Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically a protective device for water conservancy construction. Background Technology

[0002] Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, and canals, to regulate and distribute water resources and meet the needs of people's lives and production. During the construction of water conservancy projects, various deep pits and ditches are typically excavated; therefore, protective devices must be installed near the construction sites to ensure construction safety.

[0003] Currently available protective devices are typically protective nets placed directly on the ground. To increase strength, individual nets are often connected into a single unit using bolts or other connecting structures. However, these nets have poor stability and are prone to tipping over when subjected to human impacts, strong winds, heavy rain, or other external factors. This is especially true in construction environments with soft soil, where the nets are more likely to collapse and fail to provide adequate protection. Furthermore, they waste space when not in use and are inconvenient to carry. Therefore, there is a need to develop an improved protective device for hydraulic construction to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for water conservancy construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for water conservancy construction, comprising a first vertical column and a second vertical column, wherein both the first vertical column and the second vertical column are provided with two extension mechanisms inside, and both the first vertical column and the second vertical column are provided with an installation mechanism at their bottoms.

[0006] Preferably, the extension mechanism includes a slider, which is slidably installed inside the first vertical column. Two sliders are slidably installed inside both the first and second vertical columns. A telescopic fence is provided between the two sets of sliders. A rotating column is rotatably installed inside the second vertical column. A rotating rod is fixedly installed on the front of the rotating column. A fixing frame is fixedly installed on the front of the rotating rod. A first spring is fixedly installed on the inner side of the fixing frame. A washer is fixedly installed at the end of the first spring away from the fixing frame. A positioning post is fixedly installed inside the washer. A placement hole is provided inside the second vertical column. A storage hole is provided inside the first vertical column. A splicing hole is provided inside the first vertical column. The positioning post is inserted into the splicing hole of the fitting first vertical column after disengaging from the placement hole, allowing the two devices to be spliced ​​together. Multiple devices form a whole, providing stronger protection during use.

[0007] Preferably, the positioning post is inserted into the splicing hole, the positioning post is inserted into the storage hole, and the positioning post is inserted into the placement hole to store the positioning post.

[0008] Preferably, the positioning post is slidably installed inside the rotating rod and the fixing frame, and the washer is in contact with the rotating rod, at which time the first spring is in its initial stretched state.

[0009] Preferably, the installation mechanism includes a plug cylinder, which is fixedly installed at the bottom of the first vertical column and at the bottom of the second vertical column. A turntable is rotatably installed inside the plug cylinder, and four movable columns are movably installed inside the turntable. A plug block is fixedly installed outside the movable columns. Four limiting grooves are provided inside the plug cylinder. A first rotating shaft is fixedly installed at the top of the turntable, and a first bevel gear is fixedly installed at the top of the first rotating shaft. A second rotating shaft is rotatably installed inside both the first and second vertical columns. A second bevel gear is fixedly installed at the end of the second rotating shaft near the first bevel gear. Two fixed columns are fixedly installed on the front of both the first and second vertical columns. A locking block is rotatably installed outside the fixed column. A second spring is provided between the two locking blocks, so that the two locking blocks are engaged with the outside of the second rotating shaft, preventing the second rotating shaft from rotating.

[0010] Preferably, the locking block is disposed outside the second rotating shaft, and the second bevel gear meshes with the first bevel gear, so that the first rotating shaft drives the turntable to rotate.

[0011] Preferably, the first rotating shaft is rotatably installed inside the insert, and the insert blocks are slidably installed inside the limiting groove. The four insert blocks protrude from the outside of the insert under the limiting action of the limiting groove and are inserted into the ground, so that the insert is in closer contact with the ground.

[0012] Compared with the prior art, this utility model provides a protective device for hydraulic construction, which has the following beneficial effects:

[0013] 1. This protective device for water conservancy construction, through the two locking blocks, no longer limits the second rotating shaft. Then, with the cooperation of the second rotating shaft, the second bevel gear, the first bevel gear, the turntable, the movable column and the limiting groove, it drives the four insert blocks to protrude from the outside of the insert cylinder and insert into the ground, so that the insert cylinder is in closer contact with the ground, thereby making the installation of the first vertical column and the second vertical column faster and more stable.

[0014] 2. Based on this, the present invention allows the telescopic fence to be folded or extended by sliding a slider inside the first and second vertical columns. When in use, the telescopic fence is extended to protect the construction site. When not in use, the positioning column is inserted into the storage hole of the first vertical column under the action of the first spring, so that the first and second vertical columns can store the telescopic fence after it is folded, thus saving storage space when not in use and making it easy to carry.

[0015] 3. Based on this, when the construction site is large and multiple devices are needed, the first vertical column of the next device is placed against the already installed second vertical column, and the positioning column is inserted into the splicing hole of the first vertical column after being removed from the placement hole. This allows the two devices to be spliced ​​together, and multiple devices can be combined into a whole, which provides stronger protection during use. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1:

[0026] Please see Figure 1-3 This utility model provides a technical solution: a protective device for water conservancy construction, including a first vertical column 1 and a second vertical column 2. Both the first vertical column 1 and the second vertical column 2 are provided with two extension mechanisms 3 inside, and both the first vertical column 1 and the second vertical column 2 are provided with an installation mechanism 4 at their bottom.

