Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy trash racks, specifically an inverted triangular trash guide structure for water conservancy trash racks. Background Technology

[0002] A hydraulic debris barrier is a frame structure installed before the water inlet to block debris such as aquatic plants and driftwood carried by the water flow, ensuring the safe operation of hydraulic structures and turbine generators or pumps. Existing hydraulic debris barriers on the market consist of a frame, horizontal partitions, and bars, supported by concrete piers. They are typically made of steel and have a rectangular structure. The top and bottom of the bars are relatively flat, making it easy for debris to accumulate on both sides, especially when the water flow is slow or there is a large amount of debris. Furthermore, because rectangular debris barriers have relatively weak guiding effect on the water flow, the change in flow direction and velocity is minimal when the water passes through them. This prevents debris from moving in a specific direction and path, thus preventing it from concentrating in a specific area and making subsequent debris removal very difficult. Utility Model Content

[0003] The purpose of this utility model is to provide an inverted triangular debris guiding structure for hydraulic debris barriers, in order to solve the problem mentioned in the background art that the rectangular debris barrier structure currently used in the market cannot guide the water flow when intercepting debris, making subsequent cleaning work troublesome.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an inverted triangular guide structure for water conservancy trash racks, including a fixed base plate, which is plate-shaped and has an inclined structure on one side to assist water flow.

[0005] The first guide component is inclined and there are two sets of it symmetrically arranged for guiding sediment. The bottom of the first guide component is connected to the top of the fixed base plate.

[0006] A connecting seat is connected to the top of the first guide component. A rotating component is provided at the top of the connecting seat. The bottom of the rotating component is connected to the second guide component. The two sets of the first guide component and the second guide component form an inverted triangular structure when viewed from above.

[0007] Preferably, the two sets of the first guide components are arranged in a "V" shape and include an inner baffle plate, an outer baffle plate, a hollow groove and a connecting plate. The inner baffle plate and the outer baffle plate are arranged sequentially from the inside to the outside. The bottom of the inner baffle plate and the outer baffle plate are connected by the connecting plate. The bottom of the connecting plate is connected to the top of the fixed base plate. A hollow groove is provided in the middle of the inner baffle plate and the outer baffle plate.

[0008] Preferably, both the inner and outer debris barriers are provided with a through-hole mesh structure for debris interception.

[0009] Preferably, the second guiding component includes a guide filter plate, a rotating cylinder, and a moving wheel. The top end of the rotating cylinder is connected to the rotating component, and the guide filter plate is provided on the outer side of the rotating cylinder. The moving wheel is provided at the bottom of the guide filter plate near the top end, and the moving wheel rolls above the fixed base plate.

[0010] Preferably, the connecting seat is integrally installed with the bottom of the first guide assembly, and the top of the connecting seat is provided with a "U"-shaped groove. The interior of the "U"-shaped groove engages with the rotating cylinder, and the distance between the two symmetrically arranged connecting seats is twice the length of the guide filter plate.

[0011] Preferably, the rotating assembly includes a rotating motor and a rotating shaft, the bottom of the rotating motor is coaxially connected to the rotating shaft, and the bottom of the rotating shaft is connected to the rotating cylinder through a connecting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the water conservancy trash rack uses an inverted triangular trash guide structure;

[0013] 1. It is equipped with two first guide components, which are arranged in an inverted V-shape. The V-shape is designed to better guide the water flow, so that the water can flow in a certain direction and path when passing through the trash rack. The trash is more easily intercepted in the middle of the V-shape, thus improving the interception efficiency.

[0014] 2. A second guide component is provided, which can rotate under the action of the rotating component. By rotating the second guide component to a horizontal state, the top of the V-shaped first guide component can be sealed, which facilitates the unified cleaning of the dirt accumulated in the V-shaped first guide component. When the second guide component is rotated to the inclined structure, it can also reduce the lateral pressure of water flow on the trash rack, enhance the stability of the entire trash rack structure, and improve the service life of the entire trash rack.

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: an inverted triangular guide structure for water conservancy trash racks, including a fixed base plate 1, which is plate-shaped and has an inclined structure on one side to assist water flow.

[0024] The first guide component 2 is inclined and there are two sets of it symmetrically arranged for guiding sediment. The bottom of the first guide component 2 is connected to the top of the fixed base plate 1.

