Description

Technical Field

[0001] This utility model relates to the field of hydrological monitoring technology, and in particular to a hydrological monitoring device. Background Technology

[0002] Hydrological monitoring devices are instruments, equipment, and technical systems used to observe and analyze hydrological phenomena and acquire hydrological information. They typically consist of a radar level gauge body, a data acquisition unit, a communication module, and a control center.

[0003] The existing hydrological monitoring devices are located in relatively fixed positions after installation, making it inconvenient to move the level gauges that extend to the water surface to the shore, and also inconvenient to inspect and maintain the level gauges.

[0004] An existing patent (publication number: CN220337913U) discloses a hydrological monitoring device. By setting up an installation mechanism, the screw-on fixing bolts are released from the fixing sleeve, and the support fixing component is freed from the limiting fixation. This allows the rotating rod to rotate downwards and can rotate and move the radar level gauge located above the water surface to above the water's edge, facilitating the inspection and maintenance of the radar level gauge.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the rotating column and fixed column proposed in these patents only rotate through a simple plug-in connection. This makes it inconvenient to restrict the rotation of the radar level gauge during maintenance or repair when it is moved to the shore. It also makes it difficult to maintain stability during maintenance and repair, thus affecting the stable progress of the radar level gauge maintenance work.

[0006] Therefore, a hydrological monitoring device is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a hydrological monitoring device that can solve the problem in the existing patents where the rotating column and the fixed column rotate only through a simple plug-in connection. This makes it inconvenient to restrict the rotation of the radar level gauge when it is rotated to the shore for inspection and maintenance, and it is also inconvenient to maintain stability during the inspection and maintenance process, thus affecting the stable progress of the radar level gauge inspection and maintenance work.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a hydrological monitoring device, comprising a support column, a control box, a photovoltaic panel and a radar level gauge body, wherein a support rod is provided on the front side of the support column, the radar level gauge body is fixedly connected to the front side of the support rod, a fixing plate is provided at the bottom of the support column, a rotating mechanism is provided at the top of the fixing plate, and a support mechanism is provided at the bottom of the support rod.

[0009] The rotating mechanism includes a limiting pin, a fixing sleeve, two first through holes, two second through holes, and two fixing plates. The top of the fixing plate is fixedly connected to the bottom of the support column, and the bottom of the fixing sleeve is fixedly connected to the top of the fixing plate. The fixing plate is rotatably connected inside the fixing sleeve. The first through holes are opened on the front and rear sides of the top of the fixing sleeve, and the second through holes are opened on the front and rear sides of the top of the fixing plate. The bottom of the limiting pin passes through the front first through hole and extends into the interior of the front second through hole.

[0010] Preferably, a fixing block is fixedly connected to both sides of the limiting pin, and a first screw is provided on the top of the fixing block. The bottom of the first screw passes through the fixing block and is connected to the internal thread of the fixing sleeve.

[0011] Preferably, a throttle handle is fixedly connected to the surface of the support column, and the number of the throttle handles is four and they are evenly distributed on the surface of the support column.

[0012] Preferably, the top of the fixing plate is provided with fixing holes, and the number of fixing holes is several and evenly distributed inside the fixing plate.

[0013] Preferably, the support mechanism includes two first rotating frames, a strut, a second screw, and a connecting block. The strut is rotatably connected to the inside of the first rotating frame on the side closest to the first rotating frame. The top of the top first rotating frame is fixedly connected to the bottom of the strut, and the rear side of the bottom first rotating frame is fixedly connected to the front side of the connecting block.

[0014] Preferably, a limiting frame is fixedly connected to the front side of the support column, the connecting block is movably inserted into the inside of the limiting frame, and the rear side of the second screw passes through the connecting block and is threadedly connected to the inside of the limiting frame.

[0015] Preferably, a second rotating frame is rotatably connected to the surface of the support rod, and the rear side of the second rotating frame is fixedly connected to the front side of the support column.

[0016] Preferably, a pull rod is fixedly connected to the front side of the connecting block.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a rotating mechanism so that the fixed plate can rotate. By removing the first screw and pulling the limiting pin out from the first and second through holes on the front side, the support column can be rotated 180 degrees to rotate the radar level gauge body to the shore. Then, the limiting pin is inserted into the first and second through holes on the rear side, which can conveniently limit the rotation of the radar level gauge body after rotation.

