Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Fig. 1, shown in 2, a kind of deep well submerged pump depth of water detection means, including：Device case 1, it is to follow diving outside it Pump enters the pipe of well depths, and inside is the cavity 2 sealed under atmospheric pressure state；First wire 3, it prolongs from the pipe bottom Drawn again from top after extending top, and follow the part of the pipe extension all embedded in the inwall of described device housing 1；And Second wire 4, it extends to behind top from the pipe bottom and drawn again from top, and follows the part of the pipe extension complete Portion is embedded on the first wire 3 and the centrosymmetric position of the pipe；Exist respectively on the wire 4 of first wire 3 and second It is spaced and fixes several first resistor block 5 and second resistance block 6 on equal position respectively；And first resistor block 5 and second Gap is provided between resistance bolck 6；Described device housing 1 is additionally provided with the connecting portion 7 for being fixed on the immersible pump under deep-well. The utility model before the use, first respectively contacts first wire 3, the second wire 4 with power positive cathode, and in circuit In also concatenate ammeter.Because inside is the hermetic seal cavity 2 under atmospheric pressure state, when so there is no pressure in the external world, meeting Air pressure inside cavity 2 struts, and then to generate gap between first resistor block 5 and second resistance block 6, such first Resistance bolck 5 and second resistance block 6 are achieved that the separation of open circuit, while the first wire 3 and the second wire 4 and independent open circuit State.

After the utility model one end is fixed on immersible pump again, then after immersible pump is gradually put into deep-well, then deep-well Interior water can slowly extrude the device case 1 contacted with water, the gap between such second resistance block 5 and second resistance block 6, just Can be because be squeezed contact, and then realize the first wire 3 and the contact of the second wire 4 turns on, due to first resistor block 5 and the Two resistance bolcks 6 are entirely resistance value identical conductor, and are much organized between first resistor block 5 and second resistance block 6 also only etc. Spacing is placed, therefore according to the calculation formula of parallel resistanceIt can learn：Parallel circuit Middle R_AlwaysNumerical value, while the electric current for only needing detection to change is vertical, it is possible to show that now immersible pump is placed to relative to well water Underwater is how many depth, to the end in the length plus immersible pump, just can know that more accurate depth.

Further, it is embedded in the first wire 3 of the inwall of described device housing 1, the outer surface of the second wire 4 also prevents electricity Flow the insulating barrier of electric leakage.When manufacture device body 1, it is insulating materials that material, which is preferably selected, but for greater safety and Current values accurately can be detected, it is necessary to install the insulating barrier for preventing current leakage, so prevent from device body 1 with The situation for scratching and causing electric leakage can be produced when with immersible pump underwater.

Further, the inside of connecting portion 7 includes：It is easy to the through hole being connected with the immersible pump under deep-well.In order to more can Accurately detect, it is necessary to the bottom of device body 1 is connected by dismountable connected mode with immersible pump, followed by diving Pump sinks to underground.

Further, the clearance distance is in the range of 2 to 3 millimeters.According to the caliber and resistance of different device bodies 1 The size of block, after test of many times, clearance distance is selected to prevent first resistor block 5 and the in 2 to 3 millimeters of scopes Two resistance bolcks 6 contact by mistake, at the same the external world somewhat have hydraulic pressure in the case of, can also cause the two contact well so that electric current Conducting.

Further, the also fixed graduated scale 8 in outer surface of described device housing 1 is followed.In actual use, this reality is used It can determine that immersible pump is placed into underwater more deep depth very well with new, but be laid down for immersible pump more relative to ground Deep underground, but without good scale, therefore graduated scale 8 is added in the outer surface of device case 1, so with immersible pump The device body 1 being placed into, by reading the scale of outer surface, just immersible pump can be determined relative to the how deep of ground well Depth.

Further, the thinning formation kink of thickness on the device case 1 among 3 and second wire of the first wire 4 11.In reality in use, in order to realize that first resistor block 5 and resistance bolck 6 contact, it is necessary to need certain hydraulic pressure, still When device body 1 just contacts the water surface, because the water layer of the water surface is shallower, cause first resistor block 5 and second resistance block 6 It less can easily contact, can thus cause detection error, in order to obtain under conditions of somewhat having hydraulic pressure, it is possible to realize One resistance bolck 5 and the situation of the can of second resistance block 6 contact, therefore by changing the outer wall thickness of device body 1, so exist In the case of somewhat having hydraulic pressure, whole device body 1 will easily be bent under hydraulic pressure, and then obtain first resistor block 5 and second resistance block 6 contact, improve the sensitivity of whole device.

Operation principle：The depth detection of water is transformed into electric signal, led to by the utility model by the resistance bolck of fixed range Cross the depth that detection electric signal is obtained with accurate underwater.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
