Description

Technical Field

[0001] This invention belongs to the field of hydrological measurement devices, specifically relating to a hydrological and water resources engineering observation device. Background Technology

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

[0003] For meteorological sensors (such as temperature sensors, barometric pressure sensors, and wind speed sensors), when monitoring meteorological parameters at the seaside, they are severely corroded by sea winds and waves, greatly reducing their lifespan. Therefore, it is necessary to design a hydrological and water resources engineering observation device that can store and protect the meteorological sensors during non-monitoring periods, thereby extending their service life. Summary of the Invention

[0004] The present invention provides a hydrological and water resources engineering observation device that can store and protect meteorological sensors.

[0005] The present invention provides a hydrological and water resources engineering observation device, including an installation plate, a support rod fixed on the upper surface of the installation plate, and a support plate fixed at the upper end of the support rod; an equipment plate is provided above the support plate, and a storage device is provided on the lower surface of the equipment plate.

[0006] Storage devices include:

[0007] The storage bin is fixed to the lower surface of the equipment plate, and the support plate is sleeved on the storage bin and fixedly connected to the storage bin; the upper end of the storage bin is open.

[0008] The lifting plate is located in the storage bucket and is movably locked onto the inner wall of the storage bucket. It can move vertically, and a weather sensor is fixed on the upper surface of the lifting plate.

[0009] The threaded rod is threadedly connected to the lifting plate.

[0010] The equipment plate has an opening and closing hole, and an opening and closing device is provided at the opening and closing hole for opening and closing the opening and closing hole; after the opening and closing device opens the opening and closing hole, the lifting plate rises and can extend the meteorological sensor out of the opening and closing hole.

[0011] It also includes a drive unit for raising and lowering the lifting plate and for opening and closing the opening and closing device.

[0012] Furthermore, the driving device includes:

[0013] A drive shaft is rotatably connected to the storage bucket, with one end of the drive shaft extending out of the storage bucket.

[0014] The drive disc is fixed at one end of the drive shaft, which is located below the lifting plate. The drive disc is a disc, and the axis of the drive disc coincides with the axis of the drive shaft. A toothed segment A is integrally provided on the circumferential side wall of the drive disc. The toothed segment A covers one section of the circumferential side wall of the drive disc. The area of ​​the circumferential side wall of the drive disc that is not toothed segment A is called the free area A.

[0015] The drive gear is fixed on the threaded rod and can mesh with tooth segment A;

[0016] The linkage plate is fixed at one end of the drive shaft that protrudes from the storage bin. The linkage plate is a disc, and the axis of the linkage plate coincides with the axis of the drive shaft. A toothed segment B is integrally provided on the circumferential side wall of the linkage plate. The toothed segment B covers one section of the circumferential side wall of the linkage plate. The area of ​​the circumferential side wall of the linkage plate that is not the toothed segment B is called the free area B.

[0017] The linkage shaft is rotatably connected to the equipment plate, and its axis is parallel to the drive disc.

[0018] The linkage gear is fixed on the linkage shaft and can mesh with tooth segment B; when the linkage gear meshes with tooth segment B, tooth segment A does not mesh with the drive gear; when tooth segment A meshes with the drive gear, the linkage gear does not mesh with tooth segment B.

[0019] It also includes a first motor for rotating the drive shaft.

[0020] A single motor can drive both the opening / closing device and the lifting plate. Using tooth segments A and B, which engage with the drive gear and linkage gear respectively on a time-sharing basis, when the opening / closing device is open, although tooth segment A rotates, it does not transmit power to the drive gear, causing the lifting plate not to rise. Conversely, when the opening / closing device is open, tooth segment B disengages from the linkage gear, leaving only tooth segment A engaged with the drive gear, ensuring the lifting plate's ascent does not affect the opening / closing device. This design cleverly achieves the purpose of pushing the weather sensor out of the opening / closing hole during operation by using tooth segments A and B to partially drive the drive gear and linkage gear. During retraction, the actions are reversed, and the closing of the opening / closing device and the descent of the lifting plate do not affect each other.

