Description

Technical Field

[0001] This invention relates to the field of de-icing and snow blowing equipment, and in particular to a rear-mounted gas jet snow removal vehicle with a functional assembly. Background Technology

[0002] Timely removal of snow and ice accumulation on highways during winter is crucial for maintaining smooth traffic flow. Existing snow blowers are mostly either cold-air or gas-jet snow blowers. Cold-air snow blowers typically have their snow-blowing module located on the front and right side of the vehicle. Their advantage lies in their adaptability to different road conditions and the fact that they do not damage the nozzles when moving up and down slopes. However, they are not very effective at clearing icy or hardened road surfaces. For snow and ice removal operations on highway bridges and large bridges, there is a need to develop alternative methods to chlorine-based de-icing agents. Gas-jet snow removal vehicles possess unique ice and snow heat treatment technology, making them suitable for environmentally friendly highway maintenance without the need for de-icing agent application. However, while existing gas-jet snow blowers are suitable for relatively simple applications such as airports, they are ill-suited for the complex snow and ice conditions encountered on highways.

[0003] Regarding the technology of gas jet snow blowers, patent application CN106284180A discloses an ice and snow removal vehicle that uses gas jet de-icing. The gas generator has an air intake duct installed on its air intake casing. A fixed nozzle is connected to the rear of the gas generator. A gas distributor is connected to the rear of the fixed nozzle via a rectangular elbow. The gas distributor is divided into two pipes. The first pipe is connected to the air hammer nozzle through the middle exhaust pipe, and the second pipe is connected to the air shovel nozzle through the rear exhaust pipe. The air hammer nozzle is located at the belly of the vehicle.

[0004] Existing gas-jet snow blowers mostly use functional assemblies mounted on the underside of the vehicle. When applied to highways for snow blowing and de-icing, this can easily lead to overheating and malfunctions at the underside. Furthermore, the vehicles cannot effectively clear snow and ice from the road surface, requiring auxiliary vehicles to clear the road; otherwise, the snow and ice will accumulate after being run over. If the air duct in the engine compartment is extended to the front of the vehicle for snow blowing, the structural limitations result in numerous bends in the air duct and a forced change in the direction of the high-speed spiral airflow, leading to significant energy loss and a risk of overheating on the chassis. Currently used gas-jet snow blowers either blow snow from one side or are equipped with two engines blowing snow from both sides. The excessive air volume and speed create pressure on two-lane highways and result in significant airflow waste. Finally, the approach of mounting functional modules at the front or underside of the vehicle to achieve operational stability and road adaptability sacrifices the expandability of these modules, making under-spraying mode unusable and hindering road de-icing and drying. Summary of the Invention

[0005] The main objective of this invention is to propose a rear-mounted gas jet ice and snow removal vehicle, which aims to solve the aforementioned technical problems.

[0006] To achieve the above objectives, this invention proposes a rear-mounted gas jet snow removal vehicle, comprising a vehicle body and an aircraft engine. The vehicle body includes a front end and a cargo box, which are mounted on a chassis. The aircraft engine is mounted within the cargo box, and an engine nozzle is located at the rear end of the aircraft engine. A primary gas jet distributor and a secondary gas jet distributor are sequentially mounted on the rear axle of the chassis. The primary and secondary gas jet distributors are connected by a connector. The primary gas jet distributor is connected to the engine nozzle via a gas flow duct. The longitudinal direction of both the primary and secondary gas jet distributors is perpendicular to the vehicle's forward direction. Multiple first interfaces are located at the bottom of the primary gas jet distributor, and multiple second interfaces are located at the bottom of the secondary gas jet distributor.

[0007] Preferably, the gas diversion duct has a "Y"-shaped bifurcated structure, with the two outlet ends of the gas diversion duct connected to the inlet pipe ports at both ends of the primary gas jet distributor. The gas diversion duct is used to divert the gas jet generated by the engine nozzle in an equal manner and allow it to enter the inner cavity of the primary gas jet distributor from both ends.

[0008] Preferably, the aircraft engine is centrally mounted inside the vehicle compartment, and the centerline of the aircraft engine is parallel to the direction of travel of the vehicle body.

[0009] Preferably, the two ends of the secondary gas jet distributor are telescopic structures; the vehicle body also includes rear wheel sets, and the rear wheel sets on both sides of the rear end of the vehicle body are respectively connected to the rear axle of the chassis through hydraulic telescopic structures.

[0010] Preferably, the secondary gas jet distributor has a three-section nested structure, with the left and right sections connected to the middle section via telescopic connectors, and the left and right sections can retract into the middle section.

