Description

Technical Field

[0001] The utility model relates to the field of electrical equipment related to work safety, and particularly relates to a gate system driven by an electrostatic discharge device. Background Art

[0002] Drug production usually requires to be carried out in a clean space. Therefore, the production area is usually isolated from other functional areas by means of a gate system. On the one hand, it can effectively reduce the entry of particulate matter into the production area and reduce the risk of cross-contamination. On the other hand, it can also prevent unauthorized personnel from entering the production area by means of identity authentication.

[0003] In addition, during the drug production process, the risk of dust explosion cannot be ignored. In drug production areas involving potential dust or gas explosion-proof risks, not only are the equipment required to have corresponding explosion-proof grades, but also additional measures need to be taken to reduce static electricity accumulation, because static electricity discharge may trigger dust or gas explosions. In order to reduce the safety risks caused by static electricity, in the prior art, an electrostatic discharge device is provided at the entrance of the production area. Operators release the static electricity on their bodies by touching the electrostatic discharge device or in other ways before entering the production area, thereby reducing the explosion risk caused by static electricity. However, currently, it mainly relies on the consciousness and standardization of operators, there is a risk of forgetting, and it cannot fully ensure that static electricity can be effectively released every time before entering.

[0004] Therefore, it is necessary to further improve the existing gate system. Summary of the Utility Model

[0005] The utility model provides a gate system driven by an electrostatic discharge device, aiming to overcome one or more of the above technical problems and / or other technical problems in the prior art.

[0006] According to one aspect of the utility model, the gate system driven by an electrostatic discharge device includes an electrostatic discharge device, a gate, a control box, and a gate driving device. Among them, the control box includes a controller. The gate driving device is signal-connected to the control box and can move the gate under the driving and control of the control box. The electrostatic discharge device is at least signal-connected to the control box and is configured to send a control signal to the controller after the operator releases the static electricity on the human body through the electrostatic discharge device, so that the gate driving device drives the gate to open. Therefore, the opening of the gate is driven by the electrostatic discharge device. Only after the operator releases the static electricity on the human body, such as by touching the electrostatic discharge device or in other ways, does the electrostatic discharge device send a control signal to the controller of the control box and open the gate. Thus, the risk that personnel enter the production area without releasing static electricity is reliably avoided.

[0007] Preferably, the control box has a locking device and a plurality of control buttons. The locking device is designed to disable the control buttons during the normal operation of the gate system and enable the control buttons to resume their functions during the abnormal operation of the gate system.

[0008] Advantageously, the locking device is designed as a physical lock in the form of a physical isolation control switch, and the physical lock can be opened by a key.

[0009] According to a preferred extended design, the electrostatic discharge device is installed on the ground or wall and electrically connected to the equipotential grounding box.

[0010] Advantageously, the electrostatic discharge device is also preferably designed as an electrostatic discharge ball.

[0011] Preferably, a palmprint recognition device is designed on the electrostatic discharge ball.

[0012] Preferably, the electrostatic discharge device further includes an electrostatic indicator for indicating the static voltage of the human body.

[0013] Advantageously, the gate driving device is designed as a motor, and the gate is designed as a rolling shutter door or a sliding door.

[0019] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the figures, for the sake of clarity, the dimensions of some elements may be exaggerated or deformed. In the figures, the same reference numerals denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0020] In addition, the described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present utility model. However, those skilled in the art will realize that the technical solutions of the present utility model may be practiced without one or more of the specific details, or other methods, elements, etc. may be employed. In other cases, well-known structures, methods, or operations are not shown or described in detail to avoid obscuring aspects of the present utility model.

[0021] Figure 1 A schematic diagram of a gate system according to the present utility model is shown. The gate system includes a gate 1, a driving device 2 designed as a motor, a control box 3, and an electrostatic discharge device 4. Here, the gate is designed as a rolling shutter door. The rolling shutter door can be quickly opened and closed, and while ensuring the sealing of the clean space for production, it can improve the access efficiency of personnel and materials. However, the gate can also be designed as other forms of doors, such as sliding doors, etc. The driving device 2 is mechanically connected to the roller of the rolling shutter door by means of a transmission mechanism. The driving device 2 is at least signal-connected to the control box 3. The signal connection can be a wired connection or a wireless connection. It can also be considered to electrically connect the driving device 2 and the control box 3 while having a signal connection.

[0022] The control box 3 mainly includes components such as a controller, a power supply, a fuse, multiple control buttons, sensors, etc. The controller receives the signals from the sensors and converts the signals into electrical signals, thereby realizing the operation control of the rolling shutter door. The fuse is used to protect the rolling shutter door system from power problems such as overcurrent, overload, and short circuit. The control buttons are the human-machine interaction components of the control box, mainly used for manually controlling the opening and closing of the rolling shutter door, and stopping the movement of the rolling shutter door. Common buttons include start buttons, stop buttons, switch buttons, etc. The sensors are mainly used to detect parameters such as the position, speed, and state of the rolling shutter door, and convert them into control signals and feedback them to the controller to ensure that the rolling shutter door remains stable during movement. Commonly used sensors include photoelectric sensors, position sensors, speed sensors, etc.

