DETAILED DESCRIPTION

[0028] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0029] like Figure 1-Figure 9 As shown, a mobile fire-fighting device includes two mutually parallel first main pipes 1 and second main pipes 2, a telescopic connecting pipe 3, two first sub-pipes 4, two second sub-pipes 5 and a barrier assembly 8, and the tops of the first main pipe 1, the second main pipe 2, the two first sub-pipes 4 and the two second sub-pipes 5 are all provided with a plurality of water spray holes 120. Among them, the first main pipe 1 and the second main pipe 2 mainly play the role of water flow and support installation. The connecting pipe 3, the two first sub-pipes 4 and the two second sub-pipes 5 mainly play the role of communication. The barrier assembly 8 mainly plays the role of barrier obstacles. It should be noted that the telescopic connecting pipe 3 can be composed of two pipes with different diameters, wherein the outer diameter of one pipe is the same as the inner diameter of the other pipe, and one end of the two pipes is respectively connected to the first main pipe 1 and the second main pipe 2, and the adjacent ends of the two pipes are slidably connected.

[0030] Specifically, Figure 1-Figure 4As shown, both ends of the first main pipeline 1 and the second main pipeline 2 are sealed structures, that is, the first main pipeline 1 and the second main pipeline 2 are hollow structures. The two ends of the connecting pipe 3 are respectively connected to the first main pipeline 1 and the second main pipeline 2, and a water inlet 31 is provided in the middle of the connecting pipe 3. When in use, water can be input from the water inlet 31, and the input water will be transported to the inside of the first main pipeline 1 and the second main pipeline 2 through the two ends of the connecting pipe 3, and then can be sprayed out from the water spray holes 120 at the top of the first main pipeline 1 and the second main pipeline 2, so as to achieve the effect of extinguishing fire and cooling. It should be noted that the water inlet 31 is set in the middle of the connecting pipe 3, so that the water entering from the water inlet 31 can be more evenly entered into the first main pipeline 1 and the second main pipeline 2 on both sides, reducing the shaking caused by the different pressures on both sides, so that the device can be more stable, which is conducive to fire extinguishing operations.

[0031] Furthermore, if Figure 1 and Figure 2 As shown, the bottom of the first main pipeline 1 is fixedly connected to the first base 11, the bottom of the second main pipeline 2 is fixedly connected to the second base 21, and the bottoms of the first base 11 and the second base 21 are both provided with universal wheels 130. The provision of the first base 11 and the second base 21 can support the first main pipeline 1 and the second main pipeline 2, and prevent the first main pipeline 1 and the second main pipeline 2 from directly contacting the ground, thereby protecting the first main pipeline 1 and the second main pipeline 2. The provision of the universal wheels 130 can reduce the friction between the first base 11 and the second base 21 and the ground, thereby protecting the first base 11 and the second base 21, and also facilitate the movement of the first base 11 and the second base 21.

[0032] In addition, if Figure 1-Figure 4 As shown, the two first sub-pipes 4 are parallel to each other, and one end of the two first sub-pipes 4 is respectively connected to the two ends of the first main pipe 1. In other words, one end of the two first sub-pipes 4 can be connected to the first main pipe 1, so that water can flow between the first main pipe 1 and the first sub-pipes 4.

[0033] In addition, one end of the two second sub-pipes 5 is respectively connected to the two ends of the second main pipe 2, and the two second sub-pipes 5 correspond to the two first sub-pipes 4 one by one, and the other end of the second sub-pipe 5 is slidably connected to the inside of the first sub-pipe 4 through the other end of the corresponding first sub-pipe 4. In other words, one end of the two second sub-pipes 5 can be connected to the second main pipe 2, so that the water flow can flow between the second main pipe 2 and the second sub-pipe 5. Because the other end of the second sub-pipe 5 is slidably connected to the inside of the first sub-pipe 4, the water flow can also flow between the first sub-pipe 4 and the second sub-pipe 5. In this way, a flow path can be formed between the first main pipe 1, the second main pipe 2, the connecting pipe 3, the first sub-pipe 4 and the second sub-pipe 5, so that the water spraying operation can be performed at multiple positions, and the fire extinguishing and cooling of the bottom of the vehicle is more comprehensive. Moreover, the first auxiliary pipe 4 and the second auxiliary pipe 5 are connected by sliding, and since a plurality of water spray holes 120 are provided on the tops of the first auxiliary pipe 4 and the second auxiliary pipe 5, when the first auxiliary pipe 4 and the second auxiliary pipe 5 are separated from each other, more water spray holes 120 on the second auxiliary pipe 5 can be exposed, thereby increasing the number of water spray holes 120 in actual operation and improving the speed of fire extinguishing. In addition, the spraying range of the mobile fire fighting device can be adjusted, which is suitable for various vehicle models and is more flexible and convenient to use.

