[0014] Beneficial effects of the present invention: 1. The fire pump set adopts a modular and prefabricated design. The modular unit components can be welded and assembled in the factory in advance. The construction site only needs to further assemble the welded and assembled unit components, which can significantly shorten the construction and installation period of the fire pump set. Moreover, the unit components can be inspected and debugged in the factory to detect the quality of each unit component itself. Subsequently, at the construction site, only the further assembly quality of each unit component needs to be tested, avoiding construction operations that require on-site replacement of accessories due to unqualified quality, thereby reducing the difficulty of on-site construction.

[0015] 2. The model is used to pre-simulate the construction and installation operations of the fire pump group to reduce the probability of errors in on-site installation, reduce material loss, and reduce the difficulty of construction. Moreover, in the model, only the fire pump room needs to be modeled separately. The pump unit, water collection pipe unit, and outlet pipe unit can all be modeled in advance based on the corresponding units already available in the factory. When simulating the installation of the fire pump group, only the three need to be assembled in the fire pump room, which effectively reduces the difficulty of modeling. In addition, the list of accessories for each unit structure can be entered into the computer in advance. After completing the simulated assembly, the computer can automatically generate a list of accessories required to assemble each unit structure, so that technicians can purchase accessories and assemble each unit structure.

The access end pipe valve 184 is a conventional pipeline valve, and the filter 185 is a Y-shaped filter. The filter 185 is used to filter impurities in the water body. The access end pressure detection gauge 183 is used to detect the water pressure before the water flows into the pump to ensure the safety of the pipeline.

[0028] In addition, since the length of the access main body 182 in this embodiment is relatively large, a support frame 186 is provided at the right end of the two access main bodies 182 in this embodiment to support the access main body 182, and the support frame 186 is just supported below the access end pipe valve 184.

The fire hydrant main pipe 31, the sprinkler main pipe 32, and the test water main pipe 33 are parallel to each other and are all mounted on the upper ends of the two water outlet pipe group support brackets 34.

[0031] To this end, technicians can fix the water outlet pipe group unit 3 above the pump group unit 1 by threading the lower ends of the two water outlet pipe group brackets to the upper end of the mounting bracket fixedly set on the base 111 mentioned in the above embodiment.

[0032] Also, see Figure 2The first outlet pipe 15 and the second outlet pipe 17 both include a pump outlet pipe body 192 and an outlet main pipe body 193.

The outlet main pipe body 193 of the first outlet pipe 15 is upwardly connected to the fire hydrant main pipe 31 to form a "T"-shaped three-way pipe structure with the fire hydrant main pipe 31. The outlet main pipe body 193 of the second outlet pipe 17 is upwardly connected to the sprinkler main pipe 32 to form a "T"-shaped three-way pipe structure with the sprinkler main pipe 32.

A water test valve 36 is also provided on the water test branch pipe 35 for technicians to perform water test inspections.

[0036] It should be added that: its participation Figure 5 A U-shaped channel steel structure for accommodating circuit lines and other pipelines for powering the pump is welded on the left side of the two water outlet pipe group support brackets 34.

[0037] See also Figure 6 The present invention also discloses a method for constructing and installing the assembled fire pump unit in any of the above embodiments, comprising the following installation steps: Step S1, constructing a model database; importing the existing three-dimensional model data of multiple groups of pump units of different sizes and models, multiple groups of water collection pipe units of different sizes and models, and multiple groups of water outlet pipe units of different sizes and models into the model database; Step S2, modeling and assembly: obtaining the fire pump room design drawings and constructing a three-dimensional model of the fire pump room; According to the fire pump group installation and construction requirements and in combination with the fire pump room pipeline layout design drawings, the pump group unit model, the manifold group unit model, and the outlet pipe group unit model in the model database are called into the fire pump room model, and a simulated installation is performed; During the simulation installation process, if there is interference between a unit model and the fire pump room model, import a corresponding unit model with a relatively smaller size to replace it until there is no interference between the corresponding unit model and the fire pump room model; If interference still exists after replacing the corresponding unit model of the smallest size model, based on the corresponding unit model of the smallest size model, further replace the corresponding component parts that interfere with the corresponding unit model of the smallest size model and the fire pump room model until there is no interference; Step S3, generating a parts list; based on the three-dimensional model of the fire pump room containing one or more assembled fire pump groups, generating its planar structure diagram, and sequentially generating a parts list of the pump group unit, a parts list of the manifold unit, and a parts list of the outlet pipe group, wherein the parts list includes the name, size, model, and quantity information of the parts; If an accessory is replaced in step S2, the name, size, model, and quantity information of the replaced accessory are used to correspond to the name, size, model, and quantity information of the replaced accessory in the replacement accessory list to correct the accessory list information; Step S4, on-site installation; if no parts are replaced in step S2, the physical unit structure corresponding to the unit model used in the simulated assembly is directly inspected and debugged, and the physical unit structure that passes the inspection and debugging is transported to the construction site for welding and assembly; if the existing physical unit structure is insufficient, the parts are purchased according to the parts list and assembled into the corresponding physical unit structure in the factory for factory inspection and debugging and on-site construction and installation; If there is a replacement of parts in step S2, the parts are selected based on the revised parts list and assembled into a new corresponding physical unit structure in the factory for factory inspection and commissioning and on-site construction and installation.

[0038] Among them, all the models in the model database in step S1 can be obtained by technicians after disassembling fire pump groups of various sizes known on the market; moreover, every time a new physical unit that is not in the original model database is assembled in the factory, technicians can also construct a three-dimensional model of the physical unit and import it into the model database.

[0039] In addition, because the components of each fire pump group are basically the same, but there are differences in size, when it is found that the corresponding unit model with the smallest model size in the model database still interferes with the fire pump room model, the technicians can simply replace the accessories of the corresponding unit model in the interference area with smaller accessories of the same name, without having to rebuild a new corresponding unit model.

[0040] The so-called “interference” in steps S2 and S3 can be understood as the size of the corresponding unit model exceeding the capacity limit of the fire pump room.

[0041] Any matters not mentioned above are applicable to the prior art.

[0042] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
