Description

Technical Field

[0001] This utility model relates to the technical field of fire pump connection components, and in particular to a modular prefabricated fire pump connection component. Background Technology

[0002] Fire pump connection assemblies are a collective term for a series of components used to connect fire pumps with other equipment or parts, enabling the fire pumps to function properly and form a complete fire water supply system. When using existing connection assemblies, as the number of connected devices increases, the main and auxiliary connection rings are unable to withstand large pressures and are prone to breakage. Therefore, a modular prefabricated fire pump connection assembly is needed.

[0003] Chinese patent provides a modular prefabricated fire pump connection assembly, publication number CN219413019U, which includes a connecting cylinder, a main connecting ring, a secondary connecting ring, a gasket inner ring, and fire-fighting pipes that are connected to each other. The fire-fighting pipes are respectively inserted into the two ends of the connecting cylinder. The surface of the fire-fighting pipes has a fixing groove. A sealing ring is fixedly connected to the inner wall of the connecting cylinder. The main connecting ring and the secondary connecting ring are respectively sleeved and connected to the surface of the fire-fighting pipes at both ends. The edge of the main connecting ring is provided with a rotatable fixing rod. The edge of the secondary connecting ring is provided with several fastening grooves. The gasket inner ring is fastened and connected to the surface of the fixing groove.

[0004] The aforementioned connecting components facilitate quick connection of fire-fighting pipelines, improving the convenience and stability of pipeline connections. They also enable more standardized and simpler operation. However, when using these components, multiple fixing rods are embedded into the interlocking grooves to connect the main and auxiliary connecting rings, thereby connecting and fixing the two fire-fighting pipes. As the number of connected devices increases, the main and auxiliary connecting rings cannot withstand the large pressure and are prone to breakage, thus affecting the normal use of the connecting components. Furthermore, the bolts are prone to over-tightening, damaging the sealing rings and causing leakage. Utility Model Content

[0005] The main objective of this invention is to provide a modular prefabricated fire pump connection assembly, which can effectively solve the technical problem in the background art where, as the number of connected devices increases, the main and auxiliary connection rings cannot withstand large pressure and are prone to breakage, thus affecting the normal use of the connection assembly.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A modular prefabricated fire pump connection assembly includes two connecting blocks. Valves are provided on the rear outer walls of the two connecting blocks. Sprinklers are fixedly installed on the rear end of the valves. Fire pipes are fixedly installed on the front end of the valves. One end of the fire pipes is rotatably connected to the inner wall of the connecting blocks. Two screws are provided on one outer wall of the fire pipes.

[0008] As a further embodiment of this utility model, a connecting shaft is fixedly installed on the front outer wall of each of the two connecting blocks, and a first arc-shaped fixing block is provided on the front side of the two connecting blocks. The outer wall of the first arc-shaped fixing block is slidably connected to the outer wall of the connecting shaft, and the outer wall of the first arc-shaped fixing block is threadedly connected to the screw.

[0009] As a further embodiment of this utility model, a second arc-shaped fixing block is provided on one side of the outer wall of the first arc-shaped fixing block, and the outer wall of the second arc-shaped fixing block is adaptively matched with the outer wall of the first arc-shaped fixing block. The outer wall of the second arc-shaped fixing block is slidably connected to the outer wall of the connecting shaft, and the outer wall of the second arc-shaped fixing block is threadedly connected to the screw.

[0010] As a further embodiment of this utility model, two first limiting blocks are fixedly installed on the rear outer wall of the right-side connecting block, and the outer wall of the first limiting block is threadedly connected to the outer wall of the screw.

[0011] As a further embodiment of this utility model, two second limiting blocks are fixedly installed on the rear outer wall of the left connecting block, and the outer wall of the second limiting block is threadedly connected to the outer wall of the screw, and the outer wall of the second limiting block is adaptively matched with the outer wall of the first limiting block.

[0012] As a further embodiment of this utility model, a placement groove is provided on one side of the outer wall of the fire-fighting pipe, and a sealing ring is provided on the inner wall of the placement groove, and the sealing ring is penetrated by a screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This modular prefabricated fire pump connection assembly, after placing two fire pipes on the inner wall of the connection block, closes the two connection blocks. During the closing process, the first limiting block can engage with the second limiting block. Then, the first and second arc-shaped fixing blocks are placed back on the connection shaft, and the screws are tightened to ensure a tight connection between the first and second arc-shaped fixing blocks and between the first and second limiting blocks. This allows the two connection blocks to quickly connect the fire pipes, with each part engaging with the other, making the whole assembly more robust, able to withstand greater pressure, easy to install and disassemble, greatly saving installation time and costs, and improving work efficiency.

