Description

Technical Field

[0001] This invention relates to the field of power distribution network planning technology, and in particular to a high-efficiency power distribution network structure for power distribution network planning. Background Technology

[0002] As a crucial link connecting the transmission network and users in the power system, the distribution network's power supply reliability and operational stability directly affect the continuous operation of industrial production and the normal life of residents. With the advancement of new power system construction and the continuous growth of electricity load, the coverage of the distribution network is constantly expanding, placing more stringent requirements on the structural rationality, construction efficiency, and operational safety of the distribution network frame. The distribution network frame, as the core load-bearing structure of the distribution network, mainly consists of key components such as poles, support frames, and insulated terminals. Its core function is to provide stable support and safe insulation for transmission lines, ensuring that electricity can be efficiently and safely delivered to end users. In the structure of a power distribution network, insulated terminals play an indispensable and crucial role. They not only bear the weight of the wires and securely fix them, but more importantly, they provide reliable electrical insulation to effectively prevent leakage between the wires and the support frame or poles, thereby ensuring the safe operation of the power distribution network and the safety of people in the surrounding area. Currently, in the construction and installation of power distribution networks, the fixed connection between insulated terminals and wires is a core process, and its quality directly determines the operational stability and service life of the power distribution network. In existing technologies, the common method for fixing insulated terminals to wires is by binding with ropes. While this traditional method has certain advantages in terms of material costs, it reveals several unavoidable drawbacks in practical applications. First, from a construction efficiency perspective, the installation of power distribution network frames is often a high-altitude operation. Construction workers need to manually wrap and bind the wires with binding ropes at heights, a cumbersome and time-consuming process that significantly reduces the efficiency of high-altitude work and increases the labor intensity and operational risks for construction workers. Second, the binding quality is difficult to guarantee. The tightness of the binding depends entirely on the experience and responsibility of the construction workers. Different workers have different binding techniques, resulting in inconsistent binding quality. Some loosely bound sections are prone to wire loosening, posing a safety hazard to the operation of the power distribution network. More importantly, the binding ropes have poor durability. Power distribution grids are constantly exposed to the outdoor environment, enduring harsh conditions such as wind, sun, rain, and temperature fluctuations. Binding ropes, typically made of polymers like nylon and plastic, are prone to aging and embrittlement under long-term environmental stress, significantly reducing their tensile strength and stability. With prolonged use, aging binding ropes are prone to breakage, leading to failure in the connection between the wires and insulation terminals. This can cause problems like wire swaying and poor contact, and in severe cases, even short circuits and power outages, affecting not only the continuity of power supply but also increasing the maintenance costs and workload of the power distribution network. Therefore, there is an urgent need for a high-efficiency power distribution network frame with a reasonable structure, reliable fixation, and convenient installation of wires and insulation terminals. This would solve the problems of low construction efficiency, poor fixing quality, and insufficient durability of traditional binding methods, thereby improving the construction quality and operational stability of the power distribution network frame and ensuring the safe and efficient operation of the power distribution network. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency power distribution network frame for power distribution network planning. It can quickly fix wires and insulation terminals without manual binding operations. It has a reasonable structure and strong stability, which can effectively improve the construction quality and operational stability of the power distribution network frame and ensure the safe and efficient operation of the power distribution network.

[0004] The invention adopts the following technical solution: An efficient power distribution network frame for power distribution network planning includes a pole with a support frame at the top. An insulating terminal is mounted on the support frame, and an insulating column is mounted on the support frame to one side of the insulating terminal. A positioning plate is mounted on the insulating column, and a pressure block is positioned on the positioning plate opposite to a wire placement groove at the top of the insulating terminal. The positioning plate can slide vertically relative to the insulating column to complete positioning, and the pressure block covers the wire in the wire placement groove.

[0005] Preferably, the bottom of the pressure block is provided with an arc-shaped positioning groove.

[0006] Preferably, the positioning plate has a sliding hole, and the positioning plate is slidably connected to the insulating column through the sliding hole.

[0007] Preferably, a positioning rod is elastically provided inside the sliding hole. The positioning rod extends into the insulating column through an adjustment groove formed on the insulating column. A positioning part is provided inside the insulating column. In the initial state, the positioning rod is located above the positioning part. During operation, as the positioning pressure plate moves down, the positioning rod moves downward from the top of the positioning part to the positioning cavity. Under the elastic restoring force, the positioning rod moves into the positioning cavity to complete the positioning.

