INFLUENCE OF THE FORM-LAYOUT SOLUTIONS OF THE REMOVABLE COVER ON THE FUNCTIONAL PROPERTIES OF THE HEAT DETECTOR IP-105

Abstract

In this article the author considers the influence of the form-layout solutions of the removable cover of the detector on the functional properties of the sensitive element of the thermal detector of the model IP-105.

The relevance of the chosen topic is related to the increased requirements for the functionality and aesthetic appearance of modern interiors of public buildings, taking into account the tendencies of improving the quality of processing and expansion of the palette of materials used to decorate internal spaces, as well as increase the level of modern object furniture interiors filling, and the tendency to increase the number of electrical appliances and electrical equipment there is a problem of symbiosis of the implementation of the main functional tasks performed by thermal fire and detectors IP-105 and the needs of modern interior.

The idea is to update the typical protective removable cover of detectors that have been in service for a long time. It is assumed that the renovation of the protective removable cover is permissible in the event that the sensitive element of the detector has passed and has received confirmation that it is in working condition and can continue to be used. The main direction of this article is the proposal to replace typical protective removable covers of the case on detectors installed in rooms with the presence of children of preschool and school age groups.

For the development of a removable cover of the detector housing, the following specifications were chosen:

- stylization of a geometric shape under poppy seeds;

- the shape of the case meets the requirements for the design of rooms with children's themes;

- the possibility of convenient access to the sensitive element;

- simple construction of the lid mount with the possibility of fixing in the standard connectors of the detector;

- reliable fixation;

- the possibility of replacing the removable cover without the need to remove the base of the sensor with a sensitive element;

- the absence of direct contact with the processing in the area of the span of the sensor at the time of replacement of the housing or in the testing of the sensitive element.

In order to solve the problems, the author proposed a model that allows replacement of protective detector enclosures with a more modern alternative enclosure, MAK1 (detachable protective enclosure "Mak1"). It is proposed to perform it from similar materials.

So in work the results of the comparative analysis of engineering design solutions of the protective case of the fire detector are presented. The graphic diagrams, engineering visualization of the existing detector and the proposed fire cover were made by the IP-105 comparative analysis of the geometrical characteristics of the external removable cover of the fire detector IP-105 and the DPE “Mak1”.
