Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment, and particularly to a cleaning device for attachments of an underwater cylindrical detector. Background Art

[0002] The ocean area accounts for 71% of the earth's surface area. There are rich resources hidden in the ocean floor. The research, development, and utilization of the ocean are inseparable from ocean measurement instruments and ocean engineering equipment. In many cases in the fields of underwater detection of biological and environmental resources, detection of the working state of underwater engineering equipment, underwater communication, etc., underwater equipment is required to perform long-term underwater operations in the operation area. Underwater detection equipment has developed vigorously in the past 20 years. Underwater engineering equipment has shown a diversified development trend, with more and more perfect functions and greatly improved original performance. Detection instruments are developing towards miniaturization and light weight, and reliability has also been greatly improved.

[0003] In the related art, the Chinese invention patent with the publication number CN209319670U discloses a combined debugging platform for a cylindrical underwater detector, including a front support platform trolley and a rear support platform trolley. The structure of the front support platform trolley is the same as that of the rear support platform trolley. The front support platform trolley and the rear support platform trolley are connected together by a lead screw connection mechanism. On the top surface of the front support platform trolley, a left support roller group and a right support roller group are respectively arranged. An annular convex clamping ring embedding groove is arranged between the left support roller group and the right support roller group. An annular clamping hoop composed of a lower half annular clamping hoop and an upper half annular clamping hoop is movably arranged on the left support roller group and the right support roller group. An annular convex clamping ring arranged at the center of the outer ring of the annular clamping hoop is clamped in the annular convex clamping ring embedding groove. Radial jackscrews are arranged at equal intervals in the arc of the annular clamping hoop. A jacking block is arranged at the inner end of the radial jackscrew in the annular clamping hoop. A cylindrical product to be debugged is clamped in the annular clamping hoop.

[0004] In view of the above related art, after the cylindrical detector is put into the water for detection, long-term underwater work will cause a large amount of microorganisms, aquatic organisms or sediment to adhere to the outer surface of the cylindrical detector, increasing the weight of the detector and the resistance during forward movement. Therefore, after the detection task is completed, it is usually necessary to clean the outer surface of the detector. The existing cleaning method is that the staff holds a high-pressure water gun to wash the surface of the detector. After washing one side, the detector is rolled over to the other side and the other side is continued to be washed. This cleaning process increases the work intensity of the staff and the cleaning efficiency is low. Summary of the Invention

[0005] In order to reduce the work intensity of the staff and improve the cleaning efficiency of the cylindrical detector, the present application provides a cleaning device for attachments of an underwater cylindrical detector.

[0006] The underwater cylindrical detector attachment cleaning device provided by this application adopts the following technical solution:

[0007] An underwater cylindrical detector attachment cleaning device includes a support frame for vertically supporting the detector. The support frame includes a bottom plate fixed to the ground, a vertical support rod fixed to the bottom plate, and a top frame fixed to the top of the vertical support rod. A driving plate is rotatably arranged on the bottom plate. The detector is vertically inserted between the top frame and the bottom plate. A driving groove is formed at the end of the detector. The driving plate is inserted into the driving groove. A rotating mechanism for driving the driving plate to rotate is arranged on the bottom plate. A first high-pressure nozzle is installed on the vertical support rod. A driving mechanism for driving the first high-pressure nozzle to reciprocate vertically is arranged on the vertical support rod. An anti-tipping frame for preventing the detector from tipping over is arranged on the top frame.

[0008] By adopting the above technical solution, the detector is slowly lowered through the top frame so that the driving plate is inserted into the driving groove. The driving mechanism can drive the first high-pressure nozzle to reciprocate vertically, enabling the first high-pressure nozzle to clean one side of the outer peripheral surface of the detector. When the rotating mechanism drives the driving plate to rotate, under the protection of the anti-tipping frame, the driving plate can drive the detector to rotate stably, making the un-cleaned part of the detector face the first high-pressure nozzle. Repeating this process enables the first high-pressure nozzle to automatically clean the entire outer peripheral surface of the detector, reducing the work intensity of the staff and improving the cleaning efficiency of the cylindrical detector.

[0009] Preferably, the rotating mechanism includes a rotating seat rotatably arranged on the top surface of the bottom plate. The driving plate is fixed to the rotating seat. A first gear is fixedly connected to the rotating seat. A first motor is fixedly connected to the bottom plate. A second gear capable of meshing with the first gear is fixedly connected to the output shaft of the first motor.

