Description

Technical Field

[0001] This utility model relates to a sensor, and more particularly to a temperature sensor. Background Technology

[0002] Temperature sensors used in industrial equipment, such as those used to measure the oil temperature of bearing bushes, require sealing to prevent oil leakage from the equipment through the sensor cable. Patent document CN205781434U discloses a leak-proof sealing structure for the cable and the equipment. To achieve a better sealing effect, the cable has a sleeve fitted on the outer wall of the section passing through the mounting bolt, retaining ball, and clamping bolt. The mounting bolt is directly threaded onto the equipment. Since different equipment has different lengths of temperature probes extending into the equipment, it is necessary to produce sensors with different sleeve lengths for different types of equipment, which reduces the product's versatility.

[0003] In addition, some devices are located at the bottom of the oil tank, where the pressure is relatively high, which places higher demands on the sealing of the sensor cables. Utility Model Content

[0004] To improve the versatility of temperature sensors, this invention provides a highly versatile temperature sensor.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A versatile temperature sensor includes a cable, a temperature probe disposed at one end of the cable, and a sleeve fitted over the outside of the cable. A sleeve is disposed at one end of the sleeve. The cable passes through the sleeve and the sleeve, allowing the temperature probe to exit from one end of the sleeve. The ends of the sleeve and the sleeve are sealed by a sealing assembly, forming a sealed cavity inside the sleeve and the sleeve.

[0007] The sleeve is provided with a bend, and after installation, the height of the sealing cavity inside the sleeve is higher than the liquid level of the medium inside the equipment.

[0008] Up to 12 cables can be provided. Each cable has a sealing component at the end that extends out of the sealing cavity to seal the cavity. Any excess cable can be wound and placed in the sealing cavity inside the sleeve.

[0009] The sealing assembly includes a connecting bolt, a clamping bolt, and a retaining ball. The connecting bolt is fixedly connected to the connection port at the end of the sleeve and the bushing. The clamping bolt is threadedly connected to the connecting bolt. The nut of the connecting bolt is provided with a constriction groove with a large opening at the top and a small opening at the bottom. After installation, one end of the retaining ball is inserted into the constriction groove, and the other end is pressed by the clamping bolt to seal the sealing cavity.

[0010] The two ends of the bead are provided with truncated cone guide surfaces.

[0011] The nut of the connecting bolt is provided with a threaded groove, the inner wall of the threaded groove is provided with an internal thread, and the side wall of the screw of the clamping bolt is provided with an external thread that mates with the internal thread. During installation, the screw of the clamping bolt is screwed into the threaded groove, and the bottom surface presses against the retaining bead.

[0012] The connecting bolt has a through hole for the cable to pass through, and the clamping bolt has a through hole for the cable to pass through.

[0013] The diameter of the sleeve is larger than the diameter of the tube.

[0014] The sleeve and the casing are integrally formed or sealed by welding.

[0015] The beneficial effects of this utility model are as follows: This utility model also provides a sleeve at one end of the sleeve encapsulating the cable. The sleeve can accommodate excess cable length. For different types of equipment, only the length of the cable extending from the sleeve needs to be adjusted, making the temperature sensor suitable for more different types of equipment. This eliminates the need to produce sensors with sleeves of different lengths for different equipment models, improving the sensor's versatility. The top of the sleeve is sealed by a sealing component, and the height of the sleeve is higher than the liquid level of the medium inside the equipment. By setting a sleeve higher than the liquid level of the medium and sealing both ends of the sleeve and the tube with sealing components, a sealed cavity is formed inside the sleeve and tube. Even if the sealing component of the tube fails after long-term use, because the height of the sleeve is higher than the liquid level of the medium, the medium will not flow back into the terminal box connected to the sensor, resulting in a better sealing effect.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0023] Reference Figures 1 to 4 A versatile temperature sensor includes a cable 1, a temperature probe 2 disposed at one end of the cable 1, and a sleeve 3 fitted over the outside of the cable 1. A sleeve 4 is disposed at one end of the sleeve 3, the diameter of the sleeve 4 being larger than the diameter of the sleeve 3. The sleeve 4 and the sleeve 3 are integrally formed or welded to form a sealed connection. The cable 1 passes through the sleeve 3 and the sleeve 4, allowing the temperature probe 2 to exit from one end of the sleeve 3. The ends of the sleeve 3 and the sleeve 4 are sealed by a sealing assembly 5, thereby sealing the interior of the sleeve 3 and the sleeve 4 to form a sealed cavity 40. A sleeve is also provided at one end of the sheath of the encapsulated cable. During installation, the cable length is designed to be longer than the sheath length to ensure that the temperature probe can be inserted into the equipment for temperature measurement. This utility model also provides a sleeve at one end of the sheath of the encapsulated cable. The sleeve can hold the excess cable length. For different types of equipment, only the length of the cable extending from the sleeve needs to be adjusted, so that the temperature sensor can be used for more different types of equipment. There is no need to produce sensors with different sleeve lengths for different models of equipment, thus improving the versatility of the sensor.

