Description

Technical Field

[0001] The present invention relates to the technical field related to environmental protection, and in particular to an intelligent dust removal device for achieving ultra-low emission management. Background Art

[0002] It is well known that in the field of environmental protection, achieving ultra-low emission management is one of the effective means to promote the improvement of environmental air quality. For example, the metallurgical industry, coking industry, cement industry, electric power industry, etc. respectively carry out targeted ultra-low emission methods, which can effectively improve the air quality.

[0003] Among them, on roads near some factory areas, a small amount of materials will be scattered on the road surface during the process of being loaded by trucks. When trucks pass by, the negative pressure formed by the tires will cause dust to rise. Dust will also be formed after wind disturbance. The current control method is to arrange multiple sets of fog piles on the roadside. The fog piles spray water mist that condenses with the dust in the air and then falls to the ground to achieve the purpose of dust reduction.

[0004] For example, an intelligent rotating fog pile system with publication number CN115870114A and announcement date of March 31, 2023, includes a rotating nozzle, a fog pile pole body and a control box; the control box includes a water tank, an electrical control box, a control module and a pump box; a high-pressure pump body is arranged in the pump box; the control module is arranged in the electrical control box, and is electrically connected to the rotating nozzle and the high-pressure pump body respectively; the high-pressure pump body is connected to the water tank and the rotating nozzle through pipelines. The control module enables the operator to remotely control the operation of the fog pile system through a host computer or a smart phone, set timing or automatic control mode; it can also monitor the operation of the fog pile system in real time, and the control module can also promptly feedback abnormal operation of the fog pile through the communication module.

[0005] The deficiency of the prior art is that after the fog pile sprays dust reduction treatment on the dust raised by the driving of vehicles and the dust formed by wind disturbance, the dust mixed with water mist falls on the ground to form a mud-water mixture, and the mud-water mixture has poor fluidity and is difficult to automatically flow into the roadside sewer, and these mud-water mixtures are not cleaned up in time. After the mud-water mixture dries, dust will still be generated by the passing of vehicles or wind, especially in hot weather, the mud-water mixture dries faster and is more likely to generate dust.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Figure 5 The present invention is further described in detail.

[0028] In the description of the present invention, it is necessary to understand that the terms "center", "length", "degree", "inside", "outside", "up", "down", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] An embodiment of the present invention provides an intelligent dust removal device for achieving ultra-low emission control, comprising a pile body 1 and a first nozzle 10 arranged on the pile body 1, the first nozzle 10 is used to spray water mist into the air, and also includes a monitoring module, which is used to monitor the air particulate matter parameters in the target area, the first nozzle 10 sprays water mist to reduce dust based on the monitoring results of the monitoring module; the second nozzle 11 sprays water to flush the road surface after the first nozzle 10 finishes its operation.

[0030] Specifically, the pile body 1 has a shape similar to a street lamp pole and is arranged beside the road. A first nozzle 10 is arranged on the pile body 1. The first nozzle 10 can spray water mist into the air. The droplets of the water mist contact and condense with the suspended dust particles in the air. As the droplets contact more and more with the dust, the overall weight of the droplets increases, and finally falls on the road surface under the action of gravity, thereby achieving the purpose of reducing dust in the air. Especially on roads near some factory areas, a small amount of material will be scattered on the road surface during the process of truck loading materials. When the truck passes by, the negative pressure formed by the tire squeeze will bring up dust, and dust will also be formed after the wind disturbance. By setting the first nozzle 10 to the area Spraying water mist into the air in the target area can better solve the dust problem, but the time and duration of the first nozzle 10 spraying water mist are difficult to control. Therefore, in this embodiment, a monitoring module is set on the pile body 1 to monitor the air particulate matter parameters of the target area, such as PM2.5 / PM10 and other data. When the monitoring module detects that the particulate matter parameters in the air in the target area exceed the target parameters, such as PM10 is greater than 100, the monitoring module transmits a signal to the first nozzle 10, and the first nozzle 10 sprays water mist to perform dust reduction operations until the particulate matter parameters in the air in the area are reduced to the target parameters. Then the first nozzle 10 stops spraying water mist.

