DETAILED DESCRIPTION

[0019] Reference Figure 1 to Figure 2 An embodiment of a device for monitoring water accumulation in an optical cable well according to the present invention is further described.

[0020] A floor-standing optical cable surplus box comprises an outer box body 1 and an inner box body 2 located inside the outer box body 1 for storing the surplus optical cable, the inner box body 2 is provided with a nine-axis sensor 10 and a wireless signal transmission device 9 electrically connected to the nine-axis sensor 10, a plurality of support columns 4 are provided inside the outer box body 1, the inner box body 2 is suspended in the outer box body 1 through the support columns 4, a drainage channel 3 is formed between the side walls and the bottom wall of the inner box body 2 and the outer box body 1, an inner drainage hole 21 for discharging the accumulated water in the inner box body 2 is provided on the bottom wall of the inner box body 2, a drainage plate 5 for opening and closing the inner drainage hole 21 and a buoyancy component 6 for pushing the drainage plate 5 upward to close the inner drainage hole 21 are provided in the drainage channel 3. The present invention provides an inner box body 2 and an outer box body 1 so that the optical cable surplus has a double-layer structure for waterproof storage. The drainage hole can discharge rainwater entering the inner box body 2 to the drainage channel 3 formed by the inner box body 2 and the outer box body 1. At the same time, the drainage plate 5 and the buoyancy component 6 effectively prevent the rainwater entering the drainage channel 3 through the outer box body 1 from flowing back into the inner box body 2 through the drainage hole, thereby preventing the optical cable surplus from being soaked and damaged by rainwater due to water accumulation in the optical cable surplus box during heavy rainfall.

[0021] Embodiment 1:

[0022] A floor-standing optical cable surplus cable box comprises an outer box body 1 and an inner box body 2 located inside the outer box body 1 for storing the optical cable surplus cable, a nine-axis sensor 10 and a wireless signal transmission device 9 electrically connected to the nine-axis sensor 10 are arranged on the inner box body 2, a plurality of support columns 4 are arranged inside the outer box body 1, the inner box body 2 is suspended in the outer box body 1 through the support columns 4, a drainage channel 3 is formed between the inner box body 2 and the side wall and the bottom wall of the outer box body 1, an inner drainage hole 21 for draining the accumulated water in the inner box body 2 is arranged on the bottom wall of the inner box body 2, a drainage board 5 for opening and closing the inner drainage hole 21 and a buoyancy component 6 for pushing the drainage board 5 upward to close the inner drainage hole 21 are arranged in the drainage channel 3. The outer box body 1 comprises an outer box body and an outer box door covering the outer box body, and the inner box body 2 comprises an inner box body and an inner box door covering the inner box body.

[0023] The present invention provides an inner box 2 and an outer box 1 so that the optical cable surplus cable has a double-layer structure for waterproof storage. The drainage hole can discharge rainwater entering the inner box 2 to the drainage channel 3 formed by the inner box 2 and the outer box 1. At the same time, the drainage board 5 and the buoyancy component 6 effectively prevent the rainwater entering the drainage channel 3 through the outer box 1 from flowing back into the inner box 2 through the drainage hole, thereby preventing the optical cable surplus cable from being soaked and damaged by rainwater due to water accumulation in the optical cable surplus cable box during heavy rain weather. At the same time, the nine-axis sensor 10 can detect the position and tilt angle of the floor-standing optical cable surplus cable box and transmit the information to the server through the wireless signal transmission device 9. The tilt of the inner box caused by the damage of the support column 4 or the tilt of the outer box caused by the foundation settlement can be transmitted to the server in time for the staff to check and repair in time. As an integrated sensor module, the nine-axis sensor 10 reduces the circuit board and the overall space, and occupies less space in the inner box 2. At the same time, the algorithm of the nine-axis sensor 10 can fuse data from multiple sensors, making up for the deficiency of a single sensor in calculating the accurate position and direction, thereby realizing high-precision motion detection.

