Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, and more specifically, to a novel fire pump connection. Background Technology

[0002] Fire pump connection is a core connection device in fire water supply system. It is used to temporarily connect external fire water sources (such as fire trucks and motorized pumps) to the internal fire pipe network of a building during a fire, so as to supply water to the fire protection system of the building through external pressure, supplementing or replacing the water supply capacity of the fire pumps inside the building.

[0003] A search revealed Chinese patent application CN221412102U, which discloses a fire pump connection, including a connection body with a protective box outside the body. The protective box has several fixed posts on its inner wall, and each fixed post has a groove. A damper is installed in the groove, and a spring is installed on the damper. One end of the damper is connected to a push plate, and a push rod is installed on the push plate. This invention, by installing a spring, prevents the fire pump connection from directly impacting the connection when it is struck. Instead, the impacting object strikes the push rod. When the push rod is impacted, it is compressed against the damper via the push plate, and the spring is also compressed and undergoes elastic deformation. When the external force disappears, the spring returns to its original shape, causing the push plate to return the push rod to its original shape. This protects the fire pump connection from damage upon impact and extends its service life. However, the following shortcomings still exist in use: Although the protective box in the above patent can protect the connector, in order to facilitate the later connection of the interface pipe to the water pipe, part of the connector structure is left unprotected, making the upper structure of the connector still susceptible to damage from impact. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of fire pump connection to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A novel fire pump coupling includes: a coupling body; A connecting pipe disposed on the side end of the connector body; An operating component is fixedly connected between the connector body and the connecting pipe; the operating component includes a filter part fixedly connected to the outer wall of the connecting pipe, the filter part is connected to a mounting part, and a protective part is provided on the side of the mounting part. The filter section includes a connecting threaded groove formed on the outer wall of the connecting pipe, a connecting pipe is threadedly connected to the inner surface of the connecting threaded groove, an inner pipe is fixedly connected to the inner surface of the outer end of the connecting pipe, and a filter screen is fixedly connected to the inner surface of the inner pipe.

[0006] As a preferred technical solution of this application, the mounting part includes a closed cover that snaps onto the inner surface of the outer end of the connecting pipe. A limiting frame is fixedly connected to the left side of the closed cover. An installation rod is snapped onto the inner surface of the left end of the limiting frame. The left end of the installation rod is snapped onto the inner surface of the mounting groove. The mounting groove is opened on the side of the extension ring. The inner wall of the extension ring is fixedly connected to the outer wall of the connecting pipe. An extension block is fixedly connected to the outer wall of the left end of the installation rod. The outer surface of the extension block is snapped onto the inner surface of the annular groove. The annular groove is opened on the inner surface of the mounting groove. A movable groove is opened on the right side of the extension block. A reinforcing block is fixedly connected to the inner surface of the movable groove by a spring. The outer end of the reinforcing block passes through the movable groove and is snapped onto the inner surface of the reinforcing groove. The reinforcing groove is opened on the right side of the inner surface of the annular groove.

[0007] As a preferred technical solution of this application, the protective part includes a fixed base that is snapped onto the outer wall of the bottom end of the connector body. A fixed rod is fixedly connected to the top of the fixed base. An annular block is sleeved on the outer wall of the fixed rod. A protective rod is fixedly connected to the outer wall of the annular block. A sliding groove is formed on the outer wall of the protective rod. A T-shaped slider is slidably connected to the inner surface of the sliding groove. A second spring plate is hinged to the outer end of the T-shaped slider. A movable rod is fixedly connected to the inner surface of the second spring plate. The end of the movable rod away from the second spring plate slides through the outer wall of the annular block and the fixed rod. A buffer spring is fixedly connected to the inner surface of the second spring plate. The other end of the buffer spring is fixedly connected to the outer wall of the annular block. A first spring plate is fixedly connected to the outer wall of the side end of the second spring plate.

[0008] As a preferred technical solution of this application, the number of filter screens is set to two, and the two filter screens are respectively snapped onto the inner surface of the two-sided connecting pipes. No matter which side the external water source enters from, impurities can be intercepted, avoiding the entry of impurities from the other side due to filtration on one side, and preventing impurities from entering the water pump or fire protection pipe network.

[0009] As a preferred technical solution of this application, the inner surface of the limiting frame and the outer wall of the mounting rod are configured to slide together to ensure the movement direction of the mounting rod.

