Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of underwater topographic surveying, and particularly relates to a fixing device capable of adjusting the position of a transducer. Background Art
[0002] A single-beam depth sounder is an instrument that uses the principle of echo sounding to detect water depth. It mainly consists of a depth sounder, a GNSS device, a transducer rod, and a depth transducer (hereinafter referred to as a transducer), and is widely used in underwater topographic surveying of reservoir areas, waterway mapping, marine exploration, environmental monitoring, and other fields. After connecting the GNSS device, each water depth point measured by the depth sounder corresponds to a positioning coordinate.
[0003] During installation, the transducer is usually fixedly installed at the lower end of the transducer rod, the GNSS device is fixed at the upper end of the transducer rod, and then the transducer rod is fixed to the side of the ship, and the whole transducer rod is kept vertical, so that the phase center of the GNSS device, the central axis of the transducer rod, and the center of the transducer are on a vertical line, realizing the accuracy of underwater sounding points and corresponding coordinates.
[0004] However, because the traditional transducer rod is fixed to the hull, the arrangement position and depth of the transducer are fixed. This method does not take into account the complexity of the hydrological environment. Especially in natural rivers, water conditions such as slope drop, rapids, and wind waves may cause changes in the actual draft depth. The transducer with a fixed depth may cause loss of measurement signals or reduction of measurement accuracy due to depth mismatch.
[0005] At the same time, in a complex river environment, the underwater topography is diverse, and obstacles such as rocks and fallen stones are unevenly distributed. If the transducer is fixed at a certain depth, the risk of collision with riverbed rocks will increase significantly. This will not only may cause equipment damage, but also lead to measurement interruption, further reducing work efficiency and economic benefits. Summary of the Utility Model
[0006] The technical problem to be solved by the utility model is to provide a fixing device capable of adjusting the position of a transducer. The transducer rod is slidably arranged in the installation sleeve and is matched with a lateral movement mechanism and a flipping mechanism, so that the position of the transducer can be adjusted according to the actual water conditions, ensuring accurate measurement and avoiding damage to the transducer caused by collision with foreign objects, and ensuring safety.
[0007] In view of the above technical problems, the technical solution provided by the present utility model is a fixing device for adjusting the position of a transducer, which includes a transducer rod, an installation sleeve and an installation structure. The installation sleeve is installed on the hull through the installation structure. The transducer rod is slidably inserted into the installation sleeve. GNSS receivers and transducers are respectively installed at both ends of the transducer rod. The installation structure includes a lateral movement mechanism and a flipping mechanism. The lateral movement mechanism is used to realize the lateral movement of the installation sleeve, and the flipping mechanism is used to realize the flipping of the installation sleeve to drive the transducer in and out of the water surface.
[0008] Further, a plurality of adjustment holes are arranged at intervals along the axial direction of the peripheral surface of the installation sleeve, and corresponding fixing holes are arranged on the transducer rod. The transducer rod is fixed on the installation sleeve through fixing pins passing through the adjustment holes and extending into the fixing holes.
[0009] Further, a guide rod parallel to its axis is fixedly arranged in the fixing hole. A corresponding guide hole is opened at the position of the inner end of the fixing pin corresponding to the guide rod. The guide rod is slidably matched with the guide hole. A spring is connected between the inner end of the fixing pin and the inner end of the fixing hole.
[0010] Further, a locking structure is arranged between the upper end of the installation sleeve and the transducer rod. The locking structure includes a plurality of elastic locking pieces arranged at intervals along the circumference and a locking cap threadedly matched with the elastic locking pieces.
[0011] Further, the lateral movement mechanism includes a mounting base and a mounting block. The mounting base is used for fixed installation on the hull. The mounting block connects the installation sleeve and the mounting base, and the mounting block is slidably arranged on the mounting base in the lateral direction.
[0012] Further, a sliding groove for lateral movement is opened on the side surface of the mounting base facing away from the mounting block. The size of the mounting block is adapted to the sliding groove, and the mounting block is slidably arranged in the sliding groove.
