Description

Technical Field

[0001] This invention relates to the field of safety early warning technology, specifically to a dustproof safety early warning device. Background Technology

[0002] An audible and visual alarm is a device used in hazardous locations to issue warning signals to people through sound and light. It is widely used in emergencies such as fire alarms, gas leaks, and equipment malfunctions, and its applications are broad.

[0003] A triaxial apparatus is an instrument used for geotechnical testing. It can simulate the triaxial stress state of foundation soil and independently change the magnitude of the three principal stresses on the sample to determine the soil's strength and deformation characteristics. During testing, the triaxial apparatus needs to monitor multiple aspects and control units to complete the detection of pressure at multiple locations, temperature at multiple locations, and detection and judgment of liquid leaks. During the test, the triaxial apparatus controller receives feedback information from the sensors in real time and promptly determines the safety level. When an anomaly occurs, it will automatically handle it and interact with the experimental software to provide the location of the anomaly and the handling method or suggestion. Simultaneously, when an anomaly occurs, the triaxial apparatus controller will also activate an audible and visual alarm to provide effective warning to the test personnel.

[0004] However, traditional audible and visual alarms have the following drawbacks during use: 1. Because the audible and visual alarm is exposed to the outside even when not in use, dust in the air is more likely to accumulate around the speaker, causing the sound to become muffled and difficult to produce a clear alarm sound. Dust also accumulates on the lampshade surface, obscuring the light and making it difficult to emit a bright flashing light, thus affecting the alarm's warning effect; 2. When the audible and visual alarm needs to be removed from the controller, it is fixed to the controller with multiple screws, requiring tools to disassemble, thus reducing the ease of disassembly. Summary of the Invention

[0005] This invention aims to solve the technical problems of traditional audible and visual alarms, such as dust accumulation affecting the warning effect and inconvenience in disassembly. The purpose is to provide a dustproof safety warning device that can keep the audible and visual alarm from dust under normal circumstances by closing the dust cover, and automatically open the dust cover and trigger the audible and visual alarm to start the warning under abnormal circumstances. The audible and visual alarm is also easy to disassemble.

[0006] This invention is achieved through the following technical solution:

[0007] A dustproof safety warning device includes an audible and visual alarm, and further includes:

[0008] A dust cover can house the audible and visual alarm.

[0009] A drive mechanism is used to drive the dust cover to rotate in order to release or restore protection to the audible and visual alarm (2);

[0010] The switching mechanism includes an on button and an off button, wherein the off button and the on button are linked to the dust cover;

[0011] When the drive mechanism receives an abnormal signal, it drives the dust cover to open and triggers the start button to activate the audible and visual alarm; when the abnormal signal is disconnected, the drive mechanism drives the dust cover to close and triggers the stop button to turn off the audible and visual alarm.

[0012] Furthermore, the driving mechanism includes a driving element and a transmission assembly. The input end of the transmission assembly is connected to the output end of the driving element, and the output end of the transmission assembly is connected to the dust cover for driving the dust cover to rotate.

[0013] Furthermore, the driving element and the transmission assembly are connected by a lifting block, and the lifting block is connected to a pressing plate. The pressing plate presses the open and close buttons as the lifting block moves.

[0014] Furthermore, the transmission assembly includes a transmission gear and a drive rack. The transmission gear is fixed on the rotating shaft of the dust cover, and the drive rack is fixed on the lifting block. The drive rack meshes with the transmission gear.

[0015] Furthermore, a guide cylinder is fixed to the driving element, and a vertical guide rod passes through the guide cylinder. The top of the vertical guide rod is fixedly connected to the lifting block. By connecting the bottom of the lifting block to the vertical guide rod and the guide cylinder, the vertical movement of the lifting block is guided and limited, improving the stability of the vertical movement and ultimately ensuring the stability of the dust cover opening and closing.

[0016] Furthermore, the switching mechanism includes a bracket with an opening on one side, and the off button and the on button are respectively fixed on the upper and lower sides of the bracket opening.

