Description

Technical Field

[0001] This utility model belongs to the field of fire pump connection technology, and in particular relates to a ground-mounted protective fire pump connection device. Background Technology

[0002] Fire pump connections are an important component of fire protection systems. They connect external water sources to the fire pump system to ensure sufficient water supply for fire suppression in the event of a fire. A fire pump connection is typically a standardized interface used by firefighters at the fire scene to connect to fire pumps or the municipal water supply system.

[0003] A ground-mounted protective fire pump connection (announcement number: CN222018858U) disclosed in the public notice includes a pump connection body. The outside of the pump connection body is covered by a push-pull movable protective box for protection. Inside the protective box, a collision protection frame is installed around the outside of the pump connection body to provide impact protection. This utility model achieves the effects of protecting the pump connection and extending its service life; it also facilitates use and subsequent maintenance and repair.

[0004] The aforementioned patent achieves protection for the water pump connector and extends its service life through the cooperation of components such as the main body of the water pump connector and the push-pull movable protective box. It also facilitates use and subsequent maintenance and repair. However, it cannot achieve the effect of quick installation and disassembly of fire water pipes. It solves the problems of excessive connection time and cumbersome connection of traditional threaded connections, which delays the speed of fire emergency response. Therefore, we propose a ground-mounted protective fire pump connector. Utility Model Content

[0005] The purpose of this utility model is to provide a ground-mounted protective fire pump connector, which solves the problems of excessively long and cumbersome connection time and delayed emergency response speed of traditional threaded connections through a quick connection device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a ground-mounted protective fire pump connector, including a base, a fire hydrant fixedly connected to the top of the base, a valve body provided on the top of the fire hydrant, a water outlet pipe fixedly connected to the circumference of the fire hydrant, a connector fixedly connected to one end of the water outlet pipe, a connecting end fixedly connected to one end of the connector, and a quick-connect device provided on the connecting end.

[0008] The quick-connect device includes a placement groove formed on the circumferential surface of the connecting end. A cylindrical groove is formed on the side of the connecting end. A water pipe connecting block is slidably connected to the inner side of the placement groove. A groove is formed on the side of the water pipe connecting block, and a compression spring is fixedly connected to the inner side of the groove. One end of the compression spring is fixedly connected to a locking pin. The main function of this quick-connect device is to achieve a quick and stable connection between water pipes and other equipment through the cooperation of the water pipe connecting block, groove, compression spring, and locking pin. This allows firefighters to quickly connect water pipes to fire hydrants, shortening connection time and increasing the success rate of rescue operations.

[0009] Furthermore, a pressing rod is slidably connected to the inner side of the cylindrical groove, and the inner side of the cylindrical groove is located on the displacement trajectory of the locking post. This design allows the water pipe connector to be connected and disconnected quickly and safely, and the operation is simple; the connection and disassembly can be completed simply by pressing the pressing rod, improving the convenience and efficiency of use.

[0010] Furthermore, one end of the locking pin is located on the displacement trajectory of the pressing rod, and the diameter of the locking pin is the same as the diameter of the cylindrical groove. This design avoids unnecessary gaps in the cylindrical groove, thus ensuring the stability and tightness of the quick-connect device. The matching diameter of the locking pin and the cylindrical groove ensures a secure lock on the water pipe connector and prevents the locking pin from getting stuck or unable to move smoothly due to mismatch.

[0011] Furthermore, a guide groove is provided on the inner side of the placement slot, and the inner side of the guide groove is slidably connected to the circumferential surface of the locking pin. A water pipe is fixedly connected to one end of the water pipe connecting block. These designs achieve precise positioning, secure connection, and easy operation of the water pipe connection. The guide groove mainly controls the movement trajectory of the locking pin, ensuring its smooth operation, while the fixed connection between the water pipe connecting block and the water pipe guarantees the stability and reliability of the water pipe.

[0012] Furthermore, a limiting and fixing device is provided on the side of the connecting end. This device includes a groove formed on the side of the connecting end. A limiting arc-shaped fixing plate is slidably connected to the inner side of the groove. A connecting rope is fixedly connected to the circumferential surface of the connecting end, and a pin is fixedly connected to one end of the connecting rope. A pin groove is formed on the side of the limiting arc-shaped fixing plate, and the circumferential surface of the pin is slidably connected to the inner side of the pin groove. This design further secures the water pipe connecting block, preventing it from being washed away by water pressure.

[0013] Furthermore, the diameter of the pin matches the diameter of the slot. This design optimizes the fit between the pin and the slot, ensuring a secure, safe, and easy connection.

[0014] Furthermore, the arc-shaped surface of the limiting arc-shaped fixing plate fits into the circumferential surface of the water pipe connecting block. This design makes the connecting components more stable and reliable, and performs excellently under high load and vibration environments, ensuring the efficient and safe operation of the water pipe system.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model enables the rapid installation and disassembly of fire water pipes by setting up a quick connection device. The device uses a spring-driven locking post that engages with a cylindrical groove for locking. Simply insert the water pipe connection block into the placement groove to automatically lock it in place. When disassembling, press the pressing rod to release it. Compared with the traditional threaded connection method, it significantly shortens the connection time and improves the speed of fire emergency response. It is especially suitable for emergency water supply scenarios in fire scenes.

[0017] 2. This utility model provides double protection by adding a limiting and fixing device to ensure connection stability under high water pressure. Based on the quick connection, a secondary fixation is achieved by sliding a limiting arc-shaped fixing plate and inserting a pin, effectively preventing the risk of water pipe detachment due to water pressure impact. This structure is simple, reliable, and easy to operate, further enhancing the safety of firefighting operations.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The main function of this quick-connect device 7 is to achieve a quick and stable connection between the water pipe 9 and other equipment through the cooperation of the water pipe connecting block 8, the groove 73, the compression spring 74, and the locking post 75. This allows firefighters to quickly connect the water pipe 9 to the fire hydrant 2, shortening the connection time and improving the success rate of rescue.

[0030] A pressing rod 76 is slidably connected to the inner side of the cylindrical groove 72, and the inner side of the cylindrical groove 72 is located on the displacement trajectory of the locking post 75. This design allows the water pipe connecting block 8 to be connected and disconnected quickly and safely, and the operation is simple. The connection and disassembly can be completed by simply pressing the pressing rod 76, which improves the convenience and efficiency of use.

[0031] One end of the locking pin 75 is located on the displacement trajectory of the pressing rod 76, and the diameter of the locking pin 75 is the same as the diameter of the cylindrical groove 72. This design avoids unnecessary gaps in the cylindrical groove 72 caused by the locking pin 75, thus ensuring the stability and tightness of the quick-connect device 7.
