Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, and more specifically, to a fire protection device. Background Technology

[0002] Currently, the main technical parameters of a long-span high-pressure water cannon fire truck include the boom working height and the total liquid load capacity. It's understandable that the boom weight is positively correlated with the boom working height; that is, the higher the boom, the heavier it is. Similarly, the lower the boom height, the lighter it is.

[0003] High-pressure water cannon fire trucks in related technologies integrate the boom and liquid tank into a single vehicle. Because the overall vehicle weight and axle load must comply with regulations, meaning they cannot exceed the chassis's permissible weight, achieving a higher boom working height requires sacrificing the liquid tank's capacity; conversely, increasing the liquid tank's capacity requires sacrificing the boom's working height.

[0004] In other words, the high-pressure water jet fire trucks in the relevant technologies cannot simultaneously optimize both the boom working height and the total liquid load of the vehicle. Summary of the Invention

[0005] The embodiments of the present invention are intended to at least solve one of the technical problems existing in the prior art.

[0006] Therefore, a first aspect of the embodiments of the present invention provides a fire-fighting device.

[0007] In view of the above, according to a first aspect of the present invention, a fire-fighting device is provided, the fire-fighting device comprising: at least two vehicle bodies, the at least two vehicle bodies including a first vehicle body and a second vehicle body, the first vehicle body being provided with a boom system, the second vehicle body being provided with a first storage container for containing fire extinguishing medium; and a spraying assembly disposed on the boom system and capable of communicating with the first storage container.

[0008] The fire-fighting equipment provided in this embodiment of the invention includes at least two vehicle bodies and a spraying assembly. Specifically, the at least two vehicle bodies include a first vehicle body and a second vehicle body. The first vehicle body is equipped with a boom system. It is understood that the boom system includes multiple movable booms. Any one of the multiple movable booms can move relative to the remaining movable booms to extend or retract at least one movable boom.

[0009] Optionally, the multiple booms may include multiple folding arms, meaning that any folding arm can be folded relative to the others. Alternatively, the multiple booms may include multiple telescopic arms, meaning that any telescopic arm can extend or retract relative to the others. Or, the multiple booms may include at least one telescopic arm and at least one folding arm. The specific configuration can be tailored to actual needs.

[0010] The spraying assembly is mounted on the boom system. Optionally, the spraying assembly includes a connected spraying pipe and a nozzle. The spraying pipe is mounted on multiple movable booms, and can move the spraying pipe during the extension or retraction of the multiple movable booms. The spraying pipe can communicate with the first storage container, and the nozzle is mounted on at least one movable boom. Specifically, during firefighting operations (water spraying operations), the extinguishing medium in the first storage container is sprayed out through the nozzle after passing through the spraying pipe.

[0011] Understandably, large-span high-pressure firefighting equipment mainly includes a chassis system, boom system, support system, water system, and electrical-hydraulic system. Its main technical parameters include boom working height, total vehicle fluid capacity, and other parameters.

[0012] Because the overall vehicle weight and axle weight must comply with regulations, meaning they cannot exceed the chassis's permissible weight, and this can be understood as chassis permissible weight = boom weight + fluid load + other component weight, it's impossible for high-pressure water cannon fire trucks in related technologies to simultaneously achieve optimal boom working height and fluid load.

[0013] The second vehicle body is equipped with a first material storage unit, and the injection assembly can communicate with the first material storage unit. In other words, the boom system and the first material storage unit are set on two different vehicle bodies. That is, the first vehicle body is equipped with the boom system but not with the liquid storage device, so that most of the weight can be distributed to the boom system. That is, under the premise of the same vehicle chassis, the boom system can be made higher without exceeding the weight limit.

[0014] In other words, while ensuring that the first vehicle body meets the overall vehicle weight requirements, the weight of the boom system on the first vehicle body is increased as much as possible, so that the boom system can operate at a higher height, increase the range of firefighting operations, and make firefighting equipment more convenient and flexible during firefighting operations.

[0015] Meanwhile, the second vehicle body is equipped with a first storage unit instead of a boom structure, so that most of the weight can be distributed to the first storage unit. That is, under the premise of the same vehicle chassis, the liquid carrying capacity of the first storage unit can be greater without exceeding the weight limit.

[0016] In other words, while ensuring that the second vehicle body meets the overall vehicle weight requirements, the liquid carrying capacity of the first storage unit on the second vehicle body is increased as much as possible. This allows for the provision of more extinguishing media during firefighting operations, enabling uninterrupted delivery of the extinguishing media to the end of the boom system for firefighting operations, increasing the duration of firefighting operations, and achieving rapid and effective firefighting.

[0017] By separating the boom system and the first storage unit onto different vehicle bodies, compared to related technologies that divide the liquid tank into three compartments to adjust different liquid levels, this method can ensure that each vehicle body meets the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. This achieves the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves firefighting efficiency, and maximizes the fire extinguishing range and the longest combat duration.

[0018] Optionally, there can be multiple second car bodies, that is, multiple second car bodies having the first storage component, thereby further increasing the liquid carrying capacity.

[0019] Optionally, the extinguishing medium may include, but is not limited to, liquid extinguishing media such as water and foam liquid.

[0020] Optionally, the extinguishing medium includes solid extinguishing media such as powder.

[0021] Optionally, the first vehicle body can specifically be a fire truck of the large-span high-pressure water jet type.

[0022] In addition, the fire-fighting equipment provided by the above-described technical solution of the present invention also has the following additional technical features:

[0023] In some technical solutions, optionally, the first vehicle body is also provided with a first connector, which is connected to the injection assembly; the first storage component is provided with a second connector, which can be connected to the first connector.

[0024] In this technical solution, the first vehicle body is further provided with a first connector, and the first material storage component is provided with a second connector. Specifically, the first connector is connected to the injection assembly.

[0025] The second connector can be connected to the first connector, thereby enabling the liquid flow path between the spray assembly and the first storage container, and thus providing the spray assembly with the extinguishing medium.

