[0037] 2) When the floating ball body moves along the guide rod, the contact wheel rotates in the present invention. The rotation of the contact wheel causes the toothed ring to drive the cleaning brush to frictionally clean the outer wall of the guide rod, effectively removing the particulate matter attached to the outer wall of the guide rod, and further ensuring that the floating ball moves stably along the outer wall of the guide rod with the water level;
[0038] 3) A contact sensor is also provided on the bearing plate in the present invention.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0047] Please refer to Figures 1-4 , a dynamic underground water level monitoring system for deep foundation pit dewatering construction based on wireless sensing, includes at least one water level acquisition module and a monitoring terminal connected thereto;
[0048] The water level acquisition module can be arranged in a deep foundation pit (such as a dewatering well for dewatering construction) to monitor the dynamic underground water level;
[0049] The water level acquisition module includes: a guide rod 1, on the outer wall of which there is a floating ball mechanism that moves along the guide rod 1 with the water level. The height of the guide rod 1 is selected according to the depth of the position to be monitored. The bottom of the guide rod 1 is provided with a bottom plate 32. When in use, the bottom plate 32 is made to contact the bottom end of the position to be monitored;
[0050] A wireless sensing detection mechanism, arranged on the guide rod 1, is used to send a warning signal to the monitoring terminal when the floating ball mechanism rises to a preset position;
[0051] The monitoring terminal is a conventional device in the art. The monitoring terminal includes a warning module for receiving the warning signal and giving a warning, etc., so that the monitoring terminal can understand and timely control the water level of the position to be monitored;
[0052] The float mechanism includes: a float body 2, a channel for the guide rod 1 to penetrate is opened at its axis, the diameter of the channel is slightly larger than the diameter of the guide rod 1, a plurality of groups of grooves 3 are opened on the inner walls of the upper and lower sides of the channel, a guide wheel 4 is slidably arranged in the groove 3, the guide wheel 4 includes a magnetic guide wheel frame and a guide wheel rotatably arranged on the outer wall of the guide wheel frame, the guide wheel 4 is connected to the bottom of the groove 3 through an elastic member 6, and the elastic member 6 is, for example, a spring;
[0053] The electromagnetic component 15 is an electromagnetic plate structure, embedded in the inner wall of the channel, and is used to energize and adsorb the guide wheel component 4 so that the guide wheel component 4 contacts the outer wall of the guide rod 1, specifically adsorbing the guide wheel frame. In normal use, the electromagnetic component 15 is energized, and the guide wheel component 4 contacts the outer wall of the guide rod 1 and cannot move horizontally, so that the float body 2 is not easy to shake on the outer wall of the guide rod 1, so that it can move up and down stably;
[0054] The anti-stuck detection mechanism is arranged on the float body 2, and is used for detecting that the float body 2 is submerged in water and driving the electromagnetic part 5 to cut off the power. The particles attached to the outer wall of the guide rod 1 make it impossible for the float body 2 to move upward on the guide rod 1 with the water level, resulting in that when the float body 2 is submerged in water, the anti-stuck detection mechanism detects it and drives the electromagnetic part 5 to cut off the power, and then the guide wheel 4 is in an active state and can move into the groove 3 to squeeze the spring. Under the cooperation of the rising buoyancy of the float body 2, the float body 2 can go over the obstacle upward, thereby alleviating or eliminating the stuck state between the float body 2 and the guide rod 1.
[0055] Preferably, the water level detection mechanism of this embodiment includes:
[0056] A top plate 22 is provided at the upper end of the guide rod 1, and a telescopic device 23 is provided on the top plate 22, and the telescopic device 23 is, for example, an electric telescopic rod;
[0057] The bearing plate 24 is slidably sleeved on the outer wall of the guide rod 1 and connected to the output end of the telescopic device 23. The bottom of the bearing plate 24 is provided with a contact sensor 25 for contacting the float body 2. The contact sensor 25 is a conventional device in the art and will not be described in detail here.
