[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1 Reference Figures 1-2 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a splash-proof device for the flange of the water supply and drainage pipeline of a hydro generator. The first blow-off shield 101 and the second blow-off shield 102 can be quickly connected and installed by rotating the outer clamp 103.

[0027] Specifically, the blowout preventer assembly 100 includes a first blowout preventer 101, a second blowout preventer 102 disposed outside the first blowout preventer 101, and an outer clamp 103 disposed outside the second blowout preventer 102; and, The locking assembly 200 includes a transition ring 201 disposed on the end face of the second blowout shield 102, a top block 202 disposed on the outer wall of the transition ring 201, and a limiting groove 208 formed in the inner wall of the outer hoop 103; and, The shielding assembly 300 includes a baffle 301 disposed within the second blowout shield 102 and an elastic plate 302 disposed on the outer wall of the baffle 301; and, The discharge assembly 400 includes a drainage channel 401 formed on the outer wall of the second blowout preventer 102 and a baffle plate 402 disposed inside the second blowout preventer 102.

[0028] The outer wall of the conversion ring 201 is also provided with a conversion block 203, and the conversion ring 201 is rotatably connected to the second blowout shield 102.

[0029] The first blowout preventer 101 has a semi-circular groove 201a on its end face that can cooperate with the conversion ring 201. The outer wall of the first blowout preventer 101 has a baffle groove 202a that can cooperate with the top block 202 and the conversion block 203. The baffle groove 202a is connected to the semi-circular groove 201a.

[0030] A stop block 204 is movably provided in the stop groove 202a. The end of the stop block 204 near the flange is lower than the semi-circular groove 201a. A flat surface 204a is provided on the end face of the stop block 204, which can cooperate with the outer wall of the conversion block 203. An inclined surface 204b is provided on the outer wall of the stop block 204, which can cooperate with the outer wall of the conversion block 203.

[0031] The inner wall of the outer hoop 103 has a through groove 206 and a rotating groove 207. The through groove 206 is connected to the rotating groove 207, and the rotating groove 207 is connected to the limiting groove 208. Both the through groove 206 and the rotating groove 207 can be movably engaged with the top block 202.

[0032] Furthermore, Figure 1 The image shown is an exploded view of the splash-proof device, with the water supply pipeline and flange sealing sleeve in the center.

[0033] Among them, such as Figure 2 The locking assembly 200 shown is located at the annular end face of the first blowout preventer 101 and the second blowout preventer 102. The slots and holes opened in the first blowout preventer 101, the matching conversion ring 201, the top block 202 and the conversion block 203 on the outer wall of the conversion ring 201 are symmetrically arranged at the end face of the first blowout preventer 101.

[0034] Preferably, the distance between the through groove 206 and the limiting groove 208 is 90°, that is, the length of the rotating groove 207 is 1 / 4 of the circumference of the outer hoop 103, and each through groove 206, rotating groove 207 and limiting groove 208 is a group, and two groups are arranged in an array in the inner wall of the outer hoop 103, all of which can be moved and cooperate with the top block 202.

[0035] It should be noted that the rotating groove 207 is provided with a top plate connected by a compression spring, which enables the top block 202 to be lifted up under the action of the compression spring after it is engaged with the limiting groove 208, so as to prevent the top block 202 from slipping off and causing the first blowout shield 101 and the second blowout shield 102 to fall off after being connected.

[0036] Preferably, the retaining groove 202a is opened to the position one block 202 width behind the center position of the semicircular groove 201a.

[0037] When in use, when the conversion block 203 contacts the stop block 204, due to the rotational connection of the conversion ring 201 and the position of the stop block 204 being lower than the semi-circular groove 201a, the conversion block 203 contacts the inclined surface 204b first, and the stop block 204 pushes the conversion ring 201 to rotate clockwise.

[0038] In summary, the method of using this device is as follows: After inserting the first blowout preventer 101 and the second blowout preventer 102 into the water supply pipe, align the transition ring 201 with the semi-circular groove 201a, and slowly bring the two blowout preventers closer together. The inclined surface 204b pushes the transition ring 201 to rotate. At this time, the top block 202 is lifted to a position perpendicular to the pipe. Then, align the end face of the outer clamp 103 with the top block 202 through the groove 206, push the outer clamp 103 into the appropriate position, and rotate the outer clamp 103. When it is rotated to the appropriate position, the top block 202 will be pushed into the limiting groove 208 by the action of the top plate and the compression spring. Thus, the connection between the first blowout preventer 101 and the second blowout preventer 102 is realized.

[0039] Example 2 Reference Figures 3-6This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a solution to the problem that water inside the anti-splash device of the water turbine generator's water supply and drainage pipeline flange may flow out from the gaps in the anti-splash cover after splashing.

