Description

Technical Field

[0001] This utility model relates to the field of turnout snow removal technology, specifically a pneumatic jet railway turnout snow removal device. Background Technology

[0002] Railway turnouts are key pieces of equipment in a track system, used to guide trains from one track to another, enabling flexible switching and crossing of lines. They consist of switches (point rail, stock rail), frogs (frog rail, wing rail), connecting parts, and sleepers, and change the train's direction of travel through mechanical or electric control of the point rail movement. To ensure safety during track switching, snow accumulation on the turnouts needs to be cleared.

[0003] In the prior art, the authorized announcement number CN206233169U discloses a snow removal machine for railway turnouts, including an air supply pipe, at least one blower pipe disposed on the air supply pipe, a fan disposed at one end of the air supply pipe, and a signal receiver connected to the fan. The blower pipe is disposed below the air supply pipe, a solar panel is disposed on the surface of the air supply pipe, and a battery is disposed on the air supply pipe. The battery is connected to the solar panel and the fan.

[0004] In the aforementioned device, an airflow is generated using a fan to blow snow off the tracks from the turnout, thus achieving the effect of snow removal. However, because the airflow generated by the fan is relatively slow, it is difficult to completely blow the snow off the tracks in actual operation, resulting in incomplete cleaning. Therefore, a pneumatic jetting snow removal device for railway turnouts is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a pneumatic jetting snow removal device for railway turnouts to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic jetting snow removal device for railway turnouts, comprising a cabinet, a cabinet door installed on the cabinet, a support leg fixedly installed at the bottom of the cabinet, a snow removal mechanism installed on the cabinet, the snow removal mechanism comprising a compressor and a gas tank fixedly installed inside the cabinet, an air outlet pipe connected to the gas tank, a solenoid valve installed on the air outlet pipe, nozzles spaced apart on the air outlet pipe, and a drainage mechanism fixedly installed at the bottom of the gas tank.

[0007] Preferably, the snow removal mechanism further includes an air inlet pipe fixedly installed between the compressor and the air tank, and both the compressor and the air tank are fixedly installed with legs.

[0008] Preferably, the legs are connected to bolts, and the legs are all fixedly installed on the inner wall of the cabinet by bolts.

[0009] Preferably, both the compressor and the gas tank are fixedly installed in the cabinet using brackets, with one end of the air inlet pipe connected to the compressor and the other end connected to the gas tank.

[0010] Preferably, the drainage mechanism includes a drain outlet fixedly installed at the bottom of the gas tank and a metal pipe fixedly installed at the bottom of the cabinet, with the metal pipe and the drain outlet aligned vertically. A positioning seat is fixedly installed at the upper end of the drain outlet, an electromagnet is fixedly installed on the positioning seat, and a spring is installed inside the positioning seat. A sealing plug is movably installed on the drain outlet, an armature block is fixedly installed at the upper end of the sealing plug, and a toothed rod is fixedly installed at the bottom of the sealing plug. A heating coil is sleeved on the metal pipe, and a rotary switch is connected to the heating coil and fixedly installed on the metal pipe. A small gear is fixedly installed on the input end of the rotary switch, and the small gear meshes with the toothed rod.

[0011] Preferably, the cabinet has an installation port at the bottom, through which the metal tube is installed on the cabinet.

[0012] Preferably, one end of the spring is connected to the positioning seat, and the other end of the spring is connected to the sealing plug. The electromagnet is installed above the sealing plug through the positioning seat, and the electromagnet and the armature block on the sealing plug are vertically aligned.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, after the compressor is started, it compresses and stores air in an air tank. When the control solenoid valve is opened, the compressed air in the air tank is ejected at high speed through a nozzle to remove snow from the switch. The high airflow velocity from the nozzle enhances the cleaning effect.

[0015] 2. When the electromagnet is activated, the magnetic field it generates attracts the armature block, causing the sealing plug to move upwards. This upward movement of the sealing plug disengages it from the drain outlet, allowing water accumulated in the gas tank to drain through. Simultaneously, the upward movement of the sealing plug also drives the toothed rod upwards, which in turn causes the pinion to rotate. The rotation of the pinion drives the rotary switch, activating the heating coil and heating the metal tube to maintain a high internal temperature, preventing icing at the drain outlet and ensuring the proper functioning of the drainage system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a pneumatic jetting railway turnout snow removal device, including a cabinet 1, a cabinet door 2 installed on the cabinet 1, a support leg 3 fixedly installed at the bottom of the cabinet 1, a snow removal mechanism 4 installed on the cabinet 1, and a drainage mechanism 5 fixedly installed at the bottom of the air tank 403. The snow removal mechanism 4 can clear the snow accumulated on the turnout, and the drainage mechanism 5 can prevent the drain outlet 504 on the air tank 403 from freezing.