[0026] By connecting the first and second joints, the first and second vehicle bodies are combined into a large equipment during firefighting operations. This allows each vehicle body to meet the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. It satisfies the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves firefighting efficiency, and achieves the maximum firefighting range and the longest operation time.

[0027] In some technical solutions, the fire-fighting equipment may optionally include an adjustment component, which is located at the first connector or the second connector; wherein, when the adjustment component is located at the first connector, the adjustment component can drive the first connector to move relative to the second connector so that the first connector and the second connector can be connected; when the adjustment component is located at the second connector, the adjustment component can drive the second connector to move relative to the first connector so that the second connector and the first connector can be connected.

[0028] In this technical solution, the fire-fighting equipment is further defined as including an adjustment component, specifically, the adjustment component is installed on the first connector or the second connector.

[0029] Specifically, when the adjustment component is set in the first connector, the adjustment component can drive the first connector to move relative to the second connector so that the first connector and the second connector are facing each other, thereby realizing the automatic docking of the first connector and the second connector, that is, the mating connection.

[0030] When the adjustment component is set on the second connector, the adjustment component can drive the second connector to move relative to the first connector so that the second connector is opposite to the first connector, thereby realizing the automatic docking of the second connector and the first connector, that is, the mating connection.

[0031] In other words, by setting up adjustment components to move the first or second connector, automatic docking between the first and second connectors can be achieved. This means that by using remote water supply technology, the first and second vehicle bodies can be combined into a large device during firefighting operations. This allows each vehicle body to meet the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. This satisfies the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves firefighting efficiency, and achieves the maximum firefighting range and the longest operation time.

[0032] Optionally, provided that the cross-sectional shape of the first connector is a first circle and the cross-sectional shape of the second connector is a second circle, the first connector and the second connector are opposite to each other, that is, the center of the first circle and the center of the second circle are opposite to or coincide with each other.

[0033] In some technical solutions, the adjusting component can optionally also move the first or second connector and then reset it.

[0034] In this technical solution, the adjusting component can also reset the first connector after it has moved relative to the second connector. It is understood that when the adjusting component is installed on the first connector, it moves the first connector according to the position of the second connector to automatically connect the first and second connectors. After the fire extinguishing operation is completed, the first and second connectors are disconnected, and the adjusting component returns the first connector to its original position before movement, i.e., the initial position, to facilitate the next connection between the first and second connectors.

[0035] When the adjusting component is set on the second connector, the adjusting component moves the second connector according to the position of the first connector to automatically connect the second connector and the first connector. After the fire extinguishing operation is completed, the second connector and the first connector are disconnected, and the adjusting component returns the second connector to its position before movement, i.e., the initial position, so as to facilitate the next connection between the second connector and the first connector.

[0036] In some technical solutions, the fire-fighting equipment may optionally include a position detection element, which is located on the adjustment assembly; wherein, when the adjustment assembly is located on the first connector, the position detection element can detect the position information of the second connector, so that the adjustment assembly can drive the first connector to move according to the position information of the second connector; when the adjustment assembly is located on the second connector, the position detection element can detect the position information of the first connector, so that the adjustment assembly can drive the second connector to move according to the position information of the first connector.

[0037] In this technical solution, the fire-fighting equipment is further defined as including a position detection element. Specifically, the position detection element is installed in the adjustment assembly, and the position detection element can detect the position information of the second connector or the first connector.

[0038] Specifically, when the adjustment component is set on the first connector, the position detection component detects the position information of the second connector, and the adjustment component drives the first connector to move according to the position information of the second connector, so as to automatically connect the first connector and the second connector.

[0039] When the adjustment component is set on the second connector, the position detection component detects the position information of the first connector. Based on the position information of the first connector, the adjustment component drives the second connector to move so as to automatically connect the second connector and the first connector.

[0040] By setting up position detection components, the first and second connectors can be quickly and accurately connected, which helps to improve the efficiency of fire fighting operations.

[0041] Optionally, the position detection device includes a positioning sensor, specifically, a bidirectional positioning sensor.

[0042] In some technical solutions, the adjustment assembly optionally includes multiple adjustment elements, which are disposed on one of the first connector and the second connector, and the multiple adjustment elements can drive the first connector or the second connector to move in different directions.

[0043] In this technical solution, the adjustment assembly is defined as including multiple adjustment elements, specifically, the multiple adjustment elements are disposed on the first connector. Alternatively, the multiple adjustment elements are disposed on the second connector.

[0044] When multiple adjusting components are installed on the first connector, the multiple adjusting components can drive the first connector to move in different directions. In other words, by setting multiple adjusting components, the first connector can be moved in different directions, thereby further improving the accuracy of the adjusting component in adjusting the position of the first connector and further realizing the precise docking of the first connector and the second connector.

[0045] When multiple adjusting components are installed on the second connector, the multiple adjusting components can drive the second connector to move in different directions. In other words, by setting multiple adjusting components, the second connector can be moved in different directions, thereby further improving the accuracy of the adjusting component in adjusting the position of the second connector and further realizing the precise docking of the second connector and the first connector.

[0046] Optionally, taking the initial position of the first or second connector as the origin, the plurality of adjusting members include a first adjusting member, a second adjusting member, and a third adjusting member, wherein the first adjusting member can drive the first or second connector to move in the x-axis direction, the second adjusting member can drive the first or second connector to move in the y-axis direction, and the third adjusting member can drive the first or second connector to move in the z-axis direction.

[0047] In some technical solutions, each adjusting member optionally includes a driving part and a transmission part, wherein the transmission part is connected to the driving part, and one of the first connector and the second connector is connected to the transmission part.

[0048] In this technical solution, each adjusting component is defined as including a driving part and a transmission part. Specifically, the transmission part is connected to the driving part and the transmission part is connected to the first connector. Alternatively, the transmission part is connected to the second connector.