[0011] Preferably, an air intake is provided on the aircraft engine. The air intake is a front-mounted structure installed at the front of the aircraft engine. The air intake adopts an inverted U-shaped air intake with air intake from the side and roof of the vehicle.

[0012] Preferably, a driver's cab and a fuel equipment room are provided on the front of the vehicle, with the fuel equipment room located behind the driver's cab for providing fuel to the vehicle body and aircraft engine.

[0013] Preferably, a rear axle load-bearing connection support is provided between the rear axle of the chassis and the secondary gas jet distributor, the rear axle load-bearing connection support being used to support the secondary gas jet distributor.

[0014] Preferably, the number of the first interfaces is five, and the first interfaces are used to connect to the snow blowing and de-icing functional modules.

[0015] Preferably, the number of the second interfaces is nine, and the second interfaces are used to connect to the road drying functional module.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0017] (1) In this invention, a primary gas jet distributor and a secondary gas jet distributor are sequentially installed on the rear axle of the chassis. Multiple first interfaces are provided at the bottom of the primary gas jet distributor for connecting snow blowing and de-icing functional modules, and multiple second interfaces are provided at the bottom of the secondary gas jet distributor for connecting road drying functional modules. An aircraft engine is installed within the cargo box, resulting in a three-part structure for the entire gas jet snow removal vehicle: the first part is the front structure, the second part is the cargo box and aircraft engine, and the third part mainly consists of the primary and secondary gas jet distributors. By installing different functional modules on the primary and secondary gas jet distributors, a multi-functional modular gas jet snow removal vehicle with a rear-mounted functional assembly is formed. Multiple working modes can be formed through the combination of various functional modules to adapt to different operational scenarios.

[0018] (2) In this invention, the installation of different functional modules is realized by using a primary gas jet distributor and a secondary gas jet distributor, thereby realizing the independent operation requirements of each functional module, and also realizing the synergistic effects such as superposition, compensation and progression of operation efficiency through parameter adjustment between modules.

[0019] (3) In this invention, a two-stage distribution structure is formed by using a primary gas jet distributor and a secondary gas jet distributor. Simultaneously, a "Y"-shaped bifurcated gas diversion duct is used to equally divide and divert the gas jet generated by the engine nozzle, guiding it from both ends of the primary gas jet distributor into the inner cavity of the primary gas jet distributor, forming a ring-shaped topology. The jet gas is then distributed to the interior of the secondary gas jet distributor via a connector. This two-stage distribution structure not only rationally designs the gas jet inlet and diversion, reducing process damping losses, but also effectively regulates the direction and flow rate of the spiral airflow.

[0027] Combination Figure 1As shown, a rear-mounted gas jet snow removal vehicle includes a vehicle body and an aircraft engine 4. The vehicle body includes a front end and a cargo box 3, which are mounted on a chassis 8. The aircraft engine 4 is installed inside the cargo box 3, and an engine nozzle 14 is provided at the rear end of the aircraft engine 4. To meet the requirements of the functional assembly operating at the rear end of the equipment, the engine nozzle 14 is arranged in a rear-mounted layout. A primary gas jet distributor 5 and a secondary gas jet distributor 7 are sequentially installed on the rear axle of the chassis 8. The primary gas jet distributor 5 and the secondary gas jet distributor 7 are connected by a connector 9. The primary gas jet distributor 5 and the engine nozzle 14 are connected by a gas flow duct 13. The longitudinal direction of both the primary gas jet distributor 5 and the secondary gas jet distributor 7 is perpendicular to the forward direction of the vehicle body. Multiple first interfaces 6 are provided at the bottom of the primary gas jet distributor 5, and multiple second interfaces 11 are provided at the bottom of the secondary gas jet distributor 7.

[0028] Specifically, there are five first interfaces 6, each with an independent opening and closing structure. These interfaces 6 are used to connect to the snow blowing and de-icing functional modules. There are nine second interfaces 11, each with an independent opening and closing structure. These interfaces 11 are used to connect to the road drying functional module. The first interfaces 6 and the second interfaces 11 are standard interfaces for connecting to the operational functional modules, facilitating their connection. These operational functional modules include, but are not limited to, snow blowing, de-icing, and drying modules.

[0029] Combination Figure 1 As shown, in this embodiment, the gas diversion duct 13 has a "Y"-shaped bifurcation structure. The two outlet ends of the gas diversion duct 13 are respectively connected to the inlet pipe ports at both ends of the primary gas jet distributor 5. The gas diversion duct 13 is used to divert the gas jet generated by the engine nozzle 14 equally and enter the inner cavity of the primary gas jet distributor 5 from both ends. The "Y"-shaped bifurcation structure of the gas diversion duct 13 and the primary gas jet distributor 5 form a ring topology.

