Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, and in particular to a special oil drain pipe for rudder propellers. Background Technology

[0002] An oil drain pipe is a pipe or pipeline assembly used to drain liquids (especially oily substances). It is widely used in mechanical equipment, industrial systems, transportation vehicles and other fields. Its main function is to discharge oil (such as lubricating oil, hydraulic oil, fuel oil, etc.) from inside the equipment in a controlled manner for replacement, maintenance or repair.

[0003] A search revealed that the document with announcement number "CN216497937U" mentions "an intermediate oil drain pipe for an oil filter vehicle, comprising a first oil pipe, a second oil pipe that is connected and fixedly inserted through the middle of the first oil pipe and the first oil pipe and the second oil pipe are interconnected, a fixing rod that is fixedly connected to the middle of the inner wall of the rear end of the second oil pipe, a third threaded ring that is provided at the front end of the outer diameter of the second oil pipe, and a first threaded ring that is provided at the right side of the middle of the outer diameter of the first oil pipe." In use, the oil pipe is installed and fixed with bolts through the round holes provided on the mounting base to prevent oil leakage during filtration. A stainless steel filter element is provided on the outer diameter of the fixing rod. When using the pipe, the first and third sealing caps are unscrewed. Edible oil passes through the third oil pipe and then through the stainless steel filter element inside the second oil pipe for filtration. The filtered edible oil flows out through both ends of the first oil pipe. It is very convenient to use and deserves widespread promotion.

[0004] However, when changing the lubricating oil of the propeller assembly, the drain port is located at the bottom of the propeller main shaft. When draining the oil, it is necessary to open the internal clamping spring. The propeller manufacturer does not provide special tools, which makes the oil change work difficult. In addition, multiple people are needed to assist in changing the oil. Two people use wrenches to open the clamping spring, and one person uses a container to catch the oil from below. When there is wind, the oil will be blown everywhere.

[0005] Therefore, we provided a dedicated oil drain pipe for the propeller to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a special oil drain pipe for a rudder propeller, including a main pipe 1, a filter assembly 2 in the middle of the main pipe 1, the filter assembly 2 including a connecting sleeve 203 installed in the middle of the main pipe 1, a ball valve 209 installed at the bottom end of the main pipe 1, a connecting pipe 210 installed at the bottom end of the ball valve 209, and an external thread 211 welded to the bottom end of the connecting pipe 210.

[0033] Furthermore, the top outer side of the main pipe 1 is provided with a thread 201. The thread 201 is designed with reference to the rudder screw plug that needs to be drained. By machining in full accordance with the rudder screw plug standard, it is ensured that the thread 201 and the rudder screw plug can be tightened to prevent safety accidents caused by accidental loosening and draining of oil, thereby improving the safety of the device. In addition, the work scenario that previously required multiple people to work together and was time-consuming and laborious can now be easily operated by a single person, reducing labor costs and significantly improving efficiency.

[0034] Furthermore, a round iron plate 202 is welded to the inner side of the top of the main pipe 1. Half of the round iron plate 202 is welded to the inner side of the main pipe 1, and the other half protrudes from the pipe opening of the main pipe 1. The protruding round iron plate 202 can easily lift the compression spring, so that the compression spring is always in the maximum state, thereby maximizing the discharge of oil, improving the oil change speed, and increasing work efficiency. The round iron plate 202 presses on the top of the spring, evenly distributing the external pressure to the entire spring cross section, preventing the spring from tilting or deforming locally, reducing spring wear, and improving spring life.

[0035] Furthermore, a filter cake box 204 is welded to the left side of the connecting sleeve 203. A filter screen 205 is installed at the connection between the filter cake box 204 and the connecting sleeve 203. The main pipe 1 and the inside of the filter screen 205 are at a 60° angle, so that the filtered impurities can flow better into the filter cake box 204. In addition, filtering impurities and particles in the oil through the filter screen 205 can reduce the frictional wear of the ball valve 209, protect the ball valve 209, and improve the service life of the ball valve 209. The filtered oil is also convenient for users to reuse, saving costs.

[0036] Furthermore, an observation window 206 is installed on the outer surface of the filter cake box 204. The observation window 206 is made of glass. Users can observe the accumulation of impurities inside the filter cake box 204 through the transparent observation window 206 without disassembling or opening the device, and directly determine whether cleaning or replacement is needed. This avoids maintenance delays caused by not being able to see the internal condition, and also avoids frequent disassembly of the device to check the condition, reducing component wear caused by improper operation and improving the service life of the device.

[0037] Furthermore, a filter cake bottom 207 is installed at the bottom of the filter cake box 204, and a cake collection bottom cover 208 is threadedly connected to the bottom of the filter cake bottom 207. After the filtered impurities are full, the user can easily unscrew the cake collection bottom cover 208 from the filter cake bottom 207 to facilitate the user in cleaning the impurities, making the operation more convenient and improving the ease of use.

[0038] Furthermore, a hose assembly 3 is provided at the bottom end of the external thread 211. The hose assembly 3 includes a hose interface 301 threadedly connected to the bottom end of the external thread 211. A folded hose 302 is welded to the bottom end of the hose interface 301. A connection port 303 is welded to the bottom end of the folded hose 302. After folding, the volume is reduced, making it easy to store and carry. Users can quickly adjust the length of the folded hose 302 according to actual needs, improving the convenience and flexibility of operation. In addition, the folded hose 302 can collect all the oil into the oil container, preventing oil leakage.

[0039] Working principle: Place the device in the working position, remove the rudder oil drain plug, prepare an old oil container, and slowly screw the thread 201 into the drain port. The round iron plate 202 will lift the rudder's compression spring. Then open the ball valve 209. The lubricating oil flows along the main pipe 1 into the connecting sleeve 203 and is filtered by the filter screen 205. The clean lubricating oil flows along the connecting pipe 210 to the hose interface 301 connected by the external thread 211. Because the filter screen 205 is inclined, the filtered impurities flow down the slope into the filter cake box 204. The user can monitor the accumulation of impurities in the filter cake box 204 through the transparent observation window 206. If cleaning is required, unscrew the slag collection bottom cover 208 from the filter cake bottom 207. The user can flexibly lengthen or shorten the folded hose 302 according to the actual use. The oil flowing through the folded hose 302 flows into the oil container through the connecting port 303. This completes the use of the rudder-specific oil drain pipe.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
