Description

Technical Field

[0001] This utility model relates to the technical field of hydropower engineering construction equipment, and in particular to a water diversion mechanism and a vertical shaft drainage device. Background Technology

[0002] When excavating water diversion shafts in areas with poor geological conditions, streams of water often seep out from both sides of the shaft walls. This seepage not only severely affects the normal excavation and support work of the shaft, but also easily damages the mechanical and electrical equipment at the bottom of the shaft. Furthermore, the seepage poses a threat to the health and safety of the workers operating underground.

[0003] Current technology typically involves collecting seepage water through lateral excavation of a collection trough in the shaft wall and discharging it via drainage pipes. However, lateral excavation requires handling more earthwork and rock, necessitating greater time, manpower, and material resources, thus increasing the construction period and costs. Furthermore, lateral excavation can potentially lead to rock mass instability issues, increasing construction risks. On the other hand, since the inner walls of pumped-storage power station shafts are often uneven, installing water troughs within the shaft can result in problems with proper fit.

[0004] Therefore, it is necessary to propose a water diversion mechanism and a vertical shaft drainage device. Utility Model Content

[0024] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0026] Reference Figure 1 This embodiment provides a water guiding mechanism, including a water guiding channel 11. One end of the water guiding channel 11 is provided with a baffle plate 12, and the end of the water guiding channel 11 away from the baffle plate 12 is provided with a water guiding strip 13. A first support member 14 is provided on the water guiding channel 11. The first support member 14 has a triangular structure and is fixedly provided at the bottom of the water guiding channel 11. Multiple first support members 14 are provided and are evenly distributed below the water guiding channel 11. The installation stability of the water guiding channel 11 can be increased by the provision of the first support member 14.

[0027] The water guide channel 11 has an arc-shaped structure; the arc-shaped structure design can improve the fit between the water guide channel 11 and the inner wall of the vertical shaft. The water guide channel 11 is made of flexible material. Specifically, the water guide channel 11, the baffle plate 12, and the water guide strip 13 are all made of silicone.

[0028] The water guide channel 11, made of flexible material, can better fit the inner wall of the shaft. During use, the water guide channel 11 is fixed to the inner wall of the shaft using tools, such as nails. When water seeps out from the inner wall of the shaft, the water guide channel 11 can guide the water for initial collection and guide the flow of the water, making it convenient to treat the seepage in the shaft. There is no need for traditional lateral excavation for drainage, which improves construction efficiency and avoids the construction hazards caused by excavating the water collection channel.

[0029] Reference Figure 1 This embodiment provides a vertical shaft drainage device, including a water intake mechanism 1 and a collection tank 2, which is used to collect the water discharged by the water intake mechanism 1; Drainage mechanism 3 is used to drain water from collection pool 2 into the shaft.

[0030] In use, the water drawn out by the water-drawing mechanism 1 is eventually collected in the collection pool 2. The collection pool 2 is made of silicone material and is fixed in the vertical shaft by tools. It should be noted that the bottom of the collection pool 2 is provided with several evenly distributed second support members 21. The second support members 21 have a triangular structure and can reinforce and support the collection pool 2. The water collected by the water guide trough 11 eventually enters the collection pool 2 for collection and is then pumped out by the drainage mechanism 3 to realize the drainage operation of the vertical shaft.

[0031] Reference Figure 1 There are several water intake mechanisms 1, and these water intake mechanisms 1 are arranged in a spiral shape.

[0032] The water guide bar 13 of the upper water guide mechanism 1 extends into the water guide groove 11 of the lower water guide mechanism 1.

[0033] The spirally distributed water guiding mechanism 1 can transfer the water guided by the water guiding channels 11 at each level and finally discharge it into the collection pool 2. Due to the spiral design, the angle covered by the water guiding channels 11 on the inner wall of the shaft is increased, thus enabling the collection and guidance of a larger range of infiltrated water. Furthermore, the sequential arrangement can form a drainage channel, guiding the water collected by each water guiding channel 11 into the collection pool 2 through the bottom water guiding bar 13, making it easier to discharge and collect the water in the water guiding channels 11.

[0034] Reference Figure 1 Several water diversion mechanisms arranged in a spiral pattern form a group. Figure 1 The water intake mechanism 1 shown constitutes a set, as referenced Figure 2 At least two sets of water diversion mechanisms 1 arranged in a circular array are provided in the same horizontal section of the vertical shaft.

[0035] By using at least two sets of water intake mechanisms 1 arranged in a circular array, the inner wall of the vertical shaft can be collected over the entire range, forming a 360-degree no-dead-angle collection of seepage water from various parts, which eventually converges into various collection pools 2.

