Description

Technical Field

[0001] The utility model relates to the technical field of atmospheric pressure storage tanks, in particular to an ultrasonic detection device for atmospheric pressure storage tanks. Background Art

[0002] With the rapid development of my country's petrochemical construction, the number of vertical atmospheric pressure storage tanks has increased dramatically. Atmospheric pressure storage tanks refer to steel welded storage tanks with a design pressure of less than 0.1MPa, built on the ground, and used to store non-artificially refrigerated, non-highly toxic liquid media such as petroleum and chemicals. Storage tanks are widely used storage equipment in petrochemical production. In the oil refining industry, they are used to store various raw oils, semi-finished oils, finished oils, aromatic products and liquefied gas.

[0003] In the prior art, an ultrasonic detection device is often used to detect depressions on the outer surface of a normal pressure storage tank. However, in the prior art, it is difficult to verify when performing detection on several normal pressure storage tanks. In this way, if there is an abnormality in the ultrasonic detection probe during a single detection, it is difficult to detect the depression.

[0004] After searching, it was found that a Chinese patent document discloses a deformation detection device for atmospheric pressure storage tanks (publication number: 202321674195.9). The utility model provides a deformation detection device for atmospheric pressure storage tanks, which relates to the field of atmospheric pressure storage tank detection and includes a base plate. The top of the base plate is fixed with an inner gear ring through a support leg, the middle of the inner gear ring is fixed with a tank body, and a movable frame is provided on one side of the tank body. By installing an inner gear ring on the periphery of each tank body and starting the servo motor, the gear can be driven to rotate. With the cooperation of the inner gear ring, the movable frame can rotate one circle around the periphery of the tank body along the guide of the inner gear ring. The scanner on the movable frame can scan the tank body one circle, and the scan data is transmitted to the terminal in real time so that personnel can check the deformation of the tank body. The number and spacing of the scanners can be determined according to the scanning range of the selected scanner. The deformation detection device is concentrated on the movable frame, which reduces the volume of the detection device, thereby facilitating the movement of the detection device in the tank area when using it. However, there are still the following defects:

[0005] Although the above-mentioned atmospheric pressure storage tank deformation detection device has achieved a reduction in the volume of the detection device, thereby facilitating the movement of the detection device in the storage tank area when in use, it still has the problem of being difficult to verify when performing detection on several atmospheric pressure storage tanks. In this way, if there is an abnormality in the ultrasonic detection probe during a single detection, it is difficult to detect the depression condition. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] See also Figures 1-5 The utility model provides an ultrasonic detection device for atmospheric pressure storage tanks, including an ultrasonic detection platform 1 for atmospheric pressure storage tanks, a movable sleeve 2 is provided on the top outer wall of the ultrasonic detection platform 1 for atmospheric pressure storage tanks, and the movable sleeve 2 is horizontally movably connected to the top outer wall of the ultrasonic detection platform 1 for atmospheric pressure storage tanks, the top of the movable sleeve 2 and the top of the opposite side of the ultrasonic detection platform 1 for atmospheric pressure storage tanks are fixedly connected with a connecting block 3, and the corresponding end of the connecting block 3 is rotatably connected with a connecting piece 4, and the corresponding end of the connecting piece 4 is fixedly connected with a plug-in cover 5 for limiting the atmospheric pressure storage tank, the inner side wall of the plug-in cover 5 is fixedly connected with a wrapping balloon 6 with a circular ring structure, and the wrapping balloon 6 is an inflatable structure, and the outer side wall of the wrapping balloon 6 near the center point of the plug-in cover 5 is fixedly connected with a silicone anti-slip pad 7 with a circular ring structure.

[0025] By setting up the movable sleeve 2, the movable sleeve 2 can be moved toward the connecting block 3 fixedly connected to the top of the ultrasonic testing platform 1 for atmospheric pressure storage tanks during use, so that the distance between the two plug-in covers 5 is adapted to the size of the atmospheric pressure storage tank, and then the two ends of the atmospheric pressure storage tank are respectively plugged into the two plug-in covers 5. When the atmospheric pressure storage tank is plugged into the two plug-in covers 5, the wrapping balloon 6 fixedly connected inside the plug-in cover 5 is wrapped around the outer wall of one end of the corresponding atmospheric pressure storage tank. In this way, the atmospheric pressure storage tank can be quickly limited and fixed, and atmospheric pressure storage tanks of different sizes can be limited and fixed, which brings convenience to the detection.

