Description

Technical Field

[0001] The invention relates to the field of suspension wire clamps, and more particularly to a suspension wire clamp hardware for overhead lines. Background Art

[0002] The suspension wire clamp is composed of a bracket U-bolt, a wire clamp hull made of forgeable cast iron, and a pressure plate. It is mainly used to fix the wire on the insulator string or lightning conductor, support and disperse the force of the wire, and ensure the safe operation of the power line;

[0003] When the suspension clamp is used in a large-span transmission line in terrains such as valleys, deep trenches, large rivers, lakes and straits, the suspension clamp is subjected to greater tension due to the large span of the conductor; and the terrains such as valleys, deep trenches, large rivers, lakes and straits will increase the frequency of changes in wind speed and direction. Therefore, under the action of wind, the hull and the hanging plate of the suspension clamp will produce relative movement, and the hanging plate will swing around the hull hanging axis at a small angle, causing grooves to form on the hull hanging axis during the swinging process. As time goes by, these grooves will gradually deepen; when the grooves reach a certain degree, the strength of the hull hanging axis will be greatly reduced, eventually causing the hull to fall from the suspension clamp, causing an accident. Therefore, the suspension clamp needs to be regularly inspected in a comprehensive manner;

[0004] However, the lubrication effect between the hanging shaft and the hanging plate in the existing suspension wire clamp is poor; due to the large pressure between the hanging plate and the hanging shaft, the lubricating oil on the contact surface of the hanging shaft and the hanging plate is in a high-pressure environment, and the high pressure causes the contact part of the hanging shaft and the hanging plate to wear more severely, and produces wear particles, which will be mixed into the lubricating oil to form abrasive pollution, further accelerating the aging and failure of the lubricating oil. When the lubricating oil fails, the wear degree of the hull hanging shaft rapidly deepens in a short period of time, so that the inspection frequency needs to be increased, which increases the workload of the staff. If the suspension wire clamp is already in a deep wear degree before the specified inspection time, it is dangerous.

[0005] Therefore, a suspension wire clamp hardware for overhead lines is proposed. Summary of the invention

[0006] In view of the problems existing in the prior art, the object of the present invention is to provide a suspension wire clamp hardware for overhead lines, which can improve the lubrication effect on the hanging shaft and the hanging plate.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A suspension wire clamp for an overhead line, comprising a hull and a hanging plate, wherein a hanging shaft is arranged on the hull, a plug hole is arranged on the hanging plate, the hanging shaft passes through the plug hole, a U-shaped hanging ring is arranged on the hanging plate, a positive circular ring is arranged on the side wall of the hanging plate, a sealing sleeve is fixedly arranged on the side wall of the positive circular ring away from the hanging plate, a cavity is arranged on the positive circular ring, lubricating oil is filled in the cavity, oil spray pipes are evenly inserted on the side wall of the cavity, and a pressurizing mechanism cooperating with the oil spray pipe is arranged on the positive circular ring;

[0009] A back ring is installed on the side wall of the hanging plate, and the back ring and the positive ring are symmetrically distributed on the side wall on the opposite side of the hanging plate. A sealing sleeve made of elastic material is installed between the side wall of the positive ring, the side wall of the back ring and the hanging plate.

[0010] A transfer cavity is provided on the back ring, a recovery port connected with the transfer cavity is provided on the inner wall of the back ring, a filtering mechanism is provided in the transfer cavity, and a suction mechanism matched with the transfer cavity is provided on the cavity.

[0011] Furthermore, the pressurizing mechanism includes a push rod slidably inserted on the inner side wall of the regular circular ring, and a push plate corresponding to the push rod is provided on the side wall of the hanging shaft, the top wall and the bottom wall of the push plate are both inclined surfaces, and the oil injection pipe and the push plate are staggered.

[0012] Furthermore, an elastic membrane is fixedly mounted on the inner side wall of the cavity, the edge of the elastic membrane is fixedly connected to the side wall of the cavity, and the elastic membrane covers the surface of the push rod.

