Description

Technical Field

[0001] This utility model belongs to the field of radiator technology, and in particular relates to a radiator front protective net that is easy to replace. Background Technology

[0002] A radiator is any device used to transfer heat from one medium to another in order to control the temperature of the heat-generating element. It is mainly used for heat dissipation in electronic equipment and industrial and household applications. The radiator of a railcar is an important component of the railcar, mainly used to cool the engine and other critical systems of the railcar. In order to enhance the safety performance of the radiator, a front protective net is usually installed at the air inlet of the radiator to prevent stones, paper scraps and other debris from entering the radiator and causing damage. A simple and practical diamond-shaped front protective mesh for a radiator is disclosed in the existing patent announcement document CN217926063U, comprising: a diamond-shaped protective mesh; a frame unit disposed on the outer circumferential direction of the diamond-shaped protective mesh, the frame unit being capable of covering and fixing the diamond-shaped protective mesh; and a connecting unit comprising a first connecting part and a second connecting part, the first connecting part being disposed on the left and right sides of the radiator, and the second connecting part being disposed on the left and right sides of the frame unit, the first connecting part and the second connecting part being detachably connected; wherein, the second connecting part is flush with the rear sidewall of the frame unit; However, it still has the following drawbacks in practical use: The aforementioned diamond-shaped front protective net for radiators is covered and fixed by a frame unit, and the frame unit is installed on the radiator by a first connecting part and a second connecting part. However, in use, the first connecting part and the second connecting part are generally installed and connected to the frame unit and the radiator by bolts. When installing and disassembling the diamond-shaped protective net, special tools are required, which makes it inconvenient to quickly install and disassemble the diamond-shaped protective net. The aforementioned diamond-shaped front protective mesh for radiators protects the air inlet of the radiator. However, during prolonged use, dust and other debris accumulate on the surface of the mesh, affecting the air intake efficiency of the radiator. Therefore, the mesh needs to be cleaned regularly. To ensure safety during cleaning, the radiator is usually shut off, resulting in longer intervals between cleanings, which in turn affects the air intake efficiency. Conversely, shorter intervals between cleanings not only increase the workload of staff but also negatively impact the operation of the radiator.

[0003] To address these issues, we provide an easily replaceable front radiator guard. Utility Model Content

[0004] The purpose of this utility model is to provide a radiator front protective net that is easy to replace. The first and second fixing strips are connected and fixed by a connecting rod, and the radiator shell and the mounting frame are installed and fixed by the first and second fixing strips. This solves the problem of the existing front protective net being inconvenient to replace quickly. At the same time, the wire mesh is wound up and down by a motor-driven winding shaft, so that the part of the wire mesh without dust is located inside the mounting frame to protect the radiator shell, solving the problem of the existing short interval between regular dust cleaning.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a replaceable front protective net for a radiator, comprising a radiator housing. A mounting frame is provided at the air inlet of the radiator housing via a fixing assembly. The fixing assembly includes a first fixing strip fixedly connected to the mounting frame and a second fixing strip fixedly connected to the radiator housing. Connecting rods are rotatably connected to both ends of the first fixing strip. The front end of the connecting rod extends to the front of the first fixing strip and is fixedly connected to a rotating plate. A through groove is provided on one side of the end face of the second fixing strip. The rear end of the connecting rod passes through the through groove and is welded with a protrusion. A protective assembly is provided inside the mounting frame. The protective assembly includes mounting shells fixedly connected to the outer walls of both sides of the mounting frame and a wire mesh penetrating the mounting frame. A winding shaft is rotatably connected inside each mounting shell. A motor for driving the winding shaft is fixedly connected to the rear end of each mounting shell via a mounting bracket. Both ends of the wire mesh are wound around the outer wall of the winding shaft.

[0006] A further feature of this invention is that positioning holes are provided around the air inlet of the radiator housing, and positioning posts are fitted inside the positioning holes with clearance. The front ends of the positioning posts extend to the outside of the positioning holes and are fixedly connected to the rear end face of the mounting frame.

[0007] A further feature of this invention is that an L-shaped plate is welded to the front end face of the first fixing strip, and the longitudinal support arms of the L-shaped plate are fixedly connected to the top and bottom center positions of the mounting frame, respectively.

[0008] A further feature of this invention is that a limiting hole is provided on the other side of the end face of the second fixing strip, a limiting rod is fitted inside the limiting hole with a clearance, and the front end of the limiting rod is movably connected to the rotating plate.

