Description

Technical Field

[0001] The present invention relates to the field of marine survey equipment, and particularly to a long-endurance underwater observation device. Background Art

[0002] The patent document with the publication number of CN 117602042 B discloses a long-endurance underwater observation device, which includes a charging base, a mobile observation device, a winding mechanism, and a floating mechanism: The mobile observation device includes a frame and a power mechanism, an observation sensor assembly, a battery, and a wireless charging unit installed on the frame; The charging base includes a base body, a battery pack, and a support platform. The battery pack is arranged in the base body, the support platform is fixed above the base body, and a wireless charging component electrically connected to the battery pack is provided on the support platform; The winding mechanism is installed in the charging base. The winding mechanism has a winding disc, a rope wound around the winding disc, and a winding motor for driving the winding disc to rotate. One end of the rope is connected to the frame of the mobile observation device. When the winding motor winds, it can drive the mobile observation device to move to the support platform, so that the wireless charging unit of the mobile observation device corresponds to the wireless charging component. The battery pack of the charging base can charge the battery of the mobile observation device through the cooperation of the wireless charging component and the wireless charging unit.

[0003] The mobile observation device and the charging base are connected by the rope of the winding mechanism. The seabed environment is relatively complex. When the rope is wound around seamounts, rocks, animals and plants, or planktonic animals and plants on the seabed, it will affect the floating recovery of the observation device and cause losses. Summary of the Invention

[0004] The present invention aims at the above problems and provides a long-endurance underwater observation device.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A long-endurance underwater observation device includes a charging base, a mobile observation device, a winding mechanism, and a floating mechanism; the winding mechanism and the floating mechanism are arranged on the charging base. The winding mechanism includes a rope for connecting the mobile observation device. The charging base has a first through hole for the rope to pass through. The long-endurance underwater observation device further includes a cut-off floating control structure, and the cut-off floating control structure includes:

[0007] A first groove is arranged on the charging base, and one side of the first groove has a blade channel communicating with the first through hole;

[0008] A sliding block is slidably installed in the first groove. The sliding block has a cutting working position, an initial working position, and a floating working position;

[0009] A cutting blade is fixed on the sliding block and extends into the blade channel;

[0010] The floating control member is slidably mounted on the first groove. The floating control member and the cutting blade are respectively located on both sides of the sliding block. One end of the floating control member away from the sliding block is located at the floating mechanism and is used to drive the floating mechanism to open.

[0011] The first elastic member is arranged in the first groove and is used to make the floating control member have a movement tendency to approach the first through hole.

[0012] The electric push rod is installed on the seat body and is used to drive the sliding block to switch between the cutting working position, the initial working position and the floating working position. When the sliding block is in the initial working position, the cutting blade does not extend into the first through hole and the floating control member does not open the floating mechanism. When the sliding block is in the cutting working position, the cutting blade extends into the first through hole to cut the rope in the first through hole. When the sliding block is in the floating working position, the floating control member opens the floating mechanism.

[0013] Compared with the existing equipment, the present application adds a cutting and floating control structure. When the rope is wound around underwater mountains, rocks, animals, plants or plankton, etc., resulting in abnormal recovery of the rope, the electric push rod can switch the sliding block from the initial working position to the cutting working position, and the cutting blade cuts the rope in the first through hole, so that the rope entangled with foreign objects will not affect the floating of the subsequent charging base. Then the electric push rod rotates in the reverse direction and moves from the cutting working position to the floating working position, and the floating control member opens the floating mechanism to realize the floating operation.

[0014] The present application can perform two operations of cutting and floating mechanism control through the electric push rod, which is structurally compact compared with independently arranging two sets of moving elements.

[0015] When the rope is not wound, the normal floating operation is carried out by controlling the sliding block to switch from the initial working position to the floating working position.

[0016] In one embodiment of the present invention, the charging base includes a seat body and a battery pack. The battery pack is arranged in the seat body. The seat body has a support platform. The winding mechanism further has a winding disc and a winding motor for driving the winding disc to rotate. The rope is wound around the winding disc, and when the winding motor winds, it can drive the mobile observation device to move to the support platform.

