[0015] The sand and gravel in the water flow are intercepted and isolated by the isolation net to prevent the sand and gravel in the water from colliding with the sensor group under the influence of the water flow, causing damage to the sensor group and affecting the collection of underwater data. At the same time, the sand and gravel intercepted on the surface of the isolation net can be transferred to the rear of the sensor group through the rotation of the isolation net, that is, the sand and gravel intercepted on the surface of the isolation net can be transferred to the rear of the sensor group, that is, the sand and gravel intercepted on the surface of the isolation net can be transferred in the opposite direction of the water flow, and then driven by the water flow, the sand and gravel on the isolation net behind the sensor group can be carried away, so as to prevent the accumulation of sand and gravel on the surface of the isolation net and affect the monitoring and collection effect of the sensor group.

[0016] By raising the underwater hydrophone from the middle of the installation top plate, the detection end of the underwater hydrophone is moved away from the isolation net, thereby preventing the isolation net from affecting the underwater vibration and noise collection of the underwater hydrophone; and, through the buffer water bag, the vibration generated by the impact and collision of the isolation net by the water flow and the sand and gravel in the water flow can be buffered and absorbed, thereby reducing the impact of the equipment's own vibration on the underwater hydrophone, which is beneficial to improving the accuracy of the underwater hydrophone in collecting and detecting underwater vibration and noise.

[0017] The blades also disrupt the water flow toward the isolation net, causing part of the water flow to flow away from the side of the isolation net, preventing the water flow and the sand and gravel carried in the water flow from directly hitting the isolation net, thereby reducing the impact force of the water flow and the sand and gravel in the water flow on the isolation net, thereby reducing the external force on the entire device, allowing the underwater hydrophone to work more stably, further helping to improve the accuracy of data collection.

[0018] By controlling the multi-stage electric push rod to drive the circular plate and the underwater hydrophone to move, the underwater hydrophone can be moved down into the cylinder for protection, thereby making the underwater hydrophone have a protective function to prevent the underwater hydrophone from being easily damaged during continuous working underwater; and the buffer water bag can buffer the vibration of the isolation net caused by the impact and collision of the water flow and the sand and gravel in the water flow, reduce the influence of the equipment's own vibration on the underwater hydrophone, and can effectively improve the underwater hydrophone's collection and detection of underwater vibration noise.

[0028] It also includes an electric slip ring 6, an isolation net 7, a rib rod 71, a cylinder 101, a multi-stage electric push rod 102, a circular plate 103 and an underwater hydrophone 104; an electric slip ring 6 is fixedly connected to each of the mounting top plate 1 and the mounting bottom plate 3; the rotating parts of the two electric slip rings 6 are connected to an isolation net 7 through a connecting block, and a plurality of rib rods 71 ​​are arranged on the isolation net 7 to enhance the stability of the isolation net 7; a cylinder 101 is fixedly connected to the bottom of the mounting top plate 1, and the cylinder 101 is located on the inner side of the mounting block 4, and the cylinder 101 does not contact the mounting block 4, and the cylinder 101 is set to be hollow shape; a rotating ring 10101 is rotatably connected to the bottom of the cylinder 101; the rotating ring 10101 is fixedly connected to two multi-stage electric push rods 102; all the telescopic parts of the multi-stage electric push rods 102 are commonly fixedly connected to a circular plate 103, and the outer ring surface of the circular plate 103 is in contact with the inner wall of the cylinder 101; the circular plate 103 is bolted to an underwater hydrophone 104, and the underwater hydrophone 104 is located in the hollow of the cylinder 101; the mounting top plate 1 is opened with a connecting hole 02, and the connecting hole 02 is connected to the hollow of the cylinder 101; the connecting hole 02 is rotatably connected to a cover plate 03 through a torsion spring.

[0029] It also includes compression springs 8; five compression springs 8 are fixedly connected to the connecting block of each rotating part of the electric slip ring 6, and the compression springs 8 are fixedly connected to the rib rods 71, and the rib rods 71 ​​are slidably connected to the connecting block of the rotating part of the electric slip ring 6.

