Description

Technical Field

[0001] This application relates to the field of underwater unmanned submersible technology, specifically to a mechanical dynamic seal automatic wetting device. Background Technology

[0002] Some underwater vehicles are equipped with rotating mechanisms, and the sealing of these mechanisms is crucial during operation. Therefore, some rotating mechanisms employ mechanical dynamic sealing mechanisms 23 (such as mechanical dynamic sealing structures 23). Figure 9 As shown, the moving ring 24 and stationary ring 25 of the mechanical dynamic seal will not generate heat through friction when in water. However, when the rotating mechanism is being adjusted on land, the contact surfaces of the moving ring 24 and stationary ring 25 of the mechanical dynamic seal may generate heat through friction, which may lead to deformation and seal failure. To prevent this from happening, the dynamic seal of the rotating mechanism needs to be wetted with water.

[0003] Currently, the immersion method is mainly accomplished manually: a silicone tube is inserted into a modified water bottle. During debugging, after receiving verbal instructions from the control panel operator, one person holds the water bottle and squeezes it to pour water into the gap of the dynamic seal contact surface, while another person places a small basin under the product to catch the dripping water. Although this method is simple, it has the following problems:

[0004] 1. Manual operation is prone to human error. Watering may not start in time before the propulsion shaft rotates, or watering may continue after the propulsion shaft has finished moving. Such non-standard operation seriously affects the debugging efficiency and sealing effect.

[0005] 2. The current immersion operation requires one person to hold up the water bottle and squeeze it to pour water, while another person catches the flowing water. The operation consumes a lot of manpower and cannot guarantee continuous and stable immersion, which affects the overall debugging progress and reduces work efficiency.

[0006] 3. When manually collecting water, improper placement of the small basin or a small contact surface can easily lead to serious water spillage and waste of water resources.

[0007] Therefore, it is necessary to develop an immersion device that can effectively solve the problems of existing immersion methods, improve the commissioning efficiency and sealing performance of submersibles, and reduce labor costs. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a mechanical automatic impregnation device for dynamic seals. It utilizes a water tank fixedly mounted on the vehicle frame to store impregnation water. A water pump draws water from the tank and delivers it to the dynamic seal structure via an impregnation pipe. Dripping water is collected back into the tank via a water receiving plate, forming a circulating water supply. This achieves automatic impregnation according to the commissioning process, saving manpower, improving efficiency, and ensuring the reliability of the dynamic seal.

[0009] Specifically, this utility model provides a mechanical dynamic seal automatic impregnation device, including a vehicle frame; a water tank is fixedly installed on the vehicle frame for storing impregnation water for the dynamic seal; a water receiving component is installed on the water tank for collecting the water dripping from the dynamic seal impregnation and forming a circulating water supply; a water pump is installed in the water tank for pumping water; an impregnation water pipe is installed on the water pump for transporting the water pumped by the water pump to the dynamic seal impregnation hole of the submersible to realize the impregnation work of the dynamic seal; the water pump is connected to a power supply control cable, which connects the impregnation device to the control console, and the control console powers the impregnation device to start it.

[0010] Furthermore, the water receiving component includes: a water receiving plate, a hinge, a water receiving plate bolt, a water receiving plate nut, a hinge fixing bolt, a hinge fixing nut, and a hinge pin; two water receiving plates are provided, which are respectively installed on both sides of the water tank by hinges to catch water dripping from the dynamic seal; the hinge is connected to the water receiving plate by the water receiving plate bolt and the water receiving plate nut; the hinge is installed on the side plate of the water tank by the hinge fixing bolt and the hinge fixing nut; the hinge and the hinge are connected by the hinge pin, and the hinge and the water receiving plate rotate around the hinge pin.

[0011] Furthermore, the hinge and the water receiving plate are set as inclined surfaces. When the hinge and the water receiving plate rotate to contact the inclined surface of the hinge, the inclined surface of the hinge will support the water receiving plate, so that the water receiving plate and the water tank form an inclined surface. The lower part of the water receiving plate is connected to the water tank, so that the water dripping from the dynamic seal flows into the water tank along the water receiving plate to form a circulating water supply.

[0012] Furthermore, the water pump is directly installed inside the water tank via its own suction cup.

[0013] Furthermore, casters are installed at the bottom of the vehicle frame for moving the immersion device.

