Description

TECHNICAL FIELD

[0001] The present application relates to the field of water conservancy engineering slope construction protection technology, in particular to a slope protection system for water conservancy engineering. BACKGROUND

[0002] At present, the safety of water conservancy engineering is closely related to the degree of slope, reservoir slope and river slope: (1) Excavated slope: excavated slope is the slope formed by human activities in water conservancy and hydropower engineering construction, such as tunnel entrance and exit and its vicinity, spillway, dam abutment and its vicinity, ship lock, ground power station plant, hub area highway and other permanent excavated slope, as well as temporary slope excavated by hub area buildings. This kind of slope is generally directly related to engineering safety. (2) Reservoir slope: after the reservoir is filled with water, reservoir bank collapse is a common phenomenon. Whether this kind of slope instability will threaten the safety of engineering is related to the distance from the engineering, scale and so on. In the water conservancy and hydropower engineering built in the navigable river, the instability of slope may also threaten the safety of navigation. In a water conservancy and hydropower engineering, the reservoir slope is often large in quantity and scale, and the processing workload and cost may be large. (3) River slope: the disaster caused by the instability of this kind of slope is more suitable to be classified as natural disaster. In general, it has nothing to do with whether the water conservancy and hydropower engineering is built. The river slope has nothing to do with whether the water conservancy and hydropower engineering is built. The excavated slope of the engineering is generally more closely related to the water conservancy engineering and cannot be ignored.

[0003] For the related technology in the above, the inventor believes that in general, after the slope of water conservancy engineering is built, the foundation fence is installed to prompt the surrounding personnel not to approach; but since it is a foundation fence, its protection is not high, and if some personnel walk beside the fence, it is also possible that they will accidentally fall on the slope of water conservancy engineering. Since the slope surface has high inclination and falling on the slope will directly slide into the reservoir or dam to cause drowning, the danger is great, so the overall safety and stability of the slope protection of water conservancy slope is not high. SUMMARY

[0004] In order to improve the problem that the safety and stability of the slope of water conservancy engineering is not high, the purpose of the present application is to provide a slope protection system for water conservancy engineering.

[0005] The slope protection system for water conservancy engineering provided by the present application adopts the following technical scheme:

[0006] The utility model provides a kind of slope protection system for hydraulic engineering, including fence, heightening mechanism and blocking mechanism;The fence is vertically combined by multiple vertical pipes and multiple horizontal pipes, and heightening mechanism and blocking mechanism are installed on each vertical pipe;Pressure sensing mechanism is installed at the ground outside dam or reservoir, and the pressure sensing mechanism is electrically connected with heightening mechanism and blocking mechanism;When the pressure sensing mechanism senses the pressure of pedestrian stepping, the pressure sensing mechanism drives heightening mechanism to rise from vertical pipe and drives blocking mechanism to prevent pedestrian from further approaching fence.

[0007] By adopting the above technical scheme, when pedestrians approach the fence, they will first touch the pressure sensing mechanism, which will receive a pressure signal and drive the heightening mechanism to rise. The heightening mechanism on the fence will then vertically rise, further preventing pedestrians from crossing the fence. Moreover, the blocking mechanism will also be activated under the drive of the pressure sensing mechanism, making it impossible for pedestrians to continue approaching the fence. At this time, pedestrians can only stay far away from the dam or reservoir. With the obstruction of the heightening mechanism and the blocking mechanism, pedestrians cannot approach the dam or reservoir, making it less likely for them to fall into the dam or reservoir, thereby improving the safety and stability of the slope of the dam or reservoir.

[0008] Optionally, the pressure sensing mechanism includes a stepping sensing component and a driving component. The stepping sensing component is installed above the ground outside the dam or reservoir, and the driving component is installed below the ground outside the dam or reservoir and at the bottom of the vertical pipe. When the stepping sensing component senses the stepping pressure of pedestrians, it drives the driving component to start, so that the driving component drives the heightening mechanism to move vertically upward in the vertical pipe.

