Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0023] Please also refer to Figure 1 and Figure 2, the monitoring and early warning system of the horizontal curtain body provided by the present invention is now described. The monitoring and early warning system of the horizontal curtain body includes a plurality of groundwater level monitoring instruments, and the groundwater level monitoring instruments include a box body 1, a positioning tube 3, a winch 4, a cable 5, a drive motor 6 and a water level meter 7. A plurality of legs 2 are fixedly connected to the box body 1, and a rolling wheel 21 is provided at the bottom of the leg 2. The positioning tube 3 is vertically arranged, and the positioning tube 3 is fixedly connected to the bottom wall of the box body 1 and is connected to the inside of the box body 1. The winch 4 is located in the box body 1 and is connected to the box body 1 for rotation around a horizontal axis. The cable 5 is wound around the winch 4, and the cable 5 passes through the positioning tube 3 so that one end of the cable 5 is located outside the box body 1. The drive motor 6 is located in the box body 1 and is used to drive the winch 4 to rotate. The water level meter 7 is connected to the end of the cable 5 located outside the box body 1.

[0024] Compared to the prior art, the horizontal curtain monitoring and early warning system provided by the present invention utilizes the rolling motion of the rolling wheels 21 on the legs 2 to support the movement of the groundwater level monitoring instrument. When the groundwater level monitoring instrument moves until the positioning tube 3 is aligned with the borehole, the drive motor 6 drives the winch 4 to rotate, thereby paying out the cable 5, and the water level meter 7 is drilled through the borehole to the groundwater for water level monitoring. When the water level meter 7 is transported to the groundwater for water level monitoring, the housing 1 protects the cable 5 on the winch 4, thereby preventing the cable 5 from being easily damaged due to lack of protection.

[0025] In some embodiments, see Figure 1 and Figure 2 The groundwater level monitoring instrument also includes a protective tube 8. This tube is sleeved over the positioning tube 3 and can be moved vertically until it contacts the ground or abuts the bottom wall of the housing 1. When the protective tube 8 moves downward to abut the ground, the positioning tube 3 and the protective tube 8 protect the cable 5 between the housing 1 and the ground.

[0026] In some embodiments, see Figure 1 The groundwater level monitoring instrument further includes two connecting units, symmetrically arranged with respect to a vertical bisector of the protective tube 8. Each connecting unit includes a connecting plate 91. Connecting plate 91 is horizontally arranged and connected to the protective tube 8. A fixing nail 92 is vertically arranged with its tip facing downward, and is inserted into connecting plate 91. When the protective tube 8 moves downward to contact the ground, the tip of the fixing nail 92 is driven into the ground, thereby restricting the movement of the groundwater level monitoring instrument.

[0027] In some embodiments, see Figure 2 and Figure 3The protective tube 8 is a square tube, and a connecting plate 91 slides through one of its side walls. The two connecting plates 91 can slide to close or open the protective tube 8. The water level measuring instrument 7 is initially located within the protective tube 8 and above the connecting plates 91. Before use, the two connecting plates 91 protect the water level measuring instrument 7 by closing the protective tube 8. Once the two connecting plates 91 slide open the protective tube 8, the water level measuring instrument 7 can be lowered.

[0028] In some embodiments, the feature connection unit can be used as follows Figure 4 See the structure shown. Figure 4 The connection unit further includes an anti-slip column 93. The anti-slip column 93 is located in the protection tube 8 and is fixedly connected to the connecting plate 91, thereby preventing the connecting plate 91 from sliding outward and detaching from the protection tube 8.

[0029] In some embodiments, the feature connection unit can be used as follows Figures 1 to 4 The structure shown. Figures 1 to 4 The connection unit also includes a connecting bolt, a limit block 94 and a connecting block 95. The limit block 94 is located outside the protective tube 8 and is fixed on the connecting plate 91. The limit block 94 is provided with a first threaded hole 941 with the axis horizontally arranged. The connecting block 95 is fixed on the bottom wall of the box body 1. The connecting block 95 is provided with a through hole 951 with the axis horizontally arranged. Among them, when the two connecting plates 91 slide to separate the protective tube 8 and the protective tube 8 abuts against the bottom wall of the box body 1, the connecting block 95 is located on the side of the limit block 94 away from the protective tube 8 and fits with the limit block 94. At this time, the screw of the connecting bolt is used to penetrate into the through hole 951 and be threadedly connected to the first threaded hole 941. The limiting of the limit block 94 by the connecting block 95 can limit the sliding of the connecting plate 91 out of the protective tube 8, so that the two connecting plates 91 maintain the state of separating the protective tube 8. The threaded connection between the screw of the connecting bolt and the first threaded hole 941 can limit the downward sliding of the protective tube 8.

