Description

Technical Field

[0001] This invention relates to the field of landslide early warning equipment technology, specifically a high-precision landslide emergency early warning device. Background Technology

[0002] A landslide emergency early warning device is used to monitor landslide disasters and can provide real-time landslide early warning information. This device generally consists of various sensors, a data acquisition system, a data processing module, and a communication module. Existing devices for detecting landslide disasters include inclinometers, weather stations, soil moisture meters, and seismometers. Among these, soil moisture meters can monitor the soil moisture content within the landslide body in real time and provide information on soil moisture differences between various monitoring points, providing a relatively accurate prediction of landslide occurrences. The moisture detection data is then transmitted to the landslide emergency early warning device. If the moisture detection data reaches a preset value at the terminal, the landslide emergency early warning device will issue an alarm to alert the surrounding area and transmit the warning information to the terminal so that appropriate measures can be taken in a timely manner to avoid devastating losses. This is of great significance for protecting people's lives and property and reducing losses from natural disasters.

[0003] The existing Chinese patent application number is 2020108512451, entitled "Soil Moisture Detection Device," which includes a tube body with a fixing device at the lower end. A detection device is installed inside the tube body, a display device is mounted on the tube body, and a liquid absorption device is located within the tube body. This technical solution aims to address the problem that the moisture content of soil at different locations may vary, making it difficult to obtain accurate location moisture content. The solution uses a servo motor to control the rotation of a shaft, thereby changing the detection direction of the moisture detection head. Using a single probe allows for multi-directional moisture content detection, effectively increasing the device's accuracy. However, during detection, moist soil will enter through the square holes in each group and accumulate inside the tube body. Because the tube body is a closed structure and the liquid absorption device... The device absorbs moisture through a sponge. However, when the surface area of ​​the sponge changes or the ambient temperature and humidity change, the moisture on the sponge can still evaporate inside the tube, causing external soil to enter the tube. This leads to the evaporation of water vapor from the soil inside the tube, resulting in reduced detection accuracy. Secondly, when changing the orientation of the moisture detection head, because the mounting groove is horizontal, the moisture and soil inside the mounting groove may expand and contract synchronously during the expansion and contraction of the moisture detection head. When the moisture detection head changes orientation, the original moisture and soil in the mounting groove will affect the detection effect, reducing its accuracy. The emergency warning device of this invention is used in special environments, such as environments where earthquakes or humidity are frequent. Therefore, a high-precision landslide emergency warning device is needed to avoid the risk of landslides. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By applying the technical solution of the present invention, the present invention addresses the problems encountered in the existing high-precision landslide emergency early warning device. The present invention can clean the soil during the retraction of the moisture detection head by the first and second desliming components, and does not require electric drive.

[0017] 2. Applying the technical solution of this invention, addressing the problems encountered in high-precision landslide emergency early warning devices in the prior art, this invention automatically seals the through hole through a switching component during the repositioning process of the moisture detection head. Moreover, with the cooperation of the sealing components, it can seal the hole in time at the repositioning position. This invention also sets up a second mud removal component to extend the outer ring from the detector and the outer ring. During the extension process, most of the soil is cleaned from the detector and the inclined sleeve, preventing soil from adhering between the detector and the inclined sleeve and entering the tube body. Therefore, this invention can simultaneously clean the outer surface of the moisture detection head and the inclined sleeve, as well as the soil between the detector and the inclined sleeve, preventing the detector from detecting the moisture of the original soil when changing to different positions, which would reduce the detection accuracy.

[0018] 3. The present invention also improves the sealing performance of the pipe body through the cooperation of the first sealing plate and the second sealing plate, as well as the first sealing plate and the sealing ring. Furthermore, the sealing effect is further improved through the cooperation of the release spring telescopic rod and the first compression spring. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1 to 14 The present invention provides a technical solution:

