Description

Technical Field

[0001] The utility model relates to a fire pump house. Background Art

[0002] In traditional mine fire pump houses, the water storage facilities are usually installed indoors. This design has the following defects: indoor fire water tanks need to occupy valuable building areas, increasing construction costs and potentially affecting land use efficiency. At the same time, the construction materials, structural design, and supporting facilities (such as pipelines) of indoor fire water tanks will all increase construction costs. If the capacity is not properly designed, it will also lead to water resource waste, further increasing long-term operation costs.

[0003] To overcome the above defects, the prior art has proposed a solution of installing the fire water tank outdoors. This type of solution can save indoor space, reduce construction costs, and the complexity and construction difficulty of indoor structures. However, such solutions still have defects: the environment where the outdoor fire water tank is located is relatively harsh, and the stored fire water contains more impurities, which is easy to block the fire pipelines. Even if a filtering device is installed at the water inlet end of the fire outlet pipeline, there is still the problem of frequent replacement of the filtering device. Especially when the filtering device is located inside the fire water tank, it is very inconvenient to replace. Summary of the Utility Model

[0004] The utility model proposes a fire pump house with an external water tank, and its purpose is to solve the problems of more impurities in fire water and high replacement frequency of the built-in filtering device in the fire water tank.

[0005] The technical solution of the utility model is as follows:

[0006] A fire pump house with an external water tank includes a pump house building body and a fire water tank. A main water pump is installed inside the pump house building body. The fire water tank is connected with a fire water inlet pipeline and a fire water outlet pipeline. The main water pump is installed on the fire water outlet pipeline. The fire water tank is arranged on the roof of the pump house building body. A circulating pump and a filter are also installed inside the pump house building body;

[0007] The fire pump house also includes a filtered water inlet pipeline, a filtered water outlet pipeline, a backwash drainage pipeline, and an intermediate pipeline;

[0009] The water inlet end of the filter is also connected to the water inlet end of the backwash drainage pipeline. A second valve is also arranged on the backwash drainage pipeline;

[0010] The water outlet end of the filter is connected to the water inlet end of the filtered water outlet pipeline, and the water outlet end of the filtered water outlet pipeline is located at the top of the inner cavity of the fire fighting water tank. A fifth valve and a circulation pump are sequentially arranged on the filtered water outlet pipeline along the water flow direction;

[0011] The water outlet end of the filter is also connected to the water outlet end of the intermediate pipeline, and a third valve is provided on the intermediate pipeline;

[0012] A main water pump, a tee joint and a fourth valve are sequentially arranged on the fire fighting water outlet pipeline along the water flow direction. The tee joint is also connected to the water inlet end of the intermediate pipeline.

[0013] As a further improvement of the fire fighting pump house outside the water tank: a surrounding water trough is provided on the inner side wall of the fire fighting water tank. The periphery and bottom of the surrounding water trough are of a closed structure, and a detachable filter plate is installed at the top opening;

[0014] The water inlet end of the fire fighting water outlet pipeline is located inside the surrounding water trough.

[0015] As a further improvement of the fire fighting pump house outside the water tank: a rainwater gutter is also provided at the edge of the roof. An inclined drain trough is provided on the roof inside the rainwater gutter, and the water outlet end of the backwash drain pipeline is located above the drain trough.

[0016] As a further improvement of the fire fighting pump house outside the water tank: an overflow pipe is also provided on the fire fighting water tank. The water inlet end of the overflow pipe is located at the top of the inner cavity of the fire fighting water tank, and the water outlet end is located above the drain trough.

[0017] As a further improvement of the fire fighting pump house outside the water tank: a ventilation opening is provided at the top of the fire fighting water tank, and a rainproof cap is installed above the ventilation opening.

[0018] Compared with the prior art, the utility model has the following positive effects:

[0019] 1. The utility model filters the water in the fire fighting water tank through a circulation pump and a filter, thereby ensuring the cleanliness of the water quality and reducing the replacement frequency of the filter plate.

[0020] 2. The utility model also has a backwashing function, which reduces the replacement frequency of the filter element of the filter.

[0021] 3. The filter is located in the pump house, and it is more convenient to replace the filter element than the filter plate in the water tank.

[0022] 4. The surrounding water trough structure can further assist in purifying the water entering the fire fighting water outlet pipeline and avoid blockage of the pipeline.

[0023] 5. The fire fighting water tank is located at the top of the building body, which further reduces the floor area and cost. At the same time, the backwash water and overflow water are discharged from the roof uniformly and do not pass through the inside of the pump house, reducing the air humidity in the pump house and being beneficial to the stable operation of the electrical control equipment.

