Description

Technical Field

[0001] The utility model belongs to the technical field of measuring devices, in particular to a groundwater level measuring device. Background Art

[0002] The groundwater level measuring device is a device used to monitor changes in groundwater levels and is widely used in water resource management, environmental monitoring, and engineering design. Common measuring devices include float-type water level gauges, pressure sensors, and resistive water level sensors. These devices are usually installed in groundwater observation wells and can provide real-time groundwater level data to help researchers and managers assess water resource conditions and formulate reasonable water resource management strategies. Existing groundwater level measuring devices cannot meet the needs of measuring groundwater levels in different locations because the installation relationship between the winding wheel and the bracket is fixed. The conventional solution is to replace the winding wheel with different models to meet the needs of different locations. However, since the installation relationship between the winding wheel and the bracket is fixed, the entire device needs to be replaced. The disadvantage of this method is that several sets of measuring devices need to be prepared in advance, which is time-consuming and labor-intensive. Therefore, a new structure is proposed to solve the above problem. Utility Model Content

[0005] A set of winding wheels is provided between the driven roller 1 and the driven roller 2, and a set of adjustment rods are respectively provided at the front and rear positions on the right side of the top of the base. A plurality of positioning holes are provided on the front and back of each set of adjustment rods, and a sliding adjustment group is provided on the outer side of each set of adjustment rods;

[0006] The sliding adjustment group consists of a sliding sleeve, a clamping ring and a handle. A measuring line is provided on the outside of the winding wheel, a positioning cone is provided on the right side of the measuring line, a sensor is installed at the bottom of the positioning cone, and the positioning cone is a conical structure.

[0007] As a preferred embodiment, a set of stabilizing legs are respectively provided at the front and rear positions on the left side of the base, a set of rotating shafts are provided through the center of the front and back of the winding wheel, and the radius of the winding wheel is 50 cm;

[0008] The front side of the rotating shaft is placed inside the front clamping ring, and the rear side of the rotating shaft is placed inside the rear clamping ring. A servo reduction motor is provided on the front side of the rotating shaft, and the front side of the rotating shaft is connected to the output end of the servo reduction motor through a coupling.

[0009] As a preferred embodiment, the bottom of the clamping ring is welded and fixed to the top of the sliding sleeve, the inner side of the sliding sleeve is movably connected to the outer side of the adjustment rod, and the bottom of the sliding sleeve is welded and fixed to the top of the handle.

[0010] As a preferred embodiment, a fixing mechanism 1 is provided at the lower right side of the adjusting rod, the bottom of the fixing mechanism 1 is hinged to the upper right side of the base through a hinge column, and a positioning pin is provided on the outer side of the adjusting rod.

[0011] As a preferred embodiment, the sliding sleeve is provided with fixing holes on the front and back sides, the radius length of the fixing hole is greater than the radius length of the positioning pin, the radius length of the fixing hole is equal to the radius length of the positioning hole, and the fixing hole and the positioning hole are in the same horizontal plane.

[0012] As a preferred embodiment, the positioning cone is made of stainless steel, the height of the positioning cone is 15 cm, the lower right side of the measuring line is placed on the inner side of the top of the auxiliary pulley, the auxiliary pulley is connected and fixed to the ground through a second fixing mechanism, a ground hole is opened on the right side of the auxiliary pulley, and an alarm is provided on the right side of the ground hole. In actual use, pick up the second set of winding wheels that meet the measurement requirements, insert the front side of the rotating shaft into the front clamping ring, insert the rear side of the rotating shaft into the rear clamping ring, then hold the winding wheel and put it down gently, at this time the rotating shaft drives the two sets of clamping rings to move downward, At the same time, the sliding sleeve is driven by the clamping ring to move along the adjusting rod, and the left side of the bottom of the winding wheel contacts the right side of the top of the two sets of driven rollers, and the right side of the bottom of the winding wheel contacts the left side of the top of the two sets of driven rollers, so that the winding wheel is placed. Then the sliding sleeve is fine-tuned to make the fixing hole and the corresponding positioning hole relative to each other, and the positioning pins are picked up and inserted into the fixing hole and the positioning hole respectively to complete the replacement of the winding wheel.

An information receiving mechanism, an information conversion mechanism, an alarm mechanism, and a power storage mechanism are provided within the alarm. The alarm is connected to a sensor via a wireless signal. In actual use, the servo reduction motor is activated to rotate clockwise. The rotation of the servo reduction motor drives the rotation of the rotating shaft, thereby driving the winding reel to rotate clockwise to pay out the line. As the winding reel rotates clockwise, friction causes the two sets of driven rollers 1 and 2 to rotate counterclockwise, thereby assisting the winding reel in rotating. Under the weight of the positioning cone, the measuring line follows the positioning cone downward within the ground hole. When the bottom of the positioning cone contacts the groundwater interface, the sensor collects the sensing signal and transmits it to the alarm. The alarm receives and converts the signal into a signal recognizable by the alarm mechanism, then sounds an alarm. The operator can then immediately stop paying out the line (the servo reduction motor, alarm, and sensor are all existing technologies, and their models can be selected as needed, so they will not be described in detail). The height of the groundwater level from the ground is then calculated based on the number of windings of the line paid out, the radius of the winding reel, and the height of the positioning cone. This device is simple and convenient to use.

