Description

Technical Field

[0001] The utility model relates to the technical field of protection and monitoring, in particular to a groundwater level monitoring device with a protection function. Background Art

[0002] Strengthening the protection of groundwater resources has become one of the important tasks of environmental protection. An integrated groundwater level monitoring and protection measurement device can monitor indicators such as groundwater level and water quality in real time, and give an alarm in time, which helps to detect groundwater pollution problems early and protect groundwater resources. Groundwater is one of the important water resources indispensable in human life and industrial production. It is not only used for drinking water supply, but also widely used in agricultural irrigation, industrial production and ecological environment maintenance. Therefore, the monitoring and protection of groundwater resources are crucial.

[0003] In the prior art, groundwater is usually sampled and monitored by drilling wells. In order to avoid the interference of the external natural factors or human factors on the environment in the well, a wellhead protection device is usually provided at the wellhead. However, the wellhead protection device is separated from the measurement device, and the wellhead protection device cannot adapt to wellheads of different sizes and must be customized in advance. In addition, traditional monitoring means include methods such as groundwater level monitoring wells and water quality sampling, but these methods are often time-consuming and laborious, and the monitoring data cannot be collected in time.

[0004] Therefore, it is necessary to propose a groundwater level monitoring device with a protection function. Content of the Utility Model

[0005] In order to overcome the problems in the prior art such as poor protection effect resulting in sundries falling into the well, the size needs to be customized, and it is inconvenient to measure the groundwater level, the utility model provides a protection device that can adapt to various wellhead sizes and does not need to be customized according to the size. Since a strong material is used, the damage caused by impact can also be avoided.

[0006] The technical solution of the utility model is as follows:

[0007] A groundwater level monitoring device with a protection function is arranged outside the wellhead and includes a plurality of protection bodies. The plurality of protection bodies are arranged at intervals around the wellhead, and a guiding member is provided between adjacent protection bodies. A guiding groove cooperating with the guiding member is provided on the protection body, and the protection body can slide along the guiding member to approach or move away from its adjacent protection body;

[0008] A transparent telescopic cover is provided above the protected body. The edge of the transparent telescopic cover is connected to the upper part of several protected bodies. A telescopic umbrella-shaped support structure is provided at the center of the transparent telescopic cover. The telescopic umbrella-shaped support structure includes a vertical moving rod and several telescopic rods. A first spring and a sliding ring are sleeved outside the moving rod. The upper end of the first spring is connected to the moving rod, and the lower end is connected to the sliding ring. One end of several telescopic rods is hinged to the sliding ring and extends outward in an umbrella shape, and the extending end is connected to the edge of the transparent telescopic cover;

[0009] It also includes a measurement terminal. The measurement terminal is connected to a measurement front end through a measurement line. The measurement front end extends into the wellhead, and a floating ball is provided at its upper end.

[0010] Preferably, the guiding member is fixedly connected to one of two adjacent protected bodies and slides in the guiding groove of the other protected body.

[0011] Preferably, a second spring is provided between two adjacent protected bodies. When the moving rod moves vertically to reduce the acting force of the first spring on the telescopic rods, several protected bodies can move inward under the action of the second spring, reducing the diameter formed by them and reducing manual operation.

[0012] In order to control the movement of several protected bodies, a stop device is provided on the protected body. The stop device is located above the guiding groove and includes a stop gear and a braking buckle. The braking buckle can be telescopically abutted against the teeth of the stop gear. A stop tooth cooperating with the stop gear is provided at the top of the guiding member, and the stop tooth extends in a rack shape towards two adjacent protected bodies.

[0013] The braking buckle can lock and unlock the rolling of the stop gear. When it is necessary to move the protected body, the locking of the stop gear is released, and two adjacent protected bodies move towards each other or in the opposite direction, and the stop gear rolls on the stop tooth. When it is not necessary to move the protected body, the stop gear is locked so that it cannot rotate. Due to the cooperation relationship between the stop gear and the stop tooth, two adjacent protected bodies cannot move towards each other or in the opposite direction, thereby locking the size of the shape and diameter formed by several protected bodies.