[0009] By adopting the above technical scheme, when pedestrians stand on the stepping sensing component, the stepping sensing component senses the stepping pressure of pedestrians and receives a pressure signal, thereby driving the driving component to start. The driving component can then drive the heightening mechanism to move vertically upward in the vertical pipe, achieving the effect of automatically raising the heightening mechanism to obstruct pedestrians when they approach the dam or reservoir.

[0010] Optionally, the stepping sensing component includes a stepping plate, a pressure sensor and a controller. The pressure sensor is installed on the surface of the stepping plate. The stepping plate has a mounting cavity, and the controller is installed in the mounting cavity. The pressure sensor is electrically connected with the controller, and the controller is connected with the driving component. After the pressure sensor receives a pressure signal, it is transmitted to the controller, and the controller drives the driving component to start.

[0011] By adopting the technical scheme, when the pedestrian stands on the treadle, the pressure sensor receives the pressure signal and transmits the pressure signal to the controller, and the controller actively drives the driving assembly to start after receiving the pressure signal, so that the driving assembly is automatically started conveniently.

[0012] Optionally, the driving assembly comprises a battery and a reset cylinder, the reset cylinder is installed in the pipe segment of the vertical pipe below the ground, and the piston rod of the reset cylinder extends vertically upward; the battery is installed below the ground on one side of the vertical pipe, the battery is electrically connected with the reset cylinder and the controller respectively, and the controller is used to drive the opening and closing of the battery after receiving the pressure signal.

[0013] By adopting the technical scheme, when the controller receives the pressure signal, the switch of the battery is opened, so that the battery supplies electric energy to the reset cylinder, the reset cylinder is started after receiving the electric energy, so that the piston rod of the reset cylinder is elongated, and the reset cylinder is started conveniently.

[0014] Optionally, the height increasing mechanism comprises a height increasing rod, the height increasing rod is vertically inserted in the vertical pipe, and the driving assembly is used to drive the height increasing rod to ascend and descend in the vertical direction.

[0015] By adopting the technical scheme, after the piston rod of the reset cylinder is elongated, the height increasing rod is directly pushed to move vertically upward along the length direction of the vertical pipe, so that one end of the height increasing rod is pushed out from the upper end of the vertical pipe, and the height of the entire fence is increased.

[0016] Optionally, the blocking mechanism comprises a pushing assembly and a rotating blocking assembly, the pushing assembly is installed on the vertical pipe, the rotating blocking assembly is provided with a plurality of groups along the length direction of the vertical pipe; the driving assembly is also used to drive the pushing assembly to start; after the pushing assembly starts, the plurality of rotating blocking assemblies are driven to change from the state of not blocking the pedestrian from approaching the fence to the state of blocking the pedestrian from approaching the fence.

[0017] By adopting the technical scheme, after the piston rod of the reset cylinder is elongated, the pushing assembly is simultaneously driven to operate, and the pushing assembly drives the rotating blocking assembly to operate, at this time, as the piston rod of the reset cylinder is gradually elongated, the plurality of rotating blocking assemblies change from the state of not blocking the pedestrian from approaching the fence to the state of blocking the pedestrian from approaching the fence, so that the pedestrian cannot continue to approach the fence, and the effect that the pedestrian is prevented from approaching the dam or the reservoir is achieved directly and conveniently.

[0018] Optionally, the pushing assembly comprises a pushing rod, a spring, a pushed block and an extension plate; a plurality of openings are formed on the vertical pipe along the length direction of the vertical pipe, the openings are transversely formed on the vertical pipe and pass through the vertical pipe from inside to outside, the pushed block is slidingly inserted into the openings, a slot is formed on the upper and lower hole walls of the openings, the length direction of the slot is consistent with the length direction of the opening, the extension plate is arranged on the outer wall of the pushed block and extends into the slot; the spring is installed between the inner end wall of the slot and the extension plate, the spring makes the pushed block always have a tendency to move into the vertical pipe; the driving assembly is used for driving the pushing rod to move in the vertical direction, and the pushing rod is used for pushing the pushed block to move horizontally from inside the vertical pipe to outside the vertical pipe; after the pushed block is partially pushed out of the opening, the rotation blocking assembly changes from the state of not blocking pedestrians from approaching the fence to the state of blocking pedestrians from approaching the fence.

