In addition, people can also use it for various popular digital images, audio and video processing, etc. Smart cameras have pedestrian re-identification functions, using computer vision technology to determine whether there are specific pedestrians in the camera's monitoring image, and can be combined with pedestrian tracking technology to achieve dynamic tracking of specific pedestrian paths, making up for the visual limitations of fixed cameras.

[0003] Among them, the location of the wind power plant in the desert has a high air flow rate and air dryness all year round, which causes the water-soluble grease at the motor output position that controls the camera twisting to dry up, making the camera twisting more difficult. To address the above problems, the following solutions are proposed. Summary of the invention

Before use, the base is installed in the desired position, and the power supply of the electric telescopic rod and the motor is turned on. At this time, the motor drives the camera to rotate through the square telescopic rod to achieve a dynamic tracking effect. When night comes, the temperature in the desert drops. At this time, the electric telescopic rod generates a contraction force, forcing the pressure frame and the sealing The ring moves downward, at this time the sealing ring drives the sliding tube three to move downward synchronously, the sliding tube three slides downward along the inner wall of the sliding tube two, so that the sliding tube two covers the air outlet of the filter screen, so that the bottom of the sliding tube three and the top of the obstruction plate form a closed environment, at this time as the electric telescopic rod contracts, the space of the above-mentioned closed environment gradually shrinks, while the total amount of internal air remains unchanged, so that the internal air is transformed into high-pressure gas, and when the normal air pressure is transformed into high pressure, the overall temperature of the closed environment will increase, and at this time the inside of the equipment is high-pressure and high-temperature gas, and the outside of the equipment is low-temperature gas, under the state of cold outside and hot inside, small water droplets will slowly condense on the inner walls of the sliding tube two, sliding tube one and the base tube, and the small water droplets will slide downward along the inner walls of the above components and mix with the water-soluble grease on the top of the obstruction plate to increase the viscosity of the lubricating fluid inside the equipment. Through the application of the above components, the equipment can be replenished with a small amount of water, thereby extending the service life of the internal grease.

[0007] Preferably, the cleaning component includes a sliding plug ring groove opened on the top of the sliding tube 2, a sliding groove is opened on the inner wall of the sliding plug ring groove, a fixing ring is fixedly connected to the inner wall of the sliding tube 2, and a reset spring is fixedly connected to the bottom of the fixing ring.

[0008] Preferably, the cleaning assembly also includes an annular slide slidably connected to the inner wall of the sliding plug ring groove, the bottom of the annular slide is fixedly connected to an L-shaped arc plate, and one end of the L-shaped arc plate away from the annular slide is fixedly connected to the side wall of the sliding tube three.

[0009] Preferably, the sealing assembly includes a mounting ring fixedly connected to three side walls of the sliding tube, one end of the return spring away from the fixing ring is fixedly connected to the top of the obstruction plate, and a guide assembly is fixedly connected to the side wall of the mounting ring.

[0010] Preferably, the sealing assembly also includes an annular box 1 fixedly connected to the bottom of the mounting ring, a rubber expansion tube is connected through the side wall of the annular box 1, an annular box 2 is fixedly connected to the bottom of the mounting ring, the outer wall of the sealing ring is rotatably connected to the inner wall of the through hole of the pressure frame, and the distance between the sliding tube 2 and the sliding tube 3 will be shortened when the above-mentioned pressure mechanism is in operation, and a cleaning assembly and a sealing assembly are arranged inside the equipment, when the sliding tube 3 is pulled downward by the electric telescopic rod, the sliding tube 3 drives the annular slide plate to slide downward along the inner wall of the sliding plug ring groove through the L-shaped arc plate, and at the same time, the sliding tube 3 drives the annular box 2 and the piston plate to move downward through the mounting ring, and when the bottom of the pressure ring contacts the top of the sliding tube 2, the annular box 1 will enter the inside of the sliding plug ring groove, as the electric telescopic rod contracts, the piston plate will move upward along the inner wall of the annular box 2, and the internal gas of the annular box 2 enters the rubber expansion tube through the annular box 1, forcing the rubber expansion tube to expand inside the sliding plug ring groove, and through the application of the above-mentioned components, the sealing of the above-mentioned enclosed space is improved, and the formation of internal high pressure is avoided, and the phenomenon of pressure relief occurs due to the gap.

[0011] Preferably, the sealing assembly also includes a piston plate slidably connected to the inner wall of the annular box 2, a pressure ring is fixedly connected to the bottom of the piston plate, and the side wall of the annular box 2 is through-connected to the side wall of the annular box 1.

