Description

Technical Field

[0001] This application relates to the field of drainage devices, and more particularly to a drainage ditch. Background Technology

[0002] Drainage ditches are ditches that direct water collected in side ditches, intercepting ditches, and low-lying areas near roadbeds, farmland, and residences to areas outside the roadbed, farmland, and residences.

[0003] For example, the utility model patent with patent publication number CN207453055U discloses an L-shaped drainage ditch, including a cover plate and a trough. The trough includes a horizontal trough and a vertical trough. The end of the vertical trough is vertically connected to the horizontal trough to form an L-shape. The trough is integrally formed. There are two cover plates, which are respectively covered on the top of the horizontal trough and the vertical trough. It has good water flow performance, shock resistance, pressure resistance and long service life.

[0004] When using the L-shaped drainage ditch, the installer needs to carry a screwdriver with them when installing the cover plate. If the screwdriver is accidentally forgotten, it will affect the installation of the drainage ditch, which is inconvenient and needs to be improved. Summary of the Invention

[0005] To address the issue that forgetting a screwdriver during the installation of a drainage ditch can affect the installation of the drainage ditch, this application provides a drainage ditch.

[0006] The drainage ditch provided in this application adopts the following technical solution:

[0007] A drainage ditch includes a cover plate and a trough. The cover plate has filter holes, and a collar is slidably connected to the trough. The collar slides closer to or away from the cover plate and is rotatably connected to the trough. The cover plate has a connecting block, and the connecting block has a locking block. The collar has a notch for the connecting block and the locking block to engage. The collar also has a clearance groove communicating with the notch. The clearance groove is located on the side of the notch away from the cover plate, and the clearance groove is for the locking block to engage.

[0008] A plug is slidably connected to the cover plate. The plug slides closer to or away from the connecting block. An elastic element is also provided on the cover plate. The elastic element abuts against the plug, so that the plug tends to move closer to the connecting block. A slot is provided on the collar for the plug to be inserted. When the plug is inserted into the slot, the insert abuts against the inner wall of the bottom of the relief groove.

[0009] By adopting the above technical solution, when the cover plate needs to be installed, the cover plate is placed on the groove, and then the collar is moved close to the cover plate until the connecting block and the locking block are both engaged in the notch and the locking block is located in the relief groove. The collar is rotated so that the locking block and the notch are misaligned and the insert block and the slot are aligned. At this time, the insert block slides close to the connecting block and engages in the slot under the action of the elastic element. The insert block abuts against the inner wall of the slot and the locking block abuts against the inner wall of the bottom of the relief groove, suppressing the slippage and rotation of the collar and realizing the positioning of the collar. The collar abuts against the groove and the connecting block, realizing the installation of the cover plate on the groove. There is no need to use screwdrivers or other installation tools, reducing the trouble caused by forgetting installation tools. Compared with threaded connection, the operation time is shorter, which helps to improve the installation efficiency of drainage ditch.

[0010] Optionally, the locking block includes a fixing block disposed on the connecting block and a threaded sleeve threadedly connected to the fixing block. The connecting block is rotatably connected to the cover plate. The insert block has a slot for the threaded sleeve to be inserted. When the threaded sleeve is inserted into the slot, the connecting block, the locking block and the insert block are spliced ​​to form a limiting groove. When the cover plates are stacked vertically, the limiting groove allows the threaded sleeves on adjacent cover plates to be inserted.

[0011] By adopting the above technical solution, when transporting the cover plate, the connecting block is rotated so that the threaded sleeve faces the slot, and then the insert block is released so that the threaded sleeve is inserted into the slot to form a limiting groove. Then, the cover plates are stacked together vertically, and the threaded sleeve on the cover plate at the top is twisted so that the threaded sleeve is inserted into the slot. The threaded sleeve abuts against the inner wall of the slot, thereby achieving the limiting of the cover plates in the same stack, reducing the possibility of the cover plates slipping and being damaged during transportation, and helping to reduce the damage rate of the cover plates.

