[0031] Typical embodiments embodying the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various variations in different embodiments, all of which do not depart from the scope of the present disclosure, and the descriptions and drawings therein are for illustrative purposes in nature and not for limiting the present disclosure.

[0032] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of the present disclosure and in which are shown, by way of example, different exemplary structures, systems, and steps that can implement various aspects of the present disclosure. It should be understood that other specific solutions of components, structures, exemplary devices, systems, and steps can be used and structural and functional modifications can be made without departing from the scope of the present disclosure. Moreover, although terms such as "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein for convenience only, for example, according to the directions of the examples described in the drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present disclosure.

[0033] Refer to Figure 1 , which representatively shows a partial cross-sectional view of the sand-spreading device proposed by the present disclosure, in which the cross-sectional structure of the sand box 100 is specifically shown to expose the part of the sand quantity detection mechanism located inside the sand box 100. In this exemplary embodiment, the sand-spreading device proposed by the present disclosure is described by taking its application to an electric locomotive as an example. It is easy for those skilled in the art to understand that, in order to apply the relevant designs of the present disclosure to other types of rail locomotives, various modifications, additions, substitutions, deletions, or other changes are made to the following specific embodiments, and these changes are still within the scope of the principle of the sand-spreading device proposed by the present disclosure.

[0034] As Figure 1As shown, in an embodiment of the present disclosure, the sand spreading device proposed by the present disclosure includes a sand box 100 and a sand quantity detection mechanism. The sand box 100 is used to accommodate sand materials. A sand adding port 110 is provided at the top of the sand box 100, and a sand discharging port 120 is provided at the bottom of the sand box 100. The sand quantity detection mechanism includes a sensor and a processor. The sensor is disposed inside the sand box 100 and is used to generate an electrical signal in real time according to the sand quantity inside the sand box 100. The processor is connected to the sensor and an interaction module on the console of the driver's cab of the rail locomotive. The processor is used to receive the electrical signal sent by the sensor, calculate the sand quantity information of the sand box 100 according to the electrical signal, and interact with the user via the interaction module with the sand quantity information. Among them, the processor can be integrated into the overall vehicle control system of the rail locomotive or can be arranged separately. For example, it can be arranged inside the driver's cab or inside the electrical cabinet of the rail locomotive. Through the above design, the present disclosure uses the sensor to generate an electrical signal in real time according to the sand quantity, thereby realizing real-time monitoring of the remaining sand quantity inside the sand box 100. Thus, when the rail locomotive enters the depot, it is possible to select whether to add sand according to the monitored sand quantity, without the need to add sand again every time when entering the depot, reducing unnecessary work and improving work efficiency. At the same time, the present disclosure uses the processor to calculate the sand quantity information according to the electrical signal and perform interaction via the interaction module, thereby enabling the user to obtain the sand quantity information in real time, and the above information interaction can be completed inside the driver's cab without the need to read information near the sand spreading device, that is, without the need to frequently get off the vehicle to check, reducing the work intensity of the user and improving the user experience.

[0035] As Figure 1 shown, in an embodiment of the present disclosure, the sensor includes a first frame 210 and a plurality of sensing elements 220. Specifically, the first frame 210 extends from the top of the sand box 100 to the bottom of the sand box 100. The so-called "extends to the bottom of the sand box 100" can be understood as that a part of the first frame 210 is in contact with the bottom wall 130 of the sand box 100, or it can also be understood that there is a certain gap between the part of the first frame 210 extending to the bottom of the sand box 100 and the bottom wall 130 of the sand box 100. The plurality of sensing elements 220 are disposed on the first frame 210, and the plurality of sensing elements 220 are arranged at intervals and are respectively located at different height positions inside the sand box 100. On this basis, when the sensing element 220 is covered by sand materials, an electrical signal is generated. At this time, the electrical signal indicates that the sensing element 220 is in a covered state. In other words, for the sensing element 220 that does not generate an electrical signal, it is in an uncovered state. Accordingly, the processor determines the sand quantity inside the sand box 100 according to the number of sensing elements 220 that generate electrical signals. Through the above design, the acquisition and generation of the electrical signal in the present disclosure are relatively convenient and direct, and the judgment logic of the processor for the remaining sand quantity is relatively simple. Accordingly, the functional requirements for the processor can be reduced, which is beneficial to reducing the device cost.

[0036] As Figure 1As shown, based on the design that the sensor includes the first frame body 210, in an embodiment of the present disclosure, the sensor may be in a rod-shaped structure, for example, a rod-shaped structure extending in the vertical direction, and the sensor extends from the top of the sand box 100 to the bottom of the sand box 100 in the vertical direction. Through the above design, the present disclosure adopts the first frame body 210 to extend in the vertical direction, which can shorten the layout length of the first frame body 210 and reduce the occupation of the internal space of the sand box 100.

[0037] As Figure 1 shown, based on the design that the sensor includes a plurality of sensing elements 220 and the first frame body 210 extends in the vertical direction, in an embodiment of the present disclosure, the plurality of sensing elements 220 may be evenly arranged at intervals on the first frame body 210. Through the above design, the present disclosure can make the monitoring of the remaining sand amount inside the sand box 100 more uniform and sensitive at different height positions.

[0038] Based on the design that the sand spreading device includes the sensing element 220, in an embodiment of the present disclosure, the sensing element 220 may be a mechanical button. When the mechanical button is covered by sand material, the mechanical button is pressed to generate the above-mentioned electrical signal. In some other embodiments of the present disclosure, the sensing element 220 may adopt other types of components. For example, the sensing element 220 may also be a photosensitive element. When the photosensitive element is covered by sand material, the sensed light of the photosensitive element is blocked to generate the above-mentioned electrical signal.

