Abstract
The utility model provides a water-stopping device of a wall-penetrating shaft sleeve of a bottom cross shaft driving flip plate gate and relates to a gate structure applied to water conservancy and hydropower. The water-stopping device comprises the wall-penetrating shaft sleeve, wherein a first retainer ring, a first copper bush, a second retainer ring and a second copper bush are arranged between a bottom cross shaft and the wall-penetrating shaft sleeve, the first retainer ring and the first copper bush are arranged at one end of the wall-penetrating shaft sleeve, a first rubber sealing ring is arranged between the wall-penetrating shaft sleeve and the first retainer ring, the outer side of the first rubber sealing ring is provided with a gland, and the gland is connected with the wall-penetrating shaft sleeve. The second retainer ring and the second copper bush are arranged at the other end of the wall-penetrating shaft sleeve, at least one second rubber sealing ring is arranged between the wall-penetrating shaft sleeve and the second retainer ring, a Haver pressing sleeve is arranged on the outer side of the second rubber sealing ring and connected with the wall-penetrating shaft sleeve, and one end of the wall-penetrating shaft sleeve facing a starting-shutdown machine. The water-stopping device of the wall-penetrating shaft sleeve of the bottom cross shaft driving flip plate gate adopts the rubber sealing rings, is good in elasticity, easy to compress, not prone to ageing and simple and convenient to install, is not influenced by a bottom shaft structure and does not cause water leakage.
Description
Technical field
The utility model relates to the gate structure that is applied to water conservancy and hydropower.
Background technology
In the fields such as China's urban water conservancy project, building of irrigation works and environmental renovation, irrigation, flood control, gate is just used widely.
Existing gate, its structure comprises gate flap, is fixed on end transverse axis, the drive unit of gate flap bottom, the two ends of end transverse axis are protruding through lock wall respectively, several free bearings are installed on end transverse axis, and on end transverse axis, antipriming are installed, antipriming adopts asbestos packing to carry out sealing, machining accuracy and quality of fit to end transverse axis are had relatively high expectations, and after long-time water-bed operation, generation is loosening aging, affects stagnant water effect, brings loss.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and the antipriming of the end transverse axis driving flap gate axle sleeve through walls that a kind of stagnant water effect is good is provided.
The purpose of this utility model is achieved in that end transverse axis drives the antipriming of flap gate axle sleeve through walls, comprise the axle sleeve through walls being nested with on end transverse axis, the first back-up ring, the first copper sheathing, the second back-up ring and the second copper sheathing are set between end transverse axis and axle sleeve through walls, the first back-up ring and the first copper sheathing are arranged on axle sleeve through walls one end towards river course, the first copper sheathing is arranged on the inner side of the first back-up ring, between axle sleeve through walls and the first back-up ring, the first rubber seal is set, at the arranged outside gland of the first rubber seal, gland is connected with axle sleeve through walls by bolt; Described the second back-up ring and the second copper sheathing are arranged on axle sleeve through walls one end towards headstock gear, the second copper sheathing is arranged on the inner side of the second back-up ring, the second rubber seal together with arranging at least between axle sleeve through walls and the second back-up ring, breathe out not clamping sleeve in the arranged outside of the second rubber seal, breathe out not clamping sleeve and be connected with axle sleeve through walls by bolt, connect side stand at axle sleeve through walls towards one end of headstock gear.
The utility model is by above design, change water-stopping structure into two sealing, adopt advanced composite material (ACM) 110 thiazolinyl silicon rubber, river course side adopts 1 road rubber seal, open and close pusher side and adopt 2 road rubber seal rings for seals (can according to actual conditions adjustment), rubber seal is bundled into certain size and as required with supporting glue special stickup.Rubber adopts hardness within the scope of 55 °, at gland and breathe out under the effect of friction top not, rubber ring is pressed into and compacting, because of rubber ring good springiness, therefore the machining accuracy to lower shaft and assembly precision require to reduce, can be not aging after long water-bed operation, therefore do not bring stagnant water effect disappearance and the loss that brings.
The utility model adopts rubber seal, its good springiness, and easily compression, is difficult for agingly, and is not subject to the structure influence of lower shaft, to installing simple and convenient and can not bringing the phenomenon of leaking.Fundamentally solved asbestos packing and easily produced and become flexible, poor flexibility, is difficult for compression, easily aging feature.On original wall-punching axis nested structure, improve, it is more reasonable to use simultaneously.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, for the antipriming of end transverse axis driving flap gate axle sleeve through walls, comprise the axle sleeve through walls 2 being nested with on end transverse axis 1, the first back-up ring 3, the first copper sheathing 4, the second back-up ring 7 and the second copper sheathing 8 are set between end transverse axis 1 and axle sleeve through walls 2, the first back-up ring 3 and the first copper sheathing 4 are arranged on axle sleeve 2 through walls one end towards river course, the first copper sheathing 4 is arranged on the inner side of the first back-up ring 3, between axle sleeve 2 through walls and the first back-up ring 3, the first rubber seal 5 is set, at the arranged outside gland 6 of the first rubber seal 5, gland 6 is connected with axle sleeve 2 through walls by bolt.The second back-up ring 7 and the second copper sheathing 8 are arranged on axle sleeve 2 through walls one end towards headstock gear, the second copper sheathing 8 is arranged on the inner side of the second back-up ring 7, twice the second rubber seal 9 is set between axle sleeve 2 through walls and the second back-up ring 7, breathe out not clamping sleeve 10 in the arranged outside of the second rubber seal 9, breathe out not clamping sleeve 10 and be connected with axle sleeve 2 through walls by bolt, connect side stand 11 at axle sleeve 2 through walls towards one end of headstock gear.
