Description

Technical Field

[0001] The invention relates to the technical field of groundwater level detection equipment, and in particular to a groundwater level real-time detection device for engineering geological survey. Background Art

[0002] Well drilling is one of the most widely used methods for groundwater level monitoring. The water level at the bottom of the wellbore is directly observed by drilling the wellbore, thereby obtaining real-time observation data of the groundwater level. This method has high accuracy and reliability in shallow groundwater level monitoring, and is particularly suitable for monitoring wells with small apertures and shallow heights.

[0003] Traditional devices for detecting groundwater levels usually use a connecting rope connected to the detection device to observe the groundwater level under the action of the detection device; however, when placing and taking the device, the detection head will collide with the inner wall when rising and falling in the observation well, which can easily cause a certain impact on the detection equipment and may affect the detection accuracy of the equipment.

[0004] Secondly, for equipment that detects groundwater levels for a long time, when the humidity in the observation well is too high, water film or water droplets may form on the sensor surface, which will change the sensor readings and lead to inaccurate detection results. In addition, long-term moisture may also affect the sensitivity of the sensor, further reducing its accuracy. Since the equipment needs to perform real-time detection, its use environment makes it inconvenient to maintain.

[0005] Therefore, there is an urgent need for a real-time groundwater level detection device for engineering geological survey to solve the above-mentioned problems. Summary of the invention

[0006] In order to solve the technical problem in the background technology that the detection equipment is inconvenient to maintain during long-term use, which easily affects the observation accuracy of the equipment and reduces the service life of the equipment, the present invention provides a real-time groundwater level detection device for engineering geological survey.

[0007] The present invention is implemented by the following technical scheme: A real-time groundwater level detection device for engineering geological survey comprises:

[0008] ground;

[0009] A detection well, wherein the detection well is opened on the ground;

[0010] A cover, which is movably installed on the upper end of the ground and is located directly above the detection well;

[0011] A winding mechanism, wherein the winding mechanism is arranged in the cover, and the winding mechanism comprises a winding and releasing component and an adapting component;

[0012] A shell body, wherein the shell body moves in the detection well and the top end of the shell body is connected to the winding mechanism;

[0013] A protection mechanism, wherein the protection mechanism is arranged around the shell;

[0014] A dehumidification mechanism is arranged at the bottom end of the shell.

[0015] Through the above technical scheme, the connecting rope can be better stored by utilizing the retractable assembly, and can be synchronously displaced and moved with the cooperation of the adaptable assembly to ensure uniformity of the retractable assembly; and when the entire device is placed in the detection well, several groups of protective mechanisms can be utilized to protect the device body to avoid direct collision with the inner wall of the detection well; the dehumidification mechanism can automatically clean and dehumidify under the action of buoyancy and the pull of the connecting rope.

[0016] As a further improvement of the above scheme, the winding assembly includes a motor, which is fixedly installed in the cover, and a rotating shaft is fixedly connected to the output end of the motor. The rotating shaft is fixedly connected to a belt pulley and a winding reel in sequence from the inside to the outside, and the other end of the rotating shaft is rotatably connected to the cover, a connecting rope is wrapped around the outer wall of the winding reel, and a cable for data transmission is arranged inside the connecting rope.

[0017] As a further improvement of the above scheme, the adaptation component includes an upper plate, the upper end of the upper plate is symmetrically rotatably connected to gear three and gear four, chains are sleeved on the outside of gear three and gear four, one side of the upper plate is horizontally slidably connected to a sleeve plate, one side of the upper plate is fixedly connected to a positioning plate, and the connecting rope can pass through the sleeve plate and the positioning plate in turn and slide therein.

[0018] As a further improvement of the above scheme, the bottom end of gear three is fixedly connected to gear two, and gear two is rotatably connected to the connection point of the upper plate. One side of gear two is meshingly connected to gear one, and the outer end of gear one is fixedly connected to rotating rod one, and rotating rod one is rotatably connected to one side of the upper plate. The outer side of rotating rod one is fixedly connected to belt pulley two, and belts are sleeved on the outer sides of belt pulley two and belt pulley one.