[0030] It also includes blades 9; five blades 9 distributed in a ring array are fixedly connected to the surface of the isolation net 7.

[0031] It also includes an elastic cloth 10; an elastic cloth 10 is fixedly connected to the connecting block of the rotating part of each electric slip ring 6, and the elastic cloth 10 is fixedly connected to the isolation net 7. The elastic cloth 10 is used to shield the connecting position between the electric slip ring 6 and the isolation net 7 to prevent sand and stones in the water from entering the isolation net 7 from between the two and causing damage to the internal sensor group 5.

[0032] It also includes a buffer water bag 105 ; three buffer water bags 105 are fixedly connected to the surface of the cylinder 101 , and all the buffer water bags 105 are fixedly connected to the mounting block 4 .

[0033] It also includes bristles 106; a plurality of bristles 106 are fixedly connected to the hollow part of the cylinder 101; a clamping rod 10301 is provided at the bottom of the circular plate 103, and the clamping rod 10301 passes through the rotating ring 10101; the electric slip ring 6 is provided with a clamping plate 601, and the clamping plate 601 and the clamping rod 10301 are mutually clamped.

[0034] A rubber gasket is provided at the contact position between the circular plate 103 and the cylinder 101, a rubber gasket is provided at the contact position between the rotating ring 10101 and the clamping rod 10301, and a rubber gasket is provided at the contact position between the rotating ring 10101 and the cylinder 101, so that the circular plate 103 and the rotating ring 10101 are in a sealed state to prevent external water from contacting the electrical components of the multi-stage electric push rod 102 and the underwater hydrophone 104, thereby ensuring the normal operation of the multi-stage electric push rod 102 and the underwater hydrophone 104.

[0035] The isolation net 7 is configured as an elastic net, which can buffer and absorb the impact force when impacted, thereby improving the stability of the equipment underwater.

[0036] During operation, the connecting rod is first manually fixed to the connecting portion 01 of the mounting top plate 1 by bolts, and then the mounting top plate 1 and other connected parts on the mounting top plate 1 are manually lowered into the water, and the connecting rod is rotated so that the sensor group 5 faces the direction of the water flow. When the sensor group 5 on the mounting block 4 enters underwater, the sensor group 5 is controlled to work, and various underwater data of the river are detected and collected through the sensor group 5, so that people can monitor the underwater water quality of the river in real time.

[0037] However, when the equipment is used underwater in a river, the flow of water will drive sand and gravel to flow together, and the flowing sand and gravel will cause impact damage to the sensor, resulting in interference with underwater data collection and reducing the accuracy of underwater data collection; therefore, an isolation net 7 is provided, and the sensor group 5 on the mounting block 4 is located inside the isolation net 7, and the sand and gravel in the water flow are intercepted and isolated by the isolation net 7 to prevent the sand and gravel in the water from colliding with the sensor group 5 under the drive of the water flow, causing damage to the sensor group 5 and affecting the collection of underwater data; at the same time, in the process of isolating and intercepting sand and gravel, the sand and gravel will contact and collide with the isolation net 7 to generate vibration and noise, thereby interfering with the underwater hydrophone 104 to collect underwater vibration noise, and the underwater hydrophone 104 needs to be in direct contact with water during operation, therefore, when the underwater hydrophone 104 is working, by controlling the multi-stage electric push rod 102 The circular plate 103 and the underwater hydrophone 104 are driven to move upward in the hollow of the cylinder 101, so that the underwater hydrophone 104 pushes open the cover plate 03 through the connecting hole 02, and the underwater hydrophone 104 rises from the middle of the mounting top plate 1. By raising the underwater hydrophone 104 from the middle of the mounting top plate 1, the detection end of the underwater hydrophone 104 is kept away from the isolation net 7, so as to avoid the isolation net 7 from affecting the underwater vibration and noise collection of the underwater hydrophone 104. In addition, the cylinder 101 and the mounting block 4 are two independent parts. The cylinder 101 is connected to the mounting block 4 through a buffer water bag 105. During the operation of the underwater hydrophone 104, the buffer water bag 105 can buffer and absorb the vibration generated by the impact and collision of the water flow and the sand and gravel in the water flow on the isolation net 7, thereby reducing the influence of the equipment's own vibration on the underwater hydrophone 104, which is beneficial to improving the accuracy of the underwater hydrophone 104 in collecting and detecting underwater vibration and noise.

