Description

Technical Field

[0001] The utility model belongs to the technical field of detection, and relates to a road disease detection device for urban engineering geophysical exploration, in particular to a drilling camera device for verifying the development direction of underground disease bodies. Background Art

[0002] Road collapse accidents often occur under urban roads, in areas with dense underground water pipelines, and in areas affected by rail transit construction. In order to prevent road collapse accidents, it is necessary to detect and verify the underground diseased bodies under the roads.

[0003] In the detection of underground disease bodies, the detected cavities and hollow diseases need to be verified. The existing verification method is to use an endoscope device to record in the borehole. When the endoscope is lowered to the top of the underground disease body, a mark is made on the connecting line of the endoscope. When the endoscope is lowered to the bottom of the underground disease body, a mark is made on the connecting line again. The two marks are measured with a ruler to determine the depth of the top and bottom of the underground disease body.

[0004] This verification method usually has the following two problems: 1. The video recorded by the existing endoscope equipment does not have a direction, and it is impossible to know the development direction of the underground disease body (cavity, hollowing) underground; 2. The endoscope connecting line is a soft line. When lowering the endoscope, it is impossible to ensure that the connecting line is tight and vertical. Directly measuring the marks on the connecting line to determine the depth of the top and bottom of the underground disease body will result in errors. Utility Model Content

[0022] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the utility model provides a drilling camera device for verifying the development direction of underground disease bodies, which is used to verify the cavities and hollow underground disease bodies under the borehole, and includes a probe rod 1, a probe 2, a data line 3, a pulley-depth counter 4 and a host 5.

[0024] The probe 2 is fixed at the bottom end of the probe rod 1 and is threadedly connected to the probe rod 1. Figure 2 As shown, the probe 2 includes a gyroscope 21, a 360° panoramic micro camera 22 and an LED light source 23. The probe 2 is inserted into the borehole along with the probe rod 1 to detect it. Specifically, in the probe 2, there are two LED light sources 23, which are respectively fixed on the upper and lower sides of the 360° panoramic micro camera 22, and the gyroscope 21 is fixed above the upper LED light source 23.

[0025] One end of the data line 3 passes through the probe rod 1 and is connected to the gyroscope 21 and the 360° panoramic micro camera 22, and the other end is connected to the host 5. Under the illumination of the LED light source 23, the 360° panoramic micro camera 22 can clearly capture the situation in the borehole, including the internal structure and size of the underground disease body (empty, hollow), and transmit it to the host 5 through the data line 3; at the same time, the gyroscope 21 can obtain the direction of the video shot by the 360° panoramic micro camera 22 in real time, and transmit it to the host 5 through the data line 3.

[0026] The pulley-depth counter 4 is fixed outside the borehole. The middle part of the data line 3 is placed on the pulley of the pulley-depth counter 4. When the probe 2 is inserted into the borehole, the data line 3 moves accordingly and drives the pulley-depth counter 4 to rotate and count. By recording the number of rotations of the pulley and combining the pulley diameter, the length of the data line 3 movement, that is, the depth of the data line 3 inserted into the borehole can be calculated. The pulley-depth counter 4 is connected to the host 5, and the counting information is transmitted to the host 5. The host 5 calculates the depth of the data line 3 inserted into the borehole. At the same time, combined with the real-time picture taken by the 360° panoramic miniature camera 22, a video picture inside the borehole with actual depth information can be obtained. The pulley-depth counter 4 is a prior art. For example, the JK76 meter meter of Shanghai Jiakong can be used as a pulley-depth counter for this device.

[0027] Specifically, the probe rod 1 is composed of a plurality of sub-probe rods 11 connected end to end. By adding sub-probe rods 11, the length of the probe rod 1 is extended, that is, the depth of the probe rod 1 entering the borehole is increased, so that the probe 2 is gradually lowered to the required depth.

[0028] The device also includes a bracket 6 fixed outside the drill hole. Figure 3 and 4 As shown, two intercepting rods 61 are fixed on the bracket 6, which are arranged in parallel front and back and extend to the top of the borehole. Support rods 12 are fixed on the opposite sides of the top of the sub-probe rod 11, that is, the support rods 12 on both sides form a T-shaped structure with the rod body of the sub-probe rod 11. The rod body of the sub-probe rod 11 can pass between the two intercepting rods 61 and be placed on the intercepting rod 61 through the support rods 12, that is, by making the support rod 12 and the intercepting rod 61 at a certain angle, it is placed on the intercepting rod 61, so that it is convenient to connect a new sub-probe rod 11 above the sub-probe rod 11. At the same time, the width of the support rod 12 is less than the spacing between the two intercepting rods 61, so that after the new sub-probe rod 11 is connected, the sub-probe rod 11 can be rotated to make the support rod 12 pass between the two intercepting rods 61 at an angle parallel to the intercepting rod 61, and then continue to lower the probe rod 1.

