Description

Technical Field

[0001] This invention relates to a cleaning platform for cold source interception nets in nuclear power plants, belonging to the field of interception net cleaning technology. Background Technology

[0002] In recent years, marine organism invasions, represented by shrimp and jellyfish, have become a major factor threatening the safety of water intake for coastal nuclear power plants. To combat marine organism invasions, major nuclear power plants currently adopt the method of deploying multiple interception nets at the front end of the pumping station, namely the water intake and intake channel, to intercept and filter marine organisms. The core of the front-end interception and filtration system is the use of nets. Nets can increase the interception and filtration area, guide the intercepted objects to the tail of the net, and have a certain capacity to store marine organisms.

[0003] Chinese utility model patent CN219386243U discloses a mobile cleaning system for cold-source debris interception nets. The system includes a hull, a collection frame within the hull, a lifting assembly on the hull, and a net connected to the lifting assembly. The hull has a concave portion, within which the collection frame is located to hold marine life collected by the net. The lifting assembly lifts the net to allow the marine life to fall from the net into the collection frame. This mobile cleaning system addresses the problems of high labor costs and low efficiency associated with manual cleaning through the lifting assembly, and solves the problem of limited storage capacity on manually operated vessels by designing a specialized collection frame, while also reducing operational risks for workers. However, in existing technologies, debris in the net falls into the collection frame, resulting in a high lifting height for the net. Furthermore, the large size of the net and its location in seawater make operation cumbersome. Additionally, when debris is discharged from the net, seawater drips onto the hull, impacting the hull environment.

[0004] Therefore, there is a need for a cleaning platform for the cold source interception nets of nuclear power plants to improve the convenience of net cleaning and prevent seawater from affecting the ship's environment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cleaning platform for cold source interception nets in nuclear power plants that improves the convenience of net cleaning and avoids the impact of seawater on the ship's environment.

[0006] The technical solution adopted by the present invention to solve the above problems is as follows: a cleaning platform for a cold source interception net in a nuclear power plant, comprising a hull, a lifting device provided on the hull for lifting the net bag, a suction mechanism and a collection mechanism provided on the hull, the suction mechanism for suctioning the garbage in the net bag, and the collection mechanism for collecting the garbage suctioned by the suction mechanism.

[0007] The collection mechanism includes a net bag with an opening at the top, a recessed placement groove on the left side of the hull extending to the top and bottom of the hull, the net bag being located within the placement groove, and the net bag being connected to the hull.

[0008] An extrusion assembly is provided on the left side of the hull. The extrusion assembly includes a rotating plate. The front side of the rotating plate is rotatably connected to the hull. The rear side of the rotating plate is locked to the hull by a locking member. An extrusion plate is provided on the side of the rotating plate near the hull. The extrusion plate is attached to the left side of the mesh bag. The extrusion plate is driven to move in the left and right directions by an extrusion cylinder.

[0009] The collection mechanism also includes auxiliary components, including a bellows, a fan, and a lifting pipe. The bellows is located above the mesh bag and is fixedly connected to the rotating plate. The fan is located on one side of the bellows. The lifting pipe passes vertically through the bottom of the bellows. A lifting unit is provided inside the lifting pipe bellows. The lifting unit is used to lift the lifting pipe. The bottom end of the lifting pipe is sealed. A first air hole is provided on the lifting pipe. A second air hole is provided at the bottom of the bellows.

[0010] The suction mechanism includes a suction head and a suction tube. The suction head is located on the right side of the hull. One end of the suction tube is connected to the suction head, and the other end of the suction tube is inserted from the top of the mesh bag. A suction system is connected to the suction tube.

[0011] Preferably, a sealing disc is coaxially fixedly sleeved on the lifting pipe, and the sealing disc is located inside the air box.

[0012] Preferably, the lifting unit includes a lead screw, which is arranged vertically and driven by a motor. A slider is threaded onto the lead screw and fixedly connected to the lifting tube. A guide rod is fixedly installed inside the air box and slidably connected to the lifting tube.

[0018] Preferably, multiple first air vents are provided, and the multiple first air vents are distributed circumferentially around the axis of the riser pipe.

