Description

Technical Field

[0001] The invention relates to the technical field of foundation pit monitoring, and in particular to an adaptive foundation pit water level monitoring device and a monitoring method thereof. Background Art

[0002] During the excavation of the construction foundation pit, when the groundwater level is higher than the bottom of the foundation pit, groundwater will continue to seep into the foundation pit. At this time, in order to ensure construction safety and avoid slope instability and other phenomena, it is necessary not only to use various drainage measures to lower the groundwater level around the foundation pit, but also to continuously monitor the foundation pit water level.

[0003] The invention patent with application number 201911253220.4 discloses a foundation pit water level detection device. In view of the problems that the existing water level detection equipment has a fixed use position, is not convenient to carry and move to a new use position, has cumbersome detection steps, and cannot visually observe the water level changes in the foundation pit, the following solution is proposed, which includes a movable seat, one side of the movable seat is fixedly connected to a mounting plate, a detection rod is provided on the top of the mounting plate, a detection plate is provided on the detection rod, a fixing hole is provided on the top of the detection plate, the detection rod is slidably installed in the fixing hole, and limit plates are fixedly installed on both sides of the detection rod, the tops of the two limit plates are in contact with the detection plate, and a plurality of floating blocks are fixedly installed on the bottom of the detection plate.

[0004] However, after actual application by technicians in this field, it was found that the above-mentioned detection equipment still has some shortcomings. The most obvious one is that the moving seat and the clamping plate are fixed at the bottom of both sides of the detection rod, and the detection plate will move up due to the action of the floating plate during the detection process. Therefore, the moving seat and the clamping plate cannot automatically adapt to the position of the detection plate, which makes it impossible to fix the detection plate later, making the reading process unable to proceed normally.

[0005] In addition, since the soil in the foundation pit will mix with the water to form muddy water, when the subsequent detection rod enters the water body of the foundation pit, some small particles of foreign matter in the soil will adhere to the surface of the detection rod and enter between the detection plate and the detection rod, causing the detection plate to get stuck when it is raised or lowered outside the detection rod, affecting the normal progress of the water level monitoring process.

[0006] Therefore, it is necessary to invent an adaptive foundation pit water level monitoring device and a monitoring method thereof to solve the above problems. Summary of the invention

The detection mechanism is triggered to release its position and reset, so as to solve the problem proposed in the above background technology that the moving seat and the clamping plate are fixed at the bottom of both sides of the detection rod, and the detection plate will move up due to the action of the floating plate during the detection process. Therefore, the moving seat and the clamping plate cannot automatically adapt to the position of the detection plate, which will lead to the subsequent inability to fix the detection plate, so that the reading process cannot be carried out normally. In addition, the soil in the foundation pit will be mixed in the water body to form muddy water, which will cause some small particles of foreign matter in the soil to adhere to the surface of the detection rod and enter between the detection plate and the detection rod when the subsequent detection rod enters the water body of the foundation pit, thereby causing the detection plate to get stuck when it is raised or lowered outside the detection rod, affecting the normal progress of the water level monitoring process.

[0022] The present invention also discloses an adaptive foundation pit water level monitoring method, which is implemented using the adaptive foundation pit water level monitoring device mentioned above. The method specifically comprises the following steps:

[0023] S1. Place the adaptive foundation pit water level monitoring device in the foundation pit, start the driving motor, and drive the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the outer sleeve guided by the guide plate to move downward. When the outer sleeve moves downward, the inner sleeve is driven downward by the first spring, and the L-shaped traction rod is driven downward by the first movable plate. When the inner sleeve moves downward, it drives the detection mechanism to move downward synchronously;

[0024] S2. As the lifting mechanism continues to move downward, the detection mechanism comes into contact with the foundation pit water. At this time, due to the buoyancy of the foundation pit water on the annular floating plate, the annular floating plate drives the detection plate to move upward, and when the detection plate moves upward, it drives the magnetic frame to move upward along the outer wall of the shell synchronously;

