Description

Technical Field

[0001] This invention relates to the field of underwater pressure sensor technology, and more specifically, to an underwater pressure sensor installation protection device. Background Technology

[0002] An underwater pressure sensor is a device specifically designed to sense underwater pressure signals. It has the ability to efficiently convert received pressure signals into usable electrical signals according to a predetermined conversion rule. This type of sensor typically consists of two core components: a highly sensitive element responsible for capturing and responding to underwater pressure changes; and a signal processing unit responsible for processing the pressure signals captured by the sensitive element and ultimately outputting a standardized electrical signal. In the unique underwater environment, accurate pressure measurement is crucial for many fields. For example, in marine resource exploration, pressure data is needed to assess resource distribution; in underwater engineering monitoring, pressure information is a key indicator for assessing structural safety; and during ship navigation, real-time underwater pressure sensing is an important means of ensuring navigational safety.

[0003] According to patent document CN107631742A, an underwater sensor mounting and fixing mechanism is disclosed, comprising a housing and a monitoring and driving mechanism. The housing has a balancing hole and two threading ports for underwater cables to pass through and be sealed to the underwater cables. The monitoring and driving mechanism includes a sound-generating mechanism, a control unit, a first pressure sensor, a second pressure sensor, and a flexible layer wrapped around the housing. A cavity is formed between the flexible layer and the housing. A trigger pin is connected to the flexible layer. The cavity is filled with liquid. The first pressure sensor is disposed in the cavity, and the second pressure sensor is disposed in the housing. This invention provides an underwater sensor mounting and fixing mechanism for protecting cable status detection sensors, addressing the problem of easy damage to underwater cable status detection sensors.

[0004] When underwater pressure sensors are placed in various types of water bodies such as rivers, reservoirs, lakes, and canals, they may face a series of challenges posed by complex hydrological conditions. Specifically, the sensors may be impacted by strong water currents, causing them to shift and fail to remain at the predetermined measurement point. In addition, due to the siltation of sediment in the water, the sensors are easily covered or buried by sediment. In such cases, the data collected by the sensors will be severely affected, making it difficult to guarantee their accuracy and reliability, which in turn will adversely affect related hydrological monitoring and analysis work.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-4 As shown, the present invention provides an underwater pressure sensor installation protection device, including an installation protection bracket 1, a sensor connection mechanism 2 is provided on the inner top of the installation protection bracket 1, and semi-circular protective shells 3 are fixedly connected to both the left and right sides of the installation protection bracket 1, and lifting blocks 4 are fixedly connected to the middle of the top of the two semi-circular protective shells 3. When the device needs to be placed at the bottom of a lake or river, the hoisting equipment is first connected to the two hoisting blocks 4. The hoisting equipment is then used to slowly lower the entire device into the water. During the descent, the semi-circular protective shell 3 can effectively prevent underwater debris from causing collision damage to the device. After the device is lowered to the designated position at the bottom of the lake or river, the protective bracket 1 is installed and stands firmly on the bottom of the water, and the sensor connection mechanism 2 begins to work stably.

