Description

Technical Field

[0001] The invention belongs to the technical field of foot buckles, and in particular relates to a disassembly-free embedded foot buckle for ship equipment. Background Art

[0002] Since ships are prone to shaking during navigation, during the installation of ship equipment (referring to various types of machinery, instruments, facilities and systems installed on the ship), it is often necessary to use foot clips to firmly fix the ship equipment to the hull or other parts of the ship, so as to provide stronger stability for the ship equipment and reduce external interference and looseness problems during long-term use.

[0003] However, the existing foot buckles usually have the following technical problems when installing ship equipment:

[0004] When disassembling and repairing ship equipment and tripods, workers need to spend a long time manually disassembling the tripods, which not only increases the workload of workers, but also requires careful operation to ensure that the safety equipment is not damaged. In addition, due to factors such as waves and wind, the hull is in a state of constant shaking, making manual disassembly more difficult and dangerous, further increasing the difficulty of operation and potential safety hazards;

[0005] After the installation of ship equipment is completed, the hull is in a state of constant shaking, which will cause frequent hard collisions between the foot buckles and the mounting holes, causing the structure of the foot buckles themselves to be impacted, deformed, cracked or damaged, affecting the safety and service life of the foot buckles, and further resulting in a loose connection between the foot buckles and the mounting holes, increasing the risk of loosening, affecting the normal operation of the ship equipment, and even posing a threat to the safety of the ship.

[0017] Compared with the existing technology, the advantages of the non-disassembly embedded foot buckle for ship equipment are:

[0018] 1. The present invention provides a locking mechanism, so that when the ship equipment and the columnar foot buckle need to be disassembled and repaired, the clamping mechanism no longer clamps and fixes the equipment connecting seat, and the ship equipment is removed from the mounting seat, so that the placement plate automatically moves upward in the mounting frame under the elastic force of the reset spring, and further pulls the wedge block into the slide groove through the pull rope, so that the wedge block is no longer clamped on the fixing platform. At this time, the staff can pull the columnar foot buckle out of the fixing platform by themselves, so as to realize the disassembly-free removal of the foot buckle, and the staff does not need to manually disassemble the foot buckle, which is convenient to operate, reduces the workload and improves the safety hazard.

[0019] 2. The present invention provides a buffer mechanism. After the columnar foot buckle is installed, a plurality of arc-shaped buffer plates can tightly contact the peripheral side walls of the columnar foot buckle under the action of the magnetic repulsion between the first electromagnet and the second electromagnet. When the hull shakes, the slider can move in the buffer groove to avoid frequent hard collisions between the columnar foot buckle and the mounting hole, thereby increasing the service life of the columnar foot buckle and reducing the risk of looseness between the columnar foot buckle and the mounting hole, thereby ensuring the normal operation of the ship equipment.

[0020] 3. The present invention sets an adjustment mechanism. During the installation of the ship equipment, the placement plate, the mounting seat and the ship equipment installed thereon will squeeze the hydraulic oil in the installation frame. The ship equipment of different weights has different squeezing forces on the hydraulic oil, so the hydraulic pressure of the hydraulic oil is different. When the weight of the ship equipment changes, the annular hydraulic sensor can transmit different pressure signals to the control system, and control the rotation degree of the rotating rod through the control system, so as to automatically adjust the buffering capacity of the columnar foot buckle and the ship equipment according to the weight of the ship equipment, thereby ensuring the buffering effect of the ship equipment and improving the stability of the ship equipment.

[0021] 4. The present invention sets a compensation mechanism. After long-term use, the pressure sensor is turned on. When the pressure sensor detects that the force of the magnetic repulsion force applied to the side wall of the columnar foot buckle is reduced compared to when the ship equipment is just installed, the control system can adjust the extension of the electric telescopic rod according to the pressure information measured by the pressure sensor, so that the piston push block in the compensation groove is close to the columnar foot buckle, so that the magnetic repulsion force between the second electromagnet and the first electromagnet is increased, thereby automatically compensating for the buffering capacity of the first electromagnet and the second electromagnet when the magnetism degrades, thereby greatly extending the service life of the first electromagnet and the second electromagnet, and ensuring the buffering capacity of the magnetic repulsion force between the first electromagnet and the second electromagnet for the columnar foot buckle.