[0010] As a preferred technical solution of this application, the two ends of the first spring plate are respectively fixedly connected between the side ends of the two second spring plates. When one side is impacted, the impact force can be transmitted to the other side through the first spring plate, so that the buffer springs on both sides are compressed synchronously, avoiding structural deformation caused by excessive force on one side.

[0011] As a preferred technical solution of this application, the inner ring of the buffer spring is movably sleeved on the outer wall of the movable rod, and the movable rod plays a guiding role for the buffer spring to prevent the buffer spring from shifting during the extension and contraction process.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. With the filter section, the connecting pipe and the coupling pipe are connected by threads. They can be manually rotated and disassembled without tools to remove the filter screen from the inner pipe for cleaning or replacement. At the same time, the threaded connection between the connecting pipe and the coupling pipe has a tighter sealing surface, which can prevent the filter screen from shifting or deforming due to water flow impact, ensuring a continuous and stable filtration effect.

[0013] 2. The sealing cover is secured inside the connecting pipe by the installation part, and the installation rod is controlled to move the extension block into the movable part. When the extension block and the annular block are aligned, the installation rod is rotated 180° so that the extension block moves the reinforcing block to correspond to the reinforcing groove. The spring force is used to move the reinforcing block and engage it in the reinforcing groove, thus completing the installation of the sealing cover. This can effectively prevent the sealing cover from loosening due to vibration, such as vehicle collision or water flow impact.

[0014] 3. Through the set protective part, the T-shaped slider slides in the groove, so that the angle of the protective rod can be adjusted according to the impact direction, expanding the protective coverage area. The sliding connection between the movable rod and the ring block and the fixed rod further enhances the flexibility of the protective structure and adapts to impacts of different forces. The inner ring of the buffer spring is fitted with a movable rod, which not only ensures the stability of the buffer spring's extension and contraction direction, but also strengthens the protective rod's resistance to deformation through the supporting effect of the movable rod, thus extending the service life of the components.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0018] like Figure 1-8 As shown, the novel fire pump connector proposed in this embodiment includes: connector body 1; Connecting pipe 2 is provided at the side end of connector body 1; An operating component 3 is fixedly connected between the connector body 1 and the connecting pipe 2; the operating component 3 includes a filter part 31 fixedly connected to the outer wall of the connecting pipe 2, the filter part 31 is connected to a mounting part 32, and a protective part 34 is provided on the side of the mounting part 32. The filter section 31 includes a connecting threaded groove 311 formed on the outer wall of the connecting pipe 2. A connecting pipe 312 is threadedly connected to the inner surface of the connecting threaded groove 311. An inner pipe 313 is fixedly connected to the inner surface of the outer end of the connecting pipe 312. A filter screen 314 is fixedly connected to the inner surface of the inner pipe 313. Preferably, there are two filter screens 314, which are respectively snapped onto the inner surfaces of the two connecting pipes 2 on both sides. Regardless of which side the external water source enters from, impurities can be intercepted, preventing impurities from entering the other side due to filtration on one side, and preventing impurities from entering the water pump or fire protection pipeline network.

[0019] In this embodiment, like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the mounting part 32 includes a sealing cover 321 that snaps onto the inner surface of the outer end of the connecting pipe 312. A limit bracket 322 is fixedly connected to the left side of the sealing cover 321. A mounting rod 323 is snapped onto the inner surface of the left end of the limit bracket 322. The left end of the mounting rod 323 is snapped onto the inner surface of the mounting groove 325, which is located on the side of the extension ring 326. The inner wall of the extension ring 326 is fixedly connected to the outer wall of the connecting pipe 2. An extension rod 323 is fixedly connected to the outer wall of the left end of the mounting rod 323. The extension block 324 has its outer surface engaged with the inner surface of the annular groove 327, which is located on the inner surface of the mounting groove 325. A movable groove 328 is located on the right side of the extension block 324. A reinforcing block 330 is fixedly connected to the inner surface of the movable groove 328 via a spring 329. The outer end of the reinforcing block 330 passes through the movable groove 328 and engages with the inner surface of the reinforcing groove 331, which is located on the right side of the inner surface of the annular groove 327. In the actual product, the inner surface of the limiting bracket 322 and the outer wall of the mounting rod 323 are slidably connected to ensure the direction of movement of the mounting rod 323.

