Description

Technical Field

[0001] The utility model relates to the technical field of control devices, in particular to a pumped storage unit safety control device. Background Art

[0002] A pumped storage unit is a type of energy storage unit that combines both water pump and turbine working modes. It is mainly used in the fields of peak load shifting, frequency and phase regulation, and emergency backup in power systems. In order to stably control the energy storage unit during operation, controllers and other devices are used to control the inflow and outflow of water according to the water level.

[0003] After searching, the patent number CN210289996U discloses a pumped storage unit stability control device. The control device has a reasonable structural design. It monitors the water level in real time through a water level monitor, and cooperates with the electric generator to provide power and electricity to the turbine and water pump for water pressure control, thereby avoiding damage to the turbine and water pump caused by excessive water pressure, reducing costs and improving efficiency.

[0004] Since some water level monitors monitor the water level by being placed in water, impurities in the water easily adhere to the outside of the probe of the water level meter, resulting in the probe being unable to effectively receive and transmit pressure data, etc., and thus unable to accurately detect the water level. At the same time, when the water level meter is inserted into the water, it cannot be effectively cleaned, reducing the control effect. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a pumped storage unit safety control device.

[0025] The utility model provides Figure 1-2 A pumped storage unit safety control device shown in the figure comprises a unit 1 and a controller 2 arranged on the top of the unit 1, a main water inlet pipe 3 and a main water outlet pipe 4 are arranged inside the unit 1, a horizontal plate 5 is fixedly arranged outside the unit 1, a winding wheel 6 is fixedly arranged on the top of the horizontal plate 5, a transmission cable 7 is fixedly wound inside the winding wheel 6, and a water level gauge 8 is fixedly arranged at the bottom of the transmission cable 7;

[0026] A limiting cylinder 9 is fixedly provided at the bottom of the transverse plate 5, a ring 10 is fixedly provided at the bottom of the limiting cylinder 9, a rotating tube 11 is rotatably provided on the inner wall of the ring 10, the rotating tube 11 is rotatably connected to the inner wall of the ring 10 through a rotating bearing, a cleaning cotton 12 is provided inside the rotating tube 11, and the cross-section of the cleaning cotton 12 is annular, Velcro 20 is fixedly provided on the outer side of the cleaning cotton 12 and the inner wall of the rotating tube 11, and the two Velcro 20 are bonded together.

[0027] During the operation of the energy storage unit, the water level inside the lower reservoir is monitored by the water level gauge 8. When the water level is high, the unit starts and the water inside the lower reservoir is pumped into the upper reservoir through the water inlet pipe 3. When the water level is low, the water in the upper reservoir flows into the lower waders for replenishment to complete a power generation operation. After the water level gauge 8 has been used for a long time, the operator drives the winding wheel 6 to wind the transmission cable 7. At this time, the water level gauge 8 is pulled into the cleaning cotton 12. During the upward movement of the water level gauge 8, the cleaning cotton 12 rubs against the outside of the water level gauge 8 to clean the impurities on the outside of the water level gauge 8, thereby ensuring that the surface of the water level gauge 8 is clean, thereby improving the accuracy of water level monitoring. Under the action of the Velcro 20, the cleaning cotton 12 can be replaced regularly to improve the cleaning effect.

[0028] In order to be able to fully wipe and clean the outside of the water level gauge 8, Figure 1-2As shown, a connecting plate 13 is fixedly disposed on the upper end of the outer wall of the transmission cable 7, a rack 14 is fixedly disposed on the bottom of the connecting plate 13, a telescopic rod 19 is fixedly disposed on the top of the connecting plate 13, and the top of the telescopic rod 19 is fixedly connected to the cross plate 5. A cross bar 15 is rotatably disposed on the outer wall of the collar 10, a circular gear 16 is fixedly disposed on the end of the cross bar 15, and the circular gear 16 is matched with the rack 14. A bevel gear 17 is fixedly sleeved on the rod wall of the cross bar 15, and a bevel gear ring 18 is fixedly sleeved on the outer side of the rotating tube 11, and the bevel gear 17 is matched with the bevel gear ring 18.

[0029] When the transmission cable 7 is wound, supported by the telescopic rod 19, the connecting plate 13 drives the rack 14 to move upward. At this time, through the meshing of the rack 14 and the circular gear 16, the cross bar 15 can drive the bevel gear 17 to rotate. Under the meshing of the bevel gear 17 and the bevel gear ring 18, the rotating tube 11 can rotate under the support of the collar 10, so that the cleaning cotton 20 can rotate around the water level gauge 8, and the impurities on the outside of the water level gauge 8 can be completely cleaned, ensuring that the water level gauge 8 can be inserted into the water for accurate and effective monitoring, and ensuring that the pumped storage unit can be stably controlled.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
