Description

Technical Field

[0001] The present invention relates to the technical field of endoscope flushing, and in particular to an endoscope flusher capable of flushing at multiple angles. Background Art

[0002] Industrial endoscopes can be used for inspection and observation of high temperature, toxic, nuclear radiation and places that cannot be directly observed by the human eye. They are mainly used in automobiles, aircraft engines, pipelines, mechanical parts, etc. They can achieve non-destructive testing without disassembling or destroying the assembly and stopping the equipment. On the other hand, industrial endoscopes can also be connected to cameras, video cameras or electronic computers to form photography, video and image processing systems, so as to monitor, record, store and analyze images of field targets. This provides a good guarantee for diagnosis and treatment.

[0003] A water jet mechanism is installed on the basis of the endoscope, thereby forming an endoscope with the function of cleaning the inside of the pipeline.

[0004] Traditional endoscope flushers lack the ability to clean the inside of the pipeline at multiple angles, which reduces the efficiency of pipeline cleaning. In addition, the rotation and movement of the endoscope need to be controlled by the direction of water discharge. Due to the lack of precise control, the accuracy of steering and movement is low. Therefore, an endoscope flusher that can flush at multiple angles is needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an endoscope flusher capable of flushing at multiple angles.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An endoscope flusher capable of flushing at multiple angles, comprising an image acquisition unit, the exterior of which is further provided with a drive unit, a water pump unit, and a cleaning unit; an end of the cleaning unit is provided with a circular ball head for discharging water, the exterior of the circular ball head being provided with a drainage hole;

[0008] A positioning ring is installed inside the cleaning unit, a cleaning nozzle for spraying water is movably provided inside the cleaning unit, a locking plate is installed at the bottom of the cleaning nozzle, and a card block is installed outside the locking plate, and a transmission mechanism for driving the locking plate is provided inside the cleaning unit.

[0009] The above technical solution further includes:

[0010] The transmission mechanism comprises a support plate installed inside the cleaning unit, an electric lifting rod is installed outside the support plate, and a positioning plate is installed at the output end of the electric lifting rod.

[0011] A support rod is rotatably installed on the side of the positioning plate away from the electric lifting rod. The outside of the support rod is rotatably connected to a hollow rod, and a rotating mechanism for driving the hollow rod is installed inside the cleaning unit. By setting up the rotating mechanism, the hollow rod starts to rotate, thereby causing the transmission plate to start rotating, ensuring multi-angle cleaning of the cleaning nozzle.

[0012] The rotating mechanism includes a driving motor installed inside the cleaning unit, a rotating ring is installed at the end of the output shaft of the driving motor, a conveyor belt is wound around the outside of the rotating ring, the conveyor belt is wound around the outside of the hollow rod, and the hollow rod and the rotating ring are connected through a conveyor belt transmission.

[0013] A transmission plate is installed on one end of the support rod away from the positioning plate, and the hollow rod is connected to the bottom of the transmission plate, and the support rod passes through the transmission plate.

[0014] Four locking grooves are provided on the outside of the transmission plate, and a locking strip adapted to the locking groove is installed on the side of the locking plate away from the cleaning nozzle. The locking groove and the locking strip can be used to position the locking plate, and the cross-section of the transmission plate is sloped, so that the direction of the water flow from the cleaning nozzle at this time deviates from the central axis of the cleaning unit.

[0015] A water tank is installed inside the cleaning unit, a transmission pipe is installed between the water tank and the cleaning nozzle, a plurality of positioning grooves are evenly opened on the inner circumference of the positioning ring, and the clamping block is slidably connected to the inner part of the positioning groove.

[0016] A square groove is provided inside the locking plate, and a spherical groove is also provided inside the locking plate, which is connected to the square groove. A movable ball is movably provided inside the locking plate, and the movable ball is connected to the end of the support rod. A spring is symmetrically installed outside the movable ball, and one end of the spring away from the movable ball is connected to the inside of the square groove;

[0017] Since the four springs are symmetrically arranged, when the locking strip is separated from the locking slot, the locking plate and the support rod remain in a vertical state, thereby facilitating the subsequent clamping of the clamping block with the interior of the positioning slot.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, when in use, the locking plate and the positioning ring are used in conjunction to make the block close to the inside of the positioning groove, thereby positioning the locking plate, avoiding shaking of the cleaning nozzle during the flushing process, and ensuring stability during flushing.

[0020] In the present invention, during use, when it is necessary to flush the inside of the pipe at multiple angles, the locking plate is moved downward by driving the electric lifting rod. During the movement, the locking plate causes the locking bar to be tightly pressed against the locking groove to achieve the positioning of the locking plate, and the cross-section of the transmission plate is sloped, so that the spray direction of water from the cleaning nozzle deviates from the central axis of the cleaning unit. Then the driving motor is started, and the driving motor drives the hollow rod to start rotating through the conveyor belt during the rotation process. During the rotation process, the hollow rod drives the locking plate to start rotating through the transmission plate. The locking plate is in an inclined state at this time, and in the process of rotating along the central axis of the cleaning unit, the water flow sprayed from the cleaning nozzle can deviate from the central axis of the cleaning unit, thereby increasing the cleaning efficiency of the pipe.

