Description

Technical Field

[0001] The present invention relates to the technical field of geological monitoring, and more particularly to a monitoring device for hydrogeological survey. Background Art

[0002] In karst areas, pollution sources such as intensive livestock and poultry farming, chemical emissions, and farmland fertilization often converge in fragile geological units such as sinkholes and karst depressions. The combined effects of strong tectonic uplift and river incision have led to the development of a highly complex underground karst network in the region, forming multiple interlaced surface and underground streams. This unique hydrogeological structure provides an efficient migration channel for pollutants. Pollutants can easily seep directly into the ground through surface depressions and sinkholes, and quickly spread along the developed underground pipeline network, eventually merging into the underground river system. Therefore, in order to accurately assess the intensity of pollution sources, migration paths, and pollution control effects, it is necessary to carry out quantitative research and testing on the analysis of groundwater pollution sources.

[0003] In underwater environmental monitoring, the probe is exposed to complex flowing water bodies for a long time and faces multiple threats. The mud, gravel or floating objects carried by high-speed water flow can easily cause impact damage to the probe shell, which not only affects the measurement accuracy but may also directly lead to equipment failure. In addition, the probe is easily entangled by aquatic plants and wraps the lower part of the probe, forming a physical constraint on the probe, which not only interferes with its free flow positioning and affects the alignment accuracy, but may also hinder the water flow from contacting key sensing parts, resulting in systematic measurement deviations. For this reason, we propose a monitoring device for hydrogeological surveys. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1 further describes a monitoring device for hydrogeological surveys proposed by the present invention, including a monitoring head 100, wherein the bottom end of the monitoring head 100 is recessed upward to form a stepped groove 101, a cavity 102 is formed in the monitoring head 100, and an electric push rod 103 is detachably mounted on the cavity 102. The electric push rod 103 is adjusted by a corresponding controller, and the output end of the electric push rod 103 is located at one end of the stepped groove 101 and is mounted with a probe 104. An annular groove 105 is formed inside the stepped groove 101, and a protective structure 200 is disposed in the annular groove 105.

[0035] Since the lower part of the probe 104 is easily entangled and wrapped by water plants, a physical constraint is formed on the probe 104, which not only interferes with its free flow positioning and affects the alignment accuracy, but is also likely to hinder the water flow from contacting the key sensing parts, resulting in systematic measurement deviations. The present device improves the structure of the monitoring head 100, and the probe 104 is installed inside the monitoring head through an electric push rod 103. The probe 104 is retracted into the protective structure 200 through the vertical displacement of the probe 104. The monitoring head 100 is provided with a stepped groove 101, and the stepped groove 101 gradually increases in diameter from top to bottom. The stepped groove 101 is provided with an annular groove 105, and the protective structure 200 is provided in the annular groove 105. The protective structure 200 includes a driving member 201 arranged in the monitoring head 101, a ring member 202 is provided in the monitoring head 100, and an adjusting member 203 is provided on the ring member 202. The ring member 202 and the adjusting member 203 cooperate to protect the probe 104.

[0036] As can be seen from the above, the annular member 202 and the adjusting member 203 cooperate to protect the probe 104. When the probe 104 is not in use, the adjusting member 203 is provided with an alternating protective cover 1 203a and a protective cover 2 203b to protect the probe 104. When in use, the annular member 202 and the adjusting member 203 cooperate to open the protective space formed by the protective cover 1 203a and the protective cover 2 203b. The probe 104 only needs to be driven downward by the electric push rod 103. At this time, the probe 104 monitors the water body.

[0037] Since the bottom of the monitoring head 100 is easily entangled and wrapped by water plants, the present device is further provided with an auxiliary mechanism 300, which includes a rotating member 301 provided at the bottom of the monitoring head 100, a movable member 302 provided inside the rotating member 301, and a resistance member 303 provided on the outer wall of the rotating member 301. During the use of the monitoring head 100, the annular member 202 drives the rotating member 301 to move synchronously during operation. At this time, the movable member 302 and the resistance member 303 cooperate to remove the water plants at the bottom of the monitoring head 100;

[0038] The present device further improves the internal structure of the monitoring head 100 and includes a cleaning mechanism 400. The cleaning mechanism 400 includes an auxiliary member 401 disposed on the circular plate 201d, and a cleaning member 402 is disposed in the cavity 102. When the monitoring head 100 is in use, its annular member 202 drives the auxiliary member 401 to operate synchronously. The auxiliary member 401 and the cleaning member 402 cooperate to clean the outer side of the probe 104 in the vertical direction, thereby ensuring the stability of the monitoring head 100 during use.

