[0001] The utility model relates to the technical field of fire pumps, in particular to a fire pump with quick pipeline connection. Background Art

[0002] Fire pumps refer to pumps used for firefighting purposes, such as fire extinguishing, water supply, and pressure boosting. Fire pumps are usually driven by electric motors or internal combustion engines. They suck in and pressurize water or other liquids through the rotation of the impeller, and then transport them to where they are needed through pipelines. The main features of fire pumps are large flow, high head, and high reliability. They can start quickly in an emergency and provide sufficient water volume and pressure to meet the needs of firefighting.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A fire pump with quick pipe connection includes a pump body 1, a water outlet pipe 2 and a horizontal water inlet pipe 3. The horizontal water inlet pipe 3 is designed to be disconnected, a connecting frame 8 is arranged on one section of the horizontal water inlet pipe 3, a slot 13 corresponding to the connecting frame 8 is arranged on the pump body 1, an upper top groove 15 is arranged on the connecting frame 8, a positioning block 16 is arranged in the upper top groove 15 through an upper mechanism, a positioning hole is arranged on the pump body 1, a connecting pipe 4 is arranged between the two sections of the horizontal water inlet pipe 3, a vertical water inlet pipe 5 is arranged on the connecting pipe 4, a rotating motor 10 is arranged on the pump body 1 through a supporting mechanism, and the rotating motor 10 is connected to the connecting pipe 4 through a rotating mechanism.

[0023] The vertical water inlet pipe 5 and a section of the horizontal water inlet pipe 3 are both provided with an opening and closing plate 7 through an opening and closing motor 6. The opening and closing motor 6 can drive the opening and closing plate 7 to rotate, thereby realizing the opening and closing operations of the horizontal water inlet pipe 3 and the vertical water inlet pipe 5.

[0024] The upper push mechanism includes an upper push spring 17 arranged in the upper push groove 15, and the two ends of the upper push spring 17 are elastically connected to the outer wall of the positioning block 16 and the inner bottom wall of the upper push groove 15 respectively. The positioning hole is connected to the slot 13 and corresponds to the positioning block 16. The positioning hole is below the rotating motor 10. The positioning block 16 is in the positioning hole, which can realize the connection between the connecting frame 8 and the pump body 1. The positioning hole is below the rotating motor 10 and is blocked by the support plate 9 and the rotating motor 10, which can reduce the probability of the positioning block 16 being detached from the positioning hole due to accidental touch.

[0025] The supporting mechanism includes two supporting plates 9 arranged on the pump body 1, one of which is fixedly connected to the housing of the rotating motor 10, and the other is rotatably connected to the output shaft of the rotating motor 10. The two supporting plates 9 realize the stable installation of the rotating motor 10 relative to the pump body 1.

[0026] The rotating mechanism includes a gear 11 installed on the output shaft of the rotating motor 10, and a rack 12 meshing with the gear 11 is provided on the outer wall of the connecting pipe 4. As shown in the figure, when the rack 12 is meshed with the gear 11, after the rotating motor 10 is started, the connecting pipe 4 and the vertical water pipe 5 can be driven to rotate and adjust the direction with the help of the above components.

[0027] Annular connecting grooves 14 are provided on the outer walls at both ends of the connecting pipe 4, and the two-section horizontal water-inlet pipes 3 are both sealingly slidably arranged in the annular connecting grooves 14. The sealed sliding connection is a prior art, and the details are not repeated here, and reference can be made to the prior art disclosure.

[0028] When the utility model is used, starting the vertical opening and closing motor 6 can drive the opening and closing plate 7 to rotate, thereby realizing the opening and closing of one section of the horizontal water inlet pipe 3 and the vertical water inlet pipe 5. When the vertical water inlet pipe 5 is in a closed state, water can be sprayed out through the horizontal water inlet pipe 3. Similarly, when one section of the horizontal water inlet pipe 3 is in a closed state, water can be sprayed out through the vertical water inlet pipe 5.

[0029] When it is necessary to connect with the cross-over pipes of different angles and directions, it can be connected to the vertical water pipe 5. After starting the rotating motor 10, the gear 11 can be driven to rotate. The gear 11 can drive the connecting pipe 4 and the vertical water pipe 5 to rotate and adjust the position relative to the two sections of the horizontal water pipe 3 with the help of the rack 12. Corresponding adjustments can be made according to specific circumstances.

[0030] In the present solution, the positioning block 16 in the positioning hole below the rotating motor 10 is pressed, and then the positioning block 16 can compress the upper spring 17 and disengage from the positioning hole, and then the connecting frame 8 is moved horizontally to disengage it from the pump body 1, and one section of the water pipe 3 is moved horizontally to disengage it from the connecting pipe 4, and then the limit of the connecting pipe 4 is released, which can realize the convenient disassembly of multiple components in the device, and improve the convenience of inspection, maintenance and replacement of multiple components of the device.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
