Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly to a transformer with a lead-out mechanism. Background Art

[0002] A transformer is an electrical device that realizes voltage increase and decrease through the principle of electromagnetic induction. 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, the transformer can achieve voltage conversion, ensure less power loss during long-distance power transmission, and adjust the voltage level as needed.

[0003] Chinese Patent with the patent announcement number CN218100923U discloses a transformer with a lead-out wire protection mechanism, which relates to the field of transformers and includes a transformer housing. A top plate is fixedly connected to the top of the transformer housing, and three low-voltage lead-out terminals and a high-voltage lead-out terminal protrude from the surface of the top plate. A protective sleeve is sleeved around the low-voltage lead-out terminal, and connecting plates are fixedly connected to the outer walls on both sides of the protective sleeve. The connecting plates are fixedly connected to the surface of the top plate through screw holes and screws opened on the surface. A shell cover is hinged above the protective sleeve. Three wire-passing holes are opened on the front outer wall of the protective sleeve at positions corresponding to the low-voltage lead-out terminals. Lead-out wires are installed on the tops of the three low-voltage lead-out terminals, and the other ends of the lead-out wires pass through the wire-passing holes. A sleeve plug is installed between the lead-out wires and the wire-passing holes. By providing a protective sleeve and a shell cover on the top of the transformer to cover the connection between the low-voltage lead-out terminal and the lead-out wire inside for sealed protection, it can prevent external water vapor from entering and corroding the lead-out wire and the low-voltage lead-out terminal when it rains, and the protection effect is better.

[0004] However, the current transformer has the following problems: During the installation of multiple groups of lead-out wires, the lead-out wires are easily accidentally dragged by the staff. Dragging the lead-out wires easily causes the wiring to become loose or fall off, affecting the normal operation of the transformer, resulting in a decrease in the power transmission efficiency or causing interference between circuits, and affecting the overall operation of the system. Therefore, we propose a transformer with a lead-out mechanism. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a transformer with a lead-out mechanism, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A transformer with a lead-out mechanism, including a transformer main body, on one side of the top of the transformer main body, a plurality of high-voltage outgoing terminals are fixed, on the other side of the top of the transformer main body, a plurality of low-voltage outgoing terminals are fixed, on the top of the transformer main body, a protective shell is fixed, on the top of the transformer main body, a plurality of vertical plates are fixed, on one side of the protective shell, an opening for accommodating the vertical plates is provided, above the opening of the protective shell, a through hole for accommodating the lead is provided, on the top of the protective shell, a rain shield is fixed, on one side of the protective shell away from the high-voltage outgoing terminals, a plurality of anti-dragging devices are provided, the anti-dragging device includes two sliding rods, the two sliding rods horizontally penetrate and are slidably installed on one side of the protective shell away from the high-voltage outgoing terminals, and a spring is provided between the sliding rods and the inner wall of the protective shell, on the side of the two sliding rods away from the protective shell, screws are threadedly connected, on the side of the two screws close to each other, arc-shaped clamping plates are rotatably installed, on the side of the arc-shaped clamping plate close to the sliding rod, a limiting rod is fixed, and the limiting rod is horizontally slidably installed outside the sliding rod. Rotating the screw, since the position of the arc-shaped clamping plate is restricted by the limiting rod, therefore, the screw will push the arc-shaped clamping plate towards the guiding wire, so that the arc-shaped clamping plate clamps and fixes the guiding wire.

[0007] According to the above technical solution, the anti-dragging device further includes a connecting plate, a triangular block plate, and two elastic telescopic columns. The connecting plate is fixed on the top of one side of the two sliding rods close to the high-voltage outgoing terminals. The fixed ends of the two elastic telescopic columns are fixed on the top of the inner wall of the protective shell. The triangular block plate is fixed on the bottom of the telescopic ends of the two elastic telescopic columns. A plurality of triangular blocks I are fixed on the bottom of the triangular block plate. A triangular block II is fixed on the top of the connecting plate. The inclined surface of the triangular block II of the connecting plate and the inclined surface of the triangular block I of the triangular block plate are arranged oppositely. At the same time, after the arc-shaped clamping plate fixes the guiding wire, push the sliding rod towards the protective shell. The sliding rod drives the connecting plate to move accordingly. When the inclined surface of the triangular block II of the connecting plate pushes the inclined surface of the triangular block I of the triangular block plate to drive the triangular block plate to move upward, and the triangular block plate squeezes the elastic telescopic column. When stopping pushing the sliding rod, under the elastic force of the elastic telescopic column, when the telescopic end of the elastic telescopic column pushes the triangular block plate to move downward, at this time, the vertical surface of the triangular block II of the connecting plate abuts against the vertical surface of the triangular block I of the triangular block plate, so that the triangular block plate restricts the position of the connecting plate, the connecting plate restricts the position of the sliding rod, and in this process, the arc-shaped clamping plate drives part of the guiding wire towards the protective shell, so that the guiding wire between the arc-shaped clamping plate and the protective shell is bent, and the bent part of the guiding wire is the reserved guiding wire.

