Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, specifically to a novel connector assembly and fire protection system. Background Technology

[0002] In fire rescue and relief scenarios, multiple departments and equipment need to rely on a large number of signals to achieve coordination and cooperation.

[0003] However, multiple communication systems, such as satellite communication, wireless intercom, and private network transmission, often operate simultaneously at disaster relief sites. The intermingling of different protocols and frequency bands can easily cause signal interference, leading to frequent communication failures. Furthermore, in complex areas such as basements, large concrete buildings, and mountainous regions, signal obstruction and reflection, as well as the shielding effect of buildings and obstacles, can also cause communication disruptions or obstructions.

[0004] In addition, emergency rescue operations have extremely high requirements for real-time and stable communication, but traditional communication networks are prone to problems such as insufficient bandwidth and increased latency when multiple devices are accessed at high density, making it difficult to meet the requirements for stable signal transmission. Utility Model Content

[0005] The first aspect of this utility model aims to solve the problem of communication failure or obstruction by providing a novel connector assembly that can place communication units between mating connectors, thereby achieving both shielding against external signals and ensuring more stable signal transmission between the connectors. The main concept is as follows:

[0006] A novel connector assembly includes a first connector, a second connector, and a wireless communication module. The first connector and the second connector are plugged into each other to form an isolation cavity. The wireless communication module is disposed within the isolation cavity. The wireless communication module includes a first communication module disposed on the first connector and a second communication module disposed on the second connector.

[0007] This solution places the wireless communication module in the isolation cavity within the connector assembly, so that after the first connector and the second connector are plugged in and mated, the first communication module and the second communication module can complete the wireless connection within the connector assembly. The isolation cavity is made of metal material, which has good electromagnetic shielding performance and can effectively block interference from complex external signals, thereby improving the stability and accuracy of communication.

[0008] Preferably, the first and second connectors are cylindrical structures. The first connector includes a receiving groove, and the second connector includes an input port. The receiving groove accommodates the input port, and the first and second connectors are fastened together by a locking assembly; and / or the depth of the receiving groove is greater than the length of the input port extending into the receiving groove. The input port of the second connector extends into the receiving groove of the first connector, and the two connectors are fastened together by the locking assembly.

[0009] Preferably, the bottom of the receiving groove is provided with a first end face, and a first communication module is provided on the first end face; the top of the input port is provided with a second end face, and a second communication module is provided on the second end face; the first and second end faces are arranged opposite to each other. The isolation cavity is used for docking communication of the wireless communication modules, and placing the wireless communication modules on the two opposite end faces of the two connectors respectively makes the communication connection more sensitive and stable.

[0010] The second aspect of this invention aims to solve the technical problem of difficulty in identifying wireless communication modules within the isolation cavity after connector connection. Preferably, multiple sets of wireless communication modules are arranged along the circumferential direction on the first and second end faces; and / or, mounting grooves are formed on the first and second end faces, and wireless communication modules are arranged in the mounting grooves. This solution allows multiple wireless communication modules to be arranged on both end faces of the isolation cavity, enabling rapid positioning and adaptation of the multiple sets of wireless communication modules, and also improving the transmission stability of the wireless communication modules.

[0011] Preferably, the wireless communication module is a two-way infrared communication module, an RFID communication module, an NFC communication module, or a Zigbee module.

[0012] A fire protection system includes a novel connector assembly, a water nozzle, a fire truck, and several fire hoses. Each fire hose has a first connector and a second connector at both ends. The water nozzle and the fire truck are each equipped with a second connector and a first connector, respectively. The fire truck is connected to the water nozzle via the fire hoses. The connection between the hoses enables data transmission between adjacent hoses via a wireless communication module.

[0013] The third aspect of this invention aims to solve the technical problem of the difficulty in stably achieving long-distance wireless communication between the connector assemblies at both ends of a fire hose. Furthermore, the fire hose includes a hose body, within which are wires extending to both ends, connecting a first communication module and a second communication module. The connector assemblies at both ends of the hose body are wiredly connected via these wires, enabling long-distance communication data transmission.

