Description

Technical Field

[0001] This utility model relates to an underwater measuring device, and more particularly to a Doppler underwater measuring device and a glue-filling clamp. Background Technology

[0002] The inventors disclosed a Doppler underwater measurement device in Chinese invention patent application publication number CN116106576A, which includes a circuit board, at least one adhesive portion, at least three Doppler transducers, and a housing. The housing includes a housing body, a bottom cover, and a housing space. The bottom cover is installed on the housing body to form the housing space between the housing body and the bottom cover. The circuit board is disposed in the housing space of the housing. The housing body has at least three mounting surfaces, at least three mounting slots, and at least three connecting channels. These mounting surfaces are centrally symmetrically distributed. The mounting slots are formed by recesses in the mounting surfaces. The connecting channels connect the mounting slots and the housing space. Each Doppler transducer is respectively installed in each of the mounting slots of the housing body, and the Doppler transducer is connected to the circuit board through the connecting channels of the housing body. The adhesive portion is formed by the curing of adhesive applied between the housing body and the Doppler transducers. In existing Doppler underwater measurement devices, the cross-sectional shape of the outer shell is circular, that is, the outer shell is essentially a standard cylinder. After the Doppler underwater measurement device is installed on the bottom of the towed platform with the Doppler transducer facing downwards, as the towed platform moves at high speed, the water flow acting on the outer shell causes the Doppler underwater measurement device to slide. The greater the distance between the Doppler underwater measurement device and the towed platform, the greater the swaying amplitude of the Doppler underwater measurement device. The faster the speed of the towed platform, the greater the swaying amplitude of the Doppler underwater measurement device. Furthermore, under complex hydrological conditions, the sliding direction of the Doppler underwater measurement device is uncontrollable and unpredictable, which seriously affects the detection accuracy of the Doppler underwater measurement device.

The term "a" should not be construed as a limitation on the quantity.

[0041] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 6 A preferred embodiment of the present invention, a Doppler underwater measuring device 100, will be disclosed and described in the following description. The Doppler underwater measuring device 100 includes a housing 10, a transducer 20, and an adhesive portion 30. The housing 10 has a mounting cavity 11, a wire hole 12, and a vent 13. The opening of the mounting cavity 11 faces downwards. The wire hole 12 and the vent 13 extend upwards from the mounting cavity 11, respectively. The transducer 20 has a wire 21. The transducer 20 is mounted in the mounting cavity 11 of the housing 10. The wire 21 of the transducer 20 extends through the wire hole 12 of the housing 10 to the outside of the housing 10. Adhesive is injected into the mounting cavity 11, the wire hole 12, and the vent 13 of the housing 10 and then cures to form the adhesive portion 30. Understandably, the adhesive portion 30 fills the mounting cavity 11 of the housing 10 and wraps the transducer 20, making the transducer 20 visually invisible. The adhesive portion 30 fills the wire hole 12 of the housing 10 and wraps the portion of the wire 21 of the transducer 20 located in the wire hole 12 of the housing 10. The adhesive portion 30 fills the vent hole 13 of the housing 10.

[0042] Unlike existing technologies, in the attached Figures 1 to 6In this specific example of the Doppler underwater measuring device 100 of the present invention, the horizontal cross-sectional shape of the housing 10 is teardrop-shaped, so that the housing 10 has a first wide side 101 and a first narrow side 102 relative to the first wide side 101, the first wide side 101 of the housing 10 being located in the forward direction of the Doppler underwater measuring device 100. By designing the forward direction of the housing 10 as the first wide side 101 and the relative direction as the first narrow side 102, when the Doppler underwater measuring device 100 is mounted on the bottom of a towing platform and towed by the towing platform, frictional resistance can be effectively reduced, while forming a cavity-like structure to reduce eddy current resistance, making the Doppler underwater measuring device 100 more stable in the underwater environment, thereby improving the detection accuracy of the Doppler underwater measuring device 100.

[0043] In the appendix Figures 1 to 6 In the Doppler underwater measuring device 100 of this utility model, the wire hole 12 of the housing 10 extends vertically upward from the bottom wall of the housing 10 that defines the mounting cavity 11, and the vent hole 13 extends obliquely upward from the peripheral wall of the housing 10 that defines the mounting cavity 11. This design, while maintaining a relatively small size, facilitates gas expulsion during the potting process of the housing 10, significantly reducing the amount of air bubbles in the adhesive portion 30. This is crucial for ensuring the detection accuracy of the Doppler underwater measuring device 100. Preferably, the base material of the housing 10 is aluminum, which can be formed by milling the mounting cavity 11, the wire hole 12, and the vent hole 13.

