Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy, in particular to a flow guiding device. Background Art

[0002] In the process of water conservancy construction, in order to facilitate the diversion of water flow, it is necessary to build canals to guide the water flow, so as to achieve the effect of diversion. Canals are artificially excavated waterways, which are divided into main canals and branch canals. Main canals and branch canals are generally built with stone or cement;

[0003] In the process of diverting water in existing water conservancy canals, weeds and various large impurities are present in the water flowing in the canals, so that the impurities are easily silted up in the canals. Long-term siltation is easy to cause canals to be blocked, thus affecting the fluidity of the water flow in the canals. Therefore, we propose a diversion device. Utility Model Content

[0004] The purpose of the utility model is to provide a flow guiding device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a diversion device, comprising a water channel, a rotating shaft is rotatably installed on the inner wall of the water channel, a plurality of evenly distributed mesh plates adapted to the inner cavity of the water channel are fixed on the outer wall of the rotating shaft, a servo motor is fixed on one side wall of the water channel corresponding to the rotating shaft, a transmission shaft of the servo motor passes through the side wall of the water channel and is fixedly connected to the end of the rotating shaft, a support plate is fixed to one side of the top of the water channel, an electric push rod is fixed to the outer wall of the support plate, and the push rod of the electric push rod movably passes through the support plate and is fixedly connected to a scraper.

[0006] By adopting the above technical scheme, the mesh plate located on the lower side of the rotating shaft can be perpendicular to the bottom of the inner cavity of the water channel, so that the weeds and impurities in the water flowing in the water channel can be blocked. When more weeds and impurities are intercepted, starting the servo motor can drive the rotating shaft to rotate step by step, and rotate a certain distance, so that the next mesh plate is perpendicular to the bottom of the inner cavity of the water channel. After the rotation, the electric push rod can drive the scraper to move, so that the scraper can push the impurities and weeds intercepted between two adjacent mesh plates to the outside of the water channel, thereby realizing the cleaning function; therefore, as the garbage is intercepted, the mesh plate is gradually rotated, and can be cleaned one by one, so that the weeds and impurities can be cleaned continuously and uninterruptedly.

[0007] As a preferred embodiment of the utility model, a liquid level switch is fixed on the upper side of one side wall of the inner cavity of the water channel.

[0008] By adopting the above technical solution, the liquid level switch, the servo motor and the electric push rod are electrically connected, so that when the impurities and weeds intercepted by the mesh plate located on the lower side are large, it will affect the permeability of the water flow, so that the water level in the water channel will rise, and the liquid level switch will automatically start the servo motor and the electric push rod after detecting that the water level has risen to a certain height, thereby realizing automatic replacement of the mesh plate and automatic driving of the scraper to clean the impurities and weeds.

[0009] As a preferred embodiment of the utility model, an arc-shaped plate adapted to the rotating shaft is fixed to one end of the mesh plate close to the rotating shaft, and the arc-shaped plate is fitted to the outer wall of the rotating shaft and fixed by bolts.

[0010] By adopting the above technical solution, the screen plate can be easily disassembled and assembled, and can be easily replaced after being damaged, thereby improving the convenience of the replacement operation.

[0011] As a preferred embodiment of the utility model, limiting rods are fixed on both sides of one side wall of the scraper, and the limiting rods movably penetrate the support plate.

[0012] By adopting the above technical solution and setting the limit rod, the movement stability of the scraper is high.

[0013] As a preferred embodiment of the present invention, two side walls of the scraper are attached to two corresponding adjacent side walls of the mesh plate.

