Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower water delivery, in particular to a multi-directional water delivery system. Background Art

[0002] The field of water conservancy and hydropower water transmission technology often involves the dispatching of water resources. For example, in water diversion projects, sometimes it is necessary to use water pipelines to replenish water storage in reservoirs, sometimes it is necessary to use water pipelines to replenish water in natural rivers, and sometimes it is necessary to transport water in reservoirs or natural rivers to water use locations through water pipelines. Sometimes it is not necessary to replenish water in natural rivers or dispatch water in natural rivers to other locations. This requires a sophisticated design of the water transmission structure so that it can meet the different dispatching requirements in multiple directions, improve water transmission efficiency, reduce construction difficulty, and save engineering costs. However, the existing water transmission dispatching system cannot take into account the above requirements well. Utility Model Content

[0006] The cavity is set in the middle of the natural river channel, and control gates are set on both sides of the cavity and the natural river channel to cut off the water flow upstream and downstream of the river channel section where the cavity is located; when the control gate is opened, the water flow upstream and downstream of the river channel section where the cavity is located can be connected;

[0007] The water pipeline port is arranged at the bottom of the cavity, and the middle hole submerged hole gate is arranged on the cavity. When the middle hole submerged hole gate is controlled to be opened, the water flow of the water pipeline can be introduced into the natural river channel through the cavity;

[0008] Water transfer scheduling between natural rivers, water pipelines and regulating reservoirs is achieved through the combination of different opening and closing states of regulating gates, middle-hole submerged gates and connecting gates.

[0009] Preferably, the water transfer scheduling between the natural river channel, the water pipeline and the regulating reservoir is realized by combining different opening and closing states of the regulating gate, the middle hole submerged gate and the connecting gate, including:

[0010] When the middle hole submerged hole gate and connecting gate are opened and the regulating gate is closed, the water delivery path is: water delivery pipeline-water delivery pipeline outlet-cavity-middle hole submerged hole gate-river section of natural river in multi-directional water delivery system-connecting gate-regulating reservoir. The water delivery direction depends on the water head height between the water source of the water delivery pipeline and the regulating reservoir.

[0011] When the regulating gate and the middle hole submerged hole gate are opened, and the connecting gate is closed, the water delivery path is: water delivery pipeline-water delivery pipeline outlet-cavity-middle hole submerged hole gate-river section of natural river at the multi-directional water delivery system-regulating gate-downstream river section of natural river, and the water delivery direction depends on the water head height between the water source of the water delivery pipeline and the downstream river section of the natural river; or

[0012] When the middle hole submerged hole gate is closed and the regulating gate is opened, the water transfer route is to transfer water from the upstream river section along the natural river channel to the downstream river section through the multi-directional water transfer system.

[0013] Preferably, the water pipeline is also provided with a water pump for controlling the water head at the water source of the water pipeline, and the water delivery direction is controlled to deliver water to or from the water pipeline by opening and closing the water pump.

[0014] Preferably, the multi-directional water supply system further comprises an overflow port, which is arranged on the cavity and located above the mid-hole submerged hole gate to increase the position head of the water in the cavity.

[0015] Optionally, when the water pipeline also supplies water to other water users along the pipeline, the middle hole submerged gate is closed, and the water in the cavity will overflow from the overflow port, thereby raising the water head of the water pipeline and further raising the water pressure at other water users.

[0016] Furthermore, the multi-directional water supply system also includes a pollution removal device, which is arranged in the upstream direction of the cavity and is used to intercept pollutants.

[0017] Furthermore, the multi-directional water supply system also includes a water quality treatment device, a water volume metering device and a butterfly valve, which are arranged at the water supply pipeline to improve the water quality of the water transported by the water supply pipeline, control the water volume of the water transported by the water supply system and conduct pipeline maintenance.

[0043] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0044] The embodiment of the utility model provides a multi-directional water delivery system, which can be applied to similar projects such as the South-to-North Water Diversion Project as a hub linking rivers (open channels), regulating reservoirs (reservoirs) and pumping stations.

