Description

Technical Field

[0001] This utility model relates to the technical field of dust prevention equipment for generator sets. More specifically, this utility model relates to a dust prevention device for generator sets. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. The electrical energy converted by the generator is output to electrical equipment for use. During operation, especially in outdoor or industrial environments, generator sets often face the problem of dust, sand, and other impurities entering the system. These impurities not only affect the generator set's heat dissipation efficiency but may also lead to accelerated wear of internal mechanical parts and reduced insulation performance of electrical components, thereby shortening the generator set's lifespan and increasing maintenance costs. To reduce the impact of dust, a dust cover is needed for the generator set, and a filter screen is installed in the dust cover to prevent dust. However, the filter screen is prone to clogging, affecting heat dissipation. Patent publication number "CN 219262513U" discloses a dustproof structure for a generator set, which uses a removable mesh screen. However, this dustproof device cannot clean the mesh screen in a timely manner during use, and the clogging of the mesh screen affects the heat dissipation effect. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] Another objective of this invention is to provide a dustproof device for generator sets, which uses a vertically movable scraper to promptly remove dust or impurities from the first filter screen, thereby preventing blockage of the screen's mesh and improving the heat dissipation effect on the generator set.

[0005] To achieve these objectives and other advantages of this utility model, a dust prevention device for generator sets is provided, comprising:

[0006] A dust cover is installed on the generator set. One end of the dust cover has an air inlet and the other end has an air outlet. A suction fan is installed at the air outlet.

[0007] The filtration mechanism includes a mounting block detachably connected to the air inlet. The mounting block has a filter port at its lower part. Multiple first filter screens are sequentially mounted at the filter port along its depth direction. The mesh size of the first filter screens decreases sequentially along the depth direction of the filter port. The portion of the mounting block located below the filter port is connected to a dust collection chamber to collect impurities on the first filter screens. The first filter screens are provided with scraper blades that can move up and down relative to them.

[0008] Preferably, the mounting block above the filter port has a drive cavity, and the drive cavity has a drive plate that can slide up and down relative to it. The drive plate has multiple pairs of drive rods, which are arranged one-to-one with multiple scraper plates. The drive rods slide through the bottom of the drive cavity in a sealed manner and are connected to the scraper plates.

[0009] Preferably, the mounting block has an elongated opening that communicates with the drive cavity. The mounting block is equipped with a first telescopic motor, and the output shaft of the first telescopic motor has an L-shaped push-pull rod at its end. One side of the push-pull rod slides up and down through the opening, and the other end is connected to the drive plate to drive the drive plate to move up and down.

[0010] Preferably, the mesh of the first filter screen is divided into multiple groups along the horizontal direction;

[0011] It also includes a hole cleaning assembly, which includes a fixed plate disposed inside the dust cover and movable relative to the dust cover. The fixed plate is arranged along the length direction of the first filter screen. The fixed plate is provided with a long strip-shaped fixed block that can move along its length direction. The fixed block is located below the fixed plate and is perpendicular to the filter opening. A support plate is vertically provided on the fixed block. A plurality of first hole cleaning rods are vertically provided on the support plate. The diameter of the first hole cleaning rods is smaller than the smallest diameter mesh hole on the filter screen. The plurality of first hole cleaning rods on the support plate correspond to a set of mesh holes on the first filter screen. During hole cleaning, the support plate moves to the set of mesh holes that need to be cleaned, and the fixed plate moves toward the first filter screen until the first hole cleaning rods pass through the mesh holes of the first filter screen one by one to clean the holes.

[0012] Preferably, the number of the first filter screens is three, and in any two adjacent first filter screens, the first filter screen with the smaller mesh diameter has more mesh holes than the first filter screen with the larger mesh diameter.

[0013] The support plate is provided with a plurality of second cleaning rods and a third cleaning rod. The length of the second cleaning rod is less than the length of the first cleaning rod, and the length of the third cleaning rod is less than the length of the second cleaning rod.

[0014] Preferably, the fixed block is provided with a sliding rod that can move left and right relative to it, and a second telescopic motor is provided on the outer side of one side wall of the dust cover. The output shaft of the second telescopic motor slides through the dust cover and is connected to the sliding rod to drive the fixed block to reciprocate along the fixed plate.

