The distribution line high-voltage detection device structurally comprises a carrying assist device, a detection host, a detection port, a debugging end and a display screen, after the detection port is further improved, the position of the dustproof connecting sleeve can be determined on the basis that the electrified bolt of the parallel plate is locked into the electrified inserting block through the insulating frame of the detection port and the internal connecting groove, so that the dustproof block can be determined through the insulating shell at the top of the dustproof connecting sleeve and the internal connecting ring; therefore, the dustproof block can allow the line end to be inserted through the small through hole in the circle center, so that the line end can enter the connecting sleeve to complete overlapping contact electrification with the electrified bolt.

[0002] Electrical engineering construction is to complete the installation, commissioning and maintenance of electrical equipment and lines safely and reliably in accordance with design and specification requirements, within a certain time limit and in accordance with certain standards, so that the distribution lines installed during the operation can be tested for voltage, current, power and other aspects through special high-voltage detection devices, so that it can avoid damage caused by electrical parameters exceeding the specified values, thereby improving the safety of distribution lines; In summary, the inventors have found that the existing high-voltage detection devices for power distribution lines mainly have the following defects: since the detection ports of the current high-voltage detection devices are all exposed to the outside, and the slot areas are all hollow, so that when the entire device is idle, dust and impurities in the space are easily invaded and gathered inside the detection port, so that the influence of impurities and dust will affect the stability of subsequent line insertion and power-on inspection, which is very likely to cause poor contact and power failure, so that the detection strength of the current device is reduced and it does not have the characteristics of daily dust prevention; At the same time, the shell of the current high-voltage detection device is in the shape of a cube, so that when moving, the operator needs to lift the device to manually move it. Then, because the hands are supported on the bottom of the device, the upper part of the device will block the line of sight, which will cause inconvenience in manual movement. Summary of the invention

Subsequently, the insulating frame allows the parallel plate carrying the dustproof connecting sleeve and the power-on bolt to be embedded and fixed through the connecting groove, so that the dustproof connecting sleeve is in a vertical state. Then, the dustproof connecting sleeve can allow the circuit to be inserted straightly through the small through-hole in the center area of ​​the circle according to its own rubber characteristics, so that the end of the circuit can enter the interior of the dustproof connecting sleeve and overlap and contact with the top of the power-on bolt to be energized.

[0009] As a further improvement of the present invention, the inner wall groove of the insulating shell is semicircular in shape and matches the circular buckle shape of the edge of the connecting ring. The small through hole in the center of the dust block is circular and the dust block itself is made of rubber as a whole.

[0010] As a further improvement of the present invention, the insulating frame is also provided with a frame body, and the edge of the positioning frame fixes the partition column through a splicing block, so that the partition column will be connected to the edge of other frames through the splicing block, and the inner layer of the frame is covered with an insulating wall and a parallel plate and a dustproof connecting sleeve for spacing coordination.

[0011] As a further improvement of the present invention, the partition columns are vertical and perpendicular to the splicing blocks, and four groups are arranged on the outer edge of the frame, and the insulating wall completely covers the four sides of the inner wall of the frame.

[0012] As a further improvement of the present invention, the frame is provided with a solid piece, and the solid piece fixes the supporting block through the insulating wall of the inner wall, so that the supporting block can contact the four ends of the bottom layer of the parallel plate in combination with the solid piece. A slot is also opened on the outside of the solid piece and a restraining groove is opened in the center of the slot, so that the solid piece can be inserted and assembled with the splicing block through the slot and the restraining groove to position the partition column.

[0013] As a further improvement of the present invention, the solid piece is in a square shape and there are four bearing blocks on the inner wall, and the slots and the restraining grooves are both in a square shape that matches the shape of the splicing blocks.

[0014] As a further improvement of the present invention, the carrying aid is provided with a constant temperature limiter, the bottom of which is installed at the surface center of the bottom plate and the edge of the surface of the bottom plate is connected to a support column, which is connected parallel to the top plate through the upper end of the support column, and a handle is also welded at the surface center of the top plate.

The corners of the load-bearing plate are opened with power-on slots for electrical connection with the lower end of the detection host to provide power to the constant temperature block in the center of the surface.

[0017] As a further improvement of the present invention, the frame is installed parallel to the surface center of the base plate through a protrusion and the internal load-bearing plate includes a power-carrying plate, which uses the power-carrying groove on the edge to complete the electrical connection with the lower end of the detection host, and the constant temperature block will be combined with the load-bearing plate and the lower end of the detection host to contact each other.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is further improved on the detection port. Based on the insulation frame of the detection port and the internal connection groove, the power-on bolt of the parallel plate is locked into the power-on plug block, so that the position of the dustproof connecting sleeve can be determined. For this purpose, the insulating shell on the top of the dustproof connecting sleeve and the internal connection ring can determine the dustproof block. Therefore, the dustproof block can allow the line end to be inserted through the small through hole in the center of the circle, so that the line end can enter the interior of the connecting sleeve to complete the overlapping contact with the power-on bolt for powering on. For this purpose, the rebound cooperation of the rubber dustproof block can effectively improve the connection firmness between the detection port and the line end, and restore the diameter of the small through hole to the small hole shape when idle, avoiding the poor contact in the later stage caused by the invasion of a large amount of dust impurities.

[0019] 2. After further improvement of the insulating frame, the present invention can effectively improve the layout accuracy between the frames on the side of the detection host through the four groups of splicing blocks and dividing columns on the edge of the frame. According to the appropriate spacing, the mutual obstruction contact between multiple lines can be avoided. Then, the internal insulating wall can complete the contact with the bottom layer of the parallel plate through the bearing block to achieve the supporting effect, and then the solid part of the frame can complete the connection with the splicing block through the edge slot and the restraining groove, so as to achieve the spacing reinforcement stability played by mutual interlacing and restraining.

[0020] 3. After the present invention is further improved by the carrying assistant, the support column of the bottom plate can be connected with the top plate, and then the detection host can be loaded into the constant temperature limit body as a whole. For this purpose, the entire detection host can be directly lifted up by the handle of the top plate, replacing the original lifting method to manually control the displacement process. Then, the frame of the constant temperature limit body can supply power to the central constant temperature block through the power-on plate of the internal load-bearing plate when the detection host is working, so that the constant temperature block can balance the temperature of the detection host, prevent the over-high temperature caused by long-term detection, and ensure the stability of high-voltage detection of the line.