[0045] The water diversion project of this embodiment is intended to achieve the following functions: ① Using the water from the water diversion project as the water source, it can divert water to the upstream regulating reservoir (reservoir), distribute water to the water plants along the line, and also provide ecological water replenishment to the downstream river; ② Using the water reservoir (reservoir) at the end of the water diversion project as the water source, it can send water back to the starting point of the water diversion project and also provide ecological water replenishment to the downstream river.

[0046] That is, this embodiment should at least implement the following water delivery scheme:

[0047] Water transfer direction 1: Using the water from the starting point of the water transfer project as the water source to transfer water to the upstream storage tank (reservoir);

[0048] Water transfer direction 2: Using the water from the starting point of the water diversion project as the water source to carry out ecological water replenishment in the downstream river;

[0049] Water delivery direction 3: Using the upstream regulating reservoir (reservoir) at the end of the water diversion project as the water source, water is delivered in the reverse direction to the starting point of the downstream water diversion project and water users along the water transmission pipeline;

[0050] Water transfer direction 4: Use the upstream regulating reservoir (reservoir) at the end of the water diversion project as the water source to carry out ecological water replenishment for the downstream river.

[0051] The following combination Figure 1-4 This section describes how to implement the above functions, including: Figure 1 The plan layout of the core area of ​​an embodiment of a multi-directional water delivery system is shown. Figure 2 The multi-directional water transport system is shown along Figure 1 Cross-sectional view of the water flow direction through the middle hole submerged hole gate, Figure 3 The multi-directional water transport system is shown along Figure 1 A cross-sectional view of the direction of water flow through the control gate. Figure 4 The multi-directional water transport system is shown along Figure 1 The overall layout of the original natural river channel and cavity.

[0052] In this embodiment, taking into account the construction difficulty, land occupation, and economic and social benefits after completion, a reasonable location is selected in the original natural river channel to construct the core part of the multi-directional water delivery system, namely Figure 1-4 The lock chamber section and the pipe outlet section in the pipeline. Please refer to Figure 1 The lock chamber section and the pipeline outlet section include: a cavity 1, a regulating gate 2, 4, a middle hole submerged hole gate 3, and a water pipeline port 5, wherein the cavity 1 is arranged in the middle of a natural river channel 7, and regulating gates 2, 4 are arranged on both sides of the cavity 1 and the natural river channel 7 to control the regulating gates 2, 4 so that when they are opened, the water flow upstream and downstream of the river channel section where the cavity is located can be connected; the water pipeline port 5 is arranged at the bottom of the cavity, and the middle hole submerged hole gate 3 is arranged on the cavity 1, and when the middle hole submerged hole gate 3 is opened, the water flow in the water pipeline 8 can be introduced into the natural river channel 7 through the cavity 1; through the regulating gates 2, 4, the middle hole submerged hole 3, the control storage tank (see Figure 4 , Figure 1 The connecting gate 6 (not shown) for water inlet and outlet (see Figure 4 , Figure 1 By combining different opening and closing states (not shown in the figure), water transfer scheduling between natural rivers, water pipelines and storage tanks can be achieved.

[0053] It should be noted that in the implementation of the multi-directional water transfer system of the present invention, the regulating reservoir, connecting gate and upstream and downstream river sections can be kept as they are, or some necessary modifications can be made to the upstream and downstream river sections to reduce the difficulty of construction or improve the efficiency of water transfer. The implementation of the present invention does not depend on the specific topography of a specific regulating reservoir and / or upstream and downstream river sections.

[0054] Regarding the regulating gate, it should be noted that, in the present embodiment, based on the considerations of river water diversion and water delivery efficiency requirements, a regulating gate is set on each side of the cavity 1. However, the present invention is not limited to this, and technicians can set the position, quantity and design parameters of the regulating gate according to the river water runoff and water delivery requirements.

[0055] like Figure 4 As shown, the implementation and use of each component in this embodiment are as follows:

[0056] ① The regulating reservoir (reservoir) and the connecting gate 6 that controls the regulating reservoir and the river waterway are all in their current state, and the upstream and downstream river sections are partially renovated according to the needs of the water diversion project.

