Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a water conservancy engineering device for intercepting sluice garbage. Background Art

[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and disasters, and regulate and distribute water.

[0003] First of all, the purpose of setting up sluices is to control the storage and discharge of water, while artificial canals are used to assist irrigation. Artificial canals are built next to mountains to make full use of the terrain and guide water to rice fields. However, due to people's lack of environmental awareness, a large amount of garbage thrown away by people at will is retained in the irrigation canals. When the sluices are opened, the solid waste in the canals will move with the flowing water. If the solid waste accumulates in the bottom groove of the gate during drainage, workers need to open the gates when cleaning. The flow of water will affect the workers' standing and make it inconvenient to operate. In addition, the gates cannot be closed, which makes it difficult to form water storage in the canals in the later stage, affecting the later irrigation use. Summary of the invention

[0004] The object of the present invention is to provide a hydraulic engineering device for intercepting sluice garbage to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention aims to provide a water conservancy engineering device for intercepting sluice garbage, including side plates, gates and a driving device located at the top of the side plates for driving the gates to move up and down, a bottom plate with a groove is fixedly connected to the bottom of the side plates, the groove cooperates with the gate, and a guiding part is arranged between the side plates on both sides of the bottom of the gate symmetrically, the guiding part is used to guide the garbage in the groove to the middle of the groove when the gate moves downward, the middle of the bottom plate has a cavity, a blocking part is arranged in the cavity to separate the cavity from the groove, the blocking part is used to achieve conduction between the groove and the cavity, and a collection box connected with the cavity is arranged in the bottom plate, and a power part connected with the blocking part is arranged on the outside of the side plate of the guide part on one side, the power part is used to push the blocking part upward by using the gas delivered by the power part under the traction of the guide part, so that the garbage guided by the guide part slides into the collection box, so as to bring the collection box out of the water when the gate moves upward.

[0006] As a further improvement of the present technical solution, the guide portion includes a guide plate whose one end is slidably connected to the inner wall of the groove, and the other end of the guide plate is rotatably connected to a slide plate that fits between the side plate and the gate, and the connection position between the slide plate and the guide plate is located at the corner of the gate.

[0007] As a further improvement of the present technical solution, a tension spring is fixedly connected to one end of the guide plate opposite to the slide plate, the tension spring is located in the groove, and the end of the tension spring is fixedly connected to the inner wall of the groove, and a stop block is provided at the end of the guide plate close to the groove, and the stop block protrudes outward to hold back solid waste when the gate is closed.

[0008] As a further improvement of the present technical solution, guide plates are fixedly arranged on both symmetrical sides of the bottom plate located in the water inlet direction. One end of the guide plate near the middle of the bottom plate is inclined in the drainage direction, and the other end extends outward to cover the bottom of the side plate, so that the solid waste in the water flow is guided to the middle of the groove.

[0009] As a further improvement of the present technical solution, the power unit includes a traction rope with one end passing through a tension spring and fixedly connected to the end of the guide plate, and a piston head fixedly connected to the other end of the traction rope. The outside of the piston head is sleeved with a piston cylinder fixedly connected to a side plate. The top of the piston cylinder has an opening, and a return spring arranged in the piston cylinder is against the piston head.

[0010] As a further improvement of the present technical solution, an air supply pipe and an air guide pipe are connected to the bottom of the piston cylinder. The air supply pipe is connected to the air collecting cavity inside the bottom plate. A one-way valve is arranged in the air guide pipe for allowing external air to enter the piston cylinder.

[0011] As a further improvement of the present technical solution, a vertical cylinder is arranged in the cavity, and an air bag connected to the air collecting chamber is provided inside the vertical cylinder. The air bag is connected to an exhaust pipe which runs through the vertical cylinder. The end of the exhaust pipe away from the vertical cylinder extends toward the connection between the cavity and the groove, so that the air discharged from the exhaust pipe can be used to clear the solid waste blocked between the groove and the cavity. When the air collecting chamber inflates the air bag, the air entering the air bag is greater than the air discharged from the exhaust pipe, so as to realize the expansion of the air bag.

