All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The underwater rotary cleaning assembly, the underwater cleaning device and the underwater cleaning equipment provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 1 to 6, the embodiment of the application discloses an underwater rotary cleaning assembly, which comprises an annular supporting member 100, a collecting box 200 and a rotary driving mechanism 300, wherein a collecting space 240 is arranged in the collecting box 200, an opening 210 communicated with the collecting space 240 is arranged on a first side surface of the collecting box 200, the first side surface of the collecting box 200 can be attached to the outer surface of an object to be cleaned, so that the opening 210 faces the outer surface of the object to be cleaned, a cleaning water inlet 220 is arranged on the collecting box 200, the rotary driving mechanism 300 is respectively connected with the annular supporting member 100 and the collecting box 200, and the rotary driving mechanism 300 can drive the collecting box 200 to rotate around the circumferential direction of the annular supporting member 100. The underwater rotary cleaning assembly of the embodiment of the application can be sleeved outside the object to be cleaned by the annular support 100 when in use, the rotary driving mechanism 300 can drive the collecting box 200 to rotate along the circumferential direction of the annular support 100, that is, the rotary driving mechanism 300 can drive the collecting box 200 to rotate around the circumferential direction of the object to be cleaned, and in the rotating process, one end, close to the opening 210, of the collecting box 200 is attached to the object to be cleaned. In use, the cleaning water inlet 220 is connected to the water supply pipe, and the cleaning water entering the collecting space 240 through the cleaning water inlet 220 causes the contaminants to separate from the outer circumferential surface of the object to be cleaned, and the separated contaminants will enter the collecting box 200 because the first side of the collecting box 200 is attached to the object to be cleaned. Therefore, the cleaning device does not need to clean the object to be cleaned in a manual mode, and has high safety coefficient; and in the collecting process, the pollutants falling off from the object to be cleaned are collected by the collecting box 200, so that the pollutants such as the anticorrosive coating on the peripheral surface of the object to be cleaned can be prevented from entering the water body. In addition, the rotary driving mechanism 300 can drive the collecting box 200 to rotate around the circumference of the object to be cleaned, so that the object to be cleaned can be cleaned without dead angles, and the cleaning effect is good.

Optionally, the underwater spin cleaning assembly further includes a spray head disposed within the collection space 240. When the cleaning device is used, the spray head can be connected with the water supply pipe, and the water outlet pressure of the water supply pipe can be increased after the spray head is arranged, so that the cleaning effect of the underwater rotary cleaning assembly on objects to be cleaned is improved.

In an alternative embodiment, the collection cartridge 200 is also provided with a wash water outlet 230. In use, the cleaning water outlet 230 may be connected to a return water pipe, so that contaminants in the collection box 200 may be recovered through the return water pipe in time while cleaning the object to be cleaned. The present embodiment can reduce the volume of the collecting box 200 and also reduce the load of the collecting box 200 on the ring support 100. In addition, in the case that the collecting box 200 does not include the washing water outlet 230, the collecting space 240 of the collecting box 200 may include a first space and a second space which are communicated, an included angle is formed between an axis of the first space and an axis of the second space, the first side opening 210 of the collecting box 200 is communicated with the first space, and the first space is disposed toward the object to be cleaned. In this way, the contaminants can be stored in the second space after the cleaning operation is completed, and the contaminants can be prevented from flowing into the water body when the collection box 200 is removed because an included angle exists between the axis of the first space and the axis of the second space.

