The invention provides a sinking pipe sinking device.

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.

It can be understood that the arrangement of the slideway reinforcing rib 213 can enhance the strength of the clamping arm 212 and the main body portion 211 at the joint to improve the connection effect of the clamping arm and the main body portion 211, and further can further ensure the clamping connection effect of the sinking body 21 on the guiding element 1, so as to further improve the guiding effect of the guiding element 1 on 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. Of course, the present application is not limited thereto, and in other embodiments, the connection between the locking hook and the first lifting element 2111 and the second lifting element 2111 may be through a snap connection. In addition, the two first lifting parts 2111 are arranged at one ends of the two clamping arms 212 far away from the main body part 211, and are arranged oppositely; the two second lifting members 2111 are located at two opposite sides of the main body 211 perpendicular to the movement direction of the sinking body 21, so that the two first lifting members 2111 and the two second lifting members 2111 are distributed at two opposite ends of the sinking body 21, that is, a large span is formed between the two first lifting members 2111 and the two second lifting members 2111, the connection stability of the sinking body 21 is improved, and the possibility of shaking of the periphery of the sinking body 21 is reduced.

In an embodiment of the present invention, the immersed tube sinking device further includes at least two abutting members 3, wherein two abutting members 3 are respectively selected and movably connected to one of the clamping arms 212, the two abutting members 3 move along a direction approaching or separating from each other, the two abutting members 3 can be fixed to the clamping arm 212 corresponding to the abutting member 3 in a limited manner, the two clamping members 23 approach each other to clamp the fixed guide member 1, and both the two abutting members 3 and the end surface of the main body portion 211 near one end of the guide member 1 can abut against the guide member 1 located in the slide way 21 a.

It will be appreciated that the two abutments 3 are movably arranged to the clamping arm 212 such that the distance between the two abutments 3 can be adjusted. Distance between two centre gripping arms 212 this moment can set up and be greater than the guide 1 and be close to the longitudinal section of the terminal surface of the one end of guide 1 on the longitudinal section between the relative both sides of main part 211 for the main part 211 of sinking body 21 can carry out preliminary counterpoint through two centre gripping arms 212 when being close to guide 1 and butt joint, and the rethread two butts are close to guide 1 each other and carry out the centre gripping fixedly. The main body 211 of the sinking body 21 and the guide 1 are thus reduced in the accuracy of alignment at the time of butt-joint connection, so that the sinking efficiency of the sinking tube 8 can be further improved. Furthermore, the distance between the two contact pieces 3 can be adjusted so that the main body portion 211 of the sinking body 21 can be abutted against the guide pieces 1 of different sizes, thereby improving the versatility of the use of the sinking body 21. Meanwhile, the end faces of the two abutting pieces 3 and the main body part 211 close to one end of the guide piece 1 can abut against the guide piece 1 positioned in the slide rail 21a, so that the clamping area of the sinking body 21 to the guide piece 1 can be reduced, the friction force between the two can be reduced, the friction force caused by the movement of the sinking body 21 relative to the guide piece 1 can be improved, and the sinking efficiency of the sinking pipe 8 can be improved. In addition, two butt parts 3 are close to each other and realize the centre gripping fixed to guide 1, and two butt parts 3 are kept away from each other and realize the phase separation to guide 1 for both can dismantle separately and be convenient for respective recovery processing. The number of the abutting pieces 3 may be two, or of course, may be more, and more abutting pieces may be distributed at intervals in the circumferential direction of the guide 1 to clamp, abut and fix the guide 1 from different directions.

In an embodiment of the present invention, the two holding arms 212 are provided with a sliding hole 212a communicating with the sliding way 21a, and one abutting member 3 is slidably embedded in one sliding hole 212 a.

It can be understood that, by slidably connecting the abutting member 3 to the clamping arm 212, the abutting force of the abutting member 3 to the guide member 1 and the sliding direction of the abutting member 3 are parallel, and at this time, the abutting force of the abutting member 3 to the guide member 1 can be more perpendicular to the guide member 1, so that the abutting effect of the abutting member 3 to the guide member 1 can be improved. The abutting part 3 is embedded in the slide hole 212a, so that the abutting part 3 and the clamping arm 212 are distributed compactly, the overall volume of the sinking body 21 is reduced, the descending movement resistance caused by the buoyancy of water flow when the sinking body 21 sinks the sinking pipe 8 is reduced, and the sinking efficiency of the sinking pipe 8 can be further improved. Moreover, the sliding hole 212a also has a guiding function on the sliding of the abutting piece 3, so that the abutting piece 3 can only slide along the extending direction of the sliding hole 212a, the stability of the abutting piece 3 in the sliding process can be improved, the accurate abutting of the abutting piece 3 to the guide piece 1 is ensured, and the clamping and abutting effect of the abutting piece 3 to the guide piece 1 is further improved. 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.

