Abstract

PURPOSE:To obtain a reliable and conventional radio communication circuit for fire fighting by a method wherein a radiotelephony transceiver is installed on the pump side, its antenna is attached on a nozzle or around it and they are connected by a cable which penetrates through the inside of hoses connected in a line by two or more hose joints. CONSTITUTION:A fire fighting pump 1, a nozzle 2 and two or more hoses 3 are connected in a line by male and female hose joints 4 and 5 each equipped on both ends of the hoses, and an electric circuit 6 is provided inside each hose. When the hoses are connected or disconnected, the electric circuits 6 are automatically connected or disconnected by connectors 7 each attached on both ends of the circuits 6. The cable ways are proof against water and pressure so that the electric conductivity and insulation are maintained whether or not the hoses are connected. The electric circuits 6 provided inside the lengthy line of the hoses is taken out from outlets 8 which are attached between one of the hoses and the pump and between one of the hoses and the nozzle, and electrically connects a transceiver 9 on the pump side and an antenna 10 on the nozzle side.

Description

【発明の詳細な説明】 この発明は消防用無線電話送受信装置の電気回神に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric circuit for a radio telephone transmitting/receiving device for fire fighting.

して回路を完成する。The configuration will be explained using a system diagram. In the diagram, 1 is a fire pump, 2 is a water cannon tip, and 3 is a fire hose. Reference numeral 3 usually consists of a series of fire hoses connected to male and female hose fittings 4 and 5 installed at each end of the hose, but an electric circuit 6 is installed inside each hose. The electric wire joints 7 installed and attached to both ends of each electric circuit not only prevent fire hoses, but also wireless telephones, which are connected to the radio waves of various systems at the fire scene 1. Interference noise is extracted from the hose from the electrical circuit extraction fitting 8 connected between the hose and the water cannon end, and connects the transmitting/receiving device 9 on the pump side and the antenna 10 on the water cannon end side to the outside of the hose. to complete the circuit.

利点もあり、又有線通In this way, the portable radio held by the worker supporting the water cannon is located close to the other party's transmitting/receiving equipment, so there is no radio interference caused by buildings, and it can be used in general radio communications.
Calls related to pump work have the advantage of being able to use wireless communications at specific wavelengths, and wired communications can also be used.
