Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a long-range handheld amphibious obstacle removal and cleaning device for hydrological gauges. Background Technology

[0002] Hydrological gauges are the most basic and core water level observation equipment for hydrological monitoring. Through the clear scale markings on the gauge, water level data can be read intuitively and continuously monitored. The accuracy of the observation data is directly related to the scientificity and reliability of hydrological data compilation, flood early warning and forecasting, water conservancy project scheduling decisions, and rational allocation of water resources. It is a key infrastructure to ensure the safe operation of water conservancy projects, prevent floods and waterlogging disasters, and protect the stability of the water environment.

[0003] Hydrological gauges are mostly deployed outdoors for extended periods, with some constantly submerged in alternating wet and dry environments. During operation, they are highly susceptible to interference from both external environmental factors and water debris, leading to two core types of malfunctions that severely impact water level reading accuracy and can even cause complete failure. Specifically, silt, mud, algae, planktonic slime, and various organic pollutants continuously adhere to the gauge surface. Over time, this layer of dirt thickens, completely obscuring the graduations and numerical markings. This makes it impossible for manual or automated monitoring to clearly identify the scale, resulting in reading errors, misreadings, or even a complete inability to take readings, significantly reducing the accuracy of hydrological monitoring data. Furthermore, drifting branches in waterways often become lodged on the gauges, further obscuring the scale and exacerbating the problem of scale obstruction.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a long-range handheld amphibious obstacle removal and cleaning device for hydrological gauges. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: like Figures 1 to 3 As shown in the figure, a long-range handheld amphibious obstacle clearing and cleaning device for hydrological gauges according to one embodiment of the present invention includes a water pump 1, a battery 2, a third water pipe 3, a cleaning cylinder 4, a disc motor 5, and a control switch 6. The water pump 1 is a small portable DC pump with a rated voltage compatible with the output voltage of the battery 2. The inlet of the water pump 1 is fixedly connected to the first water pipe 11, and the outlet is fixedly connected to the second water pipe 12. The first water pipe 11 is 1.5 meters long and uses a corrosion-resistant PVC flexible hose. A stainless steel filter 13 is installed at the end of the pipe with a mesh size of 0.8 mm, which can effectively filter out large particles of impurities such as silt and aquatic plant debris from the water. This prevents impurities from entering the water pump 1 and causing wear on the pump impeller, extending the continuous service life of the pump, and also prevents the subsequent nozzles 42 from clogging, ensuring smooth water flow and reducing subsequent maintenance costs.

[0022] Battery 2 uses a 12V high-capacity waterproof lithium battery with a single unit weight of less than 8kg. The total weight of the water pump 1 and battery 2 is 26kg. It can be stored in a standard toolbox and can be easily transported to various hydrological monitoring points by a single person without the need for multiple people to cooperate in transportation. It is suitable for the mobile operation needs of scattered field locations.

[0023] The third water pipe 3 is 5 meters long, and its outer surface is treated with a non-slip frosted finish to increase hand grip and facilitate stable force application by the operator. The end of the third water pipe 3 closest to the second water pipe 12 is connected to the second water pipe 12 via a quick connector 7 for a sealed and detachable connection. The quick connector 7 is a snap-on waterproof sealing connector, which eliminates the need for additional wrapping of Teflon tape or sealing tape during the connection operation, achieving a complete seal of the water circuit. The assembly and disassembly time is less than 10 seconds, significantly improving the efficiency of on-site assembly and disassembly.

[0024] A control switch 6 is fixedly installed on the outer wall of the third water pipe 3 near the second water pipe 12. The switch is a waterproof double-push type and is electrically connected to the battery 2, the water pump 1, and the disc motor 5 through waterproof insulated cables. It can realize one-button synchronous start and stop of the water pump 1 and the disc motor 5, or control the start and stop of any component individually. It is flexible and convenient to operate and meets the safety operation requirements of humid water-related environments.

