Description

Technical Field

[0001] This utility model belongs to the field of underground engineering technology, specifically relating to a protective box suitable for a full fiber optic microseismic monitoring system in tunnels. Background Technology

[0002] In existing tunnel microseismic monitoring systems, piezoelectric sensors are mostly used to receive micro-fracture signals and convert them into electrical signals for transmission. However, this type of microseismic system experiences significant signal attenuation during long-distance transmission, making it unsuitable for long-distance monitoring. Therefore, all-fiber optic microseismic monitoring systems have emerged.

[0003] However, as a new generation of microseismic monitoring systems, all-fiber optic microseismic monitoring systems currently lack dedicated safety enclosures. Furthermore, existing protective enclosures for microseismic monitoring systems primarily protect the acquisition system itself, failing to provide real-time display of microseismic event changes. However, with algorithm improvements, real-time early warning for microseismic monitoring has become possible, allowing waveform signals acquired on-site to be converted into microseismic events in real time. Therefore, adding real-time displays of microseismic event changes at construction sites can reduce the time required for rockburst warnings and enhance on-site safety during construction.

Detailed Implementation

[0031] The present invention will now be described in detail with reference to specific embodiments.

[0032] This invention provides a protective box for a full fiber optic microseismic monitoring system in tunnels, which can provide all-round protection for the full fiber optic microseismic monitoring system and allow for a direct view of the system's operating status.

[0033] like Figure 1 As shown, the protective box of the all-fiber microseismic monitoring system in the tunnel of this utility model includes an outer protective box 13-1, and an inner placement box 13-2 is set inside the outer protective box 13-1.

[0034] The outer protective box 13-1 includes vertically arranged main columns 1-1, 1-2, 1-3, and 1-4. These columns are positioned at the four corners of a rectangle. Two main columns on the same side are connected by a support platform 9. The support platform 9 has two layers, totaling eight platforms, forming a cuboid frame. Figure 3 As shown, the width of the left, right, and back support platforms 9 is the same as the main column, while the width of the front support platform 9 is smaller than the main column to allow space for the installation of the box door; the four-sided cuboid frame is equipped with a left side protective layer, a right side protective layer, a back side protective layer, a top protective layer, and a bottom protective layer; after the production is completed, it is necessary to ensure that the outer protective box is well sealed to achieve functions such as noise reduction, dust reduction, and waterproofing.

[0035] The inner placement box 13-2 is divided into a first placement space 4-1, a second placement space 4-2, and a third placement space 4-3 from top to bottom. The first placement space 4-1 includes four vertically arranged upper transparent protective panels 14-1, which are respectively located on the front, rear, left, and right sides. A tray 12-1 is horizontally arranged below the upper transparent protective panels 14-1. The top surfaces of the upper transparent protective panels 14-1, the tray 12-1, and the outer protective box 13-1 form the first placement space 4-1. The second placement space 4-2 includes four vertically arranged lower transparent protective panels 14-2. Four lower transparent protective panels 14-2 are respectively installed on the front, rear, left, and right sides; a second tray 12-2 is horizontally installed below the lower transparent protective panels 14-2; the lower transparent protective panels 14-2, the second tray 12-2, and the first tray 12-1 form a second installation space 4-2; four upper transparent protective panels 14-1 are installed above the upper platform 9, and each of the four upper transparent protective panels 14-1 is connected to two main columns on the corresponding side; four lower transparent protective panels 14-2 are installed between the upper platform 9 and the lower platform 9, and each of the four lower transparent protective panels 14-2 is connected to two main columns on the corresponding side. The protective panel on the front side is connected to the main column by screws, and the main column is provided with screw holes 11. The protective panels on the other three sides are connected to the main columns by adhesive bonding, which facilitates later inspection and maintenance, and adhesive bonding can reduce noise caused by vibration.

[0036] like Figure 2 As shown, pallet 12-1 is placed on the upper platform 9, and pallet 2 12-2 is placed on the lower platform 9. The front and rear ends of pallet 12-1 and pallet 2 12-2 overlap on the platform 9. Space should be reserved between the protective panels on the front and rear sides and the platform 9 for placing the pallets. The dimensions of the transparent protective panels, platforms, and pallets are set according to actual needs to ensure that the pallets can be easily picked up and placed and are placed stably.