[0010] By adopting the above technical solution, when the first motor is driven, the first motor rotates slowly, and the first gear meshes with the second gear, enabling the first motor to drive the driving plate to rotate. When the electrical circuit of the first motor is disconnected, the rotation of the driving plate can automatically stop, enabling the driving plate to drive the detector to rotate a certain angle, making the un-cleaned side of the detector face the first high-pressure nozzle.

[0011] Preferably, the driving mechanism includes a mounting seat fixedly connected to the vertical support rod. A reciprocating screw is rotatably arranged on the mounting seat. A nut seat is fitted and mounted on the reciprocating screw. A guide rail is fixedly connected to the vertical support rod. A guide block is fixedly connected to the nut seat. The guide block is slidably arranged on the guide rail. A second motor is fixedly connected to the bottom plate. The output shaft of the second motor is coaxially and fixedly connected to the reciprocating screw. The first high-pressure nozzle is fixedly installed on the nut seat.

[0012] By adopting the above technical solution, the guide block is slidably arranged on the guide rail, and at the same time, the guide block is fixed to the nut seat. When the second motor is started, the second motor can drive the reciprocating screw to rotate, causing the nut seat to move vertically back and forth, so that the nut seat drives the first high-pressure nozzle to move vertically back and forth on one side of the detector, thereby cleaning one side of the detector.

[0013] Preferably, a first control mechanism is arranged on the bottom plate. The first control mechanism includes a first fixed seat fixedly connected to the bottom plate. A first sliding groove is formed on the top surface of the first fixed seat. A first control block is slidably arranged in the first sliding groove. A first spring for preventing the first control block from sliding into the first sliding groove is slidably arranged in the first sliding groove. A first fixed contact is embedded on the inner wall of the first sliding groove. A first moving contact capable of contacting the first fixed contact is embedded on the first control block. The first fixed contact is in a vertical strip shape. The first fixed contact and the first moving contact are electrically connected to the electrical circuit of the first motor. A pressing plate for pressing the first control block downward is arranged on the nut seat.

[0014] By adopting the above technical solution, while the nut seat drives the first high-pressure nozzle to move vertically, when the first high-pressure nozzle moves downward to the lower part of the detector, the pressing plate can press the first control block into the first sliding groove, making the first moving contact contact the first fixed contact, so that the electrical circuit of the first motor is turned on. Furthermore, when the first high-pressure nozzle moves to the lower part of the detector, the first motor can drive the detector to automatically rotate a certain angle. And after the nut seat drives the first high-pressure nozzle to move upward, the first control block moves upward under the elastic force of the first spring, causing the first moving contact to separate from the first fixed contact. Thus, when the first high-pressure nozzle moves back and forth again, it can wash the side of the detector that has not been cleaned.

[0015] Preferably, a second control mechanism is provided on one side of the first gear. The second control mechanism includes a second fixed seat fixedly connected to the bottom plate. A second sliding groove is formed on the side surface of the second fixed seat. A second control block that can abut against the outer side surface of the first gear is arranged in the second sliding groove. The second control block is slidably arranged in the second sliding groove. An inclined surface for abutting against the teeth of the first gear is provided on the second control block. A second spring for preventing the second control block from sliding into the second sliding groove is arranged in the second sliding groove. A second fixed contact is embedded on the inner wall of the second sliding groove. A second moving contact that can abut against the second fixed contact is embedded on the second control block. The second moving contact and the second fixed contact are electrically connected to the electrical circuit of the second motor.

[0016] By adopting the above technical solution, during the process of the nut seat driving the first high-pressure nozzle to move vertically, the electrical circuit of the first motor is in an open state. At this time, the first gear is in a stationary state. The second moving contact on the second control block contacts the second fixed contact under the push of one of the teeth of the first gear, enabling the second motor to start. When the first high-pressure nozzle moves to the lower part of the detector, the pressing plate presses the first control block downward, starting the first motor. During the process of the first motor driving the first gear to slowly rotate through the first gear, when the second control block faces the tooth pitch of the first gear, the second control block slides out of the second sliding groove under the elastic force of the second spring, disconnecting the electrical circuit of the second motor. As a result, the high-pressure water gun automatically stays briefly at the lower part of the detector. After the detector finishes rotating, an adjacent tooth on the first gear can push the second control block back into the second sliding groove again, causing the second moving contact to resume contact with the second fixed contact. Consequently, the second motor automatically drives the first high-pressure nozzle to move vertically after the first gear rotates by an angle of one tooth, automatically cleaning the side of the detector that has not been cleaned.