[0012] As a further improvement of the technical solution, a circular plate is attached to the top of the airbag for keeping the baffle stable when the baffle is separated from the cavity. The circular plate is slidably connected to the inner wall of the vertical tube, the top of the circular plate is fixedly connected to a vertical pole, and the top of the vertical pole is fixedly connected to a baffle that fits the cavity.

There are material guide grooves on both sides of the cavity. The material guide grooves are connected to the square grooves in the bottom plate for placing the collection boxes. The inner walls of the material guide grooves gradually increase in height from one end of the square groove to the other end. A material guide plate penetrated by a vertical tube and an exhaust pipe is provided between the material guide grooves on both sides. The two ends of the material guide plate close to the material guide groove are higher than the material guide groove, and the material guide plate and the top of the baffle extend from the center to both sides, forming a tilted posture to both sides, so that the solid waste can slide smoothly into the material guide groove.

[0014] As a further improvement of the present technical solution, the collecting box at a position corresponding to the discharge port of the material guide trough has a through groove, a flip plate is rotatably arranged in the through groove, and an insert plate is slidably arranged at the bottom of the collecting box, and the insert plate is used to seal the gap at the bottom of the collecting box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the water conservancy engineering device for intercepting sluice garbage, the downward movement of the gate drives the guiding part to guide the solid garbage in the groove to the middle of the groove, and cooperates with the power part to transport air to the blocking part to push the blocking part out, and the groove, cavity and collection box are connected in sequence, thereby realizing automatic cleaning of garbage and impurities in the groove, reducing the intensity of manual work, and preventing the deposited garbage and stones sliding down from the mountain from affecting the closing of the gate.

[0017] 2.

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. 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 creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0038] like Figure 1 and Figure 2 As shown, a water conservancy engineering device for intercepting sluice garbage is provided, including a side plate 100, a gate 101 and a driving device 102 located at the top of the side plate 100 for driving the gate 101 to move up and down. A bottom plate 110 with a groove is fixedly connected to the bottom of the side plate 100, and the groove cooperates with the gate 101. When the canal needs to store water, the gate 101 is released by the driving device 102 to the bottom of the gate 101 to extend into the groove of the bottom plate 110, and the flow of water is restricted under the obstruction of the gate 101. Conversely, the gate 101 can be opened to carry out irrigation operations.

[0039] Secondly, when the gate 101 is opened, the force of the water flow will flush the solid waste in the canal. This flushing effect causes the waste that was originally stationary in the canal to be swept away by the water flow, thereby causing displacement, causing the solid waste to move into the groove in the bottom plate 110, thereby affecting the closing of the gate 101.

[0040] To this end, combined Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a guide portion 120 is provided between the side plates 100 on both sides of the bottom of the gate 101. The guide portions 120 are used to guide the garbage in the groove to the middle of the groove when the gate 101 moves downward. The bottom plate 110 has a cavity in the middle, and a blocking portion 140 is provided in the cavity to separate the cavity from the groove. The blocking portion 140 is used to achieve conduction between the groove and the cavity. Under the action of the guide portion 120, the solid garbage falling into the groove is collected in the blocking portion. A collecting box 150 connected to the cavity is arranged around the blocking part 140 and inside the bottom plate 110. A power unit 130 connected to the blocking part 140 is arranged outside the side plate 100 of the guide part 120 on one side. The power unit 130 is used to push the blocking part 140 upward by using the gas delivered by the power unit 130 under the traction of the guide part 120, so that the garbage guided by the guide part 120 slides into the collecting box 150, so as to bring the collecting box 150 out of the water when the gate 101 moves upward.

[0041] That is to say, the downward movement of the gate 101 drives the guide part 120 to guide the solid waste in the groove to the middle of the groove, and cooperates with the power part 130 to transport air to the blocking part 140 to push the blocking part 140 out, and the groove, cavity, and collection box 150 are connected in sequence, thereby realizing automatic cleaning of the garbage and impurities inside the groove, reducing the intensity of manual work, and preventing the deposited garbage and rocks sliding down from the mountain from affecting the closing of the gate 101.

