[0016] (3) Beneficial effects

[0017] The present invention provides a pressure sensor for underwater water pressure detection. It has the following beneficial effects:

[0018] (1) The underwater water pressure detection pressure sensor is provided with a peripheral protection device. When the detector is located at the bottom of the water, the rotation of the blade will drive the rotating ring to rotate accordingly, and the circumferential rotation of the connecting rod will drive the protective cover and the conical column to rotate accordingly. The conical column can effectively physically expel the aquatic organisms around the detector, and has good protection. At the same time, the circumferential motion of the connecting rod will also provide a circumferential protection effect on the periphery of the detector.

[0019] (2) The pressure sensor for underwater water pressure detection is provided with a waterweed winding device. When the connecting rod rotates due to the rotation of the blades and the rotating ring, the connecting rod can drive the winding rod to rotate accordingly. The following circular rotation of the winding rod can actively wind the waterweed around the detector. The arc plate will be squeezed and slid outward by the triangular block, so that the push plate can push out the aggregated waterweed that has been wound on the winding rod. The aggregated waterweed will sink to the bottom of the water due to its own gravity after aggregation.

[0020] (3) The underwater water pressure detection pressure sensor, when the push plate slides outward due to the push of the arc plate, the push plate will drive the No. 1 rotating rod to slide toward the blade, so that the No. 2 rotating rod will be rubbed and squeezed with the semicircular groove through the No. 2 convex ball, so that the two semicircular grooves can vibrate at the same time, thereby promoting the falling of impurities on the semicircular grooves and increasing the contact area between the semicircular grooves and the water flow.

[0021] (4) The pressure sensor for underwater water pressure detection is provided with a water flow agitation device. When the triangular block and the arc plate are rubbed and squeezed, the elastic tympanic membrane can be deformed upward, so that the elastic tympanic membrane can agitate the water flow on the upper surface upward, and a small range of impact water flow can be formed outside the triangular block, preventing some microorganisms from passing through the circular motion range of the connecting rod and being deposited outside the detector to affect the detection effect.

[0033] Example 2

[0034] like Figure 2 、 Figure 3 and Figure 4 As shown, based on Example 1, in this embodiment, a waterweed winding device is provided on the rotating ring 31, and the waterweed winding device includes:

[0035] The winding rod 41 is fixedly mounted on the outer wall of the connecting rod 34, and a push plate 42 is slidably sleeved on the outer wall of the winding rod 41, so that the push plate 42 can slide back and forth on the outer wall of the winding rod 41, and an arc plate 44 is fixedly mounted on the outer wall of the push plate 42, and a through hole 43 is opened on the push plate 42. The through hole 43 can effectively reduce the resistance of the push plate 42 when it moves, so that water can flow through the through hole 43, and an elastic element is provided between the inner outer wall of the arc plate 44 and the outer wall of the connecting rod 34. The elastic element here uses a metal spring, a metal shrapnel or other element with elastic function, so that the sliding of the arc plate 44 has an elastic restoring force, and a triangular block 61 is fixedly mounted on the outer wall of the detector 1, and the triangular end of the triangular block 61 away from the detector 1 is set to an arc surface, which is convenient for friction and extrusion between the triangular block 61 and the arc plate 44;

The blade 32 is hollow, which is convenient for the first rotating rod 51 and the second rotating rod 53 to move inside the blade 32. An elastic element is provided between the outer wall of the first rotating rod 51 and the outer wall of the second rotating rod 53. The elastic element here uses a metal spring, a metal shrapnel or other elastic element, so that the rotation of the second rotating rod 53 has an elastic restoring force. The outer wall of the bottom of the first rotating rod 51 is fixedly mounted with a No. 1 convex ball 52, and the outer wall of the top of the No. 2 rotating rod 53 is fixedly mounted with a No. 2 convex ball 54. The No. 1 convex ball 52 and the No. 2 convex ball 54 can respectively rub and squeeze with the two semicircular grooves 33. The bottom of the No. 2 rotating rod 53 is set to a spherical shape, which is convenient for the No. 2 rotating rod 53 to enter the gap between the two semicircular grooves 33;

[0037] Example 3

[0038] like Figure 2 、 Figure 5 and Figure 6 As shown, based on Example 2, in this embodiment, a water flow agitation device is provided on the detector 1, and the water flow agitation device includes:

[0039] Triangular block 61 is arranged near the outside of the arc-shaped plate 44, a water pipe 62 is opened on the triangular block 61, and an elastic tympanic membrane 64 is embedded on the outer wall of the water pipe 62. An arc-shaped push rod 63 is passed through and slidably installed in the triangular block 61, one end of the arc-shaped push rod 63 extends out of the triangular block 61 and is arranged near the outside of the arc-shaped plate 44, and the other end of the arc-shaped push rod 63 is arranged near the elastic tympanic membrane 64, a disc 65 is fixedly installed on the outer wall of the water pipe 62, and an air leakage hole 66 is opened on the disc 65, and an elastic element is provided between the outer wall of the arc-shaped push rod 63 and the outer wall of the disc 65. The elastic element here uses a metal spring, a metal shrapnel or other element with elastic function, so that the sliding of the arc-shaped push rod 63 has an elastic restoring force.

