Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrological monitoring technology, and in particular to an adaptive water level and temperature monitoring device. Background Technology
[0002] There is an existing Chinese utility model patent with publication number CN211452655U, entitled "A Water Temperature Monitoring Device." This patent discloses a temperature sensor mounted on a positioning component, which can float on the water surface to confine the temperature sensor to a predetermined depth below the water surface. The positioning component includes a floating platform and a counterweight. The counterweight and the floating platform are fixed together by bolts, or they can be detachably assembled to facilitate replacement of the counterweight and adapt the positioning component to different water levels for temperature monitoring. However, when adjusting the predetermined depth of the temperature sensor below the water surface, the counterweight must be replaced, requiring the use of counterweights of different heights. This not only increases costs but also adds the extra work of managing idle counterweights. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an adaptive water level and temperature monitoring device that eliminates the need for multiple counterweights, thereby reducing costs and eliminating the need to manage idle counterweights.
[0004] To achieve the aforementioned objectives of this utility model, the technical solution for the adaptive water level and temperature monitoring device is as follows:
[0005] An adaptive water level and temperature monitoring device includes a hollow tube with a water inlet on its lower side and a flange on its top. A housing is located on the top surface of the flange, and an automatic telescopic cable reel is located inside the housing. One end of the cable on the automatic telescopic cable reel is connected to a controller, and the other end extends into the hollow tube and is connected to a temperature sensor. A counterweight is located on the top surface of the temperature sensor, and a float is located above the counterweight. A through hole for the cable to pass through is located in the middle of the float, and a pair of clamps for holding the cable are detachably connected to the top of the float.
[0006] Preferably, the clamp is a semi-conical body with a larger top and a smaller bottom. The top surface of the float has a conical hole for receiving the semi-conical body, the top surface of the semi-conical body has a bolt through hole for connecting the float, and the flat sidewall of the semi-conical body has a slot for squeezing the cable.
[0007] Preferably, the counterweight is composed of two rectangular plates connected by bolts. The sidewalls of the rectangular plates are provided with cable passage grooves. The radius of the cable passage grooves is larger than the radius of the cable and smaller than the radius of the temperature sensor.
[0008] Preferably, a grid plate is provided at the water inlet.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. The clamp holds and fixes the cable, connecting the cable and float into a single unit. Under the action of the counterweight, it can adapt to changes in water level and maintain the temperature sensor at the set depth. When it is necessary to change the set depth of the temperature sensor, it can be adjusted by loosening the clamp, eliminating the need for multiple counterweights, thus reducing costs and eliminating the need for managing idle counterweights.
[0011] 2. Water inlet holes are opened on the side wall of the hollow tube to introduce water into the inner cavity of the hollow tube, and the water level inside and outside the hollow tube is kept at the same height, thus forming a relatively closed monitoring environment. This reduces the fluctuation of the float and the surge of the temperature sensor, which helps to improve the accuracy of water temperature monitoring.
[0012] 3. A grid plate is installed at the water inlet to prevent larger organisms or debris from entering the hollow tube, ensuring that the monitoring environment is not disturbed. Attached Figure Description

Detailed Implementation
[0019] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0020] like Figure 1-5As shown, an adaptive water level and temperature monitoring device includes a hollow tube 1 with an inlet 11 on its lower side. When the hollow tube is fixed to the riverbed, river water enters the inner cavity of the hollow tube through the inlet. Under the same air pressure, the water level inside and outside the hollow tube remains consistent. A grid plate 2 is installed at the inlet to prevent larger organisms or debris from entering the hollow tube, ensuring that the monitoring environment is undisturbed. A flange 12 is fixed to the top of the hollow tube, and the top surface of the flange is detachably connected to a housing 3 by bolts. An automatic telescopic cable reel 4 is installed inside the housing. The automatic telescopic cable reel is existing technology and can be purchased online (Heye Cable Reel). One end of the cable 41 of the automatic telescopic cable reel is connected to the controller, and the other end extends into the inner cavity of the hollow tube and is connected to a temperature sensor 5. A counterweight 6 is installed on the top surface of the temperature sensor. The counterweight is composed of two rectangular plates 61 connected by bolts. Cable grooves are opened on the side walls of the rectangular plates for the cable to pass through. 62. The radius of the cable tray is greater than the radius of the cable but less than the radius of the temperature sensor. The counterweight has a simple structure and is easy to install. The counterweight presses on the temperature sensor to keep the cable vertical. A float 7 is set above the counterweight. A through hole 71 for the cable to pass through is opened in the middle of the float. A pair of clamping plates 8 for holding the cable are detachably connected to the top of the float. The clamping plates are semi-conical bodies with a larger top and a smaller bottom. A conical hole 72 for receiving the semi-conical body is opened on the top surface of the float. A bolt through hole 81 for connecting the float is opened on the top surface of the semi-conical body. A slot 82 for squeezing the cable is opened on the flat side wall of the semi-conical body. The radius of the slot is 1mm smaller than the radius of the cable. When the two slots are closed, they can squeeze the insulation layer (rubber) of the cable to deform, thereby generating friction to lock the cable. The conical hole can accurately position the semi-conical body to ensure that the two semi-conical bodies can firmly and reliably clamp the cable.
[0021] The specific working process and principle of this utility model are as follows: A hollow tube is installed in a river, and the water passage ensures that the water level is consistent inside and outside the hollow tube. A float floats on the water surface, suspending the temperature sensor below the water surface to set the depth. When the water level drops, the automatic telescopic reel automatically releases the line under the action of the counterweight, and the float descends with the water level. When the water level rises, the float rises with the water level, and the automatic telescopic reel automatically retracts the line, always maintaining a constant relative distance between the temperature sensor and the water surface. When it is necessary to adjust the set depth of the temperature sensor, the bolts between the housing and the flange are removed, and the housing, along with the automatic telescopic reel, float, counterweight, etc., are taken out as a whole. Loosening one of the clamps allows the distance from the temperature sensor to the bottom of the float to be adjusted by pulling the cable to meet the set requirements. This eliminates the need for multiple counterweights, thereby reducing costs and eliminating the need for managing idle counterweights.
