Description

Technical Field

[0001] This invention belongs to the field of water level monitoring technology, specifically relating to a groundwater level monitoring instrument with Beidou communication and positioning technology. Background Technology

[0002] Groundwater level monitoring refers to the elevation of the water surface in underground aquifers. Based on the drilling observation time, it can be divided into initial water level, stable water level, water level during the wet season, water level during the dry season, and water level before freezing. Groundwater can be classified in different ways according to different standards. Based on the hydraulic characteristics and burial conditions of groundwater, it is divided into vadose zone water, unconfined groundwater, and confined groundwater. Unconfined groundwater is buried below the surface and above the first impermeable layer. It has a free surface and is directly replenished by atmospheric precipitation. Its water level, water temperature, and water quality change accordingly with changes in local meteorological factors.

[0003] When using a groundwater level monitoring instrument, it is not possible to quickly fix the instrument in place, nor can it be protected. Furthermore, it is not convenient to protect the water level sensor during monitoring, which can easily lead to damage when the sensor is placed inside the monitoring well. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a groundwater level monitoring instrument with Beidou communication and positioning technology, which has the advantages of being able to quickly fix the groundwater level monitoring instrument, and provide protection for the groundwater level monitoring instrument, as well as the water level sensor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a groundwater level monitoring instrument with Beidou communication and positioning technology, comprising a base and a groundwater level monitoring instrument, wherein the top center of the base overlaps with the bottom of the groundwater level monitoring instrument, a connecting line is movably connected to the back of the groundwater level monitoring instrument, and a water level sensor is fixedly connected to the other end of the connecting line, a quick fixing mechanism is provided on the top of the base, and a protective mechanism is provided on the bottom of the base and the outer wall of the water level sensor.

[0006] The quick-fixing mechanism includes a quick-fixing unit and a guiding unit, and the protective mechanism includes a winding unit and a protective unit.

[0007] The quick-fixing unit includes a hollow block fixedly connected to the top edge of the base. A fixing cylinder is embedded in the outer wall of the hollow block. A bearing is fixedly installed on the inner wall of the fixing cylinder and inside the hollow block. A rotating rod is fixedly connected to the inner wall of the bearing. A U-shaped block is fixedly connected to one end of the rotating rod and inside the hollow block. A handle is fixedly connected to the other end of the rotating rod. Two pressing blocks are fixedly connected to the outer wall of the rotating rod.

[0008] Preferably, a fixed ring is fixedly connected to the inner wall of the fixed cylinder, a spring is fixedly connected to the side of the fixed ring, a movable push block is fixedly connected to the other end of the spring, a movable rod is fixedly connected to the outer wall of the movable push block, the other end of the movable rod passes through the outer wall of the fixed ring, and the inner wall of the fixed ring is slidably connected to the outer wall of the rotating rod.

[0009] Through the above technical solution, the rotating rod drives the extrusion block to rotate synchronously, thereby pushing the movable push block. Then, the movable push block is automatically reset by the spring, which facilitates the limiting of the rotating rod.

[0010] Preferably, a fixed cover is fixedly connected to the end of the fixed cylinder away from the hollow block, and a limit ring is rotatably connected to the inner wall of the fixed cover. The inner wall of the limit ring is fixedly connected to the outer wall of the rotating rod.

[0011] With the above technical solution, the limiting ring and the fixed cover can rotate, which facilitates the rotation of the rotating rod.

[0012] Preferably, the quick fixing unit further includes a protective cover plate positioned directly above the groundwater level monitor. A sponge block is fixedly connected to the bottom center of the protective cover plate, and the bottom of the sponge block overlaps with the top of the groundwater level monitor. An insert plate is fixedly connected to the bottom edge of the protective cover plate, and a limiting plate is fixedly connected to the bottom of the insert plate. The outer wall of the insert plate is movably connected to the inner wall of the U-shaped block.

[0013] Through the above technical solution, the U-shaped block can limit the insertion plate and the limiting plate, thereby enabling the rapid installation of the protective cover plate, and the sponge block can buffer the protective cover plate and the groundwater level monitoring instrument.

[0014] Preferably, the guiding unit includes a fixed chamber fixedly connected to the side of the hollow block, a guide plate rotatably connected to the inner wall of the fixed chamber, an arc-shaped spring piece fixedly connected to the side of the guide plate, the other end of the arc-shaped spring piece being fixedly connected to the inner wall of the fixed chamber, a groove being formed on the outer wall of the guide plate, and a guide wheel rotatably connected to the inner wall of the groove.

[0015] With the above technical solution, the groundwater level monitor comes into contact with the guide wheel, making it easy to place on the base. At the same time, the arc-shaped spring can push the guide plate, thereby limiting the groundwater level monitor by the guide wheel on the guide plate.