[0031] In addition, after the droplets of water mist condense with the dust in the air to form a muddy-water mixture and fall to the road surface, the fluidity of the muddy-water mixture is poor, which will make it difficult for the accumulated muddy-water mixture to flow into the sewer beside the road. After the muddy-water mixture dries, there will still be dust problems when vehicles pass by or the wind blows. Therefore, in this embodiment, a second nozzle 11 is also provided on the pile body 1. After the first nozzle 10 completes dust reduction in the target area based on the signal of the monitoring module, the second nozzle 11 starts to spray water to flush the muddy-water mixture accumulated on the road surface, and flushes the muddy-water mixture into the sewer, thereby ensuring the cleanliness of the road surface after dust reduction and avoiding secondary dust.

[0032] The beneficial effect of this embodiment is that by setting up a monitoring module, the air on the road can be monitored in real time, especially when dust is raised by vehicles driving and wind blowing, the monitoring module can immediately transmit the signal to the first nozzle 10, and then the first nozzle 10 can spray water mist for dust reduction treatment. After the first nozzle 10 finishes working, the muddy and water mixture formed by condensation of water mist and dust falls on the road surface, and then the second nozzle 11 sprays water to flush the road surface, flushing the muddy and water mixture into the sewer, thereby avoiding the dust problem after the muddy and water mixture dries again.

[0033] In the prior art, the height of the fog pile is basically fixed, but the vehicles passing on the road are of different heights. For vehicles below the spray height of the fog pile, the purpose of spray dust reduction can be better achieved, while for vehicles above the spray height of the fog pile, the water mist sprayed by the fog pile is difficult to reach the top of the vehicle, so the dust reduction effect for such vehicles is poor. Therefore, in an optional embodiment, a lifting mechanism 2 is also included, which is used to drive the first nozzle 10 to move back and forth in the vertical direction to adjust the height of the water mist sprayed by the first nozzle 10.

[0034] Specifically, the lifting mechanism 2 can be any mechanism with linear reciprocating motion, such as a vertically arranged screw transmission mechanism, a chain transmission mechanism, etc. This is the prior art and will not be elaborated. The lifting height of the lifting mechanism 2 can be automatically adjusted according to the height of the vehicle, that is, the lifting mechanism 2 not only includes a motion module but also a vehicle monitoring module. The vehicle monitoring module monitors the passing vehicles and transmits the appearance information of the vehicle to the lifting mechanism 2. The lifting mechanism 2 drives the first nozzle 10 to move vertically until the vehicle passes. The water mist sprayed by the first nozzle 10 can be higher than the height of the vehicle, so as to better spray water mist from the roof for dust reduction. After the vehicle passes, the lifting mechanism 2 can also drive the first nozzle 10 to spray water mist from top to bottom in sequence for dust reduction, so as to further improve the dust reduction effect.

[0035] Preferably, the lifting mechanism 2 includes a screw rod 20 rotatably arranged on the pile body 1 and a driving source for driving the screw rod 20 to rotate, the screw rod 20 is screwed with a wire block 21, a column 22 is rotatably arranged on the wire block 21, the first nozzle 10 and the second nozzle 11 are integrated on the column 22; it also includes a position switching mechanism, which drives the column 22 to rotate to realize the position switching of the first nozzle 10 and the second nozzle 11.

[0036] Specifically, in the present embodiment, the lifting mechanism 2 is preferably a screw rod 20 transmission mechanism, that is, the driving source drives the screw rod 20 to rotate, and the wire block 21 is restricted by the pile body 1 and cannot follow the circumferential movement of the screw rod 20. The rotation of the screw rod 20 exerts a force on the wire block 21 through the thread, so that the wire block 21 can move along the axial direction of the screw rod 20. Therefore, the forward and reverse rotation of the screw rod 20 can drive the wire block 21 to move up and down, thereby realizing the injection height adjustment of the first nozzle 10.

[0037] In the above-mentioned embodiment, the second nozzle 11 can spray water to wash the road surface, and there are three spraying modes (spraying directions):

[0038] Among them, for the upward oblique spray and the downward oblique spray, if the water pressure increases from small to large, the second nozzle 11 can wash the road surface from near to far, but the problem with these two methods is that the water pressure of the tap water remains basically unchanged. If you want to change the water pressure, you need to add a booster pump, which will undoubtedly increase the cost.