[0030] In some embodiments, see Figures 1 to 4 The groundwater level monitoring instrument further includes a fixing plate 10. The fixing plate 10 is horizontally arranged and sleeved and fixed on the bottom end of the positioning tube 3. The protective tube 8 is slidably sleeved on the outside of the fixing plate 10. The fixing nail 92 can be placed on the fixing plate 10 before use, and the fixing nail 92 is prevented from being lost by the abutment between the protective tube 8 and the bottom wall of the box body 1. In this embodiment, the fixing plate 10 is located above the connecting plate 91, and the initial state of the water level measuring instrument 7 is located between the fixing plate 10 and the connecting plate 91.

[0031] In some embodiments, see Figure 2The winch 4 is provided with a first rotating shaft 110 and a second rotating shaft 120 at both ends of its rotation axis. The first rotating shaft 110 and the second rotating shaft 120 are both coaxially arranged with the rotation axis of the winch 4. Two fixing members 190 are fixed on the top wall of the housing 1. The winch 4 is located between the two fixing members 190. The first rotating shaft 110 and the second rotating shaft 120 are rotatably inserted into the two fixing members 190. The rotational connection between the winch 4 and the housing 1 is achieved through the rotational cooperation between the first rotating shaft 110 and the second rotating shaft 120 and the fixing members 190 inserted therein.

[0032] Furthermore, the drive motor 6 is fixed to the bottom wall of the housing 1. Two gears 140 are also provided within the housing 1. These gears 140 are respectively mounted and fixed to the output shaft of the drive motor 6 and the first rotating shaft 110. A synchronous toothed belt 150 is mounted on the two gears 140. The output shaft of the drive motor 6 drives the capstan 4 to rotate via the two gears 140 and the synchronous toothed belt 150.

[0033] In some embodiments, see Figure 4 The groundwater level monitoring instrument further includes a rubber sleeve 130. The rubber sleeve 130 is fixedly mounted within the positioning tube 3 and slidably mounted over the cable 5. The rubber sleeve 130 protects the outer sheath of the cable 5 from wear. Furthermore, two rubber sleeves 130 may be provided, one at each end of the positioning tube 3.

[0034] In some embodiments, see Figure 5 and Figure 6 The groundwater level monitoring instrument also includes a push-up assembly, which includes two positioning columns 160, a fixing block 170 and a push-up bolt 180. The two positioning columns 160 are arranged in parallel, and a receiving groove 1601 is provided on the end face of one end of the positioning column 160. The fixing block 170 is fixedly connected to the other end of the two positioning columns 160, and the fixing block 170 is provided with a second threaded hole, and the axis of the second threaded hole is parallel to the positioning column 160. The screw of the push-up bolt 180 is threadedly connected to the second threaded hole. Among them, the number of fixing nails 92 in the same connecting unit is two, and the two receiving grooves 1601 can be respectively sleeved on the heads of the two fixing nails 92 in the same connecting unit. At this time, the push-up bolt 180 is in a vertical state and the push-up bolt 180 can push the bottom wall of the box body 1 upward. When the two receiving grooves 1601 are respectively fitted over the heads of the two fixing pins 92 in the same connecting unit, the push bolts 180 are driven to rotate. The fixing pins 92 can restrict the fixing block 170 from rotating along with the push bolts 180, thus allowing the push bolts 180 to move vertically. When the push bolts 180 move upward, they push against the bottom wall of the box body 1, thereby pushing the tips of the fixing pins 92 into the ground.

[0035] In some embodiments, the horizontal curtain monitoring and early warning system further includes multiple strain gauges distributed within the horizontal curtain. These strain gauges measure deformation of the horizontal curtain. In this embodiment, the strain gauges can be any of a variety of existing strain gauges, such as embedded fiber Bragg grating (FBG) strain gauges, resistance strain gauges, and piezoelectric strain gauges.

[0036] Furthermore, a monitoring center can be provided, housing a control system electrically connected to the strain gauges and capable of receiving data collected by the strain gauges. The groundwater level monitoring instrument also includes a signal receiving module, whose signal input is electrically connected to one end of the cable 5 located within the housing 1, and whose signal output is electrically connected to the control system. Data collected by the water level measuring instrument 7 is transmitted to the signal receiving module via the cable 5, which then transmits the collected signal to the control system. Furthermore, the control center can include an alarm electrically connected to the control system. If the signal received by the control system indicates an anomaly, the control system controls the alarm to sound an alarm. Specifically, the control system can preset ranges for the data collected by the water level measuring instrument 7 and the strain gauges, respectively. If the data collected by the water level measuring instrument 7 or the strain gauges exceeds the corresponding preset ranges, the control system controls the alarm to sound an alarm. Multiple groundwater level monitoring instruments can be used to monitor water levels at multiple locations, and multiple strain gauges can be used to monitor deformation at multiple locations on the horizontal curtain. The monitoring values ​​from multiple groundwater level monitoring instruments and multiple strain gauges can quickly identify the location of a problem on the horizontal curtain.