[0036] Reference Figure 2 and Figure 3 The span angle between the starting end water diversion mechanism 1 and the ending end water diversion mechanism 1 of each group of water diversion mechanisms 1 is not less than 180 degrees. There is not only a height difference between two adjacent water diversion mechanisms 1, but also a relative angle difference. One group of water diversion mechanisms 1 can cover more than 180 degrees of the inner wall of the vertical shaft. Therefore, two groups of water diversion mechanisms 1 can form a full-range coverage without dead angles. Of course, three or four groups of water diversion mechanisms 1 can also be set in the same horizontal section. The number of water diversion mechanisms 1 that can be set depends on the span angle of the vertical shaft section occupied by the water guide channel 11. When the length of the water guide channel 11 of the water diversion mechanism 1 is short, the number of groups of water diversion mechanisms 1 in the same horizontal section can be increased. When the length of the water guide channel 11 of the water diversion mechanism 1 is long, the number of groups of water diversion mechanisms 1 can be appropriately reduced. By setting multiple groups of water diversion mechanisms 1, the load of each water guide channel 11 can be effectively reduced, the lightweighting degree can be improved, and excessive water collection can be avoided to prevent overweight. In addition, due to the problem of the humid environment inside the vertical shaft, the phenomenon of falling off and dropping in the vertical shaft can be avoided.

[0037] Reference Figure 4 A group consists of several spirally distributed water diversion mechanisms 1, and at least two groups of water diversion mechanisms 1 arranged in a linear array are provided in the same vertical section of the shaft.

[0038] As the depth of the shaft increases, by adding multiple sets of vertically arranged water diversion mechanisms 1, water collection and drainage operations can be realized in each stage of the shaft from bottom to top. Since the permeability at the bottom of the shaft is strong, the spacing between the lower ones can be reduced, thereby increasing the total number of water diversion mechanisms 1 and effectively reducing the load on each water guide channel 11.

[0039] The drainage mechanism 3 includes a water pump 31 installed in the collection tank 2, and a vertical pipe 32 installed on the water pump 31. The vertical pipe 32 is provided with a bend 33, and also includes an output pipe 34 installed on the bend 33. The water pump 31 can draw water from the collection tank 2. The vertical pipe 32 is installed vertically upward along the inner wall of the collection tank 2. The bend 33 is used to avoid obstruction by the water guide trough 11 above. The output pipe 34 is a flexible hose that extends to the top of the vertical shaft. The operation of the water pump 31 can draw water from the collection tank 2 and finally transport it to the top of the vertical shaft to form a drainage operation.

[0040] The collection pool 2 is equipped with a water level gauge; The water level gauge is used to detect the water level in collection tank 2; It also includes an automatic control system, which controls the start and stop of the water pump 31 based on the water level value detected by the water level detector.

[0041] It should be noted that the automatic control system has a first threshold K1 and a second threshold K2. The first threshold K1 is the lowest water level in the collection tank 2, and the second threshold K2 is the highest water level in the collection tank 2. When the water level in the collection tank 2 is lower than the first threshold K1, the automatic control system either does not control the water pump 31 to start or controls the water pump 31 to shut down.

[0042] When the water in the collection tank 2 is collected to a level exceeding the first threshold K1 but less than the second threshold K2, the water pump 31 will not start until the water level reaches the second threshold K2. At this point, the automatic control system will send a start command to the water pump 31, and the water pump 31 will start to discharge the water in the collection tank 2 until the water level is detected to have reached the first threshold K1 and then shut off.

[0043] The advantage of this control method is that starting the water pump 31 when the second threshold K2 is reached can prevent excessive water accumulation in the collection tank 2 from causing an overweight fall. In addition, setting the first threshold K1 allows a certain amount of water to be retained in the collection tank 2 for heat dissipation during the operation of the water pump 31. Since the output pipe 34 needs to transport water to the top of the vertical shaft and is relatively long, not starting the pump when the water level is between the first threshold K1 and the second threshold K2 allows a certain amount of water to accumulate in the collection tank 2, ensuring that a sufficient amount of water is available each time the water pump 31 operates. The water is discharged from the top of the shaft, meaning that enough water can fill the top of the output pipe 34, and the water level in the collection tank 2 is not lower than the first threshold K1. This effectively prevents the water pump 31 from stopping when the water level in the collection tank 2 reaches the first threshold K1 after the water enters the output pipe 34. Then, under the action of gravity, the water flows back into the collection tank 2. When the amount of backflow reaches the second threshold K2, the water pump 31 will start again, avoiding the problem of frequent start-up of the water pump 31, improving the service life of the water pump 31, and reducing the energy consumption of the water pump 31.

[0044] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