[0013] Further, a first arc surface is arranged on the inner wall of the sliding groove, and a second arc surface adapted to the first arc surface is arranged at one end of the mounting block facing the hull.
[0014] Further, the first arc surface is a semi-circular shape protruding outward.
[0015] Further, a ball is arranged between the bottom surface of the sliding groove and the mounting block.
[0016] Further, the lateral movement mechanism further includes a driving mechanism. The driving mechanism includes a driving screw rod rotatably arranged in the sliding groove. The length direction of the driving screw rod extends in the lateral direction, and the mounting block is threadedly connected with the driving screw rod.
[0017] Furthermore, the mounting sleeve is attached to a side of the mounting block facing away from the mounting seat, and the flip mechanism includes a hinge joint arranged at the outer periphery of the mounting sleeve and the upper end of the mounting block.
[0018] Furthermore, the upper end surface of the mounting seat is higher than the upper end surface of the mounting block, and the height difference between the upper end surface of the mounting seat and the upper end surface of the mounting block is adapted to the closed thickness of the hinged leaf.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] (1) During measurement, the installation sleeve is kept in a vertical state, and the transducer rod is slidably installed in the installation sleeve. The draft depth of the transducer at the lower end of the transducer rod can be adjusted to meet the measurement requirements of different water depths. At the same time, when encountering high waves or rapids, the transducer can be lowered in time to improve the precision and accuracy of the measurement. At the same time, the installation sleeve can move horizontally in the horizontal direction under the action of the lateral movement mechanism, which is convenient for adjusting the orientation of the transducer in a complex river environment. With the flipping of the flipping mechanism and the lifting of the transducer, the risk of collision between the transducer and water plants, reefs, etc. can be reduced, and it can adapt to measurements under various hydrological conditions. The installation sleeve can also drive the transducer in and out of the water by using the flipping mechanism. When not measuring, the transducer can be exposed to the water surface to improve safety. Using the GNSS receiver, on the one hand, the measurement position can be located, and on the other hand, it is convenient to obtain the height value of the transducer to ensure the measurement accuracy.
[0021] (2) By using the guide rod and the guide hole in combination, when adjusting the height position of the transducer rod, the fixing pin can be ensured to extend and retract along a fixed direction. After the fixing pin is adjusted into place, the adjustment hole can be automatically popped out by a spring, thereby improving convenience.
[0022] (3) The locking structure can be used to lock the mounting sleeve and the transducer rod together to ensure accurate measurement.
[0023] (4) The first arc surface cooperates with the second arc surface and the provided balls, so as to reduce the friction between the mounting block and the sliding groove, and the balls can prevent the mounting block from being separated from the sliding groove to a certain extent.
[0024] (5) The driving mechanism can facilitate driving the mounting block to slide in the sliding groove on the one hand, and can prevent the mounting block from falling off from the sliding groove on the other hand by limiting the driving screw.
[0025] (6) The height difference between the upper end surface of the mounting seat and the upper end surface of the mounting block is adapted to the closing thickness of the hinged joint. In this way, after the mounting sleeve is flipped to a horizontal state through the flipping mechanism, the circumferential surface of the mounting sleeve can be attached to the upper end surface of the mounting seat, and the mounting seat is used to bear the load, thereby improving stability and safety.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application: Specific embodiment 1:
[0035] In this embodiment, as Figure 1 shown, the length direction of the mounting base 91 is horizontal.
[0036] Refer to Figures 1 to 6, a fixing device for adjusting the position of a transducer (hereinafter referred to as the fixing device) of the present utility model, includes a transducer rod 1, an installation sleeve 5 and an installation structure. The installation sleeve 5 is installed on the hull 4 through the installation structure. The transducer rod 1 slidably passes through the installation sleeve 5. GNSS receivers 2 and transducers 3 are respectively installed at both ends of the transducer rod 1. When work is required, the installation sleeve 5 is arranged vertically, so that the transducer rod 1 is in a vertical state, and the transducer 3 is at the lower end of the transducer rod 1 and extends into the water. The installation structure includes a lateral movement mechanism 9 and a flipping mechanism 10. The lateral movement mechanism 9 is used to realize the lateral movement of the installation sleeve 5, and the flipping mechanism 10 is used to realize the flipping of the installation sleeve 5 to drive the transducer 3 to enter and exit the water surface around the rotation axis of the flipping mechanism 10.