[0019] 2. This application sets up a support mechanism so that the struts and supports can be rotated and lowered, thereby lowering the radar level gauge body. Then, by inserting limit pins into the first and second rear through holes, the rotation of the radar level gauge body is restricted, thus avoiding random rotation during the maintenance of the radar level gauge body, which would affect the efficiency of maintenance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A hydrological monitoring device includes a support column 1, a control box 3, a photovoltaic panel 4, and a radar level gauge body 15. A support rod 5 is provided on the front side of the support column 1, and the radar level gauge body 15 is fixedly connected to the front side of the support rod 5. A fixing plate 7 is provided at the bottom of the support column 1, a rotating mechanism 8 is provided at the top of the fixing plate 7, and a support mechanism 6 is provided at the bottom of the support rod 5.

[0029] The rotating mechanism 8 includes a limiting pin 801, a fixing sleeve 802, two first through holes 803, two second through holes 804, and two fixing plates 805. The top of the fixing plate 805 is fixedly connected to the bottom of the support column 1, and the bottom of the fixing sleeve 802 is fixedly connected to the top of the fixing plate 7. The fixing plate 805 is rotatably connected inside the fixing sleeve 802. The first through holes 803 are opened on the front and rear sides of the top of the fixing sleeve 802, and the second through holes 804 are opened on the front and rear sides of the top of the fixing plate 805. The bottom of the limiting pin 801 passes through the front first through hole 803 and extends into the interior of the front second through hole 804.

[0030] In this embodiment: First, the radar level gauge body 15 is installed in the required position using external bolts through the fixing holes 10 of the fixing plate 7. The support rod 5 is connected to the radar level gauge body 15 to monitor hydrological data. The control box 3 processes the data, and the photovoltaic panel 4 provides power. When the radar level gauge body 15 needs to be repaired, under normal conditions, the limit pin 801 engages with the front first through hole 803 and the front second through hole 804, and the first screw 11 restricts the rotation of the support column 1. First, remove the first screw 11, pull out the limit pin 801, and rotate the support column 1 180 degrees by holding the handle 9 to move the radar level gauge body 15 to the shore. Then, insert the limit pin 801 into the rear first through hole 803 and the rear second through hole 804 to restrict the rotation of the fixing plate 805, thereby controlling the rotation of the support column 1, the support rod 5, and the radar level gauge body 15. The radar level gauge body 15 is restricted from rotation. The connecting block 604 is fixed in the limiting frame 2 by the second screw 603. After removing the second screw 603, the pull rod 13 is held by hand. By utilizing the connection between the support rod 602 and the first rotating frame 601, and with the support and guidance of the second rotating frame 14 on the support rod 5, the radar level gauge body 15 can be lowered. At this time, the limiting pin 801 stabilizes the radar level gauge body 15, which facilitates the stable and efficient maintenance work. This solves the problem proposed in the existing patent that the rotating column and the fixed column can only rotate through a simple plug-in connection. When the radar level gauge is rotated to the shore for maintenance, it is inconvenient to restrict its rotation and maintain stability during the maintenance process, which affects the stable progress of the radar level gauge maintenance work.

[0031] Specifically, such as Figure 2 As shown, both sides of the limiting pin 801 are fixedly connected to the fixing blocks 12. The top of the fixing block 12 is provided with a first screw 11. The bottom of the first screw 11 passes through the fixing block 12 and is connected to the internal thread of the fixing sleeve 802.

[0032] Specifically, such as Figure 2 As shown, a throttle 9 is fixedly connected to the surface of the support column 1. There are four throttles 9, which are evenly distributed on the surface of the support column 1.

[0033] Specifically, such as Figure 2 As shown, the top of the fixed plate 7 is provided with a number of fixing holes 10, which are evenly distributed inside the fixed plate 7.

[0034] In this embodiment: Under normal conditions, the limiting pin 801 passes through the first through hole 803 on the front side of the top of the fixing sleeve 802 and extends into the second through hole 804 on the front side of the top of the fixing plate 805. The first screws 11 on the fixing blocks 12 on both sides of the limiting pin 801 are threadedly connected to the inside of the fixing sleeve 802, which restricts the rotation of the support column 1 and keeps the radar level gauge body 15 stable. By removing the first screws 11, the limiting pin 801 can be pulled upward out of the front first through hole 803 and the front second through hole 804, so that the support column 1 can be rotated by hand using the handle 9. The fixing plate 7 can be easily fixed by using an external bolt through the fixing hole 10, thereby facilitating the stable fixing of the fixing plate 805, the fixing sleeve 802 and the support column 1.

