Description

Technical Field

[0001] This utility model belongs to the field of new energy locomotive technology, and more specifically, it relates to a sound and light alarm device for new energy locomotives. Background Technology

[0002] New energy locomotives, as an upgraded replacement for aging diesel locomotives, have been widely used in the traction operations of self-owned lines in steel and other enterprises. The locomotive operating environment includes numerous railway crossings and construction areas, with frequent personnel activity near the tracks. Therefore, a new energy locomotive audible and visual alarm device is needed for warning purposes. Existing new energy locomotive audible and visual alarm devices mainly consist of a mounting frame, a fixing base, an alarm mechanism, and a warning light cover. The device adopts an integrated design; the warning light cover is fixed to the upper part of the fixing base with bolts, and the fixing base has a built-in alarm mechanism that can simultaneously emit audible and visual warning signals, forming the main body of the device. Subsequently, the main body of the device is fastened to the mounting frame at the front and rear ends of the new energy locomotive, near the left and right indicator lights, to complete assembly and use.

[0003] A patent application with application number 202420205586.4 discloses a locomotive warning light, including a housing. A quick-fixing assembly is installed inside the housing, and a warning light body is mounted on one side of the quick-fixing assembly. The warning light body has locking blocks on both sides, and an auxiliary power generation assembly is mounted on the outside of the housing. The quick-fixing assembly includes a fixing compartment, inside which a first spring is installed. One end of the first spring is connected to a moving block, and a pin is connected to one side of the moving block. A slider is mounted on one side of the pin. This invention, through the quick-fixing assembly, enables rapid installation and removal of the warning light body, facilitating operation and improving the efficiency of disassembly, assembly, and maintenance. The power generation assembly converts the wind power generated by the locomotive during operation into electrical energy to power the warning light body, improving environmental friendliness.

[0004] Based on the above, existing audible and visual alarm devices for new energy locomotives mostly use sealing gaskets between the mounting base and the warning light cover to ensure the long-term operation of the alarm mechanism inside the light cover, thus achieving internal sealing protection. However, these sealing gaskets are constantly exposed to the vibration and temperature / humidity changes of locomotive operation, making them prone to aging and deformation, leading to seal failure. Early failure is often difficult to detect, and once the seal fails, moisture can easily accumulate inside the warning light cover, directly affecting the lifespan of the alarm mechanism. Furthermore, the mounting base is usually fastened to the mounting frame with bolts, and the continuous vibration generated during locomotive traction operations can easily cause the bolts to loosen. This potential hazard is also difficult to detect in time, potentially leading to the risk of the device falling off and being lost. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a new energy locomotive audible and visual alarm device. This addresses the shortcomings of existing new energy locomotive audible and visual alarm devices, which typically employ a sealing gasket between the mounting base and the warning light cover to ensure long-term operation of the alarm mechanism. However, this sealing gasket is constantly exposed to the vibrations and temperature / humidity changes of locomotive operation, making it prone to aging and deformation, leading to seal failure. Early failure is often difficult to detect, and once the seal fails, moisture can accumulate inside the warning light cover, directly impacting the lifespan of the alarm mechanism. Furthermore, the mounting base is usually secured to the mounting frame with bolts; the continuous vibrations generated during locomotive traction operations can easily cause these bolts to loosen, a risk that is also difficult to detect in time and may lead to the device falling off and being lost.

[0006] The purpose and effect of this utility model's audible and visual alarm device for new energy locomotives are achieved through the following specific technical means: A new energy locomotive audible and visual alarm device includes a fixed base, a connecting platform, a warning light cover, transmission contacts, a buzzer, a wiring harness groove, a sealing assembly, and a loosening assembly. The connecting platform is bolted to the top of the fixed base; the warning light cover is fixedly connected to the top of the connecting platform; two sets of transmission contacts are provided, and the two sets of transmission contacts are vertically slidably connected inside the fixed base; two sets of buzzers are provided, and the two sets of buzzers are fixedly installed on the left and right sides of the fixed base; the wiring harness groove is opened in the middle of the fixed base; the sealing assembly is disposed inside the fixed base; and the loosening assembly is disposed inside the fixed base.

[0007] Furthermore, the sealing assembly includes a sealing plate and a sealing gasket. The sealing plate is fixedly installed on the upper part of the fixed base, and the interior of the sealing plate is filled with color-changing silicone. The sealing gasket is looped around the outside of the sealing plate and is located between the fixed base and the connecting platform.