[0008] According to the above technical solution, an anti-wear device is provided on the side of the sliding rod away from the protective shell. The anti-wear device includes a semi-circular frame fixed to the side of the two sliding rods away from the protective shell. Two arc-shaped sliding plates are slidably installed inside the semi-circular frame, and the two arc-shaped sliding plates are arranged staggeredly. Arc-shaped plates are fixedly installed at the tops of the two arc-shaped sliding plates through springs. The arc-shaped plates are made of rubber, and the inner sides of the arc-shaped plates are smooth surfaces. Fixed columns are fixed to the sides of the two arc-shaped sliding plates away from the sliding rod. Two L-shaped rods are slidably installed on the side of the semi-circular frame away from the sliding rod. A through-channel plate is fixed to the bottom of the L-shaped rod. A through-channel is opened on the outer wall of the through-channel plate away from the L-shaped rod. The fixed column is slidably installed inside the through-channel of the through-channel plate. One end of the L-shaped rod close to the sliding rod is hinged with a first hinge rod. The other end of the first hinge rod away from the L-shaped rod is hinged with a slider. The slider is slidably installed on the top of the sliding rod, and a spring is provided between the slider and the sliding rod. The slider protrudes 2 centimeters above the top of the sliding rod. When the sliding rod moves towards the protective shell, the sliding rod will drive the slider to continue moving until the slider abuts against the outer wall of the protective shell. When the sliding rod continues to move, the slider will push the first hinge rod to drive the L-shaped rod to move upward along the outside of the semi-circular frame. The L-shaped rod drives the through-channel plate to move upward. The through-channel plate drives the fixed column to move upward. The fixed column will drive the arc-shaped sliding plate to rotate upward along the inner wall of the semi-circular frame. The arc-shaped sliding plate drives the arc-shaped plate to rotate upward through the spring, so that the two arc-shaped plates wrap the guiding wire.

[0009] According to the above technical solution, a bending device is provided on the side of the protective shell away from the high-voltage outgoing end. The bending device includes two first elastic telescopic rods. The fixed ends of the two first elastic telescopic rods are slidably installed outside the protective shell. A pressing wheel is rotatably installed between the tops of the fixed ends of the two first elastic telescopic rods. The bottoms of the telescopic ends of the two first elastic telescopic rods are respectively hinged with second hinge rods. The other ends of the two second hinge rods away from the first elastic telescopic rods are respectively hinged to the bottoms of the two sliding rods. When the sliding rod moves towards the protective shell, the sliding rod pushes the second hinge rod to drive the first elastic telescopic rod to move downward along the outer wall of the protective shell. The first elastic telescopic rod drives the pressing wheel to move downward. The pressing wheel presses the bent part of the guiding wire to move downward, so as to ensure that the bent part of the guiding wire is downward each time it bends. In rainy days, since the bent part of the guiding wire is downward, the guiding wire will guide the rainwater downward.

[0010] According to the above technical solution, second elastic telescopic rods are fixed to the sides of the fixed ends of the two first elastic telescopic rods away from the protective shell, and the second elastic telescopic rods are arranged horizontally. Baffles are fixed to the sides of the telescopic ends of the two second elastic telescopic rods close to each other. The two baffles are respectively located on both sides of the bottom of the pressing wheel. At the same time, under the elastic force of the second elastic telescopic rod, the telescopic end of the second elastic telescopic rod will drive the baffle to contact the outer walls of both sides of the guiding wire.

[0011] The present invention provides a transformer with a lead-out mechanism, having the following beneficial effects:

[0012] (1) Through the setting of the anti-dragging device in the present invention, the screw rod, arc clamping plate, and limit rod cooperate to drive the arc clamping plate to clamp and fix the guiding wire, so that the guiding wire can be firmly fixed at a specified position, reducing the loosening or falling off of the guiding wire caused by external forces (such as collisions or dragging during operation by staff). This can ensure the stability of electrical connection and avoid electrical faults or poor contact problems. At the same time, the sliding rod, connecting plate, triangular block plate, and elastic telescopic column cooperate to drive the connecting plate to limit the position of the sliding rod, and the arc clamping plate drives part of the guiding wire towards the protective shell, so that the guiding wire between the arc clamping plate and the protective shell is bent. The bent part of the guiding wire is the reserved guiding wire. The bent part of the guiding wire can make the guiding wire more flexible. When an external force acts, a certain amount of stress is absorbed through the deformation of the bent part of the guiding wire, reducing the direct action of the external force on the straight part of the guiding wire, avoiding excessive stretching or twisting of the guiding wire, and reducing the probability of line damage or loosening caused by dragging by staff.

