Description

Technical Field

[0001] This utility model relates to the field of water level monitoring, and in particular to a water level monitoring and marking device for water conservancy engineering surveys. Background Technology

[0002] In water conservancy engineering surveying, water level monitoring is a core component, and the accuracy of its data directly affects engineering design, construction safety, and subsequent operation and maintenance. Traditional water level monitoring and marking devices mainly consist of fixed-scale markers and simple buoys, sometimes combined with basic observation components. These devices are used in water bodies such as rivers, lakes, reservoirs, and irrigation canals to record and mark water level changes, providing surveyors with basic water level data support.

[0003] Traditional devices lack cleaning and interception structures at the water inlet, making it easy for impurities such as silt, weeds, and plankton in the water to clog the water inlet channel. This causes the water level inside the device to rise and fall in sync with the external water level, resulting in lag in the movement of the float or marking components and causing deviations in water level readings. In addition, the scales of traditional devices are mostly directly printed or simply sprayed, making it difficult for surveyors to clearly identify the scales when conducting long-distance observations at night, on cloudy days, or in rainy or foggy conditions. Utility Model Content

[0004] The main purpose of this utility model is to provide a water level monitoring and marking device for water conservancy engineering surveys, which can effectively solve the problems of debris clogging the inlet of traditional devices and difficulty in identification at long distances.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water level monitoring and marking device for water conservancy engineering survey includes a base, a fixing component fixedly connected to the lower part of the base, a connecting seat fixedly connected to the upper part of the base, a water inlet pipe fixedly connected to the side of the connecting seat, a water level monitoring cylinder fixedly connected to the upper part of the connecting seat, and an exhaust structure fixedly connected to the upper part of the water level monitoring cylinder.

[0006] Preferably, a housing is fixedly connected to the end of the water inlet pipe away from the connector, a filter screen is fixedly connected inside the housing, a rotating paddle is rotatably connected to the outer side of the housing and a rubber scraper is fixedly connected to the rotating paddle on the side close to the filter screen.

[0007] Preferably, the exhaust structure includes an exhaust pipe, a guide post is fixedly connected inside the exhaust pipe, the other end of the guide post is fixedly connected to a connecting seat, and an inclined downward ventilation opening is provided on the outside of the exhaust pipe, with a filter screen fixedly connected to the outlet.

[0008] Preferably, the water level monitoring cylinder includes an inner wall, a scale marking ring is fixedly connected to the outer side of the inner wall, and an outer shell is fixedly connected to the inner wall outside the scale marking ring.

[0009] Preferably, the outer shell and inner wall of the monitoring cylinder are made of transparent material, the scale marking ring has three vertical observation grooves on its side, and a scale groove is formed on the side of each observation groove. A reflective film is attached to each scale groove of the scale marking ring.

[0010] Preferably, a sliding sleeve is slidably connected to the outside of the guide post, a float is fixedly connected to the outside of the sliding sleeve, a reflective indicator tube is fixedly connected above the float, a cover is fixedly connected above the float, a sealing ring is fixedly connected between the reflective indicator tube and the cover, and the reflective indicator tube is made of transparent material and has a reflective film and a ring light assembly inside.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a water level monitoring and marking device for water conservancy engineering surveys. The device features a housing at the end of the inlet pipe, with an internal filter screen directly intercepting impurities in the water. Simultaneously, a rotating paddle and rubber scraper, rotatably connected to the outside of the housing, form a self-cleaning structure. As water flows through, the paddle rotates, and the rubber scraper simultaneously removes residual impurities from the surface of the filter screen, preventing clogging. Furthermore, the housing's downward-sloping design allows intercepted impurities to flow out naturally under gravity, ensuring synchronization between the internal and external water levels and improving water level monitoring accuracy.