[0013] During installation, the cable is first installed in the hull, and then the hanging plate is set on the hanging shaft, and the hanging shaft passes through the sealing sleeve, the sealing sleeve is fixedly connected to the side wall of the hanging shaft, and the corresponding side wall of the sealing sleeve is fixedly connected to the side wall of the corresponding positive ring and back ring, so as to achieve a sealing effect and prevent the lubricating oil from flowing out and being lost, and then the hanging plate and the hull are fixed at the designated position through the hanging ring;

[0014] In windy weather, when the hanging shaft is in a straightened state, the push plate on the hanging shaft is not in contact with the push rod. At this time, under the action of the elastic membrane, the push rod extends out of the maximum cavity; when the hanging plate swings around the hull hanging shaft at a small angle, that is, when the hanging plate rotates around the center of the hanging shaft, the push rod gradually contacts the push plate. When the push rod contacts the push plate and the hanging shaft and the hanging plate are still in a relative rotation state, under the action of the inclined surface on the push plate, the push rod retracts into the cavity. At this time, the volume of the cavity is reduced, and under the action of the elastic membrane, the volume of the space containing the lubricating oil in the cavity is further reduced, which plays a role in pressurizing the space containing the lubricating oil in the cavity; at this time, the lubricating oil in the cavity will be squeezed out through the oil injection pipe, which increases the impact force of the lubricating oil. When there is impact When the lubricating oil with force contacts the lubricating oil containing particles in the gap between the hanging shaft and the socket, the lubricating oil containing particles will be washed away and fall into the recovery port on the back ring to be filtered through the filter screen, and then the cavity will suck in the filtered lubricating oil through the absorption mechanism, so as to prepare for work again. Therefore, in the whole process, the lubrication effect on the contact part between the hanging plate and the hanging shaft is improved, and the wear degree of the hanging plate is reduced, so that there is no need for frequent inspection by the staff, which plays a role in reducing the workload of the staff; at the same time, by setting a sealing sleeve made of elastic material, part of the kinetic energy of the hanging shaft and the hanging plate can be absorbed, which plays a role in ensuring that the hanging shaft and the hanging plate can be reset, and under the action of the elastic membrane, it can ensure that the cavity is pressurized when the push rod is worn.

[0015] Furthermore, the suction mechanism includes a catheter inserted on the side wall of the transfer chamber and extending into the cavity, and a one-way valve whose output end is connected to the cavity is embedded in the catheter;

[0016] The output end of the fuel injection pipe is funnel-shaped, an elastic rope is fixedly installed on the inner wall of the fuel injection pipe, and a blocking block matched with the fuel injection pipe is installed on the elastic rope.

[0017] When the push rod is extended from the cavity to the maximum, the side wall of the sealing block fits against the side wall of the fuel injection pipe under the action of the elastic rope, and the fuel injection pipe is blocked at this time; when the push rod is retracted into the cavity to the maximum, the space filled with lubricating oil in the cavity is pressurized, and with the cooperation of the one-way valve, the lubricating oil in the cavity exerts pressure on the sealing block. At this time, the sealing block is out of contact with the side wall of the fuel injection pipe, and the elastic rope is in a stretched state. The sealing block is shaken by the impact of the lubricating oil, and the flow direction of the lubricating oil discharged from the fuel injection pipe is changed, thereby increasing the probability of contact between the clean lubricating oil with impact force and the lubricating oil containing particles in the socket, thereby improving the transfer effect of the lubricating oil containing particles.

[0018] When the push rod is extended from the cavity again, the elastic membrane recovers. At this time, the space filled with lubricating oil in the cavity is in a negative pressure state. Therefore, the filtered lubricating oil can be absorbed from the transfer cavity through the catheter, thus preparing for work again.

[0019] Furthermore, a guide channel is provided on the push rod, one end of which is connected to the cavity, and air holes are evenly provided on the side wall of the guide channel, and the air holes are used to blow air to the surface of the hanging shaft and the hanging ring.

[0020] When the push plate is no longer squeezed, the elastic membrane recovers. At this time, the air between the elastic membrane and the side wall of the cavity is discharged through the guide channel, thereby driving the air flow at the contact point between the hanging shaft and the hanging plate, transferring the heat generated by friction in time, allowing the metal to maintain its hardness and strength, and playing a role in reducing the wear rate.

[0021] Furthermore, the filtering mechanism comprises a diaphragm made of elastic material installed in the transfer cavity, the diaphragm is located between the conduit and the recovery port, and a filter screen is embedded on the diaphragm.

