Description

Technical Field

[0001] This invention belongs to the technical field of reservoir water level measurement equipment, specifically to an attached dual-mode polyester water gauge for pumped storage power stations. Background Technology

[0002] In pumped storage power stations, water gauges are usually installed at different heights on the reservoir bank to clearly indicate the water level.

[0003] Currently, there are three common types of water level gauges used in reservoirs. The first type is a column partially buried in the reservoir bank slope. The column is set vertically, and the measuring scale lines are engraved on the column, or an enamel water level gauge is installed on the column to form a column-type water level gauge. The second type is a stainless steel water level gauge anchored to the reservoir bank slope with bolts. The third type is a painted water level gauge, which is a water level scale line painted on the reservoir bank slope by hand. Of the three types of water gauges mentioned above, while they allow for direct measurement of water levels in reservoirs, the column-type water gauge requires drilling holes in the reservoir surface to vertically fix the column when installed in the asphalt concrete impermeable type pumped storage power station basin. This drilling process can easily damage the asphalt concrete impermeable layer, creating leakage channels and posing a threat to the basin's impermeability and safety. Stainless steel water gauges require drilling holes in the reservoir surface for bolt anchoring, which also damages the asphalt concrete impermeable layer. Painted water gauges are applied directly to the asphalt concrete impermeable layer manually and have no adverse effects on the impermeable structure. However, under conditions of exposure to direct sunlight and repeated immersion in reservoir water, the paint will fade rapidly, making it difficult for the human eye to clearly read the water gauge markings, resulting in poor performance. Summary of the Invention

[0004] To address the problem that conventional water gauge installation requires holes on the reservoir surface for fixing, which can easily damage the asphalt concrete anti-seepage layer, this invention provides an attached dual-mode polyester water gauge for pumped storage power stations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention proposes an attached dual-mode polyester water gauge for a pumped storage power station, comprising a fixing component installed on the top of the reservoir basin bank slope, a water gauge strip connected to the fixing component, the water gauge strip being laid along the reservoir basin bank slope, and the bottom of the water gauge strip being located at the bottom of the reservoir. The water gauge is equipped with water level scale lines; multiple balancing components are evenly spaced on the water gauge. The balancing assembly includes a connecting plate disposed at the bottom of the water gauge strip, the connecting plate being disposed along the width of the water gauge strip, and counterweights being disposed at both ends of the connecting plate.

[0006] Preferably, a limiting head is provided on the end of the connecting plate, and the limiting head is connected to the counterweight via a steel wire rope.

[0007] Preferably, the counterweight is one of a sandbag or a weighing belt containing stainless steel fragments.

[0008] Preferably, the width of the water gauge is set to 3m.

[0009] Preferably, the water level gauge is a polyester tape, and the water level markings are painted on the polyester tape.

[0010] Preferably, the fixing component includes a fixing base, which is buried near its bottom at the top of the reservoir bank slope. A suspension rod is provided on the fixing base, and a suspension component is connected to the suspension rod. The suspension component is fixed to the top of the water gauge.

[0011] Preferably, a reinforcing T-shaped plate is provided on the bottom end face of the fixing seat, and a stiffening plate is provided on the T-shaped plate.

[0012] Preferably, the suspension assembly includes a connecting rod fixed to the top end of the water gauge, a connecting ring provided on the connecting rod, the connecting ring being hung on the suspension rod, and an anchor rod provided at the end of the connecting rod, the anchor rod being fixed at the top position of the reservoir bank slope. Preferably, the fixing base is provided with a water level recovery assembly, which includes a recovery rope and two support plates; The two support plates are vertically fixed on the fixed base, and a rotating shaft is provided between the two support plates. A winch is provided on the rotating shaft. The recovery rope is located on the side of the water gauge belt, with one end of the recovery rope fixed to the winch and the other end of the recovery rope fixed to the end of the water gauge belt located at the bottom of the reservoir.

[0013] Preferably, a piezometer is installed at the end of the water gauge located at the bottom of the reservoir, and a data acquisition device is installed on the side of the fixing base, the data acquisition device being communicatively connected to the piezometer.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: This invention proposes an attached dual-mode polyester water gauge for pumped storage power stations. One end of the water gauge is fixed to the top of the reservoir bank slope using a fixing component. A balancing component is then installed on the water gauge, with a counterweight within the balancing component causing the other end of the water gauge to sink to the reservoir bottom. The lower end of the water gauge at other locations is in contact with the surface of the reservoir bank slope. The counterweight provides balance, anti-buoyancy, anti-wave, and anti-warping functions, ensuring the water gauge is stably fixed to the reservoir bank slope surface. This allows for direct observation of the water level data in the reservoir, avoiding drilling holes or other fixing structures on the reservoir bank slope, preventing damage to the asphalt concrete anti-seepage layer on the reservoir bank slope, and improving the safety of the reservoir.

