Description
Technical Field
The invention relates to a translational wiper for vehicles and ships, in particular to a translational wiper device based on screw rod transmission.
Background
The translation wiper is widely applied in the fields of vehicles, ships and the like and is used for dewatering a personnel window. However, as the translation stroke of the wiper arm is longer, the opening on the machine body shell is needed in the translation area for the wiper arm to move, so that the inner cavity of the wiper is difficult to be completely sealed with the external environment, and substances such as external water, sand dust and the like easily enter the cavity of the transmission part. The conventional ship, vehicle wiper and the like are only used in rainy days and the like, and the influence of external rainwater and a small amount of dust entering the cavity of the transmission part on the wiper is small.
The air cushion ship is a special ship, and the whole ship is supported by inflating the apron at the bottom of the ship through the lift fan, so that the ship body leaves the water surface/the ground, and can sail at a high speed and freely sail between the water surface and the land. Because the bottom apron of the air cushion ship is not of a closed structure, larger gas leakage flows, when the air cushion ship sails on water, larger water mist can be excited to splash, when the air cushion ship sails on land, larger sand dust can be excited, the whole ship body can be covered by the water mist and the sand dust, and water and sand dust on a driving window are required to be removed by a wiper to ensure the sight of a driver. The air cushion ship needs to use the wiper once going out, and the service time of the wiper is far longer than that of a conventional ship. When the hovercraft sails on sea and land, sea water with high corrosiveness and a large amount of sand dust are excited, and the operation of the wiper is greatly influenced after the sea water and the sand dust enter the inner cavity of the transmission part. Various wipers are replaced in the long-term use process of the real ship of the hovercraft, and the real ship is extremely easy to break down after being used for a period of time.
Therefore, the translational wiper is required to be invented, the sealing problem between the cavity of the transmission part of the wiper and the external environment is solved, and the use reliability of the translational wiper under severe environment is improved.

Detailed Description
Embodiments of the present invention will be specifically explained below with reference to the drawings.
As shown in fig. 1, the invention mainly comprises a fixed machine body 1, a driving part 2, a screw rod 3, a polish rod 4, a sliding block 5, an organ cover 6, a sealing strip 7 and a scraping arm 8.
As shown in fig. 2. The machine body 1 is divided into a sealed cavity 10 and a semi-sealed cavity 11, and the two cavities are separated by a fixed partition 9. The driving part 2 is arranged in the sealed cavity, one end of the screw rod 3 extends into the sealed cavity and is connected with the driving part 2, and the driving part 2 can drive the screw rod 3 to rotate. The screw rod 3 can adopt mature modes such as sealing rings as rotating parts to seal, so that the tightness of a sealing cavity is ensured, the driving part ② of the core is prevented from being influenced by external water vapor and sand dust, and the reliability of the wiper is improved.
As shown in fig. 3 to 5, a screw thread is arranged on the screw rod 3; the polish rod 4 is a whole cylinder; one side of the sliding block 5 is provided with a threaded hole, and the other side is provided with a unthreaded hole which is respectively matched with the screw rod 3 and the polished rod 4. The screw rod 3 and the polish rod 4 are combined to limit the rotation of the sliding block 5. Similar to the bolts and nuts, when the screw rod 3 rotates and the sliding block 5 cannot rotate, the sliding block translational movement can be realized by matching the threads on the sliding block 5 with the threads on the screw rod. The scraping arm 8 is fixedly connected with the sliding block 5, and the sliding block 5 can drive the scraping arm 8 to translate, so that the translation type water scraping function is realized.
As shown in fig. 5, since the wiper arm 8 needs to translate, an opening in the machine body 1 is necessary to provide a space for translating the wiper arm 8. 2 elastic sealing strips 7 are arranged at the opening of the machine body 1, and the scraping arm 8 can slide between the 2 sealing strips 7. The sealing strip 7 is squeezed open at the position 2 with the scraping arm 8, and the sealing strip 7 rebounds to seal the opening at the position 2 without the scraping arm 8. When the external environment is very bad, the sealing measure still has the possibility of leakage of a small amount of water vapor and sand dust, but compared with the conventional wiper without any measure, the environment in the semi-sealed cavity can be greatly improved. On the basis of this sealing measure, 1 organ cover 6 is arranged on both sides of the slide block 5 to further improve the sealing performance: the organ cover 6 surrounds the screw rod 3 and the polish rod 4, one end of the organ cover 6 is connected to the sliding block 5, the other end of the organ cover 6 is connected to the machine body 1, the organ cover 6 can be compressed or stretched, and when the organ cover 6 is pulled and pressed, a break does not appear; when the sliding block 5 moves, the organ cover 6 on one side is stretched, and meanwhile, the organ cover 6 on the other side is compressed, but the screw rod in the organ cover 6 can be ensured to be always in a sealed state, so that the moving part is ensured not to be influenced by external vapor and sand.
The above detailed description of the specific embodiments of the invention is given by way of example only, and the invention is not limited to the specific embodiments described above, but any equivalent modifications and substitutions for those skilled in the art are also within the scope of the present invention. Accordingly, equivalent changes and modifications are intended to be included within the scope of the present invention without departing from the spirit and scope thereof. The scope of the invention is defined by the appended claims and equivalents.
