Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary components for bridge deck drainage, specifically to a bridge deck drainage device. Background Technology
[0002] An elevated bridge is a type of bridge structure that is typically located above the ground or a road and is supported by high-supported towers or pillars. The main function of an elevated bridge is to cross deep ravines, valleys, rivers, or other road obstacles, replacing traditional ground roads or high embankments. In order to effectively drain water generated during frequent rainy days and flooding in severe weather such as typhoons and heavy rains, water collection channels and pipes are usually installed on elevated bridges.
[0003] In existing technologies, water collection channels are typically embedded in the sides of bridge decks. A filter plate is usually placed on top of the channel to prevent debris from entering and causing blockages. However, during extreme weather events such as heavy rainstorms, the filter plate can directly slow down the drainage efficiency of the channel, resulting in water accumulation on the bridge. The usual solution is for maintenance personnel to manually remove the filter plate from the top of the channel to open it and accelerate drainage. However, because the top of the channel is open and the channel has a certain depth, there is a risk of objects falling in, posing a significant safety hazard. Utility Model Content
[0004] The purpose of this utility model is to provide a bridge deck drainage device to solve the above-mentioned problems. A raised support assembly is installed at each of the four corners of the bottom surface of the filter cover plate. The pad of the raised support assembly rotates around the support axis until it is completely below the bottom surface of the filter cover plate. The filter cover plate can be supported and placed in the top opening of the water collection tank body by the bottom surface of the pad contacting the top surface of the placement flange. The support method of placing the filter cover plate in the top opening of the water collection tank body is simple and easy to implement, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The present invention provides a bridge deck drainage device, including a water collection trough body and a filter cover plate. The top of the water collection trough body is open, and a placement flange is fixed to the upper inner circumference of the water collection trough body.
[0007] The filter cover is placed horizontally at the top opening of the water collection tank body in a vertical sliding fit. The bottom four corners of the filter cover are equipped with a support assembly, and the bottom surface of the support assembly is in contact with the top surface of the placement flange. The support assembly is used to support the filter cover in the top opening of the water collection tank body.
[0008] Preferably, the lower part of the water collection tank body is connected to a funnel-shaped water collection hopper, and the bottom surface of the water collection hopper is vertically and fixedly connected to a drain pipe.
[0009] Preferably, the filter cover plate is provided with multiple water filtration holes evenly distributed.
[0010] Preferably, each of the raised support components includes a support shaft and a pad. The support shaft is vertically fixed at each of the four corners of the bottom surface of the filter cover plate, and several bearing seats are coaxially rotatably installed on the periphery of each support shaft. The number of pads corresponds to the number of support shafts, and one end of each pad is rotatably connected to the support shaft through the corresponding bearing seat. At the same time, the bottom surface of each pad contacts and abuts against the top surface of the placement flange.
[0011] Preferably, the horizontal cross-sectional shape of the pads is a waist-shaped hole, and the support shaft is coaxial with one end of the corresponding pad. The other end of the pad can expose the edge of the filter cover by rotating around the support shaft.
[0012] Preferably, the number of bearing seats of the support shaft is two and they are located at the upper and lower positions of the corresponding support shaft, and the top surface of the pad is lower than the bottom surface of the filter cover plate.
[0013] Preferably, friction pads are coaxially fixed to the top surface of the pad at the ends away from the support shaft. The friction pads are rubber pads, and the thickness of the friction pads is greater than the distance between the top surface of the pad and the bottom surface of the filter cover plate.
[0014] Preferably, the bottom surface of each pad is covered with a cushioning pad made of cushioning material, and the bottom surface of each cushioning pad is in contact with the top surface of the placement flange.
