[0001] The invention relates to the technical field of vibration monitoring devices, in particular to a blasting vibration monitoring device for collecting data at any depth in a soil body. Background Art

[0002] Blasting engineering is a common construction method in construction, mining, tunneling and other projects. It can achieve a large amount of rock and soil crushing and mining in a short time, improving project efficiency. However, due to the particularity of blasting engineering, a large amount of vibration and shock waves will be generated during construction, affecting the surrounding environment and building structures. Therefore, blasting vibration monitoring is required to ensure construction safety.

[0003] The existing blasting vibration monitoring methods are mostly to place monitoring equipment at preset monitoring points and complete vibration monitoring through the monitoring equipment. However, when the blasting point is located deep in the soil, there is a certain error in vibration monitoring by relying on vibration transmission to the ground. Therefore, when facing blasting vibration monitoring deep in the soil, it is usually necessary to dig a foundation pit and place monitoring equipment for vibration monitoring. It is labor-intensive and inconvenient to operate. In order to ensure the comprehensiveness of monitoring, multiple sets of monitoring devices need to be set up, and the monitoring personnel obtain the monitoring results in sequence at the monitoring site. It is not conducive to obtaining the abnormal state of vibration monitoring in the first time. To this end, we propose a blasting vibration monitoring device that collects data at any depth in the soil. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 As shown, a blasting vibration monitoring device for collecting vibrations at any depth in a soil body comprises a fixed plate 1, a limiting groove 2 is provided in the middle of the upper surface of the fixed plate 1, an assembly opening 3 is provided in the middle of the ground in the limiting groove 2, a vibration monitor 7 is installed on the fixed plate 1 through the inner surface clamping of the limiting groove 2, the inner surface size of the limiting groove 2 matches the outer surface size of the vibration monitor 7, positioning grooves are provided on the four sides of the upper part of the inner surface of the limiting groove 2, a protective cover 5 is provided on the upper surface of the fixed plate 1, a warning light 18 is fixedly installed in the middle of the upper surface of the protective cover 5, an annular mounting screw groove 4 is provided on the upper surface of the fixed plate 1, and the fixed plate 1 is provided with a mounting screw groove 4 through the mounting screw groove 4. The inner surface is spirally inserted with a mounting screw ring 6, which is integrally connected to the lower surface of the protective cover 5. Block assemblies 17 are fixedly installed on the four sides of the middle part of the upper surface of the fixed disk 1. The block assembly 17 consists of a fixed block, a compression spring, a clamping block and a limit block. Compression springs are welded and fixedly installed on both ends of the middle part of the fixed block close to the outer surface of the limit groove 2. The other end of the compression spring is jointly welded and fixedly installed with a clamping block. The upper part of the outer surface of the clamping block close to the limit groove 2 is arranged in an inclined shape. Limiting blocks in the shape of an inverted "T" protrusion are integrally provided on both sides of the middle part of the lower surface of the clamping block. The limit blocks are embedded and slidably installed in the positioning groove;

[0030] The vibration monitor 7 can be installed and fixed by cooperating with the fixing plate 1 and the limiting groove 2. When the vibration monitor 7 is inserted into the limiting groove 2, it will contact with the block assembly 17. Since the clamping block of the block assembly 17 is inclined on the upper part of the outer surface of the limiting groove 2, it is convenient for the vibration monitor 7 to open the block assembly 17 and insert it into the limiting groove 2 for installation. When the block assembly 17 is opened, the compression spring will shrink to drive the clamping block to move toward the fixed block until it contacts the outer surface of the vibration monitor 7. At this time, the clamping block can clamp the vibration monitor 7 under the elastic action of the compression spring. The assembly port 3 is used to facilitate the installation and connection of the fixing plate 1 and the drill rod 9. The protective cover 5 is made of transparent acrylic material. The protective cover 5 can be installed and connected with the fixing plate 1 by installing the screw ring 6 and the installing screw groove 4. While protecting the vibration monitor 7, it is convenient to view the vibration monitoring data of the vibration monitor 7.

[0031] A hollow drill rod 9 is installed below the fixed disk 1, and a protruding docking joint 11 is provided at one end of the drill rod 9. The drill rod 9 is installed in the assembly port 3 and connected to the fixed disk 1 through the screw plug 11. The inner surface of the other end of the drill rod 9 is provided with a docking port matching the docking joint 11. A separation screw blade 10 is fixedly installed on the outer surface of the drill rod 9. A drill bit 12 is installed below the drill rod 9. A protruding adapter 13 is provided on the upper surface of the drill bit 12. The drill bit 12 is installed in the docking port through the adapter 13. The outer surfaces of the docking joint 11 and the adapter 13 are both provided with external threads, and the inner surfaces of the assembly port 3 and the docking port are both provided with internal threads matching the docking joint 11.