In an embodiment of the present invention, the guide 1 is disposed in a circular shape on a projection plane perpendicular to the moving direction of the sinking body 21, the two abutting pieces 3 abut against a partial position in a half of the circumferential surface of the guide 1, and an end surface of the main body portion 211 near one end of the holding arm 212 abuts against a partial position in the other half of the circumferential surface of the guide 1.

It can be understood that, by the two abutting pieces 3 abutting at partial positions in one half of the peripheral surface of the guide piece 1, the end surface of the main body portion 211 near one end of the clamp arm 212 abuts at partial positions in the other half of the peripheral surface of the guide piece 1. The guide member 1 is limited in the length direction of the main body portion 211, and the two abutting members 3 are arranged oppositely, so that the guide member 1 is limited in the width direction of the main body portion 211. That is, the guide member 1 can be limited in four directions only by the two abutting members 3 and the main body portion 211, and only can move relatively in the height direction of the main body portion 211 (the extending direction of the guide member 1), so that the clamping and fixing effect on the guide member 1 can be ensured, and the guide precision of the guide member 1 on the sinking body 21 can be improved; the arrangement of the clamping mechanism can be simplified, and the manufacturing cost is further reduced.

In an embodiment of the present invention, the two abutting pieces 3 are provided with abutting guiding inclined surfaces 31 on the sides facing the guiding piece 1, and the distance between the two abutting guiding inclined surfaces 31 is increased in the direction that the guiding piece 1 approaches the main body part 211

It can be understood that the abutment guide inclined surface 31 is arranged to make the abutment guide inclined surface 31 of the abutment member 3 parallel to a tangent line of the guide member 1 in the circumferential direction, and can abut against the guide member 1 at the middle position of the abutment guide inclined surface 31 to ensure that the abutment member 3 and the abutment surface can abut against each other in a better fit manner, so that the abutment member 3 can apply an abutment force to the guide member 1 through the abutment guide inclined surface 31, and the clamping and abutting effect of the abutment member 3 on the guide member 1 is further improved. Moreover, the abutting guide inclined surfaces 31 are arranged on the abutting pieces 3, so that when the sinking body 21 is separated from the guide piece 1, namely when the sinking body 21 moves in the direction away from the guide piece 1, the two abutting pieces 3 can automatically slide in the directions away from each other under the guidance of the abutting guide inclined surfaces 31, and the convenience in detaching and separating the sinking body 21 and the guide piece 1 is improved.

In an embodiment of the present invention, the distance between the two chute ribs 213 increases in a direction in which the guide 1 approaches the main body portion 211.

It can be understood that the inclined direction of the side wall of the slideway reinforcing rib 213 and the inclined direction of the abutting guiding inclined surface 31 are symmetrically arranged, that is, the side wall of the slideway reinforcing rib 213 and the tangent line of the guiding element 1 in the circumferential direction are also arranged in parallel, so that the slideway reinforcing rib 213 and the guiding element 1 can be abutted in a better fit manner, and the slideway reinforcing rib 213 can apply the abutting force to the guiding element 1. At this moment, the lateral wall of leading inclined plane 31 and two slide strengthening ribs 213 cooperatees through the butt of two butt pieces 3 and can carry out the centre gripping butt spacingly to two semi-global of guide 1, can further improve the heavy model body and fix the effect to the centre gripping of guide 1 and improve the stability when sinking body 21 moves along the extending direction of guide 1 to sinking body 21, guarantee that immersed tube 8 sinks through sinking body 21 along the extending direction of guide 1 and puts in the preset position of laying through sinking in-process.

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. Of course, the installation of the abutting cushion pad can be more compact due to the embedded arrangement of the abutting cushion pad.

Meanwhile, the accommodating groove 22a also has a guiding effect on the sliding of the main body, so that the main body 211 can only slide along the extending direction of the accommodating groove 22a, thereby improving the stability of the main body 211 in the sliding process, and ensuring the accurate butt joint of the main body 211 and the guide piece 1. Furthermore, the provision of the avoiding groove also reduces the use of production raw materials for the link 22, so that the manufacturing cost of the link 22 can be reduced.