[0017] Preferably, a mounting bracket is fixedly connected to the base plate, a second high-pressure nozzle facing the lower round head of the detector is fixedly installed on the mounting bracket, the second high-pressure nozzle is connected to a connecting pipe, a booster pump is arranged on the connecting pipe, the booster pump includes a handle switch for controlling the start and stop of the booster pump, a third control mechanism is arranged on the base plate, the third control mechanism includes a vertical shaft rotatably arranged on the base plate, a third gear is fixedly connected to the vertical shaft, a fourth gear is fixedly connected to the output shaft of the second motor, the third gear and the fourth gear are connected by a reducer, a vertical plate is arranged on the side of the booster pump away from the vertical axis, a third spring is fixedly connected to the side of the vertical plate close to the booster pump, an end of the third spring away from the vertical plate is fixedly connected to a resistance block that resists the handle of the handle switch, and a cam for pushing the handle toward the side close to the vertical plate is fixedly connected to the vertical shaft.

[0018] By adopting the above technical scheme, when the first high-pressure nozzle flushes the surrounding side of the detector, the water flow sprayed by the first high-pressure nozzle can remain perpendicular to the outer peripheral surface of the detector, thereby achieving a better cleaning effect. However, the round head of the detector is at an angle to the water flow sprayed by the first high-pressure nozzle, making it difficult to clean the round head. Therefore, when the detector rotates, the handle of the handle-type switch is in an open state pushed by the cam to the side close to the vertical plate. At this time, the second high-pressure nozzle can automatically flush the round head at the lower part of the current detector, and when the detector stops rotating, the second motor can drive the cam to continue rotating through the reducer to disengage the handle. At this time, the handle swings to the side close to the vertical axis under the elastic force of the third spring, so that the booster pump is turned off and the flushing of the round head of the detector is suspended, thereby avoiding the situation where the second high-pressure water gun continues to flush the round head after the detector stops rotating, thereby reducing the possibility of damage to the outer surface coating of the detector due to high-pressure water flow.

[0019] Preferably, a telescopic rod is provided inside the third spring, one end of the telescopic rod is fixedly connected to the vertical plate, and the other end of the telescopic rod is fixedly connected to the abutment block.

[0020] Preferably, the anti-fall frame includes two connecting rods fixed vertically to each other, the connecting rods are detachably connected to the top frame, a plurality of blocking rods are arranged around the top of the detector, the detector is located between the plurality of blocking rods, and the blocking rods are fixedly connected to the connecting rods.

[0021] By adopting the above technical solution, the baffle rod is fixedly connected to the connecting rod, the connecting rod is detachably connected to the top frame, and the detector is located between multiple baffle rods. Therefore, the baffle rod can prevent the detector from tipping over and enable the detector to rotate, so that the first high-pressure nozzle can flush the detector more stably.

[0022] Preferably, there are four blocking rods arranged on the periphery of the detector, and the four blocking rods are evenly distributed on the periphery of the detector along the circumferential direction of the detector.

[0023] Preferably, the connecting rod and the top frame are connected to each other by bolts.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Slowly lower the detector through the top frame so that the driving plate is inserted into the driving groove. The driving mechanism can drive the first high-pressure nozzle to move vertically back and forth, enabling the first high-pressure nozzle to clean one side of the outer peripheral surface of the detector. When the rotating mechanism drives the driving plate to rotate, under the protection of the anti-toppling frame, the driving plate can drive the detector to rotate stably, making the un-cleaned part of the detector face the first high-pressure nozzle. In this way, the first high-pressure nozzle can automatically clean the entire outer peripheral surface of the detector, reducing the working intensity of the staff and improving the cleaning efficiency of the cylindrical detector;

