Technical Field

[0001] The utility model relates to the technical field of engineering vehicles, in particular to a supercharging device and an operating vehicle. Background Art

[0002] At present, when engineering vehicles in related technologies are performing engineering operations, the pressure of the pressurized water provided is low due to the pressure loss caused by the operating height and pipelines, which affects the operating efficiency. Utility Model Content

[0003] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the utility model provides a boosting device.

[0005] A second aspect of an embodiment of the utility model provides a working vehicle.

[0006] In view of this, according to the first aspect of an embodiment of the utility model, a boosting device is provided, which is used for a working vehicle with a working compartment. The boosting device includes: a boosting module, which is arranged in the working compartment and is used to increase the pressure of a medium flowing through the boosting module; and a packaging component, which is covered on the outside of the boosting module.

[0007] The boosting device provided in the embodiment of the utility model includes a boosting module and a packaging component. Specifically, the working vehicle has a working compartment. It can be understood that when the working vehicle is used for engineering operations or fire rescue, the working compartment is generally used to accommodate staff or rescued persons.

[0008] The booster module can increase the pressure of the medium flowing through the booster module, thereby significantly improving the pressure output of the medium and ensuring operating efficiency.

[0009] Taking fire rescue as an example, it can be understood that the medium is a fire extinguishing medium. Specifically, since the boosting module can increase the pressure of the fire extinguishing medium flowing through the boosting module, the fire extinguishing medium sprayed by the equipment to be boosted connected to the boosting module can be fully atomized to form a high-pressure spray, and quickly absorb the heat in the fire scene to form water vapor, achieving the purpose of fire extinguishing through the effects of cooling and suffocation, greatly improving the efficiency of fire extinguishing, and after the fire is extinguished, there is basically no water stain left on the site, avoiding property losses to residents downstairs.

[0010] The equipment to be pressurized is an injection device or an external pipeline.

[0011] Optionally, the working vehicle further includes a boom system, and the working chamber is arranged on the boom system. That is, the working chamber can move with the movement of the boom system. When supplying water to a high-rise building, the boom system is unfolded and the working chamber is raised. It can be understood that the firefighters are located in the working chamber and use the pressurized equipment to perform firefighting operations.

[0012] Since the boosting module is located in the working chamber, that is, the boosting module is set on the side close to the equipment to be boosted, the pressure loss can be reduced, the pressure of the medium sprayed through the equipment to be boosted can be significantly increased, the atomization effect can be improved, the fire extinguishing range can be increased, and the fire extinguishing efficiency can be improved.

[0013] Among them, high-rise buildings refer to those with a building height of more than 24 meters.

[0014] The packaging cover is arranged on the outside of the boost module. On the one hand, it can prevent the workers or rescued persons from accidentally touching the parts of the boost module during the engineering operation or rescue process, which may cause the boost module to malfunction. The boost module is protected to ensure the smooth progress of the engineering operation.

[0015] On the other hand, it is understandable that some rescued persons are physically exhausted and have difficulty standing after being rescued. Therefore, the booster module encapsulated by the package can be used as a stool for staff or rescued persons to sit on, providing a more convenient and comfortable rescue method for the rescued persons.

[0017] In this technical solution, it is defined that the boost module includes a driving member and a first pump body. Specifically, the first pump body is connected to the driving member, and the first pump body is communicated with the injection device.

[0018] Specifically, under the drive of the driving member, the first pump body can start working, thereby pressurizing the medium entering the first pump body to increase the pressure of the medium, thereby enabling the medium sprayed out by the spraying device to be fully atomized, thereby improving the fire extinguishing effect.

[0019] In some technical solutions, optionally, the first pump body includes a plunger pump or a diaphragm pump; and / or the driving member includes a hydraulic motor or an electric motor.

