Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer with a lead-out mechanism. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change voltage. It consists of an iron core, a primary coil, and a secondary coil, and is widely used in power transmission, distribution systems, and various electrical equipment. By changing the turns ratio of the coils, a transformer can achieve voltage conversion, ensuring minimal power loss during long-distance transmission and adjusting the voltage level as needed.

[0003] Chinese patent publication number CN218100923U discloses a transformer with a lead wire protection mechanism, relating to the field of transformers. The transformer includes a casing, a top plate fixedly connected to the top of the casing, and three low-voltage and high-voltage lead wire terminals protruding from the surface of the top plate. A protective sleeve is fitted around the low-voltage lead wire terminals, and connecting plates are fixedly connected to the outer walls of both sides of the protective sleeve. The connecting plates are fixed to the surface of the top plate through screw holes and screw threads. A cover is hinged to the top of the protective sleeve. Three through holes are provided on the front outer wall of the protective sleeve corresponding to the positions of the low-voltage lead wire terminals. Lead wires are installed at the top of each of the three low-voltage lead wire terminals, with the other end of the lead wire passing through the through hole. A plug is installed between the lead wire and the through hole. By setting a protective sleeve and cover on the top of the transformer, the connection between the low-voltage lead wire terminals and the lead wires is sealed and protected internally, preventing external moisture from entering and corroding the lead wires and low-voltage lead wire terminals during rain, thus providing better protection.

[0004] However, the current transformer has the following problems: during the installation of multiple sets of lead wires, the lead wires are easily dragged by workers. Dragging the lead wires can easily lead to loosening or detachment of the wiring, affecting the normal operation of the transformer, reducing the power transmission efficiency, or causing interference between circuits, thus affecting the overall operation of the system. Therefore, we propose a transformer with a lead wire mechanism. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a transformer with a lead-out mechanism, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A transformer with a lead-out mechanism, comprising a transformer body, wherein a plurality of high-voltage lead-out terminals are fixed on one side of the top of the transformer body, and a plurality of low-voltage lead-out terminals are fixed on the other side of the top of the transformer body; a protective shell is fixed on the top of the transformer body, and a plurality of vertical plates are fixed on the top of the transformer body; an opening for accommodating the vertical plates is provided on one side of the protective shell, and a through hole for accommodating lead wires is provided above the opening of the protective shell; a rain shield is fixed on the top of the protective shell; and a plurality of [unclear text - possibly related to a specific type of protective shell or structure] are provided on the side of the protective shell away from the high-voltage lead-out terminals. An anti-drag device is provided, comprising two sliding rods that are laterally connected and slidably mounted on the side of the protective shell away from the high-voltage output end. A spring is provided between the sliding rod and the inner wall of the protective shell. A screw is threadedly connected to the side of each sliding rod away from the protective shell. An arc clamp is rotatably mounted on the side of each screw that is close to each other. A limit rod is fixed to the side of the arc clamp near the sliding rod, and the limit rod is laterally slidably mounted on the outside of the sliding rod. When the screw is rotated, the position of the arc clamp is restricted by the limit rod, so the screw will push the arc clamp towards the guide line, thereby clamping and fixing the guide line.

[0007] According to the above technical solution, the anti-drag device further includes a connecting plate, a triangular block plate, and two elastic telescopic columns. The connecting plate is fixed to the top of the two sliding rods near the high-voltage outlet end. The fixed ends of the two elastic telescopic columns are both fixed to the top of the inner wall of the protective shell. The triangular block plate is fixed to the bottom of the telescopic ends of the two elastic telescopic columns. Several triangular blocks are fixed to the bottom of the triangular block plate, and triangular blocks are fixed to the top of the connecting plate. The inclined surfaces of the triangular blocks are opposite to the inclined surfaces of the triangular blocks. Simultaneously, after the guide line is fixed to the arc clamp plate, the sliding rod is pushed towards the protective shell, and the sliding rod drives the connecting plate to move accordingly. When the connecting plate... The inclined surface of the second triangular block pushes the inclined surface of the first triangular block of the triangular block plate, causing the triangular block plate to move upward. The triangular block plate also squeezes the elastic telescopic column. When the sliding rod stops being pushed, under the elastic force of the elastic telescopic column, the telescopic end of the elastic telescopic column pushes the triangular block plate downward. At this time, the vertical surface of the second triangular block of the connecting plate abuts against the vertical surface of the first triangular block of the triangular block plate, thereby restricting the position of the connecting plate and the position of the sliding rod. During this process, the arc clamping plate moves part of the guide line towards the protective shell, causing the guide line between the arc clamping plate and the protective shell to bend. The bent part of the guide line is the reserved guide line.