[0042] First, through Figure 3 and Figure 4 The structure of the guide portion 120 is further disclosed. The guide portion 120 includes a guide plate 121 at one end of which is slidably connected to the inner wall of the groove, and the other end of the guide plate 121 is rotatably connected to a slide plate 122 that fits between the side plate 100 and the gate 101. The connection position between the slide plate 122 and the guide plate 121 is located at the corner of the gate 101, and one end of the guide plate 121 opposite to the slide plate 122 is fixedly connected to a tension spring 135, the tension spring 135 is located in the groove, and the end of the tension spring 135 is fixedly connected to the inner wall of the groove, and a stop block 123 is provided at the end of the guide plate 121 close to the groove, and the stop block 123 protrudes outward to hold back solid waste when the gate 101 is closed.

[0043] On the other hand, returning to Figure 1 and Figure 2 As shown, guide plates 113 are fixedly arranged on the symmetrical sides of the bottom plate 110 in the water inlet direction, one end of the guide plate 113 near the middle of the bottom plate 110 is inclined in the drainage direction, and the other end extends outward to block the bottom of the side plate 100, so that the solid waste in the water flow is guided to the middle of the groove. In this way, when the gate 101 is opened, the solid waste impacted by the water flow is guided to the middle of the groove under the action of the guide plates 113 on both sides, and in this process, under the elastic action of the tension spring 135, the guide plate 121 gradually changes from the original horizontal state to the inclined state.

[0044] In view of the fact that during the movement of the guide plate 121, solid garbage or stones washed by the water flow will fall into the groove on the back of the guide plate 121, thereby affecting the opening of the guide plate 121, Figure 2 The guide plate 121 gradually moves to form an angle with the bottom plate 110. When the angle is just formed between the guide plate 121 and the bottom plate 110, the angle is blocked by the guide plate 113, thereby preventing solid garbage or stones from moving from the angle into the groove.

[0045] It should be noted that the back of the guide plate 121 mentioned above is Figure 3 For example, the side where the tension spring 135 is located is the back side, and the opposite side is the front side.

[0046] Furthermore, since the power for ejecting the blocking portion 140 comes from the power portion 130, on the basis of the above, the structure of the power portion 130 is publicly disclosed. The power portion 130 includes a traction rope 132 with one end passing through a tension spring 135 and fixedly connected to the end of the guide plate 121, and a piston head 131 fixedly connected to the other end of the traction rope 132. The outer portion of the piston head 131 is sleeved with a piston cylinder 133 fixedly connected to a side plate 100. The top of the piston cylinder 133 has an opening, and a return spring 136 arranged in the piston cylinder 133 is against the piston head 131. When the piston head 131 moves downward, the return spring 136 is compressed and accumulates elastic potential energy, thereby providing power for the piston head 131 to move upward.

[0047] Secondly, the bottom of the piston cylinder 133 is connected with an air supply pipe and an air guide pipe 134 . The air supply pipe is connected with the air collecting chamber 111 inside the bottom plate 110 . A one-way valve is provided in the air guide pipe 134 for allowing external air to enter the piston cylinder 133 .

[0048] Specifically during operation: when the gate 101 is closed, the guide plate 121 pulls the traction rope 132 to move the piston head 131 downward in the piston cylinder 133, and the piston head 131 compresses the return spring 136. The air inside the piston cylinder 133 is transported to the air collecting chamber 111 through the air supply pipe, so as to provide power for pushing the blocking part 140 out later. At this time, the one-way valve in the air guide pipe 134 is in a closed state, and the guide plate 121 pushes the solid waste in the groove to move toward the middle until the guide plate 121 is completely immersed in the groove, and there is a gap between the bottom of the gate 101 and the bottom of the groove to accommodate the tension spring 135 and the guide plate 121.

[0049] On the contrary, when the gate 101 is opened, under the elastic action of the tension spring 135 and the return spring 136, the guide plate 121 gradually changes from a horizontal state to an inclined state, the traction rope 132 is released, the return spring 136 pushes the piston head 131 upward to move, and draws external air into the piston cylinder 133 through the air guide tube 134 for temporary storage for the next use.

[0050] Combine the following Figure 5 and Figure 6 As shown, a vertical cylinder 160 is provided in the cavity, and an air bag 161 connected to the air collecting chamber 111 is provided inside the vertical cylinder 160. The air bag 161 is connected to an exhaust pipe 170 that passes through the vertical cylinder 160. The end of the exhaust pipe 170 away from the vertical cylinder 160 extends toward the connection between the cavity and the groove, so that the air discharged from the exhaust pipe 170 can be used to clear the solid waste blocked between the groove and the cavity.

