Description

Technical Field

[0001] The invention belongs to the technical field of sluices, in particular to a sluice for drawing water from farmland. Background Art

[0002] Most crops grown in farmland require a constant supply of water, especially during the seedling and heading stages. Failure to do so will result in reduced harvests and, indirectly, substandard crop production. Existing technical solutions typically involve rapidly releasing water through sluice gates. This eliminates the need for farmers to contact pumps, reducing workload and economic burden while also allowing crops to quickly absorb water. A sluice gate is a hydraulic facility that regulates water levels and controls flow by opening and closing gates. It typically consists of a lock chamber, gates, a hoist, and upstream and downstream connecting sections.

[0003] However, since the sluice gate is located in the farmland, and there is a high probability that there will be a lot of garbage in the river between the fields, such as pesticide bottles, wheat straw, and kitchen waste from lunch, these garbage are very likely to get stuck in the gate slot when the gate is opened, causing the gate to fail to fall completely and cause water leakage. The crops near the sluice gate may also be drowned due to excessive water. Summary of the Invention

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a water gate for drawing water from farmland, which solves the problem that when the water gate is releasing water, garbage is trapped in the gate groove, causing the gate to be unable to fall completely, subsequent water leakage, and causing crops around the water gate to absorb too much water and be drowned.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a water gate for drawing water from farmland, comprising a concrete slab;

[0006] An isosceles trapezoidal foundation is provided in the middle of the concrete slab, and a gate is vertically slidably provided on the concrete slab;

[0007] The top of the foundation is provided with a gate groove for engaging with the gate, and a group of first water troughs are equidistantly provided inside the foundation. The ends of the first water troughs are provided with a group of inlets extending to one side of the foundation, and the first water troughs are connected to a second water trough extending to the other side of the foundation;

[0008] The inlet end of the first water trough is arranged horizontally, the first water trough is connected to the door groove and the connecting end is arranged vertically, and the horizontal end and the vertical end are connected by an inclined channel;

[0009] The interior of the foundation is connected with a sealing block through a group of hydraulic cylinders. The sealing block is located in the middle of the second water tank. A notch adapted to the second water tank is opened on the sealing block.

[0010] Preferably, a second anti-blocking component is provided inside the concrete slab;

[0011] The second anti-blocking component includes a bracket arranged inside the concrete slab, and a group of filter cages are connected to the side of the bracket through metal rods, and each filter cage is respectively located at each inlet end of the first water tank.

[0012] Preferably, the filter cage is welded by a plurality of steel bars, and the bracket slides inside the foundation.

[0013] Preferably, the anti-blocking component 2 further includes a set of elastic members 2, a set of guide plates 1 vertically sliding inside the foundation, and a set of guide plates 2 horizontally sliding inside the foundation, and each of the guide plates 1, the bracket, and the guide plate 2 are connected to the foundation via corresponding elastic members 2 respectively;

[0014] The bottom of the guide plate 1 and the side of the bracket are inclined to each other, the top of the guide plate 1 and one side of the guide plate 2 are inclined to each other, and the other side of the guide plate 2 is inclined.

[0015] Preferably, an anti-blocking component 1 is installed on each side of the concrete slab;

[0016] Two tooth plates corresponding to the anti-blocking components are installed on the side of the gate;

[0017] The anti-blocking component 1 includes a gear rotatably mounted on the side of the concrete slab, the gear meshing with the toothed plate, the gear being connected to a linkage shaft via a transmission belt, and a water pipe communicating with the first water tank being provided inside the concrete slab;

[0018] The end of the linkage shaft is located inside the water pipe and is equipped with a water pump, which is used to extract water from the riverbank.

[0019] Preferably, there are two water pumps in each anti-blocking component and their structures are opposite. Both water pumps are located inside the water pipe. A metal filter is provided at the water inlet end of the water pipe. The diameter of the gear is greater than the diameter of the linkage shaft.