[0049] Specifically, when the transmission unit is connected to the first connector, the drive unit drives the first connector to move relative to the second connector through the transmission unit, so as to achieve automatic docking between the first connector and the second connector.

[0050] When the transmission unit is connected to the second connector, the drive unit drives the second connector to move relative to the first connector through the transmission unit, so as to realize the automatic docking of the second connector and the first connector.

[0051] Optionally, the transmission component may include a worm gear, lead screw, or chain.

[0052] Optionally, when the transmission part includes a worm, the worm includes a worm body and a worm half-shaft sleeve, the worm body is connected to the drive part and the worm half-shaft sleeve, and the worm half-shaft sleeve is connected to a first joint or a second joint.

[0053] Specifically, under the drive of the drive unit, the worm body rotates relative to the worm half-shaft sleeve, so that the worm half-shaft sleeve drives the first joint or the second joint to move.

[0054] In some technical solutions, the fire-fighting equipment may optionally include a connecting pipe, through which the first connector is connected to the second connector.

[0055] In this technical solution, the fire-fighting equipment is further defined as including a connecting pipeline. Specifically, the first connector and the second connector are connected through the connecting pipeline to realize the conduction of the liquid flow path between the spraying assembly and the first storage container, thereby providing the extinguishing medium to the spraying assembly.

[0056] Moreover, the first and second connectors are connected by a connecting pipeline, which means that the first and second vehicle bodies are combined into a large equipment during firefighting operations. This allows each vehicle body to meet the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. It satisfies the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves firefighting efficiency, and achieves the maximum firefighting range and the longest operation time.

[0057] In some technical solutions, the first vehicle body may optionally include a chassis and a liquid-carrying platform, wherein the boom system is located on the chassis, the liquid-carrying platform is located on the chassis, and the liquid-carrying platform is used to house counterweights that can be separated from the chassis.

[0058] In this technical solution, the first vehicle body is defined to also include a chassis and a liquid-carrying platform. Specifically, the boom system is mounted on the chassis.

[0059] The liquid-carrying platform is mounted on the chassis. Specifically, the liquid-carrying platform is used to house counterweights that can be separated from the chassis.

[0060] Understandably, the overall stability of a vehicle body refers to whether the entire vehicle is at risk of tipping over after the multiple movable booms of the boom system have been deployed. Higher stability means the vehicle is less likely to tip over. Overall stability = weight of boom / weight of the entire vehicle; the smaller this ratio, the better the stability.

[0061] Specifically, the first vehicle body is equipped with a boom system but not with a liquid storage device, so that most of the weight can be distributed to the boom system, that is, to increase the weight of the boom system as much as possible, so as to increase the working height of the boom system.

[0062] However, when multiple movable booms of the boom system are in the deployed state, the large weight of the booms can cause the entire vehicle to become unstable, resulting in poor overall stability and insufficient safety during operation.

[0063] By setting up a liquid-carrying platform to accommodate counterweights, and since the counterweights are not part of the first vehicle body, it is possible to increase the weight of the boom system on the first vehicle body as much as possible while ensuring that the first vehicle body meets the overall weight requirements. This allows the boom system to operate at a higher height, increasing the firefighting range, while also changing the center of gravity of the first vehicle body. This prevents the first vehicle body from tipping over during firefighting operations, significantly improving the stability of the first vehicle body and thus enhancing the safety and reliability of the firefighting equipment during firefighting operations.

[0064] In some technical solutions, the second vehicle body can optionally be formed as a counterweight.

[0065] In this technical solution, the second vehicle body acts as a counterweight, meaning it can travel onto the liquid-carrying platform of the first vehicle body. Since the second vehicle body is not a component of the first vehicle body, it allows for the weight of the boom system on the first vehicle body to be increased as much as possible while ensuring the first vehicle body meets the overall vehicle weight requirements. This results in a higher working height for the boom system, expanding the firefighting operation range, while simultaneously altering the center of gravity of the first vehicle body. This prevents the first vehicle body from tipping over during firefighting operations, significantly improving its stability and consequently enhancing the safety and reliability of the firefighting equipment during firefighting operations.

[0066] In addition, it is understandable that driving the second vehicle onto the liquid-carrying platform of the first vehicle can also help reduce the overall footprint of the fire-fighting equipment and meet the needs of various fire-fighting scenarios.

[0067] Optionally, after the second vehicle body travels to the liquid-carrying platform, the position of the first or second connector is adjusted by adjusting the components to achieve automatic docking between the first and second connectors.

[0068] In some technical solutions, the first vehicle body may optionally include a guide plate, which is located on the chassis and connected to the liquid-carrying platform on the side facing the boom system; wherein, when the second vehicle body is formed as a counterweight, the guide plate is used to guide the second vehicle body.

[0069] In this technical solution, the first vehicle body is further defined as including a guide plate. Specifically, the guide plate is set on the chassis, and the side of the guide plate facing the boom system is connected to the liquid-carrying platform. That is to say, the upper surface of the guide plate is a guiding surface, and the guiding surface is connected to the liquid-carrying platform. Thus, the second vehicle body is guided as it travels to the liquid-carrying platform, thereby improving the overall stability of the first vehicle body, reducing the difficulty of fire-fighting equipment operation, and improving operation efficiency.

[0070] In some technical solutions, optionally, the guide plate is movably connected to the chassis, and the guide plate is movable relative to the chassis between a first position and a second position; wherein, when the guide plate is in the first position, the side of the guide plate facing the boom system is tilted relative to at least a portion of the liquid-carrying platform to guide the second vehicle body; when the guide plate is in the second position, the side of the guide plate facing the boom system is flush with at least a portion of the liquid-carrying platform.

[0071] In this technical solution, the guide plate is movably connected to the chassis, meaning that the guide plate can move relative to the chassis.