[0008] Furthermore, the sealing assembly also includes: an upper cover plate and a through hole, wherein the upper cover plate is snapped onto the top of the sealing plate; and the through hole is formed inside the upper cover plate.

[0009] Furthermore, the loosening assembly includes: a transmission rod and a first spring. The transmission rod is provided in two sets, and the two sets of transmission rods are vertically slidably connected inside the fixed base. The two sets of transmission rods are fixedly installed on the top of the two sets of transmission contacts. The first spring is provided in two sets, with one end of the two sets of first springs fixedly connected inside the fixed base, and the other end of the two sets of first springs fixedly connected to the upper part of the top of the two sets of transmission rods.

[0010] Furthermore, the loosening assembly also includes: a transmission plate and a second spring. The transmission plate is provided in two sets, and the two sets of transmission plates are slidably connected to the outside of the two sets of transmission rods, and the two sets of transmission plates are vertically slidably connected to the inside of the fixed base. The second spring is provided in two sets, one end of the two sets of second springs is fixedly connected to the lower part of the top of the two sets of transmission rods, and the other end of the two sets of second springs is fixedly connected to the upper part of the two sets of transmission plates.

[0011] Furthermore, the loosening component also includes a trigger switch, wherein two sets of trigger switches are provided, the two sets of trigger switches are fixedly installed inside the fixed base, the two sets of trigger switches are respectively located below the two sets of transmission plates, and the trigger switches and the buzzer are connected together by a wiring harness to form a switching circuit.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this invention features a sealing assembly. A sealing gasket forms the first layer of protection, while the interlocking structure of the sealing plate and connecting plate achieves a secondary seal, providing double protection to enhance the internal sealing of the warning light cover. The color-changing silicone inside the sealing plate absorbs infiltrated moisture, preventing damage to the alarm mechanism. Furthermore, the transparent material of the sealing plate and connecting plate allows staff to visually observe the color change of the silicone, enabling timely detection of sealing failures.

[0013] Secondly, this invention features a loosening component. Through the cooperation of a spring and a transmission structure, the transmission contact is pushed out when the bolt loosens, keeping the device elastically taut against the mounting surface and slowing down the loosening process. Simultaneously, the transmission structure triggers a switching circuit, driving a buzzer to emit a warning sound, quickly informing workers of the potential bolt loosening and preventing the device from falling off or being lost. Furthermore, the double-spring design ensures continuous movement of the transmission rod, guaranteeing the stable effectiveness of the warning function.

[0014] This utility model has the advantages of sealed protection, timely prompting, and convenient maintenance. It can effectively extend the service life of the alarm mechanism, improve the installation stability and safety of the device, and is easy to operate and has low maintenance costs. It can also ensure timely detection and maintenance of faults in complex environments. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example 1: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a new energy locomotive sound and light alarm device, including a fixed base 1, a connecting platform 3, a warning light cover 2, a transmission contact 4, a buzzer 5, a wiring harness groove 6, and a sealing assembly. The connecting platform 3 is bolted to the top of the fixed base 1; the warning light cover 2 is fixedly connected to the top of the connecting platform 3; two sets of transmission contacts 4 are provided, and the two sets of transmission contacts 4 are vertically slidably connected inside the fixed base 1; two sets of buzzers 5 are provided, and the two sets of buzzers 5 are fixedly installed on the left and right sides of the fixed base 1; the wiring harness groove 6 is opened in the middle of the fixed base 1; and the sealing assembly is disposed inside the fixed base 1.

[0023] The sealing assembly includes a sealing plate 102 and a sealing gasket 101. The sealing plate 102 is fixedly installed on the upper part of the fixed base 1, and the interior of the sealing plate 102 is filled with color-changing silicone. The sealing gasket 101 is looped around the outside of the sealing plate 102 and is located between the fixed base 1 and the connecting platform 3.

[0024] The sealing assembly further includes an upper cover plate 103 and a through hole 104. The upper cover plate 103 is snapped onto the top of the sealing bracket 102. The through hole 104 is formed inside the upper cover plate 103.

[0025] The specific usage and function of this embodiment are as follows: Both the sealing card holder 102 and the upper cover plate 103 are made of transparent plastic, allowing staff to visually observe the color change of the color-changing silicone inside the sealing card holder 102 and promptly grasp the sealing status.

