[0021] Combined with Figures 1 to 5 A water hose robot according to the present invention is described.

[0022] like Figures 1 to 5 The water hose robot shown includes a main body 1 of the water hose robot, a walking mechanism, a water hose reel 5, a water distribution pipe 14 and a limiting roller. The walking structure is a crawler walking mechanism 11. The water hose reel 5 includes a rotating body 51 and a driving device 6. The crawler walking mechanism 11 is arranged at the bottom of the main body 1. The crawler walking mechanism 11 can increase the obstacle crossing ability of the water hose robot, so that it can adapt to most construction work scenes for operation; the water hose reel 5 is installed on the main body 1, and the rotating body 51 of the water hose reel 5 is used to install the water hose joint 7, and the driving device 6 drives the rotating body 51 to rotate. In order to simplify the structure of the water hose robot, the crawler walking mechanism 11 and the driving device 6 are driven by the same energy, preferably electric energy, and when the water hose robot operates the water hose, the rotation speed of the water hose reel 5 is coordinated with the walking speed of the crawler walking mechanism 11 to avoid dragging the water hose on the ground during the winding and unwinding process, thereby preventing the water hose from being worn. By controlling its speed, it can avoid the water hose from sinking into the bottom of the main body 1 when winding it and causing an accident.

[0023] The water distribution pipe 14 is provided with a first water distribution port matched with the joint 7, and the water distribution pipe 14 cooperates with the first water distribution port to form a drain port; the limiting roller is fixed on the water distribution pipe 14, and the limiting roller is used to provide a limit for the water hose when winding.

[0024] The water distribution pipe 14 includes a main pipe 141 and a secondary pipe 142. The two sides of the main pipe 141 are the first water distribution ports. The secondary pipe 142 is provided with a valve. One side of the secondary pipe 142 is connected to the main pipe 141, and the other side is provided with a second water distribution port. The size of the second water distribution port is smaller than that of the first water distribution port. The main pipe 141 in the water distribution pipe 14 is provided with a first water distribution port on both sides. The water hose wound on the water hose reel 5 is connected through the first water distribution port. When drainage is required, the water hose can be connected to the first water distribution port after unwinding to use the water distribution pipe 14 as a drainage port for drainage. The main pipe 141 is also provided with a secondary pipe 142. Through the second water distribution port on the secondary pipe 142, the water distribution pipe 14 can be connected to water hoses of other sizes for drainage, such as a fire hose, to provide a water source for firefighting operations.

[0025] The water baffle (not shown) matches the first water diversion port, and the water baffle is installed on the first water diversion port and closes the corresponding first water diversion port; when the water baffle is installed on the first water diversion port, the drainage port is the second water diversion port; when the water baffle is not installed on the first water diversion port, the drainage port is the first water diversion port and / or the second water diversion port. The water baffle can close the first water diversion port on one side, so that the water diversion pipe 14 can have more functions.

[0026] The hose reel 5 further includes a limit plate 52, which is disposed on both sides of the rotating body 51. The rotating body 51 is connected to the driving device 6 through the limit plate 52. The limit plate 52 can assist the rotating body 51 in winding up the hose.

[0027] The driving device 6 includes a motor 61 and a gear transmission mechanism 62. The rotating body 51 includes a rotating shaft disposed through a side limit plate 52, and the rotating shaft is in transmission connection with a driven wheel 621 in the gear transmission mechanism 62. The gear transmission mechanism 62 has a higher reliability rate than other transmission mechanisms, and is convenient for adjusting the speed of the rotating body 51 to reel in the water hose in accordance with the output speed of the motor 61.

[0028] like Figure 1 and Figure 4 As shown, the limiting roller is fixed on the main body 1 and is arranged at the front end of the rotating body 51. The limiting roller includes a transverse limiting roller and a vertical limiting roller 2. The transverse limiting roller is pressed against the water hose when the water hose is rolled up so that it can discharge the retained water. The vertical limiting roller 2 prevents the water hose from deviating when it is rolled up.

