Technical Field
[0001] This utility model relates to the field of diesel engine wind and sand protection technology, specifically to a diesel generator set air intake wind and sand protection component. Background Technology
[0002] In many environments where diesel generator sets are used, especially in deserts, Gobi, coastal areas with strong winds and sandstorms, and some industrial sites with severe wind and sand pollution, wind and sand problems pose a serious threat to the normal operation of diesel generator sets.
[0003] For example, application number CN220487718U discloses a diesel generator set air intake and sand-proof component, including a diesel engine silent outer casing. The silent outer casing is provided with a top cover, a front sealing plate, and side plates. An A mounting seat is provided at the bottom of the surface of the front sealing plate. Two sets of side plates are symmetrically arranged on both sides of the bottom of the top cover, and a B mounting seat is provided on the side of each side plate facing the front sealing plate. Matching sand-proof components are provided on the outer sides of both the A and B mounting seats. Through the cooperative arrangement of the A and B mounting seats, a pre-reserved installation position is provided on the existing silent outer casing. This installation position is located outside the original air intake of the casing, thereby installing the sand-proof component, which blocks the movement of sand and reduces the amount of sand entering the generator set casing, increasing the service life of the generator set and reducing maintenance costs.
[0004] The aforementioned and existing technologies use a mesh screen in the wind and sand filter to prevent sand from entering the generator. However, the lack of a cleaning mechanism necessitates manual cleaning after a period of use, which affects the air intake of the diesel generator and increases labor intensity. Therefore, there is an urgent need to design a wind and sand filter for diesel generator sets to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a windproof and sandproof component for the air intake of a diesel generator set to address the aforementioned shortcomings in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A diesel generator set air intake and sand-proof component includes a chassis. An air intake is provided on one side of the chassis. An L-shaped air intake cover is fixedly connected to the outer wall of the chassis near the air intake. A motor is fixedly connected to the outer wall of the L-shaped air intake cover near the bottom. A rotating rod is fixedly connected to the output end of the motor through the L-shaped air intake cover. A U-shaped rod is fixedly connected to the other end of the rotating rod. A strip hole is provided in the middle of the U-shaped rod. The same double-acting screw is rotatably connected between the two ends of the inner side of the U-shaped rod, and the double-acting screw is coaxial with the rotating rod. Both ends of the double-acting screw are screwed with screw blocks. A screw nut adapted to the double-acting screw is fixedly sleeved on each of the two screw blocks. A connecting rod is rotatably connected to the side of each of the two screw blocks near the strip hole. The two connecting rods are rotatably connected to the same connector through the strip hole.
[0008] As a further embodiment of this utility model, a cylinder is fixedly connected to one end of the U-shaped rod away from the rotating rod, and the cylinder is coaxial with the rotating rod. The other end of the cylinder passes through the L-shaped air intake cover and has multiple slots. The outer wall of the L-shaped air intake cover has a circular hole that matches the cylinder.
[0009] As a further embodiment of this utility model, a round rod is fixedly connected to the end of the bidirectional lead screw away from the motor, and the round rod passes through the U-shaped rod and is rotatably sleeved on the inner wall of the cylinder. The round rod, the cylinder, and the bidirectional lead screw are all coaxial with the rotating rod to ensure that the motor rotates and the equipment is in a stable state. A round hole adapted to the round rod is opened on the U-shaped rod, and a square rod is fixedly connected to the other end of the round rod. A protrusion is fixedly connected to the other end of the square rod.
[0010] As a further embodiment of this utility model, a knob is slidably fitted on the circumferential surface of the square rod, and a circular hole adapted to the square rod is opened in the middle of the knob. Multiple locking blocks are fixedly connected to the side of the knob near the locking slot, and the locking blocks are adapted to the locking slot. A second spring is fitted on the end of the square rod near the protrusion.
[0011] As a further embodiment of this utility model, a square perforated plate is fixedly connected to the inner wall of the L-shaped air intake near the bottom. Sliding rods are slidably fitted at both ends of the square perforated plate. Four round holes adapted to the sliding rods are opened on the square perforated plate. The setting of the four sliding rods allows the U-shaped frame and filter screen to vibrate stably up and down. The bottom of the four sliding rods is fixedly connected to the same U-shaped frame. A first spring is fitted on the top of the four sliding rods at the square perforated plate.