[0072] Specifically, when firefighting operations are carried out, the guide plate moves to the first position, causing the guide plate to tilt relative to the liquid-carrying platform. This guides the second vehicle body as it travels to the liquid-carrying platform, improving the overall stability of the first vehicle body while reducing the operational difficulty of the firefighting equipment and increasing operational efficiency.

[0073] When the firefighting operation is completed, the second vehicle body leaves the liquid-carrying platform, and the guide plate moves to the second position, so that the guide surface of the guide plate is flush with the liquid-carrying plane. In other words, the free end of the guide plate is moved away from the ground, thereby preventing the guide plate from interfering with other structures during the movement of the first vehicle body.

[0074] In some technical solutions, the liquid-carrying platform may optionally include a limiting boss that protrudes toward one side of the boom system; wherein, when the second vehicle body is formed as a counterweight, the limiting boss is used to limit the second vehicle body.

[0075] In this technical solution, the liquid-carrying platform is defined to include a limiting boss. Specifically, the limiting boss protrudes towards the side of the boom system, that is, the limiting boss protrudes upward, so that when the second vehicle body travels onto the liquid-carrying platform, it can limit the second vehicle body, improve the stability of the second vehicle body on the liquid-carrying platform, and thus improve the safety and reliability of the fire-fighting equipment during fire-fighting operations.

[0076] In some technical solutions, the fire-fighting equipment may optionally include a second storage component, which can be connected to the spray assembly and serves as a counterweight.

[0077] In this technical solution, the fire-fighting equipment is also limited to a second storage unit, that is, other liquid storage devices can be accommodated on the liquid-carrying platform.

[0078] Since the second storage unit is not a component of the first vehicle body, it is possible to increase the weight of the boom system on the first vehicle body as much as possible while ensuring that the first vehicle body meets the overall weight requirements. This allows the boom system to operate at a higher height and increase the firefighting operation range. At the same time, it changes the center of gravity of the first vehicle body, thereby preventing the first vehicle body from tipping over during firefighting operations. This significantly improves the stability of the first vehicle body and, consequently, enhances the safety and reliability of the firefighting equipment during firefighting operations.

[0079] Optionally, the second storage container may contain fire extinguishing media.

[0080] Optionally, the second storage unit is equipped with a fourth connector, which can be connected to the first connector. This can prevent the first vehicle from overturning during firefighting operations, while increasing the overall liquid capacity of the firefighting equipment, extending the combat duration, and achieving effective fire extinguishing.

[0081] In some technical solutions, the first storage component may optionally be provided with a third connector for connecting to an external fire extinguishing medium.

[0082] In this technical solution, the first storage component is further provided with a third connector, specifically, the third connector is used to connect to the external fire extinguishing medium.

[0083] By installing a third connector, extinguishing media can be injected into the first storage container, thereby further extending the operational time of the fire-fighting equipment and enabling rapid and effective fire extinguishing operations. At the same time, it helps to further reduce the number of other water tanker fire trucks and improve fire extinguishing efficiency.

[0084] Optionally, the number of third connectors may be multiple.

Detailed Implementation

[0096] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0097] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0098] The following reference Figures 1 to 7 To describe the fire-fighting equipment 200 provided according to some embodiments of the present invention.

[0099] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a fire-fighting device 200 is proposed, which includes: at least two vehicle bodies 100, the at least two vehicle bodies 100 including a first vehicle body 110 and a second vehicle body 120, the first vehicle body 110 is provided with a boom system 111, the second vehicle body 120 is provided with a first storage unit 121, the first storage unit 121 is used to contain fire extinguishing medium; and a spraying assembly 130 is provided on the boom system 111 and can communicate with the first storage unit 121.

[0100] The fire-fighting equipment 200 provided in this embodiment of the invention includes at least two vehicle bodies 100 and a spraying assembly 130. Specifically, the at least two vehicle bodies 100 include a first vehicle body 110 and a second vehicle body 120. The first vehicle body 110 is provided with a boom system 111. It is understood that the boom system 111 includes multiple movable booms. Any one of the multiple movable booms can move relative to the remaining movable booms to extend or retract at least one movable boom.

[0101] Optionally, the multiple booms may include multiple folding arms, meaning that any folding arm can be folded relative to the others. Alternatively, the multiple booms may include multiple telescopic arms, meaning that any telescopic arm can extend or retract relative to the others. Or, the multiple booms may include at least one telescopic arm and at least one folding arm. The specific configuration can be tailored to actual needs.

[0102] The spray assembly 130 is mounted on the boom system 111. Optionally, the spray assembly 130 includes a connected spray pipe and a nozzle. The spray pipe is mounted on multiple movable booms, and can drive the spray pipe to move during the extension or retraction of the multiple movable booms. The spray pipe can communicate with the first storage container 121, and the nozzle is mounted on at least one movable boom. Specifically, during firefighting operations (water spraying operations), the extinguishing medium in the first storage container 121 is sprayed out through the nozzle after passing through the spray pipe.

[0103] Understandably, the large-span high-pressure firefighting equipment mainly includes the chassis 112 system, boom system 111, support system, water system, and electrical-hydraulic system. The main technical parameters include boom working height, total vehicle fluid capacity, and other parameters.

[0104] Because the overall vehicle weight and axle weight must comply with regulations, meaning they cannot exceed the permissible weight of chassis 112. It can be understood that the permissible weight of chassis 112 equals the boom weight plus the liquid load plus the weight of other components. This results in high-pressure water jet fire trucks in related technologies being unable to achieve optimal performance in both boom working height and liquid load.

[0105] The second vehicle body 120 is provided with a first material storage component 121, and the injection component 130 can communicate with the first material storage component 121. That is to say, the boom system 111 and the first material storage component 121 are set on two different vehicle bodies 100. That is, the first vehicle body 110 is provided with the boom system 111 but not with the liquid storage device, so that most of the weight can be distributed to the boom system 111. That is, under the premise of the same vehicle body 100 chassis 112, the boom system 111 can be higher without exceeding the weight limit.