[0044] Furthermore, the Doppler underwater measuring device 100 includes a transition portion 40, which has a receiving cavity 41 and a through hole 42. The opening of the receiving cavity 41 faces upward, and the through hole 42 extends downward from the receiving cavity 41. In a specific example of the Doppler underwater measuring device 100 of this utility model, the base material of the transition portion 40 is aluminum, and the receiving cavity 41 and the through hole 42 are formed by a milling process.

[0045] The housing 10 is mounted on the bottom of the adapter 40. The position of the through hole 42 in the adapter 40 corresponds to the position of the wire hole 12 in the housing 10, allowing the lead wire 21 of the transducer 20 to extend through the through hole 42 of the adapter 40 to the receiving cavity 41 of the adapter 40, so that the terminal of the transducer 20 located at the end of the lead wire 21 is located in the receiving cavity 41 of the adapter 40. In a specific example of the Doppler underwater measuring device 100 of this utility model, the Doppler underwater measuring device 100 includes at least one device screw 70 for securely mounting the housing 10 to the bottom of the adapter 40. The specific manner in which the device screw 70 mounts the housing 10 and the adapter 40 will be described later.

[0046] Preferably, the bottom of the adapter 40 has a teardrop-shaped cross-section in the horizontal direction. Thus, the bottom of the adapter 40 has a second wide side 401 and a second narrow side 402 opposite to the second wide side 401. The second wide side 401 of the adapter 40 and the first wide side 101 of the housing 10 are located on the same side of the Doppler underwater measuring device 100, and the second narrow side 402 of the adapter 40 and the first narrow side 102 of the housing 10 are also located on the same side of the Doppler underwater measuring device 100. In this way, when the Doppler underwater measuring device 100 is towed by the towing platform, frictional resistance can be effectively reduced, and a cavity-like structure can be formed to reduce eddy current resistance, making the Doppler underwater measuring device 100 more stable in the underwater environment, thereby improving the detection accuracy of the Doppler underwater measuring device 100. The top of the adapter 40 has a circular cross-sectional shape in the horizontal direction, so that the adapter 40 can be easily installed on other components.

[0047] More preferably, the shape and size of the top surface (assembly surface) of the housing 10 are the same as the shape and size of the bottom surface (assembly surface) of the adapter 40. This ensures that after the housing 10 is installed on the bottom of the adapter 40 with its top surface and bottom surface fitting together, the Doppler underwater measuring device 100 can guarantee a natural transition between the shape of the housing 10 and the shape of the adapter 40, avoiding a height difference between the top surface of the housing 10 and the bottom surface of the adapter 40. Consequently, when the towing platform tows the Doppler underwater measuring device 100, bubbles are less likely to form around it, thus ensuring the detection accuracy of the Doppler underwater measuring device 100. In other words, the top surface of the housing 10 and the bottom surface of the adapter 40 are the same, so that after the housing 10 is installed on the bottom of the adapter 40, the Doppler underwater measuring device 100 can ensure that the shape of the housing 10 and the shape of the adapter 40 transition naturally, avoiding a height difference between the top surface of the housing 10 and the bottom surface of the adapter 40.

[0048] It is understood that since both the housing 10 and the adapter 40 are formed from a base material through a milling process, the top surface of the housing 10 and the bottom surface of the adapter 40 have high flatness. Therefore, after the housing 10 is installed on the bottom of the adapter 40 with the top surface of the housing 10 and the bottom surface of the adapter 40 fitting together, no gap will be generated between the top surface of the housing 10 and the bottom surface of the adapter 40. In this way, when the towing platform tows the Doppler underwater measuring device 100, air bubbles are less likely to be generated around the Doppler underwater measuring device 100, so as to ensure the detection accuracy of the Doppler underwater measuring device 100.

