[0029] A bidirectional submersible pump according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0030] Reference Figure 1 The present invention aims to provide an embodiment of a bidirectional submersible pump.

[0031] A bidirectional submersible pump according to an embodiment of this utility model, referring to... Figure 1 and Figure 2The system includes a motor 100, a first pump head, and a second pump head. The motor 100 drives the first and second pump heads to pump water. The first and second pump heads are symmetrically arranged about the motor 100. The motor 100 has an output shaft 110, which extends to both ends along the axial direction of the motor 100. The first pump head includes a first pump housing 120 and a first impeller 130. The first pump housing 120 is connected to the motor 100, and the first impeller 130 is located inside the first pump housing 120 and connected to one end of the output shaft 110. The second pump head includes a second pump housing 140 and a second impeller 150. The second pump housing 140 is connected to the motor 100, and the second impeller 150 is located inside the second pump housing 140 and connected to the other end of the output shaft 110.

[0032] It is understood that by setting up a motor 100, a first pump head, and a second pump head, the motor 100 can drive the first pump head and the second pump head to pump water. Therefore, compared with the traditional single-pump submersible pump, the bidirectional submersible pump of this invention has higher pumping efficiency and larger water flow, meeting the requirements of customers.

[0033] Furthermore, by setting an output shaft 110, the motor 100 outputs rotational power through the output shaft 110. By setting a first pump housing 120, a first impeller 130, a second pump housing 140, and a second impeller 150, the output shaft 110 simultaneously drives the first impeller 130 and the second impeller 150 to rotate simultaneously, so that the first impeller 130 and the second impeller 150 pump water in the first pump housing 120 and the second pump housing 140 respectively. The submersible pump of this invention has a simple power structure and does not require a complex transmission structure, which makes the submersible pump easy to manufacture and helps to reduce manufacturing costs.

[0034] In some embodiments of this utility model, reference is made to Figure 2 The output shaft 110 has a first transmission section 160 and a second transmission section 170 at its two ends, respectively. The first impeller 130 is provided with a first mounting hole, and the second impeller 150 is provided with a second mounting hole. The first mounting hole cooperates with the first transmission section 160. A first transmission key 180 and a first keyway for transmission are provided between the first mounting hole and the first transmission section 160. The second mounting hole cooperates with the second transmission section 170. A second transmission key 190 and a second keyway for transmission are provided between the second mounting hole and the second transmission section 170.

[0035] Therefore, when the submersible pump is pumping water, the output shaft 110 of the motor 100 drives the first impeller 130 and the second impeller 150 to rotate through the first transmission key 180 and the second transmission key 190 respectively, so that the first impeller 130 and the second impeller 150 rotate stably, ensuring that the submersible pump achieves efficient water pumping.

[0036] In some embodiments of this utility model, reference is made to Figure 2 The first transmission section 160 is connected to the first threaded section 200, and the first threaded section 200 is provided with the first nut 210. The first nut 210 is tightened with the first threaded section 200 to prevent the first impeller 130 from disengaging from the output shaft 110. The second transmission section 170 is connected to the second threaded section 220, and the second threaded section 220 is provided with the second nut 230. The second nut 230 is tightened with the second threaded section 220 to prevent the second impeller 150 from disengaging from the output shaft 110.

[0037] Therefore, the first impeller 130 and the second impeller 150 are respectively installed in the first transmission section 160 and the second transmission section 170. Then, the first nut 210 is tightened with the first threaded section 200 to fix the first impeller 130 on the output shaft 110. Then, the second nut 230 is tightened with the second threaded section 220 to fix the second impeller 150 on the output shaft 110.

[0038] In some embodiments of this utility model, both the first pump housing 120 and the second pump housing 140 are provided with a water inlet frame 240, and both the first pump housing 120 and the second pump housing 140 are connected to the motor 100 through the water inlet frame 240.

