Description

Technical Field

[0001] The present invention relates to the technical field of sand collectors, in particular to a multi-directional sound wave conversion sand collector. Background Art

[0002] Sandstorms have always been a major challenge to development and ecological protection in desert regions. All types of sandstorm hazards are caused by wind-blown sand activity. Therefore, engineering control of sandstorms requires understanding the characteristics and intensity of regional sandstorm activity. Accurately measuring the intensity of sandstorm activity in arid desert regions is crucial for developing regional sandstorm control plans, establishing comprehensive sandstorm protection systems, improving the living conditions of farmers and herdsmen in these regions, and safeguarding the ecological security of desert oases.

[0003] At present, sand collectors are generally used to observe the amount of sand carried by wind and sand flows. One type of sand collector only collects sand particles, which are then weighed manually, making the operation complicated. Another type of sand collector is equipped with a weighing sensor, which directly weighs the sand particles after collecting them. However, the sand particles already collected in the sand collector need to be cleaned manually. Another type of sand collector uses sand particles to hit the sensor, and uses the effect of the sand particles on the electric current to obtain the number and energy of the sand particles. However, this method has the disadvantage that only sand particles within a fixed particle size range can be recorded, and sand particles exceeding the particle size range cannot be recorded. Summary of the Invention

[0004] The purpose of the present invention includes providing a multi-directional sand collector for acoustic wave conversion, which can detect wind and sand activities in all directions, is not limited by the particle size of sand particles, does not require manual weighing, and is convenient and easy to use.

[0007] Bracket;

[0008] Multiple collection boxes are arranged at intervals around the bracket. The collection boxes include air inlets, which are facing away from the bracket. An acoustic wave sensor is provided at the bottom of the collection box. The acoustic wave sensor is used to convert the sound waves generated by the impact of sand particles into electrical signals.

[0009] Multiple wind speed sensors, one on each side of each collection box, are used to detect the speed of the wind and sand flow entering the collection box;

[0010] The processor is electrically connected to the acoustic wave sensor and the wind speed sensor. The processor is used to count the electrical signals to form an acoustic wave spectrum, and count the number a of sand grains entering the collection box and the mass m of a single sand grain based on the acoustic wave spectrum and the speed, and calculate the total mass M of the sand grains based on the number a and the mass m.

[0011] In an optional embodiment, the collection box comprises a side wall and a bottom wall, the side wall is trumpet-shaped and opens away from the support, one end of the side wall forms an air inlet, the other end of the side wall is connected to the bottom wall, and the acoustic sensor is mounted on the bottom wall.

[0012] In an optional embodiment, the angle between the bottom of the side wall and the vertical plane is less than 45°, and the bottom of the side wall is used to guide the sand particles entering the collection box to fall out of the collection box under the action of gravity.

[0013] In an optional embodiment, the bottom wall is made of a hard material and is used to collide with the sand particles and form acoustic waves.

[0014] In an optional embodiment, the support comprises:

[0015] a vertical rod fixedly connected to the vertical rod, the vertical rod being used to support on the ground;

[0016] a plurality of horizontal rods, each horizontal rod being fixedly connected to the bottom wall.

[0017] In an optional embodiment, the number of collection boxes is eight, and the arrangement of the eight collection boxes is a regular octagon.

[0018] In an optional embodiment, the processor is used to derive the number of sand particles a according to the number of wave crests b of the acoustic spectrum, and derive the mass m of a single sand particle according to the amplitude A and the speed of a single wave crest of the acoustic spectrum.

[0019] In an optional embodiment, the number of wave crests b of the acoustic spectrum is equal to the number of sand particles a, and the amplitude A of a single wave crest is positively correlated with the energy P of a single sand particle.

[0020] In an optional embodiment, the calculation formula of the mass m of a single sand particle is:

[0021] m = P / v

[0022] In the formula, v is the speed of the sand particles, and the speed of the sand particles is equal to the speed of the wind-sand flow.

[0023] The calculation formula of the total mass M of the sand particles is:

[0024] M = m1 + m2 + … + mn

The number of peaks in the acoustic wave spectrum can reflect the number of sand particles, and the amplitude of the peaks in the acoustic wave spectrum can reflect the energy of the sand particles. The mass of a single sand particle can be calculated from the energy of the sand particles, and thus the total mass of the sand particles that hit the acoustic wave amplifier in a specific time period can be calculated, thus serving as a sand collector.

[0032] 3. The working process of the acoustic wave conversion multi-directional sand collector does not require human participation, for example, there is no need for manual collection and weighing of sand on a regular basis.

[0043] Please refer to Figure 1 This embodiment provides a multi-directional sand collector 100 for acoustic wave conversion, which includes a bracket 110, a collection box 120, an acoustic wave sensor 130, a wind speed sensor 140, a processor 150, a solar panel 160, and a battery 170.

