[0035] DETAILED DESCRIPTION

[0036] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the following specific embodiments.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "formed", "installed", "provided with", "set", "connected", etc. should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate connector, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the present invention, unless otherwise specified, the directions or positional relationships indicated by the directional words "front", "back", "up", "down", "left" and "right" are directions indicated by the coordinate system based on the normal travel of the rescue machinery. For example, the front of the rescue machinery when it is traveling normally is "front", the left hand side of the operator when facing the front is "left", and the right hand side is "right".

[0039] It should be noted that in the following description, the rear end of the engine refers to the flywheel end of the engine (i.e., the power output end), and the front end of the engine refers to the end opposite to the rear end of the engine. Figure 1 The engine 101 is shown in the figure, and the front end of the engine 101 is the right side of the platform 400 (i.e. Figure 1 The rear end of the engine 101 is the left side of the platform 400 (ie Figure 1 as indicated).

[0040] The present invention provides a modular power system, combining Figure 1 and Figure 2 As a specific embodiment, the modular power system of the present invention is installed on a platform 400, and is divided into an engine assembly module 100, a radiator assembly module 200 and a fuel tank assembly module 300 based on the three heaviest and largest main components (engine, radiator and fuel tank) in the power system, see Figure 1 and Figure 3 The engine assembly module 100 is arranged at the rear side of the platform 400, and includes an engine 101 as the main body of the engine assembly module 100, and the engine 101 is arranged in a horizontal manner (the front and rear ends of the engine 101 are arranged along the left and right directions of the platform 400); see Figure 1 and Figure 8 , the radiator assembly module 200 is located at the front end of the engine 101, and includes a radiator 201 as the main body of the radiator assembly module 200; see Figure 1 and Fig.10The fuel tank assembly module 300 is located in front of the engine assembly module 100 and the radiator assembly module 200, and includes a fuel tank 301 as the main body of the fuel tank assembly module 300. When carrying out rescue and disaster relief tasks, the three modules can be disassembled and transported in modular form so that they can be quickly placed in the disaster-stricken area and quickly assembled on site. The horizontally placed engine 101 can be arranged closer to the rear side of the vehicle body as a whole, that is, the engine 101 can be arranged on the rear side of the platform 400, so that its support point can coincide with the rear edge of the platform 400, thereby improving the space utilization rate of the whole machine, reducing the size of the whole machine platform, reducing the weight of the platform, and reducing the cost; and because the engine 101 is arranged at the rear, the center of mass of the engine assembly module 100 with the engine 101 as the main body is closer to the rear side of the vehicle body, and the weight of the engine assembly module 100 can play a counterweight role, thereby reducing the counterweight or directly canceling the counterweight, realizing the lightweight of the whole machine, further reducing the cost, and being more conducive to transportation. It should be noted that, preferably, the intervals between the engine assembly module 100, the radiator assembly module 200 and the fuel tank assembly module 300 should be small enough to meet the requirements of the engine 101 being able to run smoothly, so that the size of the platform 400 can be further reduced. In order to improve the modularity of the power system, its fuel system also needs to be modularized. As a specific embodiment of the modular power system of the present invention, the fuel system is divided according to three major assembly modules, wherein the engine assembly module 100 includes an engine fuel system, the radiator assembly module 200 includes a radiator fuel system, and the fuel tank assembly module 300 includes a fuel tank fuel system. The three fuel systems are directly integrated on their respective assembly modules, so that the pipelines of the fuel system do not need to be fixed on the platform. In order to facilitate the disassembly, transportation and assembly of the whole machine, the engine fuel system, the radiator fuel system and the fuel tank fuel system quick-change joints are connected in sequence through a quick-change device.