[0019] By adopting the above technical scheme, after the piston rod of the reset electric cylinder is elongated, the pushing rod is pushed to move vertically upward, and the pushing rod in movement pushes the pushed block horizontally to the outside of the vertical pipe, at this time, the extension plate moves synchronously in the slot and presses the spring, so that the spring is in a compressed state; during the process that the pushed block is partially moved horizontally from inside the vertical pipe to outside the vertical pipe, the rotation blocking assembly changes from the state of not blocking pedestrians from approaching the fence to the state of blocking pedestrians from approaching the fence, so that the pedestrians cannot continue to approach the fence, and at this time, the pedestrians can be blocked.

[0020] Optionally, an inclined pushing surface is arranged on the pushing rod and slidingly matches the inclined pushed surface.

[0021] By adopting the above technical scheme, when the pushing rod moves vertically upward, the inclined pushing surface first adheres to the inclined pushed surface, and with the continuous movement of the pushing rod, the inclined pushing surface occupies the position of the inclined pushed surface in the vertical pipe, so as to completely press the one end of the pushed block in the vertical pipe into the opening, and at this time, the pushed block realizes horizontal movement in the opening, and the effect that the movement of the pushed block is more intuitive and convenient is achieved.

[0022] Optionally, the rotation blocking assembly comprises a rotation sleeve, a rotation column, an extension pipe body, a torsion spring, a pushing baffle and a state conversion seat; the rotation column is vertically installed on the outer wall of the vertical pipe near the opening; the rotation sleeve is sleeved on the rotation column; the extension pipe body is hingedly arranged on the outer wall of the rotation sleeve; the pushing baffle is arranged on the outer wall of the rotation sleeve and below the extension pipe body; the state conversion seat is installed on the vertical pipe near the rotation sleeve; the lower pipe wall of the extension pipe body is always in contact with the state conversion seat; when the plate surface of the pushing baffle is parallel to the opening surface of the opening, the extension pipe body is in an inclined state of being in contact with the fence and the end of the extension pipe body away from the rotation sleeve is at the highest end of the inclination; when the plate surface of the pushing baffle is perpendicular to the opening surface of the opening, the extension pipe body is in an inclined state and extends towards the side away from the dam or the reservoir, and the end of the extension pipe body away from the rotation sleeve is at the lowest end of the inclination; the torsion spring is installed between the rotation sleeve and the rotation column and makes the extension pipe body always have a tendency to rotate towards the direction of being in contact with the fence.

[0023] By using the above technical scheme, when the plate surface of the pushing baffle is parallel to the opening surface of the opening, the extension pipe body is also in a state of being in contact with the fence; when the pushed block gradually moves out of the opening, the pushed block forcibly pushes the pushing baffle, so that the pushing baffle changes from the state of being parallel to the opening of the opening to the state of being perpendicular to the opening of the opening, and the extension pipe body changes from the state of being in contact with the fence to the state of one end extending towards the side away from the dam or the reservoir; because the extension pipe bodies all extend towards the side away from the dam or the reservoir, pedestrians cannot continue to approach the fence; thus, the effect that the extension pipe body is conveniently driven to rotate is achieved.

[0024] Optionally, the extension pipe body is composed of a plurality of extension pipe segments with different diameters and is axially slidably connected; the upper surface of the state conversion seat is provided with an inclined contact surface, which comprises an inclined downward contact surface, a transition surface and an inclined upward contact surface in sequence; when the plate surface of the pushing baffle is parallel to the opening surface of the opening, the lower pipe wall of the extension pipe segment closest to the rotation sleeve is in contact with the inclined upward contact surface, and the height of the contact position is higher than the hinge position of the rotation sleeve and the extension pipe segment; when the plate surface of the pushing baffle is perpendicular to the opening surface of the opening, the lower pipe wall of the extension pipe segment closest to the rotation sleeve is in contact with the inclined downward contact surface, and the height of the contact position is lower than the hinge position of the rotation sleeve and the extension pipe segment.

