Description

Technical Field

[0001] This invention relates to the field of road emergency response devices and equipment, specifically a push-and-walk type oil-absorbing cotton sheet safety paving device. Background Technology

[0002] In recent years, sudden oil spills on the tarmac have continued to occur, including but not limited to oil spills from aircraft vents, oil spills from aircraft refueling connectors that suddenly fall off, oil spills from burst hoses at ground well connections, and oil spills from failed or missing seals on ground well valve connections. When flammable and explosive fuel leaks onto the tarmac or runway, it not only poses a risk to passing vehicles and other aircraft, but more importantly, the diffusion, evaporation, and reaction of this aviation fuel on the ground can, if not promptly contained, expand the affected area and even potentially endanger human health.

[0003] Existing conventional road cleaning equipment can sweep away debris such as gravel and sand from apron surfaces. For example, Chinese invention patent application CN201910439329.0 discloses an airport pavement sweeper, which includes a chassis, a cargo box, and a driver's cab. A suction and sweeping device is located on the lower front side of the chassis. A fan is mounted on the chassis, and symmetrically arranged folding tow frames are located on both sides of the chassis's center. A cleaning blanket and a magnetic suction device are connected to the folding tow frames, with the magnetic suction device located behind the cleaning blanket. Symmetrically arranged air vents are located on both sides of the rear of the chassis, connected to the fan. The cleaning blanket first sweeps up the debris and collects it in a mesh cover; then, the magnetic suction device performs a secondary cleaning of the metal parts on the airport and apron pavement, ensuring the pavement is clean and residue-free.

[0004] In the event of a fuel leak, the first priority is to cut off the source of the leak to prevent further leakage. Because of incidents like loose connections or burst pipes, the instantaneous leakage of fuel is extremely large, leaving a significant amount on the ground even after the leak source is cut off. Therefore, the immediate priority is to effectively limit the free flow and diffusion of the leaked fuel to minimize its spread and prevent further danger. However, common cleanup equipment is often ineffective at controlling leaked fuel. More dangerously, such equipment typically contains battery-powered control circuits or even internal combustion engines as power sources. Sparks or electrical discharges from these devices can ignite or even explode upon contact with volatile fuel mist, damaging the equipment and posing a significant safety risk to passengers and nearby personnel.

[0005] To address the aforementioned problems, this invention provides a moving, walking type oil-absorbing cotton sheet safety installation device that can safely lay oil-absorbing cotton sheets over a large area to absorb and limit fuel oil leakage in the event of flammable and explosive oil leaks. Summary of the Invention

[0006] This invention provides a moving, walking type oil-absorbing cotton sheet safety laying device that can safely lay oil-absorbing cotton sheets over a large area to absorb and limit fuel oil leakage in the event of flammable and explosive oil leakage.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0008] A push-and-walk type oil-absorbing cotton sheet safety installation device includes a main body and wheels. The main body has an internal cavity for holding the oil-absorbing cotton sheet, a discharge port at the front end of the main body, and wheels installed at the bottom of the main body. The main body also has a push mechanism for driving the oil-absorbing cotton sheet to move towards the discharge port and a discharge mechanism for driving the oil-absorbing cotton sheet out of the discharge port. A power transmission mechanism is provided between the discharge mechanism and the wheels, so that the wheels can drive the discharge mechanism to operate.

[0009] As a preferred embodiment of the present invention, the discharge mechanism includes a discharge roller capable of rotating about a horizontal axis, and the pushing mechanism includes a pushing plate movably disposed inside the main housing and a supporting pushing device disposed between the pushing plate and the rear end face of the main housing. The pushing plate can reciprocate in the front-rear direction inside the main housing, and the supporting pushing device can push the pushing plate and the oil-absorbing cotton sheet forward together, so that the oil-absorbing cotton sheet at the foremost position contacts the discharge roller.

[0010] As a preferred embodiment of the present invention, the power transmission mechanism includes a multi-station reversing component. The multi-station reversing component can form a first engagement station and a second engagement station that can be switched between each other. When the multi-station reversing component is in the first engagement station state, the forward rotation of the traveling wheel can drive the discharge roller to rotate in the forward direction, driving the oil-absorbing cotton sheet to be discharged outward. When the multi-station reversing component is in the second engagement station state, the reverse rotation of the traveling wheel can also drive the discharge roller to rotate in the forward direction, driving the oil-absorbing cotton sheet to be discharged outward.