[0009] A further feature of this invention is that a first limiting plate is fixedly connected to the outer wall of the limiting rod, the first limiting plate is located between the second fixing strip and the rotating plate, the front end of the limiting rod extends to the front of the rotating plate and is fixedly connected to the second limiting plate, and a return spring is sleeved on the outer side of the limiting rod, with the two ends of the return spring fixedly connected to the facing surfaces of the rotating plate and the first limiting plate, respectively.

[0010] A further feature of this invention is that a circular groove is provided on the other side of the front end face of the rotating plate, and a ring magnet is fixedly connected inside the circular groove.

[0011] A further feature of this invention is that multiple L-shaped frames are fixedly connected at equal intervals on both sides of the front end face of the mounting frame, and the longitudinal support arms of the L-shaped frames are fixedly connected at equal intervals to the outer wall of the mounting shell on the side away from the mounting frame.

[0012] A further feature of this invention is that a driven gear is fixedly connected to the top end of the winding shaft, the driven gear is located above the outside of the mounting housing, and a driving gear is fixedly connected to the output shaft of the motor, the driving gear meshing behind the driven gear.

[0013] A further feature of this invention is that an electromagnetic brake is fixedly connected to the bottom of the mounting housing, and the brake rotor of the electromagnetic brake is fixedly connected to the bottom end of the winding shaft.

[0014] This utility model has the following beneficial effects: This invention utilizes a fixed assembly. By rotating a rotating plate, the connecting rod rotates synchronously, aligning the protrusion on the connecting rod with the notch in the through groove. The mounting frame then moves backward until the positioning post is fully fitted into the positioning hole. At this point, the rear end of the connecting rod completely penetrates the through groove. When the protrusion is completely behind the second fixing strip, the rotating plate is rotated again, separating the protrusion from the notch in the through groove. The installation and disassembly of the mounting frame and protective net can be achieved through the rotation of the rotating plate and the connecting rod, facilitating quick disassembly and replacement of the protective net.

[0015] This invention, by setting up a protective component, shuts off the electromagnetic brake and starts the motor. After the electromagnetic brake is de-energized, the restriction on the winding shaft is released. At the same time, the motor's output shaft drives the winding shaft to rotate through the drive gear and driven gear. At this time, one side of the winding shaft winds up one end of the wire mesh, while the other side winds up and unwinds the other end. This allows the dust-free parts of the wire mesh to move into the mounting frame. By changing different parts of the wire mesh, the number of times the wire mesh needs to be cleaned is reduced, the cleaning interval is extended, the workload of the staff is reduced, and the cleaning of the wire mesh is also avoided from affecting the operation of the radiator, thus facilitating the protection of the radiator.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this is the first embodiment of the present invention. This embodiment provides a replaceable front protective net for a radiator, including a radiator housing 1. An installation frame 3 is provided at the air inlet of the radiator housing 1 via a fixing component 2. The fixing component 2 includes a first fixing strip 201, a second fixing strip 202, a connecting rod 203, and a rotating plate 204. The first fixing strip 201 and the second fixing strip 202 are connected and fixed by the connecting rod 203, and the radiator housing 1 and the installation frame 3 are installed and fixed by the first fixing strip 201 and the second fixing strip 202, which solves the problem of the existing front protective net being inconvenient to replace quickly.

[0028] Specifically, two first fixing strips 201 are provided and fixedly connected to the top and bottom of the mounting frame 3 respectively. Connecting rods 203 are rotatably connected to both sides of the end face of the first fixing strip 201. The first fixing strip 201 is used to install the connecting rods 203, thus enabling the connecting rods 203 to be rotatably mounted on the mounting frame 3. The front end of the connecting rod 203 extends to the front of the first fixing strip 201 and is fixedly connected to a rotating plate 204. The rotating plate 204 is located in front of the first fixing strip 201, facilitating the rotation of the connecting rods 203. Four second fixing strips 202 are provided and fixedly connected to both sides of the top and bottom of the radiator housing 1 respectively. A through groove 202a is opened on one side of the end face of the second fixing strip 202. The second fixing strips 202, in conjunction with the first fixing strips 201, achieve the connection between the radiator housing 1 and the mounting frame 3. The mounting frames 3 are connected. The inside of the through groove 202a has notches at the top and bottom that mate with the protrusion 203a. The through groove 202a is designed to allow the rear end of the connecting rod 203 to pass through the second fixing strip 202. The rear end of the connecting rod 203 passes through the through groove 202a and is welded with the protrusion 203a. The connecting rod 203 is designed to connect the first fixing strip 201 and the second fixing strip 202, thereby achieving the connection and fixation between the radiator housing 1 and the mounting frame 3. The protrusion 203a is designed to prevent relative movement between the connecting rod 203 and the second fixing strip 202. When the protrusion 203a is aligned with the notch of the through groove 202a, the connecting rod 203 can pass smoothly through the through groove 202a. When the protrusion 203a is not aligned with the notch of the through groove 202a, it can prevent relative movement between the connecting rod 203 and the through groove 202a.