[0020] In this technical solution, it is defined that the first pump body includes a plunger pump or a diaphragm pump, that is, the first pump body is a high-pressure pump, so as to realize pressurization of the medium flowing through the first pump body. Moreover, since the first pump body is a high-pressure pump, it is beneficial to make the pressure of the medium flowing through the first pump body reach above 4MPa, so that the medium is fully atomized to form a high-pressure spray, thereby improving the fire extinguishing efficiency and fire extinguishing effect.

[0021] The driving member includes a hydraulic motor or an electric motor, that is, the first pump body can be driven to work by the electric motor or the hydraulic motor. The specific configuration can be made according to actual needs.

[0022] In some technical schemes, optionally, the boosting module also includes a boosting pipeline and a pressure regulating valve, wherein one end of the boosting pipeline is connected to the liquid outlet end of the first pump body, and the other end of the boosting pipeline is connected to the injection device, and the pressure regulating valve is arranged on the boosting pipeline for adjusting the pressure of the medium in the boosting pipeline.

[0023] In this technical solution, it is defined that the boosting module also includes a boosting pipeline and a pressure regulating valve. Specifically, two ends of the boosting pipeline are respectively connected to the liquid outlet end of the first pump body and the injection device.

[0024] The pressure regulating valve is arranged on the boosting pipeline, and the pressure regulating valve can adjust the pressure of the medium in the boosting pipeline, so that the high-pressure medium after boosting can be sprayed out in atomization according to the adjusted pressure to ensure the fire extinguishing effect. For example, the pressure of the high-pressure medium after boosting can be adjusted to about 4MPa by the pressure regulating valve.

[0025] Optionally, the pressure regulating valve includes a first interface, a second interface and a third interface, wherein the first interface is connected to the liquid outlet end of the first pump body through a partial boosting pipeline, the second interface is connected to the injection device through a partial boosting pipeline, and the third interface is connected to the liquid inlet end of the first pump body through a pipeline.

[0026] Optionally, the boosting module also includes a pressure detection component, which is connected to the boosting pipeline. The pressure detection component can detect the pressure of the medium in the boosting pipeline, so that firefighters can adjust the pressure of the medium in the boosting pipeline through the pressure regulating valve according to the detection result of the pressure detection component.

[0027] Optionally, the pressure regulating valve includes a pressure regulating knob, which is exposed outside the packaging component, so that the pressure of the medium in the boosting pipeline can be manually adjusted according to the pressure value detected by the pressure detecting component.

[0028] Optionally, the pressure detection component includes a pressure gauge. It is understandable that the display screen of the pressure gauge is exposed outside the packaging component.

[0029] In some technical schemes, optionally, the boosting module also includes a safety valve and a pressure relief valve, wherein the first end of the safety valve is connected to the boosting pipeline between the liquid outlet end of the first pump body and the pressure regulating valve, the second end of the safety valve is connected to the liquid inlet end of the first pump body, and the pressure relief valve is connected to the boosting pipeline between the pressure regulating valve and the injection device.

[0030] In this technical solution, it is defined that the boosting module also includes a safety valve and a pressure relief valve. Specifically, the first end of the safety valve is connected to the boosting pipeline, and the first end of the safety valve is located between the liquid outlet of the first pump body and the pressure regulating valve.

By setting the safety valve, overflow can be performed in the event of a failure of the pressure regulating valve, the pressure in the boosting pipeline can be improved, the stable operation of the boosting device and the operating vehicle can be ensured, and rapid fire extinguishing can be achieved.

[0031] The pressure relief valve is connected to the boosting pipeline, and the pressure relief valve is located between the pressure regulating valve and the spray device. It is understandable that when firefighters are working on site, due to forgetting to install the spray gun or misoperation, the boosting device or the operating vehicle is started without installing the spray gun, and there is pressure in the boosting pipeline, which makes it impossible to install the spray gun smoothly. By setting up a pressure relief valve, the pressure in the boosting pipeline can be released, thereby ensuring the smooth installation of the spray gun and achieving timely fire extinguishing.

