[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0024] An embodiment of the present application provides a gas manhole cover that is powered by sound energy recovery.

[0025] Embodiment 1, as Figure 1 shown.

[0026] A gas manhole cover for power supply by sound energy recovery comprises a manhole cover body 1, which covers the road surface. The manhole cover body 1 is the main structure of the entire technical solution and is usually made of solid materials.

[0027] A manhole cover liner block 2 is installed below the manhole cover body 1, and a manhole cover liner 3 is installed inside the manhole cover liner block 2. The manhole cover liner 3 is in a water drop shape, so that the manhole cover liner 3 is a closed space, ensuring that sound waves and vibrations can be effectively captured and converted. A connecting member 4 is installed between the manhole cover body 1 and the manhole cover liner 3. The manhole cover body 1 is affected by ground vibration or sound waves, which can be directly transmitted to the manhole cover liner 3.

[0028] The inner liner block 2 of the manhole cover is internally installed with an acoustic energy recovery module 5 and a power module 6, the acoustic energy recovery module 5 and the power module 6 are connected via a circuit, and the acoustic energy recovery module 5 converts mechanical vibration into electric charge through the piezoelectric effect, and then stores it in the power module 6. The voltage type of the power module 6 is DC-DC, and the power module 6 includes an energy storage battery and a power control device, the model of the energy storage battery is DM21, and the model of the power control device is STM32F0.

[0029] The electric energy generated by the acoustic energy recovery module 5 is stored in the power module 6, and the electric energy inside the power module 6 is supplied to the equipment in the gas well. The power module 6 is a DC voltage, and the common DC voltage is 5V (4.5-9V), which outputs the electric energy of the power module 6 to the equipment in the gas well smoothly.

[0030] The sound energy recovery module 5 includes a thin film vibration device 51 , a sound wave sensor 52 , a vibration sensor 53 , and a charge amplifier 54 .

[0031] The thin film vibration device 51 is coated on the surface of the manhole cover liner 3, and converts mechanical vibration into electric charge through the piezoelectric effect. The thin film vibration device 51 is a piezoelectric material, such as piezoelectric ceramics or polymers, which have a piezoelectric effect. When the film vibrates, the piezoelectric material undergoes a slight deformation, resulting in the separation of positive and negative charges, forming a battery difference, and then forming a current, which flows through the circuit and into the power module 6 for storage.

[0032] The acoustic wave sensor 52 is installed on the surface of the manhole cover inner liner 3 to capture the sound waves and convert them into electrical energy. The model of the acoustic wave sensor 52 is HC-SR04. The vibration sensor 53 is installed on the surface of the manhole cover inner liner 3 to detect the vibration of the manhole cover. The model of the vibration sensor 53 is RS-485.

[0033] The vibration sensor 53 and the acoustic wave sensor 52 , as well as the acoustic wave sensor 52 and the power module 6 are connected via circuits.

[0034] The vibration sensor 53 controls the working state of the acoustic wave sensor 52. When the vibration sensor 53 detects a vibration signal, the acoustic wave sensor 52 is controlled to start, collect acoustic energy, and convert it into electrical energy.

[0035] The charge amplifier 54 is installed inside the manhole cover inner block 2 and is connected to the thin film vibration device 51 and the power module 6 through a circuit. The charge amplifier 54 enhances the charge generated by the thin film vibration device 51 and then introduces it into the power module 6 for storage.

[0036] When the utility model is in use:

[0037] When urban traffic or other activities generate sound waves, the vibration sensor 53 detects the vibration signal and controls the start of the sound wave sensor 52. The sound wave sensor 52 and the vibration sensor 53 work simultaneously to capture these sound waves and vibration signals.

[0038] The film vibration device 51 converts the captured sound waves and vibrations into electrical energy, which is further amplified by the charge amplifier 54 and finally introduced into the power module 6, where the electrical energy is stored in the energy storage battery.

[0039] According to the needs of the equipment in the gas valve well, the electric energy stored in the power module 6 provides a stable power output to supply the equipment or other equipment in the well.
