Description

Technical Field

[0001] This utility model relates to the field of fire-fighting water supply equipment technology, and in particular to a multi-channel independent controllable water collector. Background Technology

[0002] In fire and rescue operations, water collectors are high-flow-rate, highly redundant water supply hubs used to combine multiple water sources to solve the problem of insufficient pressure and flow from a single water source.

[0003] Currently, most water collectors are equipped with only a single outlet, which cannot achieve multiple water outlets. This results in insufficient coordinated operation capability of fire hoses, affecting fire extinguishing efficiency. Furthermore, existing water collectors usually do not have flow regulating valves, making it impossible to adjust the flow rate or quickly switch the water inlet or outlet. When a pipeline at a certain inlet fails, maintenance requires interrupting the water supply of the entire water collector, which seriously affects the continuity of firefighting operations. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-channel independently controllable water collector. This water collector has the function of multiple water outlets and can independently adjust the flow rate and on / off state, meeting the high-efficiency water supply needs of modern fire fighting operations.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a multi-channel independently controllable water collector, comprising a water collector body, a water collection chamber within the water collector body, at least three water inlets on one side of the water collector body, and at least two water outlets on the other side, wherein the water inlets and outlets are connected to the water collection chamber, and each water inlet and outlet is equipped with an independently controlled flow regulating valve.

[0006] As a further improvement of this utility model, the water inlet is provided with six ports and the water outlet is provided with four ports.

[0007] As a further improvement of this utility model, a flap check valve is also provided on the water inlet, and the opening direction of the flap check valve is towards the water collection chamber.

[0008] As a further improvement of this utility model, the main body of the water collector is a long columnar structure, with its two ends in the length direction defined as the front and rear sides. The water inlet is located on the left side of the main body of the water collector, and the water outlet is located on the right side of the main body of the water collector.

[0009] As a further improvement of this utility model, it also includes a pressure detection device, which is installed on the main body of the water collector and the detection end of the pressure detection device is connected to the water collection chamber.

[0010] As a further improvement of this utility model, a carrying handle is also provided on the top of the water collector body, and the carrying handle has a U-shaped structure.

[0011] As a further improvement of this utility model, a first quick-connect mechanism is provided on the water inlet; and a second quick-connect mechanism is provided on the water outlet.

[0012] As a further improvement of this utility model, the bottom of the water collector body is also provided with casters to facilitate the movement of the water collector body.

[0013] The beneficial effects of this utility model are as follows: by setting at least three water inlets and two water outlets, multiple water sources and multiple fire hoses can be connected simultaneously to achieve parallel water supply from multiple sources, meeting the complex tactical needs of multi-point attack, cover, and cooling. Each water inlet and outlet is equipped with an independently controlled flow regulating valve, which can realize rapid switching and pressure regulation of different pipelines. When any water inlet pipeline fails, the faulty pipeline can be shut down for maintenance without affecting the operation of other pipelines. Water supply capacity can be maintained through the pipelines of other water inlets to ensure the continuity of operations. Attached Figure Description

[0016] Marking description: Water collector body 1, water collection chamber 11, handle 12, caster wheel 13, inlet 2, first quick-connect mechanism 21, outlet 3, second quick-connect mechanism 31, flow regulating valve 4, flap check valve 5, pressure detection device 6. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 , 2 As shown, a multi-channel independently controllable water collector includes a water collector body 1, an inlet 2, an outlet 3, a flow regulating valve 4, a flap check valve 5, and a pressure detection device 6. The water collector body 1 is integrally cast from high-strength aluminum alloy and has an overall elongated columnar structure with a water collection chamber 11 inside.

[0019] The two ends along the length of the water collector body 1 are defined as the front and rear sides. At least three water inlets 2 are provided on the left side of the water collector body 1, and at least two water outlets 3 are provided on the right side of the water collector body 1. In this embodiment, six water inlets 2 are preferred, and four water outlets 3 are preferred. Both the water inlets 2 and the water outlets 3 are connected to the water collection chamber 11, and each of the water inlets 2 and water outlets 3 is equipped with an independently controlled flow regulating valve 4, which controls the flow rate and on / off state of the water inlets 2 and water outlets 3.

[0020] A flap check valve 5 is also installed on the inlet 2, and the opening direction of the flap check valve 5 is towards the water collection chamber 11. When a pipeline of a certain inlet 2 fails, the flow regulating valve 4 may not be closed in time, which may cause water in the water collection chamber 11 to flow back, affecting the pressure and flow of the outlet 3. The flap check valve 5 can effectively prevent water from flowing back from the inlet 2 into the pipeline.