[0025] The cleaning cylinder 4 is a circular hollow sleeve structure with an inner diameter matching the outer diameter of a standard hydrological gauge. An annular water distribution groove 41 is located inside the cylinder, with multiple high-pressure nozzles 42 evenly distributed around its inner wall. These nozzles spray atomized water droplets, ensuring the water flow completely covers the outer circumference of the gauge, eliminating any blind spots in the rinsing of dirt. Two disc motors 5 are symmetrically mounted on the upper and lower sides of the cleaning cylinder 4. These disc motors are waterproof, low-speed, high-torque direct-drive motors, with the rotor extending into the inner cavity of the cleaning cylinder 4. A soft, wear-resistant nylon brush 51 is fixedly connected to the rotor end. The length of the brush 51 is adapted to the cleaning range of the gauge surface, and the bristles have moderate density and hardness. This allows for efficient removal of stubborn deposits such as moss, silt, algae slime, and organic dirt without scratching the gauge's graduation lines or surface paint, ensuring the integrity of the gauge surface. A connecting column 52 is additionally fixedly connected to the rotor of the disc motor 5 located on the lower side of the cleaning drum 4. The connecting column 52 is inclined outward to facilitate the effective dispersal of drifting debris such as branches and weeds stuck on the water gauge during rotation, and to prevent debris from entangled and obstructing the gauge surface.

[0026] During on-site operation, the operator places the water pump 1 and battery 2 stably on a flat, dry spot on the bank of the water gauge. The first water pipe 11 is inserted below the water surface of the monitored area. The second water pipe 12 and the third water pipe 3 are quickly and sealed together using the quick connector 7. Then, holding the end of the third water pipe 3, the cleaning cylinder 4 is smoothly fitted onto the outside of the water gauge to be cleaned. The control switch 6 is pressed to start the entire system. At this time, the battery 2 simultaneously powers the water pump 1 and the disc motor 5. The water pump 1 draws water from the area, which is filtered by the filter 13 to remove impurities. The water then flows sequentially through the second water pipe 12 and the third water pipe 3 to the annular water distribution trough 41 of the cleaning cylinder 4. Multiple high-pressure nozzles 42 simultaneously spray high-pressure water onto the surface of the water gauge. The disc motor 5 operates synchronously, driving the nylon brush 51 to rotate at a uniform speed, forming a dual combination of high-pressure water rinsing and gentle brushing by the mechanical brush 51, quickly removing various stubborn dirt from the gauge surface. During the cleaning process, the operator holds the third water pipe 3 and slowly moves it up and down along the water gauge, controlling the movement speed at approximately 0.2 m / s to achieve all-around cleaning of the entire surface of the water gauge. Simultaneously, the lower disc motor 5 drives the arc-shaped connecting column 52 to rotate synchronously, continuously dislodging and pushing debris such as branches and weeds stuck on the water gauge. This debris is then rotated and pushed downstream, where the natural water flow washes it away. Combined with the localized high-pressure water jet from the nozzle 42, this further accelerates the removal of debris from the water gauge, completely resolving the problem of drifting debris obscuring the scale. After the cleaning operation is completed, the control switch 6 is turned off to disconnect the power, the quick connector 7 is disconnected to separate the water circuit, and all components are wiped dry and stored in the toolbox before being transported to the next monitoring point for further work.

[0027] Example 2: like Figures 1 to 4As shown, the third water pipe 3 abandons the one-piece structure and adopts a multi-segment splicing portable structure. Specifically, it includes multiple first pair connectors 31, each 1.2 meters long. Adjacent first pair connectors 31 are connected by threads to a second pair connector 32. The inner wall of the second pair connector 32 is embedded with a waterproof rubber sealing ring. After splicing, the overall sealing performance is excellent and there is no leakage. The total length of the third water pipe 3 after splicing is 6 meters, which fully meets the needs of long-distance operation. After the operation is completed, the third water pipe 3 can be quickly disassembled and stored directly in the trunk of an ordinary vehicle without occupying a large storage space. This completely solves the problems of inconvenient transportation, easy bending and damage, and difficult storage of one-piece long pipes.

[0028] The third pair of connecting pipes 45 is welded and fixed at the connection end of the cleaning cylinder 4 and the third water pipe 3. The third pair of connecting pipes 45 is threaded and can be detachably connected to the threaded end of the third water pipe 3. The cleaning cylinder 4 with the corresponding inner diameter can be quickly replaced according to the actual outer diameter of the hydrological gauge on site, without replacing the entire device, which greatly improves the versatility of the device and can be adapted to various diameter standard hydrological gauges.

