Description

[0002] There are many high-pressure gas pipes in power plant equipment, and it is crucial to ensure the effective sealing of important parts such as flange connections and switches. Usually, the leak detection method for high-pressure gas pipes is to spray leak detection agents on important parts to observe whether large bubbles are generated. If large bubbles are generated, the flange is leaking. If no large bubbles are generated, the flange is well sealed. In actual production, many flanges, switches, etc. are located at low or high positions, and the lighting is insufficient. During the gas leak detection process, there are many blind spots and dead angles, and there is mutual interference between certain equipment. It is impossible to observe 360° without dead angles to detect whether there are bubbles in the flange seal, which is not conducive to timely detection of leakage, inspection and maintenance, resulting in frequent startup of the booster pump and increased power loss.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1, reference Figure 1 - Figure 4, which is the first embodiment of the present invention, provides a sealing leakage detection auxiliary device, which includes a bearing unit 100, including a first column 101, and a second column 105 arranged on the first column 101; a rotating unit 200, including a rotating motor 201 arranged on the second column 105, and an arc plate 203 arranged on one side of the connecting socket 202; and a detection unit 300, including a three-axis motor 301 arranged in the arc plate 203, a rotating gear 302 arranged on the three-axis motor 301, an information processor 303 arranged on one side of the three-axis motor 301, and a detection head 306 arranged on one side of the information processor 303. The angle between the extension lines of the planes where the two ends of the arc plate are located is set to angle a. By setting the angle size of angle a, the detection range of the arc plate 203 is controlled, so that the arc plate 203 can meet the detection of flange pipes of most sizes, thereby increasing the applicability and application range of the device.

[0029] The size of the flange pipe to be inspected is set to remain unchanged, so that the radius of the flange pipe is equal to the radius of the arc plate 203. At this time, the detection range of the detection ring is as shown in Table 1.

[0030] At the same time, the detection range of the detection unit 300 in the arc plate 203 can be determined by setting the angles at both ends. The radius of the arc plate 203 is set to the arc plate radius R, and the angle range is from θ1 to θ2 (θ1 and θ2 are both between 0° and 180°), then the detection range of the detection unit 300 can be calculated as follows:

[0031] Angle range: θ1 to θ2.

[0032] Arc length: R×(θ2-θ1) / 180°×π.

[0033] Area: R2×(θ2-θ1) / 360°×π.

[0034] The detection unit 300 rotates inside the arc plate 203, and the detection unit 300 has a certain detection range, and the detection range is an angle 3c.

[0035]

[0036] The above data are valid only when the radius of the arc plate 203 is equal to the radius of the flange pipe.

[0037] When the radius of the curved plate 203 is larger than the radius of the flange pipe, the detection range of the curved plate 203 will be larger;

[0038] When the radius of the arc plate 203 is smaller than the radius of the flange tube, the arc plate 203 cannot be wrapped around the outside of the flange tube, causing the edges at both ends of the arc plate 203 to fit together with the flange tube, making it impossible for the detection unit 300 to rotate over, thereby reducing the detection range of the arc plate 203.

[0039] During use, since the size of the flange pipe cannot be controlled, while the size of the arc plate 203 is fixed, according to the above data, the angles at both ends of the arc plate 203 need to be less than 180 and greater than 90°. At the same time, according to the above data, when the angles at both ends of the arc plate 203 are between 120°-135°, the detection range of the arc plate 203 is less than one-third of the surface of the flange pipe, plus the detection range of the detection unit 300 located at the edges of the two ends of the arc plate 203, the angles at both ends of the arc plate 203 are limited to between 120°-135°, which can meet the detection of most flange pipes. At this time, the staff holds the No. 1 column 101 so that the rotating unit 200 and the detection unit 300 at the top of the column surround the outside of the flange pipe, and the staff rotates around the flange pipe, so that the detection unit 300 inside the arc plate 203 surrounds the flange pipe for detection, and then the flange pipe whose radius is greater than the radius of the arc plate 203 can be detected, thereby increasing the scope of application of the device.

[0040] Example 2, reference Figure 1 - Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: an electric push rod 304 is provided on the information processor 303, a connecting rod 305 is provided on the electric push rod 304, a hinge 308 is provided on the detection head 306, a detection component 309 is provided at one end of the hinge 308, and a fill light 307 is provided around the detection head 306. The detection head 306 shoots the situation of the flange tube detection area, and the fill light 307 is used to fill it with light, so that the information processor 303 calculates the diameter of the dense bubbles in the image according to the shooting situation of the detection head 306, and transmits the maximum value thereof to the display screen 402. At the same time, the display screen 402 can generate an alarm signal by setting the bubble diameter. If the maximum diameter of the bubble exceeds 10 mm, an alarm signal is sent to remind the staff that the leakage of the flange tube here is serious and needs to be repaired and replaced in time.

