Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage in power plants, in particular to a water supply and drainage isolation device in a power plant. Background Art

[0002] After the power plant completes the power generation work, the combustion products and wastewater will be discharged into the wastewater pool through the water supply and drainage pipe. At the same time, the other end of the wastewater pool is connected to a drainage pipe, which continuously discharges the wastewater in the wastewater pool into the wastewater reaction tank for purification, so as to prepare for later repeated recycling. After searching, the Chinese patent publication number CN210917696U discloses a power plant water supply and drainage isolation device, including a pipeline body and a wastewater pool on the right. The upper end of the pipeline body is provided with a bracket, and a cylinder is installed on the bracket. The piston rod of the cylinder is fixedly connected with an isolation plate, and the upper end of the pipeline body is provided with a square guide hole. The isolation plate can block the pipeline body in time, improve the flexible use of the isolation plate, and improve the wear resistance and sealing of the isolation plate during isolation.

[0003] Although the above technical solution realizes the automatic lifting and lowering of the isolation plate and improves the wear resistance and sealing of the isolation plate during isolation, in actual use, when the isolation plate is closed, the wastewater will cause impact on the isolation plate. The above technical solution does not have a buffer structure, which will cause impact damage to the isolation plate in the long run, thereby affecting the service life. In addition, no filtering structure is provided. After the combustion products are mixed with wastewater and discharged into the wastewater pool, it will not only cause the drain pipe to be blocked, further reducing the service life, but also require subsequent filtering operations, which increases the processing steps and reduces work efficiency. Summary of the invention

[0008] A sealing gasket is fixedly connected to the outer surface of the support frame and the side close to the sewage pipe, and the sealing gasket matches the end surface of the sewage pipe;

[0009] The self-cleaning filter mechanism comprises openings symmetrically opened on both sides of the outer surface of the rectangular frame, a filter screen is fixedly connected between the two openings, a motor is fixedly installed on one side of the outer surface of the rectangular frame, the output shaft of the motor is fixedly connected to a screw rod rotatably connected to the inside of the rectangular frame, the outer surface of the screw rod is threadedly connected to a moving plate, and the bottom end of the moving plate is fixedly connected to a scraper matched with the filter screen;

[0012] In the above structure of the utility model, the setting of the isolation mechanism and the buffer mechanism enables that when the isolation mechanism is closed, the water in the sewage pipe impacts the buffer plate, and can be buffered under the action of the buffer spring, thereby reducing the impact of the water flow on the isolation mechanism, and a slope is provided on one side of the buffer plate, which can guide the water flow, thereby achieving the effect of unloading, further reducing the impact force on the isolation mechanism, and improving the service life of the isolation mechanism. The setting of the self-cleaning filter mechanism enables the power plant wastewater to enter the rectangular frame through the sewage pipe and be filtered by the filter net, thereby eliminating the subsequent filtering procedures and improving work efficiency. The rotation of the motor drives the screw rod to rotate, and the thread can drive the moving plate and the scraper to move back and forth to remove impurities, which can avoid clogging of the drain pipe and further improve the service life. The trigger mechanism can trigger the switch to control the closure of the isolation mechanism when the wastewater pool is full, so that the sewage pipe is automatically closed when the wastewater pool is full. The trigger is rapid and accurate, further improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] like Figures 1 to 3As shown, a water supply and drainage isolation device for a power plant includes a wastewater tank 1, a drainage pipe 7 is fixedly installed through one side of the bottom of the wastewater tank 1, a rectangular frame 2 is fixedly installed on one side of the upper surface of the wastewater tank 1, a sewage pipe 3 is fixedly installed through one side of the outer surface of the rectangular frame 2, an isolation mechanism 4 that cooperates with the sewage pipe 3 is rotatably connected to the inner wall of the rectangular frame 2, and the isolation mechanism 4 includes a side plate 41, one side of the outer surface of the side plate 41 is fixedly connected to a support frame 42 by bolts, one side of the outer surface of the side plate 41 is fixedly connected to a plurality of buffer springs 43, the other end of the buffer spring 43 is fixedly connected to a buffer plate 44 that is slidably connected to the inner wall of the support frame 42, and one side of the buffer plate 44 is provided with an inclined surface.

[0019] A connecting ear 45 is fixedly connected to the top of the support frame 42 , and the connecting ear 45 is rotatably connected to the inner wall of the rectangular frame 2 . A hydraulic rod 46 is rotatably connected between the inner wall of the rectangular frame 2 and one side of the outer surface of the side plate 41 .

[0020] A sealing gasket 47 is fixedly connected to the outer surface of the support frame 42 and the side close to the sewage pipe 3 , and the sealing gasket 47 matches with the end surface of the sewage pipe 3 .

[0021] When in use, the operation of the hydraulic rod 46 can drive the side plate 41 and the support frame 42 to rotate, thereby realizing the closure of the sewage pipe 3. When closing, the water in the sewage pipe 3 hits the buffer plate 44, which can be buffered under the action of the buffer spring 43, thereby reducing the impact of the water flow on the isolation mechanism 4, and a slope is provided on one side of the buffer plate 44 to guide the water flow, thereby achieving the effect of unloading force, further reducing the impact force on the isolation mechanism 4, and can increase the service life of the isolation mechanism 4.

[0022] like Figure 1 and Figure 2 As shown, a self-cleaning filter mechanism 5 matched with the sewage pipe 3 is installed inside the rectangular frame 2, and the self-cleaning filter mechanism 5 includes openings 51 symmetrically opened on both sides of the outer surface of the rectangular frame 2, and a filter screen 52 is fixedly connected between the two openings 51. A motor 53 is fixedly installed on one side of the outer surface of the rectangular frame 2, and the output shaft of the motor 53 is fixedly connected to a screw rod 54 rotatably connected inside the rectangular frame 2. The outer surface of the screw rod 54 is threadedly connected to a moving plate 55, and the bottom end of the moving plate 55 is fixedly connected to a scraper 56 matched with the filter screen 52.

[0023] The waste water from the power plant enters the rectangular frame 2 through the sewage pipe 3 and is filtered by the filter screen 52, thereby eliminating the subsequent filtering process and improving work efficiency. At the same time, it avoids the blockage of the drain pipe 7. The motor 53 rotates to drive the screw rod 54 to rotate, and the thread can drive the moving plate 55 and the scraper 56 to move back and forth to remove impurities.

[0024] like Figure 1 and Figure 4As shown, a trigger mechanism 6 cooperating with the isolation mechanism 4 is fixedly installed on the upper surface of the wastewater pool 1 and on one side away from the rectangular frame 2.

The bottom end of the vertical rod 65 is fixedly connected to a floating ball 66. The first trigger switch 62 and the second trigger switch 63 are both electrically connected to the hydraulic rod 46 through wires.

[0025] The working process of the trigger mechanism is as follows: when the water level in the wastewater tank 1 rises, it will drive the float 66 and the trigger rod 64 to rise. When it rises to the point where the trigger rod 64 contacts the first trigger switch 62, the water level is at the highest point. The first trigger switch 62 will control the hydraulic rod 46 to operate, thereby driving the isolation mechanism 4 to rotate and close the sewage pipe 3. When the drain pipe 7 drains the sewage in the wastewater tank 1, the float 66 and the trigger rod 64 will drop. When the trigger rod 64 contacts the second trigger switch 63, the second trigger switch 63 will control the hydraulic rod 46 to operate, thereby driving the isolation mechanism 4 to rotate and open the sewage pipe 3, thereby achieving the effect of automatic isolation.