[0021] The pressure detection device 6 is installed on the main body 1 of the water collector, and the detection end of the pressure detection device 6 is connected to the water collection chamber 11.

[0022] The top of the water collector body 1 is also provided with a carrying handle 12, which has a U-shaped structure and is used to lift the water collector for easy transfer.

[0023] The bottom of the water collector body 1 is also equipped with casters 13, which facilitates the movement of the water collector.

[0024] The carrying handle 12 and the wheels 13 are key innovations for heavy water collectors, enhancing fireground mobility and operational efficiency. They assist in transporting the water and improve the efficiency of rapid deployment.

[0025] The inlet 2 is equipped with a first quick-connect mechanism 21, which enables the inlet 2 to be quickly connected to the water supply pipeline; the outlet 3 is equipped with a second quick-connect mechanism 31, which enables the inlet 2 to be quickly connected to the outlet pipeline (such as a fire hose) through the first quick-connect mechanism 21.

[0026] During fire rescue operations, water inlet 2 can be connected to the pipelines of fire trucks, municipal fire hydrants, and portable pumps to achieve multi-source water supply and solve the problem of insufficient flow from a single water source.

[0027] When any of the inlet pipes 2 malfunctions, the flow regulating valve 4 of that inlet pipe 2 can be closed, while the other five inlets 2 maintain normal water supply to ensure uninterrupted water supply.

[0028] The four water outlets 3 can simultaneously connect to four water guns or hoses, meeting the complex tactical needs of multi-point attack, cover, and cooling. For example, in building fires, they can simultaneously conduct internal firefighting, external fire suppression, personnel cover, and equipment cooling. Case study: In a chemical plant fire, two water outlets 3 were used to extinguish the main fire, one was used to protect adjacent storage tanks, and one provided a cover water curtain for the attack team.

[0029] The core functions of the flow regulating valve 4 on each inlet 2 and outlet 3 are as follows:

[0030] 1. Multi-source integration: Different water inlets 2, such as municipal pipe network, fire truck, water tank, and hand pump, are controlled by independent flow regulating valve 4 to achieve rapid switching or parallel water supply;

[0031] II. Pressure Regulation and Protection: When the external water source pressure exceeds the system's pressure limit (e.g., 1.6MPa), the input pressure is reduced by throttling through the flow regulating valve 4 to prevent pipe bursting; the slow opening and closing of the flow regulating valve 4 can avoid pressure shock caused by sudden start and stop of water flow and suppress water hammer effect.

[0032] III. System Isolation Maintenance: After the flow regulating valve 4 of the single inlet 2 is closed, maintenance can be carried out on this pipeline without affecting the operation of other pipelines, ensuring the continuity of operations.

[0033] Pressure detection device 6 is the "vital signs monitor" of the on-site water supply system. Its functions go far beyond simple numerical display, directly affecting firefighting efficiency and operational safety. Its functions are as follows:

[0034] 1. Real-time water pressure monitoring: When using a hand pump to supply water, the output pressure of the hand pump is adjusted in real time based on the data from the pressure detection device 6 to avoid insufficient pressure causing the water gun range to be shortened and unable to penetrate the flame, and also to avoid excessive pressure increasing the risk of the water hose bursting.

[0035] II. Facilitates System Fault Diagnosis: Faults can be identified based on the appearance of the pressure detection device 6, enabling timely emergency measures. For example: 1. If the pointer vibrates violently, it indicates cavitation or blockage of the hand pump; immediately reduce the speed and check the filter. 2. If the hand pump pressure continues to drop, it indicates a broken water hose or leaking interface; close the flow regulating valve 4 at the corresponding outlet 3 and activate the standby pump. 3. If the hand pump pressure reaches zero but the pump is still running, it indicates a perforation in the water collection chamber 11 of the water collector; immediately switch to the standby water collector.

[0036] III. Providing Tactical Decision Support: Calculating real-time flow by combining pressure and caliber, using the formula: Q = 0.0008 × √P × d 2 (P is MPa, d is mm), for example, the flow rate of outlet 3 with a diameter of 65 mm is approximately 18.6 L / s at 0.8 MPa, and the flow rate of outlet 3 with a diameter of 80 mm is approximately 32 L / s at 1.0 MPa.

[0037] The above-described embodiments are only for illustrative purposes and are not intended to limit the present invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention shall still fall within the scope of the technical features of the present invention.