So can guarantee that main part 211 can follow the slip towards guide 1 through first notch to because the formation of second notch reduces the main part and at the frictional force that the slip in-process received, guarantee the butt joint efficiency of main part 211 and guide 1. When the lifting device is installed, the main body part 211 can be placed into the accommodating groove 22a through the first notch along the vertical downward direction, and at the moment, the lifting device can be assisted to lift the main body part 211 into the accommodating groove 22a under the action of the self gravity of the main body part 211; meanwhile, the accommodating groove 22a is formed by only three frame side seats 230 and the frame body 220, which also reduces the production material required for forming the accommodating groove 22a, thereby reducing the manufacturing cost of the connecting frame 22. Wherein the connecting frame engaging lug 22b is fixed to a side seat facing the second notch among the three frame side seats 230.

In an embodiment of the present invention, each frame side seat 230 includes an inner side plate 231, an outer side plate 232, and a side plate connecting plate 232, wherein the inner side plate 231 and the outer side plate 232 are disposed opposite to each other, and the connecting plate is connected between the inner side plate 231 and the outer side plate 232; the inner plate 231 and the outer plate 232 of two frame side seats 230 of the three frame side seats 230 that are oppositely arranged are both connected to one side of the connecting frame 22 that is away from the immersed tube 8, and both ends of the inner plate 231 and the outer plate 232 of the other frame side seat 230 are respectively connected to the inner plates 231 of the two frame side seats 230 that are oppositely arranged.

It can be understood that the inner side plate 231 and the outer side plate 232 are disposed so that the rack side base 230 has a double-layer side wall, thereby improving the strength of the rack side base 230 to reduce the influence of water flow fluctuation on the rack side base, and ensuring that the main body portion 211 is stably disposed in the accommodating groove 22 a. The side plate connection plate 232 can connect the inner plate 231 and the outer plate 232 to form a whole, so that the inner plate 231, the outer plate 232 and the side plate connection plate 232 of one frame side seat 230 can be conveniently mounted on the frame body 220 at one time, and the mounting convenience of the frame side seat 230 is improved.

In an embodiment of the present invention, the sinking assembly 2 further includes at least two clamping members 23, each of the at least two clamping members 23 is detachably connected to the inner side plate 231 of the two frame side seats 230 that are oppositely disposed and located at two opposite sides of the sinking body 21 perpendicular to the moving direction of the sinking body 21, and one side of each of the at least two clamping members 23 facing the frame body 220 abuts against one side of the main body portion 211 facing away from the frame body 220.

It can be understood that, by the clamping piece 23 abutting against the side of the main body portion 211 departing from the rack body 220, the main body portion 211 is clamped and fixed by the clamping piece 23 and the rack body 220 in the height direction (extending direction of the guide 1), and then the main body portion 211 slides along the direction of the main body portion 211 facing the guide 1, so as to improve the stability of the installation of the main body portion 211 in the accommodating groove 22 a. And at least two clamping members 23 are connected to the inner side plates 231 of the two frame side seats 230 which are oppositely arranged and are positioned at two opposite sides of the sinking body 21 which is perpendicular to the movement direction of the sinking body 21. Make holder 23 be relative setting and distribute comparatively evenly, can carry out even butt everywhere to butt main part 211 to improve holder 23 to the spacing effect of main part 211. Of course, the number of the clamp members 23 may be four, six, eight, or the like. In addition, the detachable connection of the clamping piece 23 enables the clamping piece to be detached from the frame side seat 230, so that the lifting device can conveniently lift the main body part 211 from the accommodating groove 22a along the direction that the main body part 211 departs from the frame body 220, and the convenience of detaching the main body part 211 can be improved. Of course, in other embodiments, the detachable connection between the main body 211 of the depositing body 21 and the connecting frame 22 may be: the connecting frame 22 is provided with sliding grooves on two opposite sides perpendicular to the sliding direction of the main body portion 211, and the main body portion 211 is partially embedded in the sliding grooves, so that the main body portion 211 can be separated from the sliding grooves along the extending direction of the sliding grooves, and the main body portion 211 and the connecting frame 22 can be detached and separated.

In an embodiment of the present invention, the clamping member 23 is provided with a clamping mounting hole 23a, the inner side plates 231 of the two frame side bases 230 which are oppositely arranged are provided with side base connecting holes 231a, and the clamping mounting hole 23a and the side base connecting holes 231a are oppositely arranged; the sink assembly 2 further includes a clamp fastener 24, the clamp fastener 24 passing through the clamp mounting hole 23a and the side seat attachment hole 231a such that the clamp 23 is attached to the inner side plate 231.

