Description
Technical Field
[0001] This utility model relates to the field of water conservancy measurement technology, and in particular to a water level benchmark for water conservancy and hydropower. Background Technology
[0002] Water level gauges for water conservancy and hydropower projects, also known as water gauges, are the most basic and intuitive water level observation facilities in water conservancy and hydropower projects. They are like a "giant ruler" inserted vertically into the water, and through the clear scale on them, people can directly read the height of the water surface. They are mainly used for reservoir scheduling, flood control early warning, hydropower generation and other fields.
[0003] To facilitate intuitive observation of water levels by monitoring personnel, a buoy can be installed inside the level gauge. The buoy rises and falls synchronously with changes in water level. For example, Chinese Patent Publication No. CN223107035U discloses a water level level gauge, including an outer cylinder with a marker rod movably inserted inside. Both the outer cylinder and the marker rod are provided with scale lines. A marker float ring is fitted outside the outer cylinder and connected to the marker rod. During operation, as the water level rises, it can push the marker float ring and the marker rod to rise synchronously. This utility model can improve the convenience of reading water level scales for staff, making it easier for staff in different positions to intuitively read data. It has a simple structure, is easy to use, and is highly practical.
[0004] In actual operation, the buoy and the outer cylinder slide up and down through a moving groove. However, considering that the outer cylinder is not equipped with a filter structure in the moving groove, the buoy is immersed in the river water for a long time. The mud and sand impurities in the water directly enter the interior of the buoy, and the attached impurities can easily affect the normal use of the buoy and the buoy. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where the moving trough lacks a filtration structure, allowing silt and impurities to enter the level indicator. This invention provides a water level indicator for water conservancy and hydropower projects.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a water level indicator for water conservancy and hydropower, which consists of an indicator body and a float. The float is slidably connected to the inside of the indicator body through a bracket. Several water inlet holes are provided on the periphery of the indicator body, and a filter screen is detachably connected to the water inlet holes through an elastic structure.
[0008] The bracket also includes a cleaning component on the periphery of the main body of the pole, which is used to clean impurities from the surface of the main body of the pole and the filter screen.
[0009] Furthermore, the main body of the marker has a cylindrical structure, and its outer wall is evenly distributed with a number of water inlet holes along the length direction;
[0010] The bracket includes a top seat, which is threadedly connected to and sealed in the top opening of the main body of the marker. Two support rods are fixedly connected to the bottom of the top seat, and the float is slidably connected to the periphery of the support rods through the connecting parts on both sides of the outer wall.
[0011] Furthermore, the elastic structure includes an elastic element, which is annular and adapted to the water inlet. The two ends of the elastic element have a stop portion and a protrusion, respectively. The opposite sides of the stop portion and the protrusion are both arc-shaped structures adapted to the main body of the marker.
[0012] Furthermore, the protrusion forms several elastic portions through the first deformation groove, and the elastic portions pass through the water inlet hole through abutment deformation;
[0013] The protrusion and the stop respectively abut against the inner and outer sides of the main body of the marker.
[0014] Furthermore, the cleaning assembly includes a connecting rod, which has a U-shaped structure, with both ends slidably connected to the top seat, and is also disposed on the periphery of the main body of the marker pole;
[0015] Cleaning components are slidably connected to both ends of the connecting rod, and the two cleaning components are attached to the outer wall of the main body of the pole.
[0016] Furthermore, the connecting rod is provided with two annular protrusions on the periphery of both shaft ends, and the connecting rod is also provided with a second deformation groove through the bottom annular protrusion on the shaft end, and the cleaning component is stopped between the two annular protrusions by abutting deformation.
[0017] The connecting rod is fixed to the top seat by a retaining bracket.
[0018] The water level indicator proposed in this utility model has the following advantages: In this utility model, several water inlet holes are evenly distributed along the length of the outer periphery of the indicator body. The setting of multiple water inlet holes can ensure that the indicator can be used for water levels of different heights within a certain range. After water enters the inside of the indicator body, the float moves up and down along the support rod under the action of buoyancy. The setting of the float ball can enable the monitoring personnel to better observe the changes in water level.
