Technical Field

[0001] The invention relates to the technical field of civil engineering of hydropower plants, and in particular to a waterproof protection device for civil engineering of hydropower plants and a construction method thereof. Background Art

[0002] With the continuous development and improvement of the civil engineering of hydropower plants, waterproof protection as an important part of it has also received more and more attention and attention. In the civil engineering of hydropower plants, the importance of waterproof protection has become increasingly prominent, especially in the civil engineering of hydropower plants, where pressure pipes are important pipeline systems for transporting water, steam or other fluids. In order to ensure the safe operation of pressure pipes and avoid water leakage, waterproof protection is essential. With the advancement of science and technology and the continuous improvement of engineering technology, the waterproof protection of pressure pipes in the civil engineering of hydropower plants has been more comprehensively and effectively applied. In the past, the waterproof protection of pressure pipes mainly relied on traditional waterproof materials and construction methods, such as waterproof coatings and waterproof membranes. Today, with the introduction of new waterproof technologies and the development of intelligent waterproof systems, the waterproof protection of pressure pipes has become more efficient and reliable. By introducing new waterproof materials, waterproof coatings and waterproof membranes, the waterproof performance and durability of pipelines can be effectively improved and their service life can be extended.

[0008] A motor is connected to the outer wall of one side of the fixed plate by bolts, the output end of the motor is connected to the driving end of the rotating stretching mechanism, a spraying mechanism is arranged at the moving end of the rotating stretching mechanism, and a material guide component is arranged between the circumference of one side of the inner ring and the spraying mechanism.

[0009] Preferably: the rotary stretching mechanism includes a rotary toothed disc, a rotary shaft, a gear, a rotary rod, a fixed seat, an inner ring 2, a guide rod 1 and a guide rod 2, and the rotary toothed disc is rotatably connected to one side circumference of the fixed ring, the inner ring 2 is connected to the inner circumference of the rotary toothed disc by a thread, the fixed seat is fixedly connected to one side circumference of the inner ring 2, and the rotary rod is inserted into the interior of the fixed seat by a bearing.

[0010] Furthermore, the rotating shaft is connected to the end of the rotating rod through threads, the gear is connected to the circumferential outer wall of the rotating shaft through threads, the rotating gear plate and the rotating shaft are meshed with each other, and one end of the guide rod is connected to the end of the rotating rod through threads.

[0011] Based on the above scheme: one end of the guide rod 2 is rotatably connected to one end of the guide rod 1, and the other end of the guide rod 1 is rotatably connected to the circumferential outer wall of the spraying mechanism, and the output end of the motor is connected to one end of the rotating shaft through a thread.

[0012] A better solution among the above solutions is that the material guiding assembly includes an external pipe, a valve, a connecting pipe and a bellows, and the connecting pipe is connected to one side of the circumference of the inner ring through threads.

[0013] As a further solution of the present invention: the bellows is connected to one end of the connecting pipe by threading, the external pipe is connected to the other end of the connecting pipe by threading, and the valve is sleeved on one side of the circumference of the external pipe.

[0014] At the same time, the spraying mechanism includes a guide ring, a material guide ring and a nozzle, and the circumferential sides of the guide ring are rotatably connected to one end of four guide rods through guide shafts, and the material guide ring is fixedly connected to the inner circumference of the guide ring.

[0015] As a preferred embodiment of the present invention, the nozzle is connected to the inner circumference of the guide ring at equal distances through threads, and the inner wall of the guide ring is connected to one end of the bellows through a guide tube.

[0016] At the same time, universal wheels are fixedly connected to both sides of the bottom of the base, and push handles are fixedly connected to both sides of the back side of the fixing ring.

[0017] A waterproof protection construction method for civil construction of a hydropower plant comprises the following steps:

[0020] S3: Waterproof coating construction: spray the waterproof coating on the surface of the pressure pipe:

[0021] S4: Joint treatment: seal the joints of the pressure pipe waterproof coating;

[0022] S5: Waterproof coating detection: Perform a water pressure test by injecting water into the pressure pipe to ensure that there is no leakage on the pipe surface.

[0023] The beneficial effects of the present invention are:

[0024] 1. A waterproof protection device for civil engineering of a hydropower plant, when working, a starting motor drives the gear on the circumference of the rotating shaft located on one side of the bottom of the rotating gear disk to rotate, and the rotating gear drives the rotating gear disk to rotate. At this time, the rotating gear disk rotates in a circle on one side of the fixed ring, and the rotating rotating gear disk drives the other three gears located on the tooth convexities of the rotating gear disk to rotate synchronously, and the four synchronously rotating gears drive the rotating rods on their respective sides to rotate, and the rotating rotating rod drives the guide rod 1 at its end to rotate, and the rotating guide rod 1 pulls the guide rod 2 at one end to swing, thereby realizing the horizontal reciprocating motion of the spraying mechanism located at the center of the rotating gear disk. At this time, starting the spraying mechanism expands the area of ​​waterproof spraying on the surface of the pressure pipe by the spraying mechanism. At the same time, the overall device is displaced with the aid of a pusher, which can effectively adapt to the requirements of waterproof protection spraying on the surfaces of pressure pipes of different lengths, thereby improving practicality.

[0025] 2. A waterproof protection device for civil engineering of a hydropower plant. When the rotating guide rod 1 pulls the guide rod 2 at one end thereof to swing, the guide ring is pulled by it to perform horizontal displacement. During this period, by connecting the external pipe to the spraying equipment, the waterproof coating enters the corrugated pipe through the external pipe, is injected into the guide ring through the corrugated pipe, and is sprayed out through multiple nozzles on the inner circumference of the guide ring. A uniform waterproof coating is formed on the surface of the pressure pipe located on the inner circumference of the guide ring, which effectively plays a role in waterproofing the surface of the pressure pipe.

[0026] 3. A waterproof protection device for civil engineering of a hydropower plant. When the waterproof coating enters the inner cavity of the guide ring through the bellows, it is filtered by the filter ring located in the inner cavity of the guide ring and guided by the hemispherical convexities arranged at equal intervals, thereby ensuring that the coating in the guide ring will not be blocked or unevenly transported, which is conducive to forming a uniform waterproof coating on the surface of the pressure pipe.