DETAILED DESCRIPTION

[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0031] Example: Refer to Figures 1 to 7 , a non-disassembly embedded foot buckle for ship equipment, comprising:

[0032] A fixing platform 1, a mounting frame 2 and a device connection seat 3, wherein the mounting frame 2 is arranged above the fixing platform 1, a placing plate 21 is airtightly and slidably connected inside the mounting frame 2, a mounting seat 22 is fixedly connected to the upper end of the placing plate 21, two groups of symmetrically arranged clamping mechanisms 4 are arranged on the mounting seat 22, and the device connection seat 3 is mounted on the mounting seat 22 through the clamping mechanisms 4;

[0033] Specifically, the clamping mechanism 4 includes a support plate 41 fixedly connected to the side wall of the mounting seat 22, a hydraulic cylinder 42 is fixedly connected above the support plate 41, and a clamping frame 43 is fixedly connected to the output end of the hydraulic cylinder 42. When the ship equipment is installed, the equipment connection seat 3 fixedly connected to the ship equipment is placed on the mounting seat 22, and then the clamping frames 43 on both sides are driven by the hydraulic cylinder 42 to clamp on both sides of the equipment connection seat 3 to achieve the installation and fixation of the ship equipment.

[0034] The locking mechanism 5 is used to install the installation frame 2 on the fixed platform 1. The locking mechanism 5 includes a columnar foot buckle 51 fixedly connected to the lower end of the installation frame 2. A mounting hole 52 with a diameter larger than that of the columnar foot buckle 51 is opened at the center position of the fixed platform 1. A limit ring 53 is fixedly connected to the position above the mounting hole 52 on the circumference of the columnar foot buckle 51. The diameter of the limit ring 53 is larger than the diameter of the mounting hole 52. A plurality of slide grooves 54 distributed in a circumferential array are opened on the circumference of the columnar foot buckle 51 below the mounting hole 52. A wedge block 55 is slidably connected in the slide groove 54. An ejection spring 56 is provided between the wedge block 55 and the inner wall of the slide groove 54. A pull rope 57 is fixedly connected to the wedge block 55. The other end of the pull rope 57 extends to the inside of the installation frame 2 and is fixedly connected to the bottom end of the placement plate 21. A reset spring 58 is provided between the placement plate 21 and the inner bottom wall of the installation frame 2.

[0035] In view of the problem in the prior art that when disassembling and repairing ship equipment and foot buckles, it takes a long time for workers to manually disassemble the foot buckles, the present invention provides a locking mechanism 5. When installing the ship equipment and the columnar foot buckle 51, the equipment connecting seat 3 is first installed on the mounting seat 22 through the clamping mechanism 4. At this time, the ship equipment will cause the placement plate 21 to move downward relative to the mounting frame 2 under the action of its own gravity, and further cause the mounting frame 2 and the columnar foot buckle 51 at the lower end to move downward. When the inclined surface of the wedge block 55 on the side wall of the columnar foot buckle 51 contacts the arc-shaped buffer sheet 63, it can be squeezed into the slide groove 54 by the arc-shaped buffer sheet 63, and when the limit ring 53 contacts the upper end of the fixed platform 1, the wedge block 55 is no longer affected by the arc-shaped buffer sheet 63, and is automatically moved out of the fixing platform 1 under the action of the elastic force of the reset spring 58. The columnar foot buckle 51 pops up from the slide groove 54 and contacts the lower wall of the fixing platform 1, so that the columnar foot buckle 51 can be embedded and connected in the fixing platform 1, and the installation and fixation of the columnar foot buckle 51 is automatically realized. When the ship equipment and the columnar foot buckle need to be disassembled and repaired, the clamping mechanism 4 no longer clamps and fixes the equipment connecting seat 3, and the ship equipment is removed from the mounting seat 22, so that the placement plate 21 can automatically move upward in the mounting frame 2 under the elastic force of the reset spring 58, and further pull the wedge block 55 into the slide groove 54 through the pull rope 57, so that the wedge block 55 is no longer connected to the fixing platform 1. At this time, the staff can pull the columnar foot buckle 51 out of the fixing platform 1 by themselves, so as to realize the disassembly-free removal of the columnar foot buckle 51, and the staff does not need to manually disassemble the columnar foot buckle 51. The operation is convenient, which reduces the workload and improves the safety hazards.

