Description

Technical Field

[0001] This utility model relates to the field of fire-fighting pressurization and stabilization technology, and in particular to a vertical fire-fighting pressurization and stabilization structure. Background Technology

[0002] The fire-fighting pressure stabilizing structure acts as the "pressure guardian" of the fire-fighting water supply system. Its core function is to maintain stable daily pressure in the pipe network, ensuring that fire hydrants or sprinkler systems can immediately supply water in the early stages of a fire. Its working principle involves real-time monitoring of the pipe network pressure using pressure sensors. When the pressure falls below a set lower limit, the pressure-stabilizing pump automatically starts, replenishing water and increasing pressure in the pipe network; when the pressure rises back to the upper limit, the pump automatically stops. This cycle repeats continuously, keeping the pipe network pressure within a safe range.

[0003] Existing fire-fighting pressure-stabilizing structures are mostly horizontal, such as the Chinese utility model patent with application number CN202423143657.1, entitled "A Dual-Power Fire Pump Set with Pressure Stabilizing Device," which is a horizontal structure. This type of structure occupies a large area and is inconvenient to install in narrow underground pump rooms. Furthermore, existing fire-fighting pressure-stabilizing structures often use a single-specification booster pump for water supply, which can easily lead to overpressure problems during the replenishment of small-flow fire-fighting water supply, affecting the safe operation of the fire-fighting system and the safety of firefighters. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a vertical fire-fighting pressurization and stabilization structure, which has a compact structure, small footprint, and can perform pressurization and stabilization more flexibly, quickly and safely according to the needs of use.

[0005] This utility model is achieved using the following technical solution: a vertical fire-fighting pressurization and stabilization structure, comprising a base, a first pressurization pump assembly, a second pressurization pump assembly, a water collection pipe, a pressure tank, and a connecting pipe. The first pressurization pump assembly and the second pressurization pump assembly are respectively fixed to the upper front part of the base. The pressure tank is fixed to the upper rear part of the base by a bracket. The water collection pipe is located above the middle part of the base. The rear ends of the first pressurization pump assembly and the second pressurization pump assembly converge through the water collection pipe and are connected to the pressure tank through the connecting pipe. The first pressurization pump assembly and the second pressurization pump assembly are vertically installed, and the drainage capacity of the first pressurization pump assembly is less than that of the second pressurization pump assembly.

[0006] Furthermore, the first booster pump assembly includes a first booster pump body and a first booster pump motor fixed to the top of the first booster pump body. The front end of the first booster pump body is fixedly connected to a first booster pump inlet, and the rear end of the first booster pump body is fixedly connected to a first booster pump outlet.

[0007] Furthermore, the second booster pump assembly includes a second booster pump body and a second booster pump motor fixed to the top of the second booster pump body. The front end of the second booster pump body is fixedly connected to a second booster pump inlet, and the rear end of the second booster pump body is fixedly connected to a second booster pump outlet.

[0008] Furthermore, the water collection pipeline includes a water collection pipe, a sealing blind flange, a water collection pipe outlet, and a water collection pipe inlet. The two water collection pipe inlets are fixedly connected to the front end of the water collection pipe, the water collection pipe outlet is fixedly connected to the rear end of the water collection pipe, the sealing blind flange is fixed at both ends of the water collection pipe, and the water collection pipe outlet is connected to the connecting pipe via a flange.

[0009] Furthermore, the pressure tank includes a pressure tank body and a pressure tank inlet fixed to the bottom of the pressure tank body.

[0010] Furthermore, a first valve is connected between the outlet of the first booster pump and the inlet of the water collection pipe via a flange.

[0011] Furthermore, a second valve is connected between the outlet of the second booster pump and the inlet of another water collection pipe via a flange.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The vertical fire-fighting booster and pressure-stabilizing structure of this utility model makes the structure more compact and occupies less space by vertically installing the first booster pump assembly and the second booster pump assembly; by setting two booster pump assemblies with different drainage capacities, it can more flexibly boost and stabilize pressure according to the needs of use, thereby avoiding the overpressure problem that is easy to occur during the replenishment of small flow fire-fighting water supply, achieving boost and pressure stabilization more quickly and safely, and ensuring the safe operation of the fire-fighting system and the safety of firefighters.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0018] The purpose of this invention is to address the shortcomings of existing technologies by providing a vertical fire-fighting pressurization and stabilization structure.