[0008] Preferably, the positioning part includes a positioning platform, and a support rod with a reduced diameter is provided at the bottom of the positioning platform, forming the positioning cavity between the support rod and the bottom surface of the positioning platform.

[0009] Preferably, a release platform is slidably provided on the support rod. The release platform is two symmetrically arranged frustum structures, and the larger end faces of the two frustums are in contact with each other. The diameter of the largest part of the release platform is not less than the diameter of the largest part of the positioning platform. The positioning plate can be slidably adjusted along the axial direction of the pressure block. A positioning plate is hinged to the top of the positioning plate. In the initial state, the positioning plate presses over the pressure block.

[0010] Preferably, the top of the positioning platform has an arc-shaped structure, and the end of the positioning rod that contacts the positioning platform has an arc-shaped structure.

[0011] Preferably, each of the positioning plates on both sides of the pressure block is provided with a mounting groove, and a side pressure rod is detachably provided in one of the mounting grooves. The positioning plate can slide and adjust along the axial direction of the side pressure rod. In the initial state, the positioning plate presses on the side pressure rod.

[0012] Preferably, an adjustment ring is provided on the top of the positioning plate.

[0013] Preferably, an arc-shaped side pressure groove is provided on the bottom of the side pressure rod near the insulating terminal.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting up insulating columns and sliding positioning plates on these columns, and utilizing the vertical sliding of the positioning plates and the pressing blocks to press down on the wires, the process of fixing wires to insulating terminals is greatly simplified. Construction workers only need to place the wire in the placement groove of the insulating terminal and push the positioning plate down the insulating column to the target position. The wire positioning is then completed through the cooperation of the pressing blocks and the placement groove. The entire process eliminates the need for complex winding actions, significantly shortening the operation time. Simultaneously, the simplified operation process reduces reliance on the experience of construction workers and reduces the time spent working at heights, fundamentally reducing labor intensity and safety risks such as falls and misoperation. It is particularly suitable for efficient construction scenarios of large-scale power distribution network structures.

[0015] Furthermore, the fixing mechanism of this invention can be made of high-strength insulating material of the same origin as the insulating terminals to form insulating columns, positioning plates, and pressure blocks. This type of material has excellent weather resistance, resistance to ultraviolet aging, and resistance to high and low temperatures, and can adapt to harsh environments such as outdoor wind, sun exposure, rain, and temperature fluctuations. Its service life is basically the same as that of the main structure of the power distribution network frame, which is far superior to traditional nylon or plastic binding ropes. This can completely solve the problems of weakening strength and breakage of binding ropes after long-term use, avoid major faults such as line short circuits and power outages caused by fixing failure, reduce the frequency of operation and maintenance inspections and maintenance workload of the power distribution network, and significantly improve the continuity and reliability of power supply.

Detailed Implementation

[0017] The invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 4 As shown, the invention discloses an efficient power distribution network frame for power distribution network planning, comprising a pole 1, a support frame 2 fixed to the top of the pole 1 by bolts, an insulating terminal 3 mounted on the support frame 2, an insulating column 4 mounted on one side of the support frame 2, a positioning pressure plate 5 mounted on the insulating column 4, and a pressure block 7 positioned opposite the wire placement groove 6 at the top of the insulating terminal 3. The positioning pressure plate 5 can slide vertically relative to the insulating column 4 to achieve positioning, and the pressure block 7 is placed on the wire in the wire placement groove 6 to complete the positioning and fixing of the wire. The operation is simple, and the entire process does not require complex winding actions, greatly shortening the operation time. At the same time, the simplified operation process reduces reliance on the experience of construction personnel, reduces the time spent working at heights, fundamentally reduces labor intensity and safety risks such as falls and misoperation, and improves safety performance.