[0032] According to the second aspect of the utility model, a working vehicle is provided, comprising a supercharging device as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the supercharging device, which will not be described in detail here. Further, the working vehicle also includes a vehicle body and a working compartment, wherein the working compartment is arranged on the vehicle body, and the supercharging module is arranged in the working compartment.

[0034] In this technical solution, it is defined that the working vehicle further includes a liquid outlet pipeline, a second pump body and a spray device. Specifically, the liquid storage tank can store a medium. Optionally, the medium includes water, foam liquid and the like.

[0035] The liquid outlet pipeline includes a liquid inlet and a liquid outlet, wherein the liquid inlet is connected to the liquid storage tank, and the liquid outlet is connected to the boosting module. The second pump body is arranged on the liquid outlet pipeline. That is to say, when the second pump body is started, the medium in the liquid storage tank can be pumped from the liquid inlet to the liquid outlet, and after secondary boosting by the boosting module, it is sprayed out through the injection device to extinguish the fire.

[0036] By connecting the boosting module at the liquid outlet and performing secondary boosting on the medium pumped to the liquid outlet by the second pump body, the pressure output of the medium can be significantly improved. Specifically, the pressure of the medium can reach above 4 MPa, so that the medium sprayed out by the injection device can be fully atomized to form a high-pressure spray, thereby quickly absorbing the heat in the fire scene and forming water vapor, thereby achieving the purpose of extinguishing the fire through the effects of cooling and suffocation, greatly improving the fire extinguishing efficiency, and after the fire is extinguished, there is basically no water stain remaining on the site, avoiding property losses to residents downstairs.

[0037] Optionally, the working pressure of the second pump body is lower than the working pressure of the first pump body. That is to say, the second pump body only serves as a supply device and can operate at a low speed and stably for a long time. Compared with the use of a fire pump as a booster pump in the related technology, it can effectively improve the working stability and reliability of the second pump body, reduce the probability of failure of the second pump body, and extend the service life of the second pump body.

[0038] In addition, since the second pump body does not need to work under high pressure, it can effectively reduce the failure of the liquid outlet pipeline connected to the second pump body, such as leakage and deformation, and reduce the maintenance cost of the operating vehicle.

[0039] Optionally, the second pump body is a fire pump.

Specifically, the first guardrail and the second guardrail are adjacent and connected. It can be understood that the connection between the first guardrail and the second guardrail is the corner position of the working chamber.

[0042] The boosting module is arranged near the connection between the first guardrail and the second guardrail, that is, the boosting module is arranged near the corner of the working compartment, so that the boosting module avoids occupying more space in the working compartment as much as possible, while providing short rest facilities for the rescued persons, ensuring that the firefighters can successfully complete the rescue work.

[0044] In this technical solution, it is defined that the working vehicle also includes a boom system and a hydraulic system. Specifically, the boom system includes a plurality of booms, and specifically, the plurality of booms are movably connected. Optionally, the plurality of booms include telescopic booms or folding booms.

[0045] The hydraulic system is connected to the boom system, that is, the hydraulic system provides power to drive the multiple booms of the boom system to move, so that the multiple booms are in an extended state or a retracted state.

[0046] Optionally, the liquid outlet pipeline is connected to the arm system. The liquid outlet pipeline includes a telescopic pipeline, so that when the multiple arms are deployed or retracted, the telescopic pipeline can be telescoped along with the multiple arms.

[0047] When the driving member is a hydraulic motor, that is, when the first pump body is driven to work by the hydraulic motor, the hydraulic motor is connected to the hydraulic system, that is, the hydraulic motor is driven to work by the hydraulic system, that is, the hydraulic system of the working vehicle itself is used to drive the hydraulic motor to work, so that while achieving secondary pressurization of the medium flowing out of the liquid outlet, there is no need to provide a separate driving device to drive the first pump body, which is beneficial to simplifying the structure of the working vehicle while improving the fire extinguishing efficiency, reducing the number of parts of the working vehicle, and further reducing the production cost of the working vehicle.

