[0017] The present utility model will be further described below with reference to the drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those with ordinary skills in the field to which the present utility model belongs.

[0018] Embodiment

[0019] Figure 1 is a schematic diagram of the filtration state of the water suction pipe of the present utility model with a structure facilitating the replacement of the water inlet head, Figure 2 is a schematic diagram of the cleaning state of the water suction pipe of the present utility model with a structure facilitating the replacement of the water inlet head, Figure 3 is an exploded cross-sectional view of the water suction pipe of the present utility model with a structure facilitating the replacement of the water inlet head, as Figures 1-3As shown in the figure, the utility model provides a water suction pipe facilitating the replacement of a water inlet head, which comprises a water suction pipe 1 and a water inlet head 2. A first installation ring groove 3 is sleeved on the water suction pipe 1, and the first installation ring groove 3 is threadedly connected with a second installation block 4 connected to the top end of the water inlet head 2. A first water inlet hole group is arranged at the bottom and side wall of the water suction pipe 1, and the first water inlet hole group comprises a plurality of uniformly distributed first water inlet holes 5. A second water passing hole group is arranged at the bottom and side wall of the water inlet head 2, and the second water passing hole group comprises a plurality of uniformly spaced water inlet filtering holes 7 and second water passing holes 6, and the second water passing holes 6 are located above the water inlet filtering holes 7. The first water inlet hole group is located below the first installation ring groove 3.

[0020] During the threaded connection process of the water suction pipe 1 and the water inlet head 2, first, the bottom of the water suction pipe 1 is inserted into the water inlet head 2 until the second installation block 4 contacts the bottom of the first installation ring groove 3, and then the water inlet head 2 is rotated to make the second installation block 4 threadedly connected with the first installation ring groove 3. After the second installation block 4 is screwed tightly with the first installation ring groove 3, the first water inlet holes 5 on the side wall correspond to the water inlet filtering holes 7 on the side wall, and the first water inlet holes 5 at the bottom correspond to the water inlet filtering holes 7 at the bottom, completing the adjustment of the filtering state. The water in the pond sequentially passes through the water inlet filtering holes 7 and the first water inlet holes 5 and enters the water suction pipe 1 and is pumped out.

[0021] After pumping is completed, it can be adjusted to the cleaning state. There are small-particle impurities in the water suction pipe 1 that can pass through the water inlet filtering holes 7. Rotate the water inlet head 2 downward until the second water passing holes 6 on the side wall are correspondingly connected with the first water inlet holes 5 on the side wall, and the first water inlet holes 5 at the bottom are separated from the second water passing hole group at the bottom. The small-particle impurities in the water suction pipe 1 can be washed by water and leave the water suction pipe 1 through the first water inlet holes 5 and the second water passing holes 6. According to the mud content of the water to be pumped in the pond, the degree of coincidence and connection between the first water inlet holes 5 and the water inlet filtering holes 7 or the second water passing holes 6 can be adjusted, which can accelerate the water suction speed of the water suction pipe 1.

[0022] A first elastic ring gasket 9 and a first sealing ring 10 are sequentially sleeved from top to bottom on the inner top of the first installation ring groove 3. A sealing ring groove 8 is arranged at the end of the first installation ring groove 3, and an internal thread is arranged on the inner side wall of the first installation ring groove 3 between the sealing ring groove 8 and the first sealing ring 10.

[0023] The first elastic ring gasket 9 is in a compressed state after the first installation ring groove 3 and the second installation block 4 are screwed tightly. The first sealing ring 10 connected to the first elastic ring gasket 9 moves accordingly. During the movement of the first sealing ring 10 along with the first elastic ring gasket 9, it is always tightly connected to the top end of the second installation block 4, preventing water and mud from entering the water suction pipe 1 through the gap between the two. When the first water inlet holes 5 correspond to the second water passing holes 6, the first elastic ring gasket 9 is not compressed and the first sealing ring 10 still contacts and connects with the second installation block 4. The first elastic ring gasket 9 and the first sealing ring 10 cooperate with each other to seal the gap between the first installation ring groove 3 and the second installation block 4.

[0024] The diameter of the outer sidewall of the second mounting block 4 is smaller than the diameter of the outer sidewall of the water inlet head 2. A second sealing ring 12 and a second elastic ring gasket 11 are sequentially sleeved on the connection part between the second mounting block 4 and the water inlet head 2 from top to bottom.

[0025] When the second mounting block 4 and the first mounting ring groove 3 are in a tightened state, the second elastic ring gasket 11 is compressed by the bottom of the sealing ring groove 8, and the second sealing ring 12 and the second elastic ring gasket 11 are inside the sealing ring groove 8. The second sealing ring 12 is connected to the second elastic ring gasket 11. The second sealing ring 12 contacts the top of the sealing ring groove 8 and compresses the second elastic ring gasket 11 driven by the sealing ring groove 8. The arrangements of the second sealing ring 12 and the sealing ring groove 8 prevent water and mud from entering the suction pipe 1 through the gap between the two. When the first water inlet hole 5 corresponds to the second water passing hole 6, the second elastic ring gasket 11 is not compressed and the second sealing ring 12 still contacts and connects with the top of the sealing ring groove 8. The second elastic ring gasket 11 and the second sealing ring 12 cooperate with each other to seal the gap between the sealing ring groove 8 and the water inlet head 2.

[0026] The diameters of the outer sidewalls of the second sealing ring 12 and the second elastic ring gasket 11 match the diameter of the inner sidewall of the sealing ring groove 8. The settings of the three diameters enable the sealing ring groove 8 to wrap the second sealing ring 12 and the second elastic ring gasket 11 inside it. The second sealing ring 12 and the second elastic ring gasket 11 contact both the bottom and the sidewall of the sealing ring groove 8, preventing water and mud from entering the suction pipe 1 from here.

[0027] The diameter of the outer sidewall of the water inlet head 2 is the same as the diameter of the outer sidewall of the first mounting ring groove 3.

[0028] The diameter of the inner sidewall of the water inlet head 2 is the same as the diameter of the inner sidewall of the second mounting block 4, and the diameter of the inner sidewall of the second mounting block 4 is the same as the diameter of the outer sidewall of the end of the suction pipe 1.

[0029] Therefore, for the suction pipe with a water inlet head that is convenient to replace according to the above structure of the present utility model, by replacing the water inlet filter holes and the second water passing holes corresponding to the first water inlet holes, the two operations of pumping water filtration and suction pipe cleaning are realized. The threaded connection between the water inlet head and the suction pipe facilitates the replacement of the water inlet head.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
