Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aquatic technology, specifically referring to an aquatic environment monitoring and alarm device. Background Technology
[0002] Regularly collecting and analyzing water samples from aquatic environments is a crucial foundation for understanding water quality changes, identifying potential pollution hazards, and developing ecological protection plans. Currently, environmental monitoring of open water bodies such as rivers, lakes, and ponds in the wild mostly adopts a combination of fixed-point sampling and real-time monitoring. However, existing water sampling and monitoring equipment has the following problems:
[0003] (1) Conventional water sampling devices mostly rely on external power to drive them. Whether it is electric water pump pumping for sampling or motor-driven rotary sampling, they all need to be equipped with batteries, external power supply or solar power supply modules, which not only increases the complexity of the overall structure of the equipment, but also greatly increases the equipment cost and the difficulty of later operation and maintenance.
[0004] (2) Existing intermittent sampling equipment generally suffers from excessively fast sampling component rotation speed, which makes it impossible to achieve low-speed and stable intermittent sampling. This can easily lead to water samples from different time periods mixing and cross-contamination. A single sampling container may contain water samples from multiple time periods, which seriously damages the independence and timeliness of the water samples and directly affects the accuracy of subsequent water quality monitoring and analysis data. It cannot truly reflect the actual changes in the water environment at different time periods. Utility Model Content
[0005] This invention overcomes the shortcomings of existing technologies and provides a water environment monitoring and alarm device. It directly converts the horizontal impact force of water flow into the low-speed rotational power of the driven cylinder, achieving completely passive autonomous drive. Through a two-stage deceleration design, the rotational speed of the driven cylinder is greatly reduced, driving the sampling cylinders arranged in a circumferential array to perform low-speed intermittent and precise repositioning. Each sampling cylinder corresponds to independent time period water sample collection, completely eliminating the problem of water sample mixing and cross-contamination at different times, and comprehensively ensuring the independence, timeliness and purity of water samples, improving the accuracy of monitoring data from the source. After all sampling cylinders have completed one circumference of filling and water sample collection is completed, the chute automatically contacts the squeeze button to trigger the alarm light to illuminate and provide a visual prompt.
[0006] The technical solution adopted by this utility model is as follows: This solution provides a water environment monitoring and alarm device, including a float, an airbag, and an alarm light. The airbag is fixedly installed on the upper edge of the circumferential wall of the float to provide sufficient buoyancy for the entire device, ensuring that the device can float stably on the water surface after being deployed into the water area. The alarm light is fixedly installed on the top wall of the float. Water channels are arrayed on the circumferential wall of the float to facilitate the smooth flow of water within the water area. A drive shaft is rotatably connected to the inner top wall of the float. Impeller blades are arrayed on the drive shaft. When water flows over the impeller blades, the impeller blades can be driven by the impact force of the water flow. The impeller blades rotate synchronously with the drive shaft, converting the water flow power into mechanical rotational power, providing driving force for subsequent sampling and alarm actions of the device; a partition is fixedly installed on the inner wall of the float, dividing the inside of the float into two independent cavities, and a water inlet is opened on the partition to realize directional water flow; a driven cylinder is rotatably connected to the bottom wall of the partition, and the driven cylinder is driven in conjunction with the drive shaft. A sampling cylinder is arranged in a circumferential array on the top wall of the driven cylinder to receive the water flow falling from the water inlet and complete the water sample collection. With the rotation of the driven cylinder, intermittent and batch water sample collection is realized, ensuring the orderly collection of water samples.
[0007] Furthermore, the bottom end of the float is fitted with a cover plate to facilitate the subsequent removal of the sampling tube. A reduction gear is rotatably connected to the top wall of the cover plate to transmit rotational force.
[0008] Furthermore, a driven internal gear is fixedly provided on the lower edge of the inner wall of the driven cylinder. The driven internal gear meshes with the reduction gear to drive the driven cylinder to rotate synchronously.
[0009] Furthermore, a transmission gear is fixedly provided on the lower edge of the circumferential wall of the transmission shaft. The transmission gear meshes with the reduction gear and rotates synchronously with the transmission shaft to achieve transmission.
[0010] Furthermore, a groove is provided on the circumferential wall of the driven cylinder, and a button is fixedly provided on the inner wall of the float. The button is nested in the groove and is electrically connected to the alarm light.
[0011] Furthermore, a reset coil spring is fixedly provided on the bottom of the partition plate. The movable end of the reset coil spring is fixedly connected to the inner wall of the driven cylinder to provide reset torque for the driven cylinder. After the device completes the sampling alarm, it can assist the driven cylinder in returning to its initial position.
[0012] Furthermore, a lampshade is fixedly installed on the top wall of the pontoon.
[0013] The beneficial effects of this utility model by adopting the above structure are as follows:
[0014] (1) The horizontal driving force generated by the water flow impacting the impeller blades drives the transmission shaft and transmission gear to rotate. Then, through the two-stage meshing reduction transmission structure of transmission gear, reduction gear and driven internal gear, the high-speed water flow impact force is converted into the low-speed rotation power of the driven cylinder, thus realizing a completely passive autonomous drive.
[0015] (2) The driven internal gear and the reduction gear achieve two-stage reduction, so that the rotation speed of the driven cylinder is much lower than the speed of the transmission shaft, which drives the sampling cylinder of the circumferential array on the top wall of the driven cylinder to rotate at a low speed and intermittently, rather than continuously at high speed. Each rotation is a fixed angle, and a single sampling cylinder moves precisely to the bottom of the inlet of the partition. After being filled once, the next sampling cylinder is switched to avoid the problem of water sample mixing and cross-contamination caused by continuous rapid sampling. The water sample in each sampling cylinder corresponds to the water environment of an independent time period, which fully guarantees the independence, timeliness and purity of the water sample, and provides accurate and reliable samples for subsequent water environment monitoring and analysis.