[0048] The working chamber is arranged at one end of the boom system away from the vehicle body. Since the working chamber can accommodate firefighters, they can carry out firefighting operations in high-rise buildings when the boom system is in the unfolded state. In addition, the working chamber can also accommodate trapped persons in high-rise buildings where a fire occurs.

[0049] The boosting module is arranged in the working chamber, that is, the boosting module for secondary boosting of the medium is arranged in the working chamber to secondary boost the medium flowing out of the liquid outlet pipeline, thereby significantly increasing the pressure of the medium, improving the atomization effect, and thus improving the fire extinguishing efficiency.

[0050] Since the boosting module is encapsulated by a packaging component, some rescued persons are physically tired and have difficulty standing after being rescued. Therefore, the boosting module encapsulated by the packaging component can be used as a stool for firefighters or rescued persons to sit on, providing a more convenient and comfortable rescue method for the rescued persons.

[0051] In some technical schemes, optionally, the hydraulic system includes a hydraulic oil tank, an oil outlet pipe, an oil return pipe and a hydraulic pump, wherein the hydraulic oil tank is arranged on the vehicle body, the two ends of the oil outlet pipe are respectively connected to the oil outlet of the hydraulic oil tank and the hydraulic motor, the two ends of the oil return pipe are respectively connected to the oil return port of the hydraulic oil tank and the hydraulic motor, and the hydraulic pump is arranged on the oil outlet pipe; the working vehicle also includes a swivel joint, the swivel joint is arranged on the arm system, the liquid outlet pipeline, the oil outlet pipe and the oil return pipe respectively pass through the swivel joint, and can rotate relative to the swivel joint.

[0052] In this technical solution, it is defined that the hydraulic system includes a hydraulic oil tank, an oil outlet pipe, an oil return pipe and a hydraulic pump. Specifically, one end of the oil outlet pipe is connected to the oil outlet of the hydraulic oil tank, and the other end of the oil outlet pipe is connected to the hydraulic motor. Specifically, the other end of the oil outlet pipe is connected to the oil inlet joint of the hydraulic motor. It can be understood that the oil inlet joint is exposed to the packaging component.

[0053] One end of the oil return pipe is connected to the oil return port of the hydraulic oil tank, and the other end of the oil return pipe is connected to the hydraulic motor. Specifically, the other end of the oil return pipe is connected to the oil return port connector of the hydraulic motor. It can be understood that the oil return port connector is exposed to the packaging component.

[0054] The hydraulic pump is arranged on the oil outlet pipe. Specifically, under the action of the hydraulic pump, the hydraulic oil in the hydraulic oil tank enters the hydraulic motor through the oil outlet pipe and the oil inlet pipe joint, and then returns to the hydraulic oil tank through the oil return pipe joint and the oil return pipe of the hydraulic motor, so that the hydraulic motor can drive the first pump body to work, realize secondary pressurization of the medium flowing out of the liquid outlet, make the pressure of the medium reach above 4MPa, and spray out through the spray device in atomization, realize high-rise building fire extinguishing, increase the fire extinguishing range, and improve the fire extinguishing efficiency.

[0056] It is understandable that when firefighters are performing firefighting operations, the boom and the like will change their operating positions according to the situation. Since the liquid outlet pipeline, oil outlet pipeline and oil return pipeline can rotate relative to the swivel joint respectively, it is possible to avoid the liquid outlet pipeline, oil outlet pipeline and oil return pipeline twisting and tangling themselves during the movement or rotation of the boom and the like, thereby extending the service life of each pipeline and ensuring the smooth progress of the firefighting operation.

Specifically, the first end of the safety valve 128 is communicated with the boosting pipeline 125, and the first end of the safety valve 128 is located between the liquid outlet 124 of the first pump body 122 and the pressure regulating valve 127. The second end of the safety valve 128 is communicated with the liquid inlet 123 of the first pump body 122. By providing the safety valve 128, overflow can be performed in the event of a failure of the pressure regulating valve 127, thereby improving the pressure in the boosting pipeline 125, ensuring the stable operation of the boosting device 120 and the working vehicle 100, and realizing rapid fire extinguishing.