[0013] (2) Through the setting of the anti-wear device in the present invention, the sliding rod, protective shell, slider, hinge rod I, L-shaped rod, semi-arc frame, through groove plate, fixed column, and arc-shaped sliding plate cooperate to drive the arc-shaped plate to rotate upward, so that the two arc-shaped plates wrap the guiding wire. When the guiding wire shakes under the action of an external force, the arc-shaped plate will buffer the external force through the compression or extension action of the spring. This buffering effect can reduce the amplitude of the shaking of the guiding wire, effectively reducing the damage caused by the friction between the shaking guiding wire and the arc clamping plate, and thus prolonging the service life of the guiding wire.

[0014] (3) Through the setting of the bending device in the present invention, the sliding rod, protective shell, hinge rod II, and elastic telescopic rod I cooperate to drive the pressing wheel to move downward, and the pressing wheel presses the bent part of the guiding wire to move downward, so as to ensure that the bent part of the guiding wire is downward every time it bends. In rainy days, since the bent part of the guiding wire is downward, the guiding wire will guide the rainwater downward, effectively preventing the rainwater from flowing along the guiding wire to the low-voltage outgoing end and the connection end of the guiding wire, avoiding the low-voltage outgoing end and the connection end of the guiding wire from being soaked by rainwater and causing potential safety hazards. At the same time, under the elastic force of the elastic telescopic rod II, the telescopic end of the elastic telescopic rod II will drive the baffle to contact the outer walls on both sides of the guiding wire. The contact between the baffle and the guiding wire can keep the guiding wire in the correct position in the pressing wheel, preventing the guiding wire from deviating from the action range of the pressing wheel during movement and avoiding detachment from the pressing wheel.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Please refer to Figure 1 - Figure 9, an embodiment of the present invention is: a transformer with a lead-out mechanism, including a transformer main body 1. On one side of the top of the transformer main body 1, a plurality of high-voltage outgoing terminals 2 are fixed. On the other side of the top of the transformer main body 1, a plurality of low-voltage outgoing terminals 3 are fixed. A protective shell 4 is fixed on the top of the transformer main body 1. A plurality of vertical plates 6 are fixed on the top of the transformer main body 1. An opening for accommodating the vertical plate 6 is provided on one side of the protective shell 4. A through hole for accommodating the lead is provided above the opening of the protective shell 4. A rain shield 5 is fixed on the top of the protective shell 4. A plurality of anti-dragging devices 7 are provided on the side of the protective shell 4 away from the high-voltage outgoing terminal 2. The anti-dragging device 7 includes two sliding rods 71. The two sliding rods 71 penetrate horizontally and are slidably installed on the side of the protective shell 4 away from the high-voltage outgoing terminal 2, and a spring is provided between the sliding rod 71 and the inner wall of the protective shell 4. Screws 75 are threadedly connected to the sides of the two sliding rods 71 away from the protective shell 4. Arc-shaped clamping plates 77 are rotatably installed on the sides of the two screws 75 close to each other. A limiting rod 76 is fixed on the side of the arc-shaped clamping plate 77 close to the sliding rod 71, and the limiting rod 76 is horizontally slidably installed outside the sliding rod 71. Through the above structural arrangement, the arc-shaped clamping plate 77 clamps and fixes the guiding wire, so that the guiding wire can be firmly fixed at a specified position, reducing the loosening or falling off of the guiding wire caused by external forces such as the collision or dragging during the operation of the staff. This can ensure the stability of the electrical connection and avoid electrical faults or poor contact problems.

[0027] The anti-dragging device 7 further 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 sides of the two sliding rods 71 close to the high-voltage outgoing terminal 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. A plurality of triangular blocks one are fixed to the bottom of the triangular block plate 73. A triangular block two is fixed to the top of the connecting plate 72. The inclined surface of the triangular block two of the connecting plate 72 is arranged opposite to the inclined surface of the triangular block one of the triangular block plate 73. Through the above structural arrangement, the triangular block plate 73 restricts the position of the connecting plate 72, and the connecting plate 72 restricts the position of the sliding rod 71. And in this process, the arc-shaped clamping plate 77 drives part of the guiding wire to lean towards the protective shell 4, so that the guiding wire between the arc-shaped clamping plate 77 and the protective shell 4 is bent. The bent part of the guiding wire is the reserved guiding wire. The bent part of the guiding wire can make the guiding wire more flexible. When an external force acts, a certain amount of stress is absorbed through the deformation of the bent part of the guiding wire, reducing the direct action of the external force on the straight part of the guiding wire, avoiding excessive stretching or twisting of the guiding wire, and reducing the probability of line damage or loosening caused by the dragging of the staff.

