Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipe network monitoring, in particular to a fixing device and a monitoring system. Background Art

[0002] Establishing a monitoring system for urban drainage pipe networks can obtain the environmental information of drainage pipe networks in real time, facilitating the understanding of the dynamic operation status of drainage pipe networks. Currently, in order to obtain environmental information such as water quality and water volume of drainage pipe networks, sensors are usually installed in inspection wells of drainage pipe networks. However, the installation requirements of different sensors are different, and the sizes, shapes and depths of different inspection wells are also different. In some inspection wells, operators need to go down the well for installation, which may pose a danger to personal safety.

[0003] The prior art discloses a sensor installation bracket for urban drainage pipe networks that can avoid going down the well, as Figure 1 shown, including: two circular mounting frames 01, a telescopic mounting cross tube 02, an adjustable-length mounting longitudinal tube 03, and a sensor fixing cross plate 04. The mounting frame 01 is fixed at the wellhead of the pipe well through expansion bolts. The two ends of the mounting cross tube 02 are respectively welded to the mounting frame 01. The top end of the mounting longitudinal tube 03 is welded to a flange to form a movable flange 031. The movable flange 031 is installed on the mounting cross tube 02 and slides on the mounting cross tube 02. The sensor fixing cross plate 04 is fixedly welded to the bottom of the mounting longitudinal tube 03, and a sensor is fixed at the end.

[0004] In the above solution, by setting a telescopic mounting cross tube 02 and an adjustable-length mounting longitudinal tube 03, and sliding the mounting longitudinal tube 03 on the mounting cross tube 02, operators can complete the installation of the sensor outside the well and can adjust the installation position of the sensor according to the depth of the pipe well. However, the above solution can only adjust the installation height of the sensor and the position along the extending length direction of the mounting cross tube 02, and the adjustment ability is limited in the face of complex situations inside the pipe well.

[0063] The following will be described in conjunction withFigures 2 to 10 , describe embodiments of the present utility model.

[0064] According to an embodiment of the present utility model, on the one hand, a fixing device is provided for fixing an object to be installed within an object to be installed, including: a first fixing component 1, with both ends respectively fixed within the object to be installed; a second fixing component 2, one end connected to the first fixing component 1, and the other end for fixing the object to be installed, the second fixing component 2 being disposed at an angle to the first fixing component 1; a connecting component 3, slidably disposed on the first fixing component 1, the connecting component 3 being provided with a through hole, and the second fixing component 2 being inserted through the through hole for adjusting at least one of the following conditions of the second fixing component 2 under an external force: the position along the extending length direction of the first fixing component 1, the height relative to the first fixing component 1, and the rotation angle.

[0065] By fixing the first fixing component 1 within the object to be installed, with one end of the second fixing component 2 fixed to the first fixing component 1 and the other end for fixing the object to be installed, when fixing the object to be installed within the object to be installed, it is not necessary for an operator to enter the interior of the object to be installed for operation, but only to fix the fixing device to the object to be installed from the outside; by slidably arranging the connecting component 3 on the first fixing component 1 and inserting the second fixing component 2 through the through hole of the connecting component 3 for adjusting the position of the second fixing component 2 along the extending length direction of the first fixing component 1 and / or the height relative to the first fixing component 1 and / or the rotation angle under an external force, the horizontal position, height position, and any angular position of the object to be installed within the object to be installed can be adjusted, enabling the installation of the object to be installed to adapt to the complex conditions within the object to be installed.

[0066] In this embodiment, the object to be installed is a sensor, specifically a water quality monitoring sensor; the object to be installed is a pipe well, and both ends of the first fixing component 1 are respectively fixed to the side walls of the pipe well. As an alternative embodiment, the sensor can also be other water environment monitoring sensors such as a flow sensor, a flow velocity sensor, etc., and no further limitations are imposed here. As an alternative embodiment, the fixing device can also be used for other structures that require installing a detection piece within an opening, such as a pipe perpendicular to the ground, etc., and no further limitations are imposed here.

[0067] In this embodiment, the second fixing component 2 is perpendicularly disposed to the first fixing component 1. As an alternative embodiment, when the cross-sectional shape of the inner side wall of the pipe well is in a shape of an inverted V, a V shape, or other shapes, the included angle between the second fixing component 2 and the first fixing component 1 is adapted to the shape of the inner side wall of the pipe well and is arranged in a cross shape.

