Description

Technical Field

[0001] This application relates to the technical field of shipbuilding, and more particularly, to a ship wiper device. Background Art

[0002] Currently, there are mainly two types of wipers used on ships: translational wipers and Kent window wipers.

[0003] As Figure 1 shown, the translational wiper scrapes rainwater, snowflakes, thin ice, etc. outside the window through the parallel reciprocating movement of the wiper blade to ensure clear visibility for the crew inside the cockpit. The operating frequency of the translational wiper is about 40 - 50 times per minute. Therefore, in severe weather conditions such as sea storms and ice and snow weather, due to the long span of the ship's cockpit side window, it is difficult for the translational wiper to ensure the cleaning efficiency due to reasons such as its slow reciprocating movement frequency. At the same time, when the wiper blade moves back and forth at high speed, it will interfere with the crew's line of sight.

[0004] As Figure 2 shown, the Kent window wiper has a structure of a circular glass and a metal frame. The center of the glass is connected to the motor, and the motor drives the glass to rotate to throw off rainwater, snowflakes, thin ice, etc. attached to the glass, so as to keep the glass in a relatively clear and transparent state. The Kent window wiper has a motor, a power supply wire, a metal frame, etc. arranged on the side facing the cabin. The motor speed is about 1400 RPM per minute, and it will generate noise when turned on, which has a certain impact on the crew observing the outside through it inside the cabin.

[0005] Moreover, the glass diameter of the Kent window wiper is 35 cm. Therefore, the field of view of the Kent window wiper is limited, and the effective field of view also needs to remove the area blocked by the motor, making the field of view even more limited. According to the centrifugal force calculation formula: F = ω2×r×m, where F is the centrifugal force, ω is the angular velocity, r is the radius, and m is the mass of the object. If the radius of the glass is increased to increase the field of view, the centrifugal force of the Kent window wiper will increase exponentially, and the stability of the Kent window wiper device cannot be guaranteed.

[0006] In summary, an improved technical solution is needed to address the deficiencies of the above-mentioned existing technologies. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0036] See Figures 3 to 7 , this application specifically provides a ship wiper device, including:

[0037] Two rotating parts, each rotating part at least includes a roller 2 and a fixed shaft 19, the roller 2 is rotatably connected to the fixed shaft 19, and the two rotating parts are arranged in parallel at a predetermined distance apart;

[0038] It should be noted that the drum 2 is controlled to rotate by a motor, and the motor is arranged outside the cockpit to prevent the running noise of the motor from being transmitted into the cockpit and affecting the people in the cockpit.

[0039] It should also be noted that the rotation speed and rotation direction of the drum 2 are controlled by a motor.

[0040] A water retaining belt 1, which is connected at the head and tail to form a ring and then covered on two rollers 2. The water retaining belt 1 is stretched and unfolded by the two rollers 2. The rotation of the two rollers 2 drives the water retaining belt 1 to rotate in a circular manner;

[0041] The wiper portion 4 at least includes a wiper strip 21 and a support frame 20. The support frame 20 is fixedly connected to the fixed shaft 19 and then covered on the upper part of the water retaining belt 1. The arrangement direction of the support frame 20 is perpendicular to the circular rotation direction of the water retaining belt 1. The top of the wiper strip 21 is fixedly connected to the support frame 20 and extends downward, and the bottom of the wiper strip 21 abuts against the water retaining belt 1. During the rotation of the water retaining belt 1, the bottom of the wiper strip 21 scrapes and cleans the surface of the water retaining belt 1.

[0042] In the present application, after the water retaining belt 1 rotates with the drum 2, the attachments on the water retaining belt 1 are scraped off after contacting the wiper strip 21. By fixing the position of the wiper strip 21, the wiper strip 21 is prevented from affecting the operator's vision during the wiping process.

[0043] In an practicable manner, the length of the support frame 20 corresponds to the width of the water retaining belt 1, so that the length of the wiper strip 21 can cover the width of the water retaining belt 1. The two ends of the support frame 20 are respectively fixedly connected to the two ends of the fixed shaft 19, and when the water retaining belt 1 rotates with the drum 2, the attachments on the water retaining belt 1 are scraped off after contacting the wiper strip 21.

[0044] Specifically, the wiper strip 21 is a long double-layer rubber strip to ensure a scraping effect.

[0045] In one practicable manner, Figure 6 As shown, the water retaining belt 1 is a multi-layer structure, including at least a conductive layer 11, and the conductive layer 11 is an indium tin oxide conductive layer (Indium Tin Oxide Conductive Layer, referred to as ITO conductive layer). The conductive layer 11 heats the water retaining belt 1 after being energized. The conductive layer 11 in this embodiment can produce a uniform, stable and efficient heating effect after being energized, which can effectively prevent the formation of fog and water vapor on the outer layer of the water retaining belt 1, and can also accelerate the evaporation of liquid attachments on the surface of the water retaining belt 1.