[0012] Optionally, the fixing block includes a fixing part disposed on the connecting block, a hinge part hinged to the fixing part, an elastic element two disposed on the hinge part, and an arc-shaped strip. The threaded sleeve is threadedly connected to the fixing part. The hinge part flips to move closer to or away from the fixing part. The fixing part has an installation groove. The hinge part is located in the installation groove. The elastic element two abuts against the fixing part, so that the hinge part has a tendency to flip away from the fixing part. The arc-shaped strip is located at the end of the hinge part away from the hinge axis and protrudes in a direction away from the connecting block. When the threaded sleeve is inserted into the limiting groove, the arc-shaped strip is used to abut against the end of the threaded sleeve away from the limiting groove.

[0013] By adopting the above technical solution, when the threaded sleeve is inserted into the limiting groove, the hinge part, under the action of the second elastic element, drives the arc-shaped strip to extend out of the fixed part. The arc-shaped strip abuts against the threaded sleeve, so that the threaded sleeve and the thread on the fixed part are tightly abutted, thereby reducing the possibility of the threaded sleeve loosening under the shaking caused by the movement of the transport vehicle. In addition, the hinge part can abut against the adjacent cover plate to buffer the cover plate, thereby reducing the possibility of collision between adjacent cover plates under shaking, which helps to further reduce the damage rate of the cover plate during transportation. When installing the cover plate, the hinge part is flipped so that the hinge part is inserted into the installation groove, and then the threaded sleeve is twisted so that the threaded sleeve covers the installation groove. Under the action of the second elastic element, the hinge part abuts against the threaded sleeve, so that the threaded sleeve and the thread on the fixed part are tightly abutted, suppressing the loosening between the collar and the locking block, thereby reducing the possibility of the threaded sleeve coming off and improving the installation stability of the cover plate on the groove.

[0014] Optionally, the groove is provided with a limiting block, and the notch is for the limiting block to pass through. The limiting block is used to abut against the side of the collar near the cover plate.

[0015] By adopting the above technical solution and setting a limiting block, when the transport tank is being transported, the moving collar causes the limiting block to pass through the notch. Then, the collar is rotated so that the limiting block abuts against the side of the collar near the cover plate, which can limit the collar and reduce the possibility of the collar coming off the tank during transportation.

[0016] Optionally, a baffle is slidably connected to the cover plate, and a sliding groove is provided on the groove body for the baffle to be engaged, the sliding groove being located above the collar.

[0017] By adopting the above technical solution and setting up a baffle, after the trough and cover plate are installed, the baffle is moved and inserted into the sliding groove. The baffle covers the collar, connecting block, insert block and locking block to reduce the situation where soil, garbage and other debris bury the insert block or collar. This makes it easier to disassemble and replace the damaged cover plate by moving the insert block and rotating the collar if the cover plate is damaged in the future.

[0018] Optionally, the trough body is further provided with a clearance cavity, which is located below and communicates with the slide groove. The trough body is provided with a support rod, which is located at the end of the clearance cavity near the cover plate and abuts against the baffle. A bracket is provided on the cover plate for vertical sliding, and a protrusion is provided on the bracket. The protrusion is located below the cover plate and is used to pass through the filter holes. A slide rail is provided on the baffle plate along its length direction. A movable ball is provided on the bracket and is located in the slide rail. The bracket and the cover plate are spliced ​​to form a water passage, which communicates with the filter holes.

[0019] By adopting the above technical solution, when the filter holes are blocked by garbage, the baffle can be moved towards the cover plate until the baffle is disengaged from the bottom of the chute. Then, the part of the baffle located on the hinge shaft away from the threaded part is stepped on, causing the part of the baffle located on the hinge shaft near the threaded sleeve to lift up, driving the bracket to move upward, so that the protrusion passes through the filter hole, thereby pushing out the garbage in the filter hole. The staff only needs to sweep the garbage pushed out of the cover plate to clean the cover plate, without having to clean the filter holes on the cover plate one by one, making the cleaning of the filter plate more convenient and more efficient. When the drainage ditch is in use, the baffle is reset, driving the bracket to move downward, so that the protrusion disengages from the filter hole, and the water accumulated on the cover plate can be discharged through the filter hole and the water passage.