[0025] S3. When the reciprocating screw rotates, it drives the driving square shaft to rotate through the driving square groove. When the driving square shaft rotates, it drives the shell to rotate through the rotating disk. Centrifugal force is generated during the rotation of the shell, and small particles in the mud cannot adhere to the surface of the shell;

[0026] S4, when the outer sleeve descends to a first threshold, the bottom of the bottom plate fits with the bottom of the foundation pit, and the detection plate floats on the surface of the foundation pit water body, completing the water level measurement. At the same time, due to the obstruction of the foundation pit, the bottom plate cannot continue to descend. Subsequently, as the outer sleeve continues to descend, the first spring is continuously compressed, and the outer sleeve continues to drive the L-shaped traction rod to descend through the first movable disk;

[0027] S5. When the L-shaped traction rod descends, it drives the trigger push block to descend inside the shell. When the trigger push block descends, it drives the U-shaped push plate to descend through the connecting plate, and at the same time pushes the moving plates on both sides of the connecting plate. After being pushed, the moving plate drives multiple U-shaped push plates to move outward inside the moving channel. During the outward movement of the U-shaped push plate, the moving plate seals the space between the U-shaped push plate and the moving channel.

[0028] S6, when the outer sleeve descends to a second threshold, the outer sleeve moves to the bottom of the reciprocating thread outside the reciprocating screw, and the U-shaped push plate adjacent to the magnetic frame adheres to and adsorbs the magnetic frame, thereby completing the fixation of the magnetic frame. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves upward and resets;

[0029] S7, when the upward descending distance of the outer sleeve reaches the third threshold, the compressed first spring is reset, and as the outer sleeve continues to move upward, the outer sleeve drives the lifting mechanism to move upward synchronously through the first spring and the inner sleeve, and as the lifting mechanism continues to move upward, the top of the detection mechanism comes into contact with the bottom of the lifting column, and the lifting column continues to move upward under the push of the detection mechanism, and then the recording pen is used to continuously draw lines and mark on the inside of the transparent scale window;

[0030] S8, when the outer sleeve reaches the fourth threshold, the outer sleeve arrives at the initial position, and the water level is recorded. At this time, the top of the rotating disk is in contact with the bottom of the panel. Due to the obstruction of the panel, the rotating disk cannot continue to rise. Subsequently, as the outer sleeve continues to rise, the first spring is continuously stretched, and the first movable disk continues to drive the L-shaped traction rod to move upward. During the upward movement of the L-shaped traction rod, the U-shaped push plate is driven upward by triggering the push block and the connecting plate. When the U-shaped push plate moves upward, it pushes the outward moving plate, thereby causing the moving plate to drive the magnetic column to separate from the magnetic frame;

[0031] S9, when the outer sleeve reaches the fifth threshold, the outer sleeve reaches the top of the reciprocating thread on the outer side of the reciprocating screw, and the magnetic column is separated from the magnetic frame. Then the magnetic frame, the detection plate and the annular floating plate are reset under the action of gravity. At the same time, the lifting column also drives the recording pen and the eraser to reset under the action of gravity. During the reset of the eraser, the lines drawn by the recording pen are erased.

[0032] S10, when the outer sleeve descends to a sixth threshold, the outer sleeve reaches the initial position again, and then as the reciprocating screw continues to rotate, the outer sleeve continues to move downward, and then the next water level measurement process begins.