[0020] Preferably, the water pump comprises spring telescopic rods equidistantly arranged in an annular array on the outer periphery of the linkage shaft, the ends of the spring telescopic rods are mounted with beveled tooth plates, an impeller is rotatably mounted on the outer periphery of the linkage shaft, and a ratchet is provided inside the impeller that engages with the beveled tooth plates;

[0021] The inner wall array of the water pipe is provided with two elastic members 1, and the outer side array of the impeller is provided with two barbs;

[0022] The elastic member 1 is buckled with the corresponding barb.

[0023] Preferably, a metal hook corresponding to the barb is provided at the end of the elastic member 1, and the elastic member 1 is in an arc shape.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention cooperates with structures such as the foundation and concrete slabs. According to the water pressure difference, the water on the side of the foundation always flows and pushes the water into the first water trough. The water inside the gate groove will always spray upward and be carried away by the water flowing above the foundation. The water pressure on the gate groove will prevent garbage from entering. The notch on the sealing block is connected to the second water trough. Water needs to overcome gravity to enter the gate groove upward and will also lose potential energy when it hits the bend of the first water trough. It will flow directly away through the second water trough. The suction force at the end of the first water trough increases and extracts a part of the silt, reducing the possibility of the end of the first water trough being blocked. The above working process can effectively reduce the possibility of garbage existing in the gate groove, and reduce the possibility of water leakage after the subsequent gate is closed, thereby providing safety protection for the growth of crops.

[0026] The present invention cooperates with structures such as the anti-blocking component 2 and the gate. When the filter cage is located inside the first water trough, it can prevent garbage from being thrown on the river surface and damaging the filter cage, thereby reducing its garbage interception performance. At the same time, it can prevent aquatic plants from attaching to the filter cage and block the end of the first water trough when it is not used for a long time. When the gate rises, the filter cage moves outward and increases the interception area. When the garbage is intercepted by the filter cage, the water flow is always guided by the inclined surface of the foundation, so the garbage will be tightly inserted into the filter cage. However, due to the inclined flow of water, most of the garbage is inserted around the filter cage, and its sides can allow water to flow normally, which will not affect the operation of the device.

[0027] The present invention cooperates with an anti-blocking component and a gate and other structures. When the linkage shaft rotates clockwise, the spring telescopic rod supports the beveled tooth plate to engage with the ratchet, and the impeller rotates to draw water into the water pipe, while the barb passes over the elastic member 1. The two will not be able to engage under the guidance of the above-mentioned rotation direction. When the gate drops, the linkage shaft rotates counterclockwise, and the barb and the elastic member 1 will engage together, thereby preventing the impeller from rotating. The beveled tooth plate and the ratchet can no longer engage and transmit according to their own inclined teeth. Since the structural setting of the other water pump is opposite to that of the above-mentioned water pump, the other water pump will continue to work, thereby increasing the water pressure inside the first water tank, so that garbage cannot easily enter the door slot when the gate is closed and the water flow rate is reduced.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figures 1 to 11 As shown, the present invention provides a sluice for drawing water from farmland, comprising a concrete slab 1;

[0042] An isosceles trapezoidal foundation 4 is provided in the middle of the concrete slab 1, and a gate 3 is vertically slidably provided on the concrete slab 1;

[0043] The top of the foundation 4 is provided with a gate groove 41 for engaging with the gate 3. A group of first water troughs 42 are equidistantly provided inside the foundation 4. A group of inlets are provided at the ends of the first water troughs 42 and extend to one side of the foundation 4. A second water trough 43 is connected to the first water trough 42 and extends to the other side of the foundation 4.

[0044] The inlet end of the first water trough 42 is arranged horizontally, the first water trough 42 is connected to the door groove 41 and the connecting end is arranged vertically, and the horizontal end and the vertical end are connected by an inclined channel;

[0045] The interior of the foundation 4 is connected to a sealing block 45 via a group of hydraulic cylinders 44 . The sealing block 45 is located in the middle of the second water trough 43 . A notch adapted to the second water trough 43 is formed on the sealing block 45 .