[0019] Preferably, the lifting device has two lifting points.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] 1. By connecting the suction head to the tail of the net bag and sucking in the garbage inside the net bag, it is not necessary to lift the net bag to the top of the hull, which reduces the lifting height of the net bag, improves the convenience of operation, and thus improves the efficiency of cleaning up the garbage inside the net bag.

[0045] like Figure 1-13 As shown in the figure, a cleaning platform for a cold source interception net in a nuclear power plant in this embodiment includes a hull 1. The hull 1 is equipped with a lifting device 2 for lifting the net bag. The lifting device 2 has two lifting points, which can be easily switched when lifting the tail of the net bag to adjust the tail posture for docking. The hull 1 is equipped with a suction mechanism 3 and a collection mechanism 4. The suction mechanism 3 is used to suction the garbage in the net bag, and the collection mechanism 4 is used to collect the garbage suctioned by the suction mechanism 3.

[0046] The collecting mechanism 4 includes a net bag 41 with an opening at the top. The left side of the hull 1 is recessed to form a placement groove, which extends to the top and bottom of the hull 1. The net bag 41 is located in the placement groove and is connected to the hull 1.

[0047] The net bag 41 is provided with a connecting rope 46, which is tied to the hull 1. Both the connecting rope 46 and the net bag 41 are made of ultra-high molecular weight polyethylene, which has the characteristics of high strength and strong load-bearing capacity.

[0048] A compression assembly 42 is provided on the left side of the hull 1, and the compression assembly 42 is used to compress the mesh bag 41;

[0049] The extrusion assembly 42 includes a rotating plate 421. The front side of the rotating plate 421 is rotatably connected to the hull 1. The rear side of the rotating plate 421 is locked to the hull 1 by a locking member. An extrusion plate 422 is provided on the side of the rotating plate 421 near the hull 1. The extrusion plate 422 is attached to the left side of the mesh bag 41. The extrusion plate 422 is driven to move in the left and right directions by an extrusion cylinder 423.

[0050] A support plate 44 is provided in the placement trough. The support plate 44 is fixedly connected to the hull 1. The support plate 44 is attached to the bottom of the net bag 41. The support plate 44 is provided with multiple through holes 45, which are arranged in a matrix. The net bag 41 is supported by the support plate 44, and the through holes 45 facilitate the flow of water in the garbage into the sea.

[0051] The suction mechanism 3 transports the garbage from the top of the net bag 41 into the net bag 41, thus collecting the garbage. In practice, the net bag 41 is always above the seawater, and the moisture in the garbage inside the net bag 41 drips into the sea, preventing seawater from affecting the environment of the ship 1. When the suction mechanism 3 stops suctioning the garbage, the compression cylinder 423 drives the compression plate 422 to move to the right, causing the compression plate 422 to compress the net bag 41, thus compressing the garbage inside the net bag 41, reducing the volume of the garbage and expelling the moisture from the garbage. This not only reduces the overall volume of the garbage and increases the garbage-collecting capacity of the mesh bag 41, but also reduces the overall weight of the garbage. When the suction mechanism 3 needs to continue suctioning the garbage, the squeezing plate 422 can be moved to the left by the squeezing cylinder 423 to achieve the reset. When the garbage in the mesh bag 41 is full, the rotating plate 421 is rotated to the front of the placement slot. Then the connecting rope 46 is untied, the mesh bag 41 is taken out and replaced with a new mesh bag 41. The rotating plate 421 is rotated in the opposite direction until it is reset, and the locking device is used to lock the rotating plate 421 and the hull 1.

[0052] The collection mechanism 4 also includes an auxiliary component 43, which is used to apply air to the garbage inside the mesh bag 41;

[0053] The auxiliary component 43 includes a bellows 431, a fan 432, and a lifting pipe 433. The bellows 431 is located directly above the mesh bag 41 and is fixedly connected to the rotating plate 421. The fan 432 is located on one side of the bellows 431. The lifting pipe 433 passes vertically through the bottom of the bellows 431. A lifting unit 434 is provided inside the bellows 431 to realize the lifting and lowering of the lifting pipe 433. The bottom end of the lifting pipe 433 is sealed. The lifting pipe 433 is provided with a plurality of first air holes 435, which are circumferentially distributed around the axis of the lifting pipe 433. The bottom of the bellows 431 is provided with a plurality of second air holes 436, which are circumferentially distributed around the axis of the lifting pipe 433.

