Description

[0002] Underwater oil production pipelines and other pipelines need to be cleaned regularly. Currently, a ball cleaner that can move inside the pipeline is mainly used to clean the pipeline. When the ball cleaner rolls inside the pipeline, it will rub against the pipeline and produce sound.

[0037] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0038] It should be noted that, in order to more clearly describe the detection device for the moving point of the underwater pipe cleaner in the present invention, the term "distal end" is defined below to mean the end of each component away from the pipe 4, and the "proximal end" is defined to mean the end of each component close to the pipe 4. Unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as those generally understood by technicians in the technical field of the present invention. The terms used in the present invention in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] like Figures 1 to 10 The present invention shows a detection device for detecting the moving point of an underwater pipe cleaner according to an embodiment of the present invention, which includes a support and fixing component 1, an acoustic wave detection component 2 and a self-locking component 3. The support and fixing component 1 is fixed on the outer wall of a pipe 4, and the support and fixing component 1 includes a receiving tube 101. The acoustic wave detection component 2 is detachably assembled in the receiving tube 101, and the acoustic wave detection component 2 includes a sensor 201. The self-locking component 3 is connected to the acoustic wave detection component 2 and is at least partially disposed in the storage tube 101. The self-locking component 3 includes a movable part 301, a clamping part 302 and an elastic part 303. The clamping part 302 is disposed in the circumferential direction of the movable part 301. The clamping part 302 is a columnar structure. The clamping part 302 is connected to the storage tube 101, thereby locking the self-locking component 3 and the acoustic wave detection component 2 in the storage tube 101. One end of the elastic part 303 is connected to the acoustic wave detection component 2, and the other end is connected to the movable part 301. The elastic part 303 has a tendency to drive the movable part 301 to move toward the far end of the storage tube 101.

[0040] According to the above embodiment, when the cleaner 5 moves in the underwater pipe 4 and cleans the pipe 4, when the cleaner 5 gradually approaches the sensor 201, the sensor 201 can receive the sound waves generated by the cleaner 5 rubbing against the inner wall of the pipe 4. And as the cleaner 5 approaches the sensor 201 from far to near, and then moves away from the sensor 201 from near to far, the sound amplitude received by the sensor 201 first gradually increases, and then gradually decreases. Therefore, after the detection device of the underwater pipe cleaner moving point of the above embodiment is installed at a specific part of the pipe 4, it can be judged whether the cleaner 5 has passed the specific part by the characteristics of the above sound amplitude. In addition, the sound wave detection component 2 in the working state can be effectively fixed by the self-locking component 3, which is convenient for the disassembly and assembly of the sound wave detection component 2. And the above embodiment does not need to groove the pipe 4, and has no adverse effect on the entire underwater pipe 4 system.

[0041] In one embodiment, the acoustic wave detection component 2 further includes an electrical socket 202, a circuit board 203 and a first wire 204. The circuit board 203 and the first wire 204 are arranged inside the acoustic wave detection component 2. The two ends of the first wire 204 are electrically connected to the circuit board 203 and the sensor 201 respectively. The circuit board 203 is electrically connected to the electrical socket 202. The circuit board 203 can directly convert the acoustic wave into an electrical signal underwater, thereby improving the working efficiency of the acoustic wave detection component 2. The electrical socket 202 can transmit the electrical signal.

[0042] Furthermore, due to the complexity of the underwater environment, it is difficult and costly to repair and replace the acoustic wave detection component 2 after it is damaged. In order to improve the stability of the acoustic wave detection component 2, the sensor 201 and the circuit board 203 can be designed redundantly. Specifically, the sensor 201 and the circuit board 203 are respectively provided with two, and two first wires 204 are connected to a single sensor 201, and a single first wire 204 of the first wires 204 is separately connected to a single circuit board 203. According to the above embodiment, when a certain sensor 201 is damaged, another sensor 201 can still work normally. Similarly, when a certain circuit board 203 is damaged, another circuit board 203 can still work normally, so the redundant design of the sensor 201 and the circuit board 203 greatly improves the stability of the acoustic wave detection component 2 when working underwater.

[0043] like Figure 6 As shown, the acoustic wave detection assembly 2 further includes a housing 205, the sensor 201 is mounted at the proximal end of the housing 205, a sealed electric control cavity 2051 is provided in the housing 205, and the circuit board 203 and the first wire 204 are mounted in the electric control cavity 2051. The electric control cavity 2051 can seal and protect the circuit board 203 and the first wire 204, thereby improving the service life and stability of the circuit board 203 and the first wire 204.

