[0001] The present invention relates to the field of fire fighting technology, and in particular to a fire fighting truck based on a drone. Background Art

[0002] As a new industrial technology, drone firefighting has been widely used in various fields. In China, many firefighting agencies have successfully used drones to conduct fire scene reconnaissance and monitoring, and drop rescue supplies, with very obvious results.

[0003] The overall solution of accurate, intuitive and comprehensive fire scene analysis data can provide timely information for on-site rescue. On this basis, there are very few multifunctional firefighting drones that can perform tasks near the fire scene, especially those that can still perform tasks near the fire scene. Due to technical, engineering and funding issues, few people dare to touch them. Experts believe that with the popularization of science and technology, drones have gradually entered everyone's field of vision, among which industrial-grade drones have gradually been applied to various fields and played their own roles, especially in high-risk fields dominated by firefighting. The use of drones to replace some human actions is self-evident for the firefighting industry. Therefore, drones have broad application prospects in the field of firefighting. The advantages and characteristics of drones can be reflected and played in firefighting. Combined with the actual combat needs of the firefighting force, drones can play many roles in the firefighting force.

[0004] Based on this, there is an urgent need for a drone-based fire truck with a reasonable layout and novel design. Summary of the invention

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Example 1

[0028] See also Figure 1-6 A fire truck based on a drone comprises a fire truck body 1, on which a crew cabin 10 and a body 11 are sequentially carried, wherein the body 11 is a double-layer structure, and the upper and lower layers are connected by a base frame 110; the upper layer comprises a top cover hatch 111 hinged on the left and right sides of the base frame 110, and a lifting platform 112 is installed on the base frame 110; the lower layer comprises a lower side lift door 113 hinged on the left and right sides of the base frame 110, and a sliding platform 114 is arranged under the lower side lift door 113, and the lifting platform 112 and the sliding platform 114 are both used to place a drone 2, and a control console is installed in the crew cabin 10 for commanding and controlling the drone 2.

[0029] The fire truck of the present embodiment is designed as a double-layer structure, and the design is reasonable; both the upper and lower layers can accommodate drones. When the top cover doors on both sides of the upper layer are closed, a relatively closed compartment can be formed. When the top cover doors on both sides are opened, the drones on the lifting platform on the upper layer can be commanded and controlled through the control console in the crew cabin, and the drones on the lifting platform can be dispatched to perform related tasks for large drones; in addition, when the lower side doors on both sides of the lower layer are opened and the sliding platform is extended to the outside by sliding, the drones on the sliding platform can be dispatched, which can be small drones; the fire truck of the present embodiment is reasonably designed, and the space is maximized. The fire truck can be combined with drones to perform rapid operations.

[0030] In a specific example, the base frame 110 is in an "inverted T-shape", with a storage compartment 1100 in the middle for storing firefighting tools and equipment, an ammunition compartment 115 in the lower layer, and a rear lift door 117 at the rear end of the body 11 .

[0031] The frame design of this embodiment is novel and makes rational use of the compartment space of the fire truck. In addition, without affecting the basic functions of the fire truck, it is convenient for the UAV to land and take off. The fire truck of this embodiment is similar to a "land aircraft carrier" and provides a good take-off environment and space for the UAV.

[0032] In a specific example, the crew cabin 10 is provided with a roof ladder 100 and a roof remote control station 101 , and the roof remote control station 101 is used to transmit and receive signals from the drone 2 .

[0033] After the fire truck of this embodiment arrives at the designated location, the firefighters start to command and control the UAV at the control console in the cabin, or the firefighters can also climb up to the roof ladder from the cabin and remotely control the UAV through the roof remote control console.

[0034] In a specific example, the lifting platform 112 includes a landing gear 1120, a lifting bracket 1121, an electric push rod 1122, a fixed bracket 1123 and a push rod fixed bracket 1124 installed in sequence from top to bottom, the lifting bracket 1121 includes a first flip bracket 11210 and a second flip bracket 11211 which are rotatably connected to each other from the middle part, the first flip bracket 11210 and the second flip bracket 11211 are respectively hinged and slidably connected to the landing gear 1120 and the fixed bracket 1123, the bottom of the fixed bracket 1123 is connected to the push rod fixed bracket 1124, the telescopic end of the electric push rod 1122 is connected to the middle part of the second flip bracket 11211, and the fixed end of the electric push rod 1122 is connected to the push rod fixed bracket 1124.

