Description

Technical Field

[0001] This utility model belongs to the field of safety early warning technology, specifically relating to a self-cleaning gas station safety early warning device. Background Technology

[0002] The safety warning devices at conventional gas stations are usually cameras that can observe heat sources. These devices can only observe temperature changes within the gas station and can only issue warnings to staff when the temperature rises abnormally or an open flame appears. Furthermore, gas pumps may be subject to collisions with vehicles, and conventional safety warning devices cannot provide advance warnings or proactive defenses against such incidents.

[0003] Patent 202020116194.2 discloses an intelligent anti-collision device for gas stations, comprising a support platform. The support platform is equipped with a detection device for detecting the distance between a vehicle and the platform and outputting a detection signal, and a control device coupled to the detection device for receiving signals and outputting control signals. Anti-collision frames that cooperate with vehicle wheels are vertically slidably connected underground around the support platform. An elastic element for driving the anti-collision frames upward and a limiting element for restricting the position of the anti-collision frames are provided underground. The limiting element is coupled to the control device. When a vehicle approaches the support platform to a warning distance, the control device activates and outputs a control signal to the limiting element, causing the limiting element to engage the locking mechanism on the anti-collision frames. At this time, the anti-collision frames move upward to their highest point to impede the vehicle wheels. This technical solution can improve the safety performance of gas pumps and reduce safety hazards.

[0004] However, the aforementioned technical solutions cannot provide cushioning. If a gas pump is subjected to a heavy impact, it can damage the internal structure of the pump, such as causing the fuel line to rupture or the meter to break. In such cases, the pump may leak fuel, have inaccurate metering, or even cause safety accidents such as fires or explosions. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning safety early warning device for gas stations, overcoming the aforementioned technical problems in the prior art.

[0006] Therefore, the technical solution provided by this utility model is as follows:

[0007] A self-cleaning gas station safety early warning device includes a base plate and a control system. The base plate is provided with a safety island and a guardrail. The guardrail is located outside the safety island, and the safety island is symmetrically provided with concrete layers.

[0008] A buffer tank is fixed on the concrete layer. A millimeter-wave radar, a glass cover, and a cleaning device are installed on the buffer tank. The millimeter-wave radar is located inside the glass cover and is used to send signals to the control system. The cleaning device contains a brush and is located outside the glass cover. The glass cover can rotate relative to the cleaning device.

[0009] The buffer tank is divided into a hydraulic zone and a pneumatic zone. A buffer device is provided on the outer periphery of the buffer tank. The hydraulic zone and the pneumatic zone are connected to the buffer device. Both the hydraulic zone and the pneumatic zone are connected to the electrical signals of the control system.

[0010] The buffer tank is provided with a load-bearing column at the upper end, and a cavity is opened in the load-bearing column. A motor is fixed in the cavity, and a bearing plate is provided above the cavity. The bearing plate is rotatably connected to the inner wall of the load-bearing column. The output shaft of the motor is connected to an output rod, and the output rod is fixedly connected to the center of the bearing plate. The glass cover is fixedly connected to the bearing plate circumferentially, and the cleaning shell is fixedly connected to the load-bearing column.

[0011] The buffer tank is fixedly installed with partition one and partition two. Partition one and partition two are horizontally arranged from bottom to top. The area between partition two and the top of the buffer tank is the air pressure zone, and the area between partition one and the bottom of the buffer tank is the hydraulic zone.

[0012] A water inlet pipe and an air inlet pipe are provided between partition one and partition two. A hydraulic gauge is installed on the water inlet pipe, and a pressure gauge is installed on the air inlet pipe. One end of the water inlet pipe passes through partition one and connects to the hydraulic zone. The other end of the water inlet pipe passes through the buffer tank and connects to a water pump. One end of the air inlet pipe passes through partition two and connects to the air pressure zone. The other end of the air inlet pipe passes through the buffer tank and connects to an air pump. Both the water pump and the air pump are located on the concrete layer.

[0013] The hydraulic gauge, air pressure gauge, water pump, and air pump are all connected to the control system's electrical signals.

[0014] The buffer device includes buffer device one and buffer device two. Buffer device one is provided in multiple units and is respectively connected to the hydraulic zone and the pneumatic zone. Buffer device two is provided on the outer wall of the buffer barrel between the hydraulic zone and the pneumatic zone.

[0015] The buffer device includes a slide cylinder, and a slide rod is installed inside the slide cylinder.