[0049] Furthermore, the housing 10 has a insertion post 14, and the opening of the wire through hole 12 is formed on the end face of the insertion post 14, that is, the wire through hole 12 of the housing 10 passes through the insertion post 14. It is understood that the insertion post 14 of the housing 10 protrudes from the top surface of the housing 10. The adapter 40 has an insertion groove 43, and the opening of the through hole 42 is formed at the bottom of the insertion groove 43. It is understood that the insertion groove 43 of the adapter 40 is formed by milling the substrate using a milling process. The shape and size of the insertion post 14 of the housing 10 match the shape and size of the insertion slot 43 of the adapter 40. The insertion post 14 of the housing 10 is inserted into the insertion slot 43 of the adapter 40. In this way, after the housing 10 is installed on the bottom of the adapter 40 with the top surface of the housing 10 and the bottom surface of the adapter 40 in contact with each other, the insertion post 14 of the housing 10 can prevent the housing 10 from moving horizontally relative to the adapter 40, thereby ensuring the reliability of the Doppler underwater measuring device 100.

[0050] Preferably, the housing 10 has a fitting groove 141 in the insertion post 14, which is formed by milling the substrate using a milling process. The Doppler underwater measuring device 100 further includes a sealing ring 50, which can be made of rubber or silicone, so that the sealing ring 50 can be deformed by compression. After the insertion post 14 of the housing 10 is inserted into the insertion groove 43 of the adapter 40 and the housing 10 is installed at the bottom of the adapter 40, the sealing ring 50 is clamped between the insertion post 14 and the adapter 40, and the sealing ring 50 is deformed by the insertion post 14 and the adapter 40 of the housing 10, so that the sealing ring 50 ensures the watertightness of the installation position of the insertion post 14 and the adapter 40 of the housing 10.

[0051] It is understood that, since the sealing ring 50 is fitted into the fitting groove 141 of the insertion post 14 of the housing 10, the relative position of the sealing ring 50 and the insertion post 14 of the housing 10 can remain unchanged during the insertion of the insertion post 14 of the housing 10 into the insertion groove 43 of the adapter 40. Thus, after the insertion post 14 of the housing 10 is inserted into the insertion groove 43 of the adapter 40, the sealing ring 50 can ensure the watertightness of the installation position of the insertion post 14 of the housing 10 and the adapter 40.

[0052] The housing 10 has two first pin holes 15, the adapter 40 has two second pin holes 44, and the Doppler underwater measuring device 100 includes two pins 60. One end of each pin 60 is inserted into each of the first pin holes 15 of the housing 10, and the other end of each pin 60 is inserted into each of the second pin holes 44 of the housing 10. In this way, the two pins 60 cooperate with each other to prevent the housing 10 and the adapter 40 from rotating relative to each other, ensuring that the second wide side 401 of the adapter 40 and the first wide side 101 of the housing 10 are located on the same side of the Doppler underwater measuring device 100, and the second narrow side 402 of the adapter 40 and the first narrow side 102 of the housing 10 are located on the same side of the Doppler underwater measuring device 100.

[0053] In the appendix Figures 1 to 6 In this specific example of the Doppler underwater measuring device 100 of the present invention, the two first pin holes 15 of the housing 10 are symmetrical with respect to the insert post 14, and correspondingly, the two second pin holes 44 of the adapter 40 are symmetrical with respect to the insert groove 43. Preferably, the inner diameter of the first pin holes 15 of the housing 10, the inner diameter of the second pin holes 44 of the adapter 40, and the outer diameter of the pin 60 are the same, so that after the opposite ends of the pin 60 are inserted into the first pin holes 15 of the housing 10 and the second pin holes 44 of the adapter 40, the pin 60 can not only prevent the housing 10 and the adapter 40 from rotating relative to each other, but also prevent the housing 10 and the adapter 40 from moving relative to each other in the horizontal direction, thereby ensuring that the housing 10 is reliably mounted on the bottom of the adapter 40.

[0054] Furthermore, the insertion post 14 of the housing 10 has at least one threaded hole 142 adjacent to the through hole 12 of the housing 10. Correspondingly, the adapter 40 has at least one screw hole 45 adjacent to the through hole 42. After the insertion post 14 of the housing 10 is inserted into the insertion slot 43 of the adapter 40, the position of the threaded hole 142 of the insertion post 14 of the housing 10 corresponds to the position of the screw hole 45 of the adapter 40. The threaded end of the device screw 70 extends into the threaded hole 142 of the insertion post 14 of the housing 10 after passing through the screw hole 45 of the adapter 40, and the threaded end of the device screw 70 is screwed onto the insertion post 14 of the housing 10. Thus, the housing 10 is reliably installed at the bottom of the adapter 40.

