Description

Technical Field

[0001] The invention relates to the technical field of submarine pipeline management, and in particular to a sand throwing guide device for the management of exposed submarine pipelines. Background Art

[0002] With the rapid development of social economy, the demand for oil resources is increasing, while the land oil resources are decreasing. Continuously increasing the intensity of offshore oil development and strengthening the protection of submarine pipelines have also become an important part of marine production operations. Under the influence of different marine environments such as water flow, submarine pipelines are exposed and suspended. If they are not treated in time, it will seriously affect marine operations and even affect the safety of the marine ecological environment. At present, the main methods for the treatment of suspended submarine pipelines are sandbag covering method, steel structure support method, bionic grass laying method and riprap landfill method. At present, the sandbag covering method is mainly used, which has the advantages of simple operation and significant effect. Sandbags are mainly composed of sea sand and cement. During the construction process, sandbags are thrown into the seawater. Due to the movement of water flow, the sandbags cannot accurately reach the construction area, which not only causes a waste of resources, but also increases the working time and workload of divers to adjust the position of sandbags. When covering with sandbags, it is necessary to locate the submarine pipeline. The absolute position of the exposed submarine pipeline in the suspended section is known. In the prior art, two receivers are usually placed on the ship to locate the position of the ship. The operator needs to move the hull and the sand throwing port by calculation based on the data obtained by the receiver, the known absolute position of the exposed submarine pipeline in the suspended section, and the setting of the sand throwing port, and then throw sand. Since the position of the sand throwing port cannot be directly located, there is a large error. Summary of the invention

[0003] In view of the shortcomings of the background technology, the present invention provides a sand throwing guide device for the exposed management of submarine pipelines, which can directly locate the position of the sand throwing port, improve the accuracy of the sand throwing operation, and reduce the waste of sand bags.

[0004] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a sand throwing guide device for the treatment of exposed submarine pipelines, comprising a hull, the hull is connected to a conveyor belt through a first support rod and a second support rod, a fixing rod is arranged between the first support rod and the second support rod, the fixing rod is detachably connected to a limiting assembly through a supporting mechanism, a Beidou navigation positioning system receiver receiving signal head is arranged on the supporting mechanism, a guiding net is connected to the limiting assembly, and a second supporting ring and a third supporting ring are arranged on the guiding net;

[0005] The third support ring is arranged at the bottom of the guide net, and the guide net is connected to the third support ring through a third fixing ring. The bottom of the third support ring is fixedly connected with a connecting ring, and the connecting ring is connected to a limiting ring through a threaded structure. A counterweight ring is arranged between the third support ring and the limiting ring.

[0006] By adopting the above scheme, a Beidou navigation and positioning system receiver is arranged on the supporting mechanism, and a receiving signal head can locate the position of the supporting mechanism, which is convenient for accurate sand throwing. The sandbag is placed on the conveyor belt, and the sandbag can move with the conveyor belt, and then pass through the limiting assembly and the supporting mechanism to fall into the guide net, and under the guidance of the guide net, the sandbag is thrown out from the counterweight ring and the connecting ring, so as to accurately fall on the exposed submarine pipeline, thereby improving the accuracy of the sand throwing operation and reducing the waste of sandbags. The supporting mechanism is used to support the limiting assembly, and the second supporting ring and the third supporting ring can support the guide net to prevent the guide net from being entangled and affecting the movement of the sandbag inside the guide net. The counterweight ring makes the guide net vertically downward to prevent the guide net from tilting and affecting the accuracy of sand throwing. The supporting mechanism and the limiting assembly are detachably connected, and the counterweight ring and the connecting ring are detachably connected, which is convenient for disassembly and assembly. The limiting ring can be removed from the connecting ring to facilitate the replacement of the counterweight ring.

[0007] Preferably, the supporting mechanism includes a first supporting plate, the first supporting plate is fixedly connected to the fixing rod, a second supporting plate is fixedly connected to the first supporting plate, a limiting column and a threaded hole are arranged on the second supporting plate, and a receiving signal head of the Beidou navigation and positioning system receiver is installed on the second supporting plate.

