[0041] Refer to the attached Figure 1 - attached Figure 8, A quick - install fire - fighting cannon, comprising a cannon body 1 and a fixing mechanism 2. A connecting part 10 is provided on the cannon body 1; the fixing mechanism 2 includes a base 21, clamping jaws 22 and a locking member 23. The connecting part 10 is detachably installed on the base 21; at least two clamping jaws 22 are slidably installed on the base 21, and the two clamping jaws 22 can move relatively closer or farther away; the locking member 23 is installed inside the base 21 and can synchronously lock or loosen the two clamping jaws 22; the cannon body 1 is fixed at a specific position by clamping an object with the two clamping jaws 22.

[0042] Specifically, during use, first find the fire - fighting point, and release the restriction of the locking member 23 on the two clamping jaws 22. Then, adjust the relative distance between the two clamping jaws 22 according to the thickness of the object at the fire - fighting point. After surrounding the object with the two clamping jaws 22, lock the two clamping jaws 22 through the locking member 23, then the base 21 can be fixed on this object; then, fix the cannon body 1 to the base 21 through the connecting part 10, and then connect the water cannon to an external water source to carry out fire - fighting operations; according to the above operations, firefighters can fix the cannon body 1 at different positions to carry out fixed - point fire extinguishing.

[0043] It should be noted that the object clamped by the two clamping jaws 22 can be a wall surface (not shown in the figure), a fixing rack (not shown in the figure), etc., or a corresponding fixing platform can be directly set on a conventional fire truck for the two clamping jaws 22 to clamp, so as to enrich the usage scenarios of this quick - install fire - fighting cannon.

[0044] In summary, the utility model clamps different objects by designing the fixing mechanism 2, so that the cannon body 1 can be fixed at a specific position, improving the usage flexibility; the cooperative design of the base 21, the clamping jaws 22 and the locking member 23 facilitates the disassembly and assembly of the fixing mechanism 2, and further enables firefighters to quickly transfer and fix the cannon body 1 for use, so as to achieve timely rescue and reduce the overall loss.

[0045] Refer to the attached Figure 3 - attached Figure 6 , the connecting part 10 is a clamping post 101 with a jack 1010. A sleeve 211 is provided on the base 21, and a fastening bolt 2110 is threadedly connected to the sleeve 211; the clamping post 101 can be inserted into the sleeve 211, and the fastening bolt 2110 can penetrate through the jack 1010.

[0046] Specifically, during installation, first fix the base 21 to the object, then lift the cannon body 1 to drive the clamping post 101 to be inserted into the sleeve 211, and then penetrate the fastening bolt 2110 through the jack 1010 and tighten it, then the cannon body 1 can be fixed on the base 21 for use; during disassembly and transfer, first remove the fastening bolt 2110, then lift the cannon body 1 to drive the clamping post 101 to disengage from the sleeve 211, and then remove the base 21 from the object, then the whole can be transferred; therefore, the cooperative use of the clamping post 101 and the sleeve 211 facilitates the disassembly and assembly of the cannon body 1 and the base 21.

[0047] See attached Figure 4 -Attached Figure 7 The base 21 is provided with a guide groove 212 with openings at both ends, and a through hole 2120 is opened on the side wall of the guide groove 212; the top ends of the two clamping jaws 22 are provided with guide blocks 220 that slide with the guide groove 212; the locking member 23 includes an auxiliary wheel 231, a rack 232 and a locking bolt 233, two racks 232 are provided and are respectively fixed to the two guide blocks 220, the auxiliary wheel 231 is arranged in the guide groove 212 and synchronously meshes with the two racks 232, one end of the locking bolt 233 is provided with a butt joint 2330 placed in the through hole 2120, and the other end of the locking bolt 233 can rotatably pass through the axis of the auxiliary wheel 231 and be threadedly connected to the base 21, and rotating the locking bolt 233 can drive the butt joint 2330 to tighten or loosen the auxiliary wheel 231.

[0048] Specifically, when the relative distance between the two clamping jaws 22 needs to be adjusted to adapt to walls of different thicknesses, the locking bolt 233 is rotated to allow the abutment 2330 to loosen the auxiliary wheel 231. At this time, the auxiliary wheel 231 can rotate to ensure that the two racks 232 have the ability to move. Firefighters can move any clamping jaw 22 along the length direction of the guide groove 212 to adjust the clamping space. After the adjustment is completed, the locking bolt 233 is twisted to press against the auxiliary wheel 231 to limit the movement of the two racks 232, thereby locking the two clamping jaws 22 in the current position.

[0049] Among them, the coordinated use of the auxiliary wheel 231 and the rack 232 allows the two clamping jaws 22 to move closer to or away from each other synchronously, improving the convenience of adjustment, and the design of the locking bolt 233 facilitates the quick locking or loosening of the auxiliary wheel 231, making the disassembly and installation of the base 21 easier.