[0045] Example 1: As Figures 1-5As shown, a high-precision landslide emergency early warning device includes a pipe body 1, a mounting plate 2 installed on top of the pipe body 1, and a controller 3 installed on top of the mounting plate 2 via a top rod. An alarm is installed on the controller 3. A drive motor 4 is installed at the top of the inner cavity of the pipe body 1. The drive motor 4 is rotatably connected to a rotating cylinder 41 via a coupling. The bottom of the rotating cylinder 41 is installed on the bottom wall of the inner cavity of the pipe body 1 via a rotating shaft. A series of through holes 43 arranged in a ring are opened on the outer side of the pipe body 1. Multiple moisture detection heads 42 are provided at the outer front end of the rotating cylinder 41, sliding through one of the through holes 43. The pipe body 1 is positioned at each group of moisture detection heads 42. A screw conveyor plate 11 is installed on the top of the 2. Multiple moisture detection heads 42 are installed along the outer side of the central axis of the pipe body 1. The multiple moisture detection heads 42 are arranged in a linear array. A telescopic component 5 is provided between the rotating drum 41 and the multiple moisture detection heads 42. A switch component 6 is provided in each group of through holes 43 near the central axis of the pipe body 1. A first desludge component 7 is provided in each group of through holes 43 near the central axis of the pipe body 1 and outside the switch component 6. A second desludge component 8 is provided in each group of through holes 43 away from the central axis of the pipe body 1. A sealing component 9 is provided on the rotating drum 41 to seal the through holes 43.

[0046] During operation, the device is first placed in a soil trough on the landslide. The soil and mounting plate 2 are then aligned and fixed to the soil with bolts. When detecting soil moisture at different locations, the drive motor 4 is started, and the rotating drum 41 rotates on the tube 1 until the moisture detection head 42 is aligned with one of the through holes 43. Then, the telescopic component 5 extends the moisture detection head 42 through the through hole 43 and makes contact with the soil through the detector. The data detected by the detector is transmitted to the controller 3. When the detected data exceeds the preset value, an alarm is triggered to alert people in the vicinity, and the data is transmitted wirelessly to the terminal so that staff can analyze the surrounding landslide and take effective control measures for the landslide later.

[0047] While the moisture detection head 42 is detecting within a set of through holes 43, the remaining through holes 43 are sealed by the sealing component 9. Furthermore, during the rotation of the rotating drum 41, the switching component 6 inside the through holes 43 effectively controls the entry of external soil into the tube body 1, improving the sealing performance of the tube body 1. When the moisture detection head 42 retracts from the tube body 1, the first desliming component 7 and the second desliming component 8 work together to automatically clean the soil from the outer wall of the moisture detection head 42 and the detector, preventing soil from entering the tube body 1 and causing the soil moisture inside the tube body 1 to evaporate, thus affecting the detector's detection effect. Simultaneously, this prevents the detector from carrying original soil when changing positions, thus avoiding inaccurate detection data.

[0048] It is worth noting that the present invention is provided with a screw conveyor plate 11, which helps to protect the detector from being squeezed by hard soil, thus preventing damage to the detector. At the same time, it helps to increase the contact area between the screw conveyor plate 11 and the soil, thereby improving the stability of the device.

[0049] Example 2:

[0050] The technical solution is basically the same as that in Embodiment 1, except that... Figures 2-4 As shown, the telescopic assembly 5 includes an electric actuator 51 disposed at the middle of the front end of the rotating drum 41. A storage groove is provided at the middle of the front end of the rotating drum 41, and the electric actuator 51 is installed in the storage groove. A first arc-shaped connecting plate 52 is installed at the moving end of the electric actuator 51. The first arc-shaped connecting plate 52 is installed between each set of moisture detection heads 42. A spring groove is provided on one side of the front end of the rotating drum 41 corresponding to each set of moisture detection heads 42. The rear end of the moisture detection head 42 slides through the rotating drum 41 and a limiting plate 53 is installed in the spring groove. An expansion spring 54 is installed in the spring groove at the rear end of the limiting plate 53.

[0051] During operation, when it is necessary to extend or retract the moisture detection head 42, the electric actuator 51 is driven, and then the first arc-shaped connecting plate 52 is driven to extend or retract a set of moisture detection heads 42 along the through hole 43. Then the electric actuator 51 is closed, and the moisture detection head 42 is supported by the expansion spring 54, reducing the waste of resources on the electric actuator 51. Moreover, when the moisture detection head 42 is inside the tube body 1, the expansion spring 54 and the limiting plate 53 drive the moisture detection head 42 to be squeezed against the inner wall of the tube body 1, without the need for the electric actuator 51. The electric actuator 51 is set in this invention to drive the moisture detection head 42 to extend or retract slowly on the through hole 43, preventing the detector from being quickly pushed out of the through hole 43 by the expansion spring 54 and colliding with the soil.

