Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a detachable liquid level measuring element bracket. Background Art

[0002] The top cover drainage system of a hydropower station plays a vital role in the safe operation of the station. Its primary function is to prevent flooding of the guide bearings and top cover by draining water, thereby ensuring stable operation of the hydropower station units. To achieve this, measuring components such as top cover level transmitters and float switches are widely used in top cover drainage control systems. They precisely control the start and stop of drainage pumps by monitoring rising water levels. However, since these measuring components and their mounting brackets are typically located within the guide cone, operating in an environment characterized by low light, high humidity, and extremely limited space, routine maintenance and replacement operations present significant challenges.

[0003] Traditional mounting brackets are usually fixed to the inner wall of the guide cone by welding. This non-disassembled form means that every time the liquid level measuring element is replaced or adjusted, the operator must enter the guide cone to perform the operation. This not only increases the difficulty and time cost of the operation, but also seriously threatens the safety and efficiency of the operator. Utility Model Content

[0004] The purpose of the utility model is to provide a detachable liquid level measuring element bracket, which aims to solve the problem that the installation method of the traditional mounting bracket easily leads to increased difficulty and time cost each time the liquid level measuring element is replaced or adjusted, and affects the safety and efficiency of the operator.

[0005] The utility model is achieved through the following technical solutions:

[0006] A detachable liquid level measuring element bracket comprises: a supporting mechanism, a positioning assembly, a first connecting rod and a second connecting rod, wherein the positioning assembly is detachably connected to the supporting mechanism, and the first connecting rod and the second connecting rod are both detachably connected to the positioning assembly.

[0007] Optionally, the supporting mechanism includes a base and a connecting seat, the connecting seat is detachably connected to the base, and the positioning assembly is detachably connected to the connecting seat.

[0008] Optionally, a first mounting hole is provided on the base.

[0009] Optionally, there are multiple first mounting holes, and the multiple first mounting holes are distributed in an array on the base.

[0010] Optionally, there are at least two connecting sockets, and the number of the positioning components corresponds to the number of the connecting sockets.

[0011] Optionally, a second mounting hole is provided on the connecting seat, and a third mounting hole corresponding to the second mounting hole is provided on the positioning assembly, and the second mounting hole and the third mounting hole are connected by bolts or pins.

[0012] Optionally, a slot is provided on the positioning assembly, and the slot is adapted to fit the second connecting rod.

[0013] Optionally, a limiting portion is provided at the connection portion between the second connecting rod and the clamping slot, and a diameter of the limiting portion is greater than a width of the clamping slot.

[0014] Optionally, the second connecting rod is a rod-shaped structure with a sleeve, and a limiting groove is provided on the sleeve, and the limiting groove is adapted to the measuring element to be installed.

[0015] Optionally, the first connecting rod is bolted to the positioning assembly.

[0016] The technical solution of the utility model has at least the following advantages and beneficial effects:

[0017] Significantly improved maintenance convenience: The detachable liquid level measuring element bracket makes replacement and maintenance of the liquid level measuring element extremely simple, greatly saving time and labor costs, while avoiding the risk of operators performing long and high-risk operations in cramped, humid, and poorly lit environments.

[0018] Enhanced operational safety: The original bracket is non-detachable, and personnel need to enter the guide cone when replacing components. Long-term operation in the guide cone poses safety hazards such as electric shock and drowning. The detachable bracket design of the utility model allows operators to save operating time, effectively reduce operational risks, and ensure the safety and health of operators.

[0019] Optimize structural design and improve stability: The entire bracket is made of stainless steel, which enhances the structural stability and corrosion resistance, enabling it to adapt to humid and harsh working environments; at the same time, through reasonable structural design, such as the detachable connection between the connecting seat and the base, and the positioning component and the connecting seat, the stability and reliability of the bracket are ensured.

[0020] Improve handling and installation efficiency: The bracket is made of lightweight materials and is designed as a detachable structure, making the handling and installation process simpler and faster, which not only reduces the labor intensity of operators but also improves work efficiency.

[0021] Taking into account both versatility and scalability: The design of the bracket fully considers the possibility of future technology upgrades and changes in measuring element specifications. By adopting standardized connection methods and adjustable mounting structures, the bracket can adapt to measuring elements of different specifications, providing strong support for the long-term and stable operation of the hydropower station top cover drainage system.

The base 1 is made of stainless steel to ensure corrosion resistance and sufficient strength. The shape of the base 1 can be square or round, and the specific shape is determined according to the actual situation of the inner wall of the guide cone. The connecting base 2 is also made of stainless steel and is designed as an "L" or "T" shaped structure to connect with the base 1 and the positioning assembly 3. The number of connecting bases 2 is determined according to actual needs, but there must be at least two, which are used to install the first connecting rod 4 and the second connecting rod 5, as well as other connectors for connecting measuring elements.
