Specific embodiments
[0025] The following further describes the present utility model in detail with reference to embodiments:
[0026] The following further describes in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0027] Such as Figures 1 to 7As shown in the figure, a detection device for the inner tank of a water heater includes: a chassis 1 with a water tank 11, a support frame 2 is connected to the chassis 1, the support frame 2 is connected with a first lifting structure 3, the first lifting structure 3 is located above the water tank 11, the first lifting structure 3 is connected with a moving frame 4 that can move up and down relative to the support frame 2 following its movement, a detection station 41 for placing the inner tank 100 is provided on the moving frame 4, at least three connecting pipes 101 are provided on the inner tank 100, one of the three connecting pipes 101 is connected with a closing member 102 that can close the connecting pipe 101, an installation opening 103 is further provided at the front end of the inner tank 100, and the inner tank 100 is connected with a heating component 104 that can close the installation opening 103. A plurality of second lifting structures 5 are further connected to the moving frame 4, and a sealing cap 6 that can close the connecting pipe 101 following its up and down movement is connected to the plurality of second lifting structures 5. An air vent passage 61 is provided in the sealing cap 6, and an inflater that can inflate the inner tank 100 through the air vent passage 61 is connected to the other side of the sealing cap 6.
[0028] When it is necessary to perform an airtightness test on the inner tank 100, the heating component 104 is installed on the inner tank 100 from the installation opening 103, then the closing member 102 is installed on the connecting pipe 101 at the outermost end among the three connecting pipes 101, then the inner tank 100 is placed on the detection station 41 of the moving frame 4, so that the three connecting pipes 101 of the inner tank 100 face upward and face the sealing cap 6. Subsequently, the staff starts the second lifting structure 5, so that the second lifting structure 5 plugs the sealing cap 6 on the ports of the two connecting pipes 101. After the inflater is started, the gas enters the connecting pipe 101 along the air vent passage 61 and then flows into the inner tank 100. Then the first lifting structure 3 is started, and the first lifting structure 3 drives the moving frame 4 to move up and down relative to the support frame 2, so that the moving frame 4 enters the water tank 11 until the water surface submerges the inner tank 100. The staff judges the airtightness of the inner tank 100 by observing whether there are bubbles in the water tank 11. After the test is completed, the first lifting structure 3 is started again to move the support frame 2 out of the water tank 11, and then the second lifting structure 5 is started again. The second lifting structure 5 makes the sealing cap 6 separate from the inner tank 100, and the staff can then remove the inner tank 100 from the moving frame 4. Therefore, when using the detection device for the inner tank of the water heater of the present utility model, there is no need for the staff to manually connect or disassemble the ports of the connecting pipes 101 on the water tank 100, making the airtightness test operation of the water tank more convenient. Moreover, since the closing member 102 and the heating component 104 have been installed on the water tank 100, the airtightness of the heating component 104 will also be tested when testing the airtightness, reducing the number of tests and making the detection more convenient.
[0029] The inflator can be an air compressor for filling gas into the intake passage 411.
[0030] As Figure 1 shown, a fixing component 7 capable of cooperating with the second lifting structure 5 and the sealing cap 6 to fix the inner container 100 is provided on the moving frame 4. The fixing component 7 is used to fix the lower end of the inner container 100. During testing, the second lifting structure 5 presses down the sealing cap 6 so that the sealing cap 6 presses against the communicating pipe 101 and cooperates with the fixing component 7 to clamp the inner container 100 more firmly, avoiding the movement of the inner container 100.
[0031] As Figures 5 to 6 shown, the fixing component 7 includes a connection base 71 connected to the moving frame 4. Rotating members 72 capable of rotating relative to it are connected to the left and right ends of the connection base 71. A connection portion 722 that protrudes outward and contacts the inner container 100 is connected to the top surface 721 of the rotating member 72. The connection base 71 is used for support and is also convenient to be arranged on the moving frame 4. After the inner container 100 is placed on the connection portion 722, the rotating member 72 rotates so that the connection portion 722 fits with the inner container 100 more firmly.
[0032] As Figures 5 to 6 shown, a rotating seat 73 capable of rotating relative to both of them is provided between the end of the rotating member 72 and the connection base 71. A first rotating shaft 731 and a second rotating shaft 732 are arranged at intervals up and down on the rotating seat 73. The rotating seat 73 is rotationally connected to the connection base 71 through the first rotating shaft 731, and the rotating member 72 is rotationally connected to the rotating seat 73 around the second rotating shaft 732. The setting of the rotating seat 73 enables the rotating member 72 to have a larger rotation range. With this setting, the inner container 100 can be clamped more firmly.
[0033] As Figures 5 to 6 shown, the connection portion 722 is arranged in a cross shape. The cross-shaped structure can provide support points in multiple directions, enabling the connection portion 722 to clamp the inner container 100 more stably. The cross-shaped structure can adapt to inner containers 100 with different arcs, and the adaptation range is wider.
[0034] As Figures 5 to 6 shown, the connection base 71 is arranged in an arc shape. It is convenient to adapt to the inner container 100 and clamp it more firmly.
[0035] As Figure 1 shown, a clamping component 8 capable of clamping the moving frame 4 is further provided on the bottom frame 1. Connecting the moving frame 4 only through the second lifting structure 5 is not stable enough. In order to limit the moving position of the moving frame 4 and avoid the sliding of the moving frame 4, the clamping component 8 is provided to clamp the moving frame 4, making it safer.
[0036] AsFigure 1 As shown, the clamping assembly 8 includes two groups of mounting seats 81 arranged front and back on the chassis 1. Two mounting seats 81 in the same group are symmetrically arranged on the outer sides of the moving frames 4 left and right, and rollers 82 capable of cooperating for clamping are connected to each moving frame 4. The arrangement of the rollers 82 facilitates the movement of the moving frames 4 and also facilitates clamping the moving frames 4.
[0037] As Figure 7 shown, the cross-section of the sealing cap 6 gradually decreases from top to bottom. The sealing cap 6 is in a conical shape with a larger upper part and a smaller lower part, so that the sealing cap 6 seals the port of the water tank, improving the sealing effect.
[0038] As Figure 1 shown, the first lifting structure 3 and the second lifting structure 5 are linear cylinders. In some embodiments, since the second lifting structure 5 needs to be immersed in the water in the water tank 100, the second lifting structure 5 can be a hydraulic push rod, a cylinder, etc., so as to be able to work normally in water and avoid being affected by the humid environment.
[0039] The above has generally described the present invention in detail, but on the basis of the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