[0026] 2. During the process of the nut seat driving the first high-pressure nozzle to move vertically, the electrical circuit of the first motor is in an open state. At this time, the first gear is in a stationary state. The second moving contact on the second control block is pushed by one of the teeth of the first gear to contact the second fixed contact, enabling the second motor to be in a starting state. When the first high-pressure nozzle moves to the lower part of the detector, the pressing plate presses the first control block downward, starting the first motor. During the process of the first motor driving the first gear to rotate slowly through the second gear, when the second control block faces the tooth pitch of the first gear, the second control block slides out of the second sliding groove under the elastic force of the second spring, disconnecting the electrical circuit of the second motor. As a result, the high-pressure water gun automatically stays briefly at the lower part of the detector. After the detector rotates, an adjacent tooth of the first gear can push the second control block back into the second sliding groove again, causing the second moving contact to resume contact with the second fixed contact. Thus, the second motor automatically drives the first high-pressure nozzle to move vertically after the first gear rotates by the angle of one tooth, automatically cleaning the un-cleaned side of the detector;

[0027] 3. When the first high-pressure nozzle flushes the periphery of the detector, the water flow ejected by the first high-pressure nozzle can be perpendicular to the outer peripheral surface of the detector, thus having a good cleaning effect. However, the round head of the detector forms an angle with the water flow ejected by the first high-pressure nozzle, making it difficult to clean the round head thoroughly. Therefore, when the detector rotates, the handle of the handle-type switch is in the open state where it is pushed by the cam towards the side close to the vertical plate. At this time, the second high-pressure nozzle can automatically flush the round head at the lower part of the current detector. And when the detector stops rotating, the second motor can drive the cam to continue rotating through the speed reducer, causing the cam to disengage from the handle. At this time, under the elastic force of the third spring, the handle swings towards the side close to the vertical shaft, closing the booster pump and pausing the flushing of the round head of the detector, thus avoiding the situation where the second high-pressure water gun continuously flushes the round head after the detector stops rotating, and further reducing the possibility of damage to the outer surface coating of the detector caused by high-pressure water flow.

A driving plate 15 is fixedly connected to the top surface of the rotating base 51. A cylindrical detector 100 is arranged on the support frame 1. The detector 100 passes through the top frame 13 from top to bottom. During this process, the round head 101 of the detector 100 is vertically downward. A driving groove is opened at the bottommost part of the round head 101 of the detector 100. When the detector 100 is installed in place, the detector 100 is located between the top frame 13 and the bottom plate 11, and the driving plate 15 is inserted into the driving groove.

[0037] Referring to Figure 1 As shown in the figure, the anti-toppling frame 14 includes a connecting rod 141 and a blocking rod 142. There are two connecting rods 141.

The second motor 66 is fixedly connected to the top surface of the bottom plate 11, and the output shaft of the second motor 66 is coaxially welded and fixed to the reciprocating screw 62.

[0040] Referring to Figure 1 and Figure 2As shown, the guide rail 64 is fixedly connected to the vertical support rod 12 where the mounting seat 61 is located. The length direction of the guide rail 64 is parallel to the length direction of the vertical support rod 12.

[0041] Referring to Figure 1 and Figure 3 As shown, the first control mechanism 7 includes a first fixed seat 71, a first control block 72, a first spring 73, a first fixed contact 74 and a first moving contact 75. The first fixed seat 71 is fixedly connected to the top surface of the bottom plate 11. The first fixed seat 71 is located on one side of the first motor 53. A first sliding groove 711 is formed on the top surface of the first fixed seat 71, and the first control block 72 is vertically slidably arranged in the first sliding groove 711.

[0042] Referring to Figure 1 and Figure 3 As shown, the first spring 73 is arranged in the first sliding groove 711. One end of the first spring 73 is fixedly connected to the bottom wall of the first sliding groove 711, and the other end of the first spring 73 is fixedly connected to the bottom surface of the first control block 72. The first spring 73 prevents the first control block 72 from sliding downward. The first fixed contact 74 is in a vertical strip shape, the first fixed contact 74 is embedded in the inner wall of the first sliding groove 711, the first moving contact 75 is embedded in the first control block 72. When the first control block 72 slides downward, the first moving contact 75 can contact the first fixed contact 74, and the first fixed contact 74 and the first moving contact 75 are electrically connected to the electrical circuit of the first motor 53.

[0043] Referring to Figure 1 and Figure 3 As shown, the pressing plate 631 is fixedly connected to the nut seat 63. When the nut seat 63 moves downward to the lower part of the reciprocating screw rod 62, the pressing plate 631 can press the first control block 72 into the first sliding groove 711, so that the first moving contact 75 can contact the first fixed contact 74, making the electrical circuit of the first motor 53 be automatically turned on, so that the first motor 53 automatically drives the detector 100 to rotate a certain angle when the first high-pressure nozzle 2 moves to the lower part of the detector 100. And after the nut seat 63 moves upward, under the elastic force of the first spring 73, the first control block 72 is pushed upward, so that the first high-pressure nozzle 2 automatically flushes the unwashed side of the detector 100.

