Description

Technical Field

[0001] This utility model relates to the field of antifreeze spraying technology, and in particular to an antifreeze spraying device. Background Technology

[0002] The braking system of a train contains many moving parts and pipelines, including liquid media that may freeze at low temperatures. The braking system is crucial to train safety; if any components in the braking system malfunction due to freezing, the train will struggle to brake effectively, posing a significant safety hazard.

[0003] A search revealed a Chinese patent with authorization announcement number CN207342971U, which discloses an antifreeze spraying device. The device includes a storage tank, with connecting rods symmetrically arranged on the left and right sides of the front of the tank. These connecting rods are fixedly connected to a vertical pole. A sliding groove is provided inside the vertical pole, and both ends of a horizontal bar are positioned within this groove. Several spray pipes are located within the horizontal bar, with the lower ends of the spray pipes connected to a manifold. One end of a flexible hose is connected to the manifold, and the other end of the hose is connected to the outlet of a water pump. The water pump is located within the storage tank. An electric telescopic rod is installed within the sliding groove, with its lower end fixedly connected to the bottom of the groove and its upper end fixedly connected to the horizontal bar. While the aforementioned patents have addressed some of the problems in the prior art to a certain extent, they still have some shortcomings: during spraying, when there is dust on the surface of the device to be sprayed, the dust particles will block the direct contact between the antifreeze and the device surface. The antifreeze may not adhere evenly to the device surface, but instead forms a discontinuous coating around the dust particles, so that the antifreeze cannot effectively protect the device after spraying. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that dust on the surface of the device can affect the spraying effect, so that the antifreeze cannot effectively protect the device after spraying. Therefore, an antifreeze spraying device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An antifreeze spraying device includes a housing, an electric telescopic rod fixedly mounted on the surface of the housing, a support frame fixedly connected to the top end of the electric telescopic rod, and the support frame slidably connected to the housing. The device further includes: two threaded rods, each rotatably connected to the support frame, with sliders threadedly connected to the surfaces of the two threaded rods, and spray nozzles fixedly connected to the surfaces of the sliders; a motor fixedly mounted at one end of each threaded rod; and a connecting frame fixedly connected to the side wall of the slider, with a cleaning brush provided on one side of the connecting frame.

[0007] Preferably, a telescopic hose is fixedly installed between the slider and the outer wall of the housing.

[0008] Preferably, a guide rod is fixedly connected to one side of the connecting frame, the other end of the guide rod is slidably connected to the cleaning brush, and a return spring is fixedly connected between the outer wall of the connecting frame and the outer wall of the cleaning brush.

[0009] Preferably, the slider is internally connected to a rotating rod, and cams are fixedly connected to both ends of the rotating rod, with the two cams arranged at a 90-degree angle.

[0010] Preferably, the outer wall of the rotating rod is fitted with a ratchet assembly, the ratchet assembly is rotatably connected to the inside of the slider, the inner wall of the ratchet assembly is fixedly connected to a limit block, the outer wall of the rotating rod is rotatably connected to a rotating plate that cooperates with the limit block, and a torsion spring is provided between the rotating plate and the outer wall of the rotating rod.

[0011] Preferably, the ratchet assembly includes a pawl portion and a ratchet portion that cooperates with the pawl portion. Both the pawl portion and the ratchet portion are rotatably connected to the slider. A bevel gear is fixedly connected to the outer wall of the ratchet portion.

[0012] Preferably, a limit frame is fixedly connected to the outer wall of the slider, and a connecting rod is rotatably connected inside the limit frame. One end of the connecting rod is fixedly connected to a bevel gear two that meshes with a bevel gear one, and the other end of the connecting rod is fixedly connected to a spur gear. A rack that meshes with the spur gear is provided on one side of the spur gear, and the rack is fixedly connected to the support frame.

[0013] Preferably, a curved connecting spring is fixedly connected between the outer wall of the rotating rod and the slider.

[0014] Compared with the prior art, the present invention provides an antifreeze spraying device, which has the following beneficial effects:

[0015] 1. This antifreeze spraying equipment uses a motor to control the rotation of a threaded rod, causing a slider to slide within a support frame. Simultaneously, a built-in water pump draws antifreeze from inside the housing into a telescopic hose, which is then sprayed from the nozzle onto the surface of the device to be sprayed. As the slider slides, a cleaning brush can remove dust and other impurities from the surface of the device to be sprayed, preventing dust particles from obstructing direct contact between the antifreeze and the device surface and affecting the spraying effect.