[0041] Specifically, see Figure 3 , Fig. 9 and Fig.10The engine fuel system includes a fuel filter 104, a fuel electronic pump 105 and an engine fuel pipeline 106, the radiator fuel system includes a fuel radiator 213 and a radiator fuel pipeline 212, the fuel tank fuel system includes an oil-water separator 302, a fuel tank fuel pipeline 303 and a fuel cut-off valve 304, and the quick-change device is a quick-change joint or a spring clamp. It should be noted that the quick-change devices connecting the three fuel systems can all be quick-change connectors. For example, the engine fuel system includes an engine fuel line quick-change connector 107, and the radiator fuel system includes a radiator fuel line quick-change connector 211. The engine fuel line quick-change connector 107 is matched and connected with the radiator fuel line quick-change connector 211, and the quick-change connector is provided in two pairs, so as to be able to connect the engine fuel system and the radiator fuel system to realize the oil supply and oil return between the two. The quick-change connector connecting the radiator fuel line and the fuel tank fuel system has the same structure as the quick-change connector provided between the above-mentioned engine fuel system and the radiator fuel system, and is also provided with two pairs, so as to realize the oil supply and oil return between the radiator fuel system and the fuel tank fuel system. The quick-change devices connecting the three fuel systems can also all or partly be spring clamps. For example, the quick-change connector provided between the radiator fuel system and the fuel tank fuel system can be replaced with a spring clamp. For details, see Fig. 9 The radiator fuel system includes a radiator fuel line spring clamp 218, which is quickly connected to the fuel line 303 of the fuel tank, and two pairs of radiator fuel line spring clamps 218 are provided to connect the radiator fuel system and the fuel tank fuel system to conduct oil inlet and outlet between the two. In addition, in order to better understand the connection relationship between the various fuel systems, see Fig.12 , Fig.12The arrow lines in each fuel system correspond to their respective fuel lines. For example, the arrow line in the engine fuel system corresponds to the engine fuel line 106. The fuel outlet of the fuel tank 301 is connected to the oil cut-off valve 304 and the oil-water separator 302 through the fuel tank fuel line 303, so that the fuel is delivered to the radiator fuel system, and directly delivered to the engine fuel system through the radiator fuel line 212, so that the fuel passes through the fuel electronic pump 105 and the fuel filter 104 in sequence and enters the fuel inlet of the engine 101. The fuel passing through the fuel filter 104 will have a part of the fuel return. A three-way joint 119 is provided on the engine fuel pipeline 106, so that the oil return port of the engine 101 and the oil return port of the fuel filter 104 are connected to a common oil return pipeline. The oil return pipeline only needs to be provided with a pair of quick-change joints to realize the oil return from the engine fuel system to the radiator fuel system, thereby reducing the number of quick-change joints and pipelines, facilitating modular rapid disassembly and assembly, and the fuel returned from the engine fuel system enters the oil inlet of the fuel radiator 213 for heat dissipation. After heat dissipation, the fuel flows from the oil outlet of the fuel radiator 213 to the oil inlet of the fuel tank 301 to realize fuel recovery.

[0042] It should be noted that in order to enable the arrangement between the engine 101 and the radiator 201 to be arranged separately and flexibly independently without being restricted by the fan 206, the modular power system of the present invention cancels the heat dissipation scheme of the engine driving the fan, and the fan 206 of the radiator assembly module 200 is driven by the hydraulic motor 205 to form an independent heat dissipation system, thereby improving the modularity of the engine assembly module 100 and the radiator assembly module 200.

[0043] The power system also includes an air conditioning system, and the core components of the air conditioning system must be installed on different components. The compressor is installed on the engine, the condenser is installed in the radiator, and the evaporator is installed in the cab. In order to realize modular disassembly, the air conditioning system can be quickly installed and separated. As a specific embodiment of the modular power system of the present invention, see Figure 3 , Figure 4 and Fig. 9The engine assembly module 100 includes an engine warm water pipeline 109 connected to the water outlet and the water inlet of the engine 101, an engine warm water pipeline quick-change joint 108, a compressor 113, an engine refrigerant pipe 115 connected to the compressor 113, and an engine refrigerant pipe quick-change joint 116. The radiator assembly module 200 includes a condenser assembly 208, a radiator refrigerant pipe 209, a first radiator warm water pipeline quick-change joint 210, a liquid storage tank 214, and a second radiator warm water pipeline quick-change joint 216 for connecting the evaporator. Radiator warm water pipe quick-change joint 215, radiator refrigerant pipe quick-change joint 216 for connecting the evaporator and radiator warm water pipe 217, wherein the engine warm water pipe 109 is connected to the first radiator warm water pipe quick-change joint 210 through the engine warm water pipe quick-change joint 108 to achieve connection with the radiator warm water pipe 217, and the high-temperature coolant of the engine 101 flows from the water outlet of the engine 101 through the water outlet of the engine warm water pipe 109 to the radiator warm water pipe The cooling liquid flows through the radiator warm water pipe 217 to the evaporator in the cab to achieve the heating purpose of the air conditioning system. The cooling liquid after heat exchange flows back to the radiator warm water pipe 217, and flows back to the water inlet of the engine 101 through the water inlet pipe of the engine warm water pipe 109 to regenerate high-temperature cooling liquid. The engine refrigerant pipe 115 is connected to the evaporator and condenser assembly 208 respectively through the engine refrigerant pipe quick-change joint 116. The compressor 113 is installed on the engine 101 through the compressor drive belt 112 and the compressor installation tensioning mechanism 114. The engine 101 drives the compressor 113 to run. The refrigerant is connected to the condenser assembly 208 from the refrigerant outlet of the compressor 113 through the refrigerant output pipeline of the engine refrigerant pipe 115, and then flows to the liquid storage tank 214 through the radiator refrigerant pipe 209, thereby flowing to the evaporator in the cab to achieve the cooling purpose. The refrigerant after heat exchange in the evaporator flows back to the refrigerant inlet of the compressor 113 through the refrigerant input pipeline of the engine refrigerant pipe 115 for circulating refrigeration. The air-conditioning system realizes rapid disconnection and connection of the pipes between the modules according to the different modules integrated with the compressor 113 and the condenser assembly 208 through quick-change connectors, thereby ensuring the convenience of disassembly and assembly between the modules of the modular power system of the present invention. The core components of the air-conditioning system, the compressor 113 and the condenser assembly 208, are both as close to one side of the platform as possible to facilitate later maintenance or replacement of core components.

