Description

Technical Field

[0001] This utility model relates to the field of bridge drainage technology, specifically a drainage device for road and bridge engineering. Background Technology

[0002] Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, bridges have also been extended to refer to structures built across mountains, streams, or adverse geological conditions to meet other transportation needs and make travel more convenient. Bridge engineering refers to the work process of surveying, designing, constructing, maintaining, and inspecting bridges. During the construction of bridges, drainage devices are usually installed to drain water from the bridge.

[0003] Publication number CN218291585U discloses a drainage device for road and bridge engineering. By setting a float, when dirt in the filter tank clogs the filter screen, the water level rises. At this time, the float drives the debris-blocking frame to pull the dirt covering the filter screen upwards. Simultaneously, the baffle disengages from the opening of the filter tank, and the dirt flows with the water into the drainage trough for collection. The filter cylinder can collect the dirt flowing into the drainage trough for subsequent centralized treatment. Opening the top cover simultaneously pulls the dirt out of the filter cylinder using the connecting plate. The fixing plate guides the water flow to the side of the inlet tank to prevent it from impacting the float and preventing it from floating. However, this patent still has the following problems in actual use: By setting a float, when the dirt in the filter tank clogs the filter screen, the water level will rise. At this time, the float will drive the debris baffle to pull the dirt covering the filter screen upwards. At the same time, the baffle will disengage from the opening of the filter tank, and the dirt will flow into the drain tank for collection with the water flow. The filter cylinder can collect the dirt flowing into the drain tank for subsequent centralized treatment. Opening the top cover will drive the connecting plate to pull the dirt in the filter cylinder upwards. The fixing plate can guide the water flow to the side of the inlet tank to prevent it from impacting the float and preventing it from floating. However, when it is necessary to clean the float and debris on the debris baffle, it is not easy to pull up the float and debris baffle, making it inconvenient to clean the debris on the debris baffle.

[0004] A drainage device for road and bridge engineering is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage device for road and bridge engineering, to solve the problem mentioned in the background art that currently, when a float is set up, the water level rises when the filter screen is clogged by dirt in the filter tank. At this time, the float drives the debris-blocking frame to pull the dirt covering the filter screen upwards, and at the same time, the baffle disengages from the opening of the filter tank, and the dirt flows into the sewage trough for collection. The filter cylinder can collect the dirt flowing into the sewage trough for subsequent centralized treatment. When the top cover is opened, the connecting plate pulls the dirt in the filter cylinder upwards. The fixing plate can guide the water flow to the side of the water inlet tank to prevent it from impacting the float and preventing it from floating. However, when it is necessary to clean the float and debris on the debris-blocking frame, it is not easy to pull up the float and debris-blocking frame, which makes it inconvenient to clean the debris on the debris-blocking frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage device for road and bridge engineering, comprising a main drainage pipe, wherein auxiliary drainage pipes are connected through the two sides of the main drainage pipe near the bottom. A first filter element is fixedly installed on the top surface of the main drain pipe, a second filter element is fixedly installed in the middle of the bottom surface of the first filter element, a baffle is fixedly installed inside the main drain pipe, and symmetrical grooves are opened inside the main drain pipe. Also includes: A filter assembly is provided on the top surface of the baffle; The filter assembly includes a sealing slider that is slidably connected to the chute; A filter screen is fixedly connected to the side of the sealing slider away from the slide groove.

[0007] Preferably, a fixing rod is fixedly connected to the middle of the top surface of the filter screen, a first float is connected through the surface of the fixing rod, and a second float is arranged above the first float, the second float being connected through the fixing rod.

[0008] Preferably, a lifting ring is fixedly installed on the top surface of the fixing rod.

[0009] Preferably, a sealing rubber corrugated plate is fixedly connected to the top surface of the sealing slider, and the top surface of the sealing rubber corrugated plate is fixedly connected to the groove.

[0010] Preferably, the first and second filter elements are made of 304 stainless steel.

[0011] Preferably, the first and second floats are made of closed-cell foam plastic.

