Description

Technical Field

[0001] The invention relates to the technical field of groundwater monitoring equipment, and in particular to a groundwater level monitoring instrument. Background Art

[0002] Groundwater monitoring includes water level monitoring, water quality monitoring, and water quantity monitoring. Water level monitoring usually involves installing water level sensors and other equipment to monitor groundwater level changes in real time and understand the dynamics of groundwater reserves. Water quality monitoring usually involves monitoring common inorganic ions, organic matter, and microorganisms in groundwater. It usually requires the use of sampling equipment to extract groundwater and send it to a testing laboratory for chemical analysis. Water quantity monitoring usually involves monitoring groundwater reserves and pressure changes to understand groundwater flow rates as well as runoff and discharge.

[0003] In the prior art, different monitoring equipment is used for different groundwater monitoring activities. For example, when monitoring the water level, a person manually holds the water level monitoring equipment near the groundwater pipe and puts a flexible ruler with scale lines into the groundwater pipe. When the lower end of the flexible ruler touches the groundwater surface, the sensor is triggered. At this time, the water level height can be read by observing the scale of the flexible ruler at the groundwater pipe mouth. However, this equipment needs to be operated manually every time during use. Manual operation requires continuous laying of lines, which is time-consuming and labor-intensive, and is not conducive to real-time monitoring and observation of the groundwater level. In addition, because the ground water level is too high, it may cause ground collapse, landslides and other address disasters. Manual operation is not conducive to real-time grasp of the warning height of the groundwater level. In addition, the manual method of measuring the groundwater level with a flexible ruler cannot monitor the flow rate of the groundwater, and the function is relatively simple.

[0004] In order to solve the above problems, a device is proposed which can monitor the groundwater level in real time and also can intuitively reflect the warning water level in real time. The device can monitor the groundwater flow rate and take samples of groundwater while measuring the groundwater level. Summary of the invention

