Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting robots, and in particular to a water hose connecting device for a fire-fighting robot in a converter station. Background Art

[0002] Converter stations are sites within a high-voltage direct current (HVDC) transmission system that convert AC to DC and vice versa, ensuring safety, stability, and power quality. As a crucial component of the power grid, converter stations facilitate inter-regional power transmission across the entire network. Their stable operation is crucial to social production. As high-voltage transmission voltage levels continue to increase, the number of converter station devices continues to grow, making fire safety a crucial concern.

[0003] Currently, firefighting robots in converter stations do not carry their own fire extinguishing agents due to size and structural limitations, as well as the need for long-term, continuous firefighting. Instead, they use fire hoses to deliver fire extinguishing agents. When a fire occurs, the fire hose must be unwound and laid simultaneously, and the laying process must prevent the hose from bending, which could affect water delivery efficiency. Furthermore, most fire cabinets only have one length of fire hose, and to ensure the maximum operating length, the hose is typically set to its maximum length. Regardless of the distance between the fire and the hose setting, the entire hose must be deployed. Consequently, even if a fire breaks out near the hose, the entire hose must be unwound and laid, which is time-consuming.

[0004] For example, the Chinese invention patent document with publication number CN115212499A discloses a fire inspection and fire extinguishing robot and its working method. Although the patent discloses that the rear of the robot carries a water hose assembly, which controls the release of the water hose connected to the fire monitor as soon as a fire is discovered, thereby facilitating a quick connection with the booster device, greatly shortening the preliminary preparation time for fire fighting, thereby enabling rapid water spraying to extinguish the fire in the initial stage of the fire, effectively ensuring the fire safety of the site, the patent still has the above-mentioned problems. Regardless of the distance between the fire location and the booster device, the fire hose needs to be fully laid out, resulting in that when a fire occurs near the booster device, all the fire hoses also need to be unwound and laid, and the preparation time before fire extinguishing is relatively long. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to shorten the preparation time before fire extinguishing.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

The fire cabinet contains at least two sets of fire hoses of different lengths. The fire cabinet is provided with a hose outlet port. The linear sliding module and the hose clamping and outlet module are arranged side by side inside the fire cabinet between the fire hose and the hose outlet port.

A rack engaged with the output end of the first drive component is fixed on the sliding joint holder. The output end of each group of fire hoses is clamped on the sliding joint holder.

[0010] By setting fire hoses of different lengths and automatically connecting them through a linear sliding module, fire hoses of different lengths can be selected to discharge water when a fire occurs, thereby preventing the unwinding and laying of fire hoses from taking too long, thereby shortening the preparation time before fire extinguishing. In addition, by setting a clamping module for discharging the hose, twisting and knotting of the fire hose can be prevented when the hose is discharged.

The driving roller is rotatably arranged on the fixed seat and connected to the output end of the second drive assembly. The driven roller is rotatably and vertically movable on the fixed seat above the driving roller and is connected to the output end of the third drive assembly. The second drive assembly is driven to drive the driving roller to rotate, and the third drive assembly is driven to drive the driven roller to move vertically on the fixed seat.

[0014] Preferably, the fixing seat is provided with two sets of parallel guide holes, and the driven roller is vertically movable and arranged between the two sets of guide holes.

[0015] Preferably, the second driving component is a second driving motor.

[0016] Preferably, the third drive assembly includes a third drive motor, a synchronous belt structure, a screw and a screw nut. The third drive motor is fixed on a fixed seat. The driving end of the third drive motor is connected to the synchronous belt structure. A rotatable screw is respectively provided on the fixed seats at both ends of the driven roller. Each set of screws is threadedly connected to the screw nut. Both ends of the driven roller pass through the fixed seat and are connected to the screw nut. Both driving ends of the synchronous belt structure are connected to the screw. Driving the third drive motor drives the synchronous belt structure to rotate to drive the screw to rotate, and then drives the screw nut to move vertically on the screw.

[0017] Preferably, a guide block is further provided on the fixing seat.

[0018] Preferably, the fire cabinet is further provided with a water inlet pipe, the water inlet pipe is provided with a branch pipe connected to the fire hose, and the branch pipe is provided with a solenoid valve.

[0019] Preferably, it further comprises a control system, which is arranged inside the fire cabinet and electrically connected to the linear sliding module and the clamping and outputting module.

[0022] 2. The hose connection device used by the converter station fire-fighting robot not only has a simple overall structure and easy operation and control, but also eliminates the need for manual unwinding of the fire hose, greatly reducing the risk of personnel directly participating in rescue work.

