Description

Technical Field

[0001] This utility model relates to the field of overflow weir technology, and in particular to an adjustable overflow weir structure for intercepting wells. Background Technology

[0002] Interception wells play a crucial role in modern urban drainage systems and sewage treatment projects. The core function of interception wells is to effectively control the combined flow of sewage and rainwater under different hydrological conditions and operating conditions, ensuring that sewage can be properly collected and transported to sewage treatment plants. However, under different seasons, rainfall intensities, and sewage flow rates, during the dry season when sewage flow is low and water quality is relatively poor, the interception well cannot increase the interception flow by lowering the overflow weir height. This results in some sewage potentially being lost through the overflow weir and not being effectively collected and treated, thus affecting the treatment efficiency and water quality compliance of the sewage treatment plant. During the rainy season, the water inflow increases dramatically. If the overflow weir height cannot be raised in time, excessive rainwater will flow into the interception pipe, increasing the operational burden of the sewage treatment plant and potentially causing operational failures and environmental risks. Therefore, this utility model provides an adjustable overflow weir structure for intercepting wells. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable overflow weir structure for intercepting wells.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable overflow weir structure for a diversion well, including an overflow weir frame and an adjustment component. The adjustment component includes a chute formed inside the overflow weir frame, a sliding plate slidably connected to the chute, a connecting ring fixedly connected to the outside of the sliding plate, and a connecting rope fixedly connected to the outside of the connecting ring. The power assembly includes a slide rail fixedly connected to the outside of the overflow weir frame, a first slider slidably connected to the outside of the slide rail, a connecting frame fixedly connected inside the first slider, and a counterweight fixedly connected to the outside of the connecting frame.

[0005] In a preferred embodiment, a pulley is installed on the outer side of the overflow weir frame, and the outer side of the connecting rope is sleeved on the pulley.

[0006] In a preferred embodiment, an extension rod is fixedly connected to the top of the counterweight, and the end of the connecting rope away from the connecting ring is fixedly connected to the top of the extension rod.

[0007] In a preferred embodiment, a second slider is slidably connected to the outer side of the slide rail, and a crossbar is fixedly connected to the inside of the second slider.

[0008] In a preferred embodiment, the crossbar is internally fixedly connected to the extension bar.

[0009] In a preferred embodiment, the counterweight is internally slidably connected to the outside of the overflow weir frame.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. The counterweight provides a constant downward pulling force due to its own weight, which in turn drives the first slider to move down along the slide rail. The extension rod drives the crossbar and the second slider to move down along the slide rail synchronously. This design utilizes gravity as a power source without external energy, ensuring that the extension rod and counterweight can only move smoothly along a predetermined vertical path, providing the basic power for automatic or semi-automatic adjustment of the overflow weir height. 2. The extension rod drives the connecting rope downwards. The connecting rope changes direction after passing through the pulley, and the rope after the pulley changes direction pulls the connecting ring. Then the connecting ring drives the slide plate to slide upwards along the chute. This design converts the downward gravity of the counterweight into an upward lifting force on the slide plate through the pulley. This allows even a smaller sewage flow to enter the interception pipe earlier and in greater quantities through the area below the weir plate. This increases the sewage interception rate during the dry season and effectively solves the problem of sewage loss caused by the inability to lower the weir height during the dry season.

[0013] 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.

