Description

Technical Field

[0001] This utility model relates to the field of hydrological observation technology, and in particular to a parallel power transmission device for hydrological cableways. Background Technology

[0002] Currently, hydrological cableways are crucial devices for river hydrological data measurement. In the evolution of hydrological measurement from manual to all-weather, automated, and unattended operations, power supply has always been a significant issue. Current power supply methods include battery power and solar panel power. Battery power suffers from drawbacks such as heavy weight and short self-sustaining time. Solar panel power systems, consisting of solar panels, a solar charge / discharge controller, and energy storage batteries, are heavy and complex, increasing the weight of the pod, the burden on the main cable and circulation cable, and reducing the lifespan of the main cable and circulation cable. Furthermore, the large wind-exposed surface of solar panels can affect the stability of pod measurements and the cableway's lifespan in windy areas. In northern regions, especially the cold and arid northeast and northwest of my country, where river ice periods are long, the pod requires ice breaking, de-icing, and insulation during hydrological measurements, resulting in high power consumption. Relying on small solar panels makes it difficult to support long-term, continuous, stable, fully automated, and unattended measurement tasks.

[0003] Therefore, a parallel power transmission device for hydrological cableways is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a parallel power transmission device for hydrological cableways. This utility model adds at least one dedicated power transmission cable to the cableway system to connect to the mains power supply, or sets up a solar power station or wind power station on the riverbank to provide centralized power supply through multiple modes such as mains power, solar power, wind power supply or wind-solar hybrid power supply.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a parallel power transmission device for hydrological cableways, including a pod and a sling, wherein the sling is installed on a tower and the pod is slidably connected to the sling;

[0033] Example 1:

[0034] Figure 1 This is a schematic diagram of the overall assembly structure of this utility model. Figure 2 This is an enlarged structural schematic diagram of the pod 2 in this utility model. Figure 3 This is a schematic diagram of the power receiving mechanism in this utility model, as shown below. Figure 1 , Figure 2 ,and Figure 3 The hydrological cableway parallel power transmission device shown includes a pod 2 and a sling. The sling is installed on the tower 1, and the pod 2 is slidably connected to the sling.

[0035] The slings in this invention include a main sling 3, a power transmission cable 4, and a circulation cable 5. The main sling 3, power transmission cable 4, and circulation cable 5 are arranged in parallel from bottom to top. Two circulation cables 5 are provided, each passing through the upper frame 7 of the gondola. Two power transmission cables 4 are provided; if the power supply is AC, one is connected to the live wire; if the power supply is DC, it is connected to the positive terminal. For the other power transmission cable 4, if the power supply is DC, it is connected to the neutral wire; if the power supply is DC, it is connected to the negative terminal. This invention includes a power transmission cable limiter 13 installed inside the upper frame 7 of the gondola to limit the power transmission cable movement. Device 13 includes an upper concave insulating wheel 14 and a lower concave insulating wheel 15, used to restrict the upward or downward movement of the power transmission cable 4. The power transmission cable limiter 13 allows the power transmission cable 4 to pass through the pod 2 at a fixed position, facilitating the receiver 9 to draw power at a fixed position. The power transmission cable limiter 13 in this utility model can be a circular insulating hole or a roller mechanism composed of a pair of concave wheels 6. The latter has low friction and causes very little wear on the power transmission cable 4 and the power transmission cable limiter 13 itself. This patent does not limit the specific type of power transmission cable limiter 13 used, but only provides an example.

[0036] The pod 2 in this utility model includes a pod upper frame 7, a lifting device 11, and a pod equipment box 12. The pod upper frame 7 and the pod equipment box 12 are connected to each other through the lifting device 11. Specifically, the lifting device 11 includes a steel cable, pulleys, and an electric winch 21. The electric winch 21 completes the lifting and lowering of the pod equipment box 12 by winding or releasing the steel cable. Figure 2 As shown, the lifting device 11 consists of a steel cable and a pulley block. It can also be other types of lifting devices 11, such as chains or lead screws. The lifting device 11 is used to lower the sensor 8 or the working device to a preset height of the measuring vertical line for testing or operation. After the test or operation is completed, the sensor 8 or the working device is raised to enter the test / operation state. A concave wheel 6 is provided above the main cable 3. The concave wheel 6 is connected to the upper frame 7 of the pod. The concave wheel 6 is pressed onto the main cable 3 by gravity. By pulling the two circulating cables 5, the concave wheel 6 can roll on the main cable 3, thereby allowing the pod 2 to move along the main cable 3. In this utility model, the upper frame 7 of the pod is pressed onto the main cable 3 by the gravity of the concave wheel 6 and is connected to the pod equipment box 12 through the lifting device 11.

