Description

Technical Field

[0001] The invention relates to the technical field of ground water surface measurement, and in particular to a ground water surface measurement device based on temperature sensing technology. Background Art

[0002] A ground water accumulation measuring device based on temperature sensing technology is a device that uses a temperature sensor in combination with other sensing technologies to measure the depth of accumulated water. When measuring accumulated water, such a measuring device can use the temperature sensor to monitor the ambient temperature of the accumulated water, and use other sensors to directly measure the depth of the ground water. By comprehensively analyzing the data provided by these sensors, the system can more comprehensively evaluate the situation of ground water accumulation.

[0003] In the existing ground water measurement devices, it usually refers to a device system used to detect and record the surface water situation (such as water level, water depth and other parameters) in real time. This type of device integrates a variety of technologies, mainly including sensor technology, data acquisition and processing, wireless communication technology, and data analysis and display platform, to achieve accurate monitoring and timely warning of ground water.

[0004] However, when the sensor used in the water accumulation measuring device in the existing technology is placed in a water accumulation environment for a long time for measurement, the water will cover the sensor, causing errors in the final measurement data. When the sensor is fixed on the device and cannot be moved, the sensor will come into contact with the water every time the water accumulation is measured. The frequent contact will greatly reduce the service life of the sensor. At the same time, when the water accumulation is at a normal depth, the sensor will come into contact with the water because it cannot move. This will inevitably increase the power consumption of the sensor, resulting in deviations in the final measurement. Summary of the invention

Technical issues to be resolved In response to the deficiencies of the prior art, the present invention provides a ground water surface measuring device based on temperature sensing technology, which can preliminarily detect the depth of accumulated water by floating up a buoyancy component arranged inside the device during changes in the water level.

A buffer component is provided on the side of the sliding plate away from the sealing chamber, and the buffer component is used to buffer the accumulated water in the area contacting the temperature sensor.

[0007] Preferably, a pressure sensor is provided through the sealing chamber, and a control panel is provided inside the sealing chamber.

[0008] Preferably, an interception and filtration component is provided on the side of the sliding plate away from the buffer component, and the interception and filtration component is used to intercept the silt and pollutants carried in the accumulated water.

[0009] Preferably, the buffer assembly includes a circular filter cartridge arranged on the side of the sliding plate away from the sealing chamber, an annular cartridge arranged on the side of the sliding plate close to the circular filter cartridge, and the annular cartridge is arranged inside the circular filter cartridge and slides between the sliding plate, a screening plate arranged inside the annular cartridge, a fixed seat arranged on the side of the screening plate away from the sliding plate, and a moving rod movably arranged inside the fixed seat.

[0010] Preferably, a lifting plate is provided at one end of the movable rod away from the fixed seat, a water inlet pipe is arranged in an array on the lifting plate, an annular baffle is provided inside the annular cylinder, and the annular baffle is fixedly connected to the fixed seat, a slide groove is arranged in an array on the fixed seat, and an oblique hole is arranged in an array on the annular cylinder.

[0011] Preferably, one-way plates are arranged in an array on the annular baffle, spherical telescopic rods are symmetrically arranged on the support seat, a snap-fitting ring plate is movably arranged on one end of the spherical telescopic rod close to the one-way plate, snap-fitting grooves are symmetrically provided on one side of the one-way plate close to the snap-fitting ring plate, and a first spring is sleeved on the outside of the spherical telescopic rod.

[0012] Preferably, the intercepting filtering assembly includes a protective chamber arranged on the side of the sliding plate close to the sealing chamber, and the protective chamber wraps the pressure sensor and the temperature sensor, and also includes an oblique filter plate movably arranged on the protective chamber, a clamping plate arranged on the oblique filter plate, and a dust filter net movably arranged on the oblique filter plate, and the dust filter net and the clamping plate are in contact and fit with each other.

[0013] Preferably, a fixed cylinder is arranged in an array on one side of the oblique filter plate close to the protective bin, and a through groove is opened on the fixed cylinder, a fixed rod is arranged penetratingly arranged inside the fixed cylinder, and a lower pressure plate is arranged at one end of the fixed rod away from the fixed cylinder, and a fixed slider is arranged at one end of the fixed rod away from the lower pressure plate.

