Description
Technical Field
[0001] This utility model relates to the field of auxiliary components for load switches on poles of ring network boxes, and specifically to a novel load switch device for poles of ring network boxes. Background Technology
[0002] Ring mainframe systems are an important component of the safe and stable operation of power grids. In particular, pole-mounted load switches are widely used in ring mainframe systems and have become the main equipment to ensure the normal operation of the ring mainframe system.
[0003] Specifically, when installing pole-mounted load switches inside ring main units, existing pole-mounted load switches are usually fixed to the back of the ring main unit by screws. However, this installation method is inconvenient to install and remove. If the pole-mounted load switch needs to be removed for maintenance later, it will be quite troublesome. At the same time, once the pole-mounted load switch is fixed by screws, its height is fixed and cannot be adjusted. This makes it impossible to adjust the height of the pole-mounted load switch according to the incoming line when it is necessary to adjust the height of the pole-mounted load switch. It is often necessary to remove it, readjust the installation position, and reinstall it. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of load switch device on a ring network box pole to solve the above problems, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The novel ring network box pole-mounted load switch device provided by this utility model includes a pole-mounted load switch body. A back support is vertically arranged in the horizontal direction at the rear of the pole-mounted load switch body. A combination connection component with height adjustment function is combined and arranged on both sides of the bottom surface of the back support. The rear of the combination connection component is fixedly connected to the back of the inside of the ring network box.
[0007] Safety anti-sway components are assembled on both sides of the top surface of the back support, and the rear of the safety anti-sway components is fixedly connected to the back of the ring main body, so as to prevent the pole-mounted load switch body from shaking during use.
[0008] Preferably, each of the combined connecting components includes a mating plate and a fixing sleeve. The mating plates are vertically fixed on both sides of the bottom surface of the back support, and the front of each mating plate has multiple limiting holes along the longitudinal direction. The multiple limiting holes on the same side are located in the same vertical direction. The fixing sleeves are vertically arranged below both sides of the bottom surface of the back support, and the back of each fixing sleeve is fixedly connected to the back of the ring network box via a second fixing plate. The top surface of each fixing sleeve has a vertically formed mating groove, which is a through groove in the vertical direction. The mating plates slide through the corresponding mating grooves in a vertical sliding fit. The front of each fixing sleeve has a longitudinally formed mounting hole, and the mounting hole is longitudinally coaxial with one of the limiting holes on the same side. Limiting rods are inserted into the mounting holes along the longitudinal direction, and the rear ends of the limiting rods are coaxially engaged with the corresponding limiting holes.
[0009] Preferably, each of the limiting rods has a handle coaxially fixed to its front end.
[0010] Preferably, both the mounting hole and the limiting hole are threaded holes, and the limiting rods are coaxially engaged with the corresponding mounting hole and the limiting hole through threaded connection.
[0011] Preferably, both the mounting hole and the limiting hole are circular holes, and the limiting rods are coaxially engaged with the corresponding limiting holes and mounting holes through a sliding fit.
[0012] Preferably, the portion of the limiting rod between the front of the corresponding handle and the front of the fixing sleeve is coaxially fitted with a spring, and the two ends of the spring are respectively fixedly connected to the front of the corresponding handle and the front of the fixing sleeve.
[0013] Preferably, the plurality of limiting holes on the same side are evenly distributed in the vertical direction, and the horizontal cross-sectional shape of the mating plate and the mating groove are both rectangular.
[0014] Preferably, each of the safety anti-movement components includes a vertical pole and a U-shaped bracket. The vertical pole is vertically fixed on both sides of the top surface of the back support, and the U-shaped bracket is suspended above both sides of the top surface of the back support. The back of each U-shaped bracket is fixed to the back of the ring network box through a fixing plate. The top, bottom, and front of each U-shaped bracket are open, and the vertical pole passes through the corresponding U-shaped bracket in a vertical sliding fit. The outer end faces of the U-shaped brackets on both sides, which are far apart from each other, are provided with mating holes in the transverse direction. All mating holes are through holes, and each mating hole is threaded with a clamping stud inserted in the transverse direction.
[0015] Preferably, the outer ends of the clamping studs on both sides, which are far apart from each other, are coaxially fixed with handwheels, and the inner ends of the clamping studs on both sides, which are close to each other, are coaxially fixed with elastic pressure blocks whose outer diameter is smaller than the diameter of the mounting hole.
