[0002] In daily production and life, especially in places like construction sites, noise is inevitable. Noise is not only harmful to the environment, but also has a great impact on the human body, such as causing tinnitus, hearing loss and other diseases, and also causing people to feel unhappy.

[0003] In order to better control noise, there are now many noise detection devices. In addition to the commonly used handheld noise detectors, there are also desktop noise detection devices that can be used for long-term detection and recording. Their functions are becoming more and more diverse. Some have already achieved automatic prompts or warnings. However, the working environment of the equipment is diverse. When the noise detection device is used in a dusty construction site or on a rainy day, the raised dust or rainwater can easily enter the interior of the noise detection device, causing damage to the components inside the device, and then causing the device to be unable to use normally.

[0004] To solve the above problems, we propose a noise detection device with an automatic prompting device. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 of the embodiments.

[0020] Reference Figure 1-Figure 4 A noise detection device with an automatic prompting device comprises a bottom plate 1, a lifting assembly is arranged above the bottom plate 1, a lifting platform 18 is arranged above the lifting assembly, a battery 8 and a motor 10 located on one side of the battery 8 are fixedly installed below the lifting platform 18, a through hole corresponding to the driving end of the motor 10 is opened on the outer wall of the lifting platform 18, the driving end of the motor 10 is inserted into the through hole, and the end extends upwardly out of the upper side wall of the lifting platform 18, a solar cell panel 9 is fixedly installed on the upper side of the lifting platform 18, and the driving end of the motor 10 is fixedly sleeved. There is a main gear 12 located on the upper side of the lifting platform 18, and a driven gear 13 meshing with the main gear 12 is rotatably provided on the upper side wall of the lifting platform 18. A protective cover 14 is fixedly installed on the upper wall of the driven gear 13. The outer wall of the protective cover 14 is provided with a plurality of openings, and metal filters 15 are provided on the openings. A rain cover 16 is fixedly installed on the top of the protective cover 14, and a speaker 17 is fixedly provided on the top of the rain cover 16. When the volume of external noise reaches or exceeds the preset decibel range of the noise detection element, the speaker will automatically make a sound to prompt.

[0021] A jack 3 is fixedly installed on the base plate 1, and the lifting assembly includes a jack 3, a push rod 4, a rod 1 6, a rod 2 7, and a rotating shaft 5. The driving end of the jack 3 is fixedly connected to the push rod 4. Two slide grooves 19 are symmetrically provided on the upper part of the base plate 1. The push rod 4 is slidably inserted in the two slide grooves 19. The push rod 4 is rotatably connected to the two rods 1 6. The lower ends of the two rods 27 are rotatably connected to the base plate 1. The two rotating shafts 5 are fixedly connected to the middle parts of the rods 2 7. The middle parts of the two rods 1 6 are rotatably connected to the rotating shaft 5. The lower end of the lifting platform 18 is symmetrically provided with two slide grooves 20. The upper ends of the two rods 6 are slidably inserted in the slide grooves 20. The upper ends of the two rods 27 are rotatably connected to the base plate 1. The first end is rotatably connected to the other end of the lifting platform 18. When the height needs to be increased, the jack 3 is operated to shrink the driving end of the jack 3, driving the push rod 4 to slide inside the slide groove 19. The lower ends of the two rods 16 rotatably sleeved on the outer wall of the push rod 4 gradually approach the rotating connection between the rod 2 7 and the base plate 1. At the same time, a rotating shaft 5 is fixedly installed in the middle of the rod 2 7. The rod 1 6 is rotatably connected to the rotating shaft 5. When the lower end of the rod 1 6 gradually approaches the lower end of the rod 2 7 in the horizontal direction, the upper end of the rod 1 6 also gradually approaches the upper end of the rod 2 7 in the horizontal direction. Then, the height of the rod 1 6 and the rod 2 7 in the vertical direction increases, and the lifting platform 18 can be increased.

[0022] The protective cover 14 is in the shape of a cylinder, and the upper and lower end faces of the cylinder are in the shape of rounded squares. The outer wall of the protective cover 14 is provided with a plurality of openings arranged at equal distances, and a metal filter 15 is fixedly arranged on the outer wall of each opening, and the surface where the opening is located is on the arc surface of the outer wall of the cylinder. Two brushes 11 are fixedly installed on the upper side of the lifting platform 18, and the two brushes 11 are symmetrically arranged on both sides of the protective cover 14. Figure 3 When the protective cover 14 rotates, the two brushes 11 can intermittently brush the surface of each metal filter 15 to prevent dust accumulation. The length of the soft bristles on the brushes 11 can make the surface swept by the brushes 11 coincide with the arc surface where the metal filter 15 is located when the protective cover 14 rotates, while at the same time preventing the brushes 11 from contacting other surfaces of the protective cover 14.

[0023] The four corners of the base plate 1 are fixed with fixing nails 2. The shape of the fixing nails 2 is set to be conical, and the material is set to be stainless steel. When it is on a softer ground, such as mud, the fixing nails 2 are driven into the ground, which can make the whole device stand more firmly on the ground.

[0024] The cross-sectional shape of the rainproof cover 16 is set to be circular, and the protective cover 14 and the brush 11 are both arranged directly below the rainproof cover 16. When it rains, the rainproof cover can shield the protective cover 14 and the brush 11, so that rainwater will not flow into the interior of the device.

[0025] When in use, first stabilize the base plate 1, drive the fixing nails 2 into the ground and fix them, then adjust the height of the lifting platform 18, turn on the motor 10, and the driving end of the motor 10 drives the main gear 12 to rotate, and the main gear 12 drives the driven gear 13 to rotate, and the driven gear 13 rotates synchronously with the protective cover 14. The protective cover 14 is a cylinder with a rounded square cross-section. The four arc-shaped surfaces of the protective cover 14 are opened as through holes, and the metal filter 15 is installed on these through holes. When the protective cover 14 rotates, the two brushes 11 can continuously sweep the surface of the metal filter 15 to prevent dust from accumulating on the surface of the metal filter 15. The length of the soft bristles on the brush 15 can just touch the arc surface on the column of the protective cover 14, that is, the length of the brush can just touch the metal filter 15, and only the metal filter 15 is cleaned without contacting other surfaces of the protective cover 14 (refer to Figure 3 ), which increases the cleaning efficiency and the service life of the brush. A rain cover 16 is fixedly installed on the top of the protective cover 14. The rain cover 16 can completely cover the protective cover 14 and the brush 11 to protect the noise detection element, thereby preventing the raised dust or rain from entering the interior of the protective cover 14, thereby extending the service life of many electronic components inside the protective cover 14. When the volume of external noise reaches or exceeds the preset decibel range of the noise detection element, the speaker will make a sound to prompt.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
