Description

TECHNICAL FIELD

[0001] The application relates to a high-temperature protection device for a train heater and a cooling method. BACKGROUND

[0002] During the running of a train, the temperature needs to be adjusted in time due to a large temperature difference between the inside and the outside, and thus a train heater needs to be used. When the train heater works, the train heater can cooperate with an air conditioning system in the train to automatically adjust the temperature in the train, so that the temperature in the train is stable, and the comfort of passengers is improved. The train heater has the advantages of high efficiency and stability. When the train heater works, electric energy is converted into heat energy. If the heat cannot be dissipated in time, the temperature of the heating element will continue to rise. When the train heater is in a high-temperature state for a long time, the electronic devices inside the train heater will be affected. Therefore, a high-temperature protection device for the train heater needs to be used in cooperation. After the high-temperature protection device for the train heater is used for a long time, the heat of the high-temperature protection device itself will also rise. For example, a train air conditioner electric heater over-temperature protection device (application number 202223035987.X) is convenient for installation of the electric heater, and has the installation of a temperature sensor. The temperature sensor can monitor the temperature of the electric heater in real time. When the temperature is too high, the electric heater is automatically cooled or powered off, so that the normal use of the electric heater is ensured, and the practicability of the device is improved. Another example is a temperature protection device for a train electric heater (application number 201520308216.4). A high-power temperature fuse is connected in series in an electric heating main loop, and serves as a temperature secondary protection device for the electric heater. When the temperature control loop of the electric heater fails, the temperature secondary protection device acts when the temperature of the electric heater reaches a limited temperature point, and directly cuts off the electric heating main loop. The device is simple, easy to operate, and has a remarkable effect. The device solves the problem of failure of the temperature control loop of the electric heater, avoids non-normal shutdown of the train unit caused by the problem of the electric heater, and more importantly, eliminates the safety accident hidden danger caused by overheating of the electric heater.

[0003] After the high-temperature protection device for the train heater works for a long time, the heat of the high-temperature protection device itself will rise. The device in the above application does not have a structure for self-cooling of the high-temperature protection device during use. Therefore, the subsequent use of the high-temperature protection device and the subsequent work of the train heater will be affected, and unnecessary troubles are brought to the work of the train heater.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The present invention provides the following technical solution: a high-temperature protection device for a high-speed train heater.

[0039] Example 1: The water tank 1, water pump 3, and hose 5 are used to cool the train heater. A water deflector 17 is also provided to cool the water tank 1. Figures 1-6 As shown, the system includes a water tank 1, a working pipe 4 fixedly connected to the left side of the water tank 1, a tank cover 2 connected to the upper surface of the water tank 1, a water pump 3 fixedly connected to the right side of the water tank 1, and a flexible hose 5 fixedly connected to the surface of the working pipe 4. When working, the flexible hose 5 is wrapped around and attached to the surface of the train heater to cool the train heater with water, and the end of the flexible hose 5 is fixedly connected to the right side of the water pump 3. An inner plate 6 is fixedly connected to the inner wall of the water tank 1, and a connecting shaft 7 is rotatably arranged inside the inner plate 6.

A water-dispensing plate 17 is fixedly connected to the surface of the slider 13.

[0040] The inside of the water tank 1 is movably provided with a stress plate 9; the reciprocating mechanism comprises a limiting rod 11 fixedly connected to the inner wall of the water tank 1, the surface of the limiting rod 11 is slidably provided with a sliding block 13, the upper surface of the sliding block 13 is fixedly connected with an upper connecting block 14, the surface of the limiting rod 11 is convex, the lower surface of the stress plate 9 is fixedly connected with a lower connecting block 15, the inside of the lower connecting block 15 is movably provided with a push rod 16, the other side of the push rod 16 is movably connected with the upper connecting block 14, the surface of the connecting shaft 7 is fixedly connected with a cam 10, the surface of the sliding block 13 is fixedly connected with a connecting spring 12 which plays a role of elastic reset, the other side of the connecting spring 12 is fixedly connected with the inner wall of the water tank 1, the surface of the limiting rod 11 is convex, the sliding blocks 13 are symmetrically distributed on the two sides of the water tank 1, the surface of the water deflector 17 is provided with through holes 18 which are equidistantly distributed on the surface of the water deflector 17.

