Description

Technical Field

[0001] This utility model relates to the field of basement drainage components and drainage structures, and in particular to a basement anti-clogging grate and basement drainage structure. Background Technology

[0002] A basement drainage ditch is a drainage structure used to drain water from basements, prevent flooding, and keep the basement dry. Floodwater in the basement flows into the drainage ditch, which then guides the water into a sump. When the floodwater flows into the drainage ditch, it often carries sand, gravel, and other foreign objects. Over time, more and more of these foreign objects settle in the drainage ditch, causing blockages in certain sections, leading to overflow and preventing the drainage system from draining the water.

[0003] Currently, to prevent drainage ditch blockage, grates are installed at the top opening of the drainage ditch. These grates physically filter and prevent larger foreign objects from entering the drainage ditch. For specific details, refer to the technical solution of patent application number 202021274627.3, which discloses a drainage layer for preventing seepage in basement slabs, including a pebble filter layer. This pebble filter layer is laid on the upper surface of the foundation slab, and a fine aggregate concrete surface layer is poured on the upper surface of the pebble filter layer through a colored strip isolation layer. A drainage ditch connected to a sump is provided. A cast iron grate is installed on the top of the drainage ditch via angle steel supports. When the drainage ditch is adjacent to a concrete wall foundation, one side of the drainage ditch is connected to the concrete wall foundation via a brick support, and a concrete cutting platform is provided on the other side. When the drainage ditch is not adjacent to a concrete wall foundation, concrete cutting platforms are provided on both sides of the drainage ditch, and steel reinforcement tie members are installed in the concrete cutting platforms. One end of the steel reinforcement tie members extends out of the concrete cutting platform. A drainage pipe is embedded in the concrete cutting platform. One end of the drainage pipe extends to the pebble filter layer, and the other end extends to the drainage ditch.

[0004] The above-mentioned solution only uses cast iron grates for preliminary filtration, which cannot prevent small foreign objects from settling in the drainage ditch. The drainage ditch is very easy to get clogged. When the drainage ditch is clogged, it cannot drain the water, which can easily breed mosquitoes and cause the water in the drainage ditch to overflow onto the basement floor, which can easily cause pedestrians to slip and fall or get wet from vehicles. Utility Model Content

[0005] The purpose of this utility model is to provide a basement anti-blockage grate and basement drainage structure to facilitate the drainage of water blocked by settled foreign objects in certain sections of the drainage ditch, thus preventing the inability to drain water normally.

[0006] The technical solution provided by this utility model is as follows: a basement anti-blockage grate, including a grate body, a drainage hole on the grate body, a partition plate for dividing the inner cavity of the drainage ditch into two flow channels fixedly connected to the bottom of the grate body, the drainage hole being located on one side of the partition plate, and a plurality of movable plates that can swing up and down around the hinge fulcrum being hinged to the opposite side of the partition plate, the movable plates being arranged at intervals along the length direction of the partition plate, and a drainage hole corresponding to each movable plate being opened on the partition plate, the drainage hole being located directly below the hinge fulcrum;

[0007] When the movable plate is in the first working state, the side of the movable plate adjacent to the partition is in contact with the partition to close the drainage hole; when the movable plate is in the second working state, the movable plate and the partition form an angle so that the drainage hole can connect the opposite sides of the partition.

[0008] In the aforementioned basement anti-blocking grate, each of the drainage holes is provided with a connecting component corresponding to the movable plate. The connecting component includes a pair of connecting blocks located on opposite sides of the corresponding movable plate. The outer side of the connecting block is fixedly connected to the side of the partition adjacent to the movable plate. The connecting block has an inner cavity facing the opening of the corresponding movable plate. A connecting shaft is fixedly connected to the top of the movable plate. The two ends of the connecting shaft pass through the inner cavity of the adjacent two openings and are rotatably engaged with the inner cavity.

[0009] In the aforementioned basement anti-blocking grate, the inner cavity extends through the top of the connecting block to allow the connecting shaft to be inserted and removed vertically.

[0010] In the aforementioned basement anti-blocking grate, a buffer strip is connected to the movable plate. The buffer strip has a first side wing, which abuts against the side of the movable plate near the partition. The buffer strip extends along the edge of the movable plate from one side of the top of the movable plate to the other side of the top of the movable plate and is fixed to the movable plate.

