[0001] The utility model relates to the technical field of water level detectors, in particular to a drop-in water level detector. Background Art

[0002] The liquid level detector (static pressure level gauge / liquid level sensor / liquid level sensor / water level sensor) is a pressure sensor that measures the liquid level. The submersible static pressure level transmitter (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensitive element or a ceramic capacitor pressure sensitive sensor to convert the static pressure into an electrical signal, which is then converted into a standard electrical signal after temperature compensation and linear correction.

[0003] Chinese utility model CN215114737U is a pressure type liquid level gauge, the wire and the liquid level gauge are detachable for easy transportation and storage. The principle is that a hole is opened at the connection end of one end of the wire, and by pressing one end of the transmission rod to rotate it, the other end drives the card block to rotate, and the sensor body and the connection end are inserted and connected. When the transmission rod is released, the spring retracts and drives the transmission rod to rotate in the opposite direction, inserting the card block into the hole to complete the fixation between the liquid level gauge body and the connection end.

[0004] However, the existing device needs to put the sensor into various liquids when in use to prevent the liquid from being mixed with a large amount of impurities or mud and sand, etc., which will enter the hole and block the hole, making it inconvenient to insert the block into the hole and requiring regular inspection and cleaning. Therefore, a immersion water level detector is designed to address the above problems. Utility Model Content

[0030] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field.

[0031] The liquid level detector (static pressure level gauge / liquid level sensor / liquid level sensor / water level sensor) is a pressure sensor that measures the liquid level. The submersible static pressure level transmitter (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensitive element or a ceramic capacitor pressure sensitive sensor to convert the static pressure into an electrical signal, which is then converted into a standard electrical signal after temperature compensation and linear correction.

[0032] In the related art, a hole is opened at the connection end of one end of the wire, and by pressing one end of the transmission rod to rotate it, the other end drives the card block to rotate, and the sensor body is inserted and connected with the connection end. When the transmission rod is released, the spring retracts and drives the transmission rod to rotate in the opposite direction, and the card block is inserted into the hole to complete the fixation between the liquid level meter body and the connection end. However, when using the existing device, the sensor needs to be put into various liquids to prevent a large amount of impurities or mud and sand from entering the hole and blocking the hole, making it inconvenient to insert the card block into the hole, and it needs to be checked and cleaned regularly.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a immersion water level detector. When the sensor body 11 and the connecting end 12 need to be disassembled for storage, it is only necessary to toggle the paddle 28 to drive the limiting ring 27 to rotate on the base 25 through the ring body 26 and disengage from the transmission rod 23, and then toggle the transmission rod 23. At this time, the connection between the transmission rod 23 and the base 1 22 rotates, so that the connection between the pull ring 24 and the hook 21 is loosened, and the pull ring 24 is rotated to disengage from the hook 21, so that the fixation between the sensor body 11 and the connecting end 12 can be released, and the disassembly can be completed by separating them. When it is necessary to assemble them together, it is necessary to dock the sensor body 11 and the connecting end 12, and then put the pull ring 24 on the hook 21, and rotate the transmission rod 23 to pull the pull ring 24 to tighten the sensor body 11 and the connecting end 12, and then rotate the limiting ring 27 to the top of the transmission rod 23 to limit and prevent rotation. The installation is completed.

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figure 1-Figure 4 The embodiment of the present application provides a immersion water level detector, including: a sensor body 11 having a connection end 12 at one end; a wire 13 arranged at one end of the connection end 12; a liquid level meter body 14 arranged at the other end of the wire 13; a connecting assembly 2 is symmetrically arranged on the outer side walls of the sensor body 11 and the connection end 12, and the connecting assembly 2 includes: a hook 21 arranged on the outer side wall of the connection end 12; a base 22 fixedly arranged on the outer side wall of the sensor body 11; a transmission rod 23 rotatably arranged on the base 22; two ends of a pull ring 24 are inserted into the outer side wall of one end of the transmission rod 23 and are rotatably connected to the transmission rod 23; a base 25 is fixedly arranged on the outer side wall of the sensor body 11; a ring body 26 is symmetrically sleeved on the base 25 and is rotatably connected to the base 25; the bottom of a limiting ring 27 is fixedly connected to the outer side wall of the ring body 26.

