Description

Technical Field

[0001] This invention relates to the field of sensor suspension technology, and more particularly to an underwater sensor suspension system. Background Technology

[0002] Underwater sensors can detect fluctuations in underwater pressure and convert the fluctuations in the underwater pressure field into electrical signals. By recording and processing these electrical signals, underwater flow field information and acoustic data from the deep ocean can be obtained. These sensors can be widely used in fields such as marine environmental monitoring, marine resource development, and underwater navigation and communication.

[0003] To improve the accuracy of underwater data acquisition by sensors and reduce interference from the marine environment, vibration damping strips are often added to the suspension system of underwater sensors. During sea trials, when marine equipment is frequently raised and lowered into the water, the sensors are subjected to the impact of waves. The vibration damping strips are prone to breakage during their reciprocating expansion and contraction, requiring frequent replacement. This increases the workload of disassembling and assembling marine equipment and affects its service life. Summary of the Invention

An upper fixing rod and a lower fixing rod are fixedly mounted on the same side of the support rod. The height of the upper fixing rod is lower than that of the upper base, and the height of the lower fixing rod is higher than that of the lower base. The upper fixing rod is connected to the underwater sensor through two sets of symmetrically arranged suspension members, and the lower fixing rod is also connected to the underwater sensor through two sets of symmetrically arranged suspension members. The suspension members include a damping strip and a safety rope. One end of the upper damping strip and safety rope is fixed to a suspension through hole above the underwater sensor, and the other end is fixed to the upper fixing rod. One end of the lower damping strip and safety rope is fixed to a suspension through hole below the underwater sensor, and the other end is fixed to the lower fixing rod.

[0006] In the aforementioned underwater sensor suspension system, the support rod may optionally include an inner rod and an outer rod, with the inner rod slidably connected to the outer rod, the inner rod located below the outer rod, and the inner rod and outer rod fixed by an adjustment knob.

[0007] In the aforementioned underwater sensor suspension system, optionally, the upper fixed rod and the support rod are fixedly connected by three upper connecting rods, one end of which is welded to the upper fixed rod and the other end of which is welded to the support rod; the lower fixed rod and the support rod are fixedly connected by three lower connecting rods, one end of which is welded to the lower fixed rod and the other end of which is welded to the support rod.

[0008] In the aforementioned underwater sensor suspension system, optionally, a longitudinal scale is installed on the support rod.

[0009] In the aforementioned underwater sensor suspension system, it is optional to install a horizontal scale on both the upper and lower fixed rods.

[0010] In the aforementioned underwater sensor suspension system, optionally, the upper damping strip is fixed to the upper fixing rod by cotton thread, and the lower damping strip is fixed to the lower fixing rod by cotton thread.

[0011] In the aforementioned underwater sensor suspension system, optionally, two sets of retaining rings are symmetrically installed on both the upper and lower fixed rods, with two retaining rings in each set. The retaining rings are located on both sides of the fixing point of the suspension component on the upper or lower fixed rod.

[0012] In the aforementioned underwater sensor suspension system, heat shrink tubing may be installed in the suspension through-hole of the underwater sensor.

[0013] In the aforementioned underwater sensor suspension system, the effective length of the safety rope can be determined as follows:

[0014] Step 1: Fix the support rod by tightening the adjustment knob to determine the height of the support rod;

[0015] Step 2: Fix the upper end of the underwater sensor to the upper fixing rod using the two upper damping strips, and fix the lower end of the underwater sensor to the lower fixing rod using the two lower damping strips.

[0016] Step 3: Place the suspension system in the air, measure the distance w'1 between the two fixed points of the two upper damping strips on the upper fixed rod, measure the distance w'2 between the two lower damping strips on the lower fixed rod, measure the distance h'1 between the upper end of the underwater sensor and the upper fixed rod, and measure the distance h'2 between the lower end of the underwater sensor and the lower fixed rod.

[0017] Step 4: Place the suspension system in the seawater tank, measure the distance w”1 between the two fixed points of the two upper damping strips on the upper fixed rod, measure the distance w”2 between the two lower damping strips on the lower fixed rod, measure the distance h”1 between the upper end of the underwater sensor and the upper fixed rod, and measure the distance h”2 between the lower end of the underwater sensor and the lower fixed rod.