[0027] Furthermore, the extension mechanism 3 includes a slider 31, which is slidably installed inside the first vertical column 1. Two sliders 31 are slidably installed inside both the first vertical column 1 and the second vertical column 2. A telescopic fence 32 is provided between the two sets of sliders 31. A rotating column 33 is rotatably installed inside the second vertical column 2. A rotating rod 34 is fixedly installed on the front of the rotating column 33. A fixing frame 35 is fixedly installed on the front of the rotating rod 34. A first spring 36 is fixedly installed on the inner side of the fixing frame 35. A gasket 37 is fixedly installed at the end of the first spring 36 away from the fixing frame 35. A positioning post 38 is fixedly installed inside the gasket 37. A placement hole 39 is opened inside the second vertical column 2, and a storage hole 310 and a splicing hole 311 are opened inside the first vertical column 1. The positioning post 38 is disengaged from the placement hole 39 and inserted into the splicing hole 311 of the fitting first vertical column 1, allowing the two devices to be spliced ​​together. Multiple devices form a whole, providing stronger protection during use.

[0028] Furthermore, the positioning post 38 is inserted into the splicing hole 311, the storage hole 310, and the placement hole 39 to store the positioning post 38.

[0029] Furthermore, the positioning pin 38 is slidably installed inside the rotating rod 34 and the fixing frame 35, and the washer 37 is in contact with the rotating rod 34. At this time, the first spring 36 is in the initial stretched state.

[0030] Example 2:

[0031] Please see Figure 4-5 Furthermore, in conjunction with Embodiment 1, the installation mechanism 4 includes a plug cylinder 41, which is fixedly installed at the bottom of the first vertical column 1. A plug cylinder 41 is also fixedly installed at the bottom of the second vertical column 2. A turntable 42 is rotatably installed inside the plug cylinder 41. Four movable columns 43 are movably installed inside the turntable 42. A plug block 44 is fixedly installed on the outside of each movable column 43. Four limiting grooves 45 are provided inside the plug cylinder 41. A first rotating shaft 46 is fixedly installed on the top of the turntable 42, and a first conical shape is fixedly installed on the top of the first rotating shaft 46. Gear 47, a second shaft 48 is rotatably mounted inside the first vertical column 1 and the second vertical column 2. A second bevel gear 49 is fixedly mounted at one end of the second shaft 48 near the first bevel gear 47. Two fixing posts 410 are fixedly mounted on the front of the first vertical column 1 and the second vertical column 2. Locking blocks 411 are rotatably mounted on the outside of the fixing posts 410. A second spring 412 is provided between the two locking blocks 411, so that the two locking blocks 411 are engaged with the outside of the second shaft 48, so that the second shaft 48 cannot rotate.

[0032] Furthermore, the locking block 411 is located outside the second rotating shaft 48, and the second bevel gear 49 meshes with the first bevel gear 47, causing the first rotating shaft 46 to drive the turntable 42 to rotate.

[0033] Furthermore, the first rotating shaft 46 is rotatably installed inside the insert 41, and the insert block 44 is slidably installed inside the limiting groove 45. Under the limiting action of the limiting groove 45, the four insert blocks 44 protrude from the outside of the insert 41 and are inserted into the ground, making the insert 41 more closely connected to the ground.

[0034] In actual operation, when this device is used, the positioning post 38 is pulled out of the receiving hole 310 of the first vertical post 1. At this time, the pad 37 approaches the fixing frame 35, causing the first spring 36 to be compressed. The first spring 36 is initially in a stretched state. Then, the rotating rod 34 is rotated so that the positioning post 38 corresponds to the placement hole 39. Then, the positioning post 38 is released. At this time, the first spring 36 rebounds and drives the pad 37 to move, so that the positioning post 38 is inserted into the placement hole 39 of the second vertical post 2, thereby unlocking the first vertical post 1 and the second vertical post 2. Then, the first vertical post 1 and the second vertical post 2 are pulled to both sides until they reach a suitable position. After that, the first vertical post 1 and the second vertical post 2 are... The inserts 41 at the bottom of the vertical column 2 are all inserted into the ground. Squeezing the two locking blocks 411 inward compresses the second spring 412, which is initially in a stretched state. This causes the locking blocks 411 to rotate outside the fixed column 410, disengaging them from the second rotating shaft 48 and ceasing to limit its movement. The second rotating shaft 48 then rotates, driving the second bevel gear 49 to rotate. The first bevel gear 47 meshes with the second bevel gear 49, causing the first rotating shaft 46 to drive the turntable 42 to rotate. This causes the four movable columns 43 to move inside the turntable 42, causing the four inserts 44 to protrude under the limiting action of the limiting groove 45. The outside of the insert 41 is inserted into the ground, making the contact between the insert 41 and the ground closer. This allows for faster and more stable installation of the first vertical post 1 and the second vertical post 2, avoiding the problem that the first vertical post 1 and the second vertical post 2 are not easily tilted when subjected to external impacts due to insufficient stability caused by the insert 41 alone, thus failing to protect the construction site. When the distance between the first vertical post 1 and the second vertical post 2 changes, the slider 31 slides inside the first vertical post 1 and the second vertical post 2, causing the telescopic fence 32 to fold or extend. When in use, the telescopic fence 32 extends to intercept and protect the construction site. When not in use, the positioning post 38 is inserted into the storage hole 310 of the first vertical post 1 under the action of the first spring 36, so that after the telescopic fence 32 is folded, the first vertical post 1 and the second vertical post 2 store the telescopic fence 32, saving storage space when not in use and making it easy to carry. When the construction site is large and multiple devices need to be used, the first vertical post 1 of the next device is placed against the already installed second vertical post 2, and the positioning post 38 is removed from the placement hole 39 and inserted into the splicing hole 311 of the first vertical post 1, so that the two devices can be spliced ​​together and multiple devices can be combined into a whole, which has a stronger protective effect when in use.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