[0015] In practical application of the bridge deck drainage device described above, during daily drainage, the raised support components are assembled and installed at the four corners of the bottom surface of the filter cover. By rotating the pads of the raised support components around the support axis until they are completely below the bottom surface of the filter cover, the filter cover is supported and placed in the top opening of the water collection tank body by the contact between the bottom surface of the pads and the top surface of the placement flange. This method of supporting the filter cover in the top opening of the water collection tank body is simple and easy to implement, facilitating the sealing of the filter cover in the top opening of the water collection tank body to achieve the filtration function. When extreme weather conditions require the top opening of the water collection tank body to be opened, the operator lifts the filter cover away from the top opening of the water collection tank body, thus opening the top opening. Then, the pads rotate around the support axis to support the filter cover. The support shaft rotates to be offset from the bottom surface of the filter cover and exposes the edge of the filter cover. Then, by using the outer ends of the bottom surfaces of the pads at the four corners to contact the outer perimeter of the top of the water collection tank body, the filter cover can be raised and supported above the top of the water collection tank body. This facilitates the removal of the filter cover, allowing the top of the water collection tank body to be opened, thus accelerating the discharge of accumulated water. This meets the needs of bridge water discharge in extreme weather conditions. It also facilitates the use of the filter cover to cover the top opening of the water collection tank body to prevent accidental falling objects from getting stuck. Since the bottom of the water collection tank body is fixedly connected to the funnel-shaped water collection hopper, the water falling into the water collection tank body can flow downwards and be discharged through the drain pipe, which helps to ensure that the water collection tank body has a good and stable water discharge effect.
[0016] The beneficial effects are as follows: 1. The present invention has a raised support assembly installed at the four corners of the bottom surface of the filter cover plate. After the pad of the raised support assembly rotates around the support shaft and is completely located below the bottom surface of the filter cover plate, the filter cover plate can be supported and placed in the top opening of the water collection tank body by the bottom surface of the pad contacting the top surface of the placement flange. The method of supporting the filter cover plate in the top opening of the water collection tank body is simple and easy to implement, and it is convenient to seal the filter cover plate in the top opening of the water collection tank body to achieve the water filtration function.
[0017] 2. When the filter cover is raised away from the top opening of the water collection tank body, the top opening of the water collection tank body is opened. The pads are rotated around the support shaft until they are offset from the bottom surface of the filter cover and the edge of the filter cover is exposed. Then, the bottom surfaces of the pads at the four corners contact the bottom surface of the top outer perimeter of the water collection tank body. This can raise and support the filter cover above the top of the water collection tank body. This makes it easy to remove the filter cover and open the top of the water collection tank body to accelerate the drainage of accumulated water. It also makes it easy to prevent accidental falling objects from getting stuck by covering the top opening of the water collection tank body with the filter cover.
[0018] 3. A funnel-shaped water collection hopper is fixedly connected to the bottom of the water collection tank body. The water collection hopper allows the water falling into the water collection tank body to flow downwards and be discharged through the drain pipe, which helps to ensure that the water collection tank body has a good and stable water discharge effect.

[0029] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0030] See Figures 1-7 As shown, this utility model provides a bridge deck drainage device, including a water collection tank body 2 and a filter cover plate 1. The top of the water collection tank body 2 is open. A placement flange 201 is fixedly fixed to the upper part of the inner circumference of the water collection tank body 2. The filter cover plate 1 is placed flat on the top opening of the water collection tank body 2 in a vertical sliding fit. A raised support assembly 5 is assembled and installed at each of the four corners of the bottom surface of the filter cover plate 1, and the bottom surface of the raised support assembly 5 contacts and abuts against the top surface of the placement flange 201, so as to support the filter cover plate 1 in the top opening of the water collection tank body 2 through the raised support assembly 5. Specifically, the raised support assembly 5 includes a support shaft 502 and a pad 501. The support shaft 502 is vertically fixed at each of the four corners of the bottom surface of the filter cover plate 1, and several bearing seats 503 are coaxially rotatably installed on the periphery of the support shaft 502. The number of pads 501 corresponds to the number of support shafts 502, and one end of each pad is connected to the corresponding bearing seat 503. 03 is rotatably connected to the support shaft 502, and the bottom surface of the pad 501 is in contact with the top surface of the placement flange 201. The purpose of this arrangement is that, firstly, by raising the pad 501 of the support assembly 5 and rotating it around the support shaft 502 until it is completely below the bottom surface of the filter cover plate 1, the bottom surface of the pad 501 contacts the top surface of the placement flange 201, which can support the filter cover plate 1 in the top opening of the water collection tank body 2. When the filter cover plate 1 is raised away from the top opening of the water collection tank body 2, and the top opening of the water collection tank body 2 is opened, the pad 501 rotates around the support shaft 502 until it is offset from the bottom surface of the filter cover plate 1 and the edge of the filter cover plate 1 is exposed. Then, by using the bottom surfaces of the pads 501 at the four corners to contact the bottom surface of the top outer perimeter of the water collection tank body 2, the filter cover plate 1 can be raised and supported above the top of the water collection tank body 2, so as to raise and support the filter cover plate 1 at a certain height above the top of the water collection tank body 2.