[0017] The side wall of the charging female socket has a mounting groove, and the floating mechanism is arranged on the charging female socket. The floating mechanism includes: a floating block arranged at the notch of the mounting groove; a hollow pull tube with one end closed and the other end open. The hollow pull tube is wound and stored in the mounting groove, and the open end of the hollow pull tube is fixed to the socket body; a first airbag fixed on the hollow pull tube, adjacent to the closed end of the hollow pull tube, and the first airbag is communicated with the hollow pull tube; an inflation gas tank fixed in the socket body and communicated with the open end of the hollow pull tube; an electromagnetic valve arranged between the inflation gas tank and the hollow pull tube.

[0018] One end of the floating control member away from the sliding block is located in the mounting groove. When the sliding block is in the floating working position, when the floating control member moves towards the side away from the first through hole, the floating control member can eject the floating block of the floating mechanism from the mounting groove.

[0019] When the sliding block is in the floating working position, the floating control member can eject the floating block from the mounting groove. Under the action of the buoyancy of the floating block, the hollow pull tube can be quickly pulled upwards, and then the electromagnetic valve is opened. The high-pressure gas in the inflation gas tank moves along the hollow pull tube and finally enters the upper first airbag. The first airbag expands, generating enough buoyancy to drive the charging female socket to float. The charging female socket has a large-capacity battery pack and is relatively heavy, so the traditional floating structure is not applicable. Through the design of the floating block and the hollow pull tube in the floating mechanism of the present application, during recovery, the upper end of the hollow pull tube can have a relatively high distance from the seabed. The pressure on the first airbag adjacent to the closed end (upper end) of the hollow pull tube is relatively small, and the inflation gas tank can better inflate the first airbag. The first airbag can expand larger and generate enough buoyancy.

[0020] During actual operation, when the charging female socket determines according to the set conditions that the winding motor stops rotating and is overloaded and the mobile observation device cannot be normally recovered, the controller of the charging female socket controls to cut off the working of the floating control structure to cut off the rope.

[0021] In one embodiment of the present invention, one end of the floating control member away from the sliding block has a pushing block. The pushing block has a body slidably matched with the mounting groove and an extension column fixed to the body and extending towards the floating block side. The body has a hole for the hollow pull tube to pass through. The body, the mounting groove and the floating block form an accommodating space for accommodating the wound hollow pull tube. When the floating control member moves towards the side away from the first through hole, the extension column of the pushing block ejects the floating block from the mounting groove.

[0022] The side wall of the floating block has a locking hole.

[0023] The socket body also has a floating block locking structure, and the floating block locking structure includes:

[0024] A second groove is located on the side wall of the installation groove and at the groove opening, one side of the second groove has a second through hole, and the second groove is connected to the installation groove through the second through hole;

[0025] A wire-passing channel is located on the side wall of the mounting groove, one end of the wire-passing channel is connected to an end of the second groove away from the second through hole, and the other end of the wire-passing channel is located on a side of the mounting groove away from the notch and is connected to the second groove;

[0026] A locking pin is slidably mounted in the second groove, the locking pin having a locking portion passing through the second through hole for cooperating with the locking hole of the floating block;

[0027] A second elastic member is located in the second groove and is used to make the locking pin have a movement tendency to move toward one side of the second through hole;

[0028] A moving block is located in the accommodation space and on a side of the installation slot away from the slot opening;

[0029] A connecting wire is located in the wire passage, one end of the connecting wire is fixed to the moving block, and the other end of the connecting wire is fixed to the locking pin.

[0030] In the prior art, the floating block is not locked. In actual use, the floating block is easy to detach from the installation groove and float up, causing the hollow pull tube to be accidentally pulled out, which will affect the subsequent work, especially it is easy to cause the rope and the hollow pull tube to be entangled. The present application can lock the floating block by setting a floating block locking structure, effectively preventing the floating block from accidentally detaching. Through the design of the connecting line and the moving block, when the pushing block moves to one side of the floating block, it can first drive the moving block to move (the locking pin is unlocked by the connecting line when the moving block moves), and then the pushing block continues to move, and the unlocked floating block is pushed out of the installation groove through the extension column.

[0031] In one embodiment of the present invention, when the sliding block is in the initial working position, there is a gap between the extension column of the pushing block and the floating block. When the pushing block moves toward the side of the floating block until the extension column contacts the floating block, the body of the pushing block drives the moving block to move, and the moving block makes the locking part of the locking pin completely disengage from the locking hole of the floating block through the connecting line.