[0019] Through the above technical scheme, the belt pulley 1 and the winding disk can be driven synchronously by the drive of the motor, and under the action of the belt and the belt pulley 2, the gear 1 on the upper plate will drive the gear 2 that is meshed with it, and then the gear 3 drives the chain to drive the gear 4 to rotate, so that the sleeve plate can drive the connecting rope to be stored and unfolded, and the positions of the two are adapted to each other.

[0020] As a further improvement of the above scheme, the upper end of the chain is fixedly connected to a vertical rod, the vertical rod is rotatably connected to a swivel, one side of the swivel is fixedly connected to a slider, the slider is horizontally slidably connected to a sleeve block, and one side of the sleeve block is fixedly connected to the outer wall of the sleeve plate.

[0021] Through the above technical solution, the rotation of the chain is utilized to drive the vertical rod to pull the swivel, so as to realize the adaptive displacement sliding of the slider on the sleeve block, and make the sleeve plate slide horizontally on one side of the upper plate to meet the adaptation of the connecting rope winding.

[0022] As a further improvement of the above scheme, the protection mechanism includes vertical grooves evenly opened at the upper and lower ends of the outer wall of the shell, and the vertical grooves are at least three groups. Corresponding buffer units are relatively slidably connected in the multiple groups of vertical grooves, and the top of the shell is fixedly connected to the connecting rope.

[0023] As a further improvement of the above scheme, the number of the buffer unit is consistent with that of the vertical grooves. The buffer unit includes a sliding block 1, a hinged rod 1 and a sliding block 2. The sliding block 1 and the sliding block 2 slide at the upper and lower ends of the vertical groove respectively. One side of the sliding block 1 is hinged to the hinged rod 1, and the outer end of the hinged rod 1 is rotatably connected to the rotating rod 2. The middle part of the rotating rod 2 is fixedly connected to an abutment wheel, and one side of the sliding block 2 is hinged to the hinged rod 2. The hinged rod 2 is rotatably connected to the two ends of the rotating rod 2, and the abutment wheel rolls on the inner wall of the detection well.

[0024] Through the above technical solution, the abutment wheels arranged on all sides can preferentially abut against the inner wall of the detection well to prevent the equipment from directly colliding with the inner wall of the detection well when being placed or recovered, thereby ensuring that under the action of multiple groups of buffer units, the components inside the equipment are prevented from being damaged.

[0026] Through the above technical scheme, the elasticity of the movable sleeve can be utilized to push the positioning block and displace the abutment wheel in the horizontal direction. Since the sliding block 1 and the sliding block 2 at the upper and lower ends can slide adaptively, they can meet the needs of fitting detection wells with different apertures and abut against the inner wall of the detection well, thereby completing the mobile positioning of the equipment.

[0028] Through the above technical solution, the weight of the shell itself plus the counterweight block are utilized in conjunction with the retracted connecting rope, so that resistance is generated when the movable rod contacts the water surface, and the movable rod is pushed upward, and the shell descends, thereby driving the internal cleaning unit to move, and driving the cleaning unit back and forth during repeated retraction and extension.

[0029] As a further improvement of the above scheme, annular grooves are symmetrically provided on both sides of the bottom plate, and a cleaning unit is symmetrically slidably connected in the annular groove. The cleaning unit includes a sliding block three, and the sliding block three is slidably connected in the annular groove. The upper end of the sliding block three is fixedly connected to a guide plate, and a guide groove is provided on one side of the guide plate. A cross bar is slidably connected in the guide groove, and the cross bar is fixedly installed on both sides of the fixed plate. The bottom end of the sliding block three is fixedly connected to an L-shaped plate, and one side of the L-shaped plate is fixedly connected to a cotton body, and the cotton body slides against the sensor.

[0030] Through the above technical scheme, the movable rod is driven upward by the thrust generated by the movable rod and the water level, and the two sets of guide plates are synchronously rotated under the sliding of the cross bar and the guide groove, so as to further realize the scraping of the cotton body at the bottom end against the sensor, and squeeze out the moisture from the cotton body under the contact with the side plate.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) The present invention utilizes the cooperation of the dehumidification mechanism and the winding mechanism to drive the equipment for automatic cleaning to ensure the accuracy of detection, and can transmit data information back from the connecting rope to ensure data transmission and detection accuracy.