[0012] Preferably, the fixing rod is made of 304 galvanized steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This drainage device for road and bridge engineering, by setting up a filter component, can not only intercept garbage, but also make it easier for workers to clean the garbage on the filter component, thereby improving the work efficiency of the workers. The specific details are as follows: 1. By setting up a filtration assembly, larger debris can be intercepted when sewage passes through the first and second filter elements. Some debris in the sewage will then enter the main drain pipe with the water flow. The filter screen on the filtration assembly will then intercept the debris in the sewage again. If the filter screen becomes clogged and the sewage cannot be discharged, the first and second floats will rise under the buoyancy of the sewage, thereby driving the filter screen and sealing slider to rise. This allows the sewage to flow out through the gap between the filter screen and the main drain pipe, thus preventing sewage accumulation to a certain extent. At the same time, when cleaning the debris on the filter screen, the first filter element is separated from the main drain pipe, and then a tool is used to hook the lifting ring, which can drive the entire filtration assembly to rise. This makes it easier for workers to clean the debris on the filter screen, thereby improving the work efficiency of the workers. 2. By setting up a first filter element, a second filter element, and a sealing rubber corrugated plate, the first and second filter elements can intercept most of the garbage in the sewage. At the same time, the sealing rubber corrugated plate can prevent garbage in the sewage from entering the interior of the chute. The sealing rubber corrugated plate is made of EPDM rubber, which gives it excellent weather resistance: it is resistant to ultraviolet rays and high and low temperatures. It is not easy to age and crack when exposed to the outdoors for a long time, and its lifespan can reach 15-20 years. It has excellent water resistance and weak corrosion resistance, strong resistance to weak acids and weak alkalis in rainwater and municipal sewage, does not swell or degrade, and has good elastic recovery. The corrugated structure can adapt to the slight deformation of the drainage pipe caused by temperature changes or foundation settlement, and maintain a continuous seal to prevent water leakage. At the same time, the traditional symmetrical corrugation is changed to an inverted cone shape that is wider at the top and narrower at the bottom. The depth of the trough gradually decreases from the inlet to the inside, reducing the retention of garbage in the trough. At the same time, the gravity of the water flow is used to flush the garbage to the main channel of the pipeline. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a drainage device for road and bridge engineering, including a main drainage pipe 1, with auxiliary drainage pipes 2 connected through both sides of the main drainage pipe 1 near the bottom; a first filter element 3 is fixedly installed on the top surface of the main drainage pipe 1, a second filter element 4 is fixedly installed in the middle of the bottom surface of the first filter element 3, a baffle 5 is fixedly installed inside the main drainage pipe 1, and symmetrical grooves 6 are formed inside the main drainage pipe 1; it also includes: a filter assembly 8 provided on the top surface of the baffle 5; wherein the filter assembly 8 includes a sealing slider 801 slidably connected to the groove 6; wherein a filter screen 802 is fixedly connected to the side surface of the sealing slider 801 away from the groove 6, such as Figure 1-5 As shown, by setting up the filter component 8, it can not only intercept garbage, but also make it easier for staff to clean the garbage on the filter component 8, thereby improving the work efficiency of the staff. At the same time, the secondary drain pipe 2 can assist the main drain pipe 1 in discharging sewage.

[0018] A fixing rod 803 is fixedly connected to the middle of the top surface of the filter screen 802. A first float 804 is connected through the surface of the fixing rod 803. A second float 805 is located above the first float 804 and is connected through the fixing rod 803. A hanging ring 806 is fixedly installed on the top surface of the fixing rod 803. Figure 5As shown, when sewage passes through the first filter element 3 and the second filter element 4, larger debris can be intercepted. Some of the debris in the sewage will then enter the main drain pipe 1 with the water flow. At this point, the filter screen 802 on the filter assembly 8 will intercept the debris again. If the filter screen 802 becomes clogged and sewage cannot drain, the first float 804 and the second float 805 will rise due to the buoyancy of the sewage. This will cause the filter screen 802 and the sealing slider 801 to rise, allowing the sewage to flow out through the gap between the filter screen 802 and the main drain pipe 1. This can, to a certain extent, prevent the sewage from overflowing. The accumulation of water, while cleaning the debris on the filter screen 802, involves separating the first filter element 3 from the main drain pipe 1, and then using a tool to hook the lifting ring 806, which allows the entire filter assembly 8 to be lifted, making it easier for workers to clean the debris on the filter screen 802 and improving their work efficiency. The filter screen 802 is made of stainless steel mesh with a pore size of 0.1–1 mm, high strength, and can withstand high temperatures, making it suitable for high-frequency rinsing. Meanwhile, the sealing slider 801 is made of POM, resulting in an extremely low coefficient of friction, wear resistance, suitability for frequent sliding scenarios, and resistance to sewage corrosion.