[0014] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: an adjustable overflow weir structure for a diversion well, including an overflow weir frame 1 and an adjustment component 2. The adjustment component 2 includes a chute 21 opened inside the overflow weir frame 1, a slide plate 22 slidably connected to the chute 21, a connecting ring 23 fixedly connected to the outside of the slide plate 22, a connecting rope 24 fixedly connected to the outside of the connecting ring 23, a pulley 25 installed on the outside of the overflow weir frame 1, and the outside of the connecting rope 24 sleeved on the pulley 25. The overflow weir frame 1, as the main frame of the entire overflow weir structure, serves to bear and support other components, providing a stable installation foundation for the regulating component 2 and the power component 3. This ensures the stability of the entire structure under conditions such as water flow impact. The chute 21 provides a sliding track for the slide plate 22, restricting the movement direction of the slide plate 22 and allowing it to slide up and down along a predetermined path inside the overflow weir frame 1. The slide plate 22 changes the effective height of the overflow weir by sliding within the chute 21, thereby regulating the overflow flow rate. When the slide plate 22 slides upward, the height of the overflow weir decreases, allowing more water to pass through; when the slide plate 22 slides downward, the height of the overflow weir increases, reducing the overflow flow rate. The connecting ring 23 serves as the connecting component between the slide plate 22 and the connecting rope 24, transmitting the movement of the slide plate 22 and the traction force of the connecting rope 24. It can effectively transmit the tension of the connecting rope 24 to the slide plate 22, and at the same time, it can also transmit the reaction force such as the water pressure on the slide plate 22 to the connecting rope 24. The connecting rope 24 connects the power component 3 and the adjustment component 2, and as a force transmission medium, the movement of the power component 3 is converted into the sliding of the slide plate 22 in the adjustment component 2 through the traction of the connecting rope 24. The pulley 25 changes the movement direction of the connecting rope 24, so that the connecting rope 24 can be led out from the inside of the overflow weir frame 1 to the outside, and reduces the frictional resistance of the connecting rope 24 during the movement. like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the power assembly 3 includes a slide rail 31 fixedly connected to the outside of the overflow weir frame 1. A first slider 32 is slidably connected to the outside of the slide rail 31. A connecting frame 33 is fixedly connected inside the first slider 32. A counterweight 34 is fixedly connected to the outside of the connecting frame 33. An extension rod 35 is fixedly connected to the top of the counterweight 34. One end of the connecting rope 24 away from the connecting ring 23 is fixedly connected to the top of the extension rod 35. A second slider 36 is slidably connected to the outside of the slide rail 31. A crossbar 37 is fixedly connected inside the second slider 36. The inside of the crossbar 37 is fixedly connected to the extension rod 35. The inside of the counterweight 34 is slidably connected to the outside of the overflow weir frame 1. The slide rail 31 provides a sliding track for the first slider 32 and the second slider 36, guiding them to slide along a predetermined path and bearing the force transmitted from the sliders. The first slider 32 slides on the slide rail 31 and is connected to components such as the connecting frame 33. As a support and sliding component for the counterweight 34 and its connected extension rod 35, it can transmit the weight of the counterweight 34 to the slide rail 31 and achieve force transmission and adjustment through its own sliding. The connecting frame 33 connects the first slider 32 and the counterweight 34, allowing the counterweight 34 to slide on the slide rail 31 along with the first slider 32, and effectively transmits the weight of the counterweight 34 to the first slider 32. The counterweight 34 generates tension or pressure through its own weight, providing power to the adjusting component 2. When the weight of the counterweight 34 passes through the connecting frame 33 and the first slider 36, the first slider 32... When the slider 32, extension rod 35, and connecting rope 24 are transmitted to the slide plate 22, the slide plate 22 can slide according to the set force, thereby adjusting the height of the overflow weir. The extension rod 35 connects the counterweight 34 to the connecting rope 24, and transmits the weight of the counterweight 34 to the connecting rope 24 through the extension rod 35, thereby realizing the control of the force of the adjusting component 2. The second slider 36 slides on the slide rail 31 and is connected to the crossbar 37 and the extension rod 35, which plays the role of guiding and supporting the extension rod 35, and at the same time can limit the movement direction of the extension rod 35, so that it slides stably along the direction of the slide rail 31. The crossbar 37 connects the second slider 36 and the extension rod 35, so that the second slider 36 can drive the extension rod 35 to slide together on the slide rail 31, and can withstand a certain amount of tension and pressure to ensure the transmission of force.

[0015] Working principle: like Figure 1 - Figure 5 As shown: In use: First, the counterweight 34 generates a downward force due to its own weight. This then drives the connecting frame 33 and extension rod 35, which are fixedly connected to it, to move downwards together. Next, the first slider 32, fixedly connected to the connecting frame 33, slides downwards along the slide rail 31. Simultaneously, the crossbar 37, fixedly connected to the extension rod 35, moves downwards. Next, the second slider 36, fixedly connected to the crossbar 37, slides downwards along the slide rail 31. This then drives the connecting rope 24, fixed to the top of the extension rod 35, to move downwards. As the connecting rope 24 moves downwards, it changes direction via the pulley 25, thereby pulling the connecting ring 23 fixed to the other end of the connecting rope 24. This then drives the sliding plate 22, fixedly connected to the connecting ring 23, to slide upwards along the chute 21. This reduces the effective height of the overflow weir, achieving the effect of increasing the water overflow rate.

[0016] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the form of the present utility model. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in their field. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
