Description

Technical Field

[0001] This utility model relates to the field of deflector technology for water turbines, and in particular to a control device for deflectors of impulse water turbines. Background Technology

[0002] The deflector is a crucial component of an impulse turbine unit. Working in conjunction with nozzles, it controls the magnitude and direction of the water flow entering the turbine runner. When the deflector is open, the water flow impinges on the runner through the nozzles, providing kinetic energy. When the deflector is closed, the water flow from the nozzles is cut off. In the event of a malfunction in the nozzle control system, the deflector must close quickly and reliably to prevent the turbine speed from continuing to increase. The deflector is typically connected to an external controller. In existing technologies, prolonged operation of the controller generates internal heat, which can damage internal electrical components. While existing controllers incorporate cooling mechanisms, these mechanisms are inconvenient to install and remove.

[0003] Chinese utility model (CN 213540609 U) discloses a control device for a deflector of an impulse turbine, including a controller body. The front surface of the controller body is connected to a heat dissipation mechanism via a connector. The heat dissipation mechanism includes components such as a first mounting frame, a second mounting frame, heat sinks, a connecting rod, and a limiting frame. Its working principle is that the connecting rod engages with the connecting groove, the first mounting frame is connected to the second mounting frame, the connecting block engages with the connecting groove, and the limiting mechanism is conveniently set in the first mounting frame to engage the heat sinks between the two opposing limiting frames. The heat sinks absorb and dissipate the heat generated in the electrical components inside the controller body.

[0004] However, the heat dissipation mechanism within this control device consists of multiple separable components, resulting in numerous loose parts during disassembly and assembly, making the process inconvenient. Therefore, we proposed an impulse turbine deflector control device to address these issues. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a deflector control device for impulse turbines, which solves the problem that the heat dissipation mechanism of the existing control device has many parts, making disassembly and assembly inconvenient.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: An impulse turbine deflector control device includes a controller body, on which a heat-conducting plate is provided. The heat-conducting plate has several fins. A threaded post is fixedly installed at the upper end of the heat-conducting plate. A locking nut is threaded onto the threaded post. A movable strip is movably sleeved on the threaded post between the locking nut and the heat-conducting plate. A fixed post is fixedly installed at the lower end of the heat-conducting plate. A fixed strip is fixedly installed on the fixed post.

[0007] Furthermore, the movable strip and the fixed strip are both covered with an anti-slip rubber layer on the side that is close to each other.

[0008] Furthermore, several of the fins are perforated by water supply pipes, one end of which is connected to a fixing cover and the other end is connected to a water inlet.

[0009] Furthermore, the heat-conducting plate is made of copper, and the back of the heat-conducting plate is attached to the front of the controller body.

[0010] Furthermore, a thermally conductive silicone grease layer is coated between the heat-conducting plate and the controller body.

[0011] Furthermore, the water inlet end of the water inlet is equipped with a filter screen, and the water immersion depth of the water inlet end is less than the water immersion depth of the fixed cover.

[0012] Furthermore, a removable insulating layer is provided between the heat-conducting plate and the controller body.

[0013] Furthermore, the inner wall of the water pipe is provided with multiple guide vanes, all of which are conical cylindrical structures.

[0014] Furthermore, the water supply pipe includes a first connecting pipe, a second connecting pipe, and multiple heat-conducting pipes, which are connected in series and all penetrate the fins and are connected to the fins. The heat-conducting pipes are copper pipes. The ends of the heat-conducting pipes away from the fins are respectively connected to the first connecting pipe and the second connecting pipe. Both the first connecting pipe and the second connecting pipe are rubber pipes.

[0015] Furthermore, the outer shell of the controller body is coated with a graphene coating layer.

[0016] The beneficial effects of this utility model are as follows: the back of the heat-conducting plate is placed on the front of the controller body, so that the fixing strip is close to the lower end of the controller body. Then the movable strip is naturally lowered and adjusted to be close to the upper end of the controller body. At this time, the locking nut is rotated so that the locking nut moves down along the threaded post until the locking nut pushes the movable strip against it. The fixing strip and the movable strip clamp the controller body. The entire control device has a simple structure and is more convenient to disassemble and assemble. Attached Figure Description

[0021] Please refer to the attached document. Figures 1-5This application provides a control device for a deflector of an impulse turbine, including a controller body 1. A heat-conducting plate 2 is mounted on the controller body 1, and several fins 3 are provided on the heat-conducting plate 2. A threaded post 21 is fixedly installed at the upper end of the heat-conducting plate 2, and a locking nut 22 is threadedly connected to the threaded post 21. A movable strip 23 is movably fitted between the locking nut 22 and the heat-conducting plate 2 on the threaded post 21. A fixing post 24 is fixedly installed at the lower end of the heat-conducting plate 2, and a fixing strip 25 is fixedly installed on the fixing post 24. The back of the heat-conducting plate 2 is placed against the front of the controller body 1, so that the fixing strip 25 is pressed tightly against the lower end of the controller body 1. Then, the movable strip 23 is lowered naturally and adjusted to be close to the upper end of the controller body 1. At this time, the locking nut 22 is rotated, causing the locking nut 22 to move downwards along the threaded post 21 until the locking nut 22 pushes against the movable strip 23, and the fixing strip 25 and the movable strip 23 clamp the controller body 1. The entire control device of this utility model has a simple structure and is easier to assemble and disassemble. Since the back of the heat-conducting plate 2 is in close contact with the front of the controller body 1, the heat of the controller body 1 is conducted to the heat-conducting plate 2 and dissipated through several fins 3 on the heat-conducting plate 2, thereby reducing the temperature of the controller body 1.

