[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0025] The following is a reference to the appendix. Figure 1 To be continued Figure 3 This invention describes a combined explosion-proof electric submersible pump.

[0026] A combined explosion-proof electric submersible pump, such as Figure 1 As shown, a delivery pipe 2 is connected to the pump chamber 1. Multiple pump bodies 3 are installed inside the pump chamber 1, and each pump body 3 is equipped with a suction pipe. The multiple suction pipes are connected to the delivery pipe 2, so that the liquid drawn by the pump body 3 flows into the delivery pipe 2 and is transported to the next stage through the delivery pipe 2. Specifically, by working together with multiple pumps, the speed and efficiency of liquid transfer are significantly improved. The system design avoids the bottleneck problem of traditional series systems. By using a parallel system, the overall performance is optimized, the structure is compact, and it is suitable for the efficient transfer of ultra-large flow rates of liquid.

[0027] As a preferred option, such as Figure 2 As shown, a guide fixing plate 4 is provided in the pump chamber 1 to evenly distribute multiple pump bodies 3, thereby avoiding the problem of excessively fast or slow local flow rates caused by uneven distribution of pump bodies 3.

[0028] Preferably, the guide fixing plate 4 includes a central fixing port 401 and a peripheral fixing port 402 for placing the pump body 3. A positioning hole 403 is provided next to the peripheral fixing port 402. Removable positioning rods 404 are evenly distributed around the central fixing port 401. The positioning rods 404 match the positioning holes 403. The design of the positioning rods 404 and the positioning holes 403 facilitates the quick installation and adjustment of the pump body 3.

[0029] Preferably, the peripheral fixing port 402 includes a first positioning port 100, a second positioning port 200, a third positioning port 300, and a fourth positioning port 400. The distances from the first positioning port 100, the second positioning port 200, the third positioning port 300, and the fourth positioning port 400 to the central fixing port 401 are the same. Each of the first positioning port 100, the second positioning port 200, the third positioning port 300, and the fourth positioning port 400 is provided with a positioning hole 403 for the insertion of a positioning rod 404. The line connecting the first positioning port 100 and the third positioning port 300 is perpendicular to the line connecting the second positioning port 200 and the fourth positioning port 400. The design of the four symmetrical positioning ports further optimizes the uniform distribution of the pump body 3, enabling a parallel system of four or five pumps, and improving the stability and transmission efficiency of the system.

[0030] Preferably, the system also includes a fifth positioning port 500, a sixth positioning port 600, a seventh positioning port 700, and an eighth positioning port 800. The distances from the first positioning port 100, the fifth positioning port 500, and the sixth positioning port 600 to the central fixing port 401 are the same. Positioning holes 403 for inserting positioning rods 404 are provided next to the first positioning port 100, the seventh positioning port 700, and the eighth positioning port 800. The angle between the lines connecting the first positioning port 100, the fifth positioning port 500, and the sixth positioning port 600 to the central fixing port 401 is 120 degrees. The distances from the third positioning port 300, the seventh positioning port 700, and the eighth positioning port 800 to the central fixing port 401 are also 120 degrees. The distances are the same. Positioning holes 403 for the insertion of positioning rods 404 are provided next to the third positioning port 300, the seventh positioning port 700 and the eighth positioning port 800. The angle between the lines connecting the third positioning port 300, the seventh positioning port 700 and the eighth positioning port 800 to the central fixing port 401 is 120 degrees. Specifically, by adding more positioning ports, the arrangement density of pump body 3 is further optimized, and a parallel system of three pumps and four pumps can be realized. At the same time, in conjunction with the first positioning port 100, the second positioning port 200, the third positioning port 300 and the fourth positioning port 400, a parallel system of up to nine pumps can be realized, which significantly improves the overall efficiency and stability of the system.

[0031] Preferably, each peripheral fixing port 402 is provided with an arc-shaped baffle 405 at the end away from the positioning hole 403. The arc-shaped baffle 405 is designed to prevent liquid impact or overflow, protect the pump body 3 from mechanical damage, and cooperate with the positioning rod 404 inserted into the positioning hole 403. The arc-shaped baffle 405 and the positioning rod 404 guide and fix the pump body 3, making it easy to install the pump body 3.

[0032] As a preferred option, such as Figure 3 As shown, the positioning rod 404 includes a first positioning rod group 4041 and a second positioning rod group 4042. The top of the positioning rod 404 in the first positioning rod group 4041 is engraved with a first identifier, and the top of the second positioning rod group 4042 is engraved with a second identifier. This design of different identifiers facilitates the differentiation of different positioning rod groups, enabling personnel to quickly install and adjust the pump body 3, and reducing the possibility of assembly errors. In a specific embodiment, as shown... Figure 3 As shown, the top of the first positioning rod group 4041 is marked with 90 degrees, and the top of the second positioning rod group 4042 is marked with 120 degrees. When four pumps are used, four first positioning rod groups 4041 can be selected to position the four pump bodies 3. Alternatively, two 120-degree and one 90-degree groups can be selected to form three 120-degree angles, so that three pump bodies 3 are arranged around the perimeter and one pump body 3 is arranged in the center.

[0033] Meanwhile, it is understandable that the detachable positioning rods 404 evenly distributed around the central fixing port 401 also guide and fix the pump body 3 installed in the central fixing port 401.

[0034] As a preferred option, such as Figure 1 As shown, a manhole cover 5 is provided on the infusion tube 2 to facilitate the connection with a standard manhole.

[0035] Preferably, the pump chamber 1 is connected to a conduit 6 for wiring, and the conduit 6 is connected to the explosion-proof junction box 7 above the manhole cover 5.

[0036] Preferably, a filter hole cover 8 is provided at the bottom of the pump chamber 1. The filter hole cover 8 can prevent debris from entering the pump chamber 1 and protect the pump body 3 from blockage or damage.

[0037] This invention effectively solves the problems of slow speed and low efficiency in traditional liquid transfer systems. By using a parallel system of combined explosion-proof submersible pumps, it not only improves the speed and efficiency of transferring ultra-large flow flammable and explosive liquids, but also takes into account the stability and safety of the system.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