[0014] By adopting the above technical solution, it is ensured that the scraping effect can be ensured when pushing the impurities between the screen plates.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] A diversion device of the technical solution of the present application is provided with a rotating shaft in a water channel, and a plurality of mesh plates are fixed on the rotating shaft, and one of the mesh plates is used to be perpendicular to the bottom of the inner cavity of the water channel, so that weeds and other impurities in the water channel can be intercepted. When there are many weeds blocked by the mesh plates, the servo motor is started to drive the rotating shaft to rotate, so that the mesh plates with weeds are rotated upward, and the intercepted weeds can be pushed out by driving the scraper with an electric push rod, so as to achieve the effect of cleaning the weeds and impurities, and avoid the situation that the weeds and impurities are accumulated in the water channel and cause blockage;

[0017] When weeds and impurities accumulate on the lower mesh plate, the water flow will be blocked, causing the water level to rise. When the liquid level switch detects that the water level has risen to a certain position, it will automatically start the servo motor and the electric push rod to work, thereby realizing automatic adjustment of the mesh plate and automatically starting the electric push rod to drive the scraper to clean the intercepted weeds.

[0026] In actual use, the mesh plate 13 located at the lower side of the rotating shaft 12 can be perpendicular to the bottom of the inner cavity of the water channel 1, so that the weeds and impurities in the water flowing in the water channel 1 can be blocked. When a large number of weeds and impurities are intercepted, the servo motor 11 is started to drive the rotating shaft 12 to rotate step by step, and rotate a certain distance, so that the next mesh plate 13 is perpendicular to the bottom of the inner cavity of the water channel 1. After the rotation, the electric push rod 22 can drive the scraper 21 to move, so that the scraper 21 can push the impurities and weeds intercepted between two adjacent mesh plates 13 to the outside of the water channel 1, thereby realizing the cleaning function; as the garbage is intercepted, the mesh plate 13 is gradually rotated, and can be cleaned one by one, so that the weeds and impurities can be cleaned continuously and uninterruptedly;

[0027] Furthermore, the two side walls of the scraper 21 are attached to the corresponding two adjacent side walls of the mesh plates 13, thereby ensuring the scraping effect when pushing the impurities between the mesh plates 13;

[0028] Furthermore, both sides of one side wall of the scraper 21 are fixed with limit rods 23, and the limit rods 23 are movable through the support plate 2. The setting of the limit rods 23 makes the movement stability of the scraper 21 high;

[0029] It is worth mentioning that an arc-shaped plate 14 adapted to the rotating shaft 12 is fixed to one end of the mesh plate 13 close to the rotating shaft 12. The arc-shaped plate 14 is attached to the outer wall of the rotating shaft 12 and fixed by bolts, so that the mesh plate 13 is easy to disassemble and assemble, and is convenient for replacement after damage, thereby improving the convenience of the replacement operation;

[0030] like Figure 1 and 2 As shown; a liquid level switch 15 is fixed on the upper side of one side wall of the inner cavity of the water channel 1, and the liquid level switch 15 is electrically connected to the servo motor 11 and the electric push rod 22, so that when the impurities and weeds intercepted by the mesh plate 13 at the lower side are large, it will affect the permeability of the water flow, so that the water level in the water channel 1 will rise, and the liquid level switch 15 will automatically start the servo motor 11 and the electric push rod 22 after detecting that the water level rises to a certain height, thereby realizing automatic replacement of the mesh plate 13 and automatic driving of the scraper 21 to clean the impurities and weeds.

[0031] The implementation principle of a diversion device of the present application is as follows: in actual use, the mesh plate 13 located on the lower side of the rotating shaft 12 can be perpendicular to the bottom of the inner cavity of the water channel 1, so that the weeds and impurities in the water flowing in the water channel 1 can be blocked. When more weeds and impurities are intercepted, the water level in the water channel 1 will rise, so that the liquid level switch 15 will automatically start the servo motor 11 and the electric push rod 22 after detecting that the water level has risen to a certain height, thereby realizing automatic start-up. The servo motor 11 can drive the rotating shaft 12 to rotate step by step, and rotate a certain distance, so that the next mesh plate 13 is perpendicular to the bottom of the inner cavity of the water channel 1. After the rotation, the electric push rod 22 can drive the scraper 21 to move, so that the scraper 21 can push the impurities and weeds intercepted between two adjacent mesh plates 13 to the outside of the water channel 1, thereby realizing the cleaning function; as the garbage is intercepted, the mesh plate 13 is gradually rotated, and can be cleaned one by one, so that continuous and uninterrupted cleaning of weeds and impurities can be achieved.
