Description

A clog-resistant water outlet pipe for hydrogen fuel cell engines Technical Field

[0001] This application relates to the field of automotive engine parts technology, and more specifically, to a clog-resistant water outlet pipe for a hydrogen fuel cell engine. Background Technology

[0002] A hydrogen fuel cell engine is an internal combustion engine that typically uses hydrogen fuel as its energy source. It offers advantages such as low pollution. When operating, a hydrogen fuel cell engine generates a significant amount of heat, requiring cooling. Existing cooling systems usually include a coolant outlet pipe for coolant circulation. However, after prolonged use, impurities can clog the outlet pipe, necessitating regular cleaning. Most existing engine coolant outlet pipes lack anti-clogging mechanisms. Over time, dirt and grime accumulate, clogging the outlet pipe. Failure to regularly clean this pipe reduces the engine's coolant output efficiency and consequently decreases its heat dissipation capacity.

[0003] Therefore, a clog-resistant water outlet pipe for hydrogen fuel cells is needed to solve the above problems. Summary of the Invention

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide an anti-clogging hydrogen fuel cell engine water outlet pipe, comprising: a pipe body with a connecting pipe connected to the engine cover; a water inlet on the pipe body; a water outlet on the pipe body with an anti-clogging seat installed thereon; a connecting end fixed to the anti-clogging seat and coaxially arranged with the water outlet, the inner diameter of the connecting end being the same as the inner diameter of the water outlet; a rotating disk rotatably disposed within the anti-clogging seat; multiple mounting cylinders circumferentially arranged fixed on the rotating disk, one of which is coaxially arranged with the water outlet and connects the water outlet and the connecting end; an open cylinder on the anti-clogging seat, one of which is located at the open cylinder; and a rotating shaft rotatably disposed on the anti-clogging seat, one end of which is fixedly connected to the rotating disk.

[0006] The anti-clogging seat, rotating disc, and mounting cylinder are designed to filter the coolant through the filter screen installed inside the mounting cylinder. Since there are multiple mounting cylinders, when the filter screen in one of the mounting cylinders becomes clogged, rotating the rotating shaft can move the other mounting cylinder to a position coaxial with the water outlet to continue filtering the coolant without having to disassemble and clean the entire water outlet pipe.

[0007] Furthermore, a fixing frame is fixedly connected inside both the connection end and the outlet end, and a sealing plug is fixedly connected to the fixing frame. The diameter of the sealing plug is smaller than the inner diameter of the connection end and the outlet end. Two movable sleeves are slidably connected inside the anti-clogging seat. The outer wall of one movable sleeve slides against the inner wall of the connection end, and the outer wall of the other movable sleeve slides against the inner wall of the outlet end.

[0008] With the sealing plug and movable sleeve, when the filter screen in one of the mounting cylinders becomes clogged and needs to be replaced, the two movable sleeves move, and under the action of the two movable sleeves, the water outlet end and the connection end are connected through the mounting cylinder.

[0009] Furthermore, a first sealing ring is fixedly installed on the movable sleeve. By moving the movable sleeve, the first sealing ring abuts against the sealing plug and seals with the sealing plug. A second sealing ring is fixedly connected to the movable sleeve. By moving the movable sleeve, the second sealing ring abuts against the mounting cylinder coaxial with the water outlet and seals with the mounting cylinder. Both the first and second sealing rings are conical sealing rings.

[0010] With the first and second sealing rings, when the two first sealing rings abut against the two sealing plugs respectively, the water outlet and the connection end are sealed, and the coolant no longer flows, making it convenient to replace the mounting cylinder. At the same time, after the replacement is completed, the two movable sleeves move to make the two second sealing rings abut against the mounting cylinder, thereby connecting the connection end and the water outlet end through the mounting cylinder, and the coolant fully passes through the filter screen in the mounting cylinder.

[0011] Furthermore, the movable sleeve is fixedly connected to a connecting part, and the anti-blocking seat is rotatably connected to a bidirectional screw. The bidirectional screw passes through the two connecting parts and is threadedly connected to the two connecting parts. The threads on the two connecting parts turn in opposite directions. When the bidirectional screw rotates clockwise around its own axis, the two connecting parts move in opposite directions. When the bidirectional screw rotates counterclockwise around its own axis, the two connecting parts move towards each other.

[0012] With the bidirectional screw, when the bidirectional screw rotates clockwise around its own axis, it can drive the two movable sleeves to move, and make the first sealing ring abut against the sealing plug. When the bidirectional screw rotates counterclockwise around its own axis, the two connecting parts move towards each other, and make the second sealing ring abut against the mounting cylinder.

[0013] Furthermore, two anti-overflow sleeves are slidably installed inside the open cylinder. The two anti-overflow sleeves are located on both sides of the two ends of the mounting cylinder. A connecting spring is connected between the anti-overflow sleeve and the open cylinder. The two ends of the connecting spring are fixedly connected to the anti-overflow sleeve and the connecting spring, respectively. A rubber pad is fixed to the end of the anti-overflow sleeve near the mounting cylinder.