[0014] Preferably, a lifting rod is provided inside the fixed cylinder, and a matching block is provided at one end of the lifting rod close to the fixed slider, an elastic plate is provided on the side of the matching block away from the lifting rod, a second spring is provided on the side of the elastic plate close to the fixed slider, and the second spring is fixedly connected to the fixed slider.

[0015] Preferably, a fixing plate is movably provided on the lifting rod, and the fixing plate is fixedly connected to the fixing tube, a compression spring is arranged on the outer sleeve of the lifting rod, and one end of the compression spring is in contact with the matching block, a ring is arranged on the outside of the fixing tube, and the ring is located at the position of the through groove, and a telescopic spring is arranged on the side of the ring close to the fixing tube.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention cooperates with the airbag on the mounting seat. When water accumulates in the measuring area, the sliding plate is driven to float up to change the distance between the sliding plate and the top of the mounting seat to preliminarily detect the depth of the water. At the same time, the rise of the sliding plate can prevent the sensor from contacting the water when the water is at a normal depth, causing the water to cover the surrounding of the sensor, which greatly reduces the service life of the sensor. 2. At the same time, when the depth of accumulated water exceeds the entire device, the accumulated water will flow in the direction of the low terrain. In the process of the accumulated water flowing at a high speed, the measurement of the temperature sensor will be deviated. The circular filter cylinder and the annular cylinder can block the accumulated water to prevent the accumulated water from directly contacting the sensor. At the same time, the one-way plate on the water inlet pipe and the annular baffle can make the accumulated water change from lateral movement to rising, thereby turning the flowing accumulated water into relative stillness, ensuring the accuracy of the measurement data. The lifting plate set during the rising process can ensure that the lifting plate can move to the designated position through the internal cavity to open the entrance channel for the accumulated water; 3. At the same time, when the entire device is covered by accumulated water, the protective compartment outside the sensor and the dust filter on the inclined filter plate can collect and intercept the mud and dirt in the accumulated water to prevent the mud and dirt from directly contacting the sensor, causing them to adhere to the sensor surface and affect the sensitivity and measurement accuracy of the sensor. In the process of continuous movement of accumulated water with a flow rate, it is prevented from eroding the sensor and causing a decrease in the measurement accuracy of the sensor.