[0021] Furthermore, the opening and closing device includes:

[0022] The gear ring is rotatably connected to the equipment plate and is circular in shape; teeth are provided on the outer circumference of the gear ring; the axis of the gear ring is parallel to the axis of the linkage shaft.

[0023] The control gear is fixed on the linkage shaft and can mesh with the teeth on the outer circumference of the gear ring.

[0024] Multiple linkage components; arranged in a circumferential array along the axis of the toothed ring;

[0025] The linkage components include:

[0026] The connecting rod is rotatably connected to the gear ring at one end via shaft A;

[0027] The closing plate is rotatably connected to the inner wall of the cavity via shaft B, and the other end of the connecting rod is rotatably connected to the closing plate via shaft C; the closing plates of all linkage components can seal the opening and closing holes after contacting each other; the axes of shafts A, B and C are all parallel to the axis of the linkage shaft.

[0028] The design employs a structure where multiple rotating closing plates close the opening and closing holes, rather than using horizontally moving closing plates. This is because the rotation of multiple closing plates to close the opening and closing holes is faster and allows for quick opening of the holes. Only a small number of teeth in tooth segment B are needed to complete the action. In terms of design, since tooth segments A and B need to mesh with the drive gear and linkage gear at different times, tooth segments A and B cannot occupy large circumferential areas of the drive plate and linkage plate respectively. The rotating closing plates effectively save the number of teeth in tooth segment B, thus meeting the design requirements.

[0029] Furthermore, a connecting post is fixedly connected to the lower surface of the mounting plate, and a base plate is fixed to the lower end of the connecting post; a protective assembly is provided on the mounting plate, the protective assembly including:

[0030] A collar is fitted onto a mounting plate. The axis of the collar is set vertically. The collar is rotatably connected to the mounting plate. A toothed ring is provided on the inner wall of the collar.

[0031] The protective plate is fixed to the collar; viewed from the top view, the protective plate is semi-circular in shape.

[0032] The second motor has a protective gear fixed on its shaft, which meshes with a collar.

[0033] The control module can receive data from the weather sensor and control the operation of the first and second motors.

[0034] The protective components are designed to withstand wave impact and protect the connecting column. After monitoring data from weather sensors, the control module can determine the wind direction using a wind direction sensor and adjust the angle of the protective plate so that its outer wall faces the wind. This reduces the impact of waves hitting the connecting column. All components in this solution are made of corrosion-resistant materials, such as plastic. The protective plate is not designed as a ring encircling the connecting column primarily because a display screen will need to be installed later; an enclosed protective plate would prevent the installation of the display screen.

[0035] 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.

[0036] The display screen can show corresponding meteorological data based on signals from the control module, making it available to nearby people. Installing the display screen on the inner wall of the protective panel reduces the impact of waves.

[0037] Furthermore, a device frame is fixedly connected to the upper surface of the device board, and a camera is installed on the device frame. The camera is electrically connected to the control module.

[0038] It can capture images of ocean waves using a camera, which can then be used for subsequent hydrological analysis of the waves. Beneficial effects

[0039] This device primarily utilizes toothed segments A and B, enabling the first motor to drive the opening and closing device and the lifting plate in a time-sharing manner. This ensures that the opening and closing of the device and the raising and lowering of the plate do not interfere with each other, while simultaneously being controlled by the first motor. It allows the meteorological sensor on the lifting plate to extend beyond the opening and closing hole, enabling the collection of hydrological and meteorological data. This avoids the meteorological sensor being constantly exposed to sea breezes and extends its lifespan, preventing corrosion. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions 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, 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.

[0047] See Figure 1 A hydrological and water resources engineering observation device includes a base plate 1, with at least one connecting column 2 fixedly connected to the upper surface of the base plate 1. The connecting column 2 is vertically arranged. The upper end of each connecting column 2 is fixedly connected to a mounting plate 32. In this embodiment, the mounting plate 32 is disc-shaped and its axis is vertically arranged.