[0099] The pressure relief valve 129 is connected to the boosting pipeline 125, and the pressure relief valve 129 is located between the pressure regulating valve 127 and the spray device 112. It is understandable that when the firefighters perform on-site operations, due to forgetting to install the spray gun 113 or misoperation, the boosting device 120 or the working vehicle 100 is started without installing the spray gun 113, and there is pressure in the boosting pipeline 125, which makes it impossible to smoothly install the spray gun 113. By providing the pressure relief valve 129, the pressure in the boosting pipeline 125 can be released, thereby ensuring the smooth installation of the spray gun 113 and achieving timely fire extinguishing.

[0100] According to a second aspect of the present invention, a work vehicle 100 is provided, comprising a supercharging device 120 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the supercharging device 120, which will not be described in detail herein.

[0101] Furthermore, the working vehicle 100 further includes a vehicle body 110 and a working chamber 111 , wherein the working chamber 111 is disposed on the vehicle body 110 , and the boost module 220 is disposed in the working chamber 111 .

[0102] The boosting module 220 can increase the pressure of the medium flowing through the boosting module 220, thereby significantly improving the pressure output of the medium, so that the medium sprayed out by the boosting equipment to be connected to the boosting module 220 can be fully atomized to form a high-pressure spray, and quickly absorb the heat in the fire scene to form water vapor, thereby achieving the purpose of extinguishing the fire through the effects of cooling and suffocation, greatly improving the fire extinguishing efficiency, and after the fire is extinguished, there is basically no water stain remaining on the site, avoiding property losses to residents downstairs.

[0103] like Figure 1 As shown, in some embodiments, optionally, the vehicle body 110 is provided with a liquid storage tank 140, and the work vehicle 100 also includes a liquid outlet pipeline 150, a second pump body 160 and an injection device 112, wherein the liquid inlet 151 of the liquid outlet pipeline 150 is connected to the liquid storage tank 140, the liquid outlet 152 of the liquid outlet pipeline 150 is connected to the boosting module 220, the second pump body 160 is arranged on the liquid outlet pipeline 150, and the injection device 112 is connected to the boosting module 220.

[0104] In this embodiment, the working vehicle 100 is defined to further include a liquid outlet pipeline 150, a second pump body 160 and a spray device 112. Specifically, the liquid storage tank 140 can store a medium. Optionally, the medium includes water, foam liquid, and the like.

[0105] The liquid outlet pipeline 150 includes a liquid inlet 151 and a liquid outlet 152, wherein the liquid inlet 151 is connected to the liquid storage tank 140, and the liquid outlet 152 is connected to the boosting module 220. The second pump body 160 is arranged on the liquid outlet pipeline 150. That is to say, when the second pump body 160 is started, the medium in the liquid storage tank 140 can be pumped from the liquid inlet 151 to the liquid outlet 152, and after secondary boosting by the boosting module 220, it is sprayed out through the injection device 112 to extinguish the fire.

[0106] By connecting the boosting module 220 at the liquid outlet 152 and performing secondary boosting on the medium pumped to the liquid outlet 152 by the second pump body 160, the pressure output of the medium can be significantly improved. Specifically, the pressure of the medium can reach above 4 MPa, so that the medium sprayed by the injection device 112 can be fully atomized to form a high-pressure spray, thereby quickly absorbing the heat in the fire scene and forming water vapor, thereby achieving the purpose of extinguishing the fire through the effects of cooling and suffocation, greatly improving the fire extinguishing efficiency, and after the fire is extinguished, there is basically no water stain remaining on the site, avoiding property losses to residents downstairs.

