However, the bottom of the foundation pit is not flat, which causes the image acquisition device to be not in a horizontal state. Therefore, the second knob 11 is loosened at this time, and the telescopic sleeve 10 can slide on the outside of the diagonal support rod 4, thereby changing the overall length of the diagonal support rod 4 and the telescopic sleeve 10. The spirit level 13 is used to determine whether the fixed plate 12 is in a horizontal state. If not, continue to adjust. After the adjustment is completed, lock the second knob 11 to ensure that the image acquisition body 15 is in a horizontal state, thereby improving the accuracy of image acquisition.

[0020] The outer sleeve of the support rod 2 is provided with a sliding sleeve 6, and the sliding sleeve 6 is slidably installed with the sliding sleeve 6 along the length direction of the support rod 2. The outer thread of the sliding sleeve 6 is connected with a first knob 7, and the sliding sleeve 6 is fixed to the support rod 2 by locking the first knob 7. The outside of the three diagonal support rods 4 and above the telescopic sleeve 10 are fixedly installed with a fixing sleeve 5. The top of the mounting plate 1 is equidistantly provided with grooves 9, and the number of the grooves 9 is three. The bottom end of the sliding sleeve 6 is equidistantly provided with connecting rods 8 for rotation, and the number of the connecting rods 8 is three, and one end of the three connecting rods 8 is divided into The three fixed sleeves 5 are rotatably installed. When unfolding the diagonal support rod 4, first loosen the first knob 7 so that the sliding sleeve 6 can slide along the length direction of the support rod 2, and move the sliding sleeve 6 to the bottom end. In this process, since the connecting rod 8 is rotatably installed with the fixed sleeve 5 and the sliding sleeve 6 respectively, the three diagonal support rods 4 are unfolded together, and then the first knob 7 is locked to fix the sliding sleeve 6. When it needs to be stored, loosen the first knob 7, slide the sliding sleeve 6 upward, and the three diagonal support rods 4 are retracted to the inside of the groove 9, thereby reducing the volume for easy carrying and transportation.

In this process, since the connecting rod 8 is rotatably installed with the fixed sleeve 5 and the sliding sleeve 6 respectively, the three diagonal support rods 4 are unfolded together, and then the first knob 7 is locked to fix the sliding sleeve 6, and the telescopic sleeve 10 contacts the ground, thereby supporting the image acquisition device. The bottom of the foundation pit is not flat, resulting in the image acquisition device not being in a horizontal state. Therefore, the second knob 11 is loosened at this time, and the telescopic sleeve 10 can slide on the outside of the diagonal support rod 4, thereby changing the overall length of the diagonal support rod 4 and the telescopic sleeve 10, and judging whether the fixed plate 12 is in a horizontal state according to the spirit level 13. If not, continue to adjust. After the adjustment, lock the second knob 11 to ensure that the image acquisition body 15 is in a horizontal state, thereby improving the accuracy of image acquisition.

[0024] Step 2: Slide and install the image acquisition body 15 and the fixed plate 12 through the slide groove 14, and then slide the slider 16 so that the slider 16 blocks the image acquisition body 15. The structure is simple and convenient for installation or disassembly. The image acquisition body 15 is a widely used device, so it is not described here. When it needs to be stored, loosen the first knob 7, slide the sliding sleeve 6 upward, and the three diagonal support rods 4 are retracted into the inside of the groove 9, thereby reducing the volume and facilitating carrying and transportation.

[0025] Compared with the related art, the foundation pit monitoring image acquisition device for construction supervision provided by the utility model has the following beneficial effects:

[0026] When placing the image acquisition device, first rotate and unfold the diagonal support rod 4, and the telescopic sleeve 10 contacts the ground to support the image acquisition device. However, the bottom of the foundation pit is not flat, which causes the image acquisition device to be not in a horizontal state. Therefore, the second knob 11 is loosened at this time, and the telescopic sleeve 10 can slide on the outside of the diagonal support rod 4, thereby changing the overall length of the diagonal support rod 4 and the telescopic sleeve 10. The spirit level 13 is used to determine whether the fixed plate 12 is in a horizontal state. If not, continue to adjust. After the adjustment is completed, lock the second knob 11 to ensure that the image acquisition body 15 is in a horizontal state, thereby improving the accuracy of image acquisition.
