Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering, and in particular to a sidewall support device for water conservancy engineering construction. Background Technology

[0002] Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production. Water conservancy projects typically involve digging canals to achieve their objectives.

[0003] However, since the channels are excavated and the channel sidewalls generally have a certain degree of inclination, it is necessary to support the channel sidewalls in order to reduce earthwork collapse. Currently, most of the existing channel sidewall support devices are not easy to install and remove. Multiple workers are required to work together to install the support devices on the inner wall of the channel. When the support is no longer needed, it is also quite troublesome to remove the support devices from the inner wall of the channel. In addition, the existing devices support the channel sidewalls in a relatively simple way and the supporting force is relatively small, which makes it difficult to stably support the channel sidewalls. Summary of the Invention

[0004] In view of this, the present invention provides a sidewall support device for water conservancy engineering construction that is easy to install and remove, and allows the pressure plate and resistance rod to make closer contact with the sidewall of the water conservancy channel, thereby providing more stable support for the inclined sidewall of the water conservancy channel.

[0005] Technical solution: A sidewall support device for water conservancy engineering construction includes a housing, a slide rail, a baffle, an electric slider, a pressing mechanism, and a resistance mechanism. The slide rail is fixedly connected inside the housing, and the baffle is fixedly connected to the upper part of the slide rail. The electric slider is slidably connected to the slide rail, and the electric slider has a slot. The pressing mechanism is disposed on the housing, and the resistance mechanism is disposed on the pressing mechanism and connected to the electric slider.

[0006] In a preferred embodiment of the present invention, the clamping mechanism includes a supporting slider, a buffer spring, a rotating rod, a fixed shaft, and a pressure plate. The supporting slider is slidably connected to the slide rail, and a buffer spring is connected between the supporting slider and the electric slider. The rotating rod is rotatably connected to the supporting slider, and the rotating rod has two symmetrically arranged locking slots. The fixed shaft is fixedly connected to the housing, and the pressure plate is rotatably connected to the fixed shaft. The rotating rod is rotatably connected to the pressure plate.

[0007] In a preferred embodiment of the present invention, the resistance mechanism includes a rack, a rotating shaft, a rotating gear, and resistance rods. The rack is fixedly connected to the electric slider, the rotating shaft is rotatably connected to the support slider, the rotating gear is fixedly connected to the rotating shaft, the rack meshes with the rotating gear, and two resistance rods are fixedly connected to the rotating shaft, the two resistance rods being symmetrically arranged.

[0008] In a preferred embodiment of the present invention, a locking mechanism is further included. The locking mechanism is disposed on the rotating shaft and connected to the support slider. The locking mechanism includes a cam, a sliding rod, and a return spring. Two cams are fixedly connected to the rotating shaft and are symmetrically arranged. Two sliding rods are slidably connected to the support slider and are symmetrically arranged. A return spring is connected between each of the two sliding rods and the support slider.

[0009] In a preferred embodiment of the present invention, a fastening mechanism is further included. The fastening mechanism is disposed on the housing and includes a rack and pinion, a gear shaft, a synchronizing gear, and a pusher cone plate. Two rack and pinion are fixedly connected to the support slider and are symmetrically arranged. Two gear shafts are rotatably connected to the housing and are symmetrically arranged. Two synchronizing gears are fixedly connected to each of the two gear shafts. The two rack and pinion are respectively engaged with one of the synchronizing gears on the two gear shafts. The two synchronizing gears on each gear shaft are symmetrically arranged. Two pusher cone plates are slidably connected to the housing and are symmetrically arranged.

[0010] In a preferred embodiment of the present invention, a locking rod and an assist spring are further included. The locking rod is slidably connected to the housing, and the locking rod has an inclined surface. An assist spring is connected between the locking rod and the housing.

[0011] In a preferred embodiment of the present invention, an anti-slip plate is also included, and an anti-slip plate is fixedly connected to both of the resistance rods.

[0012] In a preferred embodiment of the present invention, the housing is provided with four inclined support rods, which enable the housing to be placed more stably on the ground.

[0013] In a preferred embodiment of the present invention, both rack links are composed of a bent rod and a short rack fixedly connected to the bent rod.