[0032] In one embodiment of the present invention, the moving block is an elastic member, or the connecting line is an elastic rope.

[0033] This arrangement can prevent the connecting wire from being broken.

[0034] In one embodiment of the present invention, one of the sidewalls of the second groove and the sidewalls of the floating block has a limiting protrusion, and the other has a limiting sliding groove, and the limiting protrusion and the limiting sliding groove are slidably matched.

[0035] In one embodiment of the present invention, the floating control member further includes a first member and a second member. The first member, the second member, and the pushing block are sequentially hinged, and the first member is slidably disposed on the first groove.

[0036] In one embodiment of the present invention, the floating mechanism further includes a second airbag fixed on the hollow pull tube. The second airbag is adjacent to the body, and the second airbag is communicated with the hollow pull tube.

[0037] The length of the hollow pull tube is relatively long. If the second airbag is not provided, when the seat body finally moves up to the maximum position, there is a certain distance from the sea surface, which is not convenient for salvaging the seat body. By providing the second airbag at a lower position of the hollow pull tube, the final position of the seat body can be closer to the sea surface, which is convenient for the salvaging operation of the seat body.

[0038] In one embodiment of the present invention, the blade channel is perpendicular to the first through hole.

[0039] In one embodiment of the present invention, there are multiple blade channels and cutting blades. The multiple blade channels and the multiple cutting blades are in one-to-one correspondence and cooperation.

[0040] In one embodiment of the present invention, the middle part of the support platform has a conical positioning hole, and the first through hole is communicated with the bottom wall of the conical positioning hole;

[0041] The mobile observation device further includes a floating component and a wireless communication unit disposed on the frame. The frame has a conical positioning block, and the conical positioning block is adapted to the conical positioning hole. The end of the rope sequentially passes through the first through hole and the conical positioning hole and then is connected to the conical positioning block;

[0042] One end of the rope cooperating with the mobile observation device is a ring structure, and the ring structure is formed with a jack;

[0043] The lower end surface of the conical positioning block has a third groove, and the side wall of the third groove has a shaft hole. A linear motor is also installed in the conical positioning block. The telescopic shaft of the linear motor can extend into the third groove or retract from the third groove. When the telescopic shaft of the linear motor extends into the third groove, the telescopic shaft can pass through the jack of the rope and then be inserted into the shaft hole.

[0044] When the charging female seat needs to cut off the rope, the charging female seat sends a signal to the mobile observation device through the communication unit. The mobile observation device first controls the telescopic shaft of the linear motor to retract from the third groove, and then controls the floating component to open for floating operation. That is, when the rope is wound, the charging female seat can be recovered by floating by cutting off the rope, and the mobile observation device can be recovered by floating by the telescopic shaft disengaging from the jack of the rope.

[0045] In one embodiment of the present invention, the floating component includes a high-pressure gas cylinder and a floating airbag. The floating airbag is connected to the high-pressure gas cylinder through a pipeline, and a control valve is installed on the pipeline.

[0046] The beneficial effects of the present invention are as follows: Compared with existing equipment, this application adds a cut-off floating control structure. When the rope is wound around underwater mountains, rocks, animals or plants, or plankton, etc., resulting in the inability to normally recover the rope, the electric push rod can switch the sliding block from the initial working position to the cut-off working position, and the cutting blade cuts the rope in the first through hole, so that the rope entangled with foreign objects will not affect the floating of the subsequent charging base. Then the electric push rod rotates in the reverse direction and moves from the cut-off working position to the floating working position. The floating control member ejects the floating block of the floating mechanism from the installation groove. Under the action of the buoyancy of the floating block, the hollow pull pipe can be quickly pulled upward. Then the electromagnetic valve is opened, and the high-pressure gas in the inflatable gas cylinder moves along the hollow pull pipe and finally enters the upper first airbag. The first airbag expands, generating sufficient buoyancy to drive the charging base to float. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0062] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0063] As Figures 1 to 10 shown, a long-endurance underwater observation device is disclosed. As Figure 1 , Figure 2 and Figure 4 shown, the long-endurance underwater observation device includes a charging base 1, a mobile observation device 2, a winding mechanism 3, and a floating mechanism 4; the charging base 1 includes a base body 11 and a battery pack (not shown in the figure), the battery pack is disposed in the base body 11, the base body 11 has a support platform 112, the winding mechanism 3 is installed in the charging base 1, the winding mechanism 3 has a winding disc 31, a rope 32 wound around the winding disc 31, and a winding motor 33 for driving the winding disc 31 to rotate. One end of the rope 32 is connected to the mobile observation device 2, and when the winding motor 33 winds, it can drive the mobile observation device 2 to move onto the support platform 112;

