[0040] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.
[0041] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0042] This utility model embodiment provides a floating water leakage early warning device, such as Figures 1 to 4 As shown, the device includes a housing 1, and an electric field sensing module, a signal processing module, an alarm module, and a battery module disposed within the housing 1.
[0043] The housing 1 is a sealed and waterproof housing. It can be made of engineering plastics, silicone sealing layer, etc., and has a waterproof rating of IP68.
[0044] The electric field sensing module is located inside the sealed cavity of the housing 1 and is used to sense and detect the electric field in the water.
[0045] The signal processing module is also located inside the sealed cavity of the housing 1, and is electrically connected to the electric field sensing module to receive the detection signal from the electric field sensing module and perform signal processing.
[0046] The alarm module is located inside the sealed cavity of housing 1 and is electrically connected to the signal processing module. It controls the alarm module to provide early warning based on the signal processed by the signal processing module.
[0047] The battery module is located in the sealed cavity of the housing 1 and is electrically connected to the electric field sensing module, signal processing module, alarm module, etc., to provide power for the entire early warning device.
[0048] The battery module is preferably a rechargeable battery module, more preferably a rechargeable lithium battery, and supports wireless charging. It can be reused multiple times and eliminates the need for a charging port, reducing the risk of water ingress.
[0049] The housing 1 of this early warning device, after being equipped with an electric field sensing module, a signal processing module, an alarm module, and a battery module, allows it to float on water. That is, the overall density of the early warning device is slightly less than the density of water, enabling it to float on the water surface for electric field detection during use.
[0050] Lightweight waterproof materials (such as polyurethane foam) can be filled inside the housing 1, especially in the sealed cavity, to ensure stable installation of each module component and fixation of the installation position, effectively ensuring that the early warning device floats and has a stable center of gravity.
[0051] In one embodiment, the early warning device further includes a GPS / BeiDou positioning module, which is disposed within a sealed cavity of the housing 1 and electrically connected to the battery module. It can record the coordinates of the leaking water body / area in real time.
[0052] In one embodiment, the warning device is further provided with a counterweight (not shown in the figure). The counterweight is fixedly installed on one side inside the housing 1, so that when the warning device / housing 1 is in the water, the side of the counterweight always faces downward. That is, when in use, the posture of the warning device / housing 1 in the water is basically the same (vertical state) and will not change due to the throwing direction, angle, etc.
[0053] Furthermore, in one implementation, such as Figures 1 to 4As shown, the housing 1 includes a main body 11 with a larger volume at one end and a counterweight 12 with a smaller volume at the other end. The counterweight 12 extends outward from the center of one side (i.e., the lower side) of the main body 11. A counterweight block is disposed within the counterweight 12. The counterweight 12 protrudes from one side of the main body 11, causing the center of gravity of the warning device / housing 1 to extend downward into the water when it is in the water, thus improving stability.
[0054] The electric field sensing module, signal processing module, alarm module, battery module, and GPS / BeiDou positioning module are all housed within the main body 11. The electric field sensing module is positioned close to or with its sensing end facing the counterweight 12. This ensures that when the warning device is in use, the sensing end of the electric field sensing module is always facing downwards and close to the water surface, guaranteeing accurate detection of the electric field in the water.
[0055] In one embodiment, the alarm module includes an alarm driving circuit, a high-brightness LED strobe light 31 connected to the alarm driving circuit, and a buzzer 32. The alarm driving circuit can be a transistor (such as a 2N2222). The high-brightness LED strobe light 31 includes at least two color flashing modes. That is, the alarm module provides early warning through a combination of sound and light. The high-brightness LED strobe light 31 can include two flashing modes: green and red, or three flashing modes: green, yellow, and red. This allows for early warning of different situations, such as no leakage or leakage in the water, facilitating quick identification by the user.
[0056] Furthermore, a transparent cover 2 is provided on the other side of the main body 11, that is, the upper side or the side away from the counterweight 12. The high-brightness LED strobe light 31 and the buzzer 32 of the alarm module extend out of the main body 12 and are located within the area covered by the transparent cover 2. The transparent cover 2 is provided with several sound outlet holes 21. The transparent cover 2 protects the high-brightness LED strobe light 31 and the buzzer 32 and ensures that the light and sound are transmitted.
[0057] In one embodiment, the main body 11 is configured with a circular or polygonal projection, such as a quasi-cylindrical, quasi-spherical, oblate, or polygonal prism shape. The counterweight 12 is configured with a cylindrical structure, with one end of the counterweight 12 away from the main body 11 being a pointed or rounded end; the connection between the main body 11 and the counterweight 12 has a tapered transition, and the main body 11 and the counterweight 12 are coaxially arranged. This makes the structure of the warning device more reasonable, facilitates throwing, and ensures a stable center of gravity.
[0058] Preferably, the electric field sensing module is a capacitive or electric field strength sensor, such as the CM-01 capacitive sensor, which can detect AC electric fields with a frequency of 50Hz to 1kHz.
[0059] In one embodiment, the signal processing module includes an amplifier circuit, a filter circuit, and a comparator (voltage comparator), which is connected to the alarm drive circuit of the alarm module. The amplifier circuit, filter circuit, and comparator are connected sequentially. The signal processing module receives the detection signal from the electric field sensing module, amplifies and filters it, and then performs a threshold comparison using the comparator. Based on the comparison result, it controls the alarm drive circuit to drive a high-brightness LED strobe light 31 and a buzzer 32 to provide a warning (e.g., when the electric field strength is ≥5V / m, the high-brightness LED strobe light flashes red and the buzzer sounds). The threshold parameter (e.g., voltage) in the comparator can be modified using a potentiometer to adapt to different detection requirements.
[0060] In one embodiment, the warning device is further equipped with a traction rope (not shown in the figure), which is detachably connected to the housing 1 and is made of insulating material. This traction rope allows for the relocation and retrieval of the warning device during throwing, effectively preventing its loss.
[0061] This invention relates to a floating water leakage early warning device that can automatically float on the water surface after being thrown, detect leakage in the water body in the area, and provide audible and visual alarms based on the detection results. It can prevent people from approaching the water body with leakage, realize remote deployment, automatically detect water leakage and provide early warning, is convenient and safe to use, and has a large detection range.