[0018] Preferably, the bottom of the pressure block 7 has an arc-shaped positioning groove 8 to cooperate with the wire placement groove 6 on the insulating terminal 3 to complete the fixing operation of the wire and ensure the stability of the wire. One end of the positioning pressure plate 5 has a sliding hole, through which the positioning pressure plate 5 is slidably connected to the insulating column 4. An accommodating cavity is provided inside the sliding hole, and a positioning rod 10 is elastically positioned in the accommodating cavity by a spring 9. The positioning rod 10 extends into the insulating column 4 through an adjusting groove 11 on the insulating column 4, and a positioning part is provided inside the insulating column 4. Initially, the positioning rod 10 is located above the positioning part. During operation, as the positioning pressure plate 5 moves downward, the positioning rod 10 moves downward from the top of the positioning part to the positioning cavity. Under the elastic restoring force of the spring 9, the positioning rod 10 moves into the positioning cavity to complete the positioning. At this time, the pressure block 7 presses onto the wire, completing the fixing and clamping of the wire. In this invention, two positioning rods 10 are symmetrically arranged in each sliding hole to ensure the stability of the positioning pressure plate 5. Furthermore, as... Figure 1 As shown, when multiple insulating terminals 3 are provided on each support frame 2 on both sides of the pole 1, two insulating terminals 3 can share one insulating column 4, that is, the insulating column 4 is placed between two insulating terminals 3 to improve space utilization. When two insulating terminals 3 share one insulating column 4, two positioning plates 5 are set one above the other, and the positioning plate at the bottom is set as a Z-shaped structure so that its top is above the insulating terminal 3. For ease of understanding, the invention is described using the cuboid positioning plate 5 set on the upper end of the insulating column 4 as an example. For details, please refer to [link to relevant documentation]. Figure 3 .

[0019] Furthermore, in this invention, the positioning part includes a positioning platform 12, and a support rod 13 with a reduced diameter is provided at the bottom of the positioning platform 12. The support rod 13 is preferably coaxially arranged with the positioning platform 12, and a positioning cavity is formed between the support rod 13 and the bottom surface of the positioning platform 12. When the positioning plate 5 moves downward and the pressure block 7 presses onto the wire, the positioning rod 10 is located at the bottom of the positioning platform 12, thus completing the positioning of the positioning plate 5. Preferably, a release platform 14 is slidably provided on the support rod 13. The release platform 14 is two symmetrically arranged frustum structures, and the larger end faces of the two frustums are in contact. The diameter of the largest part of the release platform 14 is not less than the diameter of the largest part of the positioning platform 12, so that when it is necessary to release the pressure block 7 from the wire and control the positioning plate 5 to move upward and reset, the auxiliary positioning rod 10 can smoothly move above the positioning platform 12 without obstructing the reset of the positioning rod 10. Specifically, when it is necessary to control the positioning plate 5 to reset, press the positioning plate 5 in the working state to move it down continuously, so that the positioning rod 10 contacts the release table 14 and moves down along the inclined surface of the upper side wall of the release table 14 to the inclined surface of the lower part of the release table 14. At this time, the positioning rod 10 will extend outward under the reset action of the spring 9 due to the inward contraction of the lower inclined surface and abut against the lower side wall of the release table 14. As the positioning plate 5 is pulled up, the release table 14 will be moved to the positioning table 12. Since the bottom of the release table 14 is also a symmetrical inclined surface structure with the top, under the restriction of the positioning table 12, increasing the external force to pull the positioning plate 5 up can drive the positioning rod 10 to move smoothly up along the slope of the release table 14 and get off the positioning table 12, thereby releasing the pressure block 7 on the wire. The positioning plate 5 can be slidably adjusted along the axial direction of the pressure block 7 so that when the positioning plate 5 moves downward to the release platform 14, the movement of the positioning plate 5 will not be affected by the fixed setting of the pressure block 7 and the positioning plate 5. Specifically, a limiting groove 15 is provided on the outer side of the pressure block 7, and a through hole for the pressure block 7 to slide is provided on the positioning plate 5. A slider that is slidably connected to the limiting groove 15 is provided on the inner wall of the through hole. In addition, a positioning plate 16 is hinged to the top of the positioning plate 5 through a hinge shaft. In the initial state, the positioning plate 16 presses on the pressure block 7. This ensures that in the normal working state, the pressure of the positioning plate 16 on the pressure block 7 plays a role in limiting the pressure block 7 and ensuring the stability of the pressure block 7 in the working state. When it is necessary to reset the positioning plate 5, the positioning plate 16 is pushed away from the top of the positioning plate 5 to release the space corresponding to the pressure block 7. An adjustment ring 17 is provided on the top of the positioning plate 16. The adjustment ring 17 is preferably located at the end away from the hinge point. The setting of the adjustment ring 17 makes it convenient for the staff to use tools to hook the adjustment ring 17 and push the positioning plate 16 to move along the hinge point, providing convenience of operation.

