Description

Technical Field

[0001] The utility model belongs to the technical field of submarine cable monitoring, and in particular relates to a submarine cable status monitoring device. Background Art

[0002] Fiber optic sensing technology is a new sensing technology that has developed along with the optical fiber and fiber optic communication technology. It is the fastest-growing high-tech application technology in the world since the mid-1970s. Fiber optic sensors are essentially different from electrical-based sensors. Fiber optic sensors use light as a carrier of sensitive information and optical fiber as a medium for transmitting sensitive information. Submarine cables are located in the seawater.

[0003] Please refer to the patent document with application number 202021452574.X, which discloses an optical fiber temperature measurement system for submarine cable monitoring, including a temperature measuring host. Ventilation holes are provided at both ends of the temperature measuring host. A fan bracket is fixedly connected to the inner side of the vent. A fan is fixedly installed at one end of the fan bracket. The utility model has a scientific and reasonable structure and is safe and convenient to use. It is provided with a temperature measuring host, a vent, a fan bracket, a fan, a sliding groove, a filter bracket, a pull ring, a magnet bar and a filter. When the temperature measuring system starts working, the fan starts to rotate and sucks external air into the temperature measuring host from the vent on the side where the fan is not installed. When the air is filtered, dust particles and water vapor in the air are adsorbed, so that dry and clean air enters the interior of the temperature measuring host and is discharged from another vent through the fan after absorbing heat.

[0004] In the above-mentioned prior art solutions, although the filter is provided to dry and purify the air, thereby dissipating heat inside the temperature measuring host, the filter cannot completely filter dust and water vapor, and there is still a risk of components being affected.

[0027] 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.

[0028] The utility model provides Figure 1-Figure 4 A submarine cable status monitoring device shown in the figure comprises a protection box 1, a monitoring device body 2 and a heat dissipation cover 3.

[0029] The protection box 1 is used to store the monitoring device body 2 to provide protection for the monitoring device body 2. Four bases 11 distributed in a matrix are fixed to the bottom of the protection box 1. The four bases 11 can be evenly stressed to provide stable protection for the protection box 1.

[0030] The monitoring device body 2 is installed in the protection box 1, and a heat pipe 21 is fixed on the inner wall of the monitoring device body 2, which is circumferentially surrounded, and both ends of the heat pipe 21 extend to the outer wall of the monitoring device body 2. The heat pipe 21 is spirally surrounded and has a long length, which can fully absorb the heat of the protection box 1. The channel in the heat pipe 21 can allow air to circulate, and the air is used as a cooling medium.

[0031] In order to further provide protection for the monitoring device body 2, the top and bottom walls of the monitoring device body 2 are fixed with a plurality of buffer springs 1-4 through hinge seats 24, and the two ends of the buffer springs 1-4 are respectively hinged to the monitoring device body 2 and the inner wall of the protection box 1; the side walls of the monitoring device body 2 are fixed with a plurality of buffer springs 2-5, and the two ends of the buffer springs 2-5 are respectively hinged to the monitoring device body 2 and the inner wall of the protection box 1. The monitoring device body 2 is connected to the inner wall of the protection box 1 through the buffer springs 1-4 and 2-5, and can be suspended in the protection box 1. The buffer springs 1-4 and 2-5 provide vertical and lateral shock absorption, so that the monitoring device body 2 has good anti-collision performance, providing more comprehensive protection for the monitoring device body 2.

[0032] There are two heat dissipation covers 3, which are respectively located at the top and bottom of the protective box 1. In other embodiments, they can also be arranged on the side of the protective box 1. Specifically, the heat dissipation cover 3 is embedded and fixed on the box wall of the protective box 1, and has multiple air outlets 31 and an air inlet 32 ​​facing the outside of the protective box 1. The heat dissipation cover 3 has an air outlet cavity connected to the air outlets 31 and an air inlet cavity connected to the air inlet 32; each air outlet 31 is installed with an exhaust fan 311; two heat pipes 21 are connected to the air inlet cavity and the air outlet cavity respectively through the air pipe 33. Each exhaust fan 311 is configured to be started and shut down individually. The higher the number of exhaust fans 311 that are started, the higher the heat dissipation efficiency. The user can select the number of exhaust fans 311 that need to be started according to specific needs and the working conditions of the monitoring device body 2, which can effectively save energy while ensuring reasonable heat dissipation efficiency. After being started, the exhaust fan 311 can draw the air in the heat pipe 21 from the air pipe 33 and discharge it from the air outlet 31. The external air enters from the air inlet 32 ​​and then flows into the heat pipe 21, thereby realizing circulating heat dissipation.

[0033] For further information, see Figure 2 , Figure 3 and Figure 4 , a plurality of inner balls 22 are fixed on the heat conducting tube 21; a coolant is stored in the inner balls 22; and a liquid infusion tube 23 is connected between the inner balls 22. The liquid infusion tube 23 is connected to a micro pump 231. The micro pump 231 can drive the coolant to circulate between the inner balls 22 through the liquid infusion tube 23, thereby quickly absorbing heat and evenly dispersing the heat to prevent heat concentration, which is safer.

[0034] It should be added that two symmetrically distributed lifting handles 12 are fixed on the top of the protection box 1 , and the operator can move the protection box 1 by the lifting handles 12 .

[0035] Also, see Figure 1In order to reduce the external impurities from entering the heat pipe 21, a partition net 312 is installed inside the air outlet 31, and a dustproof net 321 is installed inside the air inlet 32. The partition net 312 and the dustproof net 321 can isolate external impurities and dust to ensure the ventilation efficiency in the heat pipe 21.

[0036] Working principle: In the utility model, a submarine cable status monitoring device is used. When in use, the monitoring device body 2 is connected to the inner wall of the protective box 1 through the buffer spring 1 4 and the buffer spring 2 5, and can be suspended in the protective box 1. The buffer spring 1 4 and the buffer spring 2 5 provide vertical and lateral shock absorption, so that the monitoring device body 2 has good anti-collision performance, providing more comprehensive protection for the monitoring device body 2. The user can select the number of exhaust fans 311 to be started according to specific needs and the working conditions of the monitoring device body 2, which can effectively save energy while ensuring reasonable heat dissipation efficiency. After starting, the exhaust fan 311 can draw the air in the heat pipe 21 from the air pipe 33 and discharge it from the air outlet 31. The external air enters from the air inlet 32 ​​and then flows into the heat pipe 21, thereby realizing circulating heat dissipation.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
