Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.
In the description herein, references to the terms "an embodiment," "one embodiment," "some embodiments," "exemplary" and "one embodiment," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or embodiment is included in at least one embodiment or embodiment of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or implementation. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or implementations.
It should be noted that, in the related art, the manual ice breaking mode is adopted, and the ice breaking difficulty is high and the cost is high due to the fact that the water area is wide and the coverage area of the floating ice 500 is wide. When the method of increasing the diameter of the pipe pile 400 is adopted, since the coverage of the ice floe 500 is wide, when the ice floe 500 collides with the pipe pile 400, the impact force applied to the pipe pile 400 can be approximately understood as: (gravity of ice floe 500 x moving speed)/impact time, although the moving speed of ice floe 500 is slow, the coverage area is wide, the volume of ice floe 500 is large, the impact force is large, even if the pipe pile 400 is thickened, the impact resistance is limited, and the cost is high. When tubular pile 400 broke, surface of water photovoltaic power plant probably can bubble water, causes the part damage of leaking, has the electric leakage risk even, causes economic loss.
As shown in fig. 1 to 9, an embodiment of the present invention provides an anti-collision device 010, which includes an ice breaking mechanism 100 and a force applying mechanism;
the ice breaking mechanism 100 is provided with a guide structure on the periphery side in at least one direction, and the guide structure is used for contacting with the floating ice 500 and guiding the floating ice 500 in the up-down direction;
the force applying mechanism is used for applying force to the ice breaking mechanism 100 so that (the guide structure of) the ice breaking mechanism 100 can be floatingly and/or rotatably arranged at a calibrated height of a water area.
It should be noted that the force application mechanism is used for applying force to the ice breaking mechanism 100, for example, the ice breaking mechanism 100 is mounted on the column members or between the column members through the force application mechanism, and the ice breaking mechanism 100 can rotate or float to a small extent under the action of the ice floe 500 when contacting the ice floe 500, which will be described in an exemplary manner later.
In this specification, the ice breaking mechanism 100 is provided with the communicating structure 120, and the ice breaking mechanism 100 is used for being sleeved on the columnar members such as the tubular pile 400 of the photovoltaic power station on the water surface through the communicating structure 120.
It should be noted that the arrows in the figure point to the moving direction of the ice floe 500. For convenience of explanation, it is defined that the ice floe 500 moves in the front-rear direction before contacting the guide surface structure 130, and the moving direction is directed forward (i.e., positive Y-axis direction in the drawing), and it is defined that a direction perpendicular to the front-rear direction in the horizontal plane is a left-right direction, and a direction perpendicular to the horizontal plane is a vertical direction (i.e., positive Z-axis direction in the drawing, where the positive Z-axis direction is directed upward).
It should be noted that the calibration height is determined according to the height position of the ice floe 500 in the water area, and in general, the calibration height is set such that the guide surface structure 130 can contact the ice floe 500 to guide the ice floe 500 when the ice floe 500 moves to the anti-collision device 010, and it should be understood that the calibration height generally corresponds to a height range, which is not limited.
It should be noted that a guiding structure, such as the guiding surface structure 130 described later, can guide the movement of the ice floe 500, for example, the guiding surface structure 130 includes a plurality of guiding planes, when the ice floe 500 contacts with the guiding surface structure 130, the guiding action of the guiding surface structure 130 changes the moving direction of the ice floe 500, for example, the plurality of guiding planes form a polygonal frustum of a pyramid, and the distance from the guiding plane to the center line of the communicating structure 120 gradually increases from top to bottom, but is not limited thereto. The guide structure can also be formed, for example, by a plurality of obliquely arranged guide strips.
The way in which the anti-impact device 010 impacts with floating ice 500 of relatively large mass is illustrated in connection with fig. 2: the floating ice 500 with relatively large volume moves to the guide surface structure 130 of the ice breaking mechanism 100 with wind or water flow, and before the floating ice 500 moves to the guide surface structure 130, the floating ice is stressed uniformly, and is generally driven by gravity and horizontal movement. When the ice floe 500 moves forward to contact the guide surface structure 130, under the guiding action of the guide surface structure 130, the stress condition of the part of the ice floe 500 in contact with the guide surface structure 130 will change, and it is no longer simple to be driven by horizontal movement, for example, it will move up or down, the upward movement needs to overcome the gravity of the ice floe 500, and the downward movement needs to overcome the buoyancy of the ice floe 500 and the gravity of the ice breaking mechanism 100, so that the ice floe 500 is easily broken, for example, its crack extends along the X-axis direction, but it is not limited thereto, and the size of the broken ice floe 500 in the front-back direction will be small, and it is easy to break at the contact part of the guide surface structure 130 due to impact, or, the ice breaking mechanism 100 is driven to rotate relative to the pipe pile 400, so as to change the flow direction of the ice floe 500, and pass through the left and right sides of the pipe pile 400 (as shown in fig. 5).
