Description

Technical Field

[0001] This utility model relates to the field of pump testing technology, specifically to a testing and inspection device for emergency rescue pumps. Background Technology

[0002] In emergencies such as floods, mine inrushes, and urban flooding, emergency rescue pumps can quickly and effectively remove accumulated water, provide clean drinking water to disaster-stricken areas, and transfer sewage and mud to designated treatment sites. After the emergency rescue pump is manufactured, its performance needs to be tested. During testing, the pump's inlet is connected to the outlet of the storage tank, and its outlet is connected to the return port of the storage tank. When the pump is turned on, the liquid in the storage tank is drawn out and then returned to the tank. After a set time, the pump is turned off, and its performance is tested. Existing storage tanks have a simple structure and cannot regulate the liquid temperature. However, in actual emergency rescue operations, liquid temperature may affect pump performance. Therefore, there is an urgent need for a testing device that can regulate the liquid temperature within the storage tank. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Example, refer to Figures 1-2 As an embodiment of this utility model, a testing and inspection device for an emergency rescue pump is proposed, including a heating tank 1 and a storage tank 2. The heating tank 1 is used to hold the heating medium; the storage tank 2 is set inside the heating tank 1 and has an outlet 3 and a return outlet 4. The outlet 3 is used to connect with the inlet of the emergency rescue pump, and the return outlet 4 is used to connect with the outlet of the emergency rescue pump.

[0035] In this embodiment, the storage tank 2 is used to store test media such as mud, and the heating tank 1 is a tank made of heat-insulating material to reduce heat loss. During testing, the inlet of the emergency rescue pump is connected to the outlet 3 of the storage tank 2, and the outlet of the emergency rescue pump is connected to the return port 4 of the storage tank 2. After the emergency rescue pump is turned on, the liquid in the storage tank 2 is drawn out by the emergency rescue pump and then returned to the storage tank 2. After the set time is reached, the emergency rescue pump is turned off, and its performance can be tested.

[0036] When the temperature of the liquid in the storage tank 2 needs to be raised, a heating medium of appropriate temperature is added to the heating tank 1. The heat from the heating medium is transferred to the liquid in the storage tank 2 through the wall, thus raising the liquid temperature. When the temperature of the liquid in the storage tank 2 needs to be lowered, a cooling medium of lower temperature, such as cold water or an ice-water mixture, can be added to the heating tank 1. The cooling medium absorbs the heat from the liquid in the storage tank 2, lowering the liquid temperature. This system can simulate liquid environments at different temperatures in actual emergency rescue operations, providing a basis for testing the reliability and stability of emergency rescue pumps at different temperatures, making the performance testing of emergency rescue pumps more realistic and reliable. It helps to study the impact of liquid temperature on the performance of emergency rescue pumps, providing a basis for the optimized design of emergency rescue pumps. The system has a simple structure and is easy to operate. The combined design of the heating tank 1 and the storage tank 2 makes the temperature control system easy to install and maintain. It can be used not only for performance testing of emergency rescue pumps but also for other testing applications requiring liquid temperature regulation.

[0037] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes a liquid outlet pipe 5, which is installed inside the heating tank 1 and located below the liquid surface. One end of the liquid outlet pipe 5 is connected to the liquid outlet 3, and the other end passes through the heating tank 1 to connect to the inlet of the emergency rescue pump. The connection between the liquid outlet pipe 5 and the emergency rescue pump is detachable. This ensures that the liquid remains in the heating environment of the heating tank 1 throughout its flow from the storage tank 2 to the emergency circulation pump, reducing heat exchange between the liquid and the outside air during the outflow process, resulting in a more stable liquid temperature and better maintaining the required temperature. The detachable connection facilitates the installation and removal of the liquid outlet pipe 5 from the emergency rescue pump, improving the flexibility and operability of the testing device. Different models of emergency rescue pumps can be quickly replaced for testing in different testing scenarios.

