Description

Technical Field

[0001] The present invention relates to the technical field of bird repelling for marine structures, and particularly to a bird repelling water cannon for marine platforms and an application method thereof. Background Art

[0002] With the development of marine resources, the number of marine platforms such as drilling platforms, wind power step-up platforms, and experimental platforms is increasing continuously. As large marine structures, marine platforms often become gathering places for flocks of birds, which will seriously interfere with the safety of the operating personnel on the marine platforms, especially the takeoff and landing of helicopters, and are greatly affected by the bird situation. Moreover, after the excrement of birds accumulates on the marine platform, it will also cause corrosion of the platform structure and affect the operation safety.

[0003] In current bird repelling technologies, gas guns, firecrackers, and titanium thunder guns are commonly used on land. Among them, gas guns need to change gas frequently, and titanium thunder guns and firecrackers need to change shells frequently. In the case of omnidirectional sound wave bird repelling, the sound is very similar to the siren when a ship is sailing. Although it can repel birds, it will also affect the operating personnel on the marine platform and the people living nearby. Therefore, a new bird repelling method is needed.

[0004] Considering the characteristics of the marine environment and the disadvantages of the existing technologies, using water to repel birds has become the best choice. The existing utility model patent with the authorized announcement number CN205431763U discloses a water spraying bird repelling device. In its technical solution, water is pumped by a water pump, and the water flows through the water outlet pipe to the nozzle and is then sprayed by the nozzle to repel birds.

[0005] However, in the above-mentioned scheme, the bending of the water pipe used will affect the water flow velocity, and the nozzle is horizontally arranged, which is not suitable for bird repelling operations over a vast sea area. It can be seen that in the current water spraying bird repelling devices, the relevant problems of the water spraying lift and the spraying structure applicable to marine bird repelling in the devices using water to repel birds have not been considered.

[0041] On the other hand, the present invention provides an application method of the above-mentioned bird repelling water cannon for an offshore platform, including the following steps:

[0042] S1. Fix the bird repelling water cannon for the offshore platform of the present invention to the offshore platform through an outer support, and connect the water inlet pipe to a seawater pump;

[0043] S2. Adjust the solenoid valve to the closed state and ensure that the solenoid valve is normally closed;

[0044] S3. Detect the bird situation through a bird detection radar. When a bird situation is found in the bird repelling operation area, the solenoid valve is opened;

[0045] S4. The immersion pump works to send high-pressure water flow into the main pipe. The high-pressure water flow is sprayed out after passing through the rear seat pipe and the water outlet cannon pipe in sequence to drive away the bird flock;

[0046] S5. Supply water from the seawater pump to the water storage tank through the water inlet pipe to ensure the water source.

[0047] The bird repelling water cannon for the offshore platform and the application method of the present invention have the following beneficial effects compared with the prior art:

[0048] (1) The water supply mechanism is used to supply water to the main pipe. The water outlet cannon pipe is connected to the main pipe through the rear seat pipe and the solenoid valve. The rear seat pipe adopts an arc-shaped structure, and the water outlet cannon pipe is provided with an arc angle; thus, through the cooperation of the rear seat pipe and the water outlet cannon pipe, the flow channel transition from the main pipe to the water outlet cannon pipe is smooth, which can ensure the spray head height; and this structural layout simplifies the pipeline structure, reduces the pipeline space occupation, and can prevent excessive occupation of the space of the offshore platform;

[0049] (2) In the X-Z plane, the arc angle corresponds to the axis of the solenoid valve, which can avoid excessive space occupation of the rear seat pipe and the water outlet cannon pipe in the radial direction of the main pipe, and is beneficial to ensuring the compactness of the structure; and in the Z-Y plane, the extension line of the water spraying direction of the water outlet cannon pipe intersects with the axis of the main pipe; this makes the water spraying direction inclined, which can increase the bird repelling range; and there are multiple solenoid valves, rear seat pipes and water outlet cannon pipes, which can further increase the bird repelling range and eliminate the bird repelling blind area;