[0107] Optionally, the working pressure of the second pump body 160 is lower than the working pressure of the first pump body 122. That is to say, the second pump body 160 only serves as a supply device and can operate at a low speed and stably for a long time. Compared with the use of a fire pump as a booster pump in the related art, it can effectively improve the working stability and reliability of the second pump body 160, reduce the probability of failure of the second pump body 160, and extend the service life of the second pump body 160.

[0108] In addition, since the second pump body 160 does not need to work under high pressure, it can effectively reduce the failure of the liquid outlet pipeline 150 connected to the second pump body 160 such as leakage and deformation, thereby reducing the maintenance cost of the work vehicle 100.

[0109] Optionally, the second pump body 160 is a fire pump.

[0110] like Figure 1 As shown, in some embodiments, optionally, the work chamber 111 includes adjacent first guardrail 115 and second guardrail 116 , the first guardrail 115 and the second guardrail 116 are connected, and the boost module 220 is arranged near the connection between the first guardrail 115 and the second guardrail 116 .

[0111] In this embodiment, the working chamber 111 is defined to include a first guardrail 115 and a second guardrail 116. Specifically, the first guardrail 115 and the second guardrail 116 are adjacent and connected. It can be understood that the connection between the first guardrail 115 and the second guardrail 116 is the corner position of the working chamber 111.

[0112] The boosting module 220 is arranged near the connection between the first guardrail 115 and the second guardrail 116, that is, the boosting module 220 is arranged near the corner of the working chamber 111, so that the boosting module 220 avoids occupying more space in the working chamber 111 as much as possible, while providing a short rest facility for the rescued persons, ensuring that the firefighters can successfully complete the rescue work.

[0113] like Figure 5 As shown, in some embodiments, optionally, the work vehicle 100 also includes a boom system and a hydraulic system 170, wherein the boom system is arranged on the vehicle body 110, the boom system includes multiple booms, the multiple booms are movably connected, the working compartment 111 is arranged at one end of the boom system away from the vehicle body 110, the hydraulic system 170 is arranged on the vehicle body 110 and connected to the boom system, the hydraulic system 170 can drive at least one boom to move relative to the remaining booms so that the multiple booms can be deployed or retracted; when the driving component 121 of the boosting module 220 includes a hydraulic motor, the hydraulic motor is connected to the hydraulic system 170.

[0114] In this embodiment, it is defined that the working vehicle 100 further includes a boom system and a hydraulic system 170. Specifically, the boom system includes a plurality of booms, and specifically, the plurality of booms are movably connected. Optionally, the plurality of booms include telescopic booms or folding booms.

[0115] The hydraulic system 170 is connected to the boom system, that is, the hydraulic system 170 provides power to drive the multiple booms of the boom system to move, so that the multiple booms are in an extended state or a retracted state.

[0116] Optionally, the liquid outlet pipeline 150 is connected to the boom system. The liquid outlet pipeline 150 includes a telescopic pipeline 230, so that when the multiple booms are deployed or retracted, the telescopic pipeline 230 can be telescoped along with the multiple booms.

[0117] When the driving member 121 is a hydraulic motor, that is, when the first pump body 122 is driven by the hydraulic motor, the hydraulic motor is connected to the hydraulic system 170, that is, the hydraulic motor is driven by the hydraulic system 170, that is, the hydraulic system 170 of the working vehicle 100 itself is used to drive the hydraulic motor to work, so that the medium flowing out from the liquid outlet 152 can be pressurized twice without the need to provide a separate driving device to drive the first pump body 122, which is beneficial to simplifying the structure of the working vehicle 100 while improving the fire extinguishing efficiency, reducing the number of parts of the working vehicle 100, and further reducing the production cost of the working vehicle 100.

[0118] The working compartment 111 is arranged at one end of the boom system away from the vehicle body 110. Since the working compartment 111 can accommodate firefighters, the firefighters can perform firefighting operations in high-rise buildings when the boom system is in the unfolded state. In addition, the working compartment 111 can also accommodate trapped people in a high-rise building where a fire occurs.

