Description

Technical Field

[0001] The invention belongs to the field of distribution boxes, and in particular relates to an outdoor distribution box. Background Art

[0002] The distribution box is a device responsible for completing the control, protection, conversion and distribution of electric energy at the end of low-voltage power supply, and plays an important role in protecting the line from short circuit, leakage, overload, etc. The distribution box includes a box body, inside which are electrical components such as switchgear, measuring instruments, protective electrical appliances and auxiliary equipment.

[0003] Some distribution boxes used outdoors need to be installed on electric poles (telephone poles). When installing a distribution box on a pole, workers usually use ladders and other tools to climb to the top of the pole, and then use pipe clamps, bolts, nuts and other fasteners to install the distribution box on the pole. After the distribution box is installed, wiring is required. The distribution box generally supplies power to a variety of equipment, so the distribution box is generally designed for multi-circuit power supply. When wiring, workers usually climb to a high place holding multiple external wires, and then extend the multiple external wires from the bottom of the distribution box to the inside of the distribution box.

[0004] From the above introduction, it can be seen that in conventional means, the installation of the distribution box on the pole and the wiring operation of connecting the external wiring to the distribution box both require workers to work at height, which is difficult in actual operation and also poses a safety hazard. Summary of the invention

[0011] As a further improvement, one of the wire and the outer conductive ring is connected to a plug, and the other is connected to a socket, so that the conductive connection between the wire and the outer conductive ring is achieved through the plug-in fit of the plug and the socket.

[0012] As a further improvement, the external wire connection structure also includes a buckle structure to lock the plug and the socket through the buckle structure.

[0013] As a further improvement, a door is hinged on the box body, and the hinge axis of the door extends vertically. A door linkage mechanism is also connected between the door and the cable winding roller. The door linkage mechanism includes a movable component that can move relative to the box body to drive the door to open and close. The movable component is connected to the cable winding roller through a reversing connection structure so as to move with the rotation of the cable winding roller. The movable stroke of the movable component satisfies the requirement that the door be closed when the box body climbs to the set position along the pole.

[0014] As a further improvement, the reversing connection structure includes a second worm connected to the cable winding roller for rotation prevention, a second worm wheel meshing with the second worm, and a threaded sleeve connected to the second worm wheel for rotation prevention, and the movable part is connected to a screw threadedly connected to the threaded sleeve.

[0015] As a further improvement, the outdoor distribution box is also equipped with an auxiliary winding mechanism located below the cable winding roller. The auxiliary winding mechanism includes a rotatable first auxiliary roller and a second auxiliary roller. The first auxiliary roller and the second auxiliary roller are arranged at intervals, and the space between the two is for the external wiring to pass through. When the cable winding roller winds the cable, the first auxiliary roller and the second auxiliary roller rotate synchronously.

[0016] As a further improvement, one of the first auxiliary roller and the second auxiliary roller is drivingly connected to the cable winding roller so as to rotate synchronously with the cable winding roller.

[0020] The present invention pioneers a distribution box that can automatically climb poles and reel in external wires, and its beneficial effects are: when the distribution box is in use, the external wires and electrical components can be connected on the ground through the external wire connection structure, and then the first bracket and the second bracket are buckled and connected and hold the pole tightly, and the drive motor is started. The distribution box can automatically climb up the pole through the first main climbing roller and the second main climbing roller in the self-climbing mechanism.

DETAILED DESCRIPTION

[0023] In order to facilitate the installation of the distribution box and the external wiring, the basic technical concept of the present invention is to provide a distribution box that can automatically climb the pole and reel in the external wiring. Specifically, a self-climbing pole mechanism that can automatically move along the pole to drive the distribution box to climb as a whole is connected to the box body, the external wiring and the electrical components in the box body are connected on the ground, and a cable reeling mechanism that can automatically reel in the cable during the climbing process of the distribution box is configured. Based on the above concept, the present invention is further described in detail below in combination with some embodiments.