[0050] (3) A flow dividing plate is arranged between the conduit and the nozzle of the water outlet cannon pipe, which can divide the water flow into thinner water columns, improve the water pressure, increase the spray head height, and avoid accidentally hurting birds, which is beneficial to ecological protection;

[0051] (4) In this bird - repelling water cannon, a submerged pump is used for water supply. The outlet pipe penetrates through the water storage tank and is connected to the outlet end of the submerged pump. The inlet pipe of the submerged pump is connected to the inner support in the outlet pipe. In this way, the submerged pump and the water storage tank form an integrated structure, which can avoid vibration during operation. At the same time, due to the structural design of the four inner supports, it will not affect the water pumping work of the submerged pump, ensuring the stability of application.

[0052] (5) In the water storage tank structure of this bird - repelling cannon, a spoiler is provided, which is used to separate the internal space of the water storage tank to separate the inlet pipe from the submerged pump. This enables the water supply mechanism to supply water to the water storage tank through the inlet pipe during the operation of the submerged pump in this bird - repelling cannon. The water flow can only overflow from the first chamber into the second chamber through the through - holes of the spoiler. Therefore, the water body fluctuation mainly occurs in the first chamber, avoiding the problem that the submerged pump cannot draw enough water flow due to water body fluctuation caused by water supply during the working process, thus ensuring the application effect.

[0053] (6) The end of the water storage tank is of a hemispherical structure, and a buffer frame is arranged in the water storage tank. The buffer frame can rely on the cross - plate to guide the water flow to the hemispherical wall surface at the end of the water storage tank, thereby reducing the impact force of the water flow entering the water storage tank through the inlet pipe, reducing the water body fluctuation, and avoiding affecting the water pumping of the submerged pump.

[0070] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0071] Such as Figures 1 to 14As shown, the bird-repelling water cannon for offshore platforms of the present invention comprises a water supply mechanism 1, a main pipe 2, a solenoid valve 3, a rear seat pipe 4, a water outlet cannon pipe 5, a connecting pipe 6, a rib plate 7, a side plate 8 and a buffer frame 9.

[0072] like Figures 1 to 6 As shown, the water supply mechanism 1 is used to provide water; the main pipe 2 is arranged along the Y axis, the main pipe 2 is connected to the water supply mechanism 1, and the main pipe 2 is used to output water flow;

[0073] As described above, the bird-repelling water cannon is used in an offshore platform. When the water supply mechanism 1 draws water, it can be directly connected to the seawater, and then the seawater is transported to the main pipe 2.

[0074] Specifically, the seawater pump provided by the offshore platform can be connected to the water supply mechanism 1 .

[0075] The electromagnetic valve 3 is arranged along the X axis, and one end of the electromagnetic valve 3 is connected to the main pipe 2; the electromagnetic valve 3 is used to control the on-off of the water flow supplied by the main pipe 2. Specifically, since the bird-repelling water cannon has multiple electromagnetic valves 3, their directions are different, here refers to the attached Figure 3 A solenoid valve 3 is indicated by a reference numeral.

[0076] One end of the rear seat tube 4 is connected and penetrated with the other end of the solenoid valve 3. The rear seat tube 4 is in an arc-shaped structure, and the other end thereof extends in a direction away from the water supply mechanism 1. The water outlet gun tube 5 is connected with the end of the rear seat tube 4 away from the solenoid valve 3.

[0077] As in the above structure, after the water flows through the main pipe 2 to the solenoid valve 3, when the solenoid valve 3 is in an open state, the water will enter the rear seat pipe 4, and then can be sprayed out through the water outlet cannon tube 5 to scare and drive away the birds.

[0078] like Figure 1 , Figure 3 and Figure 7 As shown, the water outlet gun tube 5 has an arc angle 501, and in the XZ plane, the arc angle 501 corresponds to the axis of the electromagnetic valve 3;

[0079] As the above structure, combined Figure 3 As shown, the rear seat pipe 4 is arc-shaped, and the water outlet cannon pipe 5 has an arc angle 501. Through the arrangement of this structure, the flow channel from the main pipe 2 to the water outlet cannon pipe 5 is smoothly transitioned, which can ensure smooth water flow to ensure the head. The design of the arc pipeline can also appropriately reduce the impact force of the water spray, and avoid excessive impact force to accidentally injure birds while ensuring the head range.