[0017] Furthermore, it also includes a controller body, the top of which is provided with a support frame, and the audible and visual alarm is detachably connected to the support frame.

[0018] Furthermore, the support frame is provided with a bayonet, and the bottom of the audible and visual alarm is provided with an elastic buckle. The audible and visual alarm is installed on the support frame by engaging with the bayonet through the elastic buckle.

[0019] Furthermore, the audible and visual alarm is provided with a mounting base at the bottom, and a groove is provided on one end face of the mounting base, and the elastic buckle is installed in the groove.

[0020] Furthermore, the upper end face of the support frame is provided with a slide bar, one end of the slide bar is provided with a limiting plate, the slot is opened on the limiting plate, and the lower end face of the mounting base is provided with a sliding groove that is slidably connected to the slide bar.

[0021] Furthermore, the controller body has louvered heat dissipation holes on its side.

[0022] Furthermore, it also includes a dust sweeping assembly, which includes a transmission pulley assembly, a linkage shaft, a rotating plate, a connecting rod, a dust sweeping brush, and a transverse guide rod. The linkage shaft is linked with the dust cover through the transmission pulley assembly. The rotating plate is fixedly connected to the end of the linkage shaft. A dust sweeping brush is provided on the outside of the louvered heat dissipation holes. The two ends of the dust sweeping brush are slidably connected to the transverse guide rod. The transverse guide rod is fixedly connected to the side of the controller body. The two ends of the connecting rod are rotatably connected to the dust sweeping brush and the rotating plate, respectively.

[0023] Furthermore, the transmission pulley assembly includes a first synchronous pulley and a second synchronous pulley. The first synchronous pulley is fixed on the rotating shaft of the dust cover, and the second synchronous pulley is fixed on the linkage shaft. The first and second synchronous pulleys are connected by a synchronous belt drive. This invention, through the cooperation of the first synchronous pulley and the dust-sweeping assembly, enables the two dust-sweeping brushes to reciprocate during the rotation of the rotating shaft, thereby removing dust adhering to the louvered heat dissipation holes on the left and right sides of the triaxial controller. This avoids affecting the ventilation effect of the louvered heat dissipation holes and helps to improve the service life of the electronic components inside the controller body.

[0024] Furthermore, the transmission ratio between the first synchronous pulley and the second synchronous pulley is 1:2.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0026] 1. This invention uses a drive mechanism to rotate and open / close the dust cover. Simultaneously, the drive mechanism triggers different buttons on the switch mechanism. This allows the dust cover to automatically open in case of an abnormal situation, automatically triggering the audible and visual alarm to sound an alarm and flashing lights, providing an effective warning. Once the abnormality is resolved, the dust cover can be rotated to automatically close, automatically turning off the audible and visual alarm. This effectively prevents dust accumulation in the air from affecting the alarm sound and flashing lights, ensuring the alarm's warning effect.

[0027] 2. This invention connects the bottom of the lifting block to a vertical guide rod and a guide slide, thereby guiding and limiting the up-and-down movement of the lifting block, improving the stability of the up-and-down movement, and ultimately ensuring the stability of the dust cover opening and closing.

[0028] 3. This invention utilizes the cooperation of two elastic buckles and a strip-shaped latch. When it is necessary to remove the audible and visual alarm from the controller body, simply manually squeeze the two elastic buckles simultaneously in opposite directions to separate them from the strip-shaped latch. Then, slide the audible and visual alarm and the mounting base to the right to remove them. Moreover, since the disassembly process can be completed without the aid of tools, the ease of disassembling the audible and visual alarm is improved.

[0029] 4. By cooperating with the first synchronous pulley and the dust-sweeping assembly, the present invention can move two dust-sweeping brushes back and forth during the rotation of the rotating shaft, thereby sweeping away the dust attached to the louvered heat dissipation holes on the left and right sides of the controller, avoiding affecting the ventilation effect of the louvered heat dissipation holes, and helping to improve the service life of the electronic components inside the controller body.

