Description

Technical Field

[0001] The invention relates to a mounting device, in particular to a hoisting device for an echo sounder. Background Art

[0002] At present, an echo sounder is an instrument that emits sound waves in the water through a transducer. When the sound waves encounter obstacles and are reflected back to the transducer, the distance between the obstacle and the transducer can be obtained based on the time it takes for the sound waves to travel back and forth and the speed of the sound waves in the measured water area. When installing an echo sounder, it is usually installed on a ship through a support frame and at least 30 cm below the water surface. However, the existing echo sounder itself is heavy, and it is also subject to water resistance after entering the water surface, resulting in a large amount of power required to swing the echo sounder to a suitable position, and more operators are required to cooperate in the installation.

[0010] Furthermore, the connecting plate includes a first vertical section, a bending section and a second vertical section which are connected in sequence; the second vertical section is used to abut against the limiting column; and the third mounting plate is mounted on the first vertical section.

[0011] Furthermore, a fourth mounting plate is fixed to the bottom of the connecting rod; two mounting positions are arranged on the fourth mounting plate; and the mounting positions are used to connect to the echo sounder.

[0012] Furthermore, the echo sounder hoisting device also includes a protective cover; the protective cover is used to cover the outside of the echo sounder; the surface of the protective cover facing away from the echo sounder is formed into an arc surface.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] like Figure 1-2An echo sounder hoisting device shown in the figure includes a fixing frame 10, a locking member 20, a connecting rod 30 and a locking structure 40; the fixing frame 10 is provided with a mounting groove capable of accommodating the connecting rod 30, and the mounting groove also has a side notch for the connecting rod 30 to enter and exit; the fixing frame 10 is also provided with a U-shaped pivot groove 60 with an upper notch; the connecting rod 30 is used to install the echo sounder 70, and is fixed with a rotating shaft 80 capable of pivoting with the U-shaped pivot groove 60; the locking member 20 is used to abut against the surface of the connecting rod 30 facing the side notch when the connecting rod 30 is placed, so as to prevent the connecting rod 30 from escaping from the mounting groove from the side notch; the locking structure 40 is used to detachably fix the locking member 20 to the fixing frame 10.

[0029] Thus, when the echo sounder 70 is installed on the ship 140 using the echo sounder hoisting device, the fixing frame 10 is installed on the ship 140, and the echo sounder 70 is installed on the bottom end of the connecting rod 30; the connecting rod 30 is tilted and placed in the installation groove. At this time, the connecting rod 30 is not parallel to the extension direction of the installation groove (such as Figure 2 The connecting rod 30 is then pushed downward to slide the rotating shaft 80 on the connecting rod 30 into the U-shaped pivot groove 60. At this time, the cooperation between the rotating shaft 80 and the U-shaped pivot groove 60 prevents the connecting rod 30 from continuing to move downward relative to the fixing frame 10. Then, by using the lever principle, the connecting rod 30 is rotated with the rotating shaft 80 as the rotation point, and the connecting rod 30 can be easily rotated into the installation groove, which can reduce the number of operators. At this time, the connecting rod 30 is parallel to the extension direction of the installation groove (such as Figure 2 The connecting rod 30 is then abutted against the locking member 20 and fixed to the fixing frame 10 with the locking structure 40, so that the connecting rod 30 can be fixed in the installation groove to prevent it from rotating relative to the fixing frame 10. In this way, the echo sounder 70 can be smoothly moved to the specified specific position, and the operation is convenient.

[0030] It should be noted that when installing the hoisting device of this echo sounder, Figure 3 As shown, the echo sounder hoisting device can be installed at the bow 141 or the hull 142. Figure 3It can be seen that, since the echo sounder has a wider emission range when emitting sound waves, the hull 142 is in an arc shape, which can reduce the obstruction of the bow 141 in space to the echo sounder 70 emitting sound waves. In this way, the echo sounder can be installed at a position greater than or equal to 30m below the horizontal plane H1 to ensure the emission of sound waves by the echo sounder. When installed at the hull 142, the echo sounder needs to be installed at a position greater than or equal to 30m below the bottom surface H2 of the ship 140. At this time, the length of the connecting rod 30 is lengthened. Therefore, in this embodiment, it is preferred to install the echo sounder lifting device at the bow 141, which can shorten the length of the connecting rod 30. Further, the length of the connecting rod 30 under the rotating shaft 80 is shortened. It can be seen from the lever principle that the power for rotating the connecting rod 30 can be reduced at this time, making the rotation easier.

[0031] Specifically, a first mounting plate 90 is provided on the fixing frame 10, and a first mounting hole 91 is opened on the first mounting plate 90, so that the fixing frame 10 can be detachably mounted on the boat 140 by passing a screw through the first mounting hole 91, and the disassembly and assembly are convenient.

