Description

Technical Field

[0001] The utility model relates to a water discharge device, in particular to a reservoir ecological water discharge device combined with a fountain, which is suitable for projects with landscape tourism needs downstream of the reservoir and can make the reservoir ecological water discharge a resource and a landscape. Background Art

[0002] Dams are water-retaining structures that block high water levels in rivers to form reservoirs. To prevent water environment degradation, aquatic life extinction, and vegetation withering in the river channel downstream of the dam, and to maintain the ecological environment and integrated natural functions created by the original river runoff, reservoirs must maintain a certain ecological outflow. Due to the water level difference between the reservoir water upstream of the dam and the river channel downstream, the ecological outflow must be dissipated before entering the downstream channel to prevent harmful scour. Fountains, as ornamental water features, combine pressurized water with sound and light effects to provide a visual and auditory experience that satisfies people's pursuit of a better life. Typically, the water jets from fountains are pressurized water from a pump, which is at the same pressure level as the ecological outflow water before energy dissipation and pressure reduction. Existing ecological water discharge devices require specialized energy dissipation facilities or equipment to dissipate the water's potential energy. Without heat exchange between the water and the surrounding air, the low-temperature water is directly released into the downstream river channel. These energy dissipation facilities or equipment waste the water's potential energy, and the low-temperature water that enters the river channel directly can also damage the original ecosystem.

[0003] For reservoir projects requiring landscape integration, fountain control devices and outlet pipes replace conventional energy dissipation valves. Ecological discharge water, prior to energy dissipation and pressure reduction, serves as the fountain's pressure water. This not only avoids the need for conventional reservoir ecological flow discharge facilities or equipment, but also recycles water energy, saving the energy required to pressurize the water column during fountain operation. Typically, the lower water temperature in deep reservoirs is detrimental to downstream river ecology. By dissipating energy by throwing water into the air through fountains, the fountain accelerates heat exchange between the water and the surrounding air, helping to warm the discharged reservoir water and reducing the impact of low-temperature water on downstream river ecology. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a reservoir ecological water release device combined with a fountain, which is suitable for reservoir projects with landscape integration requirements.

[0005] The technical solution adopted by this utility model is:

[0006] A reservoir ecological water discharge device combined with a fountain includes an inlet pipe, a connecting steel pipe, a maintenance valve, a flow regulating valve, a flow meter, an outlet pipe, and a fountain pool. The fountain is used as an energy dissipation method for the ecological water discharge device, and no other special energy dissipation facilities or equipment are provided. The inlet pipe can be made of a steel pipe or other pipe other than concrete that can withstand the corresponding internal water pressure, buried in the dam body or mountain, or made by leaving holes inside the concrete dam body; the inlet pipe and the outlet pipe are connected by a connecting steel pipe, and a maintenance valve, a flow regulating valve, and a flow meter are arranged in a straight line on the connecting steel pipe; the maintenance valve is arranged at the first section of the connecting steel pipe, and is used to close to cut off the water flow when the ecological water discharge device needs to be repaired, so as to repair the equipment; the flow regulating valve is arranged after the maintenance valve, and can control the size of the downstream ecological flow according to the ecological needs of the downstream river; the flow meter is arranged after the flow regulating valve to meet regulatory requirements , it can monitor the water flow rate of the device and display the actual size of the downstream ecological flow rate; the outlet pipe is a steel pipe branched from the connecting steel pipe, the number and diameter of the branched pipes are determined according to the fountain plan, and the end of the outlet pipe is bent toward the sky, so that the water flows toward the sky to form a fountain, and the water body is thrown into the air to dissipate energy and exchange heat with the surrounding air, and the water temperature rises, thereby reducing the impact of low-temperature water on the downstream river ecology; the fountain pool is located downstream of the dam, and is a facility for collecting the falling water body of the fountain, and can be combined with the energy dissipation pool downstream of the dam; after the fountain falls through the fountain pool, it automatically flows to the river downstream of the reservoir without intercepting or consuming stored water, so that it meets the ecological flow requirements.

[0007] Furthermore, external buildings can be set up to incorporate connecting steel pipes, inspection valves, flow regulating valves, flow meters and other equipment. The external buildings need to be arranged and designed according to the actual situation of the project.

[0008] Furthermore, the reservoir ecological water release device combined with the fountain also includes a fountain control device, which is arranged on the middle and rear sections of the water outlet pipe. The fountain control device is used to adjust and change the height, shape, sound, light and other external appearances of the fountain to enrich the external expression of the fountain.

[0009] The beneficial effects of the utility model are:

[0010] 1. The reservoir ecological flow discharge involved in this utility model does not require the installation of special energy dissipation facilities or equipment. The water level difference between the reservoir water upstream of the dam and the river downstream does not need to undergo the energy dissipation and pressure reduction process before the conventional ecological flow is discharged into the river, and can directly serve as the power source for the fountain.

[0011] 2. The fountain of this utility model does not require a water pump for pressurization. Conventional fountains require a water pump to first pressurize the water, which then forms the water column that creates the fountain's landscape. The fountain of this utility model utilizes the pressure head of reservoir water as the energy source for the fountain's spray into the air, eliminating the need for a water pump. This not only reduces investment in pressurization equipment but also reduces energy consumption when operating the fountain.

[0012] 3. The utility model throws water into the air in a fountain manner, which speeds up the heat exchange between the water and the surrounding air, is conducive to the temperature rise of the downstream reservoir water, and reduces the impact of low-temperature water on the downstream river ecology.

[0013] 4. The utility model utilizes the pressure head of the reservoir water as the energy source for the fountain to spray into the air. No special power supply is required. Only the fountain control device uses an external power supply.

[0014] 5. The utility model combines the release of water from the reservoir with the fountain landscape. It does not need to set up energy dissipation facilities or equipment when the ecological flow of the conventional reservoir is discharged. On the premise of not changing the size of the ecological flow, the ecological flow discharged from the reservoir is utilized as a resource and for landscape purposes, creating a water play experience that people love. It not only meets people's pursuit of a better life, but also fully taps the tourism and economic value of the water conservancy project. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting steel pipe 2, inspection valve 3, flow regulating valve 4, and flow meter 5 are arranged in an external building 9 to facilitate daily maintenance and management. The inspection valve 3 can be closed to cut off the water flow when the ecological water release device needs to be inspected and repaired; the flow regulating valve 4 is used to control the size of the downstream ecological flow to meet the ecological needs of the downstream river; the flow meter 5 is used to monitor the water flow of the device and display the actual size of the downstream ecological flow to meet regulatory requirements. The outlet pipe 6 is branched from the connecting steel pipe 2. The number and diameter of the branched pipes are determined according to the fountain plan. The end of the outlet pipe 6 is bent towards the sky, so that the water flows towards the sky, forming a fountain. The water body is thrown into the air to dissipate energy and exchange heat with the surrounding air. The water temperature rises, thereby reducing the impact of low-temperature water on the downstream river ecology. The fountain control device 7 is located at the middle and rear end of the outlet pipe 6. It adjusts and changes the fountain's height, shape, and external appearances, such as sound and light, to enrich its visual appeal. The reservoir's ecological flow, after being ejected into the air through the outlet pipe 6, falls back into the fountain pool 8 and flows downstream into the river. The fountain pool 8 serves as a stilling basin downstream of the barrage 10.
