Description

Technical Field

[0001] The invention relates to the technical field of foundation pit anti-fall warning, and in particular to a foundation pit anti-fall warning device. Background Art

[0002] Foundation pit engineering is an important part of civil engineering. Foundation pit refers to the deep pit dug during construction for the construction of underground facilities.

[0003] There are often safety hazards in the use of foundation pits. Small animals, pedestrians and vehicles may accidentally fall into them, causing casualties or property losses. In order to avoid dangerous behaviors, an inflatable device is directly placed in the foundation pit and filled with air to form a physical barrier, which fundamentally reduces the risk of falling and curbs the occurrence of falling accidents.

[0004] For foundation pits of different depths, workers use inflatable devices to directly increase the height by stacking to fill the entire foundation pit. However, as the number of inflatable devices increases, there is a lack of effective fixing structure between adjacent inflatable devices, which causes the center of gravity of the overall structure of the inflatable device to rise, thereby weakening the stability of the overall structure. Under the influence of external factors, the inflatable device will undergo relative displacement or tilt, which not only affects the safety of the foundation pit project, but also reduces the effectiveness of the inflatable device as a fall prevention warning. Summary of the invention

[0005] In view of the problem that the existing foundation pit anti-fall warning device has an increase in the number of inflatable devices, which causes the center of gravity to move upward, reduces stability, and is easy to shift or tilt under external force, causing structural imbalance, the present invention is proposed.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0041] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0042] Example 1, reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a foundation pit 102 anti-fall warning device, the device comprising:

[0043] The foundation pit unit 100 includes a soil layer 101 and a foundation pit 102 disposed on the soil layer 101; and

[0044] The filling unit 200 includes a filling piece 1 201, a filling piece 202, a connecting assembly 203, a trigger assembly 204 and a snap-on assembly 205, wherein the filling piece 1 201 is arranged at the lower end of the foundation pit 102, the filling piece 202 is arranged at the upper end of the foundation pit 102, the connecting assembly 203 is arranged between the top of the filling piece 1 201 and the bottom of the filling piece 202, the trigger assembly 204 is arranged on the filling piece 202, and the snap-on assembly 205 is arranged on the connecting assembly 203. Filler piece 1 201 and filler piece 202 are an illustrative object in this embodiment. There are two or even several fillers in a foundation pit 102. The foundation pit 102 on the soil layer 101 is filled to remind pedestrians and vehicles. Each two adjacent fillers need to be connected using a connecting component 203 and fixed using a snap-on component 205. The connecting component 203 is arranged between filler piece 1 201 and filler piece 202. Through the connecting component 203 and the snap-on component 205, the various fillers in the filling unit 200 can be tightly fixed, thereby avoiding the problem of overall structural instability caused by height increase.

[0045] The connection assembly 203 includes a connection pipe 203a, a sleeve 1 203b, a sleeve 203c and a connection column 203d, wherein the connection pipe 203a is arranged on the filling piece 202, the sleeve 1 203b is arranged on the connection pipe 203a, the sleeve 203c is arranged on one side of the sleeve 1 203b, and the connection column 203d is arranged on the sleeve 2 203c. One end of the connection column 203d is arranged on the filling piece 1 201. The connecting pipe 203a is used to fix the sleeve 1 203b on the filling piece 202, and the connecting column 203d is used to fix the sleeve 203c on the filling piece 1 201. The entire connecting assembly 203 is used to connect two adjacent filling pieces 1 201 and filling pieces 2 202, thereby increasing the stability of the connection between the filling piece 202 accumulated on the filling piece 1 201 and the filling piece 1 201 during use, and preventing the filling piece 202 from being displaced on the filling piece 1 201, which would cause a decrease in the stability of the filling piece 202 at the upper end of the foundation pit 102. Casing 1 203b and casing 2 203c are separable. Before placing filling piece 1 201 and filling piece 202 into the foundation pit 102, the operator can pre-connect casing 1 203b and casing 2 203c, fill filling piece 1 201 with gas, install casing 1 203b on casing 2 203c, and then inflate filling piece 202 and finally place it in the foundation pit 102.

