[0002] Fire pumps are power equipment specifically designed for fire protection systems. They provide a stable and high-pressure water flow to fire hoses, sprinkler systems, fire hydrants, etc., in the event of a fire, and ensure that the fire protection system can be quickly activated and continuously supply water in an emergency.
[0003] The patent application CN220726678U discloses a fire pump, including a mounting plate. Two mounting frames are fixedly connected to the top outer wall of the mounting plate, and support blocks are inserted into the inner walls of the two mounting frames. The pump body is fixedly connected to the top outer wall of the two support blocks. In this utility model, the mounting components facilitate quick and easy disassembly and assembly of the support blocks, thereby facilitating the disassembly and replacement of the pump body. Compared with the prior art, this fire pump uses a snap-fit fixing method instead of multiple bolts, enabling quick installation, disassembly, and replacement of the pump body, thus improving installation efficiency.
[0004] The aforementioned fire pump uses a snap-fit fixing method instead of multiple bolts, which allows for quick installation, disassembly, and replacement of the pump body, improving installation efficiency. However, when connecting the fire pump to the pipeline, it still uses a flange with bolts and nuts for connection. This connection method is relatively troublesome, time-consuming, and not conducive to pipeline installation in emergency situations or later maintenance. Utility Model Content
[0005] The purpose of this utility model is to provide a fire pump that facilitates quick pipe connection, so as to solve the technical problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A fire pump that facilitates quick pipe connection includes a three-phase motor, a pump body installed at the front end of the three-phase motor, an inlet flange pipe installed through the front end of the pump body, an outlet flange pipe installed through the top of the pump body, and quick-connect mechanisms installed on the outside of both the inlet flange pipe and the outlet flange pipe.
[0008] The quick-connect mechanism includes an adapter. A clamp one is movably installed between the upper and lower inner walls of the adapter near the front end. A clamp two is movably installed between the upper and lower inner walls of the adapter near the rear end. A latch is movably installed at the end of clamp one away from the adapter, and a buckle is fixedly installed at the end of clamp two away from the adapter.
[0009] Preferably, the adapters in both quick-connect mechanisms are fixedly connected to the pump body.
[0010] Preferably, the quick-connect mechanism further includes slopes provided on the inner walls of the upper and lower ends of clamp one and clamp two.
[0011] Preferably, the quick-connect mechanism further includes a tenon that penetrates the upper front end of the buckle, and a slot that penetrates the buckle body and is located directly behind the tenon.
[0012] Preferably, the tenon is engaged with the buckle via a slot, and after the buckle is engaged with the buckle, the tenon is located at the top of the buckle.
[0013] Preferably, sealing rings are snapped into the top center of the outlet flange pipe and the front center of the inlet flange pipe, and several connecting posts are fixedly installed on the top edge of the outlet flange pipe and the front edge of the inlet flange pipe.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This fire pump, which facilitates quick pipe connection, uses a quick-connect mechanism to work with the outlet flange pipe, inlet flange pipe, and connecting post. The flange face of the pipe is snapped onto the connecting post, which helps to limit the pipe and prevent slippage and misalignment between the flange face of the pipe and the flange face of the fire pump after connection. The outlet flange pipe and the inlet flange pipe are tightly clamped by clamp one and clamp two. After the bolt is snapped into the buckle, the tenon is inserted into the slot. The tenon blocks and limits the bolt, preventing it from springing back after being snapped into the buckle. This facilitates quick pipe installation of the fire pump and improves the efficiency of pipe installation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Combination Figures 1-3 A fire pump that facilitates quick pipe connection includes a three-phase motor 1, a pump body 2 installed at the front end of the three-phase motor 1, an inlet flange pipe 4 installed through the front end of the pump body 2, an outlet flange pipe 3 installed through the top of the pump body 2, and quick-connect mechanisms 5 installed on the outside of both the inlet flange pipe 4 and the outlet flange pipe 3.
