Referring to fig. 1 and 2 in combination, in an embodiment of the present invention, the immersed tube sinking apparatus includes a guide 1 and a sinking assembly 2; wherein, at least part of the structure of the guide piece 1 is used for being inserted into the water bottom; the sinking assembly 2 comprises a connecting frame 22 and a sinking body 21, the connecting frame 22 is used for being fixedly connected with the sinking pipe 8, the sinking body 21 is detachably connected to one side of the connecting frame 22 departing from the sinking pipe 8, and the sinking body 21 is connected with the guide piece 1 and can move along the extending direction of the guide piece 1.
In an embodiment of the present invention, the guiding member 1 is mainly used for positioning the preset placing position of the immersed tube 8, and guiding the immersed tube 8 when it is immersed, so as to accurately sink the immersed tube 8 to the preset placing position. It can be fixed by inserting into the water bottom, certainly, in order to improve the fixing effect to guide member 1, can also further set up the grip block in the part that guide member 1 exposes on the surface of water in order to connect the fixed object on bank. So make stable the presetting of being fixed in immersed tube 8 of guide 1 and lay the position, the fluctuation that reduces rivers leads to the fact the guide 1 to rock to can improve the guide precision of sinking the immersed tube 8 of guide 1. The connecting frame 22 is mainly used for being fixedly connected with the immersed tube 8, so that the immersed tube 8 can drive the immersed assembly 2 to descend along with the immersed tube. The sinking body 21 is mainly used for being connected with the guide member 1, so that the sinking assembly 2 can descend along the extending direction of the guide member 1 when sinking along with the sinking pipe 8, thereby indirectly realizing the sinking of the sinking pipe 8 for guiding.
When the immersed tube 8 is immersed in the immersed tube immersion device in the technical scheme of the invention, at least part of the structure of the guide piece 1 is used for being inserted into the water bottom at the preset placing position of the immersed tube 8, so that the guide piece 1 is positioned at the preset immersion position of the immersed tube 8. And then the connecting frame 22 of the sinking assembly 2 is fixedly connected with the sinking pipe 8, so that the sinking pipe sinking device and the sinking pipe 8 are fixed. Since the sinking body 21 of the sinking assembly 2 is connected with the guide 1 and can move along the extending direction of the guide 1. Make immersed tube 8 go on under self gravity and the in-process of sinking, lead to the motion of sinking body 21 through guide 1, indirect realization leads to the process of sinking of immersed tube 8, that is to say that make immersed tube 8 only can sink along the extending direction of guide 1. Compared with the prior art, the sinking position of the sinking pipe 8 is easy to deviate from the preset sinking position because the sinking barge is easily influenced by water flow impact in the sinking process of the sinking pipe 8. In the scheme, the immersed tube 8 can be positioned by the guide piece 1 in the process of immersion, so that the immersed tube 8 is accurately arranged above the preset immersion position; and under the indirect guiding action of the guiding piece 1, the immersed tube 8 can be accurately immersed to a preset immersion position, so that the immersion construction precision of the immersed tube 8 is improved.
And, set up to including link 22 and heavy body 21 with sinking subassembly 2 for this sinks subassembly 2 can be connected through link 22 and immersed tube 8, and is convenient for set up fixed knot structure on link 22 in order to fix and sinks subassembly 2 and immersed tube 8, thereby can improve the convenience of immersed tube 8 when fixing with immersed tube sinking device. Further, the sinking body 21 is detachably connected to a side of the connecting frame 22 facing away from the sinking tube 8, so that the sinking body 21 can be detached from the connecting frame 22 for replacement when damaged. Therefore, the problem that the whole sinking assembly 2 needs to be replaced when one part of the sinking body 21 is damaged is avoided, and the replacement cost of the sinking pipe sinking device is reduced. The sinking body 21 is connected to the side of the connecting frame 22 departing from the sinking pipe 8, so that the sinking body 21, the connecting frame 22 and the sinking pipe 8 are sequentially distributed from top to bottom. The sinking body 21 and the sinking pipe 8 can be installed on the connecting frame 22 conveniently because of large installation space, and the possibility of interference between the sinking body 21 and the sinking pipe 8 because of being arranged on the same side of the connecting frame 22 is avoided, so that the safety of the sinking body 21 and the sinking pipe 8 during installation and fixation is improved.
In an embodiment of the present invention, the sinking body 21 is provided with a slide rail 21a, the slide rail 21a extends along a moving direction of the sinking body 21, and at least a part of the structure of the guiding element 1 is embedded in the slide rail 21a and abuts against an inner wall of the slide rail 21 a.
It can be understood that the sinking body 21 is connected with the guiding element 1 through the slideway 21a, so that the sinking body 21 can move along the extending direction of the guiding element 1, that is, the guiding element 1 can guide the sinking assembly 2 along with the sinking of the sinking pipe 8. Meanwhile, the connecting structure of the sinking body 21 and the guide piece 1 is simplified, so that the sinking body and the guide piece do not need to be provided with a complex structure for connection, and the processing and manufacturing cost of the sinking pipe sinking device can be reduced. And locate slide 21a on the body 21 is put to the heavy, guaranteed the self intensity of guide 1 and improved its anti wave nature to rivers to can improve the stability of guide 1 to the heavy in-process of tub 8 heavy. Further, because the inner wall of the slide way 21a can be distinguished from other wall surfaces of the sinking body 21 and the roughness of the inner wall is relatively low, that is, the inner wall of the slide way 21a is smooth, the friction force of the sinking body 21 when moving along the extending direction of the guide piece 1 can be reduced, and the sinking efficiency of the sinking pipe 8 can be improved; the great wear of the sinking body 21 and the guide 1 due to the relative movement is also reduced, so that the service life of the sinking body 21 and the guide 1 can be prolonged. Of course, the application is not limited thereto, and in other embodiments, the connection between the sinking body 21 and the guiding element 1 may also be a combination of a sliding rail and a sliding block, that is, the guiding element 1 is provided with a sliding rail, and the sliding rail extends along the extending direction of the guiding element 1; the sinking body 21 is provided with a sliding block which is connected with the sliding rail in a sliding way.
Referring to fig. 1 and fig. 7 in combination, in an embodiment of the present invention, the sinking body 21 includes a main body portion 211 and two clamping arms 212; the main body part 211 has two opposite ends, and one end of the main body part 211 is detachably connected to one side of the connecting frame 22 departing from the sinking tube 8; the two clamping arms 212 are arranged at the other end of the main body part 211 and are positioned at two opposite sides of the main body part 211 in the movement direction vertical to the sinking body 21, and the opposite surfaces of the two clamping arms 212 and the end surface of the main body part 211 close to one end of the two clamping arms 212 enclose to form a slide way 21 a.
It will be appreciated that since the guide member 1 is pre-fixed to the sinking tube 8 at a predetermined position, the main body 211 of the sinking body 21 and the guide member 1 are generally coupled by abutting the sinking body 21 against the guide member 1. And the slide way 21a is formed by the two clamping arms 212 and the main body part 211 in an enclosing way, so that the slide way 21a is not formed into a closed shape. Therefore, when the main body 211 of the sinking body 21 approaches the guiding element 1, the guiding element 1 can be inserted into the sliding channel 21a from the opening formed at the end of the two clamping arms 212 far from the main body 211, and the connection of the guiding element 1 of the sinking body 21 can be rapidly completed. So reduced both and carried out the complexity of butt joint under comparatively complicated water operating mode to can improve the butt joint efficiency of sinking body 21 and guide 1. Meanwhile, the slide is only formed by the body part 211 of the sinking body 21 and the two clamping arms 212 in a surrounding manner, namely the slide way 21a only comprises three connected inner walls, so that the complexity of the slide way 21a forming can be reduced; the production raw material required for forming the chute 21a is also made smaller, so that the production and manufacturing costs can be reduced. Furthermore, the opposing surfaces of the two holding arms 212 and the end surface of the main body portion 211 near one end of the two holding arms 212 enclose the slideway 21a, so that the center line of the two holding arms 212 parallel to the horizontal plane and the center line of the main body portion 211 parallel to the horizontal plane can be positioned on the same horizontal plane. Thus, the thickness of the sinking body 21 can be reduced, and the occupation of space can be reduced. Further, two centre gripping arms 212 and main part 211 can be structure setting as an organic whole to improve both intensity at the junction and guarantee to sink the centre gripping linkage effect of body 21 to guide 1, and then improve the guide effect of guide 1 to sinking body 21. Of course, the two clamp arms 212 and the main body portion 211 may be provided in a separate structure and fixed by welding. Therefore, the processing complexity can be reduced by separately and independently manufacturing, and the two parts are ensured to have stable connection effect by adopting a welding mode when being assembled into a whole; in this case, the slide 21a is formed without forming a hole in the main body 211, that is, by assembling the two clamp arms 212 and the main body 211, so that the complexity of molding the slide 21a can be further reduced. In addition, the present invention is not limited to this, and in another embodiment, the slide rail 21a may be formed by opening a through hole in the main body portion 211 of the settling body 21. In an embodiment of the present invention, two slideway stiffeners 213 are disposed at the connection between each clamping arm 212 and the main body portion 211, and the two slideway stiffeners 213 are respectively disposed at two opposite sides of the main body portion 211 in the moving direction of the sinking body 21.

