Description

Technical Field

[0001] This utility model relates to the field of dry pump operation safety detection technology, and specifically discloses a dry pump leakage detection system. Background Technology

[0002] To reduce vibration and noise, dry pumps are typically mounted on a perforated mounting plate with support feet at each of the four corners. The dry pump is then fixed to the mounting plate. Because dry pumps are usually installed in elevated locations, they receive little attention from personnel, and any abnormalities may go undetected. Liquid leakage is a common anomaly during dry pump operation. Possible leakage effects typically include: leakage from the pump's own cooling pipes (internal leakage within the pump body), leakage from the inlet valve, and leakage from liquids surrounding the pump.

[0003] Regarding the impact of liquid leaks, dry pumps themselves lack liquid contamination detection capabilities, typically relying on periodic manual inspections or the installation of leak detection sensors. However, manual inspections are insufficient to detect leaks promptly. In contrast, leak detection sensors automatically detect leaks, sending a signal to a processor upon detection, which then issues an alarm and notifies maintenance personnel. However, as mentioned above, due to the numerous potential leak locations, installing leak detection sensors at each location would undoubtedly increase detection costs. Furthermore, installing leak detection sensors may require modifications to the existing dry pump or its mounting structure, further increasing costs. Therefore, this application proposes a dry pump leak detection system that eliminates the need for modifications to the existing dry pump or its mounting structure. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide a dry pump leakage detection system that can detect leakage and does not require modification of the dry pump itself or the dry pump installation structure.

[0005] The objective of this utility model is achieved through the following technical solution: a dry pump leakage detection system, comprising:

[0006] A water receiving tray includes a narrow section and a wide section that are internally interconnected. The narrow section is placed below the dry pump mounting bracket and between the support legs on opposite sides of the dry pump mounting bracket, and is used to receive liquid leaked from inside the dry pump. The wide section is located outside the dry pump mounting bracket and below the dry pump inlet valve, and is used to receive liquid leaked from the dry pump inlet valve.

[0007] A leak detection sensor is installed on the water receiving tray and is used to detect whether there is a leak in the water receiving tray.

[0008] This invention uses a water collection tray to collect liquid leaking from inside the dry pump or from the dry pump's inlet valve, and automatically detects the leak using a leak detection sensor. This eliminates the need for manual inspections and the need to install multiple sensors at common leak locations, thus reducing costs.

[0009] Positioning platforms are formed on both sides of the connection between the narrow and wide sections, and the support legs abut against the two positioning platforms respectively; an insert plate is provided at the end of the narrow section away from the wide section, and the insert plate abuts against the side wall of the dry pump mounting frame to limit the dry pump mounting frame between the positioning platform and the insert plate.

[0010] This utility model uses a positioning platform and insert plate to fix the entire water receiving tray to the dry pump mounting frame, preventing the water receiving tray from shifting due to external forces and affecting the receiving of leaks. The installation and fixing of the entire water receiving tray does not require changing the dry pump itself or the original dry pump installation structure, nor does it require drilling holes or adding fixing mechanisms on the installation platform such as the overhead floor to fix the water receiving tray.

[0011] The narrow section has a surrounding plate on its end wall, forming a slot between the surrounding plate and the end wall of the narrow section. The insert plate is removably inserted into the slot. The detachable design of the insert plate facilitates the installation of the water tray below the dry pump mounting bracket.

[0012] The dry pump leakage detection system also includes a leakage detection rope, which is wrapped around the water collection tray and the dry pump mounting bracket. The leakage detection rope can detect whether liquid is flowing towards the dry pump from the area surrounding it.

[0013] The water collection tray is inclined internally, and the leak detection sensor is located at the lower end of the tray. The inclined bottom of the tray facilitates the collection of leaked liquid, enabling the leak detection sensor to detect leaks promptly.

[0014] The water receiving tray is provided with a drain outlet at its lower end, and a drain pipe is connected to the drain outlet so that the leaked liquid can be drained away through the drain outlet and the drain pipe.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] (1) This utility model collects and gathers the liquid leaking from inside the dry pump or the inlet valve of the dry pump through the water receiving tray, and automatically detects it through the leakage detection sensor. It does not require manual inspection or the installation of multiple sensors at common leakage points, thus reducing costs.

[0017] (2) The installation and fixing of the water receiving tray of this utility model does not require changing the dry pump itself and the original dry pump installation structure, nor does it require drilling holes or adding additional fixing mechanisms on the installation platform such as the overhead floor to fix the water receiving tray.

[0032] Example 1

[0033] like Figure 1As shown, this embodiment discloses a dry pump leakage detection system, which includes a water receiving tray 11 and a leakage detection sensor 3 disposed on the water receiving tray 11. The water receiving tray 11 is used to collect liquid leaking from inside the dry pump 7 or from the dry pump inlet valve 12, and the leakage detection sensor 3 is used to detect whether there is leakage inside the water receiving tray 11. The leakage detection sensor 3 is electrically connected to an external control system. When the leakage detection sensor 3 detects liquid in the water receiving tray 11, it indicates that there is leakage at one or more locations inside the dry pump 7, or that there is leakage at the dry pump inlet valve 12. At this time, the leakage detection sensor 3 sends a signal to the external control system, which then issues an alarm to maintenance personnel, enabling them to promptly go to the site to confirm the location of the leakage and perform repairs. The leakage detection sensor 3 can be implemented using an existing water immersion sensor.