[0014] Preferably, the fire hose further includes a power supply module, which includes a battery for supplying power to the first communication module and the second communication module via wires.

[0015] Preferably, it also includes a control center for communication with the fire truck, which communicates with the fire truck via a connector assembly. After the water nozzles, fire truck, and several fire hoses are connected via the connector assembly, the control center sends control information to the fire truck, enabling the fire truck to transmit information to the water nozzles via both wireless and wired methods, thus completing the communication.

[0016] The beneficial effects of this utility model are as follows:

[0017] The wireless communication module is placed in the isolation cavity within the connector assembly. After the first connector and the second connector are plugged in, the first communication module and the second communication module can complete the wireless connection within the connector assembly. The isolation cavity is made of metal material, which has good electromagnetic shielding performance and can effectively block interference from complex external signals, thereby improving the stability and accuracy of communication.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0024] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0025] Example 1

[0026] like Figures 1-2As shown, this embodiment provides a novel connector assembly, including a first connector 1, a second connector 2, and a wireless communication module 3. The first connector 1 and the second connector 2 are plugged together to form an isolation cavity 4. The wireless communication module 3 is provided in the isolation cavity 4. The wireless communication module 3 includes a first communication module 31 disposed on the first connector 1 and a second communication module 32 disposed on the second connector 2.

[0027] In this embodiment, the wireless communication module 3 is placed in the isolation cavity 4 within the connector assembly, so that after the first connector 1 and the second connector 2 are plugged in and engaged, the first communication module 31 and the second communication module 32 can complete the wireless connection within the connector assembly. The isolation cavity is made of metal material, which has good electromagnetic shielding performance and can effectively block interference from complex external signals, thereby improving the stability and accuracy of communication.

[0028] The first connector 1 and the second connector 2 are cylindrical structures. The first connector 1 includes a receiving groove 11, and the second connector 2 includes an input port 21. The receiving groove 11 is used to accommodate the input port 21. The first connector 1 and the second connector 2 are fastened together by a locking component 5. The input port 21 of the second connector 2 extends into the receiving groove 11 of the first connector 1, and the two connectors are fastened together by the locking component 5.

[0029] This embodiment can use a card-type fire hose coupling, specifically a KDK type hose coupling. Two or more sliders are connected by spring force or other means. The first connector is a female connector, which can be a KYK type female hose coupling, and the second connector is a male connector, which can be a KYKA type male hose coupling. The locking component 5 of the card-type fire hose coupling used in this embodiment relies on a mechanical latch and the driving force of an elastic element (such as a spring) to achieve rapid locking and sealing of the coupling. The receiving groove of the first connector has a snap-fit ​​mounting groove on its inner side wall near the outer end face. A mechanical snap-fit ​​is installed in the snap-fit ​​mounting groove by means of an elastic element. The side of the mechanical snap-fit ​​closest to the outside is provided with an arc surface so that the mechanical snap-fit ​​can be lifted after the input port 21 is inserted into the receiving groove 11. An abutment ring is provided at the outer end of the input port 21 of the second connector. The outer sleeve of the second connector is also provided with a slidable unlocking ring. In order to facilitate the movement of the unlocking ring, an auxiliary push plate is installed on the side of the unlocking ring away from the abutment ring. The outer wall of the abutment ring slides in cooperation with the inner wall of the receiving groove 11, and the outer wall of the unlocking ring slides in cooperation with the inner wall of the receiving groove 11.

[0030] When the input port 21 extends into the receiving groove 11, the abutment ring lifts the mechanical latch upward through the abutment arc surface. At this time, the elastic element is squeezed and compressed, and continues to extend. Under the action of the elastic element's reset force, the mechanical latch inserts into the gap between the abutment ring and the unlocking ring to complete the locking. When it is necessary to separate the connector assembly, push the unlocking ring towards the abutment ring so that the mechanical latch is lifted and unlocked. Then the second connector can be removed.