[0021] like Figure 5-8As shown, the protective bracket 1 includes a control base 11. A protective component 12 is fixedly connected to the top of the inner center of the control base 11. The control base 11 includes two side circular plates 111. A circular guide plate 112 is fixedly connected to the outer side of each of the two side circular plates 111. An electric push rod connecting block 113 is fixedly connected to the rear side of the inner center of each of the two side circular plates 111. A waterproof electric push rod 114 is fixedly connected to the inner side of each of the two electric push rod connecting blocks 113. A push-pull plate 115 is fixedly connected to the front end of the waterproof electric push rod 114. A rack rod 116 is fixedly connected to both the left and right sides of the push-pull plate 115. A guide side plate 117 is fixedly connected to the middle of the inner side of each of the two side circular plates 111. The outer walls of the two rack rods 116 are slidably connected to two guide side plates 117. On the inner side of the guide side plate 117, the inner walls of the two side circular plates 111 are rotatably connected to turntables 118. The inner walls of the two turntables 118 are fixedly connected in a circular array with central rotating block connecting rods 119. The inner sides of the left and right sets of central rotating block connecting rods 119 are fixedly connected to central rotating blocks 1111. The outer sides of the two central rotating block connecting rods 119 are fixedly connected to abutment rods 1110. The inner walls of the two central rotating blocks 1111 are fixedly connected to columnar rotating blocks 1112. The inner ends of the two columnar rotating blocks 1112 extend to the inner sides of the two side circular plates 111 and are fixedly connected to discs 1114. The bottom of the inner center of the two discs 1114 is fixedly connected to columnar crossbars 1115. The outer walls of the two columnar rotating blocks 1112 are close to the discs 1111. Gears 1113 are fixedly connected to one side of each of the two 14. The outer walls of the two gears 1113 mesh with the tops of the two rack rods 116. Scale monitoring column connecting blocks 1116 are fixedly connected to the middle of the front side of each of the two side circular plates 111. Scale monitoring columns 1117 are fixedly connected to the bottom front side of each of the two scale monitoring column connecting blocks 1116. Support components 1120 are provided on the outer sides of each of the two turntables 118. L-shaped guide blocks 1118 are fixedly connected to the front and rear sides of the bottom outer sides of each of the two side circular plates 111. Columnar upright guide blocks 1119 are fixedly connected to the bottom inner sides of the left and right sets of L-shaped guide blocks 1118. Each of the two support components 1120 includes an elliptical slide plate 11201. The inner walls of the two elliptical slide plates 11201... All are fitted onto the outer walls of the two abutment rods 1110. Columnar uprights 11202 are fixedly connected to the bottom of the middle outer side of the two elliptical sliding plates 11201. The bottom ends of the two columnar uprights 11202 extend to the bottom of the two columnar upright guide blocks 1119 and are fixedly connected to counterweight plates 11203. Multiple conical inlay blocks 11204 are fixedly connected to the bottom of the two counterweight plates 11203. Side uprights 11205 are fixedly connected to the front and rear sides of the top of the two counterweight plates 11203 on the side closest to each other. The outer walls of the two sets of side uprights 11205 are slidably connected to the inner walls of the two sets of L-shaped guide blocks 1118. Reinforcing side plates 11206 are fixedly connected to the bottom outer sides of the two sets of side uprights 11205.The bottoms of both sets of reinforcing side plates 11206 are fixedly connected to the tops of the two counterweight plates 11203; When the entire device is lowered to the bottom of a lake or river, the two counterweight plates 11203 first contact the bottom and are embedded in the silt or sand at the bottom through two sets of conical inserts 11204, providing a stable support foundation for the entire device. As the device continues to descend, the pressure on the counterweight plates 11203 gradually increases, but due to the embedding effect of the multiple conical inserts 11204 at their bottom, the device is effectively prevented from sliding or shifting. When encountering strong water currents, the silt at the bottom accumulates and rises. At this time, the two scale monitoring columns 1117 continuously monitor the height of the silt rise. When the silt rises to the preset position, the waterproof electric push rod 114 is activated, which, through the push-pull plate 115, drives... The moving rack 116 moves inward along the guide side plate 117. The movement of the rack 116 drives the gear 1113 meshing with it to rotate. The rotation of the gear 1113 drives the columnar rotating block 1112 and the disk 1114 to rotate. The columnar crossbar 1115 is then lifted upward. The rotation of the two columnar rotating blocks 1112 causes the central rotating block 1111 to rotate. The rotation of the central rotating block 1111 drives the turntable 118 to rotate synchronously through the multiple central rotating block connecting rods 119 fixed to the outer wall. The central rotating block connecting rods 119 also drive the abutment rod 1110 to rotate. The rotation of the abutment rod 1110 pushes the elliptical slide plate 11201 on the outer wall to move downward. Since the two protective components 12 are inlaid... Embedded at the bottom, when the abutment rod 1110 rotates and pushes the elliptical slide plate 11201 downward, the elliptical slide plate 11201 will drive the columnar upright 11202 and the counterweight plate 11203 to make a slight downward adjustment as a whole. This slight adjustment can further increase the grip of the device without compromising the stability of the conical inlay block 11204 and the bottom silt or sand. During the downward adjustment of the counterweight plate 11203, the side upright 11205 slides downward along the inner wall of the L-shaped guide block 1118 to ensure the smooth movement of the counterweight plate 11203. At the same time, the reinforced side plate 11206 plays an auxiliary support role to prevent the counterweight plate 11203 from moving downward. When the device tilts, the overall stability of the device on the bottom of the water is significantly improved after the counterweight plate 11203 is adjusted to the appropriate position. Even under the continuous impact of strong water flow, the counterweight plate 11203 can effectively fix the device and ensure the stable operation of the device. At the same time, the control base 11 moves upward with the rotation of the push rod 1110 and the push of the two columnar uprights 11202. The scale monitoring column 1117 also moves upward accordingly. The scale markings on the scale monitoring column 1117 can clearly reflect the position change of the device relative to the bottom of the water, which makes it convenient for operators to understand the operating status of the device in a timely manner. The control base 11 moves upward and gets away from the silt layer. The waterproof electric actuator 114 extends and retracts at a fixed distance each time, thus fixing the movement distance of the rack rod 116. This precise control mechanism ensures the stability and reliability of the entire device during adjustment. With a preset travel length, the pressure sensor body 25 rises by 20 centimeters each time. During device operation, the pressure sensor body 25 remains in the core monitoring position, enabling it to sense underwater pressure changes in real time.

