It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, a solenoid valve box for a marine hydraulic control system includes a box body 1, a pipe assembly 6 and a terminal block 2 located within the box body 1, an oil inlet pipe 7 located at the upper end of the pipe assembly 6, a solenoid valve group 8 located within the box body 1 and connected to the terminal block 2 via a power distribution line, and a plurality of oil discharge branches 9 located at the output end of the solenoid valve group 8. It also includes a flow guide assembly 4 located on the oil inlet pipe 7 and used to control the flow direction of the hydraulic oil in the oil inlet pipe 7, a cooling assembly 3 wrapped around the outer surface of the oil inlet pipe 7 and used to heat exchange and cool the hydraulic oil in the oil inlet pipe 7, and a heat dissipation assembly 5 located on the outer wall of the box body 1 and used to cool the cooling water in the cooling assembly 3 and dissipate heat from the solenoid valve group 8.

[0031] Among them, a plurality of oil discharge branch pipes 9 are provided with pressure transmitters 10 .

[0032] like Figure 3 and Figure 4As shown, a plurality of oil drain branch pipes 9 are provided with a waterproof joint 11 at one end away from the solenoid valve group 8, and the waterproof joint 11 is located outside the box body 1; the cooling component 3 includes a heat exchange coil 37 wrapped around the outer surface of the oil inlet pipe 7, a water inlet pipe 32 at one end of the heat exchange coil 37, a water outlet pipe 33 at the other end of the heat exchange coil 37, a return water tank 31 at the side of the outlet pipe 33 away from the heat exchange coil 37, a return water pipe 34 communicating with the return water tank 31, a water collecting tank 36 at the end of the return water pipe 34 away from the return water tank 31, and a drain pipe 35 on the water collecting tank 36; wherein the return water tank 31 and the water collecting tank 36 are both located on the outer wall of the box body 1, and the water collecting tank 36 is an upper open structure; the flow guide component 4 includes a No. 1 conduit 41 on the oil inlet pipe 7, a temperature control valve 43 on the No. 1 conduit 41, a No. 2 conduit 42 and a No. 3 conduit 44 at the output end of the temperature control valve 43, and a No. 43 conduit 44 at the output end of the temperature control valve 43. A one-way valve 47 is provided on the No. 2 conduit 42; wherein, the side of the No. 3 conduit 44 away from the temperature control valve 43 is connected to the input end of the solenoid valve group 8, and the side of the No. 2 conduit 42 away from the temperature control valve 43 is connected to the oil inlet pipe 7; the No. 3 conduit 44 is an L-shaped structure, and the No. 1 corrugated telescopic tube 45 distributed longitudinally and the No. 2 corrugated telescopic tube 46 distributed transversely are respectively provided on the No. 3 conduit 44. The arrangement of the No. 1 corrugated telescopic tube 45 and the No. 2 corrugated telescopic tube 46 can reduce the influence of the pressure oscillation or impact force of the pipeline assembly 6 on the solenoid valve group 8. The return pipe 34 is provided with a water pump placed in the return tank 31. When the temperature of the oil passing through the No. 1 conduit 41 is high, the temperature control valve 43 controls the hydraulic oil to be discharged from the No. 2 conduit 42 and transported to the oil inlet pipe 7 again for a secondary cooling operation, so as to avoid the coil in the solenoid valve group 8 from being burned due to the excessive temperature of the hydraulic oil passing through the solenoid valve group 8.

[0033] like Figure 5 、 Figure 6 and Figure 7As shown, the heat dissipation component 5 includes a fan member 51 placed inside the box body 1, a sealing ring 53 sleeved on the fan member 51, a heat dissipation member 52 located on one side of the sealing ring 53 and used to drive the fan member 51 to rotate and cool the cooling water in the cooling component 3, and a plurality of heat dissipation fins 54 located on the heat dissipation member 52; the heat dissipation member 52 includes a cylindrical barrel 521 connected to the water inlet pipe 32, a rotating shaft 523 located inside the cylindrical barrel 521 and connected to the fan member 51, a plurality of partitions 522 located on the outer surface of the rotating shaft 523, and a water pipe 524 located on the cylindrical barrel 521 and connected to the water collecting tank 36; a plurality of guide plates 525 are provided on the plurality of partitions 522, and the plurality of guide plates 525 are all away from the rotating shaft. One side of 523 is inclined, and a plurality of water outlet holes 526 are opened at the lower end of the water pipe 524. The side of the partition 522 away from the rotating shaft 523 is in contact with the inner wall of the cylindrical barrel 521. The rotating shaft 523 rotates under the action of the partition 522 with water, thereby driving the fan part 51 to rotate synchronously to perform heat dissipation operation on the solenoid valve group 8. As the partition 522 continues to rotate, the water enters the water inlet pipe 32 for the next heat exchange and cooling operation. The water outlet holes 526 set in the water pipe 524 can increase the contact area between the water and the air, thereby improving the cooling effect of the water. The guide plate 525 provided on the partition 522 can increase the contact area between the water and the air while extending the flow path of the water.

[0034] It should be noted that the present invention is a solenoid valve box for a marine hydraulic control system. When the solenoid valve box for a marine hydraulic control system needs to be used, the pipeline assembly 6 transports the hydraulic oil to the oil inlet pipe 7. During the transportation process, the cooling water in the cooling assembly 3 is transported to the heat exchange coil 37 through the water inlet pipe 32. The cooling water in the heat exchange coil 37 and the oil in the oil inlet pipe 7 perform heat exchange. The oil after heat exchange is transported to the temperature control valve 43 through the No. 1 conduit 41. The cooled oil is transported to the No. 3 conduit 44 through the temperature control valve 43, and the oil output of each oil circuit in the oil drain branch pipe 9 is realized through the solenoid valve group 8. When the temperature of the oil passing through the No. 1 conduit 41 is high, the temperature control valve 43 controls the hydraulic oil to be discharged from the No. 2 conduit 42 and transported to the oil inlet pipe 7 again for a secondary cooling operation, so as to avoid the coil in the solenoid valve group 8 from burning due to the excessive temperature of the hydraulic oil passing through the solenoid valve group 8. The high-temperature water after heat exchange is transported to the heat dissipation component 5 through the return water tank 31, the return water pipe 34, and the water collecting tank 36. The water enters the cylindrical barrel 521 through the water delivery pipe 524 and falls to the partition 522 below under the action of its own gravity. At this time, the rotating shaft 523 rotates under the action of the partition 522 with water, thereby driving the fan component 51 to rotate synchronously to perform heat dissipation operation on the solenoid valve group 8. As the partition 522 continues to rotate, the water enters the water inlet pipe 32 for the next heat exchange and cooling operation. The water outlet hole 526 provided in the water delivery pipe 524 can increase the contact area between the water and the air, thereby improving the cooling effect of the water. The guide plate 525 provided on the partition 522 can extend the flow path of the water while increasing the contact area between the water and the air, thereby further improving the cooling effect of the water, which is conducive to the cooling water being quickly put into use for cooling the hydraulic oil.
