[0012] There are multiple jet pipes, and the upper ends of the jet pipes are correspondingly provided with connectors C connected to the multiple connectors B, and the lower ends of the jet pipes are respectively connected downwardly with a lead sinker through a connecting rope.

[0013] According to an embodiment of the utility model, the connector A is threadedly connected to the exhaust port; and the upper end of the air injection pipe is threadedly connected to the connector B.

[0016] According to one embodiment of the utility model, the gas generating device includes a main controller, a shell with an open top for placing dry ice, an end cover for covering the open top of the shell, a heating rod arranged in the shell, and an electric switch valve arranged at the exhaust port for controlling the switch thereof;

The heating rod is connected to the main controller through an electrical connection line A that is sealed and passes through the through hole A; the electric switch valve is connected to the main controller through an external electrical connection line B.

[0018] According to an embodiment of the utility model, the gas generating device further comprises a pressure detector connected to the main controller via an external electrical connection line C for detecting the size of the gas pressure inside the shell;

[0019] A through hole B is opened outside the shell or outside the end cover and penetrates into the shell; the pressure detector is fixedly arranged outside the shell or outside the end cover, and its detection end extends from the through hole B into the shell in a sealed manner;

For related operations, compared with the background technology that requires longer connecting pipes to conduct gas and requires a larger power air compressor to transport and increase gas pressure, the present application has a low cost of use.

[0024] Second, when the air compressor is not used in the present application, the overall volume of the present application can be greatly reduced, so that the present application occupies a small space, is easy to carry and transport, and is easy to operate. Since the present application is provided with the lead sinker to straighten the jet pipe downward, when the present application is placed at a preset depth near the deep-water blasting point, the placement stability is good and it is not easy to be displaced due to random large-scale shaking such as undercurrent, so that the present application is stable and reliable to use, and the deep-water blasting shock wave is tightly blocked.

[0025] Third, when the bubbles generated by the present application are released outward through multiple circles of the gas release holes, more bubbles at different rising heights can be formed vertically, and gradually rise vertically as much as possible. When multiple applications are placed in a row at a preset depth near a deep-water blasting point, the bubble curtain formed by the bubbles generated by the multiple applications will have a large number of bubbles and a high bubble density. Moreover, compared with the curtain formed by a single layer of bubbles, the thickness of the bubble curtain formed by the multiple applications will be relatively large. In this way, when blasting is carried out at a deep-water related blasting point, the bubble curtain formed by multiple applications can better block the shock waves generated by the blasting at the deep-water related blasting point to a certain extent, so as to better protect the aquatic organisms, hulls and other buildings that need to be protected around the blasting point as much as possible.

[0026] Fourthly, when the present application is provided with a plurality of the jet pipes, a bubble curtain of a certain width can be formed by using only one present application. Thus, when the present application is used for deep-water blasting to block shock waves, the number of the present application used can be reduced, so that the use cost can be greatly reduced.

[0027] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The bubble curtain generating device 1000 for deep water blasting and blocking shock waves according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0067] Reference Figures 1 to 4As shown, a bubble curtain generating device 1000 for deep-water blasting to block shock waves provided in an embodiment of the utility model comprises a gas generating device 10, a connecting pipe 20, an air jet pipe 30 and a plumb sinker 40;

[0068] Among them, an exhaust port 10a is provided at the bottom of the gas generating device 10, the upper end of the connecting pipe 20 is connected to the exhaust port 10a, and the lower end is connected to the upper end of the injection pipe 30; the outer wall of the injection pipe 30 is evenly provided with multiple circles of gas release holes 301 from top to bottom, and the lower end of the injection pipe 30 is connected downwardly to the lead sinker 40 through a connecting rope 50.

[0069] Based on the above, it can be clearly seen that, when the present application is implemented, it is mainly used as a bubble curtain generating device 1000 for deep-water blasting to block shock waves.