[0025] By adopting the technical scheme, when the telescopic pipe body is entirely in the state of being attached to the fence, the lower pipe wall of the telescopic pipe segment closest to the rotating sleeve is attached to the upward-tilted attachment surface, and the height of the attachment position is higher than the hinge position of the rotating sleeve and the telescopic pipe segment, so the height of the telescopic pipe body gradually increases from the end close to the rotating sleeve to the end away from the rotating sleeve; since the telescopic pipe body is formed by the axial sliding connection of the multiple telescopic pipe segments with different pipe diameters, under the action of gravity, the multiple telescopic pipe segments will gradually shrink and move close to the telescopic pipe segment close to the rotating sleeve, so that the telescopic pipe body is in the storage and shortening state; when the telescopic pipe body also changes from the state of being attached to the fence to the state of one end being directed away from the dam or reservoir side, the lower pipe wall of the telescopic pipe segment closest to the rotating sleeve is attached to the downward-tilted attachment surface, and the height of the attachment position is lower than the hinge position of the rotating sleeve and the telescopic pipe segment, so the height of the telescopic pipe body gradually decreases from the end close to the rotating sleeve to the end away from the rotating sleeve; since the telescopic pipe body is formed by the axial sliding connection of the multiple telescopic pipe segments with different pipe diameters, under the action of gravity, the multiple telescopic pipe segments will gradually move out of the adjacent telescopic pipe segments, so that the entire telescopic pipe body is lengthened, at this time, the pedestrian can be blocked at a distance from the fence and cannot proceed further, and the protection effect is further improved.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] 1. When a pedestrian approaches the fence, the pedestrian will first touch the pressure sensing mechanism, at this time, the pressure sensing mechanism will receive a pressure signal and drive the heightening mechanism to rise, at this time, the heightening mechanism on the fence will vertically rise, further preventing the pedestrian from crossing the fence; and the blocking mechanism will also be started under the drive of the pressure sensing mechanism, so that the pedestrian cannot continue to approach the fence, at this time, the pedestrian can only be far away from the dam or reservoir; the pedestrian cannot approach the dam or reservoir under the obstruction of the heightening mechanism and the blocking mechanism, so the pedestrian is not easy to fall into the dam or reservoir, thereby achieving the effect of improving the low safety and stability of the slope of the dam or reservoir;

[0028] 2. When the plate surface of the push plate is parallelly covered on the opening surface of the opening, the telescopic pipe body is also entirely in the state of being attached to the fence; at this time, when the pushed block gradually moves out of the opening, the pushed block will forcibly push the push plate, so that the push plate changes from the state of being parallel to the opening of the opening to the state of being perpendicular to the opening of the opening, and the telescopic pipe body also changes from the state of being attached to the fence to the state of one end being directed away from the dam or reservoir side; since the multiple telescopic pipe bodies are all in the state of one end being directed away from the dam or reservoir side, the pedestrian cannot continue to approach the fence; thereby achieving the effect of conveniently driving the telescopic pipe body to rotate;

[0029] 3. When the telescopic pipe body is entirely in the state of being attached to the fence, the height of the telescopic pipe body gradually increases from the end close to the rotating sleeve to the end away from the rotating sleeve, because the lower pipe wall of the telescopic pipe segment closest to the rotating sleeve is attached to the upwardly inclined attachment surface and the height of the attachment is higher than the hinge between the rotating sleeve and the telescopic pipe segment; and because the telescopic pipe body is composed of multiple telescopic pipe segments with different diameters that are connected in axial sliding, under the action of gravity, the multiple telescopic pipe segments will gradually shrink onto the telescopic pipe segment close to the rotating sleeve, so that the telescopic pipe body is in a storage and shortened state; and when the telescopic pipe body also changes from the state of being attached to the fence to the state of one end being away from the dam or reservoir side, the height of the telescopic pipe body gradually decreases from the end close to the rotating sleeve to the end away from the rotating sleeve, because the lower pipe wall of the telescopic pipe segment closest to the rotating sleeve is attached to the downwardly inclined attachment surface and the height of the attachment is lower than the hinge between the rotating sleeve and the telescopic pipe segment; and because the telescopic pipe body is composed of multiple telescopic pipe segments with different diameters that are connected in axial sliding, under the action of gravity, the multiple telescopic pipe segments will gradually move out of the adjacent telescopic pipe segments, so that the entire telescopic pipe body is lengthened, at this time, pedestrians can be blocked from advancing at a distance from the fence, further improving the protection effect.

