Technical Field

[0001] The present invention relates to ship equipment, in particular to an intelligent rust knocking device for ships. Background Art

[0002] Large cargo ships operate on the ocean for long periods of time, exposed to the wind and sun, as well as the erosion of seawater hitting the deck, causing serious rust on the ship's deck. In addition to their hard work, ocean-going crew members also need to derust the deck under the scorching sun and then spray it with rust inhibitors to reduce the rate of damage to the ship.

[0042] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0043] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] refer to Figure 1-1 0. The present invention provides an intelligent rust knocking device for ships, comprising a controller 9, a fixed bracket 1, a traveling assembly and a rust knocking assembly 2. The rust knocking assembly 2 and the traveling assembly are fixed to the lower part of the fixed bracket 1. The controller 9 is fixedly connected to the upper part of the fixed bracket 1. The rust knocking assembly 3 is used to knock the rust on the deck. The traveling assembly drives the rust knocking assembly 2 to change position. The controller 9 is used to control the movement of the traveling assembly and the rust knocking assembly 2.

[0046] refer to Figure 1 The rust knocking device further includes a radar scanning mechanism and a camera mechanism, both of which are electrically connected to the controller 9;

[0047] When the rust knocking device is working, the radar scanning mechanism and the camera mechanism first collect information and transmit the collected information to the controller 9. The controller 9 confirms the range of rust that needs to be knocked out based on the collected information.

[0048] The controller 9 draws the area to be rusted into a drawing, marks the longitude and latitude lines on the drawing, and then outputs the drawing to an external electronic device, such as a mobile phone, computer, tablet, or remote control; the combination of longitude and latitude lines can mark all positions on the deck.

[0049] The operator marks the weld locations on the deck according to the drawings. After receiving the weld location information, the controller marks the weld locations as restricted striking locations. Since the weld locations cannot be aligned for striking, it will affect the strength of the weld.

[0050] The controller 9 controls the rust knocking assembly 2 to automatically knock out the rust, and automatically excludes the restricted knocking position. The restricted knocking position is the weld position, and of course other positions that cannot be knocked can also be set through the APP so that the rust knocking device avoids these positions.

[0051] In a preferred embodiment, when the rust knocking device is in operation, the radar scanning device and the camera device scan for obstacles in real time. When a temporary obstacle is detected, a signal is transmitted to the controller 9, which controls the rust knocking device to avoid it in time. Since the rust knocking device may be encountered during deck operations or when the crew is moving around, the rust knocking device can automatically avoid the obstacle.

[0052] In a preferred embodiment, reference Figure 6 The rust knocking assembly 2 includes a rust knocking mechanism 3, which includes a cylinder 31, a movable rod 32 and a cover 33. The cylinder 31 defines a receiving cavity with one end open. The movable rod 32 is located in the receiving cavity. The cover 33 is fixedly connected to the cylinder 31 and covers the receiving cavity. The movable rod 32 moves up and down along the receiving cavity. Figure 8-10, the movable rod 32 is provided with a first air cavity 321 and a second air cavity 322. The first air cavity 321 is located above the second air cavity 322. An electronic switch is provided at least between the second air cavity 322 and the air pump. The movable rod 32 is also provided with an air bleed hole 323. The air bleed hole 323 is connected to the first air cavity 321. Both the first air cavity 321 and the second air cavity 322 are connected to an external air pump. The air pump introduces gas into the first air cavity 321 to increase its air pressure. The air pressure presses the movable rod 32 downward. When the movable rod 32 moves down to the air bleed hole 323 and is exposed from the air cylinder part 31, the pressure in the first air cavity 321 is released. After the movable rod 32 hits the deck, the reaction force causes the movable rod 32 to move upward. The air bleed hole 323 is covered again, and the air pressure in the first air cavity 321 increases again. This is repeated, which can imitate a hammer hitting the deck, thereby knocking off the rust. Reference Figure 10-1 The knocking member includes a knocking head 34 and a plurality of knocking rods 35. The knocking head 34 is fixedly connected to the lower end of the movable rod 32, and a second air cavity 322 is sealed. The first end of the knocking rod 35 is located in the second air cavity 322, and the second end of the knocking rod 35 passes through the knocking head 34 and extends out from the lower part of the knocking head 34. Due to the second air cavity 322, the knocking head 34, and the knocking rods 35, air pressure can press the knocking rods 35 downward. When the reaction force exerted by the deck on the knocking rods 35 is too great, the knocking rods 35 will retract. The multiple knocking rods 35 can be adjusted according to the shape of the deck surface, making them suitable for rust spots of different shapes. Even the bottom of a bowl-shaped rust spot can be cleaned, achieving a better rust removal effect.

