Description

Technical Field

[0001] This utility model relates to the field of power transmission equipment technology, specifically a high-voltage power transmission network connection structure. Background Technology

[0002] In high-voltage transmission networks, the connection structure is a key component ensuring stable power transmission. Traditional high-voltage transmission network connection structures typically employ rigid connections. This method reveals numerous shortcomings when facing complex natural environments and grid operating conditions. On the one hand, with the continuous expansion of the power grid and the increase in transmission distance, existing patented overhead transmission line connection structures, patent publication number CN218940496U, include connecting arms, with a connecting slot fixedly connected to one side of the connecting arms and an adjusting plate fixedly connected to the other side of the connecting arms. By setting an adjustable fixing structure between the adjusting plate and the connecting slot, the adjusting plate can be fixed to the connecting slot by passing the first fixing bolt through the inside of the positioning hole and the connecting hole and tightening the first fastening sleeving on the outside of the first fixing bolt. The adjusting plate is limited by the limiting piece to keep it at the same level as the connecting slot, thereby ensuring the stability of the power transmission line connection and preventing the connection from loosening due to long-term use. Furthermore, by passing the first fixing bolt through different positioning holes and connecting holes, the length of the adjusting plate inserted into the connecting slot can be adjusted to adjust the connection distance between the power transmission lines, which is convenient for construction personnel to operate.

[0003] Regarding the aforementioned technologies, the inventors believe that they suffer from the following drawbacks: existing power lines are subject to various external forces, such as wind and earthquakes. Rigid connections cannot effectively buffer these external forces, easily leading to loosening and breakage at the connection points, affecting the stability of power transmission, and even causing power outages. Therefore, we propose a high-voltage transmission network connection structure to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-voltage power transmission network connection structure that solves the problem that existing lines are susceptible to various external forces, such as wind and earthquakes. Rigid connections cannot effectively buffer these external forces, easily leading to loosening and breakage at the connection points, affecting the stability of power transmission, and even causing power outages.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-voltage transmission network connection structure, including a guide rail mechanism, wherein longitudinally arranged guide grooves are provided on both the left and right sides of the guide rail mechanism, and a moving mechanism is installed on the outside of the guide rail mechanism and the guide grooves, wherein two sets of moving wheels are installed in a linear array inside the moving mechanism;

[0006] A servo motor is installed on the left side of the moving mechanism. The output shaft of the servo motor on the right side is connected to the moving wheel. The servo motor and the moving wheel together form a moving drive structure. Two side plate assemblies are fixedly connected in a linear array on the top surface of the moving mechanism. A bracket assembly is rotatably connected to the inner side of the side plate assembly. A connecting plate is rotatably connected to the top of the bracket assembly.

[0007] Preferably, the guide rail mechanism has two through mounting holes on both the upper and lower sides.

[0008] Preferably, the two mounting holes are arranged in a straight line array on the front and rear sides inside the guide rail mechanism, and the connecting plate has two such holes.

[0009] Preferably, the top surfaces of the two connecting plates are also fixedly connected to a guide mechanism arranged horizontally, and the top of the guide mechanism is provided with a horizontal groove.

[0010] Preferably, a wire assembly is fixedly connected inside the guide frame mechanism, and a transverse groove is provided on the outer side of the guide frame mechanism, with a servo push rod fixedly connected inside the transverse groove.

[0011] Preferably, a moving component is fixedly connected to the output end of the servo push rod, and a contact rod is fixedly connected to the side of the moving component away from the guide mechanism.

[0012] Preferably, a connector is fixedly connected to the top surface of the contact rod, and a connecting collar is fixedly connected to the side of the connector away from the contact rod. The connecting collar is sleeved on the outside of the wire assembly and is electrically connected to the wire assembly.

[0013] Beneficial effects

[0014] This utility model provides a high-voltage power transmission network connection structure. Compared with the prior art, it has the following advantages:

[0015] This high-voltage transmission network connection structure facilitates the installation and fixation of the entire structure through the set mounting holes, improving installation efficiency. The conductor assembly inside the guide frame mechanism and the servo push rod on the outside enable the moving components, contact rods and other parts to be moved precisely to the designated position, achieving precise docking between the connecting collar and the conductor assembly. Compared with traditional connection methods, there is no need for complicated calibration and fixing steps, making the operation more convenient and enabling quick connection and disconnection operations, reducing construction difficulty.