[0033] Technical effects and advantages of the present invention:

[0034] The present invention is provided with a shell assembly, a driving mechanism, a lifting mechanism, a detection mechanism, an adaptive fixing mechanism and a recording mechanism, so that the driving mechanism is used to drive the lifting mechanism to move downward, and then the lifting mechanism drives the detection mechanism to enter the foundation pit water body to complete water level monitoring, and then the driving mechanism triggers the adaptive fixing mechanism due to the obstruction of the bottom of the foundation pit, and then the adaptive fixing mechanism positions the detection mechanism, and when the driving mechanism subsequently drives the lifting mechanism to move upward and reset, the lifting mechanism triggers the recording mechanism through the detection mechanism, and then completes the recording of the water level height, and then due to the obstruction of the shell assembly, the driving mechanism triggers the adaptive fixing mechanism again, and then the detection mechanism is released and reset. Compared with the same type of device in the prior art, the present invention can automatically adapt to different heights of the detection mechanism, and then complete the positioning of the detection mechanism at different heights, and the reading process does not require the lifting mechanism and the detection mechanism to be disassembled, thereby reducing the difficulty of reading, and in addition, during the rotation descent and rotation ascent of the lifting mechanism, small particles of foreign matter on its surface can be peeled off to avoid the presence of foreign matter affecting the lifting and lowering of the detection mechanism, thereby ensuring the normal progress of the water level monitoring process.

[0047] like Figure 3 As shown, the driving mechanism 2 includes a reciprocating screw 21, a driving motor 22, a driving square slot 23, an outer sleeve 24, a first spring 25, an inner sleeve 26, a guide plate 27, a first movable disk 28 and an L-shaped traction rod 29, wherein the reciprocating screw 21 passes through the top of the inverted U-shaped bracket 11 and is rotatably connected to the inverted U-shaped bracket 11 through a bearing, the driving motor 22 is fixedly arranged on the top of the inverted U-shaped bracket 11 and is transmission-connected to the reciprocating screw 21, the driving square slot 23 is opened at the bottom end of the reciprocating screw 21, and the outer sleeve 24, the first spring 25 and the inner sleeve 26 are sequentially sleeved on the reciprocating screw from top to bottom. On the outside of the rod 21, the outer sleeve 24 is transmission-connected with the reciprocating screw 21, the first spring 25 is fixedly connected between the outer sleeve 24 and the inner sleeve 26, the inner sleeve 26 is slidingly connected with the reciprocating screw 21 and is slidably arranged on the inner side of the outer sleeve 24 along the vertical direction, the guide plate 27 is fixedly sleeved on the top of the outer side of the outer sleeve 24 and is slidably connected with the inner wall of the inverted U-shaped bracket 11, the first movable disk 28 is rotatably sleeved on the bottom of the outer side of the outer sleeve 24 through a bearing, and two L-shaped traction rods 29 are provided, and the two L-shaped traction rods 29 are respectively fixedly arranged on both sides of the bottom of the first movable disk 28.

[0048] By setting the above structure, the driving motor 22 can drive the reciprocating screw 21 to rotate. When the reciprocating screw 21 rotates, it drives the outer sleeve 24 guided by the guide plate 27 to move downward.

[0049] like Figure 4As shown, the lifting mechanism 3 includes a rotating disk 31, a driving square shaft 32, a shell 33, an avoidance groove 34, a moving channel 35, a second movable disk 36 and a bottom plate 37, wherein the rotating disk 31 is rotatably arranged at the bottom end of the inner sleeve 26 through a bearing and is fitted with the bottom end of the panel 12, the driving square shaft 32 is fixedly arranged at the top of the rotating disk 31 and is slidably arranged on the inner side of the driving square groove 23 along the vertical direction, the shell 33 is fixedly arranged at the bottom of the rotating disk 31, two avoidance grooves 34 are arranged, and the two avoidance grooves 34 are respectively opened at the top of both sides of the shell 33, a plurality of moving channels 35 are arranged, and the plurality of moving channels 35 are evenly opened on both sides of the shell 33, the second movable disk 36 is fixedly arranged at the bottom end of the shell 33, and the bottom plate 37 is rotatably sleeved and arranged on the outer side of the second movable disk 36 through a bearing.

