DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 The utility model is described in further detail.

[0022] The utility model embodiment discloses an assembly structure of a power quality monitoring device, referring to Figure 1-2, including a power quality monitoring body 1, a U-shaped plate 2 provided at the bottom of the power quality monitoring body 1, a connecting mechanism installed on both sides of the U-shaped plate 2 and used to fix the power quality monitoring body 1, and a shock-absorbing mechanism installed at the bottom of the U-shaped plate 2 and used to reduce the vibration of the power quality monitoring body 1. The power quality monitoring body 1 is an existing power quality monitoring device, and its internal structure and principle have been disclosed, so no further details will be given here. The U-shaped plate 2 can support the power quality monitoring body 1.

[0023] Reference Figure 1-2 Two groups of heat sinks 21 are fixed on both sides of the U-shaped plate 2 for limiting the bottom of the power quality monitoring body 1 and dissipating heat. The power quality monitoring body 1 is fitted and abutted between the two groups of heat sinks 21. The two groups of heat sinks 21 can limit the bottom of the power quality monitoring body 1 so that the power quality monitoring body 1 will not move horizontally left and right. The two groups of heat sinks 21 can dissipate heat for the shell of the power quality monitoring body 1, thereby dissipating heat for the components installed on the shell of the power quality monitoring body 1. Heat dissipation helps to extend the service life of the power quality monitoring body 1.

[0024] Reference Figure 1-2 The connecting mechanism includes a first spring 3 fixed on both sides of the inner wall of the U-shaped plate 2, a pressure plate 31 fixed at one end of the first spring 3, and a plurality of fixed blocks 32 fixed at one end of the pressure plate 31. The fixed blocks 32 are inserted into the fixing holes opened on both sides of the power quality monitoring body 1. A pull rod 33 is fixed on the side of the pressure plate 31 close to the first spring 3, which passes through and extends to the outside of the U-shaped plate 2. The pressure plate 31 can connect the first spring 3 and the fixed block 32. The pull rod 33 can be T-shaped. The pull rod 33 can limit the pressure plate 31 and other components so that the pressure plate 31 and other components can move laterally.

[0025] Under the elastic force of the first spring 3, the fixing block 32 will be inserted into the fixing hole on the outer wall of the power quality monitoring body 1 to connect and assemble the power quality monitoring body 1. When people need to remove the assembled power quality monitoring body 1 for inspection and maintenance, people can hold the pull rod 33 and pull it to the outside of the U-shaped plate 2. The fixing block 32 will be disengaged from the fixing hole on the outer wall of the power quality monitoring body 1, thereby disengaging the power quality monitoring body 1. At this time, people can remove the power quality monitoring body 1 from the U-shaped plate 2.

[0026] Reference Figure 1-2A shock absorber is provided at the bottom edge of the U-shaped plate 2. The shock absorber includes two groups of second springs 4 and two groups of damping rods 42 fixed at the bottom edge of the U-shaped plate 2. The damping rods 42 are located inside the second springs 4. A bottom plate 41 is fixed between the bottom ends of the two groups of second springs 4 and the two groups of damping rods 42. A plurality of bolts are movably provided at the edge of the bottom plate 41. The damping of the damping rods 42 cooperates with the buffering of the second springs 4 to reduce the vibration of the U-shaped plate 2 and the power quality monitoring body 1 on the bottom plate 41, and the bottom plate 41 can be fixedly installed on the electrical equipment to be monitored by bolts.

[0027] Reference Figure 1-3 The shock absorbing mechanism includes two vertical plates 5 provided on the outside of the U-shaped plate 2, a third spring 52 fixed on one side of the vertical plate 5, and a slide 53 fixed at one end of the third spring 52. Two inclined connecting rods 54 are rotatably connected between the top of the two slides 53 and the center of the bottom surface of the U-shaped plate 2. An outer protective tube 55 and an inner sleeve 56 are fixed on the side of the two slides 53 away from the third spring 52. One end of the inner sleeve 56 is slidably connected to the outer protective tube 55. An air guide tube 57 for applying damping by suction and exhaust is fixed in the inner sleeve 56. The two connecting rods 54, the outer protective tube 55 and the inner sleeve 56 are distributed in a triangular shape.

