Description

Technical Field

[0001] The present application relates to the field of explosion-proof technology in the oil and gas industry and chemical plants, and specifically discloses a novel explosion-proof microwave induction voice risk warning device. Background Art

[0002] As an advanced alarm, microwave alarm has developed from scratch and from low-level to high-level with the development of science and technology. So far, the most advanced alarm is the microwave alarm radar (device) made based on the Doppler effect. This alarm is generally composed of a detection part and a control part. The detection part includes microwave components, Doppler amplifiers, delay circuits, identification circuits, and output circuits. The control part mainly includes signal processing, audio, light display or attached clock control, AC / DC conversion, etc. Most of the current domestic and foreign products are like this;

[0003] When working, the electromagnetic waves generated by the LC self-excited oscillation circuit are radiated to the surrounding space by the straight rod antenna, generating a three-dimensional microwave warning field. When someone moves within the range, according to the Doppler effect of the electromagnetic wave, the reflected wave of the human body will pass through the antenna to change the self-excited oscillation amplitude and frequency of the detection part. This changing fluctuation signal is amplified by the amplifier circuit and output to the comparison circuit of the control part for comparison and identification. If the identified signal is the set trigger signal, the alarm execution circuit starts to work and emits an audible and visual alarm.

[0004] Microwave alarms are non-explosion-proof alarms, have low sound levels, and have short microwave sensing distances. They pose great safety risks when used in explosion-proof areas of the oil and gas industry and chemical plants, thus limiting their scope of use. In view of this, the inventors propose a new explosion-proof microwave sensing voice risk warning device. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that traditional microwave alarms have no voice risk prompts in the field of explosion-proof technology in the oil and gas industry and chemical plants.

[0006] In order to achieve the above object, the present invention provides the following basic scheme:

[0007] A novel explosion-proof microwave induction voice risk warning device comprises a base body, a receiving groove is provided on the base body, a cylinder is provided in the receiving groove, and a microwave induction component based on a microwave alarm is provided at the protruding end of the cylinder;

[0008] The microwave induction assembly comprises a prism connected to the extended end of the cylinder, mounting grooves opened on both sides of the prism, a motor arranged at the bottom of the mounting groove, and a rotating stretching assembly connected to the motor;

[0009] The rotating stretching assembly includes a rotating rod, a retraction rope sleeved on the rotating rod, and a voice risk warning assembly arranged on one side of the rotating rod;

[0010] The prism is rotatably connected to a rotating plate on both sides of the mounting groove, a microwave alarm is arranged on the inner side of the rotating plate, a spring is arranged between the inner side of the rotating plate and the prism, and both ends of the retraction rope pass through the mounting groove and are connected to the rotating plate;

[0011] Both sides of the prism are provided with energy supply components for the microwave alarm and the voice risk warning component.

[0012] The principles and effects of this basic solution are:

[0013] 1. Compared with the existing technology, the core advantage of this device is: based on the energy supply component and voice risk warning component of the traditional microwave alarm to realize the voice risk warning function, the microwave alarm is set to fall into the warning range, so that the voice risk warning component works, and then the device can be installed in the oil and gas industry and chemical plant explosion-proof technology field, which finally solves the problem that the traditional microwave alarm does not have voice risk warning in the oil and gas industry and chemical plant explosion-proof technology field.

[0014] 2. Compared with the prior art, this device has another core advantage: the overall structure is neat and miniaturized, a base is provided, a receiving groove is opened on the base, a cylinder is provided in the receiving groove, and a microwave sensing component based on a microwave alarm is provided at the protruding end of the cylinder. When it is needed, the microwave sensing component based on the microwave alarm will be exposed through the cylinder, and when it is not needed, the microwave sensing component based on the microwave alarm will be hidden. This design realizes the miniaturization and productization of the device, and can also provide certain protection for the microwave sensing component based on the microwave alarm.

