grooves 1604 respectively. A second spring 1605 is provided inside the limiting grooves 1604 below the second slider 1603. The second slider 1603 has a T-shaped structure, and the two sides of the upper end of the second slider 1603 slide inside the limiting grooves 1604, which can prevent the second slider 1603 from falling out of the detection frame 1602. During the sliding process of the second slider 1603, the second spring 1605 is squeezed simultaneously.

[0040] As a technical optimization of the present invention, one end of the second spring 1605 is fixedly connected to the bottom surface of the second slider 1603. The bottom surface of the limiting groove 1604 is located at the lower end of the second spring 1605 and a pressure sensor 1606 is fixedly installed thereon. The lower end of the second spring 1605 is fixedly connected to the output end of the pressure sensor 1606. A pull rod 13 is also fixedly installed on the bottom surface of the second slider 1603. The upper end of the pull rod 13 is also located inside the detection frame 1602 and slides. A support rod 14 is fixedly installed at the lower end of the pull rod 13. When the support rod 14 is subjected to force, it drives the upper end of the pull rod 13 to slide inside the detection frame 1602. The second slider 1603, which is fixed at the upper end of the pull rod 13, slides synchronously, which can change the force on the second spring 1605. The lower end of the second spring 1605 contacts the output end of the pressure sensor 1606. The change in the force on the support rod 14 can cause a change in the value of the pressure sensor 1606.

[0041] As a technical optimization of the present invention, the number of support rods 14 is multiple sets, and the multiple sets of support rods 14 are respectively located below the cable 12 and in contact with the cable 12; the specific number of support rods 14 depends on the number of rows of multiple cables 12, and a single support rod 14 can support multiple cables 12 located on the same horizontal line.

[0042] As a technical optimization of the present invention, a protective box 5 is provided on the upper surface of the third cover plate 4 outside the winding cylinder 702. The lower end of the protective box 5 is fixedly connected to the upper surface of the third cover plate 4 by bolts. A circular hole is provided through the outer wall of the end of the protective box 5 at the corresponding position of the docking block 6. The circular hole exposes the docking block 6, making it easy for the operator to drive the docking block 6 to rotate after combining the tool with the docking block 6. The protective box 5 can protect the exterior of the mounting base 701 and the winding cylinder 702, and can also ensure that the top of the cable branch box 1 is in a relatively closed state, preventing debris from entering the interior of the cable branch box 1 through the rectangular groove opened on the third cover plate 4.

[0043] As a technical optimization of the present invention, the limiting component 9 specifically includes a limiting block 901. Multiple first springs 902 are fixedly connected to the outer wall of the limiting block 901, and the other end of the first springs 902 is fixedly connected to the inner wall of the mounting groove. When the second connecting rod 1502 is lifted upward under the action of external force, the multiple first springs 902 push the limiting block 901 downward towards the free end of the first rotating frame 1501, and the inclined surface of the limiting block 901 can support the free end of the first rotating frame 1501.

[0044] Working principle of the invention:

[0045] In use, the cable branch box 1 is buried below ground. The protective box 5 and the mounting base 701 and winding cylinder 702 inside it are exposed above ground. The pull rod 13 and support rod 14 installed inside the cable branch box 1 can support multiple cables 12 coming out from the branch terminal 10. The specific number of support rods 14 depends on the number of rows of multiple cables 12. A single support rod 14 can support multiple cables 12 located on the same horizontal line, preventing the cables 12 from touching the bottom surface of the cable branch box 1, and thus preventing the cables 12 from contacting the water inside the cable branch box 1 when water enters the cable branch box 1.

[0046] After prolonged use, if localized settlement occurs at the cable branch box 1, multiple cables 12 will deform under stress. Since the cables 12 are large-diameter cables, this deformation will cause changes in the stress on the support rods 14. The support rods 14 are fixedly connected to the pull rod 13, which in turn is fixedly connected to the second slider 1603. The second slider 1603 then acts on the pressure sensor 1606 via the second spring 1605. The pressure sensor 1606 can be made of SMC material. PSE530: When the force on the support rod 14 changes, it indirectly causes a change in the reading of the pressure sensor 1606. After the change in the pressure sensor 1606 is transmitted to the control room, the operator can use external tools to connect with the docking block 6 and drive the winding drum 702 to rotate. The middle position of the traction rope 703 is fixedly connected to the outer wall of the winding drum 702. When the winding drum 702 rotates, the length of the traction rope 703 is shortened. The traction rope 703 lifts the two second connecting rods 1502 upwards. The two slides 801 located below the two second connecting rods 1502 are connected to the second... The connecting rod 1502 moves upward synchronously, and then the branch terminal 10 is lifted upward as a whole through the four first connecting rods 804. The depth of the bottom settlement of the cable branch box 1 is inferred based on the value change of the pressure sensor 1606. Then, by lifting the branch terminal 10 upward, the height difference between the cable 12 inside the cable branch box 1 and the buried cable 12 caused by the land settlement is compensated, thereby eliminating the deformation caused by the cable 12 under stress. This can effectively solve the problem of cable traction and power failure caused by the deformation of the cable 12 after long-term use. At the same time, it can also prevent the connection between the cable 12 and the connector 11 from cracking due to deformation and aging.

[0047] The bottom of the cable branch box 1 is equipped with a probe bracket water leakage sensor to detect whether there is water accumulation at the bottom of the cable branch box 1. The probe bracket water leakage sensor is existing technology and will not be described in detail here. If water accumulates at the bottom of the cable branch box 1, the signal is transmitted to the control room. The rewind assembly 7 can then drive the branch terminal 10 upwards as an emergency measure to prevent the bottom of the branch terminal 10 from contacting the water, thus buying time for the staff to carry out emergency repairs inside the cable branch box 1.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
