Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a micro-vibration-based early warning device for water inrush on the foundation plate. Background Technology

[0002] The lower edge of the box girder section is called the base plate, which is the main working part that bears positive and negative bending moments. In reinforced concrete bridges, it must be sized sufficiently to accommodate the required tensile reinforcement. In prestressed reinforced concrete bridges, it needs a sufficiently large bearing area to meet the compression requirements during the operational phase.

[0003] A tunnel water inrush early warning and monitoring device, patent application number CN202420658897.6, relates to a tunnel water inrush early warning and monitoring device, which includes a tunnel water inrush early warning and monitoring device body. Placement components are fixedly connected to both sides of the tunnel water inrush early warning and monitoring device body. Each placement component includes a mounting plate. A first handle is fixedly connected to the center of the side wall of the mounting plate near the top. A mounting block is fixedly connected to the center of the side wall of the mounting plate. A first connecting rod is movably connected through the upper and lower ends of the mounting block. A first pressing block is fixedly connected to the bottom end of the first connecting rod. A first spring is sleeved on the outer side of the first connecting rod, located between the first pressing block and the mounting block. A second handle is fixedly connected to the top end of the first connecting rod. Sleeves are fixedly connected to the front and rear ends of the mounting plate. A support column is movably connected through the bottom end of the sleeves. This improves the placement stability of the tunnel water inrush early warning and monitoring device body, preventing the device body from tipping over and being damaged due to unstable placement.

[0004] In the disaster early warning process, the detection of sudden water in the foundation slab is difficult, which can easily lead to untimely detection of emergency situations in the foundation slab, poor detection efficiency in the event of sudden microseismic events, and the suppression of groundwater by sudden protective measures, resulting in low efficiency of emergency evacuation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution:

[0028] A micro-vibration-based early warning device for water inrush on the foundation includes a micro-vibration mechanism 1. The micro-vibration mechanism 1 includes a support frame 11 supported by the ground. A first outer frame bracket 12 is installed at each of the four corners of the top of the support frame 11. Rubber strips 13 are respectively provided on both sides of the top of the first outer frame bracket 12. A lifting frame 14 is provided at the end of the rubber strips 13. A fitting top plate 15 for support is provided at the middle of the top of the lifting frame 14. A hinged drive roller 16 is provided at the end of the fitting top plate 15. A sleeve base 17 is provided at the middle of the top of the fitting top plate 15.

[0029] In this embodiment: both ends of the top plate 15 are provided with hinged roller shafts 171, and both ends of the hinged roller shafts 171 are respectively sleeved with inclined connecting rods 18, and a buffer spring 19 is installed at the cross position in the middle of the inclined connecting rods 18.

[0030] The movement is achieved by using a rod structure consisting of a hinged roller shaft 171 and an inclined connecting rod 18.

[0031] In this embodiment: an upper frame 192 is installed at the top of the inclined connecting rod 18, a first sleeve is provided at the four corners of the upper frame 192, a connecting rod 191 is provided at the bottom of the first sleeve, and a trapezoidal bracket 193 is provided at the middle of the bottom end of the upper frame 192.

[0032] By using the ground frame 192 and the sleeve lifting component, the position of the top plate 15 can be changed gradually with the ground when the lifting frame 14 is moved up and down to achieve the purpose of lifting and supporting.

[0033] In this embodiment: a water-bursting airbag mechanism 2 is installed on the side wall of the sleeve base 17;

[0034] The water-burst airbag mechanism 2 includes a concave bracket 21 disposed on the side wall of the top plate 15. The end of the concave bracket 21 is provided with a second sleeve 22 for binding. The top center of the second sleeve 22 is provided with a cylinder bracket 23. The top center of the cylinder bracket 23 is equipped with a scheduling block 24.

