DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0028] Example 1:

[0029] See also Figure 1-2 and Figure 4An automatic snow-melting and ice-removing shutter comprises a shutter body and a heating unit. The shutter body is mounted on the air inlet and outlet of a locomotive by bolts. The shutter body comprises a frame 1, twenty-five air guide grilles 2 and twenty-four dust collection grilles 3. Figure 4 , all air guide grilles 2 are arranged in parallel along the length direction of the frame 1, and both ends of each air guide grille 2 are connected to the frame 1; all dust collecting grilles 3 are arranged in parallel along the length direction of the frame 1, and both ends of each dust collecting grille 3 are connected to the frame 1, and a dust collecting grille 3 is arranged between any two adjacent air guide grilles 2; the dust collecting grille 3 is a U-shaped structure and its opening is facing the air intake direction; the air guide grille 2 includes a windward surface and an air guide surface arranged in sequence along the air flow direction, the air guide surfaces are located on both sides of the windward surface and both are arc-shaped structures, and a gas flow channel is formed between the air guide surface and the outer wall of the dust collecting grille 3, which is convenient for guiding the wind to the dust collecting grille 3, so that the dust and rainwater entrained in the wind are guided to the dust collecting grille 3 and then flow out, which will not affect the normal operation of the blinds; The cavity formed by the connection of the wind-guiding surface and the windward surface is used to accommodate the heating element 5. Specifically, the main body of the heating element 5 is accommodated in the cavity, and the front end of the heating element 5 (i.e., the end of the heating element 5 connected to the power supply) is fixed to the wind-guiding grille 2 by an end clamp, and the end (i.e., the other end of the heating element 5 away from the front end) is fixed to the wind-guiding grille 2 by a gasket and a nut. The end clamps and nuts are used to fix the heating element 5 here, which is easy to disassemble and assemble, and convenient for subsequent maintenance. In addition, in order to ensure the dust collection effect, embodiment 1 can also choose to set two additional dust collecting grilles 3 on both sides of each dust collecting grille 3 (the number of the additional dust collecting grilles 3 is twenty-five), and the U-shaped structure opening direction of the additional dust collecting grille 3 is set directly opposite to the end of the wind-guiding surface of the wind-guiding grille 2 away from the windward surface.

[0030] The heating unit includes a power supply (not shown in the figure), a control component 4 and a heating component. The heating component is connected to the power supply through a circuit. The power supply is arranged on the frame 1. The control component 4 is arranged on the circuit and is located between the heating component and the power supply. The heating component includes a plurality of heating components 5 (specifically heating tubes with a voltage resistance level of up to AC3000V). The number of the heating components 5 is the same as the number of the air guide grille 2, and the two are arranged in a one-to-one correspondence. The heating components 5 are arranged in close contact with the inner wall of the cavity of the air guide grille 2, so that the heating components 5 can heat the air guide grille 2 efficiently and quickly.

[0031] The number of the heating components is three, and each group of heating components is arranged in parallel, which facilitates the coordinated control of the single heating work or parallel heating work of each group of heating components. However, similar foreign products all adopt a series structure. If a single heating component is damaged, the heating function will be lost. In addition, the heating components are difficult to disassemble and can only be returned to the factory for replacement, which is costly to maintain.

[0032] The heating elements 5 in the same group of heating assemblies are all arranged in parallel to ensure that the heating elements 5 work independently and avoid affecting the work of other heating elements 5 due to damage of a single heating element 5.

[0033] Along the setting order of the air guide grille 2, the first heating element 5 in each heating assembly is set in sequence, and then the second heating element 5 in each heating assembly is set in sequence, until the last heating element 5 in each heating assembly is set. This setting method belongs to the staggered setting method, that is, the heating elements 5 in any group of heating assemblies are evenly dispersed in the air guide grilles 2 set in sequence, and the heating elements 5 in one group of heating assemblies are separated by the heating elements 5 in the other two groups of heating assemblies. When the heating assemblies are set in parallel, the problem of uniform heating of the blinds due to abnormality of a certain group of heating assemblies will not occur, thereby ensuring the snow melting and ice removal effect of the blinds. For details, see Figure 3 In the circuit diagram of the three groups of heating components, according to the sequential arrangement order of the air guide grille 2, the three groups of heating components are respectively recorded as the first group of heating components A, the second group of heating components B and the third group of heating components C;

[0034] The arrangement order of the heating elements 5 corresponding to the air guide grilles 2 in the first group of heating components A is sequentially numbered 1#, 4#, 7#, 10#, 13#, 16#, 19#, 22#, and 25#, i.e., the 1# heating element 5 is arranged in the cavity of the first air guide grille 2, the 4# heating element 5 is arranged in the cavity of the fourth air guide grille 2, and so on. The 25# heating element 5 is arranged in the cavity of the twenty-fifth air guide grille 2; in addition, the 25# heating element 5 is grounded;

[0035] The arrangement order of the heating elements 5 corresponding to the air guide grilles 2 in the second group of heating assemblies B is numbered 2#, 5#, 8#, 11#, 14#, 17#, 20# and 23#, that is, the 2# heating element 5 is arranged in the cavity of the second air guide grille 2, the 5# heating element 5 is arranged in the cavity of the fifth air guide grille 2, and so on, and the 23# heating element 5 is arranged in the cavity of the twenty-third air guide grille 2;

[0036] The arrangement order of the heating elements 5 corresponding to the air guide grilles 2 in the third group of heating assemblies C is numbered 3#, 6#, 9#, 12#, 15#, 18#, 21# and 24#, that is, the 3# heating element 5 is arranged in the cavity of the third air guide grille 2, the 6# heating element 5 is arranged in the cavity of the sixth air guide grille 2, and so on, and the 24# heating element 5 is arranged in the cavity of the twenty-fourth air guide grille 2;

[0037] In addition, a second standby heating element P is provided in parallel in the second group of heating components B, and a third standby heating element M is provided in parallel in the third group of heating components C. The second standby heating element P and the third standby heating element M serve as standby heating elements 5 and are connected to the ground.