[0052] Example 3:

[0053] The technical solution is basically the same as that in Embodiment 1, except that... Figures 5-7As shown, the switch assembly 6 includes a horizontal plate 61. A square groove 60 is formed at the top of each set of through holes 43 on the tube body 1. The horizontal plate 61 is fixedly connected to the side wall of the square groove 60 near the central axis of the rotating cylinder 41. A rotating shaft 62 is rotatably connected to the other side of the horizontal plate 61 away from the central axis of the rotating cylinder 41. A cover plate 63 covering the through holes 43 is installed at the bottom of the rotating shaft 62. Notably, one set of cover plates 63 is inside the square groove 60 and tightly attached to the moisture detection head 42. Vertical plates 64 are installed at both ends of the rotating shaft 62. A rotating plate 65 is rotatably connected to the top of the vertical plate 64. A first compression spring 67 is installed on the outer side of the rotating plate 65 away from the central axis of the rotating cylinder 41. A fixing plate 66 is installed on the side of the first compression spring 67 away from the rotating plate 65. The fixing plate 66 is fixedly connected to the top wall of the square groove 60. A first sealing plate 611 is installed on the side of the cover plate 63 near the central axis of the rotating cylinder 41. A second sealing plate 612 is sleeved in the through hole 43 near the central axis of the rotating cylinder 41, and the first sealing plate 611 slides through the interior of the second sealing plate 612.

[0054] During operation, as the moisture detection head 42 extends from the through hole 43, its cover plate 63 rotates along the rotating shaft 62 and retracts within the square groove 60. Then, the rotating plate 65 rotates on the vertical plate 64, causing the first compression spring 67 to expand. When the moisture detection head 42 retracts, the elastic potential energy of the first compression spring 67 is released, causing the rotating plate 65 and the vertical plate 64 to return to their original positions. This causes the cover plate 63 to automatically reset, preventing external soil from entering the through hole 43 and effectively hindering soil entry.

[0055] It is worth noting that the present invention sets the rotating plate 65 to rotate on the expansion spring 54, which helps to prevent the first compression spring 67 from being subjected to torque force during the rotation of the cover plate 63.

[0056] It is worth noting that the second sealing plate 612 in this invention helps prevent external liquid from entering the interior of the rotating cylinder 41 through the moisture detection head 42 when it extends out of the outside of the rotating cylinder 41. At the same time, with the cooperation of the first sealing plate 611, the elastic potential energy of the first compression spring 67 is released, making the first sealing plate 611 and the second sealing plate 612 fit more tightly, effectively preventing external moisture from entering and improving the sealing performance of this invention.

[0057] Example 4:

[0058] The technical solution is basically the same as that in Embodiment 1, except that... Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, the first sludge removal assembly 7 includes multiple reset springs 71. The bottom wall of the through hole 43 is provided with an inclined auxiliary groove. The multiple reset springs 71 are installed on the bottom wall of the auxiliary groove. The top of the reset springs 71 slides through the inside of the through hole 43 and is fitted with a T-shaped plate 72. An elastic waterproof material 73 is installed between the T-shaped plate 72 and the top wall of the through hole 43. An elastic rope 74 in a ring array is installed in the inner cavity of the elastic waterproof material 73. Circular elastic material 75 for squeezing the outside of the moisture detection head 42 is installed on the opposite sides of the multiple elastic ropes 74. An inclined sleeve 44 adapted to the T-shaped plate 72 is installed on the outside of the moisture detection head 42 along the central axis of the rotating drum 41. The inclined sleeve 44 is located on the outside of the detector.

[0059] During operation, as the inclined sleeve 44 on the moisture detection head 42 moves within the through hole 43, it first contacts the T-shaped plate 72 and drives the T-shaped plate 72 to retract into the auxiliary groove under pressure. During the retraction of the T-shaped plate 72, the elastic waterproof material 73 is driven to unfold in the through hole 43 until the moisture detection head 42 passes through the middle of the elastic waterproof material 73. At this time, the cooperation of the elastic rope 74 and the circular elastic material 75 helps to prevent external impurities and moisture from entering the tube body 1. Moreover, during the retraction of the moisture detection head 42, it is convenient to clean the excess soil on the moisture detection head 42.

