Description
Technical Field
[0001] The invention belongs to the technical field of water conservancy facilities, and in particular relates to a novel trash rack structure. Background Art
[0002] Trash racks are hydraulic devices used in water conservancy facilities to intercept aquatic plants, driftwood and other debris carried by water flow. They are installed at the water inlet. When the water flow speed is too high, the trash rack will swing back and forth in the rack groove, thus damaging the civil engineering structure. For this reason, people install limit devices and buffer devices on the trash rack.
[0003] like Figure 1 and 2 As shown, the existing buffer device is arranged on the front and rear sides of the end of the trash rack, and forms a buffer with the wall surface when the trash rack swings back and forth. The existing limit device is usually placed on the upstream side of the water flow, arranged on the same side as the grid bar, and occupies the position of the grid bar, so that the gap between the side grid bar and the end longitudinal beam is too large, and the dirt will leak through the gap; then the dirt will enter the gate slot along the gap, causing the gate slot to be blocked by water plants and other dirt, and finally causing the trash rack to be unable to open or close or difficult to open and close.
[0004] It can be seen that the existing trash rack has a relatively complex structure and has defects in practical applications. Summary of the invention
[0005] The object of the present invention is to provide a novel trash rack structure which can simplify the structure and realize the integration of limiting and buffering functions.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel trash rack structure, wherein side rails for installing the left and right sides of the trash rack are installed on both sides of the water inlet, and a bottom rail for supporting the trash rack is installed on the bottom, the side rails have front and rear side panels, and the inner side surfaces of the front and rear side panels are inclined limiting surfaces; side panels are arranged on the left and right sides of the trash rack, and limiting block plates are inclinedly arranged on the front and rear sides of the side panels, and a plurality of isolation protrusions arranged at intervals are arranged on the limiting block plates, and a limiting buffer block is installed between two adjacent isolation protrusions, and the top surface of the limiting buffer block is higher than the top surface of the isolation protrusion and can form a limiting contact with the corresponding inner side surface.
[0007] Furthermore, the surface of the limit buffer block is provided with a first mating surface, a second mating surface and a third mating surface which are sequentially transitionally connected, the first mating surface and the third mating surface are both arc surfaces, and the second mating surface is a plane matching the inner side surface.
[0008] Furthermore, the first mating surface includes a first arc surface and a second arc surface connected in sequence, the radius of the first arc surface is equal to the radius of the third mating surface, and the radius of the second arc surface is equal to the radius of the bottom fillet of the inner side surface.
[0009] Furthermore, the limit buffer block is adjustably mounted on the limit block plate.
[0010] Furthermore, a waist-shaped countersunk hole is provided on the limiting buffer block, and a threaded hole is provided on the limiting block plate between the two adjacent isolation protrusions, and the waist-shaped countersunk hole is connected to the threaded hole by a screw.
[0011] Furthermore, support ribs are provided between the side plates, the limiting block plates and the trash rack.
[0012] Furthermore, the buffer block is a nylon block or a rubber block.
[0013] Furthermore, a first anchor is provided on the back side of the side rail.
[0014] Furthermore, a mounting plate is provided at the bottom of the side rail, and the mounting plate is connected to the bottom rail via a fastener.
[0015] Furthermore, a second anchor is provided at the bottom of the bottom rail.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1) The present invention utilizes the cooperation between the side rails and the limiting buffer blocks to achieve the purpose of limiting and buffering the trash rack with a simpler structure. At the same time, since the limiting buffer structures are all located in the side rails, they do not occupy the effective area of the water-facing surface and the water-receiving surface of the trash rack. Therefore, the bars can cover the entire water-facing surface and the water-receiving surface more evenly, reducing the gaps and thus improving the trash intercepting capacity.
[0018] 2) The present invention can solve the problem of wear of the limit buffer block by replacing or adjusting the limit buffer block.
[0019] 3) The side rails and bottom rails in the present invention are directly made of readily available channel steels of corresponding specifications, and the materials are cheap and easily available, which can reduce the manufacturing cost and construction cost of the entire facility.
[0020] 4) The embedded parts (including the side rails and the bottom gauge) in the present invention are easy to manufacture, the installation accuracy is easy to control, and there is no need to reserve a trash rack door slot in the civil engineering. The first-stage casting is directly carried out, and the civil engineering is integrated to save construction time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] like Figures 3 to 10 As shown, the present invention provides a novel trash rack structure, with side rails 2 installed on both sides of the water inlet and a bottom rail 3 installed on the bottom.