[0068] In order to adapt to the size of the wellhead of the pipe well, the first fixing component 1 in this embodiment includes two telescopically connectable fixing members. Specifically, as Figures 2 - 4 , Figure 10As shown in the figure, the first fixing assembly 1 includes: a third fixing member 13; and a fourth fixing member 14 provided with a groove, in which the third fixing member 13 is slidably provided, and the third fixing member 13 and the fourth fixing member 14 are fixed by bolts. Among them, the cross-section of the fourth fixing member 14 is in a "C" shape with an open upper part, serving as a sliding track; as Figure 8 shown, the first fixing assembly 1 is fixed at the middle position of the wellhead of the pipe well. By setting the first fixing assembly 1 to include two telescopically connectable fixing members, it can adapt to the sizes of different pipe well openings, so that both ends of the first fixing assembly 1 can be fixed to the side walls of the pipe well opening. As a transformable embodiment, the first fixing assembly 1 may also include three or four fixing members, which will not be limited here. As a transformable embodiment, it may also be that the third fixing member 13 and the fourth fixing member 14 are threadedly connected. As a transformable embodiment, it may also be that the first fixing assembly 1 is not telescopically arranged.

[0069] As Figures 2 - 4 , Figure 10 shown, the first fixing assembly 1 in this embodiment includes: two first plug-in members 11, respectively arranged at both ends after the two fixing members are connected; two second plug-in members 12 for fixedly connecting to the inner side walls of the pipe well opening, each second plug-in member 12 is respectively provided with a receiving cavity, and each first plug-in member 11 is respectively inserted into the receiving cavity. Among them, the first plug-in member 11 is a protrusion, respectively arranged below the third fixing member 13 and the fourth fixing member 14, and the second plug-in member 12 includes a fixing support, one side of the fixing support is provided with a sleeve, and the sleeve is provided with a receiving cavity, and the protrusion is inserted into the receiving cavity of the sleeve to form the installation of the first fixing assembly 1; the shapes of the protrusion and the receiving cavity are adapted to each other, both being cylindrical, for stably fixing the first fixing assembly 1 to the side wall of the pipe well. By inserting the first plug-in member 11 into the second plug-in member 12 to form the first fixing assembly 1, it is convenient for the installation and removal of the first fixing assembly 1. As a transformable embodiment, the shapes of the protrusion and the receiving cavity may also be square columns or other shapes, which will not be limited here.

[0070] As Figure 2 , Figure 8 shown, the second fixing assembly 2 in this embodiment includes: a first fixing member 21, one end of which is connected to the first fixing assembly 1; a second fixing member 22, one end of which is fixedly connected to the other end of the first fixing member 21, and the other end is used to fix the sensor, and the extending length direction of the second fixing member 22 forms an angle with the extending length direction of the first fixing member 21. Specifically, the extending length direction of the second fixing member 22 is perpendicular to the extending length direction of the first fixing member 21. By providing the second fixing member 22, the sensor can be adapted to the internal structure of the pipe well during installation. As a transformable embodiment, it may also be that the second fixing member 22 is not provided, but the sensor is directly fixed to the other end of the first fixing member 21.

[0071] As Figures 2 - 4 shown, the first fixing member 21 in this embodiment includes three fixing portions, and the extending length direction of the middle fixing portion forms an angle with the extending length directions of the other two fixing portions. Among them, the extending length direction of the middle fixing portion is parallel to the extending length direction of the first fixing assembly 1, and the extending length directions of the other two fixing portions are perpendicular to the extending length direction of the first fixing assembly 1. By setting the first fixing member 21 as three fixing portions and the extending length directions of the three fixing portions forming an angle, the first fixing member 21 can adapt to the setting mode of the inner wall of the pipe well. As a changeable embodiment, the number of the fixing portions of the first fixing member 21 and the extending direction are determined according to the specific situation of the inner wall of the pipe well, and no excessive limitation is made here.

