Description

Technical Field

[0001] The invention belongs to the field of hydrological measurement devices, and in particular relates to a hydrological and water resources engineering observation device. Background Art

[0002] Hydrological monitoring includes: using water level sensors to monitor water level height; using flow sensors to monitor water flow; using water quality sensors to monitor water quality parameters; and using meteorological sensors to monitor meteorological parameters related to hydrology.

[0003] For meteorological sensors (temperature sensors, air pressure sensors, wind speed sensors, etc.), when they monitor meteorological parameters at the seaside, they are severely eroded by sea breeze and waves, which greatly reduces the service life of the above meteorological sensors. Therefore, it is necessary to design a hydrological and water resources engineering observation device that can store and protect meteorological sensors during non-monitoring periods to extend the service life of meteorological sensors. Summary of the invention

[0004] A hydrology and water resources engineering observation device of the present invention can store and protect meteorological sensors.

[0005] A hydrological and water resources engineering observation device of the present invention comprises a mounting plate, a support rod is fixed to the upper surface of the mounting plate, a support plate is fixed to the upper end of the support rod; an equipment plate is arranged above the support plate, and a storage device is arranged on the lower surface of the equipment plate; The storage device includes: The storage bucket is fixed on the lower surface of the equipment plate, the support plate is sleeved on the storage bucket, and the support plate is fixedly connected to the storage bucket; the upper end of the storage bucket is open; The lifting plate is in the storage barrel, and is movably mounted on the inner wall of the storage barrel, and can move vertically. A meteorological sensor is fixed on the upper surface of the lifting plate; A threaded rod, threadedly connected to the lifting plate; An opening and closing hole is provided on the equipment plate, and an opening and closing device for opening and closing the opening and closing hole is provided at the opening and closing hole; after the opening and closing device opens the opening and closing hole, the lifting plate rises to extend the meteorological sensor out of the opening and closing hole; It also includes a driving device, which is used to raise and lower the lifting plate and open and close the opening and closing device.

[0006] Furthermore, the driving device comprises: A driving shaft is rotatably connected to the storage barrel, and one end of the driving shaft passes through the storage barrel; The driving disc is fixed to one end of the driving shaft in the storage barrel and is located below the lifting plate; the driving disc is a circular disc, and the axis of the driving disc coincides with the axis of the driving shaft; a tooth segment A is integrally provided on the circumferential side wall of the driving disc, and the tooth segment A covers one section of the circumferential side wall of the driving disc, and the area of ​​the circumferential side wall of the driving disc not including the tooth segment A is set as an idle area A; A driving gear, fixed on the threaded rod, capable of meshing with tooth segment A; The linkage disk is fixed at one end of the drive shaft passing through the storage barrel. The linkage disk is a circular disk, and the axis of the linkage disk coincides with the axis of the drive shaft. A tooth segment B is integrally provided on the circumferential side wall of the linkage disk, and the tooth segment B covers one section of the circumferential side wall of the linkage disk. The area of ​​the circumferential side wall of the linkage disk not including the tooth segment B is set as an idle area B. The linkage shaft is rotatably connected to the equipment plate, and its axis is parallel to the driving disc; The linkage gear is fixed on the linkage shaft and can mesh with the tooth segment B. When the linkage gear meshes with the tooth segment B, the tooth segment A does not mesh with the driving gear. When the tooth segment A meshes with the driving gear, the linkage gear does not mesh with the tooth segment B. A first motor for rotating the drive shaft is also included.

[0007] Only one first motor is needed to drive the opening and closing device and the lifting plate. The tooth segments A and B are used to mesh with the driving gear and the linkage gear in a time-sharing manner. When the opening and closing device is opened, although the tooth segment A rotates, the tooth segment A does not transmit power to the driving gear, resulting in the lifting plate not rising when the opening and closing device is opened. On the contrary, after the opening and closing device is opened, the tooth segment B is disengaged from the linkage gear, and only the tooth segment A is meshed with the driving gear, and the rising of the lifting plate will not affect the opening and closing device. This solution cleverly achieves the purpose of pushing the meteorological sensor out of the opening and closing hole when working by driving the driving gear and the linkage gear part-time by the tooth segments A and B. When stored, the actions are opposite, and the closing of the opening and closing device and the descent of the lifting plate do not affect each other.

