Description

Technical Field

[0001] The invention belongs to the technical field of drainage facilities and relates to a foldable, liftable and easy-to-clean drainage grate. Background Art

[0002] Drain grates are a commonly used auxiliary device in ground drainage facilities. They are widely used in municipal roads, garden equipment, bathhouses, factories and other places. In urban construction and flushing operations, drain grates are equivalent to the entrance of drainage facilities, which directly affects the collection and discharge of rainwater and wastewater. Drain grates are mainly used to intercept garbage, which can improve the treatment effect of drainage facilities and prevent sewer blockage.

[0003] At present, existing drainage grates often adopt fixed and flat designs. When small debris and garbage such as leaves and gravel fall from the drainage grates into the drainage ditches and sewers, they accumulate at the bottom, affecting the drainage efficiency and increasing the probability of urban waterlogging. In addition, since the garbage sinks to the bottom, it is not easy to be noticed and difficult to remove, which is extremely inconvenient. In the long run, the garbage such as leaves and dirt corrodes into sludge deposits, causing more serious blockages and environmental pollution, and increasing the difficulty of drainage treatment. In addition, when pedestrians' belongings fall into the drainage ditches and sewers, there are situations where they cannot be removed in time or are difficult to remove. There are also situations where small animals such as weasels and mice drill into the pipes from the grates and damage the inside of the pipes. When the drainage grates are in the open state, there are also safety hazards such as falling into the drainage ditches. Summary of the invention

[0004] The purpose of the present invention is to provide a foldable, liftable and easy-to-clean drainage grate in order to solve the above problems and special circumstances.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A foldable, liftable and easy-to-clean drainage grate comprises a supporting grate sleeve, a top flip grate plate and a lifting grate plate.

[0007] The supporting grate sleeve is an open structure, and a symmetrical fixed bottom plate is provided on one side of the outer wall of the supporting grate sleeve, a top flip grate plate is provided above the supporting grate sleeve, and a lifting grate plate is provided below. An axial hole is provided on one side of the outer wall of the top flip grate plate, and a connecting seat is installed on the outer wall of the supporting grate sleeve. The axial hole is hingedly fixed to the connecting seat, and the maximum rotation angle can be changed by designing the height of the connecting seat.

[0008] Furthermore, the top flip cover grate plate and the lifting grate plate are connected to each other through rods and rivets, and the rods are retractable connecting rods, which ensure that they are in a stretched state when open to increase linkage, and are compressed to restore when closed. The top flip cover grate plate and the lifting grate plate are symmetrically installed in combination, each with a set of rods and rivets, and the combination is symmetrically installed.

[0009] Furthermore, the lifting grate plate and the supporting grate sleeve are connected by rods and rivets, and two sets of rods and rivet combinations are respectively provided on the two side walls of the lifting grate plate and the supporting grate sleeve, and the combination is symmetrically installed to ensure that the lifting grate plate is horizontal in the closed state. In addition, if damage occurs, it can be disassembled and replaced in a targeted manner, reducing maintenance and repair costs.

[0010] Furthermore, the first row of grate holes of the top flip grate plate is designed differently from other rows of grate holes. Since the width of the lifting grate plate does not reach directly below the first row, the grate holes in this row are slightly smaller than other rows of grate holes.

[0011] Furthermore, the grate holes of the lifting grate plate and the top flip grate plate are perpendicular to each other in space, the number of grate holes is greater than that of the top flip grate plate, and the grate hole width is smaller than that of the top flip grate plate.

[0012] By adopting the above technical solution, the present invention not only optimizes the double-layer grate design of ordinary water grates, but also improves the shortcomings of double-layer grates that are difficult to clean and easy to clog. When cleaning, opening the top grate plate can automatically lift the second layer of fine garbage, which is conducive to cleaning and improves the drainage rate; at the same time, due to the combined configuration of the rods, the garbage can be lifted to the same height as the ground without any seams, which is equivalent to cleaning on a flat surface, which will reduce the difficulty of cleaning and improve the cleaning efficiency. In addition, it can be improved according to the usage scenario to facilitate cleaning and speed up the cleaning efficiency.

[0013] In summary, the advantages of the present invention are:

[0014] 1. By setting up double-layer grate plates, garbage and debris can be graded and blocked, reducing the accumulation at the bottom and reducing the difficulty of drainage treatment. At the same time, the two-layer design also prevents small animals such as weasels and mice from entering the pipes, protecting the safety of pipes and animals. If pedestrians and items fall into the gutter or sewer, they can be taken out in time and conveniently.