[0022] During the operation of overhead power transmission lines, due to the effect of wind, the transmission lines will generate breeze vibrations. At this time, the vibrations are transmitted to the suspension wire clamp, which can drive the filter to shake. During the shaking of the filter, the lubricating oil is driven to shake. The lubricating oil and particulate matter will be affected by inertial force. Due to the different densities of the particulate matter and the lubricating oil, the inertial forces they are subjected to will also be different. This difference will cause the particulate matter to move relative to the lubricating oil, which may cause the particulate matter to gather on one side of the container, speeding up the precipitation of the particulate matter in the lubricating oil, and the shaking can shake off the particulate matter stuck in the filter, which ensures that the lubricating oil can pass through the filter.

[0023] Furthermore, the blocking block includes a ball head and a rotating shaft, the ball head is provided with a mounting hole, the rotating shaft is rotatably inserted in the mounting hole, and the elastic rope is installed at the end of the rotating shaft, the blocking block is sleeved with an elastic sleeve, and the elastic sleeve is provided with a guide groove that is evenly inclined.

[0024] Since the lubricating oil contains particles smaller than the filter holes and the lubricating oil is attached to the inner wall of the fuel injection pipe, the elastic sleeve can be provided to improve the sealing effect of the sealing block on the fuel injection pipe, thereby ensuring that the cavity can absorb a sufficient amount of lubricating oil when the cavity absorbs oil from the transfer cavity.

[0025] The lubricating oil discharged from the oil injection pipe impacts the side wall of the guide groove. At this time, the impact force can drive the ball head to rotate around the rotating shaft. Heat is generated due to friction during the rotation process. The heat is transferred to the lubricating oil in contact with the elastic sleeve, thereby enhancing the fluidity of the lubricating oil. The lubricating oil can then flow evenly to the contact area between the hanging shaft and the hanging plate, thereby improving the lubrication effect.

[0026] Furthermore, the elastic rope is a hollow structure, the blocking block is formed by kneading metal wire, the rotating shaft is evenly provided with through holes that are interconnected, and the inner wall of the elastic rope is provided with small holes, which are used to blow air into the through holes.

[0027] When the blocking block swings, the elastic rope is stretched or restored, so the elastic rope with a hollow structure will exhaust air outward through the small hole. The blocking block formed by kneading the metal wire has a hollow structure. With the cooperation of the through hole, the heat generated by the friction between the blocking block and the rotating shaft can be transferred to the surface of the elastic sleeve in time, thereby improving the heating effect of the lubricating oil in contact with the elastic sleeve. At the same time, the friction between the hollow blocking block and the rotating shaft is relatively large, which plays a role in improving the heat generation effect.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) This scheme provides a cavity, a pressurizing mechanism, and lubricating oil, and can pressurize the lubricating oil discharged from the oil injection pipe through the pressurizing mechanism, thereby increasing the impact force of the lubricating oil. When the lubricating oil with impact force contacts the lubricating oil containing particles in the gap between the hanging shaft and the socket, the lubricating oil containing particles will be washed away, thereby improving the lubrication effect on the contact part between the hanging plate and the hanging shaft, reducing the wear of the hanging plate, and eliminating the need for frequent inspection by staff, thereby reducing the workload of staff;

[0030] (2) This scheme can block the oil injection pipe by setting an elastic rope and a blocking block, thereby ensuring that the cavity can absorb the lubricating oil in the transfer chamber. In addition, during the oil injection process of the oil injection pipe, the blocking block will shake. Under the guidance of the outer wall of the blocking block, the flow range of the lubricating oil sprayed from the oil injection pipe is expanded, thereby expanding the contact probability between the clean lubricating oil and the lubricating oil containing particles, and improving the transfer effect of the lubricating oil containing particles.

