Description

Technical Field

[0001] The utility model belongs to the technical field of water level measuring devices, and in particular relates to a novel tailwater level measuring device for a hydropower station. Background Art

[0002] A hydropower station consists of hydraulic systems, mechanical systems, and power generation devices. It is a key water conservancy project that realizes the conversion of water energy into electrical energy. The sustainability of electricity production requires the uninterrupted utilization of water energy in the hydropower station. The tailwater level measuring device of a hydropower station is a device specially used to measure the river water level at the outlet of the tailwater pipe of a hydropower station. It is an indispensable part of the monitoring and control system of the hydropower station and is of great significance for ensuring the stable operation and power generation efficiency of the hydropower station.

[0003] During the process of hydroelectric power generation at a hydropower station, it is usually necessary to detect the water level of the reservoir in the hydropower station in order to know the water level in the reservoir. However, the existing water level measuring device does not have an early warning function during the measurement process, and thus cannot remind the staff in time, which leads to the risk of accidents. Utility Model Content

[0004] In view of the problems in the related technologies, the present invention proposes a novel tailwater level measuring device for a hydropower station to overcome the above technical problems existing in the existing related technologies.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a novel tailwater level measuring device for a hydropower station, comprising a fixed plate, wherein the fixed plate is slidably connected to a protective tube, the protective tube is slidably connected to a guide rod through a connecting mechanism, a fixed plate is provided inside the protective tube, a battery pack is fixedly installed above the fixed plate, one end of a return spring is fixedly installed below the fixed plate, the other end of the return spring is fixedly installed on a sealing ring, a first floating plate is fixedly installed on the sealing ring, an electrode rod is provided on the sealing ring, the electrode rod is electrically connected to the battery pack, the battery pack is electrically connected to a buzzer and a warning light, and a limit plate is provided on the top of the fixed plate.

[0007] Furthermore, the fixing plate is fixedly mounted inside the protective tube, the reset spring is sleeved outside the electrode rod, and the first floating plate is fixedly mounted on a side of the sealing ring away from the electrode rod.

[0008] Furthermore, the electrode rod is fixedly mounted on the sealing ring, the buzzer and the warning light are fixedly mounted on the cover plate, the cover plate is movably mounted on the top of the protective tube, and the fixing plate is fixedly mounted on the reservoir wall by bolts.

[0009] Furthermore, the connecting mechanism includes a connecting rod provided on the protective tube, a sliding block is fixedly mounted on the connecting rod, and the sliding block is slidably connected to the guide rod.

[0010] Furthermore, a second floating plate is fixedly mounted on the bottom of the sliding block, a rod is fixedly mounted on the sliding block, and the rod is slidably connected to the fixed plate.

[0011] Furthermore, the guide rod is provided with a plurality of reflective scale stickers, and the limiting plate is fixedly mounted with a lighting lamp.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model proposes a novel tailwater level measuring device for a hydropower station. By adopting a coordinated design of a first floating plate and an electrode rod, it achieves accurate early warning of the tailwater level of the hydropower station. When the water level rises, the first floating plate rises due to buoyancy, driving the electrode rod to insert into the battery pack, thereby triggering a buzzer and warning light to sound an alarm, reminding staff to take timely countermeasures. This design is not only simple in structure and easy to operate, but also has high early warning accuracy, which can greatly reduce the safety risks caused by abnormal water levels in hydropower stations.

