Description

Technical Field

[0001] The invention belongs to the technical field of construction fencing, and specifically refers to an easy-to-fix building construction edge safety protection device. Background Art

[0002] The perimeter of construction sites is often surrounded by fences. On the one hand, it can clearly demarcate the construction area and non-construction area. On the other hand, the fences can also ensure safety and prevent dust leakage to a certain extent. Fences are mainly divided into two categories: metal fences and hollow plastic fences. Hollow plastic fences are often used in various short-term and temporary construction sites because they are more convenient and flexible to install.

[0003] This type of enclosure is light in weight and easy to transport and carry. It is usually fixed in place by injecting water into the base, causing little damage to surrounding facilities. However, traditional enclosures are distributed independently of each other, especially the water injection process, which needs to be performed one by one. Not only is the operation cumbersome, but it is also difficult to ensure a uniform amount of water injected. If the amount of water injected is too little, the stability of the enclosure itself will be affected. If the amount of water injected is too much, there may be an embarrassing problem of insufficient water carried.

[0004] In fact, there are already some technical solutions that connect each enclosure through a joint, so that by injecting water at one end, the height of the liquid level inside the enclosure can be kept consistent; however, this solution can only be used in scenarios where the ground is well level (the altitude liquid level must be consistent to make the amount of liquid inside each enclosure the same), and if one enclosure leaks, the water in all enclosures will be lost. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a safety protection device for the edge of a construction site that is easy to fix and can be interconnected during water injection and can automatically change to an independent state after the water injection is completed; in order to ensure the uniformity of the water injection amount in each hollow isolation fence, the present invention creatively proposes a telescopic lever assembly, which can sense the liquid level height in the hollow isolation fence through a float. When the liquid level height rises to a certain level, it can automatically change the variable flow channel water pipe mechanism from an axially closed and radially connected state to an axially connected and radially closed state; thereby overcoming the technical contradiction that adjacent hollow isolation fences must be interconnected (to facilitate the completion of all water injection at one time) but cannot be interconnected (to avoid water leakage in one enclosure and the loss of all water in all enclosures).

[0006] Not only that, the height of the U-shaped lifting bracket can be actively adjusted and controlled through the manual rotating shaft. On the one hand, the water injection depth in the hollow isolation fence can be actively set by changing the pre-compression amount of the buoyancy counteracting spring. On the other hand, when you want to recover the liquid in the hollow isolation fence, you can actively control the rotation and opening and closing of the rotary valve core.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0042] like Figure 1 to Figure 11 As shown, the present invention proposes an easy-to-fix construction edge safety protection device, including a variable flow channel water pipe mechanism 1, an adaptive toggle mechanism 2 and a hollow fence assembly 3, the variable flow channel water pipe mechanism 1 is arranged in the hollow fence assembly 3, and the adaptive toggle mechanism 2 is arranged inside the hollow fence assembly 3.

[0043] The hollow fence assembly 3 includes a hollow isolation fence 42, a drain valve 43 and a quick connector 44. The water inlet pipe 6 and the water flow pipe 7 are respectively fixed to the two ends of the hollow isolation fence 42. The adjustment base 24 is fixed to the inner wall of one side of the hollow isolation fence 42. The drain valve 43 is arranged on the other side of the hollow isolation fence 42. The quick connector 44 is used for connecting the water inlet pipe 6 and the water flow pipe 7.

[0044] The adaptive toggle mechanism 2 includes an active adjustment component 21, a sliding lifting component 22 and a telescopic lever 36 component. The active adjustment component 21 is arranged inside the hollow fence component 3, the sliding lifting component 22 is arranged on the active adjustment component 21, and the telescopic lever 36 component is arranged on the sliding lifting component 22.

[0045] The adaptive toggle mechanism 2 can, on the one hand, automatically realize the rotation control of the rotary reversing component 5 when the liquid level in the hollow isolation fence 42 rises, and on the other hand, can actively control the rotation control of the rotary valve core 9 when the manual shaft 26 is actively rotated.

[0046] The active adjustment component 21 includes an adjustment base 24, an adjustment screw 25, a manual rotating shaft 26, an active bevel gear 27 and a driven bevel gear 28. The adjustment base 24 is arranged in the hollow fence component 3. The adjustment base 24 is symmetrically provided with guide slide rods 38. The adjustment screw 25 is rotatably arranged in the adjustment base 24. The manual rotating shaft 26 is rotatably arranged in the adjustment base 24. The adjustment screw 25 and the manual rotating shaft 26 are vertically distributed. The active bevel gear 27 is fixedly connected to the manual rotating shaft 26. The driven bevel gear 28 is fixedly connected to the adjustment screw 25. The active bevel gear 27 and the driven bevel gear 28 are meshed for transmission.