[0015] 2) In this modular prefabricated fire pump connection assembly, the screw passes directly through the sealing ring during the tightening process. Since the sealing ring is placed in the placement groove, it can avoid damage to the sealing ring caused by over-tightening of the bolt, and effectively prevent leakage at the fire pipe connection.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1

[0023] Combination Figures 1-4 A modular prefabricated fire pump connection assembly includes two connection blocks 1, with valves 2 located on the rear outer walls of the two connection blocks 1, and nozzles 3 fixedly installed on the rear end of the valves 2.

[0024] See Figure 1 and Figure 2 Furthermore, a fire pipe 4 is fixedly installed at the front end of valve 2. One end of the fire pipe 4 is rotatably connected to the inner wall of connecting block 1. Two screws 5 are provided on one outer wall of the fire pipe 4. Connecting shafts 6 are fixedly installed on the front outer walls of both connecting blocks 1. A first arc-shaped fixing block 7 is provided on the front side of both connecting blocks 1. The outer wall of the first arc-shaped fixing block 7 is slidably connected to the outer wall of the connecting shaft 6. The outer wall of the first arc-shaped fixing block 7 is threadedly connected to the screws 5. A second arc-shaped fixing block 8 is provided on one outer wall of the first arc-shaped fixing block 7. The outer wall of the second arc-shaped fixing block 8 is adaptively matched to the outer wall of the first arc-shaped fixing block 7. The outer wall of the second arc-shaped fixing block 8 is slidably connected to the outer wall of the connecting shaft 6. The outer wall of the second arc-shaped fixing block 8 is threadedly connected to the screws 5.

[0025] Specifically, the fire pipe 4 can be rotated by the connecting block 1, the position of the nozzle 3 can be fixed by the valve 2, the position of the connecting shaft 6 can be fixed by the connecting block 1, the positions of the first arc-shaped fixing block 7 and the second arc-shaped fixing block 8 can slide by the connecting shaft 6, and the outer wall of the second arc-shaped fixing block 8 can be adapted to match the outer wall of the first arc-shaped fixing block 7, so that the first arc-shaped fixing block 7 can fit with the second arc-shaped fixing block 8.

[0026] Example 2

[0027] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, two first limiting blocks 9 are fixedly installed on the rear outer wall of the right connecting block 1, and the outer wall of the first limiting block 9 is threadedly connected to the outer wall of the screw 5. Two second limiting blocks 10 are fixedly installed on the rear outer wall of the left connecting block 1, and the outer wall of the second limiting block 10 is threadedly connected to the outer wall of the screw 5. The outer wall of the second limiting block 10 is adaptively matched with the outer wall of the first limiting block 9. A placement groove 11 is opened on one side of the outer wall of the fire pipe 4. A sealing ring 12 is provided on the inner wall of the placement groove 11, and the sealing ring 12 is penetrated by the screw 5.

[0028] Specifically, the positions of the two first limiting blocks 9 can be fixed by the connecting block 1 on the right side, and the positions of the two second limiting blocks 10 can be fixed by the connecting block 1 on the left side. The outer wall of the second limiting block 10 adapts to the outer wall of the first limiting block 9, so that the first limiting block 9 can fit with the second limiting block 10. The sealing ring 12 can be placed by the placement groove 11.

[0029] In actual operation, by removing the first arc-shaped fixing block 7 and the second arc-shaped fixing block 8 from the connecting shaft 6, the two connecting blocks 1 can be separated. After placing the two fire pipes 4 on the inner wall of the connecting block 1, the two connecting blocks 1 are closed. During the closing process, the first limiting block 9 can fit with the second limiting block 10. After placing the first arc-shaped fixing block 7 and the second arc-shaped fixing block 8 back onto the connecting shaft 6, by tightening the screw 5, the first arc-shaped fixing block 7 and the second arc-shaped fixing block 8 can be tightly connected, and the first limiting block 9 and the second limiting block 10 can be tightly connected. Thus, the two connecting blocks 1 can quickly connect the fire pipes 4. During the tightening process, the screw 5 will directly pass through the sealing ring 12. Since the sealing ring 12 is placed in the placement groove 11, it can avoid being over-tightened by the bolt 12.
