[0035] Reference Figure 1and Figure 2 , a mounting plate 41 is fixed on the positioning rod 4, and a plurality of positioning rods 4 are fixedly connected to the mounting plate 41, and a plurality of positioning rods 4 are located on the same side of the mounting plate 41, and one end of the mounting plate 41 close to the positioning rod 4 fits the pump body 3, and the distribution of the positioning rod 4 on the mounting plate 41 is consistent with the distribution of the mounting hole 1 12, the mounting hole 21, and the mounting hole 3 31 on the corresponding machine body 1, the connecting frame 2, and the pump body 3. A locking member 42 is threadedly connected to the positioning rod 4, and the locking member 42 is located at one end of the machine body 1 away from the pump body 3, so that the limiting surface is pressed against one end of the pump body 3 away from the machine body 1, and then the machine body 1 and the pump body 3 are pressed against the opposite ends of the connecting frame 2 respectively, so as to position the three. In this embodiment, the locking member is a nut.

[0036] After one of the positioning rods 4 is penetrated by the mounting hole 12, the positioning rods 4 are all penetrated by the corresponding mounting hole 31, the mounting hole 21 and the mounting hole 12, and then the locking piece 42 is rotated to make the locking piece 42 press against the body 1, without penetrating the positioning rods 4 one by one, which is conducive to improving the installation efficiency.

[0037] Reference Figure 1 and Figure 3 A second guide surface 43 is formed at one end of the positioning rod 4 away from the mounting plate 41. The second guide surface 43 is gradually tapered in the direction away from the mounting plate 41. The second guide surface 43 is used to abut against the inner walls of the first mounting hole 12, the second mounting hole 21 and the third mounting hole 31, so as to facilitate the positioning rod 4 to pass through the first mounting hole 12, the second mounting hole 21 and the third mounting hole 31.

[0038] During the actual installation process, the locking piece 42 is rotated to disengage the locking piece 42 from the corresponding positioning rod 4, and several positioning rods 4 are inserted into the mounting hole three 31 from the end of the pump body 3 away from the machine body 1, and the mounting holes three 31, mounting holes two 21 and mounting holes one 12 are successively penetrated and then pass out from the mounting hole one 12, and the locking piece 42 is re-threaded on the positioning rod 4, and the locking piece 42 is rotated in the direction close to the machine body 1 so that the locking piece 42 is pressed against the end of the machine body 1 away from the mounting plate 41, so that the machine body 1, the connecting frame 2 and the pump body 3 can be fixed.

[0039] Reference Figure 3 and Figure 5 Two sealing sheets 22 are slidably connected to the connecting frame 2. The two sealing sheets 22 are located at opposite sides of the connecting frame 2. The distribution direction of the two sealing sheets 22 is parallel to the distribution direction of the machine body 1 and the pump body 3. The sliding direction of the two sealing sheets 22 is parallel to the sliding direction of the sealing sheets 22. The sealing sheets 22 slide into or out of the connecting frame 2. A positioning member 5 is installed on the connecting frame 2. The positioning member 5 is used to position the sealing sheets 22. The two sealing sheets 22 are respectively pressed against the pump body 3 and the machine body 1. The two sealing sheets 22 are respectively used to fill the gap between the connecting frame 2 and the pump body 3 and the gap between the connecting frame 2 and the machine body 1, so that seawater is not easy to erode the connection.

[0040] Reference Figure 3 and Figure 5 The positioning member 5 includes an elastic group 51 and a positioning block 52. The elastic group 51 and the positioning block 52 are both located between the two sealing sheets 22. The position and number of the elastic group 51 correspond to the position and number of the sealing sheets 22. The opposite ends of the elastic group 51 are respectively fixedly connected to the mounting frame and the corresponding sealing sheet 22. The elastic group 51 tightens the corresponding sealing sheet 22, so that the sealing sheet 22 has a tendency to move and extend into the connecting frame 2. The position and number of the positioning blocks 52 correspond to the position and number of the sealing sheets 22. The positioning blocks 52 include two blocks 521, which are located on opposite sides of the sealing sheet 22. The sliding direction of the blocks 521 is perpendicular to the rotating axis of the body 1. The blocks 521 slide close to or away from the axis of the connecting frame 2. The two blocks 521 move close to or away from each other. The blocks 521 are located on a side of the corresponding sealing sheet 22 close to the corresponding elastic group 51. The blocks 521 slide into or out of the mounting hole 21. A guide surface 5211 is formed on the block 521. The guide surface 5211 is located on a side of the block 521 close to the corresponding sealing sheet 22. The guide surface 5211 is inclined. The guide surface 5211 is inclined in the direction close to the axis of the connecting frame 2 and away from the corresponding sealing sheet 22. The guide surface 5211 is used to abut against the sealing sheet 22 so that the sealing sheet 22 moves along the guide surface and extends out of the connecting frame 2. The block 521 slides into or out of the second mounting hole 21 . When the block 521 moves into the second mounting hole 21 , there is an installation gap between the block 521 and the inner wall of the second mounting hole 21 . The positioning rod 4 is inserted into the installation gap, and the second guide surface 43 abuts against the block 521 .

[0041] The attached drawings of this embodiment mainly show the state of the seawater pump after installation, and do not show the installation gap. In this embodiment, the elastic group 51 is composed of a plurality of springs. In other embodiments, the elastic group 51 can also be composed of a plurality of connecting ropes. During installation, the sealing sheet 22 is driven by the block 521 to move and break the connecting rope.

[0042] During transportation, the positioning rod is not provided with the first, second and third mounting holes, and the sealing sheet is continuously extended into the connecting frame under the action of the elastic group, which is beneficial to protecting the sealing sheet during transportation and storage.

[0043] During the actual installation process, the positioning rod 4 is passed through the installation gap in the second installation hole 21. At this time, the positioning rod 4 abuts the part of the block 521 extending into the second installation hole 21, so that the block 521 moves toward the axis of the connecting frame 2, and the guide surface 1 5211 abuts the corresponding sealing sheet 22, so that the sealing sheet 22 moves out of the connecting frame 2, pressing against the machine body 1 and the pump body 3, reducing the gap between the pump body, the machine body and the connecting frame 2, which is beneficial to reducing the erosion of seawater on the connection between the pump body, the machine body and the connecting frame 2, and improving the sealing effect of the seawater pump.

[0044] The implementation principle of a seawater pump in an embodiment of the present application is as follows: in the actual installation process, the machine body 1, the connecting frame 2 and the pump body 3 are arranged in sequence, so that the mounting hole 12, the mounting hole 21 and the mounting hole 31 are located on the same straight line, the positioning rod 4 is sequentially passed through the mounting hole 31, the mounting hole 21 and the mounting hole 12, and passed through the machine body 1, the locking piece 42 is connected to the part of the positioning rod 4 passing through the machine body 1 through a thread, the locking piece 42 is rotated to make the locking piece 42 press against the machine body 1, the locking piece 42 and the mounting plate 41 respectively press against the ends of the machine body 1 and the pump body 3 that are away from each other, so that the machine body 1 and the pump body 3 are respectively pressed against the opposite ends of the connecting frame 2 for positioning; when the seawater pump needs to be repaired, the locking piece 42 is rotated to make the locking piece 42 disengage from the positioning rod 4, and then the positioning rod 4 is removed from the seawater pump, so that the machine body 1, the pump body 3 and the connecting frame 2 can be disassembled for repair, so that the seawater pump is convenient to disassemble and assemble, which is conducive to improving the disassembly and assembly efficiency of the seawater pump.