[0047] The sliding lifting assembly 22 includes a U-shaped lifting bracket 29, a lifting sleeve 30, a lifting nut 31 and a lifting slider 32. The lifting sleeve 30 is fixedly connected to the U-shaped lifting bracket 29. The lifting sleeve 30 is slidably arranged on the guide slide rod 38. The lifting nut 31 is fixedly connected to the U-shaped lifting bracket 29. The lifting nut 31 and the adjusting screw 25 are threadedly transmitted. There is a self-locking phenomenon between the lifting nut 31 and the adjusting screw 25, that is, when the adjusting screw 25 rotates, the lifting nut 31 can be driven to rise and fall, but the lifting and falling of the lifting nut 31 cannot drive the adjusting screw 25 to rotate.

[0048] The longitudinal height of the U-shaped lifting bracket 29 can be actively adjusted by rotating the manual rotating shaft 26. Not only can the active control of the rotation of the rotating valve core 9 be achieved through the active push of the lifting slide 33 by the U-shaped lifting bracket 29, but the liquid level when the telescopic lever 36 pushes the bracket 10 can also be changed by presetting the height of the U-shaped lifting bracket 29, thereby actively adjusting and presetting the liquid filling height in the hollow isolation fence 42.

[0049] A lifting rail 39 is provided on the U-shaped lifting bracket 29, and a lifting slider 32 is slidably engaged on the lifting rail 39. The telescopic lever 36 assembly includes a lifting slide plate 33 and a buoyancy antagonizing spring 34. The lifting slide plate 33 is fixedly connected to the lifting slider 32, and the buoyancy antagonizing spring 34 is provided between the lifting slide plate 33 and the U-shaped lifting bracket 29.

[0050] The telescopic lever 36 assembly also includes a float 35, a telescopic lever 36 and an extension return spring 37. The float 35 is provided with a support rod 40, and the float 35 is fixedly connected to the lifting slide 33 through the support rod 40. The telescopic lever 36 is provided with a telescopic slide rod 41, and the telescopic lever 36 is slidably engaged with the lifting slide 33 through the telescopic slide rod 41. The extension return spring 37 is arranged between the telescopic lever 36 and the lifting slide 33.

[0051] The variable flow channel water pipe mechanism 1 includes a fixed water pipe assembly 4 and a rotating reversing assembly 5. The fixed water pipe assembly 4 is arranged in the hollow fence assembly 3, and the rotating reversing assembly 5 is rotatably arranged on the fixed water pipe assembly 4.

[0052] By rotating the rotary reversing component 5, the flow direction of the liquid can be switched, so that the filling of the next hollow isolation fence 42 will not start until the filling of one hollow isolation fence 42 is almost completed, and after the filling is completed, the flow channel between the fixed water pipe component 4 and the hollow isolation fence 42 can be completely closed by rotating the rotary valve core 9 to isolate the liquid in the hollow isolation fence 42.

[0053] The fixed water pipe assembly 4 includes a water inlet pipe 6, a water flow pipe 7 and a fastening nut 8. The water inlet pipe 6 and the water flow pipe 7 are fixedly connected to the hollow fence assembly 3. The end of the water inlet pipe 6 is provided with a hollow portion 12, and the center position of the end of the water inlet pipe 6 is provided with a screw portion 13. The end of the water flow pipe 7 is provided with a central circular hole 15, and the screw portion 13 passes through the central circular hole 15. The fastening nut 8 and the screw portion 13 are threadedly connected. The water flow pipe 7 is provided with an arc flow channel 14, and one end of the arc flow channel 14 is provided with the water inlet pipe 6.

[0054] By controlling the overlapping area of ​​the arc flow channel 2 18 and the arc flow channel 1 14, not only the opening and closing of the axial flow channel can be controlled, but also the arc flow channel 2 18 can limit the circular convex shaft 16 so that the rotary valve core 9 can only rotate within a specific angle range, thereby ensuring the lifting and lowering of the telescopic lever 36 and controlling the bidirectional rotation of the rotary valve core 9.

[0055] The rotary reversing assembly 5 includes a rotary valve core 9 and a toggle bracket 10. The rotary valve core 9 is rotatably arranged between the water inlet pipe 6 and the water passage 7. The water inlet pipe 6 is provided with a water inlet notch 11. The rotary valve core 9 is provided with a valve core notch 17 matching the water inlet notch 11. The central disc of the rotary valve core 9 is provided with an arc flow channel 2 18 matching the arc flow channel 1 14. The central disc of the rotary valve core 9 is also provided with a central circular hole 2 19, and the screw portion 13 passes through the central circular hole 2 19. The toggle bracket 10 is provided with a mounting sleeve 20, and the toggle bracket 10 is fixedly connected to the outside of the rotary valve core 9 through the mounting sleeve 20.

[0056] During specific use, the user first needs to connect multiple devices in series to form a safety protection enclosure with a certain length. The adjacent water inlet pipe 6 and water pipe 7 are connected by a quick connector 44. The connected quick connector 44 can allow the liquid to flow freely. In the initial state, the variable flow channel water pipe mechanism 1 is in an axially closed and radially through state, that is, the water inlet gap 11 and the valve core gap 17 overlap, the arc flow channel 1 14 and the arc flow channel 2 18 do not overlap, and the telescopic lever 36 is located below the lever bracket 10.

