Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water conservancy engineering trash rack that is easy to clean. Background Technology

[0002] According to the patent document with publication number CN220117149U, the patent document describes a method to intercept debris in water flow using several first vertical bars in a fixed grid. A movable grid with several hooks at the bottom is set on one side of the fixed grid. The movable grid is automatically lifted by a motor, winch, and rope. During the lifting process, the hooks of the movable grid hook the blocked debris upwards from the water surface within the gaps of the fixed grid, making it easier for the operator to retrieve them. By making the top surface of the slide groove in the slide rail and the outside of the slide rail through it, the movable grid can slide out of the slide rail as a whole by a slider, which facilitates the cleaning of the movable grid later.

[0003] The patent document describes a fixed grid system for intercepting debris in water flow. However, because the spacing between the first vertical bars of the fixed grid is fixed and cannot be adjusted according to weather and water flow conditions, this results in a contradiction between debris interception and drainage effectiveness. In cases of heavy rain or flood control, when rapid drainage is required, the fixed grid may obstruct drainage if it intercepts debris according to normal needs. Furthermore, the first vertical bars are submerged for extended periods, and their surfaces can accumulate mud or algae. If not cleaned promptly, the gaps between the first vertical bars will narrow, affecting the drainage effect. Utility Model Content

[0004] The purpose of this invention is to provide a water conservancy project debris barrier that is easy to clean in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A water conservancy project trash rack that is easy to clean includes two fixing frames, as well as an adjustment mechanism and a cleaning mechanism;

[0007] The distance adjustment mechanism includes a distance adjustment plate for adjusting the distance between the debris-blocking bars. The distance adjustment plate is slidably connected to the top of two fixed frames. Several sliding rods are slidably connected to the front side of the distance adjustment plate. The bottom of each sliding rod is fixedly connected to a first debris-blocking bar. Second debris-blocking bars are provided on both sides of each first debris-blocking bar. A first support rod is fixed to the front side of the two fixed frames. The tops of the first debris-blocking bars and the two second debris-blocking bars are all fitted onto the outside of the first support rod.

[0008] The cleaning mechanism includes a second support rod located below the first support rod. A first scraper is fitted at the bottom of the first baffle rod, and a second scraper is fitted at the bottom of the second baffle rod. Both the first and second scrapers are slidably connected to the rear side of the second support rod. A collection plate is fixed at the bottom of the second support rod.

[0009] Preferably, each of the two fixing frames has several insert rods fixed at its bottom, and each of the two fixing frames has a first sliding groove on the side near the adjusting plate.

[0010] Preferred configuration: cylinders are fixedly installed on both sides of the top of the adjusting plate, sliding seats are fixed on both sides of the second support rod, lead screws are rotatably connected to both sides of the two fixed frames, the sliding seats are threaded to the outside of the lead screws, and a motor is fixedly installed at the input end of the lead screws.

[0011] Preferably, a T-shaped slider is fixed to the front side of both the first scraper and the second scraper, a second groove that cooperates with the T-shaped slider is opened on the front side of the second support rod, and a water passage hole is opened on the collection plate to allow water in the debris to flow out.

[0012] Preferably, a circular slider is fixed to the rear side of the top of the slider, and a straight groove that cooperates with the circular slider is opened on the adjustment plate. Several straight grooves are symmetrically divided into two groups along the center line of the adjustment plate.

[0013] Preferably, both the first and second debris-blocking bars have sliding holes at their tops for sliding connection with the first support bar.

[0014] The advantages compared to existing technologies are as follows:

[0015] 1. Two cylinders drive the adjusting plate to rise and fall on the top of the two fixed frames. The rising and falling of the adjusting plate causes the slide bar to slide along both sides. The slide bar then causes the first debris barrier to slide outside the first support rod, thereby adjusting the distance between several first debris barriers to facilitate the adjustment of drainage effect according to different situations.

[0016] 2. The first and second scrapers are slid behind the second support rod by the debris-blocking rod. The sliding seat drives the second support rod and the collection plate to move. In turn, the second support rod drives the first and second scrapers to move to scrape away debris from the surface of the first and second debris-blocking rods, so as to avoid the accumulation of debris on the surface of the debris-blocking rods and improve the drainage effect.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8 As shown, a water conservancy project trash rack that is easy to clean includes two fixed frames 1, as well as an adjustable distance mechanism 3 and a cleaning mechanism 4.