The two slideway reinforcing ribs 213 are respectively arranged on the two opposite sides of the main body part 211 in the movement direction of the sinking body 21, so that the reinforcing effect of the slideway reinforcing ribs 213 on the connection strength of the clamping arm 212 and the main body part 211 can be ensured; the number of the slideway reinforcing ribs 213 is reduced, so that the complexity of the structure of the slideway reinforcing ribs at the joint of the slideway reinforcing ribs and the slideway reinforcing ribs is reduced, and the production and manufacturing cost is reduced. In an embodiment of the present invention, the ends of the two clamping arms 212 far from the main body portion 211 are provided with first lifting members 2111, the two first lifting members 2111 are arranged oppositely, the end of the main body portion 211 far from the two clamping arms 212 is provided with two second lifting members 2111, the two second lifting members 2111 are located at two opposite sides of the main body portion 211 perpendicular to the movement direction of the sinking body 21, and the two first lifting members 2111 and the two second lifting members 2111 are provided with lifting holes 2111 a.
It can be understood that the first lifting member 2111 and the second lifting member 2111 are provided to facilitate the lifting assembly and transportation of the sinking assembly 2, that is, the connection between the sinking body 21 and the lifting device can be realized by the hook of the lifting device passing through the lifting hole 2111a and hooking to the first lifting member 2111 and the second lifting member 2111, and the sinking body 21 is lifted by the lifting device. And the first lifting part 2111 and the second lifting part 2111 are provided with lifting holes 2111a, so that the connection structure of the sinking body 21 and the lifting device can be simplified, and the operation personnel can conveniently connect the lock hook with the first lifting part 2111 and the second lifting part 2111 under the complicated underwater working condition.