[0018] This utility model has at least the following beneficial effects:

[0019] This invention utilizes a movable scraper to promptly remove dust or impurities from the first filter screen, preventing clogging and improving heat dissipation for the generator set. Furthermore, the use of multiple first filter screens with varying mesh sizes enables multi-stage dust filtration, enhancing filtration efficiency, reducing clogging, and adapting to different environments, thus broadening the application range of the generator set dustproof device. The invention also incorporates a first telescopic motor, an opening, and a push-pull rod to drive the drive plate up and down, thereby moving the scraper along the relative first filter screen. The drive cavity facilitates maintenance of the first telescopic motor and prevents it from overheating during operation, which could affect the dustproof cover's heat dissipation.

[0020] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0025] like Figure 1-3 As shown, this utility model provides a dust prevention device for generator sets, comprising:

[0026] A dust cover 1 is installed on the generator set. One end of the dust cover 1 is provided with an air inlet 2 and the other end is provided with an air outlet. A fan is provided at the air outlet to promote the airflow inside the dust cover 1 and improve the heat dissipation effect.

[0027] The filtration mechanism includes a mounting block 3 detachably connected to the air inlet 2. The mounting block 3 has a filter port 4 at its lower part. Multiple first filter screens 5 are sequentially mounted on the filter port 4 along its depth direction (i.e., towards the inside of the dust cover 1). The mesh size of the first filter screens 5 decreases sequentially along the depth direction of the filter port 4. The portion of the mounting block 3 located below the filter port 4 is connected to a dust collection chamber 20 to collect impurities on the first filter screens 5. The first filter screens 5 are provided with a scraper 15 that can move up and down relative to them.

[0028] In this technical solution, the dust cover 1 is rectangular. One side wall of the dust cover 1 has an air inlet 2, and the other side wall has an air outlet. The dust cover 1 has an adjustment port with an openable second cover to allow operators to operate and maintain the generator set without removing the dust cover 1. An mounting plate 11 is mounted on the mounting block 3 and is bolted to the dust cover 1. The filter port 4 is rectangular. Multiple first filter screens 5 are spaced apart and vertically arranged. The mesh diameters on the mesh 5 are equal, but the mesh diameters on any two adjacent first filter screens are different, and the diameter of the first filter screen 5 decreases along the depth direction of the filter opening 4 to achieve multi-stage filtration of the air entering the dust cover 1; the top of the dust receiving chamber 20 is provided with multiple dust discharge ports 17, and the multiple dust discharge ports 17 are arranged one-to-one with multiple first filter screens 5. Each first filter screen 5 corresponds to a scraper plate 15 that can move up and down. A second filter screen 30 can be set at one end of the filter opening 4 outside the filter opening 4. The second filter screen 30 is flush with the first filter screen 5. The filter is initially filtered; the scraper 15 matches the first filter screen 5 to ensure that the dust accumulated on the first filter screen 5 can be scraped off; a first mounting port can be provided on one side of the mounting block 3, which communicates with the filter port 4. A support frame 16 with open ends is provided inside the filter port 4. A second mounting port is provided on the side wall of the support frame 16. A third cover that can be opened and closed is provided at the second mounting port. The first filter screen 5 is located inside the support frame 16. The first filter screen 5 and the support frame 16 are detachably connected. The detachable connection can adopt existing technology, such as spacing inside the support frame 16. Multiple pairs of U-shaped vertical grooves are provided (two groove openings in each pair are arranged opposite each other). One groove in each pair is located at the top of the support frame 16, and the other is located at the top of the support frame 16. The grooves are arranged along the extension direction of the first filter screen 5. The first filter screen 5 is placed between a pair of grooves through the first mounting port and the second mounting port. The support frame 16 is provided with multiple ash discharge ports 17. The top of the ash receiving chamber 20 is connected to multiple ash inlets 18. Both the ash inlets 18 and the ash discharge ports 17 are elongated to facilitate the collection of dust or impurities on the first filter screen 5.

[0029] During use, the dust or impurities on the first filter screen 5 can be removed in a timely manner by manually or by motor-driven up-and-down movement of the scraper plate 15. Alternatively, the scraper plate 15 can be set to move up and down once every certain time interval (half an hour, one hour, or two hours, etc.).