[0017] 4. The elastic plate arranged in the fixed cylinder cooperates with the fixed slider on the fixed rod. When the fixed rod moves, the elastic plate can be retracted inward to release the locking state between the elastic plate and the fixed cylinder, so that the collar can be reset and the locking state between the oblique filter plate and the protective bin can be released, which is convenient for the staff to replace the new dust filter and avoid excessive accumulation of dirt and sand in the dust filter, which may squeeze the sensor and cause inaccurate final measurement data.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1 See also Figures 1 to 4 , which is the first embodiment of the present invention, provides a technical solution: a ground surface water measurement device based on temperature sensing technology, comprising a mounting seat 1, an internal array of sliding grooves 11 is provided in the mounting seat 1, the sliding grooves 11 are used to limit and support the sliding plate 21, and the sliding plate 21 can be prevented from angular deflection when sliding, and a buoyancy component 2 is provided inside the mounting seat 1, and the buoyancy component 2 is used to automatically float when water accumulates on the ground; The buoyancy assembly 2 includes a sliding plate 21 disposed inside the mounting seat 1. The sliding plate 21 is a circular plate connected to a convex block. The sliding plate 21 is used to slide and engage with the sliding groove 11. Under the limit of the sliding groove 11, the buoyancy of the entire sliding plate 21 will stop when it approaches the top of the mounting seat 1. When the accumulated water does not exceed the height set by the mounting seat 1, the movement of the sliding plate 21 will measure the height of the accumulated water. A placement seat 22 is arranged on one side of the sliding plate 21. The placement seat 22 is cross-shaped and has a certain degree of elasticity, and is used to stably fix the placed airbag 23 to prevent the airbag 23 from being separated from the sliding plate 21 when it encounters rainwater with a fast flow rate. The airbag 23 arranged inside the placement seat 22 is filled with a large amount of air. When water accumulates on the ground, the airbag 23 will drive the sliding plate 21 to always float on the surface of the accumulated water under the action of the internal air. At this time, the rising of the sliding plate 21 can form a gap with the mounting seat 1 to intuitively reveal the depth of the accumulated water. A sealing chamber 24 is arranged on the side of the sliding plate 21 away from the airbag 23. The sealing chamber 24 is in the shape of a square cavity. The sealing chamber 24 is used to seal the control panel 5 connected to the pressure sensor 3 and the temperature sensor 4 to prevent the occurrence of a penetration process during the contact with the accumulated water, which causes the entire control panel 5 to fail and fail to accurately collect and transmit the signals transmitted by the two sensors; A temperature sensor 4 is provided on the sealed chamber 24, and one end of the temperature sensor 4 passes through the sliding plate 21 and is on the other side of the sliding plate 21. The temperature sensor 4 is a PT100 temperature sensor 4, which has waterproof properties and is used to prevent the temperature sensor 4 from being damaged when measuring the temperature in the accumulated water. The temperature measured by the temperature sensor 4 can be transmitted to the control panel 5, and the data of the pressure sensor 3 can be used to obtain a more accurate depth of accumulated water. A buffer component 6 is provided on the side of the sliding plate 21 away from the sealed chamber 24. The buffer component 6 is used to buffer the accumulated water in the area contacting the temperature sensor 4. When the buffer component 6 measures the depth of accumulated water, it is avoided that the temperature sensor 4 will take away part of the temperature on the surface of the temperature sensor 4 during measurement due to the excessive flow rate of the accumulated water, thereby making the final measurement data inaccurate.

[0032] A pressure sensor 3 is provided throughout the sealed chamber 24. The pressure sensor 3 is an MS5837-30BA water depth pressure sensor 3, which is used to judge the water depth according to the pressure transmitted by the accumulated water after the accumulated water gradually rises. A control panel 5 is provided inside the sealed chamber 24. The control panel 5 collects data from the two sensors through wires, and analyzes the data after the data is collected to obtain an accurate depth of accumulated water. At the same time, the entire control panel 5 is completely enclosed inside the sealed chamber 24, so that the collected data can be transmitted to the terminal for analysis at any time.

[0033] An interception and filtering component 7 is disposed on the side of the sliding plate 21 away from the buffer component 6 , and the interception and filtering component 7 is used to intercept the silt and pollutants carried in the accumulated water.

[0034] During use, the mounting base 1 is first installed in the area where water accumulation measurement is required. Then, when heavy rain occurs in the area and water accumulates, the airbag 23 arranged at the bottom of the sliding plate 21 will come into contact with the accumulated water. As the accumulated water continues to rise, the airbag 23 will drive the sliding plate 21 to always float on the surface of the accumulated water under the action of the air inside it. During the whole process, the measuring rod of the temperature sensor 4 will always be inserted into the accumulated water, and the temperature of the accumulated water will be transmitted to the control panel 5 in real time. The depth of the accumulated water can be intuitively displayed according to the continuous reduction of the distance between the floating of the sliding plate 21 and the bottom of the mounting base 1. At the same time, the temperature sensor 4 can record the initial temperature of the accumulated water and transmit it to the control panel 5, so as to cooperate with the subsequent water accumulation. When it exceeds the entire mounting base 1, the monitoring with the pressure sensor 3 transmits the data to the control panel 5, and the internal temperature of the rising accumulated water will gradually decrease with the increase of depth. When the temperature sensor 4 measures the temperature of the accumulated water, the buffer component 6 arranged on the sliding plate 21 can buffer the accumulated water with flow rate to avoid errors when measuring in the accumulated water with flow rate. At the same time, when the accumulated water applies pressure to the pressure sensor 3, it will pass through the interception filter component 7 to prevent the silt and pollutants in the accumulated water from causing errors in the results. At the same time, the two sensors will transmit the collected data to the control panel 5, and finally the control panel 5 will analyze the final depth of the accumulated water and transmit it to the final terminal for real-time monitoring by the staff.