[0060] It is worth noting that the present invention is provided with an inclined sleeve 44, which is beneficial to drive the T-shaped plate 72 to retract through the mutual cooperation of the T-shaped plate 72 without the need for electric drive. The kinetic energy of the movement of the moisture detection head 42 is transferred to the first desludge assembly 7, thereby enabling the first desludge assembly 7 to achieve the purpose of cleaning the soil and improving the degree of automation of the present invention.

[0061] Example 5:

[0062] The technical solution is basically the same as that in Embodiment 1, except that... Figure 5 , Figure 6 , Figure 8 and Figure 10As shown, the second sludge removal assembly 8 includes a second compression spring 81. A horizontally arranged linkage groove 80 is provided at the bottom of the through hole 43 in the pipe body 1. The second compression spring 81 is installed inside the linkage groove 80. A baffle 82 is installed on the outer side of the second compression spring 81 along the central axis of the rotating drum 41. One end of the baffle 82 slides through the outer side of the pipe body 1 and is fitted with an L-shaped plate 83. A sleeve 84 is installed on the horizontal end of the L-shaped plate 83. The sleeve 84 is adapted to the other sleeve. An outer ring 85 for squeezing the outer wall of the detector is provided in the middle of the sleeve 84. The inner cavity of the horizontal end of the L-shaped plate 83 is provided with a drive assembly for driving the outer ring 85 to rotate. The drive assembly includes multiple gear teeth 811 arranged in a ring array on the outer wall of the outer ring 85. The bottom wall of the sleeve 84 and the water of the L-shaped plate 83... Each flat-end inner cavity is provided with a connecting groove 810. A drive gear 812 that meshes with a gear tooth 811 is rotatably connected in the connecting groove 810 located in the L-shaped plate 83. A drive rod 813 is installed on the middle part of the drive gear 812 near the central axis of the rotating drum 41. A drive positioning rod 814 is installed on the bottom wall of the drive rod 813 away from the drive gear 812. A through slot 815 adapted to the drive rod 813 is provided at the top of the linkage groove 80 of the tube body 1. A spring-type bending groove 816 is provided on the inner wall of the through slot 815. The drive positioning rod 814 is slidably connected on the bending groove 816. Each set of outer ring parts 85 is provided with a cleaning rod 817 along the outer side of the central axis of the rotating drum 41. Each set of cleaning rods 817 is arranged in a ring array and each set of cleaning rods 817 is inclined.

[0063] During operation, after the moisture detection head 42 passes through the first desludge assembly 7, the detector and the inclined sleeve 44 come into contact with the outer ring 85. Then, as the moisture detection head 42 continues to extend outside the tube body 1, the outer ring 85 just extends outside the tube body 1. At this time, the second compression spring 81 enters the expansion state, which helps to prevent the external soil from accumulating in the dead corner between the detector and the inclined sleeve 44. When the moisture detection head 42 retracts, the elastic potential energy of the second compression spring 81 is released at the same time. Then, the L-shaped plate 83 and the sleeve 84 are reset. At this time, the outer ring 85 extends out from the detector and the outer ring 85. During the extension process, most of the soil will be cleaned from the detector and the inclined sleeve 44, preventing the soil from adhering between the detector and the inclined sleeve 44 and entering the inside of the tube body 1.

[0064] During the reset process of sleeve 84, the drive positioning rod 814 on drive rod 813 rotates along the bending groove 816 and drives drive rod 813 to rotate, which in turn drives drive gear 812 and gear teeth 811 to rotate synchronously. This facilitates the cleaning of soil on the outer surface of moisture detection head 42 and inclined sleeve 44 by cleaning rod 817, preventing the detection of the original soil during the conversion detection process, thereby reducing the accuracy of the detection.

[0065] It is worth noting that the cleaning rods 817 of the present invention are all inclined, which is conducive to the rotation of the cleaning rods 817 on the outer surface of the moisture detection head 42 and the inclined sleeve 44, and to the rapid removal of the rotating soil from the cleaning rods 817, thereby improving the cleaning effect of the present invention and further enhancing the soil cleaning force.