[0008] Furthermore, the opening and closing device comprises: The gear ring is rotatably connected to the equipment plate and is in a circular ring shape; teeth are arranged on the circumferential outer wall of the gear ring; the axis of the gear ring is parallel to the axis of the linkage shaft; The control gear is fixed on the linkage shaft and can mesh with the teeth on the outer wall of the gear ring; A plurality of linkage components; arranged in a circular array along the axis of the gear ring; The linkage components include: A connecting rod, one end of which is rotatably connected to the gear ring through shaft A; The closing plate is connected to the inner wall of the cavity by rotation via axis B, and the other end of the connecting rod is connected to the closing plate by rotation via axis C; the closing plates of all linkage components can close the opening and closing holes after contacting each other; the axes of axis A, axis B and axis C are all parallel to the axis of the linkage shaft.

[0009] A structure in which multiple closing plates rotate to close the opening and closing holes is adopted, rather than the closing plates moving horizontally to close the opening and closing holes. Because the multiple closing plates rotate to close the opening and closing holes faster, the opening and closing holes can be opened quickly, and only a small number of teeth on the tooth segment B are needed to complete the action. As for the design, because the tooth segments A and B are required to mesh with the driving gear and the linkage gear at a time-sharing basis, the tooth segments A and B cannot occupy larger circumferential areas of the driving disk and the linkage disk respectively. The rotating closing plate saves the amount of teeth on the tooth segment B and meets the design requirements.

[0010] Furthermore, a connecting column is fixedly connected to the lower surface of the mounting plate, and a base plate is fixed to the lower end of the connecting column; a protective component is provided on the mounting plate, and the protective component includes: The collar is sleeved on the mounting plate, the axis of the collar is arranged vertically, the collar is rotatably connected to the mounting plate, and a gear ring is arranged on the inner wall of the collar; The protective plate is fixed on the collar; when viewed from above, the shape of the protective plate is a semicircular arc. A second motor has a protection gear fixed on its rotating shaft, the protection gear meshing with the collar; The control module can receive data from the meteorological sensor and control the actions of the first motor and the second motor.

[0011] The design of the protective component can resist the impact of waves and protect the connecting column. After monitoring the data of the meteorological sensor, the control module can obtain the wind direction according to the wind direction sensor, and adjust the angle of the protective plate so that the outer wall of the protective plate faces the wind direction. The waves blown by the wind hit the protective plate, which can reduce the impact on the connecting column. All components of this solution are made of corrosion-resistant materials, such as plastic. The protective plate is not designed to be a ring and surround the connecting column, mainly because the display screen needs to be installed later. The surrounding protective plate will not be able to install the display screen.

[0012] Furthermore, a display screen is installed on the inner wall of the protective plate, and the display screen is electrically connected to the control module.

[0013] The display screen can display the corresponding meteorological data according to the signal of the control module for nearby people to know. The display screen is set on the inner wall of the protective plate to reduce the impact of waves on it.

[0014] Furthermore, an equipment rack is fixedly connected to the upper surface of the equipment board, a camera is installed on the equipment rack, and the camera is electrically connected to the control module.

[0015] The camera can be used to capture images of the rising and falling waves for subsequent analysis of the hydrological information of the waves. Beneficial Effects

[0016] This device mainly utilizes tooth segment A and tooth segment B, so that the first motor can drive the opening and closing device and the lifting plate in time-sharing, so that the opening and closing of the opening and closing device and the lifting and lowering of the lifting plate do not interfere with each other, and are controlled by the first motor at the same time. The meteorological sensor on the lifting plate can extend out of the opening and closing hole, and the meteorological data related to hydrology can be collected. It can avoid the situation where the meteorological sensor is outside the opening and closing hole all the time and is eroded by the sea breeze, thereby extending the life of the meteorological sensor.