[0016] This high-voltage transmission network connection structure, through the cooperation of the guide rail mechanism and the moving mechanism, allows the connection parts to move and adjust flexibly. The moving mechanism can move on the guide groove of the guide rail mechanism. When encountering external forces, it can adjust its position to mitigate the impact of external forces on the connection parts. At the same time, the movable structure composed of the side plate assembly, bracket assembly and connecting plate allows the connection structure to adapt to different transmission line layouts and installation requirements, avoiding damage to the connection parts due to external forces or installation errors, greatly enhancing the stability of the connection, and effectively reducing the risk of power outages caused by connection problems.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6This utility model provides a technical solution: a high-voltage power transmission network connection structure, including a guide rail mechanism 1, with longitudinally arranged guide grooves 101 on both the left and right sides of the guide rail mechanism 1, and a moving mechanism 2 installed on the outside of the guide rail mechanism 1 and the guide grooves 101, with two sets of moving wheels 2011 installed in a linear array inside the moving mechanism 2.

[0026] A servo motor 201 is installed on the left side of the moving mechanism 2. The output shaft of the servo motor 201 on the right side is connected to the moving wheel 2011. The servo motor 201 and the moving wheel 2011 together form a moving drive structure. Two side plate assemblies 2012 are fixedly connected in a straight array on the top surface of the moving mechanism 2. A bracket assembly 2013 is rotatably connected to the inner side of the side plate assembly 2012. A connecting plate 2014 is rotatably connected to the top of the bracket assembly 2013.

[0027] The guide rail mechanism 1, through guide grooves 101 on both sides, cooperates with the moving mechanism 2 and its internal moving wheels 2011 to achieve movement of the moving mechanism 2 on the guide rail mechanism 1. The servo motor 201 drives the moving wheels 2011, providing power for the movement. The side plate assembly 2012, the bracket assembly 2013, and the connecting plate 2014 cooperate with each other to give the connection structure a certain degree of mobility and adjustability, providing basic support and adjustability for the installation and connection of subsequent components.

[0028] See Figures 1-2 The guide rail mechanism 1 has two through mounting holes 1011 on both the upper and lower sides.

[0029] The two bidirectional mounting holes 1011 inside the guide rail mechanism 1 facilitate the installation and fixation of the entire connection structure on other equipment or structures, ensuring the stability of the connection structure during use and making the connection between the connection structure and external equipment more secure and reliable.

[0030] See Figures 5-6 Two mounting holes 1011 are arranged in a straight line array on the front and rear sides inside the guide rail mechanism 1, and the connecting plate 2014 has two holes in total.

[0031] The mounting holes 1011 are arranged in a linear array on the front and rear sides inside the guide rail mechanism 1, and the connecting plate 2014 is set in two places. This layout enhances the stability and balance of the connection structure when connected to external equipment, ensuring that the connection structure can work stably under different working conditions and reducing structural deformation or damage caused by improper installation.

[0032] See Figures 1-2 The top surfaces of the two connecting plates 2014 are also fixedly connected with transversely arranged guide mechanism 3, and the top of the guide mechanism 3 is provided with a transverse groove.

[0033] The horizontal guide frame mechanism 3 is connected to the top of the two connecting plates 2014. The horizontal groove at the top of the guide frame mechanism 3 provides the installation position and movement track for the components to be installed later, which helps to realize the movement and positioning of other components on the guide frame mechanism 3, so that the connection structure can adapt to different power transmission line connection requirements.

[0034] See Figures 3-6 The guide frame mechanism 3 has a wire assembly 301 fixedly connected inside, and a transverse groove is provided on the outer side of the guide frame mechanism 3. A servo push rod 3011 is fixedly connected inside the transverse groove.

[0035] The guide wire assembly 301 inside the guide mechanism 3 serves as a guide, ensuring the accuracy of the movement of other components on the guide mechanism 3. The servo push rod 3011 in the transverse groove on the outer side of the guide mechanism 3 can provide power to the connected components, realizing the precise movement and position adjustment of the components on the guide mechanism 3.

[0036] See Figures 1-4 A moving component 3012 is fixedly connected to the output end of the servo push rod 3011, and a contact rod 3013 is fixedly connected to the side of the moving component 3012 away from the guide mechanism 3.

[0037] The servo push rod 3011 drives the moving component 3012 to move, and the moving component 3012 drives the contact rod 3013 to move, so that the contact rod 3013 can accurately reach the designated position, providing an actuator for connecting with the wire assembly 301 and subsequent power transmission operations.

[0038] See Figures 2-5 A connector 3014 is fixedly connected to the top surface of the contact rod 3013. A connecting collar 3015 is fixedly connected to the side of the connector 3014 away from the contact rod 3013. The connecting collar 3015 is sleeved on the outside of the wire assembly 301 and is electrically connected to the wire assembly 301.

[0039] The connecting rod 3013 is connected to the connecting collar 3015 via the connector 3014. The connecting collar 3015 is sleeved on the conductor assembly 301 and an electrical connection is achieved, thus completing the electrical connection between the connecting structure and the conductor assembly 301 and ensuring that power can be stably transmitted between the connecting structure and the conductor assembly 301.

