Description

Technical Field

[0001] The utility model relates to the technical field of groundwater exploration, in particular to a groundwater detection device based on acoustic wave survey. Background Art

[0002] Groundwater is an important component of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industry, mining and cities. However, under certain conditions, changes in groundwater can also cause adverse natural phenomena such as swamping, salinization, landslides, and ground subsidence.

[0003] The existing groundwater acoustic wave detection device has certain drawbacks during use. The detection cable and the detection head are blocked by the wall of the detection borehole, which causes the cable to not always remain vertical and smoothly lowered to the bottom. After the detection cable is lowered to the detection borehole, the acoustic wave sensor cannot remain stable during the detection process due to the cable's own shaking, which can easily interfere with the accuracy of the detection data and affect the reliability of the read data. Utility Model Content

[0004] The purpose of the utility model is to provide a groundwater detection device based on acoustic wave survey to solve the above technical problems.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a groundwater detection device based on acoustic wave survey, comprising a detection device body, a cable is connected to the bottom of the detection device body, a fixing block is sleeved on the cable, a fixing plate and a support plate are connected below the fixing block, and two drill rods are installed through the support plate;

[0006] The fixing block includes a fixing seat, a screw, a slider, a first snap ring, a second snap ring, a second ball bearing, a first through groove, and a second groove. The cylindrical fixing seat is axially provided with a first through groove for vertically passing the cable, and radially provided with a second groove. A screw is provided in the second groove, and a second ball bearing fixedly connected to the second groove is sleeved at the front end of the screw. A slider is threadedly connected to the screw, and the slider is slidably connected to the second groove. The slider is connected to the first snap ring, and the first snap ring is slidably connected to the fixing seat. A second snap ring is provided on the opposite side of the first snap ring enclosing the first through groove; the second snap ring is fixedly connected to the fixing seat;

[0007] A motor is installed on the fixed plate, a power output shaft of the motor is sleeved with a driving wheel and is fixedly connected to a drill rod on the left side of the support plate, a first ball bearing is connected to the top of the drill rod on the right side of the support plate, the first ball bearing is fixedly connected to the fixed plate, a driven wheel is fixedly connected to the drill rod on the right side of the support plate, and a transmission belt is provided to connect the driving wheel and the driven wheel;

[0008] The cable passing through the fixed plate and the support plate is connected to the installation plate, and two second connecting rods are symmetrically installed on both sides of the installation plate. The second connecting rod is hinged with the first connecting rod through a pin shaft, and a universal wheel is installed on the end of the first connecting rod. Two symmetrical telescopic cylinders are installed at the bottom of the installation plate, and the telescopic ends of the telescopic cylinders are connected to drive blocks, and the drive blocks are fixedly connected to the first connecting rod. The bottom end of the cable is connected to a conical counterweight block, and a plurality of acoustic wave sensors are installed on the counterweight block.

[0009] Furthermore, an alarm light is fixedly provided on the top of the detection device body, and a touch switch is installed on the bottom of the counterweight block.

[0010] Furthermore, the touch switch is electrically connected to the warning light, and the acoustic wave sensor is electrically connected to the detection device body.

[0011] Furthermore, the telescopic cylinder is connected to a driving power source disposed in a detection device body.

[0012] Furthermore, a plurality of supporting legs are fixedly connected to the bottom of the detection device body, and the supporting legs are made of wood.

[0013] Furthermore, the counterweight block is made of cast iron, and the first connecting rod and the second connecting rod are both made of carbon steel.

[0014] The beneficial effect of the utility model is that the device can fix the cable at the center of the detection borehole through the fixing block and the fixing plate for lowering, thereby reducing obstacles in the lowering process.

[0015] The device is equipped with a telescopic cylinder to make the universal wheel contact the surface of the detection borehole. There is only a small rolling friction during the cable lowering process. Under the action of the universal wheel and the counterweight, the cable can always keep descending vertically to ensure that it does not shake. The acoustic sensor on the counterweight can stably collect data at different depths during the descent process. When it descends to the bottom of the borehole, the counterweight squeezes the touch switch at the bottom to trigger, and the staff knows that it has reached the bottom. The cable and the acoustic sensor can be reliably fixed at the bottom of the borehole by unfolding the second connecting rod and the first connecting rod through the telescopic cylinder.

[0016] When the acoustic wave sensor reaches the bottom of the borehole, the power output shaft of the motor drives the drill rod and the driving wheel to rotate. When the drill rod is completely drilled into the soil, the fixed block and the fixed plate are fixed, and the cable is clamped by moving the first clamp ring toward the second clamp ring. The cable is fixed at the upper end of the borehole. The cable remains vertical in the borehole without bending or shaking. The acoustic wave sensor can stably detect groundwater acoustic waves at the bottom of the borehole, ensuring the accuracy and reliability of acoustic wave survey data collection.

[0027] The fixed plate 23 is provided with a motor 20, a power output shaft of the motor 20 is sleeved with a driving wheel 14 and is fixedly connected to a drill rod 16 located on the left side of the support plate 15, a first ball bearing 18 is connected to the top of the drill rod 16 located on the right side of the support plate 15, the first ball bearing 18 is fixedly connected to the fixed plate 23, a driven wheel 17 is fixedly connected to the drill rod 16 located on the right side of the support plate 15, and a transmission belt 21 is provided to connect the driving wheel 14 and the driven wheel 17;

[0028] The cable 2 passing through the fixed plate 23 and the support plate 15 is connected to the installation plate 12, and two second connecting rods 13 are symmetrically installed on both sides of the installation plate 12.