[0016] Preferably, when all the limiting rods are longitudinally slidingly engaged with the limiting hole at the highest position, the distance between the bottom surface of the U-shaped card holder and the top surface of the back bracket is greater than the vertical dimension of the mating plate.
[0017] The novel pole-mounted load switch device for ring main units, specifically in the actual configuration of the pole-mounted load switch body, features a combined connecting assembly on both sides of the bottom surface of the back support of the pole-mounted load switch body. The rear of this combined connecting assembly is fixedly connected to the back of the ring main unit. The pole-mounted load switch body can be detachably fixed inside the ring main unit through a vertical sliding engagement between the mating plate and the mating groove, and a longitudinal sliding engagement between the limiting rod and the limiting hole. Simultaneously, simply pulling the limiting rod out of the limiting hole allows the mating plate to slide vertically out of the mating groove, enabling the pole-mounted load switch body to be removed from the ring main unit. The assembly and disassembly of the pole-mounted load switch body inside the ring main unit is simple and easy to implement, facilitating both quick assembly and subsequent removal for maintenance. Furthermore, the combined connecting assembly has a height adjustment function, allowing for easy assembly and disassembly through the mating plate and the limiting hole. The plate slides vertically along the mating groove and engages longitudinally with the limiting holes at different heights via the limiting rod, allowing for fine-tuning of the height of the pole-mounted load switch body. This facilitates adjustments to the operating height of the load switch body based on the actual incoming line. Since the safety anti-movement components are mounted on both sides of the top surface of the back support of the pole-mounted load switch body, and the rear of these components is fixed to the back of the ring main unit, the upright is secured to the U-shaped bracket. Tightening the clamping studs after the upright is inserted into the U-shaped bracket prevents the elastic block from pressing against the upright surface. This secures the upright and the back support, preventing the load switch body from shaking during use. Loosening the clamping studs allows the upright to slide vertically along the U-shaped bracket, preventing the safety anti-movement components from interfering with the height adjustment function of the combined connection assembly and improving the flexibility of the safety anti-movement components.
[0018] The beneficial effects are as follows: 1. The present invention has a combination connection component on both sides of the bottom surface of the back support of the pole-mounted load switch body. The rear part of the combination connection component is fixedly connected to the back of the ring network box. Then, by means of vertical sliding fit between the mating plate and the mating groove and longitudinal sliding fit between the limiting rod and the limiting hole, the pole-mounted load switch body can be detachably assembled and fixed inside the ring network box. At the same time, only by pulling the limiting rod out of the limiting hole can the mating plate slide vertically out of the mating groove, so that the pole-mounted load switch body can be removed from the ring network box. The assembly and disassembly of the pole-mounted load switch body inside the ring network box is simple and easy to realize. It is convenient to quickly assemble the pole-mounted load switch body inside the ring network box for use, and it is also convenient to remove the pole-mounted load switch body from the ring network box for maintenance.
[0019] 2. The combined connection assembly has a height adjustment function. By sliding the mating plate vertically along the mating groove and longitudinally engaging with the limiting holes at different heights through the limiting rod, the position height of the pole-mounted load switch body can be finely adjusted, which is convenient to adapt the usage position height of the pole-mounted load switch body according to the actual incoming line.
[0020] 3. Safety anti-movement components are assembled on both sides of the top surface of the back support of the pole-mounted load switch body. At the same time, the rear of the safety anti-movement components is fixedly connected to the back of the ring main box. Then, by inserting the upright into the U-shaped bracket and tightening the clamping stud, the elastic pressure block is pressed against the surface of the upright. This can achieve the fixation and anti-movement of the upright and the back support, thereby preventing the pole-mounted load switch body from shaking during use.