[0040] Before applying this high-voltage power transmission network connection structure to actual transmission lines, the guide rail mechanism 1 is first installed securely on the corresponding power transmission equipment or tower support structure using the mounting holes 1011 that run through both the front and rear sides and the top and bottom of the guide rail mechanism 1, and using appropriate bolts, nuts or other fasteners. During the installation process, ensure that the mounting holes 1011 are precisely aligned with the corresponding mounting points on the support structure, and tighten the fasteners to prevent the guide rail mechanism 1 from shifting or shaking during use, thus providing a solid foundation for the stable operation of subsequent components.

[0041] When it is necessary to adjust the connection position or perform a connection operation, the servo motor 201 installed on the left side of the moving mechanism 2 is started. After the servo motor 201 is powered on, its right output shaft starts to rotate according to the preset speed and direction. Since the right output shaft of the servo motor 201 is connected to two sets of moving wheels 2011 installed in a linear array inside the moving mechanism 2, the rotation of the output shaft drives the moving wheels 2011 to rotate synchronously. The moving wheels 2011 are in close contact with the surface of the guide rail mechanism 1. Under the action of friction, the rotation of the moving wheels 2011 is converted into the movement of the moving mechanism 2 along the longitudinal guide grooves 101 on both sides of the guide rail mechanism 1.

[0042] The two side plate assemblies 2012, which are fixedly connected in a linear array on the top surface of the moving mechanism 2, remain relatively stable. The inner side of the side plate assembly 2012 is rotatably connected to the bracket assembly 2013. The bracket assembly 2013 can rotate relative to the side plate assembly 2012 within a certain angle range. This rotatable connection method allows the bracket assembly 2013 to adaptively adjust according to the movement of the moving mechanism 2 and the external connection requirements.

[0043] The top of the support assembly 2013 is rotatably connected to the connecting plate 2014. As the support assembly 2013 rotates, the connecting plate 2014 will also change its position and angle accordingly. This structural design allows the connecting plate 2014 to flexibly adapt to different connection positions and angle requirements when the moving mechanism 2 moves along the guide groove 101, providing basic adjustability for subsequent connection and precise adjustment with the guide frame mechanism 3.

[0044] The top of the two connecting plates 2014 is fixedly connected to the horizontally arranged guide mechanism 3. The top and outer sides of the guide mechanism 3 are provided with horizontal grooves. The wire assembly 301 fixedly connected inside plays a key guiding role. When it is necessary to further adjust the connection position, the servo push rod 3011 fixed in the horizontal groove on the outer side of the guide mechanism 3 starts to work.

[0045] When the servo push rod 3011 is powered on, its internal drive device, such as an electric lead screw, hydraulic or pneumatic drive element, is activated. According to the control signal, it pushes the output end to move forward or backward. The output end of the servo push rod 3011 is fixedly connected to the moving component 3012. Therefore, the movement of the output end causes the moving component 3012 to slide in the transverse groove outside the guide mechanism 3.

[0046] A contact rod 3013 is fixedly connected to the side of the moving component 3012 away from the guide mechanism 3. Therefore, the sliding of the moving component 3012 will cause the contact rod 3013 to move synchronously. During the movement, the wire assembly 301 inside the guide mechanism 3 precisely guides the movement trajectory of the moving component 3012, ensuring that the moving component 3012 and the contact rod 3013 can accurately move to the target position along the preset path.

[0047] A connector 3014 is fixedly connected to the top surface of the contact rod 3013. A connecting collar 3015 is fixedly connected to the side of the connector 3014 away from the contact rod 3013. When the contact rod 3013 reaches the designated position, the connecting collar 3015 fits onto the outside of the conductor assembly 301. The connecting collar 3015 is designed with a suitable conductive material and structure to achieve a good electrical connection with the conductor assembly 301, thereby completing the electrical connection between different lines or equipment in the high-voltage transmission network and ensuring that power can be stably transmitted between the connection structure and the conductor assembly 301.

[0048] External Force Coping and Operation and Maintenance: During the operation of the high-voltage transmission network, when encountering external forces such as wind and earthquakes, the cooperation of the guide rail mechanism 1 and the moving mechanism 2 plays a buffering and adjustment role. If affected by wind, the moving mechanism 2 can generate a certain displacement within the guide groove 101 according to the direction and magnitude of the wind, thereby mitigating the impact of the wind on the connection parts. At the same time, the movable structure composed of the side plate assembly 2012, the bracket assembly 2013, and the connecting plate 2014 will also undergo corresponding deformation and adjustment, absorbing some of the external force and preventing the connection parts from being damaged due to excessive instantaneous external force. During line inspection or maintenance, the moving mechanism 2 and the contact rod 3013 can be returned to their initial positions or moved to easily operable positions by controlling the servo motor 201 and the servo push rod 3011, facilitating the separation, inspection, and maintenance of the connecting collar 3015 and the conductor assembly 301 by the staff.

[0049] In summary, this device, equipped with a contact rod 3013, enables rapid connection and disconnection from external power facilities.

[0050] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
