Description

Technical Field

[0001] The present invention relates to the technical field of slope protection monitoring, and specifically to a liquid level and slope protection monitoring device for water conservancy projects. Background Art

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. Water conservancy projects can be classified according to their purposes and service objects into: water conservancy projects for flood prevention and water conservancy projects for agricultural production. Among them, water conservancy projects for agricultural production specifically include: water conservancy projects for agricultural services to prevent drought, waterlogging, and waterlogging disasters and irrigation and drainage agricultural service water conservancy projects.

[0003] In rural areas, for the convenience of irrigation and drainage, irrigation and drainage channels are mostly dug in areas where farmland is concentrated to introduce the natural river water flow from the upper reaches, so as to facilitate regular irrigation or drought-proof irrigation of farmland crops. These channels generally surround the farmland concentration area, so there will be bent channels following the bending of the farmland. And to ensure the safety of the irrigation channels, slope protection construction needs to be carried out on both sides of the slopes.

[0004] The existing slope protection methods are divided into two types. One is slope protection by laying stones, and the other is slope protection by net surface interception. The former has strong structural stability, but the slope surface and irrigation water are completely blocked, affecting the ecological balance of aquatic organisms (especially for some areas where aquaculture and rice co-cropping are currently carried out, the unbalanced environment is likely to affect water quality, thus affecting the balance of co-cropping). The latter ensures the ecological balance, however, with the continuous scouring of water flow, it will cause a certain amount of soil erosion. Especially in the bending area, the concave bank will be affected by a certain water flow impact force, causing more soil erosion. Over the years, it may cause the collapse of the slope section. Therefore, a liquid level and slope protection monitoring device for water conservancy projects is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a liquid level and slope protection monitoring device for water conservancy projects, which solves the problem that the existing slope protection devices are difficult to achieve both ensuring ecological balance and avoiding soil erosion. By dividing the slope surface into an above-water part and an underwater part, the part underwater prone to soil erosion is regulated, while the part above water that needs to maintain ecological balance is not changed, so as to achieve the slope protection effect.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A liquid level and slope protection monitoring device for water conservancy projects, including slope protection plates, ecological holes, push rods, installation cross bars, connecting rods and floating plates, further comprising a control component. The slope protection plates are symmetrically arranged front and back. The ecological holes are evenly and penetratingly arranged on the opposite sides of the slope protection plates. The push rods and the installation cross bars are both located on the opposite sides of the slope protection plates, and the installation cross bar is located on the opposite sides of the two push rods. The connecting rods are located on the opposite sides of the two installation cross bars and are symmetrically arranged left and right. The floating plates are located at the bottoms of the two groups of connecting rods. An installation groove is formed at the top of the slope protection plate. The control component is located in the inner cavity of the installation groove and is connected to the push rod;

[0008] When the floating plate moves upward, it drives the connecting rod, the installation cross bar and the push rod to move upward. The control component moves upward synchronously with the push rod and regulates the size of the ecological holes in the liquid surface below the floating plate.

[0009] In the above solution, for the current slope protection methods, although laying stones for slope protection has good structural stability, it is difficult to guarantee the ecological balance of the river course. The net surface interception for slope protection will cause a certain amount of soil erosion on the underwater slope surface. Especially for the areas of curved river courses, due to the water flow impact force suffered by the concave bank, it is more prone to soil erosion. This solution takes the horizontal plane as the boundary, regulates and protects the area below the water surface, and ensures the ecological balance of the area above the water surface, so as to avoid soil erosion and ensure the ecological balance of the slope bank at the same time.

[0010] Preferably, the control component includes control sheets, ventilation holes, liquid level display rods, rotating rods, transmission wheels and transmission belts. The rotating rods are symmetrically arranged up and down. The transmission wheels are located at the left and right ends of the rotating rods. The transmission belt is sleeved on the outer walls of the two longitudinal transmission wheels. The control sheet is wound around the outer wall of the bottom rotating rod. The innermost circle is connected to the rotating rod, and the outermost circle is connected to the front side of the transmission belt. The ventilation holes are opened on the outer wall of the control sheet, and the positions correspond to the ecological holes. The liquid level display rod is located at the top of the control sheet.

