Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, and in particular to an installation structure of a temporary water retaining working gate at an inlet of a diversion tunnel. Background Art

[0002] A gate is usually set at the entrance of the diversion tunnel to control whether the upstream river water flows into the diversion tunnel. However, the current gate only has a separate water-blocking function. After the gate is opened, due to the large flow of water in the Lancang River and the large number of fish inside, some larger fish will be harmed when passing through the diversion tunnel. In addition, the water flow out of the diversion tunnel outlet is very turbulent, which can easily cause inevitable harm to larger or fragile fish.

[0003] Chinese patent number CN211498768U provides a gate combining diversion tunnel plugging and discharge, including a diversion tunnel, an arc gate installed at one end of the diversion tunnel, a plane plugging and emergency gate used in conjunction with the arc gate installed upstream of the arc gate, a gate groove for mutual cooperation with the plane plugging and emergency gate is opened on the top wall inside the diversion tunnel, a pull rod is fixedly installed on the top wall of the plane plugging and emergency gate, and the top of the pull rod is connected to an opening and closing device. In the utility model, the diversion tunnel discharge flow adopts an arc gate, and a plane plugging and emergency gate is used to block water after the arc gate is closed. The arc gate water seal device only needs to meet the rising head of the gate when the highest operating head is closed and blocked within 24 hours, and the rising head is usually lower than the final water blocking head, generally not exceeding 80m. The conventional pre-pressure water seal device can meet the water stopping requirements, and complex pressurized water stopping or eccentric hinge water stopping devices can be used without the need for complex pressurized water stopping or eccentric hinge water stopping devices, which is easy to operate and saves investment.

[0023] Example

[0024] See also Figure 1-4The utility model provides a technical solution: a temporary water retaining working gate installation structure at the inlet of a diversion tunnel, comprising a fixing structure 100 and a water retaining structure 200.

[0025] See also Figure 1-3 The fixed structure 100 includes a concrete pile 110 and a mounting member 120. The mounting member 120 includes a sliding column 121 and a sliding column 123. The sliding column 121 is slidably connected to the interior of the concrete pile 110. An expansion thread 122 is sleeved inside the sliding column 121. The expansion thread 122 is screwed into the expansion tube 113, so that the sliding column 121 can be fixed inside the concrete pile 110. The sliding column 123 is slidably connected to the interior of the concrete pile 110. An expansion wire 124 is sleeved inside the second sliding column 123, and the expansion wire 124 is screwed into the expansion tube 114, so that the second sliding column 123 can be fixed inside the concrete pile 110. A top frame 125 is fixed on the top of the second sliding column 123, and the top frame 125 plays a role in supporting the power part 210. A docking screw 126 is sleeved inside the top frame 125, and the top frame 125 can be fixed together with the first sliding column 121 and the second sliding column 123 by using multiple docking screws 126.

[0026] A water guide plate 111 is fixed on one side of the concrete pile 110, and the water guide plate 111 is also a concrete structure. Two mounting holes 112 are opened inside the concrete pile 110, and an expansion tube 113 is arranged inside the mounting hole 112. The expansion tube 113 and the expansion tube 2 114 are only slightly smaller in diameter than the mounting hole 112, and the expansion tube 2 114 is arranged inside the other mounting hole 112.

[0027] See also Figure 1-2 and Figure 4 The water retaining structure 200 includes a power member 210, a dirt-isolating member 220 and a water retaining member 230. The power member 210 is fixed on the top of the mounting member 120, the dirt-isolating member 220 is slidably connected to one side of the mounting member 120, and the water retaining member 230 is slidably connected to one side of the mounting member 120.

[0028] The power member 210 includes a motor 211, which is fixed to the top of the top frame 125. A worm 212 is fixed to the output shaft end of the motor 211, and a worm 213 is fixed to the output shaft end of the other side of the motor 211. The spiral directions of the worm 212 and the worm 213 are opposite. The dirt-isolating member 220 includes a screw 221, and the screw 221 and the screw 231 have the same spiral direction. The screw 221 is rotatably connected to the inside of the top frame 125. A worm wheel 222 is fixed to the end of the screw 221, and the worm wheel 222 is meshed with the worm 212. A material blocking frame 223 is threadedly connected to one side of the screw 221, and the material blocking frame 223 can block the water. Larger fish are intercepted, and a water hole 224 is opened on one side of the blocking frame 223. The water hole 224 facilitates water to pass through the blocking frame 223. The water retaining member 230 includes a screw rod 231, which is rotatably connected to one side of the top frame 125. A worm gear 232 is fixed to the end of the screw rod 231, and the worm gear 232 is meshed with the worm 213. A water retaining plate 233 is threadedly connected to one side of the screw rod 231. The water retaining plate 233 can block the flow of water. A sealing gasket 234 is fixed to the bottom of the water retaining plate 233. The sealing gasket 234 can fill the gap between the water retaining plate 233 and the bottom of the river channel, thereby ensuring that water does not seep out from the bottom of the water retaining plate 233.

[0029] Specifically, the working principle of the temporary water retaining working gate installation structure of the diversion tunnel inlet is as follows: when in use, firstly, the expansion tube 113 and the expansion tube 2 114 are introduced into the installation hole 112, and then the sliding column 121 and the sliding column 2 123 are placed in the grooves opened in the concrete pile 110, and then the expansion wire 122 is passed through the sliding column 121 and then screwed into the expansion tube 113, so that the expansion tube 113 expands outward, so that the expansion tube 113 drives the expansion wire 122 to be unable to be pulled out of the installation hole 112, thereby fixing the sliding column 121. Similarly, the sliding column 2 123 can also be fixed in this way, and then the material blocking frame 223 is slid into the sliding column 2 123, and the water retaining plate 233 is slid into the sliding column 121. At this time, the worker needs to lift the material blocking frame 223, and then screw rod 1 221 is screwed into the material blocking frame 223, and the screw rod 231 is screwed into the water baffle 233. By screwing in different depths, the material blocking frame 223 and the water baffle 233 are in an up-and-down situation, and then a plurality of docking screws 126 are respectively screwed into the sliding column 121 and the sliding column 2 123 to fix the top frame 125, thereby completing the installation of the gate. When it is necessary to block water, start the motor 211, so that the motor 211 drives the worm 1 212 and the worm 213 to rotate respectively, and the worm wheel 1 222 is driven to rotate by the worm 1 212, so that the screw rod 1 221 drives the material blocking frame 223 to move upward by rotation, and the worm wheel 2 232 is driven to rotate by the worm 213, so that the screw rod 231 can drive the water baffle 233 to move downward, thereby completing the water blocking process of the gate.

[0030] It should be noted that the specific model and specifications of the motor 211 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0031] The power supply and principle of the motor 211 are clear to those skilled in the art and will not be described in detail here.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