[0027] The underwater sensor suspension system provided by this invention includes a support rod, with an upper fixed rod and a lower fixed rod fixedly installed on the same side of the support rod. The upper fixed rod is connected to the underwater sensor through two sets of symmetrically arranged suspension components, and the lower fixed rod is also connected to the underwater sensor through two sets of symmetrically arranged suspension components. The suspension components include vibration damping strips and safety ropes. The underwater sensor is fixed by four vibration damping strips, which serve to dampen vibrations. The safety ropes protect the vibration damping strips. When the underwater sensor is subjected to the impact force of waves, the safety ropes protect the vibration damping strips, making them less prone to breakage and eliminating the need for frequent replacement of the vibration damping strips. This reduces the workload of disassembling and assembling marine equipment and extends the service life of the equipment.

In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] like Figure 1As shown, the present invention provides an underwater sensor suspension system, including a support rod 5. Bases 1 are fixedly installed at both ends of the support rod 5. An upper fixing rod 2 and a lower fixing rod 6 are fixedly installed on the same side of the support rod 5. The height of the upper fixing rod 2 is lower than that of the upper base 1, and the height of the lower fixing rod 6 is higher than that of the lower base 1. The upper fixing rod 2 is connected to the underwater sensor 9 by two sets of symmetrically arranged suspension components, and the lower fixing rod 6 is also connected to the underwater sensor 9 by two sets of symmetrically arranged suspension components. The suspension components include a damping strip 10 and a safety rope 11. One end of the upper damping strip 10 and safety rope 11 is fixed to a suspension through-hole above the underwater sensor 9, and the other end is fixed to the upper fixing rod 2. One end of the lower damping strip 10 and safety rope 11 is fixed to a suspension through-hole below the underwater sensor 9, and the other end is fixed to the lower fixing rod 6.

[0038] It should be noted that the fixing points of the two upper damping strips 10 are symmetrically distributed about the support rod 5, and the fixing points of the two lower damping strips 10 are also symmetrically distributed about the support rod 5. The upper fixing rod 2 and the lower fixing rod 6 are used to fix the damping strips 10 and the safety rope 11. Both the upper fixing rod 2 and the lower fixing rod 6 are made of cylindrical stainless steel with no sharp edges to avoid scratching the damping strips 10 and the safety rope 11. The damping strips 10 are made of stretchable rubber material, and there are four of them, each a single strand. The safety rope 11 is made of Kevlar fiber material, and there are four of them, each a double strand, and it is not stretchable. The underwater sensor 9 is fixed by the four damping strips 10. The damping strips 10 play a role in damping vibration, and the safety rope 11 is used to protect the damping strips 10. When the underwater sensor 9 is subjected to the impact force of waves, the safety rope 11 protects the damping strips 10, making the damping strips 10 less prone to breakage. This reduces the need for frequent replacement of the damping strips, reduces the workload of disassembling and assembling marine equipment, and improves the service life of the equipment.

[0039] Furthermore, the support rod 5 includes an inner rod and an outer rod, the inner rod and the outer rod are slidably connected, the inner rod is located below the outer rod, and the inner rod and the outer rod are fixed by adjusting the knob 4.

[0040] It should be noted that the adjustment knob 4 is threadedly connected to the outer rod, and the support rod 5 is a telescopic structure. After the inner rod slides to a suitable position inside the outer rod, the adjustment knob 4 is tightened to press the inner rod, thereby fixing the length of the support rod 5. The overall height of the suspension system is adjusted by extending and retracting the support rod 5.

[0041] Furthermore, the upper fixed rod 2 and the support rod 5 are fixedly connected by three upper connecting rods. One end of the upper connecting rod is welded to the upper fixed rod 2, and the other end of the upper connecting rod is welded to the support rod 5. The lower fixed rod 6 and the support rod 5 are fixedly connected by three lower connecting rods. One end of the lower connecting rod is welded to the lower fixed rod 6, and the other end of the lower connecting rod is welded to the support rod 5.

[0042] It should be noted that the upper fixing rod 2 and the support rod 5 are welded together and reinforced with a triangular shape, and the lower fixing rod 6 and the support rod 5 are welded together and reinforced with a triangular shape.

[0043] Furthermore, a longitudinal scale 3 is installed on the support rod 5.

[0044] It should be noted that the longitudinal scale 3 is used to determine the distance between the upper end of the underwater sensor 9 and the upper fixed rod 2, as well as the distance between the lower end of the underwater sensor 9 and the lower fixed rod 6.

