Description

Technology Field

[0001] The present invention relates to a location identification safety device for a manhole cover or grating that can prevent damage and enhance safety through a collision prevention function. More specifically, the invention relates to a location identification safety device for a manhole cover or grating that can prevent damage and enhance safety through a collision prevention function, which allows the location of the manhole cover or grating formed on a roadway or sidewalk to allow rainwater or sewage to flow in to be recognized through a light-emitting part capable of emitting or reflecting light, and ensures safety by preventing collisions with the light-emitting part protruding upward so that pedestrians or drivers can easily identify the light-emitting part. Background Technology

[0002] Typically, manholes and gratings are installed on roadways or sidewalks to allow rainwater or sewage to flow into underground pipes and be transported to treatment plants, as they are connected to water and sewage systems. However, these manhole covers and gratings are difficult to identify in the dark at night, making it hard to confirm their location. To prevent this, separate reflective panels were attached to allow people to bypass or recognize the locations where the covers or gratings were installed. However, attaching separate reflective panels to flat manhole covers or gratings was difficult, and even if attached, visibility was reduced. Consequently, they were formed in a protruding shape; however, this design led to collision accidents caused by the protruding reflective panels, making it difficult to simultaneously achieve both nighttime visibility and safety.

[0003] For example, according to Korean Registered Patent No. 2217218 (Prior Art 1), end bars (30) are welded to both ends of a reinforcing beam (20), and an A-type bearing bar (40) is installed between the reinforcing beams (20). The A-type bearing bar (40) is formed by bending a vertical plate (43) having inclined surfaces (42) formed on both sides of a horizontal plate (41), and forming coupling grooves (44) at equal intervals on the horizontal plate (41) and the inclined surfaces (42) to form the A-type bearing bar (40). A plate-shaped crossbar (50) is installed in a grid pattern in the coupling grooves (44) of the A-type bearing bar (40), and a reflector plate (46) is bonded and fixed to the inclined surfaces (42) of the A-type bearing bar (40). In configuring a steel grating, horizontal cutting sections (52) are formed at both ends of the crossbar (50). The present invention provides a steel grating that improves stress against load, nighttime visibility, and workability, characterized by positioning the upper plate (21) of the reinforcing beam (20) on the horizontal cutting section (52) above, and configuring the length (L3) of the horizontal cutting section (52) of the crossbar (50) to be shorter than the inner surface length (L4) of the upper plate (21) of the reinforcing beam (20), so that the ends of both sides of the crossbar (50) do not come into contact with the inner surface (24) of the reinforcing beam (20), thereby making it easy to assemble the crossbar (50) installed between the reinforcing beams (20).

[0004] However, the steel grating, which improves reinforcement stress against such loads, night visibility, and workability, could not guarantee safety because the reflector is formed inside between the A-type bearing bars (40), so pedestrians or vehicles can only perceive the light when they reach a specific angle.

Specific details for implementing the invention

[0016] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0017] The present invention relates to a safety device for confirming the location of a manhole cover or grating (1) that can ensure safety in situations where visibility is poor, such as at night, and comprises a main body (10), a fixing means (20), a light-emitting part (30), a detachment prevention means (40), and an operating means (50) as its main components.

[0018] The main body (10) according to the present invention is provided with a receiving groove (12) with an open top that is inserted into a seating groove (11) formed on the upper surface of the manhole cover or grating (1). Although the main body (10) is formed in a square shape in the drawing, it may be formed in a circular or polygonal shape. The main body (10) is inserted into a seating groove (11) formed in the manhole cover or grating (1). In the case of the manhole cover, it is formed in a groove shape, but in the case of the grating (1), since a plurality of bars are formed at regular intervals, the seating groove (11) is formed with some of the bars cut out, and the main body (10) may have a hanging groove (15) formed at the bottom so that the cut bars (2) of the seating groove (11) are inserted. In addition, the main body (10) has a receiving groove (12) formed with an open top that forms a receiving space.

[0019] Additionally, the fixing means (20) according to the present invention is configured so that the main body (10) can be fixed to a seating groove (11) formed on the upper surface of a manhole cover or grating (1). The fixing means (20) enables the main body (10) to be fixed so that the manhole cover or grating (1) does not detach to the outside while inserted into the seating groove (11).