[0039] Referring to Figure 1 , 2, the pressure sensing mechanism 6 comprises a stepping sensing assembly 61 and a driving assembly 62, the stepping sensing assembly 61 is installed above the ground outside the dam or reservoir, and the driving assembly 62 is installed below the ground outside the dam or reservoir and at the bottom of the stand pipe 2 inserted below the ground; when the stepping sensing assembly 61 senses the stepping pressure of the pedestrian, the stepping sensing assembly 61 drives the driving assembly 62 to start, so that the driving assembly 62 drives the heightening mechanism 4 to move vertically upward in the stand pipe 2.

[0040] In combination Figure 2 , specifically, the stepping sensing assembly 61 comprises a stepping plate 611, a pressure sensor 612 and a controller 613, the stepping plate 611 is placed on the ground outside the dam or reservoir, and the height of the upper plate surface of the stepping plate 611 is higher than the ground; a plurality of installation grooves are formed on the upper plate surface of the stepping plate 611, and one pressure sensor 612 is installed in each installation groove, that is, the upper plate surface of the entire stepping plate 611 can be covered by the contact surface of the pressure sensor 612, and once the pedestrian steps on the stepping plate 611, the pedestrian can be sensed by the pressure sensor 612; an installation cavity is formed in the inside of the stepping plate 611, and the controller 613 is installed in the installation cavity; the pressure sensor 612 is electrically connected with the controller 613, and the controller 613 is connected with the driving assembly 62; after the pressure sensor 612 receives the pressure signal, the pressure signal is transmitted to the controller 613, and the controller 613 drives the driving assembly 62 to start. The driving assembly 62 comprises a storage battery 621 and a reset electric cylinder 622, the reset electric cylinder 622 is installed in the pipe section of the stand pipe 2 below the ground, and the piston rod of the reset electric cylinder 622 extends vertically upward in the stand pipe 2; the storage battery 621 is installed below the ground on one side of the stand pipe 2. It is worth noting that the storage battery 621 is covered in a protective box. The storage battery 621 is electrically connected with the reset electric cylinder 622 and the controller 613 respectively, and the controller 613 is used to drive the storage battery 621 to start and stop after receiving the pressure signal, that is, after the controller 613 receives the pressure signal, the storage battery 621 is driven to be in the power transmission state; and when no pressure signal is received, the storage battery 621 is driven to be in the power-off state.

[0041] When the pedestrian stands on the stepping sensing assembly 61, the stepping sensing assembly 61 senses the stepping pressure of the pedestrian and receives the pressure signal, so as to drive the driving assembly 62 to start, and the driving assembly 62 can drive the heightening mechanism 4 to move vertically upward in the stand pipe 2, so as to achieve the effect that the heightening mechanism 4 is automatically raised to block when the pedestrian approaches the dam or reservoir.

[0042] In combination Figure 2 , 3The height increasing mechanism 4 comprises a height increasing rod 41 vertically inserted into the vertical pipe 2, and the driving assembly 62 is used to drive the height increasing rod 41 to vertically ascend and descend; that is, a pushing plate body is arranged at the end of the piston rod of the reset electric cylinder 622, the lower end of the height increasing rod 41 is connected with the pushing plate body, and when the reset electric cylinder 622 receives the electric energy of the battery 621, the piston rod of the reset electric cylinder 622 is elongated, the pushing plate body vertically moves upward, and the height increasing rod 41 vertically moves upward; and it is worth noting that the length of the height increasing rod 41 is longer than the length of the vertical pipe 2, that is, one end of the height increasing rod 41 is outside the upper end opening of the vertical pipe 2 by default, and a warning sign (not shown in the figure) is arranged at the end of the height increasing rod 41 outside the vertical pipe 2, which can assist in warning pedestrians from the side, so as to avoid pedestrians from further approaching.

