Description

Technical Field

[0001] This utility model relates to the technical field of flood warning devices, specifically a flood warning device with an adjustable rainfall threshold. Background Technology

[0002] Currently, in the fields of flood control, disaster reduction, and hydrological monitoring, various water level early warning devices are widely used in areas such as rivers, reservoirs, low-lying urban roads, and underground parking lots. Traditional water level monitoring equipment usually uses fixed water level sensors to sense water level changes in real time and issue alarm signals when the water level reaches a preset height. Some devices also integrate photovoltaic power supply modules to support long-term unattended outdoor operation. These devices provide technical support for flood control early warning to a certain extent and help reduce the risk of flood disasters caused by sudden rises in water levels.

[0003] Traditional sensors are installed at a fixed height, making it difficult to adjust them flexibly according to different terrains. This can easily lead to missed or false alarms in areas where the depth of the river varies. Utility Model Content

[0004] The purpose of this invention is to provide a flood warning device with an adjustable rainfall threshold, which solves the problem that the sensor installation height of traditional devices is fixed and it is difficult to adjust flexibly according to different terrains, resulting in missed or false alarms in areas with varying river depths.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a flood warning device with an adjustable rainfall threshold, comprising a controller, a fixed rod mounted on the outer surface of the controller, a scale line on the outer surface of the fixed rod, a base fixedly mounted on the lower surface of the fixed rod, a photovoltaic panel mounted on the top of the fixed rod, a connecting plate fixedly mounted on the outer surface of one end of the fixed rod, an alarm light mounted on the upper surface of the connecting plate, sliding grooves on both sides of the fixed rod, an observation mechanism for easy observation of the scale line on the outer surface of the fixed rod, and an adjustable detection mechanism for adjustable height mounted on the lower surface of the controller.

[0007] Furthermore, the observation mechanism includes a sliding sleeve that is fitted onto the outer surface of the fixed rod and slidably connected to the inside of the sliding groove. Mounting plates are fixedly installed on both sides of the sliding sleeve, and mounting rings are fixedly installed on one end of each mounting plate. Floats are installed inside each mounting ring. A pointer head is fixedly installed on the outer surface of one of the mounting plates, and the pointer head corresponds to the position of the scale line.

[0008] Furthermore, the adjustable detection mechanism includes a fixed cylinder, which is fixedly installed on the lower surface of the controller. A motor is installed on the inner top of the fixed cylinder, a limit rod is fixedly installed inside the fixed cylinder, a lead screw is fixedly installed at the output end of the motor, and a movable plate is threadedly connected to the outer surface of the lead screw.

[0009] Furthermore, the interior of the movable plate and the outer surface of the limiting rod are slidably connected.

[0010] Furthermore, a positioning plate is fixedly installed on the outer surface of the movable plate.

[0011] Furthermore, a water level sensor is fixedly installed on the lower surface of the positioning plate.

[0012] This utility model has the following beneficial effects:

[0013] (1) By setting an adjustable detection mechanism, this utility model can accurately control the lifting position of the water level sensor by using the screw drive of the motor and the thread transmission of the movable plate. According to the actual needs of different installation areas, the initial detection height of the sensor can be flexibly adjusted. This not only improves the adaptability of the device to different terrains, but also avoids false alarms or missed alarms caused by unreasonable fixed installation height. It realizes the precise adjustment of the rainfall threshold and improves the reliability and flexibility of flood warning.

[0014] (2) By setting up an observation mechanism, the float moves synchronously along the scale line with the natural rise and fall of the water level, allowing on-site personnel to intuitively read the current actual water level. The water level can be quickly confirmed through manual observation, which is convenient for daily inspection, maintenance and calibration, as well as manual verification in emergency situations. This effectively enhances the system's fault tolerance and the convenience of on-site operation.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a flood warning device with an adjustable rainfall threshold, including a controller 1, a fixed rod 2 installed on the outer surface of the controller 1, a scale line 201 opened on the outer surface of the fixed rod 2, a base 3 fixedly installed on the lower surface of the fixed rod 2, a photovoltaic panel 5 installed on the top of the fixed rod 2, a connecting plate 6 fixedly installed on the outer surface of one end of the fixed rod 2, an alarm light 7 installed on the upper surface of the connecting plate 6, a sliding groove 4 opened on both sides of the fixed rod 2, an observation mechanism 8 for easy observation of the scale line 201 on the outer surface of the fixed rod 2, and an adjustable detection mechanism 9 with adjustable height installed on the lower surface of the controller 1;

[0025] Specifically, when the controller 1 determines that the warning conditions have been met, it immediately drives the alarm light 7 to emit a flashing or constant light signal to issue a warning. At the same time, the device can use the photovoltaic panel 5 to convert solar energy into electrical energy to power the controller 1, motor 902, water level sensor 907, and alarm light 7, ensuring that the device can work continuously outdoors without human intervention for a long period of time. In summary, the adjustable detection mechanism 9 flexibly sets the detection depth, and combined with the observation mechanism 8, it realizes on-site water level visualization verification. The controller 1 compares the preset threshold with the real-time water level signal, and finally controls the alarm light 7 to realize on-demand warning, thereby achieving the flood warning function with adjustable rainfall threshold.