[0014] After adopting the above technical solution, the beneficial effect of the utility model is: by setting the adjusting rod, sliding sleeve, clamping ring, handle, positioning hole and positioning pin, the front and rear sides of the rotating shaft can be placed inside the front and rear two sets of clamping rings respectively, and then the sliding sleeve is adjusted to move the sliding sleeve along the adjusting rod to make the winding wheel installed stably. At this time, the position of the fixing hole is relative to the position of the positioning hole. Pick up a set of positioning pins and insert the positioning pins into the fixing hole and the positioning hole respectively to complete the installation of the winding wheel. When it is necessary to measure the groundwater level at different locations, the first set of winding wheels can be removed first, and then replaced with the second set of winding wheels. Then, the sliding adjustment group can be adjusted according to the above steps to quickly complete the installation of the winding wheel to meet the measurement of groundwater at different locations.

[0024] See also Figures 1 to 4 A groundwater level measuring device includes a base 100, an adjusting rod 120, and a positioning cone 170. A set of driven rollers 140 are provided at the front and rear positions on the left side of the top of the base 100, and two sets of driven rollers 150 are provided on the right side of the two sets of driven rollers 140.

[0025] A winding wheel 160 is provided between the driven roller 140 and the driven roller 2 150. A set of adjustment rods 120 are provided at the front and rear positions of the top right side of the base 100. A plurality of positioning holes 200 are provided on the front and back of each set of adjustment rods 120. A sliding adjustment group 130 is provided on the outer side of each set of adjustment rods 120.

[0026] The sliding adjustment group 130 consists of a sliding sleeve, a clamping ring 230 and a handle 220. A measuring line is provided on the outside of the winding wheel 160, and a positioning cone 170 is provided on the right side of the measuring line. A sensor 240 is installed at the bottom of the positioning cone 170, and the positioning cone 170 is a conical structure.

[0027] A set of stabilizing legs 110 are provided at the front and rear positions on the left side of the base 100, and a set of rotating shafts are provided through the center of the front and back of the winding wheel 160. The radius of the winding wheel 160 is 50 cm.

[0028] The front side of the rotating shaft is placed inside the front clamping ring 230, and the rear side of the rotating shaft is placed inside the rear clamping ring 230. A servo reduction motor is provided on the front side of the rotating shaft, and the front side of the rotating shaft is connected to the output end of the servo reduction motor through a coupling.

[0029] The bottom of the clamping ring 230 is welded and fixed to the top of the sliding sleeve. The inner side of the sliding sleeve is movably connected to the outer side of the adjustment rod 120. The bottom of the sliding sleeve is welded and fixed to the top of the handle 220.

[0030] A fixing mechanism 1 is provided at the lower right side of the adjusting rod 120 , and the bottom of the fixing mechanism 1 is hinged to the upper right side of the base 100 through a hinge column. A positioning pin 210 is provided on the outer side of the adjusting rod 120 .

[0031] The sliding sleeve has fixing holes on both the front and back sides. The radius of the fixing holes is greater than the radius of the positioning pin 210 and is equal to the radius of the positioning hole 200. The fixing holes and the positioning hole 200 are in the same horizontal plane.

[0032] The positioning cone 170 is made of stainless steel, and the height of the positioning cone 170 is 15 cm. The lower right side of the measuring line is placed on the inner side of the top of the auxiliary pulley 190. The auxiliary pulley 190 is fixed to the ground through a second fixing mechanism. A ground hole is opened on the right side of the auxiliary pulley 190, and an alarm 180 is provided on the right side of the ground hole. In actual use, pick up the second set of winding wheels 160 that meet the measurement requirements, insert the front side of the rotating shaft into the front clamping ring 230, insert the rear side of the rotating shaft into the rear clamping ring 230, and then hold the winding wheel 160 and put it down gently. At this time, the rotating shaft drives the two sets of clamping rings 230 to move downward, and at the same time drives the sliding sleeve along the clamping ring 230. As the adjusting rod 120 moves, the left side of the bottom of the winding wheel 160 contacts the right side of the top of the two sets of driven rollers 140, and the right side of the bottom of the winding wheel 160 contacts the left side of the top of the two sets of driven rollers 2 150, thereby placing the winding wheel 160. Then, the sliding sleeve is fine-tuned to make the fixing hole and the corresponding positioning hole 200 relative to each other, and the positioning pin 210 is picked up and inserted into the fixing hole and the positioning hole 200 respectively, thereby completing the replacement of the winding wheel 160. The final effect is that different sizes of winding wheels 160 can be replaced on a set of bases 100 and stabilizing legs 110, so that the winding wheel 160 can be replaced at any time to meet the measurement of groundwater levels at different locations.

