Description

Technical Field

[0001] The present invention relates to the technical field of rescue operation platforms, and in particular to an environmental monitoring device for a rescue operation platform. Background Art

[0002] The rescue operation platform is an important place for emergency medical treatment. Environmental monitoring can understand the environmental quality, microbial concentration and other indicators in the platform in real time, mainly including the monitoring of gas concentrations such as O2, CO2, H2S, CO, the monitoring of suspended particles and microorganisms, and the monitoring of parameters such as temperature, humidity and air pressure. Through monitoring, potential pollution sources can be detected in time, effective disinfection measures can be taken to prevent the occurrence of cross-infection, the health of patients and medical staff can be guaranteed, and all-round environmental safety guarantee can be provided for medical rescue.

[0003] Especially in major disasters such as earthquakes, fires or explosions, due to the unstable treatment environment, environmental monitoring of the rescue operation platform is even more important. The common outdoor rescue operation platform is a vehicle-mounted operation platform, that is, a mobile cabin. At present, the environmental monitoring equipment in the mobile cabin generally adopts fixed monitoring, that is, the environmental monitoring equipment is fixedly installed on the wall or ceiling, with a small monitoring range and unable to reflect the environmental quality of the entire operation space, or manual monitoring with a hand-held monitoring device. Manual monitoring generally has a short time and can only reflect the environmental quality at a certain time point, generating monitoring data with time as the horizontal axis, that is, the A-display waveform, and unable to continuously monitor the environmental quality at different spatial positions, that is, unable to generate the B-display waveform. In a fire or explosion scene, the spatial environment changes continuously, and continuous monitoring is required to take different measures to deal with different environmental conditions; there are also rescue operation platforms that, in order to achieve dead-angle-free monitoring, install multiple identical monitoring devices at different positions to monitor the environmental quality at different position points to ensure the representativeness and reliability of the monitoring data. However, installing multiple monitoring devices greatly increases the medical cost, and the large number of monitoring devices occupies a large space, making the operation space cramped, and the data viewing and analysis are also cumbersome, wasting the energy and time of medical staff.

[0004] Therefore, the present application provides an environmental monitoring device for a rescue operation platform to solve the problems raised in the above background art. Summary of the Invention

[0005] The purpose of the present invention is to provide an environmental monitoring device for a rescue operation platform, which solves the problems of limited monitoring range of fixed points in the existing rescue operation platform or monitoring by multiple monitoring devices, high cost, and generally short time of manual monitoring, which can only generate the A-display waveform, etc.

[0006] To solve the above technical problems, the present invention provides an environmental monitoring device for a rescue operation platform, which includes two folding electric cylinders. The vertical distance between the two folding electric cylinders is fixed on the ceiling of the mobile medical cabin. The lower ends of the telescopic rods of the folding electric cylinders are respectively axially connected to support plates. A parallel bar is horizontally arranged between the two support plates, and both ends of the parallel bar are fixed on the support plates. A slider assembly is movably sleeved on the parallel bar body, and a monitoring module is arranged on the bottom surface of the slider assembly for environmental monitoring of the rescue operation platform.

[0007] A further improvement of the technical solution of the present invention is that the parallel bar further includes two parallel sliding rods, and both ends of the sliding rods are adaptively screwed into the threaded holes of the support plates.

[0008] A further improvement of the technical solution of the present invention is that the slider assembly further includes a bottom plate, the bottom plate is approximately square, and several mounting holes are arranged in the middle of the bottom plate for mounting and fixing the monitoring module.

[0009] A further improvement of the technical solution of the present invention is that four sliders are symmetrically arranged at the four corners on the top surface of the bottom plate, and two sliders on the same side penetrate through the same sliding rod body.

[0010] A further improvement of the technical solution of the present invention is that the slider further includes a cube-shaped housing, a through hole is arranged in the middle of the housing, a fixed sleeve is abutted against the inner wall of the through hole cavity, a track cylinder is sleeved in the fixed sleeve, several annular tracks are arranged on the inner wall of the track cylinder, and several ball bearings are adaptively installed in the annular tracks.

[0011] A further improvement of the technical solution of the present invention is that the depth of the annular track is 2 / 3 to 4 / 5 of the diameter of the ball bearing.

[0012] A further improvement of the technical solution of the present invention is that lock rings are arranged at both ends of the through hole cavity for fixing the track cylinder and the fixed sleeve.

[0013] A further improvement of the technical solution of the present invention is that an encoder is arranged on the top surface of the bottom plate, the circumferential surface of the code disk of the encoder is in an inward concave arc shape, and the circumferential surface of the code disk is adaptively abutted against the outer wall of the sliding rod.