[0012] 2. This utility model provides a water level monitoring and marking device for water conservancy engineering surveys. The outer shell and inner wall of the water level monitoring cylinder of this utility model are made of transparent material, with no visual obstruction, ensuring that the internal markings can be clearly observed. At the same time, the scale groove of the scale marking ring is affixed with a reflective film, which can enhance light reflection and improve the clarity of long-distance observation. Furthermore, the reflective indicator cylinder above the float is made of transparent material and is equipped with a reflective film and a ring light group inside. After the ring light group is powered on, it can actively supplement the light. The light is diffused by the transparent components and the reflective film. Even in low light environment, surveyors can still accurately read the scale corresponding to the reflective indicator cylinder through remote equipment, achieving stable observation around the clock.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1 As shown, this utility model provides a water level monitoring and marking device for water conservancy engineering surveys, including a base 1, a fixing member 2 fixedly connected to the lower part of the base 1, a connecting seat 3 fixedly connected to the upper part of the base 1, a water inlet pipe 4 fixedly connected to the side of the connecting seat 3, a water level monitoring cylinder 5 fixedly connected to the upper part of the connecting seat 3, and an exhaust structure 6 fixedly connected to the upper part of the water level monitoring cylinder 5. The water inlet pipe 4 fixed to the side of the connecting seat 3 is used to introduce external water; the water level monitoring cylinder 5 fixed to the upper part of the connecting seat 3 serves as the core monitoring area for water level changes; the exhaust structure 6 fixed to the upper part of the water level monitoring cylinder 5 is used to expel air from the device to avoid air resistance affecting water level synchronization.

[0017] like Figure 2 As shown, this utility model provides a water level monitoring and marking device for water conservancy engineering survey. A housing 7 is fixedly connected to the end of the water inlet pipe 4 away from the connecting seat 3. A filter screen 10 is fixedly connected inside the housing 7. A rotating paddle 8 is rotatably connected to the outside of the housing 7 and the rotating paddle 8 is fixedly connected to a rubber scraper 9 on the side near the filter screen 10. The filter screen 10 fixed inside the housing 7 can prevent impurities from entering the water inlet pipe 4 and the water level monitoring cylinder 5 with the water flow. When the external water flows through the housing 7, the impact force of the water flow will drive the rotating paddle 8 to rotate around the axis of the housing 7. The rubber scraper 9 fixed on the side of the rotating paddle 8 near the filter screen 10 will rotate synchronously with the rotating paddle 8 and continuously scrape the outer surface of the filter screen 10.

[0018] like Figure 3As shown, this utility model provides a water level monitoring and marking device for water conservancy engineering survey. The exhaust structure 6 includes an exhaust pipe 61, and a guide column 11 is fixedly connected inside the exhaust pipe 61. The other end of the guide column 11 is fixedly connected to the connecting seat 3. An inclined downward ventilation port is opened on the outside of the exhaust pipe 61, and a filter screen 62 is fixedly connected to the outlet. When external water enters the water level monitoring cylinder 5 and causes the internal water level to rise, the air in the water level monitoring cylinder 5 will be discharged through the ventilation port to avoid air stagnation and air resistance.

[0019] like Figure 4 As shown, this utility model provides a water level monitoring and marking device for water conservancy engineering survey. The water level monitoring cylinder 5 includes an inner wall 52, and a scale marking ring 53 is fixedly connected to the outer side of the inner wall 52. A monitoring cylinder outer shell 51 is fixedly connected to the outer side of the scale marking ring 53. Both the monitoring cylinder outer shell 51 and the monitoring cylinder inner wall 52 are made of transparent material. Three vertical observation grooves are opened on the side of the scale marking ring 53, and a scale groove is opened on the side of each observation groove. A reflective film is attached to each scale groove of the scale marking ring 53. The monitoring cylinder outer shell 51 and the monitoring cylinder inner wall 52 form a double-layer hollow structure. External water enters the monitoring cylinder inner wall 52 through the connecting seat 3.

[0020] like Figure 5 As shown, this utility model provides a water level monitoring and marking device for water conservancy engineering surveys. A sliding sleeve 13 is slidably connected to the outside of a guide column 11, and a float 16 is fixedly connected to the outside of the sliding sleeve 13. A reflective indicator tube 14 is fixedly connected above the float 16, and a cover 12 is fixedly connected above the float 16. A sealing ring 15 is fixedly connected between the reflective indicator tube 14 and the cover 12. The reflective indicator tube 14 is made of transparent material and has a reflective film and a ring light assembly inside. The sliding sleeve 13 is slidably connected to the outside of the guide column 11, and the float 16 fixed to the outside of the sliding sleeve 13 is made of a material with a density less than water. When the water level between the inner wall 52 of the monitoring tube and the outer shell 51 of the monitoring tube rises, the float 16 moves upward under the action of buoyancy, driving... The sliding sleeve 13 slides upward along the guide post 11; when the water level drops, the float 16 moves downward under the action of gravity, and the sliding sleeve 13 slides down along the guide post 11 in sync, realizing real-time synchronization between the float assembly and the water level change. The reflective indicator 14 fixed above the float 16 is made of transparent material and has a reflective film and a ring light assembly inside; the reflective indicator 14 moves synchronously with the float 16, and its position directly corresponds to the scale of the scale marking ring 53, becoming a direct indicator of the water level; the light emitted by the ring light assembly after being powered on is reflected by the transparent reflective indicator 14 and the water level monitoring cylinder 5, and in conjunction with the reflective film in the scale groove of the scale marking ring 53, so that even in low light environments such as at night and in rainy or foggy weather, the scale corresponding to the reflective indicator 14 can be clearly highlighted.

