[0002] The foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. When excavating the foundation pit, if the groundwater level is higher than the excavation bottom surface, groundwater will continue to flow into the foundation pit, causing a series of unnecessary troubles to the foundation pit project. Therefore, in order to ensure that the foundation pit can be constructed normally, precipitation work is usually required.

[0003] Regarding the existing related technologies, the inventors believe that the following defects often exist: conventional foundation pit dewatering equipment in the existing technology requires manpower to go to the site to check the dewatering situation and record the data, which requires a large investment in human resources. In addition, when the water level is lower than the drainage pipe of the water pump, if the water pump is not turned off in time, the water pump is prone to long-term reactive operation and cause damage.

[0004] To this end, the present invention provides intelligent monitoring and control equipment for foundation pit dewatering. Summary of the Invention

The water level in the downpipe is monitored by a water level sensor, and the data processing module analyzes and processes the water level data after receiving it. Then, the network communication module can remotely transmit the data information to the external IoT terminal device. The staff can query the drainage level information in real time through the terminal APP and other intelligent software, which can simplify the manual inspection process and reduce maintenance costs. When the water level is lower than the lower end of the drain pipe, the network communication module can send an alarm signal to the terminal, which is convenient for the staff to respond quickly and can turn on or off the water pump on the terminal, thereby achieving the purpose of intelligent control and preventing the water pump from being damaged due to long-term reactive operation.

By providing multiple dividing strips 14, a separation area is formed on the surface of the conveyor belt 11 between adjacent dividing strips 14, which can increase the friction between the conveyor belt 11 and the mud and sand, thereby improving the efficiency of carrying mud and sand out.

By providing the cleaning rod 22 and the bristles 23, the bristles 23 can rub and scrape the surface of the conveyor belt 11, which is conducive to scraping off the compacted mud and sand.

[0036] The conveying cylinder 9 is fixedly connected to a rotating shaft 24, and the rotating shaft 24 is rotatably connected to the end plate 12; a group of transmission plates 25 are evenly distributed on the circumference of the surface of the rotating shaft 24; the inner side of the end plate 12 is fixedly connected to an elastic block 27 through a connecting plate 26, and the elastic block 27 is located above the transmission plate 25; air is stored in the elastic block 27; the guide rod 21 and the cleaning rod 22 are in sliding connection; the surface of the mounting plate 20 is fixedly connected to a fixed sleeve 28; the fixed sleeve 28 is internally connected to a movable column 29 in a sliding sealing manner, and the movable column 29 is fixedly connected to the cleaning rod 22; a spring is fixedly connected between the fixed sleeve 28 and the movable column 29; the elastic block 27 and the fixed sleeve 28 are connected by a conduit 30; in the process of the conveying cylinder 9 driving the rotating shaft 24 to rotate, the transmission plate 25 will successively pass over and squeeze the surface of the elastic block 27, and then the air in the elastic block 27 will be squeezed into the interior of the fixed sleeve 28 through the conduit 30, pushing the movable column 29 to extend outward and driving the cleaning rod 22 to slide along the guide rod 21. When the transmission plate 25 is disengaged from the elastic block 27, the spring pulls the movable column 29 and the cleaning rod 22 to reset, and then the air in the fixed sleeve 28 returns to the interior of the elastic block 27.

[0037] Example 2:

[0038] like Figure 6As shown, compared with Example 1, another embodiment of the present invention is: the dividing strip 14 is made of elastic material; a cavity 31 is provided inside the dividing strip 14; an elastic member 32 is fixed between the top wall of the cavity 31 and the conveyor belt 11; a group of guide holes 33 are evenly distributed on one side of the bottom of the dividing strip 14, and the guide holes 33 are connected to the cavity 31; water can enter the cavity 31 through the guide holes 33, and when the roller 17 squeezes the dividing strip 14, the water in the cavity 31 can be squeezed outward through the guide holes 33, and the extrusion direction is the surface of the conveyor belt 11 that has been rolled by the roller 17 before, impacting the compacted mud and sand, and further breaking up the mud and sand, and cooperating with the bristles 23, the mud and sand can be cleared in multiple directions and angles.

[0039] A guide piece 34 is fixedly connected to the surface of the dividing strip 14 near the position above the guide hole 33; the guide piece 34 is arranged to be arc-shaped, and the concave surface of the guide piece 34 faces the conveyor belt 11; by setting the guide piece 34, the direction of the sprayed water flow can be limited, and the water flow can be further guided to the surface of the conveyor belt 11, thereby increasing the impact force.

