Description

[0001] The present invention relates to the field of monitoring poles, and in particular to a rotatable river water monitoring pole. Background Art

[0002] A water monitoring pole is an outdoor device used for real-time monitoring of water volume, quality, and safety of water bodies, usually installed along the shore or in the water of rivers, lakes, reservoirs, coastal waters, etc. It often conducts multi-parameter monitoring and can integrate various sensors. Monitoring indicators include: water quality, meteorological data, water volume, images, etc. Moreover, most current water monitoring poles have a real-time data transmission function, uploading data to a cloud platform or monitoring center through wireless technologies such as 4G / 5G, supporting remote viewing and analysis, and sending alarm messages.

[0003] However, for existing water monitoring poles beside rivers, monitoring components such as sensors and cameras are installed on the top crossbar part. In order to obtain accurate data, it is necessary to get as close to the water surface as possible, and its crossbar part needs to extend into the river. During maintenance, it is necessary to disassemble the crossbar part or use an aerial work vehicle, which is time-consuming and laborious, and the maintenance cost is relatively high. If the crossbar extends out for a long distance, there is also a risk of overturning when using an aerial work vehicle, especially beside rivers with soft soil.

[0004] In order to overcome the above problems, a rotatable river water monitoring pole is needed. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotatable river water monitoring pole, which uses a swing arm rod body that can rotate around a support shaft to install monitoring components, facilitating later maintenance and repair, and reducing the operation and maintenance costs.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: A rotatable river water monitoring pole of the present invention includes a pole base, a vertical rod body, and a monitoring component, and further includes a swing arm rod body, a support shaft, and a locking component. The root of the horizontally arranged support shaft is connected to the top of the vertical rod body. The swing arm rod body is an L-shaped rod, and the top corner position of the swing arm rod body is sleeved on the support shaft and can rotate around the axis of the support shaft. The monitoring component is installed on the swing arm of the swing arm rod body facing the river. The locking component can lock the swing arm of the swing arm rod body away from the river on the vertical rod body.

[0007] Further, the locking component includes a locking plate and a locking seat. The locking plate is fixedly connected to one side of the bottom end of the swing arm of the swing arm rod body away from the river, and the locking seat is fixedly connected to the outer wall of the bottom of the vertical rod body. The locking plate is pressed onto the locking seat by bolts to vertically lock the swing arm of the swing arm rod body away from the river.

[0008] Further, it further includes a fixed pulley and a pulling rope. A rope tying ring is provided at the bottom end of the swing arm away from the river. The fixed pulley is installed at the bottom of the vertical rod body, and the head of the pulling rope is tied to the rope tying ring and bypasses the fixed pulley.

[0009] Further, the root of the support shaft is detachably and fixedly connected to the vertical rod body. Two parallel guard plates are provided at the apex position of the swing arm rod body. A sleeve is horizontally arranged between the two guard plates, and the sleeve is rotatably sleeved on the cantilever end of the support shaft.

[0010] Further, a horizontal sleeve is provided at the top of the vertical rod body to sleeve the root of the support shaft. The inner end of the support shaft is coaxially provided with a hexagonal head, and the inner end of the horizontal sleeve is correspondingly provided with a hexagonal middle hole; a threaded middle hole is provided on the end face of the hexagonal head, and the threaded middle hole is locked to the side wall of the vertical rod body by a screw.

[0011] Further, a long slot hole is circumferentially provided in the middle of the sleeve. A limiting frame is radially fixedly connected to the cantilever end of the support shaft, and the limiting frame passes through the long slot hole; a limiting column is also provided between the two guard plates. When the limiting column is blocked by the limiting frame, the swing arm of the swing arm rod body for installing the monitoring component is in the lowest position.

[0012] Further, the limiting frame is of a U-shaped plate structure with an opening facing downwards. A proximity switch is installed on the rear support plate of the limiting frame. The proximity switch can collect the signal of the approach of the limiting column, and the proximity switch is electrically connected to the controller of the electric control system.

[0013] Further, it further includes a solar component. The solar component is installed on the top plate of the vertical rod body through a bracket; the solar component is electrically connected to the electric control system.