[0016] The second buffer device includes a second slide cylinder, on the inner wall of which a spring damper is fixedly installed. Both the force-bearing end of the spring damper and one end of the slide rod are fixedly fitted with buffer pads.

[0017] The beneficial effects of this utility model are:

[0018] The self-cleaning gas station safety warning device provided by this utility model can detect moving objects within a 120-degree angle in front of the vehicle through the cooperation of millimeter-wave radar, glass cover and cleaning shell. When a vehicle crashes into the safety island at high speed, the millimeter-wave radar can detect it in time and send a warning signal to the on-duty personnel.

[0019] The glass cover and millimeter-wave radar of this utility model can rotate. When rotating, a brush is installed on the inner surface of the cleaning shell. The brush can rub and clean the dust on the glass cover when it rotates, enabling it to achieve a self-cleaning function. This fills the gap in the existing gas station safety warning equipment that does not have the ability to predict collisions with vehicles.

[0020] This invention utilizes the cooperation between a pneumatic zone, a hydraulic zone, a sliding rod, a buffer pad, and a spring damper. The pneumatic and hydraulic zones can push the sliding rod with the pressure generated inside, allowing the sliding rod and the buffer pad to work together to buffer part of the impact force. The spring damper is shorter than the sliding rod, allowing the spring damper and the sliding rod to buffer the huge impact brought by the car in batches. Attached Figure Description

However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to fully and completely disclose the present invention and to fully convey its scope to those skilled in the art. The terminology used in the exemplary embodiments shown in the drawings is not intended to limit the present invention. In the drawings, the same units / elements are referred to by the same reference numerals.

[0029] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning. Example

[0030] This embodiment provides a self-cleaning safety early warning device for gas stations, such as... Figure 1 As shown, it includes a base plate 1 and a control system. The base plate 1 is provided with a safety island 2 and a guardrail 3. The guardrail 3 is located outside the safety island 2, and the safety island 2 is symmetrically provided with concrete layers 4.

[0031] A buffer tank 8 is fixed on the concrete layer 4. A millimeter-wave radar 5, a glass cover 6, and a cleaning device are installed on the buffer tank 8. The millimeter-wave radar 5 is located inside the glass cover 6 and is used to send signals to the control system. The cleaning device has a brush inside and is located outside the glass cover 6. The glass cover 6 can rotate relative to the cleaning device.

[0032] The self-cleaning gas station safety warning device provided by this utility model can detect moving objects within a 120-degree angle in front of the vehicle through the cooperation between millimeter-wave radar 5, glass cover 6 and cleaning shell 7. When a vehicle crashes into the safety island 2 at high speed, the millimeter-wave radar 5 can detect it in time and send a warning signal to the on-duty personnel.

[0033] The glass cover 6 and the millimeter-wave radar 5 can rotate. When rotating, the inner surface of the cleaning shell 7 is equipped with a brush. The brush can rub and clean the dust on the glass cover 6 when it rotates, enabling it to achieve a self-cleaning function. This fills the gap in the existing gas station safety warning equipment that does not have the ability to predict collision vehicles.

[0034] The concrete layer 4 increases the overall weight and impact resistance of the safety island 2, preventing the impact of some vehicles automatically disengaging their engines upon impact. A buffer tank 8 is fixedly installed on the concrete layer 4, and multiple reflective strips can be laid on the surface of the buffer tank 8 to provide warnings to the driver. Example

[0035] Based on Example 1, this example provides a self-cleaning gas station safety early warning device, such as... Figure 3 As shown, the buffer tank 8 is divided into a hydraulic zone 11 and a pneumatic zone 12. A buffer device is provided on the outer periphery of the buffer tank 8. The hydraulic zone 11 and the pneumatic zone 12 are connected to the buffer device. Both the hydraulic zone 11 and the pneumatic zone 12 are connected to the electrical signals of the control system.

[0036] The buffer device is used to buffer the impact force of the vehicle. When the buffer device is pressurized, the hydraulic control system detects that the pressure in the pressure zone and the air pressure zone 12 increases rapidly in a short period of time, and then sends an early warning signal to the on-duty personnel. Example

[0037] Based on Example 1, this example provides a self-cleaning gas station safety early warning device, such as... Figure 4 As shown, the upper end of the buffer tank 8 is provided with a load-bearing column 23, and a cavity 24 is opened inside the load-bearing column 23. A motor 25 is fixed inside the cavity 24. A support plate 27 is provided above the cavity 24. The support plate 27 is rotatably connected to the inner wall of the load-bearing column 23. The output shaft of the motor 25 is connected to an output rod 26. The output rod 26 is fixedly connected to the center of the support plate 27. The glass cover 6 is circumferentially fixed to the support plate 27. The cleaning shell 7 is fixedly connected to the load-bearing column 23.