[0033] The side rails 2 and the bottom rails 3 are both channel steels, wherein the side rails 2 are arranged vertically with their notches facing inward. The bottom rails 3 are arranged horizontally with their notches facing downward. As a preferred example, a first anchor 2.1 is arranged on the back of the side rails 2, and a second anchor 3.1 is arranged on the bottom of the bottom rails 3, and both the first anchor 2.1 and the second anchor 3.1 are steel bars. When fixing the side rails 2 and the bottom rails 3, a mounting plate 2.5 is arranged at the bottom of the side rails 2, and the mounting plate 2.5 is connected to the bottom rails 3 by fasteners 4. Both the bottom rails 3 and the side rails 2 are fixed by pre-embedded method after concrete pouring.
[0034] The side rail 2 has front and rear side plates 2.2. The inner side surfaces 2.3 of the front and rear side plates 2.2 are inclined limiting surfaces. The inner side surfaces 2.3 are transitionally connected to the bottom surface of the groove through fillets 2.4.
[0035] The trash rack 1 is provided with side panels 5 on the left and right sides, and the front and rear sides of the side panels 5 are inclinedly provided with limit block panels 5.1, and the limit block panels 5.1 are provided with a plurality of spaced isolation protrusions 5.2, and a limit buffer block 6 is installed between two adjacent isolation protrusions 5.2. The function of the isolation protrusion 5.2 is to provide guide adjustment for the limit buffer block 6.
[0036] The top surface of the limit buffer block 6 is higher than the top surface of the isolation protrusion 5.2. When the trash rack 1 swings to one side, the side plate 5 on that side will approach the side rail 2, so that the limit buffer block 6 contacts the inner side surface 2.3, thereby limiting the side of the trash rack. Since the limit buffer block 6 has a buffering effect, it will buffer the impact when in contact.
[0037] The surface of the limit buffer block 6 is provided with a first mating surface 6.1, a second mating surface 6.2 and a third mating surface 6.3 which are sequentially transitionally connected. The first mating surface 6.1 and the third mating surface 6.3 are both cambered surfaces, and the second mating surface 6.2 is a plane matching the inner side surface 2.3. The purpose of setting the first mating surface 6.1 and the third mating surface 6.3 as cambered surfaces is to prevent the far end and the near end of the surface of the limit buffer block 6 from generating stress concentration when contacting the inner side surface 2.3 when the trash rack 1 is tilted, thereby avoiding the contact part from being squeezed and damaged.
[0038] As a preferred example, the first mating surface 6.1 includes a first arc surface and a second arc surface connected in sequence, the radius R1 of the first arc surface is equal to the radius R3 of the third mating surface 6.3, and the radius R2 of the second arc surface is equal to the radius R4 of the bottom fillet of the inner side surface 2.3. After the limit is formed, the second arc surface and the bottom fillet of the inner side surface 2.3 are just matched and contacted, and the purpose of this is to apply a resistance to the second arc surface through the fillet, so as to reduce the friction between the second mating surface 6.1 and the inner side surface 2.3 and reduce the wear of the second mating surface 6.1.
[0039] As a preferred example, in order to avoid limit failure due to wear, the limit buffer block 6 is adjustably mounted on the limit block plate 5.1. Specifically, a waist-shaped countersunk hole is provided on the limit buffer block 6, and a threaded hole is provided on the limit block plate 5.1 between two adjacent isolation protrusions 5.2, and the waist-shaped countersunk hole is connected to the threaded hole by a screw 7. Since the limit block plate 5.1 is tilted, when the surface of the limit buffer block 6 is worn, it is adjusted backward to make the entire second mating surface 6.1 more outward to compensate for the mating error caused by wear. It should be noted that when the limit buffer block 6 is severely worn and cannot realize its function by adjusting the position, it can be directly replaced, or it can be replaced when wear first occurs.
[0040] Since the side plate 5 is subjected to the inward force of the side rail 2 when limiting, in order to improve the compression resistance of the side plate 5, a plurality of supporting ribs 5.4 are arranged between the side plate 5, the limiting block plate 5.1 and the trash rack 1.
[0041] As a preferred example, the buffer block 6 is a nylon block or a rubber block, which has better wear resistance and extrusion resistance than metal parts, and is low in cost and easy to manufacture.
[0042] The present invention utilizes the cooperation between the side rails and the limiting buffer blocks to achieve the purpose of limiting and buffering the trash rack with a simpler structure. At the same time, since the limiting buffer structures are all located in the side rails, they do not occupy the effective area of the water-facing and water-receiving surfaces of the trash rack, so the bars can cover the entire water-facing and water-receiving surfaces more evenly, reducing gaps and thus improving the trash interception capacity. The present invention is easy to install and manufacture, and can achieve the trash interception effect of conventional trash racks. Not only is the structure of the trash rack itself simple and innovative, but the civil engineering structure matched with the trash rack also becomes convenient and simple in design and construction.
[0043] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
[0044] It should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified and replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