Specifically, the clamping fastener 24 may be a bolt, and a nut is screwed after the bolt passes through the clamping mounting hole 23a and the side seat connecting hole 231a to connect the clamping member 23 and the inner side plate 231, so that the stability of the connection between the clamping member 23 and the inner side plate 231 can be ensured, the assembling process of the clamping member 23 and the inner side plate 231 can be simplified, and the assembling efficiency can be improved. 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. This reduces the use of raw materials for the inner plate 231, and thus can reduce the manufacturing cost of the frame side base 230. The holding ribs 235 improve the stability of the connection of the holding mounting plate 234, so that the effect of fixing the holding jig 23 can be ensured and the main body portion 211 located in the accommodating groove 22a can be stably abutted. Meanwhile, since the clamping ribs 235 are connected to the inner plate 231, the outer plate 232, and the clamping mounting plate 234, the stability of the connection among the inner plate 231, the outer plate 232, and the side plate connecting plate 232 can be improved, and the overall strength of the frame side base 230 can be improved. And the distance between the side of the clamping reinforcing rib 235 facing the inner side plate 231 and the side far away from the outer side plate 232 is arranged in a decreasing manner, so that the production raw materials for producing the clamping reinforcing rib 235 are larger, and the manufacturing cost of the clamping reinforcing rib 235 can be reduced.

In an embodiment of the present invention, the sinking assembly 2 further comprises a clamping cushion, which is arranged between the clamping member 23 and the main body portion 211.

It can be understood that the clamping cushion can prevent the clamping piece 23 from directly abutting against the surface of the main body part 211, the abutting force applied by the clamping piece 23 can be buffered through the clamping cushion, the possibility that the main body part 211 is damaged due to the fact that the clamping piece 23 abuts against the main body part 211 too tightly is reduced, and therefore the safety of the main body part 211 in the abutting process of the clamping piece 23 can be improved. Wherein, the centre gripping blotter can be rubber pad or silica gel spare to make the centre gripping blotter have certain elasticity and can play better buffering, have certain intensity again simultaneously and can play better isolation and support.

Referring to fig. 2, in an embodiment of the present invention, the sinking tube 8 includes a tube main body section 81 and a tube connecting section 82 connected to one end of the tube main body section 81, and a stepped surface is formed at a connection position of the tube main body section 81 and the tube connecting section 82. The frame body 220 includes a first frame body 2210 and a second frame body 2220, the first frame body 2210 and the pipe main body section 81 are detachably coupled, the second frame body 2220 and the pipe coupling section 82 are detachably coupled, and the inner side plate 231 and the outer side plate 232 of two frame side seats 230, which are oppositely disposed, of the three frame side seats 230 are coupled to the first frame body 2210 and the second frame body 2220.

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.

In an embodiment of the present invention, the immersed tube sinking device further includes a first pre-embedded component 6 and a second pre-embedded component 77; part of the structure of the first embedded assembly 6 is embedded in the pipe main body section 81, and the other part of the structure is detachably connected with the first frame 2210; part of the second embedded component 77 is embedded in the pipe connection section 82, and the other part of the second embedded component is detachably connected with the second frame 2220

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.

Referring to fig. 2 and fig. 3, in an embodiment of the present invention, the first pre-buried assembly 6 includes a first pre-buried rod 61, one end of the first pre-buried rod 61 is pre-buried in the pipe main body section 81, the other end is provided with a connection seat body 611, the connection seat body 611 is provided with a frame body installation slot 611a, and a movable frame body limiting member 6111 is disposed near the frame body installation slot 611 a; the first frame 2210 comprises a first frame body 2211 and a first upper support plate 2212, part of the structure of the first frame body 2211 is embedded in the frame mounting groove 611a, and a limit groove 2211a is disposed on the surface of the groove sidewall facing the frame mounting groove 611a, the frame stop 6111 moves relative to the connection base 611 and can be clamped in the limit groove 2211a to connect the first frame body 2211 to the connection base 611, and the first upper support plate 2212 is connected to one end of the first frame body 2211 away from the groove bottom wall of the frame mounting groove 611a and is connected to the inner side plate 231 and the outer side plate 232 of two frame side bases 230 that are disposed opposite to each other among the three frame side bases 230.

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. The arrangement of the first upper support plate 2212 increases the contact area between the first frame main body 2211 and the frame side base 230, so that the first frame main body 2211 can stably support the frame side base 230; meanwhile, the pressure loss of the surface of the frame side seat 230 due to stress concentration caused by an excessively small contact area between the first frame body 2210 and the frame side seat 230 is avoided, so that the safety of the first frame body 2210 and the frame side seat 230 in the abutting process can be improved. And the inner side plate 231 and the outer side plate 232 of the first upper support plate 2212 and the frame side seat 230 can be fixed by welding, so that the two can ensure the strength of the structure without setting a fixing structure, and the stability of the first upper support plate 2212 at the joint with the inner side plate 231 and the outer side plate 232 is ensured. Further, the first embedded assembly 6 further includes a first embedded plate 62, and the first embedded plate 62 is disposed at one end of the first embedded rod 61 far away from the first lower support plate, and is used for being embedded in the pipe main body section 81. The stability of the connection of the first embedment component 6 and the pipe main body section 81 can be improved by the first embedment plate 62.

