[0003] However, only one water hose is installed on the tracked water-taking robot, one end of the water hose is connected to a water supply tank of the fire truck, and the other end is connected to a water pumping mechanism on the water-taking robot. The length of the water hose is constant, which causes the water hose to be unable to be fully discharged when the water-taking robot needs to move a short distance, and the water hose that cannot be discharged has a large number of bends, which makes it difficult to deliver water.

DETAILED DESCRIPTION​​​

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Embodiment: The present invention provides an all-terrain crawler water-fetching robot for fire trucks, such as Figures 1-3 As shown, it includes a storage box 1, multiple water hoses 2, a quick-change mechanism 4, a water supply hose 5, a three-way ball valve 6, a crawler walking mechanism 7 and a valve switching mechanism 8. The storage box 1 is fixedly installed in the crawler walking mechanism 7. Multiple storage chambers arranged in sequence are provided in the storage box 1. Multiple water hoses 2 are respectively installed in the multiple storage chambers. One end of the water hose 2 at the starting end is connected to the fire truck, and the other end of the water hose 2 at the starting end is connected to the middle interface of the three-way ball valve 6. Water is pumped into the three-way ball valve 6 along the water supply hose 5 through the water supply mechanism, and the water will be transported to the water supply tank of the fire truck along the water hose 2, wherein one end of the water supply hose 5 is connected to the water supply mechanism, and the other end of the water supply hose 5 is installed on the quick-change mechanism 4. The quick-change mechanism 4 is fixedly installed on the crawler walking mechanism 7, and the quick-change mechanism 4 is used to connect the other end of the water supply hose 5 to the bottom of the three-way ball valve 6 A connecting hose 3 is provided between each two water hoses 2. One end of the connecting hose 3 contacts and connects with the top of the three-way ball valve 6, and the other end of the connecting hose 3 connects to the top interface of the water hose 2. A slide 1a is provided on the outside of the storage tank 1 for the three-way ball valve 6 to slide horizontally into the storage tank 1. The slide 1a allows the three-way ball valve 6 to be installed on the outside of the storage tank 1, facilitating the quick-change mechanism 4 to connect the water supply hose 5 with the three-way ball valve 6 and to facilitate the removal of the connecting hose 3 from the three-way ball valve 6. A valve switching mechanism 8 is fixedly mounted on the quick-change mechanism 4. The valve switching mechanism 8 is used to rotate and switch the valve core in the three-way ball valve 6. The spherical valve core in the three-way ball valve 6 has only one passage. Before the three-way ball valve 6 is driven to rotate by the valve switching mechanism 8, this passage connects the connecting hose 3 and the water hose 2. After the rotation is switched, the passage connects the water supply hose 5 and the water hose 2.

[0029] It should be noted that the ends of the hose 2, connecting hose 3, and water supply hose 5 are all equipped with metal clamps, which are all of the specifications used in fire protection equipment. The clamps on the ends of the hose 2, connecting hose 3, and water supply hose 5 are all clamps of metal clamps.

[0030] When the water-taking robot is walking, Figure 2As shown, the quick-change mechanism 4 does not contact the water supply hose 5 and the three-way ball valve 6, and the valve switching mechanism 8 does not drive the valve core in the three-way ball valve 6 to rotate and switch. This allows the water hose 2 on the ground to continuously pull the water hose 2 on the robot down through the friction with the ground. When a row of water hoses 2 is used up, it will pull the three-way ball valve 6 along the slide 1a, causing the three-way ball valve 6 to be pulled into the storage box 1 and then pulled out to the ground along the inside of the storage box 1. It is then connected to the next water hose 2 through the connecting hose 3, and the next water hose 2 is pulled out.

[0031] When the water-collecting robot is about to finish walking or has finished walking, Figure 3 As shown, the quick-change mechanism 4 connects the water supply hose 5 to the three-way ball valve 6, and the valve switching mechanism 8 drives the valve core in the three-way ball valve 6 to rotate and switch, so that the water pumped out by the water supply mechanism can enter the water hose 2 along the water supply hose 5 and the three-way ball valve 6, and be transported to the water supply tank in the fire truck along the water hose 2. According to the remaining path that the water-collecting robot needs to travel, the three-way ball valve 6 and the water supply hose 5 can be connected in advance through the quick-change mechanism 4. Among them, if the current drainage hose 2 is not used up, the water-collecting robot can take a detour to walk a certain distance to completely drain the drainage hose 2, and the detour distance of the water-collecting robot is short, and there will not be many bends.

