[0001] The present invention relates to the technical field of electric power detection devices, and in particular to a portable electric power detection device used in electric power construction. Background Art

[0002] Power detection equipment refers to equipment that tests, verifies, detects and accepts power production and power grid operation, and provides reliable protection for the safety and reliability of power operation. It refers to equipment that tests, verifies, detects and accepts power production and power grid operation, and provides reliable protection for the safety and reliability of power operation. Traditional power detection devices are generally boxes with handles. Generally, the detection tools and some equipment for power construction are placed inside the box, and then the box is held in the hand or taken with a shoulder strap.

[0006] Furthermore, the installation assembly also includes a first spring, one end of the first plug-in bracket passing through the top frame is fixed with the first spring, and the other end of the first spring is fixedly connected to the top frame, and a storage frame is fixed between the two top frames, and the cushion, mounting plate and annular belt can all be stored in the storage frame.

[0007] Furthermore, a slide plate is slidably mounted on the surface of the vertical frame, and a connecting shaft is rotatably mounted on the surface of the slide plate via a bearing, and the connecting shaft is fixedly connected to the middle and two side surfaces of the detection device box.

[0008] Furthermore, second insertion racks are slidably inserted into the bottoms of both sides of the vertical frame, and both ends of the bottom rod are fixedly connected to the second insertion racks.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention selects a pull ring and a pull rope on one side to pull the magnet block to move along the inside of the hollow groove. The magnet block contacts the sliding column on one side of the installation component through the push frame, pushes the arc plate out of the arc groove of the installation plate, and slides along the hollow groove until the installation component and the detection device box are moved to the side of the annular belt, which is convenient for manual detection of the power equipment.

[0017] 2. The present invention can maintain the stability of the installation component and the detection device box by sticking the pull rope on the outer surface of the annular belt and adsorbing the magnet block inside the hollow groove, and prevent the detection device box from moving during the detection process. The box is hung on one side of the waist of the maintenance personnel to save physical strength. Depending on the selection of the pull ring, the moving direction of the installation component and the detection device box is also different. They can move in two directions.

Under the action of external force, the arc plate can be pulled out from the arc groove, and the installation assembly can be disengaged from the installation plate, thereby adjusting the position and angle of the detection device box.

[0019] 4. The present invention wraps the detection device box around the top frame, vertical frame and bottom rod bracket. When the annular belt is worn around the waist of the maintenance personnel, the installation assembly and the detection device box are placed at the rear end of the annular belt through the sliding of the first plug-in bracket to avoid interfering with the climbing movement of the maintenance personnel.

[0020] 5. After the installation assembly of the present invention is moved to one side of the endless belt, different doors on the detection device box can be selected to open. Specifically, the detection device box is rotated by the connecting shaft, and the slide plate slides along the vertical frame. The second plug-in frame extends out from the inside of the vertical frame, thereby adjusting the range of the package and giving the detection device box space to rotate. The sliding blocks on the bottom rod and the top frame are circular, which can assist in the flipping of the detection device box.

[0021] 6. The present invention uses the elastic force of the second spring and the third spring to restore the limit wrapping of the detection device box, so that it has stability during the detection process. Different detection instruments or tools are configured inside different box doors on the detection box, which can be selectively used as needed, saving time in searching for detection tools. When not in use, the cushion, the mounting plate and the annular belt can be stored inside the storage frame by moving the first rack. The top rack acts as a handle, and the device can be lifted and moved.

[0022] 7. Compared with the prior art, the present invention uses an annular belt to bind the device around the waist, so as to facilitate climbing and moving. When moving to the specified position, the installation assembly and the detection device are moved to the corresponding side through the hollow groove of the annular belt, and the power equipment is detected by different instruments of the detection device. In this process, there is no need to lift the detection equipment manually, which can improve the stability during detection and reduce physical exertion. It is convenient to carry and climb, and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
