[0033] As Figure 1 shown, this embodiment discloses a docking device, including a moving mechanism 10, a guide rod 20, a spring pressing rod 30, a first elastic member 40, a hanging bracket 50, a second elastic member 60, a fire hose 70, a docking mechanism 80, a third telescopic member 90, an insulating member 100, and a mains plug 110, specifically as follows:

[0034] AsFigure 2 As shown, the moving mechanism 10 is used to drive each component to move in the first horizontal direction, where the first horizontal direction is configured as the horizontal transverse direction. In this embodiment, the moving mechanism 10 includes a guide rail 11 and a moving frame 12. The guide rail 11 can be arranged on an external fire truck or other structures, and the length direction of the guide rail 11 is configured as the first horizontal direction; the lower end of the moving frame 12 is slidably arranged on the guide rail 11, and the moving frame 12 can slide along the first horizontal direction on the guide rail 11. In addition, the moving mechanism 10 of this embodiment can also adopt an existing linearly movable structure.

[0035] As Figure 2 shown, there are at least two guide rods 20. In this embodiment, two guide rods 20 are schematically arranged in parallel along the first horizontal direction. The guide rods 20 are slidably penetrated through the moving frame 12 in the height direction, and the guide rods 20 can slide up and down relative to the moving frame 12. In this embodiment, the guide rod 20 is axially divided into a first section 21, a second section 22, and a third section 23 that are sequentially connected. The first section 21 is slidably penetrated through the moving frame 12, and the lower end of the first section 21 is universally connected to the upper end of the second section 22 through a universal joint, and the lower end of the second section 22 is universally connected to the third section 23 through a universal joint. Designing the guide rod 20 as a multi-section with movable connections in this embodiment can make the hanging frame 50 connected to the third section 23 of the guide rod 20 have a certain degree of flexibility, avoiding being too rigid when the fire hose 70 is docked and causing docking difficulties.

[0036] As Figure 2 shown, the spring pressure rod 30 is horizontally arranged, and both ends of the spring pressure rod 30 are respectively connected to the upper ends of the two guide rods 20, specifically, the upper ends of the first sections 21 of the guide rods 20. The function of the spring pressure rod 30 is to connect the two guide rods 20 into one body, and at the same time, it can facilitate providing a limiting point for the first elastic member 40.

[0037] As Figure 2 shown, the first elastic member 40 is configured as a spring. The first elastic members 40 are arranged in one-to-one correspondence with the guide rods 20, and the first elastic members 40 are coaxially sleeved on the first sections 21 of the guide rods 20. The upper end of the first elastic member 40 abuts against the spring pressure rod 30, and the lower end of the first elastic member 40 abuts against the upper surface of the moving frame 12. The telescopic direction of the first elastic member 40 is configured as the height direction. Designing the first elastic member 40 in this embodiment can make the hanging frame 50 have a certain elastic floating ability, and the hanging frame 50 can move with only a very small force, which can compensate for a certain docking deviation.

[0038] As Figure 1 shown, the hanging frame 50 is welded by multiple plate structures, and can provide installation positions for components such as the docking mechanism 80 and the mains plug 110. The upper end of the hanging frame 50 is threadedly connected to the third section 23 of the guide rod 20.

[0039] As Figure 1 and Figure 2 shown, the second elastic member 60 is configured as a spring, and the second elastic member 60 is connected between the hanger 50 and the moving frame 12. Specifically: a first connecting rod 51 is provided on the hanger 50, and a second connecting rod 52 is provided on the moving frame 12. The first connecting rod 51 and the second connecting rod 52 are coaxially and correspondingly arranged in the first horizontal direction. One end of the second elastic member 60 is coaxially sleeved on the first connecting rod 51, and the other end of the second elastic member 60 is coaxially sleeved on the second connecting rod 52, and the telescopic direction of the second elastic member 60 is configured as the first horizontal direction. In this embodiment, designing the second elastic member 60 enables the hanger 50 to have a certain amplitude of elastic swing to make up for a certain docking deviation. Among them, the first elastic member 40 and the second elastic member 60 in this embodiment can enable the hanger 50 to have a certain activity amplitude in multiple directions, which is convenient for making up for the docking precision error and realizing flexible docking.

[0040] As Figure 1 shown, the fire hose 70 is arranged on the docking mechanism 80, and the fire hose is horizontally docked to the external docking pile 120 (the docking pile 120 can be regarded as a water source) through the docking mechanism 80, and thus fire fighting operations can be realized.