[0014] Among them, the braking buckle includes a clip moving horizontally and a button for controlling the movement of the clip. One end of the clip is stuck between adjacent teeth of the stop gear, and a third spring is provided between the other end and the protected body to provide the force for the clip to abut against the stop gear through the third spring.

[0015] In order to facilitate controlling the size of the shape of the outer edge of the transparent telescopic cover, the upper part of the moving rod is threadedly connected to the transparent telescopic cover, and a rotary valve is provided at its upper end. The rotary valve and the first spring are located outside and inside the transparent telescopic cover respectively. By rotating the rotary valve, the moving rod is controlled to rise and fall, and then the sliding ring is driven to move up or down through the first spring, and further the size of the shape of the outer edge of the transparent telescopic cover is changed through the telescopic rods.

[0016] Preferably, a ring groove is provided on the moving rod, and the upper end of the first spring is stuck in the ring groove and can rotate relative to the moving rod.

[0017] Preferably, a hook is provided at the lower end of the moving rod, and an automatic winch is suspended on the hook. After the measuring line is wound by the automatic winch, both ends are respectively connected to the measuring front end and the measuring terminal. Since the automatic winch is directly above the wellhead, a section of the measuring line connected to the measuring front end extends vertically, so as to control the vertical movement of the measuring front end through the automatic winch.

[0018] In order to prevent dust, sundries, etc. from entering the well, a sealing ring is provided at the edge of the transparent telescopic cover for sealing connection with a plurality of protection bodies to improve the sealing performance.

[0019] In order to integrate the transparent telescopic cover with the protection body, facilitate the transparent telescopic cover to cover the protection body, and at the same time be able to be easily opened for operations such as maintenance and replacement of the devices inside, the transparent telescopic cover of the present application is hinged to the top of a protection body, and a handle is provided at a position on the side of the transparent telescopic cover opposite to the hinge.

[0020] A groundwater level monitoring device with a protection function provided by the present utility model has the following beneficial effects compared with the prior art:

[0021] (1) According to the specific size of the wellhead, several protection bodies can be moved to change the size of the shape they enclose to adapt to the wellhead, effectively solving the problem that traditional wellhead protection devices need to be customized.

[0022] (2) The groundwater data is obtained through the measuring front end and transmitted to the measuring terminal through the measuring line for display, effectively solving the problem of complex process for extracting groundwater level data.

[0023] (3) Through the stop device and the telescopic umbrella-shaped support structure, the sizes of the protection body and the transparent telescopic cover can be adjusted and locked, effectively solving the problem of insecure connection between the traditional wellhead protection device and the wellhead.

[0024] (4) The integrated monitoring, protection and measurement device has a simple structure and is easy to disassemble.

[0025] (5) It can prevent sundries at the wellhead from falling into the well and reduce the damage to the wellhead caused by external factors. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As Figure 1 , Figure 2 and Figure 3 shown, the embodiment of the present utility model provides a groundwater level monitoring device with a protection function, which is arranged outside the wellhead for protecting the wellhead and monitoring the groundwater at the same time.

[0036] The monitoring device includes a plurality of protection main bodies 1, which are arranged at intervals around the wellhead, and guide members 11 are provided between adjacent protection main bodies 1. A guide groove (not shown in the figure, but those skilled in the art should be able to know the structural shape of the guide groove according to the fact that the guide member 11 is inserted horizontally into the guide groove) is provided on the protection main body 1 and is matched with the guide member 11. The protection main body 1 can slide along the guide member 11 to approach or move away from its adjacent protection main body 1.

[0037] Through the cooperation of the guide member 11 and the guide groove, a plurality of protection main bodies 1 are connected together. When two adjacent protection main bodies 1 approach each other, the interface size of the shape formed by the plurality of protection main bodies 1 will become smaller, and vice versa, so as to adapt to wellheads of different diameters.