[0119] The boosting module 220 is arranged in the working chamber 111, that is, the boosting module 220 for secondary boosting of the medium is arranged in the working chamber 111 to secondary boost the medium flowing out of the liquid outlet pipeline 150, significantly increase the pressure of the medium, improve the atomization effect, and thus improve the fire extinguishing efficiency.

[0120] Since the boosting module 220 is encapsulated by the encapsulation member 130, some rescued persons are physically exhausted and have difficulty standing after being rescued. Therefore, the boosting module 220 encapsulated by the encapsulation member 130 can be used as a stool for firefighters or rescued persons to sit on, providing a more convenient and comfortable rescue method for the rescued persons.

[0121] like Figure 5 As shown, in some embodiments, optionally, the hydraulic system 170 includes a hydraulic oil tank 171, an oil outlet pipe 172, an oil return pipe 173 and a hydraulic pump 174, wherein the hydraulic oil tank 171 is arranged on the vehicle body 110, the two ends of the oil outlet pipe 172 are respectively connected to the oil outlet port 175 of the hydraulic oil tank 171 and the hydraulic motor, the two ends of the oil return pipe 173 are respectively connected to the oil return port 176 of the hydraulic oil tank 171 and the hydraulic motor, and the hydraulic pump 174 is arranged on the oil outlet pipe 172.

[0122] In this embodiment, the hydraulic system 170 is defined to include a hydraulic oil tank 171, an oil outlet pipe 172, an oil return pipe 173, and a hydraulic pump 174. Specifically, one end of the oil outlet pipe 172 is connected to an oil outlet 175 of the hydraulic oil tank 171, and the other end of the oil outlet pipe 172 is connected to a hydraulic motor. Specifically, the other end of the oil outlet pipe 172 is connected to an oil inlet joint 190 of the hydraulic motor. It is understood that the oil inlet joint 190 is exposed to the packaging component 130.

[0123] One end of the oil return pipe 173 is connected to the oil return port 176 of the hydraulic oil tank 171, and the other end of the oil return pipe 173 is connected to the hydraulic motor. Specifically, the other end of the oil return pipe 173 is connected to the oil return port connector 210 of the hydraulic motor. It can be understood that the oil return port connector 210 is exposed to the packaging member 130.

[0124] The hydraulic pump 174 is arranged on the oil outlet pipe 172. Specifically, under the action of the hydraulic pump 174, the hydraulic oil in the hydraulic oil tank 171 enters the hydraulic motor through the oil outlet pipe 172 and the oil inlet pipe joint, and then returns to the hydraulic oil tank 171 through the oil return pipe 173 joint and the oil return pipe 173 of the hydraulic motor, so that the hydraulic motor can drive the first pump body 122 to work, realize the secondary pressurization of the medium flowing out from the liquid outlet 152, so that the pressure of the medium reaches more than 4MPa, and is sprayed out through the spray device 112 in an atomized manner, so as to realize the fire extinguishing of high-rise buildings, increase the fire extinguishing range, and improve the fire extinguishing efficiency.

[0125] like Figure 5 As shown, in some embodiments, optionally, the work vehicle 100 also includes a swivel joint 180, which is arranged on the boom system, and the liquid outlet pipeline 150, the oil outlet pipe 172 and the oil return pipe 173 respectively pass through the swivel joint 180 and can rotate relative to the swivel joint 180.

[0126] In this embodiment, it is defined that the working vehicle 100 further includes a swivel joint 180. Specifically, the swivel joint 180 is disposed on the boom system.

[0127] The liquid outlet pipeline 150, the oil outlet pipe 172 and the oil return pipe 173 pass through the swivel joint 180 respectively, that is, the liquid outlet pipeline 150, the oil outlet pipe 172 and the oil return pipe 173 are fixed to the boom system through the swivel joint 180 to install and fix the liquid outlet pipeline 150, the oil outlet pipe 172 and the oil return pipe 173.

