Description

Technical Field

[0001] This utility model relates to the field of boiler technology, specifically to a boiler water-cooling device. Background Technology

[0002] Boiler water cooling equipment is an important part of the boiler furnace. It consists of multiple water-cooled tubes arranged in a row. Cooling water circulates inside the tubes to remove heat from the sides of the boiler and lower its temperature. The water-cooled tubes have fire-facing and fire-repellent sides. The fire-facing side has a higher heat load and temperature, making it prone to cracking and leakage. Leakage can cause uneven heating and cooling on the sides of the boiler, resulting in damage. It is necessary to shut off the water flow to the water-cooled tubes. Existing methods generally use a water flow meter to detect the flow rate and remotely control an electrically controlled water valve to close the water flow in the water-cooled tubes when the flow rate decreases. However, remote electrical control is unstable and cannot effectively guarantee the shut-off of the water flow inside the water-cooled tubes. Therefore, a boiler water cooling device is proposed.

[0025] like Figures 1 to 2As shown, a boiler water cooling device includes a water cooling pipe 1, which is a circular pipe. A fitting pipe 2 is provided on the side of the water cooling pipe 1 and the fitting pipe 2 is fixedly installed on the side of the water cooling pipe 1 by flange bolts. The fitting pipe 2 is a circular pipe. A detection component 3 for detecting water flow is provided inside the fitting pipe 2. An auxiliary component 4 for closing the water flow is provided inside the fitting pipe 2 at the position corresponding to the detection component 3.

[0026] Specifically, the detection component 3 can detect the water flow rate inside the water-cooling pipe 1, and when the water flow decreases, the auxiliary component 4 can be triggered to reduce the water flow. When the water flow rate decreases further, the auxiliary component 4 can be triggered to close the valve inside the fitting pipe 2, thus timely cutting off the water flow inside the water-cooling pipe 1.

[0027] like Figures 2-4 As shown, the detection component 3 includes a mounting block 301 disposed inside the fitting tube 2. The mounting block 301 is an annular block. Connecting blocks 302 are fixedly mounted circumferentially and at equal intervals on the side of the mounting block 301, and the connecting blocks 302 are fixedly mounted inside the fitting tube 2. The connecting blocks 302 are fan-shaped blocks. A detection rod 303 is movably mounted inside the mounting block 301. The detection rod 303 is a cylindrical rod with a threaded section on one side and a "T"-shaped cross-section. Blocking blocks 304 are fixedly mounted circumferentially and at equal intervals on the side of the detection rod 303, and the blocking blocks 304 are engaged between the connecting blocks 302. The blocking blocks 304 are arc-shaped blocks with a "L"-shaped cross-section. A sealing ring 305 is fixedly mounted on the upper side of the mounting block 301. The sealing ring 305 is movably sleeved on the side of the detection rod 303. The sealing ring 305 is a rubber ring. A linkage block 306 is threaded on the lower side of the detection rod 303. The linkage block 306 is a ring block with threads on the inner side. A support cylinder 307 is provided between the linkage block 306 and the mounting block 301. The support cylinder 307 is movably sleeved on the side of the detection rod 303. The support cylinder 307 is a spring steel cylinder with a continuous "W" shaped cross section. A detection block 308 is provided on the lower side of the mounting block 301. A battery block is provided on the side of the detection block 308 for power supply. The detection block 308 is a distance sensor (LQD-31NC). The detection block 308 can remotely feed back the signal to an external controller.

[0028] Specifically, when the water flows into the fitting pipe 2, the water pressure pushes the block 304 away from the position between the connecting blocks 302, allowing the water to flow into the water cooling pipe 1. Under a fixed water flow rate, the push on the detection rod 303 causes the linkage block 306 to deform the support cylinder 307. The detection block 308 can detect the distance change of the linkage block 306 and feed it back to the controller. The water flow rate can be calculated by the distance change of the linkage block 306, and the flow rate can be detected.