[0033] A bracket is provided under the alarm 180, and an information receiving mechanism, an information conversion mechanism, an alarm mechanism and a power storage mechanism are provided inside the alarm 180. The alarm 180 is connected to the sensor 240 via a wireless signal. In actual use, the servo reduction motor is started to rotate clockwise, and the rotation of the servo reduction motor drives the rotation of the shaft, thereby driving the winding wheel 160 to rotate clockwise to pay out the line. When the winding wheel 160 rotates clockwise, due to the friction force, the two sets of driven rollers 1 140 rotate counterclockwise, and the two sets of driven rollers 2 150 rotate counterclockwise, thereby assisting the rotation of the winding wheel 160, and measuring the line under the action of the gravity of the positioning cone 170. As the positioning cone 170 moves downward inside the ground hole, after the bottom of the positioning cone 170 touches the groundwater interface, the sensor 240 collects the sensing signal and transmits the signal to the alarm 180. The alarm 180 receives the signal and converts it into a signal that can be recognized by the alarm mechanism, and then starts to alarm. The staff can immediately stop paying out the line (the servo reduction motor, alarm 180 and sensor 240 are all existing technologies, and their models can be selected according to needs, and will not be repeated here). Then, the height of the groundwater level from the ground is calculated based on the number of turns of the paid-out line, the radius of the winding wheel 160 and the height of the positioning cone 170. It is simple and convenient to use.

[0034] Example 1: Please refer to Figure 1 、 Figure 2 and Figure 4In actual use, the auxiliary pulley 190 is installed on the left side of the ground hole in advance, and then the base 100 and the stabilizing leg 110 are installed on the left side of the auxiliary pulley 190. At this time, the winding wheel 160 is in the installed state by default, and the right side of the measuring line and the positioning cone 170 are placed along the ground hole so that the lower right side of the measuring line is inside the top of the auxiliary pulley 190. When the measuring line moves down, the auxiliary pulley 190 follows and rolls, thereby making the release of the measuring line more stable and ensuring that the measuring line and the positioning cone 170 do not contact the side of the ground hole. Then start the servo reduction motor to rotate clockwise. The rotation of the servo reduction motor drives the rotation of the shaft, thereby driving the winding wheel 160 to rotate clockwise to release the line. When the winding wheel 160 rotates clockwise, the two sets of driven rollers 140 rotate counterclockwise due to friction. The two sets of driven rollers 150 rotate counterclockwise, thereby assisting the winding wheel 160 to rotate. Under the action of the gravity of the positioning cone 170, the measuring line follows the positioning cone 170 and moves downward inside the ground hole. After the bottom of the positioning cone 170 contacts the groundwater interface, the sensor 240 collects the sensing signal and transmits the signal to the alarm 180. The alarm 180 receives the signal and converts it into a signal that can be recognized by the alarm mechanism, and then starts to alarm. The staff can immediately stop paying out the line at this time (the servo reduction motor, alarm 180 and sensor 240 are all existing technologies, and their models can be selected according to needs, and will not be repeated here). Then, the height of the groundwater level from the ground is calculated based on the number of turns of the paid-out line, the radius of the winding wheel 160 and the height of the positioning cone 170. It is simple and convenient to use.

[0035] Example 2: Please refer to Figures 1 to 3When it is necessary to measure groundwater at different locations, the first set of winding wheels 160 can be disassembled in advance, and then the base 100, the stabilizing legs 110 and the auxiliary pulley 190 can be disassembled and installed at another measuring point. According to the above steps, the base 100, the stabilizing legs 110 and the auxiliary pulley 190 are installed respectively. Then, pick up the second set of winding wheels 160 that meet the measurement requirements, insert the front side of the rotating shaft into the front clamping ring 230, insert the rear side of the rotating shaft into the rear clamping ring 230, and then hold the winding wheel 160 and put it down gently. At this time, the rotating shaft drives the two sets of clamping rings 230 to move downward, and at the same time drives the sliding sleeve through the clamping ring 230. The drum moves along the adjusting rod 120, and the left side of the bottom of the winding wheel 160 contacts the right side of the top of the two sets of driven rollers 140, and the right side of the bottom of the winding wheel 160 contacts the left side of the top of the two sets of driven rollers 150, so that the winding wheel 160 is placed. Then the sliding sleeve is fine-tuned to make the fixing hole and the corresponding positioning hole 200 relative to each other, and the positioning pin 210 is picked up and inserted into the fixing hole and the positioning hole 200 respectively, thereby completing the replacement of the winding wheel 160. The final effect is that different sizes of winding wheels 160 can be replaced on a set of bases 100 and stabilizing legs 110, so that the winding wheel 160 can be replaced at any time to meet the measurement of groundwater levels in different locations.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