[0031] (3) This scheme can filter and recover the cleaned lubricating oil by setting a back ring, a filter screen and a duct, thereby realizing the recycling of the lubricating oil and playing a role in ensuring the lubrication effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiment 1:

[0045] See also Figures 1 to 9 A suspension wire clamp for an overhead line, comprising a hull 1 and a hanging plate 3, wherein a hanging shaft 2 is arranged on the hull 1, a plug hole is provided on the hanging plate 3, the hanging shaft 2 passes through the plug hole, a U-shaped hanging ring 4 is provided on the hanging plate 3, a positive circular ring 5 is installed on the side wall of the hanging plate 3, a sealing sleeve 8 is fixedly installed on the side wall of the positive circular ring 5 away from the hanging plate 3, a cavity 6 is opened on the positive circular ring 5, lubricating oil is filled in the cavity 6, an oil injection pipe 22 is evenly inserted on the side wall of the cavity 6, and a pressurizing mechanism cooperating with the oil injection pipe 22 is provided on the positive circular ring 5;

[0046] A back ring 7 is installed on the side wall of the hanging plate 3. The back ring 7 and the positive ring 5 are symmetrically distributed on the side wall of the hanging plate 3 on the opposite side. A sealing sleeve 8 made of elastic material is installed between the side wall of the positive ring 5, the side wall of the back ring 7 and the hanging plate 3.

[0047] A transfer chamber 9 is provided on the back ring 7 , a recovery port 10 communicating with the transfer chamber 9 is provided on the inner wall of the back ring 7 , a filtering mechanism is provided in the transfer chamber 9 , and a suction mechanism cooperating with the transfer chamber 9 is provided on the cavity 6 .

[0048] The pressurizing mechanism includes a push rod 11 slidably inserted on the inner wall of the regular circular ring 5, and a push plate 12 corresponding to the push rod 11 is provided on the side wall of the hanging shaft 2. The top wall and the bottom wall of the push plate 12 are both inclined surfaces, and the oil injection pipe 22 is staggered with the push plate 12.

[0049] An elastic membrane 13 is fixedly mounted on the inner side wall of the cavity 6 , the edge of the elastic membrane 13 is fixedly connected to the side wall of the cavity 6 , and the elastic membrane 13 covers the surface of the push rod 11 .

[0050] During installation, the cable is first installed in the hull 1, and then the hanging plate 3 is sleeved on the hanging shaft 2, and the hanging shaft 2 passes through the sealing sleeve 8, the sealing sleeve 8 is fixedly connected to the side wall of the hanging shaft 2, and the corresponding side wall of the sealing sleeve 8 is fixedly connected to the side wall of the corresponding positive ring 5 and the back ring 7, so as to achieve a sealing effect and prevent the lubricating oil from flowing out and being lost, and then the hanging plate 3 and the hull 1 are fixed at a designated position through the hanging ring 4;

[0051] In windy weather, when the hanging shaft 2 is in the straightened state, the push plate 12 on the hanging shaft 2 is not in contact with the push rod 11. At this time, under the action of the elastic membrane 13, the push rod 11 extends out of the maximum cavity 6; when the hanging plate 3 swings around the hanging shaft 2 of the hull 1 at a small angle, that is, when the hanging plate 3 rotates around the center of the hanging shaft 2, the push rod 11 gradually contacts the push plate 12. When the push rod 11 contacts the push plate 12 and the hanging shaft 2 and the hanging plate 3 are still in a relative rotation state, under the action of the inclined surface on the push plate 12, the push rod 11 retracts into the cavity 6. At this time, the volume of the cavity 6 is reduced, and under the action of the elastic membrane 13, the volume of the space containing the lubricating oil in the cavity 6 is further reduced, which plays a role in pressurizing the space containing the lubricating oil in the cavity 6; at this time, the lubricating oil in the cavity 6 will be squeezed out through the oil injection pipe 22, increasing the lubricating oil The impact force of the impact, when the lubricating oil with impact force contacts the lubricating oil containing particles in the gap between the hanging shaft 2 and the socket, the lubricating oil containing particles will be washed away and fall into the recovery port 10 on the back ring 7 to be filtered through the filter screen 21, and then the cavity 6 will suck in the filtered lubricating oil through the absorption mechanism, so as to be ready for work again. Therefore, in the whole process, the lubrication effect on the contact part between the hanging plate 3 and the hanging shaft 2 is improved, and the wear degree of the hanging plate 3 is reduced, so that the staff does not need to check frequently, which plays a role in reducing the workload of the staff; at the same time, by setting the sealing sleeve 8 of elastic material, part of the kinetic energy of the hanging shaft 2 and the hanging plate 3 can be absorbed, so as to ensure that the hanging shaft 2 and the hanging plate 3 can be reset, and under the action of the elastic membrane 13, it can ensure that the cavity 6 is pressurized when the push rod 11 is worn.

