DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] For example, see Figures 1 to 3 The utility model provides a technical solution: a boiler wear-proof and explosion-proof maintenance device, comprising a bottom plate 1, four threaded holes 2 for threaded fixing are symmetrically opened on the surface of the bottom plate 1, a first motor 3 is fixedly installed on the central upper surface of the bottom plate 1, a threaded rod 4 for adjusting the maintenance height is fixedly connected to the output end of the first motor 3, a displacement sleeve 5 is sleeved on the external thread of the threaded rod 4, and a second motor 9 for adjusting and adapting to different inlet angles of the boiler is fixedly installed on one side surface of the displacement sleeve 5;

[0024] The output end of the second motor 9 is fixedly connected with a collar 10, an outer shell 11 is fixedly sleeved inside the collar 10, the lower end of the outer shell 11 abuts against a fixing plate 15, and an electromagnetic ultrasonic module 16 and three cameras 17 electrically connected to the maintenance background are fixedly installed on one side surface of the fixing plate 15.

[0025] More specifically, in this embodiment, the bottom plate 1 is firmly fixed by the threaded hole 2, and the operator can start the first motor 3 according to the inlet height of the boiler to be inspected. The output shaft of the first motor 3 drives the threaded rod 4 to rotate accordingly, and the displacement sleeve 5 threadedly sleeved on the outside of the threaded rod 4 will also perform a corresponding height displacement.

[0026] Subsequently, the second motor 9 is started, and the output shaft of the second motor 9 drives the collar 10 and the outer shell 11 to rotate at a corresponding angle until the electromagnetic ultrasonic module 16 and the camera 17 on the fixed plate 15 are rotated to the maintenance inlet of the boiler, thereby meeting the maintenance of boilers at different inlet angles and improving the practicality of the boiler anti-wear and explosion-proof maintenance device. In addition, in order to ensure the normal use of the first motor 3 and the second motor 9, a protective shell 19 is provided on the outside of the first motor 3 and the second motor 9 to avoid damage caused by accidental contact of external objects to the first motor 3 or the second motor 9, and the symmetrical surface of the protective shell 19 is provided with a heat dissipation groove 20 for heat dissipation, which can effectively achieve the heat dissipation purpose for the normal operation of the first motor 3 and the second motor 9.

[0027] Furthermore, since the optical zoom lens 18 is fixedly mounted on the camera 17, the camera 17 can effectively achieve the purpose of magnifying and clearly displaying the details inside the boiler through the optical zoom lens 18 in the dim boiler, and provide sufficient brightness to make the image clearly visible. In addition, the optical zoom lens 18 with model VP-LZ-80104 has a high-resolution zoom lens and a high numerical aperture telecentric optical path design, which makes the zoom effect more precise and takes into account a large zoom range and cost-effectiveness.

[0028] In addition, since the cameras 17 are distributed in a triangular pattern equidistantly around a circle, the cameras 17 installed at equal intervals can focus on recording images in one direction and angle, so as to realize full-angle maintenance records in the boiler, thereby improving the overall maintenance accuracy of the boiler anti-wear and explosion-proof maintenance device. The electromagnetic ultrasonic module 16 can detect the wall thickness of the pipe in the boiler. Specifically, the electromagnetic ultrasonic module 16 uses the electromagnetic induction principle to induce eddy current signals on the material being tested through the induction coil inside the electromagnetic ultrasonic module 16, and obtains changes in the electromagnetic properties of the material surface. Then, using ultrasonic technology, the propagation speed and time of ultrasonic waves are measured to obtain the sound speed information inside the material. Finally, the measurement results of electromagnetic induction and ultrasonic technology are comprehensively analyzed to obtain the thickness information of the material. The camera 17 and the electromagnetic ultrasonic module 16 will uniformly transmit the maintenance data and images to the background for recording and maintenance.

[0029] The electromagnetic ultrasonic module 16 with model number MHT300 is a professional electromagnetic ultrasonic thickness detection module with high lift-off non-contact detection, open secondary development interface, support for multi-channel independent detection, and can be freely equipped with third-party automation equipment such as crawlers and drones to achieve thickness corrosion detection of pipelines, steel plates and boilers.

[0030] Furthermore, a group of limit slide rods 7 are fixedly connected to the symmetrical sides of the upper surface of the base plate 1, and a groove 6 for sliding outside the limit slide rod 7 is opened through the surface of the displacement sleeve 5, and the threaded rod 4 and the end of the limit slide rod 7 away from the base plate 1 are jointly connected to the limit top plate 8.

[0031] It is worth noting that when the displacement sleeve 5 moves up and down, the notch of the displacement sleeve 5 slides on the outer rod surface of the limiting slide rod 7 to ensure the stability of the height adjustment, and the limiting top plate 8 is used for limiting.

[0032] Example 2: Based on the above example, please refer to Figures 1 to 3 The upper end of the outer shell 11 is integrally connected to the upper shell 12, and an electric push rod 13 is fixedly installed in the upper shell 12. The push rod part of the electric push rod 13 is fixedly connected to an inner slide rod 14, and the inner slide rod 14 is fixedly connected to one side surface of the fixing plate 15, and the inner slide rod 14 slides inside the outer shell 11.

[0033] More specifically, when the camera 17 and the electromagnetic ultrasonic module 16 enter the boiler for maintenance, the operator can start the electric push rod 13 in the upper cylinder shell 12 according to the length inside the boiler. The push rod part of the electric push rod 13 pushes the inner slide rod 14 to slide a corresponding length in the outer cylinder 11, and cooperates with the camera 17 and the electromagnetic ultrasonic module 16 to complete the maintenance.

[0034] Working principle: The boiler anti-wear and explosion-proof maintenance device includes the following steps when in use:

[0035] 1. Firmly fix the bottom plate 1 through the threaded holes 2;

[0036] 2. Start the first motor 3. The output shaft of the first motor 3 drives the threaded rod 4 to rotate accordingly. The displacement sleeve 5 is threadedly sleeved on the outside of the threaded rod 4, thereby adjusting the inlet height of the boiler to be inspected;

[0037] 3. Start the second motor 9. The output shaft of the second motor 9 drives the collar 10 and the outer shell 11 to rotate at a corresponding angle until the electromagnetic ultrasonic module 16 and the camera 17 on the fixed plate 15 rotate to the maintenance inlet of the boiler, thereby meeting the maintenance of boilers at different inlet angles and improving the practicality of the boiler anti-wear and explosion-proof maintenance device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