The slide hole 212a also provides a certain installation space for the contact piece 3, and can prevent the contact piece 3 from being easily damaged due to most of the contact piece being exposed to the outside, thereby extending the service life of the contact piece 3. The slide hole 212a may be square, circular, or the like, and may be shaped according to the cross-sectional shape of the abutment 3. In addition, in another embodiment, the contact member 3 may have one end rotatably connected to the holding arm 212 and the other end contacting the contact member 3 located in the slide rail 21a by rotating the contact member 3 with respect to the holding arm 212.

The embedded arrangement of the abutting cushion can make the abutting cushion be accommodated in the abutting piece 3, or in the slide reinforcing rib 213, or in the main body part 211 after being correspondingly deformed when the abutting cushion is pressed by the abutting of the guide piece 1. At this time, the abutting piece 3, the slide rail reinforcing rib 213, and the main body portion 211 can still have a good clamping and fixing effect on the guide 1 by performing rigid abutment with the guide 1 at a position where the abutting cushion is not provided. Simultaneously, the setting of inlaying of butt blotter also can increase butt blotter and butt piece 3, butt blotter and slide strengthening rib 213 and butt blotter and the area of contact of main part 211 to can strengthen the fixed stability of butt blotter, reduce the butt blotter and cause the possibility that drops because long-time friction when sinking body 21 moves along the extending direction of guide 1, guarantee that sinking body 21 moves along the normal stable the going on of the extending direction motion of guide 1.

Meanwhile, the arrangement is only required to arrange the connecting hole on the inner side plate 231, and a complex structure is not required to be arranged to fix the clamping fastener 24, so that the strength of the frame side seat 230 can be ensured, the influence of water flow fluctuation on the frame side seat can be reduced, and the main body part 211 can be further ensured to be stably arranged in the accommodating groove 22 a. Moreover, the bolt needs water and oxygen in an oxidizing environment, and the underwater working condition has low oxygen content, so that the bolt is not easy to oxidize and the service life of the clamping fastener 24 can be prolonged. Of course, the present application is not limited thereto, and in other embodiments, the clamping fastener 24 and the side seat connecting hole 231a may be elastically fastened and fixed, that is, two end portions of the clamping fastener 24 are provided with convex caps, and one convex cap passes through the clamping mounting hole 23a and the side seat connecting hole 231a by elastic extrusion and then cooperates with the other convex cap to clamp and fix the clamping member 23 and the inner side plate 231.
In an embodiment of the present invention, the inner side plates 231 of the two opposite frame side bases 230 are convexly provided with clamping mounting plates 234, and the clamping mounting plates 234 are provided with clamping mounting holes 23 a; the side plate connecting plates 232 of the two frame side seats 230 which are oppositely arranged are convexly provided with clamping reinforcing ribs 235, the clamping reinforcing ribs 235 are connected to the inner side plate 231, the outer side plate 232 and the clamping mounting plate 234, and in the direction that the clamping reinforcing ribs 235 are far away from the side plate connecting plates 232, the distance between one side of the clamping reinforcing ribs 235 facing the inner side plate 231 and the outer side plate 232 is reduced.
It will be appreciated that the provision of the clamp mounting plate 234 may give the clamp 23a mounting position such that the height of the inner plate 231 may be the same as the height of the main body portion 211, without the need to provide a higher height in order to mount the clamp 23.