[0005] In view of the above problems, the present invention provides a groundwater level monitoring instrument, which solves the problem that traditional water level testing instruments and equipment need to be manually operated every time during use. Manual operation requires continuous manual laying of lines, which is time-consuming and labor-intensive, and is not conducive to real-time monitoring and observation of the groundwater level. In addition, since an excessively high groundwater level may cause ground collapse, landslides and other address disasters, manual operation is not conducive to real-time grasp of the warning height of the groundwater level.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] refer to Figures 1 to 11 , a groundwater level monitoring instrument, comprising a ground to be installed 1, a groundwater pipe 2, an upper mounting plate 18, an expansion mounting plate 1801, a vertical mounting plate 5, a horizontal mounting plate 4, a hollow measuring rod 11, a floating plate 9, a collection tank 7, a top cover 20, an upper baffle 15, a lower baffle 24, an arc-shaped slide plate 6, a warning water level early warning mechanism, a water level monitoring mechanism, a sampling mechanism, a flow rate monitoring mechanism, and a fixing mechanism; An underground water pipe 2 is installed through the ground 1 to be installed. The upper end of the underground water pipe 2 is installed above the ground 1 to be installed, and the lower end of the underground water pipe 2 is installed below the ground 1 to be installed. The underground water pipe 2 is a conventional monitoring underground water pipe. The traditional monitoring method is to insert a tape measure into the underground water pipe 2 for monitoring. This device abandons the time-consuming and labor-intensive shortcomings of the traditional monitoring method and achieves the effect of real-time monitoring through the following structure; An upper mounting plate 18 is detachably mounted on the upper end of the underground water pipe 2, and expansion mounting plates 1801 are respectively mounted on the left and right side walls of the upper mounting plate 18, and vertical mounting plates 5 are respectively vertically mounted on the upper parts of the outer ends of the two expansion mounting plates 1801, and the two expansion mounting plates 1801 are respectively used to mount the vertical mounting plates 5, and a plurality of second scale lines are engraved on the side walls of the vertical mounting plates 5, which facilitates the staff to conduct real-time survey of the water level height of the warning water level in cooperation with the warning water level early warning mechanism described later; The same horizontal mounting plate 4 is fixedly mounted between the upper ends of the two vertical mounting plates 5. The cooperation between the horizontal mounting plate 4 and the hollow measuring rod 11 described later can monitor the water level change of the normal water level in real time; An upper baffle plate 15 is movably installed between the upper mounting plate 18 and the horizontal mounting plate 4. A hollow measuring rod 11 is slidably installed in the upper baffle plate 15. The hollow measuring rod 11 and the horizontal mounting plate 4 are detachably slidably installed. Since the hollow measuring rod 11 is hollow inside, it has buoyancy and can rise or fall synchronously with the rise or fall of the water level in cooperation with the floating plate 9 described later. The hollow measuring rod 11 is driven to slide by the water level monitoring mechanism; The two vertical mounting plates 5 are both equipped with the same warning water level early warning mechanism, which is driven to work by the water level monitoring mechanism; The front and rear side walls of the upper mounting plate 18 are both provided with fixing mechanisms, which are used to fix the device on the ground 1 to be installed and the underground water pipe 2; The upper mounting plate 18 is provided with two arc-shaped grooves 1804, in which arc-shaped slide plates 6 are respectively installed and slidably penetrated. The upper ends of the two arc-shaped slide plates 6 respectively slide through the arc-shaped slide plates 6 cooperating therewith and are fixedly connected to the lower end of the upper baffle plate 15. The two arc-shaped slide plates 6 can slide up and down along the two arc-shaped grooves 1804, respectively. The cooperation between the arc-shaped grooves 1804 and the arc-shaped slide plates 6 can also limit the sliding tracks of the two arc-shaped slide plates 6, and ensure that they will not deviate and fall off during the sliding process. The same lower baffle plate 24 is fixedly installed between the lower ends of the two arc-shaped slide plates 6. The lower baffle plate 24 is movably installed in the underground water pipe 2 located below the ground 1 to be installed. The lower baffle plate 24 and the upper baffle plate 15 are fixedly installed between the two arc-shaped slide plates 6. With the contact of the floating plate 9 described later, the lower baffle plate 24 will drive the two arc-shaped slide plates 6 and the upper baffle plate 15 to be lifted up at the same time. A collection tank 7 is installed at the upper end of the lower baffle 24. The collection tank 7 is installed between the two arc-shaped slides 6. The collection tank 7 is used to collect groundwater that needs to be sampled, so that the staff can obtain sample data of water quality in addition to water level information, thereby achieving the effect of enriching experimental data. The upper end of the collection tank 7 is detachably provided with a top cover 20, and the hollow measuring cylinder 11 is respectively provided with a sealing and sliding connection with the top cover 20 and the lower baffle 24. The top cover 20 is used to seal the top end of the collection tank 7, and its existence will not hinder the movement of the hollow measuring cylinder 11; A sampling mechanism is installed in the collection tank 7, and the sampling mechanism will extract water quality simultaneously with the floating plate 9 described later, so as to facilitate the monitoring of water quality described later; A floating plate 9 is movably installed below the lower baffle plate 24, and a lower end of the hollow measuring cylinder 11 is fixedly arranged between the upper end of the floating plate 9, and the upper end of the floating plate 9 is in detachable contact with the lower end of the lower baffle plate 24; The floating plate 9 works by floating and driving the sampling mechanism; A flow rate monitoring mechanism is installed at the lower end of the floating plate 9. The flow rate monitoring mechanism can provide real-time feedback on the flow rate information of groundwater, making it convenient for staff to grasp the flow rate information of groundwater. When the flow rate is too fast, geological disasters such as ground collapse will occur, making it convenient for personnel to obtain information in advance and take preventive measures.

[0020] The water level monitoring mechanism comprises a first scale line and a first circular hole; A plurality of first scale lines are mounted on the hollow measuring rod 11; A first circular hole is installed at the middle end of the horizontal mounting plate 4, and a hollow measuring rod 11 is slidably arranged to penetrate the first circular hole; Several first scale lines are in detachable contact with the first circular hole, and the hollow measuring rod 11 drives the warning water level warning mechanism to work by sliding. When the floating plate 9 contacts the groundwater, it will float on the surface of the groundwater and change with the change of the groundwater level. The hollow measuring rod 11 fixedly connected to the floating plate 9 will also move with the movement of the floating plate 9. During the floating process, the hollow measuring rod 11 will pass through the first circular hole and feed back several first scale lines thereon on the side wall of the first circular hole in real time. The staff can grasp the water level changes in real time by observing the part where the first scale lines overlap with the first circular hole.

