Technical Field

[0001] This utility model relates to the field of water level observation technology, specifically an observation device. Background Technology

[0002] Hydrological observation typically involves setting up hydrological observation stations at specific locations or sections along rivers, lakes, and seas under certain conditions to conduct long-term, uninterrupted hydrological observations. After being processed and analyzed, the various hydrological observation data not only serve as the basis for various hydrological forecasts but also as crucial data for studying seabed, riverbed, and bank changes, ocean currents, runoff patterns, and for designing and calculating various water conservancy and coastal engineering projects, as well as for compiling navigation guides.

[0003] Currently, water level monitoring devices are typically installed along riverbanks to facilitate data recording by staff. However, since the crossbar is fixed to a support pole and its end extends above the water surface, it is difficult for people to remove the water level monitoring equipment for inspection and maintenance. Staff also need to climb to the top of the support pole, which is a dangerous operation. Disassembly and installation are also very cumbersome, reducing the effectiveness of the device. Therefore, we have proposed a monitoring device to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an observation device that solves the problems of installing water level observation devices along riverbanks, which is inconvenient for people to remove the water level detection equipment for inspection and maintenance, and requires workers to climb to the top of the support pole, which is a dangerous operation and very cumbersome to disassemble and install.

The bolt passes through the through holes of the cross block and the limiting rod in sequence and is threadedly connected to a nut provided on one side of the limiting rod. One end surface of the limiting rod is in contact with the surface of the cross block.

[0010] Preferably, a photovoltaic power generation device that supplies power to the main body of the water level detection device is fixedly mounted on the surface of the movable sleeve via a bracket.

Detailed Implementation

[0021] 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.

[0022] like Figure 1 As shown:

[0023] An observation device includes a support rod 101 fixedly installed beside a river, a crossbar 106 set at the top of the support rod 101, and a water level detection device body 105 fixed at one end of the crossbar 106 directly above the river surface.

[0024] In this implementation plan: To solve the technical problems existing in the prior art, such as the "currently, water level monitoring devices are generally installed beside the river to facilitate the recording of water level monitoring data by staff. However, since the crossbar 106 is fixed to the support rod 101 and the end of the crossbar 106 extends above the water surface, it is not convenient for people to remove the water level monitoring equipment for inspection and maintenance. Staff also need to climb to the top of the support rod 101, which is quite dangerous and very cumbersome to disassemble and install, reducing the effectiveness of the device." In terms of usage, this problem is obviously a real and difficult problem to solve.

[0025] Furthermore:

[0026] like Figures 1-4 As shown:

[0027] Based on the above: a movable sleeve 102 that can be fitted onto the surface of the support rod 101 is fixed on the crossbar 106;

[0028] The top of the support rod 101 is welded with a top cover plate 103 to limit and block the movable sleeve 102;

[0029] A limiting rod 107 is provided on one side of the crossbar 106, and a connecting rod 108 is fixed on one side of the crossbar 106. One end of the limiting rod 107 is rotatably connected to the surface of the connecting rod 108 via a bearing. A roller sleeve is installed inside the movable sleeve 102, and the movable sleeve 102 slides on the surface of the support rod 101 via the roller sleeve. A cross block 109 is fixed to the bottom outer side of the support rod 101 through an opening in the mounting hole. A bolt 110 is provided between the cross block 109 and the limiting rod 107. The bolt 110 and nut 111 are used to lock the connection between the limiting rod 107 and the cross block 109. The limiting rod 107 and the cross block 109 are both provided with through holes that are compatible with the bolt 110. The bolt 110 passes through the through holes of the cross block 109 and the limiting rod 107 in sequence, and is threadedly connected to the nut 111 provided on one side of the limiting rod 107. One end surface of the limiting rod 107 is in contact with the surface of the cross block 109.

[0030] A photovoltaic power generation device 104 that supplies power to the main body 105 of the water level detection device is fixedly installed on the surface of the movable sleeve 102 by a bracket.

[0031] In this implementation scheme: When the observation device is in use, the crossbar 106 is used to support the main body 105 of the water level detection device, so that the main body 105 of the water level detection device is directly above the water surface for real-time observation of the water level. The main body 105 of the water level detection device can be an ultrasonic water level sensor, specifically model JC18-WL700. During this process, the photovoltaic power generation device 104 can provide power to the main body 105 of the water level detection device in real time.

[0032] When the main body 105 of the water level detection equipment needs to be disassembled, repaired, and maintained, firstly, the nut 111 is loosened by using a wrench (not shown in the figure) to disengage the nut 111 from the bolt 110. Then, the bolt 110 is pulled out from the through hole of the limiting rod 107 and the cross block 109 to release the connection lock between the limiting rod 107 and the cross block 109. When the limiting rod 107 is unlocked, the support between the cross bar 106 and the support rod 101 is released. At this time, by adjusting the angle of the limiting rod 107, the limiting rod 107 rotates on the surface of the connecting rod 108. At this time, the cross bar 106 and the main body 105 of the water level detection equipment fall under their own weight. The movable sleeve 102 on the cross bar 106 slides on the surface of the support rod 101 through the roller sleeve. The roller sleeve can reduce the friction between the movable sleeve 102 and the support rod 101 and improve the smoothness of the movement of the movable sleeve 102.