[0011] As a preferred embodiment of the present invention, the multi-station reversing assembly further includes a third separation station, wherein when the multi-station reversing assembly is in the third separation station state, the power transmission between the traveling wheel and the discharge roller is cut off.

[0012] As a preferred embodiment of the present invention, a height adjustment device for adjusting the distance between the main body and the ground is provided between the walking wheels and the main body.

[0013] As a preferred embodiment of the present invention, the top of the main housing is provided with a window for placing an oil-absorbing cotton pad into the accommodating cavity, and the side of the main housing is also provided with a guide groove for controlling and guiding the movement of the push plate. The guide groove includes a horizontal guide section at the front and a vertical engaging section at the rear. The horizontal guide section and the vertical engaging section are interconnected. The side of the push plate is connected to a gripping drive part that can pass through the guide groove.

[0014] As a preferred embodiment of the present invention, an arc-shaped transition portion is formed between the horizontal guide section and the vertical engaging section.

[0015] As a preferred embodiment of the present invention, the front end of the push plate is tilted forward.

[0016] As a preferred embodiment of the present invention, the bottom of the main housing is connected to an oil-absorbing cotton sheet guide portion that extends outward from the discharge port.

[0017] As a preferred embodiment of the present invention, the outer peripheral surface of the walking wheel is provided with an anti-slip groove.

[0018] In summary, the present invention can achieve the following beneficial effects:

[0019] 1. The push-and-walk type oil-absorbing cotton sheet safety laying device given in this invention uses the rotation of the bottom walking wheels themselves as the driving force source during the user's push-and-walk process. At the same time, it adopts a simplified mechanical transmission mechanism to realize the arrangement and laying of oil-absorbing cotton sheets. During use, no sparks or electric sparks will be generated, so the leaked oil will not be ignited, which greatly reduces the possibility of fire and explosion and improves the safety during emergency handling.

[0020] 2. The push-walking oil-absorbing cotton sheet safety laying device given in this invention realizes the separation of multiple stacked oil-absorbing cotton sheets from each other through the discharge mechanism, and then discharges each sheet independently for laying. At the same time, the cylindrical discharge roller can pull the oil-absorbing cotton sheet out of the main box during rotation, while initially compressing the oil-absorbing cotton sheet and making it fully unfolded, so as to eliminate the problem of local folding or curling of the oil-absorbing cotton sheet, so that the oil-absorbing cotton sheet can fully contact the fuel present on the ground, thereby realizing the adsorption and control of leaked fuel.

[0021] 3. The push-and-walk type oil-absorbing cotton sheet safety laying device given in this invention can also achieve stable unidirectional discharge of oil-absorbing cotton sheets from the inside to the outside from the discharge port, regardless of whether the device is pushed forward or backward, through the internally set multi-station reversing component, giving the user greater operational flexibility. In addition, since the switching between forward and reverse walking and discharge states can be achieved with simple operation, when multiple layers of oil-contaminated ground need to be placed, it is only necessary to push the device back and forth in the target area while controlling the change of working state, without having to walk in circles to reach the target location again, thus simplifying the operation of the device. At the same time, the multi-station reversing component can also cut off the power transmission between the walking wheels and the discharge mechanism, so that when the device walks across a local area of ​​oil-free ground, it will not lay oil-absorbing cotton sheets outward, and also reduce the resistance encountered when pushing and transferring the device.

[0022] 4. The push-walking oil-absorbing cotton sheet safety paving equipment given in this invention also includes a height adjustment device that can change the distance between the discharge port and the ground, enabling the equipment to have good passing and paving capabilities in more complex road areas.

[0023] 5. In the push-walking oil-absorbing cotton sheet safety laying device provided by the present invention, the front end of the push plate used to push the oil-absorbing cotton sheet forward is inclined, and at the same time, an oil-absorbing cotton sheet guide part is also extended outward at the discharge port, so that the oil-absorbing cotton sheet can be smoothly led outward from the main box, avoiding the problem of stacking and jamming during the discharge process.