[0054] During operation, auxiliary component 43 has the following two states:

[0055] In the first state, the lifting pipe 433 is located above the mesh bag 41. The blower 432 is started and air is delivered into the air box 431. At this time, the top of the lifting pipe 433 is sealed against the top of the air box 431. The air in the air box 431 is discharged from the second air hole 436 and acts on the garbage in the mesh bag 41. Under the action of the air, the moisture on the garbage can flow downwards, and the drying speed of the garbage can also be improved.

[0056] In the second state, the waste has been squeezed and the squeezing plate 422 moves to the left to reset. The lifting unit 434 drives the lifting tube 433 to descend, so that the bottom end of the lifting tube 433 is inserted into the waste. At this time, the first air hole 435 is located inside the waste. The air in the air box 431 is transported from the top of the lifting tube 433 to the lifting tube 433. The air in the lifting tube 433 is then discharged from the first air hole 435 and acts on the inside of the waste, thereby improving the uniformity of air acting on the waste, accelerating the evaporation of residual moisture in the waste after squeezing, improving the waste drying efficiency, and further reducing the weight of the waste. Before the squeezing plate 422 squeezes the waste again, the lifting unit 434 drives the lifting tube 433 to rise to reset, so that the lifting tube 433 is above the mesh bag 41. In addition, after the last squeezing of the waste before the mesh bag 41 is removed from the placement slot, the lifting tube 433 needs to be inserted into the waste again.

[0057] The bottom end of the lifting pipe 433 is tapered, which makes it easy for the lifting pipe 433 to be inserted into the garbage;

[0058] A sealing disc 437 is coaxially fixedly sleeved on the lifting pipe 433. The sealing disc 437 is located inside the air box 431. When the lifting pipe 433 is inserted into the garbage, the sealing disc 437 blocks the second air hole 436, which facilitates increasing the amount of air discharged from the first air outlet.

[0059] The lifting unit 434 includes a lead screw 4341, which is arranged vertically and driven by a motor 4342. A slider 4343 is threaded onto the lead screw 4341. The slider 4343 is fixedly mounted on a sealing disc 437. A guide rod 4344 is vertically inserted through the sealing disc 437, and the top end of the guide rod 4344 is fixedly mounted at the top of the bellows 431.

[0060] The suction mechanism 3 includes a suction head 31 and a suction pipe 32. The suction head 31 is located on the right side of the hull 1. One end of the suction pipe 32 is connected to the suction head 31, and the other end of the suction pipe 32 is inserted from the top of the net bag 41. A suction system is connected to the suction pipe 32. The suction system consists of a diesel engine and a suction pump, which are integrated and installed on a common base. Vibration isolation measures are taken between the common base and the bottom of the hull to reduce noise. The diesel engine supplies power to the suction system and is equipped with a hydraulic clutch to control the start and stop of the suction pump, avoiding frequent starts of the diesel engine. When cleaning the garbage in the net bag, the tail of the net bag is hoisted by the lifting device 2, and the suction head 31 is connected to the tail of the net bag. Then, when the suction pump is started, the suction head 31 sucks in the garbage in the net bag and transports it to the net bag 41 through the suction pipe 32. It is not necessary to lift the net bag to the top of the hull 1, which reduces the lifting height of the net bag and improves the convenience of operation, that is, improves the efficiency of cleaning the garbage in the net bag.

[0061] In summary, by connecting the suction head 31 to the tail of the net bag and sucking in the garbage, it is not necessary to lift the net bag above the hull 1, thus reducing the lifting height of the net bag and improving the convenience of operation. This improves the efficiency of garbage cleaning in the net bag. Moreover, the garbage sucked in the net bag is directly transported to the net bag 41, and the water in the garbage in the net bag 41 flows back into the sea, thereby avoiding the impact of seawater on the environment of the hull 1. In addition, the compression of the garbage by the squeezing plate 422 reduces the volume of the garbage and removes the water inside the garbage, which not only reduces the overall volume of the garbage and improves the garbage holding capacity of the net bag 41, but also reduces the overall weight of the garbage. Furthermore, by applying air to the garbage, it is not only easier to separate water from garbage, but also improves the garbage drying efficiency and further reduces the weight of the garbage.

[0062] In addition to the above embodiments, the present invention also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
