Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a rain insensitive device for arrester, including arrester body 1, 1 fixed mounting of arrester body is on base 2, the outside of arrester body 1 is equipped with rain insensitive device, rain insensitive device is including installation section of thick bamboo 3 and first sunshade 8, 3 covers of installation section of thick bamboo are established in the outside of arrester body 1 and are fixed on base 2, first sunshade 8 is umbelliform structure and passes through the upper end of stand 9 fixed mounting at installation section of thick bamboo 3, utilize first sunshade 8, can tentatively discharge the rainwater side direction, avoid the rainwater direct and the 3 contacts of installation section of thick bamboo. Through setting up installation section of thick bamboo 3, can keep apart arrester body 1 and outside air, greatly stop the rainwater to the washing away of arrester body 1 and solarization of sunlight. The lateral wall of the installation cylinder 3 is provided with a plurality of groups of ring grooves which are linearly distributed, each ring groove is internally provided with a group of drainage mechanisms, the lateral wall of the installation cylinder 3 is provided with a plurality of groups of air holes 301, and the air holes 301 and the ring grooves are arranged at intervals. Through setting up drainage mechanism, can guide the rainwater that first sunshade 8 left as early as possible and discharge, avoid the rainwater to stop on the lateral wall of an installation section of thick bamboo 3, cause phenomenons such as corruption.
As shown in fig. 1 and 2, the drainage mechanism includes go-between 4, bracing piece 5 and reset spring 7, fixed mounting has the articulated seat 10 that the multiunit is the annular array and distributes on the go-between 4, bracing piece 5 is provided with a plurality of groups, every group bracing piece 5 all rotates with go-between 4 through articulated seat 10 and is connected, reset spring 7's one end and go-between 4 fixed connection, reset spring 7's the other end and bracing piece 5 fixed connection, utilize reset spring 7 both can play the effect that the side direction supported to bracing piece 5, can also produce the effect of downward deformation to bracing piece 5, thereby accelerate the discharge rate of rainwater. The upper surfaces of the supporting rods 5 in the same group of drainage mechanisms are adhered with annular rain-proof cloth 6, the annular rain-proof cloth 6 is made of PVC plastic-coated tarpaulin, and the PVC plastic-coated tarpaulin has the performances of water resistance, mildew resistance, cold resistance, aging resistance, static electricity resistance and the like; the breaking strength, the tearing elongation and the tearing strength of the PVC plastic-coated tarpaulin are greatly superior to those of the traditional tarpaulin; can be spliced by heat sealing, thereby avoiding the trouble of water leakage caused by sewing pinholes.
As shown in fig. 3, the connection ring 4 is formed by splicing two groups of shells having a C-shaped structure, a U-shaped insertion block 11 is fixedly mounted at the end portion of the left shell, and a positioning groove 12 matched with the U-shaped insertion block 11 is arranged at the end portion of the right shell.