[0066] Example 6:

[0067] The technical solution is basically the same as that in Embodiment 1, except that... Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, an impact plate 722 is installed on the top of the T-shaped plate 72 away from the central axis of the rotating cylinder 41. The impact plate 722 is pressed against the sleeve 84. The L-shaped plate 83 has a sliding groove between its horizontal and vertical ends. The outer wall of the rotating cylinder 41 away from its central axis has a chamfered groove 76.

[0068] During operation, when the moisture detection head 42 is resetting, the elastic potential energy of the reset spring 71 is released, causing the T-plate 72 to bounce upward. At this time, the impact plate 722 on the T-plate 72 will generate an impact force on the sleeve 84, which helps to vibrate the soil adhering to the cleaning rod 817 and slide the soil on the cleaning rod 817 through the chamfered groove 76. When the moisture detection head 42 is resetting, the circular elastic material 75 will slide the soil on the moisture detection head 42 and the inclined sleeve 44 through the sliding groove and into the chamfered groove 76 to slide out of the tube body 1, which helps to automatically remove some of the soil from the outside.

[0069] Example 7:

[0070] The technical solution is basically the same as that in Embodiment 1, except that... Figure 3 , Figure 12 , Figure 13 and Figure 14As shown, the sealing assembly 9 includes three sets of spring telescopic rods 91, which are respectively installed at the rear end and left and right ends of the rotating cylinder 41. A vertically arranged second arc-shaped connecting plate 92 is installed at the end of each spring telescopic rod 91 away from the rotating cylinder 41. The second arc-shaped connecting plate 92 is tightly attached to the inner wall of the tube body 1. A sealing ring 93 is installed in each set of through holes 43 on the second arc-shaped connecting plate 92. A first L-shaped moving part 94 and a second L-shaped moving part 95 are respectively installed at the upper and lower ends of the second arc-shaped connecting plate 92 and the first arc-shaped connecting plate 92. The vertical ends of the first L-shaped moving parts 94 and 95 slide through the inner side of the rotating cylinder 41. The upper and lower ends of the rotating cylinder 41 are provided with a circular array of moving grooves 96. The first L-shaped moving parts 94 and 95 are located at the moving... A movable connector 97 is installed on one side of the groove 96. A first pulley 98 is rotatably connected to the left and right sides of the movable connector 97 located at the front end of the rotating drum 41. A V-block 99 is rotatably connected to the left and right sides of the movable connector 97 located at the front end of the rotating drum 41. A first wire rope 910 passing through the first pulley 98 is connected between the left and right sides of the movable connector 97 located at the front end and one side of the V-block 99. A movable drive rod 911 is installed on the movable connector 97 located on the left and right sides. The other side of the V-block 99 is slidably connected to the movable drive rod 911. A second pulley 912 is rotatably connected to the rear side of the movable connector 97 located at the left and right ends of the rotating drum 41. A second wire rope 913 passing through the second pulley 912 is connected between the movable connector 97 located at the rear end and the movable connector 97 located at the left and right ends.

[0071] When the telescopic component 5 drives the first arc-shaped connecting plate 52 back to its original position, the two second L-shaped moving parts 95 connected to it drive the moving connecting head 97 located at the front end to move along the moving groove 96. Then, with the cooperation of the first pulley 98 and the first wire rope 910, the V-shaped blocks 99 at both ends are driven to rotate. At this time, the V-shaped blocks 99 on both sides drive the moving drive rod 911 to move closer along the central axis of the rotating drum 41, thereby driving the second arc-shaped connecting plates 92 at both ends to retract. At the same time, when the moving drive rod 911 at both ends drives the moving connecting head 97 connected to it to move, with the cooperation of the second pulley 912 and the second wire rope 913, the moving connecting head 97 located at the rear end is driven closer to the central axis of the rotating drum 41, thereby realizing the retraction of the second arc-shaped connecting plate 92 at the rear end. This makes it convenient to extend the sealing ring 93 to different positions for sealing when changing different orientations, which is beneficial to further improve the sealing performance of the tube body 1 and prevent external moisture and soil from entering the tube body 1 and affecting the accuracy of the detector.

