Description

Technical Field

[0001] The utility model belongs to the field of water conservancy and hydropower slope construction protection equipment, and specifically relates to a slope construction protection device for water conservancy and hydropower projects. Background Technique

[0002] Slope construction in water conservancy and hydropower projects refers to a series of works for excavating or strengthening the surface slopes in water conservancy projects such as reservoirs, dams, diversion channels, etc., and hydropower station construction. Its main purpose is to ensure the stability and safety of the project structure, prevent geological disasters such as landslides and collapses. In the slope construction of water conservancy and hydropower projects, protective nets are needed to ensure construction safety, prevent falling rocks and sundries during construction, so as to ensure the safety of construction workers;

[0003] According to the Chinese patent application number: 202322116432.6, a slope construction protection device for water conservancy and hydropower projects is disclosed, which includes a storage box. A storage cavity is opened inside the storage box. A storage shaft is rotatably connected inside the storage cavity. A protective net is wound around the circumferential side of the storage shaft. An opening groove is opened on the side wall of the storage box. The opening groove communicates with the storage cavity. The size of the opening groove is smaller than that of the storage cavity. A rotating shaft is fixedly connected to the top of the storage shaft. The rotating shaft penetrates through the top of the storage box; by using the protective net, it effectively prevents sundries, stones, etc. on the slope from sliding or rolling down, reducing the risk of injury to construction workers and equipment. Moreover, the protective net is made of flexible materials, which is lighter, more flexible, and more convenient to carry, install and operate than rigid protective plates. Its flexible characteristics enable it to adapt to various complex terrains and construction environments. Compared with rigid protective plates, when encountering impacts, they may generate greater force rebounds, increasing the risk of injury to construction workers and equipment;

A protection net 2 is wound around the surface of the winding roller 104. One end of the protection net 2 is fixedly connected to the winding roller 104, and the other end of the protection net 2 is fixedly connected to the support plate 102. A driving assembly 3 is installed inside the installation box 103. The driving assembly 3 is used to drive the winding roller 104 to rotate. A limiting assembly 4 is arranged on the surface of the driving assembly 3. The limiting assembly 4 is used to limit the driving assembly 3. The driving assembly 3 includes a driven gear 301, a driving gear 302, a transmission rod 303, a handle 304, a first connecting rod 305, and a second connecting rod 307. One end of the transmission rod 303 is fixedly connected to the driven gear 301, and the other end of the transmission rod 303 penetrates into the inner cavity of the storage box 101 and is fixedly connected to the winding roller 104. The driving gear 302 meshes with the driven gear 301. The limiting assembly 4 includes a ratchet 401, a pawl 402, a tension spring 403, a limiting rod 404, and a pull rod 405.

Both ends of the second connecting rod 307 are fixedly connected to the ratchet 401 and the driven gear 301 respectively.

[0025] As Figures 1-4 shown, the storage box 101 and the support plate 102 can provide support for the protection net 2, enabling the protection net 2 to resist falling rocks or falling objects. The protection net 2 can be made of low-carbon steel wire, having a certain strength and toughness, so as to be able to resist the impact force of falling rocks. The storage box 101 can also provide a storage space for the protection net 2. The handle 304 drives the driving gear 302 to rotate through the first connecting rod 305. When the driving gear 302 rotates, it drives the driven gear 301 to rotate. When the driven gear 301 rotates, it drives the winding roller 104 to rotate through the transmission rod 303, thereby being able to wind up the protection net 2. The cooperation of the ratchet 401, the pawl 402, and the tension spring 403 can limit the driven gear 301, thereby being able to limit the winding roller 104 and prevent the winding roller 104 from rotating back under the action of a reverse force after being wound up.

[0026] Embodiment 2

[0027] Referring to Figure 1 、 2 and 4, this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0031] As Figure 1 、 2 As shown in FIGS. and 4, when the pull rod 405 is pulled, one end of the pull rod 405 drives the pawl 402 to move, so that the pawl 402 is separated from the ratchet wheel 401, thereby being able to release the limit on the ratchet wheel 401. The reset elastic force of the tension spring 403 can drive the pawl 402 to reset, so that the pawl 402 limits the ratchet wheel 401, and the limiting rod 404 can provide support for the pawl 402.

[0032] Embodiment 3

[0033] Referring to Figures 1-3 , this is the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.

[0037] As Figures 1-3 As shown in FIG., when the pull rod 405 is pulled, the pull rod 405 drives the pawl 402 to release the limit on the ratchet wheel 401. When the handle 304 is rotated counterclockwise, the handle 304 drives the driving gear 302 to rotate through the first connecting rod 305. When the driving gear 302 rotates, it drives the driven gear 301 to rotate. When the driven gear 301 rotates, it drives the winding roller 104 to wind up the protective net 2 through the transmission rod 303, so as to facilitate the storage and handling of the protective net 2.

[0038] In use, first pull the pull rod 405.
