DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the technical scheme of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. The same reference signs in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0019] Reference Figure 1 The embodiments of the present application propose an automatic maintenance device for a pier, comprising a pier body 1, the upper end of the pier body 1 being fixedly connected with a support 3 through bolts, the inner side of the support 3 being provided with a control cabinet 2, the support 3 being provided with a moving module 4, and the moving module 4 being provided with a moving spraying module 5.

[0020] The moving spraying module 5 is controlled to move through the control cabinet 2, and the moving spraying module 5 cooperates with the moving module 4 to perform spraying maintenance on the pier body 1, replacing manual watering maintenance, saving time and effort, and greatly improving the maintenance efficiency.

[0021] Reference Figures 1-12The moving module 4 comprises a pair of curved slides 41, a pair of straight slides 42 and a moving platform 43. The pair of curved slides 41 and the pair of straight slides 42 are fixed to the support 3. The pair of curved slides 41 are connected by the pair of straight slides 42. The moving platform 43 can move on the curved slides 41 and the straight slides 42. The moving platform 43 has an assembly chamber 461 in the middle of the lower wall. A steel ball 462 is movably embedded in the assembly chamber 461. The lower end of the steel ball 462 extends out of the assembly chamber 461 and is in contact with the straight slide 42. During the movement of the moving platform 43 on the straight slide 42, the steel ball 462 is in contact with the upper wall of the straight slide 42. The steel ball 462 is arranged to leave a gap between the moving platform 43 and the straight slide 42, so as to prevent the straight slide 42 from blocking the discharge holes A4102 and B4104, and to ensure the successful discharge of the mineral oil and air. The moving module 4 further comprises a fluid storage chamber A4101 provided in the moving platform 43, a discharge hole A4102 provided in the middle of the lower wall of the moving platform 43, a connecting hole A4103 connecting the discharge hole A4102 and the fluid storage chamber A4101, an assembly shell 44 fixed to the side wall of the moving platform 43, and a box 45 fixed to the side wall of the assembly shell 44. The box 45 is filled with mineral oil.

[0022] The moving module 4 further comprises a traction unit arranged in the assembly shell 44. The traction unit comprises a small motor 471 arranged in the assembly shell 44, a rotating rod 472 rotatably connected to the assembly shell 44, a rotating disc 473 fixed to the rotating rod 472, and a linkage 474 connecting the rotating rod 472 and the rotating part of the small motor 471. The linkage 474 comprises a sprocket A fixed to the rotating rod 472 and a sprocket B fixed to the rotating part of the small motor 471. The sprocket A and the sprocket B are connected by a chain. The small motor 471 can drive the rotating rod 472 to rotate through the linkage 474. The rotating rod 472 can drive the rotating disc 473 to rotate when the rotating rod 472 rotates. The rotating part of the small motor 471 extends into the box 45 and is fixed to a turning blade 411. The small motor 471 can drive the turning blade 411 to rotate when the small motor 471 works. The turning blade 411 can turn the mineral oil in the box 45 to prevent the raw materials in the mineral oil from depositing, thereby ensuring the maintenance function of the mineral oil on the straight slide 42.

[0023] The moving module 4 further comprises a suction unit, which is arranged in the assembly shell 44 and cooperates with the traction unit to convey the mineral oil to the changing table 43. The suction unit comprises a leakproof pipe 481, which is fixed to the assembly shell 44 through a connecting column; a through hole 482, which is reserved on one side of the leakproof pipe 481; a rubber sheet 483, which is fixed to the through hole 482; a magnet A 484, which is fixed to the upper wall of the rotating disc 473; a magnet B 485, which is fixed to the lower wall of the rubber sheet 483, the magnet A 484 is directly below the magnet B 485 and can be attracted to each other; a pair of channels A 486, one side of each of the channels A 486 is connected with the leakproof pipe 481, one side of one of the channels A 486 is connected with the box 45, and one side of the other of the channels A 486 is connected with the fluid storage chamber A 4101; a pair of check valves 487, each of which is arranged on one of the channels A 486. During the rotation of the rotating disc 473, the magnet A 484 rotates with it. During the rotation of the magnet A 484, the magnet A 484 rotates intermittently to face the magnet B 485.