[0032] Specifically, the locking member 20 includes a collision rod 21 and two connecting plates 22; the two connecting plates 22 are arranged at intervals and in parallel; the two ends of the collision rod 21 are respectively fixedly connected to the two connecting plates 22; the collision rod 21 is used to abut against the connecting rod 30; more specifically, after the echo sounder lifting device is assembled, the two connecting plates 22 are located on the outer sides of the opposite sides of the fixing frame 10, that is, the fixing frame 10 is placed between the two connecting plates 22.

[0033] Furthermore, the locking structure 40 includes a locking nut, a locking screw, a second mounting plate 41 fixed to the upper end of the fixing frame 10, and a third mounting plate 42 fixed to the connecting plate 22; a second mounting hole is provided on the second mounting plate 41; a third mounting hole is provided on the third mounting plate 42; the rod of the locking screw can pass through the second mounting hole and the third mounting hole, and be threadedly connected with the locking nut; the second mounting plate 41 is fixed to the upper end of the fixing frame 10, so that the second mounting plate 41 can be relatively far away from the sea surface during installation, that is, the second mounting plate 41 is located at a higher position and is convenient for personnel to operate; furthermore, the arrangement of the locking nut, the locking screw, the second mounting hole and the third mounting hole is adopted to facilitate disassembly and assembly.

[0034] To further fix the locking piece 20, preferably, the locking structure 40 also includes a limiting column 43 fixed to the lower end of the fixing frame 10; when the locking piece 20 is fixed on the fixing frame 10, the limiting column 43 can collide with the surface of the connecting plate 22 facing the same direction as the side notch, that is, the locking piece 20 is fixed, and the locking piece 20 is moved to a position collided with the limiting column 43, and then the locking piece 20 is fixed with a locking screw and a locking nut. At this time, the limiting column 43 can prevent the locking piece 20 from moving in a direction away from the fixing frame 10, thereby further improving the stability of the installation of the locking piece 20, that is, improving the installation stability of the echo sounder 70.

[0035] Furthermore, there are two groups of locking structures 40 , and the two groups of locking structures 40 are arranged in a one-to-one correspondence with the two connecting plates 22 , that is, both sides of the locking member 20 are fixed to the fixing frame 10 , thereby improving the installation stability of the fixing frame 10 .

[0036] Specifically, the connecting plate 22 includes a first vertical section 221 , a bending section 222 and a second vertical section 223 which are connected in sequence; the second vertical section 223 is used to abut against the limiting column 43 ; and the third mounting plate 42 is mounted on the first vertical section 221 .

[0037] The existing single support frame 120 for installing the echo sounder 70 can only install a single echo sounder 70. When two or more echo sounders 70 need to be installed, two or more support frames 120 need to be installed. If the ship 140 is small, the installation of the double support frames 120 will cause the ship 140 to be subjected to unbalanced force during the driving process, which greatly reduces the stability of the ship 140 during driving. However, since the present echo sounder hoisting device reduces the power when installing the echo sounder 70, on the basis of ensuring safety, the present echo sounder hoisting device can also be used to install two echo sounders 70 at the same time; specifically, a fourth mounting plate 100 is also fixed to the bottom of the connecting rod 30; two mounting positions are arranged on the fourth mounting plate 100; the mounting position is used to connect with the echo sounder 70, specifically, an existing flange can be arranged at the mounting position, and the echo sounder 70 is installed on the mounting position through the flange.

[0038] Preferably, the echo sounder hoisting device also includes a protective cover 110; the protective cover 110 is used to cover the outside of the echo sounder 70. Specifically, the protective cover 110 is provided on the surface of the echo sounder 70 facing the same direction as the movement of the ship 140 to prevent the echo sounder 70 from being impacted by the water flow when the echo sounder 70 moves with the ship 140; more preferably, the surface of the protective cover 110 facing away from the echo sounder 70 is formed as an arc surface to reduce the water flow resistance.

[0039] Due to the resistance of water flow and the like, the fixing frame 10 and the like are easily deformed. In order to reduce the deformation, preferably, the echo sounder lifting device also includes a support frame 120; the support frame 120 includes a first support plate 121, a second support plate 122, and support columns 123 whose two ends are respectively fixedly connected to the first support plate 121 and the second support plate 122; the first support plate 121 is fixedly connected to the fixing frame 10; the second support plate 122 is used to abut and fit with the hull 142 at the bow 141, so that the fixing frame 10 can be supported by the first support plate 121, the second support plate 122 and the support column 123, thereby reducing the possibility of deformation of the support frame 120; specifically, when the echo sounder lifting device is installed at the bow 141, the second support plate 122 is configured to be a structure that can match and fit with the hull 142 at the bow 141.

