Description

Technical Field

[0001] This utility model relates to the field of water level gauge installation technology, specifically a dam water level gauge installation component. Background Technology

[0002] A dam water level gauge is an instrument used to measure and display the water level height inside a dam. It is mainly used to monitor changes in the water level of the dam to ensure its safe operation. When applied in water conservancy projects, dam water level gauges can help engineers predict and control water flow and prevent disasters such as floods.

[0003] Existing radar level gauges used for dam water level monitoring are often installed in a way that is too long. Since radar level gauges are non-contact, they need to be fixed to the water surface of the dam or river channel using mounting components to transmit and receive radar signals. Furthermore, strong winds can easily blow across the water surface, causing the horizontal bars on the components to sway and the level gauge at the end of the bars to shake as well, making it difficult to maintain stability. Additionally, because the level gauge is usually located at the end of the horizontal bars, far from the dam bank and high above the water surface, and the orientation of the mounting components cannot be changed or adjusted, maintenance of the level gauge is troublesome and time-consuming, making it inconvenient for repairs. Utility Model Content

[0004] The purpose of this utility model is to provide a dam water level gauge installation component to solve the problems mentioned in the background art, such as the water level gauge on the installation component easily shaking in windy weather, thus affecting the stability of the water level gauge, and the water level gauge being troublesome and time-consuming to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dam water level gauge installation assembly, comprising a base, a bottom pipe fixedly connected to the top of the base, a top pipe provided at the top of the bottom pipe, a sleeve provided at the top of one side wall of the top pipe, a telescopic rod provided inside the sleeve, a water level gauge installed at one end of the telescopic rod, a cover box fixedly connected to the end of the sleeve away from the top pipe, a diagonal tie rod fixedly connected to the top of the sleeve, a cover cylinder provided at the top of the other side wall of the top pipe, an electric push rod installed inside the cover cylinder, an insertion tube provided at the bottom of the top pipe, an internal gear ring provided at the bottom of the inner wall of the insertion tube, a spur gear meshing with the inner wall of the internal gear ring, and a forward and reverse motor installed at the bottom of the inner side of the bottom pipe.

[0006] Preferably, the top end of the bottom tube and the bottom end of the top tube are both fixedly connected to ear plates, and fastening bolts are movably passed through both sides of the ear plates, with nuts threadedly fitted at the bottom ends of the fastening bolts.

[0007] Preferably, the top end of the insertion tube is fixedly connected to the ear plate at the bottom end of the top tube, and the insertion tube is movably embedded in the bottom tube.

[0008] Preferably, a photovoltaic module is installed at the top of the jacking pipe, and the photovoltaic module is electrically connected to the electric push rod and the forward and reverse motor through a fixed inverter.

[0009] Preferably, the end of the telescopic rod furthest from the water level gauge is fixedly connected to the output end of the electric push rod, and the telescopic rod is slidably connected to the sleeve via the electric push rod.

[0010] Preferably, the cover box has openings on both the front and bottom, and the water level gauge is movably connected to the cover box via a telescopic rod.

[0011] Preferably, the output end of the reversible motor is fixedly connected to the middle part of the spur gear, and the spur gear is meshed with the internal gear ring through the reversible motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This dam water level gauge installation assembly, through the installation of a sleeve, telescopic rod, and electric push rod, allows the horizontal bar on the installation assembly to be of a certain length. In the event of strong winds on the dam, the telescopic rod can be retracted into the sleeve by the electric push rod, reducing the probability of the water level gauge swaying on the installation assembly. At the same time, in conjunction with the cover box located at the end of the sleeve, the water level gauge can be embedded in the cover box, thereby protecting the water level gauge and helping it maintain a stable state in strong winds.

