Description

Technical Field

[0001] The utility model belongs to the technical field of drainage channel structures, and specifically relates to a high-standard farmland drainage channel of a water conservancy project. Background Art

[0002] Farmland irrigation often uses water from rivers, which is introduced into farmland through "ditches" dug on the ground. Canals are artificially dug waterways, which are divided into main canals and branch canals. Main canals and branch canals are generally built with stone or cement. With the rapid development of agriculture, various water conservancy projects and facilities are also rapidly built. Among them, canals are a very important one, which has greatly promoted the development of agriculture.

[0003] The existing patent application number is CN202220950090.0, which is a farmland irrigation and drainage channel, including a channel body, a channel groove, a filter plate for intercepting debris, a fixed groove formed in the inner wall of the channel groove, the filter plate is plugged into the fixed groove, and a traction structure for removing the filter plate from the fixed groove is provided on the filter plate. The application has the effect of facilitating the cleaning of debris remaining in the filter holes of the filter plate in the channel.

[0004] The above patent allows the filter plate to be moved up and down for disassembly and installation, and then the impurities on the filter plate can be cleaned. However, when some impurities flow with the water and are blocked by the filter, these impurities will settle downwards and will not necessarily be adsorbed on the filter plate. As time goes by, these precipitated impurities will accumulate more and more. Even if the filter plate is taken out and cleaned, these precipitated impurities will not be affected. At the same time, as the sediment accumulates more and more, it will eventually cause the drain to be blocked.

[0005] Therefore, it is necessary to improve the deficiencies and defects of the prior art and provide a high-standard farmland drainage channel for water conservancy projects. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a high-standard farmland drainage channel of a water conservancy project that can overcome the above problems or at least partially solve the above problems.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a high-standard farmland drainage channel of a water conservancy project, comprising a canal body with an inverted trapezoidal channel, support blocks are fixedly installed on both sides of the inner wall of the canal body, and a blocking plate is fixedly installed on the support block. The support block is provided with a fixed slide groove, and a filter plate is slidably installed on the fixed slide groove. The shape of the filter plate matches the inverted trapezoidal channel, and a collecting frame is fixedly installed on the bottom front end of the filter plate. The direction of the bottom front end of the filter plate is opposite to the flow direction of the water flow, and the bottom surface of the canal body is provided with a collecting groove matching the collecting frame.

[0008] In order to prevent the settled garbage from accumulating in front of the collecting frame, preferably, the top surface of the collecting frame is lower than the channel bottom surface of the channel body.

[0009] In order to facilitate the extraction of the filter plate, preferably, a handle is fixedly mounted on the top of the filter plate.

[0010] In order to limit the position of the blocking plate, preferably, a plurality of the fixed sliding grooves are evenly arranged on the support block, and a fixed block matching the fixed sliding groove is fixedly mounted on the bottom surface of the blocking plate.

[0011] In order to make the baffle plate and the water channel body fit closely, further, both sides of the baffle plate are inclined surfaces, and the inclination angle matches the inclined surface of the channel.

[0012] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model is a high-standard farmland drainage channel of a water conservancy project, which is blocked from the top of the channel body by a baffle plate to prevent impurities such as dead branches and leaves from falling into the water flow in the channel body, thereby reducing the generation of precipitated and corrupted substances; the filter plate then blocks the debris flowing down from the upstream of the water flow to prevent it from flowing into the farmland, and the blocked debris falls into the collection frame. It only needs to pull out the filter plate and clean the collection frame. The operation steps are simple, which can avoid the blockage of the channel body caused by the accumulation of precipitated and corrupted substances, thereby improving the utilization efficiency of the channel body.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Example:

[0023] Reference Figure 1-5 As shown, a high-standard farmland drainage channel of a water conservancy project includes a water channel body 1 with an inverted trapezoidal channel, support blocks 4 are fixedly installed on both sides of the inner wall of the water channel body 1, and a blocking plate 2 is fixedly installed on the support block 4. A fixed slide 401 is provided on the support block 4, and a filter plate 3 is slidably installed on the fixed slide 401. The shape of the filter plate 3 matches the inverted trapezoidal channel, and a collecting frame 5 is fixedly installed at the bottom front end of the filter plate 3. The direction of the bottom front end of the filter plate 3 is opposite to the flow direction of the water flow, and the bottom surface of the water channel body 1 is provided with a collecting groove 101 matching the collecting frame 5.

[0024] The top surface of the collecting frame 5 is lower than the bottom surface of the channel body 1. If the top surface of the collecting frame 5 is higher than the bottom surface of the channel body 1, some sediments will flow downward along the bottom surface of the channel with the water flow, and after being blocked by the collecting frame 5, they will accumulate in front of the collecting frame 5, making it impossible to collect the sediments.

[0025] A handle 301 is fixedly mounted on the top of the filter plate 3 . By holding the handle 301 , it is convenient to extract or put down the filter plate 3 , thereby improving the efficiency of installing and removing the filter plate 3 .

Both sides of the baffle plate 2 are inclined surfaces, and the inclination angle matches the inclined surface of the channel. The side end inclined surfaces of the baffle plate 2 are against the inclined surface of the channel body 1, so that the baffle plate 2 fits closely with the channel body 1 without shaking, which causes collision damage between the baffle plate 2 and the channel body 1. The fixed grooves 401 and the fixed blocks 201 fix and limit the baffle plate 2, and place the baffle plate 2 to slide on the support block 4.

[0027] According to the utility model, a filter plate 3 is installed at a certain distance on the water channel body 1, and a collecting groove 101 is dug at the bottom end of the water channel body 1. The handle 301 is held to slide the filter plate 3 through the fixed slide groove 401, and the filter plate 3 is installed on the water channel body 1, so that the collection frame 5 is fully extended into the collecting groove 101, and then the baffle plate 2 is used to cover the top of the water channel body 1, and the fixed block 201 is extended into the fixed slide groove 401, so that the baffle plate 2 and the water channel body 1 are closely fitted, and at the same time, the front and rear ends of the baffle plates 2 are also fitted to each other, and the baffle plates 2 before and after the filter plate 3 are also with the filter plate 3 is fitted to prevent dead branches and leaves from falling into the canal from the upper end of the canal body 1. After the canal body 1 has been working for a period of time, some debris will flow into the canal body 1 from the upper stream along with the water flow, and the filter plate 3 will block these debris and prevent them from flowing into the farmland. After being blocked, the debris will gradually sink and fall into the collecting frame 5. Therefore, the blocking plate 2 at the front end of the filter plate 3 is disassembled every period of time, and the filter plate 3 is held and pulled out to clean the precipitated debris in the collecting frame 5. After cleaning, the filter plate 3 and the blocking plate 2 are reinstalled to continue filtering and blocking debris.
