Description

Technical Field

[0001] This application relates to the field of protection and sealing structure technology, and in particular to a sealing and protection structure for a refueling machine. Background Technology

[0002] With the increasing informatization and automation of gas stations, fuel dispensers, as key equipment, are often installed in open-air environments, exposed to natural conditions such as sun, rain, and sandstorms for extended periods. In rainy or snowy weather, the traditional fuel dispenser's outer casing structure has insufficient sealing, allowing rainwater to easily seep in along the top of the unit or at structural joints. This exacerbates the risk of moisture damage or corrosion to internal electronic components, affecting the normal operation and lifespan of the fuel dispenser.

[0003] Most existing fuel dispensers use a simple metal casing structure without a dedicated drainage design on top, making them prone to water accumulation and even backflow. Furthermore, the panel and computer housing are often openable, leaving gaps at the edges. Although some products use rubber strips or waterproof coatings, the seal can easily fail under long-term use or changes in temperature and humidity, leading to potential water leakage.

[0004] Therefore, a simple, reliable, and waterproof sealing structure suitable for the top and edges of fuel dispensers is particularly important to improve the overall environmental adaptability and reliability of fuel dispensing equipment. Utility Model Content

[0005] The purpose of this application is to provide a sealing and protective structure for fuel dispensers that can overcome the problems of insufficient sealing and easy water leakage in existing fuel dispensers used outdoors.

[0006] This application provides a sealing and protective structure for a fuel dispenser, employing the following technical solution: A sealing and protective structure for a fuel dispenser includes a main unit structure. A computer box for installing control circuits and a power system is mounted on the top area of ​​the main unit structure. A panel is provided on the exterior of the main unit structure and is installed within the inner wall of the computer box. A water-retaining eave is fixedly connected to the top of the main unit structure. A first water-guiding groove is provided on the top of the computer box, located on the top of the main unit structure. Second water-guiding grooves are provided on both sides of the panel, communicating with the first water-guiding grooves to form a continuous drainage path. A first sealing strip is embedded in the installation gap between the main unit structure and the computer box. The inner side of the first sealing strip is fitted against the mounting surface of the computer box, and the outer side of the first sealing strip is pressed tightly against the mounting surface of the main unit structure. A second sealing strip is embedded in the installation gap between the computer box and the panel. The outer side of the second sealing strip is pressed tightly against the mounting surface of the computer box, and the inner side of the second sealing strip is fitted against the mounting surface of the panel. The longitudinal portion is pressed tightly against the corresponding side of the computer box. Uniformly distributed heat dissipation holes are provided on the lower part of the side wall of the main unit structure.

[0007] By adopting the above technical solutions, the water-retaining eaves can initially block rainwater from directly impacting the top of the main unit structure, reducing the amount of water entering the first water guide channel; the first and second water guide channels form a continuous drainage path, which can guide rainwater to drain quickly and prevent water from accumulating on the top of the equipment and the panel area; the first and second sealing strips respectively seal the installation gaps between the main unit structure and the computer box, and between the computer box and the panel, effectively preventing rainwater or moisture from seeping in from the joints, protecting the control circuits and power system inside the computer box; the heat dissipation holes can ensure ventilation and heat dissipation of the equipment, thereby solving the problems of insufficient sealing and easy water seepage in traditional fuel dispensers, which can lead to moisture and corrosion of electronic components, and improving the environmental adaptability and service life of the equipment.

[0008] Preferably, a control panel is mounted on the outer surface of the computer case, and the control panel is electrically connected to the electrical components inside the computer case.

[0009] By adopting the above technical solution, the control panel serves as the user interface for operation and information interaction, and its stable electrical connection with the internal electrical components of the computer case facilitates its use.

[0010] Preferably, an oil gun holder is installed on the outer surface of the main unit structure, an oil gun is placed inside the oil gun holder, the input end of the oil gun is connected to an oil pipe, and the input end of the oil pipe is connected to an external oil tank.

[0011] By adopting the above technical solution, the oil gun holder provides stable support for the oil gun, while the oil pipe allows for convenient refueling of oil from external oil tanks through the oil gun.