[0046] Example 1

[0047] This embodiment 1 provides a dustproof safety early warning device, such as Figure 1-8 As shown, it includes:

[0048] Audible and visual alarm 2;

[0049] The dust cover 3 can house the audible and visual alarm 2.

[0050] The drive mechanism 4 is used to drive the dust cover 3 to rotate, so as to release or restore the protection of the audible and visual alarm 2;

[0051] The switching mechanism 6 includes an on button 602 and an off button 603, which are linked to the dust cover 3.

[0052] When the drive mechanism 4 receives an abnormal signal, the drive mechanism 4 drives the dust cover 3 to open and triggers the start button 602 to activate the audible and visual alarm 2. When the abnormal signal is disconnected, the drive mechanism 4 drives the dust cover 3 to close and triggers the stop button 603 to turn off the audible and visual alarm 2.

[0053] When the safety warning device of the present invention is in use, when the drive mechanism 4 receives an abnormal signal, the drive mechanism 4 moves to drive the dust cover 3 to rotate counterclockwise. When the dust cover 3 rotates 180° counterclockwise, it automatically opens the dust cover 3, thereby removing the obstruction of the audible and visual alarm 2 and disabling its protection. At the same time, when the dust cover 3 rotates 180° counterclockwise, it triggers the activation button 602, thereby activating the audible and visual alarm 2, which emits an alarm sound and flashing lights, providing an effective warning effect.

[0054] When the abnormal signal is disconnected, the drive mechanism 4 moves in the opposite direction, causing the dust cover 3 to rotate clockwise. When the dust cover 3 rotates 180° clockwise, it automatically closes. The closed dust cover 3 protects the audible and visual alarm 2, effectively preventing dust from accumulating around the horn of the audible and visual alarm 2, thus allowing the audible and visual alarm 2 to emit a clear alarm sound. It also prevents dust from accumulating on the surface of the lampshade of the audible and visual alarm 2, thus allowing the audible and visual alarm 2 to emit a bright flashing light. At the same time, when the dust cover 3 rotates 180° clockwise, it triggers the shut-off button 603, thereby turning off the audible and visual alarm 2, ensuring that the audible and visual alarm 2 is in the off state under normal use and that it automatically shuts off.

[0055] In summary, this invention drives the dust cover 3 to rotate and open / close via the drive mechanism 4. Simultaneously, it triggers different buttons on the switch mechanism 6. This enables the dust cover 3 to rotate and automatically open in case of an abnormal situation, automatically triggering the audible and visual alarm 2 to emit an alarm sound and flashing light, providing an effective warning effect. Once the abnormality is resolved, the dust cover 3 can rotate and automatically close, automatically triggering the audible and visual alarm 2 to shut down. This effectively prevents the accumulation of dust in the air from affecting the alarm sound and flashing light of the audible and visual alarm 2, ensuring its warning effect.

[0056] Example 2

[0057] This embodiment further illustrates the technical solution of the present invention based on Embodiment 1.

[0058] like Figure 1 , 2 As shown in Figures 5 and 8, the driving mechanism 4 includes a driving element 401 and a transmission assembly. The input end of the transmission assembly is connected to the output end of the driving element 401, and the output end of the transmission assembly is connected to the dust cover 3 for driving the dust cover 3 to rotate.

[0059] The drive element 401 and the transmission assembly are connected by a lifting block 402. The lifting block 402 is connected to the output end of the drive element 401. The lifting block 402 is also connected to a pressing plate 604. The pressing plate 604 presses the open button 602 and the close button 603 as the lifting block 402 moves.

[0060] The drive element 401 can be any existing element capable of performing linear motion, such as a hydraulic cylinder, pneumatic cylinder, or electric cylinder. The lifting block 402 is connected to the output end of the drive element 401 for easy connection with the transmission assembly, and linear motion is output through the drive element 401 and the lifting block 402.

