Example 1:

the X-ray detection device for the live detection of the extra-high voltage line helicopter shown in the combined description and the figures 1-5 comprises a main frame 1 for supporting and equipment installation, wherein an X-ray machine 2 and a detector 3 are oppositely installed on the main frame 1,

a main control box 5 for controlling the X-ray machine 2 and the detector 3 is detachably and fixedly installed at the lower part of the main rack 1, a pair of wire hanging mechanisms 6 is further installed on the main rack 1, an upper guide 7 for guiding the detected extra-high voltage cable into the wire hanging mechanisms 6 and a lower guide 8 installed between the two wire hanging mechanisms 6 on the main rack 1 are arranged on the left side and the right side of any one of the wire hanging mechanisms 6, and a smooth opening for facilitating the extra-high voltage cable to slide in is formed between the upper guide 7 and the lower guide 8;

a steering mechanism 4 for controlling the rotation of the detector 3 is further arranged between the main frame 1 and the detector 3, and the detector 3 rotates by an angle ranging from 1 degree to 180 degrees in a direction deviating from the X-ray machine 2; and a pylon 9 fixedly mounted on the main frame 1 for connection to a helicopter.

The structure and the working principle are as follows:

the working principle of the X-ray detection device is basically not substantially different from that of the existing X-ray detection device, communication is established with the main control box 5 through the terminal control device, X-rays are emitted through the X-ray machine 2, transillumination is carried out on a high-voltage transmission cable arranged between the X-ray machine 2 and the detector 3, imaging is carried out on the detector 3, a clear X-ray sheet of a high-voltage transmission cable or hardware fitting is obtained, defects existing in the high-voltage transmission cable are obtained through analysis of the X-ray sheet, and therefore maintenance and replacement are carried out in advance, and the problem that huge economic loss is caused by breakage or other power failure accidents caused by the defects is avoided.

However, in order to highlight the application scenarios and the technical effects brought by the structure of the present embodiment, before explaining the structural principle, the applicant first makes necessary explanation on the existing X-ray detection manner of the high-voltage transmission line. The detection of the high-voltage transmission line is divided into power failure detection and live detection, as is well known, if the power failure detection is adopted, the safety of the high-voltage transmission line is fully guaranteed, and at least in ionizing radiation, the electric shock risk is avoided; but the detection of power outage is almost impossible to see in practical applications. The main reason is that the loss caused by the power failure of the high-voltage transmission line and the extra-high voltage transmission line is too large and can hardly bear, so that the high-voltage transmission line can not adopt power failure detection under normal conditions, and the research on the power failure detection is of no significance.

In the field of live detection, equipotential detection and ground potential detection can be generally divided. First, the ground potential detection is described, and the object to be detected and the person to be detected are not at the same potential, and there is a potential difference. This potential difference generally ranges from tens of kilovolts to hundreds of kilovolts, so that insulation protection of the inspector is very important, and a slight leakage will have extremely serious consequences. Because the testing personnel are in the ground potential, therefore the current situation of detection, position, precision can not be observed by audio-visual, nevertheless because keep away from high-voltage transmission cable, the security can be ensured relatively.

Finally, equipotential detection is that there is almost no potential difference between the person being detected and the high-voltage line being detected, i.e. equipotential. The detection mode has the greatest advantages that operators can clearly and directly carry out X-ray detection on the detected transmission cables and fittings, and can quickly and accurately obtain high-quality X-ray films; however, the advantages are very outstanding, and the disadvantages are also obvious; because the operator is at the same potential with high-voltage transmission line, under the closely spaced distance, although can do more protection, also will suffer strong ionizing radiation, be harmful to the health of detection personnel.

In view of this, the detection device provided in this embodiment is designed mainly for detecting live helicopter, and the specific principle is as follows:

the detection device provided by the embodiment is composed of three functional structures, which are respectively:

the detection functional structure is characterized in that a main frame 1, a main control box 5, an X-ray machine 2 and a detector 3 are adopted, and a detector establishes communication with the main control box 5 and controls the X-ray machine 2 and the detector 3 to work, so that a high-quality X-ray film is obtained for subsequent defect analysis. Because the X-ray machine 2 and the detector 3 are both arranged on the fixed main frame 1, the distance between the X-ray machine and the detector is matched in advance, and each parameter is set for the high-voltage transmission line, so that an ideal X-ray film can be shot.

