Description

Technical Field

[0001] The present invention relates to the technical field related to farmland water conservancy, and more specifically, to a farmland water channel flood control mechanism. Background Art

[0002] A canal is a waterway dug by workers. Usually, a ditch is dug on the ground and then built with stone or concrete. It is often used for farmland irrigation. Water is often released from canals during the irrigation season of farmland. For example, rice fields in the south are often released from late March to early April, and the ripening season is from mid-June to mid-July. However, since June and July are rainy seasons, rainy weather can easily cause waterlogging. Rainwater sometimes overflows the canals, impacting rice fields and causing large-scale reductions in grain production.

[0003] Chinese patent application number 202022343560.0 discloses a liftable flood control baffle, which uses an electric winch to collect the traction rope to raise the baffle, thereby increasing the blocking height. However, the baffle is expensive and is not suitable for large-area installation.

[0004] A Chinese patent with application number 202123301987.5 discloses a flood baffle. Through a support adjustment device and an auxiliary support device, the device can not only fix the flood baffle well under different terrains, but also support and fix the upper and lower parts of the rear end of the flood baffle well, thereby improving the stability of the flood baffle. However, the installation of the baffle requires too much human intervention, and it is difficult to work in time when a flood occurs, which affects the flood control effect of the baffle.

[0005] In response to the above problems, we propose a flood prevention mechanism that can automatically lift the baffle when flooding occurs. Summary of the invention

[0006] The present invention provides a farmland canal flood control mechanism to overcome the problems of high cost of current flood control baffles and slow response speed during floods raised in the above background technology.

[0007] The technical solution of the present invention is as follows:

[0011] A baffle, the bottom end of which is rotatably mounted on the upper end of the inclined surface of the side plate through a hinge, and a plurality of baffles are arranged side by side along the length direction of the side plate and the side walls are closely attached;

[0012] A traction part, the traction part includes a counterweight block and a first traction rope, the counterweight block is movably installed inside the hollow structure on both sides of the water channel body and the side plate, the counterweight block is connected to the first traction rope, and the first traction rope passes through the side plate and is connected to the back of the baffle;

[0013] A positioning part, the positioning part comprises a positioning piece, one end of the positioning piece is movably mounted with the counterweight block and supports the counterweight block to be suspended in the air, and the other end of the positioning piece penetrates the side plate and is connected to the front part of the baffle;

[0014] A first floating block is fixedly mounted on the top of the baffle.

[0015] In the above embodiment, when the water level rises, the first floating block can drive the baffle to gradually become horizontal. When the water level reaches the critical point, the baffle continues to rise. At this time, the front end of the baffle pulls the positioning part to allow the positioning part to separate from the support of the counterweight block. The counterweight block falls instantly. At the same time, under the action of the gravity of the counterweight block, the baffle will be pulled up by the first traction rope, so that the baffle is lifted. Under the action of the gravity of the counterweight block and the water pressure, the baffle will stand firmly on both sides of the canal, thereby raising the height of both sides of the canal. Multiple baffles work together to effectively prevent floods.

[0016] Preferably, the water channel body and the side panels are detachably mounted; a slot is reserved at the top of the side surface of the water channel body for being fixedly connected with the top of the side panel.

[0017] It is convenient to disassemble and maintain the side panels.

[0018] Further preferably, the bottom end of the inner wall of the water channel body is fixedly mounted with limit blocks whose number and positions correspond to those of the side panels.

[0019] Preferably, the inclined surface of the side plate is provided with a first traction rope installation hole and a positioning member installation hole in sequence from top to bottom; the first traction rope passes through the side plate through the first traction rope installation hole; and the positioning portion passes through the side plate through the positioning member installation hole.

[0020] Further preferably, the positioning member mounting hole is arranged perpendicular to the inclined surface of the side panel.

[0021] Further preferably, it also includes a ring, which is fixedly mounted on the inner wall of the canal body through a connecting rod, a ring through hole is vertically arranged in the middle of the ring, the first traction rope passes through the ring through the ring through the ring through the ring through the ring through the ring through the ring, and a socket is reserved on the side of the ring to pass through its side wall.