[0020] At this time, the fixing means (20) comprises a fixing plate (21) that is seated on the lower surface of a manhole cover or grating (1) so that the main body (10) can be fixed to a seating groove (11) formed on the upper surface of the manhole cover or grating (1), and a fastening configuration (22) that has a fastening bolt (23) that sequentially fastens the fixing plate (21) and the lower part of the main body (10) to fix it, or a slide configuration (24) that has a slide groove (25) formed on the lower part of the main body (10), a fixing bolt (26) whose upper part is inserted into the slide groove (25) and whose lower part penetrates the fixing plate (21), and a nut (27) that is fastened on the fixing bolt (26) and allows for precise adjustment of the fixing according to the thickness of the manhole cover or grating (1), a guide rod (28a) having upper and lower heads (28b) (28c) at both ends, and the guide rod (28a) at the lower part of the light-emitting part (30). It is characterized by having one of the following guide configurations to guide the up and down movement of the light-emitting part (30): a first side groove (29a) that accommodates the upper head (28b), a guide hole (29b) through which the guide rod (28a) passes on the main body part (10), and a second side groove (29c) that accommodates the lower head (28c) of the guide rod (28a) on the fixing plate (21). The fixing means (20) is formed with a fastening configuration (22), a slide configuration (24), and a guide configuration (28). First, in the case of the fastening configuration (22), when the cut slat (2) of the seating groove (11) is inserted into the main body part (10) through the hanging groove (15), the fixing plate (21) is in close contact with the lower surface of the cut slat (2), and the fixing plate (21) and the main body part (11) are fastened and fixed through a fastening bolt (23). In the case of the slide configuration (24), a slide groove (25) is formed in the lower part of the main body (10), and the upper part of the fixing bolt (26) is inserted into the slide groove (25), while the lower part penetrates the fixing plate (21), and the fixing bolt (26) is fixed by fastening a nut (27) to it. Here, the nut (27) is fastened by adjusting it to the thickness of the cut slats (2), thereby enabling tight fastening.In this way, even in the case of the manhole cover, tight fixing force is exerted by adjusting the fastening with a nut (27) according to the thickness. The nut (27) is formed to adjust tight fixing force according to the thickness; although it is possible to fix the fixing plate (21) by fastening the fixing bolt (26) without the nut (27), this would cause inconvenience in the work, so it is appropriate to obtain tight fixing force through the nut (27). Furthermore, the guide configuration (28) is an auxiliary component of the operating means (50) formed in the center, which will be described later, and allows the light-emitting part (30) that moves up and down to move more smoothly and prevent detachment. That is, since the light-emitting part (30) is fixed against external pressure by only the operating means (50), the fixing force of the operating means (50) may be released due to external pressure and detachment, so the guide configuration (28) is provided to prevent this. In this guide configuration (28), a guide rod (28a) is formed having upper and lower heads (28b) (28c) at each of the upper and lower ends, and the upper head (28b) is inserted into the first side groove (29a) formed on the light-emitting part (30) and the lower head (28c) is inserted into the second side groove (29c) of the fixing plate (21), and the guide hole (29b) of the main body (10) is maintained in a state where it penetrates. This facilitates easy mounting and helps the light-emitting part (30) move smoothly, while also assisting in the detachment of the light-emitting part (30).

[0021] Additionally, the light-emitting part (30) according to the present invention is installed in the receiving groove (12) of the main body (10) and maintains a state of protruding upward so that pedestrians (3) or vehicles, etc., can identify the location of the manhole cover or grating (1) through light emission or light reflection. The light-emitting part (30) is formed in the receiving groove (12) formed in the main body (10) and is formed to protrude upward to create a state of easier identification for pedestrians (3) or drivers of vehicles at night. This light-emitting part (30) can emit light by supplying power such as a battery or cell battery inside, or it can also be configured to reflect a separate light or accumulate and emit light like a glow-in-the-dark light.

[0022] Additionally, the anti-detachment means (40) according to the present invention is provided so that the light-emitting part (30) does not detach from the receiving groove (12) of the main body (10). Since the light-emitting part (30) is received in the receiving groove (12) of the main body (10), the anti-detachment means (40) is configured to solve the problem of the light-emitting part (30) being separated and detached from the outside.

[0023] At this time, the above-mentioned anti-detachment means (40) is characterized by the inner wall surface (41) of the receiving groove (12) being formed in a shape that narrows from bottom to top so that the light-emitting part (30) does not detach from the receiving groove (12) of the main body (10). The anti-detachment means (40) prevents the light-emitting part (30) from detaching from the outside by forming the inner wall surface (41) of the receiving groove (12) in a shape that narrows from bottom to top so that the light-emitting part (30) is moved up and down within the receiving groove (12) by the operating means (50), as will be explained later, without hindering this movement.