[0024] When the magnet A 484 faces the magnet B 485, the magnet A 484 and the magnet B 485 are attracted to each other, the magnet B 485 is connected with the magnet A 484, and the magnet B 485 changes the shape of the rubber sheet 483, which arches outward from the leakproof pipe 481. At this moment, the volume of the chamber composed of the leakproof pipe 481 and the rubber sheet 483 becomes larger. When the magnet A 484 and the magnet B 485 are misaligned with each other, the rubber sheet 483 returns to its original state under its own deformation force, and the volume of the chamber composed of the leakproof pipe 481 and the rubber sheet 483 becomes smaller. When the volume of the chamber composed of the leakproof pipe 481 and the rubber sheet 483 becomes larger, the leakproof pipe 481 can perform the suction work; when the volume of the chamber composed of the leakproof pipe 481 and the rubber sheet 483 becomes smaller, the leakproof pipe 481 can perform the discharge work. In addition, because the flow directions of the two check valves 487 are opposite to each other, one of the check valves 487 restricts the fluid to flow only into the leakproof pipe 481, and the other of the check valves 487 restricts the fluid to flow only out of the leakproof pipe 481. Therefore, with the rotation of the magnet A 484, the leakproof pipe 481 can continuously suck the mineral oil in the box 45 and convey it to the fluid storage chamber A 4101, so that the mineral oil is discharged to the straight slide 42 through the discharge hole A 4102. During this period, the changing table 43 changes on the straight slide 42, and the mineral oil is evenly discharged to the wall surface of the straight slide 42 through the discharge hole A 4102, achieving self-coating of the mineral oil and then achieving the purpose of self-maintenance.

[0025] The fluid temporary storage chamber B4103 is reserved in the variable platform 43, and the discharge hole B4104 is reserved at the lower end of the variable platform 43, the discharge hole B4104 and the fluid temporary storage chamber B4103 are communicated with each other, and the air feeding unit is arranged in the assembly shell 44, the air feeding unit comprises: an air feeding pipe 491 fixedly connected in the assembly shell 44; a plurality of air inlet grooves 492 reserved on the air feeding pipe 491; an air feeding piece 493 fixedly connected to the rotating part of the small motor 471, and arranged in the air feeding pipe 491; and a channel B494 communicated with the air feeding pipe 491 on one side and communicated with the fluid temporary storage chamber B4103 on the other side. When the small motor 471 works, the air feeding piece 493 can be driven to rotate, and during the rotation, the air feeding piece 493 feeds the external airflow into the plurality of air inlet grooves 492, and then the rotating air feeding piece 493 can convey the airflow into the fluid temporary storage chamber B4103 through the channel B494, so that the airflow is discharged to the outer wall of the straight slide 42 through the discharge hole B4104; in this case, the airflow can drive the mineral oil on the straight slide 42, so that the mineral oil can be uniformly varied along the outer wall of the straight slide 42, and the mineral oil can be uniformly coated on the outer wall of the straight slide 42, so that the straight slide 42 is self-coated with the mineral oil, and the self-maintenance purpose is achieved.

[0026] The recovery unit is arranged on both sides of the straight slide 42, and the recovery unit comprises: a side block 4121 fixedly connected to the side wall of the straight slide 42, the side block 4121 is in the shape of a right-angled folding ruler and is a hollow structure; a recovery port 4122 reserved at the upper end of the side block 4121; a plurality of communication ports A 4123 reserved on the recovery port 4122, each communication port A 4123 being communicated with the inside of the side block 4121; a variable piece 4124 movably arranged on the surface of the recovery port 4122, the side wall of the variable piece 4124 being in contact with the surface of the recovery port 4122, gaps being left between the side walls of the variable piece 4124 and the surface of the recovery port 4122, and the lower wall of the variable piece 4124 being in contact with the surface of the recovery port 4122, the side block 4121 and the variable piece 4124 being made of magnetite; a plurality of communication ports B 4125 reserved on the variable piece 4124; and an elastic member 4126 connected to the side block 4121 on one side and connected to the variable piece 4124 on the other side. The mineral oil sliding down along the outer wall of the straight slide 42 falls into the side block 4121 through the combined plurality of communication ports A 4123 and the plurality of communication ports B 4125, so that the excess mineral oil can be recovered, and the maintenance cost is reduced.

[0027] The edge block 4121 is provided with a control unit, which comprises a rotating pipe 4131, a screw rod 4132, and a convex disc 4133. The rotating pipe 4131 is screwed to one side of the recovery port 4122. The screw rod 4132 is fixedly connected to the rotating pipe 4131. The convex disc 4133 is fixedly connected to the outer circumferential wall of the rotating pipe 4131, and the rotating pipe 4131 is located at one side of the center of the convex disc 4133. One side of the convex disc 4133 faces the variable piece 4124. Before filling the mineral oil, the user rotates the screw rod 4132 by using a tool, and then the rotating pipe 4131 is rotated by the screw rod 4132. When the rotating pipe 4131 rotates, the convex disc 4133 can be rotated. When the convex disc 4133 rotates, the variable piece 4124 can be pressed, so that the variable piece 4124 is deformed in the recovery port 4122. When one side of the variable piece 4124, which is far away from the convex disc 4133, is rotated to be attached to one side of the recovery port 4122, a plurality of through holes B 4125 on the variable piece 4124 are respectively connected to a plurality of through holes A 4123 on the recovery port 4122.