[0022] Further preferably, the positioning member is a needle-shaped member, one end of the positioning member passes through the positioning member insertion hole and enters the ring, and the other end of the positioning member is connected to a second traction rope, and the second traction rope is connected to the front part of the baffle.

[0023] Preferably, it further comprises a second floating block, wherein a plurality of second floating blocks are provided, and the plurality of second floating blocks are evenly and fixedly installed on the front part of the baffle.

[0024] When the baffle rotates and reaches the critical height, since the positioning piece is inserted into the ring and fixes the first traction rope, providing a second float block can further increase the buoyancy, facilitate quick extraction of the positioning piece, and improve response time.

[0025] Further preferably, the first floating block and the second floating block are both foam blocks.

[0026] Preferably, a drainage hole penetrating through the inclined surface of the side plate is provided at the bottom of the side plate, and the drainage hole is connected to both sides of the side plate.

[0027] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0028] The present invention provides a farmland canal flood control mechanism, which is suitable for canal flood control during flood season. When the canal water level exceeds a critical value, the baffle can be quickly lifted to form shielding protection, specifically:

[0029] By providing the side panels, hinges, the first floating block and the second floating block, when the water level rises, the first floating block and the second floating block can make the side panels gradually tend to be horizontal; by providing the traction part and the positioning part, when the side panel is at a critical value, it will trigger the positioning part when it is lifted up again, and the positioning part will be separated from the traction part by pulling. The counterweight block on the traction part will fall down instantly at this moment, thereby pulling the back of the baffle to lift the baffle, forming a side shield for the channel to prevent floods.

DETAILED DESCRIPTION

[0036] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0037] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0039] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0040] Example 1

[0041] See also Figure 1-5 , a farmland canal flood control mechanism, comprising:

[0042] The main body 1 of the water channel is made of concrete;

[0043] The side panels 2 are obliquely installed on both sides of the inner part of the canal body 1, and a plurality of side panels 2 are arranged side by side along the length direction of the canal body 1 and the side walls are closely attached; the side panels 2 are prefabricated, and the manufactured side panels 2 are stacked one by one on both sides of the inner part of the canal body 1 to facilitate subsequent maintenance.

[0044] The baffle 5, the bottom end of the baffle 5 is rotatably mounted on the upper end of the inclined surface of the side panel 2 through a hinge 6, and a plurality of baffles 5 are arranged side by side along the length direction of the side panel 2 and the side walls are closely attached; the baffle 5 can be made of acrylic plate or hollow metal plate, etc., which has a certain buoyancy while ensuring rigidity. When there is no water in the canal, it is usually in a natural falling state, and the first traction rope 11 is relaxed at this time.

[0045] The traction part includes a counterweight 10 and a first traction rope 11. The counterweight 10 is movably installed inside the hollow structure on both sides of the channel body 1 and the side plate 2. The counterweight 10 is connected to the first traction rope 11. The first traction rope 11 passes through the side plate 2 and is connected to the back of the baffle 5. The first traction rope 11 is in a relaxed state before the positioning part is not triggered. The first traction rope 11 can adopt several braids of steel wire rope to ensure rigidity and rust prevention.

[0046] The positioning part includes a positioning piece 14, one end of the positioning piece 14 is movably installed with the counterweight 10 and supports the counterweight 10 to be suspended in the air, and the other end of the positioning piece 14 passes through the side plate 2 and is connected to the front of the baffle 5; the positioning part is mainly arranged that when the height of the baffle 5 reaches a critical value, further lifting will pull the positioning part, so that the positioning part will be separated from the support of the counterweight 10 on the traction part, so that the counterweight 10 falls, thereby pulling the baffle 5, forming a chain reaction, so that it is lifted, and the whole process responds quickly during the flood season.

[0047] The first floating block 7 is fixedly mounted on the top of the baffle 5; the first floating block 7 provides an upward buoyancy for the baffle 5, which constitutes a triggering condition for the subsequent positioning part to be triggered.

[0048] The water channel body 1 and the side panels 2 are detachable and installable; a slot 3 for clamping and fixing with the top of the side panel 2 is reserved at the top of the side of the water channel body 1, so as to facilitate clamping and installing the side panel 2.

