Description

Technical Field

[0001] The utility model relates to the technical field of blasting vibration measuring instruments, in particular to a wireless charging blasting vibration measuring instrument with a fixed sensor structure. Background Art

[0002] The blasting vibration meter is a special device for long-term collection and recording of blasting vibration and impact signal data on site. Before data collection, the sensor is placed on the lining, and the sensor is connected to the lining through the solidification of gypsum. After the sensor is connected to the vibration meter through a transmission wire, the blasting vibration and impact signal data can be collected.

[0003] However, the existing blasting vibration meter still has room for improvement in actual use. On the one hand, the sensor is fixed by lime solidification. When the blasting vibration is too large or the lining is too large, the lime block will break, thus affecting the tightness of the sensor and the lining, and further affecting the accuracy of the sensor data collection. On the other hand, the existing blasting vibration meter needs to collect and record data for a long time during work, which often leads to insufficient power. The existing charging method requires the vibration meter to be taken back to the charging station for charging, and it can be used again after the power is fully charged.

[0004] Therefore, those skilled in the art provide a wireless charging blasting vibrometer with a fixed sensor structure to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to at least overcome the above-mentioned deficiencies, the purpose of the present application is to provide a wireless charging blasting vibrometer with a fixed sensor structure.

[0006] The purpose of the utility model is mainly achieved through the following technical solutions:

[0007] This application example provides a wireless charging blasting vibration meter with a fixed sensor structure. Its components include:

[0008] Vibrometer body, power supply, fixture and sensor;

[0009] The power supply device is provided with a charging base for charging the vibration meter body;

[0010] The fixture is a frame structure with connecting parts;

[0011] The fixture is provided with a fastener connected and fixed to the sensor;

[0012] Below the fastener, the fixture is provided with an accommodation space for accommodating the sensor;

[0013] Outside the accommodation space, the fixture is provided with a connecting piece which is connected and fixed to the lining;

[0014] On the outside of the accommodation space, the fixture is also provided with a slot for the sliding plug-in to connect and reciprocate;

[0015] The sliding insert is fixed to the lining.

[0016] When this embodiment is implemented, the fixture is composed of a transverse steel bar and two longitudinal steel bars. The central bottom of the transverse steel bar has a bolt head for connecting the sensor. The two ends of the transverse steel bar and the longitudinal steel bar are bent inward by 90° to form a storage space for accommodating the sensor. The two ends of the transverse steel bar and the longitudinal steel bar are bent outward by 90° to achieve the end of the fixture and the lining. The two ends of the transverse steel bar are provided with bolt holes for bolting to the lining, and the two ends of the longitudinal steel bar are provided with slots for the plug-in to slide back and forth. The sensor is placed in the storage space of the fixture, and the bolt head of the fixture is inserted into the bolt hole of the sensor for connection. The sliding plug-in is inserted into the slot of the fixture, and the fixture and the lining are connected by bolts; since the sliding plug-in can slide along the slot and the sliding direction is perpendicular to the extension direction of the lining crack, as the lining crack extends, the sliding plug-in can slide along the slot to a certain extent, thereby reducing the disturbance caused by the development of the lining crack to the sensor and improving the measurement accuracy.

[0017] As a further solution of the utility model: the clamp is a frame structure composed of transverse steel bars, longitudinal steel bars and sliding plug-ins.

[0018] The advantage of this solution is that the transverse steel bars and longitudinal steel bars in the frame structure have strong rigidity when combined together, which can provide good support and stability for the sensor.

[0019] As a further solution of the utility model: the fastener is located at the center bottom of the transverse steel bar.

[0020] The advantage of this solution is that the sensor can be firmly connected to the fixture by fastening the sensor with a bolt head, and there is no risk of loosening and falling off between the fixture and the sensor due to explosion or development of lining cracks.

[0021] As a further solution of the utility model: the transverse steel bars are orthogonal to the longitudinal steel bars;

[0022] Both ends of the transverse steel bar are provided with bolt holes for bolting with the lining;

[0023] Both ends of the longitudinal steel bar are provided with slots for the plug-in to slide back and forth.

[0024] The advantage of this solution is that the two ends of the transverse steel bar and the longitudinal steel bar are bent inwards 90° once to form a storage space for accommodating the sensor, and the two ends of the transverse steel bar and the longitudinal steel bar are bent outwards 90° twice to achieve the end of the clamp fitting with the lining. The two ends of the transverse steel bar are provided with bolt holes for bolting to the lining, and the two ends of the longitudinal steel bar are provided with slots for the reciprocating sliding of the plug-in. By forming a storage space for accommodating the sensor by bending once, the support points of the sensor can be increased, the stability and anti-swing ability of the sensor can be improved, and the sensor can be prevented from loosening or tilting; by bending twice, the two ends of the transverse steel bar and the longitudinal steel bar can fit with the lining, which improves the clamping force, can better fix the clamp and the lining, and can ensure the sensor

[0025] The stability of the sensor in the fixture.