It can be understood that since the junction of the pipe main body segment 81 and the pipe connection segment 82 is formed as a stepped surface, there is a difference in height between the pipe main body segment 81 and the main body portion 211 of the sinking body 21 and between the pipe connection segment 82 and the main body portion 211 of the sinking body 21. At this time, the first frame body 2210 and the second frame body 2220 with different support strengths are adopted to connect the pipe main body segment 81 and the frame side seat 230, the pipe connection segment 82 and the frame side seat 230, respectively, so that the stability of the connection of the immersed tube 8 with the frame side seat 230 at each segment can be improved, and the stable connection of the immersed assembly 2 and the immersed tube 8 is ensured. And the first frame body 2210 and the pipe main body section 81 are detachably connected, and the second frame body 2220 and the pipe connection section 82 are detachably connected, so that after the sinking of the sinking pipe 8 is completed, the connection of the first frame body 2210 and the pipe main body section 81 and the connection of the second frame body 2220 and the pipe connection section 82 can be detached, so that the sinking assembly 2 can be recovered and reused, thereby improving the environmental protection of the use of the sinking assembly 2.

It can be understood that the first embedded component 6, the second embedded component 77 and the immersed tube 8 are simultaneously formed into a whole by respectively inserting the first embedded component 6 and the second embedded component 77 into the tube main body section 81 and the tube connecting section 82 when the immersed tube 8 is formed. When the subsequent sinking pipe 8 is connected with the first frame 2210 and the second frame 2220, it is not necessary to separately set a connection structure on the formed sinking pipe 8 with a larger volume and higher hardness to connect with the first frame 2210 and the second frame 2220, that is, the complexity of setting the connection structure on the sinking pipe 8 is reduced, thereby improving the convenience of connecting the sinking pipe 8 with the first frame 2210 and the second frame 2220.

It can be understood that, by pre-embedding the first embedded rod 61 in the main pipe segment 81, the occupation of the space in the main pipe segment 81 can be reduced due to the relatively small volume of the first embedded rod 61, thereby ensuring that the main pipe segment 81 has high strength. The arrangement of the connection seat body 611 can increase the contact area between the first embedded rod 61 and the first frame body 2210, so that the connection strength between the two can be improved. The frame body mounting groove 611a is configured to align the first frame body 2210 to achieve a positioning effect, so that the first frame body 2210 is accurately mounted at a predetermined fixed position of the tube main body segment 81, and the frame body limiting member 6111 of the subsequent connection seat body 611 can be accurately moved into the limiting groove 2211a of the first frame body 2211.

It can be understood that, through pre-buried pole 71 in pipe connection section 82, can reduce the occupation in the space in pipe connection section 82 because the volume of second pre-buried pole 71 is less relatively to guarantee that pipe connection section 82 has higher intensity. The tightening of the nut 72 can improve the stability of the connection between the second frame body 2220 and the pipe connection section 82, so that the connection between the connection frame 22 and the sinking pipe 8 is stable; meanwhile, the connection process of the two is simplified, so that the operator can fix the two conveniently. The second upper support plate 2222 may increase a contact area of the second frame body 2221 and the frame side seat 230 so that the second frame body 2221 can stably support the frame side seat 230; meanwhile, the pressure loss of the surface of the frame side seat 230 due to stress concentration caused by too small contact area between the frame side seat and the second frame body 2220 can be avoided, so that the safety of the second frame body 2220 and the frame side seat 230 in the abutting process can be improved.