The hanging functional structure and the hanging function can hang the whole detection device on the detected high-voltage transmission line, and are mainly born by the hanging mechanism 6, and the hanging mechanism 6 shown in the figure 1 is combined with the specification and is provided with a plurality of rollers for hanging the line.

The guide function structure is used for high-altitude detection operation, and the detection device is effectively arranged on the high-voltage transmission line, which is a difficulty of detection operation and is also a working part with a relatively high danger coefficient. Because the detection device has large self-mass and usually has the difference of dozens of kilograms to dozens of kilograms, the previous equipotential detection only aims at the upper tower and the lower tower of the detection device to consume a large amount of time, and a large amount of labor cost and time cost are input; particularly, detection in remote mountain areas, valleys and canyon areas is difficult to imagine, efficiency is extremely low, and danger coefficient is high. The problem of terrain danger can be fundamentally avoided by adopting helicopter hoisting detection. Even the more dangerous the terrain, the more likely and advantageous the use of helicopters or heavy-duty drones will be. However, it is a difficult problem how to mount the detection device on the high-voltage transmission line effectively and accurately due to the high-altitude operation. For this reason, the guiding function plays a crucial role. With reference to the upper guide 7 and the lower guide 8 shown in fig. 1, 3-5, the upper guide 7 wraps the outer contour of the wire hanging mechanism 6, and similarly, the lower guide includes the outer contour of the steering mechanism 4, so that when trial hanging is performed, the high-voltage transmission line is not accurately hung in time, and under the guiding action of the upper guide 7 and the lower guide 8, the transmission line is in a completely-falling state or a completely-hanging state, so that the transmission line is prevented from contacting other structural members; meanwhile, a smooth opening which is convenient for the extra-high voltage cable to slide in is formed between the upper guide 7 and the lower guide 8, so that the success of one-time hanging can be greatly improved. As shown in fig. 5, since the upper guide 7 has a free end, after the high-voltage cable is hung, the high-voltage cable can be naturally hung on the wire hanging mechanism 6 under the action of the gravity of the detection device itself and can be continuously and reciprocally slid and detected on the high-voltage transmission line according to the detection requirement. After the detection is finished, the helicopter is only required to apply an upward pulling force to the detection device through the hanging bracket 9, at the moment, the upper guider 7 restores to the initial position under the action of the self-deformation elastic force, and the auxiliary off-line restores to the state shown in the figure 4, so that the current detection is finished.

The steering mechanism 4 is not beneficial to wire hanging because the detector 3 needs to be aligned with the X-ray machine 2 when in a detection state, even the detector 3 can block the normal wire hanging of a high-voltage wire, therefore, the steering mechanism 4 needs to rotate the detector 3 from the state shown in the figure 4 to the state shown in the figure 6 before the detector is hung, so that the upper part and the lower part of a smooth opening are both shielded, and after the wire hanging is finished, the detector 3 is rotated from the state shown in the figure 6 to the state shown in the figure 5 to start the detection work.

Example 2:

in this embodiment, a further optimization design is performed on the basis of embodiment 1, and specifically, as shown in fig. 1-2, the steering mechanism 4 includes a support shaft 48 having one end fixedly connected to the main frame 1, a plurality of spiral grooves 49 are uniformly distributed on a side wall of the support shaft 48, the spiral grooves 49 extend spirally in an axial direction from a free end surface, a deflection angle of a starting point of any spiral groove 49 in a radial plane of the support shaft 48 is not less than 180 °, that is, a rotation angle of any spiral groove 49 from the starting point to an end point cannot be less than 180 °, which is set to ensure that the detector 3 can realize an optimal 180 ° deflection, so as to give way for a hanging wire to the greatest extent, improve a success rate of one-time hanging wire, and reduce a blocking of the hanging wire. The support shaft 48 is sleeved with a first shaft sleeve 43, a plurality of grooves for containing steel balls are arranged in the first shaft sleeve 43, and the distribution positions of the grooves correspond to any one of the spiral grooves 49 one by one; the purpose of the steel ball matching is two: one is to ensure the smoothness of the rotation of the first shaft sleeve 43 on the support shaft 48, i.e. the smoothness of the deflection of the detector 3; secondly, the abnormal deflection of the detector 3 is strictly limited by the spiral groove 49, so as to ensure that the deflection angle of the detector 3 is in a precise and controllable state all the time. The first shaft sleeve 43 is fixedly connected with a support 31, and the detector 3 is installed on the support 31; the device also comprises a driving mechanism which is rotatably arranged on the supporting shaft 48 and is used for driving the detector 3 to rotate and axially move along the supporting shaft 48, and a stabilizing mechanism for keeping the detector 3 balanced.

