Description

Technical Field

[0001] This utility model relates to the field of fire pumps, and in particular to a fire pump that is easy to maintain. Background Technology

[0002] Fire pumps, as key equipment in fire protection systems, play a vital role in fire suppression. They provide a stable supply of fire-fighting water with sufficient pressure and flow, ensuring that fire-fighting equipment such as fire hydrants and automatic sprinkler systems can operate effectively, promptly controlling and extinguishing fires, thereby protecting people's lives and property.

[0003] However, existing fire pumps have many maintenance problems in actual use. The pipe connections of traditional fire pumps are usually installed with multiple bolts. When it is necessary to remove or install them, it is usually necessary to use bolt tools to tighten and loosen them multiple times. This results in a lot of time and effort being spent on disassembly work during maintenance and repair, which reduces maintenance efficiency. Therefore, a fire pump that is easy to maintain is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fire pump that is easy to maintain, aiming to improve the problem in the prior art that "installation is done by bolts, which requires a lot of time to install or remove, resulting in low installation efficiency".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire pump that is easy to maintain, comprising a pump body, a connecting pipe 1 provided on the pump body, a limiting component provided on the connecting pipe 1, a connecting pipe 2 connected to the connecting pipe 1 by means of the limiting component, the limiting component including a fixing ring fixedly connected to the outer wall of the connecting pipe 1 near the pump body, a circular ring slidably sleeved on the outer wall of the connecting pipe 1, the circular ring being located near the connecting pipe 2, a connecting rod hinged on the circular ring near the connecting pipe 2; a plurality of fixing frames are circumferentially spaced at one end of the connecting pipe 1 away from the pump body, the fixing frames having longitudinally arranged sliding grooves, a guide rod slidably connected to the fixing frames through the sliding grooves, a limiting block connected to the guide rod, and the other end of the connecting rod hinged to the guide rod.

[0006] As a further description of the above technical solution:

[0007] Preferably, the limiting block is set to an L-shape.

[0008] Preferably, the circular ring is elastically connected to the fixed ring by a spring, with one end of the spring fixedly connected to the circular ring and the other end of the spring fixedly connected to the fixed ring.

[0009] Preferably, it also includes a locking component, which includes a first fixing block disposed on the ring, a second fixing block disposed on the fixing ring, and a locking block. The first fixing block is provided with a slot, and one end of the locking block is provided with a locking block that matches the slot, and the other end is connected to the second fixing block via a threaded rod.

[0010] Preferably, the second fixing block is provided with a slot, and the locking block is provided with a corresponding prong at the end connected to the second fixing block, and the prong is slidably connected in the slot.

[0011] Preferably, the connecting rod passes through the slide groove and is hinged to the middle of the guide rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, by moving the fixed block one, the connecting rod is driven to push the limiting block outward, thereby quickly releasing the limiting of the connecting pipe two. At this time, the connecting pipe two can be quickly removed from the connecting pipe one, thus facilitating disassembly and maintenance, improving maintenance efficiency and convenience.

[0014] 2. In this utility model, by rotating the threaded rod and connecting it to the locking block bolt, the locking block can move downwards and drive the locking block into the slot, thereby limiting the first fixing block and the ring. This prevents the ring and the limiting block from moving, allowing the second connecting pipe and the first connecting pipe to be stably connected, thus improving the stability after installation.

[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] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a fire pump that is easy to maintain, comprising a pump body 1, a connecting pipe 2 on the pump body 1, a limiting component on the connecting pipe 2, and a connecting pipe 4 connected to the connecting pipe 2 by means of the limiting component. The limiting component includes a fixing ring 26 fixedly connected to the outer wall of the connecting pipe 2 near the pump body 1, and a circular ring 28 slidably sleeved on the outer wall of the connecting pipe 2 near the connecting pipe 4. The circular ring 28 is elastically connected to the fixing ring 26, and a connecting rod 24 is hinged to the circular ring 28 near the connecting pipe 4. Several fixing frames 2 are arranged circumferentially at intervals on the connecting pipe 2 away from the pump body 1. 3. A longitudinally arranged sliding groove is provided on the fixed frame 23. A guide rod 22 is slidably connected to the fixed frame 23 through the sliding groove. A limit block 21 is connected to the guide rod 22. The other end of the connecting rod 24 is hinged to the guide rod 22. When the limit is released, the ring 28 is pushed outward. The movement of the ring 28 pushes the connecting rod 24. The connecting rod 24 is set in an inclined position, which allows the connecting rod 24 to rotate. The end of the connecting rod 24 away from the ring 28 slides upward, which can quickly drive the limit block 21 to open outward and quickly release the limit of the connecting tube 24, thus facilitating maintenance. The fixed frame 23 can provide support and guidance.