[0019] A filter screen is detachably connected to the water inlet via an elastic structure. The filter screen filters out mud and impurities in the water. In addition, a cleaning component can be used to clean mud and impurities attached to the outside of the main body of the marker to avoid affecting observation. Attached Figure Description

[0026] 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.
[0027] Reference Figure 1-5 A water level indicator for water conservancy and hydropower is composed of a main body 1 and a float 2. The float 2 is slidably connected inside the main body 1 through a bracket 3. The main body 1 is provided with several water inlet holes 4, and a filter screen 6 is detachably connected inside the water inlet holes 4 through an elastic structure 5.
[0028] The bracket 3 is provided with a cleaning component 7 on the periphery of the main body 1 of the pole. The cleaning component 7 is used to clean impurities on the surface of the main body 1 of the pole and the filter screen 6.
[0029] In some embodiments, a base is fixedly connected to the bottom of the main body 1 of the marker pole, and a number of fixed anchors are connected to the base. The main body 1 of the marker pole is fixed by the fixed anchors and the base.
[0030] The main body 1 of the marker is preferably made of a transparent material, such as a transparent pressure plate or glass. After water enters the interior of the main body 1 through the water inlet 4, the water level inside the main body 1 is kept consistent with the external water level under the pressure of the water. Thus, the main body 1 has several water inlets 4 evenly distributed along its length, so that it can monitor the water level at different heights within a certain range.
[0031] In this embodiment, a filter screen 6 is provided to filter out mud and sand impurities in the water, and a cleaning component 7 is provided to clean the outer periphery of the main body 1 of the marker, preventing them from adhering and accumulating on the inner and outer walls of the main body 1 of the marker. Those skilled in the art will understand that after long-term use, it is still necessary to disassemble and clean the main body 1 of the marker, the float 2, the filter screen 6, the cleaning component 7, and the elastic structure 5. Therefore, it is not possible to rely solely on the filter screen 6 and the cleaning component 7 to ensure that the main body 1 remains free of impurities for a long time.
[0032] Furthermore, the main body 1 of the marker has a cylindrical structure, and its outer wall is evenly distributed with a number of water inlet holes 4 along the length direction;
[0033] The bracket 3 includes a top seat 31, which is threadedly connected to and sealed in the top opening of the main body 1. Two support rods 32 are fixedly connected to the bottom of the top seat 31. The float 2 is slidably connected to the periphery of the support rods 32 through the connecting parts 21 on both sides of the outer wall.
[0034] In this embodiment, refer to Figure 2 , 4 As shown, a threaded seat can be fixedly connected to the inner top opening of the main body 1. The main body 1 and the top seat 31 are threadedly connected through the threaded seat, so that the main body 1 and the float 2 and other components can be disassembled and cleaned.
[0035] Specifically, the connecting part 21 is slidably connected to the support rod 32 through the shaft hole. To ensure smooth sliding between the float 2 and the support rod 32, the shaft hole can be slightly larger than the diameter of the support rod 32. Then, the float 2 will rise and fall along the support rod 32 under the action of buoyancy, preventing large friction from affecting the rise and fall of the float 2.
[0036] More specifically, a sealing gasket is provided between the ground of the top seat 31 and the top of the main body 1 of the marker pole to improve the sealing effect and prevent mud and sand impurities from entering.
[0037] Furthermore, the elastic structure 5 includes an elastic element 51, which is annular and adapted to the water inlet 4. The two ends of the elastic element 51 have a stop portion 52 and a protrusion 53, respectively. The opposite sides of the stop portion 52 and the protrusion 53 are both arc-shaped structures adapted to the main body 1 of the marker.
[0038] More specifically, the protrusion 53 forms a plurality of elastic parts 55 through the first deformation groove 54, and the elastic parts 55 pass through the water inlet hole 4 through abutment deformation;
[0039] The protrusion 53 and the stop 52 respectively abut against the inner and outer sides of the main body 1 of the marker.
