DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 2 As shown, the present invention provides a hydraulic flap water retaining facility for a substation, comprising a foundation 1 and a wall 2 arranged on the upper end of the foundation 1, a protection zone 11 is arranged on the left side of the wall 2, a pit 111 is opened on the upper end surface of the foundation 1 located at the protection zone 11, a water retaining mechanism 3 is arranged inside the pit 111, a water retaining area 12 is arranged on the right side of the wall 2, the protection zone 11 and the water retaining area 12 are separated by the water retaining mechanism 3, a locking mechanism 4 is arranged inside the wall 2, and the locking mechanism 4 is used to fix the water retaining mechanism 3; so that when a flood disaster occurs, water can be blocked by the water retaining mechanism 3 to prevent water from entering the substation and damaging the power facilities inside the substation, and at the same time, the water retaining mechanism 3 is strengthened and fixed by the locking mechanism 4 to improve the reliability of the water retaining mechanism 3.

[0032] In a further embodiment, referring to Figure 3-Figure 4The water retaining mechanism 3 includes a water retaining plate 31 and a pressure plate 33. The inside of the pit 111 is rotatably connected to the water retaining plate 31 through a bearing seat. The left end below the water retaining plate 31 is rotatably connected to a rotating shaft 32. The side wall of the rotating shaft 32 is fixedly connected to the pressure plate 33 and a stopper 34. The stopper 34 is provided with two groups and is located at the front and rear sides of the pressure plate 33. A stopper groove 311 is opened inside the concave surface of the water retaining plate 31. The stopper groove 311 is set to a right-angle fan shape. The stopper 34 is located inside the stopper groove 311 and cooperates with it.

[0033] In this embodiment, the retaining groove 311 is set to be a right-angle fan-shaped, so that the retaining block 34 can only rotate 90 degrees when rotating. Therefore, when the pressure plate 33 abuts against the foundation 1 of the water retaining area 12, the pressure plate 33 is perpendicular to the water retaining plate 31. Due to the large impact force of the water flow caused by flood disasters, when the water retaining plate 31 is impacted, the water retaining plate 31 will be affected by the impact force of the water flow, so that the water retaining plate 31 tends to rotate to the right. However, the water flow will press the pressure plate 33 before impacting the water retaining plate 31, which will be able to reduce the tendency of the water retaining plate 31 to rotate to the right.

[0034] In a further embodiment, referring to Figure 4-Figure 5 A driving component 35 is arranged inside the water baffle 31. The driving component 35 is used to drive the pressure plate 33 to rotate. The driving component 35 includes a rotating shaft 351 and a driving rod 352. A first limiting groove 312 is opened inside the concave surface of the water baffle 31. The rotating shaft 351 is rotatably connected inside the water baffle 31. The front and rear side walls of the rotating shaft 351 are fixedly connected to the driving rod 352 and the top block 354. The driving rod 352 is located inside the first limiting groove 312. A second limiting groove 314 is opened on the left end surface of the water baffle 31, and the top block 354 is located inside the second limiting groove 314.

[0035] In this embodiment, since the end of the driving rod 352 and the top block 354 away from the rotating shaft 351 is located on the left side of the rotating shaft 351, the driving rod 352 will rotate around the rotating shaft 351 and drive the top block 354 to rotate. The rotating top block 354 can push the pressure plate 33 to rotate around the rotating shaft 32, thereby providing power for the pressure plate 33 to separate from the concave surface of the water retaining plate 31.

[0036] In a further embodiment, referring to Figure 2-Figure 9 The right end of the driving rod 352 is fixedly connected to a spring paddle 353, and the end of the spring paddle 353 away from the driving rod 352 is fixedly connected to the inner wall of the first limiting groove 312. A through hole 313 is opened on the left end surface of the water baffle 31, and the through hole 313 passes through the first limiting groove 312. The right end of the wall 2 is fixedly connected to a push rod 21, and the right end surface of the push rod 21 passes through the through hole 313 and abuts against the left end surface of the driving rod 352.

