DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0021] In one embodiment, see Figure 1 and Figure 3 A bow mounting support device for a surveying instrument for marine engineering surveying and mapping comprises a base 3 and a surveying instrument body 5, wherein a plurality of brackets 2 are fixed on the surface of the base 3, a support shell 1 is fixed on the top of the bracket 2, an opening 6 for the surveying instrument body 5 to enter and exit is provided on the top of the support shell 1, a support plate 4 is fixedly installed on the bottom of the surveying instrument body 5, wherein a driving mechanism is provided inside the support shell 1, and the driving mechanism is used to drive the support plate 4 to move up and down, thereby controlling the surveying instrument body 5 to enter and exit the support shell 1.
[0022] In this embodiment, when the device supports the surveying instrument body 5, the surveying instrument body 5 is fixedly installed on the surface of the support plate 4, the surveying instrument body 5 is supported by the support plate 4, and the base 3 is fixed at the bow position. The installation method can be a bolted fixed connection or welding, which is not limited here. When the wind force on the sea surface is small, the surveying instrument body 5 is located outside the support shell 1, and the surveying instrument body 5 can perform normal surveying and mapping work, and the support shell 1 does not interfere with the surveying instrument body 5. When the wind force on the sea surface is large, the driving mechanism drives the surveying instrument body 5 to move downward through the support plate 4, so that the surveying instrument body 5 passes through the opening 6 at the top of the support shell 1 and enters the inside of the support shell 1, which plays a storage role for the surveying instrument body 5. At this time, the surveying instrument body 5 is protected by the support shell 1, which can effectively avoid damage to the surveying instrument body 5 caused by the large wind force.
[0023] See also Figure 3 The driving mechanism includes a trapezoidal block 17 arranged inside the supporting shell 1, and a symmetrically distributed support rod 16 is fixed on the top of the trapezoidal block 17, and the top of the support rod 16 is fixedly connected to the bottom of the supporting plate 4, wherein a push plate 12 is provided inside the supporting shell 1 for squeezing the inclined surface of the trapezoidal block 17, and the push plate 12 is fixed with a first pneumatic rod 13 and a first elastic member 15, and the end of the first elastic member 15 away from the push plate 12 is fixedly connected to the inner wall of the supporting shell 1, and a first pneumatic cylinder 7 is fixed to the outer wall of the supporting shell 1, and the end of the first pneumatic rod 13 away from the push plate 12 penetrates the side wall of the supporting shell 1 and extends into the first pneumatic cylinder 7, and the first pneumatic cylinder 7 is slidably connected to the inner wall of the first pneumatic cylinder 7, and the first pneumatic cylinder 7 is connected to an inflation component, and the inflation component is used to inflate the first pneumatic cylinder 7, and a reset component is connected to the bottom of the trapezoidal block 17. When the degree of squeezing of the trapezoidal block 17 by the push plate 12 is reduced, the reset component is used to reset the trapezoidal block 17.
[0024] When the wind force on the sea surface is relatively small, the surveying instrument body 5 is located outside the supporting shell 1, and the surveying instrument body 5 can perform normal surveying and mapping work. When the wind force on the sea surface is relatively large, the inflation component inflates the first air pressure cylinder 7, and the air pressure inside the first air pressure cylinder 7 increases and squeezes the first air pressure rod 13, so that the first air pressure rod 13 drives the push plate 12 to squeeze the inclined surface of the trapezoidal block 17. After the inclined surface of the trapezoidal block 17 is squeezed, the support plate 4 is driven downward by the support rod 16. When the bottom of the push plate 12 contacts the top of the trapezoidal block 17, the surveying instrument body 5 just moves to the inside of the supporting shell 1. At this time, through the supporting shell 1 protects the surveying instrument body 5, which can effectively avoid the damage to the surveying instrument body 5 caused by strong wind. When the wind on the sea surface weakens, the inflation component no longer inflates the first air pressure cylinder 7. The push plate 12 is driven away from the trapezoidal block 17 by the action of the first elastic member 15, and the degree of compression of the trapezoidal block 17 by the push plate 12 is reduced. The trapezoidal block 17 drives the support plate 4 to move upward through the support rod 16 under the action of the reset component, and then moves the surveying instrument body 5 to the outside of the supporting shell 1. At this time, the surveying instrument body 5 can perform normal surveying and mapping work again, wherein the first elastic member 15 can be a spring.
[0025] See also Figure 3 The reset assembly includes a limit rod 19 fixed to the bottom of the support housing 1 and symmetrically distributed, the upper end of the limit rod 19 extends into the trapezoidal block 17 and is slidably connected to the trapezoidal block 17, and a second elastic member 18 is fixed to the top of the limit rod 19, and the upper end of the second elastic member 18 is fixedly connected to the inner wall of the trapezoidal block 17; When the push plate 12 squeezes the inclined surface of the trapezoidal block 17, under the limit of the limit rod 19, the trapezoidal block 17 will move downward and squeeze the second elastic member 18, so that the second elastic member 18 is in a compressed state. When the degree of squeezing of the trapezoidal block 17 by the push plate 12 decreases, the second elastic member 18 releases its elastic potential energy, so that the trapezoidal block 17 can drive the support plate 4 to move upward through the support rod 16, thereby enabling the surveying instrument body 5 to move to the outside of the support shell 1 again, wherein the second elastic member 18 can be a spring.