[0064] As Figure 2 , Figure 4 and Figure 6 shown, the side wall of the charging base 1 has an installation groove 111, the floating mechanism 4 is disposed on the charging base 1, and the floating mechanism 4 includes: a floating block 41 disposed at the notch of the installation groove 111; a hollow pull tube 42 with one end closed and one end open, the hollow pull tube 42 is wound and stored in the installation groove 111, and the open end of the hollow pull tube 42 is fixed to the base body 11; a first airbag 43 fixed on the hollow pull tube 42, adjacent to the closed end of the hollow pull tube 42, and the first airbag 43 is communicated with the hollow pull tube 42; an inflation gas tank 45 fixed in the base body 11 and communicated with the open end of the hollow pull tube 42; an electric control valve 46 disposed between the inflation gas tank 45 and the hollow pull tube 42;

[0065] As Figure 5 shown, the base body 11 has a first through hole 113 for the rope 32 to pass through, and the long-endurance underwater observation device further includes a cut-off floating control structure. As Figure 4 and Figure 5 shown, the cut-off floating control structure includes:

[0066] a first groove 51 provided on the base body 11;

[0067] a blade channel 52 perpendicular to the first through hole 113, one end of the blade channel 52 is communicated with the first through hole 113, and the other end is communicated with the first groove 51;

[0068] a sliding block 53 slidably installed in the first groove 51, and the sliding block 53 has a cutting working position, an initial working position, and a floating working position;

[0069] a cutting blade 54 fixed on the sliding block 53 and extending into the blade channel 52;

[0070] The floating control member 55 is slidably mounted on the first groove 51. The floating control member 55 and the cutting blade 54 are respectively located on both sides of the sliding block 53. One end of the floating control member 55 away from the sliding block 53 is located in the mounting groove 111. When the floating control member 55 moves towards the side away from the first through hole 113, the floating control member 55 can eject the floating block 41 of the floating mechanism 4 from the mounting groove 111.

[0071] The first elastic member 56 is arranged in the first groove 51 and is used to make the floating control member 55 have a movement tendency to approach the first through hole 113.

[0072] The electric push rod 57 is mounted on the seat body 11 and is used to drive the sliding block 53 to switch between the cutting working position, the initial working position and the floating working position. When the sliding block 53 is in the initial working position, the cutting blade 54 does not extend into the first through hole 113 and the floating control member 55 does not eject the floating block 41 of the floating mechanism 4 from the mounting groove 111. When the sliding block 53 is in the cutting working position, the cutting blade 54 extends into the first through hole 113 to cut off the rope 32 in the first through hole 113. When the sliding block 53 is in the floating working position, the floating control member 55 ejects the floating block 41 of the floating mechanism 4 from the mounting groove 111.

[0073] Compared with the existing equipment, the present application adds a cutting and floating control structure. When the rope 32 is wound around underwater mountains, rocks, animals and plants or plankton, etc., resulting in the abnormal recovery of the rope 32, the electric push rod 57 can switch the sliding block 53 from the initial working position to the cutting working position, and the cutting blade 54 cuts off the rope 32 in the first through hole 113, so that the rope 32 entangled with foreign objects will not affect the floating of the subsequent charging base 1. Then the electric push rod 57 rotates reversely and moves from the cutting working position to the floating working position (see Figure 8 、 Figure 9 and Figure 10 ), the floating control member 55 ejects the floating block 41 of the floating mechanism 4 from the mounting groove 111. Under the buoyancy of the floating block 41, the hollow pull tube 42 can be quickly pulled upward. Then the electromagnetic valve 46 is opened, and the high-pressure gas in the inflatable gas tank 45 moves along the hollow pull tube 42 and finally enters the first airbag 43 above. The first airbag 43 expands to generate enough buoyancy to drive the charging base 1 to float.