[0070] Specifically, when applying the present application, the present application is assembled according to the above-mentioned structure, and the present application is placed at a preset depth near a deep-water blasting point. Then, the gas generating device 10 is started, and gas is generated. When the gas pressure value inside the gas is greater than the water pressure value at the preset depth near the deep-water blasting point due to the generation of gas, the generated gas will flow to the jet pipe 30 through the connecting pipe 20 and be discharged from the plurality of gas release holes 301. When it contacts the deep water, bubbles are generated and slowly and continuously rise upward. In this way, a plurality of the present applications are placed in a row at a preset depth near a deep-water blasting point, and the bubbles generated by the plurality of the present applications can form a bubble curtain. At the moment when the bubble curtain is formed, blasting can be carried out at the deep-water related blasting point. At this time, the bubble curtain formed by the plurality of the present applications can block the shock wave generated by the blasting at the deep-water related blasting point to a certain extent, so as to protect the aquatic organisms, hulls and other buildings that need to be protected around the blasting point as much as possible.

[0071] Obviously, the use of the above-mentioned application will have the following technical effects:

[0072] On the one hand, the bubble curtains formed by multiple applications can block the shock waves generated by the deep-water blasting point blasting to a certain extent, so that the aquatic organisms, hulls and other buildings that need to be protected around the blasting point can be protected as much as possible. For related operations, compared with the background technology that requires a longer connecting pipe 20 to conduct gas and a more powerful air compressor to transport and increase gas pressure, the application has a low cost.

[0073] On the other hand, when the present application does not use an air compressor, the overall volume of the present application can be greatly reduced, so that the present application occupies a small space as a whole, is easy to carry and transport, and is easy to operate.

[0074] In addition, the present application is provided with the lead sinker 40 to straighten the jet pipe 30 downward, so that when the present application is placed at a preset depth near the deep-water blasting point, the placement stability is good and it is not easy to be displaced due to random and large-scale shaking due to undercurrents, etc., making the present application stable and reliable to use, and the deep-water blasting shock wave is tightly blocked.

[0075] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0076] Furthermore, in a specific implementation, according to an embodiment of the present invention, the diameter of the gas release hole 301 is D, and D=0.5mm-1.5mm.

[0077] Therefore, it is clear that when the aperture D of the gas release hole 301 is 0.5mm-1.5mm, the aperture is very small, so that deep water is not easy to enter the jet pipe 30 through it, so that the application is more reliable in use.

[0078] Preferably, in the present technical solution, the aperture D of the gas release hole 301 is set to 1.0 mm.

[0079] And, in the specific implementation, Figure 4 As shown, according to an embodiment of the present invention, each two adjacent circles of the gas release holes 301 are staggered in the up and down directions, and the spacing between each two adjacent circles of the gas release holes 301 in the up and down directions is H, wherein H=30.0mm-70.0mm.

[0080] Therefore, when the bubbles generated by the present application are released outward through multiple circles of the gas release holes 301, more bubbles at different rising heights can be formed vertically, and they can gradually rise vertically upward as much as possible. When multiple applications are placed in a row at a preset depth near a deep-water blasting point, the bubble curtain formed by the bubbles generated by the multiple applications will have a large number of bubbles and a high bubble density. Moreover, compared with the curtain formed by a single layer of bubbles, the thickness of the bubble curtain formed by the multiple applications will also be relatively large. In this way, when blasting is carried out at a deep-water related blasting point, the bubble curtain formed by multiple applications can better block the shock wave generated by the blasting at the deep-water related blasting point to a certain extent, so as to better protect the aquatic organisms, hulls and other buildings that need to be protected around the blasting point as much as possible.

[0081] Preferably, in the present technical solution, the distance H between each two adjacent circles of the gas release holes 301 in the vertical direction is set to 50.0 mm.

[0082] Furthermore, in the specific implementation, Figure 1 and Figure 2As shown, according to an embodiment of the present invention, the connecting pipe 20 is arranged in the transverse direction, and a connector A201 connected to the exhaust port 10a is arranged on its upper surface, and a plurality of connectors B202 connected to the inside thereof are evenly arranged downward from left to right on its lower bottom surface;

[0083] There are multiple jet pipes 30 , and the upper ends thereof are respectively provided with connectors C303 connected to the multiple connectors B202 , and the lower ends thereof are respectively connected downwardly to the lead sinkers 40 through connecting ropes 50 .

