Description

Technical Field

[0001] The present application relates to the technical field of municipal engineering drainage, and specifically to a drainage device for municipal engineering. Background Art

[0002] Municipal engineering refers to municipal infrastructure construction projects, including the construction of some urban roads. When constructing urban roads, it is necessary to consider the drainage of roads on rainy days. Nowadays, municipal road drainage is mainly achieved through manholes set up on the roads and drainage outlets on both sides of the roads. The rainwater on the road surface is drained into the sewers through manholes and drainage outlets, and further drained to rivers and other places for drainage.

[0003] A Chinese patent (publication number: CN214460947U) discloses a drainage device for municipal engineering, including a filter tank, a drainage pipe is provided on the upper part of the filter tank, a cover seat is provided on the upper end of the drainage pipe, a water storage tank is provided on the side of the filter tank, and a water pipe is connected between the water storage tank and the filter tank; fixed plates are provided on the upper and lower sides of the side of the filter tank, and a positioning rod is provided on the side of the filter tank and close to the two fixed plates; a clamping plate is provided in the fixed plate, screws are provided on the fixed plate, the clamping plate is connected to the fixed plate by the screws, a straight rod is connected between the upper and lower clamping plates, the positioning rod passes through the straight rod and a nut is provided at the end. The drainage device disclosed in the search patent can enhance the firmness of the connection between the filter tank and the pipeline, and ensure the stability of sewage when flowing through.

[0004] However, the above drainage device still has some shortcomings. When producing the device, since the device structure cannot be formed in one piece, it is necessary to process individual components first and then assemble them. During assembly, some components that need to be fixed are generally fixed by welding, such as between the water pipe and the filter tank, between the fixing plate and the filter tank, and between the reinforcing rib and the filter tank. If the manufacturer welds each part before leaving the factory, the water pipe between the filter tank and the water reservoir is very likely to bend or even be damaged and ruptured due to torsion during transportation. If it is not welded before leaving the factory, it needs to be welded at the municipal road construction site, which greatly reduces the work efficiency of the on-site construction of municipal engineering. Therefore, a drainage device for municipal engineering is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a drainage device for municipal engineering, which has the advantages of convenient transportation and assembly, and solves the problem of low practicality of the above-mentioned search patent.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a drainage device for municipal engineering, comprising a filter tank, a connecting pipe and a water storage tank, wherein a water inlet pipe is fixed to the top surface of the filter tank, a mounting mechanism is provided on the connecting pipe, and both ends of the connecting pipe are connected to the filter tank and the water storage tank through the mounting mechanism, and a sealing assembly is provided on the connecting pipe;

[0007] The mounting mechanism comprises two fixed bins respectively fixed on the front side of the filter tank and the front side of the water storage tank, a notch is provided on the front side of the fixed bins, mounting rings are fixed on both ends of the connecting pipe, a rotating rod is rotatably connected between the upper and lower inner walls of the fixed bins, two thread grooves with opposite thread directions are provided on the outer peripheral wall of the rotating rod, a sliding groove is provided on the opposite sides of the inner cavity of the two fixed bins, two sliders are slidably connected in the sliding groove, an extrusion strip is fixed on the side of the slider facing the rotating rod, and the extrusion strip is threadedly connected to the rotating rod through a thread groove.

[0008] By adopting the above technical solution, the device can be divided into three parts, namely the filter tank, the connecting pipe and the water reservoir, for processing and transportation, thereby avoiding relative displacement between the filter tank and the water reservoir during transportation, which may cause the connecting pipe to be damaged by torsional bending, reducing losses during transportation, being more practical, and facilitating rapid assembly at the municipal construction site.

[0009] Furthermore, the top view of the connecting pipe is U-shaped, and the water inlet pipe is connected to the filter tank.

[0010] The above technical solution makes it convenient to introduce rainwater from the road surface into the filter tank through the water inlet pipe.

[0011] Furthermore, one side and the back side opposite to each other of the two fixed bins are both missing, and two triangular reinforcing ribs are fixed on the top and bottom surfaces of the fixed bins.

[0012] By adopting the above technical solution, the stability of the connection between the fixed bin and the filter tank can be increased by setting the triangular reinforcement ribs, thereby improving the stability of the installation mechanism for the connecting pipe.