[0072] Working principle: This high-precision landslide emergency early warning device should be used according to the following steps:

[0073] First, place the device in the soil trough on the landslide, then align the soil with the mounting plate 2, and fix the mounting plate 2 to the soil with bolts. When detecting soil moisture in different locations, start the drive motor 4 and rotate the drum 41 on the tube 1 until the moisture detection head 42 is aligned with one of the through holes 43. Drive the electric push rod 51, and then drive the first arc-shaped connecting plate 52 to extend and retract the moisture detection head 42 along the through hole 43. Then close the electric push rod 51 and support the moisture detection head 42 with the expansion spring 54 to reduce waste of the electric push rod 51. When the moisture detection head 42 is inside the tube 1, the expansion spring 54 and the limiting plate 53 drive the moisture detection head 42 to squeeze against the inner wall of the tube 1 and make contact with the soil through the detector. The data detected by the detector is transmitted to the controller 3. When the detected data exceeds the preset value, the alarm will alert people around and the data will be transmitted to the terminal wirelessly so that the staff can analyze the surrounding landslide.

[0074] Second, as the moisture detection head 42 extends out of the through hole 43, its cover plate 63 rotates along the rotating shaft 62 and retracts in the square groove 60. Then, the rotating plate 65 rotates on the vertical plate 64, causing the first compression spring 67 to enter the expansion state. When the moisture detection head 42 retracts, the elastic potential energy of the first compression spring 67 is released, causing the rotating plate 65 and the vertical plate 64 to return to their original positions, thereby causing the cover plate 63 to automatically reset, to prevent external soil from entering the through hole 43.

[0075] Third, as the inclined sleeve 44 on the moisture detection head 42 moves within the through hole 43, it first contacts the T-shaped plate 72 and drives the T-shaped plate 72 to retract into the auxiliary groove under pressure. During the retraction of the T-shaped plate 72, the elastic waterproof material 73 is driven to unfold in the through hole 43 until the moisture detection head 42 passes through the middle of the elastic waterproof material 73. At this time, the cooperation between the elastic rope 74 and the circular elastic material 75 helps to prevent external impurities and moisture from entering the tube body 1. Moreover, during the retraction of the moisture detection head 42, it is beneficial to clean the excess soil on the moisture detection head 42.

[0076] Fourth, after the moisture detection head 42 passes through the first desludge assembly 7, the detector and the inclined sleeve 44 contact the outer ring 85. Then, as the moisture detection head 42 continues to extend outside the tube body 1, the outer ring 85 just extends outside the tube body 1. At this time, the second compression spring 81 enters the expanded state, which helps to prevent the accumulation of external soil in the dead corner between the detector and the inclined sleeve 44. When the moisture detection head 42 retracts, the elastic potential energy of the second compression spring 81 is released simultaneously. Then, the L-shaped plate 83 and the sleeve 84 reset. At this time, the outer ring 85 extends out from the detector and the outer ring 85. During the extension process, most of the soil will be cleaned from the detector and the inclined sleeve 44 to prevent it from adhering between the detector and the inclined sleeve 44 and entering the inside of the tube body 1. During the reset process of the sleeve 84, the drive positioning rod 814 on the drive rod 813 is positioned and rotated along the bending groove 816, and drives the drive rod 813 to rotate, which in turn drives the drive gear 812 and the gear teeth 811 to rotate synchronously. This is beneficial for cleaning the soil on the outer surface of the moisture detection head 42 and the inclined sleeve 44 through the cleaning rod 817, preventing the original soil from being detected during the conversion detection process, thereby reducing the detection accuracy.

[0077] Fifth, when the telescopic component 5 drives the first arc-shaped connecting plate 52 back to its original position, the two second L-shaped moving parts 95 connected to it drive the moving connecting head 97 located at the front end to move along the moving groove 96. Then, with the cooperation of the first pulley 98 and the first wire rope 910, the V-shaped blocks 99 at both ends are driven to rotate. At this time, the V-shaped blocks 99 on both sides drive the moving drive rod 911 to move closer along the central axis of the rotating drum 41, thereby driving the second arc-shaped connecting plates 92 at both ends to retract. At the same time, when the moving drive rod 911 at both ends drives the moving connecting head 97 connected to it to move, with the cooperation of the second pulley 912 and the second wire rope 913, the moving connecting head 97 located at the rear end is driven to move closer to the central axis of the rotating drum 41, thereby realizing the retraction of the second arc-shaped connecting plate 92 at the rear end. This allows the sealing ring 93 to be extended to different positions for sealing when changing different orientations.