[0029] Furthermore, positioning holes 101 are provided around the air inlet of the radiator housing 1. Positioning pins 301 are fitted inside the positioning holes 101 with clearance. The front ends of the positioning pins 301 extend to the outside of the positioning holes 101 and are fixedly connected to the rear end face of the mounting frame 3. The positioning holes 101 and positioning pins 301 are used to position the radiator housing 1 and the mounting frame 3, thereby facilitating the installation of the mounting frame 3 on the radiator housing 1. L-shaped plates 201a are welded to the front end face of the first fixing strip 201. The longitudinal support arms of the L-shaped plates 201a are fixedly connected to the top and bottom center positions of the mounting frame 3 respectively. The L-shaped plates 201a are used to install the first fixing strip 201 on the mounting frame 3 by bolts or welding. A limiting hole 202b is provided on the other side of the end face of the second fixing strip 202. A limiting rod 205 is fitted inside the limiting hole 202b with clearance. The front end of the limiting rod 205 is movably connected to the rotating plate 204. The limiting hole 202b and the limiting rod 205 are provided to limit the rotation of the rotating plate 204, thereby preventing the rotating plate 204 from spontaneously driving the connecting rod 203 to rotate, and thus preventing the radiator housing 1 from separating from the mounting frame 3 due to vibration of the radiator housing 1. A first limiting plate 205a is fixedly connected to the outer wall of the limiting rod 205. The first limiting plate 205a is located between the second fixing bar 202 and the rotating plate 204. The front end of the limiting rod 205 extends to the front of the rotating plate 204 and is fixedly connected to the second limiting plate 205b. A return spring 205c is sleeved on the outer side of the limiting rod 205. The two ends of the return spring 205c are fixedly connected to the facing surfaces of the rotating plate 204 and the first limiting plate 205a, respectively. The first limiting plate 205a and the second limiting plate 205b are used to limit the movement distance of the limiting rod 205 and prevent the connecting rod 203 from detaching from the first fixing bar 201. The return spring 205c is used to drive the connecting rod 203 to move spontaneously to the initial position, so that the rear end of the connecting rod 203 can move spontaneously into the limiting hole 202b when there is no external force. A circular groove 204a is provided on the other side of the front end face of the rotating plate 204. A ring magnet 204b is fixedly connected inside the circular groove 204a. The circular groove 204a is provided to install the ring magnet 204b. The ring magnet 204b is used to magnetically connect the first limiting plate 205a. The first limiting plate 205a is made of a material that can be attracted by a magnet, such as iron sheet.

[0030] The operation process of this embodiment is as follows: During installation, the mounting frame 3 and the radiator housing 1 are first aligned by aligning the positioning post 301 and the positioning hole 101. Then, the rotating plate 204 is rotated, which drives the connecting rod 203 to rotate synchronously, so that the protrusion 203a on the connecting rod 203 is aligned with the notch of the through groove 202a. Then, the mounting frame 3 is moved backward until the positioning post 301 is completely clearance-fitted into the positioning hole 101. At this time, the rear end of the connecting rod 203 completely penetrates the through groove 202a. When the protrusion 203a is completely located in the second fixed position... When the fixed bar 202 is behind, rotate the rotating plate 204 again, so that the protrusion 203a separates from the notch of the through groove 202a. Finally, apply external force to the second limiting plate 205b, so that the rear end of the limiting rod 205 moves towards the first fixed bar 201. When the limiting rod 205 is aligned with the limiting hole 202b, release the second limiting plate 205b. At this time, under the dual action of the annular magnet 204b and the return spring 205c, the rear end of the limiting rod 205 is fitted with a clearance inside the limiting hole 202b, thus fixing the mounting frame 3 to the radiator housing 1. Example 2

[0031] Please see Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a protective component 4 is provided inside the mounting frame 3. The protective component 4 includes a mounting shell 401, a wire mesh 402, a winding shaft 403, and a motor 404. The motor 404 drives the winding shaft 403 to wind and unwind the wire mesh 402, so that the part of the wire mesh 402 without dust is located inside the mounting frame 3 to protect the radiator shell 1, thus solving the problem of the existing short interval between periodic dust cleaning.

