Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water supply and drainage, in particular to a drainage equipment capable of preventing blockage. BACKGROUND

[0002] Water supply and drainage is a very important part in the design and construction process of buildings. A good water supply and drainage system can ensure that accumulated water can be quickly drained, avoiding flood disasters and ensuring the safety of buildings and people.

[0003] Precipitation is the main object of water supply and drainage system processing. Precipitation in the form of rain, snow and the like contains a large amount of impurities such as leaves, garbage and soil, which can easily cause the water supply and drainage system to be blocked. Therefore, an interception or filtering device is usually arranged at the water inlet to intercept impurities that may cause blockage. For example, CN221646191U discloses a water supply and drainage structure. When the filter screen plate needs to be taken out for cleaning, the rectangular frame will be popped up under the action of the spring to reduce or even prevent water from flowing in, thereby achieving the effect of avoiding the impurities in the water from blocking the water collecting cavity after the filter screen plate is taken out.

[0004] However, when the above-mentioned patent adopts a pop-up structure design, the height of the popped-up rectangular frame is limited, and when the depth of accumulated water is large, it cannot play the expected interception role, so there is still a risk of blockage by impurities. Content of the utility model

[0005] The present application provides a drainage equipment capable of preventing blockage, which solves the problem that the vertically upward-popped structure in the prior art has a limited height and cannot completely avoid blockage.

[0006] The present application provides a drainage equipment capable of preventing blockage, which includes:

[0007] The outer frame includes a rectangular top frame and side frames arranged at the bottom of the opposite sides of the top frame.

[0008] The side plates are vertically rotatably arranged at the other opposite sides of the bottom of the top frame. When the two side plates are rotated upward to the highest position, the top frame is blocked. The end of the side plate is provided with a convex edge.

[0009] The filter screen is placed on the convex edge when the two side plates are rotated to the lowest position.

[0010] In one possible implementation, the inner side surface and the bottom surface of the top frame are respectively provided with an inner limiting portion and a bottom limiting portion. The side plates are arranged between the inner limiting portion and the bottom limiting portion. The side plates stop rotating when rotated to the highest position and the lowest position under the blocking of the inner limiting portion and the bottom limiting portion.

[0011] In a possible implementation, the bottom surface of the inner limiting part is a horizontal surface, and the side plate is in a horizontal state when it is rotated to the highest position under the blocking of the inner limiting part.

[0012] In a possible implementation, the bottom surface of the inner limiting part is a slope surface facing downward, and the side plate is in an upwardly inclined state when it is rotated to the highest position under the blocking of the inner limiting part.

[0013] In a possible implementation, a partition is arranged in the top frame, and the partition divides the internal space of the top frame into two sub-frames, and each side plate is used to block one sub-frame.

[0014] In a possible implementation, the side plate is arranged at the bottom of the top frame in a vertical rotation mode through a rotating shaft, a torsional spring is arranged on the rotating shaft, and the torsional spring provides elastic force for upward rotation of the side plate.

[0015] In a possible implementation, a handle is arranged on the top surface of the filter screen.

[0016] The drainage equipment for preventing blockage in the application has the following advantages:

[0017] The design of overturning is adopted, the filter screen is inserted between the two side plates during filtration, and the filter screen can be taken out from between the side plates when a large amount of impurities is accumulated on the filter screen, at this time, the side plates can completely block the top frame, and any water and impurities cannot enter, thereby fundamentally solving the problem of blockage of impurities when the filter screen is taken out.

[0026] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] Figures 1-6 Fig. 1 is a schematic view of the structure of a water supply and drainage system according to an embodiment of the present application. The embodiment of the present application provides a water supply and drainage system, which comprises:

[0028] The outer frame 110 comprises a rectangular top frame and side frames arranged at the bottom of the opposite sides of the top frame;

[0029] The side plates 130 are vertically arranged at the bottom of the other opposite sides of the top frame. When the two side plates 130 are rotated to the highest position, the top frame is blocked. The end of the side plate 130 is provided with a convex edge 131.

[0030] The filter screen 140 is placed on the convex edge 131 when the two side plates 130 are rotated to the lowest position.

[0031] For example, the top frame is a rectangular frame formed by cutting a rectangular plate to remove a rectangular region in the center. The width of the four sides of the top frame is the same. The side frames and the side plates 130 are respectively connected to the positions near the inner edges of the bottom surface of the top frame. The inner side surface of the side frame is flush with the inner side surface of the top frame. Therefore, the top frame forms a convex platform on the outer side of the side frame and the side plate 130. The convex platform is used to overlap the upper edge of the drainage hole of the fixed object 200. When the top frame overlaps the fixed object 200, the bottom of the top frame can be closely attached to the surface of the fixed object 200 to reduce the amount of water flowing through the gap between the top frame and the fixed object 200.

[0032] It should be understood that the fixed object 200 is any object on which the water supply and drainage system 100 of the embodiment of the present application is installed, such as a roof, a road surface, etc. A drainage hole with a size and shape corresponding to the rectangle surrounded by the side frame and the side plates 130 in the embodiment of the present application is pre-formed on the fixed object 200, and then the entire water supply and drainage system 100 is placed in the drainage hole.

[0033] The side plates 130 are connected to the bottom surface of the top frame by horizontally arranged rotating shafts, so that the side plates 130 can rotate in the vertical direction. When the side plates 130 are rotated to the highest position, the ends of the two side plates 130 abut against each other to be kept stable under the abutting pressure, and the structure formed after the two side plates 130 abut against each other can block the opening of the top frame, so as to prevent water from entering.