In an alternative embodiment, the underwater rotary cleaning assembly further includes a first telescopic driving member 410, one end of the first telescopic driving member 410 is connected to the ring-shaped supporting member 100, the other end of the first telescopic driving member 410 is connected to the collecting box 200, and the first telescopic driving member 410 can drive the collecting box 200 to stretch in a first direction, wherein the first direction is a direction approaching or separating from the object to be cleaned. The first telescopic driving member 410 is provided in this embodiment, and the first telescopic driving member 410 can drive the collection box 200 to move close to or away from the object to be cleaned, so that the collection box 200 can adapt to the objects to be cleaned with different size parameters. Further, the first side is further provided with an elastic sealing element, one end of the elastic sealing element away from the first side is attached to the object to be cleaned, the elastic sealing element can deform to compensate the stroke of the first telescopic element in the moving process of the first telescopic element, that is, one end of the elastic sealing element away from the first side is always attached to the object to be cleaned, when the first telescopic element drives the collecting box 200 to move towards the direction close to the object to be cleaned, the elastic sealing element is elastically contracted, at the moment, the distance between the driving box and the object to be cleaned is relatively short, the water pressure sprayed onto the object to be cleaned from the cleaning water inlet 220 is relatively high, and therefore the cleaning effect can be improved; when the first telescopic member drives the collecting box 200 to move in the direction away from the object to be cleaned, the elastic sealing member recovers elastic deformation, and at the moment, the distance between the driving box and the object to be cleaned is far, and the water pressure sprayed onto the object to be cleaned from the cleaning water inlet 220 is small, so that the risk of falling of substances such as an anti-corrosion layer on the object to be cleaned can be reduced. Alternatively, the resilient seal may be a collapsible seal. The first telescopic driving member 410 may be a telescopic device such as a hydraulic cylinder, an air cylinder, a motor, a screw nut mechanism combination, etc.

Alternatively, a chain drive may be used to rotate the collection box 200 about the toroidal support 100, but the chain drive is less efficient in its drive, such that the collection box 200 rotates at a slower rate; and the chain transmission is easy to generate larger tension and impact load at high speed, thereby leading to failure of the chain transmission and further reducing the service life of the underwater rotary cleaning assembly. In an alternative embodiment, the annular support 100 includes an outer ring plate 110, an inner ring plate 120 and a toothed disc 130, the toothed groove on the toothed disc 130 may be disposed on an inner circumferential surface or an outer circumferential surface of the toothed disc 130, the outer ring plate 110 is disposed around the inner ring plate 120, an annular track is formed therebetween, the toothed disc 130 and one of the outer ring plate 110 and the inner ring plate 120 are stacked at intervals along an axial direction of the annular support 100, the rotary driving mechanism 300 includes a bracket 310, a driving source 320 and a gear 330 connected to the driving source 320, the driving source 320 and the collection box 200 are disposed on the bracket 310, the driving source 320 may drive the gear 330 to rotate, the gear 330 is engaged with the toothed disc 130, and the bracket 310 is movably engaged with the annular track. Taking the position state of the underwater rotating cleaning assembly in fig. 2 as an example, the specific operation process is as follows, the driving source 320 drives the gear 330 to rotate, the gear 330 is meshed with the fluted disc 130, and the fluted disc 130 is fixed, so that the gear 330 and the driving source 320 rotate along the circumferential direction of the fluted disc 130, and further drive the support 310 and the collecting box 200 to rotate along the circumferential direction of the fluted disc 130, thereby realizing circumferential rotation of the collecting box 200 around the object to be cleaned, and in the rotating process, the support 310 and the annular track cooperate to realize limiting of the support 310 and the collecting box 200 in the vertical direction. The embodiment of the application drives the collection box 200 to rotate around the axis of the annular support piece 100 in a gear transmission mode, the gear transmission is high in transmission efficiency, the collection box 200 can rotate faster, the cleaning efficiency is higher, and the service life of the gear transmission is longer. Alternatively, the drive source 320 may be an electric motor, a hydraulic motor, or the like. The outer ring plate 110 and the inner ring plate 120 can be fixedly connected through a connecting piece, and the toothed plate and the outer ring plate 110 or the toothed plate and the inner ring plate 120 can also be fixedly connected through the connecting piece.

