Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a refueling machine cleaning device. Background Technology

[0002] During the refueling process at gas stations, fuel often evaporates. The evaporated fuel vapor disperses into the air and eventually adheres to the surface of the fuel dispenser, which requires regular cleaning by staff.

[0003] However, existing traditional oil stain cleaning devices have significant shortcomings in the cleaning process. The main problem is that the mixture of oil-water cleaning solution tends to remain and adhere to the fuel dispenser surface after cleaning, leading to incomplete cleaning, inconvenient operation, and low efficiency. Manual wiping makes it difficult to precisely control the amount and evenness of the cleaning agent, easily resulting in uneven application of the mixture on the fuel dispenser surface. Some areas may drip due to excessive liquid, while other areas may not have enough liquid to fully dissolve the oil stains. More importantly, the residual liquid after wiping is difficult to completely remove, re-adhering to the surface and forming new mottled stains after drying, resulting in a "the more you wipe, the more mottled it becomes" phenomenon, failing to achieve thorough cleaning.

[0004] In the prior art, there are various cleaning devices. For example, patent CN222919131U discloses a cleaning clamping fixture for diesel engine parts, including a mounting frame, a drying mechanism, a clamping mechanism, and a cleaning mechanism. A motor is fixedly mounted on the left side of the mounting frame, and the output end of the motor is connected to a combination mechanism. The clamping mechanism and the cleaning mechanism are connected to the right side of the combination mechanism. The clamping mechanism is located in front of the cleaning mechanism, and an anti-slip pad is fixedly installed inside the clamping mechanism. A toolbox is provided on the right side of the mounting frame, and a water tank is provided at the top of the toolbox. A water pipe connection port is opened at the front of the water tank. A drying mechanism is rotatably connected to the top of the inner side of the mounting frame. The drying mechanism includes a fan and a heating grid. This cleaning clamping fixture for diesel engine parts is convenient and stable, facilitates cleaning of parts, can quickly dry the moisture on the parts, facilitates the replacement of cleaning brushes, and has a toolbox for convenient storage of cleaning tools. However, the motor of this cleaning clamping fixture is driven by a belt to rotate and drive multiple connecting rods to achieve clamping. It lacks a structure design to prevent clamping overload, and since it integrates cleaning and drying, it is designed for the rust prevention needs of diesel engine parts and cannot address the problem of residual liquid on the surface of the refueling machine and secondary pollution.

[0005] For example, patent application CN116511131A discloses a solenoid valve cleaning device, including a tank, a first drive mechanism, a turntable, a second drive mechanism, a clamping assembly, a pressure sensor, multiple elastic clips, and a controller. The first drive mechanism is mounted on the tank and fixedly connected to the turntable; the second drive mechanism is mounted on the first drive mechanism and connected to the clamping assembly; the clamping assembly is mounted on the turntable; the pressure sensor is mounted on the clamping assembly; multiple elastic clips are symmetrically arranged on the upper and lower surfaces of the turntable; the controller is mounted on the first drive mechanism and connected to the first drive mechanism, the second drive mechanism, and the pressure sensor. This device is highly intelligent, capable of synchronously shaking and washing multiple valve bodies and valve cores, resulting in low labor costs, good cleaning effect, high cleaning efficiency, and shortened cleaning time. Although the cleaning device uses a pressure sensor to control the clamping force, its motor and belt drive the turntable to rotate and move up and down, agitating the parts in the cleaning solution, thereby completing the soaking cleaning. Then, since fuel dispensers are large, stationary devices, they cannot be soaked and cleaned. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a fuel dispenser cleaning device that can automate the entire process from clamping and positioning, brushing, cleaning, and scraping, reducing manual operation, lowering labor intensity, and avoiding secondary pollution. Furthermore, by automatically controlling the clamping force, it effectively avoids surface damage or structural deformation of the fuel dispenser caused by excessive clamping force, while ensuring the stability of the device during long-term use.

[0007] To achieve the above and related objectives, this utility model provides a fuel dispenser cleaning device, including a mobile support mechanism, a power lifting mechanism, a clamping mechanism, and a cleaning mechanism. The cleaning mechanism includes a brushing and scraping component installed in the clamping mechanism. The power lifting mechanism is installed on the mobile support mechanism, and the clamping mechanism is installed on the power lifting mechanism and is used for adaptive centering and clamping of the fuel dispenser.

[0008] When the clamping mechanism clamps the fuel dispenser, the power lifting mechanism simultaneously drives the clamping mechanism to move up and down along the surface of the fuel dispenser. At the same time, the cleaning mechanism provides cleaning fluid to the brushing and scraping components to brush and scrape the surface of the fuel dispenser.

