Description

Technical Field

[0001] The present application relates to the technical field of underground water level monitoring devices, and in particular to an intelligent early warning monitoring device for basement water level. Background Art

[0002] At present, in the field of civil engineering construction, it is often encountered that the basement is prone to floating due to the influence of continuous precipitation during the construction process, which can easily cause damage such as house collapse, tilt, cracks, etc. At this time, the construction unit or construction unit will use the water level intelligent early warning monitoring device to monitor the water level of the basement in real time, so that the relevant units can discover it in time and take relevant measures to minimize the occurrence of damage.

[0003] The intelligent early warning monitoring device for basement water level in the related technology mainly includes a host controller, a winding reel and a probe sensor. A tape cable is wound on the outside of the winding reel. The probe sensor is used to be electrically connected to the end of the tape cable, and the host controller is used to be electrically connected to the other end of the tape cable. The probe sensor can be a radar water level sensor, a float sensor, etc. During monitoring, the probe sensor is inserted into a pre-drilled water level hole, and the water level warning value is set through the host controller. When the probe sensor obtains that the water level value in the water level hole reaches or exceeds the water level warning value, the host controller will send a warning signal, so that relevant units can be reminded to pay attention to water level changes in time.

[0004] For the above-mentioned monitoring device, as the probe sensor is continuously extended into the water level hole, the tape measure cable will be continuously pulled out from the rotating winding reel. When the probe sensor reaches the specified depth of the water level hole, the monitoring personnel need to promptly control the winding reel to stop rotating, and then tighten the brake bolt on the winding reel to ensure that the probe sensor remains stationary. However, when the position depth of the probe sensor deviates, the monitoring personnel need to loosen the brake bolt before adjusting the depth of the probe sensor again. This repetitive process will make the entire adjustment process more cumbersome and inconvenient for the smooth progress of the adjustment work. Utility Model Content

DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The embodiment of the present application discloses an intelligent early warning monitoring device for basement water level.

[0025] Reference Figure 1, Figure 2 A basement water level intelligent early warning monitoring device includes a bracket 1, a winding reel 2 with a horizontally placed rotating axis is rotatably arranged on the bracket 1, a tape cable 3 is wound around the outside of the winding reel 2, one end of the tape cable 3 is used for connecting with a host controller signal, and the other end of the tape cable 3 is used for connecting with a probe sensor signal.

[0026] like Figure 2 , Figure 3 As shown, a ratchet 100 is coaxially fixedly mounted on the rotating shaft of the winding drum 2, and the ratchet 100 rotates synchronously with the winding drum 2. A pawl 4 is rotatably provided on the bracket 1, and its end is used to be inserted into the ratchet 100 to limit the rotation of the ratchet 100. When the end of the pawl 4 is inserted into the tooth groove on one side of the ratchet 100, the rotation of the winding drum 2 can be limited by the mutual plug-in cooperation of the pawl 4 and the ratchet 100.

[0027] like Figure 2 , Figure 3 As shown, a handle 5 mounted on the top of the winding drum 2 is fixedly mounted on one side of the bracket 1, and the handle 5 can be used for the monitoring personnel to hold, so as to facilitate the movement of the winding drum 2 or to support and fix the winding drum 2. A horizontally arranged horizontal plate 101 is fixedly mounted on the bracket 1, and the horizontal plate 101 is mounted between the handle 5 and the winding drum 2, and the length direction of the horizontal plate 101 extends along the length direction of the handle 5.

[0028] like Figure 2 , Figure 3 As shown, a control rod 6 is provided on the horizontal plate 101 to be lifted and lowered along the height direction of the bracket 1. The control rod 6 is located directly above the ratchet 4, and the lower end of the control rod 6 is linked with the ratchet 4. The upper end of the control rod 6 passes through the upper surface of the horizontal plate 101 and approaches the upper handle 5. A return spring 7 is installed on the bracket 1 at the top of the control rod 6, and the return spring 7 is extended and retracted along the lifting direction of the control rod 6.

[0029] like Figure 2 , Figure 3 As shown, the upper end of the return spring 7 contacts the outer side wall of the bracket 1, and the lower end of the return spring 7 contacts the top side wall of the control rod 6 after passing through the upper surface of the horizontal plate 101. In a natural state, the return spring 7 is used to apply downward pressure to the control rod 6, thereby forcing the control rod 6 to move toward the direction close to the lower pawl 4, so that the end of the pawl 4 is stably and firmly inserted and pressed into the tooth groove of the ratchet 100.

