[0023] Compared with the comparative documents, through the implementation of this embodiment, the free-diving detector weighted probe 12 provided in the present invention can avoid the interference of external factors such as surface vibration and soil characteristics, which helps to reduce measurement errors and improve the accuracy and reliability of data.

[0024] For further examples, please refer to Figures 1 to 7 As shown: The end of the conversion chamber 34 away from the push plate 33 is fixedly connected with a one-way liquid inlet valve, and the end of the one-way liquid inlet valve away from the conversion chamber 34 is fixedly connected with a liquid collecting chamber 35, the liquid collecting chamber 35 is installed on the outer surface of the winding cover 1, the cleaning agent 11 is threadedly connected to the upper surface of the liquid collecting chamber 35, and the conversion chamber 34 is also provided with a water outlet hole on the side close to the one-way liquid inlet valve, and the water outlet hole is fixedly connected with a one-way water outlet valve, and at the same time, the one-way water outlet valve is fixedly connected with a cleaning chamber 36 at one end away from the conversion chamber 34, the cleaning chamber 36 is fixedly connected to the inner wall of the winding cover 1, and the cleaning chamber 36 is respectively arranged on the upper and lower sides of the outer surface of the tape measure 13; The measuring and positioning mechanism 4 comprises a debris removal chamber 41, an oil collecting chamber is provided in the middle of the debris removal chamber 41, the outer surface of the tape measure 13 passes through the middle of the debris removal chamber 41, the upper end of the debris removal chamber 41 is fixedly connected to the bottom of the winding cover 1, a slide groove is provided at one end of the debris removal chamber 41 away from the winding cover 1, a positioning clamping plate 42 is symmetrically slidably connected in the slide groove of the debris removal chamber 41, a sliding tooth plate 44 is fixedly connected to one end of the positioning clamping plate 42, a positioning arrow 46 is fixedly connected to the upper surface of the other end of the positioning clamping plate 42, a meshing gear 45 is meshed on the tooth surface of the sliding tooth plate 44, and the middle part of the meshing gear 45 is rotatably connected to the bottom of the debris removal chamber 41; Wherein: a pattern recognition controller 43 is installed at the bottom of the positioning clamp plate 42, a micro motor is installed at the bottom of the impurity removal chamber 41, and the micro motor drive shaft is fixedly connected to the middle of the meshing gear 45, and the pattern recognition controller 43 is electrically connected to the micro motor; Graphic recognition controller 43: Use image recognition technology, such as edge detection, contour extraction, etc., to identify the scale on the tape measure 13. This step requires precise positioning of each scale line and calculation of the spacing between them. After the scale lines are identified, they need to be converted into specific values. When the scale value reaches a preset threshold, a braking signal is triggered to start the device; when the scale value is lower than the threshold, a start signal is triggered to stop the device.

[0025] Compared with the comparative document, through the implementation of this embodiment, it is possible to preliminarily remove large particles of impurities attached to the surface of the tape measure 13 during the winding process, effectively ensuring the accuracy of subsequent detection and the stable operation of the equipment, and when the detector weight probe 12 dives to a preset depth under the precise control of the operator, the graphic recognition controller 43 device starts the motor at the bottom of the impurity removal chamber 41 through the setting controller of the terminal program. By clamping the surface of the tape measure 13 by the graphic recognition controller 43, it can not only ensure that the tape measure 13 can stay stably in the current position, but also avoid falling off or deviation in a complex environment.

[0026] Everything in the above example works like this: In the initial state: the motor is not started and the buffer spring 29 is not compressed.

[0027] The following is the working process of the anti-loosening mechanism 2 for preventing the tape measure 13 from loosening when detecting the thickness of the oil reservoir: When in use, the operator first manually presses the buffer spring 29 on the reserved oil hole. At this time, the tape measure 13 is fixedly connected to the outer surface of the reel 23 at one end, and the other end is installed on the detector weight probe 12. Due to the self-weight of the detector weight probe 12 and the action of gravity, the outer surface of the tape measure 13 slides on the first roller 25 and the second roller 26 respectively. Therefore, the detector weight probe 12 will drive the tape measure 13 to slide on the surface of the first roller 25 and the second roller 26. Since the detector weight probe 12 starts to drive the tape measure 13 through the bottom, the reel 23 rotates counterclockwise around the reel cover. 1 inner wall, at this time, because the operator manually presses the Z-shaped anti-slip plate 28 away from one end of the tape measure 13, because the middle part of the Z-shaped anti-slip plate 28 rotates on the inner wall of the winding cover 1, at this time, because one end of the buffer spring 29 is fixedly connected to the upper surface of the Z-shaped anti-slip plate 28, and the other end is fixedly connected to the bottom of the winding cover 1, the buffer spring 29 begins to be stretched, and the clockwise rotation of the Z-shaped anti-slip plate 28 makes the Z-shaped anti-slip plate 28 fit the surface of the tape measure 13. Since the bottom of the Z-shaped anti-slip plate 28 is provided with an anti-skid groove, the friction between the anti-skid groove of the Z-shaped anti-slip plate 28 and the surface of the tape measure 13 causes the tape measure 13 to drive the reel 23 to stop rotating; At this time, when the operator releases the pressure on the Z-shaped anti-skid plate 28, the buffer spring 29 will start to rotate counterclockwise under the elastic action of the buffer spring 29 itself. At this time, the Z-shaped anti-skid plate 28 is no longer in contact with the surface of the tape measure 13, and under the action of gravity of the detector weight probe 12, it starts to move shallower into the oil hole again. According to the arrangement of the present invention, the operator can manually press the Z-shaped anti-skid plate 28 to control the detector weight probe 12 to perform detection at different depths in the surveyed oil hole, and the operator can manually control the diving depth of the detection device in the surveyed oil hole, which means that the measurement work is no longer limited to a fixed depth setting, but can be flexibly adjusted according to actual needs. This flexibility is particularly important for the complex and changeable oil reservoir environment, and can ensure that the measurement work covers the target reservoir more accurately.

