Description

Technical Field

[0001] The present invention belongs to the technical field of groundwater detection, and particularly relates to a detection device and control method for self-cleaning groundwater. Background Art

[0002] Underwater surveillance devices such as underwater cameras play an important role in the related detection of groundwater. However, due to the presence of a large amount of impurities and pollutants in groundwater, the surface of any object placed in groundwater will soon be covered by a layer of impurities and pollutants, which adhere to other surveillance devices such as the underwater camera lens and will affect the normal use of the device.

[0003] After retrieval, in the prior art, the publication number (the publication number for the authorized one): CN211043430U, the publication date: July 17, 2020, discloses a device for monitoring the flow direction and velocity of groundwater, including a first underwater detector housing and a second underwater detector housing. The first underwater detector housing and the second underwater detector housing are connected by a connecting rod. Inside the first underwater detector housing, a vibration motor and a backlight are sequentially arranged from bottom to top. At the top of the first underwater detector housing, a first sapphire glass window and a pressure and temperature sensor are arranged. The backlight is located directly below the first sapphire glass window; at the bottom of the second underwater detector housing, a second sapphire glass window is arranged. Inside the second underwater detector housing, a microscopic lens, a camera, a central processing unit, an electronic compass, a serial communication module, and a power module are sequentially arranged from bottom to top; the serial communication module is connected to a ground controller. This application can accurately monitor the flow direction and velocity of groundwater in real time by shooting the direction of the water flow with a camera, and obtain the water depth and temperature data at the monitoring position without complex operations.

[0004] However, this device still has the following defects: Although it can accurately monitor the flow direction and velocity of groundwater in real time by shooting the direction of the water flow with a camera, when this device monitors groundwater, the impurities and pollutants in the groundwater will adhere to the glass window and cannot perform self-cleaning operations, thus affecting the normal shooting of the camera. When the device needs to be cleaned, the device needs to be pulled out of the water for manual cleaning, which not only has a large workload but also affects the normal monitoring progress.

The water quality of the groundwater is photographed by the camera 6 to visually detect the groundwater environment. The detection data is transmitted through the cable 4 to the display on the shore by the control circuit board 9 for display and storage. When it is observed through the display that the captured image of the camera 6 is blurred, it indicates that impurities and pollutants are attached to the outside of the perspective window 7. The cleaning assembly 8 is controlled to move downward to the perspective window 7 to clean the impurities and pollutants on the outer wall of the perspective window 7, so that the image captured by the camera 6 remains clear.

[0043] The cleaning assembly 8 includes an outer ring body 801; Exemplarily, as Figures 3-6 shown.

The perspective window 7 is cleaned by the cleaning assembly 8. After the cleaning is completed, the outer ring body 801 is driven to move in the reverse direction through several groups of propulsion mechanisms 803 until the two groups of limiting rings 802 respectively contact and attract the two groups of first limiting blocks 10, completing the reset of the cleaning assembly 8 and avoiding the cleaning assembly 8 from blocking the perspective window 7 and affecting the shooting picture of the camera 6.

[0046] A first motor 8041 is installed in the transmission box 804. The output end of the first motor 8041 is drivingly connected with a driving gear 8042.

An ultrasonic generating mechanism 808 is embeddedly installed on the inner wall of the inner ring body 805;

[0047] Specifically, ultrasonic waves are emitted through the ultrasonic generating mechanism 808 to clean the outer wall of the perspective window 7. The driving gear 8042 is driven to rotate by the first motor 8041, so that the external gear ring 806 drives the inner ring body 805 to rotate, enabling the ultrasonic generating mechanism 808 to emit ultrasonic waves to different positions of the perspective window 7, improving the cleaning effect. The spiral stirring blade 807 is driven to rotate by the inner ring body 805, accelerating the water flow speed outside the perspective window 7, so that the impurities and pollutants after cleaning are separated from the perspective window 7 and flow out quickly with the water flow, effectively avoiding the secondary adhesion of impurities and pollutants.

[0048] A limiting groove 8011 is opened on the inner wall of the outer ring body 801. The limiting groove 8011 is in movable fit with the external gear ring 806. A sliding groove 8012 is opened at the top end of the inner wall of the limiting groove 8011. A ring-shaped conductive sheet 8013 is laid in the sliding groove 8012.

[0050] Specifically, while the inner ring body 805 drives the ultrasonic generating mechanism 808 to rotate synchronously, the conductive block 8085 fits in the slide groove 8012 and maintains contact with the annular conductive sheet 8013, so that the conductive block 8085 maintains electrical connection with the annular conductive sheet 8013 during movement, thereby realizing continuous power supply to several groups of ultrasonic generators 8082 during rotation, avoiding wire entanglement caused by traditional wire connection methods.

[0051] The propulsion mechanism 803 includes a bracket 8031; illustratively, Figure 7 and Figure 8 shown.

