[0032] like Figures 1 to 5 As shown, in an embodiment of the present invention, the driving part includes: a threaded rod 22, which is rotatably arranged in the shell 21; a motor 27, and the threaded rod 22 is connected to the output shaft of the motor 27; a connecting assembly, which is movably arranged in the shell 21, and the connecting assembly is threadably matched with the threaded rod 22, and the connecting assembly forms a first driving end 23.

[0033] In the above technical solution, the motor 27 drives the threaded rod 22 to rotate through the output shaft, so that the connecting assembly moves relative to the housing 21, thereby driving the first movable part 25 to move, so as to facilitate the movement of the second movable part 26. In this way, the second movable part 26 can drive the detection component 1 to move, so that density detection can be performed at different positions in the salt field.

[0034] Specifically, in the embodiment of the present invention, the connecting assembly is fixedly connected in the first moving portion 25 .

[0035] Specifically, in the embodiment of the present invention, a support seat is provided on the shell 21, one end of the threaded rod 22 is drive-connected to the output shaft of the motor 27, and the other end of the threaded rod 22 is rotatably provided on the support seat, and a space groove is provided in the first movable part 25 for avoiding the support seat, and the space groove is slidably matched with the support seat.

[0036] Specifically, in the embodiment of the present invention, the motor 27 is a three-phase asynchronous motor, so that the motor 27 can achieve forward and reverse rotation.

[0037] like Figures 1 to 3 As shown, in an embodiment of the present invention, along the moving direction of the first movable part 25, the first movable part 25 has a first end and a second end relatively arranged, the first driving end 23 is arranged on the first end, and the driving part also includes a driving wheel 231, the driving wheel 231 is transmission-connected to the threaded rod 22, and the driving wheel is rotatably arranged on the first driving end 23; the driven wheel 244 is rotatably arranged on the second end; the conveyor belt 242, the conveyor belt 242 is located at the outer periphery of the driving wheel 231 and the driven wheel 244, and the conveyor belt 242 is connected to the second movable part 26.

[0038] In the above technical solution, the rotating threaded rod 22 can drive the driving wheel 231 to rotate, and the driving wheel 231 drives the driven wheel 244 to rotate through the conveyor belt 242. In this way, the second movable part 26 can move relative to the first movable part 25, and the second movable part 26 can drive the detection component 1 to move, thereby realizing density detection at different positions in the salt field.

[0039] Specifically, in the embodiment of the present invention, the moving directions of the first moving portion 25 and the second moving portion 26 are both the length direction of the housing 21 .

[0040] Specifically, in the embodiment of the present invention, the diameters of the driving wheel 231 and the driven wheel 244 are equal, and the driving wheel 231 and the driven wheel 244 are spaced apart along the length direction of the shell 21, so that the linearity of the conveyor belt 242 during operation can be ensured.

[0041] In one embodiment, a transmission chain may be further provided. The transmission chain is located at the periphery of the driving wheel 231 and the driven wheel 244 . The driving wheel 231 and the driven wheel 244 are both sprockets.

[0042] like Figures 1 to 5 As shown, in an embodiment of the present utility model, the connecting assembly includes: a connecting member 234, the connecting member 234 is fixedly connected to the first moving portion 25, the connecting member 234 is movably arranged relative to the housing 21, the connecting member 234 is threadedly engaged with the threaded rod 22, and the driving wheel 231 is rotatably arranged on the connecting member 234; a first driving gear 233, the first driving gear 233 is threadedly engaged with the threaded rod 22, and the first driving gear 233 is rotatably arranged in the connecting member 234; a first driven gear 232, the first driven gear 232 is rotatably arranged relative to the connecting member 234, the first driven gear 232 is meshed with the first driving gear 233, and the first driven gear 232 is connected to the driving wheel 231.