[0024] The specific embodiment of the outdoor distribution box provided by the present invention is as follows: like Figure 1-Figure 9 As shown, the distribution box includes a box body 2, and an electrical component 14 is arranged inside the box body 2. Specifically, the electrical component 14 can be one or a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment, which is not limited here. The box body 2 is connected to a self-climbing pole mechanism, and the self-climbing pole mechanism includes a first bracket 3 and a second bracket 4. The first bracket 3 and the second bracket 4 are used to be interlocked and connected to each other to hold the pole tightly (not shown in the figure). Specifically, a rotatable first main climbing roller 38 is installed on the first bracket 3, and a rotatable second main climbing roller 43 is installed on the second bracket 4. The main climbing roller refers to a climbing roller that can be actively rotated to fit and climb up and down along the pole. The first main climbing roller 38 and the second main climbing roller 43 rotate in opposite directions, that is, they rotate in opposite directions.

[0025] In order to realize the rotation of the first main climbing roller 38 and the second main climbing roller 43, the distribution box is also equipped with a drive motor 382 as a power source. It should be noted that the figure shows an exemplary preferred embodiment in which the same drive motor 382 drives the first main climbing roller 38 and the second main climbing roller 43 to rotate in opposite directions. Specifically, the power output shaft of the drive motor 382 is connected to one of the first main climbing roller 38 and the second main climbing roller 43. More specifically, as shown in FIG. Figure 6 As shown, the power output shaft of the drive motor 382 is connected to the fifth gear 383, and the first main climbing roller 38 is connected to the sixth gear 384, and the fifth gear 383 and the sixth gear 384 are meshed and driven. Of course, in other embodiments, the power output shaft of the drive motor 382 can also be connected to one of the first main climbing roller 38 and the second main climbing roller 43 through a coupling. The first main climbing roller 38 and the second main climbing roller 43 are connected through a spur gear mechanism, and the spur gear mechanism here includes a first gear 32 and a second gear 42. Compared with configuring a separate motor as a drive for each main climbing roller, this embodiment can save space (generally speaking, the volume of the gear is smaller than that of the motor), and it is also easy to ensure that the rotation speeds of the two main climbing rollers remain synchronized.

[0026] By configuring a self-climbing pole mechanism, this embodiment can achieve automatic climbing and descending along the pole, eliminating the need for workers to climb up to install the distribution box, making it more convenient to use.

[0027] The electrical component 14 is connected to an external wiring connection structure for conducting connection with an external wiring (not shown in the figure). The staff can complete the connection between the external wiring and the electrical component 14 on the ground without holding the external wiring to climb the height.

[0028] In addition, the distribution box is also equipped with a cable reel mechanism, which includes a rotatable cable reel 55, and the cable reel 55 is used to reel in the external wires that are conductively connected to the electrical components 14. Figure 1-Figure 3 and Fig. 9 As shown, the cable winding mechanism can be installed below the first bracket 3, specifically comprising a bottom box 5, the upper and lower ends of the bottom box 5 are open structures, and the cable winding roller 55 is installed on the bottom box 5. In order to facilitate cable winding, a winding wheel 56 can be installed on the cable winding roller 55.

[0029] By configuring the cable reeling mechanism, when climbing up the pole, the embodiment can reel in the longer external wires by the cable reeling roller 55, thus preventing the longer external wires from being exposed. When maintenance is required later, when the distribution box descends along the pole, the external wires can be released by the cable reeling roller 55, without releasing the connection between the external wires and the electrical components 14, which is also convenient for subsequent maintenance operations.

[0030] As a preferred embodiment, the same drive motor 382 can also be used as a power source to drive the cable winding roller 55 to rotate. From a structural perspective, one of the first main climbing roller 38 and the second main climbing roller 43 can be connected to the cable winding roller 55 through a transmission connection structure, thereby synchronously driving the cable winding roller 55 to rotate.

[0031] Specifically, as an implementation method of a transmission connection structure, Figure 1 , Figure 6 , Figure 8 , Fig.12 As shown, the transmission connection structure includes a first worm wheel 381 that is non-rotatably connected to the first main climbing roller 38, a first worm 37 that is meshed with the first worm wheel 381, a first bevel gear 385 that is non-rotatably connected to the first worm 37, and a second bevel gear 54 that is non-rotatably mounted on the cable winding roller 55 and meshed with the first bevel gear 385. This transmission connection structure has a self-locking effect, which can prevent the cable winding roller 55 from accidentally loosening. It is also convenient for long-distance transmission and is suitable for larger distribution boxes. Of course, since the cable winding roller 55 is parallel to the first main climbing roller 38, if the space is sufficient, in other embodiments, the transmission connection structure is not excluded as a support wheel.