[0106] In other words, while ensuring that the first vehicle body 110 meets the overall vehicle weight requirements, the weight of the boom system 111 on the first vehicle body 110 is increased as much as possible, so that the boom system 111 can operate at a higher height, increase the range of firefighting operations, and make the firefighting equipment 200 more convenient and flexible in the firefighting operation.

[0107] Meanwhile, the second vehicle body 120 is equipped with a first storage component 121 instead of a boom structure, so that most of the weight can be distributed to the first storage component 121. That is, under the same vehicle body 100 chassis 112, the liquid carrying capacity of the first storage component 121 can be greater without exceeding the weight limit.

[0108] In other words, while ensuring that the second vehicle body 120 meets the overall vehicle weight requirements, the liquid capacity of the first storage unit 121 on the second vehicle body 120 is increased as much as possible, so that more extinguishing medium can be provided during firefighting operations, and the extinguishing medium can be continuously delivered to the end of the boom system 111 for firefighting operations, thereby increasing the duration of firefighting operations and achieving rapid and effective firefighting.

[0109] By separating the boom system 111 and the first storage unit 121 onto different vehicle bodies 100, compared to the related technology of dividing the liquid tank into three compartments to adjust different liquid levels, this method can ensure that each vehicle body 100 meets the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. This satisfies the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves fire fighting efficiency, and achieves the maximum fire extinguishing range and the longest combat time.

[0110] Optionally, there can be multiple second vehicle bodies 120, that is, there can be multiple second vehicle bodies 120 having the first storage component 121, thereby further increasing the liquid carrying capacity.

[0111] Optionally, the extinguishing medium may include, but is not limited to, liquid extinguishing media such as water and foam liquid.

[0112] Optionally, the extinguishing medium includes solid extinguishing media such as powder.

[0113] Optionally, the first vehicle body 110 can specifically be a fire truck of the large-span high-pressure water jet type.

[0114] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the first vehicle body 110 is also provided with a first connector 114, which is connected to the injection assembly 130; the first storage component 121 is provided with a second connector 122, which can be connected to the first connector 114.

[0115] In this embodiment, the first vehicle body 110 is further provided with a first connector 114, and the first storage component 121 is provided with a second connector 122. Specifically, the first connector 114 is connected to the spraying assembly 130.

[0116] The second connector 122 can be connected to the first connector 114, thereby enabling the liquid flow path between the spray assembly 130 and the first storage container 121, and thus providing the spray assembly 130 with extinguishing medium.

[0117] By connecting the first connector 114 and the second connector 122, the first vehicle body 110 and the second vehicle body 120 can be combined into a large equipment during firefighting operations. This allows each vehicle body 100 to meet the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. This satisfies the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves firefighting efficiency, and achieves the maximum firefighting range and the longest combat time.

[0118] like Figure 6 As shown, in some embodiments, the fire-fighting equipment 200 may optionally include an adjustment component 140, which is disposed on the first connector 114 or the second connector 122. When the adjustment component 140 is disposed on the first connector 114, the adjustment component 140 can drive the first connector 114 to move relative to the second connector 122 so that the first connector 114 and the second connector 122 are connected. When the adjustment component 140 is disposed on the second connector 122, the adjustment component 140 can drive the second connector 122 to move relative to the first connector 114 so that the second connector 122 and the first connector 114 are connected.

[0119] In this embodiment, the fire-fighting equipment 200 is further defined as including an adjustment component 140, specifically, the adjustment component 140 is disposed on the first connector 114 or the second connector 122.

[0120] Specifically, when the adjustment component 140 is set in the first connector 114, the adjustment component 140 can drive the first connector 114 to move relative to the second connector 122 so that the first connector 114 and the second connector 122 are opposite each other, thereby realizing the automatic docking of the first connector 114 and the second connector 122, that is, the mating connection.

[0121] When the adjustment component 140 is set on the second connector 122, the adjustment component 140 can drive the second connector 122 to move relative to the first connector 114 so that the second connector 122 is opposite to the first connector 114, thereby realizing the automatic docking of the second connector 122 and the first connector 114, that is, the mating connection.

[0122] In other words, by setting the adjustment component 140 to drive the first connector 114 or the second connector 122 to move, the automatic docking between the first connector 114 and the second connector 122 can be achieved. That is, by using remote water supply technology, the first vehicle body 110 and the second vehicle body 120 can be combined into a large device during the fire fighting operation. This allows each vehicle body 100 to meet the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. This satisfies the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves fire fighting efficiency, and achieves the maximum fire fighting range and the longest operation time.

[0123] Optionally, provided that the cross-sectional shape of the first connector 114 is a first circle and the cross-sectional shape of the second connector 122 is a second circle, the first connector 114 and the second connector 122 are opposite to each other, that is, the center of the first circle and the center of the second circle are opposite to or coincide with each other.

[0124] In some embodiments, the adjustment component 140 may optionally also be able to move the first connector 114 or the second connector 122 and then reset it.

[0125] In this embodiment, the adjusting component 140 can also reset the first connector 114 relative to the second connector 122 after movement. It is understood that when the adjusting component 140 is positioned on the first connector 114, it moves the first connector 114 according to the position of the second connector 122 to automatically connect the first connector 114 and the second connector 122. After the fire extinguishing operation is completed, the first connector 114 and the second connector 122 are disconnected, and the adjusting component 140 returns the first connector 114 to its original position before movement, i.e., the initial position, to facilitate the next connection between the first connector 114 and the second connector 122.

[0126] When the adjusting component 140 is set on the second connector 122, the adjusting component 140 moves the second connector 122 according to the position of the first connector 114 to automatically connect the second connector 122 and the first connector 114. After the fire extinguishing operation is completed, the second connector 122 and the first connector 114 are disconnected, and the adjusting component 140 returns the second connector 122 to its position before movement, i.e., the initial position, so as to facilitate the next connection between the second connector 122 and the first connector 114.