[0012] Preferably, the guide assembly includes a limit plate 1 fixedly connected to the side wall of the mounting ring, a sliding plate slidably connected to the inner wall of the limit plate 1, and an end of the sliding plate away from the limit plate 1 is slidably connected to the limit plate 2, and a circular track is fixedly connected to the side wall of the sliding tube 1. In view of the problem that the wind flow in the desert has a high dust content, a guide assembly is arranged inside the equipment, wherein the sliding tube 3 and the sliding tube 2 are in contact with each other, which ensures that the sliding tube 3 can rotate along the inner wall of the sliding tube 2 and can also slide up and down along the inner wall of the sliding tube 3. The installation direction of the limit plate 1 is consistent with the direction of the filter screen. When the external wind speed is fast, the wind flow will act on the limit plate 1, the sliding plate and the side wall of the limit plate 2, forcing the above components to drive the mounting ring and the sliding tube 3 to rotate with the sealing ring as the center. The position plate 1 rotates due to the wind, forcing the filter to be in a leeward position to prevent the wind from carrying dust directly through the filter and entering the interior of the equipment; in addition, the sliding tube 3, sliding tube 2, sliding tube 1 and base tube are cylindrical. When the external wind flow contacts the outer wall of the above components, the airflow will flow along the outer wall of the above components and form two airflows with unequal pressure differences at both ends of the cylinder. The unequal airflow will swing regularly on the side of the cylindrical component, and the airflow will carry most of the dust and flow synchronously. The swinging area close to the sliding tube 3 is a low flow rate area, and the air dust content in this area is low. Through the application of the above components, the total amount of sand and dust entering the interior of the equipment is greatly reduced when the equipment is ventilated, thereby ensuring the quality of the internal lubricating oil.

[0013] Preferably, the guide assembly also includes a cleaning frame slidably connected to the outer wall of the limit plate one, and one end of the cleaning frame away from the limit plate one is slidably connected to the side wall of the limit plate two, and scrapers are fixedly connected to the two sides of the cleaning frame, and the inner wall of the annular track is slidably connected to the outer wall of the limit plate two. When the pressure-applying mechanism contracts, as the distance between the mounting ring and the sliding tube one is reduced, the mounting ring will drive the limit plate one to move downward, and the limit plate two will be affected by the annular track, and the sliding plate will enter the limit plate two and the inner wall of the limit plate one. At this time, the limit plate one and the limit plate two will scratch and clean the outer wall of the sliding plate. In this process, the cleaning frame will clean the outer wall of the limit plate two and the limit plate one. Through the application of the above-mentioned components, dust residue remaining on the outer walls of the sliding plate, the limit plate one and the limit plate two is effectively removed, so as to avoid excessive dust residue, increase the weight of the guide assembly, and affect the rotation efficiency of the limit plate one, the sliding plate and the limit plate two.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention utilizes the characteristics of large temperature difference between day and night in desert areas and that most lubricating oils are water-soluble greases. A pressure mechanism is provided inside the device. Before use, the base is installed at the desired position and the power of the electric telescopic rod and the motor is turned on. At this time, the motor drives the camera to rotate through the square telescopic rod to achieve a dynamic tracking effect. When night comes, the temperature in the desert drops. At this time, the electric telescopic rod generates a contraction force, forcing the pressure frame and the sealing ring to move downward. At this time, the sealing ring drives the sliding tube three to move downward synchronously. The sliding tube three slides downward along the inner wall of the sliding tube two, so that the sliding tube two covers the air outlet of the filter screen, so that the bottom of the sliding tube three and the top of the obstruction plate form a closed loop. Environment, at this time, as the electric telescopic rod contracts, the space of the above-mentioned closed environment gradually shrinks, while the total amount of air inside remains unchanged, causing the internal air to turn into high-pressure gas. When the normal air pressure turns into high pressure, the overall temperature of the closed environment will increase. At this time, the inside of the equipment is high-pressure and high-temperature gas, and the outside of the equipment is low-temperature gas. Under the state of cold outside and hot inside, small water droplets will slowly condense on the inner walls of the sliding tube 2, sliding tube 1 and base tube, and the small water droplets will slide downward along the inner walls of the above components and mix with the water-soluble grease on the top of the barrier plate to increase the viscosity of the lubricating fluid inside the equipment. Through the application of the above components, the equipment can be supplemented with a small amount of water to extend the service life of the internal grease.