[0015] 3. Compared with the prior art, based on the second effect, this device not only realizes the protection based on the microwave sensing component of the microwave alarm, but also realizes the protection of the microwave alarm. When needed, the rotating plate will be unfolded. When not in use, the microwave alarm is hidden inside the rotating plate, thereby realizing the protection of the microwave alarm.

[0016] 4. Compared with the existing technology, this device has the effect of amplifying the voice risk warning. When the rotating plate is unfolded, a certain angle is formed between the rotating plate and the voice risk warning component. The combination of the two sets of angles can amplify the voice risk warning component, thereby ensuring that the sound of the voice risk warning can be spread over a wider range.

[0017] 5. Compared with the prior art, the function of the rotating plate is fully utilized. Not only is the microwave alarm hidden inside the rotating plate, but the angle formed by the rotating plate is also fully utilized to amplify the voice risk warning component.

[0018] Furthermore, the prism is a hexahedron, and the energy supply component is a composite structure, specifically two layers, the uppermost layer is a solar panel, and the lowermost layer is a thin-film battery connected to the solar panel, and a voltage stabilizer is provided between the solar panel and the thin-film battery. Compared with a tetrahedron, a hexahedron has more contact surfaces, which is conducive to the installation of solar panels and the conversion of solar energy, and has certain energy advantages. A thin-film battery is provided as the total energy supply, avoiding wire connection, thereby realizing the portable installation of the device.

[0019] Furthermore, the rotating rod is an intermittent rotating rod, which includes a large-diameter rotating rod and a small-diameter rotating rod. The large-diameter rotating rod and the small-diameter rotating rod are welded, and the small-diameter rotating rod is used for winding and loosening the retraction rope. The voice risk warning component is installed on the arc surface of the large-diameter rotating rod.

[0020] Furthermore, the voice risk warning component includes a sound prompt component and a buzzer, the sound prompt component includes a speaker and a voice advance recording module, a limiting groove is opened on the surface of the large-diameter rotating rod, and the voice risk warning component is modularly designed and placed in the limiting groove.

[0021] Furthermore, a protective shell for protecting the voice risk warning component is provided on the surface of the installation groove, and a plurality of holes for letting out sound are provided on the protective shell.

[0022] Furthermore, the rotating plate and the edge surface of the prism are designed to be embedded, and when the rotating plate is not working, the upper surface of the rotating plate and the surface of the prism are in the same straight line.

[0023] Furthermore, a rotating shaft is provided on the prism, and the rotating plate is connected to the rotating shaft. When the rotating plate is not working, the retraction rope is in a retracted state and the spring is in a compressed state.

[0024] Furthermore, when the retraction rope is unfolded and the spring is reset, the rotating plate is unfolded, and the angles between the rotating plates on both sides of the installation groove and the central axis of the installation groove are 45 degrees respectively.

[0025] Furthermore, the model of the microwave alarm is MA-2.

[0026] Furthermore, a base plate is provided at the bottom of the base body, and positioning holes are opened around the base plate. Positioning columns are inserted into the positioning holes. One end of the positioning column is downwardly extended to fix the base body, and the other end of the positioning column is upwardly extended to the same height as the prism. A warning rope is wrapped around and connected between adjacent positioning columns. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0033] The figure marks in the drawings of the specification include: base 1, positioning column 2, base plate 3, cylinder 4, energy supply component 6, protective shell 7, through hole 8, rotating plate 9, prism 10, rotating rod 11, winding section 1101, installation section 1102, limiting groove 1103, retraction rope 12, rotating shaft 13, spring 14.

[0034] Implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown:

[0035] A novel explosion-proof microwave induction voice risk warning device comprises a base body 1, a receiving groove is provided on the base body 1, a cylinder 4 is provided in the receiving groove, and a microwave induction component based on a microwave alarm is provided at the extended end of the cylinder 4;

[0036] like Figure 1As shown, a base plate 3 is provided at the bottom of the base body 1, and positioning holes are opened around the base plate 3. Positioning posts 2 are inserted into the positioning holes. The lower ends of the positioning posts 2 are passed downward to fix the base body 1, and the upper ends of the positioning posts 2 are passed upward to be at the same height as the prism 10. Warning ropes are wound and connected between adjacent positioning posts 2.

