Abstract
The invention provides a hydraulic and manual pollution discharge device for an airplane water wagon. The hydraulic and manual pollution discharge device is characterized by comprising a worm, a ball valve, a sector gear, a worm handle, a worm handle base, a spherical end, a handle guide groove, a limiting base, a handle limiting dowel, a spring, a hydraulic oil cylinder, a liquid drainage pipeline and a hydraulic oil cylinder installation base. According to an existing pollution discharge device, a valve is mistakenly opened easily when errors are caused by the utilization of a hydraulic device, and then sewage flows everywhere due to the fact that the valve is opened. According to the hydraulic and manual pollution discharge device, the phenomenon that the valve is mistakenly opened easily when the errors are caused by the hydraulic device is avoided, the phenomena that the hydraulic device causes the errors easily and then the sewage in a box flows everywhere due to the fact that the valve is opened are avoided, the emergency operation function is achieved, and the reliability, simplicity and convenience of work are improved.
Description
Technical field
The present invention relates to a kind of drainage device, particularly relate to aircraft waterwheel drainage device.
Background technique
At present, the whole world existing aircraft waterwheel drainage device is hydraulic pressure installation, because hydraulic pressure installation work has no idea to reach perfect, easily cause error, during error, cause valve mistake to open, when filling sewage and transport, the sewage in case can, because of the trickling everywhere of opening of valve, cause traffic congestion and befouling environment in serious airdrome.Therefore, processing need to spend a large amount of manpower physical resources and clears up.
Summary of the invention
A kind of aircraft waterwheel hydraulic pressure and manual blowdown device have been the object of this invention is to provide, from following principle, solve this defect: can meet can be when hydraulic pressure installation be made a fault at hydraulic pressure and manual blowdown device, can mistake not open valve, now recycle the opening and closing that manual operating device is realized valve.
In order to achieve the above object, the invention provides following technological scheme:
Aircraft waterwheel hydraulic pressure and a manual blowdown device, is characterized in that it comprises: worm screw, ball valve, tooth sector, worm screw handle, worm screw handle set, spherical termination, handle guide groove and position limit socket, handle position-limitting pin and spring, hydraulic jack, fluid discharge pipeline, hydraulic jack mounting base.In invention, owing to utilizing hydraulic pressure installation easily to cause when error valve mistake to open, sewage can be because of the trickling everywhere of opening of valve; Therefore, while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, and avoids hydraulic pressure installation easily to cause error, and the sewage in case can be realized emergency operation function because of the trickling everywhere of opening of valve, improves the reliability simplicity of work.
The invention has the beneficial effects as follows: while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, and avoids hydraulic pressure installation easily to cause error, the sewage in case can be realized emergency operation function because of the trickling everywhere of opening of valve, improves the reliability simplicity of work.Can bring good economic benefit, cost-saving, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the structural representation of aircraft waterwheel hydraulic pressure and manual blowdown device.
Fig. 2 is handle position-limitting pin under worm screw lock state of the present invention and the structural representation of spring.
Fig. 3 is the structural representation of handle set of the present invention.
Fig. 4 is the linkage structure schematic diagram of hydraulic jack mounting base of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As Fig. 1 and as shown in, aircraft waterwheel hydraulic pressure and a manual blowdown device, is characterized in that it comprises: worm screw 1, ball valve 2, tooth sector 3, worm screw handle 4, worm screw handle set 5, spherical termination 6, handle guide groove and position limit socket 7, handle position-limitting pin and spring 8, hydraulic jack 9, fluid discharge pipeline 10, hydraulic jack mounting base 11.In invention, owing to utilizing spring and the position-limitting pin of handle position-limitting pin and spring 8, can control to the characteristic of handle release and locking, in conjunction with 6 designs of spherical termination; Therefore, while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, and avoids hydraulic pressure installation easily to cause error, and sewage can be realized emergency operation function because of the trickling everywhere of opening of valve, improves the reliability simplicity of work.
As shown in Figure 1 and Figure 2, when aircraft waterwheel transports the Water Tank of filling sewage, now worm screw handle 4, in the bottom of handle position-limitting pin and spring 8, is fixed with position-limitting pin and spring, because worm screw 1 can be realized the function with the large-scale ball valve 2 of manual operation with the drive mechanism of tooth sector 3.
As shown in Figure 3, spherical termination 6 is used in worm screw handle 4 one end, realize to rotate and on lift worm screw handle 4 and carry out release.
As shown in Figure 4, hydraulic jack 9 is used hydraulic jack mounting base 11 to be directly installed on ball valve 2, can save materials and installing space.
The working principle of above-mentioned aircraft waterwheel hydraulic pressure and manual blowdown device is: when aircraft waterwheel transports the Water Tank of filling sewage, now worm screw handle 4 is on the top of handle position-limitting pin and spring 8, with position-limitting pin and spring, fix, after pressing down worm screw handle 4 and putting in place, worm screw 1 is realized engagement with tooth sector 3, can be by hydraulic jack 9 positive locks, because worm screw 1 can be realized the function with the large-scale ball valve 2 of manual operation with the drive mechanism of tooth sector 3.Normal manually-operable, turn worm screw handle 4 can be closed ball valve 2 counterclockwise, and turn worm screw handle 4 can be opened ball valve 2 clockwise, and worm screw 1 can be realized the function with the large-scale ball valve 2 of manual operation with the drive mechanism of tooth sector 3.As shown in Figure 3, spherical termination 6 is used in worm screw handle 4 one end, realize to rotate and on lift worm screw handle 4 and carry out release.When can prevent that hydraulic system is malfunctioning thus, sewage can, because of the opening of ball valve 2 mistakes, flow out from fluid discharge pipeline 10.When can prevent that hydraulic system is malfunctioning thus, sewage can, because of the opening of ball valve 2 mistakes, flow out from fluid discharge pipeline 10.If lift to behind position from worm screw handle 4, worm screw handle 4 is on the top of handle position-limitting pin and spring 8, and worm screw 1 is removed engagement with tooth sector 3, and now hydraulic jack 9 can move, and realizes electricity consumption console keyboard and opens and throttle down.
According to above-mentioned working principle: owing to utilizing spring and the position-limitting pin of handle position-limitting pin and spring, can control to the characteristic of handle release and locking, in conjunction with the design of spherical termination; Therefore, while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, avoid hydraulic pressure installation easily to cause error, sewage can be because of the trickling everywhere of opening of valve, realize the function of locking oil hydraulic cylinder and light manually-operable valve, emergency operation function, makes simply, improves the reliability simplicity of work.
