Description

Technical Field

[0001] The utility model relates to the technical field of nuclear power, in particular to a pollution collection device for a pollution cleaning rake bucket of a nuclear power station. Background Art

[0002] Nuclear power plant units generate a significant amount of heat energy during operation. This heat must be removed through a coolant and delivered as steam to the turbines to generate electricity. The exhaust steam is then condensed by introducing seawater through a three-way circuit. Nuclear power plant wastewater cleaners are designed to ensure a stable flow of seawater, preventing marine life, garbage, and other contaminants from clogging the inlet pipes and triggering cooling alarms. This effectively prevents the influx of contaminants and the risk of damage to downstream equipment.

[0003] Currently, nuclear power plant cleaning machines suffer from incomplete forward movement of the cleaning blades, preventing some waste from falling into the cleaning trench. If nuclear power plant operators discover this during their inspections, they must contact service personnel to clean the waste. Service personnel typically use traditional scoop nets to hook and scrape the remaining waste. However, because traditional scoop nets are typically circular or square in shape and lack a flat structure for hooking and scraping, their efficiency and effectiveness in cleaning the remaining waste from the nuclear power plant cleaning rake bucket are limited. Furthermore, because the structure and dimensions of traditional scoop nets are not specifically designed for nuclear power plant cleaning machines, they cannot specifically clear the cleaning trenches or collect waste.

[0035] In some embodiments, the anti-slip structure includes a concave-convex structure or anti-slip lines provided on the outer surface of the handle 20 .

[0036] In some embodiments, the holding rod 20 is detachably connected to the first side portion 11. Figure 4 As shown, a connecting groove 111 is provided on the first side portion 11, and the end of the holding rod 20 is threadedly connected and fixed to the connecting groove 111. The outer periphery of the end of the holding rod 20 may be provided with an external thread. The connecting groove 111 may be provided on the side of the first side portion 11 away from the third side portion 13. The connecting groove 111 is a threaded groove to be threadedly connected to the end of the holding rod 20, and the axial end of the holding rod 20 and the connecting groove 111 can be connected by a fastener 50 (as shown in FIG. Figure 4 As shown), the fastener 50 includes but is not limited to screws or bolts, which play a dual fixing role. Of course, the holding rod 20 can also be fixedly connected to the first side portion 11, and the two can be welded together.

[0037] Preferably, the holding rod 20 is a high-density polyethylene rod. High-density polyethylene (HDPE) is a highly crystalline, non-polar thermoplastic resin generated by ethylene copolymerization. The original HDPE has a milky white appearance and is somewhat translucent in thin cross-sections. It has excellent resistance to most domestic and industrial chemicals and is resistant to corrosion and dissolution by strong oxidants (concentrated nitric acid), acids, bases, salts, and organic solvents (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance. It can be used for moisture-proof and anti-seepage purposes and is suitable for nuclear power plants near the sea. Alternatively, the holding rod 20 can be made of ultra-high molecular weight polyethylene, which is abbreviated as UHMWPE and is also known as high-strength and high-modulus polyethylene. It is an unbranched linear polyethylene with a molecular weight of more than 1.5 million. Ultra-high molecular weight polyethylene has excellent mechanical properties, excellent impact resistance, excellent wear resistance, chemical corrosion resistance, and good optical resistance. Of course, in some embodiments, the holding rod 20 may also be a stainless steel rod, which is not specifically limited here.

[0041] In some embodiments, the collection net 30 may be made of, but not limited to, a copper alloy mesh or a high-strength zinc-aluminum alloy mesh. Alternatively, the collection net 30 may be a polyethylene mesh having the following specifications: a 60-wire warp knitted mesh with a mesh size of 30 mm, a 60-wire warp knitted mesh with a mesh size of 40 mm, or a 60-wire warp knitted mesh with a mesh size of 50 mm.

[0042] In this embodiment, when there is dirt residue in the rake bucket of the nuclear power plant cleaning machine, the operator holds the holding rod 20 and uses the cleaning scraper 15 to scrape the dirt into the groove below the rake bucket of the nuclear power plant cleaning machine. When the groove below the rake bucket of the nuclear power plant cleaning machine is blocked, the cleaning scraper 15 can be extended to the bottom of the groove below the rake bucket of the nuclear power plant cleaning machine to dredge the flow channel. When the dirt in the groove below the rake bucket of the nuclear power plant cleaning machine needs to be collected, the cleaning scraper 15 can be vertically inserted downward, and the cleaning scraper 15 can be attached to the bottom of the groove below the rake bucket of the nuclear power plant cleaning machine. The collection port of the collection net bag 30 is facing the direction of water flow. Collect the waste, then the operator holds the waste collection device for the nuclear power plant cleaning rake bucket and keeps it still, and completes the collection after the water flow flushes the waste into the collection net bag 30. Then the operator holds the holding rod 20 and / or the anti-slip cover 40 and slowly lifts the waste collection device for the nuclear power plant cleaning rake bucket in the opposite direction of the water flow to send the waste to the top of the collection container. Then the operator holds the holding rod 20 or the anti-slip cover 40 and flips the collection net bag 30. At the same time, the other hand lifts the bottom of the collection net bag 30 to pour the waste collected in the collection net bag 30 into the collection container.

[0043] It can be understood that the application of the cleaning and collecting device for the nuclear power plant cleaning rake bucket makes the cleaning and collecting process of the nuclear power plant cleaning rake bucket simple and easy to operate, can fully remove the dirt remaining in the nuclear power plant cleaning machine rake bucket, quickly dredge the blocked groove, and effectively solve the problem that the traditional scoop net is difficult to fully fit the groove to collect the dirt completely.