[0025] The connecting seat 4 is connected to the top of the first guide component 2. A rotating component 5 is provided at the top of the connecting seat 4. The bottom of the rotating component 5 is connected to the second guide component 3. The two sets of the first guide component 2 and the second guide component 3 form an inverted triangular structure when viewed from above.

[0026] This application provides an inverted triangular debris-guiding structure for hydraulic debris barriers. Specifically, during use, the entire fixed base plate 1, along with its top first guide component 2, is set inside the base groove to intercept the debris. When the water flows through, it is first guided by the second guide component 3, and then reaches the position of the first guide component 2 for guidance and debris interception. Finally, the aquatic plants, driftwood, and other debris carried in the water flow will be blocked in the middle of the two first guide components 2, completing the debris interception work.

[0027] Among them, according to Figure 2-4 As shown, the two sets of first guide components 2 are arranged in a "V" shape, and each includes an inner baffle plate 21, an outer baffle plate 22, a hollow groove 23, and a connecting plate 24. The inner baffle plate 21 and the outer baffle plate 22 are arranged sequentially from the inside to the outside. The bottoms of the inner baffle plate 21 and the outer baffle plate 22 are connected by the connecting plate 24. The bottom of the connecting plate 24 is connected to the top of the fixed base plate 1. A hollow groove 23 is provided in the middle of the inner baffle plate 21 and the outer baffle plate 22.

[0028] Both the inner and outer debris barriers 21 and 22 are provided with through-hole mesh structures for debris interception.

[0029] Specifically, when the first guide component 2 is performing the interception and guidance, the water carrying debris will first pass through the inner debris barrier 21 for initial debris interception. Then, the debris will initially accumulate between the two inner debris barrier 21s. After the water flows through the inner debris barrier 21s, it will reach the middle of the hollow trough 23, and then reach the position of the outer debris barrier 22 for discharge.

[0030] When too much debris accumulates in the middle of the inner baffle 21, it becomes blocked, preventing water from flowing through. Consequently, the water flowing through the outer side of the inner baffle 21 transitions in the middle of the hollow trough 23, allowing the water flow to redistribute within the hollow trough 23. This reduces localized water concentration and ensures that subsequent water flow can be fully discharged from the surface of the outer baffle 22, resulting in a more even flow through the outer baffle 22 and improved flow efficiency.

[0031] Furthermore, according to Figure 5-6 As shown, the second guide assembly 3 includes a guide filter plate 31, a rotating cylinder 32, and a moving wheel 33. The top end of the rotating cylinder 32 is connected to the rotating assembly 5, and the guide filter plate 31 is provided on the outer side of the rotating cylinder 32. The moving wheel 33 is provided at the bottom of the guide filter plate 31 near the top end, and the moving wheel 33 rolls above the fixed base plate 1.

[0032] The connecting seat 4 is integrally installed with the bottom of the first guide component 2. The top of the connecting seat 4 is provided with a "U"-shaped groove. The inside of the "U"-shaped groove engages with the rotating cylinder 32. The distance between the two symmetrically arranged connecting seats 4 is twice the length of the guide filter plate 31.

[0033] The rotating assembly 5 includes a rotating motor 51 and a rotating shaft 52. The bottom of the rotating motor 51 is coaxially connected to the rotating shaft 52, and the bottom of the rotating shaft 52 passes through the connecting seat 4 and is connected to the rotating cylinder 32.

[0034] Specifically, when it is necessary to clean the dirt accumulated in the middle of the first guide assembly 2, the rotary motor 51 can be controlled to rotate. When it rotates, the rotary shaft 52 will rotate. When the rotary shaft 52 rotates, it will drive the rotary cylinder 32 to rotate. As a result, when the rotary cylinder 32 rotates, it will drive the guide filter plate 31 to rotate. When both guide filter plates 31 are rotated to a horizontal state, the top openings of the two first guide assemblies 2 will be sealed. At this time, the dirt inside the inverted triangle space formed by the first guide assembly 2 and the second guide assembly 3 can be cleaned by an external cleaning device.

[0035] When the cleaning is completed and the lateral pressure of the water flow needs to be dispersed by the second guide component 3, it is only necessary to control the guide filter plate 31 to rotate into an inclined state towards the first guide component 2. Therefore, the inclined second guide component 3 can disperse the pressure of the flowing water.

[0036] In this application, a movable wheel 33 is provided at the bottom-to-top position of the guide filter plate 31. This ensures that the guide filter plate 31 can rotate and move more smoothly. Content not described in detail in this specification is prior art known to those skilled in the art.

[0037] 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.
