[0037] According to the embodiments of the utility model, a liquid level sensor structure is provided, comprising: a first fixing part 1, a liquid level detection part 2 is arranged on the first fixing part 1, which is used for detecting the liquid level of the liquid pipe 3, a second fixing part is slidably connected with the first fixing part 1 in the first direction, and the position of the fixed end of the second fixing part corresponds to the position of the liquid level detection part 2 in the first direction, which is used for clamping or releasing the liquid pipe 3 with the liquid level detection part 2, a driving part 4 is drivingly connected with the first fixing part 1 or the second fixing part, which is used for adjusting the distance between the fixed end of the second fixing part and the liquid level detection part 2 to the preset distance, so as to clamp the liquid pipe 3.

[0038] ​In the embodiment, the liquid level detecting member 2 is installed on the first fixing member 1, and the first fixing member and the second fixing member are slidably connected with each other. When the liquid level detecting member 2 needs to be installed on the liquid pipe 3, an external force is applied to one of the first fixing member and the second fixing member in the first direction, and the other one is fixed. The external force can be from the driving member or manually applied. The first fixing member and the second fixing member are slid in the first direction away from each other, so that the distance between the fixed end of the second fixing member and the liquid level detecting member is greater than the diameter of the liquid pipe. Then, the liquid pipe 3 is placed between the fixed end of the second fixing member and the liquid level detecting member 2. Then, under the driving action of the driving member 4, a reverse force is applied to adjust the distance between the fixed end of the second fixing member and the liquid level detecting member 2 to a preset distance, so as to be clamped on the liquid pipe 3 to be fixed, complete the installation of the liquid level detecting member 2, and detect the liquid level of the liquid pipe 3 in real time. When the liquid level detecting member 2 needs to be disassembled, the external force is applied again to make the first fixing member and the second fixing member slide in the first direction away from each other, so that the distance between the fixed end of the second fixing member and the liquid level detecting member 2 is greater than the diameter of the liquid pipe 3, and the liquid level detecting member 2 can be disassembled conveniently, quickly, time-savingly and labor-savingly. The liquid level detecting member 2 can be repeatedly used many times without the need of tools for disassembly and installation, and is not easy to be damaged during the disassembly and installation process, thereby prolonging the service life and saving the cost.

[0039] In one embodiment, as shown in Figure 2 、 Figure 3 、 Figure 8 and Figure 9 , the second fixing member includes a first fixing plate 5, a fixing rod 6 and a second fixing plate 7. The first fixing member 1 is slidably sleeved on the fixing rod 6. One end of the fixing rod 6 is connected with the first fixing plate 5, and the other end is connected with the second fixing plate 7. The position of the first fixing plate 5 corresponds to the position of the liquid level detecting member 2 in the first direction. The first fixing member 1 is provided with a cooperation plate 8 corresponding to the second fixing plate 7 in the first direction. The driving member 4 is drivingly connected with the first fixing member 1.

[0040] It should be noted that the first fixing plate 5 is the fixed end of the second fixing member. The axial direction of the fixing rod 6 is along the first direction. The driving member is connected with the second fixing plate, and the driving end thereof is drivingly connected with the first fixing member 1.

[0041] In this embodiment, the first fixing member 1 is sleeved on the fixing rod 6, and the first fixing plate 5 and the second fixing plate 7 are arranged at both ends of the fixing rod 6 respectively. When it is needed to fix the liquid level detection member 2 on the liquid pipe 3, an external force is applied on the cooperation plate 8, specifically, the second fixing plate 7 and the cooperation plate 8 are clamped by hands respectively, then the cooperation plate 8 is pressed and the force is applied towards the second fixing plate 7, so that the first fixing member 1 slides on the fixing rod 6, and then drives the liquid level detection member 2 to move away from the first fixing plate 5, so as to leave enough space, and then the whole is moved to the liquid pipe 3, which is arranged between the first fixing plate 5 and the liquid level detection member 2, then the cooperation plate 8 is released, and the force is applied on the second fixing member 1 in the reverse direction under the action of the driving member 4, which drives the first fixing member 1 to drive the liquid level detection member 2 to move towards the first fixing plate 5, until the first fixing plate 5 clamps the liquid pipe 3 with the liquid level detection member 2, and then the installation of the liquid level detection member 2 is realized. When disassembling, the force is applied on the first fixing member 1 through the cooperation plate 8 again, so that the distance between the first fixing plate 5 and the liquid level detection member 2 is greater than the diameter of the liquid pipe 3, so as to disassemble from the liquid pipe 3, which is convenient and fast.

