Description

Technical Field

[0001] The invention relates to the technical field of electronic devices, in particular to an energy-saving and power-saving device for a relay switch. Background Art

[0002] An electromagnetic relay is an electronic control device that works on the principle of electromagnetic induction. When the electromagnetic relay is in use, the energized coil inside it can generate magnetism, thereby forming an electromagnet, which attracts the armature to cause the elastic metal sheet connected to the armature to shift. The end of the elastic metal sheet is often connected to a contact. When the elastic metal sheet shifts, the contact will connect to the high-voltage circuit, thereby connecting the high-voltage circuit. Therefore, the electromagnetic relay connected to the low-voltage circuit can make the high-voltage circuit conductive after being energized. This is the working principle of the electromagnetic relay.

[0003] The main working step of the electromagnetic relay is to energize the coil to generate magnetism and attract the armature. In this process, the armature is initially some distance away from the energized coil, so the coil needs to pass a sufficiently large current to attract the armature. When the armature is adsorbed, only a small amount of current is needed in the coil to maintain the adsorbed state of the armature. Therefore, if the current in the circuit does not change at this time, it actually causes a waste of power. Therefore, when the electromagnetic relay needs to remain energized for a long time or needs to be frequently turned on and off, it will cause a waste of electric energy. At this time, an energy-saving and power-saving device is needed to solve the problem of waste. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes an energy-saving and power-saving device for a relay switch, which can provide a large current in the circuit when the electromagnetic relay is energized, so that the energized coil in the electromagnetic relay can generate a sufficiently large magnetism to attract the armature. After the armature is adsorbed, the current in the circuit can be reduced to keep the armature in an adsorbed state while reducing the loss of electrical energy in the entire circuit, thereby achieving a power saving effect.

[0006] Preferably, the resistance adjustment assembly further includes a first limit block and a second limit block, the first limit block and the second limit block are both fixedly connected to the variable resistor slider, and the blocking rod is located between the first limit block and the second limit block.

[0007] Preferably, the adjustment assembly includes a screw and a knob, the screw is rotatably connected to the box, the knob is rotatably connected to the outer wall of the box, the knob is fixedly connected to the screw, and the screw is threadedly connected to the slide.

[0008] Preferably, the adjustment assembly further comprises a threaded sleeve, and the threaded sleeve is threadedly connected to the fixing tube.

[0009] Preferably, the adjustment assembly further comprises a friction block and a third spring, wherein the friction block is slidably connected to the inner wall of the box, and the third spring is fixedly connected between the friction block and the inner wall of the box.

[0010] Preferably, the adjustment assembly further comprises a first scale and a second scale, wherein the first scale is arranged on the inner wall of the box body and cooperates with the slide, and the second scale is arranged on the fixed cylinder and cooperates with the threaded sleeve.

[0011] Preferably, the friction block is slidably connected to the threaded sleeve, and the surfaces of the friction block and the threaded sleeve are both provided with frosted patterns.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First, in the present invention, by setting a driving component, when the power supply is started, the low-speed motor will also be energized, so that its output shaft rotates, driving the first spring to rotate. The rotation of the first spring will drive the tooth block to swing, and the tooth block is stuck in the limit tooth. Therefore, the swing of the tooth block will drive the limit tooth and the rotating ring to rotate. The rotation of the rotating ring will drive the swing rod to swing. During the swing of the swing rod, the blocking rod will be pushed. At this time, the blocking rod will be pushed and thus move. The blocking rod first resists the second limit block, and then pushes the second limit block and the rheostat slider to move the rheostat slider. When the rheostat slider moves, the resistance of the sliding rheostat increases, so the resistance in the entire circuit increases and the current decreases. Since the energized coil in the relay has already adsorbed the armature, only a small magnetic force is needed to keep the armature adsorbed at this time. Therefore, although the current is reduced at this time, the magnetic field generated by the energized coil is small, but the armature will still remain adsorbed, and the current in the circuit is reduced, and the voltage remains unchanged, so the power of the circuit is reduced, achieving the effect of saving electricity.

[0014] Second: In the present invention, the swing of the rocker arm will drive the movement of the baffle rod, and the movement of the baffle rod will drive the movement of the telescopic rod. When the baffle rod is against the threaded sleeve, the baffle rod can no longer move. At this time, although the output shaft of the low-speed motor still drives the tooth block to rotate, the rocker arm can no longer swing and the swivel ring can no longer rotate. Therefore, the first spring will continue to twist to make the tooth block move between the multiple limit teeth, and under the action of the second spring, the telescopic rod will have a tendency to reset, so the baffle rod will be pushed in the reset direction, and as the tooth block moves in the multiple limit teeth, the telescopic rod will show a reciprocating shaking effect, so the baffle rod will also shake back and forth, but the baffle rod does not contact the first limit block during the shaking process, so the rheostat slider will not move with the shaking of the baffle rod, so the resistance of the sliding rheostat can remain stable.

