[0019] The utility model is further described below by specific embodiments in combination with the drawings, but is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.

[0020] EMBODIMENT

[0021] The water conservancy gate for water conservancy engineering design disclosed by the embodiment comprises a support frame 1, a limiting groove, a gate, a screen 3 and a cleaning assembly, all of which are structures of the prior art. Figure 1 And Figure 2 As shown in the drawings, the utility model discloses a water conservancy gate for water conservancy engineering design, comprising a support frame, a limiting groove, a gate, a screen and a cleaning assembly, and the patent number thereof is CN202420154716.6, and the cleaning assembly of the application is improved to solve the existing problems.

[0022] The cleaning assembly comprises a scraper 2, which comprises a horizontally arranged fixed plate 2.3, the fixed plate 2.3 is obliquely arranged with a connecting plate 2.4 near one end of the screen 3, the connecting plate 2.4 is in sliding fit with the support frame 1 in up and down direction, and the connecting plate 2.4 is obliquely arranged with low inside and high outside, the movable end of the connecting plate 2.4 is closely combined with the screen 3, and the connecting plate 2.4 is provided with a left and right through groove, and the collecting net 2.2 is installed in the groove;

[0023] The outer side of the top end of the support frame 1 is provided with a driving assembly for driving the fixed plate 2.3 to lift, so as to drive the connecting plate 2.4 to lift, so that the connecting plate 2.4 moves up and down on the screen 3 to scrape off the floating objects attached to the surface and near the screen 3, so as to avoid the accumulation of floating objects affecting the water flow;

[0024] The inner side wall of the support frame 1 is vertically provided with a sliding groove, and the sliding groove is provided with a sliding block in sliding fit with the sliding groove in up and down direction, and the sliding block is fixed with the side wall of the connecting plate 2.4;

[0025] The fixed plate 2.3 is heavy, which is convenient for insertion into water and improves the stability during lifting. In actual use, weight blocks can be added on the fixed plate 2.3 according to the water flow to improve the water entry speed and stability.

[0026] The connecting plate 2.4 and the screen 3 are provided with an adjusting plate 2.1, and the adjusting plate 2.1 is made of elastic material. In natural state, the adjusting plate 2.1 is closely combined with the screen 3, which is convenient for cleaning the floating objects attached to the screen 3, reducing the wear of the screen 3, prolonging the service life of the screen 3, and maintaining the filtering effect of the floating objects in water, avoiding the change of the gap of the screen 3 caused by hard friction between the connecting plate 2.4 and the screen 3, causing blockage and too much garbage discharge.

[0027] As shown in Figure 3 The adjusting plate 2.1 and the connecting plate 2.4 are hinged to swing up and down, and in natural state, the adjusting plate 2.1 and the connecting plate 2.4 are perpendicular, which is convenient for increasing the adhesion of the adjusting plate 2.1 and the screen 3, and when the adjusting plate 2.1 and the screen 3 are separated, the floating objects scraped off by the adjusting plate 2.1 are collected into the collecting net 2.2 under the driving of the adjusting plate 2.1;

[0028] The hinge between the adjusting plate 2.1 and the connecting plate 2.4 is achieved by a torsion spring, so that the adjusting plate 2.1 and the screen 3 are disengaged from the state of being attached, and the adjusting plate 2.1 is reset to be perpendicular to the connecting plate 2.4. The hinge can also be achieved by a tension spring between the fixed plate 2.3 and the adjusting plate 2.1. When the hinge is achieved by a tension spring, a limiting block is arranged on the outer side of the fixed plate 2.3 to limit the maximum swing amplitude of the adjusting plate 2.1. The limiting block is used to limit the included angle between the inner side wall of the adjusting plate 2.1 and the inner side wall of the connecting plate 2.4 to be less than 180 degrees, so as to avoid the adjusting plate 2.1 being swung downward too much and being pulled in the opposite direction by the tension spring.

[0029] The connecting plate 2.4 and the fixed plate 2.3 are both hollow structures, which can reduce the resistance in water and reduce energy consumption, thereby reducing the cost.

[0030] The top of the screen 3 is provided with a guide plate 10, which is an arc structure as a whole. The distance from the movable end of the guide plate 10 to the screen 3 is equal to or less than the distance between the bottom end of the connecting plate 2.4 and the screen 3, so as to avoid collision between the connecting plate 2.4 and the guide plate 10 when the connecting plate 2.4 is lifted.

[0031] The driving assembly includes a double-shaft motor 7, which is fixed to the front side wall of the top end of the support frame 1 through a second fixed block 8. The double-shaft motor 7 is connected with wire rollers 6 at both ends. The wire rollers 6 are connected with the support frame 1 through a first fixed block 5. The wire rollers 6 are both wound with connecting ropes 4. The movable end of the connecting rope 4 is detachably connected with the fixed plate 2.3. The double-shaft motor 7 drives the two wire rollers 6 to rotate simultaneously, so that the connecting plate 2.4 is lifted more stably, thereby facilitating the adjusting plate 2.1 to scrape off the floating objects on the screen 3, and improving the scraping effect.

[0032] The first fixed block 5 is located at both ends of the wire roller 6, and the wire roller 6 is connected with the first fixed block 5 through a bearing, so as to stably control the stretching and contraction of the connecting rope 4 through the front and rear rotation of the wire roller 6 driven by the double-shaft motor 7.

[0033] The double-shaft motor 7 can also be replaced by two motors. Because of the characteristics of the wire roller 6 and the connecting rope 4, even if the two motors cannot be completely synchronized, it does not affect the use.

[0034] Two connecting rings 9 are symmetrically arranged on the top of the fixed plate 2.3, and the connecting rings 9 are located outside the connecting ropes 4. When the collecting net 2.2 is full, the double-shaft motor 7 and the wire roller 6 are used to lift the collecting net 2.2, and then the hook is connected with the connecting ring 9 to pull the collecting net 2.2 to the support frame 1 as a whole, so as to clean the garbage in the collecting net 2.2, and avoid that too many floating objects in the water affect the water flow at the screen 3.

[0035] The working principle is that the double-shaft motor 7 is started to drive the wire roller 6 to rotate and wind the connecting rope 4, the wire roller 6 drives the fixed plate 2.3 to rise upward when the connecting rope 4 is retracted, the movement track of the fixed plate 2.3 is limited by the sliding block during the lifting process, so that the adjusting plate 2.1 is always closely attached to the screen 3; the fixed plate 2.3 is continuously lifted when the garbage in the collecting screen 2.2 is cleaned, when the adjusting plate 2.1 is attached to the guide plate 10, the garbage on the adjusting plate 2.1 and the fixed plate 2.3 is guided into the collecting screen 2.2 under the action of the guide plate 10, the adjusting plate 2.1 swings upward and resets to be perpendicular to the connecting plate 2.4 at the moment when the adjusting plate 2.1 is separated from the guide plate 10, so as to push the garbage scraped by the adjusting plate 2.1 into the inside or the back side.