[0080] At the same time, the arc angle 501 in the XZ plane corresponds to the axis of the electromagnetic valve 3, which can prevent the rear seat tube 4 and the water outlet gun tube 5 from occupying too much space in the radial direction of the main tube 2, which is conducive to ensuring the compactness of the structure.

[0081] As Figure 2 shown, in the Z-Y plane, the extension line of the water spraying direction of the water outlet gun barrel 5 intersects with the axis of the main pipe 2.

[0082] With the above structure set, this makes the water spraying direction inclined, which can improve the bird repelling range. Compared with the unidirectional spraying water flow, it has a better bird repelling effect.

[0083] Furthermore, a plurality of electromagnetic valves 3 are provided, and the plurality of electromagnetic valves 3 are arranged in a circular array with the axis of the main pipe 2 as the reference, and each electromagnetic valve 3 is connected with a rear seat pipe 4 and a water outlet gun barrel 5; the plurality of water outlet gun barrels 5 are evenly arranged in a scattered manner in the X-Z plane.

[0084] With the above structure, a plurality of electromagnetic valves 3, rear seat pipes 4 and water outlet gun barrels 5 are provided, which can further improve the bird repelling range and eliminate the bird repelling blind area. Since the arc angle 501 of the water outlet gun barrel 5 in the X-Z plane corresponds to the axis of the electromagnetic valve 3, and with the cooperation of the arc-shaped rear seat pipe 4, the required layout space for each group of electromagnetic valves 3, rear seat pipes 4 and water outlet gun barrels 5 is very small, which can make the layout structure of multiple groups of electromagnetic valves 3, rear seat pipes 4 and water outlet gun barrels 5 compact, so as to avoid occupying too much area of the offshore platform.

[0085] Specifically in application, the plurality of water outlet gun barrels 5 can work together, or one or several can cooperate to carry out bird repelling work, and individual control can be carried out through the electromagnetic valve 3.

[0086] This bird repelling water cannon is used in cooperation with a bird detection radar. When a bird situation is detected, the radar control center gives the bird situation azimuth and approximate distance. The bird repelling water cannon opens the electromagnetic valve 3 corresponding to the bird situation azimuth according to the bird situation azimuth, so that the water outlet gun barrel 5 in that azimuth is in an open state, and then water spraying can be carried out to repel birds.

[0087] As Figures 8 to 10 shown, the water outlet gun barrel 5 includes a conduit 51, a spray pipe 52 and a flow dividing plate 53. Among them, one end of the conduit 51 is connected and communicated with the rear seat pipe 4, and the other end is connected and communicated with the spray pipe 52; the flow dividing plate 53 is arranged between the conduit 51 and the spray pipe 52, and the flow dividing plate 53 is used for dispersing water flow; the arc angle is located in the middle section of the conduit 51.

[0088] In the above structure, the water flow flowing through the water outlet gun barrel 5 will be divided by the flow dividing plate 53, so as to further increase the water outlet pressure, be able to drive bird flocks in a larger range, and at the same time, after the water flow is refined, even if it hits a bird, it will not cause harm, which is beneficial to protecting birds.

[0089] Specifically, the water supply mechanism 1, the main pipe 2, the electromagnetic valve 3, the rear seat pipe 4 and the water outlet gun barrel 5 are detachably connected by flanges.

[0090] As Figures 8 to 10As shown, the connecting pipe 6 includes a first section 61 and a second section 62. One end of the first section 61 is threadedly connected to the conduit 51; the shunt plate 53 abuts against the end face of the first section 61 away from the conduit 51, and the shunt plate 53 has a number of through holes; one end of the second section 62 is threadedly connected to the end of the first section 61 away from the conduit 51, and the inner wall of the second section 62 abuts against the side of the shunt plate 53 away from the first section 61; the other end of the second section 62 is connected to the nozzle 52; the connecting pipe 6 is in communication with the conduit 51 and the nozzle 52.

