Description

Technical Field

[0001] The invention relates to the technical field of ray detection, in particular to a ray detection device with adjustable detection angle. Background Art

[0002] As an important part of power transmission, the safe operation of transmission lines is crucial to the stable operation of the power grid. As an important connecting device of the line, the tension clamp bears the tension and load of the wire, and its state directly affects the stability and safety of the line.

[0003] For the inspection of power transmission fittings on the line, the traditional UAV power transmission line inspection solution can only detect surface defects through visible light, such as missing connection bolts, surface cracks, etc. During the installation process, most tension clamps use hydraulic-based crimping methods, and the quality of crimping cannot be detected through traditional inspection methods. If the crimping quality does not meet the standards at the beginning of installation, after a period of operation, the wire may fall off at the crimping point, causing safety accidents. In order to detect the defects of tension clamps as early as possible to avoid accidents, traditional tension clamp radiographic inspection usually requires personnel to carry radiographic inspection equipment to climb up the tower for inspection, which has the following problems:

[0004] 1. Risk of personnel climbing up and down: Traditional non-destructive testing of tension clamps usually requires workers to climb up transmission towers or ladders to operate, which increases the danger of high-altitude operations. Workers may face unexpected risks such as falling and electric shock, posing a threat to their personal safety;

[0005] 2. Inconvenient to carry equipment: Traditional non-destructive testing equipment is usually large in size and heavy in weight, which is not convenient for workers to carry and operate. Auxiliary equipment such as pulleys and ropes are required to transport the equipment to the operating location, which increases the difficulty and time cost of the work;

[0006] 3. Low work efficiency: Since the traditional method requires personnel to manually operate the equipment, the work speed is relatively slow. At the same time, the operator needs to climb and adjust the position repeatedly, resulting in a waste of time;

[0007] 4. Safety and stability challenges: During high-altitude operations, the equipment is easily shaken and difficult to operate due to factors such as wind and weather. In addition, maintaining balance and stability is also a challenge. If the equipment is not firmly fixed, it may lead to errors and inaccurate detection results.

[0008] The patent with application number CN201880049330.6 discloses an X-ray inspection device for a drone, an X-ray inspection device using a drone, and an X-ray generating device for a drone, which specifically includes a first motor, a second motor, a first hook, and a second hook acting on the X-ray emitting device and the detector respectively.

[0009] The above device adjusts the positions of the X-ray emitting device and the detector respectively through a plurality of different motors and hooks. If the ray detection angle is to be flexibly adjusted at multiple angles, it is necessary to operate a plurality of different motors and hooks, which is complicated to use.

[0010] In summary, how to use a simple structure to achieve multi-angle radiation detection and make the device easy to operate is an urgent problem to be solved. Utility Model Content

[0011] The purpose of the utility model is to provide a radiation detection device with adjustable detection angle. A rotating drum and a suspension rope wound on the rotating drum are connected to different positions of the radiation detector. The suspension rope extends from the opposite side of the rotating drum. The extension length of the suspension rope is controlled by the rotation of the rotating drum, thereby driving the radiation detector to deflect and adjust the detection angle, thereby solving the problem of time-consuming and cumbersome operation of the prior art.

[0012] The purpose of the utility model is mainly achieved through the following technical solutions:

[0013] A ray detection device with adjustable detection angle, comprising a ray detector and an adjustment device;

[0014] The adjustment device comprises a suspension rope and a rotating drum, wherein the suspension rope is wound on the rotating drum, wherein the suspension rope comprises a first extension end and a second extension end connected to different positions of the radiation detector, and one end of the rotating drum is connected to a motor, and when the motor is started, one of the first extension end and the second extension end is further wound and the other is further released according to the rotation direction of the motor;

[0015] In actual applications where the radiation detector is hoisted for detection, in order to ensure the accuracy of the detection effect and the integrity of the detection, it is often necessary to adjust multiple angles to detect the object to be detected. However, since the radiation detector is hoisted for use, the device for adjusting the angle of the radiation detector should be as simple and light as possible. In the prior art, multiple independent motors and connecting devices are used to act on different positions of the radiation detector to adjust the deflection angle of the radiation detector. However, the adjustment of the angle of the radiation detector often involves position changes of multiple points. It is often necessary to adjust the positions of other points through another motor after adjusting a single point position. Adjusting multiple points together places high performance requirements on the product and is relatively complicated to operate.

[0016] The present application provides an adjustment device on the radiation detector, including a rotating drum and a suspension rope wound around the rotating drum, the suspension rope including a first extending end and a second extending end, the two telescopic ends are respectively connected to different positions of the radiation detector, and a motor is connected to the end of the rotating drum. When the motor rotates, the rotating drum rotates through the rotation of the motor, causing the suspension rope wound around the rotating drum to extend and shorten at the same time, thereby changing the longitudinal angle of the radiation detector.

