Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description.
The hand electric device of measurement dump internal temperature provided by the invention, as shown in Fig. 1 ~ 3, including sleeve 1, set
Cylinder 1 is a hollow metal steel pipe, and pipe diameter size meets one hand of adult and easily holds, and setting can be along set inside sleeve 1
The mobile worm screw 2 of 1 length direction of cylinder, the head of worm screw 2 are arranged to the pointed shape of normal drill bit, and taper inner is embedded with thermometric member
Part 3, temperature element 3 are existing element, such as thermal resistance.2 body interior of worm screw is in addition to pre-buried temperature element 3, also pre-buried connection
The insulated cable of temperature element 3.Rectangular aperture is arranged close on tip position side wall in one end of sleeve 1, is internally provided with turbine 5
12 side of spiral case also be provided with an equal amount of rectangular aperture, the rectangular aperture of sleeve 1 and the rectangular aperture of spiral case 12 weld and connect
It connects.12 upper surface of spiral case and lower end surface contour line are circle, and spiral case 12 is internally provided with turbine 5, and turbine 5 is the toothed gold in outer ring
Belonging to disk, turbine 5 rotates in spiral case 12 by axis of the line in 12 upper surface of spiral case and the lower end surface center of circle, meanwhile, the tooth of turbine 5
With the screw serrated form of worm screw 2 at engaging, worm screw 2 can be driven to move back and forth along 1 direction of sleeve by the positive and negative rotation of turbine 5.
Since the present invention controls the depth of temperature element 3 by the way of turbine and worm, only this is filled compared to artificial insertion, power
Foot, can according to the length of worm screw determine insertion dump depth, such as can it is deep enough measurement dump inside 1 ~ 4 meter temperature and
Heap is not influenced and takes coal operation, and can be easily removed and.
Temperature element 3 is drawn out to the tail portion of worm screw 2 by pre-buried insulated cable, and connects and show by using signal wire 9
Show instrument 10.Display instrument 10 receives the temperature signal that temperature element 3 transmits, by temperature display to face after internal driving circuit
On a fritter liquid crystal display on plate.Signal wire 9 is spring wire, is spring shape under conventional sense, can follow worm screw
It moves and stretches or shrink.Display instrument 10 is by its internal storage battery power supply.
Turbine 5 of the invention is driven by direct current generator 11 carries out positive and negative rotation, and then drives the worm screw 2 engaged with turbine 5
It moves back and forth.As the equipment of hand-held, small-sized direct current generator 11 can be on hand electric device directly through the invention
The battery of assembly is powered.
Direct current generator 11 drives work by controller 7, and equally by storage battery power supply, controller 7 can be used controller 7
Existing controller, such as the existing CPU or single-chip microcontroller that can be realized present invention control motor positive and inverse.In controller 7
Portion is provided with battery, and battery is the drive circuitry of direct current generator.
As shown in Figure 1, being fixedly installed fixed engagement tooth 4 on the inner wall of 1 front of sleeve, the fixed engagement tooth 4 is in worm screw 2
On the movement line of tooth socket, and with the slot form of worm screw 2 cooperate, the cooperation refer to it is identical as the slot form of worm screw 2, or
It is slightly less than slot form, for during retraction, fixed engagement tooth 4 to bring the tooth socket curved surface of worm screw 2 up in worm screw 2
Coal dust is forced down, and prevents coal dust from largely entering sleeve inner, blocks the round-trip of worm screw 2.
The tail portion of worm screw 2 is provided with empennage, on direction as shown in Figure 1, is fixedly installed on the inner wall of 1 middle and lower part of sleeve
Limiting tooth 8.Empennage limits stretching displacement of the worm screw 2 inside sleeve 1 after colliding with limiting tooth 8.As a kind of reality
Mode is applied, when 2 length of worm screw is 3.5m or so, limiting tooth 8 is 0.5m or so, worm screw 2 apart from the distance that 1 lower end of sleeve exports
The length of extended 1 lower end of sleeve outlet is 3m or so.
As shown in figure 3, for from 1 bottom worm screw of sleeve, 2 outlet port to the side view in terms of 1 top-direction of sleeve, sleeve 1 with
Spiral case 12 is communicated by opening rectangular aperture welding, the two inner space in advance, and display instrument 10 and controller 7 are all by metab
It is welded direct to 1 outer surface of sleeve.
When the device of the invention makes, spiral case 12 is in the position close to the outlet of 1 lower part worm screw 2 of sleeve, it is ensured that worm screw
Stretch out the effective length longest of sleeve 1.To guarantee that the effective length of worm for going deep into dump is the length needed, the length of sleeve 1
Needing to be longer than the length of worm screw 2, such as the length of worm screw is 1 ~ 4 meter, sleeve 1 needs about 2 ~ 5 meters, for the ease of carrying, optional 3
The sleeve of rice or so, the effective length into the worm screw of dump is about 0 ~ 2.5 meter.
The device of the invention is in use, coal surface, holding sleeve 1 and coal are withstood in 1 bottom of sleeve by device user of service
Layer surface is vertical, then starts motor and rotates forward, worm screw 2 is squeezed into coal seam depths.In view of worm screw 2 is squeezed into inside dump along straight line
When, coal and the meeting frictional heat generation of worm screw 2, the temperature after measure after the heat diffusion because of friction generation are only the temperature to be surveyed,
Therefore worm screw 2 is squeezed into inside dump after a few minutes, and the temperature that display instrument 10 is shown is the dump internal temperature to be surveyed.Fig. 2 is
Device under thermometric state.
After thermometry readings, direct current generator 11 is controlled using controller 7 and is inverted, is fully retracted worm screw 2 inside sleeve 1
After stop motor.For worm screw 2 during retraction, fixed engagement tooth 4 forces down the coal dust that 2 curved surface of worm screw is brought up.
In the description of this specification, particular features, structures, materials, or characteristics can be real in any one or more
Applying can be combined in any suitable manner in example or example.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those skilled in the art the invention discloses in the range of, the variation or replacement that can be readily occurred in should all be covered
Within the scope of the present invention.