[0050] By setting the above structure, when the reciprocating screw 21 rotates, the driving square slot 23 drives the driving square shaft 32 to rotate. When the driving square shaft 32 rotates, the rotating disk 31 drives the shell 33 to rotate. Centrifugal force is generated during the rotation of the shell 33, and small particles and debris in the mud cannot adhere to the surface of the shell 33. When the shell 33 is subsequently moved up and reset, it rotates synchronously, and small particles remaining on the outside of the shell 33 are also peeled off.

[0051] like Figure 4 As shown, the detection mechanism 4 includes a magnetic frame 41, a detection plate 42 and an annular floating plate 43, wherein the magnetic frame 41 is slidably sleeved on the outside of the shell 33 along the vertical direction, the detection plate 42 is fixedly sleeved on the outside of the magnetic frame 41, and the annular floating plate 43 is fixedly set at the bottom of the detection plate 42.

[0052] By setting the above structure, as the lifting mechanism 3 continues to move downward, the detection mechanism 4 comes into contact with the foundation pit water. At this time, due to the buoyancy of the foundation pit water on the annular floating plate 43, the annular floating plate 43 drives the detection plate 42 to move upward. When the detection plate 42 moves upward, it drives the magnetic frame 41 to move synchronously upward along the outer wall of the shell 33, thereby completing the water level measurement.

[0053] like Figure 5As shown, the adaptive fixing mechanism 5 includes a trigger push block 51, a connecting plate 52, a U-shaped push plate 53 and two groups of fixing components, the two groups of the fixing components are respectively attached to the two sides of the connecting plate 52, and any group of the fixing components includes a movable plate 54, a second spring 55, a plurality of magnetic columns 56 and a plurality of rubber sealing sleeves 57, wherein the trigger push block 51 is located on the inner side of the shell 33 and is fixedly connected between the two L-shaped traction rods 29, the connecting plate 52 is fixedly set at the bottom end of the trigger push block 51, the U-shaped push plate 53 is fixedly set at the bottom end of the connecting plate 52, the movable plate 54 is attached to the side of the connecting plate 52, the second spring 55 is fixedly connected between the inner wall of the shell 33 and the movable plate 54, the plurality of magnetic columns 56 are evenly fixedly set on the outer side of the movable plate 54, and the plurality of rubber sealing sleeves 57 are evenly sleeved on the outer sides of the plurality of magnetic columns 56.

[0054] By setting the above structure, when the L-shaped traction rod 29 descends, it drives the trigger push block 51 to descend inside the shell 33. When the trigger push block 51 descends, it drives the U-shaped push plate 53 to descend through the connecting plate 52, and at the same time pushes the movable plates 54 on both sides of the connecting plate 52. After being pushed, the movable plates 54 drive multiple U-shaped push plates 53 to move outward on the inner side of the movable channel 35. During the outward movement of the U-shaped push plates 53, the movable plates 54 seal the U-shaped push plates 53 and the movable channel 35. When the outer sleeve 24 moves to the bottommost end of the reciprocating thread on the outer side of the reciprocating screw 21, the U-shaped push plate 53 adjacent to the magnetic frame 41 adheres to and adsorbs the magnetic frame 41, thereby completing the fixation of the magnetic frame 41. Subsequently, as the reciprocating screw 21 continues to rotate, the outer sleeve 24 moves up and resets.

[0055] like Figure 6 As shown, the recording mechanism 6 includes a transparent scale window 61, a side panel 62, a lifting column 63, a limiting ring 64, a recording pen 65 and an erasing board 66, wherein scale lines are arranged on the outside of the transparent scale window 61, the transparent scale window 61 is fixedly nested on the side of the inverted U-shaped bracket 11, the side panel 62 is fixedly arranged in the middle of the inner side of the inverted U-shaped bracket 11, the lifting column 63 is slidably nested on the inner side of the side panel 62 along the vertical direction, the limiting ring 64 is fixedly sleeved on the outer top of the lifting column 63, and the recording pen 65 and the erasing board 66 are fixedly arranged on the side of the lifting column 63 from bottom to top.