[0052] The bracket 8031 ​​is fixedly connected to the side wall of the detector housing 1, and a flip box 8032 is arranged on the bracket 8031. A second motor 8039 is installed in the flip box 8032. The other end of the flip box 8032 is rotatably connected to a linkage block 8033. The linkage block 8033 is transmission-connected to the output end of the second motor 8039. A clamping ring 8034 is fixedly connected to the linkage block 8033. A driving box 8035 is installed in the clamping ring 8034. , a deflector 8036 is provided at the bottom end of the driving box 8035, a third motor 80310 is installed in the driving box 8035, an output end of the third motor 80310 is drivingly connected to a rotating shaft 8037, a side wall of the rotating shaft 8037 is provided with a plurality of groups of propeller blades 8038, the plurality of groups of propeller blades 8038 are distributed in a circular array with the central axis of the rotating shaft 8037 as the center, and the plurality of groups of propeller blades 8038 are arranged inside the deflector 8036;

[0053] Specifically, the third motor 80310 drives the rotation of the rotating shaft 8037, causing several groups of propeller blades 8038 to rotate synchronously, realizing the propulsion of the outer ring body 801. The second motor 8039 drives the rotation of the linkage block 8033, causing the drive box 8035 to drive the fairing 8036 and the propeller blades 8038 to flip 180 degrees, enabling the propeller blades 8038 to drive the outer ring body 801 to propel in the reverse direction, realizing the automatic reset of the outer ring body 801.

[0054] The working principle of a self-cleaning groundwater detection device proposed by the present invention is as follows:

[0055] The cable 4 drives the detector housing 1 into the groundwater. The water quality detection mechanism detects the water quality of the groundwater. The camera 6 takes pictures of the water quality of the groundwater to visually detect the groundwater environment. The control circuit board 9 transmits the detection data through the cable 4 to a display on the shore for display and storage. When the picture taken by the camera 6 is observed to be blurred through the display, it indicates that impurities and pollutants are attached to the outside of the perspective window 7. The cleaning component 8 is controlled to move downward to the perspective window 7 to clean the impurities and pollutants on the outer wall of the perspective window 7, keeping the picture taken by the camera 6 clear.

[0056] Several groups of propulsion mechanisms 803 drive the outer ring body 801 to move to the outside of the perspective window 7. At this time, the two limit rings 802 respectively fit on the two limit shafts 12 and move downward until they contact and attract each other with the two second limit blocks 11, realizing the limit fixation of the cleaning component 8. The cleaning component 8 cleans the perspective window 7. After the cleaning is completed, several groups of propulsion mechanisms 803 drive the outer ring body 801 to move in the reverse direction until the two limit rings 802 respectively contact and attract each other with the two first limit blocks 10, completing the reset of the cleaning component 8, avoiding the cleaning component 8 from blocking the perspective window 7 and affecting the picture taken by the camera 6.

[0057] The third motor 80310 drives the rotation of the rotating shaft 8037, causing several groups of propeller blades 8038 to rotate synchronously, realizing the propulsion of the outer ring body 801. The second motor 8039 drives the rotation of the linkage block 8033, causing the drive box 8035 to drive the fairing 8036 and the propeller blades 8038 to flip 180 degrees, enabling the propeller blades 8038 to drive the outer ring body 801 to propel in the reverse direction, realizing the automatic reset of the outer ring body 801.

[0058] Ultrasonic waves are emitted by the ultrasonic generating mechanism 808 to clean the outer wall of the perspective window 7. The first motor 8041 drives the driving gear 8042 to rotate, so that the outer gear ring 806 drives the inner ring body 805 to rotate, and the ultrasonic generating mechanism 808 emits ultrasonic waves to different positions of the perspective window 7 to improve the cleaning effect. The spiral stirring blade 807 is driven to rotate by the inner ring body 805 to accelerate the water flow speed outside the perspective window 7, so that the cleaned impurities and pollutants are separated from the perspective window 7 and flow out quickly with the water flow, effectively avoiding the secondary attachment of impurities and pollutants.

[0059] While the inner ring body 805 drives the ultrasonic generating mechanism 808 to rotate synchronously, the conductive block 8085 fits in the slide groove 8012 and keeps in contact with the annular conductive sheet 8013, so that the conductive block 8085 maintains electrical connection with the annular conductive sheet 8013 during movement, thereby realizing continuous power supply to several groups of ultrasonic generators 8082 during rotation, avoiding wire entanglement caused by traditional wire connection methods.

[0060] Based on the above-mentioned self-cleaning groundwater detection device, the embodiment of the present invention further proposes a control method for the detection device. Exemplarily, the control method includes:

[0061] The cable drives the detector housing into the groundwater, and the water quality testing agency tests the water quality;

[0062] The camera takes pictures of water quality and conducts visual inspection of the groundwater environment;

[0063] The control circuit board transmits the detection data via cables to the display on shore for display and storage;

[0064] When the camera image is observed to be blurred through the display, the third motor is turned on to drive the propeller blades to rotate, pushing the outer ring body to move downward until the two sets of limit rings contact the second limit blocks and attract each other, and then the third motor is turned off, and the cleaning component moves to the outside of the perspective window;

[0065] Control the ultrasonic generator to start, and emit ultrasonic waves to clean the attachments on the perspective window;

[0066] The first motor is controlled to start, and the inner ring body drives the spiral stirring blade and the ultrasonic generator to rotate;

[0067] The ultrasonic generator rotates to clean different positions around the perspective window, and the spiral stirring blades rotate to drive the water outside the perspective window to flow quickly, taking away the cleaned attachments with the water flow;

[0068] After the self-cleaning operation of the perspective window is completed, the ultrasonic generator is powered off and the first motor is turned off;

[0069] Turn on the second motor to drive the fairing and the propeller blades to flip, then turn on the third motor. The rotation of the propeller blades drives the outer ring body to move upward until the two sets of limit rings contact the first limit block and attract each other, and then turn off the third motor to complete the reset of the cleaning component.

[0070] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
