Description

Technical Field

[0001] This utility model relates to the field of generator set auxiliary equipment technology, specifically a noise reduction cover for a diesel generator set that is easy to maintain. Background Technology

[0002] Diesel generator sets, as commonly used emergency power supply equipment, are widely used in industries, construction, and communications. To reduce noise pollution during operation, they are usually equipped with soundproof enclosures. Existing soundproof enclosures mostly adopt an integral or flip-top structure, which has the following drawbacks: First, maintenance requires complete disassembly or lifting of the heavy top cover, which is cumbersome, time-consuming, and labor-intensive. This is especially true for large diesel generator sets, whose soundproof enclosures are large and heavy, making manual operation difficult and severely impacting maintenance efficiency. Second, the enclosure lacks a buffer mechanism during opening and closing, making it prone to damage to components due to collisions. Third, the enclosure is inconvenient to move, making it difficult to adjust to the optimal operating position during maintenance.

[0003] To address the aforementioned issues, this utility model proposes a quiet cover for diesel generator sets that facilitates maintenance. By optimizing the top cover structure design, it enables rapid opening and closing, and by adding auxiliary mechanisms, it reduces operational difficulty and improves maintenance convenience. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A noise-reducing cover for a diesel generator set that is easy to maintain includes a cover body, a top cover body, and a cover body comprising two symmetrically arranged and slidably mounted cover plates. The top of the cover body has sliding grooves on its front and rear sides. The sliding grooves are inverted T-shaped structures, including a central groove and side grooves. Sliding blocks are provided on the front and rear sides of the inward-facing end of each cover plate, corresponding to the positions of the sliding grooves. Each sliding block includes a support plate, and sliding rods are symmetrically arranged on the front and rear sides of the support plate. The sliding rods slide within the side grooves, and the support plate slides within the central groove. The outward-facing end of each side groove is closed.

[0006] Preferably, the two cover plates are provided with a pin and a slot on opposite sides respectively.

[0007] Preferably, the front inner wall and the rear inner wall of the top of the cover are respectively provided with a buffer mechanism. The buffer mechanism includes a base plate, which is fixedly installed on the inner wall of the cover. A support arm is rotatably installed on the base plate, and an elastic support rod is rotatably installed in the middle of the support arm. The other end of the elastic support rod is rotatably connected to the base plate. When the cover is not placed, the other end of the support arm is higher than the cover.

[0008] Preferably, a roller is rotatably provided at the end of the support arm that contacts the cover plate.

[0009] Preferably, at least one of the rollers is driven by a drive motor, which is fixedly mounted on the inward side of the support arm.

[0010] Preferably, both ends of the front and rear side walls of the cover are provided with electrically controlled telescopic rods that are inclined outwards and upwards, and the extended ends of the electrically controlled telescopic rods are provided with rollers.

[0011] Preferably, the top surface of the chute is provided with rubber pads on both sides of the central chute.

[0012] Preferably, a rubber block is provided at the bottom of the outward-facing end of the cover plate.

[0013] Preferably, the outer side of the roller is provided with anti-slip texture.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts a two-piece symmetrical sliding cover design. The cover can be opened and closed quickly through the cooperation of the slider and the inverted T-shaped groove. Compared with the traditional one-piece top cover, the opening and closing operation is more labor-saving and can be completed by a single person. There is no need to disassemble the whole body during maintenance, which greatly shortens the maintenance preparation time and improves work efficiency.

[0015] The side groove of this utility model forms a longitudinal limit for the sliding rod, and the middle groove forms a lateral guide for the support plate, ensuring that the sliding process of the cover plate is stable and reliable, avoiding deviation or jamming. At the same time, the closed end of the side groove facing outward can prevent the cover plate from slipping off, improving the safety of use.

[0016] The buffer mechanism of this utility model provides elastic support to the cover plate through the support arm supported by the elastic support rod. It plays a buffering role during the sliding opening and closing of the cover plate, reducing the collision and impact between the cover plate and the cover body, reducing component wear, and extending service life. When the cover plate is fully opened, the support arm can provide effective support to the cover plate, avoiding excessive force on the slide groove due to the weight of the cover plate.

[0017] This utility model enables the electric opening and closing of the cover plate by rotating the roller driven by the drive motor, further reducing the intensity of operation.

[0018] The rubber pads in the groove and the rubber blocks at the end of the cover plate of this utility model can play a sealing and buffering role when the cover plate is closed, enhancing the quietness effect and reducing the impact noise when the cover plate is closed.

