DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0032] The embodiment of the present application discloses a translation wiper for a ship.

[0033] Reference Figure 1-Figure 3The present embodiment of a ship translation wiper comprises a base 1, a driving assembly 2, a bracket 3, a mounting assembly 4 and a wiper blade 5. The base 1 is detachably connected to a porthole 6. The bracket 3 is slidably connected to the base 1 along the length direction of the base 1, and the driving component 2 is used to drive the bracket 3 to move back and forth on the base 1. The mounting component 4 includes a fixed seat 41, a movable seat 42, a clamping member 43 and a plurality of first springs 44. The fixed seat 41 and the movable seat 42 are both L-shaped. One end of the fixed seat 41 is provided with a first slide groove 411, and one end of the movable seat 42 slides in the first slide groove 411. A plurality of first springs 44 are distributed along the length direction of the first slide groove 411. The two ends of the first spring 44 are respectively fixedly arranged on the bottom wall of the first slide groove 411 and on the movable seat 42. The other end of the fixed seat 41 and the movable seat 42 is a clamping end 45, and the two clamping ends 45 are arranged opposite to each other. The clamping member 43 is used to drive the two clamping ends 45 to clamp the scraper 5, and the first spring 44 is used to drive the two clamping ends 45 to separate from each other.

[0034] Reference Figure 1-Figure 3 When the scraper blade 5 is damaged, the operator loosens the clamping piece 43, and the first spring 44 automatically drives the movable seat 42 to move toward the side away from the fixed seat 41. The two clamping ends 45 loosen the scraper blade 5, and the operator can remove the scraper blade 5 and replace it with the scraper blade 5. The clamping piece 43 drives the two clamping ends 45 to re-clamp the scraper blade 5, which can facilitate the replacement of the scraper blade 5. During the entire replacement process, only the scraper blade 5 needs to be replaced, which can control the replacement cost.

[0035] Reference Figure 2 and Figure 4 The clamping member 43 includes two rotating rods 431 and two thread grooves 432 opened on the moving seat 42. The rotating rod 431 is rotatably connected to the fixed seat 41. The end of the rotating rod 431 facing the moving seat 42 is provided with an external thread that matches the corresponding thread groove 432. The end of the rotating rod 431 away from the moving seat 42 extends out of the fixed seat 41, and the end surface is provided with a cross groove 4311. The two rotating rods 431 are respectively located on both sides of the length direction of the scraper 5.

[0036] Reference Figure 2 and Figure 4 The rotating rod 431 will not be separated from the fixed seat 41. The operator can connect and disconnect the rotating rod 431 and the movable seat 42 by only rotating the rotating rod 431. Compared with the common connection of bolts and nuts, it can prevent the loss of connecting parts and simplify the operation of the clamping member 43.

[0037] Reference Figure 2 and Figure 3A convex strip 451 is fixedly provided on the side surface of the two clamping ends 45 facing each other, and grooves 51 matching the convex strip 451 are respectively provided on the two side surfaces of the scraper 5, and the length direction of the groove 51 is parallel to the length direction of the scraper 5. The cooperation between the convex strip 451 and the groove 51 can further limit the position of the scraper 5 between the two clamping ends 45, reduce the probability of displacement of the scraper 5, and improve the stability of the scraper 5 when scraping the window surface.

[0038] Reference Figure 2 and Figure 3 There are multiple convex strips 451 and multiple grooves 51, the number of grooves 51 is greater than the number of convex strips 451, and multiple convex strips 451 are arranged along the width direction of the scraper 5, and the gaps between adjacent grooves 51 and adjacent convex strips 451 are equal. By embedding the convex strips 451 in different grooves 51, the scraper 5 can change its position within a small range, and can slightly adjust the distance between the scraper strip and the window surface, thereby achieving a good scraping effect.

[0039] Reference Figure 2 and Figure 3 Both ends of the scraper 5 have scraping portions 52, which are arranged in a tapered shape and are used to scrape the window surface. Both ends of the scraper 5 have scraping portions 52, and when the scraping portion 52 at one end is damaged, the scraping portion 52 at the other end can be used. When the scraping portions 52 at both ends are damaged, the entire scraper needs to be replaced, which can further reduce the replacement cost of the scraper.

[0040] Reference Figure 2 and Figure 5 The bracket 3 includes a moving frame 31, a bending frame 32 and a locking member 33. The top of the moving frame 31 is slidably connected to the base 1. The driving assembly 2 is used to drive the moving frame 31 to move. The bending frame 32 is bent. One end of the bending frame 32 is rotated and arranged at the bottom end of the moving frame 31 along a direction perpendicular to the sliding direction of the moving frame 31. The other end of the bending frame 32 is fixedly arranged on the fixed seat 41. The locking member 33 is used to lock the rotation angle of the bending frame 32 on the moving frame 31.

[0041] Reference Figure 1 and Figure 5 Since the scraper blade 5 is arranged toward the side of the porthole 6 when in use, it is difficult for the operator to disassemble and replace the scraper blade 5 in this state. Therefore, it is necessary to rotate the bending frame 32 so that the scraper blade 5 faces away from the porthole 6, so that the scraper blade 5 can be easily disassembled and replaced.

[0042] Reference Figure 1 The driving assembly 2 includes a conveyor belt 21 connected to the base 1 and a motor 22 fixed on the base 1 for driving the conveyor belt 21. The top of the mobile frame 31 is fixed on the conveyor belt 21.

[0043] Reference Figure 2 and Figure 5 The locking member 33 includes a gear ring 331 and a movable groove 332 provided inside the bottom end of the movable frame 31. The top end of the bending frame 32 can slide in the movable frame 31 along the rotation axis while being rotatably arranged in the movable frame 31. The gear ring 331 is coaxially fixedly arranged at the top end of the bending frame 32. The gear ring 331 is movably arranged in the movable groove 332. The inner wall of the bottom end of the movable groove 332 has a gear groove 3321 matching the gear ring 331. When the gear ring 331 moves to abut against the top wall of the movable groove 332, the gear ring 331 disengages from the gear groove 3321; when the gear ring 331 moves to abut against the bottom wall of the movable groove 332, the gear ring 331 meshes with the gear groove 3321.

[0044] Reference Figure 2 and Figure 5 When the bending frame 32 is rotated, the bending frame 32 is pushed up to make the tooth ring 331 disengage from the tooth groove 3321, and then the bending frame 32 is rotated to a suitable angle, and the bending frame 32 is released. The bending frame 32 moves downward under the action of gravity, and the tooth ring 331 engages in the tooth groove 3321. Under the cooperation of the tooth ring 331 and the tooth groove 3321, the bending frame 32 can no longer rotate.

[0045] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
