Description

Technical Field

[0001] This application relates to the field of cable testing technology, and in particular to a water resistance testing device for heat tracing cables. Background Technology

[0002] During the production of heat tracing cables, water resistance testing is a crucial step in ensuring product quality and reliability. To ensure the cables can effectively resist water intrusion during actual use and prevent cable failure or performance degradation due to humid environments, rigorous water resistance testing is essential. This testing typically involves a 24-hour cycle of energization and water ingress / drainage. The process begins by immersing the cable in water, ensuring the water evenly covers the outer layer. Then, the power is turned on, simulating the environmental conditions the cable might encounter in real-world use. Simultaneously, continuous water ingress and drainage cycles simulate moisture penetration in a humid environment, observing whether the cable can maintain its stable electrical performance.

[0003] Therefore, we need a water resistance testing device for heat tracing cables that can solve the problem of how to automatically and continuously test the water resistance of heat tracing cables. Utility Model Content

[0004] The purpose of this application is to provide a water resistance testing device for heat tracing cables, which can solve the problem of how to automatically and continuously test the water resistance of heat tracing cables.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solution: a water resistance testing device for a heat tracing cable, comprising: a bracket, the bracket being a square frame, with connecting plates at the four corners of the top of the bracket; an upper water tank, the upper water tank being disposed on the top of the bracket and connected to the bracket via connecting plates, the upper water tank having a receiving layer and an electrical layer, the receiving layer having an opening at the top and multiple protrusions at the bottom, the receiving layer having an inlet and an outlet, the electrical layer having a power connection component for energizing the heat tracing cable; a lower water tank, the lower water tank being disposed below the bracket, the lower water tank having an opening at the top and two connection ports on one side of the lower water tank; a water pump, the water pump being disposed on one side of the lower water tank, one end of the water pump being connected to the connection port and the other end being connected to the inlet; a drain pipe, one end of the drain pipe being connected to the outlet and the other end being connected to the connection port; and a water level detection device, the water level detection device being disposed inside the upper water tank for detecting the water level in the upper water tank.

[0006] In the above technical solution, this embodiment places the heat tracing sample, including the integral components, into the receiving layer of the upper water tank. For heat tracing pads or heat tracing plates, units with cold-end leads should be used. Water is then pumped from the lower water tank into the upper water tank, completely immersing the sample. At this point, water injection is stopped, and the heat tracing cable inside the heat tracing device is energized. Drainage begins by opening the drain valve. Since the upper and lower water tanks are stacked, the water in the upper tank automatically drains into the lower water tank under gravity. The total time from the start of water injection to complete drainage should not exceed 4.5 minutes but not less than 2.5 minutes. After the water is drained, the heat tracing device should continue to be energized for at least 30 seconds. Then, the energization of the heat tracing device is stopped, and the next cycle of water injection begins. The test should continue for 24 hours. This solves the problem of how to automatically and continuously test the water resistance of the heat tracing cable, achieving the effect of automatically and continuously testing the water resistance of the heat tracing cable.

[0007] Furthermore, according to an embodiment of this application, a caster wheel is provided at the bottom of the bracket.

[0008] Furthermore, according to an embodiment of this application, the connecting plate is square and has four threads, which are used to connect it to the upper water tank via screws.

[0010] Furthermore, according to an embodiment of this application, a partition is provided between the containment layer and the power layer for separation.

[0011] Furthermore, according to an embodiment of this application, the lower water tank is square, the lower water tank is located on the right side of the bracket, and the connection ports are all located at the lower end of the lower water tank.

[0012] Furthermore, according to an embodiment of this application, valves are provided at both ends of the water pump, and the water pump actively draws water.

[0013] Furthermore, according to an embodiment of this application, a valve is provided at the lower end of the outlet to control the opening and closing of the drain pipe, which is used for passive drainage.

[0014] Furthermore, according to an embodiment of this application, the bracket, the upper water tank, and the lower water tank are connected by welding.

[0015] Furthermore, according to the embodiments of this application, the welding of the upper water tank and the lower water tank is guaranteed to be flat, without defects, without leakage, and to ensure sealing.

