Description

Technical Field

[0001] The utility model relates to the field of water supply equipment, in particular to an uninterrupted direct water supply equipment integrating industrial production and fire fighting. Background Art

[0002] Industrial production water and fire fighting water are essential. However, at present, industrial production water and fire fighting water are basically set up independently or an independent fire fighting water supply pool is separated in the industrial production water supply pool to ensure that fire extinguishing water can be provided at any time in case of a fire accident. However, with such a setting, when the fire fighting water is not used for a long time, the corrosion and damage of fire fighting equipment will be caused due to water quality deterioration, and it cannot be guaranteed that the fire fighting water can be effectively and timely used in case of a fire, delaying the fire fighting and rescue work and causing unnecessary losses. Although there is a production and fire fighting integrated water supply system with the patent number 201820182407.4, there are serious deficiencies in its structure. When the fire fighting water intake well is cleaned, the fire fighting pump and the industrial pump will be forced to stop running at the same time, resulting in the interruption of both industrial production water and fire fighting water. Since there is a shared partition wall between the two storage pools, and there are also shared partition walls between the two storage pools and the two water intake wells, two gate valves are set on the partition wall between the left and right storage pools and the fire fighting water intake well, so that both the left and right storage pools can supply water to the fire fighting water intake well, and neither of the two storage pools can directly supply water to the industrial water intake well. Instead, the water must be first supplied to the fire fighting water intake well and then through the overflow wall between the two wells to supply water to the industrial water intake well. In addition, setting the two gate valves in the water will also cause troubles in operation, maintenance and overhaul, with high costs. Moreover, the water inlet channel of the water pump is too tortuous and has sharp turns, resulting in high hydraulic resistance and being very unsafe. The water inlet process of the water pump must be stable and gentle, which is a basic common sense in the process design of the pump house. Because the tortuous and sharp turns of the water inlet channel will allow air to be incorporated into the water body, which may lead to adverse consequences such as water pump vibration, cavitation and water hammer, and will also reduce the hydraulic efficiency of the water pump, and its practical use value is not great. Therefore, it is imperative to improve and innovate in the structure. Content of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide an uninterrupted direct water supply equipment integrating industrial production and fire fighting, which can effectively solve the problems of uninterruptedly directly supplying water for industrial production and fire fighting, saving costs and improving efficiency.

[0004] The utility model relates to an uninterrupted direct water supply device integrating industrial production and fire fighting, which comprises a pump house, a water storage tank, a fire fighting water supply pipeline, an industrial water supply pipeline and a water pump. The water storage tank is arranged at the lower part of the pump house and is separated into two independent upper and lower spaces by the bottom plate of the pump house. The water storage tank is separated into an industrial water storage tank and a fire fighting water storage tank by a vertical partition wall in the middle. A water pump group and a fire fighting water supply pipeline and an industrial water supply pipeline communicated with the water pump group are installed in the pump house. The water pump group is composed of a first pump group and a second pump group. The first pump group is installed in the pump house above the industrial water storage tank, and the second pump group is installed in the pump house above the fire fighting water storage tank. A first industrial water supply pipeline and a first fire fighting water supply pipeline which communicate upwards are installed in the industrial water storage tank. The upper ends of the first industrial water supply pipeline and the first fire fighting water supply pipeline are communicated with the water inlet end of the first pump group. The water outlet end of the first pump group is respectively communicated with a first industrial water outlet pipeline and a first fire fighting water outlet pipeline.

The first fire fighting water outlet pipeline and the second fire fighting water outlet pipeline are communicated with each other. The lower ends of the fire fighting water supply pipelines extending into the industrial water storage tank and the fire fighting water storage tank are lower than the lower ends of the industrial water supply pipelines. The water storage capacity of the water storage tank corresponding to the height difference is the fire fighting safety guarantee water volume, that is, the maximum fire fighting water consumption in one time during the fire continuation time of the project, thus forming an uninterrupted direct water supply structure for industrial production and fire fighting.

[0008] By Figure 1Provided is a continuous direct water supply device integrating industrial production and fire protection, which includes a pump house 1, a water storage tank 2, a fire protection water supply pipeline, an industrial water supply pipeline and a water pump. The water storage tank 2 is arranged below the pump house 1 and is separated into two independent upper and lower spaces by the bottom plate of the pump house 1.

