Description

Technical Field

[0001] This application relates to the field of fire protection technology, and in particular to a fire pump room. Background Technology

[0002] As the core equipment room of a building's fire protection water supply system, the passage capacity of the internal safety passages in a fire pump room directly affects personnel evacuation, fire rescue, and emergency equipment operation during a fire. According to national fire protection technical standards such as the "Code for Fire Protection Design of Buildings" (GB50016) and the "Technical Code for Fire Water Supply and Fire Hydrant Systems" (GB50974), the net width of the main safety passages in a fire pump room should not be less than 1.2 meters. This minimum width limit is a mandatory requirement, designed to ensure normal passage for inspection and maintenance personnel, rapid evacuation during a fire, and smooth entry for rescue personnel carrying equipment. It also meets the space requirements for the installation, dismantling, and maintenance of pump units, preventing congestion, obstruction, or inconvenience in equipment maintenance caused by excessively narrow passages, thereby ensuring the reliable operation of the fire protection system in emergencies such as fires.

[0003] Existing fire pump rooms typically place safety passages between the fire pumps and the walls, with the pump's water delivery direction perpendicular to the wall. Furthermore, valves, pipes, and multiple connectors must be connected in series along this direction, resulting in a significant length occupied by fire protection components in that direction. During fire protection engineering construction, insufficient pre-planning and subsequent expansion of the fire protection system leading to larger equipment selections often result in inadequate pre-planned dimensions for the pump room. After the pumps, pipes, connectors, and valves are installed, the safety passage space is easily encroached upon, leading to narrow passages. Summary of the Invention

[0016] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

It should be understood that the terms "first," "second," etc., are used in this application to describe various information, but this information should not be limited to these terms, and these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0018] like Figure 1 , Figure 2 As shown, the fire pump room of this application includes a pump room body 1, a water supply pipe 2, and a water pump 3. The pump room body 1 has a first direction X and an internal space. The pump room body 1 includes a first wall 11. The water supply pipe 2 and the water pump 3 are arranged in the internal space. In the first direction X, the water pump 3 is located between the water supply pipe 2 and the first wall 11. The water supply pipe 2 is connected to one end of the water pump 3. The first wall 11 and the water pump 3 are arranged at intervals, and a safety passage 12 is formed between the water pump 3 and the first wall 11. The water pump 3 has a water supply direction, which is arranged at an angle to the first direction X. Arranging the water pump 3 along the first direction X relative to the water supply direction can reduce the projected length of the water pump 3 in the first direction X, thereby making the width of the safety passage 12 wider.

[0019] In some embodiments of this application, the fire pump room further includes a bend joint 4. The axis of the water supply pipe 2 is arranged along a first direction X. In the first direction X, one end of the bend joint 4 is connected to the water supply pipe 2, and the other end is connected to the end of the water pump 3 away from the first wall 11. Specifically, the pump room body 1 also has a second direction Y, which is perpendicular to the first direction X. The pump room body 1 also includes a second wall 13, a third wall 14, and a fourth wall 15. In the first direction X, the first wall 11 and the second wall 13 are arranged relatively alternately. In the second direction Y, the third wall 14 and the fourth wall 15 are arranged relatively alternately. The first wall 11, the third wall 14, the second wall 13, and the fourth wall 15 are connected in series to form an internal space. A doorway 141 is provided on the third wall 14 or the fourth wall 15. In the second direction Y, the doorway 141 is arranged opposite to the safety passage 12. A fire water tank is provided on the outside of the fire pump room. In the first direction X, the fire water tank is adjacent to the second wall 13. The end of the water supply pipe 2 away from the water pump 3 needs to pass through the second wall 13 to enter the fire water tank. The axis of the water supply pipe 2 is arranged along the first direction X, which allows the water supply pipe 2 to pass perpendicularly through the second wall 13, facilitating the installation of the water supply pipe 2 in the second wall 13.

[0020] In some embodiments of this application, the pump house body 1 also includes a ground, and the fire pump house also includes a support frame 5 fixed to the ground, with the elbow joint 4 connected to the support frame 5. During the operation of the water pump 3, the water flow will turn within the elbow joint 4, and the elbow joint 4 will be impacted by the water flow when it passes through it. By connecting the elbow joint 4 to the support frame 5, the support frame 5 can reduce some of the vibration caused by the impact, prevent the connection between the elbow joint 4 and the water supply pipe 2 and between the elbow joint 4 and the water pump 3 from becoming loose, and improve the reliability of the fire protection system operation.

