A fire pump connection

Abstract

This utility model discloses a fire pump coupling. This coupling aims to solve the technical problem that in existing technologies, the screw is often exposed, making it susceptible to corrosion and rust, and difficult to control valve opening and closing during emergency use. It includes a coupling body, with a screw rotatably connected to the top of the body. A rotating wheel is mounted on the top of the screw, and a sleeve is threadedly connected to the top of the screw. A hexagonal block is fixedly connected to the top of the sleeve, and the rotating wheel is mounted on the hexagonal block. A flexible protective component is provided on the outside of the screw. The flexible protective component includes a flange mounted on the top of the coupling body, a connecting pipe mounted on the side wall of the sleeve, and a rubber telescopic tube fixedly connected to the top end face of the flange. This utility model utilizes the rubber telescopic tube to seal and protect the exposed part of the screw, making it difficult for rainwater, dust, and impurities to contact the screw surface, thus increasing the screw's service life and durability.

Description

Technical Field

[0001] This utility model belongs to the field of fire protection facilities technology, and specifically relates to a fire pump connection. Background Technology

[0002] Fire pump connections are important emergency water supply devices in building fire protection systems. They are mainly used to supplement the indoor fire protection pipe network with water from external sources (such as fire trucks) when the indoor fire pump fails to supply water normally or the amount of water needed for fire fighting is insufficient, thereby ensuring the continuous water supply needs for fire fighting and rescue.

[0003] However, current fire pump connections are generally located outdoors, and the screws controlling the valve core inside the connection are often exposed. They are easily corroded by natural elements (such as rainwater, acid rain, soil, and acidic substances) and rust easily. In emergency use, it is difficult to control the opening and closing of the valve, resulting in poor practicality.

[0004] Therefore, a fire pump connection was designed to overcome the aforementioned technical deficiencies. Utility Model Content

This fire pump connection device aims to solve the technical problem that the screw is often exposed in the existing technology, which is prone to rust due to natural corrosion, and it is difficult to control the opening and closing of the valve during emergency use.

[0006] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a fire pump connector, including a connector body, a screw rotatably connected to the top of the connector body, a rotating wheel assembled at the top of the screw, a sleeve threadedly connected to the top of the screw, a hexagonal block fixedly connected to the top of the sleeve, and the rotating wheel assembled on the hexagonal block.

[0008] Furthermore, the limiting component includes pin holes formed in the flange and the screw sidewall, and a cotter pin is inserted into the pin holes.

[0009] Furthermore, a collar is rotatably connected to the bottom end of the connecting pipe, and the top end of the rubber telescopic pipe is fixedly connected to the collar.

[0010] Furthermore, a positioning plate is fixedly connected to the side wall of the sleeve, and the top end of the connecting pipe abuts against the positioning plate.

[0011] Furthermore, the connecting pipe and the sleeve are connected by threads.

[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the design of cleaning and limiting components, utilizes a rubber telescopic tube to seal and protect the exposed part of the screw, making it difficult for external rainwater, dust, and impurities to come into contact with the screw surface, thereby increasing the screw's service life and durability.

[0015] This specific embodiment is a fire pump connection, the structural diagram of which is shown below. Figures 1-7 As shown, it includes a connector body 1, a screw 2 rotatably connected to the top of the connector body 1, a rotating wheel 3 mounted on the top of the screw 2, a sleeve 5 threadedly connected to the top of the screw 2, a hexagonal block 4 fixedly connected to the top of the sleeve 5, and the rotating wheel 3 mounted on the hexagonal block 4. A flexible protective component is provided on the outside of the screw 2.

[0016] like Figure 3 and Figure 6As shown, the flexible protection component includes a flange 6 mounted on the top of the connector body 1, a connecting pipe 7 mounted on the side wall of the sleeve 5, a rubber telescopic pipe 8 fixedly connected to the top end face of the flange 6, the top end of the rubber telescopic pipe 8 being rotatably connected to the connecting pipe 7, and a limit component provided on the side wall of the flange 6.

[0017] like Figure 6 As shown, a collar 9 is rotatably connected to the bottom end of the connecting pipe 7, and the top end of the rubber telescopic pipe 8 is fixedly connected to the collar 9.

[0018] The rubber telescopic tube 8 has a wavy cross-section and is made of rubber, which has good elasticity and corrosion resistance. It can effectively isolate various impurities in nature, such as rainwater and dust. For example, in rainy weather, rainwater can easily wash away the lubricating oil on the surface of the screw 2, which can cause the screw 2 to rust. By setting the rubber telescopic tube 8, the contact between rainwater and the screw 2 can be effectively isolated, providing good protection.

[0019] Furthermore, since the rubber telescopic tube 8 and the connecting tube 7 are rotatably connected by the collar 9, rotating the wheel 3 will not cause the rubber telescopic tube 8 to rotate, thus keeping the rubber telescopic tube 8 in a stable state.

[0020] like Figure 3 and Figure 7 As shown, the limiting assembly includes a pin hole 11 formed in the side wall of the flange 6 and the screw 2, and the same cotter pin 12 is inserted into the pin hole 11.

[0021] To further ensure the stability of the connector under normal conditions, after the flange 6 is installed, the cotter pin 12 is inserted into the pin hole 11 to lock the screw 2, preventing children from accidentally turning the wheel 3 and opening the valve, thereby improving its stability and practicality.

[0022] like Figure 4 and Figure 5 As shown, a positioning plate 10 is fixedly connected to the side wall of the sleeve 5, and the top end of the connecting pipe 7 abuts against the positioning plate 10. This serves both as a limiting function and as a sealing function when the connecting pipe 7 abuts against the positioning plate 10.

[0023] like Figure 4 and Figure 6 As shown, the connecting pipe 7 and the sleeve 5 are connected by a thread. Furthermore, the threaded connection between the connecting pipe 7 and the sleeve 5 allows maintenance personnel to periodically open the rubber telescopic tube 8 to check the lubrication status of the screw 2.

[0024] Working principle: When in use, the operator needs to first remove the cotter pin 12 to release the screw 2 from the fixation, and then rotate the rotating wheel 3 to drive the screw 2 to rotate, thereby controlling the opening or closing of the valve; During long-term use, the rubber telescopic tube 8 can effectively protect the screw 2, preventing external impurities from contacting the screw 2, thereby extending the service life of the screw 2.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