[0035] Example 2 See also Figures 1 to 7 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: The buffer assembly 6 includes a circular filter cartridge 61 disposed on the side of the sliding plate 21 away from the sealing chamber 24. A plurality of small holes are provided on the surface of the circular filter cartridge 61 to facilitate the passage of accumulated water into the interior of the filter cartridge. Large impurities in the accumulated water can be intercepted by the circular filter cartridge 61 to prevent the impurities from entering the interior through the circular filter cartridge 61 and causing measurement errors to the temperature sensor 4. An annular cylinder 62 is disposed on the side of the sliding plate 21 close to the circular filter cartridge 61, and the annular cylinder 62 is disposed inside the circular filter cartridge 61 and slidably engaged with the sliding plate 21. A spiral groove is provided on the annular cylinder 62 to block accumulated water with a flow rate, and at the same time, the accumulated water can impact the annular cylinder 62. The brush drives the annular cylinder 62 to shake slowly, so as to reduce the error of measurement data caused by excessive scouring of accumulated water on the measuring end of the temperature sensor 4. The sieve plate 63 is arranged inside the annular cylinder 62, and the fixed seat 64 is arranged on the side of the sieve plate 63 away from the sliding plate 21. The fixed seat 64 has a cavity inside for plugging with the moving rod 65 to form a match between the fixed seat 64 and the moving rod 65. The moving rod 65 is movably arranged inside the fixed seat 64. The moving rod 65 is located in a section inside the fixed seat 64 and has a block that is engaged and slides in a slide groove 641 on the fixed seat 64. The slide groove 641 is used to limit the length of the entire moving rod 65 during the movement process.

[0036] A lifting plate 66 is provided at one end of the moving rod 65 away from the fixed seat 64. A cavity is provided inside the lifting plate 66. The cavity is used to provide the lifting plate 66 with the power to rise in the accumulated water. After the lifting plate 66 rises to the specified position and stops, it can open the entry channel for the accumulated water inside the annular cylinder 62. The accumulated water passing through this channel will greatly reduce the flow rate kinetic energy, which is convenient for the temperature sensor 4 to measure the temperature of the accumulated water. An array of water inlet pipes 67 are provided on the lifting plate 66. The end of the water inlet pipe 67 close to the sliding plate 21 is an inverted cone-shaped opening, which is used to facilitate water inlet and can increase the output aperture to further reduce the flow rate of the accumulated water. An annular baffle 68 is provided inside the annular cylinder 62, and the annular baffle 68 is fixedly connected to the fixed seat 64. An array of The through hole is used to cooperate with the one-way plate 681. The annular baffle 68 is used to prevent accumulated water from entering the area with the temperature sensor 4 through other channels and affecting the measurement of the entire temperature sensor 4. The fixed seat 64 is provided with an array of slide grooves 641. The slide grooves 641 are used to engage and slide with the moving rod 65 to facilitate the limitation of the movement of the moving rod 65. The annular cylinder 62 is provided with an array of oblique holes 621. The oblique holes 621 are located at the annular cylinder 62 near the sliding plate 21, and the oblique holes 621 have a certain inclination angle, so that when the accumulated water enters the inside of the annular cylinder 62, it can flow out through the oblique holes 621. At the same time, the oblique holes 621 can prevent the accumulated water with a flow rate from directly entering the annular cylinder 62 and causing an impact on the temperature sensor 4, thereby affecting the final measurement data.

