However, when the fixed filter structure is used to block and filter the liquid inlet of the pump body, since the liquid inlet of the pump body is inserted and extended below the liquid level, it is inconvenient for the staff to observe and remove the bolts and screws that fix the filter structure when using tools to disassemble and clean the filter structure, thereby affecting the use effect of the submersible pump.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a pump body, an outer blocking cover is hingedly connected to the outer end of the water inlet at the bottom of the pump body, a blocking grille for blocking larger debris is provided through the outer curved surface of the outer blocking cover, an upper mounting block and a lower mounting block are respectively fixedly installed on the outer side of the water inlet at the bottom of the pump body and on the outer side of the upper end of the outer blocking cover, a swing column is rotatably connected to the outer top of the lower mounting block through a pin shaft, a limited position bayonet is provided at the outer end of the upper mounting block, a support block is fixedly installed on the upper top of the swing column, a support spring is fixedly installed on the circumference of the lower end of the support block, and a support ring is fixedly installed on the lower top of the support spring;

The outer curved surface of the inner blocking cover is provided with an adjustment grille for adjusting the gap size of the blocking grille, and a filter element for filtering the water inlet at the bottom of the pump body is placed inside the inner blocking cover.
[0008] Preferably, a sealing ring is embedded and bonded at the water inlet at the bottom of the pump body and the joint part of the upper end of the outer blocking cover, so that the water inlet at the bottom of the pump body and the joint part of the upper end of the outer blocking cover remain sealed.
[0009] Preferably, there are several blocking grilles, which are rotationally symmetrically distributed on the outer end surface of the outer blocking cover.
[0010] Preferably, the outer curved surface of the upper end of the swing column is movably connected to the inner wall of the limit bayonet, and the support spring is in a compressed state.
[0011] Preferably, the middle part of the support ring is movably connected to the outer curved surface of the middle part of the swing column, and the lower end surface of the support ring is movably connected to the upper end surface of the outer side of the upper mounting block, so that the swing column is supported and limited by the support spring and the support ring.

[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The utility model can block larger impurities in the liquid to be extracted by means of the blocking grille which penetrates through the outer curved surface of the outer blocking cover, so as to prevent the larger impurities from entering the water inlet at the bottom of the pump body and causing the pump body to be blocked. When the blocking grille blocks the larger impurities, the fastening nut is loosened by rotation. When the fastening nut is loosened, the adjusting column is rotated by the knob.

When the filter element needs to be replaced after being used for a long time, the support ring is pushed upward. When the support ring is pushed upward, it will move upward along the outer curved surface of the swing column and push the compressed support spring. When the support spring is pushed upward and compressed, the support limit of the swing column by the support spring and the support ring can be released. When the support limit of the swing column is released, the swing column is pushed to swing outward along the inner wall of the limit bayonet. When the swing column swings outward along the inner wall of the limit bayonet, the outer blocking cover can be opened to replace the filter element by pushing the outer blocking cover downward, thereby filtering the required extracted liquid and facilitating the replacement of the filter element.

The outer curved surface of the upper end of the swing column 6 fits and is movably connected to the inner wall of the limit bayonet 7. A support block 8 is fixedly installed on the top end of the swing column 6, and a support spring 9 is fixedly installed on the circumference of the lower end of the support block 8, and the support spring 9 is in a compressed state. A support ring 10 is fixedly installed on the top end below the support spring 9, and the middle part of the support ring 10 fits and is movably connected to the outer curved surface in the middle of the swing column 6, and the lower end surface of the support ring 10 fits and is movably connected to the upper end surface of the outer side of the upper mounting block 4, so that the swing column 6 is supported and limited by the support spring 9 and the support ring 10;
[0023] An adjusting column 11 is rotatably connected to the bottom of the outer blocking cover 2 through a rotating shaft, and a knob for rotating the adjusting column 11 is fixedly installed at the lower top of the adjusting column 11, and an inner blocking cover 12 is fixedly installed at the upper top of the adjusting column 11, and the lower end circumference of the inner blocking cover 12 is movably connected to the inner bottom of the outer blocking cover 2, and an adjusting grille 13 for adjusting the gap size of the blocking grille 3 is provided on the outer curved surface of the inner blocking cover 12, and a filter element 14 for filtering the water inlet at the bottom of the pump body 1 is placed inside the inner blocking cover 12, and the diameter of the filter element 14 is larger than the inner wall of the water inlet at the bottom of the pump body 1, and a fastening nut for locking and fastening the adjusting column 11 is threadedly connected to the outer curved surface of the lower end of the adjusting column 11.
[0024] Working principle: When in use, when the water inlet at the bottom of the pump body 1 extends to below the liquid level to extract liquid, the blocking grille 3 provided through the outer curved surface of the outer blocking cover 2 can block larger impurities inside the liquid to be extracted, so as to prevent larger impurities from entering the water inlet at the bottom of the pump body 1 and causing blockage of the pump body 1.

When the support limit of the swing column 6 is released, the swing column 6 is pushed to swing outward along the inner wall of the limit bayonet 7. When the swing column 6 swings outward along the inner wall of the limit bayonet 7, the outer blocking cover 2 can be pushed downward to open the filter element 14 for replacement, thereby filtering the required extracted liquid while facilitating the replacement of the filter element 14.