[0032] The docking joint 11 and the docking port provided on the drill rod 9 can facilitate the assembly and connection of each section of the drill rod 9, and then the length of the drill rod 9 can be adjusted according to the soil depth of the required monitoring position. The drill bit 12 can be installed and connected to the drill rod 9 through the adapter 13. At this time, a motor or other driving device is used to connect the drill rod 9. The drill bit 12 can be used to drill into the soil for vibration monitoring. The soil around the drill rod 9 can be loosened by separating the screw blades 10 to facilitate the entry and exit of the drill rod 9 in the soil.

[0033] A fixed sleeve 14 is installed in the middle of the upper surface of the drill bit 12, and a vibration sensor 8 is inserted and installed on the inner surface of the fixed sleeve 14. The vibration sensor 8 and the vibration monitor 7 are connected through a wire passing through the drill rod 9. The outer surface of the connecting wire between the vibration monitor 7 and the vibration sensor 8 is wrapped with a winding coil 16, and a plurality of conductive connecting rods 15 are provided on the outer surface of the fixed sleeve 14. The other end of the conductive connecting rod 15 is connected to the inner surface of the adapter 13.

[0034] The vibration sensor 8 can be installed and fixed in the drill bit 12 through the fixing sleeve 14 to prevent the vibration sensor 8 from loosening during use and affecting monitoring. When the drill bit 12 reaches the specified position in the soil, it can cooperate with the conductive connecting rod 15 arranged inside to transmit the vibration to the vibration sensor 8 when in contact with the blasting vibration, and transmit the vibration to the vibration monitor 7 through the vibration sensor 8 through the wire to complete the vibration monitoring. The winding wire 16 is wound around the surface of the wire to protect the wire while keeping the wire in a vertical and stable state, so as to avoid the problem of the wire winding when the vibration sensor 8 rotates into the soil as the drill bit 12, and the specific length of the wire can be selected according to the required depth into the soil.

[0035] The vibration monitor 7 has a built-in vibration monitoring system, which includes a value acquisition module, a value preset module and an analysis module;

[0036] The value acquisition module is used to acquire the vibration value monitored by the vibration monitor 7 in real time and transmit the acquired value to the analysis module;

[0037] The numerical value preset module is used to preset the vibration monitoring value, and set the maximum value to the minimum value of the preset vibration value as the normal reference range of vibration;

[0038] The analysis module is used to analyze the received vibration value and match the monitored value with the preset value. If the match is successful, it indicates that the monitored value is within the normal reference range of vibration. If the match fails, it indicates that the monitored value is outside the normal reference range of vibration. A vibration abnormality signal is generated and transmitted to the execution terminal. The execution terminal is connected to the warning light 18 via a wireless signal. The execution terminal controls the warning light 18 to start execution according to the received vibration abnormality signal.

[0039] When the present invention is in use, the vibration sensor 8 can first be inserted and installed in the fixing sleeve 14 provided in the drill bit 12 for fixing. At this time, the other end wire of the vibration sensor 8 can be passed through the drill rod 9 and the drill bit 12 can be installed and connected with a section of the drill rod 9. At this time, the driving device such as the motor can be connected to the other end of the drill rod 9, and the drill rod 9 can be controlled to rotate to cooperate with the drill bit 12 to drill into the soil. When the end of the drill rod 9 connected to the driving device is close to the soil and the drill bit 12 fails to reach the designated monitoring position, the driving device can be separated from the drill rod 9 and another section of the drill rod 9 can be connected to it. At this time, the driving device can be used to continue to control the drill rod 9 to penetrate into the soil until the drill bit 12 reaches the designated monitoring position in the soil. The length of the drill rod 9 can be compared with the depth of the designated position to determine whether it has been reached;

[0040] Secondly, when the drill bit 12 reaches the designated monitoring position in the soil, the fixed plate 1 and the drill rod 9 exposed to the outside can be installed and connected to each other, and the other end of the wire can be connected to the vibration monitor 7. The connected vibration monitor 7 can be installed on the fixed plate 1 to perform vibration monitoring. When the vibration generated by the blasting propagates in the soil and contacts the drill bit 12, the vibration sensor 8 can receive the vibration intensity and transmit it to the vibration monitor 7 to obtain vibration data, thereby completing the blasting vibration monitoring in the soil. At the same time, the protective cover 5 can be installed on the fixed plate 1 and cover the vibration monitor 7 to prevent the vibration monitor 7 from being damaged during exposure to the ground.

[0041] When the vibration monitor 7 obtains the vibration data, the value acquisition module can acquire the vibration value in real time and transmit the acquired value to the analysis module. The analysis module simultaneously reads the normal reference interval data of the vibration monitoring value preset in the value prediction module, and matches the acquired real-time vibration monitoring value with the preset normal reference interval. If the match is successful, it indicates that the monitoring value is within the normal reference interval of vibration. If the match fails, it indicates that the monitoring value is outside the normal reference interval of vibration. Based on the state of matching failure, the analysis module will synchronously generate a vibration abnormality signal and transmit the vibration abnormality signal to the execution terminal. When the execution terminal receives the vibration abnormality signal, it controls the warning light 18 to issue a warning through the wireless signal connection between it and the warning light 18, so as to quickly prompt the monitoring personnel that the vibration monitoring is abnormal.