[0046] Adopting the above solution: when the screw motor 2 drives the gate 3 sliding vertically on the concrete slab 1 to rise;

[0047] The hydraulic cylinder 44 now pulls the sealing block 45 to block the second water tank 43;

[0048] At this time, the water flows toward the end of the second water tank 43, and a portion of it enters the end of the first water tank 42;

[0049] like Figure 6 As shown in the schematic diagram of water flow direction, according to the water pressure difference, when the water above the foundation 4 flows, it will extract a portion of the water in the gate groove 41, and the gate groove 41 is connected to the first water groove 42, and the water on the side of the foundation 4 always flows and pushes the water into the first water groove 42;

[0050] The water inside the gate slot 41 will always spray upward and be carried away by the water flowing above the foundation 4. When garbage is at the top of the foundation 4 and is about to enter the gate slot 41, the water pressure on the gate slot 41 will prevent the garbage from entering.

[0051] Furthermore, a plurality of first water troughs 42 are provided, and a plurality of water inlet ends of each first water trough 42 are also provided and arranged equidistantly in the vertical direction on the side of the foundation 4. Therefore, even if there is a lot of silt in the riverbed, it will not affect the water inflow of the first water trough 42 too much. In farmland, water needs to be released frequently to avoid low quality of crops. Therefore, the riverbed is washed for a long time, and the silt at the bottom is not much, so it will not cause excessive impact on the operation of the device.

[0052] When there is too much silt in the riverbed, the sealing block 45 is pushed by the hydraulic cylinder 44 so that the notch on the sealing block 45 engages with the second water trough 43. After the water enters the first water trough 42, the water needs to overcome gravity to enter the door groove 41 upwards and will also lose some potential energy when hitting the bend of the first water trough 42. Therefore, the water will flow directly through the second water trough 43. At this time, the water flow rate will be accelerated and the suction force at the end of the first water trough 42 will also increase, so some of the silt will be absorbed. As the water discharge time increases, the silt will become loose, making it easier to be absorbed and discharged by the first water trough 42. This can reduce the possibility of the end of the first water trough 42 being blocked, and at the same time improve the anti-blocking performance of the device.

[0053] The above-mentioned working process can effectively reduce the possibility of garbage existing inside the gate slot 41 and reduce the possibility of water leakage after the subsequent gate 3 is closed, thereby providing safety protection for the growth of crops.

[0054] like Figure 1-Figure 7 As shown, an anti-blocking component 6 is provided inside the concrete slab 1;

[0055] The second anti-blocking component 6 includes a bracket 61 arranged inside the concrete slab 1 , and a group of filter cages 62 are connected to the side of the bracket 61 through metal rods. Each filter cage 62 is located at each inlet end of the first water tank 42 .

[0056] The filter cage 62 is welded by a plurality of steel bars, and the bracket 61 slides inside the foundation 4 .

[0057] With the above solution, before water enters the first water tank 42, it will enter the contact filter cage 62 in advance, thereby intercepting garbage that may enter the first water tank 42. When garbage is inserted into the filter cage 62, since the side of the foundation 4 is inclined, all water flows inclined and flows upward, and some garbage that cannot be firmly inserted into the filter cage 62 will be carried away by the water flow, further preventing the first water tank 42 from being blocked and improving the anti-blocking effect of the device.

[0058] like Figure 1-Figure 7 As shown, the anti-blocking assembly 2 6 also includes a set of elastic members 2 611. A set of guide plates 1 63 slides vertically inside the foundation 4, and a set of guide plates 2 64 slides horizontally. Each guide plate 1 63, bracket 61, and guide plate 2 64 are connected to the foundation 4 via corresponding elastic members 2 611.

[0059] The bottom of the guide plate 1 63 and the side of the bracket 61 are inclined to each other, the top of the guide plate 1 63 and one side of the guide plate 2 64 are inclined to each other, and the other side of the guide plate 2 64 is inclined.