[0014] A further improvement of the technical solution of the present invention is that the support plate is approximately triangular, threaded holes are symmetrically arranged on both sides of the lower part of the support plate, and the pin at the top of the support plate is axially connected to the bottom end of the telescopic rod.

[0015] A further improvement of the technical solution of the present invention is that the length of the parallel bar is 2 to 5 m, and the inclination angle of the parallel bar is 0 to 10°.

[0016] A further improvement of the technical solution of the present invention is that the monitoring module further includes a multi-parameter gas monitoring module, a floating and sinking and microorganism monitoring module, a meteorological integrated monitoring module, etc.

[0017] Adopting the above technical solutions, the present invention has the following beneficial effects: 1. An environmental monitoring device for a rescue operation platform provided by the present invention. The slider assembly is movably sleeved on the parallel bars. By converting the micro-vertical displacement of the telescopic rod of the folding electric cylinder into the angular inclination of the parallel bars, the sliding assembly can freely slide on the parallel bars under the action of gravity, enabling the monitoring device fixed on the bottom plate to have an increased monitoring range and realizing the monitoring of the entire mobile cabin by moving back and forth. Compared with the limitations of traditional fixed monitoring devices, the device achieves full spatial coverage through dynamic patrol monitoring, avoids monitoring blind spots, and improves the comprehensiveness of monitoring.

[0018] 2. An environmental monitoring device for a rescue operation platform provided by the present invention. The sliding assembly fixes the bottom plate through four sliders, and the four sliders respectively penetrate through a slide rod body in pairs. This not only reduces the mechanical vibration interference during the movement of the device but also ensures the stability of the overall structure. The reciprocating movement of the slider assembly on the parallel bars forms a three-dimensional monitoring network. Compared with fixed monitoring, the coverage rate of mobile monitoring is greatly improved, and the gradient changes of temperature, air pressure, microbial concentration, etc. can be captured in real time. Especially in the monitoring of aerosol transmission, the pathogen capture efficiency of mobile detection is increased by 42%, which is of crucial significance for preventing surgical infections.

[0019] 3. An environmental monitoring device for a rescue operation platform provided by the present invention. A number of annular ball bearings are precisely arranged inside the slider, and the ball bearings form point-contact rolling friction with the parallel bar track. Compared with the traditional sliding friction mechanism, the friction coefficient is reduced, making the slider slide smoothly on the parallel bars, and largely eliminating the sliding noise. At the same time, the speed stability is improved, and a uniform speed of 0.01 m / s can still be maintained when the parallel bars are inclined at 5°, avoiding data acquisition distortion caused by inertial errors.

[0020] 4. An environmental monitoring device for a rescue operation platform provided by the present invention. The annular track makes the ball load evenly distributed through a 360° closed-loop structure, avoiding movement jamming caused by local deformation. When the ball bearings circulate and roll in the closed track, they can automatically compensate for the lateral force offset caused by the inclination of the parallel bars, and the measured fluctuation amplitude of the movement track is less than 0.03 mm / m.

[0021] 5. An environmental monitoring device for a rescue operation platform provided by the present invention. The retractable electric cylinder, the encoder, and the monitoring device are all electrically connected to an external control system (such as the PLC terminal) to automatically control the running speed of the retractable electric cylinder and the extending stroke of the telescopic rod. At the same time, the encoder obtains the displacement and position information of the monitoring module by rolling the code disk on the double bars and transmits this information to the PLC terminal. The PLC terminal generates a B-display waveform image based on the position information of the monitoring module and the A-display waveform. There is only an A-display waveform for fixed-point monitoring. The present invention can generate a monitored B-display image. Through the B-display waveform technology, the environmental monitoring inside the mobile medical cabin can achieve more intuitive and accurate imaging and analysis, providing strong support for medical staff to accurately and effectively supervise the rescue operation platform.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] The present invention will be further explained below in conjunction with specific embodiments.

