[0023] The structure of the utility model will be further described below in combination with the drawings and through embodiments. It should be noted that the embodiments are narrative rather than limiting.

[0024] A low-coupling and high-splicing-strength building block type structure of a marine operation equipment, please see Figures 1-8 The invention point is:

[0025] 1. The marine operation equipment is designed to form multiple independent functional modules, which reduces the difficulty of cable separation and realizes low coupling combination of the functional modules.

[0026] 1) The information interaction relationship of each functional module is constructed, the complex cable connection between the functional modules is designed to be close to each other, six functional units are designed, including a paper chart drawing unit 1, a control unit 2, a main control unit 3, a display control unit 4, a support assembly 5 and a paper chart drawer unit 6, so that the connection cables between the functional modules in each functional unit become “internal cables”, when the functional units of the device are disassembled and assembled, the “internal cables” do not need to be separated, which greatly reduces the difficulty of separating the cables and structures of the functional units of the device, as shown in Figure 1 、 2 .

[0027] 2) The paper chart drawing unit 1 and the paper chart drawer unit 6, the control unit 2 and the main control unit 3 are respectively fixed and connected after being overlapped, and form a left paper chart operation area and a right electronic case area, the support assembly 5 is fixed on the equal height surface of the two areas, and the display control unit 4 is fixed on the support assembly 5. Since the structure size of the right electronic case area meets the condition of entering the cabin of the actual ship, it can not be physically separated, and the connection cables between the control unit 2 and the main control unit 3 also become “internal cables”, further reducing the difficulty of separating the cables of the device. As shown in Figure 3 .

[0028] 3) The paper chart drawing unit 1 needs to interact with the control unit 2 and the main control unit 3, and the cable separation point is designed at the paper chart drawing unit 1, so that only the plug and the socket of the connector at the paper chart drawing unit 1 need to be separated, and the cables of the paper chart drawing unit 1 can be separated from the control unit 2 and the main control unit 3. As shown in Figure 1 .

[0029] 4) The display control unit 4 needs to interact with the control unit 2 and the main control unit 3, and the support assembly 5 is the installation carrier of the interactive cable, one end of the interactive cable is connected with the display control unit 4, and the other end of the interactive cable is connected with the KVM module of the control unit 2, the switch of the main control unit 3 and the power module respectively. The cable separation point at one end is designed at the display control unit 4, and the cable separation point at the other end is designed at the KVM module of the control unit 2, the switch of the main control unit 3 and the power module respectively. In this way, after the plug and the socket of the connector at the display control unit 4 are separated, the cable at one end of the display control unit 4 can be separated from the support assembly 5, and after the plug and the socket of the connector at the KVM module of the control unit 2, the switch of the main control unit 3 and the power module are separated, the cable of the support assembly 5 can be separated from the control unit 2 and the main control unit 3. As shown in Figure 1 .

[0030] 5) Paper chart drawer unit is used to store paper charts, and no information interaction is required with other functional units, only structural separation is needed. As shown in Figure 4 .

[0031] 2, Connection design of upper and lower overlapping functional units

[0032] 1) Right angle double side four-point positioning design is adopted. As shown in Figure 5 , on the mutually perpendicular edges A and B of the lower overlapping surface, two groups of positioning surfaces (achieved by designing positioning blocks) are designed to extend vertically upward, the coplanar positioning surface 1 and positioning surface 2 and the positioning surface 3 and positioning surface 4 are respectively used as the limiting surfaces of the two directions of the upper functional unit. Thus, as shown in Figure 5 , when the upper functional unit is placed on the lower functional unit, the upper functional unit is only needed to be pushed left and right and forward and backward, so that the bottom vertical surface C and the bottom vertical surface D of the upper functional unit are respectively tightly attached to the coplanar positioning surface 1 and positioning surface 2 and the positioning surface 3 and positioning surface 4, so as to achieve the accurate positioning of the upper and lower overlapping functional units.

[0033] 2) Rotating embedded locking and external hidden operation scheme is adopted. As shown in Figure 7 and Figure 8 , for the joint of the upper and lower functional units, a lower connecting block is fixed inside the lower functional unit box by screws, an axle hole is provided on the lower connecting block, a hook piece is provided on the inner side of the lower connecting block, a driving shaft fixed vertically on the hook piece is inserted and fitted with the axle hole of the lower connecting block, a driving shaft hole is coaxially provided at the center of the driving shaft, the driving shaft hole is a hexagonal hole, and an operation hole capable of inserting a hidden screw is provided on the side wall of the lower functional unit box corresponding to the position of the driving shaft hole. An upper connecting block is fixed inside the upper functional unit box by screws, and a pin shaft is fixed vertically on the inner side of the upper connecting block. After the hidden screw is loosened, a driving tool is inserted into the driving shaft hole from the outside to drive the hook piece to rotate around the center of the driving shaft, the upper end of the hook head of the hook piece hooks the pin shaft, and the locking connection of the upper and lower functional units is achieved.

