Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a drainage ditch. Background Art

[0002] A drainage ditch refers to a ditch that diverts the water collected from side ditches, intercepting ditches, and low-lying areas near roadbeds, farmlands, and residences to ditches outside the roadbeds, farmlands, and residences. The drainage ditch can be divided into an open ditch and a concealed ditch according to its construction location. Generally, the open ditch method is adopted in vast fields, while the concealed ditch method is adopted in cities, highway tunnels, water diversion channels, and both sides of some highways.

[0003] Generally, a permeable cover plate is laid on the concealed ditch to prevent pedestrians from falling or vehicles from tipping over. However, the existing permeable cover plates are generally directly placed on the concealed ditch. Due to the rolling of vehicles, they are prone to jumping, and in severe cases, the permeable cover plates will be separated from the concealed ditch; when there is waterlogging, the permeable cover plates are easily washed back by the water flow, resulting in the separation of the permeable cover plates from the concealed ditch. The separation of the permeable cover plate from the concealed ditch will pose a certain potential danger to pedestrians and vehicles.

[0004] The patent with the publication number CN212001498U discloses a drainage ditch, including a drainage ditch seat and a cover plate covering the drainage ditch seat. A receiving plate is arranged at the bottom of the drainage ditch seat, and drainage holes penetrating through the receiving plate are formed on the receiving plate. A plurality of pull handles are rotatably connected to both sides of the receiving plate. The above patent has the effect of faster cleaning efficiency of impurities in the drainage ditch. However, its cover plate is directly covered on the drainage ditch seat, which results in the cover plate being easily separated from the drainage ditch seat, thus posing a safety hazard to pedestrians and vehicles.

Specific embodiments

[0027] The core of the present utility model is to provide a drainage ditch, which can solve the defect that the cover plate of the drainage ditch is easily separated from the drainage ditch.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0030] In a specific embodiment of the present utility model, as Figures 1 to 8 shown, it includes a trough body 1, a cover plate 2 and an elastic member 3. A top plate 101 is integrally formed on the top of the trough body 1. A through hole 102 communicating with the inner cavity of the trough body 1 is opened on the top plate 101. Slide grooves are horizontally opened on two opposite side walls of the through hole 102. Two cover plates 2 are symmetrically arranged and block the through hole 102. One end of each of the two cover plates 2 away from each other is slidably inserted into the two slide grooves respectively. A number of elastic members 3 are arranged at intervals and in parallel between the slide grooves and the cover plates 2, and one end of the two cover plates 2 away from the slide grooves abuts against each other. A water permeable structure for leaking water is provided on the cover plate 2.

[0031] Specifically, the water permeable structure is used for water to flow into the trough body 1.

[0032] The cross-section of the trough body 1 is U-shaped. The through hole 102 is a long strip-shaped quadrilateral hole. The length direction of the quadrilateral hole is the axial direction of the trough body 1. The slide grooves are opened on the two long side walls of the through hole 102. The length and width dimensions of the cover plate 2 match the length and width dimensions of the quadrilateral hole. The depth of the slide groove is greater than or equal to the width dimension of the cover plate 2. The elastic member 3 is a compression spring. A first blind hole is horizontally opened on one side of each of the two cover plates 2 away from each other. One end of the compression spring abuts against the bottom wall of the first blind hole, and the other end of the compression spring abuts against the bottom wall of the slide groove.

[0033] Specifically, the pitch of the compression spring and the depth of the first blind hole can be determined by calculation or experimental methods to ensure that the cover plate 2 can completely enter the slide groove. For example, when the depth of the slide groove and the depth of the first blind hole are determined, compression springs with different pitches or wire diameters are used for experiments in turn, so as to select a compression spring that can ensure that the cover plate 2 completely enters the slide groove.

[0034] The water permeable structure includes water permeable holes 201, and a number of water permeable holes 201 are opened on the part of the cover plate 2 protruding out of the slide groove.

[0035] The water permeable structure includes notches 202 opened on the surfaces of the two cover plates 2 that abut against each other.

[0036] It also includes a filter plate 4, which is provided with a plurality of filter holes 401, and a plurality of ear plates 402 are spaced apart on both sides of the filter plate 4, and a protrusion 403 is provided on the bottom surface of the ear plate 402; the through hole 102 is used to provide an extension plate 103 on both side walls of the slide groove, and the extension plate 103 is integrally formed with the top plate 101, and the extension plate 103 is located below the cover plate 2, and a plurality of slots 104 corresponding to the ear plates 402 are provided on the top surface of the extension plate 103, and a groove 105 matching the protrusion 403 is provided on the bottom wall of the slot 104, and the ear plate 402 is snap-fitted with the slot 104, and the protrusion 403 is snap-fitted with the groove 105.