[0029] like Figure 3 , Figure 5 As shown, the auxiliary component 4 includes a movable block 401 threadedly installed inside the fitting tube 2. The movable block 401 is a circular block with equidistant fan-shaped grooves on its side and threads on its side. A limiting block 402 is fixedly installed on the inner side of the fitting tube 2, corresponding to the upper position of the movable block 401. The limiting block 402 is an annular block. A constraint groove 403 is provided on the lower side of the movable block 401. The constraint groove 403 is a circular groove with a convex cross-section. A mating block 404 is movably installed inside the constraint groove 403. The mating block 404 is a circular block with equidistant fan-shaped grooves on its side and an I-shaped cross-section. A linkage cylinder 405 is provided on the upper side of the movable block 401 and is located below the linkage block 306. The linkage cylinder 405 is a cylinder with a hollowed-out lower side. Guide grooves 406 are provided in a circumferential array equidistantly on the side of the linkage cylinder 405. 406 is a threaded arc-shaped groove. A connecting groove 407 is circumferentially arrayed and equidistantly opened on the inner wall of the constraint groove 403 corresponding to the guide groove 406, penetrating the movable block 401. The connecting groove 407 is an arc-shaped groove. A fixing rod 408 is fixedly installed circumferentially arrayed and equidistantly on the upper side of the constraint groove 403, and the fixing rod 408 extends through the connecting groove 407 to the guide groove 406. The fixing rod 408 is a rectangular rod. A guide rod 409 is fixedly installed on the side of the fixing rod 408 and is movably installed inside the guide groove 406. The guide rod 409 is a cylindrical rod. A support spring 410 is provided between the upper side of the movable block 401 and the inner side of the linkage cylinder 405. An electric push rod 411 is fixedly installed on the upper side of the movable block 401 and is located inside the linkage cylinder 405. A battery that can supply power is provided on the side of the electric push rod 411.

[0030] Specifically, when the fitting pipe 2 begins to supply water, the electric actuator 411 pushes the linkage cylinder 405 to squeeze the linkage block 306, causing the detection rod 303 to disengage from the position between the linkage block 304 and the connecting block 302. Simultaneously, the guide groove 406 drives the guide rod 409 to constrain the fixed rod 408 to slide within the connecting groove 407. The fixed rod 408 drives the mating block 404 to rotate. At this time, the mating block 404 and the movable block 401 are in a connected, valve-like position, and the support spring 410... The linkage cylinder 405 provides slight elastic support, and the water flow can push the detection component 3 to connect the accessory pipe 2 for use. Conversely, when water leaks from the side of the water-cooled pipe 1, the water flow inside the water-cooled pipe 1 decreases. The support cylinder 307 pushes the linkage block 306 to squeeze the linkage cylinder 405 to slowly reset, so that the mating block 404 and the movable block 401 are staggered, reducing the water supply. When the linkage cylinder 405 is fully reset, the fan-shaped grooves of the mating block 404 and the movable block 401 are staggered to close the valve, thus stopping the water flow inside the accessory pipe 2.

[0031] More specifically, when inspecting the fitting tube 2, remove the flange screws and take out the fitting tube 2. First, use a tool to remove the threaded movable block 401 from inside the fitting tube 2, and pull out components such as the linkage cylinder 405. Then, replace and maintain the electric push rod 411, battery, etc. Then, remove the threaded linkage block 306, and you can directly pour the detection rod 303 out of the fitting tube 2 to replace and maintain the detection block 308, battery, etc.

[0032] In summary: The detection component 3 can detect the water flow inside the water-cooling pipe 1, and can be used in conjunction with the downstream water flow measuring instrument for verification. The auxiliary component 4 can automatically trigger the valve opening state, which in turn triggers the detection component 3 to connect the water flow inside the fitting pipe 2. When the water flow decreases, the auxiliary component 4 can work with the detection component 3 to slowly reduce the water supply, and can ultimately achieve valve closure inside the fitting pipe 2, effectively cutting off the water flow inside the water-cooling pipe 1. The mechanical structure can effectively and stably ensure the timely and effective cutting off of the water flow inside the water-cooling pipe 1, avoiding the situation where the electric control valve cannot effectively and timely cut off the water flow inside the water-cooling pipe 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
