[0002] Bridge monitoring refers to monitoring and evaluating the condition of bridge structures, issuing early warning signals when bridges are in special climate and traffic conditions or when the bridge operation conditions are abnormally serious, and providing a basis and guidance for bridge maintenance and management decisions. However, bridge structural health monitoring is not only for structural status monitoring and evaluation, but its information feedback to structural design has a more far-reaching significance in that structural design methods and corresponding specifications and standards may be improved;

[0003] After checking the publication number: CN208948594U discloses a highway bridge monitoring and early warning device. This technology discloses "early warning control box, operation panel, display screen, buzzer, data processor, transmission line connector, storage box, transmission wire, stress sensing head. The utility model is provided with a storage box. When in use, the transmission wire at the outlet end is pulled outward, so that the transmission wire drives the reel to rotate counterclockwise on the bearing to perform the wire release operation. When the monitoring is completed and the reel is recovered, the turntable is rotated to drive the reel to rotate clockwise to reel the transmission wire onto the reel for recycling, so that the transmission wire can be pulled out when in use, and can be recycled into the storage box when not in use, effectively avoiding the damage caused by the exposed winding of the transmission wire, which can play a good protective role on the transmission wire, effectively prolong the service life of the transmission wire, and indirectly improve the accuracy of highway bridge monitoring and early warning, and ensure the safety of highway bridge construction".

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.

[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A highway bridge monitoring and early warning device comprises a monitoring box 1.

[0025] In this implementation scheme: the existing {public announcement number}: CN208948594U discloses a highway bridge monitoring and early warning device, and this patent discloses an operating panel. The monitoring box 1 in this application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the device is used to store the wire end, it is also necessary to store it manually, which leads to an extension of the construction time, thereby affecting the monitoring progress and being detrimental to the overall detection efficiency. At the same time, the device lacks a structure for positioning the wire end, which easily leads to the loosening of the wire end." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a connecting shaft 2 and a coil spring 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes a connecting shaft 2, a coil spring 3, a winding shaft 4, a winding bin 5, a positioning sleeve 6 and a screw sleeve 7 arranged on one side of the monitoring box 1, the inner surface of the monitoring box 1 is fixedly connected to the surface of one side of the connecting shaft 2, and the surface of the connecting shaft 2 is fixedly connected to one end of the coil spring 3, and the other end of the coil spring 3 is fixedly connected to the inner surface of the winding shaft 4, and at the same time, the winding shaft 4 and the winding bin 5 opened on the inner surface of the monitoring box 1 are rotationally connected, and a positioning sleeve 6 is also fixedly installed on one side of the surface of the monitoring box 1, and the surface of the positioning sleeve 6 is threadedly connected to the inner surface of the screw sleeve 7.

[0029] When the monitoring line is used up, the screw sleeve 7 and the positioning sleeve 6 are rotated in the reverse direction and the limit of the monitoring line is released. At this time, the coil spring 3 will release its elastic potential energy and drive the winding shaft 4 to rotate, so that the monitoring line located outside the monitoring box 1 can be automatically wound up.

[0030] Going further:

[0031] In an optional embodiment, the shape of the connecting shaft 2 is cylindrical, and the center of the circle where the connecting shaft 2 is located and the center of the circle where the winding shaft 4 is located are at the same point.

[0032] In this embodiment, the winding shaft 4 with the center of the connecting shaft 2 at the same point can make the winding shaft 4 rotate stably and effectively, which can provide a good working basis for the contraction and release of the monitoring line that plays a monitoring role.

[0033] Going further:

[0034] In an optional embodiment, the coil spring 3 is in a spiral shape.

[0035] In this embodiment: the spirally arranged coil spring 3 can generate a certain elastic potential energy through the force of the connecting shaft 2 and the coil shaft 4 when the coil shaft 4 rotates, thereby providing an auxiliary force for contraction when the monitoring line is stored.

[0036] Going further:

[0037] In an optional embodiment, the winding shaft 4 is in the shape of a circular ring, and the diameter of the winding shaft 4 is smaller than the diameter of the winding bin 5 .

[0038] In this embodiment: the winding shaft 4 with a circular shape and a diameter smaller than the winding bin 5 can allow the monitoring line to be wound around the surface of the winding shaft 4, so that the monitoring line can be well stored, and the winding shaft 4 with a diameter larger than the winding bin 5 can provide a stable space for the rotation of the winding shaft 4.

[0039] Going further:

[0040] In an optional embodiment, the winding bin 5 is opened in a “P” shape inside the monitoring box 1 , and the winding bin 5 is communicated with the external space of the monitoring box 1 .

[0041] In this embodiment, the "P"-shaped winding bin 5 can stably accommodate the connecting shaft 2, the coil spring 3 and the winding shaft 4 inside the monitoring box 1, and at the same time, the monitoring line wound on the surface of the winding shaft 4 can be extended to the outside of the monitoring box 1 through the winding bin 5.

[0042] Going further:

[0043] In an optional embodiment, rectangular grooves are formed at equal angles on the surface of the positioning sleeve 6 .

[0044] In this embodiment, the rectangular groove on the surface of the positioning sleeve 6 can drive the positioning sleeve 6 to contract when the positioning sleeve 6 and the screw sleeve 7 rotate, so that the monitoring line can be tightened by the positioning sleeve 6 to fix its length at the current state.

[0045] When the monitoring line is used up, the screw sleeve 7 and the positioning sleeve 6 are rotated in the reverse direction and the limit of the monitoring line is released. At this time, the coil spring 3 will release its elastic potential energy and drive the winding shaft 4 to rotate, so that the monitoring line located outside the monitoring box 1 can be automatically wound up.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