[0032] The linkage shaft 19 has an axis arranged vertically, an upper end of which is rotatably connected to the equipment plate 5 , and a lower end of which is rotatably connected to the mounting plate 32 .

[0033] The linkage gear 20 is fixed on the linkage shaft 19 and coincides with the axis of the linkage shaft 19. When the tooth segment B18 is located at the linkage gear 20, the tooth segment B18 is meshed with the linkage gear 20; when the idle area B is located at the linkage gear 20, the tooth segment B18 is no longer meshed with the linkage gear 20.

In the present embodiment, the opening and closing hole 21 is in the shape of a circular hole, and the axis of the opening and closing hole 21 coincides with the axis of the storage barrel 6. The meteorological sensor 22 on the lifting plate 7 can pass through the opening at the top of the storage barrel 6 through the opening of the opening 21 as the lifting plate 7 rises.

[0035] See Figure 4 and Figure 5 A cavity is provided inside the equipment plate 5, and an opening and closing device for opening and closing the opening and closing hole 21 is provided in the cavity. The opening and closing device includes: The gear ring 23 is annular and rotatably connected in the cavity. The surface of the gear ring 23 is provided with a groove and a rod for limiting the gear ring 23 to rotate only. The axis of the gear coincides with the axis of the opening and closing hole 21. The diameter of the middle opening of the gear ring 23 is larger than the diameter of the opening and closing hole 21, ensuring that the gear ring 23 does not affect the meteorological sensor 22 from extending out of the opening and closing hole 21. The circumferential side wall of the gear ring 23 is provided with teeth.

[0036] The control gear 24 is fixed to the upper end of the linkage shaft 19 . The control gear 24 is in the cavity, and its axis coincides with the linkage shaft 19 . The control gear 24 meshes with the teeth on the circumferential outer wall of the gear ring 23 .

When the gear ring 23 rotates, the gear ring 23 drives the closing plate 26 to rotate around the shaft B34 through the connecting rod 25, and all the closing plates 26 can close the opening and closing hole 21 after contacting each other. When all the closing plates 26 are separated from each other, the opening and closing hole 21 is open, and the aforementioned meteorological sensor 22 can pass through the opening and closing hole 21.

[0038] An equipment frame 27 is fixedly connected to the upper surface of the equipment plate 5. In this embodiment, the equipment frame 27 is in an inverted "L" shape. A camera 28 is fixedly installed on the equipment frame 27 to capture images of the water area.

[0039] See Figure 5 , and also includes a protective component for reducing the impact of waves on the connecting column of the device, the protective component includes: The collar 29, in this embodiment, is in the shape of a circular ring, and the axis of the collar 29 coincides with the axis of the mounting plate 32. The collar 29 is rotatably connected to the mounting plate 32, the upper end surface of the collar 29 is higher than the upper surface of the mounting plate 32, and the inner wall of the collar 29 is integrally provided with a gear ring, the axis of the gear ring coincides with the axis of the collar 29, and the gear ring is located above the mounting plate 32.

[0040] The second motor (not shown) is wrapped by a protective shell, and the non-rotating shaft end is fixed to the lower surface of the mounting plate 32. The rotating shaft of the second motor is arranged vertically, and the rotating shaft of the second motor passes through the mounting plate 32. The mounting plate 32 is provided with a through hole for the rotating shaft of the second motor to pass through. A protective gear 30 is fixedly connected to the rotating shaft of the second motor, and the axis of the protective gear 30 coincides with the axis of the rotating shaft of the second motor, and the protective gear 30 is meshed with the ring gear.

