Device is separately provided, and is linked by way of signal transmission, this just need to establish therebetween conducting wire,
The electrical connections such as signal wire, and environment is more moist in water conservancy projects, just the leakproofness to conducting wire etc., corrosion resistance etc. carry for this
Higher requirement is gone out.
The content of the invention
In view of the deficienciess of the prior art, the utility model is intended to provide one kind based on mechanical water level detecting to carry out certainly
The pump housing of speed governing.
To achieve the above object, the utility model provides following technical solution：
It is a kind of based on water level detecting from the speed governing pump housing, include water-level detecting device, the water-level detecting device includes
Pedestal is provided with positioning anchor in the base bottom, and the positioning anchor can be plugged in soil to fix the pedestal,
The fixed housing above the pedestal is formed with closed installation cavity the enclosure interior is hollow, in the installation cavity
Closed container is provided with, in the fixed clump weight in closed container bottom, the fixed connecting rod above the closed container,
Mechanical linkage switch valve is additionally provided in the installation cavity, described connecting rod one end is fixed on the closed container, and the other end connects
Then the mechanical linkage switch valve offers permeable mesh in the housing bottom, and external water can pass through the permeable net
Hole is entered in the installation cavity.
As the improvement of the utility model, sealing plate is provided in the installation cavity, the sealing plate is by the installation
Chamber is separated into epicoele and cavity of resorption, and the mechanical linkage switch valve is located in epicoele, and the closed container is located in the cavity of resorption.
As further improvement of the utility model, through hole is offered on the sealing plate, the connecting rod is threaded through institute
It states in through hole, the fixed sealing ring on the inner wall of the through hole, the sealing ring has elasticity, and the sealing ring is clamped in
Between the through-hole wall and the connecting rod.
As the preferred of the utility model, the positioning anchor is pointed anchor.
Compared with prior art, the utility model has the advantage of：The water-level detecting device passes through mechanical linkage switch valve
It solves the problems, such as to need manual switch, can really realize unmanned control, automatic speed regulation is carried out to the pump housing.
Description of the drawings
Fig. 1 is from the structure diagram of the speed governing pump housing in the utility model embodiment.
Specific embodiment
Referring to the drawings to being described further in the utility model from the embodiment of the speed governing pump housing.
As shown in drawings, the present embodiment for it is a kind of based on water level detecting from the speed governing pump housing, include water-level detecting device,
The water-level detecting device includes pedestal 1, and base bottom is provided with positioning anchor 2, the positioning anchor be pointed anchor, bottom grafting
In ground or soil so that the bottom surface of pedestal is concordant with ground, and pedestal is fixed on the ground.It is fixed in the top of pedestal
Housing 3, housing is preferably transparent tempered glass housing, and the water level of enclosure interior is estimated convenient for staff, is made
It obtains when aftermentioned mechanical linkage switch valve is due to malfunction and failure, can also be estimated water level by staff and be taken corresponding
Measure.
Enclosure interior is hollow to be formed with closed installation cavity, and closed container 4 is provided in installation cavity, is opened in housing bottom
Equipped with permeable mesh 5, external water can enter the inside of installation cavity by the permeable mesh, and subsequent external water constantly gushes
Enter, the water level in installation cavity is caused to be gradually increasing, in the fixed clump weight 6 in closed container bottom, clump weight is made of wooden unit,
Its weight is pre-set, and can be replaced by staff, when water level rises to clump weight position, counterweight
Block can be swum on the water surface, continue to rise with water level, and clump weight also rises therewith in the height of installation cavity, so as to drive
The height of closed container rises, and in the fixed connecting rod 7 in the top of closed container, mechanical linkage switch is additionally provided in installation cavity
Valve 8, connecting rod one end are fixed on the closed container, and the other end is connected to mechanical linkage switch valve, when closed container rises,
Connecting rod can be driven to rise, so as to jack up mechanical linkage switch valve, the control switch of mechanical linkage switch valve, that is, water pump, when its quilt
During jack-up, starting mode of pump carries out draining, conversely, when a period of time draining is carried out after, during water surface decline, the height of connecting rod is also therewith
It is gradually reduced, until mechanical linkage switch valve resets, at this point, water pump is stopped.
It since mechanical linkage switch valve is precise part purchased in market, therefore needs to do water-proofing treatment to it, specifically, described
Sealing plate 9 is provided in installation cavity, installation cavity is separated into epicoele and cavity of resorption by sealing plate, and mechanical linkage switch valve is located at epicoele
In, closed container is located in cavity of resorption.Through hole is offered on sealing plate, connecting rod wears in through-holes and can be risen compared with through hole
Drop movement, fixed sealing ring 91, sealing ring are clamped in the through-hole wall with elasticity, sealing ring on the inner walls of the via
Between the connecting rod, since it has elasticity, therefore during connecting rod lifting, excessive frictional force will not be caused.
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.