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0030] like Figure 1-7 As shown, the present invention proposes an endoscope flusher capable of multi-angle flushing, comprising an image acquisition unit 1, the image acquisition unit 1 is further provided with a drive unit 2, a water pump unit 3 and a cleaning unit 4 on the outside, the end of the cleaning unit 4 is provided with a circular ball head 5 for discharging water, and the outside of the circular ball head 5 is provided with a drainage hole;

[0031] A positioning ring 14 is installed inside the cleaning unit 4, and a cleaning nozzle 19 for spraying water is movably provided inside the cleaning unit 4. A locking plate 12 is installed at the bottom of the cleaning nozzle 19, and a card block 20 is installed outside the locking plate 12. A transmission mechanism for driving the locking plate 12 is provided inside the cleaning unit 4, and a plurality of positioning grooves 18 are evenly arranged on the inner circumference of the positioning ring 14, and the card block 20 is slidably connected to the inner part of the positioning groove 18.

[0032] The working principle of the multi-angle flushing endoscope flusher according to the first embodiment is as follows: when in use, the image acquisition unit 1 captures the image inside the pipe, the drive unit 2 drives the image acquisition unit 1, so that the angle of the image acquisition unit 1 can be adjusted, and the water pump unit 3 is provided with a water flow control module to transport the external water flow to the inside of the water tank 6 through the pipe;

[0033] During the initial cleaning, the block 20 is made to enter the positioning groove 18. At this time, the block 20 is close to the inside of the positioning groove 18, thereby positioning the locking plate 12 and preventing the cleaning nozzle 19 from shaking during the flushing process, thereby ensuring stability during flushing. The cleaning nozzle 19 is then started, and the cleaning nozzle 19 draws the water flow inside the water tank 6 through the transmission pipe 13, and then sprays it out through the cleaning nozzle 19. The sprayed water flows along the central axis of the cleaning unit 4, thereby achieving initial cleaning of the pipeline. Example 2

[0034] like Figure 1-7 As shown, based on the first embodiment, the transmission mechanism includes a support plate installed inside the cleaning unit 4, an electric lifting rod 7 is installed on the outside of the support plate, and a positioning plate 8 is installed on the output end of the electric lifting rod 7;

[0035] A support rod 15 is rotatably mounted on one side of the positioning plate 8 away from the electric lifting rod 7. The outside of the support rod 15 is rotatably connected to the hollow rod 10, and a rotating mechanism for driving the hollow rod 10 is installed inside the cleaning unit 4. The rotating mechanism includes a drive motor 9 installed inside the cleaning unit 4. A rotating ring 16 is installed on the end of the output shaft of the drive motor 9. A conveyor belt 17 is wound around the outside of the rotating ring 16. The conveyor belt 17 is wound around the outside of the hollow rod 10, and the hollow rod 10 and the rotating ring 16 are connected by the conveyor belt 17.

[0036] A transmission plate 11 is mounted on the end of the support rod 15 away from the positioning plate 8, and the hollow rod 10 is connected to the bottom of the transmission plate 11. The support rod 15 passes through the transmission plate 11. Four locking grooves 22 are opened on the outside of the transmission plate 11. A locking strip 21 adapted to the locking groove 22 is mounted on the side of the locking plate 12 away from the cleaning nozzle 19.

[0037] A water tank 6 is installed inside the cleaning unit 4, and a transmission pipe 13 is installed between the water tank 6 and the cleaning nozzle 19. A square groove 25 is provided inside the locking plate 12, and a spherical groove 23 connected to the square groove 25 is also provided inside the locking plate 12. A movable ball 24 is movably provided inside the locking plate, and the movable ball 24 is connected to the end of the support rod 15. A spring 26 is symmetrically installed on the outside of the movable ball 24, and the end of the spring 26 away from the movable ball 24 is connected to the inside of the square groove 25.

[0038] In this embodiment, when it is necessary to clean the inside of the pipe at multiple angles, the locking plate 12 is moved downward by driving the electric lifting rod 7. During the movement, the locking plate 12 causes the locking bar 21 to abut against the locking groove 22, thereby positioning the locking plate 12. The cross section of the transmission plate 11 is sloped, so that the water flow direction of the cleaning nozzle 19 deviates from the central axis of the cleaning unit 4.

[0039] Then, the driving motor 9 is started. During the rotation process, the driving motor 9 drives the hollow rod 10 to start rotating through the conveyor belt 17. During the rotation process, the hollow rod 10 drives the locking plate 12 to start rotating through the transmission plate 11. The locking plate 12 is in an inclined state at this time. During the process of rotating along the central axis of the cleaning unit 4, the water flow sprayed by the cleaning nozzle 19 can be deviated from the central axis of the cleaning unit 4, thereby increasing the cleaning efficiency of the pipeline;

[0040] When multi-angle cleaning is not needed, the electric lifting rod 7 is driven again, and the electric lifting rod 7 drives the positioning plate 8 to move upward. The positioning plate 8 drives the locking plate 12 to move upward through the support rod 15, so that the locking bar 21 is separated from the locking groove 22. Since the four springs 26 are symmetrically arranged, when the locking bar 21 is separated from the locking groove 22, the locking plate 12 and the support rod 15 remain in a vertical state, which facilitates the subsequent clamping block 20 to be clamped with the inside of the positioning groove 18.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