[0046] In one practicable manner, Figure 6As shown, a first base layer 12 is provided on one side of the conductive layer 11 close to the drum 2. The first base layer 12 is used to support the conductive layer 11 and increase the hardness of the conductive layer 11. The first base layer 12 is a polyethylene terephthalate base layer (abbreviated as PET base layer). In this application, technologies such as physical vapor deposition or chemical vapor deposition are used to deposit and form the conductive layer 11 on the surface of the first base layer 12.

[0047] In an implementable manner, a first positive electrode contact piece 5 and a first negative electrode contact piece 6 are respectively provided at both ends of the drum 2. Both the first positive electrode contact piece 5 and the first negative electrode contact piece 6 are circular rings and are attached to the outer surface of the drum 2. The two ends in the width direction of the conductive layer 11 are bent downward to form first extending ends 17; after the water retaining belt 1 is sleeved on the drum 2, the two side first extending ends 17 are respectively in contact with the first positive electrode contact piece 5 and the first negative electrode contact piece 6, so that the conductive layer 11 obtains stable and uninterrupted external power supply.

[0048] In an implementable manner, as Figure 6 shown, the water retaining belt 1 further includes a coating layer 13, and the coating layer 13 is an electrochromic coating layer 13 (abbreviated as EC coating layer). Under the action of an external electric field, the electrochromic material of the coating layer 13 will reversibly change its own color, and the light transmittance of the coating layer 13 is adjusted by changing the energization parameters. Through the setting of the coating layer 13, in a strong light environment, by applying an external electric field to the coating layer 13, the coating layer 13 changes from transparent to semi-transparent, dark and other multi-level atomization effect forms, which can reduce or completely block the amount of strong light entering.

[0049] In an implementable manner, as Figure 5 shown, a second positive electrode contact piece 7 and a second negative electrode contact piece 8 are respectively provided at both ends of the drum 2. Both the second positive electrode contact piece 7 and the second negative electrode contact piece 8 are circular rings and are attached to the outer surface of the drum 2. The two ends in the width direction of the coating layer are bent downward to form second extending ends 18, and the second extending ends 18 are respectively in contact with the second positive electrode contact piece 7 and the second negative electrode contact piece 8, so that the coating layer obtains stable and uninterrupted external power supply.

[0050] It should be noted that when used as a sunshade for a ship's cockpit, it is adjusted to a semi-transparent form according to the needs of the crew. On the premise that it can be used as a sunshade window, it can avoid blocking the view.

[0051] It should also be noted that as Figure 6As shown, a second base layer 14 is provided on the side of the coating layer 13 close to the roller 2, and the second base layer 14 is used to support the coating layer 13. The coating layer 13 is deposited on the second base layer 14 by techniques such as physical vapor deposition. The second base layer 14 is a PET base layer. By providing the second base layer 14, the adhesion of the EC coating layer is increased.

[0052] In an implementable manner, as Figure 6 shown, the water blocking strip 1 further includes a first substrate layer 10 and a second substrate layer 15. The conductive layer 11 and the coating layer 13 are both sandwiched between the first substrate layer 10 and the second substrate layer 15. Both the first substrate layer 10 and the second substrate layer 15 are polyimide layers (Cellulose Polyimide Layer, abbreviated as CPI layer). The colorless and transparent CPI layer has good optical transparency, low thermal expansion coefficient and mechanical properties, and serves as the support structure of the water blocking strip 1.

[0053] In an implementable manner, as Figure 6 shown, a hydrophobic layer 9 is provided on the outermost side of the water blocking strip 1 away from the roller 2. The hydrophobic layer 9 is a transparent waterproof film, which can reduce the adhesion of rain, ice, snow and other substances, and improve the efficiency of the wiper strip 21 to remove attachments.

[0054] It should be noted that the hydrophobic layer 9 is provided on the outermost side of the water blocking strip 1 by spraying. If the hydrophobic effect decreases after a period of use, spraying repair can be carried out at any time.

[0055] In an implementable manner, as Figure 3 shown, there are two wiper parts 4, and the two wiper parts 4 are respectively arranged at the positions of the two rollers 2, and the two wiper parts 4 are backup to each other; when one of the wiper parts 4 fails, the roller 2 rotates in reverse so that the other wiper part 4 works to ensure the normal use of the present application.

