Description

Technical Field

[0001] This invention belongs to the field of observation after high-pressure gas-liquid two-phase jet impact depressurization, and relates to an observation system and method for using high-pressure gas-liquid two-phase jet impact depressurization. Background Technology

[0002] High-pressure gas-liquid two-phase jet devices can fracture rocks using jets, thereby achieving mining objectives. Currently, the vast majority of high-pressure gas-liquid two-phase jet impact depressurization devices in China operate on a cycle of initial perforation, intermediate reaming, and final hole washing. After the initial perforation, high-pressure gas-liquid two-phase jets are used to complete the reaming operation. After the intermediate reaming, high-pressure gas is used to wash the borehole, and the cycle repeats after washing. Because it is difficult to observe changes in borehole diameter during high-pressure gas-liquid two-phase jet operations, rapid monitoring of the operation is impossible, hindering quick assessment of the operational status.

[0003] Currently, most methods rely on manual estimation of orifice diameter changes during high-pressure gas-liquid two-phase jet operations. While this method is simple, its accuracy is poor. To improve the observation of orifice diameter changes during high-pressure gas-liquid two-phase jet operations and thus facilitate mining operations, this invention provides an observation system after high-pressure gas-liquid two-phase jet impact depressurization. Summary of the Invention

[0014] The second cover is provided with a third semi-circular slot, a fourth semi-circular slot, a third partition, and a fourth partition;

[0015] The outer ring of the first bearing engages between the first semicircular groove and the third semicircular groove, and the outer ring of the second bearing engages between the second semicircular groove and the fourth semicircular groove.

[0023] Specifically, the present invention also provides a method for using an observation system after high-pressure gas-liquid two-phase jet impact depressurization, comprising the following steps:

[0024] S1: After the high-pressure gas-liquid two-phase jet impact depressurization, the user logs into the cloud platform via a mobile terminal and activates the first light strip, the second light strip, and the second motor via the controller. The second motor drives the active rotating block to rotate, and the active rotating block drives the first driven rotating block and the second driven rotating block to rotate. The first telescopic plate and the second telescopic plate move in opposite directions, and the camera receives light.

[0025] S2: Then the controller turns on the first motor and the camera. The first motor drives the first drive gear and the second drive gear to rotate through the shaft. Then the first cover and the second cover rotate between the first bearing and the second bearing.

[0026] S3: During the rotation process, the brush cleans the impurities on the transparent protective shell. After cleaning, the controller controls the camera to take pictures of the aperture and uploads the pictures to the cloud platform through the 4G module.

[0027] S4: The cloud platform sends the photos to the mobile terminal for analysis. After the shooting is completed, the controller turns off the camera, the first light strip, and the second light strip, and controls the first motor to stop rotating and the second motor to reset. At this time, the second motor drives the active rotating block to rotate, and the active rotating block drives the first driven rotating block and the second driven rotating block to rotate. The first telescopic plate and the second telescopic plate shield the moving camera from the light.

[0028] The beneficial effects of this invention are:

[0029] 1. After the high-pressure gas-liquid two-phase jet impacts and depressurizes, the user logs into the cloud platform via a mobile terminal, activates the camera via the controller to take a picture of the aperture, and uploads it to the cloud platform. The cloud platform then sends the picture to the mobile terminal, thus enabling convenient and quick observation of the aperture and greatly improving the accuracy of the observation.

[0030] 2. By setting up a dustproof device, dust can be prevented from adhering to the camera through the aperture, thus ensuring the camera's shooting effect.

[0031] 3. By setting a first motor, the first motor drives the first drive gear and the second drive gear to rotate. Since the first gear ring and the second gear ring are fixed, the first cover and the outer ring of the first bearing and the second bearing are engaged, so that the first cover and the second cover can rotate 360°, realizing the effect of 360° shooting by the camera.

[0032] 4. By setting a transparent protective shell, the system can prevent water from entering the controller, battery, camera and other equipment when subjected to high-pressure gas-liquid two-phase jet impact, thus protecting the equipment.

[0033] 5. By incorporating a dust removal component, the brushes within the component can remove impurities from the transparent protective shell as the first and second covers rotate, thereby ensuring the clarity and accuracy of the camera's images. Attached Figure Description

[0070] like Figure 20 As shown, specifically, the present invention also provides a method for using an observation system after high-pressure gas-liquid two-phase jet impact depressurization, comprising the following steps:

The second motor drives the active rotating block to rotate, and the active rotating block drives the first driven rotating block and the second driven rotating block to rotate. The first telescopic plate and the second telescopic plate move in opposite directions, and the camera receives light.

[0072] S2: Then the controller turns on the first motor and the camera. The first motor drives the first drive gear and the second drive gear to rotate through the shaft. Then the first cover and the second cover rotate between the first bearing and the second bearing.

[0073] S3: During the rotation process, the brush cleans the impurities on the transparent protective shell. After cleaning, the controller controls the camera to take pictures of the aperture and uploads the pictures to the cloud platform through the 4G module.
