Technical Field
[0001] The utility model belongs to the technical field of grilles, and in particular relates to a novel water-conducting anti-falling grille. Background Art
[0002] The grille is a steel product made of flat steel arranged crosswise at a certain spacing and crossbars, and welded into a square grid in the middle. It is mainly used for ditch covers, steel structure platform plates, steel ladder treads, etc. The crossbars are generally made of twisted square steel to prevent oxidation. It can also be made of stainless steel. The grille has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.
[0003] However, there are some problems with the existing technology: the manhole is generally covered with a manhole cover. When performing emergency rescue water diversion tasks, the manhole cover needs to be opened to extend the water hose into the sewer, which will expose the sewer and easily cause people to fall. The water hose is directly placed on the cement sewer opening, and the bending angle of the water hose is too large, resulting in a reduction in the amount of water pumped per unit time, thereby increasing energy consumption, reducing work efficiency, and easily causing wear and tear, and even causing the water hose to rupture. Therefore, we propose a new type of water diversion anti-falling grille. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a new type of water-guiding anti-falling grille. By setting a movable grille, the movable grille can be opened and closed freely during emergency water-guiding operations, and can also prevent people from slipping and falling.
[0005] The utility model is implemented as follows: a novel water-conducting anti-falling grille comprises an edge ring plate, the edge ring plate is in a circular ring shape, a hollow area is formed, and the grille is welded, a connecting seat is fixedly connected to the edge ring plate, a claw ring is welded at the lower end of the edge ring plate, and the claw ring has a diameter smaller than the edge ring plate and is used to place the grille;
[0006] A fixed grille is welded in the hollow area of the edge ring plate, and a movable grille is arranged on the connecting seat. The movable grille can be unfolded through the connecting seat to form an angle with the surface of the edge ring plate, and a bent pipe is connected to the edge ring plate by bolts.
[0007] Optionally, a first avoidance groove is formed on the fixed grille, and a second avoidance groove is formed on the movable grille, and the first avoidance groove is aligned with the second avoidance groove to form a through-pipe area.
[0008] Optionally, the number of the fixed grilles is two, and the two fixed grilles are distributed circumferentially on the edge ring plate and located in the hollow area.
[0009] Optionally, an annular corner is welded on the outer side of the fixed grille to prevent the grille from being deformed due to stress.
[0010] Optionally, a handle is provided on the movable grille, and an arc-shaped corner is welded on the movable grille.
[0011] Optionally, the curved pipe is in an arc shape and passes through the through-pipe area. A protective cover is hinged on the curved pipe, and the protective cover is buckled with the curved pipe.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. By setting a claw ring under the edge ring plate, during installation, since the claw ring and the edge ring plate form a step, the fixed grille and the movable grille can be directly placed in the hollow area of the edge ring plate, and the welded claw ring has sufficient supporting force. When the welding part between the grille and the edge ring plate is aged or damaged and falls off, the claw ring can also support the grille to prevent the grille from falling directly.
[0014] 2. By bolting the bend on the side ring plate, and the bend passes through the grille through the pipe area, when water needs to be diverted, place the water hose in the bend. The protective cover can reduce the bending angle of the water hose, increase the water diversion amount per unit time, and protect the bending part of the water hose, effectively preventing wear on the corners of the water hose and the sewer.

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0022] like Figures 1 to 4 As shown, a new type of water-guiding anti-falling grille provided by an embodiment of the utility model includes an edge ring plate 1, which is in a circular ring shape and forms a hollow area for welding the grille. A connecting seat 11 is fixedly connected to the edge ring plate 1, and a claw ring 12 is welded at the lower end of the edge ring plate 1. The diameter of the claw ring 12 is smaller than that of the edge ring plate 1 and is used to place the grille.
[0023] It should be noted that the utility model is aimed at the insufficient anti-fall protection measures when used in emergency rescue water diversion tasks. It is used to prevent people from slipping and falling due to exposure of the sewer entrance when reaching water, thereby improving the safety factor. It can also reduce the bending angle of the water hose during water diversion operations, increase the water diversion volume per unit time, and reduce the piercing of the bottom of the water hose by sharp components such as well hooks.
[0024] Specifically, a fixed grille 2 is welded in the hollow area of the edge ring plate 1, and a movable grille 3 is arranged on the connecting seat 11. The movable grille 3 can be unfolded through the connecting seat 11 to form an angle with the surface of the edge ring plate 1, and a bent pipe 4 is connected to the edge ring plate 1 by bolts.