[0022] For details, please refer to the appendix. Figures 1-3 In sections 23 and 25, an anti-slip rubber layer (not shown) is attached to the side of the movable strip 23 and the fixed strip 25 that are close to each other. The anti-slip rubber increases the friction between the movable strip 23, the fixed strip 25 and the controller body 1, which can more stably fix the heat-conducting plate 2 to the controller body 1.

[0023] For details, please refer to the appendix. Figures 1-3 A plurality of the fins 3 are penetrated by a water supply pipe 4. One end of the water supply pipe 4 is connected to a fixing cover 41, and the other end is connected to a water inlet 42. Low-temperature cooling water enters the water supply pipe 4 through the water inlet 42. As the water flows through the water supply pipe 4, it cools the fins 3 and the heat-conducting plate 2. After exchanging heat with the fins 3 and the heat-conducting plate 2, the cooling water is discharged through the fixing cover 41.

[0024] In order to allow water to flow into the water supply pipe 4 to cool the fins 3, in one possible embodiment, both the fixed cover 41 and the inlet end 42 of this invention extend underwater, and the opening direction of the fixed cover 41 is perpendicular to the water outlet direction of the impulse turbine. Specifically, the water outlet direction of the impulse turbine is defined as the tangential direction of the runner, that is, the flow direction in which the water flows out along the tangential of the outer edge of the runner after impacting the runner. When the impulse turbine discharges water, the flow velocity increases and the pressure decreases at the fixed cover 41. The hot water in the water supply pipe 4, which has been heated by heat exchange, flows towards the fixed cover 41. At the same time, the low-temperature water that has not yet undergone heat exchange enters the water supply pipe 4 through the inlet end 42, thereby forming a flow of cooling water in the water supply pipe 4, which can rapidly reduce the temperature of the fins 3 and the heat-conducting plate 2.

[0025] In order to allow water to flow into the water supply pipe 4 to cool the fins 3, in another possible embodiment, the water inlet 42 can be connected to an external water pump, and the pump can directly pump cold water into the water supply pipe 4. By connecting the water inlet 42 to an external water pump, when the impulse turbine stops running or the water flow rate in the water supply pipe 4 is insufficient, the pump can be started to draw external cooling water into the water supply pipe 4, ensuring continuous heat dissipation for the fins 3.

[0026] In order to allow water to flow into the water supply pipe 4 to cool the fins 3, in another possible embodiment, the water inlet 42 of the water supply pipe 4 can be directly connected to an external water supply line, which can also achieve effective heat dissipation for the heat-conducting plate 2 and the fins 3. The water supply line can be a tap water line or other line that can continuously supply water. The water supply line can be equipped with a control valve, which can be a manual valve or an electrically controlled valve.

[0027] Specifically, the heat-conducting plate 2 is made of copper, and its back side is attached to the front side of the controller body 1. By using a copper heat-conducting plate 2, heat from the controller body 1 can be quickly transferred to the heat-conducting plate 2.

[0028] Specifically, a thermal grease layer is coated between the heat-conducting plate 2 and the controller body 1. In use, thermal grease is applied to the front side of the controller body 1, and then the back of the heat-conducting plate 2 is placed against the front side of the controller body 1. The thermal grease fills the microscopic gaps between the heat-conducting plate 2 and the controller body 1, reducing interfacial thermal resistance through efficient heat conduction, thereby improving heat dissipation efficiency.

[0029] For details, please refer to the appendix. Figure 3 and 4 The water inlet end 42 is equipped with a filter screen 421, and the water immersion depth of the water inlet end 42 is less than the water immersion depth of the fixed cover 41. The filter screen 421 can block impurities in the water to prevent them from clogging the water supply pipe 4 and affecting its use.

[0030] Specifically, a removable insulating layer (not shown) is provided between the heat-conducting plate 2 and the controller body 1. This removable insulating layer provides electrical isolation between the heat-conducting plate 2 and the controller body 1 without affecting heat transfer between them. Preferably, the surface of the insulating layer is uniformly coated with a high-temperature resistant adhesive.

[0031] For details, please refer to the appendix. Figure 6The inner wall of the water supply pipe 4 is provided with multiple guide vanes 43, all of which are conical cylindrical structures. The guide vanes 43 optimize the internal structure of the water supply pipe 4 and can increase the resistance to backflow of water in the water supply pipe 4, thereby reducing the possibility of backflow of water in the water supply pipe 4.

[0032] For details, please refer to the appendix. Figures 1-3 The water supply pipe 4 includes a first connecting pipe 441, a second connecting pipe 442, and multiple heat-conducting pipes 443. These heat-conducting pipes 443 are connected in series and all penetrate the fins 3 and are welded to them. The heat-conducting pipes 443 are made of copper. The ends of the heat-conducting pipes 443 furthest from the fins 3 are connected to the first connecting pipe 441 and the second connecting pipe 442, respectively. Both the first connecting pipe 441 and the second connecting pipe 442 are rubber tubes. By using copper heat-conducting pipes, the heat-conducting pipes 443 can quickly conduct heat from the fins 3 and the heat-conducting plate 2. The rubber-made first connecting pipe 441 and second connecting pipe 442 are flexible and easy to install and arrange.

[0033] Specifically, the outer shell of the controller body 1 is coated with a graphene coating layer. This improves the durability and reliability of the device in harsh environments.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