[0040] Specifically, a first connecting rod 303 is hinged inside the second blowout preventer 102, and a second connecting rod 304 is hinged outside the first connecting rod 303. The second connecting rod 304 is hinged to a baffle 301. An elastic strip 301a is provided on the end face of the baffle 301, and the elastic strip 301a is connected to the second blowout preventer 102. A trigger groove 305 is also provided on the outer wall of the second blowout preventer 102. A trigger strip 306 is provided inside the trigger groove 305. Two fixing rods 308 are provided on the end face of the trigger strip 306. A trigger block 307 is movably provided inside the two fixing rods 308. A trigger spring 309 is provided on the end face of the trigger block 307, and the trigger spring 309 is connected to the trigger strip 306. A second passage groove 307a is provided on the inner wall of the outer hoop 103. The second passage groove 307a can cooperate with the trigger block 307. A second rotation groove 307b is also provided on the inner wall of the outer hoop 103. The length of the second rotation groove 307b is less than that of the rotation groove 207.

[0041] Furthermore, all of the aforementioned shielding components 300 are also located within the first blowout preventer 101.

[0042] Preferably, the elastic plate 302 is made of elastic material and is rolled up at the upper end of the baffle 301 as shown in the figure. When the baffle 301 extends downward, the elastic plate 302 will spread out between the first dust cover 101 and the second dust cover 102.

[0043] It should be noted that, as Figure 6 The length of the second rotating groove 307b shown is shorter than that of the rotating groove 207. The length of the second rotating groove 307b plus the length of the second through groove 307a is equal to the length of the rotating groove 207. That is, when the outer hoop 103 is rotated, the trigger block 307 rotates to the limit distance, the limiting groove 208 and the top block 202 are just aligned.

[0044] Preferably, the winding direction of the elastic plate 302 inside the first blowout preventer 101 is opposite to the winding direction of the elastic plate 302 inside the second blowout preventer 102.

[0045] In summary, when the outer hoop 103 rotates, before the limiting groove 208 and the top block 202 are aligned, due to the length setting of the second rotating groove 307b, the outer hoop 103 preferentially causes the trigger block 307 to rotate along the second rotating groove 307b. After the trigger block 307 rotates, it pushes the trigger bar to push the first connecting rod 303. Figure 3As shown, the rotation is counterclockwise. At this time, the angle between the first connecting rod 303 and the push-in connecting rod 304 gradually widens, and the baffle 304 moves downward. When the baffle 304 gradually moves away from the second blowout preventer 102, the elastic bar 302 pops outward. The same is true inside the first blowout preventer 101. The two elastic plates 302 extend towards each other at the same time to close the gap between the first blowout preventer 101 and the second blowout preventer 102. At the same time, it can guide the water sprayed from the water pipe to both sides, so that the sprayed water can flow to both sides of the blowout preventer, preventing the splashed water from overflowing from the gap of the blowout preventer to the outside and corroding the external equipment.

[0046] Example 3 Reference Figures 3-6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment solves the problem that splashed water, when it remains between the blowout shields, will soak the outer wall of the water pipe and the outer wall of the flange, causing corrosion.

[0047] Specifically, the outer wall of the second blowout shield 102 is provided with a second trigger groove 404a, a second trigger block 404 is movably disposed in the second trigger groove 404a, a second trigger spring 405 is provided on the end face of the second trigger block 404, the second trigger spring 405 is connected to the baffle plate 402, and a reset spring 403 is provided on the outer wall of the baffle plate 402, the reset spring 403 is connected to the second blowout shield 102.

[0048] The inner wall of the outer hoop 103 is also provided with a third rotating groove 404b, which is connected to the through groove 206. The through groove 206 can also be movably engaged with the second trigger block 404. The third rotating groove 404b can be movably engaged with the second trigger block 404. The length of the third rotating groove 404b is less than that of the rotating groove 207.

[0049] Preferably, the above-mentioned emission components 400 are arranged in one group, which are respectively disposed in the first blowout preventer 101 and the second blowout preventer 102.

[0050] Furthermore, similar to Embodiment 2, the length of the third rotating groove 404b is less than the length of the rotating groove 207, and the sum of the lengths of the second trigger groove 404a and the third rotating groove 404b is equal to the length of the rotating groove 207. That is, when the outer hoop 103 is rotated, the second trigger block 404 rotates to the limit distance, the limiting groove 208 and the top block 202 are just aligned.

[0051] In summary, when the outer hoop 103 rotates to a certain angle, before the top block 202 aligns with the limiting groove 208, the second trigger block 404 will be triggered to rotate along the second trigger groove 404a, causing the baffle plate 402 and the second trigger block 404 to rotate synchronously, opening the drain trough 401 so that the water splashed from the drain pipe can flow out from the drain trough 401. Tools can be set below it to facilitate the centralized collection and treatment of the splashed water, so as to prevent the splashed water from corroding external tools and equipment and depositing inside the first blowout shield 101 and the second blowout shield 102, and from immersing and corroding the internal drain pipe and flange.