[0041] As Figures 3 to 5 shown, the docking mechanism 80 includes a fixed sleeve 81, a first telescopic member 82, a translational chuck assembly 83 and a second telescopic member 84; both the fixed sleeve 81 and the fire hose 70 are circular. The fixed sleeve 81 is horizontally fixed at the lower end of the hanger 50, and the axial direction of the fixed sleeve 81 is configured as the first horizontal direction; the fire hose 70 is coaxially and slidably arranged in the fixed sleeve 81, and there is a clearance fit between the fire hose 70 and the fixed sleeve 81; both ends of the first telescopic member 82 (such as an electric push rod, etc.) are hinged to the fixed sleeve 81 and the fire hose 70 respectively, and the telescopic direction of the first telescopic member 82 is configured as the first horizontal direction. By telescoping the first telescopic member 82, the fire hose 70 can be driven to approach and move away from the docking pile 120; the number of the first telescopic members 82 can be multiple, and the multiple first telescopic members 82 are equidistantly arranged along the circumferential direction of the fixed sleeve 81; the translational chuck assembly 83 is coaxially arranged on the fixed sleeve 81, and the translational chuck assembly 83 can clamp on the docking pile 120, so as to realize the positioning with the docking pile 120, which is convenient for the fire hose 70 to be accurately docked to the docking pile 120; both ends of the second telescopic member 84 (such as an electric push rod) are hinged to the translational chuck assembly 83 and the fixed sleeve 81 respectively. By telescoping the second telescopic member 84, the translational chuck assembly 83 is driven to clamp on the external docking pile 120 or to drive the translational chuck assembly 83 to release the docking pile 120; the number of the second telescopic members 84 can be multiple, and the multiple second telescopic members 84 are equidistantly arranged along the circumferential direction of the fixed sleeve 81.

[0042] As shown in Figure 6 and Figure 7 FIG. 5, the translational chuck assembly 83 includes a chuck base 831 (circular), a sliding sleeve 832, and a plurality of chuck groups 833; the chuck base 831 is coaxially and fixedly connected to the end of the fixed sleeve 81, and is used to provide an installation position for the plurality of chuck groups 833; the sliding sleeve 832 is coaxially sleeved on the fixed sleeve 81, and the sliding sleeve 832 is located on the side of the chuck base 831 away from the docking pile 120. Wherein, both ends of the second telescopic member 84 are respectively hinged to the sliding sleeve 832 and the fixed sleeve 81, and the sliding sleeve 832 can be driven to slide on the outer periphery of the fixed sleeve 81 through the second telescopic member 84; the number of the chuck groups 833 is six, and the six chuck groups 833 are arranged on the chuck base 831 at equal intervals along the circumferential direction of the chuck base 831. By pushing the sliding sleeve 832 to move through the second telescopic member 84, the sliding sleeve 832 drives the chuck group 833 to clamp or release the docking pile 120.

[0043] As shown in Figure 6 FIG. 6, the chuck group 833 includes a chuck seat 8331, a chuck 8332, a first link 8333, a second link 8334, and a linkage rod 8335; the chuck seat 8331 is detachably arranged on the chuck base 831; a slot cooperating with the chuck 8332 is arranged on the docking pile 120, and the chuck 8332 can be inserted into the slot to realize positioning with the docking pile 120; the first link 8333 is linear, one end of the first link 8333 is hinged to the chuck 8332, and the other end of the first link 8333 is hinged to the chuck seat 8331; the second link 8334 is L-shaped, one end of the second link 8334 is hinged to the chuck 8332, and the middle position of the second link 8334 is hinged to the chuck seat 8331. The first link 8333 and the second link 8334 are arranged in parallel, and a four-bar mechanism is formed among the chuck 8332, the first link 8333, the second link 8334, and the chuck seat 8331; wherein, at least a part of the structure of the second link 8334 extends away from the chuck base 831, and the extended structure is hinged to one end of the linkage rod 8335, and the other end of the linkage rod 8335 is hinged to the sliding sleeve 832.

[0044] As shown in Figure 1 and Figure 6As shown, the working principle of the chuck group 833 is as follows: when the second telescopic member 84 drives the sliding sleeve 832 to slide towards the docking pile 120, the linkage rod 8335 pushes the second connecting rod 8334 to move, and the second connecting rod 8334 pushes the chuck 8332 to move, thereby realizing that each chuck 8332 clamps towards the axis of the fixed sleeve 81 (i.e., converges centripetally). The slots on the docking pile 120 are inserted and matched with the chucks 8332 one by one. When the chucks 8332 converge centripetally, they can be inserted into the slots to achieve positioning; when the second telescopic member 84 drives the sliding sleeve 832 to slide away from the docking pile 120, each chuck 8332 withdraws from the slot and expands outward.

[0045] In some preferred solutions, such as Figure 7 As shown, the chuck base 831 is provided with a chute 831a along its radial direction. The chutes 831a are arranged corresponding to the chuck seats 8331 one by one, and a plurality of chutes 831a are evenly distributed along the circumferential direction of the chuck base 831 at equal intervals; the inner width of the chute 831a is equal to the width of the chuck seat 8331. At least part of the chuck seat 8331 is arranged in the chute 831a. The position of the chuck seat 8331 can be restricted to be adjusted only in the radial direction of the chuck base 831 through the chute 831a, so as to facilitate clamping and positioning with the docking piles 120 of different outer diameters. Among them, mounting holes 831b are arranged on the inner bottom surface of the chute 831a, and a plurality of mounting holes 831b are arranged at equal intervals along the radial direction of the chuck base 831 (the plurality of mounting holes can facilitate the chuck seat 8331 to select the mounting position). The bottom surface of the chuck seat 8331 is provided with threaded holes, and threaded members (such as bolts, etc., not marked) pass through the mounting holes 831b and are connected to the threaded holes of the chuck seat 8331, thereby realizing that the chuck seat 8331 can be stably on the chuck base 831. When the position of the chuck seat 8331 needs to be adjusted, only need to loosen the threaded member and slide the position of the chuck seat 8331, and then lock the chuck seat 8331 again through the threaded member.

