Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit inclinometer equipment, in particular to a water absorbing structure for collecting a slope measuring device. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. After the foundation pit is excavated, supports will be arranged on the side walls of the foundation pit to ensure the safety of underground structure construction and the environment surrounding the foundation pit.

[0003] In order to ensure the smooth construction of the foundation pit and the foundation pit support, it is necessary to carry out corresponding slope measurement work on the foundation pit support. In the prior art, an inclinometer is often used to measure the slope of the foundation pit support. The inclinometer usually includes an inclinometer rod and a cable part. One end of the inclinometer rod is connected to the cable of the cable part, and the other end is suspended. When in use, the inclinometer rod is made to fall to the depth of the foundation pit support under the action of its own weight by laying out the cable part; and after the slope measurement is completed, the inclinometer rod is retracted by reeling in the cable part. However, when the inclinometer rod falls to the depth of the foundation pit support, the cable is very likely to be contaminated with groundwater, which undoubtedly brings troubles to the reeling operation. Utility Model Content

[0004] In order to overcome the above shortcomings, the purpose of the utility model is to provide a water absorption structure for winding up a slope measuring device, which can absorb water from the cable during the winding process, thereby avoiding the winding trouble caused by the cable getting wet.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a water absorbing structure for winding a slope measuring device, the slope measuring device includes a fixed housing, a guide tube, a cable part, and an inclinometer rod; the cable part is built in the fixed housing, and includes a winding drum with a cable wound; the guide tube is fixed to the fixed housing, and a guide channel connected to the fixed housing is penetrated thereon; the inclinometer rod is slidably arranged in the guide channel, and one end of the inclinometer rod is connected to the cable;

[0006] The water absorption structure includes a first water absorption part and a second water absorption part used in conjunction with each other. The first water absorption part is arranged at the junction of the guide channel and the fixed housing, and is provided with a water absorption channel for the cable to pass through; the second water absorption part is located between the first water absorption part and the winding drum, and can flexibly abut against the cable located between the winding drum and the first water absorption part; and the water absorption rate of the second water absorption part is greater than that of the first water absorption part.

[0007] During inspection, the guide pipe is inserted into the foundation pit support, and then the cable is unwound by the winding reel, so that the inclinometer rod pulls the cable down along the guide channel under the action of its own weight, so as to realize the measurement of the slope of the foundation pit by the inclinometer rod; when the measurement is completed, the cable is reeled up, and the cable can return from the guide channel to the fixed casing, thereby driving the inclinometer rod back to the guide channel.

[0008] The beneficial effects of the water absorption structure of the utility model are:

[0009] The first water absorption part is arranged between the guide channel and the fixed housing, so that the cable returning from the guide channel to the fixed housing can be subjected to the first water absorption treatment to remove the moisture attached to the cable; and then the second water absorption part located between the first water absorption part and the winding drum can be subjected to the second water absorption treatment to further remove the moisture attached to the cable before the cable is rewound onto the winding drum; and by setting the water absorption rate of the second water absorption part to be greater than the water absorption rate of the first water absorption part, the water absorption treatment of the cable by the second water absorption part is made more thorough, thereby ensuring the dryness of the cable rewound onto the winding drum.

[0010] Furthermore, the first water absorbing part includes a fixed tube and a first water absorbing member, the fixed tube is provided with a tube body channel matching the outer diameter of the first water absorbing member, the first water absorbing member is located in the tube body channel, the water absorbing channel is opened thereon, and the inner diameter of the water absorbing channel is adapted to the outer diameter of the cable. The inner diameter of the water absorbing channel is set to be adapted to the outer diameter of the cable, so that when the cable re-enters the water absorbing channel, a portion of the water and large particles of impurities (such as sludge, etc.) contained in the water can be directly filtered out due to the inner diameter limitation of the water absorbing channel; then, through the movement of the cable in the water absorbing channel, the first water absorbing member can be fully in contact with the cable to absorb the water on the cable.

[0011] Furthermore, the length of the tube channel is greater than the length of the first water absorbing member, so that there is space in the tube channel for filtering out some water and large particles of impurities.