Therefore, the utility model discloses an anti-collision device 010 sets up icebreaking mechanism 100 and forcing mechanism, but through forcing mechanism with icebreaking mechanism 100 float and/or set up in the demarcation height in waters with rotating, when icebreaking mechanism 100 is in the demarcation height, can be through the direction structure to the direction of floating ice 500 such as spigot surface structure 130, change the direction of motion of floating ice 500, floating ice 500 has the trend of upwards or downward motion, make the relatively great floating ice 500 of the size in the atress with the contact of spigot surface structure such as spigot surface structure 130 become complicated, thereby the relatively great floating ice 500 of the size will be easily cracked into the relatively less floating ice 500 of the size in the spigot structure such as spigot surface structure 130; and, when the ice 500 collides with the ice breaking mechanism 100, the ice breaking mechanism 100 may float or rotate, on one hand, the ice breaking mechanism 100 consumes kinetic energy due to the impact of the ice 500 by floating or rotating within a small range, so as to maintain the position stability of the ice breaking mechanism 100, and also improve the reliability of the ice breaking mechanism 100 to a certain extent, on the other hand, the floating or rotating of the ice breaking mechanism 100 may be adapted or changed to change the moving direction of the ice 500 in the horizontal plane, for example, change the moving direction of the ice 500, so that the ice 500 may rapidly pass through from both sides of the pipe pile 400, and the ice 500 is prevented from accumulating at the ice breaking mechanism 100, and affecting the use of the ice breaking mechanism 100. The utility model discloses an anti-collision device 010 can be used for surface of water photovoltaic power plant, protects surface of water photovoltaic power plant's tubular pile 400, reduces tubular pile 400 by the striking of ice floe 500 and cracked risk.
In an alternative embodiment, in any cross-section through the centerline of the ice breaking mechanism 100; from top to bottom, the distance from the point of the guide structure for contacting the ice floe 500 to the center line is gradually increased;
or, from top to bottom, the distance from the point of the guide structure for contacting the ice floe 500 to the center line gradually decreases;
alternatively, from top to bottom, the guide structure is adapted to have a point of contact with the ice floe 500 that is gradually increasing and then gradually decreasing in distance from the centerline.
The present invention will be described in the specification by taking the guide structure including the guide surface structure 130 and the cross-sectional shape of the guide surface structure 130 including a circle, that is, the guide surface structure 130 is a rotating surface structure surrounding the center line of the ice breaking mechanism 100 as an example, however, it should be understood that the cross-sectional shape of the guide surface structure 130 may also be a polygon (the cross-section may be understood as a section parallel to the XY plane), which may include a polygon or a circle, that is, the central angle of the guide surface structure 130 corresponding to the circumferential direction of the ice breaking mechanism 100 is not limited to 360 °, and when the guide surface structure 130 is set to a circle in the circumferential direction of the ice breaking mechanism, the projection thereof in the up-down direction may include a circle or a polygon.
In this case, the guiding surface structure 130 is a rotating surface structure, and the guiding surface structure 130 is disposed coaxially with the communicating structure 120.
As shown in fig. 2, the guide surface structure 130 illustratively includes a first tapered surface structure 131, and the upper end diameter of the first tapered surface structure 131 is smaller than the lower end diameter.
Of course, the guiding surface structure 130 may also be configured as other rotating surface structures, for example, the generatrix of the rotating surface structure may be configured as a curve, the curve may be configured as a concave form, the opening formed by the concave form faces to the upper side, which is not limited, and it is sufficient to guide the movement of the ice floe 500.
In this way, the guide surface structure 130 is configured as a rotating surface structure, and the rotating characteristic of the rotating surface structure enables the ice breaking mechanism 100 to rotate adaptively according to the floating ice 500 impacted in different directions, and can change the moving direction of the floating ice 500 better, so as to facilitate the passage of the floating ice 500 with a relatively small size; moreover, when the floating ice 500 collides with the guide surface structure 130, the contact surface is generally a small area where the generatrix of the guide surface structure 130 is located, and the contact surface is small, thereby facilitating the breaking of the floating ice 500 to some extent, for example, facilitating the left-right breaking shown in fig. 5.
In an alternative embodiment of the present invention, the diameter of the guiding surface structure 130 is gradually increased from top to bottom.
Illustratively, the guide surface structure 130 includes a first tapered surface structure 131, and an upper end diameter of the first tapered surface structure 131 is smaller than a lower end diameter.
When the ice float 500 is in contact with the guide surface structure 130, the portion of the ice float 500 near the guide surface structure 130 will be easily broken by its own weight and the reaction force of the ice breaking mechanism 100, and the shape of the first tapered surface structure 131 facilitates the broken ice float 500 to slide down into the water.
In an alternative embodiment of the present invention, the diameter of the guiding surface structure 130 is gradually reduced from top to bottom.
Illustratively, the guide surface structure 130 includes a second conical structure 132, the second conical structure 132 having an upper end diameter greater than a lower end diameter.
When the ice floe 500 contacts the guide surface structure 130, the portion of the ice floe 500 near the guide surface structure 130 will be easily broken by the buoyancy and the reaction force of the ice breaking mechanism 100 (such as the downward force caused by gravity and the force transmitted by the tube piles 400).
In an alternative embodiment of the present invention, the diameter of the guiding surface structure 130 gradually increases and then gradually decreases from top to bottom.
Illustratively, the guide surface structure 130 includes the first and second tapered surface structures 131 and 132 described above. The lower end of the first conical surface structure 131 is connected with the upper end of the second conical surface structure 132, and the diameters of the first conical surface structure and the second conical surface structure are the same, and a reinforcing structure may be arranged at the joint of the first conical surface structure and the second conical surface structure, for example, the joint of the first conical surface structure and the second conical surface structure may be slightly lower than the horizontal plane, for example, the distance from the horizontal plane is 0-30 mm, 10-20 mm, and will not be described here.
In this case, the above-described two effects can be obtained, and when the ice floe 500 has a plurality of layers, the ice floe 500 can be guided by the upper and lower portions, respectively, and at the same time, the difference in diameter between the upper and lower ends of the guide surface structure 130 can be reduced to prevent the ice breaking mechanism 100 from being excessively large in size, when the heights (i.e., the vertical dimensions) of the guide surface structures 130 are uniform and the inclination angles of the generatrices are uniform.