[0052] like Figure 7 , Figure 8 As shown, by adopting the above technical solution, the suction mechanism includes a conduit 14 inserted on the side wall of the transfer chamber 9 and extending into the cavity 6, and a one-way valve 15 whose output end is connected to the cavity 6 is embedded in the conduit 14;

[0053] The output end of the fuel injection pipe 22 is in a funnel state, and its diameter increases with the increase of the distance from the cavity 6. An elastic rope 16 is fixedly installed on the inner wall of the fuel injection pipe 22, and a blocking block 17 that cooperates with the fuel injection pipe 22 is installed on the elastic rope 16.

[0054] When the push rod 11 is extended out of the cavity 6 to the maximum extent, under the action of the elastic rope 16, the side wall of the blocking block 17 fits against the side wall of the fuel injection pipe 22, and the fuel injection pipe 22 is blocked at this time; when the push rod 11 is retracted into the cavity 6 to the maximum extent, the space filled with lubricating oil in the cavity 6 is pressurized, and with the cooperation of the one-way valve 15, the lubricating oil in the cavity 6 exerts pressure on the blocking block 17, and at this time the blocking block 17 is out of contact with the side wall of the fuel injection pipe 22, and the elastic rope 16 is in a stretched state, and the blocking block 17 impacted by the lubricating oil shakes, and at this time the flow direction of the lubricating oil discharged from the fuel injection pipe 22 is changed, thereby increasing the probability of contact between the clean lubricating oil with impact force and the lubricating oil containing particles in the jack, and improving the transfer effect of the lubricating oil containing particles.

[0055] When the push rod 11 is extended from the cavity 6 again, the elastic membrane 13 is restored. At this time, the space filled with lubricating oil in the cavity 6 is in a negative pressure state. Therefore, the filtered lubricating oil can be absorbed from the transfer cavity 9 through the conduit 14, which plays a role in preparing for work again.

[0056] like Figure 6 As shown, by adopting the above technical solution, a guide channel 18 is opened on the push rod 11, one end of the guide channel 18 is connected to the cavity 6, and air holes 19 are evenly opened on the side wall of the guide channel 18, and the air holes 19 are used to blow air to the surface of the hanging shaft 2 and the hanging ring 4.

[0057] When the push plate 12 is no longer squeezed, the elastic membrane 13 recovers, and the air between the elastic membrane 13 and the side wall of the cavity 6 is discharged through the guide channel 18, thereby driving the air flow at the contact point between the hanging shaft 2 and the hanging plate 3, and transferring the heat generated by friction in time, so that the metal can maintain its hardness and strength, thereby reducing the wear rate.

[0058] like Figure 8 As shown, by adopting the above technical solution, the filtering mechanism includes a diaphragm 20 made of elastic material installed in the transfer chamber 9, the diaphragm 20 is located between the conduit 14 and the recovery port 10, and a filter screen 21 is embedded in the diaphragm 20.

[0059] During the operation of the overhead transmission line, due to the effect of wind force, the transmission line will generate breeze vibration, and the vibration is transmitted to the suspension wire clamp, thereby driving the filter 21 to shake, and driving the lubricating oil to shake during the shaking of the filter 21. The lubricating oil and particulate matter will be affected by inertial force. Due to the different densities of the particulate matter and the lubricating oil, the inertial force they are subjected to will also be different. This difference will cause the particulate matter to move relative to the lubricating oil, which may cause the particulate matter to gather on one side of the container, accelerate the sedimentation rate of the particulate matter in the lubricating oil, and the shaking can shake off the particulate matter stuck in the filter 21, which plays a role in ensuring that the lubricating oil can pass through the filter 21.

[0060] like Figure 7 As shown, by adopting the above technical solution, the blocking block 17 includes a ball head 1701 and a rotating shaft 1702, the ball head 1701 is provided with a mounting hole, the rotating shaft 1702 is rotatably inserted in the mounting hole, and the elastic rope 16 is installed at the end of the rotating shaft 1702, the blocking block 17 is provided with an elastic sleeve 23, and the elastic sleeve 23 is provided with a guide groove 24 that is uniformly inclined.

