Description

Technical Field

[0001] This utility model relates to a drainage ditch, specifically a prefabricated assembled drainage ditch that is easy to install and replace, and belongs to the field of drainage ditch technology. Background Technology

[0002] Drainage ditches are key facilities for the rapid drainage of rainwater and sewage. To meet the demands of modern engineering for construction efficiency and transportation convenience, existing drainage ditches generally adopt a prefabricated assembly structure design. By breaking down the ditch into standardized prefabricated units, the intensity of on-site pouring operations is greatly reduced. At the same time, it facilitates factory production and long-distance transportation, effectively improving the efficiency of engineering construction.

[0003] However, most existing prefabricated drainage ditches have various problems. For example, in a prefabricated drainage ditch disclosed in announcement number CN217419879U, although it can extend the service life of the drainage ditch, in this technical solution and most drainage ditches currently available, in order to achieve a stable connection between adjacent prefabricated units, existing solutions mostly rely on special connectors such as screws and clips for fixing. On the one hand, this type of connection requires multiple operations on-site, such as drilling, screwing, or clip alignment, which are cumbersome and require high operational precision, directly extending the assembly time. On the other hand, drainage ditches are often laid in narrow spaces such as roadside areas and building basements, making it difficult for operators to carry out operations. This not only further increases the difficulty of installing connectors but also easily leads to incomplete connections due to limited operating space, leaving safety hazards such as leakage and structural loosening, failing to meet the dual requirements of engineering for ease of assembly and structural reliability. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a prefabricated, modular drainage ditch that is easy to install and replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A prefabricated drainage ditch that is easy to install and replace includes a ditch bottom plate, ditch side plates and an assembly mechanism. The ditch bottom plate is laid horizontally at the bottom of the drainage ditch, and the ditch side plates are vertically connected to the edge of the ditch bottom plate through the assembly mechanism and abut against the side wall of the drainage ditch.

[0007] The assembly mechanism is located between the trench bottom plate and the trench side plate, and includes a threaded rod, abutment rod, locking rod, docking cylinder, bearing tray, and clamping plate. The threaded rod is vertically fixed at the corner of the trench bottom plate. The abutment rod is coaxially connected to the top of the threaded rod. The locking rod is fixed at the top center of the abutment rod. The docking cylinder is embedded and rotatably connected to one end of the bottom of the trench side plate and slidably sleeved on the outside of the abutment rod. The bearing tray is slidably clamped to the inner axis of the docking cylinder. The clamping plate is rotatably connected to the bearing tray and is symmetrically arranged in two. The locking rod is clamped to the bottom end of two adjacent clamping plates.

[0008] As a further embodiment of this utility model, the assembly mechanism also includes a first return spring, the two ends of which are rotatably connected between two adjacent clamping plates, and the locking rod has a rectangular structure.

[0009] As a further improvement of this utility model, the assembly mechanism also includes an unlocking slot, which is recessed at the top of the docking cylinder and has an inclined structure. The top of the clamping plate is inclined and slides against the unlocking slot.

[0010] As a further improvement of this utility model: a first return spring is vertically fixed to the top of the tray, and the top end of the first return spring is fixed to the connecting cylinder.

[0011] As a further improvement of this utility model: a screw hole is provided at the bottom axis of the abutment rod, and the threaded rod is threaded into the screw hole.

[0012] As a further improvement of this utility model: an unlocking lever is coaxially fixed to the top of the tray, the unlocking lever passes through the docking cylinder and the groove side plate, and the top of the lever is located at the top of the groove side plate, and a polygonal slot is provided at the top of the unlocking lever.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, a quick connection between the trench bottom plate and the trench side plate is achieved through an assembly mechanism, eliminating the need for cumbersome steps such as drilling and screwing. During assembly, the docking sleeve of the trench side plate is simply slidably fitted onto the outside of the abutment rod. The locking rod and the clamping plate engage, and the first return spring provides elastic support to the clamping plate, thus completing the initial fixation. This significantly simplifies the operation process, shortens assembly time, and solves the problem of cumbersome operation in existing solutions. Furthermore, during the unlocking process, the locking rod and the abutment rod can be rotated on the threaded rod by the unlocking pull rod at the top, causing the abutment rod to separate from the threaded rod. This allows the entire support tray to move upwards. During this movement, the clamping plate abuts against the unlocking slot, opening the clamping plate and unlocking the abutment rod for subsequent locking operations. Moreover, operators do not need to delve into the bottom of narrow trenches, effectively adapting to narrow paving scenarios such as roadsides and basements, reducing operational difficulty, and avoiding connection problems caused by space constraints.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1 to 4 As shown, a prefabricated drainage ditch that is easy to install and replace includes a ditch bottom plate 1, a ditch side plate 2 and an assembly mechanism 3. The ditch bottom plate 1 is laid horizontally at the bottom of the drainage ditch, and the ditch side plate 2 is vertically connected to the edge of the ditch bottom plate 1 through the assembly mechanism 3 and abuts against the side wall of the drainage ditch.