[0051] When the air collecting chamber 111 inflates the airbag 161 , the air entering the airbag 161 is greater than the air discharged from the exhaust pipe 170 , so that the airbag 161 is expanded.

[0052] Secondly, when the baffle 141 is pushed upward to connect the groove with the cavity, the bubbles overflowing from the exhaust pipe 170 can also clear the sludge and solid waste stuck at the connection between the groove and the cavity, thereby improving the cleaning effect. The reason is that by overflowing the bubbles from the exhaust pipe 170 and utilizing the buoyancy and flushing effect of the bubbles, the sludge and solid waste located at the connection between the groove and the cavity can be effectively cleared.

[0053] In addition, in order to push out the baffle 141 by expanding the airbag 161, a circular plate 142 is attached to the top of the airbag 161 to keep the baffle 141 stable when the baffle 141 is separated from the cavity. The circular plate 142 is slidably connected to the inner wall of the vertical tube 160, and a vertical rod is fixedly connected to the top of the circular plate 142. The baffle 141 that fits the cavity is fixedly connected to the top of the vertical rod. Figure 6 Based on and combined with Figure 7 and Figure 8 As shown, compression springs 143 are elastically connected between the bottom of both sides of the baffle 141 and the inner wall of the cavity, and guide grooves 112 are provided on both sides of the cavity. The guide grooves 112 are connected to the square grooves in the bottom plate 110 for placing the collection box 150. The inner wall of the guide groove 112 gradually increases in height from one end of the square groove to the other end. A guide plate 171 penetrated by the vertical cylinder 160 and the exhaust pipe 170 is provided between the guide grooves 112 on both sides. Both ends of the guide plate 171 close to the guide groove 112 are higher than the guide groove 112, and the guide plate 171 and the top of the baffle 141 extend from the center to both sides, forming a posture inclined to both sides, so that the solid waste can slide smoothly into the guide groove 112.

[0054] Working principle: During the expansion of the airbag 161, the airbag 161 pushes the circular plate 142 upward. The expanded airbag 161 overcomes the elastic potential energy of the compression springs 143 on both sides of the baffle 141 and pushes the circular plate 142 upward, so that the height of the baffle 141 is raised upward until the groove is connected to the cavity. Figure 2 and Figure 3 As shown, the solid waste in the groove is pushed into the cavity by the guide plates 121 on both sides, and the solid waste moves into the guide trough 112 through the guide plate 171, and then the solid waste in the guide trough 112 moves into the collection box 150, and the collection box 150 is brought upward when the gate 101 is opened, thereby realizing automatic cleaning of the solid waste in the canal and reducing the labor intensity of the workers.

[0055] In addition, Figure 8 Based on and combined with Fig. 9As shown, a through groove is provided on the collecting box 150 at a position corresponding to the discharge port of the material guide trough 112, and a flip plate 151 is rotatably arranged in the through groove. A plug plate 152 is slidably arranged at the bottom of the collecting box 150, and the plug plate 152 is used to block the gap at the bottom of the collecting box 150. Therefore, the solid waste in the material guide trough 112 will push the flip plate 151 open and fall into the collecting box 150. When the gate 101 moves upward and out of the water surface, the worker pulls the plug plate 152 to discharge the solid waste. The operation is simple.

[0056] It should be pointed out that: when the baffle 141 moves upward to the maximum displacement, that is, the compression spring 143 is stretched to the maximum stroke, the baffle 141 does not contact the bottom of the gate 101, and the groove is connected to the cavity. At this time, the collecting box 150 is still in the square groove and moves downward. The side wall of the collecting box 150 blocks the solid waste in the guide trough 112 to prevent the solid waste in the guide trough 112 from falling into the square trough when the bottom of the collecting box 150 is not lower than the lower edge of the discharge port of the guide trough 112, thereby affecting the recovery of the solid waste.

[0057] In summary, when the baffle 141 is reset downward and fits against the inner wall of the cavity, the groove is now separated from the cavity, and when the gate 101 is opened, the solid waste collected in the collection box 150 is taken out, thereby achieving automatic cleaning of the solid waste.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