[0013] Furthermore, the notch is communicated with a side of the fixed bin close to the connecting pipe, and the height of the notch is greater than the diameter of the connecting pipe.

[0014] The above technical solution makes it easy to insert the connecting pipe into the slot, thereby facilitating the installation of the connecting pipe.

[0015] Furthermore, the top end of the rotating rod vertically penetrates the fixed bin and extends to the top of the fixed bin, a handle is fixed to the top end of the rotating rod, and the two thread grooves on the same rotating rod are distributed up and down.

[0016] By adopting the above technical solution, the connecting pipe can be installed by conveniently rotating the rotating rod through the provided handle.

[0017] Furthermore, a threaded hole for the rotating rod to vertically penetrate and adapted to the threaded groove is provided on the top surface of the extruded strip, and a side of the extruded strip facing the mounting ring is an inclined surface.

[0018] By adopting the above technical solution, the inclined surface is arranged so that the upper and lower extrusion strips can generate a backward extrusion force on the installation ring when they move relative to each other, so as to improve the stability of the installation.

[0019] Furthermore, the sealing assembly includes an annular plate fixed on the back of the mounting ring, an annular groove is provided on the front of the filter pool and the front of the water reservoir, an annular rubber pad is fixed on the inner wall of the back of the annular groove, and a circular hole is provided on the front of the filter pool and the front of the water reservoir.

[0020] The adoption of the above technical solution can ensure the sealing of both ends of the connecting pipe and avoid water leakage and the like.

[0021] Furthermore, the annular plate and the annular groove are clearance-matched, and the circular hole and the annular groove are located on the same central axis.

[0022] The above technical solution is adopted to facilitate the flow of rainwater between the circular hole and the connecting pipe.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1. The drainage device for municipal engineering is divided into three parts for processing during production: filter tank, connecting pipe and water reservoir. After processing, it is directly packaged and transported to the municipal road construction site.

The operation is simple and convenient, which avoids wasting municipal construction time and is more efficient. In addition, the sealing assembly can ensure the sealing of both ends of the connecting pipe to avoid water leakage, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] See also Figure 1-3 The municipal engineering drainage device in this embodiment includes a filter tank 1, a connecting pipe 2 and a water reservoir 3. A water inlet pipe 4 is fixed to the top surface of the filter tank 1. When the device is produced, the device is divided into three parts, namely the filter tank 1, the connecting pipe 2 and the water reservoir 3 for processing. After processing, the device is directly packaged and transported to the municipal road construction site. The filter tank 1, the connecting pipe 2 and the water reservoir 3 are transported in three parts to avoid relative displacement between the filter tank 1 and the water reservoir 3 during transportation, which may cause torsional bending damage to the connecting pipe 2, reduce losses during transportation, and be more practical.

[0032] In addition, a mounting mechanism 5 is provided on the connecting pipe 2, and the two ends of the connecting pipe 2 are connected to the filter tank 1 and the water reservoir 3 through the mounting mechanism 5. After the three main parts of the filter tank 1, the connecting pipe 2 and the water reservoir 3 are transported to the municipal road construction site, the connecting pipe 2 can be quickly connected to the filter tank 1 and the water reservoir 3 through the mounting mechanism 5. The operation is simple and convenient, avoids wasting municipal construction time, and is more efficient. A sealing component 6 is provided on the connecting pipe 2, and the sealing component 6 can ensure the sealing of the two ends of the connecting pipe 2 to avoid water leakage and the like, which is more practical.