[0057] ② The lock chamber section and the pipeline outlet section are the core components. The lock chamber section and the pipeline outlet section are interconnected through the water pipeline port 5 set at the bottom of the cavity. The lock chamber section includes a middle hole submerged hole gate 3, an overflow port 9 and control gates 2 and 4 on both sides. The pipeline outlet section includes an underground pipeline outlet of the water pipeline (i.e., the water pipeline port 5), an above-ground open channel (i.e., a natural river channel 7) and a hoisting and closing machine room 10. Through the different forms of opening and closing combinations of the middle hole submerged hole gate 3 of the lock chamber section and the control gates 2 and 4 on both sides, a multi-directional water supply function is realized.

[0058] Figure 2 and Figure 3 Different cross-sectional views of the lock chamber section and the pipeline outlet section are shown respectively.

[0059] Combination Figure 2-4 It can be seen that when the middle hole submerged gate 3 and the connecting gate 6 are opened and the regulating gates 2 and 4 are closed at the same time, the water in the water pipeline is connected to the upstream direction of the natural river through the water pipeline port 5 and the middle hole submerged gate 3 in turn, and the water transmission scheduling between the regulating reservoir and the water pipeline can be realized. In this case, the water head at the source of the water pipeline or at any position can be further controlled so that the water flow direction between the regulating reservoir and the water pipeline meets the required water transmission scheduling direction to achieve the scheduling purpose.

[0060] That is to say, when executing the water diversion plan of water diversion direction 1 (water pipeline starting point pump station → regulating reservoir), the control gates 2 and 4 on both sides of the gate chamber section are closed to block water, and the submersible gate 3 in the middle hole of the gate chamber section and the connecting gate 6 of the regulating reservoir are opened. The incoming water enters the sewage cleaning section and the upstream river channel from the water pipeline outlet 5 through the submersible gate 3 in the middle hole of the gate chamber section, and the incoming water enters the regulating reservoir through the connecting gate 6; when executing the reverse water delivery plan of water diversion direction 3 (regulating reservoir → water pipeline starting point pump station), the control gates 2 and 4 on both sides of the gate chamber section are closed to block water, the submersible gate 3 in the middle hole of the gate chamber section and the connecting gate 6 are opened, and the water in the regulating reservoir flows through the connecting gate 6, the upstream river channel section, and the sewage cleaning section, and enters the water pipeline outlet 5 through the submersible gate 3 in the middle hole of the gate chamber section, and flows along the water pipeline 8 to the reservoir or regulating reservoir near the starting point pump station.

[0061] Combination Figure 2-4 It can also be seen that when the middle hole submerged gate 3 and the regulating gates 2 and 4 are opened and the connecting gate 6 is closed at the same time, the water in the water pipeline is connected to the upstream direction of the natural river through the water pipeline port 5 and the middle hole submerged gate 3 in sequence, and the water transmission scheduling between the water pipeline and the water use point in the downstream section of the river can be realized. In this case, the water head at the source of the water pipeline or at any position can be further controlled so that the water flow direction between the downstream section of the river and the water pipeline meets the required water transmission scheduling direction to achieve the scheduling purpose.

[0062] That is to say, when implementing the water diversion plan of water transmission direction 2 (the starting pump station of the water transmission pipeline → the downstream river channel), the control gates 2 and 4 on both sides of the gate chamber section and the middle hole submersible gate 3 are opened, and the connecting gate 6 is closed. The incoming water flows out from the water transmission pipeline outlet 5 through the middle hole submersible gate 3 of the gate chamber section, passes through the control gates 2 and 4 on both sides of the gate chamber section, enters the above-ground open channel of the pipeline outlet section, and flows from the above-ground open channel to the downstream river channel section for ecological water replenishment; when implementing the water transmission direction 4 (regulating reservoir (reservoir) → downstream river channel) plan, the control gates 2 and 4 on both sides of the gate chamber section and the connecting gate 6 are opened, and the middle hole submersible gate 3 of the gate chamber section is closed. The water in the regulating reservoir flows through the connecting gate 6, the upstream river channel section, and the sewage cleaning section, and enters the above-ground open channel of the pipeline outlet section through the control gates 2 and 4 on both sides of the gate chamber section, and flows from the above-ground open channel to the downstream river channel section for ecological water replenishment.