[0012] As a further embodiment of this utility model, the top of the four slide rods is fixedly connected to the same I-beam plate, and the I-beam plate is adapted to the connector. Through the continuous impact of the connector on the I-beam plate, the U-shaped frame, filter screen, etc. are continuously vibrated up and down, so that dust and other impurities will not adhere to the bottom of the filter screen.
[0013] As a further embodiment of this utility model, the inner wall of the U-shaped frame is provided with sliding grooves on both sides, and the same square frame is slidably fitted between the two sliding grooves. A filter screen is fixedly connected to the middle of the square frame, and push blocks are fixedly connected to the outer sides of both ends of the U-shaped frame. The bottom of the L-shaped air intake cover is provided with slots that are adapted to the push blocks on both sides. By pressing the push blocks, the U-shaped frame, square frame, etc. can be manually lowered, which is convenient for replacing the filter screen.
[0014] As a further embodiment of this utility model, an inspection door is provided on the outside of the chassis, which facilitates the maintenance of the generator inside the chassis.
[0015] The beneficial effects of this utility model are as follows:
[0016] This utility model employs technologies such as a motor, rotating rod, U-shaped rod, double-acting screw, connecting rod, knob, U-shaped frame, sliding rod, and I-beam plate. Through the rotation of the motor, the connecting parts continuously press against the I-beam plate, causing the frame and filter screen to vibrate continuously. Simultaneously, by pulling and rotating the knob, the eccentricity between the connecting parts and the rotating rod is adjusted, thereby regulating the vibration amplitude of the filter screen. This effectively solves the problem of the lack of a cleaning mechanism for the filter screen mentioned in the background technology. It achieves air filtration while simultaneously ensuring continuous vibration of the filter screen, making it difficult for impurities at the bottom of the filter screen to adhere. The vibration amplitude of the filter screen can be adjusted in real time according to the usage scenario, improving the practicality of the equipment and resulting in more stable operation of the diesel generator.
[0017] This invention features a first spring, a sliding groove, a square frame, and a toggle block. When the filter needs to be replaced, pressing the toggle block lowers the U-shaped frame to the bottom, allowing it to be pulled out from the bottom of the L-shaped air intake cover, thus enabling quick and easy filter replacement.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] like Figures 1-6As shown in the figure, the present invention provides a diesel generator set air intake and sand-proof component, including a chassis 1. An air inlet is provided on one side of the chassis 1. An L-shaped air intake shroud 3 is fixedly connected to the outer wall of the chassis 1 near the air inlet. A motor 7 is fixedly connected to the outer wall of the L-shaped air intake shroud 3 near the bottom. A rotating rod 701 is fixedly connected to the output end of the motor 7 through the L-shaped air intake shroud 3. A U-shaped rod 9 is fixedly connected to the other end of the rotating rod 701. A strip-shaped hole 901 is provided in the middle of the U-shaped rod 9. The same bidirectional lead screw 10 is rotatably connected between the two ends of the inner side of the U-shaped rod 9, and the bidirectional lead screw 10 is coaxial with the rotating rod 701. Both ends of the bidirectional lead screw 10 are screwed together. There are two screw blocks 11, and each screw block 11 is fixedly fitted with a screw nut that matches the bidirectional screw 10. By rotating the bidirectional screw 10, the two screw blocks 11 move closer or further apart, thereby adjusting the eccentricity of the connecting piece 13 and the rotating rod 701. Each of the two screw blocks 11 is rotatably connected to a connecting rod 12 on the side near the slotted hole 901. Both connecting rods 12 pass through the slotted hole 901 and are rotatably connected to the same connecting piece 13. The slotted hole 901 is designed so that when the equipment is working, the two connecting rods 12 can synchronously drive the I-plate 402 at the bottom of the connecting piece 13 to continuously impact along with the rotating rod 701.
[0029] Specifically, in this embodiment, a cylinder 8 is fixedly connected to one end of the U-shaped rod 9 away from the rotating rod 701, and the cylinder 8 is coaxial with the rotating rod 701. The other end of the cylinder 8 passes through the L-shaped air intake shroud 3 and has multiple slots 801. The slots 801 are designed so that under normal conditions, the round rod 14, the square rod 15 and the bidirectional lead screw 10 can rotate synchronously with the cylinder 8. The outer wall of the L-shaped air intake shroud 3 has a round hole that matches the cylinder 8.