[0046] The clamping assembly 205 includes a limiting groove 205a, a magnetic sheet 1 205b and a support member 205c, wherein the limiting groove 205a is arranged on the sleeve 1 203b, the magnetic sheet 1 205b is arranged on the top of the limiting groove 205a, and the support member 205c is arranged in the sleeve 1 203b. The diameter of the sleeve 203c is equal to the diameter of the sleeve 1 203b, and the diameter of the support tube 205c-1 in the support member 205c is smaller than the diameter of the sleeve 1 203b, so that the support tube 205c-1 can slide in the limiting groove 205a in the sleeve 1 203b.

[0047] Among them, the card assembly 205 also includes a card slot 205d, a slide groove 205e, a slider 205f and a magnetic piece 205g, wherein the card slot 205d is arranged on the sleeve 1 203b, the slide groove 205e is arranged on the sleeve 203c, the slider 205f is arranged in the slide groove 205e, and the magnetic piece 205g is arranged on the support member 205c. The sliding groove 205e and the slider 205f on the second sleeve 203c are used to fix the support tube 205c-1 to slide in the second sleeve 203c. The mutual attraction between the magnetic sheet 1 205b and the magnetic sheet 1 205b can drive the support tube 205c-1 to slide in the limiting groove 205a, thereby forming a "sleeve" design between the sleeve 1 203b and the second sleeve 203c, which can enable the filling piece 202 to be quickly positioned on the filling piece 1 201, thereby increasing the stability of the filling piece 1 201 and the filling piece 202 during use.

[0048] During use, the operator first measures the foundation pit 102 to determine the number and size of the required filling pieces. Then, after the filling piece 1 201 is filled with gas, the operator will pre-connect the sleeve 1 203b and the sleeve 2 203c. Connecting the sleeve 1 203b and the sleeve 2 203c in advance can reduce the time and complexity of on-site operations and improve installation efficiency. In this way, before the filling piece is placed in the foundation pit 102, it can ensure that the connection between the filling piece 1 201 and the filling piece 2 202 is stable. The support tube 205c-1 in the support piece 205c is set in the sleeve 1 203b. Since the caliber of the support tube 205c-1 is smaller than that of the sleeve 1 203b, it can slide freely in the limit groove 205a. On the sleeve 1 203b and the support tube 205c-1, the magnetic sheet 205g interacts with the magnetic sheet 1 205b to generate attraction, which helps the support tube 205c-1 slide in the limit groove 205a, thereby realizing the tight connection between the sleeve 1 203b and the sleeve 2 203c. The magnetic attraction of the magnetic sheet 1 205b and the magnetic sheet 205g can quickly and accurately position the sleeve, thereby improving the stability and reliability of the connection. Subsequently, the operator will inflate the filler 202 until the required volume and pressure are reached, and then place it in the foundation pit 102 to ensure that the filler 202 is correctly located at the upper end of the foundation pit 102. Correctly inflating and positioning the filler in the foundation pit 102 can ensure that the foundation pit 102 is effectively filled, while reminding pedestrians and vehicles to pay attention to safety. Through the synergistic effect of the connecting component 203 and the clamping component 205, the fixing effect between adjacent fillers is enhanced, and the structural instability caused by the height increase is prevented. It can ensure that the filling piece 1 201 and the filling piece 202 in the anti-fall warning device of the foundation pit 102 are installed quickly and safely.

[0049] Through the connection assembly 203 and the clamping assembly 205, each filling piece in the filling unit 200 can be tightly fixed, thereby avoiding the problem of overall structural instability caused by height increase. Not only does it significantly enhance the protection safety of the foundation pit 102, but it also ensures the stability and reliability of the warning device on the filling piece under various environmental conditions.