[0019] Example 1

[0020] This embodiment provides a vertical fire-fighting pressurization and stabilization structure, referring to... Figure 1 As shown, the system includes a base 1, a first booster pump assembly 2, a second booster pump assembly 3, a water collection pipe 4, a pressure tank 5, and a connecting pipe 6. The first booster pump assembly 2 and the second booster pump assembly 3 are fixed to the upper front part of the base 1, and the pressure tank 5 is fixed to the upper rear part of the base 1 by a bracket. The water collection pipe 4 is located above the middle part of the base 1. The rear ends of the first booster pump assembly 2 and the second booster pump assembly 3 converge through the water collection pipe 4 and are connected to the pressure tank 5 through the connecting pipe 6. The first booster pump assembly 2 and the second booster pump assembly 3 are vertically installed, with a compact structure and small footprint. The drainage capacity of the first booster pump assembly 2 is less than that of the second booster pump assembly 3. By setting up two booster pump assemblies with different drainage capacities, the first booster pump assembly 2 and the second booster pump assembly 3 work together to boost pressure in the early stage of boosting. When the pressure approaches the preset pressure, the second booster pump assembly 3 is turned off, and only the first booster pump assembly 2 with the smaller drainage capacity is used for boosting. This can avoid the overpressure problem that is easy to occur during the replenishment of small flow fire water supply, and achieve boosting and stabilizing pressure more quickly and safely.

[0021] Reference Figures 2-3As shown, the first booster pump assembly 2 includes a first booster pump body 21 and a first booster pump motor 22 fixed to the top of the first booster pump body 21. A first booster pump inlet 23 is fixedly connected to the front end of the first booster pump body 21, and a first booster pump outlet is fixedly connected to the rear end of the first booster pump body 21. The second booster pump assembly 3 includes a second booster pump body 31 and a second booster pump motor 32 fixed to the top of the second booster pump body 31. A second booster pump inlet 33 is fixedly connected to the front end of the second booster pump body 31, and a second booster pump outlet is fixedly connected to the rear end of the second booster pump body 31. The first booster pump assembly 2 and the second booster pump assembly 3 operate independently. The water collection pipeline 4 includes a water collection pipe 41, a blind flange 42, a water collection pipe outlet 43, and a water collection pipe inlet 44. Two water collection pipe inlets 44 are fixedly connected to the front end of the water collection pipe 41, and the water collection pipe outlet 43 is fixedly connected to the rear end of the water collection pipe 41. The blind flange 42 is fixed to both ends of the water collection pipe 41. The water collection pipe outlet 43 is connected to the connecting pipe 6 via a flange. The pressure tank 5 includes a pressure tank body 51 and a pressure tank inlet 52 fixed to the bottom of the pressure tank body 51. A first valve 24 is connected to the outlet of the first booster pump and the water collection pipe inlet 44 via a flange, and a second valve 34 is connected to the outlet of the second booster pump and the other water collection pipe inlet 44 via a flange. The first valve 24 and the second valve 34 can be gate valves as used in the prior art.

[0022] This utility model discloses a vertical fire-fighting pressurization and stabilization structure. It utilizes the energy storage function of a pressure tank 5 to control the start and stop of the first booster pump assembly 2 and the second booster pump assembly 3 according to pressure changes in the water supply system, thereby achieving pressurization and stabilization. Initially, due to drainage, pipe leakage, or other issues in the water supply system, the pressure is lower than P1, and both booster pump assemblies start to replenish water into the pressure tank 5. As the pressure gradually increases, when it reaches the set value P2, the booster pump assemblies stop operating. This process repeats, allowing the booster pump assemblies to operate intermittently between pressures P1 and P2. By vertically installing the first booster pump assembly 2 and the second booster pump assembly 3, the structure is more compact, occupying less space. By setting two booster pump assemblies with different drainage capacities, pressurization and stabilization can be performed more flexibly according to usage needs, thus avoiding overpressure problems during the replenishment of small-flow fire-fighting water supply. This achieves pressurization and stabilization more quickly and safely, ensuring the safe operation of the fire-fighting system and the safety of firefighters.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