[0008] According to the above technical solution, an anti-wear device is provided on the side of the slide rod away from the protective shell. The anti-wear device includes a semi-arc frame, which is fixed on the side of the two slide rods away from the protective shell. Two arc-shaped sliding plates are slidably installed inside the semi-arc frame, and the two arc-shaped sliding plates are staggered. An arc-shaped plate is fixedly installed on the top of each of the two arc-shaped sliding plates by a spring. The arc-shaped plate is made of rubber, and its inner side is smooth. A fixing post is fixed on the side of each of the two arc-shaped sliding plates away from the slide rod. Two L-shaped rods are slidably installed on the side of the semi-arc frame away from the slide rod. A through-groove plate is fixed to the bottom of the L-shaped rod. A through-groove is formed on the outer wall of the through-groove plate on the side away from the L-shaped rod. The fixing post is slidably installed in the through-groove plate. The L-shaped rod has a hinged connecting rod at one end near the slide rod, and a slider at the other end away from the L-shaped rod. The slider is slidably mounted on the top of the slide rod, and a spring is provided between the slider and the slide rod. The slider protrudes two centimeters from the top of the slide rod. When the slide rod moves toward the protective shell, the slide rod will drive the slider to continue moving until the slider abuts against the outer wall of the protective shell. As the slide rod continues to move, the slider will push the hinged connecting rod to drive the L-shaped rod to move upward along the outside of the semi-arc frame. The L-shaped rod drives the through-slot plate to move upward, the through-slot plate drives the fixed column to move upward, and the fixed column drives the arc-shaped sliding plate to rotate upward along the inner wall of the semi-arc frame. The arc-shaped sliding plate drives the arc plate to rotate upward through the spring, so that the two arc plates wrap around the guide line.

[0009] According to the above technical solution, a bending device is provided on the side of the protective shell away from the high-voltage output end. The bending device includes two elastic telescopic rods. The fixed ends of the two elastic telescopic rods are slidably installed on the outside of the protective shell. A pressure roller is rotatably installed between the tops of the fixed ends of the two elastic telescopic rods. The bottom of the telescopic ends of the two elastic telescopic rods are hinged to hinge rods. The ends of the two hinge rods away from the elastic telescopic rods are respectively hinged to the bottoms of two sliding rods. When the sliding rods move towards the protective shell, the sliding rods push the hinge rods to move the elastic telescopic rods downward along the outer wall of the protective shell. The elastic telescopic rods will drive the pressure rollers to move downward. The pressure rollers press the bent part of the guide wire downward, thereby ensuring that the bent part of the guide wire bends downward each time. In rainy weather, since the bent part of the guide wire is downward, the guide wire will guide the rainwater downward.

[0010] According to the above technical solution, elastic telescopic rod 2 is fixed to the side of the fixed end of each of the two elastic telescopic rods 1 away from the protective shell, and the elastic telescopic rod 2 is arranged horizontally. Baffles are fixed to the side of the telescopic ends of the two elastic telescopic rods 2 that are close to each other. The two baffles are located on the bottom sides of the pressure roller respectively. At the same time, under the elastic force of the elastic telescopic rod 2, the telescopic end of the elastic telescopic rod 2 will drive the baffle to contact the outer walls of both sides of the guide line.

[0011] This invention provides a transformer with a lead-out mechanism. It has the following beneficial effects: (1) The present invention uses an anti-drag device to enable the screw, the arc clamp, and the limiting rod to work together to clamp and fix the guide wire, thereby firmly fixing the guide wire in the designated position and reducing the loosening or falling off of the guide wire caused by external forces (such as collisions or drags by workers during operation). This ensures the stability of the electrical connection and avoids electrical faults or poor contact. At the same time, the sliding rod, the connecting plate, the triangular block plate, and the elastic telescopic column work together to restrict the position of the sliding rod by the connecting plate, and the arc clamp drives part of the guide wire to move towards the protective shell, thereby causing the guide wire between the arc clamp and the protective shell to bend. The bent part of the guide wire is a reserved guide wire. The bent part of the guide wire can make the guide wire more flexible. When external forces are applied, the deformation of the bent part of the guide wire absorbs a certain amount of stress, reducing the direct application of external forces to the straight part of the guide wire, avoiding excessive stretching or twisting of the guide wire, and reducing the probability of line damage or loosening caused by workers dragging.

