[0071] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.
[0072] First embodiment
[0073] The utility model provides a spray unit 100. The spray unit 100 is used for a fire extinguishing device. The fire extinguishing device is surrounded by the spray unit 100 on the outside of the burning object, and sprays a fire extinguishing medium on the object, thereby extinguishing the fire. This article takes the fire extinguishing medium as water as an example for explanation. This article takes a car (such as an electric car) as an example for explanation as the object to be extinguished.
[0074] Please refer to Figures 1 to 13The spray unit 100 includes two frames 110 and a frame spray head 154. The two frames 110 include a first frame 113 and a second frame 114. The frame 110 has a frame internal passage and a frame hole connected to the frame internal passage. The frame hole can be provided with a frame spray head 154. The frame spray head 154 is connected to the frame internal passage. The frame spray head 154 has a frame spray hole 156 facing the inside of the spray unit 100. In this way, water can be sprayed toward the inside of the spray unit 100 through the frame spray hole 156.
[0075] It should be noted that when the spray unit 100 is in an extended state described below, the interior space of the rectangular parallelepiped structure formed by the first frame 113 , the second frame 114 , and the telescopic assembly 120 described below is the interior of the spray unit 100 .
[0076] It is understood that in an embodiment not shown, the frame hole may be configured as a frame spray hole, in which case no frame spray head may be provided.
[0077] like Figure 1 and Figure 5 As shown, the spray unit 100 further includes a telescopic assembly 120. The telescopic assembly 120 can be telescoped along a telescopic direction D1. One end of the telescopic assembly 120 is connected to one frame 110. The other end of the telescopic assembly 120 is connected to another frame 110. In this way, the telescopic assembly 120 is telescoped along the telescopic direction D1, so that the spray unit 100 can have an extended state and a stacked state.
[0078] like Figure 1 and Figure 5 As shown, when the spray unit 100 is in the extended state, the maximum dimension between the first frame 113 and the second frame 114 along the extension direction D1 is the extended dimension. Figure 6 and Fig.10 As shown, when the spray unit 100 is in a stacked state, the maximum dimension between the first frame 113 and the second frame 114 along the telescopic direction D1 is the stacking dimension. The elongated dimension is greater than the stacking dimension.
[0079] In this way, the spray unit 100 can be in an extended state, and can cover the vehicle body 190 as much as possible, so that the fire can be effectively extinguished. When the spray unit 100 is in a stacked state, it is convenient to store the spray unit 100.
[0080] like Figure 1 and Fig. 9As shown, the spray unit 100 further includes a bottom fire extinguishing assembly 130. The bottom fire extinguishing assembly 130 is detachably connected to the frame 110. The bottom fire extinguishing assembly 130 extends to the bottom area of the frame 110 and extends along the telescopic direction D1. The bottom fire extinguishing assembly 130 is used to extend to the bottom of the vehicle body 190 of the automobile. The bottom fire extinguishing assembly 130 has a bottom spray hole 133 facing the inside of the spray unit 100. In this way, when the spray unit 100 is surrounded on the outside of the vehicle body 190, the bottom fire extinguishing assembly 130 is located below the vehicle body 190. The bottom fire extinguishing assembly 130 can spray water to the lower surface of the vehicle body 190 through the bottom spray hole 133, thereby extinguishing the fire.
[0081] Those skilled in the art will appreciate that a battery pack is disposed below the vehicle body 190. The bottom fire extinguishing assembly 130 can directly spray water toward the battery pack, thereby directly extinguishing the fire in the battery pack.
[0082] In this embodiment, the telescopic assembly 120 enables the two frames 110 to move relative to each other along the telescopic direction D1, so that the spray unit 100 is in an extended state, and the spray unit 100 can be arranged around the outside of the vehicle body 190, so as to spray the fire extinguishing medium onto the vehicle body 190; in addition, the bottom fire extinguishing assembly 130 can be arranged under the vehicle body 190 to spray the fire extinguishing medium onto the lower surface of the vehicle body 190, thereby directly extinguishing the fire on the lower surface of the vehicle, and quickly extinguishing the fire on the vehicle.
[0083] Alternatively, if Figure 1 and Figure 5 As shown, the frame 110 includes a vertical tube 111 and a horizontal tube 112. The vertical tube 111 and the horizontal tube 112 are tubular structures. The length direction D2 of the vertical tube 111 extends in the vertical direction. The horizontal tube 112 is connected to the top of the vertical tube 111. The internal channel of the horizontal tube 112 is connected to the internal channel of the vertical tube 111 to form the internal channel of the frame. Therefore, the structure of the frame 110 is simple.
[0084] Further preferably, the frame 110 is constructed as a U-shaped structure. The opening of the U-shaped structure faces the bottom surface. Thus, the U-shaped structure can be arranged outside the vehicle body 190 to facilitate fire extinguishing of the vehicle body 190.
[0085] Furthermore, both the horizontal pipe 112 and the vertical pipe 111 are designed with frame nozzles 154. Thus, the spraying area of the frame 110 is larger.