[0040] In this embodiment, the elastic element 51, the connecting rod 71, and the card holder 75 are preferably made of materials with deformation capabilities such as rubber and plastic. The filter screen 6 can be chemically bonded to the end face of the elastic element 51. After long-term use, the filter screen 6 and the elastic element 51 can be replaced by replacing the whole thing.
[0041] Specifically, such as Figure 3 As shown, the opposing surfaces of the stop part 52 and the protrusion part 53 are matched with the inner and outer walls of the marker body 1, so that after the elastic element 51 is fixed in the water inlet hole 4, the tight fit prevents mud and sand impurities from entering the marker body 1. Of course, a sealing gasket can also be set on the side of the stop part 52 to further improve the sealing effect.
[0042] More specifically, when the elastic element 51 is installed, the protrusion 53 deforms against the main body 1 under the action of the first deformation groove 54, avoids the deformation, and after the deformation is restored, it is fixed in the water inlet hole 4 in conjunction with the stop part 52.
[0043] In general, the cleaning assembly 7 includes a connecting rod 71, which has a U-shaped structure and is slidably connected to the top seat 31 at both ends, and is also disposed on the periphery of the marker body 1;
[0044] Cleaning components 72 are slidably connected to both ends of the connecting rod 71, and the two cleaning components 72 are attached to the outer wall of the main body 1 of the marker.
[0045] Finally, the connecting rod 71 is provided with two annular protrusions 73 on the periphery of both shaft ends, and the connecting rod 71 is also provided with a second deformation groove 74 that penetrates the bottom annular protrusions 73 on the shaft end. The cleaning member 72 is stopped between the two annular protrusions 73 by abutting deformation.
[0046] The connecting rod 71 is fixed to the top seat 31 by a retaining bracket 75.
[0047] In this embodiment, as Figure 4 As shown, the connecting rod 71 and the cleaning component 72 are connected by the second deformation groove 74 and the two annular protrusions 73, which are disassembled and assembled by means of abutment deformation, to prevent the cleaning component 72 from losing its cleaning ability after long-term use;
[0048] Specifically, the cleaning component 72 is equipped with a sponge or flexible cloth on the inner wall of the ring, which cleans the outer wall of the main body 1 by sliding up and down;
[0049] There is a gap between the two cleaning parts 72. When the parts slide up and down through the gap, they avoid the filter screen 6, preventing some impurities from entering the interior of the main body 1 due to the cleaning resistance of the cleaning parts 72. Therefore, the filter screen 6 can be removed for individual cleaning.
[0050] It should be added that the cleaning component 72 is attached to the outer periphery of the main body 1 of the marker pole. Therefore, when the cleaning component 72 is in a limited position, a connecting rod 71 can also prevent the cleaning component 72 from shifting during the lifting and lowering process.
[0051] Furthermore, the card holder 75 secures the connecting rod 71 by engaging and fixing it with the top engaging slot.
[0052] Working method: The main body 1 of the marker is fixed by a fixed anchor. After the anchor is fixed, water enters the interior of the main body 1 through the water inlet 4. Under the buoyancy of the water, the float 2 slides along the support rod 32 through the connecting part 21. The sliding indicator helps the monitoring personnel to monitor.
[0053] Before the water enters the interior of the main body 1, it will pass through the filter screen 6. The filter screen 6 filters out the mud and sand impurities in the water. When cleaning and replacing the filter screen 6, the elastic part 51 is pulled out directly. During the pulling process, the protrusion 53 is deformed by the first deformation groove 54 to avoid the object and can be disassembled. The installation method is the same.
[0054] Finally, after use, the cleaning component 72 can be driven up and down by the connecting rod 71 to clean the outer wall of the main body 1 of the marker. The cleaning component 72 and the connecting rod 71 can also be disassembled and replaced.
[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
