DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] See also Figure 1 The embodiments of this specification provide a fire extinguisher switch, which may include:

[0028] The fire extinguisher handle fixing member 100 includes at least: a fixing plate and baffles on both sides. The fixing plate abuts against the upper surface of the fire extinguisher upper handle 310; the fixing plate is also provided with a rotation axis limiting holes 104 on both sides. The rotation axis limiting holes 104 are used to limit the rotation connection axis 212 of the fire extinguisher handle fixing member 100 and the connecting arm assembly;

[0029] The connecting arm assembly includes two connecting arms 200 arranged in parallel, a first connecting shaft 211 having its two ends perpendicularly connected to the two connecting arms 200, and a third connecting shaft 214 having its two ends perpendicularly connected to the two connecting arms 200. A first limiting hole 202 is provided at the upper end of each connecting arm 200 to constrain the first connecting shaft 211; an intermediate limiting hole 204 corresponding to the rotating shaft limiting hole 104 is provided at the middle portion of each connecting arm 200; a lower handle limiting hole 206 is provided at the lower portion of each connecting arm 200 to constrain the third connecting shaft 214. The third connecting shaft 214 abuts against the lower surface of the lower handle 320 of the fire extinguisher.

[0030] The push rod 120 has its bottom rotatably connected to the middle of the first connecting shaft 211; the top of the push rod 120 is rotatably connected to the fixing plate, and its connection position is closer to the opening end of the fire extinguisher 300 than the rotating connecting shaft 212, so that when the push rod 120 is extended or retracted, the fire extinguisher handle fixing part 100 and the connecting arm group rotate with the rotating connecting shaft 212 as the rotation center.

[0031] For the convenience of explanation, in this specification, the large opening of the handle of the fire extinguisher 300 is defined as the rear end, and the top of the handle of the fire extinguisher 300 is defined as the front end, and this is used as the reference for the front and back directions.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4. In this embodiment, the fire extinguisher handle fixing part 100 is used to fix the fire extinguisher upper handle 310. The fixing plate is in contact with the upper surface of the fire extinguisher upper handle 310. The fixing plate can be a sheet metal part or a wooden part or a plastic part, etc., which is not specifically limited here. Preferably, the fixing part is a sheet metal part. The fixing plate and the baffles on both sides can be integrated or can be separable parts. The baffles on both sides can prevent the fire extinguisher upper handle 310 from being displaced left and right relative to the fixing plate.

[0033] In this embodiment, the upper surface of the fixing plate is further provided with rotational axis limiting holes 104 on both sides. These rotational axis limiting holes 104 are used to limit the rotational connection axis 212 between the fire extinguisher handle fixing member 100 and the connecting arm assembly. The fire extinguisher handle fixing member 100 and the connecting arm assembly can be folded and unfolded around this rotational axis. Preferably, the rotational axis limiting holes 104 are located in the front half of the fixing member.

[0034] See also Figure 6 . In this embodiment, the connecting arm group may include two parallel and identically shaped connecting arms 200. The two connecting arms 200 may be connected by at least three connecting shafts. Specifically, the top of the connecting arm 200 is provided with a mounting hole, which may also be referred to as the first limiting hole 202, and the first connecting shaft 211 passes through the two mounting holes to connect the two connecting arms 200. An intermediate limiting hole 204 corresponding to the rotating shaft limiting hole 104 is provided in the middle of the two connecting arms 200, and the connecting shaft passing through the two intermediate limiting holes 204 and the two rotating shaft limiting holes 104 to connect the two connecting arms 200 is the rotating connecting shaft 212. A lower handle limiting hole 206 is provided at the lower part of the connecting arm 200 to constrain the third connecting shaft 214, and the third connecting shaft 214 abuts against the lower surface of the lower handle 320 of the fire extinguisher.