[0030] Specifically, in this embodiment, a round rod 14 is fixedly connected to one end of the bidirectional lead screw 10 away from the motor 7, and the round rod 14 passes through the U-shaped rod 9 and is rotatably sleeved on the inner wall of the cylinder 8. A round hole adapted to the round rod 14 is opened on the U-shaped rod 9, and a square rod 15 is fixedly connected to the other end of the round rod 14. A protrusion 17 is fixedly connected to the other end of the square rod 15.
[0031] Specifically, in this embodiment, a knob 18 is slidably sleeved on the circumferential surface of the square rod 15. A circular hole adapted to the square rod 15 is opened in the middle of the knob 18. A plurality of locking blocks 19 are fixedly connected to the side of the knob 18 near the locking groove 801, and the locking blocks 19 are adapted to the locking groove 801. The cooperation between the locking blocks 19 and the locking groove 801 makes the bidirectional lead screw 10 rotate synchronously when the cylinder 8 rotates with the U-shaped rod 9. A second spring 16 is sleeved on the end of the square rod 15 near the protrusion 17. The setting of the second spring 16 makes it so that under normal circumstances, the locking blocks 19 of the knob 18 will not separate from the locking groove 801.
[0032] Specifically, in this embodiment, a square perforated plate 4 is fixedly connected to the inner wall of the L-shaped air intake hood 3 near the bottom. Sliding rods 401 are slidably fitted at both ends of the square perforated plate 4. Four round holes adapted to the sliding rods 401 are opened on the square perforated plate 4. The bottom of the four sliding rods 401 is fixedly connected to the same U-shaped frame 5. A first spring 403 is fitted at the top of the four sliding rods 401. The setting of the first spring 403 facilitates the rebound of the square frame 6 and the U-shaped frame 5, and also facilitates the lowering of the U-shaped frame 5 when the filter screen 601 is replaced.
[0033] Specifically, in this embodiment, the top of the four slide bars 401 is fixedly connected to the same I-beam plate 402, and the I-beam plate 402 is adapted to the connector 13. Through the continuous impact of the connector 13 on the I-beam plate 402, the filter screen 601 and the U-shaped frame 5 vibrate continuously.
[0034] Specifically, in this embodiment, the inner walls of the U-shaped frame 5 are provided with sliding grooves 501 on both sides, and the same square frame 6 is slidably fitted between the two sliding grooves 501. A filter screen 601 is fixedly connected to the middle of the square frame 6. A push block is fixedly connected to the outer sides of both ends of the U-shaped frame 5. The bottom sides of the L-shaped air intake hood 3 are provided with slots that are adapted to the push blocks. When the filter screen 601 needs to be replaced, the first spring 403 is compressed by pressing the two push blocks, which causes the U-shaped frame 5 to descend to the bottom. At this time, the square frame 6 can slide out from the sliding groove 501 to realize the replacement.
[0035] Specifically, in this embodiment, an inspection door 2 is provided on the outside of the chassis 1. The inspection door 2 facilitates the maintenance of the generator inside.
[0036] Working principle: During operation, the diesel generator inside the casing 1 draws in air through the air inlet of the L-shaped air intake shroud 3. Outside air enters the casing 1 through the sliding groove 501 at the bottom of the L-shaped air intake shroud 3, thus supplying air. The filter screen 601 prevents sand and dust from entering the casing 1. Simultaneously, when the diesel generator is operating, the motor 7 is turned on, causing the rotating rod 701, along with the U-shaped rod 9, to rotate. Through the rotation of the connecting piece 13, the middle of the I-beam plate 402 is continuously pushed and compressed, causing the I-beam plate 402, along with the U-shaped frame 5 and the square frame 6, to move downwards. Under the action of the first spring 403, it returns to its original position, and this cycle repeats. The operation causes the U-shaped frame 5 and filter screen 601 to vibrate continuously up and down, preventing dust and impurities from adhering to the filter screen 601, thus reducing the frequency of manual replacement of the filter screen 601. At the same time, by pulling the knob 18, the second spring 16 is compressed, causing the locking block 19 to separate from the locking groove 801. Then, by rotating the knob 18, the round rod 14 and the two-way lead screw 10 rotate, causing the two two-way lead screws 10 to move closer or further apart, thereby adjusting the eccentric height of the connecting piece 13 and the rotating rod 701, and thus adjusting the vibration amplitude of the U-shaped frame 5 and the square frame 6, etc., so that the vibration amplitude of the filter screen 601 can be adjusted in real time according to different environments, thereby improving the self-cleaning strength of the filter screen 601.
[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