[0021] The working principle of the water level monitoring and marking device for water conservancy project survey will be explained in detail below.

[0022] like Figure 1-5As shown, the entire device is first secured below the water level of the monitored area using the fixing component 2 below the base 1, ensuring that the base 1 and the connecting seat 3 remain vertical, providing a stable reference for subsequent water level monitoring. At this time, the water level monitoring cylinder 5 is partially submerged in water, the exhaust structure 6 is exposed to the air, and the water inlet pipe 4 is connected to the water area, completing the initial deployment. External water flows to the connecting seat 3 through the water inlet pipe 4. Before entering the water inlet pipe 4, it must first pass through the shell 7 at the end of the water inlet pipe 4 away from the connecting seat 3. The filter screen 10 inside the shell 7 intercepts impurities such as silt and plankton in the water, preventing... To prevent impurities from entering the device and clogging the channels, clean water filtered by filter screen 10 flows into connecting seat 3 along water inlet pipe 4, and then into the inner wall 52 of water level monitoring cylinder 5 through connecting seat 3, ensuring that the water level inside the device rises or falls synchronously with the water level in the external water area. Simultaneously, the downward-sloping vent on the outside of the exhaust pipe 61 in the exhaust structure 6 above water level monitoring cylinder 5 expels air from inside the device, preventing air stagnation from causing air resistance and affecting water level synchronization. Furthermore, the filter screen 62 at the vent outlet prevents dust, insects, and other debris from entering the device. A sliding sleeve 13 is slidably connected to the outer side of the guide post 11 inside the inner wall 52. The float 16 fixed outside the sliding sleeve 13 floats synchronously with the water level changes inside the device. When the water level rises, the float 16 moves upward under the action of buoyancy; when the water level drops, the float 16 moves downward under the action of gravity. The reflective indicator 14 fixed above the float 16 moves synchronously with the float 16. At the same time, the sliding sleeve 13 slides along the guide post 11 to ensure that the reflective indicator 14 always moves vertically and avoids tilting or misalignment due to water flow impact. The baffle 12 fixed above the float 16 can prevent water from directly impacting the reflective indicator. The sealing ring 15 between the top of the reflective indicator tube 14 and the cover 12 enhances the sealing performance and prevents water from seeping into the reflective indicator tube 14 and damaging its internal reflective film and ring light assembly. Surveyors can use telescopes or other remote observation equipment to aim at the water level monitoring tube 5. The outer shell 51 and inner wall 52 of the water level monitoring tube 5 are made of transparent material, with no visual obstruction, and the position of the internal reflective indicator tube 14 can be clearly seen. The scale marking ring 53 is fixed on the outside of the outer shell 51 of the monitoring tube, and three vertical observation grooves are opened on the side. The scale grooves on the side of the observation grooves are covered with reflective film.The reflective indicator cylinder 14 is made of transparent material. Its internal ring light group emits light when powered on. The light diffuses through the observation groove of the scale marking ring 53, and the reflective film within the scale groove enhances the light reflection effect. Even in low-light environments such as nighttime, cloudy days, rainy days, and foggy days, surveyors can clearly identify the scale marking ring 53 corresponding to the reflective indicator cylinder 14 via remote equipment, thereby reading real-time water level data. A rotating paddle 8 is rotatably connected to the outer side of the housing 7 of the filter screen 10. When water flows through the housing 7, it drives the rotating paddle 8 to rotate around the housing 7. The rubber scraper 9 fixed to the side of the rotating paddle 8 near the filter screen 10 rotates synchronously, scraping away impurities remaining on the surface of the filter screen 10 to prevent them from adhering and clogging it. Both the housing 7 and the exhaust pipe 61 are designed to slope downwards. Impurities scraped by the rubber scraper 9, some impurities intercepted by the filter screen 10, and airborne debris intercepted by the filter screen 62 will flow naturally out of the device under gravity along the inclined structure, eliminating the need for frequent manual cleaning.