[0045] Furthermore, a horizontal scale 8 is provided on both the upper fixing rod 2 and the lower fixing rod 6.

[0046] It should be noted that the horizontal scale 8 on the upper fixing rod 2 is used to determine the distance between the fixing points of the two upper damping strips 10 (or safety ropes 11); the horizontal scale 8 on the lower fixing rod 6 is used to determine the distance between the fixing points of the two lower damping strips 10 (or safety ropes 11).

[0047] Furthermore, the upper damping strip 10 is fixed to the upper fixing rod 2 with cotton thread, and the lower damping strip 10 is fixed to the lower fixing rod 6 with cotton thread.

[0048] It should be noted that the cotton thread is used to fix the damping strip 10 to the upper fixing rod 2 or the lower fixing rod 6. Using cotton thread can effectively avoid scratching the damping strip 10, so as not to affect the damping performance of the damping strip 10.

[0049] Furthermore, two sets of retaining rings 7 are symmetrically installed on both the upper fixing rod 2 and the lower fixing rod 6. Each set of retaining rings 7 consists of two rings, which are located on both sides of the fixing point of the suspension component on the upper fixing rod 2 or the lower fixing rod 6.

[0050] It should be noted that each suspension component includes a damping strip 10 and a safety rope 11. A safety rope 11 is provided next to each damping strip 10. The fixing points of adjacent damping strips 10 and safety ropes 11 coincide. The damping strips 10 and safety ropes 11 located above are respectively equipped with retaining rings 7 on both sides of the fixing point on the upper fixing rod 2. The damping strips 10 and safety ropes 11 located below are respectively equipped with retaining rings 7 on both sides of the fixing point on the lower fixing rod 6. The retaining rings 7 are used to prevent the damping strips 10 and safety ropes 11 from slipping.

[0051] Furthermore, a heat shrink tubing is installed in the suspension through-hole of the underwater sensor 9.

[0052] It should be noted that the heat shrink tubing is placed in the suspension through-hole of the underwater sensor 9 to increase friction and prevent the underwater sensor 9 from slipping between the safety rope 11.

[0053] like Figure 1 , Figure 2 As shown, the effective length of the safety rope 11 is determined as follows:

[0054] Step 1: Fix the support rod 5 by tightening the adjustment knob 4 to determine the height of the support rod 5;

[0055] Step 2: Fix the upper end of the underwater sensor 9 to the upper fixing rod 2 using the two upper damping strips 10, and fix the lower end of the underwater sensor 9 to the lower fixing rod 6 using the two lower damping strips 10.

[0056] Step 3: Place the suspension system in the air, measure the distance w'1 between the two fixed points of the two upper damping strips 10 on the upper fixed rod 2, measure the distance w'2 between the two lower damping strips 10 on the lower fixed rod 6, measure the distance h'1 between the upper end of the underwater sensor 9 and the upper fixed rod 2, and measure the distance h'2 between the lower end of the underwater sensor 9 and the lower fixed rod 6.

[0057] Step 4: Place the suspension system in the seawater tank, measure the distance w”1 between the two fixed points of the two upper damping strips 10 on the upper fixed rod 2, measure the distance w”2 between the two lower damping strips 10 on the lower fixed rod 6, measure the distance h”1 between the upper end of the underwater sensor 9 and the upper fixed rod 2, and measure the distance h”2 between the lower end of the underwater sensor 9 and the lower fixed rod 6.

[0058] Step 5: Using the effective length calculation equation of the safety rope 11, obtain the range of values ​​for the effective length l1 of the upper safety rope 11 and the range of values ​​for the effective length l2 of the lower safety rope 11.

[0059] It should be noted that the safety rope 11 was not installed on the suspension system during the determination of its effective length; the influence of the weight and buoyancy of the damping strip 10 and the safety rope 11 on the suspension system was ignored when measuring various distance parameters; the suspension system was placed in a seawater tank with the free surface of the tank completely submerging the suspension system; when determining the effective length of the upper and lower safety ropes 11, it was necessary to consider that the safety rope 11 could withstand the tension of the underwater sensor 9 when the marine equipment entered and exited the water, limiting the maximum extension and contraction of the damping strip 10, reducing the frequency of extension and contraction of the damping strip 10, and protecting the damping strip 10; at the same time, when the underwater sensor 9 was working underwater, the safety rope 11 did not bear any force, allowing the damping performance of the damping strip 10 to be utilized, avoiding frequent disassembly and assembly of the marine equipment, and extending the service life of the marine equipment.