[0042] As an embodiment of transformation, the second fixing member can also include the first fixing plate 5, the fixing rod 6 and the second fixing plate 7; the fixing rod 6 is slidably penetrated on the first fixing member 1; one end of the fixing rod 6 is connected with the first fixing plate 5, and the other end is connected with the second fixing plate 7; the position of the first fixing plate 5 corresponds to the position of the liquid level detection member 2 in the sliding direction; the first fixing member 1 is correspondingly provided with the cooperation plate 8 in the sliding direction of the second fixing plate 7; and the driving member 4 is drivingly connected with the second fixing plate 7. It should be noted that the driving member is connected with the first fixing member 1, and the driving end thereof is drivingly connected with the second fixing plate 7. The first fixing plate 5 and the second fixing plate 7 are slidably connected on the first fixing member 1 through the fixing rod 6. When it is needed to fix the liquid level detection member 2 on the liquid pipe 3, an external force is applied on the second fixing plate 7, and the first fixing member 1 is relatively fixed. Specifically, the second fixing plate 7 and the cooperation plate 8 are clamped by hands respectively, then the second fixing plate 7 is pressed and the force is applied, so that the fixing rod 6 drives the first fixing plate 5 to move away from the liquid level detection member 2, so as to leave enough distance, and then the whole is moved to the liquid pipe 3, which is arranged between the first fixing plate 5 and the liquid level detection member 2, then the second fixing plate 7 is released, and the force is applied on the second fixing plate 7 in the reverse direction under the action of the driving member 4, which drives the fixing rod 6 to drive the first fixing plate 5 to move towards the liquid level detection member 2, until the first fixing plate 5 clamps the liquid pipe 3 with the liquid level detection member 2, and then the installation of the liquid level detection member 2 is realized. When disassembling, the force is applied on the second fixing plate 7 again, so that the first fixing plate 5 is spaced apart from the liquid level detection member 2 by a preset distance, so as to disassemble from the liquid pipe 3, which is convenient and fast.

[0043] In one embodiment, as shown in FIG. 1, Figure 2 , Figure 3 , Figure 8And Figure 9 As shown in the figure, the driving member 4 is a compression spring; the compression spring is sleeved on the fixed rod 6 and located between the first fixing member 1 and the second fixed plate 7; the two ends of the compression spring abut against the first fixing member 1 and the second fixed plate 7 respectively.

[0044] It should be noted that the first fixing member 1 has a first state of sliding to a preset distance between the liquid level detecting member 2 and the first fixed plate 5 under the action of external force, and a second state of sliding to cooperate with the first fixed plate 5 to clamp the liquid pipe 3 under the elastic action of the compression spring; wherein the preset distance is greater than the diameter of the liquid pipe 3, so as to be separated from the liquid pipe 3 or to be clamped on the liquid pipe 3.

[0045] In this embodiment, the driving member 4 adopts a compression spring, which always abuts against the first fixing member 1 and the second fixed plate 7, and provides a force to the first fixing member 1 in the direction of the first fixed plate 5, so that the distance between the second fixed plate 7 and the first fixing member 1 becomes larger, and the distance between the first fixed plate 5 and the liquid level detecting member 2 becomes smaller, so as to facilitate the movement of the liquid level detecting member 2 in the direction of the first fixed plate 5 to clamp the liquid pipe 3 during installation; when disassembling is needed, the second fixed plate 7 is kept relative fixed, and an action force is applied to the cooperation plate 8 in the direction away from the first fixed plate 5, which drives the first fixing member 1 to move in the direction of compressing the compression spring and approaching the second fixed plate 7, so that the distance between the second fixed plate 7 and the first fixing member 1 becomes smaller, and the distance between the first fixed plate 5 and the liquid level detecting member 2 becomes larger, so as to loosen the liquid pipe 3 and complete the disassembly, which is simple, convenient and fast, can be repeatedly used, improves the maintenance efficiency and reduces the cost.

[0046] As a variable implementation, the driving member 4 can also adopt existing small linear motor, hydraulic cylinder or its elastic element, etc.