[0032] As a preferred embodiment, Figure 2 , Figure 3 , Figure 9-11 As shown, the external wiring connection structure includes a wire 511 drawn from the electrical component 14 and passing through the box 2. The number of wires 511 is not specifically limited and can be flexibly set according to the actual circuit. Accordingly, the box 2 is provided with a through hole for the wire 511 to pass through. The through hole can be a long hole, and multiple wires 511 pass through the same long hole. In order to ensure the airtightness of the box 2, a rubber strip 15 is provided in the long hole to play a sealing role.

[0033] The wire 511 is conductively connected to an outer conductive ring 562, which is fixed relative to the box body 2 and can be specifically installed on the bottom box 5. The cable winding roller 55 is provided with an inner conductive ring 561 located inside the outer conductive ring 562 and conductively connected to the outer conductive ring 562, and the inner conductive ring 561 is used to be conductively connected to the external wire. Compared with the way in which the external wire is directly connected to the wire 511, the terminal of the external wire is actually connected to the cable winding roller 55, which is convenient for the winding of the external wire and will not affect the wire 511. The connection method of the terminal of the external wire and the inner conductive ring 561 is not specifically limited here, and ordinary technicians in this field can flexibly select the installation method according to actual conditions. For example, a channel for the terminal of the external wire to penetrate can be set on the winding wheel 56, and the terminal of the external wire can penetrate the channel and be conductively connected to the inner periphery of the inner conductive ring 561. For another example, in the radial direction, the inner conductive ring 561 can be made to protrude from the winding wheel 56, and the external wire is conductively connected to the protruding end position of the inner conductive ring 561.

[0034] To facilitate the conductive connection between the wire 511 and the outer conductive ring 562, as a more preferred embodiment, Fig.10 and Fig.11 As shown, the outer conductive ring 562 is conductively connected to the socket 52 (the terminal of the socket 52 at one end away from the plug end is in contact with the outer conductive ring 562), and one end of the wire 511 is connected to the plug 51, and the connection between the wire 511 and the outer conductive ring 562 can be achieved by plugging and matching the plug 51 and the socket 52. Of course, the positions of the plug 51 and the socket 52 can also be interchanged, that is, the socket 52 is connected to the wire 511, and the plug 51 is connected to the outer conductive ring 562.

[0035] On the basis of the above preferred embodiments, in order to make the connection between the plug 51 and the socket 52 more reliable, the external wire connection structure further includes a buckle structure 53, so as to lock the plug 51 and the socket 52 through the buckle structure 53. The buckle structure 53 has a certain elasticity, and can buckle the plug 51 after the plug 51 and the socket 52 are plugged and matched.

[0036] In order to prevent the box door 1 from accidentally opening when the distribution box moves up and down, as a preferred embodiment, a door 1 linkage mechanism is also connected between the box door 1 and the cable winding roller 55. Specifically, Figure 1 As shown, the door 1 is hinged on the box body 2, and the hinge axis of the door 1 extends vertically. The door 1 linkage mechanism includes a movable part that can move relative to the box body 2 to drive the door 1 to open and close. Specifically, the movable part in this embodiment includes a slider 12 slidably mounted on the box body 2 and a movable block hinged to the slider 12. The slider 12 moves in a vertical direction. Figure 1 The left side of the box can push the box door 1 to rotate in the direction close to the box body 2, and then close the box door 1. The movable part is connected to the cable winding roller 55 through the reversing connection structure, so that the opening and closing of the box door 1 are linked with the winding process of the external wire. In this process, the moving stroke of the movable part satisfies that when the box body 2 climbs to the set position along the pole, the box door 1 is just closed, which can be achieved by matching the transmission ratio of the reversing connection structure.