[0048] Multiple support rods 3 are fixed to the upper surface of the mounting plate 32, and the multiple support rods 3 are arranged vertically. The upper ends of the multiple support rods 3 are all fixedly connected to a support plate 4. An equipment plate 5 is provided above the support plate 4.

[0049] See Figure 1 , Figure 2 and Figure 3 This device also includes a storage device, which includes:

[0050] The storage bucket 6, in this embodiment, is a cylindrical container with its axis coinciding with the axis of the mounting plate 32; the upper end of the storage bucket 6 is open. The storage bucket 6 is fixed to the lower surface of the equipment plate 5. The support plate 4 is sleeved on the storage bucket 6, and the support plate 4 is fixedly connected to the storage bucket 6. Thus, the support plate 4, the equipment plate 5, and the storage bucket 6 are connected as a whole.

[0051] The lifting plate 7 is located inside the storage bin 6 and is movably mounted on the inner wall of the storage bin 6, allowing it to move along the axis of the storage bin 6. A weather sensor 22 is fixedly connected to the upper surface of the lifting plate 7 via a mounting bracket. Here, the weather sensor 22 does not refer to a single sensor, but rather to a sensor that integrates multiple sensors such as wind direction sensor, wind speed sensor, humidity sensor, and temperature sensor.

[0052] The threaded rod 8 has its axis set vertically, and the non-threaded part of the lower end of the threaded rod 8 is rotatably connected to the bottom wall of the storage bucket 6; the threaded rod 8 passes through the lifting plate 7, and the threaded rod 8 is threadedly connected to the lifting plate 7.

[0053] The guide rod 9 is set vertically along its axis. The lower end of the guide rod 9 is fixed to the bottom wall of the storage bucket 6. The guide rod 9 passes through the lifting plate 7. The lifting plate 7 has a hole for the guide rod 9 to pass through. When the lifting plate 7 moves along its axis, the lifting plate 7 also moves along the axis of the guide rod 9.

[0054] A drive unit is used to drive the threaded rod 8 to rotate, thereby enabling the lifting plate 7 to rise and fall. The drive unit includes:

[0055] The drive shaft 10, with its axis set vertically, is rotatably connected to the bottom wall of the storage bucket 6; the axis of the drive shaft 10 coincides with the axis of the storage bucket 6. The lower end of the drive shaft 10 extends out of the storage bucket 6.

[0056] The drive disc 11 is fixedly connected to the upper end of the drive shaft 10. The axis of the drive disc 11 coincides with the axis of the drive shaft 10. The drive disc 11 is disc-shaped and is located below the lifting plate 7. See Figure 2 A toothed segment is integrally provided on the circumferential sidewall of the drive disk 11. Let the toothed segment be toothed segment A12. Toothed segment A12 does not cover the entire circumferential sidewall of the drive disk 11, but only covers one part of the circumferential sidewall of the drive disk 11. Let the area of ​​the circumferential sidewall of the drive disk 11 that is not toothed segment A12 be the free area A.

[0057] The drive gear 13 is fixed to the non-threaded section of the threaded rod 8 and coincides with the axis of the threaded rod 8. When tooth segment A12 is located at the position of drive gear 13, tooth segment A12 meshes with drive gear 13; when the idle area A is located at the position of drive gear 13, tooth segment A12 no longer meshes with drive gear 13. Figure 3 This means that tooth segment A12 does not mesh with drive gear 13. In other words, drive disc 11 is not always meshed with drive gear 13.

[0058] Driven bevel gear 14 is fixed on drive shaft 10, and the axis of driven bevel gear 14 coincides with the axis of drive shaft 10.