[0014] In a preferred embodiment of the present invention, each of the two pushing cone plates consists of a sliding plate and two cone rods fixedly connected to the bottom of the sliding plate.

[0015] In a preferred embodiment of the present invention, both anti-slip plates are made of rubber.

[0016] Compared with existing technologies, this invention has the following advantages: First, the operator places the device in the irrigation canal requiring stability, then activates the electric slider. The electric slider causes the pressure plate and resistance rod to move upwards and away from the slide rail. As the electric slider continues to move upwards, it compresses the buffer spring, causing the buffer spring to exert an upward force on the supporting slider. This makes the pressure plate and resistance rod more tightly contact the side wall of the canal, thus providing stable support for the inclined side wall of the irrigation canal. After use, the operator adjusts the electric slider. The resistance rod moves downwards to reset and is then held in place by the housing. The rotating rod moves downwards to reset and pulls the pressure plate to swing back towards the slide rail. Then, the operator pulls the device upwards to remove it from the ground. Thus, it not only provides stable support for the inclined side wall of the irrigation canal but is also easy to install and remove, making it highly practical.

[0017] Second, the rotation of the rotating shaft will drive the cam to rotate. When the cam's convex surface rotates to contact the sliding rod, the cam will push against the sliding rod and move towards the rotating rod. The sliding rod will move towards the rotating rod and get into the locking groove on the rotating rod. At the same time, the cam's convex surface will always push against the sliding rod, which can reduce the possibility of the pressure plate and resistance rod swinging due to external forces, thereby improving the support effect of the pressure plate and resistance rod on the side wall of the water conservancy channel.

[0018] Third, the upward movement of the supporting slider will drive the rack and pinion to move upward. The upward movement of the rack and pinion will drive one of the synchronous gears to rotate. The rotation of the synchronous gear will drive the gear shaft to rotate. The rotation of the gear shaft will drive the other synchronous gear to rotate. The rotation of the other synchronous gear will cause the push cone plate to move downward. The downward movement of the push cone plate will lock into the ground, so that the device can be stably fixed in the water conservancy channel that requires stability, thereby providing more stable support for the inclined side wall of the water conservancy channel.

[0026] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0027] Example 1: A sidewall support device for water conservancy engineering construction, such as Figures 1-5 As shown, the device includes a housing 1, a slide rail 101, a baffle 103, an electric slider 102, a pressing mechanism, and a resistance mechanism. The slide rail 101 is bolted inside the housing 1. The housing 1 has four inclined support rods, which allow the housing 1 to be placed more stably on the ground. The baffle 103 is bolted to the upper part of the slide rail 101. The electric slider 102 is slidably connected to the slide rail 101. The electric slider 102 has a slot. The pressing mechanism is set on the housing 1. The resistance mechanism is set on the pressing mechanism and is connected to the electric slider 102.

[0028] The clamping mechanism includes a support slider 23, a buffer spring 24, a rotating rod 25, a fixed shaft 26, and a pressure plate 27. The support slider 23 is slidably connected to the slide rail 101. The buffer spring 24 is connected to the support slider 23 and the electric slider 102 via a hook. The rotating rod 25 is rotatably connected to the support slider 23. The rotating rod 25 has two locking slots, which are symmetrically arranged. The fixed shaft 26 is bolted to the housing 1. The pressure plate 27 is rotatably connected to the fixed shaft 26. The rotating rod 25 and the pressure plate 27 are rotatably connected.

[0029] The resistance mechanism includes a rack 31, a rotating shaft 32, a rotating gear 33, and resistance rods 34. The rack 31 is bolted to the electric slider 102, and the rotating shaft 32 is rotatably connected to the support slider 23. The rotating gear 33 is connected to the rotating shaft 32 via a flat key. The rack 31 meshes with the rotating gear 33. Two resistance rods 34 are riveted to the rotating shaft 32, and the two resistance rods 34 are symmetrically arranged.