[0017] The detection position and horizontal detection angle of the radiation detector can be controlled by a hoisting device such as an unmanned aerial vehicle, and the longitudinal angle of the radiation detector can be adjusted in combination with the adjustment device, so that the device can adjust the angle in all directions.

[0018] The adjustment device has a simple and light structure, is easy to operate and has high reliability during implementation.

[0019] Furthermore, the radiation detector includes a radiation machine and a display panel that are arranged opposite to each other, the radiation machine and the display panel are connected by a connecting tube, the connecting tube is fixedly connected to the radiation machine and the display panel, and the relative longitudinal position of the radiation machine and the display panel is adjustable;

[0020] One end of the suspension rope is connected to the X-ray machine, the other end of the suspension rope is connected to the display panel, and both ends of the connecting tube are respectively hingedly connected to the X-ray machine and the display panel.

[0021] The radiation detector includes a radiation machine and a display panel. The radiation machine emits radiation to penetrate the object to be detected, and the display panel captures the radiation that passes through the object to be detected and converts it into a visible image. Because the radiation detector of this device is suspended in the air, the movement of lifting equipment such as cranes and drones may cause the relative position of the radiation machine and the display panel to change, making the detection area between the two too large, small or disappearing, making it difficult for the device to effectively detect the object to be detected. Therefore, this application connects a connecting tube between the radiation machine and the display panel so that after the height of the radiation machine and the display panel is adjusted, the size of the detection area space can be maintained in a relatively stable state.

[0022] As a form of control of the angle of the radiation detector by the adjustment device, the two ends of the suspension rope are respectively connected to the radiation machine and the display board, and the motor drives the rotating drum to rotate, so that the hanging lengths left at the two ends of the suspension rope change in opposite directions and drive the connected radiation machine and display board to produce a change in height difference. After the relative height change process of the radiation machine and the display board occurs, the existing technology is used to change the deflection of the radiation machine and the display board so that the radiation machine and the display board are opposite. At this time, the articulation of the radiation machine, the display board and the connecting tube allows the connecting tube to adapt to the position change of the radiation machine and the display board under the condition of fixed length.

[0023] Furthermore, the radiation detector includes a radiation machine and a display panel that are arranged opposite to each other, the radiation machine and the display panel are connected by a connecting tube, the connecting tube is fixedly connected to the radiation machine and the display panel, and the relative longitudinal position of the radiation machine and the display panel is adjustable;

[0024] Both ends of the suspension rope are connected to the display panel. The connecting tube is a connecting tube with a non-adjustable length. The connecting tube is fixedly connected to the X-ray machine and the display panel.

[0025] As a control form of adjusting the angle of the radiation detector, the two ends of the suspension rope are respectively connected to the radiation machine and the display board, and the motor drives the rotating drum to rotate, so that the hanging lengths left at the two ends of the suspension rope change in opposite directions and drive the connected radiation machine and display board to produce a change in the height difference. At this time, the connecting tube connecting the radiation machine and the display board is deflected due to the change in height of the two ends, causing the radiation machine and the display board to deflect at the same angle.

[0026] Furthermore, the first extension end and the second extension end are both provided with a running part, and the running part can drive the first extension end and the second extension end to reciprocate along the axis direction of the rotating drum;

[0027] The first extending end and the second extending end both longitudinally penetrate the walking portion and can longitudinally move in the through channel of the walking portion.

[0028] A walking part is arranged on the first extending end and the second extending end, so that the first extending end and the second extending end can be longitudinally extended or shortened and move along the axial direction of the rotating drum with the movement of the walking part, so that the lifting rope can be evenly and tightly wound on the drum.

[0029] Furthermore, the walking part includes a rotating rod, a limiting rod and a guide block, and the guide block is simultaneously sleeved on the rotating rod and the limiting rod. The rotating rod and the limiting rod are parallel to the rotating cylinder, and the first extending end and the second extending end both longitudinally penetrate the guide block. A guide groove is provided on the rotating rod, and when the rotating rod rotates, the walking part reciprocates in the direction of the limiting rod.

[0030] The first extension end and the second extension end are both provided with a walking part, so that the walking part carries the first extension end and the second extension end to reciprocate along the axis of the drum. A rotating rod with a guide groove is provided on both sides of the drum, the rotating rod passes through the guide block, and the guide block also passes through a limit rod, the limit rod is coaxially arranged with the drum and the rotating rod, so that the suspension rope passes through the guide block and extends downward, and the suspension rope can be evenly wound or released on the surface of the drum during the reciprocating motion of the guide block along the rotating rod.