[0040] Based on the above embodiment, the working process of the present invention is that, by providing a peripheral protection device, when the detector 1 is located at the bottom of the water, the flow of water will push the blade 32 to rotate. Since the semicircular groove 33 is provided on the blade 32, the water flow will converge in the concave surface of the semicircular groove 33, so that the thrust of the water flow is more concentrated and the thrust is greater, so that the flow of water pushes the blade 32 to rotate more easily, and then the rotation of the blade 32 will drive the rotating ring 31 to follow the rotation, and the rotation of the rotating ring 31 will drive the connecting rod 34 to follow the circumferential rotation, and the circumferential rotation of the connecting rod 34 will drive the protective cover 35 to follow the rotation, and the protective cover 35 will drive the top conical column 36 to follow the rotation, and the conical column 36 can effectively physically expel the aquatic organisms around the detector 1, and has good protection. At the same time, the circumferential motion of the connecting rod 34 will also have a circumferential protection effect on the periphery of the detector 1;

[0041] By providing a waterweed winding device, when the connecting rod 34 rotates along with the rotation of the blade 32 and the swivel 31, the connecting rod 34 can drive the winding rod 41 to rotate along with it, and the following circular rotation of the winding rod 41 can actively wind the waterweed around the detector 1. Then, when the connecting rod 34 drives the arc plate 44 to move to the position of the triangular block 61, the connecting rod 34 continues to move, and the arc plate 44 can be squeezed by the inclined surface of the triangular block 61, so that the arc plate 44 will be squeezed outward by the triangular block 61 to slide, so that the arc plate 44 can push the push plate 42 to slide outward along the winding rod 41, so that the push plate 42 can push out the aggregated waterweed that has been wound on the winding rod 41. The aggregated waterweed will sink to the bottom of the water due to its own gravity after aggregation, and will not affect the detector 1. Then, when the arc plate 44 and the triangular block 61 are connected, the arc plate 44 can slide outward. After the corner block 61 is separated, the arc plate 44 returns to its initial position due to the elastic restoring force of the elastic element. When the push plate 42 slides outward due to the push of the arc plate 44, the push plate 42 drives the first rotating rod 51 to slide toward the blade 32, so that the first rotating rod 51 can drive the first convex ball 52 to rub and squeeze the semicircular groove 33. At the same time, the first rotating rod 51 also drives the second rotating rod 53 to move along. Since the bottom of the second rotating rod 53 is spherical, the second rotating rod 53 and the semicircular groove 33 are squeezed and entered into the gap between the two semicircular grooves 33, so that the second rotating rod 53 can rub and squeeze the semicircular groove 33 through the second convex ball 54, so that the two semicircular grooves 33 can vibrate at the same time, thereby promoting the falling of impurities on the semicircular groove 33 and increasing the contact area between the semicircular groove 33 and the water flow.

[0042] By providing a water flow agitation device, when the triangular block 61 and the curved plate 44 are rubbed and squeezed, the reaction force of the curved plate 44 can push the arc push rod 63 on the triangular block 61 to slide inside the triangular block 61, so that the end of the arc push rod 63 close to the elastic tympanic membrane 64 can impact the elastic tympanic membrane 64, and the elastic tympanic membrane 64 can be deformed upward, so that the elastic tympanic membrane 64 can agitate the water flow on the upper surface upward, and a small range of impact water flow can be formed outside the triangular block 61 to prevent some microorganisms from passing through the connecting rod 34. The circular motion range is deposited on the outside of the detector 1, affecting the detection effect. At the same time, due to the deformation of the elastic eardrum 64, the internal space of the water pipe 62 becomes larger, and then the air pressure inside the water pipe 62 changes, causing the air flow to flow. The flowing air flow will flow through the leakage hole 66. The air flow through the leakage hole 66 can produce a damping effect, thereby slowing down the self-recovery effect of the elastic eardrum 64, slowing down the self-deformation recovery speed of the elastic eardrum 64, and preventing the elastic eardrum 64 from quickly undergoing elastic deformation and affecting its own service life.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