[0024] Additionally, the operating means (50) according to the present invention prevents the light-emitting part (30) from detaching from the main body (10) and induces the light-emitting part (30) to move up and down by means of elastic force due to pressure applied from above, thereby preventing collision with pedestrians (3) or vehicles, thereby ensuring safety and preventing damage. The operating means (50) is configured such that the light-emitting part (30), which is protruding upward to be recognizable at night, naturally moves downward to prevent collision when a pedestrian (3) or vehicle passes by, and then allows the light-emitting part (30) to naturally move upward again after the pedestrian (3) or vehicle has passed.

[0025] At this time, the above operating means (50) is characterized by having a fixing groove (51) formed in the receiving groove (12) of the main body (10) to prevent the light-emitting part (30) from detaching and to induce the light-emitting part (30) to move up and down by elastic force due to pressure applied from above, thereby preventing safety and damage by preventing collision with pedestrians (3) or vehicles, a spring (52) that supports the light-emitting part (30) by being seated on the fixing groove (51), a screw tap part (53) that protrudes integrally from the lower part of the light-emitting part (30), a through hole (54) that penetrates to the outside while the screw tap part (53) is inserted between the spring (52) in the center of the fixing groove (51), a fixing hole (56) formed in the fixing plate (21) that coincides with the through hole (54), and a fixing pin (55) that is fastened to the screw tap part (53). First, the operating means (50) has a fixing groove (51) formed so that one side of the spring (52) can be seated on the receiving groove (12) of the main body (10), and another through hole (54) is formed in the center of the fixing groove (51). Then, a light-emitting part (30) capable of emitting or reflecting light is seated on the upper part of the spring (52) seated in the fixing groove (51), and a screw tap part (53) that protrudes integrally from the lower part of the light-emitting part (30) passes through the center of the circularly twisted part of the spring (52) and also passes through the through hole (54). After that, the fixing hole (56) formed in the fixing plate (21) of the fixing means (20) described above for fixing the main body (10) is penetrated so as to coincide with the through hole (54), so that the screw tap part (53) also penetrates the fixing hole (56), and the end of the penetrated screw tap part (53) is fastened with the fixing pin (55), so that when pressure is applied to the upper part of the light-emitting part (30), the light-emitting part (30) moves in the downward direction, and when the pressure is released, it is restored by the spring (52).

[0026] At this time, the main body (10) is further provided with a barrier (13) to prevent foreign substances from entering the receiving groove (12) by blocking the gap between the light-emitting part (30) that is attached to the upper surface and the main body (10) that is inserted into the receiving groove (12). In the case of the main body (10), a receiving groove (12) is formed to accommodate the light-emitting part (30). If foreign substances enter the interior of the receiving groove (12), it acts as a factor that hinders the light-emitting part (30) that must move up and down. Therefore, to prevent this, a barrier (13) can be formed to prevent foreign substances from entering by blocking the gap between the main body (10) that is attached to the upper surface and the light-emitting part (30) that is inserted into the receiving groove (12).

[0027] In addition, the receiving groove (12) of the main body (10) is characterized by having one or more discharge holes (14) so ​​that foreign substances, etc., that have entered the interior are discharged downward. Although the entry of foreign substances, etc. into the interior of the receiving groove (12) can be prevented through the aforementioned barrier (13), one or more discharge holes (14) are formed and provided so that fine dust or foreign substances that have inevitably entered can be discharged downward. It is suitable for such discharge holes (14) to be formed at a location that does not interfere with the configured fixing means (20), and since it is suitable for falling foreign substances, etc. to be discharged directly into the discharge holes (14), they can be formed directly below the gap with the light-emitting part (30) inserted into the receiving groove (12), so it is good to adjust the appropriate position of the fixing means (20).

[0028] Thus, the present invention enables the location of a manhole cover or grating formed on a roadway or sidewalk, etc., for receiving rainwater or sewage, to be recognized through a light-emitting part capable of emitting or reflecting light, and provides the effect of ensuring safety by preventing collision with a light-emitting part protruding upward, thereby making it easy for pedestrians or drivers to identify the light-emitting part.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the invention. Accordingly, such variations or modifications should be considered to fall within the scope of the patent claims of the present invention. Explanation of the symbols