[0060] The above solution prevents the filter cage 62 from being damaged by garbage thrown onto the river surface, thereby reducing its garbage interception performance. It also prevents aquatic plants from adhering to the filter cage 62 and blocks the end of the first water trough 42 when the filter cage 62 is not used for a long time.

[0061] When the gate 3 rises, it no longer blocks the second guide plate 64. The second elastic member 611 pushes the second guide plate 64, and the first guide plate 63 is pushed by the corresponding second elastic member 611. The second elastic member 611 pushes the corresponding bracket 61, causing the filter cage 62 to move outward and increase the interception area. When the garbage is intercepted by the filter cage 62, the water flow is always guided by the inclined surface of the foundation 4, so the garbage will be tightly attached to the filter cage 62. However, due to the inclined flow of water, most of the garbage is attached to the sides of the filter cage 62, and the sides can allow water to flow normally, thereby not affecting the operation of the device.

[0062] When the gate 3 descends but does not contact the second guide plate 64, the water flow rate decreases, and the staff can enter to clean the garbage on the filter cage 62, thereby further reducing the amount of garbage in the river and effectively reducing the possibility of the first water tank 42 being blocked at the water inlet when the device works next time;

[0063] The inclined surface of the guide plate 2 64 can make it easier to be pushed downward by the gate 3 without causing any jamming, and can improve the smoothness of the device operation.

[0064] like Figures 1-11 As shown, an anti-blocking component 5 is installed on each side of the concrete slab 1;

[0065] Two tooth plates 31 corresponding to the anti-blocking component 5 are installed on the side of the gate 3;

[0066] The anti-blocking component 1 5 includes a gear 51 rotatably mounted on the side of the concrete slab 1, the gear 51 meshes with the toothed plate 31, and the gear 51 is connected to a linkage shaft 53 via a transmission belt 52. A water pipe 54 connected to the first water tank 42 is provided inside the concrete slab 1;

[0067] The end of the linkage shaft 53 is located inside the water pipe 54 and is installed with a water pump 55, which is used to pump water from the river bank.

[0068] There are two water pumps 55 in each anti-blocking component 5 and their structures are set oppositely. Both water pumps 55 are located inside the water pipe 54. A metal filter is set at the water inlet end of the water pipe 54. The diameter of the gear 51 is greater than the diameter of the linkage shaft 53.

[0069] With the above solution, when the gate 3 rises, the tooth plate 31 drives the gear 51 to rotate, and the gear 51 drives the linkage shaft 53 to rotate through the transmission belt 52. The linkage shaft 53 drives the water pump 55 thereon to pump water into the water pipe 54. The water pipe 54 is also connected to the first water tank 42. This can effectively enhance the pressure of the water outflow from the first water tank 42, and can also prevent larger or heavier garbage from entering when it passes through the top of the gate slot 41.

[0070] When the gate 3 is lowered, the water pump 55 that was previously pumping water will be closed, and the other water pump 55 will continue to pump water. When the gate 3 is lowered and the water flow rate is reduced, the gate slot 41 can still spray water upward to continue to intercept garbage, which further reduces the possibility of garbage being present in the gate slot 41.

[0071] A metal filter is provided at the end of the water pipe 54 to reduce the amount of garbage that is thrown towards the water pump 55 due to the guidance of the water flow.

[0072] It should be noted that the transmission area of ​​the gear 51 is much larger than that of the linkage shaft 53 , which increases the rotation speed of the linkage shaft 53 , thereby increasing the water pressure and further preventing more garbage from entering the door slot 41 .

[0073] like Figures 1-11 As shown, the water pump 55 includes spring telescopic rods 551 arranged equidistantly around the outer periphery of the linkage shaft 53. The ends of the spring telescopic rods 551 are mounted with beveled tooth plates 552. An impeller 554 is rotatably mounted on the outer periphery of the linkage shaft 53. A ratchet 553 is provided inside the impeller 554 and engages with the beveled tooth plates 552.

