Description

Technical Field

[0001] The utility model relates to the technical field of waterproofing, in particular to a waterproofing device for an on-site wound magnetic flux sensor. Background Art

[0002] Conventional magnetic flux sensors are used to measure the tension in bridge cables. The conventional structure is a through-type, but it is only applicable to scenarios where the cables have not yet been installed. For bridge facilities that have already been built, conventional magnetic flux sensors cannot be installed because the cables are anchored at both ends.

[0003] Therefore, a field-wound magnetic flux sensor was designed. Its basic structure is based on the traditional cylindrical through-hole structure, with the winding fixture and the metal protective cover cut in the middle to form two semicircular structures. However, there is a gap between the two semicircular structures. The field-wound magnetic flux sensor should not be exposed to water, so waterproof protection is required to ensure normal use. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a waterproof device for a field-wound magnetic flux sensor to address the problem of waterproof protection of the field-wound magnetic flux sensor in the prior art.

[0005] A waterproof device for a field-wound magnetic flux sensor comprises two protective shells arranged opposite to each other, the protective shells comprising an arc-shaped portion, two platform portions and two abutting portions, the two abutting portions being movably connected to opposite sides of the arc-shaped portion, the two protective shells being connected via the abutting portions, the inner sidewall of the arc-shaped portion being connected to the two platform portions, the two platform portions being located at opposite ends of the arc-shaped portion, one side of the platform portion being concave to form a first notch, a sealing strip being provided on the inner sidewall surrounding the first notch, and the two protective shells being used to enclose the field-wound magnetic flux sensor.

[0006] Beneficial effects of the utility model:

[0007] On the outer wall of the installed field-wound magnetic flux sensor, the two protective shells are brought close to each other, and the gap of the spliced ​​two protective shells is offset with the gap of the installed field-wound magnetic flux sensor. The two protective shells are connected by abutting parts, and the arc-shaped part fits the outer wall of the field-wound magnetic flux sensor. At this time, the platform part is located at the opposite ends of the field-wound magnetic flux sensor, and the first notch fits the bridge cable.

[0021] A waterproof device for field-wound magnetic flux sensors, such as Figures 1 to 2 As shown, it includes two protective shells 1 and two upper covers 2 arranged opposite to each other.

[0022] Specifically, such as Figures 1 to 3 As shown, the protective housing 1 includes an arcuate portion 11, two platform portions 12, and two abutting portions 13. The two abutting portions 13 are rotatably connected to opposite sides of the arcuate portion 11. The two protective housings 1 are connected by the abutting portions 13. The inner sidewall of the arcuate portion 11 connects to the two platform portions 12, which are located at opposite ends of the arcuate portion 11. The arcuate portion 11 is provided with a plurality of first through-holes 111, and the abutting portion 13 is provided with a plurality of first threaded through-holes 131. The plurality of first through-holes 111 and the plurality of first threaded through-holes 131 correspond in position. Two platform portions 12 are provided at opposite ends of the arcuate portion 11. One side of the platform portion 12 is recessed to form a first notch 121. The platform portion 12 is provided with a plurality of second threaded through-holes 123. A sealing strip 122 made of silicone is provided on the inner sidewall surrounding the first notch. A step 14 is provided between the platform portion 12 and the arcuate portion 11. The two protective housings 1 are used to enclose a field-wound magnetic flux sensor 4. The two protective shells 1 are fixedly connected by bolts passing through the first through hole 111 and the first threaded through hole 131 in turn. At this time, the two first notches 121 are in contact with the bridge cable 3, and the sealing strip 122 presses the bridge cable 3. The on-site wound magnetic flux sensor 4 is wrapped by the two protective shells 1. The gaps between the two protective shells 1 and the gaps between the on-site wound magnetic flux sensor 4 are installed in an offset manner to form a first waterproof layer above the two first notches 121.

[0023] Specifically, the upper cover 2 is detachably connected to the platform portion 12. The upper cover 2 is arc-shaped, and a plurality of third threaded through holes 21 are provided on the top surface of the upper cover 2. The plurality of second threaded through holes 123 correspond to the positions of the plurality of third threaded through holes 21. An extension portion 22 is provided along the bottom circumference of the upper cover 2, and the extension portion 22 is adapted to the step portion 14. A second notch 23 is provided on one side of the upper cover 2, and the second notch 23 is staggered with the position of the first notch 121. Bolts are passed through the second threaded through holes 123 and the third threaded through holes 21 in sequence to fix the two upper covers 2 to the two protective shells 1 respectively. At this time, the two second notches 23 are aligned with the bridge cables 3. It should be noted that by staggering the positions of the second notches 23 and the first notches 121, the position of the splicing gap is changed when the two upper covers 2 are fixedly connected, forming a staggered position with the splicing gap of the two protective shells 1. The extension portion 22 and the step portion 14 can be provided with a sealing ring to increase the sealing performance and form a second waterproof layer.

[0024] According to the utility model, on the outer wall of the installed field-wound magnetic flux sensor 4, the two protective shells 1 are brought close to each other, and the gap of the two protective shells 1 is offset with the gap of the installed field-wound magnetic flux sensor 4. The two protective shells 1 are connected by the abutment portion 13, and the arc portion 11 fits the outer wall of the field-wound magnetic flux sensor 4. At this time, the platform portion 12 is located at the opposite ends of the field-wound magnetic flux sensor 4, and the first notch 121 fits with the bridge cable 3. The sealing strip 122 is used to seal the gap after the two first notches 121 are connected. After the two upper covers 2 are fixed to the two protective shells 1, the second notch 23 fits with the bridge cable 3, and the gap of the two upper covers 2 and the gap of the two protective shells 1 are installed offset. The on-site wound magnetic flux sensor 4 is wrapped by two protective shells 1, and the spliced ​​gaps are staggered. Then, through the setting of the sealing strip 122 and the setting of the upper cover 2, the spliced ​​gaps of the two upper covers 2 and the spliced ​​gaps of the two protective shells 1 are staggered, thereby achieving effective waterproofing, simple structure and convenient connection.