[0086] like Figure 1 As shown, the frame nozzle 154 is a columnar structure. The angle between the axial direction and the horizontal direction of the frame nozzle 154 is 30° to 50°. Therefore, the spraying area of the frame nozzle 154 is large, and the fire can be extinguished more effectively.
[0087] Furthermore, the angle between the axial direction and the horizontal direction of the frame nozzle 154 is 45°.
[0088] Furthermore, each frame nozzle 154 has a plurality of frame spray holes 156. The plurality of frame spray holes 156 of each frame nozzle 154 are circumferentially spaced around the axis of the tube on which the frame nozzle 154 is disposed. Specifically, the plurality of frame spray holes 156 of the frame nozzle 154 disposed on the transverse tube 112 are circumferentially spaced around the axis of the transverse tube 112. The plurality of frame spray holes 156 of the frame nozzle 154 disposed on the vertical tube 111 are circumferentially spaced around the axis of the vertical tube 111. In this way, the frame nozzle 154 sprays water in a fan shape, and the fan-shaped water covers a large area, which can more conveniently extinguish fires.
[0089] like Figure 1 and Figure 5 As shown, the telescopic assembly 120 includes a scissor-type telescopic structure. The scissor-type telescopic structure is a scissor-type telescopic structure of the prior art. It will not be repeated here. Therefore, the telescopic assembly 120 has a simple structure and high strength.
[0090] Please continue to refer to Figure 1 and Figure 5 The telescopic assembly 120 includes a top telescopic assembly 121 and a side telescopic assembly 122. Along the telescopic direction D1, one end of the top telescopic assembly 121 is connected to the transverse tube 112 of the first frame 113, and the other end of the top telescopic assembly 121 is connected to the transverse tube 112 of the second frame 114. Along the telescopic direction D1, one end of the side telescopic assembly 122 is connected to the vertical tube 111 of the first frame 113, and the other end of the side telescopic assembly 122 is connected to the vertical tube 111 of the second frame 114. In this way, the spray unit 100 can be stably switched between the extended state and the stacked state.
[0091] For further information, please refer to Figure 1 and Figure 5 The spray unit 100 further includes a sliding connection 158. Part of the sliding connection 158 is movably mounted on the transverse tube 112 along the length direction D3 of the transverse tube 112. The part of the sliding connection 158 is also connected to the end of the top telescopic assembly 121 along the telescopic direction D1. This allows the top telescopic assembly 121 to move relative to the transverse tube 112 along the length direction D3 of the transverse tube 112. This facilitates the connection between the top telescopic assembly 121 and the transverse tube 112.
[0092] like Figure 1 , Figures 3 to 5As shown, the spray unit 100 further includes a fixed connector 157. The fixed connector 157 is sleeved on the vertical pipe 111. The fixed connector 157 is fixedly disposed on the vertical pipe 111. The fixed connector 157 is also connected to a portion of the end of the side telescopic assembly 122 along the telescopic direction D1. Another portion of the sliding connector 158 is sleeved on the vertical pipe 111 so as to be movable relative to the vertical pipe 111 along the length direction D2 of the vertical pipe 111. This portion of the sliding connector 158 is also connected to another portion of the end of the side telescopic assembly 122 along the telescopic direction D1. Thus, the connection between the end telescopic assembly 120 and the frame 110 is facilitated.
[0093] Alternatively, if Figure 1 As shown, the bottom fire extinguishing assembly 130 includes a vertical pipe 131 and a bottom pipe 132. Both the vertical pipe 131 and the bottom pipe 132 are tubular structures. The length direction of the vertical pipe 131 is parallel to the vertical direction. The length direction of the bottom pipe 132 extends along the telescopic direction D1. The top end of the vertical pipe 131 is connected to the cross pipe 112 so that the internal channel of the vertical pipe 131 is connected to the internal channel of the cross pipe 112. The bottom pipe 132 is connected to the bottom end of the vertical pipe 131 so that the internal channel of the bottom pipe 132 is connected to the internal channel of the vertical pipe 131. The bottom pipe 132 is used to extend to the bottom of the vehicle body 190. The bottom pipe 132 includes a bottom spray hole 133. The bottom spray hole 133 faces the inside of the spray unit 100. In this way, water can be sprayed toward the inside of the spray unit 100 through the bottom spray hole 133, so as to extinguish the fire of the vehicle body 190. As a result, the structure of the bottom fire extinguishing assembly 130 is simple.
[0094] Furthermore, if Figure 1 and Figure 2 As shown, the bottom pipe 132 includes a plurality of groups of bottom spray holes 133. The plurality of groups of bottom spray holes 133 are spaced apart along the length direction of the bottom pipe 132. Each group of bottom spray holes 133 includes a plurality of bottom spray holes 133. The plurality of bottom spray holes 133 of each group of bottom spray holes 133 are circumferentially arranged on the bottom pipe 132 around the axis of the bottom pipe 132. Thus, the plurality of bottom spray holes 133 can spray water in a fan shape, the center line of the fan shape being perpendicular to the vertical direction. In this way, fire can be extinguished more conveniently.
