The quality of power directly affects the lifespan of electrical equipment and the operation effect of the equipment. Therefore, in actual working conditions, it is necessary to use a detection device to detect power quality according to the actual situation.

[0003] A Chinese patent with the publication number CN 213934069 U discloses a power quality detection device, which specifically relates to the field of mechanical engineering. It includes a hanging plate, on the side surface of which a first connecting column is fixedly connected. The end of the first connecting column is fixedly connected with a connecting mechanism, and the other end of the connecting mechanism is fixedly connected with a second connecting column. On the upper and lower surfaces of the other end of the second connecting column, fixing plates are fixedly connected. On the other side of the fixing plate, a support column is fixedly connected. The lower surface of the support column is fixedly connected with a bottom plate, and at the four corners of the lower surface of the bottom plate, moving wheels are fixedly connected. The power quality detection device is clamped on the lower surface of the hanging plate. In the utility model, the power quality detection device is fixed on the lower surface of the hanging plate by pulling the buckle, and then by adjusting the knob, the first moving column and the second moving column move on the outer surface of the screw rod to control the distance between the first fixing block and the second fixing block.

[0004] During the detection of the circuit by the existing power quality detection device, it is usually necessary to carry the device to different locations for detection. The device has a large volume, resulting in poor portability. Therefore, a power quality detection device is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems existing in the prior art, the utility model proposes a power quality detection device.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A power quality detection device described in the present utility model includes a base. Four groups of pulleys are installed on the bottom side of the base. A handle is installed on the base. A groove is opened on the base. A shock-absorbing plate is installed in the groove. A lead screw is installed on the shock-absorbing plate. A first slider is sleeved on the lead screw. Two groups of guide rods are symmetrically welded on the shock-absorbing plate. A fixing plate is welded on the top sides of the lead screw and the two groups of guide rods. The lead screw penetrates through the fixing plate and a knob is welded on the top side. A second slider is sleeved on the guide rod. A connecting plate is jointly welded on the first slider and the second slider. A box body is welded on the side wall of the connecting plate. A box door is rotatably installed on the box body through a hinge. A detector is installed inside the box body. A display screen is installed on the detector. Buttons are installed on the detector. A storage box is installed on the side wall of the box body. A power cord and a data cable are placed in the storage box. Two groups of square grooves are opened on the side wall of the box body. A power socket and a data cable socket are installed on the detector. By rotating the lead screw, the first slider on it drives the box body to move vertically, and the box body drives the detector to move vertically, realizing the height adjustment of the detector, so that the detector can be adjusted in height according to the detection point. After the detection is completed, close the box door, rotate the knob in the reverse direction, move the box body onto the shock-absorbing plate, and store the power cord and the data cable in the storage box, realizing the rapid storage of the device. By pulling the handle, the four groups of pulleys rotate on the ground, realizing the portable handling of the device. This structure can carry the detector portably, which is beneficial to improving the portability of the device.

[0007] Preferably, a shock-absorbing component is installed between the shock-absorbing plate and the base. The shock-absorbing component includes a shock-absorbing block. The bottom side of the shock-absorbing block is fixedly connected to the bottom wall of the groove. A sliding groove is opened inside the shock-absorbing block. A piston block is assembled in the sliding groove. A moving rod is installed on the top side of the piston block. The top side of the moving rod is fixedly connected to the bottom side of the shock-absorbing block. Multiple groups of springs are installed between the shock-absorbing block and the base.

During the handling process, the pulleys vibrate on the ground, driving the base to vibrate, and the base drives the shock-absorbing plate to vibrate. During the vibration of the shock-absorbing plate, the springs deform and store energy. The piston block slides in the sliding groove, and the side wall of the piston block rubs against the sliding groove to generate frictional resistance. The deformation of the springs and the frictional resistance can reduce the vibration.

[0009] 1. The utility model realizes the height adjustment of the detector by rotating the lead screw. The lead screw drives the first slider thereon to move vertically, the first slider drives the box body to move vertically, and the box body drives the detector to move vertically, so that the height of the detector can be adjusted to match the detection point. After the detection is completed, close the box door, rotate the knob in the reverse direction, move the box body onto the shock-absorbing plate, and store the power cord and data cable in the storage box, realizing the rapid storage of the device. By pulling the handle, the four groups of pulleys rotate on the ground, realizing the portable handling of the device. This structure can carry the detector portably, which is beneficial to improving the portability of the device.

[0010] 2. During the handling process of the utility model, the pulleys generate vibrations on the ground, driving the base to vibrate. The base drives the shock-absorbing plate to vibrate. During the vibration of the shock-absorbing plate, the spring deforms and stores energy. The piston block slides in the chute, and the side wall of the piston block rubs against the chute to generate frictional resistance. The spring deformation and frictional resistance can reduce vibrations. At the same time, the frictional resistance consumes the energy of the spring, causing the spring to return to its original position, realizing the shock absorption of the shock-absorbing plate, that is, realizing the shock absorption of the box body and protecting the detector, which is beneficial to improving the protection performance of the device.