[0037] Specifically, in order to ensure the filtering effect of the filter plate 4, the interception capacity of the filter hole 401 should be greater than the water-permeable structure. This is a conventional technical means and will not be described in detail. Figure 1 As shown, the filter hole 401 is smaller than the water permeable hole 201 , and the filter hole 401 is smaller than the notch 202 .

[0038] It also includes a gear 5. The two wide side walls of each cover plate 2 are provided with a rack portion 203. Four second blind holes are opened on the top plate 101. The four second blind holes are respectively arranged corresponding to the four rack portions 203, and the bottom ends of the second blind holes are connected to the slide grooves. The four gears 5 are arranged one by one corresponding to the four second blind holes. The gear 5 is coaxially rotatable in the second blind hole, and the gear 5 is meshed with the rack portion 203. A regular hexagonal hole 501 is coaxially opened on the top surface of the gear 5.

[0039] Specifically, insert one end of an L-shaped hexagonal wrench into the regular hexagonal hole 501, and when the hexagonal wrench is turned, the gear 5 rotates synchronously, and the gear 5 drives the rack part 203 to move, and the cover plate 2 moves synchronously. In normal circumstances, the second blind hole can be blocked with a rubber plug to prevent mud and sand from entering.

[0040] It also includes threaded holes 6 opened on the top surface of the top plate 101 , and there are four threaded holes 6 , which are respectively located beside the four second blind holes.

[0041] Specifically, under normal circumstances, the threaded hole 6 can be sealed with a rubber plug to prevent mud and sand from entering.

[0042] The working principle of a drainage ditch of the utility model is as follows: Figure 2 As shown, the slide groove limits the front-to-back and up-down directions of the cover plate 2, and the elastic component 3 pushes the two cover plates 2 to abut against each other, so that the left-right directions of the cover plate 2 are limited. In summary, through the mutual constraints between the slide groove and the elastic component 3 and the two cover plates 2, the cover plate 2 will not move at will, and it is not easy to separate from the top plate 101, thereby ensuring the safety of pedestrians and vehicles.

[0043] Steps for opening the through-hole 102: First, fully insert one cover plate 2 into the chute, and then fully insert the other cover plate 2 into the chute, that is, operate the two gears 5 corresponding to one cover plate 2 simultaneously, so as to Figure 8 Taking the cover plate 2 on the left side as an example, one end of two hexagonal wrenches is respectively inserted into the regular hexagonal holes 501 of the two gears 5. The upper hexagonal wrench rotates clockwise, and the lower hexagonal wrench rotates counterclockwise, then the gear 5 rotates. The gear 5 drives the rack portion 203 to move, and then the cover plate 2 compresses the elastic member 3. Finally, the cover plate 2 fully enters the chute. Then, a bolt is threadedly connected to the threaded hole 6. According to Figure 8 the way shown, the other end of the hexagonal wrench abuts against the bolt, which can prevent the gear 5 from reversing and avoid the cover plate 2 sliding out of the chute under the thrust of the elastic member 3. Similarly, operate the other cover plate 2, and then the through-hole 102 is opened. After the through-hole 102 is opened, the impurities on the filter plate 4 can be cleaned, and the filter plate 4 can be taken out to clean the impurities in the tank body 1.

[0044] Steps for installing the cover plate 2: First, make the lug plate 402 of the filter plate 4 engage with the slot 104 and the convex block 403 engage with the groove 105 in the way shown in Figure 2 and 8 . Then, place the elastic member 3 into the chute, align the first blind hole of one cover plate 2 with the elastic member 3, and then slide the cover plate 2 into the chute. Then, make the cover plate 2 fully enter the chute in the way described in the steps for opening the through-hole 102. At this time, align the first blind hole of the other cover plate 2 with the elastic member 3 and align the cover plate 2 with the chute, that is, Figure 7 the state shown. Take out the hexagonal wrench, and the first installed cover plate 2 pushes the other cover plate 2 into the chute under the thrust of the elastic member 3.

[0045] Steps for disassembling the cover plate 2: Make one cover plate 2 fully enter the chute in the way described in the steps for opening the through-hole 102, then the other cover plate 2 slides out of the chute under the pushing action of the elastic member 3, that is, Figure 7 the state shown. Then take it out. Remove the hexagonal wrench, and the cover plate 2 located in the chute slides out of the chute under the pushing action of the elastic member 3, and then take it out.