[0095] Furthermore, the angle between the axes of two adjacent spray holes in each group of bottom spray holes 133 in the circumferential direction around the axis of the bottom tube 132 is in the range of 10° to 20°. In this way, fire extinguishing can be more convenient.
[0096] Furthermore, the angle between the axes of two adjacent spray holes in each group of bottom spray holes 133 in the circumferential direction around the axis of the bottom tube 132 is in the range of 15°.
[0097] Optionally, return Figure 1 and Figure 5The spray unit 100 further includes a moving wheel 152 and an auxiliary wheel 153. The moving wheel 152 is disposed at the bottom end of the vertical pipe 111. Thus, the frame 110 is conveniently moved along the telescopic direction D1.
[0098] The auxiliary wheels 153 are connected to the bottom tube 132 to support the bottom tube 132, thereby preventing the bottom tube 132 from bending and deforming downward. When the frame 110 moves, the auxiliary wheels 153 can also assist the bottom fire extinguishing assembly 130 to move smoothly.
[0099] Alternatively, if Figure 1 As shown, along the length direction D3 of the transverse tube 112, the bottom fire extinguishing assembly 130 is located at a substantially middle portion of the transverse tube 112. Thus, fire can be extinguished more effectively.
[0100] like Figure 1 , Figures 5 to 13 As shown, the spray unit 100 further includes a fireproof cloth 140. The fireproof cloth 140 is connected to the frame 110. The fireproof cloth 140 has a rolled state and an unfolded state. The fireproof cloth 140 in the rolled state is rolled into a roll structure. Thus, the spray unit 100 is conveniently stored.
[0101] The fireproof cloth 140 in the unfolded state is spread out as a whole. At this time, the fireproof cloth 140 covers at least part of the side and end of the sprinkler unit 100. Thus, the fireproof cloth 140 isolates the burning vehicle inside the sprinkler unit 100, which can reduce the spread of the fire.
[0102] Further, the fireproof cloth 140 includes a side fireproof cloth 142 and an end fireproof cloth 141. The axial direction of the side fireproof cloth 142 in the rolled state is parallel to the length direction D2 of the riser 111. The side fireproof cloth 142 is located on the side of the sprinkler unit 100. The side fireproof cloth 142 in the rolled state is connected to the riser 111 of a frame 110. When the sprinkler unit 100 is in the extended state, the side fireproof cloth 142 in the unfolded state covers the side part of the sprinkler unit 100. At this time, the side fireproof cloth 142 extends upward from the ground. The plane where the side fireproof cloth 142 is located is perpendicular to the length direction D3 of the transverse tube 112. The side fireproof cloth 142 is connected to the riser 111 of the first frame 113 and the riser 111 of the second frame 114. Thereby, it is possible to prevent the fire from spreading to the outside of the sprinkler unit 100 along the length direction D3 of the transverse tube 112.
[0103] The axial direction of the end fireproof cloth 141 in the wound state is parallel to the length direction D3 of the cross tube 112. There is a gap between the end fireproof cloth 141 in the wound state and the ground. The axis of the end fireproof cloth 141 in the wound state is located at the water inlet joint 151 described later. The end fireproof cloth 141 connects the two vertical pipes 111 of the first frame 113. The side fireproof cloth 142 in the unfolded state covers the end portion of the sprinkler unit 100. At this time, the end fireproof cloth 141 extends upward from the ground. The plane where the end fireproof cloth 141 is located is perpendicular to the telescopic direction D1. In this way, it is possible to prevent the fire from spreading to the outside of the sprinkler unit 100 along the telescopic direction D1 of the cross tube 112.
[0104] like Figure 6 and Fig.10 As shown, the side fireproof cloth 142 in a rolled state is located inside the spray unit 100. The end fireproof cloth 141 in a rolled state is located outside the spray unit 100. Thus, the spray unit 100 is conveniently stacked.
[0105] like Figure 3 and Figure 4 As shown, the spray unit 100 also includes a cloth connecting portion. The cloth connecting portion has a first clamping wall 161 and a second clamping wall 162. The first clamping wall 161 and the second clamping wall 162 are arranged at intervals. The cloth connecting portion can be fixedly arranged on the vertical pipe 111. The fireproof cloth 140 can be clamped between the first clamping wall 161 and the second clamping wall 162. In this way, the first clamping wall 161 and the second clamping wall 162 clamp the fireproof cloth 140. Thereby, it is convenient to fix the unfolded fireproof cloth 140.
[0106] Specifically, Figure 3 and Figure 4 As shown, the cloth connection part includes an end cloth connection part 160 and a side cloth connection part 163. The first clamping wall 161 and the second clamping wall 162 of the end cloth connection part 160 are perpendicular to the length direction D3 of the cross tube 112. The first clamping wall 161 and the second clamping wall 162 of the side cloth connection part 163 are perpendicular to the expansion and contraction direction D1 of the cross tube 112.
