DETAILED DESCRIPTION

[0021] The application will be further described below in conjunction with specific examples.

[0022] To solve the problem that the device may fall from the surface of the tower and be damaged when detecting the fan tower, causing the data collected by the ultrasonic, magnetic powder or visual detection equipment carried to be distorted, affecting the detection effect, and the falling may hit the equipment at the bottom of the tower or the ground personnel, causing a safety accident, such as Figure 1 Figure 6 As shown in the figure: A fan tower detection device, comprising a main detector 1 and a locking mechanism 2 arranged on one side of the surface of the main detector 1, the main detector 1 comprising a wall climbing robot 101 arranged in the middle of the main detector 1, the front end of the wall climbing robot 101 is provided with a mounting rack 102, and the front end of the mounting rack 102 is provided with a position sensor 103 on both sides, and the front end of the mounting rack 102 is provided with a detection head 104, the wall climbing robot 101 is a magnetic suction wall climbing device of the existing principle, which cooperates with the existing position sensor 103 and the detection head 104 which is a HSD-TOFD module, realizes automatic scanning in the mode of automatic walking and remote sensing control, and completes the detection of the weld of the fan tower.

[0023] The locking mechanism 2 comprises a winding frame 201 arranged on one side of the surface of the wall climbing robot 101, the middle of the winding frame 201 is provided with a winding drum 202, and the middle of the winding drum 202 is provided with a protective belt 203, and the bottom of the protective belt 203 is fixed with a plug 204.

[0024] ​One end of the winding drum 202 is provided with a rotating ratchet 205, and the rear middle part of the rotating ratchet 205 is provided with a counterweight rotating block 206, the lower surface of the rear surface of the rotating ratchet 205 is provided with a first clamp head 207, and the outer part of the first clamp head 207 is provided with a fixed ratchet 208, the surface middle part of the rotating ratchet 205 is provided with a sliding groove 209, the other end of the winding drum 202 is fixedly provided with a fixed rotating shaft 211, and the front end of the fixed rotating shaft 211 is provided with a spiral spring 210, the surface outer side of the fixed rotating shaft 211 is connected with a double set of ratchets 212, and the middle part of the fixed rotating shaft 211 is fixedly provided with a fixed sleeve 213, the inner side middle part of the fixed sleeve 213 is provided with a first spring 214, and the front end of the first spring 214 is connected with a sliding pull rod 215, the top of the sliding pull rod 215 is fixedly provided with a counterweight ring 216, and the outer side upper part of the double set of ratchets 212 is provided with a second clamp head 217.

[0025] The winding drum 202, the rotating ratchet 205, the counterweight rotating block 206 and the first clamp head 207 are rotationally connected with the winding frame 201, and the counterweight rotating block 206 is rotationally connected with the sliding groove 209, the fixed ratchet 208 is fixedly connected with the winding frame 201, the front end of the spiral spring 210 is fixedly connected with the fixed rotating shaft 211, and the tail end of the spiral spring 210 is fixedly connected with the winding frame 201.

[0026] The double set of ratchets 212 are two groups of ring-shaped ratchets fixed on the fixed rotating shaft 211, and a certain gap is arranged in the middle of the double set of ratchets 212, and the convex teeth of the double set of ratchets 212 are opposite to the convex teeth of the rotating ratchet 205, the sliding pull rod 215 is elastically connected with the fixed sleeve 213 through the first spring 214, and the fixed sleeve 213, the first spring 214, the sliding pull rod 215 and the counterweight ring 216 are arranged in four groups about the fixed rotating shaft 211, and the second clamp head 217 is rotationally installed on the winding frame 201 and is clamped with the double set of ratchets 212, and through the locking mechanism 2, the device can be protected when falling from the surface of the fan tower drum, so as to prevent the device from being damaged and affecting the safety of detection.

[0027] Through the plug 204, after the wall-climbing robot 101 is arranged on the surface of the fan tower drum, the safety belt 203 is smoothly drawn out from the winding drum 202, so that the safety belt 203 winds around the tower drum once, and finally the plug 204 is inserted and matched with the safety belt socket structure arranged on the other side of the wall-climbing robot 101, so that the safety belt 203 forms a binding type protection for the wall-climbing robot 101, and when the winding drum 202 rotates clockwise, the spiral spring 210 rotates and tightens, at this time the double set of ratchets 212 will be clamped by the second clamp head 217, so that the winding drum 202 cannot be recovered and rotated by the elastic force of the spiral spring 210, and the extracted safety belt 203 has a certain relaxation force, which avoids that the safety belt 203 is recovered and tightly attached to the surface of the tower drum, thereby affecting the movement of the wall-climbing robot 101.

