Description

Automatic water replenishing device

Technical Field

The utility model relates to a cooling tower field, concretely relates to automatic water supply device is applied to equipment such as cooling tower water tank, basin.

Background

The automatic water supply of water tank is usually realized through the ball-cock assembly, but cooling tower water tank is capacious, highly high, and the ball-cock assembly will set up in the upper portion of water tank, and the quick-wear part like the change of piston in the ball-cock assembly then needs the people to climb to the water tank top and accomplishes, to this kind of easy wearing and tearing spare of piston, because maintenance, change comparatively frequently, so traditional this kind of design, very inconvenient, and climb to the top and accomplish this kind of operation and also have certain danger.

SUMMERY OF THE UTILITY MODEL

In view of the not enough of background art, the utility model provides an automatic water supply device, the problem of solution is among the prior art, and the automatic water supply device maintenance of cooling tower water tank needs the operation of ascending a height, and it is inconvenient to maintain, and has certain danger.

For solving the technical problem, the utility model provides a following technical scheme:

automatic water supplementing device, including setting up the floater in the water tank, the one end of floater one end fixed connection stay cord, the water tank lower part outside is equipped with the inlet tube, inlet tube intercommunication connecting pipe, connecting pipe one end stretches into inside the water tank and seals the port through the shrouding, set up first through-hole on the shrouding, the fixed pulley that sets up in water tank top, the stay cord other end passes first through-hole fixed connection piston after walking around the fixed pulley, piston and sliding connection in the connecting pipe, coil spring's one end is fixed to the opposite side of piston, coil spring's other end fixed connection fixed plate, the fixed plate is fixed in the connecting pipe, be equipped with a plurality of second through-holes on the fixed plate, the part periphery that the connecting pipe is located the water tank is equipped.

When the spiral spring is selected and the floating ball is designed, relevant factors are considered, and corresponding conditions are met. When the spiral spring is in a natural state, the piston is positioned at one side of the third through hole close to the fixed plate, the distance between the piston and the sealing plate is set as D, the force F1 which is required when the spiral spring is pulled to the sealing plate is equal to kD, k is the stiffness coefficient of the spiral spring, and the gravity G of the floating ball is set to be greater than G1, so that when the water level is reduced, the floating ball also descends to drive the piston to move towards the sealing plate, water can enter the water tank through the second through hole on the fixed plate and the third through hole on the connecting pipe, meanwhile, the floating ball floats on the water surface and can ascend along with the ascending of the water surface, therefore, the buoyancy of the floating ball is set as F2, F2 is equal to Vg, and V is the displacement of the floating ball, therefore, when the floating ball is designed, the floating ball is designed to be hollow, and the condition that V meets the condition that F2 is equal to G > Vg, namely, the rho > k, the displacement of the floating ball and the stiffness coefficient of the spiral spring meet the requirements. The floater can be along with the ascending decline of the surface of water and the decline of rising simultaneously, and the water level descends, and the floater descends, and the piston is being drawn and is moving to shrouding department, and water gets into the water tank from the third through-hole on the connecting pipe, realizes the moisturizing, and the water level rises, and the floater rises, and coil spring shrink, and the piston moves to the fixed plate side, and the third through-hole is kept apart by the piston, stops the moisturizing.

Preferably, the plurality of second through holes are uniformly distributed on the fixing plate in the circumferential direction.

Preferably, the third through holes are uniformly distributed along the periphery of the connecting pipe.

Preferably, set up the stop valve on the inlet tube, be convenient for to break off water, overhaul the change to spare part after emptying water tank water-logging.

The utility model has the advantages of compared with the prior art: structural design is reasonable, can automatic water supply, simultaneously, with most part design in the bottom of water tank, the maintenance needn't climb to the water tank top, avoids ascending a height the operation, and convenient operation has reduced danger, and the practicality is strong.

Drawings

The utility model discloses there is following figure:

FIG. 1 is a schematic view of the present invention;

FIG. 2 is an enlarged view of A in FIG. 1;

fig. 3 is a schematic view of the fixing plate of the present invention.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1-3, the automatic water replenishing device includes a floating ball 2 disposed in a water tank 1, one end of the floating ball 2 is fixedly connected to one end of a pull rope 3, a water inlet pipe 4 is disposed on the outer side of the lower portion of the water tank 1, the water inlet pipe 4 is communicated with a connecting pipe 5, one end of the connecting pipe 5 extends into the water tank 1 and seals a port through a sealing plate 6, a first through hole 7 is disposed on the sealing plate 6, a fixed pulley 8 is fixedly disposed on the top of the water tank 1, the other end of the pull rope 3 bypasses the fixed pulley 8 and then passes through the first through hole 7 to be fixedly connected with a piston 9, the piston 9 is disposed in the connecting pipe 5 and slidably connected with the connecting pipe 5, one end of a coil spring 10 is fixed to the other side of the piston 9, the other end of the coil spring 10 is fixedly connected, the connecting pipe 5 is provided with a plurality of third through holes 13 at the periphery of the part located in the water tank 1.

When the spiral spring 10 is selected and the floating ball 2 is designed, relevant factors are considered, and corresponding conditions are met. The working principle is that the floating ball 2 can rise and fall simultaneously along with the rise and fall of the water surface, the water level falls, the floating ball 2 falls, the piston 9 is pulled to move towards the sealing plate 6, water enters the water tank 1 through the second through hole 12 in the fixing plate 11 and the third through hole 13 in the connecting pipe 5, water replenishing is achieved, the water level rises, the floating ball 2 rises, the spiral spring 10 contracts, the piston 9 moves towards the fixing plate 11 side, and the third through hole 13 is isolated by the piston 9 to stop water replenishing.

In addition, a plurality of the second through holes 12 are uniformly distributed on the fixing plate 11 in the circumferential direction.

In addition, the third through holes 13 are uniformly distributed along the periphery of the connecting pipe 5.

In addition, set up stop valve 14 on the inlet tube 4, be convenient for to the water cut off, overhaul the change to spare part after emptying water tank 1 internal water.