[0032] like Figure 3 and Figure 4As shown, in order to enable the quick change mechanism 4 to connect the water supply hose 5 with the three-way ball valve 6 at any position, the quick change mechanism 4 includes a rotating mechanism 4a, a valve body clamp 4b, a lower clamp 4c, a longitudinal displacement mechanism 4d, a transverse displacement mechanism 4e, a lifting mechanism 4f, and a clamping seat 4h. The longitudinal displacement mechanism 4d is fixedly installed on the top of the track walking mechanism 7, the transverse displacement mechanism 4e is fixedly installed on the displacement seat of the longitudinal displacement mechanism 4d, the valve body clamp 4b is fixedly installed on the displacement seat of the transverse displacement mechanism 4e, the valve body clamp 4b is used to clamp the three-way ball valve 6 so that the three-way ball valve 6 cannot rotate, the rotating mechanism 4a is fixedly installed on the displacement seat of the transverse displacement mechanism 4e, the rotating mechanism 4a is used to drive the lifting mechanism 4f to rotate, the lifting mechanism 4f is fixedly installed on the rotating seat of the rotating mechanism 4a, the lifting mechanism 4f is used to push the lower clamp 4c downward, the lower clamp 4c is fixedly installed on the lifting mechanism 4f, and the lower clamp 4c is used to clamp one end of the water supply hose 5. The clamping seat 4h is fixedly installed on the position seat of the longitudinal displacement mechanism 4d, and one end of the water supply hose 5 can be clamped in the clamping seat 4h. When it is needed to connect the water supply hose 5 with the three-way ball valve 6, first, the lower clamp 4c is moved to the side of the three-way ball valve 6 at the specified position through the longitudinal displacement mechanism 4d, then the lower clamp 4c is horizontally pushed close to the end of the water supply hose 5 through the transverse displacement mechanism 4e and the lifting mechanism 4f, then the end of the water supply hose 5 is clamped through the lower clamp 4c, then the end of the water supply hose 5 is lifted upward through the lifting mechanism 4f so as to be inserted and matched with the three-way ball valve 6, and finally the lower clamp 4c is rotated through the rotating mechanism 4a, so as to realize the locking between the water supply hose 5 and the three-way ball valve 6.

[0033] The lifting mechanism 4f is needed to lift the lower clamp 4c upward and downward, mainly because the buckle is provided on the water supply hose 5, and the top of the buckle protrudes from the top surface of the water supply hose 5.

[0034] As Figure 5 and Figure 6As shown, in order to enable the valve switching mechanism 8 to rotate switch the three-way ball valve 6, the valve switching mechanism 8 includes a rotary motor 8a and a clamping pipe 8b, the rotary motor 8a is fixedly connected with the valve body clamp 4b through a connecting frame, the clamping pipe 8b is rotatably installed on the connecting frame, wherein the connecting frame is connected with the horizontal displacement mechanism 4e and the slide, the valve body clamp 4b is fixedly connected with the connecting frame, the output end of the rotary motor 8a is in transmission connection with the clamping pipe 8b through a gear set, the spherical valve core of the three-way ball valve 6 is fixedly provided with a rotating shaft 6a for driving it to rotate, a clamping groove is formed on the outer edge of the rotating shaft 6a, and the clamping pipe 8b is fixedly provided with a clamping strip matched with the clamping groove. The rotary motor 8a is driven by the horizontal displacement mechanism 4e to move horizontally, so that the clamping pipe 8b is sleeved on the outer edge of the rotating shaft 6a, that is, the clamping pipe 8b and the rotating shaft 6a are clamped, then the rotary motor 8a is controlled to work, so that the rotary motor 8a drives the clamping pipe 8b to rotate, that is, the rotating shaft 6a drives the spherical valve core to rotate and switch. The rotation range of the spherical valve core of the three-way ball valve 6 is 180 degrees.

[0035] As shown in Figure 4 and Figure 7 shown, in order to lock the water supply hose 5 with the three-way ball valve 6 when the water supply hose 5 is inserted into the three-way ball valve 6, the rotating mechanism 4a includes a support frame 4a1, a rotating frame 4a2 and an electric push rod 4a3, the support frame 4a1 is fixedly installed on the displacement seat of the horizontal displacement mechanism 4e, the rotating frame 4a2 is rotatably installed on the support frame 4a1, the tail of the electric push rod 4a3 is rotatably installed on the support frame 4a1, the output end of the electric push rod 4a3 is hinged with the rotating frame 4a2, and the rotating axis of the rotating frame 4a2 is coaxially arranged with the top interface of the three-way ball valve 6, so that the water supply hose 5 can be rotatably locked with the end of the three-way ball valve 6. The rotating frame 4a2 is rotated around the hinge with the support frame 4a1 by controlling the electric push rod 4a3 to push, so that the rotating frame 4a2 can be rotated by 90 degrees, and the clamping between the water supply hose 5 and the three-way ball valve 6 can be achieved by 90 degrees of rotation.