[0029] The support 6 is provided with a weight 62 pressed on the bottom thereof, so that the existing probe rod 1 can be stably supported when a new sub-probe rod 11 is connected.

[0030] The sub-probe rods 11 are connected by threads. Specifically, each sub-probe rod 11 has an internal thread at the top and an external thread at the bottom, and the upper sub-probe rod 11 is fixedly connected by screwing the bottom end into the top of the lower sub-probe rod 11, and this connection method does not affect the setting of the support rod 12.

[0031] like Figure 5 As shown, the height of the pulley-depth counter 4 is higher than the sum of the height of one sub-probe rod 11 and the distance from the interception rod 61 to the borehole opening. That is, after the sub-probe rod 11 placed on the interception rod 61 is connected with the new sub-probe rod 11, the pulley-depth counter 4 is higher than the top of the new sub-probe rod 11, so that when it is further lowered, the data line 3 placed on the pulley-depth counter 4 can still drive the pulley-depth counter 4 to rotate and count.

[0032] In a preferred embodiment, the outer surface of the probe rod 1 has scales arranged along its length. Combined with the image captured by the 360° panoramic micro camera 22 displayed in real time by the host 5, when the required measurement depth is required, for example, when lowered to the top, bottom, the position with the largest development scale and the position with the smallest development scale of the underground disease body (empty, hollow), the scales on the surface of the probe rod 1 are directly read to verify the depth calculated by the pulley-depth counter 4 at the corresponding position.

[0033] The working principle of the borehole camera device for verifying the development direction of underground disease bodies is as follows: the probe 2 is inserted into the borehole for detection through the probe rod 1. Under the illumination of the LED light source 23, the 360° panoramic micro camera 22 captures the situation in the borehole including the internal structure and size of the underground disease bodies (hollowness, voids), and transmits it to the host 5 via the data line 3. At the same time, the gyroscope 21 obtains the orientation of the video shot by the 360° panoramic micro camera 22 in real time, and transmits it to the host 5 via the data line 3, thereby obtaining an underground video picture with orientation information.

[0034] At the same time, the lowered probe 2 drives its data cable 3 to gradually extend into the borehole. During this process, the data cable 3 placed on the pulley of the pulley-depth counter 4 drives its rotation count and transmits it to the host 5. The host 5 calculates the distance moved by the data cable 3 based on the diameter of the pulley, which is the depth of the probe 2 entering the borehole, thereby obtaining an underground video picture with depth information.

[0035] Specifically, one end of the data cable 3 is inserted into the first sub-probe 11 and connected to the probe 2 (360° panoramic micro camera 22 and gyroscope 21) at its bottom, and the other end is connected to the host 5. The first sub-probe 11 is manually vertically placed above the borehole, and the data cable 3 is placed on the pulley of the pulley-depth counter 4. The probe 2 is lowered at a constant speed manually. When the probe 2 enters the borehole, the pulley-depth counter 4 is started to count. When the first sub-probe rod 11 is lowered to the point where its support rod 12 rests on the interception rod 61 of the bracket 6, the counting is paused, and then the data line 3 is disconnected from the host 5, and the second sub-probe rod 11 is passed through. Under the support of the bracket 6, the second sub-probe rod 11 is connected to the first sub-probe rod 11, and then the data line 3 is placed on the pulley of the pulley-depth counter 4 again, and the probe rod 1 is rotated so that the support rod 12 of the first sub-probe rod 11 is rotated to a position where it can pass through the two interception rods 61, and then the probe rod 1 is continued to be lowered, and the pulley-depth counter 4 is started again to continue counting. Since the pulley-depth counter 4 is higher than the top of the second sub-probe rod 11 at this time, the pulley-depth counter 4 can still count when it continues to be lowered at this position. During the counting process, it is sufficient to ensure that the data line 3 between the pulley-depth counter 4 and the probe 2 is in a straight state. Finally, a new sub-probe rod 11 is connected in the same way until the detection of the required verification positions such as the top, bottom, the position with the largest development scale and the position with the smallest development scale of the underground disease body (empty space, cavity) is completed.

[0036] Among them, the images captured by the 360° panoramic micro camera 22 are displayed in real time by the host 5. At the required verification positions such as the top, bottom, largest development scale and smallest development scale of the underground disease body (void, cavity), the scale on the surface of the probe rod 1 is directly read manually, and the length of the probe 2 is added to the depth of the position, which is used to verify the depth calculated by the counting of the pulley-depth counter 4 at this time.