[0036] A buffer mechanism 6 is provided between the fixing platform 1 and the columnar foot buckle 51, which is used for buffering the columnar foot buckle 51 through magnetic repulsion after installation is completed to avoid hard collision. The buffer mechanism 6 includes a plurality of buffer grooves 61 distributed in a circular array and opened on the inner wall of the mounting hole 52. A slider 62 is slidably connected to the inner wall of the buffer groove 61. The side of the slider 62 close to the columnar foot buckle 51 is fixedly connected to an arc-shaped buffer sheet 63 through a connecting rod. A first electromagnet 64 is installed on the inner wall of the buffer groove 61. The side of the slider 62 close to the first electromagnet 64 is fixedly connected to the second electromagnet 65. The first electromagnet 64 and the second electromagnet 65 repel each other with the same poles when power is supplied.

[0037] In view of the problem in the prior art that the hull is in a state of constant shaking, which causes frequent hard collisions between the foot buckle and the mounting hole, causing the structure of the foot buckle itself to be impacted, deformed, cracked or damaged, and affecting the safety and service life of the foot buckle, the present invention sets a buffer mechanism 6. After the columnar foot buckle 51 is installed, a plurality of arc-shaped buffer sheets 63 can tightly contact the surrounding side walls of the columnar foot buckle 51 under the action of the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65. When the hull shakes, the columnar foot buckle 51 can overcome the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65, and push the slider 62 to move in the buffer groove 61, so that there is a certain buffer space between the columnar foot buckle 51 and the mounting hole 52, avoiding frequent hard collisions between the columnar foot buckle 51 and the mounting hole 52, thereby increasing the service life of the columnar foot buckle 51 and reducing the risk of looseness between the columnar foot buckle 51 and the mounting hole 52, thereby ensuring the normal operation of the ship equipment.

[0038] An adjusting mechanism 7 is also provided inside the fixed platform 1 for automatically adjusting the buffering capacity according to the weight of the ship equipment. The adjusting mechanism 7 includes an annular hydraulic sensor 71 installed on the inner bottom wall of the mounting frame 2. Hydraulic oil is provided between the placement plate 21 and the inner bottom wall of the mounting frame 2. The fixed platform 1 is provided with a plurality of groups of conductive sheet assemblies 72 controlled by the annular hydraulic sensors 71. The conductive sheet assemblies 72 are used to control the magnitude of the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65 at the corresponding position.

[0039] The conductive sheet assembly 72 includes a rotating rod 721 rotatably connected to the inside of the fixed platform 1, a first arc-shaped conductive sheet 722 is fixedly connected to the rotating rod 721, a second arc-shaped conductive sheet 723 is fixedly connected to the inside of the fixed platform 1, the first electromagnet 64 and the second electromagnet 65 are connected in series with the power supply device through the first arc-shaped conductive sheet 722 and the second arc-shaped conductive sheet 723, and the control system arranged inside the fixed platform 1 adjusts the rotation degree of the rotating rod 721 through the pressure information measured by the annular hydraulic sensor 71.

[0040] Specifically, the annular hydraulic sensor 71 here can adapt to the vibration environment during the operation of the hull, ensuring that more accurate and reliable measurement results can be provided.

[0041] Specifically, when the annular hydraulic sensor 71 is able to transmit the detected pressure signal to the control system, the control system here adopts a PID controller to analyze the received pressure signal, and determines the need to adjust the degree of rotation of the rotating rod 721 according to the set target pressure range. Here, the driving source of the rotating rod 721 is a commonly used servo motor, so it is not elaborated in detail here.

