Description

Technical Field

[0001] This utility model relates to the field of tilt direction measurement technology, specifically a device for measuring the tilt direction of a dangerous rock mass. Background Technology

[0002] A dangerous rock mass refers to a rock mass that, although not yet collapsed, possesses the main geological conditions for collapse. Some rock masses have already shown signs of impending collapse, indicating that they may collapse soon. During the development and destructive process of a dangerous rock mass, changes in the interaction forces between different rock fragments can alter its tilt direction. Therefore, the tilt direction of a dangerous rock mass is not constant. Real-time measurement of the tilt direction of a dangerous rock mass can provide reference data on its development process and trend, and can also accurately determine the possible collapse direction in real time. This is of significant practical importance for the timely development of disaster prevention and evacuation plans and for ensuring the safety of people's lives and property.

[0003] Chinese patent provides an automated measuring device for the tilt direction of a rock mass, publication number CN215810822U. It includes a device housing fixed to the rock mass by an external support rod. Inside the housing are an internal module and a mounting shaft, which is fixedly connected to a mounting tray. An annular mounting groove is formed on the outer edge of the mounting tray, containing a resistor with an opening. A rotating shaft is fixedly connected to the mounting shaft and rotatably connected to a support rod. A rolling ring for reducing friction is provided between the support rod and the mounting tray. A mounting groove is formed on the support rod, containing a connecting wire. One end of the connecting wire is connected to a conductive connector. The conductive connector is slidably connected to the resistor. The power supply is electrically connected to an ammeter and one end of the resistor's opening sequentially via a wire.

[0004] However, devices used in the field for a long time are prone to accumulating dust and debris. The top of the device shell is the key area where the conductive connector and the ring resistor slide in contact. When the rock mass tilts, the support rod drives the conductive connector to slide on the resistor surface. If dust or debris accumulates in this area, it will lead to poor contact, measurement error of resistance value, or even short circuit, thereby affecting the measurement accuracy and greatly reducing the long-term stability and reliability of the device. Therefore, it is necessary to provide a measuring device for the tilt direction of the rock mass. Utility Model Content

[0005] The purpose of this invention is to provide a measuring device for the tilt direction of a dangerous rock mass, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for the tilt direction of a dangerous rock mass, comprising a measuring device body, wherein a self-cleaning mechanism is provided on the measuring device body; the self-cleaning mechanism includes a fixed frame mounted on the measuring device body, wherein a cleaning component and an air jet component are provided on the fixed frame; the cleaning component includes a micro motor mounted on the fixed frame, wherein the output shaft of the micro motor rotatably passes through the fixed frame and is fixedly connected to a fixed plate, wherein a brush plate is provided below the fixed plate, wherein a brush is provided at the bottom of the brush plate, wherein a sliding rod is fixedly mounted on the brush plate, wherein the top of the sliding rod slides through the fixed plate and is fixedly connected to a limit block, wherein a spring is sleeved on the sliding rod and disposed between the fixed plate and the brush plate; the air jet component includes a fixed block fixedly mounted on the fixed frame, wherein an air pipe is fixedly mounted on the fixed block, wherein multiple air jet nozzles are connected to the bottom of the air pipe, wherein a support frame is fixedly mounted on the fixed frame, wherein an air pump is mounted on the support frame, wherein a multi-port pipe connected to the air outlet of the air pump is fixedly mounted on the support frame, and a connecting pipe is connected between the multi-port pipe and the air pipe.

[0007] Preferably, both the fixing frame and the measuring device body are provided with screw holes, and bolts for fixing the fixing frame are threaded into the screw holes.

[0008] Preferably, a timer and a microcontroller are mounted on the mounting bracket, the timer is electrically connected to the microcontroller, and the micro motor and the air pump are both electrically connected to the microcontroller.

[0009] Preferably, the brush is made of an antistatic material, such as carbon fiber bristles, to avoid generating static electricity.

[0011] Preferably, a support column is fixedly provided at the bottom of the measuring device body, and a base is fixedly provided at the bottom of the support column, and a fixing hole for fixing the measuring device body is provided on the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1) The measuring device for the tilt direction of the unstable rock mass uses a micro motor to drive the fixed plate to rotate, which in turn causes the brush plate to rotate. When the brush plate rotates, the brush at the bottom can clean the top of the measuring device body, thereby removing dust and particles from the surface of the resistor and the sliding track of the conductive connector, ensuring stable contact between the conductive connector and the resistor. At the same time, through the setting of the slide rod, spring and limit block, the brush plate can always keep the brush in contact with the top of the measuring device body under the elastic action of the spring, thereby ensuring the cleaning effect.