[0041] The protective plate 31, in this embodiment, is in the shape of a semicircular arc in a top view, and the protective plate 31 is fixed on the circumferential outer wall of the collar 29. A display screen can be installed on the inner wall of the protective plate 31, which can display the data monitored by the meteorological sensor.

[0042] It also includes a control module, which is fixedly installed on the inner bottom wall of the storage barrel 6 and is electrically connected to the meteorological sensor 22, the first motor 15, the second motor 30, the camera 28 and the display screen through wires. It can receive data from the meteorological sensor 22 and display it on the display screen. It can also control the operation of the first motor 15 and the second motor 30 by a remote terminal signal and transmit the monitored meteorological sensor 22.

[0043] How to use this device The device is installed on the coast; the base plate 1 is fixedly connected to the coast by bolts. The camera 28 can capture images of waves on the sea, and send them to the terminal through the wireless transmission module carried by the control module, and the terminal analyzes the hydrological data captured by the camera 28.

[0044] If the terminal needs to collect weather data at the location of the device, the weather sensor 22 needs to be extended from the top of the storage barrel 6 to the opening and closing hole 21. The specific operation is as follows: First, the terminal sends a signal for monitoring meteorological data to the control module through the wireless transmission module. After receiving the signal, the control module controls the actions of related components. The control module rotates the first motor 15, and the first motor 15 rotates the drive shaft 10 through the active bevel gear 16 and the driven bevel gear 14. Since the drive disk 11 and the linkage disk 17 are fixedly connected to the drive shaft 10, the drive shaft 10, the drive disk 11 and the linkage disk 17 rotate around the axis of the drive shaft 10 as a whole.

[0045] Assume the initial time is Figure 3 In this state, the tooth segment B18 on the linkage disk 17 is meshed with the linkage gear 20, and the tooth segment A12 on the drive disk 11 is not meshed with the drive gear 13. Therefore, the above-mentioned whole only drives the linkage gear 20 to rotate.

[0046] After the linkage gear 20 rotates, since the linkage shaft 19 and the control gear 24 are fixedly connected to the linkage gear 20 , the linkage shaft 19 , the linkage gear 20 and the control gear 24 rotate around the axis of the linkage shaft 19 as a whole.

[0047] Because the toothed ring 23 of the opening and closing device is meshed with the control gear 24, the opening and closing device is activated, and all the closing plates 26 are separated from each other to open the opening and closing hole 21. Since the toothed segment A12 on the driving disk 11 is not meshed with the driving gear 13, the meteorological sensor 22 is still in the storage barrel 6 and does not rise.

[0048] As the first motor continues to rotate, the tooth segment B18 on the linkage disk 17 disengages from the linkage gear 20, and the linkage gear 20 is located in the idle area B. The linkage disk 17 no longer drives the opening and closing device to move, and all the closing plates 26 remain separated from each other, and the opening and closing holes 21 remain open. After the tooth segment B18 on the linkage disk 17 disengages from the linkage gear 20, the tooth segment A12 on the drive disk 11 meshes with the drive gear 13, and the drive gear 13 and the threaded rod 8 rotate as a whole. Since the lifting plate 7 is threadedly connected to the threaded rod 8, and the lifting plate 7 can only be lifted, the lifting plate 7 rises under the action of the threaded rod 8, and the lifting plate 7 is connected to the meteorological sensor 22 and extends from the opening and closing hole 21. The meteorological data monitored by each sensor in the meteorological sensor 22 is transmitted to the control module. If the wind direction at this time is measured to be A, the control module controls the second motor to move, and according to the wind direction A and the position of the protective plate 31 at this time, the rotation angle of the second motor is reversely solved, and then the control module controls the second motor to rotate, and the outer wall of the protective plate 31 faces the wind direction A, which can protect the display screen, and the control module displays the meteorological data and the image taken by the camera on the display screen. When the meteorological sensor 22 is retracted into the storage barrel 6, the first motor is reversed, and the process is opposite to the above, which will not be repeated.

[0049] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