[0012] Preferably, a maintenance sealing cover is provided at the bottom of the computer case, and the maintenance sealing cover is installed in the bottom area of ​​the host structure.

[0013] By adopting the above technical solution, the maintenance sealing cover facilitates the inspection and maintenance of the internal components of the main unit structure. Its installation and cooperation with the main unit structure can form a bottom seal, preventing ground moisture or rainwater from seeping in from the gaps at the bottom of the main unit structure, protecting the internal components, and solving the problem of water entering the bottom of traditional equipment due to the lack of sealing protection.

[0014] Preferably, the inner wall of the first water guide channel is fixedly connected to a water guide slope, and the outer surface of the water guide slope is coated with a first hydrophobic coating.

[0015] By adopting the above technical solution, the water guide slope can guide the rainwater in the first water guide channel to flow quickly to the drainage path, reducing water accumulation; the first hydrophobic coating can reduce the adhesion of rainwater on the surface of the water guide slope, accelerate drainage efficiency, and solve the problems of slow drainage and easy water accumulation in the traditional top water guide structure of equipment.

[0016] Preferably, the inner wall of the second water guide channel is coated with a second hydrophobic coating.

[0017] By adopting the above technical solution, the second hydrophobic coating can reduce the adhesion of rainwater to the inner wall of the second water guide channel, so that rainwater on both sides of the panel can be quickly discharged along the water guide channel, reducing the retention of water in the panel operation area, preventing rainwater from seeping in along the gap between the panel and the main unit structure, and solving the water seepage risk caused by poor drainage around the panel of traditional equipment.

[0018] Preferably, the side wall of the main unit structure is fixedly connected with an inclined water baffle, which is located above the heat dissipation holes.

[0019] By adopting the above technical solution, the inclined baffle can prevent rainwater from directly hitting the heat dissipation holes, allowing the rainwater to flow down along the inclined surface of the baffle. While ensuring the ventilation and heat dissipation function of the heat dissipation holes, it also prevents rainwater from entering the main unit structure through the heat dissipation holes, thus solving the problem of water easily entering the heat dissipation holes of traditional equipment.

[0020] Preferably, support piles are fixedly connected to the four corners of the bottom surface of the main structure, and an anti-slip pad is fixedly connected to the bottom end of each support pile.