[0061] In one or more specific embodiments, the pressing plate 604 is located on the side of the lifting block 402. The pressing plate 604 moves up and down with the lifting block 402 to press the open button 602 and the close button 603, thereby triggering the audible and visual alarm 2 to open / close. This achieves automatic opening / closing of the audible and visual alarm 2 while the dust cover 3 is opening / closing. Specifically:

[0062] When the drive mechanism 4 receives an abnormal signal, the drive element 401 drives the lifting block 402 to descend. The linear motion of the descent is converted into rotational motion through the transmission component, thereby causing the dust cover 3 to rotate counterclockwise. When the dust cover 3 rotates 180° counterclockwise, it automatically opens, thus removing the obstruction from the audible and visual alarm 2 and disabling its protection. At the same time, when the dust cover 3 rotates 180° counterclockwise, the pressing plate 604 connected to the lifting block 402 descends to the bottom and presses the trigger button 602, thereby activating the audible and visual alarm 2. The audible and visual alarm 2 emits an alarm sound and flashes lights, providing an effective warning effect.

[0063] When the abnormal signal is disconnected, the drive mechanism 4 moves in the reverse direction, causing the lifting block 402 to rise, which in turn causes the dust cover 3 to rotate clockwise. When the dust cover 3 rotates 180° clockwise, it automatically closes. The dust cover 3 in the closed state protects the audible and visual alarm 2, effectively preventing dust from accumulating around the speaker of the audible and visual alarm 2, thus enabling the audible and visual alarm 2 to emit a clear alarm sound. It also prevents dust from accumulating on the surface of the lampshade of the audible and visual alarm 2, thus enabling the audible and visual alarm 2 to emit a bright flashing light. At the same time, when the dust cover 3 rotates 180° clockwise, the pressing plate 604 connected to the lifting block 402 rises to the top, pressing the trigger stop button 603, thereby turning off the audible and visual alarm 2, so that the audible and visual alarm 2 is in the off state under normal use.

[0064] Example 3

[0065] This embodiment further illustrates the technical solution of the present invention based on Embodiment 2.

[0066] like Figure 1 , 2 As shown in Figures 5 and 8, the transmission assembly includes a transmission gear 302 and a drive rack 403. The transmission gear 302 is fixed on the rotating shaft 301 of the dust cover 3, and the drive rack 403 is fixed on the top of the lifting block 402. The drive rack 403 is meshed with the transmission gear 302.

[0067] The function of the transmission assembly is to convert the linear motion of the drive element 401 into rotational motion, thereby driving the rotating shaft 301 and the dust cover 3 connected to it to rotate. Specifically:

[0068] When the dust cover 3 needs to be opened, the output end of the drive element 401 moves the lifting block 402 downward in a straight line. The lifting block 402 drives the drive rack 403 to move downward as well. Then, the downward-moving drive rack 403 drives the transmission gear 302 to rotate counterclockwise, thereby driving the rotating shaft 301 and the dust cover 3 connected to it to rotate counterclockwise. When it reaches the limit position, the rotating shaft 301 and the dust cover 3 connected to it rotate 180 degrees counterclockwise, thus automatically opening the dust cover 3.

[0069] When the dust cover 3 needs to be closed, the output end of the drive element 401 moves the lifting block 402 upward in a straight line. The lifting block 402 drives the drive rack 403 to move upward as well. Then, the upward-moving drive rack 403 drives the transmission gear 302 to rotate clockwise, thereby driving the rotating shaft 301 and the dust cover 3 connected to it to rotate clockwise. When it rises to the limit position, the rotating shaft 301 and the dust cover 3 connected to it rotate 180 degrees clockwise, which realizes the automatic closing of the dust cover 3, covering the sound and light alarm 2 inside to achieve dust prevention.

[0070] Example 4

[0071] This embodiment further illustrates the technical solution of the present invention based on embodiment 2 or 3.