[0030] By adopting this technical solution, the present invention can promptly remove dust or impurities from the first filter screen 5 by setting a scraper plate 15 that can move up and down, so as to avoid clogging the mesh of the first filter screen 5 and improve the heat dissipation effect of the generator set. The present invention can achieve multi-stage filtration of dust by setting multiple first filter screens 5 with different mesh sizes. This setting can not only improve the filtration effect and reduce the clogging of the mesh, but also be applicable to different environments, thereby increasing the application range of the generator set dust prevention device.

[0031] In another technical solution, the portion of the mounting block 3 located above the filter port 4 has a drive cavity 12. The drive cavity 12 contains a drive plate 13 that can slide vertically relative to it (two first slide rails are vertically arranged within the drive cavity 12, each with a first slider connected to the drive plate 13 to allow the drive plate 13 to slide vertically relative to the drive cavity 12). The drive plate 13 has multiple pairs of drive rods 14 (each pair of drive rods 14 connects to a scraper plate 15, and the drive plate 13 is vertically arranged). The multiple pairs of drive rods 14 correspond one-to-one with the multiple scraper plates 15, and the drive rods 14 slide through the bottom of the drive cavity 12 in a sealed manner and connect to the scraper plates 15. By adopting this technical solution, the present invention, through the setting of the drive cavity 12, facilitates the vertical movement of the scraper plates 15, and on the other hand, the drive rods 14 are sealed and slidably connected to the drive cavity 12 to prevent unfiltered air from directly entering the dust cover 1.

[0032] In another technical solution, the mounting block 3 is provided with an elongated opening 9 (the opening 9 is vertically arranged), the opening 9 is connected to the drive cavity 12, and the mounting block 3 is provided with a first telescopic motor 7 (the first telescopic motor 7 is located outside the mounting block 3). The output shaft end of the first telescopic motor 7 is provided with an L-shaped push-pull rod 8 (the horizontal side of the push-pull rod 8 is connected to the output shaft of the first telescopic motor 7, and the vertical side is connected to the drive plate 13). One side of the push-pull rod 8 slides up and down through the opening 9, and the other end is connected to the drive plate 13 to drive the drive plate 13 to move up and down. With this technical solution, the present invention drives the drive plate 13 to move up and down by setting the first telescopic motor 7, the opening 9, and the push-pull rod 8, thereby driving the scraper plate 15 to move up and down relative to the first filter screen 5. At the same time, by setting the drive cavity 12, it is not only convenient for the maintenance of the first telescopic motor 7, but also avoids the first telescopic motor 7 from overheating during operation, which would affect the heat dissipation effect of the dust cover 1.

[0033] In another technical solution, the mesh on the first filter screen 5 is divided into multiple groups along the horizontal direction, that is, each group contains multiple meshes.

[0034] The system also includes a cleaning assembly, comprising a fixed plate 23 located inside the dust cover 1 and movable relative to the dust cover 1 (the fixed plate 23 can move toward or away from the dust cover 1). The fixed plate 23 is arranged along the length of the first filter screen 5. The fixed plate 23 has a long, movable fixing block 24 along its length (the fixed plate 23 has a second slide rail, and the second slide rail has a second slider; the fixing block 24 is connected to the second slider to achieve a sliding connection between the fixing block 24 and the fixed plate 23). The fixing block 24 is located below the fixed plate 23 and is perpendicular to the filter port 4. A support plate 26 is vertically mounted on the fixing block 24 (the support plate 26 is located below the fixing block 24). Multiple first cleaning rods 27 are vertically mounted on the support plate 26 (the first cleaning rods 27 are perpendicular to the support plate 26). The diameter of the first cleaning rods 27 is... The first cleaning rod 27 is smaller than the smallest diameter mesh on the filter screen (the first cleaning rod 27 can pass through multiple mesh holes on the first filter screen 5 in sequence). The multiple first cleaning rods 27 on the support plate 26 correspond to a set of mesh holes on the first filter screen 5. During cleaning, the support plate 26 moves to the set of mesh holes that need to be cleaned, and the fixing plate 23 moves toward the first filter screen 5 until the first cleaning rods 27 pass through the mesh holes of the first filter screen 5 one by one for cleaning. In use, firstly, the support plate 26 is driven manually or by a motor to move to the set of mesh holes that need to be cleaned, and then the fixing plate 23 is driven to move toward the filter port 4. The first cleaning rods 27 pass through multiple mesh holes on the first filter screen 5 in sequence. After cleaning, the drive plate 13 is driven away from the filter port 4 to move until the first cleaning rods 27 are separated from the first filter screen 5. Then, the support plate 26 is moved along the length direction of the fixing plate 23 to another set of mesh holes. By adopting this technical solution, this utility model achieves hole cleaning without affecting airflow (without stopping the machine) by setting a first hole cleaning rod 27, a fixing plate 23, and a fixing block 24, thereby effectively improving the heat dissipation effect.