[0058] The electrical device 26 is arranged on the bearing plate 24 through the mounting frame 27. The mounting frame 27 can be installed on the top ground of the position to be monitored (for example, the top of the precipitation well). The electrical device 26 includes a housing, and a wireless communicator and a controller arranged in the housing and electrically connected to the contact sensor 25. The wireless communicator is used to enable the water level acquisition module to communicate remotely with the monitoring terminal. The controller is also electrically connected to the electromagnetic component 5 and the anti-stuck detection mechanism. The wireless communicator is also electrically connected to the monitoring terminal. The controller is used to control the electrical equipment in the water level acquisition module. When the contact sensor 25 contacts the float body 2, it sends an early warning signal to the monitoring terminal through the wireless communicator.
[0059] Preferably, a pumping device 28 electrically connected to the controller is further provided on the mounting bracket 27 of this embodiment. The pumping device 28 is, for example, a water pump. The pumping device 28 is connected with a pumping filter head 31 through a pipeline. The pumping filter head 31 is, for example, a pumping head with a filter net inside. The pumping filter head 31 is arranged on the outer wall of the floating ball main body 2. When the contact sensor 25 contacts the floating ball main body 2, the pumping device 28 is driven to open by the controller. In this way, it is possible to effectively avoid the water level in the position to be monitored from being too high, control the water level, and avoid affecting subsequent construction and other operations.
[0060] Preferably, the anti-jamming detection mechanism of this embodiment includes:
[0061] A detection cylinder 7 is embedded in the upper end of the outer wall of the floating ball main body 2. A movable block 9 is movably arranged in the detection cylinder 7. The movable block 9 is connected with a floating plate 8 through a support rod that movably penetrates the top of the detection cylinder 7. The floating plate 8 is used to move upward when the floating ball main body 2 is submerged in water;
[0062] Two groups of first detection sensors 10 are both electrically connected to the controller and are embedded in the inner wall of the detection cylinder 7 at intervals from top to bottom for detecting the position of the movable block 9. When the lower first detection sensor 10 detects the movable block 9, the controller controls the first electromagnetic member 5 to cut off the power. The first detection sensor 10 can adopt a photoelectric sensor, an infrared sensor, etc. When the floating ball main body 2 cannot rise along the outer wall of the guide rod 1 with the water level, the floating ball main body 2 will be submerged in water. At this time, the floating plate 8 drives the movable block 9 to move upward with the water level. Then, when the lower first detection sensor 10 detects the movable block 9, the power cut-off of the first electromagnetic member 5 makes the guide wheel member 4 in an active state, so that the floating ball main body 2 moves upward.
[0063] Preferably, the floating ball mechanism of this embodiment further includes:
[0064] A plurality of annular air bags 15 embedded in the outer wall of the floating ball main body 2. Adjacent two groups of annular air bags 15 are communicated with each other through a connecting pipeline 16. The annular air bags 15 can adopt rubber annular air bags 15;
[0065] A number of gas storage chambers 11 are opened inside the floating ball main body 2. The gas storage chambers 11 are filled with gas. One side of the gas storage chamber 11 is connected to an annular airbag 15 through a pipeline. A piston member 12 adapted thereto is movably arranged inside the gas storage chamber 11. The piston member 12 is a magnetic plate-like structure. An electromagnetic member two 13 for electromagnetically adsorbing the piston member 12 is arranged on one inner wall of the gas storage chamber 11. The electromagnetic member two 13 is an electromagnetic ring. The electromagnetic member two 13 is electrically connected to the controller and is used to be controlled to be energized by the controller when the upper detection sensor one 10 detects the movable block 9. When the electromagnetic member two 13 is energized, it adsorbs the piston member 12 to move and compress the gas into the annular airbag 15, causing the annular airbag 15 to expand. Initially, the annular airbag 15 is in an unexpanded state. When the water level of the floating plate 8 drives the movable block 9 upward to the upper detection sensor two, it indicates that the activation of the guide wheel member 4 does not cause the floating ball main body 2 to move upward. Then, the gas in the gas storage chamber 11 enters the annular airbag 15, causing the annular airbag 15 to expand, increasing the drainage area of the floating ball main body 2 and increasing the upward buoyancy of the floating ball main body 2, so that the floating ball main body 2 can better cross the obstacle and move upward to float out of the water surface;
[0066] An elastic guide rod 14 is arranged inside the gas storage chamber 11 and is used to drive the piston member 12 to reset when the electromagnetic member two 13 is de-energized, and pump the gas in the annular airbag 15 back into the gas storage chamber 11. The elastic guide rod 14 includes a guide rod horizontally arranged inside the gas storage chamber 11 and movably penetrating the piston member 12, and a spring sleeved on the outer wall of the guide rod, with one end connected to one inner wall of the gas storage chamber 11 and the other end connected to the piston member 12.
