Description

Technical Field

[0001] The invention belongs to the technical field of ventilation and air exchange of diesel generator sets, and specifically refers to an air scoop of a diesel generator set suitable for use in a low-temperature environment. Background Art

[0002] The wind scoop is a ventilation device. When the wind scoop is used in a diesel generator set, its main function is to maintain ventilation of the diesel generator set, allow sufficient oxygen to participate in the operation of the diesel generator set, and discharge the exhaust gas generated when the diesel generator set is working.

[0003] However, when diesel generator sets are used in polar regions, due to the extremely harsh environment in the polar regions, traditional wind buckets may freeze and become unable to be adjusted. Since the opening and closing degree of the wind bucket cannot be adjusted, the diesel generator sets will be in a low-temperature working environment for a long time. The low-temperature working environment will make the air temperature entering the diesel generator set extremely low, making it impossible for the diesel inside the diesel generator set to continue to burn, thus causing power outages. Summary of the invention

[0011] Furthermore, the wind scoop box includes a wind scoop side plate, a wind scoop back plate, a wind scoop bottom plate, and a mounting hole. The wind scoop back plate is fixedly connected to the rear of the wind scoop bottom plate. Wind scoop side plates are estimated to be provided on both sides of the wind scoop bottom plate. The two edges of the wind scoop side plate that are not connected to the wind scoop back plate and the wind scoop bottom plate both have a certain curvature. The wind scoop side plate is provided with a mounting hole, and the mounting hole passes through the wind scoop side plate.

[0012] Furthermore, a wind bucket connecting shaft is rotatably connected between the two groups of wind bucket connecting rods, a connecting rod positioning shaft is provided at the lower part of any group of wind bucket connecting rods, and the front part of the second wind bucket opening and closing rod is rotatably connected to the connecting rod positioning shaft.

[0013] Furthermore, the first wind scoop opening and closing rod includes a middle column connecting hole, a first pin shaft hole, a fixing hole, a closing hole, a main body connecting piece, an oblique piece and a manual piece.

The tail of the main body connecting piece is provided with a middle column connecting hole, and the middle column connecting hole passes through the main body connecting piece. The front of the middle column connecting hole is provided with a first pin shaft hole, and the first pin shaft hole passes through the main body connecting piece. The front of the first pin shaft hole is provided with a fixing hole, and the fixing hole passes through the main body connecting piece. The front of the fixing hole is provided with a closing hole, and the closing hole passes through the main body connecting piece.

[0014] Furthermore, a first angle between the main body connecting piece and the oblique piece is 150°, and a second angle between the manual piece and the oblique piece is 150°.

[0015] Furthermore, the second wind bucket opening and closing rod includes a connecting hole, a limiting hole and a second pin shaft hole, the connecting hole is arranged at the front part of the second wind bucket opening and closing rod, the connecting hole passes through the second wind bucket opening and closing rod, the limiting hole is arranged at the rear part of the connecting hole, the limiting hole passes through the second wind bucket opening and closing rod, the second pin shaft hole is arranged at the rear part of the limiting hole, and the second pin shaft hole passes through the second wind bucket opening and closing rod.

[0021] (1) By combining multiple sets of wind scoops with two sets of wind scoop connecting rods, multiple sets of wind scoops can be opened or closed at the same time. When multiple sets of wind scoops are opened, the air around the diesel generator set can be kept flowing, so that a steady stream of oxygen can flow through the diesel generator set. In the process of air circulation, the exhaust gas generated by diesel combustion can also be taken away, so that the diesel generator set is always in a good working environment;

[0022] (2) Since the temperature in the polar regions is low and the wind speed is high, in order to ensure that the diesel generator set operates in a good environment, it is necessary to adjust the opening and closing degree of the wind bucket according to different weather conditions. By manually controlling the first wind bucket opening and closing lever, manual operation can be achieved. Even if extremely severe weather conditions cause ice to form in some places, since this embodiment adopts a simple mechanical structure, the wind bucket can be quickly closed by manual deicing.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In the description of the present invention, the term "low temperature" refers to a temperature range of -20 to -40°C.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a wind bucket for a diesel generator set suitable for use in a low temperature environment, comprising a plurality of wind buckets 1, two wind bucket connecting rods 2, a first wind bucket opening and closing pull rod 3, a second wind bucket opening and closing pull rod 5, a wind bucket closing fixing seat 10 and a center column positioning shaft 11;

[0042] The plurality of wind buckets 1 are configured to ventilate the diesel generator set, and the plurality of wind buckets 1 are rotatably connected to the wind bucket connecting rod 2;