[0016] (2) In order to solve the problem of high dust content in desert wind flow, the present invention provides a guide component inside the device, wherein the sliding tube 3 is arranged in contact with the sliding tube 2, which ensures that the sliding tube 3 can rotate along the inner wall of the sliding tube 2 while also sliding up and down along the inner wall of the sliding tube 3. The installation direction of the limit plate 1 is consistent with the direction of the filter screen. When the external wind speed is fast, the wind flow will act on the limit plate 1, the sliding plate and the side wall of the limit plate 2, forcing the above components to drive the mounting ring and the sliding tube 3 to rotate with the sealing ring as the center. At this time, the limit plate 1 is rotated by the wind, forcing the filter screen to be in a leeward position, thereby preventing the wind flow from carrying dust directly through the filter screen and entering the device. Inside; in addition, the sliding tube three, sliding tube two, sliding tube one and base tube are cylindrical. When the external wind flow contacts the outer wall of the above components, the airflow will flow along the outer wall of the above components and form two airflow differences with unequal pressures at both ends of the cylinder. The unequal airflow will swing regularly on the side of the cylindrical component, and the airflow will carry most of the dust and flow synchronously. The swinging area close to the sliding tube three is a low flow rate area, and the air dust content in this area is low. Through the application of the above components, the total amount of sand and dust entering the equipment is greatly reduced when the equipment is ventilated, thereby ensuring the quality of the internal lubricating oil.

[0017] (3) The present invention utilizes the characteristic that the distance between the sliding tube 2 and the sliding tube 3 will be shortened when the above-mentioned pressure mechanism is in operation. A cleaning component and a sealing component are arranged inside the device. When the sliding tube 3 is pulled downward by the electric telescopic rod, the sliding tube 3 drives the annular slide plate to slide downward along the inner wall of the sliding plug ring groove through the L-shaped arc plate. At the same time, the sliding tube 3 drives the annular box 2 and the piston plate to move downward through the mounting ring. When the bottom of the pressure ring contacts the top of the sliding tube 2, the annular box 1 will enter the interior of the sliding plug ring groove. As the electric telescopic rod contracts, the piston plate will move upward along the inner wall of the annular box 2. The gas inside the annular box 2 enters the rubber expansion tube through the annular box 1, forcing the rubber expansion tube to expand inside the sliding plug ring groove. By using the above-mentioned components, the sealing of the above-mentioned enclosed space is improved, and the formation of internal high pressure is avoided, and the phenomenon of pressure relief due to the gap is avoided.

[0018] (4) When the pressure mechanism of the present invention contracts, as the distance between the mounting ring and the sliding tube 1 is reduced, the mounting ring will drive the limit plate 1 to descend, and the limit plate 2 will be affected by the annular track, and the sliding plate will enter the inner wall of the limit plate 2 and the limit plate 1. At this time, the limit plate 1 and the limit plate 2 will scrape and clean the outer wall of the sliding plate. During this process, the cleaning rack will clean the outer wall of the limit plate 2 and the limit plate 1. Through the application of the above-mentioned components, the dust residue remaining on the outer wall of the sliding plate, the limit plate 1 and the limit plate 2 can be effectively removed to avoid excessive dust residue, increase the load of the guide component, and affect the rotation efficiency of the limit plate 1, the sliding plate and the limit plate 2.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For example, see Figure 1 - Figure 5 The present invention is an intelligent camera with pedestrian re-identification and dynamic tracking, comprising a base 1, a top of the base 1 is fixedly connected to an electric telescopic rod 11, an end of the electric telescopic rod 11 away from the base 1 is fixedly connected to a pressure frame 12, a top of the base 1 is fixedly connected to a fixing frame 13, and a top of the fixing frame 13 is fixedly connected to a mounting plate 14;

[0034] The driving mechanism 2 includes a motor 21 fixedly connected to the inner wall of the mounting plate 14, the output shaft of the motor 21 is fixedly connected to a square telescopic rod 22, one end of the square telescopic rod 22 away from the motor 21 is fixedly connected to a sealing ring 23, and the top of the sealing ring 23 is fixedly connected to a camera 24;

