Abstract
Description

[0002] Currently, with the development of the photovoltaic industry, in order to continuously improve production capacity and optimize the equipment structure, the length and height of the equipment continue to increase. For example, the length of wet equipment reaches 25 meters, and the height of tube equipment reaches 4.5 meters. Moreover, the internal structure of the equipment is complex, and it is not easy to detect when employees enter the equipment for maintenance operations.
[0003] To prevent mechanical injuries, requirements for hanging warning signs are put forward for operators to prevent personnel from misoperating. At the same time, safety doors are designed for the equipment, that is, when the safety door is opened, the equipment automatically stops. However, due to various reasons (such as emergency repairs, inconvenient access to the sign due to its far position, etc.), there will be situations where the warning sign is forgotten to be hung, and there is a great risk of the safety door being accidentally closed in a narrow space or when someone fails to observe that there are people working inside. When personnel are working inside and there is a situation where someone misoperates the equipment to start, safety accidents of personnel suffering mechanical injuries will occur, and even threaten people's lives.
[0004] It can be seen that through simple placement of warning signs, mechanical injury accidents caused by misoperations cannot be completely avoided. Therefore, there is an urgent need for a safety protection system for mechanical equipment to solve the above problems. Utility Model Content

The following will refer to the drawings and combine the embodiments to detail the present application.
[0024] Please refer to Figure 1 , a mechanical equipment safety protection system includes: an equipment main body 1, a safety door 2, and is characterized in that: a mechanical motion device 3 is provided inside the equipment main body 1, a control console 4 for controlling the mechanical motion device 3 is provided outside the equipment main body 1, a sensor 5 is provided on the safety door 2, and a safety button 6 is provided inside the equipment main body 1; the sensor 5 is connected to the safety button 6, the safety button 6 is respectively connected to the mechanical motion device 3 and the control console 4, the sensor 5 is used to send a start signal to the safety button 6 when the safety door 2 is opened, and the safety button 6 is used to control the mechanical motion device 3 to stop moving and the control console 4 to stop being used when receiving the start signal.

Among them, the console 4 is arranged on the outer surface of the equipment main body 1, the mechanical motion device 3 is arranged inside the equipment main body 1, the safety door 2 is used to connect the inside and the outside of the equipment main body 1, the sensor 5 is arranged on the safety door 2 and is used to sense the opening and closing of the safety door 2, the safety button 6 is arranged inside the equipment main body 1, the sensor 5 is connected to the safety button 6, the safety button 6 is respectively connected to the mechanical motion device 3 and the console 4. When the safety door 2 is opened, the sensor 5 senses an opening signal and sends a start signal to the safety button 6 in response to sensing the opening signal. When the safety button 6 receives the start signal, it controls the mechanical motion device 3 to stop moving and the console 4 to stop being used.
[0026] It can be seen that in the embodiment of the present application, by designing a safety button inside the equipment and forming a linkage with the safety door, the function of the safety button can be automatically activated when the safety door is opened and the staff enters the equipment main body, cutting off the mechanical motion energy source of the mechanical motion device. At the same time, the external console is stopped from being used, and the external console is in a failure state and cannot control the mechanical motion device to release dangerous energy. The design of this safety system can effectively prevent the occurrence of mechanical injury accidents caused by accidentally closing the safety door and accidentally operating the buttons on the console without noticing that there are personnel operating inside the equipment, ensuring the life and health safety of the operators.
[0027] In an alternative embodiment, the safety button 6 is connected to the power supply module of the mechanical motion device 3, and the safety button 6 is used to control the power supply module to turn off when receiving the start signal.
[0028] Specifically, the safety button 6 is connected to the power supply module of the mechanical motion device 3.

[0033] In an alternative embodiment, the sensor 5 is respectively connected to the mechanical movement device 3 and the control console 4.
[0034] Specifically, when the operator finishes the operation and safely leaves the mechanical movement area, the safety button 6 receives the shutdown signal triggered by the user pressing the button and sends the shutdown signal to the sensor 5. The sensor 5 is respectively connected to the mechanical movement device 3 and the control console 4, and can restore the mechanical movement device 3 and the control console 4.
[0035] In an alternative embodiment, the sensor 5 is further configured to: when the safety door 2 is closed and the shutdown signal is received, control the mechanical movement device 3 to resume movement and the control console 4 to resume use.
[0036] Specifically, when the operator finishes the operation, the safety button 6 receives the shutdown signal triggered by the user pressing the button and sends the shutdown signal to the sensor 5. When the sensor 5 receives the shutdown signal and at the same time the staff member walks out of the device and closes the safety door, the sensor 5 recognizes the signal that the safety door is closed, and controls the mechanical movement device 3 to resume movement and the control console 4 to resume use.
[0037] In an alternative embodiment, the sensor 5 is connected to the power supply module of the mechanical movement device 3. The sensor 5 is configured to control the power supply module to turn on when the safety door 2 is closed and the shutdown signal is received.
[0038] Specifically, the sensor 5 is connected to the power supply module of the mechanical movement device 3. When the operator finishes the operation, the safety button 6 receives the shutdown signal triggered by the user pressing the button and sends the shutdown signal to the sensor 5. When the sensor 5 receives the shutdown signal and at the same time the staff member walks out of the device and closes the safety door, the sensor 5 recognizes that the safety door is closed and controls the power supply module of the mechanical movement device 3 to turn on, thereby resuming the operation of the mechanical movement device 3.
[0039] In an alternative embodiment, the sensor 5 is communicatively connected to the control console 4. The sensor 5 is configured to control the control console 4 to be in an enabled state when the safety door 2 is closed and the shutdown signal is received.

[0041] It can be seen that this application designs a safety system for preventing mechanical injuries in a solar energy device. A safety button is designed inside the device. When there are personnel operating, the safety door is opened, and the added safety button inside the device is automatically activated (to prevent the situation where personnel forget to press this button and it fails to play a protective role), automatically cutting off the mechanical injury energy source of the device. Through the design of this safety system, when personnel enter the device for operation, only when the internal operator finishes the operation and presses the internal button of the device personally, can the external console button normally operate the device. Otherwise, the external console is in a failure state and cannot release dangerous energy. The design of this safety system can effectively prevent the occurrence of mechanical injury accidents caused by accidentally closing the safety door and accidentally operating the buttons on the console without noticing that there are personnel operating inside the device, ensuring the life, health and safety of the operators.

[0046] This patent aims to form a linkage between the safety button inside the device and the safety door by adding a safety button inside the device, that is, when the safety door is opened, the safety button inside the device is automatically activated, automatically cutting off the mechanical injury energy source of the device. Through the design of this safety system, when personnel enter the device for operation, only when the internal operator finishes the operation and presses the internal button of the device personally, can the external console button normally operate the device. Otherwise, the external console is in a failure state and cannot release dangerous energy. The design of this safety system can effectively prevent the occurrence of mechanical injury accidents caused by accidentally closing the safety door and accidentally operating the buttons on the console without noticing that there are personnel operating inside the device, ensuring the life, health and safety of the operators.