[0037] Specifically, as Figure 2 , 3 shown, a plurality of adjustment holes 51 are arranged at intervals along the axial direction of the circumferential surface of the installation sleeve 5. In this embodiment, the distance between adjacent adjustment holes 51 is 10 cm. The adjustment holes 51 penetrate through the inner and outer circumferential surfaces of the installation sleeve 5. At the position corresponding to the adjustment holes 51 on the upper part of the transducer rod 1, fixing holes 110 extending inward are opened. The size of the fixing holes 110 is adapted to the size of the adjustment holes 51, and the axis of the fixing holes 110 is parallel to the axis of the adjustment holes 51. In actual use, the transducer rod 1 is fixedly installed on the installation sleeve 5 through a fixing pin 6 that passes through the adjustment holes 51 and extends into the fixing holes 110. In this way, by aligning the fixing holes 110 with the adjustment holes 51 at different height positions, the draft depth of the bottom transducer 3 can be adjusted.
[0038] In this embodiment, preferably, as Figure 3 shown, a guide rod 7 is fixedly arranged in the fixing hole 110. Specifically, the guide rod 7 is coaxially arranged with the fixing hole 110. At the position corresponding to the guide rod 7 at the inner end of the fixing pin 6, a matching guide hole 61 is correspondingly opened. The guide rod 7 is slidably matched with the guide hole 61, and a spring 8 is connected between the inner end of the fixing pin 6 and the inner end of the fixing hole 110. Both ends of the spring 8 are fixed to the opposite ends of the fixing pin 6 and the fixing hole 110 respectively. In this way, by using the cooperation of the guide rod 7 and the guide hole 61, when adjusting the height position of the transducer rod 1, it can be ensured that the fixing pin 6 expands and contracts along a fixed direction. After the fixing pin 6 is adjusted in place, the spring 8 can automatically pop out of the adjustment hole 51, improving the convenience.
[0039] Of course, in other implementations, when actual usage requirements are met, a mounting hole can be opened on the circumferential surface of the mounting sleeve 5, and an adaptive slide groove can be opened at the corresponding installation position on the transducer rod 1, and the slide groove is divided into two sections from the inside to the outside, and the width of the inner section is greater than the width of the outer section. An adaptive fixing bolt 102 is slidably set in the slide groove, and the big head end of the fixing bolt is slidably set in the inner section. The threaded end of the fixing bolt 102 passes through the mounting hole and is screwed with a fixing nut. In this way, the transducer rod 1 and the mounting sleeve 5 can be locked and fixed by tightening the mounting nut. When the position of the transducer rod 1 needs to be adjusted, loosen the mounting nut, slide the transducer rod 1, adjust it to a suitable position, and then tighten the mounting nut to fix it.
[0040] Preferably, in this embodiment, a locking structure 11 is provided between the upper end of the mounting sleeve 5 and the transducer rod 1. Specifically, Figure 3 As shown, the locking structure 11 includes a plurality of elastic locking pieces 111 arranged at intervals along the circumferential direction at the upper end of the mounting sleeve 5, and a locking cap 112 threadedly matched with the elastic locking pieces 111. The plurality of elastic locking pieces 111 are arranged in an array around the axis of the mounting sleeve 5, and a notch adapted to the mounting sleeve 5 is provided at the lower end of the elastic locking piece 111, and the elastic locking piece 111 is clamped and fixed on the mounting sleeve 5 through the notch. By tightening the locking cap 112, the elastic locking pieces 111 can be retracted inward, so that the mounting sleeve 5 and the transducer rod 1 are fixedly locked, and accurate measurement is ensured.
[0041] In this embodiment, if Figure 1 , 2 As shown in Figure 4, the transverse movement mechanism 9 includes a mounting seat 91 and a mounting block 92, wherein the mounting seat 91 is fixedly mounted on the side of the hull 4, and the length direction of the mounting seat 91 extends in the transverse direction, the mounting block 92 connects the mounting sleeve 5 and the mounting seat 91, and the mounting block 92 is slidably arranged on the mounting seat 91 in the transverse direction. In this way, the mounting sleeve 5 can slide in the transverse direction to adjust the position.