[0043] The first wind bucket opening and closing pull rod 3 is configured to adjust the opening and closing degree of the wind bucket 1, and the tail of the first wind bucket opening and closing pull rod 3 is rotatably connected to the center column positioning shaft 11;

[0044] The second wind bucket opening and closing pull rod 5 is configured to assist in adjusting the opening and closing degree of the wind bucket 1, and the front portion of the second wind bucket opening and closing pull rod 5 is rotationally connected to the wind bucket connecting rod 2;

[0045] The wind scoop closing fixing seat 10 is configured as a device that can keep multiple groups of wind scoops 1 in a closed state, and the wind scoop closing fixing seat 10 is located at the rear of the wind scoop 1.

[0046] In this embodiment, the diesel generator set refers to a mechanical equipment that uses diesel as fuel to convert other forms of energy into electrical energy. During the energy conversion process, the diesel needs to be burned continuously, so it is necessary to ensure that the diesel generator set is always in a well-ventilated state. By combining multiple sets of wind buckets 1 with two sets of wind bucket connecting rods 2, multiple sets of wind buckets 1 can be in an open or closed state at the same time. When the multiple sets of wind buckets 1 are open, the air around the diesel generator set can be kept in a flowing state, so that a steady supply of oxygen can flow through the diesel generator set. In the process of air circulation, the exhaust gas generated by diesel combustion can also be taken away, so that the diesel generator set is always in a good working environment.

[0047] However, if the diesel generator set is used in the polar regions, due to the extremely harsh environment in the polar regions, if the diesel generator set is operated in a low temperature environment for a long time, the temperature of the compressed air in the combustion chamber of the diesel generator set will decrease, thereby causing the diesel generator set to be unable to operate normally. By rotatably connecting the front section of the wind bucket 1 to the wind bucket connecting rod 2, and rotatably connecting the rear end of the first wind bucket opening and closing rod 3 to the center column positioning shaft 11, and finally connecting the front section of the second wind bucket opening and closing rod 5 to the wind bucket connecting rod 2, the rear end of the second wind bucket opening and closing rod 5 is rotatably connected to the first wind bucket opening and closing rod 3.

[0048] Thus, the first wind bucket opening and closing pull rod 3 can be manually held to rotate up and down with the center column positioning axis 11 as the center. When the first wind bucket opening and closing pull rod 3 rotates downward, the second wind bucket opening and closing pull rod 5 will follow the downward rotation and move forward. When the second wind bucket opening and closing pull rod 5 moves forward, the wind bucket connecting rod 2 will move forward. At this time, if the other end of the wind bucket 1 is fixed at a certain place, when the wind bucket connecting rod 2 moves forward, it will drive the wind bucket 1 to rotate around a fixed point.

[0049] The above process is the process of opening the wind bucket 1. When the first wind bucket opening and closing rod 3 moves in the opposite direction, the wind bucket 1 is in the closing process. Due to the low temperature and high wind speed in the polar regions, in order to ensure that the diesel generator set operates in a good environment, it is necessary to adjust the opening and closing degree of the wind bucket 1 according to different weather conditions. By manually controlling the first wind bucket opening and closing rod 3, manual operation can be achieved. Even in extremely severe weather conditions that cause ice to form in some places, since this embodiment adopts a simple mechanical structure, the wind bucket 1 can be quickly closed by manual deicing.

[0050] like Figure 4 As shown, the wind bucket 1 includes a wind bucket connecting ring 101, a wind bucket connecting shaft 102, a wind bucket box 103 and a wind bucket limiting spring 104, two groups of wind bucket connecting rings 101 are fixedly connected to the rear of the wind bucket box 103, the wind bucket connecting shaft 102 is located between the two groups of wind bucket connecting rings 101, the wind bucket connecting shaft 102 is rotationally connected to the two groups of wind bucket connecting rings 101, and wind bucket limiting springs 104 are fixedly connected to both sides of the wind bucket box 103.

[0051] In this embodiment, first, two sets of wind bucket connecting rings 101 are connected to the back of the wind bucket box 103, and then the wind bucket connecting shaft 102 is passed through the two sets of wind bucket connecting rings 101, and the wind bucket connecting rings 101 are rotatably connected to the wind bucket connecting shaft 102, so that the wind bucket connecting shaft 102 can rotate between the two sets of wind bucket connecting rings 101, and after the wind bucket connecting shaft 102 passes through the two sets of wind bucket connecting rings 101, it is rotatably connected to the two sets of wind bucket connecting rods 2, and then when the two sets of wind bucket connecting rods 2 move, they can drive the wind bucket connecting shaft 102 to rotate, and when the wind bucket connecting shaft 102 moves, it will drive the wind bucket box 103 to move.

