Abstract
Description
Technical Field
[0001] The utility model relates to a dehumidification tool for a railway turnout switch machine, belonging to the technical field of railway switch machine maintenance tools. Background Art
[0002] Railway turnout switch is an important signal infrastructure equipment used to reliably change the position of turnouts, change the direction of turnout opening, lock the turnout point rail, and reflect the position of the point rail. It can well ensure driving safety. The moisture inside the turnout switch will cause rust on the shift contactor, dynamic and static contacts, springs and other components; accelerate the aging of electrical components; cause changes in mechanical and electrical characteristics, and cause turnout switch failures, which will endanger driving safety in severe cases. However, it is difficult to eliminate the moisture that has always existed inside the turnout switch through daily maintenance. Therefore, it is very necessary to know how to eliminate the moisture inside the turnout switch. Utility Model Content
[0003] The utility model aims to provide a dehumidification tool for a railway turnout switch machine, which can absorb moisture inside the turnout switch machine and discharge it outside the turnout switch machine, thereby solving the problems existing in the background technology.
[0004] The technical solution of the utility model is:
[0005] A dehumidification tool for a railway turnout switch comprises a protective cover, a dehumidification bin, a screen, a water collecting bin and a drain pipe. The dehumidification bin is located above the water collecting bin, the protective cover is fixed on the dehumidification bin, the screen is arranged between the dehumidification bin and the water collecting bin, and a drain pipe is arranged below the water collecting bin.
[0006] The dehumidification bin is filled with dehumidification particles, and the dehumidification particles are covered with one-way breathable paper.
[0007] The size of the sieve holes matches the size of the dehumidification particles filled in the dehumidification bin.
[0008] The drainage pipe is connected with the drainage hole of the turnout machine through a sealing ring.
[0009] A check valve is arranged on the drain pipe.
[0010] The beneficial effects of the utility model are: simple structure, easy to use, can absorb moisture inside the switch machine and discharge it outside the turnout switch machine, prevent the internal shift contactor, dynamic and static contacts, springs and other components of the turnout switch machine from rusting, reduce the aging of electrical components, and ensure the operational stability of the switch machine. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is an exploded view of the utility model;
[0012] Figure 2 This is a schematic diagram of the utility model after installation:
[0013] The markings in the figure are as follows: protective cover 1, dehumidification chamber 2, screen 3, water collection chamber 4, drain pipe 5, check valve 6, sealing ring 7. DETAILED DESCRIPTION
[0014] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0015] See attached Figure 1 , 2 A dehumidification tool for a railway turnout switch includes a protective cover 1, a dehumidification bin 2, a screen 3, a water collecting bin 4 and a drain pipe 5. The dehumidification bin 2 is located above the water collecting bin 4, the protective cover 1 is fixed on the dehumidification bin 2, the screen 3 is arranged between the dehumidification bin 2 and the water collecting bin 4, and a drain pipe 5 is arranged below the water collecting bin 4.
[0016] In this embodiment, refer to the attached Figure 1 , 2 The dehumidification tool of the railway turnout switch machine includes a protective cover 1, a dehumidification chamber 2, a screen 3, a water collection chamber 4, a drain pipe 5, a check valve 6 and a sealing ring 7, wherein:
[0017] The dehumidification chamber 2 is filled with dehumidification particles, which are covered with one-way breathable paper to protect the dehumidification particles in the dehumidification chamber 2 from contacting with moisture in the air and effectively absorbing moisture in the air.
[0018] The protective cover 1 is fixed above the dehumidification chamber 2 .
[0019] The screen 3 is arranged between the dehumidification bin 2 and the water collection bin 4 to act as a partition to prevent the dehumidification particles in the dehumidification bin 2 from entering the water collection bin 4. The moisture absorbed by the dehumidification bin 2 can flow into the water collection bin 4 through the screen 3.
[0020] The upper end of the drain pipe 5 is connected to the water collecting bin 4, and the lower end of the drain pipe 5 is connected to the drain hole of the turnout switch machine through the sealing ring 7. The check valve 6 is installed in the middle of the drain pipe 5 to prevent the external water of the turnout switch machine from flowing back into the turnout switch machine.
[0021] The dehumidification chamber 2 absorbs moisture in the air inside the turnout switch machine and discharges it outside the turnout switch machine through the water collecting chamber 4, the check valve 6 and the drain pipe 5. The protective cover 1 protects the dehumidification tool of the railway turnout switch machine, the screen 3 prevents the dehumidification particles from falling into the water collecting chamber 4, and the check valve 6 and the sealing ring 7 prevent the water outside the turnout switch machine from flowing back.