[0028] When the wall-climbing robot 101 loses contact from a high place on the tower wall surface due to the tower wall surface characteristics, environmental interference, and changes in the state of the robot itself, resulting in irregular or inclined falling, the reaction force of the wall-climbing robot 101 with a certain weight falling downward will instantly generate a powerful pulling force between the protective belt 203 and the tower wall, at this time the protective belt 203 will drive the winding roller 202 to rotate quickly, this sudden and rapid rotating force will make the counterweight rotating block 206 be affected by the centrifugal force and rotate along the sliding groove 209 on the surface of the rotating ratchet 205, so that the rotating counterweight rotating block 206 will press the first clamp 207 downward, so that the first clamp 207 is clamped with the fixed ratchet 208, at this time the clamped first clamp 207 will be limited by the fixed ratchet 208, so that the rotating ratchet 205 and the winding roller 202 no longer continue to rotate, so that the protective belt 203 stops being pulled out, at the same time, when the winding roller 202 and the fixed rotating shaft 211 suddenly and quickly rotate, the first spring 214, the sliding pull rod 215 and the counterweight ring 216 will also be affected by the centrifugal force, so that the sliding pull rod 215 extends outward from the fixed sleeve 213, and the counterweight ring 216 expands outward, which will press the second clamp 217 to move upward, so that the second clamp 217 loses the ability to clamp and limit the double ratchet 212, at this time the helical spring 210 with a certain strength and elasticity will drive the winding roller 202 to rotate in the opposite direction under the action of its own expansion force, so that the winding roller 202 generates a certain recovery effect on the protective belt 203, so that the protective belt 203 can be tightened to generate a tight adhesion force and friction force on the tower wall surface, thereby improving the limiting and protective effect of the protective belt 203 on the wall-climbing robot 101. By using the pulling and tightening of the protective belt 203 when the wall-climbing robot 101 suddenly falls, the falling distance of the robot can be controlled to be much smaller than the height of the tower, so as to avoid the device from directly falling and hitting the ground or equipment, at the same time, the protective belt 203 can absorb impact energy through deformation, thereby reducing the damage degree of the robot body and the detection equipment.

[0029] In order to solve the problem that the device is difficult to move due to the resistance of the protective structure or the attachment of impurity particles on the tower wall surface during operation, thereby easily affecting the stability and safety of detection, as shown in Figure 1 and Figure 2 and Figure 7 - Figure 9 ​The upper side of the main body detector 1 is provided with a ventilation mechanism 3 for ventilation expansion, the ventilation mechanism 3 comprises an exhaust fan 301 installed in the middle of the upper surface of the wall climbing robot 101, the upper side of the exhaust fan 301 is connected with a gas guide pipe 302, the bottom of the gas guide pipe 302 is provided with a mounting head 303, the lower side of the mounting head 303 is provided with a mounting seat 304, the mounting seat 304 is fixedly connected with the front end surface of the protective belt 203, and the exhaust fan 301 is a heat dissipation fan of the wall climbing robot 101 itself.

[0030] The inner side of the middle of the protective belt 203 is provided with an inflation cavity 305, the outer side of the inflation cavity 305 is communicated with an exhaust valve port 306, the mounting head 303 and the mounting seat 304 are screw-connected, the exhaust fan 301, the gas guide pipe 302, the mounting head 303, the mounting seat 304 and the inflation cavity 305 are communicated, and the protective belt 203 is made of air-tight material.

[0031] The surface of the locking mechanism 2 is provided with a lead-through mechanism 4 for ventilation control, the lead-through mechanism 4 comprises a fixed cylinder 401 arranged in the interior of the protective belt 203, the inner side of the middle of the fixed cylinder 401 is provided with a sealing sliding sleeve 403, the bottom of the sealing sliding sleeve 403 is fixedly provided with a pressing rod 402, the surface of the fixed cylinder 401 is provided with ventilation holes 404 on both sides of the upper side, the inner side of the upper side of the sealing sliding sleeve 403 is provided with a second spring 405, the ventilation holes 404 are communicated with the inflation cavity 305, the inflation cavity 305 arranged in the interior of the protective belt 203 is of a segmented structure, and each segment is communicated by the ventilation holes 404 of the fixed cylinder 401.

