Description
Technical Field
The utility model relates to the technical field of fire-fighting equipment, in particular to a temperature-sensing magnetic power generation assembly.
Background
Russian 2330701 discloses a signal starter for use in an automatic fire extinguishing system, which signal starter is provided with an induction coil having an axial passage in a housing made of an insulating material and a connecting rod having a lower end movable up and down in the axial passage. The upper end of the connecting rod is fixed on the top of the shell by a locating pin made of thermal memory materials. The outgoing line of the induction coil is connected with the electric signal input end of the fire extinguisher through a binding post arranged on the insulating base by a wire. The induction coil of the signal starter is easy to generate induction current under the action of an external magnetic field, so that the connected fire extinguisher is in misoperation.
Chinese publication discloses the utility model patent: signal starting device, patent number: 2010202720998 this patent contains insulating shell and base, induction coil, take the connecting rod of magnet, the locating pin of locking the connecting rod, is provided with one end and induction coil lead-out wire and is connected, and the elastic contact of the other end can contradict with the magnet upper end of connecting rod when the connecting rod is locked by the locating pin and leaves induction coil central axial passageway and be connected two wires that form induction coil short circuit loop. The patent can solve the technical problem that the induction coil is not influenced by an external magnetic field and outputs an induction current signal, thereby causing unnecessary misoperation of the fire extinguisher. However, the patent still has two problems, 1, the vibration prevention is difficult to achieve, and the magnet falls off and is triggered by mistake due to the vibration; 2. the lightning is difficult to prevent, the magnetic field and micro-current are easy to generate when the lightning is generated, and the coil can be triggered under the condition that the magnet does not fall off.
Another Chinese patent is: temperature sensing magnetism electricity generation subassembly, patent number: 2019106642616, which provides shock and lightning protection. Based on this patent, the conductive element is designed as a copper wire with lower cost, and the copper wire can be better connected with the magnet.
Disclosure of Invention
The utility model aims to solve the defects of the prior art and provides a design scheme of a temperature-sensing magnetic power generation assembly, wherein an induction coil is free from the influence of an external magnetic field and can be limited in vibration prevention and lightning protection.
In order to achieve the above purpose, the temperature-sensing magnetic power generation assembly comprises an upper cover, a coil is arranged in the upper cover, a channel is arranged in the middle of the coil, a magnet is arranged above the channel, the top of the magnet is connected with a temperature-sensing sheet through a copper shaft, a spring is arranged on the outer side of the copper shaft, the temperature-sensing magnetic power generation assembly further comprises a copper wire, the copper wire is arranged against the inner wall of the upper cover and penetrates through the top of the magnet and is connected with the top of the magnet, and two terminals of the output end of the coil are directly connected in a normal state through the copper wire.
Preferably, the copper wire is bonded or welded to the magnet.
Compared with the prior art, the utility model has the advantages that:
1. the copper wire is propped against the magnet, so that the magnet is provided with transverse force, and is not easy to fall off after vibration, and the situation that the vibration is generated and false triggering is avoided is ensured;
2. the copper wires form a loop, so that the coil is not influenced when lightning stroke occurs;
3. the copper wire is lower in cost and is more tightly connected with the magnet.
Drawings
FIG. 1 is a schematic view of the overall structure of the present utility model;
in the figure: 1. the upper cover 2, the coil 3, the magnet 4, the temperature sensing piece 5, the spring 6, the copper wire 7, the base 8 and the copper shaft.
Detailed Description
The construction and principles of the present utility model will be readily apparent to those skilled in the art from the following description taken in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The upper cover is internally provided with a coil, the middle part of the coil is provided with a channel, a magnet is arranged above the channel, the top of the magnet is connected with a temperature sensing sheet through a copper shaft, the outer side of the copper shaft is provided with a spring, one end of the spring is connected with the magnet, the other end of the spring is connected with the top of the upper cover, a copper wire is further arranged in the upper cover and is arranged against the inner wall of the upper cover, the copper wire penetrates through the top of the magnet and is connected with the top of the magnet, and the copper wire is used for directly connecting two terminals of the output end of the coil in a normal state and is connected with the magnet in a bonding or welding mode.
The working principle of the utility model is as follows: when the temperature rises to the critical temperature value of the temperature sensing piece, the temperature sensing piece triggers, the magnet falls along the direction of the spring under the action of the spring force, the magnet enables the coil to generate induction current through the coil, and the induction current sends an electric starting signal to the outside.
The copper wire gives the magnet transverse force, is difficult to drop after vibration, guarantees that the vibration can not trigger by mistake, and simultaneously the copper wire forms a loop, and guarantees that the coil can not be influenced when lightning stroke occurs.
