Description

Technical Field

[0001] The utility model relates to the technical field of pumped storage power station equipment, in particular to an anti-icing device for a reservoir. Background Art

[0002] The construction and operation of pumped-storage power stations are crucial to the stable operation of the power grid. In mountainous areas, the difference in water resources is large, which is extremely beneficial to the construction of pumped-storage power stations. At present, many pumped-storage power stations have been built in the Northeast.

[0003] For pumped-storage power stations in cold areas, due to the long freezing period in winter and the high ice thickness of the reservoir, the frozen water drives the soil to expand and bulge after freezing, resulting in an uneven slope. When the ice layer is frozen together with the slope protection, an ice bending moment will be generated when the temperature rises, pushing the slope protection to move, causing slope protection damage, and seriously affecting the normal operation of the pumped-storage power station. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an anti-icing device for a reservoir to solve the problem in the prior art that the reservoir is easily damaged by ice in freezing weather.

[0005] Based on the above purpose, the utility model provides an anti-icing device for a reservoir, comprising:

[0006] The guide rail is fixed on the reservoir slope and extends along the reservoir slope to the water level line;

[0007] A guide block is slidably arranged on the guide rail, an ice-breaking cone is fixed on the guide block, and the tip of the ice-breaking cone is arranged downward;

[0008] The driving assembly is fixedly connected with the guide block to drive the guide block to move back and forth along the slope of the reservoir, and the ice-breaking cone moves synchronously with the guide block.

[0009] Further, the driving assembly includes a first driving member and a second driving member, the first driving member is used to drive the guide block to move upward along the slope of the reservoir, and the second driving member is used to control the guide block to receive or separate from the driving force of the first driving member;

[0010] When the guide block is separated from the driving force of the first driving member, it slides downward along the slope of the reservoir under the action of gravity to drive the ice-breaking cone to break the ice surface of the reservoir.

[0011] Furthermore, the first driving member includes a power motor and a rotating roller connected to the output end of the power motor, and the rotating roller and the guide block are connected by a wire rope; the power motor drives the rotating roller to rotate to reel in the wire rope to move the guide block upward along the slope of the reservoir.

[0012] Furthermore, the second driving member includes an electromagnetic clutch provided on the power motor, and the electromagnetic clutch is configured to control the start and stop state of the power motor.

[0013] Furthermore, the driving assembly also includes a fixed pulley fixed to the slope of the reservoir, and the steel wire rope is fixedly connected to the guide block via the fixed pulley.

[0014] Furthermore, a buffer spring is fixedly connected to the bottom end of the guide rail, and the guide block is abutted by the buffer spring during the downward movement.

[0015] Furthermore, a pressure sensor is provided between the ice-breaking cone and the guide block, and the pressure sensor is used to detect the ice-breaking pressure of the ice-breaking cone.

[0016] Furthermore, it also includes a control module, which is connected to the pressure sensor and the driving component respectively, and is configured to control the driving component to stop driving the guide block when the ice-breaking pressure detected by the pressure sensor is less than a preset value.

[0017] Furthermore, the ice-breaking cones have at least two spaced apart arrangements on the guide block.

[0018] Furthermore, the guide block is made of metal material.

[0019] From the above, it can be seen that the anti-icing device for reservoirs provided by the utility model utilizes a driving component to drive the displacement of the guide block, so that the ice-breaking cone on the guide block synchronously moves up and down reciprocatingly, and the action of the ice-breaking cone is used to break the ice surface of the reservoir. When the water temperature of the reservoir drops below the freezing point, the ice-breaking cone can autonomously perform the ice-breaking operation, effectively preventing the water surface of the reservoir from freezing too thick in winter, and ensuring the normal use and management of the reservoir; in addition, since the guide block is driven by the driving component to move, the automatic operation reduces the labor intensity and risk of manual de-icing and improves work efficiency.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the utility model should be the common meanings understood by people with ordinary skills in the field to which the disclosure belongs.

[0027] One or more embodiments of the present application provide an anti-icing device for a reservoir, which is described below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the anti-icing device for a reservoir described in the present application includes a guide rail 3, a guide block 6 and a driving assembly, wherein the guide rail 3 is fixed on the reservoir slope 1 and extends along the reservoir slope 1 to below the water level; the guide block 6 is slidably arranged on the guide rail 3, an icebreaker cone 4 is fixed on the guide block 6, and the tip of the icebreaker cone 4 is arranged downward, the driving assembly is fixedly connected to the guide block 6 to drive the guide block 6 to move back and forth along the reservoir slope 1, and the icebreaker cone 4 moves synchronously with the guide block 6.