[0072] like Figure 1 , 2 As shown in Figures 5 and 8, a guide cylinder 404 is fixed on the driving element 401, and a vertical guide rod 405 is inserted inside the guide cylinder 404. The top of the vertical guide rod 405 is fixedly connected to the lifting block 402.

[0073] The guide rod is slidably connected to the guide slide 404 fixed on the side of the drive element 401. The guide slide 404 is fixed on the side of the base of the drive element 401 and does not affect the use of the output end. The bottom of the lifting block 402 is connected to the vertical guide rod 405 and the guide slide 404, which realizes the guidance and limit of the up and down movement of the lifting block 402, improves the stability of the up and down movement, and ultimately ensures the stability of the opening and closing of the dust cover 3.

[0074] Example 5

[0075] This embodiment further illustrates the technical solution of the present invention based on Embodiment 1.

[0076] The switching mechanism 6 includes a bracket 601 with an opening on one side. The off button 603 and the on button 602 are respectively fixed on the upper and lower sides of the opening of the bracket 601. The off button 603 and the on button 602 are both electrically connected to the audible and visual alarm 2.

[0077] like Figure 2 , 3 As shown in Figure 7, in one or more specific embodiments, the bracket 601 with an opening can be a U-shaped frame or a box with a side opening. The close button 603 and the open button 602 are arranged opposite each other and are respectively set at the upper and lower ends, so that there is a gap between them. When the pressing plate 604 moves within the gap with the driving mechanism 4, pressing the close button 603 when it reaches the top and pressing the open button 602 when it reaches the bottom, so as to realize the automatic opening and closing of the sound and light alarm 2 at the same time as the dust cover 3 opens and closes.

[0078] Example 6

[0079] This embodiment further illustrates the technical solution of the present invention based on Embodiment 1.

[0080] like Figure 1 , 2 As shown in Figures 3 and 4, the system also includes a controller body 1, which is electrically connected to the drive mechanism 4, specifically to the drive element 401 in the drive mechanism 4.

[0081] The controller body 1 is provided with a support frame 102 on its top, and the audible and visual alarm 2 is detachably connected to the support frame 102. Since the audible and visual alarm 2 is detachably connected to the support frame 102, it is more convenient to disassemble it when needed. The dust cover 3 is preferably set on the side of the audible and visual alarm 2. The dust cover 3 can be rotatably connected to the support frame 102 or to the controller body 1, as long as it can cover the audible and visual alarm 2.

[0082] The detachable connection structure of the audible and visual alarm 2 is as follows:

[0083] The support frame 102 is provided with a strip-shaped bayonet 105, and the bottom of the sound and light alarm 2 is provided with an elastic buckle 204. The sound and light alarm 2 is installed on the support frame 102 by engaging the elastic buckle 204 with the strip-shaped bayonet 105.

[0084] In this embodiment, the sound and light alarm 2 and the support frame 102 are detachable by setting the elastic buckle 204 and the strip-shaped bayonet 105 to engage. During the disassembly process, since it is a snap-fit, it can be disassembled without the aid of tools, thereby improving the convenience of removing the sound and light alarm 2 from the controller body 1.

[0085] Example 7

[0086] This embodiment further illustrates the technical solution of the present invention based on Embodiment 6.

[0087] like Figure 4 As shown, the bottom of the audible and visual alarm 2 is provided with a mounting base 201. Two rectangular grooves 203 are opened on one side end face of the mounting base 201. Each rectangular groove 203 is connected to an elastic buckle 204 by a spring. The elastic buckle 204 engages with the slot 105 to fix the audible and visual alarm 2 on the support frame 102.

[0088] Specifically, the upper surface of the support frame 102 is provided with a T-shaped slide bar 104, one end of the T-shaped slide bar 104 is provided with a limiting plate 103, the bayonet 105 is opened on the limiting plate 103, and the lower surface of the mounting base 201 is provided with a T-shaped slide groove 202 that is slidably connected to the T-shaped slide bar 104.