[0033] See Figures 1 to 2 This embodiment discloses a water hose connection device for a fire-fighting robot in a converter station, including a fire cabinet 1, a fire hose 2, a linear sliding module 3, a clamping and outputting module 4, and a control system 5.

[0034] The fire cabinet 1 is provided with at least two sets of fire hoses 2 of different lengths. In this embodiment, three sets are provided, namely a 30m fire hose, a 20m fire hose, and a 10m fire hose, which are discharged from top to bottom. The three different sizes of fire hoses 2 are used to adapt to different firefighting distances and prevent the fire hoses 2 from being bent due to excessive length during the firefighting process, which may affect the firefighting effect. The fire cabinet 1 is provided with a water inlet pipe connected to a water source. The water inlet pipe is provided with three branches, each of which is connected to a fire hose 2. Each branch is provided with a solenoid valve 6 for controlling the opening of the branch. The fire cabinet 1 has a hose outlet port. The linear sliding module 3 and the clamping and discharging module 4 are arranged side by side inside the fire cabinet 1 between the fire hose 2 and the hose outlet port. The control system 5 is provided inside the fire cabinet 1 and is electrically connected to the linear sliding module 3, the clamping and discharging module 4, the solenoid valve 6, and the firefighting robot 8. The control system 5 and the firefighting robot 8 can be connected by radio.

[0035] The output end of each group of fire hoses 2 is evenly arranged on the linear sliding module 4, and the fire hoses 2 can pass through the clamping belt output module 5 and the hose output hole in sequence to be connected to the fire robot 8.

[0036] Furthermore, a placement rack 7 is provided in the fire cabinet 1, and three groups of fire hoses 2 are horizontally stacked on the placement rack 7. Two groups of left and right baffles are provided on the placement rack 7 to prevent the fire hoses 2 from being distributed in a disorderly manner and getting tangled. At the same time, the baffles can also be opened to place the fire hoses 2. Two guide columns are also provided near the linear sliding module 3 to prevent the fire hoses 2 from being offset during the discharge process and affecting the discharge effect.

[0037] See Figure 3 The linear sliding module 3 includes a base 31, a guide rail 32, a first drive component 33, a sliding joint holder 34 and a rack 35. The base 31 is vertically fixed in the fire cabinet 1. The guide rail 32 and the first drive component 33 are vertically fixed on the base 31. A movable sliding joint holder 34 is provided on the guide rail 32. A rack 35 engaged with the output end of the first drive component 33 is fixed on the sliding joint holder 34. In this embodiment, the sliding joint holder 34 is provided with the same number of bayonet sockets 341 as the number of fire hoses 2. The output end female connector of each group of fire hoses 2 is correspondingly connected to the bayonet socket 341 of the sliding joint holder 34.

[0038] For details, see Figure 4 By driving the first driving component 33, the sliding joint holder 34 is driven to move vertically on the base 31, thereby driving each bayonet 341 on the sliding joint holder 34 to correspond to the water hose output hole, thereby automatically realizing different specifications of fire hoses 2 to adapt to different fire extinguishing distances, preventing the fire hose 2 from being too long and bending during the fire extinguishing process, affecting the fire extinguishing effect.

[0039] Furthermore, the first drive assembly 33 includes a first drive motor 331 and a drive gear 332. The first drive motor 331 is fixed on the base 31 and electrically connected to the control system 5. The output end of the first drive motor 331 is connected to the drive gear 332. The drive gear 332 is engaged with the rack 35. By driving the first drive motor 331, the drive gear 332 is driven to rotate, thereby driving the sliding joint holder 34 fixed with the rack 35 to move vertically on the guide rail 32.

[0040] See Figure 5 The belt clamping module 4 includes a fixed seat 41, a second drive component 42, a third drive component 43, a drive roller 44, and a driven roller 45. The fixed seat 41 is fixed inside the fire cabinet 1 between the fire hose 2 and the linear sliding module 3. The second drive component 42 and the third drive component 43 are fixed on the fixed seat 41. The drive roller 44 is rotatably arranged at the bottom of the fixed seat 41 and is connected to the output end of the second drive component 42. In this embodiment, the second drive component 42 is a second drive motor. The driven roller 45 is rotatably and vertically movable on the fixed seat 41 above the drive roller 44 and is connected to the output end of the third drive component 43. Specifically, two groups of parallel guide holes 411 are opened on the fixed seat 41, and the driven roller 45 is vertically movable between the two groups of guide holes 411.