[0026] See also Figure 2 The inflatable assembly includes a fixing ring 24 arranged below the supporting shell 1, a fixing rod 23 is fixed to the top of the fixing rod 23, the upper end of the fixing rod 23 is fixedly connected to the bottom of the supporting shell 1, an annular airbag 25 is fixed to the inner wall of the fixing ring 24, the annular airbag 25 is connected to the first air pipe 9, and the other end of the first air pipe 9 is connected to the inside of the first air pressure cylinder 7, wherein an extrusion component is provided inside the annular airbag 25, and the extrusion component is used to extrude the annular airbag 25; When the wind on the sea surface is strong, the extrusion component squeezes the annular airbag 25. After the annular airbag 25 is under pressure, part of the gas inside it will enter the first air cylinder 7 through the first air pipe 9, thereby increasing the air pressure inside the first air cylinder 7 and squeezing the first air rod 13.
[0027] See also Figure 2 The extrusion component includes a traction rope 27 fixed to the bottom of the supporting shell 1, a counterweight block 28 is fixed to the bottom of the traction rope 27, and an extrusion block 26 is fixed to the inner side of the annular airbag 25 and the outside of the traction rope 27.
[0028] When there is no wind on the sea or the wind is too weak to blow the counterweight 28, the counterweight 28 pulls the traction rope 27 under the action of gravity, and the traction rope 27 is in a vertical state. At this time, the squeezing block 26 does not squeeze the annular airbag 25. When the wind on the sea is strong and blows the counterweight 28, the counterweight 28 drives the traction rope 27 to swing. While the traction rope 27 swings, it drives the squeezing block 26 to squeeze the annular airbag 25, so that the gas inside the annular airbag 25 enters the first air pipe 9 into the first air pressure cylinder 7, and enters This allows the surveying and mapping body to enter the interior of the supporting shell 1. Through the provision of the annular airbag 25 and the extrusion block 26, no matter where the wind direction on the sea surface is, the traction rope 27 swings and squeezes the inner wall of the annular airbag 25 through the extrusion block 26, so that the surveying and mapping instrument body 5 can be promptly retracted into the interior of the supporting shell 1. The mechanical structure and the physical properties of wind force are used to realize the up and down movement of the support plate 4, thereby protecting the surveying and mapping instrument body 5 under strong wind conditions, without relying on sensors and control systems, and reducing failure points.
[0029] See also Figure 3 A groove is provided on the inner wall of the opening 6, a baffle 11 is slidably connected inside the groove, a third elastic member 20 is fixed on the side wall of the baffle 11, and the other end of the third elastic member 20 is fixedly connected to the inner wall of the groove, wherein a stopper 14 is fixed at the bottom of the baffle 11; When the push plate 12 finishes squeezing the trapezoidal block 17 and the surveying instrument body 5 is retracted into the supporting shell 1, the push plate 12 will push the stopper 14 while continuing to move. The push plate 12 drives the baffle 11 to seal the opening 6 at the top of the supporting shell 1 through the baffle 14, further improving the protection performance of the surveying instrument body 5. When the push plate 12 is reset, the degree of squeezing of the baffle 14 by the push plate 12 is reduced, and the baffle 11 is automatically reset under the action of the third elastic member 20, so that the opening 6 is in an open state, thereby enabling the surveying and mapping body to be moved to the outside of the supporting shell 1 again, wherein the third elastic member 20 can be a spring.
[0030] See also Figure 4A guide column 32 is fixed on the inner wall of the support shell 1, and the first gas pressure rod 13 passes through the guide column 32 and is slidably connected to the guide column 32, wherein a fixing component is provided inside the guide column 32, and the fixing component is used to fix the first gas pressure rod 13; When the surveying instrument body 5 is completely moved to the outside of the supporting shell 1, the fixing assembly inside the guide column 32 will automatically fix the first pneumatic rod 13, thereby improving the stability of the first pneumatic rod 13 and ensuring that the squeezing force of the push plate 12 on the trapezoidal block 17 does not change, thereby ensuring the stability of the surveying instrument body 5 during the surveying process.
