[0023] This utility model provides a novel water source heat pump water intake head, the specific implementation of which is combined with Figures 1 to 4 Please provide a detailed explanation. For example... Figure 1 and Figure 2 As shown, the water intake head includes a base plate 1, a first guide side plate 2, a second guide side plate 3, a front baffle 4, a rear baffle 5, a top plate 6, a pipe body 7, a grid 8, a sand discharge port 9, and a sedimentation inclined plate 10. These components are connected by welding or bolts to form a complete structure, and the positional relationship and connection method between the components are described below.
[0024] The base plate 1 is placed horizontally at the bottom of the water intake head to support the entire device and bear the sediment deposited as the water flows through. Multiple sand discharge ports 9 are evenly distributed in the central area of the base plate 1; each sand discharge port 9 is a rectangular opening. The design of the sand discharge ports 9 allows the sediment deposited on the base plate 1 to be discharged from the cavity by gravity. The two sides of the base plate 1 are welded and fixed to the lower edges of the first guide plate 2 and the second guide plate 3, respectively, using a full welding process to ensure sealing. The front and rear ends of the base plate 1 are welded and fixed to the lower edges of the front baffle 4 and the rear baffle 5, respectively, forming the bottom boundary of the closed cavity.
[0025] The top plate 6 horizontally covers the top of the cavity, and its dimensions are the same as the bottom plate 1. The two sides of the top plate 6 are welded and fixed to the upper edges of the first guide side plate 2 and the second guide side plate 3, respectively, while the front and rear ends are welded and fixed to the upper edges of the front baffle 4 and the rear baffle 5, respectively. The welding method of the top plate 6 also adopts the full welding process to ensure the sealing of the top of the cavity and the overall strength.
[0026] The first guide plate 2 and the second guide plate 3 are symmetrically arranged on the left and right sides of the cavity, both made of steel plates. The cross-sectional shape of the first guide plate 2 and the second guide plate 3 gradually narrows from the side away from the sedimentation inclined plate 10, forming a tapered structure. This design allows the water flow to be guided and accelerated after entering the cavity, thereby reducing the probability of sediment deposition in the cavity. The inner surfaces of the first guide plate 2 and the second guide plate 3 are treated with anti-corrosion material and made of Q235 carbon structural steel, which has good durability and corrosion resistance. The upper and lower edges of the first guide plate 2 and the second guide plate 3 are welded and fixed to the top plate 6 and the bottom plate 1, respectively, while the front and rear ends are welded and fixed to the sides of the front baffle 4 and the rear baffle 5, respectively.
[0027] Both the front baffle 4 and the rear baffle 5 are rectangular steel plates, located at the front and rear ends of the cavity, respectively. The front baffle 4 has two openings (section 1), with a pipe 7 positioned between them. One end of the pipe 7 passes through the front baffle 4 and connects to the cavity, while the other end extends to the outside. The pipe 7 has a circular cross-section, with its diameter determined based on actual flow requirements. The connection between the pipe 7 and the front baffle 4 is achieved using a sealed welding process to ensure the sealing and strength of the connection. The rear baffle 5 has one opening (section 2) to balance water pressure and assist in drainage. Both openings (section 1 and section 2) contain several grids (sections 8), composed of parallel steel plates arranged at a 45° angle with a 30mm spacing between adjacent plates. The two ends of the grids (sections 8) are welded to the inner walls of openings (section 1 and section 2), forming a back-flow channel to prevent floating debris and aquatic plants from entering the cavity.
[0028] The design of grille 8 is one of the key parts of this utility model. For example... Figure 1 and Figure 2As shown, the tilt angle and spacing of the steel plates in grating 8 are precisely calculated to effectively intercept larger debris while ensuring smooth water flow. The backflow channel design of grating 8 utilizes the movement characteristics of water flow to create localized "dead spots" on the steel plate surface, thereby intercepting floating objects and aquatic plants outside the cavity. Grating 8 is made of stainless steel, which has excellent corrosion resistance.