[0024] like Figure 1-4 As shown, in this embodiment, a noise-reducing cover for a diesel generator set that is easy to maintain includes a cover body 1 welded from steel plates. The inside of the cover body 1 can be lined with a layer of sound-insulating cotton to enhance the noise reduction effect. A cover body 2 is provided at the top opening of the cover body 1. The cover body 2 is composed of two cover plates 21 of the same size. The cover plates 21 are made of lightweight alloy material to reduce weight and facilitate sliding.

[0025] In this embodiment, grooves 3 are welded to the front and rear edges of the top of the cover 1. The grooves 3 have an inverted T-shaped cross-section, with a central groove 31 located in the middle and side grooves 32 symmetrically arranged on both sides. Slider blocks 4 are bolted to the front and rear sides of the bottom surface of the cover plate 21, offset inwards from the center. The support plate 41 of the slider 4 is embedded in the central groove 31, and the sliding rods 42 at both ends of the support plate 41 are respectively embedded in the side grooves 32 on both sides, forming a sliding fit. The outer ends of the side grooves 32 are closed by end plates, limiting the maximum sliding stroke of the cover plate 21.

[0026] In this embodiment, on one side of the two cover plates 21 facing each other, a pin is welded to the side of one cover plate 21, and a slot is opened at the corresponding position of the other cover plate. When the cover plate 21 is closed, the pin is inserted into the slot to enhance the connection sealing.

[0027] In this embodiment, the base plate 51 of the buffer mechanism 5 is fixed to the front and rear inner walls of the top of the cover 1 by bolts. The lower end of the support arm 52 is rotatably connected to the base plate 51 by a pin. The elastic support rod 53 adopts a telescopic rod structure with a return spring, and its two ends are rotatably connected to the middle of the support arm 52 and the base plate 51 by pins, respectively. In its natural state, the elastic support rod 53 lifts the support arm 52, making the upper end of the support arm 52 higher than the top surface of the cover 1. A roller 54 is rotatably mounted on the upper end of the support arm 52 by a pin, and the wheel surface of the roller 54 contacts the bottom surface of the cover plate 21.

[0028] In this embodiment, at least one set of buffer mechanisms 5 has a drive motor 6 bolted to the inner side of the support arm 52. Its output shaft is connected to the wheel axle of roller 54 via a coupling, which can drive roller 54 to rotate and drive cover plate 21 to slide through friction. The outer circumferential surface of roller 54 is provided with anti-slip texture to enhance the friction with cover plate 21.

[0029] In this embodiment, electrically controlled telescopic rods 7 are fixed to the four corners of the front and rear side walls of the cover 1 by bolts. The electrically controlled telescopic rods 7 are electric push rods with their axes tilted outwards and upwards. Rollers 71 are rotatably mounted on the telescopic ends via brackets. When the cover 1 needs to be moved, the electrically controlled telescopic rods 7 extend, and the rollers 71 contact the bottom of the cover plate, supporting the movement of the cover plate. After reaching the desired position, the electrically controlled telescopic rods 7 slowly retract, and the cover plate slowly lowers.

[0030] In this embodiment, rubber pads 8 are attached to the top surfaces of both sides of the middle groove 31 of the slide 3, and rubber blocks 9 are attached to the bottom of the outward-facing end of the cover plate 21. When the cover plate 21 is closed, the rubber pads 8 contact the bottom surface of the cover plate 21, and the rubber blocks 9 contact the side surface of the cover 1, which plays a role in sealing and buffering.

[0031] In this embodiment, the bottom surface of the cover plate corresponding to roller 54 is also provided with anti-slip texture.

[0032] The working principle of the above technical solution is as follows: When the diesel generator set needs maintenance, start the electrically controlled telescopic rod 7 to extend it, then start the drive motor 6 to rotate forward, driving the roller 54 to rotate. Under the action of friction, the two cover plates 21 slide open to both sides along the sliding groove 3. At this time, the support arm 52 of the buffer mechanism 5 always supports the cover plate 21 under the action of the elastic support rod 53. After the cover plate 21 is fully opened, the top opening of the cover 1 is exposed, and maintenance work can be carried out. If it is necessary to move the cover 1, start the electrically controlled telescopic rod 7 to retract it, and the cover plate slowly lowers under the action of gravity. After the maintenance is completed, start the electrically controlled telescopic rod 7 to extend it, lift the cover plate to keep it horizontal, then start the drive motor 6 to reverse it, driving the two cover plates 21 to slide and close in the middle. The pin is inserted into the slot, and the rubber gasket 8 and rubber block 9 achieve sealing and buffering, completing the closing operation. The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