[0008] By adopting the above scheme, the absolute position coordinates of the exposed submarine pipeline in the suspended section are known, and the position of the second support plate is the position of the sand throwing port. Therefore, the Beidou navigation and positioning system receiver receiving signal head arranged on the second support plate can locate the position of the sand throwing port. The Beidou navigation and positioning system receiver is connected to the deck unit control room through a data cable. The position coordinates of the sand throwing port located by the Beidou navigation and positioning system receiver receiving signal head are dynamically displayed through the deck unit. Then the captain moves the hull according to the absolute position coordinates of the exposed submarine pipeline in the suspended section and the position coordinates of the sand throwing port, so that the sand throwing port is at the top of the submarine pipeline, thereby performing precise sand throwing. The model of the Beidou navigation and positioning system receiver is Hemisphere R330, which adopts the satellite station differential mode to directly locate the position of the sand throwing port, so that the accuracy of sand throwing reaches 0.1m.

[0009] Preferably, the second supporting plate is annular.

[0010] Preferably, the maximum diameter of the connecting ring is smaller than the inner ring diameter of the second supporting plate.

[0013] By adopting the above scheme, when the limit assembly and the support mechanism are installed, the limit column is inserted into the limit hole, so that the limit assembly and the support mechanism are initially fixed. The bottom of the limit rod is provided with an external thread compatible with the threaded hole. The limit rod is pressed downward to make the bottom of the limit rod contact with the threaded hole. The limit rod is turned to screw the bottom of the limit rod into the inside of the threaded hole, so that the limit assembly and the support mechanism are fixed. At this time, the spring is compressed, giving the limit rod an upward force, which can prevent the limit rod from loosening during the sand blasting process and improve the stability of the fixation of the limit assembly and the support mechanism. When disassembling, the limit rod is turned to disengage the limit rod from the threaded hole, and the limit assembly and the support mechanism can be disassembled. The installation and disassembly are simple and convenient.

[0014] Preferably, the first support ring, the second support ring and the third support ring are arranged at equal intervals.

[0015] By adopting the above solution, the first support ring, the second support ring and the third support ring can tighten the guide net, which is beneficial for the sandbags to pass through.

[0016] Preferably, the width of the conveyor belt is smaller than the inner ring diameter of the first supporting ring.

[0017] The above solution ensures that the sandbags transported by the transmission belt can pass through the first support ring.

[0018] Preferably, the guide net is connected to the second support ring via a second fixing ring.

[0019] By adopting the above solution, a plurality of second fixing rings are provided, and the guide net is partially wound around the second fixing rings, so that the guide net is stretched out by the second supporting ring.

The sandbags can move with the conveyor belt and then fall into the guide net through the limit assembly and the support mechanism. Under the guidance of the guide net, the sandbags are thrown out from the counterweight ring and the connecting ring, so that they accurately fall on the exposed submarine pipeline, thereby improving the accuracy of the sand throwing operation and reducing the waste of sandbags.

[0039] The absolute position coordinates of the exposed submarine pipeline in the suspended section are known, and the position of the second support plate 52 is the position of the sand throwing port. Therefore, the Beidou navigation and positioning system receiver receiving signal head 15 arranged on the second support plate 52 can locate the position of the sand throwing port. The Beidou navigation and positioning system receiver is connected to the deck unit control room through a data cable. The position coordinates of the sand throwing port located by the Beidou navigation and positioning system receiver receiving signal head 15 are dynamically displayed through the deck unit. Then the captain moves the hull according to the absolute position coordinates of the exposed submarine pipeline in the suspended section and the position coordinates of the sand throwing port, so that the sand throwing port is at the top of the submarine pipeline, thereby performing precise sand throwing. The model of the Beidou navigation and positioning system receiver is HemisphereR330, which adopts the satellite station differential mode to directly locate the position of the sand throwing port, so that the accuracy of sand throwing reaches 0.1m.

[0040] The second support plate 52 is annular, and the maximum diameter of the connecting ring 14 is smaller than the inner ring diameter of the second support plate 52 , so as to ensure that the connecting ring 14 can pass through the second support plate 52 .