[0026] The observation mechanism 8 includes a sliding sleeve 801, which is sleeved on the outer surface of the fixed rod 2 and slidably connected to the inside of the sliding groove 4. Mounting plates 802 are fixedly installed on both sides of the sliding sleeve 801, and mounting rings 803 are fixedly installed on one end of each mounting plate 802. Floats 804 are installed inside each mounting ring 803. A pointer head 805 is fixedly installed on the outer surface of one of the mounting plates 802, and the pointer head 805 corresponds to the position of the scale line 201.

[0027] Specifically, the observation mechanism 8 is used for auxiliary verification and on-site intuitive monitoring. The float 804 gains buoyancy as the water level rises, which drives the sliding sleeve 801 to slide upward along the groove 4 on the surface of the fixed rod 2. The pointer head 805 on one side of the sliding sleeve 801 will move synchronously and point to the scale line 201 on the fixed rod 2. On-site personnel can intuitively read the current water level height by the corresponding position of the pointer head 805 and the scale line 201.

[0028] The adjustable detection mechanism 9 includes a fixed cylinder 901, which is fixedly installed on the lower surface of the controller 1. A motor 902 is installed on the inner top of the fixed cylinder 901. A limit rod 903 is fixedly installed inside the fixed cylinder 901. A lead screw 904 is fixedly installed at the output end of the motor 902. A movable plate 905 is threadedly connected to the outer surface of the lead screw 904.

[0029] The inner surface of the movable plate 905 and the outer surface of the limiting rod 903 are slidably connected;

[0030] A positioning plate 906 is fixedly installed on the outer surface of the movable plate 905;

[0031] A water level sensor 907 is fixedly installed on the lower surface of the positioning plate 906;

[0032] Specifically, the motor 902 drives the lead screw 904 to rotate. Since the movable plate 905 is threadedly connected to the lead screw 904 and its rotation is restricted by the limit rod 903, the rotation of the lead screw 904 is converted into the linear lifting and lowering motion of the movable plate 905. The movable plate 905 drives the water level sensor 907 to rise and fall synchronously through the positioning plate 906, thereby accurately adjusting the initial detection height of the water level sensor 907 from the water surface according to the actual installation environment or historical water level data. When the water level rises and touches and exceeds the probe of the water level sensor 907, the water level sensor 907 immediately sends a water level signal to the controller 1.

[0033] Working Principle: When this utility model is in operation, the device is first fixedly installed in the area where the water level needs to be monitored via the base 3. After the device is powered on, the motor 902 in the adjustable detection mechanism 9 begins to work. The specific working process of the adjustable detection mechanism 9 is as follows: the motor 902 drives the lead screw 904 to rotate. Since the movable plate 905 is threadedly connected to the lead screw 904 and its rotation is restricted by the limiting rod 903, the rotation of the lead screw 904 is converted into the linear lifting and lowering motion of the movable plate 905. The movable plate 905 drives the water level sensor 907 to rise and fall synchronously via the positioning plate 906, thereby accurately adjusting the initial detection height of the water level sensor 907 from the water surface according to the actual installation environment or historical water level data. When the water level rises and contacts and exceeds the probe of the water level sensor 907, the water level sensor 907 immediately sends a water level signal to the controller 1. At the same time, the observation mechanism 8 is used for auxiliary verification and on-site visual monitoring. The float 804 gains buoyancy as the water surface rises, driving the sliding sleeve 801 along the groove 4 on the surface of the fixed rod 2. Sliding upwards, the pointer 805 on one side of the sliding sleeve 801 moves synchronously and points to the scale line 201 on the fixed rod 2. On-site personnel can intuitively read the current water level by observing the corresponding position of the pointer 805 and the scale line 201. The controller 1 has preset rainfall and water level trigger thresholds. When the water level signal detected by the water level sensor 907 exceeds the preset threshold, the controller 1 determines that the warning condition has been met and immediately drives the alarm light 7 to emit a flashing or constant light signal for warning. At the same time, the device can use the photovoltaic panel 5 to convert solar energy into electrical energy to power the controller 1, motor 902, water level sensor 907, and alarm light 7, ensuring that the device can work continuously outdoors without human intervention for a long time. In summary, the adjustable detection mechanism 9 flexibly sets the detection depth and, combined with the observation mechanism 8, realizes on-site water level visualization verification. The controller 1 compares the preset threshold with the real-time water level signal and finally controls the alarm light 7 to realize on-demand warning, thereby achieving the flood warning function with adjustable rainfall threshold.
