DETAILED DESCRIPTION

[0026] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present utility model. The protection scope of the present utility model is not limited to the description of the following embodiments.

[0027] Safety protection devices are usually installed at construction sites to prevent unauthorized personnel from entering the construction site and prevent safety problems. The safety protection devices usually include multiple support columns and protective plates installed between the support columns for blocking. Usually, in order to save materials, the protective plates adopt a mesh structure of the protective net, which can be ventilated and breathable while allowing the situation at the construction site to be clearly seen. In order to improve the protection level of the protective net, the protective net is generally made of metal materials, such as iron, aluminum, or various alloy materials.

[0028] For example, Figure 1a and Figure 1b A safety protection device is shown, such as Figure 1a As shown, the safety protection device includes a protection net structure 1, which is composed of multiple grids. The safety protection device also includes a monitoring system 2 for monitoring the environment around the protection net structure 1.

[0029] When someone mistakenly enters the monitoring range of the monitoring system 2, the system can react, warn and remind unrelated personnel to keep a certain safe distance from the construction site, and / or send prompt information to the management personnel. The safety protection device of this application can be used in electrical automation construction sites to shield and protect live equipment to prevent unrelated personnel from mistakenly entering the live interval and causing electric shock accidents.

[0030] The monitoring system 2 includes a safety protection controller 21, a sensor 22 and a terminal device for receiving instructions (not shown in the figure).

[0031] like Figure 1b and Figure 2 As shown, the safety protection controller 21 is a box structure, including a power module 23, a sensor 24, a control module (not shown) and an interface module 25.

[0032] The power module 23 is used to provide power for the safety protection controller 21. The power module 23 can be a battery or a wired power supply. The sensor 22 is connected to the sensor 24 to collect environmental information within a fixed area of ​​the protection net structure 1 and send the information to the sensor 24. Generally, the sensor 22 and the sensor 24 are wirelessly connected, which is more convenient to install. Of course, a wired connection can also be used, so that the transmitted data is more timely and accurate.

[0033] The sensor 24 is connected to the control module and is used to receive information sent by the sensor 22 and send the collected information to the control module;

[0034] The control module is connected to the interface module 25 and is connected to the terminal device through the interface module 25 . The control module obtains information received by the sensor 24 and sends instructions to the terminal device through the interface module 25 .

[0035] The protective net structure 1 in the safety protection device of this embodiment is composed of multiple grids, which are flexible and simple to install and easy to disassemble; the monitoring system 2 includes a safety protection controller 21, a sensor 22 and a terminal device for receiving instructions. The safety protection controller 21 is mainly used to receive the monitoring information sent by the sensor 22 and send control instructions to the terminal device. By setting up the monitoring system 2, the environment around the protective net structure 1 can be monitored, and it has a better perception of the environment. When someone mistakenly enters the monitoring range of the monitoring system, the system can respond quickly, warn and remind unrelated personnel to maintain a certain safe distance from the construction site, which can further improve the sensitivity and safety of the safety protection device.

[0036] Furthermore, the safety protection controller 21 includes a shell with a box structure, the control module is arranged in the shell, the power module 23, the sensor 24 and the interface module 25 are installed in or on the shell, and the safety protection controller 21 also includes an operation button 26 and a display screen 27 installed at the operating position of the shell. The operation button 26 and the display screen 27 are connected to the control module for regulating and setting the monitoring system 2.

[0037] Preferably, the safety protection controller 21 is integrally installed on one side of the protection net structure 1; the at least one sensor 22 is installed on the protection net structure 1, covering the installation area of ​​the protection net structure 1 to monitor the surrounding environment.

[0038] In one embodiment, the terminal device may be a buzzer alarm. When the sensor 22 detects an abnormal environment, the buzzer alarm will sound an alarm to prompt staff to check.

[0039] In another embodiment, the terminal device is a controllable switch, and the protective net structure 1 is used to surround the electrical equipment. The controllable switch is connected in series to the power supply circuit of the electrical equipment. The control module sends instructions to the controllable switch through the interface module 25 to disconnect the power supply to the electrical equipment and control the start and stop of the electrical equipment. This can improve the sensitivity of the safety protection device and quickly cut off the power supply to the electrical equipment when someone accidentally enters, preventing electric shock accidents. The controllable switch can be a contactor, relay, circuit breaker, or other switch.

[0040] In another embodiment, the terminal device is a computer, mobile phone, or other device. The computer can also be connected to an electrical device. The interface module 25 includes a wireless communication module. The control module sends instructions to the computer via the interface module 25. After receiving the instructions, the computer remotely controls the electrical device to stop and start. Alternatively, the control module sends notification information to the mobile phone via the interface module 25.

[0041] Preferably, Figure 1a As shown, the protective net structure 1 can also be installed with a protective door 5 for personnel to pass through, and at least one sensor 22 is installed on the protective door 5. The protective door 5 is preferably installed in the middle of the protective net structure 1. At least one sensor 22 can be installed on the protective door 5, which can maximize the coverage of the environment around the protective net structure 1. Of course, the protective door 5 can also be installed on one side of the protective net structure 1. This is all within the scope of protection of this application. By arranging the protective door 5 on the protective net structure 1, it is convenient for staff to enter and exit the construction site.