[0127] like Figure 6 As shown, in some embodiments, the fire-fighting equipment 200 may optionally include a position detection element 150, which is disposed on the adjustment assembly 140; wherein, when the adjustment assembly 140 is disposed on the first connector 114, the position detection element 150 can detect the position information of the second connector 122, so that the adjustment assembly 140 drives the first connector 114 to move according to the position information of the second connector 122; when the adjustment assembly 140 is disposed on the second connector 122, the position detection element 150 can detect the position information of the first connector 114, so that the adjustment assembly 140 drives the second connector 122 to move according to the position information of the first connector 114.

[0128] In this embodiment, the fire-fighting equipment 200 is further defined as including a position detection element 150. Specifically, the position detection element 150 is disposed in the adjustment assembly 140, and the position detection element 150 is capable of detecting the position information of the second connector 122 or the first connector 114.

[0129] Specifically, when the adjustment component 140 is set on the first connector 114, the position detection component 150 detects the position information of the second connector 122. The adjustment component 140 drives the first connector 114 to move according to the position information of the second connector 122, so as to automatically connect the first connector 114 and the second connector 122.

[0130] When the adjustment component 140 is set on the second connector 122, the position detection component 150 detects the position information of the first connector 114. The adjustment component 140 moves the second connector 122 according to the position information of the first connector 114, so as to automatically connect the second connector 122 and the first connector 114.

[0131] By setting the position detection component 150, the first connector 114 and the second connector 122 can be quickly and accurately connected, which is conducive to improving the efficiency of fire fighting operations.

[0132] Optionally, the position detection element 150 includes a positioning sensor, specifically a bidirectional positioning sensor.

[0133] like Figure 6As shown, in some embodiments, optionally, the adjustment assembly 140 includes a plurality of adjustment members 141, which are disposed on one of the first connector 114 and the second connector 122, and the plurality of adjustment members 141 can drive the first connector 114 or the second connector 122 to move in different directions.

[0134] In this embodiment, the adjustment assembly 140 is defined to include a plurality of adjustment members 141. Specifically, the plurality of adjustment members 141 are disposed on the first connector 114. Alternatively, the plurality of adjustment members 141 are disposed on the second connector 122.

[0135] When multiple adjusting members 141 are provided on the first connector 114, the multiple adjusting members 141 can drive the first connector 114 to move in different directions. In other words, by providing multiple adjusting members 141, the first connector 114 can be moved in different directions, thereby further improving the accuracy of the adjusting assembly 140 in adjusting the position of the first connector 114 and further realizing the precise docking of the first connector 114 and the second connector 122.

[0136] When multiple adjusting members 141 are provided on the second connector 122, the multiple adjusting members 141 can drive the second connector 122 to move in different directions. In other words, by providing multiple adjusting members 141, the second connector 122 can be moved in different directions, thereby further improving the accuracy of the adjusting assembly 140 in adjusting the position of the second connector 122, and further realizing the precise docking of the second connector 122 and the first connector 114.

[0137] Optionally, with the initial position of the first connector 114 or the second connector 122 as the origin, the plurality of adjusting members 141 include a first adjusting member, a second adjusting member, and a third adjusting member. The first adjusting member can drive the first connector 114 or the second connector 122 to move in the x-axis direction, the second adjusting member can drive the first connector 114 or the second connector 122 to move in the y-axis direction, and the third adjusting member can drive the first connector 114 or the second connector 122 to move in the z-axis direction.

[0138] like Figure 6 As shown, in some embodiments, each adjusting member 141 may optionally include a driving part 1411 and a transmission part 1412, wherein the transmission part 1412 is connected to the driving part 1411, and one of the first connector 114 and the second connector 122 is connected to the transmission part 1412.

[0139] In this embodiment, each adjusting member 141 is defined to include a driving part 1411 and a transmission part 1412. Specifically, the transmission part 1412 is connected to the driving part 1411 and is connected to the first connector 114. Alternatively, the transmission part 1412 is connected to the second connector 122.

[0140] Specifically, when the transmission unit 1412 is connected to the first connector 114, the drive unit 1411 drives the first connector 114 to move relative to the second connector 122 through the transmission unit 1412, so as to realize the automatic docking of the first connector 114 and the second connector 122.

[0141] When the transmission unit 1412 is connected to the second connector 122, the drive unit 1411 drives the second connector 122 to move relative to the first connector 114 through the transmission unit 1412, so as to realize the automatic docking of the second connector 122 and the first connector 114.

[0142] Optionally, the transmission unit 1412 may include a worm, lead screw, or chain, etc.

[0143] Optionally, when the transmission unit 1412 includes a worm, the worm includes a worm body and a worm half-shaft sleeve. The worm body is connected to the drive unit 1411 and the worm half-shaft sleeve, and the worm half-shaft sleeve is connected to the first connector 114 or the second connector 122.

[0144] Specifically, under the drive of the drive unit 1411, the worm body rotates relative to the worm half-shaft sleeve, so that the worm half-shaft sleeve drives the first joint 114 or the second joint 122 to move.

[0145] like Figure 7 As shown, in a specific embodiment, the steps for the automatic docking of the first connector 114 and the second connector 122 are as follows:

[0146] Step 102: Position the water inlet of the high-pressure jet truck as the origin.

[0147] Among them, the water circuit interface of the high-pressure jet truck is the first connector 114.

[0148] Step 104: Obtain the location information of the waterway interface of the tanker truck through a bidirectional positioning sensor;

[0149] Among them, the bidirectional positioning sensor is the position detection component 150.

[0150] Step 106: Based on the location information of the water circuit interface of the large tanker truck, compare it with the location of the water circuit interface of the high-pressure jet truck (origin) to determine whether the two location information overlap.

[0151] Among them, the waterway interface of the large tanker truck is the second connector 122.

