Description

Technical Field

[0001] This utility model relates to the field of flood control in hydropower stations, and in particular to an emergency water-blocking device applicable to important traffic entrances of underground powerhouses in hydropower stations. Background Technology

[0002] A hydropower station consists of a hydraulic system, a mechanical system, and an electrical power generation device. It is a water conservancy project that realizes the conversion of water energy into electrical energy. The sustainability of electrical power production requires that the utilization of water energy in hydropower stations be uninterrupted. Through the construction of the reservoir system of a hydropower station, the sustainable use of water resources can be achieved. However, the power equipment and facilities in the power plant are densely packed, and the losses in the event of an unexpected water inrush are huge. Therefore, waterproofing the power plant is a key point. External water sources enter through the access tunnel, which needs to be intercepted inside the access tunnel to prevent water from entering the power plant and damaging the equipment.

[0003] In existing technologies, most emergency water-blocking solutions for sudden water inrush accidents at various access points of hydropower plant buildings rely on methods such as manually stacking sandbags to intercept water. These methods have a slow response time and are generally ineffective in preventing water inrush accidents, posing significant safety risks. Therefore, an emergency water-blocking device suitable for important access points of underground power plants in hydropower stations is proposed. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] Therefore, this utility model aims to solve the technical problem of slow response speed in existing water interception methods such as manually stacking sandbags.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an emergency water-blocking device suitable for important access tunnels in underground powerhouses of hydropower stations, comprising,

[0007] The driving component includes a protective housing, an electric telescopic rod located inside the protective housing, a hanging ring located on one side of the electric telescopic rod, and a bolt rod located inside the hanging ring;

[0008] A water-blocking component includes a water baffle plate, the back of which is equipped with a support frame assembly, which is connected to a hanging ring;

[0009] The base component includes a frame assembly, on both sides of which are mounted locking rods, and on the top of one side of each locking rod is a hinge, which is connected to a support frame assembly.

[0013] As a preferred embodiment of the emergency water-blocking device applicable to important traffic entrances of underground powerhouses in hydropower stations, the frame assembly further includes two sets of horizontal bars, with vertical bars distributed and installed between the horizontal bars.

[0014] As a preferred embodiment of the emergency water-blocking device applicable to important traffic entrances of underground powerhouses in hydropower stations, a reinforcing connecting plate is installed at the connection between the vertical rod and the horizontal rod.

[0015] As a preferred embodiment of the emergency water-blocking device applicable to important traffic entrances of underground powerhouses in hydropower stations, the water-blocking plate is equipped with locking blocks on both sides, and rubber rings are provided inside the locking blocks.

[0016] As a preferred embodiment of the emergency water-blocking device applicable to important traffic entrances of underground powerhouses in hydropower stations, the protective shell is provided with a mounting base at its bottom, and the mounting base is connected to the ground via expansion bolts.

[0017] As a preferred embodiment of the emergency water-blocking device applicable to important traffic entrances of underground powerhouses in hydropower stations, the protective shell has an opening on one side, and the side wall of the opening of the protective shell is used in conjunction with a locking block.

[0018] As a preferred embodiment of the emergency water-blocking device applicable to important traffic entrances of underground powerhouses in hydropower stations, the connecting frame includes two sets of long steel plates, with short steel plates welded between the long steel plates.

[0019] The beneficial effects of this utility model are as follows: the water-blocking component can effectively block water from entering, and can be laid flat on the ground to avoid affecting vehicle access. The electric telescopic rod can quickly pull up the water-blocking component, thereby blocking sudden water surges and buying time for personnel to use sandbags and other objects to build waterproof fortifications. At the same time, it can block small water surges and prevent small water surges from entering the factory building. Attached Figure Description

[0030] Example 2

[0031] Reference Figure 2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it provides a water-blocking component 200, including a water-blocking plate 201. The water-blocking plate 201 has locking blocks installed on both sides, which can engage with one side wall of the opening of the protective housing 101. A rubber ring is provided inside the locking block to increase sealing. The one side wall of the opening of the protective housing 101 cooperates with the locking block. A support frame assembly 202 is installed on the back of the water-blocking plate 201. 2 also includes two sets of crossbeams 202a, with a reinforcing rod 202b installed between the two sets of crossbeams 202a. Connecting frames 202c are installed at both ends of the crossbeams 202a. The connecting frame 202c includes two sets of long steel plates, with short steel plates welded between the long steel plates. The combination of long and short steel plates can effectively form an I-beam structure, thereby increasing the overall strength of the device. Holes are provided on the connecting frame 202c, and the holes are connected to bolt rods 106. Nuts are provided on the bolt rods 106 to prevent them from falling off the connecting frame 202c.

[0032] This embodiment has the following workflow: When personnel discover water flow, they can activate the electric telescopic rod 102 to retract the electric telescopic rod 102, thereby pulling up the support frame assembly 202 through the electric telescopic rod 102. At this time, the water baffle 201 faces the water flow, forming a blockage against the water flow.

[0033] Example 3

[0034] Reference Figure 1-2This is the third embodiment of the present utility model. This embodiment is based on the previous embodiment, and differs from the previous embodiment in that: this embodiment provides an emergency water-blocking device and a water collection well cover mechanism applicable to important traffic entrances of underground powerhouses of hydropower stations, combining the first and second embodiments.

[0035] The specific base component 300 includes a frame assembly 303, which also includes two sets of horizontal bars 303a. Vertical bars 303b are installed between the horizontal bars 303a. The combination of vertical bars 303b and horizontal bars 303a increases the structural strength. A reinforcing connecting plate 303c is installed at the connection between the vertical bars 303b and horizontal bars 303a. The reinforcing connecting plate 303c increases the strength of the connection and avoids the situation of incomplete welding and breakage. The frame assembly 303 has locking rods 301 installed on both sides. The locking rods 301 are used to install hinges 302. A hinge 302 is installed on the top of one side of the locking rod 301. The hinge 302 is connected to the support frame assembly 202, thereby realizing the rotational movement of the support frame assembly 202.

[0036] This embodiment has the following workflow: When in use, a groove is first dug in the ground at the traffic opening, so that the base component 300 is installed in the groove. At the same time, the drive component 100 is installed at both ends of the groove. When the electric telescopic rod 102 pulls up the support frame assembly 202, the base component 300 can support the bottom of the support frame assembly 202, so as to prevent water leakage at the bottom of the support frame assembly 202 and increase the overall stability.
