Description

Technical Field

[0001] The utility model belongs to the technical field of river channel protection, and in particular relates to a downstream river channel protection device for water conservancy projects. Background Art

[0002] In water conservancy projects, the main reason why downstream river channels need protection is to prevent river water from eroding the downstream riverbed and bank slopes, causing flood disasters and ecological environmental damage. Building stable river embankments in downstream river channels can play a big role, but when encountering heavy rains, the downstream river channels are usually located at the outlet of a catchment area, which is the drainage outlet for large tracts of land nearby. When the rainfall in the catchment area exceeds the carrying capacity of the river channel, the river flow increases. If the protection measures for the river embankment are not complete, overflow is likely to occur. The staff will use protective devices on the river embankments of the downstream river channels for protection as soon as possible.

[0003] Existing protective devices are usually large in size, making them difficult to store and transport. In addition, the devices will be impacted by water flow when in use. The rapid water flow will produce a large impact force on the protective devices, which can easily cause damage to the protective devices, reduce their service life and affect the protective effect.

[0004] Therefore, there is a need for a downstream river protection device for water conservancy projects to solve the problems in the prior art that the protection device is difficult to fold, occupies a lot of space, and is easily damaged after being impacted by water flow. Utility Model Content

[0005] The purpose of the utility model is to provide a downstream river protection device for water conservancy projects to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a downstream river protection device for water conservancy projects, comprising a base, fixing holes are opened through the four corners of the top surface of the base, a slot hole is opened at the center of the top surface of the base, a U-shaped seat is fixedly connected to one side of the top surface of the base, an anti-skid plate is fixedly connected to the bottom surface of the base, a rotating shaft is rotatably connected between the inner walls at both ends of the recess of the U-shaped seat, a baffle is fixedly mounted on the outer surface of the rotating shaft, a folding mechanism is arranged on the base, and a buffer mechanism is arranged on the outer wall of one side of the baffle.

[0007] It should be noted in the scheme that the folding mechanism includes a motor fixedly connected to the center of the outer wall on one side of the base, the output end of the motor rotates through the outer wall on one side of the base and extends into the slot, the output end of the motor is coaxially fixedly connected with a threaded rod, the end of the threaded rod away from the motor is rotatably connected to the inner wall on one side of the slot, the outer surface of the threaded rod is threadedly connected with a threaded sleeve, the top surface of the threaded sleeve is fixedly connected with a first hinge seat, a connecting rod is hinged in the first hinge seat, the other end of the connecting rod is hinged with a second hinge seat, and the outer wall of one side of the second hinge seat is fixedly connected to the center of the outer wall of one side of the baffle.

[0008] It is further worth explaining that the buffer mechanism includes a buffer plate, a plurality of parallel distributed buffer belts are fixedly connected to the outer wall on one side of the buffer plate, two parallel distributed first limit sleeves are fixedly connected to the inner wall on the other side of the buffer plate, a rotating rod is rotatably connected inside the first limit sleeve, both ends of the rotating rod are rotatably connected to second limit sleeves, and a slider is fixedly connected to the outer wall on one side of each of the second limit sleeves.

[0009] It should be further explained that the buffer mechanism also includes four slide grooves respectively matched with four sliders, the slide grooves are opened on the outer wall of one side of the baffle, and a guide rod is fixedly connected between the top surface and the bottom surface of the slide groove. The guide rod slides through the slider, and a spring is sleeved on the outer surface of the guide rod. One end of the spring is fixedly connected to the top surface of the slider, and the other end of the spring is fixedly connected to the top surface of the slide groove.

[0010] As a preferred embodiment, the four fixing holes all penetrate the anti-slip plate, the outer surface of the threaded sleeve is slidably connected to the inner wall of the slot, and the inner wall of one side of the buffer plate is equal in size to the baffle.

[0011] As a preferred implementation, the buffer belt is configured as a wave-shaped structure, and the two springs that match the same rotating rod are symmetrically distributed.