[0039] In horizontal spraying, the water flow is ejected in a horizontal throwing state. If the second nozzle 11 is close to the road surface, then due to the obstruction of the road surface, the farther away from the second nozzle 11, the worse the spraying effect of the water flow is, so it is difficult to wash the road surface clean. If a booster pump is added, the cost will also increase.

[0040] Therefore, in this embodiment, a column 22 is rotatably set on the wire block 21, and the first nozzle 10 and the second nozzle 11 are concentrated on the column 22. Preferably, the angle between the first nozzle 10 and the second nozzle 11 is 90 degrees. After the first nozzle 10 is driven to spray water mist from top to bottom to reduce dust, the position switching mechanism switches the positions of the first nozzle 10 and the second nozzle 11, and then the second nozzle 11 is driven to move from bottom to top. During the movement, the second nozzle 11 sprays water to flush the road surface. During this process, no matter whether the second nozzle 11 is spraying obliquely upward, obliquely downward or horizontally, as the height increases, its spraying on the road surface is also carried out from near to far, and there is no need to add a booster pump, and it can be achieved by using the lifting mechanism 2.

[0041] Preferably, a shielding portion 12 is provided on the pile body 1, and the shielding portion 12 prevents dust from entering the interior of the pile body 1; specifically, there is a lot of dust on the road, and the dust entering the pile body 1 will affect the operation of the mechanism. Therefore, by providing the shielding portion 12, dust can be prevented from entering. The shielding portion 12 can be made of elastic cloth material to adapt to the position changes of the first nozzle 10 and the second nozzle 11.

[0042] In the above-mentioned embodiment, when the positions of the first nozzle 10 and the second nozzle 11 are switched, the nozzles that do not need to work should be prevented from entering with water. Therefore, a solenoid valve can be provided on each corresponding water pipe 13. When the positions of the first nozzle 10 and the second nozzle 11 are switched, the solenoid valve closes the water flow, and the corresponding nozzle will not spray water or water mist. This is an automatic way to cut off the water flow. The present invention also provides another passive way to switch the water flow, that is, the column 22 is eccentrically arranged on the rotating shaft 35 of the wire block 21. After the first nozzle 10 and the second nozzle 11 switch positions, the column 22 blocks the water flow from entering the second nozzle 11. After the positions of the second nozzle 11 and the first nozzle 10 switch positions, the column 22 blocks the water flow from entering the first nozzle 10.

[0043] Specifically, the column 22 does not use its own central axis as the rotation axis 35 line, but is eccentrically arranged on the rotation axis 35. Then, when the first nozzle 10 and the second nozzle 11 are switched in position, the column 22 is equivalent to swinging with the rotation axis 35. When the first nozzle 10 is working, the column 22 swings to one position, and when the second nozzle 11 swings, the column 22 swings to another position. The two positions are symmetrically arranged in a radial direction parallel to the horizontal with the rotation axis 35. Then, the column 22 and the wire block 21 can be used to clamp the water pipe 13 for supplying water to the first nozzle 10 or the water pipe 13 for supplying water to the second nozzle 11. In this way, while the column 22 is used to rotate and switch the position of the first nozzle 10 and the second nozzle 11, it is also possible to squeeze the water pipe 13 corresponding to the nozzle that does not need water supply, so that the water flow therein is cut off.

[0044] In the aforementioned embodiment, the position switching mechanism is used to switch the position of the first nozzle 10 and the second nozzle 11, which mainly drives the column 22 to rotate eccentrically on the wire block 21 to achieve the position switching of the first nozzle 10 and the second nozzle 11. Therefore, a driving source for driving the column 22 to rotate can be provided, such as a motor, and the output shaft of the motor is directly connected to the rotating shaft 35 of the column 22. This is an active switching method. In this embodiment, a passive position switching method of the first nozzle 10 and the second nozzle 11 is provided, namely:

[0045] The position switching mechanism includes two baffles 30 arranged at the upper and lower ends of the pile body 1, a slideway 31 is arranged on the wire block 21, a slide rod 32 is slidably arranged in the slideway 31, and a first elastic member is connected between the slide rod 32 and one end of the slideway 31 in the sliding direction, a first slide groove 33 is arranged on the first nozzle 10, and a second slide groove 34 is arranged on the second nozzle 11, and the proximal ends of the first slide groove 33 and the second slide groove 34 are both open ends; when the first nozzle 10 is operating, one end of the slide rod 32 is in the first slide groove 33, and during the downward movement of the wire block 21, the slide rod 32 is affected by the pile body 1, the blocking bar 30 at the lower end of the pile body 1 is blocked to push up the first nozzle 10 so that the first nozzle 10 and the second nozzle 11 switch positions, and one end of the slide rod 32 comes out from the open end of the first slide groove 33 and enters from the open end of the second slide groove 34; when the second nozzle 11 is working, one end of the slide rod 32 is in the second slide groove 34, and during the upward movement of the wire block 21, the slide rod 32 is blocked by the blocking bar 30 at the upper end of the pile body 1 to push up the first nozzle 10 so that the second nozzle 11 and the first nozzle 10 switch positions, and one end of the slide rod 32 comes out from the open end of the second slide groove 34 and enters from the open end of the first slide groove 33.

[0046] Specifically, according to the aforementioned embodiment, the switching between the first nozzle 10 and the second nozzle 11 is performed at the upper and lower ends of the pile body 1. Therefore, in the present embodiment, a switching space is respectively provided at the upper and lower ends of the pile body 1. Then, in the vertical direction of the pile body 1, it is divided into three areas, from bottom to top: switching space-injection space-switching space. The two baffles 30 are respectively arranged at the junction of the two switching spaces and the injection space. The position switching of the first nozzle 10 and the second nozzle 11 is achieved by the rotation of the column 22. It is necessary to give the column 22 a circumferential thrust to drive its rotation. In this way, the sliding trajectory of the slide rod 32 in the slideway 31 can be linear and parallel to a certain tangent in the rotation direction of the column 22. The sliding trajectory of the slide rod 32 in the slideway 31 can also be an arc. The center of the arc is on the central axis of the column 22. When the sliding rod 32 is blocked by a certain stop bar 30, the sliding rod 32 cannot move vertically with the movement of the wire block 21. That is, if the wire block 21 is used as a reference at this time, the sliding rod 32 is moving, and the proximal ends of the first slide groove 33 and the second slide groove 34 are both open ends. Now, taking the position switching of the first nozzle 10 and the second nozzle 11 as an example, that is, when the wire block 21 drives the first nozzle 10 to move downward, when the sliding rod 32 is in the stop bar 30 that touches the lower end of the pile body 1, one end of the sliding rod 32 is in the first slide groove 33 and abuts against the open end of the first slide groove 33. After the sliding rod 32 contacts the stop bar 30, the wire block 21 continues to move downward, and the downward movement of the sliding rod 32 is blocked, and one end of the sliding rod 32 abuts against the non-open end of the first slide groove 33. Then the sliding rod 32 will give a thrust to the non-open end of the first slide groove 33, so that the first nozzle 10 has a tendency to rotate clockwise (for ease of description and understanding, Figure 3As an example, taking the arrangement of the first nozzle 10 and the second nozzle 11 in the figure as an example, as the wire block 21 continues to move downward, the slide bar 32 will push the first nozzle 10 to rotate clockwise, so that the first nozzle 10 gradually changes from a horizontal state to a vertical state, and the second nozzle 11 gradually changes from a vertical state to a horizontal state, thereby realizing the switching of the positions of the first nozzle 10 and the second nozzle 11, and vice versa, the position switching of the second nozzle 11 and the first nozzle 10 is also the same, wherein one end of the slide bar 32 can enter and exit from the open end of the first slide groove 33, and can also enter and exit from the open end of the second slide groove 34, so that when the positions of the first nozzle 10 and the second nozzle 11 (the second nozzle 11 and the first nozzle 10) need to be switched, one end of the slide bar 32 can contact both the first slide groove 33 and the second slide groove 34.