[0009] Furthermore, the clamping mechanism includes a clamping motor, a transmission assembly, and two clamping plates that are movably mounted on the transmission assembly. The clamping motor drives the transmission assembly to operate and causes the two clamping plates to move synchronously in opposite directions to clamp the fuel dispenser.

[0010] Furthermore, the clamping mechanism also includes a torque sensor for detecting the clamping force, which is mounted on the clamping motor.

[0011] Furthermore, the power lifting mechanism includes an electro-hydraulic component mounted on the mobile support mechanism and a fixed plate mounted on the electro-hydraulic component away from the mobile support mechanism. When the electro-hydraulic component is running, it synchronously drives the fixed plate to perform lifting and lowering movements.

[0012] Furthermore, the cleaning mechanism also includes an oil treatment fluid storage chamber mounted on a fixed plate for storing the cleaning fluid.

[0013] Furthermore, the cleaning mechanism also includes an infusion hose, the inlet of which is connected to the oil treatment liquid storage chamber, and the outlet is located inside the clamp.

[0014] Furthermore, the scrubbing and cleaning assembly includes brushes arranged in an array on the clamps.

[0015] Furthermore, the brush corresponds to the outlet position of the infusion tubing.

[0016] Furthermore, the scrubbing and cleaning assembly includes a scraper mounted on the clamp and located below the brush.

[0017] Furthermore, the mobile support mechanism includes a base plate and multiple wheels mounted on the bottom of the base plate.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] This invention first positions the fuel dispenser cleaning device at the cleaning station using a movable support mechanism. Then, the clamping mechanism is activated. Under the action of a torque sensor, the clamping mechanism automatically stops after clamping the fuel dispenser to a certain force, achieving adaptive centering and clamping. This effectively prevents surface damage or structural deformation of the fuel dispenser due to excessive clamping force, while ensuring the long-term stability of the device. After clamping, the cleaning mechanism delivers cleaning fluid to the clamping plate. Then, the power lifting mechanism is activated to synchronously move the clamping mechanism up and down along the surface of the fuel dispenser. At this time, the brushing and scraping components on the clamping plate clean the surface of the fuel dispenser, and after cleaning, scrape off any remaining liquid. Therefore, this invention can achieve fully automated operation from clamping and positioning, brushing, cleaning, and scraping, reducing manual operation, lowering labor intensity, and avoiding secondary pollution.

Detailed Implementation

[0026] Unless otherwise defined, all technical and / or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should be understood that certain features of this invention (described in the context of separate embodiments for clarity) may also be provided in combination in a single embodiment. Conversely, multiple features of this invention (described in the context of a single embodiment for brevity) may also be provided separately or in any suitable combination or, where appropriate, in any other described embodiment of this invention. Certain features described in the context of various embodiments will not be considered essential features of those embodiments unless the embodiment is inoperable without those elements. The present invention is further illustrated below by specific examples; however, it should be noted that the specific process conditions and results described in the embodiments of this invention are for illustrative purposes only and should not be construed as limiting the scope of protection of this invention. All equivalent changes or modifications made in accordance with the spirit and essence of this invention should be covered within the scope of protection of this invention.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides a fuel dispenser cleaning device, including a mobile support mechanism, a power lifting mechanism, a clamping mechanism, and a cleaning mechanism. The cleaning mechanism includes a brushing and scraping component installed in the clamping mechanism. The power lifting mechanism is installed on the mobile support mechanism, and the clamping mechanism is installed on the power lifting mechanism and is used for adaptive centering and clamping the fuel dispenser. When the clamping mechanism clamps the fuel dispenser, the power lifting mechanism synchronously drives the clamping mechanism to move up and down along the surface of the fuel dispenser. At the same time, the cleaning mechanism provides cleaning fluid to the brushing and scraping component to brush and scrape the surface of the fuel dispenser.

[0028] Furthermore, the mobile support mechanism of this application is used to position the fuel dispenser cleaning device at the fuel dispenser cleaning station, enabling rapid positioning to different fuel dispenser locations, reducing the difficulty of manual handling, and improving work efficiency. The mobile support mechanism includes a base plate 1, with four mounting plates 2 at the bottom of the base plate 1, and each mounting plate 2 is equipped with a wheel 3. The wheel 3 can be a swivel wheel or other small wheel with a braking function.

[0029] Furthermore, the power lifting mechanism of this application includes an electro-hydraulic component 4 mounted on a movable support mechanism and a fixed plate 5 mounted on the electro-hydraulic component 4 away from the movable support mechanism. When the electro-hydraulic component 4 operates, it synchronously drives the fixed plate 5 to perform lifting movements. Even further, the electro-hydraulic component 4 is mounted on a base plate 1, and the fixed plate 5 on top of it serves as a mounting platform for the upper structure. This application utilizes the electro-hydraulic component 4 to provide vertical displacement, enabling the cleaning structure to cover different height areas on the surface of the refueling machine, achieving automated lifting and adjustment.