[0034] Furthermore, if Figure 3 and Figure 4 As shown, the mobile fire fighting device also includes: a plurality of third auxiliary pipes 6 and a plurality of fourth auxiliary pipes 7, the two ends of the third auxiliary pipes 6 are respectively connected to the first auxiliary pipes 4 on both sides, the two ends of the fourth auxiliary pipes 7 are respectively connected to the second auxiliary pipes 5 on both sides, and the tops of the third auxiliary pipes 6 and the fourth auxiliary pipes 7 are both provided with a plurality of water spray holes 120. The third auxiliary pipes 6 and the fourth auxiliary pipes 7 also mainly play the role of communication. The two ends of the third auxiliary pipes 6 are respectively connected to the first auxiliary pipes 4 on both sides, and the two ends of the fourth auxiliary pipes 7 are respectively connected to the second auxiliary pipes 5 on both sides, so that a new flow path can be formed between the first main pipe 1, the second main pipe 2, the connecting pipe 3, the first auxiliary pipe 4, the second auxiliary pipe 5, the plurality of third auxiliary pipes 6 and the plurality of fourth auxiliary pipes 7, thereby further increasing the scope of fire extinguishing and cooling.

[0035] In addition, if Figure 5 As shown, the mobile fire fighting device further includes: two first drive assemblies 9, the two first drive assemblies 9 are in one-to-one correspondence with the two first auxiliary pipes 4 and the two second auxiliary pipes 5, and are used to drive the other end of the corresponding second auxiliary pipe 5 to slide inside the first auxiliary pipe 4. Specifically, the first drive assembly 9 includes: a cylinder 91 and a connecting seat 92, one end of the cylinder 91 is fixedly connected to the first base 11, the telescopic end of the cylinder 91 is fixedly connected to the connecting seat 92, and the connecting seat 92 is fixedly connected to the outer wall of the corresponding second auxiliary pipe 5.

[0036] When in use, in the initial state, the mobile fire fighting device can be placed under the vehicle with the smallest volume, so that the mobile fire fighting device can be arranged as quickly as possible, and there is no need to worry about the size of the vehicle. After the mobile fire fighting device is placed, the volume of the mobile fire fighting device can be expanded according to actual conditions. At this time, the cylinder 91 is started, and the telescopic end of the cylinder 91 will drive the second auxiliary pipe 5 to move toward the side away from the first auxiliary pipe 4 through the connecting seat 92, so that the distance between the first main pipe 1 and the second main pipe 2 can be increased, the fire extinguishing range can be increased, and fire extinguishing and cooling can be achieved at multiple locations of the burning vehicle, especially the bottom of the vehicle where the battery of the electric vehicle is usually installed. By spraying water on the bottom of the vehicle, the battery and its surrounding components can be cooled and protected, thereby improving safety.

[0037] As an optional embodiment, Figure 2 and Figure 8 As shown, the cylinder 91 is arranged below the corresponding first auxiliary pipe 4, and a protective plate 150 is fixedly connected to the first auxiliary pipe 4 to protect both sides of the cylinder 91. Among them, the cylinder 91 is arranged below the corresponding first auxiliary pipe 4, so that the first auxiliary pipe 4 can be used to shield the cylinder 91, reducing the impact of the combustion vehicle on the cylinder 91, which is conducive to the normal operation of the cylinder 91. In addition, the protective plate 150 can prevent the detached combustion parts from contacting the cylinder 91, thereby enabling the cylinder 91 to work better. It should be noted that the use technology of the cylinder 91 is the existing technology, and the cylinder 91 can be extended and retracted by sending instructions to the cylinder 91 through the controller.

[0038] As an optional embodiment, Figure 2 As shown, a plurality of water spray holes 120 are provided with nozzles 110. The provision of the nozzles 110 can control the water flow sprayed from the water spray holes 120. For example, the nozzles 110 can be atomizing nozzles 110, which can further increase the area of ​​water spraying, thereby increasing the fire extinguishing area. The nozzles 110 can also be adjustable nozzles 110, that is, the angle of water spraying can be controlled, so that the direction of water spraying can be more flexible, thereby improving the applicability and flexibility of the device.