[0037] In this embodiment, when the water baffle plate 31 abuts against the wall 2, the top rod 21 will pass through the through hole 313 and abut against the driving rod 352. As the water baffle plate 31 continues to rotate, the top rod 21 pushes the driving rod 352, and the driving rod 352 compresses the spring paddle 353. When the water baffle plate 31 rotates in the opposite direction, the top rod 21 cancels the abutment against the driving rod 352, so that the driving rod 352 pushes the driving rod 352 to return to its initial state when the spring paddle 353 recovers its deformation.

[0038] In a further embodiment, referring to Figure 8 A first sealing strip 315 is fixedly connected to the left end of the water baffle 31. Two groups of the first sealing strip 315 are provided and are located on the front and rear sides of the water baffle 31. The left end of the first sealing strip 315 abuts against the wall 2. A second sealing strip 316 is fixedly connected to the lower end of the water baffle 31. Both front and rear ends of the second sealing strip 316 are fixedly connected to the lower end of the first sealing strip 315. The second sealing strip 316 abuts against the upper end surface of the foundation 1.

[0039] In this embodiment, by setting the first sealing strip 315 and the second sealing strip 316, the first sealing strip 315 and the second sealing strip 316 can activate the sealing effect during the water blocking process of the water retaining plate 31, thereby preventing water from seeping out from the gap between the water retaining plate 31 and the wall 2 during the water blocking process, thereby affecting the water blocking effect.

[0040] In a further embodiment, referring to Figure 1-Figure 2 The inside of the pit 111 is rotatably connected with a hydraulic telescopic rod 5 through a bearing seat, and the output end of the hydraulic telescopic rod 5 is rotatably connected to the right end of the water retaining plate 31 through the bearing seat.

[0041] In this embodiment, the hydraulic telescopic rod 5 is started to drive the output end of the hydraulic telescopic rod 5 to extend, thereby pushing the water baffle 31 in the pit 111, thereby achieving the effect of providing power for the rotation of the water baffle 31; because the pit 111 can accommodate the water baffle 31, and at the same time, the foundation 1 of the protection zone 11 is set at an angle with the horizontal plane, when the water baffle 31 is accommodated, the pressure plate 33 on the water baffle 31 forms an angle less than 90 degrees with the foundation 1 of the protection zone 11, and under the action of gravity, the pressure plate 33 will automatically rotate and be accommodated in the concave surface of the water baffle 31, thereby facilitating the passage of pedestrians and vehicles.

[0042] In a further embodiment, referring to Figure 6-Figure 7The locking mechanism 4 includes a mounting block 41 and a protrusion 42. A slide groove 22 is provided inside the wall 2 at the rear side of the foundation 1. The mounting block 41 is slidably connected inside the slide groove 22. A second spring 44 is fixedly connected to the rear end of the mounting block 41. One end of the second spring 44 away from the mounting block 41 is fixedly connected to the inner wall of the slide groove 22. A receiving groove 411 is provided on the lower end surface of the front side of the mounting block 41. The protrusion 42 is slidably connected inside the receiving groove 411. A third limiting groove 412 is provided on the inner wall of the receiving groove 411. The front and rear ends of the protrusion 42 are fixedly connected. A limit block 421 is located inside the third limit groove 412 and is slidably connected thereto. A first spring 43 is fixedly connected to the rear end of the protrusion 42. An end of the first spring 43 away from the protrusion 42 is fixedly connected to the inner wall of the receiving groove 411. A groove 413 is provided on the rear end surface of the mounting block 41. A tooth 414 is fixedly connected to the inner wall of the groove 413. A transmission rod 45 is rotatably connected inside the wall 2. The transmission rod 45 passes through the inside of the slide groove 22. A gear 46 is fixedly connected to the lower end of the transmission rod 45. The gear 46 and the tooth 414 are meshed with each other.