[0022] like Figure 9-10 As shown, the protective assembly 12 includes two guide side uprights 121. The outer sides of both guide side uprights 121 are fixedly connected to the top of the middle inner side of two side circular plates 111. L-shaped side connecting plates 122 are fixedly connected to the top rear side of both guide side uprights 121. Upright plates 123 are fixedly connected to the inner sides of the two L-shaped side connecting plates 122. The bottom front side of upright plates 123 is fixedly connected to the bottom rear side of the two side circular plates 111. A columnar protective shell connecting block 124 is fixedly connected to the top front side of upright plates 123. A columnar protective shell 125 is fixedly connected to the front side of the columnar protective shell connecting block 124. The bottom of the columnar protective shell 125 has a hollow design, allowing the sensor to pass through. The connecting mechanism 2 includes a sensor connecting block 21. Push-pull side plates 22 are fixedly connected to both the left and right sides of the sensor connecting block 21. The bottom of each of the two push-pull side plates 22 is fixedly connected to a second elliptical slide plate 23. The inner walls of the two second elliptical slide plates 23 are fitted onto the left and right sides of the outer wall of the columnar crossbar 1115. The top of the middle part of the outer side of each of the two push-pull side plates 22 is fixedly connected to a side plate slider 24. The outer walls of the two side plate sliders 24 are slidably connected to the inner side of the two guide side plates 121. The top middle part of the sensor connecting block 21 is fixedly connected to a pressure sensor body 25. The top of the pressure sensor body 25 is aligned with the bottom of the columnar protective shell 125.

[0023] As the two discs 1114 rotate, driving the columnar crossbar 1115 to rotate, the columnar crossbar 1115 rotates, which in turn drives the two second elliptical sliding plates 23 to slide upward. Since the second elliptical sliding plates 23 are fixedly connected to the push-pull side plate 22, and the push-pull side plate 22 is slidably connected to the guide side plate 121 through the side plate slider 24, this sliding ensures that the sensor connecting block 21 moves smoothly in the horizontal direction without deviation or shaking. The smooth movement of the sensor connecting block 21 ensures that the pressure sensor body 25 fixed at its top can always remain aligned with the bottom of the columnar protective shell 125. The pressure sensor body 25 moves upward and further away from the silt layer, avoiding contact with the silt. To prevent corrosion or data interference, when the water flow is too strong or the underwater environment is too harsh, requiring further protection of the pressure sensor body 25 or overall device recovery, the waterproof electric push rod 114 increases its operating stroke. The push-pull plate 115 continues to drive the rack rod 116 to move, driving the gear 1113 to rotate further, causing the columnar rotating block 1112 and the disc 1114 to rotate continuously. The columnar crossbar 1115 continues to rise under the drive of the disc 1114. The second elliptical slide plate 23, through the cooperation of the push-pull side plate 22 and the side plate slider 24, makes the sensor connecting block 21 rise smoothly, and the pressure sensor body 25 quickly moves into the interior of the columnar protective shell 125, providing reliable physical protection for the pressure sensor body 25.