[0128] It is understandable that when firefighters are performing firefighting operations, the boom and the like will change their operating positions according to the situation. Since the liquid outlet pipeline 150, the oil outlet pipe 172 and the oil return pipe 173 can rotate relative to the swivel joint 180, respectively, it is possible to avoid the liquid outlet pipeline 150, the oil outlet pipe 172 and the oil return pipe 173 twisting and tangling themselves during the movement or rotation of the boom and the like, thereby extending the service life of each pipeline and ensuring the smooth progress of the firefighting operation.

[0129] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the spray device 112 includes a spray gun 113 and a reel 114 , wherein the reel 114 is connected to the spray gun 113 and the boost module 220 .

[0130] In this embodiment, the injection device 112 is defined to include a spray gun 113 and a reel 114. Specifically, the reel 114 is connected to the spray gun 113 and the boost module 220. That is, the boost module 220 is connected to the spray gun 113 through the reel 114. That is, the high-pressure medium after secondary pressurization by the boost module 220 flows through the reel 114 and is atomized and sprayed out through the spray gun 113 to form a high-pressure spray, which quickly absorbs the heat in the fire scene and forms water vapor, thereby achieving the effect of cooling and suffocation, thereby improving the fire extinguishing effect.

[0131] By arranging the reel 114 between the booster module 220 and the spray gun 113, it is convenient for firefighters to select a suitable fire extinguishing position according to the actual fire extinguishing scene and to move firefighters, that is, it is convenient for firefighters to carry out firefighting operations and further improve fire extinguishing efficiency.

[0132] Optionally, the boost module 220 is further provided with a quick-connect port 240 , which is exposed outside the packaging component 130 , and the reel 114 is connected to the boost module 220 via the quick-connect port 240 .

[0133] In some embodiments, optionally, the work vehicle 100 includes a fire truck.

[0134] Optionally, the fire truck comprises a fire-lift truck.

[0135] In a specific embodiment, the main structure of the high-pressure spray module (boosting device 120) is that the hydraulic oil enters the hydraulic motor (drive member 121) through the hydraulic P-port connector (oil inlet connector 190), and then returns to the hydraulic oil tank 171 through the hydraulic T-port connector (oil return connector 210). The hydraulic motor drives the plunger pump (first pump body 122) to perform secondary boosting on the low-pressure water in the water outlet pipeline (liquid outlet pipeline 150) to make the water pressure reach above 4 MPa. After passing through the safety valve 128 and the pressure regulating valve 127, the high-pressure water is transported to the water hose reel (reel 114) through the water channel quick connector, and finally the water is converted into high-pressure spray through the high-pressure spray gun (spray gun 113), which quickly absorbs the heat in the fire scene and forms water vapor, thereby achieving the effect of cooling and suffocation to realize fire extinguishing in high-rise buildings.

[0136] To facilitate the installation and protection of the high-pressure spray module, the booster module box (package 130) packages the booster module 220. After packaging, the booster module 220 is installed in the work bucket (working chamber 111), which can provide two people with a seat. Some trapped persons may feel tired and have difficulty standing after being rescued, so they can sit on the module box (package 130), providing a more convenient and comfortable rescue method for the rescued persons.

[0137] The fire pump (second pump body 160) of the aerial fire truck (operating vehicle 100) only serves as a high-rise water source supply device, and can operate stably at a low speed for a long time. The water source provided only needs to overcome the pressure loss caused by the water supply height. A high-pressure spray module (boosting device 120) is provided on the working bucket (working chamber 111) at the end of the boom. The hydraulic system 170 of the aerial fire truck itself is used to provide power, and the water source is pressurized for a second time to achieve a pressure water output of ≥4MPa, and the water is atomized, which greatly improves the fire extinguishing efficiency of the water. After the fire is extinguished, there is basically no water stain remaining on the site, avoiding property damage to the downstairs.