[0025] Specifically, a first avoidance groove 22 is formed on the fixed grille 2, and a second avoidance groove 32 is formed on the movable grille 3. The first avoidance groove 22 is aligned with the second avoidance groove 32 to form a through-pipe area.
[0026] Specifically, there are two fixed grilles 2, which are circumferentially distributed on the edge ring plate 1 and located in the hollow area. An annular corner 21 is welded on the outer side of the fixed grille 2 to prevent the grille from being deformed by force. A handle 31 is provided on the movable grille 3, and an arc corner 33 is welded on the movable grille 3.
[0027] Furthermore, the shapes of the fixed grille 2 and the movable grille 3 are set to correspond to the hollow area of the edge ring plate 1, so that the two fixed grilles 2 and the movable grille 3 can cooperate to completely cover the entire hollow area of the edge ring plate 1, and the edges of the fixed grille 2 and the movable grille 3 are welded with metal corners, which can effectively prevent the fixed grille 2 and the movable grille 3 from deformation due to long-term use, and the annular corner 21 and the arc corner 33 can effectively support the fixed grille 2 and the movable grille 3.
[0028] Specifically, the curved pipe 4 is in an arc shape and passes through the through-pipe area. A protective cover 41 is hinged on the curved pipe 4 , and the protective cover 41 is buckled with the curved pipe 4 .
[0029] Furthermore, the bending angle of the bent pipe 4 is not less than 120°, the bent pipe 4 is connected to the edge ring plate 1 by bolts, the bent pipe 4 can be rotated by the bolt connection, and the bent pipe 4 can be disassembled by bolt connection, and when in use, it can be installed by bolt plugging;
[0030] Furthermore, since the volume of the bent pipe 4 is large, it will take up more space, and the material of the side ring plate 1 is metal, and the material of the bent pipe 4 can be plastic or other economical materials. When stored, the metal side ring plate 1 is easy to cause damage to the bent pipe 4. The bent pipe 4 is separated from the side ring plate 1 by bolt connection, which is convenient for storage and prevents damage to the bent pipe 4; Figure 4 As shown, the curved pipe 4 is arc-shaped, so a plurality of curved pipes 4 can be stacked and stored.
[0031] Furthermore, the protective cover 41 is located in the middle area of the bend of the elbow 4. When the water hose is draining water, the water hose expands due to the impact of the water flow, and the force on the bend of the water hose is the greatest. When subjected to external force, the water hose is more likely to be damaged. Therefore, the protective cover 41 located in the middle of the bend of the elbow 4 can effectively prevent foreign objects from directly causing damage to the bend of the water hose, and the protective cover 41 is interlocked with the elbow 4. A handle is welded on the protective cover 41 to facilitate opening and closing the protective cover 41, and a hook is welded on the elbow 4 to hook the beater for fixing.
[0032] Exemplarily, the new water-guiding anti-falling grille has a circular shape, the outer diameter of the edge ring plate 1 is 750mm, the inner diameter is 600mm, the movable grille 3 is connected to the edge ring plate 1 through a 20mm*10mm connecting seat 11, and a claw ring 12 with a specification of 600mm*2mm*50mm is arranged on the back of the edge ring plate 1. A through pipe area is formed between the fixed grille 2 and the movable grille 3, and two semi-open and detachable protective sleeves are installed in the through pipe area. The specifications of the protective sleeve are: total length 400mm, a bending angle of 120° at the half section of the sleeve, and a pipe diameter of DN250mm.
[0033] Working principle: a claw ring 12 is welded under the edge ring plate 1, and the claw ring 12 forms a step with the edge ring plate 1. During installation, the fixed grille 2 and the movable grille 3 can be directly placed in the hollow area of the edge ring plate 1, and the welded claw ring 12 has sufficient supporting force to prevent the fixed grille 2 from aging or being damaged and falling off at the welding point between the fixed grille 2 and the edge ring plate 1. The claw ring 12 can also support the fixed grille 2 to prevent the fixed grille 2 from falling directly. The elbow 4 connected to the edge ring plate 1 by bolts rotates through the through pipe area. When conducting water, the water hose is placed in the elbow 4. The protective cover 41 can protect the bending part of the water hose, and the elbow 4 can effectively prevent the water hose from wearing at the corner of the sewer.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
