Description

Technical Field

[0001] This utility model relates to the field of water diversion engineering technology, specifically a trash rack for water diversion projects with rapid maintenance function. Background Technology

[0002] Trash grates are mainly used to intercept debris such as aquatic plants, driftwood, plastic bags, and woven bags carried in water flow, preventing these contaminants from entering subsequent water treatment systems or pumping stations and causing blockages or damage. In water diversion projects, trash grates can protect key equipment such as water pumps and valves from damage by contaminants, thereby extending the service life of the equipment and reducing maintenance costs.

[0003] Current trash racks generally face a practical challenge during regular inspections or maintenance: to perform necessary cleaning, inspection, or replacement of damaged parts, the entire trash rack structure usually needs to be completely removed from the hydroelectric power station intake or the relevant water area. While this step is crucial to ensuring the long-term effective operation of the trash rack, it also brings a significant side effect: during the period when the trash rack is removed for maintenance, floating debris, garbage, and other debris in the river or waterway will no longer be effectively intercepted, allowing various types of debris that were previously effectively blocked to continue moving freely with the water flow. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a trash rack for water diversion projects with rapid maintenance capabilities, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a trash rack for water diversion projects with rapid maintenance function, comprising side plates respectively installed on both sides of the water intake, and the two side plates are connected to the same rotating shaft by bearings inside the side plates. A sleeve is sleeved on the outside of the rotating shaft, and two bearing plates are installed on the upper and lower sides of the sleeve.

[0006] The opposite sides of the upper and lower supporting plates each form a recessed groove, and a trash rack body is inserted into the inside of each of the two recessed grooves. The trash rack body is connected to the supporting plate by bolts.

[0007] One of the side plates is provided with a drive assembly on the side away from the main body of the trash rack for driving the rotating shaft to rotate;

[0008] The drive assembly includes a mounting plate installed on one of the side plates away from the main body of the trash rack. Two bearing seats are provided on the upper surface of the mounting plate. A worm gear is rotatably connected between the opposite sides of the two bearing seats. A worm wheel that meshes with the worm gear is sleeved on the outside of the rotating shaft.

[0009] Furthermore, the two trash rack bodies are located on the same vertical plane.

[0010] Furthermore, the main body of the trash rack is attached between the two opposite sides of the two side plates.

[0011] Furthermore, a handle connected to the worm gear drive is provided on the bearing housing.

[0012] Furthermore, a limit component is also provided on the side plate and on the same side as the drive component;

[0013] The limiting component includes a sliding plate inside the side plate, and a screw threadedly connected to the plate on the side of the side plate away from the main body of the trash rack.

[0014] Furthermore, the upper cross-section of the card plate is U-shaped, and the card plate is attached to the front and rear sides of the main body of the trash rack.

[0015] Furthermore, corresponding to the card plate, a sliding groove is provided inside the side plate for the card plate to slide left and right.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. This trash rack for water diversion projects with rapid maintenance function, through the design of the drive component, can easily drive the rotating shaft to rotate, thereby realizing the replacement of the main body of the trash rack. This allows the main body of the trash rack that needs maintenance to be moved to the water body, facilitating rapid maintenance by maintenance personnel and greatly improving maintenance efficiency. Moreover, during the maintenance process, another trash rack body continues to perform the interception task in the water body, ensuring the continuous interception of floating objects, garbage and other debris in the river channel, without affecting the normal operation of the water diversion project.

[0018] 2. This trash rack for water diversion projects, equipped with a rapid maintenance function, features a limit component design that effectively restricts the position of the main body of the trash rack through the cooperation of the clamping plate and the screw, preventing it from shaking or shifting due to water flow impact or other external forces during the interception process, thus improving overall stability. In addition, the meshing of the worm and worm wheel has self-locking properties, which can prevent accidental rotation caused by external factors to a certain extent, ensuring smooth operation and safety.

[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. 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.

[0024] Please see Figure 1-3 This embodiment provides a trash rack for water diversion projects with rapid maintenance capabilities, which increases the convenience of trash rack maintenance and ensures continuous interception of floating objects, garbage and other debris in the river during the maintenance process.