Detailed Description of the Preferred Embodiment

[0029] The technical solution of the present utility model will be described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0030] As Figures 1 to 3 , a fire fighting pump house with an external water tank includes a pump house building body and a fire fighting water tank 2.

[0031] The fire fighting water tank 2 is arranged on the roof of the pump house building body and is made of stainless steel. A rainwater gutter 1 is also provided at the edge of the roof. An inclined drainage trough 4 is arranged inside the roof within the rainwater gutter 1 for the rapid drainage of other equipment on the roof.

[0032] A main water pump 18 is installed inside the pump house building body, and a circulation pump 13 and a filter 16 are also installed.

[0033] The fire fighting water tank 2 is connected with a fire fighting water inlet pipeline 9 and a fire fighting water outlet pipeline 3, and the main water pump 18 is installed on the fire fighting water outlet pipeline 3. The fire fighting water inlet pipeline 9 is used to inject fire fighting water into the fire fighting water tank 2 through an external pumping device, and the fire fighting water outlet pipeline 3 conveys the fire fighting water to the water using end under the pressure of the main water pump 18.

[0034] Further, a water surrounding groove 11 is provided on the inner side wall of the fire fighting water tank 2. The four sides and the bottom of the water surrounding groove 11 are of a closed structure, and a detachable filter plate 12 is installed at the opening at the top. The water inlet end of the fire fighting water outlet pipeline 3 is located inside the water surrounding groove 11. Impurities in the fire fighting water tank 2 precipitate at the bottom, and the clean water at the top bypasses the water surrounding groove 11, passes through the filter plate 12, and then enters the fire fighting water outlet pipeline 3 to ensure the cleanliness of the water outlet.

[0035] Further, an overflow pipe 5 is also provided on the fire fighting water tank 2. The water inlet end of the overflow pipe 5 is located at the top of the inner cavity of the fire fighting water tank 2, and the water outlet end is located above the drainage trough 4.

[0036] Further, a ventilation opening 10 is provided at the top of the fire fighting water tank 2, and a rain-proof cap is installed above the ventilation opening 10.

[0037] The fire fighting pump room further includes a filtered water inlet pipeline 8, a filtered water outlet pipeline 7, a backwash drainage pipeline 6 and an intermediate pipeline 20.

[0038] The water inlet end of the filtered water inlet pipeline 8 is located at the bottom of the inner cavity of the fire fighting water tank 2, and the water outlet end is connected to the water inlet end of the filter 16, and is used for conveying water from the fire fighting water tank 2 to the filter 16. A first valve 14 is also installed on the filtered water inlet pipeline 8.

[0039] The water inlet end of the filter 16 is also connected to the water inlet end of the backwash drainage pipeline 6, and a second valve 15 is also provided on the backwash drainage pipeline 6. The water outlet end of the backwash drainage pipeline 6 is located above the drainage trough 4.

[0040] The water outlet end of the filter 16 is connected to the water inlet end of the filtered water outlet pipeline 7. The water outlet end of the filtered water outlet pipeline 7 is located at the top of the inner cavity of the fire fighting water tank 2 and is used for sending the filtered water back to the fire fighting water tank 2. A fifth valve 21 and a circulation pump 13 are sequentially arranged on the filtered water outlet pipeline 7 along the water flow direction. The advantage of arranging the circulation pump 13 on the filtered water outlet pipeline 7 is to ensure that the water passing through the circulation pump 13 is all filtered water, avoiding blockage of the circulation pump 13.

[0041] The water outlet end of the filter 16 is also connected to the water outlet end of the intermediate pipeline 20, and a third valve 17 is provided on the intermediate pipeline 20.

[0042] A main water pump 18, a tee joint and a fourth valve 19 are sequentially arranged on the fire fighting water outlet pipeline 3 along the water flow direction, and the tee joint is also connected to the water inlet end of the intermediate pipeline 20.

[0043] Maintenance personnel can regularly filter and clean the water in the fire fighting water tank 2 by operating the valves: open the first valve 14 and the fifth valve 21, keep the second valve 15 and the third valve 17 closed, start the circulation pump 13, pump the sewage at the bottom of the fire fighting water tank 2 into the filter 16, and the filtered water returns to the fire fighting water tank 2 along the filtered water outlet pipeline 7. After the filtration is completed, close the first valve 14 and the fifth valve 21. If it is considered that the filter 16 needs backwashing, open the second valve 15 and the third valve 17, start the main water pump 18, and use the clean water in the fire fighting water tank 2 to backwash the filter 16. Finally, close the second valve 15 and the third valve 17.

[0044] When water supply to the remote end is required, start the main water pump 18 and the fourth valve 19, and keep other valves closed.

[0045] It should be noted that for those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. The scope of the present utility model is defined by the claims rather than the above description.