[0038] In this embodiment, the protection main body 1 is plate-shaped, vertically arranged, and has an arc-shaped cross-section. A plurality of protection main bodies 1 together form a circle.

[0039] The guiding member 11 is plate-shaped, and is fixedly connected to one of the two adjacent protection bodies 1, and slides in the guiding groove of the other protection body 1. One side edge of the guiding member 11 is fixed to the side edge of one protection body 1, and the other opposite side edge of the guiding member 11 is inserted into the guiding groove of the other protection body 1, covering the gap between the two adjacent protection bodies 1 to prevent sundries from entering the monitoring device and falling into the well.

[0040] Above the protection body 1, there is a transparent telescopic cover 2. The edge of the transparent telescopic cover 2 is connected to the upper part of several protection bodies 1, covering several protection bodies 1 to form a sealed space inside the monitoring device to protect the wellhead and prevent sundries from entering.

[0041] At the center of the transparent telescopic cover 2, there is a telescopic umbrella-shaped support structure 3. Please refer to Figure 4 simultaneously. The telescopic umbrella-shaped support structure 3 includes a vertical moving rod 31 and several telescopic rods 32. A first spring 33 and a sliding ring 34 are sleeved outside the moving rod 31. The upper end of the first spring 33 is connected to the moving rod 31, and the lower end is connected to the sliding ring 34. One end of several telescopic rods 32 is hinged to the sliding ring 34 and extends outward in an umbrella shape, and the extending end is connected to the edge of the transparent telescopic cover 2.

[0042] When the moving rod 31 moves upward, it drives the upper end of the first spring 33, stretching the first spring 33. Under the elastic force of the first spring 33, the lower end of the first spring 33 pulls the sliding ring 34 upward, causing several telescopic rods 32 to contract inward, and then pulling the outer edge of the transparent telescopic cover 2 inward to reduce the radius size of its edge to cooperate with the inward movement of several protection bodies 1. Conversely, when the moving rod 31 moves downward, several telescopic rods 32 open, increasing the radius size of the edge of the transparent telescopic cover 2.

[0043] The reason for using the first spring 33 to drive the sliding ring 34 instead of directly driving the sliding ring 34 by the moving rod 31, and using telescopic rods 32 instead of a straight rod is to play a buffering role when reducing the transparent telescopic cover 2 instead of a rigid connection to avoid damaging the transparent telescopic cover 2.

[0044] In this embodiment, in order to facilitate controlling the size of the shape of the outer edge of the transparent telescopic cover 2, the upper part of the moving rod 31 is threadedly connected to the transparent telescopic cover 2, and a rotary valve 35 is provided at its upper end. The rotary valve 35 and the first spring 33 are respectively located outside and inside the transparent telescopic cover 2. By rotating the rotary valve 35, through the threaded cooperation between the moving rod 31 and the transparent telescopic cover 2, the rising and falling of the moving rod 31 are controlled, and then the amount of inward contraction and outward expansion of the outer edge of the transparent telescopic cover 2 is controlled.

[0045] In order to avoid the first spring 33 being affected by the rotation of the moving rod 31, a ring groove 311 is provided on the moving rod 31, and the upper end of the first spring 33 is stuck in the ring groove 311 and can rotate relative to the moving rod 31.

[0046] A plurality of telescopic rods 32 are preferably arranged at uniform intervals circumferentially along the sliding ring 34 and extend downward in an umbrella shape.

[0047] A hook 36 is provided at the lower end of the moving rod 31, and an automatic winch 37 is suspended on the hook 36. The monitoring device further includes a measurement terminal 4. The measurement terminal 4 is connected to a measurement front end 5 through a measurement line 6. The measurement front end 5 extends into the wellhead, and a floating ball 7 is provided at its upper end.

[0048] Preferably, the measurement line 6 is wound around the automatic winch 37 and then connected to the measurement front end 5 and the measurement terminal 4 respectively at both ends. Since the automatic winch 37 is located directly above the wellhead, the measurement line 6 at the extension of the measurement terminal 4 is vertically downward connected to the measurement front end 5 after changing direction through the automatic winch 37, so as to control the vertical movement of the measurement front end 5 through the automatic winch 37.

