Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a distribution network frame used for active distribution network engineering. Background Art

[0002] Power engineering is engineering related to the production, transmission and distribution of electric energy. In the traditional energy system, the power system realizes power supply through power generation, transformation, transmission and distribution, and is a network that distributes electric energy in one direction. Because it receives electric energy from the main grid and distributes electric energy to users at the same time, power often flows in one direction, so we call it a "passive distribution network". However, as more and more distributed power sources are connected to the large power grid, the single distribution network form and power flow direction have changed from "passive unidirectional" to "active bidirectional". Therefore, the distribution network also has a new name - "active distribution network", also known as "active distribution network".

[0003] The biggest difference between active distribution network and passive distribution network lies in the "source". The "source" mainly refers to distributed power sources, generally including distributed photovoltaic, small hydropower, decentralized wind power, small gas turbines, energy storage, electric vehicles, etc. When the active distribution network transmits electricity and adds lines, it is necessary to set up distribution racks along the way to support and fix the wires, usually poles, that is, to fix the wire racks on the poles to support and limit the wires. However, when laying wires, the distribution racks can only lay wires in a single direction, and the direction cannot be changed after the distribution racks are fixed. For wires in multiple directions, multiple distribution racks need to be installed, which increases planning costs and consumes manpower and material resources. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a distribution network frame for active distribution network engineering.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a distribution network rack for active distribution network projects, comprising a mounting member and two fixed poles fixedly connected to the upper surface of the mounting member, the top of the outer surface of the fixed pole is sleeved and fixedly connected with a support ring, the upper surface of the support ring is rotatably connected with a mounting ring, the side wall of the mounting ring is threaded with multiple bolts, and the outer surface of the mounting ring is sleeved and fixedly connected with a connecting plate, the outer surfaces of the connecting plates are hinged with support plates at both ends, and the upper surfaces of the two support plates are installed with cable fixing mechanisms.

[0006] Furthermore, one end of the support plate close to the lower surface of the connecting plate is rotatably connected to a rotating shaft, and the outer surface of the rotating shaft is sleeved and fixedly connected to a fixing plate, and one end of the fixing plate abuts against the lower surface of the connecting plate.

[0007] Furthermore, the cable fixing mechanism includes a fixed block fixedly connected to the upper surface of the support plate and a movable block slidably connected to the upper surface of the support plate. The tops of the fixed block and the movable block are hinged with connecting rods, and one end of the two connecting rods is jointly hinged with a positioning plate.

[0008] Furthermore, the cable fixing mechanism also includes a plurality of clamping plates fixedly connected to the upper surface of the positioning plate, each of the plurality of clamping plates is provided with a corresponding other clamping plate above, a screw rod is threadedly connected through the side wall of a single clamping plate at the bottom in each group, and one end of the screw rod in each group extends through and extends to the top of the corresponding other clamping plate;

[0009] A spring is symmetrically fixedly connected between the two corresponding clamping plates in each group, and the spring is sleeved on the outside of the screw rod.

[0010] Furthermore, a slide bar is fixedly connected to the bottom of the front side of the outer surface of the movable block, a locking pin is threadedly connected to the bottom side wall of the slide bar, a clamping plate is fixedly connected to the end of the locking pin, and the upper surface of the clamping plate is in contact with the lower surface of the support plate.

[0011] Furthermore, a sliding groove matching the movable block is provided on the upper surface of the support plate.

[0012] Furthermore, a mounting plate is fixedly connected to the bottoms of the two fixed poles, and a transformer is fixedly mounted on the upper surface of the mounting plate.

[0013] Beneficial effects of the utility model:

[0014] 1. When the utility model is in use, the support ring, mounting ring, connecting plate, support plate and fixing plate are arranged, and the direction of the support plate relative to the support ring can be changed by rotating the mounting ring, that is, the direction of the support plate and the cable fixing mechanism above it can be changed according to the actual power distribution plan, so that after the fixed pole is installed on the ground, the wires in different directions can still be freely installed, which reduces the trial and error cost when the fixed pole is not installed in place, thereby reducing the power distribution planning cost;

[0015] 2. When the utility model is in use, the cable fixing mechanism is set up, and the position of the movable block relative to the fixed block can be changed by using the slide bar and the locking pin, thereby changing the vertical height of the positioning plate and the clamping plate, so that the heights of the wires installed on the tops of two adjacent fixed poles on the same distribution rack are different, so that the same distribution grid can fix multiple wires in different directions, ensuring that the wires in all directions remain parallel to each other and do not contact each other, reducing interference, entanglement and even conduction between the two.