[0037] Specific: such as Figure 2 As shown, the microwave induction assembly includes a prism 10 connected to the extended end of the cylinder 4, mounting grooves opened on both sides of the prism 10, a motor arranged at the bottom of the mounting groove, and a rotating stretching assembly connected to the motor;

[0038] When the device is in use, the microwave sensing component is ejected from the base 1 by starting the cylinder 4. When not in use, the microwave sensing component is located inside the base 1 and is protected by the base 1. The purpose of the warning rope is that most of the devices are installed in the explosion-proof areas of the oil and gas industry and chemical plants as an alarm tool. Human touch is prohibited to ensure the stability of the function of the device.

[0039] like Figure 2 and Figure 4 As shown, the rotation stretching assembly includes a rotating rod 11, a retraction rope 12 sleeved on the rotating rod 11, and a voice risk warning assembly arranged on one side of the rotating rod 11;

[0040] Specific: such as Figure 4 As shown, the rotating rod 11 is an intermittent rotating rod 11, which includes a rotating rod 11 with a large diameter and a rotating rod 11 with a small diameter. The two rotating rods 11 are welded, and the rotating rod 11 with a small diameter is used for winding and loosening the retraction rope 12. The voice risk warning component is installed on the arc surface of the rotating rod 11 with a large diameter. Specifically, the voice risk warning component includes a sound prompt component and a buzzer, and the sound prompt component includes a speaker and a voice advance recording module. A limiting groove 1103 is opened on the surface of the rotating rod 11 with a large diameter, and the voice risk warning component is placed in the limiting groove 1103 after modular design;

[0041] Specifically: the rotating rod 11 with a large diameter is named as the installation section 1102, and the rotating rod 11 with a small diameter is named as the winding section 1101

[0042] In this embodiment, the voice risk warning component only needs to be installed on one side of the rotating rod 11. Since the rotating rod 11 will be driven to rotate by the motor, when working, the voice risk warning component will rotate to face the front, and only the rotation distance of the subsequent rotating plate 9 needs to be controlled. Here, the rotating plate 9 link will be described in detail;

[0043] like Figure 2As shown, a protective shell 7 for protecting the voice risk warning component is provided on the surface of the installation slot, and a plurality of holes 8 for sound transmission are provided on the protective shell 7. A microwave alarm is provided on the inner side of the rotating plate 9. A spring 14 is provided between the inner side of the rotating plate 9 and the prism 10. Both ends of the retraction rope 12 pass through the installation slot and are connected to the rotating plate 9.

[0044] like Figure 3 As shown, the prism 10 is located on both sides of the installation groove and is rotatably connected with a rotating plate 9. The rotating plate 9 and the prism 10 are embedded in the prism surface. When the rotating plate 9 is not working, the upper surface of the rotating plate 9 and the surface of the prism 10 are in the same straight line. Specifically: a rotating shaft 13 is provided on the prism 10, and the installation position of the rotating shaft 13 is the upper surface of the prism 10. The rotating plate 9 is connected to the rotating shaft 13. When the rotating plate 9 is not working, the retraction rope 12 is in a retracted state, and the spring 14 is in a compressed state.

[0045] Specifically: the motor controls the rotating rod 11 to rotate, so that the retraction rope 12 is no longer in a taut state. At this time, the force to overcome the reset of the spring 14 disappears, and the spring 14 pops outward, so that the rotating plate 9 is unfolded under the action of the reset of the spring 14. When the retraction rope 12 is unfolded and the spring 14 is reset, the rotating plate 9 is unfolded, and the angles between the rotating plates 9 on both sides of the installation groove and the central axis of the installation groove are 45° respectively.

