Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering and emergency rescue equipment, and in particular to a reservoir leak plugging and diversion device. Background Technology

[0002] When reservoir dams or river embankments are in operation for a long time or encounter severe floods, they often experience seepage, piping, and other dangerous situations due to reasons such as foundation seepage, material aging, or biological damage. If not dealt with in time, these situations can easily develop into catastrophic accidents such as dam or embankment collapse, seriously threatening the safety of people's lives and property downstream.

[0003] Currently, the main methods for dealing with such emergencies include manually throwing sandbags and boulders, or using steel-wood-earth-stone composite dams and driving anti-seepage piles. These traditional methods have the problem of low efficiency. Specifically, sealing with sandbags and boulders requires a lot of manpower, and the speed of transportation and throwing is slow. In the face of emergency emergencies, the efficiency is insufficient. Therefore, we propose a reservoir leakage plugging and diversion device. Utility Model Content

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-4 A reservoir leakage plugging and diversion device is provided. The reservoir leakage plugging and diversion device includes a central diversion pipe 1, which is a hollow rigid pipe. One end of the central diversion pipe 1 is a conical diversion inlet 101, and the other end of the central diversion pipe 1 has an external thread 102 on its outer surface. The sealing and anchoring mechanism includes a guide cover 2 sleeved and installed on the outer surface of the central drainage pipe 1. A memory foam sealing body 3 is installed on the outer side of the guide cover 2. A pressure ring 4 is sleeved on the outer surface of the central drainage pipe 1. The pressure ring 4 is pressure-connected to the inner side of the guide cover 2. A drive ring 6 is threadedly connected to the external thread 102. A connecting rod 5 arranged in a circumferential array is fixedly installed between the drive ring 6 and the pressure ring 4. An anchoring spike 7 is detachably installed on the drive ring 6. The drainage control valve 8 is threadedly installed at the end of the central drainage pipe 1 away from the conical drainage inlet 101. In application, the rigid central drainage pipe 1 and the conical drainage inlet 101 work together to achieve rapid drainage and ulcer pressure dispersion. At the same time, the memory foam seal 3 in the sealing and anchoring mechanism is linked with the drive ring 6 to form a three-dimensional sealing layer after expansion. Combined with the threaded connection of the drainage control valve 8, it is convenient for graded flow control.

[0022] Reference Figure 1 and Figure 2 The guide cover 2 is funnel-shaped, and the large-diameter end of the guide cover 2 faces the drive ring 6. In application, the funnel-shaped guide cover 2 can guide the device to accurately fit into the rupture, prevent the memory foam seal 3 from shifting, and enhance the water flow guiding effect.

[0023] Reference Figure 3 and Figure 4The memory foam seal 3 is made of polyurethane polymer water-absorbing and expanding material, and the outside of the memory foam seal 3 is covered with an anti-erosion rubber layer 301. In application, the water absorption and expansion rate of polyurethane memory foam can reach 300%-500%, and it can expand to 5 times its original volume within 3 seconds to fill the gap. Combined with the anti-erosion rubber layer 301, it can quickly fill cracks and resist high-speed water flow erosion.

[0024] Reference Figure 3 and Figure 4 The inner diameter of the pressure ring 4 is matched with the outer diameter of the central drainage tube 1. In application, the precise matching design between the pressure ring 4 and the central drainage tube 1 ensures that the pressure is evenly transmitted to the memory foam seal 3, avoiding leakage caused by local stress concentration.

[0025] Reference Figure 1 and Figure 3 One end of the drive ring 6 has an integrally formed drive rod 601 arranged in a circular array on its outer surface. In application, the circular array of drive rods 601 provides multiple force application points, enabling the operator to achieve single-handed rotation adjustment under complex working conditions and improve operating efficiency.

[0026] Reference Figure 1 and Figure 3 The other end of the drive ring 6 has an integrally formed fixing ear 602 arranged in a circular array, and the fixing ear 602 has an elongated fixing hole. The anchoring bar 7 is installed on the fixing ear 602 through the elongated fixing hole. In application, the elongated fixing hole provides the anchoring bar 7 with an angle adjustment range of ±15° to adapt to the anchoring requirements of irregular rupture morphology.

[0027] Reference Figures 1-3 The top of the anchoring bar 7 has an integrally formed limiting block, and the bottom of the anchoring bar 7 has a sharp structure. In application, the combination design of the limiting block and the sharp bottom makes the anchoring depth controllable, thereby improving the pull-out resistance.

[0028] Reference Figures 1-3 The flow control valve 8 is one of the butterfly valve, ball valve or gate valve. In application, the multi-type valve is compatible design to meet the flow regulation requirements from 0.5m³ / s (butterfly valve) to 5m³ / s (gate valve).

[0029] The working principle of this utility model is as follows: Device installation: First, align the conical drainage inlet 101 with the center of the breach, then rotate the drive rod 601 clockwise, use the connecting rod 5 to push the pressure ring 4 and the guide cover 2, and compress the memory foam sealing body 3, finally insert the anchoring spike 7 through the fixing ear 602, and hammer the anchoring spike 7 so that the anchoring spike 7 is inserted into the dam body and fixed. Drainage control: First, open the drainage control valve 8 to 50% of its opening. After the compressed memory foam seal 3 has fully expanded, open it to the full extent. Then, adjust the drainage control valve 8 according to the water level difference. Dismantling and recycling: First, when pulling out the anchoring spike 7, grout is injected to fill the anchoring hole simultaneously. Then, the drive rod 601 is rotated counterclockwise to release the pressure of the memory foam seal 3. Finally, the dismantled memory foam seal 3 can be dried and reused (life ≥ 5 times).

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