DETAILED DESCRIPTION

[0024] like Figure 1 - Figure 6 As shown, it relates to a distribution network rack for active distribution network engineering, including a mounting member 2 and two fixed poles 1 fixedly connected to the upper surface of the mounting member 2, wherein the bottoms of the two fixed poles 1 are commonly fixedly connected with a mounting plate 3, and a transformer 4 is fixedly installed on the upper surface of the mounting plate 3. The active distribution network is composed of overhead lines, cables, supporting parts, distribution transformers, disconnectors, reactive power compensators and some auxiliary facilities. In order to be concise and easy to read, only the relevant transformer 4 is shown in the technical solution of this application;

[0025] A support ring 5 is sleeved and fixedly connected to the top of the outer surface of the fixed wire rod 1, and a mounting ring 6 is rotatably connected to the upper surface of the support ring 5. A plurality of bolts 7 are threadedly connected to the side wall of the mounting ring 6. By tightening the bolts 7 and screwing them into the top side wall of the support ring 5, the rotation position of the mounting ring 6 can be locked relative to the support ring 5 and the fixed wire rod 1. A connecting plate 8 is sleeved and fixedly connected to the outer surface of the mounting ring 6. When the rotation angle of the mounting ring 6 relative to the fixed wire rod 1 is fixed, the positions of the connecting plate 8 and the supporting plate 9 are also locked, so that the orientation of the supporting plate 9 relative to the horizontal plane where the fixed wire rod 1 is located can be changed by changing the angle of the mounting ring 6.

[0026] Both ends of the outer surface of the connecting plate 8 are hinged with support plates 9 (the bottom of the connecting plate 8 is hinged with the support plate 9 by means of hinges, so that the support plate 9 can rotate up and down at a large angle around the bottom of the connecting plate 8), and the upper surfaces of the two support plates 9 are installed with cable fixing mechanisms, that is, the support plates 9 can rotate up and down vertically around the position of the bottom of the connecting plate 8, so that the state of the support plates 9 can be changed, so that it is in a horizontal state that forms a straight line with the connecting plate 8 or in an inclined state that has an angle with the connecting plate 8, among which only the final horizontal state is the target angle for installing the erection wire;

[0027] like Figure 5 As shown, the support plate 9 is rotatably connected to one end of the lower surface of the connecting plate 8 by a rotating shaft 11, and a fixing plate 10 is sleeved and fixedly connected to the outer surface of the rotating shaft 11, and one end of the fixing plate 10 abuts against the lower surface of the connecting plate 8. Through the existence of the rotating shaft 11, the fixing plate 10 and the support plate 9 form a rotatable connection relationship in the horizontal plane, that is, the fixing plate 10 can rotate around the support plate 9 in the horizontal direction with the rotating shaft 11 as the center. When the fixing plate 10 is in a position abutting against the lower surface of the connecting plate 8, the support plate 9 and the connecting plate 8 form a horizontally placed state, and the support plate 9 can no longer continue to rotate around the connecting plate 8. When the fixing plate 10 rotates to the point where it does not abut against the lower surface of the connecting plate 8, the support plate 9 can rotate around the bottom of the connecting plate 8.

[0028] Among them, by setting the smoothness of the rotating shaft 11 (or the rotation force, in layman's terms, it is actually a change in the force of the rotating shaft when it rotates), it can be ensured that the fixed plate 10 can be fixed when it is rotated to a certain angle, which is similar to the damping rotating shaft used in laptop computers in the prior art, or the rotating shaft of the two movable riveted points of the blades on the scissors. By controlling the rotation smoothness of the rotating shaft, the scissors can be controlled to remain fixed at a certain angle.