[0025] Specifically, it includes side plates 1 installed on both sides of the water inlet. Inside the two side plates 1, a bearing is connected to the same rotating shaft 2. A sleeve 3 is sleeved on the outside of the rotating shaft 2. Two bearing plates 4 are installed on the upper and lower sides of the sleeve 3. The opposite sides of the upper and lower bearing plates 4 are recessed to form a placement groove. A trash rack body 5 is inserted into the two placement grooves. The trash rack body 5 is connected to the bearing plate 4 by bolts. A drive assembly 6 is provided on the side of one of the side plates 1 away from the trash rack body 5 to drive the rotating shaft 2 to rotate.

[0026] In actual use, when it is necessary to inspect the main body 5 of the trash rack located inside the water body, the drive component 6 is used to drive the rotating shaft 2 to rotate, thereby causing the sleeve 3 on the outside of the rotating shaft 2 and the bearing plates 4 on both sides of the upper side to rotate simultaneously. This causes the main body 5 of the trash rack located inside the water body to move to the top of the water body, while the trash rack main body 5 originally located above the water body moves to the inside of the water body to continue intercepting trash. Both trash rack main bodies 5 rotate 180 degrees at the same time, at which point the trash rack main body 5 that has moved to the top of the water body can be maintained.

[0027] In detail, in order to facilitate the rotation of the rotating shaft 2, the drive assembly 6 in this embodiment includes a mounting plate 601 installed on one of the side plates 1 away from the main body 5 of the trash rack. Two bearing seats 602 are provided on the upper surface of the mounting plate 601. A worm gear 603 is rotatably connected between the opposite sides of the two bearing seats 602. A worm wheel 604 that meshes with the worm gear 603 is sleeved on the outside of the rotating shaft 2.

[0028] In actual use, the worm gear 603 is rotated, which in turn drives the inner shaft 2 to rotate. At the same time, the outer sleeve 3 of the shaft 2 and the upper and lower bearing plates 4 rotate simultaneously, thereby replacing the position of the upper and lower trash rack bodies 5, so as to facilitate the inspection and maintenance of the trash rack bodies 5 in the original water body.

[0029] In addition, the meshing of the worm 603 and the worm wheel 604 has a self-locking property, which can prevent accidental rotation caused by external factors to a certain extent, thus ensuring the smoothness and safety of operation.

[0030] It should be noted that the two main bodies 5 of the trash rack are located on the same vertical plane, and the main bodies 5 of the trash rack are attached to the opposite side of the two side plates 1.

[0031] Furthermore, in order to facilitate the rotation of the worm 603, a handle that is connected to the worm 603 in transmission is provided on the bearing seat 602 in this embodiment. The handle is provided so that the operator can drive the worm 603 to rotate.

[0032] Furthermore, in order to improve the stability of the trash rack body 5 during the interception process, a limiting component 7 is also provided on the side plate 1 on the same side as the drive component 6 in this embodiment; the limiting component 7 includes a locking plate 701 inside the sliding side plate 1, and a screw 702 that is threadedly connected to the locking plate 701 is rotatably connected to the side of the side plate 1 away from the trash rack body 5.

[0033] In actual use, by rotating the screw 702, the clamping plate 701 is pushed towards the trash rack body 5, so that the clamping plate 701 fits against the front and rear sides of the trash rack body 5, thereby restricting the position of the trash rack body 5 and further improving the stability of the trash rack body 5 during the interception process.

[0034] In detail, the upper cross-section of the card plate 701 in this embodiment is U-shaped, and the card plate 701 is attached to the front and rear sides of the main body 5 of the trash rack. Corresponding to the card plate 701, a sliding groove is provided inside the side plate 1 for the card plate 701 to slide left and right.

[0035] In actual setup, the card plate 701 adopts a U-shaped design so that it can better fit the shape of the left side of the main body 5 of the trash rack. At the same time, the opening of the sliding groove also ensures that the card plate 701 can slide smoothly left and right inside the side plate 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
