Description

Technical Field

[0001] The utility model relates to the technical field of training devices, in particular to a variable frequency constant pressure water supply system training device. Background Art

[0002] The variable frequency constant pressure water supply system is a water treatment system commonly used in modern buildings. With the development of variable frequency speed regulation technology and the increasing awareness of energy conservation, the energy-saving characteristics of the variable frequency constant pressure water supply system make it more and more widely used in residential areas, high-rise buildings, and fire water supply systems. However, the variable frequency constant pressure water supply system in actual application has a large structure, wide distribution, and is not intuitive, so it is not suitable to be used directly as a teaching experimental device. In order to meet the requirements of scientific research and teaching, there are many constant pressure water supply experimental equipment on the market, but the performance is mostly uneven and lacks the comprehensiveness and integration of the system.

[0003] A Chinese utility model patent with publication number CN208903464U discloses a variable frequency constant pressure water supply system training device, including an electrical control box and a water supply simulation system. The electrical control box is provided with a programmable PLC controller and a frequency converter, and the frequency converter is connected to the programmable PLC controller; the water supply simulation system includes a simulated water reservoir 1, a magnetic drive pump, a main water supply pipeline, a water supply branch pipeline, a pressure transmitter, a two-way flow switch, an electric regulating valve and a simulated water reservoir 2.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: the above-mentioned device controls the various components in the water supply simulation system through independent electrical control boxes. At present, the cover plate of the electrical control box and the electrical control box are mostly simply rotated. When the staff opens the cover plate, the cover plate of some electrical control boxes is easy to automatically reset under the action of gravity and inertia, which is easy to interfere with the staff's operation, and is not conducive to improving the staff's user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a variable frequency constant pressure water supply system training device.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a variable frequency constant pressure water supply system training device, including a water supply simulation system and an electrical control box for controlling the water supply simulation system, one side of the electrical control box is open, and a rotating groove is provided on the inner top wall of the electrical control box, a rotating rod is rotatably arranged in the rotating groove, a baffle for closing the electrical control box is provided on the rotating rod, and a limit assembly for limiting the baffle is provided on the rotating rod.

[0007] By adopting the above technical solution, when the staff needs to teach, the staff needs to teach students how to use the electrical control box to control the water supply simulation system. Then, after the explanation, the students need to independently complete the control process of the water supply simulation system. At this time, the staff needs to open the baffle and operate the electrical control box. At this time, the staff only needs to turn the baffle and then release the baffle to keep the baffle stable under the action of the limit assembly, without the staff manually applying a force to the baffle to keep it stable, thereby reducing the difficulty of operation for the staff.

[0008] Furthermore, a sliding groove is provided on the side wall of the rotating rod, an annular groove is provided on the inner wall of the rotating groove, the limiting assembly includes an annular plate slidably arranged in the annular groove, a plurality of limiting blocks distributed in a circumferential array on the inner wall of the annular plate, a limiting rod slidably arranged in the sliding groove, and a driving device arranged on the annular plate for driving the annular plate, a first inclined surface is provided on the side wall of the limiting block close to the axis of the annular plate, and a second inclined surface matching the first inclined surface is provided on the side wall of the limiting rod away from the axis of the rotating rod.

[0009] By adopting the above technical solution, when the staff opens the baffle, the rotating rod rotates with the baffle, so that the limit rod moves with the rotating rod and passes over multiple limit blocks. Then, when the baffle stops moving, the limit block adjacent to the limit rod blocks the limit rod, thereby keeping the rotating rod and the baffle stable, thereby reducing the probability of the baffle automatically resetting when the staff releases the baffle. Then, when the staff needs to reset the baffle, the staff only needs to turn on the driving device to make the annular plate and the limit block move upward synchronously, thereby separating the limit block from the limit rod. At this time, the staff only needs to rotate the baffle to make the baffle rotate at will.

[0010] Furthermore, a limit spring is fixed on the side wall of the limit rod, and the other end of the limit spring is fixed on the inner wall of the slide groove.