[0152] Step 108: If they do not overlap, align the water inlets of the high-pressure jet truck using the alignment mechanism.

[0153] Among them, the centering mechanism is the adjustment component 140.

[0154] Step 110: After centering is completed, water injection is performed. After the operation is completed, the interface needs to be released, and the water interface of the high-pressure water jet truck will return to its original position, waiting for the next docking.

[0155] Among them, releasing the interface means that the first connector 114 is reset after moving.

[0156] In some embodiments, the fire-fighting equipment 200 may optionally include a connecting pipe, through which the first connector 114 is connected to the second connector 122.

[0157] In this embodiment, the fire-fighting equipment 200 is further defined as including a connecting pipe. Specifically, the first connector 114 and the second connector 122 are connected through the connecting pipe, thereby realizing the conduction of the liquid flow path between the spray assembly 130 and the first storage container 121, and thus providing the fire extinguishing medium to the spray assembly 130.

[0158] Moreover, the first connector 114 and the second connector 122 are connected by a connecting pipeline, which means that during the firefighting operation, the first vehicle body 110 and the second vehicle body 120 are combined into a large equipment. This allows each vehicle body 100 to meet the overall vehicle weight requirements while optimizing the two technical parameters of boom working height and liquid load. This satisfies the dual advantages of high boom and high liquid load, reduces the number of other water tanker fire trucks, improves firefighting efficiency, and achieves the maximum firefighting range and the longest operation time.

[0159] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the first vehicle body 110 may optionally include a chassis 112 and a liquid-carrying platform 113, wherein the boom system 111 is disposed on the chassis 112, the liquid-carrying platform 113 is disposed on the chassis 112, and the liquid-carrying platform 113 is used to accommodate a counterweight 160 that can be separated from the chassis 112.

[0160] In this embodiment, the first vehicle body 110 is further defined as including a chassis 112 and a liquid-carrying platform 113. Specifically, the boom system 111 is mounted on the chassis 112.

[0161] The liquid-carrying platform 113 is mounted on the chassis 112. Specifically, the liquid-carrying platform 113 is used to house the counterweight 160, which is separable from the chassis 112.

[0162] Understandably, the overall stability of the vehicle body 100 refers to whether the entire vehicle is at risk of tipping over after the multiple movable booms of the boom system 111 are deployed. Higher stability means the vehicle is less likely to tip over. Overall stability = weight of boom / weight of the whole; the smaller this ratio, the better the stability.

[0163] Specifically, the first vehicle body 110 is equipped with a boom system 111 but not with a liquid storage device, so that most of the weight can be distributed to the boom system 111, that is, the weight of the boom system 111 can be increased as much as possible to increase the working height of the boom system 111.

[0164] However, when the multiple movable booms of the boom system 111 are in the extended state, the large weight of the booms can cause the entire vehicle to become unstable, meaning that the overall stability of the vehicle is poor and safety is insufficient during operation.

[0165] By setting up a liquid-carrying platform 113 to accommodate a counterweight 160, since the counterweight 160 is not a component of the first vehicle body 110, the weight of the boom system 111 on the first vehicle body 110 can be increased as much as possible while ensuring that the first vehicle body 110 meets the overall vehicle weight requirements. This allows the boom system 111 to operate at a higher height, increasing the firefighting operation range. At the same time, it changes the center of gravity of the first vehicle body 110, thereby preventing the first vehicle body 110 from tipping over during firefighting operations. This significantly improves the stability of the first vehicle body 110, thereby enhancing the safety and reliability of the firefighting equipment 200 during firefighting operations.

[0166] Optionally, the first vehicle body 110 also includes a support platform 115 and a support leg assembly 116. The support platform 115 is mounted on the chassis 112, and the boom system 111 is movably connected to the support platform 115.

[0167] The outrigger assembly 116 is mounted on the chassis 112 and is movable relative to the chassis 112 to switch between an extended state and a retracted state.

[0168] like Figure 1 As shown, in some embodiments, the second vehicle body 120 is optionally formed as a counterweight 160.

[0169] In this embodiment, the second vehicle body 120 is configured as a counterweight 160, meaning that the second vehicle body 120 can travel onto the liquid-carrying platform 113 of the first vehicle body 110. Since the second vehicle body 120 is not a component of the first vehicle body 110, it is possible to increase the weight of the boom system 111 on the first vehicle body 110 as much as possible while ensuring that the first vehicle body 110 meets the overall vehicle weight requirements. This allows the boom system 111 to operate at a higher height, increasing the firefighting operation range. At the same time, it changes the center of gravity of the first vehicle body 110, thereby preventing the first vehicle body 110 from tipping over during firefighting operations. This significantly improves the stability of the first vehicle body 110, thereby enhancing the safety and reliability of the firefighting equipment 200 during firefighting operations.

[0170] In addition, it is understandable that driving the second vehicle body 120 onto the liquid-carrying platform 113 of the first vehicle body 110 can also help reduce the overall footprint of the fire-fighting equipment 200, which can meet the needs of various fire-fighting scenarios.

[0171] Optionally, after the second vehicle body 120 travels onto the liquid-carrying platform 113, the position of the first connector 114 or the second connector 122 can be adjusted by the adjustment component 140 to achieve automatic docking between the first connector 114 and the second connector 122.

[0172] In one specific embodiment, in non-water-spraying operations (firefighting operations), the first vehicle body 110 and the second vehicle body 120 are two independent vehicles. The vehicle containing the boom (boom system 111) is called the boom vehicle unit (first vehicle body 110), and the vehicle containing the liquid tank (first storage unit 121) is called the liquid tank vehicle unit (second vehicle body 120). Both vehicles operate independently during operation.

[0173] In water-fighting (firefighting) operations, two vehicles need to be used together. The specific steps are as follows:

[0174] After the boom vehicle unit (first vehicle body 110) arrives at its destination, it needs to first deploy the outriggers (outrigger assembly 116) to support the boom vehicle unit (first vehicle body 110).