[0047] Since one end of the slide bar 32 will enter the second slide slot 34 from the first slide slot 33 during the position switching between the first nozzle 10 and the second nozzle 11, it is necessary to limit the position after the first nozzle 10 and the second nozzle 11 are switched to avoid that the position of the column 22 is unstable when the water flow or water mist is subsequently sprayed. Therefore, a limiting mechanism is provided at the connection between the rotating shaft 35 of the column 22 and the wire block 21, that is, a round block 36 is fixedly connected to the rotating shaft 35, and a limiting block 37 is provided at each radial end of the round block 36 for sliding along the radial direction, and in the sliding direction, a fifth elastic member is connected between the limiting block 37 and the round block 36, and four limiting grooves 38 are sequentially provided on the wire block 21 in the circumferential direction of the rotating shaft 35. When the two limiting grooves 38 are When the positioning block 37 is in two radially opposite limiting grooves 38, the first nozzle 10 is in a working state; when the two limiting blocks 37 are in the other two radially opposite limiting grooves 38, the second nozzle 11 is in a working state; the portion between two adjacent limiting grooves 38 is in an arc shape and is closer to the center position of the rotating shaft 35 than the limiting grooves 38; then, when the limiting block 37 enters the adjacent limiting groove 38 from one limiting groove 38, it will first be squeezed into the round block 36, and the elastic force of the fifth elastic member will increase; then, under the action of the rebound force of the fifth elastic member, the limiting block 37 will extend out of the round block 36 again, that is, the elastic force of the fifth elastic member is used to limit the first nozzle 10 and the second nozzle 11 in the switching position.

[0048] Furthermore, a friction portion 14 is provided on the pile body 1, and the friction portion 14 is provided between two baffles 30, and the other end of the slide rod 32 is in contact with the friction portion 14 in a sliding friction manner; when the first nozzle 10 is driven to move downward, based on the friction between the slide rod 32 and the friction portion 14, the first nozzle 10 sprays water mist in an oblique upward form; when the second nozzle 11 is driven to move upward, based on the friction between the slide rod 32 and the friction portion 14, the second nozzle 11 sprays water in an oblique downward form.

[0049] Specifically, the friction portion 14 is a plate-like structure provided on the pile body 1, and is located in the injection space. The other end of the slide rod 32 contacts the friction portion 14 in a sliding friction manner. In the aforementioned embodiment, the limiting position after the position switching of the first nozzle 10 and the second nozzle 11 is mainly achieved by the elastic force of the fifth elastic member so that the limiting block 37 extends out of a part of the round block 36 and is plugged into the limiting groove 38, and the part between two adjacent limiting grooves 38 is in an arc shape and is closer to the center position of the rotating shaft 35 than the limiting groove 38. This means that when the slide rod 32 is subjected to the friction resistance, it can push the first nozzle 10 or the second nozzle 11 to deflect a certain amount. Angle, the deflection angle depends on the friction between the slide bar 32 and the friction part 14, so according to actual needs, the spraying mode of the first nozzle 10 can be changed to oblique upward throwing. At a specific oblique upward throwing angle, such as an elevation angle of 20 degrees, the spraying distance of the water mist is farther and the sprayed water mist falls in an arched structure, and its coverage height can exceed the height of the pile body 1, thereby better improving the air dust reduction effect, and the spraying mode of the second nozzle 11 is changed to oblique downward throwing. At a specific oblique downward throwing angle, such as an inclination angle of 20 degrees, the water flow can be sprayed from a position closer to the pile body 1, thereby better comprehensively flushing the road surface in the target area.

[0050] In the aforementioned embodiment, the first nozzle 10 is in an oblique upward throwing manner due to the friction between the slide bar 32 and the friction part 14 when spraying water mist, and the second nozzle 11 is in an oblique downward throwing manner due to the friction between the slide bar 32 and the friction part 14 when spraying water flow. In this case, there will be a problem that the column 22 and the wire block 21 cannot completely press the water pipes 13 corresponding to the first nozzle 10 and the second nozzle 11 respectively, that is, when the first nozzle 10 sprays water mist, water will flow out of the second nozzle 11, and vice versa when the second nozzle 11 sprays water flow, water will also flow out of the first nozzle 10.

[0051] Therefore, according to the above problem, in the present embodiment, further, when the positions of the first nozzle 10 and the second nozzle 11 are switched with each other, the column 22 has two positions: in the first position, the column 22 blocks the water flow from entering the second nozzle 11; the first top block 15 is slidably provided at the part of the wire block 21 corresponding to the first position, and in the sliding direction, a second elastic member is connected between the first top block 15 and the wire block 21, and under the elastic force of the second elastic member, there is a tendency for the first top block 15 and the column 22 to always be in contact with each other; in the second position, the column 22 blocks the water flow from entering the first nozzle 10; the second top block 16 is slidably provided at the part of the wire block 21 corresponding to the second position, and in the sliding direction, a third elastic member is connected between the second top block 16 and the wire block 21, and under the elastic force of the third elastic member, there is a tendency for the second top block 16 and the column 22 to always be in contact with each other.