[0044] It should be noted that the quick-change connectors connecting the various pipes in the fuel system and the air-conditioning system in the above technical solution are divided into male connectors and female connectors. For example, the engine fuel pipe quick-change connector 107 and the radiator fuel pipe quick-change connector 211 are matching male connectors and female connectors, and the engine warm water pipe quick-change connector 108 and the first radiator warm water pipe quick-change connector 210 are matching male connectors and female connectors. When the male connector and the female connector cooperate, the pipes are connected, and the pipes are automatically sealed when they are pulled out. They have the characteristics of quick plugging and unplugging and self-sealing. When repairing the engine 101, parts in the fuel system or parts in the air-conditioning system, disconnecting the quick-change connector can avoid leakage of the medium (fuel, coolant, refrigerant) in the pipes, facilitate repair and replacement, and reduce the loss of the medium in the pipes.

[0045] It should also be noted that the pipe connections between the modules of the engine assembly module 100, the radiator assembly module 200 and the fuel tank assembly module 300 are connected by a quick-change device. Preferably, the pipes inside each module can also be connected by a quick-change device. When mechanical damage occurs at the rescue site, the pipes connected to the damaged parts can be quickly plugged in and out to facilitate the repair and replacement of the parts, so that rescue work can be quickly carried out after the repair. Preferably, the quick-change device uses a quick-change connector.

[0046] As a preferred embodiment of the modular power system of the present invention, see Figure 5-7 The engine assembly module 100 includes an engine bracket 103 for mounting the engine 101 and an integrated shock absorber 117 mounted between the engine bracket 103 and the engine support 401 on the platform 400. The integrated shock absorber 117 has a mounting portion 117b embedded in a mounting hole of the engine support 401. A first mounting plate 117c is provided between the mounting portion 117b and the rubber pad 117a. The integrated shock absorber 117 is fixed to the first mounting hole 117e on the first mounting plate 117c by bolts passing through the first mounting hole 117e on the first mounting plate 117c. 17 is installed on the engine support 401 in advance, a second mounting plate 117d is provided on the upper surface of the rubber pad 117a, a second mounting hole 117f is provided on the second mounting plate 117d, and an engine mounting bolt 118 is threadedly matched with the second mounting hole 117f. When installing or disassembling the engine assembly module 101, only the engine mounting bolt 118 needs to be installed or removed to separate the engine 103 from the engine support 401, without complicated clamping installation, which greatly saves the installation and disassembly time of the engine module.

[0047] As a specific implementation of the modular power system of the present invention, see Figure 8The radiator assembly module 200 also includes a radiator pipeline 202, an auxiliary water tank 203 and a water supply pipe 207. The auxiliary water tank 203 is arranged on the top of the radiator 201. The auxiliary water tank 203 is connected to the engine water return pipe of the radiator pipeline 202 through the water supply pipe 207. Since the auxiliary water tank 203 is located at a higher position, under the action of gravity, when the engine 101 is short of coolant, the coolant inside the auxiliary water tank 203 will flow through the water supply pipe 207 to the engine water return pipe of the radiator pipeline 202 for water supply, ensuring that the engine 101 has sufficient coolant inside, providing a guarantee for the stable operation of the engine 101. The water supply pipe 207 and the auxiliary water tank 203 are both fixed on the radiator 201, becoming a part of the radiator assembly module 200, which is convenient for modular transportation.