[0041] The third driving assembly 43 includes a third driving motor 431, a synchronous belt structure 432, a screw rod 433, and a screw nut 434. The third driving motor 431 is fixed on the fixed seat 41. The driving end of the third driving motor 431 is connected to the synchronous belt structure 431 and can drive the synchronous belt structure 432 to rotate. A rotatable screw rod 433 is respectively provided on the fixed seat 41 at both ends of the driven roller 45. Each set of screw rods 433 is threadedly connected to the screw nut 434. The two ends of the driven roller 45 pass through the guide holes 411 to connect the screw nuts 434. The two driving ends of the synchronous belt structure 432 are both connected to the screw rod 433. Driving the third driving motor 431 drives the synchronous belt structure 432 to rotate, thereby driving the two sets of screw rods 433 to rotate to drive the screw nut 434 to move vertically on the screw rod 433, and then driving the driven roller 45 to move vertically on the fixed seat 41.

[0042] For details, see Figures 5 to 7Before the connecting male head of the fire-fighting robot 8 is connected to the fire hose 2, the driven roller 45 is arranged on the top of the fixing seat 41, and there is a large space between it and the driving roller 44, so as to ensure that the connecting male head of the fire-fighting robot 8 can pass through the fixing seat 41 and connect with the connecting female head of the fire hose 2. When the connecting male head of the fire-fighting robot 8 is connected to the connecting female head of the fire hose 2 and is pulled out from the fixing seat 41, the third driving motor 431 is driven to drive the synchronous belt structure 432 to rotate, and drive the two sets of screw rods 433 to rotate to drive the screw nut 434 to move vertically downward on the screw rod 433, thereby driving the driven roller 45 to move vertically downward on the fixing seat 41 until the driving roller 44 and the driven roller 45 clamp the fire hose 2, stop the drive of the third driving motor 431, and at the same time, the second driving motor rotates, so that the driving roller 44 rotates, which plays a conveying role for the fire hose 2. Conversely, when the fire hose 2 is recovered, the second driving motor rotates in the opposite direction. The driving roller 44 and the driven roller 45 clamp the fire hose 2 so as to effectively prevent the fire hose 2 from twisting and tangling when it is discharged.

[0043] Furthermore, guide blocks 46 are provided on both ends of the fixing seat 41 above the driving roller 44 to reduce the friction between the fire hose 2 and the edges of the fixing seat 41 during the discharge of the fire hose 2 .

[0044] Furthermore, a layer of polyurethane material is applied to the surfaces of the driving roller 44 and the driven roller 45 to increase wear resistance and friction.

[0045] The working principle of this embodiment is: when an emergency fire occurs on the outgoing line of the converter station, a suitable set of fire hoses 2 is selected according to the distance of the fire. Specifically, taking the selection of a 10m fire hose as an example, the control system 5 first controls the first drive component 33 to drive, driving the sliding joint holder 34 to move vertically upward on the base 31, and driving the bottommost bayonet 341 on the sliding joint holder 34 that is engaged with the female head of the 10m fire hose to move to the position of the hose output hole. At the same time, the fire-fighting robot 8 is controlled by the control system 5 to move to the hose output hole, and the connecting male head of the fire-fighting robot 8 is connected to the connecting female head of the fire hose 2. Then, the fire-fighting robot 8 is driven to move and the connecting female head of the 10m fire hose is pulled out from the fixing seat 41. Afterwards, the third drive motor 431 is driven to drive the synchronous belt structure 432 to rotate, and the two sets of screw rods 433 are driven to rotate to drive the screw nut 434 to move vertically downward on the screw rod 433, and then drive the driven roller 45 to move vertically downward on the fixed seat 41 until the driving roller 44 and the driven roller 45 clamp the fire hose 2, and stop the drive of the third drive motor 431. At the same time, the second drive motor rotates to rotate the driving roller 44, which plays a conveying role for the fire hose 2. Then, the fire-fighting robot 8 pulls the fire hose 2 to the operating position, and the control system 5 controls the solenoid valve 6 on the branch pipe connected to the 10m fire hose to open for drainage, and the fire-fighting robot completes the fire-fighting operation task.

[0046] In this embodiment, by setting fire hoses 2 of different lengths, and through the linear sliding module 3, automatic connection of fire hoses 2 of different lengths can be achieved, so that when a fire occurs, a fire hose 2 of a suitable length range can be selected to discharge water, thereby preventing the unwinding and laying of the fire hose 2 from being too long, thereby shortening the preparation time before fire extinguishing, and through the setting of the clamping module 4, twisting and knotting of the fire hose 2 can also be prevented when it is discharged.

[0047] In addition, the hose connection device used by the converter station fire-fighting robot not only has a simple overall structure and easy operation and control, but also does not require manual unwinding of the fire hose, greatly reducing the risk of personnel directly participating in rescue work.