[0050] In addition, the abutment 2330 can be designed to be hexagonal, or a tool slot can be set on the abutment 2330. By inserting a tool such as a hexagonal pliers or a screwdriver into the through hole 2120 and inserting the abutment 2330 or the tool slot, the lock bolt 233 can be turned.

[0051] See attached Figure 6 -Attached Figure 7 Considering that the clamped object may have an uneven surface, in this case, it is difficult for the two clamping jaws 22 to fit the object tightly, resulting in the possibility of shaking of the base 21 after installation; to solve this problem, in the utility model, the two clamping jaws 22 are both threadedly connected with a horizontally arranged first limit bolt 221, and the two first limit bolts 221 can be relatively close to or far away from each other.

[0052] Specifically, after the two clamping jaws 22 clamp an object, the two first limit bolts 221 can be screwed to move closer to each other to further press against the front and back / left and right sides of the object, so that the two clamping jaws 22 can adapt to the uneven surface of the object through the two first limit bolts 221, avoiding the shaking of the base 21 after installation and further improving the installation stability; during disassembly, first screw the two first limit bolts 221 away from each other to disengage from the object, and then adjust the two clamping jaws 22 to move relatively away from each other, and the base 21 can be removed from the object.

[0053] Refer to the appendix Figure 6 - appendix Figure 7 Considering that there is no cooperation between the two clamping jaws 22 and the bottom of the object, during actual use, with the vibration of the water cannon, the two clamping jaws 22 may move upward and fall off the object; to solve this problem, in the present utility model, abutting blocks 223 parallel to the base 21 are provided at the upper ends of the two clamping jaws 22, the two abutting blocks 223 extend inward, and vertically arranged second limit bolts 222 are threadedly connected to the two abutting blocks 223, and the two second limit bolts 222 can move closer to or away from the base 21.

[0054] Specifically, after the two clamping jaws 22 clamp an object, the two second limit bolts 222 can be screwed to move closer to each other to further press against the bottom side of the object. Under the combined action of the clamping jaws 22, the base 21 and the second limit bolts 222, the movement of the base 21 in the horizontal and vertical directions can be restricted, avoiding the clamping jaws 22 from detaching from the object and further improving the installation stability; during disassembly, first screw the two second limit bolts 222 away from the base 21, and then adjust the two clamping jaws 22 to move relatively away from each other, and the base 21 can be removed from the object.

[0055] It should be noted that in some special cases, such as when the clamped object is a columnar body, the first limit bolts 221 and the second limit bolts 222 can also be used in combination.

[0056] Refer to the appendix Figure 9 - appendix Figure 12 A fire truck includes a vehicle body 3 and a quick-installation fire cannon. The cannon body 1 is detachably installed on the vehicle body 3 through a fixing mechanism 2; under this design, the water cannon can be placed on the vehicle body 3, facilitating the long-distance transfer of the water cannon.

[0057] Refer to the appendix Figure 9 - appendix Figure 12 Regarding the fixing method between the fixing mechanism 2 and the vehicle body 3, there are various ways, and the present utility model does not limit this. For the convenience of understanding, in this embodiment, an activity cavity 30 is provided inside the vehicle body 3, at least two rotation grooves 301 communicating with the outside are opened on the side wall of the activity cavity 30, notches 302 are provided at the two rotation grooves 301, and the widths of the two rotation grooves 301 are both smaller than the widths of the notches 302 and the abutting blocks 223.

[0058] Specifically, before use, first rotate and adjust the position of the second adjusting bolt so that the distance from the second adjusting bolt to the base 21 is equal to or slightly greater than the thickness of the side wall of the movable cavity 30. Then, respectively insert the abutting blocks 223 on the two clamping jaws 22 into the movable cavity 30 through the two notches 302. Next, rotate the base 21 to drive the two clamping jaws 22 to move along the two rotating grooves 301 respectively, so that the two abutting blocks 223 are synchronously staggered from the two notches 302. At this time, the second limiting bolt 222 can abut against the side wall of the movable cavity 30, and the base 21 can be fixed on the vehicle body 3.

[0059] Refer to the appendix Figure 9 - appendix Figure 12 There are various types of vehicle bodies 3, such as conventional driving vehicles or driverless vehicles. Considering the high temperature at the fire scene, a driverless vehicle is preferably used. Among them, the driverless vehicle includes a vehicle shell 31, a driving unit 32, and a control unit 33; the movable cavity 30, the rotating grooves 301, and the notches 302 are all arranged on the vehicle shell 31, and crawler belts 34 are installed on both sides of the vehicle shell 31; the driving unit 32 is installed inside the vehicle shell 31 and is drivingly connected to the crawler belts 34, and the control unit 33 is installed inside the vehicle shell 31 and is electrically connected to the driving unit 32.