[0014] Further, the bottom mounting frame of the bracket is a square frame, and the top plate of the vertical rod body is also a square plate. The two are installed together through multiple bolts that are centrosymmetric.

[0015] Further, climbing ladder bars are provided on the outer wall of the vertical rod body, and multiple climbing ladder bars are symmetrically arranged on the outer wall of the vertical rod body; it further includes a hanging ladder, and the top hook of the hanging ladder can be hooked to the waist plate on the outer side of the top edge of the rod seat.

[0016] Compared with the prior art, the beneficial technical effects of the present invention: The present invention relates to a reversible river water monitoring pole. By using a swing arm rod body rotatably installed by a support shaft, it is possible to select whether to lock the locking component and switch the swing arm of the swing arm rod body facing the river to a working state or a maintenance state. There is no need to use an aerial work vehicle or disassemble the swing arm, and the monitoring component can be repaired and maintained. The reversible river water monitoring pole of the present invention uses a swing arm rod body that can be flipped around a support shaft to install the monitoring component, which is convenient for later maintenance and reduces the operation and maintenance cost.

[0017] In addition, through the locking plate and the locking seat locked by bolts, the locking plate can be firmly pressed against the locking seat, thereby ensuring that the swing arm of the swing arm rod body is always in a reliable working position and avoiding accidental unlocking. By adding a pulley and a pulling rope, the maintenance operator only needs to pull the bottom end of the pulling rope, and the pulling rope will pull one end of the rope loop of the swing arm rod body closer to the vertical rod body, saving manpower and avoiding high-altitude operation. The sleeve is rotatably sleeved on the cantilever end of the support shaft, ensuring a large contact area between the two, and thus achieving a large support strength; the support shaft is tightened in the hexagonal middle hole through the screw connection of the threaded middle hole, which can prevent both the axial movement and the circumferential rotation of the support shaft. Through the cooperation of the limit frame, the long slot hole and the limit post, on the one hand, it prevents the sleeve from disengaging from the cantilever end of the support shaft, and on the other hand, it realizes the control of the limit position of the flipping angle, avoiding equipment damage caused by hard collision between the monitoring component and the rod base. Moreover, by cleverly using the limit frame as a proximity switch bracket, the state information that the swing arm rod body is in the low position can be collected, avoiding accidental electric shock accidents. By adding a solar component, the monitoring pole of the present invention can operate independently from the power grid and can also work without grid power supply; by adopting a square installation interface, the orientation of the photovoltaic panel of the solar component can be conveniently adjusted to obtain the maximum solar irradiance. Through the setting of the hanging ladder and the climbing ladder bars, it is convenient for maintenance personnel to repair and maintain the solar component and the lightning rod at the top of the vertical rod body.

[0021] The core of the present invention is to provide a flip - type river water monitoring pole, which installs a monitoring component by using a swing arm rod body that can rotate around a support shaft, facilitating later maintenance and repair, and reducing operation and maintenance costs.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0025] In a specific embodiment, as Figures 1 to 8 shown, the flipable river water monitoring pole of the present invention includes a pole base 1, a vertical pole body 2 and a monitoring component 7. The root of the vertical pole body 2 is directly welded vertically on the top of the pole base 1, and the pole base 1 protects the bottom of the vertical pole body 2. The monitoring component 7 includes a meteorological sensor, a camera, an LED warning light, GPS positioning, a wireless communication device, and so on.

[0026] The important innovation of the flipable river water monitoring pole of the present invention compared with the existing water level monitoring pole: It further includes a swing arm pole body 3, a support shaft 4 and a locking component. The root of the horizontally arranged support shaft 4 is connected to the top of the vertical pole body 2. The swing arm pole body 3 is an L-shaped rod, and the apex angle of the L-shaped rod is a right angle. The middle position of the swing arm pole body 3 is strengthened by arranging a stay bar 301. The apex angle position of the swing arm pole body 3 is sleeved on the support shaft 4 and can rotate around the axis of the support shaft 4. The monitoring component 7 is installed on the swing arm of the swing arm pole body 3 facing the river. The locking component can lock the swing arm of the swing arm pole body 3 away from the river on the vertical pole body 2. At this time, the swing arm of the swing arm pole body 3 facing the river is horizontally arranged and above the river surface.

