Description

Technical Field

[0001] This utility model relates to the field of dual-color water level gauges, and in particular to a manual valve opening mechanism. Background Technology

[0002] Bicolor water level gauges are crucial devices for monitoring boiler drum water levels in thermal power plants. Under certain circumstances, the mica assembly of the bicolor water level gauge may leak. Furthermore, due to their original design and construction, most thermal power plants have relatively cramped spaces within the boiler drum compartment.

[0003] When a leak occurs in this space due to a dual-color water level gauge, workers need to cross the leak point to close the steam and water side primary valves of the steam drum, which greatly increases the risk of burns. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a manual door opening valve mechanism. By setting an additional wheel away from the steam and water handwheel, it can avoid being scalded by leakage at the leakage point of the dual-color water level gauge, making operation safer. Moreover, it is installed as an additional structure and will not damage the original structure, resulting in lower cost and greater safety and reliability.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a manual door opening mechanism, including a bracket and two sets of handwheel assemblies;

[0006] The bracket is positioned in front of the steam-water handwheel of the dual-color water level gauge;

[0007] Each handwheel assembly is provided with a set corresponding to the soda handwheel;

[0008] The handwheel assembly includes an additional handwheel, an extension rod, and a bearing housing;

[0009] The additional handwheel is located at the outer end of the extension rod, the inner end of the extension rod is connected to the soda handwheel, the bearing seat is fixed to the bracket, and the extension rod is mounted on the bearing seat via a bearing.

[0010] This design does not directly control the steam / water handwheel, but rather indirectly controls it by rotating an auxiliary wheel. The extension rod allows operators to move further away from the leak point on the dual-color water level gauge when operating the auxiliary wheel, preventing burns from close proximity. The bracket provides support for both the extension rod and the auxiliary wheel.

[0011] Preferably, the bracket includes a column and support bases. The column is vertically positioned on the ground, and two support bases are fixed to the column corresponding to two sets of handwheel assemblies. The bearing housing is fixed to the support bases. Using support bases makes it easier to fix the bearing housing.

[0012] Preferably, an isolation curtain is provided between the supports. This provides a larger protective area and further protects the workers.

[0013] Preferably, the extension rod is a telescopic rod, which allows for better adjustment of the distance to the soda handwheel.

[0014] Preferably, the extension rod includes a main rod and a telescopic sleeve. The telescopic sleeve is sleeved onto the front end of the extension rod. Adjustment holes are distributed on the side wall bearings of the extension rod, and pin holes are provided on the side wall of the telescopic sleeve. A pin passes through the pin holes to the adjustment holes. After the spacing is determined, the two can be locked by the pin engaging different pin holes.

[0015] Preferably, the inner end of the extension rod is provided with a connecting plate, and a plurality of connecting rods are fixed on the surface of the connecting plate. Each connecting rod passes through the spoke holes from the front of the soda handwheel to the rear, and the other end of each connecting rod is connected by a chuck. By utilizing the space between the spokes of the soda handwheel, the connecting rods can be inserted to more stably lock the extension rod relative to the soda handwheel.

[0016] Preferably, the connecting rod has threaded sections at both ends, and the two ends of the connecting rod are respectively connected to the connecting plate and the chuck with nuts. The threaded connection facilitates assembly and disassembly, and the connecting rod and chuck can more stably hook the spokes of the soda handwheel.

[0017] Preferably, the chuck includes several connecting segments, each with through holes at both ends. The through holes at the beginning and end of the connecting segments are connected in a ring structure. The end of the connecting rod passes through the through holes to connect adjacent connecting segments. By connecting several connecting segments end to end, the soda handwheel can be enclosed. Furthermore, the connection between the beginning and end of the connecting segments is achieved through the connecting rod, resulting in a more compact and reliable structure.

[0018] Preferably, the connecting segment is an arc segment. This allows for a better formation of a circle and a more secure connection.