[0042] When the weight of the ship equipment is large, the equipment will generate a large inertial force during the movement of the ship. If the buffering capacity of the ship equipment is insufficient, the equipment will be damaged by vibration or impact. When the weight of the ship equipment is small, the equipment will generate a small inertial force during the movement of the ship. If the buffering capacity of the ship is too large, the ship equipment will be over-moved and vibrate or swing unnecessarily, which will further lead to the instability of the equipment fixation, thereby affecting the normal operation or accuracy of the ship equipment. In view of the above problems, the present invention can automatically adjust the buffering capacity of the columnar foot buckle 51 and the ship equipment according to the weight of the ship equipment by setting an adjustment mechanism 7, thereby ensuring the buffering effect of the ship equipment and improving the stability of the ship equipment. The specific adjustment method is as follows:

[0043] In the process of installing the ship equipment, the placement plate 21, the mounting seat 22 and the ship equipment installed thereon will squeeze the hydraulic oil in the mounting frame 2, and the ship equipment of different weights will squeeze the hydraulic oil with different strengths, so that the hydraulic pressure of the hydraulic oil is different. When the weight of the ship equipment changes, the annular hydraulic sensor 71 can transmit different pressure signals to the control system, and further control the rotation degree of the rotating rod 721 through the control system;

[0044] The magnetic repulsion between the first electromagnet 64 and the second electromagnet 65 can be achieved through the contact area between the first arc-shaped conductive sheet 722 and the second arc-shaped conductive sheet 723. The resistance value R of the circuit where the first electromagnet 64 and the second electromagnet 65 are located can be expressed by the following formula:

[0045] R = ρL / A;

[0046] Where: ρ is the resistivity of the material (unit: ohm·meter), L is the length of the conductor (unit: meter), A is the cross-sectional area of ​​the conductor (unit: square meters);

[0047] Since the resistivity ρ of the material remains unchanged, and since the width of the first arc-shaped conductive sheet 722 and the second arc-shaped conductive sheet 723 remains unchanged when they are in contact, the length of the conductor in the present invention remains unchanged;

[0048] It can be seen from the formula that the contact area A is inversely proportional to the resistance value R. Therefore, when the contact area between the first arc-shaped conductive sheet 722 and the second arc-shaped conductive sheet 723 is larger, the resistance value R of the circuit where the first electromagnet 64 and the second electromagnet 65 are located is smaller, and the current is larger;

[0049] According to the above conditions, when the weight of the ship equipment is relatively large, the rotation degree of the rotating rod 721 is large, and the contact area between the first arc-shaped conductive sheet 722 and the second arc-shaped conductive sheet 723 is relatively small, so that the resistance value of the circuit where the first electromagnet 64 and the second electromagnet 65 are located is relatively large, and the current is relatively small, so that when the weight of the ship equipment is relatively large, the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65 is relatively small, and a relatively small magnetic repulsion is used for buffering, so that the columnar foot buckle 51 absorbs external impact energy in the process of slowly contacting the arc-shaped buffer sheet 63, thereby improving the buffering effect and preventing the ship equipment from being damaged due to vibration or impact due to insufficient buffering capacity;

[0050] When the weight of the ship equipment is relatively light, the rotation degree of the rotating rod 721 is small, and the contact area between the first arc-shaped conductive sheet 722 and the second arc-shaped conductive sheet 723 is relatively large. When the weight of the ship equipment is relatively light, the magnetic repulsion force between the first electromagnet 64 and the second electromagnet 65 is relatively large, thereby reducing the buffering effect and preventing the buffering capacity from being too large, which causes the ship equipment to move excessively and generate vibration or unnecessary swing, thereby improving the stability of the ship equipment.

[0051] Specifically, two symmetrically arranged air storage tanks 211 are provided inside the placement plate 21, and the air storage tank 211 is connected to the space below the placement plate 21 in the installation frame 2, and a moving block 212 is airtightly and slidably connected inside the air storage tank 211, and a waterproof membrane 213 is provided at the connection between the air storage tank 211 and the inside of the installation frame 2. The waterproof membrane 213 is made of polyurethane coating material, which can form a waterproof barrier to prevent hydraulic oil from penetrating and has good air permeability. During the installation of the ship equipment, the placement plate 21 is displaced downward relative to the installation frame 2, so that the air inside the installation frame 2 can be first transported to the air storage tank 211, and then The moving block 212 is driven to move in the air storage tank 211 in one step. When the placement plate 21 moves down to contact the hydraulic oil, the placement plate 21 squeezes the hydraulic oil. At this time, the hydraulic oil can be isolated by the water-proof membrane 213 and cannot enter the air storage tank 211, so as to prevent the air in the space below the placement plate 21 in the installation frame 2 from affecting the movement of the placement plate 21 in the installation frame 2, thereby ensuring that the placement plate 21 can automatically pop up after the ship equipment is removed, and unlock the columnar foot buckle 51. At the same time, it will not affect the squeezing of the hydraulic oil by the placement plate 21, so as to prevent the hydraulic oil from flowing into the air storage tank 211, thereby ensuring the detection effect of the ship equipment weight.