[0052] Due to the extremely bad weather at the two poles, the wind box 103 is very likely to shake in a windy environment, thereby reducing its service life. To prevent the above problem, a wind bucket limit spring 104 needs to be installed at the rear of the wind box 103 to reduce the shaking in a windy environment through the elastic damping of the wind bucket limit spring 104.

[0053] like Figure 5 As shown, the wind bucket box 103 includes a wind bucket side plate 1031, a wind bucket back plate 1032, a wind bucket bottom plate 1033, and a mounting hole 1034. The rear of the wind bucket bottom plate 1033 is fixedly connected to the wind bucket back plate 1032. Both sides of the wind bucket bottom plate 1033 are estimated to have wind bucket side plates 1031. The two edges of the wind bucket side plate 1031 that are not connected to the wind bucket back plate 1032 and the wind bucket bottom plate 1033 have a certain curvature. The wind bucket side plate 1031 is provided with a mounting hole 1034, and the mounting hole 1034 passes through the wind bucket side plate 1031.

[0054] In this embodiment, a wind scoop back plate 1032 is installed at the rear of the wind scoop bottom plate 1033, and wind scoop side plates 1031 are installed on both sides of the wind scoop bottom plate 1033, so that the wind scoop 1 as a whole is an open box shape; and because the wind scoop 1 as a whole is an open box shape, when the external high-speed airflow enters the wind scoop 1, it will first hit the wind scoop back plate 1032, and change the airflow direction through the wind scoop back plate 1032, and then enter the diesel generator set. During this turning process, the high-speed external airflow will reduce the gas flow rate during the collision process, thereby placing the diesel generator set in a relatively mild external environment.

[0055] By making the two edges of the wind bucket side plate 1031 that are not connected to the wind bucket back plate 1032 and the wind bucket bottom plate 1033 have a certain curvature, the friction generated during the opening and closing process of the wind bucket box 103 can also be reduced.

[0056] like Figure 1 , Figure 2 and Figure 3As shown, a wind bucket connecting shaft 102 is rotatably connected between the two groups of wind bucket connecting rods 2, a connecting rod positioning shaft 12 is provided at the lower part of any group of wind bucket connecting rods 2, and the front part of the second wind bucket opening and closing rod 5 is rotatably connected to the connecting rod positioning shaft 12.

[0057] In this embodiment, the front portion of the second wind bucket opening and closing rod 5 is rotationally connected to the connecting rod positioning shaft 12, so that when the second wind bucket opening and closing rod 5 moves, the wind bucket connecting rod 2 can be driven to move, and the movement of the wind bucket connecting rod 2 can drive subsequent parts to move.

[0058] like Figure 6 and Fig. 9 As shown, the first wind bucket opening and closing pull rod 3 includes a middle column connecting hole 301, a first pin shaft hole 302, a fixing hole 303, a closing hole 304, a main body connecting piece 305, an oblique piece 306 and a manual piece 307. The main body connecting piece 305 is fixedly connected to the rear of the oblique piece 306, and the manual piece 307 is fixedly connected to the front of the oblique piece 306. The tail of the main body connecting piece 305 is provided with a middle column connecting hole 301, and the middle column connecting hole 301 passes through the main body connecting piece 305. The front part of the middle column connecting hole 301 is provided with a first pin shaft hole 302, and the first pin shaft hole 302 passes through the main body connecting piece 305. The front part of the first pin shaft hole 302 is provided with a fixing hole 303, and the fixing hole 303 passes through the main body connecting piece 305. The front part of the fixing hole 303 is provided with a closing hole 304, and the closing hole 304 passes through the main body connecting piece 305.

[0059] In this embodiment, by providing a center column connecting hole 301 and passing the center column positioning shaft 11 through the center column connecting hole 301, the first wind bucket opening and closing rod 3 can rotate with the center column positioning shaft 11 as the center of a circle, and the remaining holes are used to insert corresponding components, so that when the first wind bucket opening and closing rod 3 moves, the remaining components follow the movement, or the first wind bucket opening and closing rod 3 is fixed.

[0060] like Figure 7 and Fig. 9 As shown, the first angle N between the main body connecting piece 305 and the oblique piece 306 is 150°, and the second angle L between the manual piece 307 and the oblique piece 306 is 150°.