[0039] Working principle: When the monitoring head 100 is in use, the protective space composed of the protective cover 1 203a and the protective cover 2 203b is opened through the cooperation of the annular part 202 and the adjusting part 203, and then the electric push rod 103 is started by the external controller. The electric push rod 103 drives the probe 104 to move downward. At this time, the probe 104 monitors the water body. During the operation, the annular part 202 drives the rotating part 301 to move synchronously. At this time, the movable part 302 and the resistance part 303 cooperate to remove the water plants at the bottom of the monitoring head 100. At the same time, the annular part 202 drives the auxiliary part 401 to operate synchronously, and the auxiliary part 401 and the cleaning part 402 cooperate to clean the outside of the probe 104 in the vertical direction to ensure the stability of the probe 104 when in use.

[0040] Example 2, based on Example 1, adds the following technical features: the driving member 201 includes a driving chamber 201a provided in the monitoring head 100, the driving chamber 201a is connected to the stepped groove 101, a motor 201b is detachably installed in the driving chamber 201a, the motor 201b is adjusted by a corresponding controller, the rotor shaft end of the motor 201b is fixedly connected to the gear 201c, a circular plate 201d is rotatably connected in the annular groove 105, a ring gear 201e is fixedly connected to the outer wall of the circular plate 201d, the ring gear 201e is engaged with the gear 201c, the annular member 202 includes a protrusion 202a integrally formed at the bottom end of the circular plate 201d, a center hole 202b is provided in the protrusion 202a, the probe 104 is correspondingly provided in the center hole 202b, and a plurality of groups of arc grooves 202c are provided on the outer wall of the protrusion 202a;

[0041] A cylindrical drive chamber 201a is formed in the monitoring head 100. A motor 201b is detachably installed in the drive chamber 201a. The motor 201b is started by a corresponding controller, and the motor 201b drives the gear 201c to rotate. Since the ring gear 201e is engaged with the gear 201c, the ring gear 201e drives the circular plate 201d to rotate. The rotation of the circular plate 201d also drives the protrusion 202a to rotate. The protrusion 202a is a cylindrical structure with four groups of arc grooves 202c surrounding its outer side. At the same time, a cylindrical center hole 202b is formed in its center. The probe 104 passes through the corresponding center hole 202b.

[0042] The adjusting member 203 includes two groups of protective covers 1 203a and protective covers 203b. The protective covers 1 203a and protective covers 203b cooperate with each other to form a protective portion 203c. The diameter of one group of protective portions 203c is larger than that of the other group. The adjusting member 203 also includes an adjusting platform 203d. The protective portion 203c is stuck in the adjusting platform 203d. The bottom end of the adjusting platform 203d is provided with a circumferential groove 203e. The inner side of the protective cover 1 203a is fixedly connected to a locking portion 1 203f. The side of the locking portion 1 203f is fixedly connected to a positioning strip 1 203g. The inner end of the protective cover 1 203a away from the locking portion 1 203f is fixedly connected to an insert portion 203 3h, a second locking portion 203i is fixedly connected to the inner side of the second protective cover 203b, a second positioning strip 203j is fixedly connected to the side wall of the second locking portion 203i, a second plug-in block 203k is fixedly connected to the inner end of the second protective cover 203b away from the second locking portion 203i, the first locking portion 203f and the second plug-in block 203k cooperate with each other, the second locking portion 203i cooperates with the first plug-in block 203h, a second locking slot 203l is provided at the corresponding positions of the first protective cover 203a and the second protective cover 203b, the first plug-in block 203h and the second plug-in block 203k cooperate with the second locking slot 203l, and the first positioning strip 203g and the second positioning strip 203j are correspondingly slidably connected within the arcuate groove 202c;

[0043] Depend on Figures 5 to 10 It can be seen that the protective portion 203c is composed of two groups of protective covers 1 203a and protective covers 203b. The protective cover 1 203a and the protective cover 2 203b form two groups of protective portions 203c. The diameter of one group of protective portions 203c is larger than the diameter of the other group, which is convenient for the two groups of protective portions 203c to cooperate with each other, and the smaller diameter is inserted into the larger diameter protective portion 203c. The protective cover 1 203a and the protective cover 2 203b rotate with each other, and the protective cover 1 203a and At the corresponding position of the second protective cover 203b, the locking portion 1 203f and the second inserting block 203k cooperate, and the locking portion 203i cooperates with the first inserting block 203h. In this way, the first protective cover 203a and the second protective cover 203b can rotate relative to each other, and the first inserting block 203h and the second inserting block 203k cooperate with the second locking groove 203l. At the same time, the protrusions 202a of the first inserting block 203h and the second inserting block 203k are respectively engaged in the first locking groove 203e.