[0038] Furthermore, such as Figure 1As shown, it also includes a return pipe 6, which is installed inside the heating tank 1 and located below the liquid surface. One end of the return pipe 6 is connected to the return port 4, and the other end passes through the heating tank 1 to connect to the outlet of the emergency rescue pump. The return pipe 6 and the emergency rescue pump are detachably connected. This ensures that the liquid remains in the heating environment of the heating tank 1 during the process of returning to the storage tank 2 by the emergency circulation pump. This reduces heat exchange between the liquid and the outside air during the outflow process, making the liquid temperature more stable and thus better maintaining the required temperature. The detachable connection facilitates the installation and removal of the return pipe 6 and the emergency rescue pump, further improving the flexibility and operability of the testing device. Different models of emergency rescue pumps can be quickly replaced for testing in different testing scenarios.

[0039] Furthermore, such as Figure 2 As shown, it also includes a thermally conductive support rod 7, which is installed inside the heating tank 1 and located between the bottom of the liquid storage tank 2 and the heating tank 1. The upper end of the thermally conductive support rod 7 is below the liquid surface in the heating tank 1. By using the thermally conductive support rod 7 to lift the liquid storage tank 2, there is also a heating medium between the bottom of the liquid storage tank 2 and the heating tank 1, which can increase the heating area of ​​the liquid storage tank 2. Moreover, the heat of the heating medium in the heating tank can be quickly transferred to the liquid storage tank 2 through the thermally conductive support rod 7, so that the liquid in the liquid storage tank can reach the required temperature more quickly, thereby improving the heat transfer efficiency.

[0040] Furthermore, such as Figure 2 As shown, it also includes a positioning sleeve 8, which is located at the bottom of the liquid storage tank 2. The upper end of the thermally conductive support rod 7 is inserted into the positioning sleeve 8, and the lower end of the thermally conductive support rod 7 is threadedly connected to the heating tank 1. The positioning sleeve 8 increases the connection area between the thermally conductive support rod 7 and the liquid storage tank 2, making the installation of the liquid storage tank 2 more stable and reliable, ensuring that it will not loosen due to vibration or other factors during testing, and guaranteeing the stability of temperature regulation. The thermally conductive support rod 7 is threadedly connected to the heating tank 1. By adjusting the depth to which the thermally conductive support rod 7 is screwed into the heating tank 1, the vertical position of the liquid storage tank 2 can be changed. Furthermore, when not needed, the thermally conductive support rod 7 can be disassembled. The structure is simple, the operation is convenient and quick, saving time and effort. The diameter of the positioning sleeve 8 decreases linearly from bottom to top, facilitating the insertion of the positioning sleeve 8 and the thermally conductive support rod 7.