[0059] The first motor 15, with its non-rotating shaft end fixed to the inner bottom wall of the storage bucket 6;

[0060] The driving bevel gear 16 is fixed on the rotating shaft of the first motor 15. The axis of the driving bevel gear 16 coincides with the axis of the rotating shaft of the first motor 15, and the driving bevel gear 16 meshes with the driven bevel gear 14.

[0061] Linkage disc 17 is disc-shaped, and its axis coincides with the axis of drive shaft 10. Linkage disc 17 is fixed to the lower end of drive shaft 10 and is located outside storage container 6. (See attached image) Figure 1 A toothed segment is integrally formed on the circumferential sidewall of the linkage disk 17, which is designated as toothed segment B18. Toothed segment B18 does not cover the entire circumferential sidewall of the linkage disk 17, but only covers a portion of the circumferential sidewall of the linkage disk 17. The area of ​​the circumferential sidewall of the linkage disk 17 that is not covered by toothed segment B18 is designated as the idle area B.

[0062] The linkage shaft 19 is vertically set, with its upper end rotatably connected to the equipment plate 5 and its lower end rotatably connected to the mounting plate 32.

[0063] The linkage gear 20 is fixed on the linkage shaft 19 and coincides with the axis of the linkage shaft 19. When tooth segment B18 is in the position of linkage gear 20, tooth segment B18 meshes with linkage gear 20; when idle area B is in the position of linkage gear 20, tooth segment B18 no longer meshes with linkage gear 20. Specifically: when tooth segment A12 meshes with drive gear 13, idle area B is in the position of linkage gear 20; when tooth segment B18 meshes with linkage gear 20, idle area A is in the position of drive gear 13.

[0064] The device plate 5 has an opening and closing hole 21 inside. In this embodiment, the opening and closing hole 21 is a round hole. The axis of the opening and closing hole 21 coincides with the axis of the storage bucket 6. The weather sensor 22 on the lifting plate 7 can pass through the opening and closing hole 21 from the opening at the top of the storage bucket 6 as the lifting plate 7 is raised.

[0065] See Figure 4 and Figure 5 The equipment plate 5 has a cavity inside, and the cavity is equipped with an opening and closing device for opening and closing the opening and closing hole 21. The opening and closing device includes:

[0066] A gear ring 23, in the form of a ring, is rotatably connected in the cavity. The surface of the gear ring 23 has grooves and rods to restrict its rotation. The axis of the gear coincides with the axis of the opening / closing hole 21. The diameter of the central opening of the gear ring 23 is larger than the diameter of the opening / closing hole 21, ensuring that the gear ring 23 does not interfere with the weather sensor 22 extending out of the opening / closing hole 21. Teeth are provided on the circumferential sidewalls of the gear ring 23.

[0067] The control gear 24 is fixed at 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 outer circumference of the gear ring 23.

[0068] Multiple linkage components are arranged in a circumferential array along the axis of the gear ring 23. The linkage components include:

[0069] One end of the connecting rod 25 is rotatably connected to the upper surface of the gear ring 23 via a shaft A33, the axis of which is set vertically;

[0070] The closing plate 26 is rotatably connected to the inner wall of the cavity via shaft B34, the axis of shaft B34 being vertically oriented; the other end of the connecting rod 25 is rotatably connected to the closing plate 26 via shaft C35. When the gear ring 23 rotates, the gear ring 23 drives the closing plate 26 to rotate around shaft B34 via the connecting rod 25. When all the closing plates 26 come into contact with each other, they can close the opening and closing hole 21. When all the closing plates 26 are separated, the opening and closing hole 21 is open, and the aforementioned meteorological sensor 22 can pass through the opening and closing hole 21.

[0071] 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 the shape of an inverted "L". A camera 28 is fixedly installed on the equipment frame 27, which can capture images of the water area.

[0072] See Figure 5 It also includes protective components to reduce the impact of waves on the connecting posts of the device, the protective components including:

[0073] In this embodiment, the collar 29 is circular in shape, and its axis coincides with the axis of the mounting plate 32. The collar 29 is rotatably connected to the mounting plate 32, and its upper surface is higher than the upper surface of the mounting plate 32. A toothed ring is integrally formed on the inner wall of the collar 29, and the axis of the toothed ring coincides with the axis of the collar 29. The toothed ring is positioned above the mounting plate 32.