[0031] In this embodiment: the adjusting mechanism 3 includes an adjusting plate 301 for adjusting the distance between the debris-blocking bars. The adjusting plate 301 is slidably connected to the top of two fixed frames 1. Several insert rods 2 are fixed to the bottom of each of the two fixed frames 1. A first sliding groove is opened on the side of each of the two fixed frames 1 near the adjusting plate 301. Cylinders 306 are fixedly installed on both sides of the top of the adjusting plate 301. Several slide rods 302 are slidably connected to the front side of the adjusting plate 301. A circular slider is fixed to the rear side of the top of the slide rods 302. A straight groove that cooperates with the circular slider is opened on the adjusting plate 301. Several straight grooves are symmetrically divided into two groups around the center line of the adjusting plate 301. Several slide rods 302 are slidably connected to the front side of the adjusting plate 301. 2. Each of the two fixed frames 1 has a first baffle bar 303 fixedly connected to its bottom. Each of the first baffle bars 303 has a second baffle bar 304 on both sides. Each of the two fixed frames 1 has a first support rod 305 fixed to its front side. The tops of the first baffle bars 303 and the two second baffle bars 304 are fitted over the outside of the first support rod 305. The two cylinders 306 drive the adjusting plate 301 to rise and fall on the top of the two fixed frames 1. The rising and falling of the adjusting plate 301 drives the sliding rod 302 to slide along both sides. The sliding of the sliding rod 302 drives the first baffle bars 303 to slide outside the first support rod 305, thereby adjusting the distance between the first baffle bars 303.

[0032] In this embodiment: the cleaning mechanism 4 includes a second support rod 401, which is located below the first support rod 305. A first scraper 403 is fitted onto the bottom of the first baffle rod 303, and a second scraper 404 is fitted onto the bottom of the second baffle rod 304. Both the first and second scrapers 403 and 404 are slidably connected to the rear side of the second support rod 401. T-shaped sliders are fixed to the front sides of both the first and second scrapers 403 and 404. A second groove cooperating with the T-shaped slider is provided on the front side of the second support rod 401. A collection plate 402 is fixed to the bottom of the second support rod 401, and a water passage hole is provided on the collection plate 402 to allow water to flow out from the debris. Sliding seats 405 are fixed to both sides of the second support rod 401. Both fixed brackets 1 are rotated on both sides. A lead screw 406 is dynamically connected, and a sliding seat 405 is threaded to the outside of the lead screw 406. A motor 407 is fixedly installed at the input end of the lead screw 406. The first and second debris-blocking rods 303 and 304 respectively drive the first scraper 403 and the second scraper 404 to slide behind the second support rod 401. The motor 407 drives the lead screw 406 to move the sliding seat 405. The sliding seat 405 drives the second support rod 401 and the collection plate 402 to move. In turn, the second support rod 401 drives the first scraper 403 and the second scraper 404 to move to scrape away debris from the surfaces of the first and second debris-blocking rods 303 and 304. The collection plate 402 pushes the debris intercepted by the first and second debris-blocking rods 303 and 304 out of the water.

[0033] Working principle: The device is fixed by inserting the rods 2 at the bottom of the two fixed frames 1 into the water. When rapid drainage is needed during heavy rain or flood control, the two cylinders 306 push the adjusting plate 301 down along the first slide groove at the top of the two fixed frames 1. During the descent of the adjusting plate 301, the two sets of circular sliders slide to both sides in the straight groove. The sliders drive the corresponding slide rods 302 to slide to both sides. The slide rods 302 drive the first debris-blocking rods 303 to slide to both sides in two sets on the outside of the first support rod 305, thereby increasing the distance between several first debris-blocking rods 303. The first debris-blocking rods 303 on both sides contact and push the corresponding second debris-blocking rods 304 to move. The first debris-blocking rods 303 and the second debris-blocking rods 304 drive the first scraper 403 and the second scraper 404 to move respectively. The front sides of the first scraper 403 and the second scraper 404... The T-shaped slider slides in the second groove behind the second support rod 401. When it is necessary to retrieve the intercepted debris, the two motors 407 drive the two lead screws 406 to move the two sliding seats 405 upward. The two sliding seats 405 drive the second support rod 401 and the collection plate 402 upward. Then, the second support rod 401 drives the first scraper 403 and the second scraper 404 to move upward to scrape the debris from the surfaces of the first and second debris barriers 303 and 304. The collection plate 402 pushes the debris intercepted by the first and second debris barriers 303 and 304 out of the water. After the staff retrieves the debris from the collection plate 402, the two motors 407 drive the second support rod 401 and the collection plate 402 to move downward and reset. The second support rod 401 drives the first scraper 403 and the second scraper 404 to move downward and reset.
