[0002] After long-term use, a large number of marine organisms will grow on the inner wall of the submarine water intake tunnel. Excessive marine organisms will reduce the water intake area of the water intake tunnel, which will have a significant impact on the water intake capacity of the tunnel. The marine organisms in the submarine water intake tunnel are huge and there are many debris (such as steel bars, stones, etc.). After the tunnel is cleaned, a large number of marine organisms accumulate on the curved surface and middle plane of the inner wall of the tunnel.

[0003] Due to the limitation of tunnel structure, it is difficult to completely clean the marine organisms on the curved surface of the inner wall of the tunnel, and there are often marine organism residues; at the same time, the bottom of the tunnel is slippery, the passage is narrow, and the passage of large equipment is restricted. The tunnel should also minimize local stress to avoid internal cracks. At the same time, because the device is driving in the tunnel, the ground conditions are complicated, and the road conditions when entering the site are complicated, so there are certain adaptability requirements for the non-working state of the device and the chassis deviation in the working state, so the device needs to have a certain degree of independence and autonomous position correction function.

[0050] As Figure 2 shown, the collection module 2 is connected to the front end 10 of the moving module 1. The collection module 2 includes a first wing component 21 and a foldable second wing component 22. The first wing component 21 and the second wing component 22 are respectively connected to opposite sides of the moving module 1; the first wing component 21 and the second wing component 22 can open and close towards the front end 10 of the moving module 1, and are received in the front end 10 of the moving module 1 in the folded state. Specifically, the first wing component 21 and the second wing component 22 are respectively hinged to the moving module 1, and the first wing component 21 and the second wing component 22 can open and close at a certain angle with an axis parallel to the perpendicular line, and incline forward at a certain angle with the tunnel cross-section in the working state. The bottom wall 100 of the tunnel includes a bottom plane 101 and arc surfaces 102 connected to both sides of the bottom plane 101. The bottom edges of the first wing component 21 and the second wing component 22 can respectively be adapted to the arc surfaces 102 on the bottom wall 100 of the submarine intake tunnel to clean the marine organisms on the bottom wall 100 of the tunnel.

[0051] Driven by the moving module 1, the collection module 2 moves horizontally along the axis of the tunnel, gathering the marine organisms located in the tunnel towards the conveying module 3. The conveying module 3 is adapted to the bottom plane 101 of the tunnel, and conveys the marine organisms to the side opposite to the advancing direction of the moving module 1, that is, the marine organisms gather at the front end 10 of the moving module 1 and enter the moving module 1 under the transportation of the conveying module 3.

The whole conveying module 3 can swing around the chain rake driving shaft system 33. In some embodiments, further, a limit shaft head 312 is arranged on the side plate 311, and a floating limiting frame 36 is arranged above the conveying module 3 corresponding to the limit shaft head 312 to limit the swinging amplitude of the conveying frame 31. The two limit shaft heads on the conveying frame are supported by two limit seats 35 fixed on the moving module 1, and the floating limiting frame 36 is installed on the limit seats 35. At this time, the swinging amplitude of the conveying module 3 is limited within a certain angle. When the feeding at the head of the whole conveying module 3 is excessive, it can adapt to materials of different heights. The head can float appropriately to reduce material blockage. The chain rake driving shaft system 33 of the conveying module 3 can rotate forward and backward. The reverse rotation is started when there is material blockage, and the blockage state can be effectively relieved.

[0054] As Figure 2 and Figure 4 shown, in some embodiments, the first wing component 21 and the second wing component 22 are connected to the moving module 1 through a driving component 23. The driving component 23 includes a first wing driving member 231 connected to the first wing component 21 and a second wing driving member 232 connected to the second wing component 22.

Specifically, the fixed wing 221 and the second hinge bracket 224 can be hinged by a pin shaft.

[0058] Refer to Figure 8, a pair of pin holes are provided on the fixed wing 221 and the folding wing 222 respectively, and are installed in the corresponding pin holes through the pivot pin shaft 2236 to achieve hinge connection. The first bracket 2233 can be an I-shaped bracket, and the second bracket 2234 can be a curved bracket. The first bracket 2233, the second bracket 2234, the first connecting member 2231, and the second connecting member 2232 are jointly connected to form a link structure. Under the action of the second side wing driving member 232, the folding wing 222 can rotate around the axis perpendicular to the pivot pin shaft 2236, the side surface disengages from the end surface of the fixed wing 221, rotates to the side away from the moving module 1, and can be folded and accommodated at the front end 10 of the moving module 1. In some embodiments, the folding wing 222 can be opened and closed relative to the fixed wing 221, and the opening and closing angle is 0~180°. The second side wing assembly 22 can be opened and closed to the front end 10 of the moving module 1. That is to say, during the opening and closing process, an included angle is formed between the folding wing 222 and the fixed wing 221, and the included angle can be 0~180°. The second side wing assembly 22 can be folded forward by up to 180°, greatly reducing the width of the collection module 2 in the non-working state.

