Technical Field

[0001] The utility model relates to the technical field of LED electronic screens, in particular to an array type LED electronic screen. Background Art

[0002] An LED electronic display screen is a display mode that controls semiconductor light-emitting diodes and is composed of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixel points arranged evenly. It can use different materials to manufacture LED pixel points of different colors to display various information such as text, graphics, images, animations, market conditions, videos, and video signals.

[0003] Currently, many large stages and promotional advertisements use multiple LED electronic screens for assembly. The assembly structure is complex, and when the LED electronic screens are assembled, heat is likely to accumulate around them, making it difficult to dissipate heat. When the LED electronic screens cause smoke or open fire due to overheating, it is difficult to carry out effective protection and treatment in a timely manner.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0029] Please refer to Figures 1 to 4 , an array-type LED electronic screen provided by an embodiment of the present utility model, the array-type LED electronic screen includes: an electronic screen unit 1, an installation cylinder 2, and a storage tube 7.

[0030] In an embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the array-type LED electronic screen is formed by arranging a plurality of electronic screen units 1 with the same specifications in a square matrix, and the electronic screen unit 1 includes a monomer mounting frame 11, a monomer LED display screen 12 is fixedly embedded on the front end face of the monomer mounting frame 11, a smoke sensor is embedded on the monomer mounting frame 11, and arc cavities 13 are opened at the four corners of the monomer mounting frame 11. Arc grooves 14 are opened on the monomer mounting frame 11 on both sides of the arc cavity 13, and a threaded fixing groove 15 is opened in the middle of the arc groove 14. The arc cavities 13 on the electronic screen units 1 arranged in a square matrix are combined into a cylindrical cavity;

[0031] Adjacent electronic screen units 1 are connected by an installation cylinder 2. Pressing rings 3 are fixedly installed on both sides of the installation cylinder 2. The installation cylinder 2 is inserted into the cylindrical cavity, and the pressing rings 3 on the installation cylinder 2 are embedded into the arc grooves 14 opened on the monomer mounting frame 11. A fixing screw is inserted into the fixing hole 3a opened on the pressing ring 3, and the fixing screw is inserted into the threaded fixing groove 15 in a rotationally tightened manner.

[0032] It should be noted that the array - type LED electronic screen is formed by arranging and combining several electronic screen units 1 with the same specifications in a square matrix and assembled and connected by installation cylinders 2. Each electronic screen unit 1 is independent. When a single electronic screen unit 1 is damaged, the damaged electronic screen unit 1 can be immediately removed after removing the fixing screws, and then a new electronic screen unit 1 can be replaced, which is simple and convenient.

[0033] In the embodiment of the present utility model, please refer to Figure 1 , Figure 3 and Figure 4 , several annularly - distributed storage tubes 7 are arranged in the installation cylinder 2. A sufficient amount of heptafluoropropane fire - extinguishing gas is stored in the storage tubes 7. An electromagnetic valve 8 is fixedly installed at the position of the storage tube 7 facing the cylinder mouth. A fan 4 is fixedly installed in the installation cylinder 2, and the fan 4 is located in the installation cylinder 2 above the storage tube 7. A plurality of annularly - distributed air - guiding holes 2a are opened on the cylinder wall of the installation cylinder 2 near the cylinder mouth. Among them, a wind - blocking disc 5 is fixedly fitted at the cylinder mouth of the installation cylinder 2. A plurality of annularly - distributed waist - shaped holes 5a are opened at the edge of the wind - blocking disc 5. A through - cavity is opened at the center of the wind - blocking disc 5, and a transparent sheet 6 is fixedly fitted in the through - cavity.

[0034] It should be noted that when the array - type LED electronic screen is in use, the fan 4 is turned on, and the heat dissipated by the single - piece batteries 3 on both sides around is absorbed through the air - guiding holes 2a on the installation cylinder 2 and discharged outside the rear cylinder mouth of the installation cylinder 2, thereby effectively reducing the heat around the single - body LED display screen 12 in each electronic screen unit 1 and effectively protecting the single - body LED display screen 12.

[0035] When the smoke sensor detects smoke, the motor drives the fan 4 to rotate in the reverse direction and at the same time opens the electromagnetic valve 8 on the storage tube 7. Thus, the heptafluoropropane in the storage tube 7 is dissipated to the periphery of the single - body LED display screens 12 on both sides through the air - guiding holes 2a on the installation cylinder 2 and the waist - shaped holes 5a on the wind - blocking disc 5, thereby avoiding the harm caused by open fire on the single - body LED display screens 12 and enhancing the safety of using the array - type LED electronic screen.

[0036] The working principle of the array - type LED electronic screen provided by the present utility model is as follows:

[0037] The array - type LED electronic screen is formed by arranging and combining several electronic screen units 1 with the same specifications in a square matrix and assembled and connected by installation cylinders 2. Each electronic screen unit 1 is independent. When a single electronic screen unit 1 is damaged, the damaged electronic screen unit 1 can be immediately removed after removing the fixing screws, and then a new electronic screen unit 1 can be replaced, which is simple and convenient.

[0038] When the array - type LED electronic screen is in use, the fan 4 is turned on to absorb the heat dissipated by the single - cell batteries 3 on both sides around through the air - guiding holes 2a on the mounting cylinder 2, and the heat is discharged outside from the rear barrel opening of the mounting cylinder 2, thereby effectively reducing the heat around the single - cell LED display screen 12 in each electronic - screen unit 1 and effectively protecting the single - cell LED display screen 12. When the smoke sensor detects smoke, the motor drives the fan 4 to reverse and at the same time opens the solenoid valve 8 on the storage pipe 7, so that the heptafluoropropane in the storage pipe 7 is dissipated to the periphery of the single - cell LED display screens 12 on both sides through the air - guiding holes 2a on the mounting cylinder 2 and the waist - shaped holes 5a on the wind - blocking disc 5, thereby avoiding the harm caused by open fire on the single - cell LED display screen 12 and enhancing the safety of the array - type LED electronic screen during use.