[0041] Furthermore, such as Figure 1 and Figure 2As shown, it also includes a heating and stirring shaft 9 and a rotary drive mechanism 10. The heating and stirring shaft 9 is rotatably mounted inside the liquid storage tank 2, and both ends of the heating and stirring shaft 9 extend outside the liquid storage tank 2. The rotary drive mechanism 10 is located outside the heating tank 1 and is connected to one end of the heating and stirring shaft 9 for transmission. The rotary drive mechanism 10 drives the heating and stirring shaft 9 to rotate, which not only stirs the liquid but also heats it, thereby making the liquid temperature more uniform and avoiding local overheating or underheating, thus improving the accuracy of temperature regulation.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes heat-conducting blades 11, which are arranged around the heating and stirring shaft 9 and inside the liquid storage tank 2. There are multiple heat-conducting blades 11, all of which are arranged along the length of the heating and stirring shaft 9. When the rotary drive mechanism 10 drives the heating and stirring shaft 9 to rotate, the heating and stirring shaft 9 drives the heat-conducting blades 11 to rotate synchronously, which can expand the stirring and heating range, further accelerate the rate of liquid heating or cooling, and make the liquid temperature more uniform.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer wall end face of the portion of the heating and stirring shaft 9 located inside the storage tank 2 is rectangular. A heat-conducting blade 11 is provided around each rectangular side of the heating and stirring shaft 9. The length of the heat-conducting blade 11 is greater than the length of the rectangular side located inside it. Each heat-conducting blade 11 has one end connected to a heat-conducting blade 11 located on one side of the heating and stirring shaft 9, and the other end extends to the outside of the heat-conducting blade 11 located on the other side of the heating and stirring shaft 9. For example... Figure 3 and Figure 4As shown, the lower end face of the heat-conducting blade 11 located on the right side of the heating and stirring shaft 9 is flush with the lower end face of the heating and stirring shaft 9. The upper end face of the heat-conducting blade 11 located on the right side of the heating and stirring shaft 9 extends above the upper end face of the heating and stirring shaft 9. The upper end face of the heat-conducting blade 11 located on the left side of the heating and stirring shaft 9 is flush with the upper end face of the heating and stirring shaft 9. The lower end face of the heat-conducting blade 11 located on the left side of the heating and stirring shaft 9 extends below the lower end face of the heating and stirring shaft 9. The right end of the heat-conducting blade 11 located above the heating and stirring shaft 9 is flush with the lower end face of the heating and stirring shaft 9. The heat-conducting blade 11 on the right side of the heating and stirring shaft 9 is connected to the middle part of the heat-conducting blade 11. The left end of the heat-conducting blade 11 above the heating and stirring shaft 9 extends to the left side of the left heat-conducting blade 11. The left end of the heat-conducting blade 11 below the heating and stirring shaft 9 is connected to the middle part of the heat-conducting blade 11 on the left side of the heating and stirring shaft 9. The right end of the heat-conducting blade 11 below the heating and stirring shaft 9 extends to the right side of the right heat-conducting blade 11. This allows the heat-conducting blade 11 to be reliably connected to the heating and stirring shaft 9 and to have a sufficiently large heat-conducting area.

[0044] Furthermore, such as Figure 2 As shown, it also includes a support frame 12 and a protective cover 13. The support frame 12 is disposed outside the heating tank 1, and the rotary drive mechanism 10 is disposed on the support frame 12. The protective cover 13 is disposed on the support frame 12 and located around the rotary drive mechanism 10. The protective cover 13 and the support frame 12 are detachably connected. The support frame 12 provides stable support for the rotary drive mechanism 10, ensuring that it will not shake or shift during operation. The protective cover 13 can protect the rotary drive mechanism 10 from the influence of the external environment, such as dust and moisture, and can extend the service life of the rotary drive mechanism 10. At the same time, the detachable connection facilitates the maintenance and repair of the rotary drive mechanism 10.

[0045] Furthermore, such as Figure 1 and Figure 2 As shown, the device also includes a water inlet pipe 14 and a pH adjustment valve 15. One end of the water inlet pipe 14 is connected to the inside of the storage tank 2, and the other end is located outside the storage tank 2. The outlet end of the pH adjustment valve 15 is connected to the middle of the water inlet pipe 14. By connecting the water inlet pipe 14 to the water delivery mechanism, water can be added to the storage tank 2 through the water inlet pipe 14, thereby adjusting the concentration of the liquid in the storage tank 2 to meet different detection requirements. By connecting the inlet end of the pH adjustment valve 15 to the pH adjustment agent delivery mechanism, acid or alkali solution can be added to the storage tank 2 through the pH adjustment valve 15, thereby adjusting the pH value of the liquid in the storage tank 2. This can simulate liquid environments with different acidity and alkalinity, further expanding the application range of the detection device. It can not only test the performance of emergency rescue pumps at different temperatures, but also provide a basis for its testing in liquids with different acidity and alkalinity.

[0046] Furthermore, such as Figure 2As shown, it also includes a heat-insulating sealing cover 16, which is located at the upper end of the heating tank 1. The heat-insulating sealing cover 16 is detachably connected to the heating tank 1. The heat-insulating sealing cover 16 can reduce heat loss in the heating tank 1, improve energy utilization efficiency, and also prevent external impurities from entering the heating tank 1, ensuring the cleanliness of the heating medium. The detachable connection facilitates cleaning and maintenance of the interior of the heating tank 1, as well as inspection and maintenance of the liquid storage tank 2 and other components.