[0052] Specifically, the first top block 15 and the second top block 16 are both adapted to the outer structure of the column 22. Under the elastic force of the second elastic member, the first top block 15 and the column 22 tend to always be in contact with each other. However, when the column 22 is in the first position, the distance between the column 22 and the first top block 15 is not enough to squeeze the water pipe 13 for supplying water to the first nozzle 10, but the distance between the column 22 and the second top block 16 is enough to squeeze the water pipe 13 for supplying water to the second nozzle 11. Conversely, when the column 22 is in the second position, the distance between the column 22 and the first top block 15 is enough to squeeze the water pipe 13 for supplying water to the first nozzle 10, but the distance between the column 22 and the second top block 16 is not enough to squeeze the water pipe 13 for supplying water to the second nozzle 11. Therefore, when the first nozzle 10 sprays water mist, the second nozzle 11 will not leak, and when the second nozzle 11 sprays water, the first nozzle 10 will not leak.

[0053] Furthermore, the friction part 14 is slidably arranged on the pile body 1, and in the sliding direction, a fourth elastic member is connected between the friction part 14 and the pile body 1, and an extrusion part 4 is provided on the pile body 1; in the downward movement of the wire block 21, the extrusion part 4 squeezes the upper end of the friction part 14, and the friction force between the other end of the sliding rod 32 and the friction part 14 gradually decreases, and the first nozzle 10 gradually tends to spray water mist from an oblique upward throwing situation to a horizontal situation.

[0054] Specifically, in the aforementioned embodiment, when the first nozzle 10 sprays water mist in an oblique upward manner, the distance between the column 22 and the wire block 21 is closer than when the first nozzle 10 sprays water mist horizontally, so the distance between the column 22 and the second top block 16 is also shortened, so that a certain amount of squeezing is produced on the water pipe 13 that supplies water to the first nozzle 10, and the water pressure of the first nozzle 10 spraying water mist in an oblique upward manner is increased, which can expand the dust reduction range at high altitudes. However, for air dust reduction, it is best to drop the dust in the air to the road surface in the target area for the second nozzle 11 The water jet is used for flushing. Therefore, during the downward movement of the first nozzle 10, its spraying range should gradually become smaller to concentrate the dust in the target area as much as possible and drop it on the road surface in the target area. That is, the extrusion part 4 squeezes one end of the friction part 14 so that the friction part 14 can be tilted. During the downward movement of the wire block 21, the friction between the slide bar 32 and the friction part 14 gradually decreases, and the distance between the column 22 and the second top block 16 becomes larger. The water pipe 13 supplying water to the first nozzle 10 is squeezed lighter and lighter, so that the first nozzle 10 can be changed from obliquely throwing water mist to horizontally spraying water mist.

[0055] Preferably, the extrusion portion 4 includes an extrusion block 40 slidably arranged on the pile body 1, and in the sliding direction, a sixth elastic member is connected between the extrusion block 40 and the pile body 1, the extrusion block 40 is arranged at the upper end of the friction portion 14, and a plate body 41 is connected to the extrusion block 40; when the column 22 enters the first position from the second position, the first top block 15 is driven by the extrusion action of the column 22 to drive the plate body 41 to move downward.

[0056] Specifically, during the stroke of the column 22 entering the first position from the second position, the distance between the column 22 and the first top block 15 is gradually shortened, that is, the column 22 exerts an extrusion effect on the first top block 15, and the first top block 15 moves on the wire block 21 in a direction away from the center line of the rotating shaft 35, and the first top block 15 exerts a downward extrusion effect on the plate body 41. For example, wedge-shaped surfaces are provided on the first top block 15 and the plate body 41, and when the two wedge-shaped surfaces contact, mutual extrusion is generated, so that the plate body 41 drives the extrusion block 40 connected thereto to move downward, and the downward movement of the extrusion block 40 exerts an extrusion effect on the upper end of the friction portion 14. Since a fourth elastic member is connected between the friction portion 14 and the pile body 1, the friction portion 14 can be seen to be floating, so that when an external force is applied to a certain point thereof, deflection may occur, thereby achieving the purpose of gradually reducing the friction between the slide bar 32 and the friction portion 14 from top to bottom.

[0057] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the protection of the present invention.