A limiting rod 43 is slidably connected to the second limiting plate 47, and a spring 46 is passed through the limiting rod 43. One end of the spring 46 is fixedly connected to the second limiting plate 47, and the other end is fixedly connected to the limiting rod 43. A limiting block 48 is fixedly connected to the limiting rod 43.

[0042] When installing the limit assembly 4 and the support mechanism 5, the limit column 53 is inserted into the limit hole 42, so that the limit assembly 4 and the support mechanism 5 are initially fixed. The bottom of the limit rod 43 is provided with an external thread compatible with the threaded hole 54. The limit rod 43 is pressed downward to make the bottom of the limit rod 43 contact with the threaded hole 54, and the limit rod 43 is turned to screw the bottom of the limit rod 43 into the inside of the threaded hole 54, so that the limit assembly 4 and the support mechanism 5 are fixed. At this time, the spring 46 is compressed, giving the limit rod 43 an upward force, which can prevent the limit rod 43 from loosening during the sand blasting process and improve the stability of the fixation of the limit assembly 4 and the support mechanism 5. When disassembling, the limit rod 43 is turned to disengage the limit rod 43 from the threaded hole 54, so that the limit assembly 4 and the support mechanism 5 can be disassembled.

[0046] The inner ring diameter of the connecting ring 14 is not less than the inner ring diameter of the third supporting ring 13 to avoid affecting the throwing of the sandbag 3.

[0047] The guide net 6 is made of nylon.

[0048] Usage process: pass the connecting ring 14 and the counterweight ring 8 through the second support plate 52, and then insert the limiting column 53 into the limiting hole 42, so as to preliminarily fix the limiting assembly 4 and the supporting mechanism 5, press the limiting rod 43 downward to make the bottom of the limiting rod 43 contact with the threaded hole 54, twist the limiting rod 43, and screw the bottom of the limiting rod 43 into the inside of the threaded hole 54, so as to fix the limiting assembly 4 and the supporting mechanism 5. At this time, the spring 46 is compressed, giving the limiting rod 43 an upward force, which can prevent the limiting rod 43 from loosening during the sand throwing process, and improve the stability of the fixing of the limiting assembly 4 and the supporting mechanism 5. When disassembling, twist the limiting rod 43 to make the limiting rod 43 disengage from the threaded hole 54, so that the limiting assembly 4 and the supporting mechanism 5 can be disassembled, and the installation and disassembly are simple and convenient;

[0049] When sand throwing is being performed, the Beidou navigation and positioning system receiver receiving signal head 15 arranged on the second support plate 52 can locate the position of the sand throwing port. The Beidou navigation and positioning system receiver is connected to the deck unit control room via a data cable, and the position coordinates of the sand throwing port located by the Beidou navigation and positioning system receiver receiving signal head 15 are dynamically displayed through the deck unit. Then, the captain moves the hull according to the known absolute position coordinates of the exposed submarine pipeline in the suspended section and the position coordinates of the sand throwing port, so that the sand throwing port is at the top of the submarine pipeline, and then places the sandbag 3 on the conveyor belt 2. The sandbag 3 moves with the conveyor belt 2, and then passes through the limit assembly 4 and the support mechanism 5 and falls into the guide net 6. Under the guidance of the guide net 6, the sandbag 3 is thrown out from the counterweight ring 8 and the connecting ring 14, so as to accurately fall on the exposed submarine pipeline, thereby improving the accuracy of the sand throwing operation and reducing the waste of the sandbag 3.

[0050] The support mechanism 5 is used to support the limit assembly 4. The second support ring 7 and the third support ring 13 can support the guide net 6 to prevent the guide net 6 from being entangled and affecting the movement of the sandbag 3 inside the guide net 6. The counterweight ring 8 makes the guide net 6 vertically downward to prevent the guide net 6 from tilting and affecting the accuracy of sand throwing. The counterweight ring 8 is detachably connected to the connecting ring 14 and is easy to disassemble and assemble. The limit ring 9 can be removed from the connecting ring 14. After replacing the counterweight ring 8, the limit ring 9 and the connecting ring 14 can be assembled.