[0012] (2) The present invention, through the setting of the anti-wear device, enables the sliding rod, protective shell, slider, hinge rod, L-shaped rod, semi-arc frame, through slot plate, fixed column and arc-shaped sliding plate to drive the arc plate to rotate upward, so that the two arc plates wrap around the guide line. When the guide line is subjected to external force and shakes, the arc plate will buffer the external force through the compression or extension action of the spring. This buffering effect can reduce the amplitude of the guide line shaking, thereby effectively reducing the damage caused by the friction between the guide line and the arc clamp plate when the guide line shakes, and thus extending the service life of the guide line.

[0013] (3) The present invention, through the setting of the bending device, enables the sliding rod, protective shell, hinge rod II, and elastic telescopic rod I to work together to drive the pressure roller to move downward. The pressure roller presses the bent part of the guide line to move downward, thereby ensuring that the bent part of the guide line is downward each time it bends. In rainy weather, since the bent part of the guide line is downward, the guide line will guide the rainwater downward, thereby effectively preventing the rainwater from flowing along the guide line to the low voltage output end and the connection end of the guide line, avoiding the problem of the low voltage output end and the connection end of the guide line being wetted by rainwater, causing a safety hazard. At the same time, under the elastic force of elastic telescopic rod II, the telescopic end of elastic telescopic rod II will drive the baffle to contact the outer walls of both sides of the guide line. The contact between the baffle and the guide line can maintain the correct position of the guide line in the pressure roller, preventing the guide line from deviating from the working range of the pressure roller during the movement, and avoiding detachment from the pressure roller.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Please see Figure 1 - Figure 9One embodiment of the present invention is as follows: A transformer with a lead-out mechanism includes a transformer body 1. A plurality of high-voltage lead-out terminals 2 are fixed to one side of the top of the transformer body 1, and a plurality of low-voltage lead-out terminals 3 are fixed to the other side of the top of the transformer body 1. A protective shell 4 is fixed to the top of the transformer body 1, and a plurality of vertical plates 6 are fixed to the top of the transformer body 1. An opening for accommodating the vertical plates 6 is provided on one side of the protective shell 4, and a through hole for accommodating lead wires is provided above the opening of the protective shell 4. A rain shield 5 is fixed to the top of the protective shell 4. A plurality of anti-drag devices 7 are provided on the side of the protective shell 4 away from the high-voltage lead-out terminals 2. Each anti-drag device 7 includes two sliding rods 71, which are transversely penetrating and slidably mounted on the protective shell. 4. A spring is provided between the slide rod 71 and the inner wall of the protective shell 4 on the side away from the high voltage outlet 2. Both slide rods 71 ​​are threaded with screws 75 on the side away from the protective shell 4. Arc clamps 77 are rotatably installed on the side of the two screws 75 that are close to each other. A limit rod 76 is fixed on the side of the arc clamp 77 that is close to the slide rod 71. The limit rod 76 is slidably installed on the outside of the slide rod 71. Through the above structure, the arc clamp 77 clamps and fixes the guide wire, so that the guide wire can be firmly fixed in the designated position, reducing the loosening or falling off of the guide wire caused by external forces such as collisions or drags during operation. This can ensure the stability of the electrical connection and avoid electrical faults or poor contact problems.

[0018] The anti-drag device 7 also includes a connecting plate 72, a triangular block plate 73, and two elastic telescopic columns 74. The connecting plate 72 is fixed to the top of the two sliding rods 71 ​​near the high-voltage output end 2. The fixed ends of the two elastic telescopic columns 74 are fixed to the top of the inner wall of the protective shell 4. The triangular block plate 73 is fixed to the bottom of the telescopic ends of the two elastic telescopic columns 74. Several triangular blocks are fixed to the bottom of the triangular block plate 73, and triangular blocks are fixed to the top of the connecting plate 72. The inclined surfaces of the triangular blocks 72 and the inclined surfaces of the triangular blocks 73 are opposite to those of the triangular blocks 73. Through the above structure, the triangular block plate 73 is positioned opposite to the connecting plate 72. The position of plate 72 is restricted, and the position of sliding rod 71 is restricted by connecting plate 72. During this process, arc clamp plate 77 drives part of the guide line to move towards protective shell 4, thereby causing the guide line between arc clamp plate 77 and protective shell 4 to bend. The bent part of the guide line is a reserved guide line. The bent part of the guide line can make the guide line more flexible. When external force is applied, the deformation of the bent part of the guide line can absorb a certain amount of stress, reduce the direct application of external force to the straight part of the guide line, avoid excessive stretching or twisting of the guide line, and reduce the probability of line damage or loosening caused by workers dragging.