[0048] As a preferred embodiment of the modular power system of the present invention, see Figure 1 and Fig.11 The front end of the radiator 201 close to the platform 400 extends out of the lateral side of the engine 101 ( Fig.11 and Figure 1 The rear side wall of the fuel tank 301 is located on the lateral side of the engine 101 and is close to the radiator 201. The part is offset relative to the engine 101 toward the front of the platform 400 to form an offset space that can accommodate the extended end of the radiator 201, and the rear side wall of the fuel tank 301 is formed with a guide side wall that can guide part of the heat dissipation airflow passing through the extended end of the radiator 201 to the lateral side of the engine 101. When the engine 101 is in operation, a large amount of heat will be generated. The fan 206 on the side of the radiator 201 close to the engine 101 will generate a heat dissipation airflow from the front end of the engine 101 to the rear end of the engine 101. To take away the heat, and due to the setting of the guide side wall, the heat dissipation airflow at the extended end of the radiator 201 is partially blown to the guide side wall, and after contacting the guide side wall, the original airflow direction will be changed, and it will continue to move forward along the extension direction of the guide side wall. The extension direction of the guide side wall points to the lateral side of the engine 101, so that the heat dissipation airflow of this part is blown to the heat emitted from the lateral side of the engine 101, thereby improving the heat dissipation efficiency of the engine 101. The rear side wall of the fuel tank 301 can replace the power compartment partition, and there is no need to set up an additional partition at this position to block the high temperature heat dissipation airflow, which simplifies the structure, reduces the cost, and also makes the whole machine more modular and the assembly and disassembly speed faster. In the preferred case, a heat insulation layer is set on the outer wall of the fuel tank 301, and the heat insulation layer is a heat insulation sponge to avoid the excessively high temperature of the heat dissipation airflow from causing adverse effects on the fuel tank 301, thereby enhancing the safety performance of the fuel tank 301.

[0049] Specifically, see Fig.11The fuel tank 301 includes a first tank body 301a and a second tank body 301b which are connected to each other. The first tank body 301a is located on the lateral side of the engine 101, and the second tank body 301b is located on the front side of the radiator 201. The rear side wall of the second tank body 301b is offset front-to-back from the rear side wall of the first tank body 301a, and the rear side wall of the second tank body 301b is connected to the rear side wall of the first tank body 301a through an inclined side wall 301c, and the inclined side wall 301c is a guide side wall.

[0050] As a specific implementation of the modular power system of the present invention, see Fig.10 The fuel tank assembly module 300 includes an air filter 305, a filter 306 and an intake pipe 307. The filter 306 is installed at the air inlet of the air filter 305 to replace the air pre-filter for preliminary filtering of the air. The structure is simpler and the cost is reduced. The filter 306 occupies a small volume, which is conducive to modularization and convenient disassembly and assembly. The air filter 305 is connected to the air inlet of the engine 101 through the intake pipe 307 to transport the filtered air to the engine 101 to ensure the smooth operation of the engine 101.

[0051] It should be noted that in order to improve the modularity of the modular power system of the present invention, see Figure 3 The engine assembly module 100 also integrates a transmission system 102, an exhaust tail pipe 110 and a post-processor assembly 111. For ease of installation, the engine 101 preferably uses an engine with an integrated post-processor assembly to meet emission standards; see Figure 8 A fan guard and a motor bracket assembly 204 are installed on the radiator 201 to protect the fan 206, and a hydraulic motor 205 is installed on the motor bracket so that it can drive the fan 206 to operate.

[0052] It should also be noted that in addition to the piping layout of the fuel system and the air-conditioning system, the modular power system of the present invention also integrates other piping and electrical circuits on each module, such as the piping layout of the hydraulic motor 205 and the circuits of the electrical components of the engine 101. In order to facilitate the installation and disassembly of the pipelines, the hydraulic pipelines are connected by quick-change devices, and the electrical circuits can be connected to other modules by directly installing plugs at the required positions of the modules.

[0053] The modular power system of the present invention is based on the three heaviest and largest main components (engine 101, radiator 201 and fuel tank 301), and divides the power system into engine assembly module 100, radiator assembly module 200 and fuel tank assembly module 300, so as to realize the modularization of the power system. When performing rescue machinery disaster relief tasks, it can be modularly disassembled and assembled quickly for easy transportation. The independent heat dissipation system solution in which the hydraulic motor 205 drives the fan 206 is adopted, so that the transversely placed engine 101 can be arranged closer to the rear side of the vehicle body, so as to make the structure more compact, improve the space utilization of the whole machine, reduce the overall size of the platform 400, and reduce the weight and cost. The rear placement of the engine 101 makes the center of mass of the engine module 100 backward, so that the counterweight can be reduced or eliminated, so as to realize the lightweight of the whole machine and be more conducive to transportation. The engine 101 is closer to the rear side of the platform 400, which is also convenient for subsequent repair and maintenance. At the same time, the fuel system is divided into three parts: the engine fuel system, the radiator fuel system and the fuel tank fuel system, which are directly integrated into the three assembly modules, and each is connected to each other through a quick-change device, which improves the modularity of the power system and makes the disassembly, transportation, assembly, maintenance and replacement of the whole machine more convenient. In addition, the air-conditioning system is divided according to the modules to be integrated into the modules of the power system, and the quick disconnection and connection of the pipelines between the modules are realized through the quick-change joints to ensure the convenience of disassembly and assembly of the air-conditioning system pipelines between the modules. In addition, the arrangement of the fuel tank 301 is special, and the rear side wall of the fuel tank 301 can replace the power compartment partition, simplifying the structure, and improving the heat dissipation efficiency of the engine 101, while also reducing costs and improving the modularity.
