Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring equipment, in particular to a water level monitoring structure for a hydraulic project. Background Art

[0002] Water conservancy projects refer to flood control, waterlogging removal, irrigation, power generation, water supply, reclamation, soil and water conservation, immigration, water resource protection and other projects and their supporting and ancillary projects. They are used to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's life and production for water resources. Among them, water level monitoring is an indispensable part of water conservancy project monitoring work. It is an important indicator reflecting the changes in water bodies and water flows. Water level observation can be directly used for hydrological information forecasting, and timely provide water information for flood control and drought relief, irrigation, shipping and the construction, use and management of water conservancy projects. The water level data accumulated over a long period of time is the basic basis for the construction planning and design of water conservancy and hydropower, bridges, waterways, ports, urban water supply and drainage, etc. Therefore, it is often necessary to use monitoring devices to observe the changes in water levels in real time.

[0003] At present, water level monitoring mostly adopts methods such as setting up benchmarks or marking water level warning lines on the inclined wall of the dam body. It is impossible to monitor the water level changes in real time, and it is also impossible to accurately read the height of the water level changes. There are many limitations. The height of the traditional monitoring device is fixed, and it cannot be adjusted according to the actual monitored water depth. It is not practical. At the same time, there is no embedded cone at the bottom of the device, so the device cannot be stably placed on the bottom of the water, and the effective monitoring of the device will be affected by the flow of water, wind and waves;

[0004] The existing patent (Announcement No.: CN215338503U) discloses a water level monitoring device for water conservancy projects. This utility model discloses a water level monitoring device for water conservancy projects, including a monitoring structure, a lifting rod and a bottom plate. The beneficial effects of this utility model are: the supporting frame, the sliding rod, the lifting inner rod, the lifting outer rod, the bottom plate and the embedded cone are all made of stainless steel materials to prevent the device from rusting in the water for a long time and extend its service life. The floating rod is slidably connected to the inner side of the supporting frame through the sliding sleeve and the sliding rod, and can reflect the water level change according to the up and down floating of the floating rod, so as to realize real-time monitoring of the water level of the water body. The scale lines are evenly distributed on the ruler, which is convenient for personnel to accurately read the water level height. The lifting inner rod and the lifting outer rod are telescopically connected by fastening bolts, which is convenient for adjusting the height of the monitoring structure, and then the water level of water bodies at different depths can be monitored, thereby improving the practicality of the device. There are multiple embedded cones evenly distributed on the bottom surface of the bottom plate, so that the device can be stably placed on the bottom of the water to avoid the influence of flowing water and wind and waves.

[0005] In view of the above problems, existing patents have provided solutions. However, the embedded cone proposed in the above patents is vertically inserted into the bottom of the water, which can provide a certain stability during the initial installation. However, it is subjected to the continuous impact of flowing water for a long time. According to the principle of mechanics, the impact force of the water flow will produce a lateral component force on the embedded cone. Even if the embedded cone has a certain insertion resistance in the vertical direction, if the lateral component force continues to act without other effective resistance measures, it is possible to cause the embedded cone to gradually shift. Once the embedded cone shifts, the basic stability of the entire device will be destroyed, which will further affect the placement of the device as a whole on the bottom of the water, causing the device to shake, tilt, etc. during the process of monitoring the water level, affecting the accuracy and stability of the monitoring. At the same time, due to the water body in the water conservancy project It usually contains various debris and garbage, such as branches, leaves, plastic garbage, etc. When there is no protective structure on the outside of the supporting frame, these debris and garbage can easily float into the supporting frame with the water flow. The sliding sleeve, floating rod and floating ball are key components for realizing water level monitoring. The entry of debris and garbage may be entangled in the sliding sleeve, increasing the friction between the sliding sleeve and the sliding rod, and hindering the smooth sliding of the floating rod. It may also adhere to the surface of the floating ball, changing the buoyancy characteristics of the floating ball, affecting the up and down floating of the floating rod, and may even directly jam the floating rod, making it unable to move normally with the water level changes. These situations will cause the lifting and lowering of the ruler to be unstable, and thus unable to accurately reflect the water level changes, seriously affecting the monitoring effect and service life of the device, and is not conducive to the actual water level monitoring work of water conservancy projects.

