Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, specifically a diversion device for water conservancy projects. Background Technology

[0002] In water conservancy engineering systems, diversion and drainage devices occupy an indispensable core position. They not only undertake the crucial task of precisely guiding water from its source to the target area, but also ensure the smoothness and cleanliness of water transmission throughout the entire process. Whether it's the scientific allocation of water in reservoir management, the efficient water supply for farmland irrigation, or the rapid drainage of accumulated water in urban flood control, these devices play an irreplaceable role. Their stable operation directly affects the overall effectiveness of water conservancy projects, while also providing important support for the protection of the surrounding ecological environment and the safety of water for production and daily life.

[0003] In terms of filtration and cleaning maintenance, existing technologies generally filter water by adding a filter screen to the diversion device to remove impurities. However, if the filter screen is not cleaned in time, it can easily become clogged, affecting the efficiency of diversion and requiring frequent cleaning by staff. Therefore, a diversion device for water conservancy projects is proposed here. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a diversion device for water conservancy projects, which has the advantage of automatically cleaning the filter screen of debris, thus solving the problem that the filter screen is affected by debris, resulting in a decrease in water flow efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diversion device for water conservancy projects, including a diversion box and a filter assembly. The filter assembly is disposed inside the diversion box and includes a filter screen. The filter screen is rotatably disposed inside the diversion box and has a turbine installed inside. The device also includes a flushing component disposed inside the diversion box for flushing debris from the filter screen. Finally, the device includes a collection component disposed inside the diversion box for collecting debris.

[0006] Furthermore, the drainage box includes a box body, and an inlet pipe and an outlet pipe are respectively installed at both ends of the box body.

[0007] With the above scheme, the inlet pipe and outlet pipe are fixed to both ends of the box body by stainless steel sealing flanges. The box body, inlet pipe and outlet pipe are all made of stainless steel. The inlet pipe is responsible for introducing the water to be treated, and the outlet pipe is responsible for discharging the filtered clean water, thus constructing a complete diversion channel.

[0008] Furthermore, the filter assembly also includes a mounting base, which is fixed to the inside of the housing, and the filter screen is rotatably connected inside the mounting base.

[0009] With the above solution, the mounting base is fixed to the inside of the box with bolts. The bolts need to be rust-proofed. The mounting base provides a stable rotation support point for the filter screen, ensuring that the filter screen can rotate smoothly during the filtration process.

[0010] Furthermore, the filter assembly also includes a connecting rod and a rotating shaft. The connecting rod is fixed inside the filter screen, the rotating shaft is fixed on the connecting rod, the turbine is fixed on the rotating shaft, and the rotating shaft extends into the water inlet pipe.

[0011] With the above solution, the connecting rod is welded to the frame inside the filter screen, the rotating shaft is welded to the connecting rod, and the turbine is fixed on the rotating shaft. The water flow impacts the turbine, causing the rotating shaft, connecting rod, and filter screen to rotate synchronously, thereby achieving dynamic filtration, enhancing the impurity interception effect, and facilitating the subsequent rinsing of impurities attached to the filter screen.

[0012] Furthermore, the rinsing component includes a submersible pump, which is installed at the bottom of the housing and has a high-pressure nozzle mounted on it, positioned above the filter screen.

[0013] With the above solution, the submersible pump is fixed at the bottom of the tank, and the high-pressure nozzle is connected to the submersible pump through a pipe. The high-pressure nozzle is made of copper. The submersible pump draws filtered water, and the water passes through the high-pressure nozzle to form a high-pressure water flow, which washes away the debris inside the filter screen and prevents the filter screen from becoming clogged.

[0014] Furthermore, the collecting component includes a cylindrical body, in which a collecting cylinder is placed, and a guide plate is fixed on the cylindrical body, the guide plate extending into the filter screen.

[0015] With the above solution, the guide plate is welded to the top of the cylinder, and the collection cylinder is placed inside the cylinder to facilitate the subsequent cleaning of debris inside the collection cylinder. The cylinder, collection cylinder and guide plate are made of stainless steel. The guide plate guides the debris washed down into the collection cylinder, and the collection cylinder collects the debris in a concentrated manner, which is convenient for subsequent cleaning and maintenance.

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

[0017] This diversion device for water conservancy projects allows water to flow into a filter screen through an outlet pipe. During this process, the water flow impacts a turbine, causing the rotating shaft, connecting rod, and filter screen to rotate synchronously. The filtered water is then discharged through the outlet pipe support. The activation of a submersible pump, combined with a high-pressure nozzle, washes the top of the filter screen, causing debris adhering to the inside of the filter screen to fall onto a guide plate. Guided by the guide plate, the water eventually flows into a collection cylinder. This device solves the problem of reduced water flow efficiency caused by debris affecting the filter screen by automatically cleaning debris from the filter screen. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please see Figure 1 , Figure 2 and Figure 3 Please see Figures 1 to 4 The diversion device for water conservancy projects in this embodiment includes a diversion box 1, which includes a box body 101. An inlet pipe 102 and an outlet pipe 103 are respectively installed at both ends of the box body 101. The inlet pipe 102 and the outlet pipe 103 are fixed to both ends of the box body 101 by stainless steel sealing flanges. The box body 101, the inlet pipe 102 and the outlet pipe 103 are all made of stainless steel. The inlet pipe 102 is responsible for introducing the water to be treated, and the outlet pipe 103 discharges the filtered clean water, thus constructing a complete diversion channel.

