[0008] 1. For the water pump structure of this sprinkler truck, driven by the electric telescopic rod, the sealing plug can be driven to move, and at the same time, the sealing gasket can be pressed through the annular boss, thereby sealing the drain pipe, so that the water inside the pump body will not leak. And driven by the reverse drive of the electric telescopic rod, the sealing plug can be driven to move in the reverse direction, and at the same time, the sealing plug can be displaced to the right side of the drain hole. At this time, the water inside the pump body can sequentially pass through the drain pipe, the fixed sleeve and the drain hole to drain to the outside of the pump body. Using this structure, the sprinkler truck can automatically open and close the drainage channel inside the drain pipe, and the operation is relatively convenient.

[0009] 2. For the water pump structure of this sprinkler truck, by manually rotating the bidirectional lead screw, the third support and the fourth support can be driven to move in the reverse direction, and at the same time, the sealing plug can be driven to move through the first support, so as to adjust the pressure of the sealing plug on the sealing gasket, so as to ensure that the sealing gasket can effectively seal the drain pipe through the annular boss. And when the sprinkler truck needs to drain water when the power is off, the operator can manually rotate the bidirectional lead screw in the reverse direction to drive the sealing plug to displace to the right side of the drain hole. Using this structure, the drainage channel inside the drain pipe can be opened and closed in two ways: manual and automatic. Description of the drawings

[0019] The following further details the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0020] The drawings in the embodiments of the present utility model: The different types of hatching lines in the figure are not marked according to the national standard, nor are the materials of the components required. It is to distinguish the cross-sectional views of the components in the figure.

[0021] Please refer to Figure 1-7, a water pump structure of a sprinkler truck, comprising a pump body 1, a water inlet end cover 2 fixedly installed on one side of the pump body 1, and a drain pipe 3 connected to the outside of one side of the water inlet end cover 2. A fixed bracket 4 is arranged at the bottom of one side of the water inlet end cover 2. An electric telescopic rod 5 located on one side of the drain pipe 3 is fixedly sleeved inside the fixed bracket 4. Through the drive of the electric telescopic rod 5, the sealing plug 7 can be driven to press the sealing gasket 15, so that the drainage channel inside the drain pipe 3 can be automatically closed through the sealing gasket 15. And through the reverse drive of the electric telescopic rod 5, the sealing plug 7 can be driven to move in the reverse direction while opening the drainage channel inside the drain pipe 3, so that the water inside the pump body 1 can be discharged to the outside. A fixed sleeve 6 is threadedly sleeved inside the drain pipe 3. A sealing plug 7 is movably sleeved inside the fixed sleeve 6. A push rod 8 is arranged on one side of the sealing plug 7. An adjusting mechanism 9 is fixedly installed between the push rod 8 and the electric telescopic rod 5. A drainage groove 10 located below the fixed sleeve 6 is opened on the inner side of the fixed bracket 4. Through the drainage groove 10, the fixed bracket 4 will not block the water discharged from inside the fixed sleeve 6. A limiting mechanism 11 is threadedly sleeved on the outside of one end of the fixed sleeve 6 and located outside the push rod 8. And an annular boss 12 located on one side of the sealing plug 7 is arranged inside the fixed sleeve 6. A drainage hole 13 located above the drainage groove 10 is opened inside the fixed sleeve 6. Through the drainage hole 13, the water inside the pump body 1 can be discharged to the outside of the pump body 1 through the drain pipe 3, the fixed sleeve 6 and the drainage hole 13 after the drainage channel inside the drain pipe 3 is opened.

[0022] Among them, a sealing gasket 15 located between the sealing plug 7 and the annular boss 12 is fixedly installed in the middle of one side of the sealing plug 7 through a bolt 14. Through the sealing gasket 15, the sealing plug 7 can squeeze the sealing gasket 15 through the annular boss 12 during the moving process, so that the drainage channel inside the drain pipe 3 can be sealed through the sealing gasket 15, preventing the water inside the pump body 1 from leaking to the outside.

[0023] Among them, the limiting mechanism 11 includes a limiting column 111 arranged on the end face of one side of the fixed sleeve 6 and a fixed cover 112 threadedly sleeved on the outside of the fixed sleeve 6 and located outside the push rod 8. A limiting disc 113 sleeved on the outside of the limiting column 111 and clamped on the outside of the push rod 8 is arranged inside the fixed cover 112. Through the limiting column 111, the limiting disc 113 can be limited, and at the same time, the push rod 8 can be limited and guided through the limiting disc 113, so that the sealing plug 7 will not rotate during the moving process, and then it is convenient to manually rotate the bidirectional lead screw 912.

[0024] Among them, the adjusting mechanism 9 includes a first support 92 fixedly sleeved outside the push rod 8 through a first fixing rod 91 and a second support 94 fixedly sleeved outside one end of the electric telescopic rod 5 through a second fixing rod 93. Inside both sides of the first support 92, a first connecting plate 96 and a second connecting plate 97 are respectively rotatably connected through fixing pins 95. Inside both sides of the second support 94, a third connecting plate 98 and a fourth connecting plate 99 are respectively rotatably connected through fixing pins 95. Inside the first connecting plate 96 and the third connecting plate 98, a third support 910 is jointly sleeved through a fixing pin 95. Inside the second connecting plate 97 and the fourth connecting plate 99, a fourth support 911 is jointly sleeved through a fixing pin 95. Inside the third support 910 and the fourth support 911, a bidirectional lead screw 912 is jointly threadedly sleeved. By rotating the bidirectional lead screw 912, while driving the third support 910 and the fourth support 911 to move in opposite directions, the push rod 8 can be pushed through the first support 92, so that the sealing plug 7 can press the sealing gasket 15, preventing the water inside the pump body 1 from leaking to the outside through the fixed sleeve 6. And by rotating the bidirectional lead screw 912 in the reverse direction, the sealing plug 7 can move towards one side of the limit disc 113, thereby opening the drainage channel inside the drain pipe 3, enabling the water pump to drain water manually.

[0025] When automatically draining water from the water pump, start the electric telescopic rod 5. While driving the push rod 8 to be pulled by the drive of the electric telescopic rod 5, the sealing plug 7 is driven to move until it stops moving when it contacts the limit disc 113. At this time, the drainage channel inside the drain pipe 3 is opened, and the water inside the pump body 1 is discharged to the outside in sequence through the drain pipe 3, the fixed sleeve 6, and the drain hole 13.

[0026] When manually draining water from the water pump, rotate the bidirectional lead screw 912. While driving the third support 910 and the fourth support 911 to move in opposite directions by the rotation of the bidirectional lead screw 912, the push rod 8 is pulled through the first support 92. While the push rod 8 moves, the sealing plug 7 moves synchronously until it stops moving when it contacts the limit disc 113. At this time, the drainage channel inside the drain pipe 3 is opened, and the water inside the pump body 1 is discharged to the outside in sequence through the drain pipe 3, the fixed sleeve 6, and the drain hole 13. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
