Abstract
Description
A drainage ditch Technical Field
[0001] This utility model relates to a drainage system, and more specifically, to a drainage ditch. Background Technology
[0002] Drainage ditches are a crucial part of the drainage system. They are typically installed along roadsides or at the entrances of underground buildings to prevent excessive water accumulation and flooding, thus effectively protecting people's property.
[0003] The drainage ditch includes a ditch body and a ditch cover installed on the ditch body. A U-shaped groove is formed in the ditch body, and several openings are formed on the ditch cover for water to leak into the groove. In order to maintain the stability of the connection between the ditch cover and the ditch body, in the prior art, the ditch cover is usually designed to be relatively heavy, so that the ditch cover is not easy to detach from the ditch body when pedestrians or vehicles pass over it.
[0004] However, debris mixed in with the stagnant water will enter the ditch through the drain outlet along with the water flow, affecting the drainage efficiency of the ditch. People need to clean the debris in the drainage ditch regularly, but because the ditch cover is heavy, people usually need to use tools to open the ditch cover, which is time-consuming and laborious.
[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drainage ditch.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a drainage ditch, including a ditch body and a ditch cover, wherein two grooves are provided on the ditch body for placing the two ends of the ditch cover respectively, and slots are provided on the opposite side walls of the two grooves; the two ends of the ditch cover are provided with a locking block that can extend and be embedded in the locking slot; the top surface of the ditch cover is provided with a control component for controlling the extension and retraction of the locking block; and a weight-reducing cavity is provided in the ditch cover.
[0008] The present invention is further configured such that: the top surface of the trench cover has a circular hole communicating with the weight reduction cavity; the control component includes a handle rotatably connected in the circular hole and a gear slidably connected in the weight reduction cavity; one end of the handle is fixed with a gear meshing with the gear; and the locking block is fixed to one end of the gear.
[0009] The present invention is further configured such that: the end of the handle away from the gear is rotatably connected to a buckle that can be stored in a round hole.
[0010] The present invention is further configured such that the area of the card block away from the end face of the toothed bar is smaller than the opening area of the card slot.
[0011] The present invention is further provided that: a rubber strip for contacting the groove cover is attached to the side wall of the groove.
[0012] The present invention is further configured such that: the number of the card blocks is four, and the four card blocks are respectively located near the four corners of the trench cover.
[0013] The present invention is further configured such that the trench cover is made of resin concrete.
[0014] In summary, this utility model has the following beneficial effects: When a large amount of debris accumulates in the trench and needs to be cleaned, the locking block can be pulled out of the slot by the control component. At this time, the locking block no longer abuts against the inner wall of the slot, so that the locking block no longer restricts the trench cover. People can then remove the trench cover from the trench body and begin the trench cleaning work. The weight-reducing cavity can effectively reduce the weight of the trench cover, making it easier to remove the trench cover from the trench body. When the locking block is embedded in the slot, it abuts against the inner wall of the slot. When vehicles or pedestrians pass over the trench cover, the locking block can effectively restrict the trench cover, making it difficult for the trench cover to fall off the trench body. The control component allows people to extend and retract the locking block by operating the control component, thus facilitating the disassembly or installation of the trench cover.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] A drainage ditch, as shown in Figures 1 and 2, includes a ditch body 1 and a ditch cover 2. The ditch body 1 has a channel for accommodating accumulated water. Two grooves 3 are formed on the ditch body 1 for placing the ends of the ditch cover 2. Slots 4 are formed on the opposite side walls of the two grooves 3. The ends of the ditch cover 2 are provided with locking blocks 5 that can extend and embed into the slots 4. The top surface of the ditch cover 2 is provided with a control element for controlling the extension and retraction of the locking blocks 5. A weight-reducing cavity 6 is provided in the ditch cover 2. When a large amount of debris accumulates in the ditch and needs to be cleaned, the locking blocks 5 are pulled out of the slots 4 by the control element. At this time, the locking blocks 5 no longer abut against the inner wall of the slots 4, so that the locking blocks 5 no longer obstruct the drainage. The cover 2 acts as a limit, allowing people to remove the trench cover 2 from the trench body 1, and then begin the trench cleaning work. The weight-reducing cavity 6 effectively reduces the weight of the trench cover 2, making it easier to remove the trench cover 2 from the trench body 1. When the locking block 5 is embedded in the locking groove 4, the locking block 5 abuts against the inner wall of the locking groove 4. When vehicles or pedestrians pass over the trench cover 2, the locking block 5 effectively limits the trench cover 2, making it difficult for the trench cover 2 to fall off the trench body 1. The control component allows people to extend and retract the locking block 5 by operating the control component, thus facilitating the removal or installation of the trench cover 2.