[0043] With reference to Figure 2 、 3 The blocking mechanism 5 comprises a pushing assembly 51 and a rotating blocking assembly 52, the pushing assembly 51 is installed on the vertical pipe 2, and the rotating blocking assembly 52 is provided with a plurality of groups along the length direction of the vertical pipe 2; the driving assembly 62 is also used to drive the pushing assembly 51 to start; after the pushing assembly 51 starts, it is used to drive a plurality of rotating blocking assemblies 52 to change from a state of not blocking pedestrians from approaching the fence 1 to a state of blocking pedestrians from approaching the fence 1. Specifically, the pushing assembly 51 comprises a pushing rod 511, a spring 512, a pushed block 513 and an extension plate 514; a plurality of openings 21 are equidistantly opened on the vertical pipe 2 along the length direction of the vertical pipe 2, the pipe wall of the vertical pipe 2 is thick, the openings 21 are horizontally opened on the pipe wall of the vertical pipe 2, and the vertical pipe 2 is communicated with the outside through the openings 21; the pushed block 513 is slidingly inserted into the opening 21; a slot 211 is opened on the upper and lower hole walls of the opening 21 along the length direction of the opening 21, the extension plate 514 is arranged on the outer wall of the pushed block 513 and extends into the slot 211, one end of the spring 512 is connected to the inner end wall of the slot 211, the other end is connected with the block surface of the pushed block 513, and the spring 512 always has a tendency to move horizontally into the vertical pipe 2;

[0044] The driving assembly 62 is used to drive the pushing rod 511 to move in the vertical direction, and the pushing rod 511 is used to push the pushed block 513 to move horizontally from inside the vertical pipe 2 to outside the vertical pipe 2, that is, the pushing rod 511 is vertically installed on the pushing plate at the end of the piston rod of the reset electric cylinder 622, an inclined pushing surface 5111 is arranged on the pushing rod 511, and an inclined pushing surface 5131 is arranged at one end of the pushed block 513 close to the vertical pipe 2; after the pushed block 513 is partially pushed out of the opening 21, the rotating blocking assembly 52 changes from the state of not blocking pedestrians from approaching the fence 1 to the state of blocking pedestrians from approaching the fence 1; and when the pushed block 513 returns to the original state, the rotating blocking assembly 52 changes from the state of blocking pedestrians from approaching the fence 1 to the state of not blocking pedestrians from approaching the fence 1. In order to make the sliding between the inclined pushing surface 5131 and the inclined pushing surface 5111 more smooth, polytetrafluoroethylene is arranged on the inclined pushing surface 5131 and the inclined pushing surface 5111.

[0045] After the piston rod of the reset electric cylinder 622 is extended, the pushing rod 511 is pushed to move vertically upward, and the moving pushing rod 511 pushes the pushed block 513 to move horizontally to the outside of the vertical pipe 2, at this time, the extension plate 514 moves synchronously in the slot 211 and presses the spring 512, so that the spring 512 is in a compressed state; during the process that the pushed block 513 is partially horizontally moved from inside the vertical pipe 2 to outside the vertical pipe 2, the rotating blocking assembly 52 changes from the state of not blocking pedestrians from approaching the fence 1 to the state of blocking pedestrians from approaching the fence 1, so that the pedestrians cannot continue to approach the fence 1, at this time, the effect of blocking pedestrians can be achieved; when the piston rod of the reset electric cylinder 622 is shortened, the pushing rod 511 gradually moves downward and no longer occupies the position of the pushed block 513, because the spring 512 is in a compressed state, under the action of its own elastic force, the spring 512 quickly drives one end of the pushed block 513 to return to the vertical pipe 2, at this time, the rotating blocking assembly 52 is no longer pressed by the pushed block 513, and changes from the state of blocking pedestrians from approaching the fence 1 to the state of not blocking pedestrians from approaching the fence 1; thereby achieving the effect that the rotating blocking assembly 52 automatically changes the blocking state according to whether pedestrians approach.