[0030] Initially, housing 1 abuts against resistance rod 34, which in turn abuts against rotating shaft 32 and rotating gear 33. During use, the operator places the device in a stable irrigation canal. Then, the operator activates electric slider 102, which moves upwards. This upward movement of electric slider 102 drives rack 31 upwards. Because resistance rod 34 abuts against rotating shaft 32 and rotating gear 33, the upward movement of rack 31 does not cause rotating gear 33 to rotate. Instead, the upward movement of rack 31 pushes rotating gear 33 upwards, which in turn drives rotating shaft 32 upwards. The upward movement of rotating shaft 32 then drives support slider 23 and resistance rod 34 upwards. The upward movement of support slider 23 then drives... The rotating rod 25 moves upward, pushing the pressure plate 27 to swing away from the slide rail 101. When the supporting slider 23 moves upward and contacts the baffle 103, the baffle 103 will abut against the supporting slider 23. The resistance rod 34 just moves out of the housing 1, and the housing 1 no longer abuts against the resistance rod 34. The pressure plate 27 swings away from the slide rail 101 and contacts the channel side wall. The electric slider 102 continues to move upward, squeezing the buffer spring 24 and driving the rack rod 31 to continue moving upward. The rack rod 31 continues to move upward, causing the rotating gear 33 to rotate. The rotation of the rotating gear 33 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the resistance rod 34 to swing away from the slide rail 101. The directional swing of 01 will also contact the channel sidewall. Simultaneously, the compressed buffer spring 24 will again exert an upward force on the support slider 23, thus making the pressure plate 27 and resistance rod 34 contact the channel sidewall more tightly, thereby stably supporting the inclined sidewall of the water conservancy channel. After use, the operator adjusts the electric slider 102. The electric slider 102 will move downwards and will no longer compress the buffer spring 24, causing the buffer spring 24 to reset. The downward movement of the electric slider 102 will drive the rack rod 31 to move downwards and reset. The downward movement of the rack rod 31 will drive the rotating gear 33 to rotate in the opposite direction and reset. The reverse rotation of the rotating gear 33 will drive the rotating shaft 32 to rotate in the opposite direction and reset. The reverse rotation of the rotating shaft 32 will drive the resistance rod 34... The device swings towards the slide rail 101 to reset. The electric slider 102 continues to move downwards, causing the rack 31 to continue moving downwards to reset. The rack 31's downward movement further resets the rotating gear 33, rotating shaft 32, and resistance rod 34 to move downwards to reset. The resistance rod 34, after resetting, is again held in place by the housing 1. The rotating shaft 32's downward movement resets the support slider 23, which in turn resets the rotating rod 25. The rotating rod 25's downward movement resets the pressure plate 27, causing it to swing towards the slide rail 101 to reset. Then, the operator pulls the device upwards, preventing it from getting stuck in the ground and removing it. This not only provides stable support for the inclined sidewalls of the irrigation canal but also...It is also easy to install and remove, making it highly practical.

[0031] Example 2: Based on Example 1, such as Figure 4 and Figure 5 As shown, it also includes a locking mechanism, which is mounted on the rotating shaft 32 and connected to the support slider 23. The locking mechanism includes a cam 41, a sliding rod 42, and a return spring 43. Two cams 41 are bolted to the rotating shaft 32 and are symmetrically arranged. Two sliding rods 42 are slidably connected to the support slider 23 and are symmetrically arranged. Each sliding rod 42 is connected to the support slider 23 by a return spring 43 via a hook.

[0032] The rotation of the rotating shaft 32 will drive the cam 41 to rotate. When the convex surface of the cam 41 rotates to contact the sliding rod 42, the cam 41 will push against the sliding rod 42 and move towards the rotating rod 25. The return spring 43 will be stretched. The sliding rod 42 will move towards the rotating rod 25 and get into the locking groove on the rotating rod 25. At the same time, the convex surface of the cam 41 will always push against the sliding rod 42, which can reduce the possibility of the pressure plate 27 and the resistance rod 34 swinging under the influence of external forces, thereby improving the support effect of the pressure plate 27 and the resistance rod 34 on the side wall of the water conservancy channel. The reverse rotation of the rotating shaft 32 will drive the cam 41 to rotate in the opposite direction. The reverse rotation of the cam 41 will cause the convex surface of the cam 41 to disengage from the sliding rod 42. The return spring 43 will return to its original position. The return spring 43 returning to its original position will drive the sliding rod 42 to return to its original position.

