Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting robots, and in particular to a fire-fighting mechanical arm robot for a control room. Background Art

[0002] Firefighting robot is a kind of automated equipment specially used in fire scene, which aims to improve the efficiency of fire rescue and reduce the risk of manual operation. With the development of robot technology and the increasing demand for fire rescue, firefighting robot has gradually become an important part of the modern firefighting system. In the future, with the continuous development of artificial intelligence, deep learning and multi-sensor fusion technology, firefighting robot will play an increasingly important role in fire rescue and enhance the overall emergency rescue capability.

[0003] In the prior art, a Chinese patent document with a publication number of CN213971215U proposes that a firefighting robot arm for indoor firefighting operation has five degrees of freedom, can realize all-round motion control, can automatically open the cabinet door after determining the fire point of the cabinet, remove obstacles at the fire point, and extinguish the fire without dead angles, which greatly improves the firefighting operation capability of the indoor firefighting robot and improves the safety of the information room. However, consistent with the traditional method, the water inlet pipe and the spraying rod of the traditional firefighting mechanical arm cannot usually maintain a relatively suitable state when the mechanical arm rises or falls, which will cause the water flow to deviate and affect the accuracy and effect of the firefighting, especially when spraying at high altitude or at multiple angles. The risk of the water flow deviating from the target is higher, and the water flow and pressure are difficult to adjust at any time according to the firefighting needs during the firefighting process. The traditional firefighting mechanical arm is usually unable to respond quickly, resulting in poor water flow control effect, and the spray pressure and range of the water flow are difficult to be effectively adjusted according to the height and distance of the fire source.

[0019] Beneficial effects of the present invention:

[0020] 1. This type of fire-fighting mechanical arm robot for the control room is equipped with a lifting assembly, which can coordinate the movement when the forearm rises or falls. The double-head motor synchronously drives the adjusting wheel and the driving rod. When the forearm rises, the adjusting wheel drives the driving rod to slide in the driving groove, pushing the adjusting plate to rise as a whole, so that the lifting roller moves up synchronously and stably lifts the water inlet pipe, thereby ensuring that the water inlet pipe and the spraying rod are always aligned. In addition, the fine-tuning rod is constrained by the limiting plate and the limiting block when sliding in the positioning groove, ensuring that the lifting roller does not shake during the up and down movement. The rubber lifting roller further provides stable support to prevent the water inlet pipe from slipping due to insufficient friction. Regardless of the rise or fall of the forearm, the lifting assembly can steadily support the water inlet pipe so that its position and angle accurately match the requirements of the spraying rod, thereby ensuring the effective spraying of water and the fire extinguishing effect.

[0021] 2. The fire-fighting manipulator robot for the control room is provided with an adjustment component. The adjustment drum is rotated by manual or automatic control, so that the rotating drum and the rotating ring rotate synchronously, driving a number of connecting rods to gradually pull or loosen the opening and closing plates. The retraction or expansion of the opening and closing plates controls the size of the adjustment holes in the connecting disk, thereby accurately adjusting the flow and pressure of the water flow. When the opening and closing plates are close together, the adjustment holes are closed, and the water flow is reduced or stopped; when the opening and closing plates are far apart, the adjustment holes are opened, and the water flow increases. The setting of the limit groove and the limit column further ensures that the rotation angle of the rotating ring will not exceed the preset range, preventing damage to the connecting rod or the opening and closing plate due to excessive rotation. The existence of the limit device also provides a clear stroke reference for the movement of the opening and closing plate, so that each adjustment can achieve the set water flow, thereby avoiding uneven water flow caused by adjustment errors. The overall design simplifies the operation, improves the accuracy, stability and component durability of water flow regulation, improves the control effect of the water flow during the fire extinguishing process, and ensures effective and stable injection pressure and coverage.

[0037] Embodiment 1: Figures 1 to 10As shown, a fire-fighting manipulator-arm robot for a control room comprises a base 1, a rotating motor 2 is arranged inside the base 1, and the output end of the rotating motor 2 is arranged through the top surface of the base 1; a rotating seat 3, the rotating seat 3 is arranged on the top surface of the base 1 and is connected to the output end of the rotating motor 2, the rotating motor 2 is used to drive the rotating seat 3 to rotate horizontally, a first rotating seat 4 is arranged above the rotating seat 3, a driving motor is arranged inside the first rotating seat 4, a large arm 5 is rotatably installed on one side of the first rotating seat 4, one side of the large arm 5 is fixedly connected to the output end of the driving motor, and a double-headed motor is fixedly installed on the other side of the large arm 5. A second rotating seat 6 is fixedly provided at the output end on one side, a small arm 7 is fixedly installed on one side of the outer surface of the second rotating seat 6, a spraying rod 8 is provided on the side of the small arm 7 away from the base 1, a water inlet pipe 9 is provided at the bottom of one side of the spraying rod 8, and a water spray head 11 is provided on the other side; a lifting component, the lifting component is arranged on one side of the big arm 5, and the lifting component is used to lift the water inlet pipe 9; an adjusting component, the adjusting component is arranged inside the spraying rod 8, and the adjusting component is used to adjust the opening and closing size of the spraying rod 8, wherein a connecting buckle 10 is provided on the side of the spraying rod 8 close to the small arm 7 to be clamped with the spraying rod 8, and a handle 12 is also rotatably installed on one side of the spraying rod 8;

