Description

Technical Field

[0001] This utility model relates to the field of aerial robot technology, and in particular to an activation switch device for an aerial explosion-proof transport robot. Background Technology

[0002] Explosion-proof handling robots are robots that enable automated material handling in flammable and explosive environments.

[0003] Currently, such as Figure 1 As shown, existing aerial explosion-proof handling robots typically include a walking mechanism 2, a power supply battery 3, an explosion-proof housing 4, an electrical control box, a lifting system, and a handling mechanism. The walking mechanism 2 is slidably connected to the aerial track 1 and can move along the track 1. The explosion-proof housing 4 is connected to the bottom of the walking mechanism 2. The lifting system is mounted on the explosion-proof housing 4, and its lifting end is connected to the handling mechanism. The lifting system is used to lift the handling mechanism, which is used to move objects. The electrical control box is located inside the explosion-proof housing 4 and is used to control the independent operation of the lifting system, handling mechanism, and walking mechanism 2 of the explosion-proof handling robot. The power supply battery 3 is located inside the explosion-proof housing 4 and is used to power the electrical control box. When the power supply battery 3 is turned on, the aerial explosion-proof handling robot starts operating; when the power supply battery 3 is turned off, the aerial explosion-proof handling robot enters sleep mode. However, existing aerial explosion-proof handling robots require manual opening or closing of their power supply battery 3 during use; they cannot automatically open or close the power supply battery 3. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an activation switch device for an aerial explosion-proof handling robot, which aims to solve the technical problem that existing aerial explosion-proof handling robots require manual opening or closing of their power supply batteries during use, and cannot automatically open or close their power supply batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An activation switch device for an aerial explosion-proof handling robot includes a magnetic switch, a drive unit, a turntable, and a permanent magnet. The magnetic switch is mounted on a power supply battery that moves with the robot and provides power to it, and is electrically connected to the power supply battery. The drive unit is positioned on the robot's track without interfering with its movement, and its output is connected to the turntable. The permanent magnet is mounted on the turntable, and its two ends have different magnetic poles. The drive unit drives the turntable to rotate the permanent magnet, allowing the permanent magnet's magnetic poles to attract or repel the magnetic switch. When the first magnetic pole of the permanent magnet attracts the magnetic switch, the power supply battery is activated and powered on; when the second magnetic pole of the permanent magnet repels the magnetic switch, the power supply battery is deactivated.

[0007] Furthermore, the activation switch device also includes a sensor, which is mounted on the track via a bracket, and the sensor is used to detect the rotation angle of the turntable.

[0008] Furthermore, the sensor is a slotted photoelectric switch, and the turntable is provided with two slots, each slot penetrating the opposite surface of the turntable. The two slots are symmetrical about the center of the turntable, and the rotation of the turntable allows the slots to pass through the U-shaped slot of the slotted photoelectric switch.

[0009] Furthermore, the slot is an arc-shaped slot, and the arc-shaped slot is concentric with the turntable.

[0010] Furthermore, the permanent magnet is detachably connected to the turntable.

[0011] Furthermore, the turntable and the permanent magnet are connected and fixed by screws.

[0012] Furthermore, a groove is formed on the surface of the second end of the permanent magnet facing away from the turntable, and the groove reduces the wall thickness of the permanent magnet connected to the screw.

[0013] Furthermore, the permanent magnet and the magnetic switch are perpendicular to each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a magnetic switch as the power supply battery switch for an aerial explosion-proof transport robot. Since the robot's operation and sleep mode are controlled by its electrical control box, which is powered by the battery, the robot operates when the battery is activated to supply power to the control box, and shuts down when the battery is deactivated. When the drive unit drives the turntable to rotate the permanent magnet, causing the second pole of the permanent magnet to attract the magnetic switch fixed to the battery, the magnetic switch conducts the circuit, activating the battery and turning on power. When the drive unit drives the turntable to rotate the permanent magnet, causing the first pole of the permanent magnet to repel the magnetic switch, the magnetic switch cuts off the circuit, and the battery stops supplying power.

[0016] In summary, the activation switch device of this utility model can automatically turn on or off the power supply battery of the aerial explosion-proof handling robot, thereby automatically activating or deactivating the operation of the aerial explosion-proof handling robot.

