Description

Technical Field

[0001] The utility model belongs to the field of fire-fighting devices, in particular to a mobile fire-fighting device for a water photovoltaic power station. Background Art

[0002] Floating photovoltaic power stations utilize floating structures to mount photovoltaic modules, inverters, and other power generation equipment on the water surface, converting solar energy into electricity through the photovoltaic effect. This approach avoids land use, reduces land acquisition costs, and is particularly suitable for areas with limited land resources. It can also increase power generation. Water has a cooling effect on photovoltaic modules, suppressing surface temperature increases and thus increasing power generation. Installing photovoltaic power stations on water can also reduce evaporation and algae growth, theoretically reducing evaporation from the water surface and inhibiting algae growth in the water, thus contributing to water resource conservation. Although photovoltaic power stations are located in water, they contain a large amount of electrical equipment, such as photovoltaic panels, inverters, and DC combiner boxes. These devices can suffer from short circuits, overloads, and other faults over extended periods of operation or when exposed to external environmental influences, potentially causing fires. Photovoltaic panels themselves are difficult to burn, but cables and inverter casings within the power plant are susceptible to fires caused by lightning strikes or arson, which can still pose a threat to the power plant. Furthermore, floating photovoltaic power plants rely on floating devices to support the panels. If these floating devices are damaged or fail, the panels could sink into the water, causing a short circuit or fire. Environmental factors can also affect the safe operation of the floating photovoltaic power plant, increasing the risk of fire. Therefore, floating photovoltaic power plants require firefighting equipment, but existing firefighting equipment is limited in adaptability and inconvenient for use in different waters.

[0020] The mobile fire fighting device for a water photovoltaic power station described in this embodiment is as follows: Figure 1 As shown, it includes a box body 1, and a moving component 15 is provided at the bottom of the box body 1, which is convenient for moving on the water surface, so as to facilitate fire extinguishing at different locations;

[0021] The mobile assembly 15 is a prior art and can be a small boat, an assault boat or a motorboat. It can be driven manually or remotely controlled by a remote control device.

[0022] The mobile assembly 15 may adopt patent number CN201610044964.5, which is titled as a portable inflatable water mobile platform, comprising a carrying platform and an air bag connected to the carrying platform for providing buoyancy, a propulsion mechanism being hingedly or detachably connected to the carrying platform, and a first chamber being provided on the carrying platform. During installation, the box 1 is fixed to its 11 platforms;

[0023] The mobile assembly 15 may also adopt the patent number CN201880018748.0, which is named as a water mobile device and a water mobile device. The water mobile device 10 includes: a body 100, a first propulsion generating unit having a propeller 211 and a motor 212, a second propulsion generating unit having a propeller 221 and a motor 222, and a control unit 30. When installing, the box 1 can be fixed on the upper surface 100T;

[0024] A partition 10 is fixed horizontally in the box body 1. The partition 10 divides the box body 1 into a first cavity and a second cavity from top to bottom. A pumping assembly is provided in the second cavity to facilitate the use of water from the water area of ​​the photovoltaic power station for fire extinguishing. The water is pumped into the second cavity of the box body 1 by the pumping assembly for storage, thereby saving costs and effectively completing fire extinguishing.

[0025] The second cavity is connected to the first cavity via a water inlet pipe 14. The water inlet pipe 14 in the first cavity is connected to a first filter assembly for filtering fresh water and a second filter assembly for filtering seawater via a tee pipe 13. This facilitates the photovoltaic power station to utilize water resources in different water areas when it is located, thereby reducing costs, completing fire extinguishing, and preventing water quality from affecting the use of photovoltaic equipment.

[0026] The second cavity is provided with a detection component for detecting the salt content in the water, so as to facilitate selection of the first filter component or the second filter component according to the detected salt content;

[0027] The water outlet ends of the first filter assembly and the second filter assembly are both provided with a second water outlet pipe 7, which is connected to the spray assembly 5 through the two-way pipe 6, and an adjustment component for adjusting the spray angle of the spray assembly 5 is provided on the top of the box body 1, so that the drawn water is filtered and sprayed on the fire point, and the fire points at different positions are quickly extinguished under the drive of the moving component 15 and the adjustment component, thereby improving the effect and reducing the difficulty of fire extinguishing;

[0028] The water pumping component is a water pump 11, and the water pump 11 can be an existing water pump;

[0029] The detection component uses an existing water quality salinity sensor. This type of sensor assesses the salt content in water by measuring the charge or conductivity of ions in the water. It has two working principles. One is inductive measurement, which uses a generator to generate an alternating magnetic field in the primary coil, generating an induced current in the medium. The intensity of the induced current depends on the ion concentration in the medium. The induced current generates another magnetic field in the secondary coil. The receiver measures the induced current on the coil and thus determines the salinity of the medium.