[0050] Example 2, reference Figure 1-Figure 9, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the trigger assembly 204 includes a gas delivery member 204a arranged in the connecting tube 203a, a gas pipe 204b arranged at one end of the gas delivery member 204a, a gas delivery hole 204d arranged at the other end of the gas delivery member 204a, and an air bag 204c arranged on the air pipe 204b; the gas delivery member 204a is arranged on the second filling member 202. During the inflation process of the second filling member 202, the gas in the second filling member 202 will enter the air bag 204c from the gas pipe 204b along the gas delivery hole 204d, and the expansion of the air bag 204c will squeeze the extrusion block, thereby driving the clamping block 205c-5 to slide in the guide and be clamped in the clamping groove 205d on the sleeve 1 203b, so that the support tube 205c-1 is positioned on the sleeve 1 203b, and then the sleeve 1 203b and the sleeve 2 203c are connected. Since the aperture of the gas delivery hole 204d is relatively small, the gas in the second filling member 202 enters the airbag 204c. After the airbag 204c expands, the gas in the airbag 204c and the gas in the second filling member 202 are kept in balance.

[0051] Compared with Example 1, further, the support member 205c includes a support tube 205c-1 arranged on the slider 205f, a guide groove 205c-2 arranged on the support tube 205c-1, a guide column 205c-4 arranged on the guide groove 205c-2, and a spring 205c-3 arranged on the guide column 205c-4.

[0052] The support member 205c further includes a block 205c-5 disposed on the guide groove 205c-2 and matching the card slot 205d, a squeeze plate 205c-6 disposed on the block 205c-5, and an arc groove 205c-7 disposed on the squeeze plate 205c-6. The arc groove 205c-7 is used to match the arc surface of the airbag 204c. The expansion of the airbag 204c pressurizes the squeeze plate 205c-6. When the gas in the airbag 204c is released, the block 205c-5 is separated from the card slot 205d under the action of the guide column 205c-4 and the spring 205c-3, so that the installation, fixing and removal of the sleeve 1 203b and the sleeve 2 203c are realized.

[0053] During use, the operator first ensures that the trigger assembly 204 is correctly installed on the filling piece 202. When the filling piece 202 is inflated, the gas will flow into the air pipe 204b through the gas delivery hole 204d, and finally enter the airbag 204c, so that the airbag 204c expands. As the airbag 204c expands, the automatic expansion and contraction mechanism of the airbag 204c reduces the need for manual operation, improves the efficiency and accuracy of the connection, and the airbag 204c applies pressure to the extrusion plate 205c-6, pushing the block 205c-5 to slide along the guide groove 205c-2 on the guide column 205c-4, and finally snap into the slot 205d of the sleeve 1 203b, thereby achieving the connection between the sleeve 1 203b and the sleeve 2 203c. In this process, due to the small aperture of the gas delivery hole 204d, the gas pressure in the airbag 204c is balanced with the gas pressure in the filling member 202. The pressure balance of the airbag 204c and the automatic positioning of the block 205c-5 ensure that the connection between the sleeves is more stable, prevent accidental falling off, and ensure the stability of the connection. The support tube 205c-1, the guide groove 205c-2, the guide column 205c-4 and the spring 205c-3 work together to fix the block 205c-5 when the airbag 204c is expanded, and when the gas in the airbag 204c is released, the block 205c-5 can be smoothly separated from the groove 205d through the elastic force of the guide column 205c-4 and the spring 205c-3. Not only does it simplify the installation and removal process of the sleeve 1 203b and the sleeve 2 203c, but it also improves the safety and convenience of operation.

[0054] The remaining structures are the same as those of Example 1.

[0055] Example 3, reference Figure 1-Figure 12 , which is the third embodiment of the present invention, and which is different from the second embodiment in that: it also includes,

[0056] The auxiliary unit 300 includes an auxiliary base 301 disposed on the top and bottom of the filler 1 201, a warning component 302 disposed on the auxiliary base 301 on the top of the filler 1 201, and a protection component 303 disposed on the auxiliary base 301 on the top of the filler 1 201; the auxiliary base 301 disposed on the top and bottom of the filler 2 202 is the same as the auxiliary base 301 disposed on the filler 1 201. The visible transparent protection shell 303b in the protection component 303 is installed on the auxiliary base 301, providing physical protection for the warning light 302b and other electronic components inside to prevent damage caused by environmental factors such as dust, moisture, impact, etc.