[0060] like Figure 2As shown, the underwater sensor 9 has dimensions a*b (mm). Vibration damping strips 10 are used to suspend the underwater sensor 9 on the upper fixing rod 2 and the lower fixing rod 6, and clamping rings 7 are fixedly installed. The fixing points of the two upper vibration damping strips 10 are symmetrically distributed about the support rod 5, and the fixing points of the two lower vibration damping strips 10 are also symmetrically distributed about the support rod 5, ensuring that the distance between the fixing points meets the actual suspension requirements of the underwater sensor 9. In determining the effective length of the safety rope 11, as... Figure 2 As shown, the solid black line represents the suspension system in a fixed state in the air; the dashed gray line represents the suspension system in a fixed state in seawater.

[0061] The effective length of the safety rope 11 should be kept within a reasonable range to ensure that the vibration damping strip 10 effectively performs its vibration damping performance when the marine equipment is working. To ensure the vibration damping performance of the vibration damping strip 10, when the underwater sensor 9 is working underwater, the effective length of the upper safety rope 11 should be greater than the length of the upper vibration damping strip 10 after underwater extension, so that the safety rope 11 is in a slack state. The vibration damping strip 10 bears the fluid force on the underwater sensor 9 and performs a vibration damping function with the vibration of the underwater sensor 9. The effective length of the lower safety rope 11 is greater than the maximum length of the lower vibration damping strip 10 after underwater extension, so that the lower safety rope 11 is in a slack state to protect the lower vibration damping strip.

[0062] To ensure that the safety rope 11 plays a protective role, when the marine equipment enters or leaves the water, the safety rope 11 can withstand the tension of the underwater sensor 9, restrict the free extension and contraction of the vibration damping strip 10, and the safety rope is in a taut state to withstand the tension of the underwater sensor 9 when entering or leaving the water, and restrict the vibration damping strip to not elongate with the increase of impact force within a certain length.

[0063] The effects of the weight and buoyancy of the damping strip 10 and safety rope 11 on the suspension system are ignored. When the suspension system is placed in the air (e.g.) Figure 3 As shown, under the weight of the underwater sensor 9 itself, the two upper damping strips 10 are in a state of free tension. The elongation Δx1 of the two upper damping strips 10 is set to be the same, and the length of the upper damping strip 10 is l'1. The elongation Δx2 of the two lower damping strips 10 is set to be the same, and Δx2 is less than Δx1. The length of the lower damping strip 10 is l'2. The distance between the upper end of the underwater sensor 9 and the upper fixed rod 2 is h'1, and the distance between the lower end of the underwater sensor 9 and the lower fixed rod 6 is h'2. The distance between the two fixed points of the two upper damping strips 10 on the upper fixed rod 2 is w'1, and the distance between the two lower damping strips 10 on the lower fixed rod 6 is w'2.

[0064] When the suspension system is placed in seawater (e.g.) Figure 4As shown, under the action of buoyancy, the elongation Δx1 of the two upper damping strips 10 decreases. Assuming the elongation of the two upper damping strips 10 changes the same, the length of the upper damping strip 10 is l”1. Under the action of buoyancy, the underwater sensor 9 produces a vertically upward displacement, and the elongation Δx2 of the two lower damping strips 10 of the underwater sensor 9 increases. Assuming the elongation of the two lower damping strips 10 changes the same, the length of the lower damping strip 10 is l”2. The underwater sensor 9… The distance between the upper end of the underwater sensor 9 and the upper fixed rod 2 is h”1, and the distance between the lower end of the underwater sensor 9 and the lower fixed rod 6 is h”2; the distance between the two fixed points of the two upper damping strips 10 on the upper fixed rod 2 is w”1, and the distance between the two fixed points of the two lower damping strips 10 on the lower fixed rod 6 is w”2. Due to the limiting effect of the retaining ring 7, the distance between the fixed points of the upper and lower damping strips 10 is set to remain unchanged, that is, w’1=w”1, w’2=w”2.