[0015] Third: In the present invention, when the electromagnetic relay is no longer in use and needs to be powered off, the rheostat slider will be reset. In this process, the power supply needs to be turned off first. After the power supply is turned off, the low-speed motor is turned off, so the gear block no longer rotates. At this time, the elastic force of the second spring will completely reset the telescopic rod, thereby pushing the baffle rod to reset. In this process, the baffle rod first resists the first limit block, and then the first limit block and the rheostat slider move together until they return to the initial position. At this time, the sliding rheostat returns to the initial resistance value, and when the electromagnetic relay needs to be started next time, the initial current can still be the maximum value.

[0016] Fourthly, in the present invention, when the specifications of the electromagnetic relay are different, the current for starting the electromagnetic relay and maintaining the armature to be adsorbed are different. Therefore, the initial position of the rheostat slider and the distance the rheostat slider moves can be adjusted according to the specifications of the electromagnetic relay. The slide can be moved by turning the knob. The movement of the slide can drive the fixed cylinder and the telescopic rod to move, thereby adjusting the initial position of the rheostat slider, that is, achieving the effect of adjusting the initial resistance of the sliding rheostat. In order to adjust the distance the rheostat slider moves, the box cover can be opened and the friction block can be pushed so that the friction block does not contact the threaded sleeve. At this time, the threaded sleeve is rotated to change the spacing between the threaded sleeve and the stop rod. Because the stop rod can no longer push the telescopic rod when it moves to contact the threaded sleeve, this spacing is the distance that the rheostat slider can move. The scale units marked on the first scale and the second scale are resistance values. By observing the first scale and the second scale, it can be known that when the slide moves, the change of the initial resistance value of the sliding rheostat and when the threaded sleeve moves, the change of the resistance range that the rheostat slider can adjust can be known.

[0027] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides an energy-saving and power-saving device for a relay switch through improvement. The technical solution of the present invention is:

[0029] like Figure 1-Figure 7As shown, an energy-saving and power-saving device for a relay switch comprises a box body 1, a box cover 2 is hingedly connected to the box body 1, a power supply assembly 3 is arranged inside the box body 1, the power supply assembly 3 comprises a power supply 31, a sliding rheostat 32, a rheostat slider 33 and a wire clamp 34, the power supply 31 and the sliding rheostat 32 are fixedly connected to the inner wall of the box body 1, the power supply 31 is electrically connected to the sliding rheostat 32, the rheostat slider 33 is slidably connected to the sliding rheostat 32, two wire clamps 34 are arranged outside the box body 1, the two wire clamps 34 are electrically connected to the power supply 31, a driving assembly 4 is arranged inside the box body 1, the driving assembly 4 comprises a wire 41, a low-speed motor 42, a bracket 43, a swivel 44, a limit tooth 45, a first spring 46, a tooth block 47, a rocker 48 and a baffle 49, the wire 41 is electrically connected to the power supply 31, the low-speed motor 42 is fixedly connected to the inner wall of the box body 1, the low-speed motor 42 is connected to the wire The wire 41 is electrically connected, the bracket 43 is fixedly connected to the inner wall of the box body 1, the swivel 44 is rotatably connected to the bracket 43, a plurality of limit teeth 45 are distributed in a ring array inside the swivel 44, the first spring 46 is fixedly connected to the output shaft of the low-speed motor 42, the tooth block 47 is fixedly connected to the first spring 46, the rocker 48 is fixedly connected to the swivel 44, the stop rod 49 is slidably connected to the rheostat slider 33, and a resistance adjustment component 5 is arranged on the inner wall of the box body 1. The resistance adjustment component 5 includes a slide 51, a fixed cylinder 52, a telescopic rod 53 and a second spring 54. The slide 51 is slidably connected to the inner wall of the box body 1, the fixed cylinder 52 is fixedly connected to the slide 51, the telescopic rod 53 is slidably connected to the inside of the fixed cylinder 52, the second spring 54 is fixedly connected between the telescopic rod 53 and the inner wall of the fixed cylinder 52, the telescopic rod 53 is fixedly connected to the stop rod 49, and an adjustment component 6 is arranged inside the box body 1.