[0013] 2) When the measuring device for the tilt direction of the unstable rock mass is cleaned by rotating the brush, the air pump is activated, which delivers air through the multi-port pipe and connecting pipe to multiple air pipes. The air is then sprayed downwards through multiple nozzles on the air pipes. The high-pressure airflow can blow away stubborn stains or fine particles on the top of the measuring device body. It is especially suitable for dry cleaning in humid environments. Through the combined action of the rotating brush and the high-pressure nozzles, dust and debris on the top of the measuring device body shell can be removed quickly and effectively, thereby effectively maintaining good contact of the conductive joints and improving measurement accuracy.

A cleaning component 54 and an air jet component 55 are provided on the fixing frame 51.

[0019] Specifically, the timer 56 allows for the preset of appropriate time intervals to trigger the self-cleaning mechanism 5 to work. The microcontroller 57 is used to receive signals from the timer, thereby controlling the start and stop of the micro motor 541 and the air pump 555. By removing the bolts 53 on the mounting bracket 51, the self-cleaning mechanism 5 can be quickly disassembled, which is beneficial for the maintenance and repair of the self-cleaning mechanism 5.

[0020] See Figure 2 and Figure 3 Furthermore, the cleaning assembly 54 includes a micro motor 541 mounted on a fixed frame 51. The output shaft of the micro motor 541 rotatably passes through the fixed frame 51 and is fixedly connected to a fixed plate 542. A brush plate 543 is provided below the fixed plate 542, and a brush 544 is provided at the bottom of the brush plate 543. The brush 544 is made of antistatic material, such as carbon fiber bristles, to avoid generating static electricity. A slide rod 545 is fixedly provided on the brush plate 543. The top of the slide rod 545 slides through the fixed plate 542 and is fixedly connected to a limit block 547. A spring 546 is sleeved on the slide rod 545 and is provided between the fixed plate 542 and the brush plate 543.

[0021] Specifically, by starting the micro motor 541 to drive the fixed plate 542 to rotate, the brush plate 543 can rotate accordingly. When the brush plate 543 rotates, the brush 544 at the bottom can clean the top of the measuring device body 1, thereby removing dust and particles from the surface of the resistor and the sliding track of the conductive connector, ensuring stable contact between the conductive connector and the resistor. At the same time, through the setting of the slide rod 545, spring 546 and limit block 547, the brush plate 543 can always keep the brush 544 in contact with the top of the measuring device body 1 under the elastic action of the spring 546, thereby ensuring the cleaning effect.

[0022] See Figure 4Furthermore, the jet assembly 55 includes a fixing block 551 fixedly mounted on a fixing frame 51, an air pipe 552 fixedly mounted on the fixing block 551, and a plurality of jet nozzles 553 connected to the bottom of the air pipe 552.

[0023] Specifically, when the brush 544 is used for rotary cleaning, the air pump 555 is activated, which delivers air through the multi-port pipe 556 and the connecting pipe 557 to multiple air pipes 552. The air is then sprayed downwards through multiple nozzles 553 on the air pipes 552. The high-pressure airflow can blow away stubborn stains or fine particles on the top of the measuring device body 1, which is especially suitable for dry cleaning in humid environments. Through the combined action of the rotating brush 544 and the high-pressure nozzles 553, dust and debris on the top of the measuring device body 1 can be removed quickly and effectively, thereby effectively maintaining good contact of the conductive connector and improving measurement accuracy.

[0024] In actual operation, the measuring device body 1 is fixedly installed in the designated position using the fixing hole 4, the base 3 and the support column 2. By starting the micro motor 541, the fixing plate 542 is rotated, which causes the brush plate 543 to rotate accordingly. When the brush plate 543 rotates, the brush 544 at the bottom can clean the top of the measuring device body 1, thereby removing dust and particles from the surface of the resistor and the sliding track of the conductive connector, ensuring stable contact between the conductive connector and the resistor. At the same time, through the setting of the slide rod 545, the spring 546 and the limit block 547, the brush plate 543 can always keep the brush 544 in contact with the top of the measuring device body 1 under the elastic action of the spring 546, thereby ensuring the cleaning effect. When the brush 544 is rotating and cleaning, the air pump 555 can be activated to deliver air through the multi-port pipe 556 and the connecting pipe 557 to multiple air pipes 552. Then, the air is sprayed downward through multiple nozzles 553 on the air pipes 552. The high-pressure airflow can blow away stubborn stains or fine particles on the top of the measuring device body 1, which is especially suitable for dry cleaning in humid environments. The timer 56 allows for the preset of appropriate time intervals to trigger the self-cleaning mechanism 5. The microcontroller 57 receives signals from the timer to control the start and stop of the micro motor 541 and the air pump 555. Through the combined action of the rotating brush 544 and the high-pressure nozzle 553, dust and debris on the top of the measuring device body 1 can be quickly and effectively removed, thus maintaining good contact of the conductive connector and improving measurement accuracy. By removing the bolts 53 on the fixing bracket 51, the self-cleaning mechanism 5 can be quickly disassembled, which is beneficial for maintenance and repair of the self-cleaning mechanism 5.
