Description

Technical Field

[0001] The present application relates to the technical field of water conservancy monitoring, and in particular to a water conservancy project monitoring device. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy monitoring devices are mainly used to monitor the water conservancy operations of rivers, lakes, and reservoirs, and to promptly reflect the hydrological characteristics of each water body so that relevant departments can make arrangements to prevent flood disasters.

[0003] There are many types of water conservancy monitoring, among which water level monitoring is one of them. The existing immersion level gauge is usually used to monitor the water level. The immersion level gauge generally includes three main components: a transmitter, a cable and a sensor. When monitoring, the sensor of the immersion level gauge is thrown into the water. The sensor sinks in the water. The measured static pressure of the liquid is proportional to the height of the liquid. The piezoresistive effect of diffused silicon or ceramic sensitive elements is used to convert the static pressure into an electrical signal, thereby completing the monitoring of the liquid level height. However, there are certain shortcomings in use. The cable is soft and easy to store. Although its length can be increased to be suitable for waters of different depths, its soft characteristics make the sensor and cable easy to shake in the water due to the fluctuation of the water flow, which leads to the instability of the measured value. At the same time, when there are fixed foreign objects in the water flow and the water flow is flowing, it is easy to collide with the sensor and cause it to be damaged. Therefore, the present application proposes a water conservancy project monitoring device. Utility Model Content

[0004] The purpose of the present application is to provide a water conservancy project monitoring device to solve the problem that the sensors and cables of existing immersion level meters are easily shaken by the fluctuation of water flow in water, resulting in unstable measurement data, and the sensors are easily damaged by collision with foreign objects.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0006] A water conservancy project monitoring device, comprising:

[0007] Mounting seat;

[0008] The winding lifting member comprises two rotating tubes coaxially rotatably arranged on a mounting seat, the opposite ends of the two rotating tubes are connected to a winding frame, the mounting seat is rotatably penetrated by two rotating rods, both rotating rods are fixed with a conflicting wheel, and a pulley assembly is connected between one of the rotating tubes and one of the rotating rods;

[0009] The sleeve is movably installed through the mounting seat and is placed between the two rotating rods. Both of the abutting wheels are in rolling lap joint with the sleeve, and a socket groove is penetrated and opened on one side of the sleeve.

[0010] The dip-type liquid level gauge includes a transmitter arranged on one of the rotating pipes. A cable is connected to the transmitter. The cable is wound around the winding frame, and its free end movably penetrates through the socket groove and is connected to a sensor located inside the sleeve.

[0011] Furthermore, a support rod is arranged on the mounting seat. The free end of the support rod movably penetrates through the socket groove and is connected to a guide ring, and the cable movably penetrates through the guide ring.

[0012] Furthermore, annular clamping grooves are opened on the outer surfaces of both of the abutting wheels. The cross-section structure of the annular clamping groove is arc-shaped, and the sleeve is located within the two annular clamping grooves.

[0013] Furthermore, first gears are fixedly arranged on both of the rotating rods, and the two first gears are meshed with each other by teeth. A rack is arranged on the sleeve along its length direction, and a second gear meshed with the teeth of the rack is fixedly arranged on one of the abutting wheels.

[0014] Furthermore, a plugging groove is opened at one end of the sleeve, and a plugging block which is in plugging fit with the plugging groove is constructed at the other end of the sleeve.

[0015] Furthermore, a jack is penetrated and opened on the inner wall of the plugging groove. A groove is opened on the plugging block, and a plug rod whose end is in plugging fit with the jack is slidably inserted into the groove. A resisting spring is connected between the groove and the plug rod.

[0016] Furthermore, a plurality of annularly distributed limiting holes are opened on the outer surface of the other rotating pipe. A fixing plate is arranged on the mounting seat, and a limiting rod whose end is in plugging fit with the limiting hole is slidably penetrated through the fixing plate.

[0017] Furthermore, a limiting plate is fixedly arranged on the limiting rod, and a limiting spring sleeved on the limiting rod is installed between the limiting plate and the fixing plate.

