Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water resources survey, in particular, relates to a portable hydrology and water resources survey device. BACKGROUND

[0002] The hydrology and water resources survey device refers to a special instrument and system for systematically collecting, accurately monitoring, detailed recording and in-depth analyzing hydrological elements (such as water level, flow, flow rate, water temperature, sediment content, etc.) and water resources related parameters (such as water quality indicators, precipitation, evaporation, etc.), aiming to provide reliable data support and decision basis for rational development, efficient utilization, scientific management and flood control and disaster reduction of water resources.

[0003] At present, when using the survey device, the survey head is in a fixed position, and different water depths cannot be surveyed. When using the survey device, the survey head at the bottom of the floating plate is used to survey water resources. However, in the actual use process, since some polluted water bodies contain a large amount of blue-green algae and other pollutants, the outer cylindrical surface and the bottom side of the existing detection probe are easily adhered by pollutants after being inserted into the water body, thereby affecting normal detection. SUMMARY

[0004] In view of the problems in the related art, the application provides a portable hydrology and water resources survey device to overcome the above technical problems existing in the prior art.

[0005] To solve the above technical problems, the application is realized by the following technical scheme: The application is a portable hydrology and water resources survey device, which comprises a floating member serving as the buoyancy support base of the entire device to ensure stable floating of the device on the water surface. A disc is fixedly installed above the floating member, and the disc serves as the main support platform of the device and bears a plurality of key components.

[0006] A first motor is fixedly installed above the disc, and the first motor serves as a power source, and a threaded cylinder is fixedly installed at the output end of the first motor. The threaded cylinder is matched with a threaded rod in a threaded connection manner, and when the threaded cylinder rotates under the drive of the first motor, the threaded rod can move up and down. A survey head is fixedly installed at the end of the threaded rod away from the threaded cylinder, and the survey head is the core component of the device for hydrology and water resources survey and can obtain key hydrological data.

[0007] A connecting member is fixedly installed at the top of the survey head, and the connecting member is connected with the bottom of the floating member through an extension rod. The design of the extension rod enables the survey head to remain stable during up and down movement and also adapts to survey requirements of different depths. A first transmission wheel is also fixedly installed at the output end of the first motor, and the first transmission wheel is transmissionally connected with a second transmission wheel through a transmission belt, thereby realizing power transmission.

[0008] The inner part of the second transmission wheel is fixedly installed with a ratchet wheel, which is engaged with a pawl. The pawl is fixedly connected with a reciprocating threaded rod through a return spring. When the ratchet wheel rotates under the drive of the second transmission wheel, the pawl will reciprocate under the action of the ratchet wheel, thereby driving the reciprocating threaded rod to rotate. A cleaning ring is threadedly connected to the reciprocating threaded rod, and a brush is fixedly installed in the cleaning ring. The brush is in close contact with the survey head. Under the drive of the reciprocating threaded rod, the cleaning ring will reciprocate up and down, so as to clean the survey head with the brush, preventing the survey head from being affected by impurities or algae in water after long-term use.

[0009] Further, the threaded cylinder is rotatably installed on the floating member, ensuring the stability of the threaded cylinder during rotation. One end of the telescopic rod is fixedly installed on the connecting member, and the other end is fixedly installed on the bottom of the floating member, providing stable support and guidance for the up and down movement of the survey head.

[0010] Further, the first transmission wheel and the second transmission wheel are both rotatably installed on the disc, ensuring smooth operation of the transmission system. One end of the pawl is fixedly installed with a return spring, and the other end of the return spring is fixedly installed on the reciprocating threaded rod, so that the pawl can quickly reset after oscillation. The reciprocating threaded rod is rotatably installed on the floating member, providing power support for the up and down reciprocating movement of the cleaning ring.

[0011] Further, both ends of the pawl are provided with limit blocks for limiting, preventing the pawl from exceeding the safe range during oscillation. Both limit blocks are fixedly installed on the fixed disc, which is fixedly installed on the disc, providing a stable installation basis for the limit blocks. The end of the cleaning ring away from the reciprocating threaded rod is slidably connected with a guide rod, which is fixedly installed on the bottom of the floating member, ensuring the stability of the cleaning ring during up and down reciprocating movement.

[0012] Further, the brush is provided with a plurality of brushes, which are uniformly distributed on the inner side of the cleaning ring, ensuring comprehensive cleaning of the survey head. The plurality of brushes all have a deformation force, which can better fit the surface of the survey head, improving the cleaning effect. The ends of the reciprocating threaded rod and the guide rod away from the floating member are both fixedly installed with a limit assembly, preventing the cleaning ring from falling off during movement.

[0013] Further, a first gear is fixedly installed above the floating member, and a second gear is engaged with the first gear. The output end of a second motor is fixedly installed with the second gear. The second motor drives the second gear to rotate, thereby driving the first gear to rotate. The second motor is fixedly installed on the disc, providing stable power support for the entire drive system.

[0014] Further, the first gear is provided with a connecting rod at both ends, and the two connecting rods are fixedly installed with driving frames as the installation basis of the driving blades. The driving blades are rotatably installed in the two driving frames, and can generate thrust during rotation to push the device to move on the water surface. The driving blades are fixedly installed with the output ends of waterproof motors, and the waterproof motors can normally work in water to provide power for the driving blades. The two waterproof motors are fixedly installed on the driving frames to ensure the stable operation of the waterproof motors.