[0043] In the above technical solution, the rotating threaded rod 22 drives the connecting member 234 to move along the length direction of the shell 21, so that the first driving gear 233 moves. Since the first driving gear 233 is threadedly engaged with the threaded rod 22, the first driving gear 233 can be rotated, and the rotating first driving gear 233 drives the driving wheel 231 to rotate through the first driven gear 232. In this way, the driving wheel 231 can drive the driven wheel 244 to rotate through the conveyor belt 242, so that the second moving part 26 can move relative to the first moving part 25, so that the second moving part 26 drives the detection component 1 to move, so as to realize density detection at different depths in the salt field.

[0044] Specifically, in the embodiment of the present invention, the connecting member 234 is a connecting block, and the connecting member 234 is fixedly connected in the first moving portion 25 .

[0045] Specifically, in the embodiment of the present invention, the first driving gear 233 and the first driven gear 232 are both bevel gears, and the angle between the first driving gear 233 and the first driven gear 232 is 90°.

[0046] Specifically, in the embodiment of the present invention, the first driven gear 232 and the driving wheel 231 are fixedly connected.

[0047] like Figures 1 to 3 As shown, in the embodiment of the present invention, the driving portion further includes a fixed block, which is connected to the conveyor belt 242 and fixedly connected to the second moving portion 26 , and the fixed block forms the second driving end 243 .

[0048] In the above technical solution, the driving wheel 231 can drive the driven wheel 244 to rotate through the conveyor belt 242, so that the conveyor belt 242 can drive the fixed block to move, and the fixed block can drive the second movable part 26 to move, so that the second movable part 26 drives the detection component 1 to move, thereby realizing density detection at different depths in the salt field.

[0049] Specifically, in the embodiment of the present invention, the fixing block is fixedly connected in the second moving portion 26 , and the fixing block is fixedly connected to the conveyor belt 242 .

[0050] Specifically, in the embodiment of the present invention, a fixing member 245 is fixedly connected to the second end of the first moving portion 25 . An opening is provided at one end of the fixing member 245 , and the opening is used to accommodate the driven wheel 244 and the conveyor belt 242 .

[0051] In the prior art, under the natural evaporation environment of the salt pan, the salt concentration gradually increases until salt mineral crystals precipitate from the brine and settle at the bottom of the salt pan, forming a condensed salt layer. Specifically, when the detection component of the salt pan liquid level density measurement device enters the salt pan, it may be interfered by the condensed salt layer, causing the detection component to be unable to penetrate to the predetermined depth smoothly, thereby affecting the accurate measurement of the salt pan density. Therefore, if Figure 4 and Figure 5 As shown, in an embodiment of the present invention, the salt field liquid level density measuring device also includes: a fixed shell 32, the telescopic component 2 is movably arranged relative to the fixed shell 32, and the fixed shell 32 is provided with a through hole; a movable member 313, which slides with the through hole, and one end of the movable member 313 is connected to the telescopic component 2; an elastic member 38, which is located in the fixed shell 32, and the other end of the movable member 313 is connected to the elastic member 38, and the elastic member 38 is used to provide an elastic driving force to the movable member 313 away from the fixed shell 32.

[0052] In the above technical solution, the elastic member 38 can provide an elastic driving force to the movable member 313. By setting the movable member 313 and the fixed shell 32 in a sliding fit, the movable member 313 can be moved along the length direction of the shell 21 in the direction away from the fixed shell 32. In this way, the telescopic component 2 can be moved along the length direction of the shell 21 in the direction away from the fixed shell 32, so that the telescopic component 2 can break through the solidified salt field, so that the detection component 1 can smoothly penetrate to the predetermined depth in the salt field, thereby ensuring the accuracy of the salt field density measurement.

[0053] like Figure 4 and Figure 5As shown, in the embodiment of the utility model, elastic piece 38 includes elastic piece 35;First cylinder 36, one end of first cylinder 36 is connected with moving piece 313, the other end of first cylinder 36 is abutted with elastic piece 35, first cylinder 36 is movably arranged relative to fixed shell 32;Second cylinder 37, one end of second cylinder 37 is connected with fixed shell 32, the other end of second cylinder 37 is abutted with elastic piece 35.