[0021] 4. After loosening the clamping stud, the upright can slide vertically along the U-shaped bracket, which can prevent the setting of the safety anti-movement component from interfering with the height adjustment function of the combined connection component, thus improving the flexibility of the safety anti-movement component.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] See Figures 1-8As shown, this utility model provides a novel pole-mounted load switch device for a ring main unit, including a pole-mounted load switch body 2. A back support 201 is vertically arranged along the horizontal direction at the rear of the pole-mounted load switch body 2. A combined connecting assembly 3 with height adjustment function is assembled on both sides of the bottom surface of the back support 201. The rear of the combined connecting assembly 3 is fixedly connected to the back of the ring main unit. Specifically, each combined connecting assembly 3 includes a mating plate 305 and a fixing sleeve 302. The mating plate 305 is vertically fixed on both sides of the bottom surface of the back support 201. Multiple limiting holes 306 are longitudinally formed on the front of each mating plate 305. Simultaneously, multiple limiting holes 306 on the same side are located in the same vertical direction. Fixing sleeves 302 are vertically arranged on both sides of the bottom surface of the back support 201. The back of each fixing sleeve 302 is fixedly connected to the back of the ring network box via fixing plates 301. Each fixing sleeve 302 has a vertically formed mating groove 307 on its top surface. The mating grooves 307 are all through grooves in the vertical direction, and the mating plates 305 slide through the corresponding mating grooves 307 in a vertical sliding fit. Each sleeve 302 has a longitudinally extending mounting hole 309 on its front side, and each mounting hole 309 is longitudinally coaxially aligned with one of the limiting holes 306 on the same side. A limiting rod 308 is inserted into each mounting hole 309 longitudinally coaxially, and the rear end of each limiting rod 308 is coaxially engaged with the corresponding limiting hole 306. This arrangement allows the pole-mounted load switch body 2 to be detachably and securely fixed to the ring network through a vertical sliding engagement between the mating plate 305 and the mating groove 307, and a longitudinal sliding engagement between the limiting rod 308 and the limiting hole 306. Inside the box, the mating plate 305 can be vertically slid out of the mating groove 307 by simply pulling the limiting rod 308 out of the limiting hole 306. This allows the pole-mounted load switch body 2 to be removed from the ring network box. The assembly and disassembly of the pole-mounted load switch body 2 inside the ring network box is simple and easy to achieve. Moreover, by sliding the mating plate 305 vertically along the mating groove 307 and longitudinally engaging the limiting rod 308 with the limiting holes 306 at different heights, the position and height of the pole-mounted load switch body 2 can be finely adjusted.
[0035] See Figures 1-5As shown, safety anti-sway components 1 are assembled on both sides of the top surface of the back support 201, and the rear of the safety anti-sway components 1 is fixedly connected to the back of the ring network box. This is to prevent the pole-mounted load switch body 2 from shaking during use. Specifically, each safety anti-sway component 1 includes a vertical rod 106 and a U-shaped bracket 102. Vertical rods 106 are vertically fixed on both sides of the top surface of the back support 201, and U-shaped brackets 102 are suspended above both sides of the top surface of the back support 201. The back of each U-shaped bracket 102 is fixedly connected to the back of the ring network box via a fixing plate 101. The top, bottom, and front of the U-shaped bracket 102 are open, and the vertical rods 106 slide through the corresponding U-shaped brackets 102 in a vertical sliding manner. The U-shaped brackets on both sides... Each of the outer end faces of the 102, which are far apart from each other, has a mating hole 105 opened laterally. The mating holes 105 are all through holes, and each of the mating holes 105 has a clamping stud 103 inserted laterally in a threaded manner. The purpose of this arrangement is that, firstly, by inserting the upright 106 into the U-shaped bracket 102 and then tightening the clamping stud 103, the elastic pressure block 107 is pressed against the surface of the upright 106. This can achieve the fixation and anti-movement of the upright 106 and the back bracket 201, thereby preventing the pole-mounted load switch body 2 from shaking during use. At the same time, by simply loosening the clamping stud 103, the upright 106 can slide vertically along the U-shaped bracket 102, thereby preventing the setting of the safety anti-movement component 1 from interfering with the height adjustment function of the combined connection component 3.