[0063] In this embodiment, in order to implement the water delivery plan while also supplying water to water users such as water plants along the water delivery pipeline, an overflow port 9 is designed above the cavity 1 to increase the positional head at the position of the cavity 1. The height of the overflow port 9 can be calculated based on the head required for water supply from the water plant.

[0064] When the water diversion plan in the water delivery direction 2 is implemented, and water needs to be supplied to the water plants along the water delivery pipeline in the downstream river section at the same time, it is only necessary to open the control gates 2 and 4 on both sides of the lock chamber section, close the submersible gate 3 and the connecting gate 6 in the middle hole of the lock chamber section, and the incoming water will flow out from the pipeline outlet section through the overflow port of the lock chamber section, pass through the control gates 2 and 4 on both sides of the lock chamber section, enter the ground open channel of the pipeline outlet section, and flow from the ground open channel to the downstream river section for ecological water replenishment. In other words, it is only necessary to replace the outflow from the middle hole submersible gate 3 at the interface connecting the water delivery pipeline and the natural river with the outflow from the overflow port 9 above the middle hole submersible gate 3, and increase the water head at the outlet to the water head required by the water plant water supply, so as to meet the demand for water delivery to multiple places at the same time in a low-carbon and energy-saving manner.

[0065] Similarly, when implementing the water diversion plan in water delivery direction 1, and supplying water to the water plants along the water delivery pipeline in the direction of the upstream river section at the same time, the regulating gates 2, 4 on both sides of the lock chamber section and the middle hole submersible gate 3 can be controlled to be closed, and the incoming water from the water delivery pipeline outlet 5 enters the upstream river through the overflow port 9 of the lock chamber section. The water head at the water delivery pipeline outlet 5 is the water head required for water supply to the water plant, which can also meet the needs of simultaneously delivering water to multiple locations in a low-carbon and energy-saving manner.

[0066] In addition, in order to facilitate centralized management, this embodiment also sets Figure 2 The hoist chamber 10 shown is used to accommodate and protect the hoisting and closing control mechanisms of the regulating gate and the mid-hole submerged hole gate, and to provide space for operating the hoisting and closing control mechanisms.

[0067] ③If Figure 4 , 5 As shown, in this embodiment, a trash cleaning section is also designed, and a trash rack 12 and a traffic bridge 11 are provided. On the one hand, the traffic function between the two sides of the road is realized through the traffic bridge 11. When the reverse water delivery scheme of the water delivery direction 3 is implemented, the trash rack 12 is lowered and the trash blocking function is started. The trash rack 12 can be hoisted during the rest of the water delivery time.

[0068] ④ The water delivery pipeline segment of this embodiment is also designed with a water quality treatment device to meet the quality requirements of the water delivered by the pipeline. However, the utility model is not limited thereto, and technicians can design a water quality treatment device according to actual water demand.

[0069] In this embodiment, a sodium hypochlorite dosing room and an activated carbon dosing room are provided to treat the water quality passing through the water pipeline to ensure the quality of the water transported by the pipeline. Figure 6 This is a cross-sectional view of the water pipeline and activated carbon dosing room. Figure 7 This is a cross-sectional view of the water pipeline and sodium hypochlorite dosing room.

[0070] It should be noted that Figure 6 Figure 7 The embodiments shown are all equipped with water quality control devices. Figure 6 In the embodiment, activated carbon is added. Figure 7 In the embodiment, sodium hypochlorite is added, and the technicians can choose to activate one or both of them according to the water quality problem to be treated.

[0071] It should also be noted that Figure 7 A water quality monitoring room can also be set up next to the sodium hypochlorite addition room to monitor the water quality and start adding sodium hypochlorite or activated carbon based on the monitoring results.

[0072] ⑤ In order to better monitor the water flow, the upstream river section, downstream river section and water pipeline section are equipped with Figure 7 The flow meters, butterfly valves and other pipeline ancillary facilities shown are to facilitate the stable operation and subsequent inspection and maintenance of the water pipeline section.