[0033] The mounting mechanism 5 comprises two fixed bins 501 respectively fixed on the front of the filter tank 1 and the front of the water storage tank 3, a notch 502 is provided on the front of the fixed bin 501, mounting rings 503 are fixed on both ends of the connecting pipe 2, a rotating rod 504 is rotatably connected between the upper and lower inner walls of the fixed bin 501, and during assembly, the end of the connecting pipe 2 is inserted into the fixed bin 501, and the rotating rod 504 is rotated. Two thread grooves 505 with opposite thread directions are provided on the outer peripheral wall of the rotating rod 504, and sliding grooves are provided on the opposite sides of the inner cavities of the two fixed bins 501. 506, two sliders 507 are slidably connected in the slide groove 506, and an extrusion strip 508 is fixed on the side of the slider 507 facing the rotating rod 504. The extrusion strip 508 is threadedly connected to the rotating rod 504 through a threaded groove 505. The rotating rod 504 drives the two extrusion strips 508 to slide relatively along the slide groove 506 through the two threaded grooves 505. Further, the extrusion strip 508 moves to abut against the front side of the mounting ring 503, thereby limiting the forward and backward movement of the mounting ring 503, so that it abuts and is fixed to the filter tank 1 or the water storage tank 3, thereby completing the installation of the connecting pipe 2.

[0034] The top view of the connecting pipe 2 is U-shaped, and the water inlet pipe 4 is connected to the filter tank 1, which is convenient for introducing rainwater from the road into the filter tank 1 through the water inlet pipe 4. The opposite side and the back of the two fixed bins 501 are missing, and two triangular reinforcing ribs are fixed on the top and bottom surfaces of the fixed bin 501. The triangular reinforcing ribs can increase the stability of the connection between the fixed bin 501 and the filter tank 1, thereby improving the stability of the installation of the connecting pipe 2 by the installation mechanism 5. The missing groove 502 is connected to the side of the fixed bin 501 close to the connecting pipe 2, and the height of the missing groove 502 is greater than the diameter of the connecting pipe 2. The top of the rotating rod 504 vertically penetrates the fixed bin 501 and extends to its top. A handle is fixed to the top of the rotating rod 504. Two threaded grooves 505 on the same rotating rod 504 are distributed up and down. A threaded hole for the rotating rod 504 to vertically penetrate and match the threaded groove 505 is provided on the top surface of the extrusion strip 508, and the side of the extrusion strip 508 facing the mounting ring 503 is an inclined surface.

[0035] See also Figure 3 In this embodiment, the sealing assembly 6 includes an annular plate 601 fixed on the back of the mounting ring 503, an annular groove 602 is provided on the front of the filter pool 1 and the front of the water reservoir 3, and an annular rubber pad 603 is fixed on the inner wall of the back of the annular groove 602. When the connecting pipe 2 is inserted into the fixing bin 501, the annular plate 601 on the back of the mounting ring 503 is opposite to the annular groove 602, and the annular plate 601 is inserted into the annular groove 602, so that the annular plate 601 squeezes the annular rubber pad 603 to achieve a sealing effect. Circular holes 604 are provided on the front of the filter pool 1 and the front of the water reservoir 3. At this time, water can flow through the circular hole 604 and the connecting pipe 2.

[0036] It should be understood that the annular plate 601 and the annular groove 602 not only play a sealing role, but also play a positioning and limiting role, so that the connecting pipe 2 can be easily connected to the circular hole 604, and at the same time, the movement of the installation ring 503 can be avoided.

[0037] In this embodiment, the annular plate 601 and the annular groove 602 are clearance-matched, and the inclined surface is set so that the upper and lower extrusion strips 508 can generate a backward extrusion force on the mounting ring 503 when they move relative to each other, thereby better extruding the annular rubber pad 603 for sealing, and the circular hole 604 and the annular groove 602 are located on the same central axis.

[0038] The working principle of the above embodiment is:

[0039] During assembly, insert the end of the connecting pipe 2 into the fixed bin 501, rotate the rotating rod 504, and the rotating rod 504 drives the two extrusion strips 508 to slide relative to each other along the slide groove 506 through the two threaded grooves 505. Further, the extrusion strip 508 moves to abut against the front side of the mounting ring 503, thereby limiting the forward and backward movement of the mounting ring 503, so that it abuts and is fixed to the filter tank 1 or the water storage tank 3, thereby completing the installation of the connecting pipe 2.

[0040] When the connecting pipe 2 is inserted into the fixing chamber 501, the annular plate 601 on the back of the mounting ring 503 is aligned with the annular groove 602, and the annular plate 601 is inserted into the annular groove 602 so that the annular plate 601 squeezes the annular rubber pad 603 to achieve a sealing effect. At this time, water can flow through the circular hole 604 and the connecting pipe 2.