[0038] When the control room issues a fire extinguishing command, the rotating motor 2 drives the rotating seat 3 on the base 1 to rotate horizontally, so that the mechanical arm turns to the fire source position, and the driving motor drives the large arm 5 to rise to the specified angle. At the same time, the double-headed motor is started to rotate the small arm 7 to the optimal angle, and the spray rod 8 is aimed at the fire source. The lifting component supports the water inlet pipe 9 to ensure that the water inlet pipe 9 has a stable water supply. At this time, the opening and closing size is adjusted by the adjustment component in the spray rod 8 to control the strength of the water flow to achieve the effect of precise fire extinguishing, and the sprinkler head 11 starts to spray water to extinguish the fire.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the lifting assembly includes an extension block 21 fixedly mounted on one side of the big arm 5, a rotating shaft 23 is rotatably mounted on one side of the extension block 21, an adjusting plate 22 is sleeved on one side of the rotating shaft 23, a positioning groove 27 is provided on the other side of the adjusting plate 22, a fine-tuning rod 29 is slidably mounted inside the positioning groove 27, a limiting plate 28 is fixedly mounted on one side of the fine-tuning rod 29, a lifting roller 30 is provided on one side of the limiting plate 28, and the lifting roller 30 is used to lift the water inlet pipe 9, two limiting blocks are provided on the inner wall of one side of the opening of the positioning groove 27, which are used to limit the fine-tuning rod 29, an adjusting wheel 24 is fixedly connected to the other output end of the double-headed motor, a driving groove 25 is provided on one side of the adjusting plate 22, a driving rod 26 is provided on one side of the adjusting wheel 24, the driving rod 26 is slidably mounted inside the driving groove 25, and the lifting roller 30 is made of rubber;

[0040] When the robot arm starts the rising action of the forearm 7, the two output shafts of the double-headed motor rotate synchronously, driving the forearm 7 and the lifting assembly to coordinate actions. At this time, one end of the double-headed motor rotates synchronously through the adjusting wheel 24 fixed on the forearm 7, and the driving rod 26 on the adjusting wheel 24 slides along the driving groove 25 in the adjusting plate 22, pushing the adjusting plate 22 to rotate and rise as a whole. The rise of the adjusting plate 22 directly drives the lifting roller 30 installed thereon to move upward, thereby stably lifting the water inlet pipe 9 (as shown in the sequence of I to IV in the figure). As the forearm 7 continues to rise, the synchronous action of the adjusting wheel 24, the driving rod 26 and the adjusting plate 22 keeps the lifting roller 30 moving upward stably, ensuring that the water inlet pipe 9 maintains an appropriate The support position, at the same time, the fine-tuning rod 29 in the lifting assembly moves upward synchronously in the positioning groove 27, and the restraining effect of the limit plate 28 and the limit block ensures that the fine-tuning rod 29 is only slightly adjusted in the positioning groove 27 to avoid shaking. The advantage of this is that the height of the water inlet pipe 9 can be automatically adjusted according to the position of the small arm 7 to ensure that the water inlet pipe 9 and the spraying rod 8 are always aligned. When the small arm 7 descends, the double-headed motor drives synchronously in the opposite direction, and the lifting roller 30 moves downward accordingly to ensure that the water inlet pipe 9 descends smoothly with the small arm 7 (as shown in the figure, IV to I sequence), without slipping or offset. During the whole process, the lifting assembly automatically adapts to the height change of the small arm 7, so that the water inlet pipe 9 remains stable, ensuring the accurate spraying of water and the fire extinguishing effect.