In an embodiment of the invention, the connecting base 611 has one of a rotating shaft and a shaft hole, one end of the frame limiting member 6111 has the other of the rotating shaft and the shaft hole, and the rotating shaft is inserted into the shaft hole, so that the frame limiting member 6111 is rotatably connected to the connecting base 611.

It can be understood that the frame stop 6111 is rotatably connected to the connecting base 611, such that the moving path of the frame stop 6111 is curved, and the side circumference of the first frame main body 2211, which is provided with the stop groove 2211a, can be arranged in parallel. At this time, the installation of the frame body limiting part 6111 on the connection base 611 is compact, so that the occupied space is reduced, and the frame body limiting part 6111 is conveniently arranged in the limited space on the connection base 611. The matching of the rotation shaft and the shaft hole simplifies the rotation connection structure of the frame body limiting member 6111 and the connection base 611, thereby reducing the manufacturing cost. Wherein the shaft may be a damped shaft. In addition, it should be noted that, the present application is not limited to this, in other embodiments, the frame stopper 6111 may also be slidably connected to the connecting base 6111, and be driven by a spring to slide relative to the connecting base 611 to be clamped into the stopper groove 2211 a.

In an embodiment of the invention, a first magnetic block is embedded in a groove wall in the limiting groove 2211a, a second magnetic block is embedded in the frame limiting member 6111, and the second magnetic block and the first magnetic block are oppositely arranged and can be attracted to each other.

It can be understood that the first magnetic block and the second magnetic block are in adsorption fit, so that the frame body limiting part 6111 is adsorbed and limited in the limiting groove 2211a, and the possibility that the frame body limiting part 6111 is separated from the limiting groove 2211a is reduced, thereby further connecting the stability of the connection between the base body 611 and the first frame main body 2211. The first magnetic block and the second magnetic block are fixedly embedded, so that the first magnetic block and the second magnetic block can be installed compactly, and the occupation of an installation space is reduced.

In an embodiment of the present invention, the notch of the frame body installation groove 611a is disposed in a flaring shape.

It can be appreciated that the arrangement of the slot of the frame body mounting groove 611a guides the mounting of the first frame body 2211, and the first frame body 2211 can be guided to be accurately inserted into the frame body mounting groove 611a, so that the alignment accuracy of the first frame body 2210 and the sinking pipe 8 during connection is further reduced, and the convenience of connection between the first frame body 2210 and the sinking pipe 8 is improved.

Referring to fig. 2 and 4, in an embodiment of the present invention, the second embedded component 77 includes a second embedded rod 71 and a screwing nut 72, one end of the second embedded rod 71 is embedded in the pipe connecting section 82, and the screwing nut 72 is sleeved on the other end of the second embedded rod 71; the second frame body 2220 includes a second frame body 2221, a second upper support plate 2222 and a second lower support plate 2223, the second frame body 2221 has an upper end and a lower end which are oppositely arranged, the second upper support plate 2222 is connected to the upper end of the second frame body 2221 and is connected to the inner side plate 231 and the outer side plate 232 of the two frame side seats 230 which are oppositely arranged in the three frame side seats 230, the second lower support plate 2223 is provided with a screw mounting hole 2223a, one end of the second embedded rod 71 which is far away from the sinking tube 8 passes through the screw mounting hole 2223a, the screwing nut 72 abuts against one side of the second lower support plate 2223 which is far away from the sinking tube 8 and is matched with the sinking tube 8 to clamp and fix the second lower support plate 2223.

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. The second lower support plate 2223 is provided to facilitate the screw installation holes 2223a, and the contact area between the second frame body 2220 and the pipe connection section 82 is increased to improve the connection stability between the two. And the second upper support plate 2222 and the inner side plate 231 and the outer side plate 232 of the frame side seat 230 may be fixed by welding, so that they can ensure the strength of their own structure without providing a fixing structure, and at the same time, the stability of the second upper support plate 2222 and the inner side plate 231 and the outer side plate 232 at the joint is also ensured. 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. Of course, it should be noted that the present invention is not limited thereto, and in other embodiments, the first frame 2210 and the pipe main body segment 81 may be fixed by magnetic attraction, and the second frame 2220 and the pipe connecting segment 82 may be fixed by snap-fit.