[0044] Since the side wall of the second locking portion 203i is fixedly connected to the second positioning bar 203j, the side wall of the first locking portion 203f is fixedly connected to the first positioning bar 203g, and the first positioning bar 203g and the second positioning bar 203j are correspondingly slidably connected in the arc groove 202c, when the circular plate 201d drives the arc groove 202c on the protruding portion 202a to rotate synchronously, due to the deflection force of the arc groove 202c, the first positioning bar 203g and the second positioning bar 203j are deflected following the curvature of the arc groove 202c, thereby driving the two sets of protective portions 203c to rotate relative to each other. Figure 10 It can be seen that the protective cover 1 203a and the protective cover 2 203b rotate relative to each other to adjust the opening size of the adjustment platform 203d. When rotating clockwise, the opening size of the adjustment platform 203d is maximized, and the probe 104 can pass through the adjustment platform 203d. When rotating counterclockwise, the opening of the adjustment platform 203d is closed.

[0045] Working principle: As can be seen from embodiment 1, the motor 201b is started by the controller, and the motor 201b drives the gear 201c to rotate. Since the ring gear 201e is engaged with the gear 201c, the ring gear 201e drives the circular plate 201d to rotate. The circular plate 201d rotates while driving the protrusion 202a to rotate. The arc groove 202c on the protrusion 202a rotates synchronously. Due to the deflection force of the arc groove 202c, the positioning bar 203g and the positioning bar 203g are rotated. The second position strip 203j follows the arc of the arc groove 202c-1 and deflects. At this time, the two sets of protective parts 203c rotate relative to each other, and the protective cover 1 203a and the protective cover 2 203b rotate relative to each other, which adjusts the opening size of the adjustment platform 203d. When rotating clockwise, the opening size of the adjustment platform 203d is the largest, and the probe 104 can pass through the adjustment platform 203d. When rotating counterclockwise, the opening of the adjustment platform 203d is closed to prevent foreign matter from affecting the probe 104.

[0046] In summary, the device adjusts the opening size of the adjustment platform 203d in a stable and controllable manner. This action not only isolates interference such as external water impact, large floating objects impact, and instantaneous biological contact, but also effectively protects the precision probe 104 in the core position from physical damage and contamination during the non-working state and mobile startup phase. Therefore, the spatial isolation structure formed by the two sets of protective parts 203c ensures that the probe 104 is only exposed to the water body during a safe "window period", providing a better direction for subsequent acquisition of high-quality data.

[0047] Example 3 adds the following technical features on the basis of Example 2: its auxiliary mechanism 300 includes a rotating member 301 provided at the bottom end of the monitoring head 100, a movable member 302 is provided in the rotating member 301, and a resistance member 303 is provided on the outer wall of the rotating member 301, the movable member 302 and the resistance member 303 cooperate with each other, the rotating member 301 includes an arc-shaped hole 301a circumferentially provided in the annular groove 105, the bottom end of the circular plate 201d is circumferentially fixedly connected to a connecting plate 301b, multiple groups of connecting plates 301b are fixedly connected to the outside of the protective ring 301c, the center of the protective ring 301c is formed with a through hole 301d, and its probe 104 correspondingly passes through the through hole 301d;

[0048] Depend on Figures 2 to 5 It can be seen that the bottom diameter of the stepped groove 101 is relatively large, and an annular groove 105 is provided in the stepped groove 101, and an arc-shaped hole 301a is symmetrically provided in the annular groove 105. The bottom end of the circular plate 201d is symmetrically fixed with a connecting plate 301b, and the connecting plate 301b is correspondingly slidably connected in the arc-shaped hole 301a. Therefore, when the connecting plate 301b rotates, it drives the protective ring 301c to rotate synchronously.

[0049] The movable part 302 includes a sliding hole 302a arranged in a circle in the protective ring 301c, and a plurality of sliding holes 302a are slidably connected to the sliding rod 302b. The side wall of the sliding rod 302b is fixedly connected to the compression spring 302c. The compression spring 302c is a carbon spring with high strength and easy to use. The compression spring 302c is fixedly connected to the inner wall of the protective ring 301c. The bottom end of the sliding rod 302b is fixedly connected to the movable plate 302d. The corresponding positions of the plurality of movable plates 302d are formed with an arc surface. 302e, the interference member 303 includes a notch 303a provided on the movable plate 302d, a collar 303b rotatably connected to the outer wall of the protective ring 301c, a torsion spring 303c fixedly connected inside the collar 303b, one end of the torsion spring 303c fixedly connected to the outer wall of the protective ring 301c, a reducing portion 303d formed in a circumferential manner on the outer wall of the collar 303b, the reducing portion 303d correspondingly provided in the notch 303a, and the reducing portion 303d interferes with the movable plate 302d;

[0050] Depend on Figures 4 to 7The cam 302a is fixed to the cam 302b at the bottom end of the cam 302c, and the cam 302b is fixed to the cam 302c at the bottom end of the cam 302c. The cam 302a is fixed to the cam 302b at the bottom end of the cam 302c. The cam 302b is fixed to the cam 302d at the bottom end of the cam 302c. The cam 302d is fixed to the cam 302d at the bottom end of the cam 302c. The cam 302d is fixed to the cam 302d at the bottom end of the cam 302c.