[0056] By setting the above structure, the top of the detection mechanism 4 is in contact with the bottom of the lifting column 63. The lifting column 63 is then pushed upward by the detection mechanism 4, and the recording pen 65 is used to continuously draw lines and mark the inside of the transparent scale window 61, thereby completing the record of the water level height. The user can stand on the side of the inverted U-shaped bracket 11 to read the readings. When the detection plate 42 is subsequently reset due to gravity, the lifting column 63 also drives the recording pen 65 and the erasing plate 66 to reset under the action of gravity. During the reset process of the erasing plate 66, the lines drawn by the recording pen 65 are erased, thereby avoiding residual lines that affect the next record.

[0057] Example 2

[0058] The present invention also discloses an adaptive foundation pit water level monitoring method, which is implemented using the adaptive foundation pit water level monitoring device mentioned above. The method specifically comprises the following steps:

[0059] S1. Place the adaptive foundation pit water level monitoring device in the foundation pit, start the driving motor 22, and the driving motor 22 drives the reciprocating screw 21 to rotate. When the reciprocating screw 21 rotates, it drives the outer sleeve 24 guided by the guide plate 27 to move downward. When the outer sleeve 24 moves downward, it drives the inner sleeve 26 to move downward through the first spring 25, and drives the L-shaped traction rod 29 to move downward through the first movable plate 28. When the inner sleeve 26 moves downward, it drives the detection mechanism 4 to move downward synchronously;

[0060] S2. As the lifting mechanism 3 moves downward, the detection mechanism 4 comes into contact with the foundation pit water. At this time, due to the buoyancy of the foundation pit water on the annular floating plate 43, the annular floating plate 43 drives the detection plate 42 to move upward. When the detection plate 42 moves upward, it drives the magnetic frame 41 to move upward along the outer wall of the shell 33 synchronously.

[0061] S3, when the reciprocating screw 21 rotates, it drives the driving square shaft 32 to rotate through the driving square groove 23, and when the driving square shaft 32 rotates, it drives the shell 33 to rotate through the rotating disk 31. During the rotation of the shell 33, centrifugal force is generated, and small particles of debris in the mud cannot adhere to the surface of the shell 33;

[0062] S4, when the outer sleeve 24 descends to a first threshold, the bottom of the bottom plate 37 is in contact with the bottom of the foundation pit, and the detection plate 42 floats on the surface of the foundation pit water body, completing the water level measurement. At the same time, due to the obstruction of the foundation pit, the bottom plate 37 cannot continue to descend. Subsequently, as the outer sleeve 24 continues to descend, the first spring 25 is continuously compressed, and the outer sleeve 24 continues to drive the L-shaped traction rod 29 to descend through the first movable plate 28;

[0063] S5. When the L-shaped traction rod 29 descends, it drives the trigger push block 51 to descend inside the housing 33. When the trigger push block 51 descends, it drives the U-shaped push plate 53 to descend through the connecting plate 52, and at the same time pushes the moving plates 54 on both sides of the connecting plate 52. After being pushed, the moving plates 54 drive multiple U-shaped push plates 53 to move outward inside the moving channel 35. During the outward movement of the U-shaped push plates 53, the moving plates 54 seal the space between the U-shaped push plates 53 and the moving channel 35.

[0064] S6, when the outer sleeve 24 descends to a second threshold, the outer sleeve 24 moves to the bottom of the reciprocating thread on the outer side of the reciprocating screw 21, and the U-shaped push plate 53 adjacent to the magnetic frame 41 is attached to and adsorbed on the magnetic frame 41, thereby completing the fixation of the magnetic frame 41. Subsequently, as the reciprocating screw 21 continues to rotate, the outer sleeve 24 moves upward and resets.