[0057] After installation is completed, liquid is injected into the water inlet pipe 6 through an external water pump to improve the stability of the hollow isolation fence 42. In the initial state, since the water inlet gap 11 and the valve core gap 17 overlap, the arc flow channel 1 14 and the arc flow channel 2 18 do not overlap, so the liquid cannot flow to the water pipe 7 and the next hollow isolation fence 42, but will enter the hollow isolation fence 42 through the water inlet gap 11 and the valve core gap 17;

[0058] As the liquid level in the hollow isolation fence 42 gradually rises, when the liquid level exceeds the float 35, the float 35 will slowly rise under the action of buoyancy. At this time, since the U-shaped lifting bracket 29 is fixed, the buoyancy of the float 35 mainly resists the elastic force of the buoyancy counteracting spring 34, and the combined force of the two determines the sliding direction of the lifting slide 33.

[0059] As the buoyancy continues to increase, the lifting slide 33 will eventually rise with the telescopic lever 36, and the telescopic lever 36 will push the toggle bracket 10 to push the rotary valve core 9 and the toggle bracket 10 to rotate together;

[0060] During the rotation of the rotary valve core 9, there will be a stage where the water inlet gap 11 and the valve core gap 17 partially overlap, and the arc flow channel 1 14 and the arc flow channel 2 18 also partially overlap. At this time, the water supply pressure of the external water pump is relatively large. Even if the water supply pressure of the water pump passes through the partial pressure of the arc flow channel 14 and the arc flow channel 2 18, it is still sufficient to overcome the existing water pressure inside the hollow isolation fence 42. Therefore, the liquid in the hollow isolation fence 42 will not flow back into the water inlet pipe 6; in this stage, the liquid can continue to flow toward the hollow isolation fence 42, and can also flow into the next hollow isolation fence 42.

[0061] When the liquid level in the hollow isolation fence 42 continues to rise to a certain level, the circular convex shaft 16 slides from one end of the arc flow channel 2 18 to the other end, and the rotating valve core 9 rotates from the extreme position in one direction to the extreme position in the other direction; then the telescopic lever 36 will bypass the toggle bracket 10 that can no longer rotate through its own telescopic avoidance, and transfer itself from the bottom of the toggle bracket 10 to the top of the toggle bracket 10; at this time, the water inlet gap 11 and the valve core gap 17 no longer have any overlapping parts, and the arc flow channel 1 14 and the arc flow channel 2 18 completely overlap, that is to say, the liquid in the water inlet pipe 6 will only enter the next water inlet pipe 6 through the water pipe 7, and will not exchange liquid with the hollow isolation fence 42 where it is located.

[0062] Through the above process, liquid can be added to each hollow isolation fence 42 in turn, and after the liquid filling in one hollow isolation fence 42 is completed, the rotary valve core 9 can automatically rotate to close itself and fill the next hollow isolation fence 42 with liquid.

[0063] Since the hollow isolation fence 42 that has been filled with water is completely isolated from the fixed water pipe assembly 4, if a hollow isolation fence 42 is damaged and leaks during use, it will not affect other hollow isolation fences 42. At this time, although the float 35 will drop after picking up the buoyancy, the float 35's own gravity is far from enough to push the toggle bracket 10 downward, so the variable flow channel water pipe mechanism 1 will still remain in an axially penetrated and radially closed state.

[0064] When you want to actively recycle the hollow isolation fence 42, you need to first remove the liquid inside it:

[0065] Method 1: By opening the drain valve 43 , the liquid in the hollow isolation fence 42 can be discharged.

[0066] Method 2: If you want to recover the liquid in the hollow isolation fence 42, you only need to manually rotate the manual shaft 26, and the meshing transmission between the active bevel gear 27 and the driven bevel gear 28 can drive the adjusting screw 25 to rotate. The adjusting screw 25 can adjust the longitudinal position of the U-shaped lifting bracket 29 when rotating. At this time, the U-shaped lifting bracket 29 and the buoyancy counteract the downward pressure of the spring 34, and the telescopic lever 36 can push the lever 10 down, thereby driving the rotary valve core 9 to rotate;

[0067] The order of liquid recovery is opposite to the order of liquid injection, starting from a hollow isolation fence 42 farthest from the water pump. After the water in the hollow isolation fence 42 is completely pumped out by the water pump, the rotary valve core 9 is controlled to rotate by rotating the manual shaft 26 to recover the liquid in the previous hollow isolation fence 42.

[0068] When you want to change the water injection depth in the hollow isolation fence 42, you need to actively rotate the manual shaft 26 and set the height of the U-shaped lifting bracket 29 before injecting water, so as to adjust the initial compression amplitude of the buoyancy antagonism spring 34 and the elastic force that the buoyancy antagonism spring 34 can generate at the same liquid level depth, thereby changing the liquid level height in the hollow isolation fence 42 when the rotating valve core 9 is turned.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0070] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