[0026] The end of the left connecting block 3 away from the connecting piece 4 is movably connected to the first transmission wheel 8, and the end of the first transmission wheel 8 close to the connecting block 3 is transmission-connected to the corresponding end of the connecting piece 4. A second transmission wheel 11 is arranged below the first transmission wheel 8, and a transmission belt 10 is sleeved between the first transmission wheel 8 and the second transmission wheel 11. The end of the first transmission wheel 8 away from the connecting block 3 is fixedly connected to the output end of the motor 9.

[0027] By setting up the motor 9, during the detection process, the operation is output by the motor 9, thereby driving the first transmission wheel 8 to rotate. In this way, when the first transmission wheel 8 rotates, the corresponding phase plate 4 and the plug-in cover 5 for limiting and fixing the atmospheric pressure storage tank are driven to rotate synchronously. In this way, during the process of the atmospheric pressure storage tank, the atmospheric pressure storage tank can be inspected by multiple ultrasonic detection components 21. At the same time, when the first transmission wheel 8 rotates, the transmission belt 10 drives the second transmission wheel 11 to rotate synchronously.

[0028] One end of the second transmission wheel 11 passes through the side wall of the ultrasonic testing platform 1 applied to atmospheric pressure storage tanks, and extends to the interior of the ultrasonic testing platform 1 applied to atmospheric pressure storage tanks and is fixedly connected to one end of the first screw rod 12. The outer side wall of the first screw rod 12 is meshed with a first transmission screw rod sleeve 13, and the bottom end of the first transmission screw rod sleeve 13 is fixedly connected to the top of the guide slider 14. The guide slider 14 is horizontally movably connected to the inside of the guide slide groove 15, and the guide slide groove 15 is opened inside the mounting plate 16. The mounting plate 16 is fixedly connected between the inner walls on both sides of the ultrasonic testing platform 1 applied to atmospheric pressure storage tanks.

[0029] By setting the second transmission wheel 11, the second transmission wheel 11 rotates, driving the connected first screw rod 12 to rotate. In this way, the first screw rod 12 and the first transmission screw rod sleeve 13 constitute a screw transmission structure. In this way, the first screw rod 12 rotates, driving the first transmission screw rod sleeve 13 to move horizontally, so that the first transmission screw rod sleeve 13 drives the guide slider 14 to move horizontally inside the guide slide groove 15.

[0030] The bottom end of the guide slider 14 is fixedly connected to the bottom end of the inner side of the connecting frame 17 provided with a rectangular structure, and the top of the connecting frame 17 is fixedly connected to a detection frame 18, and the inner side wall of the detection frame 18 is fixedly connected to several installation cavities 19 at equal intervals, and the interior of the installation cavity 19 is plugged with a plug-in block 20, and the outer walls on both sides of the plug-in block 20 are in conflict with the outer wall of the conflict roller 23, and the conflict roller 23 is movably connected between the two mounting pieces 22, and the end of the mounting piece 22 away from the conflict roller 23 is fixedly connected to the outer wall of the damping bearing 24, and the inner side wall of the damping bearing 24 is fixedly connected to the end corresponding to the conflict roller 23 through a connecting rod, and one end of the plug-in block 20 is fixedly connected to an ultrasonic detection component 21, which includes at least a transmitting circuit, a receiving circuit and a signal processing unit.