[0054] In the above technical solution, by compressing elastic piece 35, elastic piece 35 will provide an elastic pushing force, so that first cylinder 36 moves along the length direction of shell 21 to the direction away from second cylinder 37, so that first cylinder 36 drives moving piece 313 to move along the length direction of shell 21 to the direction away from fixed shell 32, so that telescopic component 2 moves along the length direction of shell 21 to the direction away from fixed shell 32, so that telescopic component 2 breaks through the salt field that has been condensed, and then the measurement of salt field density is completed.

[0055] Specifically, in the embodiment of the utility model, first cylinder 36 and second cylinder 37 are both cylindrical, and first cylinder 36 is rotationally connected with moving piece 313.

[0056] Specifically, in the embodiment of the utility model, elastic piece 35 is a spring, and elastic piece 35 can provide an elastic pushing force for first cylinder 36 when compressed.

[0057] Specifically, in the embodiment of the utility model, fixed shell 32 includes a first shell segment and a second shell segment connected, the diameter of the first shell segment is smaller than that of the second shell segment, and shell 21 is sleeved on the outer periphery of the first shell segment, so that the appearance of the salt field liquid level density measuring device can be ensured, thereby avoiding the phenomenon that telescopic component 2 protrudes from fixed shell 32.

[0058] Specifically, in the embodiment of the utility model, the salt field liquid level density measuring device further includes a bearing, the bearing includes an inner ring and an outer ring, the outer ring of the bearing is fixedly connected with the second shell segment, and the inner ring of the bearing is fixedly connected with second cylinder 37.

[0059] Specifically, in the embodiment of the utility model, elastic piece 35 will provide an elastic pushing force after rotating half a circle.

[0060] As Figure 4 And Figure 5As shown, in an embodiment of the present invention, the elastic member 38 is rotatably arranged relative to the fixed shell 32, and the elastic member 38 also includes a plurality of guide members 33, and the plurality of guide members 33 are located on the outer periphery of the first cylinder 36, and each guide member 33 is spirally arranged around the axis of the first cylinder 36; the salt field liquid level density measuring device also includes a plurality of contact members 34 arranged corresponding to the plurality of guide members 33, one end of each contact member 34 is connected to the fixed shell 32, and the other end of each contact member 34 extends to the corresponding guide member 33 and abuts against the side of the corresponding guide member 33 facing the movable member 313.

[0061] In the above technical solution, the first cylinder 36 is rotated, and under the action of the contact member 34, the guide member 33 will carry the first cylinder 36 to move along the length direction of the shell 21 toward the direction close to the second cylinder 37, thereby compressing the elastic member 35 and causing the elastic member 35 to rotate. When the elastic member 35 is compressed to a certain extent, the elastic member 35 will generate an elastic driving force. In this way, the elastic member 35 will rotate in the opposite direction and push the first cylinder 36 to move away from the second cylinder 37, so that the first cylinder 36 drives the movable member 313 to move along the length direction of the shell 21 toward the direction away from the fixed shell 32, and the telescopic member 2 moves along the length direction of the shell 21 toward the direction away from the fixed shell 32. In this way, the telescopic member 2 can break through the solidified salt field, thereby completing the detection of the salt field density.

[0062] Preferably, in an embodiment of the present invention, the guide member is a guide rib, and there are two guide members 33. The spiral arrangement of the guide members 33 can enable the contact member 34 to guide the guide member 33 to move when the first cylinder 36 rotates, so that the elastic member 35 can store force, and each guide member 33 includes a first end and a second end. Along the axial direction of the first cylinder 36, the first end of one contact member 34 is located above the second end of the other contact member 34, so that the guide member 33 can always abut against the contact member 34.

[0063] Specifically, in the embodiment of the present invention, the axial direction of the first column 36 is the length direction of the housing 21 .

[0064] Preferably, in the embodiment of the present invention, there are two contact members 34 , which are arranged in parallel in the fixed housing 32 , and the contact members 34 are cylindrical in shape.

[0065] Specifically, in the embodiment of the present invention, when the elastic member 35 rotates, the second column 37 rotates along with the elastic member 35 .

