DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-6 , a smart fire-fighting robot with an emergency obstacle avoidance function, comprising a fire-fighting robot body 1, a mounting member 11 is fixedly arranged on the top of the fire-fighting robot body 1, a protective plate 2 is movably arranged in front of the fire-fighting robot body 1, and a laser radar sensor 21 is fixedly arranged on the top of the protective plate 2. A lower water tank 4 is fixedly arranged in front of the fire-fighting robot body 1, a liquid capsule 41 is fixedly arranged on the lower water tank 4, the other end of the liquid capsule 41 is fixedly connected to the back of the protective plate 2, and an upper water tank 31 for supplying water to the lower water tank 4 is fixedly arranged on the top of the fire-fighting robot body 1.

[0019] Among them, the top of the fire-fighting robot body 1 is fixedly provided with an upper fixing seat 3, and the top of the upper fixing seat 3 is fixedly provided with an upper water tank 31. Through the setting of the upper water tank 31, the lower water tank 4 and the liquid capsule 41 can be supplied with water.

[0020] An upper pump assembly 32 is fixedly arranged on the top of the upper water tank 31, an input end of the upper pump assembly 32 is connected to the upper water tank 31, an output end of the upper pump assembly 32 is connected to an upper pump pipe 33, and the other end of the upper pump pipe 33 is connected to the lower water tank 4. By setting the upper pump assembly 32, water in the upper water tank 31 can be introduced into the lower water tank 4.

[0021] A lower pump assembly 42 is fixedly arranged on the top of the lower water tank 4, the input end of the lower pump assembly 42 is connected to the lower water tank 4, the output end of the lower pump assembly 42 is connected to the lower pump pipe 43, and the other end of the lower pump pipe 43 is connected to the upper water tank 31. Through the arrangement of the lower pump assembly 42, the water in the lower water tank 4 can be poured into the upper water tank 31.

[0022] Therein, movable columns 22 are fixedly and vertically arranged on both sides of the rear of the protection plate 2 , and a plurality of guide rods 23 are fixedly arranged on the outer sides of the movable columns 22 on the protection plate 2 .

[0023] Among them, fixed columns 5 are fixedly arranged vertically on both sides of the front of the fire-fighting robot body 1, and spring cavities 51 are opened inward at the ends of the fixed columns 5, and springs 52 are installed outward on the inner wall of the spring cavities 51. The other ends of the springs 52 are fixedly connected to the movable columns 22, and the diameter of the movable columns 22 is the same as the diameter of the spring cavities 51. Through the arrangement of the springs 52, when the protective plate 2 is hit, the elastic force of the springs 52 can be used to buffer, so as to reduce the degree of impact on the fire-fighting robot body 1.

[0024] Among them, a plurality of guide members 53 are fixedly arranged on the inner wall of the spring cavity 51, and the corresponding guide members 53 on the movable column 22 are adapted to open guide grooves 221, and the ends of the guide cavity 221 are closed. Through the adaptation between the guide members 53 and the guide grooves 221, the movable column 22 can be guided, and because the ends of the guide grooves 221 are in a closed state, the movable column 22 will not fall off from the spring cavity 51.

[0025] Among them, the fire fighting robot body 1 is adapted to open a guide cavity 6 corresponding to the guide rod 23, and the length of the guide cavity 6 is greater than the length of the guide rod 23. Through the adaptation setting between the guide cavity 6 and the guide rod 23, the protective plate 2 can be further guided to improve the stability of the protective plate 2 during use.

[0026] In this embodiment, a mounting part 11 is provided on the fire robot body 1, and the user installs various fire-fighting facilities on the mounting part 11, such as a water spray gun, etc. A laser radar sensor 21 is provided on the top of the protective plate 2. Through the setting of the laser radar sensor 21, objects around the fire robot body 1 can be measured. And it is loaded into the AI ​​algorithm inside the fire robot body 1 to realize the automatic obstacle avoidance function of the fire robot body 1. It is worth noting that these are all prior arts and do not belong to the main technical problems to be solved in the present invention, so they will not be elaborated.

[0027] Furthermore, when the AI ​​algorithm in the fire-fighting robot body 1 predicts that the fire-fighting robot body 1 is about to collide with an obstacle, the water in the upper water tank 31 can be pumped into the lower water tank 4 through the upper pump body pipe 33 by the upper pump body assembly 32, and the liquid capsule 41 is bulged by the water continuously added to the lower water tank 4. In this way, when the protective plate 2 collides with an obstacle, the impact force generated by the collision can be buffered by the water-filled liquid capsule 41, thereby reducing the impact force of the fire-fighting robot body 1 due to the collision.

[0028] Furthermore, when the guard plate 2 is hit, the movable column 22 also moves synchronously into the spring cavity 51, thereby driving the guard plate 2 to move backward. At this time, the elastic buffering force applied by the spring 52 to the movable column 22 can further reduce the impact force on the fire fighting robot body 1.

[0029] Furthermore, the water in the lower water tank 4 is always filled, and by injecting the water in the upper water tank 31 into the lower water tank 4, the water in the lower water tank 4 can flow into the liquid capsule 41, so that the impact force generated by the collision can be buffered by the liquid capsule 41. The AI ​​algorithm in the fire-fighting robot body 1 predicts the extent to which the fire-fighting robot body 1 is about to collide with an obstacle. In this way, the filling capacity of the liquid capsule 41 can be controlled by predicting the collision degree, so as to achieve control of the collision buffer.

[0030] When the filling degree of the water flow in the liquid capsule 41 is required to be high, the water flow in the upper water tank 31 can be pumped into the lower water tank 4 through the upper pump body assembly 32. When the filling degree of the water flow in the liquid capsule 41 is required to be low, the water flow in the lower water tank 4 can be re-pumped into the upper water tank 31 through the lower pump body assembly 42. It is worth noting that the upper pump body assembly 32 and the lower pump body assembly 42 are automatically controlled by the AI ​​algorithm in the fire fighting robot body 1. And the AI ​​algorithm, the upper pump body assembly 32 and the lower pump body assembly 42 are all prior art, so they are not elaborated.

[0031] In the present invention, fire-fighting equipment is installed on the fire-fighting robot body 1 so that it can perform various fire-fighting tasks. Through the arrangement of the liquid bag 41 and the spring 52, the protective plate 2 can be doubly buffered, so that when the fire-fighting robot body 1 fails to avoid obstacles in time and collides, the fire-fighting robot body 1 can be buffered to avoid the fire-fighting robot body 1 from being limited in function due to a large impact force.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
