Description

Technical Field

[0001] This utility model relates to the technical field of river pollution interception equipment, and in particular to a pollution interception grid for water conservancy projects. Background Technology

[0002] A trash rack consists of a frame, horizontal partitions, and bars, and is supported on a concrete pier wall. It is generally made of steel, and the spacing of the bars depends on the size and amount of trash and the application requirements.

[0003] A search revealed that Chinese patent application number 201720917045.4 discloses "a trash rack, the key technical points of which are: side beams supported on both sides of the pier, a top beam fixed to the top of the two side beams, a bottom beam fixed to the bottom of the two side beams, and rack plates spaced apart between the two side beams. The rack plates are vertically arranged along the length of the side beams, and the upper and lower ends of the rack plates are welded to the top beam and the bottom beam, respectively. It also includes a cleaning device, which includes a cleaning rod located on the side of the rack plate away from the inlet and close to the bottom beam and arranged along the length of the bottom beam, and a driving device for driving the cleaning rod to move up and down along the height of the rack plate." However, when the trash rack is used, because the bottom of the trash rack is flat, while the riverbed is not flat, a gap will be left between the trash rack and the lowest point of the riverbed. River garbage will flow out through this gap, resulting in incomplete interception of river garbage. Therefore, in order to solve this problem, a trash rack for water conservancy projects is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a trash rack for water conservancy projects.

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

[0006] A trash rack for water conservancy projects includes a strip plate with several through holes at the top, arranged horizontally. An internally threaded sleeve is installed within each through hole, and a threaded rod is installed within the internal thread of the sleeve. A top plate is connected to the top of the strip plate via a fixing frame. Two wire rope winders are symmetrically installed at the bottom of the top plate, each winder having wire rope wound around it. The bottom ends of the two wire ropes are connected to a baffle. The top of the baffle has several circular openings, each corresponding to one of the through holes. Several threaded rods are located within each of the circular openings.

[0007] Preferably, a fixing plate is installed on both sides of the strip plate, and an mounting plate is installed on the side of the fixing plate away from the strip plate, with a mounting hole on the top of the mounting plate.

[0008] Preferably, a rotating block is installed at the top of the threaded rod, and a drill bit is installed at the bottom of the threaded rod.

[0009] Preferably, the top of the baffle is equipped with several baffles at an angle, and the baffles are divided into two groups and symmetrically distributed on both sides of the threaded rod.

[0010] Preferably, two lifting rings are symmetrically installed on the top of the baffle, and the bottom ends of two steel wire ropes are respectively connected to the two lifting rings.

[0011] Preferably, the bottom end of the fixing frame is fixed to the top of the strip plate, and the top end of the fixing frame is fixed to the side of the top plate.

[0012] Preferably, the threaded rod is located between the two lifting rings, and the strip plate is located between the two wire ropes.

[0013] Preferably, an mounting plate is installed at the bottom end of the threaded rod, and the drill bit is installed at the bottom of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the drill bits at the bottom of several threaded rods are drilled into the riverbed, so that the several threaded rods form a trash rack to intercept garbage in the river. Since the drill bits at the bottom of several threaded rods are all drilled into the riverbed, the garbage in the river can be completely intercepted. This avoids the problem of garbage flowing out through gaps between the bottom of the traditional trash rack and the riverbed. It can comprehensively intercept garbage in the river and improve the comprehensiveness of garbage interception in the river.

[0016] 2: In this utility model, the wire rope reel can wind the wire rope onto the reel, which can then pull the lifting ring and the baffle to move upward. The upward movement of the baffle will cause the garbage intercepted on the baffle to move upward, thus causing the garbage intercepted on the baffle to float to the surface of the river. At this time, the garbage intercepted on the baffle can be cleaned up. This allows for convenient cleaning of the garbage intercepted on the baffle, ensuring that the gaps between the threaded rods are not blocked by garbage. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A trash rack for water conservancy projects includes a strip plate 1. The top of the strip plate 1 has several through holes 17 arranged horizontally. An internal threaded sleeve 12 is installed in the through hole 17. A threaded rod 13 is installed in the internal thread of the internal threaded sleeve 12. The top of the strip plate 1 is connected to a top plate 5 through a fixing frame 4. Two wire rope winders 6 are symmetrically installed at the bottom of the top plate 5. Wire ropes 7 are wound on both wire rope winders 6. The bottom ends of the two wire ropes 7 are connected to a baffle 9. The top of the baffle 9 has several circular openings 11. The positions of the circular openings 11 correspond one-to-one with the positions of the through holes 17. The threaded rods 13 are located in the circular openings 11 respectively.