Optionally, a limiting member 430 may be disposed on the support 310, where the limiting member 430 cooperates with the annular supporting member 100 to limit the support 310 in a vertical direction, but the limiting member 430 may rotate along a circumferential direction of the toothed disc 130 along the support 310, so that a friction force between the limiting member 430 and the annular supporting member 100 is large, which easily causes a problem of jamming between the support 310 and the annular supporting member 100. In an alternative embodiment, the annular support 100 further includes an annular guide plate 140, the annular guide plate 140 is stacked with one of the outer ring plate 110 and the inner ring plate 120 at intervals along the axial direction of the annular support 100, and a first roller 340 and a second roller 350 are rotatably connected to the bracket 310, the first roller 340 being in rolling engagement with the annular track, and the second roller 350 being in rolling engagement with the annular guide plate 140. The annular track of this embodiment may be formed by combining the top surface of the outer ring plate 110 and the top surface of the inner ring plate 120, and after the first roller 340 is disposed, the first roller 340 may roll along the annular track, so that the friction between the support 310 and the annular support 100 may be reduced, so that the driving source 320 may easily drive the collecting box 200 to rotate, and the problem of jamming between the support 310 and the annular support 100 during rotation is avoided. In addition, the second roller 350 is provided in this embodiment, and the second roller 350 may be in rolling fit with the top surface of the annular guide plate 140, so that the acting force of the partial support 310 and the collection box 200 on the first roller 340 may be balanced, so that the operation of the underwater rotary cleaning assembly is more stable.

In an alternative embodiment, the outer circumferential surface of the first roller 340 is provided with a first limit groove in a ring shape along the circumferential direction, the first roller 340 is in rolling fit with the ring-shaped rail through the first limit groove, and the first limit groove is in limit fit with the ring-shaped rail in the axial direction of the ring-shaped rail and the width direction of the ring-shaped rail, so that the support 310 is in limit fit in the axial direction of the ring-shaped rail and the width direction of the ring-shaped rail, and further the support 310 is in limit in the vertical direction, and the underwater rotary cleaning assembly operates more stably; it should be noted that, the annular track in this embodiment is formed by combining the inner peripheral surface of the outer ring plate 110 and the outer peripheral surface of the inner ring plate 120, when the plane of the inner ring plate 120 and the plane of the outer ring plate 110 are located at the same horizontal plane, the first roller 340 may be at least one, and at this time, the first limit groove of the first roller 340 is simultaneously matched with the outer peripheral surface of the inner ring plate 120 and the inner peripheral surface of the outer ring plate 110, and when the plane of the inner ring plate 120 and the plane of the outer ring plate 110 are not located at one plane, the number of the first rollers 340 is at least two, wherein the first limit groove of one first roller 340 is matched with the outer peripheral surface of the inner ring plate 120, and the first limit groove of the other first roller 340 is matched with the inner peripheral surface of the outer ring plate 110.

And/or, the outer circumferential surface of the second roller 350 is provided with a second limit groove in a ring shape along the circumferential direction thereof, the second roller 350 is in rolling fit with the ring-shaped guide plate 140 through the second limit groove, and the second limit groove is in limit fit with the ring-shaped guide plate 140 in the axial direction of the ring-shaped guide plate 140 and the width direction of the ring-shaped guide plate 140, so that the operation of the underwater rotary cleaning assembly is more stable.

Optionally, the underwater rotary washing assembly further includes an annular supporting plate 150 overlapped with the inner ring plate 120 or the outer ring plate 110, and the supporting plate 150 is positioned on the top layer of the annular support 100, and the supporting plate 150 covers the first roller 340 and the second roller 350 in the circumferential direction of the annular support 100. If the support plate 150 is not provided, foreign materials in the water may collide with the first roller 340 or the second roller 350 in the axial direction of the ring-shaped support 100, which may cause damage to the first roller 340 or the second roller 350. After the support plate 150 is disposed, the support plate 150 may reduce the risk of foreign matters in the water striking the first roller 340 and the second roller 350 because the support plate 150 may cover the first roller 340 and the second roller 350.

If the outer ring plate 110, the inner ring plate 120, the fluted disc 130 and the annular guide plate 140 are in an integrated annular structure, the annular support member 100 needs to be sleeved on the outer circumferential surface of the object to be cleaned from the top end or the bottom end of the object to be cleaned, so that the flexibility of the underwater rotary cleaning assembly is reduced. In an alternative embodiment, outer ring plate 110, inner ring plate 120, toothed disc 130, and annular guide plate 140 each include first arcuate plate 101 and second arcuate plate 102 that are detachably connected to form an annular structure.