[0035] The pressure-applying mechanism 3 comprises a base tube 31 fixedly connected to the top of the mounting plate 14, a sliding tube 1 32 is slidably connected to the inner wall of the base tube 31, a sliding tube 2 33 is slidably connected to the inner wall of the sliding tube 1 32, a sliding tube 34 is slidably connected to the inner wall of the sliding tube 2 33, a filter screen 35 is fixedly connected to the side wall of the sliding tube 3 34, the inner wall of the through hole at the top of the sliding tube 3 34 is rotatably connected to the outer wall of the sealing ring 23, a cleaning component 4 is fixedly connected to the inner wall of the sliding tube 2 33, and a sealing component 5 is fixedly connected to the side wall of the sliding tube 3 34. Taking advantage of the large temperature difference between day and night in the desert area and the fact that most lubricating oils are water-soluble greases, a pressure-applying mechanism 3 is arranged inside the equipment. Before use, the base 1 is installed in the desired position, and the power supply of the electric telescopic rod 11 and the motor 21 is turned on. At this time, the motor 21 drives the camera 24 to rotate through the square telescopic rod 22 to achieve a dynamic tracking effect. When the time comes to night, the temperature in the desert drops. At this time, the electric telescopic rod 11 generates a contraction force, forcing The pressure frame 12 and the sealing ring 23 move downward, and the sealing ring 23 drives the sliding tube three 34 to move downward synchronously. The sliding tube three 34 slides downward along the inner wall of the sliding tube two 33, so that the sliding tube two 33 covers the air outlet of the filter screen 35, so that the bottom of the sliding tube three 34 and the top of the obstruction plate 36 form a closed environment. At this time, as the electric telescopic rod 11 contracts, the space of the above-mentioned closed environment gradually shrinks, while the total amount of internal air remains unchanged, so that the internal air is transformed into high-pressure gas. When the normal air pressure is transformed into high pressure, the overall temperature of the closed environment will increase. At this time, the inside of the equipment is high-pressure and high-temperature gas, and the outside of the equipment is low-temperature gas. Under the state of cold outside and hot inside, small water droplets will slowly condense on the inner walls of the sliding tube two 33, the sliding tube one 32 and the base tube 31, and the small water droplets will slide downward along the inner walls of the above components and mix with the water-soluble grease on the top of the obstruction plate 36 to increase the viscosity of the lubricating fluid inside the equipment. Through the application of the above components, the equipment can be supplemented with a small amount of water to extend the service life of the internal grease.

[0036] For example 2, please refer to Figure 6 - Fig.10 The present invention is an intelligent camera with pedestrian re-identification and dynamic tracking. On the basis of the first embodiment, the cleaning component 4 includes a sliding plug ring groove 41 opened on the top of the sliding tube 33, a sliding groove 42 is opened on the inner wall of the sliding plug ring groove 41, a fixing ring 43 is fixedly connected to the inner wall of the sliding tube 33, and a reset spring 44 is fixedly connected to the bottom of the fixing ring 43.

[0037] The cleaning assembly 4 also includes an annular slide 46 slidably connected to the inner wall of the sliding plug ring groove 41, and an L-shaped arc plate 45 is fixedly connected to the bottom of the annular slide 46, and one end of the L-shaped arc plate 45 away from the annular slide 46 is fixedly connected to the side wall of the sliding tube three 34.

[0038] The sealing assembly 5 includes a mounting ring 51 fixedly connected to the side wall of the sliding tube 34 , one end of the return spring 44 away from the fixing ring 43 is fixedly connected to the top of the blocking plate 36 , and a guide assembly 6 is fixedly connected to the side wall of the mounting ring 51 .

[0039] The sealing assembly 5 also includes an annular box 1 52 fixedly connected to the bottom of the mounting ring 51, a rubber expansion tube 53 is connected through the side wall of the annular box 1 52, an annular box 2 54 is fixedly connected to the bottom of the mounting ring 51, the outer wall of the sealing ring 23 is rotatably connected to the inner wall of the through hole of the pressure frame 12, and the distance between the sliding tube 2 33 and the sliding tube 3 34 will be shortened when the above-mentioned pressure mechanism 3 is in operation. A cleaning assembly 4 and a sealing assembly 5 are arranged inside the equipment, and when the sliding tube 3 34 is pulled downward by the electric telescopic rod 11, the sliding tube 3 34 drives the annular slide plate 46 to slide downward along the inner wall of the sliding plug ring groove 41 through the L-shaped arc plate 45. At the same time, the sliding tube three 34 drives the annular box two 54 and the piston plate 55 to move downward through the mounting ring 51. When the bottom of the pressure ring 56 contacts the top of the sliding tube two 33, the annular box one 52 will enter the inside of the sliding plug ring groove 41. As the electric telescopic rod 11 contracts, the piston plate 55 will move upward along the inner wall of the annular box two 54. The internal gas of the annular box two 54 enters the rubber expansion tube 53 through the annular box one 52, forcing the rubber expansion tube 53 to expand inside the sliding plug ring groove 41. Through the application of the above components, the sealing of the above enclosed space is improved, and the formation of internal high pressure is avoided, because the gap causes pressure relief.