[0006] Therefore, a water level monitoring structure for water conservancy projects is proposed. Utility Model Content

[0007] The purpose of the present utility model is to provide a water level monitoring structure for water conservancy projects, which can solve the problems proposed in the above patent. The embedded cone is vertically inserted into the bottom of the water. It can provide a certain stability during the initial installation. However, when continuously impacted by flowing water for a long time, according to the principle of mechanics, the impact force of the water flow will generate a lateral component force on the embedded cone. Even if the embedded cone has a certain insertion resistance in the vertical direction, if the lateral component force acts continuously and there are no other effective resistance measures, it may cause the embedded cone to gradually shift. Once the embedded cone shifts, the basic stability of the entire device will be damaged, thereby affecting the overall installation state of the device at the bottom of the water, causing the device to shake, tilt, etc. during the water level monitoring process, affecting the accuracy and stability of the monitoring. At the same time, because the water body in water conservancy projects usually contains various sundries and garbage, such as branches, leaves, plastic garbage, etc., when there is no protective structure outside the support frame, these sundries and garbage are easily floated into the inside of the support frame along with the water flow. The sliding sleeve, floating rod and floating ball are the key components for realizing water level monitoring. The entry of sundries and garbage may be wound around the sliding sleeve, increasing the friction between the sliding sleeve and the sliding rod, hindering the smooth sliding of the floating rod, or may adhere to the surface of the floating ball, changing the buoyancy characteristics of the floating ball, affecting the up and down floating of the floating rod, or even directly jamming the floating rod, making it unable to move normally following the change of the water level. These situations will all lead to the unstable lifting of the scale rod, and thus unable to accurately reflect the change of the water level, seriously affecting the monitoring effect and service life of the device, and being unfavorable to the actual water level monitoring work of water conservancy projects.

[0008] To achieve the above object, the present utility model provides the following technical solution: A water level monitoring structure for water conservancy projects, including a bottom plate, a fixed embedding component is arranged at the bottom of the bottom plate, a lifting adjusting rod is fixedly connected to the top of the bottom plate, a frame is bolted to the top of the lifting adjusting rod, protective components are arranged on the front side and the rear side of the frame, sliding rods are fixedly connected to both sides inside the frame, a slider is slidably connected to the surface of the sliding rod, an auxiliary sliding structure is arranged outside the slider, a floating plate is fixedly connected to the inside of the slider, a floating ball is arranged at the bottom of the floating plate, a chute is opened at the top of the frame, a scale rod is bolted to the top of the floating plate, and the scale rod is slidably connected inside the chute;

[0009] The fixed embedding component includes a positioning cone fixedly connected to the inside of the bottom plate, an inclined hole is opened on the outside of the positioning cone, a lateral support positioning rod is arranged inside the inclined hole, a pushing cone rod is arranged inside the positioning cone, and the bottom of the pushing cone rod is located inside the lateral support positioning rod.

[0010] Preferably, the protective component includes positioning holes opened on the front side and the rear side of the frame, and magnetic absorption sheets are embedded at the top and the bottom of the front side and the rear side of the frame.

[0011] Preferably, protective nets are arranged on both the front side and the rear side of the frame. Positioning columns are fixedly connected to both the top and the bottom inside the protective net, and the positioning columns are clamped inside the positioning holes.

[0012] Preferably, magnet sheets are embedded in both the top and the bottom inside the protective net, and the magnet sheets are magnetically connected to the magnetic attraction sheets.

[0013] Preferably, a turntable is fixedly connected to the top of the push cone rod, and a connecting threaded sleeve is fixedly connected to the outer side of the bottom of the turntable.

[0014] Preferably, a threaded ring hole is formed in the top of the positioning cone, and the threaded ring hole is located at the bottom of the connecting threaded sleeve.

[0015] Preferably, the auxiliary sliding structure includes a frame box bolted to the outside of the slider, and fixed rods are fixedly connected to both the front side and the rear side inside the frame box.

[0016] Preferably, an auxiliary shaft is rotatably connected to the inner side of the fixed rod, and the surface of the auxiliary shaft contacts the inner wall of the inside of the frame.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. In this application, by setting the fixed burial assembly, when the device is placed at the bottom of the water for installation, first insert the positioning cone into the bottom of the water. The positioning cone is the main insertion component, and its sharp shape is convenient for penetrating media such as soil at the bottom of the water, providing a preliminary fixed foundation for the device. Then, push down the push cone rod. While it moves downward, the outer side of its bottom exerts a squeezing effect on the lateral support positioning rod. Under the thrust of the push cone rod, the lateral support positioning rod extends out from the inclined hole outside the positioning cone. After the lateral support positioning rod extends out, it forms a certain angle with the positioning cone and inserts into the soil around the bottom of the water, thereby increasing the contact area and friction force with the bottom medium. This multi-directional support structure can effectively resist the lateral impact force of the water flow. When the water flow generates a lateral component force on the positioning cone, the lateral support positioning rod can provide additional resistance to prevent the positioning cone from shifting;

[0019] 2. In this application, by setting the protection component, when the water flow carries debris and garbage towards the device, the protection component plays an interception role, greatly reducing the amount of debris and garbage entering the inside of the frame. In this way, it can avoid the debris and garbage from winding around the slider of the sliding rod, reducing the friction force between the slider and the sliding rod, ensuring that the slider can slide smoothly on the sliding rod. At the same time, it also prevents the debris from adhering to the surface of the floating ball and changing the buoyancy characteristics of the floating ball, as well as avoiding the debris directly jamming the floating rod, ensuring that the floating rod can normally float up and down with the change of the water level. Furthermore, the floating plate can stably drive the scale rod to slide in the chute at the top of the frame, accurately reflecting the change of the water level, and improving the accuracy and stability of water level monitoring.