[0091] In the above structure, when setting the shunt plate 53, the first section 61 is connected to the conduit 51 and serves as a base, while the second section 62 is connected to the first section 61 to clamp and fix the shunt plate 53, thus facilitating the disassembly, installation and maintenance of the shunt plate 53. At the same time, due to the setting of the connecting pipe 6, the disassembly, installation and maintenance of the water outlet gun pipe 5 are also facilitated.

[0092] Furthermore, as Figure 9 shown, the inner diameter of the end of the first section 61 connecting the second section 62 is a tapered hole 601, which can make the water flow better contact the shunt plate 53 and avoid affecting the water output due to the connection between the first section 61 and the second section 62; at the same time, this structure will not affect the connection strength between the first section 61 and the second section 62.

[0093] As Figure 4 shown, the water supply mechanism 1 includes a water storage tank 11, a water outlet pipe 12, a submerged pump 13, a water inlet pipe 14 and a breather pipe 15. One end of the water outlet pipe 12 is connected and communicated with the water storage tank 11, and the other end is connected and communicated with the main pipe 2; the submerged pump 13 is arranged in the water storage tank 11, and the water outlet of the submerged pump 13 is connected and communicated with the water outlet pipe 12; one end of the water inlet pipe 14 is connected and communicated with the water storage tank 11, and the other end is used to connect the water supply mechanism 1; one end of the breather pipe 15 is connected and communicated with the water storage tank 11, and the other end is in an open state;

[0094] In the above structure, the water inlet pipe 14 is used to connect the seawater pump on the offshore platform to send seawater into the water storage tank 11;

[0095] Among them, the submerged pump 13 in the water storage tank 11 is used to transport the water flow to the water outlet pipe 12, and then the water outlet pipe 12 supplies the main pipe 2; since the water outlet pipe 12 penetrates the water storage tank 11 and is connected to the submerged pump 13, the structural integrity is good and the overall stability is high, which can avoid vibration when the submerged pump 13 works.

[0096] Among them, the breather pipe 15 is used to communicate with the atmosphere to avoid generating negative pressure inside the tank body, so as to ensure the stability of the water inlet and outlet of the water storage tank 11.

[0097] As Figure 4 and Figure 13As shown, a plurality of rib plates 7 are provided on the outer wall of the water outlet pipe. The plurality of rib plates 7 are distributed inside and outside the water storage tank 11 and are connected to the tank wall of the water storage tank 11;

[0098] With the above structure, by providing the rib plates 7, the connection stability between the water outlet pipe 12 and the water storage tank 11 can be further improved, and the vibration during the operation of the submerged pump 13 can be further reduced;

[0099] As Figure 13 shown, the side plate 8 is an arc-shaped plate. One side edge of the side plate 8 is connected to the inner wall of the water storage tank 11, and one side surface of the side plate 8 is connected to the rib plate 7 located inside the water storage tank 11;

[0100] With the above structure setting, by strengthening the connection between the rib plate 7 and the water storage tank 11 through the side plate 8, the deformation of the rib plate 7 during long-term use can be avoided, which further strengthens the connection stability between the water outlet pipe 12 and the submerged pump 13.

[0101] As Figure 14 shown, the water supply mechanism 1 further includes an inner support 16 and an outer support 17. Among them, four inner supports 16 are provided inside the water storage tank 11. The water storage tank 11 is a horizontal circular tank. The four inner supports 16 are arranged in a circular array, and the axis of the array reference circle is located on the diameter line of the water storage tank 11; the water inlet end of the submerged pump 13 is connected to the four inner supports 16;

[0102] With the above structure, since the inner support 16 cooperates with the water outlet pipe 12 to realize the fixed connection at both ends of the submerged pump 13, the submerged pump 13 and the water storage tank 11 form an integrated structural design. The submerged pump 13 does not have a displacement in the axial direction of the water outlet pipe 12, that is, it suppresses the vibration during the operation of the submerged pump 13, reduces the noise, and at the same time improves the structural strength of the water storage tank 11.