[0029] Such as Figures 1-8As shown in the figure, an environmental monitoring device for a rescue operation platform provided in this embodiment includes two folding electric cylinders 1. The vertical distance between the two folding electric cylinders 1 is fixed on the ceiling of the mobile medical cabin 2. The lower ends of the telescopic rods 11 of the folding electric cylinders 1 are respectively axially connected to the support plates 3. A parallel bar 4 is horizontally arranged between the two support plates 3. Both ends of the parallel bar 4 are fixed on the support plates 3. A slider assembly 5 is movably sleeved on the body of the parallel bar 4. A monitoring module 6 is arranged on the bottom surface of the slider assembly 5 and is used for environmental monitoring inside the mobile medical cabin 2. Specifically, the folding electric cylinder 1 is an existing product on the market, preferably an electric telescopic rod 11. The slider assembly 5 is movably sleeved on the parallel bar 4. The telescopic rod 11 of the folding electric cylinder 1 is provided with a travel scale. When a slight vertical displacement occurs in the telescopic rod 11 on one side, it drives the parallel bar 4 to tilt at an angle, causing the slider assembly 5 to slowly slide towards one end of the parallel bar 4 under the action of gravity, increasing the monitoring range of the monitoring module 6 fixed on the bottom plate 51, realizing the reciprocating movement of the monitoring module 6 in the entire length direction of the mobile medical cabin 2, and achieving the back-and-forth mobile monitoring inside the entire mobile medical cabin 2. Compared with the limitations of traditional fixed monitoring devices, this device achieves full spatial coverage through dynamic patrol measurement, avoids monitoring blind spots, and improves the comprehensiveness of monitoring. At the same time, the folding electric cylinder 1, the encoder 7, and the monitoring module 6 are all electrically connected to an external control system (such as a PLC terminal). Among them, the folding electric cylinder 1, the encoder 7, and the PLC are existing devices and technologies, and the specific working principles will not be elaborated here. The PLC sends a pulse signal to the servo driver through the high-speed pulse output module to control the rotation speed of the motor and the travel and speed of the telescopic rod 11. The encoder 7 directly feeds back data to the PLC through the driver for monitoring the actual position and moving speed of the monitoring module 6. The monitoring module 6 transmits the monitoring data to the PLC terminal through the wireless network signal. The PLC terminal generates a B-display waveform image based on the position information of the monitoring module 6 and the A-display waveform, which can realize more intuitive and accurate imaging and analysis of the environmental monitoring data inside the mobile medical cabin 2, providing strong support for medical staff to accurately and effectively supervise the rescue operation platform.

[0030] As Figures 1-3As shown in the figure, in this embodiment, the parallel bars 4 further include two sliding rods 41 arranged in parallel. The two ends of the sliding rods 41 are adaptively screwed into the threaded holes 31 of the support plates 3. The length of the parallel bars 4 is 2 to 5 m, and the inclination angle of the parallel bars 4 is 0 to 10°. The slider assembly 5 further includes a bottom plate 51. The bottom plate 51 is approximately square. A plurality of mounting holes 511 are provided in the middle of the bottom plate 51 for mounting and fixing the monitoring module 6. Four sliders 52 are symmetrically arranged at the four corners on the top surface of the bottom plate 51. Two sliders 52 on the same side penetrate through the body of the same sliding rod 41. Specifically, the parallel bars 4 are made of stainless steel and are hollow tubular bodies, which reduce the weight while ensuring the support strength. The length of the parallel bars 4 is 3 m, which is close to the length of the inner space of the mobile medical cabin 2. The parallel bars 4 are hung in the middle of the width direction of the mobile medical cabin 2 through the folding electric cylinder 1 and the support plates 3 and are parallel to the ceiling of the mobile medical cabin 2. Two sliders 52 are movably and adaptively sleeved on each sliding rod 41 of the parallel bars 4. A bottom plate 51 is fixedly installed under the sliders 52. The bottom plate 51 is used for installing the encoder 7 and the monitoring module 6. Among them, the monitoring module 6 is electrically connected to the monitoring equipment. The monitoring module 6 includes a multi-parameter gas monitoring module 6 (real-time monitoring of gas concentrations such as O2, CO2, H2S, CO, etc.), a floating and microbial monitoring module 6 (monitoring suspended particles and microorganisms), and a meteorological integrated monitoring module 6 (monitoring parameters such as temperature, humidity, and air pressure), etc. Through the cooperation of these monitoring modules 6, the encoder 7, and the PLC terminal, a B-mode image can be generated, making the environmental monitoring data in the mobile medical cabin 2 more intuitive, more accurate imaging and analysis, facilitating medical staff to quickly understand the environmental conditions in the mobile medical cabin 2, so as to quickly adopt effective response plans.

[0031] As Figures 4-6 shown in the figure, in this embodiment, the slider 52 further includes a cubic housing 521. A through hole cavity 522 is provided in the middle of the housing 521. A fixed sleeve 523 is abutted and arranged in the through hole cavity 522. A track cylinder 524 is sleeved in the fixed sleeve 523. A plurality of annular tracks 525 are provided on the inner wall of the track cylinder 524. A plurality of balls 526 are adaptively installed in the annular tracks 525. The depth of the annular track 525 is 2 / 3 to 4 / 5 of the diameter of the ball 526. Lock rings 527 are provided at both ends of the through hole cavity 522 for fixing the track cylinder 524 and the fixed sleeve 523. Specifically, the annular track 525 enables the load of the balls 526 to be evenly distributed through a closed-loop structure, avoiding motion jamming caused by local deformation. When the balls 526 circulate and roll in the closed annular track 525, the lateral force offset caused by the inclination of the parallel bars 4 can be automatically compensated. The measured fluctuation amplitude of the motion trajectory is less than 0.03 mm / m, realizing low-friction and high-precision motion control. At the same time, the balls 526 are in point contact with the parallel bars 4, and the contact area is small. The contact area between the balls 526 and the parallel bars 4 is only 0.78 mm² (1 / 120 of the traditional surface contact), and the friction heat generation rate is reduced by 82%. The service life can be extended to 1200 km by cooperating with silicon nitride ceramic balls 526.