[0044] In one embodiment, in order to seal the electric control cavity 2051, the acoustic wave detection component 2 also includes a cover body 206, an isolation cover 207 and a third wire 208. The electric socket 202 is installed on the cover body 206. The proximal end of the cover body 206 extends into the shell 205 from the distal end of the shell 205. A through-bin cavity 2061 is provided in the cover body 206. The isolation cover 207 is installed between the through-bin cavity 2061 and the electric control cavity 2051, and seals the through-bin cavity 2061 and the electric control cavity 2051. The third wire 208 is electrically connected to the electric socket 202 and the circuit board 203 respectively.

[0045] After the electric control cavity 2051 and the through-warehouse cavity 2061 are sealed, in order to enable the circuit board 203 in the electric control cavity 2051 to still transmit electrical signals normally, the circuit board 203 is installed on the end face proximal to the isolation cover 207. The acoustic wave detection component 2 also includes a conductive sealing plug 209 and two second wires 210. The conductive sealing plug 209 is installed on the isolation cover 207. The two ends of the two second wires 210 are electrically connected to the conductive sealing plug 209 and different circuit boards 203 respectively. The other end of the conductive sealing plug 209 is electrically connected to the third wire 208. The conductive sealing plug 209 and the second wire 210 can smoothly transmit the electrical signal generated by the circuit board 203 to the electrical socket 202.

[0046] In one embodiment, the acoustic wave detection assembly 2 further comprises a pressure ring 211 threadedly connected to the inner wall of the housing 205, a second stopper 2052 is provided on the circumference of the inner side of the housing 205, the second stopper is formed by the inner wall of the housing 205 protruding inward, the end face of the proximal end of the isolation cover 207 abuts against the end face of the second stopper 2052, the end face of the proximal end of the pressure ring 211 abuts against the end face of the distal end of the isolation cover 207, the end face of the proximal end of the cover body 206 abuts against the end face of the distal end of the pressure ring 211, and the cover body 206 can be fixedly connected to the housing 205 by screws. According to the above embodiment, the position of the isolation cover 207 can be fixed by the pressure ring 211 and the second stopper 2052 to ensure the sealing effect of the isolation cover 207.

[0047] In order to protect the components such as the circuit board 203 in the electric control cavity 2051, the electric control cavity 2051 is filled with inert gas, and two through-holes 2071 are provided in the axial direction of the isolation cover 207, and a vent seal plug 212 is installed in each vent hole 2071. Specifically, when the inert gas is filled into the electric control cavity 2051, the isolation cover 207 is first installed without installing the vent seal plug 212, and then one of the vent holes 2071 is connected to the gas supply device, and the inert gas in the gas supply device is filled into the electric control cavity 2051, while the air is discharged from the electric control cavity 2051 through the other vent hole 2071, until the air in the electric control cavity 2051 is basically completely discharged, and then the vent seal plug 212 is installed to seal the vent hole 2071 to prevent the inert gas in the electric control cavity 2051 from leaking.

[0048] In one embodiment, in order to improve the sealing effect of the isolation cover 207, one or more first sealing rings 213 are installed on the circumference of the isolation cover 207. Similarly, in order to improve the sealing effect of the connection portion 218 between the cover body 206 and the shell 205, one or more second sealing rings 214 are installed on the circumference of the portion of the cover body 206 extending into the shell 205.

[0049] like Figure 6 and Figure 8 As shown, in order to protect the sensor 201, the acoustic wave detection assembly 2 further includes a guide seat 215 arranged around the sensor 201, the distal end of the guide seat 215 is connected to the proximal end of the housing 205, a first stopper 2011 is arranged on the outer circumference of the sensor 201, the first stopper 2011 can be an annular or multiple block-shaped plates, which are formed by the outer wall of the sensor 201 protruding outward, a third stopper 2151 is arranged on the inner circumference of the guide seat 215, the third stopper 2151 can be an annular or multiple block-shaped plates, which are formed by the inner wall of the guide seat 215 protruding inward, the third stopper 2151 presses the first stopper 2011 from the proximal end of the first stopper 2011, and then presses the first stopper 2011 against the end surface of the proximal end of the housing 205. In particular, in order to improve the sealing effect, the first stopper 2011 and the third stopper 2151 can adopt an annular plate.