[0040] The sealing assembly 5 also includes a piston plate 55 slidably connected to the inner wall of the annular box 2 54 , a pressure ring 56 is fixedly connected to the bottom of the piston plate 55 , and the side wall of the annular box 2 54 is through-connected to the side wall of the annular box 1 52 .

[0041] The guide assembly 6 includes a limit plate 61 fixedly connected to the side wall of the mounting ring 51, a sliding plate 62 is slidably connected to the inner wall of the limit plate 61, and one end of the sliding plate 62 away from the limit plate 61 is slidably connected to the limit plate 2 63, and a circular track 64 is fixedly connected to the side wall of the sliding tube 32. In view of the problem that the wind flow in the desert has a high dust content, a guide assembly 6 is arranged inside the equipment, wherein the sliding tube 3 34 and the sliding tube 2 33 are in contact with each other, which ensures that the sliding tube 3 34 can rotate along the inner wall of the sliding tube 2 33 while also sliding up and down along the inner wall of the sliding tube 3 34, and the installation direction of the limit plate 61 is consistent with the direction of the filter screen 35. When the external wind speed is fast, the wind will act on the limit plate 61, the sliding plate 62 and the side wall of the limit plate 2 63, forcing the above components to drive the mounting ring 51 and the sliding tube 3 34 to seal. 23 is the center of the circle and rotates. At this time, the limit plate 61 is rotated by the wind, forcing the filter 35 to be in a leeward position to prevent the wind from carrying dust directly through the filter 35 and entering the interior of the equipment; in addition, the sliding tube 34, the sliding tube 2, the sliding tube 32 and the base tube 31 are cylindrical. When the external wind flow contacts the outer wall of the above components, the air flow will flow along the outer wall of the above components and form two air flow differences with unequal pressures at both ends of the cylinder. The unequal air flow will produce regular swings on the side of the cylindrical component, and the air flow will carry most of the dust and flow synchronously. The swing area close to the sliding tube 34 is a low flow rate area, and the air dust content in this area is low. Through the application of the above components, it is ensured that when the equipment is ventilated, the total amount of sand and dust entering the interior of the equipment is greatly reduced, thereby ensuring the quality of the internal lubricating oil.

[0042] The guide assembly 6 also includes a cleaning frame 65 slidably connected to the outer wall of the limit plate 1 61. The end of the cleaning frame 65 away from the limit plate 1 61 is slidably connected to the side wall of the limit plate 2 63. Scrapers 66 are fixedly connected to both sides of the cleaning frame 65. The inner wall of the annular track 64 is slidably connected to the outer wall of the limit plate 2 63. When the pressure mechanism 3 contracts, as the distance between the mounting ring 51 and the sliding tube 1 32 is reduced, the mounting ring 51 will drive the limit plate 1 61 to descend, and the limit plate 2 63 is affected by the annular track 64, and the sliding plate 62 will enter The inner wall of the limit plate 2 63 and the limit plate 1 61, at this time, the limit plate 1 61 and the limit plate 2 63 will scrape and clean the outer wall of the sliding plate 62. In this process, the cleaning rack 65 will clean the outer wall of the limit plate 2 63 and the limit plate 1 61. Through the application of the above components, the dust residue remaining on the outer wall of the sliding plate 62, the limit plate 1 61 and the limit plate 2 63 can be effectively removed to avoid excessive dust residue, increase the load of the guide component 6, and affect the rotation efficiency of the limit plate 1 61, the sliding plate 62 and the limit plate 2 63.

