Abstract
The utility model discloses a protecting device for preventing dry burning, which is composed of a cover body, an installing nut and a float capable of freely swinging. The utility model is characterized in that the float with a magnet at the bottom is arranged at the outer end of the installing nut by a bracket and a pin shaft, a magnetic controller which is composed of a magnet, a push rod, a compression spring and a positioning bolt is arranged on the inner side of the installing nut. A micro-switch is arranged in the inner cavity of the cover body, and the push rod is aligned to a reed. The utility model has the advantages of reasonable design, simple structure and reliable work performance. An electric heater can be effectively and directly controlled to work by the elevation of water level. The protecting device is directly arranged at the bottom of a water tank, and installation and maintenance are convenient.
Description
The utility model relates to the heater technical field of water, specifically a kind ofly is used for solar energy and hydrophone auxiliary electrical heating water tank prevents the control protective device of dry combustion method.
The existing solar water heater that uses, major part all is equipped with auxiliary electric heater unit, so that most of the time can both provide hot water by solar water heater throughout the year.Because general solar water heater all is installed in the floor top, overhauls, checks very inconvenient.When the level sensor of water tank breaks down, be easy to occur the situation of electric heater dry combustion method, the lighter burns water tank, weight person even can cause the generation of fire.And the solar water heater auxiliary electric heater unit that uses at present; what its anti-dry burning device often adopted is to be provided with sheet metal between electrothermal tube and the insertion inside pipe wall near temperature controller; in case the dry combustion method phenomenon occurs, heat is passed to temperature controller by sheet metal, cutting off the electricity supply is protected.But this anti-dry burning device finally is to rely on temperature controller to cut off the electricity supply, in case the performance of temperature controller is stable inadequately, the anti-dry protective device of installation does not have due effect probably.
The purpose of this utility model just provides a kind of anti-dry protective device of in the water tank, directly controlling the work of solar water heater electrical heating elements that is installed in.
The purpose of this utility model is achieved in that this anti-dry protective device, is made up of lid, installation nut and floating drum, constitutes one by thread connection between lid and the installation nut.Mainly be by support, bearing pin a bottom to be set in the outer end that nut is installed to have floating drum magnet, that can freely swing, the inboard magnetic controller of being made up of magnet, push rod, stage clip and bolt that is provided with of nut is being installed, is being made between the magnet of the magnet of floating drum and magnetic controller corresponding; Inner chamber at lid is provided with microswitch, adopts tapping screw that microswitch directly is fixed on outer covering, and makes the push rod of magnetic controller aim at reed, and its lower end is provided with and draws lead.
Advantage of the present utility model: the one, reasonable in design, simple in structure, reliable working performance.Particularly by the attaching nut with the structure that liquid level floating drum and microswitch organically are combined into one, dwindled volume, be convenient to be directly installed on the auxiliary electrically heated water tank.The 2nd, according to the water tank characteristics, adopt spar structures, can directly control electric heater work by the lifting of following the tracks of water level.The 3rd, protective device is directly installed on water tank bottom, installation and maintenance are convenient.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
As shown in drawings, this anti-dry protective device is made up of lid 9, installation nut 4 and floating drum 1, adopts thread connection to constitute one between lid 9 and the installation nut 4.By support 3, bearing pin 2 bottom is set in the outer end that nut 4 is installed and has floating drum 1 magnet 15, that can freely swing, in the inboard that nut 4 is installed the magnetic controller of being made up of magnet 14, push rod 6, stage clip 12 and bolt 5 13 is set, makes between the magnet 15 of the magnet 14 of floating drum 1 and magnetic controller 13 corresponding.Adopt tapping screw directly microswitch 7 to be installed on the internal chamber wall of lid 9 simultaneously, make the reed 11 of the push rod 6 aligning microswitches 7 of magnetic controller 13.Draw lead 8 in the lower end of lid 9.
The course of work of the present utility model is: marquis when water table ratio is fuller in the water tank, floating drum 1 is put, the magnet 15 of floating drum 1 bottom is in the effect in magnetic field, make the magnet 14 of magnetic controller 13 promote 6 times making leaf springs 11 of push rod, connecting terminal 10, connect the heating tube power supply, make electric heater work.When water level in the water tank dropped to a certain degree, floating drum 1 fell down to be lying in the water tank, and the push rod 6 of magnetic controller 13 is lifted under the effect of stage clip 12, and reed 11 separates with contact 10, and 7 of microswitches are in off-state, cut off heater power source.Even send the electric heater work of also can't switching on once more.