[0046] The following specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0047] This solution is achieved through the following technical means:

[0048] Example 1: In this example, a push-and-walk type oil-absorbing cotton sheet safety installation device is provided. This device includes a rectangular main box 1 formed by assembling and welding aluminum alloy plates. Walking wheels 2, which serve a load-bearing function, are installed on the outer side of the bottom surface of the main box 1. A hollow receiving cavity 101 is formed inside the main box 1 for placing the oil-absorbing cotton sheet B, and a forward-facing discharge port 102 is provided at the front end of the main box 1. (See attached diagram) Figure 1 In the given structure, the discharge port 102 in this embodiment is formed by removing the front plate of the main box 1, thereby making the main box 1 a forward-facing open structure, so that the accommodating cavity 101 is connected to the outside.

[0049] Inside the main housing 1, there are two parts: a pushing mechanism 3 for driving the oil-absorbing cotton sheet B to move closer to the discharge port 102, and a discharge mechanism 4 for driving the oil-absorbing cotton sheet B out of the discharge port 102.

[0050] The pushing mechanism 3 includes a pushing plate 301 that is vertically mounted inside the main housing 1 and a supporting pushing device 303 connected between the pushing plate 301 and the inner wall of the main housing 1. Specifically, to ensure the stability of the pushing plate 301 during its reciprocating movement and prevent it from tipping over, several protrusions extend outward from the outer periphery of the pushing plate 301, forming several guide grooves 104 corresponding to the protrusions. These grooves allow the protrusions to embed into the guide grooves 104, stabilizing and guiding the movement of the pushing plate 301. The supporting pushing device 303 mainly includes a compression spring horizontally arranged along the front-rear direction of the main housing 1. Both ends of the compression spring are fixedly connected to the inner wall of the main housing 1 and the rear end face of the pushing plate 301, respectively. At this time, if a backward force is applied to the front end face of the push plate 301, the push plate 301 will move backward and squeeze the compression spring. After the force is removed, the compression spring will tend to reset, thereby driving the push plate 301 to move forward.

[0051] The discharge mechanism 4 is located at the discharge port 102 and mainly includes a horizontally positioned cylindrical discharge roller 401 that can rotate around a horizontal axis of rotation. On the outer circumferential surface of the discharge roller 401, a toothed structure composed of several toothed portions 402 is formed. These protruding toothed portions 402 can engage with the fibers on the surface of the oil-absorbing cotton sheet B to a relatively light degree, allowing the discharge roller 401 to more forcefully pull the oil-absorbing cotton sheet B outwards during its rotation around its own axis. This also reduces the relative displacement between the oil-absorbing cotton sheet B and the discharge roller 401, resulting in more precise control over the laying process.

[0052] A key technical feature of the push-and-walk type oil-absorbing cotton sheet safety installation device presented in this embodiment is that it does not utilize motors, engines, or other equipment as driving devices to rotate the discharge roller 401. Instead, it uses a mechanical transmission structure to transmit the rotation generated on the walking wheels 2 when the user pushes the device to the discharge roller 401, greatly improving safety. Specifically, to achieve the transmission effect, a power transmission mechanism 5 is provided between the discharge mechanism 4 and the walking wheels 2, enabling the walking wheels 2 to drive the discharge mechanism 4. Specifically, the power transmission mechanism can adopt a belt drive, using a pulley fixedly connected to the walking wheels 2 as the driving wheel 801 and a pulley fixedly connected to the discharge roller 401 as the driven wheel 802. The driving and driven wheels 802 are then connected by a belt, enabling the oil-absorbing cotton sheets B to be sequentially discharged from the discharge port 102 when the device is pushed.