[0042] Preferably, the sensor 22 can be an infrared sensor, and the monitoring system 2 monitors the surrounding environmental information by infrared sensing. In other feasible methods, the sensor 22 can also be a door and window sensor, which is used to detect whether the doors and windows are open. When the door and window sensor detects that the protective door 5 or the window is opened, the sensor 24 receives the information sent by the door and window sensor, and then the control module of the security protection controller 21 sends an instruction to the terminal device through the interface module 25, and the terminal device will make an alarm indication.

[0043] Preferably, the sensor 22 is a tilt sensor (such as an SCL3300 tilt sensor) used to detect whether the protective net structure 1 is tilted. When the protective door 5 or the protective net structure 1 tilts at a certain angle or falls over, the sensor 24 receives the signal sent by the tilt sensor, and the control module sends an instruction to the terminal device through the interface module 25. The terminal device will issue a warning to remind the staff to check the situation.

[0044] Preferably, the connection between the grids is provided with a first mounting structure 3 and a second mounting structure 4, and the grids are fixedly connected by the cooperation of the first mounting structure 3 and the second mounting structure 4. The grids are detachable, spliced ​​and assembled, making the safety net structure 1 quick to install and more convenient to carry.

[0045] Further, such as Figure 3 As shown, the first mounting structure 3 is a slide groove structure, and the second mounting structure 4 is a boss structure. The boss structure is inserted into the slide groove structure from top to bottom along the height direction of the protective net structure 1 to facilitate installation and disassembly.

[0046] Furthermore, the slide groove structure is a groove opened on the side of the grid, and the boss structure can be the side of the grid. In this way, there is no need to separately protrude the groove structure and boss structure on the side of the grid, which saves production costs and has a simple and beautiful structure.

[0047] Preferably, Figure 3 and Figure 4 As shown, a first limiting structure 6 is provided at one end opening of the first mounting structure 3, and the first limiting structure 6 limits the second mounting structure 4 in the height direction of the protective net structure 1. The provision of the first limiting structure 6 makes the installation of the grids more firm and reliable.

[0048] Furthermore, the first limiting structure 6 includes an elastic component 61 and a limiting portion 62. One end of the elastic component 61 is connected to the first mounting structure 3, and the other end is connected to the limiting portion 62, blocking one end of the groove structure. The upper surface of the limiting portion 62 is a sloped structure. The limiting portion 62 reciprocates along the splicing direction of the protective net structure 1. When the grids are spliced ​​together, one end of the boss structure is against the sloped structure of the limiting portion 62, and pressure is applied from top to bottom, driving the limiting portion 62 to compress the elastic component 61 to avoid the boss structure, so that the boss structure can extend into the slide groove structure to achieve the installation and fixation of the grids. Among them, the elastic component 61 can be a compression spring, a spring or other elastic member. The design of the sloped structure of the limiting portion 62 allows the limiting portion 62 to move along the grid splicing direction to compress the elastic component 61 and avoid the boss structure when the limiting portion 62 is pressed from top to bottom.

[0049] Further, such as Figure 3 As shown, support columns 11 are provided at both ends of the protective net structure 1 in the splicing direction. The support columns 11 are perpendicular to the ground and are used to install and fix the protective net structure 1. Of course, in feasible embodiments, support columns 11 can be provided at the connection between the grids of the protective net structure 1, or the protective net structure 1 can also be provided without support columns. The grids that make up the protective net structure 1 can be directly installed and fixed in close contact with the ground. All of these fall within the scope of protection of this application.

[0050] Furthermore, the grid includes a frame and a metal mesh, and the support column 11 is an extension of one side of the frame. In this way, there is no need to set up a separate support column 11, which can save time for installing the protective net structure 1 and improve installation efficiency.

[0051] The safety protection device provided in the present application is configured to block irrelevant personnel from entering and exiting the construction site by setting up a protection net structure 1, and to set up a monitoring system 2 near the protection net structure 1 for monitoring the surrounding environment of the protection net structure 1. The surrounding environment of the protection net structure 1 is monitored in real time by the monitoring system 2. When someone approaches the construction site, the monitoring system 2 can respond quickly, sound an alarm, and / or immediately cut off the power supply to the electrical equipment to prevent safety problems or damage to the electrical equipment. The utility model can improve the sensitivity and safety of the safety protection device through the cooperation of the protection net structure 1 and the monitoring system 2. At the same time, the intelligent monitoring system also saves manual monitoring costs.

[0052] Finally, a preferred embodiment of a safety protection device is provided. The protective net structure 1 is composed of multiple meshes and is also equipped with a protective door 5. At least two sensors 22 are installed on the meshes of the protective net structure 1, at least one of which is an infrared sensor and at least one is a tilt sensor. At least two sensors 22 are installed on the protective door 5, at least one of which is an infrared sensor and at least one is a door and window sensor.

The protective net structure 1 surrounds at least one electrical device, and the terminal device includes a controllable switch connected in series to the power supply circuit of the electrical device. The interface module 25 includes a wireless communication module for sending notification information to a mobile phone.

[0053] The safety protection device of this embodiment can alarm through a buzzer alarm or send a notification prompt message to a mobile phone through a wireless communication module when the protection net structure 1 tilts; it can alarm through a buzzer alarm when an unrelated person approaches; when an unrelated person opens the protection door 5, it can shut down the electrical equipment through a controllable switch, and / or alarm through a buzzer alarm, and send a notification prompt message to a mobile phone through a wireless communication module.