[0022] Furthermore, to ensure that the connecting rod 24 can stably drive the guide rod 22 to slide up and down when it rotates, the connecting rod 24 passes through the groove and is hinged to the middle of the guide rod 22.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The limiting block 21 is set in an L shape. The right angle of the limiting block 21 can be locked on the left side of the connecting pipe 2 4, so that the connecting pipe 2 4 and the connecting pipe 1 2 can be quickly installed and connected. The limiting block 21 is slidably connected to the left side of the fixed frame 23, so the limiting block 21 can be stably moved up and down by the fixed block 23.

[0024] Furthermore, the circular ring 28 is elastically connected to the fixed ring 26 via the spring 27. The two ends of the spring 27 are fixedly connected to the circular ring 28 and the fixed ring 26 respectively. When the circular ring 28 is moved outward, the spring 27 will be stretched. When the circular ring 28 is released, that is, when it is not necessary to open the limiting block 21 outward, the spring force of the spring 27 can make the circular ring 28 quickly return to its original position. Multiple sets of limiting blocks 21, connecting rods 24 and fixed blocks 25 are provided, and multiple sets of limiting blocks 21, connecting rods 24 and fixed blocks 25 are arranged in a circular array with the center point of connecting tube 2 as the center. By evenly arranging multiple sets of limiting blocks 21 around connecting tube 4 and connecting tube 2, connecting tube 4 and connecting tube 2 can be stably and quickly installed and limited. One end of the spring 27 is fixedly connected to the circular ring 28, and the other end of the spring 27 is fixedly connected to the fixed ring 26.

[0025] Reference Figure 1 , Figure 2 and Figure 3 It also includes a locking assembly for limiting the ring 28. The locking assembly includes a first fixing block 25 set on the ring 28, a second fixing block 32 set on the fixing ring 26, and a locking block. The first fixing block 25 is provided with a slot 33. One end of the locking block is provided with a locking block 34 that matches the slot 33, and the other end is connected to the second fixing block 32 through a threaded rod 31. The threaded rod 31 is rotatably connected to the second fixing block 32. The threaded rod 31 is also threadedly connected to the locking block 3. Therefore, rotating the threaded rod 31 can drive the locking block 3 to move up and down. The second fixing block 32 is provided with a slot. The locking block 3 is connected to the second fixing block 32 with a corresponding prong. The prong is slidably connected in the slot. The connecting rod 24 passes through the sliding groove and is hinged to the middle of the guide rod 22.

[0026] Working Principle: When maintaining the fire pump and disconnecting connecting pipe 24 from connecting pipe 12, first rotate the threaded rod 31 to engage with the locking block 3. This causes the locking block 3 to move the locking block 34 upwards, disengaging it from the slot 33. The limiting position of the ring 28 is then released. Next, by moving the fixing block 25, the ring 28 is pushed outwards. This stretches the spring 27, causing the ring 28 to rotate. Since the connecting rod 24 is angled, its outer end slides upwards, causing the guide rod 22 to slide upwards. The movement of the guide rod 22 moves the limiting block 21 outwards, disengaging it from connecting pipe 24. This quickly releases the limiting position of connecting pipe 24, allowing it to be easily disconnected from the pump. After removing the connecting pipe 1 from 2, the fire pump is maintained. After maintenance, the fixing block 1 25 is released. The reverse force generated by the stretching of the spring 27 will cause the ring 28 to quickly return to its original position, driving the connecting rod 24, guide rod 22 and limiting block 21 back to their initial positions. When it is necessary to connect the connecting pipe 2 to the connecting pipe 1, the ring 28 is moved to the left, causing the limiting block 21 to move outward. At this time, the connecting pipe 2 to the connecting pipe 1 can be connected. Since multiple sets of limiting blocks 21, connecting rod 24 and fixing block 1 25 are arranged in a circular array with the center point of the connecting pipe 1 as the center, multiple sets of limiting blocks 21 can evenly act on the connecting pipe 2. The L-shaped design of the limiting block 21 can lock its right angle on the connecting pipe 2, thereby allowing the connecting pipe 2 to be quickly installed and connected to the connecting pipe 1.

[0027] To prevent the ring 28 from moving and causing the limiting block 21 to loosen, the threaded rod 31 can be rotated. Since the threaded rod 31 is threadedly connected to the locking block 3, and the right side of the locking block 3 is slidably connected to the upper part of the fixing block 2 32, when the threaded rod 31 rotates, the locking block 3 moves downward. When the threaded rod 31 is rotated, the locking block 3 drives the locking block 34 to move downward until the locking block 34 is engaged in the slot 33 opened at the top of the fixing block 1 25. At this time, the ring 28 is quickly limited, ensuring the stability of the connection between the connecting pipe 2 4 and the connecting pipe 1 2.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