[0026] The connecting platform 3 is bolted to the upper part of the fixed base 1, and the sealing gasket 101 between them forms the first layer of sealing protection. An audible and visual alarm mechanism is installed on the upper part of the fixed base 1. Through a circuit board and control mechanism, it links the speaker and warning bulb, triggering the control circuit to achieve the audible and visual alarm function. The warning light cover 2 is made of red or yellow semi-transparent plastic, while the connecting platform 3 is made of transparent plastic. The wiring harness passes through the wiring harness groove 6 and is then sealed to further ensure the sealing performance inside the warning light cover 2. When the fixed base 1 and the connecting platform 3 are connected, the sealing clip 102 precisely engages with the inside of the connecting platform 3, creating a sealed space inside the warning light cover 2, achieving secondary sealing reinforcement.

[0027] If the sealing gasket 101 fails to seal, moisture will enter the interior of the connecting platform 3 and seep into the sealing plate 102 through the through hole 104 of the upper cover 103. On the one hand, the color-changing silicone inside the sealing plate 102 will absorb the moisture and change color, thus drying the interior of the warning light cover 2 and preventing moisture from damaging the audible and visual alarm mechanism. On the other hand, staff can directly observe the color change of the silicone through the transparent connecting platform 3 and the sealing plate 102, quickly detect the sealing failure, and handle it in a timely manner.

[0028] Example 2: Based on Example 1, such as Figures 1 to 5 As shown, it also includes a loosening component, which is disposed inside the fixed base 1.

[0029] The loosening assembly includes a transmission rod 401 and a first spring 402. Two sets of transmission rods 401 are provided, and the two sets of transmission rods 401 are vertically slidably connected inside the fixed base 1. The two sets of transmission rods 401 are fixedly installed on the top of the two sets of transmission contacts 4. Two sets of first springs 402 are provided, and one end of the two sets of first springs 402 is fixedly connected inside the fixed base 1. The other end of the two sets of first springs 402 is fixedly connected to the upper part of the top of the two sets of transmission rods 401.

[0030] The loosening assembly further includes: a transmission plate 404 and a second spring 403. Two sets of transmission plates 404 are provided, and the two sets of transmission plates 404 are slidably connected to the outside of the two sets of transmission rods 401 respectively. The two sets of transmission plates 404 are vertically slidably connected to the inside of the fixed base 1. Two sets of second springs 403 are provided, and one end of the two sets of second springs 403 is fixedly connected to the lower part of the top end of the two sets of transmission rods 401, and the other end of the two sets of second springs 403 is fixedly connected to the upper part of the two sets of transmission plates 404.

[0031] The loosening component also includes a trigger switch 501. Two sets of trigger switches 501 are provided. The two sets of trigger switches 501 are fixedly installed inside the fixed base 1. The two sets of trigger switches 501 are respectively located below the two sets of transmission plates 404. The trigger switches 501 and the buzzer 5 are connected together by a wire harness to form a switching circuit.

[0032] The specific usage and function of this embodiment are as follows: In the normal state where the fixed base 1 is fixed to the locomotive installation position by bolts, the connection position presses the transmission contact 4 into the fixed base 1, which drives the transmission rod 401 to move and compresses the first spring 402. At this time, the movement of the transmission rod 401 drives the second spring 403 to move, and the second spring 403 drives the transmission plate 404 to move, so that the transmission plate 404 is a certain distance away from the trigger switch 501, and the elastic force of the first spring 402 is greater than the elastic force of the second spring 403.

[0033] When the bolts loosen, a gap will form between the fixed base 1 and the installation position. At this time, the pressure of the transmission contact 4 is released. Under the elastic action of the first spring 402, the first spring 402 drives the transmission rod 401 and the transmission contact 4 to move, causing the transmission contact 4 to push out from inside the fixed base 1. This creates an elastic tension between the fixed base 1 and the installation position, slowing down the loosening of the bolts. Simultaneously, the movement of the transmission rod 401 will drive the second spring 403 and the transmission plate 404 to move downwards. The transmission plate 404 presses the trigger switch 501, triggering it. This activates the buzzer 5 through the switching circuit, providing an audible alert so that workers can promptly detect the bolt loosening problem. If the bolt loosening causes the gap to continue to widen, the first spring 402 will push the transmission rod 401 to continue pushing out. During this process, the transmission rod 401 will overcome the elastic force of the second spring 403, preventing the transmission plate 404 from being blocked by the trigger switch 501 and hindering the further movement of the transmission rod 401.

[0034] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0035] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this embodiment should be included within the protection scope of this embodiment. Therefore, the protection scope of this embodiment should be determined by the protection scope of the claims.
