Abstract
Description
Technical Field
[0001] This utility model relates to the field of rainproof equipment technology, and more specifically, to a piezoelectric induction rainproof device. Background Technology
[0002] During the rainy season, accurate rainfall estimation is crucial for the effective implementation of rain and flood prevention measures. However, current practices often suffer from inaccurate rainfall estimates, leading to inadequate rain and flood prevention measures for related shelters, resulting in water ingress and flooding losses. Manual rain protection measures are also affected by the uncertainty of personnel availability, making it difficult to ensure timely protection and causing property damage. Real-time monitoring of rainfall for prevention and control is a feasible means to reduce costs and solve flood and waterlogging problems.
[0003] The piezoelectric effect is a special physical phenomenon where certain non-conductive materials develop electrical charges on their surface when subjected to mechanical loads, thus becoming conductive. Utilizing this property of piezoelectric materials, the mechanical energy generated when a rain shelter is subjected to raindrop impacts or other external forces can be converted into electrical energy. When raindrops fall on the rain shelter, the piezoelectric material deforms under pressure, generating electrical charges or voltages. Collecting and statistically analyzing the continuous charge and voltage data to activate or deactivate flood control equipment in real time and control its capacity is a reasonable method.

Example
[0029] This embodiment provides a piezoelectric sensing rainproof device 100, referencing... Figure 1 As shown, it includes a canopy with an inclined top plate 110 that slopes downward along its width to form a relatively high first side 111 and a relatively low second side 112.
[0030] The upper surface of the top plate 110 is provided with a piezoelectric detection unit (not shown in the figure) made of piezoelectric material; it should be noted that the piezoelectric material can cover the entire upper surface of the top plate 110 or only a local area, as long as it can achieve the corresponding detection effect. At the same time, the surface of the piezoelectric detection unit can be coated with a sun-proof and anti-corrosion coating to extend its service life.
[0031] like Figure 1 and Figure 2 As shown, an extension plate 120 is provided at the bottom of the top plate 110. The extension plate 120 is slidably engaged with the top plate 110 and can slide from the first side 111 to the second side 112 under the action of gravity. A first electromagnet 113 for attracting the extension plate 120 is also provided at the bottom of the top plate 110. The first electromagnet 113 is located at the higher end of the top plate 110. The piezoelectric induction rainproof device 100 also includes a power supply module for supplying power to the first electromagnet 113, and a control module for controlling the opening and closing of the power supply module. The control module is electrically connected to the piezoelectric detection unit. Under normal circumstances, the entire piezoelectric induction rainproof device 100 is in a powered state. The first electromagnet 113 continuously generates an attractive force to attract the extension plate 120 and retract it under the bottom plate 130. It should be noted that the extension plate 120 can be made of metal so that the first electromagnet 113 can attract it. Alternatively, it can be made of non-metallic material, and a metal block can be installed at the position in contact with the first electromagnet 113 to achieve the same purpose.
[0032] When raindrops fall on the upper surface of the top plate 110, the piezoelectric detection unit deforms under pressure, generating a voltage. When the voltage exceeds a threshold, a signal is sent to the control module, which cuts off the power. This causes the first electromagnet 113 to lose its attraction, and the extension plate 120 slides down under gravity, extending from below the bottom plate 130 to form a larger shielding area, thus better protecting people or objects under the canopy. This piezoelectric sensing rainproof device 100 has a wide range of applications, such as bus stops or material storage areas. Because its rainproof function operates in power-off mode during heavy rain, it can prevent electric shock and provides better safety.
[0033] Both ends of the extension plate 120 along its length are provided with vertically extending vertical partitions 121. The vertical partitions 121 can provide shelter from both sides, further expanding the rain-proof area.
[0034] The top plate 110 has a pair of guide rails (not shown) at both ends along its length. The pair of guide rails are located at the bottom of the top plate 110 and are arranged along the width direction of the top plate 110. The top of the extension plate 120 has a slider 122 that cooperates with the pair of guide rails. The relative sliding between the extension plate 120 and the top plate 110 can be achieved through the cooperation of the guide rails and the slider 122.
