Description

TECHNICAL FIELD

[0001] This disclosure specifically relates to the technical field of water quality monitoring, and more specifically, to a device for monitoring water quality and a water level in a geological borehole. BACKGROUND

[0002] The monitoring of water quality and water levels in geological boreholes is of great importance for analyzing groundwater dynamics, evaluating slope stability, and monitoring pollutant migration. Currently, during monitoring applications, boreholes often exhibit significant water level fluctuations, active groundwater runoff, or localized water inflow and seepage phenomena. Such dynamic water environments can generate continuous or sudden lateral impact forces and eddy current disturbances on monitoring devices, which can easily cause the devices to tilt, flip, or even collide with the borehole walls.

[0003] Existing technologies mainly improve stability by adding support structures or optimizing the shape, but most of them are passive protection and cannot be actively adjusted according to real-time changes in the external fluid environment. Although sensors are introduced to sense the attitude, there is a lack of a quantifiable adjustment execution mechanism that is linked to the sensors. For example, when the device tilts, the system cannot precisely and stepwise increase the counterweight required for the restoring torque and can only perform rough “start and stop” control, which can easily lead to insufficient adjustment that fails to reset, or excessive adjustment that causes the device to sink too deeply or block the sampling port. SUMMARY

[0004] Therefore, this disclosure provides a device for monitoring water quality and a water level in a geological borehole, to solve the problems proposed in the above background.

[0005] To achieve the above purpose, this disclosure provides the following technical solutions: a device for monitoring water quality and a water level in a geological borehole, including:

[0006] a monitoring mechanism, internally provided with a water quality detector;

[0007] a ring carrier, fixed on a side portion of the monitoring mechanism, where a plurality of floating bases are fixed on the ring carrier in a circumferential array;

[0008] a central counterweight base, fixedly connected to a central position of a bottom surface of the monitoring mechanism by using a counterweight column;

[0009] collectors, where a plurality of collectors are disposed and annularly arranged on a side portion of the central counterweight base, and each of the collectors is connected to the water quality detector by using a pressure pipe; and

[0011] Optionally, a gravity source introduction mechanism is mounted on a bottom portion of each of the adjustable counterweight foot columns, and the gravity source introduction mechanism can introduce water into a water injection cavity of the adjustable counterweight foot column, thereby increasing the sinking gravity of the gravity source introduction mechanism.

[0012] Optionally, a plurality of partition bases are disposed in the water injection cavity of the adjustable counterweight foot column in an equidistant sealing manner, to form a plurality of unit cavities of the same volume in a partitioning manner, and a pressure injection mechanism is mounted on each of the partition bases.

[0013] Optionally, the gravity source introduction mechanism includes:

[0014] a driving housing, fixed on the bottom portion of the adjustable counterweight foot column, where a driving foot portion and a water pumping foot portion are disposed on both left and right sides of the driving housing respectively;

[0015] a driving wheel, rotatably mounted in the driving foot portion;

[0016] a driven wheel, in transmission connection with the driving wheel by using a transmission belt, where the driving wheel is driven by a waterproof motor fixed in the driving housing; and

[0017] a pressurization suction device, rotatably disposed between the driving foot portion and the water pumping foot portion, where the pressurization suction device can suck the water into the water injection cavity.

[0018] Optionally, one end portion of the pressurization suction device is connected to the driven wheel by using a transmission shaft, the other end portion of the pressurization suction device is in sealing adaptation with one end of a water introduction pipe, and the other end of the water introduction pipe is communicated with a water injection port of the water injection cavity of the adjustable counterweight foot column.

[0019] Optionally, a top surface of the partition base is provided with a groove opening, a bottom surface of the partition base is provided with a plurality of liquid inlet flow channels, and each of the liquid inlet flow channels is communicated with the groove opening.

[0020] Optionally, the pressure injection mechanism includes:

[0021] a sliding plug, disposed in the groove opening in an adapted sliding manner;

[0024] Optionally, a pressing pressure sensor is mounted on an end surface of the limiting disc close to the partition base.

[0025] Optionally, a position sensor and an inclination sensor are mounted in the monitoring mechanism.

[0026] This disclosure adopts the above technologies and has the following beneficial effects compared with the prior art: In the device of this disclosure, through the sensing of the position sensor and the inclination sensor, the device of this disclosure can automatically suck surrounding water as a counterweight according to external forces such as water level changes and water inflow impacts in the borehole, to adjust the overall center of gravity and draft in real time to resist interference.

[0027] That is, a sensor signal serves as precise feedback of “weight increase unit completion”, and the central processing unit can accurately determine how many “units” of counterweights have been added. When the device returns to balance (an inclination sensor signal is normal) or all unit cavities are about to be filled (the sensor is triggered continuously), the system can issue a water injection stop instruction. This achieves a closed-loop and quantitative counterweight adjustment, avoiding excessive weight increase or insufficient adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this disclosure. Apparently, the embodiments described below are merely some rather than all of the embodiments of this disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this disclosure without creative efforts shall fall within the protection scope of this disclosure.

[0039] Embodiment: referring to FIG. 1 to FIG. 6, this disclosure provides a technical solution: a device for monitoring water quality and a water level in a geological borehole, including:

[0040] a monitoring mechanism 1, internally provided with a water quality detector;

[0041] a ring carrier 2, fixed on a side portion of the monitoring mechanism 1, where a plurality of floating bases 3 are fixed on the ring carrier 2 in a circumferential array;

[0042] a central counterweight base 7, fixedly connected to a central position of a bottom surface of the monitoring mechanism 1 by using a counterweight column;

[0043] collectors 8, where a plurality of collectors are disposed and annularly arranged on a side portion of the central counterweight base 7, and each of the collectors 8 is connected to the water quality detector by using a pressure pipe 6; and

[0044] adjustable counterweight foot columns 4, having the same number as the floating bases 3 and fixed on a bottom portion of the ring carrier 2 in a circumferential array.