[0024] Working principle of this invention: When it is necessary to place the underwater pressure sensor at the bottom of a lake or river, firstly, two lifting blocks 4 are connected to a lifting device. The lifting device is then used to slowly lower the entire device into the water. As the device descends to the bottom of the lake or river, the two counterweight plates 11203 first contact the bottom and are embedded in the silt or sand at the bottom by two sets of conical inserts 11204, providing a stable support foundation for the entire device. As the device continues to descend, the pressure on the counterweight plates 11203 gradually increases, but due to the embedding effect of the multiple conical inserts 11204 at their bottom, the device is effectively prevented from sliding or shifting. When encountering strong water currents, the silt at the bottom accumulates and rises, at which point the two scale monitoring columns 1117 continuously monitor the pressure. When the silt rises to a preset position, the waterproof electric push rod 114 is activated. This push-pull plate 115 drives the rack rod 116 to move inward along the guide side plate 117. The movement of the rack rod 116 drives the meshing gear 1113 to rotate. The rotation of the gear 1113 causes the columnar rotating blocks 1112 and the disc 1114 to rotate, lifting the columnar crossbar 1115 upward. The rotation of the two columnar rotating blocks 1112 causes the central rotating block 1111 to rotate. The rotation of the central rotating block 1111, through multiple central rotating block connecting rods 119 fixed to the outer wall, drives the turntable 118 to rotate synchronously. These connecting rods, in turn, drive the abutment rod 1110 to rotate. The rotation of the abutment rod 1110 then pushes the elliptical sliding groove plate 1 on the outer wall. As 1201 moves downwards, since the two protective components 12 are embedded in the bottom of the water flow, when the abutment rod 1110 rotates and pushes the elliptical slide plate 11201 downwards, the elliptical slide plate 11201 will drive the columnar upright 11202 and the counterweight plate 11203 to make a slight downward adjustment as a whole. This slight adjustment can further increase the grip of the device without compromising the stability of the conical inlay block 11204 embedded in the silt or sand at the bottom of the water. At the same time, as the abutment rod 1110 rotates, the control base 11 will also move upwards as the two columnar uprights 11202 push it. The scale monitoring column 1117 will also move upwards accordingly. The scale markings on the scale monitoring column 1117 can clearly reflect the device relative to the bottom of the water flow. The change in underwater position allows operators to promptly understand the device's operating status. The control base 11 moves upwards, detaching from the accumulated silt layer. Simultaneously, the rotation of the two discs 1114 drives the columnar crossbar 1115 to rotate, which in turn causes the two second elliptical sliding plates 23 to slide upwards. This moves the pressure sensor body 25 upwards, further away from the silt layer, preventing corrosion or data interference that could result from contact with the silt. When the water flow is too strong or the underwater environment too harsh, requiring further protection of the pressure sensor body 25 or overall device recovery, the waterproof electric push rod 114 increases its stroke. The push-pull plate 115 continues to move the rack rod 116, further rotating the drive gear 1113.The cylindrical rotating block 1112 and the disc 1114 continue to rotate, and the cylindrical crossbar 1115 continues to rise under the action of the disc 1114. The second elliptical sliding plate 23, through the cooperation of the push-pull side plate 22 and the side plate slider 24, causes the sensor connecting block 21 to rise smoothly. The pressure sensor body 25 then quickly moves into the cylindrical protective shell 125, providing reliable physical protection for the pressure sensor body 25.