[0030] To ensure the structural stress distribution of the entire gas jet ice and snow removal vehicle, the aircraft engine 4 is centrally installed inside the vehicle body 3, and the centerline of the aircraft engine 4 is parallel to the forward direction of the vehicle body.

[0031] Combination Figure 1As shown, in this embodiment, the two ends of the secondary gas jet distributor 7 are telescopic structures. Specifically, the secondary gas jet distributor 7 has a three-section nested structure. The left and right sections are connected to the middle section through telescopic connectors 10, and the left and right sections can retract into the middle section. Through this structure, the secondary gas jet distributor 7 can extend to two expansion function module interfaces on each side. In addition, the vehicle body also includes a rear wheel set 12. In order to cooperate with the secondary gas jet distributor 7, the rear wheel sets 12 on both sides of the rear end of the vehicle body are connected to the rear axle of the chassis 8 through hydraulic telescopic structures, realizing the extension and retraction of the rear wheel sets 12. The hydraulic telescopic structure is a common structure in engineering machinery and is not shown in the figure, so it will not be described in detail here.

[0032] Combination Figure 1 and Figure 2 As shown, an air intake duct 15 is provided on the aircraft engine 4. The air intake duct 15 is a front-mounted structure installed at the front end of the aircraft engine 4. In order to increase the air intake effect of the air intake duct 15, the air intake duct 15 adopts an inverted U-shaped air intake with the side and roof of the vehicle.

[0033] The front of the vehicle is equipped with a driver's cab 1 and a fuel equipment room 2. The fuel equipment room 2 is located behind the driver's cab 1 and is used to provide fuel for the vehicle body and the aircraft engine 4.

[0034] Since the secondary gas jet distributor 7 is perpendicular to the rear axle of the chassis 8, in order to ensure the reliability of the installation of the secondary gas jet distributor 7 on the rear axle, a rear axle load-bearing connection support (not shown in the figure) is provided between the rear axle of the chassis 8 and the secondary gas jet distributor 7. The rear axle load-bearing connection support is used to support the secondary gas jet distributor 7.

[0035] Through the above structure, the entire gas jet snow removal vehicle is divided into three parts from front to back. The first part is the front of the vehicle, which consists of the cab 1 and the fuel equipment room 2; the second part is the cargo box 3, which houses the aircraft engine (4); and the third part is the primary gas jet distributor 5 and the secondary gas jet distributor 7. The three parts are connected by the chassis 8. Unlike other snow removal vehicles that have functional assemblies mounted on their undercarriages, this invention utilizes the primary gas jet distributor 5 and the secondary gas jet distributor 7 to connect functional modules to form a functional assembly, thus creating a gas jet snow removal vehicle with a rear-mounted multi-functional module combination. The functional modules include, but are not limited to, snow blowing modules, de-icing modules, and drying modules, which are combined and installed at the interlocking interfaces on the primary gas jet distributor 5 and the secondary gas jet distributor 7. The primary gas jet distributor 5 and the secondary gas jet distributor 7 form a modular gas jet distributor structure. The combined functional assembly mode is selected for matching operations according to the actual working scenario. In this invention, multiple functional modules are connected via the first interface 6 and the second interface 11 of the rear-mounted primary gas jet distributor 5 and secondary gas jet distributor 7. These functional modules include, but are not limited to, snow blowing, de-icing, and drying modules. Both the first interface 6 and the second interface 11 are independently openable, allowing each connected functional module to independently complete the tasks of breaking up, blowing away, and drying ice and snow within its designated area. Simultaneously, the functional modules can achieve synergistic effects through adaptive attitude control devices, enabling coordination, compensation, and superposition, thus forming a rich set of control strategies. Through this invention, the gas jet snow removal vehicle can transition from a single-module centralized operation mode to a distributed, collaborative operation mode involving multiple functional modules.

[0036] In this embodiment, a two-stage distribution structure is formed using a primary gas jet distributor 5 and a secondary gas jet distributor 7. Simultaneously, a Y-shaped bifurcated gas diversion duct 13 divides the gas jet generated by the engine nozzle 14 into equal portions, diverting it from both ends of the primary gas jet distributor 5 into the inner cavity of the primary gas jet distributor 5, forming a ring topology. The jet gas is then distributed to the interior of the secondary gas jet distributor via a connector 9, which is an independently opening and closing structure. This two-stage distribution structure not only rationally designs the gas jet inlet and diversion, reducing process damping losses, but also effectively regulates the direction and flow rate of the spiral airflow.

[0037] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