[0031] Example 2

[0032] like Figures 1-2 As shown, in this embodiment, the bottom of the receiving groove 11 is provided with a first end face 12, and the first end face 12 is provided with a first communication module 31. The top of the input port is provided with a second end face 22, and the second end face 22 is provided with a second communication module 32. The first end face 12 and the second end face 22 are arranged opposite to each other. The isolation cavity 4 is used for docking communication of the wireless communication module 3, and the wireless communication module 3 is respectively set on the two opposite end faces of the two connectors, so that the communication connection is more sensitive and stable.

[0033] Multiple sets of wireless communication modules 3 are arranged along the circumferential direction on the first end face 12 and the second end face 22; and / or, the first end face 12 and the second end face 22 are provided with mounting grooves, and the wireless communication modules 3 are arranged in the mounting grooves. In this solution, multiple wireless communication modules 3 can be arranged on both end faces of the isolation cavity 4. Multiple sets of wireless communication modules 3 can be quickly positioned and adapted, and the transmission stability of the wireless communication modules 3 can also be improved.

[0034] By setting up multiple sets of wireless communication modules and matching them with the end face gap, communication interruption caused by the failure of a single module can be avoided, while reducing signal attenuation.

[0035] The wireless communication module 3 adopts a bidirectional infrared communication module, an RFID communication module, an NFC communication module, or a Zigbee module, enabling the wireless communication module 3 to transmit signals bidirectionally at the same time.

[0036] The first end face 12 and the second end face 22 are arranged opposite to each other, and the depth of the receiving groove 11 is greater than the length of the input socket 21 extending into the receiving groove 11. The length difference between the receiving groove 11 and the input socket 21 ensures that a gap of 0.5~2mm is maintained between the first end face 12 and the second end face 22 within the isolation cavity 4, which separates the metal contact surfaces of the first end face 12 and the second end face 22, avoids the formation of a continuous shielding layer, and ensures that the signal is transmitted normally through the air medium.

[0037] For example, the transmission loss of RFID radio frequency signals in the 13.56MHz band in air is much lower than that in metal. The gap between the first end face 12 and the second end face 22 can reduce the signal attenuation between the first communication module 31 and the second communication module 32. The infrared signal of the bidirectional infrared communication module needs to be transmitted through an optical path. Both the first communication module 31 and the second communication module 32 are provided with a transmitter and a receiver. The gap between the first end face 12 and the second end face 22 can prevent metal from blocking the optical path of the transmitter and receiver.

[0038] Example 3

[0039] Based on Examples 1 and 2, such as Figure 3 As shown, the fire protection system provided in this embodiment includes a novel connector assembly, a water gun 8, a fire truck 7, and several fire hoses. The fire hoses are provided with a first connector 1 and a second connector 2 at both ends. The water gun 8 and the fire truck 7 are provided with a second connector 2 and a first connector 1, respectively. The fire truck 7 is connected to the water gun 8 through the fire hoses.

[0040] The connections between the components enable data transmission between adjacent water hoses via wireless communication module 3.

[0041] like Figure 4 As shown, the fire hose includes a hose body 6, within which are wires 61 extending to both ends. The wires 61 connect a first communication module 31 and a second communication module 32. The wires 61 connect the connector assemblies at both ends of the hose body 6, enabling long-distance communication data transmission. The hose body 6 uses wired communication via the wires 61 to directly transmit data via electrical signals, unaffected by electromagnetic interference at the site, ensuring stable transmission and reception of commands or status data.

[0042] The fire hose also includes a power supply module 62, which includes a battery. The battery is used to supply power to the first communication module 31 and the second communication module 32 through the wire 61.

[0043] In some application scenarios, water distributors are also installed between fire hoses for diversion. In order to ensure stable signal transmission, the water inlet and the water outlet of the water distributor are respectively equipped with a first communication module 31 and a second communication module 32.

[0044] It also includes a control center 9, which is used to communicate with the fire truck 7, and the fire truck 7 communicates and interacts through a connector assembly.

[0045] After the water gun 8, fire truck 7 and several fire hoses are connected through the connector assembly, the control center 9 sends the control information to the fire truck 7, enabling the fire truck 7 to transmit the information to the water gun 8 through both wireless and wired means, thus completing the communication.