[0027] By using the swing arm pole body 3 rotatably installed on the support shaft 4, it is possible to select whether to lock the locking component and switch the swing arm of the swing arm pole body 3 facing the river to the working state or the maintenance state. It is not necessary to use an aerial work vehicle or disassemble the swing arm to repair and maintain the monitoring component 7. The flipable river water monitoring pole of the present invention uses a swing arm pole body that can rotate around the support shaft to install the monitoring component, which is convenient for later maintenance and repair and reduces the operation and maintenance cost.

[0028] In a specific embodiment of the present invention, as Figures 1 to 3 and Figure 5 shown, the locking component includes a locking plate 303 and a locking seat 202. The locking plate 303 is welded and installed on one side of the bottom end of the swing arm of the swing arm pole body 3 away from the river. The locking seat 202 is welded and installed on the outer wall of the bottom of the vertical pole body 2. The locking plate 303 is pressed against the locking seat 202 by bolts and vertically locks the swing arm of the swing arm pole body 3 away from the river. At least two bolts are installed between the locking plate 303 and the locking seat 202.

[0029] Specifically, as Figure 1 andFigure 3 As shown, an angle stiffener plate is also welded between the locking plate 303 and the side wall at the bottom end of the swing arm. The locking seat 202 is a C-shaped plate seat. Bolts can pass through and be locked with nuts, or threaded holes can be directly provided on the top plate of the locking seat 202.

[0030] Obviously, the locking assembly can also adopt the method of locking the swing arm of the swing arm rod body 3 by using a locking pin after the pin sleeve coincides. Similar simple replacement methods all fall within the protection scope of the present invention.

[0031] Through the locking plate 303 and the locking seat 202 locked by bolts, the locking plate 303 can be firmly pressed against the locking seat 202, thereby ensuring that the swing arm of the swing arm rod body 3 is always in a reliable working position and avoiding accidental unlocking.

[0032] In a specific embodiment of the present invention, as Figure 2 and Figure 5 shown, the flipable river water monitoring pole of the present invention further includes a fixed pulley 5 and a pull rope 6. A rope tying ring is provided at the bottom end of the swing arm of the swing arm rod body 3 away from the river. The fixed pulley 5 is installed at the bottom of the vertical rod body 2. The head of the pull rope 6 is tied to the rope tying ring, and the other end of the pull rope 6 bypasses the fixed pulley 5 and extends downward and outward, and is pulled by maintenance personnel to achieve displacement switching.

[0033] By adding the pulley 5 and the pull rope 6, maintenance personnel only need to pull the bottom end of the pull rope 6, and the pull rope 6 will pull one end of the rope tying ring of the swing arm rod body 3 close to the vertical rod body 2, saving manpower and avoiding working at the same height.

[0034] In a specific embodiment of the present invention, as Figures 6 to 8 shown, the root of the support shaft 4 is detachably and fixedly connected to the vertical rod body 2. Two parallel guard plates 302 are provided on the inner side at the top corner position of the swing arm rod body 3. The guard plates 302 are welded to both sides of the square tube of the swing arm rod body 3. A sleeve 304 is horizontally arranged between the two guard plates 302, and the sleeve 304 is rotatably sleeved on the cantilever end of the support shaft 4.

[0035] Specifically, as Figures 6 to 8 shown, a horizontal sleeve is provided at the top of the vertical rod body 2 to socket the root of the support shaft 4. The horizontal sleeve is horizontally welded in the inner cavity at the top of the vertical rod body 2 and opens at one end facing the support shaft 4. The inner end of the support shaft 4 is coaxially provided with a hexagonal head 402, and the inner end of the horizontal sleeve is correspondingly provided with a hexagonal middle hole. The hexagonal head 402 is inserted into the hexagonal middle hole in a matching manner. A threaded middle hole 403 is opened at the center position of the end face of the hexagonal head 402, and the threaded middle hole 403 is locked to the side wall of the vertical rod body 2 by a screw to prevent the axial movement of the support shaft 4.