[0074] The second motor (not shown) is enclosed by a protective shell. The non-shaft end is fixed to the lower surface of the mounting plate 32. The shaft of the second motor is arranged vertically and passes through the mounting plate 32. The mounting plate 32 has a through hole for the shaft of the second motor to pass through. A protective gear 30 is fixedly connected to the shaft of the second motor. The axis of the protective gear 30 coincides with the axis of the shaft of the second motor. The protective gear 30 meshes with the gear ring.

[0075] In this embodiment, the protective plate 31, viewed from a top view, is a semi-circular arc in shape and is fixed to the outer circumferential wall of the collar 29. A display screen can be installed on the inner wall of the protective plate 31 to display data monitored by the meteorological sensor.

[0076] It also includes a control module, which is fixedly installed on the inner bottom wall of the storage bucket 6. It is electrically connected to the weather sensor 22, the first motor 15, the second motor, the camera 28 and the display screen through wires. It can receive data from the weather sensor 22 and display it on the display screen. It can also control the first motor 15 and the second motor 30 to operate by remote terminal signals, and can also transmit the monitored weather sensor 22.

[0077] The usage process of this device

[0078] The device is installed on the coast; the base plate 1 is fixedly connected to the coast with bolts. The camera 28 can capture images of the undulating waves at sea and transmit them to the terminal via the wireless transmission module on the control module. The terminal analyzes the hydrological data captured by the camera 28.

[0079] If the terminal needs to collect meteorological data of the location of this device, the meteorological sensor 22 needs to extend from the top of the storage container 6 through the opening and closing hole 21. The specific operation is as follows:

[0080] First, the terminal sends a signal of monitored meteorological data to the control module via a wireless transmission module. Upon receiving the signal, the control module controls the relevant components to operate. The control module causes the first motor 15 to rotate, and the first motor 15 causes the drive shaft 10 to rotate via the driving bevel gear 16 and the driven bevel gear 14. Since the drive disc 11 and the linkage disc 17 are fixedly connected to the drive shaft 10, the drive shaft 10, drive disc 11, and linkage disc 17 rotate as a whole around the axis of the drive shaft 10.

[0081] Let the initial time be Figure 3 In this state, tooth segment B18 on the linkage disk 17 meshes with the linkage gear 20, while tooth segment A12 on the drive disk 11 does not mesh with the drive gear 13. Therefore, the entire assembly only drives the linkage gear 20 to rotate.

[0082] 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 as a whole around the axis of the linkage shaft 19.

[0083] Because the gear ring 23 of the opening and closing device meshes with the control gear 24, the opening and closing device will operate, all the closing plates 26 will separate from each other and open the opening and closing holes 21. Since the tooth segment A12 on the drive disk 11 is not meshed with the drive gear 13, the weather sensor 22 is still in the storage bucket 6 and has not risen.

[0084] 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, and all the closing plates 26 remain separated from each other, while 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. 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 move up and down, the lifting plate 7 rises under the action of the threaded rod 8. The lifting plate 7 connects to the meteorological sensor 22, which extends out from the opening and closing hole 21. The meteorological sensor 22 transmits the meteorological data monitored by each sensor to the control module. If the measured wind direction is A, the control module controls the second motor to operate. Based on the wind direction A and the current position of the protective plate 31, the rotation angle of the second motor is calculated in reverse. Then, the control module controls the second motor to rotate, so that the outer wall of the protective plate 31 faces the wind direction A, thus protecting the display screen. The control module displays the meteorological data and the images captured by the camera on the display screen. When the meteorological sensor 22 is retracted into the storage container 6, the first motor reverses, and the process is the reverse of the above, which will not be described again.

[0085] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
