Description

Technical Field

[0001] This utility model relates to the technical field of snowplow fuel tanks, and in particular to a hot-blowing snowplow fuel tank with a wave-proof, explosion-proof, and vibration-proof structure. Background Technology

[0002] As a core piece of equipment for road maintenance in frigid regions, hot-air snowplows rapidly melt and remove snow from road surfaces using high-temperature airflow. These vehicles are typically powered by high-powered internal combustion engines and equipped with dedicated fuel tanks for storage. When hot-air snowplows operate in frigid conditions, the impact of fluid sloshing, the pressure difference from fuel extraction, and the vibrations from engine operation pose significant challenges to the large-capacity fuel tanks. Therefore, optimizing the fuel tank structure of current hot-air snowplows is becoming increasingly important.

[0003] With increasing demands for reliability, safety, and stability in the fuel tanks of hot-blown snowplows, the traditional fuel tank structure has revealed significant shortcomings. Traditional fuel tanks lack fluid dynamics design, leading to violent fuel sloshing during vehicle start-up, stopping, and operation on slopes. This creates high-energy fuel waves, which not only easily cause false alarms from the level sensor and reduced fuel supply stability, but more importantly, the static electricity generated by the friction between the high-speed impact of the fuel and the tank walls poses a risk of combustion and explosion in the fuel-air mixture. Furthermore, the large temperature fluctuations of fuel during hot-blown snowplow operation make conventional vent designs prone to clogging and failure, leading to excessive internal pressure that causes tank deformation and even weld tearing. Negative pressure conditions can cause tank collapse and fuel supply interruption. In addition, when snowplows travel on bumpy roads, vibrations from the engine and chassis are directly transmitted to the fuel tank body through rigid connections. Under long-term alternating stress, welds are prone to fatigue cracks, and vibration accelerates the loosening of internal components, leading to failure of anti-surge structures and damage to seals, significantly increasing the risk of fuel leakage. Therefore, designing a fuel tank for a hot-blowing snowplow with wave-proof, explosion-proof, and vibration-proof functions has become an urgent problem to be solved. Utility Model Content

[0021] In this application, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-6 As shown, a fuel tank for a hot-blowing snowplow with anti-wave, explosion-proof, and vibration-damping structures includes a fuel tank body, a manhole cover assembly 2, a support seat anti-vibration mechanism 12, and a baffle anti-wave mechanism. The manhole cover assembly 2 is located on the top of the fuel tank body. Multiple support seat anti-vibration mechanisms 12 are located at the bottom of the fuel tank body, and a baffle anti-wave mechanism is located inside the fuel tank body.

[0024] The baffle wave-damping mechanism includes a horizontal baffle 17, a longitudinal baffle 19, and a vertical plate 16. Several horizontal baffles 17 are fixedly connected in parallel at intervals inside the tank body. The longitudinal baffles 19 are fixedly connected vertically in the middle of the tank body. The longitudinal baffles 19 divide the tank body into two connected cavities. The horizontal baffles 17 and the longitudinal baffles 19 are arranged perpendicularly. The two ends of the horizontal baffles 17 are fixedly connected to the vertical plates 16, and the vertical plates 16 are fixed to the inner wall of the tank body.

[0025] Specifically, the longitudinal partition 19 divides the single fuel tank into two connected chambers, effectively reducing the vertical impact of the fuel due to inertia when the vehicle accelerates in the vertical direction. Simultaneously, three sets of transverse partitions 17 are welded to the inner wall of the fuel tank to cut through sloshing oil waves, further reducing damage to the fuel tank caused by oil surges. Vertical plates 16 reinforce the connection between the transverse partitions 17 and the inner wall of the fuel tank, increasing the partition strength and ensuring that the welds of the transverse partitions 17 will not tear under long-term impact.