[0042] Specifically, a sliding groove 93 that moves in the lateral direction is provided on the side of the mounting seat 91 facing away from the mounting block 92. The size of the mounting block 92 is adapted to the sliding groove 93, and the mounting block 92 is slidably arranged in the sliding groove 93. In addition, preferably, a first curved surface 94 is provided on the inner wall of the sliding groove 93, and a second curved surface 95 that is adapted to the first curved surface 94 is provided on one end of the mounting block 92 that faces the hull 4. The first curved surface 94 is a semicircular shape that protrudes outward, and the corresponding second curved surface 95 is a semicircular shape that is concave inward. In this way, the friction between the mounting block 92 and the sliding groove 93 can be reduced by using the first curved surface 94 and the second curved surface 95 to cooperate.
[0043] Preferably, in this embodiment, a ball 96 is provided between the bottom surface of the sliding groove 93 and the mounting block 92. On the one hand, the ball 96 can reduce friction, and on the other hand, it can prevent the mounting block 92 from disengaging from the sliding groove 93 to a certain extent.
[0044] Specifically, a groove extending transversely is formed on the bottom surface of the sliding groove 93 at the position corresponding to the ball 96, and the cross-section of the groove is a semi-circular structure adapted to the ball 96. A semi-circular notch adapted to the ball 96 is formed at the lower end of the mounting block 92 at the position corresponding to the ball 96, and the ball 96 is clamped in the notch and slides along the groove following the mounting block 92.
[0045] In this embodiment, the sliding groove 93 is a straight groove. Preferably, the lateral movement mechanism 9 further includes a driving mechanism. The driving mechanism includes a driving screw 97 rotatably arranged in the sliding groove 93. The length direction of the driving screw 97 extends transversely, and the mounting block 92 is threadedly connected to the driving screw 97. In this way, the driving screw 97 and the mounting block 92 form a lead screw-nut mechanism. By rotating the driving screw 97, the mounting block 92 can be driven to slide along the sliding groove 93 to achieve position adjustment. At the same time, due to the limitation of the driving screw 97, the mounting block 92 can be prevented from falling off the sliding groove 93.
[0046] In other embodiments, when meeting the actual use requirements, the driving mechanism may not be provided. At this time, to prevent the mounting block 92 from slipping out of the sliding groove 93, the sliding groove 93 can be divided into two sections from the inside to the outside, and the width of the inner section is greater than that of the outer section. The shape of one end of the mounting block 92 facing the sliding groove 93 is adapted to the shape of the sliding groove 93, and its end facing the mounting seat 91 is a large-head end adapted to the inner section of the sliding groove 93. The large-head end is used to block and prevent falling off. And at this time, the mounting seat 91 can be designed as an annular structure or an arc-shaped structure that wraps the outside of the hull 4, so that the mounting sleeve 5 can slide along the side contour of the hull 4, increasing the position adjustment range and improving practicality.
[0047] Specifically, one end of the driving screw 97 extends out of the mounting seat 91 and is provided with a driving handle 98 to drive the driving screw 97 to rotate by using the driving handle 98. Of course, in other embodiments, a driving motor can also be used to drive the driving screw 97 to rotate.
[0048] In this embodiment, as Figure 5 、 6 shown, the mounting sleeve 5 is attached to the side of the mounting block 92 facing away from the mounting seat 91. The flipping mechanism 10 includes a hinge 101 provided on the outer circumference of the mounting sleeve 5 and the upper end of the mounting block 92. The rotating shaft of the hinge 101 constitutes the rotating shaft of the flipping mechanism 10. The two leaves of the hinge 101 are fixed to the circumferential surface of the mounting sleeve 5 and the upper end of the mounting block 92 respectively through fixing bolts 102.