[0032] Specifically, two mounting shells 401 are provided and fixedly connected to the outer walls of the two sides of the mounting frame 3 respectively. A winding shaft 403 is rotatably connected inside each mounting shell 401. The mounting shell 401 is designed to install the winding shaft 403 and provide a closed space for it, thus preventing dust from adhering to the wire mesh 402 on the winding shaft 403. The winding shaft 403 is used to wind and unwind the wire mesh 402, and with the cooperation of the two winding shafts 403, the wire mesh 402 moves relative to the mounting frame 3. A motor 404 is fixedly connected to the rear end of each mounting shell 401 via a mounting bracket 404a. The motor 404 is used to drive the winding shaft 403 to rotate, and the switches of the two motors 404 are controlled by the same controller. When both motors 404 rotate forward simultaneously... The left motor 404 drives the winding shaft 403 to wind up the wire mesh 402, while the right motor 404 drives the winding shaft 403 to unwind the wire mesh 402, causing the wire mesh 402 to move to the left. When both motors 404 reverse simultaneously, the left motor 404 drives the winding shaft 403 to unwind the wire mesh 402, while the right motor 404 drives the winding shaft 403 to wind up the wire mesh 402, causing the wire mesh 402 to move to the right. The wire mesh 402 passes through the mounting frame 3, and both ends of the wire mesh 402 are wound around the outer wall of the winding shaft 403. The wire mesh 402 is used to seal the opening of the mounting frame 3, thereby protecting the air inlet of the radiator housing 1 and preventing stones, paper scraps, and other debris from entering the interior of the radiator housing 1.

[0033] Furthermore, multiple L-shaped frames 401a are fixedly connected at equal intervals on both sides of the front end face of the mounting frame 3. The longitudinal support arms of the L-shaped frames 401a are fixedly connected at equal intervals to the outer wall of the mounting shell 401 on the side away from the mounting frame 3. The transverse support arms and longitudinal support arms of the L-shaped frames 401a are fixedly connected to the mounting frame 3 and the mounting shell 401 respectively by bolts. Thus, the mounting shell 401 is fixed to the mounting frame 3 by setting up the L-shaped frames 401a. A driven gear 403a is fixedly connected to the top end of the take-up shaft 403. The driven gear 403a is located on the outside and above the mounting housing 401. A driving gear 404b is fixedly connected to the output shaft of the motor 404. The driving gear 404b meshes behind the driven gear 403a. The meshing connection between the driven gear 403a and the driving gear 404b realizes the transmission connection between the take-up shaft 403 and the output shaft of the motor 404, thereby enabling the output shaft of the motor 404 to drive the take-up shaft 403 to rotate. An electromagnetic brake 403b is fixedly connected to the bottom of the mounting housing 401. The brake rotor of the electromagnetic brake 403b is fixedly connected to the bottom end of the take-up shaft 403. The electromagnetic brake 403b is used to limit the rotation of the take-up shaft 403.

[0034] The rest of the structure is the same as in Example 1.

[0035] The operation process of this embodiment is as follows: the electromagnetic brake 403b is turned off and the motor 404 is started. After the electromagnetic brake 403b is de-energized, the restriction on the take-up shaft 403 is released. At the same time, the output shaft of the motor 404 drives the take-up shaft 403 to rotate through the driving gear 404b and the driven gear 403a. At this time, one side of the take-up shaft 403 winds up one end of the wire mesh 402, and the other side of the take-up shaft 403 winds up and unwinds the other end of the wire mesh 402. This allows the part of the wire mesh 402 that is not covered with dust to move into the interior of the mounting frame 3. By replacing different parts of the wire mesh 402, the number of times the wire mesh 402 needs to be cleaned is reduced, and the cleaning interval of the wire mesh 402 is extended.