[0074] When the rope 32 is not wound, the normal floating operation is carried out by controlling the sliding block 53 to switch from the initial working position to the floating working position.

[0075] Since the charging socket 1 has a large-capacity battery pack and is heavy, the traditional floating structure is not applicable. Through the design of the floating block 41 and the hollow pull tube 42, the floating mechanism 4 of the present application can keep the upper end of the hollow pull tube 42 at a relatively high distance from the seabed during recovery. The pressure on the first airbag 43 near the closed end (upper end) of the hollow pull tube 42 is small, and the inflation gas tank 45 can better inflate the first airbag 43. The first airbag 43 can expand to a larger size and generate sufficient buoyancy.

[0076] During actual operation, when the charging socket 1 determines according to the set conditions that the winding motor 33 stalls or overloads and the mobile observation device 2 cannot be normally retracted, the controller of the charging socket 1 controls to cut off the floating control structure to cut off the rope 32.

[0077] The present application can perform two operations of cutting off and controlling the floating mechanism 4 through the electric push rod 57, which is more compact compared to independently arranging two sets of moving components.

[0078] Such as Figure 4 、 Figure 6 、 Figure 8 and Figure 10 As shown in the figures, in this embodiment, one end of the floating control member 55 away from the sliding block 53 has a pushing block 551. The pushing block 551 has a main body 5511 that is slidably engaged with the installation groove 111 and an extension column 5512 that is fixed to the main body 5511 and extends toward the floating block 41. The main body 5511 has a hole for the hollow pull tube 42 to pass through. The main body 5511, the installation groove 111 and the floating block 41 form an accommodation space 7 for accommodating the wound hollow pull tube 42. When the floating control member 55 moves toward the side away from the first through hole 113, the extension column 5512 of the pushing block 551 pushes the floating block 41 out of the installation groove 111.

[0079] Such as Figure 6 and Figure 10 As shown in the figures, the side wall of the floating block 41 has a locking hole 411.

[0080] Such as Figure 6 and Figure 10 As shown in the figures, the seat body 11 also has a floating block 41 locking structure, which includes:

[0081] A second groove 61, located on the side wall of the installation groove 111 and at the notch position. One side of the second groove 61 has a second through hole 62, and the second groove 61 communicates with the installation groove 111 through the second through hole 62.

[0082] A wire passing channel 63, located on the side wall of the installation groove 111. One end of the wire passing channel 63 communicates with the end of the second groove 61 away from the second through hole 62, and the other end of the wire passing channel 63 is located on the side of the installation groove 111 away from the notch and communicates with the second groove 61.

[0083] The locking pin 64 is slidably installed in the second groove 61. The locking pin 64 has a locking portion 641 that passes through the second through hole 62 for mating with the locking hole 411 of the floating block 41.

[0084] The second elastic member 65 is located in the second groove 61 and is used to make the locking pin 64 have a tendency to move toward the side of the second through hole 62.

[0085] The moving block 66 is located in the accommodation space 7 and on the side of the mounting groove 111 away from the notch.

[0086] The connecting line 67 is located in the wire passing channel 63. One end of the connecting line 67 is fixed to the moving block 66, and the other end is fixed to the locking pin 64.

[0087] In the prior art, the floating block 41 is not locked. During actual use, the floating block 41 is likely to disengage and float upward from the mounting groove 111, resulting in the accidental pulling out of the hollow drawing tube 42, which will affect the subsequent work. In particular, it is likely to cause entanglement of the rope 32 and the hollow drawing tube 42. In this application, by providing a locking structure for the floating block 41, the floating block 41 can be locked tightly, effectively preventing the accidental disengagement of the floating block 41. Through the design of the connecting line 67 and the moving block 66, when the pushing block 551 moves toward the floating block 41, it can first drive the moving block 66 to move (when the moving block 66 moves, the locking pin 64 is unlocked through the connecting line 67), and then the pushing block 551 continues to move, and the unlocked floating block 41 is pushed out of the mounting groove 111 through the extension post 5512.

[0088] As Figure 6 shown, in this embodiment, when the sliding block 53 is in the initial working position, there is a gap between the extension post 5512 of the pushing block 551 and the floating block 41. When the pushing block 551 moves toward the floating block 41 until the extension post 5512 contacts the floating block 41, the body 5511 of the pushing block 551 drives the moving block 66 to move, and the moving block 66 makes the locking portion 641 of the locking pin 64 completely disengage from the locking hole 411 of the floating block 41 through the connecting line 67.