[0034] 3) The force state of the hook piece when rotating and embedding the pin shaft is shown in Figure 6 , the component force F is opposite to the positioning surface 3. If the component force F points to the positioning surface 3, the bottom vertical surface D of the upper functional unit will be separated from the positioning surface 3, causing the misalignment of the upper and lower overlapping functional units. Therefore, to avoid this phenomenon, the rotating direction of the hook piece (the rotating direction during the hooking cooperation with the pin shaft) needs to be opposite to the positioning surface. As shown in Figure 5 and 6 , the rotating directions of the hook pieces 1 and 2 are opposite to the positioning surfaces 3 and 4, and the rotating directions of the hook pieces 3 and 4 are opposite to the positioning surfaces 1 and 2.

[0035] 4) The left work area and the right case area, the support assembly 5 and the two areas, the display control unit 4 and the support assembly 5 are all fixed by non-extruding screws, and the non-extruding screw fixed design is not the key point of the present application.

[0036] 3. Analysis and calculation of the connection strength of the upper and lower overlapping functional units.

[0037] The locking mechanism composed of a hook member and a pin shaft is made of high-quality carbon steel, and the allowable shear stress of the material [τ] = 0.3σ = 300 N / mm 2 , and the diameter of the pin shaft is 10 mm.

[0038] 1) Selection of maximum dynamic load

[0039] The failure type of the marine operation equipment is fatigue damage caused by vibration and over-stress damage caused by impact. The design method is designed according to the maximum impact force. The crash safety test is a half-sine wave, the peak acceleration A = 30g, the pulse width D = 11ms, and 2.5 times the peak acceleration value of the strong impact is used as the maximum dynamic load for design input.

[0040] 2) Selection of the number of locking mechanisms

[0041] According to the size and length of each functional unit, the locking mechanisms are arranged uniformly, and the number selection principle is as follows:

[0042]

[0043] In the formula, n is the number of locking mechanisms;

[0044] l is the structural length dimension.

[0045] The effective depth of the marine operation equipment is 845mm, the width of the left paper chart operation area is 1200mm, and the width of the right electronic case area is 600mm. Therefore, two groups of locking mechanisms are arranged on the inner surface of the case between each layer in the left paper chart operation area, two groups of locking mechanisms are arranged on the left and right sides of the combination of the control unit 2 and the main control unit 3, and one group of locking mechanisms is arranged on the rear part.

[0046] 3) Step of checking the shear strength of a single locking mechanism

[0047] After the hook member is rotated and embedded in the pin shaft locking, the pin shaft bears a large shear force in the vertical direction of the equipment. In general, satisfying the shear strength requirement will necessarily satisfy the tensile strength requirement, so only the shear strength checking needs to be performed.

[0048] The maximum dynamic load of a single locking mechanism is:

[0049] Fmax = (2.5) AM

[0050] Wherein A - peak acceleration

[0051] M - the mass of the device allocated to a single locking mechanism.

[0052] The heaviest functional unit in the left paper chart operation area is the paper chart plotting unit 1, with a weight of 129 Kg, and the weight allocated to a single locking mechanism is 21.5 Kg. In the right electronic chassis area, the weight of the control unit 2 is 84 Kg, and the weight allocated to a single locking mechanism is 16.8 Kg. Thus, it is calculated that:

[0053] F1max = 2.5 x 30g x 21.5 / g = 1612.5N

[0054] F2max = 2.5 x 30g x 16.8 / g = 1260N

[0055] The maximum allowable shear dynamic load of a single locking mechanism is:

[0056]

[0057] Wherein [τ] - the allowable shear stress of the material;

[0058] S - the effective shear area of the pin shaft;

[0059] D - the diameter of the pin shaft.

[0060] Thus, it is calculated that: [Fmax] = 300 x 78.54 = 23562N

[0061] F1max and F2max are much smaller than [Fmax], so the upper and lower overlapped functional units have good anti-vibration and impact performance.

[0062] 4. Splitting and assembling of the functional units of the application

[0063] The splitting process of the navigation operation equipment is as follows:

[0064] 1) Separate the connector at the display and control unit 4, loosen the fastener connecting the display and control unit 4 and the support assembly 5, and separate them;

[0065] 2) Separate the connectors at the KVM module of the control unit 2, the switch and the power module of the main control unit 3, loosen the fastener connecting the support assembly 5 and the isometric surface, and peel off the cable connection between the support assembly 5 and the control unit 2 and the main control unit 3, and separate them from the main body;

[0066] 3) Separate the connector at the paper chart plotting unit 1, loosen the fastener connecting the left paper chart operation area and the right electronic chassis area, and separate the two areas;

[0067] 4) Outside the equipment, using a driving tool, loosen the hidden screw, pass through the hidden operation hole, rotate the hook part inside the paper chart drawer unit 6 box, make it separate from the pin shaft inside the paper chart drawing unit 1 box, so as to realize the separation of the paper chart drawer unit 6 and the paper chart drawing unit 1;

[0068] 5) The same as the method of 4), the paper chart drawer unit 6 is disassembled. The reverse operation can be completed in the assembly process.

[0069] 5, test verification

[0070] The design method of the low-coupling and high-splicing-strength building block type structure of the marine operation equipment of the application has developed a prototype and equipment, which has passed the vibration and impact test and can be completed in 30 minutes through actual operation.

[0071] Although the embodiments and drawings of the application are disclosed for the purpose of illustration, those skilled in the art can understand that various substitutions, changes and modifications are possible without departing from the spirit of the application and the appended claims, therefore, the scope of the application is not limited to the contents disclosed in the embodiments and drawings.