Under the control of the hydraulic system, the hydraulic system can control the operation of the first wing drive 231 and the second wing drive 232, so that the first wing assembly 21 and the second wing assembly 22 can achieve controllable opening and closing actions.

[0063] When the device finishes running and needs to be transported, after the mobile module 1 is lifted, the second wing drive 232 on the second wing assembly 22 pulls backward, driving the movement of the drive connection assembly 223, and rotates the folding wing 222 around the axis of the rotation center pin 2236 for folding. After folding, the first wing assembly 21 and the second wing assembly 22 swing inward at a certain angle under the thrust of the first wing drive 231 and the second wing drive 232. At this time, the collection module 2 is folded, and the overall external dimension becomes smaller, and it can smoothly pass through narrow areas and be transported.

At this time, the motor can drive the third screw conveyor 253 to rotate, and at the same time drive the second screw conveyor 252 coupled to the third screw conveyor 253 to rotate. The screw blade structures on the second screw conveyor 252 and the third screw conveyor 253 can push the material they contact to move to one side when rotating.

[0071] Such as Figure 3As shown, in some embodiments, the axes of the screw conveyors can be arranged obliquely with respect to the bottom surface. Two of each of the first screw conveyor 251, the second screw conveyor 252, and the third screw conveyor 253 can be provided respectively. Therefore, they can be divided into two sets of screw conveyor assemblies 25 arranged side by side vertically. Each set of screw conveyor assemblies 25 includes a first screw conveyor 251, a second screw conveyor 252, and a third screw conveyor 253. Among the two sets of screw conveyor assemblies 25 arranged side by side vertically, the set of screw conveyor assemblies 25 on the upper side is longer, and its tail is placed on the upper side of the conveying module 3, and the marine organisms can be pushed onto the top surface of the conveying module 3. The tail of the set of screw conveyor assemblies 25 on the lower side is arranged outside the conveying module 3. It should be noted that the end of the screw conveyor assembly 25 connected to the screw drive motor is the front part, and the tail refers to the side opposite to the front part. Specifically, the two first screw conveyors 251 can be arranged side by side vertically, and moreover, the first screw conveyor 251 located above can be longer than the first screw conveyor 251 located below, and the one located above extends to the upper side of the conveying module 3. The second screw conveyor 252 and the third screw conveyor 253 can be arranged with reference to the same principle and will not be repeated here. The overhanging structure on the upper side of the fixed wing 221 can enable the extended part of the longer second screw conveyor 252 to extend out of the side plate for installation.

[0072] As Figure 9 shown, the second screw conveyor 252 and the third screw conveyor 253 are connected in transmission through an automatic coupling assembly 5. Among them, the automatic coupling assembly 5 includes two half couplings 51, two bearings 52, and two elastic members 53, and the elastic member 53 can be a compression spring.

[0073] Referring together Figure 11 to, the second screw conveyor 252 and the third screw conveyor 253 are respectively connected to the two half couplings 51. In some embodiments, the two half couplings 51 can be slidably connected and installed on the shaft heads of the second screw conveyor 252 and the third screw conveyor 253. The two bearings 52 are respectively installed on the second screw conveyor 252 and the third screw conveyor 253. Specifically, a first bearing fixing cylinder and a second bearing fixing cylinder are installed on the connecting side shaft heads of the second screw conveyor 252 and the third screw conveyor 253. The first bearing fixing cylinder and the second bearing fixing cylinder are respectively fixed on two sets of suspension plates 2221, and the two bearings 52 are respectively installed on the sides of the first bearing fixing cylinder and the second bearing fixing cylinder opposite to the suspension plates 2221. The other ends of the second screw conveyor 252 and the third screw conveyor 253 can also be installed on the suspension plates 2221 equipped with bearings 52 or inserted into the screw drive motor. In this way, the second screw conveyor 252 and the third screw conveyor 253 can rotate freely.

[0074] Two compression springs are respectively sleeved on the shaft heads of the second screw conveyor 252 and the third screw conveyor 253. One end of one compression spring abuts against the shoulder of the bearing 52 on the second screw conveyor 252, and the other end of this compression spring abuts against the end face of the half coupling 51 on the second screw conveyor 252. Similarly, one end of the other compression spring abuts against the shoulder of the bearing 52 on the third screw conveyor 253, and the other end of this compression spring abuts against the end face of the half coupling 51 on the third screw conveyor 253.