[0061] Since the lubricating oil contains particles whose volume is smaller than the holes of the filter 21, and the lubricating oil is attached to the inner wall of the fuel injection pipe 22, the elastic sleeve 23 is provided to improve the sealing effect of the sealing block 17 on the fuel injection pipe 22, thereby ensuring that the cavity 6 can absorb a sufficient amount of lubricating oil when the cavity 6 absorbs oil from the transfer cavity 9.

[0062] The lubricating oil discharged from the oil injection pipe 22 impacts the side wall of the guide groove 24. At this time, the ball head 1701 can be driven to rotate around the rotating shaft 1702 under the action of the impact force. Heat is generated due to friction during the rotation process. The heat is transferred to the lubricating oil in contact with the elastic sleeve 23, thereby enhancing the fluidity of the lubricating oil, so that the lubricating oil can flow evenly to the contact part between the hanging shaft 2 and the hanging plate 3, thereby improving the lubrication effect.

[0063] like Figure 7 As shown, by adopting the above technical solution, the elastic rope 16 is a hollow structure, the blocking block 17 is formed by kneading metal wire, the rotating shaft 1702 is evenly provided with interconnected through holes 25, and the inner wall of the elastic rope 16 is provided with small holes, which are used to blow air into the through holes 25.

[0064] When the blocking block 17 swings, the elastic rope 16 is stretched or restored, so the elastic rope 16 with a hollow structure will exhaust air outward through the small hole. The blocking block 17 formed by kneading the metal wire has a hollow structure. With the cooperation of the through hole 25, the heat generated by the friction between the blocking block 17 and the rotating shaft 1702 can be transferred to the surface of the elastic sleeve 23 in time, thereby improving the heating effect of the lubricating oil in contact with the elastic sleeve 23. At the same time, the friction between the hollow blocking block 17 and the rotating shaft 1702 is relatively large, which plays a role in improving the heat generation effect.

[0065] Usage: During installation, first install the cable in the hull 1, then sleeve the hanging plate 3 on the hanging shaft 2, and the hanging shaft 2 passes through the sealing sleeve 8, the sealing sleeve 8 is fixedly connected to the side wall of the hanging shaft 2, and the corresponding side wall of the sealing sleeve 8 is fixedly connected to the side wall of the corresponding positive ring 5 and the back ring 7, so as to achieve a sealing effect and prevent the lubricating oil from flowing out and being lost, and then fix the hanging plate 3 and the hull 1 at the designated position through the hanging ring 4;

[0066] In windy weather, when the hanging shaft 2 is in the straightened state, the push plate 12 on the hanging shaft 2 is not in contact with the push rod 11. At this time, under the action of the elastic membrane 13, the push rod 11 extends out of the maximum cavity 6; when the hanging plate 3 swings around the hanging shaft 2 of the hull 1 at a small angle, that is, when the hanging plate 3 rotates around the center of the hanging shaft 2, the push rod 11 gradually contacts the push plate 12. When the push rod 11 contacts the push plate 12 and the hanging shaft 2 and the hanging plate 3 are still in a relative rotation state, under the action of the inclined surface on the push plate 12, the push rod 11 retracts into the cavity 6. At this time, the volume of the cavity 6 is reduced, and under the action of the elastic membrane 13, the volume of the space containing the lubricating oil in the cavity 6 is further reduced, which plays a role in the cavity 6. The space filled with lubricating oil is pressurized; at this time, the lubricating oil in the cavity 6 will be squeezed out through the oil injection pipe 22, which increases the impact force of the lubricating oil. When the lubricating oil with impact force contacts the lubricating oil containing particles in the gap between the hanging shaft 2 and the socket, the lubricating oil containing particles will be washed away and fall into the recovery port 10 on the back ring 7 to be filtered through the filter screen 21, and then the cavity 6 will suck in the filtered lubricating oil through the absorption mechanism, so that it can be prepared for work again. Therefore, in the whole process, the lubrication effect on the contact part between the hanging plate 3 and the hanging shaft 2 is improved, and the wear degree of the hanging plate 3 is reduced, so there is no need for frequent inspections by staff, which plays a role in reducing the workload of staff.

[0067] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
