Abstract
Description
Technical Field
[0001] This utility model belongs to the field of depth sounding technology, specifically relating to a depth sounding instrument for measuring the elevation of complex underwater structures. Background Technology
[0002] A depth sounder is an electronic device that uses acoustic wave detection technology to measure water depth. It is widely used in many fields such as marine navigation, hydrological surveying, and engineering surveying. It is based on the theory of the propagation characteristics of sound waves in water, namely that the speed of sound waves is constant in the same medium, but changes when they enter another medium, and physical phenomena such as reflection, refraction, and scattering occur. It can measure the elevation of complex underwater structures.
[0003] When using a depth sounder, the handheld rod needs to be connected to the detection component. In practice, the handheld rod, connected to the detection component, is manually placed in the water. Measurement data is then fed back to the display module and can be printed out via the printing module. However, a significant problem arises during the connection process: the connection cable for the detection component needs to be threaded through the handheld rod before the rod is connected to the detection component via a threaded connection. Due to the length of the handheld rod, threading the cable is easily constrained by its length, making the process extremely difficult. This difficulty in threading further reduces detection efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a depth sounder for measuring the elevation of complex underwater structures. It aims to solve the problem in existing technologies where the connecting wire of the detection component needs to be threaded through a handheld rod before being connected to the detection component via a threaded connection. Because the handheld rod has a certain length, the connecting wire is easily constrained by its length when threading through it, leading to significant difficulties in the threading process. These difficulties further reduce detection efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a depth sounder for measuring the elevation of complex underwater structures, comprising a housing and a cover rotatably connected to the back of the housing via a hinge, wherein a display module, a detection component, a handheld lever, and a printing module are placed inside the housing;
[0006] The detection component consists of a probe, a connecting wire, and a docking interface, and the handheld rod is threadedly connected to the probe.
[0007] The surface of the handheld lever has two symmetrically shaped grooves. The inside of the handheld lever is provided with an annular block. A lever is connected to the surface of the annular block. A limit pin is threaded through the surface of the annular block away from the lever. A compression bolt is threaded through the surface of the rotating handle of the limit pin.
[0008] As a preferred embodiment of the present invention for measuring the elevation of complex underwater structures, the push block extends through the slide groove to the outside of the handheld rod, the size of the push block is adapted to the size of the slide groove, and the limiting pin is smaller than the size of the slide groove.
[0009] As a preferred embodiment of the depth sounder for measuring the elevation of complex underwater structures according to this utility model, the cavity size of the annular block is adapted to the cavity size of the handheld rod, and the cavity size of the annular block is adapted to the size of the docking interface end.
[0010] As a preferred embodiment of the depth sounder for measuring the elevation of complex underwater structures according to this utility model, the annular block can be slidably connected to the handheld rod via a lever.
[0011] As a preferred embodiment of the depth sounder for measuring the elevation of complex underwater structures according to this utility model, the annular block can be detachably and fixedly connected to the handheld rod by means of extrusion bolts and limiting pins.
[0012] As a preferred embodiment of the depth sounder for measuring the elevation of complex underwater structures according to this utility model, the top surface of the probe is connected to a sleeve, and the inner wall of the sleeve is adhered with a sealing gasket.
[0013] As a preferred embodiment of this invention for measuring the elevation of complex underwater structures, the sealing gasket is adapted to the size of the handheld rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By utilizing the interlocking mechanism of the annular block, the lever, the limiting pin, and the clamping bolt, the operator first inserts the mating interface of the detection component through the annular block and secures it with the limiting pin during operation. Next, the lever is moved, causing the annular block to move from one end to the other within the handheld lever. Then, the operator manually pinches the mating interface to easily pull the connecting cable into the handheld lever. During this process, the operator rotates the clamping bolt to release the limiting pin, allowing it to slide freely along the groove. This significantly reduces the difficulty of inserting the connecting cable into the handheld lever, greatly improving the assembly efficiency of the depth sounder and consequently enhancing the overall efficiency of the inspection work.
[0016] The tight fit between the sleeve and the sealing gasket effectively seals the connection point when the handheld rod is connected to the probe. When the handheld rod is submerged in water, this sealing design prevents water from seeping into the rod through the groove, thus avoiding adverse effects on the probe. This ensures stable operation of the depth sounder in complex underwater environments, extends the equipment's lifespan, and improves the reliability of measurement data. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 The present invention provides the following technical solution: a depth sounder for measuring the elevation of complex underwater structures, including a box 1 and a box cover 2 rotatably connected to the back end of the box 1 via a hinge. The box 1 contains a display module 3, a detection component 4, a handheld rod 5 and a printing module 6.
[0025] The detection component 4 consists of a probe 41, a connecting wire 42, and a docking interface 43. The handheld rod 5 is threadedly connected to the probe 41.
[0026] Two grooves 7 are symmetrically opened on the surface of the handheld lever 5. An annular block 8 is provided inside the handheld lever 5. A lever 9 is connected to the surface of the annular block 8. A limit pin 10 is threaded through the surface of the annular block 8 away from the lever 9. A compression bolt 11 is threaded through the surface of the rotating handle of the limit pin 10.
[0027] In practical use, the ZMSS-100S ultrasonic depth sounder mainly consists of a housing 1, a housing cover 2, a display module 3, a detection component 4, a handheld lever 5, and a printing module 6.