[0038] like Figure 5 As shown, the cavity 24 provides support for the motor 25, and the inner wall of the load-bearing column 23 is equipped with a bearing, which is sleeved on the outer surface of the output rod 26, thereby making the output rod 26 more flexible when rotating. Example

[0039] Based on Example 2, this example provides a self-cleaning gas station safety early warning device, such as... Figure 2 As shown, a first partition 9 and a second partition 10 are fixedly installed inside the buffer tank 8. The first partition 9 and the second partition 10 are horizontally arranged from bottom to top. The area between the second partition 10 and the top of the buffer tank 8 is the air pressure zone 12, and the area between the first partition 9 and the bottom of the buffer tank 8 is the hydraulic zone 11.

[0040] A water inlet pipe 15 and an air inlet pipe 16 are provided between the first partition 9 and the second partition 10. A hydraulic gauge 13 is installed on the water inlet pipe 15, and a pressure gauge 14 is installed on the air inlet pipe 16. One end of the water inlet pipe 15 passes through the first partition 9 and connects to the hydraulic zone 11. The other end of the water inlet pipe 15 passes through the buffer tank 8 and connects to the water pump 17. One end of the air inlet pipe 16 passes through the second partition 10 and connects to the pressure zone 12. The other end of the air inlet pipe 16 passes through the buffer tank 8 and connects to the air pump 18. Both the water pump 17 and the air pump 18 are located on the concrete layer 4.

[0041] The hydraulic gauge 13, air pressure gauge 14, water pump 17 and air pump 18 are all connected to the control system's electrical signals.

[0042] The water inlet pipe 15 is fixedly installed to the inner wall of partition 9, and the air inlet pipe 16 is fixedly installed to partition 10. The water pump 17 can pump liquid into the hydraulic zone 11 through the water inlet pipe 15, and the air pump 18 can deliver high-pressure gas to the air pressure zone 12 through the air inlet pipe 16, thereby maintaining a stable pressure between the air pressure zone 12 and the hydraulic zone 11. The hydraulic gauge 13 can detect the pressure of the hydraulic zone 11 below partition 9 through the water inlet pipe 15, and the air pressure gauge 14 can detect the pressure of the air pressure zone 12 above partition 10 through the air inlet pipe 16. The obtained data is summarized and sent to the control system. When the hydraulic and air pressures increase rapidly in a short period of time, the control system will issue an early warning to the on-duty personnel. Example

[0043] Based on Example 2, this example provides a self-cleaning gas station safety early warning device, such as... Figure 3 As shown, the buffer device includes buffer device one and buffer device two. Buffer device one is provided in multiple units and is respectively connected to hydraulic zone 11 and pneumatic zone 12. Buffer device two is provided on the outer wall of buffer barrel 8 between hydraulic zone 11 and pneumatic zone 12.

[0044] like Figure 3 As shown, both the hydraulic zone 11 and the pneumatic zone 12 are connected to multiple buffer devices. The buffer devices 1 and 2 resist the impact force brought by the car collision. When the maximum bearing capacity of the equipment is exceeded, the buffer tank 8 will break, and the high-pressure water in the hydraulic zone 11 will dilute the oil sprayed by the fuel dispenser. Example

[0045] Based on Embodiment 5, this embodiment provides a self-cleaning gas station safety warning device. The buffer device includes a slide cylinder 19, and a slide rod 20 is installed inside the slide cylinder 19.

[0046] The second buffer device includes a second slide cylinder 21, and a spring damper 22 is fixedly installed on the inner wall of the second slide cylinder 21. A buffer pad 28 is fixedly installed on both the force-bearing end of the spring damper 22 and one end of the slide rod 20.

[0047] The pneumatic zone 12 and the hydraulic zone 11 can push the slide rod 20 with the pressure generated inside, so that the slide rod 20 and the buffer pad 28 cooperate to buffer part of the impact force. The length of the spring damper 22 is shorter than that of the slide rod 20, so that the spring damper 22 and the slide rod 20 buffer the impact brought by the car in batches.

[0048] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