[0026] The manhole cover assembly 2 includes a manhole cover flange 20, a connecting cylinder 22, a connecting flange 23, and a breather valve 21. The bottom of the connecting cylinder 22 is fixedly connected to the top of the oil tank body, and the top of the connecting cylinder 22 is fixedly connected to the connecting flange 23. The top of the connecting flange 23 is fixedly connected to the manhole cover flange 20, and the breather valve 21 is connected to the manhole cover flange 20.

[0027] Specifically, the connecting cylinder 22 is welded to the top of the top plate 3 of the oil tank. The manhole cover is sealed by the connecting flange 23 and the manhole cover flange 20, and a sealing gasket is used between the flanges to prevent oil leakage. The breather valve 21 has a pressure self-balancing function and is installed on the manhole cover flange 20 as an integrated structure. When the oil tank is detected to be in a high temperature or fire environment, it can automatically release the pressure inside the tank to prevent explosion. At the same time, it can also prevent oil vapor evaporation and protect the safety of the oil tank. When the pressure inside the tank exceeds the set value, it will automatically open to balance the pressure difference between the inside and outside and prevent the tank body from collapsing due to negative pressure.

[0028] The vibration damping mechanism 12 of the support base includes an upper support plate 27, a lower support plate 32, a vibration damping pad 29, and a large washer 33. The top of the upper support plate 27 is fixedly connected to the bottom of the fuel tank body. The lower support plate 32 is provided below the upper support plate 27 and is fixedly connected to the vehicle body. The vibration damping pad 29 is connected between the upper support plate 27 and the lower support plate 32. The bottom of the vibration damping pad 29 is provided with a large washer 33. The bolt 31 passes through the bottom of the vibration damping pad 29 and the large washer 33 and is connected with a nut.

[0029] The fuel tank body includes a top plate 3, a bottom plate 13, a left side plate 5, a right side plate 11, a front sealing plate 7, and a rear sealing plate 15, which are fixedly connected together. Both the front sealing plate 7 and the rear sealing plate 15 have a wavy bending structure, which can increase the strength of the fuel tank body and prevent the fuel tank body from bulging due to excessive impact of the fuel when the vehicle accelerates or stops suddenly.

[0030] A liquid level pipe 9 is connected to the rear sealing plate 15, and the liquid level pipe 9 is connected to the interior of the oil tank body. A grounding strip 4 is also connected to the bottom of the rear sealing plate 15.

[0031] Specifically, since shaking can easily cause static electricity to accumulate between the oil in the tank and the tank wall due to friction, the risk of combustion and explosion can be reduced by setting a grounding strip 4 so that the tank body can contact the ground.

[0032] A lifting ring 8 is fixedly connected to the top plate 3, and the main fuel filler port 1 is also connected to the top plate 3. A spare fuel filler port 10 is connected to the top of the right side plate 11, and the spare fuel filler port 10 is connected to the interior of the fuel tank body.

[0033] Specifically, external fuel enters the fuel tank body through the main filler port 1. When emergency refueling is needed, the backup filler port 10 can be used for refueling. During the refueling process, the fuel level in the liquid level pipe 9 can be observed to determine whether the fuel tank is full. The fuel in the fuel tank is supplied to the turbojet engine through the fuel outlet 14.

[0034] The base plate 13 is also connected to a drain outlet 6 and an oil outlet 14. The drain outlet 6 and the oil outlet 14 are respectively connected to the interior of the oil tank body. The top of the base plate 13 is also connected to a filter screen 18, which is located inside the oil tank body and is connected to the oil outlet 14.

[0035] Specifically, before the fuel flows out of the fuel tank, it needs to be coarsely filtered through filter screen 18 to remove larger particles and prevent impurities from causing incomplete combustion in the turbojet engine or damaging the internal structure of the engine.

[0036] Specifically, when oil supply is not required, sewage can be drained through the drain port 6, which is equipped with a minimum liquid level. At the same time, the manhole cover assembly 2 can be opened for oil tank maintenance.