[0041] Compared with Example 1, further, the number of detection components 309 is two groups, and the two groups of detection components 309 are located on the upper and lower sides of the detection head 306, the upper surface of the information processor is set as the X-axis, the extension line of the X-axis in the vertical direction is set as the Y-axis, and the angle between the plane where the detection components are located and the X-axis is set to angle b; the upper surface of the information processor 303 is set as the X-axis, the line segment extending upward in the vertical direction is set as the Y-axis, the angle between the vertical direction of the detection component 309 and the X-axis is angle b, and the angle between the electric push rod 304 and the X-axis is The angle is d. When the electric push rod 304 moves to the rightmost side, the detection component 309 and the top of the information processor 303 are parallel to each other. When the electric push rod 304 moves to the leftmost side, the angle between the detection component 309 and the top of the detection head 306 is 30°, so that the range of the angle b is between 0° and 150°. The electric push rod 304 is moved on both sides of the information processor 303 to adjust the size of the angle b and the detection range of the detection component 309, thereby improving the overall detection range of the device and the detection efficiency of the staff.

[0042] During use, according to the direction and size of the flange pipe, the electric push rod 304 is controlled by the three-axis motor 301 to move left and right on the information processor 303, and the size of the angle 4d is adjusted, and then the size of the angle 2b is adjusted, so that the detection component 309 rotates left and right around the hinge 308, thereby adjusting the detection range of the detection component 309 above the detection head 306. Similarly, the detection component 309 below the detection head 306 rotates around the hinge 308 at its top, and then the two groups of detection components 309 are used to simultaneously shoot on both sides of the detection head 306, thereby improving the overall detection range of the device, while improving the detection efficiency of the staff and reducing the labor intensity of the staff; at the same time The staff determines whether it is necessary to fold the two sets of detection components 309 on both sides of the detection head 306 according to the conditions around the flange pipe to be inspected and the equipment, so as to facilitate the arc plate 203 to extend between the flange pipe and the wall or equipment, and then enable 406 to shoot and detect the blind spots and dead angles of the flange pipe. At this time, the fill lights 307 around the detection head 306 can be turned on to fill in the shooting area, so that the detection head 306 can shoot more accurately and clearly, thereby improving the accuracy of the information processor 303 in processing the shooting information of the detection head 306. Then the staff determines whether it is necessary to replace and repair the flange pipe at this location according to the information displayed on the display screen 402, which increases the comfort of the staff.

[0043] The remaining structures are the same as those of Example 1.

[0044] Example 3, reference Figure 1 - Figure 7, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a power base plate 102 is provided at the bottom of the No. 1 column 101, a battery 103 located on the power base plate 102 is provided inside the No. 1 column 101, a power connector 104 is provided inside the No. 1 column 101, a power connection line 106 corresponding to the power connector 104 is provided inside the No. 2 column 105, and the number of No. 2 columns 105 is at least two groups. Through multiple groups of No. 2 columns 105, it is convenient for staff to assemble them arbitrarily, so as to detect leaks of flange pipes at different heights, thereby increasing the applicability of the device.

[0045] Compared with Example 2, further, the observation unit 400 includes a fixing ring 401 arranged on the No. 1 column 101, a display screen 402 arranged on one side of the fixing ring 401, a connecting plug 403 arranged on one side of the display screen 402, and a control panel 404 arranged on the display screen 402. The rotating motor 201 and the three-axis motor 301 can be controlled by the control panel 404, so that the rotating motor 201 drives the arc plate 203 to rotate, the three-axis motor 301 rotates in the arc plate 203, and the three-axis motor 301 drives the electric push rod 304 to move. The shooting status and data of the detection head 306 and the detection component 309 are displayed on the display screen 402, which makes it convenient for the staff to judge whether the flange pipe here needs to be inspected and replaced, thereby increasing the comfort of the staff.

