[0033] Insert the pump body 3 into the waterproof membrane 2 and into the shell 1. The waterproof membrane 2 completely wraps the pump body 3 and the fixing ring 18. Hold the part of the tightening belt 5 extending from the front end of the buckle 9 with one hand, and hold the buckle 9 with the other hand and push it backwards to make the top position of the waterproof membrane 2 begin to shrink. When the top of the waterproof membrane 2 shrinks until it is close to the outer wall of the pump body 3, pull the part of the tightening belt 5 extending from the front end of the buckle 9 to the left and fold it. Align the Velcro burr surface 7 with one of the Velcro original fur surfaces 8 and stick it to fix. The top of the waterproof membrane 2 has been close to the pump body 3. The shrinkage position of the top of the waterproof membrane 2 is limited by the fixing ring 4 to prevent the waterproof membrane 2 from falling down.

[0034] Reference Figure 2 , Figure 3 and Figure 5, the inside of the shell 1 is slidably connected with evenly distributed sliding rods 10, a connecting ring 11 is fixedly connected between the multiple sliding rods 10, the connecting ring 11 is slidably connected to the inner wall of the shell 1, a grounding ring 12 is fixed in the middle of the multiple sliding rods 10, the tops of the multiple sliding rods 10 are fixedly connected with springs 15, and the multiple springs 15 are arranged inside the shell 1, the pump body 3 is against the top of the connecting ring 11, the bottom of the inner wall of the shell 1 is fixedly connected with a limiting ring 13, the bottom of the inner wall of the limiting ring 13 is fixedly connected with a filter screen 14, the connecting ring 11 is against the top of the limiting ring 13, the left and right sides of the shell 1 are fixedly connected with handles 22, the inner and outer layers of the waterproof membrane 2 are coated with an anti-corrosion layer, and the bottom of the sliding rod 10 is set to a pointed shape.

[0035] After the pump body 3 enters the shell 1, it will rest against the top of the connecting ring 11. The connecting ring 11 will be pressed downward as a whole by the weight of the pump body 3 itself, so that the connecting ring 11 slides downward on the inner wall of the shell 1 and slides out multiple sliding rods 10 downward until the connecting ring 11 rests against the limit ring 13. The bottom of the sliding rod 10 is pointed and will be inserted into the soil until the grounding ring 12 touches the ground and stops, preventing the bottom of the shell 1 from being blocked by the soil. The pump body 3 is filtered through the filter screen 14 during operation. When the pump body 3 leaves, the shell 1 can be lifted by two handles 22 to make the sliding rod 10 leave the ground. At this time, the sliding rod 10 will no longer be affected by the gravity of the ground and the pump body 3 pressing on the connecting ring 11 and will be retracted back into the shell 1 through the rebound of multiple springs 15, and the connecting ring 11 will also slide upward in the shell 1 and be retracted until the grounding ring 12 rests against the bottom of the shell 1.

[0036] Reference Figure 2 , Figure 3 and Figure 5 A connecting block 16 is fixedly connected to the top of the shell 1, and evenly distributed clamping rods 17 are fixedly connected to the outer wall of the top of the connecting block 16. Multiple clamping rods 17 are respectively engaged with the top of the fixing ring 18. A sliding ring 19 is slidably connected to the outer wall of the pump body 3. The sliding ring 19 is arranged between the fixing ring 1 4 and the fixing ring 18. An evenly distributed spring 20 is fixedly connected to the top of the connecting block 16, and an extrusion ring 21 is fixedly connected to the top of the multiple springs 20, and the extrusion ring 21 is against the bottom of the fixing ring 18.

[0037] After the pump body 3 enters the shell 1, it continues to descend until the fixing ring 18 pushes open the multiple clamping rods 17. After the multiple clamping rods 17 are pushed open, the fixing ring 18 continues to fall. At this time, the multiple clamping rods 17 will close again and engage with the top of the fixing ring 18 to prevent the pump body 3 from separating from the shell 1. When the pump body 3 falls, the extrusion ring 21 will press against the bottom of the fixing ring 18 to prevent the pump body 3 from descending too fast and provide buffering through the rebound of the multiple springs 20. When the pump body 3 needs to be taken out, the sliding ring 19 is slid downward until the multiple clamping rods 17 are pushed open and then press against the fixing ring 18. When the multiple clamping rods 17 are pushed open, the pump body 3 is moved upward as a whole. Since the multiple clamping rods 17 are pushed open, the fixing ring 18 moves upward and leaves the engagement of the multiple clamping rods 17.

[0038] Working principle: When the extraction pump with a protective mechanism is used, the pump body 3 is inserted into the waterproof membrane 2 and then continues to be engaged into the housing 1. The pump body 3 will resist the connecting ring 11 in the housing 1 and press the connecting ring 11 down and slide according to its own weight. When the pump body 3 continues to move downward in the housing 1, the fixing ring 2 18 will push open the multiple clamping rods 17. After the clamping rods 17 are pushed open, the pump body 3 continues to descend. At this time, the multiple clamping rods 17 will close and engage on the top of the fixing ring 2 18. When the pump body 3 descends again, it will resist the spring 2 20 and be buffered by the rebound of the multiple extrusion rings 21. The multiple grounding rings 12 will extend out of the bottom of the housing 1 through the sliding of the connecting ring 11 until the connecting ring 11 slides down. The pump body 3 is supported by the limiting ring 13 and then stopped, and the grounding ring 12 is inserted into the underwater soil until the grounding ring 12 is close to the ground. At this time, the fixing ring 4 is located inside the waterproof membrane 2. One hand holds the part of the tightening belt 5 extending from the sun buckle 9, and the other hand holds the sun buckle 9 and pushes it backward to shrink the top range of the waterproof membrane 2 and tighten it to the outer wall of the pump body 3. After tightening, the part of the tightening belt 5 extending from the sun buckle 9 is pulled to the left and folded, and the Velcro burr surface 7 is aligned with one of the Velcro original hair surfaces 8 for pasting and fixing to prevent the top of the waterproof membrane 2 from loosening. After the waterproof membrane 2 is tightened and pasted and fixed, it is limited by the fixing ring 4 to prevent the tightened part of the top of the waterproof membrane 2 from sliding down.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