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-6 , the present utility model provides the following technical solutions:

[0029] A water level monitoring structure for a water conservancy project, including a bottom plate 1, a fixed burial component 2 is arranged at the bottom of the bottom plate 1, a lifting and adjusting rod 3 is fixedly connected to the top of the bottom plate 1, a frame 4 is bolted to the top of the lifting and adjusting rod 3, protection components 5 are arranged on the front side and the rear side of the frame 4, sliding rods 6 are fixedly connected to both sides inside the frame 4, sliders 7 are slidably connected to the surfaces of the sliding rods 6, auxiliary sliding structures 8 are arranged on the outer sides of the sliders 7, floating plates 9 are fixedly connected to the inner sides of the sliders 7, floating balls 10 are arranged at the bottoms of the floating plates 9, a chute 11 is opened at the top of the frame 4, a scale rod 12 is bolted to the top of the floating plate 9, and the scale rod 12 is slidably connected inside the chute 11;

[0030] The fixed burial component 2 includes a positioning cone 201 fixedly connected to the inside of the bottom plate 1, an inclined hole 202 is opened on the outer side of the positioning cone 201, a lateral support positioning rod 203 is arranged inside the inclined hole 202, a pushing cone rod 204 is arranged inside the positioning cone 201, and the bottom of the pushing cone rod 204 is located inside the lateral support positioning rod 203.

[0031] In this embodiment: By setting the fixed burial component 2, the positioning cone 201 is inserted into the bottom of the water to provide preliminary fixation. During the insertion of the positioning cone 201, the pushing cone rod 204 rises under the reaction force of the bottom of the water, and pushes the lateral support positioning rod 203 to extend from the inclined hole 202 and insert into the surrounding soil at the bottom of the water, increasing the contact area and friction with the bottom of the water. The multi-directional support effectively resists the lateral impact force of the water flow, preventing the positioning cone 201 from shifting, thereby greatly improving the stability of the device at the bottom of the water, ensuring that the device can still be stably placed under long-term water flow impact, and providing a solid foundation for accurately monitoring the water level. By setting the protection components 5, a protection barrier is formed on the front side and the rear side of the frame 4, effectively intercepting the sundries and garbage carried in the water flow, preventing them from entering the inside of the frame 4 and winding around the slider 7, affecting the buoyancy of the floating ball 10 or jamming the floating rod. At the same time, the auxiliary sliding structure 8 further ensures the smooth sliding of the slider 7 on the sliding rod 6, ensuring that the floating plate 9 can normally drive the scale rod 12 to slide in the chute 11 with the change of the water level, thereby realizing the accurate monitoring of the water level change, improving the accuracy and stability of the water level monitoring, extending the service life of the device, and making it more adaptable to the complex water environment of the water conservancy project.

[0032] Specifically, as Figure 3 shown, the protection component 5 includes positioning holes 501 opened on the front side and the rear side of the frame 4, and magnetic attraction sheets 502 are embedded at the top and the bottom of the front side and the rear side of the frame 4.

[0033] Specifically, as Figure 3 shown, protection nets 503 are arranged on the front side and the rear side of the frame 4, positioning columns 504 are fixedly connected to the top and the bottom inside the protection nets 503, and the positioning columns 504 are clamped inside the positioning holes 501.

[0034] Specifically, asFigure 3 As shown, magnetic sheets 505 are embedded in both the top and bottom inside the protective net 503, and the magnetic sheets 505 are magnetically connected to the magnetic absorption sheets 502.

[0035] In this embodiment: By means of the positioning posts 504 on the top and bottom inside the protective net 503, they can be accurately clamped into the positioning holes 501 on the front and rear sides of the frame 4, realizing the rapid positioning and preliminary fixation of the protective net 503. At the same time, the magnetic sheets 505 embedded in the top and bottom inside the protective net 503 are magnetically connected to the magnetic absorption sheets 502 embedded on the frame 4. This double fixation method not only makes the installation of the protective net 503 more firm, but also the operation is simple and convenient. Moreover, through the protective net 503, various sundries and garbage carried in the water body of the water conservancy project can be effectively intercepted, such as branches, leaves, plastic garbage, etc. Its large-area mesh structure can block larger-sized sundries from directly entering the inside of the frame 4, reducing the potential interference of the sundries to the internal monitoring components.