[0020] Optionally, the bracket is provided with an elastic element three, which abuts against the cover plate, causing the bracket to have a downward tendency.

[0021] By adopting the above technical solution and setting up elastic element three, the cover plate is pressed by elastic element three, so that the baffle is pressed against the inner wall of the slide groove, increasing the friction between the baffle and the inner wall of the slide groove, thereby reducing the situation where the baffle is dislodged from the limiting groove due to shaking, which helps the baffle to stably perform its blocking function.

[0022] Optionally, the groove is provided with a limiting plate, which is located above the slide groove and is used to abut against the baffle.

[0023] By adopting the above technical solution and setting a limiting plate, when the baffle is disengaged from the chute, the limiting plate abuts against the baffle to limit the baffle, thereby reducing the situation where the baffle tilts up under the action of the elastic element three, and the tilting angle is too large, making it difficult for workers to step on the baffle. On the other hand, when pedestrians pass through the drainage ditch, the limiting plate provides support to reduce the contact between the baffle and the pedestrians, thereby reducing the damage to the baffle after being stepped on by pedestrians multiple times, which is conducive to extending the service life of the baffle.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When the cover plate needs to be installed, place the cover plate on the groove, move the collar closer to the cover plate, and then rotate the collar so that the locking block and the notch are misaligned and the insert block and the slot are aligned. At this time, the insert block is locked into the slot under the action of the elastic element, which can realize the positioning of the collar. The collar abuts against the groove and the connecting block to realize the installation of the cover plate on the groove. No screwdriver or other installation tools are needed, which reduces the trouble caused by forgetting installation tools and helps to improve the installation efficiency of the drainage ditch.

[0026] 2. After the threaded sleeve is inserted into the limiting groove, the arc-shaped strip extends out of the fixing part and abuts against the threaded sleeve to reduce the possibility of the threaded sleeve loosening during transportation. The hinge part can abut against the adjacent cover plate to buffer the cover plate and reduce the possibility of collision between the adjacent cover plates under shaking, which helps to reduce the damage rate of the cover plate during transportation. When the cover plate is installed, the threaded sleeve covers the installation groove, and the hinge part abuts against the threaded sleeve under the action of the elastic element II, suppressing the loosening between the collar and the locking block and improving the installation stability of the cover plate on the groove.

[0027] 3. When the filter holes are clogged with debris, move the baffle closer to the cover plate until it disengages from the bottom of the chute. Then, step on the part of the baffle located on the hinge shaft away from the threaded part, causing the part of the baffle located on the hinge shaft near the threaded sleeve to lift up. This moves the bracket upward, allowing the protrusion to pass through the filter holes and push out the debris. Workers only need to sweep the debris that has been pushed out of the cover plate to clean it, making cleaning the filter plate more convenient and efficient. Attached Figure Description

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0040] This application discloses a drainage ditch. See also... Figure 1 The drainage ditch includes a cover plate 1 and a trough 2. The upper surface of the cover plate 1 is provided with a number of filter holes 11. The filter holes 11 are spaced apart from each other, and each filter hole 11 penetrates the cover plate 1 vertically.

[0041] See Figure 2 and Figure 3 The trough 2 includes a main body 21 and several extension rods 22. The upper end face of the main body 21 is provided with a receiving groove 211 for the cover plate 1 to be inserted. Several grooves 212 are provided on the inner side wall of the receiving groove 211. The grooves 212 are located on opposite sides of the receiving groove 211. The grooves 212 on the same side of the receiving groove 211 are evenly spaced along the length of the main body 21. The number and position of the grooves 212 on both sides of the receiving groove 211 correspond one-to-one. Each groove 212 penetrates the trough upwards.

[0042] See Figure 3 The number of extension rods 22 is twice the number of grooves 212. Every two extension rods 22 are fixed to the inner wall of the bottom of the same groove 212 and are set towards the cover plate 1 in the receiving groove 211. Both extension rods 22 are set horizontally.