[0030] The rheostat slider 33 on the sliding rheostat 32 can move, and after the rheostat slider 33 moves, the resistance of the sliding rheostat 32 will increase. Therefore, when the electromagnetic relay is connected to the device, the sliding rheostat 32 is first connected to the circuit with a small resistance, so that the coil in the relay generates a large current and forms a strong magnetic field to attract the armature, so that the relay works normally. Then the rheostat slider 33 moves, and the sliding rheostat 32 is transformed into a large resistance, which reduces the coil current of the relay and reduces the magnetic field. However, since the armature has been attracted at this time, the reduction in the magnetic field can also keep the armature attracted by the coil. However, since the current is reduced in this process, the power of the device is reduced, achieving a power saving effect.

[0031] Furthermore, the resistance adjustment component 5 also includes a first limit block 55 and a second limit block 56, which are both fixedly connected to the rheostat slider 33, and the stopper 49 is located between the first limit block 55 and the second limit block 56. When the swing rod 48 swings and drives the stopper 49 to move, the stopper 49 needs to first abut against the second limit block 56 before it can drive the rheostat slider 33 to move. The swing of the swing rod 48 will drive the stopper 49 to move, and the movement of the stopper 49 will drive the telescopic rod 53 to move. When the stopper 49 abuts against the threaded sleeve 63, the stopper 49 can no longer move. At this time, although the output shaft of the low-speed motor 42 still drives the gear block 47 to rotate, However, the rocker arm 48 can no longer swing, and the swivel ring 44 can no longer rotate, so the first spring 46 will continue to twist to make the tooth block 47 move between the multiple limit teeth 45, and under the action of the second spring 54, the telescopic rod 53 will have a tendency to reset, so it will push the blocking rod 49 in the reset direction, and as the tooth block 47 moves in the multiple limit teeth 45, the telescopic rod 53 will show a reciprocating shaking effect, so the blocking rod 49 will also shake back and forth, but the blocking rod 49 did not contact the first limit block 55 during the shaking process, so the rheostat slider 33 will not move with the shaking of the blocking rod 49, so the resistance of the sliding rheostat 32 can remain stable.

[0032] Furthermore, the adjustment assembly 6 includes a screw 61 and a knob 67 . The screw 61 is rotatably connected to the box body 1 . The knob 67 is rotatably connected to the outer wall of the box body 1 . The knob 67 is fixedly connected to the screw 61 . The screw 61 is threadedly connected to the slide 51 .

[0033] Furthermore, the adjustment component 6 also includes a threaded sleeve 63, which is threadedly connected to the fixed tube 52. Rotating the threaded sleeve 63 can change the distance between the threaded sleeve 63 and the blocking rod 49. Because the blocking rod 49 can no longer push the telescopic rod 53 when it moves to contact the threaded sleeve 63, this distance is the distance that the rheostat slider 33 can move.

[0034] Furthermore, the adjustment assembly 6 also includes a friction block 65 and a third spring 66 . The friction block 65 is slidably connected to the inner wall of the box body 1 , and the third spring 66 is fixedly connected between the friction block 65 and the inner wall of the box body 1 .

[0035] Furthermore, the adjustment component 6 also includes a first scale 62 and a second scale 64. The first scale 62 is arranged on the inner wall of the box body 1, and the first scale 62 cooperates with the slide 51. The second scale 64 is arranged on the fixed tube 52, and the second scale 64 cooperates with the threaded sleeve 63. The scale units marked on the first scale 62 and the second scale 64 are resistance values. By observing the first scale 62 and the second scale 64, it can be known that when the slide 51 moves, the initial resistance value of the sliding rheostat 32 changes, and when the threaded sleeve 63 moves, the resistance value range that can be adjusted by the rheostat slider 33 changes.

[0036] Furthermore, the friction block 65 is slidably connected to the threaded sleeve 63, and the surfaces of the friction block 65 and the threaded sleeve 63 are both provided with frosted patterns. When the friction block 65 and the threaded sleeve 63 are in contact, there is a large static friction force between the two, so the threaded sleeve 63 is not easy to loosen. When the position of the threaded sleeve 63 needs to be adjusted, the friction block 65 can be pushed first so that the friction block 65 does not contact the threaded sleeve 63.