[0061] In this embodiment, in order to prevent the operator from being caught by the moving parts when manually operating the first wind bucket opening and closing rod 3, the second angle L between the manual plate 307 and the oblique plate 306 is set to 150°, thereby ensuring the safety of the operator during use. The first angle N between the main connecting plate 305 and the oblique plate 306 is set to 150°, which can also provide a certain amount of movement space when holding subsequent parts to prevent the parts from getting stuck during movement.

[0062] like Figure 8 and Fig. 9 As shown, the second wind bucket opening and closing rod 5 includes a connecting hole 501, a limiting hole 502 and a second pin shaft hole 503. The connecting hole 501 is arranged at the front of the second wind bucket opening and closing rod 5, and the connecting hole 501 passes through the second wind bucket opening and closing rod 5. The limiting hole 502 is arranged at the rear of the connecting hole 501, and the limiting hole 502 passes through the second wind bucket opening and closing rod 5. The second pin shaft hole 503 is arranged at the rear of the limiting hole 502, and the second pin shaft hole 503 passes through the second wind bucket opening and closing rod 5.

[0063] In this embodiment, after the connecting rod positioning shaft 12 passes through the connecting hole 501, the second wind bucket opening and closing rod 5 can rotate the connecting rod positioning shaft 12 as a circle, and the second wind bucket opening and closing rod 5 and the wind bucket connecting rod 2 are connected into a whole through the connecting rod positioning shaft 12, ensuring that when the second wind bucket opening and closing rod 5 moves under the action of external force, the wind bucket connecting rod 2 will also follow the movement.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a limit lock 4, an air inlet beam 6, a column connecting rod 7, two sets of box center columns 8, and a positioning pin 9;

[0065] The two groups of the box center columns 8 are configured as devices connected to the external box of the diesel generator set. The lower part of any group of the box center columns 8 is fixedly connected with a wind bucket closing fixing seat 10, and the lower part of any group of the box center columns 8 is fixedly connected with a center column positioning shaft 11. The wind bucket closing fixing seat 10, the center column positioning shaft 11 and the connecting rod positioning shaft 12 are located on the same side, and the center column positioning shaft 11 is located at the lower part of the wind bucket closing fixing seat 10;

[0066] A set of air inlet beams 6 are fixedly connected to the upper and lower parts of the two sets of center columns 8 of the box body, the column connecting rod 7 passes through the mounting hole 1034 and is connected to the two sets of center columns 8 of the box body, and the positioning pin 9 passes through the second pin shaft hole 503 and the first pin shaft hole 302 and is connected with the cotter pin.

[0067] In this embodiment, by inserting the limit lock 4 into the limit hole 502, the limit lock 4 becomes an obstacle to the movement of the first wind bucket opening and closing rod 3. When the first wind bucket opening and closing rod 3 is manually operated to move to a certain position, the limit lock 4 is tightened at this time, so that the bottom of the first wind bucket opening and closing rod 3 can be against the limit lock 4, so that the first wind bucket opening and closing rod 3 will not continue to move due to its own weight, thereby locking the first wind bucket opening and closing rod 3, and then the subsequent components can be locked to prevent the wind bucket 1 from continuing to move, thereby ensuring that the wind bucket 1 can maintain a fixed opening and closing degree. When the limit hole 502 is aligned with the fixing hole 303, the limit lock 4 is inserted to further fix the wind bucket 1, so that the wind bucket 1 will not be displaced under the blowing of external airflow, thereby ensuring the opening and closing degree of the wind bucket 1.

[0068] By connecting the two center columns 8 of the box body with the outer box of the diesel generator set and adding an air inlet beam 6 between the two center columns 8 of the box body, the center column 8 of the box body and the air inlet beam 6 form an integral frame, and then the column connecting rod 7 is passed through the mounting hole 1034 and rotatably connected with the center column 8 of the box body, so that the wind scoop 1, the center column 8 of the box body and the air inlet beam 6 form a whole.

[0069] The positioning pin 9 passes through the second pin shaft hole 503 and the first pin shaft hole 302 and is connected with the split pin, thereby ensuring that when the first wind bucket opening and closing pull rod 3 is operated, the second wind bucket opening and closing pull rod 5 will also move accordingly.

[0070] Furthermore, a fixing lock 13 is provided at the front of the wind scoop closing fixing seat 10 .

[0071] In this embodiment, the fixing lock 13 is first unscrewed, and then the first wind bucket opening and closing rod 3 is manually operated to align the closing hole 304 with the wind bucket closing fixing seat 10, and then the fixing lock 13 is inserted into the closing hole 304 and tightened, so that the wind bucket 1 can be completely closed.