[0030] A controller is provided in the first cavity, and is electrically connected to the spray assembly 5, the water pump 11, the motor 17, and the detection assembly, and is used to receive signals from the detection assembly to control the opening of the tee pipe 13 and the tee pipe 2 6, as well as to control the opening and closing of the spray assembly 5, the water pump 11, and the motor 17;

[0031] The other is conductivity measurement, which indirectly reflects the salt content by measuring the conductivity of water, because salt increases the conductivity of water;

[0032] The three-way pipe 13 and the two-way pipe 6 are both equipped with electric control valves, which facilitate the selection of different filter components according to the water drawn in.

[0033] A first filter screen 12 is vertically arranged in the second cavity, and the first filter screen 12 divides the second cavity into a first area and a second area from left to right. The pumping assembly is arranged in the first area, and the water inlet pipe 14 is located in the second area, so as to facilitate re-filtration of the water pumped into the second cavity, and then transport the filtered water to the first filter assembly or the second filter assembly through the water inlet pipe 14, so as to reduce blockage or damage caused by excessive impurities in the water.

[0034] The second filter assembly includes a housing 2, in which a reverse osmosis membrane 3 is fixed. The water inlet end of the reverse osmosis membrane 3 is connected to a tee pipe 13 via a first water outlet pipe 9. The water outlet end of the reverse osmosis membrane 3 is provided with a second water outlet pipe 7 and a sewage pipe 4, which facilitates filtering and separating the salt in the pumped seawater, thereby reducing the salt content in the water during fire extinguishing, and further reducing the corrosion caused to the photovoltaic power station equipment during fire extinguishing, thereby reducing the loss cost;

[0035] The reverse osmosis membrane 3 is a prior art. When the membrane is used to separate fresh water and sea water, water molecules in the fresh water will penetrate toward the sea water side under the action of osmotic pressure. When a pressure greater than the osmotic pressure is applied to the sea water side, the situation will be reversed, so that the water molecules in the sea water will penetrate toward the fresh water side through the membrane. The ions generated by the salt in the sea water cannot pass through the membrane due to their large volume, thereby achieving the separation of water molecules and salt molecules to obtain fresh water.

[0036] The first filter assembly includes a housing 2, with a second filter screen 8 horizontally arranged inside the housing 2. The second filter screen 8 divides the interior of the housing 2 into an upper area and a lower area from top to bottom. The lower area is connected to a tee pipe 13 via a first water outlet pipe 9. The upper area is provided with a second water outlet pipe 7 for discharging filtered water, so as to further filter impurities in the water, thereby preventing blockage during jet extinguishing that affects the fire extinguishing effect.

[0037] The housing 2 , the second water outlet pipe 7 and the first water outlet pipe 9 in the first filter assembly and the second filter assembly are two identical components, not one component.

[0038] The spray assembly 5 includes a nozzle 21, and fixed plates 22 are provided on the left and right sides of the nozzle 21 to clamp the nozzle 21. A guide rod 20 is provided between the nozzle 21 and the fixed plate 22 to enable the nozzle 21 to rotate freely forward and backward. The bottom of the nozzle 21 is connected to the three-way pipe 26 through the connecting pipe 16, so that the water output from the first filter assembly or the second filter assembly can be sprayed to the fire point for extinguishing the fire. Then, the setting of the adjustment assembly can be used to drive the nozzle 21 to spray at multiple angles to achieve a better fire extinguishing effect.

[0039] The adjustment assembly includes a motor 17, which is installed at the top of the box body 1, and a through hole is opened at the top of the box body 1 for the output shaft of the motor 17 to pass through. A first gear 18 is installed on the conveying shaft of the motor 17 located outside the box body 1, and a second gear 19 is installed on the guide rod 20. The first gear 18 and the second gear 19 are in meshing shape, which makes it convenient for the motor 17 to drive the nozzle 21 to swing back and forth and spray water over a larger range.

[0040] The motor 17 is an underwater servo motor or other existing motors with good waterproofness, so as to facilitate precise control and increase service life;

[0041] A protective head is provided on the first water outlet pipe 9 in the shell 2 of the first filter assembly to reduce the entry of impurities, and the side wall of the protective head is inclined with the inside higher and the outside lower, so as to block the impurities accumulated in the lower area after being filtered by the second filter screen 8 and make them slide to both sides, thereby avoiding entering the first water outlet pipe 9 and causing blockage.

[0042] The working principle is to first pump water into the first area through the water pump 11, and complete the preliminary filtration through the first filter screen 12, and then detect the salt content in the water through the detection component, and select the first filter component or the second filter component according to the salt content. After selection, it is transported to the shell 2 through the water inlet pipe 14 and the first water outlet pipe 9, and then after completion of filtration, it is transported to the spray component 5 through the second water outlet pipe 7 at the water outlet end to spray and extinguish the fire. During the spraying process of the spray component 5, the spray position can be adjusted according to demand through the motor 17 or the moving component 15.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