[0015] Further, the first gear is provided with a protective cover fixedly installed on the disc, which can protect the transmission components such as the first gear and the second gear from being impacted and corroded by water-borne debris. The protective cover is fixedly installed with survey equipment on the top, which is the core component for data processing and storage of the device. A plurality of solar panels are fixedly installed on the outer surface of the survey equipment, which can convert solar energy into electric energy to provide part of the power support for the device. A signal transmitter and a warning light are fixedly installed on the top of the survey equipment, the signal transmitter can transmit the surveyed data to the remote monitoring center in real time, and the warning light can send a warning signal when the device is abnormal or needs to be reminded.

[0016] The present application has the following advantages: 1. The portable hydrological and water resource surveying device has the function of automatically cleaning the surveying head. During the surveying process, when dirt adheres to the surface of the surveying head and affects the accuracy of the surveying data, the first motor is started in reverse rotation, and the linkage mechanism of the first transmission wheel, the transmission belt, the second transmission wheel, the ratchet wheel, the pawl and the return spring is used to drive the reciprocating threaded rod to rotate, so that the cleaning ring which is threadedly connected with the reciprocating threaded rod and limited by the guide rod makes reciprocating linear motion. The brushes uniformly distributed on the inner side of the cleaning ring and having deformation force can closely adhere to the surface of the surveying head, effectively removing dirt. This design avoids the inconvenience and potential risks of manual cleaning, ensures that the surveying head is always clean, and thus guarantees the accuracy and reliability of the hydrological and water resource surveying data.

[0017] 2. The device is equipped with a flexible moving and steering system. The waterproof motor fixed on the driving frame is started to drive the driving blades to rotate, providing power for the device to move in water. At the same time, the second motor is started to drive the first gear to rotate through the meshing transmission of the second gear and the first gear, thereby changing the direction of the driving frame and the driving blade connected thereto, realizing flexible adjustment of the moving direction of the device. This design enables the device to freely move and steer in different water environments according to actual surveying needs, improves the efficiency and adaptability of the surveying, and can more comprehensively cover the surveying area.

[0018] 3、The device adopts a solar power supply mode, a plurality of solar panels fixed on the outer surface of the surveying equipment can absorb solar energy and convert it into electric energy to provide part of the energy for the device, thereby reducing the dependence on external power supply, reducing the use cost, and being more environmentally friendly. In addition, the signal transmitter fixed above the surveying equipment can transmit the data collected by the surveying equipment to the external equipment in real time, so that the staff can obtain and analyze the data in time. When the device has an abnormal condition, the warning light can send a warning signal to remind the staff to handle it in time, further improving the convenience and safety of the device.

[0019] Of course, implementing any product of the present application does not necessarily require all the advantages described above. BRIEF DESCRIPTION OF DRAWINGS

[0037] In one embodiment, a protective cover 29 is provided above the first gear 22, and the protective cover 29 is fixedly mounted on the disk 2, providing protection for the components above it. A surveying device 30 is fixedly mounted above the protective cover 29, and the surveying device 30 is used for comprehensive hydrological and water resource surveys and data collection. Several solar panels 31 are fixedly mounted on the outer surface of the surveying device 30, providing some of the energy to the device. A signal transmitter 32 and a warning light 33 are fixedly mounted above the surveying device 30. The signal transmitter 32 is used to transmit survey data to external devices, and the warning light 33 emits a warning signal when the device malfunctions.

[0038] The working principle of the convenient hydrological and water resources survey device proposed in this invention is as follows: when the device is in working condition, if it needs to move on the water surface, the two waterproof motors 28 fixedly installed on the drive frame 26 are started. The output end of the waterproof motor 28 drives the drive blades 27 installed in the drive frame 26 to rotate. Since the two drive frames 26 are fixed at both ends of the first gear 22 through the connecting rod 25, the power generated by the rotation of the drive blades 27 propels the device to move in the water.

[0039] To change the direction of movement of the device or adjust the movement of some parts of the device, the second motor 24, which is fixedly mounted on the disc 2, is started. The output end of the second motor 24 drives the fixedly connected second gear 23 to rotate. The second gear 23 meshes with the first gear 22, which is fixedly mounted above the floating part 1, thereby driving the first gear 22 to rotate. The rotation of the first gear 22 can change the direction of the drive frame 26 and drive blade 27 connected to it, thereby adjusting the direction of movement of the device.

[0040] When conducting hydrological and water resource surveys, the surveying equipment 30, fixedly installed above the disc 2, begins operation to perform comprehensive surveys and data collection on hydrological and water resources. Simultaneously, several solar panels 31 fixed to the outer surface of the surveying equipment 30 absorb solar energy and convert it into electrical energy, providing a portion of the power for the device.

[0041] During the survey, if the first motor 3 drives the threaded cylinder 4 to rotate, and the threaded rod 5 drives the survey head 6 to move for surveying, if it is necessary to clean the dirt on the surface of the survey head 6, under specific conditions such as the first motor 3 reversing, the first transmission wheel 9, transmission belt 10, second transmission wheel 11, ratchet 12, pawl 13, and return spring 14 drive the reciprocating threaded rod 15, which is rotatably mounted on the floating part 1, to rotate. This causes the cleaning ring 16, which is threadedly connected to the reciprocating threaded rod 15 and slidably connected to the guide rod 20 (the guide rod 20 is fixed to the bottom of the floating part 1), to reciprocate. The brushes 17, which are evenly distributed on the inner side of the cleaning ring 16 and have deformation force, clean the surface of the survey head 6.

[0042] A protective cover 29, fixed above the first gear 22 and mounted on the disk 2, provides protection for components such as the first gear 22 and the second gear 23. A signal transmitter 32, fixedly mounted above the surveying equipment 30, transmits the surveying data collected by the surveying equipment 30 to external devices; when an abnormality occurs in the device, a warning light 33 emits a warning signal.