[0016] (3) During the sampling process of the driven cylinder rotation, the reset coil spring is synchronously charged, the button is nested in the slide groove and is in an untriggered state, and the device smoothly completes the sampling operation one by one; when all the sampling cylinders are filled and the driven cylinder rotates one revolution, the inner wall of the slide groove automatically abuts against the squeezing button, the circuit is instantly triggered and the alarm light is lit to emit a visual alarm signal.
[0017] (4) The button and the slide groove form a mechanical limit, which forcibly locks the driven cylinder, the drive shaft and the impeller blades, preventing them from continuing to rotate, avoiding repeated water intake of the sampling cylinder that could cause water sample to overflow and mix, and achieving automatic self-locking shutdown after sampling to protect the integrity of the water sample.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example 1: Please refer to Figures 1-3 This embodiment provides a water environment monitoring and alarm device, including a float 1, an airbag 2, and an alarm light 3; the airbag 2 is fixedly mounted on the upper edge of the circumferential wall of the float 1, and the alarm light 3 is fixedly mounted on the top wall of the float 1; a cover plate 4 is snapped onto the bottom end of the float 1, and a reduction gear 5 is rotatably connected to the top wall of the cover plate 4; water channels 6 are arrayed on the circumferential wall of the float 1; a drive shaft 7 is rotatably connected to the inner top wall of the float 1, and impeller blades 8 are arrayed on the drive shaft 7; a partition 9 is fixedly mounted on the inner wall of the float 1, and a water inlet 10 is opened on the partition 9; a driven cylinder 11 is rotatably connected to the bottom wall of the partition 9, and a fixed part is mounted on the bottom of the partition 9. A return spring 12 is provided, and the movable end of the return spring 12 is fixedly connected to the inner wall of the driven cylinder 11. Sampling cylinders 13 are arranged in a circular array on the top wall of the driven cylinder 11. A driven internal gear 14 is fixedly provided on the lower edge of the inner wall of the driven cylinder 11. The driven internal gear 14 meshes with the reduction gear 5. A transmission gear 15 is fixedly provided on the lower edge of the circumferential wall of the transmission shaft 7. The transmission gear 15 meshes with the reduction gear 5. A sliding groove 16 is provided on the circumferential wall of the driven cylinder 11. A button 17 is fixedly provided on the inner wall of the float 1. The button 17 is nested in the sliding groove 16 and is electrically connected to the alarm light 3. A lamp cover 18 is fixedly provided on the top wall of the float 1.
[0026] In this embodiment, a long rod is used, and the float 1 is installed at the end of the long rod. The float 1 is then placed in the water. The function of the long rod is to prevent the float 1 from rotating on its own and to position and retrieve the float 1. The airbag 2 provides buoyancy so that the float 1 floats stably on the water surface. The water flow in the water area enters the float 1 through the water channel 6 on the circumferential wall of the float 1. The water flow entering the float 1 enters the sampling tube 13 at the top of the driven tube 11, which is directly opposite the water inlet 10 on the partition 9, and quickly fills the current sampling tube 13, completing a single water sample collection.
[0027] Water flows continuously over the impeller blades 8, and the horizontal impact force of the water flow drives the impeller blades 8 to rotate, which in turn drives the drive shaft 7 and the drive gear 15 to rotate synchronously. The rotation of the drive shaft 7 drives the drive gear 15 to rotate synchronously. The drive gear 15 drives the reduction gear 5 to rotate through meshing. The reduction gear 5 then drives the driven internal gear 14 to rotate slowly through meshing, which in turn drives the entire driven cylinder 11 to rotate around its own axis. After the two-stage reduction transmission of the reduction gear 5 and the driven internal gear 14, the rotation speed of the driven cylinder 11 is much lower than the rotation speed of the drive shaft 7, realizing low-speed and stable intermittent water sample collection. After rotating a certain angle, the next sampling cylinder 13 moves to the position directly below the inlet 10 to complete a new round of water sample filling, avoiding water sample mixing caused by continuous rapid sampling and ensuring the independence and accuracy of the monitored water samples.
[0028] During the rotation of the driven cylinder 11, the return spring 12 on the inner wall gradually accumulates force as it rotates. At the same time, the button 17 on the inner wall of the float 1 is always nested in the groove 16 on the outer wall of the driven cylinder 11 and is in an untriggered state. When the driven cylinder 11 drives all the sampling cylinders 13 to complete one revolution and all water samples are collected, the inner wall of the groove 16 and the button 17 come into contact and are squeezed. The button 17 is triggered and conducts after being squeezed, and the top alarm light 3 is lit instantly through the circuit connection to issue a visual alarm signal. At the same time, the contact between the button 17 and the groove 16 achieves mechanical limitation of the driven cylinder 11, preventing the driven cylinder 11 from continuing to rotate, and simultaneously limiting the rotation of the drive shaft 7 and the impeller blades 8, preventing the sampling cylinders 13 from repeatedly entering water, and completing the entire sampling and alarm process.
[0029] Once the staff observes that the alarm light 3 is lit, they can confirm that the device has completed all water sample collection. The device is then retrieved from the water area. After retrieval, the buckle connection between the bottom of the float 1 and the cover plate 4 is released, the cover plate 4 is removed, and the sampling tubes 13 filled with water samples are taken directly from the top wall of the driven tube 11. Subsequent water environment monitoring and analysis can then be carried out.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