[0011] In the above solution, when the floating plate floats upward, it drives the installation cross bar and the push rod to move upward, thereby driving the transmission belt to move upward. Thus, the control sheet can be pulled upward to regulate the size of the ecological holes underwater. When the control sheet moves upward, it can drive the liquid level display rod to move upward synchronously, thereby realizing the monitoring and display of the water surface liquid level.

[0012] Preferably, protective rings are symmetrically arranged front and back on the inner circle of the ecological hole. The opposite sides of the protective rings are obliquely arranged, and the oblique angle of the front protective ring is the same as the inclination angle of the slope protection plate.

[0013] In the above solution, the hollow ecological holes can be protected by the protective rings. Setting the oblique angle of the front protective ring to be the same as the inclination angle of the slope protection plate can make the mud blocks or other impurities roll down along the inclination angle with inertia and gravity when passing through the ecological holes above the water surface, preventing them from staying at the openings of the ecological holes and thus affecting subsequent regulation.

[0014] Preferably, the distance between the two protective rings is less than the thickness of the regulating piece. The top of the regulating piece is provided with a sharp angle, and the inclination angle of the rear protective ring is set at a right angle to the inclination angle of the slope protection plate.

[0015] In the above solution, the distance between the protective rings being less than the thickness of the regulating piece can prevent excessive large impurities from entering the inner cavity of the slope protection plate. The sharp angle setting makes it easier for the regulating piece to move upward and push open the two protective rings. Setting the inclination angle of the rear protective ring at a right angle to the inclination angle of the slope protection plate can, on the one hand, scrape the mud adsorbed on the regulating piece, and on the other hand, observe the trend of soil erosion after regulation through the volume of the mud accumulated on the top of the rear protective ring to strengthen the protection in advance.

[0016] Preferably, a fixing block is connected to the front side of the transmission belt. A chute is opened on the surface of the slope protection plate. The fixing block is located inside the chute, and the rear side of the push rod is connected to the fixing block. The connecting rod is located at the center line position of two adjacent chutes.

[0017] In the above solution, the setting of the connecting rod at the center line position of two adjacent chutes can ensure that the thrust exerted on the push rod is more balanced, thereby avoiding the left - right height difference caused by unbalanced thrust during the rise of the regulating piece and thus preventing jamming.

[0018] Preferably, two groups of connecting rods are connected to a hinge rod on the laterally opposite sides. A symmetric center groove is opened at the horizontal center of the top of the floating plate, and the bottom of the hinge point of the hinge rod is located inside the center groove.

[0019] In the above solution, the hinge point of the hinge rod is slidably connected and limited to the center line position of the floating plate. The triangle formed by the hinge point and the connection points of the two connecting rods with the floating plate makes the force more balanced, thus avoiding the imbalance of the floating plate caused by the spacing deviation and affecting the subsequent floating.

[0020] Preferably, the floating plate is oval, and the major axis of the floating plate corresponds to the water flow direction.

[0021] In the above solution, the oval - shaped floating plate can buffer the water flow at the bend of the river channel, thereby reducing the pressure on the turning slope bank, reducing the possibility of soil erosion and deformation of the turning slope bank, and compared with a circular or minor - axis floating plate, buffering with the major axis can prevent the floating plate from moving due to water flow and thus being deformed and damaged.

[0022] Preferably, the bottom of the slope protection plate is provided with symmetrically arranged mounting rods on the left and right. A cylinder is sleeved on the opposite sides of the two mounting rods. A bottom fixing plate is arranged on the front side of the cylinder. Uniformly distributed fixing holes are formed in the top of the bottom fixing plate. Uniformly distributed fixing insertion rods are arranged on the opposite sides of the two slope protection plates.