[0021] By adopting the above technical solutions, the support piles raise the main structure, reducing the direct contact between ground water and the bottom of the main structure, and reducing the risk of ground moisture erosion; the anti-slip mat can enhance the stability of the equipment, prevent the equipment from shaking and creating gaps due to the slippery ground, and solve the problem that traditional equipment is easily soaked by water because its bottom is close to the ground.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This is a sealing and protective structure for fuel dispensers. It initially blocks rainwater from impacting the top of the main unit structure through a water-retaining eave, reducing the amount of water entering the first water guide channel. The first and second water guide channels form a continuous drainage path, and combined with the water-guiding slope and the first and second hydrophobic coatings, drainage is accelerated, preventing water accumulation and solving the problem of inefficient top drainage in traditional equipment. The first and second sealing strips respectively seal the gaps between the main unit structure and the computer box, and between the computer box and the panel, forming multiple seals that are more reliable than existing single seals. This prevents moisture from seeping into and protects the components inside the computer box. The three structures work together to construct a multi-layered protection system consisting of "guidance-transition-sealing," significantly enhancing the equipment's waterproof and sealing capabilities in complex environments. The heat dissipation holes, combined with the inclined water-retaining plate, provide both ventilation and waterproofing, preventing rainwater intrusion. The maintenance sealing cover enhances the bottom seal, and the support piles reduce ground water erosion. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A sealing and protective structure for a fuel dispenser, referring to... Figure 1 , Figure 4 and Figure 5The system includes a main unit structure 1, a computer case 2 for housing control circuits and a power supply system mounted on the top of the main unit structure 1, a panel 3 on the outside of the main unit structure 1, the panel 3 being installed in the inner wall of the computer case 2, a water-retaining eave 9 fixedly connected to the top of the main unit structure 1, a first water guide channel 10 on the top of the computer case 2, the first water guide channel 10 being located on the top of the main unit structure 1, a water guide slope 14 fixedly connected to the inner wall of the first water guide channel 10, and a first hydrophobic coating 15 coated on the outer surface of the water guide slope 14. The water guide slope 14 can guide rainwater in the first water guide channel 10 to flow quickly to the drainage path, reducing water accumulation; the first hydrophobic coating 15 can reduce the adhesion of rainwater on the surface of the water guide slope 14, accelerating drainage efficiency and resolving water accumulation. To address the problems of slow drainage and water accumulation in traditional equipment top water guiding structures, a second water guiding channel 11 is provided on both sides of the panel 3. The second water guiding channel 11 is connected to the first water guiding channel 10 to form a continuous drainage path. The inner wall of the second water guiding channel 11 is coated with a second hydrophobic coating 16. The second hydrophobic coating 16 can reduce the adhesion of rainwater to the inner wall of the second water guiding channel 11, so that rainwater on both sides of the panel 3 can be quickly discharged along the water guiding channel, reducing the retention of water in the operating area of ​​the panel 3 and preventing rainwater from seeping in through the gap between the panel 3 and the main structure 1. This solves the problem of water seepage caused by poor drainage around the panel of traditional equipment. Therefore, the water-blocking eaves 9, the first water guiding channel 10 and the second water guiding channel 11 can form a graded water guiding structure, optimizing the actual water guiding effect.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A first sealing strip 12 is embedded in the mounting gap between the host structure 1 and the computer case 2. The inner side of the first sealing strip 12 is in contact with the mounting surface of the computer case 2, and the outer side of the first sealing strip 12 is pressed tightly against the mounting surface of the host structure 1. A second sealing strip 13 is embedded in the mounting gap between the computer case 2 and the panel 3. The outer side of the second sealing strip 13 is pressed tightly against the mounting surface of the computer case 2, and the inner side of the second sealing strip 13 is in contact with the mounting surface of the panel 3. The longitudinal portion is pressed tightly against the corresponding side of the computer case 2. Therefore, the first sealing strip 12 and the second sealing strip 13 can achieve partial sealing. The system effectively prevents moisture, rainwater, or humid air from seeping into the internal control module through the seams, ensuring the safe operation of electronic components. The lower part of the side wall of the main unit structure 1 has evenly distributed heat dissipation holes 17. An inclined baffle 18 is fixedly connected to the side wall of the main unit structure 1. The inclined baffle 18 is located above the heat dissipation holes 17. The inclined baffle 18 can block rainwater from directly hitting the heat dissipation holes 17, allowing the rainwater to flow down along the inclined surface of the baffle. While ensuring the ventilation and heat dissipation function of the heat dissipation holes 17, it prevents rainwater from entering the interior of the main unit structure 1 through the heat dissipation holes 17, solving the problem of water easily entering the heat dissipation holes of traditional equipment.

[0034] Example 2: A sealing and protective structure for a fuel dispenser, referring to... Figure 1 , Figure 2 and Figure 3 Based on the same concept as Embodiment 1 above, this embodiment proposes that a control panel 4 be installed on the outer surface of the computer box 2. The control panel 4 is electrically connected to the electrical components inside the computer box 2. The control panel 4 serves as the interface for user operation and information interaction. Its stable electrical connection with the electrical components inside the computer box 2, under the sealing protection formed by the first sealing strip 12 and the second sealing strip 13, can prevent poor circuit contact caused by rainwater seepage, ensuring the stable operation of the equipment during user operation. This solves the problem of water seepage at the joints affecting the reliability of the connection between the operating interface and the internal circuit in traditional equipment. An oil gun holder 5 is installed on the outer surface of the host structure 1. An oil gun 6 is placed inside the oil gun holder 5. The input end of the oil gun 6 is connected to an oil pipe 7. The input end of the oil pipe 7 is connected to an external oil tank. The oil gun holder 5 provides stable support for the oil gun 6, and the oil pipe 7 can easily transfer oil from the external oil tank. The refueling is performed via the refueling nozzle 6. A maintenance sealing cover 8 is located below the computer box 2, installed at the bottom of the main unit structure 1. The maintenance sealing cover 8 facilitates the inspection and maintenance of internal components of the main unit structure 1. Its installation and cooperation with the main unit structure 1 form a bottom seal, preventing ground moisture or rainwater from seeping in through gaps at the bottom of the main unit structure 1, protecting internal components and solving the problem of water ingress due to lack of sealing protection at the bottom of traditional equipment. Support piles 19 are fixedly connected to the four corners of the bottom surface of the main unit structure 1, and each support pile 19 has an anti-slip pad fixedly connected to its bottom end. The support piles 19 raise the main unit structure 1, reducing direct contact between ground water and the bottom of the main unit structure 1, thus reducing the risk of ground moisture erosion. The anti-slip pads enhance equipment stability, preventing equipment wobbling and gaps caused by slippery ground, solving the problem of traditional equipment being easily soaked by water accumulation due to its close proximity to the ground.