[0035] In another technical solution, the number of the first filter screen 5 is three, and for any two adjacent first filter screens 5, the first filter screen 5 with a smaller mesh diameter has more mesh holes than the first filter screen 5 with a larger mesh diameter.

[0036] The support plate 26 is provided with multiple second cleaning rods 28 and third cleaning rods 29. The length of the second cleaning rod 28 is less than the length of the first cleaning rod 27, and the length of the third cleaning rod 29 is less than the length of the second cleaning rod 28. Using this technical solution, the present invention, by setting the number of mesh holes on the first filter screen 5 to increase sequentially, can effectively ensure the amount of air entering and effectively improve the heat dissipation effect. By setting the second cleaning rods 28 and third cleaning rods 29, it is possible to clean all the mesh holes in a group on the first filter screen 5 during cleaning. In the innermost first filter screen 5, some mesh holes are passed through by the first cleaning rod 27, some by the second cleaning rod 28, and the remaining mesh holes are passed through by the third cleaning rod 29. In the middle first filter screen 5, some mesh holes are passed through by the first cleaning rod 27, and the remaining mesh holes are passed through by the second cleaning rod 28. In the outermost first filter screen 5, all mesh holes are passed through one-to-one by the first cleaning rod 27.

[0037] In another technical solution, the fixed block 24 is provided with a sliding rod 25 on its side, which can move left and right relative to it (the sliding rod 25 is stationary relative to the dust cover 1, the fixed block 24 can move left and right, and the sliding rod 25 is parallel to the fixed plate 23). A second telescopic motor is provided on the outer side of one side wall of the dust cover 1. The output shaft of the second telescopic motor slides through the dust cover 1 and is connected to the sliding rod 25 to drive the fixed block 24 to reciprocate along the fixed plate 23. Using this technical solution, the present invention achieves the movement of the fixed block 24 along the fixed plate 23 by setting a second telescopic motor.

[0038] In another technical solution, a third telescopic motor 10 is provided on the mounting block 3 (the telescopic direction of the third telescopic motor 10 is perpendicular to the mounting block 3). The output shaft of the third telescopic motor 10 slides through the mounting block 3 in a sealed manner and is connected to the fixing plate 23 to drive the fixing plate 23 to move toward or away from the filter port 4. By adopting this technical solution, the present invention achieves the movement of the fixing plate 23 toward or away from the filter port 4 by setting the third telescopic motor 10. Furthermore, the third telescopic motor 10 is located outside the mounting block 3, which not only facilitates the maintenance of the third telescopic motor 10 but also reduces the impact of the heat generated by the third telescopic motor 10 on the generator set.

[0039] In another technical solution, the mounting block 3 is provided with a dust removal port 6, which communicates with the dust receiving cavity 20. The dust removal port 6 is provided with an openable and closable first cover. The bottom end of the dust receiving cavity 20 is inclined to facilitate dust removal (the dust removal port 6 is located at the lower end of the dust receiving cavity 20). An inclined dust guide plate 21 is provided inside the dust receiving cavity 20, with the inclination direction of the guide plate 21 opposite to the inclination direction of the bottom end of the dust receiving cavity 20. An inclined guide plate 19 is provided at the dust inlet 18. This technical solution facilitates timely removal of dust or impurities from the dust receiving cavity 20, and the guide plate 19 reduces dust overflow from the dust receiving cavity 20.

[0040] In another technical solution, a third filter is provided at the air outlet. This technical solution reduces the amount of dust entering the dust cover 1.