[0012] Compared with the prior art, the downstream river protection device for water conservancy projects provided by the utility model has at least the following beneficial effects:

[0013] (1) Through the adjustment of the folding mechanism, the motor drives the threaded rod to rotate, and then the threaded sleeve pushes the connecting rod to move. Under the action of the hinge, the connecting rod pushes the baffle to rotate around the axis of the rotating shaft, so that the baffle can be folded and unfolded to block the water flow in the river. The operation is simple and easy to use, and the problem that the protective device is difficult to fold and occupies more space is effectively avoided.

[0014] (2) Through the action of the buffer mechanism, the buffer belt initially buffers the impact force of the water flow, and the buffer plate is forced to push the slider to slide in the slide groove.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] See also Figure 1-3 The utility model provides a downstream river protection device for water conservancy projects, including a base 1, fixing holes 2 are opened through the four corners of the top surface of the base 1, a slot hole 3 is opened at the center of the top surface of the base 1, a U-shaped seat 4 is fixedly connected to one side of the top surface of the base 1, an anti-skid plate 9 is fixedly connected to the bottom surface of the base 1, a rotating shaft 5 is rotatably connected between the inner walls at both ends of the concave part of the U-shaped seat 4, a baffle 6 is fixedly sleeved on the outer surface of the rotating shaft 5, a folding mechanism 7 is arranged on the base 1, and a buffer mechanism 8 is arranged on the outer wall of one side of the baffle 6.

[0021] Further Figure 2As shown, it is worth explaining in detail that the folding mechanism 7 includes a motor 71 fixedly connected to the center of the outer wall on one side of the base 1, the output end of the motor 71 rotates through the outer wall on one side of the base 1 and extends into the slot 3, the output end of the motor 71 is coaxially fixedly connected with a threaded rod 72, the end of the threaded rod 72 away from the motor 71 is rotatably connected to the inner wall on one side of the slot 3, the outer surface of the threaded rod 72 is threadedly connected with a threaded sleeve 73, the top surface of the threaded sleeve 73 is fixedly connected with a first hinge seat 74, the first hinge seat 74 is hinged with a connecting rod 75, the other end of the connecting rod 75 is hinged with a second hinge seat 76, and the outer wall of one side of the second hinge seat 76 is fixedly connected to the center of the outer wall on one side of the baffle 6.

[0022] Further as Figure 3 As shown, it is worth explaining in detail that the buffer mechanism 8 includes a buffer plate 81, and a plurality of parallel distributed buffer belts 82 are fixedly connected to the outer wall on one side of the buffer plate 81, and two parallel distributed first limit sleeves 83 are fixedly connected to the inner wall on the other side of the buffer plate 81, and a rotating rod 84 is rotatably connected inside the first limit sleeve 83, and both ends of the rotating rod 84 are rotatably connected to second limit sleeves 85, and a slider 86 is fixedly connected to the outer wall on one side of each second limit sleeve 85.

[0023] Further as Figure 3 As shown, it is worth explaining in detail that the buffer mechanism 8 also includes four slide grooves 87 respectively matched with the four sliders 86. The slide grooves 87 are opened on the outer wall of one side of the baffle 6. A guide rod 88 is fixedly connected between the top and bottom surfaces of the slide grooves 87. The guide rod 88 slides through the slider 86. A spring 89 is sleeved on the outer surface of the guide rod 88. One end of the spring 89 is fixedly connected to the top surface of the slider 86, and the other end of the spring 89 is fixedly connected to the top surface of the slide groove 87.

[0024] This solution has the following working process: when the protective device is in use, the device is first placed on the river bank of the target area, the base 1 is fixed through the four fixing holes 2, the anti-skid plate 9 improves the stability of the base 1, and then the motor 71 is turned on. The rotation of the motor 71 drives the threaded rod 72 to rotate. Under the action of the thread, the threaded sleeve 73 moves on the threaded rod 72. The threaded sleeve 73 pushes the connecting rod 75 while moving. At the same time, with the cooperation of the first articulated seat 74 and the second articulated seat 76, the connecting rod 75 pushes the baffle 6, so that the baffle 6 rotates around the axis of the rotating shaft 5 on the U-shaped seat 4, thereby realizing the folding and unfolding of the baffle 6, increasing the height of the river bank, and blocking the water flow in the river.

