Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a rainwater drainage and anti-blocking device. Background Art

[0002] On municipal roads, it is usually necessary to install a grate at the inlet of the shaft. The grate is used to intercept larger-volume sundries mixed in rainwater and prevent larger-volume sundries from randomly entering the drainage pipeline and causing blockage. A plurality of uniformly arranged strip-shaped openings are formed in the grate. After the grate is installed, the part of the grate between adjacent strip-shaped openings lacks support. When a vehicle or the like walks on the grate, the part of the grate between adjacent strip-shaped openings is subjected to greater force. Over time, combined with the rust of the grate, the part of the grate between adjacent strip-shaped openings is easily deformed and damaged after being squeezed, affecting the service life of the grate. Therefore, it is necessary to design a rainwater drainage and anti-blocking device that improves the structural strength of the part of the grate between adjacent strip-shaped openings.

[0025] Reference Figures 1-5 , an embodiment of the present application shows a rain drainage and anti-blocking device, including a frame 1 for installation at the inlet part of the shaft. A limit frame 2 is provided on the upper surface of the frame 1. A grate plate 3 is inserted into the limit frame 2. A plurality of strip-shaped openings 4 that penetrate vertically and are arranged at equal horizontal intervals are formed on the grate plate 3. A plurality of laterally penetrating insertion holes 6 are formed on the side surface of the frame 1. An insertion rod 5 is inserted into the insertion hole 6. Both ends of the insertion rod 5 extend to the outside of the frame 1. A vertically arranged rod column 19 is provided in the area of the insertion rod 5 below the grate plate 3. The rod column 19 abuts against the bottom of the grate plate 3 and corresponds to the position between two strip-shaped openings 4.

[0026] Among them, the insertion rod 5 is inserted into the insertion hole 6, and both ends of the insertion rod 5 are buried in the formation. After the grate plate 3 is placed in the limit frame 2, the rod column 19 is in contact with the lower surface of the grate plate 3. At this time, the structure formed by the insertion rod 5 and the rod column 19 realizes the support for the part of the grate plate 3 between two adjacent strip-shaped openings 4, improving the structural strength of the part of the grate plate 3 between two adjacent strip-shaped openings 4; in addition, both ends of the insertion rod 5 extend to the outside of the frame 1 and are buried in the formation, so that the extrusion force received by the insertion rod 5 is dispersed to the formation, reducing the extrusion degree on the shaft wellhead part.

[0027] In some embodiments, as Figure 3 and Figure 5 shown, an installation hole 20 is formed on the insertion rod 5. The lower end of the rod column 19 is fixed in the installation hole 20. Among them, first insert the insertion rod 5 into the insertion hole 6, and then install the rod column 19 in the installation hole 20 to avoid interference of the rod column 19 when the insertion rod 5 is horizontally inserted into the insertion hole 6;

[0028] Further preferably, for the convenience of installation, the installation hole 20 is in threaded connection with the rod column 19.

[0029] In some embodiments, in order to enable the insertion rod 5 to better disperse the pressure received to the formation, as Figure 1 and Figure 2As shown in the figure, extension rods 7 are provided at both ends of the insertion rod 5. Among them, the lengths of both ends of the insertion rod 5 are extended by using the extension rods 7, so that the range where the insertion rod 5 is erected on the bottom layer is larger; it should be noted that the number of the extension rods 7 provided can be multiple, so as to increase the lengths of both ends of the insertion rod 5 to an appropriate length, which is convenient for adaptive adjustment for different hardness of strata, ensuring that the insertion rod 5 can better disperse the pressure it bears, and improving the bearing stability of the rainwater drainage and anti-blocking device when bearing pressure.

[0030] Specifically, the above solution is as follows Figure 1 and Figure 2 As shown in the figure, a first socket 10 arranged axially is opened at the end of the insertion rod 5, a first plug 15 arranged axially is provided at one end of the extension rod 7, a second socket 17 arranged axially is provided at the other end of the extension rod 7, a first pin hole 13 penetrating radially is opened on the insertion rod 5, and the first pin hole 13 communicates with the first socket 10; a second pin hole 14 penetrating radially is opened on the first plug 15, a third pin hole 16 penetrating radially is also opened on the insertion rod 5, and the third pin hole 16 communicates with the second socket 17; a pin rod 12 is further included, and the pin rod 12 is inserted into the first pin hole 13 and the second pin hole 14, or / and the pin rod 12 is inserted into the second pin hole 14 and the third pin hole 16.

[0031] Among them, when it is necessary to add an extension rod 7 to the end of the insertion rod 5, the first plug 15 of the extension rod 7 is inserted into the first socket 10 at the end of the insertion rod 5, and then the pin rod 12 is inserted into the first pin hole 13 and the second pin hole 14, so that the first plug 15 cannot be separated from the first socket 10; when it is necessary to add multiple extension rods 7, the first plug 15 of one extension rod 7 can be inserted into the second socket 17 of another extension rod 7, and then the pin rod 12 is inserted into the second pin hole 14 and the third pin hole 16, so that the first plug 15 cannot be separated from the second socket 17, thus completing the connection between the two extension rods 7; in this embodiment, it is convenient to flexibly extend the length of the end of the insertion rod 5, with simple operation and stable structure.

[0032] In some embodiments, to further improve the connection stability between the insertion rod 5 and the soil layer, as shown in Figure 1 and Figure 2 the figure, a positioning plug-in is further included, the positioning plug-in includes a rod body 8, a limiting block 9 is fixedly connected to one end of the rod body 8, and a pointed structure is provided at the other end; a first positioning hole 11 for inserting the positioning plug-in is vertically penetrated on the part of the insertion rod 5 extending outside the frame 1.