[0015] 2. By setting up a lifting mechanism and a design that seamlessly connects to the ground, the present invention is easier for cleaning staff to clean than traditional grates, has good practicality, and improves the efficiency and completion of the cleaning work; at the same time, it allows cleaning staff to more easily find accumulated garbage, and can discover and clean it in time to prevent blockage.

[0016] 3. The material and size of the present invention can be changed according to the applicable occasions, and can be improved according to local conditions. It can be applied to a variety of occasions, such as municipal roads, gardens, bathhouses, factories and other places, making cleaning work more convenient, with high flexibility and strong plasticity.

[0017] 4. The present invention is not only well designed and highly applicable, but also has a simple production process, is extremely convenient to assemble and place, and is extremely easy to process and shape using existing materials and technologies, making it suitable for mass production and popularization.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 4As shown, a foldable, lifting and easy-to-clean drainage grate includes a supporting grate sleeve 1, the top and bottom of the supporting grate sleeve 1 are both open structures, and the top, bottom and center are empty, which is convenient for water to flow through the supporting grate sleeve 1. The outer wall of the supporting grate sleeve 1 is provided with a fixed bottom plate 6, and the installer can fix the device by fixing the bottom edge with bolts. A connecting seat 8 is installed on the outer wall of the supporting grate sleeve 1, and the movable block 9 is hinged and fixed to the connecting seat 8. The stability of the movable block 9 on the supporting grate sleeve 1 can be ensured by symmetrically arranging the connecting seat 8 and the movable block 9, so that the top flip cover grate plate 3 can be flipped along one side of the supporting grate sleeve 1, and the stability of the lifting device when in use can be improved, and the rotation range can be adjusted in design according to the retractable connecting rod 5 and the connecting seat 8.

[0026] The top flip grate plate 3 and the lifting grate plate are connected to each other through rods and rivets, and the rods are retractable connecting rods 5. The top flip grate plate 3 and the lifting grate plate 2 are symmetrically installed in combination, each having a set of rods and rivets, and the combination is symmetrically installed.

[0027] The lifting grate plate 2 and the supporting grate sleeve 1 are connected by rods and rivets. Two sets of rods and rivets are respectively provided on the two side walls of the lifting grate plate 2 and the supporting grate sleeve 1. The combination is symmetrically installed to ensure that the lifting grate plate 2 is horizontal in the closed state. In addition, if damage occurs, it can be disassembled and replaced in a targeted manner, reducing maintenance and repair costs.

[0028] The first row of grate holes of the top flip grate plate 3 is designed differently from other rows of grate holes. Since the width of the lifting grate plate does not reach directly below the first row, the grate holes in this row are slightly smaller than other rows of grate holes.

[0029] In the embodiment of the present invention, there are 4 flat-headed rods 7, 8 corresponding mortise and tenon joints, and 8 corresponding rivet holes. Two groups of rods and rivets are symmetrically arranged on each side, with 1 flat-headed rod 7 in each group. The 2 mortise and tenon joints can ensure that the lifting grate plate in the closed state is in a horizontal state and that the telescopic connecting rod 5 is shortened to a minimum. When the top flip grate plate 3 is flipped over, the telescopic connecting rod 5 connecting the top flip grate plate 3 and the lifting grate plate 2 will be driven and stretched until the top flip grate plate 3 is flipped over to a predetermined position, that is, the position obtained by designing the height of the connecting seat, and at this time, the telescopic connecting rod 5 is stretched to the maximum position. At the same time, due to the movement and stretching of the telescopic connecting rod 5, the lifting grate plate 2 moves to the upper left until the telescopic connecting rod 5 reaches the specified position, at which time the lifting grate plate 2 is parallel to the supporting grate sleeve 1. At the same time, the flat head rod 7 rotates around the rivet hole 13 on the supporting grate sleeve 1 as the lifting grate plate 2 moves, and the flat head rod 7 is parallel to the horizon. The opening state of the present invention is as described above, and the staff can use cleaning tools to clean up the garbage or passers-by can pick up the dropped objects.

[0030] On the contrary, when the top flip cover grate plate 3 is closed, the retractable connecting rod 5 will be driven and contracted to the minimum length, driving the lifting grate plate 2 to fall back to the original state, and at this time, the flat head rod 7 rotates around the rivet hole 13 until it is perpendicular to the horizon. There are 4 reserved holes 11, all located on the top flip cover grate plate 3, which can reserve positions for the flat head rod 7 in the closed state. The closed state of the present invention is as described above, and people and vehicles can pass normally.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