[0038] At the same time, it is taken into consideration that in the process of the isolation net 7 intercepting sand and gravel in the water flow, the intercepted sand and gravel will accumulate on the surface of the isolation net 7, blocking the isolation net 7, and thus affecting the monitoring of the external underwater water quality conditions by the sensor group 5. Therefore, when working, the electric slip ring 6 is controlled to drive the isolation net 7 to rotate clockwise from top to bottom. Through the rotation of the isolation net 7, the sand and gravel filtered and intercepted on the surface of the isolation net 7 can be transferred to the rear of the sensor group 5, that is, the sand and gravel intercepted on the surface of the isolation net 7 are transferred in the opposite direction of the water flow, and then driven by the water flow, the sand and gravel on the isolation net 7 that rotates to the rear of the sensor group 5 are taken away, so as to avoid the accumulation of sand and gravel on the surface of the isolation net 7, which affects the monitoring and collection effect of the sensor group 5.

[0039] In addition, blades 9 are provided on the surface of the isolation net 7. When the electric slip ring 6 drives the isolation net 7 to rotate, it also drives the blades 9 to rotate. The rotation of the blades 9 disturbs the flowing water. The blades 9 disturb the water flow toward the isolation net 7, so that part of the water flow flows away from the side of the isolation net 7, avoiding the water flow and the sand and gravel carried in the water flow from directly hitting the isolation net 7, thereby reducing the impact force of the water flow and the sand and gravel in the water flow on the isolation net 7, thereby reducing the external force on the entire equipment, so that the underwater hydrophone 104 can work more stably, which is further conducive to improving the accuracy of data collection; and when the water flow drives the water plants to flow to the surface of the isolation net 7, the blades 9 contact and intercept the water plants, so that part of the water plants are intercepted on the blades 9, thereby reducing the contact between the water plants and the isolation net 7, and reducing the risk of the water plants being tightly stuck on the surface of the isolation net 7, so that the intercepted water plants are easy to be carried away by the subsequent water flow.

[0040] At the same time, it is taken into consideration that the flow velocity of the river is easily affected by the external environment (such as water release from the upstream dam, heavy rainfall, etc.). When the flow velocity of the water increases, the water flow is easy to carry up the larger sand and gravel deposited on the riverbed, making it flow with the water flow, so that the equipment is also hit by larger sand and gravel when working underwater in the river. When the surface of the isolation net 7 is hit by larger sand and gravel, even if it is guided by the rotation of the isolation net 7 and the blades 9, there is still a large impact force directly acting on the isolation net 7, which will affect the accuracy of the underwater hydrophone 104 in collecting and detecting underwater vibration noise. Therefore, when larger sand and gravel hit the surface of the isolation net 7, the impacted part of the isolation net 7 is deformed toward the middle of the electric slip ring 6. , so that the rib rod 71 slides on the connecting block of the rotating part of the electric slip ring 6, and then the compression spring 8 contracts and deforms, and the impact force on the surface of the isolation net 7 is absorbed and buffered by the compression spring 8 through the contraction and deformation, thereby reducing the impact force of the larger sand and gravel from the outside, and cooperating with the buffering energy absorption of the buffer water bag 105, the accuracy of the data collection of the underwater hydrophone 104 is relatively guaranteed; it should be noted that the connection position of the electric slip ring 6 and the isolation net 7 is provided with an elastic cloth 10, and the connection position of the connecting block of the electric slip ring 6 and the isolation net 7 is shielded by the elastic cloth 10 to prevent sand and stones in the water from entering the isolation net 7 from between the two and causing damage to the internal sensor group 5, and to prevent sand and stones in the water from contacting the compression spring 8 and affecting its normal operation.