Further, the second embedded component 77 further includes a second embedded plate 73, and the second embedded plate 73 is disposed at an end of the second embedded rod 71 away from the screwing nut 72, and is used for being embedded in the pipe connection section 82. The contact area between the second embedded component 77 and the pipe connecting section 82 can be increased through the second embedded plate 73, so that the connection stability between the second embedded component 77 and the pipe connecting section 82 can be improved after the pipe connecting section 82 is formed.
In addition, the connection manner of the first frame 2210 and the pipe body segment 81 is that the partial structure of the first frame body 2211 of the first frame 2210 is embedded in the frame mounting groove 611a of the connection seat body 611 of the first embedded component 6, and then the frame stopper 6111 disposed on the connection seat body 611 is clamped into the stopper groove 2211a of the first frame body 2211, so as to fix the first frame 2210 and the pipe body segment. The connection mode of the second frame body 2220 and the pipe connection section 82 is that the second embedded rod 71 of the second embedded component 77 penetrates through the second lower support plate 2223 of the second frame body 2220, and the screwing nut 72 is sleeved on the second embedded rod 71 and abuts against the second lower support plate 2223, so that the fixation of the second embedded rod 71 and the second lower support plate 2223 is realized. When the connecting frame 22 is connected to the sinking pipe 8, the first frame body 2210 and the pipe body segment 81 may be connected first. At this time, since the frame body mounting groove 611a is relatively large, and the distance between the tube main body segment 81 and the frame side seat 230 is relatively short, the first frame body 2210 and the tube main body segment 81 are conveniently aligned and mounted, and it can be ensured that the connecting frame 22 is preliminarily and accurately mounted at the predetermined fixing position of the sinking tube 8. After the first frame body 2210 of the connecting frame 22 and the pipe body section 81 of the sinking pipe 8 are accurately installed in an aligned position, the second frame body 2220 of the connecting frame 22 and the pipe connecting section 82 of the sinking pipe 8 are also oppositely arranged, so that the second embedded rods 71 of the second embedded assemblies 77 can conveniently penetrate through the screw installation holes 2223a of the second lower support plate 2223 of the second frame body 2220. That is, accurate installation of the second frame body 2220 and the pipe coupling section 82 may be facilitated by pre-aligning installation of the first frame body 2210 and the pipe body section 81 in the coupling process, so that the coupling complexity is reduced by different coupling manners adopted by the first frame body 2210 and the pipe body section 81, respectively, the second frame body 2220 and the pipe coupling section 82 in the coupling process of the coupling frame 22 and the immersed tube 8, thereby improving the convenience of coupling the coupling frame 22 and the immersed tube 8.

It will be appreciated that each corner region is provided with a screw mounting hole 2223a so that the pipe connecting section 82 can be pre-embedded with a plurality of second pre-embedded members 77 correspondingly. So through the quantity that increases second pre-buried subassembly 77, can increase the fastening force to second lower supporting plate 2223 to further improve the stability that second support body 2220 and coupling for pipe section 82 are connected. The screw mounting holes 2223a are formed in the corner regions, so that the second lower support plate 2223 can be more stably abutted against the surface of the pipe connecting section 82 by increasing the fastening force to the periphery of the second lower support plate 2223. In addition, every two adjacent screw mounting holes 2223a of the four screw mounting holes 2223a are symmetrically arranged around the center line of the second lower support plate 2223, so that the abutting force of the screwing nut 72 of the second embedded component 77 on each part of the second lower support plate 2223 can be ensured to be uniform, the connecting frame 22 is stably mounted, the possibility of inclination is reduced, and the immersed tube 8 is stably immersed to the preset immersion position.

It can be appreciated that since the height between the rack side seats 230 and the pipe coupling sections 82 is relatively high, the height of the second rack body 2220 is also relatively high. And the support reinforcing ribs 2224 can reinforce the support strength of the second support body 2220, thereby improving the support effect of the second support body 2220 to ensure the stable support of the second support body 2220 on the support side seat 230 and the sinking body 21. The distance between one side of the frame body reinforcing rib 2224 far from the second frame main body 2221 and the second frame main body 2221 is reduced, and then the raw materials required for producing the frame body reinforcing rib 2224 can be reduced under the reinforcing effect of the frame body reinforcing rib 2224, so that the manufacturing cost of the second frame body 2220 can be reduced. The frame body reinforcing ribs 2224 may be fixed by welding, that is, the stability of fixing may be ensured; it is also avoided that the second frame main body 2221, the second upper support plate 2222 and the second lower support plate 2223 have an influence on their own structure due to the fixing structure provided to fix the frame body reinforcing ribs 2224, thereby ensuring the own strength of the second frame main body 2221, the second upper support plate 2222 and the second lower support plate 2223.