[0175] After the boom vehicle unit (first vehicle body 110) is raised, the first boom (first movable boom 1111) is extended to 90° to reserve space for the liquid-carrying platform 113.

[0176] After the boom (multiple movable booms) is deployed, the liquid tank vehicle unit (second vehicle body 120) is driven onto the liquid-carrying platform 113;

[0177] After the liquid-carrying vehicle unit (second vehicle body 120) is in place, the water interface (first connector 114 and second connector 122) is automatically docked.

[0178] After the water interface is automatically connected, the system will display that the connection is successful, and then other booms (second movable boom 1112) will be deployed to reach the designated posture for firefighting operations.

[0179] like Figure 3 and Figure 4 As shown, in some embodiments, the first vehicle body 110 may optionally include a guide plate 117, which is disposed on the chassis 112 and is connected to the liquid-carrying platform 113 on one side facing the boom system 111; wherein, when the second vehicle body 120 is formed as a counterweight 160, the guide plate 117 is used to guide the second vehicle body 120.

[0180] In this embodiment, the first vehicle body 110 is further defined as including a guide plate 117. Specifically, the guide plate 117 is disposed on the chassis 112, and the side of the guide plate 117 facing the boom system 111 is connected to the liquid-carrying platform 113. That is to say, the upper surface of the guide plate 117 is a guiding surface, and the guiding surface is connected to the liquid-carrying platform 113. Thus, the second vehicle body 120 is guided during the process of the second vehicle body 120 traveling to the liquid-carrying platform 113. This can improve the overall stability of the first vehicle body 110, while also reducing the operational difficulty of the fire-fighting equipment 200 and improving operational efficiency.

[0181] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the guide plate 117 is movably connected to the chassis 112, and the guide plate 117 is movable relative to the chassis 112 between a first position and a second position; wherein, when the guide plate 117 is in the first position, one side of the guide plate 117 facing the boom system 111 is inclined relative to at least a portion of the liquid-carrying platform 113 for guiding the second vehicle body 120; when the guide plate 117 is in the second position, one side of the guide plate 117 facing the boom system 111 is flush with at least a portion of the liquid-carrying platform 113.

[0182] In this embodiment, the guide plate 117 is movably connected to the chassis 112, that is, the guide plate 117 can move relative to the chassis 112.

[0183] Specifically, when firefighting operations are carried out, the guide plate 117 moves to the first position, causing the guide plate 117 to tilt relative to the liquid-carrying platform 113. This guides the second vehicle body 120 as it travels to the liquid-carrying platform 113, improving the overall stability of the first vehicle body 110 while reducing the operational difficulty of the firefighting equipment 200 and increasing operational efficiency.

[0184] When the firefighting operation is completed, the second vehicle body 120 leaves the liquid-carrying platform 113, and the guide plate 117 moves to the second position, so that the guide surface of the guide plate 117 is flush with the liquid-carrying plane. That is, the free end of the guide plate 117 is moved away from the ground, thereby preventing the guide plate 117 from interfering with other structures during the movement of the first vehicle body 110.

[0185] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, the liquid-carrying platform 113 includes a limiting boss 170, which protrudes toward one side of the boom system 111; wherein, when the second vehicle body 120 is formed as a counterweight 160, the limiting boss 170 is used to limit the second vehicle body 120.

[0186] In this embodiment, the liquid-carrying platform 113 is defined to include a limiting boss 170. Specifically, the limiting boss 170 protrudes towards the side of the boom system 111, that is, the limiting boss 170 protrudes upward, so that when the second vehicle body 120 travels onto the liquid-carrying platform 113, the second vehicle body 120 can be limited, thereby improving the stability of the second vehicle body 120 on the liquid-carrying platform 113, and thus improving the safety and reliability of the fire-fighting equipment 200 during fire-fighting operations.

[0187] like Figure 4 As shown, in some embodiments, the fire-fighting equipment 200 may optionally include a second storage component 161, which is connected to the spray assembly 130 and is configured as a counterweight 160.

[0188] In this embodiment, the fire-fighting equipment 200 is further defined as including a second storage component 161, that is, other liquid storage devices can be accommodated on the liquid-carrying platform 113.

[0189] Since the second storage component 161 is not a part of the first vehicle body 110, it is possible to increase the weight of the boom system 111 on the first vehicle body 110 as much as possible while ensuring that the first vehicle body 110 meets the overall vehicle weight requirements. This allows the boom system 111 to operate at a higher height and increase the fire-fighting operation range. At the same time, it changes the center of gravity of the first vehicle body 110, thereby preventing the first vehicle body 110 from overturning during fire-fighting operations. This significantly improves the stability of the first vehicle body 110 and thus enhances the safety and reliability of the fire-fighting equipment 200 during fire-fighting operations.

[0190] Optionally, the second storage container 161 contains a fire extinguishing medium.

[0191] Optionally, the second storage unit 161 is provided with a fourth connector, which can be connected to the first connector 114. This can prevent the first vehicle body 110 from overturning during firefighting operations, while increasing the overall liquid capacity of the firefighting equipment 200, extending the combat duration, and achieving effective fire extinguishing.

[0192] like Figure 5 As shown, in some embodiments, the first storage component 121 may optionally be provided with a third connector 123, which is used to connect to an external fire extinguishing medium.

[0193] In this embodiment, the first storage component 121 is further provided with a third connector 123, specifically, the third connector 123 is used to connect to an external fire extinguishing medium.

[0194] By setting the third connector 123, fire extinguishing medium can be injected into the first storage container 121, thereby further increasing the operating time of the fire-fighting equipment 200 and enabling rapid and effective fire extinguishing operations. At the same time, it is beneficial to further reduce the number of other water tanker fire trucks and improve fire extinguishing efficiency.

[0195] Optionally, the number of third connectors 123 may be multiple.
