Description
Technical field
The utility model relates to a kind of electric switch machine structure field, relates in particular to the moistureproof hole of a kind of switch machine setting device.
Background technology
Switch machine is a kind of equipment conventional on railway, has following three basic function: supervision and the expression of track switch conversion, switch locking, track switch state.Current domestic switch machine is produced and has all been reached complete independent intellectual property right, and product is except general speed, high speed railway at home, and subterranean railway is widely used, and is also sold abroad, and especially in South East Asia and west Asia, has a lot of application.
Certain type electric switch machine is to need for high-speed railway switch conversion the novel switch machine of researching and developing, there is higher driving efficiency and the reliability of Geng Gao, it uses region extensive, comprise various places, China north and south, South East Asia and Middle East, due to the difference of each department climatic conditions, equipment is also faced with different severe working environments, the factor that affects its normal work comprises: day and night temperature is large, air humidity is very big or minimum, ambient temperature is low etc., these problems all make the switch machine that can normally work in laboratory on track switch, occur variety of issue: the throw rod of switch machine is released to draw in to move damp air is drawn into equipment inner chamber, night, temperature reduced, after wet air is cooling, separate out drop, when serious, can there is frost, these drops and ice crystal are attached on switch machine inner body, can cause metallic contact to accelerate get rusty and accelerate the corrosion of inner plastics contact, there is Signs of Mould in junction block, this all can cause circuit to break down, even the existence of drop directly causes internal short-circuit, bring grave danger to railway security.
Based on above reason, switch machine internal cavities to put damp problem particularly important.Switch machine is before considered about the design of moistureproof aspect, is at cover sidewall, along perforate in throw rod direction, installs damp-proof device additional, and two Kong Jun are positioned at the centre of sidewall.But through simulation analysis, the efficiency of this kind of perforate mode is not high, and is difficult to meet the moistureproof requirement of whole internal cavities, therefore, for the protection against the tide of switch machine, need the method for arranging in better moistureproof hole.
Summary of the invention
The purpose of this utility model is to provide the moistureproof hole of a kind of switch machine setting device that moisture effect is good.
The technical solution of the utility model is that the moistureproof hole of a kind of switch machine setting device, is characterized in that: on the contact wall of switch machine cover, have the first moistureproof hole; On the motor wall of switch machine cover, there is the second moistureproof hole.
The location dimension in the first moistureproof hole is: the location dimension on the first moistureproof Kong Kong center and cover top is 45mm.The location dimension of the first moistureproof Kong Kong center and center of symmetry is 122.5mm.
The location dimension in the second moistureproof hole is: the location dimension on the second moistureproof Kong Kong center and cover top is 40mm, and the second moistureproof Kong Kong center and center of symmetry location dimension are 142.5mm.
The utility model has the advantages that: do not changing under the condition of original moistureproof hole dimension size and its damp-proof device, by the position in moistureproof hole by being improved to diagonal line on same straight line, and change the cover sidewall of arranging moistureproof hole, by the position in moistureproof hole on switch machine before adjusting, meet the moistureproof requirement of whole internal cavities, the efficiency of this kind of perforate mode is high, and moisture effect is good.
Below in conjunction with embodiment accompanying drawing, the utility model is described further.

Fig. 2 is that schematic diagram is arranged in the moistureproof hole of the utility model embodiment cover motor wall;
Fig. 3 is bore size and location schematic diagram on contact wall;
Fig. 4 is bore size and location schematic diagram on motor wall.
In figure, 1, the first moistureproof hole; 2, the second moistureproof hole; 3, contact wall; 4, motor wall.5, switch machine cover; 6, center of symmetry; 7, cover top.
Detailed description of the invention
Referring to Fig. 1, the moistureproof hole of a kind of switch machine setting device has the first moistureproof hole 1 on the contact wall 3 of switch machine cover 5.
Referring to Fig. 2, on the motor wall 4 of switch machine cover 5, there is the second moistureproof hole 2.
Referring to Fig. 3, the location dimension in the first moistureproof hole 1 is: the location dimension on the first 1 Kong center, moistureproof hole and cover top 7 is 45mm.The location dimension of the first 1 Kong center, moistureproof hole and center of symmetry 6 is 122.5mm.
Referring to Fig. 4, the location dimension in the second moistureproof hole 2 is: the location dimension on the second 2 Kong centers, moistureproof hole and cover top 7 is 40mm, and the second 2 Kong centers, moistureproof hole and center of symmetry 6 location dimensions are 142.5mm.
Experimental result:
In the utility model, under equal boundary condition, (initial condition (IC) is inner filling water steam, at the uniform velocity 10m/s of dry air flow field around, direction is vertical with perforate face), use finite element software FLUENT to carry out analog simulation to existing moistureproof hole method for arranging and moistureproof hole of the present utility model method for arranging, obtain result as shown in table 1.
Table 1 analog simulation result
As can be seen from Table 1, the moistureproof hole set-up mode that the utility model provides and existing moistureproof hole are arranged under equal load-up condition, the Peak Flow Rate of importing and exporting all increases a lot, the aqueous vapor volume fraction of switch machine inner chamber was reduced to for 10% time used by initial 100%, had also reduced 10%.In addition, the moistureproof hole setting position proposing in the utility model has been avoided inner part position, this is to cause importing and exporting the major cause that flow velocity increases, and it is diagonal line that moistureproof hole site is set in the utility model, the mobile scope of inner air is larger, can be dried better moistureproof to whole internal cavities.Below all illustrate that the moistureproof hole set-up mode proposing in the utility model can, better to forming the convection current of air, in the case of the damp-proof device that does not change hole dimension and install additional, can more effectively reduce the inner excessive air humidity that may occur.