[0037] The annular baffle 68 is provided with a one-way plate 681 in array, and the one-way plate 681 is used to open under the contact of the water inlet pipe 67, so as to open the entrance channel inside the annular cylinder 62. A support seat 682 is provided on one side of the one-way plate 681, and the one-way plate 681 is rotatably connected with the support seat 682. The support seat 682 is used to rotatably support the one-way plate 681, and the one-way plate 681 is prevented from overturning under the action of the support. Spherical telescopic rods 683 are symmetrically provided on the support seat 682. Both ends of the spherical telescopic rod 683 are spherical, and the connecting part is a telescopic rod. Under the connection action of the spherical end, it can be prevented When the one-way plate 681 is flipped, the spherical telescopic rod 683 cannot maintain the connection with the one-way plate 681. A snap-fitting ring plate 684 is movably provided at one end of the spherical telescopic rod 683 close to the one-way plate 681. The one side of the one-way plate 681 close to the snap-fitting ring plate 684 is symmetrically provided with snap-fitting grooves 6811. The snap-fitting grooves 6811 are used for snap-fitting and sliding with the snap-fitting ring plate 684. A first spring 685 is sleeved on the outside of the spherical telescopic rod 683. The first spring 685 is used to push the one-way plate 681 when the water inlet pipe 67 no longer squeezes the one-way plate 681, reset it and re-cover it on the annular baffle 68, and close the entire entrance channel.

[0038] During use, when water accumulates and continues to rise in the measurement area, the accumulated water will flow toward the low-lying direction. When the flowing accumulated water encounters the circular filter cartridge 61, the circular filter cartridge 61 will initially block the accumulated water, and then the accumulated water will enter the circular filter cartridge 61 and reach the annular cylinder 62, and perform secondary buffering on the accumulated water. At the same time, the rising accumulated water will synchronously enter the annular cylinder 62 through the bottom of the circular filter cartridge 61, and then drive the lifting plate 66 to rise under the action of the accumulated water in the cavity set in the middle of the lifting plate 66. During the rising process, the water inlet pipe 67 will squeeze the one-way plate 681 on the annular baffle 68, thereby breaking The entire water entry channel is opened to change the accumulated water with a lateral flow rate into a continuously rising mode, thereby greatly reducing the flow velocity kinetic energy carried by the accumulated water, and preventing the accumulated water with a flow rate from taking away part of the temperature on the temperature sensor 4 when measuring the accumulated water, resulting in errors in the final measurement data. At the same time, the depth of the accumulated water is analyzed in conjunction with the pressure sensor 3 to finally obtain an accurate depth of the accumulated water. When the accumulated water slowly recedes, the one-way plate 681 will, under the action of the spherical telescopic rod 683 and the first spring 685, re-cover the one-way plate 681 on the annular baffle 68 to facilitate the next measurement.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3 See also Figures 1 to 11, which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that: The interception filter assembly 7 includes a protective chamber 71 arranged on one side of the sliding plate 21 close to the sealing chamber 24, and the protective chamber 71 wraps the pressure sensor 3 and the temperature sensor 4, and also includes an oblique filter plate 72 movably arranged on the protective chamber 71, and the oblique filter plate 72 and the protective chamber 71 are fixed by plugging, which can not only ensure that the oblique filter plate 72 can be stably fixed on the protective chamber 71, but also facilitate the removal of the oblique filter plate 72 and the replacement of the dust filter net 74 installed on one side thereof, and the clamping plate 73 arranged on the oblique filter plate 72 is movably arranged on the oblique filter plate 72. The dust filter net 74 on the filter plate 72 is in contact with and fit with the clamping plate 73. When the dust filter net 74 is installed on the oblique filter plate 72, its material is flexible and has soft characteristics. Under the action of the clamping plate 73, the dust filter net 74 is dispersed into two areas. When the accumulated water passes through the dust filter net 74, the dust filter net 74 can filter the impurities in the accumulated water. Then, when the accumulated water fills the entire protective bin 71, most of the accumulated water will not continue to enter the protective bin 71, and will only apply pressure to the pressure sensor 3 through the oblique filter plate 72.

[0041] The oblique filter plate 72 is provided with a fixed cylinder 8 in an array on one side close to the protective bin 71, and a through groove 81 is opened on the fixed cylinder 8, a fixing rod 82 is provided inside the fixed cylinder 8, and a lower pressure plate 83 is provided at the end of the fixing rod 82 away from the fixed cylinder 8, the lower pressure plate 83 is used to release the locking state between the oblique filter plate 72 and the protective bin 71 when the staff applies a downward pressure force, so that the staff can replace the dust filter net 74, and a fixed slider 84 is provided at the end of the fixing rod 82 away from the lower pressure plate 83. The fixed slider 84 is a combination of a trapezoidal shape and a circular shape. When the lower pressure plate 83 is pressed downward, it can drive the fixed slider 84 to squeeze the elastic plate 87, so that the elastic plate 87 can be retracted into the fixed cylinder 8.

