[0002] A float-type submersible centrifugal pump is a special type of submersible pump that combines float technology with the functions of a submersible centrifugal pump. Float-type submersible centrifugal pumps are mainly used in situations where water levels fluctuate significantly and the head is relatively high, such as lakes, rivers, and reservoirs. By utilizing a float, the pump unit can operate submerged while simultaneously floating in the water, thus achieving stable operation at varying water levels.

[0003] In the prior art, the floating box submersible centrifugal pump is generally an integrated structure, usually including a submersible centrifugal pump, a support plate and multiple floating boxes. Although the floating box submersible centrifugal pump can pump water normally, it is inconvenient to remove the submersible centrifugal pump and multiple floating boxes from the support plate. When the submersible centrifugal pump and multiple floating boxes are damaged and need to be replaced, they cannot be disassembled and replaced, which is quite inconvenient. Therefore, a detachable floating box submersible centrifugal pump is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-3 A detachable floating box submersible centrifugal pump includes a submersible centrifugal pump 1 and a support plate 2. The bottom of the support plate 2 is connected to a uniformly distributed floating box 3 via a first mounting mechanism. The bottom of the floating box 3 is connected to the submersible centrifugal pump 1 via a second mounting mechanism. A water pump 4 is installed inside the floating box 3.

[0022] It should be noted that the specific models and specifications of the submersible centrifugal pump 1 and water pump 4 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described. Both can be powered by external equipment and controlled to turn on and off.

[0023] It should be noted that the first mounting bolt 6, the first mounting nut, the second mounting bolt 8, the second mounting nut, the support plate 2, and the float 3 are all made of stainless steel, which is not easy to rust and has a long service life.

[0024] It should be noted that the support plate 2 has an internal cavity filled with foam, the float box 3 has an internal water storage cavity, and the float box 3 located between the outer wall of the float box 3 and the water storage cavity has an internal filling cavity arranged in a "U" shape. The filling cavity has a layer of foam inside. The foam material has extremely low density and a large number of air pores, which allows the support plate 2 and the float box 3 to float easily on the water surface.

[0025] It should be noted that the top of the float box 3 is initially an open structure. After the water pump 4 is installed in the inner bottom of the float box 3, the cover plate is then welded to the top of the float box 3.

[0026] The first mounting mechanism includes a first mounting plate 5, a first mounting bolt 6 and a first mounting nut symmetrically arranged on both sides of the float 3; the first mounting plate 5 is fixedly connected to the float 3, the first mounting plate 5 has a first lower mounting hole for the first mounting bolt 6 to be inserted into, the support plate 2 has a first upper mounting hole for the first mounting bolt 6 to be inserted into, and the first mounting bolt 6 is threadedly connected to the first mounting nut.

[0027] It should be noted that by inserting the first mounting bolt 6 into the first upper mounting hole and the first lower mounting hole, and then tightening the first mounting nut, the float box 3 can be installed and fixed, and it is also convenient to disassemble and replace the float box 3.

[0028] The second mounting mechanism includes a second mounting plate 7, a second mounting bolt 8, and a second mounting nut symmetrically arranged on both sides of the submersible centrifugal pump 1. The bottom of the second mounting plate 7 is fixedly connected to the submersible centrifugal pump 1. The top of the second mounting plate 7 has a second lower mounting hole for inserting the second mounting bolt 8. The top of the support plate 2 has a second upper mounting hole for inserting the second mounting bolt 8. The second mounting bolt 8 is threadedly connected to the second mounting nut.

[0029] It should be noted that by inserting the second mounting bolt 8 into the second upper mounting hole and the second lower mounting hole, and tightening the second mounting nut, the submersible centrifugal pump 1 can be installed and fixed, and the submersible centrifugal pump 1 can also be disassembled, which is quite convenient.

[0030] Furthermore, a drain pipe 9 is provided on the top of the submersible centrifugal pump 1, a suction pipe 10 is provided on one side of the submersible centrifugal pump 1, a filter cover is provided at one end of the suction pipe 10, and a first round hole for inserting the drain pipe 9 is provided on the top of the support plate 2.

[0031] It should be noted that the filter cover can prevent larger debris from entering the interior of the submersible centrifugal pump 1.

[0032] Furthermore, a water supply pipe is fixedly connected to the top of the float 3, and a second round hole for inserting the water supply pipe is opened on the top of the support plate 2. The interior of the water supply pipe is connected to the interior of the float 3, and a first sealing cap 11 is threadedly connected to the top of the water supply pipe.

[0033] It should be noted that water can be injected into the pontoon 3 through the water filling pipe. When the four pontoons 3 are filled with water, they will be located below the water surface, and the support plate 2 will be located above the water surface. When the four pontoons 3 are not filled with water, the four pontoons 3, the submersible centrifugal pump 1 and the support plate 2 will be placed in the water. Two-thirds of the pontoons 3 will float on the water surface, and the submersible centrifugal pump 1 will also be moved out of the water for easy inspection of its status.

[0034] Furthermore, the top of the water pump 4 is fixedly connected to a water outlet pipe 12 that passes through the top of the float box 3, and the top of the support plate 2 is provided with a third round hole for the water outlet pipe 12 to be inserted. The top of the water outlet pipe 12 is threadedly connected to a second sealing cap 13.

[0035] It should be noted that the water outlet pipe 12 can drain the water inside the float box 3, and the water pump 4 will drain a portion of the water inside the float box 3 through the water outlet pipe 12. When the water inside the float box 3 decreases, the four float boxes 3 will move upward.

[0036] Furthermore, the water pump 4 is installed at the bottom of the float box 3, and a suction pipe 10 is provided on one side of the water pump 4. The top of the float box 3 is attached to the bottom of the support plate 2.

Then, by inserting the second mounting bolt 8 into the second upper mounting hole and the second lower mounting hole, and tightening the second mounting nut, the submersible centrifugal pump 1 can be installed and fixed, and it is also convenient to disassemble the submersible centrifugal pump 1.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
