Description

Technical Field

[0001] This invention relates to the field of pressure sensor technology, and in particular to a pressure sensor for detecting liquids. Background Technology

[0002] A pressure sensor is a device that senses pressure signals and converts them into a usable electrical output signal according to a certain rule. Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit; liquid pressure sensors are a type of pressure sensor.

[0003] However, it still has the following drawbacks in practical use:

[0004] Existing liquid pressure sensors require the installation of multiple sensors to detect the pressure of liquids in pipelines within a network. This makes it difficult to locate and repair a damaged sensor in a timely manner.

[0005] Therefore, a new pressure sensor for detecting liquids is proposed to solve the above problems. Summary of the Invention

[0006] 1. Technical problems to be solved

[0007] The purpose of this invention is to provide a pressure sensor for detecting liquids. By adding a locator to each liquid pressure sensor body and setting a buzzer, the sensor can quickly locate the liquid after its approximate position is determined by the sound generated, thereby solving the problems mentioned in the background art.

[0008] 2. Technical Solution

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0010] This invention relates to a pressure sensor for detecting liquids, comprising:

[0011] Liquid pressure sensor body;

[0012] The fault location unit includes a bracket connected to the middle of the outer surface of the liquid pressure sensor body, a locator connected to the center of the inside of the bracket, and a buzzer connected to the outer edge of the inside of the bracket.

[0013] The positioner and buzzer are both threadedly connected to the inside of the bracket via a stud in the middle of one end.

[0014] The wiring section is connected to the middle of the upper end of the liquid pressure sensor body;

[0015] Insulating protective part, connected to the wiring part.

[0016] Furthermore, the bracket is arranged in a hollow column shape, and the front part of the outer surface of the bracket is equidistantly threaded, and is threadedly connected to the screw hole opened at the corresponding position on the middle part of the outer surface of the liquid pressure sensor body.

[0017] Furthermore, a control post is connected to the center of the bracket, and anti-slip textures are evenly distributed on the outer surface of the control post;

[0018] Furthermore, the bracket has through holes equidistantly spaced along its outer edge, and the inner edge of the through holes is positioned close to the location where the buzzer emits sound.

[0019] Specifically, the bracket is connected to the liquid pressure sensor body via threads and can be easily disassembled. The control post, with its anti-slip texture, facilitates the application of force required for the bracket's assembly and disassembly, while the through hole diffuses the sound generated by the buzzer.

[0020] Furthermore, the wiring section includes a guide tube connected to the middle of the upper end of the liquid pressure sensor body, a terminal extending into the guide tube, and a wire connected to the upper end of the terminal.

[0021] Furthermore, the outer surface of the guide tube is uniformly coated with an insulating layer;

[0022] The lower end of the electrical contact post is electrically connected to the corresponding electrical contact hole opened at the upper end of the liquid pressure sensor body.

[0023] Furthermore, the lower part of the outer surface of the guide tube is provided with threads at equal intervals, and the upper middle edge of the liquid pressure sensor body is provided with a threaded groove, and the two are threadedly connected.

[0024] Specifically, the guide tube is structurally supported and guided by the electrode post to extend into the liquid pressure sensor body. Through the sleeve between it and the electrode hole, the liquid pressure sensor can be powered and data can be transmitted. The connection between the screw groove and the thread connects the guide tube and the liquid pressure sensor body and can be easily disassembled. The insulation layer ensures the external insulation safety of the guide tube.

[0025] Furthermore, the insulating protective part includes a ring frame connected to the outer edge of the upper end of the guide tube and an insulating corrugated tube connected to the upper end of the ring frame;

[0026] The non-expansion length of the insulating corrugated pipe is three times the length of the electrical terminal on its inner side;

[0027] Furthermore, a sealing cap is connected to the center of the upper end of the insulating corrugated pipe, and an opening is provided through the center of the sealing cap, with the inner wall of the opening in contact with the outer surface of the connecting wire.

[0028] Furthermore, the lower end of the ring frame is interlocked with the annular groove formed on the outer edge of the upper end of the guide tube;

[0029] Specifically, the ring groove is used to secure the ring frame and install and fix the insulating corrugated tube. The telescopic insulating corrugated tube, in conjunction with the sealing cap, provides external shielding protection for the telescopic electrical terminals. The telescopic length of the insulating corrugated tube is three times that of the electrical terminal, which meets the external shielding requirements and can also be used for other longer electrical terminals.

[0030] 3. Beneficial effects

[0031] Compared with the prior art, the advantages of this invention are:

[0032] I. This invention provides a locator on the outer surface of each liquid pressure sensor body, which can be used to determine the location of a faulty or damaged liquid pressure sensor body. At the same time, a buzzer is provided, which can be used to further determine the location of the liquid pressure sensor body after the approximate location is determined, making it convenient and improving maintenance efficiency.

[0033] II. This utility model adopts a socket connection method, connecting the connecting wire to the liquid pressure sensor body, and can be extended and retracted by applying a force that moves up and down, allowing for fine adjustment of the length of the connecting wire to meet usage requirements.