[0035] In this embodiment, the push rod 120 may refer to an electric push rod 120. The extension and retraction of the electric push rod 120 may be controlled by a remote signal connection, or by an electrical connection. The bottom of the push rod 120 is rotatably connected to the middle of the first connecting shaft 211; the top of the push rod 120 is rotatably connected to the fixing plate. In this way, the fire extinguisher handle fixing member 100 and the connecting arm group can be folded and unfolded when the push rod 120 is extended or retracted. Specifically, the fire extinguisher handle fixing member 100 presses the fire extinguisher upper handle 310, and the third connecting shaft 214 lifts the fire extinguisher lower handle 320 to press the handle of the fire extinguisher 300.

[0036] In this embodiment, a limiting circular tube 220 may be sleeved on the middle portion of each connecting shaft. The limiting circular tube 220 facilitates the rotational connection between the push rod 120 and the connecting shaft, facilitates the contact between the connecting shaft and the lower surface of the lower handle, and can also limit the distance between the two connecting arms 200.

[0037] See also Figure 5 . The fire extinguisher switch provided by the above embodiment has extremely high compatibility and versatility, low cost, simple and easy operation, is compatible with most fire extinguisher 300 handles, and can also be controlled by remote operation to press the handle of the fire extinguisher 300. In this intelligent fire extinguisher switch, the lower handle limit hole 206 of the connecting arm 200 can be determined according to the size of the fire extinguisher 300 handle, which is flexible and universal. The fire extinguisher handle fixing part 100 of the fire extinguisher switch is used to cover the upper handle of the fire extinguisher 300, which can also be called the upper pressure handle. The fire extinguisher handle fixing part 100 can be tightened with a butterfly screw. The push rod 120 can be an electronic push rod 120, and the electronic push rod 120 can be expanded or retracted according to remote operation to drive the movement of the connecting arm group. The structural shape of the intelligent fire extinguisher switch is a cross type with a middle cross hole in the middle. Two washers 240 can be placed between the connecting arm group and the fire extinguisher handle fixing part 100 to reduce contact friction and cause jamming. When in use, the lower handle screw 230 can be removed first, and the limiting circular tube 220 and the bolt 210 will also be separated; after the whole is inserted into the handle of the fire extinguisher 300, the lower handle screw 230 is then inserted, and the limiting circular tube 220 is also passed through, and then passed through the lower handle to achieve the desired effect. In this embodiment, the connecting shaft can be composed of the bolt 210 and the screw 230.

[0038] In one embodiment, a limiting circular tube 220 is sleeved around the middle of each connecting shaft. Specifically, the connecting shaft may include one of the following: the rotating connecting shaft 212, the first connecting shaft 211, the third connecting shaft 214, or the fourth connecting shaft. The limiting circular tube 220 facilitates the rotational connection between the push rod 120 and the connecting shaft and also limits the distance between the two connecting arms 200. Furthermore, the positioning of the limiting circular tube 220 on the third connecting shaft 214 helps reduce direct pressure against the lower handle 320 of the fire extinguisher.

[0039] In one embodiment, each connecting arm 200 has two or more intermediate limiting holes 204. Multiple intermediate limiting holes 204 can adjust the relative position of the rotating connecting shaft 212 and the connecting arm 200 to improve the applicability of the fire extinguisher switch. Figure 6 Preferably, each connecting arm 200 has three intermediate limiting holes 204 .

[0040] In one embodiment, the number of the lower handle limiting holes 206 of each connecting arm 200 is two or more. The multiple lower handle limiting holes 206 can be applied to different lower handles of the fire extinguisher 300 to improve the applicability of the fire extinguisher switch. Figure 6 Preferably, each connecting arm 200 has five lower handle limiting holes 206 .

[0041] In one embodiment, two symmetrical protruding hanging holes are provided on the fixing plate, a fourth connecting shaft 213 is constrained in the hanging holes, and the top of the push rod 120 is rotatably connected to the middle of the fourth connecting shaft 213 .

[0042] In this embodiment, the hanging hole can serve as a stopper to limit the position of the fourth connecting shaft 213. The top of the push rod 120 can be rotatably connected to the middle of the fourth connecting shaft 213 to transmit force. In this embodiment, the hanging hole can be located in the front half of the fixing plate. Preferably, the hanging holes are located on both sides of the front half of the fixing plate.