[0067]

[0068]

[0069]

[0070] The effective length of the upper safety rope 11 is:

[0071] l”1<l1<l'1

[0072] Right now,

[0073] When the effective length of the upper safety rope 11 satisfies the relationship l”1<l<l'1, the effective length of the upper safety rope 11 is less than the length l'1 of the upper damping strip 10 in the air. When entering or leaving the water, the safety rope 11 is in a taut state and is under tension. The tension on the damping strip 10 decreases, and the elongation of the damping strip 10 does not change with the increase of the impact force. When the effective length of the upper safety rope 11 is greater than the length l”1 of the upper underwater damping strip 10, the safety rope is in a slack state underwater. The damping strip bears the fluid force on the sensor and plays a damping role.

[0074] The effective length of the lower safety rope 11 is:

[0075] l”2<l2

[0076] Right now,

[0077] When the effective length of the lower safety rope 11 satisfies the relationship l”2<l2, the effective length of the lower safety rope is greater than the length l”2 of the underwater lower damping strip. The safety rope is in a slack state, the damping strip bears the fluid force on the underwater sensor 9, the damping strip plays a damping role, and the lower safety rope can limit the vertical tension and extension of the lower damping strip, protecting the lower damping strip.

[0078] For example, the dimensions of the underwater sensor 9 are: a = 100mm, b = 100mm. The dimensions of the damping strips in the air suspension system are: the distance between the two fixed points of the two upper damping strips 10 on the upper fixed rod 2 is w'1 = 210mm, and the distance between the two fixed points of the two lower damping strips 10 on the lower fixed rod 6 is w'2 = 248mm; the distance between the upper end of the underwater sensor 9 and the upper fixed rod 2 is h'1 = 100mm, and the distance between the lower end of the underwater sensor 9 and the lower fixed rod 6 is h'2 = 128mm; the calculated length of the upper damping strip 10 is l'1 = 114mm, and the length of the lower damping strip 10 is l'2 = 147mm.

[0079] The dimensions of the vibration damping strips in the suspension system in seawater are as follows: the distance between the two fixed points of the two upper vibration damping strips 10 on the upper fixed rod 2 is w”1 = 210 mm; the distance between the two fixed points of the two lower vibration damping strips 10 on the lower fixed rod 6 is w”2 = 248 mm; the distance between the upper end of the underwater sensor 9 and the upper fixed rod 2 is h”1 = 95 mm; the distance between the lower end of the underwater sensor 9 and the lower fixed rod 6 is h”2 = 133 mm; the calculated length of the upper vibration damping strip 10 is l”1 = 108 mm, and the length of the lower vibration damping strip 10 is l”2 = 152 mm.

[0080] According to the calculation formula for the effective length of the upper safety rope 11, 108mm < l1 < 114mm. To facilitate the selection of the safety rope value, the finite length of the safety rope is set to l1 = 110mm. According to the calculation formula for the effective length of the lower safety rope 11, l2 > 152mm. To facilitate the selection of the safety rope value, the finite length of the safety rope is set to l2 = 160mm.

[0081] Based on the effective lengths of the upper and lower safety ropes 11, the safety ropes 11 were attached to the suspension system, and their effectiveness was tested in air and in a test water tank. The effective length of the upper safety rope 11 was less than the length of the damping strip in the air; therefore, the safety rope was under tension when entering and exiting the water, and was in a taut state. The effective length of the upper safety rope was greater than the length of the underwater damping strip; therefore, underwater, the safety rope was in a slack state, and the damping strip could perform its damping function. The effective length of the lower safety rope was greater than the length of the underwater damping strip; therefore, underwater, the lower safety rope was in a slack state, and the damping strip bore the fluid force on the sensor, thus performing its damping function.

[0082] The underwater sensor suspension system provided by this invention includes a support rod 5. An upper fixing rod 2 and a lower fixing rod 6 are fixedly installed on the same side of the support rod 5. The upper fixing rod 2 is connected to the underwater sensor 9 through two sets of symmetrically arranged suspension components, and the lower fixing rod 6 is also connected to the underwater sensor 9 through two sets of symmetrically arranged suspension components. The suspension components include vibration damping strips 10 and safety ropes 11. The underwater sensor 9 is fixed by four vibration damping strips 10, which play a role in vibration damping. The safety ropes 11 are used to protect the vibration damping strips 10. When the underwater sensor 9 is subjected to the impact force of waves, the safety ropes 11 protect the vibration damping strips 10, making the vibration damping strips 10 less prone to breakage. This eliminates the need for frequent replacement of the vibration damping strips, reduces the workload of disassembling and assembling marine equipment, and improves the service life of the equipment.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