[0020] Furthermore, the top of the positioning platform 12 is preferably designed with an arc-shaped structure, and the end of the positioning rod 10 that contacts the positioning platform 12 is also arc-shaped to reduce friction between the positioning rod 10 and the positioning platform 12 when the positioning rod 10 moves down along the positioning platform 12, thus achieving smooth sliding adjustment between the two. In addition, each of the positioning pressure plates 5 on both sides of the pressure block 7 is provided with a mounting groove 18, and a side pressure rod 19 is detachably installed in one of the mounting grooves 18. The positioning pressure plate 5 can slide and adjust along the axial direction of the side pressure rod 19. In the initial state, the positioning plate 16 presses on the side pressure rod 19. The side pressure rod 19 can meet the scenario where the wire needs to be fixed from the position of the insulating terminal 3 during construction. The side pressure rod 19 can be used to abut the wire placed in the lower space outside the wire placement groove 6 to fix the wire. In normal operation, the bottom of the side pressure rod 19 abuts against the top of the insulating terminal 3 on one side of the wire placement groove 6. An arc-shaped side pressure groove 20 is provided on the bottom side of the side pressure rod 19 near the insulating terminal 3, so that the side pressure groove 20 can be used to press against the wire, improve the fit with the wire, and ensure the stability of the wire positioning.

[0021] In this invention, the mounting groove 18 is rectangular to adjust the position of the side pressure rod 19 from the insulating terminal 3, thereby pressing the wire against the space between the lower part of the wire placement groove 6 and the upper part of the insulating terminal 3. Specifically, the side wall of the positioning pressure plate 5 has a fixing hole 21, which matches the shape of the mounting groove 18. A bolt 22 is installed in the fixing hole 21. A limiting groove 23 is vertically formed on the upper edge of the side pressure rod 19. One end of the bolt 22 passes through the mounting groove 18 and slides in the limiting groove 23. This not only limits the position of the side pressure rod 19, preventing it from moving left and right along the mounting groove 18, but also ensures that when the positioning pressure plate 5 moves down to release the positioning, the bolt 22 can move up and down along the limiting groove 23, avoiding obstruction to the movement of the positioning pressure plate 5.

[0022] In use, the insulating column 4 is installed on the support frame 2 on one side of the insulating terminal 3. Then, the wire is placed in the wire placement groove 6, and the positioning plate 5 is moved downwards, so that the positioning rod 10 is located under the positioning platform 12. At this time, the pressure block 7 presses down on the upper part of the wire, completing the positioning and fixing of the wire. The whole process is simple in structure and easy to operate. When the wire needs to be placed on the insulating terminal 3 on one side of the wire placement groove 6 according to the wiring layout, the side pressure rod 19 can be installed in the corresponding side mounting groove 18, and its distance from the insulating terminal 3 can be adjusted. Similarly, the positioning plate 5 is pressed down, the side pressure plate moves downwards, and the arc-shaped side pressure groove 20 presses against the outer end of the wire that is not in contact with the insulating terminal 3, thus completing the fixing of the wire. When it is necessary to release the positioning of the wire, push the positioning plate 16 away from the pressure block 7 and the side pressure plate, then move the positioning pressure plate 5 down. The positioning rod 10 will enter the lower converging slope along the outward-radiating slope of the upper part of the release platform 14. The positioning rods 10 on both sides are pushed out by the restoring force of the spring 9 and clamped on the outside of the release platform 14. At this time, pull up the positioning pressure plate 5, which will move the release platform 14 to contact the positioning platform 12. Increasing the pulling force will pull the positioning pressure plate 5 upward to reset it. In this way, the positioning of the wire can be released without the need for many auxiliary tools. The operation is simple, quick and easy, and highly practical.