[0020] As shown in Figure 2, the top surface of the trench cover 2 has a circular hole 7 communicating with the weight-reducing cavity 6. The control components include a handle 8 rotatably connected in the circular hole 7 and a gear 9 slidably connected in the weight-reducing cavity 6. One end of the handle 8 is fixed with a gear 10 that meshes with the gear 9. A locking block 5 is fixed to one end of the gear 9. When disassembling the trench cover 2, people rotate the handle 8, which drives the gear 10 to rotate. The gear 10 converts the torque applied to the handle 8 into a force that pushes the gear 9 backward through the gear 9, causing the locking block 5 to retract into the weight-reducing cavity 6 along with the end of the gear 9. The handle 8 allows people to extend and retract the gear 9 by operating the handle 8. The end of the handle 8 away from the gear 10 is rotatably connected with a retaining ring 11 that can be stored in the circular hole 7. Neither the retaining ring 11 nor the handle 8 protrudes from the upper surface of the trench cover 2. When it is necessary to rotate the handle 8, people can use their hands to remove the retaining ring 11 from the gear 9. The handle 8 is rotated by applying force to the buckle 11 after the buckle is fastened into the round hole 7. The buckle 11 provides a good point of force for rotating the handle 8. It can also be rotated back into the round hole 7 after use, so that the buckle 11 does not protrude from the upper surface of the trench cover 2, making the upper surface of the trench cover 2 relatively flat. At the same time, the round hole 7 can also protect the buckle 11 when vehicles or pedestrians pass over the trench cover 2, thus extending the service life of the buckle 11. The area of the end face of the locking block 5 away from the toothed rod 9 is smaller than the opening area of the slot 4. The four edges of the end face of the locking block 5 away from the toothed rod 9 are all chamfered. This setting ensures that the area of the locking block 5 facing the inner wall of the slot 4 is better when the locking block 5 is inserted into the slot 4, so that the locking block 5 can be inserted into the slot 4 more quickly.
[0021] As shown in Figures 1 and 2, rubber strips 12 are attached to the sidewalls of the groove 3 to abut against the trench cover 2. When pedestrians or vehicles pass over the trench cover 2, the rubber strips 12 can effectively absorb the vibration between the trench cover 2 and the trench body 1, thus providing better buffering for the collision between the trench cover 2 and the trench body 1, and also reducing noise. There are four locking blocks 5, which are respectively set near the four corners of the trench cover 2. One of the handles 8 can control two locking blocks 5 at the same time. When the locking blocks 5 are embedded in the slots 4 and limit the trench cover 2, the locking blocks 5 set near the four corners of the trench cover 2 can make the trench cover 2 and the trench body 1 more securely fixed, so that when pedestrians or vehicles pass over the trench cover 2, the vibration between the trench cover 2 and the trench body 1 is effectively absorbed. When passing over the trench cover 2, the trench cover 2 is not prone to excessive shaking. The weight-reducing cavity 6 has reinforcing ribs formed on both sides of the handle 8 and does not contact the toothed rod 9. The reinforcing ribs can effectively improve the strength of the inner wall of the weight-reducing cavity 6. When pedestrians or vehicles pass over the trench cover 2, the upper surface of the trench cover 2 is not prone to denting due to the setting of the weight-reducing cavity 6, thus better protecting the toothed rod 9 in the weight-reducing cavity 6. The trench cover 2 is made of resin concrete. Compared with ordinary concrete, resin concrete has the advantages of high strength and low density. The trench cover 2 made of resin concrete can ensure that the trench cover 2 has sufficient strength while being lightweight, thus making it easier for people to disassemble the trench cover 2.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