[0046] During use, the staff selects an appropriate number of No. 2 columns 105 according to the position and height of the flange pipe to be detected, then connects multiple groups of No. 2 columns 105 together, and connects the power connection lines 106 inside them to each other, and then installs the rotating motor 201 on the top of the No. 2 column 105, and installs the No. 1 column 101 on the bottom of the No. 2 column 105, so that the device can start detection, which makes it easier for the device to detect flange pipes of different heights, thereby increasing the applicability of the device and the comfort of the staff;

[0047] When inspecting the vertical flange pipe, the staff holds the No. 1 column 101 and lifts the No. 2 column 105, and then gradually moves the top of the No. 2 column 105 to the flange pipe inspection area, and controls the rotating motor 201 and the three-axis motor 301 through the control panel 404 on the outside of the No. 1 column 101, so that the rotating motor 201 drives the arc plate 203 to rotate, the three-axis motor 301 rotates in the arc plate 203, and the three-axis motor 301 pushes the electric push rod 304 to move, thereby adjusting the inspection area of ​​the inspection components 309 on the upper and lower sides of the inspection head 306. At this time, the staff makes the inspection head 306 at one end of the three-axis motor 301 face the inspection area of ​​the flange pipe according to the position height of the flange pipe, and then judges whether there are any equipment or walls around the flange pipe that block the inspection according to the surrounding conditions of the flange pipe. At this time, the outer side of the arc plate 203 is close to the equipment or wall, and then the rotating gears 302 at the upper and lower ends of the three-axis motor 301 are controlled to rotate through the control panel 404 , thereby making the three-axis motor 301 rotate in the arc plate 203, and at this time, the fill light 307 around the detection head 306 is turned on to fill light on the outside of the flange tube, so as to facilitate the detection of the outside of the flange tube by the detection head 306 more clearly, thereby increasing the detection accuracy of the detection head 306, and then the detection head 306 shoots the situation on the outside of the flange tube and transmits it to the display screen 402. At this time, the information processor 303 calculates the diameter of the dense bubbles in the image according to the shooting situation of the detection head 306, and transmits the maximum value thereof to the display screen 402. At the same time, the display screen 402 can generate an alarm signal by setting the bubble diameter size. If the maximum diameter of the bubble exceeds 10mm, an alarm signal is sent to remind the staff that the leakage of the flange tube here is relatively serious and needs to be repaired and replaced in time. At the same time, the detection components 309 on the upper and lower sides of the detection head 306 supplement the edge of the leakage detection area of ​​the flange tube to further ensure the shooting accuracy of the detection head 306.

[0048] When inspecting the horizontal flange pipe, the control panel 404 on the outside of the first column 101 is used to control the rotating motor 201, so that the arc plate 203 at one end starts to rotate 90 degrees, so that the arc plate 203 and the flange pipe are perpendicular to each other, and the arc plate 203 is brought close to the flange pipe, so that the detection head 306 can shoot the monitoring area of ​​the flange pipe. At this time, according to the radius of the flange pipe, the electric push rod 304 is controlled by the three-axis motor 301 to move left and right above the information processor 303, so as to adjust the detection component 309 at one end of the connecting rod 305 and the top of the information processor 303. The size of the angle b is adjusted, and the detection component 309 is rotated to shoot the range of the flange tube with the hinge 308 as the origin. When the electric push rod 304 moves to the far right, the detection component 309 and the top of the information processor 303 are parallel to each other. When the electric push rod 304 moves to the far left, the angle between the detection component 309 and the top of the detection head 306 is 30°, so that the range of angle b is between 0° and 150°. Then, according to the radius of the flange tube, if the radius of the flange tube is smaller than the radius of the arc plate 203, the electric push rod is moved to the left. 304, that is, to increase the size of angle b, so that the detection head 306 and the detection components 309 at both ends rotate, and at the same time, the outer side of the flange pipe is leak-checked, thereby increasing the single detection range of the detection unit 300, thereby reducing the leak detection time of the staff on the flange pipe and improving the leak detection efficiency of the staff; if the radius of the flange pipe is greater than the radius of the arc plate 203, at this time, the electric push rod 304 is moved to the right, that is, the size of angle b is reduced, the detection range of the detection unit 300 is increased, and then the rotating gears 302 at both ends are controlled by the three-axis motor 301 to rotate on the arc plate 203 At the same time, the staff manually raises the second column 105, so that the arc plate 203 is above the flange pipe. At this time, the detection unit 300 moved to the top of the arc plate 203 can detect leaks on the top area of ​​the flange pipe. Similarly, the staff moves the detection unit 300 to the other side of the flange pipe for leak detection, thereby detecting leaks all around the flange pipe. The leak detection results are transmitted to the display screen 402, which makes it convenient for the staff to detect leaks on the flange pipe, thereby improving the work efficiency and comfort of the staff.

[0049] The remaining structure is the same as that of Example 2.