[0044] Specifically, the support 110 includes a vertical pole 111 and multiple horizontal poles 112. The vertical pole 111 is used for ground support; each horizontal pole 112 is fixedly connected to the end of a collection box 120. In this embodiment, there are eight collection boxes 120, arranged in a regular octagon. The air inlets of the collection boxes 120 face away from the support 110, allowing each collection box 120 to collect sand in its own direction, achieving comprehensive monitoring of wind and sand activity.

[0045] The acoustic wave sensor 130 is installed at the bottom of the collection box 120 , and is used to convert the acoustic waves generated by the impact of sand particles into electrical signals.

[0046] The processor 150 is electrically connected to the acoustic wave sensor 130 . The processor 150 is used to count the electrical signals to form an acoustic wave spectrum, and to count the number a of sand particles entering the collection box 120 and the amplitude A of a single wave peak based on the acoustic wave spectrum.

[0047] Because the number of peaks b in the acoustic spectrum can reflect the number of sand grains a, a sand grain hitting the bottom of the collection box 120 will form a peak in the acoustic spectrum. In this way, the number of peaks b in the acoustic spectrum is equal to the number of sand grains a.

[0048] Furthermore, the peak amplitudes A formed by sand particles of different energies impacting the bottom of the collection box 120 vary. Thus, the amplitude A of a single peak in the acoustic spectrum can reflect the energy P of a single sand particle. Specifically, the amplitude A of a single peak is positively correlated with the energy P of a single sand particle. Furthermore, the energy P of a single sand particle is proportional to its mass m. Therefore, the mass m of a single sand particle can be inferred. Given the number a of sand particles previously calculated, the total mass M of the sand particles can be calculated.

[0049] The calculation formula for the mass m of a single sand particle is:

[0050] m=P / v

[0051] Wherein, v is the velocity of the sand particles, which is equal to the velocity of the wind and sand flow. A wind speed sensor 140 is installed on one side of each collection box 120 to detect the velocity of the wind and sand flow entering the collection box 120 .

[0052] The total mass M of sand particles is calculated as follows:

[0053] M=m1+m2+…+mn

[0054] Where m1, m2…mn are the masses of n grains of sand respectively.

[0055] The solar panel 160, the battery 170, and the processor 150 are electrically connected in sequence. The solar panel 160 is used to convert solar energy into electrical energy and store it in the battery 170. The battery 170 is used to supply power to the processor 150. In this way, even if the multi-directional acoustic wave conversion sand collector 100 of this embodiment is installed and used outdoors, it can achieve self-sufficiency in electrical energy through the solar panel 160 and the battery 170, which is conducive to the long-term and stable use of the multi-directional acoustic wave conversion sand collector 100.

[0056] Of course, in other embodiments, the processor 150 can be provided with an external plug for connecting to a power source to obtain electrical energy.

[0057] Referring to Figure 2 The collection box 120 includes a side wall 121 and a bottom wall 122. The side wall 121 is trumpet-shaped and has an opening direction facing away from the support 110. One end of the side wall 121 forms an air inlet, and the other end of the side wall 121 is connected to the bottom wall 122. The sound wave sensor 130 is mounted on the bottom wall 122. The bottom wall 122 is made of a hard material and is used to collide with sand particles and form sound waves.

[0058] The angle J between the bottom of the side wall 121 and the vertical plane is less than 45°. The bottom of the side wall 121 is used to guide the sand particles entering the collection box 120 to fall out of the collection box 120 under the action of gravity.

[0059] The sound wave conversion multi-directional sand collector 100 provided by the embodiments of the present application has the following beneficial effects:

[0060] 1. A plurality of collection boxes 120 are arranged at intervals around the support 110. The air inlets of the collection boxes 120 face away from the support 110, so that each collection box 120 can collect wind sand from a respective direction, thereby achieving omnidirectional detection of wind sand activity.

[0061] 2. The bottom of the collection box 120 is provided with a sound wave sensor 130. The sound wave sensor 130 can convert the sound waves generated by the collision of sand particles into electrical signals. The processor 150 can count the electrical signals to form a sound wave spectrum. The number of wave crests in the sound wave spectrum can reflect the number of sand particles, and the amplitude of the wave crests in the sound wave spectrum can reflect the energy of the sand particles. The energy of the sand particles can be used to calculate the mass of a single sand particle, thereby calculating the total mass of the sand particles colliding with the sound wave amplifier in a specific time period, thereby achieving the function of a sand collector.

[0062] 3. The working process of the sound wave conversion multi-directional sand collector 100 does not require human intervention, such as regular collection of sand particles for weighing. The sound wave conversion multi-directional sand collector 100 is convenient to use and is suitable for almost all particle size ranges of sand particles, as long as the sand particles can collide with the inside of the collection box 120 to produce sound.

[0063] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed by the present application can be easily thought of by those skilled in the art, and should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
