DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1-4 The power analysis device for microgrid energy management shown in the figure includes a protective box 1 and a power analyzer body 2 located in the middle of the protective box 1. A display screen 4 and a connecting column 5 are arranged on the top of the power analyzer body 2. The power analyzer body 2 is connected to the power supply wire of the device to be detected through the connecting column 5, and the power detection can be performed, and the detection value is displayed on the display screen 4, which is convenient for detection and use. The top of the protective box 1 is rotatably connected with a sealing cover 3, and the power analyzer body 2 is covered and protected by the protective box 1 and the sealing cover 3, which is convenient for carrying and protection. An extrusion rod 20 is fixedly connected to the middle of the inner cavity of the sealing cover 3, and a heat dissipation mechanism is arranged at the bottom of the power analyzer body 2. The extrusion rod 20 can be used to twist and squeeze the power analyzer body 2 when the sealing cover 3 is closed, thereby improving the stability of the power analyzer body 2, and the heat dissipation mechanism is convenient for the power analyzer body 2 to dissipate heat, thereby improving the use effect;

[0025] The bottom and side of the electric quantity analyzer body 2 are provided with a buffer mechanism, which includes a fixed block 12 fixed on the surface of the electric quantity analyzer body 2, a memory spring plate 13 is fixedly connected to the middle of the fixed block 12, one end of the memory spring plate 13 is fixedly connected to a support block 14, and a rolling ball 15 is provided on one side of the support block 14. Through the buffer mechanism, the electric quantity analyzer body 2 can drive the fixed block 12 to squeeze the memory spring plate 13, so that the memory spring plate 13 is deformed, thereby achieving buffer protection for the electric quantity analyzer body 2, avoiding damage to the electric quantity analyzer body 2 due to external collision, and playing a protective role;

[0026] A limiting plate 16 is fixedly connected to the top of the four sides of the electrical quantity analyzer body 2, a positioning hole 17 is opened in the middle of the limiting plate 16, a limiting groove 19 is opened at a position corresponding to the limiting plate 16 in the inner cavity of the protective box 1, and a positioning rod 18 is fixedly connected to a position corresponding to the positioning hole 17 at the top of the inner cavity of the protective box 1. The electrical quantity analyzer body 2 is limited in the middle of the protective box 1 by the limiting plate 16, and the limiting groove 19 can not affect the up and down and horizontal shaking of the electrical quantity analyzer body 2, and the positioning rod 18 is inserted into the inside of the positioning hole 17, so that the electrical quantity analyzer body 2 can be stably limited when the sealing cover 3 is opened, which is convenient for connecting and using from the side.

[0027] As attached Figure 1 , 2 As shown, a lock buckle 21 is fixedly connected to one side of the sealing cover 3, and a handle 22 is fixedly connected to one side of the protective box body 1. The lock buckle 21 is used to conveniently fix the closed sealing cover 3, and the handle 22 is used to facilitate hand-carrying.

[0028] As attached Figure 2-4 As shown, two memory spring plates 13 are fixedly connected to the middle part of the fixed block 12, and the two memory spring plates 13 are perpendicular to each other. The rolling ball 15 fits against the wall of the protective box 1. The rolling ball 15 avoids friction between the support block 14 and the wall of the protective box 1, thereby improving the smoothness of the shaking of the electrical quantity analyzer body 2, and improving the buffering effect through the memory spring plate 13.

[0029] As attached Figure 2 As shown, the heat dissipation mechanism includes a groove 6 opened at the bottom of the electrical quantity analyzer body 2, a heat conducting plate 7 is fixedly connected to the top of the inner cavity of the groove 6, a heat dissipation plate 8 is fixedly connected to the bottom of the heat conducting plate 7, and a heat dissipation fan 9 is arranged at the opening of the groove 6. When the heat dissipation fan 9 is started, the heat on the surface of the heat conducting plate 7 and the heat dissipation plate 8 can be blown away to achieve the effect of cooling and heat dissipation.

[0030] As attached Figure 2As shown, a porous plate 11 is provided at the bottom of the protective box 1, and a filter plate 10 is provided on the top of the porous plate 11. The filter plate 10 corresponds to the groove 6. The hot air inside the protective box 1 can be discharged through the porous plate 11, and the filter plate 10 can prevent external dust from entering the interior of the protective box 1, thereby improving the use effect.

[0031] As attached Figure 2 , 3 As shown, the extrusion rod 20 is offset from the connecting column 5 and the display screen 4, and one end of the limit plate 16 extends to the inside of the limit groove 19. The extrusion rod 20 pushes the electrical quantity analyzer body 2, so that the closing of the sealing cover 3 can separate the positioning rod 18 from the positioning hole 17, thereby providing protection and buffering for the internal electrical quantity analyzer body 2 when the protective box 1 is hit.

[0032] As attached Figure 2 , 3 As shown, the number of the insertion rods 18 is the same as the number of the positioning holes 17, and one end of the insertion rod 18 extends into the interior of the positioning hole 17. Through the cooperation of the positioning hole 17 and the insertion rod 18, the electrical quantity analyzer body 2 can be fixed for use, thereby improving the use effect.

[0033] Working principle of the utility model: when in use, it is only necessary to open the sealing cover 3. At this time, the memory spring plate 13 pushes the power analyzer body 2, so that the positioning rod 18 can be inserted into the positioning hole 17 to stabilize the power analyzer body 2, and then the wires of the external device are connected to the connecting column 5. The power analyzer body 2 can be used to detect and analyze the power and display it on the surface of the display screen 4;

[0034] When the power analyzer body 2 needs to be cooled, the cooling fan 9 is started to transfer the heat generated in the middle of the power analyzer body 2 to the heat dissipation plate 8 through the heat conduction plate 7. The heat dissipation plate 8 and the cooling fan 9 discharge the heat to achieve the function of heat dissipation, thereby extending the service life of the power analyzer body 2;

[0035] When the device is not in use, the sealing cover 3 is closed. At this time, the positioning rod 18 is separated from the positioning hole 17 by pushing the electric quantity analyzer body 2 by the squeezing rod 20. The filter plate 10 can prevent external dust from entering the interior of the protective box 1, thereby playing a protective filtering role.

[0036] When the outside of the protective box 1 is hit or shaken, the memory spring plate 13 will be pressurized through the support block 14 and the fixed block 12, causing the memory spring plate 13 to deform. The reverse force of the memory spring plate 13 can buffer and protect the power analyzer body 2, thereby avoiding damage to the power analyzer body 2 and improving the use effect.