[0025] As a technical optimization of this utility model, fixing plates 2 are installed on both sides of the strip plate 1, and mounting plate 3 is installed on the side of the fixing plate 2 away from the strip plate 1. Mounting plate 3 has mounting holes 16 on its top. The fixing plates 2 can facilitate the connection between the mounting plate 3 and the strip plate 1, and the mounting holes 16 can facilitate the fixing of the mounting plate 3, thereby facilitating the fixing of the strip plate 1.

[0026] As a technical optimization of this utility model, a rotating block 14 is installed at the top of the threaded rod 13, and a drill bit 15 is installed at the bottom of the threaded rod 13. The rotating block 14 can facilitate the rotation of the threaded rod 13.

[0027] As a technical optimization of this utility model, a number of stop bars 10 are installed at the top of the baffle 9 at an angle, and the number of stop bars 10 are divided into two groups and symmetrically distributed on both sides of the threaded rod 13.

[0028] As a technical optimization of this utility model, two lifting rings 8 are symmetrically installed on the top of the baffle 9, and the bottom ends of two steel wire ropes 7 are respectively connected to the two lifting rings 8. The lifting rings 8 can facilitate the connection between the bottom ends of the steel wire ropes 7 and the baffle 9.

[0029] As a technical optimization of this utility model, the bottom end of the fixing frame 4 is fixedly connected to the top of the strip plate 1, and the top end of the fixing frame 4 is fixedly connected to the side of the top plate 5.

[0030] As a technical optimization of this utility model, the threaded rod 13 is located between the two lifting rings 8, and the strip plate 1 is located between the two wire ropes 7.

[0031] As a technical optimization of this utility model, an mounting plate is installed at the bottom end of the threaded rod 13, and the drill bit 15 is installed at the bottom of the mounting plate. The mounting plate facilitates the connection between the drill bit 15 and the bottom end of the threaded rod 13, making it easier to install the drill bit 15 at the bottom end of the threaded rod 13.

[0032] When this utility model is in use, if it is necessary to intercept debris in a river, the strip plate 1 is installed in the middle of the river through the mounting holes 16 on the two mounting plates 3. Rotating the rotating block 14 will rotate the threaded rod 13. The threaded rod 13 rotates in the inner threaded sleeve 12, which causes the bottom end of the threaded rod 13 to drive the drill bit 15 down until the drill bit 15 drills into the riverbed. By using the drill bits 15 at the bottom ends of several threaded rods 13 to drill into the riverbed, several threaded rods 13 form a debris barrier to intercept the garbage in the river. Since the drill bits 15 at the bottom ends of several threaded rods 13 all drill into the riverbed, the garbage in the river can be completely intercepted. This avoids the problem of garbage flowing out through gaps between the bottom of the traditional debris barrier and the riverbed. It can comprehensively intercept the garbage in the river and improve the comprehensiveness of garbage interception in the river. The depth of the drill bit 15 can be adjusted according to the depth of the riverbed by rotating the threaded rod 13.

[0033] Furthermore, the garbage intercepted by several threaded rods 13 falls onto the baffle 9, and the baffle rods 10 installed on the baffle 9 intercept the garbage. When a large amount of garbage is intercepted on the baffle 9, two wire rope reels 6 are activated simultaneously. The wire rope reels 6 can wind the wire rope 7 onto the wire rope reels 6, and the wire rope 7 can pull the lifting ring 8 and the baffle 9 upward. The upward movement of the baffle 9 can also move the garbage intercepted on the baffle 9 upward, so that the garbage intercepted on the baffle 9 floats out of the river as the baffle 9 moves upward. At this time, the garbage intercepted on the baffle 9 can be cleaned up, which can easily clean up the garbage intercepted on the baffle 9 and ensure that the gaps between the several threaded rods 13 are not blocked by garbage.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