[0035] In this embodiment, the telescopic end of the electric push rod drives the first flip bracket and the second flip bracket to flip, thereby driving the landing gear and the fixed bracket to move away from and approach each other, so as to adjust the landing gear height, thereby enabling the automatic take-off preparation of the drone.

[0036] In a specific example, it also includes a landing gear self-locking mechanism 116. When the landing gear self-locking mechanism 116 is located at the bottom of the landing gear 1120, the landing gear self-locking mechanism 116 is installed on the top of the second flip bracket 11211. When the landing gear 1120 rises or falls, the top of the second flip bracket 11211 slides freely left and right at the bottom of the landing gear 1120, thereby driving the landing gear self-locking mechanism 116 to move horizontally to unlock and lock the drone 2.

[0037] During the process of rising and falling of the landing gear of this embodiment, the top of the second flip bracket automatically slides left and right at the bottom of the landing gear. Therefore, a synchronous landing gear self-locking mechanism can be installed on the top of the second flip bracket, so that when the landing gear rises into place, the landing gear self-locking mechanism changes from a locked state to an unlocked state; when the UAV completes its work and retracts to the landing gear, as the landing gear descends, the top of the second flip bracket drives the landing gear self-locking mechanism to slide to the left, slowly locking the UAV. This is convenient and fast, with a clever design and a high degree of automation.

[0038] It should be noted that the landing gear self-locking mechanism of this embodiment can be a locking rod. When moving horizontally left and right, the base support feet of the drone can be locked with limit holes that match the landing gear self-locking mechanism, thereby completing the self-locking and self-unlocking of the drone.

[0039] In a specific example, when the landing gear self-locking mechanism 116 is located at the top of the landing gear 1120, the landing gear self-locking mechanism 116 includes a pressure rod 1160, a rocker arm 1161, a fixed frame 1162 and a synchronous push rod 1163, and the fixed frame 1162 is hingedly connected to the pressure rod 1160 through two rocker arms 1161, wherein the middle part of a rocker arm 1161 is connected to the telescopic end of the synchronous push rod 1163, and the fixed end of the synchronous push rod 1163 is connected to the rear end of the fixed frame 1162, and the pressure rod is driven to move forward and backward by the telescopic drive of the synchronous push rod 1163 to lock and unlock the drone 2.

[0040] When the landing gear self-locking mechanism of this embodiment is located at the top of the landing gear, the UAV is unlocked and locked by extending and retracting the synchronous push rod, and works in conjunction with the lifting and lowering of the landing gear. When the landing gear rises to the set lifting position, the UAV is unlocked by controlling the pressure rod of the synchronous push rod to be retracted; when the landing gear descends to the set position, the UAV is locked by controlling the pressure rod of the synchronous push rod to be extended to prevent the UAV from shaking.

[0041] In a specific example, a slider 11212 is provided at the bottom of the first flip bracket 11210, and a rotational connection between the slider 11212 and the first flip bracket 11210 is used to improve the smoothness of flipping. The telescopic end of the electric push rod 1122 is hinged to the middle part of the second flip bracket 11211, the fixed end of the electric push rod 1122 is hinged to the push rod fixed bracket 1124, and the second flip bracket 11211 is slidably and rotationally connected to the bottom of the landing gear 1120 to improve the lifting smoothness of the lifting platform.

[0042] The various flipping points and sliding points of this embodiment are hinged and rotatably connected, which improves the lifting and lowering smoothness of the lifting platform, improves the suitability of the lifting platform of this embodiment, prevents the platform from getting stuck, and improves the fault tolerance rate.

[0043] In a specific example, the top cover hatch 111 includes a transparent outer cover 1110, a top cover frame 1111, a push rod pull ear 1112, a long row of hinges 1113, a proximity switch signal plate 1114 and a cylinder push rod 1115. The transparent outer cover 1110 is provided with a plurality of criss-cross top cover frames 1111 for improving strength. One side of the transparent outer cover 1110 is hinged to the upper part of the base frame 110 through a long row of hinges 1113. At least one of the left and right ends of the transparent outer cover 1110 is provided with a push rod pull ear 1112, a cylinder push rod 1115 and a proximity switch signal plate 1114. The transparent outer cover 1110 is flipped closed and opened by the extension and retraction of the cylinder push rod 1115. When closed or opened in place, the cylinder push rod 1115 is controlled to stop working by the proximity switch signal plate 1114.