[0074] The inner wall array of the water pipe 54 is provided with two elastic members 555, and the outer side array of the impeller 554 is provided with two barbs 556;

[0075] The elastic member 1 555 and the corresponding barb 556 are engaged with each other.

[0076] A metal hook corresponding to the barb 556 is provided at the end of the elastic member 1 555 , and the elastic member 1 555 is in an arc shape.

[0077] Adopt the above scheme: Figure 10 In the illustrated water pump 55 , when the anti-blocking assembly 1 5 is raised and the linkage shaft 53 rotates clockwise, the spring-loaded telescopic rod 551 pushes against the beveled tooth plate 552 to engage with the ratchet 553 , causing the impeller 554 to rotate and draw water into the water pipe 54 . The barb 556 then passes over the elastic member 1 555 , preventing the two from engaging under the aforementioned rotational direction.

[0078] When the gate 3 descends, the linkage shaft 53 rotates counterclockwise, and the barb 556 and the elastic member 555 will be engaged together, so that the impeller 554 cannot rotate, and the bevel plate 552 and the ratchet 553 can no longer engage and transmit according to their own inclined teeth. Since the other water pump 55 is opposite to the structural setting of the above-mentioned water pump 55, the other water pump 55 will continue to work, thereby increasing the water pressure inside the first water tank 42, so that garbage cannot easily enter the door slot 41 when the gate 3 is closed and the water flow speed is reduced.

[0079] The working principle and use process of the present invention:

[0080] When the screw motor 2 drives the gate 3 that slides vertically on the concrete slab 1 to rise, the water flows toward the end of the second water tank 43, and a portion of the water flows into the end of the first water tank 42;

[0081] According to the water pressure difference, when the water above the foundation 4 flows, it will extract a part of the water in the gate groove 41, and the gate groove 41 is connected to the first water tank 42, and the water on the side of the foundation 4 always flows and pushes the water into the first water tank 42;

[0082] The water inside the gate slot 41 will always spray upward and be carried away by the water flowing above the foundation 4. When garbage is at the top of the foundation 4 and is about to enter the gate slot 41, the water pressure on the gate slot 41 will prevent the garbage from entering.

[0083] When the gate 3 rises, it no longer blocks the second guide plate 64. The second elastic member 611 pushes the second guide plate 64, and the first guide plate 63 is pushed by the corresponding second elastic member 611. The second elastic member 611 pushes the corresponding bracket 61, causing the filter cage 62 to move outward and increase the interception area. When the garbage is intercepted by the filter cage 62, the water flow is always guided by the inclined surface of the foundation 4, so the garbage will be tightly attached to the filter cage 62. However, due to the inclined flow of water, most of the garbage is attached to the sides of the filter cage 62, and the sides can allow water to flow normally.

[0084] When the gate 3 rises, the toothed plate 31 drives the gear 51 to rotate, and the gear 51 drives the linkage shaft 53 to rotate through the transmission belt 52;

[0085] When the linkage shaft 53 rotates clockwise, the spring-loaded telescopic rod 551 pushes the beveled tooth plate 552 to engage with the ratchet 553, and the impeller 554 rotates to pump water into the water pipe 54. The barb 556 passes over the elastic member 1 555, and the two are unable to engage under the guidance of the above rotation direction.

[0086] When the gate 3 descends, the linkage shaft 53 rotates counterclockwise, and the barb 556 and the elastic member 555 will be engaged together, so that the impeller 554 cannot rotate, and the bevel plate 552 and the ratchet 553 can no longer engage and transmit according to their own inclined teeth. Since the other water pump 55 is opposite to the structural setting of the above-mentioned water pump 55, the other water pump 55 will continue to work, thereby increasing the water pressure inside the first water tank 42, so that garbage cannot easily enter the door slot 41 when the gate 3 is closed and the water flow speed is reduced.