[0041] At the same time, during the operation of the underwater hydrophone 104, the underwater hydrophone 104 is in direct contact with the water flow. When the current meter installed on the top plate 1 detects that the river flow rate is too high, the water flow will drive more sand and gravel to flow. At this time, the underwater hydrophone 104 is prone to impact damage when it continues to work. Therefore, when it is detected that the river flow rate is too high, the multi-stage electric push rod 102 can be controlled to drive the circular plate 103 and the underwater hydrophone 104 to move downward again, so that the underwater hydrophone 104 can be moved down to the cylinder 101 for protection. Figure 4 As shown, the underwater hydrophone 104 is prevented from being easily damaged during continuous operation underwater, and a rubber gasket is provided on the outer ring surface of the circular plate 103, the circular plate 103 and the hollow part of the cylinder 101 are in a closed state, the rotating ring 10101 is sealed with the clamping rod 10301, and the rotating ring 10101 is sealed with the cylinder 101, so that the circular plate 103 and the rotating ring 10101 are in a sealed state, preventing external water from contacting the multi-stage electric push rod 102 and the power components of the underwater hydrophone 104, thereby ensuring the normal operation of the multi-stage electric push rod 102 and the underwater hydrophone 104.

[0042] As the underwater hydrophone 104 continues to work, its surface is prone to algae and other debris, and the algae and other debris attached to the surface will hinder the collection of noise, thereby reducing the accuracy of underwater vibration noise collection. Therefore, in the initial state, the underwater hydrophone 104 is located in the cylinder 101, and the clamping rod 10301 is docked and engaged with the clamping plate 601. Therefore, when the multi-stage electric push rod 102 drives the circular plate 103 and the underwater hydrophone 104 to reset downward and enter the cylinder 101, water enters the cylinder 101 through the connecting hole 02, and the clamping rod 10301 is docked and engaged with the clamping plate 601 of the electric slip ring 6 again, and then the electric slip ring 6 is controlled to drive the circular plate 103 and the underwater hydrophone 104 to rotate. When the underwater hydrophone 104 rotates, The bristles 106 on the cylinder 101 brush the surface of the underwater hydrophone 104, brushing off the algae and other impurities attached to its surface, thereby ensuring the accuracy of the subsequent data collection by the underwater hydrophone 104; and when the subsequent multi-stage electric push rod 102 continues to drive the circular plate 103 and the underwater hydrophone 104 to move upward for work, the bristles 106 scrape off the algae and other impurities on the underwater hydrophone 104, and through the upward movement of the circular plate 103, the water and algae impurities brushed in the hollow part of the cylinder 101 can also be driven upward, and at this time, the underwater hydrophone 104 extends out to the outside to work, and the cover plate 03 is in an open state. When the external water flows, it will enter the connecting hole 02, and then bring out the algae impurities above the circular plate 103 and take them away with the water flow.

[0043] Example 2

[0044] On the basis of Example 1, Figure 1 and Figure 5As shown, it also includes a multi-stage electric push rod 201 and a support rod 202; each mounting rod 2 is fixedly connected to a multi-stage electric push rod 201; each telescopic part of the multi-stage electric push rod 201 is fixedly connected to a support rod 202, and the support rod 202 is slidably connected to the inside of the mounting rod 2.

[0045] A pressure sensor is provided at the bottom of the support rod 202. When the whole device moves downward in the water, the support rod 202 contacts and senses the bottom of the river, thereby determining the distance between the device and the river bottom, making it easy to adjust the distance between the whole device and the river bottom.

[0046] On the basis of the above-mentioned embodiment 1, when the entire device is manually moved down into the river water through the connecting rod, the multi-stage electric push rod 201 is then controlled simultaneously to drive the support rod 202 to move, so that the support rod 202 moves out of the mounting rod 2, so that when the device moves underwater, it is sensed by the pressure sensor on the support rod 202, so as to determine the distance between the device and the river bottom, so as to facilitate the adjustment of the spacing between the entire device and the river bottom, and after determining the position of the device in the water, the multi-stage electric push rod 201 is continued to be controlled to drive the support rod 202 to move downward, so that the support rod 202 moves down and inserts into the river bottom to support the entire device, cooperate with the fixation of the connecting rod, and improve the stability of the device underwater.

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
