Abstract

Veliki ljudski napredak i urbanizacija, posljednjih su desetljeća doveli do eksponencijalnog rasta broja vozila koje pojedinci posjeduju te kojima se prometuje svakodnevno diljem svijeta. Također, sve je više onih koji odlaze u veća mjesta ili gradove kako iz poslovnih pa tako i iz privatnih razloga, čineći tako javne površine (i prometnice) prljavima i stvarajući potrebu za njihovim čišćenjem i održavanjem.
Jedan od načina na koji se te površine mogu održavati čistima jest upravo korištenje kamiona koji su nadograđeni tako da postanu čistilice. Svaki takav uređaj mora biti sposoban skladištiti prikupljeni otpad, odnosno mora imati spremnik. Spremnik se sastoji od već spomenutog dijela u kojem se otpad skladišti te dijela u koji se sprema voda koja se koristi prilikom procesa čišćenja.
Prvi zadatak ovog rada dati je analizu tržišta kako bi se istražila i analizirala već postojeća rješenja ovakvog uređaja od strane konkurenata, potom ustvrditi podsustave uređaja i za kraj napravila funkcijska strukturu s ciljem olakšanja daljnje faze razvoja. Nakon toga, slijedi koncipiranje spremnika unutar kojeg se predlaže nekoliko rješenja i temeljem vrednovanja određuje ono najbolje, a s kojim će se prijeći na sljedeću fazu - fazu konstruiranja spremnika. U fazi konstruiranja napravljeni su potrebni proračuni i prikaz 3D modela spremnika. Na razvoju spremnika nastavit će se raditi u budućnosti, s toga ovo nije prikaz finalnog proizvoda.
Programski paket koji se koristio za izradu dijagrama funkcijske analize je draw.io koji je dio platforme Diagrams.net, dok se za izradu 3D modela, odgovarajuće dokumentacije i slika sa prikazima sila i opterećenja koristio programski paket Solidworks 2020.

Abstract (english)

The great progress of human civilization within the last few decades, as well as urbanization, have led to an exponential growth in the number of vehicles owned and driven by individuals all around the world. What is more, every day there are more and more people who go to larger towns or cities for either work or other private reasons, or both, thus making public surfaces (and roads) dirty and creating a need for their cleaning and maintenance.
A method that can be used for keeping these areas clean is by using trucks that have been altered to become sweepers. Each such device must be able to store the collected waste, in other words, it must have a container. The hopper consists of a part where the waste is stored and a water tank where the water used during the cleaning process is stored.
The first task of this paper is to do market research to get insight into existing solutions that competition has already come up with. After the market analysis, it is crucial to determine the subsystems of the device and create a functional structure in order to facilitate the further phase of the development. The next step is to create a concept of the hopper, which will provide several possible solutions and determine the best one that will be used for the next phase - phase of container construction. In this phase, calculations and a 3D model of the tank are necessary. The development of the container will continue in the future, therefore this is not a representation of the final product.
The program package used to create functional analysis diagrams is draw.io, which is part of the Diagrams.net platform, while the Solidworks 2022 program package was used to create 3D models, appropriate documentation and images with force and load displays.