[0050] In order to improve the sealing of the installation part of the sensor 201, the distal end of the sensor 201 extends into the end of the housing 205, and the end of the sensor 201 is provided with one or more third sealing rings 216, and the distal end of the first stopper 2011 is provided with one or more fourth sealing rings 217.

[0051] In one embodiment, the clamping member 302 can be clamped with the storage tube 101 to lock the movable member 301. Specifically, the distal end of the storage tube 101 is provided with a clamping groove 103 and a guide groove 104 that penetrate the tube wall of the storage tube 101. The clamping groove 103 and the guide groove 104 are arranged side by side along the circumference of the storage tube 101. The proximal end of the guide groove 104 is connected to the clamping groove 103 and the distal end extends to the end surface of the distal end of the storage tube 101. The movable member 301 can rotate in the storage tube 101, and the self-locking component 3 has a locked state and an unlocked state. In the locked state, the elastic member 303 presses the clamping member 302 into the clamping groove 103 to limit the acoustic wave detection component 2 from moving out of the storage tube 101. In the unlocked state, the movable member 301 rotates to make the clamping member 302 disengage from the clamping slot 103, and the elastic member 303 drives the clamping member 302 to move into the guide slot 104, so that the acoustic wave detection component 2 can be moved out of the storage tube 101.

[0052] In one embodiment, if Fig. 9 and Fig.10 As shown, the self-locking component 3 also includes a guide rod 304, a latch 305 and a pressure cover 306. A connecting portion 218 is provided on the end surface of the distal end of the acoustic wave detection component 2. The proximal end of the guide rod 304 is inserted into the connecting portion 218. The latch 305 is inserted into the connecting portion 218 and the guide rod 304 from the outside of the connecting portion 218 along the radial direction of the connecting portion 218. The elastic member 303 is a spring. A gasket 310 can be provided at the distal end of the elastic member 303 to reduce the resistance of the movable member 301 when rotating. The elastic member 303 is sleeved on the guide rod 304. The movable member 301 01 is a cover-like structure and is sleeved on the distal end of the guide rod 304. The pressure cover 306 is detachably fixed on the end face of the distal end of the guide rod 304. The pressure cover 306 is used to limit the movable part 301 from being separated from the guide rod 304 from the distal end of the guide rod 304. The proximal end of the guide seat 215 is provided with a coupling portion 2152. The proximal end of the coupling portion 2152 is a recessed structure. The contour of the recessed structure is consistent with the contour of the pipe 4, so that the coupling portion 2152 fits with the outer wall of the pipe 4, thereby limiting the rotation of the acoustic wave detection component 2 when the movable part 301 is rotated.

[0053] According to the above embodiment, the movable member 301 can move along and around the guide rod 304, and under the restriction of the pressure cover 306, the movable member 301 cannot be separated from the guide rod 304. Therefore, when the self-locking component 3 is in a locked state, pressing the movable member 301 can make the clamping member 302 move to the proximal end of the guide groove 104, and then rotating the movable member 301 can make the clamping member 302 screw into the clamping groove 103, and use the resilience of the elastic member 303 to lock the self-locking component 3, and then lock the acoustic wave detection component 2 connected to the self-locking component 3. When the self-locking component 3 needs to be changed from the locked state to the unlocked state, the movable member 301 is pressed again and rotated or the movable member 301 is directly rotated, so that the clamping member 302 is screwed out from the clamping groove 103 to the guide groove 104. It should be noted that the clamping groove 103 and the guide groove 104 can be arranged in a J-shape or an L-shape as a whole.

[0054] When the self-locking assembly 3 and the acoustic wave detection assembly 2 are installed into the storage tube 101, in order to stabilize the position of the movable member 301 in the unlocked state and prevent the movable member 301 from rotating, it is convenient to align the clamping member 302 with the guide groove 104. In one embodiment, a boss 3061 is provided at the proximal end of the pressure cover 306, a penetrating coupling hole 3011 is provided in the axial direction of the movable member 301, the cross-sectional size of the pressure cover 306 is larger than the cross-sectional size of the coupling hole 3011, a first groove 3012 connected to each other is provided on the side of the coupling hole 3011, and the lateral size of the first groove 3012 is larger than the lateral size of the boss 3061, the guide rod 304 passes through the coupling hole 3011, and a second groove 3041 is provided on the end surface of the distal end of the guide rod 304, which is arranged radially and penetrates the guide rod 304, and the boss 3061 extends from the distal end of the guide rod 304 into the second groove 3041 and extends from the second groove 3041 along the radial direction of the guide rod 304.