[0050] In this embodiment, the first arc-shaped groove 9 is provided on the first fixed plate 5 and adapted to the outer side wall of the liquid pipe 3, which improves the stability during clamping. The size of the first arc-shaped groove 9 can be adaptively set according to the diameter of different liquid pipes 3, which improves the versatility.

[0051] In one embodiment, asFigure 6 and Figure 7 As shown, the first fixing member 1 is provided with a through hole 10 that is adapted to and penetrates the fixing rod 6.

[0052] In this embodiment, the first fixing member 1 is sleeved on the fixing rod 6 by providing a through hole 10, which facilitates installation and disassembly.

[0053] In one embodiment, such as Figure 2 As shown, the fixing rod 6 has at least two rods.

[0054] In this embodiment, by setting at least two fixing rods 6, the stability during the sliding process is improved. Preferably, two fixing rods 6 are set to reduce costs while ensuring stability.

[0055] In one embodiment, such as Figure 6 and Figure 7 As shown, the first fixing member 1 is provided with a mounting groove 11 that is adapted to the liquid level detection member 2.

[0056] In this embodiment, by providing an installation groove 11 on the first fixing member 1 that is compatible with the liquid level detection member 2, the stability of the liquid level detection member 2 after installation is improved.

[0057] Specifically, the liquid level detection element 2 is a liquid level sensor.

[0058] Specifically, the liquid level detection element 2 is provided with a second arc-shaped groove on the side facing the first fixing plate 5, which is adapted to the outer wall of the liquid pipe 3, so as to improve the stability when clamping the liquid pipe 3.

[0059] In one embodiment, such as Figure 7 As shown, the first fixing member 1 has multiple threaded holes 12 corresponding to the liquid level detection member 2. The threaded holes 12 are used to connect the liquid level detection member 2 by screws.

[0060] In this embodiment, a threaded hole 12 is provided to facilitate the installation of the liquid level detection component 2 by screws, making installation and disassembly convenient.

[0061] In one embodiment, both the first fastener 1 and the second fastener are made of stainless steel.

[0062] In this embodiment, both the first fixing member 1 and the second fixing member are made of stainless steel to improve their service life.

[0063] The specific working principle of the liquid level sensor structure provided in this embodiment is as follows: the liquid level detection element 2 is installed to the first fixing element 1 by means of screw connection. When it is necessary to install the liquid level detection element 2 to the liquid pipe 3, such as Figure 8As shown, by clamping the second fixed plate 7 and the matching plate 8 with hands, pressing the matching plate 8 to exert a force towards the second fixed plate 7, or the second fixed plate 7 exerts a force towards the matching plate 8, or the second fixed plate 7 and the matching plate 8 exert forces towards each other, so that the first fixed part 1 and the second fixed plate 7 compress the compression spring and move towards each other, and then the first fixed part 1 moves on the fixed rod 6 relative to the side towards the second fixed plate 7, so that the distance between the first fixed plate 5 and the liquid level detecting part 2 is increased and kept at a preset distance, and then the liquid pipe 3 is placed between the first fixed plate 5 and the liquid level detecting part 2, and the first arc-shaped slot 9 and the second arc-shaped slot are adjusted to be aligned with the liquid pipe 3, and then as shown, Figure 9 As shown, the matching plate 8 is loosened, and under the elastic action of the compression spring, the second fixed plate 7 and the first fixed part 1 move away from each other, that is, the first fixed part 1 moves on the fixed rod 6 relative to the side towards the first fixed plate 5, so that the distance between the liquid level detecting part 2 and the first fixed plate 5 is reduced and the liquid pipe 3 is clamped between them, and the installation of the liquid level detecting part 2 is completed, so as to detect the liquid level of the liquid pipe 3 in real time; when it is necessary to disassemble the liquid level detecting part 2, as shown, Figure 8 As shown, by exerting a force on the second fixed plate 7 and the matching plate 8 with hands, the first fixed part 1 and the second fixed plate 7 move towards each other and compress the compression spring, so that the distance between the first fixed plate 5 and the liquid level detecting part 2 is greater than the diameter of the liquid pipe 3, and the liquid level detecting part 2 can be disassembled conveniently and quickly, and can be repeatedly used many times, and is not easy to be damaged during disassembly and installation, prolonging the service life and saving costs.
