[0019] 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.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1-Figure 3The utility model discloses a magnetic reinforcement vibration monitoring device for a cable bridge, including a reinforcement plate 3 detachably connected to a cable bridge 5, a detection component is fixedly connected to the top surface of the reinforcement plate 3, magnetic components are symmetrically arranged on both sides of the top surface of the reinforcement plate 3, and the magnetic components are arranged around the detection component. The detection component includes an acceleration sensor 1, and the acceleration sensor 1 is electrically connected to a data transmission radio station 2. The acceleration sensor 1 and the data transmission radio station 2 are fixedly connected to the top surface of the reinforcement plate 3.

[0022] The utility model fixes the acceleration sensor 1 and the digital transmission station 2 on the reinforcement plate 3, and can quickly and conveniently install the reinforcement plate 3 on the cable tray 5 through a magnetic suction component, so that the monitoring component can effectively record the vibration acceleration and vibration frequency changes of the cable tray 5.

[0023] The acceleration sensor 1 selects a suitable high-precision acceleration sensor, which is protected by a sealed silicon cap to reduce the impact of the working environment; and the vibration of the cable tray 5 is accurately monitored and data collected through the high-precision acceleration sensor.

[0024] The data transmission radio 2 may also be referred to as a "wireless data transmission radio" or a "wireless data transmission module". It is a prior art and will not be described in detail here.

[0025] In order to optimize maintenance and reduce the workload of operation and maintenance personnel, NB-IOT (2g signal) communication method is used for data transmission. By adopting low-power and wide-coverage signal communication method for data transmission, the effect of taking into account both functional use and energy saving is achieved.

[0026] By fixing the acceleration sensor 1 and the digital transmission station 2 on the top surface of the reinforcement plate 3, it is convenient for quantitative production and use.

[0027] According to a further optimization scheme, both ends of the reinforcement plate 3 extending out of the cable tray 5 are fixedly connected with connecting plates 7, and one end of the connecting plate 7 away from the reinforcement plate 3 is fixedly connected with a limiting plate 6, and the limiting plate 6 is detachably connected to the bottom surface of the cable tray 5.

[0028] According to a further optimized solution, the two connecting plates 7 are arranged to be inclined relative to each other.

[0029] To further optimize the solution, the connecting plate 7 is made of tough material.

[0030] In a further optimized solution, the distance between the ends of the two connecting plates 7 away from the reinforcing plate 3 is smaller than the distance between the ends of the two connecting plates 7 close to the reinforcing plate 3 .

[0031] After the connecting plates 7 are installed on the cable tray 5, the toughness of the connecting plates 7 enables the opposite sides of the two connecting plates 7 to tightly abut against the outer wall of the cable tray 5. At the same time, the limiting plates 6 abut against the bottom surface of the cable tray 5, so that the reinforcing plates 3 can tightly abut against the top surface of the cable tray 5.

[0032] In order to prevent the reinforcement plate 3 from moving due to vibration during vibration monitoring, positioning columns are fixedly connected to the opposite sides of the two connecting plates 7. The positioning columns are detachably connected with positioning holes. The positioning holes are opened on the side walls of the cable tray 5. When the connecting plates 7 are tightly abutted against the side walls of the cable tray 5, the positioning columns are inserted into the positioning holes, so that the position of the reinforcement plate 3 on the cable tray 5 will not be affected by the vibration of the cable tray 5.

[0033] According to a further optimized solution, the magnetic attraction component includes a plurality of magnetic attraction buckles 4 , and the plurality of magnetic attraction buckles 4 are embedded in the top surface of the reinforcement plate 3 .

[0034] According to a further optimized solution, the magnetic buckle 4 is magnetically connected to the top surface of the cable tray 5 .

[0035] According to a further optimization scheme, a plurality of magnetic buckles 4 on the same side of the top surface of the reinforcing plate 3 are arranged at equal intervals.

[0036] By magnetically attracting the magnetic buckle 4 to the top surface of the cable tray 5, the reinforcement plate 3 can be positioned on the cable tray 5 when the cable tray 5 vibrates slightly. Compared with the traditional method of sticking sensors, the construction intensity is reduced and the error influence that may be caused by construction is reduced.

[0037] Working process: After determining the position for installing the reinforcement plate 3 on the cable tray 5, pry open the two connecting plates 7 so that the two connecting plates 7 are respectively on both sides of the cable tray 5, and release the two connecting plates 7. At this time, the opposite sides of the two connecting plates 7 are tightly in contact with the outer wall of the cable tray 5, and the limit plate 6 is tightly in contact with the bottom surface of the cable tray 5. At the same time, the magnetic buckle 4 is magnetically connected to the top surface of the cable tray 5, so that the reinforcement plate 3, the connecting plate 7, and the limit plate 6 can be wrapped and fitted on the cable tray 5, and the vibration data can be recorded without affecting the normal use function of the cable tray 5.

[0038] When the cable tray 5 vibrates slightly, the acceleration sensor 1 transmits data to the data transmission station 2, and the data transmission station 2 uploads the monitored data to the terminal.

[0039] When severe vibration occurs, the magnetic buckle 4, connecting plate 7 and limit plate 6 are wrapped around the periphery of the cable tray 5 to provide reinforcement and stability. At the same time, the positioning column is inserted into the positioning hole to prevent the reinforcement plate 3 from being displaced due to vibration, thereby effectively improving the accuracy of data collected by the acceleration sensor 1.

[0041] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