[0015] Furthermore, this water gauge incorporates a limiting head at the end of the connecting plate. The limiting head is connected to a counterweight via a steel wire rope. Through the synergistic effect of the elastic connection formed by the steel wire rope and the inertial mass of the counterweight, the mechanical vibration energy of the reservoir area can be absorbed, reducing the swaying amplitude of the water gauge under frequent start-stop conditions of the pumped storage unit, thereby ensuring the stable operation of the water gauge in its installation position on the reservoir.

[0016] Furthermore, the reinforcing T-shaped plate and stiffening plate provided on the bottom end face of the fixing seat in this water gauge increase the stability of the fixing seat at the top position of the reservoir bank slope, and provide a stable support structure for the water gauge at the top position of the reservoir bank slope.

[0017] Furthermore, the connecting ring in this water gauge works in conjunction with the suspension rod to connect the upper end of the water gauge strip to the fixing seat, thereby fixing the upper end of the water gauge strip to the top of the reservoir basin slope. It is further fixed by the anchor rod so that the water gauge strip is stably installed on the reservoir basin slope.

[0018] Furthermore, in this water gauge, the retrieval rope in the water gauge retrieval assembly is fixed to the side of the water gauge belt. In conjunction with the winch, the retrieval rope is retrieved or lowered, thereby realizing the retrieval or lowering of the water gauge belt, improving the convenience of water gauge belt installation and maintenance efficiency.

Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] This invention proposes an attached dual-mode polyester water gauge for pumped storage power stations, such as... Figures 1-4 As shown, it includes a fixing component 1 installed at the top of the reservoir basin bank slope, a water level gauge 4 connected to the fixing component 1, the water level gauge 4 being laid along the reservoir basin bank slope, and the bottom of the water level gauge 4 being located at the bottom of the reservoir; water level scale lines are set on the water level gauge 4; the width of the water level gauge 4 is set to 3m, the water level gauge 4 is a polyester belt, and the water level scale lines are painted on the polyester belt.

[0027] like Figure 1 and Figure 3 As shown, multiple balancing components 5 are evenly spaced on the water gauge belt 4. Each balancing component 5 includes a connecting plate 50 disposed on the lower end face of the water gauge belt 4. The connecting plate 50 is positioned along the width of the water gauge belt 4, meaning its length direction is the same as the width direction of the water gauge belt 4. Counterweights 51 are respectively disposed at both ends of the connecting plate 50. In this water gauge belt, it is fixed at the top of the reservoir bank slope by a fixing component 1. The water gauge belt 4 slides along the surface of the reservoir bank slope to the bottom of the reservoir. The balancing components 5 ensure that the lower end face of the water gauge belt 4 is in contact with the surface of the reservoir bank slope, thus providing balance, anti-buoyancy, anti-wind and wave resistance, and anti-warping functions, thereby stabilizing the water gauge belt 4. The water gauge 4 is fixed to the surface of the reservoir bank slope, eliminating the influence of external factors on its use and allowing for direct observation of the water level data in the reservoir. In this water gauge, the water gauge 4 is fixed by the balancing component 5, avoiding drilling holes or setting other fixed structures on the reservoir bank slope, thus preventing damage to the asphalt concrete anti-seepage layer on the reservoir bank slope and improving the safety of the reservoir. At the same time, when the water level scale lines in the water gauge 4 fixed by the balancing component 5 are worn or unclear, the water gauge 4 can be removed from the fixing component 1 and then pulled out of the reservoir by the dragging equipment to replace it with a new water gauge 4.

[0028] like Figure 1 and Figure 3As shown, limit heads 52 are provided at both ends of the connecting plate 50. The limit heads 52 are connected to the counterweights 51 by steel wire ropes. The counterweights 51 are either sandbags or weighing belts filled with stainless steel fragments. The limit heads 52 form a physical barrier structure, which, together with the flexible connection of the steel wire ropes, constructs a double anti-drop mechanism. Even under the condition of water flow impact, the reliable connection between the counterweights 51 and the connecting plate 50 can still be ensured. At the same time, the elastic connection formed by the steel wire ropes and the inertial mass of the counterweights 51 work together to absorb the mechanical vibration energy of the reservoir area and reduce the sway amplitude of the water draft belt 4 under the frequent start-stop conditions of the pumped storage unit.

