Description

Technical Field

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

[0002] A converter station refers to a station in a high-voltage direct current transmission system that realizes the conversion of alternating current into direct current or direct current into alternating current, and meets the power system's requirements for safety, stability and power quality. As an important part of the power grid, the converter station undertakes cross-regional power transmission across the entire network. The stable operation of the converter station is of great significance to social production. With the continuous improvement of the voltage level of high-voltage transmission, the number of converter station equipment continues to increase, so fire safety is particularly important.

[0003] At present, due to size and structure limitations and the need for long-term continuous fire fighting, the fire-fighting robots in the converter station do not carry fire extinguishing agents themselves, but use fire hoses to transport them. When a fire occurs, it is necessary to lay the fire hose while unwinding it, and during the laying process, it is also necessary to prevent the fire hose from bending and affecting the water output efficiency; in addition, most fire cabinets are only equipped with one length of fire hose, and in order to ensure the operating length, the fire hose is generally set to the maximum length. Regardless of the distance between the fire location and the fire hose setting location, the fire hose needs to be fully laid out, resulting in the fire near the fire hose. The location also needs to unwind and lay all the fire hoses, which is time-consuming.

[0004] For example, a 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 robot carries a water hose reel assembly at the rear to control the release of the water hose connected to the fire monitor as soon as possible after discovering a fire, thereby facilitating a quick connection with a 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 the need to unwind and lay all the fire hoses when a fire occurs near the booster device, resulting in a long preparation time before fire extinguishing.

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

[0034] At least two groups of fire hoses 2 of different lengths are arranged in the fire cabinet 1. In this embodiment, three groups are arranged, namely 30m fire hose, 20m fire hose and 10m fire hose, and they are discharged from top to bottom. The three different specifications of fire hoses 2 are used to adapt to different fire extinguishing distances to prevent the fire hose 2 from being bent due to being too long during the fire extinguishing process, which affects the fire extinguishing effect. The fire cabinet 1 is provided with a water inlet pipe connected to the water source, and the water inlet pipe is provided with three branches, each of which is connected to the fire hose 2, and each branch is provided with a solenoid valve 6 for controlling the opening of the branch; the fire cabinet 1 is provided with a hose output hole, and the linear sliding module 3 and the clamping and outputting module 4 are arranged in parallel inside the fire cabinet 1 between the fire hose 2 and the hose output hole, and the control system 5 is arranged inside the fire cabinet 1 and electrically connected to the linear sliding module 3, the clamping and outputting module 4, the solenoid valve 6 and the fire robot 8, and the control system 5 and the fire 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 randomly distributed and tangled. 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 also 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 meshing 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 holes 341 as the number of fire hose groups 2, and the output end female head of each group of fire hoses 2 is correspondingly connected to the bayonet hole 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 to affect the fire extinguishing effect.

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

[0040] See also Figure 5 The belt clamping module 4 includes a fixed seat 41, a second drive component 42, a third drive component 43, a driving 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 driving 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 driving 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 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. Rotatable screws 433 are respectively arranged on the fixed seats 41 at both ends of the driven roller 45. The screw nut 434 is threadedly connected on each group of screws 433. The guide holes 411 pass through the two ends of the driven roller 45 to connect the screw nuts 434. Both driving ends of the synchronous belt structure 432 are connected to the screw 433. The third driving motor 431 is driven to drive the synchronous belt structure 432 to rotate, thereby driving the two groups of screws 433 to rotate to drive the screw nut 434 to move vertically on the screw 433, thereby 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 with 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 the driven roller 45 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 with 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 driving 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 that the fire hose 2 can be prevented 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 on the surface of the driving roller 44 and the driven roller 45 to increase wear resistance and friction.

[0045] The working principle of this embodiment is as follows: 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 control system 5 controls the fire-fighting robot 8 to move to the hose output hole, and connects the male head of the fire-fighting robot 8 to the female head of the fire hose 2, and then drives the fire-fighting robot 8 to move and pulls the female head of the 10m fire hose out of the fixing seat 41. Afterwards, the third driving 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 the driving of the third driving motor 431 is stopped. At the same time, the second driving motor rotates to make the driving roller 44 rotate, 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, fire hoses 2 of different lengths are set, and the linear sliding module 3 can realize automatic connection of fire hoses 2 of different lengths, so that when a fire occurs, a fire hose 2 of a suitable length range can be selected for water discharge, thereby preventing the time for unwinding and laying the fire hose 2 from being too long, thereby shortening the preparation time before fire extinguishing, and by setting the clamping output 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 danger of personnel directly participating in rescue work.