[0037] A sensor placement plate 24 is provided on the manhole cover flange 20, and multiple temperature sensors are installed on the sensor placement plate 24.

[0038] An ultrasonic level sensor, a temperature sensor, and a pressure sensor are installed on the sensor placement plate 24.

[0039] Specifically, the ultrasonic level sensor transmits the remaining oil level information to the cab in real time via electrical signals. The temperature sensor monitors the oil temperature inside the tank and is equipped with high and low temperature warning functions. The pressure sensor monitors the pressure inside the tank and works in conjunction with the breather valve for differential pressure adaptive adjustment. The sensor on the manhole cover, working in coordination with the pressure self-balancing breather valve, provides explosion-proof protection.

[0040] A transparent observation cover 26 is provided on the manhole cover flange 20, and a base 25 is also provided on the manhole cover flange 20 for locking the observation cover.

[0041] Specifically, the base 25 includes two fixed seats and two connecting plates. The two fixed seats are fixedly connected to the manhole cover flange and are located on the same straight line. Each fixed seat is rotatably connected to a connecting plate via a hinge shaft. The two connecting plates are arranged opposite each other and overlap each other. When it is necessary to check the fuel status but it is inconvenient to remove the manhole cover, the inspection can be carried out through the observation cover 26. Simply open the two connecting plates to expose the observation cover 26.

[0042] The upper support plate 27 is U-shaped, and upper stiffening plates 28 are uniformly fixedly connected inside the upper support plate 27. The lower support plate 32 is L-shaped, and lower stiffening plates 30 are fixedly connected to both sides of the wall of the lower support plate 32.

[0043] Specifically, the upper support plate 27 is welded to the bottom plate 13 of the fuel tank, and the upper stiffening plate 28 increases the supporting strength. The lower support plate 32 is welded with a lower stiffening plate 30 and is bolted to the frame. A high-damping elastic connection mechanism is used to flexibly connect the upper and lower support plates. Specifically, bolts 31 are used to limit the vertical displacement of the support plates, and large washers 33 and high-damping damping pads 29 are used to further attenuate vibrations caused by vehicle movement or engine operation. The high-damping elastic connection mechanism weakens the vibration transmitted through the connection, thus achieving a vibration damping effect.

[0044] The usage process of this utility model is as follows: First, refueling is performed, with fuel injected into the fuel tank body through the main filler port 1 at the top. When the main filler port 1 is unavailable, emergency refueling can be performed through the spare filler port 10 on the right side plate 11. During refueling, the fuel level can be monitored in real time through the level tube 9 on the rear sealing plate 15 to prevent overfilling.

[0045] Afterwards, normal fuel supply is carried out, and the fuel in the fuel tank flows to the fuel outlet 14 at the bottom plate 13 under the action of gravity. Before flowing out, the fuel will first pass through the filter screen 18 for coarse filtration, effectively intercepting larger particulate impurities, ensuring that the fuel supplied to the turbojet engine is clean, and preventing incomplete combustion or damage to the internal structure of the engine.

[0046] During operation, the longitudinal baffles inside the fuel tank divide the oil into two connected chambers, effectively suppressing vertical impact. Multiple transverse baffles perform three-dimensional cutting of the swaying oil waves, significantly reducing surge intensity, ensuring stable fuel supply, protecting the tank structure, and achieving the anti-surge function.

[0047] Pressure sensors, temperature sensors, and ultrasonic level sensors monitor the tank's internal status in real time. The breather valve, integrated into the manhole cover assembly, automatically adjusts the pressure difference between the inside and outside of the tank based on sensor data to prevent excessively high or low pressure from causing tank deformation and to achieve explosion-proof functionality.

[0048] The vibration damping mechanism of the support seat connecting the fuel tank and the vehicle body effectively attenuates vibrations from the engine and road surface through high-damping vibration damping pads, protecting the fuel tank welds and internal structure, and preventing fatigue cracks caused by long-term vibration, thus achieving the vibration damping function.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