[0014] This dam water level gauge installation assembly, through the setting of a tube, bottom tube, internal gear ring, spur gear, and forward and reverse motor, enables the top tube on the installation assembly and the structure on which the top tube is located to rotate horizontally along the bottom tube at the top of the fixed base under the meshing action of the spur gear and the internal gear ring. This allows the water level gauge suspended on the water surface of the dam to rotate to the ground where the dam is located, thereby facilitating the maintenance of the water level gauge on the installation assembly.

[0023] like Figures 1 to 4As shown, the dam water level gauge installation assembly of this embodiment includes a base 1. The base 1 has four mounting holes at its top corners for connection to a pre-embedded concrete foundation on the dam, allowing the base 1 to be stably installed on the dam. A bottom pipe 2 is fixedly connected to the top of the base 1. A top pipe 5 is provided at the top of the bottom pipe 2. A sleeve 7 is provided at the top of one side wall of the top pipe 5. A telescopic rod 11 is provided inside the sleeve 7. The outer diameter of the telescopic rod 11 matches the inner diameter of the sleeve 7, allowing the telescopic rod 11 to slide along the inner wall of the sleeve 7 under the action of an electric push rod 13, thereby realizing the movement of the sleeve 7. The flexible change in the length of the end allows for adjustment of the monitoring range of the water level gauge 12. A water level gauge 12 is installed at one end of the telescopic rod 11. The water level gauge 12 is a radar-type water level gauge, which detects the water level of the dam by transmitting and receiving high-frequency electromagnetic waves. It has high accuracy and good stability. A cover box 10 is fixedly connected to the end of the sleeve 7 away from the jacking pipe 5. The cover box 10 is used to provide all-around protection for the water level gauge 12, thereby extending its service life. A diagonal tie rod 9 is fixedly connected to the top of the sleeve 7. The purpose is to reinforce the end of the sleeve 7, thereby increasing its stability on the jacking pipe 5. A cover 6 is installed at the top of the other side wall of the jacking pipe 5. The cover 6 protects the internal electric push rod 13, preventing it from being easily disturbed by the external environment. The electric push rod 13 is installed inside the cover 6 and can be activated by the controller to achieve traction control of the telescopic rod 11. An insertion tube 14 is provided at the bottom of the jacking pipe 5. The outer diameter of the insertion tube 14 matches the inner diameter of the bottom pipe 2, allowing the insertion tube 14 to be smoothly inserted. The tube 5 is inserted into the bottom tube 2 and then rotates along the inside of the bottom tube 2, thereby realizing the horizontal rotation of the top tube 5 along the bottom tube 2. An internal gear ring 15 is provided at the bottom of the inner wall of the insertion tube 14. A spur gear 16 meshes with the inner wall of the internal gear ring 15. The spur gear 16 can mesh with the internal gear ring 15 to rotate, thereby realizing the horizontal rotation of the top tube 5 along the top of the bottom tube 2. A forward and reverse motor 17 is installed at the bottom of the inner side of the bottom tube 2. A controller is also connected to one side of the forward and reverse motor 17 to control the forward or reverse rotation of the forward and reverse motor 17, thereby facilitating the reset of the installation components after maintenance.

[0024] Specifically, ear plates 3 are fixedly connected to the top end of the bottom pipe 2 and the bottom end of the top pipe 5. Fastening bolts 4 are movably passed through both sides of the ear plates 3. Nuts are movably threaded at the bottom end of the fastening bolts 4. The function of the ear plates 3 is to increase the contact area between the top pipe 5 and the bottom pipe 2. The function of the fastening bolts 4 is to reinforce the connection between the top pipe 5 and the bottom pipe 2, thereby improving the stability of the connection between the top pipe 5 and the bottom pipe 2.

[0025] Furthermore, the top end of the insertion tube 14 is fixedly connected to the ear plate 3 at the bottom end of the top tube 5, and the insertion tube 14 is movably embedded in the bottom tube 2. When the top tube 5 rotates horizontally, the insertion tube 14 will rotate inside the bottom tube 2, so that the top tube 5 can maintain better stability when rotating horizontally.