[0055] In the appendix Figures 1 to 6In this specific example of the Doppler underwater measuring device 100 of the present invention, the housing 10 has a plurality of threaded holes 142 in the insert pins 14, which are distributed around the through holes 12 of the housing 10. Correspondingly, the adapter 40 has a plurality of screw holes 45, which are distributed around the through holes 42 of the adapter 40. After the insert pins 14 of the housing 10 are inserted into the insert slots 43 of the adapter 40, the housing 10... The positions of the threaded holes 142 of the insert post 14 and the positions of the screw holes 45 of the adapter 40 correspond respectively. There are multiple device screws 70. After passing through the screw holes 45 of the adapter 40, the threaded ends of each device screw 70 extend into the threaded holes 142 of the insert post 14 of the housing 10, and the threaded ends of each device screw 70 are screwed onto the insert post 14 of the housing 10. In this way, the housing 10 is reliably installed on the bottom of the adapter 40.

[0056] Appendix Figures 7 to 10 A glue-filling fixture 200 is shown for manufacturing the Doppler underwater measuring device 100. Specifically, the glue-filling fixture 200 includes a top plate 210, a bottom plate 220, and at least one support rod 230. The top plate 210 has a plate hole 2101, the shape and size of which match the shape and size of the insertion post 14 of the housing 10. The bottom plate 220 has a support post 2201 with a concave support surface 22011. The surface shape of the support surface 22011 matches the surface shape of the bottom of the housing 10, and the size of the support surface 22011 is larger than the size of the opening of the mounting cavity 11 of the housing 10, so that the support surface 22011 can cover the opening of the mounting cavity 11 of the housing 10. The top of the support rod 230 is detachably locked to the top plate 210, and the bottom of the support rod 230 is detachably locked to the bottom plate 220.

[0057] Preferably, there are four support rods 230. The top of each support rod 230 is detachably locked to each corner of the top plate 210, and the bottom of each support rod 230 is detachably locked to each corner of the bottom plate 220. In this way, the top plate 210 and the bottom plate 220 can remain parallel during the glue pouring process.

[0058] In the appendix Figures 7 to 10In this specific example of the glue-pouring fixture 200 of the present invention, the top plate 210 has a downward-facing top plate groove 2102 at each of its four corners and a top plate hole 2103 extending from the top plate groove 2102 to the upper surface of the top plate 210. The inner diameter of the top plate groove 2102 is larger than the inner diameter of the top plate hole 2103. The bottom plate 220 has an upward-facing bottom plate groove 220 at each of its four corners. 2. A bottom plate hole 2203 extending from the bottom plate groove 2202 to the lower surface of the bottom plate 220, wherein the inner diameter of the bottom plate groove 2202 is larger than the inner diameter of the bottom plate hole 2203; the support rod 230 has a first screw hole 2301 and a second screw hole 2302 at its top and bottom, respectively; the outer diameter of the top of the support rod 230 is the same as the inner diameter of the top plate groove 2102 of the top plate 210; the support rod... The outer diameter of the bottom of the support rod 230 is the same as the inner diameter of the bottom plate groove 2202 of the bottom plate 220. After the bottom of the support rod 230 extends into the bottom plate groove 2202 of the bottom plate 220, the threaded end of the clamping screw 240 of the glue-filling fixture 200 extends to the second screw hole 2302 of the support rod 230 after passing through the bottom plate hole 2203 of the bottom plate 220 and is locked to the bottom of the support rod 230. The bottom of the support rod 230 is locked to the bottom plate 220. After the top of the support rod 230 extends into the top plate groove 2102 of the top plate 210, the threaded end of the clamp screw 240 extends to the first screw hole 2301 of the support rod 230 after passing through the top plate hole 2103 of the top plate 210 and is locked to the top of the support rod 230, so as to lock the top of the support rod 230 to the top plate 210.

[0059] Preferably, the top plate 210 has a pin hole 2104 that allows the end of one of the pins 60 to be inserted, wherein the pin hole 2104 of the top plate 210 is a blind hole with its opening facing downward.