[0034] In the embodiment of the present application, the ends of the side plates 130 are provided with elastic sealing strips, and the sum of the widths of the two side plates 130 and the two sealing strips is slightly greater than the width of the opening of the top frame. Therefore, when the side plates 130 are rotated upward to the highest position, the two sealing strips will contact and press against each other. When the side plates 130 continue to rotate upward, the sealing strips will be elastically deformed, which will provide a reverse pressure to the side plates 130. When the highest position of the side plates 130 is horizontal or inclined upward, the pressure generated by the sealing strips can keep the side plates 130 in a stable state, and the side plates 130 will not be automatically opened in an unstable state.

[0035] When the side plates 130 are rotated to the lowest position, i.e. in the vertical direction, the side plates 130 and the side frame will surround a rectangular channel, and water will flow into the channel from the upper end and flow out from the lower end. The shape and size of the filter screen 140 are the same as the cross section of the channel, and the filter screen 140 can filter the water flowing through when the filter screen 140 is inserted into the channel.

[0036] When the filter screen 140 needs to be replaced or cleaned after a long time of use, the filter screen 140 can be taken out of the channel. At this time, the side plates 130 are rotated upward to block the opening of the top frame, so as to prevent water from entering. When the new filter screen 140 is ready or the cleaning is completed, the side plates 130 can be opened, and the filter screen 140 can be inserted into the channel. Since the side plates 130 are provided with the convex edges 131, the filter screen 140 can be placed on the convex edges 131, so as to avoid the downward sliding of the filter screen 140. It should be understood that the convex edges 131 can also be arranged at the ends of the side frame, which can achieve the same effect as the convex edges 131 arranged at the ends of the side plates 130.

[0037] In the embodiment of the present application, the top surface of the filter screen 140 is provided with a handle 141. The handle 141 is fixed to the filter screen 140 by welding, and the handle 141 can be easily held when the filter screen 140 is taken out or installed.

[0038] In a possible embodiment, the inner side surface of the top frame and the bottom surface are respectively provided with an inner limiting part and a bottom limiting part, and the side plate 130 is arranged between the inner limiting part and the bottom limiting part, and the side plate 130 stops rotating when rotating to the highest position and the lowest position under the blocking of the inner limiting part and the bottom limiting part.

[0039] Exemplarily, the position where the side plate 130 is mounted on the bottom surface of the top frame is not flush with the inner side surface of the top frame, and there is a protruding part of the inner side surface of the top frame relative to the side plate 130, which is the inner limiting part, and the side plate 130 stops rotating when rotating to the position close to the inner limiting part, at which time the side plate 130 is in the highest position. And the bottom surface of the top frame is provided with a protruding bottom limiting part, and the side plate 130 will be close to the bottom limiting part when rotating to the vertical state, and then stops rotating under the blocking of the bottom limiting part, at which time the side plate 130 is in the lowest position.

[0040] In an embodiment of the present application, the bottom surface of the inner limiting part is a horizontal surface, and the side plate 130 is in a horizontal state when rotating to the highest position under the blocking of the inner limiting part, as shown in FIG. 4. Figure 3

[0041] In another embodiment of the present application, the bottom surface of the inner limiting part is a slope surface facing the lower side, and the side plate 130 is in an upwardly inclined state when rotating to the highest position under the blocking of the inner limiting part, as shown in FIG. 5. When the side plate 130 is inclined in this way, the horizontal height of the side plate 130 can be increased, thereby reducing the amount of accumulated water above the side plate 130 and reducing the pressure of the accumulated water on the side plate 130. Figures 5-6

[0042] In a possible embodiment, a partition 120 is arranged in the top frame, and the partition 120 divides the internal space of the top frame into two sub-frames, and each side plate 130 is used to block one sub-frame.

[0043] Exemplarily, the two ends of the partition 120 are respectively connected perpendicularly to the two side frames, and the partition 120 is located at the central position of the opening of the top frame, so that the two sub-frames formed are of the same size. After the partition 120 is arranged, the width of the sub-frame can be reduced, so that the side plate 130 only needs a smaller width to block the sub-frame, and moreover, the sub-frame formed also has the effect of intercepting large-sized impurities in the initial stage of water entering, thereby playing a role of preliminary filtering.

[0044] It should be understood that after the partition 120 is arranged, a sealing strip needs to be arranged at the edge of the partition 120 facing the side plate 130, so as to cooperate with the sealing strip at the end of the side plate 130, so that the side plate 130 is in a stable state when rotating to the highest position.

[0045] ​​After the partition 120 is set, the width of the sub-frame will be smaller than the width of the whole top frame opening, at this time when the filter screen 140 is installed, one end of the filter screen 140, preferably the end without the handle 141, is inserted into one sub-frame, while the filter screen 140 is continuously inserted, the filter screen 140 is gradually rotated in the horizontal direction until the whole filter screen 140 is inserted into the channel and is in a horizontal state.

[0046] In a possible embodiment, the side plate 130 is vertically rotated by a rotating shaft at the bottom of the top frame, a torsion spring is arranged on the rotating shaft, the torsion spring provides elastic force for upward rotation of the side plate 130.

[0047] Exemplarily, the torsion spring is sleeved on the rotating shaft, and two ends of the torsion spring are respectively abutted on the inner limiting part and the side plate 130, under the action of the elastic force provided by the torsion spring, the filter screen 140 can be tightly clamped, thereby avoiding sliding of the filter screen 140, and after the filter screen 140 is taken out, the side plate 130 can be upwardly rotated under the action of the elastic force, thereby being automatically rotated to the highest position, at this time under the action of the elastic force of the torsion spring and the pressure provided by the sealing strip, the side plate 130 can be stably arranged at the highest position and will not be opened due to the pressure of accumulated water.

[0048] Although the preferred embodiments of the present application have been described, those skilled in the art who are familiar with the basic inventive concept can make additional changes and modifications to the embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0049] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