[0028] The moving module 4 further comprises a supporting seat 414 fixedly connected to the upper end of the variable table 43. The supporting seat 414 is provided with a battery 415 at the upper end. One side of the battery 415 is provided with a controller 416. The battery 415 and the controller 416 are electrically connected to the small motor 471. The battery 415 and the controller 416 are both prior art, and will not be described in detail here.

[0029] The small motor 471 is controlled by the controller 416 to act, and then when the variable table 43 is deformed to the straight slide 42, self-maintenance is realized.

[0030] When the maintenance is performed on the straight slide 42, the power supply of the small motor 471 is turned on, and the small motor 471 rotates, and the rotating rod 472 is dragged to rotate through the linkage 474, and the rotating disk 473 is dragged to rotate when the rotating rod 472 rotates, and the magnet A 484 rotates with the rotating disk 473 during the rotation, and the magnet A 484 rotates to face the magnet B 485 intermittently during the rotation of the magnet A 484; when the magnet A 484 faces the magnet B 485, the magnet A 484 and the magnet B 485 are attracted to each other, the magnet B 485 is connected to the magnet A 484, and the magnet B 485 changes the shape of the rubber sheet 483, and the rubber sheet 483 arches outwardly from the outer side of the leak-proof pipe 481, and the volume of the chamber formed by the leak-proof pipe 481 and the rubber sheet 483 increases at this moment; when the magnet A 484 and the magnet B 485 are misaligned with each other, the rubber sheet 483 returns to the original state under the deformation force of itself, and the volume of the chamber formed by the leak-proof pipe 481 and the rubber sheet 483 decreases; when the volume of the chamber formed by the leak-proof pipe 481 and the rubber sheet 483 increases, the leak-proof pipe 481 can perform the suction work; when the volume of the chamber formed by the leak-proof pipe 481 and the rubber sheet 483 decreases, the leak-proof pipe 481 can perform the discharge work; in addition, because the flow directions of the two check valves 487 are opposite to each other, one of the check valves 487 restricts the fluid to flow only into the leak-proof pipe 481, and the other check valve 487 restricts the fluid to flow only away from the leak-proof pipe 481, so the leak-proof pipe 481 can continuously suck the mineral oil in the box 45 and deliver the mineral oil to the fluid storage chamber A 4101 as the magnet A 484 rotates, and the mineral oil is discharged onto the straight slide 42 through the discharge hole A 4102, and during this period, the changing table 43 changes on the straight slide 42, and the mineral oil is evenly discharged onto the wall surface of the straight slide 42 through the discharge hole A 4102, so as to achieve the self-coating of the mineral oil, and then the self-maintenance is completed; When the small motor 471 works, it can drag the air delivery sheet 493 to rotate, and the air delivery sheet 493 sends the external airflow into the fluid storage chamber B 4103 through the air inlet groove 492 during the rotation, and then the rotating air delivery sheet 493 can deliver the airflow to the outer wall of the straight slide 42 through the channel B 494; in this case, the airflow can drive the mineral oil on the straight slide 42, and the mineral oil changes evenly along the outer wall of the straight slide 42, so that the mineral oil can be evenly coated on the outer wall of the straight slide 42, and the self-coating of the mineral oil on the straight slide 42 is realized, and then the self-maintenance is achieved; The recycling unit is arranged on both sides of the straight slide 42 and is used to recycle the mineral oil falling from the straight slide 42. Before filling the mineral oil, the user rotates the screw rod 4132 by using a tool, the rotating pipe 4131 is rotated by the screw rod 4132, the rotating pipe 4131 can rotate the convex disc 4133 when rotating, the convex disc 4133 can press the variable piece 4124 when rotating, the variable piece 4124 generates a change in the recycling port 4122, when the side of the variable piece 4124 far away from the convex disc 4133 rotates to the side of the recycling port 4122, the multiple connection openings B 4125 on the variable piece 4124 are connected with the multiple connection openings A 4123 on the recycling port 4122 respectively, in this case, the mineral oil falling along the outer wall of the straight slide 42 falls into the side block 4121 through the combined multiple connection openings A 4123 and multiple connection openings B 4125, this structure can recycle the excess mineral oil, and reduces the maintenance cost; in addition, the side wall of the side block 4121 is reserved with an oil discharge hole, the oil discharge hole is connected with the inside of the side block 4121, and the rubber block is clamped in the oil discharge hole; after the maintenance is completed, the user can pull out the rubber block from the oil discharge hole, and the recycled mineral oil in the side block 4121 can be discharged, and then the excess mineral oil can be repeatedly used. The variable piece 4124 is made of magnet material, the side block 4121 is made of magnet material, and the variable piece 4124 can be attracted to the side block 4121, this structure makes the variable piece 4124 only generate a change along the wall surface of the side block 4121 under the pressure of the convex disc 4133, and cannot be separated from the side block 4121, thereby ensuring the stability of the variable piece 4124 during the change; in addition, the elastic member 4126 is arranged between the variable piece 4124 and the side block 4121, after the maintenance is completed, the user rotates the screw rod 4132 by using a tool, the convex disc 4133 is rotated, until the convex disc 4133 cannot press the variable piece 4124, under the pressure of the convex disc 4133, the variable piece 4124 is reset under the cooperation of the elastic member 4126; when the variable piece 4124 returns to the original position, the multiple connection openings A 4123 and the multiple connection openings B 4125 are staggered with each other, at this moment, the variable piece 4124 can block the multiple connection openings A 4123, and the purpose of isolating the external environment is achieved, so as to prevent the mineral oil in the side block 4121 from weakening the maintenance function due to the external environment; The rotating part of the small motor 471 extends into the box 45 and is fixedly connected with the turning blade 411, the small motor 471 can rotate the turning blade 411 when rotating, the turning blade 411 can turn the mineral oil in the box 45 when rotating, which can prevent the raw materials in the mineral oil from depositing, and ensure the maintenance function of the mineral oil to the straight slide 42; The assembly chamber 461 is reserved on the variable table 43, and the steel ball 462 is movably embedded in the assembly chamber 461.