[0065] S7, when the upward descending distance of the outer sleeve 24 reaches the third threshold, the compressed first spring 25 is reset, and as the outer sleeve 24 continues to move upward, the outer sleeve 24 drives the lifting mechanism 3 to move upward synchronously through the first spring 25 and the inner sleeve 26. As the lifting mechanism 3 continues to move upward, the top of the detection mechanism 4 contacts the bottom of the lifting column 63, and the lifting column 63 continues to move upward under the push of the detection mechanism 4, and then the recording pen 65 is used to continuously draw lines and mark the inside of the transparent scale window 61;

[0066] S8, when the upward and downward distance of the outer sleeve 24 reaches the fourth threshold, the outer sleeve 24 arrives at the initial position, and the water level height is recorded. At this time, the top of the rotating disk 31 is in contact with the bottom of the panel 12. Due to the obstruction of the panel 12, the rotating disk 31 cannot continue to rise. Subsequently, as the outer sleeve 24 continues to rise, the first spring 25 is continuously stretched, and at the same time, the first movable disk 28 continues to drive the L-shaped traction rod 29 to move upward. During the upward movement of the L-shaped traction rod 29, the U-shaped push plate 53 is driven upward by triggering the push block 51 and the connecting plate 52. When the U-shaped push plate 53 moves upward, it pushes the outward moving plate 54, so that the moving plate 54 drives the magnetic column 56 to separate from the magnetic frame 41;

[0067] S9, when the upward and downward distance of the outer sleeve 24 reaches the fifth threshold, the outer sleeve 24 reaches the top of the reciprocating thread on the outer side of the reciprocating screw 21, and the magnetic column 56 is separated from the magnetic frame 41. Then the magnetic frame 41, the detection plate 42 and the annular floating plate 43 are reset under the action of gravity. At the same time, the lifting column 63 also drives the recording pen 65 and the erasing plate 66 to reset under the action of gravity. During the reset process of the erasing plate 66, the lines drawn by the recording pen 65 are erased;

[0068] S10, when the descending distance of the outer sleeve 24 reaches the sixth threshold, the outer sleeve 24 reaches the initial position again, and then as the reciprocating screw 21 continues to rotate, the outer sleeve 24 continues to move downward, and then the next water level measurement process begins.

[0069] Example 3

[0070] It should also be noted that the first threshold and the second threshold increase successively, and the third threshold, the fourth threshold and the fifth threshold increase successively, and the first threshold, the second threshold, the third threshold, the fourth threshold and the fifth threshold are recorded for the convenience of accurately describing the actual working conditions of the scheme;

[0071] When the solution of the present application is actually produced, according to the actual specifications of the reciprocating screw 21, the first threshold value, the second threshold value, the third threshold value, the fourth threshold value and the fifth threshold value are all specific values.