[0040] Working principle: The sand filter pipe 4 in the present invention is located inside the aquifer below the foundation pit. The groundwater in the aquifer enters the sand filter pipe 4 and the downpipe 3 through the side wall of the sand filter pipe 4, and then the water is pumped out by the water pump 2 and the drainage pipe 5 to realize the dewatering of the foundation pit. The water level height in the downpipe 3 is monitored by the water level sensor 6. The data processing module analyzes and processes the water level data after receiving it, and then the network communication module can remotely transmit the data information to the external Internet of Things terminal equipment. The staff can query the drainage level information in real time through the terminal APP and other intelligent software, which can simplify the process of manual inspection and reduce maintenance costs. When the water level is lower than the lower end of the drainage pipe 5, the network communication module The communication module can send an alarm signal to the terminal, which is convenient for the staff to respond quickly. The water pump 2 can be turned off or on on the terminal, thereby achieving the purpose of intelligent control and preventing the water pump 2 from being damaged due to long-term reactive operation; the flow information of the drainage pipe 5 is monitored by the flow sensor 7, and the staff can query the flow information through the terminal to judge and analyze the operating status of the water pump 2, and further control the operating status of the equipment and the on-site situation; part of the mud and sand in the aquifer will enter the interior of the sand filter pipe 4 through the side wall of the sand filter pipe 4, and the mud and sand with small particles will be sucked away by the drainage pipe 5, while the mud and sand with large particles will easily sink. Over time, a large amount of sand will form at the bottom of the sand filter pipe 4, and the drainage pipe 5 will be drained away. The end of the pipe 5 is buried, resulting in a problem of reduced pumping efficiency of the drainage pipe 5. At this time, the present invention drives the conveying drum 9 and the conveyor belt 11 to rotate through the motor 10, and then continuously conveys the mud and sand falling downward through the side trough 8 to the outside, thereby reducing the large amount of mud and sand deposited at the bottom of the sand filter pipe 4 and eventually burying the end of the drainage pipe 5; by setting the baffle 13, the gap between the conveyor belt 11 and the side wall of the sand filter pipe 4 can be blocked, which can reduce the mud and sand from settling below the conveyor belt 11 through this gap and causing the mud and sand to be difficult to discharge. By setting a plurality of dividing strips 14, a separation area is formed on the surface of the conveyor belt 11 between adjacent dividing strips 14, which can increase the distance between the conveyor belt 11 and the side wall of the sand filter pipe 4. The friction between the mud and sand improves the efficiency of carrying the mud and sand outward; by setting the blocking plate 15, the top of the side trough 8 can be blocked to prevent the external mud and sand from entering the sand filter tube 4 through the top of the side trough 8 in large quantities, and the roller bar 17 can roll on the surface of the conveyor belt 11, so that when the mud and sand on the surface of the conveyor belt 11 passes through the blocking plate 15, the retention of the mud and sand can be reduced, so that the mud and sand can be discharged smoothly. When the roller bar 17 contacts and squeezes the dividing bar 14, the roller bar 17 can be squeezed into the inside of the chute 1. Through the cooperation of the compression spring 16, the roller bar 17 can adapt to the unevenness of the surface of the conveyor belt 11, so that the roller bar 17 can smoothly pass through the dividing bar 14 or accumulated mud and sand.By setting the blocking plate 2 18, the bottom of the side trough 8 can be blocked to prevent the external mud and sand from entering the sand filter tube 4 through the bottom of the side trough 8 in large quantities, and the blocking plate 2 18 can scrape the mud and sand on the surface of the conveyor belt 11 to prevent the conveyor belt 11 from bringing the external mud and sand into the sand filter tube 4. Through the cooperation of the compression spring 2 19, the roller 17 can adapt to the uneven surface of the conveyor belt 11, so that the roller 17 can pass through the dividing strip 14 smoothly; because the roller 17 rolls on the surface of the conveyor belt 11, it is easy to convey the conveyor belt 11. The mud and sand on the surface of the belt 11 are rolled and compacted, making it difficult for the mud and sand to be separated from the conveyor belt 11 smoothly. By setting the cleaning rod 22 and the bristles 23, the bristles 23 can rub and scrape the surface of the conveyor belt 11, thereby facilitating the scraping of the compacted mud and sand; in the process of the conveying cylinder 9 driving the rotating shaft 24 to rotate, the transmission plate 25 will successively pass through and squeeze the surface of the elastic block 27, and then the air in the elastic block 27 will be squeezed into the interior of the fixed sleeve 28 through the conduit 30, pushing the movable column 29 outward, and driving the cleaning rod 22 along As the guide rod 21 slides, when the transmission plate 25 disengages from the elastic block 27, the spring pulls the movable column 29 and the cleaning rod 22 to reset, and then the air in the fixed sleeve 28 returns to the inside of the elastic block 27, and the circulation is carried out in this way, so that the cleaning rod 22 continuously drives the bristles 23 to reciprocate, thereby improving the efficiency of the bristles 23 in scraping mud and sand, and reducing the residual mud and sand on the surface of the conveyor belt 11; water can enter the cavity 31 through the guide hole 33, and when the roller strip 17 squeezes the dividing strip 14, it can remove the water in the cavity 31. Water is squeezed outward through the guide holes 33, and the direction of extrusion is toward the surface of the conveyor belt 11 previously rolled by the rollers 17, impacting the compacted mud and sand, further dispersing the mud and sand. In conjunction with the bristles 23, mud and sand can be removed from multiple directions and angles. When the rollers 17 no longer squeeze the separator 14, the external water re-enters the cavity 31. The provision of guide blades 34 can limit the direction of the sprayed water flow, further directing the water flow toward the surface of the conveyor belt 11, thereby increasing the impact force.