[0023] In the above solution, the rotatable setting with the fixing plate enables the slope protection plate to be installed in cooperation with slopes of different gradients, and the fixing insertion rods can also adjust the insertion and fixing angles according to the actual installation angles, which is more convenient.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By dividing the slope surface into an above-water part and an underwater part, the present invention controls the part of the underwater slope surface where soil erosion is likely to occur, and does not change the part above water that needs to maintain ecological balance. Therefore, during the flood season or when the water level rises, the slope surface underwater (especially at the concave bank of the bent river channel) can be protected to avoid excessive soil erosion causing slope collapse, and the ecological balance of the exposed part of the slope bank after the flood season or when the water level drops is ensured.

[0026] 2. When the control piece moves upward, the present invention can drive the liquid level display rod to move upward, so as to synchronously monitor and display the liquid level. When the liquid level drops, the rear protection ring can scrape the slope soil adsorbed on the rear side of the downward-moving control piece. At the same time, the scraped soil accumulates on the top of the rear protection ring, and the amount of soil erosion data can be predicted by observing the amount of scraped soil, so as to achieve the monitoring and prediction of slope soil erosion.

[0027] 3. By setting an oval floating plate and installing it at the water flow direction of the bent river channel, the present invention can buffer the turning water flow to avoid it directly flowing to the concave bank of the bent river channel, thereby reducing the pressure on the slope surface of the bent river channel and reducing the possibility of slope soil erosion and deformation.

Specific implementation manners

[0038] The following is carried out in conjunction with the drawings in the embodiments of the present invention, and the technical solutions in the embodiments of the present invention are described more clearly and completely. The described embodiments are only a part of all the embodiments of the present invention. Based on the embodiments of the present invention, all embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] Please refer to Figures 1 to 8 , the present invention provides a liquid level and slope protection monitoring device for water conservancy projects, and the technical solutions are as follows:

[0040] A liquid level and slope protection monitoring device for water conservancy projects, including a slope protection plate 100, ecological holes 101, push rods 104, installation cross bars 105, connecting rods 112 and floating plates 113, and further including a regulation component. The slope protection plates 100 are symmetrically arranged front and back. The ecological holes 101 are evenly and penetratingly opened on the opposite sides of the slope protection plates 100. The push rods 104 and the installation cross bars 105 are both located on the opposite sides of the slope protection plates 100, and the installation cross bars 105 are fixedly connected to the opposite sides of the two push rods 104. The connecting rods 112 are rotatably connected (the rotation angle here is limited to 15 - 20°, so that the connecting rods 112 can not only adapt to the rotational adjustment after floating, but also prevent excessive rotation from causing displacement of the push rods 104 and the installation cross bars 105) to the opposite sides of the two installation cross bars 105 and are symmetrically arranged left and right. The floating plates 113 are located at the bottoms of the two groups of connecting rods 112, and the floating plates 113 are slidably connected to the two connecting rods 112 to adapt to river surfaces of different widths. An installation groove 102 is opened at the top of the slope protection plate 100 (during actual installation, the top of the installation groove 102 needs to be closed). The regulation component is located in the inner cavity of the installation groove 102 and is connected to the push rod 104;

[0041] When the floating plate 113 moves upward, it drives the connecting rod 112, the installation cross bar 105 and the push rod 104 to move upward. The regulation component moves upward synchronously with the push rod 104 and regulates the size of the ecological holes 101 in the liquid level below the floating plate 113. Thus, the size of the ecological holes 101 underwater can be regulated to avoid soil and water loss, while the ecological holes 101 above the water surface remain unchanged to ensure ecological balance.