[0014] With the addition of an anti-overflow sleeve, when one of the mounting cylinders is in the open cylinder position, the rubber pad on the anti-overflow sleeve abuts against both ends of the mounting cylinder, preventing the coolant in the anti-blocking seat from overflowing from the upper opening of the open cylinder.

[0015] Furthermore, a connecting block is fixedly connected to the anti-overflow sleeve, and multiple circumferentially distributed fixing rods are fixedly connected to the rotating shaft. The number of fixing rods is the same as that of the mounting cylinder. The connecting block has an inclined surface. When the rotating shaft rotates counterclockwise, the fixing rods abut against the inclined surface of the connecting block and push the anti-overflow sleeve to move.

[0016] With the connection block and fixing rod in place, when one of the mounting cylinders moves to the open cylinder position, one of the fixing rods pushes the connection block so that the rubber pad at one end of the anti-overflow sleeve abuts against the mounting cylinder.

[0017] Furthermore, a filter screen is detachably installed inside the rotating disk, which filters the coolant and adsorbs impurities in the coolant.

[0018] Furthermore, an opening is provided at the upper end of the open cylinder, and a sealing cap is installed at the opening.

[0019] An observation window is provided on the sealing cover to observe the position of the installation cylinder.

[0020] The beneficial effects of this application are as follows:

[0021] 1. With the anti-clogging seat, rotating disc, and mounting cylinder, the coolant can be filtered through the filter screen installed inside the mounting cylinder. Since there are multiple mounting cylinders, when the filter screen in one of the mounting cylinders becomes clogged, rotating the rotating shaft can move one of the mounting cylinders to a position coaxial with the water outlet, continuing to filter the coolant without having to disassemble and clean the entire water outlet pipe.

[0022] 2. With the sealing plug and movable sleeve, when the filter screen in one of the mounting cylinders becomes clogged and needs to be replaced, the two movable sleeves move, and under the action of the two movable sleeves, the water outlet end and the connection end are connected through the mounting cylinder.

[0023] 3. With the first and second sealing rings, when the two first sealing rings abut against the two sealing plugs respectively, the outlet end and the connection end are sealed, and the coolant no longer flows, making it convenient to replace the mounting cylinder. At the same time, after the replacement is completed, the two movable sleeves move to make the two second sealing rings abut against the mounting cylinder, thereby connecting the connection end and the outlet end through the mounting cylinder, and the coolant fully passes through the filter screen in the mounting cylinder.

[0024] 4. With the addition of an anti-overflow sleeve, when one of the mounting cylinders is in the open cylinder position, the rubber pad on the anti-overflow sleeve abuts against both ends of the mounting cylinder, preventing the coolant in the anti-blocking seat from overflowing from the upper opening of the open cylinder.

[0039] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0040] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Referring to Figures 1-6, a clog-resistant water outlet pipe for a hydrogen fuel cell engine includes: a pipe body 10, a connecting pipe 11, a water inlet 12, a water outlet 13, an anti-clogging seat 14, a connecting end 15, a rotating disk 23, a mounting cylinder 24, an open cylinder 25, and a rotating shaft 31. The pipe body 10 is provided with multiple connecting pipes 11 that connect to the engine cover, each connected to a cooling chamber of the engine cylinder. The pipe body 10 also has a water inlet 12, which is closed when the water outlet pipe is in use. The pipe body 10 has a water outlet 13 from which coolant flows out. To prevent the accumulation of impurities in the coolant from clogging the outlet pipe, an anti-clogging seat 14 is fixedly installed at the outlet end 13. A connecting end 15, coaxial with the outlet end 13, is fixedly mounted on the anti-clogging seat 14. Coolant flows out through the connecting end 15 after passing through the anti-clogging seat 14. The inner diameter of the connecting end 15 is the same as the inner diameter of the outlet end 13. A rotating disk 23 is rotatably mounted inside the anti-clogging seat 14. Four mounting cylinders 24 are fixed on the rotating disk 23, circumferentially distributed. By rotating the rotating disk 23, one of the mounting cylinders 24 is coaxially aligned with the outlet end 13 and the connecting end 15. A filter screen 33 is installed inside the mounting cylinder 24 to intercept impurities in the coolant. The filter screen 33 can be installed inside the mounting cylinder 24 using screws. The installation method can refer to existing technology: screws pass through the filter screen 33 and are threaded into the mounting cylinder 24, fixing the filter screen 33 inside the mounting cylinder 24 using the screw head.