[0060] Specifically, during use, by sending an instruction from the control unit 33 to the driving unit 32, the crawler belts 34 can be driven to operate, and then the driverless vehicle can drive the gun body 1 to move to a suitable position; among them, for the convenience of firefighters' operation, the control unit 33 may include a signal receiving module. By sending an instruction to the control unit 33 through a remote control device such as a remote controller or a mobile phone (not shown in the figure), the movement of the driverless vehicle can be controlled.

[0061] It should be noted that the driverless vehicle is an existing product, so the internal structure thereof is not further elaborated in the present utility model. For the convenience of understanding, the driving unit 32 includes a servo motor 321 and a transmission shaft 322, and the servo motor 321 drives the crawler belts 34 through the transmission shaft 322; on the other hand, the technology of controlling the driving unit 32 by sending an instruction to the control unit 33 through a remote control device also belongs to the existing technology, so the working principle and specific circuit structure thereof are not elaborated in detail in this embodiment.

[0062] Furthermore, in order to reduce costs, the crawler belts 34 can also be replaced with ordinary wheels (not shown in the figure).

[0063] Refer to the appendix Figure 9 - appendix Figure 12, currently, most of the gun bodies 1 on the market are manually adjustable guns, which require firefighters to manually adjust the water spraying direction, and it is inconvenient to use in combination with unmanned vehicles. Therefore, the gun body 1 in the present utility model preferably adopts an electric adjustable gun. The electric adjustable gun includes a base 11, a water inlet pipe 12, a conduit 13, a nozzle 14, a first adjusting part 15 and a second adjusting part 16; a connecting part 10 and the water inlet pipe 12 are both arranged on the base 11; the conduit 13 is rotatably connected to the base 11, and the conduit 13 is connected to the water inlet pipe 12, and the first adjusting part 15 is installed at the connection between the conduit 13 and the base 11 and is used to drive the conduit 13 to rotate around the base 11; the nozzle 14 is rotatably connected to the conduit 13, and the nozzle 14 is connected to the conduit 13, and the second adjusting part 16 is installed at the connection between the nozzle 14 and the conduit 13 and is used to drive the nozzle 14 to rotate around the conduit 13.

[0064] Specifically, during use, an external water supply device (not shown in the figure) is connected to the water inlet pipe 12 for water supply. By using the first adjusting part 15 and the second adjusting part 16 in cooperation, the water spraying range of the nozzle 14 is adjusted to improve the degree of automation.

[0065] Refer to the appendix Figure 9 - appendix Figure 12 , a signal socket 310 electrically connected to the control unit 33 is further provided on the vehicle body 31. Both the first adjusting part 15 and the second adjusting part 16 can be plugged into the signal socket 310 through wires (not shown in the figure); therefore, the design of the signal socket 310 not only facilitates power supply to the first adjusting part 15 and the second adjusting part 16, but also enables firefighters to directly remotely control the operation of the first adjusting part 15 and the second adjusting part 16 through the control unit 33, improving the convenience of use.

[0066] Refer to the appendix Figure 9 - appendix Figure 12 , the structures of the first adjusting part 15 and the second adjusting part 16 are diverse, and the present utility model does not limit this. For the convenience of understanding, in this embodiment, the first adjusting part 15 includes a first motor 151, a worm 152 and a turbine 153. The turbine 153 is installed on the conduit 13, and the first motor 151 is installed on the base 11 and drives the turbine 153 through the worm 152; the second adjusting part 16 includes a second motor 161, a gear 162 and a tooth block 163. The tooth block 163 is installed on the nozzle 14, and the second motor 161 is installed on the conduit 13 and drives the tooth block 163 through the gear 162.

[0067] Specifically, during use, the first motor 151 is started to drive the worm 152, and then the turbine 153 and the conduit 13 rotate. The second motor 161 is started to drive the gear 162, and then the tooth block 163 and the nozzle 14 rotate. By using the two in cooperation, the orientation of the nozzle 14 can be adjusted at multiple angles.

[0068] Refer to the appendix Figure 9-Appendix Figure 12 A first camera 31s for identifying road conditions is installed on the vehicle body 31, and the first camera 31s is electrically connected to the control unit 33; a second camera 14s for monitoring fire sources is installed on the nozzle 14, and the second camera 14s can be plugged into the signal socket 310 through an electric wire; the combined use of the first camera 31s and the second camera 14s facilitates firefighters to observe the fire scene, enabling the gun body 1 to accurately dock at a suitable location and enabling the water ejected by the gun body 1 to accurately hit the fire source.

[0069] It should also be noted that although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