[0053] Whether it's the initial process of placing oil-absorbing cotton sheets B inside the main housing 1, or the need for operators to re-place new oil-absorbing cotton sheets B after the existing ones inside the main housing 1 have been exhausted, the presence of the aforementioned pushing mechanism 3 hinders the placement of the oil-absorbing cotton sheets B. Therefore, in this embodiment of the safe installation equipment, an auxiliary mechanism is cleverly designed to reduce the difficulty of operation. Specifically, a window 103 is provided at the top of the main housing 1 for placing the oil-absorbing cotton pad B into the accommodating cavity 101. Simultaneously, a guide groove 104 is provided on the side of the main housing 1 for controlling and guiding the movement of the push plate 301. The guide groove 104 includes a horizontal guide section 1041 at the front and a vertical engaging section 1042 at the rear, which are interconnected. A gripping drive part 302, capable of passing through the guide groove 104, is connected to the side of the push plate 301. This gripping drive part 302 is columnar and movably mounted on the push plate 301, ensuring that while driving the push plate 301 to move back and forth, the gripping drive part 302 itself can move up and down vertically relative to the push plate 301. During equipment operation, when the oil-absorbing cotton pads B inside the main housing 1 are exhausted, the push plate 301, pushed by the support and push device 303, is positioned at the front end of the main housing 1. At this time, the gripping drive part 302 is located at the front end of the horizontal guide section 1041 in the guide groove 104. The operator only needs to grasp the gripping drive part 302 and pull it backward to the position where it connects with the vertical locking section 1042, and then press the gripping drive part 302 downward to enter the vertical locking section 1042 before releasing the gripping drive part 302. At this time, the forward pushing action of the support and push device 303 is stopped by the vertical locking section 1042, thereby locking the push plate 301 at this position. To make the directional change of the gripping drive part 302 in the guide groove 104 smoother, an arc-shaped transition part 1043 is also provided between the horizontal guide section 1041 and the vertical locking section 1042. Once the push plate 301 is locked in the rear position, the operator can easily insert a new multi-layered, vertically stacked oil-absorbing cotton sheet B from the aforementioned window 103 into the main housing 1 from top to bottom. Then, by lifting the gripping drive unit 302 upward, the locking effect on the push plate 301 can be released, and the equipment installation work can be resumed.

[0054] Due to the characteristics of the fiber material used in the oil-absorbing cotton sheet B, it has a certain degree of softness. Therefore, if the oil-absorbing cotton sheet B is placed in a nearly upright position inside the main box 1, it is easy for a loose gap to appear between two layers of oil-absorbing cotton sheet B. Under the influence of gravity, one of the oil-absorbing cotton sheets B cannot maintain its upright and flat state, but will slide down and partially wrinkle and stack, hindering the laying and discharge of materials. Therefore, in this embodiment, as a preferred embodiment, the front end face of the push plate 301 is designed as an inclined surface, so that the multiple layers of oil-absorbing cotton sheets B have a vertical support effect on each other, thus avoiding the aforementioned slippage and preventing the discharge port 102 from being blocked due to the wrinkles and stacking of the oil-absorbing cotton sheets B. Furthermore, an oil-absorbing cotton sheet guide part 105 is connected to the bottom of the main box 1, which extends outward from the discharge port 102. The upper surface of the oil-absorbing cotton sheet guide part 105 is an arc shape that can transition and receive the inclined surface at the front end of the push plate 301, thereby ensuring that each oil-absorbing cotton sheet B remains in an unfolded state during the laying and discharge process and is smoothly discharged outward from the discharge port 102.

[0055] Since the ground where the push-and-walk oil-absorbing cotton pad B is safely laid inevitably contains leaked fuel A, the walking wheels 2 may slip during the installation, preventing the oil-absorbing cotton pad B from being laid smoothly. Therefore, in this embodiment, the walking wheels 2 installed in the equipment are further improved and optimized. Rubber is selected as the manufacturing material for the walking wheels 2, and a concave anti-slip groove 201 is opened on the outer circumference of the walking wheels 2. Alternatively, an anti-slip groove can be opened around the outer circumference of the walking wheels 2 to prevent the walking wheels 2 from not rotating during the pushing and laying process.

[0056] Example 2: During the design process, the inventors discovered that when fuel A leaks, the oil on the ground spreads and flows in all directions, and the amount of leaked oil varies in different areas. For example, the amount of fuel A on the ground is much greater closer to the leak than at locations farther from the leak. Correspondingly, when handling leaked fuel A, more absorbent cotton sheets B must be laid in areas with more oil to achieve more thorough absorption and containment of the fuel A. This requires the equipment to travel back and forth multiple times in certain areas to lay more absorbent cotton sheets B. Obviously, the existing unidirectional power transmission mechanism between the traveling wheel 2 and the discharge roller 401 can only lay absorbent cotton sheets B during unidirectional movement. To achieve multiple layers at the same location, it is necessary to detour back to the target area, and at the same time, unnecessary absorbent cotton sheets B are laid in non-target areas. This is clearly a wasteful and cumbersome operation, reducing work efficiency. Therefore, this embodiment presents a further improved and optimized equipment structure based on the push-walking oil-absorbing cotton sheet safety laying equipment given in Embodiment 1.