[0029] It can be seen from the above description that the anti-icing device for the reservoir described in the present application utilizes a driving component to drive the guide block 6 to move, so that the ice-breaking cone 4 on the guide block 6 can synchronously move up and down reciprocatingly, and the action of the ice-breaking cone 4 can be used to break the ice surface of the reservoir. When the water temperature of the reservoir drops below the freezing point, the ice-breaking cone 4 can autonomously perform the ice-breaking operation, which effectively prevents the water surface of the reservoir from freezing too thickly in winter and ensures the normal use and management of the reservoir; in addition, since the guide block 6 is driven by the driving component to move, the automatic operation reduces the labor intensity and risk of manual de-icing and improves work efficiency.

[0030] In some embodiments, the reservoir slope 1 refers to a slope surface with a certain inclination angle. The guide rail 3 can be fixed on the reservoir slope 1 by means of expansion bolts or pins. The guide rail 3 itself is set at an inclined angle. The directional words such as "up" and "down" in the embodiments of the present application are explained with reference to the reservoir slope 1. The downward movement of the guide block 6 is a downward displacement along the slope of the guide rail 3.

[0031] In some embodiments of the present application, the guide rail 3 may be a steel rail, and the guide rail 3 is fixed to the reservoir slope 1 by expansion bolts or pins, welding, etc. The lower end of the guide rail 3 is set close to the water level line of the reservoir, thereby ensuring that when the guide block 6 slides to the lowermost end of the guide rail 3, the ice breaker cone 4 is sufficient to break the ice surface.

[0032] In some embodiments, the guide block 6 is made of a metal material, which has good rigidity and hardness and is not easily deformed by the impact of the icebreaker cone 4 .

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the driving assembly includes a first driving member and a second driving member, the first driving member is used to drive the guide block 6 to move upward along the reservoir slope 1, and the second driving member is used to control the guide block 6 to receive or disengage from the driving force of the first driving member; when the guide block 6 is separated from the driving force of the first driving member, it slides downward along the reservoir slope 1 under the action of gravity to drive the ice breaker 4 to break the ice surface of the reservoir.

[0034] like Figure 2 As shown, in some embodiments, the first driving member includes a power motor 10 and a rotating roller 9 connected to the output end of the power motor 10, and the rotating roller 9 and the guide block 6 are connected by a wire rope 7; the power motor 10 drives the rotating roller 9 to rotate to reel in the wire rope 7 to move the guide block 6 upward along the reservoir slope 1.

[0035] In addition, the second driving member includes an electromagnetic clutch 11 disposed on the power motor 10 , and the electromagnetic clutch 11 is configured to control the start and stop state of the power motor 10 .

[0036] In the above description, since the guide block 6 and the icebreaker cone 4 themselves have a certain weight, when the power motor 10 drives the rotating roller 9 to rotate, the rotating roller 9 reels in the wire rope 7 to drive the guide block 6 to move upward along the guide rail 3. When it moves to the highest point of the guide rail 3, the power motor 10 stops moving, and the electromagnetic clutch 11 separates and switches to put the power motor 10 in an unpowered state. The guide block 6 slides downward along the guide rail 3 under the action of gravity, thereby driving the icebreaker cone 4 to hit the ice surface to break the ice.

[0037] It should be noted that the electromagnetic clutch 11 described in the embodiment of the present application can be set with reference to the electromagnetic clutch 11 in the related art. The working principle of the electromagnetic clutch 11 is to control the magnetic field through the current, so as to realize the connection or separation between the active part (such as the motor shaft) and the driven part (the rotating roller 9). When the coil of the electromagnetic clutch 11 is not energized, the friction element (such as the friction plate) inside the clutch will not be pressed tightly. At this time, there is not enough contact force between the active and driven parts to transmit torque, so even if the drive motor is running, the power will not be transmitted to the load, which is equivalent to the rotating roller 9 being able to rotate freely.

[0038] In some embodiments, a limit switch or a travel switch can be set on the guide rail 3 to determine whether the guide block 6 has moved to the uppermost end of the guide rail 3. The limit switch or the travel switch is set at the upper end position of the guide rail 3. When the guide block 6 moves to the upper end of the guide rail 3, the limit switch or the travel switch detects the guide block 6, proving that the guide block 6 is at the upper end of the guide rail 3 at this time.