[0012] Furthermore, a contact boss is provided on one side of the tube channel facing the fixed housing to limit the moving position of the first water absorbent member. During the process of winding the wire, due to the contact friction between the wire and the water absorption channel, the first water absorbent member may move toward the fixed housing. At this time, the provision of the contact boss can prevent the first water absorbent member from detaching from the fixed tube.

[0013] Furthermore, the first water absorbing member is made of felt material, which has a certain water absorbing property and can fully rub against the cable due to its surface roughness, so as to filter out impurities attached to the cable surface.

[0014] Furthermore, the cable part also includes a tensioning wheel mounted on the fixed housing. The second water absorbing part is arranged close to the tensioning wheel, and includes a water absorbing base and a second water absorbing member. The water absorbing base is fixed to the fixed housing, and the second water absorbing member is detachably arranged on the water absorbing base, and can flexibly abut against the cable wound on the tensioning wheel. By arranging the second water absorbing part at the tensioning wheel, the tensioning effect of the tensioning wheel on the cable can be utilized to ensure that the second water absorbing member can flexibly abut against the cable to absorb water on the cable.

[0015] Furthermore, the side of the water absorbing base facing the tensioning wheel is an arc surface matching the shape of the tensioning wheel, and an opening is provided on the arc surface. The setting of the arc surface can minimize the gap between the water absorbing base and the tensioning wheel, so as to facilitate full contact between the second water absorbing member and the cable.

[0016] Furthermore, the water absorbing base is provided with a receiving groove connected to the opening; the second water absorbing member is detachably arranged in the receiving groove and can partially extend out of the opening. The second water absorbing member is detachably arranged in the receiving groove, so that the second water absorbing member that is full of water can be replaced in time.

[0017] Furthermore, the accommodating groove is provided with a push column near the opening, and the push column can abut against the second water absorbing member, so that the second water absorbing member can partially extend out of the opening, ensuring that the second water absorbing member can contact the cable.

[0018] Furthermore, the second water absorbing member is made of a water absorbing sponge material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0026] Example

[0027] See attached Figure 1 As shown, an inclination measuring device includes a fixed housing 1, a guide tube 2, a cable part, and an inclinometer rod, wherein the cable part is built into the fixed housing 1, and includes a winding drum 3 on which a cable is wound, and a tensioning wheel 4 for tensioning the cable, one end of the cable is wound on the winding drum 3, and the other end enters the guide tube 2 after being tensioned by the tensioning wheel 4. The guide tube 2 is fixedly connected to the fixed housing 1, and a guide channel communicating with the fixed housing 1 is provided through the guide tube 2. The inclinometer rod is slidably arranged in the guide channel, one end of which is connected to the cable, and the other end is suspended. During inspection, the guide pipe 2 is inserted into the foundation pit support, and then the cable is unwound by the winding drum 3, so that the inclinometer rod pulls the cable down along the guide channel under the action of its own weight, so as to realize the measurement of the slope of the foundation pit by the inclinometer rod; when the measurement is completed, the cable is reeled on the winding drum 3, so that the cable can return from the guide channel to the fixed housing 1, and then drive the inclinometer rod back to the guide channel.

[0028] In order to prevent the cable from bringing groundwater into the fixed housing 1 during the cable reeling process, see the attached Figure 1-2 As shown, the utility model discloses a water absorbing structure for winding a slope measuring device, which includes a first water absorbing part 5 and a second water absorbing part 6 used in conjunction with each other. The first water absorbing part 5 is arranged at the junction of a guide channel and a fixed housing 1, and is provided with a water absorbing channel 51 for the cable to pass through; the second water absorbing part 6 is located between the first water absorbing part 5 and the winding drum 3, and can flexibly abut against the cable located between the winding drum 3 and the first water absorbing part 5; and the water absorption rate of the second water absorbing part 6 is greater than the water absorption rate of the first water absorbing part 5.

[0029] The first water absorption part 5 is arranged between the guide channel and the fixed housing 1, so that the cable returning from the guide channel to the fixed housing 1 can be subjected to the first water absorption treatment to remove the moisture attached to the cable; and then the second water absorption part 6 located between the first water absorption part 5 and the winding drum 3 can be subjected to the second water absorption treatment to further remove the moisture attached to the cable before the cable is rewound onto the winding drum 3; and by setting the water absorption rate of the second water absorption part 6 to be greater than the water absorption rate of the first water absorption part 5, the water absorption treatment of the cable by the second water absorption part 6 is made more thorough, thereby ensuring the dryness of the cable rewound onto the winding drum 3.

