[0029] Please refer to Figures 1-12。A foundation pit dewatering monitoring device includes a bottom plate 1. Universal wheels 2 are installed at the bottom of the bottom plate 1. An installation frame 3 is installed on the top of the bottom plate 1. The installation frame 3 is set in a U-shaped structure. The inner top of the installation frame 3 is installed with an installation pipe 4. The top of the installation pipe 4 is installed with a support plate 5. The bottom of the installation pipe 4 is installed with a fixed pipe 7 through a connecting plate 6. A gear cylinder 8 is installed in the installation pipe 4 and the fixed pipe 7. Rotating blocks 9 are installed on both sides of the gear cylinder 8. A crank 10 is installed on the side of one group of rotating blocks 9. A locking block 11 is inserted and installed on the side of one group of rotating blocks 9. A group of insertion blocks 12 and two groups of insertion plates 13 are installed on the side of the locking block 11. A measuring plate 14 is installed inside the installation pipe 4. Tooth teeth are provided on the right side of the measuring plate 14. A slider 15 is installed on the other side of the measuring plate 14. Chute grooves adapted to the slider 15 are opened on the installation pipe 4 and the fixed pipe 7. A through groove adapted to the measuring plate 14 and the slider 15 is opened at the bottom of the fixed pipe 7. A through groove adapted to the measuring plate 14 and the slider 15 is also opened on the bottom plate 1. An observation window 16 is opened on the front of the installation pipe 4.

[0030] Preferably, four groups of universal wheels 2 are symmetrically installed at the bottom of the bottom plate 1, enabling the device to have the ability to move, so that the device can be pushed to the top of the foundation pit;

[0031] Preferably, the bottom sides of the installation frame 3 are fixedly connected to the top of the bottom plate 1. Four groups of support plates 5 are symmetrically installed on both sides of the top of the installation pipe 4. The support plates 5 are set in a right-angled triangle structure. The top of the support plates 5 is fixedly connected to the inner top of the installation frame 3, and thus the installation stability of the installation pipe 4 can be improved through the four groups of support plates 5;

[0032] Preferably, connecting plates 6 are installed on both sides of the bottom of the installation pipe 4 and both sides of the top of the fixed pipe 7. Two groups of adjacent connecting plates 6 on the installation pipe 4 and the fixed pipe 7 are connected by two groups of symmetric fixing bolts, and thus the fixed pipe 7 is installed at the bottom of the installation pipe 4;

[0033] Preferably, the two groups of rotating blocks 9 installed on both sides of the gear cylinder 8 are arranged in the installation grooves opened on both sides of the top of the fixed pipe 7 and both sides of the bottom of the installation pipe 4. The rotating blocks 9 are set in a structure with a thin middle and thick ends. The installation grooves opened at the top of the fixed pipe 7 and the bottom of the installation pipe 4 are set in a structure adapted to it, and thus a rotational connection is formed between the rotating blocks 9 and the fixed pipe 7 and the installation pipe 4, so that the gear cylinder 8 can rotate inside the fixed pipe 7 and the installation pipe 4. The tooth teeth installed on the outer side of the gear cylinder 8 are meshed with the tooth teeth installed on the right side of the measuring plate 14. The crank 10 is set in a Z-shaped structure and installed on the front of the installation pipe 4 and the fixed pipe 7. By rotating the crank 10, the gear cylinder 8 can be driven to rotate, and thus the measuring plate 14 can be driven to rise through the rotation of the gear cylinder 8, and then the measuring plate 14 is retracted into the installation pipe 4;

[0034] Preferably, the insertion block 12 is installed in the middle of the left side of the locking block 11. The insertion block 12 is inserted into a rectangular slot opened on the right side of a set of rotating blocks 9 installed on the right side of the gear cylinder 8. At the same time, two groups of insertion plates 13 are symmetrically installed on the left side of the locking block 11. One group of insertion plates 13 at the top is inserted into a slot opened at the bottom of the back surface of the installation pipe 4, and one group of insertion plates 13 at the bottom is inserted into a slot opened at the top of the back surface of the fixed pipe 7. Thus, the locking block 11 is installed on the right side of the fixed pipe 7 and the installation pipe 4. At this time, a set of rotating blocks 9 installed on the right side of the gear cylinder 8 is in a locked state and cannot rotate in the installation slots opened at the top of the fixed pipe 7 and the bottom of the installation pipe 4. Thereby, the gear cylinder 8 is in a locked state and cannot rotate. Further, the measuring plate 14 cannot move downward under the action of gravity. Further, the height of the measuring plate 14 is in a fixed state. Thus, the measuring plate 14 is stored in the installation pipe 4. When storing the device, the measuring plate 14 is always in the installation pipe 4, and the top of the measuring plate 14 is in contact with the inner top of the installation pipe 4. At this time, the locking block 11 is also installed on the back surfaces of the installation pipe 4 and the fixed pipe 7. When measuring the depth of the foundation pit, move the device to the top of the foundation pit so that the through slot on the bottom plate 1 is directly opposite to the foundation pit. At the same time, the through slot at the bottom of the fixed pipe 7 is also directly opposite to the foundation pit. Then, the locking block 11 can be removed. At this time, the rotation of the gear cylinder 8 is not restricted, and the measuring plate 14 can quickly fall downward under its own gravity and pass through the through slots opened on the fixed pipe 7 and the bottom plate 1 and enter the foundation pit. During this process, the gear cylinder 8 is always in a rotating state. After the bottom of the measuring plate 14 touches the inner bottom surface of the foundation pit, the measuring plate 14 will stop descending. At this time, the descending height of the measuring plate 14 can be observed through the observation windows 16 opened on the front and back surfaces of the installation pipe 4, so as to know the depth of the precipitation inside the foundation pit. After the measurement is completed, the measuring plate 14 can be lifted by rotating the gear cylinder 8, so as to store the measuring plate 14 in the installation pipe 4. Subsequently, install the locking block 11 to lock the measuring plate 14. When recovering the measuring plate 14, the measuring plate 14 should be cleaned through a water pipe to prevent soil from being brought into the installation pipe 4 and the fixed pipe 7;

[0035] Preferably, the length of the slider 15 installed on the left side of the measuring plate 14 is the same as the length of the teeth installed on the right side of the measuring plate 14. Chutes adapted to the slider 15 are provided on the inner left sides of the mounting pipe 4 and the fixed pipe 7. The slider 15 is arranged in a T-shaped structure. The chute provided inside the mounting pipe 4 is arranged in a rectangular structure, whose width is the same as the width of the left half of the slider 15 and greater than the width of the right half of the slider 15. The narrow side of the slider 15 is fixedly connected to the left side of the measuring plate 14. When the measuring plate 14 moves up and down, the slider 15 moves synchronously along the chutes provided on the inner sides of the mounting pipe 4 and the fixed pipe 7, ensuring that the measuring plate 14 does not shake. At the same time, the width of the teeth installed on the side of the measuring plate 14 is reserved by the through slots provided on the fixed pipe 7 and the bottom plate 1, ensuring that the measuring plate 14 can pass through the through slots provided on the fixed pipe 7 and the bottom plate 1 smoothly. The top of the slider 15 is arranged in a closed structure, and the bottom of the chute provided on the inner left side of the fixed pipe 7 is arranged in a structure adapted thereto, so that the slider 15 can descend at most until the top of the slider 15 is inside the fixed pipe 7. At this time, the slider 15 can no longer descend, and this is the maximum descending degree of the measuring plate 14, thus ensuring that the measuring plate 14 does not detach downward from the fixed pipe 7 and ensuring that the measuring plate 14 does not fall into the foundation pit.