[0084] Therefore, it is clear that when the present application is provided with a plurality of the jet pipes 30, a bubble curtain of a certain width can be formed by using only one present application. In this way, even when the present application is used for deep-water blasting to block shock waves, the number of the present application used can be reduced, so that the cost of use can be greatly reduced.

[0085] Furthermore, in the specific implementation, continue to compare Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the connector A201 is threadedly connected to the exhaust port 10a, and after the threaded connection, they are welded together; the upper end of the air injection pipe 30 is threadedly connected to the connector B202.

[0086] In this way, the connection between the connector A201 and the exhaust port 10a is firm and sealed and not easily disconnected, and the connection between the upper end of the gas injection pipe 30 and the connector B202 is firm and not easily disconnected.

[0087] Preferably, in the technical solution, according to an embodiment of the utility model, the spacing between the plurality of the air injection pipes 30 is K, wherein K=0.5m-1.5m.

[0088] Preferably, in the present technical solution, the spacing K between the plurality of the air injection pipes 30 is set to 1.0 m.

[0089] In addition, in the specific implementation, the control Figure 1 , Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the lower end of the jet pipe 30 is closed to form a plug 302 , a fastening hole 3021 is provided outside the plug 302 , and the upper end of the connecting rope 50 is detachably inserted into the fastening hole 3021 .

[0090] From this, it can be clearly seen that since the upper end of the connecting rope 50 is detachably inserted into the tightening hole 3021, lead sinkers 40 of different weights can be used for different water depths. The deeper the water depth, the heavier the lead sinker 40 can be used to resist the buoyancy of the gas generating device 10, etc. At this time, the connecting rope 50 can be disassembled according to actual needs to replace lead sinkers 40 of different weights, so that the present application has strong flexibility in use.

[0091] Furthermore, in the specific implementation, Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, the gas generating device 10 includes a main controller 101, a shell 103 with an open top for placing dry ice 102, an end cover 104 for covering the open top of the shell 103, a heating rod 105 arranged in the shell 103, and an electric switch valve 106 arranged at the exhaust port 10a for controlling the opening thereof;

[0092] Among them, a through hole A1041 is opened outside the shell 103 or the end cover 104 and penetrates into the shell 103, and the heating rod 105 is connected to the main controller 101 through an electrical connection line A107 sealed and passed through the through hole A1041; the electric switch valve 106 is connected to the main controller 101 through an external electrical connection line B108, and the through hole A1041 is filled with high temperature and corrosion resistant sealant.

[0093] Regarding the above-mentioned present application, it should be noted that, before use, dry ice 102 is not placed in the shell 103 in advance. Only when there is a need, the end cover 104 will be opened to place dry ice 102 in the shell 103, and then the main controller 101 controls the heating rod 105 to heat the dry ice 102. When the dry ice 102 is heated, it can melt and sublimate into gas and be released into the shell 103. When the main controller 101 controls the electric switch valve 106 to open, the generated gas can be discharged through the multiple jet holes. When it contacts deep water, bubbles can be generated and slowly and continuously rise upwards.

[0094] In this way, multiple applications are placed in a row at a preset depth near a deep-water blasting point, and the bubbles generated by multiple applications can form a bubble curtain. At the moment the bubble curtain is formed, blasting can be carried out at the deep-water related blasting point. At this time, the bubble curtain formed by multiple applications can block the shock waves generated by the blasting at the deep-water related blasting point to a certain extent, so as to protect the aquatic creatures, hulls and other buildings that need to be protected around the blasting point as much as possible.

[0095] Preferably, in this technical solution, continue to control Figure 2and Figure 3 As shown, according to one embodiment of the present utility model, the gas generating device 10 further includes a pressure detector 110 connected to the main controller 101 via an external electrical connection line C109 for detecting the internal air pressure of the housing 103;

[0096] A through hole B1031 penetrating into the shell 103 is provided outside the shell 103 or outside the end cover 104; the pressure detector 110 is fixedly arranged outside the shell 103 or outside the end cover 104, and its detection end extends into the shell 103 through the through hole B1031 in a sealed manner, and the through hole B1031 is also filled with a high temperature and corrosion resistant sealant;

[0097] When the main controller 101 controls the heating rod 105 to heat up so as to drive the dry ice 102 to melt and sublimate into gas to be released into the shell 103, and when the air pressure value in the shell 103 measured by the pressure detector 110 is greater than the pressure value at the deep water position where the shell 103 is located, the main controller 101 controls the electric switch valve 106 to open.