[0033] During this process, when the crossbar 106, the main body of the water level detection equipment 105, and the photovoltaic power generation equipment 104 components fall to the bottom of the support rod 101, the moving sleeve 102 is driven to make a circular motion around the support rod 101 by the limiting top rod 107 and the crossbar 106. This causes the crossbar 106 to rotate the main body of the water level detection equipment 105 to a certain angle, so that the main body of the water level detection equipment 105, which is located directly above the water surface, rotates to above the ground, making it easier for staff to disassemble, repair, and maintain the main body of the water level detection equipment 105.

[0034] By releasing the locking of the limiting rod 107, the main body 105 of the water level detection device can be lowered to the bottom of the support rod 101, and the main body 105 of the water level detection device, which is located directly above the water surface, can be rotated to the ground. This makes it easier for staff to disassemble, repair and maintain the main body 105 of the water level detection device without having to climb to the top of the support rod 101. This improves the ease of installation and makes the device more effective, meeting actual usage needs.

[0035] The crossbar 106 only supports the main body 105 of the water level detection equipment. The crossbar 106 can be designed to be lightweight, such as hollow, so that it is easier for personnel to hold the limiting top rod 107 to better support the crossbar 106.

[0036] The surface of the limiting rod 107 is in contact with the surface of the cross block 109, so that when the nut 111 is screwed on the surface, the limiting rod 107 is prevented from being squeezed and deformed.

[0037] Furthermore;

[0038] In an optional embodiment, multiple sets of sliders 112 slide inside the cross block 109, and springs 114 arranged symmetrically are fixed between the sliders 112 and the cross block 109. A buffer ring 113 is slidably sleeved on the surface of the support rod 101, and the buffer ring 113 is fixedly connected to the multiple sets of sliders 112.

[0039] The upper surface of the cross block 109 is provided with a sliding groove that matches the slider 112. The slider 112 and the cross block 109 are slidably connected through this sliding groove.

[0040] In this embodiment: the buffer ring 113 is compressed by gravity to squeeze the slider 112, while the slider 112 compresses the spring 114. The spring 114 can provide an impact buffer when the crossbar 106, the water level detection device body 105 and the photovoltaic power generation device 104 fall to the bottom of the support rod 101, thus avoiding damage to the water level detection device body 105 caused by the impact force of the collision.

[0041] It should be noted that the electrical interface of the main body 105 of the water level detection equipment is usually connected to the control box of the photovoltaic power generation equipment 104 by a cable or plug to meet the power supply requirements. The photovoltaic power generation equipment 104 consists of photovoltaic panels, inverters, control boxes, battery energy storage systems and monitoring systems. The specific connection methods and functions adopt conventional technical means and will not be described one by one.

[0042] The working principle and usage process of this utility model are as follows: When the main body 105 of the water level detection device needs to be disassembled, repaired, or maintained, the nut 111 is first loosened by using a wrench (not shown in the figure) to disengage it from the bolt 110. Then, the bolt 110 is pulled out of the through hole of the limiting rod 107 and the cross block 109, releasing the connection lock between the limiting rod 107 and the cross block 109. When the limiting rod 107 is released, the support between the cross bar 106 and the support rod 101 is released. By adjusting the angle of the limiting rod 107, it rotates on the surface of the connecting rod 108. At this time, the cross bar 106 and the main body 105 of the water level detection device fall under their own weight. During this process, the moving sleeve 102 can land on the upper surface of the buffer ring 113, allowing the cross bar 106, the main body 105 of the water level detection device, and the support rod 101 to fall together. When the generator 104 component falls to the bottom of the support rod 101, the moving sleeve 102 moves in a circular motion around the support rod 101 via the limiting top rod 107 and the crossbar 106. This causes the crossbar 106 to rotate the water level detection device body 105 to a certain angle, moving the water level detection device body 105, which was located directly above the water surface, to the ground. This facilitates the disassembly, assembly, and maintenance of the water level detection device body 105 by personnel. Through this operation, by releasing the locking of the limiting top rod 107, it is easy to lower the water level detection device body 105 to the bottom of the support rod 101 and rotate the water level detection device body 105, which was located directly above the water surface, to the ground. This makes it easier for personnel to disassemble, assemble, and maintain the water level detection device body 105 without having to climb to the top of the support rod 101, improving the ease of installation and enhancing the effectiveness of the device to meet practical needs.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