[0036] See Figures 1-5 As shown, the following optimizations were made to the combined connection assembly 3 and the safety anti-movement assembly 1. Specifically, for the combined connection assembly 3, a handle 304 is coaxially fixed to the front end of each limiting rod 308, so that the limiting rod 308 can be moved by applying force by holding the handle 304. Optionally, both the mounting hole 309 and the limiting hole 306 are threaded holes, and the limiting rod 308 is coaxially engaged with the corresponding mounting hole 309 and limiting hole 306 through threaded connection, so that the limiting rod 308 and the limiting hole 306 can be quickly assembled and disassembled by screwing. Alternatively, both the mounting hole 309 and the limiting hole 306 are circular holes, and the limiting rod 308 is coaxially engaged with the corresponding limiting hole 306 and mounting hole 309 through a sliding fit. The portion of the limiting rod 308 between the corresponding handle 304 and the front of the fixing sleeve 302 is coaxially fitted with a spring 303, and the two ends of the spring 303 are fixedly connected to the front of the corresponding handle 304 and the fixing sleeve 302, respectively. This arrangement facilitates the quick separation and assembly of the limiting rod 308 and the limiting hole 306 by pulling and releasing the limiting rod 308.
[0037] See Figures 1-8As shown, multiple limiting holes 306 on the same side are evenly distributed vertically. The horizontal cross-sectional shape of the mating plate 305 and the mating groove 307 is rectangular. This arrangement facilitates a certain pattern during height adjustment and provides good guidance and correction when the mating plate 305 slides vertically along the mating groove 307. Specifically, for the safety anti-movement component 1, the outer ends of the clamping studs 103 on both sides are coaxially fixed with handwheels 104, and the inner ends of the clamping studs 103 on both sides are coaxially fixed with elastic blocks 107 whose outer diameter is smaller than that of the mounting hole 309. This arrangement facilitates the rotation of the clamping studs 103 by applying force with the handwheels 104, and also improves the locking stability of the upright 106 by directly pressing the elastic blocks 107 against the surface of the upright 106. Alternatively, when the limiting rods 308 are all longitudinally slidingly engaged with the limiting holes 306 at the highest position, the distance between the bottom surface of the U-shaped card holder 102 and the top surface of the back support 201 is greater than the vertical dimension of the mating plate 305. This arrangement ensures that there is sufficient distance between the bottom surface of the U-shaped card holder 102 and the top surface of the back support 201, allowing the mating plate 305 to smoothly slide out of the mating groove 307.
[0038] Using the above structure, specifically in the actual installation of the pole-mounted load switch body 2, since combined connecting components 3 are assembled on both sides of the bottom surface of the back support 201 of the pole-mounted load switch body 2, and the rear of the combined connecting components 3 is fixedly connected to the back of the ring main body, the pole-mounted load switch body 2 can be detachably assembled and fixed inside the ring main body through the vertical sliding engagement of the mating plate 305 and the mating groove 307 and the longitudinal sliding engagement of the limiting rod 308 and the limiting hole 306. At the same time, it is only necessary to pull the limiting rod 308 outward to remove it. After the limiting hole 306 is reached, the mating plate 305 can slide vertically out of the mating groove 307, thereby allowing the pole-mounted load switch body 2 to be removed from the ring main unit. The assembly and disassembly of the pole-mounted load switch body 2 inside the ring main unit is simple and easy to implement. It is convenient to quickly assemble the pole-mounted load switch body 2 into the ring main unit for use, and it is also convenient to remove the pole-mounted load switch body 2 from the ring main unit for maintenance. Since the assembly connection component 3 has a height adjustment function, the mating plate 305 then slides along the mating groove 307. The vertical sliding mechanism, along with the longitudinal engagement of the limiting rod 308 with the limiting holes 306 at different heights, allows for fine-tuning of the position and height of the pole-mounted load switch body 2. This facilitates adjustments to the operating position and height of the pole-mounted load switch body 2 based on the actual incoming line. Furthermore, safety anti-movement components 1 are assembled on both sides of the top surface of the back support 201 of the pole-mounted load switch body 2. The rear of the safety anti-movement components 1 is fixedly connected to the back of the ring main unit, and then the upright 106 is engaged with the U-shaped bracket 102. Tightening the clamping stud 103 after the interval allows the elastic block 107 to press against the surface of the upright 106, thus fixing the upright 106 and the back support 201 to prevent movement. This prevents the pole-mounted load switch body 2 from shaking during use. Loosening the clamping stud 103 allows the upright 106 to slide vertically along the U-shaped bracket 102, preventing the safety anti-movement component 1 from interfering with the height adjustment function of the combined connection component 3, thereby improving the flexibility of the safety anti-movement component 1.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