[0019] A sealing rubber corrugated plate 7 is fixedly connected to the top surface of the sealing slider 801. The top surface of the sealing rubber corrugated plate 7 is fixedly connected to the slide groove 6, such as... Figure 3 As shown, by setting up a first filter element 3, a second filter element 4, and a sealing rubber corrugated plate 7, the first filter element 3 and the second filter element 4 can intercept most of the garbage in the sewage. At the same time, the sealing rubber corrugated plate 7 can prevent garbage in the sewage from entering the interior of the chute 6. The sealing rubber corrugated plate 7 is made of EPDM rubber, which gives it extremely strong weather resistance: UV resistance, high and low temperature resistance, and it is not easy to age and crack when exposed to the outdoors for a long time. Its lifespan can reach 15 to 20 years. It has excellent water resistance and weak corrosion resistance, strong resistance to weak acids and weak alkalis in rainwater and municipal sewage, does not swell or degrade, and has good elastic recovery. The corrugated structure can adapt to the slight deformation of the drainage pipe caused by temperature changes or foundation settlement, and maintain a continuous seal to prevent water leakage. At the same time, the traditional symmetrical corrugation is changed to an inverted cone shape that is "wider at the top and narrower at the bottom". The depth of the trough gradually becomes shallower from the inlet to the inside, reducing the retention of garbage in the trough. At the same time, the gravity of the water flow is used to flush the garbage to the main channel of the pipeline.

[0020] The first filter element 3 and the second filter element 4 are made of 304 stainless steel, such as Figure 2 As shown, this results in excellent corrosion and rust resistance, while also being low in cost, lightweight, and easy to process and shape.

[0021] The first float 804 and the second float 805 are made of closed-cell foam plastic, such as Figure 5As shown, this gives it extremely low density, strong buoyancy, water resistance and non-absorption, and good flexibility, thus enabling it to float better.

[0022] The fixing rod 803 is made of 304 galvanized steel, such as Figure 5 As shown, the fixing rod 803 is made of 304 galvanized steel, which gives it good corrosion and rust resistance.

[0023] Working principle: Before using this type of drainage device for road and bridge engineering, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, by first setting up the filter assembly 8, when sewage passes through the first filter element 3 and the second filter element 4, larger debris can be intercepted. At this time, some debris in the sewage will enter the main drain pipe 1 with the water flow. Then, the filter screen 802 on the filter assembly 8 will intercept the debris in the sewage again. If the filter screen 802 becomes clogged and the sewage cannot be discharged, the first float 804 and the second float 805 will rise under the buoyancy of the sewage, thereby driving the filter screen 802 and the sealing slider 801 to rise, so that the sewage will flow out through the gap between the filter screen 802 and the main drain pipe 1, thus avoiding the accumulation of sewage to a certain extent. At the same time, when cleaning the debris on the filter screen 802, the first filter element 3 is separated from the main drain pipe 1, and then the lifting ring 806 is hooked with a tool, so that the entire filter assembly 8 can be lifted, making it easier for the staff to clean the debris on the filter screen 802, thereby improving the work efficiency of the staff.

[0024] Secondly, by setting up the first filter element 3, the second filter element 4, and the sealing rubber corrugated plate 7, the first filter element 3 and the second filter element 4 can intercept most of the garbage in the sewage. At the same time, the sealing rubber corrugated plate 7 can prevent garbage in the sewage from entering the interior of the chute 6. The sealing rubber corrugated plate 7 is made of EPDM rubber, which gives it excellent weather resistance: UV resistance, high and low temperature resistance, and it is not easy to age and crack when exposed to the outdoors for a long time. Its lifespan can reach 15 to 20 years. It has excellent water resistance and weak corrosion resistance, strong resistance to weak acids and weak alkalis in rainwater and municipal sewage, does not swell or degrade, and has good elastic recovery. The corrugated structure can adapt to the slight deformation of the drainage pipe caused by temperature changes or foundation settlement, and maintain a continuous seal to prevent water leakage. At the same time, the traditional symmetrical corrugation is changed to an inverted cone shape that is "wider at the top and narrower at the bottom". The depth of the trough gradually becomes shallower from the inlet to the inside, reducing the retention of garbage in the trough. At the same time, the gravity of the water flow is used to flush the garbage to the main channel of the pipeline.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