[0035] Specifically, such as Figure 3 As shown, the support mechanism 6 includes two first rotating frames 601, a support rod 602, a second screw 603, and a connecting block 604. The support rod 602 is rotatably connected to the inside of the first rotating frame 601 on the side near the first rotating frame 601. The top of the top first rotating frame 601 is fixedly connected to the bottom of the support rod 5, and the rear side of the bottom first rotating frame 601 is fixedly connected to the front side of the connecting block 604.

[0036] Specifically, such as Figure 3 and Figure 5 As shown, the front side of the support column 1 is fixedly connected to the limiting frame 2, the connecting block 604 is movably inserted into the inside of the limiting frame 2, and the rear side of the second screw 603 passes through the connecting block 604 and is threadedly connected to the inside of the limiting frame 2.

[0037] Specifically, such as Figure 4 As shown, a second rotating frame 14 is rotatably connected to the surface of the support rod 5, and the rear side of the second rotating frame 14 is fixedly connected to the front side of the support column 1.

[0038] Specifically, such as Figure 3 As shown, a pull rod 13 is fixedly connected to the front side of the connecting block 604.

[0039] In this embodiment: after the connecting block 604 is released from its limit by removing the second screw 603, the connecting block 604 is rotatably connected to the support rod 602 through the bottom first rotating frame 601, the support rod 602 is rotatably connected to the support rod 5 through the top first rotating frame 601, and the support rod 5 is rotatably connected to the support column 1 through the second rotating frame 14. After the connecting block 604 is lowered by holding the pull rod 13, the radar level gauge body 15 can be lowered to facilitate the inspection and maintenance of the radar level gauge body 15.

[0040] Working principle: First, the fixed plate 7 is securely installed in the required position using external bolts through the evenly distributed fixing holes 10 on the top of the fixed plate 7. The support rod 5 on the front side of the support column 1 is fixedly connected to the radar level gauge body 15 for monitoring hydrological data. The control box 3 processes the monitoring data and performs other operations. The photovoltaic panel 4 absorbs solar energy and converts it into electrical energy to power the device. The hydrological monitoring device is a mature technology that has been published. The specific mechanism will not be elaborated here. When the radar level gauge body 15 needs to be inspected and maintained, under normal conditions, the limit pin 801 passes through the first through hole 803 on the front side of the top of the fixed sleeve 802 and extends into the second through hole 804 on the front side of the top of the fixed plate 805. The first screw 11 on the side fixing block 12 is threadedly connected to the inside of the fixing sleeve 802, restricting the rotation of the support column 1. At this time, first remove the first screw 11 to release the fixing restriction on the limit pin 801. Pull the limit pin 801 upward out of the front first through hole 803 and the front second through hole 804. Then, the operator holds the four handles 9 evenly distributed on the surface of the support column 1 and rotates the support column 1 180 degrees. Because the fixing plate 805 is rotatably connected inside the fixing sleeve 802, the support column 1 can rotate smoothly, thereby driving the support rod 5 and the radar level gauge body 15 at the front end to rotate to the shore. After the radar level gauge body 15 rotates to the shore, insert the limit pin 801 into the first through hole on the rear side of the top of the fixing sleeve 802. The second through hole 804 on the rear side of the top of the fixed plate 805 and the 803 and fixed plate 805 are connected. At this time, the limiting pin 801 again restricts the rotation of the support column 1, so that the radar level gauge body 15 is stably stopped at the shore position. Then, in the support mechanism 6, the connecting block 604 on the rear side of the bottom first rotating frame 601 is movably inserted into the limiting frame 2 on the front side of the support column 1, and is fixed by the second screw 603 passing through the connecting block 604 and the internal thread connection of the limiting frame 2. At this time, the second screw 603 is removed to release the fixing restriction on the connecting block 604. The operator holds the pull rod 13 fixedly connected to the front side of the connecting block 604 and uses the rotational connection between the support rod 602 and the first rotating frame 601 to rotate the support rod 602 and the support rod 5. Because the rear side of the second rotating frame 14, which is rotatably connected to the surface of the support rod 5, is fixedly connected to the front side of the support column 1, it provides certain support and rotation guidance for the support rod 5. Therefore, the radar level gauge body 15 can be smoothly lowered to a position that is convenient for inspection and maintenance. At this time, the radar level gauge body 15 is in a stable state due to the rotation restriction effect of the previous limiting pin 801, which facilitates the maintenance personnel to carry out stable inspection and maintenance work. This effectively solves the problem proposed in the existing patent that the rotating column and the fixed column only rotate through a simple plug-in connection. When the radar level gauge is rotated to the shore for inspection and maintenance, it is inconvenient to restrict its rotation and maintain stability during the inspection and maintenance process, which affects the stable progress of the radar level gauge inspection and maintenance work.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