[0053] refer to Figure 10-2 In a preferred embodiment, the pressure in the first air chamber 321 is greater than the pressure in the second air chamber 322, and a connecting air path 37 is provided between the two chambers. The connecting air path 37 is provided with a one-way pressure valve for opening when the pressure in the second air chamber 322 exceeds the pressure in the first air chamber 321. Due to the air pressure in the second air chamber 322, an elastic cavity is formed during the rust knocking process. Pressure changes occur as the knocking rods 35 slide up and down. When multiple knocking rods 35 move upward sufficiently, the pressure in the second air chamber 322 may exceed the pressure in the first air chamber 321, indicating that the knocking force is strong. However, if the knocking force exceeds a certain level, the rust spots will be pressed against the shipboard. Even if the main rust is removed, the remaining rust marks will be more difficult to clean. After painting, new rust spots will quickly form. In the present application, the arrangement of the connecting air path 37 and the one-way pressure valve ensures that when the pressure in the second air chamber 322 exceeds the pressure in the first air chamber 321, the pressure in the second air chamber 322 is released into the first air chamber 321, thereby preventing excessive pressure in the second air chamber 322 and ensuring its elastic function. Of course, the two air chambers can also be pressured by independent air pumps, and when the pressure in the second air chamber 322 falls below a preset value, air is added to increase the pressure.

[0054] Referring to Figure 10, in a preferred embodiment, the first end of the knocking rod 35 is provided with a rod head, the diameter of the rod head is larger than the diameter of the knocking rod 35, and the upper part of the rod head is provided with an air pressure groove, that is, a groove formed on the surface of the rod head, and the air pressure acts on the knocking rod 35 with greater force.

[0055] refer to Figure 9 As shown in Figure 10, in a preferred embodiment, a sealed oil groove 311 is further provided on the cylinder member 31, the oil inlet 313 of the sealed oil groove 311 is located at the upper part of the cylinder member 31, and the oil outlet 312 of the sealed oil groove 311 is located on the inner side of the cylinder member 31 and is communicated with the accommodating cavity. A small amount of oil in the sealed oil groove 311 can penetrate into between the movable rod 32 and the cylinder member 31 through the oil outlet 312.

[0056] refer to Figure 9 10 , in a further preferred embodiment, an annular groove 324 is provided on the outer surface of the movable rod 32. When the movable rod 32 moves to a predetermined position, the annular groove 324 overlaps the oil inlet 313. At this time, the oil inlet 313 is no longer sealed, and the oil intake can be increased, thus playing the role of oil sealing and lubrication.

[0057] refer to Figure 7 and Figure 8 In a preferred embodiment, the rust knocking mechanism 3 further includes an elastic member 36. The elastic member 36 is also located in the container. The elastic member 36 is located between the movable rod 32 and the cover body 33. One end of the elastic member 36 is fixed to the movable rod 32, and the other end is a free end. In one embodiment, the elastic member 36 is a spring. In another embodiment, the elastic member 36 is a buffer pad. The buffer pad is made of metal material. A buffer air groove is formed between the buffer pad and the cover body 33. The buffer air groove is connected to the air pump. When the movable rod 32 is rebounded, it first collides with the buffer pad. The buffer pad can play a buffering role due to the effect of air pressure. In this embodiment, the buffer pad seals the first air cavity 321 of the movable rod 32.

[0058] refer to Figure 4 and Figure 5 In a preferred embodiment, the rust knocking assembly 2 also includes a connecting rod 4 and a fixed box 5, one end of the connecting rod 4 is fixed on the fixed box 5, and the other end is connected to the fixed bracket 1; a plurality of rust knocking mechanisms 3 are provided, and the rust knocking mechanisms 3 are fixed in the fixed box 5, and the rust knocking heads 34 of the rust knocking mechanisms 3 extend out of the lower part of the fixed box 5.

[0059] refer to Figure 4 and Figure 5In a preferred embodiment, the knocking box includes a box body 51 and a box cover 52. A lower fixing hole 511 is provided at the bottom of the box body 51, and an upper fixing hole 521 is provided on the cover body 33. The cover body 33 of the rust knocking mechanism 3 includes a cover edge and a cover body, and the diameter of the cover edge is larger than the diameter of the cover body. The diameter of the cover body is adapted to the diameter of the upper fixing hole 521, and the diameter of the cover edge is larger than the diameter of the upper fixing hole 521. The diameter of the rust knocking head 34 is adapted to the diameter of the lower fixing hole 511, and the diameter of the air cylinder part 31 is larger than the diameter of the lower fixing hole 511. The rust knocking mechanism 3 is fixed in the fixing box 5 by the upper fixing hole 521 and the lower fixing hole 511. Specifically, the rust knocking head 34 is inserted into the lower fixing hole 511. After the cover body 33 is closed, the cover body is inserted into the upper fixing hole 521. Since the diameter of the cover edge is larger than the upper fixing hole 521, the diameter of the air cylinder part 31 is larger than the lower fixing hole 511. After the box cover 52 is fixed on the box body 51, the rust knocking mechanism 3 can be fixed in the knocking box.