[0026] Furthermore, a photovoltaic module 8 is installed at the top of the jacking pipe 5. The photovoltaic module 8 is electrically connected to the electric push rod 13 and the forward and reverse motor 17 through a fixed inverter. The function of the photovoltaic module 8 is to provide power to the electrical equipment on this installation component, thereby ensuring the normal use of this installation component.

[0027] Furthermore, the end of the telescopic rod 11 away from the water level gauge 12 is fixedly connected to the output end of the electric push rod 13. The telescopic rod 11 is slidably connected to the sleeve 7 through the electric push rod 13. Under the control of the controller, the electric push rod 13 can push the telescopic rod 11 to slide along the sleeve 7, thereby realizing the position change of the water level gauge 12 in the horizontal direction, which is beneficial for the water level gauge 12 to be protected by being retracted into the cover box 10 in strong wind weather.

[0028] Furthermore, the cover box 10 has openings on the front and bottom. The water level gauge 12 is movably connected to the cover box 10 via the telescopic rod 11. The function of the cover box 10 is to enclose the water level gauge 12, reduce the effect of strong wind on the water level gauge 12, and thus help the water level gauge 12 maintain a stable state in strong wind weather.

[0029] Furthermore, the output end of the reversible motor 17 is fixedly connected to the middle of the spur gear 16. The spur gear 16 is meshed with the internal gear ring 15 through the reversible motor 17. Under the drive of the reversible motor 17, the spur gear 16 can mesh with the internal gear ring 15 to rotate, so that the internal gear ring 15 drives the insertion tube 14 to rotate inside the bottom tube 2, so that the top tube 5 rotates horizontally along the top of the bottom tube 2, thereby facilitating the position change of the water level gauge 12.

[0030] The usage method of this embodiment is as follows: When using the installation component of this dam water level gauge 12, the base 1 needs to be connected to the pre-embedded concrete foundation on the dam through the installation hole, so that the base 1 is fixed on the dam. Then, the insertion tube 14 at the bottom end of the jacking pipe 5 can be vertically inserted into the top of the bottom pipe 2 by hoisting. When the ear plate 3 at the bottom end of the jacking pipe 5 is in contact with the ear plate 3 at the top end of the bottom pipe 2, the internal gear ring 15 in the insertion tube 14 will mesh with the spur gear 16. Then, the two ear plates 3 can be locked and connected using the fastening bolt 4. Then, the installation component is connected to the power output terminal of the photovoltaic module 8. When encountering strong winds, the electric push rod 13 will drive the telescopic rod 11 extending out of the sleeve 7 to retract into the sleeve 7 under the control of the controller. At this time, the water level gauge 12 at the end of the telescopic rod 11 will slide towards the cover box 10 until the water level gauge 12 slides into the cover box 10 and is covered. For protection, when the water level gauge 12 needs to be repaired, the fastening screws on the ear plate 3 need to be separated from the ear plate 3 first. Then, the forward and reverse motor 17 will rotate forward under the control of the controller, driving the spur gear 16 to mesh and rotate with the gear ring, so that the gear ring drives the insertion tube 14 to rotate inside the bottom tube 2, driving the top tube 5 to rotate along the top of the bottom tube 2, so that the sleeve 7 on the top tube 5 drives the water level gauge 12 to rotate from the water surface on one side of the dam to the ground on the other side of the dam. Then, the fastening bolt 4 is reinserted into the ear plate 3, so that the top tube 5 and the bottom tube 2 are fixed again. At this time, the water level gauge 12 can be repaired. After the repair of the water level gauge 12 is completed, the fastening bolt 4 is pulled out. Then, the forward and reverse motor 17 will rotate in the reverse direction under the action of the controller, so that the top tube 5 and the sleeve 7 are reset. Finally, the fastening bolt 4 is fixed back on the ear plate 3.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