In the embodiment of the present application, the first arc plate 101 and the second arc plate 102 are detachably connected, and when the first arc plate 101 and the second arc plate 102 are connected, each first arc plate 101 and each second arc plate 102 can be correspondingly combined one by one to form an outer ring plate 110, an inner ring plate 120, a fluted disc 130 and an annular guide plate 140 respectively; when the annular supporting member 100 is required to be sleeved on the outer peripheral surface of the object to be cleaned, the outer annular plate 110, the inner annular plate 120, the fluted disc 130 and the annular guide plate 140 can be separated into a first arc plate 101 and a second arc plate 102 respectively, then the first arc plate 101 and the second arc plate 102 are sleeved on the outer peripheral surface of the object to be cleaned, and finally the first arc plate 101 and the second arc plate 102 are respectively connected to form the outer annular plate 110, the inner annular plate 120, the fluted disc 130 and the annular guide plate 140. The present solution thus allows to nest the annular support 100 from any position of the object to be cleaned, thus increasing the flexibility of the underwater rotary cleaning assembly.

Optionally, both ends of the first arc plate 101 may be connected to both ends of the second arc plate 102 in a one-to-one correspondence through bolts, when the first arc plate 101 and the second arc plate 102 are separated, the bolts at both ends need to be removed, and after the object to be cleaned is sleeved, the bolts between the first arc plate 101 and the second arc plate 102 need to be assembled, so that the structure is complicated when the annular support 100 is sleeved into the object to be cleaned.

When the annular supporting member 100 is sleeved on the outer peripheral surface of the object to be cleaned, the second end of the first arc-shaped plate 101 and the second end of the second arc-shaped plate 102 are separated, one of the first arc-shaped plate 101 and one of the second arc-shaped plates 102 is shifted to expand the first arc-shaped plate 101 and the second arc-shaped plate 102, and then the annular supporting member 100 can be sleeved on the outer peripheral surface of the object to be cleaned.

As shown in fig. 6, a first end of one of the first arc-shaped plate 101 and the second arc-shaped plate 102 of each layer extends to form a protruding portion 160, at least one first arc-shaped plate 101 is provided with the protruding portion 160, at least one second arc-shaped plate 102 is provided with the protruding portion 160, the protruding portion 160 is embedded to form a sleeve 170, the axis of each sleeve 170 is collinear with the axis of the connecting shaft 420, the sleeve 170 is rotatably sleeved on the outer circumferential surface of the connecting shaft 420, a limiting portion 180 is protruding from the bottom end of the rotating shaft, the bottom end of the sleeve 170 located at the bottommost layer is in limiting fit with the limiting portion 180, the end faces of two adjacent sleeves 170 are in fit, that is, the bottom end face of one sleeve 170 is in fit with the top end face of the sleeve 170 located below the sleeve, limiting between the sleeves 170 is achieved, and the bottom end of the sleeve 170 located at the bottommost is in fit with the limiting portion 180.

The first arc plate 101 or the second arc plate 102 in this embodiment may be located in the limit groove of the limit member 430, and at this time, the planes where the first arc plate 101 and the second arc plate 102 are located may be located in the same plane, that is, the planes where the first arc plate 101 and the second arc plate 102 of the fluted disc 130 are located are also located in the same plane, so that the first arc plate 101 and the second arc plate 102 of the fluted disc 130 are staggered during assembly or in use, thereby causing the problem that the gear 330 is disengaged from the fluted disc 130. This embodiment may be combined with the embodiment of the connecting shaft 420, where a second end of one of the first arcuate plate 101 and the second arcuate plate 102 is connected with a stop 430.