[0041] like Figures 6 to 10 As shown, an adjusting rotary cylinder 13 is rotatably mounted on one side of the water spray head 11 close to the spray rod 8, and the adjusting assembly includes a connecting disk 14 fixedly mounted between the spray rod 8 and the adjusting rotary cylinder 13, an adjusting hole is opened in the middle of the connecting disk 14, a rotating cylinder 15 is rotatably mounted on one side of the connecting disk 14, the outer wall of the rotating cylinder 15 is fixedly connected to the inner wall of the adjusting rotary cylinder 13, a rotating ring 16 is arranged on the inner wall of the rotating cylinder 15 close to the connecting disk 14, and a plurality of opening and closing plates 17 are rotatably mounted on one side of the connecting disk 14 close to the rotating cylinder 15, wherein the adjusting hole is closed when the plurality of opening and closing plates 17 are close to each other, and the adjusting hole is opened when the plurality of opening and closing plates 17 are far away from each other, a plurality of connecting rods 18 having the same number as the opening and closing plates 17 are rotatably mounted on one side of the rotating ring 16 close to the connecting disk 14, and the other side of the plurality of connecting rods 18 is rotatably connected to one side of the opening and closing plates 17, the diameter of the connecting disk 14 is larger than the diameter of the rotating cylinder 15, and the diameter of the connecting disk 14 is consistent with the outer diameter of the adjusting rotary cylinder 13;

[0042] When the fire extinguishing operation starts, the adjusting rotating cylinder 13 in the adjusting assembly will be manually or automatically controlled to rotate, thereby driving the rotating cylinder 15 fixedly connected to its inner wall to rotate synchronously. The rotation of the rotating cylinder 15 will further transmit the action through the rotating ring 16 at its inner wall near the connecting disk 14, driving a number of connecting rods 18, one end of these connecting rods 18 is fixed to the rotating ring 16, and the other end is hinged to the corresponding opening and closing plates 17. When the rotating ring 16 rotates, the connecting rod 18 gradually pulls the opening and closing plates 17, prompting the opening and closing plates 17 to expand or close with the adjusting hole of the connecting disk 14 as the center. Under the pulling action of the connecting rod 18, the distance between the opening and closing plates 17 gradually changes. When the opening and closing plates 17 are gradually brought together, the adjusting hole is gradually closed, so that the water flow is reduced or stopped; on the contrary, when the opening and closing plates 17 are gradually moved away, the adjusting hole is opened, and the water flow is gradually increased. Due to the synchronous adjustment of the rotating ring 16, the opening and closing plates 17 can accurately adjust the flow rate and injection angle of the water flow to meet different fire extinguishing needs and ensure the stability and control accuracy of the water flow during the fire extinguishing process;

[0043] The outer circumference of the rotating ring 16 is provided with a plurality of travel limit grooves 19, and a side of the connecting plate 14 close to the rotating ring 16 is provided with a plurality of travel limit columns 20 adapted to the travel limit grooves 19.

[0044] The travel limit groove 19 cooperates with the travel limit column 20 to limit the rotation angle of the rotating ring 16, preventing the rotating ring 16 from exceeding the preset rotation range, thereby protecting the internal components and avoiding deformation or damage of the connecting rod 18 or the opening and closing plate 17 due to excessive rotation, thereby improving the service life of the adjustment component. The cooperation between the limit groove and the limit column provides a travel reference for the rotation of the rotating ring 16, so that the opening and closing plate 17 can reach the set position when adjusting the water flow, ensuring that the water flow is adjusted more accurately, avoiding uneven water flow or inflexible adjustment, thereby achieving an ideal fire extinguishing effect.

[0045] Embodiment 2: Figure 7 , Figure 8 As shown, the outer surface of the adjusting drum 13 is provided with a plurality of convex strips;

[0046] When the adjusting drum 13 is set to manual control, the operator rotates and adjusts it by holding the convex strip area on the outer surface of the adjusting drum 13. The convex strip provides additional friction to prevent hand slippage. During the rotation process, the adjusting drum 13 drives the rotating drum 15 and the rotating ring 16 to rotate synchronously, thereby driving the connecting rod 18 to pull the opening and closing plate 17. When the opening and closing plates 17 are closed together, the adjustment hole gradually shrinks and the water flow pressure is increased; when the opening and closing plates 17 are opened, the adjustment hole is enlarged and the water flow coverage range is widened. The operator adjusts the water flow state according to the fire extinguishing needs to ensure that the sprayed water flow reaches the required pressure and range to meet the fire extinguishing needs at different angles;

[0047] When the adjustment drum 13 is set to the electric control mode, the adjustment system automatically controls the water flow according to the action state of the upper arm 5 or the lower arm 7. When the lower arm 7 rises or is adjusted to a high angle, the electric control system automatically detects the current height and instructs the adjustment drum 13 to rotate, shrink the adjustment hole, and increase the spray pressure of the water flow to achieve impact fire extinguishing at a longer distance. When the lower arm 7 descends or is aimed at a downward angle, the system enlarges the adjustment hole and expands the spray coverage of the water flow to ensure that the water flow is evenly distributed to meet the wide-area fire extinguishing needs at low-angle positions. The entire process realizes real-time automatic adjustment, ensures the stability and adaptability of the water flow for fire extinguishing, and improves the accuracy and efficiency of fire extinguishing.