[0067] Preferably, a detection sensor two electrically connected to the controller is further arranged on the bottom wall of the detection cylinder 7 in this embodiment. When the detection sensor two contacts the movable block 9, the controller controls the electromagnetic member two 13 to be de-energized and the electromagnetic member one 5 to be energized. The detection sensor two is, for example, a pressure sensor, etc. When the floating ball main body 2 resumes moving upward to float out of the water surface, the floating plate 8 loses buoyancy and moves downward to reset and contact the detection sensor two under its own gravity and the gravity of the movable block 9. Then, the detection sensor two sends a signal to cause the controller to control the electromagnetic member two 13 to be de-energized and the electromagnetic member one 5 to be energized. When the electromagnetic member one 5 is energized, the guide wheel member 4 contacts the outer wall of the guide rod 1. When the electromagnetic member two 13 is de-energized, the piston member 12 pumps the gas in the annular airbag 15 back into the gas storage chamber 11.
[0068] Please refer to Figures 5-6 , preferably, the floating ball mechanism in this embodiment further includes:
[0069] The contact wheel 17 is rotatably embedded in the middle of the inner wall of one side of the channel. The contact wheel 17 is always in contact with the outer wall of the guide rod 1 and can be made of rubber material. The contact wheel 17 rotates when the float body 2 moves on the outer wall of the guide rod 1. The shaft of the contact wheel 17 is connected to a driven rod through a bevel gear set 19. The driven rod movably passes through the top of the float body 2 and extends to the top of the float body 2. The bevel gear set 19 is two sets of meshing bevel gears.
[0070] The gear ring 20 is rotatably embedded in the top of the float body 2 through a bearing and is coaxial with the guide rod 1. The gear ring 20 is movably sleeved on the outer wall of the guide rod 1 and is connected to the driven rod through the gear 18;
[0071] A plurality of cleaning brushes 21 are arranged in a circular array on the top of the gear ring 20 for cleaning the outer wall of the guide rod 1 .
[0072] When the float body 2 is upward, the contact wheel 17 rotates under the action of friction, and then drives the driven rod through the bevel gear set 19, and the driven rod drives the gear ring 20 through the gear 18, and the gear ring 20 drives the cleaning brush 21 to rub the outer wall of the guide rod 1 to clean the outer wall of the guide rod 1, effectively preventing the float body 2 from being affected by the particles attached to the outer wall of the guide rod 1 and being unable to move, thereby affecting the water level monitoring work.
[0073] Preferably, the outer wall of the guide rod 1 of the present embodiment is provided with scale lines (not shown in the figure), and an image acquisition device 30 is provided on the top of the supporting plate 24. The image acquisition device 30 is a waterproof camera. The image acquisition device 30 is used to acquire the numerical image data of the scale lines corresponding to the supporting plate 24, and send the numerical image data of the scale lines to the monitoring terminal through a wireless communicator. The monitoring terminal also includes a display module for displaying the numerical image data of the scale lines. The user can control the telescopic device 23 to adjust the supporting plate 24 to the desired position by observing the numerical image data of the scale lines, so as to realize the height regulation of the warning water level and improve the use flexibility of the water level monitoring system.
[0074] Preferably, the mounting frame 27 of this embodiment is further provided with a photovoltaic component 29, which includes a battery and a photovoltaic panel, etc., so as to supply power to the electrical equipment in the water level collection module.