[0029] It also includes a filter assembly 2, which is disposed in the diversion box 1. The filter assembly 2 includes a filter screen 201, which is rotatably disposed in the diversion box 1. A turbine 202 is installed in the filter screen 201.

[0030] The filter assembly 2 also includes a mounting base 203, which is fixed inside the housing 101. The filter screen 201 is rotatably connected inside the mounting base 203. The mounting base 203 is fixed inside the housing 101 by bolts. The bolts need to be rust-proofed. The mounting base 203 provides a stable rotation support point for the filter screen 201, ensuring that the filter screen 201 can rotate smoothly during the filtration process.

[0031] The filter assembly 2 also includes a connecting rod 204 and a rotating shaft 205. The connecting rod 204 is fixed inside the filter screen 201, the rotating shaft 205 is fixed on the connecting rod 204, the turbine 202 is fixed on the rotating shaft 205, and the rotating shaft 205 extends into the water inlet pipe 102.

[0032] The connecting rod 204 is welded to the frame inside the filter screen 201. The rotating shaft 205 is welded to the connecting rod 204. The turbine 202 is fixed on the rotating shaft 205. The water flow impacts the turbine 202, causing the rotating shaft 205, the connecting rod 204 and the filter screen 201 to rotate synchronously, realizing dynamic filtration, enhancing the impurity interception effect, and facilitating the subsequent rinsing of impurities attached to the filter screen 201.

[0033] It also includes a rinsing component 3, which is installed inside the drainage box 1. The rinsing component 3 is used to rinse the debris on the filter screen 201. The rinsing component 3 includes a submersible pump 301, which is installed at the bottom of the box 101. A high-pressure nozzle 302 is installed on the submersible pump 301 and is located above the filter screen 201.

[0034] The submersible pump 301 is fixed at the bottom of the housing 101. The high-pressure nozzle 302 is connected to the submersible pump 301 through a pipe. The high-pressure nozzle 302 is a copper nozzle. The submersible pump 301 draws filtered water, and the water forms a high-pressure water flow through the high-pressure nozzle 302 to wash away the debris inside the filter screen 201 and prevent the filter holes of the filter screen 201 from becoming clogged.

[0035] It also includes a collection component 4, which is disposed inside the diversion box 1. The collection component 4 is used to collect debris. The collection component 4 includes a cylinder 401, a collection cylinder 402 is placed inside the cylinder 401, and a guide plate 403 is fixed on the cylinder 401. The guide plate 403 extends into the filter screen 201.

[0036] Guide plate 403 is welded to the top of cylinder 401. Collection cylinder 402 is movably placed inside cylinder 401 for easy cleaning of debris. Cylinder 401, collection cylinder 402, and guide plate 403 are all made of stainless steel. Guide plate 403 guides the washed debris into collection cylinder 402, which collects the debris for easy cleaning and maintenance.

[0037] It should be noted that: the sealing flanges connecting the inlet pipe 102 and the outlet pipe 103 need to be checked regularly to prevent leakage; the fixing bolts of the mounting base 203 need to be treated with anti-rust to avoid corrosion affecting the rotation of the filter screen 201; and the connection gap between the filter screen 201 and the mounting base 203 needs to be checked regularly.

[0038] Submersible pump 301 must be installed securely and its operating status should be checked regularly to prevent malfunctions that could prevent rinsing. The nozzle of high-pressure nozzle 302 must be cleaned regularly to avoid clogging and affecting the rinsing effect. Collection cylinder 402 must be removed regularly to clean out debris and prevent it from accumulating and overflowing.

[0039] The welded joints of the guide plate 403 need to be checked for firmness to prevent them from falling off and affecting the guidance of debris. The interior of the box 101 needs to be cleaned regularly to remove sediment and impurities to ensure smooth water flow. All stainless steel components need to be regularly maintained for rust prevention to extend their service life.

[0040] The working principle of the above embodiment is as follows: the water to be treated flows into the filter screen 201 through the water outlet pipe 103. During the above process, the water flow impacts the turbine 202, which drives the rotating shaft 205, the connecting rod 204 and the filter screen 201 to rotate synchronously. The filtered water is discharged through the support of the water outlet pipe 103.

[0041] The submersible pump 301 is started periodically. The start of the submersible pump 301, together with the high-pressure nozzle 302, can wash the top of the filter screen 201, so that the debris attached to the inside of the filter screen 201 falls onto the guide plate 403 and finally flows into the collection cylinder 402 under the guidance of the guide plate 403. This device has the advantage of automatically cleaning the debris from the filter screen 201, thus solving the problem of reduced water flow efficiency caused by debris affecting the filter screen.