Optionally, the lifting assembly 500 may be a winch, and the winch may lift the underwater rotating cleaning assembly, but when the winch is used to lift the underwater rotating cleaning assembly, since the rope of the winch is a flexible rope, the flexible rope can make the underwater rotating cleaning assembly shake back and forth in the process of driving the underwater rotating cleaning assembly to rise or fall, so that the object to be cleaned can be collided, and damage to the underwater rotating cleaning assembly is easily caused. In another alternative embodiment, the lifting assembly 500 includes a second telescopic driving member 510 and at least two clamping jaw arms 520, the clamping jaw arms 520 can clamp or release the object to be cleaned, the at least two clamping jaw arms 520 are disposed on the frame 440 at intervals along the axial direction of the annular supporting member 100, at least one of the two clamping jaw arms 520 is slidably connected with the frame 440, a first end of the second telescopic driving member 510 is disposed on the frame 440, a second end of the second telescopic driving member 510 is connected with the slidable clamping jaw arms 520, the second telescopic driving member 510 can drive the clamping jaw arms 520 to slide, and the at least two clamping jaw arms 520 are clamped alternately to drive the underwater rotary cleaning assembly to move along the extending direction of the object to be cleaned. According to the embodiment of the application, the clamping jaw arm 520 drives the underwater rotary cleaning assembly to move along the extending direction of the object to be cleaned, and the clamping jaw arm 520 is of a rigid structure, so that the clamping jaw arm 520 is not easy to shake in the process of driving the underwater rotary cleaning assembly to move, and the underwater rotary cleaning assembly is prevented from colliding with the object to be cleaned. For convenience of description, the jaw arm 520 connected to the second telescopic driving member 510 is defined as a first jaw arm, and the other jaw arm 520 is defined as a second jaw arm, and the example in which the jaw arm 520 drives the underwater rotary cleaning assembly to rise is shown in fig. 7: when the second clamping jaw arm clamps the object to be cleaned, the first clamping jaw arm releases the object to be cleaned, the first clamping jaw arm is driven to move upwards by retracting the second telescopic driving piece 510, the object to be cleaned is clamped by the first clamping jaw arm, the second clamping jaw arm releases the object to be cleaned, then the second telescopic driving piece 510 stretches out and drives the rack 440 and the second clamping jaw arm to move upwards, the underwater rotary cleaning assembly is driven to move upwards, and the clamping jaw arm 520 can drive the underwater rotary cleaning assembly to ascend by repeating the above processes. The process of the jaw arm 520 driving the underwater rotary cleaning assembly to descend is opposite to the above process, and will not be described in detail herein. Alternatively, the second telescopic driving member 510 may be a hydraulic cylinder, an air cylinder, or the like. The jaw arm 520 may be slidably engaged with the frame 440 via a guide rail.

Alternatively, the clamping jaw arm 520 may comprise two oppositely disposed integral clamping arms and a driving member, the driving member may drive the two clamping arms to move in opposite directions so as to clamp the object to be cleaned; or the two clamping arms are driven to move in the direction away from each other, so that the object to be cleaned is released. Although the structure can realize the clamping and releasing of the object to be cleaned, as the clamping arm is integrated, when the size of the object to be cleaned is greatly changed, the clamping arm cannot clamp the object to be cleaned.

The second clamping arms 522 can rotate relative to the first clamping arms 521, and when the clamping jaw arms 520 are arranged on the outer circumferential surface of the object to be cleaned, the clamping driving piece 523 can drive the second clamping arms 522 to rotate along the second direction, so that the distance between the two second clamping arms 522 is increased, and the object to be cleaned can enter the clamping jaw arms 520 conveniently; when the object to be cleaned is required to be clamped, the clamping driving piece 523 drives the second clamping arms 522 to rotate along the third direction, so that the distance between the two second clamping arms 522 is reduced, and the object to be cleaned is clamped. The third direction here is opposite to the second direction. It can be seen that the distance between the two second clamping arms 522 can be adjusted by rotating the second clamping arms 522, so that the clamping jaw arms 520 can clamp the object to be cleaned when the size of the object to be cleaned is greatly changed. Alternatively, the clamping driving member 523 may be a hydraulic cylinder, an air cylinder, a motor, a screw-nut mechanism, or the like.