[0036] Specifically, as Figure 5 shown, a turntable 13 is fixedly connected to the top of the push cone rod 204, and a connecting threaded sleeve 14 is fixedly connected to the outer side of the bottom of the turntable 13.

[0037] Specifically, as Figure 5 shown, a threaded ring hole 15 is opened at the top of the positioning cone 201, and the threaded ring hole 15 is located at the bottom of the connecting threaded sleeve 14.

[0038] In this embodiment: The turntable 13 fixedly connected to the top of the push cone rod 204 provides a convenient operating handle for the operator. And when installing the device at the bottom of the water, the operator can rotate the turntable 13 to thread the connecting threaded sleeve 14 at its bottom with the threaded ring hole 15 at the top of the positioning cone 201, thereby forming a stable threaded connection structure to ensure the stability of the push cone rod 204.

[0039] Specifically, as Figure 6 shown, the auxiliary sliding structure 8 includes a frame box 801 bolted to the outside of the slider 7, and fixed rods 802 are fixedly connected to both the front and rear sides inside the frame box 801.

[0040] Specifically, as Figure 6 shown, an auxiliary shaft 803 is rotatably connected to the inner side of the fixed rod 802, and the surface of the auxiliary shaft 803 contacts the inner wall of the inside of the frame 4.

[0041] In this embodiment: Inside the box 801 bolted to the outside of the slider 7, there are a fixed rod 802 and an auxiliary shaft 803. The surface of the auxiliary shaft 803 contacts the inner wall inside the frame 4. When the slider 7 slides on the slide rod 6, the auxiliary shaft 803 will roll along with the movement of the slider 7, converting the sliding friction between the slider 7 and the inner wall of the frame 4 into rolling friction. The resistance of rolling friction is much smaller than that of sliding friction, thus greatly reducing the resistance suffered by the slider 7 during the sliding process. Moreover, the rotational connection mode of the shaft inside the box 801 and its contact with the inner wall of the frame 4 provide additional support and guiding effects for the slider 7.

[0042] Working principle: During the use of the water level monitoring structure in water conservancy projects, by inserting the positioning cone 201 into the bottom mud, a preliminary fixing effect is provided for the entire device. Then, the push cone rod 204 is pushed downward. While it moves downward, the outer side of its bottom exerts a squeezing effect on the lateral support positioning rod 203. Under the thrust of the push cone rod 204, the lateral support positioning rod 203 extends outward from the inclined hole 202 on the outside of the positioning cone 201. After the lateral support positioning rod 203 extends out, it forms a certain angle with the positioning cone 201 and inserts into the mud around the bottom, thereby increasing the contact area and friction force with the bottom medium. This multi-directional support structure can effectively resist the lateral impact force of the water flow. When the water flow generates a lateral component force on the positioning cone 201, the lateral support positioning rod 203 can provide additional resistance to prevent the positioning cone 201 from shifting. The positioning columns 504 at the top and bottom inside the protective net 503 are clamped in the positioning holes 501 on the front and rear sides of the frame 4 to achieve rapid positioning and preliminary fixing. At the same time, the magnet pieces 505 embedded at the top and bottom inside the protective net 503 are magnetically connected to the magnetic attraction pieces 502 embedded on the frame 4, forming a double fixing method, making the installation of the protective net 503 more firm and the operation simple and convenient. The protective net 503 forms a protective barrier on the front and rear sides of the frame 4. When sundries and garbage are carried by the water flow and pass by, the large-area mesh structure of the protective net 503 can block larger-sized sundries from directly entering the inside of the frame 4, avoiding sundries entering the inside of the frame 4 and entangling the slider 7, affecting the buoyancy of the floating ball 10 or jamming the floating rod, ensuring the normal operation of the internal monitoring components, thereby achieving accurate monitoring of water level changes, improving the accuracy and stability of water level monitoring, extending the service life of the device, and making it more adaptable to the complex water environment of water conservancy projects. During this process, as the water level rises or falls, the floating ball 10 is affected by the buoyancy of the water and drives the floating plate 9 to move together. The floating plate 9 slides on the slide rod 6 through the slider 7. The scale rod 12 bolted to the top of the floating plate 9 slides in the chute 11 on the top of the frame 4. By observing the position change of the scale rod 12 in the chute 11, the change of the water level can be accurately read, achieving accurate monitoring of the water level.

[0043] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