[0014] 2. The utility model also realizes the stable guidance of the protective tube and the intuitive observation of water level changes through the design of the connecting mechanism, including the sliding block, the guide rod and the reflective scale. When the water level rises, the sliding block and the rod will rise along the fixed plate, and the protective tube will rise accordingly. At the same time, the reflective scale can clearly show the rising water level. In addition, the setting of the lighting further improves the convenience of observation, so that the staff can accurately read the water level scale even at night or in a dimly lit environment. This design not only improves the accuracy and reliability of water level measurement, but also provides a strong guarantee for the safe operation of the hydropower station.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0024] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0025] See also Figures 1-4 As shown, the utility model is a novel tailwater level measuring device for a hydropower station, comprising a fixed plate 1, the fixed plate 1 being slidably connected to a protective tube 2, the protective tube 2 being slidably connected to a guide rod 3 through a connecting mechanism, a fixed plate 4 being provided inside the protective tube 2, a battery pack 5 being fixedly mounted above the fixed plate 4, one end of a return spring 6 being fixedly mounted below the fixed plate 4, the other end of the return spring 6 being fixedly mounted on a sealing ring 7, a first floating plate 12 being fixedly mounted on the sealing ring 7, an electrode rod 8 being provided on the sealing ring 7, the electrode rod 8 being electrically connected to the battery pack 5, the battery pack 5 being electrically connected to a buzzer 9 and a warning light 10, and a limit plate 11 being provided on the top of the fixed plate 1.

[0026] The working principle of a new type of tailwater level measuring device for a hydropower station proposed by the present invention is as follows: first, a fixed plate 1 is fixedly installed on the wall of the reservoir; when the water level rises, the first floating plate 12 rises due to the buoyancy, thereby driving the protective tube 2 to rise; when the water level reaches the warning limit, the protective tube 2 will be unable to continue to rise due to the action of the limit plate 11; at this time, the first floating plate 12 drives the sealing ring 7 to move upward, thereby driving the electrode rod 8 to move upward, and then the electrode rod 8 is inserted into the interior of the battery pack 5, thereby achieving electrical connection, and then the water level warning is reminded to the staff through the buzzer 9 and the warning light 10.

[0027] It is worth noting that when the electrode rod 8 is inserted into the battery pack 5, the reset spring 6 undergoes elastic deformation and maintains a certain tension. After the water level drops, the reaction force of the reset spring 6 is used to drive the electrode rod 8 to reset, thereby releasing the electrical connection with the battery pack 5.

[0028] In one embodiment, the fixing plate 4 is fixedly mounted inside the protective tube 2 , the return spring 6 is sleeved outside the electrode rod 8 , and the first floating plate 12 is fixedly mounted on the side of the sealing ring 7 away from the electrode rod 8 .

[0029] In one embodiment, for the above-mentioned electrode rod 8, the electrode rod 8 is fixedly mounted on the sealing ring 7, the buzzer 9 and the warning light 10 are fixedly mounted on the cover plate 13, the cover plate 13 is movably mounted on the top of the protective tube 2, and the fixing plate 1 is fixedly mounted on the reservoir wall by bolts 14.

[0030] In one embodiment, the connecting mechanism includes a connecting rod 15 provided on the protective tube 2 , a sliding block 16 is fixedly mounted on the connecting rod 15 , and the sliding block 16 is slidably connected to the guide rod 3 .

[0031] In one embodiment, for the sliding block 16 , a second floating plate 17 is fixedly mounted on the bottom of the sliding block 16 , and a rod 18 is fixedly mounted on the sliding block 16 , and the rod 18 is slidably connected to the fixed plate 1 .

[0032] In one embodiment, for the guide rod 3 , a plurality of reflective scale stickers 19 are provided on the guide rod 3 , and a lighting lamp 20 is fixedly installed on the limiting plate 11 .

[0033] The working principle of the novel tailwater level measuring device of a hydropower station proposed in the present invention is that when the water level rises, the first floating plate 12 and the second floating plate 17 are synchronously driven to rise, thereby driving the sliding block 16 and the rod 18 to rise along the fixed plate 1, thereby achieving a guiding effect on the protective tube 2 so that it does not rotate.

[0034] It is worth noting that the rising water level can be observed through the reflective scale sticker 19 , and the scale of the reflective scale sticker 19 can be further observed through the lighting lamp 20 .

[0035] Furthermore, when the water level remains constant, an ultrasonic water level meter can be used to measure the water level. This instrument uses an ultrasonic probe to emit ultrasonic pulses, which travel through the air and are reflected at the gas-liquid interface. The time difference between the transmitted and received signals is measured and converted into an electrical signal for output, thereby determining the actual water level.