[0014] Furthermore, handles are installed on the rear end face, left end face, and right end face of the water tank to facilitate the movement of the pushing device, and the front end face of the water tank is connected to the rear end face of the rear section seat of the large docking vehicle.

[0015] Furthermore, the bottom of the water tank is provided with an opening, in which a ball valve and a water outlet pipe are installed; a drain switch is installed on the water outlet pipe. Rotating the drain switch opens the ball valve, causing the water in the water tank to be discharged through the water outlet pipe.

[0016] Furthermore, the water receiving plate is provided with ear plates for easy opening and closing.

[0017] Furthermore, the water tank is provided with a slot that matches the ear plate, so that when the water receiving plate is closed, the ear...

[0018] Working principle: When the mechanical dynamic seal automatic immersion device is working, firstly, turn the drain switch 19 to close the ball valve 7 in the water tank 4, and add the amount of water required for the immersion work to the water tank 4; place the ear plate 21 on the water receiving plate 5 into the slot 22 on the water tank 4, close the water receiving plate 5, and push the handle 17 of the water tank 4 to push the immersion device into the guide rails of the large section docking car through the caster 1, ensuring that the front face of the water tank 4 is in contact with the rear end face of the rear section seat of the large section docking car; insert the immersion water pipe 14 into the dynamic seal groove, rotate and lift the ear plate 21 placed in the slot 22 on the water tank 4, open the water receiving plate 5, and rotate the water receiving plate 5. When the hinge 10 is contacted, its inclined surface supports the water receiving plate 5, forming an inclined surface with the water tank 4. The power control cable 6 is then connected to the control console, which, through a pre-set debugging program, supplies power to the water pump 13. Once started, the water pump 13 begins drawing water from the water tank 4 and transporting it through the immersion pipe 14 to the dynamic seal immersion hole of the submersible, thus immersing the dynamic seal. Water dripping during immersion either falls directly into the water tank 4 or is caught by the water receiving plate 5. Water collected by the water receiving plate 5 flows downstream through its inclined surface into the water tank 4, creating a circulating water supply to ensure continuous immersion. After immersion, the control console stops supplying power, the water pump 13 stops running, the power control cable 6 is disconnected from the control console, the immersion device is pushed to the drainage area, and the drain switch 19 is turned to open the ball valve 7 in the water tank 4. The water in the water tank 4 is then discharged through the outlet pipe 20.

[0019] Beneficial effects:

[0020] 1. This utility model collects the water dripping from the dynamic seal into a water tank through a water receiving component. The water receiving component and the water pump work together to form a circulating water supply system, which not only saves water resources but also ensures a continuous supply of water for the dynamic seal wetting and improves wetting efficiency.

[0021] 2. This utility model connects to the control console via a power supply control cable, enabling remote start-up and control, which improves the convenience of operation and the stability of the immersion process.

[0022] 3. This utility model has casters at the bottom of the water tank to facilitate the movement of the entire immersion device; handles are installed on the rear, left, and right ends of the water tank to make it easier to push the device.

[0023] 4. This utility model has an ear plate on the water receiving plate, which makes it easy to open and close the water receiving plate. At the same time, the water tank has a slot that matches the ear plate. When the water receiving plate is closed, the ear plate rests on the slot, which prevents the water in the water tank from shaking and splashing out during the movement of the immersion device.

[0024] 5. The water pump of this utility model can be directly installed into the inside of the water tank through its own suction cup. This design simplifies the installation process, reduces the use of external connecting parts, and lowers the failure rate.

[0039] like Figure 1 , 6 As shown, the vehicle frame 2 is made of aluminum profiles of different specifications and connected by aluminum profile corner fittings to form the aluminum profile vehicle frame 2. Casters 1 are installed at the bottom of the vehicle frame 2 for moving the immersion device. The water tank 4 is fixedly installed on the vehicle frame 2 by water tank fixing bolts 3 for storing dynamic seal immersion water.