[0046] In some preferred solutions, such as Figure 3 and Figure 6As shown, the translational chuck assembly 83 further includes a first proximity switch 834 and a second proximity switch 835. The first proximity switch 834 is disposed on the chuck 8332 for detecting the position of the chuck 8332 and the docking pile 120. The second proximity switch 835 is disposed on the fixed sleeve 81 for detecting the axial position between the fire hose 70 and the fixed sleeve 81. Each chuck 8332 is provided with a first proximity switch 834. When multiple chucks 8332 are folded down to the outer diameter size of the docking pile 120 and inserted into the slot, the first proximity switch 834 emits a signal indicating that the positioning with the docking pile 120 has been completed. At this time, the first telescopic member 82 drives the fire hose 70 to approach the docking pile 120. When the second proximity switch 835 detects that the distance between a certain position on the fire hose 70 and the fixed sleeve 81 reaches a preset value, the fire hose 70 just completes the docking with the docking pile 120. The second proximity switch 835 transmits this signal to the central control, and the central control can then control the docking pile 120 to open the water source to provide water for fire extinguishing.

[0047] As Figure 3 shown, the third telescopic member 90 is disposed on the hanger 50 and is located above the fixed sleeve 81. The telescopic direction of the third telescopic member 90 is configured as the first horizontal direction. The two ends of the insulating member 100 (such as made of rubber, sponge, etc.) are respectively connected to the telescopic end of the third telescopic member 90 and the mains plug 110. The mains plug 110 is located on this side of the hanger 50 close to the docking pile 120. The distance between the mains plug 110 and the fire hose 70 is equal to the distance between the docking pile 120 and the mains socket 130. Since the relative positions of the mains plug 110 and the fire hose 70 are fixed, only by positioning the relative distance between the mains plug 110 and the fire hose 70 according to the relative distance between the docking pile 120 and the mains socket 130, the automatic docking of the fire hose 70 with the docking pile 120 can be completed while the automatic insertion of the mains plug 110 into the mains socket 130 is achieved. In addition, in this embodiment, an insulating member 100 is provided between the third telescopic member 90 and the mains plug 110, which can improve safety. Moreover, the flexible insulating member 100 can deflect within a certain range under the action of an external force, and can compensate for the error generated during the docking of the mains plug 110 and the mains socket 130 within a certain range.

[0048] One working mode of the docking device in this embodiment is as follows:

[0049] During operation, after the fire truck stops at the designated position, the moving frame 12 moves to a position close to the docking pile 120 and the mains socket 130. The second telescopic member 84 of the docking mechanism 80 extends, thereby pushing the sliding sleeve 832 to slide, causing the plurality of chucks 8332 to open. After the moving frame 12 moves forward a short distance to the designated position again, the second telescopic member 84 retracts, driving the plurality of chucks 8332 to converge centripetally. Each chuck 8332 is provided with a first proximity switch 834. When the chucks 8332 converge to the outer diameter size of the docking pile 120, the chucks 8332 will be clamped in the slots on the docking pile 120. At the same time, the first proximity switch 834 on the chuck 8332 will send a signal indicating that the positioning with the docking pile 120 has been completed. Then, the first telescopic member 82 retracts, driving the fire hose 70 to move to the left, thereby pushing the buckle joint of the fire hose 70 to be fastened to the buckle joint on the docking pile 120. During the process of the buckle joint of the fire hose 70 being fastened to the buckle joint on the docking pile 120, the second proximity switch 835 will approach a certain position on the fire hose 70. When the second proximity switch 835 senses that the distance to this position reaches the preset value, it indicates that the fire hose 70 and the docking pile 120 have been docked. The second proximity switch 835 sends the docking completed signal to the central control, and the central control can then control the docking pile 120 to discharge water to provide a water source for fire extinguishing;

[0050] Among them, during the docking process of the fire hose 70 and the docking pile 120, the third telescopic member 90 drives the mains plug 110 to be inserted into the mains socket 130, so that while the joint of the fire hose 70 and the docking pile 120 is automatically docked, the mains plug 110 and the mains socket 130 are synchronously docked.

[0051] As described above, only the specific embodiments of the present application are provided. Those skilled in the art can clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules, and units described above can refer to the corresponding processes in the foregoing method embodiments and will not be repeated here. It should be understood that the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application.