[0028] On the side of the sliding rod 71 away from the protective housing 4, an anti-wear device 8 is provided. The anti-wear device 8 includes a semi-circular frame 81. The semi-circular frame 81 is fixed on the side of the two sliding rods 71 away from the protective housing 4. Two arc-shaped sliding plates 82 are slidably installed inside the semi-circular frame 81, and the two arc-shaped sliding plates 82 are arranged staggeredly. Arc-shaped plates 83 are fixedly installed at the tops of the two arc-shaped sliding plates 82 through springs. The arc-shaped plates 83 are made of rubber, and the inner sides of the arc-shaped plates 83 are set as smooth surfaces. Fixing columns 84 are fixed on the sides of the two arc-shaped sliding plates 82 away from the sliding rod 71. Two L-shaped rods 86 are slidably installed on the side of the semi-circular frame 81 away from the sliding rod 71. A through-channel plate 85 is fixed at the bottom of the L-shaped rod 86. A through-channel is opened on the outer wall of the side of the through-channel plate 85 away from the L-shaped rod 86. The fixing column 84 is slidably installed inside the through-channel of the through-channel plate 85. One end of the L-shaped rod 86 close to the sliding rod 71 is hinged with a first hinge rod 87. One end of the first hinge rod 87 away from the L-shaped rod 86 is hinged with a slider 88. The slider 88 is slidably installed on the top of the sliding rod 71, and a spring is provided between the slider 88 and the sliding rod 71. The slider 88 protrudes 2 centimeters above the top of the sliding rod 71. Through the setting of the above structure, the fixing column 84 drives the arc-shaped sliding plate 82 to rotate upward along the inner wall of the semi-circular frame 81. The arc-shaped sliding plate 82 drives the arc-shaped plate 83 to rotate upward through the spring, so that the two arc-shaped plates 83 wrap the guiding wire. When the guiding wire is shaken by an external force, the arc-shaped plate 83 buffers the external force through the compression or extension action of the spring. This buffering effect can reduce the amplitude of the shaking of the guiding wire, thereby effectively reducing the damage caused by the friction between the guiding wire and the arc-shaped clamping plate 77 when the guiding wire shakes, and further extending the service life of the guiding wire.

[0029] During use, connect the guiding wire to the low-voltage outgoing terminal 3. At this time, the guiding wire lies on the top of the vertical plate 6. Install the protective shell 4 on the top of the transformer body 1. At this time, the guiding wire is in the through hole of the protective shell 4. Rotate the screw rod 75. Since the position of the arc-shaped clamping plate 77 is restricted by the limiting rod 76, the screw rod 75 will push the arc-shaped clamping plate 77 towards the guiding wire, so that the arc-shaped clamping plate 77 clamps and fixes the guiding wire, thereby firmly fixing the guiding wire at the designated position, reducing the loosening or falling off of the guiding wire caused by external forces (such as collisions or dragging during operation by staff), which can ensure the stability of the electrical connection and avoid electrical faults or poor contact problems. At the same time, after the arc-shaped clamping plate 77 fixes the guiding wire, push the sliding rod 71 towards the protective shell 4. The sliding rod 71 drives the connecting plate 72 to move accordingly. 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 to drive the triangular block plate 73 to move upward, and the triangular block plate 73 squeezes the elastic telescopic column 74. When stopping pushing the sliding rod 71, under the elastic force of the elastic telescopic column 74, when the telescopic end of the elastic telescopic column 74 pushes the triangular block plate 73 to move 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 plate 73, so that the triangular block plate 73 restricts the position of the connecting plate 72, and the connecting plate 72 restricts the position of the sliding rod 71. And during this process, the arc-shaped clamping plate 77 drives part of the guiding wire towards the protective shell 4, so that the guiding wire between the arc-shaped clamping plate 77 and the protective shell 4 is bent. The bent part of the guiding wire is the reserved guiding wire. The bent part of the guiding wire can make the guiding wire more flexible. When an external force acts, a certain amount of stress is absorbed through the deformation of the bent part of the guiding wire, reducing the direct action of the external force on the straight part of the guiding wire, avoiding excessive stretching or twisting of the guiding wire, and reducing the probability of line damage or loosening caused by dragging by staff.

