[0002] Static electricity is a phenomenon caused by an imbalance in electrical charge on the surface of an object. Static electricity can cause numerous problems in industry and daily life, including discomfort, safety hazards, and even fires or explosions. In the electronics industry, the release of static electricity can damage precision components, while in the chemical industry, the accumulation of static electricity can cause explosions or fires. Therefore, effectively dissipating and controlling static electricity on the human body has become a pressing challenge in these industries.

[0003] In the existing technology, there have been technologies including anti-static wristbands and human body anti-static balls, which have achieved the beneficial effect of reducing or controlling static electricity to a certain extent. However, in the existing technology, there is no technology that takes the human body as the main body and aims to solve the problem of eliminating the electric shock sensation caused by static electricity to the human body, especially for industries such as urban rail transit train drivers who need to get up and sit frequently and frequently touch switch handles, which may cause electric shock sensation.

[0004] Therefore, a movable device for discharging static electricity in urban rail transit trains is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a movable device for releasing static electricity in urban rail transit trains, including a wristband 1, which is made of elastic fabric material. The wristband is made of high-elastic non-woven fabric to adapt to the use of different drivers and increase the wearing comfort.

[0025] Furthermore, a snap plate 4 is movably mounted on the wristband 1, and a conductive plate 2 is movably mounted on the snap plate 4. The conductive plate 2 is made of a highly conductive metal material and is arc-shaped. The arc-shaped conductive plate 2 is used to better fit the shape of the human wrist. The width of the conductive plate 2 is consistent with the width of the wristband to increase wearing comfort. The high conductivity of the conductive plate 2 can quickly and easily conduct electric charges. At the same time, the snap plate 4 is detachable, which makes it easy for the wearer to clean the wristband 1 in time when not in use.

[0026] Furthermore, a shorter wire 7 is installed on the conductive plate 2. The shorter wire 7 is made of copper soft wire, and its surface is wrapped with insulating material and its length is ten centimeters. A magnetic iron block 3 is installed on the shorter wire 7. The magnetic iron block 3 is magnetically connected to another magnetic iron block 3. A longer wire 6 is installed on the other magnetic iron block 3. The longer wire 6 is made of copper soft wire, and its surface is wrapped with insulating material and its length is four meters. A grounding device 8 is installed on one end of the longer wire 6, and the grounding device 8 is installed on the floor 16. The conductive plate 2 is used to transfer the charge of the human body to the magnetic iron block 3, and then to the longer wire 6 through the magnetic iron block 3, and then to the grounding device 8 through the longer wire 6, and finally to the floor 16 through the grounding device 8, so that static electricity can be released. At the same time, the two magnetic iron blocks 3 can attract and attract each other within a diameter of 2 cm of the conductive plate, and can transfer static charge after attraction.

[0027] Furthermore, an operating table 15 is installed on the floor 16, a partition 11 is installed on the operating table 15, a fixed bracket 9 is installed on the partition 11, a rebound spring 5 is installed on the fixed bracket 9, a roller 10 is rotatably installed on the rebound spring 5, a longer wire 6 is wound around the roller 10, and the deformation degree of the rebound spring 5 is adjustable so that the roller 10 is controlled to retract the extended longer wire 6 to the initial length position, and the fixed bracket 9 is set at the lower right side of the driver's cab for convenient grounding.

[0028] Example 2: On the basis of Example 1, in order to enable the roller 10 to adapt to the use of different users, two negative pressure cylinders 12 are symmetrically provided on the partition 11. The bottom sides of the two negative pressure cylinders 12 are funnel-shaped and in contact with the upper surface of the operating table 15. A threaded rod 13 is threadedly installed on the negative pressure cylinder 12, and a rubber piston 14 is rotatably installed on the bottom side of the threaded rod 13. The rubber piston 14 is slidably installed on the inner wall of the negative pressure cylinder 12. After moving the partition 11 to a suitable position, it is only necessary to manually rotate the threaded rod 13. The threaded rod 13 drives the rubber piston 14 to move upward, thereby reducing the pressure in the space enclosed by the negative pressure cylinder 12 and the operating table 15, and then the partition 11 can be conveniently fixed on the operating table 15 for use. It is not only convenient and quick, but also practical and simple. The remaining features are the same as those of Example 1.

[0029] The working principle is as follows: the bracelet 1 connects the conductive plate 2 and the shorter wire 7 through the snap plate 4, the conductive plate 2 contacts the human wrist on the inside of the bracelet 1, and the other end of the shorter wire 7 is equipped with a magnetic iron block 3. The above components constitute the human wear part, which is worn on the right wrist of the human body. One end of the longer wire 6 is grounded and set under the driving console, and the other end of the longer wire 6 is equipped with a magnetic iron block 3 and set on the upper right side of the driving console. The longer wire 6 is wound on the roller 10, and the roller 10 retracts the longer wire 6 through the limiting device of the rebound spring 5. When the driver needs to get up to open or close the door, the right wrist leaves the original position. At this time, the bracelet 1 drives the wire to move. When the wrist leaves the specified position, the wire is tightened and the magnetic iron block 3 is disconnected. At this time, the static electricity is released when a stand-up is completed. When the magnetic iron block 3 After disconnection, the rebound spring 5 starts to move under force, causing the roller to retract the longer wire 6. When it is retracted to its original position, the rebound spring 5 returns to its unstressed state and waits for the next force. When the driver finishes opening and closing the door and enters the driver's cab, his wrist is close to the original position. The driver only needs to move his wrist slightly to re-engage the magnetic iron block 3. When the roller 10 needs to be moved, it is only necessary to manually move the partition 11 to the specified position, and then make the negative pressure cylinder 12 on the partition 11 fit with the surface of the operating table 15, and then manually rotate the threaded rod 13 to move it upward. The threaded rod 13 and the rubber piston 14 slide on the inner wall of the negative pressure cylinder 12, thereby quickly reducing the pressure in the space enclosed by the negative pressure cylinder 12 and the operating table 15, so that the partition 11 can be fixed on the operating table 15 for use.