[0023] like Figure 2 and Figure 3 As shown, the snow removal mechanism 4 includes a compressor 401 and an air tank 403 fixedly installed inside the cabinet 1. An air outlet pipe 405 is connected to the air tank 403, a solenoid valve 406 is installed on the air outlet pipe 405, and nozzles 404 are installed at intervals on the air outlet pipe 405. The snow removal mechanism 4 also includes an air inlet pipe 402 fixedly installed between the compressor 401 and the air tank 403. Both the compressor 401 and the air tank 403 are fixedly installed with legs 407, and bolts are connected to the legs 407. The legs 407 are all fixedly installed on the inner wall of the cabinet 1 by bolts.

[0024] Specifically, after compressor 401 is started, the device begins its main function: drawing in and compressing ambient air, then storing the compressed air in air tank 403. When snow removal is required, solenoid valve 406 is activated, opening the compressed air in air tank 403. Under pressure, the compressed air is then ejected at high speed through nozzle 404. This high-speed airflow effectively blows snow accumulated on the switches away from the tracks, ensuring the switches' normal operation. Because the airflow from nozzle 404 is extremely fast, it provides superior cleaning performance, rapidly removing snow and ensuring smooth and safe railway traffic.

[0025] like Figure 2 and Figure 4 As shown, the drainage mechanism 5 includes a drain outlet 504 fixedly installed at the bottom of the gas tank 403 and a metal pipe 509 fixedly installed at the bottom of the cabinet 1, with the metal pipe 509 and the drain outlet 504 vertically aligned. A positioning seat 507 is fixedly installed at the upper end of the drain outlet 504, an electromagnet 501 is fixedly installed on the positioning seat 507, and a spring 502 is installed inside the positioning seat 507. A sealing plug 503 is movably installed on the drain outlet 504, and an armature is fixedly installed at the upper end of the sealing plug 503. Block 508, sealing plug 503 has a toothed rod 505 fixedly installed at the bottom, a heating coil 511 is sleeved on the metal tube 509, a rotary switch 510 is connected to the heating coil 511 and the rotary switch 510 is fixedly installed on the metal tube 509, a pinion 506 is fixedly installed on the input end of the rotary switch 510 and the pinion 506 meshes with the toothed rod 505, an installation port is opened at the bottom of the cabinet 1 and the metal tube 509 is installed on the cabinet 1 through the installation port.

[0026] Specifically, when electromagnet 501 is activated, it attracts armature block 508. This action causes sealing plug 503 to move upward, thus moving away from drain outlet 504. As sealing plug 503 rises, water accumulated in gas tank 403 can be smoothly drained through drain outlet 504. Furthermore, the upward movement of sealing plug 503 also drives toothed rod 505 to move upward. The rise of toothed rod 505 drives pinion 506 to rotate. During rotation, pinion 506 further rotates knob switch 510. Rotation of knob switch 510 activates heating coil 511, causing it to start working. Heating coil 511 heats metal tube 509, ensuring that the inside of metal tube 509 remains at a high temperature. This high temperature is crucial for preventing freezing at drain outlet 504, thus ensuring smooth and effective drainage.

[0027] Working principle: When in use, first install the nozzle 404 in the gap between the main rail and the switch rail of the turnout. Then, start the compressor 401. After starting the compressor 401, the air will be compressed into the air tank 403 for storage. When the control solenoid valve 406 is opened, the compressed air in the air tank 403 will be sprayed out at high speed through the nozzle 404, thereby blowing away the snow on the turnout. The airflow sprayed by the nozzle 404 is faster and the cleaning effect is better. When a large amount of water accumulates in the gas tank 403, the electromagnet 501 can be activated. After activation, the electromagnet 501 will attract the armature block 508, causing the sealing plug 503 to move upward. After the sealing plug 503 moves upward, it will move away from the drain port 504, allowing the water in the gas tank 403 to be discharged through the drain port 504. When the sealing plug 503 moves upward, it will also drive the toothed rod 505 to move upward. After the toothed rod 505 moves upward, it will drive the pinion 506 to rotate. When the pinion 506 rotates, it will turn the knob switch 510, causing the heating coil 511 to work and heat the metal tube 509. This keeps the inside of the metal tube 509 at a high temperature, preventing freezing at the drain port 504 and ensuring the drainage effect.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