[0052] The interior of the fixed platform 1 is also provided with a plurality of groups of compensation mechanisms 8 distributed in a circumferential array, which are used to adjust the distance between the first electromagnet 64 and the second electromagnet 65 after the first electromagnet 64 and the second electromagnet 65 have been working for a long time. The compensation mechanism 8 includes a liquid storage chamber 81 opened inside the fixed platform 1, and the interior of the liquid storage chamber 81 is airtightly and slidably connected with a sealing plate 82. An electric telescopic rod 83 is fixedly connected to the inner wall of one side of the liquid storage chamber 81, and the output end of the electric telescopic rod 83 is fixedly connected to the sealing plate 82. The interior of the fixed platform 1 is provided with a compensation groove 84, and the compensation groove 84 is provided to adjust the distance between the first electromagnet 64 and the second electromagnet 65. A piston push block 85 is airtightly and slidingly connected in the compensation groove 84, a push rod 86 is fixedly connected between the piston push block 85 and the second electromagnet 65, a connecting groove 87 is connected between the liquid storage chamber 81 and the compensation groove 84, the liquid storage chamber 81, the connecting groove 87 and the space on one side of the compensation groove 84 close to the connecting groove 87 are all filled with hydraulic oil, a pressure sensor 88 is provided on the side wall of the arc-shaped buffer sheet 63 close to the columnar foot buckle 51, and the control system arranged inside the fixed platform 1 adjusts the extension length of the electric telescopic rod 83 through the pressure information measured by the pressure sensor 88.

[0053] Specifically, since the control system adopts a PID controller, it can receive the pressure signal output by the pressure sensor 88, calculate the required action according to the preset target pressure value, compare the pressure signal with the expected pressure value, and generate a control instruction to drive the extension or retraction of the electric telescopic rod 83, and maintain the set pressure by adjusting the extension degree of the electric telescopic rod 83.

[0054] Specifically, the electric telescopic rod 83 is composed of an electric motor and a lead screw-guide rail system. The control system disposed inside the fixed platform 1 outputs instructions to drive the electric motor to extend or retract the telescopic rod.

[0055] Taking into account that after the first electromagnet 64 and the second electromagnet 65 have been performing a long-term buffering work on the ship equipment through the magnetic repulsion force, the long-term current supply will cause the iron core or coil material to degrade, resulting in a decrease in the efficiency of the electromagnet, and further resulting in a decrease in the buffering effect of the magnetic repulsion force between the first electromagnet 64 and the second electromagnet 65 on the ship equipment, the present invention sets a compensation mechanism 8. After a long period of use, the staff can turn on the pressure sensor 88 when the hull is relatively stable, and detect the force of the magnetic repulsion force between the first electromagnet 64 and the second electromagnet 65 on the side walls of the columnar foot buckle 51 through the pressure sensor 88. When the pressure sensor 88 detects that the force of the magnetic repulsion force applied to the side walls of the columnar foot buckle 51 is reduced compared to the force when the ship equipment is just being installed, the control system can adjust the extension of the electric telescopic rod 83 according to the pressure information measured by the pressure sensor 88, thereby extending the liquid storage chamber 81. The hydraulic oil is transported to the compensation groove 84 through the connecting groove 87, so that the piston push block 85 in the compensation groove 84 is close to the columnar foot buckle 51, and the second electromagnet 65 is further close to the first electromagnet 64. Because the strength of the magnetic field is inversely proportional to the square of the distance, when the two electromagnets are close to each other, their interaction becomes stronger, so that the magnetic repulsion between the second electromagnet 65 and the first electromagnet 64 can be increased, so that the buffering capacity of the first electromagnet 64 and the second electromagnet 65 can be automatically compensated when the magnetic properties of the first electromagnet 64 and the second electromagnet 65 are degraded. When the force of the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65 applied to the side wall of the columnar foot buckle 51 is the same as that when the ship equipment is just installed, the electric telescopic rod 83 no longer extends, which greatly extends the service life of the first electromagnet 64 and the second electromagnet 65, and ensures the buffering capacity of the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65 for the columnar foot buckle 51.