[0072] As Figure 2 shown, the second fixing member 22 in this embodiment is a telescopic structure. Specifically, the second fixing member 22 includes a first socket member and a second socket member. The first socket member is provided with a first cavity, the second socket member is inserted into the first cavity of the first socket member, and a first bolt passes through the first socket member and the second socket member for fixation. By setting the second fixing member 22 as a telescopic structure, it can adapt to the internal structure of the pipe well. As a changeable embodiment, it can also be that the first socket member and the second socket member are fixed by a threaded connection method, or the second fixing member 22 is connected by a plurality of connection structures of the same size.

[0073] As Figure 3 、 Figure 6 、 Figure 9 shown, the connection assembly 3 in this embodiment includes: a first connecting member 31, slidably arranged on the first fixing assembly 1; a second connecting member 32, fixedly connected to the first connecting member 31, and the second connecting member 32 is provided with a through hole. Among them, the first connecting member 31 and the second connecting member 32 are separately arranged. By slidably arranging the first connecting member 31 on the first fixing assembly 1, the position of the second fixing assembly 2 along the extending length direction of the first fixing assembly 1 can be adjusted; by providing a through hole on the second connecting member 32 and inserting the second fixing assembly 2 into the through hole, the height and rotation angle of the second fixing assembly 2 relative to the first fixing assembly 1 can be adjusted. As a changeable embodiment, the first connecting member 31 and the second connecting member 32 can also be integrally arranged.

[0074] As Figure 3 、 Figures 5 - 7As shown in the figure, the cross-section of the first connecting member 31 in this embodiment is in an "L" shape. Specifically, the first connecting member 31 includes: a third connecting portion 311, which is slidably connected to the first fixing component 1; a fourth connecting portion 312, which is fixedly connected to the end of the third connecting portion 311 and is arranged at an angle with the third connecting portion 311, and the fourth connecting portion 312 is fixedly connected to the second connecting member 32. Among them, the third connecting portion 311 and the fourth connecting portion 312 are integrally arranged and are perpendicular to each other. As a transformable implementation manner, the third connecting portion 311 and the fourth connecting portion 312 can also be separately arranged, or, instead of arranging the fourth connecting portion 312, the second connecting member 32 can be directly fixedly connected to the end of the third connecting portion 311.

[0075] As Figure 3 , Figure 6 , Figure 9 As shown in the figure, the first connecting member 31 in this embodiment further includes a sliding member 313. One end of the sliding member 313 is connected to the third connecting portion 311, and the other end is slidably arranged in the groove. Further, an installation hole 3111 is provided on the third connecting portion 311, and the sliding member 313 is penetrated in the installation hole 3111, and one end of the sliding member 313 protrudes from the installation hole 3111. Among them, the sliding member 313 includes a slider and a connecting bolt. The slider is slidably arranged in the groove. The head of the connecting bolt is fixed in the installation hole 3111, and the threaded section extends into the groove and is threadedly connected to the slider. When the connecting bolt passes through the slider and abuts against the inner wall of the fourth fixing member 14, the position of the connecting component 3 on the first fixing component 1 is relatively fixed. As a transformable implementation manner, it can also be that the sliding member 313 is a double-headed bolt, one end of the double-headed bolt extends into the installation hole 3111, and the other end extends into the groove to form a sliding connection.

[0076] As Figure 3 , Figure 9 As shown in the figure, the installation hole 3111 in this embodiment is an elongated hole, and the extending length direction of the elongated hole is different from the extending length direction of the first fixing component 1, and is used for the sliding member 313 to slide in the installation hole 3111. Among them, the extending length direction of the elongated hole is perpendicular to the extending length direction of the first fixing component 1. By setting the installation hole 3111 as an elongated hole and the extending length direction of the elongated hole being different from the extending length direction of the first fixing component 1, the position of the second fixing component 2 perpendicular to the extending length direction of the first fixing component 1 can be adjusted, making the installation of the sensor more flexible. As a transformable implementation manner, it can also be that the position of the second fixing component 2 perpendicular to the extending length direction of the first fixing component 1 is adjusted by adjusting the distance between the first connecting member 31 and the second connecting member 32.