[0031] See also Figure 2 and Figure 4 The fixing assembly includes a guide cylinder 30 fixed to the top of the support shell 1, a pin rod 33 passes through the bottom of the guide cylinder 30, the pin rod 33 is slidably connected to the inner wall of the guide cylinder 30, and the pin rod 33 passes through the inner wall of the guide column 32, wherein a pin groove 31 adapted to the pin rod 33 is provided on the side wall of the first pneumatic rod 13, the interior of the guide cylinder 30 is connected to the second air pipe 10, the other end of the second air pipe 10 is connected to the second air cylinder 8, the bottom of the second air cylinder 8 is fixedly connected to the base 3, the top of the second air cylinder 8 is passed through the second air cylinder 8, the second air cylinder 21 is slidably connected to the inner wall of the second air cylinder 8, the top of the second air cylinder 8 is fixed with a conical block 29, and the conical block 29 is connected to the top of the second air cylinder 8 through a fourth elastic member 22; When the wind force on the sea surface decreases, the counterweight block 28 is gradually reset under the action of gravity. In the process of gradually resetting the counterweight block 28, the traction rope 27 gradually becomes a vertical state. At this time, the degree of squeezing of the annular airbag 25 by the squeezing block 26 is reduced, and the first pneumatic rod 13 is reset synchronously until the pin groove 31 on the side wall of the first pneumatic rod 13 is aligned with the pin rod 33. As the counterweight block 28 continues to reset, the counterweight block 28 squeezes the inclined surface of the conical block 29, and the conical block 29 drives the second pneumatic rod 21 to move downward and squeeze the gas inside the second pneumatic cylinder 8. The gas inside the second pneumatic cylinder 8 enters the guide cylinder 30 through the second air pipe 10. The air pressure inside the guide cylinder 30 increases and squeezes the pin rod 33, thereby squeezing the pin rod 33 into the pin groove 31. The pin rod 33 passes through the pin The groove 31 plays a fixing role on the first pneumatic rod 13, effectively improving the stability of the first pneumatic rod 13. When the wind force on the sea surface is strong, the counterweight block 28 is first separated from the conical block 29 under the action of the wind force, and the conical block 29 automatically moves upward under the action of the fourth elastic member 22. The fourth elastic member 22 can be a spring. At this time, negative pressure is formed inside the second pneumatic cylinder 8, and negative pressure is simultaneously formed inside the guide cylinder 30 and suction is generated on the pin rod 33, so that the pin rod 33 moves to the outside of the pin groove 31, and the pin rod 33 no longer fixes the first pneumatic rod 13. Subsequently, the traction rope 27 swings and the annular airbag 25 can be squeezed through the squeezing block 26, so that the first pneumatic rod 13 can drive the push plate 12 to squeeze the inclined surface of the trapezoidal block 17.
[0032] Working principle: The device is supported by a support plate 4 for the surveying instrument body 5. When the wind force on the sea surface is small, the surveying instrument body 5 is located outside the supporting shell 1, and the surveying instrument body 5 can perform normal surveying and mapping work, and the supporting shell 1 does not interfere with the surveying instrument body 5. When the wind force on the sea surface is large and blows the counterweight block 28, the counterweight block 28 drives the traction rope 27 to swing, and the traction rope 27 swings while driving the extrusion block 26 to squeeze the annular airbag 25, so that the gas inside the annular airbag 25 enters the first air pressure cylinder 7 through the first air pipe 9, and the first air pressure cylinder The internal air pressure of 7 increases and squeezes the first gas pressure rod 13, and the first gas pressure rod 13 drives the push plate 12 to squeeze the inclined surface of the trapezoidal block 17. After the inclined surface of the trapezoidal block 17 is squeezed, the support plate 4 is driven downward by the support rod 16. When the bottom of the push plate 12 contacts the top of the trapezoidal block 17, the surveying instrument body 5 just moves into the inside of the supporting shell 1. At this time, the surveying instrument body 5 is protected by the supporting shell 1, which can effectively avoid the damage to the surveying instrument body 5 caused by the strong wind. When the wind on the sea surface weakens, the swing amplitude of the traction rope 27 driven by the counterweight block 28 decreases. At the same time, the squeezing degree of the annular airbag 25 by the squeezing block 26 is reduced, and negative pressure is formed inside the first air cylinder 7. The first air pressure rod 13 drives the push plate 12 to reset, and the squeezing degree of the trapezoidal block 17 by the push plate 12 is reduced. The trapezoidal block 17 drives the support plate 4 to move upward through the support rod 16, and then moves the surveying instrument body 5 to the outside of the supporting shell 1. At this time, the surveying instrument body 5 can perform normal surveying and mapping work again, and during the gradual reset of the counterweight block 28, the counterweight block 28 will squeeze the inclined surface of the conical block 29, and the conical block 29 drives the second air pressure rod 21 downward. The gas inside the second pneumatic cylinder 8 moves and squeezes the gas inside the second pneumatic cylinder 8. The gas inside the second pneumatic cylinder 8 enters into the guide cylinder 30 through the second air pipe 10. The air pressure inside the guide cylinder 30 increases and squeezes the pin rod 33, thereby squeezing the pin rod 33 into the pin groove 31 on the side wall of the first pneumatic rod 13. The pin rod 33 fixes the first pneumatic rod 13 through the pin groove 31, effectively improving the stability of the first pneumatic rod 13, so that the squeezing force of the push plate 12 on the trapezoidal block 17 will not change, thereby ensuring the stability of the surveying and mapping instrument body 5 during the surveying and mapping process.