[0042] As an implementation manner of the present invention, referring to Figures 2 to 4 , the regulation component includes a regulation piece 106, air holes 107, a liquid level display rod 108, a rotating rod 116, a transmission wheel 117 and a transmission belt 118. The rotating rods 116 are symmetrically arranged up and down. The transmission wheels 117 are located at the left and right ends of the rotating rod 116, and the transmission belt 118 is sleeved on the outer walls of the two longitudinal transmission wheels 117. The regulation piece 106 is wound around the outer wall of the bottom rotating rod 116, and the innermost circle is connected to the rotating rod 116, and the outermost circle is connected to the front side of the transmission belt 118. The air holes 107 are opened on the outer wall of the regulation piece 106, and the positions correspond to the ecological holes 101. The liquid level display rod 108 is located at the top of the regulation piece 106. When the floating plate 113 moves upward, it drives the connecting rod 112, the installation cross bar 105 and the push rod 104 to move upward. Thus, the transmission belt 118 connected to the push rod 104 moves upward for upward transmission, thereby driving the regulation piece 106 to move upward accordingly and closing the ecological holes 101 below the water surface. At the same time, the air holes 107 are provided to ensure the pressure difference. And when the regulation piece 106 moves upward, it can drive the liquid level display rod 108 to move upward. Therefore, the monitoring and display of the liquid level are also synchronized.

[0043] As an implementation manner of the present invention, referring to Figure 1, a protective ring 115 is symmetrically arranged before and after inside the inner circle of the ecological hole 101. The opposite sides of the protective ring 115 are obliquely arranged, and the oblique angle of the front protective ring 115 is the same as the inclination angle of the slope protection plate 100. The protective ring 115 is used to protect the hollow ecological hole 101. Setting the oblique angle of the front protective ring 115 to be the same as the oblique angle of the slope protection plate 100 allows mud blocks or other impurities passing through the ecological hole 101 to either roll down along the inclination angle or enter the slope surface along the inclination angle, preventing them from staying at the opening of the ecological hole 101 and causing blockage, thus affecting subsequent regulation. The distance between the two protective rings 115 is less than the thickness of the regulation piece 106. The top of the regulation piece 106 is provided with a sharp angle. The inclination angle of the rear protective ring 115 is set at a right angle to the inclination angle of the slope protection plate 100. When the distance between the two protective rings 115 is less than the thickness of the regulation piece 106 and the regulation piece 106 extends out after regulation, the protective ring 115 closely adheres to the regulation piece 106, thereby straightening the regulation piece 106 and improving its ability to withstand water flow impact. The sharp angle at the top of the regulation piece 106 enables it to quickly push open the two protective rings 115 when rising, thus completing the upward regulation. And the rear protective ring 115 being set at a right angle to the slope protection plate 100 can scrape the slope soil adsorbed on the rear side of the downward moving regulation piece 106. At the same time, the scraped soil accumulates on the top of the rear protective ring 115, and the amount of soil erosion data can be predicted by observing the amount of scraped soil, so as to achieve the monitoring and prediction of slope soil erosion.

[0044] As an implementation manner of the present invention, referring to Figures 5 to 6 , a fixing block 119 is fixedly connected to the front side of the transmission belt 118. A sliding groove 103 is opened on the surface of the slope protection plate 100. The fixing block 119 is located inside the inner cavity of the sliding groove 103. The rear side of the push rod 104 is fixedly connected to the fixing block 119. By moving the push rod 104 upward, the fixing block 119 is driven to move upward, thereby driving the fixedly connected transmission belt 118 to move upward accordingly, so as to complete the regulation of the ecological hole 101. The connecting rod 112 is located at the center line position of two adjacent sliding grooves 103. This setting can make the thrust applied to the push rod 104 more balanced, thereby avoiding the left-right height difference generated after the regulation piece 106 rises due to unbalanced thrust, thus causing a jamming phenomenon. Two groups of connecting rods 112 are connected to the lateral opposite sides with a hinge rod 114. A symmetric center groove 121 is opened on the horizontal center of the top of the floating plate 113. The bottom of the hinge point of the hinge rod 114 is located inside the inner cavity of the center groove 121. Through the sliding of the hinge rod 114 and the center groove 121, a triangle is formed by the hinge point and the connection points of the two connecting rods 112 and the floating plate 113, thus ensuring the stability of the connection and preventing the floating plate 113 from being unbalanced due to deviation at one end, thereby affecting subsequent floating.

[0045] As an implementation manner of the present invention, referring to Figure 7, the floating board 113 is oval, and the major axis of the floating board 113 corresponds to the water flow direction. Compared with a circular shape, the oval floating board 113 has a smaller water flow contact area in the major axis direction, and can buffer the water flow at the bent river channel, avoiding direct impact on the river bank, thereby reducing the pressure on the slope of the bent river channel and reducing the possibility of soil erosion and deformation on the slope.

