It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0029] It is noted that when an element is referred to as being "connected" to another element, it can be directly connected to the other element, or connected to the other element through intervening elements. "Connected" in the following embodiments, if the connected circuit, module, unit, etc. have the transmission of electrical signal or data between each other, should be understood as "electrically connected", "communicatively connected" and the like.

[0030] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. It will be further understood that the terms "comprises", "comprising", "includes" and / or "including", or the like, when used in this specification, specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0031] It should be noted that the water discharge structure a is formed with a non-pressure emptying tunnel a1 extending in the front-rear direction, and the upstream side of the front side of the non-pressure emptying tunnel a1. The non-pressure emptying tunnel a1 is used to reduce the water level of the reservoir and reduce the reservoir capacity. The non-pressure emptying tunnel a1 is provided with a maintenance valve b1 and a working gate b2 near the front side thereof. The water discharge structure a includes a stilling basin a2, a tunnel open channel section a3 and a downstream channel a4 located behind the maintenance valve b1 and the working gate b2.

[0032] Please refer to Figure 1 and Figure 2 The water intake structure of the reservoir non-pressure emptying tunnel provided by the utility model comprises a water intake pipe 1 arranged in the non-pressure emptying tunnel a1 extending in the front-rear direction. The water intake pipe 1 extends in the front-rear direction and is divided into a control section pipe 11, an energy dissipation section pipe 12 and a main water supply pipe 13 connected in sequence. The water inlet 111 of the control section pipe 11 is arranged between the maintenance gate b1 and the working gate b2. The energy dissipation section pipe 12 is arranged in the stilling basin a2 behind the working gate b2. The main water supply pipe 13 is arranged in the tunnel open channel section a4, and a gate valve 2 is arranged at the water outlet 131 of the main water supply pipe 13 and connected to the downstream water supply pipe. The energy dissipation section pipe 12 and the main water supply pipe 13 are arranged along the side edge of the lower wall of the non-pressure emptying tunnel a1.

[0033] The water inlet 111 of the water intake pipe 1 is arranged between the working gate b2 and the maintenance gate b1, and is used for water in the reservoir to enter the water intake pipe 1. The water outlet 131 of the water intake pipe 1 is communicated with the downstream water supply pipe, so as to complete the water intake of the reservoir. The gate valve 2 is arranged at the water outlet 131 to adjust the water discharge flow rate at the water outlet 131. The energy dissipation section pipe 12 and the main water supply pipe 13 are arranged in the non-pressure emptying tunnel a1 and along the side edge of the lower wall of the non-pressure emptying tunnel a1, so as to reduce the impact of the non-pressure emptying tunnel a1 on the energy dissipation section pipe 12 and the main water supply pipe 13 during flood discharge. In the case of water intake, the flood discharge of the non-pressure emptying tunnel a1 is not affected. In this way, the existing non-pressure emptying tunnel a1 of the reservoir is used, and separate water intake facilities do not need to be newly built, so as to reduce the land occupation and save the engineering investment. The gate valve 2 is used to control the water discharge flow rate, and the operation is simple and safe.

[0034] Specifically, refer to Figures 1 to 3The control section pipe 11 is arranged in the inside of the lower part of the spillway structure a forming the non-pressure air release hole a1, and at least partially in the lower side of the working gate b2, and the water inlet 111 of the control section pipe 11 is arranged on the hole wall of the non-pressure air release hole a1. In the embodiment, the control section pipe 11 is arranged upstream of the working gate b2, downstream of the maintenance gate b1, through the part of the spillway structure a corresponding to the lower side of the working gate b2, and in the case of normal water taking, the diameter of the control section pipe 11 is arranged as small as possible to reduce the influence on the civil structure of the spillway structure a corresponding to the working gate b2.

[0035] More specifically, in the embodiment, the arrangement of the control section pipe 11 needs to be analyzed according to the stress of the working gate b2, so that the control section pipe 11 is arranged in the area of the spillway structure a corresponding to the lower side of the working gate b2 with the minimum concrete stress to reduce the influence on the civil structure of the spillway structure a corresponding to the working gate b2. In addition, the existing steel bars of the working gate b2 are not damaged as much as possible during construction.

[0036] In the embodiment, referring to Figure 2 and Figure 5 , the main water supply pipe 13 is further connected with an exhaust pipe 3 extending in the up-down direction, and an automatic exhaust valve 4 is arranged on the exhaust pipe 3 to exhaust the gas in the water taking pipe 1.

[0037] Further, in the embodiment, referring to Figure 2 and Figure 5 , the exhaust pipe 3 is arranged in close contact with the inner wall of the stilling basin a2, and the exhaust port 31 of the exhaust pipe 3 is arranged at the highest position of the inner wall of the non-pressure air release hole a1 corresponding to the stilling basin a2; and the automatic exhaust valve 4 is arranged on the exhaust port 31. The exhaust pipe 3 is fixed by being in close contact with the inner wall of the non-pressure air release hole a1 corresponding to the stilling basin a2, and the exhaust port 31 is arranged at the highest position of the stilling basin a2 to ensure that the automatic exhaust valve 4 can continuously exhaust and avoid being submerged.

[0038] In the embodiment, a trash screen 5 is arranged on the water inlet 111 to intercept larger particles of silt.

[0039] In order to exhaust the silt in the water taking pipe 1, the water taking structure of the reservoir non-pressure air release hole comprises silt exhaust wells 6 and gate valve wells 7 arranged in the front-rear direction, and the silt exhaust wells 6 and the gate valve wells 7 are arranged at the downstream channel a4 of the rear side of the tunnel open channel end; the main water supply pipe 13 is further provided with a silt exhaust valve 8 arranged on the front side of the gate valve 2, and the silt exhaust valve 8 is arranged in the silt exhaust well 6, and the gate valve 2 is arranged in the gate valve well 7.

[0040] In the embodiment, when the sediment in the water taking pipe 1 accumulates too much, the sediment valve 8 is opened and the gate valve 2 is closed, the water flow drives the sediment in the water taking pipe 1 to flow out of the outlet of the sediment valve 8, so that the sediment in the water taking pipe 1 can be washed out and the water taking pipe 1 is cleaned. When water is needed, the sediment valve 8 is closed and the gate valve 2 is opened, and the water flow flows from the water taking pipe 1 to the downstream water supply pipe. The sediment well 6 and the gate valve well 7 protect the corresponding sediment valve 8 and gate valve 2, and facilitate maintenance.

[0041] It should be noted that when the sediment valve 8 is closed, the water taking pipe 1 is connected, and when the sediment valve 8 is opened, the water taking pipe 1 is blocked, and the water flow flows out of the outlet of the sediment valve 8.

[0042] In order to reduce the impact on the energy dissipation section pipe 12 and the main water supply pipe 13 during flood discharge, in the embodiment, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , a protective layer 9 is arranged around the outer periphery of the energy dissipation section pipe 12 and the main water supply pipe 13. The protective layer 9 is a planted concrete layer, which wraps the entire outer periphery of the energy dissipation section pipe 12 and the main water supply pipe 13, reducing the risk of damage to the energy dissipation section pipe 12 and the main water supply pipe 13. In addition, under the condition of meeting the water supply capacity, the pipe diameter of the energy dissipation section pipe 12 and the main water supply pipe 13 is set as small as possible.

[0043] The above only describes the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