[0029] like Figures 1-4 As shown, the fixing component 1 includes a fixing base 10, which is buried near its bottom at the top of the reservoir bank slope. Multiple suspension rods 12 are provided on one end face of the fixing base 10 opposite to the reservoir. The multiple suspension rods 12 are arranged horizontally, and a suspension component 2 is connected to the suspension rod 12. The suspension component 2 is fixed to the top of the water level gauge 4. The detachable connection between the suspension component 2 and the fixing component 1 allows the water level gauge 4 to be disassembled from the fixing base 10. When the water level scale on the water level gauge 4 is worn or the water level gauge 4 is damaged, the suspension component 2 can be removed from the fixing base 10 and a new water level gauge 4 can be replaced, shortening maintenance time and improving maintenance efficiency.

[0030] like Figure 1 and Figure 2 As shown, a reinforcing T-shaped plate 11 is provided on the bottom end face of the fixing seat 10, and a stiffening plate 13 is provided on the reinforcing T-shaped plate 11. When the fixing seat 10 is buried near its bottom position at the top position of the reservoir bank slope, both the reinforcing T-shaped plate 11 and the stiffening plate 13 are buried at the top position of the reservoir bank slope, thereby strengthening the stability of fixing the fixing seat 10.

[0031] like Figure 1 and Figure 2 As shown, the suspension assembly 2 includes a connecting rod 20 fixed to the top end of the water gauge belt 4. The connecting rod 20 is arranged along the width direction of the water gauge belt 4. Multiple connecting rings 21 are arranged on the side of the connecting rod 20 away from the water gauge belt 4. The connecting rings 21 correspond one-to-one with the suspension rods 12. The connecting rings 21 are hung on the suspension rods 12 to connect the upper end of the water gauge belt 4 to the fixing seat 10. The upper end of the water gauge belt 4 is fixed at the top position of the reservoir bank slope. Anchor rods 22 are provided at both ends of the connecting rod 20. The anchor rods 22 are fixed at the top position of the reservoir bank slope to further fix the upper end of the water gauge belt 4 and increase the stability of the water gauge belt in the reservoir.

[0032] like Figures 1-4As shown, a water level recovery assembly 6 is provided on the upper end face of the fixed base 10. The water level recovery assembly 6 includes a recovery rope 60 and two support plates 61. The two support plates 61 are vertically fixed on the upper end face of the fixed base 10 and are parallel to each other. The distance between the two support plates 61 is greater than the width of the water level belt 4. A rotating shaft 63 is provided between the two support plates 61. The axis of the rotating shaft 63 is parallel to the wide side of the water level belt 4. A motor 64 or a handle is provided at the end of the rotating shaft 63. Two winches 62 are arranged parallel to each other on the rotating shaft 63 at the position between the two support plates 61. The winches 62 are aligned with the side of the water level belt 4. The recovery rope 60 is set on the side of the water level gauge belt 4, with one end of the recovery rope 60 fixed to the winch 62 and the other end fixed to the end of the water level gauge belt 4 located at the bottom of the reservoir. When the water level gauge belt 4 needs to be recovered or lowered, the winch 62 is rotated by rotating the rotating shaft 63, which winds the recovery rope 60 set on the side of the water level gauge belt 4 onto the winch 62 or releases it from the winch 62. The recovery rope 60 is fixed to the side of the water level gauge belt 4 through the water level gauge recovery assembly 6, and the recovery rope 60 is recovered or lowered in conjunction with the winch 62, thereby realizing the recovery or lowering of the water level gauge belt 4, improving the convenience of installation of the water level gauge belt 4 and improving maintenance efficiency.

[0033] like Figure 1 and Figure 3 As shown, a piezometer 7 is installed at the end of the water gauge 4 located at the bottom of the reservoir, and a data acquisition instrument 3 is installed on the side of the fixed base 10. The data acquisition instrument 3 is connected to the piezometer 7 via communication.

[0034] This invention relates to an adhesive dual-mode polyester water level gauge that attaches to the reservoir bank surface using the slope and its own weight. This effectively overcomes the damage to the asphalt concrete anti-seepage layer caused by traditional pile-type water level gauges and replaces the shortcomings of traditional paint-based water level gauges, such as rapid aging and unclear graduations. The polyester material used possesses properties of aging resistance, corrosion resistance, high strength, and resistance to deformation. Paint applied to its surface adheres strongly and is not easily faded. This allows for efficient and accurate measurement of reservoir water levels using both manual and automated modes without damaging the reservoir's anti-seepage structure.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the scope of the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