[0025] When the water flow in the river channel impacts the protective device, the water flow first impacts the buffer belt 82, and the buffer belt 82 performs preliminary buffering on the impact force of the water flow. When the buffer belt 82 is impacted, the buffer plate 81 is also impacted. After the impact, the buffer plate 81 moves and pushes the two sets of rotating rods 84. After the rotating rod 84 is subjected to force, it pushes the slider 86 to slide in the slide groove 87. Under the action of the spring 89, the impact force of the water flow is further buffered, thereby reducing the impact force of the water flow, making the device less likely to be damaged, and increasing the service life of the device.

[0026] According to the above working process, it can be known that: through the adjustment of the folding mechanism 7, the motor 71 drives the threaded rod 72 to rotate, and then the threaded sleeve 73 pushes the connecting rod 75 to move. Under the action of the hinge, the connecting rod 75 pushes the baffle 6 to rotate around the axis of the rotating shaft 5, so as to realize the folding and unfolding of the baffle 6, and block the water flow in the river channel. The operation is simple and easy to use, and the problem that the protective device is not easy to fold and occupies more space is effectively avoided.

[0027] Through the action of the buffer mechanism 8, the buffer belt 82 initially buffers the impact force of the water flow, and the buffer plate 81 is forced to push the slider 86 to slide in the slide groove 87. Under the action of the spring 89, the impact force of the water flow is further buffered, thereby reducing the impact force of the water flow. At the same time, the buffer plate 81 protects the baffle 6, making the device not easily damaged, effectively avoiding the problem that the protective device is easily damaged after being impacted by the water flow.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the four fixing holes 2 all penetrate the anti-slip plate 9, which is convenient for fixing the base 1 and the anti-slip plate 9. The outer surface of the threaded sleeve 73 is slidingly connected to the inner wall of the slot hole 3, which further improves the mobility of the threaded sleeve 73. The inner wall on one side of the buffer plate 81 is equal to the baffle 6 in size, which improves the force level of the buffer plate 81.

[0029] Further as Figure 3 As shown, it is worth explaining in detail that the buffer belt 82 is set to a wave-shaped structure, which can buffer the impact force of water flow. The two springs 89 that match each other on the same rotating rod 84 are symmetrically distributed, so that the spring 89 can buffer the impact force on the buffer plate 81.

[0030] In summary: when the protective device is in use, the device is first placed on the river bank of the target area, the base 1 is fixed through the four fixing holes 2, the anti-skid plate 9 improves the stability of the base 1, and then the motor 71 is turned on. The rotation of the motor 71 drives the threaded rod 72 to rotate. Under the action of the thread, the threaded sleeve 73 moves on the threaded rod 72, and the threaded sleeve 73 pushes the connecting rod 75 while moving. At the same time, with the cooperation of the first hinge seat 74 and the second hinge seat 76, the connecting rod 75 pushes the baffle 6, so that the baffle 6 rotates around the axis of the rotating shaft 5 on the U-shaped seat 4, thereby realizing the folding and unfolding of the baffle 6, increasing the height of the river bank, and blocking the water flow in the river channel, effectively avoiding the problem that the protective device is not easy to fold and occupies more space.

[0031] When the water flow in the river channel impacts the protective device, the water flow first impacts the buffer belt 82, and the buffer belt 82 performs preliminary buffering on the impact force of the water flow. When the buffer belt 82 is impacted, the buffer plate 81 is also impacted. After the impact, the buffer plate 81 is displaced and pushes the two sets of rotating rods 84. After the rotating rod 84 is subjected to force, it pushes the slider 86 to slide in the slide groove 87. Under the action of the spring 89, the impact force of the water flow is further buffered, which reduces the impact force of the water flow, makes the device less likely to be damaged, increases the service life of the device, and effectively avoids the problem that the protective device is easily damaged after being impacted by the water flow.

[0032] The motor 71 can be purchased on the market. The motor 71 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