[0075] Refer together Figure 12 and Figure 13 , the half coupling 51 is installed on the shaft heads of the second screw conveyor 252 and the third screw conveyor 253 through structural limits and can slide a certain distance. As Figure 12 and Figure 13 shown, the half coupling 51 is a special structure of a toothed coupling. Its teeth have two size structures, and the grooves also have two matching size structures. Each half coupling 51 includes protruding teeth arranged at intervals, and the protruding teeth include at least two first protruding teeth 511 and at least one second protruding tooth 512. The cross-sectional area of the second protruding tooth 512 is larger than that of the first protruding tooth 511. In this embodiment, the number of the first protruding teeth 511 is two, and the number of the second protruding teeth 512 is one. A groove is formed between two adjacent protruding teeth, and the structure of the groove corresponds to and matches the structure of the protruding teeth, so that the two half couplings 51 can be engaged with each other to achieve shaft coupling. The groove includes a first groove 513 and a second groove 514. The shape of the first groove 513 is adapted to the first protruding tooth 511, and the shape of the second groove 514 is adapted to the second protruding tooth 512.

[0076] After rotating into place, the protruding teeth can be embedded for connection. When the half couplings 51 are separated and then matched again, when the angles of the two half couplings 51 are inconsistent, the protruding teeth cannot be embedded, and the two half couplings 51 located on the second screw conveyor 252 and the third screw conveyor 253 push each other away, and the compression springs are compressed. When the half coupling 51 at the drive shaft starts to rotate and rotates to the engagement angle, the half coupling 51 is engaged under the push of the compression spring, and the shaft coupling is completed. It can be automatically separated and engaged without manual intervention to achieve self-positioning. The structures of the first wing component 21 and the second wing component 22 are substantially the same. The difference is that there is no split in the middle of the helix of the first wing component 21, which is an integral structure, and its blades are reversely rotated.

[0077] The conveying module 3 is floatingly connected to the moving module 1 and extends forward to the front end 10 of the moving module 1. The frame of the conveying module 3 is semi-floatingly installed and can rotate by a certain angle around the axis of the installed driving shaft, which can adapt to the material conditions at different heights and reduce the occurrence of blockage. The conveying module 3 can be arranged at the middle position of the whole device. The output end of the conveying module 3 is arranged corresponding to the inlet end of the moving module 1, and is used for peeling off the marine organisms on the bottom wall 100 of the tunnel and conveying the marine organisms conveyed by the collection module 2 to the receiving cavity 60 of the moving module 1 at the rear end together.

[0078] When the nuclear power tunnel marine organism collection device is working, after the device travels to the tunnel center line, it is lowered as a whole to closely adhere to the tunnel bottom surface, and at the same time, the conveying module 3 is adjusted horizontally. At this time, the device is at the working height. The second wing assembly 22 is opened under the pulling of the second wing driving member 232, and the supporting wheel 24 at the tail of the second wing assembly 22 closely adheres to the tunnel wall. The bottom of the first wing assembly 21 and the bottom of the second wing assembly 22 closely adhere to the arc surface 102 of the tunnel wall and have a certain pressing force. Similarly, the first wing assembly 21 is opened under the pulling of the first wing driving member 231, and the first wing driving member 231 always maintains a constant rear pulling force during operation.

[0079] Each rotating part is started. The device pushes and gathers marine organisms under the push of the moving module 1. The scraping plate assembly 4 scrapes the tunnel wall to clean the marine organism materials adhered to the tunnel wall. After the materials are piled up to a certain height or the height of the materials themselves is relatively high, the materials are pushed to the middle under the action of the lateral component force generated by the forward inclination of the wings and the thrust of the double helix. The upper-layer materials are pushed to the top of the chain rake 34 of the conveying module 3 and are conveyed backward from the bottom through leakage and the drive of the chain rake 34 and enter the moving module 1 for the next process link.

[0080] The present invention can simply and efficiently clean and peel off the marine organisms remaining on the inner arc wall of the tunnel; it has good automatic centering performance, can simplify the operation, and achieve high-purity cleaning of the tunnel. It has good self-adaptability and ensures a high degree of fit between the collection module 2 and the inner wall of the tunnel. It has good adaptability to the amount of marine organism materials, can adapt to large changes in the amount of materials, and is not easy to cause blockage. Moreover, it has good passability in narrow sections. The collection module 2 can be folded, the overall external dimensions become smaller, and the transfer is convenient. The collection device has a simple structure, convenient maintenance, and strong conveying capacity.

[0081] It can be understood that the above embodiments only represent the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, the above technical features can be freely combined, and several modifications and improvements can also be made, which all fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention shall fall within the scope covered by the claims of the present invention.
