Description

Technical Field

[0001] This utility model relates to the field of fire-fighting robot accessories technology, and in particular to an automatic dehydration belt device. Background Technology

[0002] Firefighting robots have become an indispensable key piece of equipment in modern fire rescue. With their excellent fire extinguishing efficiency, precise detection technology and flexible mobility, they can perform tasks that are difficult for humans to accomplish in high-risk environments such as extreme high temperatures, dense smoke and toxic substances. They can not only greatly improve the efficiency of rescue operations, but also significantly reduce the life safety risks faced by firefighters.

[0003] Existing firefighting robots, such as the patent application with patent number CN202211719511.X entitled "A Firefighting Robot," mainly include a drive chassis and a spraying mechanism mounted on the drive chassis. The spraying mechanism requires connection of a channel pipe to a fire hose during use to supply firefighting water.

[0004] Currently, fire hoses are typically connected to robot access pipes using fire-fighting quick-release couplings. While these couplings are easy to install, disassembly requires manual pressing of the coupling's retaining ring to release the hose. However, fire-fighting robots operate in high-temperature, hazardous environments, and manually releasing the hose poses certain safety risks. Therefore, it is necessary to provide an automatic hose release device that enables automatic hose detachment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic dehydration belt device. It utilizes a threaded rotating sleeve and a moving cylinder. The electrically driven rotating sleeve rotates, which moves the moving cylinder to activate the spring clip inside the water belt interface, thereby detaching the belt from the water belt interface and avoiding the safety issues associated with manual dehydration belts.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic dehydration belt device, comprising a male connector, a rotating sleeve, and a movable cylinder arranged sequentially from the inside out. The male connector is used to connect to the female connector of the water hose. The rotating sleeve is rotatably connected to the male connector and driven to rotate along the male connector by an electronically controlled drive component. The movable cylinder is slidably disposed along the through groove of the male connector, and the inner wall of the movable cylinder is threadedly connected to the outer wall of the rotating sleeve. The rotating sleeve rotates, causing the moving cylinder to move toward the female connector, which pushes the spring clip inside the female connector to unlock the female connector from the male connector.

[0007] Compared with the prior art, the present invention has the following beneficial effects: It is understandable that the structure of the female connector on the water hose is existing technology (as shown in patent applications CN202020075399.0, CN201820043708.9, etc.), which is that multiple spring clips are set inside the connector to achieve the snap-fit ​​with the male connector.

[0008] In existing technologies, the snap-fit ​​connectors that connect to the female connector of the hose require manual manipulation of the snap-fit ​​connector's clips to release the spring clip inside the female connector, thus separating the female connector from the snap-fit ​​connector. In this application, based on the same unlocking principle, the movement of the moving cylinder used to release the spring clip inside the female connector is electrically driven. The rotating sleeve rotates under electric drive (such as a hollow shaft brushless motor, or a motor-drive mechanism combination, etc.). Through a threaded connection, the moving cylinder can move towards the female connector, thereby releasing the spring clip inside the female connector. This unlocks the female and male connectors, enabling automatic hose dewatering without manual dewatering, thus improving safety.

[0009] Furthermore, it also includes a mounting housing, which comprises spaced-apart fixed plates and mounting plates, which are connected to each other or via connectors to form a mounting space. The mounting plate extends outward from the end of the male connector away from the female connector and connects with the male connector. The fixing plate is arranged around the male connector near the connection end between the male connector and the female connector. The fixing plate has a moving channel that is intermittently arranged with the male connector. The electrically controlled drive unit is located within the installation space to drive the rotating sleeve to rotate within the installation space. The moving cylinder is slidably positioned within the installation space and partially reciprocates along the moving channel under the action of the rotating sleeve.

[0010] Furthermore, the electronically controlled drive includes a rotary motor.

[0011] Furthermore, a sliding limiting component is provided between the moving cylinder and the fixed plate. The sliding limiting component includes at least one limiting rod, which is fixed to the fixed plate and slidably connected to the moving cylinder. The limiting rod is fixed to the moving cylinder and slidably connected to the fixed plate.

[0012] Furthermore, the movable cylinder includes a cylinder body sleeved on the rotating sleeve and a connecting plate extending outward along the outside of the cylinder body, the connecting plate being connected in cooperation with each limiting rod.

[0013] Furthermore, the outer wall of the rotating sleeve is provided with a threaded section and an installation section along its axial direction. The threaded section is threadedly connected to the inner wall of the moving cylinder. A first sealing explosion-proof sleeve is provided between the installation section and the inner wall of the moving cylinder. A second sealing explosion-proof sleeve is provided between the outer wall of the moving cylinder and the inner wall of the moving channel.

