Description

The invention relates to the field of converting solar energy into electrical energy, in particular, to designs of semiconductor portable photoelectric stations (PFES) for powering various equipment and lighting, autonomous power supply of objects remote from the power supply network, farms, summer cottages and field work.

Known portable portable solar photovoltaic station for powering various equipment and lighting, including a case in the form of a suitcase with a solar battery mounted on it from the outside, and a battery placed inside it, a charge and protection controller for the battery, a control panel with connectors for connecting equipment, lamp with low consumption (see French patent No. 2746557, IPC H 02 J 7/35, publ. September 26, 1997).

Known portable portable solar photovoltaic station for powering various equipment and lighting, including a case in the form of a suitcase with a solar battery (SB) mounted on it from the outside and a battery (AB) placed inside it, a charge and battery protection controller, a control panel with connectors for connecting equipment, including a low-consumption fluorescent lamp, placed inside the suitcase (see French patent No. 2745434, IPC H 02 J 7/35, published on 08.29.1997 - prototype).

Known technical solutions have the following disadvantages:

- low power;

- the solar battery is built into the lid of the suitcase from the outside, while its movement is associated with the movement of the suitcase, which reduces the speed of the PFES installation in the optimal working position, it is inconvenient when choosing a place with the greatest sunlight and when the PFES is oriented relative to the Sun;

- solar panels are used with a maximum usable area commensurate with the lid area, while the increase in PFES power is associated with an increase in the dimensions of the suitcase;

- the location of the lamp is limited to a suitcase;

- low reliability of the design is associated with the location of the solar battery and external connectors on the outside of the suitcase, which does not exclude their mechanical damage, while in the working position, water, snow, dust, dirt, sand may hit the contact part of the connector, depending on climatic conditions and operating conditions, which can cause corrosion and impair contact reliability.

The invention solves the problem of creating a portable mobile PFES with increased power, reliability, durability and ease of use, transportation, repair, with optimal weight and dimensions, a significant service life (more than 20,000 hours) and made with the possibility of continuous round-the-clock work in various climatic and difficult adverse operating conditions in hiking conditions and mountainous terrain. By increasing the power, it was possible to electrically supply various loads - mobile radio equipment (small-sized equipment for household, medical and other purposes, including portable TVs, filters, pumps, etc.) with direct and alternating current. The availability of backup solar panels can reduce repair time and provide a low recovery time.

The problem is achieved in that in a portable solar photovoltaic station, including at least one solar battery and a battery located inside the housing, a charge and protection controller for the battery, a control panel with connectors for connecting the load, the solar battery is foldable with a waterproof rear housing, equipped with means for autonomous transfer, while the housing is made with a compartment for storing solar panels.

Preferably, the housing is in the form of a suitcase. Preferably, the solar battery is made in the form of a folding bag with a handle as a means for autonomous transfer.

It is advisable to make the control panel with at least two types of connectors for connecting loads, including with a cigarette lighter type connector for vehicles and with a plug connector for connecting a plug.

Preferably, the suitcase is made of moisture-proof frost-resistant plywood with a thickness of 5 to 10 millimeters.

It is advisable to have up to eight solar panels in the PFES.

The analysis of the prior art allows us to establish that the applicant has not found analogues characterized by signs identical to all the essential features of the claimed invention. The definition of the prototype made it possible to identify a set of essential (with respect to the technical result perceived by the applicant) distinctive features in the claimed object set forth in the claims. Therefore, the invention meets the requirement of "novelty" under applicable law. Information about the fame of the distinguishing features in the totality of the characteristics of the known technical solutions with the achievement of the same as the claimed device has no positive effect. Based on this, it was concluded that the technical solution meets the criterion of "inventive step".

Figure 1 presents PFES in the closed state. In Fig, 2 presents PFES in open form in preparation for work. Figure 3 shows the solar battery in the working position. Figure 4 shows the solar battery when folded. On Fig, 5 shows a solar battery when folded in position when offline transport.

A portable photovoltaic station includes one or more solar panels 1 placed inside a case made in the form of a suitcase 2, a rechargeable battery 3 (maintenance free), a charge and protection controller 4 of the rechargeable battery 3, a control panel 5 having a cigarette lighter connector 6, which provides connecting PFES to the vehicle’s battery, and plug 7 for connecting various equipment, including lamp 8.

The suitcase 2 consists of a base 9, a lid 10 with a stopper belt 11 for fixing in the open position, a compartment 12 for placing solar panels 1 during transportation, handles 13 for transfer, locks 14 for fixing the lid 10 and is made of thick waterproof frost-proof plywood (thickness 5 to 10 millimeters for use in adverse weather).

At the bottom of the suitcase 2 there is a rechargeable battery 3, a control panel 5 and a solar battery 1, at the upper level on the shelf 15 there is a charge and protection controller 4 and, if necessary, an economical fluorescent lamp 8 on a long wire. On the side surface of the suitcase 2 there is a plug 16 on the hinge for opening the cable entry 17 when connecting the solar battery 1. The solar panels 1 inside the compartment 12 are fixed with a belt 18.

The solar battery 1 has a folding structure (Fig. 3) and is made in the form of a portable folding bag (Figs. 4, 5) with a handle 20, fasteners 21, with a front moisture-proof film protective coating and a rear moisture-proof cover made of thick material, in particular from a special bag fabric. In the transport position and / or during storage, the solar batteries 1 are folded in the compartment 12 of the suitcase 2. It is possible to make the solar battery in the form of a flat backpack with straps for autonomous transfer (not shown in Fig.).

PFES can have from one to eight solar panels 1, of which one to three batteries can be placed during transportation and / or storage directly in the suitcase 2, the rest can be stored and transported separately.

On the control panel 5 there are connectors 6, 7 for connecting the solar battery and the load. At least two types of connectors 6, 7 are used to connect various loads. Connector 7 provides for the connection of a conventional plug, connector 6 for equipment (TV, radio, cell phone) connected via a cigarette lighter type connector for vehicles.

Battery 3 is used as an energy storage device and is designed for a nominal voltage of 12 volts. It is made in a sealed version with a helium electrolyte.

PFES works as follows. The suitcase 2 is transferred by the handles 13 to the place of operation in a closed form with a closed plug 16 on the cable entry 17. The cover 10 of the suitcase 2 is opened and fixed by a stopper belt 11. The removed solar panels 1 are laid out and connected to the connectors 6 of the control panel 5 through the cable entry 17 . Also through the cable entry 17 is connected to its sockets on the control panel 5 load (equipment or lamp 8).

The proposed technical solution provides in aggregate the generation of electric energy in the daytime by solar panels with a power of 40 or 80 W through the control panel 5 and its accumulation in the battery 3 (12 B) through the charge and protection controller 4. The energy stored in the battery 3 is used to power various equipment operating from 12 V, and / or to power the lamp 8 with low consumption, including fluorescent.

PFES can operate from a solar battery 1 with a capacity of 40 watts or 2 solar panels 1 with a total power of 80 watts. With an average load current of 1.2 A, the average PFES operating time is 14 hours a day. Through the connectors 6, 7 of the control panel 5, an inverter can be connected to obtain a voltage of 220 V (50 Hz). It is possible to change the configuration and accessories (two rechargeable batteries are connected in series and two solar panels are connected in series) to obtain a PFES with a voltage of 24 V. It is also possible to parallelly connect several PFES.

PFES has the following advantages:

- solar panels can be placed in any most illuminated place;

- solar panels with a useful area several times larger than the lid cover are used;

- it is possible to easily increase power and connect additional backup solar panels (up to 8 pieces);
