Description
Technical Field
The utility model relates to a cover plate device, in particular to an automatic drainage cover plate device of a water collecting well.
Background
The water collecting well of the hydroelectric power plant is often provided with a water collecting well. The collector wells are usually arranged in the lowest layer of the downstream of the hydropower plant, and the collector wells as the lowest part of the plant also play a role in collecting accidental water leakage in the plant. Present sump pit apron is ordinary grid type apron, but this apron grid is when the sump pit amount of wind is big, send on the bottom moisture, can lead to indoor humidity extremely to rise, influence equipment operational environment, accelerate the electrical equipment short circuit, mechanical equipment rusts jam etc., but the apron can not the shutoff completely again, if the shutoff completely, supply water in the hydraulic power plant technique, when unexpected situations such as pipelines burst such as domestic water take place, water can produce in a large number, if can not in time dredge, can cause very big potential safety hazard, influence the use of equipment, at this moment, need the manual work to open the sump pit, the electric leakage is likely to take place for equipment, bring the threat to staff's safety.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an automatic drainage cover plate device of a water collecting well. It can isolate water vapor of the water collecting well and realize automatic drainage.
The utility model has a technical scheme that: an automatic drainage cover plate device of a water collecting well comprises a fixing frame arranged at a well head of the water collecting well, wherein a well cover base with a reinforcing rib frame inside is arranged at the upper end of the fixing frame, and a grid type cover plate is arranged at the upper end of the reinforcing rib frame; the lower ends of two sides of the fixed frame are provided with movable plates through hinges, the joint of the two movable plates is provided with a rubber interface, the middle part of the upper end of each movable plate is provided with a spring, and the other end of each spring is connected to the lower end of the reinforcing rib frame; supporting blocks for supporting the movable plate are arranged at the lower sides of the other two sides of the fixed frame.
In the automatic drainage cover plate device for the water collecting well, the supporting block is in the shape of an isosceles triangle and is perpendicular to the lower end face of the fixing frame.
In the automatic drainage cover plate device for the water collecting well, the joint of the lower end of the fixing frame and the water collecting well is provided with the sealing gasket, and the sealing gasket is made of rubber.
In the automatic drainage cover plate device for the water collecting well, the reinforcing rib frame is square, and reinforcing ribs are arranged inside the reinforcing rib frame.
In the automatic drainage cover plate device for the water collecting well, the middle part of the well cover base is provided with the separation strips which divide the well cover base into two parts, and the number of the grid-type cover plates is two.
Compared with the prior art, the movable plate with the spring is arranged at the lower part of the fixed frame to realize upward transmission of isolated water vapor, the support block plays a supporting role for the movable plate, and the phenomenon that the support plate is staggered under the action of spring tension and the like to influence the sealing performance is prevented.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.
Example 1. An automatic drainage cover plate device of a water collecting well is formed as shown in figures 1-3 and comprises a fixing frame 1 arranged at a well head of the water collecting well, wherein a well cover base 2 with a reinforcing rib frame 5 inside is arranged at the upper end of the fixing frame 1, and a grid type cover plate 3 is arranged at the upper end of the reinforcing rib frame 5; the lower ends of two sides of the fixed frame 1 are provided with movable plates 6 through hinges 4, the joint of the two movable plates 6 is provided with a rubber interface 11, the middle part of the upper end of each movable plate 6 is provided with a spring 7, and the other end of each spring 7 is connected to the lower end of the reinforcing rib frame 5; the lower sides of the other two sides of the fixed frame 1 are provided with supporting blocks 8 for supporting the movable plate 6.
The supporting block 8 is in the shape of an isosceles triangle, and the supporting block 8 is perpendicular to the lower end face of the fixing frame 1.
The joint of the lower end of the fixed frame 1 and the water collecting well is provided with a sealing gasket 9, and the sealing gasket 9 is made of rubber.
The reinforcing rib frame 5 is square, and reinforcing ribs 10 are arranged inside the reinforcing rib frame 5.
Well lid base 2 middle part be equipped with divide well lid base 2 equally into two parts the parting bead 12, the quantity of grid type apron 3 is two.
When the utility model is installed, a fixed frame 1 is firstly installed at the mouth of a water collecting well, a sealing gasket 9 is arranged on the contact surface of the fixed frame 1 and the mouth of the water collecting well, the sealing gasket 9 can prevent water vapor in the water collecting well from escaping from the contact surface of the fixed frame 1 and the water collecting well, then a movable plate 6 is installed at the lower parts of two sides of the fixed frame 1 through hinges 4, then a spring 7 is connected at the middle part of the upper end of the movable plate 6, then supporting blocks 8 are installed at the other two sides of the fixed frame 1, the supporting blocks 8 are isosceles triangle supporting blocks, the contact surface of the supporting blocks 8 and the fixed frame 1 is the inclined plane of the supporting blocks 8, the other end of the spring 7 is connected at the lower end of a reinforcing rib frame 5, then a well lid base 2 internally provided with the reinforcing rib frame 5 is installed at the upper end of the fixed frame 1, and finally a grid type cover plate 3 is installed in the well lid base 2, when water-logging is not generated in a hydropower plant, the movable plate 6 can be jointed with two waist surfaces of the supporting blocks 8 under the action of the spring 7, the junction of two fly leafs 6 is equipped with rubber interface 11, rubber interface 11 can make two fly leafs 6 realize sealed, the unable escape of steam in the sump pit of 6 lower parts of fly leaf, can prevent that steam from causing harm to equipment, nevertheless when hydraulic power plant meets accident and leaks, the sump pit upper end can produce ponding, when water pressure is greater than spring 7 pulling force, fly leaf 6 can take place to rotate through hinge 4, thereby realize automatic drainage, avoid ponding to cause the equipment damage, threaten the emergence of staff personal safety phenomenon because of ponding leads to the electric leakage even.
