Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-3 , a combined fish top fishing integrated device, which includes a sub 1. A guide shoe 2 is fixedly connected to the bottom of the sub 1. A sizing cylinder 3 is fixedly connected to the bottom of the guide shoe 2. A repair inner cylinder 4 is fixedly installed inside the guide shoe 2. A conical mandrel 5 is fixedly connected to the bottom of the repair inner cylinder 4. A guiding tool 6 is movably connected to the bottom of the guide shoe 2. The setting of the guiding tool 6 is beneficial for the fish to enter the guide shoe 2 through the guiding tool 6. A flushing water channel 7 is provided on the conical mandrel 5. A connection structure 8 is provided between the guide shoe 2 and the guiding tool 6. An intelligent control component 9 is provided inside the guide shoe 2. The inner diameter of the guiding tool 6 is the same as that of the guide shoe 2. The sizing cylinder 3 is a flared sizing cylinder.

[0028] Specifically, the intelligent control component 9 is composed of three components: a sensor module 901, an image recognition and monitoring module 902, and a communication module 903. By providing a sensor module 901 inside the guide shoe 2, an image recognition and monitoring module 902 inside the guide shoe 2, and a communication module 903 inside the guide shoe 2, the output ends of the sensor module 901, the image recognition and monitoring module 902, and the communication module 903 are electrically connected to the input end of an external controller. The sensor module 901 uses pressure sensors to monitor the changes in tension and pressure, and monitors the liquid level height through a liquid level sensor. Then, the data collected by the sensors is transmitted to the external controller for analysis and decision-making, so as to analyze and judge the fishing situation in real time. By providing the image recognition and monitoring module 902, image recognition and monitoring of the target fishing object are realized by using a camera, so as to capture images and videos in the well and provide clear image and video streams for automatically identifying the target fishing object and monitoring the fishing process. By providing the communication module 903, communication with the external controller is enabled to realize data transmission and command interaction with the external system.

[0029] Specifically, the connection structure 8 is composed of seven components: a clamping groove 801, a clamping block 802, a housing 803, a spring 804, a positioning block 805, a pull rod 806, and a positioning groove 807. By opening clamping grooves 801 on both the left and right sides at the bottom of the guide shoe 2, clamping blocks 802 are fixedly connected to both the left and right sides at the top of the guide cylinder 6. Housing 803s are fixedly installed on both the left and right sides of the guide shoe 2. Two springs 804 are fixedly connected inside the housing 803. A positioning block 805 is slidably connected inside the housing 803. A pull rod 806 is fixedly connected to the outer surface of the positioning block 805. Positioning grooves 807 are opened on the opposite sides of the two clamping blocks 802. By adopting a detachable installation between the guide cylinder 6 and the guide shoe 2, the guide cylinder 6 is convenient to replace and maintain. During disassembly, pull the two pull rods 806 outwards, so that while moving, the positioning block 805 is driven to separate from the positioning groove 807, and then the limit of the clamping block 802 disappears, and the guide cylinder 6 can be disassembled. It is convenient to use, without borrowing too many tools, and can also prevent the trouble of losing parts during the disassembly process.

[0030] Specifically, the sensor module 901 includes a pressure sensor and a liquid level sensor. The pressure sensor is used to monitor the changes in tension and pressure, and the liquid level sensor monitors the liquid level height. Then, the data collected by the sensor is transmitted to an external controller for analysis and decision-making.

[0031] Specifically, the image recognition monitoring module 902 is a camera, which uses the camera to realize image recognition and the monitoring of the target salvage object, so as to capture the images and videos in the well and provide clear image and video streams for automatically identifying the target salvage object and monitoring the salvage process.

[0032] Specifically, the communication module 903 is a wireless communication module, so as to communicate with an external controller and realize data transmission and command interaction with an external system.

[0033] Specifically, the inner wall of the clamping groove 801 fits with the outer surface of the clamping block 802. First through holes are opened on the adjacent sides of the two housings 803. The positioning block 805 is clamped with the positioning groove 807 through the first through hole, and then the positioning block 805 is clamped with or separated from the positioning groove 807 through the first through hole.

[0034] Specifically, second through holes are opened on the opposite sides of the two housings 803, and the pull rod 806 extends to the outside of the housing 803 through the second through hole, which makes it convenient for the user to operate.

[0035] Specifically, one side of the spring 804 is fixedly connected to the inner wall of the housing 803, and the other side of the spring 804 is fixedly connected to the outer surface of the positioning block 805. Then, the elastic force of the spring 804 can be used to drive the positioning block 805 to move.

[0036] During use, with the intelligent control component 9, in cooperation with the sensor module 901, the image recognition and monitoring module 902, and the communication module 903, when the fish-down is introduced into the guide shoe 2, the guide shoe 2 itself has a centering effect. Using the external drill string weight, the conical mandrel 5 can be centered into the center of the fallen object in any state for fishing. When removing the guide barrel 6, pull the two pull rods 806 outwards. While moving, it drives the positioning block 805 to separate from the positioning groove 807, thereby eliminating the limit of the clamping block 802, and then the guide barrel 6 can be disassembled.

[0037] In summary, for this combined fish-down fish head fishing integrated device, by setting the intelligent control component 9, the sensor module 901 uses pressure sensors to monitor the changes in tension and pressure, and uses liquid level sensors to monitor the liquid level height. Then, the data collected by the sensors is transmitted to an external controller for analysis and decision-making, so as to analyze and judge the fishing situation in real time. By setting the image recognition and monitoring module 902, image recognition and monitoring of the target fishing object are realized by using a camera, so as to capture images and videos in the well and provide clear image and video streams for automatically identifying the target fishing object and monitoring the fishing process. By setting the communication module 903, communication with an external controller is enabled to realize data transmission and command interaction with an external system. The external system uses big data analysis and machine learning technologies to analyze and process the data collected during the fishing process. Through learning from historical data and pattern recognition, real-time decision support can be provided to help operators optimize fishing strategies and parameter settings, thereby improving the success rate of fishing efficiency, further enhancing the automation level of the fish-down fish head fishing device, and realizing more intelligent, efficient, and reliable fishing operations. This will help improve operation efficiency, reduce labor input, and reduce risks and uncertainties during the fishing process, solving the problems that the existing fish-down fish head fishing devices have a relatively low automation level, may have certain inconveniences and uncertainties in operation, human factors will affect the fishing effect, and to a certain extent, affect the safety and efficiency of operation.

[0038] Moreover, by setting the connection structure 8, since the guide barrel 6 and the guide shoe 2 are detachably installed, the guide barrel 6 is convenient to replace and maintain. When disassembling, pull the two pull rods 806 outwards. While moving, it drives the positioning block 805 to separate from the positioning groove 807, thereby eliminating the limit of the clamping block 802, and then the guide barrel 6 can be disassembled. It is convenient to use, without borrowing too many tools, and can also prevent the trouble of losing parts during the disassembly process. At the same time, it can avoid the nuts being exposed outside for a long time and being easily corroded by rainwater, etc., resulting in inconvenient subsequent disassembly and assembly or affecting its installation firmness and stability.