[0011] In the aforementioned basement anti-blocking grate, the buffer strip is provided with a second side wing, and the edge of the movable plate is sandwiched between the first side wing and the second side wing.

[0012] The basement drainage structure includes side walls, a floor slab, and a floor laid on the floor slab. A drainage ditch is provided between the side walls and the floor. The top of the drainage ditch is provided with several basement anti-clogging grates arranged side by side along its extension direction, as described above. The top surface of the grate body is not higher than the top surface of the floor. One side of the grate body is connected to the inner side of the side wall, and the opposite side is connected to the side of the floor adjacent to the side wall. A partition is provided in the drainage ditch. The length direction of the partition is the same as the extension direction of the drainage ditch, and it abuts against the bottom of the drainage ditch.

[0013] In the aforementioned basement drainage structure, the drainage hole is located between the partition and the floor.

[0014] In the aforementioned basement drainage structure, the floor gradually decreases from the side away from the drainage ditch to the side adjacent to the drainage ditch, and the upper surface of the grate is not higher than the edge of the lower side of the base plate.

[0015] In the aforementioned basement drainage structure, a positioning groove extending along its extension direction is provided at the bottom of the drainage ditch, and the lower side of the partition is inserted into the positioning groove.

[0016] In the above-mentioned basement drainage structure, each of the side walls and the floor adjacent to each other is provided with a protrusion fixedly connected to the base plate. The protrusions on both sides are spaced apart, and the protrusions on both sides and the base plate together enclose the drainage ditch. The top surface of the protrusions on both sides abuts against the bottom of the grate body.

[0017] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0018] This solution uses a partition on the grate body to divide the inner cavity of the drainage ditch into two channels, both of which can connect to a collection well. Floodwater from the basement falls into the first channel of the drainage ditch through the drainage holes. Foreign objects carried by the floodwater also enter the first channel and settle there. As the settled foreign objects accumulate, they obstruct the water flow, forcing the water to change direction and pushing a movable plate. This causes the movable plate, which closes the drainage hole, to swing upwards, forming an angle between the movable plate and the partition. At this point, the drainage hole connects the two channels, allowing the water in the first channel to enter the second channel and then drain into the collection well. This effectively drains water blocked by settled foreign objects in certain sections of the drainage ditch, preventing any disruption to normal drainage. Attached Figure Description

[0030] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.

[0031] Example 1:

[0032] like Figure 1-7 As shown, a basement anti-blockage grate 5 includes a grate body 51, on which drainage holes 511 are provided. A partition plate 52 for dividing the inner cavity of the drainage ditch 14 into two flow channels is fixedly connected to the bottom of the grate body 51. The drainage holes 511 are located on one side of the partition plate 52. Several movable plates 6 that can swing up and down around the hinge point are hinged to the opposite side of the partition plate 52. The movable plates 6 are arranged at intervals along the length of the partition plate 52. The partition plate 52 has drainage holes 521 that correspond one-to-one with the movable plates 6. The drainage holes 521 are located directly below the hinge point.

[0033] When the movable plate 6 is in the first working state, the side of the movable plate 6 adjacent to the partition 52 is in contact with the partition 52 to close the drainage hole 521; when the movable plate 6 is in the second working state, the movable plate 6 forms an angle with the partition 52 so that the drainage hole 521 can connect the opposite sides of the partition 52.

