Abstract

The invention discloses a high-flow mooring fire pump ship with short-distance flight capability, and belongs to the field of fire fighting equipment. The invention aims to solve the problem that the floating boat pump is difficult to deploy and slow to launch under complex terrains. The device comprises a pump ship body, a large-flow water taking pump set, a flight module, a mooring cable and a control unit. The method is characterized in that a mooring cable connected with an ashore power supply is used for continuously supplying power to a flight module, so that a pump ship can fly over ground obstacles at a low altitude and rapidly and accurately land into a water area, and then a water surface mooring pump station mode is converted to provide large-flow water supply for a fire fighting truck. The deployment mode of traditional water taking equipment is changed, and quick response is achieved.

Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to a high-flow moored fire pump boat, and more particularly to an emergency fire-fighting equipment with short-range flight capability that can be quickly deployed to coastal, riverside, and reservoir water areas to provide stable, high-flow water supply for large-scale fires and cross-border fire-fighting support. Background Technology

[0002] Fighting large-scale fires, such as those in petrochemical plants, warehousing and logistics facilities, and high-rise buildings, hinges on ensuring a continuous and substantial water supply. Currently, water intake operations in complex waterways such as coastal shallows, slow-flowing inland rivers, and reservoir edges primarily rely on floating pumps, self-priming fire trucks, or fixed water intake docks. These methods have the following inherent drawbacks: Deployment limitations: Floating pumps need to be hoisted or manually carried into the water, making it difficult to quickly position them on mudflats, steep banks, and rocky areas; fire trucks are limited by their suction depth and geographical location. Insufficient flow rate: Traditional floating pumps typically have a flow rate of several hundred cubic meters per hour, which is insufficient to meet the extreme water supply demand of thousands of cubic meters per hour in large-scale fires. Poor stability: Under the influence of wind, waves or water flow, ordinary floating bodies are prone to displacement and capsizing, affecting the operation of the water intake head and even interrupting the water supply. Cross-border support difficulties: When rapid cross-border and cross-regional support is needed, heavy water intake equipment is difficult to deploy quickly due to limitations in infrastructure (such as docks and roads). Therefore, there is an urgent need for a dedicated fire-fighting water intake device that combines high flow rate, rapid deployment, and high stability to fill the existing technological gap and improve emergency rescue efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention The present invention aims to overcome the shortcomings of the prior art and solve the problems of slow deployment, low flow rate and poor stability of fire-fighting water intake equipment in complex aquatic environments, and to provide a special equipment that can quickly overcome ground obstacles and achieve stable large flow rate water intake. Technical solution of the present invention To achieve the above objectives, the present invention adopts the following technical solution: A high-flow-rate moored fire pump boat with short-range flight capability includes a main body of the pump boat, a water intake pump set, a flight module, a mooring and positioning module, and a control unit. The pump boat's main body is a sealed hull with sufficient buoyancy, and its bottom is equipped with at least four steerable bottom wheels for short-distance propulsion and loading / unloading positioning on land. The water intake pump set is fixedly installed on a base inside the pump vessel, and its technical parameters comply with the relevant fire pump standards for low-pressure, high-flow fire pumps. The pump inlet extends to the outside of the pump vessel through a large-diameter water pipe and is equipped with an anti-clogging filter screen; the outlet is connected to the onshore fire protection network through a quick-connect water pipe. The flight module includes multiple lift fans symmetrically arranged on the hull of the pump vessel. Each lift fan is driven by an independent electric motor. Under the coordination of the control unit, the lift fans provide vertical lift, enabling the entire pump vessel to achieve stable low-altitude hovering and short-distance transport capabilities. This is mainly used to overcome ground obstacles such as dams, gullies, and rugged terrain, expanding deployment flexibility. The mooring and positioning module consists of a power transmission and mooring cable and an auxiliary cable. One end of the cable is connected to the pump boat control unit via a waterproof quick-connect plug, and the other end is connected to the shore power supply equipment. The cable has buoyancy characteristics, which can reduce resistance during operation, and works together with the auxiliary cable to stabilize the pump boat at the predetermined water intake position under the set operating wind and wave conditions. The control unit is integrated within the pump boat's hull and includes a built-in control circuit, backup battery, and safety protection module. The control unit is electrically connected to the intake pump unit, each lift fan motor, and mooring cables, enabling start-up, operation monitoring, and remote control functions. The backup battery provides temporary power to the control system in the event of an unexpected external power outage. Beneficial effects of the present invention Compared with the prior art, the present invention has the following beneficial effects: Enhanced deployment capabilities: By integrating a flight module, the water intake equipment is able to overcome obstacles in complex terrain, changing the traditional deployment model and helping to reduce deployment time and manpower costs, while improving response speed. Stable water supply capacity: Utilizing standard-compliant high-flow fire pumps, a continuous water supply flow is provided. The wave-resistant mooring design combined with a filtration system helps ensure stable operation of the water supply system. High system reliability: Multiple safety designs help ensure continuous and reliable operation of the equipment in complex rescue environments, reducing the risk of water supply interruption due to malfunctions. Good practicality and adaptability: The structure is relatively simple, mainly using mature components, and the cost is controllable. It is suitable for fire support where conventional forces cannot respond quickly, as well as fire fighting and rescue in complex terrain environments such as coastal areas, rivers, and reservoirs, and has good application value.

[0005] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Example: See Figures 1 to 7 The present invention provides a high-flow-rate moored fire pump boat with short-range flight capability, the working process of which is as follows: Transportation and Preparation The equipment was transported to the shore near the fire site by transport vehicles. The operator connected one end of the standardized commercial floating power mooring cable (3) to the control unit (4) of the pump boat through a waterproof quick plug (9), and the other end to a high-power generator or fixed power source on the shore to complete the connection of power and signal. Flight deployment The operator starts the equipment via the control unit (4) or a remote terminal. Four lift fans (5) work simultaneously to generate vertical lift, smoothly raising the entire pump boat body (1). The flight altitude can be flexibly adjusted within a range of 0.5 meters to 10.0 meters above the ground, depending on the height of the terrain obstacles (such as dikes, gullies, and rocky areas). Under the traction and safety protection of the mooring cable (3), the operator controls the pump boat to fly at a low speed, directly crossing obstacles and accurately reaching the target water area. The bottom wheels (6) at the bottom of the equipment facilitate short-distance pushing and loading / unloading positioning on flat ground. Water surface positioning and water intake Upon reaching the target water area (0.5-7 meters deep), the power of the lift fan (5) is reduced to allow the pump boat to land smoothly on the water surface. The flight module is then completely shut off. The pump boat floats on its own buoyancy, with the inlet (10) submerged and the filter screen (13) beginning to intercept large impurities in the water. The water intake pump unit (2) is started, and water flows through the water pipe (8) into the wear-resistant pump body (12) for pressurization. It is then pumped from the outlet (11) through the fire hose to the onshore fire-fighting network, providing a large flow of water to the fire-fighting point. The mooring cable (3) and optional auxiliary cables securely hold the pump boat in the designated position to withstand wind and waves, ensuring the continuous and stable operation of the water intake. The control unit (4) monitors the equipment's operating status in real time. Safety and Recycling During operation, the control unit (4) monitors the operating status in real time and has multiple protections. If the external power supply is interrupted, the built-in backup battery can maintain the operation of the core system and trigger an alarm. After the mission is completed, the flight module is activated in reverse to fly the pump boat directly back to shore for landing. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