[0038] The control element 4 includes a primary temperature protection switch and a secondary temperature protection switch.

[0039] The primary temperature protection switch is a temperature-sensitive switch 4.1, and the secondary temperature protection switch is a fuse 4.2. When the ambient temperature falls below the set temperature of the temperature-sensitive switch 4.1, the temperature-sensitive switch 4.1 closes, activating the heating element. When the temperature of a particular temperature-sensitive switch 4.1 exceeds the set temperature, the corresponding circuit automatically disconnects, suspending operation of the corresponding heating element. If the temperature-sensitive switch 4.1 fails to disconnect, and the temperature rises above the set temperature of the fuse 4.2, the fuse 4.2 opens, causing the circuit to enter a protection state.

[0040] The frame 1 includes a first frame 1.1, a second frame 1.2, a first fixing plate 1.3, a second fixing plate 1.4, a first cover plate 1.5 and a second cover plate 1.6. The first frame 1.1 and the second frame 1.2 are arranged opposite to each other and are located at both ends of the arrangement direction of all air guide grilles 2; the first fixing plate 1.3 and the second fixing plate 1.4 are arranged along the arrangement direction of the air guide grilles 2 and are respectively used to fix the two ends of the air guide grilles 2 and the dust collection grille 3, and the two ends of the first fixing plate 1.3 and the second fixing plate 1.4 are respectively connected to the first frame 1.1 and the second frame 1.2; the first cover plate 1.5 is arranged on the first fixing plate 1.3, and the second cover plate 1.6 is arranged on the second fixing plate 1.4. The two ends of the first cover plate 1.5 and the second cover plate 1.6 are respectively connected to the first frame 1.1 and the second frame 1.2;

[0041] The first fixing plate 1.3, the first cover plate 1.5, the second fixing plate 1.4 and the second cover plate 1.6 are all provided with through holes for leading out wires connected to the heating element;

[0042] The automatic snow-melting and de-icing shutter is vertically mounted at the air inlet and outlet of a motorcycle. The first cover plate 1.5 and the first fixing plate 1.3 are located at the top of the automatic snow-melting and de-icing shutter, and the second cover plate 1.6 and the second fixing plate 1.4 are located at the bottom of the automatic snow-melting and de-icing shutter. The second fixing plate 1.4 and the second cover plate 1.6 are provided with outlets for discharging dust, wind, sand and rainwater from the dust collecting grid 3.

[0043] The two ends of the air guide grille 2 are respectively fixed to the first fixing plate 1.3 and the first cover plate 1.5 and to the second fixing plate 1.4 and the second cover plate 1.6 through a first fixing member (specifically a pipe clamp); the two ends of the dust collecting grille 3 are respectively fixed to the first fixing plate 1.3 and the first cover plate 1.5 and to the second fixing plate 1.4 and the second cover plate 1.6 through a first fixing member (specifically a pipe clamp).

[0044] The automatic snow-melting and de-icing shutter further comprises two sealing pads (not shown in the figure), one of which is arranged between the first cover plate 1.5 and the first fixed plate 1.3, and the other of which is arranged between the second cover plate 1.6 and the second fixed plate 1.4. The arrangement of the two sealing pads facilitates the sealing of the top and bottom of the automatic snow-melting and de-icing shutter, so as to prevent rainwater from entering the inside of the automatic snow-melting and de-icing shutter.

[0045] The automatic snow-melting and de-icing shutter further comprises a waterproof joint 1.7 arranged on the frame 1, which is used for circuit access and exit. The arrangement of the waterproof joint 1.7 prevents rainwater from entering the inside of the automatic snow-melting and de-icing shutter.

[0046] The arrangement of the sealing pad and the waterproof joint 1.7 in Embodiment 1 can ensure that the inside of the automatic snow-melting and de-icing shutter reaches the waterproof level IP55.

[0047] The automatic snow-melting and de-icing shutter further comprises temperature sensing components 1.8 and wind speed sensing components 1.9 arranged on the frame 1 in parallel, which are connected with the power supply. The temperature sensing components 1.8 and the wind speed sensing components 1.9 facilitate real-time monitoring of the temperature and wind speed changes of the external environment of the automatic snow-melting and de-icing shutter, so as to facilitate the owner to protect the automatic snow-melting and de-icing shutter in time if the environment is harsh.

[0048] The automatic snow-melting and de-icing shutter comprises the following steps when in use:

[0049] Step S1, the automatic snow-melting and de-icing shutter is vertically installed on the locomotive air inlet and outlet through bolts;

[0050] Step S2, the temperature-sensitive switch 4.1 is used to automatically control the snow-melting and de-icing work of the electric heating assembly; specifically, when the external temperature is lower than the set temperature of the temperature-sensitive switch 4.1, the temperature-sensitive switch 4.1 is attracted, and the electric heating assembly works; when the temperature of a certain temperature-sensitive switch 4.1 exceeds the set temperature, the corresponding circuit is automatically disconnected, and the corresponding heating assembly is suspended; Step S2 realizes low-temperature automatic heating and high-temperature automatic disconnection protection, thereby achieving the purpose of automatic snow-melting and de-icing;

[0051] Step S3, when the temperature-sensitive switch 4.1 has an abnormal problem that cannot be disconnected, if the temperature is higher than the set temperature of the fuse 4.2, the fuse 4.2 is disconnected, so that the circuit enters a protection state.