[0046] At this time, it is only necessary to control the retraction length of the retraction rope 12 and the rotation distance of the rotating rod 11 in a strict design, so that when the rotating plate 9 is unfolded, all the voice risk warning components are located on the front, and when the rotating plate 9 is not unfolded, the voice risk warning component is located on the back of the rotating rod 11. This design is conducive to the protection of the voice risk warning component, improves the service life of the voice risk warning component, and avoids the influence of external factors on the work of the voice risk warning component;

[0047] Specifically: when the rotating plate 9 is unfolded, the microwave alarm located on the inner side of the rotating plate 9 is exposed, and the exposed microwave alarm can work better. In this case, the model of the microwave alarm is MA-2, and the setting range of MA-2 is 10 meters, and it is triggered within 10 meters.

[0048] About the working principle of microwave alarm:

[0049] According to the Doppler effect of electromagnetic waves, the reflected waves from the human body will pass through the antenna to change the self-oscillation amplitude and frequency of the detection part. This changing fluctuation signal is amplified by the amplifier circuit and output to the comparison circuit of the control part for comparison and identification. If the identified signal is the set trigger signal, the alarm execution circuit starts working.

[0050] Both sides of the prism 10 are provided with energy supply components 6 for supplying energy to the microwave alarm and the voice risk warning component.

[0051] Specific: such as Figure 1 and Figure 3 As shown, the prism 10 is a hexahedron prism 10, and the energy supply component 6 is a composite structure, specifically two layers, the uppermost layer is a solar panel, and the lowermost layer is a thin-film battery connected to the solar panel, and a voltage stabilizer is provided between the solar panel and the thin-film battery. Compared with a tetrahedron, the hexahedron prism 10 has more contact surfaces, which is conducive to the installation of solar panels and the conversion of solar energy, and has certain energy advantages. A thin-film battery is provided as the total energy supply, avoiding wire connection, thereby realizing the portable installation of the device.

[0052] Specific implementation process:

[0053] The first step is to better demonstrate the use of the device. A detailed description is given below: a base 1 is provided, a receiving groove is opened on the base 1, a cylinder 4 is arranged in the receiving groove, and a microwave sensing component based on a microwave alarm is provided at the protruding end of the cylinder 4. When it is needed to be used, the microwave sensing component based on the microwave alarm will be exposed through the cylinder 4. When it is not needed, the microwave sensing component based on the microwave alarm will be hidden. This design realizes the miniaturization and productization of the device, and can also provide certain protection for the microwave sensing component based on the microwave alarm.

[0054] In the second step, when the device is used, the microwave sensing component is pushed out by the cylinder 4, and the height of the microwave sensing component is changed by the cylinder 4, so that the subsequent microwave alarm can work better;

[0055] The third step is to start the motor, which rotates, so that the originally tightly wound retraction rope 12 moves in the opposite direction. During this movement, the retraction rope 12 cannot overcome the work of the spring 14, and the spring 14 is reset. The rotating plate 9 is unfolded under the action of the rotating shaft 13 and the spring 14, and the voice risk warning component on the rotating rod 11 rotates from the back to the front, so as to achieve better voice broadcasting;

[0056] The fourth step is Figure 3 As shown, it has the effect of sound amplification. When the rotating plate 9 is unfolded, a certain angle is formed between the rotating plate 9 and the voice risk warning component, which is similar to putting both hands on the mouth and shouting, which is conducive to sound amplification. The combination of two sets of angles can amplify the voice risk warning component, thereby ensuring that the sound of the sound risk warning can be spread over a wider range.

[0057] Case display:

[0058] It has been applied in the gas storage well area of ​​the natural gas comprehensive utilization station of the Yinchuan Branch of PetroChina Kunlun Gas Co., Ltd. in April 2021. The sensing range of the microwave alarm is within a radius of 10 meters, and the sensing range can be adjusted at will. When someone enters the sensing range (10-meter radius), the voice risk warning component broadcasts according to the input setting content, and the use effect is significant, realizing the "artificial intelligence safety officer" in the explosion-proof area of ​​the oil and gas industry and chemical plants to remind employees of safety precautions and risks in the installation area in real time.

[0059] The device solves the problem that traditional microwave alarms do not have voice risk warnings in the oil and gas industry and chemical plant explosion-proof technology fields.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