[0014] Furthermore, it also includes a position sensor for detecting the moving distance of the moving cylinder, with the position sensor fixedly installed relative to the male connector. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figure 1 , 2 As shown in Figures 3 and 4, an automatic dewatering belt device includes a male connector 700, a rotating sleeve 100, and a movable cylinder 200 arranged sequentially from the inside to the outside. The male connector 700 is used to connect with the female connector of the water belt. The rotating sleeve 100 is rotatably connected to the male connector 700 and is driven to rotate along the male connector 700 by an electronically controlled drive component. The movable cylinder 200 is slidably arranged along the through groove of the male connector 700, and the inner wall of the movable cylinder 200 is threadedly connected to the outer wall of the rotating sleeve 100. The rotation of the rotating sleeve 100 drives the movable cylinder 200 to move toward the female connector, which is used to push the spring clip inside the female connector to unlock the female connector from the male connector 700.

[0019] Currently, there are also automatic hose dewatering devices installed on firefighting robots in existing technologies, such as the patent application number CN202020075399.0. The principle is also to use an electric drive to move the top plate, thereby unlocking the spring-loaded retaining element (spring clip) inside the female hose connector. However, the movement of the top plate is driven by the moving end of a push rod motor. Since the top plate is an annular plate, this method is equivalent to a single point on the top plate being pushed, causing the entire top plate to move along the male connector 700 (cylindrical). This method suffers from the problem of uneven movement.

[0020] Based on this, this application further improves the automatic dehydration belt device by adopting an inner and outer sleeve design, incorporating a male connector 700 (tubular structure), a rotating sleeve 100, and a movable cylinder 200. This layout utilizes surface force and the rotation of the rotating sleeve 100, along with a threaded connection, to move the movable cylinder 200 smoothly. This allows the movable cylinder 200 to push against the spring clips within the female hose structure, facilitating the unlocking of the male connector 700 and the female connector, and enabling automatic dehydration. The attached drawings of this application show the connection relationship between the device and the female hose connector. The mating relationship between the female hose connector and the male connector 700 can be referenced in prior art CN202020075399.0. Figure 3 , 4 As shown, the female hose connector is equivalent to the female connector in this patent, the spring snap is equivalent to the spring limiting member in this patent, the male connector 700 is equivalent to the male connector 700 in this patent, and the moving cylinder 200 is equivalent to the top plate in this patent. Thus, the snap-fit ​​and disconnection states of the automatic dewatering hose device of this application and the hose can be demonstrated.

[0021] In this application, based on the same unlocking principle, the movement of the movable cylinder 200 used to pry open the spring clip inside the female connector is set to be electrically driven. The rotating sleeve 100 rotates under the condition of electric drive (such as a hollow shaft brushless motor, a motor and drive mechanism cooperation method, etc.). Through the threaded connection, the movable cylinder 200 can be driven to move towards the female connector, thereby prying open the spring clip inside the female connector. This can unlock the female connector and the male connector 700 to complete the automatic dehydration belt, eliminating the need for manual dehydration and improving safety.

[0022] To facilitate the installation of the male connector 700, rotating sleeve 100, and moving cylinder 200, this application also provides an installation housing. The installation housing covers the male connector 700, rotating sleeve 100, moving cylinder 200, and electrical control drive components. This facilitates the installation of each component while also meeting explosion-proof requirements and protecting the electrical control drive components. It eliminates the need to expose the electrical control drive components, allowing the fire-fighting robot equipped with the automatic dewatering belt device to be used in flammable and explosive environments.

[0023] To achieve the covering effect, specifically, the mounting housing includes a fixed plate 310 and a mounting plate 320 spaced apart. The fixed plate 310 and the mounting plate 320 are connected to each other or via connectors to form a mounting space 300. Figure 1 , 2 As shown in Figure 4, the mounting plate 320 extends outward along the end of the male connector 700 away from the female connector and connects with the male connector 700. The fixing plate 310 is arranged around the male connector 700 near the connection end between the male connector 700 and the female connector. The fixing plate 310 has a moving channel 312 that is intermittently arranged with the male connector 700. The fixing plate 310 and the mounting plate 320 are arranged opposite to each other. The end of the fixing plate 310 is provided with an extension section 311 that bends toward the mounting plate 320. The mounting plate 320 is also provided with a bent end that bends toward the fixing plate 310. The extension section 311 and the bent end are connected. An annular reinforcing plate 330 is also provided inside the bent section 321 and the extension section 311. Sealing rings are provided between the reinforcing plate 330 and the bent section 321 and the extension section 311 respectively. The bent section 321 and the extension section 311 are fixed by a clamp 340 at the joint position, so that the fixing plate 310 and the mounting plate 320 can form a relatively sealed installation space 300.

[0024] Based on the installation space 300, only a corresponding explosion-proof sealing structure needs to be set between the fixing plate 310 and the male connector 700 to achieve the explosion-proof effect within the installation space 300, facilitating the installation of the electronically controlled drive component. Therefore, this application positions the electronically controlled drive component within the installation space 300 to drive the rotating sleeve 100 to rotate within the installation space 300, and the moving cylinder 200 to slide within the installation space 300 and, under the action of the rotating sleeve 100, partially reciprocate along the moving channel 312. For example... Figure 1 As shown, the male connector 700 consists of an interface section 720, a fixed section 710, and a water pipe section 730 connected in sequence. The interface section 720 is used to connect with the female connector. The end of the rotating sleeve 100 and the end of the fixed section 710 near the interface section 720 are basically flush. The water pipe section 730 is used to connect with the robot's water pipe (equivalent to the channel pipe in patent CN202211719511.X). The interface section 720 facilitates connection with the female water hose connector, the fixed section 710 facilitates the installation of various components, and the water pipe section 730 facilitates connection with the robot's upper pipeline.