[0089] In this embodiment, the moving block 66 is an elastic member, or the connecting line 67 is an elastic rope. Such a setting can prevent the connecting line 67 from being broken.

[0090] As Figure 6 and Figure 10 shown, in this embodiment, among the side walls of the second groove 61 and the side wall of the floating block 41, one has a limiting convex block 412, and the other has a limiting sliding groove 1111, and the limiting convex block 412 and the limiting sliding groove 1111 are in sliding limiting cooperation.

[0091] As Figure 4 、 Figure 6 、Figure 8 and Figure 10 As shown in Figure 10 , in this embodiment, the floating control member 55 further includes a first member 552 and a second member 553. The first member 552, the second member 553 and the pushing block 551 are sequentially hinged, and the first member 552 is slidably disposed on the first groove 51.

[0092] As Figure 2 , Figure 6 and Figure 10 As shown in Figure 6 and Figure 10 , in this embodiment, the floating mechanism 4 further includes a second airbag 44 fixed on the hollow pull tube 42. The second airbag 44 is adjacent to the main body 5511, and the second airbag 44 is communicated with the hollow pull tube 42.

[0093] The length of the hollow pull tube 42 is relatively long. If the second airbag 44 is not provided, when the final seat body 11 moves up to the maximum position, there is a certain distance from the sea surface, which is not convenient for salvaging the seat body 11; by providing the second airbag 44 at a lower position of the hollow pull tube 42, the final position of the seat body 11 can be closer to the sea surface, which is convenient for the salvaging operation of the seat body 11.

[0094] As Figure 5 As shown in Figure 5 , in this embodiment, there are a plurality of blade channels 52 and cutting blades 54, and the plurality of blade channels 52 and the plurality of cutting blades 54 are in one-to-one correspondence and cooperation.

[0095] As Figure 1 , Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , in this embodiment, the middle part of the support platform 112 has a conical positioning hole 114, and the first through hole 113 is communicated with the bottom wall of the conical positioning hole 114;

[0096] The mobile observation device 2 further includes a floating component (not shown in the figure) and a wireless communication unit (not shown in the figure) provided on the frame. As Figure 1 , Figure 4 and Figure 7 As shown in Figure 4 and Figure 7 , the frame has a conical positioning block 21, the conical positioning block 21 is adapted to the conical positioning hole 114, and the end of the rope 32 sequentially passes through the first through hole 113 and the conical positioning hole 114 and then is connected to the conical positioning block 21;

[0097] One end of the rope 32 cooperating with the mobile observation device 2 is a ring structure, and the ring structure is formed with a jack;

[0098] As Figure 7As shown, the lower end surface of the conical positioning block 21 has a third groove 211, and a shaft hole 212 is provided on the side wall of the third groove 211. A linear motor 213 is also installed inside the conical positioning block 21. The telescopic shaft 214 of the linear motor 213 can extend into or retract from the third groove 211. When the telescopic shaft 214 of the linear motor 213 extends into the third groove 211, the telescopic shaft 214 can pass through the insertion hole of the rope 32 and then be inserted into the shaft hole 212.

[0099] When the charging female base 1 needs to cut off the rope 32, the charging female base 1 sends a signal to the mobile observation device 2 through the communication unit. The mobile observation device 2 first controls the telescopic shaft 214 of the linear motor 213 to retract from the third groove 211, and then controls the floating component to open for floating operation. That is, when the rope 32 is wound, the floating and recovery of the charging female base 1 can be realized by cutting off the rope 32, and the floating and recovery of the mobile observation device 2 can be realized by the telescopic shaft 214 disengaging from the insertion hole of the rope 32.

[0100] In actual use, the floating component can adopt a conventional floating mechanism, such as including a high-pressure gas cylinder and a floating airbag. The floating airbag is connected to the high-pressure gas cylinder through a pipeline, and a control valve is installed on the pipeline.

[0101] The above are only the preferred embodiments of the present invention, and thus do not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, directly or indirectly applied in other related technical fields, shall be included in the protection scope of the present invention by the same token.