[0057] The warning light 302b in the warning component 302 is used to improve the visibility of the foundation pit 102. By emitting bright light or flashing signals, it reminds pedestrians and vehicles of the existence of the foundation pit 102, thereby avoiding accidental falls.

[0058] Compared with Example 2, further, the warning component 302 includes a photovoltaic panel 302a disposed on the top auxiliary base 301, and a warning light 302b disposed on the top auxiliary base 301; the warning light 302b is disposed on one side of the photovoltaic panel 302a; the photovoltaic panel 302a in the warning component 302 can convert solar energy into electrical energy, providing a continuous power supply for the warning light 302b, reducing dependence on an external power source, and also reducing energy consumption

[0059] The protection component 303 includes a thread 303a disposed on the auxiliary base 301, and a protection shell 303b disposed on the thread 303a; the protection shell 303b is visible and transparent. The visible and transparent property of the protection shell 303b allows the light of the warning light 302b to penetrate, which protects the internal components without affecting the visibility and warning effect of the warning light 302b.

[0060] Among them, the top auxiliary base 301 is provided with an inflatable member 304, the top auxiliary base 301 is provided with a hair-like member 305, and the bottom auxiliary base 301 is provided with a hook-like member 306. The plane of the filler 1 201 is a hexagon, and the arc value of the inner angle formed between each two adjacent sides of the hexagon is α. The design of the hair-like member 305 and the hook-like member 306 increases the stability between the top of the filler 1 201 and the bottom of the filler 2 202. When the protective shell 303b on the top of the filler 1 201 and the bottom of the filler 2 202 is removed, the hair-like member 305 and the hook-like member 306 cooperate with the connecting component 203 and the clamping component 205 to help fix the filler 1 201 and the filler 2 202 to prevent sliding. The design of the hexagonal internal angle radian value α, on the one hand, enables filler 1 201 and filler 2 202 to adapt to various foundation pits 102, and on the other hand, helps to evenly disperse the pressure on the surface of filler 1 201 and filler 2 202, reduce local stress concentration, and improve the structural strength and durability of filler 1 201 and filler 2 202.

[0061] During use, the auxiliary base 301 provides a stable installation platform for the warning component 302 and the protection component 303. The visible transparent protective shell 303b in the protection component 303 is installed on the auxiliary base 301, which not only protects the internal warning light 302b and other electronic components from damage by environmental factors such as dust, moisture and impact, but also allows the light of the warning light 302b to penetrate, ensuring that the warning effect is not affected. The warning light 302b in the warning component 302 significantly improves the visibility of the foundation pit 102 by emitting bright light or flashing signals, effectively reminding pedestrians and vehicles of the existence of the foundation pit 102, thereby preventing accidental falls. The inflatable member 304 on the top auxiliary base 301 can be inflated when needed to increase the volume and weight of the filling member, thereby improving the stability of the device. The hair-like member 305 and the hook-like member 306 provide additional fixing methods to further enhance the stability between the filling member 1 201 and the filling member 2 202.

[0062] The hexagonal design of the filler 1 201 and the filler 2 202 has an arc value of α between each two adjacent sides. Such a geometric shape not only optimizes the space utilization, so that the filler can more effectively fill the foundation pit 102 space, but also helps to evenly disperse the pressure on the surface of the filler, reduce local stress concentration, and improve the structural strength and durability of the filler. It can adapt to various foundation pits 102, regardless of shape or size, and can provide effective anti-fall warning and protection.

[0063] The diameter of the hexagonal cross section of the filling piece 1 201 and the filling piece 202 is 40 to 60 centimeters, and the height of the filling piece 1 201 and the filling piece 202 is adjustable to 1.5 meters, 1.7 meters, 2 meters, and 3 meters. When the foundation pit 102 is more than 3 meters deep and the diameter is greater than 60 centimeters, multiple filling devices can be attached together to meet various pit depth and pit width requirements. The filling piece 1 201 and the filling piece 202 are made of high-density polyethylene (HDPE), which is light, strong, airtight, and has strong pressure-bearing capacity.

[0064] The remaining structure is the same as that of Example 2.