[0031] By setting up the ultrasonic detection component 21, during the inspection of the atmospheric pressure storage tank, the connecting frame 17 is driven by the guide slider 14 to move horizontally, so that the linkage detection frame 18 is moved horizontally, and then during the movement of the detection frame 18, the atmospheric pressure storage tank is inspected by several ultrasonic detection components 21. The ultrasonic detection component 21 generates an ultrasonic signal through the transmitting circuit, and the electrical signal returned by the transmitting circuit is received by the receiving circuit, and amplified, filtered and other processing are performed. At the same time, the ultrasonic detection component 21 is easy to disassemble and assemble during use. The installation method of the ultrasonic detection component 21 is to plug it into the inside of the installation cavity 19 through the connected plug-in block 20, and to conflict with the interference roller 23, thereby limiting the plug-in block 20. At the same time, the interference roller 23 has a certain damping force. This method is adopted, which is convenient for operation when the ultrasonic detection component 21 is maintained.

[0032] A second screw rod 26 is provided above the first screw rod 12 and is movably connected between the inner walls on both sides of the ultrasonic testing platform 1 for atmospheric pressure storage tanks, and the outer side wall of the second screw rod 26 is meshedly connected with a second transmission screw rod sleeve 25. The top end of the second transmission screw rod sleeve 25 is fixedly connected to the bottom end of the movable sleeve 2, and one end of the second screw rod 26 is fixedly connected to one end of the adjustment knob 27 movably connected to the side wall of the ultrasonic testing platform 1 for atmospheric pressure storage tanks.

[0033] By setting the adjustment knob 27, when adjusting the spacing between the plug-in covers 5, by rotating the adjustment knob 27 forward or reversely, the second screw rod 26 is driven to rotate synchronously. Since the second screw rod 26 and the second transmission screw rod sleeve 25 constitute a screw transmission structure, when the second screw rod 26 rotates forward or reversely, the second transmission screw rod sleeve 25 is driven to move horizontally, so that the movable sleeve 2, the connecting block 3, the connecting piece 4 and the plug-in cover 5 components are moved horizontally synchronously, thereby adjusting the spacing between the plug-in covers 5.

[0034] When the embodiment of the present application is used: first, the atmospheric pressure storage tank to be inspected is fixed, the atmospheric pressure storage tank is passed through the inspection frame 18, and is plugged and fixed with the non-adjustable plug-in cover 5, and then the adjustment knob 27 is controlled to synchronize the horizontal movement of the movable sleeve 2, the connecting block 3, the connecting piece 4 and the plug-in cover 5, thereby adjusting the distance between the plug-in covers 5, and then the atmospheric pressure storage tank to be inspected is brought into contact between the two plug-in covers 5;

[0035] Secondly, when the atmospheric pressure storage tank is plugged into the two plug-in covers 5, the wrapping balloon 6 fixedly connected inside the plug-in cover 5 is wrapped around the outer wall of one end of the corresponding atmospheric pressure storage tank, so that the atmospheric pressure storage tank can be quickly limited and fixed;

[0036] Afterwards, the motor 9 outputs the operation, thereby driving the first transmission wheel 8 to rotate. In this way, when the first transmission wheel 8 rotates, the corresponding phase piece 4 and the plug-in cover 5 for limiting and fixing the atmospheric pressure storage tank are driven to rotate synchronously. In this way, the atmospheric pressure storage tank can be inspected by multiple ultrasonic detection components 21 during the process of the atmospheric pressure storage tank. At the same time, when the first transmission wheel 8 rotates, the transmission belt 10 drives the second transmission wheel 11 to rotate synchronously.

[0037] Finally, during the rotation of the second transmission wheel 11, the connected first screw rod 12 is driven to rotate. In this way, the first screw rod 12 and the first transmission screw rod sleeve 13 constitute a screw rod transmission structure. In this way, the first screw rod 12 is rotated to drive the first transmission screw rod sleeve 13 to move horizontally. In this way, the first transmission screw rod sleeve 13 drives the guide slider 14 to move horizontally inside the guide slide groove 15. At the same time, the guide slider 14 drives the connecting frame 17 to move horizontally, thereby linking the detection frame 18 to move horizontally. Then, during the movement of the detection frame 18, the atmospheric pressure storage tank is inspected by several ultrasonic detection components 21, and an ultrasonic signal is generated by the transmitting circuit contained in the ultrasonic detection component 21, and the electrical signal returned by the transmitting circuit is received by the receiving circuit, and amplified, filtered and other processing are performed. In this way, an ultrasonic detection device for atmospheric pressure storage tanks is completed.