[0043] In this embodiment, during the water blocking process, the pressure plate 33 rotates by gravity and abuts against the surface of the protrusion 42. At this time, the pressure plate 33 continues to rotate, and the protrusion 42 moves backward, squeezing the first spring 43 at the same time. When the pressure plate 33 moves to the lower end of the protrusion 42, the protrusion 42 recovers its deformation on the first spring 43 and pushes the protrusion 42 to move forward, so that the lower end surface of the protrusion 42 abuts against the upper end surface of the pressure plate 33, thereby achieving the effect of fixing the pressure plate 33 and enhancing the stability of the water retaining plate 31. When the pressure plate 33 is to be stored, the transmission rod 45 must be rotated first to drive the gear 46 to rotate. Since the gear 46 is meshed with the teeth 414, the mounting block 41 is driven to move backward. The mounting block 41 moving backward drives the protrusion 42 to move backward, so that the protrusion 42 and the pressure plate 33 are no longer in contact. The pressure plate 33 can rotate without the obstruction of the protrusion 42. When the pressure plate 33 moves to the top of the protrusion 42, the transmission rod 45 is released, and the second spring 44 automatically drives the mounting block 41 to move to the initial position when it recovers its deformation.

[0044] The working principle of the present invention is as follows: before the arrival of a flood disaster, the hydraulic telescopic rod 5 is started to drive the water retaining plate 31 to move out of the pit 111 and abut against the right end surface of the wall 2, thereby achieving a water retaining effect and preventing the hydraulic telescopic rod 5 from being soaked in water, thereby extending the service life of the hydraulic telescopic rod 5; in the process of the water retaining plate 31 abutting against the wall 2, the top rod 21 will penetrate the through hole 313 and abut against the driving rod 352, and as the water retaining plate 31 continues to rotate, the top rod 21 pushes the driving rod 352, and since the end of the driving rod 352 and the top block 354 away from the rotating shaft 351 is located on the left side of the rotating shaft 351, the driving rod 352 will rotate around the rotating shaft 351 as the axis and drive the top block 354 to rotate, and the rotating top block 354 can push the pressure plate 33 to rotate around the rotating shaft 32 as the axis, and at this time the pressure plate 33 is separated from the water retaining plate 3 1 concave surface, so that the pressure plate 33 forms an acute angle with the horizontal plane, and under the action of gravity, the pressure plate 33 is automatically driven to rotate. Since the retaining groove 311 is set to a right-angle fan shape, the stopper 34 can only rotate 90 degrees, so that the pressure plate 33 abuts against the ground. When the pressure plate 33 rotates by gravity, it will abut against the surface on the protrusion 42. At this time, the pressure plate 33 continues to rotate, and the protrusion 42 will move backward and squeeze the first spring 43 at the same time. When the pressure plate 33 moves to the lower end of the protrusion 42, the protrusion 42 recovers its deformation on the first spring 43 and pushes the protrusion 42 to move forward, so that the lower end surface of the protrusion 42 abuts against the upper end surface of the pressure plate 33. Therefore, when a flood disaster comes, the pressure plate 33 is pressed by water to limit the rotation of the water retaining plate 31, so that the water retaining plate 31 can withstand the impact of water waves, thereby improving the water retaining effect;

[0045] When the flood disaster is over, it is necessary to rotate the transmission rod 45 to drive the gear 46 to rotate. Since the gear 46 and the teeth 414 are meshed with each other, the mounting block 41 is driven to move backward. The mounting block 41 moving backward drives the protrusion 42 to move backward, so that the protrusion 42 and the pressure plate 33 are no longer in contact. At this time, the hydraulic telescopic rod 5 is started to drive the output shaft of the hydraulic telescopic rod 5 to shrink, thereby driving the water baffle 31 to rotate. The rotation of the water baffle 31 drives the pressure plate 33 to rotate. The pressure plate 33 can rotate without the obstruction of the protrusion 42. When the pressure plate 33 moves to the top of the protrusion 42, the transmission rod 45 is released, and the second spring 44 recovers the deformation and automatically drives the mounting block 41 to move to the initial position. When the water baffle 31 moves to the inside of the pit 111, since the pressure plate 33 forms an angle less than 90 degrees with the foundation 1 of the protection zone 11, under the action of gravity, the pressure plate 33 will automatically rotate and be stored in the concave surface on the water baffle 31, so as to facilitate the passage of pedestrians and vehicles.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