[0035] In addition, such as Figure 3 and Figure 4 As shown, a limiting block 114 is also provided at the bottom of the top plate 110. The limiting block 114 is located on the side closer to the second side 112 and is arranged along the length direction of the top plate 110. A protruding rib 123 is provided at the top of the extension plate 120. The protruding rib 123 is located on the side of the extension plate 120 closer to the first side 111 and is arranged along the length direction of the extension plate 120. When the extension plate 120 slides to a certain position, the protruding rib 123 is abutted by the limiting block 114 to prevent the extension plate 120 from falling off completely.
[0036] Furthermore, such as Figure 2 As shown, the canopy also includes a base plate 130, a back plate 140 and a pair of side plates 150 disposed on the base plate 130. The back plate 140 is connected to the first side 111, and the pair of side plates 150 are disposed opposite each other and are respectively connected to both ends of the top plate 110 in the length direction. The top plate 110, the base plate 130 and the pair of side plates 150 together form a rain shelter 160, and an opening 161 is formed on the second side 112. This frame structure can completely cover the top, back and sides, achieving a better shading effect.
[0037] Multiple support columns 131 are evenly distributed at the bottom of the base plate 130. The support columns 131 can raise the base plate 130 as a whole to prevent water from flooding into the rain shelter 160 in the event of flooding. The support columns 131 can extend downwards and be buried in the ground to increase the overall stability.
[0038] Furthermore, the piezoelectric induction rainproof device 100 is also equipped with a flap 170. A rotating shaft 132 is provided on the base plate 130 near the opening 161, and the rotating shaft 132 is arranged along the length of the base plate 130. The middle part of the flap 170 is rotatably connected to the rotating shaft 132 and can be flipped around the rotating shaft 132. The flap 170 includes a water-blocking part 171 away from the first side 111 and a counterweight part 172 near the first side 111. The counterweight part 172 and the water-blocking part 171 are located on opposite sides of the rotating shaft 132. The base plate 130 and / or the side plate 150 are equipped with a second electromagnet 151 for attracting the counterweight part 172. The second electromagnet 151 is electrically connected to the power supply module. In the energized state, the water-blocking part 171 of the flap 170 extends horizontally outward, serving as an outward extension of the base plate 130. In the event of a power outage, the magnetic force of the second electromagnet 151 disappears, and the counterweight 172 sinks under gravity. Utilizing the lever principle, this causes the water-blocking part 171 to flip upwards, sealing the lower half of the opening 161 and preventing water from entering the rain shelter 160. In actual use, different thresholds can be set for the power-off points of the first electromagnet 113 and the second electromagnet 151 in the control module. When rainfall does not pose a risk of flooding, only the power supply to the first electromagnet 113 needs to be disconnected.
[0039] like Figure 2 As shown, the lower end of the side plate 150 is provided with a first abutting surface 152 for abutting against the water-blocking part 171. The first abutting surface 152 is inclined and gradually moves towards the back plate 140 along the direction close to the bottom plate 130. The inclined first abutting surface 152 allows the water-blocking part 171 to generate a horizontal component force under the continuous downward pressure of the counterweight part 172, making the water-blocking part 171 and the first abutting surface 152 fit more tightly. The bottom plate 130 is provided with a second abutting surface 133 for abutting against the water-blocking plate. The first abutting surface 152 and the second abutting surface 133 are provided with a sealing strip 153, which is continuously provided along the edge of the opening 161. The sealing strip 153 further increases the tightness of the water-blocking plate and prevents water from penetrating into the interior.
[0040] In summary, this utility model embodiment provides a piezoelectric sensing rainproof device 100, which includes a rain shelter with an inclined top plate 110. The top plate 110 is inclined downward along its width direction, and a piezoelectric detection unit made of piezoelectric material is provided on the upper surface of the top plate 110. An extension plate 120 is provided at the bottom of the top plate 110. When raindrops fall on the upper surface of the top plate 110, the piezoelectric detection unit is deformed by pressure and transmits a signal to the control module. The control module cuts off the power, causing the first electromagnet 113 to lose its attraction. The extension plate 120 slides down under the action of gravity, forming a larger shielding area, thereby better protecting people or objects under the rain shelter.
[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