[0028] Please refer to the above working process Figures 1 to 7 .

[0029] The following is the working process of the measuring and positioning mechanism 4 for measuring and positioning the thickness of the oil reservoir: Under the above settings, after the operator sets the diving threshold value inside the graphic recognition controller 43, the operator can freely control the diving start and stop of the tape measure 13 under the relative control of the Z-shaped anti-slip plate 28. When the graphic recognition controller 43 detects the scale of the tape measure 13 diving up and down, the graphic recognition controller 43 uses image recognition technology, such as edge detection, contour extraction, etc., to identify the scale on the tape measure 13. This step requires accurate positioning of each scale line and calculation of the spacing between them. After identifying the scale lines, they need to be converted into specific values. When the scale value reaches the preset threshold, the braking signal is triggered to start the equipment. Since the graphic recognition controller 43 is electrically connected to the motor at the bottom of the impurity removal chamber 41, the motor will start to drive the meshing gear 45 to start rotating in the clockwise direction. Since the sliding gear plate 44 is symmetrically meshed on both sides of the meshing gear 45, because the graphic recognition controller 43 slides symmetrically in the impurity removal chamber 41, and the working principle is the same, only the following is done. Figure 5 A group is described, at this time, through the meshing action of the meshing gear 45 and the sliding tooth plate 44, when the meshing gear 45 rotates clockwise, it will drive the sliding tooth plate 44 to drive the fixedly connected graphic recognition controller 43 to start clamping the surface of the tape measure 13. At this time, since the positioning clamping plate 42 is provided with a pressure sensor device inside, the motor can be controlled to stop running under the control of the pressure sensor device; When the detector weight probe 12 dives to the threshold value, the graphic recognition controller 43 automatically clamps the surface of the tape measure 13 to prevent it from detaching. This can not only preliminarily remove large particles of impurities attached to the surface of the tape measure 13 during the winding process, effectively ensuring the accuracy of subsequent detection and the stable operation of the equipment, but also when the detector weight probe 12 dives to the preset depth under the precise control of the operator, the graphic recognition controller 43 device starts the motor at the bottom of the impurity removal chamber 41 through the setting controller of the program threshold of the terminal. Through the clamping of the surface of the tape measure 13 by the graphic recognition controller 43, it can not only ensure that the tape measure 13 can stay stably in the current position to avoid falling off or offset in a complex environment, but also provide intuitive visual feedback to the operator through the design of the meshing gear 45 device. Through it, the operator can clearly see the diving scale, thereby realizing precise control of the diving depth of the equipment. This design not only greatly improves the convenience of operation.

[0030] Please refer to the above working process Figures 1 to 7 .

[0031] When the detector weight probe 12 completes the detection of the oil reservoir in the oil hole, the operator can turn the crank 21 clockwise again. Figure 6As shown, because the reel 23 is fixedly connected to the middle of the one-way shaft 31, and because the one-way shaft 31 adopts a one-way transmission shaft and can only rotate in the clockwise direction but cannot rotate in the counterclockwise direction, the rotation of the one-way shaft 31 will drive the crank 32 to drive the push plate 33 to slide in the conversion chamber 34. At this time, the cleaning liquid in the detergent 11 is sucked into the conversion chamber 34 through the air pressure conversion between the push plate 33 and the conversion chamber 34. Since the conversion chamber 34 is fixedly connected to a one-way liquid inlet valve at one end away from the push plate 33, and the one-way liquid inlet valve is far away from the end of the conversion chamber 34. The conversion chamber 34 is fixedly connected with a liquid collecting chamber 35, and a water outlet hole is also opened on the side of the conversion chamber 34 close to the one-way liquid inlet valve, and the water outlet hole is fixedly connected with a one-way water outlet valve, and at the same time, the one-way water outlet valve is fixedly connected with a cleaning chamber 36 at one end away from the conversion chamber 34, so the cleaning liquid in the cleaning agent 11 can be transmitted to the cleaning chamber 36 through a certain pressure through the conversion chamber 34, and the surface of the tape measure 13 can be cleaned by spraying it onto the surface of the tape measure 13 through the cleaning chamber 36, and after the cleaning chamber 36 cleans the surface of the tape measure 13, the surface of the tape measure 13 can be wiped again by the cleaning rod to reduce The cleaning agent in the cleaning agent 11 can timely and effectively clean the impurities and oil stains attached to the surface of the measuring tape 13, which can effectively prevent the unevenness of the rolling caused by the rolling of the measuring tape 13. At the same time, because the transmission belt 24 is far away from the end of the reel 23 and is connected to the first roller 25, the middle parts of the two ends of the first roller 25 are rotatably connected to the inner wall of the winding cover 1, and the outer surface of one end of the first roller 25 is provided with a meshing groove, and a second roller 26 is arranged below the first roller 25, and the two ends of the second roller 26 are rotatably connected to the winding cover 1. The inner wall of the roll cover 1 and the outer surface circumference of one end of the second roller 26 are provided with meshing teeth, and the meshing teeth of the second roller 26 are meshed in the meshing groove opened in the first roller 25. The exquisite rolling and winding design of the first roller 25 and the second roller 26 in the present invention can ensure that the tape measure 13 remains tight during the winding process and effectively avoids the occurrence of looseness. In this way, when the detector weight probe 12 is put into use again for diving, it can enjoy a smoother and more stable operation experience, and at the same time, it also greatly reduces the risk of damage to the equipment due to looseness or impurities adhesion.
