Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation enclosures, in particular to a photovoltaic automatic temperature-control sound insulation enclosure. Background Art

[0002] With the rapid development of social economy, people's environmental awareness and health awareness are constantly strengthened, and social attention to various environmental pollution is increasing. Among them, noise pollution has become one of the environmental issues that government departments at all levels, enterprises and the general public attach great importance to.

[0003] A soundproof enclosure is a device that places the noise source inside and blocks the noise from propagating outside the enclosure. It can not only isolate the noise of the equipment, but also serve as a control room for high-noise workshops. Using a soundproof enclosure is an effective measure to reduce the noise interference of various types of equipment, and is widely used in noise control of compressors, blowers, motors, water pumps and other equipment. However, due to the coverage of individual mechanical equipment by the soundproof enclosure, heat accumulates in the soundproof enclosure, making it impossible to dissipate the heat generated by the mechanical equipment in time, seriously affecting the reliable operation of the mechanical equipment. Therefore, the problem of achieving sound insulation while taking into account heat dissipation for the soundproof enclosure needs to be solved.

[0004] The utility model patent with the patent application number of "200810165908.2" and the name of "Soundproof enclosure with intelligently controlled sound insulation" discloses a soundproof enclosure with intelligently controlled sound insulation. While solving the ventilation and heat dissipation problems of the noise source, the utility model realizes the comprehensive intelligent and automatic control of the sound insulation of the sound insulation facilities. With regard to this utility model, the installation of the air inlet and the air outlet not only occupies the space of the soundproof enclosure, but also the operation of the centrifugal exhaust fan will generate more noise and consume more electric energy. No sound-absorbing material is used in the structure of the soundproof enclosure, so its sound absorption and sound insulation effects are worse than those of the soundproof enclosure using sound-absorbing materials.

[0005] The utility model patent with application number "202310045658.3" and name "A metal sound-absorbing and sound-insulating cover with automatic temperature control" discloses a metal sound-absorbing and sound-insulating device with automatic temperature control, including a metal sound-absorbing and sound-insulating screen. The utility model overcomes the problem of exhausting the sound-absorbing and sound-insulating cover under negative pressure while meeting the noise reduction requirements of the sound-absorbing and sound-insulating cover, which is conducive to controlling the temperature of the sound-absorbing and sound-insulating device to meet the temperature requirements for the normal operation of mechanical equipment. With respect to the utility model, the low-pitched exhaust fan and temperature control system of the utility model are still powered by the distribution box, and low-carbon energy saving cannot be achieved due to the power consumed, which is not in line with the path of green and low-carbon development.

[0030] See also Figures 4 to 6 In this embodiment, the aluminum square tube 1 is vertically and evenly fixed on the steel structure frame 11 by bolts, a sound insulation door 10 is installed on one side of the steel structure frame 11, a sound insulation board 12 is arranged on the top of the aluminum square tube 1, and a photovoltaic panel 2 is laid on the outside of the sound insulation board 12.

[0031] See also Figure 1In this embodiment, the photovoltaic panel 2 is connected in series with the battery 13, the diode 18, the Hall current sensor 19, and the MPPT controller 22 through a wire, and the current flows through the diode 18, the MPPT controller 22, and the Hall current sensor 19 through the wire into the battery 13 for storage.

The central controller 14 is connected to the temperature sensor 15, the first sound pressure sensor 16, and the second sound pressure sensor 17 through a wire, wherein the temperature sensor 15 and the first sound pressure sensor 16 are arranged on the inner side of the annular steel structure frame 11, and the second sound pressure sensor 17 is arranged on the outer side of the annular steel structure frame 11.

[0032] The first sound pressure sensor 16 and the second sound pressure sensor 17 collect the noise sound pressure, and the collected signals are input into the central controller 14. The central controller 14 calculates the sound pressure level difference, i.e., the sound reduction amount, and monitors whether the required sound reduction amount is reached. The standard of the sound reduction amount should not be less than 15dB.