[0029] Furthermore, the water pump 1 is still equipped with a filter 13, which can be a filter cartridge with multiple layers of filter screens. It can effectively filter impurities such as silt, suspended solids, and algae in the river water. This not only prevents impurities from entering the pump body, wearing the impeller and seals, and extending the service life of the water pump 1, but more importantly, it can effectively prevent impurities from clogging the third water pipe 3 and the nozzle 42 on the cleaning cylinder 4, ensuring the long-term stable operation of the cleaning system.

[0030] The overall usage process of the device in this embodiment is basically the same as that in Embodiment 1. The splicing design can also flexibly increase or decrease the number of the first pair of pipes 31 according to the actual operating distance, and adjust the total length of the third water pipe 3 in real time to adapt to water gauge points at different distances and water levels, making the operation extremely flexible.

[0031] Example 3: like Figures 1 to 3 As shown, this embodiment improves the stability of the device during operation based on the technology of Embodiment 1 and Embodiment 2, avoids shaking and displacement of the cleaning cylinder 4, ensures that the spray distance of each nozzle 42 is uniform and consistent, and the brush 51 has a moderate and balanced brushing force, thereby further enhancing the cleaning effect.

[0032] Specifically, two sets of annular air grooves 43 are symmetrically formed on the upper and lower sides of the annular water distribution groove 41 within the inner cavity of the cleaning cylinder 4. The openings of both sets of air grooves 43 are sealed and fixedly connected to elastic bladders 44. The elastic bladders 44 are made of corrosion-resistant, water-pressure-resistant, and highly elastic silicone material, offering strong sealing and excellent elastic recovery performance, preventing scratches or damage when fitting against the surface of the water gauge. Two independent air valves 46 are fixedly installed on the outer wall of the cleaning cylinder 4, each corresponding to and sealingly connected to one of the two sets of air grooves 43. Compressed air can be easily injected into or discharged from the air grooves 43 using a small manual or electric air pump.

[0033] Before the formal operation, according to the actual outer diameter of the hydrological gauge to be cleaned, an appropriate amount of compressed air is injected into the air groove 43 through the air valve 46, causing the elastic bladder 44 to expand slowly and evenly until the inner wall of the elastic bladder 44 slightly adheres to the surface of the gauge and the inner diameter is slightly larger than the outer diameter of the gauge, forming a flexible self-adaptive limiting structure. During the cleaning operation, this flexible limiting structure can effectively limit the radial sway and axial displacement of the cleaning cylinder 4, ensuring that the spray distance between the multiple uniformly distributed nozzles 42 and the surface of the gauge is consistent, avoiding problems such as incomplete cleaning in some areas and damage to the gauge surface due to uneven distance; at the same time, the stable limiting effect can ensure that the brush 51 adheres evenly to the surface of the gauge, ensuring that stubborn dirt is thoroughly removed, and comprehensively improving the cleaning accuracy and cleanliness. The structure of two sets of air tanks 43 arranged symmetrically above and below further improves the coaxiality of the cleaning cylinder 4 and the water gauge. When the operator moves the third water pipe 3 up and down for cleaning, there will be no jamming, deviation or tilting. It is especially suitable for water gauge cleaning operations in areas with alternating dry and wet conditions and thick layers of dirt.

[0034] After the operation is completed, the air inside the elastic bladder 44 is discharged through the air valve 46, and the elastic bladder 44 can then contract and reset, without affecting the storage and transportation of the device. It can be refilled and used repeatedly, with a long overall service life and low maintenance costs.

[0035] Compared with existing technologies, the long-distance handheld amphibious obstacle removal and cleaning device for hydrological gauges of the present invention has the advantages of being portable and easy to transport, simple to operate, amphibious, and capable of cleaning and obstacle removal simultaneously. It completely solves the problems of reading errors and monitoring failures caused by dirt and debris blockage on traditional hydrological gauges, ensuring the accurate and efficient conduct of hydrological monitoring work.
