Description
Technical Field
The utility model belongs to the technical field of thermal power plant's safety protection, concretely relates to vacuum belt hydroextractor alarm device.
Background
A vacuum belt dehydrator in a limestone-gypsum wet desulphurization system of a thermal power plant is rotating equipment for removing moisture in gypsum, alarm prompting equipment is arranged before the rotating belt is started, a voice prompting device is required to be synchronously configured for ensuring personal safety, and related personnel are required to be prompted to be far away from the belt before the belt is started, so that mechanical injury is prevented.
In order to realize the voice prompt function, a mature method is to install a set of voice talkback and calling system, and the method usually has high investment and invisibly improves the operation cost of the power plant.
Disclosure of Invention
The utility model provides a vacuum belt hydroextractor alarm device causes personnel's mechanical injury accident when preventing to rotate the belt.
The technical scheme of the utility model is that: the utility model provides a vacuum belt hydroextractor alarm device, includes house service electric lead, alarm bell, with alarm bell parallel connection's power module, with the voice prompt of power module series connection, alarm bell is connected with house service power through house service electric lead.
And further, the service electric lead is connected with a fuse.
Further, the voice prompter is a loudspeaker with a recording function.
The scheme is further that the voice prompter is also connected with a warning lamp in series.
Further, the power module is a 220VAC/12VDC power module.
The utility model has the advantages that: the utility model discloses when starting the alarm bell before vacuum belt hydroextractor starts, automatic start voice prompt simultaneously, voice prompt broadcast recorded suggestion pronunciation in advance, if "vacuum belt hydroextractor is about to start, please notice" voice prompt, remind the site work personnel to keep away from vacuum belt hydroextractor, cause personnel's mechanical injury accident when preventing to rotate the belt, improve the operational safety.
Drawings
FIG. 1 is a schematic structural view of an alarm device of a vacuum belt dehydrator of the present invention;
wherein: 1. fuse, 2, alarm bell, 3, power module, 4, voice prompt, 5, service wire.
Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a person skilled in the art can, without any creative effort, fully implement the present invention.
The utility model discloses a concrete implementation mode is: as shown in figure 1, a vacuum belt hydroextractor alarm device, including house service wire 5, alarm bell 2, with alarm bell 2 parallel connection's power module 3, with the voice prompt 4 of power module 3 series connection, alarm bell 2 is connected with house service power supply through house service wire 5.
The utility model discloses further, be connected with fuse 1 on the house service electrical lead 5.
The utility model discloses further, voice prompt 4 is the megaphone of taking the recording function.
The utility model discloses further, voice prompt 4 is the series connection still has the warning light.
The utility model discloses further, power module 3 is 220VAC/12VDC power module.
The utility model discloses a theory of operation is: the power supply circuit for starting the alarm bell is connected with one power supply in parallel, the power supply connected in parallel is used as a 220VAC/12VDC power supply module power supply of the vacuum belt starting voice prompter, when the power supply circuit for starting the alarm bell is electrified, the vacuum belt starting voice prompter is electrified simultaneously, the voice prompter has a recording function, played voice is recorded in advance before installation, the 'vacuum belt dehydrator is about to start and please notice' prompt voice is played after starting, so that the function of automatically carrying out voice prompt before the vacuum belt is started is realized, field workers are awake to be away from the vacuum belt dehydrator, mechanical injury accidents of the workers caused by rotating the belt are prevented, the playing sound intensity of the voice prompting device can reach 90 decibels, and the prompt effect can be achieved in a noisy field environment.
While the preferred embodiments of the present invention have been described, it is to be understood that the invention is not limited to the precise embodiments described, and that equipment and structures not described in detail are understood to be practiced as commonly known in the art; any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention will still fall within the protection scope of the technical solution of the present invention by those skilled in the art without departing from the technical solution of the present invention.