[0025] In this invention, unless otherwise expressly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0026] Please refer to Figure 2 - Figure 4 This utility model provides an activation switch device for an aerial explosion-proof transport robot, including a magnetic switch 5, a drive unit 51, a turntable 52, and a permanent magnet 53.

[0027] The magnetic switch 5 is fixed to the power supply battery 3, which moves with the aerial explosion-proof transport robot and provides power to it. The power supply battery 3 is fixed inside the explosion-proof box 4, and the magnetic switch 5 is electrically connected to the power supply circuit of the power supply battery 3. The drive unit 51 is set on the track 1 on which the aerial explosion-proof transport robot moves and does not interfere with the robot's movement. The power for the aerial explosion-proof transport robot to move along the track 1 comes from the walking mechanism 2. The output end of the drive unit 51 is connected to the turntable 52. The permanent magnet 53 is set on the turntable 52. The two ends of the permanent magnet 53 have different magnetic poles: the first end of the permanent magnet 53 is the N pole, and the second end of the permanent magnet 53 is the S pole. The drive unit 51 is a drive motor used to drive the turntable 52 to rotate the permanent magnet 53 so that the magnetic poles of the permanent magnet 53 can attract or repel the magnetic switch 5.

[0028] It should be noted that the drive unit 51 is not powered by the power supply battery 3 of the aerial explosion-proof transport robot, but by a power source on the ground.

[0029] The magnetic switch 5 in this embodiment is a bistable magnetic switch 5, which is a magnetic induction device that uses changes in magnetic field to trigger and maintain the switching state. Its core feature is that it can maintain the state without continuous power supply and achieve state switching by triggering with an external magnetic field.

[0030] It should be noted that the structure and working principle of the bistable magnetic switch 5 belong to existing technology.

[0031] Here's a brief explanation of the structure and working principle of the bistable magnetic switch 5: The bistable magnetic switch 5 consists of a reed switch (a soft magnetic contact sealed inside a glass tube) and two small magnets with opposite polarities. When the bistable magnetic switch 5 is in operation, if the polarity of the external magnetic field is opposite to that of the small magnet inside the reed switch (e.g., the internal magnet is N, the external magnet is S), the magnetic fields are superimposed and strengthened. The total magnetic field strength exceeds the closing threshold of the reed switch contact, and the contact closes and remains closed (even if the external magnetic field is removed, the residual magnetic field of the small magnet inside the reed switch maintains the closed state). If the polarity of the external magnetic field is the same as that of the small magnet inside the reed switch (e.g., the internal magnet is N, the external magnet is N), the magnetic fields cancel each other out and weaken. The total magnetic field strength is below the closing threshold of the reed switch contact, and the contact opens and remains open (the residual magnetic field of the small magnet inside the reed switch remains open).

[0032] This invention uses a magnetic switch 5 as the switch for the power supply battery 3 of the aerial explosion-proof transport robot. Since the operation or hibernation of the aerial explosion-proof transport robot is controlled by its electrical control box, which is powered by its power supply battery 3, the aerial explosion-proof transport robot will run when the power supply battery 3 is activated to supply power to the electrical control box, and will hibernate when the power supply battery 3 is turned off to supply power to the electrical control box.

[0033] When the first magnetic pole of the permanent magnet 53 attracts the magnetic switch 5, the power supply battery 3 is activated and turns on. When the second magnetic pole of the permanent magnet 53 repels the magnetic switch 5, the power supply battery 3 is turned off. In the initial state (when the aerial explosion-proof transport robot is not running), the drive unit 51 is not started, the magnetic switch 5 fixed on the power supply battery 3 is close to the first end of the permanent magnet 53, and the magnetic switch 5 repels the first magnetic pole of the permanent magnet 53, cutting off the circuit, and the power supply battery 3 is in a stopped state. When it is necessary to activate the power supply battery 3, the drive unit 51 drives the turntable 52 to rotate 180° clockwise, so that the second end of the permanent magnet 53 is close to the magnetic switch 5. At this time, the second magnetic pole of the permanent magnet 53 attracts the magnetic switch 5, causing the internal spring of the magnetic switch 5 to close, the magnetic switch 5 to conduct the circuit, activate the power supply battery 3 and turn on, thereby activating the operation of the aerial explosion-proof transport robot. After the aerial explosion-proof transport robot completes its operation along track 1, the control box controls the robot to move along track 1 to the position of permanent magnet 53, aligning the magnetic switch 5 on the power supply battery 3 of the aerial explosion-proof transport robot with permanent magnet 53. At this time, the drive unit 51 drives the turntable 52 to rotate 180° in the opposite direction, causing the first end magnetic pole of permanent magnet 53 to repel the magnetic switch 5, thereby breaking the contacts inside the magnetic switch 5. At this time, the power supply battery 3 stops supplying power, thus putting the aerial explosion-proof transport robot into a dormant state.