[0016] Compared with existing technologies, this application has the following advantages: This application employs a water resistance testing device for heat tracing cables. The heat tracing sample, comprising the integral components, is placed in the upper water tank's containment layer. For heat tracing pads or plates, units with cold-end leads should be used. Water is then pumped from the lower tank into the upper tank, completely immersing the sample. At this point, water injection is stopped, and the heat tracing cable is energized. Drainage begins by opening the drain valve. Since the upper and lower tanks are stacked, water in the upper tank automatically drains into the lower tank under gravity. The entire time from the start of water injection to complete drainage is no more than 4.5 minutes but no less than 2.5 minutes. After drainage, the heat tracing cable should continue to be energized for at least 30 seconds. Then, the energization is stopped, and the next water injection cycle begins.

[0031] Example 1:

[0032] like Figure 1-4As shown, this application discloses a water resistance testing device for heat tracing cables, comprising: a bracket 1, which is a square frame with connecting plates at the four corners of its top; and an upper water tank 2, which is disposed on top of the bracket 1 and connected to the bracket 1 via connecting plates. The upper water tank 2 contains a receiving layer 21 and a power layer 22. The receiving layer 21 has an opening at its top and multiple protrusions 211 at its bottom. The receiving layer 21 contains an inlet and an outlet. The power layer 22 contains a power connection component 221. Component 221 is used to energize the heat tracing cable; lower water tank 3 is located below the bracket 1, with an opening at the top and two connection ports on one side; water pump 4 is located on one side of the lower water tank 3, with one end connected to the connection port and the other end connected to the water inlet; drain pipe 5 is connected at one end to the water outlet and the other end to the connection port; water level detection device 6 is located inside the upper water tank 2 and is used to detect the water level in the upper water tank 2.

[0033] The bracket 1 is equipped with casters at the bottom. The connecting plate is square and has four threads, which are used to connect it to the upper water tank 2 via screws.

[0034] The power supply layer 22 is located on the left side of the upper water tank 2. A power inlet is located below the power supply layer 22 to provide power. A circular hole is located above the power supply layer 22. A partition separates the housing layer 21 from the power supply layer 22.

[0035] The lower water tank 3 is square and is located on the right side of the bracket 1. All connection ports are located at the lower end of the lower water tank 3. The bracket 1, upper water tank 2, and lower water tank 3 are connected by welding. The welding of the upper water tank 2 and lower water tank 3 is ensured to be flat, without defects, leak-proof, and airtight.

[0036] The water pump 4 is equipped with valves 51 at both ends, and the water pump 4 actively draws water. The lower end of the outlet is equipped with valve 51 to control the opening and closing of the drain pipe 5, which is used for passive drainage.

[0037] The water level detection device 6 is located on one side of the power layer 22 and is separated from the power layer 22 by a partition. The other side of the water level detection device 6 is close to the storage layer 21 and is separated from the storage layer 21 by a perforated plate, so that the water level detection device 6 can detect the water level of the storage layer 21.

[0038] During testing, the heat tracing sample, including the integral components, is typically placed in the receiving layer 21 of the upper water tank 2. For heat tracing pads or plates, units with cold-end leads should be used. Water from the lower water tank 3 is then pumped into the upper water tank 2 using the water pump 4. The upper limit of the water level is detected by the water level detection device 6, and the sample is fully immersed in water. At this point, water injection is stopped, and the heat tracing cable inside the heat tracing is energized through the power connection component 221. Then, drainage begins by opening the valve 51 of the drain pipe 5. Since the upper water tank 2 and the lower water tank 3 are stacked, the water in the upper water tank 2 automatically drains into the lower water tank 3 under gravity. The total time from the start of water injection to complete drainage should not exceed 4.5 minutes but should not be less than 2.5 minutes. After the water is drained, the heat tracing should continue to be energized for at least 30 seconds. Then, the power to the heat tracing is stopped, and the next cycle of water injection begins. After the heat tracing equipment's connectors are immersed in water, it should be checked to confirm that no water has seeped in, and the test should last for 24 hours. After all tests are completed, the next steps of dielectric strength test and insulation resistance test can be carried out.