[0035] The second sleeve 22 and the cylinder support 23 are used. The second sleeve 22 is adapted to install the groundwater monitoring component, and further the detection cylinder 25, which serves the purpose of detection, is installed so that subsequent water seepage can be detected in time by the detection cylinder 25.

[0036] In this embodiment: a detection cylinder 25 is installed in the middle of the second sleeve 22, a second outer frame bracket 26 is provided at the bottom of the detection cylinder 25, a sliding support rod 28 is installed at the top of the second outer frame bracket 26, a connecting block 29 is provided at the top of the sliding support rod 28, a sliding sleeve 291 is provided at the top of the connecting block 29, a threaded sleeve 292 is provided on the back of the sliding sleeve 291, and a fastening threaded sleeve 293 for sliding displacement is provided in the middle of the threaded sleeve 292.

[0037] The purpose of using threaded sleeve 292 and fastening threaded sleeve 293 is that when threaded sleeve 292 rotates, the surface of fastening threaded sleeve 293 rotates and moves back and forth along the surface of transmission screw 294.

[0038] In this embodiment: a transmission screw 294 is threadedly installed in the middle of the fastening threaded sleeve 293, a drive motor 295 is drivenly installed at the bottom of the transmission screw 294, the output end of the drive motor 295 is connected to the transmission screw 294, and a transverse lifting mechanism 3 is installed at the end of the connecting block 29.

[0039] The lateral lifting mechanism 3 includes a bearing block 31 installed at the end of the connecting block 29, a connecting crossbar 32 installed on the side wall of the bearing block 31, and a hinge 33 installed at the end of the side wall of the connecting crossbar 32.

[0040] The use of the bearing block 31 and connecting crossbar 32 further enables the transfer, and the use of the hinge 33 and connecting crossbar 32 completes the hinge connection.

[0041] In this embodiment: the bottom end of the hinge 33 is provided with a sliding rail 34, and the side wall of the sliding rail 34 is equipped with an access base 35 for guidance. The middle part of the access base 35 is traction-equipped with the upper frame 192.

[0042] The upper frame 192 is supported by a sliding track 34, and the upper frame 192 and the sliding track 34 work together to achieve linkage.

[0043] In practical use, the first step is to first and foremost connect the water-bearing plate structure to the location in the mine shaft where underground cracks are likely to occur.

[0044] Step 1 utilizes the support frame 11 and one end of the first outer frame bracket 12 to achieve contact. After clamping with the rubber strip 13, it connects to the side wall of the lifting frame 14. The axial deflection of the drive roller 16 drives the position of the sleeve base 17 to change angle. When the bonding top plate 15 needs to be directly pressed into the area prone to water leakage, personnel need to use the specific upper frame 192 and specific connecting rod 191 for assembly. The main purpose is to ensure that the bonding top plate 15 is assembled together with sufficient pressure to improve the vibration intensity of the water leakage position below. Through the elastic state of the specific buffer spring 19, quick and convenient assembly with the bonding top plate 15 is achieved.

[0045] Step 2: Compaction and ground water inrush early warning monitoring;

[0046] At this time, according to the supporting role of the second outer frame bracket 26, for the installation of the top sliding support rod 28, the drive motor 295 is turned on, and then the motor drives the transmission screw 294 to rotate, thereby controlling the threaded sleeve 292 to move linearly along the transmission screw 294. When moving, it controls the connecting block 29 to slide up and down. When sliding, it coordinates the up and down movement of the upper frame 192 until the guide rod 191 and the upper frame 192 are lowered to reduce pressure. The buffer spring 19 ensures that the weight can be changed by the position of the support frame 11 below. Moreover, the tilting rod 18 changes the direction of the support of the two sides of the top plate 15 and the unfolded weight. Finally, the detection process is that when there is a sudden underground vibration, the second sleeve 22 held by the concave bracket 21 reaches the water level pressure. The vibration level is detected by the detection cylinder 25 and its precision instruments. When a sudden situation occurs, an alarm can be set in time.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