[0103] Specifically, since four inner supports 16 are provided, it can realize the stable support of the submerged pump 13 without interfering with the pumping work of the submerged pump 13. Of course, the number of the inner supports 16 may not be set to four, but too few inner supports 16 will affect the working stability of the submerged pump 13, and too many inner supports 16 will affect the pumping of the submerged pump 13. Therefore, the number of the inner supports 16 is preferably four.

[0104] As Figure 14 shown, at least two outer supports 17 are provided on the outer wall of the water storage tank 11, and at least one outer support 17 corresponds to the water inlet of the submerged pump 13;

[0105] As for the above structure, the outer support 17 is used for connecting and fixing the water supply mechanism 1 to the offshore platform. To further suppress the working vibration and ensure stability, preferably, the water inlet of the submerged pump 13 corresponds to an outer support 17, which is conducive to suppressing the working vibration through the buffer and shock absorption mechanism of the water supply mechanism 1.

[0106] Specifically, the buffer and shock absorption mechanism of the water supply mechanism 1 can be constituted by installing rubber foot pads between the outer support 17 and the ocean platform.

[0107] When there are many birds, the bird repelling water cannon needs to work continuously. Once the water stored in the water storage tank 11 is not enough, the seawater pump needs to send water into it through the water inlet pipe 14. However, the water body fluctuation generated by the water supply impact will affect the pumping efficiency of the submerged pump 13. Therefore, it is necessary to suppress the water body fluctuation during water supply.

[0108] As Figure 6 、 Figures 12 to 14 shown, the water supply mechanism 1 further includes a spoiler 18. The spoiler 18 is arranged in the water storage tank 11. The spoiler 18 divides the internal space of the water storage tank 11 into a first chamber 101 and a second chamber 102, and a number of through holes are formed on the spoiler 18 to communicate the first chamber 101 and the second chamber 102; the water inlet pipe 14 is connected and communicated with the first chamber 101; the submerged pump 13 is arranged in the second chamber 102;

[0109] As for the above structure, by arranging the spoiler 18 in the structure of the water storage tank 11 of the bird repelling cannon, it is used to separate the internal space of the water storage tank 11 to separate the water inlet pipe 14 from the submerged pump 13; this enables the water supply mechanism 1 to supply water to the water storage tank 11 through the water inlet pipe 14 during the working process of the submerged pump 13. At this time, the water flow can only overflow from the first chamber 101 into the second chamber 102 through the through holes of the spoiler 18. Therefore, the water body fluctuation mainly occurs in the first chamber 101, which can avoid the situation that the submerged pump 13 cannot draw enough water flow due to the water body fluctuation caused by water supply during the working process, thus ensuring that the water cannon tube 5 has enough water flow.

[0110] As Figure 6 、 Figure 11 and Figure 13 shown, the buffer frame 9 includes a longitudinal plate 91, a transverse plate 92 and a connecting plate 93. The water outlet of the water inlet pipe 14 is located at the top of the water storage tank 11. The two ends of the water storage tank 11 are hemispherical structures. Among them, one end of the longitudinal plate 91 is connected to the inner wall of the water storage tank 11, and the longitudinal plate 91 is located on the side of the water outlet of the water inlet pipe 14 close to the spoiler 18; one end of the transverse plate 92 is connected to the other end of the longitudinal plate 91, the other end of the transverse plate 92 faces the end of the water storage tank 11, the transverse plate 92 is perpendicular to the longitudinal plate 91, and the plate surface of the transverse plate 92 faces the water outlet of the water inlet pipe 14;

[0111] In the above structure, when the water inlet pipe 14 delivers water into the water storage tank 11, the water flow will first impact on the horizontal plate 92 for buffering. Then, under the guidance of the horizontal plate 92, it will impact on the hemispherical wall surface at the end of the water storage tank 11. After that, the water flow can flow down along the hemispherical wall surface of the water storage tank 11, thereby minimizing the impact of the water flow and suppressing the water body fluctuation to ensure the stable pumping of the submerged pump 13.