[0030] At the same time, the guiding wire will lie on the tops of the two arc-shaped plates 83. When the sliding rod 71 moves towards the protective shell 4, the sliding rod 71 will drive the slider 88 to continue moving until the slider 88 abuts against the outer wall of the protective shell 4. When the sliding rod 71 continues to move, the slider 88 will push the hinge rod one 87 to drive the L-shaped rod 86 to move upward along the outside of the semi-circular frame 81. The L-shaped rod 86 drives the through groove plate 85 to move upward. The through groove plate 85 drives the fixed column 84 to move upward. The fixed column 84 will drive the arc-shaped sliding plate 82 to rotate upward along the inner wall of the semi-circular frame 81. The arc-shaped sliding plate 82 drives the arc-shaped plate 83 to rotate upward through the spring, so that the two arc-shaped plates 83 wrap the guiding wire. When the guiding wire shakes under the action of an external force, the arc-shaped plate 83 will buffer the external force through the compression or stretching action of the spring. This buffering effect can reduce the amplitude of the shaking of the guiding wire, thereby effectively reducing the damage caused by the friction between the shaking guiding wire and the arc-shaped clamping plate 77, and further extending the service life of the guiding wire.

[0031] Please refer to 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 outgoing terminal 2.

[0032] The bending device 9 includes two first elastic telescopic rods 91. The fixed ends of the two first elastic telescopic rods 91 are slidably installed outside the protective shell 4. A pressing wheel 92 is rotatably installed between the tops of the fixed ends of the two first elastic telescopic rods 91. The bottoms of the telescopic ends of the two first elastic telescopic rods 91 are respectively hinged with second hinge rods 93. One ends of the two second hinge rods 93 away from the first elastic telescopic rods 91 are respectively hinged to the bottoms of the two slide rods 71. Through the above structure, the pressing wheel 92 presses the bent part of the guiding wire to move downward, so as to ensure that the bent part of the guiding wire is downward each time it bends. In rainy days, since the bent part of the guiding wire is downward, the guiding wire will guide the rainwater downward, thus effectively preventing the rainwater from flowing along the guiding wire to the connection end of the low-voltage outgoing terminal 3 and the guiding wire, avoiding the problem that the connection end of the low-voltage outgoing terminal 3 and the guiding wire is wetted by the rainwater, resulting in potential safety hazards.

[0033] Elastic telescopic rods 95 are fixed to the sides of the fixed ends of the two first elastic telescopic rods 91 away from the protective shell 4, and the elastic telescopic rods 95 are horizontally arranged. Baffles 94 are fixed to the sides of the telescopic ends of the two elastic telescopic rods 95 close to each other. The two baffles 94 are respectively located on both sides of the bottom of the pressing wheel 92. Through the above structure, the contact between the baffle 94 and the guiding wire can keep the guiding wire in the correct position in the pressing wheel 92, prevent the guiding wire from deviating from the action range of the pressing wheel 92 during movement, and avoid detaching from the pressing wheel 92.

[0034] During use, when the sliding rod 71 moves towards the protective housing 4, the sliding rod 71 pushes the second articulated rod 93 to drive the first elastic telescopic rod 91 to move downward along the outer wall of the protective housing 4. The first elastic telescopic rod 91 will drive the pressing wheel 92 to move downward, and the pressing wheel 92 presses the bent part of the guiding wire to move downward, so as to ensure that the bent part of the guiding wire is downward every time it bends. In rainy days, since the bent part of the guiding wire is downward, the guiding wire will guide the rainwater downward, thus effectively preventing the rainwater from flowing along the guiding wire to the low-voltage outgoing terminal 3 and the connection terminal of the guiding wire, avoiding the low-voltage outgoing terminal 3 and the connection terminal of the guiding wire from being soaked by rainwater, and preventing potential safety hazards. It should be noted that when the first elastic telescopic rod 91 drives the guiding wire to bend downward to the limit position through the pressing wheel 92 and the second articulated rod 93 continues to push the first elastic telescopic rod 91, the telescopic end of the first elastic telescopic rod 91 will be stretched; at the same time, under the elastic force of the second elastic telescopic rod 95, the telescopic end of the second elastic telescopic rod 95 will drive the baffle 94 to contact the outer walls on both sides of the guiding wire. The contact between the baffle 94 and the guiding wire can keep the guiding wire in the correct position in the pressing wheel 92, prevent the guiding wire from deviating from the action range of the pressing wheel 92 during movement, and avoid separating from the pressing wheel 92.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