[0042] A lifting rod 85 is provided inside the fixed cylinder 8, and a matching block 86 is provided at one end of the lifting rod 85 close to the fixed slider 84. The matching block 86 is a cylindrical symmetrical shape with an inclined groove, and supports the elastic plate 87 under the action of the matching block 86. An elastic plate 87 is provided on the side of the matching block 86 away from the lifting rod 85. The contact points between the elastic plate 87 and the matching block 86 are two side edges, so that when the elastic plate 87 is squeezed downward by the fixed slider 84, the elastic plate 87 can shrink inward under the squeeze of the trapezoidal side edges, and the clamping relationship with the through groove 81 on the fixed cylinder 8 is released. A second spring 871 is provided on the side of the elastic plate 87 close to the fixed slider 84, and the second spring 871 is fixedly connected to the fixed slider 84. The second spring 871 is used to reset the fixed slider 84 after the fixed slider 84 completes the downward movement.

[0043] A fixing plate 851 is movably provided on the lifting rod 85, and the fixing plate 851 is fixedly connected to the fixing cylinder 8. A compression spring 852 is provided on the lifting rod 85, and one end of the compression spring 852 is in contact with the matching block 86, so that after the elastic plate 87 releases the locking relationship with the through slot 81, the structure inside the fixing cylinder 8 can be lifted as a whole by the compression spring 852. A collar 88 is provided on the outside of the fixing cylinder 8, and the collar 88 is located at the position of the through slot 81. A top block and a limit rod are provided on the collar 88 at the through slot 81, wherein the top block is used to facilitate the elastic plate 87 to apply pressure to the top block when it is inserted into the through slot 81, so that the entire collar 88 can be released. The present displacement makes it convenient for the limit rod on the collar 88 to be inserted into the corresponding opening on the protective bin 71, thereby locking the oblique filter plate 72 and the protective bin 71. A telescopic spring 881 is provided on the collar 88 near the fixed cylinder 8, and an elastic extension rod is provided at the center of the telescopic spring 881. In order to facilitate the collar 88 to not rotate at an angle due to its own gravity when moving, and to keep the collar 88 always at the same horizontal position as the through slot 81, the telescopic spring 881 is used to automatically reset the entire collar 88 when no external force is applied, so that the top block on the collar 88 can be reinserted into the through slot 81.

[0044] During use, when the accumulated water completely exceeds the protection bin 71, it will reach the inside of the protection bin 71 through the oblique filter plate 72 provided on the protection bin 71. In the process of the accumulated water continuously rising, the accumulated water exerts pressure on the pressure sensor 3, so that the pressure sensor 3 can collect data, thereby cooperating with the temperature sensor 4 to analyze the depth of the accumulated water, and the dust filter net 74 provided inside the protection bin 71 can effectively prevent impurities in the accumulated water from entering the protection bin 71. When the dust filter net 74 needs to be replaced, the staff only needs to press down the lower pressure plate 83, and under the action of the lower pressure plate 83, the fixed slider 84 at the other end of the fixed rod 82 is driven to move When the fixed slider 84 squeezes the elastic plate 87, the elastic plate 87 contracts inward and disengages from the plug-in relationship with the through slot 81. Then, under the action of the compression spring 852, the elastic plate 87 is disengaged from the initial position. Then, the ring 88 at the position of the through slot 81 on the fixed cylinder 8 will move toward the through slot 81 under the action of the telescopic spring 881. The moved ring 88 will release the locking state between the protective bin 71 and the oblique filter plate 72. After the staff replaces the new dust filter 74, the oblique filter plate 72 is placed above the protective bin 71 and pressing the lower pressure plate 83 downward again to achieve a locking state for the two, completing the entire replacement process.