[0056] The present invention can be explained by the following operation mode:

[0057] During installation, the equipment connection base 3 fixedly connected to the ship equipment is placed on the mounting base 22, and then the clamping frames 43 on both sides are driven by the hydraulic cylinder 42 to clamp on both sides of the equipment connection base 3;

[0058] The ship equipment will make the placement plate 21 move downward relative to the installation frame 2 under the action of its own gravity, and further make the installation frame 2 and the columnar foot buckle 51 at the lower end thereof move downward, and the wedge block 55 on the side wall of the columnar foot buckle 51 can be squeezed into the slide groove 54 by the arc-shaped buffer sheet 63 when its inclined surface contacts the arc-shaped buffer sheet 63, and when the limit ring 53 contacts the upper end of the fixing platform 1, the wedge block 55 is no longer affected by the arc-shaped buffer sheet 63, and automatically pops out from the slide groove 54 under the elastic force of the return spring 58, contacts the lower wall of the fixing platform 1, so that the columnar foot buckle 51 can be embedded and connected to the fixing platform 1, and the installation and fixation of the columnar foot buckle 51 is automatically realized;

[0059] After installation, the arc-shaped buffer sheets 63 are tightly pressed against the peripheral wall of the columnar foot buckle 51 under the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65. When the hull shakes, the columnar foot buckle 51 can overcome the magnetic repulsion between the first electromagnet 64 and the second electromagnet 65 and push the slider 62 to move in the buffer groove 61, thereby avoiding frequent hard collisions between the columnar foot buckle 51 and the mounting hole 52.

[0060] During the installation of the ship equipment, the placement plate 21, the mounting seat 22 and the ship equipment installed thereon will squeeze the hydraulic oil in the mounting frame 2, and the ship equipment of different weights will squeeze the hydraulic oil with different strengths, so that the hydraulic pressure of the hydraulic oil is different. When the weight of the ship equipment changes, the annular hydraulic sensor 71 can transmit different pressure signals to the control system, and further control the rotation degree of the rotating rod 721 through the control system, adjust the contact area between the first arc-shaped conductive sheet 722 and the second arc-shaped conductive sheet 723, thereby realizing the adjustment of the magnetic repulsion force between the first electromagnet 64 and the second electromagnet 65, and can automatically adjust the buffering capacity of the columnar foot buckle 51 and the ship equipment according to the weight of the ship equipment;

[0061] After long-term use, the pressure sensor 88 is turned on to detect the strength of the magnetic repulsion force between the first electromagnet 64 and the second electromagnet 65 applied to the side wall of the columnar foot buckle 51. When the pressure sensor 88 detects that the strength of the magnetic repulsion force applied to the side wall of the columnar foot buckle 51 is reduced compared to when the ship equipment is just installed, the control system can adjust the extension of the electric telescopic rod 83 according to the pressure information measured by the pressure sensor 88, so that the second electromagnet 65 is close to the first electromagnet 64, so that the magnetic repulsion force between the second electromagnet 65 and the first electromagnet 64 is increased, and the buffering capacity is automatically compensated;

[0062] During disassembly and maintenance, the hydraulic cylinder 42 drives the clamping frame 43 to no longer clamp the equipment connecting seat 3, and the ship equipment is removed from the mounting seat 22. The placement plate 21 automatically moves upward in the mounting frame 2 under the elastic force of the reset spring 58, and the wedge block 55 is further pulled into the slide groove 54 by the pull rope 57, so that the wedge block 55 is no longer clamped on the fixed platform 1. At this time, the staff can pull the columnar foot buckle 51 out of the fixed platform 1 by themselves, so as to realize the disassembly-free removal of the columnar foot buckle 51, which is convenient to operate.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