8. An adaptive foundation pit water level monitoring method, characterized in that: The method is implemented using the adaptive foundation pit water level monitoring device as claimed in claim (7), and specifically comprises the following steps: S1. The self-adaptive foundation pit water level monitoring device is placed in the foundation pit, and the driving motor (22) is started. The driving motor (22) drives the reciprocating screw (21) to rotate. When the reciprocating screw (21) rotates, the outer sleeve (24) guided by the guide plate (27) is driven to move downward. When the outer sleeve (24) moves downward, the inner sleeve (26) is driven downward through the first spring (25), and the L-shaped traction rod (29) is driven downward through the first movable plate (28). When the inner sleeve (26) moves downward, the detection mechanism (4) is driven to move downward synchronously; S2, as the lifting mechanism (3) continues to move downward, the detection mechanism (4) comes into contact with the foundation pit water body. At this time, due to the buoyancy of the foundation pit water body on the annular floating plate (43), the annular floating plate (43) drives the detection plate (42) to move upward, and when the detection plate (42) moves upward, it drives the magnetic frame (41) to move upward along the outer wall of the shell (33) synchronously; S3, when the reciprocating screw (21) rotates, the driving square shaft (32) is driven to rotate through the driving square groove (23), and when the driving square shaft (32) rotates, the housing (33) is driven to rotate through the rotating disk (31), and centrifugal force is generated during the rotation of the housing (33), so that small particles of debris in the mud cannot adhere to the surface of the housing (33); S4, when the outer sleeve (24) descends to a first threshold, the bottom of the bottom plate (37) is in contact with the bottom of the foundation pit, and the detection plate (42) floats on the surface of the foundation pit water body, completing the water level measurement. At the same time, due to the obstruction of the foundation pit, the bottom plate (37) cannot continue to descend. Subsequently, as the outer sleeve (24) continues to descend, the first spring (25) is continuously compressed, and at the same time, the outer sleeve (24) continues to drive the L-shaped traction rod (29) to descend through the first movable plate (28); S5, when the L-shaped traction rod (29) descends, it drives the trigger push block (51) to descend inside the housing (33); when the trigger push block (51) descends, it drives the U-shaped push plate (53) to descend through the connecting plate (52), and at the same time pushes the moving plates (54) on both sides of the connecting plate (52); after being pushed, the moving plates (54) drive the multiple U-shaped push plates (53) to move outward inside the moving channel (35); during the outward movement of the U-shaped push plates (53), the moving plates (54) seal between the U-shaped push plates (53) and the moving channel (35); S6, when the outer sleeve (24) descends to a second threshold, the outer sleeve (24) moves to the bottom of the reciprocating thread on the outer side of the reciprocating screw (21), and at this time, the U-shaped push plate (53) adjacent to the magnetic frame (41) is attached to and adsorbed on the magnetic frame (41), thereby completing the fixation of the magnetic frame (41), and subsequently, as the reciprocating screw (21) continues to rotate, the outer sleeve (24) moves upward and resets; S7, when the upward descending distance of the outer sleeve (24) reaches the third threshold value, the compressed first spring (25) is reset, and subsequently as the outer sleeve (24) continues to move upward, the outer sleeve (24) drives the lifting mechanism (3) to move upward synchronously through the first spring (25) and the inner sleeve (26), and as the lifting mechanism (3) continues to move upward, the top of the detection mechanism (4) comes into contact with the bottom of the lifting column (63), and subsequently the lifting column (63) continues to move upward under the push of the detection mechanism (4), and then the recording pen (65) is used to continuously draw lines and mark the inside of the transparent scale window (61); S8, when the upward and downward distance of the outer sleeve (24) reaches the fourth threshold value, the outer sleeve (24) arrives at the initial working position, and the water level height is recorded. At this time, the top of the rotating disk (31) is in contact with the bottom of the panel (12). Due to the obstruction of the panel (12), the rotating disk (31) cannot continue to rise. Subsequently, as the outer sleeve (24) continues to rise, the first spring (25) is continuously stretched, and at the same time, the first movable disk (28) continues to drive the L-shaped traction rod (29) to move upward. During the upward movement of the L-shaped traction rod (29), the U-shaped push plate (53) is driven upward by triggering the push block (51) and the connecting plate (52). When the U-shaped push plate (53) moves upward, it pushes the outward moving plate (54), thereby causing the moving plate (54) to drive the magnetic column (56) to separate from the magnetic frame (41); S9, when the upward and downward distance of the outer sleeve (24) reaches the fifth threshold value, the outer sleeve (24) reaches the top of the reciprocating thread on the outer side of the reciprocating screw (21), and the magnetic column (56) is separated from the magnetic frame (41), and then the magnetic frame (41), the detection plate (42) and the annular floating plate (43) are reset under the action of gravity, and at the same time, the lifting column (63) also drives the recording pen (65) and the erasing plate (66) to reset under the action of gravity, and the lines drawn by the recording pen (65) are erased during the reset process of the erasing plate (66); S10, when the outer sleeve (24) reaches the sixth threshold value after the descending distance, the outer sleeve (24) reaches the initial position again, and then as the reciprocating screw (21) continues to rotate, the outer sleeve (24) continues to move downward, thereby starting the next water level measurement process.