[0047] With reference to Figure 5 , 6 The profile of the state conversion seat 526 is annular, and the upper surface of the state conversion seat 526 is provided with an inclined attachment surface 7, which is composed of an inclined downward attachment surface 71, a transition surface 72 and an inclined upward attachment surface 73 in sequence; and the extension pipe body 523 is composed of a plurality of extension pipe segments 5231 with different diameters which are axially slidably connected, and in this embodiment, the diameter of the extension pipe segment 5231 closest to the rotating sleeve 521 is the largest, and the lower pipe wall of the extension pipe segment 5231 closest to the rotating sleeve 521 is always attached to the inclined attachment surface 7; and the pipe opening end of the extension pipe segment 5231 is provided with an anti-falling flange, and the pipe opening outer wall of the adjacent extension pipe segment 5231 with a smaller diameter is provided with an anti-falling ring, and the anti-falling ring and the anti-falling flange are opposite to each other in the axial direction of the extension pipe segment 5231, so as to prevent the adjacent two extension pipe segments 5231 from being separated from each other.

[0048] With reference to Figure 4 , 6, push the baffle 525 and the position state relationship of telescopic tube body 523 as follows: in the push baffle 525 board surface parallel cover in the opening 21 opening face, the telescopic tube body 523 on the most close to the rotating sleeve 521 that the telescopic tube section 5231 lower tube wall and state conversion seat 526 on the inclined upward fit face 73 fit, and at this time the telescopic tube section 5231 and the height of the fit place of inclined upward fit face 73 is higher than the hinge of rotating sleeve 521 and telescopic tube section 5231; The entire tube body of telescopic tube body 523 is in the inclined state of fitting in the fence 1, and at this time the end of telescopic tube body 523 away from rotating sleeve 521 is the highest end of inclination, at this time under the action of gravity, telescopic tube section 5231 will automatically slide to the adjacent telescopic tube section 5231 with larger diameter to contract, so that the entire telescopic tube body 523 is in the telescopic state;

[0049] When the push block 513 continues to move out of the opening 21 to gradually push the push baffle 525 away, so that the board surface of the push baffle 525 is perpendicular to the opening face of the opening 21, the lower tube wall of the telescopic tube section 5231 on the telescopic tube body 523 closest to the rotating sleeve 521 is fitted with the inclined downward fit face 71 on the state conversion seat 526, and at this time the height of the fit place of the telescopic tube section 5231 and the inclined downward fit face 71 is lower than the hinge of the rotating sleeve 521 and the telescopic tube section 5231, the entire tube body of the telescopic tube body 523 is in the state of extending away from the dam or reservoir side, and at this time the end of the telescopic tube body 523 away from the rotating sleeve 521 is the lowest end of inclination, at this time under the action of gravity, the telescopic tube section 5231 with smaller diameter will automatically slide out of the adjacent telescopic tube section 5231 with larger diameter, so that the entire telescopic tube body 523 is in the elongated state; The elongated telescopic tube body 523 will separate the fence 1 from the pedestrians by a certain distance, thereby preventing pedestrians from approaching the fence 1. The transition surface 72 of the state conversion seat 526 is to facilitate the smooth transition of the telescopic tube section 5231 from the state of fitting in the inclined upward fit face 73 to the state of fitting in the inclined downward fit face 71 (and vice versa) while the telescopic tube body 523 rotates with the rotating sleeve 521.

[0050] Referring to Figure 6 , the torsional spring 524 is installed between the rotating sleeve 521 and the rotating column 522, that is, the torsional spring 524 is sleeved on the rotating column 522, one end of the torsional spring 524 is connected with the outer wall of the rotating column 522, and the other end is connected with the inner wall of the rotating sleeve 521, the torsional spring 524 makes the telescopic tube body 523 always have the tendency to rotate in the direction of fitting in the fence 1.