[0066] like Figure 4 and Figure 5As shown, in an embodiment of the present invention, the motor 27 is located in the moving part 313, and the salt field liquid level density measuring device also includes: a second driving gear 311, located in the moving part 313, the second driving gear 311 is connected to the outer periphery of the output shaft of the motor 27, and one end of the threaded rod 22 extends into the moving part 313; a second driven gear 312, located in the moving part 313, and the second driven gear 312 is located at the outer periphery of the first cylinder 36, and the second driven gear 312 is meshed with the second driving gear 311; wherein, when the output shaft of the motor 27 rotates, the second driving gear 311 drives the first cylinder 36 to rotate through the second driven gear 312, and when the output shaft of the motor 27 rotates in the opposite direction, the first cylinder 36 and the second driven gear 312 rotate in coordination.

[0067] In the above technical solution, the output shaft of the motor 27 drives the threaded rod 22 to rotate, and the second driving gear 311 drives the first column 36 to rotate through the second driven gear 312. Under the action of the contact member 34, the guide member 33 will carry the first column 36 to move along the length direction of the shell 21 toward the direction close to the second column 37, thereby compressing the elastic member 35 and causing the elastic member 35 to rotate. When the elastic member 35 is compressed to a certain extent, the elastic member 35 will generate an elastic driving force. In this way, the elastic member 35 will rotate in the opposite direction and push the first column 36 to move away from the second column 37, so that the first column 36 drives the movable member 313 to move along the length direction of the shell 21 toward the direction away from the fixed shell 32, so that the telescopic component 2 moves along the length direction of the shell 21 toward the direction away from the fixed shell 32. In this way, the telescopic component 2 can break through the solidified salt field and pop out continuously, helping the detection component 1 to complete the detection of the salt field density.

[0068] Specifically, in the embodiment of the present invention, when the motor 27 rotates forward, the second driven gear 312 drives the first cylinder 36 to rotate in the Figure 4 Rotate in clockwise direction.

[0069] Specifically, in the embodiment of the present invention, the second driving gear 311 and the second driven gear 312 are self-locking, and when the motor 27 rotates forward, the first cylinder 36 can be locked. Figure 4 The middle gear rotates and moves in the clockwise direction. When the motor 27 rotates in the reverse direction (the reverse rotation of the motor 27 means rotating in the opposite direction of the forward rotation of the motor 27), the second driven gear 312 rotates in the clockwise direction. Figure 4 The first column 36 does not rotate or move; similarly, the elastic member 35 drives the first column 36 to rotate in the counterclockwise direction. Figure 4 When the first cylinder 36 rotates counterclockwise, the first cylinder 36 will not drive the second driven gear 312 to rotate.

[0070] Specifically, in the embodiment of the present invention, the rotating threaded rod 22 drives the moving member 313 to move along the length direction of the housing 21 toward the second column 37 via the first column 36. The distance of the moving member 313 approaching the second column 37 is A, and the rotating threaded rod 22 drives the detection component 1 to move away from the second column 37 through a distance B. The distance B is greater than the distance A. In this way, the detection component 1 can be extended.

[0071] Specifically, in the embodiment of the present invention, a one-way clutch is provided between the first column 36 and the second driven gear 312. In this way, the second driven gear 312 can only drive the first column 36 to rotate in a single direction. When the rotation direction of the second driven gear 312 changes, the second driven gear 312 will not drive the first column 36 to rotate (that is, the second driven gear 312 rotates in coordination with the first column 36). Similarly, the reverse rotation of the first column 36 will not drive the second driven gear 312 to rotate. The specific structure of the one-way clutch can refer to the existing technology and will not be repeated here.

[0072] like Figure 1 As shown, in the embodiment of the present invention, the salt field liquid level density measuring device further includes a display component 4 , which is disposed on the fixed shell 32 and is electrically connected to the detection component 1 .

[0073] Through the above arrangement, the detection component 1 can display the detected data through the display component 4, so as to record the data intuitively.

[0074] Specifically, in the embodiment of the present invention, the display component 4 is a data display screen.

[0075] Specifically, in the embodiment of the present invention, the display assembly 4 is fixedly connected to the second shell section of the fixed shell 32 .

