DETAILED DESCRIPTION

[0026] The utility model embodiment provides a kind of small reservoir pressure measuring pipe orifice osmometer telescopic suspension and protection device, as shown in Figures 1-4 It is a top view structural schematic diagram of the utility model, including support base 101, lifting plate 107, pressure measuring pillar 108 and data cable 114, the support base 101 is discoid, the pressure measuring pillar 108 is equipped in the support base 101 below, the pressure measuring pillar 108 can be lifted and moved, the pressure measuring pillar 108 upper and lower two side end surfaces are fixed with the lifting plate 107 playing the role of support connection, the lifting plate 107 between two sides is equipped with spring and plays the effect of shock absorption, the pressure measuring pillar 108, the pressure measuring pillar 108 top is connected with data cable 114, the data cable 114 is threaded through top lifting plate 107 and extends upwards and is threaded through support base 101, the data cable 114 plays the effect of data output.

[0027] It needs to be further explained that the pressure measuring pillar 108 is equipped with several pressure measuring sensors, and the data of each pressure measuring sensor is output through data cable 114

[0028] Further, the lifting plate 107 top of upper side is equipped with vertical cable protection cylinder 115, the surface of cable protection cylinder 115 is equipped with screw thread, mounting plate 116 is installed on the outer end surface of cable protection cylinder 115, rubber pad is installed between mounting plate 116 and lifting plate 107.

[0029] It needs to be further explained that the data cable 114 is threaded through the inside of cable protection cylinder 115.

[0030] Further, the lifting hooks 106 are installed on both sides of the top end of the lifting plate 107, the lifting clasp 117 is sleeved on the top end of the lifting hook 106, and the lifting cable 118 is connected to the top end of the lifting clasp 117 on both sides.

[0031] Further, the lifting grooves 102 are arranged in the support base 101, the lifting grooves 102 are symmetrically arranged on both sides, the transmission shaft 119 is rotatably arranged between the two walls of the lifting groove 102, the lifting line wheel 111 is installed on the outer end surface of the transmission shaft 119, and the lifting cable 118 on both sides is connected to the lifting line wheel 111 on both sides.

[0032] Further, the transmission shaft 119 extends outward on one side and is provided with the rotating disc 103.

[0033] It is worth further explaining that when the rotating discs 103 on both sides are rotated, the rotating discs 103 are rotated and drive the lifting line wheels 111 on both sides to rotate through the transmission shaft 119, the lifting cable 118 connected to the lifting line wheels 111 on both sides is pulled up through the rotation of the lifting line wheels 111 on both sides, the lifting clasp 117 is pulled up through the cooperation and pulling of the lifting cable 118 on both sides, and the measuring pressure column 108 is lifted and moved through the support of the lifting hook 106 on both sides.

[0034] Further, the support base 101 is fixed with a plurality of support bases 113 at the bottom, the support bases 113 are arranged in an annular array, the support leg 110 is rotatably connected to the bottom of the support base 113, and the support plate 109 is hinged to the tail end of the support leg 110.

[0035] It should be noted that the support leg 110 and the support plate 109 are inclined and unfolded to support the support base 101.

[0036] Further, the support base 101 is provided with four open grooves 104 on the outer arc surface, the open grooves 104 are arc-shaped, and the arc-shaped protection plug plate 105 is installed in the open grooves 104 to support and protect.

[0037] Further, the support base 101 is fixed with a circular ring cylinder-shaped limiting protection plate 112 at the lower end, and the inner diameter of the limiting protection plate 112 is greater than the lifting plate 107.

[0038] When the scheme is used, first, the support base 101 is moved above the pressure measuring pipe of the small reservoir, the support leg 110 on four sides is inclined and rotated, the support plate 109 on each side is used to stabilize and support, the lifting clasp 117 on both sides above the measuring pressure column 108 is connected with the lifting cable 118, the measuring pressure column 108 is moved and inserted into the pressure measuring pipe, and the subsequent pipe mouth pressure measurement work is facilitated.

[0039] After successfully inserting the load cell 108 into the pressure pipe, the staff manually rotates the two side turntables 103, as the turntables 103 rotate, the transmission shafts 119 connected to them begin to rotate, in turn driving the two side lifting pulleys 111 to rotate through the transmission of the transmission shafts 119, and because the two side lifting pulleys 111 are respectively connected to the two side lifting cables 118, the rotation of the transmission shafts 119 will drive the two side lifting pulleys 111 to rotate synchronously, and through the support of the lifting clamps 117 and the lifting hooks 106, the entire load cell 108 assembly can be smoothly lifted and moved, and after adjusting the height position, the suspension work of the load cell 108 is completed.

[0040] During the lifting and adjusting process, the vertical direction guidance and protection of the limiting protection plates 112 can prevent the load cell 108 from colliding and rubbing with the buried ground of the pressure pipe during the lifting process due to the shaking of the load cell 108, and at the same time, the springs arranged between the lifting plates 107 play a shock-absorbing and buffering role, whether it is due to small errors in manual operation or slight vibrations caused by external environmental factors (such as wind, uneven ground, etc.), the springs can effectively absorb these vibration energies, ensuring that the load cell 108 and the pressure sensor inside it remain in a relatively stable state, thereby improving the accuracy and reliability of the measurement data.

[0041] At the same time, the installation of the mounting plate 116 not only provides a stable channel and protection for the data cable 114, but also facilitates subsequent maintenance or replacement of the data cable 114, and further enhances the sealing between the mounting plate 116 and the lifting plate 107 through the rubber gasket, preventing water or other impurities from seeping into the device through the gap and causing damage to electronic equipment.

[0042] In the subsequent pressure detection work, after the detection sensor inside the load cell 108 collects data, the detected data is integrated and output through the data cable 114, which is convenient for the staff to summarize and compare data.

[0043] When the measurement work is completed, the staff only needs to reverse the rotation of the two side turntables 103, so that the transmission shafts 119 and the lifting pulleys 111 are reversed, and the load cell 108 is smoothly lifted until it is completely withdrawn from the pressure pipe.

[0044] It is worth noting that the four arc-shaped openings 104 and the arc-shaped support protection plugs 105 inside the outer arc surface of the support base 101 not only enhance the overall structural strength of the device, but also provide an additional protective layer to prevent damage caused by accidental impact during transportation, installation or disassembly.

[0045] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