[0036] It can be rotatably sleeved on the cantilever end of the support shaft 4 through the sleeve 304, ensuring a large contact area between the two, and thus achieving a large support strength; the support shaft 4 is tightened in the hexagonal middle hole through the screw connection threaded middle hole 403, which can prevent both the axial movement and the circumferential rotation of the support shaft 4.

[0037] In a specific embodiment of the present invention, as Figures 6 to 8 shown, a long slot hole 305 is circumferentially opened in the middle of the sleeve 304, and a limiting frame 401 is fixedly connected radially to the cantilever end of the support shaft 4. The root of the limiting frame 401 is welded to the outer wall of the support shaft 4. The limiting frame 401 passes through the long slot hole 305, and relative circumferential sliding can occur between the two by a certain angle. A limiting column 306 is also provided between the two guard plates 302, and both ends of the limiting column 306 are welded to the inner side wall of the guard plate 302. The limiting column 306 is located in the front lower part of the guard plate 302. When the limiting column 306 is blocked by the limiting frame 401, the swing arm of the swing arm rod body 3 where the monitoring component 7 is installed is in the lowest position, that is, in the maintenance state.

[0038] Specifically, as Figures 6 to 8 shown, the limiting frame 401 is a U-shaped plate structure with an opening facing downwards. A proximity switch 11 is installed on the rear support plate of the limiting frame 401, and a through hole is opened at the position of the induction end of the proximity switch 11 on the front support plate of the limiting frame 401. The proximity switch 11 can collect the signal of the approach of the limiting column 306, and the proximity switch 11 is electrically connected to the controller of the electric control system. The electric control box of the electric control system is arranged in the pole base 1, and a maintenance door is opened on the side wall of the pole base 1, which is not shown in the drawing.

[0039] Specifically, after the controller receives the signal of the approach of the limiting column 306 collected by the proximity switch 11, it outputs an action instruction to cut off the power supply of the monitoring component 7, preventing an electric shock accident caused by continuous power supply after the swing arm rod body 3 accidentally drops to the bottom end.

[0040] Through the cooperative setting of the limiting frame 401, the long slot hole 305 and the limiting column 306, on the one hand, it prevents the sleeve 304 from slipping off the cantilever end of the support shaft 4, and on the other hand, it realizes the control of the limit position of the flipping angle, avoiding equipment damage caused by hard collision between the monitoring component 7 and the pole base 1. Moreover, the limiting frame 401 is cleverly used as the bracket of the proximity switch 11, which can collect the state information of the swing arm rod body 3 being in the low position, avoiding an accidental electric shock accident.

[0041] In a specific embodiment of the present invention, as Figures 1 to 5 shown, the present invention's flipable river water monitoring pole further includes a solar energy component 9, and the solar energy component 9 is installed on the top plate of the vertical rod body 2 through a bracket 901. The solar energy component 9 is electrically connected to the electric control system to charge the battery.

[0042] Specifically, as Figures 1 to 5 shown, the bottom mounting frame of the bracket 901 is a square frame, and the top plate of the vertical rod body 2 is also a square plate. The two are installed together through multiple bolts that are centrosymmetric.

[0043] By adding the solar component 9, the monitoring pole of the present invention can operate independently from the power grid, that is, it can also work without power grid power supply; by adopting a square installation interface, the orientation of the photovoltaic panel of the solar component 9 can be conveniently adjusted to obtain the maximum solar irradiation.

[0044] In a specific embodiment of the present invention, as Figures 1 to 5 shown, ladder rungs 201 are provided on the outer wall of the vertical rod body 2, and multiple ladder rungs 201 are symmetrically arranged on the outer wall of the vertical rod body 2. The flipable river water monitoring pole of the present invention further includes a hanging ladder 10, and the top hook of the hanging ladder 10 can be hooked to the waist plate on the outer side of the top edge of the pole base 1. The hanging ladder 10 is not usually placed on the pole base 1 and is only hung for use when maintenance personnel are working.

[0045] Through the arrangement of the hanging ladder 10 and the ladder rungs 201, it is convenient for maintenance personnel to repair and maintain the solar component 9 and the lightning rod at the top of the vertical rod body 2.