[0037] As a preferred embodiment of the reversing connection structure, Figure 1-4 , Fig. 9 , Figure 13-14As shown, the reversing connection structure includes a second worm 57 connected to the cable winding roller 55 for rotation prevention, a second worm wheel 33 meshing with the second worm 57 for transmission, and a threaded sleeve 34 connected to the second worm wheel 33 for rotation prevention. The movable part is connected to a screw 13 threadedly connected to the threaded sleeve 34. The worm gear mechanism here plays the role of changing the direction of rotation. The threaded sleeve 34 and the screw 13 are equivalent to a nut screw mechanism, which plays the role of converting rotation into linear motion. Both have a self-locking effect, which can ensure that the box door 1 is reliably closed. Of course, in other embodiments, a bevel gear transmission mechanism can also be used to change the direction of rotation, and a rack and pinion mechanism can also be used to convert rotation into linear motion.

[0038] In order to facilitate the orderly winding of the external wire, in other preferred embodiments, the distribution box is also equipped with an auxiliary winding mechanism located below the cable winding roller 55, such as Figure 15-17 As shown, the auxiliary winding mechanism includes a rotatable first auxiliary roller 61 and a second auxiliary roller 62. Specifically, the first auxiliary roller 61 and the second auxiliary roller 62 can be arranged at intervals through the functional frame 6, and the space between the two is for the external wire to pass through. The cable winding roller 55 rotates synchronously when winding the cable, and the first auxiliary roller 61 and the second auxiliary roller 62 rotate synchronously. It should be noted that the synchronous rotation here includes two types: passive rotation and active rotation. The so-called passive rotation means that when the external wire moves upward when being wound, the external wire is in frictional contact with the first auxiliary roller 61 and the second auxiliary roller 62, so that the first auxiliary roller 61 and the second auxiliary roller 62 rotate synchronously. The so-called active rotation means that when the external wire moves upward when being wound, one of the first auxiliary roller 61 and the second auxiliary roller 62 can actively rotate, specifically, Figure 15-17 For example, in this embodiment, the second auxiliary roller 62 is connected to the cable winding roller 55 in a transmission manner. Specifically, the cable winding roller 55 is connected to a fourth gear 64 for preventing rotation, and the second auxiliary roller 62 is connected to a third gear 63 for preventing rotation. The meshing transmission of the third gear 63 and the fourth gear 64 can make the second auxiliary roller 62 rotate synchronously to play the role of "active wire feeding".

[0039] As a preferred embodiment for facilitating the connection between the first bracket 3 and the second bracket 4, as Figure 1 , Figure 5 and Figure 7 As shown, fixing parts are provided at the four corners of the first bracket 3, and an internal thread structure is provided on the fixing parts (threaded holes can be drilled in the fixing parts or nuts can be embedded in the fixing parts), and a rotatable connecting screw 411 is installed at the corresponding position of the second bracket 4. The second bracket 4 and the first bracket 3 can be connected and locked by connecting and cooperating with the connecting screw 411 and the internal thread structure.

[0040] Furthermore, if Figure 8As shown, in order to facilitate the screwing of the connecting screws 411, a sprocket 412 is installed on each connecting screw 411, and the same ring chain 413 passes around the sprockets 412 of each connecting screw 411 to drive each connecting screw 411 to rotate synchronously. At this time, the four connecting screws 411 can be directly rotated, which is convenient and efficient. Of course, in other embodiments, the sprocket 412 can also be equivalently replaced by a pulley, and the chain 413 can be equivalently replaced by a synchronous belt.

[0041] In order to facilitate the screwing of the connecting screw 411 in the initial stage of the engagement between the connecting screw 411 and the internal thread structure, a hand crank can be connected to the eccentric position of the head of the screw 13 of one of the connecting screws 411 .

[0042] Of course, in other embodiments, the method of connecting the first bracket 3 and the second bracket 4 with a flange bolt connection structure is not excluded.

[0043] In order to make the distribution box more stable when it is lifted up and down along the pole, in addition to the main climbing roller that can "actively" rotate, the first bracket 3 and the second bracket 4 are also provided with auxiliary climbing rollers. Specifically, the auxiliary climbing roller on the first bracket 3 can be defined as the first auxiliary climbing roller 36, and the auxiliary climbing roller on the second bracket 4 can be defined as the second auxiliary climbing roller 44. Figure 5 and Figure 7 Shown, auxiliary climbing roller can be provided with two or even more.Under the situation that space is limited, auxiliary climbing roller can only be provided with one.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