[0043] In one embodiment, two symmetrical protruding grooves 113 are provided on the fixing plate, and both ends of the fourth connecting shaft 213 are respectively located in the grooves 113 , and the top of the push rod 120 is rotatably connected to the middle of the fourth connecting shaft 213 .

[0044] In this embodiment, both ends of the fourth connecting shaft 213 are respectively located in the slide groove 113 and can slide in the slide groove 113. In this embodiment, the practical slide groove 113 replaces the hanging hole in the above-mentioned embodiment to facilitate assembly and improve the error during assembly.

[0045] In one embodiment, a threaded hole 112 is further provided on the fixing plate, so that a butterfly screw can be screwed into the threaded hole 112 to press the fixing plate tightly.

[0053] In this embodiment, only the differences from the previous embodiment are described. Other contents can be explained by referring to the contents of the previous embodiment and will not be repeated here.

[0054] It should be noted that the fire extinguisher switch provided in this specification is not limited to fire extinguishing robots but can also be used in other fire extinguishing equipment. Specifically, the application of the fire extinguisher switch is not limited to the above examples. Based on the technical essence of this application, those skilled in the art may make other modifications. However, as long as the functions and effects achieved are the same or similar to those of this application, they shall be covered by the scope of protection of this application.

[0055] The embodiments of this specification also provide a fire extinguishing method, characterized in that it is applied to a fire extinguishing robot, and the method includes:

[0056] Obtaining position information of at least one fire extinguisher 300; wherein the fire extinguisher 300 is mounted on the fire extinguishing robot; each fire extinguisher 300 is equipped with a fire extinguisher switch as described above, and the fire extinguishing robot is electrically connected to the fire extinguisher switch; the position information includes relative position information and direction information of the fire extinguisher 300; the relative position information is used to represent the relative position of the nozzle of the fire extinguisher 300 and the reference center of the fire extinguishing robot;

[0057] Determining fire extinguishing path information of the fire extinguishing robot based on the fire source information;

[0058] When the distance between the fire extinguisher 300 and the fire source is less than or equal to a preset threshold and the fire extinguisher 300 is pointing toward the fire source, a fire extinguishing signal is sent to the fire extinguisher switch to control the push rod 120 to extend.

[0059] In this embodiment, the fire-fighting robot can carry at least one fire extinguisher 300. The fire-fighting robot 300 can be equipped with a positioning system that can obtain the coordinates of the robot's reference center. The robot's reference center can serve as its position information. The position information of the fire extinguisher 300 is determined based on the installation position and size of the fire extinguisher 300 when the fire extinguisher 300 is installed on the robot.

[0060] In this embodiment, the position information of the fire extinguisher 300 may include the position coordinate information and orientation of the fire extinguisher 300. The position coordinate information may be determined based on the reference center position of the fire extinguisher 300 and the relative position information of the two. The inherent properties of the fire extinguisher 300 include an optimal fire extinguishing distance.

[0061] In this embodiment, the fire-fighting robot's processor can determine optimal path information based on the fire source information. Specifically, for example, if the fire source information is an ignition source, the fire-fighting robot determines the robot's destination and parking direction based on the fire source's location and optimal fire-fighting distance. Upon reaching the designated destination, the robot sends a fire-fighting signal to the fire extinguisher switch. In this embodiment, the fire source information can include the fire source's location and temperature.

[0062] In this embodiment, when the distance between the fire extinguisher 300 and the fire source is less than or equal to a preset threshold and the fire extinguisher 300 is pointing towards the fire source, a fire extinguishing signal is sent to the fire extinguisher switch to control the push rod 120 to extend.

[0063] Through the above implementation, the fire-fighting robot can automatically and accurately extinguish fires.

[0064] In this embodiment, only the differences from the previous embodiment are described. Other contents can be explained by referring to the contents of the previous embodiment and will not be repeated here.