[0042] A fixing bracket 16 is fixedly connected to both the connecting end 15 and the outlet end 13. A sealing plug 17 is fixedly connected to the fixing bracket 16. The diameter of the sealing plug 17 is smaller than the inner diameter of the connecting end 15 and the outlet end 13, allowing the coolant to flow through the gap between the sealing plug 17 and the connecting end 15, and also through the gap between the sealing plug 17 and the outlet end 13. Two movable sleeves 18 are slidably connected inside the anti-clogging seat 14. The outer wall of one movable sleeve 18 slides against the inner wall of the connecting end 15, and the outer wall of the other movable sleeve 18 slides against the inner wall of the outlet end 13, so that the two movable sleeves 18 respectively seal against the outlet end 13 and the connecting end 15. A first sealing ring 19 is fixedly connected to the movable sleeve 18. The inner side of the first sealing ring 19 is conical. When the movable sleeve 18 moves to the point where the first sealing ring 19 abuts against the sealing plug 17, the first sealing ring 19 and the sealing plug 17 seal each other. At this time, the movable sleeve 18 and the first sealing ring 19 cooperate to seal the water outlet 13 and the connecting end 15. A second sealing ring 20 is also fixedly connected to the movable sleeve 18. The outer side of the second sealing ring 20 is conical. When the movable sleeve 18 moves to the point where the second sealing ring 20 abuts against the mounting cylinder 24, the connecting end 15 and the water outlet 13 are connected through the mounting cylinder 24, allowing the coolant to fully pass through the mounting cylinder 24.

[0043] The movable sleeve 18 is fixedly connected to a connecting part 21, and the anti-blocking seat 14 is rotatably connected to a bidirectional screw 22. The bidirectional screw 22 passes through the two connecting parts 21 and is threadedly connected to the two connecting parts 21. The threads on the two connecting parts 21 turn in opposite directions. When the bidirectional screw 22 rotates clockwise around its own axis, the two connecting parts 21 move in opposite directions. When the bidirectional screw 22 rotates counterclockwise around its own axis, the two connecting parts 21 move towards each other.

[0044] A rotating shaft 31 is rotatably connected to the anti-blocking seat 14. One end of the rotating shaft 31 is fixed to the rotating disk 23. When the rotating shaft 31 is rotated, the rotating disk 23 is driven to rotate, thereby adjusting the position of the mounting cylinder 24.

[0045] An open sleeve 25 is also provided on the anti-clogging seat 14. When one of the mounting sleeves 24 is coaxial with the water outlet 13, one mounting sleeve 24 is located at the position of the open sleeve 25 and is coaxial with the open sleeve 25. Two anti-overflow sleeves 27 are slidably arranged inside the open sleeve 25. The two anti-overflow sleeves 27 are located on both sides of the two ends of the mounting sleeve 24. A connecting spring 29 connects the anti-overflow sleeve 27 and the open sleeve 25. The two ends of the connecting spring 29 are fixedly connected to the anti-overflow sleeve 27 and the connecting spring 29, respectively. A rubber pad 28 is fixed to the end of the anti-overflow sleeve 27 near the mounting sleeve 24. When one of the mounting sleeves 24 is located at the position of the open sleeve 25, the rubber pad 28 on the anti-overflow sleeve 27 abuts against the two ends of the mounting sleeve 24 to prevent the coolant in the anti-clogging seat 14 from overflowing from the upper opening of the open sleeve 25.

[0046] A connecting block 30 is fixedly connected to the anti-overflow sleeve 27, and four circumferentially distributed fixing rods 32 are fixedly connected to the rotating shaft 31. The connecting block 30 has an inclined surface. When the rotating shaft 31 rotates counterclockwise, the fixing rods 32 abut against the inclined surface of the connecting block 30 and push the anti-overflow sleeve 27 to move. When one of the mounting cylinders 24 moves to the position of the open cylinder 25, one of the fixing rods 32 pushes the connecting block 30 so that the rubber pad 28 at one end of the anti-overflow sleeve 27 abuts against the mounting cylinder 24. The upper end of the open cylinder 25 is provided with an opening, and a sealing cover 26 is installed at the opening. The sealing cover 26 has an observation window that allows observation of the position of the mounting cylinder 24.

[0047] Working process or usage method:

[0048] 1. When the filter screen 33 in one of the mounting cylinders 24 becomes clogged, the two movable sleeves 18 are moved by rotating the double-acting screw 22 clockwise, so that the first sealing ring 19 contacts the sealing plug 17, sealing the water outlet 13 and the connecting end 15. At this time, the coolant stops flowing. Then, the rotating shaft 31 is rotated, so that the rotating disk 23 rotates, and the other mounting cylinder 24 is rotated to the coaxial position of the water outlet 13. By observing the position of the mounting cylinder 24 at the opening cylinder 25, it can be determined whether one of the mounting cylinders 24 is coaxial with the water outlet 13. After the adjustment is completed, the double-acting screw 22 is rotated counterclockwise, so that the two second sealing rings 20 abut against the two ends of the mounting cylinder 24, so that the coolant can flow through the mounting cylinder 24 fully.

[0049] 2. When it is necessary to replace and clean the filter screen 33 inside the mounting cylinder 24, one of the mounting cylinders 24 is located in the position of the open cylinder 25. At this time, the connecting block 30, under the action of the fixing rod 32, causes the two rubber pads 28 to abut against the two ends of the mounting cylinder 24, and the connecting spring 29 is in a stretched state. At this time, the sealing cover 26 can be opened, and the filter screen 33 can be taken out for replacement and cleaning.

[0050] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