[0023] See Figure 2 Furthermore, the quick-connect mechanism 5 includes an adapter 501. A clamp 502 is movably installed between the upper and lower inner walls of the adapter 501 near the front end. A clamp 503 is movably installed between the upper and lower inner walls of the adapter 501 near the rear end. A latch 504 is movably installed at the end of the clamp 502 away from the adapter 501. A buckle 505 is fixedly installed at the end of the clamp 503 away from the adapter 501.
[0024] The adapter 501 in both quick-connect mechanisms 5 is fixedly connected to the pump body 2.
[0025] The quick-connect mechanism 5 also includes slopes 508 on the inner walls of the upper and lower ends of clamp 1 502 and clamp 2 503.
[0026] Specifically, when using the quick-connect mechanism 5 to connect the pipes, first open clamp 1 502 and clamp 2 503, place the flange face of the pipe on the flange face of the outlet flange pipe 3, then rotate clamp 1 502 and clamp 2 503 to bring them closer together, and insert the bolt 504 into the buckle 505. The bolt 504 and buckle 505 limit clamp 1 502 and clamp 2 503. When clamp 1 502 and clamp 2 503 tighten the outlet flange pipe 3 and the pipe, the slope 508 contacts the outlet flange pipe 3 and the pipe to provide a buffer surface, which is conducive to clamp 1 502 and clamp 2 503 coming closer together. The method of connecting the pipe to the inlet flange pipe 4 is the same. The quick-connect mechanism 5 replaces bolts and nuts to connect the flange face, which facilitates the rapid installation of the fire pump and improves the installation efficiency of the pipe.
[0027] Example 2
[0028] See Figure 2Furthermore, based on Embodiment 1, the quick-connect mechanism 5 further includes a tenon 506 that penetrates the upper front end of the buckle 505, and a slot 507 that penetrates the buckle 505 and is located directly behind the tenon 506.
[0029] The tenon 506 is engaged with the buckle 505 via the slot 507, and after the bolt 504 is engaged with the buckle 505, the tenon 506 is located on top of the buckle 505.
[0030] A sealing ring 6 is snapped into the center of the top of the outlet flange pipe 3 and the center of the front end of the inlet flange pipe 4. Several connecting posts 7 are fixedly installed on the edge of the top of the outlet flange pipe 3 and the edge of the front end of the inlet flange pipe 4.
[0031] Specifically, when the pipeline is connected to the fire pump, the flange face of the pipeline is engaged with the connection post 7, which helps to limit the pipeline and prevent slippage between the flange face of the pipeline and the flange face of the fire pump after connection, thus avoiding misalignment. The sealing ring 6 seals the connection between the pipeline and the outlet flange pipe 3 and the inlet flange pipe 4. After the bolt 504 is engaged in the buckle 505, the tenon 506 is inserted into the slot 507. The tenon 506 blocks and limits the bolt 504, preventing the bolt 504 from springing back after being engaged in the buckle 505.
[0032] In actual operation, first open clamp 1 502 and clamp 2 503, place the flange face of the pipe on the flange face of the outlet flange pipe 3, so that the connecting column 7 is inserted into the flange of the pipe, and seal the connection between the pipe and the outlet flange pipe 3 and the inlet flange pipe 4 through the sealing ring 6.
[0033] After connecting the pipes and fire pump, rotate clamp 1 502 and clamp 2 503 to bring them closer together, and insert bolt 504 into buckle 505. Then insert tenon 506 into slot 507. Tenon 506 blocks and limits bolt 504 to prevent it from springing back after being inserted into buckle 505. When clamp 1 502 and clamp 2 503 tighten the outlet flange pipe 3 and the pipe, the slope 508 provides a buffer surface for contacting the outlet flange pipe 3 and the pipe, which is conducive to clamp 1 502 and clamp 2 503 coming closer together. The method of connecting the pipe to the inlet flange pipe 4 is the same as above.
[0034] After the pipeline is installed, when the fire pump is running, the three-phase motor 1 starts and drives the impeller in the pump body 2 to rotate, drawing water in through the pipeline connected to the inlet flange pipe 4, and then outputting it through the pipeline connected to the outlet flange pipe 3.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