[0034] In summary, the activation switch device of this utility model can automatically turn on or off the power supply battery 3 of the aerial explosion-proof handling robot, thereby automatically activating or deactivating the operation of the aerial explosion-proof handling robot.

[0035] In this embodiment, the activation switch device also includes a sensor electrically connected to the drive unit 51, which is powered by a ground-based power source. The sensor is mounted on the track 1 via a bracket; specifically, one end of the bracket is fixed to the top of the track 1, and the sensor is fixed to the other end of the bracket. The bracket and sensor do not interfere with the aerial explosion-proof transport robot's movement along the track 1. The sensor detects the rotation angle of the turntable 52, thereby facilitating the control of the first or second end of the permanent magnet 53 to rotate closer to the magnetic switch 5. The sensor is a slotted photoelectric switch 54. The turntable 52 has two slots, each penetrating the opposite surface of the turntable 52. The two slots are symmetrical about the center of the turntable 52. The rotation of the turntable 52 allows the slots to pass through the U-shaped slot of the slotted photoelectric switch 54. Specifically, the two slots are left slot 520 and right slot 521. In the initial state, the right slot 521 of the turntable 52 is located in the U-shaped slot of the slot-type photoelectric switch 54. The first end of the permanent magnet 53 repels the magnetic switch 5, the internal contacts of the magnetic switch 5 are open, and the power supply battery 3 is in a non-powered state. When the turntable 52 rotates 180° forward under the drive of the drive unit 51, the left slot 520 is located in the U-shaped slot of the slot-type photoelectric switch 54. The laser emitted by the slot-type photoelectric switch 54 is not blocked by the turntable 52. At this time, the slot-type photoelectric switch 54 feeds a signal to the drive unit 51 to stop the drive of the turntable 52, ensuring that the second end of the permanent magnet 53 is close to the magnetic switch 5, so that the second end of the permanent magnet 53 attracts the magnetic switch 5. At this time, the internal contacts of the magnetic switch 5 are closed, activating the power supply battery 3 to supply power to the control box. When the turntable 52 rotates 180° in the opposite direction under the drive of the drive unit 51, the right slot 521 returns to its original position, causing the first end of the permanent magnet 53 to approach the magnetic switch 5.

[0036] In this embodiment, the slot is an arc-shaped slot, which is concentric with the turntable 52. Since the two arc-shaped slots are symmetrical about the center of the turntable 52, it can be ensured that the light path of the slot-shaped photoelectric switch 54 is blocked for the same time.

[0037] In this embodiment, the permanent magnet 53 is detachably connected to the turntable 52, which facilitates the disassembly of the permanent magnet 53. Specifically, the turntable 52 and the permanent magnet 53 are fixed together by screws.

[0038] In this embodiment, a groove 530 is formed on the surface of the second end of the permanent magnet 53 facing away from the turntable 52. The groove 530 reduces the wall thickness of the connection between the permanent magnet 53 and the screw, thereby facilitating the connection between the screw and the permanent magnet 53.

[0039] In this embodiment, the permanent magnet 53 and the magnetic switch 5 are perpendicular to each other, which can reduce the alignment accuracy between the permanent magnet 53 and the magnetic switch 5.

[0040] In summary, when the aerial explosion-proof transport robot is used in flammable and explosive environments, the rotation angle of the drive unit 51 can be controlled by a remote controller, causing one end of the permanent magnet 53 to attract with the magnetic switch 5, activating the power supply battery 3 to power the control box of the aerial explosion-proof transport robot, thus achieving automatic start-up. Conversely, controlling the rotation angle of the drive unit 51 by the remote controller causes the other end of the permanent magnet 53 to repel the magnetic switch 5, disconnecting the power supply battery 3, thus automatically stopping the aerial explosion-proof transport robot. This eliminates the need for an operator to enter a flammable and explosive environment to control the robot's start-up or shutdown, ensuring the robot's operational safety in such environments.