[0024] Example 1, as Figure 1 As shown, the sleeve is sealed to the lower end of the sleeve. The sleeve is a straight tube. At this time, the temperature probe extends into the equipment from one side to monitor the temperature.

[0025] Example 2, as Figure 2 As shown, the sleeve 3 has a bent section. After installation, the height of the inner sealing cavity 40 of the sleeve 4 is higher than the liquid level of the medium inside the equipment. With the sleeve having a bent section, the temperature probe is inserted from one side of the equipment and reaches into the high-temperature medium for temperature measurement. When installing this type of sensor, the sleeve needs to be installed at a high position so that the height of the inner sealing cavity is higher than the liquid level of the medium inside the equipment, preventing backflow and leakage from the top of the sleeve.

[0026] Up to 12 cables 1 can be provided. Each cable 1 has a sealing component 5 at the end that extends out of the sealing cavity 40 to seal the sealing cavity 40. Any excess portion of the cable 1 can be wound and placed in the sealing cavity 40 inside the sleeve 4.

[0027] In the third embodiment, the sleeve has a number of connection ports equal to the number of cables 1. Each cable is individually equipped with a sealing assembly consisting of a connecting bolt 50, a clamping bolt 51, and a retaining bead 52 for sealing connection.

[0028] During production, either a single connection port can be set on the sleeve, and a threading port corresponding to the number of cables can be set on the sealing component 5 of the sealing connection port, or a connection port equal to the number of cables 1 can be set on the sleeve, and a sealing component corresponding to the number of cables can be set to seal the end of each cable individually.

[0029] The sealing assembly 5 includes a connecting bolt 50, a clamping bolt 51, and a retaining ball 52. The connecting bolt 50 is fixedly connected to the connection port at the end of the sleeve 3 and the sleeve 4. The clamping bolt 51 is threadedly connected to the connecting bolt 50. The nut of the connecting bolt 50 is provided with a constriction groove 500 with a larger opening at the upper end and a smaller opening at the lower end. After installation, one end of the retaining ball 52 is inserted into the constriction groove 500, and the other end is pressed against the clamping bolt 51, so that the sealing cavity 40 is sealed. The two ends of the 2 are provided with truncated cone guide surfaces 520; the nut of the connecting bolt 50 is provided with a threaded groove 501, the inner wall of the threaded groove 501 is provided with an internal thread, and the side wall of the screw of the clamping bolt 51 is provided with an external thread that mates with the internal thread. During installation, the screw of the clamping bolt 51 is screwed into the threaded groove 501, and the bottom surface presses against the retaining bead 52; the connecting bolt 50 is provided with a through hole for the cable 1 to pass through, and the clamping bolt 51 is provided with a through hole for the cable 1 to pass through.

[0030] The ends of sleeve 3 and sleeve 4 are sealed by sealing components, and the height of the sleeve is higher than the liquid level of the medium inside the equipment. By setting a sleeve higher than the liquid level of the medium and sealing both ends of the sleeve and sleeve with sealing components, a sealed cavity is formed inside the sleeve and sleeve. Even if the sealing component of the sleeve fails after long-term use, the medium will not flow back into the terminal box connected to the sensor because the height of the sleeve is higher than the liquid level of the medium, resulting in a better sealing effect. The sealing component and sleeve form a double sealing structure, which makes the sealing effect of the temperature sensor better.