[0046] When the flipable river water monitoring pole of the present invention is working: in the normal working state, the monitoring component 7 is on the transverse swing arm of the swing arm rod body 3 that horizontally extends above the river surface and can normally monitor the water surface. When it needs to be repaired and maintained, the transverse swing arm of the swing arm rod body 3 needs to be lowered. First, the operator binds the pull rope 6 to the rope loop of the swing arm rod body 3 and bypasses the fixed pulley 5, and one operator holds the rope end and pulls it. Another operator uses a wrench tool to remove the bolts on the locking plate 303 so that the locking plate 303 is disengaged from the locking seat 202. The operator holding the rope slowly releases the pull rope 6. Because one end of the transverse swing arm of the swing arm rod body 3 is heavier, the vertical end of the swing arm rod body 3 slowly flips backward until the limit post 306 abuts against the limit frame 401 and the swing arm rod body 3 stops flipping. At this time, the monitoring component 7 is lowered to the side of the pole base 1 facing the river along with the transverse swing arm of the swing arm rod body 3, and the operator can perform repair and maintenance without climbing high. At the same time, after the proximity switch 11 collects the signal that the limit post 306 abuts against the limit frame 401, that is, the state information that the swing arm rod body 3 is in the low position, the controller cuts off the power supply of the monitoring component 7 to avoid accidental electric shock accidents. If it is necessary to power on for detecting the monitoring component 7, the bypass switch in the electric control box can be manually opened. After the repair and maintenance are completed, pull the pull rope 6, the swing arm rod body 3 slowly flips in the reverse direction, the transverse swing arm of the swing arm rod body 3 gradually returns to the horizontal, and the bolts on the locking plate 303 are reinstalled so that the locking plate 303 is pressed against the locking seat 202 again.

[0047] In summary, for the invertible river water monitoring pole of the present invention, by using the swing arm rod body 3 rotatably installed by the support shaft 4, it is possible to select whether to lock the locking component and switch the swing arm of the swing arm rod body 3 facing the river to the working state or the maintenance state. There is no need to use an aerial work vehicle or disassemble the swing arm, and the monitoring component 7 can be repaired and maintained. The invertible river water monitoring pole of the present invention uses a swing arm rod body that can be flipped around the support shaft to install the monitoring component, which is convenient for later maintenance and repair and reduces the operation and maintenance costs. In addition, through the locking plate 303 and the locking seat 202 locked by bolts, the locking plate 303 can be firmly pressed against the locking seat 202, thereby ensuring that the swing arm of the swing arm rod body 3 is always in a reliable working position and avoiding accidental unlocking. By adding a pulley 5 and a pull rope 6, the maintenance operator only needs to pull the bottom end of the pull rope 6, and the pull rope 6 pulls one end of the rope loop of the swing arm rod body 3 closer to the vertical rod body 2, saving manpower and avoiding high-altitude operations. By the sleeve 304 rotatably sleeved on the cantilever end of the support shaft 4, a large contact area between the two is ensured, and thus a large support strength is achieved; by tightening the support shaft 4 in the hexagonal middle hole through the screw connection threaded middle hole 403, axial movement and circumferential rotation of the support shaft 4 can be prevented. Through the cooperation of the limit frame 401, the long slot hole 305 and the limit post 306, on the one hand, the sleeve 304 is prevented from coming off the cantilever end of the support shaft 4, and on the other hand, the limit position control of the flipping angle is realized, avoiding equipment damage caused by a hard collision between the monitoring component 7 and the rod base 1. Moreover, by cleverly using the limit frame 401 as the bracket of the proximity switch 11, the state information of the swing arm rod body 3 being in the low position can be collected, avoiding accidental electric shock accidents. By adding a solar component 9, the monitoring pole of the present invention can operate independently of the power grid and can also work without grid power supply; by using a square installation interface, the orientation of the photovoltaic panel of the solar component 9 can be conveniently adjusted to obtain the maximum solar irradiation. Through the setting of the hanging ladder 10 and the ladder rungs 201, it is convenient for maintenance personnel to repair and maintain the solar component 9 and the lightning rod at the top of the vertical rod body 2.
