[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. The present utility model provides a high-pressure solenoid valve device for underwater use. The high-pressure solenoid valve device for underwater use includes a solenoid valve sealing box, which has a simple overall structure and reasonable design. A first box cover and a second box cover are respectively fixed at two ends of the solenoid valve sealing box, and first grooves in a shape of a Chinese character "kou" (square) are respectively arranged at the two ends of the solenoid valve sealing box.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0023] Please see Figure 1 This utility model provides an embodiment of a high-pressure solenoid valve device for underwater use. The device includes a solenoid valve sealing housing 1, which is a hollow cavity structure with openings at both ends. A first housing cover plate 3 and a second housing cover plate 4 are fixed to both ends of the solenoid valve sealing housing 1. A ring of screw holes is provided on the first housing cover plate 3 and the second housing cover plate 4, and both are secured to the solenoid valve sealing housing 1 by a number of screws. Both ends of the valve sealing housing 1 are provided with a first groove 101 in the shape of a square. O-rings 7 are filled in both first grooves 101. The two O-rings 7 are respectively in contact with the first housing cover plate 3 and the second housing cover plate 4. By setting the two O-rings 7 in the two first grooves 101 respectively, the connection position between the solenoid valve sealing housing 1 and the first housing cover plate 3, and between the solenoid valve sealing housing 1 and the second housing cover plate 4 is sealed. In addition, a watertight cable connector 8 is installed on the first housing cover plate 3.

[0024] Please see Figure 2 The cavity contains a solenoid valve manifold 2, with a high-pressure solenoid valve 5 and a sealing pipe joint 6 installed at both ends of the solenoid valve manifold 2. The high-pressure solenoid valve 5 is located inside the cavity of the solenoid valve sealing housing 1. In actual operation, one end of the watertight cable joint 8 passes through the first housing cover plate 3 and is connected to the high-pressure solenoid valve 5, while the other end is connected to a controller. The controller is located outside the solenoid valve sealing housing 1. The structure of the controller is existing technology and will not be described in detail here. In addition, the device is easy to maintain. When the high-pressure solenoid valve 5 malfunctions, the device can be retrieved from underwater, and a new high-pressure solenoid valve 5 can be quickly replaced as if it were on land after opening the first housing cover plate 3 and the second housing cover plate 4. Maintenance is simple.

[0025] Please see Figure 3The solenoid valve manifold 2, located away from the high-pressure solenoid valve 5, has a second groove 201 in the shape of a square. The second groove 201 is filled with an O-ring seal 7. The solenoid valve manifold 2 is positioned within the cavity of the solenoid valve sealing housing 1. The O-ring seal 7 contacts and connects to the inner wall of the cavity of the solenoid valve sealing housing 1. By placing the O-ring seal 7 within the second groove 201, a seal is formed at the connection point between the solenoid valve sealing housing 1 and the solenoid valve manifold 2, thus creating a complete "sealed" environment. Regardless of the depth of the high-pressure solenoid valve 5 underwater, it remains in a stable sealed environment, thus protecting it from water immersion and corrosion. The high-pressure solenoid valve 5 only needs to perform its normal switching function, controlling the fluid flowing in and out through the sealing pipe joint 6. All the harsh underwater conditions are withstood by the three O-ring seals 7. This allows the technically mature and low-cost standard land-based solenoid valve to be used in high-pressure and highly corrosive underwater environments, avoiding the use of expensive, specially designed underwater solenoid valves and achieving lower costs.

[0026] Please see Figure 4 A mounting groove is provided through the solenoid valve sealing housing 1. The end of the solenoid valve manifold 2 near the sealing pipe joint 6 is embedded in the mounting groove. The solenoid valve manifold 2 is provided with a ring of screw holes and is locked to the solenoid valve sealing housing 1 by several screws. The entire solenoid valve manifold 2 is set in the cavity of the solenoid valve sealing housing 1, except for the end of the solenoid valve manifold 2 away from the high-pressure solenoid valve 5 which is embedded in the solenoid valve sealing housing 1. Since the solenoid valve manifold 2, the first housing cover plate 3 and the second housing cover plate 4 are all locked to the solenoid valve sealing housing 1, the device has high reliability. The structural strength and sealing form of the solenoid valve sealing housing 1 are designed according to the specific water depth and environment required for operation, and the reliability is guaranteed. The high-pressure solenoid valve 5 operates in a stable environment in the cavity of the solenoid valve sealing housing 1, and its lifespan is basically the same as when it works on land.

[0027] Please refer to it again. Figure 4 Multiple sealing pipe joints 6 are provided, and all of them are exposed on the outside of the solenoid valve sealing housing 1. In this embodiment, four sealing pipe joints 6 are provided, three of which are located at the top and arranged in a straight line, and one is located at the bottom. The sealing pipe joint 6 located at the bottom serves to connect to the external hydraulic pipe, introducing external hydraulic oil into the solenoid valve manifold 2. The solenoid valve manifold 2 is designed with independent pipes that can connect to the input ports of all high-pressure solenoid valves 5. Therefore, the hydraulic oil passes through the high-pressure solenoid valve 5, and finally flows through the solenoid valve manifold 2 and the sealing pipe joint 6 into the internal hydraulic pipe. In this process, the high-pressure solenoid valve 5 controls the external hydraulic pipe and also controls the opening and closing of the internal hydraulic pipe. The structures of the internal and external hydraulic pipes are existing technologies and will not be described in detail here.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