[0057] In this example, the power transmission mechanism 5 located between the traveling wheel 2 and the discharge roller 401 is no longer a unidirectional pulley or gear transmission mechanism, but includes a multi-station reversing assembly 8 capable of changing the power transmission relationship between the two components. Specifically, the multi-station reversing assembly 8, housed in its main body, includes multiple gears. The driving wheel 801 is fixedly mounted on the shaft of the traveling wheel 2 or meshes with a gear on the traveling wheel 2 at its fixed center. Similarly, the driven wheel 802 is fixedly mounted on the shaft of the discharge roller 401 or meshes with a gear on the shaft of the discharge roller 401 at its fixed center. Between the driving wheel 801 and the driven wheel 802, a triangular gear carrier 805 is installed, with its bottom corner hinged to the center of the driving wheel 801. Two meshing gears, one large and one small, are rotatably mounted on the upper two corners of the gear carrier 805, namely a first idler gear 803 and a second idler gear 804. (Refer to the appendix of the specification.) Figure 9When the gear frame 805 swings to the left, the multi-station reversing assembly 8 is in the first engagement position. The first idler wheel 803 meshes with both the driving wheel 801 and the driven wheel 802. When the user pulls the device backward, the second idler wheel 804 idles. When the driving wheel 801 rotates counterclockwise, it drives the driven wheel 802 to rotate counterclockwise as well, causing the discharge roller 401 to rotate forward, thus allowing the oil-absorbing cotton sheet B to be discharged and laid out from the discharge port 102 in the forward direction. When the gear frame 805 swings to the left, the first idler wheel 803 meshes with both the driving wheel 801 and the driven wheel 802. When the device moves to the right, the multi-station reversing assembly 8 is in the second engagement position. The first idler wheel 803 meshes with the drive wheel 801, while the second idler wheel 804 meshes with the driven wheel 802. When the user pushes the device forward in the opposite direction, the drive wheel 801 rotates clockwise, but due to the presence of the second idler wheel 804, the driven wheel 802 still rotates counterclockwise, driving the discharge roller 401 to rotate forward, thus allowing the oil-absorbing cotton sheet B to be discharged and laid out from the discharge port 102 in the forward direction. In other words, with this structure, by adjusting the engagement position of the gear frame 805, the oil-absorbing cotton sheet B can be discharged and laid out from the discharge port 102 in the forward direction regardless of whether the user drives the device forward or backward. This also allows the device to move back and forth repeatedly in a local position to lay multiple layers of oil-absorbing cotton sheet B to improve the adsorption and restriction effect on fuel A.

[0058] Furthermore, to enhance the equipment's ability to handle more complex road surfaces in actual use, a height adjustment device 6 is provided between the traveling wheels 2 and the main housing 1 to adjust the distance between the main housing 1 and the ground. Specifically, the height adjustment device 6 can be a hand-cranked screw jack; by rotating the rocker arm in both directions, the distance between the main housing 1 and the traveling wheels 2 can be changed.

[0059] To facilitate user operation of pushing or pulling the equipment, a folding push frame 7 is installed on the rear side of the main housing 1. The folding push frame 7 includes two parts: a main frame 701 and a locking rod 702. One end of the main frame 701 is hinged to the lower part of the rear end face of the main housing 1, and the front end of the locking rod 702 is hinged to the upper part of the rear end face of the main housing 1. The rear end of the locking rod 702 has a locking part 7021 that can be connected to the main frame 701. The locking part 7021 can be a hook or a pin, etc., which can realize the connection or disconnection. When the device needs to be pushed or pulled, unfold the aforementioned locking rod 702 and main frame 701, and fix the engaging part 7021 on the locking rod 702 onto the main frame 701. At this time, a stable triangular connection structure is formed between the locking rod 702, the main frame 701, and the main body box, allowing the user to push and pull. Conversely, by disengaging the connection between the locking rod 702 and the main frame 701, the two parts can be easily flipped and folded to one side of the main body box 1, effectively saving storage space.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
