Detailed Implementation

[0023] The embodiments of the technical solution of this application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and the foregoing description of the accompanying drawings are intended to cover non-exclusive inclusion.

Figure 6 This is a partial structural diagram of the lower base provided in an embodiment of this application. Figure 7 for Figure 6Enlarged view at point B. The power fiber optic sensing device 100 includes a sensor body 110 and an adjustable base 120. The sensor body 110 has a built-in fiber Bragg grating demodulator. Both the fiber Bragg grating demodulator and the sensor body 110 can be purchased commercially. Since the fiber Bragg grating demodulator and the sensor body 110 are prior art and not the core inventive point of this application, they will not be described in detail here. A level bubble 111 is provided on the top of the sensor body 110. The fiber Bragg grating demodulator is parallel to the top end face of the sensor body 110. The level bubble 111 is used by the operator to determine whether the sensor body 110 is in a horizontal state. Since the fiber Bragg grating demodulator is built into the sensor body 110 and is parallel to the top surface of the sensor body 110, when the level bubble 111 at the top of the sensor body 110 reaches the predetermined position, both the fiber Bragg grating demodulator and the sensor body 110 will reach a horizontal position. The adjustable base 120 includes an upper base 121 and a lower base 122, which are connected by multiple height adjustment knobs 123 (the height adjustment knobs 123 can be set with reference to existing technologies such as foot screws). After installation, the position of the lower base 122 will be fixed. By simultaneously adjusting each height adjustment knob 123, the upper base 121 can be raised or lowered, or one or more height adjustment knobs 123 can be adjusted individually to tilt the upper base 121 in different directions. Furthermore, the tilting of the lower base 121 will cause the sensor body 110 on top of it to tilt, thereby completing the adjustment of the horizontal state of the sensor body 110. The sensor body 110 is connected to the top of the upper base 121 via a rotating component 130. The rotating component 130 drives the sensor body 110 to rotate, thereby completing multi-directional working tasks. An annular protective barrier 140 is fitted around the outer periphery of the upper base 121. During operation, the protective barrier 140 lowers and covers the gap between the upper base 121 and the lower base 122 to prevent wind and rain erosion, thus providing some protection for the various height adjustment knobs 123. Connecting seats 141 are respectively provided on opposite sides of the protective barrier 140. A support rod 142 is hinged to the connecting seat 141. A threaded groove is provided in the middle of the support rod 142, and a nut 143 is screwed onto it. When the protective barrier 140 is in the lowered state and covers the upper base 121 and the lower base 122, the nut can be tightened so that the nut 143 tightly abuts against the lower part of the support seat 150, thereby limiting and fixing the protective barrier 140.The bottom end of the support rod 142 is connected to the support foot 144. The lower base 122 is provided with a support seat 150 opposite to the connecting seat 141. The outer wall of the support seat 150 is provided with a U-shaped groove 151 for the support rod 142 to slide into laterally. The top of the support seat 150 is provided with a bearing groove 152 corresponding to the support foot 144. When the protective fence 140 is in the top raised position, the support rod 142 can be rotated so that the support foot 144 at the bottom is supported on the bearing groove 152. At this time, the entire protective fence 140 will be raised to the top and fixed.

[0025] As can be seen from the above, in the embodiment of this application, during the installation process of this device, the lower base 122 is first installed on the measurement reference surface, and then the horizontal position of the sensor body 110 is adjusted by adjusting one or more height adjustment knobs 123 and observing the level bubble 111 at the top of the sensor body 110, so that the components inside the sensor body 110, including the fiber optic demodulator, reach the optimal operating state. After the equipment is adjusted, the operator holds the support rods 142 on both sides with both hands, with the upper side of the index finger against the bottom of the connecting seat 141, and pushes the protective enclosure 140 upwards. The operator then rotates the support rods 142 in opposite directions, dragging the protective enclosure 140 down until the connecting seat 141 is against the top of the support seat 150. After sliding the support rods 142 into the U-shaped groove 151, the operator tightens the nuts so that the nuts 143 are against the bottom of the support seat 150 to complete the fixation. When the height adjustment knob 123 needs to be adjusted again, the operator can loosen the nuts 143 and drag the two support rods 142 to rotate to both sides to disengage them from the U-shaped groove 151. Then, the operator raises the protective enclosure 140, causing the support rods 142 to rotate again, and the support feet 144 are placed in the bearing groove 152. At this time, the protective enclosure 140 will be lifted and fixed, and the operator can then operate the height adjustment knob 123.

