However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0021] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1-4 As shown, a power transmission and transformation system equipment status simulation device includes a simulation device body 6, with multiple heat dissipation holes 12 opened on the left side of the simulation device body 6; a ventilation mechanism, which is installed on the left side of the simulation device body 6; and a blowing mechanism, which is installed on the left side of the ventilation mechanism.

[0024] The ventilation mechanism includes: a support plate 8; a slide groove 27, a slide groove 27 is vertically opened on one side of the support plate 8; a cover plate 10, a plurality of cover plates 10 are arranged on one side of the support plate 8 along the length direction of the slide groove 27, and sliders 9 are fixed on both the upper and lower sides of the cover plate 10, and the sliders 9 are slidably connected to the slide groove 27; a ventilation pipe 16, a plurality of ventilation pipes 16 are fixedly provided on the support plate 8, the ventilation pipe 16 is located in the cover plate 10, and a trumpet-shaped air guide cover 15 is fixed on one end of the ventilation pipe 16 close to the cover plate 10; a second ventilation pipe 26, a second ventilation pipe 26 is fixedly provided in the center of the cover plate 10 6; a first connecting rod 23, a first connecting rod 23 is fixedly provided at both upper and lower ends of the support plate 8; a second connecting rod 22, the first connecting rod 23 is connected to the second connecting rod 22 through a first torsion spring 25; a plug-in plate 20, the second connecting rod 22 is connected to the plug-in plate 20 through a second torsion spring 21; a U-shaped limiting plate 19, the U-shaped limiting plate 19 is fixedly connected to the simulation device body 6, and the plug-in plate 20 is slidably inserted in the U-shaped limiting plate 19; a limiting screw 18, the limiting screw 18 is threadedly connected to the U-shaped limiting plate 19; a knob 17, the knob 17 is fixedly connected to the limiting screw 18.

[0025] The blowing mechanism includes: a protective cover 1, which is made of stainless steel and is fixed to the left side of the support plate 8; a motor 2, which is fixed to the left side of the protective cover 1; a bearing 3, which is installed on the left side of the protective cover 1 and is sleeved on the power output end 7 of the motor 2; and fan blades 4, which are provided in the protective cover 1 with a plurality of fan blades 4, which are fixed to the power output shaft 7.

[0026] Working principle: When in use, move the cover plate 10 up and down along the slide groove 27 so that the second ventilation pipe 26 is aligned with the heat dissipation hole 12 on the simulation device body, and then push the support plate 8 toward the direction of the simulation device body 6 to insert the second ventilation pipe 26 into the heat dissipation hole 12, so that the second ventilation pipe 26 extends into the simulation device body 6.

[0027] Start the motor 2, so that the power output shaft 7 of the motor 2 drives the fan blades 4 to rotate. The wind blown out by the fan blades 4 enters the cover plate 10 through the ventilation pipe 16, then enters the second ventilation pipe 16, and then enters the simulation device body 6 to dissipate heat inside the simulation device body.

[0028] When moving the support plate 8, it is necessary to first remove the limit screw 18, and then move the support plate 8. Since the first connecting rod 23 is fixed at the upper and lower ends of the support plate 8, the first connecting rod 23 is connected to the second connecting rod 22 through the first torsion spring 25, and the second connecting rod 22 is connected to the plug plate 20 through the second torsion spring 21, so that when the support plate 8 is pushed toward the direction of the simulation device body 6, the plug plate 20 slides in the U-shaped limit plate 19. After the position of the support plate 8 is adjusted, the limit screw 18 is reconnected to the U-shaped limit plate 19 so that the limit screw 18 is pressed against the plug plate 20, thereby fixing the position of the plug plate 20, and then fixing the position of the support plate 8.

[0029] Example 2

[0030] like Figure 1-4 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that the ventilation mechanism also includes a locking assembly, which includes: two arc-shaped spring plates 11, and arc-shaped spring plates 11 are fixed on both the upper and lower sides of the right end of the second ventilation pipe 26; an auxiliary ventilation pipe 13, and a plurality of auxiliary ventilation pipes 13 are fixed on the right end of the second ventilation pipe 26 along the circumference of the second ventilation pipe 26.

[0031] Working principle: When the second ventilation tube 26 is inserted into the heat dissipation hole 12, the two arc-shaped spring plates 11 approach each other, so that the second ventilation tube 26 can be smoothly inserted into the simulation device body 6. After insertion, the two arc-shaped spring plates 11 that were originally close to each other move away from each other, so that the second ventilation tube 26 cannot be easily pulled out from the simulation device body 6.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