[0019] A wear-resistant device 8 is provided on the side of the slide rod 71 away from the protective shell 4. The wear-resistant device 8 includes a semi-arc frame 81, which is fixed to the side of the two slide rods 71 ​​away from the protective shell 4. Two arc-shaped slide plates 82 are slidably installed inside the semi-arc frame 81, and the two arc-shaped slide plates 82 are staggered. An arc-shaped plate 83 is fixedly installed on the top of each of the two arc-shaped slide plates 82 by a spring. The arc-shaped plate 83 is made of rubber, and its inner side is smooth. A fixing post 84 is fixed on the side of each of the two arc-shaped slide plates 82 away from the slide rod 71. Two L-shaped rods 86 are slidably installed on the side of the semi-arc frame 81 away from the slide rod 71. A through-groove plate 85 is fixed to the bottom of the L-shaped rods 86. A through groove is opened on the outer wall of the through-groove plate 85 on the side away from the L-shaped rods 86. The fixing post 84 is slidably installed inside the through groove of the through-groove plate 85. A hinge rod 87 is hinged to one end of the slide rod 71, and a slider 88 is hinged to the other end of the hinge rod 87 away from the L-shaped rod 86. The slider 88 is slidably mounted on the top of the slide rod 71, and a spring is provided between the slider 88 and the slide rod 71. The slider 88 protrudes two centimeters from the top of the slide rod 71. With the above structure, the fixed column 84 will drive the arc-shaped slide plate 82 to rotate upward along the inner wall of the semi-arc frame 81. The arc-shaped slide plate 82 drives the arc plate 83 to rotate upward through the spring, so that the two arc plates 83 wrap around the guide line. When the guide line is subjected to external force and shakes, the arc plate 83 will buffer the external force through the compression or extension of the spring. This buffering effect can reduce the amplitude of the guide line shaking, thereby effectively reducing the damage caused by the friction between the guide line and the arc clamp plate 77 when the guide line shakes, and thus extending the service life of the guide line.

[0020] In use, the guide wire is connected to the low-voltage output terminal 3, with the guide wire resting on the top of the vertical plate 6. The protective shell 4 is installed on the top of the transformer body 1, with the guide wire positioned in the through hole of the protective shell 4. Rotating the screw 75 causes the arc clamp 77 to be pushed towards the guide wire by the limiting rod 76, thus clamping and fixing the guide wire. This securely fixes the guide wire in the designated position, reducing the risk of loosening or detachment due to external forces (such as collisions or dragging during operation). This ensures the stability of the electrical connection and avoids electrical faults or poor contact. Simultaneously, after the guide wire is fixed to the arc clamp 77, the sliding rod 71 is pushed towards the protective shell 4. The sliding rod 71 moves the connecting plate 72, and the inclined surface of the second triangular block of the connecting plate 72 pushes the inclined surface of the first triangular block of the triangular block plate 73, causing the triangular block plate 73 to move upwards. The corner block 73 presses against the elastic telescopic column 74. When the sliding rod 71 is stopped being pushed, under the elastic force of the elastic telescopic column 74, the telescopic end of the elastic telescopic column 74 pushes the triangular block 73 downward. At this time, the vertical surface of the second triangular block of the connecting plate 72 abuts against the vertical surface of the first triangular block of the triangular block 73, thereby restricting the position of the connecting plate 72 by the triangular block 73, and restricting the position of the sliding rod 71 by the connecting plate 72. During this process, the arc clamp 77 drives part of the guide line to move towards the protective shell 4, thereby causing the guide line between the arc clamp 77 and the protective shell 4 to bend. The bent part of the guide line is a reserved guide line. The bent part of the guide line can make the guide line more flexible. When external force is applied, the deformation of the bent part of the guide line absorbs a certain amount of stress, reducing the direct application of external force to the straight part of the guide line, avoiding excessive stretching or twisting of the guide line, and reducing the probability of line damage or loosening caused by dragging by staff.