The water outlet end of the first pump group A is respectively connected to a first industrial water outlet pipeline 10-1 and a first fire protection water outlet pipeline 9-1. A second fire protection water supply pipeline 4 and a second industrial water supply pipeline 5a that communicate upward are installed in the fire protection water storage tank 2-2. The upper ends of the second fire protection water supply pipeline 4 and the second industrial water supply pipeline 5a are connected to the water inlet end of the second pump group B. The water outlet end of the second pump group B is respectively connected to a second industrial water outlet pipeline 10-2 and a second fire protection water outlet pipeline 9-2. The first fire protection water outlet pipeline 9-1 and the second industrial water outlet pipeline 10-2 are in a three-dimensional intersection. The first industrial water outlet pipeline 10-1 and the second industrial water outlet pipeline 10-2 are connected, and the first fire protection water outlet pipeline 9-1 and the second fire protection water outlet pipeline 9-2 are connected. The lower ends of the fire protection water supply pipelines extending into the industrial water storage tank 2-1 and the fire protection water storage tank 2-2 are lower than the lower ends of the industrial water supply pipelines. The water storage capacity corresponding to the height difference is the fire safety guarantee water volume, that is, the maximum fire protection water consumption during the fire duration of the project, constituting a continuous direct water supply structure for industrial production and fire protection.

[0009] To ensure the use effect and convenience, the first pump group A includes a first industrial pump 7-1, a second industrial pump 7-2 and a first fire protection pump 7-3. On the industrial water supply pipeline connected to the industrial water storage tank 2-1 by the first industrial pump 7-1, the second industrial pump 7-2 and the first fire protection pump 7-3, the same valves 6 are respectively installed. On the pipelines at the water outlet of the first industrial pump 7-1, the second industrial pump 7-2 and the first fire protection pump 7-3, the same one-way check valves 8 are respectively installed.

[0010] The second pump group B includes a third industrial pump 7-4, a second fire protection pump 7-5 and a third fire protection pump 7-6. On the fire protection water supply pipeline connected to the fire protection water storage tank 2-2 by the third industrial pump 7-4, the second fire protection pump 7-5 and the third fire protection pump 7-6, the same valves 6 are respectively installed. On the pipelines at the water outlet of the third industrial pump 7-4, the second fire protection pump 7-5 and the third fire protection pump 7-6, the same one-way check valves 8 are respectively installed.

[0011] The lower ends of the described first industrial water supply pipe 5 and second industrial water supply pipe 5a are provided with trumpet-shaped industrial pipe water intakes 5-1, and the lower ends of the first fire water supply pipe 4a and second fire water supply pipe 4 are provided with trumpet-shaped fire pipe water intakes 4-1.

[0012] The described first industrial water outlet pipe 10-1 is connected to the second industrial water outlet pipe 10-2 through an industrial connecting pipe 12, and at least one second valve 14 is installed on the industrial connecting pipe 12 to adjust the independent or combined water supply of the water pumps.

[0015] When the utility model is in normal use, there is no need to pump water from the storage pool into the pumping well and then supply water to the pipes from the pumping well. Instead, the fire water supply pipe and industrial water supply pipe can directly draw water from the storage pool 2 for industrial and fire use respectively. Due to the height difference between the fire pipe water intake and the industrial pipe water intake, there is always a certain amount of water in the storage pool that cannot be drawn by the industrial pipe water intake. The storage pool capacity corresponding to this height difference is the fire safety guarantee water volume, that is, the maximum fire water consumption in one time during the fire duration of the project. This part of the water volume can only be drawn by the fire pipe water intake for fire use; when the industrial storage pool and fire storage pool need to be cleaned, if any one of the storage pools is emptied, the second fire water supply pipe or the second industrial water supply pipe can still draw the required water volume from the industrial storage pool and fire storage pool for fire and industrial production use. Due to the height difference between the fire pipe water intake and the industrial pipe water intake, the principle is the same as described above, and the fire safety guarantee water volume is still retained, thus realizing uninterrupted direct water supply for industrial production and fire protection, with a simple structure, scientific and reasonable, saving investment and operation and maintenance costs, and improving the use efficiency.

[0016] In summary, when cleaning the reservoir, the present utility model can be carried out alternately and still directly supply water to fire fighting and industrial production without interruption. Moreover, the gate valves are all arranged in the pump house and not in the water, greatly reducing the costs of operation, maintenance and overhaul. Furthermore, the water inlet process of the water pump is stable and gentle, with small hydraulic resistance, safe and efficient, avoiding adverse consequences such as possible water pump vibration, cavitation and water hammer. Its structure is simple, novel and unique, the layout is compact, the civil engineering investment cost is low, it is convenient to manage and use, can be effectively used for industrial and fire fighting water use equipment, directly supply water to industrial production and fire fighting without interruption, reduce costs and increase efficiency, and has good social and economic benefits. It is a major innovation in water supply equipment.