[0098] Therefore, it can be clearly seen that the present application sets the pressure detector 110 to detect the air pressure in the shell 103. When the detected air pressure value in the shell 103 is greater than the pressure value at the deep water position where the shell 103 is located, a signal will be transmitted to the main controller 101. At this time, the main controller 101 will control the electric switch valve 106 to open, so that the gas generated in the shell 103 can be discharged through the multiple jet holes, and when it contacts the deep water, bubbles are generated to form a bubble curtain that rises upward.

[0099] It should be added that, in a specific implementation, according to an embodiment of the utility model, the end cover 104 is threadedly connected to the upper open part of the shell 103, and a sealing gasket 111 is provided at the threaded connection, so that the connection between the end cover 104 and the upper open part of the shell 103 has good sealing performance.

[0100] It should be further added that, in the specific implementation, according to an embodiment of the utility model, the end cover 104, the shell 103 and the connecting pipe 20 are all made of stainless steel to have high hardness and good corrosion resistance; the injection pipe 30 is made of plastic material so that it can be replaced at any time after use if it is broken.

[0101] It should be further added that, in a specific implementation, according to an embodiment of the present invention, the outer surfaces of the end cover 104, the shell 103 and the connecting pipe 20 are sprayed with a layer of protective paint to better prevent corrosion.

[0102] Furthermore, when the present application is specifically applied, the electrical connection line A107, the electrical connection line B108 and the electrical connection line C109 can be set to be sufficiently long according to actual needs to ensure that the present application can be placed in deep water at least at a depth of 60m.

[0103] Other embodiments and the like are not described here by way of example.

[0104] In summary, the bubble curtain generating device 1000 for deep-water blasting shock wave blocking provided by the present application, when implemented specifically, can block the shock waves generated by the deep-water blasting point blasting to a certain extent by using a plurality of bubble curtains formed by the present application, so that the aquatic organisms, hulls and other buildings that need to be protected around the blasting point can be protected as much as possible. For related operations, compared with the background technology that requires a longer connecting pipe 20 to conduct gas and a more powerful air compressor to transport and increase the gas pressure, the present application has a low cost of use.

[0105] When the air compressor is not used in the present application, the overall volume of the present application can be greatly reduced, so that the present application occupies a small space, is easy to carry and transport, and is easy to operate. Since the present application is provided with the lead sinker 40 to pull the jet pipe 30 downward, when the present application is placed at a preset depth near the deep-water blasting point, the placement stability is good and it is not easy to be displaced due to random large-scale shaking such as undercurrent, so that the present application is stable and reliable to use.

[0106] In addition, when the bubbles generated by the present application are released outward through multiple circles of the gas release holes 301, more bubbles at different rising heights can be formed vertically, and gradually rise vertically upward as much as possible. When multiple applications are placed in a row at a preset depth near a deep-water blasting point, the bubble curtain formed by the bubbles generated by the multiple applications has a large number of bubbles and a high bubble density. Moreover, compared with the curtain formed by a single layer of bubbles, the thickness of the bubble curtain formed by the multiple applications will be relatively large. In this way, when blasting is carried out at a deep-water related blasting point, the bubble curtain formed by multiple applications can better block the shock waves generated by the blasting at the deep-water related blasting point to a certain extent, so as to better protect the aquatic organisms, hulls and other buildings that need to be protected around the blasting point as much as possible.

[0107] Furthermore, when the present application is provided with a plurality of the jet pipes 30, a bubble curtain of a certain width can be formed by using only one present application. Thus, when the present application is used for deep-water blasting to block shock waves, the number of the present application used can be reduced, so that the use cost can be greatly reduced.

[0108] Furthermore, the bubble curtain generating device 1000 for deep-water blasting shock wave blocking provided by the present application is indeed extremely practical and has excellent use effect, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