[0044] In this embodiment, the push rod pull ear, the cylinder push rod and the proximity switch signal plate cooperate to realize the opening and closing of the transparent outer cover on the upper part of the fire truck, which is convenient and quick; and provides a good environment for the take-off of the drone.

[0045] In a specific example, the drone 2 is a jet fire-fighting and rescue drone or a tethered lighting drone or a high-performance reconnaissance and survey drone or a tethered communication base station drone. The jet fire-fighting and rescue drone is used to spray dry powder or foam water for fire extinguishing; the tethered lighting drone can be connected to the mains or generator, the tethered cable length is ≥50m, and the simulated solar light source does not interfere with the work of ground crew; the high-performance reconnaissance and survey drone has a maximum flight time of ≥50 minutes, a protection level of ≥IP45, multi-directional obstacle avoidance, and is equipped with a zoom visible light, high-resolution thermal imaging, and laser ranging three-light integrated camera; the tethered communication base station drone supports tethered power supply, an altitude of ≥200 meters, and is mounted on a public network communication base station.

[0046] The above four types of drones of the multifunctional fire-fighting and rescue drone of this embodiment support forward / downward spraying of dry powder or foam water agent for fire extinguishing, support connecting 25-40mm diameter fire hose to spray foam for fire extinguishing, support launching window-breaking bombs and fire-extinguishing bombs, support carrying at least 2 rescue material packages at the same time for throwing rescue, and are equipped with laser aiming devices and digital wireless broadband image transmission systems.

[0047] In addition, it should be noted that the UAV of this embodiment has the following advantages when working with a fire truck:

[0048] 1. Disaster inspection

[0049] When a disaster occurs, using drones for disaster reconnaissance can, firstly, ignore the terrain and environment and conduct reconnaissance flexibly and flexibly, especially at some urgent, difficult and dangerous disaster sites where the reconnaissance team is unable to conduct reconnaissance, drones can quickly conduct reconnaissance. Secondly, drone reconnaissance can effectively improve the efficiency of reconnaissance, identify the key factors of disaster accidents at the first time, so that commanders can make correct decisions. Third, it can effectively avoid casualties, prevent people from entering toxic, flammable and explosive dangerous environments, and fully and carefully grasp the situation on the scene. Fourth, integrated detection modules are used for detection. For example, combustible gas detectors and toxic gas detectors are integrated to remotely detect the concentration of related gases at flammable and explosive and chemical accident disaster sites, thereby obtaining key information on dangerous areas;

[0050] 2. Monitoring and tracking

[0051] The role of drones is not limited to disaster investigation. The various disaster accident scenes faced by fire brigades often change rapidly. In the process of handling disaster accidents, the use of drones for real-time monitoring and tracking can provide accurate disaster changes, making it easier for command centers at all levels to grasp the dynamic disaster situation in a timely manner, so as to make quick and accurate countermeasures and minimize losses.

[0052] 3. Auxiliary rescue

[0053] Using drones to integrate or flexibly carry key equipment can provide assistance for rescue in various situations. First, integrated voice and loudspeaker modules can convey instructions. Using drones to shout or convey instructions in the air can be more effective than shouting or instructions on the ground. It is especially suitable for rescue in high-altitude and high-rise projects. Using drones as carriers can effectively convey key instructions. Second, it opens up rescue paths for rescue. For example, in water and mountain rescue, the use environment and range of existing throwers are very limited, and the accuracy is poor. Using rescue drones to assist in throwing ropes or carry key equipment (such as respirators, rescue ropes, etc.) can create new ways for rescue and open up life-saving channels, and it is accurate and efficient. Third, integrated communication equipment, using drones as communication relays. For example, in environments where there is communication blockage such as earthquakes and mountains, drones are integrated with relay modules to act as temporary relay stations, so that wireless communication links can be established in extreme environments. Fourth, drones are used for emergency mapping. By utilizing the drone’s integrated aerial photography and mapping module, all conditions at the disaster site can be recorded and transmitted to the on-site command center, and emergency mapping of the disaster site’s terrain can be conducted, providing strong support for the implementation of rescue operations.

[0054] 4. Auxiliary Supervision

[0055] Aerial photography can be used to achieve comprehensive and real-time monitoring of high-rise and super-high-rise buildings, timely detection of fire hazards, real-time control of fire situations at fire scenes, building fire inspections or on-site fire image storage, and the aerial surveillance video can be connected to other security or fire monitoring systems. It supports large-capacity and long-term image storage and retrieval, and supports remote viewing and control of some functions through smart terminals.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
