Abstract
The utility model discloses an environment friendly sluice opening/closing machine resisting theft and dust. The machine is characterized in that a screw bolt is arranged in the shell of the machine, the lower part of a nut connected with the screw bolt is connected with a suspender, the suspender is connected with the sluice having a single-layer structure or the inner wall of the sluice having an internal cavity, and a sealing cover is arranged on the shell and provided with a lock. The utility model takes up a low spacious height, resists dust, theft and damage, effectively prevents its lubricant oil from flowing into water and causing pollution, and avoids the erosion by water to extend its service life.
Description
The utility model relates to a kind of hydraulic engineering gate control assembly, particularly a kind of antitheft, dustproof, environment-friendly type sluice headstock gear.
At present, the nut that uses on the sluice, screw rod Vertical Lift headstock gear, its structure is: nut is positioned on the headstock gear frame, and gate is connected with screw rod, and it is to drive the nut rotation by handwheel to make the upper and lower motion of screw rod, realizes opening and closing the purpose of gate.Because behind the gate opening, screw rod is stretched in outward on the headstock gear frame, when so the gate hoisting depth is excessive, the height that need box out or increase the headstock gear machine room at the top of headstock gear machine room can, and for the small-sized sluice of no headstock gear machine room, behind the gate opening, the screw rod plate that the water-robbery person very easily will be stretched in outward on the frame is curved, makes gate can't close stolen water out of control or turns headstock gear nut stolen water with wrench.Simultaneously, for the screw rod that exposes throughout the year, lubrication oil on it not only through wind, Exposure to Sunlight, drench with rain, natural environment influence such as sandstorm is easily aging, scleroma, hinder screw drive, and, the lubrication oil that flows in the water has also caused pollution, and that the bottom screw rod is often met torrent is wet, and corrosion and destruction all makes be affected the application life of headstock gear to a certain extent.
The purpose of this utility model is to provide a kind of antitheft, dustproof, environment-friendly type sluice headstock gear, its long service life, and it is highly low to take up space, and can effectively avoid stolen water out of control.
Its concrete solution is: screw rod is positioned in the casing, and is connected with a suspension rod on the nut that screw rod is connected, and suspension rod is connected with gate, and housing is provided with capping.
In addition then, what gate adopted is individual layer or the gate with inner chamber, and suspension rod is connected with the gate inwall with inner chamber.
Moreover capping is provided with tapered end, makes its capping need use the special opening tool chuck to open.
The utility model adopts full-closed structure; and by going up; the nut of following motion drives gate opening/closing by the suspension rod that is connected with the gate inner chamber; it is dustproof that it has not only been played; antitheft and vandal-proof protective effect; and; prevented that effectively the water that causes in the flow of lubricant entry on it from polluting; avoided the etch of water; improved application life greatly; simultaneously; also greatly reduce the spatial altitude that headstock gear occupies, and the capping that headstock gear adopts need can open with the special opening instrument has been played also antitheft; the anti-misoperation effect; particularly under the situation that water price improves at present, also supply water accurate safe guarantee is provided for the irrigated area.
In conjunction with the accompanying drawings the utility model is described in detail below by embodiment:
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is for opening the special opening tool construction schematic diagram of embodiment 1 capping.
Fig. 3 is the structural representation of embodiment 2.
Embodiment 1.
Among Fig. 1, screw rod 10 is provided with annular projection 5, and it is positioned in the hood 6 on casing top by two thrust bearings 4 and thrust ring 3, realizes screw rod 10 location, and the purpose of the nut 11 upper and lower motions that are connected with screw rod.Gate 14 is a double-decker, and suspension rod 13 upper ends are connected with nut 11, and the lower end is welded on the bottom of double-decker gate 14 cavitys, and screw rod 10 is provided with sheath 8.The screw top of hood 6 is connected with a capping 1, and the tapered end in the capping 1 is a First Five-Year Plan limit connected in star 16.The casing that is made of sheath 8 and hood 6 can be fixed on the keying frame 9 by bolt 7, and 14 at sheath 8 and gate are provided with sealing ring 12, and the bottom of gate 14 is connected with water seal 15.
When opening and closing gate, should at first use special opening tool chuck shown in Figure 2, the key end that will have the pentagon projection places in the groove 16 of capping 1 tapered end, opens capping 1, then be stuck in rotation on the pivot pin 2 of screw rod 10, drive screw rod 10 and open and close gates with another end of dop with notch.It is applicable to that the gate opening height uses when 1～2 times of depth of water.
Embodiment 2
Among Fig. 3, removing gate 17 is the single layer structure gate, and suspension rod 13 is connected with the top of gate, and the tapered end in the hood 6 top cappings is outside the triangle groove, and all the other structures are identical with embodiment 1.It is applicable to that the gate opening height uses during with headwater depth at 2 times.
Claims (3)
1, a kind of antitheft, dustproof, environment-friendly type sluice headstock gear, it is characterized in that screw rod (10) is positioned in the casing, be connected with a suspension rod (13) on the nut that is connected with screw rod (11), and suspension rod (13) is connected with gate, and housing is provided with capping (1).
2, a kind of antitheft, dustproof, environment-friendly type sluice headstock gear according to claim 1, it is characterized in that gate adopts for the gate of single layer structure (17) or have the gate (14) of inner chamber, and suspension rod is connected with the inwall of gate (14).
3, a kind of antitheft, dustproof, environment-friendly type sluice headstock gear according to claim 1 is characterized in that capping (1) is provided with tapered end.
