Description
Technical field
The utility model relates generally to water conservancy projects technical field, more particularly to a kind of water conservancy air regenerating device.
Background technology
It is both provided with to place the close of the water pumping mechanism for flood discharge on some water conservancy projects such as dykes and dams, anti-flood valve
Room due to closing on rivers and lakes, causes air in the secret room very moist, easily generates substantial amounts of mould, influence total
Firmness, it is backroom to some in addition, to be also easy to cause the internal temperature in hot weather excessively high for closed space completely
Circuit arrangement causes security risk.
The content of the invention
In view of the deficienciess of the prior art, the utility model is intended to provide and a kind of can guarantee secret room inner sealing
The water conservancy air regenerating device with external ventilation is realized simultaneously.
To achieve the above object, the utility model provides following technical solution：
A kind of water conservancy air regenerating device, includes pedestal, and pump cover is removably secured on the pedestal, in the pump cover
The fixed pump housing in top, the pump body is hollow to form installation cavity, and the installation cavity is sealed by the pump cover, in the peace
Pump shaft is provided in behaveing affectedly, motor is provided in the pedestal, described pump shaft one end is connected on the output shaft of the motor,
It is rotated by the Electric-motor driven pumps axis, the other end of the pump shaft extends in the top of the pump housing top surface, in the pump shaft
Turbine is socketed on the other end, the fixed turbine seat above the pump housing sets housing, the shell in the turbine seat upper cover
Body and the turbine seat form ventilation lumen, offer air outlet on the housing, be provided in the turbine seat bottom into
Tuyere.
As the preferred of the utility model, turbine coverplate is provided in the ventilation lumen, the turbine coverplate is located at
The top of the turbine.
As the improvement of the utility model, described be removably secured refers to that the pump cover is bolted on the bottom
On seat.
As further improvement of the utility model, through hole is opened up on the pump housing, the bolt is fed through described
The pump housing, pedestal and pump cover are fixed together by through hole, the bolt.
As the preferred of the utility model, fixed upper bearing (metal) and lower bearing on the inner wall of the installation cavity, it is described on
Bearing and lower bearing are set on the pump shaft.
As the further preferred of the utility model, oil inlet pipe is connected on the pump housing, external lubricating oil is by institute
Oil inlet pipe is stated to enter in installation cavity.
Compared with prior art, the utility model has the advantage of：Air-flow is formed by the high-speed rotation of turbine, so as to
Gas inside secret room is drawn to outside, while air pressure inside can be less than external pressure, and when turbine stops operating, inside
Under the influence of outer draught head, outer gas stream can pour in inside, and the overall process of a gas exchanges is completed with this.
Description of the drawings
Fig. 1 is the structure diagram of water conservancy air regenerating device in the utility model embodiment.
Specific embodiment
The embodiment of water conservancy air regenerating device in the utility model is described further referring to the drawings.
As shown in drawings, the present embodiment is a kind of water conservancy air regenerating device, includes pedestal 1, passes through bolt 13 on pedestal
Pump cover 15 is removably secured, the fixed pump housing 2 above pump cover, the pump body is hollow to form installation cavity, installation cavity
It is sealed by pump cover, pump shaft 11 is provided in installation cavity, motor is provided in the pedestal, pump shaft one end is connected to motor
On output shaft 3, when the motor is energized, output shaft quick rotation, and then pump shaft is driven to rotate,
Fixed upper bearing (metal) 6 and lower bearing 5, upper bearing (metal) and lower bearing are set on pump shaft on the inner wall of installation cavity,
In addition, in order to reduce the degree of wear of the pump shaft in high-speed rotation, outside framework oil seal 4 is also arranged on pump shaft, in the side of the pump housing
Portion is connected to oil inlet pipe 14, and external lubricating oil is entered by oil inlet pipe 14 in installation cavity, and is sprayed on outside framework oil seal 4.
The other end of pump shaft extends in the top of pump housing top surface through housing, and turbine 8 is socketed on the other end of pump shaft,
The also fixed turbine seat 7 above the pump housing sets housing 16 in turbine seat upper cover, and housing forms closed ventilation with turbine seat
Chamber offers air outlet 10 on housing, is provided in turbine seat bottom into tuyere 12.When turbine quick rotation, can be formed
Thrust so that gas is discharged towards 10 position of air outlet, so that forming negative pressure, ventilation lumen and enclosed interior inside ventilation lumen
Draught head the air inside secret room can be caused by being entered into tuyere in ventilation lumen, then to be discharged again by air outlet.And
The rotation of turbine is intermittent, and when turbine stops operating, under the influence of internal and external pressure difference, outer gas stream can pour in secret room
Inside completes the overall process of a gas exchanges with this.
In order to turbine will be protected, prevent the impulse turbine when extraneous air flows back, turbine coverplate is provided in ventilation lumen
9, turbine coverplate is located at the top of the turbine.
The above makes the preferred embodiment of the utility model, does not depart from for those of ordinary skill in the art
On the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model
Scope.