[0034] Its working principle is as follows: a partition 52 is installed on the grate body 51, and the grate body 51 is placed at the upper opening of the drainage ditch 14, so that the partition 52 located at the bottom of the grate body 51 is inside the drainage ditch 14, and the bottom of the partition 52 abuts against the bottom of the drainage ditch 14. The partition 52 extends along the length of the drainage ditch 14, dividing the inner cavity of the drainage ditch 14 into two flow channels, both of which can be connected to a water collection well. The drain hole 511 on the grate body 51 for the accumulated water to fall into the drainage ditch 14 is located on one side of the partition 52. The drain hole 511 is located directly above one of the flow channels. Water containing foreign objects first falls through the drain hole 511 into the flow channel of the drainage ditch 14 and settles there. A guide hole 521 is provided on the partition 52. A movable plate 6 is hinged to the side of the partition 52 away from the drain hole 511. Under gravity alone, the movable plate 6 fits against the corresponding side of the partition 52 and seals the guide hole 521, preventing water containing foreign objects from flowing into the second flow channel and thus preventing the foreign objects from entering the second flow channel. Settling occurs only in the first channel to prevent foreign objects from clogging the second channel. When foreign objects settle in the first channel and block it, they create resistance along the length of the channel, forcing the water to flow to both sides of the channel's width. The water on the width side impacts the movable plate 6 through the drainage hole 521, increasing the force on the movable plate 6 and pushing it open. An angle is formed between the movable plate 6 and the partition 52, at which point the drainage hole 521 connects the two channels. The water in the first channel enters the second channel through the drainage hole 521 and is discharged into the collection well via the second channel. When the water flow slows down or stops, the movable plate 6 re-closes the drainage hole 521. Through the cooperation of the above structure and mechanism, blockage of the drainage ditch 14 section only occurs in the first channel. When the first channel is blocked, it can be cleared through the second channel, greatly reducing the frequency and workload of later maintenance and cleaning. This achieves the clearing of water blocked by settled foreign objects in the drainage ditch 14 section, preventing the inability to properly drain water.

[0035] Combination Figure 2 and Figure 4As shown, the specific hinged connection between the movable plate 6 and the partition 52 is as follows: each of the drainage holes 521 is provided with a connecting component corresponding to the movable plate 6. The connecting component includes a pair of connecting blocks 522 located on opposite sides of the movable plate 6. The outer side of the connecting block 522 is fixedly connected to the side of the partition 52 adjacent to the movable plate 6. The connecting block 522 has an inner cavity facing the opening of the movable plate 6. A connecting shaft 62 is fixedly connected to the top of the movable plate 6. The two ends of the connecting shaft 62 pass through the inner cavity of the adjacent two sides of the opening and are rotatably engaged with the inner cavity.

[0036] In some embodiments, the connecting blocks 522 on both sides are first sleeved on both ends of the connecting shaft 62, and then the connecting blocks 522 are fixed on the side of the partition 52 near the movable plate 6 by welding, bolt connection or other means.

[0037] In a further improvement, the inner cavity extends through the top of the connecting block 522 to allow the connecting shaft 62 to be inserted and removed vertically.

[0038] The inner cavity extends through the top of the connecting block 522, forming an installation port on the top of the connecting block 522. The end of the connecting shaft 62 can be installed in the inner cavity through the installation port. When the connecting shaft 62 is taken out of the inner cavity, the movable plate 6 is lifted upwards, which allows the connecting shaft 62 to detach from the connecting block 522 through the installation port. There is no need to disassemble the connecting block 522, thus achieving quick loading and unloading.

[0039] In this embodiment, the connecting block 522 is specifically a hook. One end of the hook is fixedly connected to the side of the partition 52 near the movable plate 6, and the other end is bent and extended upward. The two ends of the hook are spaced apart to form the inner cavity.

[0040] like Figure 6 As shown, in another improvement of this embodiment, a buffer strip 61 is connected to the movable plate 6. The buffer strip 61 is provided with a first side wing 611. The first side wing 611 abuts against the side of the movable plate 6 near the partition 52. The buffer strip 61 extends along the edge of the movable plate 6 from one side of the top of the movable plate 6 to the other side of the top of the movable plate 6 and is fixed to the movable plate 6.

[0041] The first side wing 611 is designed to prevent the movable plate 6 from directly colliding with the partition 52, thereby reducing noise, reducing wear on the movable plate 6 and the partition 52, preventing the movable plate 6 from deforming under stress, and extending its service life. Specifically, when the movable plate 6 swings from top to bottom, due to the inertia of motion, the side of the movable plate 6 adjacent to the partition 52 will collide with the partition 52, generating noise and affecting the service life of both the partition 52 and the movable plate 6. The buffer strip 61 is fixed to the movable plate 6, and the first side wing 611 on the buffer strip 61 abuts against the side of the movable plate 6 adjacent to the partition 52. The buffer strip 61 and the first side wing 611 extend together along the edge of the movable plate 6. The first side wing 611 covers the horizontal sides and the bottom of the movable plate 6, preventing the movable plate 6 from rigidly colliding with the partition 52. When the opposite sides of the first side wing 611 are subjected to the collision pressure of the partition 52 and the movable plate 6, they can be cushioned by their own material properties.