[0049] Furthermore, a limit block 4 corresponding in number and position to the side plate 2 is fixedly installed at the bottom end of the inner wall of the canal body 1, which cooperates with the above-mentioned slots 3 to limit the top and bottom of the side plate 2, thereby achieving a fixing effect.

[0050] The inclined surface of the side plate 2 is provided with a first traction rope installation hole 12 and a positioning member installation hole 13 in sequence from top to bottom; the first traction rope 11 passes through the side plate 2 through the first traction rope installation hole 12; the positioning part passes through the side plate 2 through the positioning member installation hole 13.

[0051] Furthermore, the positioning member mounting hole 13 is arranged perpendicular to the inclined surface of the side plate 2 .

[0052] In the above embodiment, the positioning member mounting hole 13 is inclined so that when the side panel 2 is lifted to a critical height, the inclination angle of the positioning member 14 can be close to the positioning member mounting hole 13, so as to facilitate quick detachment. If it is set horizontally, the positioning member 14 will increase the friction with the wall of the positioning member mounting hole 13, which may cause the detachment time of the positioning member 14 to be slower, affecting the response time.

[0053] Example 2

[0054] See also Figure 5On the basis of the above embodiment, a farmland canal flood control mechanism also includes a collar 8, which is fixedly mounted on the inner wall of the canal body 1 through a connecting rod 9, a collar through hole 18 is vertically arranged in the middle of the collar 8, a first traction rope 11 passes through the collar 8 through the collar through hole 18, and a socket 19 is reserved on the side of the collar 8 to pass through its side wall.

[0055] Furthermore, the positioning member 14 is a needle-shaped member, one end of the positioning member 14 passes through the positioning member insertion hole 19 and penetrates into the ring 8 , and the other end of the positioning member 14 is connected to the second traction rope 15 , and the second traction rope 15 is connected to the front of the baffle 5 .

[0056] In this embodiment, the supporting structure of the traction part and the positioning part is specifically described, so that the first traction rope 11 is passed through the ring 8, and the positioning member 14 is passed through the insertion hole 19, so as to fix the first traction rope 11, and further limit the height of the counterweight 10.

[0057] Example 3

[0058] See also Figure 1-3 Based on Example 1, a farmland canal flood control mechanism also includes a second floating block 16, and a plurality of second floating blocks 16 are provided, and the plurality of second floating blocks 16 are evenly and fixedly installed in front of the baffle 5.

[0059] When the baffle 5 rotates and reaches the critical height, since the positioning member 14 is inserted into the ring 8 and fixes the first traction rope 15, the second floating block 16 can further increase the buoyancy, facilitate the rapid extraction of the positioning member 14, and improve the response time.

[0060] Furthermore, the first floating block 7 and the second floating block 16 are both foam blocks.

[0061] Example 4

[0062] See also Figure 1-3 Based on Example 1, a drainage hole 17 penetrating the inclined surface of the side plate 2 is provided at the bottom thereof, and the drainage hole 17 communicates with both sides of the side plate 2 .

[0063] During the rainy season, rainwater will enter the hollow structure of the canal body 1 and the side panel 2 through the gap between the canal body 1 and the side panel 2, as well as the first traction rope installation hole and the second traction rope installation hole. By setting the drainage hole 17, the water inside the hollow structure can be discharged to avoid water accumulation inside.

[0064] The specific working principle of the present application is as follows: during the flood season, water flows in the canal body 1, and under the action of the first floating block 7 and the second floating block 16, the baffle 5 will be lifted around the hinge 6. When the height of the baffle 5 reaches a critical value, the front of the baffle 5 will pull the second traction rope 15, and the second traction rope 15 will further pull the positioning member 14 to disengage the positioning member 14 from the socket 19 on the ring 8. At this time, the first traction rope 11 in the ring 8 is no longer supported. Under the action of gravity, the counterweight 10 falls instantly, thereby pulling the back of the baffle 5 through the first traction rope 11, lifting the baffle 5 and forming a barrier on both sides of the canal body 1.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