[0060] Preferably, the supporting surface 22011 of the supporting column 2201 of the base plate 220 is deformable, so that during the glue pouring process, the supporting surface 22011 of the supporting column 2201 can avoid glue leakage.

Figures 7 to 10In this specific example of the glue-filling fixture 200 of the present invention, the base plate 220 may be made of rubber material, so that the support surface 22011 of the support column 2201 is deformable. Optionally, in other examples of the glue-filling fixture 200 of the present invention, the base plate 220 may be a metal plate, and the support column 2201 may be a rubber column mounted on or formed in the middle of the base plate 220, so that the support surface 22011 of the support column 2201 is deformable.

[0061] Appendix Figures 12 to 17 The specific process of applying glue using the glue-applying fixture 200 is shown.

[0062] First, refer to the appendix Figure 12 The bottom of each of the support rods 230 is locked to the four corners of the base plate 220.

[0063] Secondly, see the attached document. Figure 13 After the transducer 20 is installed in the mounting cavity 11 of the housing 10 and the wire 21 of the transducer 20 passes through the wire hole 12 of the housing 10, the assembly formed by the housing 10 and the transducer 20 is placed on the support surface 22011 of the support column 2201 of the base plate 220. At this time, the support surface 22011 of the support column 2201 closes the opening of the mounting cavity 11 of the housing 10 and the support surface 22011 and the lower surface of the housing 10 are in surface contact.

[0064] Third, see attached document. Figure 14 The bottom of one of the pins 60 is inserted into one of the first pin holes 15 of the housing 10.

[0065] Fourth, see attached document. Figure 15 and Figure 16 The tops of each support rod 230 are locked to the corners of the top plate 210 by means of the top of the pin 60 being inserted into the pin hole 2104 of the top plate 210 and the insertion post 14 of the housing 10 being inserted into the plate hole 2101 of the top plate 210. At this time, the top plate 210 avoids the vent hole 13 of the housing 10, that is, the top plate 210 does not block the vent hole 13 of the housing 10. It can be understood that the top plate 210 is used to press the housing 10 against the bottom plate 220, so that the bottom of the housing 10 is tightly attached to the support surface 22011 of the support post 2201 of the bottom plate 220.

[0066] Fifth, continue to refer to the appendix. Figure 16Adhesive is injected into the mounting cavity 11, the wiring hole 12, and the vent hole 13 of the housing 10 through the wiring hole 12. The adhesive covers the portion of the transducer 20 and the wire 21 of the transducer 20 located in the wiring hole 12 of the housing 10. During the adhesive injection process, the gas in the mounting cavity 11 of the housing 10 is discharged through the vent hole 13 of the housing 10 to reduce the amount of air bubbles in the adhesive.

[0067] Sixth, see attached document. Figure 17 After the adhesive cures, the adhesive portion 30 is formed in the mounting cavity 11, the wire hole 12, and the vent hole 13 of the housing 10. Subsequently, the top plate 210 is removed, and the tops of the top plate 210 and the support rod 230 are separated, thereby disassembling the assembly formed by the housing 10, the transducer 20, and the adhesive portion 30.

[0068] After the glue is applied, the Doppler underwater measuring device 100 can be further assembled. The specific steps are as follows: The sealing ring 50 is fitted into the fitting groove 141 of the insertion post 14 of the housing 10, and one end of each of the pins 60 is inserted into each of the first pin holes 15 of the housing 10; after the wire 21 of the transducer 20 passes through the through hole 42 of the adapter 40, the insertion post 14 of the housing 10 is inserted into the insertion groove 43 of the adapter 40, and the other end of each of the pins 60 is inserted into the second pin hole 44 of the adapter 40. At this time, the transducer 20… The terminal 22 is located in the receiving cavity 41 of the adapter 40. The sealing ring 50 is clamped between the insertion post 14 of the housing 10 and the adapter 40. The positions of each threaded hole 142 of the insertion post 14 of the housing 10 correspond one-to-one with the positions of each screw hole 45 of the adapter 40. Then, the threaded ends of each device screw 70 are screwed into each threaded hole 142 of the insertion post 14 of the housing 10 after passing through each screw hole 45 of the adapter 40, so that the housing 10 is securely installed at the bottom of the adapter 40 by these device screws 70.
