[0019] It should also be understood that any component, data or structure mentioned in the embodiments of this utility model can generally be understood as one or more unless explicitly defined or given contrary instructions in the context.

[0020] Furthermore, in this utility model, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this utility model, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0021] It should also be understood that the description of the various embodiments of this utility model emphasizes the differences between the various embodiments, and the similarities or similarities can be referred to each other. For the sake of brevity, they will not be described in detail.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0025] Figure 1 This is a schematic diagram showing the installation of the anti-fall warning device in the well shaft in some embodiments of this utility model. Figure 2 This is a partial schematic diagram illustrating a method for fixing the main rod in a shaft, as shown in one example of this utility model. Figure 1 and Figure 2 As shown, the rainwater and sewage well anti-fall warning device includes: Vertical pole; A warning device installed at the top of the vertical pole; The float 1 is sealed to the bottom of the vertical rod, wherein the float 1 can be a low-cost and easy-to-float foam float; A limiting device 2 is fitted outside the vertical rod and fixed to the well ladder 10, wherein the well includes a rainwater well or a sewage well; the cross-sectional area of ​​the limiting device 2 in the horizontal direction is smaller than the horizontal cross-sectional area of ​​the float 1 in the horizontal direction.

[0026] When the overall height of the rainwater / sewage well anti-fall warning device of this utility model matches the well depth of the rainwater / sewage well (the overall height is slightly less than the well depth), the float 1 can be immersed in the water surface at the bottom of the rainwater / sewage well.

[0027] When the manhole cover 11 of the rainwater well / sewage well is missing, and when the water level in the well increases due to the accumulation of water in the well, the float 1 causes the rainwater well / sewage well anti-fall warning device to move upward as a whole, so that the warning device can extend out of the well opening of the rainwater well / sewage well, thereby warning pedestrians or vehicles in the surrounding area.

[0028] As the float 1 moves the stormwater / sewage well anti-fall warning device upwards, the horizontal cross-sectional area of ​​the limiting device 2 is smaller than that of the float 1. Therefore, the height of the float 1 cannot exceed the installation height of the limiting device 2, thus ensuring that the stormwater / sewage well anti-fall warning device will not flow out of the stormwater / sewage well. The limiting device 2 not only limits the height of the stormwater / sewage well anti-fall warning device but also restricts the horizontal range of motion of the vertical rod.

[0029] In some embodiments of this utility model, the limiting device 2 is a fixed retaining ring, which can be engaged with a certain step of the ladder inside the rainwater well / sewage well, thereby realizing flexible limiting of the height of the rainwater and sewage well anti-fall warning device.

[0030] Furthermore, the limiting device 2 may include: a first retaining ring (i.e., a retaining ring that is fixed to the first ladder of the shaft) Figure 1 The middle retaining ring near warning flag 8), and the second retaining ring that secures the second ladder in the shaft (i.e. Figure 1 (Fixed ring number 2). Since the cross-sectional area of ​​the first fixed ring in the horizontal direction is smaller than that of the warning device in the horizontal direction, it can limit the downward movement of the rainwater / sewage well anti-fall warning device into the well. This prevents the entire rainwater / sewage well anti-fall warning device from falling below the second fixed ring 2 when the well is deep and contains little water. Furthermore, it prevents the warning device from failing to reach the well opening in time when there is a lot of water in the well and the well cover 11 is missing, or from flowing out of the well opening, thus ensuring the warning effect of the rainwater / sewage well anti-fall warning device.

[0031] In some embodiments of this utility model, the vertical pole includes a mother pole 3 and a daughter pole 4. The mother pole 3 is connected to the warning device, and the daughter pole 4 is connected to the float 1. The mother pole 3 and the daughter pole 4 are connected by a telescopic adjustment buckle 5, thereby enabling the overall height of the vertical pole to be adjustable. Workers can adjust the overall height of the vertical pole according to the depth of the rainwater well / sewage well and the water level in the rainwater well / sewage well.

[0032] In some embodiments of this utility model, the warning device includes a warning light 6, a battery 7 is installed inside the float 1, and a channel for connecting the warning light 6 and the battery 7 is provided inside the vertical rod. The battery 7 and the warning light 6 are connected by wires. The bottom of the warning light 6 has a straight opening, into which an insulating insulating plate is inserted and tied to the ladder part of the well by a rope 9. When the warning light 6 floats out of the well, the insulating insulating plate falls off, at which time the circuit between the warning light 6 and the battery 7 is connected, and the lighting warning state is activated.

[0033] In some embodiments of this utility model, the warning device also includes a warning flag 8 disposed at the upper end of the main pole, which serves as a daytime warning.

[0034] In some embodiments of this invention, the vertical pole is made of a transparent plastic tube (at least the mother pole 3 can be made of a transparent plastic tube, and the daughter pole 4 can also be made of a transparent plastic tube). An LED light strip is installed inside the vertical pole and is connected to a battery for nighttime illumination and warning. Furthermore, a reflective strip is affixed to the surface of the vertical pole, reflecting light under illumination (such as vehicle headlights, mobile phone flashlights, etc.), helping vehicles or pedestrians to see it and reducing the likelihood of vehicles or pedestrians falling into storm drains / sewage wells.

[0035] This utility model's rainwater / sewage well anti-fall warning device is easy to install, requires no daily maintenance, and automatically extends out of the well opening as the water level in the well rises to provide a warning when the well cover is missing. It is simple to install, highly adaptable, and effectively improves safety. Furthermore, this device can be used not only during the day but also at night to provide illumination and warning, and its length can be adjusted according to different well depths via a telescopic structure. It solves the technical problem of effectively reducing the probability of pedestrians falling into rainwater / sewage wells.
