Description

Technical Field

[0001] The utility model relates to the technical field of monitoring, in particular to a monitoring device capable of multi-screen display. Background Art

[0002] Coal mining is a complex production process with great safety hazards. Abnormal production environment or equipment failure may cause huge losses. Therefore, monitoring is installed in various production links and locations of coal mines to monitor the entire coal mine production process in real time, promptly discover safety hazards in production, and provide important basis for decision-making.

[0003] At present, since there are many production links and places that need to be monitored in coal mines, multiple screens are needed to display various monitoring information in real time. However, due to the large number of monitoring screens, when the staff watch the monitoring screens, the monitoring screens located on both sides of the staff have a small angle with the staff's line of sight, which makes it inconvenient for the staff to watch the monitoring screens on both sides, and it is easy to see the information on the monitoring screens clearly. For this reason, we propose a monitoring device that can display multiple screens. Utility Model Content

[0004] The utility model aims to provide a monitoring device capable of multi-screen display. When the multi-screen is used to display coal mine monitoring information, the monitoring screens at both sides can be adjusted in angle to increase the angle between the staff's line of sight and the monitoring screens at both sides, so that the staff can see the information on the monitoring screens clearly. This solves the problem that there are many production links and places to be monitored in coal mines, so multiple screens are needed to display various monitoring information in real time. However, due to the large number of monitoring screens, when the staff views the monitoring screens, the monitoring screens located on both sides of the staff have a smaller angle with the staff's line of sight, which makes it inconvenient for the staff to view the monitoring screens on both sides and it is easy to not see the information on the monitoring screens clearly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a monitoring device capable of multi-screen display, comprising a fixing frame and a monitoring screen, the front surface of the fixing frame being provided with a plurality of mounting openings equidistantly spaced in a rectangular array, a monitoring screen being provided inside each of the mounting openings, a plurality of mounting plates being equidistantly fixedly installed in a rectangular array on the inner wall of the fixing frame near the rear surface, and the mounting plates and the mounting openings corresponding one to one, a first electric push rod being fixedly connected to one side of the front surface of each mounting plate, a second electric push rod being rotatably installed on the side of the front surface of each mounting plate facing away from the first electric push rod, and the ends of the first electric push rod and the second electric push rod being rotatably connected to the positions on both sides of the rear surface of each monitoring screen.

[0006] Preferably, ventilation holes are symmetrically arranged at both sides of the outer surface of the fixing frame.

[0007] Preferably, a dust filter is fixedly installed inside each of the vents.

[0008] Preferably, a plurality of cooling fans are fixedly installed at equal distances inside the fixing frame near the two ventilation openings.

[0009] Preferably, a temperature sensor and a timing switch are fixedly mounted on the top of the inner wall of the fixing frame, and both the temperature sensor and the timing switch are electrically connected to the cooling fan.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model achieves the effect of adjusting the angles of the monitoring screens at both sides when using multiple screens to display coal mine monitoring information by arranging a fixing frame, a monitoring screen, a mounting port, a mounting plate, a first electric push rod and a second electric push rod, so that the angles of the monitoring screens at both sides can be adjusted, so that the angle between the staff's line of sight and the monitoring screens at both sides is increased, so that the staff can clearly see the information on the monitoring screens. The fixing frame is fixed at a designated position such as a wall, and the monitoring screen is used to display coal mine production monitoring information. When the staff views the monitoring screens at both sides, the first electric push rod drives the monitoring screen to move from the mounting port to the outside, and the second electric push rod drives the monitoring screen to rotate, so that the staff can directly see the monitoring screens at both sides, thereby increasing the angle between the staff's line of sight and the monitoring screens at both sides, so that the staff can clearly view the information on the monitoring screens at both sides.

[0012] 2. The utility model achieves the effect of automatically ventilating and cooling the interior of the fixed frame by arranging vents, cooling fans and temperature sensors. The temperature inside the fixed frame is monitored by the temperature sensor. When the temperature inside the fixed frame rises to a set value, the cooling fan starts to discharge the hot air inside the fixed frame from the vents, while the cold air from the outside enters the interior of the fixed frame from the vents, automatically ventilating and cooling the monitoring screen.

[0013] 3. The utility model achieves the effect of preventing external dust from entering the interior of the fixing frame from the vents and preventing the dust filter from being blocked by the dust filter through the dust filter. When the external air enters the interior of the fixing frame from the vents, the dust impurities therein are filtered out by the dust filter, and the timing switch controls the cooling fans on both sides of the interior of the fixing frame at a fixed time, so that the two vents alternately take in and out air, thereby being able to blow away the dust impurities adhered to the outer surface of the dust filter and avoid its blockage.