[0026] As can be seen from the above, in this embodiment, by setting up an upper base 121, a lower base 122, a sensor body 110, and a height adjustment knob 123, the device's level can be adjusted after installation using the height adjustment knob 123. This reduces the device's requirements for the flatness of the installation environment, extends the device's application scenarios, and relatively reduces or eliminates the need for leveling the road surface and pouring the base before installation. In this application, by setting up a connecting seat 141, a support rod 142, a protective barrier 140, and a bearing groove 152, the protective barrier 140 is in a lowered state when the device is in use, protecting the height adjustment knobs 123. When adjustment is needed, the protective barrier 140 can be easily and quickly raised and fixed without affecting the continued use of the device.

[0027] In some embodiments, the rotating component 130 includes a support platform 131 disposed within the cavity of the upper base 121. A rotating shaft is vertically disposed on the support platform 131, and a drive motor 132 is drivenly connected to the rotating shaft. The top end of the rotating shaft is connected to a support frame 134 via a rotating support 133, and the top of the support frame 134 loads the sensor body 110. In this embodiment, during operation, the drive motor 132 can drive the rotating shaft to rotate, which in turn drives the rotating support 133 and the support frame 134 at its top to rotate, further driving the sensor body 110 at the top of the support frame 134 to rotate and complete multi-angle operation tasks. The arrangement of the above-mentioned components can further improve the stability of the sensor body 110 during rotation.

[0028] In some embodiments, the support frame 134 is cross-shaped, and the end of the support frame 134 bends upward to form a connection end 134a for connecting with the sensor body 110. In this embodiment, through the above-described arrangement, the cross-shaped support frame 134 can evenly and extensively support the bottom of the sensor body 110, providing stable support. The support frame 134 can be made entirely of stainless steel to avoid problems such as tilting of the sensor body 110 due to insufficient support strength.

[0029] In some embodiments, a magnetic suction component 152a is provided on the inner sidewall of the support groove 152, and the support foot 144 is made of a ferromagnetic material. In this embodiment, with the above-described configuration, when the operator lifts the protective barrier 140 to a high point, the magnetic suction component 152a will attract the support foot 144, thereby allowing the support foot 144 to be attracted by the magnetic suction component 152a after it hangs vertically under gravity, adaptively adjusting its position and ultimately supporting it above the support groove 152.

[0030] In some embodiments, the bottom of the support foot 144 is connected to an anti-slip pad 144a. In this embodiment, by providing the anti-slip pad 144a, the protective support foot 144 can be prevented from slipping off the bearing groove 152, thus preventing the protective barrier 140 from losing its support.

[0031] In some embodiments, a heat dissipation grille 112 is provided on one side of the sensor body 110, and a plurality of doors 113 are provided on the other side of the sensor body 110 located at the heat dissipation grille 112. In this embodiment, the sensor adopts a side-opening door type instead of a top cover, which can avoid the problem of the top cover tilting after frequent opening and closing, which would further cause display errors of the level bubble 111.

[0032] In some embodiments, flat first support feet 122a are formed at the four bottom corners of the lower base 122, and second support feet 122b are fixedly connected to the four outer corners of the lower base 122. The bottoms of the first support feet 122a and the second support feet 122b are at the same horizontal height. In this embodiment, by adding second support feet 122b, during use, it is only necessary for the second support foot 122b on one side and the first support foot 122a on the opposite side to be stably supported on the ground, or for the second support feet 122b on both sides to be stably connected to the ground, or for the first support feet 122a on both sides to be stably connected to the ground. Any one of these three conditions can achieve a stable connection to the device.