[0028] When using this depth sounder, the handheld rod 5 and the detection component 4 must first be assembled. Specifically, the connecting wire 42 of the detection component 4 is passed through the handheld rod 5, and then the handheld rod 5 is connected to the probe 41 via a threaded connection. The docking interface 43 is then connected to the display module 3. After connection, the display module 3 is activated. At this point, the operator holds the handheld rod 5 and inserts the probe 41 into the water, submerging it 5 to 10 cm underwater. The probe 41 then begins to operate. It is based on the theory of sound wave propagation characteristics in water, namely, that the speed of sound waves is constant in the same medium, but changes when they enter another medium, and physical phenomena such as reflection, refraction, and scattering occur, thus enabling the measurement of the elevation of complex underwater structures.
[0029] The measured data is printed out through the printing module 6, which is wirelessly connected to the display module 3.
[0030] Among them, display module 3 serves as the operation display screen, and printing module 6 is a small printing device. These components are all part of the ZMSS-100S ultrasonic depth sounder, and will not be described in detail here.
[0031] Preferably, the lever 9 extends through the slide groove 7 to the outside of the handheld lever 5, and the size of the lever 9 is adapted to the slide groove 7. The limiting pin 10 is smaller than the size of the slide groove 7. The annular block 8 is adapted to the cavity size of the handheld lever 5, and the cavity size of the annular block 8 is adapted to the size of the mating interface end 43. The annular block 8 can be slidably connected to the handheld lever 5 through the lever 9. The annular block 8 can be detachably and fixedly connected to the handheld lever 5 through the clamping bolt 11 and the limiting pin 10.
[0032] In practical use, during the assembly of the depth sounder, since the lever 9 is connected to the annular block 8, when the operator moves the lever 9 to slide along the matching slide groove 7, the lever 9 will drive the annular block 8 to move together. The inner circle size of the annular block 8 is compatible with the size of the docking interface end 43 of the detection component 4, which allows the docking interface end 43 to pass smoothly through the annular block 8.
[0033] Subsequently, the operator rotates the limiting pin 10, screwing it into the interior of the annular block 8. As the limiting pin 10 is screwed in, the size of the internal cavity of the annular block 8 changes, thereby restricting the mating interface end 43 and preventing the annular block 8 from detaching from the mating interface end 43 during movement. By changing the size of the internal cavity of the annular block 8, the thickness of its connecting line 42 is smaller than the internal cavity of the annular block 8, thus preventing the limiting pin 10 from squeezing the connecting line 42.
[0034] To prevent the annular block 8 from moving arbitrarily, the depth sounder is designed with a clamping bolt 11. The operator passes the clamping bolt 11 through the rotating handle of the limiting pin 10, connecting it to the surface of the hand handle 5, thereby generating a clamping force. This clamping force restricts the movement of the limiting pin 10, and with the movement of the limiting pin 10 restricted, the annular block 8 cannot move, thus ensuring that the annular block 8 is fixed in position when not in use.
[0035] Preferably, a sleeve 12 is connected to the top surface of the probe 41, and a sealing gasket 13 is adhered to the inner wall of the sleeve 12. The sealing gasket 13 is adapted to the size of the handheld rod 5.
[0036] In practical use, during the actual operation of the depth sounder, the operator needs to manually hold the handheld rod 5 and extend the probe 41 into the water, ensuring that it is submerged 5 to 10 cm underwater. Based on this operational requirement, the length of the sleeve 12 of the depth sounder is designed to be no less than 20 cm, which provides sufficient safety distance for the handheld rod 5 to extend into the water.
[0037] In this way, even if the operator applies considerable force and the depth of the handheld rod 5 submerged in water exceeds 10 cm, the safety distance effectively prevents water from seeping into the handheld rod 5 through the groove 7. This not only prevents water from adversely affecting the probe 41 and ensures the stable operation of the depth sounder in complex underwater environments, but also extends the service life of the equipment, improves the reliability of measurement data, and thus ensures safe use.
[0038] Working principle: When using the depth sounder, the operator first opens the box cover 2 and takes out the display module 3, detection component 4, handheld rod 5 and printing module 6 from the box 1, and then assembles them.
[0039] During assembly, first, the mating interface end 43 of the probe component 4 is passed through the annular block 8 inside the handheld rod 5. Next, the clamping bolt 11 is unscrewed to release the fixation of the limiting pin 10. Then, the limiting pin 10 is rotated so that it extends into the annular block 8, thereby changing the size of the internal cavity of the annular block 8. This can restrict the mating interface end 43 without affecting the connecting line 42, preventing the mating interface end 43 from detaching from the annular block 8.
[0040] Next, the lever 9 is moved so that it slides along the corresponding groove 7. During the sliding process, the lever 9 moves the annular block 8, which in turn moves the docking interface end 43 from one end of the handheld lever 5 to the other. At this point, the operator can easily pull the connecting wire 42 into the handheld lever 5 by manually pinching the docking interface end 43. In this way, the difficulty of threading the connecting wire 42 into the handheld lever 5 is significantly reduced, greatly improving the assembly efficiency of the depth sounder and thus improving the overall efficiency of the inspection work.
[0041] After completing the above steps, the handheld rod 5 is connected to the probe 41 via a threaded connection. During the connection process, the sealing gasket 13 and the sleeve 12 effectively seal the connection point, preventing water from seeping into the handheld rod 5.
[0042] Next, the docking interface 43 is connected to the display module 3. After connection, the display module 3 is activated. At this time, the operator holds the handheld lever 5 and inserts the probe 41 into the water, submerging it 5 to 10 cm underwater. The probe 41 then begins to operate. It is based on the theory of sound wave propagation characteristics in water, namely, that the speed of sound waves is constant in the same medium, but changes when they enter another medium, and physical phenomena such as reflection, refraction, and scattering occur, thereby enabling the measurement of the elevation of complex underwater structures.
[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