[0025] The rotating sleeve 100 fits against the outer wall of the fixed section 710. Multiple sealing rings are provided between the rotating sleeve 100 and the outer wall of the fixed section 710 to achieve sealed rotation. The rotating sleeve 100 can be rotatably connected to the mounting space 300 via a bearing (reinforcing plate 330), and then driven to rotate by an electrically controlled drive component. The electrically controlled drive component can be a gear ring mounted on the rotating sleeve 100, a gear meshing with the gear ring, and a motor coaxially mounted with the gear. The motor is fixed within the mounting space 300. When the motor operates, the rotation of the rotating sleeve 100 is driven by the engagement of the gear and gear ring. The rotation of the rotating sleeve 100 drives the movement of the movable cylinder 200, which is used to push the spring clip of the female connector.

[0026] To simplify the structure of the electronically controlled drive component, the electronically controlled drive component in this application is a rotary motor 600. For example... Figure 1 , 2 As shown in Figure 4, the rotating motor 600 is a hollow shaft brushless motor (or hollow brushless motor). The rotating sleeve 100 is directly fixed to the hollow shaft of the rotating motor 600. The rotating motor 600 is fixed in the installation space 300. When the rotating motor 600 rotates, it can directly drive the rotating sleeve 100 to rotate. No other connecting structure is required, which simplifies the installation.

[0027] The movable cylinder 200 moves within the installation space 300. The movement of the movable cylinder 200 can be limited in various ways. Therefore, this application provides a sliding limiting member between the movable cylinder 200 and the fixed plate 310. The sliding limiting member includes at least one limiting rod 230. The limiting rod 230 is fixed to the fixed plate 310 and slidably connected to the movable cylinder 200, or the limiting rod 230 is fixed to the movable cylinder 200 and slidably connected to the fixed plate 310. The limiting rod 230 is equivalent to a sliding rod. By ensuring that either the limiting rod 230, the fixed plate 310, or the movable cylinder 200 is fixed, and the other is slidably connected, the movable cylinder 200 can slide within the installation space 300. Figure 4 As shown, this application provides multiple limiting rods 230. The length direction of each limiting rod 230 is parallel to the axial direction of the male connector 700, the rotating sleeve 100, and the moving cylinder 200, wherein the axes of the male connector 700, the rotating sleeve 100, and the moving cylinder 200 are collinear. Each limiting rod 230 is fixed to the fixing plate 310 and slidably connected to the moving cylinder 200. Based on the limiting rods 230, the movement direction of the moving cylinder can be restricted.

[0028] To facilitate the limiting and sliding of the movable cylinder 200, the movable cylinder 200 of this application includes a cylinder body 210 sleeved on the rotating sleeve 100 and a connecting plate 220 extending outward along the outside of the cylinder body 210. The connecting plate 220 is connected in cooperation with each limiting rod 230. Figure 1 , 2As shown in Figure 4, the connecting plate 220 is located at the end of the cylinder 210 away from the female connector and extends outward, making the moving cylinder 200 resemble a T-shaped cylinder structure as a whole, and each limiting rod 230 is slidably connected to the connecting plate 220.

[0029] To further improve the explosion-proof effect of the installation space 300 in this application, a threaded section 120 and an installation section 110 are provided along the axial direction on the outer wall of the rotating sleeve 100. The threaded section 120 is threadedly connected to the inner wall of the moving cylinder 200. A first sealing explosion-proof sleeve 400 is provided between the installation section 110 and the inner wall of the moving cylinder 200, and a second sealing explosion-proof sleeve 500 is provided between the outer wall of the moving cylinder 200 and the inner wall of the moving channel 312. Figure 1 , 2 As shown in Figure 4, the second sealing explosion-proof sleeve 500 is limited by the groove structure provided on the fixing plate 310, the first sealing explosion-proof sleeve 400 is fixed to the rotating sleeve 100, and the cylinder body 210 of the moving cylinder 200 moves within the gap formed by the first sealing explosion-proof sleeve 400 and the second sealing explosion-proof sleeve 500, further ensuring the sealing explosion-proof effect within the installation space 300.

[0030] To detect the moving distance of the movable cylinder 200, this application also includes a position sensor for detecting the moving distance of the movable cylinder 200, the position sensor being fixedly installed relative to the male connector 700. For example... Figure 1 , 2 As shown in Figure 4, the position sensor is fixed on the reinforcing plate 330 to detect the moving distance of the connecting plate 220 of the moving cylinder 200. The position signal detected by the position sensor can be transmitted to the controller (PLC controller) of the fire-fighting robot to facilitate starting the rotating motor 600, stopping the rotating motor 600, or controlling the rotation direction of the rotating motor 600.