[0112] In some embodiments, the water inlet pipe 14 can extend into the interior of the water storage tank 11, and the water outlet of the water inlet pipe 14 is close to the bottom surface of the water storage tank 11. Although this can suppress the water body fluctuation to a certain extent, seawater pumps usually have a large power and a large water delivery force, which is likely to generate turbulent flow at the bottom of the water storage tank 11. The generated turbulent flow will cause the blades of the submerged pump 13 to vibrate and induce cavitation, which will greatly affect the service life of the submerged pump 13. At the same time, this will also have a great impact on the flow rate and head of the submerged pump 13. Therefore, when arranging the water inlet structure, preferably, the technical means of buffering the water flow in the above solution is adopted.

[0113] Furthermore, at least three connecting plates 93 are provided on the horizontal plate 92. The three connecting plates 93 are parallel to each other. One side of each of the three connecting plates 93 is connected to the vertical plate 91, and one side of each is connected to the inner wall of the water storage tank 11, and at least one side of the connecting plate 93 corresponds to the water outlet of the water inlet pipe 14;

[0114] In the above structure, in order to ensure the stability of the horizontal plate 92 when it is impacted by the water flow of the water inlet pipe 14, a connecting plate 93 is provided for strengthening the structure. Among the three connecting plates 93, one is directly opposite to the pipe orifice of the water inlet pipe 14 to better bear the impact force of the water flow.

[0115] In some embodiments, the connecting plate 93 corresponding to the pipe orifice of the water inlet pipe 14 adopts a triangular structure (shown as a rectangular plate structure in the figure). One corner side spans across the pipe orifice of the water inlet pipe 14, and the surface corresponding to this corner side is connected and fixed to the horizontal plate 92 to fully disperse the impact force of the water flow.

[0116] Specifically, a watertight maintenance cover for the water storage tank is provided on the water storage tank 11 to facilitate entering the interior through the maintenance cover to install and maintain the submerged pump 13.

[0117] In some embodiments, a stop valve and a drain valve are provided on the water inlet pipe 14 of the water storage tank 11 for use during debugging and maintenance.

[0118] In some embodiments, a liquid level sensor is provided in the water storage tank 11, which is used to detect the water level in the water storage tank 11. The water level has a high threshold and a low threshold. When the water level reaches the low threshold, the seawater pump melts water into the water storage tank 11. When the water level reaches the high threshold, the seawater pump stops delivering water.

[0119] In some embodiments, Figure 2 As shown, the water tank 11 is provided with an antenna 100 and a control box 200, which are used to install the circuit control board and various electronic components and transmit various signals to achieve communication, and their function is to keep the communication between the liquid level sensor, the solenoid valve, the immersion pump 13, the seawater pump of the offshore platform, the seawater pump remote control switch, the receiver, the control center, or other communication interfaces unimpeded, so as to realize centralized control, remote control and automatic control of the bird-repelling water cannon system.

[0120] The application method of the bird-repelling water cannon for an offshore platform comprises the following steps:

[0121] S1. The bird-repelling water cannon of the offshore platform is fixedly connected to the offshore platform through the external support 17, and the water inlet pipe 14 is connected to the seawater pump;

[0122] S2, adjust the solenoid valve 3 to the closed state, and ensure that the solenoid valve 3 is in the normally closed state;

[0123] S3, detect birds through bird detection radar, and when birds are found in the bird-repelling operation area, solenoid valve 3 is opened;

[0124] S4, the immersion pump 13 works to send high-pressure water into the main pipe 2, and the high-pressure water is ejected through the rear seat pipe 4 and the water outlet cannon pipe 5 in sequence to drive away the flock of birds;

[0125] S5. The seawater pump supplies water to the water storage tank 11 through the water inlet pipe 14 to ensure the water source.

[0126] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
