[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] In order to enable those skilled in the art to better understand the present invention, 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 described embodiments are only part of the embodiments of the present invention, not all of them. The drawings show preferred embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] Unless otherwise specified, various raw materials, instruments and equipment used in the present invention can be purchased from the market or prepared by existing methods.

[0030] Figure 1 This is a schematic diagram of the appearance structure of the ventilated explosion-proof instrument box of the utility model. Figure 2 This is a schematic diagram of the internal structure principle of the ventilated explosion-proof instrument box of the utility model. Figure 3 This is a schematic diagram of the electrical connection principle of the ventilation explosion-proof instrument box of the utility model, refer to Figure 1-3 As shown, the ventilated explosion-proof instrument box includes a hollow box body 1, and a controller 7, an alarm 8 and a numerical control instrument assembly 12 respectively arranged in the box body 1, and the alarm 8 and the numerical control instrument assembly 12 are respectively electrically connected to the controller 7;

[0031] The top and bottom of the box body 1 are respectively connected with at least one exhaust port 4 and at least one air inlet 5, and the exhaust port 4 and the air inlet 5 are respectively used to communicate with the inside of the box body 1 to realize air circulation and achieve ventilation and explosion-proof effects.

[0032] In the embodiment of the present utility model, combined with Figure 4 As shown, Figure 4The reference diagram is a schematic diagram of the positions of the exhaust port and the air inlet in the box, wherein the exhaust port 4 and the air inlet 5 are respectively located at two ends of a diagonal position in the box 1. For example, the air inlet 5 is located at the bottom of the box 1 near the door axis, and the exhaust port 4 is located at the other end angle of the top of the box 1 that is symmetrical to the air inlet 5 along the central axis, thereby making the range of gas convection in the box 1 larger and effectively reducing the concentration of hazardous gases in the box 1.

[0033] An exhaust pipe 9 is extended at the outlet of the exhaust port 4, and an exhaust fan 10 is arranged in the exhaust pipe 9. The exhaust fan 10 is electrically connected to the controller 7 through a relay switch component 13. When there is a safety risk in the box 1 and the alarm 8 sounds, the controller 7 can control the exhaust fan 10 to turn on accordingly, so as to quickly discharge the gas in the box 1 through the exhaust pipe 9 to avoid the occurrence of combustion and explosion accidents.

[0034] The top of the exhaust pipe 9 is provided with a rainproof cap, which can effectively block rainwater and prevent the normal operation of the exhaust fan 10 from being affected.

[0035] The entrance of the air inlet 5 is covered with a dustproof net 11 to provide a certain protection effect and prevent external debris from entering the box body 1 through the air inlet 5 and interfering with the operating status of various components inside the box body 1.

[0036] The CNC instrument assembly 12 is used to perform corresponding functional tests, and the alarm 8 is used to monitor the gas (i.e., dangerous gas, such as coal gas, hydrogen, etc.) in the box 1. When it is identified that the corresponding gas concentration reaches a threshold, the alarm is automatically triggered and a signal is sent to the controller 7. The controller 7 controls the exhaust fan 10 to turn on, thereby discharging the internal gas to reduce the concentration and avoid combustion and explosion problems.

[0037] The alarm 8 may be one or more of gas alarms such as a carbon monoxide alarm 8, a hydrogen alarm 8, an oxygen alarm 8, a methane alarm 8, etc., depending on the use environment.

[0038] The alarm 8 is a gas alarm with sound and light alarm functions, so that the staff can be reminded by flashing lights or sounding alarms.

[0039] The alarm 8, controller 7 and exhaust fan 10 are all explosion-proof devices.

[0040] In the example of the utility model, each active device inside the box 1 can be powered by an external power supply to achieve normal operation. In some embodiments, the box 1 can also be provided with a power module 6, and the power module 6 is electrically connected to the controller 7 to provide power support for each active device inside the box 1. The power module 6 can be a safe power supply or a combination of a solar panel and a battery. The solar panel is arranged outside the box 1, and the battery is arranged inside the box 1. The solar panel converts electrical energy through solar energy and sends it to the battery for storage.

[0041] In the embodiment of the utility model, the box body 1 is provided with an openable door 2. When the box door 2 is used for maintenance, it can be opened to disassemble or replace the internal components. At the same time, it can also be opened in some scenarios to increase the circulation of internal and external air. The opening position of the box door 2 can be selected according to actual application requirements. For example, in this embodiment, the box door 2 is opened on the side of the box body 1. In other embodiments, it can also be considered to be opened on the top of the box body 1 after leak-proof treatment.

[0042] An observation hole 3 is provided on the box door 2 for technicians to observe the operating status inside the box body 1. In some embodiments of the utility model, the observation hole 3 can also be covered with a light-transmitting plate (such as a glass layer, etc.) to provide a protective effect to prevent external debris from entering the box body 1 through the observation hole 3 and interfering with the operating status of various components inside the box body 1.

[0043] Of course, it should be noted that, in some embodiments, the ventilation explosion-proof instrument box can also be connected to a cloud server via a wireless network to achieve a remote control function, which can be selected according to the actual application scenario requirements.

[0044] Compared with the prior art, the ventilated explosion-proof instrument box described in the embodiment of the utility model has the following advantages:

[0045] 1. The gas concentration inside the box 1 is monitored by the alarm 8, and an alarm is automatically triggered when the corresponding gas concentration reaches a threshold value. The exhaust fan 10 is controlled to open by the controller 7 accordingly, so as to discharge the internal gas to reduce the concentration and avoid the problem of explosion;

[0046] 2. The air inlet is located at the door end, and the exhaust hole is located at a symmetrical position on the central axis, which can ensure full circulation of gas in the box and provide better replacement effect. At the same time, the air inlet is located at the door end, which can effectively reduce the concentration of toxic and harmful gases at the door and prevent maintenance personnel from contacting toxic and harmful gases and causing accidents;

[0047] 3. Solar panels can be used to provide energy for the alarm 8 and the exhaust fan 10, which reduces energy consumption and has a good environmental protection effect.