[0019] The beneficial effects of this utility model are:

[0020] This solution, by setting an additional wheel away from the water handwheel, avoids burns from leaks at the dual-color water level gauge's leakage point, making operation safer. Furthermore, it is installed as an add-on structure and does not damage the original structure, resulting in lower costs and greater safety and reliability. Attached Figure Description

Detailed Implementation

[0026] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0027] Example 1

[0028] like Figure 1 As shown, the manual door opening mechanism includes a bracket 1 and two sets of handwheel assemblies 4. The bracket 1 is positioned in front of the steam-water handwheel 14 of the dual-color water level gauge. Each set of handwheel assemblies 4 is provided corresponding to the steam-water handwheel 14. Each handwheel assembly 4 includes an auxiliary handwheel 5, an extension rod 6, and a bearing seat 13. The auxiliary handwheel 5 is located at the outer end of the extension rod 6, and the inner end of the extension rod 6 is connected to the steam-water handwheel 14. The bearing seat 13 is fixed to the bracket 1, and the extension rod 6 is mounted on the bearing seat 13 via a bearing.

[0029] This design does not directly control the steam / water handwheel 14, but indirectly controls it by rotating the auxiliary wheel. Due to the presence of the extension rod 6, operators can move further away from the leak point of the dual-color water level gauge when operating the auxiliary wheel, avoiding burns from close proximity. The bracket 1 provides support for the extension rod 6 and the auxiliary wheel.

[0030] The bracket 1 includes a column 2 and a support base 3. The column 2 is vertically positioned on the ground. Two support bases 3 are fixed to the column 2, corresponding to two sets of handwheel assemblies 4. The bearing seat 13 is fixed to the support base 3. Using the support base 3 makes it easier to fix the bearing seat 13.

[0031] The extension rod 6 is a telescopic rod, which allows for better adjustment of the distance between it and the soda handwheel 14.

[0032] The extension rod 6 includes a main rod 10 and a telescopic sleeve 11. The telescopic sleeve 11 is sleeved onto the front end of the extension rod 6. Adjustment holes are distributed on the side wall bearings of the extension rod 6. A pin hole is provided on the side wall of the telescopic sleeve 11, and a pin 12 passes through the pin hole to the adjustment hole. After the spacing is determined, the two can be locked by the pin 12 engaging with different pin holes.

[0033] The inner end of the extension rod 6 is provided with a connecting plate 7, and a plurality of connecting rods 8 are fixed on the surface of the connecting plate 7. Each connecting rod 8 passes through the spoke holes from the front of the soda handwheel 14 to the rear, and the other end of each connecting rod 8 is connected by a chuck 9. By utilizing the space between the spokes of the soda handwheel 14, the connecting rods 8 can be inserted to more stably lock the extension rod 6 relative to the soda handwheel 14.

[0034] The connecting rod 8 has threaded sections at both ends, and the two ends of the connecting rod 8 are respectively connected to the connecting plate 7 and the chuck 9 with nuts. The threaded connection makes disassembly and assembly easier, and the connecting rod 8 and the chuck 9 can more stably hook the spokes of the soda handwheel 14.

[0035] Example 2

[0036] Combination Figure 2 and Figure 3 As shown, compared to Embodiment 1, this embodiment also includes the following differences: the chuck 9 includes several connecting segments, each connecting segment has through holes at both ends, and the through holes at the beginning and end of the connecting segments are connected in a ring structure. The end of the connecting rod 8 passes through the through holes to connect adjacent connecting segments. By connecting several connecting segments end to end, the soda handwheel 14 can be enclosed, and the connection between the beginning and end of the connecting segments is made more compact and reliable. An isolation curtain 15 is provided between the support bases 3, providing a larger protective area and further protecting the staff. Several hooks are provided on the upper and lower support bases 3 respectively, and the upper and lower edges of the isolation curtain 15 are respectively fixed by hanging rings and hooks.

[0037] The connecting segment is an arc segment. This allows it to better form a circle, resulting in a more secure connection.

[0038] The beneficial effects of this utility model are:

[0039] This solution, by setting an additional wheel away from the water handwheel 14, can avoid burns from leaks at the dual-color water level gauge leakage point, making operation safer. Moreover, it is installed as an additional structure and will not damage the original structure, resulting in lower cost and greater safety and reliability.