The cabinet 51 is provided with a servo motor 52, the rotating part of the servo motor 52 extends out of the cabinet 51 and is fixedly connected with a rotating shaft A53. The fixed plate 54 is fixedly connected with a steel pipe A55, and the fixed plate 54 is below the steel pipe B511. The steel pipe A55 is outside the moving track of the steel pipe B511. The steel pipe A55 is provided with an electromagnetic valve, which is electrically connected with the control cabinet 2. The upper end of the rotating shaft A53 is fixedly connected with a square tube A56. The upper end of the steel pipe A55 is connected with one side of the square tube A56 through a hose A57. The two sides of the hose A57 are respectively connected with the rotating connection of the steel pipe A55 and the square tube A56. The lower end of the steel pipe A55 is connected with an external water pipe. The other side of the square tube A56 is rotatably connected with a square tube B58. The square tube A56 and the square tube B58 are connected through a hose B59. The two sides of the hose B59 are respectively connected with the rotating connection of the square tube A56 and the square tube B58. The other side of the square tube B58 is rotatably connected with a rotating shaft B510 between the supporting seat 414. The upper end of the steel pipe B511 is connected with the square tube B58 through a hose C512. The two sides of the hose C512 are respectively connected with the rotating connection of the steel pipe B511 and the square tube B58. Two spray heads 513 are arranged on the steel pipe B511, and the spray heads 513 are arranged to face the pier body 1. The servo motor 52 and the control cabinet 2 are electrically connected with an external power supply. The servo motor 52 and the control cabinet 2 are prior art, which will not be described in detail here.

[0032] When the maintenance is performed on the pier body 1, the water pipe is connected with the steel pipe A55. The control cabinet 2 controls the electromagnetic valve to be opened and the servo motor 52 to be operated. The servo motor 52 drives the rotating shaft A53 to rotate, and then drives the variable table 43 and the supporting seat 414 to move through the square tube A56, the square tube B58 and the rotating shaft B510. Then the steel pipe B511 is driven to move, and a pair of spray heads 513 are driven to move through the moving steel pipe B511. During the movement of the variable table 43, water flows into the steel pipe B511 through the steel pipe A55, the hose A57, the square tube A56, the hose B59, the square tube B58 and the hose C512. The steel pipe B511 sprays water onto the pier body 1 through the spray heads 513, and then the self-maintenance of the pier body 1 is realized, replacing the artificial watering maintenance, saving time and effort, and greatly improving the maintenance efficiency.

[0033] In addition, it should be noted that when the variable platform 43 is on the curved slide 41 during self-maintenance, the servo motor 52 is in operation, at this time the small motor 471 is not in operation, when on the straight slide 42, the servo motor 52 and the small motor 471 are in operation, and after the maintenance of the straight slide 42, a little mineral oil is still attached to the inside of the variable platform 43 on the curved slide 41, which can still play a certain maintenance role for the curved slide 41 during the movement of the variable platform 43 on the curved slide 41, thereby realizing the maintenance of the entire slide and the variable platform 43, and ensuring the smoothness during use.

[0034] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