[0030] like Figure 2 , Figure 3As shown, the upper surface of the horizontal plate 101 is also provided with a lifting seat 8 located directly below the handle 5, and the lifting seat 8 is movably arranged on the horizontal plate 101 along the lifting direction of the control rod 6. A limiting hole 81 for the palm to be inserted is passed through the lifting seat 8, and a linkage rod 80 is fixedly connected to the end of the lifting seat 8 facing the control rod 6, and the end of the linkage rod 80 away from the lifting seat 8 is linked with the control rod 6. When it is necessary to release the lock of the winding drum 2, the monitoring personnel inserts the palm into the limiting hole 81, and then holds the handle 5 to pull the lifting seat 8 upward. As the lifting seat 8 is lifted upward, the control rod 6 can be lifted upward synchronously under the drive of the linkage rod 80. When the end of the pawl 4 is smoothly rotated out of the tooth groove of the ratchet 100 under the drive of the control rod 6, the lock of the winding drum 2 can be successfully released. The entire unlocking process is completed in one step, which is convenient and quick.

[0031] like Figure 2 , Figure 3 As shown, a threading ring 82 located below the horizontal plate 101 is fixedly installed at the bottom of the lifting seat 8, and the threading ring 82 is used for passing the tape cable 3 after being pulled out from the winding disk 2. The tape cable 3 is inserted into the threading ring 82, and the threading ring 82 can guide the tape cable 3, ensuring that the tape cable 3 can be pulled out from the specified position of the winding disk 2, reducing the position deviation of the tape cable 3 during the pulling process, thereby further improving the stability of the probe sensor when it descends in the water level hole.

[0032] like Figure 2 , Figure 3 As shown, a turning handle 20 is eccentrically fixedly provided on the outer wall of the winding drum 2, and the turning handle 20 is convenient for monitoring personnel to turn the winding drum 2. A fastening locking column 9 is threadedly connected on the other outer wall of the bracket 1 away from the turning handle 20, and a rubber pad 90 facing the outer wall of the winding drum 2 is fixedly sleeved at the end of the fastening locking column 9. When the fastening locking column 9 is tightened, the rubber pad 90 will gradually approach the outer wall of the winding drum 2, and finally the rubber pad 90 will conflict with the outer wall of the winding drum 2, so that the winding drum 2 can be locked more stably and securely, so that the winding drum 2 can no longer rotate.

[0033] like Figure 1 , Figure 2 As shown, a track 10 located below the winding drum 2 is fixedly mounted on the bracket 1, and the length of the track 10 extends in the horizontal direction. A receiving seat 11 is arranged outside the track 10, and the receiving seat 11 is slidably arranged on the track 10 along the length direction of the track 10. A support frame 12 is accommodated in the receiving seat 11, and one end of the support frame 12 is rotatably arranged on the inner side wall of the receiving seat 11, and a guide wheel 13 is rotatably arranged on the other end of the support frame 12.

[0034] like Figure 1 , Figure 2As shown, an opening is formed on the upper surface of the accommodating seat 11, and the guide wheel 13 can be rotated out of the accommodating seat 11 through the upper opening following the support frame 12. The guide wheel 13 is used for placing the tape measure cable 3 and erecting it on the support frame 12 to further support and guide the tape measure cable 3. A fastener 14 for tightening and fixing the support frame 12 on the accommodating seat 11 is threadedly connected on the rotating shaft between the support frame 12 and the accommodating seat 11. In this embodiment, the fastener 14 is a butterfly bolt. After the support frame 12 is rotated to a suitable angle, the support frame 12 is fixed by tightening the fastener 14, and the stability of the support frame 12 during support can be ensured.

[0035] The implementation principle is: lift the lifting seat 8 away from the ratchet 100 to overcome the elastic force applied by the reset spring 7 to the control rod 6, until the control rod 6 drives the lower pawl 4 and the ratchet 100 to separate from each other, at which time the pawl 4 can release the lock on the winding drum 2, and in this state the tape cable 3 can be smoothly pulled out from the winding drum 2. When the probe sensor reaches the specified depth of the water level hole, it is only necessary to remove the external force applied to the control rod 6. At this time, the control rod 6 will push the pawl 4 downward into the outer ring tooth groove of the ratchet 100 under the elastic force of the reset spring 7. Through the mutual plug-in cooperation of the pawl 4 and the ratchet 100, the rotation of the winding drum 2 can be restricted, and the winding drum 2 can be locked again; the entire locking process is completed in one step, which is convenient for the purpose of repeatedly adjusting the position depth of the probe sensor, and the adjustment process is convenient and fast.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