[0042] Combination Figure 5 and Figure 6 As shown, preferably, the buffer strip 61 is provided with a second side wing 612, and the edge of the movable plate 6 is sandwiched between the first side wing 611 and the second side wing 612.

[0043] The specific fixing method of the buffer strip 61 is as follows: the first side wing 611 and the second side wing 612 on the buffer strip 61 clamp the movable plate 6. There is frictional resistance between the first side wing 611 and the movable plate 6, and between the second side wing 612 and the movable plate 6. Without external force, the buffer strip 61 can be stably fixed on the movable plate 6. By applying external force to pull the buffer strip 61, the buffer strip 61 can be pulled off the movable plate 6, which has the advantages of quick installation and removal, and is convenient for replacement and maintenance.

[0044] In this embodiment, the buffer strip 61, the first sidewall 11, and the second sidewall 11 are specifically made of PVC material, but can also be replaced by materials such as rubber. This embodiment does not impose too many restrictions on this.

[0045] Example 2:

[0046] like Figure 1-7 As shown, the basement drainage structure includes a side wall 11, a base slab 12, and a floor 13 laid on the base slab 12. A drainage ditch 14 is provided between the side wall 11 and the floor 13. The top of the drainage ditch 14 is provided with several basement anti-blocking grates 5 arranged side by side along its extension direction, as described in Embodiment 1. The top surface of the grate body 51 is not higher than the top surface of the floor 13. One side of the grate body 51 is connected to the inner side of the side wall 11, and the opposite side is connected to the side of the floor 13 adjacent to the side wall 11. A partition 52 is provided in the drainage ditch 14. The length direction of the partition 52 is the same as the extension direction of the drainage ditch 14, and it abuts against the bottom of the drainage ditch 14.

[0047] like Figure 2 As shown, preferably, the drain hole 511 is located between the partition 52 and the floor 13.

[0048] The drainage hole 511 is positioned so that it is located on the side of the grate body 51 closest to the floor 13. Water from the basement 1 enters the grate body 51 from one side and can quickly fall into the drainage ditch 14 through the drainage hole 511 without having to cross from one side of the grate body 51 to the other side before falling into the drainage ditch 14 through the drainage hole 511, thus improving the water intake and drainage efficiency of the drainage ditch 14.

[0049] like Figure 1 As shown, preferably, the floor 13 gradually decreases from the side away from the drain ditch 14 to the side adjacent to the drain ditch 14, and the upper surface of the grate is not higher than the edge of the lower side of the base plate 12.

[0050] The upper surface of the floor 13 is designed so that the water on the ground of the basement 1 flows automatically to the top of the grate body 51 under the action of gravity, and falls into the first channel of the drainage ditch 14 through the drainage hole 511.

[0051] like Figure 2 As shown, preferably, the bottom of the drainage ditch 14 is provided with a positioning groove 121 extending along its extension direction, and the lower side of the partition 52 is inserted into the positioning groove 121.

[0052] The positioning groove 121 is set to install and position the partition 52, so that each adjacent partition 52 is within the straightness error range, thereby improving the separation effect of several partitions 52 in the drainage ditch 14.

[0053] In this embodiment, the sidewall 11 and the floor 13 are each provided with a protrusion 7 fixedly connected to the base plate 12 on their adjacent sides. The protrusions 7 on both sides are spaced apart. The protrusions 7 on both sides and the base plate 12 together enclose the drainage ditch 14. The top surface of the protrusions 7 on both sides abuts against the bottom of the grate body 51.

[0054] In addition, a mixing pile 4 and a diaphragm wall 3 are provided on the outer side of the side wall 11, and a roll material layer 2 is laid on the outer side of the side wall 11 between the diaphragm wall 3 and the side wall 11.

[0055] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
