[0031] In response to the deficiencies or one of the deficiencies proposed in the above background art, an underwater electromagnet structure is provided in an embodiment of the present application, which can achieve the fixed connection between the electromagnet housing and the sealing cover without using welding.

[0032] See Figure 1 and Figure 2 As shown, an underwater electromagnet structure is provided in an embodiment of the present application, including:

[0033] The housing assembly includes a housing 1 with an open end, and a sealing cover 2 that is sealingly adapted to the housing 1 and encloses to form a cavity 3.

[0034] The electromagnet assembly includes a coil winding 4 disposed in the cavity 3, and an iron core 5 that penetrates the sealing cover 2 and passes through the coil winding 4. One end of the iron core 5 axially abuts against the sealing cover 2, and the other end is fixedly connected to the housing 1 to tightly fix the sealing cover 2 on the housing 1.

[0035] In the housing assembly of the underwater electromagnet structure according to the embodiment of the present application, the housing 1 and the sealing cover 2 are provided. The housing 1 and the sealing cover 2 can enclose to form a cavity 3 for installing the coil winding 4. When the coil winding 4 of the electromagnet assembly is installed into the cavity 3, the installation iron core 5 penetrates the sealing cover 2 and the coil winding 4. One end of the iron core 5 axially abuts against the sealing cover 2, and the other end is fixedly installed with the housing 1, so that the sealing cover 2 can be tightly fixed on the housing 1, realizing the fixed connection between the housing 1 and the sealing cover 2.

[0036] Exemplarily, a threaded groove can be provided on the housing 1, and the iron core 5 is threadedly connected to the housing 1 to tightly fix the sealing cover 2 on the housing 1. Compared with the prior art, it is not necessary to use welding to fix the sealing cover 2, avoiding the related problems brought by welding, and at the same time improving the installation convenience. It should be noted that the iron core 5 in this embodiment can not only cooperate with the coil winding 4 for magnetic conduction, but also act as a pull rod to lock the sealing cover 2.

[0037] In some alternative embodiments: Refer to Figure 1 and Figure 2 As shown, the embodiment of the present application provides an underwater electromagnet structure. One end of the iron core 5 of the underwater electromagnet structure away from the sealing cover 2 penetrates the housing 1, and a locking member 6 that abuts against the housing 1 is connected to the end of the iron core 5 penetrating the housing 1.

[0038] One end of the iron core 5 of the embodiment of the present application away from the sealing cover 2 penetrates the housing 1, and a locking member 6 that abuts against the housing 1 is connected to the end of the iron core 5 penetrating the housing 1. The locking member 6 can tighten the sealing cover 2 through the iron core 5, so that the sealing cover 2 is fixed on the housing 1, realizing the sealed connection between the housing 1 and the sealing cover 2.

When using a bolt, the bolt is threadedly connected to the end of the iron core 5 penetrating the housing 1 and abuts against the housing 1 to tighten the iron core 5; when using a cam-type locking rod, the cam end of the cam-type locking rod is hinged to the end of the iron core 5 penetrating the housing 1 through a hinge shaft, and the cam-type locking rod is rotated, and the cam end is used to abut tightly against the housing 1 to tighten the iron core 5.

[0040] In some alternative embodiments: Refer to Figure 1 and Figure 2As shown in the figure, an embodiment of the present application provides an underwater electromagnet structure. The locking member 6 of the underwater electromagnet structure is rod-shaped. One end of the locking member 6 is provided with an internal thread groove 61 that cooperates with the iron core 5, and a sealing member that abuts and seals against the housing 1.

[0041] The locking member 6 of the embodiment of the present application is rod-shaped. An internal thread groove 61 that can wrap the end of the iron core 5 is provided at one end of the locking member 6. When the iron core 5 passes through one end of the housing 1 and is threadedly connected to the internal thread groove 61 on the locking member 6, the end of the locking member 6 abuts against the housing 1 to tighten the iron core 5. Further, a sealing member is axially abutted between the locking member 6 and the housing 1, which can prevent the part of the housing 1 penetrated by the iron core 5 from being exposed, ensuring the sealing performance. Exemplarily, the sealing member is an O-ring, and the O-ring is embedded in the end face of the locking member 6 and surrounds the internal thread groove 61.

[0042] In some alternative embodiments: Refer to Figure 1 and Figure 2 As shown in the figure, an embodiment of the present application provides an underwater electromagnet structure. A wire is connected to the coil winding 4 of the underwater electromagnet structure. A first channel 51 for the power wire to pass through is provided on the iron core 5, and a second channel 62 that communicates with the first channel 51 and allows the power wire to pass through is provided on the locking member 6.

[0043] A first channel 51 communicating with the cavity 3 is provided on the iron core 5 of the embodiment of the present application, and a second channel 62 communicating with the first channel 51 is provided on the locking member 6. The wire connecting the coil winding 4 can pass through the first channel 51 and the second channel 62 to connect to an external power source. Exemplarily, the locking member 6 in this embodiment is a rod with an internal thread groove 61 at its end and is coaxially arranged with the iron core 5. The first channel 51 communicates with the second channel 62 through the internal thread groove 61, facilitating the wire to pass through.

The wire passes through the connecting pipe 8 and is electrically connected to the watertight plug 7. The connecting pipe 8 can withstand tension and play a role in protecting the wire.

The connecting pipe 8 of the underwater electromagnet structure is a flexible pipe, and the inside of the connecting pipe 8 is filled with oil liquid that fills the first channel 51, the second channel 62, and the cavity 3.

[0047] The connecting pipe 8 in the embodiment of the present application is a flexible pipe, and the flexible pipe is filled with hydraulic oil. The hydraulic oil fills the first channel 51, the second channel 62, and the cavity 3 accommodating the coil winding 4. During underwater operation, after the housing 1 is subjected to water pressure, the hydraulic oil in the housing 1 can flow into the flexible pipe through the first channel 51 and the second channel 62, and the flexible pipe undergoes a slight expansion deformation to accommodate more hydraulic oil, so as to achieve pressure relief and balance the pressure difference inside and outside the housing 1.

[0048] That is, it can well balance the pressure difference inside and outside the electromagnet and increase the service life of the electromagnet. Exemplarily, the connecting pipe 8 can adopt a high-pressure flexible pipe, and the high-pressure flexible pipe is a flexible pipe that can withstand high pressure. The hydraulic oil can adopt insulating oil.

At the same time, further, a sealing member for improving the sealing performance is provided between the sealing cover 2 and the housing 1. In this embodiment, the sealing member adopts an annular sealing ring and is embedded on the side wall of the sealing cover 2 to cooperate with the housing 1 to form a radial seal.