[0043] See Figure 3A collar 3 is slidably connected to the extension rod 22. The collar 3 slides closer to or away from the cover plate 1 in the receiving groove 211. The number and position of the collar 3 correspond one-to-one with the number and position of the groove 212. Two arc-shaped holes 31 are opened on the outer wall of the collar 3. Both arc-shaped holes 31 pass through the collar 3 along the sliding direction of the collar 3. The position of the two arc-shaped holes 31 corresponds one-to-one with the position of the two extension rods 22 in the groove 212. Each extension rod 22 passes through the corresponding arc-shaped hole 31 and slides relative to the collar 3 and is connected to the arc-shaped hole 31. The collar 3 is rotatably connected to the main body 21 through the cooperation with the extension rod 22, and the rotation axis of the collar 3 is parallel to its sliding direction. The two arc-shaped holes 31 are located on opposite sides of the rotation axis of the collar 3.

[0044] See Figure 4 and Figure 5 A notch 32 is provided on the outer peripheral wall of the collar 3, and the notch 32 penetrates the collar 3 along the sliding direction of the collar 3. A clearance groove 33 is also provided on the outer side wall of the collar 3 away from the cover plate 1, and the clearance groove 33 is located away from the notch 32 from the cover plate 1 (see Figure 3 ) on one side and connected to gap 32.

[0045] See Figure 4 Limiting blocks 4 are fixed on the inner wall of the bottom of the receiving groove 211. The number and position of the limiting blocks 4 correspond one-to-one with the number and position of the extension rods 22. The notch 32 allows the limiting blocks 4 to pass through. The limiting blocks 4 are used to abut against the collar 3 near the cover plate 1 (see Figure 3 ( ) on one side.

[0046] In practical use, when transporting the tank 2, the collar 3 is moved away from the cover plate 1 so that the limiting block 4 passes through the notch 32. Then, the collar 3 is rotated so that the limiting block 4 and the notch 32 are misaligned and the limiting block 4 abuts against the side of the collar 3 near the cover plate 1, thus limiting the collar 3. The collar 3 is positioned on the tank 2 by the frictional resistance between it and the limiting block 4, so as to reduce the possibility of the collar 3 falling off the tank 2 during transportation.

[0047] See Figure 3 and Figure 6 A connecting block 5 is rotatably connected to the cover plate 1. The number and position of the connecting block 5 correspond one-to-one with the number and position of the extension rod 22. When the cover plate 1 is located in the receiving groove 211, the rotation axis of the connecting block 5 coincides with the rotation axis of the corresponding collar 3, and the connecting block 5 is positioned on the cover plate 1 by the frictional resistance between it and the cover plate 1.

[0048] See Figure 6 and Figure 7The connecting block 5 is provided with a locking block 6, which includes a fixing block 61 and a threaded sleeve 62. The fixing block 61 includes a fixing part 611, a hinge part 612, an elastic element 613, and an arc-shaped strip 614. The fixing part 611 is fixed to the connecting block 5 and the corresponding extension rod 22 (see...). Figure 3 On the adjacent side, an installation groove 6111 is provided on the outer wall of the fixing part 611. The threaded sleeve 62 is located on the side of the installation groove 6111 away from the connecting block 5, and the threaded sleeve 62 is sleeved on the outside of the fixing part 611 and threadedly connected to the fixing part 611.

[0049] See Figure 6 and Figure 7 The hinge portion 612 is located in the mounting groove 6111 and hinged to the fixing portion 611. The hinge axis of the hinge portion 612 is perpendicular to the rotation axis of the connecting block 5 and is horizontally arranged. The hinge portion 612 flips to move closer to or away from the fixing portion 611. The elastic element 613 is installed and fixed on the hinge axis of the hinge portion 612. The elastic element 613 abuts against the fixing portion 611, so that the hinge portion 612 has a tendency to flip away from the fixing portion 611. In this embodiment, the elastic element 613 is a torsion spring.