[0076] Specifically, in the embodiment of the present invention, the working principle of the salt field liquid level density measuring device is as follows: when the motor 27 rotates forward, the motor 27 drives the threaded rod 22 to rotate through the output shaft, and the rotating threaded rod 22 drives the connecting piece 234 to move along the length direction of the shell 21, so that the first moving part 25 moves relative to the shell 21 along the length direction of the shell 21 toward the direction away from the display component 4, the first driving gear 233 drives the driving wheel 231 to rotate through the first driven gear 232, and the driving wheel 231 can drive the driven wheel 244 to rotate through the conveyor belt 242, and the second driving end 243 provided on the conveyor belt 242 can drive the second moving part 26 to move along the length direction of the shell 21 toward the direction away from the display component 4. In this way, the first moving part 25 can be extended while the second moving part 26 can also be extended. At the same time, the rotating threaded rod 22 drives the second driven gear 312 to rotate through the second driving gear 311, so that the first cylinder 36 rotates, and the contact piece 310 is rotated. Under the action of 34, the guide member 33 will carry the first column 36 to move along the length direction of the shell 21 toward the second column 37, thereby compressing the elastic member 35 and causing the elastic member 35 to rotate. When the elastic member 35 is compressed to a certain extent, the elastic member 35 will generate an elastic driving force. In this way, the elastic member 35 will rotate in the opposite direction and push the first column 36 to move in the direction away from the second column 37, so that the first column 36 drives the movable member 313 to move along the length direction of the shell 21 toward the direction away from the fixed shell 32, so that the telescopic component 2 moves along the length direction of the shell 21 toward the direction away from the fixed shell 32. In this way, the telescopic component 2 can break through the solidified salt field. When the detection component 1 reaches the predetermined position, the motor 27 is turned off. The detection component 1 will transmit data and transmit it to the display component 4 for display after analysis. After the detection is completed, the motor 27 is turned on again, the motor 27 is reversed, and the first movable part 25 and the second movable part 26 are retracted into the shell 21.

[0077] Specifically, in an embodiment of the present invention, the salt field liquid level density measuring device can perform multi-stage extension and retraction of the detection component 1 through the telescopic component 2, and can detect data at different depths to ensure the accuracy of the data. The shell 21 and the first movable part 25 and the second movable part 26 can cover the detection requirements of various depths, and the first movable part 25 and the second movable part 26 can be retracted into the shell 21, thereby improving the convenience of the salt field liquid level density measuring device. Moreover, through the cooperation of the first driving gear 233 and the first driven gear 232, the second movable part 26 can be extended and retracted while the first movable part 25 is extended and retracted, thereby reducing the extension and retraction time of the salt field liquid level density measuring device, thereby improving the detection speed while improving convenience.

[0078] Specifically, in an embodiment of the present invention, the telescopic component 2 is continuously ejected by the elastic member 38, and after the salt field liquid level density measuring device enters the salt field, the elastic force stored in the contact member 34 and the guide member 33 can be used to break through the condensed salt, so that the salt field liquid level density measuring device can adapt to more environments and perform detection, and through the connection between the second driven gear 312 and the second driving gear 311, only one motor 27 is needed to drive the salt field liquid level density measuring device, which reduces the complexity of the salt field liquid level density measuring device, can improve the applicability of the salt field liquid level density measuring device while facilitating maintenance.

[0079] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: when it is necessary to detect the liquid level density of the salt field, by driving the first driving end to move the first movable part relative to the shell, and by driving the second driving end to move the second movable part relative to the first movable part, the second movable part can drive the detection component to move. In this way, compared with the prior art liquid level density and temperature measuring device for salt fields that can only perform detection at a certain position in the salt field, in this embodiment, by setting the first movable part and the second movable part that are movably arranged relative to the shell, and the second movable part is fixedly connected to the detection component, in this way, on the one hand, the detection component can measure the density of different positions in the salt field, thereby avoiding the phenomenon of only detecting a certain position in the salt field, avoiding the occurrence of inaccurate detection data, and improving the detection quality of the salt field liquid level density; on the other hand, it can also improve the convenience of using the salt field liquid level density measuring device.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