[0040] Furthermore, the echo sounder lifting device also includes an extension rod 130; a mounting flange 50 is fixed to the top end of the connecting rod 30; the extension rod 130 can be inserted into the mounting hole of the mounting flange 50. At this time, the extension rod 130 is inserted into the mounting hole of the mounting flange 50, and the operator's force acts on the extension rod 130 to realize the rotation of the connecting rod 30. It can be seen from the lever principle that at this time, the required power is further reduced, and the installation is further made more labor-saving and convenient.

[0041] In this embodiment, the stress of the hoisting device of the echo sounder in use is also analyzed. In the actual production and use of the product, the connecting rod 30 is supported by a stainless steel 316 steel pipe with an outer diameter of 80 mm, a wall thickness of 6 mm, and a length of about 2 m. In the actual product, the deadweight of the connecting rod is 20 kg, and the gravity of the echo sounder 70 is about 1000 N. Specifically:

[0042] like Figure 4-5 As shown, in the use state, the force of the connecting rod 30 is analyzed: the connecting rod 30 is subjected to its own weight F1=20kg, the gravity of the echo sounder 70 F2=1000N, the underwater resistance F3=5000N when the forward speed of the ship 140 is 5 m / s, and it is also subjected to the constraint force F4 of the fixing frame 10 and the rotating shaft 80. The finite element force analysis software is used to obtain that the maximum stress at the top of the connecting rod 30 is 85.6MPa, and the maximum stress at the bottom of the connecting rod is 112.2MPa, both of which meet the allowable stress of stainless steel of 410MPa; at the same time, the maximum deformation of the bottom of the connecting rod 30 is 2.32mm. For the stainless steel connecting rod 30 with a length of about 2m, such a small deformation does not affect its normal measurement and use.

[0043] like Figure 1 and Figure 6As shown, the force on the locking member 20 is analyzed. The locking member 20 is installed on the fixing frame 10 through the locking screw of the locking structure 40, and the locking member 20 abuts against the limiting column 43 of the locking structure 40, that is, the locking member 20 mainly has the fixing constraint force F6 of the locking screw, the fixing constraint force F7 of the limiting column 43, and the force F5 on the locking member 20 against the rod 21 when the connecting rod 30 is stressed. The connecting rod 30 will only be subjected to a greater force impact when the ship 140 moves backward. When the backward speed of the ship 140 is 3m / s, the total force on the connecting rod 30 will reach 7000N. At this time, after analysis, the maximum stress on the locking member 20 is 226Mpa and the maximum deformation of the abutting rod 21 is 0.4mm. At this time, the locking member 20 is made of standard channel steel, and its strength can meet the normal use of the locking function.

[0044] like Figure 7 As shown, the fixing frame 10 is made of stainless steel 316, and the force of the fixing frame 10 is analyzed. The fixing frame 10 is fixedly installed on the ship 140 by screws; the stress concentration parts of the fixing frame 10 are mainly at the contact position between the bottom of the connecting rod 30 and it and the contact position between the rotating shaft 80 and it. At this time, the rotating shaft 80 on the connecting rod 30 is subjected to a force F8=5200N (including the weight of the echo sounder hoisting device and the echo sounder 70 as well as the force when the ship 140 moves forward), and the thrust F9 of the connecting rod 30 is 9200N, that is, the fixing frame 10 is mainly subjected to the above-mentioned force F8 and thrust F9. At this time, after analysis and measurement, the maximum deformation at the position of the U-shaped pivot groove 60 is less than 0.5mm, so it does not affect normal use. The fixing frame 10 has good rigidity and a small overall deformation, which can meet the fixed support requirements of the connecting rod 30.

[0045] like Figure 8 As shown, the first support plate 121 and the support column 123 are connected by welding, and the support frame 120 is made of channel steel. In order to better perform force analysis and comparison, we selected 5#, 6#, and 8# channel steels for comparative analysis; specifically, the force analysis of the support frame 120 is performed, and the thrust F10=15000N is exerted on the support frame 120. The thrust is mainly concentrated at the welding position of the first support plate 121 and the support column 123. At this time, the maximum stress of the 8# channel steel with a specification of 80*43*5mm is 103.3MPa; the maximum stress of the 6# channel steel with a specification of 60*34*4.5mm is 113.13PMa; the maximum stress of the 5# channel steel with a specification of 50*38*4.3mm is 112.1MPa.

[0046] In summary, compared with 8# channel steel, the stress of 5#6# support is increased, while the cross-sectional area of ​​5#6# is not much different. Therefore, when selecting channel steel, try to choose larger size specifications above 5#.

[0047] Through analysis, it was also found that Figure 2 The support column 123 ( Figure 2 The setting of the inclined direction of the component indicated by the middle number a) relative to the first support plate 121 also has a certain difference in the force it is subjected to. When the support column 123 is inclined downward relative to the first support plate 121, the bearing stress at the welding point is greatly reduced.

[0048] In summary, the feasibility of the echo sounder hoisting device has been theoretically confirmed through force analysis.

[0049] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