[0045] In this embodiment, a gravity source introduction mechanism 5 is mounted on a bottom portion of each of the adjustable counterweight foot columns 4, and the gravity source introduction mechanism 5 can introduce water into a water injection cavity 401 of the adjustable counterweight foot column 4, thereby increasing the sinking gravity of the gravity source introduction mechanism 5.

[0046] In this embodiment, a plurality of partition bases 402 are disposed in the water injection cavity 401 of the adjustable counterweight foot column 4 in an equidistant sealing manner, to form a plurality of unit cavities of the same volume in a partitioning manner, and a pressure injection mechanism is mounted on each of the partition bases 402.

[0047] It should be noted that the water injection cavity is partitioned into the plurality of unit cavities by the plurality of partition bases. During water injection, the water pressure needs to push open the sliding plug of each cavity one by one to allow water to be injected. This achieves a discontinuous and stepwise counterweight increase.

[0048] A counterweight of each foot column can be controlled independently. When water inflow occurs on one side of the borehole, causing the device to tilt toward an opposite side, the system may selectively increase the counterweight of the foot column below the water inflow side or reduce the counterweight on the opposite side, thereby quickly generating correction torque, which cannot be achieved by a single-column structure.

[0049] In this embodiment, the gravity source introduction mechanism 5 includes:

[0050] a driving housing 501, fixed on the bottom portion of the adjustable counterweight foot column 4, where a driving foot portion 504 and a water pumping foot portion 503 are disposed on both left and right sides of the driving housing 501 respectively;

[0051] a driving wheel 507, rotatably mounted in the driving foot portion 504;

[0052] a driven wheel 505, in transmission connection with the driving wheel 507 by using a transmission belt 506, where the driving wheel 507 is driven by a waterproof motor fixed in the driving housing 501; and

[0053] a pressurization suction device 502, rotatably disposed between the driving foot portion 504 and the water pumping foot portion 503, where the pressurization suction device 502 can suck the water into the water injection cavity 401.

[0054] In this embodiment, one end portion of the pressurization suction device 502 is connected to the driven wheel 505 by using a transmission shaft, the other end portion of the pressurization suction device 502 is in sealing adaptation with one end of a water introduction pipe, and the other end of the water introduction pipe is communicated with a water injection port 403 of the water injection cavity 401 of the adjustable counterweight foot column 4.

[0055] It should be noted that a water introduction end portion of the pressurization suction device 502 is provided with a filtering design, and is indirectly driven by the waterproof motor to reciprocate during working, so that blockages caused by larger sand grains or gravel can be avoided.

[0056] In this embodiment, a top surface of the partition base 402 is provided with a groove opening, a bottom surface of the partition base 402 is provided with a plurality of liquid inlet flow channels 408, and each of the liquid inlet flow channels 408 is communicated with the groove opening.

[0057] In this embodiment, the pressure injection mechanism includes:

[0058] a sliding plug 409, disposed in the groove opening in an adapted sliding manner;

[0059] a sliding rod 410, where one end portion of the sliding rod is fixedly connected to the sliding plug 409, and the other end portion penetrates downward and extends, and then is fixedly connected to a limiting disc 405; and

[0060] a spring 406, connected between the partition base 402 and the limiting disc 405 and wound on a side wall of the sliding rod 410, where under the support of an elastic force of the spring 406, the sliding plug 409 can block top end ports of the liquid inlet flow channels 408.

[0061] In this embodiment, a pressing pressure sensor 407 is mounted on an end surface of the limiting disc 405 close to the partition base 402.

[0062] It should be added that the distance between the limiting disc and the partition base can meet the condition that: under the driving of water injection pressure, the sliding plug 409 moves upward, and when the sliding plug is about to leave the groove opening, the pressing pressure sensor 407 can be in contact with the partition base 402 and issue a “stop” instruction to the pressurization suction device 502 through a central processing unit.

[0063] That is, the volume of one unit cavity is used as a weight increase unit, and in increments, the weight increase adjustment is performed on each adjustable counterweight foot column until the device of this disclosure is in a balanced state, thereby reducing the possibility of the device of this disclosure tipping over due to water inflow from the borehole wall.

[0064] In this embodiment, a position sensor and an inclination sensor are mounted in the monitoring mechanism 1.

[0065] That is, through the sensing of the position sensor and the inclination sensor, the device of this disclosure can automatically suck surrounding water as a counterweight according to external forces such as water level changes and water inflow impacts in the borehole, to adjust the overall center of gravity and draft in real time to resist interference.

[0066] That is, a sensor signal serves as precise feedback of “weight increase unit completion”, and the central processing unit can accurately determine how many “units” of counterweights have been added. When the device returns to balance (an inclination sensor signal is normal) or all unit cavities are about to be filled (the sensor is triggered continuously), the system can issue a water injection stop instruction. This achieves a closed-loop and quantitative counterweight adjustment, avoiding excessive weight increase or insufficient adjustment.

[0067] Although the embodiments of this disclosure have been shown and described, those of ordinary skill in the art may understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of this disclosure, and the scope of this disclosure is defined by the appended claims and their equivalents.