[0049] The measurement terminal 4 can be installed outside a protection body 1.

[0050] As Figure 6 shown, the automatic winch 37 specifically includes a wire winding roller 371, a motor 372 located on one side of the wire winding roller 371, and a power supply line 373 connected to the motor 372.

[0051] As Figure 1 shown, a second spring 8 is provided between two adjacent protection bodies 1. When the moving rod 31 moves vertically, reducing the acting force of the first spring 33 on the telescopic rod 32, a plurality of protection bodies 1 can move inward under the action of the second spring 8, reducing the diameter of the circle they enclose and reducing manual operation.

[0052] Please also refer to Figure 5 shown. In order to control the movement of a plurality of protection bodies 1, a stop device 12 is provided on the protection body 1. The stop device 12 is located above the guide groove and includes a stop gear 121 and a brake buckle 122. The brake buckle 122 is telescopically abutted against the teeth of the stop gear 121. A stop tooth 111 cooperating with the stop gear 121 is provided at the top of the guide member 11, and the stop tooth 111 extends in a rack shape towards two adjacent protection bodies 1.

[0053] Among them, the brake buckle 122 includes a clip 1221 that moves horizontally and a button 1222 that controls the movement of the clip 1221. One end of the clip 1221 is stuck between adjacent teeth of the stop gear 121, and a third spring 1223 is provided between the other end and the protection body 1 to provide the force for the clip 1221 to abut against the stop gear 121 through the third spring 1223.

[0054] The braking buckle 122 can lock and unlock the rolling of the stop gear 121. When it is necessary to move the protection body 1, the locking of the stop gear 121 is released, and two adjacent protection bodies 1 move towards or away from each other, and the stop gear 121 rolls on the stop teeth 111. When it is not necessary to move the protection body 1, the stop gear 121 is locked and cannot rotate. Due to the matching relationship between the stop gear 121 and the stop teeth 111, two adjacent protection bodies 1 cannot move towards or away from each other, thereby locking the size of the shape and diameter formed by a plurality of protection bodies 1.

[0055] For another example Figure 1 As shown, in order to prevent dust, debris, etc. from entering the well, a sealing ring 21 is provided at the edge of the transparent telescopic cover 2 for sealing connection with a plurality of protection bodies 1 to improve the sealing performance.

[0056] In order to integrate the transparent telescopic cover 2 with the protection body 1, facilitate the transparent telescopic cover 2 to cover the protection body 1, and at the same time facilitate opening for operations such as maintenance and replacement of the devices therein, the transparent telescopic cover 2 of the present application is hinged to the top of a protection body 1, for example, connected by a hinge. A handle 22 is provided at a position on the transparent telescopic cover 2 opposite to the hinged position.

[0057] The specific implementation method is as follows:

[0058] The first step is to place the monitoring device above the wellhead of the monitoring point.

[0059] The second step is to press the button 1222 of the stopping device 12, and the clip 1221 contracts inward, so that the stop gear 121 can roll on the stop teeth 111.

[0060] The third step is to rotate the rotary valve 35 to drive the first spring 33 to move. The first spring 33 drives the telescopic rod 32 to contract inward or expand outward according to the inward or outward movement of the protection body 1. The transparent telescopic cover 2 is pulled by the telescopic rod 32, and its size changes accordingly. Due to the change of the radius of the edge of the transparent telescopic cover 2, the size of the protection body 1 connected to it also changes correspondingly under the action of the second spring 7 or manually through the stopping device 12.

[0061] The fourth step is that when the monitoring device changes to be closely connected to the wellhead of the monitoring point, the monitoring front end connected to the measurement line 6 is put into the wellhead of the monitoring point through the measurement terminal 4. When the float ball connected to the monitoring front end floats up, it means that the monitoring front end reaches the monitoring position.