[0089] In this embodiment, by using the cooperation of two elastic buckles 204 and the strip-shaped latch 105, when it is necessary to remove the audible and visual alarm 2 from the controller body 1, it is only necessary to manually squeeze the two elastic buckles 204 in opposite directions at the same time to separate the two elastic buckles 204 from the strip-shaped latch 105. Then, the audible and visual alarm 2 and the mounting base 201 can be slid off to the right. Moreover, since the disassembly process can be completed without the aid of tools, the disassembly of the audible and visual alarm 2 is improved.

[0090] Example 8

[0091] This embodiment further illustrates the technical solution of the present invention based on embodiment 6 or 7.

[0092] like Figure 1 , 2 As shown in Figures 3 and 8, the controller body 1 has louvered heat dissipation holes 101 on its side. In order to remove dust from the louvered heat dissipation holes 101 and ensure the heat dissipation effect of the controller, this embodiment further includes a dust removal component 5 to remove the dust attached to the louvered heat dissipation holes 101, so as to avoid affecting the ventilation and heat dissipation effect of the louvered heat dissipation holes 101, thereby improving the service life of the electronic components inside the controller body 1.

[0093] like Figure 6As shown, the dust sweeping assembly 5 includes a transmission pulley assembly, a linkage shaft 501, a rotating plate 502, a connecting rod 503, a dust sweeping brush 504, and a transverse guide rod 505. The linkage shaft 501 is linked with the rotating shaft 301 through the transmission pulley assembly. The transmission pulley assembly includes a first synchronous pulley 303 and a second synchronous pulley 506. The first synchronous pulley 303 is fixed on the rotating shaft 301, and the second synchronous pulley 506 is fixed on the linkage shaft 501. The first synchronous pulley 303 and the second synchronous pulley 506 are connected by a synchronous belt drive. The rotating plate 502 is fixedly connected to both ends of the linkage shaft 501. The dust sweeping brush 504 is provided on the outside of the louvered heat dissipation hole 101. The two ends of the dust sweeping brush 504 are slidably connected to the transverse guide rod 505. The transverse guide rod 505 is fixedly connected to the side of the controller body 1. The two ends of the connecting rod 503 are rotatably connected to the dust sweeping brush 504 and the rotating plate 502, respectively.

[0094] The transmission ratio between the first synchronous pulley 303 and the second synchronous pulley 506 is 1:2. When the first synchronous pulley 303 rotates 180°, it can drive the second synchronous pulley 506 to rotate 360°.

[0095] It should be noted that the louvered heat dissipation holes 101 are located on the side of the controller body 1, such as the left and right sides. The dust sweeping assembly 5 has two sets of transfer plate 502, connecting rod 503, and dust sweeping brush 504 to remove dust corresponding to the louvered heat dissipation holes 101 on the two sides.

[0096] As the rotating shaft 301 rotates, the first synchronous pulley 303 drives the second synchronous pulley 506 to rotate via the synchronous belt, thereby causing the linkage shaft 501 and the two circular rotating plates 502 at the end to rotate. Then, the rotating circular rotating plates 502 drive the rear end of the connecting rod 503 to rotate. Next, the front end of the connecting rod 503 carries the dust brush 504 to move back and forth along the transverse guide rod 505, thereby removing the dust attached to the louvered heat dissipation holes 101 on the left and right sides of the controller body 1.

[0097] Therefore, in this embodiment, through the cooperation of the first synchronous pulley 303 and the dust sweeping assembly 5, the two dust sweeping brushes 504 can move back and forth during the rotation of the rotating shaft 301, thereby sweeping away the dust attached to the louvered heat dissipation holes 101 on the left and right sides of the triaxial controller, avoiding affecting the ventilation and heat dissipation effect of the louvered heat dissipation holes 101, and helping to improve the service life of the electronic components inside the controller body 1.