[0044] Referring to Figure 1 and Figure 4As shown, the second control mechanism 8 includes a second fixed seat 81, a second control block 82, a second spring 83, a second fixed contact 84, and a second moving contact 85. The second fixed seat 81 is fixedly connected to the top surface of the bottom plate 11. The second fixed seat 81 is located on one side of the rotating seat 51. A second sliding groove 811 is formed on the side surface of the second fixed seat 81 close to the rotating seat 51. The second control block 82 is horizontally slidably disposed in the second sliding groove 811.

[0045] Referring to Figure 1 and Figure 4 As shown, the second spring 83 is disposed in the second sliding groove 811. One end of the second spring 83 is fixedly connected to the side wall of the second sliding groove 811 away from the rotating seat 51, and the other end of the second spring 83 is fixedly connected to the side surface of the second control block 82 away from the rotating seat 51. The second spring 83 impedes the second control block 82 from sliding into the second sliding groove 811.

The second moving contact 85 and the second fixed contact 84 are electrically connected to the electrical circuit of the second motor 66.

[0047] Referring to Figure 1 and Figure 4 As shown, a slope 821 is provided on the second control block 82. During the rotation of the first gear 52, the slope 821 can abut against the teeth of the first gear 52. And under the action of the slope 821, the teeth of the first gear 52 can push the second control block 82 into the second sliding groove 811, so that the second moving contact 85 contacts the second fixed contact 84. During the rotation of the first gear 52, when the distance between the teeth of the first gear 52 faces the second control block 82, the second spring 83 can push the second control block 82 in the direction close to the rotating seat 51, so that the second moving contact 85 is separated from the second fixed contact 84, causing the first high-pressure nozzle 2 to automatically stay briefly below the detector 100 and wait for the detector 100 to rotate a certain angle.

[0048] Referring to Figure 1 and Figure 4As shown, after a tooth on the first gear 52 pushes the second control block 82 into the second sliding groove 811 through the inclined surface 821, the second moving contact piece 85 contacts the second fixed contact piece 84 again, causing the second motor 66 to start automatically. At this time, the nut seat 63 drives the first high-pressure nozzle 2 and the pressing plate 631 to move upward, so that the first high-pressure nozzle 2 vertically reciprocates to wash the unwashed side of the detector 100. At the same time, the pressing plate 631 automatically disengages from the first control block 72, causing the first motor 53 to stop automatically, so that the rotating seat 51 stops rotating automatically, enabling the first high-pressure nozzle 2 to wash the outer side of the detector 100 more stably.

[0049] Refer to Figure 1 、 Figure 3 and Figure 4 As shown, in addition, the first fixed contact piece 74 is strip-shaped. When the first moving contact piece 75 contacts the top of the first fixed contact piece 74, the first motor 53 drives the first gear 52 to rotate slowly through the second gear 54. At the initial stage of the rotation of the first gear 52, the side of the first gear 52 away from the axis line abuts against the side of the second control block 82 close to the rotating seat 51.

[0050] Refer to Figure 2 、 Figure 3 and Figure 4 As shown, when the second control block 82 disengages from the current tooth, the second motor 66 stops, and the first moving contact piece 75 returns to the upper part of the first fixed contact piece 74. When an adjacent tooth on the first gear 52 pushes the second control block 82 into the second sliding groove 811 through the inclined surface 821, the second moving contact piece 85 contacts the second fixed contact piece 84 again, and the nut seat 63 drives the first high-pressure nozzle 2 to move upward.

[0051] Refer to Figure 1 and Figure 2 As shown, an installation frame 3 is fixedly connected to the bottom plate 11, and the second high-pressure nozzle 4 is fixedly installed on the installation frame 3. The second high-pressure nozzle 4 is located below the side of the detector 100, and the second high-pressure nozzle 4 faces the lower round head 101 of the detector 100. A connecting pipe 41 is connected to the second high-pressure nozzle 4, a booster pump 42 is arranged on the connecting pipe 41, and a handle switch 43 is arranged on the booster pump 42. The handle switch 43 is fixedly connected to the bottom plate 11, and this handle switch 43 is used to control its start and stop.