[0037] The specific working method is: firstly, the two wire clamps 34 are connected to the electromagnetic relay, so that the electromagnetic relay is electrically connected to the power saving device. When the electromagnetic relay needs to be started, the power supply 31 can be controlled to be turned on. When the power supply 31 is started, the electromagnetic relay will be energized, so that the coil inside it is energized, so that the armature inside the relay is attracted, so that the high-voltage circuit connected to the relay is turned on. When the power supply 31 is started, the low-speed motor 42 will also be energized, so that its output shaft rotates, driving the first spring 46 to rotate. The rotation of the first spring 46 will drive the tooth block 47 to swing. The tooth block 47 is stuck in the limit tooth 45. Therefore, the swing of the tooth block 47 will drive the limit tooth 45 and the rotating ring 44 to rotate. The rotation of the rotating ring 44 will drive the swing rod 4 8 swings, and the swing rod 48 pushes the blocking rod 49 during the swinging process. At this time, the blocking rod 49 will be pushed and thus move. The blocking rod 49 first abuts against the second limit block 56, and then pushes the second limit block 56 and the rheostat slider 33 to move the rheostat slider 33. When the rheostat slider 33 moves, the resistance of the sliding rheostat 32 increases, so the resistance in the entire circuit increases and the current decreases. Since the energized coil in the relay has already adsorbed the armature, only a smaller magnetic force is needed to keep the armature adsorbed at this time. Therefore, although the current is reduced at this time, the magnetic field generated by the energized coil is smaller, but the armature will still remain adsorbed, and the current in the circuit is reduced, and the voltage remains unchanged, so the power of the circuit is reduced, achieving the effect of saving electricity.

[0038] The swing of the swing rod 48 will drive the blocking rod 49 to move, and the movement of the blocking rod 49 will drive the telescopic rod 53 to move. When the blocking rod 49 is against the threaded sleeve 63, the blocking rod 49 can no longer move. At this time, although the output shaft of the low-speed motor 42 still drives the tooth block 47 to rotate, the swing rod 48 can no longer swing, and the swivel ring 44 can no longer rotate. Therefore, the first spring 46 will continue to twist to make the tooth block 47 move between the multiple limit teeth 45, and under the action of the second spring 54, the telescopic rod 53 will have a tendency to reset, so it will push the blocking rod 49 in the reset direction, and along with the movement of the tooth block 47 in the multiple limit teeth 45, the telescopic rod 53 will show a reciprocating shaking effect, so the blocking rod 49 will also shake back and forth, but the blocking rod 49 does not contact the first limit block 55 during the shaking process, so the resistor slider 33 will not move with the shaking of the blocking rod 49, so the resistance of the sliding resistor 32 can remain stable.

[0039] When the electromagnetic relay is no longer in use and needs to be powered off, the rheostat slider 33 will be reset. In this process, the power supply 31 needs to be turned off first. After the power supply 31 is turned off, the low-speed motor 42 is turned off, so the tooth block 47 no longer rotates. At this time, the elastic force of the second spring 54 will completely reset the telescopic rod 53, thereby pushing the blocking rod 49 to reset. In this process, the blocking rod 49 first resists the first limit block 55, and then the first limit block 55 and the rheostat slider 33 move together until they return to the initial position. At this time, the sliding rheostat 32 returns to the initial resistance value, and when the electromagnetic relay needs to be started next time, the initial current can still be the maximum value.

[0040] When the specifications of the electromagnetic relay are different, the current for starting the electromagnetic relay and maintaining the armature to be attracted are different. Therefore, the initial position of the rheostat slider 33 and the moving distance of the rheostat slider 33 can be adjusted according to the specifications of the electromagnetic relay. It is only necessary to turn the knob 67 to move the slide 51. The movement of the slide 51 can drive the fixed cylinder 52 and the telescopic rod 53 to move, thereby adjusting the initial position of the rheostat slider 33, that is, achieving the effect of adjusting the initial resistance of the sliding rheostat 32. In order to adjust the moving distance of the rheostat slider 33, the box cover 2 can be opened, and the friction block 65 can be pushed to make the friction block 65 is not in contact with the threaded sleeve 63. At this time, the threaded sleeve 63 is rotated again to change the distance between the threaded sleeve 63 and the blocking rod 49. Because the blocking rod 49 can no longer push the telescopic rod 53 when it moves to contact with the threaded sleeve 63, this distance is the distance that the rheostat slider 33 can move. The scale units marked on the first scale 62 and the second scale 64 are resistance values. By observing the first scale 62 and the second scale 64, it can be known that when the slide 51 moves, the initial resistance value of the sliding rheostat 32 changes, and when the threaded sleeve 63 moves, the resistance value range that can be adjusted by the rheostat slider 33 changes.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