[0039] like Figure 1 As shown, in some embodiments, the driving assembly further comprises a fixed pulley 8 fixed to the reservoir slope 1, and the steel wire rope 7 is fixedly connected to the guide block 6 via the fixed pulley 8. Here, the provision of the fixed pulley 8 can change the traction direction of the steel wire rope 7, so that the driving assembly is arranged on a flat road surface of the reservoir, further ensuring the traction stability of the driving assembly on the guide block 6.

[0040] A pressure sensor 5 is also provided between the icebreaker cone 4 and the guide block 6 described in the present application, and the pressure sensor 5 is used to detect the ice-breaking pressure of the icebreaker cone 4. Here, when the icebreaker cone 4 breaks the ice surface, it is subjected to the reverse thrust transmitted by the ice surface. Therefore, when the icebreaker cone 4 breaks the ice, the pressure value detected by the pressure sensor 5 has a trend of increasing-decreasing; when the ice layer is too thick to be penetrated, the pressure value detected by the pressure sensor 5 has a trend of increasing-maintaining the maximum value. Only when the pressure value detected by the pressure sensor 5 is less than the preset value, it proves that the icebreaker cone 4 has completed the ice-breaking work. The setting of the preset value should be flexibly set according to different scenarios, and this embodiment will not be repeated.

[0041] Exemplarily, the larger the specifications and dimensions of the icebreaker cone 4 and the guide block 6, and the longer the guide length of the guide rail 3, the better the icebreaking effect of the icebreaker cone 4 on the ice surface, and the faster the icebreaking work can be performed. Of course, the specifications and dimensions of the icebreaker cone 4 and the guide block 6 and the guide length of the guide rail 3 need to be set according to the actual scene. The icebreaker cone 4 has at least two icebreaker cones 4 spaced apart on the guide block 6. Multiple icebreaker cones 4 break ice on the ice surface at the same time, which can effectively improve the icebreaking efficiency. The icebreaker cone 4 can use a rod-shaped cone in the related art, and the end facing the water level of the reservoir is the tip. When the guide block 6 impacts under the action of gravity, the tip of the icebreaker cone 4 digs into the ice surface to crack the ice surface.

[0042] In some embodiments, a buffer spring 2 is fixedly connected to the bottom end of the guide rail 3, and the guide block 6 is abutted by the buffer spring 2 during the downward movement. The buffer spring 2 can prevent the position-limiting guide block 6 from continuing to move downward, and prevent the guide block 6 from directly impacting the guide rail 3 during the downward displacement process, causing it to deviate from the rail. Here, illustratively, the buffer spring 2 should be set at the lowest end of the guide rail 3.

[0043] In some embodiments, the anti-icing device for a reservoir further includes a control module, which is connected to the pressure sensor 5 and the drive assembly respectively, and is configured to control the drive assembly to stop driving the guide block 6 when the ice-breaking pressure detected by the pressure sensor 5 is less than a preset value. Here, the control module can adopt a PLC control sheet in the relevant technology. Here, the control module can control the drive assembly to perform repeated ice-breaking operations. When the pressure value detected by the pressure sensor 5 is less than the preset value, it proves that the ice-breaking cone 4 has penetrated the ice surface, and the ice-breaking work can be ended at this time. However, in order to prevent the ice-breaking cone 4 from being frozen on the ice surface and to facilitate the continuation of the ice-breaking work next time, the guide block 6 can be guided to the upper end of the guide rail 3 again.

[0044] An exemplary use process of the anti-icing device for a reservoir described in this application is as follows:

[0045] During operation, the electromagnetic clutch 11 is first disengaged to put the power motor 10 in an unpowered state. The guide block 6 pulls the wire rope 7 to move under the action of gravity, and drives the rotating roller 9 to rotate under the guidance of the fixed pulley 8. The crushing cone on the guide block 6 contacts the ice surface to crush the ice surface. When the pressure sensor 5 senses the pressure, the electromagnetic clutch 11 is activated and combined to make the power motor 10 resume the rotation drive of the rotating roller 9. The power motor 10 drives the rotating roller 9 to rotate, and the rotation of the rotating roller 9 drives the wire rope 7 to reel in. Then, under the guidance of the fixed pulley 8, the wire rope 7 drives the guide block 6 to rise. When the weight block rises to the top, the electromagnetic clutch 11 is activated and disengaged again, and the guide block 6 moves down again, and then the above process is repeated until the pressure value sensed by the pressure sensor 5 is less than the preset value. After the guide block 6 is raised to the top for the last time, the power motor 10 stops working and waits for the next ice breaking process. The next ice breaking process can be delayed for 24 hours.