[0036] Specifically, when measuring the water level, the sensor body 11 needs to be thrown into the water, and the water level data is detected by pressure and displayed on the liquid level meter body 14. The principle is: when the immersion liquid level transmitter puts the sensor body 11 into a certain depth in the measured liquid, the pressure (P) on the sensor's liquid surface is related to the density of the measured liquid (p), the local gravity acceleration (g), the atmospheric pressure on the liquid surface (Po) and the depth (H) of the transmitter into the liquid. The pressure formula is: P = p·g·H+Po. The pressure of the liquid is introduced into the positive pressure cavity of the sensor through the gas-conducting stainless steel, and the atmospheric pressure Po on the liquid surface is connected to the negative pressure cavity of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is p·g·H. In this way, by measuring the pressure P, the liquid level depth H can be obtained. The immersion sensor body 11 consists of three parts: the liquid level transmitter body, the liquid level probe and the signal processing circuit. The liquid level probe transmits the hydraulic pressure to the pressure sensor in the liquid level transmitter body by immersing itself in the liquid. The pressure of the liquid will cause the elastic element in the pressure sensor to deform, which in turn causes the resistance of the sensitive element to change. Then, the signal processing circuit in the body of the liquid level transmitter measures the change in the resistance of the sensitive element and converts it into an analog voltage signal proportional to the liquid height or level. This signal is amplified, filtered and linearized by the circuit and converted into a digital quantity for output.

[0037] When the sensor body 11 and the connecting end 12 need to be disassembled for storage during use, it is only necessary to toggle the limiting ring 27 to rotate on the base 25 through the ring body 26 to disengage from the transmission rod 23, and then toggle the transmission rod 23. At this time, the connection between the transmission rod 23 and the base 1 22 rotates, so that the connection between the pull ring 24 and the hook 21 is loosened, and the pull ring 24 is rotated to disengage from the hook 21, so that the fixation between the sensor body 11 and the connecting end 12 can be released, and the disassembly can be completed by separating them. When it is necessary to assemble them together, it is necessary to dock the sensor body 11 and the connecting end 12, and then put the pull ring 24 on the hook 21, and rotate the transmission rod 23 to pull the pull ring 24 to tighten the sensor body 11 and the connecting end 12, and then rotate the limiting ring 27 to the top of the transmission rod 23 to limit and prevent rotation. The installation is completed.

[0038] In some embodiments, the width of the hook 21 is consistent with the inner width of the pull ring 24 .

[0039] When used, the same width can prevent it from moving easily after being fixed.

[0040] In some embodiments, the connection assembly 2 further includes: a paddle 28 disposed on the top of the restriction ring 27 .

[0041] When in use, it can be easily toggled, and the limiting ring 27 is driven to rotate by toggling the paddle 28 .

[0042] In some embodiments, the connecting component 2 further includes: a clockwork spring 29 is sleeved on the second base 25 , and two ends thereof are connected to the ring body 26 and the second base 25 .

[0043] When in use, the design of the clockwork spring 29 can stabilize the position of the ring body 26, so that the limiting ring 27 is always placed on the top of the transmission rod 23 to limit it.

[0044] In some embodiments, the connection assembly 2 further includes: a convex strip 291 disposed on the top of the transmission rod 23 .

[0045] When in use, the arrangement of the convex strip 291 can have a certain blocking effect on the limiting ring 27, so that it will not easily slide off the transmission rod 23.

[0046] In some embodiments, a plurality of convex strips 291 are provided, and all are arranged on the top of the transmission rod 23 .

[0047] When in use, multiple frictions are provided to increase the friction when the transmission rod 23 is pressed, so that it will not slip easily.

[0048] In some embodiments, a tension component 3 is symmetrically arranged on the outer wall of the connecting end 12, and the tension component 3 includes: a shell 31 fixedly arranged on the outer wall of the connecting end 12; a connecting rod 32 symmetrically has one end passing through the inner wall of the shell 31 and is fixedly connected to the hook 21; a baffle 33 is arranged at one end of the connecting rod 32; a spring 34 is arranged inside the shell 31, and its two ends are connected and fixed to the shell 31 and the baffle 33.

[0049] Specifically, two ends of the spring 34 are fixedly connected to the inner wall of the housing 31 and the baffle 33 by means of snap rings.

[0050] When in use, after being fixed, the spring 34 rebounds to push the baffle 33 to move inside the shell 31, which can pull the connecting rod 32 back into the shell 31, and at the same time drive the hook 21 to move to increase the firmness of the connection between the sensor body 11 and the connecting end 12.

[0051] In some embodiments, the spring 34 is sleeved on the outside of the housing 31 .

[0052] When in use, the spring 34 is limited by the connecting rod 32 when compressed and will not bend, thereby better protecting the spring 34.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0054] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