[0041] In work, the hose 5 is wound and attached to the outer surface of the motor train heater, when cooling, the water pump 3 is started, at this time, the water flow in the water tank 1 circulates in the water tank 1 and the hose 5, which plays a role of water cooling for the motor train heater, and in the process of water flow circulation, the water wheel 8 is impacted, at this time, the connecting shaft 7 rotates in the inside of the inner plate 6 under the action of the water wheel 8, and then the cam 10 intermittently pushes the stress plate 9, when the stress plate 9 is pushed, the stress plate 9 drives the sliding block 13 to move to the direction of pressing the connecting spring 12 through the lower connecting block 15, the push rod 16 and the upper connecting block 14 (the limiting rod 11 makes the sliding block 13 only move in the horizontal direction), the above process is repeated, the sliding block 13 moves in the horizontal direction, when the sliding block 13 moves, the water deflector 17 moves synchronously, and then the water deflector 17 and the through holes 18 play a role of shaking the water flow, so that the heat in the water flow is quickly discharged, and then the water flow can better cool the motor train heater, and the working efficiency is improved.

[0042] Example two: different from example one, the movable plate 21, the stand column 22 and the convex block 23 are arranged, which play a role of side shaking of the water flow, as shown in the figure, Figure 7 The inside of the water tank 1 is connected with the movable plate 21 through the lifting mechanism, the lifting mechanism comprises an auxiliary rod 19 fixedly connected to the upper surface of the sliding block 13, the front view of the auxiliary rod 19 is a reverse "L" structure, the lower surface of the inner plate 6 is fixedly connected with a guide rod 20, and the surface of the guide rod 20 is sleeved with the movable plate 21.

[0043] The left view of the movable plate 21 is a reverse "L" structure, the inner wall of the movable plate 21 is fixedly connected with stress blocks 24, the stress blocks 24 are equidistantly distributed on the inner wall of the movable plate 21, the left and right sides of the stress blocks 24 are both inclined, the inner wall of the movable plate 21 is equidistantly fixedly connected with stand columns 22, the surface of the stand columns 22 is equidistantly fixedly connected with convex blocks 23, and the upper and lower sides of the convex blocks 23 are both inclined.

[0044] When slider 13 reciprocates in a straight line in the horizontal direction, slider 13 will drive auxiliary rod 19 to move synchronously. At this time, auxiliary rod 19 will intermittently push force block 24. When force block 24 is pushed, movable plate 21 rises (guide rod 20 makes movable plate 21 move only in the vertical direction). When auxiliary rod 19 continues to move until it no longer contacts force block 24, movable plate 21 falls. Then, force block 24 and movable plate 21 will reciprocate in a straight line in the vertical direction under the action of thrust, guide rod 20 and their own gravity. At this time, movable plate 21, column 22 and protrusion 23 also play the role of undulating water flow, accelerating the dissipation of heat inside the water flow and improving working efficiency. At the same time, force blocks 24 are evenly distributed on the lower surface of movable plate 21, increasing the working frequency of movable plate 21, thereby optimizing the effect of undulating water flow.

[0045] Example 3: Unlike Example 2, the reciprocating heat sink 30 allows for better heat dissipation from the water tank 1. Figures 8-10 As shown, the interior of the water tank 1 is connected to a heat sink 30 via a moving mechanism. The moving mechanism includes a pressure-bearing rod 25 fixedly connected to the inner wall of the water tank 1, and a pressure-bearing block 26 is sleeved on the surface of the pressure-bearing rod 25. Tooth blocks 31 are fixedly connected at equal intervals on the lower surface of the pressure-bearing block 26. A main gear 27 is fixedly connected to the end of the connecting shaft 7. A rotating shaft 28 is fixedly connected to the inner wall of the water tank 1. A secondary gear 29 is fixedly connected to the surface of the rotating shaft 28. Both the secondary gear 29 and the main gear 27 are half-gear structures. A heat sink 30 is fixedly connected to the upper surface of the pressure-bearing block 26. The end of the heat sink 30 is located on the outside of the tank cover 2. A guide groove 32 is provided on the surface of the tank cover 2.

[0046] When water tank 1 is working, heat sink 30 can quickly dissipate the heat inside water tank 1. During the rotation of connecting shaft 7, connecting shaft 7 will drive main gear 27 to rotate synchronously. When main gear 27 rotates, it will drive secondary gear 29 and rotating shaft 28 to rotate. At this time, pressure block 26 moves towards secondary gear 29 under the action of secondary gear 29 and tooth block 31. When main gear 27 and secondary gear 29 are not meshed, main gear 27 drives pressure block 26 towards main gear 27 through tooth block 31. Repeating the above process, pressure block 26 drives heat sink 30 to make reciprocating linear motion in the horizontal direction. Heat sink 30 can come into contact with more air, which can dissipate the heat inside water tank 1 more quickly, which is convenient for water tank 1 and water flow to cool down the train heater. During this process, pressure rod 25 makes pressure block 26 move only in the horizontal direction, ensuring stability.

[0047] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0048] Although the present application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be replaced by equivalent features, by those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