[0035] In summary, this utility model, through the organic combination of a graded water guiding structure and a local sealing structure, constructs a sealing and protection system with clear partitions and pathways. While ensuring the reliability of the equipment, it effectively extends the service life of the fuel dispenser in outdoor use scenarios. It is suitable for various types of gas stations and self-service refueling equipment, and has broad application value and promotion prospects.

[0036] The implementation principle of this application embodiment is as follows: When the device is in a rainy, snowy, or high-humidity environment, the water-blocking eaves 9 surrounding the top edge of the host structure 1 first play an initial protective role. They guide some rainwater to the outside of the device through physical blocking, reducing the amount of rainwater directly impacting the top of the computer box 2. The rainwater that is not diverted by the water-blocking eaves 9 flows into the first water guide channel 10 set on the top of the computer box 2. At this time, the water guide slope 14 on the inner wall of the first water guide channel 10 guides the rainwater to flow to both sides with the help of the inclined structure. The first hydrophobic coating 15 on the surface of the water guide slope 14 reduces the adhesion of rainwater and accelerates the water flow speed, so that the rainwater moves quickly to the drain outlets on both sides or the rear of the device. Subsequently, some of the residual rainwater flowing down along the front of the device will enter the second water guide channels 11 on both sides of the panel 3. The second hydrophobic coating 16 on the inner wall of the second water guide channel 11 further enhances the drainage efficiency. Since the second water guide channel 11 is connected to the first water guide channel 10, a continuous drainage path is formed from the top to both sides of the panel 3, ensuring that the rainwater is discharged along the edge of the device and avoiding stagnation in the operating area. During drainage, if a small amount of moisture or rainwater remains near the joint, the first sealing strip 12 between the main unit structure 1 and the computer case 2 will seal the gap by adhering to the computer case 2 on the inside and pressing it against the main unit structure 1 on the outside. Meanwhile, the second sealing strip 13 between the computer case 2 and the panel 3 will adhere to and press against both the panel 3 and the computer case 2 on the inside and outside respectively, forming a double sealing barrier to prevent moisture from seeping into the computer case 2 and protect the control circuit and power system. At the same time, the heat dissipation holes 17 on the lower side wall of the main unit structure 1 are responsible for ventilation and heat dissipation of the equipment. The sloping water baffle 18 above it can prevent rainwater from directly hitting the heat dissipation holes 17, allowing the rainwater to flow down the slope and ensuring that the heat dissipation function is not affected. In addition, the support piles 19 at the bottom of the main structure 1 raise the equipment, reducing the contact between ground water and the bottom. The maintenance sealing cover 8 in the bottom area enhances the bottom sealing and prevents ground moisture from seeping up. The three structures work together to build a multi-layer protection system consisting of "guidance-transition-sealing". This structural scheme has the characteristics of clear water guiding path, specific sealing measures and clear structural layers. Without changing the original use of the fuel dispenser, it significantly improves the waterproof ability and environmental adaptability of the equipment, and is especially suitable for fuel dispensers that are exposed to the outdoors for a long time.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