The cable of the dip-type liquid level gauge is wound around the winding frame, and the sleeve is arranged and lifted by the abutting of the two abutting wheels. The lifting of the sleeve is synchronized with the unwinding of the cable. When monitoring the water level, the cable is unwound, and the sensor is located inside the sleeve and descends synchronously with the sleeve, so that the sleeve can limit the sensor, making it not easy to shake due to the fluctuation of the water flow, ensuring the stability of its detected value. At the same time, the sleeve protects the sensor from being damaged by the collision of foreign objects. Description of the Drawings

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0029] As Figures 1-8 shown, a water conservancy project monitoring device proposed in an embodiment of this application includes:

[0030] A mounting base 1, the mounting base 1 includes a base, and a gantry is provided on the base. The whole mounting base 1 can be installed on the shore or on a ship, and can be installed either fixedly or movably to meet different monitoring requirements;

[0031] The winding lifting member 2 includes two rotating tubes 201 coaxially arranged on the mounting base 1. A winding frame 202 is connected to the opposite ends of the two rotating tubes 201. Preferably, the winding frame 202 includes two ring plates respectively arranged on the two rotating tubes 201, and a plurality of support rods distributed in a ring shape are connected between the two ring plates. Two rotating rods 203 penetrate through the mounting base 1 rotatably, and a contact wheel 204 is fixedly arranged on each of the two rotating rods 203. A pulley assembly 205 is connected between one of the rotating tubes 201 and one of the rotating rods 203. When the rotating tube 201 rotates, the winding frame 202 can be driven to rotate synchronously. Through the linkage of the pulley assembly 205, when the rotating tube 201 rotates, the rotating rod 203 can be driven to rotate synchronously;

[0032] The sleeve 3 penetrates through the mounting base 1 movably and is located between the two rotating rods 203. Both contact wheels 204 are in rolling contact with the sleeve 3. An insertion groove 4 is formed through one side of the sleeve 3, and a through hole is formed through the portal frame. The sleeve 3 penetrates through the through hole movably. The two contact wheels 204 form a clamping contact with the sleeve 3. When the rotating rod 203 rotates, the two contact wheels 204 roll against the sleeve 3, so that the sleeve 3 can be driven to lift;

[0033] The immersion liquid level gauge 5 includes a transmitter 501 arranged on one of the rotating tubes 201. A cable 502 is connected to the transmitter 501. The cable 502 is wound around the winding frame 202, and its free end penetrates through the insertion groove 4 movably and is connected to a sensor 503 located in the sleeve 3. Preferably, the cable 502 first penetrates through one of the rotating tubes 201 movably and then is wound around the winding frame 202, so that the winding or unwinding of the cable 502 does not affect the transmitter 501. When the water level needs to be monitored, the rotating tube 201 is rotated, so as to drive the winding frame 202 to rotate, thereby unwinding the wound cable 502. Since the sensor 503 is located in the sleeve 3 and the rotating tube 201 rotates synchronously with the rotating rod 203, when the cable 502 is unwound and the sensor 503 descends, the sleeve 3 descends synchronously, so that the sensor 503 is always located in the sleeve 3. After the sensor 503 and the sleeve 3 are both in the water, the sleeve 3 can limit the sensor 503, so that it is not easy to shake due to the fluctuation of the water flow, ensuring the stability of its detection value. At the same time, the sensor 503 is located in the sleeve 3, and the sleeve 3 protects the sensor 503 to prevent the sensor 503 from being damaged by the collision of foreign objects;

[0034] For the overall structure of the device, the cable 502 of the submersible level gauge 5 is wound around the winding frame 202, making it convenient to store the cable 502. A sleeve 3 is provided on the winding lifting member 2, and the sensor 503 is located inside the sleeve 3. When the cable 502 pays out and the sensor 503 sinks, the sleeve 3 descends synchronously. The sleeve 3 plays a role in limiting and protecting the sensor 503. An insertion groove 4 is opened on the sleeve 3, and the cable 502 passes through the insertion groove 4 movably. When storing the cable 502 after the monitoring is completed, as the sleeve 3 rises, the cable 502 can be wound on the winding frame 202 in a timely manner, thus improving the practicability.

[0035] As Figure 7 shown, in some embodiments, a support rod 6 is provided on the mounting base 1. The free end of the support rod 6 passes through the insertion groove 4 movably and is connected with a guide ring 7. The cable 502 passes through the guide ring 7 movably. By providing the support rod 6 and the guide ring 7, the cable 502 can be guided, so that during the pay-out and winding processes, the end of the cable 502 located inside the sleeve 3 always remains vertical and does not rub against the insertion groove 4, playing a role in protecting the cable 502.

[0036] As Figure 7 shown, in some embodiments, annular clamping grooves 8 are opened on the outer surfaces of the two abutting wheels 204. The cross-sectional structure of the annular clamping groove 8 is arc-shaped. The sleeve 3 is located inside the two annular clamping grooves 8. By opening the annular clamping grooves 8, when the two abutting wheels 204 rotate in opposite directions, they can not only lift the sleeve 3, but also limit the sleeve 3, restricting it from sliding horizontally, thus improving the practicability.