[0034] Third, based on the second beneficial effect, a link is set on the outer edge of the upper end of the guide tube to connect the insulating corrugated tube. The insulating corrugated tube can be used to shield the telescopic electrical terminals to reduce the accident rate.

[0035] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0046] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0047] Example 1

[0048] Please see Figure 4 As shown, this embodiment is a pressure sensor for detecting liquids, including:

[0049] Liquid pressure sensor body 1;

[0050] The fault location unit 2 includes a bracket 21 connected to the middle of the outer surface of the liquid pressure sensor body 1, a locator 22 connected to the center of the inside of the bracket 21, and a buzzer 23 connected to the outer edge of the inside of the bracket 21.

[0051] Positioner 22 and buzzer 23 are both threadedly connected to the inside of bracket 21 via a stud in the middle of one end;

[0052] The bracket 21 is a hollow column, and the front part of the outer surface of the bracket 21 is equidistantly threaded, and is threadedly connected to the screw hole opened at the corresponding position in the middle of the outer surface of the liquid pressure sensor body 1.

[0053] The center of the bracket 21 is connected to the control post 24, and the outer surface of the control post 24 is equidistantly covered with anti-slip textures.

[0054] The bracket 21 has through holes equidistantly through its outer edge, and the inner edge of the through holes is set close to the sound-emitting position of the buzzer 23.

[0055] The following steps are provided on how to use the fault location unit 2:

[0056] By using the control post 24 with anti-slip texture, the bracket 21 is connected to the outer surface of the liquid pressure sensor body 1 via threads, while the positioner 22 and the buzzer 23 are respectively connected to the inner side of the bracket 21 via studs.

[0057] After a liquid pressure sensor body 1 is damaged, its position can be located by the locator 22 on the body, so that maintenance personnel can roughly determine its location. After the buzzer 23 is activated, the position can be checked more accurately for subsequent maintenance.

[0058] The aforementioned rapid location and processing facilitates improved efficiency in subsequent maintenance operations.

[0059] Example 2

[0060] Please see Figure 1-2 As shown, this embodiment is based on the above embodiment 1, and further includes a wiring part 4, which is connected to the middle part of the upper end of the liquid pressure sensor body 1;

[0061] The wiring section 4 includes a guide tube 41 connected to the middle of the upper end of the liquid pressure sensor body 1, a terminal 42 extending into the guide tube 41, and a wire 43 connected to the upper end of the terminal 42.

[0062] The outer surface of the guide tube 41 is uniformly coated with an insulating layer;

[0063] The lower end of the electrical contact post 42 is electrically connected to the corresponding electrical contact hole opened at the upper end of the liquid pressure sensor body 1.

[0064] The lower part of the outer surface of the guide tube 41 is equidistantly threaded, and the upper middle edge of the liquid pressure sensor body 1 is provided with a threaded groove, and the two are threadedly connected.

[0065] The following steps explain how to use the wiring section 4:

[0066] After placing one end of the power connector 42 inside the guide tube 41, the liquid pressure sensor body 1 can be powered and a subsequent data transmission can be performed through the sleeve connection between it and the power connector hole. The power connector 42 can extend and retract inside the power connector hole. While ensuring the electrical connection between the two, it can be extended and retracted to finely adjust the length of the power connector 43.

[0067] As described above, no additional extension is required for the connecting wire 43, which facilitates use and meets the requirements.

[0068] Example 3

[0069] Please see Figure 3 As shown, this embodiment, based on the above embodiment 1, further includes an insulating protective part 3, which is connected to the wiring part 4;

[0070] The insulating protective part 3 includes a ring frame 31 connected to the outer edge of the upper end of the guide tube 41 and an insulating corrugated tube 32 connected to the upper end of the ring frame 31;

[0071] The non-expanded length of the insulating corrugated pipe 32 is three times the length of the electrical terminal 42 located inside it;

[0072] A sealing cap 33 is connected to the center of the upper end of the insulating corrugated pipe 32, and an opening is provided through the middle of the sealing cap 33, with the inner wall of the opening in contact with the outer surface of the connecting wire 43.

[0073] The lower end of the ring frame 31 is engaged with the annular groove at the outer edge of the upper end of the guide tube 41.

[0074] The following steps are provided on how to use the insulation protection part 3:

[0075] When the extension and retraction of the connecting post 42 is finely adjusted, the outer edge of the upper end of the guide tube 41 can be pre-fixed by the ring frame 31. An insulating corrugated tube 32 is connected to the upper end of the ring frame 31. The length of the insulating corrugated tube 32 can be adjusted by applying a force to extend and retract it. With the help of the sealing cover 33, the extension and retraction of the connecting post 42 can be shielded and protected.

[0076] The above-mentioned external shielding protection, which uses insulated corrugated tube 32 to connect to electrical post 42 for adjustment, is highly applicable and can be folded and stored later, reducing the storage space occupied.