[0029] The cable fixing mechanism includes a fixed block 16 fixedly connected to the upper surface of the support plate 9 and a movable block 15 slidably connected to the upper surface of the support plate 9, wherein a slide groove 17 matching the movable block 15 is provided on the upper surface of the support plate 9, and a connecting rod 18 is hinged on the top of the fixed block 16 and the movable block 15, and a positioning plate 19 is hinged at one end of the two connecting rods 18. By moving the movable block 15 along the slide groove 17, when the distance between the movable block 15 and the fixed block 16 changes, the angle formed between the connecting rods 18 connected to them will change, thereby realizing the change of the vertical height of the positioning plate 19;

[0030] The bottom of the front side of the outer surface of the movable block 15 is fixedly connected with a slide bar 12, and the bottom side wall of the slide bar 12 is threadedly connected with a locking pin 13, and the end of the locking pin 13 is fixedly connected with a clamping plate 14, and the upper surface of the clamping plate 14 abuts against the lower surface of the support plate 9. The position of the movable block 15 can be changed by the action of the slide bar 12 and the locking pin 13. Specifically, the upper surface of the clamping plate 14 is fixedly connected with a rubber pad, which can increase the friction between the clamping plate 14 and the support plate 9. When the locking pin 13 is twisted to make the clamping plate 14 at its end tightly abut against the lower surface of the support plate 9, the presence of the rubber pad makes it more difficult for the two to slip.

[0031] The cable fixing mechanism also includes a plurality of clamping plates 20 fixedly connected to the upper surface of the positioning plate 19, and a corresponding other clamping plate 20 is arranged above each of the plurality of clamping plates 20. The side wall of the single clamping plate 20 at the bottom in each group is threadedly connected with a screw rod 21, and one end of the screw rod 21 in each group extends to the top of the corresponding other clamping plate 20. The screw rod 21 is not in contact with the side wall of the clamping plate 20 above or is rotationally connected, and the lower surface of the circular structure at the top of the screw rod 21 is in contact with the clamping plate 20 above.

[0032] A spring 22 is symmetrically fixedly connected between the two corresponding upper and lower clamping plates 20 of each group, and the spring 22 is sleeved on the outside of the screw 21. The spring 22 plays a certain supporting role, and its own elastic deformation limit limits the distance adjustment range between the two clamping plates 20;

[0033] Under the action of the screw 21, by twisting the screw 21, as the thread between the screw 21 and the side wall of the single clamping plate 20 at the bottom becomes deeper, the screw 21 will move downward, and at the same time drive the clamping plate 20 at the top to move downward, thereby changing the distance between the two clamping plates 20. On the contrary, when the screw 21 is twisted in the reverse direction, under the action of the elastic force of the spring 22, the distance between the two clamping plates 20 can change in the reverse direction and be farther apart.

[0034] When the distribution network rack for active distribution network engineering is used: first, according to the actual distribution plan, the staff can, when the support plate 9 is folded on the connecting plate 8, change the direction of the support plate 9 relative to the support ring 5 by rotating the installation ring 6, and then tighten the multiple bolts 7, that is, the direction of the support plate 9 and the cable fixing mechanism above it relative to the fixed pole 1 can be changed according to the actual distribution plan, so that after the fixed pole 1 is installed on the ground, the wires in different directions can still be freely installed, which reduces the trial and error cost when the fixed pole 1 is not installed in place, thereby reducing the distribution planning cost;

[0035] Subsequently, the folded state between the support plate 9 and the connecting plate 8 can be unfolded, and the fixing plate 10 can be rotated to the lower surface of the connecting plate 8 to support it, fixing the support plate 9 in a horizontal state, and further, the position of the movable block 15 relative to the fixed block 16 can be changed by using the slide bar 12 and the locking pin 13, thereby changing the vertical height of the positioning plate 19 and the clamping plate 20, so that the heights of the wires installed on the tops of two adjacent fixed poles 1 on the same distribution rack are different, and the wires can be fixed by using two clamping plates 20 facing each other in a group, so that the same distribution grid can fix multiple wires in different directions, ensuring that the wires in all directions remain parallel to each other and do not touch each other, thereby reducing interference, entanglement and even conduction between the two.