[0033] Example 3: Based on Example 2, such as Figures 1-3 and Figure 6 As shown, it also includes a fastening mechanism, which is mounted on the housing 1. The fastening mechanism includes a rack and pinion 51, a gear shaft 52, a synchronizing gear 53, and a pusher cone plate 54. Two rack and pinion 51 are bolted to the support slider 23. Each rack and pinion 51 consists of a bent rod and a short rack fixedly connected to the bent rod. The two rack and pinion 51 are symmetrically arranged. Two gear shafts 52 are rotatably connected to the housing 1. The two gear shafts 52 are symmetrically arranged. Two synchronizing gears 53 are connected to each gear shaft 52 via a flat key. Each rack and pinion 51 meshes with one of the synchronizing gears 53 on each gear shaft 52. The two synchronizing gears 53 on each gear shaft 52 are symmetrically arranged. Two pusher cone plates 54 are slidably connected to the housing 1. Each pusher cone plate 54 consists of a sliding plate and two cone rods fixedly connected to the bottom of the sliding plate. The two pusher cone plates 54 are symmetrically arranged.

[0034] The upward movement of the support slider 23 causes the rack and pinion 51 to move upward. The upward movement of the rack and pinion 51 causes one of the synchronous gears 53 to rotate. The rotation of the synchronous gear 53 causes the gear shaft 52 to rotate. The rotation of the gear shaft 52 causes the other synchronous gear 53 to rotate. The rotation of the other synchronous gear 53 causes the push cone plate 54 to move downward. The downward movement of the push cone plate 54 will cause it to engage with the ground, allowing the device to be stably fixed within the water conservancy channel that requires stability. This provides more stable support for the inclined sidewalls of the water conservancy channel. When the support slider 23 moves downward to reset, it causes the rack and pinion 51 to move downward to reset. The downward movement of the rack and pinion 51 will cause one of the synchronous gears 53 to rotate in the opposite direction. The reverse rotation of the synchronous gear 53 will cause the gear shaft 52 to rotate in the opposite direction. The reverse rotation of the gear shaft 52 will cause the other synchronous gear 53 to rotate in the opposite direction. The reverse rotation of the other synchronous gear 53 will cause the push cone plate 54 to move upward to reset, preventing the push cone plate 54 from engaging with the ground.

[0035] Example 4: Based on Example 3, such as Figure 2 and Figure 3 As shown, it also includes a locking rod 61 and a booster spring 62. The locking rod 61 is slidably connected to the housing 1. The locking rod 61 is provided with an inclined surface. The booster spring 62 is connected to the locking rod 61 and the housing 1 through a hook.

[0036] When the electric slider 102 moves upward, it will contact the locking rod 61. When the electric slider 102 moves upward and contacts the locking rod 61, the electric slider 102 will push the locking rod 61 along the inclined surface of the locking rod 61 to move away from the pressure plate 27. The assist spring 62 will be stretched. When the electric slider 102 moves upward and the slot on the electric slider 102 is at the same level as the locking rod 61, the assist spring 62 will reset. The reset of the assist spring 62 will drive the locking rod 61 to be locked into the slot on the electric slider 102, thereby further reducing the possibility of the pressure plate 27 and the resistance rod 34 swinging due to external forces, thereby further improving the support effect of the pressure plate 27 and the resistance rod 34 on the side wall of the water conservancy channel. After use, the staff will pull the locking rod 61 away from the slide rail 101, and the assist spring 62 will be stretched, so that the locking rod 61 is no longer locked in the slot on the electric slider 102.

[0037] Example 5: Based on Example 4, such as Figures 2-4 As shown, it also includes anti-slip plates 71. Both of the resistance rods 34 are connected to the anti-slip plates 71 by bolts. Both anti-slip plates 71 are made of rubber.

[0038] The anti-slip plate 71 can increase the friction between the resistance bar 34 and the ground, thereby enabling the resistance bar 34 to provide more stable support to the side wall of the canal.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