[0029] The water distribution pipe 14 also includes a roller bracket 12, and the transverse limiting roller includes a fixed roller 3 and a detachable roller 4. The fixed roller 3 is fixed on the roller bracket 12. The roller bracket 12 is provided with a mounting position for the detachable roller 4 above the fixed roller 3. The mounting position has a limiting position to provide vertical limiting for the detachable roller 4, and also has a disassembly position to disassemble the detachable roller 4 from the mounting position. In order to cooperate with the working nature of the water hose that cannot be installed in the limiting roller during drainage operations, but needs to be installed in the limiting roller after the drainage operation, a detachable roller 4 is provided in the limiting roller, so that the water hose can be detachably installed in the limiting roller. And because the water hose also has another water hose joint, in order to prevent accidents caused by the other water hose joint not being fixed after the water hose is rolled up on the water hose robot, the upper surface of the roller bracket 12 is used as the mounting surface of the other water hose joint so that it can be fixed on the roller bracket 12.

[0030] The vertical limiting roller 2 is mounted on the roller bracket 12, and the position of the vertical limiting roller 2 corresponds to the position of the gap between the fixed roller 3 and the detachable roller 4. During the process of winding the water hose, the water hose is pressed tightly in the gap between the fixed roller 3 and the detachable roller 4, and the vertical limiting roller 2 is arranged on both sides of the gap to prevent the water hose from horizontally deviating.

[0031] This solution provides a specific implementation of a detachable roller 4. One side of the detachable roller 4 is provided with a plug-in shaft 41, and the other side is provided with a limit shaft 42. The installation position is provided with a plug-in hole 121 on one side for the plug-in shaft 41 to be plugged in, and a limit groove 122 on the other side for the installation of the limit shaft 42.

[0032] This solution provides a specific disassembly method for the detachable roller 4. The limit groove 122 includes a retreat groove for the limit shaft 42 to retreat, and the detachable roller 4 moves toward the retreat groove to disengage the plug shaft 41 from the plug hole 121. The above structure can facilitate the installation and removal of the detachable roller 4 from the installation position.

[0033] The limiting shaft 42 is also provided with a handle 43, and the limiting groove 122 is provided with a through groove 123 for the handle 43 to extend out of the limiting groove 122. The handle 43 can conveniently adjust the position of the detachable shaft installed in the installation position, so as to disassemble and install the detachable shaft.

[0034] There are multiple rotating bodies 51, and the vertical limiting rollers 2 and fixed rollers 3 are arranged in positions matching the number of the rotating bodies 51. As shown in the drawings, there are two rotating bodies 51, and since the detachable rollers 4 are detachably arranged, they can be replaced and used without being arranged in the same number as the rotating bodies 51, but two can also be arranged as needed.

[0035] like Figure 1 As shown, the main body 1 is provided with a baffle 13 in front of the crawler walking mechanism 11 on the side where the limit roller is provided. In order to prevent the water hose from being scratched by dragging on the ground when winding, the crawler walking structure and the water hose reel 5 need to be linked so that the robot can move forward while winding. The baffle 13 is used to prevent the water hose from sinking under the chassis 15 of the main body 1 when winding, so that the winding action is stuck or even causes the water hose robot to overturn. The upper surface of the baffle 13 is a water hose guide surface 131 when the water hose is wound, and the water hose guide surface 131 is an inclined plane or an inclined arc surface facing the water hose reel 5.

[0036] Preferably, a sensor is provided on the chassis 15 of the main body 1 or the baffle 13, and the sensor is used to detect whether the hose is sunk into the bottom of the hose robot. When the crawler is found to be sunk into the chassis 15, a warning signal is sent, or the winding work is stopped, or the robot can reverse in time when the crawler is reversed.

[0037] When the sensor is a through-beam sensor, such as a through-beam photoelectric sensor, it is preferably installed on the chassis 15. When a water hose sinks into the bottom surface of the water hose robot, the water hose blocks the photoelectric signal of the through-beam photoelectric sensor, causing it to generate a warning signal.

[0038] The sensor is a visual detection sensor (such as a TOF sensor) or a microwave radar sensor. This type of sensor can be installed on the baffle 13 and the chassis 15. When a water hose is trapped under the bottom surface of the water hose robot, it is sensed and generates a warning signal.

[0039] like Figure 5 As shown, it also includes a traction device, which is fixed on the main body 1 and arranged at the rear end of the hose reel 5. The traction device is a winch 9 and / or a traction buckle 8. Therefore, the traction device is used to help the hose robot get out of trouble.

[0040] It also includes a control circuit board, which includes a speed control module. The speed control module is used to control the speed and direction of the hose reel and the traveling mechanism.

[0041] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
