The function of constant temperature water tank stores after to be water through heating source be heated to uniform temperature, when natural temperature is cooled to this temperature when following, heating automatically.The constant temperature water tank that cable now carries out insulating resistance value and withstand voltage test usefulness mostly is a water tank, when cable is put into, not only damages other parts of water tank so easily, also not enough simultaneously energy-conserving and environment-protective.
The utility model content
For addressing the above problem, the purpose of the utility model is that a kind of energy-conserving and environment-protective are provided, can make that hot and cold water mixes rapidly be used for the constant temperature water tank of cable at the water insulation and pressure test.
For achieving the above object, the technical scheme of the utility model is:
A kind of constant temperature water tank that is used for cable at the water insulation and pressure test is by casing, be located at heating tube, temperature sensor, the case lid in the said casing and be located at the outer heating controller of said casing and form; Said heating tube and said temperature sensor are electrically connected with said heating controller respectively, and said case lid is located on the said casing; Said casing is divided into main water box and time water tank by a dividing plate, and is interconnected through a rising pipe and a water inlet pipe; Said water inlet pipe is communicated with said main water box bottom, and the centre is provided with a water pump; Said rising pipe is communicated with said main water box top.
Preferably, be provided with an operation valve in the middle of the said rising pipe.
Preferably, said heating tube is located in said water tank.
Preferably, said temperature sensor is located in the said main water box.
Adopt the beneficial effect of present technique scheme to be: through said casing is divided into main water box and time water tank by a dividing plate, and to be interconnected through a rising pipe and a water inlet pipe; Said water inlet pipe is communicated with said main water box bottom, and the centre is provided with a water pump; Said rising pipe is communicated with said main water box top; Make water temperature when main water box be cooled to design temperature when following; Water pump is squeezed into main water box with the hot water that heats in the inferior water tank from the bottom automatically, thereby has reached simple in structure, reasonable in design, hot and cold water is mixed and the purpose of energy-conserving and environment-protective rapidly.

Fig. 1 is a kind of structural representation that is used for cable at the constant temperature water tank of water insulation and pressure test of the utility model embodiment.
The numeral corresponding component title represented among the figure with letter:
1. No. 13. water tanks of casing 11. dividing plates, 12. main water box
2. heating tube 3. temperature sensors 4. case lids 5. heating controllers
6. rising pipe 7. water inlet pipes 8. water pumps 9. operation valves
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Embodiment.
As shown in Figure 1, a kind of constant temperature water tank that is used for cable at the water insulation and pressure test is by casing 1, be located at heating tube 2, temperature sensor 3, the case lid 4 in the said casing 1 and be located at said casing 1 outer heating controller 5 and form; Said heating tube 2 is electrically connected with said heating controller 5 respectively with said temperature sensor 3, and said case lid 4 is located on the said casing 1; Said casing 1 is divided into main water box 12 and time water tank 13 by a dividing plate 11, and is interconnected through a rising pipe 6 and a water inlet pipe 7; Said water inlet pipe 7 is communicated with said main water box 12 bottoms, and the centre is provided with a water pump 8; Said rising pipe 6 is communicated with said main water box 12 tops.Wherein, be provided with an operation valve 9 in the middle of the said rising pipe 6; Said heating tube 2 is located in said water tank 13; Said temperature sensor 3 is located in the said main water box 12.
Adopt a kind of cable that is used for of present technique scheme to be: as shown in Figure 1 in the principle of work of the constant temperature water tank of water insulation and pressure test; At first water is stored in main water box 12 and time water tank 13 after being heated to design temperature through heating tube 2; Cable under test is put into main water box 12,, detected by temperature sensor 3 when the water natural temperature in the main water box 12 is cooled to this temperature when following; Detection signal is transferred to heating controller 5; When operating personnel's low temperature on the panel of seeing heating controller 5 shows, open operation valve 9 the water part in the main water box 12 is flowed in time water tank 13, the water in 2 pairs water tanks 13 of heating controller 5 commander's heating tubes begin heating simultaneously; When water was heated to uniform temperature, water pump 8 was unlocked the hot water in the inferior water tank 13 is squeezed in the main water box 12.Because the mouth of pipe of water inlet pipe 7 is bottoms of being located at water main 12; Hot water is that the bottom from main water box 12 is driven into; Principle according to the density of water follows temperature to be inversely proportional to adds the heat hydraulic pressure from water inlet pipe 7, and the water at low temperature that is positioned at main water box 12 tops can be sunk rapidly and evenly mix from water inlet pipe hot water; When the water temperature in temperature sensor 3 detects main water box 12 reaches design temperature, again signal is transferred to heating controller 5 commander's heating tubes 2 and stops heating.So circulation can make the water in the main water box 12 remain at the design temperature state.
In addition, when cable under test need detect insulation values and withstand voltage under different water temperatures, only need on heating controller 5, to reset the temperature that needs and get final product, its course of work is the same, repeats no more at this.
The beneficial effect of present technique scheme is: through said casing 1 is divided into main water box 12 and time water tank 13 by a dividing plate 11, and be interconnected through a rising pipe 6 and a water inlet pipe 7; Said water inlet pipe 7 is communicated with said main water box 12 bottoms, and the centre is provided with a water pump 8; Said rising pipe 6 is communicated with said main water box 12 tops; Make water temperature when main water box 12 be cooled to design temperature when following; Water pump 8 is squeezed into main water box 12 with the hot water of heating in the inferior water tank 13 automatically from the bottom, thereby has reached simple in structure, reasonable in design, hot and cold water is mixed and the purpose of energy-conserving and environment-protective rapidly.
Above-described only is a kind of preferred implementation that is used for cable at the constant temperature water tank of water insulation and pressure test of the utility model; Should be understood that; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