[0051] The present device further defines the structure of the movable plate 302d. An elongated notch 303a is formed at the upper end of the movable plate 302d, and three sets of reducing portions 303d are circumferentially fixed to the outer side of the collar 303b. The reducing portions 303d have increasing diameters and abut against the notch 303a. Therefore, when the collar 303b is rotated, the collar 303b drives the reducing portions 303d to come into contact with the movable plate 302d, thereby driving the multiple sets of movable plates 302d to move outward.

[0052] Working principle: It can be seen from Example 2 that when in use, the circular plate 201d rotates, driving the protective ring 301c at the bottom of the connecting plate 301b to rotate synchronously. When the protective ring 301c rotates, the movable plate 302d rotates synchronously. When the probe 104 moves downward, the probe 104 contacts the curved surface 302e on the movable plate 302d, causing the three groups of movable plates 302d to move outward, thereby removing the water plants at the lower end of the monitoring head 100. When it is necessary to clean the inside of the monitoring head 100, it is only necessary to rotate the collar 303b. The collar 303b drives the reducing portion 303d to conflict with the movable plate 302d, thereby driving multiple groups of movable plates 302d to move outward, making it easier for staff to clean the inside.

[0053] In summary, when the two sets of protective parts 203c move, the auxiliary mechanism 300 driven by the annular part 202 drives the movable part 302 and the resistance part 303 to work together, and prevent the entanglement and cut and remove the water plants, algae or flexible impurities that pose the greatest threat to the bottom of the monitoring head 100 in real time. At the same time, the movable part 302 and the resistance part 303 cooperate to facilitate cleaning by the staff.

[0054] Example 4, based on Example 3, adds the following technical features: the auxiliary member 401 includes an auxiliary ring 401a fixedly connected to the circular plate 201d, and the auxiliary ring 401a is formed with a wave groove 401b. The cleaning member 402 includes an auxiliary rod 402a movably connected to the cavity 102, and an auxiliary spring 402b is sleeved on the outer wall of the auxiliary rod 402a. The auxiliary spring 402b is a carbon spring with high strength and easy to use. One end of the auxiliary rod 402a is in conflict with the wave groove 401b. Two groups of cleaning rings 402c are sleeved on the outer wall of the probe 104, and a connecting rod 402d is fixedly connected between the two groups of cleaning rings 402c. The side wall of the auxiliary rod 402a is fixedly connected to a connecting portion 402e, and the connecting portion 402e is fixedly connected to the outer wall of the cleaning ring 402c.

[0055] The present device further defines the structure of the circular plate 201d, wherein a wave groove 401b structure is formed on its upper end, and an auxiliary rod 402a is provided in the vertical direction in the cavity 102. The auxiliary rod 402a is connected to the inner wall of the cavity 102 by an auxiliary spring 402b. When the top of the wave groove 401b contacts the auxiliary rod 402a, the auxiliary rod 402a is driven to move upward. When the concave portion of the wave groove 401b contacts the auxiliary rod 402a, the auxiliary rod 402a is driven to move downward under the action of the auxiliary spring 402b. When used in this manner, the cleaning ring 402c is moved on the surface of the probe 104 by the rotation of the circular plate 201d.

[0056] Working principle: As can be seen from Example 3, when the circular plate 201d rotates, it drives the wave groove 401b on the auxiliary ring 401a to rotate synchronously. When the top of the wave groove 401b contacts the auxiliary rod 402a, it drives the auxiliary rod 402a to move upward. When the concave part of the wave groove 401b contacts the auxiliary rod 402a, the auxiliary rod 402a is driven downward by the action of the auxiliary spring 402b. When used in this way, the rotation of the circular plate 201d causes the cleaning ring 402c to move on the surface of the probe 104. Therefore, when the protective structure 200 is in use, its two sets of cleaning rings 402c clean the surface of the probe 104;

[0057] In summary, when the protective cover is opened and the water body is monitored, the annular member 202 is used to drive the auxiliary mechanism 300 to remove the water plants at the bottom of the probe 104, and at the same time drives the auxiliary cleaning mechanism 400 to automatically clean the outer wall of the probe 104, thereby realizing the protection of the probe 104, water body parameter collection and synchronous self-cleaning functions of key components during the monitoring process, and effectively ensuring the stability and reliability of the monitoring data.