[0032] As Figure 2 , Figure 7 shown, in this embodiment, an encoder 7 is provided on the top surface of the bottom plate 51. The circumferential surface of the code disk 71 of the encoder 7 is an inwardly concave arc surface, and the circumferential surface of the code disk 71 is adapted to abut against the outer wall of the slide rod 41. Specifically, the circumferential surface of the code disk 71 is an inwardly concave arc surface that abuts against the outwardly convex arc surface of the slide rod 41, increasing the contact area between the code disk 71 and the slide rod 41, better recording the travel distance, preventing the encoder 7 from skipping numbers. The encoder 7 obtains the displacement and position information of the monitoring module 6 through the rolling of the code disk 71 on the parallel bars 4, and transmits this information to the PLC terminal. The PLC terminal generates a B-display image according to the position information of the monitoring module 6 and the A-display waveform. There is only an A-display waveform for fixed-point monitoring. The present invention can generate a monitored B-display image. Through the B-display waveform technology, the environmental monitoring in the mobile medical cabin 2 can achieve more intuitive and accurate imaging and analysis, providing strong support for medical staff to accurately and effectively supervise and rescue the operation platform.

[0033] As Figure 2 , Figure 8 shown, in this embodiment, the support plate 3 is triangular in shape, and threaded holes 31 are symmetrically provided on both sides of the lower part of the support plate 3. The pin 32 at the top of the support plate 3 is axially connected to the bottom end of the telescopic rod 11. Specifically, a circular ring shaft is provided at the bottom end of the telescopic rod 11 of the folding electric cylinder 1, and this circular ring shaft is movably sleeved on the body of the pin 32 at the top of the support plate 3. When the telescopic rod 11 of the folding electric cylinder 1 at one end extends downward, it simultaneously drives the same-side end of the parallel bars 4 to move downward, causing the support plate 3 at the other end to rotate around the circular ring shaft towards the parallel bars 4 and present an inwardly inclined state, with the parallel bars 4 showing one end low and one end high. Under the action of gravity, the ball 526 of the slider 52 on the slider assembly 5 slides uniformly on the parallel bars 4 towards the lower end.

[0034] The working principle of an environmental monitoring device for a rescue operation platform provided by the present invention is as follows: During use, the staff sets the movement interval and movement speed of the telescopic rod 11 of the folding electric cylinder 1 through an external control system (such as a PLC terminal, a host, and a handheld terminal), and starts the folding electric cylinder 1 at one end through an external system (such as a PLC terminal). The telescopic rod 11 extends downward, driving one end of the parallel bars 4 to move downward, and the support plate 3 at the other end rotates around the axis to an inwardly inclined state, making the parallel bars 4 have one end lower and the other end higher. The slider assembly 5 slides towards the lower end of the parallel bars 4. When it slides to the lowest end of the parallel bars 4, the telescopic rod 11 of the folding electric cylinder 1 at the lowest end retracts upward, and the parallel bars 4 return to the horizontal state. Immediately afterwards, the telescopic rod 11 of the folding electric cylinder 1 at the other end extends downward, driving the other end of the parallel bars 4 to tilt downward, and at the same time, the support plate 3 at the opposite end rotates around the axis to an inwardly inclined state, and the slider assembly 5 slides towards the other end of the parallel bars 4. The slider assembly 5 makes a reciprocating motion on the parallel bars 4 according to the above process, driving the monitoring module 6 to monitor the entire mobile medical cabin 2 without dead angles; the operation speed of the folding electric cylinder 1 and the extension stroke of the telescopic rod 11 are automatically controlled through an external control system (PLC terminal). At the same time, the encoder 7 obtains the displacement and position information of the monitoring module 6 by rolling the code disk 71 on the parallel bars 4, and transmits this information to the corresponding monitoring equipment. (PLC terminal) generates a B-display image based on the position information and A-display waveform of the monitoring module 6. There is only an A-display waveform for fixed-point monitoring. The present invention can generate a monitored B-display image. Through the B-display waveform technology, the environmental monitoring inside the mobile medical cabin 2 can achieve more intuitive and accurate imaging and analysis, providing strong support for medical staff to accurately and effectively supervise the rescue operation platform.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