[0028] When the U-shaped plate 2 is vibrated, it will be pressed down, thereby pressing the slide plate 53 toward the third spring 52 side through the inclined connecting rod 54, causing the third spring 52 to be compressed. At this time, the internal space of the outer casing 55 and the inner sleeve 56 will become larger, so that air is sucked in by the air guide pipe 57. When the third spring 52 rebounds, the two slide plates 53 will move closer to each other, causing the internal space of the outer casing 55 and the inner sleeve 56 to become smaller, so that air is exhausted by the air guide pipe 57. Since the diameter of the air guide pipe 57 is small, while the diameter of the outer casing 55 and the inner sleeve 56 is large, the air entering and exiting through the air guide pipe 57 during intake and exhaust will apply a certain damping to the movement of the outer casing 55 and the inner sleeve 56, similar to the resistance and damping encountered when people squeeze or stretch an air pump. Combined with the buffering of the third spring 52, the U-shaped plate 2 and the power quality monitoring body 1 can be shock-absorbing.

[0029] Reference Figure 1-3 The two vertical plates 5 are fixed at the bottom of the bottom plate 41, a cross bar 51 is fixed between the two vertical plates 5, and the slide plate 53 is slidably connected to the outside of the cross bar 51. The bottom plate 41 can support and fix the vertical plates 5, and the cross bar 51 can connect the two vertical plates 5. The cross bar 51 can also support and limit the slide plate 53, thereby improving the stability of the shock absorbing mechanism during operation.

[0030] Reference Figure 1-2The top of the air guide tube 57 is fixed in the U-shaped plate 2, and the top of the air guide tube 57 faces the heat sink 21. The air guide tube 57 can be a hose. When the outer protective tube 55 and the inner sleeve 56 move, they will inhale and exhaust air through the top of the air guide tube 57, thereby accelerating the air flow around the heat sink 21, which is helpful for the heat dissipation of the power quality monitoring body 1.

[0031] The implementation principle of the assembly structure of a power quality monitoring device according to an embodiment of the utility model is as follows:

[0032] During assembly, people can first use bolts to install the bottom plate 41 on the required electrical equipment, then people can pull the pull rods 33 on both sides of the U-shaped plate 2 toward the outside of the U-shaped plate 2, and place the power quality monitoring body 1 between two adjacent groups of heat sinks 21, and then release the pull rods 33. At this time, under the elastic force of the first spring 3, in conjunction with the connection of the pressure plate 31, the fixing block 32 will be inserted into the fixing hole on the outer wall of the power quality monitoring body 1, so as to connect, fix and assemble the power quality monitoring body 1;

[0033] When the electrical equipment vibrates, the U-shaped plate 2 is pressed down by the vibration, thereby pressing the slide plate 53 toward the third spring 52 through the inclined connecting rod 54, causing the third spring 52 to be compressed. At this time, the internal space of the outer casing 55 and the inner sleeve 56 will become larger, so that air can be inhaled through the air guide pipe 57. When the third spring 52 rebounds, the two slide plates 53 will move closer to each other, causing the internal space of the outer casing 55 and the inner sleeve 56 to become smaller, so that air can be exhausted through the air guide pipe 57. When inhaling and exhausting, a certain amount of damping is applied to the movement of the outer casing 55 and the inner sleeve 56, which is similar to the resistance and damping encountered when people squeeze or stretch an air pump. Combined with the buffering of the third spring 52, the U-shaped plate 2 and the power quality monitoring body 1 can be shock-absorbing.

[0034] The damping of the damping rod 42 and the buffering of the second spring 4 can further reduce the vibration of the U-shaped plate 2 on the bottom plate 41 and the power quality monitoring body 1, thereby improving the vibration reduction effect of the power quality monitoring body 1 and extending the service life of the internal components of the power quality monitoring body 1;

[0035] When the outer protective tube 55 and the inner sleeve 56 move, they will inhale and exhaust air through the top of the air guide tube 57, thereby accelerating the air flow around the heat sink 21, which is helpful for heat dissipation of the power quality monitoring body 1.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