[0029] The sedimentation inclined plate 10 is installed between the bottom plate 1 and the first guide side plate 2, and between the bottom plate 1 and the second guide side plate 3, in an inclined state, such as Figure 4 As shown. The high end of the sediment settling inclined plate 10 is close to the guide side plate, and the low end is close to the sand discharge port 9 in the middle of the bottom plate 1. The inclination angle of the sediment settling inclined plate 10 is 30°-45°. Its design allows the sediment to slide down the inclined plate to the sand discharge port 9 under the action of gravity, thereby achieving efficient discharge of sediment. The sediment settling inclined plate 10 is fixed to the inner walls of the guide side plate 1 2, the guide side plate 2 3, the front baffle 4, and the rear baffle 5 by welding to ensure that there are no gaps left.
[0030] In the specific embodiments of this utility model, all components are connected by welding or bolting to form a complete structure. The connection method and positional relationship between the components ensure the overall stability and sealing of the water intake head. The design of the water intake head fully considers the actual needs of complex aquatic environments. By optimizing the internal flow channel structure and introducing efficient anti-clogging and sand removal mechanisms, the adaptability and operational efficiency of the water intake head in complex aquatic environments are significantly improved.
[0031] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.
[0032] In practical applications, the entire water intake head is mounted on a support pier to support it and ensure its stability. The support pier should be placed on a flat riverbed rock surface to ensure the overall stability of the water intake head. The water flow direction is towards the guide side plate 2. First, guide side plate 2 and guide side plate 3 guide the water flow, ensuring its even distribution within the cavity and preventing sediment deposition or turbulent flow caused by excessively high or low local flow velocities. When the water enters the cavity, the grating 8 begins to function. Since the grating 8 is composed of parallel steel plates arranged at a 45° angle with a 30mm spacing between adjacent plates, floating debris and aquatic plants are effectively intercepted as the water flows through it. The design of the grating 8 utilizes water flow characteristics, creating localized "dead spots" on the steel plate surface, making it difficult for floating debris to pass through the grating 8 and enter the cavity, thus achieving an anti-clogging function. Simultaneously, the tilt angle and spacing of the grating 8 are precisely calculated to ensure smooth water flow and prevent excessive resistance from affecting the overall water intake efficiency.
[0033] Subsequently, after entering the cavity, the water flows along the gradually narrowing structure of the first guide plate 2 and the second guide plate 3. The cross-sectional shape of the first guide plate 2 and the second guide plate 3 gradually narrows from the side away from the sedimentation inclined plate 10. This design accelerates the water flow within the cavity. The increased water velocity not only reduces the possibility of sediment deposition but also enhances the uniformity of the water flow, avoiding turbulence caused by excessively high or low local flow velocities. During this process, the sediment in the water is deposited onto the sedimentation inclined plate 10 under the influence of gravity. The inclination angle of the sedimentation inclined plate 10 is 30°-45°, with its high end near the guide plate and its low end near the sand discharge port 9 in the middle of the bottom plate 1. The sediment slides down the sedimentation inclined plate 10 to the sand discharge port 9 and is discharged from the cavity through the sand discharge port 9, thus achieving efficient sediment discharge.
[0034] Meanwhile, multiple sand discharge ports 9 on the base plate 1 further assist in the discharge of sediment. These ports 9 are evenly distributed in the central area of the base plate 1. The design of these sand discharge ports 9 fully utilizes gravity, allowing sediment deposited on the base plate 1 to be quickly discharged, preventing sediment accumulation within the cavity. Furthermore, the sediment settling inclined plate 10 is fixed to the inner walls of the first guide side plate 2, the second guide side plate 3, the front baffle 4, and the rear baffle 5 by welding, ensuring no gaps remain and preventing sediment from entering the joints between other components and causing blockages or damage.
[0035] After completing the above processes within the cavity, the water is finally transported to the external system through pipe 7. Pipe 7 has a circular cross-section, with its diameter determined according to actual flow requirements. The connection between pipe 7 and the front baffle 4 employs a sealed welding process to ensure the sealing and strength of the connection. The water flows smoothly out of the cavity through pipe 7, ensuring the continuous operation of the water intake system.
[0036] As can be seen from the above steps, the water intake head provided by this utility model exhibits excellent performance in complex aquatic environments. The backflow channel design of the grid 8 effectively intercepts floating debris, and the inclined structure of the sedimentation plate 10, combined with the sand discharge port 9, enables automatic collection and discharge of sediment. The tapered structure of the first guide plate 2 and the second guide plate 3 optimizes the water flow path, improving the water flow velocity and uniformity. The connection method and positional relationship between the various components ensure the overall stability and sealing of the water intake head, significantly improving its adaptability and operational efficiency in complex aquatic environments.