[0034] like Figure 1 As shown, the water receiving tray 11 includes a narrow portion 1 and a wide portion 2 that are internally interconnected, and the narrow portion 1 and the wide portion 2 can be integrally formed. The width of the narrow portion 1 is smaller than the width of the wide portion 2, allowing the narrow portion 1 to be inserted between the support legs 9 on opposite sides of the dry pump mounting bracket 8. Figure 3 As shown, during installation, the narrow section 1 is placed below the dry pump mounting bracket 8 and between the support feet 9 on opposite sides of the dry pump mounting bracket 8. Since the dry pump 7 is fixedly mounted on the perforated plate of the dry pump mounting bracket 8, when leakage occurs at one or more locations inside the dry pump 7, the liquid falls into the narrow section 1. The wide section 2 extends to the outside of the dry pump mounting bracket 8 and is located below the dry pump inlet valve 12, as shown. Figure 3 As shown, when the dry pump inlet valve 12 leaks, the leaked liquid falls into the wide section 2.

[0035] Furthermore, the inner bottom of the water receiving tray 11 is inclined, and the leakage detection sensor 3 is located at the lower end inside the water receiving tray 11. Specifically, the inner bottom of the water receiving tray 11 gradually decreases from the narrow part 1 side to the wide part 2 side, and the leakage detection sensor 3 is located on the side wall of the wide part 2. By making the inner bottom of the water receiving tray 11 inclined, it is beneficial for leakage to collect, enabling the leakage detection sensor 3 to detect leakage in a timely manner.

[0036] The lower end of the water receiving tray 11 may also be provided with a drain outlet, and a drain pipe is connected to the drain outlet. That is, in this embodiment, a drain outlet is opened on the side wall of the wide part 2, and the outlet end of the drain pipe can extend to a position away from the dry pump 7 for collection, or the outlet end of the drain pipe can be inserted into the building's drain pipe. The leakage in the water receiving tray 11 can be drained away through the drain outlet and the drain pipe to prevent excessive leakage and overflow.

[0037] This invention uses a water receiving tray 11 to collect liquid leaking from inside the dry pump 7 or from the dry pump inlet valve 12, and automatically detects it using a leak detection sensor 3. This eliminates the need for manual inspection and multiple sensors at common leak locations, thus reducing costs.

[0038] Positioning platforms 4 are formed on both sides of the connection between the narrow section 1 and the wide section 2. That is, in this embodiment, the narrow section 1 and the wide section 2 are perpendicular to each other, making the water receiving tray 11 as a whole "T" shape. When the narrow section 1 is inserted between the support feet 9 on opposite sides of the dry pump mounting bracket 8, the two support feet 9 closest to the wide section 2 respectively abut against the two positioning platforms 4. Figure 3 As shown. Additionally, a insertion plate 6 is provided at the end of the narrow section 1 opposite to the wide section 2. The insertion plate 6 abuts against the side wall of the dry pump mounting bracket 8, thus confining the dry pump mounting bracket 8 between the positioning platform 4 and the insertion plate 6. Figure 4 As shown. In specific implementation, the width of the narrow part 1 can also be set to match the spacing between the support feet 9 on both sides of the dry pump mounting bracket 8. Therefore, when the narrow part 1 is inserted between the support feet 9 on both sides of the dry pump mounting bracket 8, the support feet 9 can abut against the side wall of the narrow part 1, so that the entire water receiving tray 11 is limited and fixed by the dry pump mounting bracket 8 in the front, back, left and right directions, preventing the water receiving tray 11 from shifting between the dry pump 7 and the dry pump mounting bracket 8 due to external forces, thus affecting the receiving of leakage. In actual installation, the dry pump 7 is fixedly installed on the dry pump mounting bracket 8, and the dry pump mounting bracket 8 is fixedly installed on the installation platform such as the overhead floor. In this embodiment, the water receiving tray 11 and the dry pump mounting bracket 8 are limited and fixed by the positioning platform 4, the insert plate 6 and the side wall of the narrow part 1. The installation and fixing of the entire water receiving tray 11 does not require changing the dry pump 7 itself and the original dry pump installation structure, nor does it require drilling holes or adding additional fixing mechanisms on the installation platform such as the overhead floor to fix the water receiving tray 11.

[0039] In addition, such as Figure 1 , 2 As shown, a U-shaped baffle 5 is provided on the end wall of the narrow section 1, thus forming a slot 10 between the baffle 5 and the end wall of the narrow section 1. The insert plate 6 can be removed and inserted into the slot 10. With the above structure, during installation, first remove the insert plate 6, insert the narrow section 1 between the support legs 9 on opposite sides of the dry pump mounting bracket 8, and finally insert the lower end of the insert plate 6 into the slot 10 from behind the dry pump 7. In this embodiment, the insert plate 6 is detachable, which facilitates the installation and removal of the water receiving tray 11.

[0040] Example 2

[0041] The dry pump leakage detection system in this embodiment, based on Embodiment 1, further includes a leakage detection rope 13. In practical use, the leakage detection rope 13 is fixed to the dry pump mounting platform (such as an elevated floor) by rope clips, and the leakage detection rope 13 surrounds the water receiving tray 11 and the dry pump mounting frame 8, such as... Figure 5 As shown; if several dry pumps are installed close to each other, the leak detection rope 13 can surround all the dry pumps together. In this embodiment, the leak detection rope 13 can detect whether there is liquid flowing towards the dry pump 7 from the area around the dry pump 7, so as to avoid affecting the dry pump. The liquid in the surrounding area may come from the drainage of surrounding equipment or the surrounding environment.

[0042] In practice, the leak detection rope 13 is also electrically connected to the external control system. When the leak detection rope 13 detects liquid, the signal is transmitted to the control system, and the control system will also issue an alarm to the maintenance personnel so that the maintenance personnel can go to deal with it in time.

[0043] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.