[0030] For details, see the attached Figure 2-3As shown, the first water absorbing part 5 includes a fixed tube 52 and a first water absorbing member 53. The fixed tube 52 is fixedly arranged at the junction of the guide channel and the fixed housing 1, and a tube body channel matching the outer diameter of the first water absorbing member 53 is arranged therein. The first water absorbing member 53 is located in the tube body channel, and a water absorbing channel 51 is opened thereon, and the inner diameter of the water absorbing channel 51 matches the outer diameter of the cable. The cable can be passed through the water absorbing channel 51, one end of which is connected to the inclinometer rod, and the other end is wound on the winding drum 3 after being tensioned by the tensioning wheel 4.

[0031] The inner diameter of the water absorption channel 51 is set to match the outer diameter of the cable, so that when the cable moves from the guide channel to the water absorption channel 51 (during the winding process), a part of the water on the cable and the large particles of impurities (such as sludge, etc.) contained in the water can be directly filtered out due to the limitation of the inner diameter of the water absorption channel 51; and then the cable moves in the water absorption channel 51, and the first water absorption member 53 is fully in contact with the cable to absorb the water on the cable.

[0032] For further information, see Appendix Figure 3 As shown, the length of the tube channel is greater than the length of the first water absorbing member 53. A contact boss 521 for limiting the moving position of the first water absorbing member 53 is provided on one side of the tube channel facing the fixed housing 1.

[0033] When releasing the line, the cable moves from the fixed housing 1 toward the guide channel. At this time, due to the contact friction of the cable on the first water absorbing member 53, the first water absorbing member 53 may move along the tube channel toward the guide channel. When reeling in the line, the cable moves from the guide channel toward the fixed housing. Due to the moisture attached to the cable, the cable can drive the first water absorbing member 53 to move along the tube channel toward the fixed housing 1, and then abut against the abutting boss 521. At this time, because the length of the tube channel is greater than the length of the first water absorbing member 53, space is reserved in the tube channel to accommodate moisture and large particles of impurities that cannot enter the water absorption channel 51 due to the inner diameter limitation of the water absorption channel 51.

[0034] Exemplarily, the first water absorbent member 53 is made of felt material. The felt material has a certain water absorption performance, and the surface roughness of the felt material can fully rub against the cable, which is more conducive to filtering out impurities attached to the cable surface.

[0035] In some embodiments, see Appendix Figure 1 , 4As shown, the second water absorbing part 6 is arranged near the tensioning wheel 4, and includes a water absorbing base 61 and a second water absorbing member. The water absorbing base 61 is fixedly connected to the fixed housing 1, and the second water absorbing member is detachably arranged on the water absorbing base 61, and can flexibly abut against the cable wound on the tensioning wheel 4. The second water absorbing part 6 is arranged at the tensioning wheel 4, and the tensioning effect of the tensioning wheel 4 on the cable can be utilized to ensure that the second water absorbing member can flexibly abut against the cable to absorb water on the cable.

[0036] Specifically, a receiving groove for receiving the second water absorbent member is provided in the water absorbent base 61, and the side of the water absorbent base 61 facing the tensioning wheel 4 is an arc surface matching the shape of the tensioning wheel 4, and an opening 611 connected to the receiving groove is provided on the arc surface. The setting of the arc surface can reduce the gap between the water absorbent base 61 and the tensioning wheel 4 as much as possible, so as to facilitate the full contact between the second water absorbent member and the cable.

[0037] The second water absorbent member is made of a water-absorbing sponge material and can be detachably arranged in the receiving groove. When the second water absorbent member is in the receiving groove, the second water absorbent member can partially extend out of the opening 611 and flexibly abut against the cable wound on the tensioning wheel 4. Exemplarily, a push column 612 is arranged near the opening 611 of the receiving groove, and the push column 612 can abut against the second water absorbent member, so that the second water absorbent member partially extends out of the opening 611, ensuring that the second water absorbent member can contact the cable.

[0038] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