[0056] In an implementable manner, the wiper part 4 further includes a hot air part. The hot air part is arranged on the support frame 20. The hot air part at least includes a heating wire and a blower. The hot air part is used to output hot air with a predetermined temperature and a predetermined air output volume to the water blocking strip 1 for blowing and drying the remaining attachments remaining on the water blocking strip 1 after being scraped by the wiper strip 21.

[0057] In an implementable manner, as Figure 7As shown, the wiper part 4 further includes a pulley 22 and a pulley shaft. The pulley shaft is arranged vertically and is fixedly connected between the support frame 20 and the fixed shaft 19 of the drum 2. The pulley 22 is sleeved on the pulley shaft, and the outer surface of the pulley 22 is an H-shaped groove. The side edges of the water blocking belt 1 are arranged in the H-shaped groove so that the pulley 22 limits both ends of the water blocking belt 1 in the width direction to assist in the conveyance of the water blocking belt 1.

[0058] In an implementable manner, as Figure 5 shown, a rubber sleeve 3 is sleeved on the drum 2. The rubber sleeve 3 is connected between the water blocking belt 1 and the drum 2 to prevent the water blocking belt 1 from being worn during the cyclic rotation process.

[0059] In an implementable manner, baffles 16 are arranged on both sides of the water blocking belt 1 in the width direction. The baffles 16 and the water blocking belt 1 form a sealed space to cover structures such as the drum 2 in the sealed space.

[0060] In an implementable manner, the present application further includes a control unit. The control unit is electrically connected to the motor and the power supply of the water blocking belt 1. The control unit is used to control the rotation speed and rotation direction of the motor, and is also used to control the opening and closing of the power supply and the adjustment of the power supply parameters.

[0061] It should be noted that the control unit can also accurately control the motor and the power supply of the water blocking belt 1 according to real-time meteorological conditions, such as information on wind speed, wind direction, humidity, temperature, air pressure, etc.

[0062] Specifically, when the temperature is relatively low or when deicing is required at the first startup, the control unit controls the hot air part to be turned on and the conductive layer 11 to be energized to accelerate the deicing operation. When one side motor fails, the control unit controls the other side motor to rotate in the reverse direction to restore the wiper function.

[0063] In summary, the present application provides a ship wiper device for severe meteorological conditions. After the motor controls the drum 2 to rotate, it drives the water blocking belt 1 to rotate cyclically. And the wiper strip 21 is used to remove attached rainwater, ice, snow, fog, stains and other attachments. Through the setting of the water blocking layer, rainwater, snowflakes, thin ice, spray, etc. can be blocked; and through the setting of the multi-layer structure, functions such as hydrophobicity, improving the support force, accelerating the evaporation of surface liquid attachments, increasing the coating adhesion, and changing the light input amount can also be achieved. The present application solves problems such as low efficiency of the reciprocating movement of the wiper, limited cleaning effect, and narrow field of vision.

[0064] Specifically, through the setting of the conductive layer 11, heating the water stop belt 1 can effectively prevent the formation of fog and water vapor on the outer layer of the water stop belt 1, and also play a role in accelerating the evaporation of liquid attachments on the surface of the water stop belt 1. Through the setting of the coating layer 13, the light transmittance of the coating layer 13 can be adjusted by changing the energization parameters, and the amount of strong light entering can be adjusted on the premise of ensuring that the vision is not affected. Through the setting of the hydrophobic layer 9, the adhesion of rain, ice, snow and other substances can be reduced, and the efficiency of the wiper strip 21 in removing attachments can be improved. By arranging the drum 2 at both ends, the crew can obtain a complete and clear outward view of the porthole size; through the setting of the two wiper parts 4, the two wiper parts 4 are used as backups for each other; when one of the wiper parts 4 fails, the drum 2 rotates in reverse to enable the other wiper part 4 to work, ensuring the normal use of this application. Through the setting of the hot air part, hot air with a predetermined temperature and a predetermined air output volume is output to the water stop belt 1 to blow and dry the remaining attachments remaining on the water stop belt 1 after being scraped by the wiper strip 21.

[0065] In this embodiment, the rotation speed of the drum 2 is 500 RPM, the radius of the rubber sleeve 3 is 5 cm, and the length of the porthole is 1 m. According to the linear velocity formula: linear velocity = rotation speed × 2 × π × radius, the running distance of the water stop belt 1 in this embodiment per minute is 157 m, that is, in this embodiment, the porthole with a length of 1 m is cleaned 157 times. This is much higher than the cleaning frequency of 40 - 50 times per minute of the translational windshield wiper. And the cleaning efficiency of this application can be further improved by increasing the rotation speed of the motor.

[0066] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