[0021] In some embodiments of this application, the water supply pipe fitting 2 includes a first pipe assembly 21 and a Y-type filter 22. In the first direction X, the first pipe assembly 21, the Y-type filter 22, and the elbow joint 4 are connected sequentially. The support frame 5 is connected to the end of the elbow joint 4 closest to the water pump 3. Specifically, the inlet end of the Y-type filter 22 is connected to the first pipe assembly 21, and the outlet end of the Y-type filter 22 is connected to the end of the elbow joint 4 away from the water pump 3. The Y-type filter 22 can filter the water flow drawn into the water pump 3, intercepting and removing impurities from the water. When maintaining the Y-type filter 22, simply open its bottom end cap to clean or replace the filter screen, facilitating maintenance.

[0022] In this embodiment, to facilitate the removal of the filter screen of the Y-type filter 22, the lowest point of the Y-type filter 22 is higher than the ground, and the distance between the lowest point of the Y-type filter 22 and the ground is greater than or equal to 100mm. Furthermore, the support frame 5 is connected to the elbow joint 4 near the water pump 3. This arrangement allows for a larger gap between the support frame 5 and the Y-type filter 22, facilitating filter screen replacement.

[0023] In some embodiments of this application, the fire pump room further includes a first flexible joint 61; in the first direction X, the bend joint 4, the first flexible joint 61, and the water pump 3 are connected in sequence. Specifically, one end of the first flexible joint 61 is connected to the end of the bend joint 4 opposite to the first pipe assembly 21, and the other end of the first flexible joint 61 is connected to the inlet of the water pump 3. The water pump 3 will generate vibration during operation; the flexible joint can absorb the vibration and prevent it from being transmitted to the pipes connected to it, thereby reducing the risk of loosening of pipe joints due to vibration.

[0024] In some embodiments of this application, the bend joint 4 is an arc-shaped joint. The arc-shaped joint allows the water flow to be smoother when passing through the bend joint 4. The arc-shaped joint has a central axis, and the shape of the central axis is an arc.

[0025] In some embodiments of this application, the fire pump room further includes a reducing joint 7, one end of which is connected to a bend joint 4, and the other end is connected to the water pump 3. Specifically, the reducing joint 7 is an eccentric reducer, with its top horizontally aligned with the top of the water inlet of the water pump 3, and its bottom inclined vertically, with its higher end aligned with the bottom of the water inlet of the water pump 3. This arrangement prevents air accumulation at the suction inlet of the water pump 3, improving the water suction efficiency of the water pump 3.

[0026] In some embodiments of this application, the fire pump room further includes a water outlet pipe fitting 8 and a rising stem gate valve 9. The water outlet pipe fitting 8 is connected to the end of the water pump 3 near the first wall 11 and extends upwards, forming a safety passage 12 between the water outlet pipe fitting 8 and the first wall 11. The rising stem gate valve 9 is connected to the water outlet pipe fitting 8 and is located outside the safety passage 12. Specifically, in the prior art, the rising stem gate valve 9 on the water outlet pipe fitting 8 is often installed facing the safety passage 12, which causes the rising stem gate valve 9 to encroach on the space of the safety passage 12. In this application, the rising stem gate valve 9 is located outside the safety passage 12, which can further increase the width of the safety passage 12.

[0027] In some embodiments of this application, the fire pump room further includes a second flexible joint 62. One end of the second flexible joint 62 is connected to the end of the pump 3 away from the water supply pipe 2, and the other end is connected to the outlet pipe 8. The second flexible joint 62 can prevent vibration from being transmitted to the outlet pipe 8, which extends upward to the fire protection pipe network at the top of the pump room body 1.

[0028] In some embodiments of this application, a water collection trough 16 is provided at the bottom of the fire water tank, and the trough is arranged close to the second wall 13. One end of the water supply pipe 2 extends into the fire water tank and downwards into the water collection trough 16. Furthermore, one end of the water supply pipe 2 located in the water collection trough 16 is connected to a vortex preventer 23. The vortex preventer 23 can prevent the water supply pipe 2 from generating vortices when drawing water and prevent air from being drawn into the water pump 3, thereby ensuring the safe and reliable operation of the fire water supply system.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] In summary, the fire pump room of this application includes a pump room body 1, a water supply pipe fitting 2, and a water pump 3. The pump room body 1 has a first direction X and an internal space. The pump room body 1 includes a first wall 11. The water supply pipe fitting 2 and the water pump 3 are arranged in the internal space. In the first direction X, the water pump 3 is located between the water supply pipe fitting 2 and the first wall 11. The water supply pipe fitting 2 is connected to one end of the water pump 3. The first wall 11 and the water pump 3 are arranged at intervals, and a safety passage 12 is formed between the water pump 3 and the first wall 11. The water pump 3 has a water supply direction, which is arranged at an angle to the first direction X. Arranging the water pump 3 along the first direction X relative to the water supply direction can reduce the projected length of the water pump 3 in the first direction X, thereby making the width of the safety passage 12 wider.

[0031] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