[0050] See Figure 6 and Figure 7 The arc-shaped strip 614 is located at the end of the hinge portion 612 away from the hinge axis and on the side of the hinge portion 612 near the bottom of the mounting groove 6111. The arc-shaped strip 614 protrudes away from the connecting block 5 and is fixed on the hinge portion 612. The notch 32 is for the connecting block 5 and the locking block 6 to be inserted, and the clearance groove 33 is for the locking block 6 to be inserted.

[0051] See Figure 6 A plug 7 is slidably connected to the cover plate 1. The number and position of the plug 7 correspond one-to-one with the number and position of the connecting block 5. The plug 7 slides closer to or away from the corresponding connecting block 5. An elastic element 8 is also fixed on the cover plate 1. The number and position of the elastic element 8 correspond one-to-one with the number and position of the plug 7. The elastic element 8 is fixed on the side of the corresponding plug 7 away from the connecting block 5, and the elastic element 8 abuts against the corresponding plug 7, so that the plug 7 tends to move closer to the corresponding connecting block 5. A slot 34 is provided on the outer peripheral wall of each collar 3. The slot 34 is for the corresponding plug 7 to be inserted. When the plug 7 is inserted into the corresponding slot 34, the threaded sleeve 62 on the locking block 6 abuts against the inner wall of the bottom of the relief groove 33. In this embodiment, the elastic element 8 is a spring.

[0052] See Figure 8 and Figure 9The insert 7 has a slot 71 on the outer wall near the corresponding connecting block 5. The slot 71 is for the threaded sleeve 62 to be inserted. When the threaded sleeve 62 is inserted into the slot 71, the connecting block 5, the slot 6 and the insert 7 are spliced ​​to form a limiting groove 9. When the cover plate 1 is stacked vertically, the limiting groove 9 is for the threaded sleeve 62 on the adjacent cover plate 1 to be inserted. When the threaded sleeve 62 is inserted into the limiting groove 9, the arc strip 614 is used to press against the end of the threaded sleeve 62 away from the limiting groove 9.

[0053] In practical use, when transporting cover plate 1, rotate connecting block 5 so that threaded sleeve 62 faces slot 71, then loosen insert block 7 so that threaded sleeve 62 is inserted into slot 71 to form limiting groove 9. Then stack each cover plate 1 vertically together, twist the threaded sleeve 62 on the upper cover plate 1 so that threaded sleeve 62 is inserted into slot 71. The threaded sleeve 62 abuts against the inner wall of slot 71, thereby achieving limiting between each cover plate 1 in the same stack of cover plates 1, so as to reduce the situation where cover plate 1 slips and is damaged during transportation.

[0054] Meanwhile, under the action of the elastic element 613, the hinge 612 drives the arc-shaped strip 614 to extend out of the fixing part 611. The arc-shaped strip 614 abuts against the threaded sleeve 62, so that the threaded sleeve 62 and the threads on the fixing part 611 are tightly abutted, so as to reduce the loosening of the threaded sleeve 62 under the shaking caused by the movement of the transport vehicle. In addition, the hinge 612 can abut against the adjacent cover plate 1 to buffer the cover plate 1, so as to reduce the collision of the adjacent cover plate 1 under shaking.

[0055] See Figure 3 Each groove 212 has a sliding groove 213 on its inner sidewall. The sliding groove 213 is located above the collar 3. A baffle 10 is slidably connected to the cover plate 1. The number and position of the baffle 10 correspond one-to-one with the number and position of the groove 212. The baffle 10 slides closer to or away from the corresponding groove 212, and the sliding direction of the baffle 10 is parallel to the rotation axis of the connecting block 5. The sliding groove 213 is for the baffle 10 to be inserted.

[0056] See Figure 3 and Figure 4 Each groove 212 has a relief cavity 214 on its inner sidewall. The relief cavity 214 is located below the slide groove 213 and communicates with the slide groove 213. Each relief cavity 214 penetrates the groove 2 in the direction close to the cover plate 1. A support rod group is fixed on the groove 2. The number and position of the support rod group correspond one-to-one with the number and position of the groove 212. Each support rod group is located in the corresponding relief cavity 214. Each support rod group includes two support rods 12. The two support rods 12 are located at the end of the relief cavity 214 close to the cover plate 1 and are located on opposite sides of the groove 212. The support rods 12 are used to abut against the baffle 10 in the slide groove 213.

