Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor for a water pump. Background Art

[0002] With the rapid development of industrial automation and intelligence, water pumps, as key equipment for fluid transportation, have become particularly important for operating status and performance monitoring. Water pump sensors are important tools for monitoring the operating status of water pumps. Their accuracy and reliability directly affect the safe operation and performance optimization of water pumps. However, traditional water pump sensors have some shortcomings in installation and protection, which limits their widespread promotion and use in practical applications.

[0003] First, in terms of installation, traditional sensors for water pumps usually require complicated installation steps and professional installation tools, which not only increases the installation cost, but also reduces the installation efficiency. In addition, due to the inconvenience of the installation location, the connection between the sensor and the water pump often poses a safety hazard and is prone to failure or damage. Secondly, in terms of protection, traditional sensors for water pumps usually lack sufficient protection measures and are easily affected by environmental factors such as temperature, humidity, corrosion, etc., which lead to sensor performance degradation or failure, which not only affects the service life of the sensor, but also increases maintenance costs.

[0004] In order to solve the above problems, we propose a sensor for a water pump, which can be easily installed, protect the sensor, not affect the normal use of the sensor, and improve its sealing during use. Utility Model Content

[0015] Compared with the prior art, the utility model provides a sensor for a water pump, which has the following beneficial effects:

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 A water pump sensor includes a base 1, a detection chamber 2 integrally formed with the base 1 is fixedly mounted on the top of the base 1, the interior of the detection chamber 2 is hollow, and a through hole 5 for detection is provided on the top of the detection chamber 2, a detachable mounting plate 3 is provided on the bottom of the base 1, and a sensor 4 for detecting pressure is fixedly mounted on the other side of the mounting plate 3, and also includes:

[0026] A detection component, which is arranged inside the detection chamber 2 and is used to detect the pressure of the external liquid;

[0027] The sealing component is arranged inside the detection chamber 2 and is used to seal the detection chamber 2 and the detection component.

[0028] Furthermore, mounting seats 6 for installation are fixedly installed on both sides of the bottom of the base 1. The bottom of the mounting seat 6 is set to an arc shape that fits the inner wall surface of the pipeline. The mounting seat 6 is fixedly installed on the inner wall surface of the pipeline by screws.

[0029] Furthermore, friction pads 7 are fixedly installed at the bottom of the two sets of mounting seats 6 to assist in their fixation. The arrangement of the mounting seats 6 and the friction pads 7 and the fixation by screws not only simplifies the installation steps but also ensures the stability of the sensor in the pipeline. At the same time, the mounting seats 6 and the friction pads 7 further enhance the convenience and stability of the installation and reduce the difficulty and cost of the installation.

[0030] Furthermore, the detection component includes a recessed tube 8, a reset spring 9 and a contact plate 10. The recessed tube 8 is slidably installed inside the through hole 5. The bottom of the recessed tube 8 is in contact with the top of the sensor 4. The contact plate 10 is fixedly installed on the inner wall surface of the detection chamber 2 and the outer wall surface of the recessed tube 8. A reset spring 9 for resetting is fixedly installed between the two groups of the contact plates 10. The detection component achieves direct contact with the external pressure by sliding, thereby ensuring accurate detection of the liquid pressure. The reset spring 9 can respond quickly and return to its original position when the liquid pressure changes, thereby improving the continuity and accuracy of the detection.

[0031] Furthermore, a sealing edge 11 for strengthening the seal is fixedly installed on the outer wall surface of the mounting plate 3, and a sealing sheet 12 extending outward is fixedly installed at the edge of the sealing edge 11 corresponding to the position inside the detection chamber 2. Through the setting of the sealing edge 11 and the sealing sheet 12, liquid leakage and external impurities are effectively prevented from entering, thereby ensuring the stable operation and long-term reliability of the sensor in harsh environments.

[0032] Furthermore, the sealing assembly includes an inner concave tube 13 and a sealing sleeve 14. The inner concave tube 13 is integrally installed on the top of the inner wall of the base 1 at a position corresponding to the concave tube 8, and the sealing sleeve 14 for strengthening the sealing is fixedly installed at the position where the inner concave tube 13 contacts the outer wall of the concave tube 8.

[0033] Furthermore, a plurality of sealing rings 15 for enhancing the sealing effect are equidistantly fixedly installed on one side of the sealing sleeve 14 in contact with the recessed tube 8. By setting the sealing assembly, when the recessed tube 8 slides inside the through hole 5 under the influence of pressure, liquid can be effectively prevented from penetrating through the gap between the recessed tube 8 and the through hole 5, thereby protecting the sensor from corrosion during long-term use, which is more convenient and practical.

[0034] When in use, the device is first fixedly installed as a whole inside the pipe to be measured. During installation, the contact between the mounting seat 6 and the inner wall of the pipe can be increased by setting the friction pad 7, thereby improving the stability effect after installation and preventing it from displacement. After installation, when water flows through the device, the internal pressure of the water flow will squeeze the concave tube 8 to slide inside the through hole 5, so that the bottom of the concave tube 8 applies pressure to the top of the sensor 4, so that the pressure inside the pipe is measured through the sensor 4, and when the concave tube 8 is compressed into the detection chamber 2, the concave tube 8 will be pushed out and reset through the cooperation between the reset spring 9 and the contact plate 10, and through the cooperation between the inner concave tube 13 and the sealing sleeve 14, when the concave tube 8 shrinks into the detection chamber 2, it can prevent the external water flow from entering the detection chamber 2, thereby corroding the internal sensor and affecting its service life. Through the mutual cooperation between the above structures, the device can protect the sensor while facilitating its installation, without affecting the normal use of the sensor, and improve its sealing during use, which is more convenient and practical.