[0039] In addition, if Figure 2-Figure 4As shown, the barrier assembly 8 includes a support assembly 81 and a plurality of support rods 82, and the plurality of support rods 82 are rotatably connected to the support assembly 81, and are used to support and barrier the burning and falling parts on the vehicle. The support assembly 81 is connected to the first main pipe 1, and the height of the nozzle 110 from the ground is less than the height of the support rods 82 from the ground. Since the height of the support rods 82 is higher than the nozzle 110, when a smaller part falls off and blocks the water spray hole 120, the water spray hole 120 can push the part away by its own water pressure. When a larger part falls off, and the water pressure of the water spray hole 120 itself is not enough to push the part away, the support rods 82 can support the larger part, thereby reducing the situation where the larger part directly blocks part of the water spray hole 120.

[0040] Specifically, the support assembly 81 includes: a first support plate 811 and a second support plate 812 fixedly connected to both sides of the first base 11, and the first support plate 811 and the second support plate 812 both extend toward one side of the second base 21. A plurality of first mounting plates 813 and a plurality of second mounting plates 814 are fixedly connected to the first support plate 811 and the second support plate 812, respectively, and the first mounting plates 813 and the second mounting plates 814 are arranged opposite to each other. The plurality of first mounting plates 813 and the plurality of second mounting plates 814 each correspond to the plurality of support rods 82 one by one, and the two ends of the support rods 82 are rotatably connected to the corresponding first mounting plates 813 and the corresponding second mounting plates 814, respectively.

[0041] In addition, if Figure 7-9As shown, the mobile fire fighting device also includes a second drive assembly 10, which is used to drive multiple support rods 82 to rotate at the same time. The second drive assembly 10 includes: an L-shaped fixed plate 101, a motor 102 and a transmission shaft 103. The L-shaped fixed plate 101 is divided into a vertical part perpendicular to the ground and a horizontal part parallel to the ground. The top of the vertical part of the fixed plate 101 is fixedly connected to the bottom of the first support plate 811, and one end of the transmission shaft 103 is rotatably connected to the vertical part of the fixed plate 101, and the axis of the transmission shaft 103 is parallel to the axis of the support rod 82. The motor 102 is fixedly connected to the horizontal part of the fixed plate 101, and the motor 102 is fixedly connected to the other end of the transmission shaft 103. The top of the vertical part of the fixed plate 101 is fixedly connected to the bottom of the first support plate 811, and the first support plate 811 can be used to protect the motor 102, so that the motor 102 can work better. A first pulley assembly 104 is connected between the motor 102 and any one of the support rods 82, and a second pulley assembly 105 is connected between two adjacent support rods 82. It should be noted that an annular groove is provided at one end of the support rod 82, and the pulleys in the first pulley assembly 104 and the second pulley assembly 105 are both provided in the annular groove, so that the first pulley assembly 104 and the second pulley assembly 105 can be protected. The belt material in the first pulley assembly 104 and the second pulley assembly 105 can be selected from high temperature resistant EPDM rubber material, and of course other suitable materials can also be selected.

[0042] During use, when a larger component falls onto the support rod 82, the motor 102 is started, and the motor 102 will drive the supporting rod 82 matched with it to rotate through the first pulley assembly 104. The rotation of the support rod 82 can drive the remaining support rods 82 to rotate through the transmission of multiple second pulley assemblies 105, so that multiple support rods 82 can move the larger component out through the friction between the larger component and the support rods 82, so that the component can be cleaned, and the water sprayed from the water spray hole 120 can directly contact the bottom of the vehicle, so as to better extinguish the fire.

[0043] In addition, the first base 11 and the second base 21 are fixedly connected to the end away from the connecting pipe 3 with the first cleaning rod 111 and the second cleaning rod 211 respectively, and the free ends of the first cleaning rod 111 and the second cleaning rod 211 extend toward the end away from the connecting pipe 3 and are close to each other. The first cleaning rod 111 and the second cleaning rod 211 mainly play the role of clearing obstacles. In the initial state, the free ends of the first cleaning rod 111 and the second cleaning rod 211 are close to each other to form a triangle-like structure. When the mobile fire-fighting device is pushed forward, the first cleaning rod 111 and the second cleaning rod 211 will push the obstacles on the way forward to both sides, thereby facilitating the advancement and movement of the mobile fire-fighting device.

[0044] As an optional embodiment, a handle 140 is provided on the connecting pipe 3, and the handle 140 extends in a direction away from the first cleaning rod 111. The setting of the handle 140 allows a person to operate away from the vehicle, and the operator can use the handle 140 to push the water spray hole 120 to the bottom of the vehicle, thereby protecting the operator, and the setting of the handle 140 also makes it easier to control the mobile fire-fighting device.

[0045] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
