Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the present invention:
The invention discloses a kind of earth resistance tester protecting box, for containing earth resistance tester, present invention tool
There is coiling apparatus, also can be suitably used for other instruments for needing to carry out retractable cable what is specifically applied.Specific implementation of the invention
Under such as:
Protecting box of the invention includes box body 1, and the box body 1 generally carries out according to the shape of earth resistance tester specific
Setting, in this embodiment box body 1 be upper end opening rectangular housing, box body 1 open end be arranged for box body to be sealed
The box body cover board 8 closed, specific structure is as shown in Figure 1.
Coiling apparatus is set in 1 side of box body, for receiving to a large amount of ground line that earth resistance tester uses
Receive arrangement.Coiling apparatus in the present invention mainly carries out retractable cable by reel 3.Reel 3 is at work around certainly
Body axis are rotated, and are neatly stored in the fixed guarantee ground line of off working state.In the specific implementation process may be used
To drive reel rotation in setting servo motor, to realize rotation and fixed two states.
Coiling apparatus can also mechanically realize that specific embodiment is as follows: coiling apparatus in the present invention
Including the spool 2 and reel 3 fixed with box body 1, the circular hole that reel 3 passed through axis is sleeved on spool 2,
The pivoting on spool 2 of reel 3.The setting elastic cap 4 of 2 outer end of spool come control reel 3 rotation and
It is fixed.Spool 2 includes integrally formed optical axis section 2-1 and thread segment 2-2, and elastic cap 4 includes integrally formed thread barrel 4-1
With crown 4-2.Thread barrel 4-1 is used cooperatively with thread segment 2-2, and the preferential length by thread barrel 4-1 is greater than the spiral shell of spool 2
The length of line section 2-2, the width of reel 3 is consistent with the length of optical axis section 2-1, and specific structure is as shown in Figure 2.It in this way can be with
By elastic cap 4 to the deeper precession of the inner end of spool 2, i.e., when thread segment 2-2 is fully screwed into thread barrel 4-1, continue turn
Elastic cap 4, so that the end of the thread barrel 4-1 of elastic cap 4 is compressed reel 3 keeps reel 3 fixed.Needing retractable cable
When, elastic cap 4 is unclamped, reel 3 can be freely rotated at this time.Crank is also provided on reel 3.
Coiling apparatus further includes pressure-ray film 5 in the specific implementation process, and 5 top of pressure-ray film and 1 side wall of box body are solid
Fixed, bottom end is protruded into the wire casing of reel 3, and specific structure is as shown in figure 1, figure 3 and figure 4.Pressure-ray film 5 is flexible hard
Sheet body, specifically can be iron plate, and pressure-ray film 5 is further ensured during retractable cable and is grounded under off working state
It will not be at random.
The coiling apparatus of the embodiment of the present invention is preferentially arranged two, and two coiling apparatus are particularly separately positioned on box
The two sides of body 1.General earth resistance tester needs three piece-root grafting ground wires, therefore generally requires three reels of setting.Wherein
One 3-1 of reel is arranged in one coiling apparatus, and integrally formed two 3-2 of reel and reel three is arranged in another coiling apparatus
3-3.Since the length of three piece-root grafting ground wires generally can be different, therefore preferentially by one 3-1 of reel, two 3-2 of reel, reel
The wheel shaft of three 3-3 is set as that diameter is not identical, particularly by the wheel of one 3-1 of reel, two 3-2 of reel, three 3-3 of reel
The ratio between shaft diameter is set as 1:2:4, such as the wheel shaft diameter of one 3-1 of reel is 40mm, the wheel shaft diameter of two 3-2 of reel is
80mm, three 3-3 of reel wheel shaft diameter be 160mm.The neat folding and unfolding of different length ground line may be implemented in this way.Meanwhile
Consistent form can also be set by the wheel shaft diameter of one 3-1 of reel, two 3-2 of reel, three 3-3 of reel.
The grounding rod slot 6 for storing grounding rod is inclined to the back side of box body 1, preferentially by grounding rod in the present invention
Angle where slot 6 and 1 bottom surface of box body between plane is 15 °~20 °.Grounding rod slot 6 specifically can be semicircular
Shell, the semicircular shell are buckled in the back side of box body 1.Directly it is inserted into grounding rod slot 6 when storing grounding rod.