[0037] This utility model has a power supply controller 10 and a receiver 9 installed on the upper frame 7 of the pod. The power supply controller 10 and the receiver 9 are connected by a wire 20. The receiver 9 is in contact with the power transmission cable 4. There are two receivers 9 in this utility model. The receiver 9 draws power by contacting the power transmission cable 4. The power supply controller 10 is electrically connected to one receiver 9 (live wire or positive cable) and the other receiver 9 (neutral wire or negative cable). Through internal logic circuits or software control, the power is distributed to the various electrical components of the pod 2. The internal components consist of a power input interface, an output interface, a control circuit, a wireless transceiver device, and a power storage device. Specifically, the receiver 9 has a power receiving conductor 1. 6. One end of the current receiving conductor 16 is in contact with the power transmission cable 4, and the other end of the current receiving conductor 16 is connected to the wire 20. An insulating base 19 is provided at the bottom of the current receiving conductor 16, and a spring 17 is installed between the current receiving conductor 16 and the insulating base 19. The spring 17 can maintain a certain pressure between the current receiving conductor 16 and the power transmission cable 4 to ensure the reliability of the electrical connection. One end of the spring 17 is connected to the insulating base 19, and the insulating base 19 and the spring 17 are kept in pressure. The current receiving conductor 16 passes through the hole in the middle. A spring cover 18 is connected to the other end of the spring 17. The spring cover 18 is fixedly connected to the current receiving conductor 16 to maintain a certain pressure on the spring 17.

[0038] In this utility model, the gondola equipment box 12 is connected to the power supply controller 10 by a wire. A sensor 8 or a working device is installed at the bottom of the gondola equipment box 12. The sensor 8 is any one of a flow sensor 8, a water depth sensor 8, or a water quality sensor 8. The working device is any one of an icebreaker or a de-icer.

[0039] Work process description:

[0040] 1. Power Supply Preparation: The receiver 9 on the pod 2 begins operation. The two power cables 4 are connected to the live and neutral wires of AC power (or the positive and negative terminals of DC power), respectively. The spring 17 structure in the receiver 9 ensures stable contact between the current-receiving conductor 16 and the power cables 4, ensuring that the current can be smoothly transmitted to the power controller 10.

[0041] 2. Power Management and Distribution: The power supply controller 10 receives the electrical energy from the power transmission cable 4 and manages and distributes the electrical energy through internal logic circuits or software control systems to provide a stable power supply to various electrical components in the pod 2.

[0042] 3. Start-up and Initial Positioning: After the system is started, the pod 2 is in the initial position. By operating the electric winch 21, the steel cable is released or wound up, so that the pod equipment box 12 reaches the predetermined working height under the control of the lifting device 11.

[0043] 4. Moving to the designated position: The upper frame 7 of the pod is pressed onto the main cable 3 by the concave wheel 6. When movement is required, the circulating cable 5 pulls the pod 2, causing the concave wheel 6 to roll along the main cable 3, thereby moving the entire pod 2 along the preset path to the designated measurement or operation position.

[0044] 5. Task execution: Upon reaching the target location, the sensors 8 (such as flow, water depth, or water quality sensors 8) or operating devices (such as icebreakers or de-icers) installed at the bottom of the pod equipment box 12 begin to perform the corresponding monitoring or maintenance tasks, depending on the specific requirements.

[0045] 6. Mission Completion and Return: After completing the mission, the pod 2 returns to its initial position or the next work point under the traction of the circulation cable 5. During this process, the power controller 10 continues to manage electrical energy to ensure the normal operation of all components until the mission is completely completed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