[0031] Furthermore, one end of the rotating drum and the rotating rod are both provided with gears, and the gears at the ends of the rotating drum are meshed with the gears on the two rotating rods.

[0032] The rotating drum and one end of the rotating rod are provided with gears meshing with each other, so that when the motor drives the rotating drum to rotate, the gear connected to the rotating drum rotates and drives the gear meshing with it to rotate, thereby linking the rotating rod and ensuring the movement trajectory of the suspension rope on the rotating rod.

[0033] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The suspension rope is wound around the rotating drum and includes two protruding ends respectively connected to different positions of the radiation detector. The protruding length of the protruding ends is controlled by the rotation of the rotating drum, thereby driving the radiation detector to deflect and adjust the detection angle;

[0035] 2. Use the number of turns of the suspension rope and the extension direction of the suspension rope relative to the rotating drum to achieve multiple control modes of the adjustment device on the radiation detector;

[0036] 3.

[0042] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0043] Example:

[0044] like Figure 1-Figure 3 As shown, a radiation detection device with adjustable detection angle includes a radiation detector 2 and an adjustment device 1;

[0045] The adjustment device 1 comprises a suspension rope 101 and a rotating drum. The suspension rope 101 is wound around the rotating drum. The suspension rope 101 comprises a first extension end and a second extension end connected to different positions of the radiation detector. One end of the rotating drum is connected to a motor 104. When the motor 104 is started, one of the first extension end and the second extension end is further wound and the other is further released according to the rotation direction of the motor.

[0046] In actual applications where the radiation detector 2 is hoisted for detection, in order to ensure the accuracy of the detection effect and the integrity of the detection, it is often necessary to adjust multiple angles to detect the object to be detected. However, since the radiation detector 2 is hoisted for use, the device for adjusting the angle of the radiation detector 2 should be as simple and light as possible. In the prior art, multiple independent motors 104 and connecting devices are used to act on different positions of the radiation detector 2 to adjust the deflection angle of the radiation detector 2. However, the adjustment of the angle of the radiation detector 2 often involves position changes of multiple points. It is often necessary to adjust the positions of other points through another motor 104 after adjusting a single point position. The adjustment of multiple points together places high requirements on product performance and is relatively complicated to operate.

[0047] The present application sets an adjustment device 1 on the radiation detector 2, including a rotating drum and a suspension rope 101 wound on the rotating drum, the suspension rope 101 includes a first extension end and a second extension end, and the two extension ends are respectively connected to different positions of the radiation detector 2, and a motor 104 is connected to the end of the rotating drum. When the motor 104 rotates, the rotating drum rotates through the rotation of the motor 104, so that the suspension rope 101 wound on the opposite sides of the rotating drum is stretched and shortened at the same time, so that the longitudinal angle of the radiation detector 2 changes;

[0048] As a preferred implementation scheme of the above scheme, the first extending end and the second extending end extend from opposite sides of the rotating drum and are connected to different positions of the radiation detector 2. The connection position between the suspension rope 101 and the radiation detector 2 is located at two opposite ends of the radiation detector 2. The connection points are far apart and opposite to each other, which makes it easy for the suspension rope 101 to control the radiation detector 2.

[0049] The detection position and horizontal detection angle of the radiation detector 2 can be controlled by a hoisting device such as a drone, and the adjustment device 1 is combined to adjust the longitudinal angle of the radiation detector 2, so that the device can adjust the angle in all directions.

[0050] The adjusting device 1 has a simple structure, is easy to operate and has high reliability during implementation.

[0051] Furthermore, the radiation detector 2 includes a radiation machine 203 and a display panel 201 which are arranged opposite to each other. The radiation machine 203 and the display panel 201 are connected by a connecting tube 202. The connecting tube 202 is fixedly connected to the radiation machine 203 and the display panel 201. The relative longitudinal position of the radiation machine 203 and the display panel 201 is adjustable.

[0052] One end of the suspension rope 101 is connected to the X-ray machine 203 , and the other end of the suspension rope 101 is connected to the display board 201 . Both ends of the connecting tube 202 are hingedly connected to the X-ray machine 203 and the display board 201 , respectively.