[0037] like Figure 3 As shown, the outer protective box 13-1 has a first door 3-1 and a second door 3-2 on its front side. The first door 3-1 is located in front of the first placement space 4-1, and the second door 3-2 is located in front of the second placement space 4-2 and the third placement space 4-3. Symmetrical square notches are provided on the main columns 1-1 and 2-2 for installing the first door 3-1 and the second door 3-2, which are embedded inside the main columns. The first door 3-1 and the second door 3-2 are connected to the main column 1-1 on one side by a hinge 5, and to the main column 2-2 on the other side by a safety lock 6. The first placement space is where the monitor is placed and is frequently opened to observe micro-vibration changes; it is protected by the first door. The second and third spaces are where the acquisition system is placed and are opened less frequently; they are protected by the second door. Distinguishing between the doors helps ensure equipment safety.

[0038] The outer protective box 13-1 has a protective layer wire passage hole 7-1 on its side, and the inner placement box 13-2 has a protective plate wire passage hole 7-4 on its side. The protective layer wire passage hole 7-1 and the protective plate wire passage hole 7-4 are coaxially arranged. Both tray one 12-1 and tray two 12-2 have tray wire passage holes 7-3.

[0039] The inner layer housing 13-2 is equipped with a heat dissipation fan 8, which is fixed to the inner wall of the inner layer housing 13-2. In this embodiment, the heat dissipation fan is installed on the protective plates on the left and right sides of the second housing space. The outer layer protective box 13-1 is provided with side protective layer heat dissipation holes 7-2 on the side protective layer.

[0040] The third installation space 4-3 is equipped with an optical cable winch 10, which is connected to the bottom protective layer via a bayonet. The main optical fiber cable of the all-fiber microseismic monitoring system is installed on the optical cable winch 10. The hardware of the all-fiber microseismic monitoring system is placed on tray 2 12-2. The display of the all-fiber microseismic monitoring system is placed on tray 1 12-1. Brakeable casters 2 are installed under the main columns 1-1, 2-2, 3-3 and 4-4.

[0041] In this example, the four main columns, five protective layers, two single-sided doors, bottom tray of the inner placement box, and the support platform between the main columns are all made of the same material: stainless steel. The interior of the main columns is made of solid cubic material. The side protective panels of the inner placement box are all made of the same material: transparent high-strength plastic. The four brakeable casters are all made of the same material: rubber. The use of stainless steel is simple to process and inexpensive to manufacture, lightweight yet strong, and can operate continuously in high-temperature and high-humidity environments. The transparent high-strength plastic material allows for a direct view of the micro-seismic monitoring system's operating status and the micro-seismic changes displayed on the monitor. The rubber material reduces vibrations caused by construction disturbances, thereby reducing vibrations in the all-fiber optic micro-seismic system.

[0042] This utility model relates to the installation method of the protective box for a full fiber optic microseismic monitoring system in tunnels, specifically including the following steps:

[0043] Step 1: Place the protective box in a suitable position inside the tunnel and put the casters in the brake position;

[0044] Step 2: Place the main fiber cable on the optical cable winch 10 in the third placement space 4-3, and pass one end of the main cable through the protective layer cable hole 7-1 and the other end through the cable hole of tray 2 12-2, and place tray 2 12-2 on the support platform 9 in sequence.

[0045] Step 3: Place the all-fiber microseismic monitoring system hardware on tray 2 12-2 and connect the lines between them. Finally, pass the required power and data cables through the cable hole 7-3 of tray 1 12-1 and place tray 1 12-1 on the support 9 in sequence.

[0046] Step 4: Place the micro-vibration system display on tray 12-1 and connect all the lines. At the same time, connect all the lines to the power supply that enters the protective box through the protective layer wire hole 7-1 and the protective plate wire hole 7-4. This completes the connection of the all-fiber micro-vibration system.

[0047] Step 5: Protect and secure all wiring at the cable routing holes, then close and lock the cabinet door. Use is now complete.