[0040] like Figure 4 As shown, two water receiving plates 5 are provided, respectively installed on both sides of the water tank 4 via hinges 8, to catch water dripping from the dynamic seal. The hinges 8 are connected to the water receiving plates 5 via water receiving plate bolts 9 and water receiving plate nuts 15. The hinges 10 are installed on the side plate of the water tank 4 via hinge fixing bolts 11 and hinge fixing nuts 16. The hinges 8 and hinges 10 are connected by hinge pins 12, and the hinges 8 and water receiving plates 5 rotate around the hinge pins 12. The opposite surfaces of the hinges 10 and the water receiving plates 5 are set as inclined surfaces. When the hinges 8 and the water receiving plates 5 rotate to contact the inclined surfaces of the hinges 10, the inclined surfaces of the hinges 10 will support the water receiving plates 5, so that the water receiving plates 5 and the water tank 4 form an inclined surface. The lower part of the water receiving plates 5 is connected to the water tank 4, so that the water dripping from the dynamic seal flows into the water tank 4 along the water receiving plates 5, which is used to collect the water dripping from the dynamic seal into the water tank 4, forming a circulating water supply.

[0041] like Figure 1 As shown, the ear plate 21 is set on the water receiving plate 5 to facilitate opening and closing of the water receiving plate 5. The slot 22 set on the water tank 4 matches the ear plate 21. When the water receiving plate 5 is closed, the ear plate 21 rests on the slot 22 to prevent the water in the water tank 4 from sloshing out during the movement of the immersion device.

[0042] like Figure 1As shown, the water pump 13 is directly installed inside the water tank 4 via its own suction cup for pumping water; the water pump 13 is equipped with a wetting water pipe 14 for transporting the water pumped by the water pump 13 to the wetting hole of the dynamic seal of the submersible to achieve the wetting work of the dynamic seal; the water pump 13 is connected to a power control cable 6, which connects the wetting device to the control console, and the wetting device is started by powering the control console.

[0043] like Figure 1 As shown, handles 17 are welded to the rear end face, left end face, and right end face of water tank 4 to facilitate the movement of the pushing device. The front end face of water tank 4 is connected to the rear end face of the rear section seat of the large docking car.

[0044] like Figure 3 As shown, the ball valve 7 and the outlet pipe 20 are installed in the opening 18 at the bottom of the water tank 4; the drain switch 19 is installed on the outlet pipe 20. Rotating the drain switch 19 opens the ball valve 7, which in turn opens the water in the water tank 4 and discharges the water through the outlet pipe 20.

[0045] like Figure 7 , 8 As shown, during use, first, turn the drain switch 19 to close the ball valve 7 in the water tank 4, and add the amount of water required for the immersion work to the water tank 4; place the ear plate 21 on the water receiving plate 5 into the slot 22 on the water tank 4, and close the water receiving plate 5 to prevent the water in the water tank 4 from splashing out during the movement of the immersion device; push the handle 17 of the water tank 4 to push the immersion device into the guide rails of the large section docking car through the caster 1, ensuring that the front face of the water tank 4 is in contact with the rear face of the rear section seat of the large section docking car; insert the immersion water pipe 14 into the dynamic sealing groove 26, rotate and lift the ear plate 21 placed in the slot 22 on the water tank 4, open the water receiving plate 5, and rotate the water receiving plate 5 to contact the inclined surface of the hinge 10, which will support the water receiving plate. 5. At this time, the water receiving plate 5 and the water tank 4 form an inclined plane; and the power supply control cable 6 is connected to the control console. The control console controls the power supply to the water pump 13 through the preset debugging program. After the water pump 13 starts, it begins to draw water from the water tank 4 and delivers the water to the mechanical dynamic seal mechanism 23 of the submersible through the immersion water pipe 14 to realize the immersion work of the mechanical dynamic seal mechanism 23. The water flows from the dynamic seal immersion hole to the contact end face of the dynamic ring 24 and the stationary ring 25 and flows out from the bottom. The dripping water falls directly into the water tank 4 or is caught by the water receiving plate 5. The water caught by the water receiving plate 5 flows into the water tank 4 through the inclined plane of the water receiving plate 5, and is then drawn by the water pump 13 and sent to the mechanical dynamic seal mechanism 23 to form a circulating water supply to ensure continuous immersion. After soaking is complete, the control panel is powered off, the water pump 13 stops running, the power control cable 6 is disconnected from the control panel, the soaking device is pushed to the drainage site, the drain switch 19 is turned to open the ball valve 7 in the water tank 4, and the water in the water tank 4 is discharged through the outlet pipe 20.