[0037] As Figure 2 and Figure 7 shown, in some embodiments, first gears 9 are fixedly provided on both of the two rotating rods 203 and the two first gears 9 are meshed with each other. By providing the two first gears 9, the other rotating rod 203 does not rotate due to the stress of the sleeve 3, so that both of the two rotating rods 203 can apply reverse rotating stress, making the lifting of the sleeve 3 more stable. A rack 10 is provided on the sleeve 3 along its length direction. A second gear 11 meshed with the rack 10 is fixedly provided on one of the abutting wheels 204. Preferably, a first insertion groove is opened on the sleeve 3, and the rack 10 is located inside the first insertion groove. An annular insertion groove is opened on one of the abutting wheels 204 and inside the annular clamping groove 8, and the second gear 11 is fixedly provided inside the annular insertion groove. By the meshing of the second gear 11 and the rack 10, the lifting of the sleeve 3 is made more stable.

[0038] As Figure 8As shown, in some embodiments, a plug-in groove 12 is provided at one end of the sleeve 3, and a plug-in block 13 is constructed at the other end of the sleeve 3 to be plugged into and matched with the plug-in groove 12. Since the water level depths in different waters are different, by opening a plug-in groove 12 at one end of the sleeve 3 and constructing a plug-in block 13 at the other end, the number of sleeves 3 can be increased or decreased according to different depths. Two adjacent sleeves 3 are connected by the plug-in fit of the plug-in groove 12 and the plug-in block 13. It should be noted that the plug-in groove 12 and the plug-in block 13 are tightly plug-fitted.

[0039] like Figure 8 As shown, in some embodiments, a plug hole 14 is formed through the inner wall of the plug slot 12, a groove 15 is formed on the plug block 13, a plug rod 16 whose end is plugged and matched with the plug hole 14 is slidably inserted in the groove 15, and a resistance spring 17 is connected between the groove 15 and the plug rod 16. When the water level in the water area is deeper, more sleeves 3 are required. After multiple sleeves 3 are connected in sequence, the stress on the connection point between the sleeves 3 and the sleeves 3 is relatively large. Through the opening of the plug hole 14, the groove 15, the plug rod 16 and the resistance spring Spring 17, when two adjacent sleeves 3 are plugged in, the insertion rod 16 is first pressed and retracted into the groove 15, and the resistance spring 17 is squeezed, and then the plug block 13 is inserted into the plug groove 12. When the insertion rod 16 is aligned with the socket 14, under the elastic force of the resistance spring 17, the insertion rod 16 is movably inserted into the socket 14, thereby completing the locking to improve the connection strength between the two adjacent sleeves 3. When it is necessary to release the lock, the insertion rod 16 is pressed from the socket 14 so that the insertion rod 16 is separated from the socket 14 to release the lock.

[0040] like Figure 6 As shown, in some embodiments, a plurality of limiting holes 18 distributed in an annular shape are provided on the outer surface of another rotating tube 201, and a fixing plate 19 is provided on the mounting seat 1. A limiting rod 20 with an end portion plugged into and fitted with the limiting hole 18 is slidably penetrated through the fixing plate 19. When the cable 502 is paid out to a certain length so that the sensor 503 is located at the monitoring position, or when an additional sleeve 3 is required, the limiting rod 20 can be movably inserted into the limiting hole 18 at the relative position, thereby locking the rotating tube 201 or the rotating rod 203 and restricting it from rotating, thereby facilitating fixing the position of the sensor 503 and the sleeve 3. At the same time, when the monitoring is completed and the cable 502 is wound and stored, the limiting rod 20 can also be inserted into the corresponding limiting hole 18 to prevent the cable 502 wound on the winding frame 202 from loosening and becoming disorderly.

[0041] like Figure 6As shown, in some embodiments, a limit plate 21 is fixed on the limit rod 20, and a limit spring 22 is installed between the limit plate 21 and the fixed plate 19 and is sleeved on the limit rod 20. When the mounting seat 1 is installed on the hull, the hull has a shaking force due to the water flow when it is moving. Through the set limit plate 21 and the limit spring 22, and the elastic resistance applied by the limit spring 22, the limit rod 20 is more stable after being inserted into the limit hole 18, and will not be detached due to the shaking of the hull, thereby improving practicality.

[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