[0046] As an implementation manner of the present invention, refer to Figure 1 , the bottom of the slope protection board 100 is fixedly connected with symmetrically arranged mounting rods 110 on the left and right. A cylinder 122 is sleeved on the opposite sides of the two mounting rods 110. The front side of the cylinder 122 is fixedly connected with a bottom fixing plate 109. Uniformly distributed fixing holes 111 are opened on the top of the bottom fixing plate 109. The bottom fixing plate 109 can be fixed by inserting a fixing rod into the fixing hole 111, and the slope protection board 100 can be rotationally adjusted with the cylinder 122 as the center according to the actual slope angle, so as to adapt to slopes of different angles. Uniformly distributed fixing insertion rods 120 are arranged on the opposite sides of the two slope protection boards 100. After the rotational adjustment is completed, the fixing insertion rods 120 on the back of the slope protection board 100 can be adjusted to be parallel to the top of the slope and then inserted into the slope inclined surface to complete the fixing of the slope protection board 100.

[0047] Working principle: In this solution, the slope is divided into an upper part and a lower part in the water. The part of the lower part in the water where soil erosion is likely to occur is regulated, while the part of the upper part in the water that needs to maintain ecological balance is not changed, so as to achieve the slope protection effect. At the same time, during the slope protection process, the monitoring of the liquid level and the prediction of soil erosion on the slope can be completed. The specific process is as follows:

[0048] Installation: When installing the equipment of this solution, its installation position is at the bent river channel and corresponds to the river flow direction (as shown in Figure 8 ), insert the fixing rod into the fixing hole 111 and insert it into the bottom of the river channel to fix the bottom fixing plate 109. The slope protection board 100 can be rotationally adjusted with the cylinder 122 as the center according to the actual slope angle, so as to adapt to slopes of different angles. After the rotational adjustment is completed, the fixing insertion rods 120 on the back of the slope protection board 100 can be adjusted to be parallel to the top of the slope and then inserted into the slope inclined surface to complete the installation and fixing of the slope protection board 100;

[0049] Adjustable protection: After the river water enters the water flow, the floating board 113 will float with the water flow, which can drive the connecting rod 112 to move upward synchronously. As the connecting rod 112 moves upward, it can drive the mounting cross bar 105 and the push rod 104 to move upward. When the push rod 104 moves upward, the fixed block 119 fixedly connected to it also moves upward, thereby driving the transmission belt 118 fixedly connected to it to move upward. Therefore, the regulation piece 106 connected to the outermost circle of the transmission belt 118 can be driven to rise. After the regulation piece 106 rises, it closes the ecological holes 101, and the ventilation holes 107 corresponding to the ecological holes 101 ensure the balance of the pressure difference on both sides of the slope protection. The closed ecological holes 101 underwater can effectively prevent soil and water loss.

[0050] Liquid level and slope protection monitoring: When the regulation piece 106 moves upward, it can drive the liquid level display rod 108 to move upward, so as to synchronously monitor and display the liquid level. The extended part of the liquid level display rod 108 is proportional to the liquid level and the inclination angle of the slope protection board 100. When the liquid level drops, the floating board 113 also drops, which drives the regulation piece 106 to move downward. The rear protection ring 115 can scrape off the slope soil adsorbed on the rear side of the downward moving regulation piece 106. At the same time, the scraped soil accumulates on the top of the rear protection ring 115. By observing the amount of scraped soil, the soil and water loss data can be predicted, so as to monitor and predict the soil and water loss on the slope surface.

[0051] The main advantages and working principles of the embodiments of the present invention have been described above. However, as a person skilled in the art, it should be understood that the above embodiments are not restrictive conditions of the present invention. Without departing from the principles, spirit and scope of the invention, various changes, modifications, substitutions and variations can be made, and all these changes, modifications, substitutions and variations should fall within the protection scope of the present invention.