[0032] After the protective belt 203 is inserted, the mounting head 303 and the mounting base 304 are installed together. When the exhaust fan 301 is used to exhaust heat, part of the gas can enter the air-filled cavity 305 in the protective belt 203 through the air guide pipe 302, the mounting head 303, and the mounting base 304. At this time, the surface of the extracted part of the protective belt 203 is in a relaxed state, and the second spring 405 in the fixed cylinder 401 corresponding to the extracted part of the protective belt 203 is in an extended state, so that the sealing sleeve 403 is pushed downward, the air hole 404 is exposed, and the filled gas can enter the segmented air-filled cavity 305. The rolled protective belt 203 is pressed by the contact surface, so that the pressing rod 402 compresses the sealing sleeve 403 upward, and the sealing sleeve 403 blocks the air hole 404, so that the gas cannot enter the rolled protective belt 203, thereby avoiding affecting the stability of the rolled protective belt 203 and the subsequent extraction. At this time, the extracted part of the protective belt 203 can be inflated to form an air bag around the protective belt 203 wrapped around the tower cylinder, thereby further reducing the friction generated by the protective belt 203 during normal operation of the wall climbing robot 101, and ensuring the stability of the wall climbing robot 101 during driving and detection. The air bag of the protective belt 203 can also provide a certain buffer when falling, reducing the possibility of damage to the device and detection. Through the exhaust valve 306, the excess gas can be sprayed outwards, thereby avoiding damage caused by continuous expansion of the protective belt 203. At the same time, the sprayed gas is also beneficial to the cleaning of the tower surface, reducing the influence of impurities and particles on the driving and detection of the wall climbing robot 101.

[0033] In order to solve the problem that the device is easy to fall too fast or the contact force is too large, thereby causing damage and damage to the detection data, as shown in Figure 1 and Figure 2 and Figure 10 and Figure 11 as shown: The main detection instrument 1 is installed with an adsorption mechanism 5 for secondary protection on both sides of the lower part of the inside. The adsorption mechanism 5 includes an inner cylinder 501 installed inside the wall climbing robot 101. The middle part of the outer surface of the inner cylinder 501 is installed with a battery pack 502, and the upper part of the inside of the inner cylinder 501 is installed with an electromagnetic suction plate 503. The outer side of the electromagnetic suction plate 503 is connected with a connecting lead 504, and the front end of the connecting lead 504 is installed with a switch head 505.

[0034] The inner side of the inner cylinder 501 is installed with a support disc 506, and the middle part of the support disc 506 is fixedly connected with a connecting pull rod 507. The lower part of the support disc 506 is installed with a third spring 508, and the support disc 506 is elastically connected with the inner cylinder 501 through the third spring 508. The support disc 506 is made of magnetic material.

[0035] The bottom of the connecting pull rod 507 is provided with a ball joint 509, and the bottom of the ball joint 509 is provided with a suction disc 510, which is a permanent magnet. Through the suction mechanism 5, the wall-climbing robot 101 can be prevented from falling again.

[0036] When the wall-climbing robot 101 works normally, the support disc 506 is pulled upward, the electromagnetic suction plate 503 is powered on to electromagnetically adsorb the support disc 506, the third spring 508 is stretched upward to make the suction disc 510 retract into the built-in cylinder 501, and when the counterweight ring 216 expands outward, the counterweight ring 216 will contact and press the switch head 505, and the switch head 505 is a power supply switch of the battery pack 502 and the electromagnetic suction plate 503. At this time, the electromagnetic suction plate 503 will be powered off, and the support disc 506 loses the adsorption force. Under the action of the recovery force of the third spring 508, the suction disc 510 extends outward, and by using the omnidirectional variable angle property of the ball joint 509, the extended suction disc 510 can be adsorbed on the surface of the tower drum. At the same time, the third spring 508 can perform certain buffering when adsorbed, so as to further limit the falling of the wall-climbing robot 101. In combination with the locking mechanism 2, the wall surface is adsorbed by mechanical locking and magnetic force, so as to improve the effect of protecting the wall-climbing robot 101 from falling, and ensure the safety and stability of the device and detection.