[0021] The warning water level early warning mechanism comprises a rectangular slider 17 and a first connecting rod 16; The two vertical mounting plates 5 are respectively provided with first rectangular through grooves 501, and rectangular sliding blocks 17 are respectively slidably installed in the two first rectangular through grooves 501; The first ends of the connecting rods 16 are respectively installed on both sides of the upper baffle 15 near the inner sides of the two rectangular slide blocks 17; The second ends of the two first connecting rods 16 are respectively fixedly connected to the inner walls of the rectangular sliding blocks 17 adjacent thereto; The two first connecting rods 16 are movably installed above the expansion mounting plate 1801 close to them. When the groundwater level rises to the warning water level, the floating plate 9 will rise simultaneously with the water level and gradually contact the lower baffle plate 24. The lower baffle plate 24 will rise synchronously with the floating plate 9 at this time, and drive the two arc-shaped slide plates 6 fixed thereto to rise synchronously during the rising process. The two arc-shaped slide plates 6 respectively drive the upper baffle plate 15 fixed thereto to start rising during the rising process. The upper baffle plate 15 respectively drives the first connecting rods 16 on both sides to start rising during the rising process. The two first connecting rods 16 respectively drive the rectangular sliders 17 fixed thereto to start rising along the first rectangular through grooves 501 on both sides during the rising process. Since the groundwater level is already in the warning water level state at this time, when the two rectangular sliders 17 are active, it has been intuitively reflected that the groundwater level is already in the warning state. With the continuous activity of the two rectangular sliders 17, the specific water level data of the warning water level will be reflected on the second scale line on the first rectangular through groove 501, so that the staff can observe the specific water level data of the groundwater warning water level conveniently.

[0022] The sampling mechanism comprises a connecting rod 8, a water suction pipe 13, a piston disc 21, an L-shaped connecting rod 22, a first arc-shaped slider 14, a second connecting rod, a second arc-shaped slider 1401, and a spring telescopic rod 23; The side walls of the two arc-shaped slide plates 6 are respectively provided with second rectangular through grooves 601, and the first arc-shaped slide blocks 14 cooperating therewith are respectively slidably installed in the two second rectangular through grooves 601; First connecting shafts are fixedly mounted on the outer walls of the two first arc-shaped sliding blocks 14 respectively; The first ends of the connecting rods 8 are fixedly mounted on the outer walls of the two first connecting shafts; The second connecting shafts are fixedly mounted on both side walls of the floating plate 9; The second ends of the two connecting rods 8 are respectively fixedly sleeved on the outer wall of the second connecting shaft close thereto; Both connecting rods 8 are movably installed in an underground water pipe 2 located below the ground 1 to be installed; Third rectangular through grooves 701 are respectively provided on the two side walls of the collection tank 7 near the two second rectangular through grooves 601; The second arc-shaped sliders 1401 are installed in the two third rectangular through grooves 701 in a sliding and sealing manner. The two second arc-shaped sliders 1401 are respectively connected to the third rectangular through grooves 701 matched therewith through flexible water retaining plates to prevent the collected liquid from flowing out of the third rectangular through grooves 701 on both sides. The outer walls of the two second arc-shaped sliding blocks 1401 are respectively fixedly connected to the inner walls of the first arc-shaped sliding blocks 14 adjacent thereto via second connecting rods; The inner walls of the two second arc-shaped sliding blocks 1401 are respectively fixed with the horizontal bars of the L-shaped connecting rod 22, and the ends of the vertical bars of the two L-shaped connecting rods 22 are fixed with the same piston disc 21; The piston disc 21 is sealingly and slidably installed in the collection tank 7; A sliding seal is provided between the hollow measuring cylinder 11 and the piston disc 21; The lower end of the bottom wall of the collection tank 7 is connected to and installed with two water suction pipes 13, and the lower baffle plate 24 is respectively provided with two second circular holes that cooperate with the water suction pipes 13; Two water suction pipes 13 are respectively arranged to penetrate between the second circular holes matched therewith; The hollow measuring cylinder 11 is respectively installed between the two water suction pipes 13; The upper end of the upper baffle 15 is connected to the horizontal mounting plate 4 via two spring telescopic rods 23; The hollow measuring cylinder 11 is movably installed between the two spring telescopic rods 23. As the groundwater level gradually rises, the floating plate 9 starts to drive the connecting rods 8 on both sides to rise synchronously, and in the process of rising, the first arc-shaped sliders 14 on both sides are driven to start sliding upward. At this time, the spring telescopic rod 23 always provides a downward pressure for the upper baffle 15, and its function is to fix the collection tank 7 in a position. At this time, the reset elastic force provided by the spring telescopic rod 23 to the upper baffle 15 is greater than the buoyancy of the floating plate 9. As the two first arc-shaped sliders 14 slide upward, they are separated. The second curved slider 1401 drives the piston disk 21 fixedly connected to it by the L-shaped connecting rod 22 to start sliding upward along the collection tank 7. At this time, the collection tank 7 is relatively immobile under the compression of the spring telescopic rod 23. Therefore, the piston disk 21 can smoothly pump water during the upward sliding process. When the floating plate 9 contacts the lower baffle plate 24, the lower baffle plate 24 will float up with the collection tank 7. When a water quality sample is needed, the equipment can be taken out and the collection tank 7 can be taken out alone.