[0053] The radiation detector 2 includes a radiation machine 203 and a display board 201. The radiation machine 203 emits radiation to penetrate the object to be detected, and the display board 201 captures the radiation that passes through the object to be detected and converts it into a visible image. Because the radiation detector 2 of this device is suspended in the air, the movement of lifting equipment such as cranes and drones may cause the relative positions of the radiation machine 203 and the display board 201 to change, making the detection area space between the two too large, small or disappearing, making it difficult for the device to effectively detect the object to be detected. Therefore, this application connects a connecting tube 202 between the radiation machine 203 and the display board 201, so that after the height of the radiation machine 203 and the display board 201 is adjusted, the size of the detection area space can be maintained in a relatively stable state;

[0054] As a preferred implementation of the above solution, the middle portion of the connecting tube 202 is retractable to adapt to changes in the size of the object being detected.

[0055] As a form of controlling the angle of the radiation detector 2 by the adjusting device 1, the two extended ends of the suspension rope 101 are connected to the radiation detector 203 and the display board 201 respectively, and the motor 104 drives the rotating drum to rotate, so that the hanging lengths left at both ends of the suspension rope 101 change in opposite directions and drive the connected radiation detector 203 and the display board 201 to produce a height difference change. After the relative height change process of the radiation detector 203 and the display board 201 occurs, the deflection of the radiation detector 203 and the display board 201 is changed by using the existing technology, so that the radiation detector 203 and the display board 201 are opposite. At this time, the radiation detector 203, the display board 201 and the connecting tube 202 are hinged, so that the connecting tube 202 can adapt to the position change of the radiation detector 203 and the display board 201 under the condition of fixed length.

[0056] Furthermore, the radiation detector 2 includes a radiation machine 203 and a display panel 201 which are arranged opposite to each other. The radiation machine 203 and the display panel 201 are connected by a connecting tube 202. The connecting tube 202 is fixedly connected to the radiation machine 203 and the display panel 201. The relative longitudinal position of the radiation machine 203 and the display panel 201 is adjustable.

[0057] Both ends of the suspension rope 101 are connected to the display board 201, and the connecting tube 202 is a connecting tube 202 with a non-adjustable length, and the connecting tube 202 is fixedly connected to the X-ray machine 203 and the display board 201;

[0058] As a control form for adjusting the angle of the radiation detector 2 by the adjustment device 1, the two ends of the suspension rope 101 are respectively connected to the radiation machine 203 and the display board 201, and the motor 104 drives the rotating drum to rotate, so that the hanging lengths left at the two ends of the suspension rope 101 change in opposite directions and drive the connected radiation machine 203 and the display board 201 to produce a change in height difference. At this time, the connecting tube 202 connecting the radiation machine 203 and the display board 201 deflects due to the change in height of the two ends, driving the radiation machine 203 and the display board 201 to deflect at the same angle.

[0059] Furthermore, the first extension end and the second extension end are both provided with a running part, and the running part can drive the first extension end and the second extension end to reciprocate along the axis direction of the rotating drum;

[0060] The first extending end and the second extending end both longitudinally penetrate the walking portion and can longitudinally move in the through channel of the walking portion.

[0061] A walking part is arranged on the first extending end and the second extending end, so that the first extending end and the second extending end can be longitudinally extended or shortened and move along the axial direction of the rotating drum with the movement of the walking part, so that the lifting rope can be evenly and tightly wound on the drum.

[0062] Furthermore, the walking part includes a rotating rod 103, a limiting rod and a guide block, the guide block is sleeved on the rotating rod 103 and the limiting rod at the same time, the rotating rod 103 and the limiting rod are parallel to the rotating drum, the first extending end and the second extending end both longitudinally penetrate the guide block, the rotating rod 103 is provided with a guide groove, and when the rotating rod rotates, the walking part reciprocates along the direction of the limiting rod;

[0063] A walking part is arranged on the first extending end and the second telescopic end, and the walking part includes a rotating rod 103, a limiting rod and a guide block. The rotating rod 103 and the limiting rod are parallel to the rotating drum, and the guide block is simultaneously sleeved on the rotating rod 103 and the limiting rod. The rotating rod 103 is provided with a guide groove. When the rotating rod 103 rotates, the walking part reciprocates along the direction of the limiting rod; the extending end of the suspension rope 101 can move with the reciprocating motion of the walking part, so that the suspension rope 101 is wound or released on the rotating drum at a predetermined speed.

[0064] Furthermore, the rotating drum and one end of the rotating rod 103 are both provided with a gear 105, and the gear 105 at the end of the rotating drum meshes with the gears 105 on the two rotating rods 103;

[0065] The rotating drum and one end of the rotating rod 103 are provided with mutually meshing gears 105, so that when the motor 104 drives the rotating drum to rotate, the rotating rod 103 is linked, thereby ensuring the movement trajectory of the suspension rope 101 on the rotating rod 103 and the winding form on the rotating drum.

[0066] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