[0016] Preferably, the winding unit includes a storage compartment fixedly installed at the bottom of the base. A fixing rod is fixedly connected to the inner wall of the storage compartment, and a winding drum is slidably connected to the outer wall of the fixing rod. The outer wall of the winding drum is slidably connected to the inner wall of the storage compartment. A handle is fixedly connected to one end of the winding drum, and a limit block is fixedly connected to the other end of the winding drum. An elastic rope is fixedly connected to the other end of the winding drum and to the side of the limit block. The other end of the elastic rope is fixedly connected to the inner wall of the storage compartment.

[0017] Through the above technical solution, the handle can pull the take-up drum outward, which makes it easier to wind the connecting cable onto the take-up drum. At the same time, the elastic rope can make the take-up drum automatically reset, providing protection for the connecting cable and preventing damage to the connecting cable.

[0018] Preferably, the protective unit includes a connecting ring fixedly installed on the outer wall of the water level sensor, an outer protective cylinder movably connected to the bottom of the connecting ring, a buffer seat fixedly connected to the bottom of the outer protective cylinder, a positioning ring fixedly connected to the center of the top of the buffer seat, and the inner wall of the positioning ring being adapted to the outer wall of the water level sensor.

[0019] Through the above technical solutions, the buffer seat and outer protective cylinder can provide protection for the water level sensor when it is placed in the monitoring well, thus preventing damage to the water level sensor.

[0020] Preferably, the outer wall of the outer protective cylinder has an opening, the inner wall of the opening is fixedly installed with a filter screen, the inner wall of the outer protective cylinder is fixedly connected with a buffer strip, and the outer wall of the buffer strip is in contact with the outer wall of the water level sensor.

[0021] Through the above technical solution, the filter screen can facilitate water to enter the interior of the outer protective cylinder, thereby facilitating the water level sensor to monitor the water level.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The rotating rod and the extrusion block rotate synchronously, which facilitates the extrusion block to push the movable push block. The spring causes the movable push block to automatically reset, thereby limiting the rotation of the rotating rod. This allows the U-shaped block to fix the inserted plate, and the protective cover plate to limit the groundwater level monitor. It also provides protection for the surface of the groundwater level monitor to prevent damage. The groundwater level monitor contacts the guide wheel, and the arc-shaped spring pushes the guide plate outward, causing the guide wheel on the guide plate to limit the groundwater level monitor, further improving the stability of the groundwater level monitor and facilitating quick fixation of the groundwater level monitor.

[0024] 2. The buffer seat and positioning ring facilitate connection with the water level sensor, while the connecting ring can connect with the outer protective cylinder, so that the outer protective cylinder provides protection for the water level sensor when it is placed in the monitoring well, avoiding damage to the water level sensor. The filter screen facilitates water to enter the interior of the outer protective cylinder, so that the water level sensor can monitor the water level.

[0025] 3. Pull the handle to move the winding drum outward, making it easier to wind the connecting cable onto the drum and wind it up, so that the connecting cable is neatly placed. At the same time, the elastic rope can automatically reset the winding drum, so that the storage compartment can protect the winding drum and prevent damage when the connecting cable is exposed.

[0043] In this embodiment, the groundwater level monitor 2 is placed on the base 1 by contacting the guide wheel 584. At the same time, the arc-shaped spring piece 582 pushes the guide plate 581, so that the guide wheel 584 on the guide plate 581 limits the groundwater level monitor 2 and further fixes the groundwater level monitor 2.

[0044] Specifically, the protective unit includes a connecting ring 67 fixedly installed on the outer wall of the water level sensor 4.

The outer protective cylinder 671 provides protection when the water level sensor 4 is placed in the monitoring well, preventing damage to the water level sensor 4. The filter screen 674 allows water to easily enter the interior of the outer protective cylinder 671, thereby facilitating the water level sensor 4 to monitor the water level, while also preventing excessive impurities from adhering to the surface of the water level sensor 4.

[0046] Specifically, the winding unit includes a storage compartment 61 fixedly installed at the bottom of the base 1.

Then, insert the insert plate 572 on the protective cover 57 into the hollow block 51. Manually rotate the handle 542, causing the rotating rod 54 and the pressing block 543 to rotate synchronously. The pressing block 543 pushes the movable push block 552, while the spring 551 automatically resets the movable push block 552, thus limiting the rotation of the rotating rod 54. The U-shaped block 541 fixes the inserted plate 572. The protective cover 57 limits and quickly fixes the groundwater level monitor 2, while also protecting the surface of the groundwater level monitor 2. The water level sensor 4 is placed inside the outer protective cylinder 671, and the connecting ring 67 is connected to the outer protective cylinder 671.