[0016] 2. This antifreeze spraying equipment works by sliding the slider to the right, causing the spur gear to rotate under the action of the rack. This rotation, via a connecting rod, drives the second bevel gear to rotate. This allows the ratchet to rotate counter-clockwise through the meshing of the first and second bevel gears, while the pawl remains stationary. The rotating rod, under the action of the connecting spring, uses a cam to push out the right-side cleaning brush to clean dust and other impurities from the surface of the spraying device. When the slider slides to the left, the ratchet drives the pawl to rotate clockwise, causing the rotating rod to rotate under the cooperation of the limit block and the rotating plate. This causes the left-side cam to push out the left-side cleaning brush, while the right-side cleaning brush returns to its original position under the force of the return spring. This ensures that the area to be sprayed is always cleaned during spraying, preventing the cleaning brush on the other side from damaging the antifreeze coating. Attached Figure Description

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: Refer to Figures 1-7 An antifreeze spraying device includes a housing 1, an electric telescopic rod 2 fixedly mounted on the surface of the housing 1, a support frame 3 fixedly connected to the top of the electric telescopic rod 2, and the support frame 3 slidably connected to the housing 1. It also includes two threaded rods 4, each rotatably connected to the support frame 3, with sliders 6 threadedly connected to the surfaces of the two threaded rods 4, and a spray head 7 fixedly connected to the surface of the sliders 6. A motor 5 is fixedly mounted at one end of each threaded rod 4. A connecting frame 9 is fixedly connected to the side wall of the sliders 6, a cleaning brush 11 is provided on one side of the connecting frame 9, a telescopic hose 8 is fixedly installed between the sliders 6 and the outer wall of the housing 1, a guide rod 10 is fixedly connected to one side of the connecting frame 9, the other end of the guide rod 10 is slidably connected to the cleaning brush 11, and a return spring 12 is fixedly connected between the outer wall of the connecting frame 9 and the outer wall of the cleaning brush 11.

[0028] When the above technical solution is in use, the screw rod 4 is rotated by the motor 5, and the slider 6 slides in the support frame 3 under the guidance of the screw rod 4. This causes the connecting frame 9, which is fixedly connected to one side of the slider 6, to slide synchronously. This allows the cleaning brush 11 to clean the dust and other impurities on the surface of the spraying device under the push of the guide rod 10 fixedly connected to the surface of the connecting frame 9. At the same time, the built-in water pump draws the antifreeze inside the housing 1 into the telescopic hose 8 and then sprays it out from the nozzle 7 to spray the surface of the spraying device. This avoids the problem that dust particles will block the direct contact between the antifreeze and the surface of the device, thus affecting the spraying effect.

[0029] Example 2: Further, referring to Figures 1-7The slider 6 is internally connected to a rotating rod 13. Cams 14 are fixedly connected to both ends of the rotating rod 13, with the two cams 14 arranged at a 90-degree angle. A ratchet assembly 22 is fitted onto the outer wall of the rotating rod 13, and the ratchet assembly 22 is rotatably connected to the inside of the slider 6. A limit block 23 is fixedly connected to the inner wall of the ratchet assembly 22. A rotating plate 24, which cooperates with the limit block 23, is rotatably connected to the outer wall of the rotating rod 13. A torsion spring 25 is provided between the rotating plate 24 and the outer wall of the rotating rod 13. The ratchet assembly 22 includes a pawl portion 221 and a ratchet portion 222 that cooperates with the pawl portion 221. Both the ratchet part 222 and the slider 6 are rotatably connected. A bevel gear 16 is fixedly connected to the outer wall of the ratchet part 222. A limit frame 17 is fixedly connected to the outer wall of the slider 6. A connecting rod 18 is rotatably connected inside the limit frame 17. A bevel gear 19 that meshes with the bevel gear 16 is fixedly connected to one end of the connecting rod 18. A spur gear 20 is fixedly connected to the other end of the connecting rod 18. A rack 21 that meshes with the spur gear 20 is provided on one side of the spur gear 20. The rack 21 is fixedly connected to the support frame 3. A curved connecting spring 15 is fixedly connected between the outer wall of the rotating rod 13 and the slider 6.

[0030] In use, the above technical solution involves sliding the slider 6 to the right, causing the spur gear 20 to rotate under the action of the rack 21. This, in turn, drives the bevel gear 19 to rotate via the connecting rod 18. This allows the ratchet portion 222 to engage with the bevel gear 19 through the meshing of the first bevel gear 16. Figure 7 When the viewing angle is rotated counterclockwise, the pawl 221 will not rotate. Consequently, under the action of the connecting spring 15, the rotating rod 13 can push the right-hand cleaning brush 11 out via the cam 14 to clean dust and other impurities from the surface of the spraying device. When the slider 6 slides to the left, the ratchet 222 drives the pawl 221 to... Figure 7 The viewing angle is rotated clockwise, causing the rotating rod 13 to rotate in cooperation with the limiting block 23 and the rotating plate 24. This causes the left cam 14 to push out the left cleaning brush 11, while the right cleaning brush 11 is reset by the elastic force of the return spring 12. This ensures that the area to be sprayed is always cleaned during spraying, preventing the cleaning brush 11 on the other side from damaging the antifreeze coating.

[0031] It should be noted that when the slider 6 slides to the left, the left cam 14 pushes out the left cleaning brush 11, and the ratchet part 222 drives the pawl part 221 to continue rotating. The rotation of the rotating plate 24 can prevent the rotating rod 13 from jamming and causing the slider 6 to stop sliding. The torsion spring 25 can provide the force for the rotating plate 24 to reset. When the slider 6 slides to the right again, the elastic force of the connecting spring 15 drives the rotating rod 13 to rotate, so that the right cam 14 resets and pushes out the right cleaning brush 11 again.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