[0030] Furthermore, such as Figures 1 to 3 As shown, the clamping mechanism of this application includes a clamping motor 6, a transmission assembly, and two clamping plates 11 movably mounted on the transmission assembly. The clamping motor 6 drives the transmission assembly to operate, and drives the two clamping plates 11 to move synchronously in opposite directions to clamp the fuel dispenser. Furthermore, the transmission assembly of this application includes a roller 7, a belt 8, mounting blocks 9, and support rods 10. The clamping motor 6 is mounted on the lower surface of the fixed plate 5. The output end of the clamping motor 6 is connected to the roller 7. The belt 8 is mounted on the roller 7. The two mounting blocks 9 are installed through both ends of the belt 8. Support rods 10 are fixedly mounted on the two mounting blocks 9, and clamping plates 11 are mounted on the two support rods 10. The working principle of the clamping mechanism of this application is that the clamping motor 6 drives the roller 7 to rotate, which drives the mounting blocks 9 on both sides to move synchronously in opposite directions through the belt 8, ultimately causing the clamping plates 11 to clamp the fuel dispenser.

[0031] Furthermore, the clamping mechanism also includes a torque sensor for detecting the clamping force, which is mounted on the clamping motor 6. Under the action of the torque sensor, the clamping mechanism automatically stops clamping the fuel dispenser when a certain force is applied, achieving adaptive centering and clamping of the fuel dispenser. This effectively avoids surface damage or structural deformation of the fuel dispenser due to excessive clamping force, while ensuring the long-term stability of the device. The aforementioned "certain force" is set according to actual needs and is not specifically limited here.

[0032] Furthermore, the cleaning mechanism also includes an oil stain treatment fluid storage chamber 12 mounted on the fixed plate 5 for storing the cleaning fluid. The cleaning fluid in this application can be an oil stain treatment fluid or other liquid. The cleaning mechanism also includes two infusion hoses 13, the inlets of which are connected to the oil stain treatment fluid storage chamber 12, and the outlets of which are located inside the clamping plate 11.

[0033] Furthermore, the brushing and scraping assembly of this application includes brushes 14 arranged in an array on the clamping plate 11. The assembly also includes a scraper 15 mounted on the clamping plate 11 and located below the brushes 14. Even further, this application uses the mechanical movement of the brushes 14 to evenly distribute the cleaning fluid and brush away oil stains from the surface of the fuel dispenser, thus solving the problem of uneven distribution of cleaning fluid in traditional cleaning equipment. The scraper 15 scrapes away any remaining fluid and guides it away from the fuel dispenser surface, thereby avoiding secondary contamination. In addition, the brushes 14 correspond to the outlet positions of the infusion hose 13, ensuring that the cleaning fluid is accurately delivered to the area requiring cleaning and immediately utilized by the rotating or reciprocating brushes 14.

[0034] Furthermore, the working process of the refueling machine cleaning device of this application is as follows:

[0035] During operation, the device moves under the action of the mobile support mechanism. When it reaches the cleaning station of the fuel dispenser, it completes its positioning. At this time, the clamping motor 6 drives the roller 7 to move, which in turn drives the belt 8 for transmission. Under the action of the belt 8, the two clamping plates 11 move synchronously in opposite directions. Under the action of the torque sensor, they adaptively center and clamp the fuel dispenser. After clamping, the infusion hose 13 draws cleaning agent from the oil sludge treatment liquid storage chamber 12 onto the clamping plates 11. Then, under the action of the power lifting mechanism, the clamping plates 11 move up and down to scrub the surface of the fuel dispenser. After cleaning, the scraper 15 scrapes off the liquid residue on the surface of the fuel dispenser.

[0036] Furthermore, this application utilizes a combination design of brush 14 and scraper 15 to achieve uniform application of the oil stain treatment liquid and immediate scraping of residual liquid, significantly improving cleaning thoroughness and overcoming the secondary pollution problem caused by liquid residue in traditional cleaning methods. The device is equipped with a mobile chassis with wheels 3 at the bottom, allowing for quick positioning to different refueling pump locations. Combined with the electro-hydraulic components 4, it achieves automatic lifting, reducing the difficulty of manual handling and adjustment, and improving work efficiency. The clamping motor 6, transmission components, and electro-hydraulic components 4 work together to achieve fully automated operation from clamping and positioning to cleaning and scraping, reducing manual operation steps and labor intensity. Both the clamping mechanism and the cleaning mechanism are integrated on the fixed plate 5, resulting in a compact spatial layout and good motion coordination, avoiding compatibility issues when multiple devices are working together and improving overall reliability.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
