[0024] See also Figure 1-Figure 3 The present invention provides an automatic dispensing device for grease, comprising a watertight box 2 with an opening facing upward, a cover plate 1 (made of titanium alloy) and a hydraulic valve block 3, wherein an installation space is provided in the watertight box 2, the cover plate is sealed and covered on the opening of the watertight box 2, and the hydraulic valve block 3 is installed in the installation space;

[0025] The cover plate 1 is provided with an input interface 4 and multiple output interfaces 5; the hydraulic valve block 3 is provided with an oil inlet and multiple oil outlets; in the installation space, the oil inlet is connected to the input interface 4, the number of the oil outlets is equal to the number of the output interfaces 5, and the multiple oil outlets are connected one by one to the multiple output interfaces 5.

[0027] The outer peripheral wall of the first connection block 11 is sealed to the side wall of the installation space via a first sealing ring 13 , and the second connection block 12 is connected to the end surface of the watertight box 2 via a second sealing ring 14 .

[0028] Preferably, it further comprises an electrically insulating cabin penetration connector, and one of the electrically insulating cabin penetration connectors is connected to each of the input interface 4 and the output interface 5 , and the inner side of the cabin penetration connector is used to connect to the hydraulic valve block 3 .

[0029] Preferably, the electrically insulating cabin penetration joint includes an internal threaded joint and an external threaded joint, the internal threaded joint and the external threaded joint are connected to each other, the internal threaded joint is located on the inner side of the cover plate 1, and the external threaded joint is located on the outer side of the cover plate 1, the internal threaded joint and the cover plate 1 are sealed by a polytetrafluoroethylene gasket, and the external threaded structure and the cover plate 1 are sealed by a polytetrafluoroethylene gasket.

[0030] Preferably, it also includes an electric lubrication pump, which is connected to the electrically insulating through-cabin connector on the input interface 4 through a pipeline.

[0031] Preferably, the number of the output interfaces 5 is 10, the number of the hydraulic valve blocks 3 is 5, and each of the hydraulic valve blocks 3 has 2 oil outlets.

[0032] The grease storage electric lubrication pump (grease storage capacity 2L) in the present invention is only 279×257×357mm in size, which is more compact than the electric lubrication pumps sold on the market and is suitable for environments with strict space requirements such as submarines; the power supply is 24V power supply, and the load drive is extremely small, which prolongs the service life of the electric lubrication pump; the air noise during the operation of the electric lubrication pump is less than 55db after inspection; the working environment temperature can reach -40℃~70℃, and it can adapt to the salt spray environment; the electric lubrication pump has stable oil output and the grease output is not less than 4cm3 / min. The electric lubrication pump has a low liquid level alarm function. When the grease in the oil storage tank is lower than the set oil volume, a low liquid level alarm signal can be issued to remind personnel to replenish the oil storage tank in time.

[0033] The automatic distribution assembly of the present invention is designed with a titanium alloy watertight box 2 to assemble the hydraulic valve block 3 therein, and adopts two seals, end face seal and radial seal, to ensure that the automatic distribution assembly can withstand 6.75MPa seawater external pressure and long-term seawater corrosion. The sealing diagram is shown in FIG. Figure 1 The watertight box 2 is made of titanium alloy material as a whole, not welded, thus ensuring the strength of the titanium alloy watertight box 2 and being more adaptable to the use environment of deep sea.

[0034] The size of the automatic distribution component is 366×366×272mm, and it is composed of 5 hydraulic valve blocks 3. Each hydraulic valve block 3 has 2 oil outlets, so the automatic distribution component has a total of 10 oil outlets, so that the automatic distribution component can lubricate 10 lubrication points at the same time. The automatic distribution component supplies oil accurately, and the displacement of each oil outlet per cycle is 0.48cm 3 (The error does not exceed 20%).

[0035] The oil inlet and outlet are equipped with an electrically insulating through-tank joint, which consists of an internal threaded joint, an external threaded joint and an external pipe cap. The electrically insulating through-tank joint is connected to the hydraulic valve block 3 through an internal pipeline, so that it has the insulation performance required for electrical corrosion protection. The pipeline layout is centered on the progressive distributor, first arranged radially outward, and then connected to the output interface 5 on the cover of the watertight box 2 from an appropriate position. The through-tank joint ensures the watertightness of the grease oil circuit when it passes through the watertight box 2. On both sides of the cover plate 1, it is watertight by enhancing the polytetrafluoroethylene gasket structure. The contact surface between the joint and the cover of the watertight box 2 is watertight by another O-ring. Under the protection of three sealing rings and two sealing forms, the watertightness of the through-tank joint and the cover of the watertight box 2 is ensured. Since the material of the external pipeline is different from that of the watertight box 2, in order to avoid electrochemical corrosion, an insulating material is used to separate the external pipeline and the output joint of the watertight box to ensure that there is no contact between the two dissimilar metals. The structure of the electrically insulating through-tank joint is as follows Figure 2 shown.

[0036] The main working principle of the automatic grease distribution device is as follows: each set of automatic grease distribution device contains 41 grease input interfaces and 510 grease output interfaces. The output end of the electric lubrication pump is connected to the grease input interface 4 of the automatic lubricating oil distribution device through the oil pipeline. The grease input interface 4 is connected to the internal pipeline of the watertight box 2 through the through-tank joint and connected to the input end of the progressive distributor. The output end of the progressive distributor is connected to the grease output interface 5 of the automatic lubricating oil distribution component through the internal pipeline and the through-tank joint, and is connected to each lubrication point through the external pipeline.

[0037] The operating steps of the automatic grease dispensing device are as follows:

[0038] The automatic distribution assembly is installed at a fixed installation position outside the submarine cabin and connected with an external pipeline extending to the lubrication point;

[0039] The electric lubrication pump is installed at a fixed installation position in the submarine cabin, and the oil outlet of the electric lubrication pump is connected to the oil inlet of the automatic distribution component through an oil pipeline;

[0040] Refill the grease storage tank of the electric lubrication pump;

[0041] Connect the electric lubrication pump power line and the liquid level alarm signal line (the electric lubrication power supply is 24V DC, and it works as soon as it is powered).

[0042] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will all be included in the scope of the claims of the present invention.