[0036] As shown in Figure 4 shown, in order to more stably clamp the three-way ball valve 6, the valve body clamp 4b is two, both of which are fixedly installed on the displacement seat of the horizontal displacement mechanism 4e, and are used to clamp the upper and lower ends of the three-way ball valve 6 respectively. The three-way ball valve 6 is clamped by the two valve body clamps 4b, so that the three-way ball valve 6 is more stable, the top of the top valve body clamp 4b is provided with an upper clamp 4j, the upper clamp 4j is fixedly installed on the rotating mechanism 4a, and the upper clamp 4j is used to clamp the connecting hose 3 installed on the top of the three-way ball valve 6. The connecting hose 3 is clamped by the upper clamp 4j, and then the upper clamp 4j is rotated by the rotating frame 4a2, so as to realize the disassembly of the connecting hose 3.

[0037] As shown in Figure 8 andFigure 9 As shown, the storage box 1 includes a baffle 1d, a box body 1e, a plurality of lifting blocking mechanisms 1b and a plurality of rotating baffles 1c, the box body 1e is fixedly installed on the top of the crawler traveling mechanism 7, a plurality of partitions are fixedly arranged in the box body 1e, the plurality of partitions are used to divide the internal space of the box body 1e, a plurality of water hose avoiding notches are formed on the side of the box body 1e close to the tail of the robot, the lifting blocking mechanism 1b covers the water hose avoiding notches, when the water hose 2 needs to be discharged, the baffle is retracted downward through the lifting blocking mechanism 1b, thereby not blocking the water hose avoiding notches, so that the water hose 2 can be easily discharged when the vehicle is running, wherein the partitions and the side of the box body 1e in contact with the water hose 2 have extrusion friction, so that the robot will not shake the water hose 2 and fall a large amount of water hose 2 to the ground when running. The side of the box body 1e close to the head of the robot is provided with a valve body avoiding notch for the three-way ball valve 6 to pass through, the rotating baffle 1c covers the valve body avoiding notch, and the bottom of the rotating baffle 1c is rotatably connected with the box body 1e, the baffle 1d is fixedly installed on the outside of the box body 1e, the side of the box body 1e is in contact with the baffle 1d, and the other side of the rotating baffle 1c is in contact with the water hose 2, the rotating baffle 1c is used to block the water hose 2, so that the water hose 2 is prevented from falling due to the valve body avoiding notch when being stacked, and after the water hose 2 is completely pulled out, the rotating baffle 1c can be rotated towards the side of the water hose 2.

[0038] As shown in the figure, Figure 10 The slide 1a is a U-shaped structure, and the slide 1a is two, the upper and lower ends of the three-way ball valve 6 are respectively clamped in the two slides 1a, and the slide 1a is provided with an elastic pressing mechanism 1f for blocking the three-way ball valve 6. The slide 1a lifts and limits the three-way ball valve 6, and then the elastic pressing mechanism 1f extrudes and positions the three-way ball valve 6, so as to avoid vibration displacement of the three-way ball valve 6 when the robot is running. The elastic pressing mechanism 1f and the three-way ball valve 6 have extrusion friction. And the three-way ball valve 6 also does not have a large rotating displacement on the slide 1a, because the water hose 2 is connected with the three-way ball valve 6.

[0039] As shown in the figure, Figure 10 The elastic pressing mechanism 1f includes a rotating rod 1f1 and a torsional spring 1f2, the rotating rod 1f1 is rotatably installed on the slide 1a, and the torsional spring 1f2 is used to apply an elastic force to the rotating rod 1f1 to resist the three-way ball valve 6. When the water hose 2 pulls the three-way ball valve 6, the three-way ball valve 6 can push the rotating rod 1f1 to rotate, so that the three-way ball valve 6 slides out along the slide 1a.

[0040] In use, the water hose 2 in the storage box 1 can be automatically discharged from the storage box 1 by walking displacement through the track walking mechanism 7, and when the water hose 2 is discharged, the connection of the water hose 3 can be connected, and the next row of water hose 2 is automatically discharged by pulling, and before the next row of water hose 2 is discharged, the blocking mechanism 1b needs to be lifted to retract the baffle. When the water taking robot walking is about to end or has ended, the water supply hose 5 is connected with the three-way ball valve 6 through the quick change mechanism 4, and the ball valve in the three-way ball valve 6 is switched through the valve switching mechanism 8, that is, installation is realized. The subsequent work can be carried out by the water pumping mechanism to pump the lake water into the water supply tank of the fire truck.

[0041] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