[0039] Refer to Figure 2 , Figure 2 which representatively shows a partial cross-sectional view of the sand spreading device capable of embodying the principle of the present disclosure in another exemplary embodiment, in which the cross-sectional structure of the sand box 100 is specifically shown to expose the part of the sand amount detection mechanism located inside the sand box 100.

[0040] As Figure 2As shown, in an embodiment of the present disclosure, the sensor may include a pressure sensing sheet 310. The pressure sensing sheet 310 is disposed at the bottom of the sand box 100. The so-called "disposed at the bottom of the sand box 100" can be understood as the pressure sensing sheet 310 being in contact with the bottom wall 130 of the sand box 100, or it can also be understood that there is a certain gap between the pressure sensing sheet 310 and the bottom wall 130 of the sand box 100. On this basis, when the pressure sensing sheet 310 is covered by sand material, an electrical signal is generated. At this time, the electrical signal characterizes the pressure received by the pressure sensing sheet 310. In other words, when the pressure sensing sheet 310 does not generate an electrical signal (or when the pressure is 0), it means that the sand box 100 does not contain sand material, or it means that the sand material contained in the sand box 100 does not cover the pressure sensing sheet 310 to cause it to be pressed and generate an electrical signal. Accordingly, the processor calculates the amount of sand in the sand box 100 based on the pressure characterized by the electrical signal. Through the above design, the present disclosure uses the pressure information generated by the pressure sensing sheet 310 being pressed to calculate the remaining amount of sand, so that the sensor only needs to arrange one detection device (i.e., the pressure sensing sheet 310), which can reduce the number of components, and reduce the structural complexity and component cost of the sand amount detection mechanism.

[0041] As Figure 2 shown, based on the design that the sensor includes the pressure sensing sheet 310, in an embodiment of the present disclosure, the sensor may further include a second frame body 320. The second frame body 320 is disposed in the sand box 100, and the second frame body 320 extends from the top of the sand box 100 to the bottom of the sand box 100. The so-called "extends to the bottom of the sand box 100" can be understood as a part of the second frame body 320 being in contact with the bottom wall 130 of the sand box 100, or it can also be understood that there is a certain gap between the part of the second frame body 320 extending to the bottom of the sand box 100 and the bottom wall 130 of the sand box 100. On this basis, the pressure sensing sheet 310 is disposed on the second frame body 320, for example, it can be disposed at the lower end of the second frame body 320. In some other embodiments of the present disclosure, the second frame body 320 may also extend upward from the bottom of the sand box 100, and is not limited to this embodiment.

[0042] Based on the design that the sensor includes the pressure sensing sheet 310, in another embodiment not shown in the present disclosure, the pressure sensing sheet 310 may be disposed on the inner surface of the bottom wall 130 of the sand box 100. Through the above design, the present disclosure directly disposes the pressure sensing sheet 310 on the bottom wall 130 of the sand box 100 without the need to additionally provide other installation structures, thereby further reducing the number of parts and reducing the structural complexity.

[0043] As Figure 2As shown, based on the design that the sensor includes a pressure sensing sheet 310, in one embodiment of the present disclosure, the bottom wall 130 of the sand box 100 is provided with a sand discharge port 120. On this basis, the orthographic projection pattern of the pressure sensing sheet 310 on the bottom wall 130 can be staggered with the sand discharge port 120. The so-called "staggered arrangement" can be understood as the orthographic projection pattern of the pressure sensing sheet 310 and the sand discharge port 120 do not overlap at all. Further, the edge of the orthographic projection pattern of the pressure sensing sheet 310 and the edge of the sand discharge port 120 can be arranged at intervals, or it can be understood as the orthographic projection pattern of the pressure sensing sheet 310 and the sand discharge port 120 only partially overlap. Through the above design, the present disclosure can reduce the pressure sensing sheet 310 blocking the sand discharge port 120 and affecting the sand spreading function of the sand spreading device.

[0044] In one embodiment of the present disclosure, the processor can issue an alarm when the amount of remaining sand in the sand box 100 drops to a preset lower limit. Figure 1 Taking the sensor used in the illustrated embodiment as an example, the processor can determine that the amount of remaining sand has reached the lower limit and issue an alarm when only one sensing element 220 (i.e., the sensing element 220 with the lowest height) generates an electrical signal, or when no sensing element 220 generates an electrical signal. Figure 2 Taking the sensor used in the illustrated embodiment as an example, the processor can determine that the remaining sand amount has reached a lower limit and issue an alarm when the pressure value represented by the electrical signal generated by the pressure sensing sheet 310 is less than or equal to a lower pressure limit, or when the pressure sensing sheet 310 does not generate an electrical signal.

[0045] It should be noted here that the sand spreading devices shown in the drawings and described in this specification are only a few examples of the many types of sand spreading devices that can adopt the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are by no means limited to any details or any components of the sand spreading devices shown in the drawings or described in this specification.

[0046] Based on the above detailed description of several exemplary embodiments of the sand spreading device proposed in the present disclosure, an exemplary embodiment of a railway locomotive proposed in the present disclosure will be described below.

The sand quantity detection mechanism includes a sensor and a processor. The sensor is disposed inside the sand box 100 and is used to generate an electrical signal in real time according to the sand quantity inside the sand box 100.

Thus, when the rail locomotive enters the depot, it is possible to select whether to add sand according to the monitored sand quantity, without the need to re-add sand every time when entering the depot, reducing unnecessary work and improving work efficiency. At the same time, the present disclosure utilizes the processor to calculate the sand quantity information according to the electrical signal and perform interaction via the interaction module, thereby enabling the user to obtain the sand quantity information in real time, and the above information interaction can be completed inside the driver's cab without the need to read information near the sand-spreading device, reducing the work intensity of the user and improving the user experience.