[0031] See Figures 1-4As shown, the following optimizations were made to the water collection tank body 2, the filter cover plate 1, and the raised support assembly 5. Specifically, for the water collection tank body 2 and the filter cover plate 1, the lower part of the water collection tank body 2 is connected to a funnel-shaped water collection hopper 3, and the bottom surface of the water collection hopper 3 is vertically connected to a drain pipe 4. This arrangement facilitates the downward flow of water falling into the water collection tank body 2 through the water collection hopper 3, which is then discharged through the drain pipe 4. Optionally, the filter cover plate 1 is provided with multiple evenly distributed filter holes 101 to intercept dirt in the water entering the water collection tank body 2. Specifically, regarding the support assembly 5, the horizontal cross-sectional shape of the pads 501 is a waist-shaped hole, and the support shafts 502 are all coaxial with one end of the corresponding pad 501. The other end of the pad 501 can be exposed at the edge of the filter cover plate 1 by rotating around the support shaft 502. This arrangement ensures that the design of the pads 501 meets the usage requirements and avoids the situation where the pads 501 cannot be placed on the ground outside the top opening of the water collection tank body 2. Optionally, the support shaft 502 has two bearing seats 503, located above and below the corresponding support shaft 502, and the top surface of the pads 501 is lower than the bottom surface of the filter cover plate 1. This arrangement allows the pads 501 to be stably connected to the support shaft 502 by means of the bearing seats 503. Friction pads 504 are coaxially fixed to the top surface of the pad 501 at the end furthest from the support shaft 502. The friction pads 504 are rubber pads, and their thickness is greater than the distance between the top surface of the pad 501 and the bottom surface of the filter cover plate 1. This arrangement facilitates the compression and deformation of the friction pads 504 between the top surface of the pad 501 and the bottom surface of the filter cover plate 1, preventing the pad 501 from moving erratically in the retracted state and ensuring that the bottom of the pad 501 contacts the top surface of the placement flange 201. Furthermore, the bottom surface of the pad 501 is covered and fixed with a cushioning liner 505 of cushioning material, and the bottom surface of the cushioning liner 505 contacts the top surface of the placement flange 201. This allows the cushioning liner 505 to directly contact the top surface of the placement flange 201, providing cushioning support for the placement and use of the filter cover plate 1.
[0032] With the above structure, in practical use, during daily drainage, since the four corners of the bottom surface of the filter cover plate 1 are all equipped with lifting support components 5, the pads 501 of the lifting support components 5 rotate around the support shaft 502 until they are completely below the bottom surface of the filter cover plate 1. The bottom surface of the pads 501 contacts the top surface of the placement flange 201, which supports the filter cover plate 1 in the top opening of the water collection tank body 2. The method of supporting the filter cover plate 1 in the top opening of the water collection tank body 2 is simple and easy to implement, making it easy to seal the filter cover plate 1 in the top opening of the water collection tank body 2 to achieve the water filtration function. When extreme weather occurs and it is necessary to open the top opening of the water collection tank body 2, the operator raises the filter cover plate 1 away from the top opening of the water collection tank body 2, thus opening the top opening of the water collection tank body 2. Then, the pads 501 rotate around the support shaft... The filter cover 1 is offset from the bottom surface of the filter cover 1 and its edge is exposed. The filter cover 1 is raised and supported above the top of the water collection tank body 2 by means of the bottom outer end of the pads 501 at the four corners. This makes it easy to remove the filter cover 1 and open the top of the water collection tank body 2 to accelerate the discharge of water. This meets the needs of bridge water discharge in extreme weather. It also makes it easy to prevent accidental falling objects from falling in by covering the top opening of the water collection tank body 2 with the filter cover 1. Since the bottom of the water collection tank body 2 is fixedly connected to the funnel-shaped water collection hopper 3, the water that falls into the water collection tank body 2 can flow downward and be discharged through the drain pipe 4. This helps to ensure that the water collection tank body 2 has a good and stable water discharge effect.
[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