[0039] It is understandable that the first pump casing 120 and the second pump casing 140 are each equipped with a water inlet frame 240, which has a water inlet. The water inlet frame 240 is provided with a water inlet, through which the first impeller 130 and the second impeller 150 draw water from the outside, ensuring stable water pumping by the submersible pump.

[0040] The first pump casing 120 and the second pump casing 140 are designed separately from the water inlet frame 240, which helps to reduce the manufacturing difficulty of the pump casing.

[0041] In some embodiments of this utility model, the first pump housing 120 is provided with at least one first support plate 250, and the second pump housing 140 is provided with at least one second support plate 260. The at least one first support plate 250 and the at least one second support plate 260 are arranged opposite to each other, and the at least one first support plate 250 and the at least one second support plate 260 cooperate to support the horizontally arranged submersible pump.

[0042] Understandably, by setting up the first support plate 250 and the second support plate 260, the submersible pump can be placed underwater. The first support plate 250 and the second support plate 260 work together to support the submersible pump, allowing it to be placed horizontally and ensuring that it can pump water normally even when the water level is low.

[0043] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3The first pump casing 120 includes a first cylinder 270 and a first guide tube 280 located inside the first cylinder 270. The first guide tube 280 houses a first impeller 130 and a first guide vane is provided inside the first guide tube 280. The first guide vane is used to guide the water flow drawn by the first impeller 130. The second pump casing 140 includes a second cylinder 290 and a second guide tube 300 located inside the second cylinder 290. The second guide tube 300 houses a second impeller 150 and a second guide vane is provided inside the second guide tube 300. The second guide vane is used to guide the water flow drawn by the second impeller 150.

[0044] It is understandable that by setting the first cylinder 270, the first guide cylinder 280, the second cylinder 290 and the second guide cylinder 300, with the first cylinder 270 and the first guide cylinder 280 being separate designs, and the second cylinder 290 and the second guide cylinder 300 being separate designs, the manufacturing difficulty of the first pump housing 120 and the second pump housing 140 is reduced.

[0045] Furthermore, the first guide vane and the second guide vane respectively guide the water flow pumped by the first impeller 130 and the second impeller 150, so that the water flow can move and be lifted quickly.

[0046] In some embodiments of this utility model, the first guide tube 280 and the second guide tube 300 have a detachable wear-resistant ring 310 inside, and the first impeller 130 and the second impeller 150 are accommodated inside the wear-resistant ring 310.

[0047] Since the first impeller 130 and the second impeller 150 are respectively arranged inside the first guide cylinder 280 and the second guide cylinder 300, by installing wear-resistant rings 310 inside both the first guide cylinder 280 and the second guide cylinder 300, the mud and sand in the water will be carried by the first impeller 130 and the second impeller 150 when pumping water. The mud and sand will rotate in the wear-resistant rings 310, which will prevent the mud and sand from damaging the first guide cylinder 280 and the second guide cylinder 300. After the wear-resistant rings 310 are worn, they can be replaced.

[0048] In some embodiments of this utility model, the first cylinder 270 and the second cylinder 290 are both made of stainless steel. Therefore, using stainless steel to manufacture the first cylinder 270 and the second cylinder 290 helps to reduce the weight of the submersible pump and makes the submersible pump easy to carry.

[0049] In some embodiments of this utility model, the first guide tube 280 and the second guide tube 300 are both made of rigid plastic. Therefore, using rigid plastic to manufacture the first guide tube 280 and the second guide tube 300 is beneficial to reducing the weight of the submersible pump, making the submersible pump easy to carry, while ensuring that the first guide tube 280 and the second guide tube 300 are not easily damaged.

[0050] In some embodiments of this utility model, reference is made to Figure 4 Both the first cylinder 270 and the second cylinder 290 are provided with a bend 330, thereby meeting the different water outlet direction requirements of customers by utilizing the bend 330.

[0051] In some embodiments of this utility model, a C-shaped handle 320 is provided on the outside of the motor 100, thereby making it convenient for staff to carry the submersible pump.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
