[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.
[0026] A landfill liquid level detection device, such as Figure 1-Figure 5As shown, it includes a landfill 1, a drilling tube 2, a floating inner tube 3 and a liquid level probe 4. The drilling tube 2 is detachably installed in the landfill 1, the drilling tube 2 is vertically placed in the landfill 1, the floating inner tube 3 is movably installed in the drilling tube 2, the liquid level probe 4 passes through the floating inner tube 3 along the axis and is clamped with a floating support plate 5, the liquid level probe 4 is connected to the detector through a wire 9, scales are provided on the drilling tube 2 and the floating inner tube 3, the drilling tube 2 is sleeved on the floating inner tube 3, the floating inner tube 3 is sleeved on the liquid level probe 4 connected to the wire 9, the drilling tube 2 is vertically placed with the landfill 1, which can effectively improve the measurement accuracy, when the drilling tube 2 is drilled, it can be clearly judged whether the whole reaches the bottom through the scale on it, and the movable installation of the floating inner tube 3 allows It moves up and down with the fluctuation of the liquid level and can reflect the changes in the liquid level inside the landfill 1 in real time. The liquid level probe 4 is clamped to the floating support plate 5 to ensure its stability and safety during the measurement process, and to ensure that the liquid level probe 4 does not swing back and forth, thus avoiding measurement errors caused by the probe falling off or being damaged. By real-time monitoring of the changes in the liquid level inside the landfill 1, the safety of the landfill 1 is improved. The scale on the floating inner cylinder 3 cooperates with the liquid level probe 4 to intuitively display the changes in the liquid level, so that operators and inspectors can quickly understand the liquid level conditions inside the landfill 1. The floating inner cylinder 3 is movably installed in the drill cylinder 2. Its design principle is similar to that of a buoy, and it can float up and down with the rise or fall of the leachate level.
[0027] The drilling cylinder 2 includes a supporting outer cylinder 21, a filter screen cylinder 22 and a flat-angle drill bit 23. The flat-angle drill bit 23 is fixedly connected to the supporting outer cylinder 21 through the filter screen cylinder 22. A limit platform is provided at one end of the supporting outer cylinder 21 away from the flat-angle drill bit 23. A handle 8 is provided on the limit platform. The top surface of the limit platform is threadedly connected to the cover 7. A scale is provided on the outer surface of the supporting outer cylinder 21. The flat-angle drill bit 23 will not break through the gravel layer when drilling to the bottom, thereby avoiding unnecessary damage to the anti-seepage layer. The scale on the supporting outer cylinder 21 provides accurate depth measurement, so that the operator can accurately grasp the position of the drilling cylinder 2 in the soil or rock, thereby ensuring the accuracy of the measurement. The supporting outer cylinder 21 is made of hard plastic, and the filter screen cylinder 22 between the flat-angle drill bit 23 and the supporting outer cylinder 21 effectively isolates solid waste and facilitates the entry of leachate, thereby improving the accuracy of measurement. The cover 7 provides a basic scale reference for the floating inner cylinder 3. When the floating inner cylinder 3 floats up and down in the drilling cylinder 2, the operator can quickly and accurately read the current position of the floating inner cylinder 3, thereby obtaining the accurate liquid level information of the liquid in the landfill 1. This scale reference improves the measurement accuracy and efficiency, allowing the operator to complete the liquid level measurement work more quickly and accurately, and force holes are opened on both sides of the cover 7 to facilitate unscrewing the cover 7 and taking out the buoyant inner cylinder.
[0028] The floating inner cylinder 3 includes a guide cylinder 31 and a floating ball 32. One end of the guide cylinder 31 is detachably connected to the floating ball 32. The guide cylinder 31 axially penetrates the cover 7 and the supporting outer cylinder 21. The floating ball 32 is located above the flat-angle drill bit 23. The guide cylinder 31 and the floating ball 32 are both provided with through holes along the axis. The outer surface of the floating inner cylinder 3 is provided with scales. The floating support plate 5 is clamped with the floating ball 32. The outer surface of the guide cylinder 31 away from the floating ball 32 is provided with a limit plate 6. The limit plate 6 is located above the cover 7. The guide cylinder 31 is preferably made of light The floating ball 32 is made of high-quality plastic to reduce the pressure on the floating ball 32, and cooperates with the sealing cover 7 to guide the floating ball 32 to make regular up and down movements. The limit plate 6 effectively limits the floating inner cylinder 3 to the lowest position in the drilling cylinder 2 to avoid collision with the flat-angle drill bit 23, thereby extending the service life of the device. The guide cylinder 31 and the floating ball 32 are threadedly connected for easy disassembly and maintenance. The liquid level probe 4 is fitted and connected with the floating support plate 5, and the floating support plate 5 is fitted and connected with the floating ball 32, which can effectively prevent the leachate from entering the through hole of the floating ball 32 and avoid inaccurate measurement.
[0029] The parts and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.
[0030] Working principle: The staff member holds the handle 8 and rotates it to drive the flat-angle drill bit 23 to drill downward. According to the scale on the outer surface of the supporting outer cylinder 21, the staff member determines that the staff member has reached the bottom of the landfill 1. At this time, the leachate begins to enter the supporting outer cylinder 21 from the filter cylinder 22. Further, the floating inner cylinder 3 in the supporting outer cylinder 21 begins to float under force. Due to the limit of the cover 7, the guide cylinder 31 can only guide the floating ball 32 to move up and down. At this time, the staff member can judge whether the leachate has accumulated too much according to the scale of the guide cylinder 31 floating up and protruding from the cover 7, and can also judge through the information sent back by the liquid level probe 4, providing double protection;
[0031] When maintenance is needed, it is only necessary to unscrew the cover 7. At this time, the cover 7 cannot be completely removed due to the upper limit plate 6 on the guide cylinder 31. The staff slowly pulls out the floating inner cylinder 3, further disassembles the floating support plate 5 and the floating ball 32, and performs maintenance and repair on the liquid level probe 4.
