The present invention relate to a waterproof cloth used for firefighting and, more specifically, to a waterproof cloth for long-range spray including a barrel part connected to a firefighting water pipe, a waterproof gun including a spray nozzle spraying firefighting water coming from the barrel part, and a pressure raising filter having two or more dividing wings, inserted into the barrel part, and dividing an inner space of the barrel part into two or more spaces in a radial form. The waterproof cloth improves a spray range of firefighting water since the pressure raising filter minimizes a vortex in the barrel part and guides the firefighting water when the firefighting water comes into the barrel part. Accordingly, the spray range of the firefighting water is improved and the firefighting water is prevented from scattering. |