[0049] Preferably, in this embodiment, as Figure 6 shown, the upper end surface of the mounting base 91 is higher than the upper end surface of the mounting block 92, and the height difference between the upper end surface of the mounting base 91 and the upper end surface of the mounting block 92 is adapted to the closing thickness of the hinge 101. In this way, after the mounting sleeve 5 is turned to the horizontal state by the turning mechanism 10, the peripheral surface of the mounting sleeve 5 can be attached to the upper end surface of the mounting base 91, and the mounting base 91 is used for bearing, so as to improve stability and safety.
[0050] Working process of the present application: When performing underwater measurement, turn over the mounting sleeve 5 so that the peripheral surface of the mounting sleeve 5 is attached to the side surface of the mounting block 92 facing away from the mounting base 91, so that the mounting sleeve 5 is in a vertical state, and keep the centers of the GNSS receiver 2, the transducer rod 1 and the transducer 3 on the same vertical line.
[0051] First, install the transducer 3 at the initial position. Under the initial position condition, the draft of the transducer 3 is 20 cm. Adjust the fixing pin 6 into the specific adjustment hole 51, and screw in the locking cap 112 to complete the locking and fixing of the transducer rod 1.
[0052] When encountering high waves or strong currents, it is necessary to lower the transducer 3. At this time, loosen the locking cap 112, press the fixing pin 6 so that the fixing pin 6 retracts into the fixing hole 110, lower the adjusting rod to the specified depth according to the actual water condition. After the fixing pin 6 corresponds to the specific adjustment hole 51, the fixing pin 6 pops out under the action of the spring 8 to complete the fixing, and then lock the locking cap 112.
[0053] Since during the test, the GNSS receiver 2 and the transducer 3 are coaxial, at this time, the height value of the measurement center of the transducer 3 can be obtained by subtracting the height of the transducer rod 1 from the elevation measured by the GNSS receiver 2. Through the conversion of the water depth data, the elevation value of the underwater topographic measurement point can be obtained in real time.
[0054] Meanwhile, during the test, according to the actual underwater conditions, by rotating the driving handle 98, the transducer 3 can be driven to move horizontally in the horizontal plane, so as to avoid obstacles and prevent damage caused by collision with sundries. Moreover, the turning mechanism 10 can be used. When the underwater conditions are complex and unsuitable for operation, the transducer 3 can be turned over to expose it above the water surface to avoid damaging the transducer 3 and reduce the operation risk.
[0055] After the test is completed, the transducer 3 can be driven to expose above the water surface by turning over the mounting sleeve 5, and the mounting sleeve 5 can be leaned against the mounting base 91 to complete the recovery.
[0056] In summary, for the fixing device of the present utility model, during measurement, the installation sleeve 5 remains in a vertical state. The transducer rod 1 is slidably installed in the installation sleeve 5, and the draft depth of the transducer 3 at the lower end of the transducer rod 1 can be adjusted to meet the measurement requirements of different water depths. When encountering conditions such as high waves or strong currents, the transducer 3 can be lowered in a timely manner to improve the accuracy and precision of the measurement.
[0057] At the same time, under the action of the lateral movement mechanism 9, the installation sleeve 5 can move horizontally in the horizontal direction, which is convenient for adjusting the azimuth of the transducer 3 in a complex river channel environment. Cooperating with the flipping of the flipping mechanism 10 and the lifting of the transducer 3, the risk of collision between the transducer 3 and aquatic plants, reefs, etc. can be reduced, adapting to the measurement of various hydrological conditions. The installation sleeve 5 can also drive the transducer 3 in and out of the water surface by using the flipping mechanism 10. When not measuring, the transducer 3 can be exposed above the water surface to improve safety. By using the GNSS receiver 2, on the one hand, the measurement position can be located, and on the other hand, it is convenient to obtain the height value of the transducer 3 to ensure the measurement accuracy.
[0058] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
[0059] In the description of the embodiments of the present application, it should be noted that if terms such as "upper", "lower", "horizontal", "inner", etc. are used to indicate the orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invention product is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0060] In addition, if the term "horizontal" appears, it does not mean that the component is required to be absolutely horizontal, but it can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but it can be slightly inclined.