[0023] Assembly mechanism 3 is set between trench bottom plate 1 and trench side plate 2, including threaded rod 31, abutment rod 32, locking rod 33, docking cylinder 34, bearing tray 35 and clamping plate 36. Threaded rod 31 is vertically fixed at the corner of trench bottom plate 1. Abutment rod 32 is coaxially connected to the top of threaded rod 31. Locking rod 33 is fixed at the top center of abutment rod 32. Docking cylinder 34 is embedded and rotatably connected to one end of bottom of trench side plate 2 and slidably sleeved on the outside of abutment rod 32. Bearing tray 35 is slidably clamped to the inner axis of docking cylinder 34. Clamping plate 36 is rotatably connected to bearing tray 35 and two are symmetrically arranged. Locking rod 33 is clamped to the bottom end of two adjacent clamping plates 36.

[0024] The assembly mechanism 3 also includes a first return spring 37, the two ends of which are rotatably connected between two adjacent clamping plates 36, and the locking rod 33 has a rectangular structure.

[0025] The assembly mechanism 3 also includes an unlocking slot 38, which is recessed at the top of the docking cylinder 34 and has an inclined structure. The top of the clamping plate 36 is inclined and slides against the unlocking slot 38.

[0026] A screw hole is provided at the bottom axis of the abutment rod 32, and the threaded rod 31 is threaded into the screw hole. The top of the support tray 35 is coaxially fixed with an unlocking pull rod 4. The unlocking pull rod 4 passes through the docking cylinder 34 and the groove side plate 2, and its top is located at the top of the groove side plate 2. A polygonal slot is provided at the top of the unlocking pull rod 4.

[0027] In this utility model, the assembly mechanism 3 enables a quick connection between the trench bottom plate 1 and the trench side plate 2, eliminating the need for tedious steps such as drilling and screwing. During assembly, the docking sleeve 34 of the trench side plate 2 is simply slidably fitted onto the outside of the abutment rod 32. The locking rod 33 engages with the clamping plate 36, and the first return spring 37 provides elastic support to the clamping plate 36, thus completing the initial fixation. This significantly simplifies the operation process, shortens assembly time, and solves the problem of cumbersome operation in existing solutions. Furthermore, the unlocking process can be achieved by using the unlocking lever 4 at the top to move the locking rod 33. The abutment rod 32 rotates on the threaded rod 31, causing the abutment rod 32 to separate from the threaded rod 31. This allows the support tray 35 to move upwards. During this movement, the support tray 35 abuts against the unlocking slot 38 via the clamping plate 36, causing the clamping plate 36 to open and unlocking the abutment rod 32 for the next locking operation. This eliminates the need for operators to work deep into narrow trenches, effectively adapting to narrow laying scenarios such as roadsides and basements, reducing operational difficulty, and avoiding connection problems caused by space constraints.

[0028] Example 2

[0029] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0030] A first return spring 37 is vertically fixed to the top of the tray 35. The top of the first return spring 37 is fixed to the docking cylinder 34. The elastic force of the first return spring 37 always presses the tray 35 downward, ensuring that the clamping plate 36 and the locking rod 33 fit tightly together, and the positioning ring 39 limits the position of the tray 35.

[0031] Working principle: When using this drainage ditch, first lay the bottom plate 1 horizontally at the bottom of the drainage ditch, then embed the bottom end of the rotatable connecting cylinder 34 into the bottom of the side plate 2 of the ditch, align it with the abutment rod 32 and slide it downward so that the connecting cylinder 34 is sleeved on the outside of the abutment rod 32 until the side plate 2 of the ditch abuts against the side wall of the drainage ditch. During the docking process, the locking rod 33 at the top of the abutment rod 32 will gradually be inserted into the bottom end of the two symmetrical clamping plates 36 on the bearing tray 35 at the center of the shaft inside the connecting cylinder 34, completing the snap-fit ​​fixing of the assembly mechanism 3 and realizing the stable connection between the bottom plate 1 of the ditch and the side plate 2 of the ditch.

[0032] When disassembling the groove side plate 2, use a tool in conjunction with the unlocking lever 4, and use the unlocking lever 4 to rotate the entire support tray 35. The clamping plate 36 drives the abutment rod 32 to rotate, causing the abutment rod 32 to separate from the threaded rod 31. At this time, pull the unlocking lever 4 upward, causing the support tray 35 to slide upward in the docking cylinder 34. During the upward movement of the support tray 35, the top of the clamping plate 36 will slide along the unlocking slot 38 recessed at the top of the docking cylinder 34, forcing the two clamping plates 36 to open to both sides, thus releasing the engagement with the locking rod 33.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