[0011] By adopting the above technical solution, when the baffle is opened, the limit rod moves with the rotating rod and passes over multiple limit blocks. At this time, the limit rod reciprocates under the action of the limit spring. The limit spring reduces the probability of the limit rod being stuck, thereby improving the stability of the device.

[0012] Furthermore, the driving device includes an electromagnet arranged on the top wall of the annular groove and an iron sheet arranged on the upper surface of the annular plate.

[0013] By adopting the above technical solution, when the staff needs to move the annular plate upwards, the staff only needs to energize the electromagnet to make the electromagnet adsorb the iron sheet, so that the annular plate and the limit block move upward synchronously, thereby reducing the operating difficulty of the staff.

[0014] Furthermore, a handle is provided on the side wall of the baffle to reduce the difficulty of the staff in driving the baffle.

[0015] Furthermore, a control switch is provided on the side wall of the handle, and the control switch is electrically connected to the electromagnet.

[0016] By adopting the above technical solution, when the staff needs to energize the electromagnet, the staff only needs to press the control switch while pulling the handle to energize the electromagnet. When the staff releases the control switch, the electromagnet is de-energized and separated from the iron sheet after a period of time.

[0017] Furthermore, a limiting groove is provided on the inner wall of the annular groove, a fixing block is slidably arranged in the limiting groove, and the fixing block and the annular plate are fixed to each other.

[0018] By adopting the above technical solution, the stability of the annular plate is improved, and the probability of the annular plate getting stuck is reduced, which is beneficial to improving the user experience of the staff.

[0019] Furthermore, an observation window for observing the working conditions of the equipment in the electrical control box is provided on the side wall of the baffle.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to teach, the staff needs to teach students how to use the electrical control box to control the water supply simulation system. Then, when the explanation is over, the students need to independently complete the control process of the water supply simulation system. At this time, the staff needs to open the baffle and operate the electrical control box. At this time, the staff only needs to turn the baffle and then release the baffle to keep the baffle stable under the action of the limit assembly. There is no need for the staff to manually apply force to the baffle to keep it stable, thereby reducing the difficulty of operation for the staff;

[0022] 2. In the present application, when the staff opens the baffle, the rotating rod rotates with the baffle, so that the limit rod moves with the rotating rod and passes over multiple limit blocks. Then, when the baffle stops moving, the limit block adjacent to the limit rod blocks the limit rod, thereby keeping the rotating rod and the baffle stable, thereby reducing the probability of the baffle automatically resetting when the staff releases the baffle. Then, when the staff needs to reset the baffle, the staff only needs to turn on the drive device to make the annular plate and the limit block move upward synchronously, thereby separating the limit block and the limit rod from each other. At this time, the staff only needs to rotate the baffle to make the baffle rotate at will;

[0023] 3. In this application, when the staff needs to energize the electromagnet, the staff only needs to press the control switch while pulling the handle to energize the electromagnet. When the staff releases the control switch, the electromagnet is de-energized and separated from the iron sheet after a period of time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-4 As shown, the embodiment of the present application discloses a variable frequency constant pressure water supply system training device, including a water supply simulation system 1, an electrical control box 11, a rotating rod 21, a baffle 3, a limit assembly 4, a limit spring 6, a handle 7, a control switch 71 and a fixed block 81. The electrical control box 11 is used to control the water supply simulation system 1, and one side of the electrical control box 11 is open. A rotating groove 2 is provided on the inner top wall of the electrical control box 11, and the rotating rod 21 is a round rod-shaped structure, and the rotating rod 21 is rotatably arranged in the rotating groove 2. The baffle 3 is a plate-shaped structure, and the baffle 3 is arranged on the rotating rod 21, and is used to close the electrical control box 11.

[0031] A sliding groove 31 is provided on the side wall of the rotating rod 21, and an annular groove 32 is provided on the inner wall of the rotating groove 2. The limiting assembly 4 is arranged on the rotating rod 21, and is used to limit the baffle 3. The limiting assembly 4 includes an annular plate 41, a limiting block 42, a limiting rod 43 and a driving device 5. The annular plate 41 is a plate-shaped structure with a circular ring cross section, and the annular plate 41 is slidably arranged in the annular groove 32. The limiting block 42 is a block-shaped structure, and a plurality of limiting blocks 42 are provided and distributed in a circumferential array on the inner wall of the annular plate 41, and a first inclined surface 44 is provided on the side wall of the limiting block 42 close to the axis of the annular plate 41. The limiting rod 43 is a rectangular rod-shaped structure, and the limiting rod 43 is slidably arranged in the sliding groove 31, and a second inclined surface 45 matching the first inclined surface 44 is provided on the side wall of the limiting rod 43 away from the axis of the rotating rod 21.

