The telescopic rod 5 and the first spring 6 provide a buffering effect between the fixed frame 2 and the sliding frame 3, so that the wheels 4 of the fire pump 1 can pass through uneven roads relatively smoothly, thereby improving the adaptability of the fire pump 1 to the terrain. When in use, the filter element is used to filter the water source pumped into the ground to avoid impurities mixed in the external water source from causing blockage in the fire pump 1, thereby improving the service life of the fire pump 1; the filter element includes a mounting frame 9 and a filter screen 91. A through opening is opened on the upper side of the pipe wall of the water inlet pipe 7 of the fire pump 1. The mounting frame 9 is installed in an arc shape and fits into the through opening of the fire pump 1. The inner wall of the mounting frame 9 is a circular ring adapted to the inner diameter of the water inlet pipe 7. A filter screen 91 is installed in the circular ring of the mounting frame 9. The filter screen 91 is used to filter the water flowing through the water inlet pipe 7.

[0023] like Figure 1 、 Figure 3 and Figure 4 As shown, a first guide rod 10 is symmetrically fixed to the outer side wall of the water inlet pipe 7, and the mounting frame 9 is slidably mounted on the first guide rod 10. A second spring 11 is provided between the mounting frame 9 and the first guide rod 10. The second spring 11 has a tendency to lift the mounting frame 9 upward, and a fastener is provided on the outer tube wall of the water inlet pipe 7. The fastener is locked on the mounting frame 9. After the fastener is unlocked on the mounting frame 9, the mounting frame 9 will pop up along the first guide rod 10 under the action of the second spring 11, so that the filter screen 91 in the mounting frame 9 pops out of the water inlet pipe 7, thereby facilitating the cleaning of impurities filtered out of the filter screen 91.

[0024] like Figure 1 and Figure 3 As shown, the fastener includes a wedge block 12, a second guide rod 13 and a third spring 14. The second guide rod 13 is symmetrically fixed to the front side of the fire pump 1. The wedge block 12 is slidably connected to the second guide rod 13. The wedge block 12 is snapped onto the mounting frame 9. A third spring 14 is provided on the outside of the second guide rod 13. The third spring 14 is connected between the wedge block 12 and the fire pump 1. The third spring 14 has a tendency to stretch and squeeze the wedge block 12. Under the action of the third spring 14, the wedge block 12 is snapped and limited to the mounting frame 9.

[0025] like Figure 3 As shown, an electric push rod 15 is installed on the front side of the fire pump 1, and a push block 151 is fixed to the telescopic rod 5 of the electric push rod 15. The push block 151 is in contact with the wedge block 12. The push block 151 is driven by the electric push rod 15 to squeeze on the wedge block 12, so that the wedge block 12 slides on the second guide rod 13 to overcome the elastic force of the third spring 14 and disengages from the installation, so that the installation frame 9 and the filter screen 91 thereon automatically pop up under the action of the second spring 11, making it convenient for the user to clean the filter screen 91.

[0026] like Figure 1 and Figure 5 As shown, a support rod 16 is fixed to the outer wall of the fire pump 1, and the support rod 16 is L-shaped. The upper end of the support rod 16 is hinged with an L-shaped handle 17, and the gripping end of the handle 17 is provided with an anti-slip texture. A fixing sleeve 18 is slidingly provided on the handle 17, and the fixing sleeve 18 is used to slide on the hinge point of the support rod 16 and the handle 17, so that the support rod 16 and the handle 17 form a push rod that is convenient for pushing the fire pump 1. A limiting pad 19 is fixed to the support rod 16 near the hinge with the handle 17, and the limiting pad 19 is used to limit the fixing sleeve 18 at the hinge of the support rod 16 and the handle 17. By sliding the fixing sleeve 18 away from the hinge of the support rod 16 and the handle 17, the handle 17 can be rotated and folded onto the support rod 16, thereby saving the space occupied by the handle 17.

[0027] When the fire pump 1 needs to be moved, the user can hold the handle 17 and push the fire pump 1. Since the fire pump 1 is equipped with four wheels 4 at the bottom, these wheels 4 are connected to the fixed frame 2 through the sliding frame 3, and the telescopic rod 5 and the first spring 6 provide a buffering effect, which enables the fire pump 1 to maintain stable movement even on uneven ground, effectively reducing the damage to the equipment caused by ground bumps. Before the fire pump 1 starts working, the operator must ensure that the filter element in the water inlet pipe 7 is in normal working condition. Since the filter element is composed of a mounting frame 9 and a filter screen 91, it is installed inside the water inlet pipe 7 to filter impurities in the water source to prevent these impurities from entering the fire pump 1 and causing blockage or damage. If the filter screen 91 accumulates too many impurities and affects the normal pumping operation of the fire pump 1, the user can start the electric push rod 15 to achieve convenient cleaning of the filter screen 91. First, activate the electric push rod 15. The push block 151 on the telescopic rod 5 of the electric push rod 15 will squeeze the wedge block 12, so that the wedge block 12 overcomes the resistance of the third spring 14 and slides along the second guide rod 13, thereby releasing the lock on the mounting frame 9. At this time, after the limit of the wedge block 12 is lost, the mounting frame 9 and the filter screen 91 therein will pop out along the first guide rod 10 under the action of the second spring 11, so as to achieve the effect of quickly cleaning the filter screen 91. In order to facilitate movement and storage, the fire pump 1 is also equipped with a foldable handle 17. When not in use, the user can rotate the handle 17 to a position parallel to the support rod 16 and lock it on the support rod 16 by sliding the fixing sleeve 18. This saves space and ensures the overall compactness of the equipment. When the handle 17 needs to be used, it is only necessary to slide the fixing sleeve 18 to the hinged joint of the support rod 16 and the handle 17 to lock it, and the handle 17 can be easily unfolded, making it convenient for the user to push the fire pump 1.