[0033] The sound pressure level of the external environment is calculated as follows:

[0034]

[0035] Where, △L 1 is the internal sound pressure level, p 1 is the internal sound pressure, p 0 As the reference sound pressure, take 2×10 -5 Pa.

[0036] The calculation method of the sound pressure level of the internal environment is as follows:

[0037]

[0038] Where, △L 2 is the external sound pressure level, p 2 is the external sound pressure, p 0 As the reference sound pressure, take 2×10 -5 Pa.

[0039] The sound pressure level difference is calculated as follows:

[0041] Where △L is the sound pressure level difference.

[0042] In this embodiment, the shell of the muffler sheet 4 is an aluminum perforated plate, which is filled with centrifugal glass wool; it has the function of impedance composite muffler. When the sound wave reaches the aluminum perforated plate on the surface of the muffler sheet 4, part of the incident sound wave is reflected, and the frequency of part of the incident sound wave is consistent with the resonant frequency of the system. The air at the neck of the aluminum perforated plate produces intense vibration friction, forming an absorption peak, which significantly attenuates the medium and low frequency sound waves; the perforated plate is filled with centrifugal glass wool, and the sound wave propagates in the centrifugal glass wool, and the sound energy is converted into heat energy due to friction and dissipated, so that the medium and high frequency sound waves attenuate with distance.

[0043] In this embodiment, the opening and closing angle of the muffler plate 4 is 30° to 90°; the slide rail 6 is configured as an arc structure, and the slider 7 is clamped on the slide rail 6.

When working, the driving motor 9 works, the transmission shaft 8 rotates, and the connecting rod 5 moves along the arc trajectory, and the slider 7 is driven by the connecting rod 5 to move on the slide rail 6, thereby driving the muffler 4 to rotate.

[0045] The minimum opening and closing angle of the silencer plate 4 is 30°, at which the silencer plates 4 are parallel to each other and the intervals are minimal; the maximum opening and closing angle of the silencer plate 4 is 90°, at which the silencer plate 4 is fully opened and loses its silencer function.

[0046] When the utility model is working, the specific working steps are as follows:

[0047] The temperature sensor 15 continuously monitors the temperature, the first sound pressure sensor 16 and the second sound pressure sensor 17 monitor the sound pressure inside and outside the steel structure frame 11 in real time, and the central controller 14 calculates the sound pressure level difference;

[0048] When the internal temperature is lower than 20°C, the central controller 14 sends a signal, the relay 21 conducts the circuit, the transmission shaft 8 of the driving motor 9 rotates, and the connecting rod 5 moves in a circular arc trajectory. The slider 7 is driven by the connecting rod 5 to move on the slide rail 6, and the muffler 4 starts to rotate continuously, and the opening and closing angle continues to decrease until the minimum opening and closing angle is 30°;

[0049] When the internal temperature is between 20°C and 40°C, the central controller 14 sends a signal, the relay 21 conducts the circuit, the transmission shaft 8 of the drive motor 9 rotates, and the connecting rod 5 moves in a circular arc trajectory. The slider 7 is driven by the connecting rod 5 to move on the slide rail 6, and the sound-absorbing plate 4 starts to rotate continuously, increasing the opening and closing angle; after the sound pressure level difference calculated by the central controller 14 drops to 15dB, the central controller 14 immediately sends a signal, the drive motor 9 stops working, and the sound-absorbing plate 4 stops rotating immediately;

[0050] When the internal temperature is higher than 40°C, the central controller 14 sends a signal, the relay 21 conducts the circuit, the transmission shaft 8 of the driving motor 9 rotates, and the connecting rod 5 moves in a circular arc trajectory. The slider 7 is driven by the connecting rod 5 to move on the slide rail 6, and the muffler 4 is directly rotated to 90°.

[0051] After the temperature drops below 40°C, the central controller 14 sends a signal, the relay 21 turns on the circuit, the transmission shaft 8 of the driving motor 9 rotates, and the connecting rod 5 moves in a circular arc trajectory. The slider 7 is driven by the connecting rod 5 to move on the slide rail 6, driving the silencer 4 to reduce the opening and closing angle until the sound pressure level difference reaches 15dB.