[0026] As a further solution of the utility model: the sliding plug-in is a rectangular structure, the connecting piece is a rectangular structure, and the central axis of the sliding plug-in and the central axis of the connecting piece are perpendicular to each other.

[0027] The advantage of this solution is that the mutually perpendicular sliding plug-in and connector are stable during installation, which can reduce shaking and looseness caused by installation. In addition, since the sliding plug-in and connector are mutually perpendicular and independent of each other, it can be ensured that as the lining cracks develop, the sliding plug-in is not disturbed by the connector during the sliding process.

[0028] As a further solution of the utility model: the sliding plug-in is a rectangular structure, and the central axes between the sliding plug-ins are parallel or overlapped.

[0029] The advantage of this solution is that as the lining cracks develop, the sliding of the sliding plug-ins will not interfere with each other, which reduces the friction resistance during the sliding process and can extend the service life of the sliding plug-ins.

[0030] As a further solution of the utility model: the power supply device is provided with a protective shell, a battery is provided in the shell of the protective shell, and a wireless base for magnetically charging the vibration meter body is provided above the battery.

[0031] When this embodiment is implemented, the vibrometer body is placed on the wireless charging base in the protective shell of the power supply device. The protective shell can protect the vibrometer body during the blasting process to reduce the impact of the blasting. At the same time, the wireless charging uses the principle of electromagnetic induction for charging. The closed electromagnetic coil of the vibrometer body is magnetically fixed to the power supply device, and the AC power is released through the discharge battery of the power supply device. The first control circuit of the power supply device converts the AC power into a high-frequency AC current. The reverse closed electromagnetic induction coil of the power supply device converts the high-frequency AC current into an alternating magnetic field to emit magnetic energy to the outside. The closed electromagnetic coil of the vibrometer body receives the magnetic energy emitted to the outside and generates an alternating current in the receiving coil. The semiconductor element of the control circuit of the vibrometer body converts the alternating current into a direct current, and the direct current is stored in the charging battery of the vibrometer body through the energy storage circuit.

[0032] As a further solution of the utility model, a screen for displaying the battery power and a charging switch are arranged outside the protective shell.

[0033] When this embodiment is implemented, the vibration meter body can be charged by opening and closing the switch, and at the same time, it can be observed through the screen whether the vibration meter is fully charged.

[0034] As a further solution of the utility model: a window for debugging the vibration meter body and a transparent sealing plate for closing the window are arranged outside the protective shell.

[0035] When this embodiment is implemented, the vibration meter body is placed on the wireless charging base in the protective shell of the power supply device. During debugging, the cover plate is opened to debug the vibration meter body. After debugging, the window is closed by the cover plate to protect the vibration meter body and reduce the impact during the blasting process.

[0036] In addition, the transparent cover plate allows test personnel to observe, collect and record data at any time, and also allows them to observe whether the vibration meter is working properly.

[0037] As a further solution of the utility model, its components also include:

[0038] Transmission conductors;

[0039] The vibration meter body and the sensor are connected via a transmission wire.

[0040] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The sensor is fixed to the lining by bolts and clamps. This fixing method is more stable than the traditional method of fixing with lime only. Compared with the traditional method of fixing with lime only, this fixing method can reduce the disturbance of the vibration meter body caused by the impact of blasting and the development of lining cracks, making the data collected by the sensor more accurate.

[0042] (2) The fixing direction of the fixture and the sliding direction of the plug-in are perpendicular to each other, which ensures that the working modes of each other are independent of each other and ensures that the plug-in is not disturbed by the fixed part during the sliding process.

[0043] (3) The wireless charging device and the magnetic charging of the vibration meter can extend the use time of the vibration meter and alleviate the power consumption anxiety caused by long-term on-site surveys.

[0044] (4) The protective shell of the power supply device can protect the vibration meter body and prevent the vibration meter body from being damaged by explosion impact.

[0045] (5) The window outside the protective shell allows operators to easily debug the vibration meter.

[0046] (6) The transparent cover plate allows operators to observe and record the data collected by the vibration meter while it is working, and also allows operators to observe whether the vibration meter is working properly. BRIEF DESCRIPTION OF THE DRAWINGS