[0023] The flow rate monitoring mechanism comprises a circular mounting plate 10, a monitoring fan blade 12, and an electrical box 3; Circular mounting plates 10 are vertically mounted on both sides of the lower end of the floating plate 9; Two water suction pipes 13 are respectively slidably arranged between the floating plates 9, and the two water suction pipes 13 located below the floating plates 9 are both installed on the outside of the circular mounting plates 10 close thereto; A rotating shaft is rotatably mounted between the two circular mounting plates 10, and a plurality of monitoring fan blades 12 are fixedly mounted on the rotating shaft; A speed sensor is installed in the rotating shaft, and an electric box 3 is installed on the upper end of the ground 1 to be installed. The speed sensor is electrically connected to the electric box 3 through a number of wires, and an alarm for alarming is installed in the electric box 3; Several wires are installed in the cavity inside the hollow measuring cylinder 11. Since the floating plate 9 is always above the water level of the groundwater, the two circular mounting plates 10 at the lower end of the floating plate 9 are always below the water surface. Several monitoring blades 12 located between the two circular mounting plates 10 are also below the water surface. The water flow will contact the monitoring blades 12 and drive the monitoring blades 12 to start rotating. The monitoring blades 12 will transmit data to the electrical box 3 on the ground through the speed sensor through rotation. The electrical box 3 will monitor the specific data of the speed in real time, and can set the alarm range by setting the speed threshold to increase safety.

[0024] The fixing mechanism comprises a rectangular block 1802 and an L-shaped leg 19; Rectangular blocks 1802 are fixedly mounted on the front and rear side walls of the upper mounting plate 18, and rectangular slide grooves 1803 are respectively provided at the lower ends of the two rectangular blocks 1802; The vertical plates with L-shaped legs 19 are slidably installed in the two rectangular slide grooves 1803; The horizontal plates of the two L-shaped legs 19 can be detachably installed on the upper end of the ground 1 to be installed. Since the lengths of the upper ends of some underground water pipes exposed from the ground vary, the L-shaped legs 19 are extended to match the exposed length of the underground water pipes, and then fixedly connected to the rectangular block 1802 close to them by screws and bolts. Then, the horizontal plates of the L-shaped legs 19 are also fixed to the ground by screws to fix the equipment on the upper end of the underground water pipe 2 at the monitoring point.

[0025] Implementation method of the present invention: Extend the L-shaped legs 19 of the device to a suitable length and fix the device to the upper end of the underground water pipe 2 at the monitoring point, ensure that the two arc-shaped slide plates 6 are inside the underground water pipe 2, and ensure that the floating plate 9 contacts the surface of the groundwater; As the underground water level rises, the floating plate 9 will begin to rise synchronously with the water level, and in the process of rising, it will drive the hollow measuring rod 11 fixedly installed therewith to begin to rise; The hollow measuring rod 11 will pass through the first circular hole during the rising process. At this time, the first scale line passes through the first circular hole. The staff can grasp the groundwater level in real time by observing the first scale line. As the floating plate 9 rises, the piston disc 21 in the collection tank 7 will also pump water synchronously to temporarily store the water quality sample in the collection tank 7. When the groundwater level gradually reaches the warning water level, the floating plate 9 gradually contacts the lower baffle plate 24 and drives the lower baffle plate 24 to gradually lift up. The lower baffle plate 24 will then carry the collection tank 7 to lift up, and in the process of lifting up, the upper baffle plate 15 will be driven to lift up through the two arc-shaped slide plates 6. When the upper baffle plate 15 starts to move, it means that the groundwater level has reached the warning water level. When it is further necessary to know the specific water level data of the warning water level, it can be intuitively seen by observing the sliding of the two rectangular sliders 17 lifted up together with the upper baffle 15 in the two first rectangular through grooves 501, and the staff can know the specific value of the warning water level through the second scale line on the first rectangular through groove 501; Since the floating plate 9 is always above the surface of the groundwater, the two circular mounting plates 10 drive the monitoring blades 12 to always be below the water surface. The water flows through several monitoring blades 12, driving them to start rotating and transmitting the rotation data generated during the rotation to the electrical box on the ground through the speed sensor. The staff can trigger the alarm by adjusting the speed threshold on the electrical box, which is not only convenient for monitoring the flow rate of groundwater, but also convenient for early warning of disasters.

[0026] When a water sample is needed, the device is dismantled and the internal collection tank 7 is taken out.

[0027] The present invention avoids the traditional manual hand-held measuring ruler gradually laying out the line method, which can only monitor the groundwater level in a fixed time period. It can monitor the groundwater level in real time and have a certain monitoring effect on the warning water level. At the same time, it can also monitor the water flow velocity of the groundwater level to a certain extent while monitoring the water level and the warning water level.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