[0021] Simultaneously, the guide wire rests on the top of the two arc-shaped plates 83. As the slide rod 71 moves towards the protective shell 4, it drives the slider 88 to continue moving until the slider 88 abuts against the outer wall of the protective shell 4. As the slide rod 71 continues to move, the slider 88 pushes the hinge rod 87, causing the L-shaped rod 86 to move upward along the outside of the semi-arc frame 81. The L-shaped rod 86 drives the through slot plate 85 to move upward, and the through slot plate 85 drives the fixing post 84 to move upward. The fixing post 84 drives the arc-shaped slide plate 82 to rotate upward along the inner wall of the semi-arc frame 81. The arc-shaped slide plate 82 drives the arc plate 83 to rotate upward through the spring, so that the two arc-shaped plates 83 wrap around the guide wire. When the guide wire is subjected to external force and shakes, the arc plate 83 will buffer the external force through the compression or extension of the spring. This buffering effect can reduce the amplitude of the guide wire shaking, thereby effectively reducing the damage caused by the friction between the guide wire and the arc clamp plate 77 when the guide wire shakes, and thus extending the service life of the guide wire.

[0022] Please see Figure 1- Figure 9 Based on the above embodiments, in another embodiment of the present invention, a bending device 9 is provided on the side of the protective shell 4 away from the high voltage output terminal 2.

[0023] The bending device 9 includes two elastic telescopic rods 91. The fixed ends of the two elastic telescopic rods 91 are slidably installed on the outside of the protective shell 4. A pressure roller 92 is rotatably installed between the tops of the fixed ends of the two elastic telescopic rods 91. A hinge rod 93 is hinged to the bottom of the telescopic ends of the two elastic telescopic rods 91. The ends of the two hinge rods 93 away from the elastic telescopic rods 91 are respectively hinged to the bottoms of the two sliding rods 71. Through the above structure, the pressure roller 92 presses the bent part of the guide wire downward, thereby ensuring that the bent part of the guide wire bends downward each time. In rainy weather, since the bent part of the guide wire is downward, the guide wire will guide the rainwater downward, thereby effectively preventing rainwater from flowing along the guide wire to the low-voltage output terminal 3 and the connection terminal of the guide wire, avoiding the problem of the low-voltage output terminal 3 and the connection terminal of the guide wire being soaked by rainwater, which could cause safety hazards.

[0024] Two elastic telescopic rods 95 are fixed to the fixed ends of the two elastic telescopic rods 91 on the side away from the protective shell 4. The elastic telescopic rods 95 are arranged horizontally. Baffles 94 are fixed to the sides of the telescopic ends of the two elastic telescopic rods 95 that are close to each other. The two baffles 94 are located on the bottom sides of the pressure roller 92 respectively. Through the above structure, the contact between the baffles 94 and the guide line can maintain the correct position of the guide line in the pressure roller 92, prevent the guide line from deviating from the effective range of the pressure roller 92 during movement, and avoid detaching from the pressure roller 92.

[0025] In use, when the slide rod 71 moves towards the protective shell 4, the slide rod 71 pushes the hinge rod 93, causing the elastic telescopic rod 91 to move downwards along the outer wall of the protective shell 4. The elastic telescopic rod 91 then causes the pressure roller 92 to move downwards, pressing the bent portion of the guide wire downwards. This ensures that the bent portion of the guide wire bends downwards each time. In rainy weather, because the bent portion of the guide wire bends downwards, the guide wire will guide rainwater downwards, effectively preventing rainwater from flowing along the guide wire to the connection point between the low-voltage output terminal 3 and the guide wire, thus avoiding damage to the connection point between the low-voltage output terminal 3 and the guide wire. The issue of potential safety hazards caused by rainwater soaking is worth noting. When the elastic telescopic rod 91 bends the guide line downwards to its limit position via the pressure roller 92, and the hinge rod 93 continues to push the elastic telescopic rod 91, the telescopic end of the elastic telescopic rod 91 will be stretched. At the same time, under the elastic force of the elastic telescopic rod 95, the telescopic end of the elastic telescopic rod 95 will cause the baffle 94 to contact the outer walls on both sides of the guide line. The contact between the baffle 94 and the guide line can maintain the correct position of the guide line in the pressure roller 92, preventing the guide line from deviating from the effective range of the pressure roller 92 during movement and avoiding detachment from the pressure roller 92.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