[0043] A specific application of this embodiment is: before use, the base 1 is installed at the desired position, and the power of the electric telescopic rod 11 and the motor 21 is turned on. At this time, the motor 21 drives the camera 24 to rotate through the square telescopic rod 22 to achieve a dynamic tracking effect. After night time, the temperature in the desert drops. At this time, the electric telescopic rod 11 generates a contraction force, forcing the pressure frame 12 and the sealing ring 23 to move downward. At this time, the sealing ring 23 drives the sliding tube three 34 to move downward synchronously. The sliding tube three 34 slides downward along the inner wall of the sliding tube two 33, so that the sliding tube two 33 covers the air outlet of the filter screen 35, so that the bottom of the sliding tube three 34 and the top of the obstruction plate 36 form a closed environment. At this time, As the electric telescopic rod 11 contracts, the space of the above-mentioned enclosed environment gradually shrinks, while the total amount of air inside remains unchanged, causing the internal air to transform into high-pressure gas. When the normal air pressure transforms into high pressure, the overall temperature of the enclosed environment will increase. At this time, the inside of the equipment is high-pressure and high-temperature gas, and the outside of the equipment is low-temperature gas. Under the condition of cold outside and hot inside, small water droplets will slowly condense on the inner walls of the sliding tube 2 33, the sliding tube 1 32 and the base tube 31, and the small water droplets will slide downward along the inner walls of the above components and mix with the water-soluble grease on the top of the obstruction plate 36, thereby increasing the viscosity of the lubricating fluid inside the equipment. Through the application of the above components, the equipment can be supplemented with a small amount of water, thereby extending the service life of the internal grease.

[0044] In order to solve the problem of high dust content in desert wind flow, a guide assembly 6 is provided inside the device, wherein the sliding tube 3 34 is in contact with the sliding tube 2 33, which ensures that the sliding tube 3 34 can rotate along the inner wall of the sliding tube 2 33 and can also slide up and down along the inner wall of the sliding tube 3 34. The installation direction of the limit plate 1 61 is consistent with the direction of the filter screen 35. When the external wind speed is fast, the wind flow will act on the side walls of the limit plate 1 61, the sliding plate 62 and the limit plate 2 63, forcing the above components to drive the mounting ring 51 and the sliding tube 3 34 to rotate with the sealing ring 23 as the center. At this time, the limit plate 1 61 1 is rotated by the wind, forcing the filter 35 to be in a leeward position, so as to prevent the wind from carrying dust directly into the device through the filter 35; in addition, since the sliding tube 34, the sliding tube 2 33, the sliding tube 1 32 and the base tube 31 are cylindrical, when the external wind flow contacts the outer wall of the above components, the air flow will flow along the outer wall of the above components, and form two air flow differences with unequal pressures at both ends of the cylinder, and the unequal air flow will produce regular swings on the side of the cylindrical component, and the air flow will carry most of the dust and flow synchronously, and the swing area is close to the position of the sliding tube 34 as the low pressure area. The air in this area has a low dust content. By using the above components, the total amount of dust entering the equipment is greatly reduced when the equipment is ventilated, and the quality of the internal lubricating oil is guaranteed. When the pressure mechanism 3 is running, the distance between the sliding tube 2 33 and the sliding tube 3 34 will be shortened. A cleaning component 4 and a sealing component 5 are arranged inside the equipment. When the sliding tube 3 34 is pulled downward by the electric telescopic rod 11, the sliding tube 3 34 drives the annular slide plate 46 to slide downward along the inner wall of the sliding plug ring groove 41 through the L-shaped arc plate 45. At the same time, the sliding tube 3 34 is installed The ring 51 drives the annular box 2 54 and the piston plate 55 to move downward. When the bottom of the pressure ring 56 contacts the top of the sliding tube 2 33, the annular box 1 52 will enter the inside of the sliding plug ring groove 41. As the electric telescopic rod 11 contracts, the piston plate 55 will move upward along the inner wall of the annular box 2 54. The internal gas of the annular box 2 54 enters the rubber expansion tube 53 through the annular box 1 52, forcing the rubber expansion tube 53 to expand inside the sliding plug ring groove 41. Through the application of the above components, the sealing of the above enclosed space is improved, and the formation of internal high pressure is avoided, because the pressure relief phenomenon occurs due to the gap.

[0045] When the pressure mechanism 3 contracts, as the distance between the mounting ring 51 and the sliding tube 32 is reduced, the mounting ring 51 will drive the limit plate 1 61 to descend, and the limit plate 2 63 is affected by the annular track 64, and the sliding plate 62 will enter the inner wall of the limit plate 2 63 and the limit plate 1 61. At this time, the limit plate 1 61 and the limit plate 2 63 will scrape and clean the outer wall of the sliding plate 62. In this process, the cleaning frame 65 will clean the outer wall of the limit plate 2 63 and the limit plate 1 61. Through the application of the above-mentioned components, the dust residue remaining on the outer walls of the sliding plate 62, the limit plate 1 61 and the limit plate 2 63 can be effectively removed to avoid excessive dust residue, increase the load of the guide component 6, and affect the rotation efficiency of the limit plate 1 61, the sliding plate 62 and the limit plate 2 63.