[0051] When the telescopic pipe body 523 is entirely in the state of being attached to the fence 1, since the lower pipe wall of the telescopic pipe section 5231 closest to the rotating sleeve 521 is attached to the upwardly inclined attachment surface 73 and the height of the attachment is higher than the hinge position of the rotating sleeve 521 and the telescopic pipe section 5231, the height of the telescopic pipe body 523 gradually increases from the end close to the rotating sleeve 521 to the end away from the rotating sleeve 521; since the telescopic pipe body 523 is composed of a plurality of telescopic pipe sections 5231 with different diameters that are connected in axial sliding manner, under the action of gravity, the plurality of telescopic pipe sections 5231 will gradually contract onto the telescopic pipe section 5231 close to the rotating sleeve 521, so that the telescopic pipe body 523 is in the state of being stored and shortened; when the telescopic pipe body 523 also changes from the state of being attached to the fence 1 to the state of one end being directed away from the dam or reservoir side, since the lower pipe wall of the telescopic pipe section 5231 closest to the rotating sleeve 521 is attached to the downwardly inclined attachment surface 71 and the height of the attachment is lower than the hinge position of the rotating sleeve 521 and the telescopic pipe section 5231, the height of the telescopic pipe body 523 gradually decreases from the end close to the rotating sleeve 521 to the end away from the rotating sleeve 521; since the telescopic pipe body 523 is composed of a plurality of telescopic pipe sections 5231 with different diameters that are connected in axial sliding manner, under the action of gravity, the plurality of telescopic pipe sections 5231 will gradually move out of the adjacent telescopic pipe sections 5231 autonomously, so that the entire telescopic pipe body 523 is lengthened, at this time, the pedestrians can be blocked from advancing at a distance far from the fence 1, further improving the protection effect.

[0052] The implementation principle of the embodiment of the present application is as follows: when the pedestrian gradually approaches the dam or reservoir and steps on the stepping plate 611, the pressure sensor 612 on the stepping plate 611 senses the pressure and drives the reset electric cylinder 622 to start. After the reset electric cylinder 622 starts, the piston rod is elongated, the heightening rod 41 is lifted, the upper end of the heightening rod 41 penetrates the top end of the vertical pipe 2 and continues to extend upward, thereby increasing the height of the fence 1 from the side, so that the fence 1 around the dam or reservoir is more difficult to be easily climbed by the pedestrian; at the same time, the elongation of the piston rod of the reset electric cylinder 622 also pushes the push rod 511 to move vertically upward; when the push rod 511 moves vertically upward, the pushed block 513 in the opening hole 21 of the vertical pipe 2 is sequentially partially pushed out of the vertical pipe 2; when the pushed block 513 is pushed out of the opening hole 21, the push baffle 525 is pushed from the state of covering the opening surface of the opening hole 21 to the state of being perpendicular to the opening of the opening hole 21, at this time the rotating sleeve 521 drives the telescopic pipe body 523 to rotate, the telescopic pipe body 523 is smoothly rotated from the state of being attached to the upward inclined attachment surface 73 to the state of being attached to the downward inclined attachment surface 71, and the telescopic pipe body 523 also changes from the telescopic state to the elongated state, and the elongated direction is also directed away from the dam or reservoir, thereby blocking the path of the pedestrian approaching the dam or reservoir and preventing the pedestrian from continuing to move in the direction of approaching the dam or reservoir; when the pedestrian walks away and no longer steps on the stepping plate 611, the pressure sensor 612 cannot sense the pressure and automatically cuts off the power supply to the storage battery 621, the piston rod of the reset electric cylinder 622 is automatically retracted in the power-off state, the heightening rod 41 is also gradually retracted into the vertical pipe 2, and the push rod 511 no longer occupies the position of the pushed block 513 in the vertical pipe 2. Under the action of the rebound force of the spring 512, the pushed block 513 moves from the opening hole 21 into the vertical pipe 2 again, at this time the push baffle 525 is no longer pressed by the pushed block 513, under the action of the torsional force of the torsional spring 524, the rotating sleeve 521 drives the telescopic pipe body 523 to rotate, so that the telescopic pipe body 523 is attached to the fence 1 again, at this time the telescopic pipe segment 5231 changes from the state of being attached to the downward inclined attachment surface 71 to the state of being attached to the upward inclined attachment surface 73, and the telescopic pipe body 523 is automatically in the retracted state; that is, in the present application, as long as a pedestrian wants to approach the dam or reservoir and steps on the stepping plate 611, the fence 1 will automatically increase in height, and the telescopic pipe body 523 will automatically elongate in the direction of the approaching pedestrian to prevent the pedestrian from continuing to approach the fence 1; when the pedestrian walks away, the fence 1 after increasing in height will automatically restore, and the telescopic pipe body 523 will automatically retract and be attached to the fence 1, and the intelligent degree is high.

Therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