[0032] When the staff opens the baffle 3, the rotating rod 21 rotates with the baffle 3, so that the limit rod 43 moves with the rotating rod 21 and passes over a plurality of limit blocks 42. Then, when the baffle 3 stops moving, the limit blocks 42 adjacent to the limit rod 43 block the limit rod 43, thereby keeping the rotating rod 21 and the baffle 3 stable, thereby reducing the probability of the baffle 3 automatically resetting when the staff releases the baffle 3. Then, when the staff needs to reset the baffle 3, the staff only needs to turn on the driving device 5, so that the annular plate 41 and the limit blocks 42 can move upward synchronously, thereby separating the limit blocks 42 from the limit rod 43. At this time, the staff only needs to rotate the baffle 3 to make the baffle 3 rotate at will.

[0033] One end of the limit spring 6 is fixed to the side wall of the limit rod 43, and the other end of the limit spring 6 is fixed to the inner wall of the slide slot 31. When the baffle 3 is opened, the limit rod 43 moves with the rotating rod 21 and passes over a plurality of limit blocks 42. At this time, the limit rod 43 reciprocates under the action of the limit spring 6, and the limit spring 6 reduces the probability of the limit rod 43 being stuck, thereby improving the stability of the device.

[0034] The driving device 5 is arranged on the annular plate 41 and is used to drive the annular plate 41. The driving device 5 includes an electromagnet 51 and an iron sheet 52. The electromagnet 51 is arranged on the inner top wall of the annular groove 32. The iron sheet 52 is a sheet-like structure and is arranged on the upper surface of the annular plate 41. When the staff needs to move the annular plate 41 upward, the staff only needs to energize the electromagnet 51, so that the electromagnet 51 can adsorb the iron sheet 52, so that the annular plate 41 and the limit block 42 move upward synchronously, thereby reducing the difficulty of operation for the staff.

[0035] In order to reduce the difficulty for the staff to drive the baffle 3 , a handle 7 is provided on the side wall of the baffle 3 .

[0036] The control switch 71 is disposed on the side wall of the handle 7, and the control switch 71 is electrically connected to the electromagnet 51. When the staff needs to energize the electromagnet 51, the staff only needs to press the control switch 71 while pulling the handle 7 to energize the electromagnet 51. When the staff releases the control switch 71, the electromagnet 51 is de-energized and separated from the iron sheet 52 after a period of time.

[0037] A limiting groove 8 is provided on the inner wall of the annular groove 32, and a fixing block 81 is a rectangular block structure. The fixing block 81 is slidably disposed in the limiting groove 8, and the fixing block 81 is fixed to the annular plate 41. The fixing block 81 improves the stability of the annular plate 41 and reduces the probability of the annular plate 41 getting stuck, thereby improving the user experience of the staff.

[0038] In order to reduce the difficulty for the staff to judge the working status of the electrical control box 11 , an observation window 9 for observing the working status of the equipment in the electrical control box 11 is provided on the side wall of the baffle 3 .

[0039] The use principle of a variable frequency constant pressure water supply system training device in this embodiment is: when the staff needs to teach, the staff needs to teach the students how to use the electrical control box 11 to control the water supply simulation system 1. Then, when the explanation is over, the students need to independently complete the control process of the water supply simulation system 1. At this time, the staff needs to open the baffle 3 and operate the electrical control box 11. At this time, the staff only needs to turn the baffle 3 and then release the baffle 3, so that the baffle 3 can remain stable under the action of the limit assembly 4, and the staff does not need to manually apply a force to the baffle 3 to keep it stable, thereby reducing the difficulty of operation for the staff.