[0024] In this embodiment, the buoyancy assembly 6 includes a buoyancy ball 61 and a plurality of limiting columns 62 arranged on the bottom wall of the outer box body 1 to prevent the buoyancy ball 61 from moving horizontally. Preferably, four limiting columns 62 are arranged to limit the buoyancy ball 61 from four directions to prevent the buoyancy ball 61 from moving horizontally in any direction under the push of water. A sealing member is arranged on the side of the drain plate 5 facing the drain hole, so that the drain plate 5 has a better sealing effect on the drain hole and prevents water from flowing back to the inner box body 2. A limiting groove 7 for limiting the drain plate 5 is arranged on the side of the bottom wall of the inner box body 2 facing the outer box body 1. The limiting groove 7 is connected with the inner drainage hole 21, and the cross-sectional area of ​​the limiting groove 7 gradually increases along the direction from the inner box body 2 to the outer box body 1, so as to facilitate the discharge of water in the inner box body 2. At the same time, the limiting groove 7 guides the drainage board 5 that enters the limiting groove 7 to close the inner drainage hole 21, so as to facilitate the drainage board 5 to accurately close the inner drainage hole 21. Preferably, the bottom wall of the outer box body 1 is provided with an outer drainage hole 11 for discharging the water in the drainage channel 3, so as to discharge the water in the drainage channel 3 in time and prevent the drainage board 5 from closing the inner drainage hole 21 due to excessive water in the drainage channel 3, so that the accumulated water in the inner box body 2 cannot be discharged.

[0025] When there is no water accumulation in the optical cable well, the buoyancy ball 61 is against the bottom wall of the outer box body 1 under the action of gravity. At the same time, the buoyancy ball 61 is located between the four limit columns 62, so that the buoyancy ball 61 can only move up and down to prevent the buoyancy ball 61 from rolling in the drainage channel 3. The drainage board 5 does not close the inner drainage hole 21. When water enters the inner box body 2, the water will flow into the drainage channel 3 along the inner drainage hole 21, and then be discharged from the outer box body 1 through the outer drainage hole 11; as the water level in the drainage channel 3 rises, the buoyancy ball 61 moves upward under the action of buoyancy, pushing the drainage board 5 upward until the drainage board 5 closes the inner drainage hole 21, preventing the water in the drainage channel 3 from flowing back into the inner box body 2, thereby keeping the inner box body 2 dry.

[0026] In this embodiment, a water level sensor 8 is provided in the drainage channel 3 between the side walls of the inner box body 2 and the outer box body 1. The water level sensor 8 is electrically connected to the wireless signal transmission device 9. The water level sensor 8 monitors the water level in the drainage channel 3 in real time, and transmits it to the server through the wireless signal transmission device 9 so that the staff can observe it in real time. When there is too much water in the drainage channel 3 and the external drainage hole 11 has no time to drain the water, the staff can open the outer box door of the outer box body 1 to manually drain the drainage channel 3, keep the inner box body 2 dry, and prevent water accumulation from damaging the remaining optical cable.

[0027] In this embodiment, the wireless signal transmission device 9 is a NB-IOT terminal. The sensor can transmit information to the server through the NB-IOT terminal. The NB-IOT terminal has the advantages of wide coverage and low power consumption. The signal coverage area of ​​the NB-IOT terminal is much larger than that of the traditional GSM. The NB-IOT technology introduces the eDRX power saving technology and the PSM power saving mode, that is, the NB-IOT terminal transmits a signal once in a period of time, and the NB-IOT terminal will enter a dormant state when it does not transmit a signal, which further reduces power consumption and prolongs the battery life. At the same time, the NB-IOT terminal has the advantage of low cost, good transmission effect and energy saving. Using the NB-IOT terminal as the wireless signal transmission device 9 allows the floor-standing optical cable surplus cable box to remain in working condition for a long time.

[0028] Embodiment 2:

[0029] The difference between this embodiment and the first embodiment is that the wireless signal transmission device 9 is a 4G / 5G wireless signal transmission device, which has a fast transmission speed, low latency and low energy consumption.

[0030] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