[0060] refer to Figure 4 and Figure 5 In a preferred embodiment, the connecting rod 4 is a pneumatic telescopic rod, and the rust knocking assembly 2 also includes a buffer spring 41, which is sleeved on the connecting rod 4, one end of the buffer spring 41 abuts against the knocking box, and the other end abuts against the fixed bracket 1. When the knocking device knocks the deck, a relatively strong vibration will be generated, and the buffer spring 41 offsets the intensity of the vibration. In a preferred embodiment, the rust knocking head 34 and the movable rod 32 are detachably fixedly connected. If the rust knocking head 34 is damaged, a new rust knocking head 34 can be replaced. Different rust knocking heads 34 can also be selected as needed. For example, the pattern of the rust knocking head 34 can be replaced as needed, and a rust knocking head 34 without a knocking rod 35 can also be selected. In another embodiment, the rust knocking device also includes a head cover 6, which is sleeved on the outside of the rust knocking head 34, and the head cover 6 and the rust knocking head 34 are detachably fixedly connected. In this embodiment, the head cover 6 and the rust knocking head 34 are clamped and fixed, and the head cover 6 can be installed as needed.

[0061] refer to Figure 2 In a preferred embodiment, the walking assembly includes multiple rollers 7 and a motor 8, the rust knocking assembly 2 is located between the multiple rollers 7, the motor 8 drives the rollers 7 to rotate, and a handle 10 and a controller 9 are fixed on the fixed bracket 1, and the controller 9 and the motor 8 are electrically connected; the rust knocking device also includes an obstacle sensor, which is also electrically connected to the controller 9, so that the rust knocking equipment can automatically knock rust.

[0062] refer to Figure 3 In a preferred embodiment, a control box 20 is provided on the upper portion of the fixed bracket, and the power supply, controller 9 and air pump are fixed in the control box 20.

[0063] During operation, the rust knocking device is pushed to the position where rust needs to be knocked off, and the power supply and air pump are connected; then, the height of the rust knocking mechanism 3 is adjusted by the pneumatic telescopic rod, and the air cylinder part 31 covers the air vent 323; the air pump is turned on, and negative pressure is first drawn to retract the movable rod 32; the height of the rust knocking mechanism 3 is adjusted again, so that the height of the rust knocking head 34 is at a suitable position from the deck; the mode of the air pump is adjusted so that it inflates the first air cavity 321 and the second air cavity 322 and enters the rust knocking mode; when knocking off rust, after knocking on the same position for a predetermined time, the rust knocking mechanism 3 automatically moves and changes the knocking position.

[0064] The ship deck rust knocking device of the present invention is provided with a rust knocking mechanism 3, which includes an air cylinder 31, a movable rod 32 and a cover 33. The movable rod 32 is provided with a first air cavity 321 and an air bleed hole 323. When the air pump inflates the first cavity, the air pressure can press the movable rod 32 down. When the air bleed hole 323 is exposed from the air cylinder, the gas in the first air cavity 321 is exposed from the air bleed hole 323. The force exerted by the movable rod 32 colliding with the deck will cause the movable rod 32 to rebound, and then the next round of knocking action will be performed, which can imitate the knocking action of a hammer.

[0065] Due to the provision of the second air cavity 322, the rust knocking head 34 and the knocking rod 35, the air pressure can press the knocking rod 35 downward. When the reaction force exerted by the deck on the knocking rod 35 is too large, the knocking rod 35 will retract. The multiple knocking rods 35 can be adjusted according to the shape of the deck surface, so that they can be used for rust spots of different shapes. Even the bottom of the rust spot in the bowl can be cleaned, and the rust removal effect is better.

[0066] Since the air cylinder member 31 is provided with a sealing oil groove 311 and the outer surface of the movable rod 32 is provided with an annular groove 324, when the movable rod 32 moves to a predetermined position, the annular groove 324 and the oil inlet 313 coincide with each other. At this time, the oil inlet 313 is no longer sealed, and a small amount of sealing oil will enter between the air cylinder member 31 and the movable rod 32, playing the role of oil sealing and lubrication.

[0067] An elastic member 36 is provided between the movable rod 32 and the cover 33 to buffer the movable rod 32;

[0068] A head cover 6 is provided, or the rust knocking head 34 and the movable rod 32 are detachably fixedly connected, the rust knocking head 34 or the head cover 6 can be replaced, and the state of the knocking rod 35 can be selected when in use;