[0020] like Figures 1 to 3 As shown, the protective part 34 includes a fixed base 341 that is snapped onto the outer wall of the bottom end of the connector body 1. A fixed rod 342 is fixedly connected to the top of the fixed base 341. An annular block 343 is sleeved on the outer wall of the fixed rod 342. A protective rod 344 is fixedly connected to the outer wall of the annular block 343. A groove 345 is opened on the outer wall of the protective rod 344. A T-shaped slider 346 is slidably connected to the inner surface of the groove 345. A second spring plate 347 is hinged to the outer end of the T-shaped slider 346. A movable rod 348 is fixedly connected to the inner surface of the second spring plate 347. One end of the movable rod 348 away from the second spring plate 347 slides through the outer wall of the annular block 343 and the fixed rod 342. A buffer spring 349 is fixedly connected to the inner surface of the second spring plate 347. The other end of the buffer spring 349 is fixedly connected to the outer wall of the annular block 343. A first spring plate 340 is fixedly connected to the outer wall of the side end of the second spring plate 347.

[0021] in, The two ends of the first spring plate 340 are fixedly connected between the side ends of the two second spring plates 347 respectively. The first spring plate 340 connects the two second spring plates 347 into a whole. When one side is impacted, the impact force can be transmitted to the other side through the first spring plate 340, so that the buffer springs 349 on both sides are compressed synchronously, avoiding structural deformation caused by excessive force on one side.

[0022] The inner ring of the buffer spring 349 is movably sleeved on the outer wall of the movable rod 348. The movable rod 348 guides the buffer spring 349 to prevent it from shifting during extension and retraction, and uses the elastic force of the buffer spring 349 to drive the second spring plate 347 to reset after the movable rod 349 is subjected to force.

[0023] When using this new type of fire pump connector: Align the connecting pipe 312 with the connecting thread groove 311 on the outer wall of the connecting pipe 2, and rotate the connecting pipe 312 until it is tightened. At the same time, the connecting pipe 312 drives the filter screen 314 to be installed on the inner surface of the connecting pipe 2 through the inner pipe 313. With the filter screen 314 in the connecting pipes 2 on both sides, impurities can be intercepted no matter which side the external water source enters from, avoiding the entry of impurities from the other side due to filtration on one side, and preventing impurities from entering the water pump or fire pipeline network. At the same time, the tighter sealing surface of the threaded connection between the connecting pipe 312 and the connecting pipe 2 can prevent the filter screen 314 from shifting or deforming due to water flow impact, ensuring a continuous and stable filtration effect, and can be manually rotated and disassembled without tools.

[0024] Insert the sealing cap 321 into the inner surface of the outer end of the connecting pipe 312. Align the left end of the mounting rod 323 with the mounting groove 325 of the extension ring 326 and press the mounting rod 323 inward so that the extension block 324 is finally inserted into the annular groove 327. At this time, rotate the mounting rod 323 180° so that the extension block 324 drives the reinforcing block 330 to correspond to the reinforcing groove 331. Use the elastic force of the spring 329 to drive the reinforcing block 330 to move and engage in the reinforcing groove 331, thus completing the installation of the sealing cap 321. This can effectively prevent loosening due to vibration. Conversely, control the mounting rod 323 in the opposite direction to drive the extension block 324 to rotate synchronously 180°. At this time, the reinforcing block 330 is squeezed and moves into the movable groove 328 away from the reinforcing groove 331. Pull the mounting rod 323 to disengage from the mounting groove 325, thus completing the disassembly of the sealing cap 321.

[0025] The fixed base 341 is snapped onto the outer wall of the bottom end of the connector body 1. When an external object hits the connector, the first spring plate 340 connects the two second spring plates 347 into a whole. When one side is impacted, the impact force can be transmitted to the other side through the first spring plate 340. At the same time, the second spring plate 347 drives the T-shaped slider 346 to slide in the slide groove 345, so that the second spring plate 347 compresses the buffer spring 349. The buffer spring 349 absorbs the impact force through elastic deformation. At the same time, the movable rod 348 slides in the annular block 343 and the fixed rod 342 to further disperse the force. The first spring plate 340 pulls the second spring plates 347 on both sides in sync, so that the impact force is transmitted evenly and avoids excessive force on one side.

[0026] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