[0077] As Figure 3 , Figure 9As shown in the figure, the second connecting member 32 in this embodiment includes: a first connecting portion 321, the first connecting portion 321 includes a first recess; a second connecting portion 322, one end of which is detachably connected to the first connecting portion 321 through a fastener 323, the second connecting portion 322 includes a second recess, and the first recess and the second recess together define a through hole. Among them, the first connecting portion 321 is fixedly connected to the fourth connecting portion 312; one end of the first connecting portion 321 and the second connecting portion 322 is integrally provided, and the other end is separately provided, and the fastener 323 is fixedly connected to the separately provided ends of the first connecting portion 321 and the second connecting portion 322; the fastener 323 is a fastening bolt. By setting the second connecting member 32 to include the first connecting portion 321 and the second connecting portion 322 and fixing them through the fastener 323, the size of the through hole can be adjusted according to the size of the second fixing component 2, which is convenient for adjusting the position of the second fixing component 2; and after adjusting the position of the second fixing component 2, the fastener 323 can make the connection between the second fixing component 2 and the second connecting member 32 tighter, preventing the second fixing component 2 from falling off during use. As an alternative embodiment, it can also be that both ends of the first connecting portion 321 and the second connecting portion 322 are detachably connected, and both ends of the first connecting portion 321 and the second connecting portion 322 are fixedly connected through the fastener 323, so as to facilitate putting the second fixing component 2 into the through hole.

[0078] As Figure 2 shown, the fixing device in this embodiment includes: a third fixing component 4, the extended length of the third fixing component 4 is greater than the inner diameter of the pipe well, and one end of the third fixing component 4 is rotatably connected to the second fixing component 2, and the other end is used to abut against the first side wall of the pipe well under the action of an external force, so that the second fixing component 2 is fixed to the second side wall of the pipe well. Among them, the other end of the third fixing component 4 is arranged close to the first fixing member 21; the cross-section of the pipe well is circular, and the inner diameter is the diameter of the circle. By setting the extended length of the third fixing component 4 to be greater than the inner diameter of the pipe well, and rotatably connecting one end of the third fixing component 4 to the second fixing component 2, and the other end is used to abut against the first side wall of the pipe well under the action of an external force, the second fixing component 2 can be fixed to the second side wall of the pipe well, preventing the second fixing component 2 from shaking inside the pipe well, and further preventing the sensor from falling due to shaking or inaccurate measurement. As an alternative embodiment, the third fixing component 4 can also be arranged at the middle position or other positions of the second fixing component 2, and no more restrictions are made here. As an alternative embodiment, the cross-section of the pipe well can also be polygonal, and at this time the inner diameter is the maximum dimension of the polygon.

[0079] As Figure 2 shown, the fixing device in this embodiment includes: a lifting member 5, one end of which is connected to the other end of the third fixing component 4, and the other end is used for external operation. Specifically, as Figure 2As shown in the figure, the third fixing component 4 in this embodiment includes: a fixing body 41, which is arranged at an angle with the second fixing component 2; two fixing ends 42, which are respectively rotatably connected to both ends of the fixing body 41, and a lifting member 5 is connected to the fixing end 42 far from the second fixing component 2. Among them, the lifting member 5 is a lifting rope. When the lifting rope is not in use, the other end is tied to the first fixing component 1. When in use, it can be untied from the first fixing component 1. When the fixing device needs to be removed, the lifting rope is pulled upwards, and the angle between the third fixing component 4 and the second fixing component 2 changes, so that both the third fixing component 4 and the second fixing component 2 can be far away from the side wall of the pipe well. By setting the lifting member 5, the rotation angle of the third fixing component 4 can be controlled, preventing the third fixing component 4 from rotating to the maximum angle before the fixing device is fixed to the side wall of the pipe well and unable to abut against the side wall; and it can prevent the fixing device from accidentally falling into the well. As an alternative implementation, the other end of the lifting rope can also be fixed outside the pipe well, or at other positions such as the well wall or the wellhead of the pipe well as a safety towing rope, which is not limited here.

[0080] As Figure 2 shown, the third fixing component 4 in this embodiment is a telescopic structure. Specifically, the third fixing component 4 includes a third socket part and a fourth socket part. The third socket part is provided with a second cavity, and the fourth socket part is inserted into the second cavity of the third socket part, and a second bolt passes through the third socket part and the fourth socket part for fixation. By setting the third fixing component 4 as a telescopic structure, it can adapt to the internal structure of the pipe well.