In this embodiment, the driving mechanism includes at least one bearing 46 fixedly disposed on the supporting shaft 48, a servo motor 41 is fixedly mounted on an outer ring of the bearing 46, the servo motor 41 is connected with a lead screw 42 in a driving manner, and the lead screw 42 is in threaded connection with the supporting column 31. Because the spiral groove 49 is designed as a continuous spiral, when the detector 3 needs to deflect at any angle, the steel ball rolls along with the spiral groove 49, that is, corresponding axial displacement occurs, however, the bearing 46 for fixing the servo motor 41 only allows the servo motor 41 to axially rotate along with the detector 3, but cannot axially displace at all, and in such a structure, the axial position relation between the detector 3 and the servo motor 41 needs to be changed, and only the rotation of the screw rod 42 can be realized, so that the deflection angle of the detector 3 can be accurately controlled by using the advantage of high-precision controllability of the servo motor 41.

Still further preferably, the stabilizing mechanism comprises at least one sliding sleeve 44 fixedly connected to the outer side of the first shaft sleeve 43, and a threaded sleeve 47 fixedly connected to the outer side wall of the bearing 46, wherein the threaded sleeve 47 is fixedly connected with a guide rod 45, and the guide rod 45 is slidably disposed in the sliding sleeve 44. The guide rod 45 serves to further increase the stability of the detector 3 and to reduce the lateral stress of the spindle 42, so that the spindle 42 only needs to bear axial stress.

In order to improve the stability of the stabilizing mechanism and enable the stabilizing mechanism to be compatible with bearings with smaller axial dimensions, preferably, the number of the bearings 46 is two, two threaded sleeves 47 are arranged on any one of the bearings 46, the guide rods 45 are arranged on any one of the threaded sleeves 47, and the number and the positions of the sliding sleeves 44 correspond to those of the guide rods 45.

As a further preferred structural arrangement of this embodiment, in order to improve the stability of the detector 3 in the working state, it is preferable that any one of the spiral grooves 49 further extends in the axial direction near one end of the main frame 1 to form a straight groove for clamping the first shaft sleeve 43, as shown in detail in fig. 7. The flat slot design is used for positioning the stability of the working state of the detector 3. When the steel balls are in the spiral groove 49, although the detector 3 is under stress action under the axial stress action of the screw rod 42, when the screw rod 42 further draws the distance between the pillar 31 and the servo motor 41 until the steel balls enter the straight groove, under the limiting action of a plurality of steel balls, the pillar 31 is always at the current angle and cannot deflect, so that the stress action of the screw rod 42 and the guide rod 45 is relieved, and the structure is more stable.

Example 3:

the embodiment is a further optimized and improved design based on embodiment 1 or embodiment 2, and specifically, as shown in fig. 5 to fig. 8 in the description, in order to improve that the detection device can be hung on a power transmission cable as quickly and efficiently as possible when a helicopter hoists the detection device, the problem that the detection device can be hung effectively only by multiple operations due to blocking of structural members such as the X-ray machine 2 or the main frame 1 is solved. Preferably, go up director 7 and form for the smooth metal pole bending of integrated into one piece surface, one end fixed connection be in stiff end on the main frame 1, the other end is the free end, the stiff end comprises vertical section, horizontal segment, first segmental arc 71 and the second segmental arc 72 that connect gradually, the string line mechanism 6 is in go up the planar projection in director 7 place go up the within range that director 7 encloses.

Further, the lower guide 8 is formed by bending a metal rod with a smooth surface, which is integrally formed, two ends of the metal rod are fixedly connected to the main frame 1, and the lower guide 8 includes a second straight section 82 with a horizontal position higher than the steering mechanism 4, and a first straight section 81 with a horizontal position lower than the steering mechanism 4.

In order to meet the detection requirement of the multi-split power transmission line, the wire hanging mechanism 6 preferably comprises an L-shaped bracket 61 fixedly mounted on the main frame 1, and a roller group 62 mounted on the L-shaped bracket 61 and used for hooking the extra-high voltage cable. Adopt roller train 62 can adapt to the mount of the many divisions of transmission line of current high voltage transmission net, roller train 62 mount mode has stability height, and the advantage that self-adaptability is strong need not to adjust, and it is smooth and easy to slide.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