[0023] Although not shown, the gate 1 in the form of a rolling shutter door may further include a warning device for emitting warning information in an optical and / or acoustic manner. Thus, while the gate is being opened or closed, a prompt can be given to the operator in an optical and / or acoustic manner.

[0024] In addition, the gate 1 further includes a detection device for detecting personnel or objects within the gate area. The detection device can be, for example, an infrared sensor, a camera, an RFID, or an ultrasonic sensor, etc., whereby personnel or other objects located in the gate frame area can be reliably detected to avoid accidents when the gate is closed.

[0025] Here, the control box 3 also advantageously has a locking device 3-1, which is designed to disable the control buttons during the normal operation of the gate system and to enable the control buttons to resume their functions during the abnormal operation of the gate system. The locking device 3-1 is preferably designed in the form of a physical isolation control switch, such as a physical lock. However, it can also be designed in other equivalent forms, such as a password lock, etc. That is to say, during the normal operation of the gate system, the control buttons on the control box 3 are ineffective, while during the abnormal operation, for example, in the emergency situation where the static electricity release device fails, the operator can open the physical lock with a key to make the control buttons resume their functions, so that the emergency control or maintenance of the gate system can be achieved through the control buttons.

[0026] The control box 3 is also signal-connected to a static electricity release device 4 provided on the ground, and preferably can also be electrically connected. The installation position of the static electricity release device 4 can be flexibly selected according to the space and usage scenario. For example, it can also be installed on the wall and connected to an equipotential grounding box 5 to achieve grounding connection. The static electricity release device 4 is preferably designed as a static electricity release ball. The static electricity release device 4 adopts a passive circuit, which uses the static electricity on the human body to make the circuit work, and finally achieves the effect of eliminating static electricity. The operator releases the human body static electricity by touching the static electricity release device 4. After the static electricity is released, the static electricity release device 4 sends a control signal to the controller in the control box 3, thereby driving the gate 1 to open. For example, the static electricity release device 4 includes a voltage sensor for detecting the static electricity voltage. When the detected voltage is lower than a predetermined threshold, for example, zero, a corresponding control signal is triggered. It can also be considered to trigger a corresponding control signal after a predetermined duration, such as 10 seconds, after the human body touches the static electricity release device 4.

[0027] Advantageously, the gate system further includes an identity recognition system, which is preferably designed as a palmprint recognition system. The palmprint recognition system can be designed on the static electricity release ball, for example. Therefore, when the operator touches the static electricity release ball with the palm, on the one hand, the static electricity is released, and on the other hand, the identity verification is achieved. Only when the static electricity is released and the identity verification is legal, the static electricity release device 4 sends a control signal to the controller in the control box 3, thereby driving the gate 1 to open.

[0028] Although not shown, the static electricity release device 4 can also include a static electricity indicator lamp for indicating the human body static electricity voltage. In addition, the static electricity release device 4 is preferably designed to slowly release the human body static electricity to reduce the impact and harm of the static electricity release process on the human body. The static electricity release device, especially the static electricity release ball, is made of materials with a grade of 304 stainless steel or above to meet the installation requirements of a clean space.

[0029] Advantageously, the components of the static electricity discharge device 4 are selected to meet the requirements of the explosion-proof rating. The control box and the motor of the rolling shutter door are at least selected with an IP5X protection rating to meet the explosion-proof rating requirements of the pharmaceutical production area.

[0030] Figure 2 An exemplary functional module diagram of the gate system according to the present utility model is shown.

[0031] As Figure 2 shown, the gate system mainly includes a drive module, a control box, a power supply, and a static electricity discharge device. The drive module includes a motor and a transmission system and is powered by the power supply. Here, the drive module is indirectly powered by the power supply via the control box. The control box includes a controller and an operation button, and the control box is respectively signal-connected to the static electricity discharge device, an external sensor, and an identity recognition system. Here, the control box is also preferably electrically connected to the external sensor system and the identity recognition system respectively. Thus, the external sensor system and the identity recognition system are also indirectly powered by the power supply.

[0032] Overall, through the solution described in this application, since the opening of the gate system is driven by a control signal issued by the static electricity discharge device, it can ensure that the operator must release the static electricity on the body through the static electricity discharge device before entering the pharmaceutical production area with the risk of dust or gas explosion, avoiding the safety risks caused by static electricity. At the same time, various operation buttons of the existing control box are retained to ensure that in case of emergency (such as when the static electricity discharge device fails), authorized personnel can restore the button function by using a key for emergency repair and operation. In addition, by combining the static electricity discharge device with the identity recognition system, it is very convenient to perform identity verification.