[0057] See Figure 3Each groove 212 has a limiting plate 13 fixed on its two opposite inner sidewalls. The two limiting plates 13 are located above the groove 213. The two limiting plates 13 are aligned and spaced apart. The upper end face of the limiting plate 13 is flush with the upper end face of the groove 2. The limiting plate 13 is used to abut against the baffle 10.

[0058] See Figure 2 and Figure 3 The cover plate 1 has several supports 14 that slide up and down. The supports 14 are distributed along the length of the cover plate 1, and the number and position of the supports 14 correspond one-to-one with the number and position of the grooves 212 on the same side of the cover plate 1. Each support 14 includes a base 141 and two sliding rods 142. The base 141 is located below the cover plate 1, and several protrusions 15 are fixed on the base 141. The protrusions 15 are spaced apart from each other, and the position of the protrusions 15 corresponds to the position of the filter holes 11. The protrusions 15 are used to pass through the corresponding filter holes 11.

[0059] See Figure 3 and Figure 10 Two sliding rods 142 are located on opposite sides of the base 141 and fixed above the base 141. Both sliding rods 142 are extended upward through the cover plate 1. A movable ball 16 is fixed at the upper end of each sliding rod 142. A slide rail 101 is provided on the lower end face of the baffle 10. The number and position of the slide rails 101 correspond one-to-one with the number and position of the movable balls 16. The length direction of each slide rail 101 is set along the sliding direction of the baffle 10. The movable ball 16 is located in the corresponding slide rail 101.

[0060] See Figure 2 and Figure 3 The base 141, two sliding rods 142, and cover plate 1 are joined together to form a water passage 17. The water passage 17 is located below the cover plate 1 and communicates with the filter hole 11. Several elastic elements 18 are fixed on the base 141. The elastic elements 18 are located between the base 141 and the cover plate 1. The number and position of the elastic elements 18 correspond one-to-one with the number and position of the sliding rods 142. Each elastic element 18 is sleeved on the outside of the corresponding sliding rod 142, and the opposite ends of each elastic element 18 are fixedly connected to the base 141 and the cover plate 1, respectively. The elastic elements 18 press against the base 141 and the cover plate 1, so that the base 141 has a downward tendency. In this embodiment, the elastic element 18 is a spring.

[0061] In practical use, when the baffle 10 is disengaged from the slide groove 213, the baffle 10 is limited by the limiting plate 13, so as to reduce the situation where the baffle 10 is tilted under the action of the elastic element 18. On the other hand, when pedestrians pass through the drainage ditch, the limiting plate 13 provides support to reduce the damage to the baffle 10 after being stepped on by pedestrians multiple times, which helps to extend the service life of the baffle 10.

[0062] The implementation principle of a drainage ditch in this application embodiment is as follows:

[0063] When it is necessary to install cover plate 1, place cover plate 1 in receiving groove 211, and then move collar 3 close to cover plate 1 until connecting block 5 and locking block 6 are both engaged in notch 32 and locking block 6 is located in relief groove 33. Rotate collar 3 so that locking block 6 and notch 32 are misaligned and insert block 7 and slot 34 are aligned. At this time, insert block 7 slides close to connecting block 5 and engages in slot 34 under the action of elastic element 8. Insert block 7 abuts against the inner wall of slot 34 and threaded sleeve 62 abuts against the inner wall of relief groove 33, suppressing the slippage and rotation of collar 3, realizing the positioning of collar 3. And through collar 3 abutting against groove 2 and connecting block 5, the cover plate 1 is installed on groove 2. No screwdriver or other installation tools are needed, reducing the trouble caused by forgetting installation tools. Compared with threaded connection, the operation time is shorter, which helps to improve the installation efficiency of drainage ditch.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