[0052] Refer to Figure 1 and Figure 2As shown, the third control mechanism 9 includes a vertical shaft 91, a third gear 92, a fourth gear 93, a speed reducer 94, a vertical plate 95, a third spring 96, a telescopic rod 97, a cam 98 and a contact block 99. The vertical shaft 91 is rotatably arranged on the bottom plate 11, the vertical shaft 91 is vertically arranged, the third gear 92 is fixedly connected to the vertical shaft 91, the fourth gear 93 is fixedly connected to the output shaft of the second motor 66, the speed reducer 94 is fixedly connected to the bottom plate 11, and the third gear 92 and the fourth gear 93 are connected through the speed reducer 94.

[0053] Referring to Figure 1 and Figure 2 As shown, the vertical plate 95 is fixedly connected to the side of the booster pump 42 away from the vertical shaft 91. One end of the third spring 96 is fixedly connected to the side of the vertical plate 95 close to the booster pump 42, the contact block 99 is fixedly connected to the end of the third spring 96 away from the vertical plate 95, the telescopic rod 97 is arranged between the vertical plate 95 and the contact block 99, the telescopic rod 97 is horizontally arranged inside the third spring 96, and both ends of the telescopic rod 97 are fixedly connected to the vertical plate 95 and the contact block 99 respectively. The cam 98 is fixedly connected to the vertical shaft 91. When the rotating seat 51 drives the detector 100 to rotate, the fourth gear 93 drives the third gear 92 to rotate through the speed reducer 94, so that the cam 98 can contact the handle of the handle type switch 43 and push the handle towards the direction close to the vertical plate 95, so that the booster pump 42 is in the open state. When the rotating seat 51 stops rotating, the third spring 96 can push the handle of the handle type switch 43 towards the side close to the cam 98 through the contact block 99, so that the booster pump 42 is in the closed state.

[0054] The implementation principle of the underwater cylindrical detector attachment cleaning device in the embodiment of the present application is as follows: The detector 100 is slowly lowered through the top frame 13, so that the driving plate 15 is inserted into the driving groove. When the first high-pressure nozzle 2 moves downward to the lower part of the detector 100, the pressing plate 631 can press the first control block 72 into the first sliding groove 711, so that the first moving contact 75 contacts the first fixed contact 74, thereby conducting the electrical circuit of the first motor 53. Then, when the first high-pressure nozzle 2 moves to the lower part of the detector 100, the first motor 53 can drive the detector 100 to automatically rotate a certain angle. After the nut seat 63 drives the first high-pressure nozzle 2 to move upward, the first control block 72 moves upward under the elastic force of the first spring 73, so that the first moving contact 75 is separated from the first fixed contact 74. Thus, when the first high-pressure nozzle 2 reciprocates again, it can wash the side of the detector 100 that has not been cleaned.

[0055] During the process of the nut seat 63 driving the first high-pressure nozzle 2 to move vertically, the electrical circuit of the first motor 53 is in an open state. At this time, the first gear 52 is in a stationary state. The second moving contact 85 on the second control block 82 contacts the second fixed contact 84 under the push of one of the teeth of the first gear 52, causing the second motor 66 to start. When the first high-pressure nozzle 2 moves to the lower part of the detector 100, the pressing plate 631 presses the first control block 72 downward, starting the first motor 53. During the process of the first motor 53 driving the first gear 52 to rotate slowly through the first gear 52, when the second control block 82 faces the tooth pitch of the first gear 52, the second control block 82 slides out of the second sliding groove 811 under the elastic force of the second spring 83, disconnecting the electrical circuit of the second motor 66. As a result, the high-pressure water gun automatically stays briefly below the detector 100. After the detector 100 finishes rotating, an adjacent tooth on the first gear 52 can push the second control block 82 back into the second sliding groove 811 again, causing the second moving contact 85 to resume contact with the second fixed contact 84. Consequently, the second motor 66 automatically drives the first high-pressure nozzle 2 to move vertically after the first gear 52 rotates by the angle of one tooth, automatically cleaning the side of the detector 100 that has not been cleaned. Repeating this process enables the first high-pressure nozzle 2 to automatically clean the entire outer peripheral surface of the detector 100, reducing the work intensity of the staff and improving the cleaning efficiency of the cylindrical detector 100.

[0056] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
